Meckel's diverticula are one of the most common gastrointestinal anomalies, yet mesodiverticular bands are rare. The treatment of these bands commonly requires surgery. A healthy patient in his 20s presented to the emergency department with a 1 day history of acute onset abdominal pain. Computed tomography imaging was consistent with volvulus of the large intestine. In the operating room, the patient was noted to have a band between the ileal mesentery and tip of a Meckel's diverticulum, consistent with a mesodivertiular band, through which cecum had volvulized. The patient underwent resection. The patient recovered without major complications. Mesodiverticular bands are rare, but may present as hemoperitoneum, small bowel obstruction, or volvulus. Pre-operative diagnosis of a mesodiverticular band is often difficult and they are most commonly diagnosed intraoperatively. Treatment should include surgery and may include simple lysis of the band, bowel resection, or more extensive resection if other pathology is present.

Gastric volvulus (GV) is a rare condition characterized by the rotation of all or part of the stomach around its transversal or longitudinal axis. We report the case of a 76-year-old woman with the acute form of GV, likely exacerbated by hiatal hernia and age-related ligamentous relaxation, evolving for a week before her admission. She underwent a midline laparotomy with fundoplication at 270° and anterior gastropexy. GV poses life-threatening risks in its acute presentation. Surgical management entails restoring the hemodynamic stability, surgical detorsion of the volvulus, and addressing the etiology (hiatal hernia).

INTRODUCTION
Congenital causes of duodenal obstruction can be grouped into intrinsic and extrinsic causes. The degree of obstruction caused by such etiologies determines the severity and timing of symptom presentation. Early neonatal diagnosis is common in patients with etiologies that present with high degrees of obstruction such as atresia whereas etiologies that cause lesser degrees of obstruction such as malrotation and duodenal stenosis can go undiagnosed into adulthood.
PRESENTATION OF CASE
We report a case of a 24-year-old female who presented with acute on chronic abdominal pain with bilious vomiting. She was diagnosed with intermittent small bowel volvulus which resolved spontaneously but was found to have adult intestinal malrotation diagnosed intraoperatively. She had a Ladd procedure done but had persistent obstructive small bowel symptoms after the Ladd procedure. She was found to have duodenal stenosis from fibrosis of the duodenum on relaparotomy which was treated surgically with Heineke-Mikulicz strictureplasty leading to total resolution of symptoms.
DISCUSSION
Congenital extrinsic and intrinsic causes of partial duodenal obstruction such as Ladd bands in malrotation and duodenal stenosis respectively, can co-exist and persist into adulthood due to their lesser symptomatology and degree of obstruction. Surgical treatment must identify and correct both conditions when they co-exist to ensure complete resolution of symptoms.
CONCLUSION
This case report highlights the association of duodenal stenosis with adult malrotation which may account for persistent symptoms after the Ladd procedure and suggests the use of Heineke-Mikulicz strictureplasty as a complementary procedure for complete symptom resolution.

Virtual screening, MMGBSA, and molecular dynamics approaches for identification of natural products from South African biodiversity as potential pi-class glutathione S-transferase inhibitors.
We investigated 1012 molecules from natural products previously isolated from the South African biodiversity (SANCDB, https://sancdb.rubi.ru.ac.za/), for putative inhibition of pi-class glutathione -transferase (Ov-GST2) by virtual screening, MMGBSA, and molecular dynamics approaches. ADMET, docking, and MMGBSA shortlisted 12 selected homoisoflavanones-type hit molecules, among which two namely SANC00569, and SANC00689 displayed high binding affinities of -46.09 and -46.26 kcal mol-1, respectively towards π-class Ov-GST2, respectively. The molecular dynamics results of SANC00569 showed the presence of intermolecular H-bonding, hydrophobic interactions between the ligand and key amino acids of Ov-GST2, throughout the simulation period. This hit molecule had a stable binding pose and occupied the binding pockets throughout the 200 ns simulation. To the best of our knowledge, there is no report of any alleged anti-onchocerciasis activity referring to homoisoflavanones or flavonoids. Nevertheless, homoisoflavanones, which are a subclass of flavonoids, exhibit a plethora of biological activities. All these results led to the conclusion that SANC00569 is the most hypothetical Ov-GST2, which could lead the development of new drugs against pi-class glutathione -transferase. Further validation of these findings through in vitro and in vivo studies is required.

BACKGROUND Jejunal diverticulosis are false diverticula of the small bowel that form from outpouching of the mucosa and submucosa. They are pulsion diverticula that are often asymptomatic and can be found incidentally during surgery. In some instances, jejunal diverticula could result in intestinal obstruction. Small intestinal volvulus is an uncommon cause of small bowel obstruction that results in a closed loop obstruction and is an indication for emergent surgical intervention. CASE REPORT We report a case of an 84-year-old man who presented to the Emergency Department with abdominal pain and generalized weakness. A preoperative computerized tomographic scan demonstrated a closed loop small bowel obstruction with mesenteric swirling. The patient was taken for a diagnostic laparoscopy, which revealed extensive proximal jejunal diverticulosis and a volvulus of the involved jejunum. An exploratory laparotomy was warranted for safe detorsion of the small bowel and resection of the diseased segment. The small bowel was successfully detorsed, with resection of the involved jejunum. Intestinal continuity was established by a primary side-to-side anastomosis. CONCLUSIONS Jejunal diverticula have been reported in the literature as a cause of small bowel obstructions, and very few reports exist of concurrent small bowel volvulus. In very rare instances, both of these conditions can coexist. There should be prompt surgical intervention in all cases of closed loop small bowel obstructions to prevent intestinal ischemia, perforation, and sepsis.

BACKGROUND
Lymphangiomas in the gastrointestinal tract are extremely rare in adults. As a benign lesion, small intestine lymphangiomas often remain asymptomatic and pose challenges for definitive diagnosis. However, lymphangiomas can give rise to complications such as abdominal pain, bleeding, volvulus, and intussusception. Here, we report a case of jejunal cavernous lymphangioma that presented with intermittent melena and refractory anemia in a male adult.
CASE SUMMARY
A 66-year-old man presented with intermittent melena, fatigue and refractory anemia nine months prior. Esophagogastroduodenoscopy and colonoscopy were performed many times and revealed no apparent bleeding. Conservative management, including transfusion, hemostasis, gastric acid secretion inhibition and symptomatic treatment, was performed, but the lesions tended to recur shortly after surgery. Ultimately, the patient underwent capsule endoscopy, which revealed a more than 10 cm lesion accompanied by active bleeding. After single-balloon enteroscopy and biopsy, a diagnosis of jejunal cavernous lymphangioma was confirmed, and the patient underwent surgical resection. No complications or recurrences were observed postoperatively.
CONCLUSION
Jejunal cavernous lymphangioma should be considered a cause of obscure gastrointestinal bleeding. Capsule endoscopy and single-balloon enteroscopy can facilitate diagnosis. Surgical resection is an effective management method.

Wandering spleen is a rare condition in children that is often caused by the loss or weakening of the splenic ligaments. Its clinical presentation is variable; 64% of children with wandering spleen have splenic torsion as a complication. A 13-year-old boy who had been showing abdominal pain in the hypogastric region accompanied by vomit and an enormous tumefaction in the suprapubic region came to our observation. Considering the ovoid morphology at ultrasound exam, the echostructure and the marked reduction of parenchymal vascularization, suspicion for torsion of an ectopic spleen arose. Ultrasound evaluation has a primary role in the diagnosis of a suspected wandering spleen and, to avoid potentially life-threatening complications, immediate surgery is often times required.

INTRODUCTION
Gallbladder volvulus is the rarest form of gall bladder pathology and it is also rare cause of acute abdomen. The exact etiology of gallbladder volvulus is undetermined and mostly mimics acute cholecystitis which delays diagnosis and management of patients.
CASE PRESENTATION
In this case report we present 7 years old male child who underwent exploratory laparotomy and intraoperative findings of 360 degree twisted, frankly gangrenous, and perforated at the fundus of the gallbladder. Cholecystectomy was done and the patient had smooth post-operative course and discharged improved.
CLINICAL DISCUSSION
Gallbladder volvulus is a rare cause of acute abdomen especially in pediatric population and it mostly mimics acute acalculous cholecystitis leading to delayed diagnosis and increased risk of complications such as gallbladder gangrene, perforation, bile peritonitis, morbidity and mortality.
CONCLUSION
Even though gallbladder volvulus is rare as cause of acute abdomen, one has to consider in the differential diagnosis as high index of suspicion is important for early diagnosis and management.

BACKGROUND
The Sud-Ouest region of Burkina Faso (especially the Bougouriba valley) has been historically problematic with respect to onchocerciasis control, with a recrudescence of infections after vector control carried out the WHO Onchocerciasis Control Programme was halted in 1989. After 1996, mass drug administration of ivermectin was instigated to control the recrudescence so that it would no longer constitute a public health problem. However, in 2010 WHO changed its recommended policy from control to elimination, and in 2013 biannual Community-Directed Treatment with Ivermectin (CDTI) was instigated. Epidemiological surveys were carried-out in 2011 and 2018 to determine whether CDTI was producing a decline in infection levels and progress towards elimination.
METHODOLOGY/PRINCIPAL FINDINGS
A cross-sectional study was conducted across 20 villages in four health districts in 2011 and 29 villages in 2018. Individuals aged five years and above were examined by skin-snip, and the prevalence and microfilarial load was determined for each village. In 2011, 75% of villages had some infections and 20% had prevalences >5%, with a mean prevalence across all villages of 2.63% (range 0.0-9.7%), and community microfilarial load ranging from 0 to 0.25 microfilariae per biopsy. In 2018, nine villages (= 31% of total) had some infections, with prevalences ranging from 0.41% to 3.54%, and a mean prevalence across all villages of 0.37%. Community microfilarial load ranged from 0 to 0.1. Amongst those people found to be microfilarial positive, 87% had a history of migration.
CONCLUSIONS/SIGNIFICANCE
The endemicity of onchocerciasis infection in the Sud-Ouest region has declined to low levels and seems to be progressing towards elimination. Our findings indicated that biannual CDTI is having good effect, but it should continue for a number of years to ensure elimination of transmission. However, progress towards elimination has a troublesome history in this region, and it would be advisable to select more sentinel villages to have confidence in any future epidemiological and entomological surveys, especially Stop-MDA surveys. With positive individuals migrating between countries, cross-border collaboration needs more attention to ensure effective treatment for onchocerciasis elimination.
