PURPOSE: Pilomatrixoma is a benign, usually asymptomatic tumor. It presents clinically as a solitary superficial subcutaneous nodule measuring between 0.5 cm and 5 cm in diameter on the head or upper extremeties and has not been reported after skin graft. The objective of this article is to report our experience in treating pilomatrixoma which occurred after split thickness skin graft on the lower extremity. METHODS: A 56-year-old female was treated in August 2005 with a 0.5 X 0.5 cm firm subcutaneous nodule at recipient site of split thickness skin graft on the left medial thigh. The tumor was successfully removed by complete excision and histologic examination was followed. RESULTS: The diagnosis was pilomatrixoma which was characterized by a dual population of proliferating basophilic cells and diagnostic shadow cells. CONCLUSION: The tumor was successfully treated by complete resection. The authors report this very rare case of pilomatrixoma which occurred at recipient site of split thickness skin graft.

Pelvic fistulas may result from obstetric complications, inflammatory bowel disease, pelvic malignancy, pelvic radiation therapy, pelvic surgery, or other traumatic causes, and their symptoms may be distressing. In our experience, various types of pelvic fistulas are identified after pelvic disease or pelvic surgery. Because of its close proximity, the majority of such fistulas occur in the pelvic cavity and include the vesicovaginal, vesicouterine, vesicoenteric, ureterovaginal, ureteroenteric and enterovaginal type. The purpose of this article is to illustrate the spectrum of imaging features of pelvic fistulas.

BACKGROUND: Phagocytosis is probably the first step for mycobacteria to be virulent in host because virulent strains are more readily phagocytosed by macrophage than attenuated strains. According 13 the traditional concept, multi-drug resistant strains have been regarded as less virulent. However, this concept has been challenged, since recent studies(reported) showed that the degree of virulence and drug-resistance is not related. The purpose of this study is to evaluate whether the phagocytic activity of M. tuberculosis by peripheral blood mononuclear cells(PBMC) is different according to drug-resistance or host factor. To evaluate this, we estimated the difference of phagocytic activity of drug-resistant and drug-sensitive M. tuberculosis and also estimated the phagocytic activity of PBMC from intractable tuberculosis patients and healthy controls. METHODS: PBMC from ten intractable tuberculosis patients and twelve healthy control and three different strains of heat-killed M. tuberculosis, ie, ADS(all drug sensitive), MDR(multi-drug resistant), and ADR(all drug resistant) were used. After incubation of various strains of M. tuberculosis with PBMC, the phagocytic activity was evaluated by estimating proportion of PBMC which have phagocytosed M. tuberculosis. RESULTS: Drug-resistant strains of M. tuberculosis were phagocylosed easily than drug sensitive strains(Percentage of PBMC phagocytosed M. tuberculosis in healthy control : ADS : 32.3α2.9%, ADR : 49.6α3.4%, p=0.0022, Percentage of PBMC phagocytosed M. tuberculosis in intractable tuberculosis patients : ADS : 34.9α3.6%, ADR : 50.7α4.5%), p=0.0069). However, there was no difference in phagocytic activity of PBMC from healthy control and intractable tuberculosis patients. CONCLUSION: Drug-resistant strains of M. tuberculosis were phagocytosed easily than drug sensitive strains and host factors does not seems to influence the phagocytosis of M. tuberculosis.

BACKGROUND: Some of the deficiencies in anterior pituitary function identified in subjects with macroadenomas appear to represent irrevemible necrosis of normal pituitary cells, and in addition reversible damage to viable glandular tissue and/or incomplete interruption of local circulation by compression of pituitary stalk may also contribute significantly to hypopituitarism. So anterior pituitary function may actually improve in some patients undergoing successful tumor resection or reduction in tumor size. Although direct comparisons of pituitary function among the various pituitary tumors are not presently available it was reported that there is some difference in the degree of pituitary impairment between patients with nonfunctioning macroadenoma(NFMA) and those with GH-secreting macroadenoma(GHMA).In this study, to investigate the difference in the degree of hypopituitarism we compared anterior pituitary function in subjects with NFMA to that in patients with GHMA. METHODS: In this retrospective study, preoperative and postoperative anterior pituitary function was assessed by clinical findings, basal hormone levels and/or combined pituitary stimulation test in 29 subjects with NFMA and in 24 subjects with GHMA. RESULTS: 1. There was no difference in age, sex, tumor size distribution between the two groups. 2. Preoperatively, NFMA patients had a higher prevalence of secondary hypothyroidism(34% vs. 5%; p(0.02) compared to subjects with GHMA. Patients with NFMA also had a higher prevalence of more severe pituitary failure compared with acromegalic patients; 48% of the patients in this group had more than one pituitary hormone axis impaired compared to 17% in the acromegalic group(p0.03). 3. Postoperatively, NFMA patients also had a higher prevalence of secondary hypoadrenalism (52% vs. 11%; p 0.01) compared with acromegalic patients. Additionally, the prevalence who had more than one pituitary hormone axis impaired was still greater in NFMA patients than in the acromegalic group(57% vs. 22%; p=0.054). 4. No correlation was found between the severity of pituitary failure and tumor size or extension in both groups before and after surgery. CONCLUSION: These findings suggest that anterior pituitary function is relatively better preserved in patients with GHMA than those with NFMA and that this difference is independent of tumor size and extension. The mechanism underlying the lower rate of hypopituitarism in acromegalics with macroadenoma remains to be elucidated.

This study was conducted to evaluate prevalence of intestinal helminthic infections and skin tests and Paragonimus and Clonorchis in tuberculosis(TB) patients in Korea. Stool examinations by formalin-ether technique and intradermal tests were carried out in 2 areas; Masan TB hospital and Kong-Ju TB hospital. The positive rate of intestinal helminths of any kind was 51.7 percent among 329 patients in Masan hospital, but 18.1 percent among 215 patients in Kong-Ju hospital. The infection rates of Trichocephalus trichiurus and Clonorchis sinensis were 20.7 percent and 17.6 percent respectively in Masan hospital patients, but the infection rates of T. trichiurus and C. sinensis were 6.5 percent and 6.0 percent respectively in Kong-Ju hospital patients. In skin tests, positive reactions to Paragonimus and Clonorchis antigens were 22.0 percent and 37.6 percent respectively in Masan hospital patients. On the contrary, Kong-Ju hospital patients showed the positive rates of 15.2 percent for Paragonimus and 27.2 percent for Clonorchis respectively.

Homeostasis of multicellular organism is controlled by proliferation and differentiation of cells as well as by cell death. The defects in programmed cell death contribute to the pathogenesis of rheumatoid arthritis (RA) and systemic lupus erythematous. RA is considered to be a proliferating disorder of synovial tissue which is accompanied by inflammatory cell infiltration and bone erosion. The aim of the study was to find whether potent inducers of apoptosis could be induced apoptosis in RA synovial cells. We examined the effects of drugs, such as dexamethasone, methotrexate, hydrogen peroxide, and ceramide on induction of apoptosis in cultured RA synovial cells. Used drugs did not induced apoptosis in RA synovial cells. Finally Fas antigen-mediated apoptosis of RA synovial cells was investigated by the addition of anti-Fas antibody. To examine the ICE (interleukin-1p-convertase; caspase-1) expression in synovial cells, RT-PCR of caspase-1 gene was performed. In synovial cells of RA, Fas induces that caspase-1 activation cause apoptosis.

Joubert syndrome first described by Joubert et al. in 1969 is a very rare congenital disorder, characterized by episodic hyperpnea, abnormal eye movement, hypotonia, ataxia, and mental retardation. This syndrome generally represents as autosomal recessive inheritance and main neuropathological finding is agenesis or aplasia of the cerebellar vermis. This patient represents significant generalized muscle hypotonia which is not affected by any other tone-modifying maneuvers. And so there is no significant neuromotor improvement with neurodevelopmental treatment such as Bobath method, Vojta method, or proprioceptive nerve facilitation technique and so on. We report the Joubert syndrome showing typical features with delayed development.

Pudendal nerve entrapment syndrome is an unusual cause of chronic pelvic pain. We experienced a case of pudendal neuralgia associated with a ganglion cyst. A 60-year-old male patient with a tingling sensation and burning pain in the right buttock and perineal area visited our outpatient rehabilitation center. Pelvis magnetic resonance imaging showed the presence of multiple ganglion cysts around the right ischial spine and sacrospinous ligament, and the pudendal nerve and vessel bundle were located between the ischial spine and ganglion cyst at the entrance of Alcock's canal. We aspirated the lesions under ultrasound guidance, and consequently his symptoms subsided during a 6-month follow-up. This is the first report of pudendal neuralgia caused by compression from a ganglion cyst around the sacrospinous ligament.

Vesical dome tumors are classified, according to their origin, as either vesical or urachal. A case of vesical dome tumor was diagnosed as an urachal carcinoma preoperatively because CT scan and cystoscopic findings were suitable to the diagnostic criteria of urachal carcinoma, but the transurethral biopsy result was transitional cell carcinoma (TCC). The final histopathologic report after extended partial cystectomy revealed that the tumor was originated from vesical mucosa and an intact urachal remnant was found around the resected mass. In a tumor situated on the midline of bladder dome, a transurethral biopsy before curative operation is essential.
