Objective: Papanicolou (Pap) smear screening has dramatically reduced the incidence of invasive cervical cancer worldwide. Pap smear screening is still not widely available in developing countries and therefore cannot be used as mass screening tool. This study was designed to establish the role of Pap smear as a routine investigation for females presented to gynecological department. Methods: It was a hospital based study. Patients attending with complaints including irregular vaginal bleeding, vagina discharge, dyspareunia, low backache or lower abdominal pain and primary or secondary infertility were included in the study. All these patients underwent pap smear. results: Age of females was 25 to 60 years. Ninety females had dysplasia. Mild to moderate dysplasia was positive in 84 females. Six patients had severe dysplasia suspicious for squamous cell carcinoma (SCC) which was confirmed as invasive SCC on biopsy. All patients with mild to moderate dysplasia were regularly followed at 4 to 6 months. Thirty patients were lost during follow up. Forty had negative smear at 6 months, while fourteen having persistent dysplasia on repeated pap smears were referred for biopsies. Histopathology confirmed invasive SCC in five patients while chronic cervicitis was reported in nine patients. Only two of screened patients with high suspicion for cancer showed false negative results. Directed biopsies done in these confirmed invasive SCC. Conclusion: Pap smear is a useful, simple, non-invasive and reliable screening tool for cervical cancer. It may be practiced as a routine investigation in outpatients in developing countries, where mass screening is not available.

创新是什么?有时候创新和创造是不同的,在我看来,创新就是应用新的主意而不是产生新的主意,这就是创新和创造的不同之处。那么,应用新的想法和新的主意的目的是什么呢?一般而言,对新想法新主意的应用是为了提升效率、推动经济,是为了改善人们的生活,带来更多的经济效益。但是在我看来,今后的创新不仅仅是为了盈利,我们一个重要的目标是可持续性,也就是说,要把盈利和可持续结合起来。在很多领域都可以创新,比如政策创新、商业创新等。技术创新是我们最经常谈到的,就是要应用科学技术的原则或想法来开发更高效的、更具有经济性的产品或者流程。

Aim: Graft vessel disease (GVD) is one of the main limiting factors to long-t erm survival after adult heart transplantation (HTx). The incidence of epicardia l and microvascular GVD in paediatric patients was studied. Methods: A total of 137 coronary angiographies from 130 paediatric HTx and heart and lung transplant (HLTx) patients (70 male, 60 female, aged 0-18 y) were evaluated according to the Stanford classification and its supplements (minor vessel alterations). In H &E stainings from right ventricular endomyocardial biopsies (EMB = 397), light microscopic diagnosis of acute cellular rejection (ISHLT classification) and vas cular reaction (morphology of endothelial cells and vessel walls) was performed. results: Moderate rejection was present in 32.8%and severe rejection in 13.3 %of EMB. Microvascular EC swelling was found in 33.5%and vessel wall thickeni ng in 53.8%of EMB. The results of the coronary angiographic investigations wer e: Stanford lesions = 61.2%, peripheral obliterations = 52.5%, diameter fluc tuations = 86.3%, pathologic tapering = 64.0%, calcifications = 10.8%. Lon g-term survivors (≥5 y) showed macrovascular alterations in 78%of cases and m icrovascular alterations in 67%of cases. Conclusion: The development of micro- and macrovascular GVD is one of the predominant complications in long-term surv ivors after paediatric HTx and HLTx.

DNA Barcoding of Insects and Its Direct Application for Plant Protection

Open Journal of Applied Sciences 2024年第3期14卷 676-686页

The introduction of invasive insect pests across national borders has become a major concern in crop production. Accordingly, national plant protection organizations are challenge to reinforce their monitoring strategies, which are hampered by the weight and size of inspection equipment, as well as the taxonomic extensiveness of interrupted species. Moreover, some insect pests that impede farmer productivity and profitability are difficult for researchers to address on time due to a lack of appropriate plant protection measures. Farmers’ reliance on synthetic pesticides and biocontrol agents has resulted in major economic and environmental ramifications. DNA barcoding is a novel technology that has the potential to improve Integrated Pest Management decision-making, which is dependent on the ability to correctly identify pest and beneficial organisms. This is due to some natural traits such as phenology or pesticide susceptibility browbeaten by IPM strategies to avert pest establishment. Specifically, Deoxyribonucleic acid (DNA) sequence information was applied effectively for the identification of some micro-organisms. This technology, DNA barcoding, allows for the identification of insect species by using short, standardized gene sequences. DNA barcoding is basically based on repeatable and accessible technique that allows for the mechanisation or automation of species discrimination. This technique bridges the taxonomic bio-security gap and meets the International Plant Protection Convention diagnostic standards for insect identification. This review therefore discusses DNA barcoding as a technique for insect pests’ identification and its potential application for crop protection.

Background: The risk of CKD is high in Saudi Arabia due to increasingly growing prevalence of its risk factors, such as diabetes, hypertension and obesity. Therefore, the objective of this study was to assess the level of awareness of Saudi population towards CKD risk factors in order to generate platform for future planning. Methodology: This study included 940 apparently healthy Saudi volunteers, their ages ranging from 17 to 65 years old with a mean age of 35 years. A purposeful questionnaire was designed and used for obtaining data about the CKD risk factors. results: Out of 940 participants, 293 (31.2%) were males and 647 (68.8%) were females, giving males “females” ratio of 1.00:2.21. About 62.3% of the participants were found to believe that DM is one of the main risk factors for CKD, of whom, 74% were males and 57% were females. Approximately 60% of the participants were found believing that hypertension is one of the main risk factors for CKD, of whom 79.5% were males and 51.6% were females. Conclusion: There is an increasing in the prevalence of CKD risk factors among Saudi population. Although, the levels of awareness toward some CKD risk factors are relatively increasing, but more health education efforts are deemed importance.

In this review article, various preferences in breast plastic surgery particularly after breast cancer will be discussed in view of the diverse indications for the different construction procedures. The various conditions that necessitate the need for reconstruction are appraised, the important reconstructive procedures are discussed. The most important indications procedures discussed in this review include;Prophylactic subcutaneous mastectomy, Lumpectomy and radiation, Modified Mastectomy with Axillary Sampling, Nipple reconstruction, and the contralateral breast. These procedures are discussed in view of plastic surgeon practice and patients acceptability in Saudi Arabia. Data from Saudi Arabia in particular was identified through searches of the EMBASE, and MEDLINE database, using the keywords: Saudi Arabia, breast plastic Surgery, breast reconstruction, autologous breast reconstruction, breast augmentation. Advances in prosthetic technologies and modifications in autologous flap techniques, and the development of novel tissue alternatives have allowed for sustained developments in breast reconstruction results. A variety of attitudes has been accessible for addressing the difficulties that endure after resection of breast cancer in Saudi Arabia. Patients should be educated to accept different process in this context.

Background: Increasing awareness level and health education can reduce the burden of Chronic Kidney Disease (CKD) at community base. Therefore, the aim of the present study was to assess the level of knowledge towards CKD manifestations in Saudi Arabia. Methodology: This is a descriptive prospective study including 900 apparently health Saudi volunteers, their ages ranging from 18 to 65 years old with a mean age of 34 years. A purposeful questionnaire was deliberated and used for obtaining data about the CKD. results: Out of 900 contributors, 268 (29.8%) were males and 632 (70.2%) were females, giving males:females ratio of 1.00:2.36. About 102/900 (11.3%) of the participants (all of them were females) were found to believe that CKD has no specific symptoms. Conclusion: The awareness towards CKD manifestation is relatively low, which necessitates the important of community based intervention including health educational programs.
