An aneurysm occurs in association with trauma, atherosclerosis, infection and congenital diseases. Among these, the traumatic arterial aneurysms developed from blunt trauma, crushing injury, perforation, and lacerations of vessels. Generally, most traumatic arterial aneurysms are false type, so called pseudoaneurysm. A pseudoaneurysm occurs by incomplete laceration of the vessel wall or partial division of the vessel. The vascular injury will make hematoma and fibrosis of neighboring tissues. After two to eight weeks post-trauma, the organized hematoma is liquefied and the fibrous tissue acts as an aneurysmal sac. We have experienced a case of dorsalis pedis artery pseudoaneurysm associated with arterial cannulation. So, we report a case of traumatic pseudoaneurysm with a review of literature.

BACKGROUND: Peak expiratory flow (PEF) provides a simple, quantitative, and reproducible measure of the existence and severity of airflow obstructions. Peak flow meters are designed to monitor the condition asthma patients. There are many reports showing the normal predicted value of PEF in other countries. studies on healthy Korean adults have been performed in a relatively small sample number and a lower limit for the normal value was not reported. therefore, an attempt to provide normal predictive PEF value with a lower limit was made. METHOD: The PEF(Mini-Wright peak Flow Meter) measurements and spirometry were done in 233 men and 631 woman without history of respiratory disease. all subjects were non-smokers with no respiratory symptoms. the normal predictive value and its lower limit were developed by multiple regression analysis. The result was compared with regression equations in other reports. RESULTS: The regression equation for the normal PEF predictive value(L/min) is 25.117+4.587×Age(year)-0.064×Age2+2.931×Height(cm) in men in men(R2=0.25), and 146.942-0.011×Age2+1.795×Height(cm)+0.836×Weight (kg) in women(R2=0.21). The regression equation for the lower limit of this value (L/min) is 25.117+4.587×Age(year)-0.064×Age2+1.936×Height (cm) in men, and 146.942-0.011×Age2+1.232× Height (cm)+0.481×Weight (kg) in women. The residuals were normally distributed. The PEF in Korean males was similar to those reported in British and Japanese subjects. The PEF in Korean females was similar to that in British subjects, But higher than the PEF in Japanese subjects. The lower limit of normal value was 71% of normal predictive PEF value in men and 76% in women. CONCLUSION: The normal predictive PEF value and its lower limit was measured from 233 male and 631 female asymptomatic, lifelong non-smoking participants. The normal predictive value was different from those of other studies on Korean subjects. Therefore, further studies are required.

In this experiment, pregnant Sprague-Dawley rats were treated with 100mg/kg of alltrans retinoic acid at 10th day of gestation. Pregnant rats were sacrificed at gestation day 14, 15, 16 and 18. Fetuses were delivered, and palatal processes were dissected. The specimens were prepared with fibronectin immunohistochemical stain, and mesenchymal changes were observed with electron microscope. The results were as follows. 1. In the findings fo fibronectin immunohistochemial stain, a part of the mesenchyme of the palatine process of the control group showed weak positive reaction at 14th gestation day, and the reactivity increased progressively by each day. In retinoic acid treated group, the positive reaction was trace at 14th day of gestation, and the reactivity increased progressively, but it was weaker than that of the control group. 2. Examination under transmission electron microscopy revealed well-developed rough endoplasmic reticulum, Goigi apparatus, mitochondrias which were found at the palatine process of the control group. In the retinoic acid treated group, at 16th and 18th day of gestation, the mesenchymal cells of the elevated palatine process had fragmented, sacculated rough endoplasmic reticulums, their mitochondrias were swollen and dissolved, In all cases with retinoic acid treated group, mitotic cells at various stages were more frequently found than in control group. In conclusion, the retinoic acid induces alterations of the intracytoplasmic organells. This finding suggests that retinoic acid is ditectly cytotoxic to mesenchymal cells. Positive fibronectin reaction was demonstrated before palatal elevation at th 15th day of gestation. Therefore, it could be postulated that mesenchymal cells synthesize and release the fibronectin. In the retinoic acid treated group, fibronectin showed positive reaction before and after palatal elevation, and it suggests that fibronectin would be involved in palatal elevation.

Hypospadias can be repaired in the majority cases in 1-stage with a high success rate. We reviewed clinical experience of 50 patients who underwent primary hypospadias repair by 1 surgeon using 1-stage repairs except 3 cases in a 30-month period. The results were 1). The half of patients were younger than 5 years (48%). 2). A total of 34 cases (68.0%) had an associated ventral curvature. The dorsal tunica albuginea plication to correct intrinsic curvature was done in 21 cases (61.8%) and dividing the urethral plate in only 3 cases (8.8%). 3). Associated anomalies were cryptorchidism in 7, hydrocele in 3 and severe penoscrotal transposition in 8 cases. 4). 19 cases of anterior hypospadias were repaired by meatoplasty using Heineke-Mikulicz tissue rearrangement (9 cases), MAGPI (3 cases), pyramid procedure (4 cases), Mathieu urethroplasty (2 cases) and onlay island flap (1 case). Of the 31 cases of middle and posterior hypospadias onlay island flap repair was performed in 24 cases (77.4%). 5). The success rates in anterior, middle and posterior hypospadias were 94.7, 64.7 and 42.9%, respectively. The overall success rate was 70%. 6). The most commonly used procedure was onlay island flap urethroplasty. Only 14 of 25 cases (56.0%) were successful with this method but the last 8 cases were repaired with no complications. 7). The most common complications were urethrocutaneous fistula (11 cases) and meatal retraction (3 cases). The complications were managed by rotational advancement flap (11 cases), meatal based flap (2 cases) and urethral advancement (1 case) and the success rate was 73.3%. In conclusion, to achieve more satisfactory results the choice of operation depends on the configuration of either glans or meatus, presence or absence of chordee and status of ventral penile skin in anterior hypospadias. Although the 2-stage repair remains a safe and reliable alternatives for severe hypospadias 1-stage repair was more useful except severe hypospadias combined with penoscrotal transposition."

OBJECTIVES: Investigations into foodborne illness, potentially caused by Kudoa septempunctata, has been ongoing in Korea since 2015. However, epidemiological analysis reporting and positive K septempunctata detection in feces in Korea has been limited. The aim of this study was to provide epidemiologic data analysis of possible food poisoning caused by K septempunctata in Korea. METHODS: This study reviewed 16 Kudoa outbreak investigation reports, including suspected cases between 2015 and 2016 in Gyeonggi province, Korea. Suspected Kudoa foodborne illness outbreak was defined as “evidence of K septempunctata in at least one sample.” The time and place of outbreak, patient symptoms and Kudoa (+) detection rate in feces was analyzed. RESULTS: Kudoa foodborne illness outbreaks occurred in most patients in August (22.6%) and in most outbreaks in April (25%). The attack rate was 53.9% and the average attack rate in patients who had consumed olive flounder was 64.7%. The average incubation period was 4.3 hours per outbreak. Diarrhea was the most common symptom which was reported by 91.5% patients. The Kudoa (+) detection rate in feces was 69.2% of cases. CONCLUSION: Monthly distribution of Kudoa foodborne illness was different from previous studies. The Kudoa (+) detection rate in feces decreased rapidly between 25.5 and 28.5 hours of the time interval from food intake to epidemiologic survey. To identify effective period of time of investigation, we believe additional study with extended number of cases is necessary.

Objectives: The number of cases of hepatitis A virus (HAV) infections has sharply increased in Korea, especially among young adults. In this study, an HAV outbreak in a facility for disabled people was investigated, and we found epidemiological differences both between 2 different generations and between generally abled and disabled groups. Methods: We analyzed the incubation period and attack rate of an HAV outbreak and investigated the prevalence of HAV antibodies among the staff and residents of a facility for the disabled. We performed a retrospective cohort study during the HAV outbreak, which lasted from February 8 to 25, 2019, including examinations of HAV antibody tests and post-exposure HAV vaccination for the staff or residents of the facility. Results: There were 9 confirmed cases in 2 staff members and 7 residents. Among 53 people (30 staff and 23 residents), except for the 9 confirmed cases and 1 staff member with a known history of HAV infection, HAV seroprevalence was seen in 16.7% of the staff under 40 years of age and 95.2% of those over 40 years of age, while the corresponding rates in the residents were 0.0% and 58.8%, respectively. Conclusions This result implies that it is necessary to prioritize HAV vaccination for vulnerable groups and workers of residential care facilities.
