Most of the terminology in medicine originates from Greek or Latin, revealing the impact of the ancient Greeks on modern medicine. However, the literature on the etymology of Greek words used routinely in medical practice is sparse. We provide a short guide to the etymology and meaning of Greek words currently used in the field of hepatopancreatobiliary (HPB) anatomy and surgery. Focusing on HPB medical literature, the etymology and origin of Greek words including suffixes and prefixes are shown and analyzed. Thus, anatomy (anatomia) is a Greek word derived from the prefix ana- (on, upon) and the suffix -tomy from the verb temno meaning to cut. Surgery, however, is not a Greek word. The corresponding Greek word is chirourgiki derived from the cheir (hand) and the ergon (action, work) meaning the action made by hands. Understanding the root of Greek terminology leads to an accurate, precise and comprehensive scientific medical language, reflecting the need for a universal medical language as a standardized means of communication within the health care sector. 

 

Background: Isolation of methicillin-resistant Staphylococcus aureus (MRSA) in healthy individuals is not common in Israel. In our hospital, about 30% of MRSA isolates were SCCmec types IV and V.

Objectives: To identify the demographic and clinical characteristics of patients carrying MRSA SCCmec type IV or V, and to compare them with each other and with those of patients with SCCmec types I-III.

Methods: We conducted a case-control study that included 501 patients from whom MRSA was isolated: 254 with SCCmec type I, II, or III, and 243 isolates from SCCmec types IV or V. 

Results: MRSA was isolated from surveillance cultures in 75% of patients and from a clinical site in 25%. The majority of our study population was elderly, from nursing homes, and with extensive exposure to health care. First, we compared characteristics of patients identified through screening. Statistically significant predictors of SCCmec V vs. IV were Arab ethnicity (OR 7.44, 95%CI 1.5–37.9) and hospitalization in the year prior to study inclusion (OR 5.7, 95%CI 1.9–16.9). No differences were found between patients with SCCmec types I-III and patients with SCCmec type IV or V. Analysis of the subset of patients who had clinical cultures yielded similar results. 

Conclusions: SCCmec types IV and V were common in the hospital setting although rare in the community. It seems that in Israel, SCCmec IV and V are predominantly health care-associated MRSA. 

 

Breast magnetic resonance imaging (MRI) has an important role in the detection and diagnosis of breast cancer. Suspicious findings on MRI are further evaluated with ultrasound. This case series illustrates the use of automated breast volumetric ultrasound (ABVS) as a tool for second-look ultrasound (SLUS) following MRI. Seven women underwent breast MRI with findings necessitating SLUS. ABVS was used for second look and all MRI lesions were detected. Four cancers, one fibroadenoma and two benign lesions, were diagnosed. This case series shows that ABVS can be used as a tool for SLUS following MRI and in some cases is superior to hand-held ultrasound.

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: Admission glucose levels correlate with clinical outcome in patients with type 2 diabetes mellitus (T2DM) hospitalized in general medicine wards. 

Objective: To investigate whether in-hospital hyperglycemia alone and after adjustment for age, gender and lipidemia correlates with in- and out-of-hospital mortality.

Methods: Capillary glucose, serum lipids and diagnoses at discharge among patients with T2DM hospitalized in the general medical wards of our hospital were documented. Correlation with in- and out-of-hospital mortality was determined through uni- and multivariate analyses. 

Results: Of the 4607 patients included in the study 22% died while hospitalized. From a median of five capillary glucose tests obtained per patient, average capillary glucose level was significantly lower in those who survived than in those who died (174 ± 64 vs. 180 ± 65 mg/dl, P = 0.005). Overall, blood cholesterol was higher in those who survived than in those who died (P < 0.001). Multivariate analysis, however, including age, gender, lipidemia and glycemia, showed that only age and male gender correlated with mortality.

Conclusions: Hyperglycemia was associated with increased in- and out-of-hospital mortality on univariate analysis. However, it was not an independent risk factor when corrected for age, gender and hyperlipidemia. 

 

Background: The efficacy of video-assisted thoracoscopic surgery lobectomy in patients with previous coronary artery bypass grafting (CABG) surgery is controversial.

Objectives: To investigate whether skeletonized left internal mammary artery (LIMA) mobilization contributes to the development of severe adhesions, which will affect what type of lung surgery (open or closed procedure) will be required in the future.

Methods: Eight patients (mean age 73.9 years) with previous CABG surgery using a LIMA to left anterior descending (LAD) graft underwent left-sided lobectomy for operable non-small cell lung carcinoma. 

Results: The lobectomy by thoracotomy rate was 62.5% (5 patients), generally in patients with tumors in the left upper lobe or in patients post-neoadjuvant chemotherapy, while the video-assisted thoracic surgery lobectomy rate was 37.5% (3 patients). Mean hospital stay was 8.3 days. There was no mortality or major morbidity, apart from six minor complications in four patients (50%) (air leak, atrial fibrillation, atelectasis, pneumonia). 

Conclusions: Patients with operable non-small cell lung carcinoma following CABG surgery who need left upper lobe resection do not benefit from the video-assisted thoracoscopic surgery technique due to significant adhesions between the LIMA to LAD graft and the lung. The method of preserving a small portion of the lung on the LIMA to LAD graft may help during left upper lobe resections. Adhesions in the left pleural space after LIMA mobilization appear to generally minimally affect left lower lobe video-assisted thoracoscopic surgery.

 

Abstract

Background: Only a few studies have compared the accuracy of magnetic resonance enterography (MRE) and computed tomography enterography (CTE) in the diagnosis of Crohn's disease and its complications.

Objectives: To compare the sensitivity of MRE and CTE analysis in their ability to detect, sign-by-sign, 10 classical imaging signs of Crohn's disease.

Methods: The study group comprised 42 biopsy-proven Crohn's disease patients who underwent both CTE and MRE within an average period of 6 weeks. Agreement between the two modalities in detecting the 10 most significant radiological signs of CD was evaluated using the Kappa index. The sensitivity of MRE and CTE was calculated using a standard of reference composed of all the findings seen by CTE and/or MRE. We analyzed MRE and CTE sensitivity separately in two groups, according to the time interval between the examinations.

Results: Agreement between CTE and MRE was more than 70% in 8 of the 10 signs: mural thickening, phlegmon, stenosis, skip lesions, mucosal stratification, fistula, abscess, and creeping fat. The Kappa level of agreement values for CTE versus MRE varied between substantial for phlegmon and skip lesions; moderate for fistula, creeping fat, abscess and mural thickening; and fair for stenosis and dilatation. CTE detected more findings than MRE, except for creeping fat and fistula. There was no significant difference in the sensitivity of CTE and MRE in the two groups defined by the time interval (time < 1.5 and time > 1.5 months) except for detection of dilatation.

Conclusions: Almost all imaging signs of Crohn's disease were detected equally well by both modalities regardless of the time interval between examinations. We therefore consider MRE to be reliable for imaging and follow-up in patients with Crohn's disease who may need recurrent imaging.

Abstract

Background: Laryngeal cleft (LC) is a rare congenital anomaly manifesting in a variety of symptoms including swallowing disorders and aspirations, dyspnea, stridor and hoarseness. The mild forms (types I-II) may be underdiagnosed, leading to protracted symptomatology and morbidity. 

Objectives: To evaluate the diagnostic process, clinical course, management and outcome in children with type I-II laryngeal clefts.

Methods: We conducted a retrospective case analysis for the years 2005–2012 in a tertiary referral center.

Results: Seven children were reviewed: five boys and two girls, aged from birth to 5 years. The most common presenting symptoms were cough, aspirations and pneumonia. Evaluation procedures included fiber-optic laryngoscopy (FOL), direct laryngoscopy (DL) and videofluoroscopy. Other pathologies were seen in three children. Six children underwent successful endoscopic surgery and one child was treated conservatively. The postoperative clinical course was uneventful in most of the cases.

Conclusions: Types I-II LC should be considered in the differential diagnosis of children presenting with protracted cough and aspirations. DL is crucial for establishing the diagnosis. Endoscopic surgery is safe and should be applied promptly when conservative measures fail. 

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.
