Objectives: To measure the tumor-to-breast volume ratio using MRI in order to assess whether there is a correlation between this ratio and the type of surgery selected (breast-conserving or mastectomy).

Methods: The volumes of the tumor and the breast and the tumor-to-breast volume ratio were retrospectively calculated using preoperative breast MRI in 76 patients who underwent breast-conserving surgery or mastectomy.

Results: Breast-conserving surgery (lumpectomy) was performed in 64 patients and mastectomy in 12. The average tumor-to-breast volume ratio was 0.06 (6%) in the lumpectomy group and 0.30 (30%) in the mastectomy group (P < 0.0001).

Conclusion: The tumor-to-breast volume ratio correlated with the type of surgery. As measured on MRI, this ratio is an accurate means of determining the type of surgery best suited for a given patient. It is recommended that MRI-determined tumor-to-breast volume ratio become part of the surgical planning protocol for patients diagnosed with breast cancer.

Objectives: To examine the quality and accuracy of diagnoses recorded in the ED in order to appraise its potential utility as a guage of the population's medical needs.

Methods: Using the Delphi process, a preliminary list of health indicators generated by an expert focus group was transformed into a query to the Ministry of Health's database. In parallel, medical charts were reviewed in four hospitals to compare the handwritten diagnosis in the medical record with that recorded on the standard diagnosis "pick list" coding sheet. Quantity and quality of coding were assessed using explicit criteria.

Results: During 2010 a total of 17,761 charts were reviewed; diagnoses were not coded in 42%. The accuracy of existing coding was excellent (mismatch 1%–5%). Database query (2,670,300 visits to 28 hospitals in 2009) demonstrated potential benefits of these data as indicators of regional health needs.

Conclusions: The findings suggest that an increase in the provision of community care may reduce ED attendance. Information on ED visits can be used to support health care planning. A "pick list" form with common diagnoses can facilitate quality recording of diagnoses in a busy ED, profiling the population’s health needs in order to optimize care. Better compliance with the directive to code diagnosis is desired.

Objectives: To prove the safety and efficacy of LSG surgery in an adolescent population

Methods: Data were prospectively collected regarding adolescent patients undergoing LSG. All patients underwent pre- and postoperative medical and professional evaluation by a multidisciplinary team.

Results: Between the years 2006 and 2011, 32 adolescents underwent LSG in our center (20 females and 12 males). Mean age was 16.75 years (range 14–18 years), mean weight was 121.88 kg (83–178 kg), and mean body mass index 43.23 (35–54). Thirty-four comorbid conditions were identified. In all the patients LSG was the primary bariatric procedure. Mean operative time was 60 minutes (range 45–80 min). There were two complications (6.25%): an early staple line leak and a late acute cholecystitis. There was no mortality. Mean percent excess weight loss at 1, 3, 6, 9,12, 24, 36, 48, and 60 months post-surgery was 27.9%, 41.1%, 62.6%, 79.2%, 81.7% , 71%, 75%, 102.9% and 101.6%, respectively. Comorbidities were completely resolved or ameliorated within 1 year following surgery in 82.4% and 17.6%, respectively.

Conclusions: LSG is feasible and safe in morbidly obese adolescents, achieving efficient weight loss and impressive resolution of comorbidities. Further studies are required to evaluate the long-term results of this procedure, as well as its place among other bariatric options. 

Objectives: To assess the relationship between sleep deprivation, key metabolic markers, and professional performance in medical residents.

Methods: We compared 35 residents working the in-house night shift with 35 senior year medical students in a cross-sectional cohort study. The Epworth Sleepiness Scale (ESS) questionnaire was administered and blood tests for complete blood count (CBC), blood chemistry panel, lipid profile and C-reactive protein (CRP) were obtained from all participants.

Results: Medical students and medical residents were comparable demographically except for age, weekly working hours, reported weight gain, and physical activity. The ESS questionnaires indicated a significantly higher and abnormal mean score and higher risk of falling asleep during five of eight daily activities among medical residents as compared with medical students. Medical residents had lower high density lipoprotein levels, a trend towards higher triglyceride levels and higher monocyte count than did medical students. CRP levels and other laboratory tests were normal and similar in both groups. Among the medical residents, 5 (15%) were involved in a car accident during residency, and 63% and 49% reported low professional performance and judgment levels after the night shift, respectively.

Conclusions: Medical residency service was associated with increased sleepiness, deleterious lifestyle changes, poorer lipid profile, mild CBC changes, and reduced professional performance and judgment after working the night shift. However, no significant changes were observed in CRP or in blood chemistry panel. Larger prospective cohort studies are warranted to evaluate the dynamics in sleepiness and metabolic factors over time.

Objectives: To evaluate if fetal reduction of triplets to twins improves outcome.

Methods: We analyzed the outcome of 80 triplet gestations cared for at Rambam Health Care Campus in the last decade; 34 families decided to continue the pregnancy as triplets and 46 opted for MFPR to twins.

Results: The mean gestational age at delivery was 32.3 weeks for triplets and 35.6 weeks for twins after MFPR. Severe prematurity (delivery before 32 gestational weeks) was experienced in 37.5% of triplets and in 7% of twins. Consequently, the rate of severe neonatal morbidity (respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular hemorrhage) and of neonatal death was significantly higher in unreduced triplets, as was the length of hospitalization in the neonatal intensive care unit (31.4 vs. 15.7, respectively). Overall, the likelihood of a family with triplets to take home all three neonates was 80%; the likelihood to take home three healthy babies was 71.5%.

Conclusions: MFPR reduces the risk of severe prematurity and the neonatal morbidity of triplets. A secondary benefit is the reduction of cost of care per survivor. Our results indicate that MFPR should be offered in triplet gestations.
