Wandering spleen combined with pedicle torsion and splenic infarction: a rare case report and literature review.

Wandering spleen (WS) concurrent with splenic pedicle torsion and infarction has been described rarely. We reported our experience in diagnosing and treating such a condition in a 16-year-old girl with acute abdominal pain. A plain CT scan showed the wandering of the spleen from the left upper quadrant. Contrast-enhanced CT indicated dilatation and distortion in the splenic vein, a counterclockwise "whirl sign" in the splenic pedicle, pancreatic tail torsion, and splenic infarction. The patient was diagnosed with WS combined with splenic pedicle torsion and splenic infarction and underwent splenectomy for treatment. She showed a satisfactory outcome during the follow-up. To enhance our understanding of it, we performed a comprehensive literature research to summarize the clinical manifestations, treatment options, and outcomes among adolescent patients.

Extralobar pulmonary sequestration in children with abdominal pain: Four case reports.

BACKGROUND: Extralobar pulmonary sequestration (ELS) with torsion is extremely rare, consequently, the diagnosis of ELS with torsion in children presents a challenge for clinicians. Herein, we report four cases of ELS with torsion that presented with abdominal pain, and further review the relevant literature to summarize the clinical features. CASE SUMMARY: Four children presented to our department with abdominal pain. All underwent chest computed tomography, which revealed an intrathoracic soft tissue mass with pleural effusion. All four children underwent thoracoscopic resection of the identified pulmonary sequestration, and the vascular pedicle was clipped and excised. None of the patients experienced any postoperative complications. CONCLUSION: Clinicians should consider the possibility of ELS with torsion in children presenting with abdominal pain as the chief complaint.

Measurement of maize stalk shear moduli.

Maize is the most grown feed crop in the United States. Due to wind storms and other factors, 5% of maize falls over annually. The longitudinal shear modulus of maize stalk tissues is currently unreported and may have a significant influence on stalk failure. To better understand the causes of this phenomenon, maize stalk material properties need to be measured so that they can be used as material constants in computational models that provide detailed analysis of maize stalk failure. This study reports longitudinal shear modulus of maize stalk tissue through repeated torsion testing of dry and fully mature maize stalks. Measurements were focused on the two tissues found in maize stalks: the hard outer rind and the soft inner pith. Uncertainty analysis and comparison of multiple methodologies indicated that all measurements are subject to low error and bias. The results of this study will allow researchers to better understand maize stalk failure modes through computational modeling. This will allow researchers to prevent annual maize loss through later studies. This study also provides a methodology that could be used or adapted in the measurement of tissues from other plants such as sorghum, sugarcane, etc.

Acute Abdomen Accompanied by Torsion of a Segment of the Jejunum Due to Meckel's Diverticulum: A Rare and Interesting Case.

Meckel's diverticulum is a common congenital anomaly of the gastrointestinal tract and is often asymptomatic. This case report details the diagnosis and treatment of small bowel obstruction particularly in a segment of the jejunum in a 41-year-old woman due to Meckel's diverticulum. The patient presented with diffuse abdominal pain and bloating. Imaging and clinical evaluation revealed signs of ileus, leading to an exploratory laparotomy. Intraoperative findings included a mass consistent with Meckel's diverticulum causing adhesion and torsion of the jejunum. The surgical intervention involved adhesiolysis and segmental enterectomy with side-to-side anastomosis. Histopathological analysis confirmed Meckel's diverticulum with ectopic gastric mucosa. The patient had an uneventful postoperative recovery and was discharged on the seventh postoperative day.

Long time follow-up for patients with testicular torsion: new findings.

BACKGROUND: Testicular torsion is the major urologic emergency. If not treated promptly, this condition can result in testicular necrosis or long-term functional impairment. At present, there are few paper about long time follow-up of these patients. The primary objective of our study is to report the long-term clinical-instrumental data (mean follow-up 12 years) of patients treated for testicular torsion. METHODS: We considered patients treated for testicular torsion during the period between 1997 and 2017. Inclusion and exclusion criteria were created. Patients were contacted by phone between December 2021 and January 2022. Each patient underwent clinical and ultrasonographic evaluation, and in addition, some subjects were offered additional tests (hormonal assays and semen analysis). RESULTS: During the study period, 22 patients were treated for testicular torsion. From the ultrasonographic study, it was found that the volume of the affected testis is reduced and it is associated with microcalcifications and heterogeneous echogenicity. Morphovolumetric recovery seems to be more related to age of onset than to the degree of torsion. CONCLUSIONS: Based on our results we can state that affected testes, if preserved, grow less and have altered ultrasonographic morphology. Clinically, the age of onset of torsion seems more important than the degree of torsion.

Genitourinary Ultrasound.

Renal and genitourinary (GU) complaints are common reasons for presentation to the emergency department (ED). This article reviews the approach to renal, bladder, and testicular point-of-care ultrasound (POCUS) with specific discussions of commonly encountered ED pathology. It presents algorithms highlighting the clinical integration of renal and GU POCUS into the evaluation and management of these patients.

Twisted Fate: A Case Study of Postmenopausal Ovarian Torsion With Gangrene.

An emergency medical evaluation for ovarian torsion should be conducted on any female who complains of stomach pain. More women in the reproductive age range experience ovarian torsion. Ovarian torsion presenting postmenopausal is an uncommon occurrence. Torsion of ovaries can occur alone or with torsion of the fallopian tubes. Pain is the main presenting complaint, which may be accompanied by swelling, nausea, etc. In this instance, we have a 52-year-old woman who complained of lower abdominal pain on the right side. A transvaginal ultrasonography (USG) was done, and torsion of the right ovary was found. On further exploration, it was found to be gangrenous.

Primary omental torsion with clinical masquerading as acute appendicitis and radiological key for diagnosis.

Omental torsion is a medical condition characterized by the twisting of the omentum along its longitudinal axis, which leads to compromised blood flow. This condition is rarely diagnosed before surgery and can present symptoms similar to other causes of acute surgical abdomen. This report details a case of primary omental torsion initially suspected to be acute appendicitis. The patient was admitted to the hospital with symptoms of lower right quadrant abdominal pain and mild fever. Computed tomography imaging revealed a twisted mass of fatty tissue with surrounding fat stranding changes, but no signs of appendicitis were found, indicating omental torsion. The patient underwent surgery to remove the twisted and necrotic omentum, leading to an improvement in symptoms. This case highlights the challenges in diagnosis and the crucial role of computed tomography imaging in managing this rare condition.

Ovarian Torsion Leading to Necrosis: A Case Report of Acute Abdominal Pain in a 25-Year-Old Female.

Ovarian torsion is a critical gynecological emergency that presents with sudden-onset abdominal pain and requires immediate intervention to prevent irreversible ovarian damage. This case report describes a 25-year-old female who presented with acute right lower quadrant pain, which had escalated to excruciating levels over the past 45 minutes, accompanied by persistent nausea and vomiting. She had no fever, vaginal bleeding, or dysuria, and her urine pregnancy test was negative. A physical examination revealed significant tenderness and guarding in the right lower abdomen, with no evidence of organomegaly or abnormal pelvic findings. Imaging studies, including ultrasound, confirmed the diagnosis of a complete ovarian torsion with associated necrosis. The patient underwent successful laparoscopic surgery, which involved the removal of the necrotic ovary and affected fallopian tube. Postoperative recovery was uneventful, and the patient fully recovered within a week. This case underscores the importance of early diagnosis and surgical intervention in managing ovarian torsion to preserve ovarian function and prevent complications.

Utility of Ultrasonography for Diagnosing an Ectopic Testis With Torsion: A Case Report.

Since ectopic twisted testes are a rare condition, correctly and opportunely diagnosing them preoperatively is difficult and can result in testicular necrosis. We report a clinical case of a twisted ectopic testis that was diagnosed preoperatively by ultrasonography, and the testis could be rescued. A generally healthy 13-year-old boy was referred to our Urology Department after experiencing a painless swelling in the left inguinal region two weeks before, and mild exercise-induced pain in the same area one week before the referral. The mild pain persisted without worsening. On examination, a mildly tender swelling was present in the left inguinal region. The left half of the scrotum was empty; however, the right testis was normal in size and position. Ultrasonography revealed that the left spermatic cord was present within the inguinal canal and was directed superficially, with spiral twisting. The left testis was located above the inguinal canal, with normal echogenicity, but was smaller than the right normal testis (right testis, 41 × 28 × 16 mm; left testis, 18 × 18 × 8 mm). Power Doppler ultrasound showed normal blood flow in the left testis. Consequently, we diagnosed an ectopic testis with torsion. Intraoperative examinations confirmed the presence of the testis in the left superficial inguinal pouch. Although the testis had twisted five and a half turns (1980°) clockwise at the level of the superficial inguinal pouch, ischemia was not evident. Orchidopexy of both testes was performed, and the left testicular size was maintained after surgery. If swelling is present in the inguinal region and no testis is found in the scrotum, an ectopic testis should be considered in the differential diagnosis. Preoperatively diagnosing an ectopic, twisted testis by ultrasonography alone is difficult. However, we used ultrasonography effectively to diagnose the ectopic testis preoperatively by tracking the spermatic cord and confirming the torsion of the testis.
