BACKGROUND: Intermediate myasthenia syndrome(IMS) is thought to have clinical importance because it may cause sudden respiratory failure during the recovery phase of a cholinergic crisis of organophosphate poisoning. We designed this study to identify the prevalence, the inducing agent, clinical predictor, and the proposed treatment of IMS. METHODS: Patients who had admitted with the diagnosis of acute organophosphate poisoning from 1992 to 1998 at two teaching hospitals were enrolled in this study. We selected the cases of IMS based on a review of medical records using modified He's criteria. RESULTS: Twelve(12) out of 110 patients with acute organophosphate poisoning were diagnosed for a prevalence at 10.9%. The drug inducing IMS were identified as dichlorvos, fenthion, EPN, methidathion, and phosphamidon. The occurrence of IMS was not related to either the initial treatment with atropine and pralidoxime, or the level of serum cholinesterase. Complications were pneumonia, sepsis, pancreatitis, and pseudomembranous colitis, etc. Eleven(11) patients were discharged without sequelae, and one patient was discharged as a hopeless care. CONCLUSION: This study suggests that IMS is not rare, so close observation is required to detect IMS in organophosphate-poisoning patients. Also, more studies are required to find predictors and treatments.

PURPOSE: Neuroinflammation is mediated by activation of microglia implicated in the pathogenesis of neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease. Inhibition of neuroinflammation may be an effective solution to treat these brain disorders. Petalonia binghamiae is known as a traditional food, based on multiple biological activities such as anti-oxidant and anti-obesity. In present study, the anti-neuroinflammatory potential of Petalonia binghamiae was investigated in LPS-stimulated BV2 microglial cells. METHODS: Cell viability was measured by MTT assay. Production of nitric oxide (NO) was examined using Griess reagent. Expression of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) was detected by Western blot analysis. Activation of nuclear factor κB (NF-κB) signaling was examined by nuclear translocation of NF-κB p65 subunit and phosphorylation of IκB. RESULTS: Extract of Petalonia binghamiae significantly inhibited LPS-stimulated NO production and iNOS/COX-2 protein expression in a dose-dependent manner without cytotoxicity. Pretreatment with Petalonia binghamiae suppressed LPS-induced NF-κB p65 nuclear translocation and phosphorylation of IκB. Co-treatment with Petalonia binghamiae and pyrrolidine duthiocarbamate (PDTC), an NF-κB inhibitor, reduced LPS-stimulated NO release compared to that in PB-treated or PDTC-treated cells. CONCLUSION: The present results indicate that extract of Petalonia binghamiae exerts anti-neuroinflammation activities, partly through inhibition of NF-κB signaling. These findings suggest that Petalonia binghamiae might have therapeutic potential in relation to neuroinflammation and neurodegenerative diseases.

The diffuse large B-cell lymphoma category of the Revised European American Classification of Lymphoid Neoplasms (REAL) encompasses different morphologic lymphoma subtypes in a single entity, especially the diffuse large cell (DLC) and the immunoblastic (IBL) subtypes by Working Formulation (WF). The aim of this study is to determine the influence of the morphologic subdivision within this category with respect to clinical outcome and proliferative index using Ki-67 immunostainig combined with image analysis. We retrospectively reviewed 74 patients from 1990 to 1996, who were diagnosed with diffuse large B-cell lymphoma. All cases were reclassified according to REAL and Working Formulation (WF), and Ki-67 immunostaining was performed in all the cases. Fifty-eight cases (78.4%) were classified as DLC and 16 cases (21.6%) as IBL, according to WF. Twenty one cases (28.4%) showed nodal involvement and 53 cases (71.6%), extranodal involvement. All cases were found to display a variable degree of nuclear Ki-67 staining. A proliferative index of 50% or higher identified a group of patients (77%) who had poor clinical results. Overall survival was significantly reduced in these patients displaying high Ki-67 associated proliferative index compared to those with a low proliferative index (p=0.007). 5-year survival estimates were 93% in the low proliferative index group and 55% in the high proliferative index group. A multivariate regression analysis incorporating commonly used clinical prognostic factors confirmed the independent effect of proliferation index on survival. Moreover, all of the 16 IBL cases showed Ki-67 positivity of 50% or higher, which correlates with the poor clinical outcome compared to 70.7% of DLC (p=0.014). We conclude that subdivision of the diffuse large B-cell lymphoma category of the REAL classification is necessary in terms of prognostic significance in correlation with Ki-67 proliferative index.

Desmoid tumor is rare neoplasm originated from fibrous sheath or musculoaponeurotic structure. It is classified as benign tumor histologically, but clinically, it has malignant characteristics due to its infiltrative growth to adjacent organ and frequent local recurrence. Especially, mesenteric desmoid tumor shows poor prognosis because of its symptoms of pain, intestinal obstruction, ureter obstruction and fistula formation and high frequency of recurrence. We experienced a case of mesenteric desmoid tumor in a 64-year-old woman with a painless abdominal mass. Laparoscopic exploration was performed and 10 cm sized mesenteric mass was identified, which resected widely and the diagnosis was confirmed with desmoid tumor by pathologic report. We reviewed the feature of the mesenteric desmoid tumor, that is, pathophysiology, clinical presentations, diagnosis, treatment and prognosis.

PURPOSE: This study is to introduce our preliminary experience of the Doppler-guided hemorrhoidal artery ligation and Rectoanal repair (DG-HAL & RAR) as a new treatment for symptomatic or prolapsed hemorrhoids. METHODS: A Doppler probe incorporated proctoscope was inserted under the lithotomy position and the location of the hemorrhoidal artery was identified. The identified artery was ligated as a 'figure of eight' method with an absorbable suture into the submucosa. Then the prolapsed hemorrhoidal pile was lifted at the rectal mucosa by continuous suture to 5 mm above the dentate line and tied. The procedure was repeated at the 1, 3, 5, 7, 9, and 11 o'clock positions. We evaluated post-operative hospital stay, degree of pain, time to return to work, and recurrence. RESULTS: The patient's mean age was 50.2+/-15 years old and the mean follow-up time was 415+/-75 days. The constitution of the type of internal hemorrhoids was as follows: Grade II: 13, Grade III: 16, and Grade IV: 5. The mean operation time was 35 minutes and post-operative hospital stay was 1.4 days. The mean time it took to return to work was 1.8 days. There were no severe pains requiring injection of analgesics or other severe complications. So far, 2 patients have had recurrence of symptoms. CONCLUSION: The DG-HAL & RAR is a safe and less painful procedure. The DG-HAL & RAR is an effective alternative for the treatment of symptomatic or prolapsed hemorrhoids.

A 63-year-old woman was referred to a breast surgeon with a breast mass discovered incidentally during follow-up study after colon cancer surgery. Invasive adenocarcinoma was revealed on core needle biopsy. Wide excision of the breast including the tumor was performed. On standard histological examination the tumor showed features of moderately differentiated adenocarcinoma. The immunohistochemistry study revealed positive results for cytokeratin (CK)20 and CDX2, but negative for CK7. These are typical characteristics for colon cancer. Considering her history of subtotal colectomy for sigmoid colon cancer, it is presumable that the mass in the breast was of colonic origin, and it was an extremely rare case of metastasis to the breast from primary colorectal neoplasm. Although the instance is rare, clinicians should keep the possibility of breast metastasis from colorectal cancer in mind for early and correct diagnosis.

PURPOSE: Granulomatous mastitis (GM), reported for the first time by Kessler and Wolloch in 1972, is a rare and benign inflammatory lesion of the breast. The etiology of GM is currently unknown, but some reports have suggested autoimmunity. The aim of this study was to evaluate the clinical characteristic, clinical presentations and radiological features of GM. METHODS: A chart review was performed for 23 patients, with GM confirmed by a pathological examination, between July 1999 and December 2005. A retrospective review of the clinical and radiological finding, as well as the cytological results of the patients was undertaken. RESULTS: The ages of these patients ranged between 29 and 74 years, with a mean of 39.7 years. The median follow-up was 8 months. Twenty patients (87%) presented with a mass as the chief complaint, with a median size of 2.56 cm (range 0.78~6.5 cm). Eight patients (34.8%) had radiological findings suspicious of malignancy. Tuberculosis was diagnosed using Tb-PCR in 1 patient. Twenty-two of the 23 patients underwent a wide excision, and the one remaining patient underwent incision and drainage. One of 23 patients had a recurrent disease. CONCLUSION: GM is a rare breast disease, which clinically mimics cancer. As radiological imaging, such as mammography or ultrasonography, are unreliable in distinguishing GM from breast cancer, further special examinations, for example FNAB and gun biopsy, are necessary. The single most important differential diagnosis of GM is tuberculosis, especially in developing countries. We suggest that the evaluation for tuberculosis is essential for the differential diagnosis of GM using clinical and pathological methods.
