A 25 year old patient who had low back pain and sciatica was diagnosed as having a lumbar intraspinal extradural synovial cyst adjacent to a facet joint between the third and fourth lumbar vertebrae. The extradural defects defined with positive contrast myelography and postmyelographic computed tomographic scanning were posterolateral to the dural sac. Biopsy revealed the findings compatible with synovial cyst. Treatment consisted of laminectomy and surgical excision of the cyst.

Recent investigations have revealed that autocrine growth factors and their receptors are closely related and play an important role in controlling cancer cell growth. We performed an immunohistochemical study on the expression of epidermal growth factor (EGF), transforming growth factor-alpha (TGF-alpha), epidermal growth factor receptor (EGF-R), c-erbB-2, and PCNA labelling index in 60 cases of human gastric carcinomas. TGF-alpha was detected in 38 cases (63.3%), EGF in 26 cases (43.3%), EGF-R in 44 cases (73.3%), and c-erbB-2 in 18 cases (30%). These growth factors, EGF-R and c-erbB-2, were found more often in advanced gastric cancers. The PCNA labeling index was significantly higher in tumors with the expression of EGF-R or c-erbB-2. Tumors with simultaneous expression of EGF, TGF-alpha, EGF-R and c-erbB-2 was associated with a high PCNA labeling index. A correlation was observed between the synchronous expression of growth factors and its receptors and histological differentiation. The results suggest that the expression of EGF, TGF-alpha, EGF-R and c-erbB-2 are closely related and plays an important role in the growth and progression of human gastric carcinoma.

We report two cases of hyalinizing trabecular carcinoma (HTC) of the thyroid gland. These two patients were euthyroid women aged 36 and 65 years of age. The tumors were encapsulated and measured 0.8 and 4.0 cm in diameter, respectively. Histologically, the tumors were composed of a compact proliferation of cells in a lobular and trabecular pattern with an intervening hyalinized, fibrotic vascular stroma. Occasionally the cells were arrayed in microfollicles. Multiple and serial sections showed cords of tumor cells invading into the capsule in both cases and vascular invasion in one case. These findings suggested that HTCs are a malignant counterpart of hyalinizing trabecular adenoma, similar to conventional follicular tumor. Positive immunostaining of tumor cells for thyroglobulin and negative staining for high molecular weight cytokeratin, cytokeratin 19, neuron specific enolase, chromogranin, and synaptophysin allowed distinction from medullary carcinoma. Even though HTCs are an heterogeneous group of tumors, the present two cases are probably variants of follicular carcinoma rather than papillary carcinoma.

Adenoid basal cell tumor of the prostate is a rare tumorous lesion that can be misdiagnosed as adenocarcinoma of the prostate. The malignant potential of adenoid basal cell tumor remains uncertain due to small number of reported cases. This 66-year-old man presented with symptoms of urinary tract obstruction. Under the impression of benign prostatic hyperplasia, a transurethral resection of the prostate (TURP) was performed. The patient was alive with no evidence of recurrence or metastasis 15 months after TURP. Microscopically, most of the lesions were composed of nodular collections of small nests of basaloid cells with peripheral palisading, and clusters of tumor cells forming cribriform pattern. Multiple areas of basal cell hyperplasia and atypical basal cell hyperpalsia were also observed. The coexistence of basal cell hyperplasia, atypical basal cell hyperpalsia, and adenoid basal cell tumor with cribriform pattern in this case supports a morphologic continuum from the benign hyperplastic lesion to malignant neoplasia.

PURPOSE: The Aim of this study was to find the value of intravesical permeability of potassium as a diagnostic measure of the interstitial cystitis and to find importance of intravesical mucosal layer by intravesical instillation of potassium chloride solution. MATERIALS AND METHODS: 20 patients with interstitial cystitis and 20 normal subjects without UTI, frequency and urgency underwent intravesical challenge with 40ml water and 40ml of 400meq/L potassium chloride solution. After 5 minutes, patients were asked about increase or decrease of urgency or suprapubic pain and subjective response of urgency or suprapubic pain were recorded on a scale of 0 to 5. RESULTS: Neither normal subjects nor patients with interstitial cystitis reacted to water administered intravesically. There was marked sensitivity to intravesical potassium in 85% of patients with interstitial cystitis versus 10% of normal controls (p<0.05). CONCLUSIONS: Diffusion of urinary potassium ion into the bladder interstitium may induce sensory symptoms, damage the tissue and be a major toxic factor in the pathogenesis of interstitial cystitis. Intravesical potassium sensitivity can be a reliable method for detecting abnormal epithelial permeability and useful diagnostic test for interstitial cystitis.

BACKGROUND: Epidermal growth factor (EGF) is a 6Kd polypeptide hormone produced by the glands of the gastrointestinal tract, namely the salivary and Brunner's glands. In fetal and neonatal life, EGF appears to play an important role in the developement of the gastrointestinal tract and the liver. METHODS: EGF and EGFR (EGF receptor), which play important roles in the onset of liver regeneration, were investigated with regard to the proteins and mRNA according to the developmental periods of the livers of prenatal rats (24 female Spraque Dawley rats weighting from 200 to 250g) by using immunohistochemical stains, the solution reverse transcription polymerase chain reaction (RT PCR), and in-situ (IS) RT PCR. RESULTS: 1) On the immunohistochemical stains, the immunoreactivities for EGF started to be observed at an early stage of the developing rat liver. As the developmental stage progressed, the reactivites were observed in embryo tissues containing epithelial cells. The strongest reactivity for EGF was found from the 17th to the 19th day after pregnancy and decreased gradually till full term. The reactivities of EGFR were detected earlier than those of EGF. 2) In solution RT PCR studies, EGF and beta-actin (house keeping gene) were detected in all developmental stages, reached a peak level at the 18th day after pregnancy, and decreased gradually till the final developmental stage. The peak level of EGF beta-actin was about 4 times higher than the lowest level. 3) The expressions of EGF in IS RT PCR were detected mainly on hepatocytes rather than Kupffer cells and endothelial cells. CONCLUSIONS: The EGF expression was observed over the entire time of development for experimental rat livers and is related strongly to growth and developing rate of liver.

Nasal osteotomy for aesthetic results is required in patients who have broad nasal bone. Since the procedure is difficult, many operators hesitate the surgery. From January 2007 to July 2009, we performed 77 cases of nasal osteotomy, consisting of paramedian oblique medial osteotomy or median oblique-medial osteotomy and percutaneous lateral osteotomy. Most of the patients had satisfying results, however three patients had asymmetric shape and inappropriate inward movement of nasal bone which required revision with percutaneous lateral osteotomy. Osteotomy procedure varies, depending on surgeon's preference and experience, however, each surgeon should be aware of good and weak points of those procedures and use the most suitable method. In order to achieve maximal satisfying results, preoperative analysis of patients and minimal invasive handling should be done. Based on these efforts, this method could broadly be used in the aesthetic field.
