Impotence, a common problem especially among older men, can now be treated with Viagra, This oral pill, unlike previous approved treatments mostly involving local injections, does not directly cause penile erection, but increases response to sexual stimulation. It acts by enhancing the relaxant effects of nitric acid on smooth muscle, and thus increases blood flow to certain areas of the penis, leading to erection. It has been evaluated in many randomized trials and in all was more successful in inducing erection than placebos. The most common side-effects include headache, flushing and indigestion, but there have also been reports of fatalities.

We describe a 75-year-old man who had an acute myocardial infraction in the past and who had maturity-onset diabetes and hypertension. In the week prior to admission he had a cardiac scan following a few weeks of exacerbation of anginal pain for which he had been taking nitrites. He took a Viagra pill without prescription or medical advice and 2 hours later, during intercourse with his wife, developed audible respiratory distress and lost consciousness. His wife started cardiac massage but not mouth-to-mouth breathing. The emergency team found ventricular fibrillation and gave 5 electrical shocks and amines and atropine. He remained unconscious, but his pulse returned and he was hospitalized. He then had several generalized convulsions treated with IV valium. 20 minutes after admission there was asystole and all attempts at resuscitation failed.

Cardiovascular status must be considered prior to prescribing Viagra, and the associated risk evaluated.

Brucellosis is rare in pregnancy. Recently, an increase in the incidence of this disease has been observed in our area. We present 7 cases of brucellosis in pregnancy and review the literature on the effects of brucellosis on the outcome of pregnancy. Brucellosis is rare in the Middle East and Africa and the most common source of infection is unpasteurized milk products. Brucella is a coccobacillus, gram-negative bacterium, whose hosts are mostly animals.

There is controversy about the relationship between brucellosis and the outcome of pregnancy. There is some evidence that there is a higher rate of complications such as abortion, premature rupture of membranes and preterm delivery in infected animals. Reasons for this difference in the impact of brucella in animals and man include the absence of the carbohydrate erythritol in the human placenta, which appears to be a preferential medium and growth factor for brucella in the placentas of animals.

There is uncertainty regarding effects of brucella in early pregnancy and no evidence of its transplacental passage in later pregnancy, causing adverse obstetrical outcome, although recently there has been a single report of Brucella abortus (biotype 2). 
We present 7 cases of brucellosis in pregnant women found between 1977-1988. Its incidence among the women who delivered here is 0.007% (7/92,768 deliveries). Our first case was complicated by preterm premature rupture of membranes and preterm delivery in the 20th week of gestation. In 2 other cases there was preterm delivery with 1 developing clinical chorioamnionitis. The 4 remaining women delivered at term, although 1 had preterm premature rupture of membranes and intra-uterine growth retardation, and 2 had postpartum endometritis.

270 consecutive electroencephalograms (EEGs) performed in a psychiatric hospital were reviewed. 194 (75%) were within normal limits but 66 (25%) showed diffuse generalized slowing. The contribution of the abnormal EEGs to diagnosis and treatment was evaluated by retrospective file review. In none of the cases with abnormal EEGs was there a relationship to diagnosis or treatment.

Sensory loss in the operative area after superficial parotidectomy is one of the complications which disturbs the patient. The greater auricular nerve, which stems from the cervical plexus, supplies sensation to the area. Sacrifice of the nerve during superficial parotidectomy causes sensory loss in the area. We investigated the degree of sensory loss in the operative area after superficial parotidectomy in 10 patients in whom the posterior branch of the greater auricular nerve was preserved and compared the results with those in whom it was not, a year after operation. There was more sensory loss when the greater auricular nerve was sacrificed. We therefore suggest preserving the posterior branch of the greater auricular nerve during superficial parotidectomy if at all possible.

Diaphragmatic hernias in adults that are not categorized as hiatal hernias are rare. Hernias of the diaphragm itself appear in the perinatal age group and are defined as congenital hernias, presenting with severe respiratory distress and requiring immediate repair. There are a few asymptomatic postpartum cases in young children or adults.

We present 3 cases of diaphragmatic hernia in men, aged 19, 20 and 74, respectively. 2 were admitted because of colonic incarceration with strangulation in the hernial sac. In the other case there was an incidental finding of incarcerated colon in a diaphragmatic hernia discovered in a patient who initially presented with unrelated thoraco-abdominal trauma. Contrary to the dominant clinical presentation as infant-respiratory distress, the predominant findings in adults are gastrointestinal complications.

We believe successful treatment is more likely when there is a high level of awareness of the possibility of this kind of hernia in the adult, which can be a recurrence after perinatal hernia repair. It is essential to recognize that this is a combined thoraco-abdominal problem since it is often necessary to perform simultaneous laparotomy, thoracotomy and stoma formation.

Diskitis in Brucellosis not Responsive to Anti-Brucella Treatment

A 14-year-old girl with fever and low back pain was diagnosed as having brucellosis and diskitis. Treatment with doxycycline and gentamicin had no effect nor was there any improvement when the treatment was changed to doxycycline and rifampicin. With cessation of this treatment and administration of cloxacillin fever was reduced and the back pain disappeared. After 12 days of IV cloxacillin, she was released from hospital with instructions to continue cloxacillin orally for another 4 weeks. We conclude that when a patient is suffering from brucellosis and diskitis and does not respond to the usual anti-brucellosis treatment, an anti-staphylococcal preparation should be added.

Gastric leiomyosarcoma (GLMS) is a malignant, smooth muscle neoplasm accounting for not more than 0.45%-3.5% of primary gastric malignancies and 17%-20% of all smooth muscle tumors of the stomach. A well-chavariant has been variously referred to as leiomyoblastoma and epithelioid leiomyosarcoma. Because of the rarity of GLMS, few authors have tried to correlate clinical presentation, pathological findings, and treatment. There is no uniform therapeutic approach for leiomyosarcoma of the stomach and reported survival rates vary widely. We present a 56-year-old man whom we treated for this condition.

Professional Assessment of Senior Immigrant Physicians

Israel has absorbed many immigrant physicians and has utilized their skills without compromising local professional standards. In accordance with this policy a special law for the assessment of the licensing of senior immigrant physicians, mainly from the former Soviet Union, who had practiced medicine for at least 14 years was implemented in 1994.

Considering their considerable medical experience on the one hand and their lack of experience in speaking Hebrew or undergoing testing techniques, they were exempted from the written national licensing examination. Instead they were obliged to undergo a 6-month clinical observation period in a local hospital or clinic.

At the end of this period a letter of confirmation was issued which was followed by an oral assessment of their clinical ability. In the assessment session, each candidate was presented with written presentations of 4 typical clinical cases which practitioners encounter on a daily basis, in family medicine, emergency medicine, surgery, and pediatrics or gerontology. Of 114 cases prepared, 4 were selected for each candidate by the committee of 13 trained, experienced Israeli physicians.

3 members of the committee assessed each candidate using specified criteria. The assessment, which lasted about an hour, focused on the candidates' professional knowledge involved in differential diagnosis and case management.

Of 497 candidates examined between 1994 and 1996, approximately 80% passed in their first attempt. However, about 30% of the invited candidates did not appear for the exam. Characteristics of successful candidates were being young and being among the seniors with the least clinical experience. Most had specialized in internal medicine and had completed their observation period in a non-academic hospital. There they had received somewhat more attention than those who had been in academic hospitals. Significantly, the successful candidates were more proficient in Hebrew than the unsuccessful candidates, and reported no special problems during the observation period.
