Acute pelvic pain in females in septic and aseptic contexts

ACR Appropriateness Criteria® Sepsis

Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection. A search for the underlying cause of infection typically includes radiological imaging as part of this investigation. This document focuses on thoracic and abdominopelvic causes of sepsis. In 2017, the global incidence of sepsis was estimated to be 48.9 million cases, with 11 million sepsis-related deaths (accounting for nearly 20% of all global deaths); therefore, understanding which imaging modalities and types of studies are acceptable or not acceptable is imperative. The 5 variants provided include the most commonly encountered scenarios in the setting of sepsis along with recommendations and data for each imaging study. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Comparison of risk prediction models for the progression of pelvic inflammatory disease patients to sepsis: Cox regression model and machine learning model

Introduction

The present study presents the development and validation of a clinical prediction model using random survival forest (RSF) and stepwise Cox regression, aiming to predict the probability of pelvic inflammatory disease (PID) progressing to sepsis.

Methods

A retrospective cohort study was conducted, gathering clinical data of patients diagnosed with PID between 2008 and 2019 from the Medical Information Mart for Intensive Care (MIMIC)-IV database. Patients who met the Sepsis 3.0 diagnostic criteria were selected, with sepsis as the outcome. Univariate Cox regression and stepwise Cox regression were used to screen variables for constructing a nomogram. Moreover, an RSF model was created using machine learning algorithms. To verify the model's performance, a calibration curve, decision curve analysis (DCA), and receiver operating characteristic (ROC) curve were utilized. Furthermore, the capabilities of the two models for estimating the incidence of sepsis in PID patients within 3 and 7 days were compared.

Results

A total of 1064 PID patients were included, of whom 54 had progressed to sepsis. The established nomogram highlighted dialysis, reduced platelet (PLT) counts, history of pneumonia, medication of glucocorticoids, and increased leukocyte counts as significant predictive factors. The areas under the curve (AUCs) of the nomogram for prediction of PID progression to sepsis at 3-day and 7-day (3-/7-day) in the training set and the validation set were 0.886/0.863 and 0.824/0.726, respectively, and the C-index of the model was 0.8905. The RSF displayed excellent performance, with AUCs of 0.939/0.919 and 0.712/0.571 for 3-/7-day risk prediction in the training set and validation set, respectively.

Conclusion

The nomogram accurately predicted the incidence of sepsis in PID patients, and relevant risk factors were identified. While the RSF model outperformed the Cox regression models in predicting sepsis incidence, its performance exhibited some instability. On the other hand, the Cox regression-based nomogram displayed stable performance and improved interpretability, thereby supporting clinical decision-making in PID treatment.

[Epidemiological, clinical and therapeutic features of acute pelvic pain in female patients hospitalized in the Yaoundé Gynaecology-Obstetrics and Pediatrics Hospital]

Introduction

Les algies pelviennes aiguës sont responsables d’une morbi-mortalité importante. L’objectif de ce travail était de décrire leurs aspects épidémiologiques, cliniques et thérapeutiques à Yaoundé

Méthodes

Nous avons mené une étude transversale descriptive avec collecte prospective des données au Service de Gynécologie-Obstétrique de l’Hôpital Gynéco-Obstétrique et Pédiatrique de Yaoundé du 1^er avril au 31 juillet 2015. Nous avons inclus toutes les femmes admises pour douleur pelvienne dont l’évolution était inférieure à un mois et ayant accepté de participer à l’étude. Nous avons exclu les femmes qui étaient au troisième trimestre de grossesse ou en post-partum. Le logiciel Epi info version 3.5.4 a servi à l’analyse des données. Ces données ont été présentées sous forme de fréquence et de pourcentage.

Résultats

Au total 5915 femmes ont consulté pendant la période de l’étude dont 125(2,11%) étaient des algies pelviennes aiguës. La moyenne d’âge était de 29,5 ± 6,9 ans. Les étiologies des douleurs étaient les infections génitales hautes (36,8%) et la grossesse extra-utérine (18,4%). Le traitement surtout médical (92,8%), associait antibiotiques (65,5%), anti-inflammatoires (56,9%) et antalgiques (39,7%). La chirurgie a été réalisée chez 25(20%) patientes par laparotomie (80%) et cœlioscopie (20%). L’indication chirurgicale était la grossesse extra-utérine dans 76% des cas. La régression de la douleur était obtenue chez 99% des cas.

Conclusion

Les d’algies pelviennes aigues survenaient chez les femmes jeunes, dues aux infections génitales hautes et à la grossesse extra-utérine étaient principalement. En cas de grossesse extra-utérine le traitement chirurgical était surtout la laparotomie.

The effect of controlled reperfusion on experimental ovarian torsion

The objective of our research was to study the effect of controlled reperfusion on lactate and advanced oxidation protein products (AOPP) in experimental ovarian torsion (OT), and to evaluate the possibility to reduce the reperfusion injuries applying the ON-OFF technique of reperfusion. Material and Methods — Lactate and AOPP were measured in serum and ovarian homogenates of 70 females rats, divided equally into 7 groups: no intervention (nr. 1); laparotomy (nr. 2); 3 hours OT (nr. 3); 3 hours OT + 1 hour (nr. 4) or 24 hours (nr. 6) of simple reperfusion (SR); 3 hours OT + 1 hour (nr. 5) or 24 hours (nr. 7) of controlled reperfusion (ON-OFF). The results were analyzed using Welch's ANOVA. Results — OT produced an increase of serum (66%, p<0.001) and homogenate (38%, p=0.006) lactate, that tended to return to baseline in 24 hours despite the type of reperfusion. AOPP had grown in OT animals serum (20%, p=0.007) and homogenate (26%, p>0.05) and continued to rise in the serum after SR, while in ON-OFF technique groups – decreased by about 20% (p<0.01). Homogenate AOPP levels rised after reperfusion in all groups. Conclusion — Lactate is a biomarker for ischemia in OT. Increased AOPP in experimental groups indicates that there is a degree of oxidative stress that can affect the cells after the restoration of the blood flow. Therefore, the correct management of the condition that reduces reactive oxygen species production, such as controlled method of reperfusion, could be appropriate to prevent additional injuries.

[Acute Pelvic pain in women-gynecological causes]

BACKGROUND

Acute pelvic pain in women may be due to gynecological, gastrointestinal, and urinary tract disorders. Ectopic pregnancy (EP), pelvic inflammatory disease (PID), and ruptured ovarian cysts are the most common gynecological causes for acute pelvic pain and their diagnosis can be challenging.

METHODS

Patient history, clinical examination, and blood tests as well as patient age and potential pregnancy status help to establish the correct diagnosis. While sonography (US) remains the primary imaging modality of choice, computed tomography (CT) plays an important role in patients with indeterminate US evaluation and for treatment planning.

CONCLUSION

Diagnostic imaging is pivotal to differentiate potentially life- and fertility-threatening conditions from those that can be treated conservatively. Profound knowledge of the most common gynecological pathologies allows prompt and correct radiological diagnosis and assists in proper treatment planning.

Clinical-epidemiological profile of acute appendicitis: retrospective analysis of 638 cases

OBJECTIVE

to describe the clinical and epidemiological profile of acute appendicitis (AA) of the patients treated at a referral center in the Juiz de Fora macro-region, Minas Gerais State, Brazil.

METHODS

we conducted a retrospective, observational study in the Dr. Mozart Geraldo TeixeiraEmergency Hospital. We selected 638 patients diagnosed with AA, and analyzed the variables gender, age, evolutionary phase, length of hospital stay, pathological diagnosis, use of antibiotics, use of drains, complications and mortality.

RESULTS

AA was more prevalent in young adults (19-44 years) and males (65.20%). The mean hospital stay was seven days and phase II was the most prevalent. We found the histopathological diagnosis of primary tumor of the appendix in six patients (0.94%), adenocarcinoma being the most common histologic type (66.7%). Regarding the use of antibiotics, 196 patients underwent antibiotic prophylaxis and 306 received antibiotic therapy. Eighty-one patients used some kind of drain, for an average of 4.8 days. Seventeen patients died (2.67%), predominantly males (70.59%), with mean age of 38.47 years.

CONCLUSION

AA has a higher prevalence in males and young adults. The length of stay is directly associated with the evolutionary phase. The most common complication is infection of the surgical site. Mortality in our service is still high when compared with developed centers.

OBJETIVO

avaliar a epidemiologia e os resultados do tratamento cirúrgico de doentes portadores de graus III e IV, mais avançados, da Síndrome de Mirizzi (SM) de acordo com a classificação de Csendes.

MÉTODOS

estudo retrospectivo, de corte transversal através da revisão de prontuários de 13 pacientes portadores de graus III e IV da SM operados de dezembro de 2001 a setembro de 2013, entre 3691 colecistectomias realizadas neste período.

RESULTADOS

a incidência da SM foi 0,6% (23 casos) e os graus III e IV perfizeram 0,35% deste número. Houve um predomínio de tipo IV (12 casos). O diagnóstico pré-operatório foi possível em 53,8% dos casos. A conduta preferencial foi derivação biliodigestiva (10 casos) e foi optado por drenagem com tubo "T" e sutura da via biliar em três ocasiões especiais. Três pacientes apresentaram fístula biliar resolvida com conduta expectante e um caso de coleperitônio necessitou reoperação. No seguimento ambulatorial dos pacientes que realizaram a anastomose biliodigestiva (oito), 50% estão assintomáticos, 25% apresentaram estenose da anastomose e 25% perderam seguimento. O tempo médio de acompanhamento foi 41,8 meses.

CONCLUSÃO

de incidência baixa e de diagnóstico pré-operatório em apenas metade dos casos, a SM em graus avançados tem na anastomose biliodigestiva sua melhor conduta, porém não isenta de morbimortalidade.
