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.

Pulmonary embolism is a common event in hospitalized patients. In some cases it presents with hemodynamic collapse, indicating massive obliteration of the pulmonary vasculature and has a very grim prognosis; 2/3 of such patients die within 2 hours of onset of symptoms. We describe our experience in 13 patients with massive pulmonary embolism. An aggressive diagnostic and therapeutic approach, utilizing sophisticated imaging techniques, thrombolytic therapy and surgery, led to the survival of 8 of the patients. Our experience supports an aggressive approach in these seriously ill patients.

Secondary malignancy is a well-recognized complication of radiation therapy. The risk of postirradiation sarcoma in long-term follow-up is 0.03-0.8%. We report a case of radiation-induced perisacral angiosarcoma 6 years after pelvic irradiation for sigmoid cancer in a 77-year-old man. The tumor was diagnosed postmortem and was locally advanced and metastatic. He died 6 months after onset of symptoms. This case demonstrates the importance of long-term follow-up in those given radiotherapy.

Health care workers are at continuous risk of hepatitis B infection. Currently recommended intramuscular vaccination confers immunity in only 85-90%. We examined the immunogenicity and safety of intradermal vaccination of hepatitis B vaccine in nonresponders. 400 hospital employees who had been immunized as recommended were screened for anti-HBs antibodies and 50 were found seronegative. Each received an intramuscular booster injection and antibody level was measured a month later. Excluded were 33 employees, including 24 late responders, 2 HbsAg carriers and 7 uncooperative employees. 17 employees (mean age 47.1 yrs) then received a series of 3 intradermal injections of Energix B, 0.25 ml in the forearm, 2-3 weeks apart. The mean number of previous intramuscular injections was 4.6±1.4 month later there was a mean titer of 315.4±347.0 miu/ml of antibody in 16/17 workers. Side effects were minimal. Intradermal injection of hepatitis B vaccine for nonresponders seems effective for inducing seroconversion. Its cost-effectiveness for the health care system warrants assessment.

Splenic cysts are rarely found or diagnosed. Excluding cases of trauma, the events preceding their development have not been fully understood. We describe a 22-year-old woman in her 34th week of pregnancy in whom ultrasound revealed a cystic lesion 8610 cm. in diameter in the left upper abdomen. Further imaging tests followed by laparotomy confirmed the splenic origin of the cyst. Splenectomy was performed and the lesion was histopathologically defined as an epidermoid cyst.

The aim of this study was to determine whether testicular volume can serve to predict patterns of spermatogenesis in azoospermia. In 27 tests of azoospermic infertile men, cytological specimens from several sites from each testis were obtained by fine needle aspiration. Testes were classified according to the most mature spermatogenic cell type. Classifications were testes with spermatozoa, with arrested spermatogenic development, and with only Sertoli cells. Prior to fine needle aspiration the 3 dimensions of each testis were determined ultrasonically and its volume calculated. Mean testicular volume (±‏SD) was 7.71 (±5.95) ml for testes with spermatozoa and 7.55 (±2.35) and 7.31 (±4.42) ml for testes with spermatogenic maturation arrest and with only Sertoli cells, respectively (differences not significant). It is concluded that testicular volume can not be used as a predictive parameter, neither for the presence of spermatozoa nor for the cytological pattern of the testes of azoospermic infertile men.

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.

Insufficiency fractures of the pelvis may be overlooked as a cause of hip or groin pain. These fractures occur in the elderly, usually those with pronounced osteopenia of the pelvis. Predisposing factors include corticosteroids, local irradiation and postmenopausal osteoporosis. These fractures are difficult to detect clinically and plain radiographs and other studies may be misleading, delaying diagnosis and treatment. A 65-year-old woman had left groin and hip pain for 2 months with no history of trauma. Plain radiographs showed lytic lesions in the left pubic rami. Bone scan revealed increased uptake in that region, suggesting metastatic bone disease. Computed tomography and magnetic resonance imaging demonstrated fractures in the left superior and inferior pubic rami, with callus formation with no involvement of soft tissues. Quantitative computed tomography indicated low calcium concentration, below fracture threshold. The diagnosis of insufficiency fractures of the pelvis was confirmed by the favorable clinical and radiographic outcome. It is therefore important to be familiar with the appearance and location of these fractures.

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.

Acute post-traumatic spinal injury is common and usually poses no diagnostic difficulties. Following a low-energy fall, the onset of acute central cord syndrome in the elderly is not common and is frequently misdiagnosed. Men aged 60 and 81, and a woman aged 75 are described, in whom central cord syndrome was overlooked. Awareness of this condition is important to avoid incorrect diagnosis and hazardous management.

Airbag-Associated Ocular Trauma

Ophthalmology Dept., HaEmek Medical Center, Afula

Airbags have received widespread recognition as an effective means of enhancing automobile safety. They are particularly effective in frontal and front angle collisions which otherwise would be fatal or cause serious injuries. Inflation of the bag helps protect the driver and front-seat-passenger from hitting the steering wheel, dashboard or windshield. In frontal crashes airbags have reduced driver deaths, hospital admission rates, and incidence of brain injury. On the other hand, an increasing variety of airbag-associated organ injuries has been reported, including blunt ocular and chemical trauma. 2 cases of ocular trauma due to airbags which resulted in choroidal rupture with disastrous outcome in terms of visual acuity are presented. Since the very first report in May 1991 of airbag-associated ocular trauma until June 1996, there has apparently been only 1 case of choroidal rupture due to airbag-associated trauma, presented in 1 sentence of a brief report. Although airbag-related eye trauma may be relatively infrequent, the severity of the injuries incurred, especially when the posterior segment of the eye was involved, warrants research on new airbag design that minimizes the risk of ocular injury. Meanwhile all cases of airbag-associated ocular trauma should be reported, so that medical staff, the general population and car manufacturers will become more aware of this medical issue.

Senior surgeons were asked about mandatory participation of general surgery residents in the advanced trauma life support (ATLS) course. Although trauma care in Israel is given by surgical residents, in the opinion of their senior mentors the course should continue to be mandatory for them.

In this era of antimicrobial medication, intracranial complications following otitis media are rare. We present a 5-year-old boy who suffered from petrositis (Gradenigo syndrome) and cavernous sinus thrombosis as combined complications of acute otitis media caused by fusobacteria. The diagnosis was made using imaging methods suited to the various structures of the skull. Cure was achieved by prolonged conservative treatment with antibiotics, with gallium scan for evaluation of the bone inflammation.

Hemato-oncology patients needing mechanical ventilation for acute respiratory failure (ARF) have an extremely poor prognosis, with a mortality of more than 90%. Over an 18 month-period 17 such patients were admitted to our ICU. Diagnoses included leukemia (11 cases), lymphoma (1), and status post bone marrow transplantation for leukemia, lymphoma or breast cancer (5). Of 8 whose ARF was associated with septic complications due to neutropenia following chemotherapy, 6 survived. Of 9 who developed ARF due to toxic damage to vital organs following high-dose chemotherapy, 2 survived. Those who develop ARF during chemotherapy are expected to have an increase in granulocyte count within days, and have a surprisingly good prognosis. They should be admitted to the ICU and treated aggressively. Those who develop sepsis due their primary disease and whose general condition contraindicates chemotherapy, have an extremely grave prognosis and admission to the ICU may not be warranted.

We determined spermatogenic patterns of seminiferous tubules in azoospermic infertile men and evaluated the prevalence of bilateral testicular homogeneity. 185 azoospermic men underwent bilateral testicular fine-needle aspiration (TFNA) in which each testis was punctured at 3 different positions. Aspirated material was stained and classified according to the most mature spermatogenic cell type present or whether only Sertoli cells were present. 35.7% had spermatozoa in their testes, 36.2% had spermatogenic maturation arrest, and 28.1% had only Sertoli cells in their seminiferous tubules. In 15.6% of all patients, the diagnosis in 1 testis differed from that in the other. In only 73.2% of those with testicular spermatozoa was it bilateral. In the remaining 26.9%, only Sertoli cells, spermatocytes or spermatids were found as the most mature cell type in the other testis. The study definitely indicates that fertilization with retrieved testicular spermatozoa should not be offered to azoospermic patients without prior evaluation of the seminiferous tubue spermatogenic pattern in both testes.
