A prospective long-term evaluation of the ocular findings of children followed with the diagnosis of multisystem inflammatory syndrome (long-term evaluation of ocular findings following MIS-C)

BACKGROUND/OBJECTIVES

The most frequently reported ocular finding in the acute phase of the multisystem inflammatory syndrome in children (MIS-C), is conjunctivitis. More rarely, punctuate epitheliopathy, anterior uveitis and optic disc oedema can be seen. We aimed to investigate the acute and long-term ocular effects of MIS-C.

SUBJECTS/METHODS

Cases aged 1 month to 18 years who were diagnosed with MIS-C between January 2022 and June 2022 in the Department of Pediatric Infectious Diseases in our hospital were included in the study. Ophthalmological examinations were performed immediately after diagnosis, at one month, three months, and six months.

RESULTS

Males consisted of 64.7% of the 34 cases included in the study and the mean age was 8.68 ± 4.32 years (min-max:2-17). In the first examination, conjunctivitis was observed in 6 (17.6%), punctuate epitheliopathy in 4 (11.7%), and subconjunctival haemorrhage in 3 (8.8%) patients. Two patients (5.8%) had optic disc oedema. No pathological anterior or posterior segment findings were observed in the sixth-month examination. The relationship between subconjunctival haemorrhage and intensive care hospitalisation was statistically significant (p = 0.014). Also, all patients with subconjunctival haemorrhage were clinically classified as severe MIS-C (p = 0.002).

CONCLUSION

Although pathological ocular findings were observed in the acute phase of the disease, all of them were found to be improved at the sixth-month follow-up. The most striking finding of our study is that cases with subconjunctival haemorrhage were clinically more severe, and all patients needed intensive care. This study may be informative in establishing ocular follow-up protocols that are expected to be carried out in the acute period and in the follow-up of these patients.

Diagnostic Accuracy of SARS-CoV-2 Rapid Antigen Testing in a Pediatric Population: Children are Not Little Adults

BACKGROUND

Information on the use of antigen-based SARS-CoV-2 rapid antigen tests (RAT) in children is limited. RATs have been used more frequently, because they are easily applicable, inexpensive, and can be easily performed at home without the need for special equipment. This study was designed to assign the diagnostic test accuracy of the SARS-CoV-2 RAT in daily clinical practice in children.

METHODS

One thousand forty-two pediatric patients (aged 1 month - 18 years) who presented to the pediatric COVID-19 outpatient clinic of our hospital between January 2021 and June 2022 and met the inclusion criteria were included in this study. Nasopharyngeal samples were taken from the patients at the same visit, first for reverse transcription polymerase chain reaction (RT-PCR) and then for RAT.

RESULTS

The data of all patients with RT-PCR positivity (n = 314) and additionally 14 patients with RAT positivity were analyzed in depth. The overall sensitivity and specificity were 62.1% (95% CI: 56.4 - 67.4) and 98% (95% CI: 96.7 - 98.9), respectively. The positive predictive value (PPV) and the negative predictive value (NPV) in this pediatric study were 93.3% and 85.7% (95% CI: 88.7 - 96.1 and 83.1 - 87.9), respectively. Considering the Ct values, which are indirect indicators of viral load, it was observed that the sensitivity of the rapid antigen test increased at low Ct values. The sensitivity increased to 75.1% (95% CI: 67.9 - 81.1) in patients with a Ct value of < 25. The specificity was 92.7% (95% CI: 90.7 - 94.3), PPV was 67.8% (95% CI: 60.7 - 67.8) and the NPV was 94.7% (95% CI: 93.0 - 96.1) in patients with a Ct value < 25. When the patients were evaluated according to their symptomatic/asymptomatic status, the difference between the diagnostic performance of the RAT test was found to be statistically significant (p = 0.006).

CONCLUSIONS

In our study, it was found that the sensitivity of RATs in pediatric patients was lower than in adults. Our results also showed that children are not small adults, and the sensitivity of the test was higher, especially in symptomatic patients and patients with high viral load. To obtain more accurate results, we believe that performing the test in the first 3 days of symptoms will give more accurate results.

Prevalence of rectus diastasis is higher in patients with inguinal hernia

PURPOSE

To determine the prevalence of rectus diastasis (RD) in patients with inguinal hernia.

MATERIAL AND METHODS

Multicenter, cross-sectional study. Patients with inguinal hernia were included in the study group (IH) and those with benign proctologic complaints created the control group (CG). Age, gender, BMI, family history for inguinal hernias, comorbid diseases, alcohol use, smoking, constipation, malignancy, chemotherapy, number of births, multiple pregnancies and prostate hypertrophy history of all patients in both groups were recorded. All patients were evaluated for RD and umbilical hernias by physical examination.

RESULTS

A total of 528 consecutive patients were included in the study (292 IH / 236 CG). Overall prevalence of RD was 35.6% and it was significantly higher in IH than in CG (46.9% vs 21.6%, p < 0.001). Also, umbilical hernia was more frequently detected in the patients with inguinal hernia. Other risk factors for RD were age, BMI, DM, BPH and smoking. The mean inter-rectus distance for 528 patients was 18.1 mm; it was 20.71 ± 10.68 mm in IH and 14.88 ± 8.82 in CG (p < 0.001). It was determined that the increase in age and BMI caused an increase in the inter-rectus distance, and that the presence of DM, inguinal hernia and umbilical hernia increased the inter-rectus distance quantitatively.

CONCLUSIONS

The prevalence of RD seems to be higher in patients with inguinal hernia comparing to that in general population. Increased age, high BMI and DM were found to be independent risk factors for RD development.

Coronavirus Disease 2019-Associated Neurological Manifestations in Children: A Large Single-Center Experience With Rare Cases

BACKGROUND

We aimed to analyze pediatric patients with coronavirus disease 2019 (COVID-19) with a diverse spectrum of neurological manifestations in a single center since neurological involvement in children is still poorly understood.

METHODS

We performed a retrospective study on 912 children aged between zero and 18 years who had a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test result and symptoms of COVID-19 from March 2020 to March 2021 in a single center.

RESULTS

Among 912 patients, 37.5% (n = 342) had neurological symptoms and 62.5% (n = 570) had no neurological symptoms. The mean age of patients with neurological symptoms was significantly higher (14.2 ± 3.7 vs 9.9 ± 5.7; P < 0.001). Three hundred and twenty-two patients had nonspecific symptoms (ageusia, anosmia, parosmia, headache, vertigo, myalgia), whereas 20 patients had specific involvement (seizures/febrile infection-related epilepsy syndrome, cranial nerve palsy, Guillain-Barré syndrome and variants, acute disseminated encephalomyelitis, central nervous system vasculitis). The mean age of the patients with nonspecific neurological symptoms was significantly higher (14.6 ± 3.1 vs 7.7 ± 5.7; P < 0.001).

CONCLUSION

This study presents a large number of patients with a diverse spectrum of neurological manifestations. The rare neurological manifestations reported in our study will contribute to better understanding the neurological involvement of SARS-CoV-2 in children. The study also points out the differences of SARS-CoV-2-related neurological manifestations between patients at different ages. Physicians should be alert about recognizing the early neurological manifestations of the SARS-CoV-2 in children.

Does onlay mesh placement in emergency laparotomy prevent incisional hernia? A prospective randomized double-blind study

PURPOSE

The objective of this study is to assess the effectiveness and safety of onlay mesh closure of emergency midline laparotomy to prevent incisional hernia.

METHODS

This is a prospective randomized double-blind study and was carried out in the General Surgery Clinic, Konya City Hospital, from August 1, 2020 to August, 1, 2021. The study included 108 patients who were randomly grouped in 2 groups: patients with conventional abdominal closure and closure using additional onlay mesh (1:1). The follow-up period was for a year. The primary outcome was the incidence of incisional hernia and secondary outcomes were clinical data like complications, hospital length of stay, re-operations.

RESULTS

It was observed that incisional hernia was present in 14 patients (27.4%) in conventional abdominal closure group and was in 2 patients using mesh (4%), (p = 0.001). Clavien-Dindo 3B complications were in rise in conventional closure group (p = 0.02). Of all complications, burst abdomen was significantly more common in conventional closure group (p = 0.04). The rate of surgically treated complications were higher in conventional closure group (p = 0.02). Clavien-Dindo 3A complications were more common in patients with contaminated wound in mesh group (p = 0.02).

CONCLUSION

The use of mesh while closing the abdomen in emergency midline laparotomy reduces the risk of incisional hernia. Thus, to lower the risks of incisional hernia and its complications, prophylactic mesh can be used in high-risk patients.

Serum Amyloid A Levels and Severity of COVID-19 in Children

OBJECTIVE

The aim of this study was to determine the availability of serum amyloid A (SAA) in the diagnosis of coronavirus disease 2019 (COVID-19), to asses disease severity and to predict hospitalization status.

METHODS

Between March, 2020 and March, 2021, a total of 80 children (40 cases with COVID-19 and 40 cases in healthy group) were included in this study. Patients were divided into two groups (mild and moderate/severe) to evaluate SAA levels in terms of clinical severity and also hospitalization status.

RESULTS

Comparisons between the two groups revealed that median SAA values were significantly higher in children with COVID-19 than in their healthy peers (21.45vs3.05 mg/L, P=0.002). There was no significant difference in the median serum SAA levels between mild and moderate/severe clinical disease (P=0.837). The SAA difference between the two groups with regards to hospitalization was not statistically significant (P=0.098).

CONCLUSIONS

Although SAA level was found to be higher in children with COVID 19 compared to healthy controls, the sensitivity of SAA for the disease was found to be low. In addition, there was no difference between the groups in terms of clinical severity.

Can Serum 25 hydroxy Vitamin D Levels Predict the Severity of Multisystem Inflammatory Syndrome in Children and COVID-19?

OBJECTIVE

To determine the clinical significance of serum 25 hydroxy (OH) vitamin D levels in pediatric patients with multisystem inflammatory syndrome (MIS-C) and compare the vitamin D levels of these patients with those patients with COVID-19 and healthy controls.

METHODS

This study was designed for pediatric patients who were aged 1 month to 18 years between July 14 and December 25, 2021. Fifty-one patients with MIS-C, 57 who were hospitalized with COVID-19, and 60 controls were enrolled in the study. Vitamin D insufficiency was defined as a serum 25 OH vitamin D level of less than 20 ng/mL.

RESULTS

The median serum 25 (OH) vitamin D was 14.6 ng/mL in patients with MIS-C, 16 ng/mL in patients with COVID-19, and 21.1 ng/mL in the control group (p<0.001). Vitamin D insufficiency was present in 74.5% (n=38) of patients with MIS-C, 66.7% (n=38) of patients with COVID-19, and 41.7% (n=25) of the controls (p=0.001). The percentage of four or more affected organ systems was 39.2% in patients with MIS-C. The correlation between the number of affected organ systems and serum 25 (OH) vitamin D levels was evaluated in patients with MIS-C and there was a moderate negative correlation (r= -0.310; p=0.027). A weak negative correlation was found between the severity of COVID-19 and serum 25 (OH) vitamin D (r= -0.320, p=0.015).

CONCLUSION

It was found that vitamin D levels were insufficient in both groups and correlated with the number of affected organ systems of MIS-C and the severity of COVID-19.

P-125 INCIDENCE OF DIASTASIS RECTI ABDOMINIS SEEMS TO BE HIGHER IN PATIENTS WITH INGUINAL HERNIAS

Aim

To find the incidence of Diastasis Recti Abdominis (DRA) in patients with inguinal hernias.

Materials and Methods

Prospective, multicenter, cross-sectional study. Patients with inguinal hernias constitues the study group (IH), and patients with proctological disorders in the control group (PC). Investigated parameters: age, gender, BMI, family history, systemic comorbidities, alcohol consumption, tobacco use, constipation, malignancies, chemotherapy, number of births, multiple pregnancies, prostate hypertrophy. The measurements were done at 3 cm above the umbilicus. Any separation ≥20 mm was accepted as DRA. The existence of paraumbilical hernia (PUH)was also recorded.

Results

36 female and 212 male patients with a mean age of 51.3± 1.4 in IH, whereas 137 women and 305 men with a mean age of 44.5±15.9 in PC. 48.0% of IH and 21.1% of PC were diagnosed with DRA (p=0.001). Incidences of PU were 16.5% and %5.2 respectively (p=0.01). BMI ≥25, chronic pulmonary disease, multiple pregnancies and prostatic enlargement were associated with DRA. Multivariate analysis revealed that inguinal hernia and multiple pregnancies were independent factors for DRA.

Conclusions

Incidences of DRA and PUH seem to be higher in patients with inguinal hernias in comparison with control subjects.

P-019 BIOELECTRIC IMPEDANCE ANALYSIS TO DETERMINE THE RISK FACTORS FOR INGUINAL HERNIA

Aim

To search the risk factors for inguinal hernia development by performing bioelectrical impedance analysis.

Material & Methods

Prospective, multicenter, cross-sectional study. Patients with inguinal hernias constitues the study group (IH), and patients who admitted with other surgical problems in the control group (SC). Age, gender, and BMI of the patients were recorded. Body composition measurements were done by bioelectrical impedance analysis. The relations between the obtained parameters and inguinal hernia were evaluated.

Results

9 female and 125 male patients with a mean age of 53.4± 15.4 in IH, whereas 44 women and 24 men with a mean age of 44.5±15.9 in (SC). There were statistically significant differences between two groups regarding BMI, total body fat, lean abdominal muscle mass, abdominal fat amount, and visceral fat rates. Male gender, low total body fat rate, low total body fat amount, low lean body mass rate, and low visceral fat rate were determined as risk factors for inguinal hernia in univariate analysis. Only low total body fat rate was found to be an independent risk factor.

Conclusions

Low total body fat rate is an independent risk factor for inguinal hernia development.

Influenza is More Severe than Our Newest Enemy (COVID-19) in Hospitalized Children: Experience from a Tertiary Center

Understanding differences in terms of clinical phenotypes and outcomes of coronavirus disease 2019 (COVID‐19) compared with influenza is vital to optimizing the management of patients and planning healthcare. Herein, we aimed to investigate the clinical differences and outcomes in hospitalized patients with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) and influenza. We performed a retrospective study of hospitalized children who were positive for SARS‐CoV‐2 between March 2020 and March 2021 and for influenza between January 2016 and February 2020 in respiratory samples. The primary outcome of this study was pediatric intensive care unit (PICU) admission, and the secondary outcome was the need for respiratory support. A total of 74 patients with influenza and 71 who were positive for SARS‐CoV‐2 were included. The distribution among the sexes was similar, but patients with COVID‐19 were older than patients with influenza (96 vs. 12, p < 0.001). In terms of underlying chronic diseases, the frequency was 26.7% in the COVID‐19 group and 54% in the influenza group (p = 0.001). The comparison of symptoms revealed that fatigue, headache, nausea, vomiting, and abdominal pain occurred more frequently with COVID‐19 (for all p < 0.05) and runny nose with influenza (p = 0.002). The frequency of admission to the PICU was relatively higher (18.9%) in the influenza group than with COVID‐19 (2.8%) with a significant ratio (p = 0.001), secondary bacterial infections were observed more frequently in the influenza group (20.2% vs. 4.2%, p = 0.003). Some 88.7% of patients with COVID‐19 did not need respiratory support, whereas 59.4% of patients with influenza did require respiratory support (p < 0.001). This study noted that influenza caused more frequent admissions to the PICU and a greater need for respiratory support in hospitalized pediatric patients than COVID‐19.

[Role of Hematological Parameters in the Diagnosis of Juvenile Idiopathic Arthritis in Children with Arthritis]

INTRODUCTION

Early diagnosis and treatment of arthritis are essential for the prognosis of the disease. Especially during the active phase of juvenile idiopathic arthritis (JIA), a prompt diagnosis is necessary to ma nage the disease properly. New inflammation markers such as neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), mean platelet volume (MPV), and platelet distribution width (PDW) have been investigated in various inflammatory disorders. This study aimed at the diagnostic value of NLR, MLR, MPV, and PDW in differentiating JIA in children with arthritis.

PATIENTS AND METHOD

Case-control study with 324 children with arthritis (case group) and 324 healthy children (control group). Additionally, children with arthritis were grouped into JIA and non-JIA. Medical records of children aged 0-18 were retrospectively reviewed. Hematological parameters at the time of diagnosis were recorded. NLR, MLR, MPV, and PDW were analyzed in the study groups.

RESULTS

In the case group, 52.8% were boys, and 47.2% were girls; the mean age was 7.7 ± 4.0 years. The NLR in the case group was significantly higher than the control one (p = 0.001). The mean MPV was lower in the case group than the control group (p = 0.001). There were no differences in NLR and MPV between JIA and non-JIA groups (p = 0.062, p = 0.689). The JIA group's mean PDW was lower than the non-JIA group (p = 0.001).

CONCLUSION

The increase in NLR may indicate inflammation but has no superiority in distinguishing JIA from other arthritis causes. Platelet distribution width was lower in JIA patients, but its clinical utility is limited.

Coronavirus disease 2019 in healthy children: What is the effect of household contact?

BACKGROUND

Coronavirus disease 2019 (COVID-19) in children is milder than in adults. Household virus exposure may affect clinical severity. We aimed to determine the household contact history of patients and its influence on the clinical stage.

METHODS

One hundred and seventy-three pediatric patients with COVID-19 as diagnosed with positive real-time polymerase chain reaction for severe acute respiratory syndrome coronavirus-2 aged 1 month to 18 years were included. Demographic data, laboratory and clinical findings, and the history of household contact of the patients were obtained. They were classified according to their clinical stage as mild or moderate-severe.

RESULTS

Sixty patients (34.7%) were asymptomatic, and 113 were symptomatic (65.3%). Of the 173 patients, 138 (79.8%) had at least one family member in the household who was diagnosed as having COVID-19. Hemoglobin, absolute neutrophil count, and absolute neutrophil count /absolute lymphocyte count ratio decreased significantly in patients with household contact. The presence of a household contact did not have a significant effect on the presence of symptoms, clinical course, age, and the sex of the patients. The need for hospitalization was less in the group that had household contact. Being 0-12 months, being female, and being a patient without household contact were independent factors associated with higher hospitalization ratios in logistic regression analysis.

CONCLUSIONS

In this study, we found that household contact history did not significantly affect presenting symptoms and clinical course. We detected the rate of hospitalization to be less in the group with only household contact.

Intestinal microbiota composition of children with infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and multisystem inflammatory syndrome (MIS-C)

Microbiota composition may play a role in the development, prognosis, or post-infection of COVID-19. There are studies evaluating the microbiota composition at the time of diagnosis and during the course of COVID-19, especially in adults, while studies in children are limited and no study available in children with multisystem inflammatory syndrome in children (MIS-C). This study was planned to compare intestinal microbiota composition in children diagnosed with MIS-C and acute COVID-19 infection with healthy children. In this prospective multicenter study, 25 children diagnosed with MIS-C, 20 with COVID-19 infection, and 19 healthy children were included. Intestinal microbiota composition was evaluated by 16 s rRNA gene sequencing. We observed changes of diversity, richness, and composition of intestinal microbiota in MIS-C cases compared to COVID-19 cases and in the healthy controls. The Shannon index was higher in the MIS-C group than the healthy controls (p < 0.01). At phylum level, in the MIS-C group, a significantly higher relative abundance of Bacteroidetes and lower abundance of Firmicutes was found compared to the control group. Intestinal microbiota composition changed in MIS-C cases compared to COVID-19 and healthy controls, and Faecalibacterium prausnitzii decreased; Bacteroides uniformis, Bacteroides plebeius, Clostridium ramosum, Eubacterium dolichum, Eggerthella lenta, Bacillus thermoamylovorans, Prevotella tannerae, and Bacteroides coprophilus were dominant in children with MIS-C. At species level, we observed decreased Faecalibacterium prausnitzii, and increased Eubacterium dolichum, Eggerthella lenta, and Bacillus thermoamylovorans in children with MIS-C and increased Bifidobacterium adolescentis and Dorea formicigenerasus in the COVID-19 group. Our study is the first to evaluate the microbiota composition in MIS-C cases. There is a substantial change in the composition of the gut microbiota: (1) reduction of F. prausnitzii in children with MIS-C and COVID-19; (2) an increase of Eggerthella lenta which is related with autoimmunity; and (3) the predominance of E. dolichum is associated with metabolic dysfunctions and obesity in children with MIS-C.

CONCLUSIONS

 Alterations of the intestinal microbiota might be part of pathogenesis of predisposing factor for MIS-C. It would be beneficial to conduct more extensive studies on the cause-effect relationship of these changes in microbiota composition and their effects on long-term prognosis.

WHAT IS KNOWN

• Microbiota composition may play a role in the development, prognosis, or post-infection of COVID-19.  • However, the number of studies on children is limited, and no study on multisystem inflammatory syndrome in children is currently available (MIS-C).

WHAT IS NEW

• In individuals with MIS-C, the composition of the gut microbiota changed dramatically. • Decreased Faecalibacterium prausnitzii have been observed, increased Eggerthella lenta, which was previously linked to autoimmunity, and predominance of Eubacterium dolichum which was linked to metabolic dysfunction and obesity.

Study of Aqueous Ecballium Elaterium as Fibrinolytic in The Rabbit Model of Intrapleural Empyema

Aims

We aimed to investigate of intrapleural use of ecballium elaterium (EE) in a rabbit model empyema.

Methods

An empyema was induced in 21 rabbits after inoculation of Staphylococcus aureus. Glucose levels, pH, lactate dehydrogenase levels, and amounts of pleural drainage were evaluated in addition to pleural and empyema scores. The rabbits were divided into three groups, each 7, the isotonic solution, the streptokinase, and the ecballium group.

Results

At autopsy, there was no difference in pH, glucose, and LDH levels in three groups. The mean pleural drainage was greater in the ecballium group. A significant difference was detected between groups in terms of drainage amounts and pleural and empyema scores (P < 0.05). A significant difference in pleural and empyema scores was detected in the ecballium and streptokinase groups (P < 0.05). EE group had significant differences in drainage amounts and plural and empyema scores regard to the control group (P < 0.05). No significance was found between streptokinase and EE groups.

Conclusion

We conclude that intrapleural use of EE is at least as effective as streptokinase for the treatment of empyema.

The opioid peptide biphalin modulates human corneal epithelial wound healing in vitro

PURPOSE

Analgesic drugs, including nonselective opioids and non-steroidal anti-inflammatory drugs, should be used with great precautions to relieve pain after trauma to the corneal epithelium because of their unfavorable effects on wound healing. Biphalin is a synthetic opioid peptide that has been demonstrated to possess a strong analgesic effect on rodents. The purpose of this study is to investigate the effects of biphalin on human corneal epithelial wound healing.

METHODS

An immortalized human corneal epithelial cell (HCEC) culture was used to analyze the effects of biphalin on wound healing. The toxicity of biphalin at various concentrations was measured by the MTT assay. The effects of 1μM and 10μM biphalin on wound closure, cell migration and proliferation were tested in an in vitro scratch assay of HCECs. Naloxone, a non-selective competitive opioid receptor antagonist, was also used to inhibit the effects of biphalin in all experiments.

RESULTS

Biphalin did not cause any toxic effect on HCECs at concentrations lower than 100μM at various incubation time points. Biphalin significantly increased wound healing at 1μM concentration in an in vitro scratch assay of HCECs (P<0.05). It also significantly increased migration of HCECs (P<0.01). There was no significant difference between the biphalin and control groups of HCECs in the Ki67 proliferation assay.

CONCLUSION

Biphalin, which is a synthetic opioid peptide, promotes corneal epithelial wound healing by increasing cell migration. This role should be evaluated in further in vivo and clinical studies.

AB0893-HPR TREATMENT SATISFACTION, EXPECTATIONS, PATIENT PREFERENCES, AND CHARACTERISTICS IN PATIENTS WITH RHEUMATOID ARTHRITIS (RA): TURKISH COHORT RESULTS OF THE SENSE STUDY

Background:

Suboptimal control of RA may lead to severe and progressive articular damage, loss of function, and deterioration of the quality of life (QoL).

Objectives:

To assess treatment satisfaction, sociodemographic, clinical, health care resource utilization, and QoL characteristics of patients with sub-optimally controlled RA and treated with conventional synthetic and/or biologic DMARDs.

Methods:

This study was an international, multicenter, cross-sectional, non-interventional study. Adult RA patients with moderate to severe disease activity (DAS28>3.2) were enrolled. Patient satisfaction was evaluated with Treatment Satisfaction Questionnaire for Medication (TSQM, version 1.4) with a scale ranging from 0 (indicating poor satisfaction) to 100 (indicating perfect satisfaction). Patients were questioned regarding treatment adherence, patient preferences, and expectations. Workability was evaluated using Work Productivity and Activity Impairment Questionnaire-Rheumatoid Arthritis (WPAI-RA, version 2.0). Short Form 36 (V2) survey were performed to all patients.

Results:

One hundred sixty-four patients were included in the study and most (78.0%) were female. The median age was 57.0 years, ranging between 22.0 and 84.0 years. Half of the patients (50.6%) were primary school graduates and 6.1% were unemployed due to RA and seeking work. Median time since RA diagnosis was 8.0 years and mean (±SD) DAS28-CRP score was 4.8 (±1.0). Mean total activity impairment was 54.9% (±27.4). In the past 3 months from enrollment, the mean number of healthcare professional and emergency room visits were 1.8 (±1.1) and 1.8 (±1.3), respectively. Mean number and length of hospitalizations in the previous 3 months were 1.1 (±0.3) times and 8.3 (±7.2) days, respectively. Mean TSQM scores were 53.5 (±21.4) for effectiveness, 86.0 (±26.7) for side effects, 67.8 (±16.5) for convenience, and 57.7 (±22.0) for global satisfaction. The leading expectation was ‘lasting relief of RA symptoms’ (mean score: 5.8). Preferred time until the effect of onset was ‘up to 1 week’ for 76.2% of the patients. Most of the patients (57.9%) preferred oral administrations and the most preferred frequency of administration was ‘once per day’ (46.3%). Mean physical and mental component summary scores for Short Form 36 (V2) survey were 37.9 (±8.3) and 40.1 (±10.7).

Conclusion:

Two-thirds of the patients with RA who have suboptimal responses are not satisfied with their treatments. Moreover, oral and once-daily treatment approaches stand out in patient preferences. Finally, suboptimal control leads to deterioration in clinical characteristics, workability, and QoL of patients with RA.

Crossing mesh tails in the Lichtenstein repair method for medial (direct) inguinal hernia: recurrence and chronic pain rates after five years

PURPOSE

This study aimed to determine whether crossing of the mesh's lateral tails is beneficial in Lichtenstein repairs for medial (direct) inguinal hernias.

METHODS

We allocated 116 patients with unilateral medial (direct) inguinal hernias into two groups: mesh tail crossing (group C) or no mesh tail crossing (group N). In group C, the lateral tails were sutured together at the inguinal ligament, whereas the lateral tails were sutured in a parallel position in group N. Visual analog scale (VAS) scores were postoperatively recorded in person at the 1st, 7th, 30th, and 90th days and at the 1st year. The Short-Form Health Survey (SF-36) scores were calculated postoperatively at one month and one year. Examinations to detect hernia recurrence were performed at the end of the 1st year. Follow-ups at the 5th year were performed via phone calls to obtain the Sheffield pain scale and VAS values and to determine the possibility of hernia recurrence.

RESULTS

VAS and SF-36 scores at the 1st, 7th, 30th, and 90th days and 1st year were all higher in group C than in group N. In group C, one patient experienced moderate pain, and one experienced severe pain. In the 5th year, VAS and Sheffield pain scores were significantly higher in group C than in group N.

CONCLUSIONS

During Lichtenstein repair for medial (direct) inguinal hernias, crossing of the mesh tails may increase the frequency of postoperative chronic inguinal pain.

Epidemiological, Clinical, and Laboratory Features of Children With COVID-19 in Turkey

Objectives: The aim of this study is to identify the epidemiological, clinical, and laboratory features of coronavirus disease 2019 (COVID-19) in children. Methods: A retrospective study was conducted by pediatric infectious disease specialists from 32 different hospitals from all over Turkey by case record forms. Pediatric cases who were diagnosed as COVID-19 between March 16, 2020, and June 15, 2020 were included. Case characteristics including age, sex, dates of disease onset and diagnosis, family, and contact information were recorded. Clinical data, including the duration and severity of symptoms, were also collected. Laboratory parameters like biochemical tests and complete blood count, chest X-ray, and chest computed tomography (CT) were determined. Results: There were 1,156 confirmed pediatric COVID-19 cases. In total, male cases constituted 50.3% (n = 582) and females constituted 49.7% (n = 574). The median age of the confirmed cases was 10.75 years (4.5-14.6). Of the total cases, 90 were younger than 1 year of age (7.8%), 108 were 1-3 years of age (9.3%), 148 were 3-6 years of age (12.8%), 298 were 6-12 years of age (25.8%), 233 were 12-15 years of age (20.2%), and 268 cases were older than 15 years of age (23.2%). The most common symptom of the patients at the first visit was fever (50.4%) (n = 583) for a median of 2 days (IQR: 1-3 days). Fever was median at 38.4°C (38.0-38.7°C). The second most common symptom was cough (n = 543, 46.9%). The other common symptoms were sore throat (n = 143, 12.4%), myalgia (n = 141, 12.2%), dyspnea (n = 118, 10.2%), diarrhea (n = 112, 9.7%), stomachache (n = 71, 6.1%), and nasal discharge (n = 63, 5.4%). When patients were classified according to disease severity, 263 (22.7%) patients were asymptomatic, 668 (57.7%) patients had mild disease, 209 (18.1%) had moderate disease, and 16 (1.5%) cases had severe disease. One hundred and forty-nine (12.9%) cases had underlying diseases among the total cases; 56% of the patients who had severe disease had an underlying condition (p < 0.01). The need for hospitalization did not differ between patients who had an underlying condition and those who do not have (p = 0.38), but the need for intensive care was higher in patients who had an underlying condition (p < 0.01). Forty-seven (31.5%) of the cases having underlying conditions had asthma or lung disease (38 of them had asthma). Conclusions: To the best of our knowledge, this is one of the largest pediatric data about confirmed COVID-19 cases. Children from all ages appear to be susceptible to COVID-19, and there is a significant difference in symptomatology and laboratory findings by means of age distribution.

Effects of resveratrol on alpha-amanitin-induced nephrotoxicity in BALB/c mice

Alpha-amanitin (α-AMA), the primary toxin of Amanita phalloides, is known to cause nephrotoxicity and hepatotoxicity. Resveratrol is an antioxidant that has shown efficacy in many nephrotoxicity models. The aim of this study was to investigate the effects of resveratrol against the early and late stages of α-AMA-induced nephrotoxicity, compared to those of silibinin, a well-known antidote for poisoning by α-AMA-containing mushrooms. Mice kidney tissues were obtained from five groups: (1) α-AMA + NS (simultaneous administration of α-AMA and normal saline), (2) α-AMA + SR (simultaneous administration of α-AMA and resveratrol), (3) α-AMA + 12R (resveratrol administration 12 h after α-AMA administration), (4) α-AMA + 24R (resveratrol administration 24 h after α-AMA administration), and (5) α-AMA + Sil (simultaneous administration of α-AMA and silibinin). Histomorphological and biochemical analyses were performed to evaluate kidney damage and oxidant-antioxidant status in the kidney. Scores of renal histomorphological damage decreased significantly in the early resveratrol treatment groups (α-AMA + SR and α-AMA + 12R), compared to those in the α-AMA + NS group (p < 0.05). Catalase levels increased significantly in the α-AMA + SR group, compared to those in the α-AMA + NS group (p < 0.001). Early resveratrol administration within 12 h after α-AMA ingestion may reverse the effects of α-AMA-induced nephrotoxicity, partly through its antioxidant action, thereby suggesting its potential as a treatment for poisoning by α-AMA-containing mushrooms.

Characterization of bevacizumab by dynamic light scattering while maintaining its native structure

Bevacizumab, is a humanized monoclonal antibody and patents on Avastin® (Bevacizumab, Roche) will expire in the US in 2019 and in Europe in 2022. Therefore, bevacizumab is a popular target for biosimilar developers. One of the most common problems in the formulation of antibody drugs is protein aggregation. Dynamic light scattering (DLS) is a well-established method for the determination of hydrodynamic dimensions, aggregates, and aggregation points of proteins. In contradistinction to other techniques that require diluted samples or specific conditions, proteins and aggregates can maintain their native structure during DLS measurements. In recent studies, bevacizumab was characterized by DLS using diluted samples. In this study, we aimed at investigating the hydrodynamic dimensions, aggregates, and aggregation onset of bevacizumab (Altuzan®, Turkey, Roche) by DLS, while maintaining its native structure. The intensity, volume, and number-based particle size distribution profiles of the test samples were evaluated and the aggregation onset of the formulation was successfully determined against increasing temperature. It is shown that the preservation of the native structure of commercial formulations in DLS measurements provides an opportunity to the characterization of commercial products and development of biosimilars.

The diagnostic value of the serum irisin level in patients with acute pericarditis and acute myopericarditis

OBJECTIVE

This preliminary study aims to examine a change in the blood levels of irisin in patients with acute pericarditis (AP) and acute myopericarditis (AMP) and examine the diagnostic value of the serum irisin level in AP and AMP.

METHODS

10 patients, who applied to the emergency service and cardiology clinic with chest pain and who were diagnosed with AP and 5 patients, who were diagnosed with AMP as a result of routine examinations, were included in the study. The basal laboratory parameters, echocardiography findings and serum irisin levels of the patients and during check one month later were examined.

RESULTS

While the basal irisin levels were found to be significantly low in the AMP group and high during the check (6.6 ± 1.58, 8.19 ± 1.43, respectively), no statistically significant difference was determined (p = 0.23). It was observed that the basal and control irisin levels did not vary significantly in the AP group (8.03 ± 1.6, 8.19 ± 1.43, respectively) (p = 0.84).

CONCLUSION

In this preliminary study, the basal irisin levels were found to be significantly low in the AMP group, while there was no statistically significant difference between the basal irisin levels and control irisin levels in the AP and AMP groups (Tab. 5, Ref. 17).

Using PVA and TPGS as combined emulsifier in nanoprecipitation method improves characteristics and anticancer activity of ibuprofen loaded PLGA nanoparticles

In the preparation of nanoparticles (NPs) by the nanoprecipitation method, emulsifiers play a key role for NPs' characteristics. The present study aimed to investigate the combined emulsifier effect on ibuprofen loaded poly(lactic-co-glycolic acid) (PLGA) NPs' characteristics and anticancer activity. Ibuprofen loaded PLGA NPs were prepared by nanoprecipitation using different concentrations of PVA (poly(vinyl alcohol)) or PVA-TPGS (d-α-tocopherol polyethylene glycol 1000 succinate) combination as emulsifier. It was found that encapsulation efficiencies of NPs varied between 17.9 and 41.9 % and the highest encapsulation efficiency was obtained with 0.5% PVA + 0.1% TPGS (coded as PLGA PVA/TPGS NPs). PLGA PVA/TPGS NPs were characterized and compared with PLGA PVA NPs, which was obtained by 0.5% PVA alone. Polydispersity index of PLGA PVA/TPGS and PLGA PVA NPs were found to be 0.08 and 0.15, respectively. Incorporation of TPGS with PVA slightly decreased the initial ibuprofen release. Transmission electron microscopy analyses demonstrated a nearly uniform particle size distribution and spherical particle shape of the PLGA PVA/TPGS NPs. Additionally, PLGA PVA/TPGS NPs were significantly more cytotoxic than PLGA PVA NPs on the MCF-7 (human breast adenocarcinoma cells) and Caco-2 (human epithelial colorectal adenocarcinoma) cells (p<0.05). Also PLGA PVA/TPGS NPs were not cytotoxic on normal cells (L929, mouse healthy fibroblast cells) (p>0.05). In conclusion, these results indicated that using a combination of TPGS and PVA as an emulsifier in nanoprecipitation could be a promising approach for preparing ibuprofen loaded PLGA NPs because of their improved characteristics and anticancer activity.

Development and validation of a LC-FL method for the simultaneous determination of doxorubicin and celecoxib in nanoparticulate fixed dose combination (NanoFDC)

An isocratic reversed phase HPLC method for the simultaneous determination of doxorubicine (DOX) and celecoxib (CXB) out of a nanoparticulate fixed dose combination (NanoFDC) was developed and validated. Linearity of the results was demonstrated from 1-11 μg/mL for both components. Lower limits of detection were determined as 7 ng/mL for DOX and 13 ng/mL for CXB. Total run time was approximately 15 min.

The effect of mad honey on testosterone levels of male rats

OBJECTIVE

We aimed to investigate the effect of mad honey on sexual performance.

BACKGROUND

In traditional medicine in Turkey, mad honey is used to improve appetite, to heighten mental alertness, to reduce joint pain, to eliminate gastrointestinal system pains and to increase sexual performance.

METHODS

In this experimental animal study eighteen Sprague Dawley male rats were randomized into three groups, a control group, a normal honey group and a mad honey group. Rats in the treatment groups were given a daily dose of 80 mg/kg normal honey or mad honey throughout the 30-day study period. Total testosterone, free testosterone, FSH, LH, estradiol, and progesterone levels were subsequently investigated from blood sera on day 30.

RESULTS

Comparison of blood total testosterone levels among the groups revealed significantly higher levels in the mad honey group compared to the normal honey and control groups (p = 0.006, p = 0.00). Free testosterone levels were also significantly higher in the mad honey group than in the normal honey and control groups (p = 0.023, p = 0.01). No statistically significant differences were determined for other hormonal measurements.

CONCLUSIONS

This study revealed a significant increase in both total and free testosterone levels in mad-honey group (Tab. 1, Fig. 2, Ref. 16).

Dissection of Signaling Pathways in Fourteen Breast Cancer Cell Lines Using Reverse-Phase Protein Lysate Microarray

Signal transduction pathways play a crucial role in breast cancer development, progression, and response to different therapies. A major problem in breast cancer therapy is the heterogeneity among different tumor types and cell lines commonly used in preclinical studies. To characterize the signaling pathways of some of the commonly used breast cancer cell lines and dissect the relationship among a number of pathways and some key genetic and molecular events in breast cancer development, such as p53 mutation, ErbB2 expression, and estrogen receptor (ER)/progesterone receptor (PR) status, we performed pathway profiling of 14 breast cancer cell lines by measuring the expression and phosphorylation status of 40 different cell signaling proteins with 53 specific antibodies using a protein lysate array. Cluster analysis of the expression data showed that there was close clustering of phosphatidylinositol 3-kinase, Akt, mammalian target of rapamycin (mTOR), Src, and platelet-derived growth factor receptor β (PDGFRβ) in all of the cell lines. The most differentially expressed proteins between ER- and PR-positive and ER- and PR-negative breast cells were mTOR, Akt (pThr308), PDGFRβ, PDGFRβ (pTyr751), panSrc, Akt (pSer473), insulin-like growth factor-binding protein 5 (IGFBP5), Src (pTyr418), mTOR (pSer2448), and IGFBP2. Many apoptotic proteins, such as apoptosis-inducing factor, IGFBP3, bad, bax, and cleaved caspase 9, were overexpressed in mutant p53-carrying breast cancer cells. Hexokinase isoenzyme 1, ND2, and c-kit were the most differentially expressed proteins in high and low ErbB2-expressing breast cancer cells. This study demonstrated that ER/PR status, ErbB2 expression, and p53 status are major molecules that impact downstream signaling pathways.

Neutrophil-to-lymphocyte ratio is involved in the severity of ankylosing spondylitis

OBJECTIVE

Ankylosing spondylitis (AS) is a progressive chronic inflammatory disease mainly characterized by axial skeleton and sacroiliac joint involvement. We aimed to investigate the relation between neutrophil-to-lymphocyte ratio (NLR) and disease severity of AS and to explore its availability in clinical practice.

METHODS

A total of 102 AS patients and 60 individuals who were age- and gender-compatible with the control group were included into the study. Patients were divided into 2 groups according to Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores. Patients with BASDAI scores < 4 were considered to be having mild disease activity, whereas those with scores ≥ 4 were considered to be displaying severe disease activity. Hemogram test during the diagnosis, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) and other laboratory values of the control group were recorded.

RESULTS

NLR was observed to be higher in AS patients compared to the controls (2.47 ± 1.33 and 1.72 ± 0.47; respectively; p<0.0001). NLR was observed to be significantly higher in severe AS disease activity compared to the mild AS disease activity (2.72 ± 1.41, 2.20 ± 1.19; respectively; p = 0.001). NLR had statistical significant differences between mild disease activity compared to the controls (2.20 ± 1.19 and 1.72 ± 0.47, respectively; p = 0.263). There was a positive correlation between NLR and BASDAI (r = 0.193, p = 0.041). The performance of NLR evaluating the disease severity by Roc analysis had sensitivity of 69%, specificity of 54% (cut-off value 1.91), and AUC of 0.652 (95% Cl, 0.549-0.755) (p = 0.006).

CONCLUSIONS

NLR may be a simple and inexpensive marker to indicate disease activity in patients with AS in daily clinical practice (Tab. 3, Fig. 3, Ref. 25).

Evaluation of human chaperonin 10 and high-sensitivity C-reactive protein levels of infertile women who underwent ovulation induction and intra-uterine insemination

INTRODUCTION

The implantation of embryo is one of the crucial steps of a successful pregnancy. The foetus should be protected from maternal immune system, for the appropriate implantation and modification in maternal immunity is crucial. We investigated high-sensitivity C-reactive protein (hs CRP), which is an indicator of low-grade inflammation and Cp10 that has immunosuppressant and growth-promoting capabilities at embryo levels in ovulation induction and intra-uterine insemination (IUI)applied in infertile women. The ovulation induction was maintained by clomiphene citrate or gonadotropins for 42 infertile patients. After successful ovulation induction, IUI was carried out. The blood samples were taken 2 and 8 days after IUI to evaluate Cp10 and hs CRP levels. The pregnant and non-pregnant groups' results were analyzed. The Cp10 levels 8 days after IUI were higher in pregnant group, whereas there was no difference for the 2 days after levels between pregnant and non-pregnant group. The hs CRP levels were similar for both 2nd and 8th days when we compared pregnant and non-pregnant groups. The Cp10 levels increased from day 2 to day 8 in pregnant group. In contrast, the Cp10 levels decreased in non-pregnant group. The change in hs CRP levels from day 2 to day 8 was not significant in pregnant and non-pregnant groups. The Cp10 levels were higher in early phases of fertilisation and elevated through the preceding days of conception in pregnant patients, while it decreased in non-pregnant patients with failed cycles.

Surgical outcome of bronchiectasis in children: long term results of 60 cases

BACKGROUND

Bronchiectasis is described as destruction and the irreversible dilatation of bronchial structure. We wanted to demonstrate our surgical practice and outcome of surgical treatment in bronchiectasis.

METHODS

We studied records of 60 pediatric patients who underwent surgical resection in our clinic between January 2000 and January 2013. The results were analyzed regarding factors influencing the outcome.

RESULTS

There were 32 boys and 28 girls with a mean age of 9.45 years (range 2-15). The most common cause was childhood infection in 25 (41.66%). The mean duration of the symptoms was 42.93 months. Patients underwent 64 operations including 2 staged thoracotomies and 2 re-thoracotomies. Atelectasis was the most frequent complication. Longer duration of symptoms related to postoperative complication. The morbidity and mortality rates were 20% and 3.33%, respectively. The outcome was optimal in 92%. Forced expiratory volume in 1 s less than 60% of the predicted value, hemoptysis and duration of symptoms were found prognostic variables for postoperative morbidity with high ratios of odds coefficients by using Binary Logistic Regression Method.

CONCLUSIONS

Complete and early resection of bronchiectasis provides a successful outcome. Duration of symptoms and timely intervention have a major impact on the management and prognosis.

Open-label randomized clinical trial of standard neoadjuvant chemotherapy with paclitaxel followed by FEC versus the combination of paclitaxel and everolimus followed by FEC in women with triple receptor-negative breast cancer†

BACKGROUND

Everolimus synergistically enhances taxane-induced cytotoxicity in breast cancer cells in vitro and in vivo in addition to demonstrating a direct antiproliferative activity. We aim to determine pharmacodynamics changes and response of adding everolimus to standard neoadjuvant chemotherapy in triple-negative breast cancer (TNBC).

PATIENTS AND METHODS

Phase II study in patients with primary TNBC randomized to T-FEC (paclitaxel 80 mg/m(2) i.v. weekly for 12 weeks, followed by 5-fluorouracil 500 mg/m(2), epirubicin 100 mg/m(2), and cyclophosphamide 500 mg/m(2) every 3 weeks for four cycles) versus TR-FEC (paclitaxel 80 mg/m(2) i.v. and everolimus 30 mg PO weekly for 12 weeks, followed by FEC). Tumor samples were collected to assess molecular changes in the PI3K/AKT/mTOR pathway, at baseline, 48 h, 12 weeks, and at surgery by reverse phase protein arrays (RPPA). Clinical end points included 12-week clinical response rate (12-week RR), pathological complete response (pCR), and toxicity.

RESULTS

Sixty-two patients were registered, and 50 were randomized, 27 received T-FEC, and 23 received TR-FEC. Median age was 48 (range 31-75). There was downregulation of the mTOR pathway at 48 h in the TR-FEC arm. Twelve-week RR by ultrasound were 29.6% versus 47.8%, (P = 0.075), and pCR were 25.9% versus 30.4% (P = 0.76) for T-FEC and TR-FEC, respectively. mTOR downregulation at 48 h did not correlate with 12-week RR in the TR-FEC group (P = 0.58). Main NCI grade 3/4 toxicities included anemia, neutropenia, rash/desquamation, and vomiting in both arms. There was one case of grade 3 pneumonitis in the TR-FEC arm. No grade 3/4 stomatitis occurred.

CONCLUSION

The addition of everolimus to paclitaxel was well tolerated. Everolimus downregulated mTOR signaling but downregulation of mTOR at 48 h did not correlate with 12-week RR in the TR-FEC group.

Prevalence of sleep disturbance in chronic pain

OBJECTIVE

Sleep is a vital function for human beings, which can be affected by several factors. Chronic pain is one of these factors where it is the most frequent cause for seeking medical care in combination with insomnia. The aim of this study is to examine the prevalence and relationship between sleep disturbance and chronic pain.

PATIENTS AND METHODS

After approval, a total of 85 Family Medicine Units from over 170 in Tokat were randomly selected using a 50% sampling. A sample of 2635 subjects, over the age of 19 years, who were registered with the selected Family Medicine Units, were assessed due to gender, age group, and the urban/rural population size of Tokat using the stratified sampling method. The sample size distribution was calculated as 1515 urban subjects, 1120 rural subjects; 1345 female subjects, 1290 male subjects; 1123 subjects between 20-39 years of age, 1103 subjects between the ages of 40-64, and 409 subjects over 64 years of age. After sampling, subjects were invited to participate in the study via an invitation letter, and agreeing individuals were taken to the Family Medicine Unit for face-to-face meetings. Written, informed consent was obtained, along with demographic data. The presence of chronic pain was recorded. According to the presence of chronic pain, all subjects were separated into two groups as Group Chronic Pain and Group Non-Chronic Pain. The visual analog scale for pain intensity, and Pittsburgh Sleep Quality Index for sleep quality, were performed with all subjects. A multiple linear regression model was used to assess the predictors of sleep quality. Analyses were conducted using the Statistical Package for Social Sciences program (SPSS Inc., Chicago, IL, USA), version 20.0. The statistical significance for all analyses was set at p < 0.05.

RESULTS

The mean global Pittsburgh Sleep Quality Index score of Group Chronic Pain (5.30 ± 4.29) was significantly higher than in Group Non-Chronic Pain (3.22 ± 3.30; p < 0.01). The mean Pittsburgh Sleep Quality Index scores of females (5.69 ± 4.40) were significantly higher than males (4.54 ± 3.96) in Group Chronic Pain (p = 0.000045). A total of 40.7% of patients in Group Chronic Pain, and 21.9% in Group Non-Chronic Pain demonstrated poorer sleep quality according to the Pittsburgh Sleep Quality Index scores, with a cut-off level > 5. A moderate positive correlation was found between the global Pittsburgh Sleep Quality Index and Visual Analog Scale scores (r = 0.310, p < 0.01). A multiple linear regression analysis showed that age, gender, income, Visual Analog Scale, and presence of depression were the significant predictors for Pittsburgh Sleep Quality Index score.

CONCLUSIONS

The current study revealed that chronic pain and pain intensity are important predictors of sleep quality.

Malaria epidemiology in mersin province, Turkey from 2002 to 2011

BACKGROUND

Malaria is an infectious disease caused by Plasmodium spp. with high morbidity and mortality in human in tropical and subtropical regions. In recent years, number of malaria cases has been significantly reduced because of fight with the disease in Turkey. This study intended to investigate the malaria epidemiology in Mersin Province from 2002 to 2011 using data from the provincial Public Health Directorate.

METHODS
