Needlestick injury among interns and medical students in the Occupied Palestinian Territory.

The aim of this study was to determine the prevalence of needlestick injury (NSI) among interns and medical students as well as their knowledge of, attitude towards and their protective strategies against exposure to bloodborne pathogens. A cross-sectional study was conducted among 272 participants using a self-administered questionnaire. Just over 40% of the participants had experienced at least 1 NSI. Wound suturing was the most common cause of injury (33.5%), and the highest incidence (55.5%) was in the emergency room. Failure to report the injury to health representatives was recorded for 48.6% of NSIs. Only 46.7% of the interns had received the hepatitis B vaccine whereas most of the students (76.8%) had completed their vaccination schedule (P < 0.001). Participants were found to be at a high risk of NSIs and bloodborne infections.

Implementation of hazard analysis critical control point in jameed production.

The average of standard plate count and coliforms, Staphylococcus aureus and Salmonella counts for three home-made jameed samples, a traditional fermented dairy product, before applying hazard analysis critical control point system were 2.1 × 10(3), 8.9 × 10(1), 4 × 10(1) and less than 10 cfu/g, respectively. The developed hazard analysis critical control point plan resulted in identifying ten critical control points in the flow chart of jameed production. The critical control points included fresh milk receiving, pasteurization, addition of starter, water and salt, straining, personnel hygiene, drying and packaging. After applying hazard analysis critical control point system, there was significant improvement in the microbiological quality of the home-made jameed. The standard plate count was reduced to 3.1 × 10(2) cfu/g whereas coliform and Staphylococcus aureus counts were less than 10 cfu/g and Salmonella was not detected. Sensory evaluation results of color and flavor of sauce prepared from jameed showed a significant increase in the average scores given after hazard analysis critical control point application.

Low-molecular-weight heparin in the treatment of recurrent IVF-ET failure and thrombophilia: a prospective randomized placebo-controlled trial.

INTRODUCTION: Recently, thrombophilia (acquired and inherited) has been implicated in recurrent IVF-ET failure. The objective of this study was to determine the effect and safety of thromboprophylaxis using low-molecular-weight heparin (LMWH) in women with recurrent in vitro fertilization (IVF)-embryo transfer (ET) failure and thrombophilia. METHODS: Eighty-three women with history of three or more previous IVF failures and who had at least one thrombophilic defect were eligible for this study. Patients were randomly allocated into two groups: Group A (n = 42) received enoxaparin 40 mg/day, and group B (n = 41) received placebo (NaCl 0.9%). Both treatments started on the day of ET and continued until delivery or foetal demise was diagnosed. The primary outcomes were the implantation, pregnancy and live birth rates. RESULTS: Patients who received LMWH for thromboprophylaxis had a significant increase in the implantation and pregnancy rates compared with the placebo group (20.9% vs. 6.1% and 31% vs. 9.6%, respectively; p < 0.001 and p < 0.05, respectively). A significant increase in the live birth rate was observed in the heparin-treated group compared with placebo (23.8% vs. 2.8%, respectively; p < 0.05). The abortion rate was significantly higher in the placebo-treated group compared to the heparin-treated group (p < 0.05). The frequency of treatment complications did not differ between the two study groups. CONCLUSIONS: LMWH is a safe and effective thromboprophylactic treatment for women with thrombophilia and recurrent IVF-ET failures. The implantation rate, pregnancy and live birth rates are significantly increased with such treatment.

Cesarean section rate: much room for reduction.

OBJECTIVE: To examine the indications and rate of cesarean section in referral hospitals. METHODS: Between January 2003 and December 2005, a total of 11,506 women delivered at King Hussein Medical Center, of which 2,075 cesarean sections (CS) were performed. Patients who underwent cesarean section were divided into three age subgroups: < 25 yr (n = 3,118), 25-35 (n = 6,147), and > 35 yr (n = 2,241), and two parity subgroups - primiparous (n = 3,326) and multiparous (n = 8,180). Information abstracted included maternal characteristics and indications for CS. Statistical analyses were performed using the Pearson chi-square test and Fisher's exact test to evaluate differences between the various subgroups. RESULTS: From a total of 11,506 deliveries that took place, 2,075 cesarean sections were performed with an incidence of 18%. According to age, the CS rate was 11.85%, 20.5% and 19.9%, respectively, in the three age subgroups. According to parity, the CS rate was 16.3% and 18.7% in the primiparous and multiparous women, respectively. When matched to age, the indications for CS showed no significant difference among the three age subgroups. When matched to parity, the indications also showed no significant difference between the two parity subgroups except for dystocia which was significantly higher in the primiparous compared to multiparous women (p < 0.01), and for repeated CS which was significantly higher in the multiparous compared to primiparous women (p < 0.0001) CONCLUSION: Some indications for cesarean section such as dystocia and fetal distress were over-utilized resulting in a high CS rate. Proper management of labor and precise interpretation of fetal heart tracing might be effective in reducing the cesarean section rate.

Prepubertal growth in children with long-term parenteral nutrition.

In children who depend on long-term parenteral nutrition (PN), a major goal is to obtain optimal growth. The aim of this retrospective study was to analyze growth in children on long-term cyclic nocturnal home PN, over at least 8 years before puberty. Nine boys and 7 girls were studied. Their mean age at the time of study was 11 years with a mean PN duration of 10.5 (8.6-16.4) years. Diseases were short bowel syndrome (5), intractable diarrhea (4), chronic intestinal pseudo-obstruction (4) and long segment Hirschsprung's disease (3). In each child, periods of at least 2 years were analyzed: either periods of regular growth (R: height gain >50th percentile), or slow growth (S: height gain < or =25th percentile). Results were expressed as mean +/- SD. Comparisons were performed using either Student's test for unpaired data or Wilcoxon's test for paired data. PN provided a mean of 224 +/- 80 mg nitrogen/kg/day and 43 +/- 14 kcal/kg/day equivalent to 50% of recommended supplies. At the time of study, the population presented with weight (W) = -0.7 +/- 0.8 SD and height (H) = -1.5 +/- 1.3 SD. The difference between W and expected W for H (W/H) was significant (p < 0.002). W/H ratio was 105 +/- 11%. For the total PN duration, weight gain was +0.2 +/- 1.5 SD and height loss was -0.75 +/- 1.4 SD. An excess weight gain occurred in parallel with the deflection of height gain. Of the 16 children, regular prepubertal growth was achieved in 4 only. The other 12 showed alternate periods of R and S. In 8 of them, 26.5 years of R and 33.5 years of S were compared, each child being his own control. PN nitrogen and energy supplies were significantly higher during R periods than during S periods. In the absence of any disease or treatment explaining the failure to thrive, inadequate PN supplies, especially in terms of nitrogen supply, are thought to be responsible for a negative nitrogen balance and slowed growth. In case of any deflection away from the individual growth curve, it is recommended to adjust the PN supply early, especially nitrogen supply.

[Obesity in children and adolescents, mental disorders and familial psychopathology]. / Obésité de l'enfant et de l'adolescent, troubles mentaux et psychopathologie familiale.

OBJECTIVE: The purpose of this study was to evaluate the type and frequency of psychopathological disorders observed in obese children and adolescents. We also looked for a correlation between psychic disorders in the obese children, the degree of obesity and paternal psychopathology. PATIENTS AND METHODS: The study group included 84 obese children and adolescents aged 5 to 16 years (mean age 10.9 +/- 2.8 years). There were 55 girls and 29 boys. The z-score expressing deviation from the ideal body mass index (IMC) varied from +2 to +10.6 (mean 4 + 1.9). Psychopathological disorders observed in these obese patients were compared in children and adolescents with insulin-dependent diabetes mellitus. The standard diagnostic interview (K-SADS PL) and self-administered questionnaires (Sielberger STAIC-Trait for anxiety and CDI for depression in children or CBCL or GHQ for their parents) were also used to evaluate psychic disorders. RESULTS: More than half of the obese children (47 out of 84) had a DSM-IV diagnosis, often involving anxiety (n = 28). The rate of internalized and externalized psychopathological disorders (measured by STAIC-Trait and CBCL) was higher in the obese children than in the diabetics. The children's psychopathological disorders were more marked if their parents were perturbed, particularly when their mother had an internalized disorder. No correlation was found between the degree obesity and psychopathological disorders in the obese children and adolescents. CONCLUSION: Our findings show the frequency of mental disorders in obese children and point out the importance of parental psychopathology. This underlines the usefulness of a pedopsychiatric approach implicating the entire family for therapeutic management of these patients.

Spinal versus general anesthesia for elective cesarean delivery: a prospective comparative study.

OBJECTIVE: To study the efficacy and safety of spinal anesthesia for elective cesarean section as compared with general anesthesia. PATIENTS AND METHODS: 175 women undergoing elective cesarean section were studied prospectively. They were allocated into two groups; the first group (n=60) received spinal anesthesia, and the second one (n=115) received general anesthesia for elective cesarean section. Preoperative and intraoperative BP and IV fluids were recorded. Chi-Square and Fisher's exact tests were used to compare differences between the two groups; p < 0.05 was considered significant. RESULTS: There were no differences between the two groups in terms of demographics, indication for elective cesarean section, operative time, gestational age, 1 and 5-min Apgar scores, and the means of preoperative and postoperative systolic and diastolic BP. A statistically significant increase was observed in terms of hypotension, postoperative analgesia, pre-induction and intraoperative IV fluids in the spinal group as compared to the general anesthesia group (p < 0.001, p < 0.01, and p < 0.01, respectively). CONCLUSION: Spinal anesthesia is as effective as a general anesthesia. Maternal and fetal outcome are favorable. Maternal hypotension can be managed successfully with modest doses of ephedrine and IV fluid infusions. It provides sufficient postoperative analgesia allowing the mother to have more vitality and comfort than those who receive general anesthesia.

Central venous catheter-related infections in children on long-term home parenteral nutrition: incidence and risk factors.

BACKGROUND AND AIMS: This study aimed to assess the incidence and etiology of central venous catheter (CVC) infections in children on home parenteral nutrition (HPN). METHODS: 207 CVC-years were studied retrospectively in 47 children on HPN, aged 8.1+/-5.0 years. RESULTS: 125 CVC were used (means: 2.6 CVC/patient and 21 months utilization/CVC). Half of the hospitalizations (162) were due to proven CVC-related infections. The mean infection incidence was 2. 1/1000 HPN days. The total population divided in two groups below and above this value: group one including 24 children, incidence < or = 2.1 per 1000 days (mean: 0.83) and group two including 23 children, incidence >2.1 per 1000 days (mean: 4.3). No differences were found between the two groups in terms of underlying disease, presence of ostomies, age at the time of HPN onset, or micro-organisms responsible. The only differences (p<0.05) were the mean duration of HPN (longer in group one) and the delay between HPN onset and the first infection (longer in group one). CONCLUSIONS: This study does not highlight any risk factors for CVC infection. However, early CVC infections after HPN onset appear to predict a bad prognosis.

Blood lead level in the Jordanian population.

OBJECTIVE: To determine the blood lead level in the non-occupationally exposed Jordanian population as a baseline for comparative studies. METHODS: Seven hundred and forty six blood samples were collected and analyzed using Graphic Furnace Atomic Absorption Spectrophotometry. A representative sample for the Jordanian community was selected. RESULTS: The arithmetic mean for blood lead level in the whole sample was 1.96 microg/d1 which was lower than the other means determined by international studies. CONCLUSION: The blood lead level among the Jordanian population was found to be less than the levels in other countries, this may be partly explained by the low levels of lead in air and water.

Prognostic value of preoperative squamous cell carcinoma antigen level in patients surgically treated for cervical carcinoma.

Preoperative evaluation of squamous cell carcinoma antigen (SCCa) was performed in 220 patients with surgically treated early-stage carcinoma of the cervix. The median duration of follow-up was 1.9 years. SCCa was significantly higher in tumors with a squamous element (P < 0.001). There was a squamous element in 171 tumors. SCCa was elevated (>2 ng/ml) in 21.6%. Significantly higher levels were associated with stage II disease (P < 0.001), tumors >4-cm size (P < 0.001), and lymph node metastases (P < 0.001). The positive predictive value for lymph node metastases at >2, >4, and >8.6 ng/ml SCCa is 51.4, 70.0, and 100% and the sensitivity is 58.1, 45.2, and 22.6%, respectively. Low SCCa is a poor predictor of absence of lymph node metastasis. The median SCCa for patients who developed tumor recurrence was greater than those who remained disease free (1.7 and 1.0 ng/ml, respectively, P = 0.009); however, in a multivariate analysis only lymph node metastasis and tumor size were of independent prognostic significance (P = 0.002 and P = 0.004, respectively). SCCa level >8.6 ng/ml is highly predictive of lymph nodal disease. There is no independent prognostic significance in patients with early-stage surgically treated cervical carcinoma.
