Selective suture cutting for control of astigmatism following cataract surgery.

Use of 10-0 monofilament nylon in ECCE cataract surgery leads to high with the rule astigmatism. Many intraoperative and post operative methods have been used to minimise post operative astigmatism. We did selective suture cutting in 38 consecutive patients. Mean keratometric astigmatism at three and six weeks post operative was 5.76 and 5.42 dioptres (D) respectively. 77.5% of eyes had astigmatism above 2 D. Selective suture cutting along the axis of the plus high cylinder was done after six weeks of surgery. Mean post suture cutting keratometric astigmatism was 3.3 D and 70% of the eyes had astigmatism below 2 D. After 3 months of surgery mean keratometric astigmatism was reduced to 1.84 D. Axis of the astigmatism also changed following suture cutting. 40% of the eyes showed improvement in their Snellen acuity following reduction in the cylindrical power.

Renovascular hypertension due to Takayasu's arteritis among Indian patients.

Over a 16-year period, 205 patients with hypertension were shown to have a renovascular aetiology. Of these, 125 (61 per cent) had Takayasu's arteritis, 58 (28.3 per cent) had fibromuscular dysplasia, 16 (7.8 per cent) had atherosclerosis, five (2.4 per cent) had polyarteritis nodosa and one (0.5 per cent) had renal artery aneurysm. Among patients with Takayasu's arteritis, males were affected as commonly as females. The mean age of these patients at the time of detection was 26.8 +/- 8.6 years (range 5-52 years). Type I arteritis was seen in nine (7.2 per cent), Type II in 40 (32 per cent) and Type III in 76 (60.8 per cent) patients. The abdominal aorta was involved in 117 (93.3 per cent) patients. Takayasu's arteritis was associated with ulcerative colitis in two patients and with renal amyloidosis and focal segmental glomerulosclerosis with a nephrotic syndrome in one patient each. Surgical intervention consisting of bypass procedures, autotransplantation or nephrectomy was performed in 17 (13.6 per cent) and angioplasty in nine (7.2 per cent) patients. Cure and improvement in blood pressure was observed in 82.4 per cent and 77.8 per cent respectively. Adequate control of blood pressure was achieved with drugs only in 22 (22.2 per cent) patients. A definite cause and effect relationship could not be established between any infective or immunological disorder and Takayasu's arteritis. Takayasu's arteritis is a far more common cause of renovascular hypertension in Indian population than fibromuscular dysplasia or atherosclerosis, which are more common in the western population.

Spontaneous extrusion of cysticercosis: report of three cases.

We report three cases of spontaneous extrusion of cysticercosis. In two cases, it got extruded from the orbit and in one case from the subconjunctival space. Extrusion of cysticercosis was associated with improvement in clinical signs and symptoms.

Mesenteric and portal vein thrombosis presenting as acute intestinal obstruction.

Acute bowel infarction is a major complication in patients with superior mesenteric vein and portal vein thrombosis. However, in some patients, sufficient collaterals can prevent acute bowel infraction. We present a case of mesenteric vein and portal vein thrombosis with intestinal obstruction due to acute bowel oedema and ischaemic adhesion without infarction or stenosis.

Mycoplasma pneumonia associated with rhabdomyolysis and the Guillain-Barre syndrome.

A 25-year-old housewife who presented with Mycoplasma pneumonia who developed acute respiratory distress syndrome (ARDS) and required assisted ventilation. During her hospital stay, she developed acute renal failure because of rhabdomyolysis and was put on haemodialysis. She also had difficulty in weaning from ventilator because of acute motor-sensory axonal neuropathy (AMSAN) variant of the Guillain-Barre syndrome. The patient was treated with antibiotics and corticosteroids. The patient recovered from both the complications gradually.

A correlative study of ophthalmoscopy and fluorescein angiography in systemic hypertension.

This study correlates the fundus signs with the severity and signs of hypertension and evaluates the role of fluorescein angiography in detecting changes in the retinal and choroidal capillary bed in hypertension and defines its advantages over direct ophthalmoscopy. 37 hypertensives belonging to all grades of hypertension were studied. A thorough physical examination, hypertension work up, direct ophthalmoscopy and fluorescein angiography was done in all cases. A significant association was found between the presence of marked arteriolar narrowing and the presence of severe hypertension, left ventricular hypertrophy (LVH) and cardiomegaly. Patients having definite arterio-venous crossing changes and exudative retinopathy had a higher incidence of LVH and cardiomegaly. Renal functions and neurological signs in hypertension showed no correlation with the fundus signs. Capillary bed and choriodal abnormalities could be better studied on fluorescein angiography. Hard exudates were not visualized on fluorescein angiography. There was total resolution of exudative phenomenon on treatment.

Etiologic spectrum of acute sporadic viral hepatitis in children in India.

The relative magnitude by hepatitis A virus (HAV), hepatitis B virus (HBV) and hepatitis Non-A, Non-B virus (HNANBV) was determined in 496 children from three different parts of India suffering from acute viral hepatitis by tests for specific IgM class anti-HAV and anti-HBV antibodies in the serum. HAV, HBV and NANB infections accounted for 55.8 per cent, 20.2 per cent and 23.2 per cent of cases respectively. Hepatitis A largely (59.5%) affected younger children of 1-5 yr. Nearly a third of children affected by NANB hepatitis were additionally positive for HBsAg. The proportions of HAV and HBV infected cases respectively decreased and increased with increasing age whereas the incidence of HNANBV infection remained almost constant throughout childhood. Acute NANB hepatitis, a major health problem in the adults of India is also common throughout childhood. This study suggests that this infection does not impart long lasting protective immunity.

Patterns of recovery of pulmonary functions in severe acute bronchial asthma.

The recovery of pulmonary function were studied in fifty patients of acute bronchial asthma receiving a standard therapeutic regime. Sixty-two per cent of patients had achieved 50% of their total improvement in peak expiratory flow rate (PEFR) within 24 hours (fast responders) as against slow responders. Duration of asthma, characteristics of present exacerbation, mean pulse rate and presence of pulsus paradoxus on admission did not differ in fast and slow responders. The rise in PEFR within 4 hours of starting treatment was highly significantly correlated with a higher PEFR at 24 hours and a faster recovery. The mean arterial PaCO2 was higher (P less than 0.02) in slow responding group and they were slightly older (P less than 0.01), had lower mean FVC (P less than 0.01), mean FEV1 (P less than 0.02) and PEFR (P less than 0.001). The mean PaO2 of less than 80 mm Hg at 48 hours was more common in those with delayed recovery of PEFR.
