Introduction and Research Problem: Breast cancer is the most common of all female cancers in Kingdom of Saudi Arabia. Different studies conducted in the Kingdom have shown that knowledge of females regarding breast cancer is poor. Aim of the study was to determine knowledge, attitude and practice among students of Saudi female medical university towards Breast Self Examination (BSE) and also to explore their knowledge about breast cancer. Research Methodology: An observational cross-sectional study was conducted at Faculty of Medicine, Taif University during October 2013. Sample size was 378 with mean age of 19.9 ± 1.5. A self administrated questionnaire was used to obtain data about knowledge, attitude and practice towards BSE and knowledge about breast cancer. Data were collected and fed to SPSS version 16. Shape of distribution for numerical data was tested by using one sample Kolmogorov-Smirnov test. Chi-Square Test & Fissure Exact Test (FET) were used for testing relation between categorical variables while correlation analysis was used to test the strength of relation between numeric variables. Main Results: The study revealed that only 8.2% of participants had good overall knowledge about breast cancer and BSE. Although 66% of the study sample had positive attitude towards BSE, only 17% reported that they practiced BSE monthly. A significant positive moderate correlation was found between overall knowledge score and attitude towards BSE (r = 0.449 & p = 0.000). The same was for the frequency of BSE practice but it was found to be in a weak magnitude (r = 0.223 & p = 0.000). Conclusion and Recommendations: Although there was lack of knowledge about breast cancer and BSE yet, positive attitude towards BSE was encouraging. Most female medical students in our sample did not perform BSE or perform it irregularly. Therefore, more intensified awareness programs among students of medical university are necessary to keep in view their current status of breast cancer a

Objective: This study aims at assessing the relation between smoking and the incidence of haematoma formation in abdominoplasty surgery cases. Patients and Methods: This is a 4 years retrospective study involving the patients who underwent abdominoplasty surgery between the period of May 2015 and April 2019 in Zayed Military Hospital, Abu Dhabi, United Arab of Emirates. The incidence of haematoma formation was assessed in relation to tobacco use in these patients. Results: 164 patients met the inclusion criteria of the study. 35 patients were smokers (21.3%) and 129 patients were non-smokers (78.7%). The mean age was 38.4 (21 - 59 years). The mean BMI was 27 kg/m2 (21.4 - 34.7 kg/m2) and the mean hospital stay was 6.5 days (4 - 19). 23 patients in the study developed haematoma (14%). 11 of them had surgical evacuation of the haematoma (6.7%) while the rest were aspirated in the out-patient clinic. Out of the 23 patients who developed haematoma, 17 patients were smokers and 6 were non-smokers. The incidence of haematoma among smokers was 48.6% (17 out of 35 cases) while its incidence among nonsmokers was 4.7% (6 out of 129 cases) showing a clear relationship between smoking and hematoma formation (p Conclusion: Our study shows a direct relationship between smoking and haematoma formation in abdominoplasty cases. Cessation of smoking during the perioperative period is required before embarking on such a procedure.

Background: The robustness is a measurement of an analytical chemical method and its ability to contain unaffected by little with deliberate variation of analytical chemical method parameters. The analytical chemical method variation parameters are based on pH variability of buffer solution of mobile phase, organic ratio composition changes, stationary phase (column) manufacture, brand name and lot number variation;flow rate variation and temperature variation of chromatographic system. The analytical chemical method for assay of Atropine Sulfate conducted for robustness evaluation. The typical variation considered for mobile phase organic ratio change, change of pH, change of temperature, change of flow rate, change of column etc. Purpose: The aim of this study is to develop a cost effective, short run time and robust analytical chemical method for the assay quantification of Atropine in Pharmaceutical Ophthalmic Solution. This will help to make analytical decisions quickly for research and development scientists as well as will help with quality control product release for patient consumption. This analytical method will help to meet the market demand through quick quality control test of Atropine Ophthalmic Solution and it is very easy for maintaining (GDP) good documentation practices within the shortest period of time. Method: HPLC method has been selected for developing superior method to Compendial method. Both the compendial HPLC method and developed HPLC method was run into the same HPLC system to prove the superiority of developed method. Sensitivity, precision, reproducibility, accuracy parameters were considered for superiority of method. Mobile phase ratio change, pH of buffer solution, change of stationary phase temperature, change of flow rate and change of column were taken into consideration for robustness study of the developed method. Results: The limit of quantitation (LOQ) of developed method was much low than the compendial method. The % RSD fo

Hemangiopericytoma is a rare vascular tumour of infants. Although generally considered to be benign, local recurrence and metastases can occur. Herein, we report on two full term girls, delivered with lumbosacral swelling and left thigh swelling respectively. Complete surgical excision with safety margins was performed for each lesion. Histologic examination of both lesions showed picture of infantile hemangiopericytoma. There is no evidence of local recurrence or distant metastasis during last 20 and 17 months for 1st case and 2nd case respectively. In conclusion;most infantile hemangiopericytoma follow a benign course. Rarely these tumours behave aggressively with local infiltration, recurrences and even distant metastases. Careful follow up is therefore essential.

Background: Postpartum depression is the most common psychological health problem among females;it begins after the birth of the child and can occur at any time during the first year of delivery. The COVID-19 pandemic is a novel virus that is highly infectious and has several negative psychological impacts on individuals globally. Aim: Coronavirus disease 2019 (COVID-19) has been reported to increase the incidence rate of depression. We investigated the prevalence rate and associated factors of postpartum depression (PPD) among women in Jeddah, Saudi Arabia, during the COVID-19 period, thereby attempting to determine whether and how COVID-19 affected PPD. Methods: This is a cross-sectional study that was conducted on women at one week to six months postpartum using an online questionnaire. SPSS program was used for analyzing data. Results: This study included 150 participated women;49.3% were in the age range of 25 - 34 years old. There were 30.7% reported being primigravida. Regarding the level of depression, there were 60.7% reported the presence of depression;the depression was affected by some demographics of females such as the education level (P = 0.021) and other factors related to the COVID-19 pandemic such as visiting the doctor during

引言在近二十年来牵引电机的比容量(kW/kg)几乎增加了一倍,这是由于发展和使用新的绝缘提高了绕组的温度,以及采用较高耐热等级绝缘的结果。如今,除了牵引电机一直根据IEC309文件采用H级绝缘外,F级(TI—155℃)绝缘是发电机和用电设备的共同特点。因此限定定子绕组铜温度为220℃而转子为200℃,这个技术条件对这些电机比容量的提高到0.3千伏/公斤是可靠的,但人们仍希望进一步提高其比特性以便从同样结构尺寸能得到更大的出力。

笔者选取了北京郊区5个农业沼气工程,从原料特性、产气潜能、厌氧污泥活性以及发酵池p H值稳定性等几个方面探讨农业沼气工程的发酵效率评估。通过测试原料的元素组成,开展产甲烷潜能和产甲烷活性实验,建立了不同原料的发酵化学计量学方程,获得了不同原料的产气率、产气速率和发酵池污泥的乙酸比产甲烷活性(SMA2000)。分析结果表明:养殖废物的进料浓度较理想,适合高浓度厌氧发酵工艺。鸡粪原料的产气率较高(200 m LCH4·g-1COD),但C/N比较低9.6∶1,发酵池的氨氮浓度6.0 g·L-1,有明显的产气迟滞期。秸秆高温发酵的产气率达到162 m LCH4·g-1COD,产气速率高于牛粪和猪粪中温发酵,发酵池污泥的p H值为7.1。猪粪与牛粪沼气工程的发酵效率低于鸡粪和秸秆沼气,但具有良好的稳定性。在农业废物沼气工程中,须根据物料特性合理的选择工艺条件。
