A 35 year old woman, gravid 5, multiparous, was admitted to our department at 6 weeks and 5 days of gestation after being diagnosed with cervical pregnancy. Before the evacuation, the uterine arteries were embolized using angiographic techniques. As a result, dilatation and curettage were performed with minimal hemorrhage. We report one case of cervical pregnancy managed, successfully with preoperative uterine artery embolization and evacuation.

T cell lymphoblastic lymphoma is characterized by immature lymphoid cells that are indistinguishable from the lymphoblasts and prolymphocytes of acute lymphoblastic leukemia. Several characteristic clinical features of lymphoblastic lymphoma, with include a high male-to-female ratio, a relatively high incidence in older children and young adults, the frequent presence of mediastinal involvement at the time of diagnosis. Also, this disease is rapidly progressive, and early dissemination to the bone marrow, blood, and central nervous system leads to the evolution of a picture resembling a acute lymphoblastic leukemia. We have experienced a rare case of congenital T-cell lymphoblastic lymphoma in which 1/365 year old female newborn had generalized multiple irregular protruding mass on her body. On bone marrow biopsy, CSF analysis, ultrasonogram and whole body MRI studies. We found metastasized tumor mass to, orbit, abdominal cavity, bulva, skin, and lower extremities. Histopathologically, specimen from mass on the right thigh showed diffuse infiltration of poorly differentiated and immature lymphoid cells in the skelectal muscle and subcutaneous soft tissue. By immunophenotyping studies using anti T cell and B cell monoclonal antibody, these cells were reactive with UCHL-1, MB2, but unreactive with MB1, L26. Based on these findings, the lesion was diagnosed as lymphoblastic lymphoma of the T-cell type, which occurred congenitally. Most T cell lymphoblastic lymphoma are noted, but congenital case was not reported. So we report it with a brief review of literature.

Differential diagnosis of cavitary lung lesions is frequently problematic. We studied 35 patients with cavitary lung lesions, consisting of lung cancer (17 patients). Pulmonary tuberculosis(11 patients), and lung abscess (7 patients). We analysed CT scans in terms of irregularities of the cavity wall, maximum wall thickness, the presence of air-fluid level, location of the cavity within the mass, number of cavities within the mass, size of the cavity and the presence of calcification within the mass. Cancer cavity showed irregular inner (100%) and outer margins(100%), and thick wall (mean, 1.94cm), eccentrical location(94%) and multiplicity within a mass(38%). Tuberculous cavity showed smooth inner (56%) and irregular outer margins(75%), thin wall (mean 0.96cm), central location (62%), and multiplicity in one patient (36%). Abscess cavity showed irregular inner (57%) and outer margins(91%), relatively thin wall (mean 1.0cm), central location (57%), and air-fluid level (86%). CT scan could differentiate malignant lesions from benign condition such as tuberculosis and lung abscess by observing characteristics of the cavities.

5.Laboratory Evaluation of Cobas(R) Integra Automated Chemistry Analyzer.

Korean Journal of Clinical Pathology 1997;17(5):735-742
BACKGROUND: The Cobas(R) Integra is a new automated chemistry analyzer with continuous and random-access features for routine chemistries, specific proteins, electrolytes, therapeutic drugs and drugs of abuse. The system maintains 68 test-specific reagent cassettes on board and have test principles of absorbance photometry, immunoturbidometry, fluorescence polarization and ISE measurements. We evaluated the usefulness of Cobas(R) Integra in the aspect of accuracy, precision, linearity, comparison study, test speed and general performance. METHODS: We evaluated the analytical performance of the Cobas(R) Integra for T. bilirubin, CRP, BUN, creatinine, sodium, potassium, chloride, valproic acid, phenytoin and carbamazepine according to NCCLS guidelines (EP5-T2, EP6-P, EP9-T and GP10-T). RESULTS: In accuracy study, error ranges(%) of most test items, except sodium and chloride, were within analytic goals. In within-run and between-run precision study, Coefficient of variation (CV, %) of most items, except sodium, were lower than limits suggested by College of American Pathologists Survey 1991. The linearities were maintained well in the range of medically significant levels and were statistically acceptable (p<0.001). The comparison study for most items, except sodium and chloride, indicated good correlation with Hitachi 747 and TDx FLx(TM) and correlation coefficients (r) were above 0.98. Throughput was about 450 tests/hr. CONCLUSIONS: Cobas(R) Integra showed satisfactory accuracy, precision, linearity, good correlation with other analyzers and high throughput. So, we concluded that Cobas(R) integra is highly suitable for not only routine use but also emergency tests in medium to large-sized hospitals because of its high productivity and reliability.

The Bcl-2 protein has been shown to block apoptosis induced by a variety of stimuli. We have performed the experiments which cell death can be blocked by the bcl-2 proto-oncogene under moderate(50-100mM) or high ethanol treatment(400-600mM). As a result of morphological changes, and MTT assay, cell death was blocked by Bcl-2 under 100mM ethanol. However, the results of DNA fragmentation and RT-PCR(ICE, and CPP32), immunoblotting(CPP32, and PARP) for SK-pcDNA3 cells(vector only) and SK-Bcl-2 cells(stably expressed bcl-2 gene) were showen to be no significant differences between two cell lines. These result suggested that cell death induced by ethanol was not followed by apoptosis mechanism, and was blocked by the bcl-2 proto-oncogene with moderate ethanol.

More than half of patients presenting with hoarseness show benign vocal cord changes. However, in rare cases with benign mucosal lesions, it can be diagnosed as a malignant disease after histopathological examination. A 53-year-old man with a 30-pack-year smoking history was admitted for the evaluation of hoarseness, and using a laryngoscope, an enclosed, sac-like cystic lesion was detected on the midpoint of the right true vocal cord. The cystic lesion was deemed to be an intracordal cyst and treated with laryngeal microsurgery. However, pathological findings showed squamous cell carcinoma of the larynx arising in the intracordal cyst, which is exceptionally rare. Therefore, even if a benign lesion is initially suspected, a biopsy must be performed on a patient with smoking history to confirm the diagnosis. In conclusion, we report a case of squamous cell carcinoma of the larynx arising in the intracordal cyst.
