Hereditary anhidrotic ectodermal Dysplasia is a congenital disease displaying characteristics of anhidrosis, hypotrichosis and dental defect which are caused by developmental anomaly of ectodermal epidermis and its appendages. We experienced two cases of hereditary anhidrotic ectodermal dysplasia in two-year and four-month old twin brothers. These patients suffered from intermittent high fever early in life which brought them to our clinical attention. However the diagnosis of anhidrotic ectodermal dysplasia was not suspected by means physicians who cared the patients previously. The diagnosis was made on the basis of clinical features, and confirmed by starch iodine sweat test and skin biopsy on the palm and axilla. We report the two cases in a twin brothers with brief review of related literatures.

Pena-Shokeir I syndrome is a multiple malformation syndrome displaying characteristics of camptodactyly, multiple ankylosis, severe muscle weakness, facial anomalies (low set ears, hypertelorism, depressed tip of nose), polyhydramnios, fetal growth retardation & pulmonary hypoplasia which are inherited by autosomal recessive trait. We experienced 1 case of Pena-Shokeir I syndrome in a neonate (41 weeks, 2.08Kg). This patient suffered from dyspnea. Respiratory destress was not relieved after ventilatory care. He died aged 10 days. We report this case with brief review of literature.

Objective: To compare preventable trauma death rates (PTDRs) in patients with traumatic brain injury before and after the establishment of a regional trauma center (RTC) at a single center. Methods: Our institution established an RTC in 2014. A total of 709 patients were enrolled from January 2011 to December 2013 (before RTC) and 672 from January 2019 to December 2021 (after RTC). The revised trauma score, injury severity score, and trauma and injury severity score (TRISS) were evaluated. Definitive preventable (DP), possibly preventable (PP), and non-preventable deaths were defined as TRISS >0.5, TRISS 0.25–0.5, and TRISS <0.25, respectively. PTDR was the proportion of deaths from DP+PP out of all deaths, and the preventable major trauma death rate (PMTDR) was the proportion of deaths from DP+PP out of all DP+PP. Results: The overall mortality rates before and after the establishment of RTC were 20.3 and 13.1%, respectively. PTDR was lower after the establishment of RTC than before (90.3% vs.79.5%). The PMTDR was also lower after the establishment of RTC than before (18.8% vs.9.7%). The ratio of direct hospital visits was higher in patients before the establishment of RTC than in those after (74.9% vs. 61.3%, p<0.001). Conclusion Establishing the RTC reduced PTDRs. Additional studies on factors associated with PTDR reduction are required.

BACKGROUND AND OBJECTIVES : Ageotrophic nystagmus in the horizontal canal BPPV has been explained as a result of cupulolithiasis theory, and has been reported to have the less therapeutic response to conservative rehabilitations than the other type BPPV . Though methods to detach the debris with vibrator have been introduced, the effect has been questioned and it's not physiologic. MATERIALS AND METHOD : We introduce a new head shaking-forced prolonged position method as a more convenient method, and report typical 2 cases of ageotrophic horizontal canal BPPV managed with it and analyzed results of 25 cases all told. RESULTS AND CONCLUSION : The average number of rehabilitation was less than two, and loss of direction changing positional nystagmus could be observed immediately after rehabilitation.

PURPOSE: The aim of this study was to evaluate the effectiveness and indication of radiofrequency ablation(RFA) using renal VX2 tumors by implantation of VX2 tumor cells under the renal capsule in rabbits. MATERIALS AND METHODS: Ten rabbits were injected with 30-40microliter VX2 tumor cells(1.2x10(7) viable cells/ml) under the renal capsule of the right kidney by right subcostal incision. On the 14th day after the tumor cells were implanted, we checked for the development of renal tumors, and the sizes and shapes(exophytic or central) of the tumors by the use of computed tomography. We performed RFA in the renal VX2 tumors with a 17G StarBurst electrode through kidney exposure. After the first and third day following RFA, renal function was checked. On the third day, we performed CT and harvested the kidneys for gross and microscopic evaluation. RESULTS: We confirmed the development of renal VX2 tumors in nine cases. Tumor shapes were exophytic in seven cases and central in two cases; the mean size of the tumors was 2.1 cm(range, 1.1-3.8cm). In all tumors, RFA was performed. From the use of enhanced CT after RFA on the third day, all of the lesions treated with RFA showed no enhancement. From the pathological findings, coagulative necroses were seen on all of the lesions treated with RFA. The necrotized tumor size after RFA was not different statistically as measured by CT and a pathological examination (p=0.833) CONCLUSIONS:: In centrally located renal tumors, we experienced thermal injury in pelvocalyceal systems. RFA is an effective method for nephron sparing surgery as the tumor cells completely disappear and there is preserved renal function and the procedure is easy to apply. We suggest that the RFA method for exophytic renal tumors is more effective than other procedures.

In May 2011, five consecutive gastroenteritis outbreaks were reported at schools in Gyeonggi-do. Epidemiological inspection revealed that one food manufacture company provided 'Kimchi', a traditional Korean side-dish, to these five schools for catering services. Fecal specimens were collected from students and food-handlers to determine causative viral agents. Norovirus genogroup GI was detected from 58 samples out of total 239 specimens by reverse-transcription (RT)-PCR, whereas norovirus GII was found only from one sample. Epidemiological studies also revealed that the Kimchi was processed using groundwater in the food manufacture company. Four groundwater samples were collected from the company and around the area. Norovirus GI was detected from three samples. To determine the norovirus genotypes of positive specimens from clinical and groundwater samples, sequencing and phylogenetic analyses were performed. The genogroup GI from 58 clinical and three groundwater samples and the GII from one food-handler were identified as norovirus GI.3 and GII.18, respectively. Sequence alignment analysis with norovirus GI.3 isolates revealed that identity between clinical and groundwater samples was over than 99.1% in nucleotide level. In conclusion, norovirus GI.3-contaminated groundwater caused the gastroenteritis outbreaks of five schools, through Kimchi. This molecular epidemiological study was an important report in Korea that clearly identified all transmission routes of norovirus GI.3.
