        Opinions of the National Health Insurance (NHI) Law held by primary care physicians were surveyed. A questionnaire was submitted (April-July 1997) to 930 primary care physicians employed by sick funds, including general practitioners, family physicians, pediatricians and internists. Response rate was 86%.

        They supported the main components of the NHI law. It was considered desirable "to a great" or "very great extent" to allocate funds to sick funds based on age and number of members (76%), to require them to accept all applicants (72%), to designate a uniform basket of services (65%), to allow members to transfer freely between funds (63%), and to allow sick funds to sell supplemental insurance (59%). However, only 41% were satisfied with the implementation of the law.

        Multivariate analysis showed that employment by Maccabi, Meuhedet, or Leumit sick funds had an independent effect on low satisfaction with the law as implemented, and on negative opinions about the uniform basket of services, the accepting of all applicants, and allocation of funding based on age and number of members. Those employed by the Maccabi and Meuhedet funds were in favor of allowing sick funds to sell supplemental insurance.

        The findings of the study have implications for policy-makers interested in increasing support for national health reform by physicians. It is important to examine possibilities of developing direct channels of communication between national policy-makers and physicians, as well as institutionalizing mechanisms that involve physicians directly in formulation of national policy.

        Many patients mechanically ventilated for acute respiratory failure, are treated with medication that includes a combination of cortico-steroids and non-depolarizing neuromuscular-blocking agents (NNBa). A third of them can be expected to develop delayed neuromuscular damage, which may be severe and prolonged.

        We describe a 50-year-old man who suffered from acute myeloid leukemia and was ventilated due to pneumonia. He was treated with pancuronium and cortico-steroids, and during recovery suffered quadriparesis that lasted several months.

        Typically this damage is purely motor and is accompanied by absent tendon-reflexes, sometimes with elevated creatin-kinase. Muscle biopsy usually shows deletion and degeneration of thick myosin filaments. The phenomenon is related to the duration of NNBa treatment, and probably results from an adverse synergistic effect on muscle tissue of the cortico-steroids and cortico-steroid-like NNBa given the immobilized patient.

        Awareness of this adverse effect of steroids and pancuronium, the use of passive mobilization, shortening the use of NNBa and early rehabilitation would minimize disability due to this phenomenon.

        Prader-Willi syndrome, first described in 1956, is characterized by marked hypotonia, hyperphagia, severe obesity, short stature, hypogonadism, orthopedic problems, breathing- related sleep disorders, mild to moderate mental retardation and behavioral abnormalities. The incidence of this syndrome, an expression of a genetic imprinting error in chromosome 15, is 1:10,000-1:25,000.

        We describe the medical, emotional and cognitive parameters of 34 patients in our multidisciplinary clinic for Prader-Willi syndrome. Their ages range from 5 months to 40 years and 20 are males. Excessive weight gain started at the age of 6 years, increasing to 170-370% of that predicted by height and age and short stature started after the age of 12. All males have hypogonadism; 6 patients have scoliosis. Breathing-related sleep disorders have occurred in 15.

        Children above the age of 8 years underwent neuropsychological assessment: half (9/18) have borderline intelligence while a quarter have low-normal intelligence and the remainder mild to moderate mental retardation. Behavioral and social problems are common, and become more prominent during adolescence. ADHD was diagnosed in 10/18.

        Solitary and multiple hepatic cysts are now more commonly found because of advances in imaging techniques. Most hepatic cysts are asymptomatic, but when they do cause symptoms they require surgical intervention. The advent of laparoscopy and of laparoscopic ultrasonography allow comprehensive evaluation and treatment of the cysts.

        12 patients with hepatic cysts were treated laparoscopically. 8 with single cysts underwent successful subtotal cyst resection without signs of recurrence (up to 20 years of follow-up). 4 with polycystic liver disease underwent sub-total resection of superficial cysts. Deep cysts were unroofed and drained under laparoscopic ultrasound guidance. In this group, 1 experienced recurrence of symptoms and required partial hepatectomy of the involved segment. In another, a connection between a deep cyst and bile ducts was demonstrated and cystojejunostomy was performed.

        The laparoscopic approach in the management of patients with liver cysts is effective and safe, and we recommend it as the procedure of choice for single hepatic cysts. In polycystic liver disease the procedure is much less successful.

        Constant advances and increasing experience in laparoscopic surgery renders it applicable for adrenal surgery. The wide exposure required for open adrenal surgery makes this minimally invasive procedure an attractive and advantageous alternative.

        Between 1996-1999, we performed 35 laparoscopic adrenal-ectomies in 30 patients 20-72-years old. Indications included: Conn's syndrome - 14, pheochromocytoma - 11, Cushing's syndrome - 6, nonfunctioning adenoma - 3, and metastatic sarcoma - 1.

        5 underwent bilateral laparoscopic adrenalectomy. In 3 (8.5%) the procedures were converted to open operations. Overall morbidity was 13% and there was no mortality. Mean operative time was 188 minutes, but only 130 in our last 10 cases. Mean hospital stay was 4 days and they returned to normal activity an average of 2 weeks later.

        According to our study and previous reports, laparoscopic adrenalectomy is feasible and safe and it may soon become the procedure of choice for adrenal tumors.

        Osteoarthritis results from progressive catabolic loss of cartilage proteoglycans due to imbalance between synthesis and degradation. The availability of glucosamine, an intermediate in mucopolysaccharide synthesis, can be rate-limiting for proteoglycan production in cartilage tissue culture.

        57 patients suffering from osteoarthritis of the knee were randomized into a group treated for 4 weeks with daily IV glucosamine sulfate (GS) together with 800 mg chondroitin sulfate, and a placebo group. Knee pain at rest, on movement and on palpation, as well as range of knee motion were then recorded.

        In the GS group, there was significant reduction of clinical symptoms (p<0.01), but no significant reduction in the placebo group. Physicians' assessment of tenderness and range of motion were significantly in favor of the GS group (p<0.01). In those treated with glycosamine there were no adverse reactions and no changes in laboratory blood tests.

        37 candidates for epilepsy surgery underwent the intra-carotid amytal procedure (IAP; also known as the Wada test) to determine hemispheric speech dominance and memory capacity. 31 demonstrated left hemisphere speech dominance, 2 showed evidence for bilateral language and 4 demonstrated right hemispheric language dominance.

        Our study supports a correlational relationship between handedness, lesion laterality and age of onset of seizures, as reported in earlier studies. Left-handed patients with a left hemisphere lesion whose seizures began to an early age had a strong tendency for reversed language dominance.

        Asymmetry of at least 20% in performing the memory test was taken as the cutoff score for demonstrating laterality of lesions. The asymmetry score correctly predicted laterality of lesions in all 28 patients; 6 did not have asymmetry scores and 3 were examined for language only. None of the patients who successfully passed the Wada memory test had any significant postsurgical memory deficits; 1 had transient reduction in verbal memory and 4 who did not pass the test were not operated on for this reason.

        Our results demonstrate the importance of the Wada test in determining cerebral speech dominance, in predicting post-surgical amnesia, and support its usefulness in predicting laterality of seizure focus in candidates for temporal lobectomy.

        Carbon Dioxide Gas Embolism during Laparascopic Cholecystectomy

        A case of carbon dioxide gas embolism during laparascopic cholecystetomy is presented. Prompt diagnosis and immediate treatment resulted in positive outcome. Laparascopic cholecystectomy is nowadays one of the most common operations for cholecystectomy and certainly the most frequent endoscopic surgical procedure. It is usually safe and effective. However, a number of serious complications have been reported during the procedure.

        Gas embolism is one of the complications that may occur during the initial gas insufflation or during dissection of the gall bladder. Symptoms are mainly related to the speed and the amount of gas that reaches the venous system. Early recognition and prompt treatment are required to prevent severe morbidity or even fatal outcome.

        Transesophageal echocardiography has detected many unsuspected cases of gas embolism. However, capnograph monitoring of end-tidal CO2, routinely used in everyday anesthesia, is highly reliable in alerting to the possibility of gas embolism and also in confirming its occurrence.

        In cases of suspected gas embolism close collaboration between anesthetist and surgeon is required.

        A recent further development in laparoscopic surgery is microlaparoscoopy. The technique is identical to standard 10 mm laparoscopy except for the use of small, 2 mm scopes and trocars. We used this technique in 19 patients treated from June 1998 to February 1999.

        The advantages of microlaparoscopy are: smaller incisions, less risk of damage to pelvic organs and less postoperative pain. However, the use of microlaparoscopy for operative procedures is limited to simple operations due to the limited field of vision. We urge our colleagues to consider microlaparoscopy whenever diagnostic laparoscopy is needed.

        Pancreatic lesions present a diagnostic challenge. Even modern imaging techniques are not sensitive enough in determining resectability of pancreatic tumors. A substantial proportion of patients therefore undergo unnecessary surgical exploration. We determined the impact of laparoscopy and laparoscopic ultrasound (LAPUS) examinations on surgical decision-making in 60 patients with pancreatic lesions.

        Of 48 with solid pancreatic lesions, 22 were defined by LAPUS as having nonresectable tumors, while conventional imaging studies defined only 9 of them as such. 3 of these 9 underwent successful resections of the pancreatic mass. Surgical intervention was ruled out by LAPUS in 16 patients (33.3%) but 26 had resectable lesions of whom 25 underwent surgery. 3 of this group were found to have nonresectable tumors at surgery, a false-positive rate of 6.2%. Overall sensitivity of LAPUS in our series was 88%.

        In 12 patients with cystic pancreatic lesions LAPUS contributed significantly to the preoperative decision due to clear imaging of the cystic lesion. Additional information was obtained from ultrasound guided-biopsy of the cyst wall, as well as determination of tumor-marker levels in the cystic fluid aspirate. LAPUS contributed significantly to operative management in 58%.

        Laparoscopic adrenalectomy has recently been shown to be safe and effective for a variety of benign adrenal tumors, such as aldosterone adenoma, pheochromocytoma, nonfunctioning adenoma, Cushing's adenoma and Cushing's syndrome. Recently, laparoscopic surgeons adopted an extraperitoneal approach in which a space is created by the introduction of a trocar with an inflatable balloon tip. This technique with a minimal access procedure provides direct access to the adrenal glands without interfering with intraperitoneal organs.

        Laparoscopic adrenalectomy using the extraperitoneal approach was completed in 18/20 consecutive patients. Mean operative time was 95 min (range 80-120) and median hospital stay 3 days. Blood transfusion was not required, and there were no postoperative complications.

        Resistance to antibiotics is considered the main reason for failure to eradicate Helicobacter pylori (HP). Resistance rates are different in developed and developing countries and are not known for Israel. We studied HP resistance rates in 40 patients who underwent esophagoduodenoscopy for various indications and were found to have gastric HP colonies.

         

        Sensitivity was determined by E-test, using clarythromycin, amoxycillin, clindamycin, erythromycin and metronidazole. The resistance rate for metronidazole was up to 67% but that for clindamycin was only 10%. HP was very sensitive to both macrolide antibiotics, erythromycin and clarythromycin.

        Pediatric care in the community is gradually replacing traditional care in hospitals. Despite that, research activity in the community setting is minimal due to objective difficulties. These are mainly constraints of time, office work and lack of research-supporting logistics. In the past decade, throughout the world, primary physicians interested in research have grouped together and formed research networks. The aim of such networks is to support and promote research in the community.

         

        An Israel Pediatric Research in Office-Setting network (IPROS) was established 2 years ago by the Israel Ambulatory Pediatric Association (IAPA). Today, there are over 140 pediatricians listed in IPROS, representing the heterogeneous composition of pediatricians in Israel. The network's policy is defined by a joint steering committee. The committee is composed of IAPA representatives, senior network members and Schneider Hospital senior investigators. The research subjects are diverse, and represent common practical issues.

         

        Effective intra-net communication is vital to the existence of the network, and is accomplished by 3 modalities: 1) semiannual updates by mail, 2) e-mail, using an electronic mailing list to facilitate connection between members, 3) semi-annual meetings. Research budgets are derived from public sources like the Ministry of Health and IAPA, and private sources such as pharmaceutical companies. The administration of the network is supported by Schneider Children's Medical Center, and financed by IAPA.

        Laparoscopic Donor Nephrectomy: Initial Experience

        Advanced Endoscopic Surgery Unit, Transplantation Unit and Depts. of Surgery B-C, Tel Aviv-Sourasky Medical Center and Sackler Faculty of Medicine, Tel Aviv University

         

        We present our initial experience in laparoscopic nephrectomy. 6 patients were operated for a kidney donation and 2 for treatment of a benign disease. All procedures were completed successfully, with no conversion to laparotomy or intra-operative complications. Mean operating time was 210 minutes, and in the donor kidneys the mean warm-ischemic time was 165 seconds. There were 3 postoperative complications, and mean hospitalization was 3.5 days. The transplanted kidneys are all functioning.

         

        From our initial experience, laparoscopic nephrectomy appears to be both feasible and safe. Its implementation requires a combined team with experience in donor surgery and advanced laparoscopic skills. The procedure may increase the availability of living donor kidneys, due to the smaller impact on the donor compared to conventional donor nephrectomy.

        Surgery Unit B, Wolfson Medical Center, Holon

         

        We describe our experience in 14 patients operated on for small bowel obstruction, who underwent laparoscopic adhesiolysis. In 13 (93%) the obstruction was relieved and only 1 case required conversion to open operation. Bowel activity usually resumed within 24-48 hours, and there were no remarkable intraoperative and postoperative complications. During follow-up none developed recurrent obstruction.

         

        Our experience demonstrates that laparoscopic adhesiolysis is a valid therapeutic option. Additional experience is needed to determine which types of cases are suitable for the procedure.
