BACKGROUND: Dermatophytoses tend to have a poorer outcome in diabetic patients than in non-diabetic patients. Therefore, diabetic patients need to pay a closer attention to the prevention and treatment of dermatophytoses. The aim of this study was to determine the level of understanding of the dermatophytoses in diabetic patients and to clarify the factors associated with the level of understanding. METHODS: A questionnaire survey was carried out from June to July, 2005, targeting 200 patients who had visited two hospitals in Seoul for the management of diabetes. There were 163 respondents (response rate 50.9%). The degree of understanding was calculated by giving 1 point to each question, with a maximum of 12 points. RESULTS: The average degree of understanding of dermatophytoses was 6.68 points (SD 1.79). Younger age (P= 0.0002), high education level (P=0.0035), and high income (P=0.0013) were the factors related to a better understanding of dermatophytoses. The patients who had obtained the information on dermatophytoses from the websites, broadcasts, newspapers, or magazines showed higher recognition points than others (P=0.0377). The body mass index, the duration of diabetes, the complications associated with diabetes did not affect the understanding of dermatophytoses. CONCLUSION: There are many diabetes patients who do not know enough about dermatophytoses. Diabetes itself is not related to the level of understanding of dermatophytoses. However, diabetic patients who are older, have a lower level of education, and a low income will need to be informed about prevention and treatment of dermatophytoses.

Ehlers-Danlos syndrome (EDS) is an inherited disorder of collagen biosynthesis and structure, characterized by skin hyperextensibility, joint hypermobility, aberrant scars, and tissue friability. Besides the skin, skeleton (joint) and vessels, other organs such as the eyes and the intestine can be affected in this syndrome. Accordingly, interdisciplinary cooperation is necessary for a successful treatment. Three basic surgical problems are arising due to an EDS: decreased the strength of the tissue causes making the wound dehiscence, increased bleeding tendency due to the blood vessel fragility, and delayed wound healing period. Surgery patients with an EDS require an experienced surgeon in treating EDS patients; the treatment process requires careful tissue handling and a long postoperative care. A surgeon should also recognize whether the patient shows a resistance to local anesthetics and a high risk of hematoma formation. This report describes a patient with a wide open wound on the foot dorsum and delayed wound healing after the primary approximation of the wound margins.

Rhino-orbito-cerebral mucormycosis (ROCM) is an uncommon, acute, and aggressive fungal infection occurring in several immunocompromised states including poorly controlled diabetes. ROCM causes a very high residual morbidity and mortality due to the angioinvasion property of the fungus. Acromegaly is a chronic condition resulting from the excessive secretion of growth hormone, generally from pituitary adenoma. Although it has been demonstrated that acromegalic patients have an increased risk of neoplasm, gastric cancer with acromegaly is very rare. We experienced a case of pituitary mucormycosis in the diabetic patient with acromegaly and gastric cancer. The patient was treated successfully with subtotal gastrectomy for early gastric cancer, transsphenoidal surgery for pituitary adenoma, and a systemic application of amphotericin B for the mucormycosis.

TGF-beta1-induced glomerular mesangial cell (GMC) injury is a prominent characteristic of renal pathology in several kidney diseases, and a ternary protein complex consisting of PINCH-1, integrin-linked kinase (ILK) and alpha-parvin plays a pivotal role in the regulation of cell behavior such as cell proliferation and hypertrophy. We report here that PINCH-1-ILK-alpha-parvin (PIP) complex regulates the TGF-beta1-induced cell proliferation and hypertrophy in cultured rat GMCs. When GMCs were treated with TGF-beta1 for 1, 2 and 3 days, the PIP complex formation was up-regulated after 1 day, but it was down-regulated on day 2. Cell numbers were significantly elevated on day 2, but dramatically decreased on day 3. In contrast, a significant increase in cellular protein contents was observed 3 days after TGF-beta1-treatment. TGF-beta1 induced early increase of caspase-3 activity. In GMCs incubated with TGF-beta1 for 2 days, cytosolic expression of p27(Kip1) was dramatically reduced, but its nuclear expression was remarkably elevated. A significantly decreased expression of phospho-Akt (Ser 473) was observed in the cells treated with TGF-beta1 for 1 day. TGF-beta1 induced early increase of phospho-p27(Kip1) (Thr 157) expression with subsequent decrease, and similar responses to TGF-beta1 were observed in the p38 phosphorylation (Thr 180/Thr 182). Taken together, TGF-beta1 differently regulates the PIP complex formation of GMCs in an incubation period-dependant fashion. The TGF-beta1-induced up- and down-regulation of the PIP complex formation likely contributes to the pleiotropic effects of TGF-beta1 on mesangial cell proliferation and hypertrophy through cellular localization of p27(Kip1) and alteration of Akt and p38 phosphorylation. TGF-beta1-induced alteration of the PIP complex formation may be importantly implicated in the development and progression of glomerular failure shown in several kidney diseases.

Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is a rare subtype of primary cutaneous lymphoma with a favorable prognosis. Primary cutaneous CD30+ lymphoproliferative disorders, which include C-ALCL and lymphomatoid papulosis, are the second most common group of cutaneous T-cell lymphomas. C-ALCL is comprised of large cells with anaplastic, pleomorphic, or immunoblastic cytomorphology, and indeed, more than 75% of the tumor cells express the CD30 antigen. C-ALCL clinically presents with solitary or localized reddish-brown nodules or tumors, and sometimes indurated papules, and they may be with ulceration covering with dark eschar. Multifocal lesions are seen in 20% of the patients. Extracutaneous dissemination, which mainly involves the regional lymph nodes, occurs in 10% of patients. A 69-year-old man noticed a mild elevated cutaneous lesion containing central ulceration covering with brownish black necrotic tissue on the right lower lip, and the lesion was surgically removed. After the first operation, another skin lesion was developed and the histological examination confirmed the diagnosis, C-ALCL. Eight specimens were excised during the 7-month follow-up period. The patient started the treatment with low-dose oral methotrexate (15 mg/wk) and there was no recurrence for 11 months.

PURPOSE: We investigated the effect of chemoradiotherapy with PP2 and temozolomide (TMZ) on malignant glioma cells using clonogenic assays and in vivo brain tumor model. MATERIALS AND METHODS: The effect of PP2 on radiosensitivity of U251 and T98G cells was investigated using clonogenic assays. The expression of E-cadherin, matrix metalloproteinases 2 (MMP2), Ephrin type-A receptor 2 (EphA2), and vascular endothelial growth factor (VEGF) was measured by Western blotting and an accumulation of γH2AX foci 6 hours after radiotherapy was measured after PP2 treatment. The effect of PP2 on migration, invasion, and vasculogenic mimicry formation (VMF) of U251 cells was evaluated. In an orthotopical brain tumor model with U251 cells, PP2 was injected intraperitoneally with or without oral TMZ before, during and after whole brain radiotherapy. Bioluminescence images were taken to visualize in vivo tumors and immunohistochemical staining of VEGF, CD31, EphA2, and hypoxia-inducible factor 1a was performed. RESULTS: PP2 increased radiosensitivity of U251 and T98G cells without decreasing survival of normal human astrocytes. Chemoradiotherapy with PP2 and TMZ resulted in increased accumulation of γH2AX foci. PP2 induced overexpression of E-cadherin and suppression of MMP2, VEGF, and EphA2. PP2 also compromised invasion, migration, and VMF of U251 cells. In brain tumors, chemoradiotherapy with PP2 and TMZ decreased tumor volume best, but not statistically significantly compared with chemoradiotherapy with TMZ. The expression of VEGF and CD31 was suppressed in PP2-treated tumors. CONCLUSION: PP2 enhances radiosensitivity of malignant glioma cells and suppresses invasion and migration of U251 cells. Chemoradiotherapy with PP2 and TMZ resulted in non-significant tumor volume decrease.
