RESUMO

Type 1 diabetes mellitus (T1DM) is an endocrine disorder in which pancreatic ß cells stop producing insulin, typically due to autoimmune destruction. This results in hyperglycemia and ketosis; thus, insulin replacement is vital to management. Incidence peaks in puberty and early adulthood, but onset can occur at any age. However, prevalence is highest among adults because persons with T1DM live for many years. Symptoms include polyuria, polydipsia, and weight loss. Acute complications include diabetic ketoacidosis, which requires urgent management. Long-term complications include microvascular and macrovascular disease. Patients with T1DM are at higher risk for other autoimmune diseases and psychosocial issues. Management should focus on optimizing glucose control to reduce acute and long-term complications.

RESUMO

Objectives: To evaluate and compare the Ondansetron and Granisetron in preventing spinal anaesthesia induced hemodynamic instability in obstetric patients. Methods: The comparative analytical study was conducted at Combined Military Hospital, Rawalpindi, from September to October, 2021. One hundred and twenty pregnant women undergoing cesarean section, were enrolled in the study via non probability convenience sampling, and divided into three groups containing 40 participants each based on the type of antiemetic premedication they received, if any: Group N were those not requiring antiemetic premedication, Group O consisted of those given ondansetron 4mg, and Group G had those receiving 3mg granisetron, 15 minutes prior to administration of spinal anaesthesia. Systolic blood pressures and heart rates were recorded before and at multiple intervals after spinal anaesthesia was administered. Episodes of hypotension and bradycardia were recorded. Requirement of phenylephrine and atropine as rescue drugs was recorded for each participant. Results: There was a statistically significant difference in incidence of hypotension among the three groups (p value <0.001), with both drugs being superior to the control group (p value <0.001 for both), and 3mg granisetron being superior to 4mg ondansetron (p value <0.001). As for incidence of bradycardia, ondansetron and granisetron were superior to control group (p value 0.03 and <0.001 respectively), but there was no significant difference between the two drug groups (p value 0.094). Conclusion: High dose granisetron (3mg) is superior to low dose ondansetron (4mg) in preventing hemodynamic fluctuations induced by spinal anaesthesia.

RESUMO

BACKGROUND: Women with human immunodeficiency virus have higher rates of abnormal cervical and vaginal cytology and, subsequently, of cervical and vaginal cancers. Although professional bodies currently advocate for indefinite cytology screening for women living with human immunodeficiency virus, these recommendations are based on expert opinion, not evidence-based. In the general population, women who have never had an abnormal cytology result can cease screening at age 65 years. This is due to the relatively low incidence of dysplasia in this group and the risk of false-positive results as women age, invasive follow-up testing, and destructive treatments of lesions that are unlikely to progress to cancer. What is unclear, however, is how human immunodeficiency virus-infected women over age 65 years who have no history of abnormal cytology should be screened to maximize benefit while reducing harms of overscreening. This is a crucial question, as women over age 65 years who are living with human immunodeficiency virus comprise a rapidly growing population. OBJECTIVE: To describe the incidence of abnormal cervical and vaginal cytology results in women over the age of 65 years living with human immunodeficiency virus, with the goal of providing evidence for screening recommendations. MATERIALS AND METHODS: A retrospective chart review was performed, identifying 69 women who received gynecologic follow-up in a county hospital system in Houston, Texas, between 2000 and 2018 and who met study criteria. Incidence of abnormal cytology after age 65 was determined by analyzing all available cytology results after age 65. Demographic and clinical risk factors, including human immunodeficiency virus-specific clinical risk factors, were analyzed. Matched cervical and vaginal pathology results, if conducted, were also evaluated. Statistical analyses were conducted using Stata 15, including χ2 tests and Wilcoxon rank-sum tests for categorical and continuous variables, respectively. Estimates of the cumulative probability of developing an abnormal cytology result was calculated using the Kaplan-Meier method. RESULTS: Among 69 women with no history of abnormal cervical cytology, 12 (17%) went on to develop abnormal cytology results, including 3 (4%) showing high-grade squamous intraepithelial lesions. The incidence rate was 3.5 cases per 100 woman-years (95% confidence interval, 1.58, 7.81). No demographic or gynecologic characteristics were associated with abnormal cytology. A CD4 count of <200 at the time of human immunodeficiency virus diagnosis or at the time of cytology was associated with an abnormal Papanicolaou test result (P < .0001, P = .031). Of women with pathology results in the county hospital system (n = 8), 4 (50%) had cervical intraepithelial neoplasia 2+ or vaginal intraepithelial neoplasia 2+. No women developed invasive cancer. However, 50% of women who had an abnormal Papanicolaou test result in the study period were lost to follow-up; outcomes for these patients are unknown. CONCLUSION: Given the relatively high proportion (4%) of women with high-grade squamous intraepithelial lesions/cervical intraepithelial neoplasia 2+/vaginal intraepithelial neoplasia 2+ during the study period, we agree with current screening recommendations for continued routine Papanicolaou testing after the age of 65 years in women with human immunodeficiency virus. More evidence from larger studies is needed to solidify evidence-based screening recommendations in this unique and growing population.

RESUMO

Infertility rate documented in Pakistan is 21.9% with only 25% success rate even after procedures like intracytoplasmic sperm injection (ICSI). This rate is further on the decline with enhancement of female age. We aimed to observe the effect of female age on oocyte parameters and reproductive outcome after ICSI. It was done by retrospective analysis of a quasi- experimental design carried out after approval from "Ethical review board of Islamabad clinic serving infertile couples" from July 2010 to August 2011. The response to ovarian stimulation in (282) females was assessed on the basis of groups, A, B, C and D with age ranges up to 25years; 25.1 to 30years; 30.1 to 35years and >35years, respectively. The outcome was assessed as non-pregnant, preclinical abortion and clinical pregnancy groups on the basis of beta hCG and cardiac activity by trans-vaginal scan. We observed that maximum number of pregnancies 32 (38%) occurred in C group, and least 10 (10%) in group A. There was a statistical reduction in the number of mature and fertilized oocytes as the age advanced from group C to D (p<0.05).This shows that reduction in maturity and fertilization of oocytes with advancement of age recommends early referral of couples to assisted reproductive clinics.

RESUMO

Neutralization of bacterial cell surface potential using nanoscale materials is an effective strategy to alter membrane permeability, cytoplasmic leakage, and ultimate cell death. In the present study, an attempt was made to prepare biogenic silver nanoparticles using biomolecules from the aqueous rhizome extract of Coptis Chinensis. The biosynthesized silver nanoparticles were surface modified with chitosan biopolymer. The prepared silver nanoparticles and chitosan modified silver nanoparticles were cubic crystalline structures (XRD) with an average particle size of 15 and 20 nm respectively (TEM, DLS). The biosynthesized silver nanoparticles were surface stabilized by polyphenolic compounds (FTIR). Coptis Chinensis mediated silver nanoparticles displayed significant activity against E. coli and Bacillus subtilus with a zone of inhibition 12 ± 1.2 (MIC = 25 µg/mL) and 18 ± 1.6 mm (MIC = 12.50 µg/mL) respectively. The bactericidal efficacy of these nanoparticles was considerably increased upon surface modification with chitosan biopolymer. The chitosan modified biogenic silver nanoparticles exhibited promising activity against E. coli (MIC = 6.25 µg/mL) and Bacillus subtilus (MIC = 12.50 µg/mL). Our results indicated that the chitosan modified silver nanoparticles were promising agents in damaging bacterial membrane potential and induction of high level of intracellular reactive oxygen species (ROS). In addition, these nanoparticles were observed to induce the release of the high level of cytoplasmic materials especially protein and nucleic acids into the media. All these findings suggest that the chitosan functionalized silver nanoparticles are efficient agents in disrupting bacterial membrane and induction of ROS leading to cytoplasmic leakage and cell death. These findings further conclude that the bacterial-nanoparticles surface potential modulation is an effective strategy in enhancing the antibacterial potency of silver nanoparticles.

RESUMO

Colorectal cancer (CRC) is one of the leading causes of cancer deaths around the globe. Bioactive food ingredients such as prebiotics have protective potential in colon cancer. Data on galacto-oligosaccharides (GalOS) against CRC are very limited and GalOS used in this study have ß-1,6 and ß-1,3 as major glycosidic linkages and, to our best knowledge, were never used before against any cancer treatment. This study aims to investigate the protective role of novel GalOS against various biomarkers of CRC including aberrant crypt foci (ACF), bacterial enzymes and short chain fatty acids (SCFA) in a rodent model induced with 1,2-dimethylhydrazine dihydrochloride (DMH). Inulin group was taken as positive control in present study to compare novel GalOS protective effects. GalOS doses of 76-151 mg and inulin doses of 114 mg were given to different groups treated with DMH. Results showed that ACF formation was significantly (p ≤ 0.05) less in high dose GalOS group (27.3%). GalOS also had protective effects against DMH-induced body weight loss and showed higher level of cecal and fecal SCFA (acetate, propionate and butyrate). High doses of GalOS also resulted in significant (p ≤ 0.05) reduction of bacterial enzymatic activities. Increased populations of beneficial bacteria (bifidobacteria and lactobacilli) and decreased concentrations of harmful bacteria were observed in all prebiotics treatment groups. It can be concluded that novel GalOS exhibit robust protective activity against ACF formation in vivo.

RESUMO

New strategies are required to improve the efficacy of drugs and to treat the emerging microbial resistance. An effective strategy is to combine drugs with metal nanoparticles for the control of microbial infections and resistance. Keeping in view this fact, we developed a facile and eco-friendly protocol for the synthesis of amphotericin B-conjugated silver nanoparticles and their assessment as an antifungal agent. Phytochemicals from the aqueous extract of Maytenus royleanus and amphotericin B were used as capping agents to prepare two types of silver nanoparticles i.e. (i) biogenic silver nanoparticles (b-AgNPs) and (ii) amphotericin B-conjugated biogenic silver nanoparticles (Amp-bAgNPs). UV-Vis spectroscopy was used to detect the characteristic surface Plasmon resonance peaks (SPR) for the prepared nanoparticles (424-433 nm). High-resolution transmission electron microscopy (HRTEM) study revealed the formation of well dispersed and spherical silver nanoparticles and Amp-bAgNPs with an average particles size of 10 and 15 nm. EDX and FTIR studies confirmed the elemental composition and surface adhered biomolecules in the prepared nanoparticles respectively. Biogenic silver nanoparticles revealed low to moderate antifungal activity (4-8 mm ± 0.2), however, the amphotericin B conjugated silver nanoparticles exhibited significant activity against Candida albicans (16 mm ± 1.4) and Candida tropicalis (18 mm ± 1.5). In conclusion, the enhanced antifungal activity of the Amp-AgNPs conjugate system is due to the synergy between the antifungal activity of amphotericin B and the antimicrobial property of silver. The findings of this study suggest that the conjugated nanoparticles could be used as efficient antifungal agents and drug delivery vehicles. Furthermore, this is the first report describing the synthesis of silver nanoparticles using the aqueous extract of Maytenus royleanus and the conjugation of amphotericin B, an antifungal drug, to the phytosynthesized silver nanoparticles.

RESUMO

OBJECTIVE: To identify the best assessment method for medical students with different learning approaches. METHODS: The cross-sectional questionnaire-based study was conducted at Bahria University Medical and Dental College, Karachi, from March 2010 to April 2011, and comprised first year medical students. The questionnaire was tailored from the Approaches and Study Skills Inventory for Students on a five-point scale Deep approach, Surface apathetic approach and Strategic approach were assessed through relevant sub-scales. Response to questions was summed for the subscales and main scales for a learning approach. Mean scores for aggregate marks obtained by multiple choice questions, short answer questions, problem-based learning and objective structured physical examination were derived. Coefficient of variation was estimated to find the most reliable assessment method. RESULTS: Of the 100 students enrolled, 98(98%) completed the study. Of them, 51(52%) were girls and 47(48%) were boys. Overall, 70(71.4%) students displayed Strategic approach, and 13(13.3%) showed Surface apathetic approach. Objective structured physical examination had the least variation (12.27) for all approaches whereas maximum variation (14.92) was observed by problem-based learning scores. CONCLUSIONS: Assessment by problem-based learning scores was able to demarcate deep learners whereas consistent scores were obtained by objective structured physical examination which failed to discriminate variance in performance by different learners.

RESUMO

OBJECTIVES: While state-based models of health-related quality of life (HRQL) are well-established in providing clinically relevant descriptions of HRQL status, they do not provide information on how to maintain or improve HRQL. The EvalUation of goal-diRected activities to prOmote well-beIng and heAlth (EUROIA), rooted in a novel process-based model of HRQL, measures goal-directed activities that are self-reported to promote HRQL as part of an individual's process of adapting to dynamic changes in health status. Our objectives were to condense and summarize the psychometric properties of the EUROIA by (i) defining and confirming its factor structure, (ii) evaluating its construct validity, and (iii) examining its internal consistency. METHODS: Principal component analysis was performed on the 18-item EUROIA to explore the underlying factor structure and condense the scale. Confirmatory factor analysis was conducted on the revised 14-item, 4-factor structure EUROIA instrument to evaluate the model fit. Data was obtained from adult participants with a diagnosis of chronic heart failure or advanced chronic kidney disease from 3 hospitals in Toronto, Canada. RESULTS: The revised 14-item EUROIA demonstrated 4 dimensions-Social Affiliation, fulfillment of Social Roles and Responsibilities, Self-Affirmation, and Eudaimonic Well-being-with a Cronbach's alpha of 0.83, representing good internal consistency. Our confirmatory factor analysis final model achieved good overall model fit: (χ2 / df = 1.80; Tucker-Lewis index = 0.90; comparative fit index = 0.93; standardized root-mean-square residual = 0.06; root-mean-square error of approximation = 0.06). All items exhibited a factor loading greater than λ > 0.4 and p < 0.001. CONCLUSION: The EUROIA holds clinical potential in its ability to provide informed feedback to patients on how they might maintain or modify their use of goal-directed activities to maintain and optimize perceived well-being.

RESUMO

BACKGROUND: The EvalUation of goal-diRected activities to prOmote well-beIng and heAlth (EUROIA) scale is a novel patient-reported measure that was administered to individuals with chronic heart failure (CHF). It assesses goal-directed activities that are self-reported as being personally meaningful and commonly utilized to optimize health-related quality of life (HRQL). Our aim was to evaluate psychometric properties of the EUROIA, and to determine if it accounted for novel variance in its association with clinical outcomes. METHODS: This study was a secondary analysis of the CHF-CePPORT trial, which enrolled 231 CHF patients: median age = 59.5 years, 23% women. Baseline assessments included: EUROIA, Kansas City Cardiomyopathy Questionnaire-Overall Summary (KCCQ-OS), Patient Health Questionnaire-9 for depression (PHQ-9), and the Generalized Anxiety Disorder-7 (GAD-7). 12-month outcomes included health status (composite index of incident hospitalization or emergency department, ED, visit) and mental health (PHQ-9 and GAD-7). RESULTS: Exploratory Principal Axis Factoring identified four EUROIA factors with satisfactory internal reliability: i.e., activities promoting eudaimonic well-being (McDondald's ω = 0.79), social affiliation (⍺=0.69), self-affirmation (⍺=0.73), and fulfillment of social roles/responsibilities (Spearman-Brown coefficient = 0.66). Multivariable logistic regression indicated that not only was the EUROIA inversely associated with incidence of 12-month hospitalization/ED visits independent of the KCCQ-OS (Odds Ratio, OR = 0.95, 95% Confidence Interval, CI, 0.91, 0.98), but it was also associated with 12-month PHQ-9 (OR = 0.91, 95% CI, 0.86, 0.97), and GAD-7 (OR = 0.94, 95% CI, 0.90, 0.99) whereas the KCCQ-OS was not. CONCLUSION: The EUROIA provides a preliminary taxonomy of goal-directed activities that promote HRQL among CHF patients independently from a current gold standard state-based measure.

RESUMO

INTRODUCTION: EBV has been a leading candidate as a trigger for several autoimmune diseases. We describe an antineutrophil cytoplasmic autoantibody (ANCA) -associated systemic vasculitis as the initial presenting illness of AIDS. CASE REPORT AND RESULTS: The patient was diagnosed ANCA -associated systemic vasculitis in the setting of HIV infection because of a high level of ANCA level, crescent glomerulonephritis in pathology, and clinical signs and symptoms compatible with systemic vasculitis. He also had HIV associated lymphadenopathy with scattered. EBV-RNA positive cells and reactive germinal centers. CONCLUSION: EBV genome was found in reactive lymph nodes and, therefore, may be associated with the immunopathogenesis of vasculitis.

RESUMO

BACKGROUND: Deficiency of silent information regulator 1 (SIRT1) can trigger inflammation, mitochondrial malfunctioning, and apoptosis through the hypothalamic-pituitary-ovarian axis, producing poor quality oocytes, leading to infertility. Normal vitamin D (VD) levels promote SIRT1 activity required for optimal fertility, and low levels of either may result in fertility problems owing to cell-membrane de-stabilization, increased autophagy, DNA damage leading to increased reactive oxygen species and mitochondrial dysfunction. Therefore, in this study, we want to estimate the levels of VD, SIRT1 and antioxidants (MnSOD; manganese superoxide dismutase, GR; glutathione reductase, visfatin) and oxidants (adrenaline & cortisol) in individuals living with infertility and explore the association of VD with SIRT1 expression (levels), antioxidants, and oxidants contributing to infertility in women. The significance of this study is that it highlights the importance of maintaining optimal levels of VD for reproductive health in females. METHODS: This cross-sectional study included 342 (135 infertile and 207 fertile) female subjects. Serum levels of MnSOD, SIRT1, visfatin, GR, VD, adrenaline, and cortisol were analyzed by ELISA and were compared in fertile and infertile samples using the Mann Whitney U test. RESULTS: There were significantly high levels of VD, SIRT1, GR, MnSOD and visfatin in fertile female participants. However, mean adrenaline and cortisol levels were higher in infertile samples with a significant negative correlation with VD. A significant negative correlation of VD with MnSOD, SIRT1, visfatin and GR was observed (p <0.01). In VD subset groups, MnSOD levels were significantly high in VD sufficient groups however, adrenaline and cortisol levels were significantly high in groups suffering from VD deficiency. CONCLUSIONS: Deficiency of VD is associated with a decrease in SIRT1 and other antioxidants, which may deter natural reproductive functions leading to infertility. Further studies are required to determine the cause-effect relationship of VD deficiency on conception and interpretation of the involved mechanism.

RESUMO

INTRODUCTION: Heart failure (HF) symptoms improve through self-care, for which adherence remains low among patients despite the provision of education for these behaviours by clinical teams. Open Access Digital Community Promoting Self-Care, Peer Support and Health Literacy (ODYSSEE-vCHAT) combines automated digital counselling with social network support to improve mortality and morbidity, engagement with self-care materials, and health-related quality of life. METHODS AND ANALYSIS: Use of ODYSSEE-vCHAT via Internet-connected personal computer by 162 HF patients will be compared with a control condition over 22 months. The primary outcome is a composite index score of all-cause mortality, all-cause emergency department visits, and HF-related hospitalisation at trial completion. Secondary outcomes include individual components of the composite index, engagement with self-care materials, and patient-reported measures of physical and psychosocial well-being, disease management, health literacy, and substance use. Patients are recruited from tertiary care hospitals in Toronto, Canada and randomised on a 1:1 ratio to both arms of the trial. Online assessments occur at baseline (t=0), months 4, 8 and 12, and trial completion. Ordinal logistic regression analyses and generalised linear models will evaluate primary and secondary outcomes. ETHICS AND DISSEMINATION: The trial has been approved by the research ethics boards at the University Health Network (20-5960), Sunnybrook Hospital (5117), and Mount Sinai Hospital (21-022-E). Informed consent of eligible patients occurs in person or online. Findings will be shared with key stakeholders and the public. Results will allow for the preparation of a Canada-wide phase III trial to evaluate the efficacy of ODYSSEE-vCHAT in improving clinical outcomes and raising the standard of outpatient care. TRIAL REGISTRATION NUMBER: NCT04966104.

RESUMO

OBJECTIVES: This research aimed at investigating the general public perception of social media (SM), impact of COVID-19 (SARS-CoV-2) pandemic, and related misconceptions among the Pakistani population. METHODOLOGY: Cross-sectional study conducted during the peak of COVID-19 in Pakistan between May and June, 2020 comprised of 2307 Pakistani male and female participants. Subjects under 18 years of age and nationality other than Pakistani were excluded. An online questionnaire was administered via the Internet using various kinds of social media. RESULTS: The study was comprised of 2307 male and female participants; 2074 (89.90%) used SM for seeking COVID-19 information, 450 (20%) used both Facebook (FB) and WhatsApp (WA), and 267 (11.6%) used FB, WA, Twitter, and Instagram. Respondents' perceptions showed that: 529 (23%) believed in SM information and 1564 (67.8%) stated that COVID-19 affected their social and mental wellbeing. Respondents' knowledge revealed that: 1509 (65.40%) had poor knowledge (≤ 50% score), and 798 (34.6%) had good knowledge (> 50% score) (P < 0.001) about COVID-19. Binary logistic regression analysis showed that higher-earning positively correlated, while private jobs were negatively associated, with good knowledge. CONCLUSION: FB and WA were the 2 common social media used by study participants (a third had good knowledge). COVID-19 affected the social, mental, and psychological well-being of individuals. Good knowledge was greater in individuals with higher earning and less with private job involvements.

RESUMO

Leishmaniasis, a category 1 disease, has remained neglected for decades, and therefore, has developed into a severe health problem worldwide. Unfortunately, the available antileishmanial drugs are limited, and the parasites have shown an inevitable resistance toward most of these drugs. All these factors pose a barrier to control the parasite at present. Hence, new strategies are needed to develop more effective and less toxic nanomedicines that could treat and manage the Leishmania parasite. One of these effective strategies is to construct nanometals with biologically active molecules that could possess dynamic antileishmanial activities with desirable biocompatibility. In this review paper, antileishmanial potencies of different metal nanoparticles, with particular emphasis on biogenic metal nanoparticles from 2011 to 2019, are summarized. The mechanisms by which metal-based nanomedicines kill Leishmania are also discussed.

RESUMO

To minimize the hazardous effect of physical and chemical synthesis of nanoparticles we focused on the green synthesis of nanoparticles. Nanotechnology is a research hotspot and catch great attention because of its versatile applications in medical, biosciences and engineering fields. Purpose of our recent study is to synthesize bio-inspired metallic silver NPs by root mediated Zingiber officianale extract. The synthesized Ag-NPs were further characterized by using UVVisible spectroscopy, XRD, EDX, SEM, TEM and DLS techniques. The extent of crystallites were confirmed by X-ray diffraction. SEM and TEM revealed the morphological features with size of nanoparticles between 17.3 and 41.2 nm. FTIR analysis confirmed the capping of nanoparticles by bio active constituents present in Zingiber officinale extract. Later EDX confirmed the elemental composition of nanoparticles. Zeta potential, PDI and hydrodynamic size of Ag-NPs were confirmed by DLS. The synthesize Ag-NPs possess eminent biological potency against bacterial and leishmanial strains. Moreover considerable anti-diabetic, anticancer, antioxidant and biocompatibility nature of Ag-NPs was elucidated. The highest antioxidant activity of 50.61± 1.12%, 38.22 ± 1.18% and 27.39 ± 0.92 at 200 g/mL for TAC, TRP DPPH and was observed respectively. Ag-NPs exhibit potent leishmanicidal activity of 80% ± 1.4 against promastigotes and 77% ± 1.6 against amastigotes cultures of L. tropica. Highest antidiabetic activity 30 ± 0.77% recorded at 200 µg/ml. Highest Brine shrimps cytotoxicity of Ag-NPs was 60 ± 1.18 at 200 g/ml. Maximum dye degradation for Ag-NPs was recorded as 94.1% at 140 minute. All UTI isolates were resistant to antibiotics not coated with Ag-NPs. By applying 1% of Ag-NPs highest activity was recorded as 25 ± 1.58 mm against K. pneumoniae. Maximum zone of inhibition for Ag-NPs coated with Imipenem antibiotics 26 ± 1.5 mm against K. pneumoniae and coated with Ciprofloxacin 26 ± 1.4 m against S. aureus were measured. Last but not least high biocompatible nature of Ag-NPs was observed against fresh RBCs making the ecofriendly biosynthesized silver NPs a multi-dimensional candidate in biomedical field.

RESUMO

STUDY OBJECTIVE: Adnexal torsion (AT) requires urgent surgical intervention to preserve ovarian function. Historically, treatment for AT was oophorectomy because of concerns related to leaving a nonviable ischemic ovary. No published studies support these theoretical concerns and current literature supports conservative management. The aim of this study was to review the institutional outcomes for AT cases, including salvage rates and complications. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: This study was approved by the institutional review board at Baylor College of Medicine. A retrospective chart review on cases of AT from 2007 to 2016 at a single Children's hospital was performed on the basis of International Classification of Diseases, 10th revision and Current Procedural Terminology codes. A standardized chart review form was used in data extraction. Statistical analysis was performed using SAS version 9.4 (SAS Institute). RESULTS: Chart review identified 245 torsion cases in 237 patients. The mean age was 12.4 ± 3.29 years. Of the participants, 230 (94%) underwent minimally invasive laparoscopy with ovarian preservation in 233 (95%) of the cases. There were no complications due to detorsion of the affected adnexa. Intraoperatively, the right adnexa was affected in 134 (55%) cases and a lesion was noted in 193 (79%) cases, most commonly paratubal cysts and mature teratomas. The malignancy rate was low, noted only in 4/245 patients at (1.2%). Pediatric gynecology performed most of the cases (n = 214; 87%). CONCLUSION: The findings of our study continue to support the conservative management of patients with AT.
