Histopathological Patterns and Characteristics of Abnormal Cervical Smear in Madinah Region of Saudi Arabia 下载免费PDF全文

Cervical cancer is a major public health problem that continues to be one of the leading female genital cancersworldwide. In the kingdom of Saudi Arabia (KSA), cervical cancer ranks the fifteenth most frequent cancer amongfemales. This study is the first published research study addressing the screening of cervical cancer in Madinah regionof KSA. Aim: To evaluate the abnormal cytological entities detected by cervical Pap smear in Madinah region of KSAand to compare the results with other national and international studies. Methods: This retrospective case-control studywas conducted in the Departments of Obstetrics and Gynecology, and Histopathology at the Maternity and ChildrenHospital (MCH), Madinah, KSA from January 2013 to December 2015. Results: Of the 1594 cases reviewed, only38 cases (2.4%) had epithelial cell abnormalities. High grade squamous intraepithelial lesions (HSIL) and low gradesquamous intraepithelial lesions (LSIL) were the most common diagnosis categories, and cervical cancer accountedfor 36.8% of the total cases for each, followed by atypical squamous cells of uncertain significance (ASCUS) foundin (15.9%). Squamous cell carcinoma (SCC ) was found in (5.3%) of the cases. Patients with abnormal epithelialchanges had higher parity (P=0.021) and presented more with a complaint of postcoital bleeding (P<0.0001), tend tohave abnormal cervical appearance (P=0.004), more likely bleeding on touch (P=0.001) and associated with cervicalerosion (P=0.014). Conclusion: The study showed a relatively low prevalence of epithelial cell lesions. These lesionswere mainly squamous cell lesions harbored by females who have an abnormal cervical appearance, and those withhigh parity who were lacking cervical screening program. 相似文献

BackgroundSurgical techniques for fixation of the testis are varied and subject to ongoing debate. Non-sutured techniques may avoid the theoretical morbidities of sutured fixation of the testis yet are criticized for insufficient prophylaxis against future torsion. This study aims to compare outcomes between sutured (point-fixation) versus Jaboulay fixation.MethodsEmergency scrotal explorations performed at a tertiary hospital in the state of South Australia between February 2002 and December 2017 were analyzed to identify cases of testicular torsion. Primary outcome measures included future testicular torsions and return to theater episodes following initial testicular fixation. Secondary outcome measures included re-presentations and post-operative complications.ResultsA total of 482 scrotal compartments were explored in 244 boys with acute testicular torsion. Testis fixation was performed using sutured point-fixation in 58.4% and Jaboulay tunica plication in 41.6%. No future testicular torsion occurred regardless of fixation technique. There were no significant differences in returns to theater (0.4% versus 1.2%, p = 0.12), re-presentations (6.9% versus 6.0%, p = 0.83), and post-operative complications (1.7% versus 1.8%, p = 1.0) in testes that previously underwent sutured or Jaboulay fixation, respectively.ConclusionJaboulay testicular fixation techniques are comparable with sutured point-fixation techniques in effectiveness and morbidity.Type of StudyTreatment Study.Level of EvidenceLevel III. 相似文献

IntroductionTesticular prosthesis implantation may be used for neoscrotal augmentation in transgender men.AimAssess the clinical outcomes and risk factors for postoperative complications of this procedure in transgender men.MethodsAll transgender men who underwent neoscrotal augmentation with testicular implants between January 1992 and December 2018 were retrospectively identified. A retrospective chart study was performed that recorded surgical characteristics and postoperative complications. Risk factors on complications were identified using uni- and multivariate analyses.Main Outcome MeasureSurgical outcomes included explantation due to infection, extrusion, discomfort, or leakage.ResultsWe identified 206 patients, and the following prostheses were placed: Dow Corning (n = 22), Eurosilicone (n = 2), Nagor (n = 205), Polytech (n = 10), Promedon (n = 105) , Prometel (n = 22), Sebbin (n = 44), and unknown (n = 2). The mean clinical follow-up time was 11.5 ± 8.3 years. In 43 patients (20.8%), one or both prostheses were explanted due to infection, extrusion, discomfort, prosthesis leakage, or urethral problems. Currently, scrotoplasty according to Hoebeke is the most frequently performed technique. Our review found that for this technique explantation occurred in 6 of 52 patients (11.5%). A history of smoking was a risk factor for postoperative infections and prosthesis explantation. In earlier years, larger prostheses were immediately placed at scrotal reconstruction; however, a trend can be seen toward smaller and lighter testicular prostheses and delayed implantation.Clinical ImplicationsPatients wanting to undergo this procedure can be adequately informed on postoperative outcomes.Strengths & LimitationsStrengths of this study include the number of patients, long clinical follow-up time, and completeness of data. Weaknesses of this study include its retrospective nature and the high variability of prostheses and surgical techniques used.ConclusionOver the years, scrotoplasty techniques and testicular prostheses preferences have changed. Explantation rates have dropped over the last decade.Pigot GLS, Al-Tamimi M, Ronkes B, et al. Surgical Outcomes of Neoscrotal Augmentation with Testicular Prostheses in Transgender Men.

Health Literacy,Knowledge on Cervical Cancer and Pap Smear and Its Influence on Pre-Marital Malay Muslim Women Attitude towards Pap Smear 下载免费PDF全文

Background: Cervical cancer is preventable. In Malaysia, women are found to have good awareness of the disease and yet, the Pap smear uptake is still poor. Measuring health literacy level could explain this discrepancy. This study aims to determine the relationship between health literacy, level of knowledge of cervical cancer and Pap smear with attitude towards Pap smear among women attending pre-marital course. Methods: A cross sectional study was performed in three randomly selected centres that organised pre-marital courses. All Malay Muslim women participants aged 18 to 40 years old were recruited while non-Malaysian, illiterate, and had hysterectomy were excluded. Validated self-administered questionnaires used were European Health Literacy Questionnaire (HLS-EU-Q16 Malay) and Knowledge and attitude towards Cervical Cancer and Pap Smear Questionnaire. The mean percentage score (mean± SD) was calculated, with higher scores showed better outcomes. Multiple linear regression was used to measure the relationship of independent variables with attitude towards Pap smear. Results: A total of 417 participants were recruited with a mean age of 24.9 ± 3.56 years old. Prevalence of awareness of cervical cancer was 91.6% (n=382, 95% CI: 89.0%, 94.2%) and mean percentage score was 74.7%±7.6. Prevalence of awareness of Pap smear was 59.0% (n=246, 95% CI: 54.2%, 63.8%) and mean percentage score was 80.2% ± 6.5. The health literacy mean score was 13.3±3.6, with minimum score 0 and maximum score 16. The mean percentage score of attitudes towards Pap smear was 64.8%±9.3. Multiple linear regression analysis demonstrated significant relationship between health literacy (p=0.047) and knowledge of Pap smear (p<0.001) with attitude towards Pap smear. Conclusion: A higher health literacy with high knowledge of Pap smear improves the attitude towards Pap smear. Pre-marital course is an opportunistic platform to disseminate information to improve health literacy and knowledge of cervical cancer and Pap smear screening. 相似文献
