Circulating Cell-free DNA in Patients With Acute Biliary Pancreatitis: Association With Disease Markers and Prolonged Hospitalization Time-A Prospective Cohort Study.

OBJECTIVE: To evaluate cfDNA as an indicator of pancreatitis severity. BACKGROUND: Acute pancreatitis severity scores have limited proficiency, and are complex and challenging to use clinically. Elevation of circulating cfDNA concentration has been shown to be associated with hospital length of stay (LOS) and mortality. METHODS: In a prospective study, cfDNA concentration was measured by a simple fluorometric test, at admission and for 2 consecutive days, in patients with acute biliary pancreatitis (ABP). Ranson and APACHE II scores were used as measures of pancreatitis severity. Hospital LOS and mortality were used as outcome measures. RESULTS: Seventy-eight patients were included. Patients with severe disease according to Ranson's Criteria (n = 24) had elevated median admission cfDNA compared to patients with mild disease (n = 54, 2252ng/ml vs 1228 ng/ml, P < 0.05 ). Admission cfDNA levels correlated with Ranson and APACHE II scores and markers of bile duct obstruction. LOS did not differ between patients with mild and severe disease according to Ranson and APACHE II scores. Patients with cfDNA at 24 hours concentrations above the cutoff value of healthy patients (>850 ng/ml) had a significantly longer LOS compared to those with normal cfDNA levels ( P < 0.001 ). CONCLUSIONS: cfDNA, measured by a rapid simple assay, proved a valuable early marker of severity in ABP with clear advantages for prediction of LOS over Ranson and APACHE II. Measurement of cfDNA has the potential to be an effective practical approach to predict the course of ABP and should be further evaluated in larger trials.

[LANDMARKS IN THE MEDICAL HISTORY OF ISRAEL - IS IT TRULY INTERWEAVING WITHIN THE ISRAELI POSTAL STAMP].

INTRODUCTION: Issuing postal stamps is the main sign of a nation's independence. The first stamps series of Israel were issued a mere two days after the declaration of Israel's independence. Since then, almost 1750 postal stamps were issued as a single unit or different stamps series. These stamps delineate and emphasize innovations, military and civilian technological developments, the high holidays and nature as well as respecting important national figures and holidays. The aim of our historical search of philately (stamps collection) through the 20th century till today was to find out the frequency of the interweaving of medicine, medical developments and the tribute to outstanding figures, in all medical fields, and their contribution during peace and war periods in Israeli stamps. The thorough research study revealed only 16 stamps that were issued perpetuating medical disciplines - 0.9% of all stamps. Despite their national and worldwide significance there were no stamps commemorating many medical and surgical fields. I did not find reminiscence of our military medical developments that have become a competent authority for numerous armies all over the world. Organ transplantation, surgical innovations and the large group of women physicians and surgeons that took leadership in several medical fields have no presence in our postal stamps. Nowadays, philately has lost its importance as a financial value for the prompt e-mails. I believe philately should be encouraged to issue current postal stamps dedicated to "blue and white" medicine, a thing that is even more adequate these days in which all the medical community was enlisted to battle the new corona pandemic.

[SURGICAL PALLIATION FOR PANCREATIC CANCER].

INTRODUCTION: Pancreatic cancer (PC) is the 11th most common malignancy worldwide, however, entailing a mortality in excess of 90% within 5 years from diagnosis, it is the 4th most fatal malignant disease. PC is commonly diagnosed at an advanced stage, in which curative resection is no longer possible. Even patients who present with potentially curable disease will have upward of 30% recurrence of their disease within the first year. Thus, palliative therapy has paramount importance in patient management. The purpose of palliative care in these patients is to relieve symptoms and improve quality of life. This article reviews the current state of invasive palliation techniques for advanced PC, which are commonly directed towards three main symptoms: gastric/duodenal obstruction, obstructive jaundice, and epigastric pain. We describe the pros and cons of the different techniques, along with current front-line technology advancements. Endoscopic stenting is highly efficient in patients with gastric/duodenal obstruction or obstructive jaundice, with a generally low complication rate, short hospitalization and sustained quality of life. Bypass surgery should be considered in patients with a long-anticipated life expectancy, following higher rates of long-term stent failure, or when endoscopic stent procedure is not possible or has failed. When treating abdominal pain, celiac plexus neurolysis is considered as the first-line treatment. Pancreatic cancer is a complex and commonly lethal disease strongly affecting patient quality of life. It is important to consider the specific patient's personal characteristics and disease status when planning their palliative care.

Low Incidence of Postoperative Leaks When Using Small-Diameter Calibrated Bougies During Laparoscopic Sleeve Gastrectomy: A Retrospective Cohort Study.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a well-established bariatric procedure. A staple line leak is a recognized complication of LSG. Bougie size has been suggested to impact leak rates. In this study, we evaluate the impact of using 32-34F bougie sizes with LSG on early postoperative outcomes including staple line leaks within our practice. METHODS: This is a retrospective cohort analysis of a prospectively maintained database of all LSG procedures performed between January 2012 and December 2018 at a single medical center. Data collected and analyzed included bougie size, postoperative leak rate, need for re-operation, 12-month excess weight loss, and 30-day morbidity and mortality. RESULTS: During the study period, 3153 patients underwent LSG, of whom 1977 (62.7%) were female. Mean age and body mass index (BMI) were 42.9 ± 12.2 years (range 15-76 years) and 42.4 ± 5.2 kg/m2 (range 27-73), respectively. No intraoperative complications or mortality occurred. There was one case of perioperative mortality due to bleeding (0.03%). Early postoperative adverse events occurred in 131 patients (4.1%): 17 leaks (0.5%), 75 bleeds (2.4%), and 39 (1.2%) other. CONCLUSION: The use of smaller-sized (32-34F) bougies had no impact on staple line leaks in the hands of experienced bariatric surgeons at a high-volume center.

Pediatric Carbon Monoxide Poisoning in Southern Israel: A Cross-Sectional Study.

OBJECTIVES: This study aimed to describe the epidemiology and clinical burden of unintended carbon monoxide (CO) poisoning among children in the Negev region of southern Israel. METHODS: This was a cross-sectional retrospective study of CO poisoning patients admitted to Soroka University Medical Center in 2011 through 2015. RESULTS: Overall, 43 cases of CO poisoning were recorded among children younger than 18 years. Five patients died, all upon admission. Poisoning due to smoke "per se" and due to CO emitted from heating devices were responsible for 28 (65.1%) and 14 (32.6%) cases, respectively. Eight (18.6%) patients suffered from convulsions, and 13 (43.3%) of 30 evaluable patients complained of headaches. Twenty-two (51.2%) were found unconscious in the field, and 7 (16.3%) were unconscious at examination at the emergency department. The average carboxyhemoglobin level on admission was 10.5% ± 10.4% (level ranging from 0.1% to 46.2%). Treatment included oxygen in 34 patients (79%) and hyperbaric oxygen therapy in 8 patients (19%). No differences were found between Bedouin and Jewish children in sex, age, residence area, source of CO poisoning, symptoms severity, and need for hyperbaric oxygen therapy. More patients with exposure to water heating devices were older than 4 years, lived in villages, and were diagnosed as having loss of consciousness in the field compared with those exposed to smoke inhalation. CONCLUSIONS: Carbon monoxide poisoning in children is frequent in southern Israel. Education about prevention, implementation of safer standards for home heating systems, and government supervision are required management strategies to decrease the CO poisoning incidence in southern Israel.

[PEDIATRIC ANIMAL-RELATED INJURIES IN THE JEWISH AND ARAB POPULATION IN SOUTHERN ISRAEL].

INTRODUCTION: Annually in the US, about 2 million patients who are animal-related casualties go to the Emergency Medicine Department (ER), which accounts for 0.5-1.5% of the ER visits; 25% of these casualties are children. Similar numbers are also seen in Europe and the UK. In a single-center study in Israel, it was found that the percentage of ER visits for animal injuries was about 2.1%. Soroka University Hospital is the only Level I trauma center in the Negev, serving a population of over 1,250,000, and as such it treats about 175,000 ER visits each year, of which about 27% are pediatric visits. The population treated in our hospital is diverse in terms of socioeconomic origin and status, and includes Jewish patients mainly situated in urban settlements and Arab-Bedouin population living in familiar and unfamiliar villages (the Bedouin diaspora). In light of this, in the present study, we have tried to investigate animal injuries in children, emphasizing scorpion bites which are common in our area. METHODS: We retrospectively reviewed the medical records of all children aged 0-17 years during an 18-month study period - from January 2009 until the end of June 2010 - to identify children who have been referred to the ER at the Soroka Hospital due to animal injury. Demographics, characteristics of the injury, incidence times and referral to treatment, and data on the course of assessment and treatment of the injury and hospitalization were recorded. Data was typed and processed using Microsoft Excel 2007 software and we used SPSS 23.0 for Windows for the statistical analysis. RESULTS: A total of 729 pediatric injuries caused by animals were reported, which accounted for about 1% of the total number of children's visits to the pediatric ER during the study period. Twenty-six cases were omitted because they did not meet the inclusion criteria in the study. Of the remaining 703 referrals, 66.1% of the patients were boys, the peak age was in the 6-8-year age group (26%); 44.1% lived in a Jewish settlement, 31.2% in an unrecognized Arab-Bedouin settlement and 24% in a recognized Arab-Bedouin settlement. In both forms of Bedouin settlements, the most frequent injuries were dog bites n = 166, (23.60%), yellow scorpion bites = 163 (23.2%) and black scorpion bites n = 44 (6.25%); 97 of the children were admitted (13.8%), of whom 44 were admitted to the ICU, with 84.1% of those admitted to the intensive care unit (ICU) were treated due to yellow scorpion injury. The 2-5-year age group was the most prevalent among inpatients, accounting for 32. DISCUSSION: Pediatric animal injuries are a common cause of ER visits and even hospitalization. A relatively high percentage of hospitalizations were in the ICU. The most common cause of animal injury seen in our cohort was dog bites, but yellow scorpion bites resulted in most hospitalizations, especially in the pediatric ICU. The incidence of yellow scorpion injuries was significantly higher in the Arab-Bedouin population and even more so in those living in unrecognized settlements, and 87% of the pediatric hospitalizations were seen in Arabic-Bedouin children. Animal-related injuries are a serious health problem in the Arab-Bedouin population and in the unrecognized villages in particular, and there is room to emphasize the prevention of these injuries in this impoverished sector.

Clinical and Laboratory Findings in Jewish and Bedouin Patients in Southern Israel Who Were Diagnosed with Factor VII Deficiency.

BACKGROUND: Congenital factor VII deficiency is a rare recessive autosomal bleeding disorder with a wide spectrum of clinical manifestations. OBJECTIVES: To compare the clinical and laboratory findings in Jewish and Bedouin patients with factor VII deficiency. METHODS: The clinical and laboratory findings of patients with factor VII deficiency treated at Soroka Medical Center, a tertiary hospital in Israel, from 2005 to 2015 were analyzed regarding blood factor levels, illness severity, treatment administration, and disease outcome. RESULTS: Seventy-eight patients were enrolled (1:13,000 of the population in southern Israel) of whom 26 were diagnosed with severe factor VII deficiency (1:40,000). Sixty (76.9%) patients were Jewish and 18 (23.1%) were Bedouin. In univariable analysis, Bedouin patients exhibited a more severe illness, with significantly higher complication and fatality rates, and required more preventive treatment than the Jewish patients. CONCLUSIONS: The prevalence of congenital factor VII deficiency (including severe deficiency) in the Jewish and Bedouin populations of southern Israel is higher than previously reported. The clinical spectrum of the disease was found to be more severe in the Bedouin population.

[IS THERE STILL A PLACE TO USE ERYTHROCYTE SEDIMENTATION RATE IN THE 21ST CENTURY?]

INTRODUCTION: Erythrocyte sedimentation rate (ESR) is a simple test that is not without limitations but is still widely used. Dysfunction is used as a diagnostic test on the one hand and as a follow-up test on the other, where many physicians attribute normal results of this test to the absence of disease. Therefore, the question remains: Is there still room for continued ESR in the 21st century? And are there other tests with higher sensitivity and specificity that can replace the ESR? The purpose of the current review is to acquaint the reader with this test, its advantages and limitations, and to expand the scope of alternative tests and their effectiveness in comparison to ESR. It seems to us that the development of technology and research has strongly discouraged the use of ESR, but there are still quite a few instances where this test is still cost-effective. In most cases, especially during the diagnosis of life-threatening diseases, other tests are needed, or there is a need for a combination of the ESR with additional tests.

Immediate Effects of Transcranial Direct Current Stimulation on Obsession-Induced Anxiety in Refractory Obsessive-Compulsive Disorder: A Pilot Study.

OBJECTIVE: Studies have shown that transcranial direct current stimulation (tDCS) has immediate effects on brain activity. The aim of this study was to investigate the potential use of tDCS to regulate obsession-induced anxiety immediately after symptom provocation in patients with refractory obsessive-compulsive disorder (OCD). METHODS: Twelve patients with refractory OCD received cathode, anode, and sham transcranial direct current stimulation over the medial prefrontal cortex conjugant to pharmacological treatment in a crossover design. Before and after the DC stimulation, patients graded the intensity of their anxiety after a short exposure to a provoking stimulus using the visual analogue scale. Clinical questionnaires assessing symptoms severity were also applied before each stimulation mode. RESULTS: We found a statistically significant decrease in the severity of the obsession-induced anxiety (decreased visual analogue scale) as a result of cathode tDCS in comparison with the anode and sham stimulation. Reduction in obsession-induced anxiety was consistent, yet short lasting, and was independent of symptom severity. CONCLUSIONS: Cathode tDCS could be potentially used to regulate obsession-induced anxiety in refractory OCD patients. Further studies are warranted to confirm our results as well as to determine whether tDCS can achieve prolonged benefits in OCD and be of aid in behavioral treatments based on exposure.

Comparison of the Long-Term Oncological Outcomes of Stent as a Bridge to Surgery and Surgery Alone in Malignant Colonic Obstruction.

BACKGROUND: Self-expanding metallic stents (SEMS) insertion is an alternative to emergency surgery in malignant colonic obstruction. However, the long-term oncological outcome of stents as a bridge to surgery is limited and controversial. OBJECTIVES: To determine the long-term oncological outcome of stents as a bridge to surgery. METHODS: Data of patients who underwent emergency surgery and endoscopic stent insertion as a bridge to surgery due to obstructing colon cancer at Soroka Medical Center during a 14 year period were collected retrospectively. Preoperative data, tumor staging, and oncological outcomes in terms of local recurrence, metastatic spread, and overall survival of the patients were compared. RESULTS: Sixty-four patients (56% female, mean age 72 years) were included in the study: 43 (67%) following emergency surgery, 21 stent inserted prior to surgery. A stent was inserted within 24-48 hours of hospital admission. The mean time between SEMS insertion and surgery was 15 days (range 0-30). Most of the patients had stage II (41%) and stage III (34%) colonic cancer. There was no difference in tumor staging and localization between groups. There was no significant difference in disease recurrence between SEMS and surgery groups, 24% and 32%, respectively. Disease-free survival rates were similar between the SEMS group (23.8%) and surgery group (22%). Four year and overall survival rates were 52.4% vs. 47.6%, 33.3% vs. 39.5%, respectively. CONCLUSIONS: SEMS as a bridge to surgery in patients with obstructing colon cancer provide an equivalent long-term oncological outcome to surgery alone.

[DEMOGRAPHIC AND ANATOMIC CHARACTERISTICS AND SURGERY RESULTS IN CHILDREN WHO WERE TREATED IN SOROKA FOR CRANIOSYNOSTOSIS].

BACKGROUND: Craniosynostosis, the premature fusion of one or more of the cranial sutures, can occur as a part of a syndrome or as an isolated deformity. When not treated properly it may have major physical and social implications. STUDY HYPOTHESIS: We assumed that our center's results are similar to those reported in the literature, in terms of gender and anatomic characteristics, and different in terms of the number of syndromic cases. We also assume that only a few patients needed a second surgery and that this medical problem effects quality of life in term of cognitive impairment and aesthetic results. METHODS: A retrospective chart review was conducted of patients who were treated for craniosynostosis in Soroka University Medical Center between the years 1991-2005. RESULTS: A total of 63 patients were treated in Soroka during those years: 30 (47.6%) were females and 33 (50.8%) were males; 27 (42.9%) had coronal synostosis, 20 (31.8%) had sagital synostosis, 10 (15.8%) had metopic synostosis, 5 (7.9%) had lambdoid synostosis. A total of 5 (7.9%) cases were syndromic and the rest were isolated; 6 patients (9.5%) needed a second surgery for correction of the defect; 8 out of 30 patients (26.7%) 6 years or older at the present time suffer from attention deficit disorder. Parents' satisfaction from aesthetic results on a scale of 1-5 was 4.77 with SD of 0.504, while the doctors' score was 3.93 with SD 0.980 (p = 0.01). CONCLUSIONS: Craniosynostosis is a complex surgical problem, however with prompt treatment it may attain high levels of satisfaction among parents and patients. We found high rates 26.7% vs 10% (in the general population) of ADD in children affected by the disease.

Athlete's heart in Israel: fact or fiction.

BACKGROUND: The effects of exercise training on cardiac structure and function have been thoroughly investigated in athletes from sport-developed nations; few data are available on sportsmen from sport-developing countries. OBJECTIVES: To assess the incidence and magnitude of the "athlete heart" phenomenon in an elite group of Israeli cyclists. METHODS: An echocardiography study was performed in 56 cyclists (49 males, mean age 38 +/- 10 years, weekly average training 13.1 +/- 5.9 hours); 96 sedentary subjects served as a control group. RESULTS: There were significant differences in left ventricular end-diastolic diameter (LVEDD) between cyclists and the control group (48 +/- 4.7 mm versus 45 +/- 4.1 mm respectively, P < 0.001), as well as in inter-ventricular septum (IVS) thickness (9.9 +/- 1.2 versus 8.9 +/- 1.2 mm, P < 0.001) and LV mass index (LVMI) (79 +/- 16 versus 68 +/- 13 g/m(2), P < 0.001). In 5% of the cyclists LVEDD exceeded the upper normal limit of 56 mm. In 7% of the cyclists IVS thickness exceeded the upper normal limit of 11 mm. LV hypertrophy defined as LVMI > or = 134 g/m(2) was absent in the entire cyclist group. CONCLUSIONS: Endurance sport activity in well-trained Israeli sportsmen results in a modest increment in LV dimensions and LV mass. LV dilatation and wall thickness above values compatible with primary cardiac disease are rare. These results highlight that in Israeli athletes any abnormal echocardiographic value must be thoroughly investigated and not simply assumed to be a consequence of sport activities.

[Sexual behavior characteristics of clients attending the Israel AIDS Task Force anonymous clinic in Tel Aviv].

UNLABELLED: Until now, research on sexual behavior and HIV in Israel has been carried out mainly on the general population, and focused primarily on defining populations at risk, without adequate consideration given to the reasons bringing these populations to be tested, and their specific sexual behaviors. In Israel, one can choose whether to take an HIV test in confidential centers (giving one's name under medical confidentiality) or in anonymous centers (Israel AIDS Task Force in Tel Aviv and Beer Sheva, Levinsky Clinic in Tel Aviv and Haparsim Clinic in Haifa]. At least 21% of the clients of the anonymous testing centers in Israel belong to a high risk population in contrast to 2.6% in confidential clinics, and so, in this study, we hypothesize that characterization of sexual behavior patterns in anonymous testing centers might enable us to better characterize sexual behavior patterns in high risk populations. METHODS: In this cross-sectional study, we used questionnaires distributed in the clinics by the Israel AIDS Task Force in order to characterize their clinic's clients. The questionnaires were completed by the Israel AIDS Task Force consultants during the consultation period at which the anonymous test was performed. Data collected included: gender, age, testing history, specific sexual behaviors and reasons for applying for the current test. RESULTS: A total of 926 questionnaires were collected; 29.9% of them were of female patients. The average age was 29.47 years (1±8.66]; 21.3% of the clients were men who have sex with men [MSM]; only 2.3% of the clients belonged to other high risk populations. In all groups, the majority of the patients reported high risk sexual behavior (any sexual contact without a condom) and the average age for the first test was much higher than the average age of first sexual intercourse common in Israel. Women reported more participation in unprotected vaginal intercourse than heterosexual men, and a substantial part of MSM reported performing unprotected anal intercourse. More heterosexuals than MSM stated a new relationship as a reason for applying for the test, and more MSM than heterosexuals reported arriving for a routine check-up. CONCLUSIONS: There is a need for comprehensive programs encouraging testing for HIV in all age groups, focusing on Sthe ages 18-25 years, and encouraging the use of a condom as a preventive measure in all populations, especially women. We feel it is essential to emphasize the need for educational programs tailored for each sub-population's psychosocial characteristics and specific issues.

The impact of preoperative breast MRI on the therapeutic management of breast cancer patients.

BACKGROUND: The role of preoperative breast MRI to evaluate the extent of disease in breast cancer patients is considered controversial. We aimed at assessing the effect of breast MRI on the management of newly diagnosed breast cancer. MATERIALS: A retrospective review of 202 consecutively seen patients who were newly diagnosed with breast cancer and who underwent preoperative breast MRIs at Assuta Ashdod between June 1, 2017, and June 1, 2020. Data included discovering suspicious lesions by conventional imaging, MRI findings, and surgical pathology results. This was analyzed to determine whether the MRI changed the management and whether it had a justified or unjustified effect on the treatment. RESULTS: The mean age was 54.51 (standard deviation, 11.34 years). Breast MRI revealed additional findings in 56 % of patients and modified therapeutic management in 32 % of the cases evaluated, having a justified effect in 87.6 %. Patients with changed management had a statistically significantly higher mastectomy rate (36 %) than those who did not (14 %). No statistically significant association was found between independent variables such as breast density, tumor location on the breast, type of tumor, patient's demographic information, etc. And whether MRI findings changed the initial treatment plan. CONCLUSIONS: MRI played an essential role in the preoperative staging of breast cancer in our study, modifying therapeutic planning in approximately one-third of the cases and having a justified effect on most of them. We, therefore, support preoperative breast MRI in newly diagnosed breast cancer patients.

Gender Comparisons of Surgical Outcomes in Patients Undergoing One Anastomosis Gastric Bypass (OAGB): a Historical Cohort Study.

INTRODUCTION AND PURPOSE: Clinical trials in the field of bariatrics have frequently been gender imbalanced, with males representing only 20% of examinees. Long-term gender-oriented results in one anastomosis gastric bypass (OAGB), and specifically quality of life (QOL) parameters, have not been addressed sufficiently. A better understanding of gender's effect on OAGB outcomes can play an important role in selecting the appropriate bariatric surgery for patients. Our study was aimed at examining mid-term gender-associated outcome of OAGB, including the effect on QOL. MATERIALS AND METHODS: A retrospective cohort study of patients who underwent OAGB at surgical ward A, SUMC, Israel, between 2015 and 2020. Demographics, body mass index (BMI), and comorbidities were extracted from the national medical records system. Follow-up quality of life (QOL) and weight parameters were supplemented via telephone questionnaires, using the Bariatric Analysis and Reporting Outcome System (BAROS). RESULTS: A total of 152 patients were included; of these, 51 (33.6%) were males, with an average follow-up period of 4.1 (± 1.3) years post-surgery. Basic demographics showed no significant pre- or post-surgery differences between males and females, except for pre-op weight (which as expected was higher for males). Males had a higher overall BAROS score than females (3.8 ± 2.1 vs. 2.6 ± 2.1, p < 0.001). CONCLUSIONS: OAGB surgery results in better outcomes for male than for female patients as measured by the BAROS, despite a similar BMI reduction, and with no difference in complications. Gender-specific outcomes are one of the variables that one should be aware of in optimizing patient selection and pre-operative patient counseling.

Banded One-Anastomosis Gastric Bypass (BOAGB) for Patients Living with Obesity and Extreme Obesity: A Single Institution's Experience.

BACKGROUND: The prevalence of patients suffering from extreme obesity (body mass index (BMI) ≥ 50) has significantly increased over the past three decades, surpassing the rise in the general population of overweight patients. Weight loss outcomes after bariatric surgery in patients suffering from extreme obesity are less favorable, with a higher incidence of weight regain. Variations of existing bariatric procedures have been proposed to address this issue. One such variation is adding a gastric band to limit the expansion of the newly created pouch. Limited data exist regarding the effectiveness of this procedure, called the banded one-anastomosis gastric bypass (BOAGB) procedure, compared to other bariatric procedures. METHOD: In this retrospective study, we compared all patients who underwent the BOAGB procedure at the Bariatric Surgery Unit in our Medical Center with a postoperative follow-up of at least 1 year with patients who underwent a one-anastomosis gastric bypass (OAGB) or sleeve gastrectomy (SG) procedures. Data collected included demographics, comorbidities, surgical outcomes, complications, and postoperative quality-of-life assessments. RESULTS: One hundred eleven patients were enlisted to our study during the relevant study period-24 patients underwent the BOAGB procedure, 43 underwent OAGB, and 44 underwent a SG. Lost to follow-up beyond 30 days was 9% (at 1-year post-surgery, we were able to establish contact with 101 patients). The pre-op BMI was significantly higher in the BOAGB group compared to the other procedures. Additionally, a higher prevalence of diabetes was observed in the BOAGB group. The duration of surgery was significantly longer for the BOAGB procedure. No significant differences were found in surgical complications. Overall, all procedures resulted in significant excess weight loss (EWL) or change in BMI, improvement in comorbidities, and improved quality of life postoperatively. CONCLUSIONS: The BOAGB procedure, like OAGB and SG, demonstrated favorable weight loss outcomes and weight maintenance 1 year postoperatively without significant differences between the procedures. The BOAGB procedure is relatively new, with good bariatric outcomes and a favorable safety profile. Long-term study is needed to evaluate these various bariatric procedures' efficacy further.

Briefly trained medical students can effectively identify rheumatic mitral valve injury using a hand-carried ultrasound.

BACKGROUND: Rheumatic heart disease (RHD) is common and remains a major cause of morbidity, particularly in developing countries. Its diagnosis relies on expertise-dependent echocardiographic studies. We evaluated the accuracy of briefly trained examiners in identifying RHD utilizing a hand-carried cardiac ultrasound (HCU) device. METHODS: Three medical students received 8 hours of training in cardiac ultrasound, focused on assessment of rheumatic valve injury and its complications, using a prototype of HCU device, OptiGo. The students, blinded to the patients' medical condition, performed an auscultation-based physical examination and a focused HCU study on volunteers and patients with known RHD. A standard echocardiography study was used to validate the results. RESULTS: Each student performed a physical examination followed by an HCU study on 45 subjects (mean age 57 ± 14 years, 52% men), 14 of whom (31%) had rheumatic mitral valve injury. The students' averaged sensitivity for diagnosing RHD by HCU examination was 81%, while specificity was 95%. The interrater agreement (kappa) of the 3 students' HCU study and the standard echocardiography examination were between 0.55 and 0.88 (P < 0.01), and among the students themselves between 0.57 and 0.74 (P < 0.01), as students 1 and 2 had better results than student 3. Auscultation-based physical examination rendered low sensitivity (16%) for diagnosing rheumatic valve complications, namely mitral regurgitation and stenosis; however, it improved by 26% when students based their diagnosis on an HCU study. CONCLUSIONS: The ability to detect rheumatic valve injury using a portable ultrasound device by operators who only received brief echocardiographic training is remarkably high. However, the diagnosis of RHD complications is only modest. This result highlights the utility of portable cardiac ultrasound devices operated by basically trained personnel as a valuable diagnostic tool for RHD.

Morbidity characteristics of patients with congenital insensitivity to pain with anhidrosis (CIPA).

BACKGROUND: Congenital insensitivity to pain with anhidrosis (CIPA) is a congenital autonomic sensory neuropathy. In southern Israel, there are many patients with this disease. We here tried to characterize the different infections acquired by children with CIPA. METHODS: We collected all the available data about CIPA patients in southern Israel in the year 1991-2005, including the lesion types, area in the body where the infection occurs, and the treatment given. RESULTS: The current study included 30 children with CIPA, out of 44 known CIPA patients in southern Israel (68.2%). A total of 382 different episodes of infections, fever, orthopedic lesions, and jaw and mouth lesions led our patients to our outpatient clinic or resulted in hospitalization. CONCLUSION: We found that children with CIPA mainly have infections of the skin and skeleton, and that the most frequent pathogen is Staphylococcus aureus. We also found that a fair amount of these pathogens are resistant to conventional treatment regimens.

Objective estimates of the risk factors for death and length of hospitalization following burn injuries, Soroka University Medical Center, 2001-2002.

BACKGROUND: Burn injuries are extremely common and may impose a serious load on public health around the world. OBJECTIVES: To compare mortality rates and length of hospitalization according to the identified risk factors, extent of burn, gender and age. METHODS: In this retrospective study, data from 558 archive files of hospitalization due to burns as the diagnosis in patients of all ages, between the years 2001 and 2002, were analyzed to identify the risk factors for mortality and length of hospitalization. RESULTS: Males comprised 62.4% of the hospitalized burn patients. The mortality rate was 3.2% (n = 18) and among them 55.6% were women. Fifty percent of the fatality cases were over 48 years old, with statistically significant correlation of mortality rate and age. Most of the fatality cases (66.7%) had burns with total burn surface area (TBSA) larger than 40%. The multiple logistic regression model showed that leukocyte count on admission, TBSA, and age are the most important predictors of mortality. Smoke inhalation was not found to be an independent risk factor. CONCLUSIONS: Using a statistical model for estimating the mortality rate, this study found that white blood cell count at admission, TBSA, and age were the most significant predictors of mortality.

The impact of sleep deprivation on sleepiness, risk factors and professional performance in medical residents.

BACKGROUND: Prolonged working hours and sleep deprivation can exert negative effects on professional performance and health. 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 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 overtime.
