Background: Multidrug-resistant tuberculosis (MDR-TB) presents a difficult therapeutic problem due to the failure of medical treatment. Pulmonary resection is an important adjunctive therapy for selected patients with MDR-TB.

Objectives: To assess the efficacy of pulmonary resection in the management of MDR-TB patients.

Methods: We retrospectively reviewed the charts of MDR-TB patients referred for major pulmonary resections to the departments of thoracic surgery at Assaf Harofeh and Wolfson Medical Centers. For the period under study, 13 years (from 1998 to 2011), we analyzed patients’ medical history, bacteriological, medical and surgical data, morbidity, mortality, and short-term and long-term outcome.

Results: We identified 19 pulmonary resections (8 pneumonectomies, 4 lobectomies, 1 segmentectomy, 6 wedge resections) from among 17 patients, mostly men, with a mean age of 32.9 years (range 18–61 years). Postoperative complications developed in six patients (35.3%) (broncho-pleural fistula in one, empyema in two, prolonged air leak in two, and acute renal failure in one). Only one patient (5.8%) died during the early postoperative period, three (17.6%) in the late postoperative period, and one within 2 years after the resection. Of 12 survivors, 9 were cured, 2 are still under medical treatment, and 1 is lost from follow-up because of poor compliance.

Conclusions: Pulmonary resection for MDR-TB patients is an effective adjunctive treatment with acceptable morbidity and mortality.
 

Background: There is a striking increase in the number of people with metabolic syndrome (MetS) as a result of the global epidemic of obesity and diabetes. Increasing evidence suggests that uric acid may play a role in MetS.

Objectives: To assess the prevalence of MetS in a large cohort from Israel and its association with hyperuricemia using the latest three definitions of MetS.

Methods: We conducted a retrospective analysis of the database from a screening center in Israel, using the revised National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), the International Diabetes Federation (IDF) and the Harmonizing definitions of MetS, to assess 12,036 subjects with an age range of 20–80 years.

Results: The mean age of the study sample was 46.1 ± 10.2 years and 69.8% were male. The prevalence of MetS was 10.6%, 18.2% and 20.2% in the revised NCEP ATP III, the IDF and the Harmonizing definitions respectively. The prevalence of hyperuricemia in subjects with MetS, for all three MetS definitions, was similar: 20.0%, 19.9% and 19.1% respectively. There was a graded increase in the prevalence of MetS among subjects with increasing levels of uric acid. The increasing trend persisted after stratifying for age and gender and after multivariate analysis (P for trend < 0.001).

Conclusions: This large cohort shows a high prevalence of MetS in Israel, but is still lower than the prevalence in western countries. Hyperuricemia is common in those subjects and might be considered a potential clinical parameter in the definition of MetS.
 

Current treatments for systemic lupus erythematosus (SLE) are effective in reducing morbidity and mortality but are not specific and have severe adverse effects. Based on understanding of the different dysregulated immunological pathways involved in SLE pathogenesis, specific targeted therapies were developed. This review presents the current and the near-future novel biological immune targeted treatments, such as B cell-targeted therapy, cytokine blockade, peptide-based treatments and other novel treatments for SLE.
 

Background: Intraarticular injections for the local treatment of osteoarthritis are widely used in the office or hospital setting. Septic arthritis is a potential catastrophic complication of intraarticular injection, as bacterial arthritis of any cause is associated with up to 15% mortality and residual impairment of joint function in up to 50% of survivors. There is lack of evidence regarding the precautions that should be taken to avoid such a complication, as well as how often it is encountered.

Objectives: To report our experience with the clinical presentation, diagnosis and treatment of knee septic arthritis following intraarticular injections. 

Methods: We followed six patients who were admitted to the hospital and underwent surgery for the treatment of pyogenic arthritis following injection to the knee joint in outpatient clinics.

Results: All but one patient were over 70 years old with comorbidities. Three patients were injected with steroid preparations and three with hyaluronic acid several days before admission. In all six patients the infection was treated surgically and three of them had undergone more than one operation during their hospitalization. Four of the six patients were treated by means of an open arthrotomy and synovectomy, and the other two were treated successfully with arthroscopic lavage and synovectomy. One patient underwent an above-knee amputation due to septic shock and died after several days.

Conclusions: Despite the rarity of this complication, surgeons must be aware of the possibility of pyogenic arthritis when administering injections, especially in elderly patients with serious underlying medical conditions.

Background: The treatment of rectal cancer has changed significantly over the last few decades. Advanced surgical techniques have led to an increase in the rate of sphincter-preserving operations, even for low rectal tumors. This was facilitated by preoperative oncologic treatment and the use of chemoradiation to downstage the tumor before resection. The introduction of total mesorectal excision further improved the oncologic outcome and became the standard of care. The use of laparoscopy for rectal resection is the most recent addition to this series of improvements, but in contrast to the use of laparoscopy in colon cancer its role is not yet well defined.

Objectives: To present our experience with laparoscopic surgery for upper and lower rectal tumors.

Methods: A database was used to prospectively collect all data on laparoscopic rectal surgery in our department since we started performing these procedures in 1997. Follow-up data were collected from outpatient clinic visits, oncology files and telephone interviews. Updated survival data were retrieved from the national census.

Results: Of 750 laparoscopic colorectal procedures performed over a 13 year period, 67 were for rectal cancer. Of these, 29 were resections for tumors in the upper rectum (11–15 cm from the anal verge) and 38 for tumors at 10 cm or below. Surgery was performed in 24 patients after neoadjuvant chemoradiation. There were 54 sphincter-preserving operations and 13 abdominoperineal resections. The mean operative time was 283 minutes. Conversion to an open procedure was required in 22% of the cases. Anastomotic leaks occurred in 17% of cases. Postoperative mortality was 4.5%. Long-term follow-up was available for 77% of the group, for a mean period of 42 months. Local recurrence was diagnosed in 4.5% of the patients and overall 5 year survival was 68%.

Conclusions: Laparoscopic rectal resection is a demanding procedure. However, laparoscopy may become the preferred approach since it is a minimally invasive procedure and has an acceptable oncologic outcome that is comparable to the open approach. This conclusion, however, needs further validation.
 

Background: A new approach for assessing non-cognitive attributes in medical school candidates was developed and implemented at the Hebrew University Medical School. The non-cognitive tests included a biographical questionnaire, a questionnaire raising theoretical dilemmas and multiple mini-interviews.

Objectives: To evaluate the effects of the change in the admission process on students' demographics and future career choices.

Methods: A questionnaire including questions on students’ background and future residency preferences was administered to first-year students accepted to medical school by the new admission system. Results were compared with previous information collected from students admitted through the old admission process.

Results: Students accepted by the new process were significantly older (22.49 vs. 21.54, P < 0.001), and more had attended other academic studies before medical school, considered other professions besides medicine, and majored in humanities combined with sciences in high school. Significantly more students from small communities were admitted by the new system.  Differences were found in preferences for future residencies; compared with the old admission process (N=41), students admitted by the new system (N=85) had a more positive attitude towards a career in obstetrics/gynecology (41% vs. 22%, P < 0.001) and hematology/oncology (11.7% vs. 4.8%, P < 0.001), while the popularity of surgery and pediatrics had decreased (34.5% vs. 61%, P < 0.001 and 68.7% vs. 82.5%, P < 0.001 respectively).

Conclusions: Assessment of non-cognitive parameters as part of the admission criteria to medical school was associated with an older and more heterogenic group of students and different preferences for future residency. Whether these preferences in first-year students persist through medical school is a question for further research.
 

Background: Familial dysautonomia is a hereditary disease characterized by dysfunction of the sensory and autonomic nervous systems. Studies in patients with familial dysautonomia have shown that abnormal cardiac autonomic denervation might influence repolarization. Autonomic tone also affects atrial conduction parameters and P-wave dispersion, which are predictive of atrial fibrillation.

Objectives: To examine the possible association of familial dysautonomia with abnormal atrial conduction and P-wave dispersion.

Methods: The study population included 12 patients with familial dysautonomia and age and sex-matched control subjects. All participants underwent a 12-lead electrocardiogram under strict conditions. P-wave lengths and P-wave dispersion were computed from a randomly selected beat and an averaged beat using designated computer software.

Results: There were no statistically significant differences between the groups in minimal, maximal, and average P-wave duration or P-wave dispersion for a randomly selected beat. P-wave dispersion for an averaged beat was also similar. During 6 months follow-up, no supraventricular arrhythmias were documented in either group.

Conclusions: We found that patients with familial dysautonomia had P-wave dispersion parameters not significantly different from those of controls. Further research is required to clarify the effects of dysautonomia on atrial conduction in familial dysautonomia.

The courts have recently become increasingly involved in the administration of compulsory psychiatric services in Israel. Data reveal a gradual increase in the rate of court-ordered hospitalizations according to Section 15 of the Law for the Treatment of the Mentally Ill. This paper examines the implications of this trend, particularly the issues of security and safety in psychiatric hospitalization. We present highlights from extensive British experience, focusing on the implications on forensic psychiatry in Israel. We review the development of the hierarchy of security in the British psychiatric services, beginning in the early 1970s with the establishment of the Butler Committee that determined a hierarchy of three levels of security for the treatment of patients, culminating with the establishment of principles for the operation of medium security units in Britain (Read Committee, 1991). These developments were the basis for the forensic psychiatric services in Britain. We discuss the relevance of the British experience to the situation in Israel while examining the current status of mental health facilities in Israel. In our opinion, a safe and suitable environment is a necessary condition for a treatment setting. The establishment of medium security units or forensic psychiatry departments within a mental health facility will enable the concentration and classification of court-ordered admissions and will enable systemic flexibility and capacity for better treatment, commensurate with patient needs.
