Background: Q fever is endemic in Israel, yet a large series describing the clinical spectrum of inpatients with acute Q fever in Israel is lacking. 

Objectives: To report on the clinical characteristics and outcome of hospitalized patients with acute Q fever in Israel. 

Methods: We conducted a retrospective study of 100 patients hospitalized in six medical centers, in whom acute Q fever was diagnosed by the presence of immunoglobulin G and M antibodies to phase II Coxiella burnetti antigens. 

Results: The mean age of the patients was 42.7 ± 17.3 years with a male to female ratio of 1.6:1. Acute Q fever occurred throughout the year but was more common during the warm season. The most common clinical presentation was acute febrile disease (98%, mean length of fever 15.5 ± 8.6 days), followed by hepatitis (67%) and pneumonia (32%). The prominent laboratory findings included: accelerated erythrocyte sedimentation rate, normal or low white blood count with many band forms, thrombocytopenia, and abnormal urinalysis. Although the diagnosis of acute Q fever was not known during the hospitalization in the majority of patients, about 80% of our patients received appropriate antibiotic therapy and all patients recovered. 

Conclusions: Patients with acute Q fever present with a typical clinical picture that enables clinical diagnosis and empiric therapy in most cases. The prognosis of hospitalized patients with acute Q fever is excellent.

Background: The current methods for pre‑ and post‑chemotherapy examination of the extent of disease in the breast and lymph nodes do not provide sufficiently accurate information and, not infrequently, the surgeon has to re‑operate.

Objectives: To correlate the findings between three methods of examination (physical examination, ultrasonography, mammography), all performed by the same oncologic and radiologic team, in patients with locally advanced breast cancer or a tumor/breast tissue ratio that precludes breast-conserving surgery.

Methods: Forty patients (median age 48 years, range 24–73) with locally advanced breast cancer or with a tumor/breast ratio that precluded breast‑conserving surgery were evaluated by the same medical team and received neoadjuvant chemotherapy. Surgery was performed in all, and the pathologic specimen was correlated with the results of the other examinations.

Results: In the pre‑chemotherapy evaluation, the imaging findings of the breast correlated with the physical findings in 78% of the patients and with the axilla examination in 66.7%. In the post‑chemotherapy analysis, imaging agreed with the physical findings of the breast in 62.2% and in 76.3% of the axilla. Sonography best detected occult breast disease and axillary lymph nodes but correlated with pathology in only 58% of the patients in diagnosing breast tumor and in 65.8% in diagnosing axillary lymph nodes. Mammography correlated with breast and lymph node pathology in half the patients.

Conclusions: None of the classical methods of post‑neoadjuvant chemotherapy evaluations could adequately delineate the actual extent of the disease in the breast and axillary lymph nodes. More exacting techniques of imaging combined with the classical methods are required.

Background: Physicians in the community work on a tight and often pressured schedule; verbal and non-verbal techniques to terminate the patient-physician encounter are therefore necessary.

Objectives: To characterize ways of terminating the encounter.

Methods: Using a structured questionnaire we observed seven family physicians and nine consultants and recorded patient-physician encounters to assess techniques for terminating the encounter.

Results: In all, 320 encounters were recorded, 179 (55.9%) by consultants and 141 (44.1%) by family physicians. The mean duration of the encounters was 9.02 ± 5.34 minutes. The mean duration of encounters with family physicians was longer than consultants (10.39 vs. 7.93 minutes, P < 0.001). In most cases the encounter ended with the patient receiving printed documentation from the physician (no difference between family physicians and consultants). Consultants were more likely to end the encounter with a positive concluding remark such as “feel good” or “be well” (P < 0.01). There was no single occasion where termination of the encounter was initiated by the patient.

Conclusions: Giving a printed document to the patient appears to be perceived by both patients and physicians as an accepted way to end an encounter. Another good way to end the encounter is a positive greeting such as “feel good” or “be well.”
 

Background: Debate continues in Israel as to whether to allow patients in public hospitals to choose their physician in return for an additional, out-of-pocket payment. One argument against this arrangement is that the most senior physicians will devote most of their time to private patients and not be sufficiently available to public patients with complex cases.

Objectives: To analyze the patterns of surgical seniority in Jerusalem hospitals from a number of perspectives, including the extent to which: a) opting for private care increases the likelihood of being treated by a very senior surgeon; b) public patients undergoing complex operations are being treated by very senior surgeons, c) the most senior surgeons allocate a significant portion of their time to private patients.

Methods: Demographic and clinical data were retrieved from the operating room records of three of the public hospitals in Jerusalem for all 38,840 operations performed in 2001. Of them, roughly 6000 operations (16%) were performed privately. Operations were classified as "most complex," "moderately complex" and "least complex" by averaging the independent ratings of eight medical and surgical experts. The surgeon's seniority was graded as "tenured" (tenured board-certified specialists, including department heads), "senior" (non-tenured board-certified specialists), and "residents." For each operation, we considered the seniority of the lead surgeon and of the most senior surgeon on the surgical team.

Results: The lead surgeon was of tenured rank in 99% of the most complex private cases and 74% of the most complex public cases, in 93% of the moderately complex private and 35% of the moderately complex public cases, and in 92% of the least complex private and 32% of the least complex public cases. The surgical team included a tenured physician in 97%, 66%, and 53% of the most complex, moderately complex, and least complex public operations, respectively. In both private and public cases, a board-certified (tenured or senior) specialist was a member of the surgical team for almost all of the most complex and moderately complex operations. On average, over half of the operations in which the lead surgeon was a department head were performed on public patients. Among tenured surgeons, those who spent more hours than their colleagues leading private operations also tended, on average, to spend more hours leading public operations.

Conclusions: Private patients have an advantage over public patients in terms of the seniority of the lead surgeon. However, there is also substantial involvement of very senior surgeons in the treatment of public patients, particularly in those cases that are most complex. 

Endometrial polyps are a frequent finding in infertile patients. Little is known about the true prevalence of polyps in infertile patients. It is unproved whether polyps are causative of infertility, or whether surgical polypectomy by hysteroscopy improves the likelihood of successful conception. This article reviews endometrial polyps in reproductive-age fertile and infertile women.

The adult human heart has limited regenerative capacity and, therefore, functional restoration of the damaged heart presents a great challenge. Despite the progress achieved in the pharmacological and surgical treatment of degenerative myocardial diseases, they are still considered a major cause of morbidity and mortality in the western world. Repopulation of the damaged heart with cardiomyocytes represents a novel conceptual therapeutic paradigm but is hampered by the lack of sources for human cardiomyocytes. The recent derivation of pluripotent human embryonic stem cell lines may provide a solution for this cell sourcing problem. This review will focus on the derivation of the hESC[1] lines, their mechanism of self-renewal, and their differentiation to cardiomyocytes. The possible signals and cues involved in the commitment and early differentiation of cardiomyocytes in this model will be discussed as well as the molecular, structural and electrophysiologic characteristics of the generated hESC-derived cardiomyocytes. Finally, the hurdles and challenges toward fully harnessing the potential clinical applications of these unique cells will be described.

Background: Diabetic macular edema causes visual loss in almost one-third of diabetic patients. There is currently no treatment for the accompanying cystoid foveal changes.

Objectives: To assess the clinical outcome, i.e., change in visual acuity, in patients treated with steroids for long-standing diabetic macular edema with foveal cystoid changes.

Methods: In the ophthalmology department of a tertiary care university‑affiliated medical center and the ophthalmology service of a health management organization, 46 diabetic subjects (56 eyes) who had diabetic macular edema with cystoid foveal changes received one intravitreal injection of 4 mg triamcinolone acetonide.

Results: The mean baseline (pre‑injection) visual acuity of 0.21 increased to 0.31 and 0.48 at 1 and 3 months, respectively, after which it decreased to 0.33 at 6 months. The mean intraocular pressure was 15.07 mmHg at baseline, 15.83 at day 1, gradually rising to 17.16, 18.38 and 18.57 mmHg at 1, 3 and 6 months respectively. Three patients suffered immediate visual decline after the injection.

Conclusions: Intravitreal triamcinolone acetonide may be a therapeutic option for long‑standing diabetic macular edema with foveal cystoid changes.
 

Background: Intramural duodenal hematoma generates partial or complete obstruction that develops slowly and progressively with a consequent delay in diagnosis. Many diagnostic and therapeutic measures remain debatable and justify a review of current management policy.

Objectives: To highlight the diagnostic and therapeutic steps in pediatric IDH[1].

Methods: The records of 12 children with post-traumatic IDH who were treated in the Hillel Yaffe Medical Center between 1986 and 2000 were retrospectively reviewed. Three of them had clotting disorders and were excluded. The interval between their admission and diagnosis as well as the therapeutic decisions were evaluated and analyzed.

Results: Nine children were treated for IDH. The interval between admission and diagnosis ranged from 24 hours to 6 days. Five children had associated traumatic pancreatitis. Initially, all the children were conservatively treated. In seven the hematoma resolved after 9–20 days. Two children were operated upon because the obstruction failed to resolve. All nine children recovered without permanent complications.

Conclusions: Intramural duodenal hematoma has many clinical and therapeutic puzzling aspects. Bicycle handlebar, road accidents and sports trauma are the main etiologic factors in children, but child abuse should be kept in mind. Associated traumatic pancreatitis is common. Gastroduodenal endoscopy may be useful to clarify doubtful cases. Pediatric surgeons should increase awareness regarding IDH in order to reduce delay in diagnosis and the need for surgical decompression.

The first Trauma Unit in Israel was founded at the Hadassah (Ein Kerem) Medical Center in 1992 - the result of increased awareness to the new concept of optimal care for the injured patient.

Background: Ischemic mitral regurgitation is associated with reduced survival after coronary artery bypass surgery.

Objectives: To compare long-term survival among patients undergoing coronary surgery for reduced left ventricular function and severe ischemic MR[1] in whom the valve was either repaired, replaced, or no intervention was performed.

Methods: Eighty patients with severe left ventricular dysfunction and severe MR underwent coronary bypass surgery. The mean age of the patients was 65 years (range 42–82), and 63 (79%) were male. Sixty-three (79%) were in preoperative NYHA functional class III-IV (mean NYHA 3.3), and 26 (32%) were operated on an urgent/emergent basis. Coronary artery bypass surgery was performed in all patients. The mitral valve was repaired in 38 and replaced in 14, and in 28 there was no intervention. The clinical profile was similar in the three groups, although patients undergoing repair were slightly younger.

Results: Operative mortality was 15% (8%, 14%, and 25% for the repair, replacement and no intervention respectively; not significant). Long-term follow up was 100% complete, for a mean of 38 months (range 2–92). Twenty-nine patients (57%) were in NYHA I-II (mean NYHA 2.3). Among the surgery survivors, late survival was improved in the repair group compared to the other groups (P < 0.05). Predictors for late mortality were non-repair of the mitral valve, residual MR, and stroke (P = 0.005).

Conclusions: Patients with severe ischemic cardiomyopathy and severe MR undergoing coronary bypass surgery should have a mitral procedure at the time of surgery. Mitral valve repair offers a survival advantage as compared to replacement or no intervention on the valve. Patients with residual MR had the worst results.

Background: Lipoid pneumonia is a pneumonitis resulting from the aspiration of lipids, and is commonly associated with the use of mineral oil as a laxative. LP[1] is relatively unfamiliar to clinicians and is probably underdiagnosed.

Objectives: To increase physicians' awareness of LP, its diagnosis and prevention.

Methods: We present two illustrative cases of LP and review the literature.

Results: Two cases of LP were diagnosed within half a year in an internal medicine ward. Both cases were elderly patients, and LP was associated with the use of mineral oil as a laxative agent. Computerized tomography revealed bilateral low attenuation infiltrates, associated with a "crazy paving" pattern in one case. Sudan Black staining was diagnostic in both cases – in one on a transbronchial biopsy specimen, and in the other on sputum cytologic examination. Both patients suffered from neurologic diseases and were at risk of aspiration. In both cases clinical symptoms and signs continued for several months prior to diagnosis but resolved after the mineral oil was discontinued.

Conclusions: LP often occurs in elderly patients who are at risk of aspiration. The condition may be underdiagnosed. Since in most cases mineral oil cathartics are the causative agent, an effort at primary prevention is indicated. It is suggested that the licensing of mineral oil for internal use be changed.
