Learning methods chosen by residents in family medicine during their residency and the correlation between them and achievement in the written specialty exams (Stage 1) were investigated. The learning patterns studied were: structured learning (certification course, study with a tutor, staff meetings, conferences) and self-learning (textbooks, journals, the Hebrew publication "Update," and audio tapes). Of 184 residents who took the examination in 1994-5, 104 responded to a questionnaire as to preferences for the various learning aids and satisfaction with their use. There was no correlation between use of a given learning method and success in the examination. Significantly more candidates preferred self-learning, especially among those who were successful, but also among some who failed the examination. There was no direct connection between the examination and the high level requirements of the residency program, for which up-to-date, integrated knowledge based on self-learning is needed.

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 craniotomy, the patient's cooperation is needed during procedures in which continuous neurological examination and mapping of crucial regions close to the area to be resected area are required. We report our experience in 9 patients who underwent such procedures under intravenous propofol as the main sedating agent. This short-acting hypnotic was administered prior to and during the painful stages of the procedure. Patients were fully asleep when the skull was opened and the dural flap raised or excised. During the rest of the operation patients were lightly sedated but remained responsive and cooperative. This enabled precise intra-operative mapping of the brain and surgery-related neurological deficits were avoided. Respiratory depression or hemodynamic compromise were not encountered. All patients were comfortable during the operation and there were no additional neurological deficits after operation. We believe that propofol should be the main sedating agent used for these procedures.

There are few reports contrasting the clinical characteristics of Crohn's disease in different age groups. We therefore compared retrospectively children and adults with Crohn's disease. 23 children (mean age: 12.8±2.5 years) and 66 adults (mean age: 27.0±4.0 years) were studied. Presenting symptoms of abdominal pain and diarrhea were significantly more common in adults, while in children anorexia and weight loss were more frequent. Children tended to present with extra-gastrointestinal tract symptoms as well, mainly anemia and joint involvement. Common symptoms during active disease did not differ between groups, except that weight loss, evident in all children, was found in only 70% of adults. Anemia was present during active disease in all pediatric cases but in only 62% of adults. There were no significant differences between groups regarding disease location, gastrointestinal complications and extra-intestinal manifestations. We conclude that in children Crohn's disease may differ significantly, mainly presenting with nonclassical symptoms, such as anemia and joint involvement. The primary care physician should be aware of these differences.

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.

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.

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.

2 children with pyogenic liver abscesses were hospitalized during the past 2 years. A 6-year-old boy had high fever and hepatomegaly, and a large liver abscess was found in the right hepatic lobe. Streptococcus milleri was isolated from the pus. Treatment with a combination of prolonged drainage of the abscess and antibiotic therapy was successful. A 4-month-old girl who had prolonged fever was found to have osteomyelitis of 3 thoracic vertebrae and 2 liver abscesses in the right lobe. She was treated successfully with broad spectrum antibiotics. Additional workup revealed that she had chronic granulomatous disease.

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.

Family Medicine Dept., Ben-Gurion University of the Negev, Beer Sheba

The use of sunscreen in the Negev population was assessed. The study population included 1458 subjects, mean age 35.5‏±14.2 years, half born in Israel and 25% in East Europe. Two-thirds were exposed to the sun 1-2 hours a day and 13% 4 hours a day or more. Only about 15% used sunscreen while shopping, 69% used it at the beach, and less than half applied it to children being sent to school. Sunscreen use was greater in women (p<0.000001), especially those with sensitive skin (p<0.0001) and red hair (p<0.0001). No significant association was found with age, education or country of birth.

Ulnar nerve neuropathy of the elbow is a recognized complication of surgery involving general anesthesia. In 13 patients, aged 21-76 years, ulnar nerve palsy developed at various times and of varying degrees of severity during the postoperative period. Diagnosis was based on clinical and electrophysiological findings. 3 patients had subclinical entrapment of the ulnar nerve. All were treated conservatively by rest, splinting and physical therapy: 10 improved slowly with time and 3 were operated on, but only 1 recovered fully. Preventive measures, such as proper positioning on the operative table, use of elbow pads, avoiding adduction of the arm, pronation of the forearm and prolonged elbow flexion, may reduce the incidence of ulnar nerve palsy. Unfortunately, treatment of established lesions has yielded mixed results.

The potential parapharyngeal space contains the great vessels of the neck, cranial nerves IX-XII, the sympathetic chain and lymph nodes. Surgical access is difficult and the infrequency of tumors in it make surgery of this part of the head and neck a challenge. 8 women and 2 men (mean age 54.7, range 31-70 years) with tumors of the parapharyngeal space operated on during the past 6 years are presented. The most common surgical approach was the cervical submandibular, used in 6 of our patients with relative ease and minimal complications. Tumors of deep lobe parotid origin should be operated through a transparotid approach. Large benign or malignant tumors have a better prognosis when the transcervical transmandibular approach is used, providing wider access.

Benign cecal ulcer is a rare lesion, usually diagnosed during operation for suspected acute appendicitis or peritonitis of unknown origin. In the past, right hemicolectomy was recommended as the treatment of choice because of the difficulty in differentiating malignant lesions from benign cecal ulcers. However, in recent reports a more conservative approach has been suggested, consisting of selective colectomy followed by frozen section biopsy. This approach is aimed at preventing unnecessary excision of the colon and conserving the ileocecal valve. We present a 47-year-old woman operated for right lower quadrant peritonitis, believed to be due to acute appendicitis. On exploration, a biopsy-proven benign cecal ulcer was found and resected.
