Background: An estimated 10% of all children are subject to recurrent attacks of abdominal pain of unknown origin. When no organic cause is found, the working diagnosis is usually functional abdominal pain.

Objectives: To investigate the possible causative role of occult constipation.

Methods: We defined occult constipation as the absence of complaints of constipation on initial medical history or of symptoms to indicate the presence of constipation. The diagnosis was made by rectal examination and/or plain abdominal X-ray.

Results: Occult constipation was found to be the cause of RAP[1] in 42.6% of children examined. Treatment consisted of paraffin oil and phosphate enema. In 82.84% of cases the abdominal pain subsided considerably or disappeared within 2 weeks to 3 months of treatment. On telephone interview of the parents at 1–1.5 years after discharge, 96.5% reported that both the abdominal pain and constipation had subsided or disappeared.

Conclusions: Occult constipation can be easily identified and treated in a large number of children with RAP who were diagnosed as having functional abdominal pain.

Background: The long-standing and ongoing controversy regarding administration of analgesia to patients with acute abdominal pain prior to final diagnosis has not yet been resolved, despite considerable research. Consequently, wide variations in clinical practice exist.

Objectives: To determine the motives, attitudes and practices of emergency physicians, internists and surgeons in Israeli emergency departments regarding the administration of analgesia before diagnosis in patients with acute abdominal pain.

Methods: Questionnaires were completed by 122 physicians in 21 EDs[1] throughout Israel and the replies were analyzed.

Results: Most EDs did not have a clear policy on analgesia for undifferentiated abdominal pain, according to 65% of the responders. More internists (75%) than surgeons (54%) (P = 0.02) and more emergency physicians (81%) than all other physicians (60%) (P = 0.05) held this opinion. Most respondents (64%) supported administration of analgesia pre-diagnostically. Support for analgesia was significantly stronger among internists (75%) compared to surgeons (52%) (P = 0.03). Despite this wide support, most respondents (68%) indicated that analgesia was rarely or never given pre‑diagnostically and, when it was, more surgeons (58%) than other physicians made that decision. Most internists (73%) and all surgeons reported that patients receive analgesia only after being examined by surgeons. Time allocated to the ED (part‑ or full‑time) significantly (P = 0.02) influenced decision-making, with 51% of part-time physicians vs. 25% of full-time opposing prompt administration of analgesia. Opinions on who should decide were divided according to medical specialty, with surgeons and internists almost opposed, as well as by physician age and percent of his/her time spent working in the ED. More surgeons than internists (P = 0.0005) reported that analgesia sometimes interfered with making a diagnosis. Most physicians (90%) stated that opiates impede diagnosis, to some extent. However, 58% of them supported the administration of opiates, more or less frequently. Intramuscular diclofenac was the most preferred analgesic, followed by intravenous morphine and pethidine; individual preferences extended beyond the list of actually administered drugs.

Conclusions: There is no consensus on the administration of analgesia for undiagnosed acute abdominal pain in EDs in Israel. Physicians’ attitudes are influenced by training, experience, and percent of personal time allocated to work in the ED.

Obstructive sleep apnea syndrome is a major public health hazard affecting 2–4% of the adult population; only 10% of these patients are recognized by healthcare providers. In the last decade the number of referrals for polysomnography increased threefold in Israel, compared to 12-fold worldwide, and is expected to increase even more in the coming years. This constant demand for PSG[1] studies is beyond the current capacity of sleep laboratories, thus preventing diagnosis for most patients with suspected OSAS[2]. In the current review, we examine problems facing decision-makers on how to treat the increasing flood of patients presenting with symptoms suggestive of sleep-disordered breathing. We evaluate the cost-effectiveness of current technologies for OSA diagnosis, i.e., laboratory versus at-home technologies. We conclude that no current alternative exists to the use of PSG for OSA diagnosis. When at-home technologies are suggested for OSAS diagnosis, data should be provided on factors influencing its cost-effectiveness, e.g., accuracy rates of diagnosis, relative cost of human resources, and case-mix of patients tested. Since PSG remains the gold standard for diagnosis of OSAS, in Israel resources should be allocated to increasing the volume of beds for PSG studies in order to increase access to diagnosis and treatment, which in turn provides better quality of life, saves scarce resources of the healthcare system, prevents unnecessary accidents and increases workers’ productivity.

Background: Left main coronary artery disease is considered a surgical indication in most centers. However, in some cases prohibited from surgery or in patients with prior bypass grafting, there is a need for percutaneous coronary intervention in LMCA[1] disease scenarios.

Objectives: To assess the clinical outcomes among patients undergoing stent-based LMCA angioplasty.

Methods: We identified 34 consecutive patients who underwent PCI[2] in LMCA at our institution. Procedural data and clinical outcomes were obtained for all patients.

Results: The mean age was 71 ± 12 years. There were 27 elective and 7 emergent procedures performed on 23 “protected” LMCA and 11 “unprotected” LMCA. In emergent procedures, the prevalence of cardiogenic shock (29% vs. 0%, P = 0.04) in patients with prior coronary bypass (29% vs. 8.5%, P = 0.007) was significantly higher compared to elective cases. Procedural success in emergent procedures was significantly lower than in elective procedures (71 vs. 100%, P = 0.04). In emergent versus elective procedures, the in-hospital mortality rate was higher (43 vs. 0%, P = 0.006). The rate of cumulative major adverse cardiac events at 1 and 6 months was 43% and 71% in emergent cases versus 0% and 33% in elective cases (P < 0.05 for both comparisons). In patients with “unprotected” LMCA the overall major cardiac events at 1 month was higher compared to “protected” LMCA patients (27 vs. 0%, P = 0.02). Multivariate analysis revealed emergent procedure as an independent predictor for mortality and adverse cardiac events (odds ratio 6.7; 95% confidence interval 1.2–36; P = 0.02).

Conclusions: Percutaneous interventions in LMCA are feasible and relatively safe in carefully selected cases. Procedural outcomes and clinical prognosis is highly dependent on the nature of disease prior to angioplasty (e.g., elective vs. emergent procedure) as well as on protection of the LMCA by patent grafts.

Background: Various medical centers in Israel have recently incorporated electronic medical record systems. Knowing the EMR[1] systems’ features and pattern of use is an essential step for developing locally and nationally integrated systems.

Objectives: To evaluate the status of EMR systems in all major general hospitals in Israel in terms of the applications used and the patterns of use.

Methods: Structured questionnaires were sent to hospital directors and directors of medical informatics units of 26 general and pediatric hospitals serving the vast majority of the population in Israel. The qheuestionnaire included questions pertaining to the EMR systems, their usage and the attitude of the participants to data security issues.

Results: Of the 26 general hospitals 23 (88.4%) returned the questionnaires. Of these, 21 (91.3%) use EMR systems. Twenty-seven different types of systems are in use in Israeli hospitals, and generally more than one type is used in a hospital. [YD1] Physicians work with EMR systems in over 98% of the departments. Also, the EMR systems are used for clinical admission and discharge in over 90% of the departments and for medical daily follow-up in about 45%.

Conclusions: Most of the hospitals in Israel use EMR systems but there is no standard data model. Physicians are the main users but the amount of data entered is still limited. Adoption of standards is essential for integration of electronic patient records across Israeli healthcare organizations.

Background: Until recently trimethoprim-sulfamethoxazole was the drug recommended in the Leumit Health Fund for the empiric treatment of uncomplicated urinary tract infection in women. However, due to increased uropathogen resistance to this drug, the fund has designated nitrofurantoin as its new drug of choice.

Objectives: To evaluate the potential economic impact of implementing this new pharmaco-policy.

Methods: Using data derived from the electronic patient records of the Leumit Health Fund we identified all non-recurrent cases of women aged 18–49 with a diagnosis of acute cystitis or UTI[1] without risk factors for complicated UTI and empirically treated with antibiotics throughout 2003. The final sample comprised 5,489 physician-patient encounters. The proportion of cases treated with each individual drug was calculated, and the excess expenditure due to non-adherence to the new guideline from the perspective of the health fund was evaluated using 5 days of therapy with nitrofurantoin as the reference treatment.

Results: Ofloxacin was the most frequently prescribed drug (30.24%), followed by TMP-SMX[2] (22.43%), cephalexin (15.08%), and nitrofurantoin (12.59%). The observed net aggregate drug expenditure was 2.3 times greater than expected had all cases been treated with nitrofurantoin according to the guideline duration of 5 days. The cost of treatment in 53% of the cases exceeded the expected cost of the guideline therapy.

Conclusions: Successful implementation of the new drug policy will likely improve quality of care and reduce costs to the health fund.
