Context: Sport-specific adaptations in shoulder rotation range of motion (ROM) and the relationship with humeral torsion have been described in overhead-throwing sports. However, information is lacking for other shoulder-loading sports such as field hockey. Therefore, this study's purpose was to evaluate humeral torsion in elite, male field hockey players and explore its association with shoulder ROM. Design: Cross-sectional study. Methods: Twenty-five male, elite field hockey players were included. Humeral torsion and shoulder external and internal rotation ROM were evaluated bilaterally by ultrasound and an inclinometer smartphone application, respectively. Results: Field hockey players showed a significantly increased humeral retroversion on the dominant compared with the nondominant side (P <.001; Cohen d = 1.75), along with a significantly increased external (P =.004; Cohen d = −0.64) and decreased internal rotation ROM (P =.003; Cohen d = 0.65). This finding illustrates a shift in total shoulder rotational ROM arc. Correlation analysis showed a significant moderate association between the increased humeral retroversion and decreased internal rotation ROM on the dominant side (r =.523). Conclusions: Elite male field hockey athletes show sport-specific adaptations regarding humeral torsion and shoulder rotation ROM, similar to throwing athletes. These findings increase our insight into the field hockey athlete's shoulder, which is essential to optimize performance and assist in correctly interpreting shoulder rotational ROM measurements.

Background: Controversy exists regarding the origin of femoral torsion, and specific treatment rules regarding the optimal position of femoral osteotomy in patients with recurrent patellar subluxation and excessive femoral torsion are scarce. Purpose: To establish a novel classification system for such patients, and to compare clinical and radiological outcomes after distal derotational femoral osteotomy (DDFO) between femoral torsion at proximal (neck and shaft) and distal levels. Methods: Between January 2014 and June 2019, patients who underwent DDFO were retrospectively reviewed. The segmental torsion analysis was performed to establish a novel classification system, and classify included patients into two groups: 35 patients in proximal torsion group and 38 patients in distal torsion group. These patients were followed-up for at least 3 years. Clinical evaluations included functional outcomes, physical examinations, quality of life, activity level, satisfaction, and complications. Radiological outcomes included patellofemoral osteoarthritis, congruence, and alignment. Results: Type I was defined as the proximal torsion. Type II was defined as the distal torsion. Proximal torsion group had lower postoperative femoral torsion (12.6 ± 2.6° vs. 14.8 ± 3.6°; P =.004) and higher surgical correction angle (21.6 ± 5.0° vs. 19.1 ± 3.0°; P =.009). All clinical and radiological outcomes improved significantly in both groups, but proximal torsion group had significantly higher quality of life (EQ-5D-5L: 0.96 ± 0.06 vs. 0.91 ± 0.07; P =.003. EQ-VAS: 92.0 ± 6.0 vs. 88.7 ± 5.8; P =.021) and Tegner activity score (5.2 ± 1.5 vs. 4.5 ± 1.4; P =.040), and fewer patellofemoral osteoarthritis (8.6% vs. 26.3%; P =.048). Two patients in the distal torsion group had subjective patellar instability. The percentage of patients with anterior knee pain was higher in the distal torsion group. Conclusion: A novel classification system for patients with recurrent patellar subluxation and excessive femoral torsion based on segmental femoral torsion analysis was established. DDFO was more appropriate for patients with proximal torsion, yielding higher surgical correction angle, and better clinical and radiological outcomes. Study design: Cohort study; Level of evidence, 3. [ABSTRACT FROM AUTHOR]

A 35‐year‐old woman (gravida 1, para 0) was admitted to our hospital at 28 weeks' gestation with vaginal bleeding from placenta previa. Severe fetal bradycardia was observed during fetal heart rate monitoring. Ultrasonography showed widely dilated veins on the fetal surface of the placenta and an extraordinarily low umbilical artery peak systolic velocity in the Doppler study. Umbilical cord torsion was suspected. On the subsequent day, we performed a cesarean section due to worsening fetal heart rate patterns. Umbilical artery blood gas analysis indicated severe acidemia (pH 7.063), and umbilical cord torsion was confirmed at the placental cord insertion site. Diagnosing UCT prenatally is challenging; however, it can be suspected by scanning for the widely dilated veins on the fetal placental surface, termed as the "Sunset Sign," an abnormally low umbilical artery peak systolic velocity, and other fetal Doppler abnormalities.

Background: The relationship between hip rotational abnormalities and hip labral size has not been fully investigated. Purposes: To (1) examine the correlation between rotational abnormalities of the hip and labral size, while also identifying other predictive values for hip labral size, and (2) explore whether femoral torsion will lead to increased labral size. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 180 patients (180 hips) with femoroacetabular impingement syndrome (FAIS) (mean age, 36.81 ± 10.17 years; 67 male, 113 female) who underwent hip arthroscopic surgery between January 2021 and May 2022 were included. The femoral version (FV), acetabular version, and combined version angles were measured on computed tomography, and the labral length and height at the 12-o'clock and 3-o'clock positions were measured on magnetic resonance imaging. The hips were categorized into 3 groups based on FV angle: small (SFV; <10°); moderate (MFV; ≥10° and ≤20°), and large (LFV; >20°), and group comparisons were performed. Linear correlation and regression analysis were employed. Results: Predictive factors for labral length were FV angle (β = 0.298; P =.02), sex (β = −0.302; P <.001), and age (β = −0.169; P =.016) at 3 o'clock and lateral center-edge angle (LCEA; β = −0.208; P =.005) and age (β = −0.186; P =.011) at 12 o'clock. FV angle was positively correlated with labral length at 3 o'clock (r = 0.267; P <.001) and negatively correlated with age (r = −0.222; P =.003) and female sex (r = −0.202; P =.006). LCEA (r = −0.227; P =.002) and age (r = −0.205; P =.006) were negatively correlated with labral length at 12 o'clock. Labral length at 3 o'clock was significantly different between the LFV (n = 49 hips), MFV (n = 65 hips), and SFV (n = 66 hips) groups (9.85 ± 2.28, 8.89 ± 2.44, and 8.30 ± 2.05 mm, respectively; P =.027 for LFV vs MFV; P <.001 for LFV vs SFV). Conclusion: Patients with FAIS who exhibited a higher FV angle were at a greater likelihood of having a larger anterior labral length. Increased femoral anteversion and decreased LCEA, male sex, and younger age were significantly associated with longer hip labral length. [ABSTRACT FROM AUTHOR]

Middle lobe torsion (MLT) is an unusual complication in lung surgery that is usually associated with upper lobe lobectomy and rarely develops postlower lobectomy. In the case of MLT, urgent surgical intervention is required to decrease the risk of mortality and morbidity, and diagnosis is challenging due to the nonspecific symptoms of MLT. In this article, we present a case of a recurring lung abscess treated by the right lower lobectomy, complicated by the right MLT and to our knowledge MLT consider rarest complication postright lower lobectomy.

In this case report, we present an unusual clockwise torsion of left colon around mesenteric root in a 10‐month‐old Arab filly, highlighting the clinical presentation, diagnostic approach and successful surgical intervention. A 10‐month‐old Arab filly weighing approximately 250 kg was referred with signs of acute abdominal pain. The history revealed anorexia, restlessness and severe abdominal pain that had begun the previous day. The local practitioner had previously administered flunixin meglumine, an analgesic, but it proved ineffective in relieving the pain. Upon physical examination, the filly exhibited sweating, a body temperature of 38.5°C, tachycardia (65 beats per minute) and tachypnea (25 breaths per minute). Due to the severity of the colic and the lack of response to the conservative treatments, surgical intervention was deemed necessary. An exploratory midline celiotomy was performed to evaluate the abdominal organs. During the examination, no obvious primary lesions were identified in the evaluated organs. However, a restriction in exteriorizing the left colon's length was observed. Further examination revealed an unusual clockwise torsion of the left colon that displaced in left to the right side around the mesenteric root; thereby, pelvic flexure was located in the normal anatomical position with a short length. To the best of our knowledge, this is the first reported case of clockwise torsion and an atypical displacement of the left colon in horses. The surgical correction of the displacement was successfully performed. The filly showed improvement post‐surgery and did not exhibit any complications during the recovery period.

Objective: Ovarian torsion (OT) represents a severe gynecological emergency in female pediatric patients, necessitating immediate surgical intervention to prevent ovarian ischemia and preserve fertility. Prompt diagnosis is, therefore, paramount. This retrospective study set out to assess the utility of combined clinical, ultrasound, and laboratory features in diagnosing OT. Methods: The authors included 326 female pediatric patients aged under 14 years who underwent surgical confirmation of OT over a five-year period. Logistic regression analysis was employed to pinpoint factors linked with OT, and the authors compared clinical presentation, laboratory results, and ultrasound characteristics between patients with OT (OT group) and without OT (N-OT group). The authors conducted receiver operating characteristic (ROC) curve analysis to gauge the predictive capacity of the combined features. Results: Among 326, OTwas confirmed in 24.23 % (79 cases) of the patients. The OT group had a higher incidence of prenatal ovarian masses than the N-OT (22 cases versus 7 cases) (p < 0.0001). Similarly, the authors observed significant differences in the presence of lower abdominal pain, suspected torsion on transabdominal ultrasound, and a high neutrophil-lymphocyte ratio (NLR > 3) between the OT and non-OT groups (p > 0.05). Furthermore, when these parameters were combined, the resulting area under the curve (AUC) was 0.868, demonstrating their potential utility in OT diagnosis. Conclusion: This study demonstrates a prediction model integrating clinical, laboratory, and ultrasound findings that can support the preoperative diagnosis of ovarian torsion, thereby enhancing diagnostic precision and improving patient management. Future prospective studies should concentrate on developing clinical predictive models for OT in pediatric patients. [ABSTRACT FROM AUTHOR]

Understanding the implications of decreased femoral torsion on gait and running in children and adolescents might help orthopedic surgeons optimize treatment decisions. To date, there is limited evidence regarding the kinematic gait deviations between children with decreased femoral torsion and typically developing children, as well as the implications of the same on the adaptation of walking to running. A three-dimensional gait analysis study was undertaken to compare gait deviations during running and walking among patients with decreased femoral torsion (n = 15) and typically developing children (n = 11). Linear mixed models were utilized to establish comparisons within and between the two groups and investigate the relationship between clinical examination, spatial parameters, and the difference in hip rotation between running and walking. Patients exhibited increased external hip rotation during walking in comparison to controls, accompanied by higher peaks for the same as well as for knee valgus and external foot progression angle. A similar kinematic gait pattern was observed during running, with significant differences noted in peak knee valgus. In terms of variations from running to walking, patients internally rotated their initially externally rotated hip by 4°, whereas controls maintained the same internal hip rotation. Patients and controls displayed comparable kinematic gait deviations during running compared to walking. The passive hip range of motion, torsions, and velocity did not notably influence the variation in mean hip rotation from running to walking. This study underlines the potential of 3D gait kinematics to elucidate the functional implications of decreased FT and, hence, may contribute to clinical decision making. [ABSTRACT FROM AUTHOR]

PURPOSE: The purpose of this study was to evaluate the amount of sensitivity and specificity of the slit-light (SL) method in the diagnosis of ocular cyclotorsion. MATERIALS AND METHODS: One hundred and twenty eyes of 60 individuals (10-60 years old), with mean visual acuity of 0.08 ± 0.14 LogMAR, were divided into two groups (normal and torsion groups). Individuals without ocular motility disorder were selected as normal and patients with extraocular motility disorders and oblique muscle dysfunctions as the torsion group. The sensitivity and specificity of SL in the diagnosis of ocular torsion were measured by masked investigators and compared to fundus photography (FP). Inter- and intraobserver variability of these techniques was also determined. RESULTS: The amounts of sensitivity and specificity of SL, measured by the first examiner, were 60% and 92% for intorsion and 50% and 96% for extorsion assessment, respectively. These amounts were 53% and 95% for intorsion, and 54% and 97% for extorsion by the second examiner. The contingency coefficient between the two examiners was 68.6% for SL. This amount was 61% between FP and SL for the first examiner and 63% for the second. The contingency coefficient for the repeatability of SL was 72.2% for the first examiner and 75.7% for the second. This amount was 71.2% between the two examiners. CONCLUSION: SL can be considered a useful method for the diagnosis of cyclotorsion. [ABSTRACT FROM AUTHOR]

To describe the clinical presentation, diagnosis, perioperative management and the short‐ and long‐term outcomes of a dog diagnosed with pancreatic torsion. A 3‐month‐old female intact Bernese Mountain dog presented for an acute onset of vomiting, anorexia and abdominal pain. Abdominal ultrasonography showed a hypoechoic mass effect cranial to the stomach. A pancreatic torsion was diagnosed during exploratory laparotomy and treated with partial pancreatectomy. Histopathology confirmed pancreatic torsion. The patient recovered uneventfully and pancreatic function and inflammation testing that was performed 14 months postoperatively showed no evidence of ongoing dysfunction. This is the first report that demonstrates long‐term follow‐up with pancreatic function testing in a patient who had a partial pancreatectomy due to pancreatic torsion. There was no evidence of long‐term pancreatic dysfunction due to partial pancreatectomy secondary to pancreatic torsion. Additionally, this is the youngest patient with pancreatic torsion to be described in the veterinary literature. [ABSTRACT FROM AUTHOR]

Background: Wandering spleen (or ectopic spleen) refers to a hyper-mobile spleen resulting in its displacement from the normal anatomical position to usually in the lower abdominal or pelvic cavity. While ultrasound is often the first radiological modality used, Computed Tomography (CT) shows a clear picture and aides to reach a diagnosis. In circumstances where appropriate imaging modalities are not available, or the operator is inexperienced, diagnosis of wandering spleen can be missed. Case presentation: A 22-nulligravida unmarried Sindhi female had presented to the Emergency Room (ER) with a 5-day history of intermittent severe lower abdominal pain. An ultrasound at a local practitioner had suggested an ovarian cyst. Ultrasound-pelvis and later CT scan at our facility reported an enlarged wandering spleen with torsion of its pedicle and infarction. Exploratory laparotomy with splenectomy was done. An enlarged wandering spleen was found with torsion of the splenic vein and thrombosed arterial supply from omentum wrapped over the mass. The patient developed thrombocytosis post-surgery but otherwise did well and was discharged after 2 days. Conclusion: Splenic torsion secondary to a wandering spleen can be challenging to diagnose, especially in resource limited settings where ultrasound might be the only modality available. Timely diagnosis and proper intervention are key to saving the life and the spleen. [ABSTRACT FROM AUTHOR]

Objective: Rare disease Background: Diffuse intestinal lipomatosis is a rare condition that infiltrates mature fatty tissue into the intestinal submucosa and subserosa of the small or large intestine and can present with intestinal obstruction or torsion. This report is of the case of a 58-year-old woman who had acute torsion of the small bowel due to diffuse small intestinal lipomatosis. Case Report: A 58-year-old woman, who was otherwise in good health, arrived at our Emergency Department experiencing sudden, intense pain in the lower abdomen. She also reported abdominal swelling, feelings of nausea, vomiting, and reduced ability to defecate for at least 2 days. The next morning, contrast-enhanced abdominal computed tomography (CT) scan was performed, showing diffuse thickening of the small intestinal wall with hypodensity, fatty density, lumen narrowing, and wall thinning. The small intestine demonstrated a whirlpool-like distribution in the lower right abdomen and localized thickening of the small intestinal wall, suggesting acute intestinal torsion. An hour later, an emergency operation was performed to remove part of the small intestine. Three days later, pathological results showed a thin intestinal wall, expansion of the mucosal layer and submucosa, and hyperplasia of adipose tissue. Conclusions: This report presents a rare case of torsion and small bowel obstruction caused by diffuse intestinal lipomatosis and focuses on the abdominal enhanced CT scan, which showed diffuse thickening of the small intestine, with multiple areas of fat density and torsion of the small intestine in the right lower abdomen. Histopathology is also presented, with the result showing intestinal lipomatosis. [ABSTRACT FROM AUTHOR]

Background: Uterine torsion in dairy cows generally occurs during gestation. However, some cows develop uterine torsion after calving, and the details of which are not known. Objectives: The present study aimed to investigate the clinical signs, epidemiological characteristics and treatment methods of 23 cases of post‐partum uterine torsion in dairy cows. Methods: A total 23 Holstein dairy cows diagnosed with post‐partum uterine torsion were investigated. The clinical signs and epidemiological information were reviewed from medical records. The diagnostic methods, findings and treatment method of each case were recorded. Results and conclusions: Post‐partum uterine torsion is typically observed in dairy cows 9.6 ± 3.7 days after calving. That is, 21 out of 23 [91%] were multiparous and 8 out of 23 [34.8%] were characterised by multiple births. The retained placenta was observed in at least 20 out of 23 [87%], and a standing abnormality was observed in 18 out of 23 [78.3%]. The clinical signs observed in all cases included anorexia and accumulation of lochia and gas with a putrid odour in the uterus. In addition, eight and nine cases treated with the transrectal manual method and laparotomy, respectively, were cured. In conclusion, post‐partum uterine torsion in dairy cows developed around 10 days after calving, with anorexia and accumulation of lochia and gas with a putrid odour in the uterus. It has been suggested that torsion can be reconstructed using the transrectal manual method or laparotomy. [ABSTRACT FROM AUTHOR]

Current standard total shoulder pegged glenoid component designs have a high rate of loosening, which accounts for the most common long-term reason for surgical failure. Glenoid design, method of fixation, and implantation version all play a role in component stability. This study aimed to evaluate the biomechanical stability of a novel circular glenoid with peripheral ring fixation and compare to a standard anchor pegged glenoid both directly and to historical biomechanical data. Additionally, we compared the estimated bone removal for the glenoid design types. Biomechanical testing was performed to assess the circular glenoid with peripheral ring fixation with regards to stability and resistance to "rocking horse" effect, torsional loosening, resistance to torque dissociation, and axial pullout strength. This was compared directly (pullout strength) and to historical ("rocking horse") biomechanical data obtained for a standard anchor pegged glenoid. A 3D Computer-Aided Design model of five different scapula sizes and shapes was also utilized to estimate volume bone removed when using implant specific prep instrumentation for each glenoid system. Tensile displacement of the worst-case ring fixation component (size medium) after dynamic rocking was 0.060 mm requiring an average peak torque of 6.21N-m to dissociate the glenoid. The ring fixation component demonstrated a mean pullout strength of 1367 N compared with 645 N for the standard anchor pegged glenoid component. The ring fixation component revealed no loosening when placed under torsional stress. The peripheral ring fixation glenoid preparation on average removed 45% less bone than a standard anchor pegged glenoid. The circular glenoid with peripheral ring fixation demonstrated superior maximum pullout strength and more bone preservation with glenoid preparation when compared to the standard pear-shaped, pegged glenoid components. Compared to published standard pegged glenoid component controls, the glenoid with peripheral ring fixation demonstrated diminished "rocking horse" displacement. Despite the circular anchor ring design, there was no evidence of loosening under torsional stress. Initial biomechanical data is overall promising for this novel glenoid design.

An epididymal cyst (EC) is a benign lesion. It arises due to cystic degeneration of the epididymis. The torsion of it is extremely rare. The usual presentation of the cyst is asymptomatic scrotal swelling. The swelling has a lobulated surface and feels like a bunch of grapes. The huge EC is rare and moreover, it is associated with torsion-rarest presentation. [ABSTRACT FROM AUTHOR]

Gallbladder torsion is a rare cause of acute surgical abdomen. Early recognition and surgical intervention are important for reducing complications and improving postoperative patient outcomes, but standard imaging and laboratory evaluation typically are indistinguishable from those of acute cholecystitis. This article describes a patient with gangrenous cholecystitis secondary to torsion and summarizes recommendations for evaluation and management. [ABSTRACT FROM AUTHOR]

Background: Transabdominal ultrasound (US) is first-line imaging to evaluate ovaries in girls presenting to the emergency department (ED) with suspected ovarian torsion. Ovaries may be difficult to visualize sonographically; therefore, prompt diagnosis using US alone can be challenging. Rapid MRI as first-line imaging may help streamline patient throughput, especially with increasing MRI availability in the ED. Objective: To assess feasibility of rapid MRI for diagnosis of ovarian torsion. Materials and Methods: A retrospective, single-center IRB approved study of MRI performed in female pediatric patients presenting with abdominopelvic pain from August 2022 to January 2023. Imaging occurred according to one of three clinical pathways (US-first approach vs MRI-first approach vs US + MRI-second-line approach). A rapid three-sequence free-breathing MRI protocol was utilized. Frequency of ovarian torsion and secondary diagnoses was recorded. Length of MR scan time, time from ED arrival to time of diagnosis, and whether patient had US prior to MR exam were obtained. A historical cohort of patients with US only performed for assessment of ovarian torsion were evaluated for length of the US examination and time from ED arrival to time of diagnosis. Intervals were compared using the uncorrected Fisher's least significant difference and Turkey's multiple comparison tests. Results: A total of 140 MRI exams (mean age 14.6 years) and 248 historical US exams (mean age 13.5 years) were included. Of the patients with MRI, 41 (29%) patients were imaged with US + MRI and 99 (71%) imaged with MRI only; 4% (6/140) MR exams were suspicious for ovarian torsion, with one true positive case (1/6 TP) and 5 false positive cases (5/6 FP); 26.4% (37/140) of exams had secondary diagnoses. Median MRI scan time was 11.4 min (4.4) vs median historical US scan time was 24.1 min (19.7) (P<0.001). Median time from arrival in ED to MRI read was 242 (140). Median time from arrival in ED to US only read was 268 min (148). This was not a statistically significant difference when compared to the MRI only cohort. Conclusion: First-line MRI imaging for evaluation of ovarian torsion is a rapid and feasible imaging modality for female patients in the emergent setting. [ABSTRACT FROM AUTHOR]

Objectives: To analyze the clinical characteristics and risk factors related to necrosis of adnexal torsion (AT) and improve the application of ovarian-sparing surgery (OSS). Material and methods: Data of 142 patients with 144 surgically confirmed AT lesions between October 2011 and December 2021 were retrospectively analyzed. Results: The risk of torsion caused by tumors was higher than that caused by tumor-like lesions (p = 0.003). The incidence of right adnexal necrosis was higher than that of left adnexal necrosis (p = 0.03). There were no significant differences in adnexal necrosis or onset time (p = 0.29) between groups. The main risk factor for adnexal necrosis was the degree of torsion with a threshold of 510°. The size of adnexal mass and the degree of torsion increased linearly with age. The OSS rate was 59.7% for all patients, and 71.6% in the premenopausal women. No serious complications occurred in any of the patients. Conclusions: Age, histopathological type, adnexal size, degree of torsion, and pelvic anatomical structure are risk factors for AT and adnexal necrosis. There is no infinite correlation between adnexal necrosis and onset time. Adnexal size is the main risk factor for AT, and along with the risk of adnexal necrosis, increases with age. The degree of torsion is the main risk factor for adnexal necrosis, and torsional severity increases with age. OSS is safe and does not increase the incidence of postoperative complications.

Introduction. Isolated fallopian tube torsion (IFTT) has rarely been confirmed in sexually inactive adolescents, and preoperative diagnosis of IFTT is difficult because of the absence of specific symptoms. Therefore, pediatric patients with IFTT tend to be misdiagnosed before the surgery. Case. A 15-year-old female patient with no history of abdominal surgery or sexual intercourse presented with acute left lower abdominal pain and purpura. MRI revealed hydrosalpinx in the left adnexal region. Her abdominal pain had completely resolved at our examination; she was followed up as an outpatient. One month after the initial presentation, she experienced a large volume of watery discharge. Magnetic resonance imaging, which was performed every three months, showed a gradual decrease in the size of the hydrosalpinx; however, it persisted in the left adnexal region. She was counseled to receive laparoscopy to treat the hydrosalpinx, which was the most likely cause of the watery discharge. IFTT was detected during the laparoscopy, and left salpingectomy was performed for pathological evaluation of the persistent hydrosalpinx. Following laparoscopy, the patient's watery discharge was resolved. Pathological findings confirmed no signs of malignancy. Conclusion. Our current report highlighted watery discharge as an indicative symptom of IFTT. It is unclear whether IFTT induced the hydrosalpinx or vice versa. We presumed that the patient's hydrosalpinx occurred due to IFTT, because the patient complained watery discharge one month after the initial appearance, and noncongenital hydrosalpinx in adolescents, especially without a history of sexual intercourse, is a rare event. Clinicians should consider IFTT in patients presenting with unremitting watery discharge and hydrosalpinx, because IFTT may persist even after the pain disappears. [ABSTRACT FROM AUTHOR]

To compare the effects of backward (BW) and forward (FW) walking training on back geometry and mobility function in children with hemiparetic cerebral palsy (CP). Fifty-five children with hemiparetic CP participated in this study. They were randomly assigned into two groups. For 12 weeks, both groups got a conventional physical therapy program three days/week. Groups A and B got a specifically developed FW walking training (25 minutes/session) and a specially designed BW walking training (25 minutes/session), respectively. The trunk imbalance, lateral deviation, pelvic tilting, pelvic torsion, surface motion, and dynamic gait index of group B improved significantly more than group A (p <.05). Both groups showed significant improvements in all measured variables (p <.05). BW walking training might be considered as an effective therapy modality for improving back geometry and mobility function in hemiparetic CP children compared with FW walking training combined with a typical program.

Key Clinical Message: In this case, a patient experienced rare uterine torsion during pregnancy, detected by MRI. Diagnosis before Cesarean is helpful to achieve better outcomes, highlighting the importance of attention in high‐risk groups. Uterine torsion during pregnancy is a rare complication and its risk factors and diagnostic modalities have not yet been clearly defined. Here we present a case of uterine torsion due to unexpected pelvic adhesion. A 34‐years‐old primigravida patient underwent an emergency cesarean section for aggravated maternal preeclampsia symptoms at 34 + 0 weeks of gestation. Intraoperatively, after the baby was out, it was found that the uterus was rotated about 90 degrees to the right by dense pelvic adhesion in posterior uterine wall. In this patient, a rightward vaginal stretch was represented through a retrospective review of magnetic resonance imaging (MRI) before childbirth. To our knowledge, this is the first reported case of uterine torsion during pregnancy with MRI. Diagnosing uterine torsion in advance or paying attention to incisions during operative delivery will lead to better management in this condition and good perinatal outcomes. [ABSTRACT FROM AUTHOR]

An 8‐year‐old, spayed, female poodle presented with exercise intolerance, lethargy, respiratory distress, retching, hyporexia and diarrhoea. Thoracic radiographs revealed increased opacity in the left cranial thoracic region. The fifth and sixth ribs appeared to be bulging cranially to caudally, and CT and surgical exploration confirmed the presence of a thoracic wall defect in that area. CT showed abrupt occlusion of the bronchus that branches into the left cranial lobe and consolidation of the caudal segment of left cranial lung lobe, which led to the diagnosis of lung lobe torsion. A thoracotomy was performed, the twisted lung lobe was surgically excised, and the defect in the thoracic wall was repaired. Respiratory distress gradually improved after the surgery, and there were no identified complications within the 2‐year period following the procedure. Based on our literature search, this is the first reported case of lung lobe torsion caused by a thoracic wall defect in a dog. [ABSTRACT FROM AUTHOR]

This article presents a case of spontaneous autoamputation of ovary in a 46-year-old nulligravid woman with a history of rheumatoid arthritis and hypertension, who presented with secondary amenorrhea and white vaginal discharge. Despite an initial diagnosis of dermoid cyst based on ultrasound findings, subsequent laparoscopic surgery revealed a necrotized oval-shaped mass in the cul-de-sac, which was identified as the right ovary that had undergone torsion and autoamputation. This case highlights the diagnostic and therapeutic challenges associated with this uncommon presentation, which may be easily misdiagnosed. Clinicians should consider spontaneous autoamputation of ovary as a potential differential diagnosis in women presenting with adnexal masses, even if there is no prior history of abdominal pain.

We aimed at studying isolated Fallopian tube torsion (IFTT) in a relatively large cohort of women and to evaluate different features of IFTT in comparison to a large cohort of women with non-IFTT adnexal torsion (NIAT). This was a retrospective cohort study. We included women with surgically confirmed ovarian and/or Fallopian tube torsion between March 2011 and June 2020. Fifty-four cases of IFTT were surgically confirmed during the study period and were compared to 422 surgically confirmed NIAT. The rate of controlled ovarian hyperstimulation treatments, current pregnancy, and vomiting was lower in the IFTT group compared with the NIAT group. Cervical tenderness and vaginal discharge were more common in the IFTT group. Oedematous and enlarged ovaries were less common in the IFTT group. In multivariate regression analysis, the following factors were independently associated with IFTT: (i) vaginal discharge [adjusted odds ratio (aOR) 95% CI 8.16, 1.98–33.55]; (ii) cervical motion tenderness (aOR 95% CI 2.71, 1.01–7.29); (iii) fertility treatments (aOR 95% CI 0.26, 0.70–0.77); (iv) previous abdominal surgery (aOR 95% CI 0.46, 0.22–0.96); (v) vomiting (aOR 95% CI 0.38, 0.19–0.76); and (vi) enlarged ovary (aOR 95% CI 0.34, 0.18–0.65). In conclusion, we have identified factors positively and negatively associated with IFTT in a large cohort of women with adnexal torsion. [ABSTRACT FROM AUTHOR]

Postmenopausal ovarian masses are not uncommon. Most of them are malignant due to inflammation and adhesion with the surrounding structures; these masses are fixed and torsion is not a usual phenomenon. We present a 73-year-old postmenopausal woman, parity five and five living issues with an acute abdomen. The examination revealed a 28-30-week size abdominal pelvic mass, which was confirmed to be ovarian in origin, with characteristics that indicated torsion on ultrasound Doppler. She underwent an emergency laparotomy with a total abdominal hysterectomy and bilateral salpingo-ophrectomy. Histopathology confirmed the diagnosis of serous cystadenoma. Ovarian torsion is a crucial differential diagnosis in postmenopausal adnexal masses presenting with acute abdomen. A high index of suspicion is required to diagnose and promptly manage women to improve the outcome. [ABSTRACT FROM AUTHOR]

Introduction: There is an ongoing debate whether to perform orchiectomy or orchidopexy following testicular torsion (TT) in cases where the testis seems non-viable. The main problem is lack of objective criteria defining testicular viability. The aim of this study was to investigate the grade of injury in orchiectomy specimens obtained from cases of TT and its association with clinical findings. Methods: This multicenter retrospective study involved double-blinded reassessment of the patient files and the pathological specimens using Mikuz classification to analyze the relation between clinical and pathological findings. Results: A total of 289 patient charts from 14 centers were reviewed and 228 were included in this study. Twenty (8.8%) patients had grade 1 injury which refers to reversible injury. The clinical findings of these 20 patients were compared to 208 patients with higher grades of injury. As expected, there was statistically significant difference regarding duration of symptoms (p < 0.001); however, range was wide in both groups (as long as 96 h for grade 1 and as short as 7 h for higher grades). There was no statistically significant difference in any other variable including age (median 14 for both, p = 0.531), symptoms (pain: 19/20 vs. 189/202, p = 0.801; swelling: 13/19 vs. 168/197, p = 0.094), absence of blood flow in Doppler US (15/19 vs. 164/197, p = 0.635), or degree of torsion (median 720° for both, p = 0.172). Conclusion: Our study revealed necessity for better criteria to define viability of testis following TT. Histopathological injury appeared to be reversible even in some patients with more severe perioperative findings, late admission, or high degree of twisting. Our findings support the tendency for testicular fixation instead of orchiectomy as none of the clinical or perioperative findings could be attributed to high-grade injury. [ABSTRACT FROM AUTHOR]

This retrospective study was conducted in 27 patients with malignant transformation of mature cystic teratoma（MT-MCT）and 125 ovarian teratoma patients with torsion who underwent surgery in the First Affiliated Hospital of Wenzhou Medical University from 2008 to 2019. The incidence of MT-MCT in this study was 0.79%. The 3-year overall survival (OS) rate was 69.6 ± 9.6%. The 3-year progression-free survival (PFS) rate was 58.3 ± 9.6%. Kaplan–Meier survival analysis indicated that patients with squamous cell carcinoma (SCC) had significantly shorter OS compared with non-SCC patients. Older age (OR 1.076, 95% CI 1.041–1.111), higher platelet (PLT) level (OR 1.012, 95% CI 1.005–1.020) and lower neutrophil-to-lymphocyte ratio (NLR) level (OR 0.794, 95% CI 0.647–0.915) were independent predictors of MT-MCT. The area under the curve (AUC) for the combined use of age, PLT count and NLR was 0.921 (95% confidence interval 0.877–0.964; p < 0.001), with a sensitivity of 92.6% and a specificity of 80.8%.

Hypoplasia of the lung is an uncommon congenital abnormality of the respiratory system in contrast to pulmonary agenesis. Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is the congenital absence of the upper two-thirds of the vagina and uterus with normal secondary sexual characteristics, ovary and normal karyotype. We report a 31-year-old female patient who presented in 2022 with cough with expectoration, left-side chest pain and breathlessness for 4 years to tertiary hospital, Puducherry, India. She was evaluated for amenorrhoea and diagnosed as MRKH syndrome and the patient underwent right-side oophorectomy for right ovarian torsion with a tumour. Computed tomography pulmonary angiogram and fiberoptic endoscopy were suggestive of left lung hypoplasia and the patient was advised symptomatic treatment for lung hypoplasia and planned for vaginoplasty for which she refused.

Torsion of the Achilles tendon (AT) enhances tensile strength, but a high degree of torsion might also be a risk factor for Achilles tendinopathy, due to greater internal compression exerted during tensile loading. However, evidence supporting the grounds for this assumption is lacking. Hence, we aimed to investigate the impact of AT torsion type on intratendinous pressure. Eighteen human fresh frozen cadaveric legs were mounted in a testing rig and a miniature pressure catheter was placed through ultrasound‐guided insertion in the midportion region of the AT. Intratendinous pressure was measured during a simulated straight‐knee calf stretch and eccentric heel drop. The AT was then carefully dissected and classified into Type I (least), Type II (moderate), and Type III (extreme) torsion. Of the ATs examined, nine were found to have Type I torsion (50%), nine Type II (50%), and none Type III. It was found that the intratendinous pressure of the AT increased exponentially with ankle dorsiflexion during both exercises (p < 0.001) and that this increase was greater in ATs with Type II torsion than Type I torsion (p < 0.05). This study provides the first biomechanical data to support the hypothesis that in athletes with a high degree of torsion in the AT, the midportion area will experience more internal compression during exercise, for example, calf stretching and eccentric heel drops. Whether this phenomenon is also associated with an elevated risk for Achilles tendinopathy needs further prospective investigation. [ABSTRACT FROM AUTHOR]

Introduction: Torsion of a giant occipital encephalocele leading to necrosis is an extremely rare complication found in neonates with only two such cases reported in literature previously. Infection and ulceration of the necrosed skin may lead to meningitis or sepsis. We present here a neonate with giant occipital encephalocele showing progressive necrosis during the first day of his life. Case report: A new-born baby, delivered vaginally, with no antenatal imaging was found to have a huge mass in the occipital region, which was covered by normal pink-purplish skin. During the first day of his life, the sac started becoming ulcerated accompanied with a rapid colour change in the skin, gradually turning darker and then black. The pedicle of the encephalocele was twisted with progressive necrosis of the encephalocele. MRI showed a giant encephalocele with single vein draining into the torcula and dysplastic occipital lobe herniating into the defect. The neonate was taken up for urgent excision and repair of the encephalocele. The encephalocele was excised 'in-total' with 'figure-of-8' repair of the meninges. One year after the operation, she appears to be well-developed without any neurological problems. Conclusion: Necrosis may have resulted from arterial or venous compromise caused by torsion of the pedicle during delivery or after birth. The high pressure inside the sac associated with the thin skin of the encephalocele may be another predisposing factor. In view of the risk of meningitis and rupture, immediate surgery with repair with minimal blood loss is indicated. [ABSTRACT FROM AUTHOR]

The purpose of this report was to evaluate the usefulness of hyperdense whirl sign on unenhanced computed tomography (CT) for diagnosing gallbladder torsion. The CT scans of seven patients with gallbladder torsion were independently reviewed by two board-certified radiologists for locating the high-density core with twisting between the gallbladder neck and liver bed, termed hyperdense whirl sign. The sign was observed in six cases. The detection of a hyperdense whirl sign on unenhanced CT appears useful for diagnosing gallbladder torsion. [ABSTRACT FROM AUTHOR]

Key Clinical Message: Isolated utero‐ovarian torsion poses a challenge to diagnosing adnexal torsion, as it may not present with imaging findings. Clinicians with high suspicion for torsion but lack of evidence on ultrasonography should proceed to diagnostic laparoscopy. Adnexal torsion occurs when the ovary rotates around its supporting ligaments, the infundibulopelvic and utero‐ovarian (UO) ligaments, often causing disruption of blood supply. This pathology often presents with acute pelvic pain and is a gynecologic surgical emergency. Diagnosis is typically made with Doppler ultrasound, although dual blood supply to the ovary poses additional diagnostic challenges and sensitivity of this tool is debated. In this case study, we present a case of missed torsion due to isolated compromise of UO ligament. [ABSTRACT FROM AUTHOR]

Ovarian torsion (OT) is a gynaecological emergency and requires prompt recognition and treatment in order to prevent the loss of ovarian function. Patients who are undergoing fertility treatment are at an increased risk of developing OT. The diagnosis of OT in patients undergoing fertility treatment can be challenging as they often present with abdominal pain and other non-specific symptoms. We highlight the importance of early diagnosis of suspected torsion and performed a literature review on cases of bilateral OT to review its presentation, investigation, and subsequent management. Case report: A 32-year-old nulliparous woman who was undergoing controlled ovarian stimulation presented with lower abdominal pain and was initially managed as ovarian hyperstimulation syndrome (OHSS). Her pain did not subside following conservative management and she proceeded to have a laparoscopy which demonstrated synchronous bilateral ovarian torsion (SBOT), both ovaries were detorted. Eight months later, she was preparing for her frozen embryo transfer (FET) cycle, patient again presented with significant right sided abdominal pain and was found to have a recurrent torsion of the right ovary which was again detorted successfully. Clinicians should have a low-threshold to investigate and rule out OT in patients who present with lower abdominal pain, especially in those with additional risk factors for torsion. Patients with confirmed torsion can be successfully managed with detorsion of the ovaries. Further research is needed to determine the best management option for patients with recurrent torsion episodes. [ABSTRACT FROM AUTHOR]

Background & Objective: Adnexal torsion is a complete or incomplete twisting of the ovary, fallopian tubes, or ovarian cyst around its vascular axis, which can cause blood flow disruption. This disorder is rare but serious and accounts for about 3% of women's emergency surgeries. Early diagnosis of this disease and the necessary surgeries are very important to preserve fertility. The purpose of this study is to investigate the epidemiology, clinical symptoms, imaging and pathology of patients with torsion of the adnexa referred to the emergency rooms of Mahdiyeh and Shohadaye Tajrish hospitals. Materials & Methods: This study is a retrospective cross-sectional study. In the present study, 190 patients with torsion of the adnexa were examined in the period 2011–2021, in Mahdiyeh and Shohadaye Tajrish hospitals. Demographic, clinical and surgical information about patients was extracted from medical records. Data analysis was done using SPSS version 22 statistical software. Results: The average age of 190 patients was 29.2. Most of the ovarian torsion patients had a history of more than one previous delivery (57.9%) and also, an ovarian mass was observed in 157 patients, and the ovarian mass of 146 patients was larger than 5 cm. The rate of ovarian preservation in this study was 61%. Hemorrhagic cysts were the most common type of cyst in patients and were reported in 37 patients. Conclusion: It is necessary to identify effective diagnostic methods. Therefore, it may be useful to investigate more serum biomarkers for early detection of adnexal torsion and to reduce diagnostic errors. [ABSTRACT FROM AUTHOR]

Background and Objectives: The surgical treatment of proximal humeral shaft fractures usually considers application of either long straight plates or intramedullary nails. By being able to spare the rotator cuff and avoid the radial nerve distally, the implementation of helical plates might overcome the downsides of common fixation methods. The aims of the current study were (1) to explore the biomechanical competence of different plate designs and (2) to compare their performance versus the alternative treatment option of using intramedullary nails. Materials and Methods: Twenty-four artificial humeri were assigned to the following four groups for simulation of an unstable proximal humeral shaft fracture and instrumentation: Group 1 (Straight-PHILOS), Group 2 (MULTILOC-Nail), Group 3 (45°-Helical-PHILOS), and Group 4 (90°-Helical-PHILOS). All specimens underwent non-destructive, quasi-static biomechanical testing under loading in axial compression, torsion in internal/external rotation, and pure bending in four directions, accompanied by motion tracking. Results: Axial stiffness/displacement in Group 2 was significantly higher/smaller than in all other groups (p ≤ 0.010). Torsional displacement in Group 2 was significantly bigger than in all other groups (p ≤ 0.017). Significantly smaller coronal plane displacement was identified in Group 2 versus all other groups (p < 0.001) and in Group 4 versus Group 1 (p = 0.022). Significantly bigger sagittal plane displacement was detected in Group 4 versus all other groups (p ≤ 0.024) and in Group 1 versus Group 2 (p < 0.001). Conclusions: Intramedullary nails demonstrated higher axial stiffness and smaller axial interfragmentary movements compared with all investigated plate designs. However, they were associated with bigger torsional movements at the fracture site. Although 90°-helical plates revealed bigger interfragmentary movements in the sagittal plane, they demonstrated improved resistance against displacements in the coronal plane when compared with straight lateral plates. In addition, 45°-helical plates manifested similar biomechanical competence to straight plates and may be considered a valid alternative to the latter from a biomechanical standpoint.

Background: Early management for adnexal torsion increases likelihood of ovarian/tubal salvage. The Coronavirus disease of 2019 (COVID-19) pandemic poses delays from symptom-onset to intervention. The primary objective was to evaluate rates of ovarian salvage and tubal salvage following ovarian torsion and adnexal torsion during the COVID-19 pandemic in a pediatric and adolescent gynecology population. Methods: This was a retrospective quality improvement cohort study of pediatric and adolescent gynecology patients at a single children's hospital who underwent laparoscopy for suspected ovarian torsion/adnexal torsion between March 2020 to March 2021. Descriptive statistics and t-tests were utilized. Results: There were 50 suspected adnexal cases in 47 patients. All underwent laparoscopy, revealing 39 adnexal torsion occurrences in 36 patients and 1 patient with recurrent adnexal torsion three times. All underwent pre-operative COVID-19 testing. Mean age was 13.9 ± 2.6 years for adnexal torsion cohort. Menarche was achieved in 88% (n = 44) and 12% (n = 6) were pre-menarchal. The primary outcome was ovarian salvage and tubal salvage rates, which were 97.4% (n = 38) and 89.7% (n = 35), respectively. Secondary outcomes assessed factors contributing to the primary outcome or operative delays. The mean age of menarche was 11.2 years (salvaged) and 12.5 years (non-salvaged) (p = 0.04). There were no differences in mean pain duration or mean COVID-19 testing time between groups. Left, right and bilateral adnexal torsion occurred in 42% (n = 21), 32% (n = 16), and 4% (n = 2) respectively. The most common pathologies were paratubal cyst (n = 17, 34%) and benign ovarian cyst (n = 16, 32%). Conclusions: Ovarian salvage and tubal salvage rates were 97.4% and 89.7%, respectively during the time frame studied. These salvage rates during the study period are comparable to previous rates in a pre-COVID cohort at our institution. Institutional and departmental quality and safety initiatives likely contributed to this outcome. [ABSTRACT FROM AUTHOR]

Introduction: Miserable malalignment syndrome is a complex torsional lower limb deformity with limited consensus on surgical treatment. We present the outcome of de-rotation of the tibia alone using an external fixator. Methods: Fifteen patients (22 segments) were operated on between 2012 and 2020; 13 presented with anterior knee pain, and two presented with out-toeing. Gait analysis was done in nine patients, and CT scan rotational profile, including tibial tubercle–trochlear groove distance, femoral version, and tibial torsion, were calculated. Kujala knee pain score and visual analogue pain score (VAS) were recorded. All underwent infra-tubercular osteotomy of the tibia and midshaft osteotmy of the fibula and application of a hexapod circular frame to gradually internally rotate the tibia until the foot aligned with the patella. Results: There was no preoperative clinical or radiographic evidence for patellar instability, femoral anteversion 30° (21°–54°), and external tibial torsion 50° (37–70). The mean age at surgery was 21 years (12–37) with a mean follow-up of 20 months (9–83). All osteotomies healed, and the frames were removed at a mean of 111 days (80–168). The mean VAS score improved from 8(5–9) to 1(0–4) postoperatively (P < 0.001). The mean Kujala knee pain score increased from 53 (30–75) to 92 (54–100) postoperatively (P < 0.001). The mean preoperative foot progression angle (FPA) was 37° (20°–50°), with 13 postoperatively walking with neutral FPA. One patient walked with symmetrical + 10° and the other with − 5° FPA. All patients reported relief of knee pain and were satisfied with the alignment. Conclusion: Gradual correction of severe external tibia torsion with a hexapod external fixator and an infra-tubercle tibial osteotomy could provide an optimum method to eliminate knee pain and improve limb alignment in miserable malalignment syndrome.

A wandering spleen (WS) is a rare clinical entity characterized by a spleen located in the lower part of the abdomen or the pelvic cavity rather than the normal anatomical site. The complications of a wandering spleen include splenic torsion, splenic infarction, and adjacent visceral injury. We present a case of a male patient admitted to the emergency department with vomiting, nausea, and persistent lower abdominal pain. Computed tomography and ultrasound were performed and were used to diagnose a wandering spleen with torsion leading to splenic infarctions. Subsequently, laparoscopic surgery and pathology confirmed this diagnosis. Ultrasound and computed tomography scans play a significant role in diagnosing WS and its complications, allowing an emergency physician to establish treatment options for WS. [ABSTRACT FROM AUTHOR]

Recurrent torsion of otherwise normal adnexa (not involving adnexal cysts) has been reported in young girls and adolescents. Previous ovarian fixation techniques (oophoropexy), such as plication of the utero-ovarian ligament, appear to have limited efficacy in preventing recurrent torsion. A novel technique combining plication of the utero-ovarian ligament and suturing of the ovary to the round ligament has recently been described. In this study, we describe our short-term experience with the combined utero-ovarian and round ligament oophoropexy technique. Patients who underwent combined oophoropexy as a primary fixation technique or as a secondary fixation technique (ie, after failure of a previous fixation) due to recurrent torsion of otherwise normal adnexa between January 2020 and December 2022 were included in this retrospective cohort study. Follow-up to assess for further torsion events was conducted by telephone interview. Ten patients underwent combined utero-ovarian and round ligament oophoropexy during the study period. In all cases, at least 2 episodes of torsion of otherwise normal adnexa were surgically diagnosed before oophoropexy (range 2-4). The median patient age at the time of combined oophoropexy was 21.8 years (range 9.1-35.7 years); 3 were premenarchal, and 7 were postmenarchal. After a median follow-up of 19.1 months (range 3.0-29.3 months), only 1 case of recurrent torsion occurred. Combined utero-ovarian and round ligament oophoropexy is novel oophoropexy procedure that may reduce the risk of recurrent torsion. However, longer follow-up is needed to determine its efficacy.

Ovarian torsion can be seen in the otherwise-normal ovary and is a challenging issue in the emergency department. Definitive diagnosis is sometimes difficult to establish because of clinical symptoms similar to other abdominal diseases. We report a 22-year-old woman, nullipara, with acute lower right abdominal pain for 14 hours before coming to an emergency room. On examination, the abdomen was soft but tender over the right iliac fossa and rebound tenderness were present. Ultrasound radiological examination showed that the right ovary is grossly enlarged (volume-98.4cc) with hyperechoic central stoma. On colour, doppler twisted pedicel was noted. Mild collection is also seen in the pouch of Doglus. During laparoscopy, we found a blackish-red cystic mass of about 12 × 11 cm experiencing torsion. Then salpingo-oophorectomy was done. This is an interesting case of torsion in an otherwise-normal ovary with a huge hematosalpinx. [ABSTRACT FROM AUTHOR]

Introduction: Ovarian masses are not uncommon in pregnancy. The increased use of Ultrasonography (USG) in recent years has led to the detection of asymptomatic ovarian masses in pregnant women. Dermoid cysts are the most common type of ovarian germ cell tumour in pregnancy. Most of them are asymptomatic and are incidental findings. However, a few can present with complications such as torsion and rupture. The diagnosis and management of dermoid cysts in pregnancy present a clinical dilemma. Aim: To evaluate the management and outcomes of antenatal patients diagnosed with dermoid cysts. Materials and Methods: A retrospective observational study was conducted in the Department of Obstetrics and Gynaecology at Christian Medical College, Vellore, Tamil Nadu, India, from January 2015 to January 2022. The study included 37 patients, and data regarding the diagnosis of dermoid cysts, their radiological and clinical characteristics, management, and pregnancy outcomes were collected from the electronic database. Descriptive statistics were used for reporting demographic and clinical characteristics. Categorical variables were presented as numbers with percentages, while continuous variables were presented as mean with Standard Deviation (SD) or median with Interquartile Range (IQR). Results: The dermoid cysts ranged in size from 2.2 cm to 30 cm, with a mean size of 7.28±4.51 cm. A total of 35 (95%) of them were incidentally detected. USG was the imaging modality used for diagnosis and follow-up. Only 30% (11/37) of the patients required surgical intervention during the antenatal period. Torsion was the indication for emergency surgical intervention in 46% (5/11) of cases. Laparoscopy was the preferred approach for surgical intervention in 91% (10/11) of patients. The remaining 70% (26/37) of patients were managed conservatively with serial USG, and no adverse outcomes were reported. Among the patients who underwent caesarean section for obstetric indications, 35% (13/37) also underwent surgical intervention for the dermoid cyst (either cystectomy or oophorectomy) during the same procedure. Conclusion: Antenatal patients diagnosed with dermoid cysts during pregnancy can be managed conservatively with serial USG, with a plan for surgical intervention if needed. In cases where surgical intervention is required, it can be safely performed as a laparoscopic procedure. In case of complications such as torsion, laparoscopy can be performed during pregnancy with appropriate precautionary measures. [ABSTRACT FROM AUTHOR]

Introduction:  Since the onset of coronavirus disease 2019 (COVID-19), stay-at-home orders and fear caused by the pandemic have had a significant effect on the timing and outcomes of testicular torsion. However, the evidence was limited since the study results were inconsistent. This study aims to examine the hospitalization rates, timing, and outcomes of testicular torsion in children before and during the pandemic.Materials and Methods:  Using PubMed, Embase, and Google Scholar databases, we conducted a systematic search and meta-analysis of studies reporting the timing and outcomes of children admitted with testicular torsion before and during the COVID-19 pandemic. Subgroup analyses were conducted to explore possible sources of heterogeneity.Result:  The outcomes of 899 testicular torsion patients from eight studies were evaluated. Our study found an increased hospitalization rate for patients with testicular torsion (incidence rate ratio = 1.60, 95% confidence interval [CI]: 1.27-2.03; p = 0.001). Despite a significant increase in the duration of symptoms during the COVID-19 pandemic (weighted mean difference = 11.04, 95% CI: 2.75-19.33; p = 0.009), orchiectomy rates did not increase (odds ratio = 1.33, 95% CI: 0.85-2.10; p = 0.147).Conclusion:  During the COVID-19 pandemic, hospitalization rates for testicular torsion and the duration of symptoms among children increased significantly. Moreover, the rate of orchiectomy did not increase during the pandemic, indicating that pediatric emergency services have remained efficient and have prevented an increase in the number of orchiectomies performed despite pandemic-related closures and delays in transporting patients to medical care.

This study systematically examines pediatric adnexal torsion, proposing a diagnostic approach using machine learning techniques to distinguish it from acute appendicitis. Our retrospective analysis involved 41 female pediatric patients divided into two groups: 21 with adnexal torsion (group 1) and 20 with acute appendicitis (group 2). In group 1, the average age was 10 ± 2.6 years, while in group 2, it was 9.8 ± 21.9 years. Our analysis found no statistically significant age distinctions between these two groups. Despite acute lower abdominal pain being a common factor, group 1 displayed shorter pain duration (28.9 h vs. 46.8 h, p < 0.05), less vomiting (28% vs. 50%, p < 0.05), lower fever incidence (4.7% vs. 50%, p < 0.05), reduced leukocytosis (57% vs. 75%, p < 0.05), and CRP elevation (30% vs. 80%, p < 0.05) compared to group 2. Machine learning techniques, specifically support vector classifiers, were employed using clinical presentation, pain duration, white blood cell counts, and ultrasound findings as features. The classifier consistently demonstrated an average predictive accuracy of 87% to 97% in distinguishing adnexal torsion from appendicitis, as confirmed across various SVM models employing different kernels. Our findings emphasize the capacity of support vector machines (SVMs) and machine learning as a whole to augment diagnostic accuracy when distinguishing between adnexal torsion and acute appendicitis. Nevertheless, it is imperative to validate these results through more extensive investigations and explore alternative machine learning models for a comprehensive understanding of their diagnostic capabilities.

The assessment of ovarian perfusion after detorsion is crucial in the surgical management of patients with ovarian torsion. In current routine clinical practice, the surgical decision (preservation of the ovary versus oophorectomy) is based on the subjective impression of the surgeon. Intraoperative indocyanine green (ICG) angiography has been shown to sufficiently reflect tissue perfusion with a potential impact on the surgical procedure. Currently, there are only sparse data available on the utilization of ICG in the surgical treatment of ovarian torsion. Here, we describe the successful intraoperative use of ICG in a 17-year-old female patient with ovarian torsion who underwent ovary-preserving surgery. Further, a systematic literature review was performed. Based on the data available to date, the use of ICG in the surgical treatment of ovarian torsion is feasible and safe. The extent to which this might reduce the necessity for oophorectomy has to be evaluated in further investigations. [ABSTRACT FROM AUTHOR]

Epiploic appendagitis is a rare cause of acute lower abdominal pain. Epiploic appendices are fat-filled serosal outpouchings of the cecum and sigmoid colon. Primary epiploic appendagitis (PEA) is characterized by epiploic inflammation caused by torsion of the appendage leading to ischemia or thrombosis of the appendage draining vein. Secondary epiploic appendagitis occurs in association with other inflammatory conditions of the abdomen or pelvis, most commonly diverticulitis. PEA is an important clinical mimicker of more severe causes of acute abdominal pain, such as diverticulitis, appendicitis, or gynaecological causes. The ease of access to computed tomography (CT), the diagnostic test of choice, has resulted in increased recognition of PEA. The classic CT findings of PEA are an ovoid mass measuring between 1.5 and 3.5 cm surrounded by a hyperattenuating/hyperdense ring with a centrally located hyperdense area. It is important to diagnose PEA as it is self-limiting and the correct diagnosis can prevent unnecessary hospital admission, antibiotic use, or even surgical intervention. We present a case of a 65-year-old male with a history of diverticulitis, presenting with left lower quadrant abdominal pain who was diagnosed with PEA based on CT and successfully managed with conservative treatment.

Purpose: To report the rate of ocular torsion in children with horizontal strabismus or orthophoria. Methods: A retrospective study design was used. Nineteen children were included in the study, including seven girls, aged 4–16 years. All patients were examined for strabismus and 12 were scheduled for surgical intervention. All participants had digital fundus photos (DRSplus, Padova, Italy) of both eyes at presentation, and 5 of 12 also had fundus photos following the strabismus operation. Patient files were reviewed for age, demographic data, type of strabismus, clinical symptoms and signs, orthoptic exams, subjective and objective reports of torsion, inferior oblique overaction, and V pattern. Fundus photos were analyzed for torsion by ImageJ software [ImageJ 1.54f, National Institute of Health, USA]. The disc-foveal angle was calculated for ocular torsion. Disc-foveal angle was defined as the angle formed between a line passing through the center of the optic disc to the fovea and another horizontal line passing through the center of the optic disc, using fundus photographs. Results: Of the 19 children, 18 had horizontal strabismus: 9 with exotropia and 9 with esotropia. One child was orthophoric with torsional strabismus. Inferior oblique overaction was detected in all but 3 children, while V pattern was documented in 10. Visual acuity was reduced (under 6/12) in four eyes of four children. None were symptomatic for ocular torsion. Although extorsion was documented clinically in 3 of 19 children, it was measurable on fundus photos in all patients before surgery with a mean of 8.7 ± 8.5 degrees and 8.5 ± 9.7 degrees in the right and left eyes, respectively. The mean extorsion in both eyes was 19.7 ± 10.1 degrees and improved to a mean of 15.3 ± 7.9 degrees in the children who were operated on and had documented postoperative fundus photographs. Conclusions: Extorsion was detected on fundus photos at a significantly higher rate than in clinical examination. Notably, inferior oblique overaction was mainly associated with torsion. This study demonstrated that torsion is underdiagnosed in clinical examinations, as the children are often asymptomatic, but fundus photos which are easily obtained can improve its detection.

Polycystic ovary syndrome (PCOS) constitutes the most prevalent endocrine disorder in women of reproductive age worldwide. Given the increased risk of ovarian torsion in the presence of large ovarian cysts, polycystic ovarian syndrome could be regarded as one of the most significant risk factors for ovarian and/or adnexal torsion in cases of significantly enlarged ovaries. The aim of the present review is to investigate, for the first time, the association between polycystic ovarian syndrome and ovarian torsion. We performed a review of the literature using the MEDLINE and LIVIVO databases in order to find relevant studies. By using the search terms "polycystic ovarian syndrome" and "ovarian torsion", we were able to identify 14 studies published between 1995 and 2019. The present work constitutes the most up-to-date, comprehensive literature review focusing on the risk of ovarian/adnexal torsion in patients with polycystic ovaries. Ovarian/adnexal torsion seems to be a feared complication in patients with polycystic ovary syndrome. Acute lower abdominal pain in patients with known polycystic ovaries represents the most common symptom, while diagnostic assessment almost always incorporates transvaginal ultrasound and computer tomography or magnetic resonance tomography scans. In case of suspected torsion, emergency laparoscopy with ovarian or adnexal detorsion seems to be the standard therapeutic approach with a view to restitute the interrupted blood supply. In cases of repeated ovarian/adnexal torsions, ovariopexy or ovariectomy/adnexectomy had to be discussed with the patient in the context of risk recurrence minimization. [ABSTRACT FROM AUTHOR]

OBJECTIVE: In this study, we aimed to investigate the effect of sildenafil, acting as an anti-oxidant on the ischemic rat ovarian torsion model by pointing out ovarian reserve via AMH levels which is the best marker for oocyte pool. STUDY DESIGN: This study is an experimental animal study conducted according to the principles of the Declaration of Helsinki. Twenty-seven rats were assigned into three groups, each consisting of nine individuals. Group 1: Sham operation (laparotomy only) was performed. Group 2: The torsion group had bilateral torsion and detorsion of the ovaries. Group 3: In Sildenafil and torsion group the rats received 0.7 mg/kg sildenafil (Viagra, Pfizer, New York, ABD) intraperitoneally one hour before torsion and detorsion operation. One month after the initial operation, blood was drawn via the intra-cardiac route, and serum antimullerian hormone (AMH) concentrations were studied. RESULTS: The mean weights of the rats were similar 224 g, 229 g, and 222 g for groups 1, 2, and 3 respectively. Only one rat from Group 2(T/D) died during the experiment leaving eight rats for analysis. The mean value for AMH was 24.9227±12.19124 ng/ml and the mean value for weight was 226.22±19.200. The differences in AMH groups were not statistically significant (p=0.873) CONCLUSIONS: As a result, as is shown in our study, the ovarian reserve may not be influenced by ischemia developed by ovarian torsion or any influences could not change AMH levels. Sildenafil which was given to the rats before detorsion to protect against reperfusion ischemia was found to be ineffective on ovary reserve according to AMH assessment. [ABSTRACT FROM AUTHOR]
