Background: The frequent coexistence of two or more sexually transmitted diseases in one patient has been reported in non-dermatological literature, mostly in languages other than English. Identification of Ureaplasma urealyticum, Chlamydia trachomatis and Mycoplasma hominis in men with other STDs is important, since these bacteria have been implicated in a variety of diseases such as non-gonococcal urethritis, premature rupture of fetal membranes, and infertility in female sexual partners of these patients.

Objective: To assess the frequency of concomitant STD, particularly urethral colonization of U. urealyticum, C. trachomatis and M. hominis, in men consulting for suspected STD-related symptoms.

Methods: All patients attending our dermatology clinic for STD-related symptoms during a 12 month period in 1996–97 underwent systematic clinical and laboratory screening for syphilis, gonorrhea, NGU, prostatitis, genital herpes simplex infection, Condyloma acuminatum, urethral carriage of U. urealyticum, C. trachomatis and M. hominis, as well as serological screening for HIV, and hepatitis B and C infections.

Results: A total of 169 men with STD-related symptoms were enrolled in the study. The following clinical diagnoses were established: NGU in 109 men, C. acuminatum in 40, genital herpes simplex in 10, prostatitis in 7, latent syphilis in 6, primary syphilis in 1, and Behcet’s disease in 1. No clinical evidence of STD was found in 13 patients. Of the 169 patients, 39 (23%) had two or more concomitant STDs, of whom 27 (69%) had C. acuminatum associated with one or more of the urethral pathogens. A positive U. urealyticum culture was found in 67.5% (27/40) of the men with C. acuminatum as compared to 42% (40/96) among the patients with NGU who did not have C. acuminatum (P=0.004, X2 test). Conversely, the prevalence of C. acuminatum among patients positive for U. urealyticum was significantly higher than the prevalence among those who were negative – 27/75 (36%) vs. 13/94 (14%), P<0.0009, X2 test. About half of the U. urealyticum-positive patients with C. acuminatum had no clinical signs or symptoms of urethritis.

Conclusion: Our findings suggest that patients with C. acuminatum should be assessed for U. urealyticum carriage and, when identified, their sexual contacts should be actively sought and treated.

Background: Carbohydrate malabsorption of lactose, fructose and sorbitol has already been described in normal volunteers and in patients with functional bowel complaints including irritable bowel syndrome. Elimination of the offending sugar(s) should result in clinical improvement.

Objective: To examine the importance of carbohydrate malabsorption in outpatients previously diagnosed as having functional bowel disorders, and to estimate the degree of clinical improvement following dietary restriction of the malabsorbed sugar(s).

Methods: A cohort of 239 patients defined as functional bowel complaints was divided into a group of 94 patients who met the Rome criteria for irritable bowel syndrome and a second group of 145 patients who did not fulfill these criteria and were defined as functional complaints. Lactose (18 g), fructose (25 g) and a mixture of fructose (25 g) plus sorbitol (5 g) solutions were administered at weekly intervals. End-expiratory hydrogen and methane breath samples were collected at 30 minute intervals for 4 hours. Incomplete absorption was defined as an increment in breath hydrogen of at least 20 ppm, or its equivalent in methane of at least 5 ppm. All patients received a diet without the offending sugar(s) for one month.

Results: Only 7% of patients with IBS and 8% of patients with FC absorbed all three sugars normally. The frequency of isolated lactose malabsorption was 16% and 12% respectively. The association of lactose and fructose-sorbitol malabsorption occurred in 61% of both patient groups. The frequency of sugar malabsorption among patients in both groups was 78% for lactose malabsorption (IBS 82%, FC 75%), 44% for fructose malabsorption and 73% for fructose-sorbitol malabsorption (IBS 70%, FC 75%). A marked improvement occurred in 56% of IBS and 60% of FC patients following dietary restriction. The number of symptoms decreased significantly in both groups (P<0.01) and correlated with the improvement index (IBS P<0.05, FC P<0.025).

Conclusions: Combined sugar malabsorption patterns are common in functional bowel disorders and may contribute to symptomatology in most patients. Dietary restriction of the offending sugar(s) should be implemented before the institution of drug therapy.

Background: About one-third of patients with severe ulcerative colitis do not respond to conventional therapy and require urgent colectomy. It was recently shown that cyclosporin is effective in some of these patients.

Objectives: To review the current experience of six hospitals in central Israel that used cyc-losporin in patients with severe ulcerative colitis.

Methods: The files of all 32 patients treated with cyclosporin for corticosteroid-resistant ulcerative colitis were reviewed. Activity of disease was measured by a clinical activity, index colonoscopy and laboratory tests.

Results: The average duration of treatment with intravenous cyclosporin was 12.7 days (range 9–28) after which the disease activity index dropped from an average of 14.22 to 4.74. The mean time for response was 7.5 days (4–14). Twelve patients (40%) required surgery within 6 months and another 6 patients (18.8%) were operated on after more than 6 months. Twelve patients (37%) maintained remission for at least 6 months and did not require surgery. In one patient treatment was stopped because of non-compliance and one was lost to follow-up. There were numerous side effects, but in only one case with neurotoxicity was treatment withdrawn.

Conclusions: Cyclosporin is a relatively safe and effective treatment for severe ulcerative colitis. It induced long-term remission in 37% of the patients, and in those who required surgery the treatment resulted in an improved clinical condition before the operation.

Background: Many medications used for children have not undergone evaluation to assure acceptable standards for optimal dose, safety and efficacy. As a result, the majority of children admitted to hospital wards receive medications outside the terms of their license (off-label) or medications that are not specifically licensed for use in children (unlicensed). The extent of unlicensed and off-label medication use in ambulatory children is unknown.

Objective: To determine the extent of unlicensed and off-label medication use in a general pediatrics ambulatory hospital unit in Israel.

Patients and Methods: We conducted a retrospective analysis of the medical records of 132 outpatient children treated in the General Pediatrics Ambulatory Unit of the Soroka Medical Center, Beer Sheva, in November–December 1998.

Results: The children’s ages ranged from 1 month to 18 years (mean ± SD 50±58 months). Of the 222 prescriptions given to these children, one-third were unlicensed (8%) or unlabeled (26%). Different dose and age were the most common categories of off-label medication use. All 18 cases of unlicensed use were due to modifica-tion of licensed drugs (tablets were crushed to prepare suspensions). Altogether, 42% of children received medicines that were off-label and/or unlicensed.

Conclusions: More off-label than unlicensed medications were used. Further investigations are required to establish the extent of unproved drug use in both hospitalized and ambulatory pediatric patients in Israel. Recommendations recently issued by the Ministry of Health’s National Council for Child Health and Pediatrics constitute a first step in the Israeli contribution to the international effort demanding testing of medications for children.

Background: Achondroplasia is the most frequent form of disproportionate short stature, characterized by rhizomelic shortening of the limbs. This disorder is inherited as an autosomal dominant trait, although most of the cases are sporadic, a result of a de novo mutation. A recurrent glycine to arginine mutation at codon 380 (G380R) in the transmembrane domain of the fibroblast growth factor receptor 3 gene was found to cause achondroplasia among different populations. This is most uncommon in other autosomal dominant genetic diseases.

Objectives: To determine whether this mutation is also common among Jewish patients from diverse ethnic groups and among the Arab population in Israel.

Methods: We examined the G380R mutation (G>A and G>C transition) and the mutation G375C (G>T transition at codon 375) in 31 sporadic patients and in one family diagnosed clinically to have achondroplasia.

Results: We found the G>A transition at codon 380 in 30 of our patients and the G>C transition in one patient. We were not able to detect any of the three mutations in two patients with an atypical form of achondroplasia.

Conclusions: Our results further support the unusual observation that nucleotide 1138 of the FGFR3 gene is the most mutable nucleotide discovered to date across different populations.

Background: A previous study on Hodgkin's lymphoma in southern Israel found that Bedouin patients had an increased rate of Epstein-Barr virus expression in their tumor cells.

Objectives: To determine the influence of the patients' communities on the pattern of disease in HL.

Methods: We compared the clinical features, demographic data, stage at diagnosis, treatment modality and outcome, as well as laboratory findings, in four community-based subgroups. These groups comprised kibbutz residents (n=11), Bedouin (n=19), new immigrants from the former USSR (n=22), and town-dwellers (n=82).

Results: The Bedouin patients differed significantly from the new immigrants and town-dwellers, particularly regarding the rate of EBV sequences in the tumor tissues, and a poorer response to treatment. The kibbutz patients did not differ significantly from the other populations regarding most of the parameters studied, but showed an intermediate expression of EBV antigens compared to Bedouin patients and the rest of the cohort.

Conclusions: This study indicates that HL may behave differently in different population groups in a given geographic area. Notably, the Bedouin patients showed markedly different clinical and biological patterns of this malignancy.

Background: Childhood poisoning continues to challenge the diagnostic and treatment skills of the pediatrician. Generally, childhood poisoning can be attributed to suboptimal parental supervision and accessibility of products with poisoning potential.

Objective: To evaluate the pattern of acute poisoning in children with relation to different age groupings.

Methods: Pediatric patients hospitalized for acute poisoning at the Soroka Medical Center over a 5 year period (1994-98) were evaluated retrospectively. Special attention was given to poisoning in relation to age groupings.

Results: During the years 1994-98 a total of 1,143 children were admitted for acute poisoning to the Soroka Medical Center. The majority of cases occurred in children aged 2-5 and 14-18 years. Males under 14 had a higher frequency of poisoning, the poisoning usually being unintentional, whereas poisoning in females occurred mostly in the 14-18 age group and was intentional. Drugs were the most common agent of poisoning in infants (0-1 year), in older children (10-13 years), and in adolescents (14-18 years), while in children aged 2-5 and 6-9 years either cleaning products or drugs were the usual agents of poisoning. Most poisonings in children aged 2-13 occurred between 4 and 8 p.m., and for most adolescent patients (14-18 years old) between 4 p.m. and midnight. Poisoning in children aged 2-13 were usually due to accessible home products, and to medicinal errors such as overdose and improper drug administration.

Conclusions: This study defines the characteristic pattern of pediatric poisoning with respect to different age groups and gender. Unintentional childhood poisoning predominated in males and occurred mostly because of accessible home products and suboptimal parental supervision during critical hours of the day. Most adolescent poisoning occurred in females and was intentional. Parental education and intensified child supervision are indicated measures of prevention for unintentional poisoning.

Background: Over the last 5 years Israel has implemented a nationwide health insurance plan covering the entire population of the country. We have developed a clinical information system based on electronic-chip health care medical smart cards. Health care cards are used in several European countries and chip smart cards have been successful in many sectors. Our project involves the community use of the MSC, thereby enabling health care professionals to skillfully employ card systems in the health care sector. This system can easily arrange electronic medical charts in clinics, facilitating the confidential sharing of personal health databases among health professionals.

Objectives: To develop an MSC applicable for daily use in the community and hospital system.

Results and Conclusions: The MSC project, currently underway in Israel and the USA, will aid in determining the costs, benefits and feasibility of the MSC. Successful implementation of the MSC in chosen clinics will promote a nationwide willingness to adopt this promising technology.

Background: General pediatricians in Israel are actively involved in the initial evaluation, resuscitation and management of traumatized children. However, pediatric trauma care is not a part of pediatric specialty training in Israel, and the few Advanced Trauma Life SupportR courses per year are insufficient for most pediatricians working in accident and emergency care.

Objective: To examine the value of the course in relation to the limited resources available for such training.

Methods: A telephone survey of 115 pediatricians who had taken the course between 1990 and 1994 was conducted. The responding physicians (67%) were asked to complete a specially designed questionnaire on life-saving procedures that were taught in the course. In addition, they were asked to subjectively assess the practical utility of the course.

Results: Forty-three (56%) pediatricians reported that they routinely treated both adult and pediatric trauma cases. Of these, 81% performed 27 life-saving ATLSR procedures. Pediatric trauma was treated by only 22 (28%), of whom 72.3% performed 18 life-saving ATLSR procedures. These pediatricians ranked the courses as being "very high" to "high" in impact.

Conclusions: These figures indicate that an ATLSR course designed specifically for pediatricians can markedly improve pediatric trauma care. To ensure standard education and patient care, such a course should be developed and made a mandatory component of residency training. Further studies to examine the objective impact of the courses on pediatric trauma care should be carried out.

Background: In simultaneous pancreas-kidney transplantation, with both organs coming from the same donor, the addition of a pancreas to the kidney transplant does not jeopardize the kidney allograft outcome despite higher postoperative SPK morbidity. Pancreas allograft outcome has recently improved due to better organ selection and more accurate surgical techniques.

Objective: To demonstrate the positive impact of SPK on kidney allograft outcome versus kidney transplantation alone in insulin-dependent diabetes mellitus patients with end-stage renal failure.

Methods: We performed 39 consecutive SPKs in 14 female and 25 male IDDM patients with renal failure after an average waiting time of 9 months. Multi-organ donor age was 30 years (range 12-53). The kidneys were transplanted in the left retroperitoneal iliac fossa following completion of the pancreas transplantation; kidney cold ischemia time was 16±4 hours. Induction anti-rejection therapy was achieved with polyclonal antithymocytic globulin and methylprednisolone, and maintenance immunosuppression by triple drug therapy (prednisone, cyclosporine or tacrolimus, and azathioprine or mycophenolate mofetil). Infection and rejection were closely monitored.

Results: All kidney allografts produced immediate urinary output following SPK. Two renal grafts had mild function impairment due to acute tubular damage but recovered after a short delay. Three patients died from myocardial infarction, cerebrovascular event and abdominal sepsis on days 1, 32 and 45 respectively (1 year patient survival 92%). An additional kidney allograft was lost due to a renal artery pseudo-aneurysm requiring nephrectomy on day 26. Nineteen patients (49%) had an early rejection of the kidney that was resistant to pulse-steroid therapy in 6. No kidney graft was lost due to rejection. Patients with acute kidney-pancreas rejection episodes suffered from severe infection, which was the main cause of morbidity with a 55% re-admission rate. Complications of the pancreas allograft included graft pancreatitis and sepsis, leading to a poor kidney outcome with sub-optimal kidney function at 1 year. Kidney graft survival at one year was 89% or 95% after censoring the data for patients who died with functioning grafts.

Conclusions: Eligible IDDM patients with advanced diabetic nephropathy should choose SPK over kidney transplantation alone from either a cadaver or a living source.
