        Non-Penetrating Deep Sclerectomy without Collagen Implantfor Glaucoma


        Ben Zion Silverstone, Isaac Aizenman, Carmit Landau, Yaacov Rozenman


        Ophthalmology Dept., Shaare Zedek Medical Center, Jerusalem


        Deep sclerectomy (DS) can be used in glaucoma with increased intraocular pressure when medical treatment fails. It involves removing part of the ocular drainage apparatus. Resistance to intraocular fluid drainage is decreased, improving drainage and decreasing intraocular pressure. By avoiding anterior chamber penetration, DS diminishes frequency of the complications of filtering surgery.

        24 eyes of 23 patients underwent DS for primary or secondary open angle glaucoma with elevated intraocular pressure not controlled medically. It included preparation of a 4.0 x 4.0 mm limbal-based external scleral flap, dissecting and removing most of an internal scleral flap (leaving it 1 mm smaller than the external flap), unroofing Schlemm's canal and removing fine endothelial tissue lining its inner walls. The external scleral flap was then repositioned and sutured. Collagen implants were not used. In some cases DS was combined with extracapsular cataract extraction and intra-ocular lens implantation.

        Mean intraocular pressure decreased from 24.8‏3.9 mmHg initially to 12.8‏4.4 mmHg 6 months after operation (p<0.0001). There was no difference in postoperative intra-ocular pressure between DS as a single procedure or as part of a combined operation. Comations were mild and of short duration.

        If long-term follow-up shows that lowered intraocular pressures are maintained, DS should be a surgical option in earlier stages of glaucoma.

        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.

        The rich blood supply of the stomach protects it from ischemia and necrosis. Acute gastric ischemia, an emergency with high mortality, is rare. Atherosclerosis is the leading cause of acute ischemia, and the lesser curvature of the stomach is more vulnerable due to its relatively lesser blood supply. Reduction in gastric blood supply usually presents as chronic disease characterized by gastritis, gastric ulcer, or gastroparesis.

        Gastroscopy can identify lesions of the gastric mucosa, and angiography demonstrates occluded vessels. Treatment of acute gastric ischemia is surgical, with total gastrectomy preferred over partial resection.

        Age over 80 years is generally considered an independent risk factor in elective surgery for abdominal aortic aneurysm (AAA). As the general population increases in age, more elderly are likely to be candidates for such surgery.

        We studied prospectively 100 consecutive patients undergoing elective AAA surgery between 1992-1995. All were operated on by the same team of anesthetists and surgeons and all were transferred to the general ICU for at least the first 24 hours. 16 were above the age of 80 (Group I) and 84 below (Group II).

        We recorded preoperative factors (demographics, medical history, risk factor indices, EKG findings, as well as left ventricular ejection fraction (LVEF) and stress imaging when indicated); intraoperative factors (duration of surgery, size of aneurysm, complications and units of blood transfused); postoperative factors (length of ICU stay, duration of ventilation, APACHE II [Acute Physiological and Chronic Health Evaluation] and TISS [Therapeutic Intervention Scoring System] scores; complications in the ICU, need for readmission to the ICU, and mortality).

        In Group I LVEF was greater (p=0.03) and aneurysm size significantly larger (p=0.036), but there were no other significant differences between the 2 groups with regard to pre- and intraoperative data. Group I patients were not ventilated as long (p=0.038), but there were no significant differences in outcome factors. Mortality for the whole group was 5% and was not significantly different in the 2 groups (1/16 in Group I and 4/84 in Group II).

        We conclude that there is no excess morbidity or mortality in octogenarians undergoing AAA surgery. However risk of the aneurysms rupturing is significantly greater since they are larger. We suggest that age not be considered the sole criterion for aneurysm repair, or at least not in selected patients with normal LVEF.

        Carbamazepine (C) can cause a characteristic hypersensitivity reaction (CHS}. This multisystem reaction typically presents as fever, mucocutaneous eruption and lymphadenopathy. The syndrome usually develops between 1 week and 3 months after starting therapy, with involvement of the liver, lung, kidney and inappropriate secretion of ADH. The incidence is less than 0.001% in those treated with C and it is diagnosed clinically. With onset of CHS, the drug must be stopped and if there is no improvement, cortico-steroids should be started. When the diagnosis is in doubt, the patch test, lymphocyte transformation test, macrophage migration inhibitor factor, and other tests can be helpful.

        The pathogenesis is not known. Similar syndromes have been described with phenytoin and phenobarbital. There is clinical and in-vitro evidence of cross reactions between C and phenytoin. It is not known whether the CHS syndrome should be considered a premalignant state, with increased risk for the development of malignant lymphoma.

        Psychiatry Chronic Dept., Eitanim Mental Health Center, Jerusalem


        There are 2 stages of alopecia, anagen and telogen effluvium, both of which may be associated with medication- related alopecia. We describe massive hair loss in a 51-year-old woman during treatment with Seroxat (paroxetine), which remitted after it was discontinued. Pathological mechanisms of drug-associated alopecia are complex and have yet to be fully elucidated.

        The Gift of Breastfeeding 

        Dorit Nitzan Kaluski, Alex Leventhal


        Dept. of Nutrition, Public Health Services, Israel Ministry of Health, Jerusalem


        Breast milk is the optimal food for infant growth and development, the prevention of infectious diseases and mother- child bonding. From the economic perspective, breastfeeding is cost-effective both for the family and society as a whole. The Israeli Ministry of Health encourages breastfeeding as the exclusive source of nutrition for infants in the first 4-6 months of life, with gradual addition of complementary foods thereafter. The promotion of breastfeeding in Israel requires comprehensive national activity with involvement of all the stakeholders. This includes implementation of the International Code of Marketing of Breast Milk Substitutes and joining the international "Baby Friendly Hospitals" project. Knowledge of breastfeeding should be spread, health professionals should be encouraged to become agents of change, support by breast counselors should be encouraged, post-delivery vacations from work should be prolonged and empowerment of women implemented.

        Etoposide and cisplatin (EP) has been the standard therapy for non-small cell lung cancer (NSCLC) at many cancer centers for over a decade. We analyzed our experience with EP in NSCLC to provide a baseline for comparison with new drugs. From 1986 through 1994, 46 of our patients with NSCLC received EP as first-line chemotherapy. Radiation therapy was administered to 25 of them, including 20 who received it immediately before or concomitantly with chemotherapy. Toxicity was mild and included only 1 episode of neutropenic fever and 1 case of reversible renal failure.

        Overall response was 22%. In 3, response was complete (pathologically documented in 2 of them) and in 7 partial. Median survival in locally advanced (stage III) and metastatic disease (stage IV and recurrent) were 12 months and 7 months, respectively. 2 patients are alive and free of disease more than 6 years after diagnosis.

        Our results are consistent with other published studies of EP in NSCLC. EP provides modest benefit in locally advanced NSCLC, with minimal toxicity.

        Depts. of Obstetrics and Gynecology and of Pathology, Misgav Ladach Hospital, Jerusalem


        The increased rate of cesarean sections in recent decades has brought with it an increase in the frequency of placenta accreta. There are direct correlations between previous cesarean deliveries and also maternal age, with the risk of placenta accreta. There is also a direct correlation between placenta accreta and placenta previa.

        The risk of placenta accreta in women who have had placenta previa is 2% for those younger than 35 years and with no history of uterine surgery. The risk increases to 39% for those over 35 who have had 2 or more cesarean sections.

        We present 3 cases of placenta accreta admitted in 15 months, all of whom had a history of cesarean sections. The frequency of placenta accreta in our hospital is 1:1,579 deliveries, in line with the 1:1,420 in the literature. We consider hysterectomy the treatment of choice for this serious complication. When performing a cesarean in cases of placenta previa with a history of cesarean sections, the possibility of placenta accreta should be considered.

        The population of the Negev consists mainly of Jews and Bedouin, who have very different life styles. Patients of both ethnic groups use our emergency department exclusively, providing a unique opportunity to study comparative patient habits.

        In gathering and processing the information we used Data Mining technology, which allows search for unique patterns in large data bases. We examined demographic data on some 64,000 emergency department visits during 1997-8, mostly medical and surgical cases, but not trauma cases. Many more were by Bedouin than Jews, and between the ages of 25 and 44, more by women than men. There were changes in trends in comparison with an arrival survey conducted some 11 years before.

        Flying may expose passengers to hypoxic conditions, which may induce hypoxemia, particularly in those with chronic heart and/or lung disease. Onset of dyspnea, wheezing, chest pain, cyanosis and right heart failure can lead to urgent need for oxygen during flight. The hypoxia inhalation test (HIT) provides a safe and simple means of identifying those who may develop hypoxemia during flight.

        We report our experience with 48 self-reporting patients who underwent HIT prior to pre-planned air travel. They inhaled for 15-minute periods a reduced oxygen concentration (F1O2 15%) under normobaric conditions, during which O2 saturation was monitored by pulse oximeter; electrocardiogram, blood pressure and symptoms were also monitored. O2 saturation of 85% (PaO2 50 mm Hg) was considered a positive test. In the 8 cases (17%) with a positive test, 5 had chronic obstructive pulmonary disease and 3 had cardiovascular and/or combined heart-lung disease.

        We calculated predicted O2 partial pressure in altitude (PaO2 ALT) and compared it to actual results in the 8 patients with a positive HIT. In 5, use of the predicted formula would have under-diagnosed the hypoxemia that developed during the HIT. Thus, the results of the HIT changed treatment strategy in these patients. We recommend that patients with positive tests use O2 (2LPM or 4LPM) during flight.

        HIT is practical and of potential benefit in the objective assessment of patients with various degrees of heart, lung or combined heart-lung disease. Clinicians should be aware of the relative risk of hypoxia during flight in such patients, and of the value of HIT in identifying them, leading to increase in its use.

        Dept. of Internal Medicine C, Assaf Harofeh Medical Center, Zerifin


        The adult form of mononucleosis caused by Ebstein-Barr virus (EBV) is different from the disease in children and adolescents. In most adults there is no pharyngitis or lymphadenopathy, fever is much more prolonged, abnormal liver function is frequent and lymphocytosis and the presence of atypical lymphocytes are not common. Such an atypical disease presentation often results in delayed diagnosis and unnecessary treatments. We describe 2 adults with such atypical presentations and complications of EBV infection.

        Depts. of Otolaryngology and of Head and Neck Surgery, Meir Hospital, Kfar Saba and Sackler Faculty of Medicine, Tel Aviv University; and the Israel Cancer Association Voice Rehabilitation Program


        Total laryngectomy due to malignant laryngeal tumors is followed by loss of speaking ability. Voice restoration in laryngectomized patients is the main target in their rehabilitation. Until the late 70's, esophageal speech was considered the most effective rehabilitation method. In 1980 Singer and Blom introduced a prosthesis for tracheoesophageal speech which has been gaining popularity. Tracheoesophageal puncture (TEP) can be performed either at the time of total laryngectomy, or later.

        30 of our patients underwent TEP between 1991 and 1999, 15 at the time of total laryngectomy and 15 as a delayed secondary procedure. Mean follow-up was 36 months (range 6 months to 8 years) during which all regained speaking ability.

        Over the long range, speech rehabilitation with the prosthesis was successful in 24 (80%). In only 1 in the primary TEP group did treatment fail, as the prosthesis had to be removed due to local recurrence of the tumor. Long range failure in 5/15 patients after secondary TEP stemmed from difficulties some patients had in handling the prosthesis and from psychological difficulties in adapting to the new speech device. Complications were mostly minor and occurred mainly in the secondary TEP group.

        TEP performed at the time of total laryngectomy, or later as a secondary procedure, is effective for speech rehabilitation after laryngectomy.

        Dept. of Surgery A, Wolfson Medical Center, Holon


        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.

        Acipimox as a Secondary Hypolipidemia in Combined Hypertriglyceridemia and Hyperlipidemia


        D. Yeshurun, H. Hamood, N. Morad, J. Naschitz


        Hyperlipidemia Clinic, Dept. of Medicine A, Bnai-Zion Medical Center, and Rappaport Faculty of Medicine, Technion, Haifa


        32 patients with hypertriglyceridemia, excessive hypertri- glyceridemia, and combined hyperlipidemia, were treated with the nicotinic acid derivative acipimox (Olbetam). First line treatment with bezafibrate, or statins in some with combined hyperlipidemia, had failed. In 10 acipimox was discontinued due to side effects or absence of clinical response. The other 22 completed 6 months of treatment with no side effects.

        Acipimox caused a significant 54% decrease in triglyceride levels, a 23% decrease in total cholesterol, and a 12% increase in HDL-cholesterol. LDL-cholesterol was difficult to calculate because of the high triglyceride levels, so no results are presented.

        Although acipimox was much better tolerated than nicotinic acid, it also had side effects, but fewer. Acipimox can therefor be used as a second-line drug, mainly in those with combined hyperlipidemia and hypertriglyceridemia.

        Dept. of Pediatrics, Hadassah University Hospital and Hebrew University Hadassah Medical School, Jerusalem; and Dept. of Pediatrics, Barzilai Medical Center, Ashkelon


        Acetaminophen toxicity after repeated administration of amounts that only moderately exceed recommended doses, is being increasingly reported in alcoholic or fasting adults. Pediatric experience with this pattern of acetaminophen toxicity is sparse.

        We present 2 children who developed severe hepatic damage, with renal insufficiency as well in 1, after 15-20 mg/kg of acetaminophen, given at 4-hour intervals for 3-4 days during an intercurrent febrile illness. When given in doses as low as 20 mg/kg at frequent intervals for a number of days, the drug puts children who are vomiting or have sharply reduced caloric intakes at increased risk for severe toxicity.

        Increased caution and awareness of the toxic effects of acetaminophen are needed, and it should be dispensed with appropriate package-label warnings.
