The 1996 outbreak of dengue hemorrhagic fever in Delhi, India.

A major outbreak of dengue hemorrhagic fever (DHF) affected more than 10,000 people in Delhi and neighboring areas in 1996. The outbreak started in September, peaked in October to November and lasted till early December. The clinical and laboratory data of 515 adult patients admitted to Lok Nayak Hospital, New Delhi were reviewed. Fever (100%), myalgias and malaise (96%), abdominal pain (10.2%) and vomiting (8.7%) were the prominent presenting features. Hemorrhagic manifestations were seen in all patients- a positive tourniquet test (21.2%), scattered petechial rash (23.07%), confluent rash (2.7%), epistaxis (38.4%), gum bleeds (28.06%) and hematemesis (22.86%) being the major bleeding manifestations. Hepatomegaly was observed in 96% of the patients. Laboratory investigations revealed thrombocytopenia, hemoconcentration and leukopenia. Serological confirmation with a microcapture ELISA technic was done in 143/515 patients. The mortality rate was 6.6% and, multiple bleeding manifestations, severe thrombocytopenia, hypoproteinemia and dengue shock syndrome (DSS) were associated with a higher mortality.

Senior-Loken syndrome with unusual manifestations.

The Senior-Loken syndrome, also called Hereditary Renal Retinal Dystrophy is a rare disorder that combines a juvenile nephronophthisis-like disease with tapetoretinal degeneration. We are reporting a family in which two, possibly three siblings are affected by this disorder. In addition to these two documented components of the disease, our patients also have unusual manifestations: short stature; skeletal abnormalities in the form of kyphoscoliosis, short metacarpals; and cutis laxa-unreported so far.

Angiotensin converting enzyme inhibitors and cough--a north Indian study.

Cough is an important side effect of Angiotensin Converting Enzyme Inhibitor (ACEI) therapy. The incidence of cough was investigated in a prospective 8 week study in 250 hypertensive patients receiving ACEI alone or in combination with other agents. Enalapril (5-20 mg/day), Lisinopril (5-20 mg/day), Captopril (25-75 mg/day) or Ramipril (5-15 mg/day) was prescribed to patients, who were followed up at weekly visits. Cough developed in 73 of the 250 patients i.e. an incidence of 29.2%. Females had a higher incidence of cough as compared to males--37.9% versus 15.5% (p < 0.001) and there was no significant difference in the cough incidence in the various age groups. A dry, non-productive cough developed in all patients within 4 weeks of ACEI initiation. Increased nocturnal intensity of cough was reported by 79.4% patients. Cough incidence was 34.4%, 24.3% and 18.1% in patients on Enalapril, Ramipril and Lisinopril, respectively. Cough was not dose related and was not related to smoking. There was no statistically significant difference among patients on ACEI alone or in combination with beta blockers, calcium channel blockers or diuretics. Of the 18 patients with ACEI induced cough who received Indomethacin, 50 mg bid, 8 reported complete cure and cough was reduced in intensity in the remaining ten.

Aortic aneurysm presenting as Budd Chiari syndrome.

Budd Chiari Syndrome is the eponymic designation of symptomatic post sinusoidal venous obstruction, whether or not this is associated with hepatic vein occlusion or vena caval obstruction. Dutta and associates (1) classified the syndrome into two distinct types. Type I involves obstruction to the hepatic veins while Type II pertains to an obstruction in the inferior vena cava above the entry of hepatic veins. We report a case of thoraco-abdominal aortic aneurysm presenting as Type II Budd Chiari Syndrome.

Comparative evaluation of the antihypertensive effect of timolol and propranolol in patients with essential hypertension.

Fifty patients with essential hypertension were studied for the antihypertensive effect of timolol and propranolol. In 16 out of 25 patients on timolol therapy (64%) blood pressure could be brought well under control (defined as diastolic blood pressure less than 90 mmHg) while with propranolol 13 out of 25 patients (52%) responded. Side-effects were negligible with timolol as compared to propranolol therapy. This study revealed that timolol is an effective and safe drug in essential hypertension, and is tolerated better than propranolol by the patients.
