Echocardiographic diagnosis of supravalvular aortic stenosis.

The echocardiographic features of supravalvular aortic stenosis seen in a patient with valvular aortic and multiple pulmonary branch stenosis are described. Since patterns of valvular, discrete subvalvular, and supravalvular aortic stenosis can be recognized by echocardiography, it is now possible to screen close relatives of patients having supravalvular aortic stenosis and pulmonary branch stenosis by this non-invasive technic.

Long-stay patients with long-stay drugs. A case review; a cause for concern.

The psychotropic medication of 200 long-stay psychiatric patients was reviewed by the consutant in charge of the ward, the ward doctor, and the ward sister. Those patients in whom medication was altered or stopped were reassessed by the same team after 6 months. About half the patients on medication had been receiving unnecessary or excessive medication.

Evaluation Studies as Topic↗

[Herpes gestationis. Immunopathologic studies in mother and child].

Herpes gestationis is a nosologically undefined uncommon bullous disease in pregnancy. In a patient with herpes gestationis C3, C5 und C9 deposits could be demonstrated by immunohistological methods at the epidermal basement membrane (BM). Deposits of immunoglobulins, properdin and C3PA were absent. Autoantibodies against BM were found in the serum of the mother by using rabbit oesophagus but not with normal human skin as antigen. In the sera of mother and child a factor could be demonstrated which in vitro leads to complement fixation in human epidermal BM. Immunopathological findings may speak in favor of a nosological entity of herpes gestationis with respect to dermatitis herpetiformis and bullous pemphigoid.

Renal artery stenosis in patients with peripheral vascular disease in Kuwait.

OBJECTIVE: The aim of this study was to identify the incidence of atherosclerotic renal artery stenosis (RAS) in patients with peripheral vascular disease (PVD) and its relation to any known risk factors. SUBJECTS AND METHODS: This prospective study was conducted on 212 patients who were subjected to peripheral angiography for symptoms of PVD over a 3-year period from 1995 to 1998 at the Mubarak Al-Kabeer Hospital, Kuwait. Angiographic evidence of atherosclerotic disease and its severity was recorded in renal, abdominal aorta, iliac, femoral, popliteal and below-knee arteries. In addition, a detailed search of identifiable risk factors was done using history, clinical examination and laboratory studies. RESULTS: The incidence of significant atherosclerotic RAS (more than 50% diameter stenosis) in patients with PVD was 15/212 (7.07%) with no significant difference in ratio between males and females (p = 0.3) compared to that of PVD alone. Patients with common iliac and femoral artery lesions had a high incidence of RAS (93.3 and 86.7%, respectively) with more than 80% probability in RAS patients with involvement of these vessels. There was significant renal impairment (p < 0.005), as assessed by serum creatinine levels, in patients with RAS compared to those who did not have it. There was a high incidence of smoking in patients with RAS (p = 0.02), and smoking was the only risk factor identified in these subjects. CONCLUSIONS: Patients with iliac or femoral atherosclerotic disease have a high probability of associated RAS. Presence of renal impairment in patients with PVD is highly indicative of RAS. Smoking is the only identified risk factor for RAS in association with PVD in our population.

Ischemic renal disease in Kuwait.

Ischemic renal disease (IRD) is a frequent cause of end-stage renal disease. Its prevalence is mainly known from autopsy or retrospective arteriographic studies. This prospective study was conducted in 115 subjects selected from 732 patients with advanced chronic renal failure (CRF). Only patients with clinical features suggestive of IRD were selected for this study. In addition to detailed clinical and laboratory evaluation, captopril renal scintigraphy was performed in selected cases. All subjects underwent renal arteriography and all were followed up for 18.4 +/- 11.4 months. Renovascular disease was seen in 15 patients and significant bilateral renal artery disease leading to IRD was observed in 13 (11.3%). Hence the prevalence of IRD in the advanced CRF patients was 1.7%. The majority of patients with IRD (8 [61%]) were above 46 years of age and there were more men than women (10:3). Atherosclerotic renovascular disease was the most common (10 [77%]), even though arthritis (1 [7.6%]), and fibromuscular dysplasia (2 [15.3%]) were also observed. Serum creatinine at time of presentation was significantly higher in patients with IRD (784 +/- 292, p = 0.043) compared to those who did not have IRD (359 +/- 126). Corrective procedures were performed in 5 patients. After treatment the improvement in serum creatinine in patients with IRD at 3 and 6 months (166 +/- 32 and 173 +/- 47, respectively) was significantly different (p < or = 0.05) compared to those who were not treated (610 +/- 194 and 645 +/- 220, respectively). Hyperlipidemia, coronary artery disease and peripheral vascular disease were more prevalent in patients who had IRD compared to those with renal failure. The incidence of diabetes mellitus were similar in both groups. This study denotes a lower prevalence of IRD in the advanced CRF population; they had more severe renal failure at presentation but specific corrective treatment delayed progression of renal disease significantly.
