Background: Gastric cancer continues to be a leading cause of cancer death. The treatment approach varies, and preoperative staging is therefore crucial since an exploratory laparotomy for unresectable gastric cancer will be followed by an unacceptably high morbidity and mortality rate.

Objectives: To assess the added value of diagnostic laparoscopy to conventional methods of diagnosis such as computed tomography in avoiding unnecessary laparotomies.

Methods: A retrospective study on 78 patients scheduled for curative gastrectomy based on CT staging was conducted. DL[1] was performed prior to exploratory laparotomy.

Results: In 23 of 78 patients (29.5%), unexpected peritoneal spread not detected on preoperative CT was found. Fifty-five patients underwent radical gastrectomy, 15 patients were referred for downstaging and 8 patients underwent a palliative procedure.

Conclusions: Based on our results, DL should be considered in all gastric cancer patients scheduled for curative gastrectomy.

Background: Enteral nutrition in the critically ill patient is often complicated by gastrointestinal intolerance, manifested by a large gastric residual volume. The frequency of GRV[1] assessment and the intolerant level above which feeding is stopped is controversial.

Objectives: To evaluate a novel approach to EN[2] by allowing high GRV and once-daily assessment that was correlated with the paracetamol absorption test.

Methods: We conducted a pilot prospective study in an 18 bed general intensive care unit. The study group comprised 52 consecutive critically ill mechanically ventilated patients. Enteral nutrition was started at full delivery rate. Once-daily assessment of GRV with three consecutively repeated threshold volumes of 500 ml was performed before stopping EN. The paracetamol absorption test was performed and correlated to GRV. Patients were divided into two groups: low GRV (< 500 ml), and high GRV (at least one measurement of GRV > 500 ml). Clinical outcome included maximal calories delivered, incidence of pneumonia, ICU[3] length of stay, and ICU and hospital mortality.

Results: There were 4 patients (9.5%) with ventilator-associated pneumonia in the low GRV group and 3 (30%) in the high GRV group (P = 0.12). GRV was inversely correlated to paracetamol absorption; however, neither GRV nor paracetamol absorption was associated with the development of pneumonia. Both groups had similar ICU length of stay (11.0 ± 8.2 vs. 13.8 ± 14.4 days, P = 0.41), and similar ICU (21% vs. 40%, P = 0.24) and hospital mortality (35% vs. 40%, P = 1.0).

Conclusions: In critically ill mechanically ventilated patients, allowing larger gastric residual volumes, measured once daily, enables enteral feeding with fewer interruptions which results in high calorie intake without significant complications or side effects.

Background: Guidelines are frequently under-implemented in older patients with heart failure. Octogenerians are often excluded from clinical trials.

Objectives: To characterize the clinical profile of the oldest-old (age ≥ 80 years) heart failure patients hospitalized in a subacute geriatric hospital and to evaluate their management and 1 year outcome.

Methods: Patient characteristics and in-hospital course were retrospectively collected. Diagnosis of heart failure was based mainly on clinical evaluation in addition to chest X-ray results and echocardiographic findings when available.

Results: The study population comprised 96 consecutive unselected heart failure patients hospitalized from January to June 2003. The patients were predominantly women (67%), aged 85 ± 5 years, fully dependent or frail with a high rate of comorbidities. Adherence to guidelines and recommended heart failure medications was poor. Their 1 year mortality was 57%. According to logistic regression analysis, predictors of 1 year mortality were lower body mass index (odds ratio 0.86, 95% confidence interval 0.78–0.96) and high urea levels (OR[1] 1.04, 95% CI[2] 1.02–1.06).

Conclusions: Our study confirms that the management of oldest-old heart failure patients hospitalized in a subacute geriatric hospital was suboptimal and their mortality was exceptionally high.

Background: Falls are common events among hospital inpatients and constitute a major health problem in the rehabilitation setting. Many risk factors for falls have been identified for stroke patients, such as muscle weakness, medication side effects, hypoglycemia, hypotension, etc.

Objectives: To assess the risk factors for falls among patients hospitalized for rehabilitation following acute stroke.

Methods:  In a retrospective study of 56 falls over a period of 5 years in 41 stroke patients hospitalized for rehabilitation we surveyed the nurses’ safety risk assessment of the fall. Thirty patients fell once, 9 patients twice and 2 patients four times. The data were obtained from the medical and nursing records. Safety precautions were taken by the nurses for the entire group of patients.

Results: Most of the falls occurred among male patients who had reduced muscular tone (70%), paralysis (54%) and/or hypoesthesia in the involved side of the body. Patients who suffered from hemiplegia fell more often than those with hemiparesis (Wilcoxon rank sum test, P = 0.04, one-sided). Forty-eight percent of the falls occurred during the first month after the last stroke onset, 70% during the morning or the afternoon, and 62% occurred close to the patient’s bed. In 89% of falls the patients used hypoglycemic, antihypertensive, tranquilizing or neuroleptic drugs. Communication disorders (29%), hemianopia or blindness (21%) and visuospatial agnosia (18%) were incremental risk factors for falls. Fifty percent of the falls were caused by either an intrinsic or extrinsic mechanism.

Conclusions: These data suggest that the group of stroke patients at risk for falls in a rehabilitation department can be identified by a variety of impairment and functional assessments. The information may be potentially useful for designing interventions directed at reducing fall frequency among stroke survivors. 

Lymphadenitis is the most common manifestation of non-tuberculous mycobacteria infection in children. Its frequency has increased over the past few decades. Diagnosis is based on clinical presentation, purified protein derivative skin test, and bacterial isolation. Management options are surgery, antibiotics, or "observation only"; however, the optimal therapy for this condition is still controversial.

Head and neck cancer is the sixth most common cancer worldwide. HNCs[1] can originate in the skin or soft tissue, in the upper aerodigestive tracts (oral cavity, oropharynx, hypopharynx, larynx, nasopharynx, paranasal sinuses, salivary glands), or in the thyroid. In each of these sites, tumors vary not only by the primary site but also by pathophysiology, biological behavior and sensitivity to radiotherapy or chemotherapy. Management should be planned according to the tumor's characteristics, patient factors and expertise of the medical team. The main goals of therapy are ablation of the cancer while minimizing morbidity and preserving function and cosmesis. A multidisciplinary team is needed to achieve these goals. Early-stage HNC (stage I and II) should be managed with a single modality, and advanced tumors (stage III and IV) with multimodality therapy. Treatment should be directed to the primary tumor and the area of its lymphatic drainage – the neck lymph nodes. Evidence of metastases in the neck necessitates comprehensive clearance of regional lymphatic basins. However, even if there is no evidence of lymph nodes metastases, when the risk for positive neck lymph nodes exceeds 15–20% elective neck dissection is indicated. Advances in minimally invasive techniques now enable reliable microscopic and endoscopic procedures that mimic the open approaches. Development of contemporary surgical techniques and reconstructive means will help improve the quality of life of patients and prolong survival.

Background: Fracture of the scaphoid is the most common fracture of a carpal bone. Nevertheless, the diagnosis of SF[1] might be challenging. Plain X-rays that fail to demonstrate a fracture line while clinical findings suggest the existence of such a fracture is not uncommon. Currently there is no consensus in the literature as to how a clinically suspected SF should be diagnosed, immobilized and treated.

Objectives: To assess the current status of diagnosis and treatment of clinically suspected scaphoid fractures in Israeli emergency departments

Methods: We conducted a telephonic survey among orthopedic surgeons working in Israeli EDs[2] as to their approach to the diagnosis and treatment of occult SF.

Results: A total of 42 orthopedic surgeons in 6 hospital EDs participated in the survey. They reported performing a mean of 2.45 ± 0.85 clinical tests, with tenderness over the snuffbox area being the sign most commonly used.  A mean of 4.38 ± 0.76 X-ray views were ordered for patients with a clinically suspected SF. The most common combination included posterior-anterior, lateral, semipronated and semisupinated oblique views. All participating surgeons reported immobilizing the wrists of patients with occult fractures in a thumb spica cast based on their clinical findings. Upon discharge from the ED patients were advised to have another diagnostic examination as follows: 29 (69%) repeated X-rays series, 18 (43%) were referred to bone scintigraphy and 2 (5%) to computed tomography; none were referred to magnetic resonance imaging.

Conclusions: No consensus was found among Israeli orthopedic surgeons working in EDs regarding the right algorithm for assessment of clinically suspected SF. There is a need for better guidelines to uniformly dictate the order and set of tests to be used in the assessment of occult fractures.

Chronic disease management has been a rapidly growing entity in the 21st century as a strategy for managing chronic illnesses in large populations. However, experience has shown that disease management programs have not been able to demonstrate their financial value. The objectives of disease management programs are to create quality benchmarks, such as principles and guidelines, and to establish a uniform set of metrics and a standardized methodology for evaluating them. In order to illuminate the essence of disease management and its components, as well as the complexity and the problematic nature of performing economic calculations of their profitability and value, we collected data from several reports that dealt with the economic intervention of disease management programs. The disease management economic evaluation is composed of a series of steps, including the following major categories: Data/information technology, information generation, assessment/recommendations, actionable customer plans, and program assessment/reassessment. We demonstrate the elements necessary for economic analysis. Disease management is one of the most innovative tools in the managed care environment and is still in the process of being defined. Therefore, objectives should include the creation of quality benchmarks, such as principles and guidelines, and the establishment of a uniform set of metrics and a standardized methodology for evaluating them.

Background: Non-operative management following abdominal stab wounds is possible in selected patients who are both hemodynamically stable and do not have signs of peritonitis. However, the rate of failure of non-operative management is higher in Israel than in western countries.

Objectives: To assess the patterns of injury following abdominal stabbing.

Methods: Data from the Israeli Trauma Registry were used to identify all patients with abdominal stab injury admitted to eight different trauma centers between 1997 and 2004.

Results: The number of patients admitted per year more than doubled between 1997 and 2004, from 257 to 599. The percentage of patients with severe injury (Index Severity Score ≥ 16) increased from 9.4% to 19.0%. The incidence of multiple stab injuries almost doubled, from 37% to 62%.

Conclusions: Review of the data in the Israeli Trauma Registry indicates an increase in both absolute rate and relative incidence of serious stab injuries. This indicates that patterns of injury following stab wounds are not necessarily similar, not even within the same geographical area over time.
