In severe form of tetanus, even with maximum dose of muscle relaxants, spasms and apnoeic spells may persist and that may be life-threatening. The aim of this study was to assess the effect of neuroparalysing the patients and then providing ventilatory support in bringing about their recovery. Forty-nine adult patients of severe tetanus (Ablett's grade IIIA--6 patients and Ablett's grade IIIB--43 patients) were studied during the period from April, 1993 to February, 1996. Mean period of onset ie, period from trismus to first spasm, in these patients was 24 hours. Patients were neuroparalysed with a bolus dose of 2-4 mg of pancuronium followed by a continuous infusion of 1-2 mg/hour and simultaneously supported with mechanical ventilation until spasms subsided. Fourteen patients (28.6%) survived and rest died. Mean duration of ventilatory support on survived patients was 14.4 days. The commonest complication encountered during ventilatory support was respiratory tract infection observed in 36 patients (73.5%). Commonest cause of death was autonomic imbalance encountered in 15 patients (30.6%). Treatment of choice in severe tetanus should be neuroparalytic ventilatory support. With use of new generation ventilators and better intensive care facility, death in severe tetanus is likely to be very less.

Tilt table testing has long been used as a standard tool in the diagnostic evaluation of syncope. However, differences of opinion exist with regard to its utility in the evaluation of patients with only presyncopal attacks. We present the results of drug-free, 70-degree head-up tilt table tests (maximum duration of 45 minutes), conducted between May 2002 and May 2003 in the Department of Physiology at JIPMER. This series consisted of both male and female patients (age 6-79 yr) with presyncope (n = 43), unexplained syncope (n = 43) and asymptomatic healthy volunteers without a history of syncope (n = 14). 28 out of 43 patients with unexplained syncope had a history of recurrent syncope while the remaining 15 had only 1 episode. 2 out of 43 patients (4.6%) with a history of only presyncopal attacks had a positive test (induction of intense presyncope and/or syncope accompanied by hypotension and/or a relative bradycardia). 21 out of 43 patients (49%) with a history of syncope had a positive test. 7 had vasodepressor syncope due to hypotension, 6 had cardioinhibitory syncope characterized by asystole and 10 had a mixed form of the vasovagal syndrome characterized by hypotension as well as bradycardia. 18 out of 28 patients (64%) with recurrent unexplained syncope had a positive test. All fourteen healthy volunteers had a negative test. We conclude that tilt table testing is useful in the diagnostic evaluation of patients with unexplained syncope, especially those with recurrent syncope, but not in the evaluation of patients with presyncope alone.

To describe the clinical presentation and response to treatment of four patients who presented with abdominal pain and were diagnosed to have lead poisoning.After ruling out the more obvious causes of abdominal pain by barium studies, gastrointestinal endoscopies, and biochemical studies, blood lead levels were estimated by atomic absorption spectrophotometry. The patients were treated with oral d-penicillamine.The four patients had blood lead levels from 79 microg/dL to 365 microg/dL. All four of them showed marked improvement in their clinical condition and lowering of blood lead levels on follow up.Clinicians need to develop a high index of suspicion of lead poisoning as a possible cause of unexplained abdominal pain or altered sensorium, especially against a background of environmental lead contamination in India.

Streptococcus agalactiae (S. agalactiae) is a rare cause of infective endocarditis, which is associated with a high mortality rate. Endocarditis in adults is generally related to immunocompromised states. We hereby report the case of a 35 year old man who presented with fever and delirium in whom aortic valve endocarditis due to S. agalactiae was detected. Though most patients with S. agalactiae endocarditis need surgical intervention along with antibiotics, our patient improved with medical therapy alone.

Membranous obstruction of vena cava (MOVC) is a common cause of hepatic venous outflow obstruction. Surgical procedures utilized to relieve symptoms carry a high morbidity and mortality. A patient who presented with gradual onset ascites and dilated, tortuous veins over the anterior abdominal wall and the back was found to have MOVC by inferior vena cavogram. Balloon dilatation of the obstruction was done successfully through a transvenous approach. Following this, the patient improved remarkably. The procedure is safe, effective and easy to perform. This balloon angioplasty provides alternative method for treatment of membranous obstruction of vena cava.

Though scorpion envenomation is known to lead to acute myocarditis and a reversible decrease in left ventricular function, it has not been implicated as an etiological factor in idiopathic dilated cardiomyopathy. We studied the association of idiopathic dilated cardiomyopathy with a history of scorpion sting as well as with socio-economic status, history of smoking and alcoholism, rural habitation, and history of snake bites.Consecutive cases of idiopathic dilated cardiomyopathy were recruited for this study: The association with putative risk factors was studied using a case-control study design with two sets of controls. One set of controls were age and sex matched inpatients selected at random, the other set of controls were spouse, or if not available, a close relative, ordinarily resident with the patient.On analysis, none of the factors except scorpion envenomation had a significant association. A past history of scorpion envenomation had an adjusted odds ratio of 8.01 (3.55-18.06) when compared to one set of controls and an odds ratio of 8.33 (6.55-10.59) when compared to the second group of controls.Our study indicates that a history of scorpion envenomation acts as a risk factor for the subsequent development of idiopathic dilated cardiomyopathy. Despite an apparently complete recovery from a scorpion sting, many patients probably retain sub-clinical deficits that predispose to the development of cardiomyopathy later in life, when other factors get added on. The known association of cardiomyopathy with catecholamine excess in experimental situations in animal studies, and in other disease states in humans, supports this hypothesis.
