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.

We examined the long term results of vertical banded gastroplasty 3-10 years after operation. They were assessed by weight lost, incidence and severity of untoward effects and improvement in diet and in quality of life in 75 of 122 who had had the operation. Average weight lost was 28.5±14.9 kg (p<0.001) in 5 years and 58.6±30.4% of excess weight, which brought patients to within 32±25.2% of ideal weight. According to these measures, in 63-76% the operation had been successful in causing weight loss. The 2 criteria for successful weight loss were loss of more than 50% of weight in excess of ideal body weight and residual body weight less than 50% greater than ideal body weight. There was a greater risk of failure in unmarried subjects older than 45 (odds ratio for not losing weight was 6; in those weighing more than 120 kg it was 9). We saw evidence of this mostly 4 years after operation (odds ratio 11). The degree of success in weight loss was correlated with texture of food (softness) preferred and length of operation. Of those interviewed, only 65% were satisfied with their results. The greatest improvement in quality of life measurements was in physical activity, perception of health, and frequency of feeling depressed. Side-effects were vomiting, reflux and fatigue. Only 34.7% were able to digest solid foods, so that subjects are at risk for nutritional deficiencies.

Six Cases of Acute Rheumatic Fever in One Year

George Habib, Ramiz Abu-Ahmad

Rheumatology Clinic and Dept. of Medicine, Nazareth Hospital; and Medical Dept. B, Carmel Medical Center, Haifa

During 1995, 6 cases of acute rheumatic fever were diagnosed here. Taking into account differences in total admissions, this appears to represent an increase over 1994. Most of the cases were males, with average age at diagnosis 19.5 years. All were of low socioeconomic status. 50% had cardiac involvement, and 1 needed treatment with corticosteroids. Most had pharyngeal symptoms prior to the acute attack, and 1 patient had 2 prior episodes of rheumatic fever. A thorough epidemiological study should be done in the Nazareth area to assess the real incidence of acute rheumatic fever, and to determine whether there is a true increase in incidence.

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.

Patients' opinions of the role of the primary care physician were studied. The study population consisted of Hebrew-speaking members of the Clalit Sick Fund, aged 18+, who visited primary care and specialty clinics. Interviews took place during January-March 1995 in the Emek and Jerusalem, and during August-October 1995 in Beer Sheba. A total of 2,734 interviews were conducted, and the response rate was 88%. 64% of the respondents preferred the primary care physician as the first address for most problems occurring during the day. Multivariate analysis revealed that the variables predicting this preference were: being over age 45, having completed less than 12 years of schooling, being satisfied with the physician, and when a child's illness was involved. Whether the physician was a specialist had only a marginal effect. The findings also show that among those who did go directly to a specialist for the current visit, 49% would still prefer the primary care physician to be the first address for most problems. However, half of the respondents initiated the current visit to the specialty clinic themselves. The findings also showed that a preference for the primary care physician to be the first address had an independent and statistically significant effect on the following aspects of service consumption: taking the initiative to go to a specialist, the intention to return to the primary care physician or to the specialist for continuing care, and the patient's belief that referral to a specialist was needed. The findings of the study may be of assistance to policy-makers on the national level and to sick funds in planning the role of the primary care physician, so that it corresponds, on the one hand, to the needs of the sick funds and the economic constraints in the health system, and on the other, to the preferences of the patient.

Verapamil-Associated Liver Injury

Majed Odeh, Arie Oliven

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 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.

The parasite Onchocerca volvulus is well-known in its endemic areas in South and Central America and West Africa. It is transmitted to man by simulium flies and causes systemic infection with skin, lymphatic and ophthalmic manifestations and can cause blindness (river blindness). Treatment with Ivermectin is effective but sometimes there is need for surgical intervention to prevent or treat complications. We describe an 11-year-old girl, a new immigrant from Ethiopia, who had a firm mass in her left thigh, caused by Onchocerca volvulus. It was completely excised. This is a very rare condition in Israel, which must be considered in patients coming from endemic areas.

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.

In 1994-1995, central venous lines were placed in 47 children. All except 1 were of the Broviac type, with subcutaneous tunneling via the internal or external jugular vein. Ages were between 7 days and 16 years. Indications for central venous cannulation were chemotherapy (35 cases), TPN (5), prolonged parenteral antibiotics (4), and repeated blood transfusions (3). The catheter was the source of infection in 13 children (28%), 11 of whom were immunocompromised. The commonly identified bacteria were Staphylococcus aureus (4 cases), Pseudomonas aeruginosa (4), coagulase-negative Staphylococcus (2), and various gram-negative rods (3). All cases were treated with antibiotics through the catheter. The most commonly used were oxacillin (4), ceftazidime (4), and amikacin (4). In 10, treatment succeeded without having to remove the line. In 2 others, tunnel infection developed and the catheter had to be removed. 1 child forcefully removed his catheter before treatment could be started. There were no further complications in the group treated conservatively, except for a case of superior vena cava thrombosis in a girl with recurrent infection of the tunnel. In 7 out of 13 treatment was continued and completed at home. This saved 65 days of hospitalization out of 210. We conclude that the conservative approach to treatment is feasible in most cases of infection when the source is the central venous catheter itself. However, when the tunnel is infected, conservative treatment may be ineffective. Treatment can be carried out in the home, with economy in cost and in use of hospital beds, and is preferred by patients and their parents.

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.

Bloodstream infections (BSI) are 7-fold more common in patients admitted to the intensive care unit (ICU) rather than to other hospital wards. The epidemiology of BSI in critically ill patients in Israel has not been systematically addressed. We examined the annual trends in BSI in patients in a general ICU of evolving patterns of antimicrobial resistance and associated mortality rates for the years 1994-1996. The presence of the systemic inflammatory response syndrome (SIRS) when the first positive blood cultures are taken was a prerequisite for its definition as clinically significant. The unit site, staff, practice guidelines, and type of patient were unchanged during the study period. Blood cultures were positive in 220.7-332.0 patients per 1000 ICU admissions, 18-22-fold more common than in regular ward patients. SIRS was a universal finding in these ICU patients. There was multi-drug resistance for the majority of species cultured, reaching 100% in some cases. Crude hospital mortality of ICU patients, with and without positive blood cultures, was 31-54% and 5-14%, respectively. The introduction of a new blood culture system (Bactec 9240) in 1996 was associated with a 61% increase in the rate of patients with positive blood cultures, accounted for mostly by increased isolation of coagulase-negative staphylococci. However the mortality rate for the latter decreased by 59%, suggesting the possibility of a selective increase in detection of contaminated cultures. Although highly prevalent in the study population and generally defining a patient group with high mortality risk, the specificity of SIRS-associated positive blood cultures may be species and culture-system dependent. These findings re-emphasize the need for both improved control measures for the epidemic proportions of BSI and multi-drug antimicresistance, as well as more specific indicators of the clinicaof positive blood cultures in critically ill patients.

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.

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.
