Screening for congenital hearing impairment with brainstem evoked response audiometry in isolated orofacial cleft

Brainstem evoked response audiometry (BERA) is the most established and recommended objective audiometric method for the clinical diagnosis of hearing impairment in high-risk infants. It is unclear whether infants with orofacial clefts meet the criteria for the high-risk group. This retrospective cohort study evaluated the need for diagnostic BERA in infants with cleft palate with or without cleft lip by assessing the predisposition to and diagnosis of congenital hearing impairment. Data from 122 patients treated at a single cleft centre were evaluated. BERA was conducted at the time of palate repair at 4-6 months of age. Clinical follow-up was analysed up to 4 years. The presence of a syndrome was examined as a risk factor for congenital hearing impairment. Among the 122 patients, four had congenital sensorineural or mixed hearing loss requiring hearing aids. All affected patients had syndromes in addition to the cleft. Most patients with elevated hearing thresholds had transient conductive hearing loss. Most suspected sensorineural hearing loss initially diagnosed was refuted. However, a higher incidence of sensorineural hearing loss was found in patients with syndromic clefts, supporting the diagnostic use of BERA with initial surgery only in patients with syndromic clefts.

Anxiety and depressive personality disorders in the modern world

The study's significance lies in the multitude of challenges facing individuals today, such as the COVID-19 pandemic, military conflicts like the war in Ukraine, and the escalating rates of cancer morbidity and mortality. These factors contribute to the onset of anxiety and depressive disorders, disrupting various aspects of individuals' mental functioning and social interactions. Addressing these disorders effectively necessitates a comprehensive approach, combining pharmacological interventions with psychotherapeutic strategies under the guidance of specialized professionals. In this regard, the study is aimed at identifying aspects and features of the development of psychological problems and personality disorders in the modern world filled with various stressors. The leading methods of studying this problem are analysis, synthesis, induction, deduction, comparison, experiment and systematisation of approaches that will help determine a wide range of mental disorders. Theoretical methods were used to analyze the literature and summarize theoretical material on anxiety and depressive disorders. Diagnostic methods were used to assess the psychological state of the study population. The study examines significant clinical syndromes and vegetative disorders that disrupt normal lifestyle, hinder daily activities, and impede professional growth. It evaluates the roles of psychologists, psychiatrists, and social workers in assisting individuals with anxiety disorders. It outlines preventive measures for anxiety and depression, while also delving into various types of anxiety disorders. The research proposes diverse methods to prevent emotional anxiety and instability. It underscores the importance of devising novel strategies for diagnosis and therapy, emphasizing a comprehensive approach involving psychotherapeutic support, medical intervention, and adaptive behavioral techniques. The findings of the study hold both practical and theoretical significance for professionals in psychology, psychiatry, psychoanalysis, and sociology who provide support for individuals with anxiety and depressive disorders. Furthermore, the insights provided may be pertinent to researchers and scholars investigating the psychological well-being of contemporary society amidst adverse external circumstances.

Paraneoplastic syndromes associated with classic Hodgkin lymphoma, a systematic literature review

PNS are uncommon manifestations of cancer. The current literature about these syndromes in the setting of cHL is disintegrated. A systematic literature review of all published literature was conducted. One hundred twenty-eight patients from 115 publications met the inclusion/exclusion criteria. Eight-five patients were of the NS subtype (66.4%). The most frequent clinical presentation of the PNS was CNS manifestation (25.8%). The majority of patients were diagnosed with the cHL and PNS simultaneously (42.2%). In 33.6% of patients, the lymphoma diagnosis preceded the PNS diagnosis. In 16.4% of patients, the PNS diagnosis preceded the lymphoma diagnosis. The presence of PNS antibodies was reported in 35 patients (27.3%). Age older than 18 was associated with higher prevalence of PNS. The CR rate of the lymphoma was 77.3%. The complete resolution rate of the PNS was 54.7%. Relapse of lymphoma was reported in 13 patients, and recurrence of the PNS upon relapse was reported in 10/13 patients.

Missed Maxillary Sinus Ostium Syndrome and its Management

The inflammatory process involving the maxillary sinus is often exacerbated by a functional obstruction due to laterally displaced uncinate process which obstructs the infundibulum and the natural ostium. Physiologically the drainage pathway may be adequate but during periods of inflammation resulting in nasal oedema, the ostium/infundibulum interface is inadequate, preventing adequate ventilation and drainage of the maxillary sinus. Incomplete removal of the uncinate process without including the natural ostium may result in failure and recurrence. This method of Middle meatal antrostomy that does not include the natural ostium of the maxillary sinus, leads to the missed ostium sequence and continued sinus disease. Here a case of missed maxillary sinus syndrome and its management is presented. A 28-year-old man with complaints of post nasal drip and Left facial pain for 4 months. 3 years prior the patient underwent functional endoscopic sinus surgery (FESS), following surgery patient had recurrent episode of sinusitis. Diagnostic nasal endoscopy revealed presence of mucopurulent discharge in left middle meatus, CT scan Paranasal sinus was suggestive of opacity in left maxillary sinuses and in left middle meatus with wide maxillary antrostomy. Revision FESS surgery was performed, where two ostia were present was converted into single wide middle meatal antrostomy using a back bitting forceps and microdebrider to avoid maxillary sinus mucus recirculation phenomenon. On follow up 1 year later, patient had no symptoms of repeated sinusitis. Missed maxillary sinus ostium syndrome has to be recognized and timely addressed by joining the natural and surgically created ostia as single wide middle meatal antrostomy window.

[Screening for Characteristic Genes of Different Traditional Chinese Medicine Syndromes of Psoriasis Vulgaris: A Study Based on Bioinformatics and Machine Learning]

Objective

To screen for the key characteristic genes of the psoriasis vulgaris (PV) patients with different Traditional Chinese Medicine (TCM) syndromes, including blood-heat syndrome (BHS), blood stasis syndrome (BSS), and blood-dryness syndrome (BDS), through bioinformatics and machine learning and to provide a scientific basis for the clinical diagnosis and treatment of PV of different TCM syndrome types.

Methods

The GSE192867 dataset was downloaded from Gene Expression Omnibus (GEO). The limma package was used to screen for the differentially expressed genes (DEGs) of PV, BHS, BSS, and BDS in PV patients and healthy populations. In addition, KEGG (Kyoto Encyclopedia of Genes and Genes) pathway enrichment analysis was performed. The DEGs associated with PV, BHS, BSS, and BDS were identified in the screening and were intersected separately to obtain differentially characterized genes. Out of two algorithms, the support vector machine (SVM) and random forest (RF), the one that produced the optimal performance was used to analyze the characteristic genes and the top 5 genes were identified as the key characteristic genes. The receiver operating characteristic (ROC) curves of the key characteristic genes were plotted by using the pROC package, the area under curve (AUC) was calculated, and the diagnostic performance was evaluated, accordingly.

Results

The numbers of DEGs associated with PV, BHS, BSS, and BDS were 7699, 7291, 7654, and 6578, respectively. KEGG enrichment analysis was focused on Janus kinase (JAK)/signal transducer and activator of transcription (STAT), cyclic adenosine monophosphate (cAMP), mitogen-activated protein kinase (MAPK), apoptosis, and other pathways. A total of 13 key characteristic genes were identified in the screening by machine learning. Among the 13 key characteristic genes, malectin (MLEC), TUB like protein 3 (TULP3), SET domain containing 9 (SETD9), nuclear envelope integral membrane protein 2 (NEMP2), and BTG anti-proliferation factor 3 (BTG3) were the key characteristic genes of BHS; phosphatase 15 (DUSP15), C1q and tumor necrosis factor related protein 7 (C1QTNF7), solute carrier family 12 member 5 (SLC12A5), tripartite motif containing 63 (TRIM63), and ubiquitin associated protein 1 like (UBAP1L) were the key characteristic genes of BSS; recombinant mouse protein (RRNAD1), GTPase-activating protein ASAP3 Protein (ASAP3), and human myomesin 2 (MYOM2) were the key characteristic genes of BDS. Moreover, all of them showed high diagnostic efficacy.

Conclusion

There are significant differences in the characteristic genes of different PV syndromes and they may be potential biomarkers for diagnosing TCM syndromes of PV.

Systematic review and illustrative case report

The coexistence of Moyamoya Syndrome with Arteriovenous Malformation is exceedingly rare. Here, we present the case of a 37-year-old female patient diagnosed with AVM in the right parietal lobe, accompanied by severe stenosis of the right middle cerebral artery and right anterior cerebral artery, along with moyamoya collateral induction. Our objective was to investigate the frequency and mutual influence of these conditions, and to determine a preferable treatment strategy by conducting a comprehensive review of previous case reports. We conducted a thorough search of PubMed, Scopus, and Web of Science databases, adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Our review encompassed 36 publications, reporting a total of 64 cases of AVM coexisting with Moyamoya Syndrome. Notably, bilateral stenosis was observed in half of the cases. Among patients with unilateral stenosis, AVM was localized in the opposite hemisphere only in 2 cases. Treatment approaches varied, with 18 cases undergoing active treatment for both stenosis and AVM, 11 cases treating stenosis prior to AVM, 5 cases addressing AVM first, and 3 cases treating both AVM and stenosis simultaneously. Embolization, either standalone or supplemented by stereotactic radiosurgery, was employed in six cases. Stereotactic radiosurgery alone was utilized in 12 cases, while 15 patients underwent surgical removal of the AVM. Our findings provide valuable insights for neurosurgeons managing patients with concurrent AVM and Moyamoya Syndrome. The variety of treatment approaches observed in the literature underscores the complexity of these cases, emphasizing the need for individualized strategies. This information may guide future systematic reviews and meta-analyses, contributing to a better understanding of the optimal management of these rare coexisting vascular pathologies.

Clinical and radiographic characteristics of pycnodysostosis: A systematic review

Purpose

Pycnodysostosis (PYCD), an autosomal recessive syndrome, is characterized by an imbalance in bone remodeling that produces various clinical and radiographic craniofacial manifestations. This review represents a systematic examination of these manifestations, as well as oral features associated with PYCD.

Materials and Methods

A systematic review was conducted across 8 databases from February to March 2023. The search strategy focused on studies reporting cases of PYCD that examined the clinical and radiographic craniofacial and oral characteristics associated with this syndrome.

Results

The review included 84 studies, encompassing a total of 179 cases of PYCD. More than half of the patients were female (55.3%), and the mean age was 14.7 years. Parental consanguinity was reported in 51.4% of the cases. The most common craniofacial clinical manifestation was a prominent nose, observed in 57.5% of cases. Radiographically, the most frequently reported craniofacial characteristics included the presence of an obtuse mandibular angle (84.3%) and frontal cranial bosses (82.1%). Clinical and radiographic examinations revealed oral alterations, with micrognathia present in 62.6% of patients and malocclusion in 59.2%. Among dental anomalies, tooth agenesis was the most commonly reported, affecting 15.6% of patients.

Conclusion

Understanding the clinical and radiographic craniofacial features of PYCD is crucial for dental professionals. This knowledge enables these clinicians to devise effective treatment plans and improve patient quality of life.

Understanding the Genetic and Non-Genetic Interconnections in the Aetiology of Syndromic Congenital Heart Disease: An Updated Review: Part 2

PURPOSE OF REVIEW

Approximately 30% of syndromic cases diagnosed with CHD, which lure us to further investigate the molecular and clinical challenges behind syndromic CHD (sCHD). The aetiology of sCHD in a majority of cases remains enigmatic due to involvement of multiple factors, namely genetic, epigenetic and environmental modifiable risk factors for the development of the disease. Here, we aim to update the role of genetic contributors including chromosomal abnormalities, copy number variations (CNVs) and single gene mutations in cardiac specific genes, maternal lifestyle conditions, environmental exposures and epigenetic modifiers in causing CHD in different genetic syndromes.

RECENT FINDINGS

The exact aetiology of sCHD is still unknown. With the advancement of next-generation technologies including WGS, WES, transcriptome, proteome and methylome study, numerous novel genes and pathways have been identified. Moreover, our recent knowledge regarding epigenetic and environmental regulation during cardiogenesis is still evolving and may solve some of the mystery behind complex sCHD. Here, we focus to understand how the complex combination of genetic, environmental and epigenetic factors interact to interfere with developmental pathways, culminating into cardiac and extracardiac defects in sCHD.

BRASH syndrome with a complete heart block- a case report

INTRODUCTION

BRASH syndrome (Bradycardia, Renal failure, Atrioventricular (AV) nodal blocking agent, Shock and Hyperkalemia) is a recently emerging diagnosis that describes the profound bradycardia seen in patients on AV nodal blockers who present with acute kidney injury (AKI) and hyperkalemia.

CASE PRESENTATION

We present a case of a 68 years old female patient with past history of hypertension taking atenolol and Enalapril presented to emergency department with the complaint of loss of consciousness of 02 hours duration. She had 03 days history of fatigue, poor oral intake, decreased urine output, appetite loss, vertigo and global headache. Her vital signs were blood pressure of 60/40 mmHg, absent radial pulse and temperature of 36.4 °C. Her systemic examination was remarkable for dry buccal mucosa; apical heart rate was 22 beats per minute. Glasgow Coma Scale was 13/15. Her laboratory tests showed creatinine of 1.83 mg/dL, blood urea nitrogen of 89 mg/dL and potassium elevated to the level of 6.39 mEq/dL. ECG revealed complete heart block with a normal QT interval and T waves and no U waves with ventricular rate of 22 beats per minute. Her previous medications were discontinued and the patient was resuscitated with intravenous (IV) fluids. She was given 03 doses of 1 mg atropine every 5 minutes but there was no increment in heart rate. She was given 50% dextrose with 10 international units of regular insulin, 1 g of calcium gluconate and Intravenous perfusion of norepinephrine and dopamine. Subsequently, after 14 hours of ICU admission the patient had a cardiac arrest with asystole and resuscitation was attempted but she couldn't survive.

CONCLUSION

BRASH syndrome is largely an under-recognized life threatening clinical diagnosis. Physicians should have high index of suspicion for BRASH when they encounter patients with bradycardia, hyperkalemia, and renal failure, as timely diagnosis is crucial in the management.

Predictors of sleep quality components in patients undergoing transarterial chemoembolisation: a cross-sectional study

PURPOSE

Patients undergoing transarterial chemoembolisation experience postembolisation symptoms and interferences affecting sleep quality, which require intervention. The study aimed to identify the predictors of sleep quality components in patients undergoing transarterial chemoembolisation.

METHODS

This study included two groups of participants: 50 patients undergoing transarterial chemoembolisation and 45 nurses caring for them. Data were collected from September to November 2022 using a structured questionnaire, and analysed using descriptive statistics, the t-test, analysis of variance, Spearman's rank correlation, and multiple regression analysis using the SPSS 27.0 program (IBM Corp., Armonk, NY, USA).

RESULTS

The mean sleep quality score was 40.28±14.10. Heat sensation (t=-2.08, p=.043) and fatigue (t=-4.47, p<.001) predicted sleep fragmentation in 38.6% of the patients. Abdominal pain (t=-2.54, p=.014), vomiting (t=-2.21, p=.032), and the expected fatigue by the nurses (t=2.68, p=.014) predicted sleep length in 41.7% of patients. Abdominal pain (t=-2.05, p=.046) explained 42.9% of sleep depth.

CONCLUSION

Based on the predictors of sleep quality components obtained in this study, strategies to improve sleep quality tailored to patients undergoing transarterial chemoembolisation should be developed. This study highlighted the need to bridge the gap between patients' and nurses' expected fatigue and its contribution to sleep fragmentation and sleep length. It also highlighted the importance of noncontact temperature measurement, controlling vomiting, and pain relief for improving sleep length in patients undergoing transarterial chemoembolisation.

The terminologies of transient, migratory, or localized osteoporosis, and bone marrow edema syndrome: a scoping review

There is no formally defined terminology for the related entities transient osteoporosis of the hip (TOH), localized or regional migratory osteoporosis (RMO) and bone marrow edema syndrome (BMES). This study aimed to map the diversity and frequency of diagnostic terms and vocabulary utilized in the literature. A comprehensive search of electronic databases and reference lists was conducted. Publications that reported on patients with TOH, RMO, BMES, or related variants were eligible for inclusion. The terminologies were categorized based on the wording of the titles, abstracts, or texts. We included 561 publications, of which 423 were case reports, involving 2921 patients. Overall, TOH was the most commonly used term, occurring in 257 (45.8%). RMO was used in 34 (6.1%) and BMES in 57 (10.2%). The remaining used various combinations of transient, migratory, and regional in conjunction with either osteoporosis or bone marrow edema. Localized osteoporosis was not used. We identified three different terms related to pregnancy. In 76.3% of the publications, the terminology was related to osteoporosis and in 18.2% to bone marrow edema, although terminology did not correspond to actual findings. Bone marrow edema occurred as often as osteoporosis, and osteoporosis was generally ascertained by visual inspection of radiographs, seldom by bone densitometry. Many publications used osteoporosis-related terms without evidence that osteoporosis had been detected. The terminology of these closely related entities is confusing and unstandardized. The lack of formal definitions impedes accurate diagnosis, research on disease mechanisms, and effective treatment.

[Translated article] Reticulate Skin Lesions: Practical Color-Based Algorithm for Initial Clinical Assessment

Reticular patterns are observed in a great variety of skin diseases. While these morphologic patterns are often highly distinctive, they are seldom discussed or studied in clinical contexts or recognized as a diagnostic category in their own right. Diseases presenting with reticulate skin lesions have multiple etiologies (tumors, infections, vascular disorders, inflammatory conditions, and metabolic or genetic alterations) and can range from relatively benign conditions to life-threatening ones. We review a selection of these diseases and propose a clinical diagnostic algorithm based on predominant coloring and clinical features to aid in their initial assessment.

Protective Effect of Chrysin against Chlorpyrifos-Induced Metabolic Impairment and Pancreatitis in Male Rats

BACKGROUND

This study was performed to evaluate the protective effects of chrysin (CH) on metabolic impairment and pancreatic injury caused by sub-chronic chlorpyrifos (CPF) intoxication in male rats.

METHODS

Forty male Wistar rats were randomly allocated into five groups (n=8). Intraperitoneal injections of chrysin (12.5, 25 and 50 mg/kg for 45 days) and CPF (10 mg/kg for 45 days) gavage were performed. Present findings indicated that the serum levels of glucose, total cholesterol, and lowdensity lipoprotein-cholesterol, as well as body weight, were increased in the CPF-exposed group.

RESULTS

It was also found that CPF decreased superoxide dismutase activity as well as increased malondialdehyde and nitric oxide levels in the pancreatic tissue of exposed animals. Histopathological examination also confirmed the toxic effects of CPF on pancreatic tissue as mostly evidenced by infiltration of inflammatory cells and necrosis. CH (50 mg/kg) decreased blood glucose concentration (p < 0.05), TG (p < 0.05), and LDL-C in CPF-exposed animals. CH decreased the pancreas levels of MDA in all treated CPF-exposed groups versus the non-treated CPF-exposed group (p < 0.05, p < 0.001, p < 0.001, respectively). A significant difference was not seen in the NO and MDA levels and SOD activity between CH-treated (50 mg/kg) animals exposed to CPF and controls. A significant difference was not seen in the NO and MDA levels and SOD activity between CHtreated (50 mg/kg) animals exposed to CPF and controls.

CONCLUSION

A significant difference was not seen in the NO and MDA levels and SOD activity between CH-treated (50 mg/kg) animals exposed to CPF and controls. In conclusion, CH could prevent initiate and progress of CPF-induced metabolic impairment by modulating oxidative stress in pancreatic tissue as a target organ of organophosphorus pesticides.

METABOLIC SYNDROME AND ASSOCIATED RISK FACTORS AMONG SECONDARY SCHOOL ADOLESCENTS IN NORTHEAST NIGERIA

Introduction

Metabolic syndrome (MetS) is a cluster of risk factors that may predispose to cardiovascular diseases and type 2 diabetes mellitus. These risk factors include hypertension, central obesity, hyperglycaemia, hypertriglyceridemia and low high-density lipoprotein cholesterol (HDL-C). The presence of at least three of these risks factors defines MetS. Globally, MetS now affects children and adolescents with increasing obesity prevalence. This study determined the prevalence of MetS and associated risk factors among secondary school adolescents in Gombe Local Government Area(LGA), Northeast Nigeria.

Methods

A cross-sectional study; 688 participants from 12 secondary schools in Gombe LGA, Northeast Nigeria. Data were obtained using structured questionnaire. Anthropometry and blood pressure were measured. Fasting plasma glucose, serum triglyceride and HDL-C were determined. Data were analysed using SPSS version 21.

Result

The prevalence of MetS was 1.3%. Low serum HDL-C was the commonest risk factor. MetS was significantly higher in upper socio-economic class and private school participants. Lifestyle and family medical history were not significantly associated with MetS.

Conclusion

This study showed that the prevalence of metabolic syndrome was low in the overall study population but high among centrally obese adolescents. Metabolic syndrome occurred in normal weight and underweight participants. Low HDL-C was the commonest risk factor for metabolic syndrome and lifestyle and family medical history were not associated with metabolic syndrome.

Comprehensive Preventive and Therapeutic Oral Health Care: A Case Report of Mucopolysaccharidosis Type IV A in a Pediatric Patient

Mucopolysaccharidosis (MPS) is a metabolic disorder resulting from a deficiency of lysosomal enzymes. It is an autosomal recessive disorder with similar incidences in men and women. Mucopolysaccharidosis type IV A is caused by a deficiency of N-acetylgalactosamine-6-sulfatase, which deficiency is, in turn, caused by alterations in the GALNS gene. It is marked by a short stature, a pigeon chest, frontal bossing, kyphosis, and a flat nasal bridge. Intraorally, macroglossia, hypodontia, dentinogenesis imperfecta, a broad mouth, and an anterior open bite are some of the common features. The present paper reports on a case of MPS in a 5-year-old male patient, along with providing a review of the literature and insight into the oral manifestations related to MPS IV A, also called Morquio A syndrome, and its dental treatment. It aims to highlight the clinical recommendations for oral health care in such cases during different phases of MPS IV A treatment.

Frailty Screening and Detection of Geriatric Syndromes in Acute Inpatient Care: Impact on Hospital Length of Stay and 30-Day Readmissions

BACKGROUND

Frailty is prevalent in acute care and is associated with negative outcomes. While a comprehensive geriatric assessment to identify geriatric syndromes is recommended after identifying frailty, more evidence is needed to support this approach in the inpatient setting. This study examined the association between frailty and geriatric syndromes and their impact on outcomes in acutely admitted older adults.

METHODS

A total of 733 individuals aged ≥65 years admitted to the General Surgery Service of a tertiary hospital were assessed for frailty using the Clinical Frailty Scale (CFS) and for geriatric syndromes using routine nursing admission assessments, including cognitive impairment, falls, incontinence, malnutrition, and poor oral health. Multinomial logistic regression and Cox regression were used to evaluate the associations between frailty and geriatric syndromes and their concomitant impact on hospital length of stay (LOS) and 30-day readmissions.

RESULTS

Greater frailty severity was associated with an increased likelihood of geriatric syndromes. Individuals categorized as CFS 4-6 and CFS 7-8 with concomitant geriatric syndromes had 29% and 35% increased risks of a longer LOS, respectively. CFS 4-6 was significantly associated with functional decline (relative risk ratio =1.46; 95% confidence interval [CI], 1.03-2.07) and 30-day readmission (hazare ratio=1.78; 95% CI, 1.04-3.04), whereas these associations were not significant for CFS 7-8.

CONCLUSION

Geriatric syndromes in frail individuals can be identified from routine nursing assessments and represent a potential approach for targeted interventions following frailty identification. Tailored interventions may be necessary to achieve optimal outcomes at different stages of frailty. Further research is required to evaluate interventions for older adults with frailty in a wider hospital context.

Investigation of (Epi)genetic causes in syndromic short children born small for gestational age

Intrauterine onset syndromic short stature constitutes a group of diseases that pose challenges in differential diagnosis due to their rarity and clinical as well as molecular heterogeneity. The aim of this study was to investigate the presence of (epi)genetic causes in children born small for gestational age (SGA) and manifesting clinically undiagnosed syndromic short stature. The study group comprised twenty-nine cases selected from the syndromic SGA cohort. Various analyses were performed, including chromosomal microarray (CMA), methylation-specific-multiple ligation probe amplification for chromosomes 6,14 and 20, and whole exome sequencing (WES). Pathogenic copy number variants (CNVs) on chromosomes 2q13, 22q11.3, Xp22.33, 17q21.31, 19p13.13 and 4p16.31 causing syndromic growth disturbance were detected in six patients. Maternal uniparental disomy 14 was identified in a patient. WES was performed in the remaining 22 patients, revealing pathogenic variants in nine cases; six were monoallelic (ACAN, ARID2, NIPBL, PIK3R1, SMAD4, BRIP1), two were biallelic (BRCA2, RFWD3) and one was hemizygous (HUWE1). Seven of these were novel. Craniofacial dysmorphism, which is an important clue for the diagnosis of syndromes, was very mild in all patients. This study unveiled, for the first time, that ARID2 mutatios can cause syndromic SGA. In conclusion, a high (55.2%) diagnosis rate was achieved through the utilization of CMA, epigenetic and WES analyzes; 15 rare syndromes were defined, who were born with SGA and had atypical and/or mild dysmorphic findings. This study not only drew attention to the association of some rare syndromes with SGA, but also introduced novel genes and CNVs as potential contributors to syndromic SGA.

Whole genome sequencing and disease pattern in patients with juvenile polyposis syndrome: a nationwide study

Juvenile polyposis syndrome (JPS) is a hereditary hamartomatous polyposis syndrome characterized by gastrointestinal juvenile polyps and increased risk of gastrointestinal cancer. Germline pathogenic variants are detected in SMAD4 or BMPR1A, however in a significant number of patients with JPS, the etiology is unknown. From Danish registers, and genetic department and laboratories, we identified all patients in Denmark with a clinical diagnosis of JPS and/or a pathogenic variant in BMPR1A or SMAD4. In patients where no variant had been detected, we performed genetic analysis, including whole genome sequencing. We collected clinical information on all patients to investigate the phenotypic spectrum. Sixty-six patients (mean age 40 years) were included of whom the pathogenic variant was unknown in seven patients. We detected a pathogenic variant in SMAD4 or PTEN in additional three patients and thus ≈ 95% of patients had a pathogenic germline variant. Endoscopic information was available in fifty-two patients (79%) and of these 31 (60%) fulfilled the clinical criteria of JPS. In 41 patients (79%), other types of polyps than juvenile had been removed. Our results suggest that almost all patients with a clinical diagnosis of JPS has a pathogenic variant in mainly BMPR1A, SMAD4, and more rarely PTEN. However, not all patients with a pathogenic variant fulfil the clinical criteria of JPS. We also demonstrated a wide clinical spectrum, and that the histopathology of removed polyps varied.

Pediatric head and neck manifestations associated with multiple endocrine neoplasia syndromes

INTRODUCTION

Multiple endocrine neoplasia (MEN) syndromes are a group of hereditary cancer syndromes that can predispose children to endocrine neoplasms developing within the head and neck.

OBJECTIVE

To examine the neoplastic manifestations of MEN type 1 (MEN1) and MEN type 2 (MEN2) in the pediatric head and neck.

METHODS

Single-institution, retrospective review of pediatric MEN between 2005 and 2022.

RESULTS

Fifty-three children were genetically confirmed with MEN (15 MEN1, 34 MEN2A, and 4 MEN2B), while three patients received clinical diagnoses of MEN1. The male to female ratio was essentially equal (1.15:1), and a documented family history of cancer was present in 89% (50/56). After multidisciplinary evaluation, a familial MEN diagnosis was confirmed in 91% (51/56). The mean ages of initial presentation and surgical intervention were 8.9 years (SD 5) and 9.8 years (SD 4.8), respectively. Although patients with MEN2 received surgery earlier than patients with MEN1 (8.7 vs 12.7 years), surgical patients with MEN2 in this cohort were older relative to current American Thyroid Association (ATA) guidelines primarily due to late presentation. Thyroid malignancies were identified in 36% (9/25) of thyroidectomy specimens (21 MEN2A, 4 MEN2B), with medullary thyroid carcinoma (MTC) present in five MEN2A patients and three MEN2B patients (89%), and papillary thyroid carcinoma (PTC) present in one MEN2A patient (11%). Nearly 90% (8/9) of thyroid malignancies were occult, with some occurring earlier than predicted by current guidelines (ATA-MOD and ATA-H). Central neck dissections were performed in 24% (2 MEN1, 2 MEN2A, and 4 MEN2B), with two MEN2B (50%) demonstrating cervical lymph node (LN) metastases. Additional histopathologic findings included C-cell hyperplasia in 57% (12/21) of MEN2A thyroidectomy patients. Of the eight MEN1 parathyroidectomy patients, four demonstrated parathyroid hyperplasia and four presented with parathyroid adenoma.

CONCLUSION

Nearly 60% required head and neck procedures. While MEN1 guidelines were appropriate for our cohort, we identified patients with MEN2 that developed MTC earlier than expected based on current ATA guidelines, including children in categories considered lower risk. In conjunction with a multidisciplinary approach, pediatric head and neck surgeons should be aware of the potential need for earlier surgical intervention in the pediatric MEN2 population.

Making the Improbable Possible: Generalizing Models Designed for a Syndrome-Based, Heterogeneous Patient Landscape

Syndromic conditions, such as sepsis, are commonly encountered in the intensive care unit. Although these conditions are easy for clinicians to grasp, these conditions may limit the performance of machine-learning algorithms. Individual hospital practice patterns may limit external generalizability. Data missingness is another barrier to optimal algorithm performance and various strategies exist to mitigate this. Recent advances in data science, such as transfer learning, conformal prediction, and continual learning, may improve generalizability of machine-learning algorithms in critically ill patients. Randomized trials with these approaches are indicated to demonstrate improvements in patient-centered outcomes at this point.

Miller Fischer syndrome after COVID-19 infection and vaccine: a systematic review

BACKGROUND

COVID-19 (CoranaVirus disease 2019) is an ongoing infectious disease caused by the RNA SARS-CoV-2 virus (Severe Acute Respiratory Syndrome CoronaVirus-2). The virus mainly causes respiratory symptoms, but neurological symptoms have also been reported to be part of the clinical manifestations of the disease. The aim of this study was to systematically review Miller fisher syndrome (MFS) published cases, in the context of COVID-19 infection or vaccination.

METHODS

A systematic literature review on Medline was performed. A total of 21 papers were included in the present review.

RESULTS

Twenty-two MFS cases (77% males) were identified, 14 related to COVID-19 infection and 8 to vaccination against COVID-19. The median age of the adult patients was 50 years (interquartile range 36-63 years). Sixteen patients (73%) had the classic triad of MFS (ophthalmoplegia, ataxia, areflexia), four (18%) had acute ophthalmoplegia and one other characteristic symptom and two patients (9%) had only one other characteristic symptom, but they tested positive for GQ1b antibodies. Nine (41%) patients had positive GQ1b antibodies and were classified as "definite" MFS. Albuminocytologic dissociation was found in half of the cases. The outcome was favourable in the majority of cases (86%) whereas one patient, despite the initial improvement, died because of a cardiac arrest, after cardiac arrythmia.

CONCLUSIONS

MFS after COVID-19 infection/vaccination was found to have the typical epidemiological characteristics of classic MFS; being rare, occurring more often after infection than vaccination, affecting mainly middle-aged males usually within 3 weeks after the event and having an excellent prognosis after treatment with IVIG or even with no treatment at all. We found no evidence that MFS after COVID-19 infection was different from MFS after COVID-19 vaccination, although the former tended to occur earlier.

Auricular fistula: a review of its clinical manifestations, genetics, and treatments

Auricular fistula is a common congenital auricular malformation, characterized as a small opening in the skin and a subcutaneous cyst. It can be classified in different ways according to positions of pits and directions of fistula tracts. The term preauricular fistula and variant type of preauricular fistula (postauricular fistula) are used. Auricular fistula prevalence varies in countries and populations, and its actual prevalence is presently unknown. The most accepted and widely cited theory of auricular fistula etiopathogenesis is an incorrect or incomplete fusion of six auricular hillocks that are mesenchymal proliferations. Auricular fistula can occur either sporadically or genetically. The pattern in inherited cases is thought to be incomplete autosomal dominant, with variable expressions, reduced penetrance, and inapparent gender differences. Auricular fistula has several forms and is reported as being a component of many syndromes. In the field of genetics, currently, there is no related review to comprehensively summarize the genetic basis of auricular fistula and related disorders. This article provides a comprehensive review of auricular fistula, especially congenital preauricular fistula, which accounts for the majority of auricular fistula, by summarizing the clinical manifestations, histological and embryological development, genetics, examinations, and treatments, as well as syndromes with auricular fistula.

Management and follow-up of uveal effusion syndrome: a case report

BACKGROUND

We present the management and follow-up of a case of uveal effusion syndrome (UES).

CASE PRESENTATION

We study the relevant recent literature reports and review the aetiology, clinical classification, pathogenesis, diagnostic characteristics, treatment methods, and prognosis of this disease. When we encounter UES patients clinically, we can classify them according to their clinical characteristics and adopt different treatment plans for different types. The retina of this patient reattached 5 months after receiving eight periocular injections of triamcinolone acetonide (TA).

CONCLUSIONS

For type III UES patients, local hormone therapy can be applied, and follow-up should be done to optimize the clinical outcome.

Metabolic syndrome and the likelihood of knee pain and functional disability: evidence from a large middle eastern population-based study

OBJECTIVES

Metabolic Syndrome (MetS) has been associated with knee osteoarthritis (KOA) in animal studies, but epidemiologic evidence of the association remains controversial. We investigated the association between MetS and knee pain and functional disability, the hallmarks of KOA, in a Middle Eastern population with high reported MetS rates.

METHODS

A population-based study of adult individuals was conducted between 01/2016 and 03/2019. Data collected included age, sex, blood pressure, body mass index (BMI), waist circumference (WC), and comprehensive metabolic panel blood tests. Knee symptoms were assessed using The Western Ontario and McMaster Arthritis index (WOMAC) The Adult Treatment Panel III criteria was applied to determine if participants had MetS. Multivariable regression was used to determine the association of MetS, and its components, with the WOMAC total and subscale scores.

RESULTS

Of 6,000 participants enrolled, 15.5% had MetS. The multivariate regression demonstrated that participants with MetS had significantly higher WOMAC total and subscale scores after adjusting for demographic variables; however, these associations were not significant after adjusting for BMI. Multivariate regression examining the association between MetS components and the WOMAC scores showed sex-based significant differences with WOMAC scores; however, the differences were not larger than the minimally clinical important differences.

CONCLUSIONS

This study demonstrated that after adjustment for BMI, neither MetS nor its individual parameters were associated with worse knee symptoms. As such, the association between MetS and worse knee symptoms requires further study.

A Missense Pathogenic Variant in a Conserved Region of CNTNAP2 Is Associated with Obesity, Seizures, and Language Impairment in a Pakistani Family

Introduction

In a consanguineous family, seven siblings born in three sibships showed a syndromic disorder characterized by obesity, seizures, and language impairment phenotypes, which appeared at early age or developed during early childhood.

Methods

By whole-exome sequencing and subsequent Sanger sequencing, a novel homozygous missense variant (c.3371 T>A [p.Ile1124Asn]) in exon 20 of the CNTNAP2 gene was identified.

Results

The pathogenic variant in this family is located within one of the laminin G-like 4 domains of CASPR2 and may cause loss of hydrophobic interactions of CASPR2 with its partner proteins. Single nucleotide and copy number variants in this gene have previously been related to Gilles de la Tourette syndrome, cortical dysplasia-focal epilepsy syndrome, schizophrenia, Pitt-Hopkins syndrome, and autism spectrum, attention deficit hyperactivity, and obsessive compulsive disorders. Yet, few studies described patients with CNTNAP2 variants showing diet-induced obesity.

Conclusion

This report expands the phenotypic spectrum of this rare syndrome and provides deeper insights by documenting the clinical features and genetic findings of the patients.

Severity classification and influencing variables of the Postintensive Care Syndrome

OBJECTIVE

The study aims to characterise Postintensive Care Syndrome by classifying the severity of the disease and identifying the variables of influence in two highly complex intensive care units for adults in Colombia.

METHODS

A descriptive, cross-sectional, prospective study was carried out to characterise survivors of critical illness using the Healthy Aging Brain Care -Monitor in a sample of 135 patients. Postintensive Care Syndrome severity was classified using Gaussian Mixture Models for clustering, and the most influencing variables were identified through ordinal logistic regression.

RESULTS

Clustering based on Gaussian Mixture Models allowed the classification of Postintensive Care Syndrome severity into mild, moderate, and severe classes, with an Akaike Information Criterion of 308 and an area under the curve of 0.80, which indicates a good fit; Thus, the mild class was characterised by a score on the HABC-M Total scale ≤9; the moderate class for a HABC-M Total score ≥10 and ≤42 and the severe class for a HABC-M Total score ≥43. Regarding the most influencing variables, the probability of belonging to the moderate or severe classes was related to male sex (91%), APACHE II score (22.5%), age (13%), intensive care units days of stay (10.6%), the use of sedation, analgesia and neuromuscular blockers.

CONCLUSION

Intensive care units survivors were characterised using the Healthy Aging Brain Care-Monitor scale, which made it possible to classify Postintensive Care Syndrome through Gaussian Mixture Models clustering into mild, moderate, and severe and to identify variables that had the major influence on the presentation of Postintensive Care Syndrome.

The neuroanatomical hallmarks of chronic tinnitus in comorbidity with pure-tone hearing loss

Tinnitus is one of the main hearing impairments often associated with pure-tone hearing loss, and typically manifested in the perception of phantom sounds. Nevertheless, tinnitus has traditionally been studied in isolation without necessarily considering auditory ghosting and hearing loss as part of the same syndrome. Hence, in the present neuroanatomical study, we attempted to pave the way toward a better understanding of the tinnitus syndrome, and compared two groups of almost perfectly matched individuals with (TIHL) and without (NTHL) pure-tone tinnitus, but both characterized by pure-tone hearing loss. The two groups were homogenized in terms of sample size, age, gender, handedness, education, and hearing loss. Furthermore, since the assessment of pure-tone hearing thresholds alone is not sufficient to describe the full spectrum of hearing abilities, the two groups were also harmonized for supra-threshold hearing estimates which were collected using temporal compression, frequency selectivity und speech-in-noise tasks. Regions-of-interest (ROI) analyses based on key brain structures identified in previous neuroimaging studies showed that the TIHL group exhibited increased cortical volume (CV) and surface area (CSA) of the right supramarginal gyrus and posterior planum temporale (PT) as well as CSA of the left middle-anterior part of the superior temporal sulcus (STS). The TIHL group also demonstrated larger volumes of the left amygdala and of the left head and body of the hippocampus. Notably, vertex-wise multiple linear regression analyses additionally brought to light that CSA of a specific cluster, which was located in the left middle-anterior part of the STS and overlapped with the one found to be significant in the between-group analyses, was positively associated with tinnitus distress level. Furthermore, distress also positively correlated with CSA of gray matter vertices in the right dorsal prefrontal cortex and the right posterior STS, whereas tinnitus duration was positively associated with CSA and CV of the right angular gyrus (AG) and posterior part of the STS. These results provide new insights into the critical gray matter architecture of the tinnitus syndrome matrix responsible for the emergence, maintenance and distress of auditory phantom sensations.

Diagnosis Support for Rare Diseases Using Phenotypic Profiles

The common occurrence of characteristic symptoms can be used to infer diagnoses. The aim of this study is to show how syndrome similarity analysis using given phenotypic profiles can help in the diagnosis of rare diseases. HPO was used to map syndromes and phenotypic profiles. The system architecture described is planned to be implemented in a clinical decision support system for unclear diseases.

Acute Budd-Chiari Syndrome with Complete Portal Vein Thrombosis Complicated by Hepato-Renal Syndrome Treated Successfully by Emergent TIPS with Rheolytic Thrombectomy

We described a case of a 73-year-old female admitted to the emergency department with acute hepatic and renal failure (hepato-renal syndrome, HRS) due to acute Budd-Chiari syndrome associated with complete portal vein thrombosis (BCS-PVT) for an unknown cause. Despite the initial therapy with anticoagulants, a sudden impairment of the renal function requiring hemodialysis was observed. The hepatic transplant was excluded for patient age and clinical conditions. Thus, the patient was successfully treated by emergent transjugular intrahepatic portosystemic shunt (TIPS) previous rheolytic thrombectomy of the PVT with AngioJet Ultra PE Thrombectomy System (Boston Scientific, Marlborough, MA, USA). After the procedure, the sudden resolution of the HRS was observed, and the patient is alive 13 months after hospital dismission with no TIPS dysfunction. In conclusion, emergent extended TIPS with the usage of rheolytic thrombectomy device in patient with acute BCS-PVT complicated by HRS is feasible by experienced operators and provide resolution of the HRS.

When should clinicians use the term syndrome?

Medical language provides essential communication with patients and among healthcare providers. Some words appear frequently in this communication, in clinical records, and in the medical literature, and the use of these words assumes that the listener and reader understand their meaning in the context related to their current use. Words, such as syndrome, disorder, and disease, should have obvious definitions but often, in fact, have uncertain meanings. In particular, the word syndrome should imply a definite and stable association between patient characteristics that have implications for treatment, prognosis, pathogenesis, and possibly clinical studies. In many cases the strength of this association is uncertain and the use of the word represents a convenient shorthand which may or may not improve communication with patients or other clinicians. Some astute clinicians have identified associations in their clinical practices, but this is a slow haphazard process. The development of electronic medical records, internet-based communication, and advanced statistical techniques has the potential to clarify important features of syndromes. However, the recent analysis of certain subsets of patients in the ongoing COVID-19 pandemic has demonstrated that even large amounts of information and advanced statistical techniques using clustering or machine learning may not provide precise separation of patients into groups. Clinicians should use the word syndrome carefully.

Ten-year survival of children with trisomy 13 or trisomy 18: a multi-registry European cohort study

OBJECTIVE

To investigate the survival to 10 years of age of children with trisomy 13 (T13) and children with trisomy 18 (T18), born 1995-2014.

DESIGN

Population-based cohort study that linked mortality data to data on children born with T13 or T18, including translocations and mosaicisms, from 13 member registries of EUROCAT, a European network for the surveillance of congenital anomalies.

SETTING

13 regions in nine Western European countries.

PATIENTS

252 live births with T13 and 602 with T18.

MAIN OUTCOME MEASURES

Survival at 1 week, 4 weeks and 1, 5 and 10 years of age estimated by random-effects meta-analyses of registry-specific Kaplan-Meier survival estimates.

RESULTS

Survival estimates of children with T13 were 34% (95% CI 26% to 46%), 17% (95% CI 11% to 29%) and 11% (95% CI 6% to 18%) at 4 weeks, 1 and 10 years, respectively. The corresponding survival estimates were 38% (95% CI 31% to 45%), 13% (95% CI 10% to 17%) and 8% (95% CI 5% to 13%) for children with T18. The 10-year survival conditional on surviving to 4 weeks was 32% (95% CI 23% to 41%) and 21% (95% CI 15% to 28%) for children with T13 and T18, respectively.

CONCLUSIONS

This multi-registry European study found that despite extremely high neonatal mortality in children with T13 and T18, 32% and 21%, respectively, of those who survived to 4 weeks were likely to survive to age 10 years. These reliable survival estimates are useful to inform counselling of parents after prenatal diagnosis.

Open aortic septectomy for complicated type B aortic dissection

Malperfusion is a complication of acute aortic dissection associated with substantially increased morbidity and mortality. Although endovascular treatment of the dissection with a stent graft to cover the intimal tear and reexpand the true lumen will often be sufficient to treat distal malperfusion, persistent or delayed malperfusion will necessitate additional interventions. Endovascular strategies to increase true lumen expansion include bare metal dissection stent placement and percutaneous fenestration. However, for patients with anatomy not amenable to an endovascular approach, alternative techniques are required. We describe two cases of complicated acute aortic dissection due to partial false lumen thrombosis treated with open aortic septectomy. Although an uncommon procedure, open septectomy can be useful for patients with malperfusion syndromes without appropriate endovascular options.

Syndromes associated with Robin sequence: a national prospective cohort study

OBJECTIVES

To determine the prevalence of syndromic Robin sequence (RS) in the UK and if this group of patients had an increased need for airway and feeding management compared with a non-syndromic RS cohort.

DESIGN

A prospective national multicentre study of cases submitted to the Cleft Collective cohort studies.

SETTING

Specialist cleft services in the UK.

PATIENTS

259 participants who fulfilled the diagnosis of RS. This group was compared with 548 participants with cleft palate only (CPO).

MAIN OUTCOME MEASURES

The primary outcome measure was the presence of a syndrome in patients with RS and CPO. Secondary outcome measures included the use of airway and feeding adjuncts.

RESULTS

An associated syndrome was seen in 28% of patients with RS and 14% of patients with CPO. The most common syndrome for the RS group was Stickler syndrome (27%). Syndromic status was significantly higher among patients with RS compared with those with CPO (OR 2.36, 95% CI 1.65 to 3.39; p<0.001). Patients with syndromic RS have an increased reliance on airway adjuncts compared with the patients without syndromic RS (OR 2.02, 95% CI 1.13 to 3.64; p=0.018). There was no evidence of a difference in the use of feeding adjuncts between syndromic and non-syndromic RS groups (OR 2.43, 95% CI 0.78 to 7.58; p=0.126).

CONCLUSION

The presence of a syndrome has implications for management of patients with RS. Early identification of a syndrome may help prevent the consequences of a missed syndromic diagnosis. Routine ophthalmological and genetic screening for Stickler syndrome should be mandatory for all patients with RS.

A Prospective, Randomized Trial Examining the Use of G-CSF Versus No G-CSF in Patients Post-Autologous Transplantation

Contemporary, prospective data regarding the impact of granulocyte-colony stimulating factor (G-CSF) on outcomes after autologous hematopoietic stem cell transplantation (Auto-HSCT) in an era when stem cell grafts are more qualitatively robust are limited. Recent retrospective analyses have not supported a beneficial effect of post-transplantation G-CSF use on major outcomes after Auto-HSCT leading to strategies to delay or eliminate the use of G-CSF altogether in this context. To test the hypothesis that the infusion of consistently higher doses of stem cells (defined as ≥4 × 10⁶/kg) in Auto-HSCT will obviate the need for post-transplantation G-CSF. If so, the impact of withholding G-CSF will be noninferior to the use of G-CSF in terms of length of stay (LOS). The specific objectives were to conduct a prospective, randomized clinical trial primarily examining the impact of post-transplantation G-CSF on LOS, and secondarily on engraftment, infectious complications, antibiotic usage, and incidence of engraftment syndrome after Auto-HSCT in patients receiving versus not receiving G-CSF after Auto-HSCT. Patients with multiple myeloma or non-Hodgkin lymphoma (NHL) who underwent Pegfilgrastim plus Plerixafor-primed stem cell collection followed by Auto-HSCT were randomized to the G-CSF group (receive G-CSF starting at day 3 after Auto-HSCT) or the no G-CSF group (G-CSF withheld after Auto-HSCT). Seventy patients per arm were planned to demonstrate the primary endpoint of noninferiority in LOS between the G-CSF and the no G-CSF groups. Patient outcomes in the two groups were followed up and compared after Auto-HSCT, and an interim analysis for futility was planned when accrual reached 50%.The primary finding of this study was that despite only a 2-day longer median absolute neutrophil count (ANC) recovery in the no G-CSF arm (median 11 versus 13 days; P = .001), LOS was 4 days longer in patients not treated with G-CSF (median 11 days versus 15 days; P = .001). G-CSF use was associated with more robust incremental daily increases in ANC once recovered (P = .001), fewer days of febrile neutropenia (P = .001), and fewer days on antibiotics (P = .001), potentially contributing to this disproportionate finding. Inferiority in LOS in the no G-CSF group was demonstrated on the interim analysis, and the study was closed at the half-way point. There were no significant group differences in platelet recovery, documented infections, hospital readmissions, or overall survival at 1 year. Engraftment syndrome occurred in 54.3% of patients and was not related to G-CSF use. These results suggest that the increased LOS associated with the omission of G-CSF is largely due to concerns regarding the potential for infection in patients without a stable, recovered ANC in a hospital setting. Engraftment syndrome represented a significant source of febrile neutropenia further contributing to patient safety concerns and requires strategies to decrease its incidence. Infectious complications and death were not affected by the omission of G-CSF supporting a carefully monitored outpatient approach to Auto-HSCT in which white blood cell growth factor is eliminated or given as needed for documented infection. © 2023 American Society for Blood and Marrow Transplantation.

A case of prune belly syndrome: Experience from a regional hospital in Togo

INTRODUCTION AND IMPORTANCE

Prune Belly syndrome is a rare congenital condition first reported in 1939. It is a malformative disease associated with high mortality. We report a neonatal case in a regional hospital in Togo.

PRESENTATION OF CASE

A 4-month-old male infant was brought to the hospital by his uncle because of a "deformity of the abdomen and absence of testicles". The examination revealed hypoplasia of the abdominal wall associated with bilateral cryptorchidism. Abdominal and urinary tract ultrasound revealed a left pyelocaliceal dilatation and a right megaureter. All these data allowed the diagnosis of Prune Belly syndrome.

CONCLUSION

Prune Belly syndrome is a rare and complex disease with a high mortality rate.

Establishing breast feeding in infants with Down syndrome: the FADES cohort experience

OBJECTIVE

To describe breastfeeding prevalence and maternal experience in infants with trisomy 21.

DESIGN

Longitudinal cohort study.

SETTING

Participants from UK recruited through websites, social media and local collaborators: neonatologists, community paediatricians and research nurses.

SUBJECTS

Infants under the age of 8 months with Down syndrome (DS) recruited to the Feeding and Autoimmunity in Down Syndrome Evaluation Study between 1 September 2014 and 31 August 2017. Seventy participants: median age 20 weeks (IQR 13-29 weeks) at initial questionnaire.

MAIN OUTCOME MEASURE

Breastfeeding prevalence at 6 weeks and 6 months among infants with DS.

RESULTS

The prevalence of exclusive breast feeding among study participants was similar to the general population (13/61, 21% vs 23% at 6 weeks, 2/54, 4% vs 1% at 6 months). However, the prevalence of breast feeding (exclusive or combination feeding) among the study participants was higher than the general population (39/61 64% vs 55% at 6 weeks, 32/59 54% vs 34% at 6 months).

CONCLUSION

Although there may be challenges in establishing breast feeding in infants with DS, our data suggest that exclusive breast feeding is possible for some, and the prevalence of breast feeding is comparable to the prevalence in the general population.

Cri du chat syndrome patients have DNA methylation changes in genes linked to symptoms of the disease

Background

Cri du chat (also called 5p deletion, or monosomy 5p) syndrome is a genetic disease caused by deletions of various lengths in the short (p) arm of chromosome 5. Genetic analysis and phenotyping have been used to suggest dose-sensitive genes in this region that may cause symptoms when a gene copy is lost, but the heterogeneity of symptoms for patients with similar deletions complicates the picture. The epigenetics of the syndrome has only recently been looked at with DNA methylation measurements of blood from a single patient, suggesting epigenetic changes in these patients. Here, we conduct the deepest epigenetic analysis of the syndrome to date with DNA methylation analysis of eight Cri du chat patients with sibling- and age-matched controls.

Results

The genome-wide patterns of DNA methylation in the blood of Cri du chat patients reveal distinct changes compared to controls. In the p-arm of chromosome 5 where patients are hemizygous, we find stronger changes in methylation of CpG sites than what is seen in the rest of the genome, but this effect is less pronounced in gene regulatory sequences. Gene set enrichment analysis using patient DNA methylation changes in gene promoters revealed enrichment of genes controlling embryonic development and genes linked to symptoms which are among the most common symptoms of Cri du chat syndrome: developmental delay and microcephaly. Importantly, this relative enrichment is not driven by changes in the methylation of genes on chromosome 5. CpG sites linked to these symptoms where Cri du chat patients have strong DNA methylation changes are enriched for binding of the polycomb EZH2 complex, H3K27me3, and H3K4me2, indicating changes to bivalent promoters, known to be central to embryonic developmental processes.

Conclusions

Finding DNA methylation changes in the blood of Cri du chat patients linked to the most common symptoms of the syndrome is suggestive of epigenetic changes early in embryonic development that may be contributing to the development of symptoms. However, with the present data we cannot conclude about the sequence of events between DNA methylation changes and other cellular functions—the observed differences could be directly driving epigenetic changes, a result of other epigenetic changes, or they could be a reflection of other gene regulatory changes such as changed gene expression levels. We do not know which gene(s) on the p-arm of chromosome 5 that causes epigenetic changes when hemizygous, but an important contribution from this work is making the pool of possible causative genes smaller.

Proteus Syndrome: Case Report with Anatomopathological Correlation

Background: Proteus syndrome is characterized by a progressive segmental or patchy growth of bone, skin, adipose tissue, and central nervous system, associated with a wide range of neoplasms, pulmonary pathology, and thrombotic risk. The main histological findings are diffuse patchy overgrowth of skin and subcutaneous tissue, plantar cerebriform connective tissue nevus, and ossification defects. Case report: We present a patient that met the clinical and histological criteria necessary for the diagnosis of the disease. He required multiple surgical interventions, including amputation of the right foot. Genetic evaluation confirmed an AKT1 mutation. Discussion: CLOVES syndrome, neurofibromatosis 1 or PTEN hamartoma tumor syndrome are partially superimposable entities to Proteus syndrome and may generate diagnostic doubt. Although the clinical criteria and histologic findings are indicative, the diagnostic confirmation of this entity is genetic.

Cannabinoid hyperemesis syndrome and cannabis withdrawal syndrome: a review of the management of cannabis-related syndrome in the emergency department

Background

Cannabis-related medical consultations are increasing worldwide, a non-negligible public health issue; patients presenting to acute care traditionally complain of abdominal pain and vomiting. Often recurrent, these frequent consultations add to the congestion of already chronically saturated emergency department(s) (ED). In order to curb this phenomenon, a specific approach for these patients is key, to enable appropriate treatment and long-term follow-up.

Objectives

This study reviews cannabinoid hyperemesis syndrome (CHS) and cannabis withdrawal syndrome (CWS), in a bid to help promote better understanding and handling of pathologies associated with chronic cannabis use. Following a literature review, we present a novel therapeutic algorithm aimed at guiding clinicians, in a bid to improve long-term outcomes and prevent recurrences.

Methods

Using the keywords “Cannabis,” “Hyperemesis,” “Syndrome,” “Withdrawal,” and “Emergency Medicine,” we completed a literature review of three different electronic databases (PubMed®, Google scholar®, and Cochrane®), up to November 2021.

Results

Although often presenting with similar symptoms such as abdominal pain and vomiting, cannabinoid hyperemesis syndrome (CHS) and cannabis withdrawal syndrome (CWS) are the result of two differing pathophysiological processes. Distinguishing between these two syndromes is essential to provide appropriate symptomatic options.

Conclusion

The correct identification of the underlying cannabis-related syndrome, and subsequent therapeutic choice, may help decrease ED presentations. Our study emphasizes the importance of both acute care and long-term outpatient follow-up, as key processes in cannabis-related disorder treatment.

Syndromes associated with sexually transmitted infections: Prevalence and risk factors among women of childbearing age in Morocco

This research was designed to determine the prevalence and risk factors associated with syndromes of sexually transmitted infections in women of reproductive age in the province of Essaouira in Morocco. A questionnaire was distributed to 1100 women using a random sampling technique. Subsequently, a clinical and speculum examination was performed. In this study, 38.6% of the women examined had syndromes of sexually transmitted infections, of which 81.8% had a vaginal discharge. Diagnosed sexually transmitted infection syndromes have been influenced by a woman's level of education, socio-economic status, marital status, obstetric history, and whether the partner is suspected of having other sexual relations. This study revealed a high prevalence of sexually transmitted infection syndromes, and that demands more effort in diagnosis and management should be made.

Text Neck Syndrome: Disentangling a New Epidemic

The aim of this report is to provide a brief review of the predisposing factors for Text Neck Syndrome, along with diagnostic and therapeutic approaches in young and adult populations. Text neck pain is a worldwide public health problem, largely reported nowadays. Currently, data have shown that the erroneous use of personal computers and cell phones might be correlated with the development of various clinical symptoms that are defined as "text neck syndrome". Modified radical changes in everyday life may ameliorate the powerful forces on the cervical spine that can lead to cervical degeneration, along with other developmental, medical, psychological, and social complications that are attributed to text neck syndrome. CONCLUSION: New technologies and the potentially harmful addiction to cell phones and computers while reading or texting are inducing an epidemic of text neck syndrome. By focusing on postural correction, both pain alleviation and a better quality of life can be achieved for the patient. The predisposing factors and therapeutic approaches for this syndrome that affects public health remain to be further elucidated.

Prevalence of metabolic syndrome and related factors in a large sample of antipsychotic naïve patients with first-episode psychosis: Baseline results from the PAFIP cohort

BACKGROUND

Few investigations have been carried out on metabolic syndrome in antipsychotic- naïve patients with schizophrenia.

METHODS

Our primary objective was to compare the prevalence of Metabolic Syndrome (MetS), as defined by the National Cholesterol Education Program, Adult Treatment Panel III in 2001 (NCEP-ATP III), between a Spanish cohort of 303 drug-naïve patients with a first episode of psychosis (FEP) without any previous cardiovascular condition, and 153 healthy individuals.

RESULTS

Participants included 303 patients with FEP (M:F 53:46) and 153 control subjects (M:F 56:43). The mean and standard deviation ages were 31(9.38) and 29 (7.57) years in the study and control groups respectively (F = 4.09; p = 0.93). We found that the prevalence of MetS in drug-naïve patients with FEP (5.6 %) was similar to the prevalence of MetS in age-sex matched controls (5.12 %). However, 60.7 % of patients with FEP met at least one of the five MetS components, while among the control subjects only 36.5 % met at least one component. Additionally, we found that other factors not included among the operational definition of MetS, but still important in cardiovascular risk, were also altered.

CONCLUSION

FEP patients have a greater risk of presenting at least one altered MetS component than healthy controls which could indicate the need of development of screening methods detecting cardiovascular risk. Likewise, gender differences in metabolic components such as waist circumference, which is a predictor of cardiovascular events have been found. Similarly, research should focus on metabolic risk predictors that include not only MetS, but also specific parameters for the early psychosis population.

Signs and syndromes in acute appendicitis: A pathophysiologic approach

Physical examination signs have not been well studied, and their accuracy and reliability in diagnosis remain unknown. The few studies available are limited in that the method of performing the sign was not stated, the technique used was not standardized, and the position of the appendix was not correlated with imaging or surgical findings. Some appendiceal signs were written in a non-English language and may not have been appropriately translated (e.g., Blumberg-Shchetkin and Rovsing). In other cases, the sign described differs from the original report (e.g., Rovsing, Blumberg-Shchetkin, and Cope sign, Murphy syndrome). Because of these studies limitations, gaps remain regarding the signs’ utility in the bedside diagnosis of acute appendicitis. Based on the few studies available with these limitations in mind, the results suggest that a positive test is more likely to be found in acute appendicitis. However, a negative test does not exclude the diagnosis. Hence, these tests increase the likelihood of ruling in acute appendicitis when positive but are less helpful in ruling out disease when negative. Knowledge about the correct method of performing the sign may be a valuable adjunct to the surgeon in further increasing their pretest probability of disease. Furthermore, it may allow surgeons to study these signs further to better understand their role in clinical practice. In the interim, these signs should continue to be used as a tool to supplement the clinical diagnosis.
