Prevalence of obstructive sleep apnoea among patients admitted with acute coronary syndrome in a hill state of northern India.

Background Obstructive sleep apnoea (OSA) is one of the emerging non-traditional cardiovascular risk factors. Studying OSA may contribute towards a better understanding of current concepts of atherogenesis and in guiding therapy. Methods We conducted this cross-sectional study among 66 patients with acute coronary syndrome (ACS) in a tertiary care hospital from 1 January 2019 to 30 June 2020. We included patients of ST elevation myocardial infarction (STEMI)/ non-STEMI (on achieving Killip class I/II) and unstable angina and performed in-hospital overnight polysomnography (PSG) within 8 weeks of index event. Apnoea-hypoapnoea index (AHI) value 5-<15 was defined as mild OSA, AHI 15-<30 as moderate OSA and AHI >30 as severe OSA. We analysed data using Epi Info version 7.2.4 for Windows. Results The 66 patients had a mean (SD) age of 57.7 (11.1) years and 54 (81.8%) were men. Forty-three (65.1%) patients had STEMI, 19 (28.7%) had non-STEMI and 4 (6%) had unstable angina. On PSG, the prevalence of OSA (AHI>5) was 78.8% (95% CI 67.0-87.9). Of these, AHI >15 was significantly associated with diabetes, hypertension and different measures of obesity (p<0.05). Conclusions This study, conducted in a hill state of northern India, showed a high prevalence of OSA in patients with ACS. Obesity, diabetes mellitus and hypertension were significantly associated with severity of OSA (AHI>15).

Adrenal Tumor with Inferior Vena Cava Tumor Thrombus: A Case Report and Review of Literature.

Purpose: To report a rare case of secondary adrenal tumor with tumor thrombus in inferior vena cava (IVC) managed by three-dimensional laparoscopy and review the relevant literature. Case Report: A 60-year-old male patient operated for left-sided renal cell carcinoma 7 years ago, presented with asymptomatic secondary right adrenal tumor with tumor thrombus extending into the IVC through the right adrenal vein. A three-dimensional laparoscopic adrenalectomy with en bloc tumor thrombus evacuation from the IVC was performed. Literature Review and Discussion: The available literature was scanned and reviewed. There was a paucity of literature on the secondary adrenal tumors with IVC thrombus and to the best of our knowledge so far there is no reported case of secondary right adrenal tumor with IVC tumor thrombus that has been managed by three-dimensional laparoscopy. Conclusion: Secondary adrenal tumors with IVC tumor thrombus are rare but challenging and can present after many years of primary surgery. The low-level vena cava tumor thrombus can be managed with three-dimensional laparoscopy.

Neurological manifestations of scrub typhus in adults.

In order to study the neurological manifestations in adult patients suffering from scrub typhus, 323 patients aged over 18 years, admitted with a positive diagnosis, were screened for neurological dysfunction; 37 patients with symptoms and/or signs suggestive of neurological dysfunction were included in the study. Of these, 31 (84%) patients had altered sensorium, four (11%) had cerebellitis, one (2%) patient had acute transverse myelitis and one (2%) had bilateral papilloedema without focal neurological deficit. Of the 31 patients with altered sensorium, 15 (40%) had meningoencephalitis, three (8%) had seizures, two (5%) had cerebral haemorrhages, one (2%) had a presentation likened to neuroleptic malignant syndrome (NMS) and one (2%) had a 6th nerve palsy with inflammation of the right cavernous sinus. Cerebrospinal fluid (CSF) analysis was abnormal in 23 patients (raised lymphocytes in 68%, raised protein in 80%). All patients improved with anti-rickettsial therapy.

Prevalence of metabolic syndrome among newly diagnosed hypertensive patients in the hills of Himachal Pradesh, India.

To study the prevalence of metabolic syndrome (MS) among newly diagnosed hypertensive patients in a tertiary care hospital in the northern hilly state of Himachal Pradesh, India, located in western Himalayas at a moderate altitude of 2200 m above mean sea level. One hundred and eighteen newly diagnosed hypertensive patients above the age of 20 years were studied in a hospital-based cross-sectional study. MS prevalence was estimated by International Diabetes Federation (IDF) criteria and modified National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) criteria. Student's t-test was used to compare the mean of the continuous variables. Chi-square test was used to compare discrete variables. The prevalence of MS in hypertensive patients was 68.6% (modified NCEP-ATP III) and 63.6% (IDF criteria). The most common phenotype of MS with the component of hypertension was the coexistence of waist circumference (90.1%), low high-density lipoprotein (HDL; 70.4%), and high triglycerides (67.9%) as per the modified NCEP-ATP III criteria, and low HDL (76.2%) and high triglycerides (66.4%) as per the IDF criteria. Fasting blood glucose (33.2% as per the modified NCEP-ATP III criteria and 32.6% as per the IDF criteria) was the least significant factor having an association with MS. The prevalence of MS among hypertensive patients was high and indicates the need for metabolic screening in all hypertensive patients at the first diagnosis.
