Lacticaseibacillus paracasei Bacteremia Associated With Probiotic Use in a Child With Hypoganglionosis: Case Report and Literature Review.

Probiotics are generally considered safe and used to improve intestinal function. Here, we report a Lacticaseibacillus paracasei bacteremia case in an 8-month-old girl administered probiotics containing L. paracasei after jejunostomy for hypoganglionosis. The patient had persistent bacteremia with L. paracasei and was treated with antimicrobial therapy. The isolate from the blood culture was genetically indistinguishable to the strain contained in probiotics. Bacteremia risk should be considered before probiotic use in patients with underlying compromised immune systems or intestinal integrity.

Postoperative pulmonary vascular growth in patients with congenital diaphragmatic hernia.

BACKGROUND: Postoperative pulmonary growth in congenital diaphragmatic hernias (CDH) remains unclear. We investigated postoperative pulmonary vascular growth using serial lung perfusion scintigraphy in patients with CDH. METHODS: Neonates with left CDH who underwent surgery and postoperative lung perfusion scintigraphy at our institution between 2001 and 2020 were included. Patient demographics, clinical courses, and lung scintigraphy data were retrospectively analyzed by reviewing medical records. RESULTS: Twenty-one patients with CDH were included. Of these, 10 underwent serial lung scintigraphy. The ipsilateral perfusion rate and median age on the 1st and serial lung scintigraphy were 32% (34 days) and 33% (3.6 years), respectively. Gestational age at prenatal diagnosis (p = 0.02), alveolar-arterial oxygen difference (A-aDO2) at birth (p = 0.007), and preoperative nitric oxide (NO) use (p = 0.014) significantly correlated with the 1st lung scintigraphy. No other variables, including operative approach, were significantly correlated with the 1st or serial scintigraphy findings. All patients improved lung perfusion with serial studies [Difference: + 7.0 (4.3-13.25) %, p = 0.001, paired t-test]. This improvement was not significantly correlated with preoperative A-aDO2 (p = 0.96), NO use (p = 0.28), or liver up (p = 0.90). The difference was significantly larger in patients who underwent thoracoscopic repair than in those who underwent open abdominal repair [+ 10.6 (5.0-17.1) % vs. + 4.25 (1.2-7.9) %, p = 0.042]. CONCLUSION: Our study indicated a postoperative improvement in ipsilateral lung vascular growth, which is possibly enhanced by a minimally invasive approach, in patients with CDH.

A case of acquired hemophilia A after pancreaticoduodenectomy for distal cholangiocarcinoma.

Acquired hemophilia A (AHA) is a rare disease that results from factor VIII inhibitors causing abnormal coagulation, and certain cases may develop after highly invasive surgery. The present case study reports on a 68-year-old male patient who developed AHA after undergoing a subtotal stomach-preserving pancreatoduodenectomy for distal cholangiocarcinoma. The patient experienced complications after surgery, requiring reoperation on postoperative day (PD) 5 due to rupture of the Braun's enterostomy. On PD 6, angiography was performed after bleeding was detected in the jejunal limb, but hemostasis occurred spontaneously during the examination. Bleeding was observed again on PD 8 and direct surgical ligation was performed. On PD 14, bleeding recurred in the jejunal limb and angiography was performed to embolize the periphery of the second jejunal artery. During the procedure, the prothrombin time was normal, but only the activated partial thromboplastin time was prolonged. A close examination of the coagulation system revealed a decrease in factor VIII levels and the presence of factor VIII inhibitors, resulting in the diagnosis of AHA. Administration of steroids was initiated on PD 15 and, in addition to daily blood transfusions, activated prothrombin complex concentrate was administered to achieve hemostasis. The patient was discharged from the intensive care unit on PD 36 but later developed an intractable labial fistula due to suture failure at the gastrojejunostomy site. As the use of factor VIII inhibitors continued despite the administration of steroids, cyclophosphamide (CPA) pulse therapy was added at PD 58. However, CPA was ineffective and the administration of rituximab was initiated on PD 98. After 12 courses of rituximab, the patient tested negative for factor VIII inhibitors on PD 219. On PD 289, labial fistula closure was performed with continuous replacement of factor VIII and the patient was discharged on PD 342.

Surgery for acute abdomen in adult patients with severe motor and intellectual disabilities.

Purpose: The present study aimed to examine the characteristics, outcomes, and problems related to surgery for acute abdomen in adult patients with severe motor and intellectual disabilities (MID). Methods: The clinical records of 35 adult patients with severe MID who received emergency surgery for acute abdomen between 2011 and 2020 were reviewed. Results: The median duration from onset to surgery was 48 hours. There were 2 cases of in-hospital mortality (5.7%), and all the patients underwent surgery more than 72 hours after onset. The in-hospital mortality rate was significantly higher in patients who received surgery later than 72 hours after onset. Bowel obstruction was the most common disease among the acute abdomen cases (71.4%) and most often involved volvulus of the small bowel and cecum. Of the patients with bowel obstruction with severe MID, 72.0% had abdominal distention, 16.0% had abdominal pain, and 4.0% had vomiting. The median duration from onset to surgery was significantly longer in the patients with bowel obstruction with severe MID than in those without severe MID (24 hours vs. 16 hours). Conclusion: Acute abdomen in patients with severe MID was often due to bowel obstruction caused by volvulus. Because patients with severe MID have few symptoms, they are susceptible to adverse surgical outcomes associated with a prolonged duration from onset to surgery.
