BACKGROUND: This study was performed to evaluate the therapeutic effects of sympathetic block in management of reflex sympathetic dystrophy (RSD); renamed complex regional pain syndrome (CRPS) Type I, according to the duration of RSD, and to evaluate predictable factors responding to sympathetic block in patients suffering from RSD. METHODS: Prospectively designed this study was divided thirty patients with upper extremity RSD into three groups according to the duration of RSD; Group I (< or = 3 months), Group II (4 to 6 months) and Group III (>or = 7 months). All patients were received repeated stellate ganglion blocks (SGB) with 12 ml of 0.2% bupivacaine by paratracheal approach. We compared the therapeutic effects of SGB between the groups and the clinical signs on initial examination to receive the first SGB at pain clinic. RESULTS: Response rates to SGB were 84.6% in Group I, 62.5% in Group II and 44.4% in Group III. The early treatment less than 6 months was better prognosis (p<0.05). Presence of edema (p<0.001), temperature differences between both hands (hot>cold>no difference, p<0.001), and allodynia (p<0.05) were favorable prognostic factors responding to sympathetic block. Especially, warm skin and edema in RSD were near-perfect predictors of sympathetic blocks. CONCLUSIONS: We conclude that SGB is effective in management of upper extremity RSD, and the duration and the clinical signs of RSD are important to the prognosis and responsibility to sympathetic block. If patients suffering from RSD visit pain clinic before 6 months, and they have edematous warm hands with allodynia, majority of them will be improved from their pain after sympathetic block.

Since Lebert stated, in 1851, that fibroblastic and sarcomatous tumors of the intracranial cavity had different survival times, many neuropathologists tried to set up histopathological grading system predicting the prognosis of the tumor of the nervous system. Especially, the histological assessment of the aggressiveness of meningiomas has not always been useful in conforming the biological characteristics of these tumors, and the definition of malignancy is still subject to controversy. However, metastases from meningioma to remote sites have always been considered rarities. The authors experienced a case of metastatic meningioma, hemangiopericytic type, with a history of recurrence. A forty years old male patient received a craniotomy to remove a mass in right parasagittal region, in June 1981. He had suffered from Jacksonian type of seizure started from left foot throuth leg, thigh, and arm to face. During operation, a well defined mass was noted in left parasagittal region with cleavage plane. The tumor was completely removed with cauterization of invasion site. In microscopic examination, the mass had typical findings of hemangiopericytic type of meningioma. In September 1987, he received a repeat operation to remove a recurred tumor mass in vertex, at age of forty-six. The removed tumor revealed same histologic features as those seen in primary tumor. In January 1990, at age of forty-nine, he noted pain and tenderness on the right iliac crest and the left iliac tuberosity, Plain pelvis AP x-ray ad Pelvis CT scan revealed osteolytic expansile mass lesions involving both iliac bones, the body of second sacral vertebra, and the right superior ramus of the pelvic bone. An open biopsy of the iliac bone was performed. The microscopic findings of the bone lesion were same as reccruent lesion of the brain.

Pleomorphic adenoma presenting as primary lesion of the bronchus is very rarely encountered, and in our knowledge only 6 cases have been reported in the literature of the western world, and no case report has been published in Korea. Currently, we experienced a case of bronchial pleomorphic adenoma occuring in a 38 years old woman. On X-ray examination, hazy density in the right upper lobe and emphysematous change in the right lower lobe were noted. A right pneumonectomy was done under bronchoscopic diagnosis of bronchial adeoma. The pathologic examination of the present case showed a polypoid endobronchial tumor, 1.4 x 1.1 cm (with extraluminal portion, 2.2 x 1.7 cm) in the right upper bronchus. The microscopic examination revealed a pleomorphic adenoma showing same morphology as those found in the salivary gland. This case, therefore, was believed to be a genuine example of bronchial pleomorphic adenoma of salivary gland type. We compared this case with 6 cases in the literature.

Primitive neuroectodermal tumors (PNET) of the ovary are rare tumors with an exclusive or almost exclusive malignant neuroectodermal composition, and are generally regarded as a monodermal expression of an ovarian teratoma. The tumors are basically identical with the lesions of the same name occuring typically in the central nervous system of children. These tumors consist chiefly of undifferentiated small cells resembling neuroblasts. There are also mature, well- differentiated neuroectodermal cells, such as astrocytes and ependymal cells. We report a case of ovarian PNET with glial and neuroblastic differentiation and focal teratomatous foci of non-neural tissue in a 17-year-old female.

Hemimegalencephaly is an uncommon sporadic congenital malformation of the central nervous system characterized by enlargement of one cerebral hemisphere with cranial asymmetry, hemiparesis, epilepsy, and mental retardation. This report deals with a 12-month-old girl with intractable seizure and developmental delay, who revealed hemispheric asymmetry and enlarged right cerebral hemisphere. MRI scan revealed asymmetric enlargement of right cerebral hemisphere with lissencephaly and multifocal calcification. She underwent right frontal lobectomy and parietal cortical resection, but died of complication of surgery. Histological features included loss of cortical lamination, large atypical neurons, neuronal heterotopia, and astrocytosis with dystrophic calcification. The heterotopic neurons in the white matter were suggestive of aberrant neuronal migration.

This report describes a primary malignant melanoma which developed in the anus, as documented by light microscopy and immunohistochemistry. A 53-year-old woman had a 4 month history of a protruding mass in the anal canal. The mass was located in the squamo-columnar junction of the anal canal, measuring 5.0x4.5 cm. Its cut surface was dark brown and poorly circumscribed. The histologic appearance was characterized by epithelioid or spindle cells with prominant nucleoli and frequent atypical mitosis. Melanin pigments were strongly seen in Fontana-Masson stain. Immunoreactivity revealed that the cytoplasm of tumor cells was strongly positive with antibody directed against S-100 protein, vimentin and it was focally positive with neuron specific enolase.

Serovars of 22 leptospiral field isolates from rats trapped in Korea were identified by cross-agglutinin absorption test (CAAT). Genomic characteristics of 7 selected isolates and 6 antigenically closely related reference serovars of lai, yeonchon, birkini, gem, mwogolo, and canicola were differentiated by arbitrarily primed PCR (AP-PCR) and southern blot hybridization using 16S rRNA gene probe from Borrelia burgdorferi. Among the 22 isolates, 21 strains were identified as serovar lai by CAAT, while the serological reactivity of NR13 did not accord with that of serovar lai. Results of AP-PCR using primers RSP, KF and PB-1 were in general agreement with those obtained by serological identification, and all 7 isolates including NR13 showed the same profile with serovar lai or yeonchon. In the southern blot hybridization with 16S rRNA gene probe, the isolates were divided into two ribotype groups when HindIII and BamHI digests were employed: isolates NR4, NR13, and serovar lai showed the same profile, and isolates JR34, JR57, KR48, JR77, and JR82 were classified as the another ribotype group. Isolate NR13 and serovar yeonchon, which were isolated in Korea and showed serological differences with serovar lai, were indistinguishable from serovar lai in this DNA study using AP-PCR and ribotyping. These results demonstrate that Korean leptospiral isolates were closely related in DNA level, and ribotyping would be useful for subgrouping of field isolates.

So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells having pre- dominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei, The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchioloalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.
