BACKGROUND
Indocyanine green fluorescence angiography, a validated noninvasive imaging technique, is used to assess tissue vascularization. Here, we report three infant patients who underwent intraoperative indocyanine green fluorescence angiography and suffered from postoperative complications caused by the lack of weak fluorescent intestinal resection and assessed residual intestinal perfusion.
CASE PRESENTATION
We observed the clinical characteristics and operative findings of patients treated from January 2022 to December 2022. Indocyanine green (0.5 mg/kg) was intravenously injected. The first patient was a 29-day-old girl with surgical necrotizing enterocolitis who underwent intraoperative indocyanine green fluorescence angiography at the first- and second-look operations. The proximal jejunum was difficult to diagnose to detect blood flow during the second-look operation. The second patient was a 32-day-old boy with surgical necrotizing enterocolitis. A part of the antimesenteric mucosa of the patient that exhibited weak fluorescence was preserved; however, it formed postoperative hematomas. The third patient was a 30-day-old boy with midgut volvulus. Weak fluorescence in the intestinal wall was observed 5 cm of the small intestine from the ileocecal valve was preserved, but it formed a stricture, and the patient underwent ileocecal resection after 30 days.
CONCLUSIONS
Weak fluorescence in the intestine in infants by performing indocyanine green fluorescence angiography is associated with a high risk of non-recovering ischemic lesions and postoperative complications.

Cerebral palsy (CP) is a neurodevelopmental disorder that affects motor function and is often accompanied by secondary musculoskeletal issues. Severe scoliosis, a lateral curvature of the spine over 40 degrees, poses a significant challenge for individuals with CP, impacting their mobility and overall well-being. While the association between scoliosis and gastrointestinal complications is acknowledged, the occurrence of colonic volvulus with necrosis in the context of CP and severe scoliosis is rare and complex. This case report emphasizes the importance of clinical awareness in managing gastrointestinal complications in patients with CP and severe scoliosis. An 11-year-old female presented with gastroenteritis and a concurrent viral upper respiratory tract infection. She experienced complications such as greenish vomiting, hematemesis, abdominal distention, and constipation. The patient has a medical history of epilepsy and was diagnosed with quadriplegic CP at four months old due to viral meningitis. She is currently on anti-epileptic medications and receives regular follow-ups with neurology. Severe lumbar scoliosis of more than 50 degrees Cobb angle is also noted. Physical examination revealed dehydration, bilious content in nasogastric tube (NGT) aspiration, tender abdomen, and an empty digital rectal examination. Some laboratory findings showed elevated levels of erythrocyte sedimentation rate (ESR), prothrombin time (PT), blood urea nitrogen (BUN), and sodium, while albumin levels were decreased, and white blood cell (WBC) count was mildly elevated. Abdominal computed tomography (CT) with contrast showed a distended ascending colon with air and swirling of the mesentery. The distal half of the large bowel was not dilated, and fecal matter was present. The small bowel appeared to be collapsed, and there was moderate free fluid in the peritoneal cavity, indicating colonic volvulus involving the proximal large bowel. The patient underwent surgery, which involved deflating and removing the distended colon, resecting the gangrenous colon, and performing an ilio-sigmoid anastomosis to restore gastrointestinal continuity. Postoperatively, the patient received close monitoring in the pediatric intensive care unit (PICU), received total parenteral nutrition (TPN) for five days, gradually progressed feeding, and showed overall improvement in her condition. In conclusion, this case report highlights a rare occurrence of colonic volvulus in a patient with CP and severe scoliosis. It emphasizes the complex relationship between neurological and musculoskeletal disorders in gastrointestinal complications. A multidisciplinary approach is important for optimal management. It shows the importance of musculoskeletal factors in patients with neurological conditions. Overall, it contributes to the medical literature and emphasizes tailored management strategies for gastrointestinal issues in such patients.

This case series describes the post-mortem findings in 17 bitches (Canis lupus familiaris) with a recent (<7 days) history of caesarean section, most (94%) of which had undergone conservative caesarean section with preservation of the uterus. Brachycephalic breeds accounted for 71% of all cases, with the French Bulldog (35%, n = 6), English Bulldog (18%, n = 3) and Boston Terrier (12%, n = 2) overrepresented. Eleven animals (65%) died between 4 and 48 h after surgery, whereas six (35%) died during the procedure. The most common cause of death was septicaemia (41%, n = 7) associated with Streptococcus canis (29%, n = 5) and/or Escherichia coli (24%, n = 4). Other causes of death included brachycephalic obstructive airway syndrome (BOAS)-associated respiratory failure (24%, n = 4), haemorrhagic shock (18%, n = 3), inconclusive (12%, n = 2) and gastric dilatation and volvulus (6%, n = 1). Histopathological changes were seen in the uterus of 10 cases and included marked inflammation (60%, n = 6), marked haemorrhage (20%, n = 2) or both (20%, n = 2). Metritis was often characterized by fibrinonecrotic, neutrophilic to mixed inflammation, consistent with acute infection. However, prominent lymphohistiocytic infiltrates in two cases suggested that infection had been present prior to surgery. Peritonitis, myositis and panniculitis commonly (35%, n = 6) surrounded the incision sites. The presence of inflammation and bacterial colonies within multiple surgical sites suggested iatrogenic implantation of bacteria, potentially from the uterine lumen. Bacterial culture and isolation, as well as tape measurements for evaluation of conformational BOAS risk factors where applicable, are recommended as part of the routine post-mortem work-up for bitches that die shortly after caesarean section.

The occurrence of small intestinal diverticula is relatively infrequent compared to its counterpart in the large bowel. Duodenal diverticula exhibit a significantly higher prevalence within the small intestine compared to jejunoileal diverticula, with a ratio of five to one. The occurrence of jejunoileal diverticula exhibits considerable variability and has been documented to range from 0.5% to 2.3% in radiographic series, while autopsy studies have reported rates as high as 7%. We present the clinical details of a 65-year-old male patient who sought medical attention due to a constellation of symptoms, including abdominal pain, vomiting, and obstipation. After adequate resuscitation with IV fluids and preoperative preparation, the patient was transported to the operating room for an emergency exploratory laparotomy. Multiple jejunal diverticuli were identified in the proximal jejunum at the antimesenteric border, less than three feet from the duodenojejunal (DJ) junction. The terminal ileum was found to be 360° rotated counterclockwise around the small bowel mesentery, causing the small intestine to appear congested; however, after clockwise de-rotation, the small bowel regained its normal color. Adhesiolysis and small bowel decompression were performed, and the patient had an uneventful recovery.

BACKGROUND
Maridi County is an onchocerciasis-endemic area in South Sudan. Annual community-directed treatment with ivermectin (CDTi) was instituted in Maridi since the early 2000s, but with low coverage. In 2021, the CDTi programme was strengthened to a six-monthly programme. Additionally, the community-based vector control strategy "Slash and Clear" has been implemented since 2019 at the Maridi Dam, the only blackfly breeding site in the area. This study assessed the effect of these reinforced onchocerciasis elimination interventions on the seroprevalence among young children, an indicator of ongoing transmission.
METHODS
Baseline and follow-up serosurveys were conducted in Maridi in 2019 (prior to strengthening onchocerciasis elimination efforts) and 2023, respectively. During both surveys, children aged three to nine years were recruited from five study sites situated at different distances from the Maridi Dam. Ov16 antibodies were detected via rapid diagnostic tests (RDTs) using whole blood obtained by finger-pricking the participants. Baseline and follow-up Ov16 prevalence rates were calculated and compared.
RESULTS
In 2019, the Ov16 seroprevalence among children aged three to nine years was 24.5% compared to 30.6% in 2023 (p=0.22). Both surveys found a particularly high Ov16 seroprevalence in the study site closest to the Maridi Dam (35.0% in 2019 and 44.0% in 2023, p=0.52). The Ov16 seroprevalence had a non-significant decreasing trend in the three-year-old children, from 12.5% (3/24) in 2019 to 8.8% (3/34) in 2023 (p=0.65).
CONCLUSION
The persistent Ov16 RDT seropositivity among three-year-old children in 2023 indicates ongoing transmission. Therefore, further strengthening of the onchocerciasis elimination programme is required. The study highlights the utility of RDTs in monitoring onchocerciasis transmission in highly endemic settings.

A better understanding of the function of neutrophil extracellular traps (NETs) may facilitate the development of interventions for sepsis. The study aims to investigate the formation and degradation of NETs in three murine sepsis models and to analyze the production of reactive oxygen species (ROS) during NET formation. Murine sepsis was induced by midgut volvulus (720° for 15 min), cecal ligation and puncture (CLP), or the application of lipopolysaccharide (LPS) (10 mg/kg body weight i.p.). NET formation and degradation was modulated using mice that were genetically deficient for -KO) or and -DKO). After 48 h, mice were killed. Plasma levels of circulating free DNA (cfDNA) and neutrophil elastase (NE) were quantified to assess NET formation and degradation. Plasma deoxyribonuclease1 (DNase1) protein levels, as well as tissue malondialdehyde (MDA) activity and glutathione peroxidase (GPx) activity, were quantified. DNase1 and DNase1L3 in liver, intestine, spleen, and lung tissues were assessed. The applied sepsis models resulted in a simultaneous increase in NET formation and oxidative stress. NET formation and survival differed in the three models. In contrast to LPS and Volvulus, CLP-induced sepsis showed a decreased and increased 48 h survival in -KO and -DKO mice, when compared to WT mice, respectively. -KO mice showed decreased formation of NETs and ROS, while -DKO mice with impaired NET degradation accumulated ROS and chronicled the septic state. The findings indicate a dual role for NET formation and degradation in sepsis and ischemia-reperfusion (I/R) injury: NETs seem to exhibit a protective capacity in certain sepsis paradigms (CLP model), whereas, collectively, they seem to contribute adversely to scenarios where sepsis is combined with ischemia-reperfusion (volvulus).

We hereby present a 70-year-old male Ethiopian farmer who presented with clinical manifestations suggestive of acute large bowel obstruction, which had persisted for 3 days. Over the past 3 years, he has experienced three similar recurring episodes, which were alleviated by decompression using a rectal tube. Upon initial examination, the patient displayed signs of cardiopulmonary distress, although no indications of peritonitis were observed. Further evaluation through plain abdominal and chest X-rays revealed findings consistent with sigmoid volvulus, as well as mediastinal shift, elevated diaphragm, and a right-positioned heart. Consequently, a sigmoid resection and an end colostomy were done. The patient showed improvement and was discharged from the hospital on the 14th day following the surgery. It is atypical for an individual to present with acute sigmoid volvulus accompanied by a mediastinal shift resulting from mass action on the hemidiaphragm. Therefore, it may be imperative to involve a pulmonologist in managing this rare situation. By ensuring that the surgical team is well-informed in such circumstances, patients can receive enhanced care and treatment.

Gallbladder volvulus (GV) is a medical emergency and a rare cause of acute abdominal pain among the pediatric population. GV is more prominent usually in boys in pediatric patients. If it is not diagnosed and surgically intervened promptly, GV will become a life-threating condition. Fortunately, a safe and effective laparoscopic cholecystectomy is now widely indicated. A 5 years old female patient with abdominal pain and heavy much vomiting was referred to the emergency room in our hospital. She was suspiciously diagnosed with acute inflammation of the gallbladder according to the results of abdominal ultrasound and computerized tomography (CT) scan already performed on admission. One day after the hospitalization, abdominal ultrasound, and CT scan were performed again because of intensification of her abdominal pain and revealed the clinical portrait of GV such as a "floating gallbladder" sign, an echogenic cone structure, an elongated axis displaced horizontally instead of vertically and a lack of intramural blood flow. The acute GV diagnosis was made and the patient was operated, using the laparoscopic cholecystectomy on time, the gallbladder was tightly twisted clockwise at approximately 720°. The operation and postoperative treatment went quite well and the patient was discharged from the hospital on postoperative Day 7. GV is very rare in children, easily omitted or misdiagnosed with cholecystitis. Imaging diagnosis such as ultrasound, CT with contrast helps make diagnosis promptly that avoids severe complications such as gallbladder perforation, necrosis, and biliary peritonitis.

BACKGROUND
Onchocerciasis causes chronic systemic inflammation. Several studies have used markers such as haemato-biochemical indices to predict the occurrence of systemic inflammation. This study assessed the variability and predictability of haemato-biochemical indices and blood composite ratios (BCRs) in microfilariae positive (MF+) and microfilariae negative (MF-) subgroups of onchocercomata participants.
METHODS
One hundred and five (105) MF + and 34 MF- participants were retrospectively recruited into the study. Screening for the presence of O. volvulus microfilariae was done from skin snips taken from the left and right iliac crests of participants using established and approved protocols. Haematological and biochemical indices were measured using standard laboratory automated analyzers. Blood composite ratios (BCRs) were calculated as ratios of the absolute parameters involved.
RESULTS
A significantly increased total WBC, absolute eosinophil, eosinophil percent and absolute basophil were observed in the MF + participants compared to MF- participants. Reduced gamma-glutamyl transferase (GGT) with increased estimated glomerular filtration rate (eGFR) was significantly associated with MF + participants compared to MF- participants. BCRs were significantly higher for eosinophil-to-neutrophil ratio (ENR), eosinophil-to-monocyte ratio (EMR), eosinophil-to-basophil ratio (EBR) and eosinophil-to-lymphocyte ratio (ELR) in MF + participants compared to MF- participants. After multivariate adjustment, onchocercomata participants with increased eosinophil counts (aOR = 13.86, 95% CI [2.07-92.90], p = 0.007), ENR x10 (aOR = 1.42, 95% CI [1.05-1.93], p = 0.025), EMR (aOR = 2.64, 95% CI [1.25-5.60], p = 0.011), EBR (aOR = 1.07, 95% CI [1.01-1.10], p = 0.020) and ELR x10 (aOR = 1.69, 95% CI [1.14-2.51], p = 0.009) were more likely to have microfilaridermia.
CONCLUSIONS
Elevated eosinophil counts with higher ENR, EMR, EBR and ELR levels are significantly associated with microfilaridermia in onchocercomata participants. Combining BCRs with eosinophil count significantly led to an improvement in the conventional model for predicting microfilaridermia.
