Purpose: To assess gastric pH and its relationship with urease-test positivity and histological findings in children with Helicobacter pylori infection. Methods: Fasting gastric juices and endoscopic antral biopsy specimens were collected from 562 children and subjected to the urease test and histopathological examination. The subjects were divided into 3 age groups: 0-4, 5-9, and 10-15 years. The histopathological grade was assessed using the Updated Sydney System, while the gastric juice pH was determined using a pH meter. Results: The median gastric juice pH did not differ significantly among the age groups (p=0.655). The proportion of individuals with gastric pH >4.0 was 1.3% in the 0-4 years group, 6.1% in the 5-9 years group, and 8.2% in 10-15 years (p=0.101). The proportions of moderate and severe chronic gastritis, active gastritis, and H. pylori infiltration increased with age (p<0.005). Urease-test positivity was higher in children with hypochlorhydria (77.8%) than in those with normal gastric pH (31.7%) (p<0.001). Chronic and active gastritis were more severe in the former than the latter (p<0.001), but the degree of H. pylori infiltration did not differ (20.9% vs. 38.9%; p=0.186). Conclusion: Gastric pH while fasting is normal in most children regardless of age. Urease-test positivity may be related to hypochlorhydria in children, and hypochlorhydria is in turn related to H. pylori infection.

Hypercoagulability is the most common coagulopathy seen in dogs with neoplasia, whereas a hypocoagulable state is relatively rare. A 16-year-old spayed female miniature Schnauzer presented with bilateral epistaxis, bilateral hindlimb swelling, and lameness. Previously, the dog was diagnosed with intermediate grade solid carcinoma after mastectomy, and then showed generalized ecchymoses on the abdomen and bilateral hindlimbs on presentation. Laboratory tests revealed a hypocoagulable state, including thrombocytopenia, hypofibrinogenemia, and delayed prothrombin and activated partial thromboplastin time. Thromboelastography demonstrated a prolonged K time with a decreased alpha angle and low maximal amplitude, reflecting a decrease in clot strength. The hypocoagulable state of disseminated intravascular coagulopathy was speculated based on the presence of an underlying tumor, clinical symptoms, and laboratory results of the hypocoagulable state. This case shows the incidence of hemostatic dysfunction as a paraneoplastic syndrome in a dog with mammary gland carcinoma.

Background: The objective of this study was to investigate whether alcohol consumption might affect the quality of life (QOL), depressive mood, and metabolic syndrome in patients with obstructive lung disease (OLD). Methods: Data were obtained from the Korean National Health and Nutrition Examination Survey from 2014 and 2016. OLD was defined as spirometry of forced expiratory volume in 1 second/forced vital capacity <0.7 in those aged more than 40 years. QOL was evaluated using the European Quality of Life Questionnaire-5D (EQ-5D) index. Patient Health Questionnaire-9 (PHQ-9) was used to assess the severity of depressive mood. Alcohol consumption was based on a history of alcohol ingestion during the previous month. Results: A total of 984 participants with OLD (695 males, 289 females, age 65.8±9.7 years) were enrolled. The EQ-5D index was significantly higher in alcohol drinkers (n=525) than in non-alcohol drinkers (n=459) (0.94±0.11 vs. 0.91±0.13, p=0.002). PHQ9 scores were considerably lower in alcohol drinkers than in non-alcohol drinkers (2.15±3.57 vs. 2.78±4.13, p=0.013). However, multiple logistic regression analysis showed that alcohol consumption was not associated with EQ-5D index or PHQ-9 score. Body mass index ≥25 kg/m², triglyceride ≥150 mg/dL, high-density lipoprotein <40 mg/dL in men and <50 mg/dL in women, and blood pressure ≥130/85 mm Hg were significantly more common in alcohol drinkers than in non-alcohol drinkers (all p<0.05). Conclusion: Alcohol consumption did not change the QOL or depressive mood of OLD patients. However, metabolic syndrome-related factors were more common in alcohol drinkers than in non-alcohol drinkers.

Acase of malignant schwannoma in the cervico-thoracic region with lung metastasis is presented. The patient was 55-year-old man presented with right arm weakness. Magnetic resonance image demonstrated lobulated enhancing soft tissue masses in spinal canal, neural foramen and right paraspinal space at C7-T1 level compressing the dural sac and spinal cord. Subtotal removal was performed and histological diagnosis of malignant schwannoma was made. Reoperation due to recurrence was done but subsequent metastasis to lung was observed.

Nephrogenic diabetes insipidus (DI) is a rare disease in which the patient cannot concentrate urine despite appropriate or high secretion of antidiuretic hormone. Congenital nephrogenic DI is caused by the arginine vasopressin receptor 2 (AVPR2) or aquaporin 2 (AQP2) gene mutation; the AVPR2 genetic mutation accounts for 90% of the cases. National health screening for infants and children was launched in 2007 in order to prevent accidents and promote public health in infants and children in Korea. The program has been widely used as a primary clinical service in Korea. We treated an infant with faltering growth and delayed development detected by the National health screening program, and diagnosed the problem as nephrogenic DI caused by a rare missense mutation of c.490T>C on the AVPR2 gene. This case can be a good educational nephrogenic DI with a rare AVPR2 mutation, which was well screened and traced by the national health screening program for infants and children in Korea.
