Abstract: Introduction: Post-varicocelectomy pain is a considerable pain with probability of promotion toward chronicity. Some reasons, including surgical technique or nerve injury and inappropriate attention to treatment of acute pain play role in the emergence of acute pain. The pain could lead to limitation in movement and working, patient dissatisfaction and waste of medical resources. Transcutaneous electrical nerve stimulation (TENS) therapy as the patient control analgesia (PCA) is associated with reduction of pain intensity and analgesic consumptions. This study aimed to evaluate the effect of TENS therapy on reducing the acute and chronic pain following varicocelectomy. Methods and Materials: The study was conducted after obtaining the approval of the local Institute Ethics Committee and written informed consent from all of the patients. Eighty patients scheduled for undergoing varicocelectomy, were randomly classified according to a randomization list prepared using online software at a 1:1 ratio to Groups A (intervention group) and B (placebo group). In postoperative and recovery period, Group A received TENS therapy for 30 minutes in parallel to surgical scar with high frequency by sensory level. Group B was treated with off-device. The treatment course was replicated for the two groups at 2, 6, 12 and 24 hours after operation. Then, postoperative pain was measured by VAS (visual analogue scale) at the same time and after 1 week and 1, 2 and 3 months. The amount of used analgesics was recorded. Results: The results showed that based on the VAS, pain significantly decreased after intervention in 2 hours (25% with VAS = 5 versus 32.5% with VAS = 8 in control group). The differences among, amount of used analgesics at 2, 6 and 12 hours were significant with p-value = 0.001, <0.0001 and =0.02, respectively. Conclusion: TENS therapy could efficiently decrease pain degree for hours, weeks and months after varicocelectomy; this was associated with decreased post-operation analgesic requirements.

Abstract: Introduction: Careful history and physical examinations are the best ways for preoperative evaluation. Currently, we are recommended to rely on doing them rather than unnecessary and costly laboratory tests for confirmation or diagnosis of disease. The aim of study is the survey of CRP level association to decide further evaluation and expert consultation, newly diagnosed problems and possible effect on postoperative mortality and morbidity. Methods and Materials: In a descriptive retrospective study, hospital documentation of 620 patients older than 18 years undergone heart surgery in Tabriz Shahid Madani hospital was evaluated. Addition to plasma CRP level, patient’s demographic information, type of surgery, preoperative significant tests, delay time in surgery start time after anesthesiology visit, cause of requested specialty consultation and treatment recommendation, postoperative complications and mortality rate were recorded and analyzed. Patients were classified according to preoperative plasma CRP level to five groups as negative, +1, +2, +3 and not measured (i.e. they considered as normal (0 - 5 mg/l), mildly (5 - 40 mg/l), moderately (40 - 200 mg/L) or severely increased (>200 mg/l) groups). Results: Of 620 patients, 402 were male and 218 were female. There was not statistically significant correlation among demographic variables (gender, age, weight, and height), heart disease diagnosis and the type of surgery in five groups. In 79 individuals, they were done specialty consultations that most common of them were neurology consultation because of impaired renal laboratory tests. Only 2 cases were due to high CRP level. In any of cases, this preoperative consultation didn’t result from new disease cases. CRP plasma level hadn’t association with preoperative red blood cell sedimentation level. Prevalence of preoperative acute myocardium infarction was higher in patients with high CRP level. In group +1, delay time was lower than other groups. The most common causes were cardiac causes. There wasn’t statistically significant correlation between CRP level and different postoperative complications. There wasn’t significant association between ICU stay time and postoperative hospital stay time and plasma high CRP level. Conclusion: Probably, plasma CRP level increases before surgery in acute myocardial infarction and results in high mortality rate. It seems that routine measurement of CRP in candidates for heart operation is beneficial for mortality rate prediction, so its increasing level can’t help to diagnosis newly cases

Abstract: Introduction: The estimation of blood loss rate during surgery for prediction of transfusion of blood or blood products requirement is important for surgeon and anesthesiologist. In regard to various results and lack of definite index for start of transfusion in operating rooms, the assessment of blood loss reduction is necessary. The aim of study was evaluation of hemoglobin (Hb) value and hemorrhage estimation rate. Methods and materials: 48 cases underwent major orthopedic surgery with high probability of intraoperative blood loss rate was included in study. Hb, hematocrit (Hct) and basic vital signs were measured preoperatively and blood loss rate was estimated by using of blood volume in suction, bloody gases and blood loss in operation field and recorded. The blood sample per 100 mL blood loss was sent to laboratory. For transfusion deciding based on Hb, we did not any intervention. Results: 26 males and 22 females were included in study. Our results showed that Hb value of males was higher significantly of females in preoperative period. After beginning of blood loss, Hb and Hct values declined with fixed slope and there was high negative correlation between them. First, intraoperative systolic and diastolic pressures declined with high slope and then reduced with mild slope. Hb value reduced significantly per 100 mL blood loss. During survey, no alteration in urine output did not be observed. Conclusion: Present study showed that much more intraoperative blood loss could reduce Hb with high correlation coefficient and measurement of it is efficient on transfusion.

Abstract: Introduction: The typical order of nothing per oral (NPO) after midnight has been challenged in recent years, thus the American Society of Anesthesiology (ASA) revised in practice guidelines for preoperative fasting in healthy patients undergoing elective procedures, but many studies have showed that guidelines were not considered in clinical practice. The aim of this study was to evaluate the adjustment of preoperative NPO time with fasting guidelines in adult elective ophthalmic surgeries in a university educational ophthalmology hospital in Tabriz, Iran. Methods: In 3 months period, this descriptive study was conducted on 250 patients who scheduled for elective eye surgery. The investigator interviewed with patients before beginning of anesthesia and evaluated fasting duration for heavy meal, light meal and clear liquids and his or her satisfaction from NPO time and also investigated which staff recommended NPO time before anesthesia induction. Results: Fasting duration from heavy and light meal and clear liquids was 14.31 hours (8 - 23 hours), 12.46 hours (6 - 21 hours) and 11.54 hours (3 - 18 hours), respectively, that was not consistent with ASA guidelines. The discontent of the patients from prolonged NPO time was 60.8%. The most complaint was thirsty (42%). Ward nurses were the personnel who had the primary role in patients fasting time period (47.6%). Conclusion: Preoperative fasting duration for heavy and light meal and clear liquids for elective ophthalmic surgery in this teaching hospital was very long and not consistent with ASA guidelines. Ward nurses had the major role in this malpractice. Thus it seems that personnel education may be very helpful.

Abstract: On a prospective cross sectional study, two hundred and seventy women from urban areas of Northwest Iran were recruited for participation during their first eight weeks of pregnancy. Body mass index (BMI) was categorized and gestational weight gain was divided into two groups of normal and abnormal based on recommendations of Institute of Medicine (IOM) published in 1990. Chi square and one way ANOVA were used in the univariate analysis of the association between weight gain and corresponding adverse outcomes including cesarean, preterm labor and low neonatal birth weight. Adjusted odds ratios for adverse outcomes were determined by multiple logistic regression models, while controlling for the following factors: maternal age, parity, and education.Both pre-pregnancy BMI < 19 and abnormal weight gain during pregnancy were found to be associated with low neonatal birth weight defined as < 2500 g. Abnormal weight gain, during pregnancy was not related to an increased risk of preterm labor or cesarean delivery but it was highly associated with low birth weight (LBW)(P < 0.05).Low pre-pregnancy BMI is an established risk factor for LBW. Abnormal gestational weight gain may further complicate the pregnancy as an additional risk factor for neonatal LBW. All women, regardless of their pre-pregnancy BMI may be at risk for abnormal weight gain and hence low birth weight. Pre-pregnancy and gestation nutritional assessments remain significant part of all prenatal visits.Maternal nutritional status is important for health and quality of life in women and their growing fetus. Maternal pre-pregnancy nutritional status and pregnancy weight gain also affect the health and survival of the newborn. Consequently, various recommendations have been made about weight gain during pregnancy [1]. The Institute of Medicine (IOM) report which released in 1990, categorized according to the pre-pregnant Body Mass Index (BMI) (table 1). This report confirmed a strong association between weight g
Design of Secure Microsystems Using Current-to-Data Dependency Analysis  [PDF]

Circuits and Systems (CS) , 2013, DOI: 10.4236/cs.2013.42019
Abstract:

This paper presents a method for designing a class of countermeasures for DPA attacks based on attenuation of current variations. In this class of countermeasures, designers aim at decreasing the dynamic current variations to reduce the information that can be extracted from the current consumption of secure microsystems. The proposed method is based on a novel formula that calculates the number of current traces required for a successful DPA attack using the characteristics of the microsystem current signal and the external noise of the measurement setup. The different stages of the proposed method are illustrated through designing an example current flattening circuit. Meanwhile validity and applicability of the proposed formula is verified by comparing theoretical results with those obtained experimentally for the example circuit. The proposed formula not only estimates the required level of attenuation for a target level of robustness defined by design requirements, it also predicts the effectiveness of a countermeasure using simulation results therefore dramatically reducing the time to design of secure microsystems.
