Hepatitis C virus (HCV) infection is present in a high proportion of patients with kidney transplantation. Compared with uninfected kidney transplant recipients, HCV infected kidney recipient have higher prevalence of liver disease and worse allograft survival after transplantation. Interferon monotherapy before transplantation is standard therapy for HCV-infected kidney transplant candidates. If HCV infection is discovered after transplantation, interferon monotherapy is considered due to the limited critical situation. However, in this patient, who was a kidney recipient, HCV infection was treated after kidney transplantation with peginterferon-α and rivabirin. As a result, the patient achieved sustained virologic response.

Primary cutaneous mucinous carcinoma (PCMC) is a rare low-grade malignant neoplasm derived from the eccrine glands. PCMC most commonly arises in the head and neck, with the eyelid being the most common site of origin. This case report describes a 51-year-old male with a painless, pigmented superficial nodular lesion over his right lower eyelid. The lesion was considered to be benign, and the initial treatment was simple excision with a 3-mm margin. However, histologic examination revealed the diagnosis of PCMC, and the patient underwent re-excision of the tumor site with an additional 3-mm margin from the initial scar. Histologic study of this second margin was free of any malignant cells. The patient experienced no postoperative complication or recurrence after 2 years. In our case, the skin lesion had benign morphologic findings and was strongly suspected to be a benign mass. Physicians should be aware of this tumor and be able to differentiate it from benign cystic or solid eyelid lesions.

BACKGROUND: Keloids are abnormal wound responses that are caused by hyperproliferative growth of connective tissue during the healing process. Recent research findings introduced the roles of reactive oxygen species (ROS) in the process of keloid formation. ROS induces oxidative stress and promotes the activities of oxidative damage-inducible genes. Aldo-keto reductase 1C3 (AKR1C3) prevents destructive ROS toxicity by detoxification of reactive carbonyl species. Thus, this study aimed to compare the expression of AKR1C3 in both normal and keloid skin in vivo. METHODS: Six specimens of normal skin and six specimens of keloid tissues from human subjects were used to evaluate the expression of AKR1C3 by immunofluorescent staining of tissues and western blotting. RESULTS: By western blotting, it was confirmed that the amount of AKR1C3 protein is significantly reduced in keloid tissues compared to normal tissues. Weak expression of AKR1C3 was also found in keloid tissues by immunofluorescent staining. CONCLUSIONS: This study confirmed that the expression of AKR1C3 protein participates in ROS metabolism and plays a part in the downregulation of human keloid formation. To the best of our knowledge, this is the first work that reveals that AKR1C3 can affect the formation of keloids.

PURPOSE: In Korea, the entire population must enroll in the national health insurance system, and those who are classified as having a lower socioeconomic status are supported by the medical aid system. The aim of this study was to evaluate the association of the medical insurance status of gastric cancer patients with their survival after gastrectomy. MATERIALS AND METHODS: A total of 247 patients who underwent surgical treatment for gastric cancer between January 1999 and December 2010 at the Seoul Medical Center were evaluated. Based on their medical insurance status, the patients were classified into two groups: the national health insurance registered group (n=183), and the medical aid covered group (n=64). The survival rates were calculated using the Kaplan-Meier method. RESULTS: The median postoperative duration of hospitalization was longer in the medical aid covered group and postoperative morbidity and mortality were higher in the medical aid group than in the national health insurance registered group (P<0.05). The overall 5-year survival rate was 43.9% in the medical aid covered group and 64.3% in the national health insurance registered group (P=0.001). CONCLUSIONS: The medical insurance status reflects the socioeconomic status of a patient and can influence the overall survival of gastric cancer patients. A more sophisticated analysis of the difference in the survival time between gastric cancer patients based on their socioeconomic status is necessary.

PURPOSE: In treatment of facial bone fracture, occurred in children, we generally use wires, miniplate, absorbable plate or their combination. These foreign bodies can be palpable, and sometimes may cause infections, and need reoperation for removing. When bone fragments are multiple, small or thin, they are hard to handle and make accurate reduction of all fragments. In these cases, a biodegradable tissue adhesive, Histoacryl(R) (n-butyl-2-cyanoacrylate), can be used as fixation technique for small, multiple, and thin fracture fragments. METHODS: 3 years old and 6 years old children, who has comminuted fracture on frontal sinus, we used Histoacryl(R) for fixation of multiple bone fragments. After approaching by coronal incision, we pulled out all bone fragments and reconstructed bone fragments by Histoacryl(R) and fixed those on frontal sinus by absorbable plates. RESULTS: Photographs and 3-dimensional CT obtained preoperatively and postoperatively. And we compared them each other in terms of accuracy of reconstructed bony contour. We could reconstruct almost all bone fragments easily along 3-dimensional structure and get excellent aesthetic results. There was no complication such as infection. CONCLUSION: In treatment of comminuted facial bone fracture, occurred in children, Histoacryl(R) is an excellent method for accurate reconstruction in small and thin bone fragments which cannot be fixed by wire, miniplate or absorbable plate without complication.

PURPOSE: Schwannoma, a benign peripheral nerve tumor, is slow-growing, encapsulated neoplasm that originates from the Schwann cell of the nerve sheath. Schwannoma most frequently involves the major nerve. Schwannoma occurring in the superficial radial nerve rare. This is a report of our experience with schwannoma arising from the superficial radial nerve with neurologic symptom. METHODS: A 55-year-old woman presented with eight-month history of progressive numbness and paresthesia in dorsum of the thumb and index finger. Physical examination revealed a localized mass on the midforearm. Sonographic examination showed an ovoid, heterogenous, hypoechoic lesion, located eccentrically in related to the superficial radial nerve. The lesion was mobile in the transverse but not in the longitudinal axis of the nerve, which was thought to favour schwannoma rather than neurofibroma. At operation, a 20 x 15 mm ovoid, yellowish grey mass was seen arising from the superficial radial nerve. The tumor present as eccentric masses over which the nerve fibers are splayed. Using operating microscope, the tumor was removed, preserving the surrounding nerve. RESULTS: Histology confirmed that the mass was a benign schwannoma. There were no postoperative complications. After two months the patient had no clinically demonstrable sensory deficit. CONCLUSION: An unsusual case of a schwannoma of the superficial radial nerve is presented. In case with neurologic symptom, prompt surgical decompression must be made to prevent further nerve damage and to restore nerve function early.

BACKGROUND: The active metabolite (1, 25-dihydroxycholecalciferol) of vitamin D (25-hydroxycholecalciferol) leads to activation of macrophages and deficiency of vitamin D seems to be involved in the risk of tuberculosis. The effects of vitamin D are exerted by interaction with the vitamin D receptor (VDR) and may be influenced by polymorphism in the VDR gene. In this study, variation in the VDR gene was investigated in Korean population with tuberculosis. METHODS: We typed three VDR polymorphisms of restriction endonuclease sites for TaqI, BsmI and FokI in 155 patients with tuberculosis and 105 healthy volunteers. RESULTS: The frequencies of FokI genotypes determined from TB patients were 29.13% for FF, 56.31% for Ff, and 14.56% for ff. We observed 1.4-fold increased prevalence of the Ff genotype in TB patients compared with normal healthy groups (p=0.0857). However, there was no significant association between the genotype groups, TB patient and normal control, for FokI polymorphism. There was also no significant association between VDR gene and tuberculosis in another polymorphism (BsmI and TaqI). CONCLUSION: Three polymorphisms (TaqI, BsmI and FokI) in the VDR gene do not appear to be responsible for host susceptibility to human tuberculosis in Korean population.

PURPOSE: Schwannoma is a slow-growing, encapsulated benign peripheral nerve tumor that originates from the Schwann cell of the nerve sheath. Schwannoma most frequently involves the major nerve. Schwannoma of the foot is rare. This is a report of our experience with a small, deep-seated, and non-palpable schwannoma occurring in the foot. METHODS: A 42-year-old woman presented with the plantar pain of the right foot during 2 years. Physical examination did not identified a palpable mass. She made a clinical diagnosis of plantar fasciitis and was conservatively treated 2 years ago. Since her plantar foot pain was aggravated, she was recently visited again. For the evaluation of her plantar foot pain, sonographic examination of the whole right foot was performed, and it revealed a small hypoechoic hetergenous, deep-seated mass beneath the plantar aponeurosis. At operation, a 0.7x0.6x0.4cm sized, ovoid, yellowish grey mass was removed. RESULTS: Histology was confirmed that the mass was a benign schwannoma. There were no postoperative complications. CONCLUSION: Unsusual case of a schwannoma with the plantar foot pain during 2 years is presented. It should be recognized a small, deep-seated, non-palpable schwannoma as a possible cause of plantar foot pain.
