RESUMO
Menstrual disturbances are common among adolescents with a prevalence rate of 11.3-26.7%. The most frequent menstrual irregularities are oligomenorrhea, menorrhagia, polymenorrhoea, and hypomenorrhea. PCOS (polycystic ovarian syndrome) is now recognized as the most prevalent endocrine disorder among the women of reproductive age. The current study was planned to evaluate socio-demographic factors, endocrine profiles, and ovarian morphology among adolescent girls with menstrual irregularities and compare these parameters in different phenotypes of adolescent PCOS cases. It is a hospital-based cross-sectional study among 248 adolescent girls (10-19 years) with menstrual irregularities. After obtaining informed consent, history and clinical examination findings were recorded on preform proforma. All girls were assessed on day 2/3 of the menstrual cycle for hormonal profile (serum TSH, FSH, LH, prolactin, and serum testosterone) and ovarian morphology (by transabdominal ultrasonography). All participating girls were divided into three groups (groups 1, 2, and 3) corresponding to phenotypes A, B, & D as per the Rotterdam criteria. In the study, oligomenorrhea was the most common menstrual disorder (70.97%). Biochemical hyperandrogenism and thyroid dysfunction were reported in 14.91% and 8.46% of girls, respectively. Our study noted that phenotype D ,i.e., group 3 (MI + PCOM-HA; 49.43%) was the most common phenotype in the study. In a comparative analysis of different groups, significant differences (p < 0.05) in hormonal and metabolic parameters showed highest in group 2, which represents phenotype B of PCOS (hyperandrogenic anovulation). This analysis revealed that adolescent hyperandrogenism (phenotypes A and B) is associated with a more deranged hormonal and metabolic profile than nonandrogenic PCOS (phenotype D). To prevent long-term sequelae, lifestyle changes, early treatment, and close follow-up are recommended in this subset of girls.

Keratin 8/18, the predominant keratin pair of simple epithelia, is known to be aberrantly expressed in several squamous cell carcinomas (SCCs), where its expression is often correlated with increased invasion, neoplastic progression, and poor prognosis. The majority of keratin 8/18 structural and regulatory functions are governed by posttranslational modifications, particularly phosphorylation. Apart from filament reorganization, cellular processes including cell cycle, cell growth, cellular stress, and apoptosis are known to be orchestrated by K8 phosphorylation at specific residues in the head and tail domains. Even though deregulation of K8 phosphorylation at two significant sites (Serine73 /Serine431 ) has been implicated in neoplastic progression of SCCs by various in vitro studies, including ours, it is reported to be highly context-dependent. Therefore, to delineate the precise role of Kereatin 8 phosphorylation in cancer initiation and progression, we have developed the tissue-specific transgenic mouse model expressing Keratin 8 wild type and phosphodead mutants under Keratin 14 promoter. Subjecting these mice to 7,12-dimethylbenz(a)anthracene/12-O-tetradecanoylphorbol-13-acetate-mediated skin carcinogenesis revealed that Keratin 8 phosphorylation may lead to an early onset of tumors compared to Keratin 8 wild-type expressing mice. Conclusively, the transgenic mouse model developed in the present study ascertained a positive impact of Keratin 8 phosphorylation on the neoplastic transformation of skin-squamous cells.

OBJECTIVES: Given the disparity that exists in enrollment of minorities to oncology clinical trials, the objective of our study was to assess whether race is associated with willingness to participate in gynecologic oncology clinical trials in a rural Southern academic medicine setting. Our secondary aim was to determine whether willingness to participate is impacted by an educational intervention. METHODS: A single institution prospective survey study was performed at an academic medical center. Women presenting to the gynecologic oncology clinic with a current or prior diagnosis of gynecologic malignancy were approached to participate. The validated Attitudes to Randomized Trials Questionnaire (ARTQ) assessed willingness to participate in clinical trials. Relevant demographic and clinical data were abstracted. Characteristics were compared between those willing and unwilling to participate in clinical trials with a chi-square test for categorical variables and Wilcoxon rank sum tests for continuous data. RESULTS: We enrolled 156 participants (50% White, 50% non-White) from May 2017 to January 2018. The minority group included 35% non-Hispanic Black, 9% Hispanic, 4% Asian, and 2% other. Median age was 63 years with endometrial cancer being the most common diagnosis (48%). On initial screen, only 35% were willing to participate in a clinical trial. Willingness to participate did not differ between race, age, marital status, education level, cancer type, stage, or mode of treatment. Rates improved to 82% after being provided additional educational information. Following education, White women and those with more education were significantly more willing to participate in clinical trials than their minority and less educated counterparts. CONCLUSIONS: Willingness to participate improved among all sub-categories following an educational intervention. The increase in willingness was less robust among racial and ethnic minorities, suggesting that different tools are needed for recruitment of minorities to gynecologic oncology clinical trials.

Magnetic iron oxide nanoparticles (IONs) display the ability to cross blood - brain barrier and are envisioned as diagnostic and therapeutic applications, but there are few studies on their potential embryonic toxicity in higher vertebrates. This study investigates interaction of IONs with egg albumen and its subsequent toxicity on chicken embryo. Physicochemical interactions of IONs with egg albumen revealed alterations in friccohesity and secondary structural changes due to weak Vander Waals forces. Toxicity assessment of IONs (10, 25, 50, 100, and 200 µg/ml doses) on chicken embryo accounted for 100% mortality at 200 µg/ml dose due to Fe2+ ions overload. However, lower doses (50 and 100 µg/ml) recorded decrement in whole weights and crown-rump lengths of chicken embryo possibly due to ION-albumen interactions. Histology of brain tissue revealed degeneration of neurons (50-60%) at 10-100 µg/ml dose range of IONs. Toxicity studies of IONs with diverse animal models are needed to set a toxicity benchmark for preventing embryonic toxicity prior to its use in biomedical applications. This is the first study on toxicity assessment of IONs in chicken embryo.

Hypertonic NaCl is first-line therapy for acute, severe and symptomatic hyponatremia; however, its use is often restricted to the intensive care unit (ICU). A 35-year-old female inpatient with an optic chiasm glioma and ventriculoperitoneal shunt for hydrocephalus developed acute hyponatremia (sodium 122 mEq/l) perhaps coinciding with haloperidol treatment. The sum of her urinary sodium and potassium concentrations was markedly hypertonic vis-à-vis plasma; it was inferred that serum sodium concentration would continue to fall even in the complete absence of fluid intake. Intravenous (i.v.) 3% NaCl was recommended; however, a city-wide public health emergency precluded her transfer to the ICU. She was treated with hourly oral NaCl tablets in a dose calculated to deliver the equivalent of 0.5 ml/kg/h of 3% NaCl with an objective of increasing the serum sodium concentration by 6 mEq/l. She experienced a graded and predictable increase in serum sodium concentration. A slight overshoot to 129 mEq/l was rapidly corrected with 0.25 l of D5W, and she stabilized at 127 mEq/l. We conclude that hourly oral NaCl, in conjunction with careful monitoring of the serum sodium concentration, may provide an attractive alternative to i.v. 3% NaCl for selected patients with severe hyponatremia.

AIM: To assess patients' and healthcare professionals' perspectives of a specialist-led Diabetes Risk-based Assessment Clinic (DIRAC) for people with diabetes at high risk of complications (PWDHRC) in areas of deprivation in Coventry, UK. METHODS: A qualitative evaluation of a pilot trial, comprising a specialist team intervention (DIRAC), was undertaken in seven GP practices through observations of weekly virtual or occasional face-to-face patient consultations and monthly interventionists' meetings. Semi-structured interviews were carried out post-intervention, with PWDHRC, primary care clinicians and diabetes specialists (interventionists). Thematic analyses of observations and interviews were undertaken. KEY FINDINGS: Over 12 months, 28 DIRAC clinics comprising 154 patient consultations and five interventionists' meetings, were observed. 19 interviews were undertaken, PWDHRC experienced 'culturally-sensitive care from a specialist-led clinic intervention encompassing integrated care. This model of care was recommended at GP practice level, all participants (PWDHRC, primary care clinicians and diabetes specialist interventionists) felt upskilled to deal with complex diabetes care. The EMIS and ECLIPSE technologies utilised during the intervention were perceived to positively contribute to diabetes management of PWDHRC despite reservations around cost and database. CONCLUSION: The specialist-led DIRACs were largely appreciated by study participants. These qualitative data support the trial progressing to a full-service evaluation.

Surface proteins on the membrane of nano-sized extracellular vesicles (EVs) not only play crucial roles in cell-to-cell communication, but also are specific binding targets for EV detection, isolation and tracking. The low abundance of protein biomarkers on EV surface, the formation of clusters and the complex EV surface network impose significant challenges to the study of EVs. Employing bulky sized affinity ligands, such as antibodies, in the detection and characterization of these vesicles often result in reduced sensitivity of detection or poor quantification of proteins on the EV surface. By virtue of their small size and high specificity, Affibody molecules emerge as a potential alternative to their monoclonal antibody counterparts as robust affinity ligands in EV research. In this study, we present a theoretical framework on the superiority of anti-HER2 Affibodies over anti-HER2 antibodies in labeling and detecting HER2-positive EVs, followed by the demonstration of the advantages of HER2 Affibodies in accessing EV surface and the detection of EVs through multiple types of approaches including fluorescence intensity, colorimetry, and fluorescence polarization. HER2 Affibodies outperformed by 10-fold over three HER2 antibody clones in accessing HER2-positive EVs derived from different human cancer cell lines. Furthermore, HRP-Affibody molecules could detect EVs from cancer cells spiked into human serum with at least a 2-fold higher sensitivity compared with that of their antibody counterparts. In addition, in fluorescence polarization assays in which no separation of free from bound ligand is required, FITC-labeled HER2 Affibodies could sensitively detect HER2-positive EVs with a clinically relevant limit of detection, whilst HER2 antibodies failed to detect EVs in the same conditions. With the demonstrated superiority in accessing and detecting surface targets over bulky-sized antibodies in EVs, Affibodies may become the next-generation of affinity ligands in the precise characterization and quantification of molecular architecture on the surface of EVs.

BACKGROUND: Estrogen receptor-α (ERα)-negative breast cancer is clinically aggressive and normally does not respond to conventional estrogen target-directed therapies. The soybean isoflavone, genistein (GE), has been shown to prevent and inhibit breast cancer and recent studies have suggested that GE can enhance the anticancer capacity of an estrogen antagonist, tamoxifen (TAM), especially in ERα-positive breast cancer cells. However, the role of GE in ERα-negative breast cancer remains unknown. METHODS: We have evaluated the in vitro and in vivo epigenetic effects of GE on ERα reactivation by using MTT assay, real-time reverse transcription-polymerase chain reaction (RT-PCR) assay, western-blot assay, immunoprecipitation (ChIP) assay, immunohistochemistry and epigenetic enzymatic activity analysis. Preclinical mouse models including xenograft and spontaneous breast cancer mouse models were used to test the efficacy of GE in vivo. RESULTS: We found that GE can reactivate ERα expression and this effect was synergistically enhanced when combined with a histone deacetylase (HDAC) inhibitor, trichostatin A (TSA), in ERα-negative MDA-MB-231 breast cancer cells. GE treatment also re-sensitized ERα-dependent cellular responses to activator 17ß-estradiol (E2) and antagonist TAM. Further studies revealed that GE can lead to remodeling of the chromatin structure in the ERα promoter thereby contributing to ERα reactivation. Consistently, dietary GE significantly prevented cancer development and reduced the growth of ERα-negative mouse breast tumors. Dietary GE further enhanced TAM-induced anti-cancer efficacy due at least in part to epigenetic ERα reactivation. CONCLUSIONS: Our studies suggest that soybean genistein can epigenetically restore ERα expression, which in turn increases TAM-dependent anti-estrogen therapeutic sensitivity in vitro and in vivo. The results from our studies reveal a novel therapeutic combination approach using bioactive soybean product and anti-hormone therapy in refractory ERα-negative breast cancer which will provide more effective options in breast cancer therapy.

Background Urinary albumin creatinine ratio (ACR) is a known method of measurement of microalbuminuria. Microalbuminuria may be an early marker of endothelial dysfunction which can lead to various complications during the course of pregnancy. The objective of our study was to evaluate the correlation of mid-trimester spot urinary ACR with the pregnancy outcome. Material and methods We performed a prospective cohort study in the department of Obstetrics & Gynaecology, All India Institute of Medical Sciences, Bhopal, for a period of one year. We studied 130 antenatal women between 14 and 28 weeks of gestation after obtaining written informed consent. The patients with ongoing urinary tract infection (UTI), pre-existing hypertension, or diabetes were excluded. Urinary samples were examined for spot ACR, and the women were followed until delivery. Primary maternal outcomes were development of gestational hypertension, pre-eclampsia, gestational diabetes mellitus (GDM), and preterm labour. Neonatal outcome was assessed in terms of birth weight, the APGAR (Appearance, Pulse, Grimace, Activity, Respiration) scores, and neonatal intensive care unit (NICU) admission. Results In our study, mean urinary ACR was 19.07±12.94 mcg/mg and median urinary ACR (IQR) was 18 (9.43-25.25) mcg/mg. Prevalence of microalbuminuria in our study was 19.2%. It was observed that urinary ACR level was significantly higher in women with maternal complications like GDM, gestational hypertension, preeclampsia, and preterm labour. Also, mean urinary ACR of women who developed preeclampsia was higher (37.53±31.85) compared to women who developed gestational hypertension (27.40±9.71). Urinary ACR level was significantly higher in babies with low APGAR scores and in babies who needed NICU admission (p value < 0.05). The sensitivity and specificity of spot urinary ACR to predict GDM and preeclampsia were found to be good as calculated from the receiver operating curve. Conclusion We found definite correlation of higher values of mid-trimester urinary ACR with the adverse pregnancy outcome.
RESUMO
Ovarian stroma and surface epithelium develop from two different embryological primordia and give rise to tumors of distinct characteristics. The simultaneous presence of two kinds of ovarian tumors in one patient is rare. Concurrent presence of a large ovarian fibroma in one ovary, and a serous cystadenoma in the seemingly normal-looking contralateral ovary was found in a 55-year-old woman. The unusual coexistence of these tumors warrants a closer and longer follow-up of the patient. To the best of our knowledge, this is the fourth case to be reported in the literature. All surgically isolated tissues should undergo detailed histopathological examination, including normal-looking tissues which are excised as a part of the procedure.
RESUMO
This study was conducted to identify and study the prevalence of post traumatic stress disorder (PTSD) in patients, who had sustained traumatic facial and dental injuries along with other variables that may affect the psychological response. MATERIAL AND METHODS: 241 patients suffering from traumatic facial and dental injuries presenting to the Ahmadabad Municipal Dental College and Hospital were included in the study. 110 patients (males - 87, females - 23) suffered disfiguring injuries and/or loss of multiple front teeth (DF). 131 patients (males - 102, females - 29) suffered no disfigurement (NDF). Assessment was carried out on day of discharge (D.O.D), 1 month, and 6 months. Impact of Event Scale (I.E.S-R) was used to assess the presence of post traumatic stress disorder in the patients. RESULTS: Patients with DF injuries had statistically significant higher mean scores than patients suffering NDF injuries. Female patients had comparatively higher scores at D.O.D, 1 month, and 6 months. Patients treated with maxillomandibular fixation and between ages 18 and 40 years also had significantly higher scores. CONCLUSION: Patients with DF facial injuries including multiple anterior teeth loss had significantly higher mean (I.E.S-R) scores for PTSD in comparison with patients with NDF facial injuries.

Introduction Polycystic ovary syndrome (PCOS) is a frequently occurring endocrine condition prevalent in women of reproductive age characterized by chronic anovulation, hyperandrogenism, insulin resistance, and a low-grade inflammatory state. Patients with PCOS are more vulnerable to developing cardiac and metabolic co-morbidities. Sympathetic overactivity is also reported in PCOS patients. Objective This study aimed to assess cardiac autonomic function in PCOS by Heart Rate Variability Analysis, Ewing's Test, and Composite Autonomic Symptom Scale-31 (COMPASS-31). Methods Thirty female PCOS patients and 30 age-matched control females were enrolled in the study. Both cases and controls were subdivided into sub-groups based on body mass index (BMI) and waist-to-hip ratio (WHR). The cardiac autonomic functions were assessed by the COMPASS-31 questionnaire, Ewing's battery tests, and short-term heart rate variability analysis. Results There was no significant difference in age, BMI, and WHR of both groups. Additionally, cases had a significantly higher low frequency to high frequency (LF/HF) ratio and COMPASS-31 score and also reported more derangement in Ewing's battery test, indicating cardiac autonomic dysfunction in PCOS patients. Conclusion Patients with PCOS are more prone to developing cardiac and metabolic co-morbidities. Early assessment of cardiac autonomic function can prevent future complications with timely interventions. Altered autonomic function in PCOS patients can be due to hyperandrogenism and insulin resistance.
RESUMO
Objective: To analyze the safety and efficacy of repetitive transcranial magnetic stimulation (rTMS) for major depressive disorder, schizophrenia, and obsessive-compulsive disorder (OCD) via umbrella meta-analysis.Data Sources: Meta-analysis studies were searched in PubMed from inception to May 2021 using the keywords anxiety, depression, ADHD, schizophrenia, mood disorder, OCD, psychiatric disorders, GAD, bipolar disorders, ASD, PTSD, transcranial magnetic stimulation, transcranial, magnetic, stimulation. PRISMA guidelines were followed.Study Selection: Abstracts and full-length articles were reviewed for meta-analysis studies with data on the safety and efficacy of rTMS and sham and were collected for quantitative analysis. The full texts of all identified studies were independently screened and assessed to determine eligibility. Any disagreement was resolved through consensus.Data Extraction: The descriptive variables extracted included the author names, study year, sample size, studies included in the meta-analysis, study period, and type of intervention.Results: 28 meta-analyses were included; 13 were on treatment-resistant depression, 9 on schizophrenia, and 6 on OCD. In treatment-resistant depression, the rTMS group had higher odds of response compared to sham (odds ratio [OR] = 3.27; 95% CI, 2.76-3.87; P < .00001) and higher odds of remission (secondary outcome) (OR = 2.83; 95% CI, 2.33-3.45; P < .00001). rTMS was superior to sham in the reduction of negative symptoms of schizophrenia (mean difference [MD]: 0.47; 95% CI, 0.23-0.7; P < .0001). However, no significant difference was found between the effects of rTMS and sham on auditory hallucinations (MD: 0.24; 95% CI, 0.26-0.74; P = .35), which resulted in 94% heterogeneity. TMS was better than sham in reducing the severity of OCD symptoms (MD: 0.81; 95% CI, 0.53-1.10; P < .00001).Conclusions: The effectiveness of rTMS for symptom reduction in various psychiatric disorders is associated with differences in neuropathology, disease-specific target site, and frequency of rTMS.Prim Care Companion CNS Disord 2023;25(5):22r03423.

Over the past decade, there has been a significant expansion in the development of plant-derived extracellular nanovesicles (EVs) as an effective drug delivery system for precision therapy. However, the lack of effective methods for the isolation and characterization of plant EVs hampers progress in the field. To solve a challenge related to systemic separation and characterization in the plant-derived EV field, herein, we report the development of a simple 3D inner filter-based method that allows the extraction of apoplastic fluid (AF) from blueberry, facilitating EV isolation as well as effective downstream applications. Class I chitinase (PR-3) was found in blueberry-derived EVs (BENVs). As Class I chitinase is expressed in a wide range of plants, it could serve as a universal marker for plant-derived EVs. Significantly, the BENVs exhibit not only higher drug loading capacity than that reported for other EVs but also possess the ability to modulate the release of the proinflammatory cytokine IL-8 and total glutathione in response to oxidative stress. Therefore, the BENV is a promising edible multifunctional nano-bio-platform for future immunomodulatory therapies.
RESUMO
AIM: The study was conducted to know the impact of COVID-19 vaccination on menstrual cycle patterns and pre- and post-menstrual symptoms in women aged 18-45 years. BACKGROUND: COVID-19 vaccination was introduced to combat the dreadful impacts of human coronavirus infection. The two indigenously developed COVID-19 vaccines approved for use in India are COVISHILED and COVAXIN. OBJECTIVES: To investigate the effects of COVID-19 vaccination on the menstrual cycle, pre- and post-menstrual symptoms and to establish the correlation with the type of vaccine received. METHODS: Multi-centric observational study conducted in six institutes of national importance in different states of India over one year. A total of 5709 female participants fulfilling inclusion criteria were enrolled. Data about the impact of vaccines (COVISHIELD and COVAXIN) and prior COVID-19 infection on the menstrual cycle and its associated symptoms were obtained using all participants' online and offline interviews. RESULTS: Of 5709 participants, 78.2% received COVISHIELD and 21.8% COVAXIN. Of the total 5709 participants, 333(5.8%) developed post-vaccination menstrual disturbances, with 32.7% having frequent cycles, 63.7% prolonged cycles, and 3.6% inter-menstrual bleeding. A total of 301 participants noticed changes in the amount of bleeding, with 50.2% excessive, 48.8% scanty, and 0.99% amenorrhea followed by heavy bleeding. Furthermore, the irregularities of the menstrual cycle (p=0.011) and length (0.001) were significantly higher in the COVAXIN group (7.2%) as compared to the COVISHIELD (5.3%) group. A total of 721 participants complained of newly developed/worsening pre- and post-menstrual symptoms. These symptoms were significantly higher in the COVISHIELD group (p=0.031), with generalized weakness and body pains as the main complaints (p=0.001). No significant difference was observed in the incidence of COVID-19 infection with these vaccines. No significant associations were observed when comparing menstrual abnormalities among those with COVID-19 infection (p>0.05). CONCLUSIONS: COVISHILED and COVAXIN vaccines were associated with menstrual cycle disturbances and pre-and post-menstrual symptoms in a small proportion of participants, with 94.7% having no change in the amount of bleeding during menstruation post-vaccination. The menstrual irregularities observed were significantly higher with the COVAXIN vaccine. Others: Further, long-term studies are required to confirm that the impact of COVID-19 vaccination on the menstrual cycle may be short-lasting, with no severe effects on women's menstrual health.
RESUMO
Genital outflow tract obstruction due to cervical agenesis is an uncommon Mullerian duct anomaly, increasingly being treated with conservative surgery by creation of an outflow tract by drilling or coring into the cervical remnant or by uterovaginal anastomosis. A 19-year-old woman with cervical dysgenesis in the present case underwent a successful uterovaginal anastomosis to relieve the obstructive menstrual symptoms and preserve the future reproductive function. The neouterovaginal canal was created over a mold of Foley's catheter by anastomosis anterior surface of the uterine corpus to the vaginal vault, bypassing the dysgenetic cervix and using the fibrous band of cervix as support. Normal cyclical menses were restored. Steps of the procedure are detailed in this case report.
RESUMO
The morbidly adherent placenta has evolved into one of the potentially life-threatening conditions in obstetrics. Vaginal bleeding is the most common presentation of placenta percreta. Other symptoms include unusual dull, prolonged lower abdominal pain. Although haematuria is rare, it may be a presentation of the morbidly adherent placenta in early pregnancy. We report a case of placenta percreta with a very uncommon presentation of gross haematuria early in the second trimester managed successfully. It is emphasized that a high index of suspicion, ultrasound, and/or MRI can establish a preoperative diagnosis of the invasive placenta earlier. However, the diagnostic accuracy of cystoscopy is still under debate. With timely diagnosis, preparedness, and multidisciplinary care, it is possible to minimize catastrophic complications.
RESUMO
Background Ultrasound examination has been a crucial part of the evaluation of fetal health during pregnancy. It has become more accurate over the past few decades as a result of advances in radiodiagnostic imaging. While obstetric ultrasonography in the first trimester has been utilized extensively for gestational age assessment and confirmation of fetal viability, the imaging technique has seen little exposure in predicting pregnancy outcomes. This study was thus undertaken to find out any possible association between one of the first trimester parameters, i.e. crown-rump length (CRL) noted at the beginning of a pregnancy, and the birth weight of the neonate. Methods This prospective cohort study conducted at a teaching hospital in India spanning over a period of eighteen months included women with a spontaneously conceived intrauterine pregnancy at six to ten weeks period of gestation as calculated from the last menstrual period. Transvaginal sonography was performed for all such women and the CRL was noted. These CRL values were then compared to a standard nomogram and assigned to either of three categories i.e. CRL <5th centile, 5th to 95th centile, or >95th centile. The women were then followed up at the hospital with standard care till the end of their pregnancy, and finally, the birth weights were noted. Data were recorded in an MS Excel spreadsheet program and analysis was performed with regard to CRL in the first trimester and birth weights using SPSS v23 (IBM Corp.). Results Crown-rump lengths and birth weights of 104 cases were evaluated. The mean age of the study population was 26.6 years and the mean period of gestation (weeks) was 8.28 ± 1.01. The incidence of low birth weight (LBW) in the study was 22.1%. The distribution of LBW was significantly different between the three CRL categories (χ2 = 15.868, p = <0.001), being considerably higher in the CRL <5th centile category. No embryos with CRL >95th centile had low birth weight. Conclusions Our study suggested a congruence between the crown-rump length of an embryo noted in the first trimester and its weight at birth, with low birth weight being a fairly common occurrence in the deficient CRL category. This study highlights the role of a carefully performed first-trimester ultrasound examination in possibly predicting an adverse pregnancy outcome such as low birth weight and the probable inherent tendency of growth restriction in fetuses that are destined to develop the same.
RESUMO
Uterine perforation following postplacental intrauterine contraceptive device (PPIUCD) insertion is a rare event with a potential for serious injuries. In the present case, a young lady with a history of PPIUCD insertion presented with a mass having ill-defined margins and restricted mobility palpable in her right iliac region. Examination reported a conglomerated mass in right adnexa with an IUCD surrounded by a heterogeneous inflammatory collection to which omentum and bowel loops adherent to it. Additional imaging reported involvement of right iliac vessels and right ureter with upstream hydroureteronephrosis. Intraoperatively, ureter was found intact and away from the IUCD which was removed with a gentle pull, and a rent in the right posterolateral surface of uterus was repaired with delayed absorbable sutures. With PPIUCD services being provided on an unprecedented scale, it becomes prudent and ethically crucial to create a national repository to document post insertion outcomes and complications. Case report aims to inform and sensitize stakeholders about possible post insertion complications to help improve expansion of the PPIUCD programs.
