Korean Journal of Veterinary Research 2019;59(1):51-54
Pulmonary masses were observed in the thoracic cavity of a 9-year-old female Korean native cattle (Hanwoo) encountered at a Jeju, Korea slaughterhouse. Grossly, the thoracic cavity was filled with pulmonary masses. Histologically, the neoplastic masses were composed of many abnormal papillary structures lined by single to double columnar neoplastic cells and formed arborizing fronds supported by significant fibrovascular stroma. The neoplastic cells showed strong destructive and infiltrative growth to adjacent tissues and were strongly positive for pan-cytokeratin (CK), CK 7 and sporadically positive for CK MNF116. The masses in the female Hanwoo were diagnosed as a papillary pattern of pulmonary adenocarcinoma.

The term halo congenital nevus is a condition in which halo formation is associated with congenital melanocytic nevus. The regression of congenital melanocytic nevi is usually accompanied by the halo phenomenon and this is considered to be a rare event, although this may be underestimated. We describe here a 9-year-old boy with verrucous congenital nevus surrounded by a depigmented halo on the right upper arm. Histologically, the nevus lesion revealed a dense lymphocytic infiltration in the upper dermis intermingled with some remnants of nevus cell nests. Most of the infiltrating cells were CD8+ T lymphocytes. At the edge of the lesion, corresponding to the area of the halo, neither melanocytes nor melanin were found in any significant amounts.

BACKGROUND: Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disease of an unknown etiology, and this is characterized by spiking fever, evanescent rash, arthritis and multiorgan involvement. OBJECTIVE: This study was conducted to better understand the clinical characteristics of patients with AOSD, and especially the cutaneous features. METHODS: We reviewed the medical records and cutaneous findings of 21 patients who were diagnosed with AOSD at our hospital from 2003 to 2009. The diagnosis of AOSD was based on the criteria proposed by Yamaguchi et al. RESULTS: Eighteen (86%) out of the 21 patients were women, and the age of onset ranged from 18 to 55 years. Fever occurred in 21 (100%) patients, skin rash in 20 (95%), arthralgia in 18 (86%), sore throat in 10 (48%) and lymphadenopathy in 7 (33%). The cutaneous features were as follows: typical maculopapular eruption (70%), urticaria (10%), petechia and purpura (10%), persistent plaques and linear pigmentation (5%) and acne-like lesions (5%). The most common sites of skin lesion were the trunk (80%) and thighs (80%). The histopathologic findings of 9 patients showed non-specific chronic inflammation with a perivascular mononuclear preponderance in 6 patients, and the others were consistent with urticaria or leukocytoclastic vasculitis. CONCLUSION: The various cutaneous features of this study suggest that dermatologists should consider AOSD in any patient with cutaneous eruption associated with fever and arthralgia.

Drowning is the second most common cause of accidental death of children in Korea. But the study of near-drowning is very rare in Korea. The purpose of our study is to determine the factors that may influence survival on the basis of submersion time, consciousness state upon admission to hospital, the kinds of water, laboratory findings and neurological outcomes. The survey was performed by a retrospective cohort study on 28 near drowning victims of less than 15 years of age who were admitted to the emergency room in the Chosun University Hospital between May 1988 & May 1997. The results were as follows 1) Sex distribution was 22 males and 6 females. 2) Submersion time was (5 minutes in 9 cases, 5-9 minutes in 6 cases,10-14 minutes in 5 cases,15-19 minutes in 3 cases, > or =20 minutes in 5 cases. 3) Comatose patients upon arrival were 6/7 cases in the death group(86%) and 2/21 cases in the improved group(10%). they had unfavorable outcomes(P<0.05). 4) The first pH value was mean 7.02)0.12 in the death group and mean 7.31 +/-0.13 in the improved group. there was a statistically significant difference between the death and the improved group(P<0.05). 5) The patients who had increased blood glucose concentration were all 7 cases in the death group and 12/22 cases in the improved group(54%). The mean blood glucose concentration was mean 424.7235.6mg/dl in the death group and mean 140.182.7mg/dl in the improved group. There was a statistically significant difference between the death and the improved group(P<0.05). 6) The patients who had pulmonary edema upon arrival were all 7 cases in the death group and 1/21 cases in the improved group(18%). They had unfavorable outcomes(P<0.05). 7) The patients who had been submerged more than 15 minutes were all 7 cases in the death group and 6/21 cases in the improved group(5%). They had unfavorable outcomes(P<0.05). We conclude that pediatric victims of near-drowning can be assigned to high or low likelihoods of unfavorable outcomes with the use of five variables, comatose mentation upon arrival, decreased initial blood pH, increased initial blood glucose concentration, pulmonary edema, and maximum submersion time estimated longer than fifteen minutes. This prediction rule may be useful if it can be validated in another cohort.

A 45-year-old female with psychosis complained urological symptom of urinary incontinence and voiding difficulty with abdominal pains and expansion during her psychiatric hospitalization and suddenly collapsed at the 14th day of the admission. At autopsy, the urinary bladder showed a focal perforation and the abdominal cavity was filled with massive urinary ascites. The both lower lobes and the right upper lobe of the lung were accompanied by atelectasis. The death mechanism of this case could be explained that an increased abdominal pressure produced by massive uroperitoneum with spontaneous bladder rupture led to respiratory failure. The so-called abdominal compartment syndrome was manifested by massive uroperitoneum and caused a death. This would be the first forensic medical case that an undiagnosed spontaneous bladder rupture resulted in death of a psychiatric illness patient.

In order to investigate the feasibility of a modified tension band combined with anti-gliding loop augmentation technique for the treatment of comminuted patellar fracture, 21 patients with comminuted patellar fracture were enrolled in this study. After the modified tension band wiring of patellar fracture, a cerclage wire was passed around the patella. Anti-gliding loops were made on the bending sites of Kirshner-wires. A knot was tied using both ends of the anti-gliding loops, and the cerclage wire was tightened using proximal knots. Bone union was achieved at 4.5+/-1.5 months postoperatively without nonunion. The Lysholm score was 87.1+/-2.8, and the range of motion of the knee was 2.1degrees+/-3.4degrees to 132.2degrees+/-6.5degrees at the last follow-up. The modified tension band combined with anti-gliding loop augmentation technique might be considered an alternative modification of modified tension band wiring for the treatment of comminuted patellar fracture.

Salmonella (S.) Typhimurium is highly contagious, and its infection may rapidly spread within pig populations of herd. According to the survey (1,191 pigs) from 2003 to 2012, 155 pigs (13.0%) were diagnosed as salmonellosis in Jeju. Major porcine salmonellosis cases (88.4%) were concentrated in 4- to 12-week-old weaned pigs, but 6 pigs (3.9%) under 4 weeks old were also diagnosed. Based on the histopathologic examinations, ulcerative enteritis (63.9%) in the large intestine and/or paratyphoid nodules formation (57.4%) in the liver were most prevalent lesions in porcine salmonellosis. Single infection of S. Typhimurium and mixed infection with more than 2 pathogens were detected in 38 (24.5%) and 117 (75.5%) in pigs, respectively. Co-infections of Porcine reproductive and respiratory syndrome virus and Porcine circovirus type 2 were very common in porcine salmonellosis in Jeju and detected in 84 (54.2%) and 59 (38.1%) pigs, respectively. Based on the serotyping tests using 41 bacterial isolates, S. Typhimurium and S. Rissen were confirmed in 39 (95.1%) and 2 (4.9%) cases, respectively.

PURPOSE: Tetanus is difficult for emergency physician to diagnosis at an early stage because of its low incidence and atypical initial clinical features. Therefore, we reviewed the clinical features of 54 tetanus cases and attempted to identify factors associated with prognosis in order to improve early diagnosis and treatment. METHODS: We carried out a retrospective chart review of 54 adult tetanus patients who presented to the ED of Chonnam National University Hospital between January 1996 and December 2005. We collected information on demographics, SAPS II score, clinical feature, course of infection and prognosis. We divided the patients to two groups according to the survival and compared their data statistically. RESULTS: Fifty four patients, 33 men and 21 women, were included in the study. The mean age was 50.97+/-15.95. The most common initial diagnosis in ED were electrolyte imbalance (n=15), neck and facial dystonia (n=9). The mean incubation period was 10.27+/-6.47 days. The initial SPAS II score 17.29+/-8.45 and the Wood score was 3.12 +/-1.47. Most commonly symptom was dyspnea and dysarthria. Twenty one patients were supported by mechanical ventilation, and the duration of mechanical ventilation was 5.92+/-4.52 days. On multivariate logistic regression analysis, four variables were found to be associated with the prognosis: incubation period, Wood score, Time interval from initial symptom to mechanical ventilation, initial SAPS II. CONCLUSION: Four variables correlated well with the prognosis: Incubation period, Wood score, Time interval from initial symptom to mechanical ventilation, initial SAPS II score.
