A Case Report of Uterine Torsion in a Postmenopausal Female with a Large Leiomyoma.

This case report discusses a diagnosis of uterine torsion in an 84-year-old woman who presented with five days of right lower quadrant abdominal pain, nausea, vomiting, constipation, and poor intake. Computed tomography (CT) imaging demonstrated a whorled configuration at the junction of the cervix and lower uterine segment, with the left gonadal vein crossing midline, and two previously known right leiomyomas now appearing on the left. These findings were consistent with the diagnosis of uterine torsion. She then underwent an urgent exploratory laparotomy, and the uterus was found to be dextroverted 270 degrees, with dark mottled purple tissue and engorged vessels. A supracervical hysterectomy and bilateral salpingo-oopherectomy were performed. Final pathology demonstrated extensive necrosis. This case reviews the classic presentation and imaging findings for the rare diagnosis of uterine torsion and options for management of both non-gravid and gravid patients.

An acute gastric volvulus in a child with congenital left diaphragmatic hernia: a case report.

BACKGROUND: Acute complete gastric volvulus is a rare and life-threatening disease, which is prone to gastric wall ischemia, perforation, and necrosis. If it is not treated by surgery in time, the mortality rate can range from 30 to 50%. Clinical presentations of acute gastric volvulus are atypical and often mimic other abdominal conditions such as gastritis, gastroesophageal reflux, gastric dilation, and pancreatitis. Imaging studies are crucial for diagnosis, with barium meal fluoroscopy being the primary modality for diagnosing gastric volvulus. Cases of acute gastric volvulus diagnosed by ultrasound are rarely reported. CASE PRESENTATION: We reported a rare case of acute gastric volvulus in a 4-year-old Chinese girl who presented with vomiting and abdominal pain. Ultrasound examination revealed the "whirlpool sign" in the cardia region, raising suspicion of gastric volvulus. Diagnosis was confirmed by X-ray barium meal fluoroscopy, which indicated left-sided diaphragmatic hernia and obstruction at the cardia region. Surgical intervention confirmed our suspicion of acute complete gastric volvulus combined with diaphragmatic hernia. CONCLUSION: In this case, we reported an instance of acute complete gastric volvulus. Ultrasound revealed a "whirlpool sign" in the cardia, which is likely to be a key sign for the diagnosis of complete gastric volvulus.

Point-of-care ultrasonography for the diagnosis and manual detorsion of testicular torsion.

Testicular torsion is a urological emergency caused by the loss of testicular tissue due to ischemic damage. Rapid diagnosis and urgent treatment play a crucial role in the management of testicular torsion. Manual detorsion can be performed at the bedside, thereby reducing the duration of ischemia. Recent studies have reported the use of point-of-care ultrasonography for diagnosing testicular torsion; however, no review article has focused on the ultrasonographic findings pertaining to manual detorsion. This review describes the diagnosis of testicular torsion and the ultrasonographic indications for manual detorsion. Spermatic cord twisting or the whirlpool sign, absence of or decreased blood flow within the affected testis, abnormal testicular axis, abnormal echogenicity, and enlargement of the affected testis and epididymis due to ischemia are the sonographic findings associated with testicular torsion. The following findings are considered indications for manual detorsion: direction of testicular torsion, i.e., inner or outer direction (ultrasonographic accuracy of 70%), and the degree of spermatic cord twist. The following sonographic findings are used to determine whether the treatment was successful: presence of the whirlpool sign and the degree and extent of perfusion of the affected testis. Misdiagnosis of the direction of manual detorsion, a high degree of spermatic cord twisting and insufficient detorsion, testicular compartment syndrome, and testicular necrosis were found to result in treatment failure. The success of manual detorsion is determined based on the symptoms and sonographic findings. Subsequent surgical exploration is recommended in all cases, regardless of the success of manual detorsion.

Intrauterine Volvulus: A Case Report.

Intrauterine volvulus is an extremely rare disorder. Its diagnosis is difficult to make antenatally, unless typical pictures are obtained. Owing to its high morbidity and mortality, intensive monitoring of the fetal condition is mandatory. Here, we report a patient, gravida 4, para 1 (G4P1), who had suffered from preterm labor and diminishing fetal movement and was brought to the emergency unit after her 35th week of pregnancy. Ultrasonography was performed to reveal a fetus with a markedly distended bowel (18 mm in width). Intestinal obstruction related to intrauterine volvulus was highly suspected. The fetus was delivered via Cesarean section because of its deteriorated abdominal condition. Urgent exploratory laparotomy was done by a pediatric surgeon to relieve the bowel obstruction on the second day after birth, on the account of poor improvement of the newborn. The newborn did well after segmental resection and was subsequently followed up at the pediatric outpatient clinic. In conclusion, early detection, intensive monitoring, prompt delivery, and urgent surgical intervention are the key to save the fetal life and neonatal health.

The genome sequence of the Whirlpool Ramshorn snail, Anisus vortex (Linnaeus, 1758).

We present a genome assembly from an individual Anisus vortex (the Whirlpool Ramshorn snail; Mollusca; Gastropoda; Hygrophila; Lymnaeoidea; Planorbidae). The genome sequence is 869.5 megabases in span. Most of the assembly is scaffolded into 18 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 13.57 kilobases in length.

Delayed Presentation of Malrotation: Case Series and Literature Review.

Background: Intestinal malrotation is a congenital anomaly resulting from abnormal or incomplete rotation and fixation of the midgut during embryogenesis. It commonly presents in the neonatal period (75%) with sudden onset bilious vomiting and rarely beyond infancy (<10%). Aim: The aim of the study was to highlight the clinical features, radiological findings, and treatment outcomes of patients with malrotation presenting beyond infancy. Materials and Methods: Eleven consecutive cases of delayed presentation of malrotation presented over a period of 5 years (2017-2021). Data were analyzed retrospectively. Results: Out of the 11 patients, four were female and seven were male. The age of patients ranged from 14 months to 18 years. Patients beyond infancy present usually with diffuse pain abdomen compared to neonates which present with sudden onset bilious vomiting and therefore difficult to diagnose. Five patients had associated abnormalities such as intussusception or nutcracker syndrome or mesenteric cyst or jejunal stricture or mesenteric lymphadenopathy along with malrotation. Patients underwent ultrasonography, upper gastrointestinal contrast study, and contrast-enhanced computed tomography abdomen to confirm the diagnosis. All patients underwent the Ladd procedure with four requiring resection anastomosis and one requiring excision of the mesenteric cyst. Eight out of eleven patients had favorable outcomes, two develop adhesive intestinal obstruction and required re-exploration, and one had persistent complaints of hematochezia. Conclusion: Malrotation beyond infancy is a rare diagnosis. Malrotation in older children is usually not suspected because of the wide range of symptoms. A high index of suspicion on ultrasound or computed tomography is required to demonstrate the reversal of superior mesenteric artery and superior mesenteric vein position and related conditions. Early intervention and treatment can prevent catastrophic events such as intestinal volvulus and intestinal ischemia in these patients.

Ovarian torsion due to ovarian hyperstimulation syndrome diagnosed by sonographic whirlpool sign in the first trimester of pregnancy: A case report.

Ovarian torsion during pregnancy is a rare condition that needs prompt diagnosis and detorsion in order to preserve ovarian function. Diagnosing ovarian torsion is a difficult procedure especially in pregnant cases since radiation exposure should be avoided. Detecting the whirlpool sign by ultrasonography is a highly useful technique as it is noninvasive, less time-consuming, and radiation-free. Here is a case of ovarian torsion due to ovarian hyperstimulation syndrome diagnosed solely by sonographic features and in which laparoscopic detorsion was promptly performed. A 26-year-old woman in her sixth week of pregnancy visited a tertiary hospital with sudden onset lower abdomen pain. Transvaginal ultrasound detected an 8 cm left ovary and a whirlpool sign between the uterus and left ovary. Ovarian torsion was suspected and laparoscopic surgery was performed. Intraoperatively, an enlarged left ovary was twisted at 540° involving the left fallopian tube. After detorsion, bilateral ovaries were preserved and the postoperative course was uneventful. Ovarian torsion was suspected solely by ultrasonographic features which led to surgical detorsion quickly, resulting in the preservation of bilateral ovaries. Detecting the whirlpool sign when ovarian torsion is suspected is useful, especially in pregnant women.

Step-by-step instructions for detecting whirlpool sign in adnexal torsion.

Objective: Adnexal torsion is a common gynecological emergency whose prompt diagnosis is essential because a delay may lead to ovarian dysfunction. Although the whirlpool sign is reliable for diagnosing ovarian cyst torsion, technical difficulties hinder its use by sonographers. Here we developed a systematic approach to visualizing this sign by focusing on the fact that torsion arises from the space between the uterus and the pelvic wall. One must determine the origin of the torsion via transverse imaging of the uterus and follow the twisted ligaments to the ovarian cyst. Patients and Methods: Two women aged 56 (Case 1) and 28 years (Case 2) visited our hospital with lower abdominal pain. Transvaginal ultrasonography showed a 7-cm right ovarian cyst in Case 1 and a 5-cm cyst in the Douglas pouch in Case 2; normal bilateral ovaries and the whirlpool sign were detected in both cases. Under laparoscopic guidance in Cases 1 and 2, an ovarian cyst and a paraovarian cyst were confirmed and removed. Results: Our step-by-step method allowed us to identify the whirlpool sign and confirm adnexal torsion, leading to prompt surgery in both cases. Conclusion: Using a systematic procedure helps less experienced practitioners detect the whirlpool sign.

Fetal malrotation with midgut volvulus: Prenatal diagnosis and planning.

Introduction: Malrotation of the intestinal tract is a congenital malformation commonly found either incidentally or after affected individuals develop signs and symptoms of intestinal obstruction. Malrotation is prone to midgut volvulus that can cause intestinal obstruction and lead to ischemia and necrosis requiring emergent surgical intervention. Rare instances of in utero midgut volvulus have been reported in the literature and carry a high mortality given the difficulty in establishing a diagnosis prior to development of signs of intestinal ischemia and necrosis. Advancements in imaging have made it possible to diagnose in utero malrotation earlier, raising the question of optimal timing of delivery, especially in cases of prenatally diagnosed midgut volvulus. In these cases, the risks of premature birth must be weighed against the risks of fetal intestinal ischemia and potential fetal demise. Case presentation: This case report details an interesting presentation of intestinal malrotation with suspected midgut volvulus found on prenatal imaging at 33 weeks and 4 days' gestation. This prompted delivery of the infant at 34 weeks and 2 days' gestation with urgent operative management, within 3 hours of life, after diagnosis was confirmed postnatally. Intraoperatively, the infant was confirmed to have midgut volvulus without bowel ischemia, the intestines were reduced, and a Ladd procedure was performed without incident. The infant recovered postoperatively without complication, tolerated advancement to full volume feeds and was discharged on day of life 18. Conclusion: Successful management of fetal malrotation with midgut volvulus may be accomplished by early access to a multi-disciplinary team of professionals, prompt postnatal confirmation of diagnosis, and urgent correction to minimize the risk of complications.

Relationship Between The "Sexual Abuse Whirlpool" and Gender, Type of Abuse, Victim-Perpetrator Relationship, Disclosure, Psychological Reactions, and Revictimization of Sexual Abuse Victims.

According to the Sexual Abuse Whirlpool framework, when a vulnerable child is noticed by a perpetrator, the state of vulnerability he/she is in will reach a severe level. The SAW asserts that the method applied by the perpetrator has a multiplier effect on the child's vulnerability and accelerates the process resulting in abuse. The study aimed to investigate the relationship between the SAW and gender, type of abuse, victim-perpetrator relationship, disclosure, psychological complaints and reactions (PCRs), and revictimization of sexual abuse victims. A mixed research method was used: First, the vulnerabilities of the victims were extracted from the forensic interview forms with a qualitative method (n = 199). Then collected data were tabulated and digitized quantitatively. Victims who were exposed to penetrative abuses, who did not disclose, had serious PCRs, and who were re-victimized had high scores of the SAW. Whirlpool would decrease in places where there is a quality parent-child relationship.

Atypical Presentation of a Giant Hemorrhagic Ovarian Cyst.

Hemorrhagic ovarian cysts (HOCs) are frequently seen in reproductive age women, developing in the luteal phase of ovulatory cycles. Giant HOCs are rare, as bleeding inside a closed space causes acute pain leading to early diagnosis. Anovulation or oligoovulation is a defining feature of polycystic ovarian syndrome (PCOS), and hence, functional cysts are uncommon in PCOS patients. This report describes a young girl with PCOS and amenorrhea, presenting with a giant hemorrhagic ovarian cyst. Most hemorrhagic cysts undergo spontaneous resolution with follow-up. Our patient presented as a surgical emergency following torsion and rupture with hemoperitoneum. Torsion causes an obstruction in the blood flow leading to infarction and loss of ovarian viability. Early diagnosis and detorsion may help to preserve ovarian function.

Prenatal diagnosis of fetal midgut volvulus: a case report.

BACKGROUND: Fetal midgut volvulus is an uncommon yet potentially life-threatening condition. Prenatal diagnosis may pose a challenge, due to the paucity of specific signs and symptoms. Timely prenatal diagnosis of this condition is imperative to prevent fetal mortality and morbidity. CASE PRESENTATION: We present a rare case report of fetal midgut volvulus, malrotation, and intestinal obstruction at 32 weeks of gestation in a 31-year-old multigravida Indian patient who presented with decreased fetal movements. Fetal ultrasound revealed midgut volvulus with proximal bowel obstruction and polyhydramnios. The patient underwent emergency surgery, which revealed intestinal malrotation and confirmed the diagnosis of midgut volvulus. Untwisting of the volvulus was done followed by Ladd's procedure. Follow-up postoperative ultrasound was unremarkable. CONCLUSIONS: Delay in the diagnosis of fetal midgut volvulus leads to poor fetal and maternal outcomes. Hence, it is vital for radiologists, sonologists, and obstetricians to be aware of this condition while performing fetal sonography. Prompt diagnosis and surgical intervention are vital to reduce the morbidity and mortality associated with this condition.

The diagnostic value of ultrasound in pediatric testicular torsion with preserved flow.

Background: Testicular torsion is the reduction of blood flow to the testis after spermatic cord torsion. For patients, the diagnosis of testicular torsion is controversial and complicated by the fact that ultrasound blood flow signals are not significantly reduced in comparison to the unaffected, healthy, testis, despite persistent symptoms on the affected side. Our study aims to investigate the diagnostic characteristics of high-resolution ultrasonography (US) in pediatric testicular torsion with the preserved flow to increase diagnostic accuracy. Methods: Seven pediatric patients aged 49 days to 15 years old, with the preserved blood flow, but surgically diagnosed as testicular torsion, from October 2017 to August 2019, were retrospectively included in the study. The imaging manifestations of high-frequency ultrasonography were evaluated. Results: All cases had preserved testicular blood flow, but the surgical findings showed various degrees of twist, from 90 to 540 degrees. Preoperative ultrasound showed spermatic cord distortion in all cases, and testicular long axis tilting in four cases (4/7 = 57.1%). Conclusion: In some testicular torsion cases, Color Doppler may show normal or increased blood flow signals in the testis. We should further observe the morphology and position of the testes and epididymides, the echo of the testicular parenchyma, and, especially evaluate the "whirlpool sign" in the spermatic cord, to avoid missing testicular torsion with blood flow signals.

Reversed intestinal malrotation presenting as bowel obstruction in pregnancy: Case report and literature review.

Introduction: Midgut malrotation is a congenital condition caused by insufficient normal intestinal rotation following physiologic gut herniation. Reverse rotation of the midgut is the rarest kind of intestinal malrotation, accounting for about 2%-4% of all cases. Case presentation: We report a case of a 26-year-old South Asian gravida with a previous history of quadruple miscarriage and ovulation induction, presented as intestinal obstruction due to reverse malrotation. An MRI of the abdomen indicated that the mesentery had become twisted around the SMA, resulting in a "whirlpool" pattern. Open exploration was done to accomplish lysis of restricting bands with appendectomy. Conclusion: Intestinal obstruction in pregnancy is uncommon, but when unrecognized in a timely fashion, it is associated with significant maternal and fetal mortality. A simple release of constricting bands without antimesenteric transposition seems to be the safest option in this situation.

Virulent Pseudomonas aeruginosa pneumonia in an immunocompetent adult associated with a home whirlpool bath: A case report.

We present a case of life-threatening pneumonia caused by Pseudomonas aeruginosa (P. aeruginosa) in a healthy 67-year-old man. Rapid disseminated infection resulted in the right hemorrhagic pneumonia and bacteremia. Antimicrobial therapy had limited effects, radical pneumonectomy eventually resolved the prolonged infection. Concurrently, we explored the environmental factors responsible for fulminant P. aeruginosa infection. Multi-locus sequence typing demonstrated that P. aeruginosa isolated from the patient was identical to that collected from home whirlpool bath by the common virulent factor gene. Massive inhalation of contaminated aerosol and pathogen virulence may have synergistically contributed to the severity in this case.

Case Report: Splenic Ischemia Induced by Volvulus of Ileum.

A 31-year-old female patient was admitted to the emergency department with signs and symptoms of acute abdomen. Urgent CT scan was performed and small bowel volvulus, with whirlpool sign, was noted and torsion of the spleen was also involved too.

Point-of-Care Ultrasonography as an Extension of the Physical Examination for Abdominal Pain in the Emergency Department: The Diagnosis of Small-Bowel Volvulus as a Rare Complication after Changing the Feeding Jejunostomy Tube.

Point-of-care ultrasonography (POCUS) has become the most popular modality of testing for physicians in recent years and is used for improving the quality of care and increasing patient safety. However, POCUS is not always acceptable to all physicians. To address the benefits and importance of POCUS, numerous studies have examined the use of POCUS in clinical practice and even medical education. This article aims to highlight the effects of POCUS as an extension of the physical examination, and we present a case to address the reasons it should be performed. For a man experiencing abdominal pain immediately after his feeding jejunostomy tube was changed, there was high suspicion of small-bowel volvulus after a "whirlpool sign" was observed during the POCUS, whereby mesenteric vessels presented in a whirling or spiral shape. This impression was subsequently confirmed by computed tomography. Small-bowel volvulus is a rare complication of changing a feeding jejunostomy tube. The images submitted here add to the sparse evidence from the literature on the use of POCUS as an extension of the physical examination for evaluating abdominal pain. POCUS can be used after taking the patient's history and conducting a physical examination. The observation of a whirlpool sign may indicate the presence of a volvulus that is life-threatening.
