Encephalitis is challenging to manage given the diversity of clinical and epidemiologic features. Various predictors of outcome have been studied so far including thrombocytopenia, cerebral edema, hypoglycaemia, development of status epilepticus and need for endotracheal intubation. Thrombocytopenia represents one of the potentially modifiable risk factors for poor prognosis in encephalitis. A better understanding of the epidemiology of this devastating disease and identification of predictors of outcome and management of reversible factors will pave the way for better management of the disease. Material: A total of 98 Hospitalised patients of Acute Encephalitis were enrolled in the study. Diagnoses were confirmed by CSF and Neuroimaging studies. Platelet count <150,000/cumm was considered as thrombocytopenia. Mild, moderate and severe thrombocytopenia was categorized at platelet count 100,000-150,000, 50,000-100,000 and <50,000/ cumm, respectively. Outcome at discharge was assessed using the Modified Ranking Score, categorized into 3 groups - good (0-2), fair (3-4), and poor (5-6). Chi-square, ANOVA and Independent samples 't'-tests were used to compare the data. Observation: Mean age of patients was 34.06±18.76 (range 14-85) years. Majority of patients were males (54.1). Mean GCS at admission was 9.41±1.90. Acute viral encephalitis(unclassified) (n=33; 33.7%), Scrub typhus (n=24; 24.5%) and Japanese encephalitis virus (n=12; 12.2%) were the most common underlying etiologies. A total of 74 (75.5%) patients had thrombocytopenia. Mild, moderate and severe thrombocytopenia was seen in 34 (34.7%), 30 (30.6%) and 10 (10.2%) cases. Thrombocytopenia was significantly higher in Dengue and Scrub as compared to other etiologies. Thrombocytopenia and its severity showed a significant association with lower GCS and higher mRS scores indicating a poor outcome. Conclusion: Thrombocytopenia is associated with a poor clinical status and adverse outcomes in patients with encephalitis of all causes.

Ischemic Stroke is an acute and rapidly progressing neurological disease. Stroke is the second largest cause of global death (5.5 million) after ischemic heart disease. Numerous biomarkers have been identified and studied related to acute ischemic stroke but currently, none of the biomarkers are available for prognostication in such cases. In this study, we measured the levels of four widely available, rapidly measured biomarkers and evaluated their association with the functional outcome at discharge. Material: This was a prospective observational study conducted on 81 patients of acute ischemic stroke after obtaining informed consent. A detailed history was taken and clinical examination was done. Serum levels of homocysteine, uric acid, C-reactive protein (CRP), and Pro-brain natriuretic peptide (Pro-BNP) were measured at admission and their association with functional outcome using mRS (modified Rankin Scale) were analyzed. Observation: During the study period, 81 cases of acute ischemic stroke were evaluated; among them, 13 had a cardioembolic stroke. Ischemic stroke was more common in the older age group. The mean age was 49 ± 16.2 years. 61.7 % of patients were males. Diabetes Mellitus (45.7%), Hypertension (45.7%), CAD (8.6%), Dyslipidemia (27.2%), Smoking (37%), and alcohol intake (29.6 %) were some major risk factors. The average duration of hospital stay was 13.3 ± 7.5 days. 22 cases expired during the hospital stay. Mean serum levels of homocysteine, CRP, and Pro-BNP were higher than normal values (22.7 ± 16.3 umol/l; 59.5 ± 42.7 mg/dl; 1949 ± 3265.7 pg/ml). The mean serum uric acid level was 6.1 ± 3.3 mg/dl. A significant association between MRS score and serum homocysteine was found [p=0.007]. There was also a significant association between Pro-BNP levels and MRS score in patients with cardioembolic stroke (p=<0.001). Conclusion: Higher serum levels of homocysteine, CRP, and Pro-BNP are associated with a higher risk of acute ischemic stroke. Homocysteine level at admission can predict the poor outcome at discharge in patients of acute ischemic stroke. Pro-BNP levels can be used as a predictor of poor outcomes in cardioembolic stroke.

Dual antiplatelet treatment (DAPT) is the cornerstone of the management and prophylaxis of acute coronary syndrome (ACS). However, the associated risk of bleeding with the usage of DAPT and risk of thrombosis with stoppage of the drug makes it a challenging task to take appropriate decisions regarding the choice and duration of DAPT. The present study is aimed to tackle these challenges and to analyze whether prolonged dual antiplatelet therapy carries more risk of bleeding or a higher risk of thrombosis is present with discontinuation of the same. Material: In this study, a total of 235 cases of confirmed myocardial infarction, unstable angina, or those who underwent percutaneous intervention were included. After 1 year, the number of patients on DAPT, the type of antiplatelets they were using were observed, their ischemic risk was calculated using DAPT score, and bleeding risk was calculated using PRECISE-DAPT score. Bleeding events were assessed using BARC classification. Observation: Out of 235 patients, the majority of the patients were males (78.7%). Only 7.2% of the patients had bleeding since the start of the drugs. The majority (5% out of 7.2%) of bleeding episodes were clinically insignificant. 163 (69%) patients were on Dual antiplatelet therapy after 1 year. Out of which 115 were appropriately taking DAPT as per their DAPT score. Patients with high bleeding risk (PRECISE DAPT score ≥25) were 89, out of which 38 (53.2%) patients were taking SAPT, appropriate for their bleeding risk. While 112 (68.7%) were taking prolonged DAPT, appropriate for PRECISE-DAPT risk. Conclusion: The majority of patients remained on DAPT following discharge for more than 1 year after ACS. This suggests that treating physicians prioritizes ischemic risk reduction over bleeding risk in patients with ACS, according to the patient's risk profile.

As diabetes is on the rise worldwide, early screening and detection of its complications is crucial. The first clinical sign of renal dysfunction in diabetes is microalbuminuria. Ferritin may have a possible role in the development and prediction of microalbuminuria and other complications of diabetes by 3 possible mechanisms- 1) it is a marker of elevated body iron stores. 2) acts as acute-phase reactant and elevation reflects inflammation 3) Delayed clearance of glycosylated ferritin in patients with diabetes causes raised ferritin levels. In this premise, we studied the association between serum ferritin levels and microalbuminuria, glycemic control and dyslipidemia in type 2 diabetic patients. Material: A cross-sectional study was carried out at a tertiary hospital in northern India involving 152 patients of type 2 diabetes mellitus. Anthropometric measurements (weight, height), sample collection for basic laboratory parameters including complete blood count, kidney function tests, liver function tests, HbA1c, lipid profile, serum iron and ferritin levels, urinary albumin- creatinine ratio was done. A fundus examination was performed. Results were analyzed using descriptive statistics and making comparisons among various groups. Categorical data were summarized as proportions or percentages while discrete as mean. Chi-square test was used for testing associations. Observation: Mean serum ferritin levels were significantly higher in patients having microalbuminuria as against patients having normal urinary albumin- creatinine ratio (539 vs 292, p-value- 0.04). Patients having poor glycemic control (HbA1c > 7) had higher ferritin levels (p-value- 0.024). There was a near-significant association (p-value-0.06) between serum ferritin and triglyceride levels. More cases with raised serum ferritin had higher triglyceride levels. Patients having microalbuminuria had a higher prevalence of diabetic retinopathy (p-value- 0.003) and higher triglyceride levels (p-value- 0.041). Conclusion: Ferritin can act as a marker of diabetic nephropathy, poor glycemic control and dyslipidemia in type 2 diabetic patients. Our study, therefore, indicates that programs to prevent complications of diabetes would be more effective by placing greater emphasis on patients having higher ferritin levels.

Background: Chronic Obstructive Pulmonary Disease (COPD) is now considered as multisystem disorder with high cardiovascular mortality. The study was carried out with an objective to observe the pattern and variation of blood pressure (BP) using ambulatory blood pressure monitoring (ABPM) in COPD patients. Methods: Thirty six cases of COPD diagnosed by spirometry underwent ABPM for blood pressure evaluation. Thirty controls without COPD underwent spirometry and ABPM. Analysis were carried out both during wakefulness and sleep. Results: Out of 36 COPD cases 25 were found to be hypertensive on ABPM, while 2 out of 30 controls were found to be hypertensive on ABPM. A significant difference was found between blood pressure levels during the wakefulness, sleep, and 24-hour BP amongst COPD cases and controls. Higher blood pressure levels were observed in COPD patients then in control, except for diastolic levels during wakefulness. The normal nocturnal dip was attenuated in COPD patients whereas physiological dip was present in controls. Conclusion: COPD patients had higher blood pressure levels than the control group and had abnormal dipping pattern of blood pressure which may lead to high cardiovascular mortality in patients of COPD.

Context:Obstructive sleep apnea (OSA)-related hypoxemia stimulates release of acute-phase proteins and reactive oxygen species that exacerbate insulin resistance and lipolysis and cause an augmented prothrombotic and proinflammatory state which can leads to premature death.Aims:This study aims to study the prevalence of OSA in diabetic patients.Setting and Design:It was a cross-sectional study, done over a period of 1 year in a tertiary care hospital.Materials and Methods:A total of 149 type 2 diabetic patients were enrolled after taking written consent. All patients were subjected to STOP BANG questionnaire and patients falling in intermediate-high risk (score 3–8), were taken for overnight polysomnography to confirm the diagnosis of OSA (apnea hypopnea index ≥ 5).Statistical Analysis Used:Statistical Package for Social Sciences (SPSS) Version 21.0 statistical analysis software.Results:Fifty-five percent of our diabetic population were having OSA. The age of patients enrolled in the study ranged between 30 and 86 years and prevalence increases with an increase in age groups. Majority (61.7%) of our cases were males. Incremental trend in weight, body mass index (BMI), neck circumference, and waist circumference of OSA cases were found with increasing in severity of OSA. Mean levels of raised blood sugar and HbA1c were higher in severe OSA cases.Conclusions:OSA has a high prevalence in patients with type 2 diabetes mellitus. Patients with type 2 diabetes should be screened for OSA, even in the absence of symptoms, especially in individuals with higher waist circumference and BMI.

Introduction:Obstructive sleep apnea (OSA) and hypothyroidism are closely linked as hypothyroidism has been shown to lead to the development of OSA through multiple mechanisms. With the changing lifestyle patterns worldwide and increased prevalence of obesity, the burden of OSA has substantially increased. The association of OSA with hypothyroidism is essential to establish. If identified early, treatment of OSA and associated hypothyroidism can be done timely to minimize the potential harmful complications of OSA on all aspects of the patient's health.Aims:This study was done to find out the prevalence of OSA in hypothyroidism patients.Setting and Designs:It was a cross-sectional study, done over a period of 1 year in a tertiary care hospital.Materials and Methods:A total of 100 hypothyroidism patients were enrolled after taking written consent. All patients were subjected to STOP-Bang questionnaire and patient falling in intermediate-high risk (score3-8), were taken for overnight polysomnography to confirm the diagnosis of OSA (AHI ≥5).Statistical Analysis Used:The Statistical Package for the Social Sciences version 21.0 statistical analysis software.Results:Out of 100 patients, who underwent polysomnography, 74 (74%) cases had OSA (AHI ≥5). Out of total 74 OSA cases, 29 (39.2%) cases had mild OSA (AHI 5–14), 15 (20.3%) cases had moderate OSA (AHI 15–30), and 30 (40.5%) cases had severe OSA. The age of the study population ranged between 24 and 78 years and the mean age was 58.28 ± 11.22 years. The mean age of the patients in the OSA group (59.27 ± 11.17 years) was higher than the non-OSA group (55.46 ± 11.09 years). Majority (64%) of our cases were male, and the proportion of males was found to be higher than females in both the groups (OSA/non-OSA). The body mass index (BMI) of the OSA group was found to be statistically higher as compared to that of the non-OSA group (P = 0.040). The BMI was found to be higher in severe OSA, but it was not statistically significant (P = 0.128). The mean value of FT4 was lower and thyroid-stimulating hormone (TSH) was higher in the OSA group as compared with the non-OSA group. However, no significant association was found between FT4 and TSH values in both the groups. Out of 100 cases, 41 patients were treatment naïve with mean TSH value of 13.1 ± 7 and 59 were on treatment with mean TSH of 8.3 ± 4. Treatment-naïve patients had a statistically higher number (85.3%) of OSA cases in comparison to patients on treatment (66.1) (P = 0.030).Conclusions:Prevalence of OSA is quite high in hypothyroidism. Patients with hypothyroidism should be screened for OSA for early diagnosis, especially in individuals with higher BMI. Treatment of hypothyroidism reduces the prevalence of OSA.

Cocaine addiction is a common problem in the adolescent and the young adults, pharmacologic interventions to reverse the effects of which do not exist. Neurological complications of cocaine abuse, such as seizures, headache, ischemic or hemorrhagic stroke, or subarachnoid hemorrhage, can be disastrous as a result of uncontrolled vasoconstriction and vasculitic damage. The lone occurrence of subdural hematoma in the absence of any other intracranial hemorrhagic complication is rarely seen in patients of cocaine abuse. We wish to share our experience of one such patient who presented to us with an unusual combination of the widespread cerebral infarction and subdural hematoma.

Homocysteine (HCY) interferes with collagen cross-linking in bones and stimulates osteoclast activity. The activated osteoclasts secrete cathepsin K (CathK), a cysteine protease, in eminent quantity during bone resorption. Hyperhomocysteinemia may effect bone mineral density (BMD) through CathK. We, therefore, examined the relation between HCY and BMD along with CathK, 25-hydroxyvit-D (25[OH]D), intact parathyroid hormone (iPTH), and Vitamin B12. We recruited a total of 93 postmenopausal women between the age group of 45-60 years, attending the Endocrinology outpatient department at King George's Medical University, Lucknow. BMD was done by DXA scan using Hologic QDR1000 system. Based on the WHO criteria, patients were segregated into three groups as follows; normal bone mass, osteopenia, and osteoporosis. All women underwent routine biochemical laboratory parameters, HCY, Vitamin B12, and CathK levels. Among 93 postmenopausal women, 56% (52) had osteoporosis. Nineteen percent (...

Background: Tuberculous meningitis (TBM) is a major, global public health problem and its diagnosis remains problematic even after years of experience. Early diagnosis and treatment are of paramount importance as a delay in diagnosis can lead to irreversible central nervous system damage and mortality. Aims: To evaluate the role of cerebrospinal fluid (CSF) IS6110-based tuberculosis (TB) polymerase chain reaction analysis (PCR) as an efficient diagnostic tool for the diagnosis of TBM. Materials and Methods: This is a cross-sectional study carried out with patients clinically suspected to have TBM. A total of 102 cases were enrolled, out of which 15 patients were excluded from the study because of alternative diagnoses. An in-house IS6110-PCR method using a specific pair of primers designed to amplify the insertion sequence, IS6110 in the Mycobacterium tuberculosis genome was used to analyze CSF. Results: Our study showed PCR positivity in 51.7% cases. PCR gave a sensitivity of 100% and specificity of 68.9% against the cases of TBM confirmed by culture. Conclusion: IS6110 TB-PCR is a novel diagnostic tool that can diagnose a greater number of individuals with clinically suspected TBM with its rapidity, accuracy, and reliability, and its positivity even after 4 weeks of starting treatment makes it the diagnostic tool of choice.

Tobacco use is one of the main preventable causes of mortality and morbidity worldwide. The global disease burden due to tobacco use is huge with projected mortality of eight million lives per year by 2030. Metabolic syndrome (MS) is defined as a constellation of cardiovascular and endocrine risk factors such as insulin resistance, obesity, raised blood pressure, and abnormal lipid profile. The relationship between tobacco use and MS has been well established. Also, the causal association between tobacco use and development of individual components of MS is well established. The Uttar Pradesh Association of Physicians of India (UP API) has drafted this position statement on managing tobacco use among persons with or at risk of developing Metabolic Syndrome (MS). This position statement presents evidence-based recommendations as described below. Scope and purpose The objective of this position statement is to offer clinical recommendations for screening, diagnosis and management of t...

The cutaneous side effects of hydroxyurea are lesser known complication of long term hydroxyurea therapy in myeloproliferative disorders. We report a non-diabetic patient, who developed hydroxyurea dermopathy (leg ulcers) during long-term treatment with hydroxyurea for chronic myeloid leukemia (CML). The time course of the development of ulcers and its healing suggests that these resulted from the direct toxicity of hydroxyurea. We aim to increase clinical awareness of this problem.

Rabies is an almost always fatal disease that physicians and patients dread due to its dismal prognosis and limited treatment options. Transmission of this disease occurs through the bite of dogs and wild animals (like jackal in our case). Other rare forms of transmission may be through inhalation in bat-infested caves and human-to-human transmission by infected corneal transplants, solid organ and tissue transplantation, and sometimes in laboratory settings. Its diagnosis is usually clinical in the absence of availability of special laboratory investigations at the point-of-care facility. Few people have described the role of imaging in diagnosis. We hereby report a patient with rabies encephalitis, having a history of jackal bite and classical MRI findings that we can use for early diagnosis in the absence of typical clinical features and specialised diagnostic testing.
