Low tension breast hydatid cyst--a case report.

INTRODUCTION: Features of low tension in breast hydatid cyst and symptoms secondary to cyst dying and disintegration are unique and not yet reported in the literature. MATERIAL AND METHOD: An young woman of 30 years complained about pain and vague swelling in the right breast during follow-up with albendazole therapy following second laparotomy for post-surgical residual cavity of hydatid cyst in the left lobe of the liver. Breast ultrasound was diagnostic. RESULTS: Segmental breast excision revealed a large dead hydatid cyst. Postoperative course was uneventful. CONCLUSIONS: Breast hydatid cyst may become symptomatic and hypotensive after start of albendazole therapy.

Visceral manifestations of von Hippel-Lindau disease: value of ultrasound and CT imaging.

Visceral manifestations of von Hippel-Lindau disease (VHLD) are generally asymptomatic and their early detection is of considerable help in the management. This communication documents the usefulness of imaging studies in detecting visceral manifestations in two cases of VHLD.

Saccular coronary aneurysms: angiographic and clinical profile and follow-up of 22 cases.

Saccular coronary aneurysms are defined as aneurysms with the transverse dimension at least 1.5 times the longitudinal dimension. Out of 3,200 coronary angiograms reviewed, there were 22 patients (20 males) with saccular coronary aneurysms (totalling 25 aneurysms). The morphology of the aneurysms, the extent and severity of associated coronary lesions, the clinical profile and follow-up data of these patients were analysed. Aneurysms were located in left main coronary artery 3 (12%), left anterior descending coronary artery 13 (52%), right coronary artery 5 (20%) and left circumflex 4 (16%). There were 5 large aneurysms (> 15 mm in diameter) (1 in left main coronary artery, 2 each in right coronary artery and left anterior descending coronary artery) averaging 32 mm in size. Fifteen aneurysms had significant coronary artery stenosis located proximal to it, supporting the theory of post-stenotic dilatation as the aetiology of aneurysm formation. Two patients had associated muscle bridges distal to the aneurysm; 20 had atherosclerotic coronary artery disease and one had coronary artery ectasia. Five patients were lost to follow-up, which ranged from 1 year to 19 years (mean 5.3 +/- 4.1 years). No patient had history suggestive of rupture of the aneurysm on follow-up. Two patients had myocardial infarction in the territory of the vessel with the aneurysm. Rest of the patients were in NYHA class I/II. One large right coronary artery aneurysm was subjected to aneurysmectomy due to symptoms of tricuspid valve obstruction. One left main coronary artery aneurysm measuring 12 mm, on follow-up of 19 years increased in size to 45 mm, in addition the patient developed a right coronary artery aneurysm. Coronary risk factor profiles in the 20 patients with atherosclerotic coronary artery disease and aneurysms were similar to age- and sex-matched control population with atherosclerotic coronary artery disease without aneurysms.

Central pulmonary artery anatomy in right ventricular outflow tract obstructions.

We reviewed the cine-angiograms of 190 patients with right ventricular outflow tract (RVOT) obstructions for size and anatomy of pulmonary arteries, patent ductus arteriosus (PDA) and major aorto pulmonary collateral arteries (MAPCAs). Patients were grouped into three, Tetralogy of Fallot (TOF) with pulmonary atresia (group 1, N=86), TOF with pulmonary stenosis (group 2, N=97) and 7 cases of pulmonary atresia with intact interventricular septum (group 3). Out of 86 patients in group 1, 49 had PDA alone, 30 had MAPCAs alone, six had both and one had none. In group 2, 31 patients had persistent PDA and one patient had MAPCAS and PDA. A discrete stenosis (DS) of pulmonary artery was seen significantly more in patients with RVOT obstructions associated with PDA compared to patients without PDA (67/84 vs. 5/96). Out of the 84 cases with ducti, 53 had stenosis of the pulmonary artery at the site of ductus insertion. Thus presence of PDA was an important factor in the development of DS. The likely cause of pulmonary artery stenosis in TOF with PDA may be the opposing flows through RVOT and PDA producing a watershed effect at the ductus-pulmonary artery junction. Diffuse hypoplasia of pulmonary arteries (DH) was seen more significantly in RVOT obstructions associated with MAPCAs, compared to other patient groups (19/36 vs. 14/87). These small pulmonary arteries had no discrete stenosis and this diffuse hypoplasia might be the result of inadequate blood flow during intrauterine life [Harikrishnan S, Tharakan J, Titus T, Bhat A, Sivasankaran S, Bimal F, Syam Sunder KR, James, KJ.

A CAT-derived one to three session intervention for repeated deliberate self-harm: a description of the model and initial experience of trainee psychiatrists in using it.

We describe a new Cognitive Analytic Therapy (CAT)-based intervention for those who repeatedly self-harm. It is specifically designed to be deliverable by staff with no training in psychotherapy. The intervention is simply manualized into sequential tasks that are mediated by new CAT-style standardized tools. A particular feature of this intervention is the deliberate use of feelings elicited in the therapist ('counter-transference') as (a) a guide to how professional poise is being threatened or lost and (b) an indicator of the appropriate focus for this very brief therapy. The psychiatrists' reflection on their elicited feelings is mediated by a new CAT tool, the 'Assessor's Response File' developed in this project. Audiotape analysis suggested that following a very brief learning period, trainee psychiatrists were able to adhere to the structure of the model and arrive at an appropriate reformulation in the first session but tended to be collusive in reciprocating the patients' dysfunctional coping styles.

Coronary artery ectasia: angiographic, clinical profile and follow-up.

Out of 3200 coronary angiograms we reviewed, there were 144 cases of coronary ectasia--an incidence of 4.5 percent. Among these, 122 were associated with atherosclerotic coronary artery disease, i.e. coronary stenosis more than 50 percent (group A) and 22 not associated with coronary artery disease (group B). The patients in groups A and B were compared with age- and sex-matched patients (group C) (n=100) who had coronary artery disease alone without ectasia. The incidence of ectasia was not increased in patients with thoracoabdominal aortic aneurysm i.e. 2/154 (1.8%) or in patients with peripheral occlusive vascular disease i.e. 5/161 (3.1%). Ectasia was typed according to a modified version of the criteria proposed by Markis et al. Type II was the commonest, followed by type I, III and IV. Right coronary artery was the most commonly involved vessel by ectasia followed by left circumflex, left anterior descending artery and left main coronary artery. Diffuse ectasia was seen more frequently in right coronary artery and localised ectasia in left anterior descending artery. Patients in groups A and B had similar epidemiological characteristics, though more patients with ectasia alone (group B) had better left ventricular function and negative stress tests. The patients in group A had a similar incidence of previous myocardial infarction, coronary risk factor profile, treadmill exercise test status and severity of coronary artery disease when compared to group C. On a mean follow-up of 3+/-1.2 years, all the three groups had similar event rates.

Clinical and angiographic profile and follow-up of myocardial bridges: a study of 21 cases.

Myocardial bridging describes an angiographic entity, which is any degree of systolic narrowing of a coronary artery observed in at least one angiographic projection. Among the cineangiograms of 3200 patients reviewed, there were 21 cases (19 males) of myocardial bridges--incidence of 0.6 percent. Of these, seven had hypertrophic cardiomyopathy, six had atherosclerotic coronary artery disease and remaining eight had no evidence of either. All 21 patients had myocardial bridges in proximal or mid left anterior descending coronary artery. In addition, one case of hypertrophic cardiomyopathy had whole posterior descending coronary artery under a myocardial bridge. Another case of hypertrophic cardiomyopathy had a short normal segment of 5 mm inside a long myocardial bridge of 35 mm (tandem myocardial bridges). The length of the bridges varied from 10 to 35 mm (mean 24.5 +/- 4.5 mm) and diameter stenosis during systole varied from 40-90 percent (mean 70 +/- 8%). Two patients had large saccular coronary aneurysms proximal to the muscle bridge. Four of the eight patients who had neither hypertrophic cardiomyopathy nor coronary artery disease presented with acute anterior wall myocardial infarction and three of them had regional wall motion abnormality of left descending territory. Of the six patients who had coronary artery disease, one had 60 percent left descending artery lesion and two had recanalized segments proximal to the bridge. Five of the above six patients had significant stenosis of other coronary vessels. Four patients were lost to follow-up (mean period 3.4 +/- 2 years). In the coronary artery disease group, one patient underwent coronary artery bypass graft surgery for 3-vessel disease including graft to left descending artery and one developed inferior wall myocardial infarction. The patients in the hypertrophic cardiomyopathy group and "no hypertrophic cardiomyopathy-no coronary artery disease" group were free of events at last follow-up. Long-term prognosis of isolated myocardial bridges appears to be excellent. Degree of systolic narrowing or length of myocardial bridge does not correlate with event rates on follow-up.

Coronary artery fistula in children and adults: a review of 25 cases with long-term observations.

We studied 25 patients with coronary artery fistula between 1976 and 1994. Age ranged from 1 to 58 years. Twelve patients were symptomatic; seven had dyspnoea, four had angina, one had palpitation and one had syncope. Coronary arteries in four. Coronary artery fistula drained into right ventricle in 11, right atrium in nine, pulmonary artery in four and left ventricle in two. The Qp/Qs ranged from 1.0 to 2.6 with a mean of 1.39 +/- 0.38. Five patients had associated cardiac anomalies. Two had atrial septal defects, one had patent ductus arteriosus, one had atresia of proximal right coronary artery and in one patient, the right coronary was arising from left coronary artery. Five patients underwent surgery without any operative mortality. Thirteen patients were followed-up medically for a mean period of 6.1 +/- 5.1 years. There were no complications related to coronary artery fistula during follow-up. In one patient coronary artery fistula closed spontaneously.
