Impact of Otitis Media With Effusion in Early Age on Auditory Processing Abilities in Children: A Systematic Review and Meta-Analysis

Objective: Early-onset otitis media with effusion (OME) can affect the development of the auditory nervous system and thus lead to auditory processing abnormalities. This study aims to review the effect of childhood OME on auditory processing abilities in children. Methods: A systematic review of the literature, restricted to the English language from 1990 to 2022 was conducted using search engines like PubMed, Embase, and Google Scholar. After selecting the articles following predefined inclusion and exclusion criteria, the data were extracted and meta-analysis was performed. Results: A total of 10 articles met the inclusion criteria. Children with a history of OME had poorer performance in most behavioral and electrophysiological tests. Pooled analysis of various tests such as the gap in noise test, frequency pattern test (verbal and nonverbal), and latencies of auditory brainstem response-I, V, I to III, and I to V showed a difference between the 2 groups. Conclusion: Childhood OME can significantly affect auditory processing abilities in children.

Amoxicillin-induced bullous erythema multiforme: a case report

Introduction

Bullous erythema multiforme (BEM), an immune-mediated, acute condition, frequently includes erosion affecting the oral, genital, and/or ocular mucosa in addition to discrete target-like lesions on the skin. BEM has been linked to various factors, including infections, medications, malignancy, autoimmune disease, immunization, and radiation.

Case presentation

Here, we report a case of a 38-year-old married woman who presented with symptoms of reddish-raised, fluid-filled and painful, nonpruritic lesions along with the swelling of bilateral hand and feet. This patient had a history of taking some unrecorded ayurvedic medication for bloating and abdominal pain in a background of antibiotic use before exhibiting the dermatological symptoms of BEM 2 days later. She was successfully managed with ampicillin and cloxacillin, acyclovir and prednisolone.

Clinical discussion

A few incidence of BEM after the administration of amoxicillin has been reported, which precipitated only after consuming ayurvedic medication. BEM has a clinical diagnosis with biopsy rarely required. Here, the hypersensitivity reaction induced by the antibiotic itself or by altering the immune response to the concomitant consumed herbal medicine could explain the BEM.

Conclusion

Physicians should note that amoxicillin can trigger BEM, regardless of its use with ayurvedic drugs. Antibiotics should be used with caution, especially in patients with a history of BEM.

Utilization rates of intravenous thrombolysis for acute ischemic stroke in Asian countries:: A systematic review and meta-analysis

BACKGROUND

Despite intravenous thrombolysis (IVT) being used for the treatment of acute ischemic stroke (AIS) for over two decades, its accessibility remains limited in various regions of the world. The Asian region, which experiences the highest age-standardized incidence of AIS, currently lacks comprehensive data on the utilization of IVT.

AIMS

This study aimed to provide precise estimates of IVT usage for AIS in Asian countries.

METHODS

A literature search was conducted on PubMed and Google using appropriate search terms. English language, peer reviewed articles published after 2010 were included in the analysis. The pooled proportion was calculated utilizing the DerSimonian and Laird random-effects model. Additionally, a subgroup analysis was conducted, taking into account factors such as the study's country, the economic status of the country, specific Asian regions, publication year (before 2015 and from 2015 onwards), study location, study setting, hospital stroke protocol, and national stroke guidelines.

RESULTS

67 observational studies with 778,046 patients with AIS were included in the meta-analysis. The overall utilization rate of IVT was found to be 9.1%. High-income countries had a higher rate (11.3%) compared to lower-middle-income (8.1%) and upper-middle-income countries (9%). Central and North Asia had the highest rate (17.5%) and Southeast Asia had the lowest rate (6.8%). Studies conducted after 2015 had a higher thrombolysis rate (11.3%) compared to those before 2015 (1.5%). Presence of hospital stroke protocols (10.7%) and national stroke guidelines (10.1%) were associated with higher thrombolysis rates.

CONCLUSION

The overall utilization rate of IVT for AIS in Asia stood at 9.1%, showcasing noteworthy disparities across countries, regions, and income brackets. To improve thrombolysis rates in the region, addressing prehospital delays, increasing public awareness, and implementing stroke protocols and national guidelines are key strategies.

High-Altitude Exposure and Cerebral Venous Thrombosis: An Updated Systematic Review

Kharel, Sanjeev, Suraj Shrestha, Samriddha Raj Pant, Suman Acharya, Amit Sharma, Santosh Baniya, and Sanjeeb S. Bhandari. High-altitude exposure and cerebral venous thrombosis: an updated systematic review. High Alt Med Biol. 24:167-174, 2023. Background: High altitude (HA) may increase the risk of cerebral venous thrombosis (CVT). Differentiating it from other HA illnesses is crucial for prompt treatment and better outcomes. We aimed to summarize the clinical data, etiology, and risk factors of this poorly understood entity at an HA. Materials and Methods: A systematic literature search of various databases, including PubMed, Embase, and Google Scholar, was done using relevant keywords; cerebral venous thrombosis; HA, up to May 1, 2022. Results: A total of nine studies, including 75 cases of CVT at HA (3,000-8,848 m), with 66 males and 9 females, were included in this review. Headache and seizure were the most common clinical presentations. Smoking, drinking habits, and the use of oral contraceptive pills (OCP) were the most common risk factors for the development of CVT. Similarly, various underlying hypercoagulable states were also present among cases of CVT associated with HA exposure. Conclusion: Our review concludes that HA exposure can predispose individuals with risk factors such as preexisting hypercoagulable states, smoking, drinking habits, and use of OCP to an increased risk of CVT.

Breakage of an orogastric tube in a critically Ill patient: a case report

Orogastric and nasogastric tubes are common methods of enteral feeding. Although the methods of tube feeding are simple, these methods are not free of complications.

Case presentation

This case report describes a 58-year-old patient with the diagnosis of stroke, in whom there was breakage of an orogastric tube during a prolonged ICU stay.

Clinical discussion

Early enteral feeding in patients without any contraindications is associated with improved organ survival and recovery, and decreased incidence of infections, which decreases the ICU stay and improves the overall outcome. Nasogastric and orogastric tubes are the most commonly inserted feeding tubes. Breakage of an orogastric tube is a rare complication that can occur due to manufacturing defects, exposure to a harsh acidic environment, and forceful flushing of an obstructed tube.

Conclusions

Timely identification of the broken feeding tube can help the treating clinicians retrieve it easily even with the help of a laryngoscope in selected patients.

Severe hyponatremia as an atypical manifestation of pituitary macroadenoma: a case report

Pituitary macroadenoma most commonly presents with visual disturbances, headache, and other symptoms secondary to adeno hypophyseal hormonal deficiencies and usually alleviates after tumor resection. Pituitary adenomas may be the cause of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) causing hyponatremia, although so far, there have only been a few documented cases. Here, we present a case of pituitary macroadenoma with SIADH and hyponatremia. This case has been reported in line with CARE (CAse REport) criteria.

Case presentation

We present a case of a 45-year-old woman who presented with symptoms of lethargy, vomiting, altered sensorium, and seizure. Her initial sodium level was 107 mEq/l, plasma and urinary osmolality were 250 and 455 mOsm/kg, respectively, and her urine sodium level was 141 mEq/day, suggestive of hyponatremia due to SIADH. MRI scan of the brain revealed approximately 14×13×11 mm pituitary mass. Prolactin and cortisol levels were 41.1 ng/ml and 5.65 μg/dl, respectively.

Clinical discussion

Hyponatremia can result from various diseases, making it hard to identify the cause. A pituitary adenoma is a rare cause of hyponatremia due to SIADH.

Conclusion

Pituitary adenoma rarely might be the cause of SIADH presenting as severe hyponatremia. So, in case of hyponatremia due to SIADH, clinicians should keep pituitary adenoma as well in their differential diagnoses.

Wallerian degeneration in the brain after organophosphorus poisoning: a case report

The type, quantity, and potency of the organophosphorus compound (OPC) taken determine the symptoms of OPC poisoning as well as their severity. The exact etiology for organophosphorus (OP) poisoning delay neuropathy regulating Wallerian degeneration is still unknown.

Case Presentation

We report here a rare case of a 25-year-old lady with Wallerian degeneration in the brain found in an MRI in a patient after OPC ingestion. MRI of the brain, in our case, shows Wallerian degeneration of the corona radiata, internal capsule, and midbrain.

Clinical Discussion

Some OPCs can lead to OP-induced delayed neuropathy, a form of delayed neurotoxicity in humans (OPIDN). The distal axonopathy's (in OPIDN) morphological pattern resembles Wallerian degeneration, which happens in vitro following nerve damage. Although delayed Wallerian degeneration from organophosphate poisoning often affects the peripheral nervous system, it can also affect the central nervous system. Rehabilitation therapy combined with appropriate nursing care has been demonstrated to improve the disease.

Conclusion

Central nervous system involvement after OP poisoning is rare, and MRI of the brain and spinal cord can document evidence of Wallerian degeneration after OP poisoning.

Magnetic resonance imaging of the brain mimicking autoimmune encephalitis in sjogren syndrome with chorea: a case report

Neurologic manifestations in primary Sjögren syndrome (SS) range in prevalence from 8 to 49%, and most of the studies suggest a prevalence of 20%. The incidence of SS patients developing movement disorders is about 2%.

Case presentation

The authors herein report a case of a 40-year-old lady with MRI of the brain mimicking autoimmune encephalitis in SS who presented with chorea. Her MRI findings revealed T2 and FLAIR (fluid-attenuated inversion recovery) high signal intensity areas in bilateral middle cerebellar peduncles, dorsal pons, dorsal midbrain, hypothalami, and medial temporal lobes.

Clinical discussion

There is still no evidence to support the definite use of MRI in characterizing the central nervous system involvement in primary SS, especially due to overlapping findings with age and cerebrovascular disease. Multiple areas of increased signal intensity in periventricular and subcortical white matter in FLAIR and T2-weighted image is commonly seen in primary SS patients.

Conclusion

It is crucial to consider autoimmune diseases like SS as a cause of chorea in adults, even in those whose imaging findings are suggestive of autoimmune encephalitis.

Stiff person syndrome in a Nepalese man with uncontrolled diabetes mellitus and ketonuria: A rare case report

Stiff Person Syndrome (SPS), a progressive Central Nervous System disorder is accompanied by progressive muscle rigidity, hyperreflexia, and spasms mainly in truncal and proximal leg muscles mainly associated with autoimmune disorders. Here, we report a rare case of SPS in a middle-aged Nepalese man with uncontrolled diabetes mellitus and ketonuria.

Pembrolizumab-induced encephalitis in a patient with renal cell carcinoma post nephrectomy: A case report

A new category of immune-related adverse effects has been identified due to increasing use of immune checkpoint inhibitor therapy to treat solid organ cancers. Pembrolizumab approved for renal cell carcinoma also has neurological immune-related adverse effects causing long-term morbidity. We here present a case of renal cell carcinoma post nephrectomy with suspected pembrolizumab (anti-PD-1)-induced encephalitis presenting as light headedness and dizziness treated with high dose of corticosteroid and intravenous immunoglobulin. Lumbar puncture was performed which showed elevated protein, nucleated cells with lymphocyte predominant, suggestive of chemical meningitis. Scans were found to be normal while electroencephalogram showed diffuse cerebral dysfunction indicating encephalopathy. The patient was under pembrolizumab treatment so encephalitis was suspected. Clinical attention is necessary when patients receiving immune checkpoint inhibitors appear with new neurological symptoms to prevent long-term morbidity or even possible mortality.

Safety and efficacy of low-cost alternative urokinase in acute ischemic stroke: A systematic review and meta-analysis

INTRODUCTION

Use of intravenous thrombolysis (IVT) for treatment of acute ischemic stroke (AIS) varies greatly between countries, ranging from 10% to 15% in high-income countries to less than 2% in low- and middle income countries (LMICs). This is because alteplase is expensive and has been cited as one of the most common barriers to IVT in LMICs. Urokinase (UK) is a thrombolytic agent which is almost 50 times cheaper with easier production and purification than alteplase. UK may become a cost-effective option for IVT in LMICs if it is found to be safe and effective. We conducted this study to assess the existing evidence on the safety and efficacy of UK vs alteplase for IVT in AIS.

METHODS

The study was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and meta-Analyses) guideline. Systematic literature search was done in PubMed, EMBASE, and Google Scholar for English literature published from 2010 to 2021.

RESULTS

A total of 4061 participants in the alteplase and 2062 participants in the UK group were included in the final statistical analysis. After IVT, a good functional outcome at last follow-up was found among 80.57 % of patients in the alteplase group compared to 73.79 % of patients in the UK group (OR: 1.11; 95 % CI: 0.95- 1.31; I2 = 0 %; P = 0.18). Symptomatic Intracerebral Hemorrhage (sICH) was found among 1.77 % of patients in the alteplase group compared to 2.83 % of patients in the UK group (OR: 0.84; 95 % CI: 0.56- 1.26; I2 = 0 %; P = 0.41). Similarly, mortality was found among 5.03 % of patients in the alteplase group compared to 5.42 % of patients in the UK group (OR: 0.87; 95 % CI: 0.66-1.14; I2 = 0 %; P = 0.30).

CONCLUSION

Our meta-analysis found that intravenous UK is not inferior to alteplase in terms of safety and efficacy and can be a viable alternative for IVT in AIS patients in LMICs.

Levetiracetam versus Oxcarbazepine as monotherapy in newly diagnosed focal epilepsy: A systematic review and meta-analysis

OBJECTIVE

To compare the efficacy and safety of Levetiracetam (LEV) and Oxcarbazepine (OXC) as monotherapy for the treatment of newly diagnosed focal epilepsy.

METHODS

We searched PubMed, Cochrane Library, EMBASE, and Google Scholar from January 1, 2000 to May 11, 2022, with no language restrictions along with The ClinicalTrials.gov website and the WHO International Controlled Trials Registry platforms. We pooled the risk ratio (RR) and corresponding 95% confidence interval (95% CI) for the efficacy and safety outcomes. The quality of included trials was assessed using the Cochrane Collaboration's tool.

RESULTS

Two RCTs included a total of 574 newly diagnosed focal epilepsy patients (the LEV group [282 patients] and the OXC group [292 patients]). LEV group when compared with the OXC group had no significant difference in the pooled estimate of seizure freedom at week 24. (RR: 0.81; 95% CI: 0.62-1.05, p = .11). Similarly, there was no significant difference in the pooled estimate of withdrawal due to adverse events (AEs) (RR: 0.87; 95% CI: 0.34-2.23, p = .77). The commonly reported AEs in both trials were dizziness, headache, rash, somnolence, and nasopharyngitis with zero medication-related death and few serious AEs.

CONCLUSIONS

LEV is noninferior to OXC in terms of seizure freedom at week 24 and treatment withdrawal rate due to AEs among adults but long-term treatment data is still missing. Future multicentric double-blinded RCTs and real-world studies are of great need.

A rare incidental finding of an isolated S1 butterfly vertebra: A case report

Butterfly vertebra is an uncommon type of vertebral anomaly (sometimes referred to as a sagittal cleft vertebra or an anterior rachischisis) caused by persistent notochordal tissue. Butterfly vertebrae of S1, which is rarer anomaly compared to thoraco-lumbar region, may be associated with syndromic causes and usually asymptomatic with a funnel shaped defect seen in imaging which can later give rise to disk problems, facet joint degeneration and chronic low back pain. We here share a case of 35-year female presented with intermittent low back pain diagnosed with S1 butterfly vertebrae as an incidental finding in radiograph and magnetic resonance imaging. Radiologist and orthopedicians should be vigilant about this rare entity as a differential of low back pain and its association with other syndromes.

Safety and efficacy of endovascular thrombectomy in patients with severe cerebral venous thrombosis: A meta-analysis

Background

Cerebral venous thrombosis (CVT) is a rare thrombotic condition which is traditionally treated with anti-coagulation therapy. Subsets of patients with severe CVT have been treated with endovascular thrombectomy (EVT). Despite the high estimated mortality associated with severe CVT, there has been only one randomized control trial done regarding safety and efficacy of EVT in severe CVT compared to standard medical management. Evidence in this area is lacking.

Objective

The aim of this systematic review is to analyze all existing literature and generate robust information regarding the role of EVT in the management of patients with severe CVT.

Methods

This systematic review and meta-analysis followed PRISMA guideline. PubMed, Embase, Google Scholar, and CNKI were searched for eligible studies from 2007 to 2021. Safety and efficacy of EVT were evaluated by meta-analyzing recanalization status, the good functional outcome at follow-up, recurrent CVT, new hematoma. A pooled proportion with a 95% confidence interval was derived from a meta-analysis of various outcomes (CI).

Results

A total of 33 studies comprising 610 patients treated with EVT were included for analysis which comprised one randomized control trial, one prospective study and 31 retrospective studies. Based on pooled data, 85% of patients had good functional outcome, 62% had complete recanalization, 5% had all-cause mortality, and 3% had catheter related complications. The efficacy outcomes in this analysis had a significant heterogeneity and a subgroup analysis was also done to explain these findings. The minimum time of follow up was 3 months and varied EVT techniques were used across the studies.

Conclusion

This meta-analysis suggests EVT may be safe and efficacious in treating patients with severe CVT.

Registration

Our protocol was registered with PROSPERO: International prospective register of systematic reviews with the registration number CRD42021254760.

Clinical profile and management of perforation peritonitis in Bharatpur hospital, Nepal: A prospective study

Introduction

The most common surgical emergency in general surgery is perforation peritonitis. It is a serious condition with a mortality rate of up to 20%, and it is the third most common cause of surgical abdomen after appendicitis and intestinal obstruction. The aim of this study to discuss clinical profile and management of perforation peritonitis in a hospital in central Nepal.

Methods

This prospective study was done for one year at Bharatpur Hospital, Chitwan Nepal. In our study, only patient above 15 years were included and those who were not fit for anesthesia and surgery were excluded. Most of the patient were diagnosed clinically supported by lab investigations and imaging like X-ray and ultrasonography of abdomen. The variables analyzed were the risk factors of the patient like smoking, alcohol, liver disease and previous abdominal surgeries.

Results

The majority of the patients were in the age group 50–59 years in male and 40–49 years in female. Among sixty cases, 31 were female and 29 were male with Female: Male ratio of 1.06:1. The most common cause of perforation found was peptic ulcer compromising 88.3% (53 cases) followed by appendicular perforation accounting 8.3% (5 cases). Similarly, Tubercular perforation was found in 3.3%. Smoking was most common risk factor accounting 88.3%, followed by alcohol consumption (48.33%) while, 15% of patients had positive history of NSAIDs consumption. On imaging, 38.33% patient had air fluid level on X-ray and 78.33% had gas under diaphragm. On blood investigation, leukocytosis was found in 53.33% of patients, hyponatremia in 10% of patients and hypokalemia in 18.33% of patients. While on urine examination, albumin was found in 5% of patients. The repair of perforation along with omentopexy was done in 73.3% of patients while only repair was done in 15% of patients. Only 8.3% opted for appendectomy while a very few patients (3.3%) went for resection with anastomosis. The Postoperative complications found were wound infection (43.3%), paralytic ileus (18.33%), sepsis (15%), followed by electrolyte imbalance (11.6%), postoperative bowel obstruction (6.6%) and burst abdomen (1.6%). While, there were only 3 cases of mortality.

Conclusions

Perforation peritonitis is a frequently encountered surgical emergency. Various factors like age, sex, duration, site of perforation, extent of peritonitis and delay in surgical intervention are associated with morbidity and mortality. A successful management depends upon early surgical intervention, source control and exclusive intraoperative peritoneal lavage.

•

Perforation Peritonitis is a serious condition with a mortality rate of up to 20%.

•

Age, sex, duration, site of perforation, extent of peritonitis and delay in surgical intervention affect morbidity and mortality.

•

Early surgical intervention, source control and exclusive intraoperative peritoneal lavage are solutions.

Primary dedifferentiated liposarcoma of the breast: A case report

Primary breast liposarcoma is an extraordinarily rare breast malignancy. Histological subtypes including dedifferentiated are confirmed after a thorough histopathological and immunohistochemistry analysis. Liposarcoma of the breast can mimic other breast lesions. Long‐term follow‐up is needed due to the risk of local recurrence and delayed dedifferentiation.

Amyotrophic lateral sclerosis and retinal changes in optical coherence tomography: A systematic review and meta-analysis

INTRODUCTION

Increasing evidence suggests Amyotrophic Lateral Sclerosis (ALS) as a widespread pathological process comprising nonmotor features like fatigue, mild sensory symptoms, cognitive decline, and visual impairment. Measurements of retinal nerve fiber layer (RNFL) thickness using Optical Coherence Tomography (OCT) may correlate with the neurodegeneration associated with ALS. In addition to RNFL thickness, other OCT parameters have been explored in the context of diagnosing ALS and predicting disease severity. In this study, we explore the possibility that OCT parameters of patients with ALS may differ significantly from those of healthy controls and thus serve as biomarkers for the disease and its progression.

MATERIALS AND METHODS

Between 2010 and 2021, the PubMed and EMBASE databases were examined for English language literature. ALS severity was assessed using the revised ALS functional rating scale (ALSFRS-R). The pooled mean differences in RNFL thickness between ALS patients and controls were calculated using the Standard Mean Difference (Hedges's g) with a 95% confidence interval (CI) in STATA software version 16.

RESULTS

Eleven studies were reviewed for data collection. RNFL thickness was not statistically significantly different between ALS patients (n = 412) and controls (n = 376) (Hedges's g = -0.22; 95% CI: -0.51 to 0.07, I² = 73.04%, p = .14). However, the thickness of inner nuclear layer was significantly different between ALS patients and controls (Hedges's g = -0.38; 95% CI: -0.61 to 0.14, I² = 14.85%, p = .00).

CONCLUSION

Our meta-analysis found that RNFL thickness as a whole or by individual quadrants was not significantly different between ALS patients and controls while the inner nuclear layer (INL) was substantially thinner.

Low-dose alteplase for the management of acute ischemic stroke in South Asians: A systematic review on cost, efficacy and safety

INTRODUCTION

South Asia is responsible for more than 40% of the stroke burden and stroke mortality in the developing world. South Asia, which is home to one-fourth of the world's population, is the most densely populated and one of the poorest regions. The majority of patients in this region are unable to afford intravenous thrombolysis (IVT) for acute ischemic stroke (AIS). If low-dose alteplase proves effective and safe in South Asians, it may be a more cost-effective treatment option.

METHODS

The study was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and meta-Analyses) guideline. Researchers searched PubMed, EMBASE, and Google Scholar for English literature from 2005 to 2021. END, ENI, good functional outcome, SICH, and all-cause mortality were used to assess efficacy and safety.

RESULTS

In the low-dose alteplase treated patients, different studies reported 32 to 57% ENI 24 h after IVT, and 7% to 9.7% END. At 3 months follow-up, good functional outcome was achieved by 48%-76.92% of low-dose alteplase treated patients. SICH rates ranged from 0% to 16.6% across studies. Asymptomatic ICH occurred in 5-14% of patients. The mortality rate in all included studies varied from none to 25%.

CONCLUSION

Our systematic review demonstrates that the use of low-dose alteplase for AIS in the South Asians offer comparable efficacy and reduced risk of SICH at a significantly lower cost than standard alteplase dose. Future well-randomized clinical trials are necessary to validate the findings of our study.

Giant ovarian mucinous cystadenocarcinoma: A case report

Giant ovarian tumors are rare in the present day due to the early diagnosis and treatment. However, owing to the large size, it can often compress the inferior vena cava and sudden decompression of it during the removal can lead to hemodynamic instability with disastrous outcomes.

Evaluation of portal venous system in post splenectomised beta-thalassemic children: A prospective study in a tertiary care hospital

Background

Splenectomy is a palliative management technique in children with β-thalassemia. Portal thrombosis is the most dreaded complication after splenectomy that requires fast diagnosis, effective therapy, and good follow-up to prevent protal hypertension. Thus, there is the importance of constant evaluation of portal venous system through Color Doppler Ultrasound. This cohort study aimed to observe the changes in the portal venous system in post-splenectomised β-thalassemic children.

Material and methods

This is a prospective observational cohort study carried out on all the pediatric patients who have undergone splenectomy in Bangabandhu Sheikh Mujib Medical University, Dhaka Bangladesh from 2017 to 2019 for β-thalassemia. The color doppler of the portal venous system was done within the 7th to 10th post-operative day and after 3 months. Outcomes like mean the caliber of the portal vein, mean velocity within the portal vein, and color Doppler findings like Portal Vein Thrombosis (PVT) and Pathological change in Mean Volume (PMV) were calculated and compared in two headings: pre-operative period and postoperative period (7–10 POD and 3 months) with the help of paired t-test.

Results

Twenty-Eight β-thalassemia patients with a mean age of 10.43 ± 3.91 years planned to undergo splenectomy were included in our study. The pre-operative mean caliber and mean velocity of the portal vein were not statistically significant when compared after the postoperative period (7–10 POD and 3 months). But, continuous changes in portal vein were seen that could lead to normalization or pathological changes.

Conclusion

There are physiological and pathological changes in portal vein following splenectomy that could lead to varied complications like portal vein thrombosis and portal hypertension. Color Doppler Ultrasound findings along with close follow-up help in minimizing the pathological changes and complications.

•

Splenectomy is a palliative management technique in children with β-thalassemia.

•

Portal vein thrombosis and portal hypertension are dreaded complications.

Risk factors for recurrent intussusception after successful reduction in pediatric patients in a tertiary care hospital of Nepal: A prospective study

Background

Intussusception is defined as the invagination of one segment of intestine into another segment of intestine. It may recur because of persistence or return of some factor responsible for the primary intussusception. Various risk factors have been reported but still not well elucidated.

Materials and methods

This is the prospective observational study. In this study, 78 patients, age <16 years with diagnosis of intussusception between June 2019 and April 2020 who had successful reduction with either hydrostatic reduction and/or operative reduction in Teaching Hospital were enrolled in the study. This is study of early recurrence as patients were followed up to a period of 1 month for recurrence of intussusception. The recurrent cases were thus identified and various variables were compared between recurrent and non-recurrent cases by univariable and multivariable analysis.

Results

Among 78 patients, 13 patients (16.7%) had recurrent intussusception. In the univariable analysis model, the significant risk factors for recurrence of intussusception analyzed were duration of symptoms of 48 h or more, fever, blood in stool and palpable mass. While after multivariable analysis, we found that the significant risk factors for recurrence of intussusception were duration of symptoms ≥48 h (OR = 5.32, p-value = 0.047), Fever (OR = 17.32, p-value = 0.001), palpable mass (OR = 24.12, p-value = 0.017).

Conclusion

Attention and awareness among pediatricians about these sonographic and clinical risk factors especially symptoms for recurrence are needed to minimize pre-hospital delay and identify patients in risk of recurrence. This ultimately helps to improve care for pediatric patients with recurrent intussusception.

•

Intussusception is a common abdominal emergency in infancy and childhood.

•

Definitive or reliable risk factors for recurrence, other than anatomical features, have not been well elucidated.

•

Duration of symptoms >24 h, fever and palpable mass are the risk factors.

Prognostic significance of mean platelet volume in patients with lung cancer: a meta-analysis

OBJECTIVE

The mean platelet volume (MPV) is a measure of platelet size, and it is considered a surrogate marker of platelet activation. Because the correlation between platelet count/size and lung cancer prognosis remains unclear, this meta-analysis comprehensively evaluated the prognostic significance of MPV among patients with lung cancer.

METHODS

A systematic search of PubMed, Embase, Google Scholar, and additional sources of relevant studies were conducted with no language restrictions from inception to 7 May 2021. Overall survival (OS) and disease-free survival (DFS)/progression-free survival (PFS), as well as their hazard ratios (HR) and 95% confidence intervals (CIs), were pooled to evaluate the relationship between MPV and survival. The study protocol was registered on PROSPERO.

RESULTS

Eleven studies involving 2421 patients with lung cancer were included in our analysis. Nine studies including only patients with non-small cell lung cancer were included in the meta-analysis. Our analysis revealed no significant associations of MPV with OS (HR = 1.09, 95% CI = 0.84-1.41) and DFS/PFS (HR = 1.13, 95% CI = 0.58-2.20).

CONCLUSION

Pretreatment MPV levels did not display prognostic significance in patients with NSCLC. Large-scale prospective studies and a validation study considering ethnicity and lung cancer staging are warranted.

C-reactive protein levels in patients with amyotrophic lateral sclerosis: A systematic review

INTRODUCTION

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting cortical and spinal motor neurons. There is a lack of optimal biomarkers to diagnose and prognosticate the ALS patients. C-reactive protein (CRP), an inflammatory marker, has shown promising results in ALS patients.

MATERIALS AND METHODS

PubMed, Embase, and Google Scholar databases were searched from 2000 to June 1, 2021 for suitable studies showing the relationship between CRP and ALS. The concentration of CRP levels was assessed between ALS patients and controls. Further, end outcomes like ALS functional rating scale (ALSFRS-R), survival status, and mortality risks were assessed in relation to CRP levels.

RESULTS

Eleven studies including five case-control, five cohorts, and one randomized control study were assessed. There were 2785 ALS patients and 3446 healthy controls. A significant increment in CRP levels among ALS patients in comparison with healthy controls were seen in most of the studies. ALSFRS-R and disease progression were found to be significantly correlated with CRP levels. Overall accuracy of CRP in CSF was 62% described in a single study.

CONCLUSION

Although CRP has shown promise as a prognostic biomarker, extensive cohort studies are required to assess its prognostic value and accuracy in diagnosing ALS taking into account the confounding factors.

Clinical spectrum and management of dystonia in patients with Japanese encephalitis: A systematic review

BACKGROUND

Japanese encephalitis (JE) is a potentially fatal viral infection with a wide range of manifestations and can also present with a variety of movement disorders (MD) including dystonia. Dystonic features in JE are uncommon. Here, we have tried to summarize the clinical features and management of dystonia among JE patients with a comprehensive literature search.

METHODS

Various databases, including PubMed, Embase, and Google Scholar, were searched against the predefined criteria using suitable keywords combination and boolean operations. Relevant information from observational and case studies was extracted according to the author, dystonic features, radiological changes in the brain scans, treatment options, and outcome wherever provided.

RESULT

We identified 19 studies with a total of 1547 JE patients, the diagnosis of which was confirmed by IgM detection in serum and/or cerebrospinal fluid in the majority of the patients (88.62%). 234 (15.13%) of JE patients had dystonia with several types of focal dystonia being present in 131 (55.98%) either alone or in combination. Neuroimaging showed predominant involvement of thalami, basal ganglia, and brainstem. Oral medications including anticholinergics, GABA agonists, and benzodiazepines followed by botulinum toxin were the most common treatment modalities.

CONCLUSION

Dystonia can be a disabling consequence of JE, and various available medical therapies can significantly improve the quality of life. Owing to insufficient studies on the assessment of dystonia associated with JE, longitudinal studies with a larger number of patients are warranted to further clarify the clinical course, treatment, and outcome of dystonia.

BRCA1/BRCA2 mutation spectrum analysis in South Asia: a systematic review

Objective

Breast cancer (BC) is the most common form of cancer among Asian females. Mutations in the BRCA1/BRCA2 genes are often observed in BC cases and largely increase the lifetime risk of having BC. Because of the paucity of high-quality data on the molecular spectrum of BRCA mutations in South Asian populations, we aimed to explore these mutations among South Asian countries.

Methods

A systematic literature search was performed for the BRCA1 and BRCA2 gene mutation spectrum using electronic databases such as PubMed, EMBASE, and Google Scholar. Twenty studies were selected based on specific inclusion and exclusion criteria.

Results

The 185delAG (c.68_69del) mutation in exon 2 of BRCA1 was the most common recurrent mutation and founder mutation found. Various intronic variants, variants of unknown significance, large genomic rearrangements, and polymorphisms were also described in some studies.

Conclusions

The South Asian population has a wide variety of genetic mutations of BRCA1 and BRCA2 that differ according to countries and ethnicities. A stronger knowledge of various population-specific mutations in these cancer susceptibility genes can help provide efficient strategies for genetic testing.

Metastatic ovarian carcinoma in breast cancer patients during risk-reducing salpingo-oophorectomy: Report of two cases

INTRODUCTION AND IMPORTANCE

Metastatic ovarian cancer of breast carcinoma is rare and accounts for only 0.68%-2% of all ovarian tumors, the majority of which are diagnosed incidentally during follow-up or therapeutic oophorectomy. Risk-reducing salpingo-oophorectomy (RRSO) is a highly recommended prophylactic surgery associated with a significant decrease in ovarian cancer risk in both BRCA1 and BRCA2 mutation carriers, and in those with and without prior breast cancer.

CASE PRESENTATION

We present two cases who presented with a lump in the right axilla and left breast respectively and were subsequently diagnosed as invasive mammary carcinoma but later, diagnosed with metastatic ovarian carcinoma with breast primary after RRSO. The patients were treated with cycles of chemo-radiation.

DISCUSSION

Invasive lobular carcinoma, larger tumor size, advanced breast cancer increases the risk of developing ovarian metastases. Thorough macroscopic, microscopic, immunohistochemical, and molecular tests are considered the cornerstone in the diagnosis of metastatic breast cancer to the ovaries. Bilateral salpingo-oophorectomy, a risk-reducing surgery for the BRCA gene mutation, has been shown to reduce the risk of death from ovarian cancer.

CONCLUSIONS

Metastatic ovarian cancer in breast cancer is a rare possibility among patients undergoing RRSO for breast cancer. The importance of continued surveillance of ovaries rather than the delayed diagnosis of ovarian metastasis for patients with newly diagnosed breast cancer cannot be less emphasized.

Safety and efficacy of Direct Oral Anticoagulants in cerebral venous thrombosis: A meta-analysis

Cerebral venous thrombosis (CVT) is caused by partial or complete occlusion of the major cerebral venous sinuses or the smaller feeding cortical veins which predispose to the risk of venous infarction and hemorrhage. Current guidelines recommend treating CVT with either low-molecular-weight heparin (LMWH) or unfractionated heparin (UFH) followed by an oral vitamin K antagonist (VKA) for 3-12 months. Direct oral anticoagulants (DOACs) have already established benefit over warfarin as a long-term treatment of symptomatic venous thromboembolic disorder like deep vein thrombosis (DVT), and pulmonary embolism (PE) given its equal efficacy and better safety profile. The benefit of DOACs over warfarin as a long-term anticoagulation for CVT has likewise been extensively studied, yet it has not been approved as first-line therapy in the current practice. We therefore performed a systematic review and meta-analysis of relevant studies to generate robust evidence regarding the safety and efficacy of DOACs in CVT. This meta-analysis demonstrates that the use of DOACs in CVT has similar efficacy and safety compared to VKAs with better recanalization rate.

Clinical Manifestations, Neuroimaging Findings, and Treatment of Idiopathic Intracranial Hypertension in a Nepalese Tertiary Centre

Introduction: Idiopathic Intracranial Hypertension is characterized by headache, visual impairment, papilledema, and increased cerebrospinal fluid opening pressure. We aim to evaluate clinical manifestations, neuroimaging findings, and treatment of Idiopathic Intracranial Hypertension in a Nepalese tertiary center. Materials and Methods: We retrospectively included patients with the diagnosis of Idiopathic Intracranial Hypertension who were admitted to the Neurology department of Tribhuvan University Teaching Hospital from 2019 June to 2021 May and presented to the Neuro-ophthalmology outpatient clinic of the hospital for follow-up. Results: Out of 16 Idiopathic Intracranial Hypertension patients, 12(75%) patients had either headache or ocular pain.  Reduced visual acuity and progressive visual loss were found in 44% of patients. Normal CSF opening pressure was found in 19%, 44% had CSF opening pressure at a range of 20-30 cm H20 and > 30 cm H20 in 37.5%. 15 Idiopathic Intracranial Hypertension patients (93.7%) were subtyped as Typical and 1 patient was diagnosed as Fulminant Idiopathic Intracranial Hypertension. Acetazolamide was used for treatment in 15 patients and 1 patient needed ventriculoperitoneal shunting. 56% Seven patients (44%) had some abnormal findings: partial empty sella (44%), and tortuous optic nerve (31%), flattened posterior eyeball (31%), and hypoplastic transverse sinus (19%). Conclusions: Idiopathic Intracranial Hypertension is an uncommon diagnosis but should be suspected in patients with chronic headaches with visual impairment. In low-resource settings, proper history along with neurological and ophthalmological examinations can even detect the early features and timely referral can save the vision and disability of Idiopathic Intracranial Hypertension patients.

Safety and efficacy of interleukin-6-receptor inhibitors in the treatment of neuromyelitis optica spectrum disorders: a meta-analysis

BACKGROUND

Interleukin-6-receptor inhibitors like Tocilizumab and Satralizumab are showing promising results in the treatment of Neuromyelitis Optica spectrum disorder (NMOSD). We aimed to investigate the efficacy and safety of various Interleukin-6-receptor inhibitors in the management of NMO/NMOSD.

METHODS

PubMed, Embase, and The Cochrane Library were systematically searched for suitable studies. Change in Annualized Relapse Ratio (ARR), Change in Extended Disability Status Scale (EDSS) s, the proportion of relapse-free patients and proportion of patients with adverse events, including serious adverse events and mortality were the parameters considered for the meta-analysis for Tocilizumab. Mean difference (MD) with 95% CI was used to quantify the change in ARR and change in EDSS before and after treatment. A forest plot was prepared to indicate the efficacy and adverse effects outcomes. The results were compared with those of Satralizumab included in two trials.

RESULTS

A total of nine studies with 202 patients were included in our study. Tocilizumab found a good proportion (76.95% CI: 0.61-0.91; p < 0.001) of relapse free patients at follow up. It also significantly reduced mean ARR (mean difference: -2.6, 95% CI: - 2.71 to - 1.68; p < 0.001) and but did not show significant difference in change in EDSS score (mean difference = - 0.79, 95% CI: - 1.89 to - 0.31; p = 0.16). Also, the toxicity profile of Tocilizumab was acceptable considering the proportions of patients with adverse events 56% (95% C.I.;0.27-0.85, I2 = 88.95%, p < 0.001), proportions of patients with serious adverse events 11% (95% C.I.; 0.05 to 0.17, I2 = 0%, p < 0.001) and zero treatment related deaths. SAkura studies for Satralizumab showed similar relapse free patients (70% to 80%) and reduction of ARR and EDSS from baseline. Some studies of Tocilizumab have shown to reduce pain and fatigue while trials of Satralizumab had non-significant findings.

CONCLUSION

Interleukin-6-receptor inhibitors therapy showed a promising result with good efficacy and acceptable adverse events profile for treatment of NMOSD.

High drug resistance among Gram-negative bacteria in sputum samples from an intensive care unit in Nepal

SETTING

Tribhuvan University Teaching Hospital, Kathmandu, Nepal.

OBJECTIVES

1) To report the number and proportion of Pseudomonas, Acinetobacter, Burkholderia, Stenotrophomonas (PABS) species among intensive care unit (ICU) patients with sputum culture; and 2) to assess antimicrobial resistance patterns, demographic and clinical characteristics associated with resistance to at least one antibiotic and ICU discharge outcomes among those patients with PABS species admitted to hospital between 14 April 2018 and 13 April 2019.

DESIGN

This was a hospital-based, cross-sectional study using secondary data.

RESULTS

Of 166 who underwent sputum culture, 104 (63%) had bacterial growth, of which, 67 (64%) showed PABS species. Of the positive cultures, Pseudomonas, Acinetobacter, Burkholderia and Stenotrophomonas were present in respectively 32 (30.7%), 31 (29.8%), 1 (1%) and 3 (2.8%). Pseudomonas showed a high level of resistance to levofloxacin (61%), cefepime (50%) and amikacin (50%). Acinetobacter was largely resistant to cefepime (95%), imipenem (92%) and levofloxacin (86%). Of the 67 with PABS infection, 32 (48%) died.

CONCLUSION

The study showed a high prevalence of Pseudomonas and Acinetobacter and the emergence of Stenotrophomonas in sputum culture samples of ICU patients. This highlights the need for monitoring PABS and associated resistance patterns to reduce mortality in ICU patients.

Paget's disease of nipple with dermal invasion: A case report

Background

Invasive mammary Paget's disease (MPD) is an extremely rare eczematous eruption on the nipple and areola with an invasion of the dermis by Paget cells. This entity can often be misdiagnosed and overtreated for invasive carcinoma of the breast.

Case

A 34‐year woman presented with a 2‐year history of right nipple eczema and right axillary lump for a month. Breast ultrasound revealed dilated intra‐nipple lactiferous duct and an enlarged right axillary lymph node. Histopathology from biopsy revealed MPD with ductal carcinoma in situ (DCIS) whereas final histopathology after right modified radical mastectomy revealed Invasive MPD with DCIS and axillary metastasis. She underwent adjuvant chemotherapy and is under hormonal therapy with complete remission for 18 months.

Conclusion

Awareness of invasive MPD is important to avoid misdiagnosis and probable radical treatment. Close follow‐up is warranted due to limited knowledge regarding treatment and prognosis of invasive MPD.

Safety and efficacy of Magnesium Sulfate in the management of Tetanus: A systematic review

Tetanus is a rare life-threatening condition often complicated by repetitive spasms, dysautonomia and neuromuscular respiratory failure contributing to high fatality rates in its severe form. Benzodiazepines used to treat muscle spasms pose a high risk of respiratory failure requiring mechanical ventilation, which is unaffordable and inaccessible for many. Magnesium sulfate, a cheap and widely available medication in all urban and rural health centres of LMICs for the treatment of eclampsia, can be used to control muscle spasms and dysautonomia. We thus conducted a systematic review of evidence to assess the safety and efficacy of magnesium sulfate in the treatment of tetanus. Any study published before April 15, 2021, discussing the efficacy and/or safety of MgSO4 infusion in the treatment of tetanus was systemically reviewed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Our systematic review included data from 13 studies, three were randomised, double-blind and controlled trials. The remaining ten studies were observational; six prospective and four retrospective studies. Our review showed no mortality benefit associated with the use of magnesium sulfate. However, magnesium sulfate was found to be effective in reducing spasms along with diazepam, leading to better control of dysautonomia, reduced need for mechanical ventilation and shorter hospital stay by 3-7 days. The incidence of magnesium toxicity was very low in the studies included.

Heterotaxy syndrome with complex congenital heart disease, facial palsy, and asplenia: A rare newborn finding

Heterotaxy syndrome is associated with asplenia/polysplenia and complex congenital heart disease. Facial palsy in heterotaxy is very rare. The management is still challenging with a poor prognosis. Proper counseling to the family about the disease course, treatment modalities, and outcomes is essential.

Incidental finding of Langerhans cell histiocytosis of temporoparietal bone - A case report

Introduction and importance

Langerhans cell histiocytosis (LCH) is a rare haematological disorder affecting infants and young children and has an estimated incidence of 2-5 cases per million people per year. LCH invades the reticuloendothelial system and causes the proliferation of Langerhans cells and mature eosinophils. LCH involving the temporoparietal bone has rarely been reported in the literature.

Presentation of case

A ten-year-old boy presented to the Neurosurgical outpatient clinic with a swelling on the right temporoparietal region following a fall from his bicycle. Local examination revealed a single, 3 × 3 cm, non-tender, cystic, immobile swelling in the right temporoparietal region. On evaluation for recent head trauma, an incidental finding of eosinophilic granuloma was discovered on a CT scan. The FNAC was suggestive of a histiocytic lesion pertaining to a diagnosis of LCH. The patient underwent wide excision of the mass and cranioplasty. A one-month follow-up CT scan of the head had no evidence of residual or recurrent disease.

Discussion

Eosinophilic granuloma is one of the three variants of LCH and has a relatively better prognosis. Clinical diagnosis can be challenging and mandates tissue sampling for histopathological examination. Treatment modalities including surgery, radiotherapy, chemotherapy, and steroid injection are used alone, or in combination, depending on the extent and severity of the disease.

Conclusion

Examining a swelling in the temporoparietal region with no other characteristic symptoms could be a case of LCH. The timely diagnosis and surgical excision with other adjuvant treatment options of this rare pediatric disease would help in a better outcome.

•

Langerhans cell histiocytosis can present as a mass in the temporal or parietal region with no symptoms otherwise.

•

The etiology of Langerhans cell histiocytosis is still unknown and diagnosis can be challenging.

•

The prognosis depends greatly on early identification and prompt surgical treatment.

Multiple jejunal gastrointestinal stromal tumors and Neurofibromatosis type 1: A rare association

INTRODUCTION AND IMPORTANCE

The association between gastrointestinal stromal tumor (GIST), mesenchymal tumor arising from the interstitial cells of cajal and Neurofibromatosis type 1 (NF1), an autosomal dominant disease has been reported in the literature. GIST in NF1 patients are multiple and located in the small intestine. Tumorigenesis in NF1 associated GIST is different to that of sporadic GIST and hence the treatment. Here we report a rare case of an NF1 patient with multiple jejunal GISTs.

CASE PRESENTATION

We here present a rare case of a 57-year-old male diagnosed with NF1 30 years back, presented in our emergency department with complaints of black, tarry stools later diagnosed to have multiple GIST in jejunum. Contrast enhanced computed tomography (CECT) of the abdomen showed a large 10.1 × 7.33 × 6.2 cm heterogeneous, exophytic, solid mass with cystic areas originating from the jejunum. The microscopic examination of the specimen showed spindle shaped tumor cells while immunohistochemistry showed CD117 (c-KIT) and DOG-1 positivity. The primary treatment was complete surgical excision of the tumor.

CLINICAL DISCUSSION

The incidence of GISTs in NF1 patient is around 6-7%; however, concomitant presence of multiple GISTs is rare. CECT of abdomen along with histopathological and immunohistochemistry studies are diagnostic. The management of GIST includes surgical and adjuvant therapy methods based on the tumorigenesis and recurrent risk stratification.

CONCLUSION

Early clinical suspicion and imaging aids in early detection of the tumor in patients with NF1 presenting with gastrointestinal symptoms. Postoperatively, screening for recurrence with radiology is of utmost importance.

Hirschsprung disease with Edward syndrome: A rare association: A case report

INTRODUCTION AND IMPORTANCE

Edward's syndrome (ES) occurs as a result of trisomy of chromosome 18 and is associated with multisystem congenital anomalies. The association of ES with various gastrointestinal malformations but Hirschsprung disease (HD) is well documented.

CASE PRESENTATION

A female infant on her 5th day of life presented with episodes of bilious vomiting along with abdominal distension and no passage of stool. The child had a small head and prominent occiput, low set abnormal ears, small jaw, upturned nose, widely spaced eyes, small neck with widely spaced nipples, clenched hands with overlapping fingers, flexed big toe, and prominent heels.

CLINICAL DISCUSSION

Edward syndrome is associated with multisystem congenital abnormalities of which gastrointestinal abnormalities make up the most part. The condition can be identified by fetal ultrasound screening. Surgical correction of associated congenital anomalies at different times along with lifelong supportive management is important.

CONCLUSIONS

Edward syndrome can present as Hirschsprung disease as a part of associated gastrointestinal Malformation. Often, early identification and termination of the pregnancy in antenatal life can reduce the suffering. Surgical correction of associated anomalies along with supportive care forms the cornerstone of management. However, the prognosis remains poor.

Cecal gastrointestinal stromal tumor causing ileocolic intussusception in an adult: A rare case report

Introduction and importance

Cecal gastrointestinal stromal tumors (GIST) constitute a rarer subtype of all GISTs. Rarely, it can present with ileocolic intussusception in adults making it a challenging diagnosis due to non-specific clinical features.

Case presentation

A 30-year previously healthy woman presented with lower abdominal pain and a distended abdomen who was subsequently diagnosed with ileocolic intussusception on a CT scan. Intraoperatively, a pedunculated polypoid hard mass was identified in the cecum and thus, a standard right hemicolectomy was performed with the suspicion of malignancy. Histopathology of the resected mass confirmed CD117 negative, spindle type GIST.

Discussion

Cecal GIST presenting in the form of ileocolic intussusception is rare. Contrast-enhanced CT scan is the preferred imaging modality for the evaluation of patients with suspected GIST to determine the extent of the tumor, the presence or absence of metastatic disease alongside evaluation of the possibility of complete resection. Adjuvant imatinib therapy following complete resection decreases the disease recurrence.

Conclusion

Intussusception in an adult can be the first manifestation of underlying malignancy like GIST. Complete surgical resection of the tumor with a negative margin offers long-term survival.

•

Ileocolic intussusception is rare in adult and often associated with pathological lead points like neoplasm.

•

Cecal GIST is an uncommon cause of ileocolic intussusception in adults.

•

Diagnosis of this entity is challenging because of its non-specific presenting features.

Adrenal schwannoma: A case report of an unusual incidentaloma

Introduction and importance

Adrenal schwannomas are extremely rare tumors often misdiagnosed. The patients are usually asymptomatic while some present with non-specific abdominal pain. Only a few cases are reported to date.

Case presentation

We here present a case of a 55-year-old Nepalese man presented with nonspecific abdominal pain at our Outpatient Department (OPD) found to have mass on ultrasonography of abdomen. On further investigation with Contrast Enhanced Computerized Tomography (CECT) of the abdomen and pelvis, a well-defined heterogeneous adrenal mass of size (7.8 ∗ 8.3 ∗ 6) cm with foci of calcification was seen in the left retroperitoneum. The intraoperative finding of adrenal mass and histopathology of resected mass was suggestive of schwannoma arising from the adrenal gland which was further confirmed by immunohistochemistry.

Clinical discussion

Adrenal schwannoma can mimic tumors like pheochromocytoma, adrenal adenoma, cortical carcinoma, neuroblastoma, and other masses. Only 1–3% of schwannomas are retroperitoneal. Radiological findings of this tumor are non-suggestive. The histological section shows spindle cells with Antoni A and Antoni B regions while positive staining of S-100 protein in Immunohistochemistry.

Conclusion

The diagnosis of adrenal schwannoma in the retroperitoneum is often challenging. The treatment of choice is surgical resection with a good prognosis.

•

Adrenal schwannomas are extremely rare tumors.

•

These tumors are mostly found incidentally and often asymptomatic.

•

Complete surgical resection of the tumor is a must for good prognosis.

Jejunal varices with extra hepatic portal vein obstruction: A case report

Introduction and importance

Extrahepatic portal vein obstruction (EHPVO) with portal hypertension is rare in children. Intestinal varices as new collaterals accompanying portal hypertension are very rare.

Presentation of case

We report an unusual case of a 12-year-old boy with EHPVO with gastrointestinal bleeding from ectopic jejunal varices, without any gastroesophageal varices.

Discussion

Portal hypertension is the most common cause of EHPVO. Among various ectopic varices, intestinal varices are found distal to the duodenum and present with complaints of hematochezia, melena, or intraperitoneal bleeding. The diagnosis of the EHPVO is aided by imaging investigations like Doppler ultrasound, computed tomography, or magnetic resonance imaging. A multidisciplinary team including gastroenterologists, interventional radiologists, surgeons, and intensivists is crucial in the management of ectopic varices.

Conclusion

Jejunal varices must be considered in the differential diagnosis of gastrointestinal (GI) hemorrhage in patients with a negative source of bleed on upper and lower GI endoscopy.

•

Intestinal varices are rarely developed as new collaterals accompanying portal hypertension with EHPVO (Extrahepatic portal vein obstruction).

•

Jejunal varices must be considered in patients with a negative source of bleed on upper and lower GI endoscopy.

Primary squamous cell carcinoma of the breast in a young female- A rare ailment

Primary squamous cell carcinoma of the breast is an extremely rare invasive breast carcinoma with rapid progression and worse prognosis. Careful assessment and diagnosis of the entity should also be considered in a rapidly progressing breast tumor.

Common hepatic artery pseudoaneurysm: A rare complication following total gastrectomy: A case report

•

Common Hepatic Artery pseudoaneurysm after total gastrectomy is uncommon and can be devastating.

•

We report a case of a ruptured common hepatic artery pseudoaneurysm who presented with massive gastrointestinal bleeding.

•

Early assessment with CT angiography followed by early appropriate treatment is life-saving.

Introduction and importance

Common Hepatic Artery (CHA) Pseudoaneurysm is a rare entity, attributed to infections, trauma, and upper abdominal surgery. Most cases occur after biliary and pancreatic surgery. CHA pseudoaneurysm after total gastrectomy is uncommon and can be devastating.

Case presentation

A 58-years male who underwent D2 total gastrectomy for gastric carcinoma ten days ago, presented with hematemesis, epigastric pain, and a history of melaena. After admission, upper gastrointestinal endoscopy showed a clot at the jejunojejunostomy site. Computed tomography with angiography was diagnostic of pseudoaneurysm of CHA located inferiorly. Coil embolization of CHA was done and the patient improved.

Clinical discussion

Pseudoaneurysm of the common hepatic artery is a serious complication after abdominal surgery. Only a few cases have been reported with similar symptoms related to gastrointestinal bleeding following various upper abdominal surgeries. Coil embolization is a gold standard technique with a high success rate.

Conclusion

CHA pseudoaneurysm is a dreadful potential complication of abdominal surgery including gastrectomy. Early recognition and emergency management of CHA pseudoaneurysm are crucial for a favorable outcome for patients with bleeding from CHA aneurysm.

Ventilator-associated pneumonia among ICU patients in WHO Southeast Asian region: A systematic review

Ventilator-associated pneumonia (VAP) is one of the most frequent ICU-acquired infections and a leading cause of death among patients in Intensive Care Unit (ICU). The South East Asian Region is a part of the world with limited health resources where infectious diseases are still underestimated. We aimed to review the literature in this part of the world to describe incidence, mortality and microbiological evidence of VAP and explore preventive and control strategies. We selected 24 peer-reviewed articles published from January 1, 2000 to September 1, 2020 from electronic databases and manual searching for observational studies among adult patients diagnosed with VAP expressed per thousand days admitted in ICU. The VAP rates ranged from 2.13 to 116 per thousand days, varying among different countries of this region. A significant rate of mortality was observed in 13 studies ranging from 16.2% to 74.1%. Gram negative organisms like Acinetobacter spp., Pseudomonas aeruginosa and Klebsiella pneumoniae and Gram-positive organisms like Staphylococcus aureus and Enterococcus species were frequently found. Our findings suggest an alarming situation of VAP among patients of most of the countries of this region with increasing incidence, mortality and antibiotic resistance. Thus, there is an urgent need for cost effective control and preventive measures like interventional studies and educational programs on staff training, hand hygiene, awareness on antibiotic resistance, implementation of antibiotic stewardship programs and appropriate use of ventilator bundle approach.

Prevalence of vancomycin-resistant enterococci in Asia-A systematic review and meta-analysis

WHAT IS KNOWN AND OBJECTIVE

The rise of vancomycin-resistant enterococci (VRE) has been a major health problem in most countries of the world including Asia, since its discovery. There is a paucity of data on VRE in many countries of Asia as well as limited pooled estimates. Therefore, we performed a systematic review and meta-analysis to estimate a pooled prevalence of VRE in Asia.

METHODS

A literature search in electronic databases like PubMed, Embase and Google Scholar and manual searching of references and grey literature, comprising the information on the prevalence of VRE with at least two species of enterococci, conducted in different countries of Asia from January 1, 2000, to September 20, 2020, was done. The random-effect model and 95% CIs was used to calculate the pooled prevalence. Subgroup, sensitivity and meta-regression analyses were performed to address heterogeneity while Egger's test for publication bias.

RESULTS AND DISCUSSIONS

We identified 39 studies, comprising a total of 11,875 enterococcal isolates. The result of the analysis showed that the pooled prevalence of VRE in Asia was 8.10% (95% CI; 7-9; I²  = 93.79%; p < 0.001). Resistance to vancomycin was greater among strains of E. faecium compared to the strains of E. faecalis (22.40% vs. 3.70%). Amongst various regions of Asia, the highest prevalence of VRE was found in the Western Asian region and the lowest in the South-east Asian region. Moreover, the rate of VRE was higher than most European countries and lower than USA.

WHAT IS NEW AND CONCLUSIONS

With an upsurge of VRE in Asia in recent years, efficient infection control programmes, robust surveillance systems and adherence to antibiotic stewardship are paramount to halt the further rise of VRE.
