Distraction osteogenesis is a well-known method for bone lengthening which stretches callus to generate new bone in the distracted area. The method was developed by Ilizarov for the lengthening of long enchondral bones. In recent years the method has also been applied to the facial bones and to the jaw.

Diarrhea is still a major cause of morbidity and mortality among children in developing countries. The Bedouin population of southern Israel is in transition from a nomadic to a settled life-style. We examined maternal knowledge and reported behavior when their children had diarrhea. Mothers defined diarrhea as the passing of 4-5 stools per day. The most frequent signs of the illness were an increased number of watery stools with changes in either color or form. The most frequent symptom that prompted mothers to seek medical aid was blood in the stool. All mothers reported increasing fluid intake in their children during diarrhea, and most reported giving herbal tea. About half of the women avoided milk products and used special for the treatment of diarrhea. A quarter of the women reported stopping or decreasing the frequency of breast feeding during diarrhea. Reported cessation of breast feeding during diarrhea was associated with changing to special foods, and failure to note the onset of diarrhea or to recognize signs of dehydration. The withdrawal of breast feeding during episodes of illness and diarrhea is related to lack of knowledge regarding diarrhea. These data indicate that even in this population, with free access to preventive and curative medical care, there should be greater efforts to educate mothers to detect diarrheal disease and to maintain breast feeding during the diarrhea.

Recurrent Chronic Multifocal Bone Infection

Dept. of Orthopedic Surgery, Carmel Medical Center, Haifa

We present a 9-year-old girl who had chronic recurrent multifocal osteomyelitis. The bones involved were: right clavicle, distal fibula (bilateral), left sacroiliac and right wrist. After 10 years of follow-up, she is asymptomatic but presents radiological evidence of lesions in the right clavicle and left sacroiliac joint. The diagnosis was made by exclusion criteria. The biopsy and results of cultures from various bones were negative 4 times. Although chronic recurrent multifocal osteomyelitis is rare, it should be considered in the differential diagnosis of acute or chronic osteomyelitis and neoplasms. Its recognition avoids unnecessary laboratory tests and antibiotic therapy.

Attention-deficit hyperactivity disorder (ADHD) has been considered a mental and behavioral disorder of childhood and adolescence. It is being increasingly recognized in adults, who may have psychiatric co-morbidity with secondary depression, or a tendency to drug and alcohol abuse. We describe a 32-year-old woman known for years as suffering from borderline personality disorder and drug dependence (including hasshish, marijuana, LSD and "exstasy'") and alcohol abuse that did not respond to treatment. Only when correctly diagnosed as ADHD and appropriately treated with the psychotropic stimulant, methylphenidate (Ritalin), was there significant improvement. She succeeded academically, which had not been possible previously, the craving for drugs diminished and a drug-free state was reached. Although administration of psychostimulants to drug abusers is controversial, as they are addictive, in cases of ADHD they have promoted drug abstinence.

Na+/H+ exchange (NHE) was measured as maximal initial velocity of pH-dependent H+ efflux from red cells into an alkaline medium containing Na+ in patients with insulin-dependent or noninsulin-dependent diabetes, with and without hypertension and in normoglycemic, essential hypertensives and normal controls (50 subjects in each subgroup). Maximal velocities of NHE were found in microalbuminuric patients in all subgroups, and NHE correlated with the rate of microalbuminuria (r=0.61, p=0.02). Daily insulin requirements were greater in those with elevated NHE (84±8 vs 42±4 U/day). There was no correlation between NHE and levels of plasma glucose, HbA1 and plasma aldosterone and lipid profile and PRA. NHE was correlated with plasma prolactin (r=0.51, p=0.02) and PTH r=0.24, p=0.05). In uremic patients, NHE was inversively correlated with creatinine clearance (r=-0.48, p=0.03). Since calphostin C, a selective inhibitor of protein kinase C, lowered increased NHE in vitro, the protein kinase C-dependent pathway of the exchanger regulation was concluded to be responsible for NHE activation in diabetes mellitus and essential hypertension.

Use of Student Feedback by Pre-Clinical and Clinical Course Directors

Ruth Abramowitz, Netta Notzer

Medical Education Unit, Sackler Faculty of Medicine, Tel Aviv University

We examined the conceptual and instrumental uses of student feedback on teaching by 2 preclinical and clinical course directors with authority to change structure and content of the courses, assess suitability of instructors and to change methods of student feedback questionnaires have been collected systematically for over 2 decades. A report based on this feedback is sent to course directors, the dean, his assistants and the head of the curriculum committee. Course directors from both groups made broad use of the feedback but made greater use of the report than preclinical course directors. Students had greater regard for individual teaching by clinical course directors than by preclinical course coordinators. No relationship was found between the degree of use of feedback by members of either group and their level of teaching. We conclude that senior faculty use student feedback in their decisions regarding the structure and teaching methods of their courses and are not influenced by individual assessments, positive or negative, by their students.

Division of Medicine, Hadassah University Hospital, Jerusalem

A 20-year-old asthmatic woman who ingested 300 mg of salbutamol (Albuterol) and 30 g of paracetamol is presented. She had sinus tachycardia up to 160/min, hypotension (80/50 mmHg), tremor, hypokalemia (2.1 mEq/l) and hyperglycemia (12.1 mEq/l). Treatment was by gastric lavage, fluids, potassium and N-acetylcysteine. Symptoms resolved in 24 hours.

Superficial Dorsal Penile Vein Thrombosis (Mondor's Disease)

Ran Katz, Arye Blachar

Superficial venous thrombosis of the chest wall was first described by Mondor in 1939. Braun-Falco reported in 1955 superficial penile vein involvement in diffuse thrombophlebitis of the abdominal wall and in 1958 Helm and Hodge first described isolated superficial dorsal penile vein thrombosis. Since then, fewer than 50 cases have been reported. The clinical presentation is usually redness and swelling of the dorsum of the penis, accompanied by a palpable, tender thrombotic vein. This acute and painful disease frightens the patient, who is concerned about his fertility and sexual function. The main cause of this disease is frequent sexual intercourse. Diagnosis is based upon anamnesis, physical examination and penile sonography with color Doppler imaging. It is usually a benign disease which resolves quickly under appropriate medical therapy. We present a man who was admitted for this condition and was successfully treated.

A random sample of 32,166 soldiers were interviewed (on their day of discharge from the Israeli Defence Forces, between 1980-1995) with regard to smoking habits. Among men, prevalence of current smoking was 46.8%, and among women 32.9%. Over the study period, prevalence in men decreased 27%. Among women, prevalence decreased from 1981 to 1991, but since then it has steadily increased. Among men, mean number of cigarettes smoked decreased from 21.6 in 1989 to 16.6 in 1995. Among women cigarettes smoked decreased from a mean of 14.3 in 1989 to 13.1 in 1995. 65.9% of the men and 49.3% of the women had started smoking by the age of 18. Among men the age distribution of smoking changed hardly at all over the years of the study. However, the proportion of women who began to smoke in the youngest age bracket (15 years of younger) doubled over the course of the study.

2 patients aged 12 and 19, respectively, sustained open fractures of the wrists due to dog bites. Both were bitten on a wrist by Rotweiller dogs, but with different magnitudes of injury to bone and soft tissue. Treatment, clinical course and recovery are described, together with recommendations for dealing with open fractures due to animal bites. In the presence of considerable injury to soft tissue and bone, and of exposure to canine oral flora, open fractures due to dog bites should be dealt with as high grade open fractures.

Transitional cell carcinoma (TCC) with trophoblastic differentiation (TD) is a newly recognized variant of urothelial cancer which produces placental proteins, predominantly beta-human chorionic gonadotropin (HCG). It has a poor prognosis. About 210 cases were described, mostly from North America, Europe and Japan. This is the first report of TCC TD in a resident of Israel's upper Galilee. A 69-year-old man whose urinary papillary bladder tumor was established cystoscopically, refused treatment and stopped follow-up. 3.5 years after his last visit, he returned and cytologic examination revealed malignant urothelial cells, while intravenous pyelography disclosed a urinary bladder defect. Cystoscopy showed numerous papillary masses dispersed over the bladder mucosa, which were resected transurethrally. Histopathologic examination revealed TCC grade III, stage A. Tumor cells were immunopositive for beta-HCG and human placental lactogen. 4 transurethral resections of large masses were performed within 2 months. Pulmonary metastases developed and the patient died 4 years after the detection of the urinary bladder tumor.

Biological Test for Menopausal Osteoporosis

Osteoporosis has become a major public health problem in many western countries in which about 25% of women by the age of 65 will have had osteopenic fractures. The most important contributing factor to this condition is loss of gonadal function. This progressive disease, characterized by reduction in bone mass, may be prevented by estrogen replacement therapy. While there are several methods of diagnosing the disease when already established, there is no method that can identify women at high risk of developing osteoporosis. We have developed a biological test in which the serum of postmenopausal women is added to rat osteoprogenitor cell culture and its influence on proliferation, differentiation and mineralization of bone cells is determined. The serum of 20 menopausal women was examined by the biological test and the results compared to the findings of dual photon absorptiometry. This showed that rapid bone-losers had a significantly lower mineralization index as compared to nonosteopenic women (p<0.0001). The proliferation index (cell count) and alkaline phosphatase activity did not show significant differences between osteopenic and nonosteopenic groups. This preliminary study showed that a test based on serum reacting with a culture of bone cells to induce mineralization may be of value in the diagnosis of osteoporosis.

Between 1993-1996, 200 pediatric flexible bronchoscopies were performed. Indications were: chronic cough (158 children), persistent pulmonary infiltrates (89), recurrent stridor (28), suspected tracheobronchial foreign body (20), suspected tuberculosis (17) and hemoptysis (3). Some children had more than 1 indication. 124 patients were boys (mean 4.18+2.86 years; range 1 month-15 years) and 76 were girls (mean 4.39+2.7 years; range 4 months-15 years). The procedure included direct vision recorded by video-camera and broncho-alveolar lavage; the lavage fluid was sent for culture, Gram and Ziehl-Nielsen stains and for cytology. There were a few minor side effects: mild stridor which resolved within a few hours (10 children) and transient fever (3). This simple, flexible instrument was effective and helpful in the diagnosis and treatment of children with respiratory symptoms in a secondary hospital facility.

We report a 59-year-old woman with acute fungal endocarditis of a prosthetic valve caused by the endogenic organism, Trichosporon beigelli. This slowly developing disease mainly effects drug addicts who use intravenous narcotics. In nonaddicts it is rare, with mortality as high as 50%. There are only sporadic reports of T. beigelli as a complication long after open heart surgery. The ongoing infection is undetected for even several years after the primary infection, due to its prolonged latent phase. We present the difficulties of diagnosis, and of treating the disease with a combination of surgery and of long-term chemotherapy.

CT-guided core needle biopsy of abdominal, pelvic and retroperitoneal masses is accurate and safe and can be performed on an outpatient basis. Between 1987 and 1995, 809 patients (age range 1-87 years) underwent 851 biopsies (minimal lesion diameter 1 cm). Cutting needles were always used, facilitating both cytological and histological diagnosis while minimizing risk of complications. A positive result (malignant, inflammatory or infectious) was obtained in 69% of the 809 and a negative result (normal tissue) in 17.4%, while in 13.6%, material for diagnosis was insufficient. Biopsy was repeated in 42 of them in whom radiological or clinical suspicion of malignancy was high. In 24 (60%) a positive result was obtained after the second biopsy.

Significant complications occurred in 7 (0.8%). 1 hemo-rrhaged following liver biopsy and required blood transfusion. Pancreatitis occurred in 6 (2.6%) following pancreatic biopsy. An intra-abdominal fluid collection in 1 necessitated percutaneous drainage. There was no mortality following the procedure and no documented case of needle-tract seeding of tumor. All outpatients were discharged within 3 hours of completion of the biopsy, without ill effects.
