Cerebrovascular events have high mortality and morbidity, especially in the elderly. Ischemia is the main cause and 30% of the ischemic events are embolic and of cardiac origin. The clinical picture is not always typical of the type of stroke, but diagnosis of the mechanism of the event determines treatment. Transesophageal echocardiography (TEE) is a sensitive procedure more appropriate for diagnosing emboli of cardiac origin than transthoracic echocardiography (TTE). We therefor compared TEE and TTE in the determination of the source of emboli in 65 patients with ischemic stroke but without significant atherosclerotic changes in their carotid arteries, and compared these findings with those in 50 patients without stroke. 68% of the patients had potential sources of emboli according to TEE, compared to only 15% according to TTE. In the control group only 24% had potential sources of emboli by TEE. The findings were: clots in the left atrium, severe aortic atheroma, patent foramen ovale with paradoxical shunt, spontaneous echocardiography contrast, vegetations and mitral valve prolapse. The study showed that TEE is better than TTE in detecting the etiology of embolic stroke in those with normal carotid arteries, thus determining appropriate management.

Urinary bladder carcinoma with trophoblastic differentiation (TD) is a variant of urothelial (transitional cell) carcinoma (TCC) which secretes placental proteins, predominantly beta-human chorionic gonadotropin (HCG). An aggressive clinical course and a poor prognosis are characteristic of this tumor. We evaluated the frequency and clinical and pathological appearance of TCC-TD in the Upper Galilee and Golan Heights between 1988 and 1995 inclusive. Beta HCG, human placental lactogen (HPL), pregnancy specific beta-1 glycoprotein (SP-1) and placental alkaline phosphatase were determined immunohistochemically in paraffin-embedded TCC of urinary bladder. Tumor grade, stage and patient survival were also determined. There was beta-HCG immunostaining in 13 of 62 cases (20.9%). TD was correlated with higher grades of TCC and with advanced stages of disease. No cases of TCC-TD were found in grade 1, stage 0. Co-expression of beta-HCG and HPL was displayed in 2 cases, beta-HCG and SP-1 in 9, and beta-HCG, HPL and SP-1 in 2. Disease-free survival and overall survival were shorter in TCC-TD.

Ecstasy is a stimulant used mainly by youngsters to get 'high.' There are few reports of acute injury of the liver due to ecstasy. We describe a 37-year-old woman who presented with the clinical picture of recurrent hepatitis following ingestion of the drug. After several months she developed liver cirrhosis shown by biopsy and CT scanning. This case emphasizes the potential danger of ecstasy. Every patient with hepatitis of unknown origin must be questioned about ingestion of the drug.

Continuous Quality Improvement in Anesthesia

Slow continuous quality improvement (SCQI) in anesthesia is a process that allows identification of problems and their causes. Implementing measures to correct them and continuous monitoring to ensure that the problems have been eliminated are necessary. The basic assumption of CQI is that the employees of an organization are competent and working to the best of their abilities. If problems occur they are the consequences of inadequacies in the process rather that in the individual. The CQI program is a dynamic but gradual system that invokes a slower rate of response in comparison with other quality methods, like quality assurance. Spectacular results following a system change are not to be expected an the ideal is slow and continuous improvement.

A SCQI program was adapted by our department in May 1994, according to the recommendations of the American Society of Anesthesiologists. Problem identification was based on 65 clinical indicators, reflecting negative events related to anesthesia. Data were collected using a specially designed computer database. 4 events were identified as crossing previously established thresholds (hypertension, hypotension, hypoxia and inadequate nerve block). Statistical process control was used to establish stability of the system and whether negative events were influenced only by the common causes. The causes responsible for these negative events were identified using specific SCQI tools, such as control-charts, cause-effect diagrams and Pareto diagrams. Hypertension and inadequate nerve block were successfully managed. The implementation of corrective measures for the other events that cross the threshold is still in evolution. This program requires considerable dedication on the part of the staff, and it is hoped that it will improve our clinical performance.

Verapamil-Associated Liver Injury

Hepatotoxicity due to verapamil is very rare and to the best of our knowledge only 10 cases have been reported. A 54-year-old woman developed cholestatic liver injury and pruritus following treatment with sustained-release verapamil (240 mg/day) for arterial hypertension. The pruritus and all hepatic biochemical abnormalities completely resolved after withdrawal of the drug. Similar to previously reported cases, the pathogenic mechanism of verapamil-associated liver injury in our patient was, most probably, idiosyncratic. These cases emphasize the need for awareness of the possibility that verapamil may occasionally induce liver injury, sometimes severe and potentially fatal.

We determined whether a single testicular specimen is sufficient to represent qualitatively the spermatogenic process within the testes of azoospermic or severely oligospermic infertile men. In 191 testes of azoospermic patients and in 26 of those with severe oligospermia, fine needle aspirations at 3 different sites of each testis were performed. Aspirated material from each puncture was stained and in each smear all spermatogenic cells, as well as Sertoli cells, were identified. Testes were classified according to the most mature spermatogenic cell type present, or the presence of only Sertoli cells. The homogeneity of the testicular spermatogenic process was then evaluated. There was an overall intratesticular difference between aspirates in 14.1% of azoospermic testes and in 26.9% of severely oligospermic testes with regard to the most mature spermatogenic cell type. When spermatozoa were the most mature cell type, they were detected in all of the 3 aspirates in 71.4% of the testes. In 18.4% or 10.2% of this group of testes they were retrieved in only 1 or 2 of the aspirates, respectively. In testes in which spermatids or spermatocytes were the most mature spermatogenic stage, these cell types were detected in all 3 aspirates in only 36.4% and 68.0%, respectively. In azoospermic patients with full testicular spermatogenesis, the likelihood of retrieving spermatozoa from the testes was 84.3%, 92.7% and 100% in 1, 2 and 3 specimens, respectively. The following conclusions were drawn: There is a wide range of testicular heterogeneity in azoospermia or very severe oligospermia for diagnosing the testicular spermatogenic pattern. In azoospermia, specimens from several testicular sites are required. It is strongly recommended that no assisted fertilization be offered to azoospermic patients unless prior evaluation of the spermatogenic pattern in the seminiferous tubules is determined.

In a study examining the relationship between patient participation in clinical decision making and levels of anxiety, patients were offered a choice of treatment for ureteral calculus. 42 received information about 2 treatment options, ultrasound fragmentation of the stone through a ureteroscope and extracorporeal shock wave lithotripsy (ESWL), and were asked to choose the method that they preferred. 54 received treatment decided on by the physician without their participation in the decision making process. Anxiety was measured before meeting with the physician, immediately after the meeting and on hospitalization for treatment. The contribution of the patient's perception of participation in the decision- making process and level of education was also examined. There was a decrease in level of anxiety after meeting with the physician only among those who did not actually participate in the decision-making process (p<0.05). There was no change in the level of anxiety among those offered choice of treatment. However, a decrease in anxiety was evident among patients who perceived that they had received information about their illness and its treatment (p<0.01). This was not the case for patients who perceived themselves as participants in decision making unless they had a relatively high-level of education (p=0.05).

Erythromycin is considered the drug of choice in the treatment of streptococcal pharyngitis in patients allergic to penicillin. However, in recent years several publications, especially in Finland and Italy, showed high resistance rates of S. pyogenes isolates to erythromycin and other new macrolides. To evaluate the situation in Israel, we checked the MIC of isolates from patients with tonsillitis during 1996. E-test results showed an MIC-50 of 0.23, 0.13 and 0.47 mcg/ml for erythromycin, clarithromycin and roxithromycin, respectively and a MIC-90 of 0.37, 0.23 and 0.78 mcg/ml. Only 2 isolates (2.1%) were partially or completely resistant to all 3 antibiotics. We conclude that empiric therapy with macrolides in Israel is still a viable option and can be recommended in S. pyogenes tonsillitis for patients allergic to penicillin.

Suprascapular Nerve Entrapment in a Basketball Player

A basketball player was shown to have a suprascapular nerve lesion without any history of shoulder girdle trauma. This acute neuropathy, never previously described in basketball players, is a result of repeated micro-trauma, due to nerve traction over the coracoid notch during violent movement ("dunking" most probably). Clinically, he was unable to abduct his arm and had some difficulty in external rotation. He developed atrophy in both the supra- and the infraspinatus muscles. Nerve conduction latency to the supraspinatus muscle was 8.0 ms, and to the infraspinatus, 8.5 ms. The compound muscle action potential registered in the supraspinatus was 1.224 mV, and in the infraspinatus, 1.237 mV. After 3 weeks of inactivity, recovery was spontaneous and practically complete.
