Compliance of epileptic patients is one of the most important factors for adequate therapy. Recently, it had been shown that the variability of three serial measurement of the serum levels of antiepileptic drug(AED) may be used as an indication of the degree of compliance. Coefficient variation(CV) of serum drug levels calculated by only one AED had been used to determine the compliance in epileptic patients who took multiple AEDs. We attempted to evaluate the CV of AEDs and then find the objective clue of compliance and the compatible therapeutic planing according to CV. Ninety seven epileptic patients of outpatients department of the Gyengsang National University Hospital were entered to this study. All patients were taking medication at least for 6 months without any changes of drug regimen. Patient's information was acquired by reviewing the chart and interview with questionnaire. With these informations, we determined the compliance of the patients. Antiepileptic serum levels were measured three times at intervals of at least two to four weeks apart, and their CV was calculated. We compared the CV between the compliant and non-compliant group in each AED(phenytoin, carbamazepine , valproic acid) and three drugs in the compliant group. The mean CVs of phenytoin, carbamazepine and valproic acid in the compliant group were 18.3+/-13.0, 15.2+/-10.2 and 23.8+/-8.9, respectively(mean+/-SD). The mean of CV in the compliant and the non-compliant group were 17.9+/-10.9 and 38.8+/-27.2, respectively. The CVs of the compliant group were significantly lower than those of the non-compliant group(p<0.05). However, CVs had no significant difference between three antiepileptic drugs. This study showed that CVs of AEDs were not different between each AEDs, even though they possess different pharmacokinetic properties. Therefore, the CV of one AED can be used in determining the compliance of the epileptics who are taking multiple AEDs.

PURPOSE: The mechanisms, which alter urinary bladder muscle function during infectious cystitis, are poorly understood. The objective of this study was to identify potential resident targets for endotoxin lipopolysaccharide(LPS) within normal bladder smooth muscle and test the hypothesis that LPS induces an inflammatory response within the bladder muscle and that this is associated with a decrease in muscle contractility. MATERIALS AND METHODS: Male rats were studied 24 hours after a single bolus i.p. injection of LPS(15mg/kg). Whole-mount preparations of the bladder muscle were immunohistochemically stained for neutrophils(myeloperoxidase), macrophages(ED2), activated leukocytes(LFA-1) and mast cells(FITC-Avidin). Contractile activity was assessed from muscle strips of the bladder in response to bethanechol(0.3-300microM). Voiding frequency and urine volume for 24 hours were measured using metabolic cage. Cystometry was performed to measure the intravesical bladder pressure. RESULTS: Using the resident macrophage marker ED2, dense network of macrophages were observed within the bladder muscle of control and LPS treated rats. Few neutrophils(myeloperoxidase-positive cells, 2.3 +/- 0.38 cells, x200) were detected in whole-mounts of bladder muscle of control rats, while LPS pretreatment resulted in a significant increase in the number of neutrophils which demonstrate inflammatory response(10.8 +/- 1.70 cells, x200, p<0.001). LFA-1 immunohistochemistry demonstrated an increased presence of LFA-1 positive cells in bladder muscle of LPS treated rats, which had a morphology similar to both neutrophils and resident macrophages. The expression of LFA-1 is known as a marker of cells that are in an activated state. LPS pretreatment resulted in a significant reduction in bladder muscle contractions in response to bethanechol(i.e. control = 0.049 +/- 0.010 vs. LPS= 0.029 +/- 0.003 gr/mm2/sec, 100microM, p<0.05). Voiding frequency of LPS treated rats was significantly increased compared to that of control rats. In LPS treated rats, voiding phase representing bladder contractility in cystometry was observed. CONCLUSIONS: These data demonstrate that a single intraperitoneal injection of LPS initiates an inflammatory response within the bladder muscle that is associated with a decrease in the functional activity of the bladder. We hypothesize that secretions from the resident macrophages and extravasated leukocytes within the muscle cause the observed suppression in bladder muscle activity in vitro.

Central diabetes insipidus (CDI) is a clinical syndrome that result from a failure of the neurohypophyseal axis to produce or release a sufficient quantity of arginine vasopressin (AVP) to permit normal function of the urinary concentrating mechanism. Polyuria and polydipsia are the symptoms associated with CDI. The most common cause of CDI is idiopathic variety and head trauma, neurohypophyseal surgery, primary or metastatic brain tumors acount for most of the remaining cases. CDI in Langerhans cell histiocytosis (LCH) is thought to be to infiltration of the hypothalamus-neurohypophyseal system. We report a patient with CDI and LCH underwent water depriviation test, MR imaging of the pituitary-hypothalamic region, and VATS associated open lung biopsy.

Etretinate(Ro 10-9359), an aromatic analogue of vitamin A acid, has been known to be effective in the treatment of psoriasis, Darier's disease, pityriasis rubra pilaris, ichthyosis, and palmoplantar keratoderma when administered orally. In this experiment, we compared the therapeutic and side effects between a group with high dose therapy(initially 75mg of etretinate a day) and an another group with low dose therapy(initially 40mg of etretinate a day). We also observed whether the pretreatment followed by combined treatment with vitamin E could potentiate the therapeutic effect as well as reduce the side effects of oral etretinate. This experiment comprised 102 moderate to severe psoriatic patients. The following results were obtained from this experiment. 1. Fifty-six among 92 patients(61%) who were treated with etretinate for more than 4 weeks showed good to excellent therapeutic effect. 2 The high dose therapy was more effective, but showed more side effects than low dose therapy. 3 Vitamin E did not potentiate the effect of etretinate. In low dose therapy, the pretreatment followed by combined treatment with vitamin E showed a tendency to reduce the side effects of etretinate.

The purpose of this study was to evaluate the sequential signal intensity changes in post-traumatic vertebral compression fractures of varying ages. Sixty-six patients with 115 post-traumatic vertebral compression fractures underwent MR imaging. The ages of fractures at the time of MR images ranged from 1 day to 6 years. Sequential follow-up MR imagings were obtained in 4 patients for 2 years after initial MR examination. The fracture sites in all 52 fractures with traumatic events less than 3 months prior were hypointense on T1-weighted images and hyperintense on T2-weighted images (type I). A type I fracture could be subdivided into 3 patterns depending on its morphologic appearance: diffuse (type Ia); patchy (type Ib); and bandlike (type Ic). In 12 fractures of 3 to 5 months after trauma, six showed focal hypointensity (type II) in all pulse sequences, and six showed isointensity (type IV). Four of 51 fractures with trauma over 5 months showed focal hyperintensity on T1-weighted images and isointensity on T2-weighted images (type III); and the remaining 47 fractures showed isointensity on all sequences (type IV). In conclusion, MR imaging is useful in predicting the age of known traumatic compression fractures, so familiarity with these sequential MR findings would be helpful in distinguishing benign from malignant fractures.

BACKGROUND/AIMS: Helicobacter pylori infection is linked to the development of gastric cancer. H. pylori-associated gastric inflammation is considered to be the first important step in the histogenesis of such neoplasia. However, studies that compare proteome of gastric mucosa infected with or without H. pylori are lacking. METHODS: We employed proteomics analysis on the endoscopic biopsy specimens of gastric mucosa obtained from two groups (30 cases): healthy subjects without H. pylori infection (15 cases), and gastritis patients with H. pylori infection (15 cases). The pooled proteins obtained from gastric mucosa infected with or without H. pylori were separated by two-dimensional gel electrophoresis and analyzed by a computer-aided program. The altered protein expressions were then identified by mass spectrometry and validated by Western blotting and immunohistochemistry. RESULTS: On mass spectrometry using MALDI TOF(TM) Analyzer, the up-regulation of Keratin 1, ezrin, adenosine triphosphate (ATP) synthase subunit alpha mitochondrial isoform c, Keratin type I cytoskeletal 19, and Keratin type I cytoskeletal 9 were identified; in contrast, 71 kd heat shock cognate protein, ATP synthase subunit alpha mitochondrial precursor, and annexin IV were down-regulated. Among them, membrane cytoskeleton linker ezrin was validated using Western blot and immunohistochemistry. CONCLUSIONS: Expression of ezrin was significantly different between the gastric mucosa with and without H. pylori infection. Therefore, ezrin could be considered a promising potential molecular marker for detecting H. pylori infection in gastric mucosa.

OBJECTIVE: Tremor, either essential tremor or Parkinsonian tremor, has been effectively and safely treated by lesioning the ventral intermediate(Vim) nucleus of the thalamus with or without mircroelectrode recording. The authors evaluate the treatment outcome of sixteen tremor patients who had been treated with thalamotomy without microelectrode. METHODS: Between September, 2001, and December, 2003, sixteen tremor patients were treated with thalamotomy without microelectrode recording. Twelve patients suffered from Parkinsonian tremor and four patients were essential tremor patients. The male to female ratio was 1.6 to 1 with median age of 59.6 years (range; 39-74 years). Under local anesthesia, a 3mm hole was made using a hand-held twist drill, and the dura mater was penetrated with a 1.2mm sharp drill beat. Radiofrequency(RF) electrode was placed in the Vim nucleus of thalamus. With intraoperative macrostimulation, RF lesion was made. Postoperative CT scan and/or MR imaging was performed to confirm the localization of the target lesioned. Preoperative and postoperative tremor was evaluated with simple tremor severity scale and the development of complications related with the procedure was closely reviewed at the immediate postoperative period and the last follow-up. RESULTS: It produces immediate relief in up to 98.4% of the patients. There were no development of complications related with procedure, all patients discharged one or two days after surgery. CONCLUSION: Vim thalamotomy without microelectrode recording is a safe and effective procedure to control the tremor with minimal morbidity. Intraoperative macroelectrode stimulation safely localizes the Vim nucleus target of the thalamus for the treatment of patients with tremor.

Pulmonary edema is a major cause of mortality due to acute lung injury (ALI). The involvement of protein kinase C-delta (PKC-delta) in ALI has been a controversial topic. Here we investigated PKC-delta function in ALI using PKC-delta knockout (KO) mice and PKC inhibitors. Our results indicated that although the ability to produce proinflammatory mediators in response to LPS injury in PKC-delta KO mice was similar to that of control mice, they showed enhanced recruitment of neutrophils to the lung and more severe pulmonary edema. PKC-delta inhibition promoted barrier dysfunction in an endothelial cell layer in vitro, and administration of a PKC-delta-specific inhibitor significantly increased steady state vascular permeability. A neutrophil transmigration assay indicated that the PKC-delta inhibition increased neutrophil transmigration through an endothelial monolayer. This suggests that PKC-delta inhibition induces structural changes in endothelial cells, allowing extravasation of proteins and neutrophils.

Neuroendocrine carcinoma of the colon is a very rare entity. However, this type of tumor is known to have aggressive progression and poor prognosis. A case of a 72-year-old male is presented in this report. A 3 cm sized tumor was found on the rectum with multiple liver metastases. The pathological findings including a positive immunohistochemical staining for synaptophysin and cytokeratin done with colonoscopic biopsy and liver biopsy confirmed the tumor as a neuroendocrine carcinoma. The nomenclature and definition of this disease still remains somewhat unclear, and not a small population of this disease may thus have been misdiagnosed and treated as other less aggressive entities, such as carcinoid tumor. The necessity to make an accurate differential diagnosis in such cases is thus emphasized because of different treatments and clinical courses. For its rarity and clinical significance, we report this case with a review of the literatures.
