Penicillin-induced immune haemolytic anaemia is very rare. A ten year-old-female with rheumatic mitral stenosis on benzathine penicillin prophylaxis presented with features of haemolytic anaemia and investigations supported the diagnosis of immune haemolytic anaemia. Patient responded to discontinuation of the drug and therapy with oral prednisolone. This is first such case reported from India.
AIMS: To study clinical features, pattern of involvement and treatment modalities of Takayasu's arteritis (TA) in children. MATERIAL AND METHODS: Retrospective analysis of hospital records of children admitted over a period of 4.5 years. RESULTS: 17 patients in the age group of 5 to 11 years (M: F = 1.1: 1) were diagnosed to have TA on the basis of Ishikawa's criteria. One child was diagnosed post-mortem. The commonest presenting features were hypertension (64. 7%), congestive cardiac failure (47%), weak or absent peripheral pulses, cardiomyopathy (41.1% each) and cardiac valvular affection (35.2%). Retinopathy, hypertensive encephalopathy and abdominal bruits were uncommon. None presented in the prepulseless phase. No patient had an active tuberculous lesion, although Mantoux or BCG test was positive in 6 (35.2%). The predominant pattern of angiographic affection was Type II (52.9%). Nephrotic syndrome and portal cavernoma seen in one patient each were incidental associations. Anti-hypertensive drugs, oral steroids and drugs to control congestive heart failure were the mainstays of medical management. Antitubercular therapy was started in six patients. Angioplasty was attempted in 15 cases and proved to be partially beneficial in six. Three patients who failed to respond to medical management had to undergo surgical procedures, either bypass, nephrectomy or both. In-hospital mortality was 11.7%. CONCLUSIONS: Patients of TA in this study presented acutely in the pulseless phase, with hypertension and its complications. Type II involvement was the commonest pattern. Anti-hypertensive agents and steroids along with angioplasty were partially successful in controlling symptoms in 35.2%. Surgical procedures were reserved for a minority with poor response to drugs and angioplasty.
Neurofibromatosis (NF), Noonan syndrome (NS), and LEOPARD syndrome are all autosomal dominant conditions, each being a distinct clinical entity by itself. Rarely, one encounters cases with features of NF and NS and is termed as the 'Neurofibromatosis-Noonan syndrome' (NF-NS). The authors report a clinical dilemma with major clinical features of the NF-NS syndrome and LEOPARD syndrome co-existing in the same patient. Also, features of Noonan syndrome and LEOPARD syndrome are compared with the case reported.
Enteric fever is a common infectious disease of the tropical world, about 80% of these cases occur in Asian countries. Enteric fever presenting with isolated cerebellar ataxia or nephritis is rare. We report three cases of enteric fever that presented with these complications. Isolated cerebellar ataxia usually occurs in the second week, whereas in our cases it presented within first four days of fever. The common complications of enteric fever related to the urinary tract are cystitis, pyelitis, and pyelonephritis. Glomerulonephritis is uncommon. Most patients with enteric glomerulonephritis present with acute renal failure, hypertensive encephalopathy, or nephritic syndrome. In comparison, our case had milder manifestations. All three patients were treated with parenteral ceftriaxone and showed a prompt recovery.
Autosomal translocations are rare in the patients with ovarian dysgenesis. An 18-year-old female who presented with primary amenorrhoea had hypergonadotropic hypogonadism and streak ovaries with hypoplastic uterus. Karyotype analysis revealed a balanced autosomal translocation involving chromosomes 1 and 11. The probable role of autosomal translocations in ovarian dysgenesis has been discussed.
