Background: Cardiac rupture is a rare but ominous complication of myocardial infarction.

Objectives: To study the clinical presentation, medical course, outcome and echocardiographic predictors of patients with myocardial rupture.

Methods: We evaluated 15 consecutive patients with cardiac rupture during a 4 year period in our department. The current report explores the presence of potential risk factors, timing, relation to the thrombolysis, coronary interventions and outcome.

Results: The index event in all patients was first ST elevation myocardial infarction. In seven patients rupture occurred in the first 24 hours. Pericardial effusion on admission with a clot was present in three patients. Five patients received thrombolytic therapy. Only three patients underwent coronary angioplasty, but in one case it was performed late and in two patients the culprit artery could not be opened. Six patients reached the operating room, of whom three survived.

Conclusions: The lack of early mechanical reperfusion in acute myocardial infarction and thrombolytic therapy are risk factors for cardiac rupture. Pericardial effusion on admission and evidence of a clot are echocardiographic indicators of cardiac rupture and should alert the medical team to further assess the possibility of cardiac rupture.
 

Background: In patients with Graves’ ophthalmopathy, orbital decompression surgery is indicated for compressive optic neuropathy, severe corneal exposure, or for cosmetic deformity due to proptosis. Traditionally this has been performed through a transantral approach, but the associated complication rate is high. More recently, endoscopic orbital decompression has been performed successfully with significantly fewer postoperative complications.

Objective: To report our experience of endoscopic orbital decompression in patients with severe Graves’ ophthalmopathy.

Methods: Three patients (five eyes) underwent endoscopic orbital decompression for Graves’ ophthalmopathy at Soroka Medical Center between the years 2000 and 2002. The indications for surgery were compressive optic neuropathy in three eyes, severe corneal exposure in one eye, and severe proptosis not cosmetically acceptable for the patient in one case. An intranasal endoscopic approach with the removal of the medial orbital wall and medial part of the floor was performed.

Results: In all five eyes an average reduction of 5 mm in proptosis was achieved. Soon after surgery, visual acuity improved in the three cases with compressive optic neuropathy, and exposure keratopathy and cosmetic appearance improved. The diplopia remained unchanged. No complications were observed postoperatively.

Conclusions: Endoscopic orbital decompression with removal of the medial orbital wall and medial part of the floor in the five reported eyes was an effective and safe procedure for treatment of severe Graves’ ophthalmopathy. A close collaboration between ophthalmologists and otorhinolaryngologists skilled in endoscopic sinus surgery is crucial for the correct management of these patients.

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.
