Streptococcus pneumoniae is an important cause of pediatric morbidity and its main reservoir is the nasopharynx, from which it can disseminate and cause invasive disease. From November 1997 through March 1998, nasopharyngeal carriage of S. pneumoniae was evaluated in 250 children under the age of 36 months: 123 Jews and 127 Bedouins with acute respiratory disease and in 980 healthy control children (852 Jews and 128 Bedouins).

Carriage rate was higher among sick children. Among Jewish children it was 57% and 35% of sick and healthy children respectively (p<0.01), and among Bedouin children it figured as 80% and 67% respectively (p=0.01). The difference in carriage rate was most prominent in infants under the age of 5 months: among Jewish children it was 60% and 27% of sick and healthy children respectively (p<0.001) and among Bedouins it was 82% and 65% respectively (p=0.05).

Higher carriage rate of penicillin resistant pneumococci (PRP) was also detected in sick children, with no relation to antibiotic treatment in the month prior to sampling. In Jewish children PRP was detected in 12%, 28% (p<0.001) and 36% (p<0.001) of healthy children, sick children with previous antibiotic treatment and sick children with no treatment, respectively.

The seroypes included in the newly developed 7-valent conjugate vaccine: 4, 6B, 9V, 14, 18C, 19F, 23F, that are highly pathogenic and often antibiotic resistant contributed 74% of isolates in sick Jewish children who had previous antibiotic treatment and 39% of isolates in healthy children (p<0.001). In Bedouin children vaccine types carriers rate among the sick children was not higher than in healthy children.

Acute respiratory disease increases the risk of pneumococcal carriage in general and carriage of resistant pneumococci in particular. Previous antibiotic treatment increases the risk of carring one of the pathogenic serotypes included in the 7-valent vaccine. The impact of disease is most prominent in infants under 5 months, since they are usually less exposed to S. pneumoniae carriers than older children.

Since the increase in carriage rate during illness is mostly due to the serotypes included in the newly developed conjugate vaccine, future immunization programme may decrease not only morbidity rate but also nasopharyngeal carriage rate of pneumococci in general and of antibiotic-resistant pneumococci in particular.

In order to examine the effect of reflux therapy on Hyper Reactive Airway Disease (HRAD) and apnea severity, 107 children, 78 with HRAD and 29 with apnea, underwent pH monitoring in the Pediatric Surgery Unit of Wolfson Hospital and the Dana Children's Hospital during the years 1995-1998. Pathological reflux was defined by means of the Boix-Ochoa and RI (Reflux Index) scores. In patients with positive reflux, anti-reflux treatment was initiated. Prior to and following pH monitoring, the respiratory status of all patients (both with and without reflux) was evaluated by a pediatric pulmonologist employing commonly used scores to determine severity.

Results: Subject age ranged between one day and 15 years (mean: 15.44±29 months, median: 6.37 months). In HRAD, following anti-reflex treatment the reflux positive group showed a significant score improvement, from an average of 2.9±1.1 units to 1.54±1.2 units (p<0.0001); a decrease in the number of patients treated with oral corticosteroids (p<0.01); a close to significant decrease (p=0.069) in the average dose of inhaled corticosteroids; and a decrease in the number of patients using bronchodilators (p=0.042). The reflux-negative group, not treated for reflux, displayed no significant improvement, with only a decrease in the severity scores from 2.44±1.0 to 1.78±1.2 units (p=0.14), and no change on any of the other parameters.

In apnea, all patients improved, from an average score of 2.34±0.77 to 0.03±0.19 units (p<0.0001), with no significant difference between the reflux positive and the reflux negative groups.

In view of these findings, it is postulated that anti-reflux therapy may have an additive effect on HRAD severity, beyond that of spontaneous respiratory improvement. We therefore find it appropriate for every severe HRAD patient (frequent exacerbations or high corticosteroid dose) to undergo pH monitoring in order to treat those with proven reflux. In respect to apnea, we cannot attribute any significance to the existence of reflux or to anti-reflux treatment.

Intraventricular hemorrhage in full-term neonates is rare; it may develop without any clinical signs. Its cause is not fully understood although some risk factors have been identified. A higher index of suspicion would ensure earlier diagnosis and treatment, which might reduce the rate of severe complications. We describe 2 cases in full-term neonates.

Gastrointestinal bleeding of obscure origin consists of recurrent bouts of acute or chronic bleeding for which no definite source is discovered in routine endoscopic and barium contrast studies of the upper and lower gastrointestinal tracts. Usually its cause is angiodysplasia of the intestine, but many cases are due to tumors, mostly of the small bowel, which may be malignant.

In patients under the age of 50, the proportion with malignancy is relatively high (up to 14%) as compared to older patients. We describe a 45-year-old woman who suffered from gastrointestinal bleeding for 3 years. The cause of bleeding was not found despite extensive work-up.

In her last admission for acute gastrointestinal hemorrhage she was given a total of 30 units of blood. A tumor of the small intestine found by angiography was excised and found to be a stromal tumor of uncertain malignant potential. 1 year after operation she is asymptomatic without bleeding and her hemoglobin is stable without treatment.

Non-Penetrating Deep Sclerectomy without Collagen Implantfor Glaucoma

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.

Many drugs used in children are based on pharmacological data obtained in adults. Therefore, many drugs are either unlicensed for use in children or are prescribed outside the terms of the product license (off-label). This pilot study assessed use of unlicensed or off-label drugs in hospitalized children.

Drug orders of patients admitted to a general pediatric ward were reviewed retrospectively in a random sample. Assessment was based on the data of the Physicians' Desk Reference and the Israel Drug Compendium. 80 different drugs and 278 drug orders were written for 92 patients (0.5 months - 11 years old, mean 26.9 months) in 97 admissions. Of these 52.9% were either off-label or unlicensed. Patients received 1 or more unlicensed or off-label drugs in 64.9% of admissions. They were more often off-label than unlicensed. The main reasons for use of off-label drugs were unusual doses and inappropriate age. The main reason for unlicensed drugs was modification of a particular formulation of a licensed drug.

This pilot study indicates that use of drugs in an off-label or unlicensed manner in children is probably quite frequent in Israel. Our data emphasize the need for licensing a large number of drugs for use in children, based on the same scientific principles as in adults. Further collaborative studies in different pediatric centers in Israel, involving different types of pediatric settings (ambulatory and in-hospital), is required to evaluate comprehensively the magnitude of this preliminary finding.

We assessed the prevalence of self-reported medical complaints among the community-dwelling elderly receiving regular medication, and determined associations between health and sociodemographic variables, and the prevalence of complaints.

The study included 170 patients, 60-90 years of age, living at home. Participants were recruited from the 3 main primary care clinics in Rishon LeZion. All were receiving chronic medication and were followed-up utilizing a long-term medication card. Data were gathered in interviews held in patients' homes using a structured questionnaire which included sociodemographics, diseases and medication, mental state assessment by Katzman's score, and a list of 15 medical complaints common among the aged. Relations to age, gender, education, living arrangements, number of diseases and number of medications per patient were determined.

Mean age of participants was 73.2±6.0 years and they suffered an average of 4.07±2.16 diseases and took 5.10±2.83 types of drugs. The most prevalent complaints were: weakness and fatigue (65.0%), agitation and restlessness (56.4%), dry mouth (45.6%), constipation (43.6%) and dizziness (43.2%). The number of diseases, gender, education and age had the strongest associations with the prevalence of specific complaints, as well as their total number. The association between number of medications and mean number of complaints was of borderline significance.

The usual treatment of complicated neonatal necrotizing enterocolitis (NEC) is resection of the necrotic bowel, lavage of the peritoneal cavity and diversion enterostomy. Low-birth-weight premature neonates with this condition are in special danger if general anesthesia and full exploratory surgery is contemplated.

A relatively simple alternate procedure is percutaneous insertion under local anesthesia of a soft abdominal drain, most often in the right lower quadrant. The procedure is done in the neonatal intensive care unit without moving the whole set-up to the operating room.

4 such cases have been treated within the past year. 3 were discharged home as they did not require additional surgical treatment, not having developed intestinal stenosis or obstruction. 1 recovered from the acute episode, but succumbed to a severe intraventricular hemorrhage and respiratory failure 7 days after the procedure.

Our limited but most gratifying experience, in addition to similar experience of others, encourages us to recommend this simple surgical approach in the very sick low-birth-weight premature with fulminant NEC.

Danaparoid-Sodium for Dialysis in Heparin-Associated Thrombocytopenia

Danaparoid sodium is an anticomposed of 3 glycosaminoglycans: heparan sulfate, dermatan sulfate and chondroitin sulfate. Similar to heparin, operates by activating antithrombin 3, but does not contain heparin or heparin fragments, and is therefore antigenically distinct.

Danaparoid has been advocated as a safe and effective anticoagulant for heparin-associated thrombocytopenia. However, there is little experience in its use as a substitute for heparin in hemodialysis.

We report 2 men, aged 82 and 73 years, respectively, who developed thrombocytopenia while undergoing hemodialysis with heparin, and who subsequently underwent successful dialysis with danaparoid. There was a rise in platelet levels in both while receiving danaparoid, and dialysis was completed without hemorrhagic or thrombotic complications. Danaparoid is a safe and effective substitute for heparin, and may be used as an anticoagulant in hemodialysis.

A 42-year-old man was admitted for fever and severe low back pain radiating to both legs. On MRI, an epidural spinal abscess from S1 to D10 was seen. Treatment included laminectomy, drainage of the abscess and antibiotics. Recovery was complete without neurological damage. Increased awareness of this disease may lead to diagnosis and treatment.

Nonpenetrating Deep Sclerectomy

Orna Geyer

Ophthalmology Dept., Tel Aviv-Sourasky Medical Center

This is the first report from Israel of nonpenetrating deep sclerectomy (DS), a new operation for the surgical management of glaucoma. It facilitates ocular fluid drainage without entering the eye. It involves performance of a conjunctival flap and creation of a 565 mm superficial scleral flap. A deeper scleral flap is dissected off the scleral bed together with the roof of the canal and corneal stroma, leaving behind the wall of the canal and membrane. Aqueous will flood the dissected area. A collagen device is then sutured to the scleral bed, the superficial scleral flap sutured into position and the conjunctiva closed. With this procedure, the surgeon can avoid the common complications of conventional glaucoma surgery.

We report a 6-month follow-up of 15 patients after DS. Mean preoperative intraocular pressure was 26.7+2.5 mm Hg, which decreased to 15.5+4.7. After 6 months there was no change in visual acuity after surgery. DS is associated with good middle-term intraocular pressure control and a low rate of postoperative complications. It is therefore a good alternative to standard glaucoma surgery.

Medical Corps, Israel Defense Forces and Sheba Medical Center, Tel Hashomer

During 1994/5 the Japanese civilian population suffered 2 terror attacks by the organophosphorus nerve-agent sarin. In these 2 episodes it is estimated that more than 6000 people were injured, of whom 19 died. The quick and efficient response of the civilian emergency systems to these unforseen, attacks has to be analyzed by local authorities to determine the best solutions in case of another attack. We summarize the events, and note the emergency system's response, the need for rapid and accurate chemical identification of the toxin, the necessity for decontaminating the casualties and for providing protective gear for rescue units in the contaminated area. We also describe the clinical status of the casualties and outline the mode of therapy applied.

Multiple Angiodysplastic Lesions of the Colon - a Therapeutic Challenge

Division of Gastroenterology and Dept. of Medicine E, Soroka Medical Center and Ben-Gurion University, Beer Sheba

Colonic angiodysplasia is one of the most frequent causes of recurrent lower gastrointestinal tract bleeding, mainly in the elderly. In 50% of patients multiple angiodysplastic lesions were reported when they were the cause of rectal bleeding. Bleeding from angiodysplasia is more severe and less responsive to treatment in those with coagulation disorders. A 74-year-old woman with an artificial mitral valve who was treated with coumadine is reported. A few years after operation she began to develop severe recurrent rectal bleeding because of multiple angiodysplastic lesions along the right colon, proven by colonoscopy. She was frequently hospitalized for blood transfusions; endoscopic treatment was not feasible and the surgical risk of colectomy was very high. Treatwith estrogen and progesterone significantly decreased recurrent episodes of bleeding.

Early Results with Threaded Spinal Cage Fusion Systems

Lumbar interbody fusion is a surgical technique used to treat symptomatic lumbar disc disease. Low back disorders are the most common of the musculoskeletal disorders causing a tremendous burden of disability. One of the causes of low back pain and radiculopathy is spinal instability, which can be treated by spinal fusion. In the past year, threaded cage systems have become available for segmental lumbar fusion for degenerative disc disease. These systems offer several biomechanical advantages over traditional lumbar fusion and instrumentation techniques, and are better tolerated.

From December 1996 until June 1997 we operated and fused spines of 17 patients, using 2 different fusion systems (anterior and posterior approaches). We present our early results.
