PURPOSE: The platelet synthesis is extremely variable after intravenous immunoglogulin injection (IVIG) in acute idiopathic thrombocytopenic purpura (ITP). To investigate the size variation of platelet according to the time sequence of ITP, the relationship between platelet number and mean platelet volume (MPV) was analyzed. METHODS: Twenty acute ITP patients who showed abrupt increase of platelets within 48 hours after IVIG were selected. We checked the platelet number and MPV, thereafter analyzed the relationship. RESULTS: At the early phase of ITP before IVIG, MPV was normal or slightly decreased. However, as the number of platelet increased after IVIG, MPV increased together until platelet count reached 100, 000/mm3. The MPV decreased afterward, therefore the platelet mass was preserved. CONCLUSION: At the early phase of ITP before the increase of platelet, MPV decreased in spite of low number of platelet. After IVIG, there was an abrupt increase of MPV with platelet number. There might be some contributing factors for these, particularly IL-6, IL-11 and thrombopoietin. Now, we need more experimental data to explain these findings.

BACKGROUND: There are only a few studies regarding the causes of treatment failure for tuberculosis. Therefore, this study aimed to determine the causes of intractable tuberculosis. METHODS: M.tuberculosis, differentiated MOTT (Tycobacterium Other Than Tuberculosis) were isolated, and the RFLP (Restriction fragments length polymorphisms) pattern was analyzed from 204 patients with pulmonary tuberculosis and 53 suffering from neck tuberculosis. The IL-1β, IL-12, *1 IFNγ and *2 TNFαblood levels were measured. All patients were regularly followed for 18 months after treatment. RESULTS: There was no correlation between the RFLP patterns of M.tuberculosis treatment failure. From the 204 cases, 31.9% were intractable. The characteristics of patients with intractable tuberculosis were old age, being male and recurrent cases. The causes of treatment failure were identified as follows ; a decrease in the IL-12(59.4%) concentration, drug resistant strain(54.7%), irregular medication(15.4%), MOTT(6.2%) and a heavy infection(4.6%). The causes of all cases of intractable tuberculosis could be investigated. The IL-12 concentration in the blood was significantly lower in the intractable cases, where it disclosed a maximum sensitivity(64.7%) and specificity(75.4%) at 165.0 pg/ml. Most of the 53 cases on neck node tuberculosis were treated successfully. Therefore, we were unable to analyze the cause of treatment failure. CONCLUSION: A decrease in the blood IL-12 concentration and drug resistant strains were identified as the most significant causes of treatment failure for tuberculosis. In Korea, infection by clusters were prevalent, but no difference in the clinical course between clusters and non-clusters could be found.

Recently, the efficacy of immuno-oncologic agents for advanced hepatocellular carcinoma (HCC) has been proven in several trials. In particular, atezolizumab with bevacizumab (AteBeva), as a first-line therapy for advanced HCC, has shown tremendous advances in the IMBrave150 study. However, second or third-line therapy after treatment failure with AteBeva has not been firmly established. Moreover, clinicians have continued their attempts at multidisciplinary treatment that includes other systemic therapy and radiotherapy (RT). Here, we report a case that showed a near complete response (CR) of lung metastasis to nivolumab with ipilimumab therapy after achieving a near CR of intrahepatic tumor using sorafenib and RT in a patient with advanced HCC who had experienced treatment failure of AteBeva.

BACKGROUND: Intravenous anesthetics may modify airway responsiveness. The author investigated the relaxant effect of thiopental, ketamine, and propofol on isolated rat tracheal smooth muscles. METHODS: The trachea of the rat was dissected and cut into 3-mm rings. The rings were mounted in a water-jacked organ bath filled with Krebs solution aerated with 95% O2 and 5% CO2 at 37degreesC. Thiopental, ketamine, and propofol were given randomly to each ring preconstricted with EC50 of acetylcholine from 10(-6) to 10(-3) M. The relaxation response was the tension during anesthetic equilibration, expressed as a percentage of the tension from EC50 of acetylcholine. RESULTS: Thiopental and propofol (10(-5) to 10(-3) M) relaxed acetylcholine-induced contractions in a dose dependent manner (P < 0.05). Ketamine in doses of 10(-5) and 10(-4) M constricted acetylcholine-induced contractions by 3.2% and 16.5% respectively (P < 0.05). But ketamine in a dose of 10(-3) relaxed acetylcholine-induced contractions by 76.4% (P < 0.05). The relaxation of tracheal smooth muscles was greatest in thiopental, and was least in ketamine (P < 0.05). CONCLUSIONS: All three intravenous anesthetics have an excellent relaxation of tracheal smooth muscles in rats, except in doses of 10(-5) and 10(-4) M of ketamine.

The advance of the immunobiology clarifies the nature of non-Hodgkin's lymphoma(NHL). In addition the proceed in the immunophenotyping renders the classification of NHL. According to the Revised European American Lymphoma(REAL) classification, classified by the etiologic factors, molecular biological characteristics, immunophenotype, cytogenetics and histologic feature, nasal T/NK-cell lymphoma(=angiocentric lymphoma) belongs to the category of peripheral T-cell and natural killer cell lymphoma. Nasal T/NK-cell lymphoma is a distinct clinicopathologic entity characterized by progressive necrotic lesions in the nasal cavity, nasopharynx, and palate. The cellular origin of this tumor has been controversial. Although most nasal T/NK-cell lymphomas are of NK-cell lineage, being CD56+, negative for surface CD3(Leu4), and unassociated with rearrangements of the T-cell receptor genes, other minor variants have been reported. This lymphoma is a rare disease and usually experienced in adult. Recently, we experienced a rare type lymphoma, nasal T/NK-cell lymphoma, in 14 years old boy. His soft mass occupied the right nasal cavity including the nasal septum and turbinate. Pathologically this nasal mass showed the infiltration into the vascular wall, illustrating angiodestructive lesion. The cellular origin was NK-cell lineage, being CD56+ and negative to CD3. Now, we report the case with a brief review of related literatures.

PURPOSE: Although the incidence of microsatellite instability (MSI) accounts for 10-15% of cases of colorectal cancer, its clinical application for all colorectal cancers has widened. We attempted to identify clinical and pathological parameters that may be helpful in selection of patients with MSI-high (MSI-H). MATERIALS AND METHODS: A total of 120 resected colorectal cancers were enrolled retrospectively for this MSI study. Polymerase chain reaction (PCR) and denaturing high performance liquid chromatography and/or real time PCR methods with five markers and immunohistochemistry (IHC) for MLH1 and MSH2 were performed for analysis of cancer and blood specimens. Clinico-pathologic parameters, including IHC, were investigated in order to determine their usefulness as predictive factors of MSI. RESULTS: Among 120 cases of colorectal cancer, MSI was observed in 15 cases (12.5%), including 11 cases of MSI-H and four cases of MSI-low. Patients with MSI were younger, less than 50 years old, had a family history of cancer, Rt. sided colon cancer and/or synchronous multiple colorectal cancer, mucinous histologic type, and serum carcinoembryonic antigen group in the normal range. Results of multivariate analysis showed Bethesda guidelines, Rt. sided and/or synchronous multiple colorectal cancer, and negative expression of IHC for MLH1, which was consistently associated with MSI-H. MSI-H colorectal tumors have met at least one of these three parameters and their sensitivity and specificity were 100% and 72.5%, respectively. CONCLUSION: Bethesda guidelines, tumor location, and negative expression of MLH1 protein are important parameters for selection of patients with colorectal cancers for MSI testing. MSI testing is recommended for patients showing any of these three parameters.

PURPOSE: To report the relationship between voiding dysfunction and reflux, renal scars and the common findings related to voiding dysfunction in patients with vesico-ureteral reflux (VUR). MATERIALS AND METHODS: Between March 2002 and February 2004, 56 children underwent a video-urodynamic study (video-UDS) for evaluation of VUR. The grade of VUR, various findings of voiding dysfunction and the maximal intravesical pressure (maxPves) were assessed during voiding, and severity of renal scars were assessed via video-UDS and DMSA scans, respectively. RESULTS: Voiding dysfunction was diagnosed in 30 patients (53.6%). The findings of voiding dysfunction were uninhibited contraction (14 patients), detrusor sphincter dyssynergia (15 patients) and bladder neck opening during the filling phase (17 patients). Urethrovaginal reflux and after contraction were noted in 6 and 8 patients, respectively. In the voiding dysfunction group, the mean VUR grade was 3.4, while this was 2.6 in 42 renal units of the normal voiding group (p=0.023). The mean maxPves values during voiding in the voiding dysfunction and normal voiding groups were 107.7 and 77cmH2O, respectively (p=0.002). On evaluation of the relationship between voiding dysfunction and the extent of renal scarring [no scar, single scar, multiple scars, reduced size], the existence of voiding dysfunction resulted in more severe forms of renal scarring (p=0.034). CONCLUSIONS: Voiding dysfunction can cause or aggravate VUR or urinary tract infection due to an increased intravesical pressure during voiding, which can ultimately cause permanent renal damage. Therefore, treatments, such as anticholinergic drugs or biofeedback, must be performed in patients with combined VUR and voiding dysfunction for a better treatment outcome.

Maple syrup urine disease(MSUD) is an autosomal recessive disorder involving the metabolism of the branched-chain amino acids(BCAA) such as leucine, isoleucine and valine. The disorder is due to a defect in branched-chain alpha-ketoacid dehydrogenase(BCKAD) and the classic form causes rapid progressive and overwhelming illness beginning in the first weeks of life, present with poor feeding, lethargy, change in muscle tone, acidosis, seizures and coma. The goal of therapy in acutely ill patients with MSUD is an immediate reduction in the plasma levels of the BCAAs and branched-chain ketoacids. In this report, we describe an infant with MSUD who was treated by dietary therapy alone. During the therapy, acrodermatitis enteropathica-like syndrome developed with low plasma isoleucine concentration while she was receiving a formula deficient in BCAAs.
