Impending myocardial ischaemia during thyroid storm diagnosed through Wellens' syndrome.

We present a case of thyroid storm precipitated by discontinuation of antithyroid drugs. The patient developed a concurrent acute coronary event during the resolution period of the thyroid storm. After 48 hours of prudent management of thyroid storm, the patient's sensorium and haemodynamics were stabilised but he had persistent mild chest discomfort and developed new-onset jaw pain. On admission, ECG showed sinus tachycardia. In consideration of persistent mild chest discomfort and new-onset jaw pain, serial ECGs were performed which revealed biphasic T waves in V2-V3 suggestive of Wellens' syndrome type A. This indicated a critical stenosis of the left anterior descending (LAD) coronary artery and impending myocardial ischaemia. The patient underwent urgent coronary catheterisation, which revealed 80% stenosis of proximal LAD and was subsequently revascularised resolving his symptoms. This case underscores the significance of serial ECG monitoring even after the acute phase of thyroid crisis, which helped in timely identification of Wellens' syndrome.

Prevalence and Risk Factors for Resistant Hypertension: Cross-Sectional Study From a Tertiary Care Referral Hospital in South India.

Background Around 10% patients with hypertension have resistant hypertension (RH). Older age, Black race, obesity, diabetes mellitus (DM) and chronic kidney disease (CKD) are the common risk factors for RH. The present study was done to find out the prevalence and factors associated with RH. Methods This cross-sectional study was done between December 2018 and February 2020. Adult patients registered with the hypertension clinic and on care for more than three months were included in the study. History was noted and blood pressure (BP) was measured using standard precautions. The patients were divided into two groups - resistant and non-resistant hypertension. Chi-square test was done to check the significance of the differences between the two groups. Binary logistic regression was done for the risk factors with a p-value < 0.2 in the Chi-square test. Results A total of 275 patients were included. The mean age was 56 ± 10 years and 61% were females. The mean duration of hypertension was 7 ± 5 years; 77% of patients were overweight or obese. A family history of hypertension was present in 30% and 18% had diabetes mellitus. History suggestive of secondary hypertension was present in 13%. BP was controlled (<130/80 mm of hg) in 145 (53%), uncontrolled in 130 (47%) and resistant hypertension was seen in 31 [(11%) 95% CI 8-16%] patients. Duration of hypertension, obesity, and elevated fasting blood sugar were significantly associated with RH.  Conclusions RH was found in 11% of hypertensive patients. Longer duration of hypertension, obesity, and higher fasting blood glucose were associated with RH.

Neurological recovery with serological response in a rabies survivor on long-term follow-up.

An 18-year-old girl presented with headache, vomiting, dysarthria, diplopia and ataxia following a stray dog bite 20 days prior to presentation. The dog was killed by her neighbours. She received three doses of anti-rabies vaccine and one dose of rabies immunoglobulin (RVIG) before presentation. Diagnosis of rabies was confirmed based on four-fold rise in serum and CSF rabies virus neutralizing antibodies (RVNA) by rapid fluorescent focus inhibition test (RFFIT) titres coupled with history of dog-bite and a normal MRI. With supportive care and empirical administration of IVIG her condition improved over months and at her final visit to hospital at five years, she was physically independent with mild persistent dysarthria. Ours is one of the longest followed cases of rabies survivor in whom we had used IVIG empirically and could demonstrate the decline in the RVNA level in CSF and verify the steady neurological recovery over five years.
