Stroke epidemiology and outcomes of stroke patients in Nepal: a systematic review and meta-analysis.

BACKGROUND: With an increasing burden of stroke, it is essential to minimize the incidence of stroke and improve stroke care by emphasizing areas that bring out the maximum impact. The care situation remains unclear in the absence of a national stroke care registry and a lack of structured hospital-based data monitoring. We conducted this systematic review and meta-analysis to assess the status of stroke care in Nepal and identify areas that need dedicated improvement in stroke care. METHODS: A systematic literature review was conducted to identify all studies on stroke epidemiology or stroke care published between 2000 and 2020 in Nepal. Data analysis was done with Statistical Package for Social Sciences (SPSS) and Comprehensive Meta-analysis (CMA-3). RESULTS: We identified 2533 studies after database searching, and 55 were included in quantitative and narrative synthesis. All analyses were done in tertiary care settings in densely populated central parts of Nepal. Ischemic stroke was more frequent (70.87%) than hemorrhagic (26.79%), and the mean age of stroke patients was 62,9 years. Mortality occurred in 16.9% (13-21.7%), thrombolysis was performed in 2.39% of patients, and no studies described thrombectomy or stroke unit care. CONCLUSION: The provision of stroke care in Nepal needs to catch up to international standards, and our systematic review demonstrated the need to improve access to quality stroke care. Dedicated studies on establishing stroke care units, prevention, rehabilitation, and studies on lower levels of care or remote regions are required.

Recent trends in cyclic vomiting syndrome-associated hospitalisations with liberalisation of cannabis use in the state of Colorado.

BACKGROUND: Currently, 33 states in the United States along with the District of Columbia have legalised cannabis in some forms. There is a paucity of data on the impact of legalisation of cannabis use on hospitalisations due to cyclic vomiting syndrome (CVS). AIM: To study the trends in CVS-related hospitalisations and cannabis use in CVS in relation to legalisation of recreational cannabis use in Colorado. METHODS: All hospital admissions in Colorado between 2010 and 2014 with the diagnosis of CVS were identified using the Colorado State Inpatient Database. Five-year trends in CVS-related hospitalisations along with the cannabis use were analysed. Multivariate logistic regression analysis was performed to determine predictors of cannabis use in CVS. RESULTS: There was a significant increase in CVS-related hospitalisations by 46% from 806 in 2010 to 1180 in 2014 when CVS was included as all-listed diagnoses (P < 0.001). The overall prevalence of cannabis use in CVS (13% with CVS as primary diagnosis and 17% with CVS as all-listed diagnoses) was much higher than non-CVS-related hospitalisations (1.7%) (P < 0.001 for both comparisons). Cannabis use increased dramatically in both CVS and non-CVS-related hospitalisations following legalisation of cannabis for recreational use in 2012. CONCLUSION: Our study shows a significant increase in CVS-related hospitalisations concomitant with an increase in cannabis use with its liberalisation in Colorado. Future studies on the relationship between cannabis use and hyperemesis are warranted, especially with its ongoing legalisation in the United States.

Cyclic vomiting syndrome: epidemiology, diagnosis, and treatment.

Cyclic-vomiting syndrome (CVS) is a chronic functional gastrointestinal disorder characterized by recurrent episodes of nausea and vomiting. Although once thought to be a pediatric disorder, there has been a considerable increase in recognition of CVS in adults. The exact pathogenesis is unknown and several theories have been proposed. Migraine and CVS share a similar pathophysiology as suggested by several studies. Since there are no specific biomarkers available for this disorder, physicians should rely on Rome criteria for the diagnosis. Due to the lack of randomized control trials, the treatment of CVS is primarily empirical.

Risk, Outcomes, and Predictors of Clostridium difficile Infection in Lymphoma: A Nationwide Study.

OBJECTIVE: The risk of Clostridium difficile infection (CDI) has not been well studied in patients with lymphoma. We thus sought to determine the risk of CDI in hospitalizations with lymphoma along with its trend, outcomes, and predictors using a large database. METHODS: Hospital discharge data from the Nationwide Inpatient Sample (NIS) from 2007 to 2011 were used for the study. Using the International Classification of Diseases, Ninth Revision, Clinical Modification codes, all adult patients aged 18 years or older having a primary diagnosis of lymphoma were queried for the presence of CDI as any of the secondary diagnoses. The risk of CDI in lymphoma and its yearly trend were assessed. We performed multivariate logistic regression to determine the independent risk factors of CDI in lymphoma. Furthermore, we studied mortality and other adverse outcomes of CDI in patients with lymphoma. RESULTS: There were 236,312 discharges (weighted) with the primary diagnosis of lymphoma. CDI was present in 2.13% of patients with lymphoma versus 0.8% in the nonlymphoma group (P < 0.001). On multivariate analysis, the significant predictors of CDI in lymphoma were presence of infection (odds ratio [OR] 3.1, 95% confidence interval [CI] 2.7-3.6), stem cell transplant (OR 2.7, 95% CI 2.3-3.4), graft-versus-host disease (OR 1.9, 95% CI 1.4-2.8), race (Asian vs white, OR 1.6, 95% CI 1.1-2.4), chemotherapy (OR 1.6, 95% CI 1.4-1.8), gastrointestinal surgery (OR 1.4, 95% CI 1.2-1.7), and Charlson Comorbidity Index (CCI) (CCI of 2 vs 0-1: OR 1.2, 95% CI 1.1-1.4; CCI of 3 vs 0-1: OR 1.3, 95% CI 1.03-1.6). CDI in lymphoma was associated with worse hospital outcomes such as increased mortality (17% vs 8%), increased length of stay (23.6 vs 9.9 days), mean total hospital charges ($197,015 vs $79,392), rate of intubation (13% vs 4% vs 13%), and rate of total parenteral nutrition (11% vs 3%). CONCLUSIONS: Hospitalization with lymphoma was associated with an increased risk of CDI. The significant predictors for CDI in lymphoma were infection, stem cell transplant, graft-versus-host disease, race, chemotherapy, gastrointestinal surgery, and Charlson Comorbidity Index. CDI in lymphoma was associated with increased mortality and other adverse outcomes warranting a need of more vigilance for CDI in patients with lymphoma.

A Case of Optic Neuritis Secondary to Lyme Disease.

INTRODUCTION: Optic neuritis is a condition associated with various systemic diseases, such as multiple sclerosis, and is also considered a rare complication of Lyme disease. CASE: A 46-year-old white woman presented with sudden onset of bilateral vision loss. After extensive workup, she was diagnosed with Lyme optic neuritis based on the clinical presentation and positive serology. She was treated with doxycycline for 2 weeks. DISCUSSION: Lyme disease is caused by infection with the spirochete Borrelia burgdorferi. The most commonly affected areas include the skin, joints, heart, and nervous system. Lyme optic neuritis is a challenging diagnosis and therefore often underreported. Doxycycline or ceftriaxone for 2 weeks are recommended for treatment. CONCLUSION: We report this case to increase awareness among clinicians to include Lyme disease in the differential diagnosis of optic neuritis for unexplained cases of vision loss, particularly in Lyme endemic areas.

Treatment of bile acid amidation defects with glycocholic acid.

UNLABELLED: Bile acid amidation defects were predicted to present with fat/fat soluble vitamin malabsorption with minimal cholestasis. We identified and treated five patients (one male, four females) from four families with defective bile acid amidation due to a genetically confirmed deficiency in bile acid CoA:amino acid N-acyl transferase (BAAT) with the conjugated bile acid, glycocholic acid (GCA). Fast atom bombardment-mass spectrometry analysis of urine and bile at baseline revealed predominantly unconjugated cholic acid and absence of the usual glycine and taurine conjugated primary bile acids. Treatment with 15 mg/kg GCA resulted in total duodenal bile acid concentrations of 23.3 ± 19.1 mmol/L (mean ± SD) and 63.5 ± 4.0% of the bile acids were secreted in bile in the conjugated form, of which GCA represented 59.6 ± 9.3% of the total biliary bile acids. Unconjugated cholic acid continued to be present in high concentrations in bile because of partial intestinal deconjugation of orally administered GCA. Serum total bile acid concentrations did not significantly differ between pretreatment and posttreatment samples and serum contained predominantly unconjugated cholic acid. These findings confirmed efficient intestinal absorption, hepatic extraction, and biliary secretion of the administered GCA. Oral tolerance tests for vitamin D2 (1,000 IU vitamin D2/kg) and tocopherol (100 IU/kg tocopherol acetate) demonstrated improvement in fat-soluble vitamin absorption after GCA treatment. Growth improved in 3/3 growth-delayed prepubertal patients. CONCLUSION: Oral glycocholic acid therapy is safe and effective in improving growth and fat-soluble vitamin absorption in children and adolescents with inborn errors of bile acid metabolism due to amidation defects.

Tandem mass spectrometric determination of atypical 3ß-hydroxy-Δ5-bile acids in patients with 3ß-hydroxy-Δ5-C27-steroid oxidoreductase deficiency: application to diagnosis and monitoring of bile acid therapeutic response.

BACKGROUND: 3ß-Hydroxy-Δ(5)-C27-steroid oxidoreductase (HSD3B7) deficiency, a progressive cholestatic liver disease, is the most common genetic defect in bile acid synthesis. Early diagnosis is important because patients respond to oral primary bile acid therapy, which targets the negative feedback regulation for bile acid synthesis to reduce the production of hepatotoxic 3ß-hydroxy-Δ(5)-bile acids. These atypical bile acids are highly labile and difficult to accurately measure, yet a method for accurate determination of 3ß-hydroxy-Δ(5)-bile acid sulfates is critical for dose titration and monitoring response to therapy. METHODS: We describe a electrospray ionization LC-MS/MS method for the direct measurement of atypical 3ß-hydroxy-Δ(5)-bile acid sulfates in urine from patients with HSD3B7 deficiency that overcomes the deficiencies of previously used GC-MS methods. RESULTS: Separation of sulfated 3ß-hydroxy-Δ(5)-bile acids was achieved by reversed-phase HPLC in a 12-min analytical run. The mean (SE) urinary concentration of the total 3ß-sulfated-Δ(5)-cholenoic acids in patients with HSD3B7 deficiency was 4650 (1711) µmol/L, approximately 1000-fold higher than in noncholestatic and cholestatic patients with intact primary bile acid synthesis. GC-MS was not reliable for measuring 3ß-hydroxy-Δ(5)-bile acid sulfates; however, direct analysis of urine by fast atom bombardment mass spectrometry yielded meaningful semiquantitative assessment of urinary excretion. CONCLUSIONS: The tandem mass spectrometry method described here for the measurement of 3ß-hydroxy-Δ(5)-bile acid sulfates in urine can be applied to the diagnosis and accurate monitoring of responses to primary bile acid therapy in HSD3B7 patients.

Genetic defects in bile acid conjugation cause fat-soluble vitamin deficiency.

BACKGROUND & AIMS: The final step in bile acid synthesis involves conjugation with glycine and taurine, which promotes a high intraluminal micellar concentration to facilitate lipid absorption. We investigated the clinical, biochemical, molecular, and morphologic features of a genetic defect in bile acid conjugation in 10 pediatric patients with fat-soluble vitamin deficiency, some with growth failure or transient neonatal cholestatic hepatitis. METHODS: We identified the genetic defect that causes this disorder using mass spectrometry analysis of urine, bile, and serum samples and sequence analysis of the genes encoding bile acid-CoA:amino acid N-acyltransferase (BAAT) and bile acid-CoA ligase (SLC27A5). RESULTS: Levels of urinary bile acids were increased (432 ± 248 µmol/L) and predominantly excreted in unconjugated forms (79.4% ± 3.9%) and as sulfates and glucuronides. Glycine or taurine conjugates were absent in the urine, bile, and serum. Unconjugated bile acids accounted for 95.7% ± 5.8% of the bile acids in duodenal bile, with cholic acid accounting for 82.4% ± 5.5% of the total. Duodenal bile acid concentrations were 12.1 ± 5.9 mmol/L, which is too low for efficient lipid absorption. The biochemical profile was consistent with defective bile acid amidation. Molecular analysis of BAAT confirmed 4 different homozygous mutations in 8 patients tested. CONCLUSIONS: Based on a study of 10 pediatric patients, genetic defects that disrupt bile acid amidation cause fat-soluble vitamin deficiency and growth failure, indicating the importance of bile acid conjugation in lipid absorption. Some patients developed liver disease with features of a cholangiopathy. These findings indicate that patients with idiopathic neonatal cholestasis or later onset of unexplained fat-soluble vitamin deficiency should be screened for defects in bile acid conjugation.

Follmann Balanitis: An Unusual Case of Syphilis.

A 33-year-old man presented with suprapubic abdominal pain and small vesicular lesions on the foreskin of the penis. Based on the presentation, he was empirically treated for genital herpes, although the herpes simplex virus swab was negative. He returned to the emergency department 4 months after his initial presentation with worsening symptoms that were consistent with balanoposthitis and cystitis. He was tachycardic and febrile on presentation. He denied any sexual contact for the last 3 months, with previous negative screening tests for sexually transmitted infections. Syphilis was eventually diagnosed during this admission. The incidence rates of syphilis have increased in recent years, and the infection is often undiagnosed given atypical manifestations. Here we present an atypical manifestation of syphilis that was initially misdiagnosed as herpes simplex virus.

Vitamin B12 deficiency presenting as neck pain and cervical radiculopathy.

Vitamin B12 is required for the formation of haematopoietic cells and the synthesis of myelin. Deficiency typically presents with fatigue and megaloblastic anaemia. Prolonged deficiency can cause neurological symptoms such as paresthesia, which can progress to subacute combined degeneration of the spinal cord. We describe an unusual presentation of B12 deficiency in a young man who was initially diagnosed and treated for cervical radiculopathy. This case highlights the challenges of diagnosing B12 deficiency in patients with neurologic but without haematologic, abnormalities. While the current incidence of B12 deficiency in developed countries is low, cases are likely to rise with the increased adoption of veganism. Clinicians should be aware of the variable presentations of B12 deficiency because delayed diagnosis and treatment increases morbidity and can cause irreversible neurological deficits.

Strategies to promote scholarship among academic hospitalists.

Academic hospitalists play an integral role in the day-to-day care of hospitalized patients, education and research. They are well-positioned to engage in scholarly and research activities and inform clinical practice. Hospital medicine also offers a compelling career path for those seeking to maintain a broad clinical focus while also pursuing opportunities in quality improvement (QI), clinical research, and medical education (MedEd) projects. Participation in these endeavors not only foster scholarly growth but also enhances career satisfaction for hospitalists. Therefore, there is a need to explore and implement feasible strategies to equip hospitalists with the knowledge and resources necessary to generate scholarship and promote academic growth within the field.

Necrotizing pancreatitis in an 8-year-old girl: a case report from Nepal.

Introduction and importance: Necrotizing pancreatitis is an uncommon diagnosis in pediatric patients. Early diagnosis is difficult as the presentation varies significantly. However, it should be in the differential diagnosis of abdominal pain in the pediatric age group. Case presentation: An 8-year-old girl arrived with a 1-day history of vomiting, constipation, and abrupt, increasing epigastric discomfort. She didn't have any noteworthy family or medical background. Upon examination, she seemed to be afebrile but also had discomfort in her stomach and symptoms of dehydration. An enlarged pancreas with necrotizing pancreatitis was seen in the first imaging. She received intravenous fluids, antibiotics, and analgesics as a treatment for her acute severe pancreatitis diagnosis. Since the patient continued to have fever, meropenem was prescribed in place of ceftriaxone at first. After 10 days of uncomplicated hospitalization, she was released from the hospital. Discussion: Once rare, pediatric pancreatitis now affects 3-13 out of every 100 000 people yearly. Although it is uncommon (<1% in children), necrotizing pancreatitis can happen. Its causes are similar to those of acute pancreatitis, involving genetic abnormalities and certain drugs. Abdominal discomfort, fever, vomiting, and nausea are among the symptoms. Imaging methods like contrast-enhanced CT are used in diagnosis. Surgery has given way to less intrusive techniques like catheter drainage as a form of treatment. Surgery is seldom required in pediatric instances, which are often handled conservatively. Conclusion: Childhood necrotizing pancreatitis is uncommon but dangerous; prompt diagnosis and prompt treatment are essential.

Severe Thrombocytopenia in Decompensated Liver Disease: An Example of Accelerated Intravascular Coagulation and Fibrinolysis.

INTRODUCTION: Advanced liver disease can present with severe thrombocytopenia that can be difficult to delineate and manage. Here we describe a unique entity of accelerated intravascular coagulation and fibrinolysis (AICF) in a patient with decompensated liver disease. CASE PRESENTATION: A 56-year-old male with a history of alcoholic cirrhosis was admitted for weakness, nausea, metabolic derangement, and acute kidney injury determined to be secondary to decompensated liver disease. During admission, his platelet count declined to <10 000/µL requiring 8 total platelet transfusions. Laboratory and clinical evaluation supported a diagnosis of AICF, and the patient gradually improved with supportive management. DISCUSSION: AICF can present similarly to disseminated intravascular coagulation, and careful evaluation of specific laboratory values is required for accurate diagnosis. Appropriate management minimizes the associated increased risk of bleeding and prevents delay in procedural intervention. CONCLUSIONS: This case highlights the importance of early clinical and laboratory correlation, multidisciplinary care, and supportive treatment in the management of AICF.

Granulomatosis With Polyangiitis Presenting As Orbital Apex Syndrome.

Granulomatosis with polyangiitis (GPA) is a rare small-vessel vasculitis that typically presents with a triad of sinonasal, pulmonary, and renal symptoms. Here, we present the case of a 43-year-old female with a history of substance use disorder who presented with vision changes and worsening left eye pain over five days. Previous evaluations raised concerns about GPA versus cocaine-induced vasculitis, but diagnostic confirmation was hindered by a lack of medical follow-up. Prompt multidisciplinary intervention led to significant improvement following steroid therapy and IV antibiotics, and the patient was ultimately diagnosed with a high GPA. This case highlights the complexities involved in diagnosing and managing GPA presenting as orbital apex syndrome, particularly in patients with comorbidities and non-adherence to medical follow-up.

Interaction of Semaglutide and Ziprasidone in a Patient With Schizophrenia: A Case Report.

Semaglutide (Ozempic), a GLP-1 receptor agonist effective in weight management, and ziprasidone (Geodon), an antipsychotic with a lower risk of metabolic side effects, are well-established in treating type 2 diabetes and schizophrenia, respectively. However, their interactions and effects on psychiatric symptoms are less understood. In this study, we report a case of a 43-year-old male with schizophrenia and diabetes with exacerbated paranoid delusions upon semaglutide administration for weight loss; symptoms peaked at higher doses and subsided after dose reduction. Concurrently, serum ziprasidone levels were significantly elevated at the dose reduction, suggesting a pharmacokinetic interaction likely due to semaglutide-induced slowed gastric emptying affecting ziprasidone's absorption and metabolism. This study illustrates the need for careful monitoring of psychiatric symptoms and drug levels when these medications are used together. Additionally, further research into their interactions to optimize treatment for patients with coexisting metabolic and psychiatric conditions is warranted.

Corpus callosal agenesis with gray matter heterotopia and bilateral eye coloboma in an infant: A case report.

Corpus callosal agenesis (CCA) is a rare congenital disorder characterized by the partial or complete absence of the corpus callosum, a structure crucial for interhemispheric communication. CCA can occur in isolation or be associated with other anomalies such as heterotopia, holoprosencephaly, cerebellar hypoplasia, coloboma, and hydrocephalus. The prevalence of CCA ranges from 0.020% to 0.025%, though some reports suggest higher rates. This case report describes a 1-year-old male with developmental delays and no significant antenatal or family history. MRI revealed a complete absence of the corpus callosum, asymmetrically dilated lateral ventricles, subependymal gray matter nodules suggestive of gray matter heterotopia, and bilateral posterior globe defects with vitreous herniation, indicating severe ocular anomalies. The child received supportive care including physical therapy and special education services, with regular follow-ups for developmental and ophthalmologic evaluation. This case report details the rare occurrence of CCA, accompanied by gray matter heterotopia and bilateral posterior eye coloboma in a pediatric patient. The combination of these congenital anomalies presents unique diagnostic and management challenges requiring multidisciplinary care. We discuss the clinical presentation, radiological findings, and implications for supportive care and improving the prognosis.

Retrocaval ureter presenting with hydronephrosis: A case report of rare entity in Nepal.

Hydronephrosis, characterized by the dilation of the renal pelvis and calyces, often results from obstructive uropathy, commonly due to ureterolithiasis. However, rare congenital anomalies, such as a retrocaval ureter (RCU)-where the ureter passes behind the inferior vena cava- can also cause hydronephrosis. This case report describes an 11-year-old male presenting with right-sided flank pain and hematuria. Initial ultrasonography and noncontrast CT revealed right hydronephrosis without ureteral stones. Subsequently, contrast-enhanced CT urography found an abnormality in the course of the right ureter behind the inferior vena cava. He was diagnosed with right retrocaval ureter with hydronephrosis, and managed by surgical resection of the retrocaval segment and uretero-ureteral anastomosis. The postoperative course was uneventful. RCU usually presents in the third or fourth decade of life, however, it should be in the differential diagnosis of hydronephrosis in the pediatric population. The diagnosis of RCU is often delayed and missed till advanced imaging like CT urography is sought for unexplained hydronephrosis. If left untreated, it may lead to chronic renal failure. Therefore, emphasis should be placed on timely diagnosis and management of retrocaval ureter.

Rhino-orbital-cerebral mucormycosis with Klebsiella and MRSA co-infection in a diabetic patient: a case report.

Introduction and importance: Rhino-orbital-cerebral mucormycosis is an opportunistic infection caused by fungus species Rhizopus and Mucor. Early recognition and aggressive management is crucial for favorable outcomes. A delay in diagnosis and treatment is fatal. Case presentation: A 32-year-old female presented with high-grade fever, right-sided facial deviation associated with facial swelling, and inability to move her left eye for 10 days. Biopsy from the left nasal cavity showed fibrinoid material, edema, and sheets of neutrophilic infiltrate while KOH preparation of nasal scrapping showed aseptate hyphae with obtuse-angled branching. Amphotericin B, oral posaconazole, and antibiotics were started with exploration and debridement of the affected tissue. The patient recovered well and was discharged. Discussion: Immunocompromised people are primarily affected by mucormycosis, a serious fungal illness. Inhaling fungal spores, especially those of the Rhizopus and Mucor species, is the usual cause. Rhinocerebral mucormycosis (ROCM), the most common type, increased during COVID-19 pandemic, frequently as a result of hyperglycemia brought on by steroids. Angioinvasion and tissue necrosis are pathogenesis-related processes that are made worse by diabetes and the overuse of glucocorticoids. Histopathology, culture, and imaging are used in the diagnosis. Surgery and antifungal drugs like Amphotericin B are used in treatment. Early intervention and interdisciplinary care, including hyperbaric oxygen therapy, are critical for survival. Results deteriorate with postponed therapy, underscoring the urgency of prompt action. Conclusion: Mucormycosis should be kept in mind while formulating differential diagnosis of infective pathology in immunocompromised patients. Early diagnosis and treatment are important in improving patient prognosis in rhino-orbital-cerebral mucormycosis.
