BMC Research Notes , 2011, DOI: 10.1186/1756-0500-4-311
Abstract: This is a retrospective case-control study conducted at Kassala hospital, eastern Sudan. Medical files of pregnant women with severe anaemia (haemoglobin (Hb) < 7 g/dl, n = 303) who delivered from January 2008 to December 2010 were reviewed. Socio-demographic and obstetric data were analysed and compared with a similar number of women with mild/moderate anaemia (Hb = 7-10.9 g/dl, n = 303) and with no anaemia (Hb > 11 g/dl, n = 303). Logistic regression analysis was performed separately for each of the outcome measures: preeclampsia, eclampsia, preterm birth, low birth weight (LBW) and stillbirth.There were 9578 deliveries at Kassala hospital, 4012 (41.8%) women had anaemia and 303 (3.2%) had severe anaemia. The corrected risk for preeclampsia increased only in severe anaemia (OR = 3.6, 95% CI: 1.4-9.1, P = 0.007). Compared with women with no anaemia, the risk of LBW was 2.5 times higher in women with mild/moderate anaemia (95% CI: 1.1-5.7), and 8.0 times higher in women with severe anaemia (95% CI: 3.8-16.0). The risk of preterm delivery increased significantly with the severity of anaemia (OR = 3.2 for women with mild/moderate anaemia and OR = 6.6 for women with severe anaemia, compared with women with no anaemia). The corrected risk for stillbirth increased only in severe anaemia (OR = 4.3, 95% CI: 1.9-9.1, P < 0.001).The greater the severity of the anaemia during pregnancy, the greater the risk of preeclampsia, preterm delivery, LBW and stillbirth. Preventive measures should be undertaken to decrease the prevalence of anaemia in pregnancy.Anaemia during pregnancy is a major public health problem, especially in developing countries [1]. It affects 41.8% of pregnant women globally, with the highest prevalence in Africa [2]. There is however significant variation in the prevalence of anaemia both within and between countries, necessitating a need for local data to help to improve preventive programmes. Anaemia during pregnancy, especially severe anaemia, is associat

Tajeldin M Abdallah, Ishag Adam, Mutaz A Abdelhadi, Mohammed F Siddig, AbdelAziem A Ali
BMC Research Notes , 2012, DOI: 10.1186/1756-0500-5-202
Abstract: Out of 646, 234 (36.2%) adults had anaemia; 68 (10.5%); 129 (20.0%) and 37 (5.7%) had mild, moderate and severe anaemia, respectively. In logistic regression analyses, age (OR?=?1.0, CI?=?0.9–1, P?=?0.7), rural vs. urban residency (OR?=?0.9, CI?=?0.7–1.3, P?=?0.9), female vs. male gender (OR?=?0.8, CI?=?0.6–1.1, P?=?0.3), educational level?≥?secondary level vs. < secondary level (OR?=?1.0, CI?=?0.6–1.6, P?=?0.8) and Hudandawa vs. non-Hudandawa ethnicity (OR?=?0.8, CI?=?0.6–1, P?=?0.1) were not associated with anaemia.There was a high prevalence of anaemia in this setting, anaemia affected adults regardless to their age, sex and educational level. Therefore, anaemia is needed to be screened for routinely and supplements have to be employed in this setting.Anaemia is a major public health problem, especially in developing countries [1]. It is common in adult and the prevalence of anaemia is increasing with advancing age [2]. There is however, a significant variation in prevalence of anaemia, both within and between countries, necessitating a need for local data for preventive measures. Anaemia is associated with adverse outcomes among adult such as reduced quality of life, depression, increased disability, higher risk of Alzheimer disease and increased risk of mortality [3,4]. Anaemia is a multifactorial condition and the increased heterogeneity in the distribution of social and biological factors with advancing age makes the epidemiology of anaemia a real challenge [5]. Epidemiology of anaemia is important for deciding the control strategies. Thus, studies investigating these parameters are vital and of great interest, so as to provide health planners and caregivers with fundamental guidelines for the implementation of preventive measures. Therefore, the aim of this work was to investigate the prevalence and predictors of anaemia among adults in Kassala, Eastern Sudan.This was a cross sectional community- based survey of adults (>15 year old) residents in Kassala, Ea

Abstract: Near-miss cases and events (hemorrhage, infection, hypertensive disorders, anemia and dystocia), maternal deaths and their causes were retrospectively reviewed and the mortality index for each event was calculated in Kassala Hospital, eastern Sudan over a 2-year period, from January 2008 to December 2010. Disease-specific criteria were applied for these events.There were 9578 deliveries, 205 near-miss cases, 228 near-miss events and 40 maternal deaths. Maternal near-miss and maternal mortality ratio were 22.1/1000 live births and 432/100 000 live births, respectively. Hemorrhage accounted for the most common event (40.8%), followed by infection (21.5%), hypertensive disorders (18.0%), anemia (11.8%) and dystocia (7.9%). The mortality index were 22.2%, 10.0%, 10.0%, 8.8% and 2.4% for infection, dystocia, anemia, hemorrhage and hypertensive disorders, respectively.There is a high frequency of maternal morbidity and mortality at the level of this facility. Therefore maternal health policy needs to be concerned not only with averting the loss of life, but also with preventing or ameliorating maternal-near miss events (hemorrhage, infections, hypertension and anemia) at all care levels including primary level.Maternal near-miss cases of women who nearly died but survived a complication during pregnancy, childbirth or postpartum (maternal near miss or severe acute maternal morbidity) are increasingly recognized as useful means to examine quality of obstetric care since pregnancy complications occur in 15% of women worldwide. The practical implementation of maternal near miss concept should provide an important contribution to improving quality of obstetric care to reduce maternal deaths and improve maternal health [1-4]. More than half a million women die annually as a result of pregnancy. Therefore, it is important to investigate the causes of maternal deaths and maternal morbidities to reduce the maternal mortality ratio and thus meet the Fifth Millennium Development Go

Surgical Science (SS) , 2015, DOI: 10.4236/ss.2015.63016
Abstract:

Background:?Many ventral hernia repair methods have been described among surgeons. The traditional primary repair entails a laparotomy with suture approximation of strong fascial tissue on each side of the defect. However, recurrence rates after this procedure range from 12% to 24% during long-term follow-up. Laparoscopic ventral hernia repair (LVHR) is a well recognized minimally invasive surgical technique for repair of different types of abdominal wall ventral hernias. However, the best method of mesh fixation during LVHR is still a subject ofdebate.?Patients & Methods: In the present study, 50 patients were presented with ventral hernia between June 2012 and October 2013. Demographics of the patients were recorded. All patients were submitted to LVHR with mesh fixation by “Double Crown” of tackers. The first crown was placed on the mesh periphery with 1 cm between each 2 successive tackers and the second crown around the edges of the defect. Operative complications, VAS scale, post-operative complications, and length of hospital stay were reported. Results: The mean age was 40.08 years. Female to male ratio was 3:2. The mean BMI was 32.3. The diameter of the hernial defect was <5 cm in 64%, while, the defects larger than 15 cm were excluded. LVHR was successfully completed in all the patients with no conversion. Only 1 patient had intra-operative bleeding from omental vessels that was successfully controlled. The mean operative time was 79 minutes. Post-operatively, the mean VAS was 3.96, 2.12, and 0.24 at 24 hours, 2 weeks, and 4 weeks, respectively. Two patients developed post-operative ileus that was treated conservatively and 1 patient developed persistent seroma that was treated by repeated aspiration. The mean length of hospital stay was 3.08 days. Conclusion: “Double Crown” tackers mesh fixation in LVHR seems to be a safe and effective surgical technique with favorable outcome. However, further randomized studies are needed on larger numbers of patients to validate these results.

Surgical Science (SS) , 2017, DOI: 10.4236/ss.2017.88037
Abstract: Background: Laparoscopic distal gastrectomy (LDG) for gastric adenocarcinoma (GA) is gaining more acceptances worldwide. Its results are still controversial. This study aimed to assess short term outcomes of LDG and compare it to the standard open distal gastrectomy. Patients and Methods: 27 patients with GA of the distal 2/3 of the stomach were included and divided into 2 groups; Group A: 15 patients submitted to open distal gastrectomy with D2 lymph node (LN) dissection, and Group B: 12 patients submitted to LDG with D2 LN dissection. Results: The median age was 54 and 54.3 years in group A and B respectively. The median operative time was 118.7 and 210.2 minutes in group A and B respectively. The median safety margin was 6.52 and 5.7 cm in group A and B respectively while the median number of excised LN was 24.2 and 21.4 in group A and B respectively. One patient in group B had intraoperative bleeding that was controlled laparoscopically. No conversion to open surgery needed in group B. The median number of narcotic doses was 5.9 and 4.25 in group A and B respectively. The median length of hospital stay was 7.2 days in group A and 7.3 days in group B. Three patients in group A and 2 patients in group B had postoperative complications and all were treated successfully conservatively. Conclusion: LDG with D2 LN dissection is oncologically safe with short-term outcomes comparable to those of the open surgery. Gaining more surgeons’ experience is necessary to improve these results.

Open Journal of Anesthesiology (OJAnes) , 2018, DOI: 10.4236/ojanes.2018.810026
Abstract: Background: OSA affects up to quarter of general population. It is associated with morbid obesity with a higher morbidity and mortality rates. STOP Bang questionnaire is a validated method for OSA screening. OSA patients are at high risk of developing airway obstruction, cardiac events, congestive heart failure, stroke and desaturation post operatively. The aim of this study is to evaluate adverse respiratory events in patients undergoing bariatric surgery in relation to risk of OSA using Stop Bang questionnaire. Methods: This prospective double cohort study was conducted in Tanta University Hospital from Marchto August 2017. During the preoperative assessment, STOP-BANG questionnaire was performed. After extubation, patients were transferred to PACU unit. Respiratory complications were assessed thereafter. Based on STOP-BANG score, patients were divided into two groups, high risk of OSA with STOP-BANG > 3 (Group I) and low risk of OSA with STOP-BANG < 3 (Group II). Results: 104 patients were included in this study. Group I had more comorbidities in the form of CAD (15% versus 2%, P < 0.001), dyslipidemia (28% versus 11%, P < 0.001) and diabetes on insulin treatment (38% versus 6%, P > 0.001). Higher number of respiratory complications was noted in high-risk group (31 patients, 59%) compared to (24 patients, 46%) in group II yet, it was not significant. Conclusion: Obese patients with STOP-BANG score > 3 undergoing bariatric surgery are associated with hypertension, dyslipidemia, CAD, and renal insufficiency. High-risk OSA obese patients are at higher risk of developing respiratory compilations like inability to breathe deeply and hypoxia in postoperatively.

Open Journal of Gastroenterology (OJGas) , 2014, DOI: 10.4236/ojgas.2014.47041
Abstract: The fine structure of the crypt epithelium of the duodenal mucosa in albino rats was studied to represent the types and distribution of the basal-granulated or endocrine cells. Twenty male animals were used. Perfusion-fixation was made and samples of duodenal mucosa were taken and processed to prepare epon-embedded specimens for examination by a transmission electron microscope. Cells containing membrane-bound granules were seen in the crypt epithelium. They were identified to be basal-granulated cells. Six different types of such cells were demonstrated. All of the cells were of the closed type. The possible functional significance of these closed cell types was discussed. Correlation among the distributions of such cells in the intestine of albino rat might enable the physiologists, internists and other research workers to study several biologically active peptides with well-established functions other than those which have long been investigated.

Forensic Medicine and Anatomy Research (FMAR) , 2018, DOI: 10.4236/fmar.2018.62002
Abstract: Background: Green tea intake is accompanied with a lower incidence of cardiovascular disease, cancer and neurodegenerative disorders; hence green tea extract has been included as dietary supplement along with other supplements and multivitamins. Aim of the Work: Studying the effect of cyclophosphamide administration on the liver of adult male albino rats and the possible protective role of green tea extract. Material and Methods: The current study was carried out on 45 adult male albino rats. They were divided into three equal groups (each included 15 rats). Group I (control group) was injected intraperitoneally with normal saline at a dosage of 0.5 mg/kg body weight twice weekly for 9 weeks. Group II was injected intraperitoneally with cyclophosphamide (CP) (150 mg/kg/day) for two weeks. Group III: rats received green tea extracts orally (50 mg/kg/day) for three weeks, and then continued for further two weeks concomitantly with intraperitoneally cyclophosphamide (CP) injected (150 mg/kg/day). Results: Rats exposed to cyclophosphamide (CP) showed several histological and histochemical changes in their liver. These changes were improved by using green tea. Conclusion: The present work showed that green tea had preventive and therapeutic effect upon livers of albino rats after they were exposed to CP.

Surgical Science (SS) , 2015, DOI: 10.4236/ss.2015.62014
Abstract:

Background:?Perforated peptic ulcer is a common surgical emergency. The classic treatment is the mid-line laparotomy. However, laparoscopic treatment has been shown to be reliable. Few studies have evaluated its overall utility. The aim of this study is to assess the efficacy of laparoscopic repair of perforated duodenal ulcer.?Patients and Methods:?This study included 50 patients presented by perforated peptic ulcer between July 2009 and August 2014. They were submitted to laparoscopic omental patch repair with thorough peritoneal wash. Patients’ demographics, diagnostic techniques, management and outcome were evaluated. Results:The mean age was 38.6 years with male to female ratio being 1.6:1. The perforation was diagnosed by plain X-ray abdomen in erect position in 43 patients and by abdominal CT scan in 7 patients. The laparoscopic repair of the perforation was successful in 48 patients while in 2 patients mid-line laparotomy was needed for proper control of the severe intra-abdominal sepsis. Post-operatively, all patients tolerated soft diet on the 3rd?post-operative day and full diet on the 4th?post-operative day. The mean duration of hospital stay was 4.5 days. Two patients developed post-operative intra-abdominal collection that was treated by ultrasound guided drainage, three patients developed umbilical port site wound infection while only two patients developed leakage, one of them reoperated after failed conservative surgery. No mortality was encountered in the study. Conclusion:?Laparoscopic repair of perforated peptic ulcer is a safe and reliable technique with accepted morbidity and mortality rates with all the advantages of the minimally invasive surgery.

Positioning with Wide-Area GNSS Networks: Concept and Application  [PDF]

Positioning (POS) , 2012, DOI: 10.4236/pos.2012.31001
Abstract: The use of Global Navigation Satellite Systems (GNSS) for positioning has revolutionized the way location data is be- ing collected. The NAVigation System with Time And Ranging Global Positioning System (GPS), which is a principal component of the global navigation satellite system (GNSS); is a satellite-based radio navigation system that provides positions of points of interest and time information to users. GPS positional accuracy can be improved by using differential corrections obtained through a technique called Differential GPS (DGPS), which is known to provide the most accurate positioning results. Differential correction can be applied in real time at the data collection phase or in the of- fice, at the post-processing phase. DGPS is generally used for positioning purposes through static or kinematics GPS surveys. In static GPS surveys, one receiver is placed at a point whose coordinates are known and the other receiver is placed over a point whose coordinates are desired. In kinematic surveys, one receiver remains at one point (base station) normally with known coordinates, and the other receiver (rover) moves from point to point in the project area. Kinematic surveys in which points positions are computed on-the-fly (OTF) are known as real-time kinematic (RTK). RTK surveys provide real-time locations of points of interest needed in many applications. Positioning with wide-area GNSS networks is basically based on the DGPS and RTK concepts. Observables from a network of a finite number of GPS receivers over an area are processed by a server at a central location (network server) and made available to the users of the network later or in real-time through radio-based, satellite, or wireless communications. This article provides a review of the concept and application of positioning with wide-area GNSS networks.
