Adenocarcinoma metastatic to the skin usually originates in the lung, breast, large intestine or ovary. Cutaneous metastatic tumors from rectum or colon tend to appear in the abdominal or perineal area, but rarely appear in the perianal and genital skin. A 53-year-old female presented multiple nodules in and near the surgical scars of inguinal, pubie, vulvar, perianal areas and normal skin of left thigh two months after surgical removal of rectal adenocarcinoma. Biopsy specimens from the nodules of the perianal area and left thigh showed adenocarcinoma of well differentiated atruetures like the primary rectal carcinoma.

PURPOSE: To compare the functional and radiological outcomes of volar plating to that of external fixation for treating unstable osteoporotic distal radius fracture. MATERIALS AND METHODS: From March 2006 to March 2008, 36 patients with osteoporosis over 60-year old were selected for this study. They were divided into two groups; group I (open reduction and internal fixation with volar fixed angle plate) and group II (closed reduction and external fixation). Clinical outcomes and radiologic outcomes were evaluated. RESULTS: There was no statistical difference between group I and group II in range of motion and DASH score, BMD score. However, the grip strength and PRWE score were found to be higher in group II (p<0.05). In radiologic evaluation, group I showed higher radial inclination, volar tilting angle (p<0.05). CONCLUSION: Internal fixation using Volar-fixed Angle Plate seems to give more stable fixation for distal articular fragments compared to external fixation. it could allow early postoperative exercise and could result in low incidence of postoperative complication such as pin track infections and joint stiffness. Therefore, the internal fixation could be more desirable treatment method to manage unstable distal radius fracture.

The aim of this study was to validate a new paper and pencil test battery to diagnose minimal hepatic encephalopathy (MHE) in Korea. A new paper and pencil test battery was composed of number connection test-A (NCT-A), number connection test-B (NCT-B), digit span test (DST), and symbol digit modality test (SDMT). The norm of the new test was based on 315 healthy individuals between the ages of 20 and 70 years old. Another 63 healthy subjects (n = 31) and cirrhosis patients (n = 32) were included as a validation cohort. All participants completed the new paper and pencil test, a critical flicker frequency (CFF) test and computerized cognitive function test (visual continuous performance test [CPT]). The scores on the NCT-A and NCT-B increased but those of DST and SDMT decreased according to age. Twelve of the cirrhotic patients (37.5%) were diagnosed with MHE based on the new paper and pencil test battery. The total score of the paper and pencil test battery showed good positive correlation with the CFF (r = 0.551, P < 0.001) and computerized cognitive function test. Also, this score was lower in patients with MHE compared to those without MHE (P < 0.001). Scores on the CFF (32.0 vs. 28.7 Hz, P = 0.028) and the computer base cognitive test decreased significantly in patients with MHE compared to those without MHE. Test-retest reliability was comparable. In conclusion, the new paper and pencil test battery including NCT-A, NCT-B, DST, and SDMT showed good correlation with neuropsychological tests. This new paper and pencil test battery could help to discriminate patients with impaired cognitive function in cirrhosis (registered at Clinical Research Information Service [CRIS], https://cris.nih.go.kr/cris, KCT0000955).

Purpose:
Recent development in perioperative treatment of resectable non–small cell lung cancer (NSCLC) have changed the landscape of early lung cancer management. The ADAURA trial has demonstrated the efficacy of adjuvant osimertinib treatment in resectable NSCLC patients; however, studies are required to show which subgroup of patients are at a high risk of relapse and require adjuvant epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor treatment. This study evaluated risk factors for postoperative relapse among patients who underwent complete resection.
Materials and Methods:
Data were obtained from the Korean Association for Lung Cancer Registry (KALC-R), a database created using a retrospective sampling survey by the Korean Central Cancer Registry (KCCR) and the Lung Cancer Registration Committee.
Results:
A total of 3,176 patients who underwent curative resection was evaluated. The mean observation time was approximately 35.4 months. Among stage I to IIIA NSCLC patients, the EGFR-mutant subgroup included 867 patients, and 75.2%, 11.2%, and 11.8% were classified as stage I, stage II, and stage III, respectively. Within the EGFR-mutant subgroup, 44 (5.1%) and 121 (14.0%) patients showed early and late recurrence, respectively. Multivariate analysis on association with postoperative relapse among the EGFR-mutant subgroup showed that age, pathologic N and TNM stages, pleural invasion status, and surgery type were independent significant factors.
Conclusion
Among the population that underwent complete resection for early NSCLC with EGFR mutation, patients with advanced stage, pleural invasion, or limited resection are more likely to show postoperative relapse.
