Littoral cell angioma (LCA) of spleen is an uncommon vascular neoplasm of littoral cell origin. It is well established that LCA may be associated with other malignancy or autoimmune disorders. We describe a 34-year-old woman with viral hepatitis C associated liver cirrhosis who presented with the incidental finding of LCA. She showed ascites, esophageal varix and drowsy mentality. Abdominal computed tomography (CT) showed multiple benign looking nodules in both hepatic lobes, but no abnormality in spleen. Liver transplantation and splenectomy were performed. Microscopic findings revealed narrow anastomosing vascular channels lined with plump cells that exfoliated into the lumen. Immunohistochemically the lining cells were positive for CD31, CD68 and negative for CD34, consistent with LCA. Herein, a second case of an incidentally detected LCA with cirrhosis, viral hepatitis C associated in Korea is reported.

Temporal triangular alopecia is a triangular or oval shaped non-scarring alopecia, occurring on the temporal side of the scalp, which was first reported by Sabourand in 1950. It usually occurs in the childhood. There is no treatment for this disorder except for surgery. In this article, we report a case of focal alopecia which was successfully treated with micropigmentation.

OBJECTIVES: To evaluate retrospectively, the possible difference in diffusion tensor imaging (DTI) metric of fractional anisotropy (FA) between good and poor surgical outcome cochlear implantation (CI) patients using investigator-independent voxel-wise analysis. METHODS: Eighteen patients (11 males, 7 females; mean age, 5.9 years) with profound sensorineural hearing loss underwent DTI scans using a 3.0 Tesla magnetic resonance scanner. Among the 18 patients, 10 patients with categories of auditory performance (CAP) score over 6 were classified into the good outcome group and 8 patients with CAP score below 6 were classified into the poor outcome group. The diffusion tensor scalar measure was calculated from the eigenvalues of the tensor on a voxel-by-voxel basis from each subject and two-sample t-test evaluation between good and poor outcome subjects were performed for each voxel of FA values, across the entire brain, with a voxel-wise intensity threshold of P<0.0005 (uncorrected) and a contiguous cluster size of 64 voxels. Individual values of FA were measured by using the region-of-interest based analysis for correlation analysis with CAP scores, open sentence and open word scores. RESULTS: Two-sample t-test evaluation using SPM voxel-wise analysis found significantly higher FA values at the several brain areas including Broca's area, genu of the corpus callosum, and auditory tract in good outcome subjects compared to poor outcome subjects. Correlation analyses between FA and CAP scores, open sentence and open word scores revealed strong correlations at medial geniculate nucleus, Broca's area, genu of the corpus callosum and auditory tract. CONCLUSION: Investigator-independent voxel-based analysis of DTI image demonstrated that good outcome subjects showed better neural integrity at brain areas associated with language and auditory functions, suggesting that the conservation of microstructural integrity of these brain areas is important. Preoperative functional imaging may be helpful for CI.

Non-Hodgkin's lymphoma (NHL) is a group of neoplasm affecting the lymphoid system. Follicular lymphoma is typically a slow-growing, indolent form of NHL that accounts for 1/3 of all NHL. It is one of the B-cell lymphomas, generally characterized by multiple relapses after responses to a variety of therapies. When lymphoma relapses, it may occur in the same or a different part of the body from where it occurred originally. Recurrence in the primary site is most common but recurrence in other parts is rarely observed. We experienced a rare case of 70-year-old woman who complained of swelling in the left mouth floor and was diagonosed with a recurrent NHL. It recurred in the sublingual gland after a complete remission of the follicular lymphoma.

BACKGROUND: To evaluate the effects of thoracic epidural anesthesia, with or without bilateral vagotomy, epinephrine-induced arrhythmias were studied in 31 rabbits anesthetized with 1 MAC enflurane. METHODS: Logdose protocol was used for the infusion of epinephrine; its arrhythmic dose being defined as the smallest infusion rate produced four or more continuous or intermittent arrhythmias within 15 seconds. RESULTS: The values (geometric mean) of arrhythmic doses and the plasma concentration of epinephrine during arrhythmia were as follows: 10.21 g.kg 1.min 1 and 83.16 ng/ml in epidural control group; 118.90 g.kg 1.min 1 and 677.76 ng/ml in epidural lidocaine group (p<0.05); 6.34 g.kg-1.min 1 and 96.42 ng/ml in intravenous lidocaine group; 8.65 g.kg 1.min-1 and 44.64 ng/ml in vagotomized-epidural control group; and 12.03 g.kg 1.min 1 and 95.35 ng/ml in vagotomized- epidural lidocaine group. CONCLUSIONS: The data suggest that thoracic epidural anesthesia raises the threshold for enflurane- epinephrine arrhythmias in rabbits and that this effect is eliminated by bilateral vagotomy.

Accidental hanging in infancy and early childhood is not common and the autopsy findings have not been well-known. We experienced five cases of accidental hanging in children in a variety of situations. All cases were concluded as accidental hanging after a comprehensive examination based on the death scene investigation, autopsy findings, and investigation of their background and past history. Two cases happened at slides in a playground and in a kindergarten, the other cases related with by various kinds of cords in their house. As it is not always possible to predict every dangerous circumstance, these cases will be helpful to prevent the cases of accidental hanging.

BACKGROUND: Chemokines and their receptors are important players in tumorigenesis by facilitating tumor proliferation and metastasis. Little is known about the possible function of chemokine receptors in relation to the development and progression of malignant cutaneous tumors. OBJECTIVE: The aim of this study was to determine the chemokine receptor CCR3 expression pattern and the protein expression level in selected malignant cutaneous tumors. METHODS: Four types of cell lines (G361, A431, SK-MEL-2, SK-MEL-24) were analyzed, using Western blotting, for the expression of CCR3 protein. Immunohistochemical staining for CCR3 was done on 36 skin cancer tissue samples that included 16 squamous cell carcinomas (SCCs), 16 basal cell carcinomas (BCCs), 16 malignant melanomas (MMs) and 6 normal tissue samples. RESULTS: Western blot analysis showed that CCR3 protein was more expressed in the MM cell lines (G361, SK-MEL-2,SK-MEL-24) than that in the SCC cell line (A431), and the immunohistochemical analysis showed that CCR3 protein was overexpressed in MM and SCC, it was mildly expressed in BCC and it was hardly expressed in normal tissue. CONCLUSION: This study demonstrated via immunochemistry that CCR3 was more expressed in MM, followed by SCC and BCC. The existence of CCR3 protein may enhance the tumorigenic potential of malignant cutaneous tumors.

A clinical study was performed of the respiratory care of 1309 critically ill patients who had been admitted to respiratory intensive care units (RICU) in 1986 and 1987. 1) The number of patients who needed respiratory care was 691 and the mortality in RICU was 1.45% (10 case) in 1986, and 618 and 2.59% (16 cases) in 1987, respectively. 2) The average duration of ventilatory support was 2.1 days in 1986, and 1.9 days in 1987. The patients of thoracic surgery needed respiratory support for 2.6 days in 1986, and 2.3 days in 1987. 3) The mortalities according to department were:1.42% (6 of 424 cases) in thoracic surgery, 1.89% (2 of 107 cases) in general surgery, 20% (1 of 5 cases) in pediatry surgery, and 7.14% (1 of 14 cases) in gynecology in 1986. In 1987, 2.56% (8 of 312 cases) in thoracic surgery, 4.0% (6 of 150 cases) in neurosurgery, 0.96% (1 of 104 cases) in general surgery, and 7.69% (1 of 13 cases) in urology. 4) The most frequently used ventilator was Bear II, followed by Benett MA-I. 5) The major causes of death in RICU were low cardiac output syndrome, sepsis, respiratory failure, and brain damage.
