Background: Gastric stump cancer is often described as a tumor with a poor prognosis and low resectability rates.

Objectives: To compare the pathological characteristics of gastric stump cancer patients with those of patients with proximal gastric cancer.

Methods: This retrospective study was based on the demographic and pathological data of patients diagnosed with gastric cancer and treated at Assaf Harofeh Medical Center during an 11 year period. The patients were divided into two groups: those undergoing proximal gastrectomy for proximal gastric cancer and those undergoing total gastrectomy for gastric stump cancer.

Results: Patients with gastric stump cancer were predominantly male, older (P = 0.202, not significant), and had a lower T stage with less signet-ring type histology, fewer harvested and fewer involved lymph nodes (P = 0.03, statistically significant) and less vascular/lymphatic involvement than patients with proximal gastric cancer.

Conclusions: The lower incidence of involved lymph nodes and lymphovascular invasion in gastric stump cancer as compared to proximal gastric cancer in this study may imply that the prognosis of gastric stump cancer may be better than that of proximal gastric cancer. However, to verify this assumption a study comparing patient survival is required.

Background: Diabetic retinopathy is a leading cause of adult blindness and accounts for about 10% of cases of legal blindness in Israel. Only about half of the patients with diabetes in Israel have regular eye examinations.

Objectives: To evaluate, for the first time in southern Israel, a new service for diabetic retinopathy screening that uses a mobile non-mydriatic mobile fundus camera in primary care patients.

Methods: Diabetic members of the largest health fund in southern Israel and over 18 years old were invited for non-mydriatic fundus examination between January and October 2009. Screening was performed by a trained photographer using the Topcon TRC NW-6S non-mydriatic camera in nine primary care centers.

Results: A total of 4318 diabetic patients were screened, of whom 53% were classified as normal. The incidence of diabetic retinopathy was 15.8% (1.2% had proliferative retinopathy and 2.4% had suspected macular edema and were referred for laser treatment). Other possible sight-threatening conditions were detected in 9.3%. Fundus pictures were inadequate for assessment in 16% of cases.

Conclusions: Diabetic retinopathy screening with a mobile non-mydriatic fundus camera improved the quality of care for diabetic patients in southern Israel. This screening method identified patients requiring prompt referral to the ophthalmologist for further complete eye examination. Extending this screening program to other areas in the country should be considered.

Background: Many patients in the internal medicine ward have anemia. The etiology for the anemia may be multifactorial and, in the setting of inflammatory process when the ferritin is increased, it is difficult to diagnose iron deficiency anemia. Soluble transferrin receptor (sTfR) had been suggested as an indicator for iron deficiency. No study has investigated the meaning of high sTfR as the only positive marker of iron deficiency anemia (IDA) caused by gastrointestinal tract (GIT) bleeding in hospitalized patients.

Objectives: To demonstrate the importance of high levels of sTfR as a marker for further GIT investigation in cases of anemia where the level of ferritin was normal or increased

Methods: We retrospectively assessed all patients in an internal medicine ward in our facility with anemia, high sTfR[1] levels (> 5.0 mg/L) and normal or high ferritin levels who underwent esophagogastroduodenoscopy and colonoscopy.

Results: Of 32 patients with anemia and normal or high ferritin levels and high sTfR, 22 patients (68%) had findings that explained IDA[2] (in some patients more than one finding). Those findings were colonic polyps (n=9), carcinoma of colon (n=4), duodenal ulcer (n=4), carcinoma of stomach (n=3), colitis (n=3), atrophic gastritis (n=1), erosive gastritis (n=1) and angiodysplasia (n=1).

Conclusions: High sTfR may be a good indicator of IDA caused by GIT[3] bleeding when the ferritin level is normal or high. GIT investigation is warranted in such cases.

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: Feeding neonates with humanized milk formula in maternity hospitals may increase the prevalence of milk allergy in infants. However, prospective studies of the possible allergenic effect of very early soy-based formula feeding are lacking.

Objectives: To assess the prevalence of soy allergy in infants fed soy-based formula in the first 3 days of life.

Methods: The study group included 982 healthy full-term infants born within a 7 month period at a hospital that routinely uses soy-based formula to supplement breastfeeding. In-hospital feeding was recorded and the parents were interviewed once monthly over the next 6 months regarding feeding practices and clinical symptoms suggesting soy allergy in the infant.

Results: Ninety-nine percent of the infants received soy-based formula supplement in hospital, and 33–42% at home. No cases of immediate allergic reaction to soy or soy-induced enterocolitis were reported.

Conclusions: The use of soy-based formula in the early neonatal period does not apparently increase the prevalence of soy allergy in infants followed for the next 6 months.

Background: ST-elevation myocardial infarction is caused by occlusive coronary thrombosis where antecedent plaque disruption occurs. When treating STEMI[1] the main goal is to achieve prompt reperfusion of the infarction area. Several studies have demonstrated the efficacy of an aspiration device before percutaneous coronary intervention in patients with acute myocardial infarction.

Objectives: To determine the added value of thrombus aspiration prior to primary PCI[2] by comparing AMI[3] patients with totally occluded infarct-related artery treated with routine primary PCI to those treated with extraction device prior to primary PCI.

Methods: The study group comprised 122 consecutive patients with AMI and a totally occluded infarct artery (TIMI flow 0) who underwent primary PCI. The patients were divided into two groups: 68 who underwent primary PCI only (control group) and 54 who underwent primary thrombus extraction with an extraction device before PCI (extraction group). Baseline clinical and lesion characteristics were similar in both groups. Final TIMI grade flow and myocardial blush as well as 1 year mortality, target lesion revascularization, recurrent myocardial infarction, unstable angina and stroke were compared between the two groups.

Results: Primary angiographic results were better for the extraction group versus the control group: final grade 3 TIMI flow was 100% vs. 95.6% (P = 0.03) and final grade 3 myocardial blush grade 50% vs. 41.18% (although P was not significant). Long-term follow-up total MACE[4] showed a non-significant positive trend in the extraction group (12.96% vs. 24.71%, P = 0.26).

Conclusions: The use of extraction devices for intracoronary thrombectomy during primary PCI in patients with totally occluded infarct artery significantly improved epicardial reperfusion in the infarct-related vessel and showed a trend for more favorable long-term outcome.

Background: Infiltrating ductal carcinoma and infiltrating lobular carcinoma account for more than 90% of all invasive breast cancer histological types. The rate of ILC[1] is reported to be increasing steadily in the United States and Europe.

Objectives: To describe the trend in the incidence of ILC in a large cohort of patients who underwent surgery in a single institution over an 18 year period.

Methods: Our comprehensive database of 2175 consecutive patients with invasive breast cancer diagnosed during the period 1992–2009 served for the analysis. Several potential factors associated with lobular carcinoma as compared with ductal carcinoma were evaluated.

Results: During this period, a 2.4-fold increase in the incidence of pure ILC was noted, from 4.6% in the years 1992–1994 to 10.9% in 2004–2006, followed by a modest decrease to 8.7% in 2007–2009. A significant association of lobular malignancies with external hormonal use was noted, including hormone replacement therapy exposure in patients diagnosed at age 50–64, and ovarian overstimulation during in vitro fertilization in those diagnosed at age 50 or less.  

Conclusions: Better diagnostic tools – such as the liberal use of ultrasound and magnetic resonance imaging – and more accurate pathological definition for ILC type appear to influence the changes in the incidence of ILC in the subgroups of invasive breast cancer.

The courts have recently become increasingly involved in the administration of compulsory psychiatric services in Israel. Data reveal a gradual increase in the rate of court-ordered hospitalizations according to Section 15 of the Law for the Treatment of the Mentally Ill. This paper examines the implications of this trend, particularly the issues of security and safety in psychiatric hospitalization. We present highlights from extensive British experience, focusing on the implications on forensic psychiatry in Israel. We review the development of the hierarchy of security in the British psychiatric services, beginning in the early 1970s with the establishment of the Butler Committee that determined a hierarchy of three levels of security for the treatment of patients, culminating with the establishment of principles for the operation of medium security units in Britain (Read Committee, 1991). These developments were the basis for the forensic psychiatric services in Britain. We discuss the relevance of the British experience to the situation in Israel while examining the current status of mental health facilities in Israel. In our opinion, a safe and suitable environment is a necessary condition for a treatment setting. The establishment of medium security units or forensic psychiatry departments within a mental health facility will enable the concentration and classification of court-ordered admissions and will enable systemic flexibility and capacity for better treatment, commensurate with patient needs.

Background: One of the ominous complications following proximal gastrectomy or total gastrectomy is a leak from the esophagogastric or esophagojejunal anastomosis. An upper gastrointestinal swallow study is traditionally performed to confirm the anastomotic patency and lack of any leak before oral feeding can be initiated.

Objectives: To challenge the routine use of UGISs[1] following proximal or total gastrectomy in order to check the integrity of the gastroesophageal or jejunoesophageal anastomosis.

Methods: The charts of 99 patients who underwent PG[2] or TG[3]  for malignant pathology were retrospectively reviewed. UGISs were performed on day 6 following surgery using a water-soluble material.

Results: The UGISs were normal in 95 patients, with none displaying any complication related to the gastroesophageal or jejunoesophageal anastomosis. All four patients who experienced a leak from the anastomosis had an early stormy postoperative course.

Conclusions: Routine use of an UGIS to detect a leak following PG or TG is not justified. UGIS should be performed whenever signs of abdominal sepsis develop following this type or surgery.

Background: An accurate preoperative definition of tumor and lymph node status is needed for reaching the correct decision regarding rectal cancer treatment. Transrectal ultrasonography is the most commonly used diagnostic modality for the local staging of rectal cancer.

Objectives: To determine the accuracy of TRUS[1] in the staging of rectal cancer.

Methods: We conducted a retrospective study on 95 patients evaluated by TRUS. The rectum was subdivided into two parts (lower and upper).

Results: Sixty patients underwent radical surgery. Of these, 34 received no preoperative chemo-irradiation owing to µT1, µT2 tumor or the patient’s choice (neo-adjuvant treatment was suggested to patients with adenocarcinoma that proved to be µT3). The overall accuracy rate was 80% for T stage. Overstaging was found in 13.3% and understaging in 6.7%.The N-stage was correctly assessed in 70%. The overall accuracy rate for tumors was 73.9% in the lower part and 90.9% in the upper. A trend towards a lower accuracy rate for low-lying tumors compared to high-located rectal tumors was found (P = 0.532), which did not reach statistical significance.

Conclusions: TRUS gave better results for T1 and T3 stage rectal tumors but was inaccurate for stage T2, indicating the possible need for local excision in order to base the final treatment for T2 tumors on pathologic staging.

Background: Hypocalcaemia following thyroid and parathyroid surgery is a well-recognized potential complication.

Objectives: To determine the utility of intraoperative quick parathormone assay in predicting severe hypocalcemia development following parathyroidectomy for a single-gland adenoma causing primary hyperparathyroidism.

Methods: A retrospective cohort study was performed. IO-QPTH[1] values were measured at time 0 (T0) before incision, and 10 (T10) and 30 minutes (T30) following excision of the hyperfunctioning gland. Percent decrease in IO-QPTH at 10 minutes (T10), maximum percent decrease of IO-QPTH value, and lowest actual IO-QPTH value obtained at surgery were used to determine any correlation with the development of postoperative hypocalcemia requiring treatment.

Results: Percent decrease in IO-QPTH at 10 minutes, maximum percent decrease in IO-QPTH and lowest IO-QPTH value did not correlate with the lowest postoperative calcium levels measured 18 hours after surgery (r = 0.017, P = 0.860 r = 0.018, P = 0.850 and r = 0.002, P = 0.985 respectively). For the purposes of our analysis, patients were subdivided into three groups. Group 1 comprised 68 patients with normal calcium levels (serum Ca 8.6¨C10.3 mg/dl) Group 2 had 28 patients with hypocalcemia (8.1¨C8.6 mg/dl) Group 3 included 12 patients with severe hypocalcemia (calcium level ¡Ü 8.0 mg/dl) requiring calcium supplementation due to symptoms of hypocalcemia. There was no difference between the three groups in the lowest IO-QPTH value (P = 0.378), percent decrease in IO-QPTH (P = 0.305) and maximum percent decrease in IO-QPTH (P = 0.142).

Conclusions: IO-QPTH evaluation was not useful in predicting the group of patients susceptible to develop severe postoperative hypocalcemia.
