Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired disorder of blood cells which originate from an abnormal hematopoietic stem cell. The condition is characterized by nocturnal hemoglobinuria, chronic hemolytic anemia, and thrombosis. We describe a 60-year-old woman with PNH admitted with abdominal pain and jaundice, who had dark urine on arising after a night's sleep. The diagnosis was established by the typical clinical story and a positive Ham test. She was successfully treated with Halotestin and folic acid. Although PNH is rare, it should be considered in the differential diagnosis of hemolytic anemia. Early diagnosis and treatment are important.

During 1987-1996, 39 of 720 patients hospitalized (most for severe schizophrenia) were diagnosed as having active pulmonary tuberculosis (5.4%, 975 per 105 per year). In 1992-1993, after a cluster of 5 cases was found, all patients were screened by PPD skin test and chest X-ray and 16 more cases were identified. Diagnosis was confirmed bacteriologically in only 10 of them but there were typical radiological findings in the others. 39 were treated with a multi-drug regimen. In addition, 333 exposed patients and 21% who had converted their skin tests were given isoniazid preventive therapy. A small increase in levels of liver enzymes was common, but significant abnormality (over 4 times the upper limit of normal) was found in only 7 patients, in whom therapy was therefor stopped or changed. During a follow-up period of 4 years, 2 more developed tuberculosis and 33 converted their PPD reactivity status. We conclude that an outbreak of tuberculosis in a psychiatric hospital can be controlled with a relatively low rate of side-effects by using systematic diagnostic and therapeutic measures. However, single step screening is not sufficient. Routine screening of all new patients, a high index of suspicion and contact investigation are needed.

Forearm bone fractures are commonly the result of falling on the outstretched hand or of direct injury. The preferred treatment is debated. The possible modalities are: application of a cast, often necessitating repeated manipulations; open reposition and fixation by plates and screws; or closed manipulation and closed intramedullary nailing. We present our favorable results in treating these fractures in young patients by closed intramedullary nailing, and compare them with the unfavorable results of this method in mature adults.

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.

During 1971-1996, 17 patients with mixed mesodermal uterine tumors were treated. Average age at diagnosis was 67.3 years, 12/17 were of European and 5/17 of Afro-Asian extraction. The overall 5-year survival was 21%. 10/17 patients had mixed mesodermal tumors with a heterologous mesenchy-mal element, and 7/17 had a homologous mesenchymal element (carcinosarcoma). 6/17 had another primary malignancy, including breast cancer (3/17), bilateral metachronous breast tumor (2/17), and malignant lymphoma of the neck region (2/17). All 3 with breast cancer had previously been treated with tamoxifen. 1 had simultaneous mesodermal tumor and ovarian thecoma. Simultaneous autoimmune manifestations occurred in 2/17, including thrombocytopenic purpura in 1, and myasthenia gravis in another. Mesodermal tumor of the uterus is a relatively rare malignancy with aggressive behavior and poor prognosis. It also had unusual associations with other primary tumors, hormonal treatment, and autoimmune manifestations.

We evaluated the efficacy of ciprofloxacin eardrops compared to tobramycin and to a placebo in the treatment of chronic suppurative otitis media. 60 ears were randomly assigned to treatment for 3 weeks with ciprofloxacin, tobramycin or placebo eardrops. The organism most commonly isolated from the ear discharge was Pseudomonas aeruginosa. The clinical responses were 78.9% and 72.2%, respectively, in the ciprofloxacin and tobramycin groups, while it was only 41.2% in the placebo group. Treatment with ciprofloxacin eardrops seemed to be at least as efficient as treatment with tobramycin. Considering the lack of ototoxicity of ciprofloxacin, this treatment may be best for chronic otitis media.

Very-low-birth-weight premature infants are at high risk for invasive candidiasis. The most commonly involved organ is the kidney. Renal candidiasis may present as fungus-ball obstructive uropathy. We describe unilateral renal obstruction secondary to fungus-ball in a premature infant. Noninvasive, systemic antibiotic treatment, including amphotericin B and fluconazole, resulted in disappearance of the finding.

Radio-frequency (RF) current has been used successfully to ablate normal human tissue. To investigate further the clinical application of this modality in tumors, we studied the potential of using RF percutaneously to destroy experimental kidney tumors. 35 outbred albino rabbits underwent direct-implantation of renal VX2 tumor during open surgery. After 21 days, ultrasonography was performed to show tumor presence and size. A shielded RF needle was designed to be inserted percutaneously through an introduction needle. An electrical insulation shield covering the RF needle was retractable, controlling the length of exposure of the RF needle inside the tissue. 22 days after tumor implantation, RF was applied via this special needle using a ZoMed International RF generator. In one group of rabbits the procedure was performed under direct vision during open surgery, while in another group treatment was percutaneous, the needle guided by palpation of the tumor. Rabbits were killed 3 days later and revealed 4-25 mm intra-tumoral RF-induced lesions. A direct relation was found between lesion size and the power and duration of RF applied (at 7.5 W, R=0.48, and P=0.32). Based on our preliminary results we can conclude that RF may have clinical applications in the near future for percutaneous local tumor control in parenchymal organs.

A prospective study of the effect of cataract extraction with intraocular lens implantation on the course of diabetic retinopathy (DR) in 44 patients (59 eyes) was carried out. It showed that in the 1-3 years following surgery, there was progression of DR (including development of newly formed retinopathy) in 35% of the patients (28.8% of eyes). Progression was more marked in patients with pre-operative bilateral DR compared to those without bilateral DR (77% and 16% respectively). Insulin dependence did not play a role in progression. Final visual acuity was better in patients without pre-operative DR, as well as in eyes without progressive retinopathy.

Trauma registry is vital for every trauma center. In 1995, data on all injured patients who reached our trauma unit were collected. 3.040 patients were hospitalized, of whom 415 were transferred from other hospitals. We describe the distribution of the patients to in-patient wards and present the relationship between mortality and injury severity score. 1102 hospitalized patients underwent a total of 1599 operations with an overall mortality of 2.63%.

Subclavian vein thrombosis accounts for approximately 1-2% of recorded deep venous thromboses. It may be primary or secondary, and insertion of a central venous catheter is the most common cause of secondary subclavian vein thrombosis. Traumas, anatomic abnormalities and carcinoma are important additional risk factors for secondary thrombosis. Primary thrombosis of the subclavian veins is known as Paget-Schroetter syndrome. New criteria for its diagnosis include a history of increased upper extremity use prior to onset of symptoms, the presence of a venographically demonstrated thrombus and absence of any definable causes. We describe a 42-year-old woman with a history of intensive physical exertion admitted with swelling, pain and difficulty moving her arm. The diagnosis of primary subclavian vein thrombosis was established from the history of physical effort, results of Doppler ultrasound, and exclusion of other causes of subclavian vein thrombosis. This case suggests that primary subclavian vein thrombosis should be considered in young patients with subclavian vein thrombosis after exclusion of secondary disease.

Evolving Role of Radiation Therapy in Nonmalignant Disorders

Rami Ben-Yosef

Bone Marrow Transplant Dept., Hadassah Hospital, Jerusalem

Various nonmalignant disorders have traditionally been treated with radiation therapy. It has almost completely been discontinued due to reports of secondary malignancy. During the past 15 years there has been an evolving role for radiation therapy in various nonmalignant disorders such as meningioma, A-V malformation, prevention of vascular restenosis and heterotopic bone formation. Appropriate follow-up of such patients for diagnosis of secondary malignancy is recommended. Radiation therapy should be carefully considered in diseases not successfully treated with conventional means.

The Treatment of Mentally Sick Persons Law of 1955, was repealed and replaced by the Law of 1991. Under the latter, the Order for Compulsory Ambulatory Treatment (OCAT) was addressed for the first time (Section 11, a-d). According to this law, the district psychiatrist instead of issuing a hospitalization order, may issue an OCAT, under which the required treatment is given within the scope of a clinic which he designates, for up to 6 months and under conditions which he specifies. This is done on the basis of psychiatric examination, or an application in writing from the director of a hospital or clinic, when continued ambulatory treatment is needed after discharge from hospital or instead of compulsory hospitalization. The district psychiatrist may extend the period of treatment for further periods, none of which is to exceed 6 months. Compulsory ambulatory treatment is to enable patients to benefit from the positive aspects of living freely in the community, while receiving prompt treatment under compulsory conditions. The concept offers a partial solution, achieving a balance between civil liberties and clinical needs, between over-confinement and under-treatment which might be dangerous or neglectful. The clinical impression has been that the OCAT has not fulfilled expectations. The purpose of this study was to examine the topic in a systematic way in Jerusalem and the soutern districts for the 4 years since inception of the law. In 44.4% of cases OCAT was proven to be effective, while in 33.1% it was found to be ineffective and did not prevent compulsory hospitalization, one of its main goals. It was partially effective in the rest of the cases. It is recommended that suitable means for the enforcement of the law be allocated and that the subject of forceful hospitalization and OCAT be made a mandatory subject in the residency program of psychiatrists.

112 patients with localized prostate cancer, clinical stage A2-C, were treated by definitive radiotherapy between 1982-1988. Radiation volume encompassed the prostate, seminal vesicles and pelvic lymph nodes. The 10-year actuarial survival figures were: overall 51%; stage A2 87%; stage B 50%; stage C 36%; well differential tumors 67%; moderately differentiated 50%; poorly differentiated 32%; patients with local tumor control 55%; and patients with minimal local control 36%. It is concluded that external beam irradiation is effective in localized prostatic cancer. Stage and grade are prognosticators of survival.
