Follicle-stimulating hormone (FSH) is considered to be the most important plasma hormone correlated with spermatogenesis. Elevated FSH plasma levels were shown to be associated with complete damage to testicular seminiferous tubule germinal epithelium. Recently, there have been conflicting reports with regard to the value of FSH plasma levels in predicting seminiferous tubule histology in the azoospermic patient and hence, as a guide for therapy in assisted reproduction using testicular sperm retrieval. The aim of this study was to evaluate whether FSH plasma levels can predict spermatogenic pattern in the testes of the azoospermic infertile patient. 69 infertile men with non-obstructive azoospermia and 18 with very severe oligospermia were studied. In all, plasma levels of testosterone, free testosterone, prolactin, luteinizing hormone and follicle-stimulating hormone were measured by enzyme immunoassay. In the azoospermic patients the seminiferous tubule spermatogenic pattern was determined in testicular aspirates obtained by multiple fine needle aspiration and categorized according to the most mature spermatogenic cell type in the aspirates: Sertoli cells only, spermatogenic maturation arrest or full spermatogenesis. There were no significant differences in plasma levels of any hormone measured except in very severely oligospermic and azoospermic patients. Both normal and elevated levels were detected in all, regardless of seminiferous tubule cytological pattern or plasma FSH in azoospermic patients. It is concluded that plasma levels of FSH can not be used as a predictive parameter, neither for the presence of spermatozoa nor for any other seminiferous tubule cytological pattern in azoospermic infertile men. They cannot serve as guides for selection of azoospermic men for trials of testicular sperm retrieval in assisted reproduction.

Trisomy 18 is a chromosomal disorder giving multiple anomalies. Its frequency depends on maternal age. We report a 28-year-old woman in her first pregnancy, who underwent first trimester scanning for screening. Due to increased nuchal translucency and exomphalos, chorionic villous sampling was performed. Cytogenetic diagnosis was trisomy 18 and termination of pregnancy was carried out immediately.

Primary health care physicians have a pivotal role in treating mental health problems. We determined the proportion of primary care physicians in Israel who treat depression and their characteristics. The study was based on a stratified national random sample of primary care physicians (n677, response rate 78%). From these physicians' reports 22% always treat depression, 36.6% usually, 28.6% sometimes, and 12.6% never. Based on a logistic regression model the physicians who always or usually treated depression were distinguished from the other physicians by their treating more medical conditions on their own, seeing themselves as having more first contact for psychosocial problems, having frequent contact with social workers and specializing in family medicine. Primary health care physicians play a major role in treating depression on their own. This raises new questions about how they treat depression themselves, and under what circumstances they treat or refer to a specialist.

Studies over the past 30 years have shown a relationship between folic acid deficiency and psychopathology. FA deficiency was observed more often in depressed and in psychotic patients, in alcoholics, in those suffering from organic mental disorders and in the psycho-geriatric population. In a chronic inpatient population of 120 patients, of the 106 in whom FA serum levels were examined, only 1 had a definitely subnormal level. An additional 16 had close to the lower limit of normal (2 ng/ml) and were considered borderline cases. FA-deficient and borderline patients were then compared to matched patients with normal FA levels on the MMSE and PANSS scales by blinded raters. Small differences were found between the 2 groups. The FA-deficient and borderline patients had more organic and psychotic symptoms, but the differences were not statistically significant.

Takayasu arteritis is an uncommon vasculitis, often referred to as aortic arch syndrome. It is most prevalent in young women. Physical findings such as the combination of pulseless arms and carotid bruits suggest the diagnosis. Associated skin manifestations such as pyoderma gangrenosum and erythema nodosum have been described. We present a 27-year-old woman with diffuse purpuric eruption and Takayasu arteritis. This appears to be the first description of such an association.

Results of laboratory tests ordered during a primary care encounter may reveal findings of abnormal liver function tests, including elevated liver enzymes, hyperbilirubinemia, hypoalbuminemia or abnormal coagulation tests. The object of this study was to describe the spectrum of these liver function test (LFT) abnormalities in primary care.

Results of all laboratory tests ordered during 10 months in an urban primary care clinic were retrospectively reviewed and the medical charts of patients with abnormal LFTs were studied. In 217/1088 (20%) of the tests at least 1 LFT abnormality was found in 156 patients. New diagnoses were made in 104 patients. The main diagnostic groups were: non-alcoholic fatty liver changes, Gilbert's disease, acute infectious hepatitis, alcoholic liver disease and cirrhosis and hepatotoxic drug injury. In 60 patients the physician classified the abnormality as negligible and not associated with significant disease. However, an abnormal test that had been ordered for evaluation of a specific complaint, was indeed likely to represent significant disease (X²=29.5, p<0.001). We conclude that finding abnormalities in liver function tests is common in the primary care clinic but does not often indicate significant liver disease.

Trichobezoars are accumulations of hair casts in the stomach associated with trichophagia. The typical patient is an adolescent female who presents with alopecia and an upper abdominal mass which on moving can cause intermittent gastric outlet obstruction. Only a minority of patients have severe psychiatric disorders. When hair strands extend from the main mass in the stomach, all along the small bowel and reaching the cecum, the condition is termed the Rapunzel syndrome. In about 5% of patients there are separate hair masses in the stomach. The clinical presentation includes abdominal pain, loss of appetite, weight-loss, vomiting, loose stools, pancreatitis, jaundice, anemia and hypoalbuminemia. These signs and symptoms raise the suspicion of malignancy. Complications of bezoars include ulcers, perforation of the bowel, obstruction and intussusception. Diagnosis can be established either by barium swallow or by CT scan. Ultrasound might suggest the diagnosis, but sonographic features are definitely not pathognomonic. Treatment is surgical, as endoscopic removal is usually unsuccessful. We present 2 children in whom trichobezoars were found.

Pheochromocytoma usually presents with nonspecific symptoms such as headache, palpitation, chest pain and hypertension. We present a 48-year-old woman hospitalized due to a pheochromocytoma multi-organ crisis (PMC). It consists of a tetrad of symptoms: multi-organ failure, hyperthermia, encephalopathy and unstable blood pressure. Distinguishing PMC from septic shock may be difficult, and requires needs a high clinical index of suspicion.

Facial synkinesis is an involuntary activation of muscles innervated by the zygomatic or mandibular branche of the facial nerve in conjunction with voluntary activation of the other branch. It appears frequently after recovery from peripheral facial nerve paralysis. We report 10 patients with facial synkinesis following Bell's palsy with a mean duration of synkinesis of 7±4 years before treatment with periorbital injections of Botulinum toxin type A. 9 had marked subjective and objective improvement starting a few days after injection andlasting 4-9 months. The results suggest a useful treatment option for post-Bell's palsy facsynkinesis with Botulinum toxin type A.

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.

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.

Cryosurgery is an old technique which is being used for hepatic tumors as an adjuvant to hepatic resection. We recently treated 7 patients with multiple malignant liver tumors, 5 of whom had colorectal metastases, 1 carcinoid metastases, and 1 multiple hepatic lesions of hepatocellular carcinoma. 6 underwent combined liver resection and cryoablation of lesions in the remaining liver. In the 7th patient, only cryoablation was performed because hepatic resection was rejected and there was an extrahepatic metastasis. The advantages of this treatment are removal or destruction of all liver lesions found by any method, including intraoperative ultrasound examination, maximal preservation of normal liver parenchyma and that it is curative in patients inoperable by standard criteria.

Mechanism of Primary Hypertension

We review various theories of the pathogenetic mechanisms of steroid-induced and essential hypertension. We investigated the possibility that a pathogenetic mechanism leading to glucocorticoid (GC)-induced hypertension or to mineralocorticoid (MC)-induced hypertension, or both, may be of critical importance in primary hypertension. We studied plasma levels of corticosterone (BK) and aldosterone (Aldo), and their concentrations in arterial and renal tissues of spontaneously hypertensive rats (SHR), a model of primary hypertension, and in the antecedent strain WKY rats as a normotensive control. Plasma levels of BK and Aldo were found to be normal and identical in SHRs and WKYs. Tissue (intracellular) levels of BK were more than double in SHRs than in WKYs. Subsequently we examined the activity of 11b-hydroxy steroid dehydrogenase (11-HSD) in both aortic and renal tissues of SHRs and WKYs. 11-HSD converts BK to the corresponding 11-keto compound, 11-dehydro-corticosterone (cpd.AK), which is inactive, in view of its inability to bind to the MC receptors (and also to the GC receptors). BK, the main glucocorticoid in the rat, as well as cortisol, have high affinity for the MC-receptor (MR). Normally BK or cortisol are present in 10²-10³ times greater concentrations than Aldo in tissues possessing MR. The enzyme 11-HSD deactivates BK (or cortisol), thus protecting MC-receptors in the MC target tissues from being activated by GC. When we examined arterial and renal tissue activities of 11-HSD in SHRs, the activity of 11-HSD was only one-third that found in the WKY rats. This explained higher levels of BK in the tissues of SHR, and suggested that decreased activity of 11-HSD is a pathogenetic factor for hypertension in SHRs.

Thus, in a model of primary hypertension such as SHR, decreased activity of 11-HSD in the target tissues of MC appears to lead to glucocorticoid-induced mineralocorticoid hypertension.

6 cases of popliteal vascular trauma are presented, 3 due to posterior dislocation of the knee and 3 due to crush injury. The patients were referred from another hospital and some had undergone unnecessary angiography when ischemia was present, leading to delay in surgery. All patients presented with distal ischemia and underwent reconstructive surgery; 2 subsequently underwent below-knee amputation because of irreversible ischemia and sepsis.

Urgent operation for popliteal vascular trauma is necessary whenever there is ischemia and intraoperative angiography may be necessary. There should be reconstruction of the artery and vein when there is concomitant venous damage, and fasciotomy and debridement are important. The harmful potential of occult popliteal vascular injuries and their ostensible mild presentation present a challengfor the emergency room surgeon.

Interest in, and use of alternative medicine has increased in the past few years in Israel. Still, little is known about the extent to which it is utilized, the more common treatments, patterns of use, and its influence on the conventional primary care system. We surveyed a kibbutz community to determine prevalence and patterns of use of alternative medicine and satisfaction with the outcome. The entire kibbutz population was asked to fill out a questionnaire (parents answered for their children). They were questioned as to their use of alternative medicine in the previous 5 years, types and dates of treatment, duration of treatment, and whether it had helped.

Of 1044 subjects, 830 responded (79.5%). 16.4% had used alternative medicine at least once in the previous 5 years. Of these, more than a 1/4 were treated by 2 or more types of alternative therapy. About 2/3 of those responding were women. Most had muscle-skeletal (36%), upper respiratory and/or atopic problems (19.3%). The most common treatments were homeopathy (31%) and acupuncture (20%). In approximately 2/3, the treatment was considered helpful, and either solved the problems or gave long-lasting improvement. 70% of those who used alternative medicine were treated within the previous 15 months and about 40% within the previous 3 months. The use of alternative medicine is increasing and it is now includein standard medical services. Most of those who used alternative therapy felt is hadhelped.
