SOFA and APACHE II scoring systems for predicting outcome of neurological patients admitted in a tertiary hospital intensive care unit.

Background: The field of neurology encompasses the study and treatment of disorders that affect the nervous system, and patients with neurological conditions often require specialized care, particularly in the ICU. Predictive scoring systems are measures of disease severity used to predict patient outcomes. The aim of this study was to compare the discriminative power of commonly used scoring systems, namely the sequential organ failure assessment (SOFA) and acute physiology and chronic health evaluation II (APACHE II) in the ICU of a tertiary care hospital. Methods: This retrospective study included patients with neurological disorders in the ICUs of Tribhuvan University Teaching Hospital from 1 January 2022 to 31 December 2022. Results: A total of 153 patients were included. The mean age of the patients was 54.76 ± 17.32 years with higher male predominance (60.78%). Ischaemic stroke was the most common neurological disorder. There were 58 patients (37.9%) who required mechanical ventilation and all-cause mortality was 20.9%. The mean SOFA score was significantly higher (P=0.002) in survivors, whereas the mean APACHE II did not show a significant difference (P=0.238). Receiver operating characteristic (ROC) analysis showed the area of curve (AUC) of SOFA score was 0.765 and of APACHE II was 0.722. Conclusions: SOFA score had comparatively higher discriminative power than APACHE II. Assessment of the performance of scoring systems in a specific ICU setting improves the sensitivity and applicability of the model to these settings.

Assessing the comparative efficacy of plasmapheresis and Intravenous immunoglobulin in myasthenia gravis treatment: A systematic review and meta-analysis.

BACKGROUND: Myasthenia gravis (MG) is an autoimmune neuromuscular disorder characterized by muscle weakness, posing significant challenges to patients' daily lives. Intravenous immunoglobulin (IVIG) and plasmapheresis are two prominent immunomodulatory therapies used in MG management, but the choice between them remains a clinical dilemma. This systematic review and meta-analysis aim to evaluate the comparative efficacy of IVIG versus plasmapheresis in MG management. METHODS: We adhered to PRISMA guidelines and prospectively registered the review protocol in PROSPERO. Systematic search across electronic databases identified 14 studies meeting inclusion criteria. Data from these studies were extracted, and assessed risk of bias. Primary outcomes included clinical efficacy, while secondary outcomes encompassed hospitalization, ventilation, antibody titers, and treatment-related complications. Statistical analysis was conducted using R software. RESULTS: The pooled results indicated that patients receiving plasmapheresis had higher odds of any improvement in MG symptoms compared to IVIG. However, change in severity scores did not significantly differ between the two treatments. Hospitalization durations were similar, but IVIG-treated patients tended to have shorter stays. Antibody titers, particularly anti-MUSK antibodies, favored plasmapheresis treatment. Complication rates were comparable between two groups. However, severe complications were more common in plasmapheresis. CONCLUSION: This comprehensive analysis suggests that plasmapheresis may offer superior short-term symptom improvement in MG compared to IVIG, while IVIG may lead to shorter hospital stays and lower complication rates. The choice between these treatments should be tailored to individual patient needs and disease characteristics. Further research is needed to explore long-term outcomes and mortality rates in MG management.

Occurrence of osmotic demyelination syndrome in diabetes mellitus: A case report and literature review of various etiologies for osmotic demyelination syndrome.

Osmotic demyelination syndrome is a rare condition reported mainly in the case of rapid correction of hyponatremia, but it can occur even in the case of complicated diabetes mellitus either during rapid correction of hyperglycemia or anytime during the complicated diabetes mellitus. We report a case of complicated diabetes mellitus developing osmotic demyelination syndrome. The patient had presented with altered sensorium and seizure, which was initially diagnosed as hyperglycemia, but during his treatment, the magnetic resonance imaging of brain revealed central pontine myelinolysis. Our search on the causes of osmotic demyelination syndrome other than rapid correction of hyponatremia has revealed several other causes like autoimmune liver disease, Sjogren's syndrome and non-Hodgkin's lymphoma in addition to diabetes mellitus.

Guillain-Barre Syndrome following lower segment caesarean section under spinal anesthesia: A case report.

Symptoms of Guillain-Barre Syndrome (GBS) may be mistaken for typical puerperal changes, delaying diagnosis. Surgery and anesthesia may be triggers for GBS with an overall increase in pro-inflammatory cytokines in the postpartum period. We report a unique case of GBS in the postpartum period who made a good recovery with supportive measures.

Thyrotoxic periodic paralysis in a patient with Graves' disease: A case report.

Introduction and importance: Thyrotoxic periodic paralysis (TPP) is a rare and often misdiagnosed, hypokalemic periodic paralysis with features of mainly recurrent acute limb weakness with good treatment outcome if diagnosed early. Case presentation: We here report a case of a 25-year-old male with a history of recurrent bilateral upper and lower limbs weakness resolved by potassium infusion later found to have Thyrotoxicosis (Graves' disease). MRI scans of the brain had no abnormal finding while thyroid scintigraphy showed diffuse toxic goiter. Clinical discussion: Graves' disease shares a majority of TPP while, other causes like toxic adenoma, thyroiditis, toxic multinodular goiter, amiodarone induced thyrotoxicosis, levothyroxine intoxication and thyrotropin (TSH) producing pituitary adenoma are also associated with TPP. The management of thyrotoxicosis by medical therapy, surgery or radioactive iodine therapy is the mainstay of treatment of TPP patients. For the treatment of acute attacks, potassium administration is necessary keeping in mind the problem of hyperkalemia because of excess doses of potassium as it shifts to extracellular space. Conclusion: TPP should be considered as a differential in the cases of limb weakness and the secondary causes especially Thyrotoxicosis and precipitating factors should be identified.

Dengue encephalitis featuring "double-doughnut" sign - A case report.

Introduction: Dengue is a common febrile illness caused by Dengue virus and spread by Aedes mosquitoes. The neurological complications like encephalopathy or encephalitis or immune-mediated neurological syndromes are uncommon though. Discrete neuroimaging findings in this setting are even rarer. We report a case of dengue encephalitis with uncommon MRI features in a young female. Case presentation: The patient presented with complains of fever, vomiting, weakness in all limbs and difficulty in speech. Neurological examination revealed bilateral horizontal gaze palsy with impaired oculo-cephalic reflex, bulbar dysarthria and quadriplegia with bilateral planters up-going. Laboratory reported anemia, thrombocytopenia and positive NS1 antigen while excluding other tropical and immunological diseases. Brain MRI revealed extensive thalamic involvement as unique "double-doughnut" sign along with lesions in brainstem. The patient received supportive treatment in intensive unit and was discharged following improvement in clinical condition and laboratory reports. Clinical discussion: Dengue can infect the central nervous system directly as encephalitis or can have neurological consequences following multi-organ dysfunction and shock as encephalopathy or post-infection immunological syndromes as Guillain-Barré Syndrome or cerebrovascular complications or dengue muscle dysfunction. The MRI appearance of "double-doughnut" sign points towards dengue encephalitis in appropriate setting. Conclusion: A high index of suspicion is required to make a diagnosis of dengue encephalitis. The "double-doughnut" sign in MRI sequences has the potential to become a diagnostic marker for dengue encephalitis.

Ibrutinib in Refractory or Relapsing Primary Central Nervous System Lymphoma: A Systematic Review.

Primary Central Nervous System Lymphoma (PCNSL) is a rare variant of Non-Hodgkin Lymphoma (NHL) representing 1-2% of all NHL cases. PCNSL is defined as a lymphoma that occurs in the brain, spinal cord, leptomeninges, or eyes. Efforts to treat PCNSL by traditional chemotherapy and radiotherapy have generally been unsuccessful as a significant proportion of patients have frequent relapses or are refractory to treatment. The prognosis of patients with Refractory or Relapsed (R/R) PCNSL is abysmal. The optimal treatment for R/R PCNSL is poorly defined as there are only a limited number of studies in this setting. Several studies have recently shown that ibrutinib, a Bruton tyrosine kinase (BTK) inhibitor, has promising results in the treatment of R/R PCNSL. However, these are preliminary studies with a limited sample size. In this systematic review, we explored and critically appraised the evidence about the efficacy of the novel agent ibrutinib in treating R/R PCNSL.

An opportunity to improve Acute Ischemic Stroke care in the South Asian region through telestroke services.

The South Asian region accounts for more than 40% of the stroke burden of the developing world and is the highest contributor to global stroke mortality. Despite proven treatment guidelines, the limited number of neurologists, the number of dedicated stroke centers and the fact that most of these facilities are urban-centric renders poor access to thrombolysis in this region, especially in the rural areas. Studies have shown that thrombolysis using telestroke services are comparable to face-to-face thrombolysis. Telestroke, conducted through low-cost media such as smartphones or laptops, may form a cost-effective solution to improve access to appropriate stroke care in a resource-limited setting such as that of the South Asian region.

Role of female community health volunteers in ischemic stroke prevention, identification, referral and rehabilitation in Nepal.

For the past three decades, female community health volunteers (FCHVs) have been at the forefront of Nepal's health map and have contributed significantly to its improving health indicators such as maternal mortality rate and infant mortality rate. Given the changing epidemiology of Nepal and the shift of burden from communicable to non-communicable diseases (NCDs), it is important to revitalize their role with the changing times. The prevalence of ischemic stroke in Nepal is on the rise. However, very few people make it to the hospital within the time frame for thrombolysis and the patient's knowledge about ischemic stroke seems to play a major part. FCHVs can play a significant role in improving ischemic stroke care by raising awareness about the condition, its risk factors, and informing the public about the need for timely treatment. They can help screen for common risk factors such as obesity, hypertension and diabetes as well as monitor for treatment in previously diagnosed individuals. Randomized controlled trials have shown to yield favorable results in NCDs with engagement of FCHVs. With proper training and support, they can play an important role in improving ischemic stroke care in low- and middle-income countries like Nepal.

Low-cost alternatives for the management of acute ischemic stroke in low and middle-income countries.

Acute ischemic stroke (AIS) patients arriving within a suitable time frame are treated with recanalization therapy i.e. intravenous thrombolysis (IVT) with alteplase and/or mechanical thrombectomy (MT). IVT with alteplase is indicated in AIS patients presenting within 4.5 hours of onset regardless of vascular territory involved. MT is indicated in AIS patients presenting within 24 hours of onset with large vessel occlusion in the anterior circulation. However, MT is ludicrously expensive and requires exorbitant setup, devices, and expertise which is not currently feasible in LMICs. Therefore, in LMICs the only feasible recanalization option left for AIS patients is IVT. The cost of IVT varies across the LMICs, however, most of them cost around 2000-5000 USD. Apart from IVT, patients with AIS often have other significant medical costs including those for neuroimaging, intensive care, and prolonged rehabilitative treatment. In LMICs, these costs can only be afforded by a handful of patients. The majority of the LMICs have health insurance in their infancy and family members of AIS patients opt-out IVT due to the economic burden. In general, the current treatment guidelines for AIS are not very useful in LMICs because of cost-related issues among several other factors. In this editorial, we discuss evidence for alternative treatment strategies that can help tackle the rising epidemic of AIS in poor countries by improvising on existing clinical guidelines and seeking alternative treatment regimens.

Anti-LGI1, anti-GABABR, and Anti-CASPR2 encephalitides in Asia: A systematic review.

AIM: We aim to review the literature to collate and describe features of encephalitides arising from autoantibodies against leucine-rich glioma-inactivated 1 (LGI1), gamma aminobutyric acid receptor (GABABR), and contactin-associated protein-like 2 (CASPR2) in Asian populations and compare them with findings of Western studies. METHODS: Peer-reviewed articles published till 24 May 2020 were searched, and original, full-text studies from Asia with serum/CSF antibody-based diagnosis and at least 2 patients were selected. Twenty-four studies with 263 patients (139 anti-LGI1, 114 anti-GAGABR, and 10 anti-CASPR2) were included. Data were pooled to produce descriptive information on demographics, clinical characteristics, diagnostics, treatments, and outcome. RESULTS: The mean age was 54.2 (anti-LGI1), 55.2 (anti-GABABR), and 47.7 years (anti-CASPR2), with an overall male predominance of 62.0%. Commonest clinical features across all types were seizures (87.5%), memory deficits (80.7%), psychiatric disturbances (75.9%), and altered consciousness (52.9%). Four anti-LGI1, 40 anti-GABABR, and 1 anti-CASPR2 patients had tumors. CSF, MRI, and EEG were abnormal in 33.3%, 54.1%, and 75% patients in anti-LGI1; 60.0%, 49.6%, and 85.7% in anti-GABABR; and 50%, 44.4%, and 100% in anti-CASPR2 patients, respectively. 95.6% patients received first-line therapy alone (steroids/IVIG/Plasma therapy), and 4.4% received second-line therapy (rituximab/cyclophosphamide). 91.7%, 63.6%, and 70% of patients had favorable outcomes (modified Rankin Score 0-2) with mortality rates at 2.5%, 23.2%, and 0% in the three types, respectively. CONCLUSION: Our findings suggest that these disorders present in Asian patients at a relatively young age often with features of seizures, memory deficits, and psychiatric disturbances and usually demonstrate a favorable clinical outcome.

Hepatitis B virus induced cytoplasmic antineutrophil cytoplasmic antibody-mediated vasculitis causing subarachnoid hemorrhage, acute transverse myelitis, and nephropathy: a case report.

BACKGROUND: Transverse myelitis, subarachnoid hemorrhage, and nephropathy are established but rare complications of hepatitis B virus infection that can potentially be triggered by an antibody-mediated vasculitis as a result of a viral infection. The following is a case report detailing a patient presenting with all three of the above presentations who is cytoplasmic antineutrophil cytoplasmic antibody-positive and a chronic carrier of hepatitis B. CASE PRESENTATION: A 33-year-old Nepalese man presented to our hospital with headache, swelling of his body, paraplegia, and back pain that developed over a period of 10 days. Laboratory studies showed proteinuria and elevated levels of serum urea and creatinine. Viral serology was suggestive of chronic inactive hepatitis B carrier state. A computed tomography scan of his head revealed features suggestive of subarachnoid hemorrhage. Magnetic resonance imaging of his dorsal spine showed diffuse T2 high signal intensity within his spinal cord extending from second to 12th thoracic vertebral level which was suggestive of transverse myelitis. The origin of these symptoms was attributed to immune complex-mediated vasculitis after serum analysis for cytoplasmic antineutrophil cytoplasmic antibody came out positive. He was managed with steroids administered orally and intravenously and entecavir administered orally. CONCLUSION: This case highlights the possibility of a hepatitis B virus-induced vasculitis as the cause of subarachnoid hemorrhage, transverse myelitis, and nephropathy.
