Traditional coagulation tests often fail to predict bleeding risks associated with neuraxial blockade. Thromboelastography (TEG) offers real-time insights into coagulation status, potentially improving safety outcomes. In this case series, six patients underwent neuraxial blockade guided by TEG analysis. An individualized anesthetic plan was formulated based on TEG findings to mitigate bleeding risks while ensuring pain management. Tailoring anesthetic techniques to real-time TEG data improved safety outcomes with minimized bleeding complications and satisfactory pain control. In conclusion, neuraxial blockade guided by TEG enhances safety in patients with uncertain coagulation profiles. Further studies are needed to validate benefits in broader clinical settings.

Here we report three cases of PHA with medullary nephrocalcinosis and how medullary nephrocalcinosis in one patient led to misdiagnosis as renal tubular acidosis (RTA). Although PHA and RTA can share overlapping symptoms, careful evaluation of clinical presentation, biochemical tests, and imaging studies are essential to differentiate between the two conditions and ensure appropriate management. Also, awareness of this uncommon manifestation of PHA is essential to avoid misdiagnosis as tubulopathy, as this may delay the treatment.

METHODS: Real-time PCR analysis was employed to precisely identify the viral strain in conjunctival swab samples. A total of 80 patients were tested, and specific clinical symptoms were assessed. RESULTS: The study revealed the first documented case in India and the second worldwide of adeno-enterovirus conjunctivitis. The prevalence among the tested patients was significant, with 15% testing positive. Those infected with adeno-enterovirus exhibited shorter illnesses (≤3 days). Notably, clinical symptoms such as subconjunctival hemorrhage, chemosis, swelling, photophobia, and epiphora were significantly linked to this viral variant. Multivariable logistic regression analysis highlighted swelling and photophobia as robust predictors for identifying adeno-enterovirus conjunctivitis cases. CONCLUSION: The findings underscore the urgent need to recognize adeno-enterovirus conjunctivitis as a potential threat, capable of causing significant ocular morbidity. Swelling and photophobia emerged as robust predictors for identifying cases, emphasizing the importance of vigilant monitoring and comprehension of this viral variant. Proactive measures are essential to address its clinical implications and mitigate its impact on affected populations. Ongoing research is crucial to unravel the complete spectrum of adeno-enterovirus conjunctivitis and guide effective management strategies.

METHODS: A retrospective cross-sectional online questionnaire-based study was undertaken between July 2021 and November 2021, in which first-year Indian medical students who were enrolled in the Bachelor of Medicine, Bachelor of Surgery (MBBS) program in the year 2019 and appeared for the MUHS summative university examination in February 2021 were invited to participate. Analysis was done using JASP (v0.16.0.0), and the odds ratio for failure was calculated at a significance level of P < 0.05. RESULTS: Responses were obtained from 360 individuals, of whom 74.5% had passed and 25.5% had failed (n = 360). The odds of failure in first-year MBBS summative university examination was higher in students with irregular Internet access, irregular device access, an unsupportive peer environment in college, a National Entrance cum Eligibility Test score below 500, an unsupportive family environment during the lockdown, severe stress, severe depression, testing positive for COVID-19 before the exam, death in the family during the exam, and failing in terms and prelims and students of male gender ( P < 0.01). CONCLUSION: The total failure rate of 27% in the MUHS examination was mainly attributed to interplay between the student's mental health, lack of devices or Internet, and the changed assessment part of the CBME curriculum. Surprisingly, lecture frequencies, teaching patterns, and study resources did not influence the failure rate. These results can be used to formulate interventions that will help to improve academic performance and mental health students and thus help them adapt to the new curriculum.

Most cases of intracranial neuroblastomas occur due to metastasis from some primary extracranial sites and are known as secondary neuroblastomas. However, the occurrence of primary central nervous system neuroblastomas (PCN-NB) is very rare, and only a few cases and case series have been reported in the literature. PCN-NB is mainly an intra-axial pathology, and extra-axial involvement is mainly due to metastasis from some extracranial primary site with involvement of the skull bone. Herein we report a case of a 23-year-old female having a large extra-axial space-occupying lesion in the right frontal region that was mimicking a meningioma, and surprisingly the histopathology was suggestive of a supratentorial neuroblastoma. A right frontal craniotomy was made, and Simpson's grade 1 excision of the tumor was done. The excised tissue was sent for histopathological examination. PCN-NB located extra-axially are extremely rare to occur. Due to inconsistent radiological imaging, it becomes very difficult to diagnose these tumors preoperatively, and these should be kept in mind as one of the differential diagnoses of extra-axial intracranial space-occupying lesions. Histopathological examination is crucial in diagnosing the intracranial neuroblastomas.

One rare risk factor is Behçet's disease (BD). Out of around 3000 cases at our center in the past 10 years, two cases of BD with CVT were seen. Herein, we report on their clinical symptoms, course, and management. Case 1 was a 18-year-old girl with a history of recurrent skin lesions presenting with encephalopathy syndrome due to CVT, requiring decompression. Despite our best efforts, she developed complications and expired due to sepsis. Case 2 was a 22-year-old male with raised intracranial pressure syndrome and a history of recurrent orogenital ulcers. His evaluation showed retinal vasculitis, papilledema, and bilateral lateral rectus palsy. Both had CVT on neuroimaging and had positivity for human leukocyte antigen-B51. Case 2 responded to the anticoagulation and immunomodulation. Risk factor identification is essential in managing CVT, and planned evaluation (clinical or investigations) plays an important role in identifying rare causes that need specific treatment.

Both are misleading tools for predictions. A ROC curve is drawn for the sensitivity of a quantitative test against its (1 - specificity) at different values of the test. Both sensitivity and specificity are retrospective in nature as these are indicators of correct classification of already known conditions. They are not indicators of future events and are not valid for predictions. Predictivity intimately depends on the prevalence which may be ignored by sensitivity and specificity. We explain this fallacy in detail and illustrate with several examples that the actual predictivity could differ greatly from the ROC curve-based predictivity reported by many authors. The predictive efficacy of a test or a model is best assessed by the percentage correctly predicted in a prospective framework. We propose predictivity-based ROC curves as tools for providing predictivities at varying prevalence in different populations. For optimal cut-off for prediction, in place of the Youden index, we propose a P-index where the sum of positive and negative predictivities is maximum after subtracting 1. To conclude, for correctly assessing adequacy of a prediction models, predictivity-based ROC curves should be used instead of the usual sensitivity-specificity-based ROC curves and the P-index should replace the Youden index.

We report a young couple who presented with signs and symptoms of painful sensorimotor peripheral neuropathy in a typical "stocking and glove" pattern. They had raised urinary arsenic levels with normal blood levels and thus, a diagnosis of chronic arsenic poisoning due to contaminated water intake was made after detecting elevated arsenic levels in their home water supply. Both patients underwent chelation therapy with dimercaprol for 14 days and reported subjective and objective improvement in symptoms with the reduction in urinary arsenic levels at the end of therapy.

We report an infrequent co-occurrence of both these diseases in an adolescent male. It may appear that in some individuals, the rheumatic fever may act as a trigger for the development of large vessel vasculitis. This possibility should be considered in patients on follow-up if they develop fresh features of cardiovascular compromise despite appropriate medical, interventional, or surgical therapy for rheumatic heart disease.

The association between SA and cardiac and neurological disease is known. This study investigates the relationship between SA and cardiovascular and cerebrovascular outcomes in the ESRD population. METHODS: In a retrospective cohort study, the United States Renal Data System was queried to identify ESRD patients aged 18-100 years in whom hemodialysis had been initiated between 2005 and 2013. Diagnoses of SA and clinical comorbidities were determined from International Classification of Disease-9 codes. Demographic variables were obtained from Centers for Medicare and Medicaid Services Form-2728. Logistic regression was used to examine the association of SA with myocardial infarction (MI) or with stroke, controlling for demographic and clinical variables. RESULTS: Of 858,131 subjects meeting the inclusion criteria, 587 had central SA, and 22,724 had obstructive SA. The SA cohort was younger, more likely to be male and Caucasian compared to the non-SA cohort. Patients with SA also had more tobacco and alcohol use, hypertension, heart failure, and diabetes. Central SA (aRR = 1.69, 95% CI = 1.28-2.23) and obstructive SA (aRR = 1.15, 95% CI = 1.09-1.21) were associated with an increased risk of stroke but not MI. CONCLUSION: In the ESRD population, a diagnosis of central SA or obstructive SA increased the risk of stroke, but not MI. Early identification and treatment of SA in the ESRD population may help reduce the risk of stroke in these patients.
