Chylothorax--a conservative approach (a case report).

Lymphatic blockage due to a non-specific inflammation probably of a filarial origin caused dilatation and ectasia of lymph channels at thoracic inlet of a child. Transudation of lymph through these channels led to chylothorax. The present case report highlights the significance of conservative approach towards this complex problem.

Effect of sublingual isosorbide dinitrate in portal hypertension.

Nitrates decrease portal pressure by decreasing portal venous inflow and resistance. We studied over 20 minutes the effect of 10 mg isosorbide dinitrate sublingual on intrasplenic pulp pressure, mean arterial pressure and heart rate, in 13 patients with cirrhotic or non-cirrhotic portal hypertension. The pulp pressure fell progressively over 20 minutes, from mean 43.6 +/- 2.4 (SEM) to 35.6 +/- 1.8 cm H2O (p less than 0.001). This was accompanied initially by a significant fall in mean arterial pressure (85.8 +/- 1.9 to 80.4 +/- 2.7 mmHg at 4 minutes; p less than 0.01) and rise in heart rate (92.5 +/- 5.0 to 102.6 +/- 5.9 per minute at 6 minutes; p less than 0.02), following which these parameters remained stable. One patient developed giddiness due to hypotension at 15 minutes. We conclude that sublingual isosorbide dinitrate decreases pulp pressure in cirrhotic and non-cirrhotic portal hypertensives, but this is initially accompanied by significant hemodynamic changes.

The predictive value of myocardial perfusion scintigraphy after stress in patients without previous myocardial infarction.

Seventy-five patients who had chest pain but no history or ECG evidence of myocardial infarction (MI) underwent myocardial-stress perfusion scintigraphy (MSPS) with thallium-201, treadmill-stress testing (TST), and coronary cineangiography (CA). The sensitivities of MSPS and TST for coronary stenosis greater than or equal to 75% were 68% and 71%, respectively; their specificities were 97% and 79%, respectively (0.1 greater than p greater than 0.05). When the character of a patient's chest pain is considered, Bayesian analysis leads to the following conclusions: (a) MSPS can be useful in pre-CA screening of patients with chest pain but no MI if their pain is thought to be of uncertain or nonischemic origin: (b) the sensitivity of Tl-201 MSPS is not sufficient for pre-CA screening of patients without MI who have typical or atypical angina pectoris; (c) the sensitivity of MSPS would have to be approximately 95% in order for the test to be useful in pre-CA screening of patients who have atypical angina pectoris; (d) MSPS may be superior to TST in these applications; and (e) it is not clear that there is any advantage in combining MSPS and TST into a single screening test rather than using MSPS alone.

Referred pain to the ipsilateral forehead and orbit: An unusual phenomenon during bronchial artery embolization.

PURPOSE: We report an unusual pattern of referred pain to the ipsilateral forehead and orbit observed during bronchial artery embolization (BAE) for massive hemoptysis due to pulmonary tuberculosis (TB) and postulate possible neural mechanisms for its occurrence. METHODS: Seven men, from a series of 194 patients (171 men, 23 women) undergoing BAE (right bronchial artery 4, left 3) with gelatin sponge for control of massive hemoptysis due to pulmonary TB form the subject of this report. RESULTS: Embolization was successful in achieving control of hemoptysis in these patients and there were no complications following the embolization. Transient, moderately severe, ipsilateral supraorbital and/or retroorbital pain occurred only during the injection of the gelatin sponge contrast mixture into the bronchial artery. The pain did not occur during the injection of heparinized saline or ionic contrast medium. CONCLUSIONS: Referred pain during BAE is an unusual phenomenon. Acute vessel distension triggering visceral sensations is probably the causative mechanism. Sympathetic afferents from the bronchi coursing through the posterior pulmonary plexus eventually pass to the trigeminal ganglion via the carotid sympathetic chain. The ophthalmic and maxillary divisions of the trigeminal nerve then mediate pain sensation to the ipsilateral forehead and orbit. Similarly, parasympathetic afferents from the pulmonary plexus crossing the nucleus of the spinal tract of the trigeminal nerve may be responsible for interexchange of impulses to the neurons in this nucleus. Sensory fibers of the ophthalmic and maxillary nerves relaying in this nucleus are then involved in this pain being referred to the forehead and orbit.

Pancreatic carcinoid: an unusual tumour in an uncommon location.

Primary pancreatic carcinoid is an extremely rare pancreatic neoplasm. It differs from other primary pancreatic tumours in cytoarchitecture, immunocytochemistry and biologic behaviour. Recognition of this rare entity is of vital importance having considerable therapeutic and prognostic implications. We report a case of an exophytic, pancreatic body carcinoid tumour in a man who presented with abdominal pain. The diagnosis was established by histopathological examination of the core biopsy specimen. A surgical resection of the lesion was done successfully and the patient made a satisfactory recovery from the operation.

A giant vascular hamartoma of the breast in a child.

Vascular tumors of the breast are uncommon. Perilobular hemangiomas, the commonest histologic subtype of breast hemangiomas, constitute majority of microscopic, vascular mammary tumors. Macroscopic hemangiomas and vascular hamartomas of the breast are distinctly rare. We describe a giant, vascular hamartoma of the right breast in a five year old girl and discuss pertinent literature.

Study of Takayasu's arteritis in children: clinical profile and management.

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.
