Biliary ascites due to spontaneous biliary duct perforation is a rare case presentation usually seen in the paediatric age group of 6-36 months. We are presenting the case of a 14-month-old baby with abdominal distention associated with abdominal pain, vomiting, fever, and a history of no passage of stools. Upon examination, the abdomen was tense and tender. On radiological investigations, gross free fluid was present in the abdominal cavity along with bowel obstruction and partial situs inversus of the spleen and stomach. The bowel obstruction was relieved by rectal stimulation, after which oral feeds were well tolerated. Bilious fluid was found on diagnostic paracentesis, confirming the diagnosis. The patient was managed further by broad-spectrum antibiotics and drainage of the free fluid. The management ranges from conservative treatment to Roux-en-Y anastomosis. A non-surgical diagnosis is uncommonly seen and helps improve the patient\'s prognosis if detected early. This case report highlights the importance of early diagnosis and non-surgical treatment modality in critical patients.

Bothersome gastrointestinal (GI) signs/symptoms, including abdominal pain, distension, nausea, and flatulence, are common in children. A diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) is frequently recommended for children with GI symptoms. Currently, there are no studies on the effect of FODMAPs in healthy schoolchildren. In this cross-sectional study, schoolchildren reported an association between FODMAPs and GI symptoms through a standardized questionnaire and images of 20 common staples known to be rich in FODMAPs. A total of 208 schoolchildren aged 8-18 years old participated. A proportion of 38.0% of children reported GI symptoms, with abdominal pain (33%) being the most common complaint followed by abdominal distension (24%) and nausea (23%). The majority of children who reported intolerances to FODMAP-containing foods were intolerant to less than two food groups (76%). While vegetables and legumes (26%), particularly black beans (11%) and onions (7%), emerged as the most common group of triggers, milk (12%) stood out as the single food most frequently associated with GI symptoms. In conclusion, there was a high prevalence of FODMAPs intolerance among schoolchildren. Larger studies are recommended to confirm these findings and to inform possible dietary interventions to reduce the effect of FODMAPs on schoolchildren.

Vascular hamartomas represent a focal proliferation of disorganized vascular tissue, which is usually present at birth. An 8-month-old Scottish fold female cat presented with abdominal distention, mild dyspnea, pale mucous membranes, and lethargy. Ultrasound examination revealed a hepatic mass resembling multiple cysts affecting the right medial lobe. Surgical excision was performed, and tissue samples were sent for histopathological evaluation. The mass was composed of multiple, dilated, variably-sized well-differentiated arterioles and venules, consistent with vascular hamartoma. Immunohistochemical investigation of the cells lining the cystic structures showed positive immunolabeling for vimentin and negative immunolabeling for PanCK, supporting the histological diagnosis. Based on existing literature, this represents the first case of hepatic localization of vascular hamartoma in a cat. In addition, a comparative histological study between vascular hamartoma and biliary duct hamartoma and a review on hepatic vascular hamartomas in animals and hepatic cystic masses in cats was made.

Ogilvie\'s syndrome is a colonic pseudo-obstruction that results in colonic dilation without a mechanical obstruction. We discuss a 33-year-old, 36-week pregnant, G1P0L0A0 female who presented with severe pre-eclampsia. Less than 24 hours after induction by vaginal delivery, she developed significant abdominal pain and distention. On a CT scan of the abdomen and pelvis, she was diagnosed with Ogilvie\'s syndrome due to a finding of large bowel dilation with an abrupt transition point at the splenic flexure without a noted mass. She was initially treated conservatively with nasogastric tube decompression and IV fluid resuscitation. When these conservative measures failed, neostigmine was administered with transient improvement in symptoms. Despite the appropriate administration of neostigmine and initial relief of symptoms with stool output, the patient ultimately required surgical intervention with the creation of a transverse loop colostomy. The development of Ogilvie\'s syndrome in the postpartum period is a very rare finding, particularly after a vaginal delivery.

Our case report highlights pseudocyesis, a rare medical condition in a 40-year-old woman with comorbid major depressive disorder. Cultural influences on experiences, and the need for understanding sociocultural factors in mental health, are emphasized in low-resource settings.

Testicular seminoma commonly occurs in young men aged between 15 and 45 years old. Those with testicular cancer may present with a lump or swelling in the testicle. If treated and managed early, patients can expect a greater than 95% success rate. However, advanced stages of testicular seminoma can lead to eventual metastasis. We present a 45-year-old male patient with a prior history of testicular seminoma who was admitted to the emergency department with abdominal distension and acute abdominal pain. The CT identified a rather sizable abdominal mass and the biopsy confirmed metastatic testicular seminoma. Lymphoma was considered as the other differential diagnosis. Abdominal metastasis is rare in patients with testicular seminoma and usually leads to a poor survival outcome. Our patient did not attend follow-up appointments postorchidectomy, likely resulting in abdominal metastasis of testicular seminoma. This demonstrates the importance of ongoing surveillance of seminoma patients, and the challenges associated with differentiating large abdominal conglomerate mass in the CT scan. This patient is currently on active chemotherapy with bleomycin, cisplatin, and etoposide.

BACKGROUND: Adults with food-protein-induced enterocolitis syndrome (FPIES) often develop severe abdominal symptoms after eating seafood. However, no investigation of a food elimination strategy for adult FPIES patients has been performed to date.
METHODS: We conducted a retrospective cohort study of seafood-avoidant adults by telephone interview, based on the diagnostic criteria for adult FPIES reported by González et al. We compared the clinical profiles, abdominal symptoms, and causative seafoods between FPIES and immediate-type food allergy (IgE-mediated FA) patients. We also profiled the detailed intake-status of seafoods in adult FPIES patients.
RESULTS: Twenty-two (18.8 %) of 117 adults with seafood-allergy were diagnosed with FPIES. Compared with the IgE-mediated FA patients, FPIES patients had an older age of onset, more pre-existing gastrointestinal and atopic diseases, more episodes, longer latency and duration of symptoms, more nausea, abdominal distention, and severe abdominal pain, and more frequent vomiting and diarrhea. In particular, abdominal distention-reflecting intestinal edema and luminal fluid retention-may be the most distinctive characteristic symptom in adult FPIES (p < 0.001). Bivalves, especially oysters, were the most common cause of FPIES. Strikingly, intake-status profiling revealed that many FPIES patients can safely ingest an average of 92.6 % of seafood species other than the causative species.
CONCLUSIONS: There are many differentiators between FPIES and IgE-mediated FA, which may reflect differences in the underlying immunological mechanisms. Although seafood FPIES is unlikely to induce tolerance, many patients can ingest a wide variety of seafood species after a long period from onset.

Diseases of the gastrointestinal system may be congenital or acquired. Intestinal obstruction is common in children and neonates, and it has various causes. Obstructions due to congenital adhesion bands are rare. Few cases were reported in the literature. In this paper, we will discuss the case of an 8-day-old girl who was presented to the emergency department with signs of intestinal obstruction.

Food protein-induced enterocolitis syndrome (FPIES) is increasingly found in adults. FPIES requires different treatment from immediate-type food allergy (FA) in emergency medicine. However, no comparison of the clinical presentations of these diseases has been reported.
To compare the clinical presentations and causative crustaceans of adult FPIES and FA using a standardized questionnaire and to thereby lay the groundwork for establishing an algorithm that distinguishes those diseases.
We conducted a retrospective cohort study of crustacean-avoidant adults by telephone interview based on the previously reported diagnostic criteria for adult FPIES to compare the clinical features and crustacean intake status between FPIES and FA.
Of 73 adult patients with crustacean allergy, 8 (11%) were diagnosed with having FPIES and 53 (73%) FA. Compared with the patients with FA, those with FPIES had a longer latency period (P < .01), more episodes (P = .02), longer duration of symptoms (P = .04), more frequent abdominal distention (P = .02), and severe colic pain (P = .02). Half of the patients with FPIES experienced fear of death during an episode. Panulirus japonicus (Japanese spiny lobster) and Homarus weber (lobster) were significantly common FPIES-causing foods. A statistically significant 62.5% of patients with FPIES were able to ingest some type of crustacean.
FPIES and FA can be clearly differentiated by the abdominal symptoms, latency period, and duration of episodes. Furthermore, some patients with FPIES do not necessarily need to avoid all crustaceans. Our findings lay the groundwork for establishing an algorithm that distinguishes FPIES from FA in adults.

This case report describes an infant with failure to thrive and progressive abdominal distention that ultimately led to a rare diagnosis of chylomicron retention disease at 1 year of life. Laboratory abnormalities included increased qualitative stool fat, along with low apolipoprotein B, high-density lipoprotein, low-density lipoprotein (LDL), and total cholesterol in blood. In chylomicron retention disease, diarrhea has been reported as the most common presenting symptom followed by failure to thrive and vomiting. Diarrhea and vomiting before 6 months of life have been described in cases of chylomicron retention disease reported in the literature; however, this patient did not present with either of those symptoms. This case report uniquely demonstrates that lack of early or persistent digestive symptoms of diarrhea or vomiting does not exclude a diagnosis of chylomicron retention disease.
