Review
The vagina is an essential component of the female reproductive system and is responsible for providing female sexual satisfaction. Vaginal smooth muscle contraction plays a crucial role in various physiological processes, including sexual arousal, childbirth, and urinary continence. In pathophysiological conditions, such as pelvic floor disorders, aberrations in vaginal smooth muscle function can lead to urinary incontinence and pelvic organ prolapse. A set of cellular and sub-cellular physiological mechanisms regulates the contractile properties of the vaginal smooth muscle cells. Calcium influx is a crucial determinant of smooth muscle contraction, facilitated through voltage-dependent calcium channels and calcium release from intracellular stores. Comprehensive reviews on smooth muscle biophysics are relatively scarce within the scientific literature, likely due to the complexity and specialized nature of the topic. The objective of this review is to provide a comprehensive description of alterations in the cellular physiology of vaginal smooth muscle contraction. The benefit associated with this particular approach is that conducting a comprehensive examination of the cellular mechanisms underlying contractile activation will enable the creation of more targeted therapeutic agents to control vaginal contraction disorders.

Chronic prostatitis/chronic pelvic pain syndrome CP/CPPS is a rather common condition and in recent years many studies have shown contradictory results regarding its impact on semen quality. This prospective cohort study set out to investigate how CP/CPPS affected the parameters of semen in a prospective cohort of patients compared with the WHO 2021 reference group. From 2013 to 2022, a total of 1071 patients with suspicion of CP/CPPS received a comprehensive andrological examination. Complete semen analysis was carried out in compliance with WHO 2010 guidelines, comparing every study population semen variable to the WHO 2021 reference group (n~3500). All evaluated semen parameters had median values that fell within a normal range. Nonetheless, approximately 25% of patients had values for each semen variable that were lower than the WHO reference group's fifth percentile. In particular, bacteriospermia was associated with a negative impact on semen volume. This is the largest study that compares all standard semen parameters in patients suffering from CP/CPPS to WHO 2021 reference values. It provides evidence of an impairment of conventional semen parameters.

A 7-year-old farmed white-tailed deer doe was transported to a Levy County, Florida property and began to decline in health, exhibiting weight loss and pelvic limb weakness. The doe prematurely delivered live twin fawns, both of which later died. The doe was treated with corticosteroids, antibiotics, gastric cytoprotectants, and B vitamins but showed no improvement. The doe was euthanized, and a post mortem examination was performed under the University of Florida's Cervidae Health Research Initiative. We collected lung tissue after the animal was euthanized and performed histological evaluation, using H&E and Ziehl-Neelsen (ZN) staining, and molecular evaluation, using conventional PCR, followed by Sanger sequencing. The microscopic observations of the H&E-stained lung showed multifocal granuloma, while the ZN-stained tissue revealed low numbers of beaded, magenta-staining rod bacteria inside the granuloma formation. Molecular analysis identified the presence of . This isolation of a non-tuberculous in a white-tailed deer emphasizes the importance of specific pathogen identification in cases of tuberculosis-like disease in farmed and free-ranging cervids. We report the first case of infection in a farmed white-tailed deer () in Florida. Although cases are sporadic in white-tailed deer, it is important to maintain farm biosecurity and prevent farmed cervids from contacting wildlife to prevent disease transmission.

Review
BACKGROUND
Wandering spleen is a rare clinical entity in which the spleen is hypermobile and migrate from its normal left hypochondriac position to any other abdominal or pelvic position as a result of absent or abnormal laxity of the suspensory ligaments (Puranik in Gastroenterol Rep 5:241, 2015, Evangelos in Am J Case Rep. 21, 2020) which in turn is due to either congenital laxity or precipitated by trauma, pregnancy, or connective tissue disorder (Puranik in Gastroenterol Rep 5:241, 2015, Jawad in Cureus 15, 2023). It may be asymptomatic and accidentally discovered for imaging done for other reasons or cause symptoms as a result of torsion of its pedicle and infarction or compression on adjacent viscera on its new position. It needs to be surgically treated upon discovery either by splenopexy or splectomy based on whether the spleen is mobile or not.
CASE PRESENTATION
We present a case of 39 years old female Ethiopian patient who presented to us complaining constant lower abdominal pain especially on the right side associated with swelling of one year which got worse over the preceding few months of her presentation to our facility. She is primiparous with delivery by C/section and a known case of HIV infection on HAART. Physical examination revealed a right lower quadrant well defined, fairly mobile and slightly tender swelling. Hematologic investigations are unremarkable. Imaging with abdominopelvic U/S and CT-scan showed a predominantly cystic, hypo attenuating right sided pelvic mass with narrow elongated attachment to pancreatic tail and absent spleen in its normal position. CT also showed multiple different sized purely cystic lesions all over both kidneys and the pancreas compatible with AD polycystic kidney and pancreatic disease. With a diagnosis of wandering possibly infarcted spleen, she underwent laparotomy, the finding being a fully infarcted spleen located on the right half of the upper pelvis with twisted pedicle and dense adhesions to the adjacent distal ileum and colon. Release of adhesions and splenectomy was done. Her post-operative course was uneventful.
CONCLUSION
Wandering spleen is a rare clinical condition that needs to be included in the list of differential diagnosis in patients presenting with lower abdominal and pelvic masses. As we have learnt from our case, a high index of suspicion is required to detect it early and intervene by doing splenopexy and thereby avoiding splenectomy and its related complications.

OBJECTIVE
Primary care practitioners are crucial to engaging people in Australia's national cervical screening program. From July 2022, practitioners have been able to offer all screen-eligible people the choice to collect their own self-collected sample; an option introduced to increase equity. This study explored how practitioners are intending to incorporate universal access to self-collection into their clinical care.
METHODS
Semi-structed interviews with 27 general practitioners, nurses, and practice managers from 10 practices in Victoria, Australia conducted between May and August 2022. Interviews were deductively coded, informed by the Consolidated Framework for Implementation Research. The Diffusion of Innovations theory was used to categorise intention to provide self-collection.
RESULTS
Participants were supportive of universal access to self-collection, citing benefits for screen-eligible people and that it overcame the limited adaptability of the previous policy. Most participants' practices (n = 7, 70%) had implemented or had plans to offer the option for self-collection to all. Participants deliberating whether to provide universal access to self-collection held concerns about the correct performance of the self-test and the perceived loss of opportunity to perform a pelvic examination. Limited time to change practice-level processes and competing demands within consultations were anticipated as implementation barriers.
CONCLUSIONS
The extent to which self-collection can promote equity within the program will be limited without wide-spread adoption by practitioners. Communication and education that addresses concerns of practitioners, along with targeted implementation support, will be critical to ensuring that self-collection can increase participation and Australia's progression towards elimination of cervical cancer.

INTRODUCTION
Pelvic apophyseal avulsion fractures are uncommon injuries that frequently affect adolescents while participating in sports. This occurs because the enthesis cannot withstand the tractional force applied because the apophysis has not yet fully fused. Due to its complex muscular structure, being the origin of several muscles that cross two lower extremity joints, the pelvis has an increased risk for such injuries. The diagnosis of pelvic avulsion injuries depends heavily on imaging. The best way to detect soft-tissue changes, including tendon or muscle strain, bone marrow edema, hematomas, and soft tissue avulsion injuries, is with an magnetic resonance imaging . It is also the best at showing tendon retraction and can help the clinician spot patients who might benefit from surgical treatment.
CASE REPORT
We report six cases of adolescents professional footballers that suffered avulsion injuries while playing football. The patients had painfully restricted hip range of motion and were unable to bear weight. Some of them on physical examination felt pain at the palpation of the injured area. Magnetic resonance revealed apophysis growth plate avulsion with or without displaced bone fragments that were treated conservatively with an excellent clinical and radiological outcome.
CONCLUSION
For an accurate diagnosis of pelvic avulsion injuries and clinical management, it is important that everyone caring for this patient population is aware of the common injury mechanisms, radiographic findings, and available treatments.

Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors that arise in the muscular or submucosal layers of the gastrointestinal tract. Extra-gastrointestinal stromal tumors (EGISTs) are rare primary entities that develop outside the digestive tract which are histologically and immunologically similar to GISTs. We present the case of a 52-year-old female diagnosed with a primary EGIST arising in the small bowel mesentery four months after undergoing hormone therapy for multiple uterine myomas. Transvaginal ultrasonography and MRI revealed a pelvic mass suspected to be a GIST. The patient was treated with laparoscopic-assisted partial resection of the small bowel. Histopathological examination of the surgical specimen confirmed the diagnosis of an EGIST. Imatinib treatment was initiated, and no clinical evidence of recurrence or metastasis was detected postoperatively. Because EGISTs are extremely rare, the differences between EGISTs and GISTs, the degree of malignancy, and prognosis have not been fully investigated. Further studies are needed to accumulate additional cases. The present case shows that laparoscopic-assisted excision can be successfully used to manage EGISTs.

BACKGROUND
The findings of pre-operative investigations help to identify risk factors that may affect the course of surgery or post-operative recovery by contributing to informed consent conversations between the surgical team and the patient, as well as guiding surgical and anesthetic planning. Certainly, preoperative tests are valuable when they offer additional information beyond what can be gathered from a patient's history and physical examination alone. Preoperative testing practices differ significantly among hospitals, and even within the same hospital, clinicians may have varying approaches to requesting tests. This study aimed to investigate preoperative testing practices and compare them with the latest guidelines from the National Institute for Health and Care Excellence (NICE).
METHODS
This three-month institutionally based study was carried out at the Debre Tabor Comprehensive Specialized Hospital from May 1 to July 30, 2023, including individuals aged 16 years and older who were not pregnant and had undergone elective surgery in the gynecological, orthopedic, and general units. Data on the sociodemographic characteristics, the existence of comorbidities, the invasiveness of surgery, and the tests taken into consideration by the guideline were gathered using a self-administered questionnaire. After rigorously analyzing and revising the results of preoperative investigation approaches, we compared them to the standard of recommendations. Moreover, the data was analyzed and graphically presented using Microsoft Excel 2013.
RESULTS
During the data collection period, 247 elective patients underwent general, orthopedic, and gynecological operations. The majority of patients, 107 (43.32%), were between the ages of 16 and 40 and had an American Society of Anesthesiologists (ASA) class one (92.71%). 350 investigations were requested in total. Of these, 71 (20.28%) tests were ordered without a justified reason or in contravention of NICE recommendations.
CONCLUSIONS
In our hospital's surgical clinical practice, unnecessary preoperative testing is still common, especially when it comes to organ function tests, electrocardiograms (ECGs), and complete blood counts (FBCs). When deciding whether preoperative studies are required, it is critical to consider aspects including a complete patient history, a physical examination, and the invasiveness of the surgery.

OBJECTIVE
This report summarizes the characteristics of a series of 8 recent (2020-2022) patients with abdominal wall endometriosis (AWE) who underwent laparoscopic surgery. The feasibility and advantages of laparoscopy in the treatment of AWE are set out.
METHODS
The clinical data of the 8 AWE patients were retrospectively analysed. Basic clinical characteristics, operation details and postoperative details were collected and analysed.
RESULTS
Laparoscopic treatment was successful in all 8 cases. The mean operation time was 212.13 ± 48.16 min, the mean estimated blood loss was 25.00 ± 11.18 ml, and the mean postoperative hospital stay was 5.25 ± 1.39 days. 7 of the patients were found to have concomitant pelvic endometriosis, and 1 patient was found to have concealed inguinal hernias during surgery. Concomitant laparoscopic surgery for pelvic lesions was performed, including electrocautery or lesion resection of the pelvic endometriosis lesions in 7 patients, uterine fibroidectomy in 2 patients, high ligation of the hernia sac in 1 patient and endometrial biopsy under hysteroscopy in 1 patient. Endometrial-like tissue was confirmed by postoperative pathological examination of resected AWE lesions in all patients. There were no intraoperative or postoperative complications. The mean follow-up time was 18.75 ± 3.96 months, and no recurrence of AWE was found.
CONCLUSION
Laparoscopic surgery is a safe, effective and feasible treatment option for AWE patients and has the advantages of simultaneous diagnosis and treatment of other pelvic lesions.

BACKGROUND
Open reduction and plate fixation is a standard procedure for treating traumatic symphyseal disruptions, but has a high incidence of implant failure. Several studies have attempted to identify predictors for implant failure and discussed its impact on functional outcome presenting conflicting results. Therefore, this study aimed to identify predictors of implant failure and to investigate the impact of implant failure on pain and functional outcome.
METHODS
In a single-center, retrospective, observational non-controlled cohort study in a level-1 trauma center from January 1, 2006, to December 31, 2017, 42 patients with a plate fixation of a traumatic symphyseal disruption aged ≥ 18 years with a minimum follow-up of 12 months were included. The following parameters were examined in terms of effect on occurrence of implant failure: age, body mass index (BMI), injury severity score (ISS), polytrauma, time to definitive treatment, postoperative weight-bearing, the occurrence of a surgical site infection, fracture severity, type of posterior injury, anterior and posterior fixation. A total of 25/42 patients consented to attend the follow- up examination, where pain was assessed using the Numerical Rating Scale and functional outcome using the Majeed Pelvic Score.
RESULTS
Sixteen patients had an anterior implant failure (16/42; 37%). None of the parameters studied were predictive for implant failure. The median follow-up time was six years and 8/25 patients had implant failure. There was no difference in the Numerical Rating Scale, but the work-adjusted Majeed Pelvic Score showed a better outcome for patients with implant failure.
CONCLUSION
implant failure after symphyseal disruptions is not predictable, but appears to be clinically irrelevant. Therefore, an additional sacroiliac screw to prevent implant failure should be critically discussed and plate removal should be avoided in asymptomatic patients.
