Background: Successful neuraxial block performance relies on assessment and palpation of surface landmarks, potentially challenging in patients with high body mass index (BMI). 

Objectives: To evaluate the use of ultrasound-assisted neuraxial bock in a non-obstetric population with BMI above versus below 30 kg/m2.

Methods: Healthy adult patients undergoing extracorporeal shock wave lithotripsy (ESWL) under neuraxial block were observed in this quality assurance study. Prior to the neuraxial block, an ultrasound examination was performed to identify the puncture site. Neuraxial anesthesia block was performed under aseptic surgical conditions with the patient in the sitting position. Following block placement, external landmarks were palpated. Our primary study outcome was the number of attempts (skin insertions with the needle) after pre-puncture ultrasound identification of the insertion point, comparing patients with BMI above versus below 30 kg/m2. Our secondary outcome was assessment by palpation of external anatomical landmarks.

Results: Our study group included 63 consecutive patients undergoing neuraxial block for ESWL. Data were assessed according to BMI (above versus below 30 kg/m2). An overall success rate at the first attempt of 90.5% (CI 0.8–0.95) was achieved using ultrasound-guided neuraxial block. This block placement success rate was similar for all patients, regardless of BMI above versus below 30 kg/m2. In contrast, the ease of palpation of anatomic landmarks, P = 0.001, and the ease of palpation of iliac crest, P < 0.001, differed significantly between the patients above versus below 30 kg/m2. The reported verbal pain scores (VPS) due to block insertion was similar among all patients regardless of BMI category (above versus below 30 kg/m2).

Conclusions: We observed high success rates when ultrasound-assisted neuraxial block is performed, regardless of BMI above versus below 30 kg/m2, despite expected differences in surface landmark palpation. 

 

Background: Trans-catheter valve implantation (TAVI) is a non-surgical alternative for patients with severe aortic stenosis (AS). Pre-procedural computed tomography angiography (CTA) allows accurate “road mapping,” aortic annulus sizing and the detection of incidental findings.

Objectives: To document the prevalence of non-valvular extra-cardiac findings on CTA prior to TAVI and the impact of these findings on the procedure.  

Methods: Ninety AS patients underwent CTA as part of pre-TAVI planning. Scans extended from the clavicles to the groin. Non-vascular non-valvular findings were documented and graded as follows: (A) significant findings causing TAVI cancellation or postponement, (B) significant findings leading to a change in the TAVI procedure approach, (C) non-significant findings not affecting the TAVI procedure. 

Results: TAVI was planned for 90 patients; their average age was 80.2 ± 7.5 years, 53% were females. Overall, non-valvular cardiac, extra-cardiac and extra-vascular significant and non-significant incidental findings were documented in 97% of scans (87/90). Significant pathologies causing TAVI cancellation or postponement (category A) were documented in 8%. Significant findings affecting the TAVI procedure (category B) were found in 16% of patients. 

Conclusions: Pre-TAVI CTA detected non-valvular extra-vascular pathologies leading to procedure cancellation/postponement or procedure modification in 8% and 16%, respectively. Comprehensive CTA evaluation that acknowledges the importance of such findings is of major importance since it might alter the TAVI procedure or even render it inappropriate. 

 

Background: In criminal law, psychiatrists are consulted regarding the "insanity defense" and the defendant's competency to stand trial. Court-ordered hospital admissions for such evaluations are on the increase, creating a major burden on the health system.

Objectives: To assess, in a hospital setting, whether hospitalization of the defendant is necessary for conducting a psychiatric evaluation.

Methods: A 6 month prospective observational study exploring the phenomenon was conducted at the Beer Yaakov Mental Health Center. The psychiatrist was asked both at the initiation and again at the end of the assessment process whether the subject was competent to stand trial and responsible for his/her actions and if hospitalization was necessary in order to conduct the evaluation. 

Results: During the study period there were 112 admissions with a court request for a psychiatric evaluation. In 73 of the cases (65.2%) the evaluating psychiatrist believed there was no need for hospitalization. This assessment did not change by the end of the hospitalization in all cases. Employment and alcohol use were the only factors associated with a lower need for hospitalization (OR 0.24, 95%CI 0.07–0.77, and 0.34, 95%CI 0.13–0.90, respectively).

Conclusions: In the majority of cases, based on the evaluating psychiatrist's responses, the evaluation could have been conducted without need for hospitalization. The findings indicate that an outpatient unit designated to write court-requested psychiatric evaluations could significantly reduce the rates of hospital admissions for this purpose.

 

Background: Mycetoma is a chronic and destructive infection caused by either fungus or bacteria. Mycetoma has a characteristic clinical presentation of a triad of tumor-like swelling, draining sinuses, and macroscopic grains. Mycetoma infection is extremely rare in Israel; however, in view of the recent immigration from mycetoma-hyperendemic regions of Africa to Israel, physicians in Israel may encounter this infection.

Objectives: To present two cases of mycetoma caused by Madurella mycatomatis in immigrants from endemic regions in Sudan treated at our hospital, and review the current literature. 

Conclusions: Health care professionals in Israel should suspect mycetoma in patients from endemic countries who present with tumor-like swelling especially in the lower extremity. Health care workers should be able to recognize mycetoma and provide the optimal treatment before the lesion progresses to an advanced and disabling disease. 

 

Background: Atypical presentation of tuberculosis (TB) during pregnancy may cause diagnostic delay and adversely influence pregnancy outcome. 

Objectives: To examine the incidence and clinical and epidemiological features of TB during pregnancy and investigate infection control measures at delivery and during the postpartum period.

Methods: We retrospectively evaluated all reported cases of TB diagnosed during pregnancy to 6 months postpartum in Israel’s Northern Health District (2002–2012). 

Results: Active TB was detected in six patients; all were negative for human immunodeficiency virus (HIV). Two patients were diagnosed in the postpartum period, and four had pulmonary involvement. The average incidence during this period (3.9 per 100,000 pregnancies) was similar to that in the general population. Five patients were at high risk of contracting TB due to either recent immigration from a high-burden country or being in contact with another individual with active TB. Patients with pleuropulmonary involvement had prolonged cough and abnormal chest X-rays, without fever. Diagnosis was delayed for 3 to 7 months from symptom onset. Investigation of the newborn to rule out intrauterine infection was conducted in only one of four relevant cases. All patients were infected with organisms susceptible to all first-line drugs, and all were cured with standard therapy.

Conclusions: There was a considerable delay in the diagnosis of TB among pregnant women, and investigation of the newborn upon delivery to rule out TB infection was routinely omitted. Effective management of TB during pregnancy and the postpartum period requires a multidisciplinary approach including an obstetrician, pediatrician, TB specialist, and public health physician.

 

Abstract

Background: Findings of studies addressing outcomes of war-related famine in non-Jewish populations in Europe during the Second World War (WWII) confirmed an association between prenatal/early life exposure to hunger and adult obesity, diabetes, hypertension, cardiovascular heart disease and the metabolic syndrome. Fetal programming was suggested as the explanatory mechanism.

Objectives: To study the association between being born during WWII in Europe and physical long-term outcomes in child Holocaust survivors.   

Methods: We conducted a cross-sectional study on all Jewish Clalit Health Services (CHS) North District members born in 1940–1945 in Europe ('exposed', n=653) or in Israel to Europe-born parents ('non-exposed', n=433). Data on socio-demographic variables, medical diagnoses, medication procurement, laboratory tests and health services utilization were derived from the CHS computerized database and compared between the groups.

Results: The exposed were significantly more likely than the non-exposed to present with dyslipidemia (81% vs. 72%, respectively), hypertension (67% vs. 53%), diabetes mellitus (41% vs. 28%), vascular disease (18% vs. 9%) and the metabolic syndrome (17% vs. 9%). The exposed also made lower use of health services but used anti-depressive agents more often compared to the non-exposed. In multivariate analyses, being born during WWII remained an independent risk marker for hypertension (OR = 1.52), diabetes mellitus (OR = 1.60), vascular disease (OR = 1.99) and the metabolic syndrome (OR = 2.14).

Conclusions: The results of this cross-sectional study based on highly validated data identify a high risk group for chronic morbidity. A question regarding potential trans-generational effects that may impact the ‘second generation’ is also raised.

Background: Intra-articular corticosteroid injection (IACI), a common procedure in juvenile idiopathic arthritis, is usually associated with anxiety and pain. In a previous study, we concluded that nitrous oxide (NO₂) provides effective and safe sedation for such procedures. Following the introduction of medical clowns in our hospital, we added them as an integral part of the team performing IACI.

Objectives: To prospectively evaluate the effect of a medical clown on pain perception during intra-articular corticosteroid injection for juvenile idiopathic arthritis using NO₂ conscious sedation.

Methods: Patients scheduled for IACI first met and interacted with the medical clown. During the procedure, the rheumatologist and the medical clown worked in parallel to create distraction. NO₂ was administered. The patient, parent, physician, medical clown and nurse completed a visual analog scale (0–10) for pain. Change in heart rate ≥ 15% was recorded to evaluate physiologic response to pain and stress.

Results: A total of 46 procedures were performed in 32 children: 23 girls, 9 boys, with a mean age of 10.9 ± 3.6 years. The median visual analog scale pain score for the patients, parents, physicians, medical clown and nurses was 2, 2, 1, 1 and 1, respectively. Five patients had increased heart rate and experienced increased pain.

Conclusions: Active participation of a medical clown during IACI with nitrous oxide for juvenile idiopathic arthritis further decreases pain and stress and results in a positive patient experience.
