Intestinal malrotation with volvulus is generally presented as a bilious vomiting and acute intestinal obstruction in the newborn period. It could compromise vascular supply of the small bowel secondary to torsion of superior mesenteric artery (SMA) and without urgent surgical management, it could lead to detrimental outcomes such as transmural bowel infarction and sepsis. However, in chronic cases, it is rarely obstructs the vascular supply and propagates to an acute bowel infarction. Rarely, chronic malrotation with midgut volvulus may not reduce the mesenteric blood supply because of collateral vessels, and the chronically stagnated blood flow of the superior mesenteric vein (SMV) favors thrombus formation within the lumen. The recommended treatment is Ladd's procedure and anticoagulation therapy. The authors present an unusual case of intestinal malrotation with chronic volvulus resulting in superior mesenteric vein and portal vein thrombosis in a 28-year-old patient.

An 18-year-old miniature Appaloosa stallion presented with 6 months of history of sanguineous crusts on medial hind limbs and discomfort of micturition. Cauliflower-like and small masses were treated with cryotherapy for 6 months, but the regrowth of masses occurred. Subsequently, local excision via laser and topical treatment with 5% 5-fluorouracil for 5 months were followed. However, the horse was euthanized 4 months later due to regrowth of the masses. The mass was diagnosed as penile papilloma with cellular atypia and Equus caballus papillomavirus type 2 (EcPV-2) DNA was detected. This is the first report of equine penile neoplasm with EcPV-2 infection in Asia.

BACKGROUND AND OBJECTIVES: It is not clear which mucins are responsible for the mucus hypersecretion in allergic rhinitis and allergic asthma. Recently, it was found that IL-13 is closely related to allergic inflammation and mucus hypersecretion in in vivo animal models. However, the role of IL-13 in in vitro cellular models has yet to be determined. This study aimed to investigate the direct effect of IL-13 on mucin gene expression and mucin secretion in cultured normal human nasal epithelial cells. MATERIALS AND METHOD: Cells were cultured with passage-2 normal human nasal epithelial cells using the air-liquid interface culture method. After treatment with IL-13, the total mucin and MUC5AC mucin levels were measured using the immuno-blotting assay. The MUC2, MUC5AC, and MUC8 mRNA expressions were measured using RT-PCR. Immunostaining was also performed using a MUC5AC antibody on histologic and cytospin slides. RESULTS: After treatment with 5 ng/ml or more of IL-13, the level of total mucin and MUC5AC mucin secretion decreased substantially. The expression of MUC2 and MUC8 mRNA increased with higher concentrations of IL-13, but the expression of MUC5AC mRNA decreased. On the 7th day after IL-13 treatment, a significant decrease in the number of MUC5AC-positive cells was confirmed with immunostaining. CONCLUSION: These findings indicate that IL-13 suppresses MUC5AC mucin gene expression and mucin secretion in cultured normal human nasal epithelial cells in vitro.

This following case report describes the open reduction, internal fixation and the reconstruction of an extensive comminuted mandibular fracture with bilateral condylar fractures in a 19-year-old male patient with an intellectual disability and autistic disorder. He suffered fall trauma, resulting in shattered bony fragments of the alveolus and mandibular body between both mandibular rami, the fracture of both condyles and the avulsion or dislocation of every posterior tooth of the mandible. The patient underwent open reduction and internal fixation between both mandibular rami using a reconstruction plate, open reduction and internal fixation of the shattered fragments using miniplates and screws, and the closed reduction of the bilateral condylar fractures.

Capsule endoscopy (CE) is a preferred diagnostic method for analyzing small bowel diseases. However, capsule endoscopes capture a sparse number of images because of their mechanical limitations. Post-procedural management using computational methods can enhance image quality. Additional information, including depth, can be obtained by using recently developed computer vision techniques. It is possible to measure the size of lesions and track the trajectory of capsule endoscopes using the computer vision technology, without requiring additional equipment. Moreover, the computational analysis of CE images can help detect lesions more accurately within a shorter time. Newly introduced deep leaning-based methods have shown more remarkable results over traditional computerized approaches. A large-scale standard dataset should be prepared to develop an optimal algorithms for improving the diagnostic yield of CE. The close collaboration between information technology and medical professionals is needed.

Background: Pulmonary surfactant (PS) replacement therapy, as a safe and effective treatment for respiratory distress syndrome (RDS) may have further increased with the extended insurance coverage since 2011 in Korea. Thus, this study aimed to investigate the epidemiologic data of PS replacement therapy for RDS in Korea and to analyze the complications associated with RDS. Methods: We included 19,442 infants who were treated with PS and diagnosed with RDS (International Classification of Diseases-10 codes: P22.0) between 2014 and 2018 from the Health Insurance Review and Assessment database. Birth certificate data from Statistics Korea were used to estimate the incidence of RDS. Results: The average incidence of RDS within the study period was 0.99% among live births.Repeated doses of PS were administered to 1,688 infants (8.7%), ranging from 2 doses in 929 infants (4.8%) to 9 doses in 1 infant (0.01%). The incidence of RDS in term infants markedly increased over 5 years from 0.2% to 0.34%. The incidence was similarly increased among the preterm infants. The RDS mortality rate was 6.3% and showed a decreasing trend according to year. The mortality rate was significantly higher in the lower gestational age group. A decreasing trend was observed in the incidence of the complications, such as patent ductus arteriosus, intraventricular hemorrhage, and bronchopulmonary dysplasia, except for pneumothorax in term infants. The complications were also higher in the lower gestational age group and the lower birth weight group. However, pneumothorax was the most frequent complication in the term infant group and in infants with birth weight ≥ 2,500 g. Conclusion Advancements in neonatal care and extended insurance coverage have increased the use of PS replacement therapy for RDS. This, in turn, decreased neonatal mortality and the incidence of the associated complications. The appropriate therapeutic strategy for RDS should be decided according to the gestational age and lung pathology.
