BACKGROUND: There has been reports which suggest that non-specific symptom of patients with mitral valve prolapse is associated with autonomic dysfunction. METHODS: To assess autonomic dysfunction of patients, we examined five cardiovascular reflex tests in 25 asymptomatic MVP patients(identified as MVP group), 25 symptomatic MVP patients(identified as MVP syndrome group) and 25 control group. RESULTS: In the five cardiovascular autonomic function tests, abnormalities of Valsalva ratio were detected in 1(4%) control group, 7(28%) MVP group, 9(36%) MVP syndrome group, heart rate response to deep breathing in 0(0%), 2(8%), 4(16%) respectively, immediate heart rate response to standing in 0(0%), 2(7.4%), 2(8%) respectively and in postural hypotension, there were no abnormal group. Abnormalities of blood pressure response to sustained handgrip were only detected in 2(8%) MVP syndrom group. According to the five categories of cardiovascular autonomic functon tests, normal in 24(96%) and early damage in 1(4%) were detected in control group. In the MVP group, normal 17(68%), early damage 6(24%) and definite damage 2(8%) were noted. In the MVP syndrome group, normal 9(36%), early damage 13(52%), definite damage 1(4%) and combined damage 2(8%) were detected. In case of heart rate response to deep breathing, we found significant differences between control and MVP syndrome group(p=0.043), and between MVP and MVP syndrome group(p=0.0043). In case of heart rate response to standing, between control and MVP syndrome group(p=0.0009), between MVP and MVP syndrome group(p=0.001), the differences were noted. In case of blood pressure response to standing, between control group and MVP group(p=0.0019), between MVP and MVP syndrome group(p=0.0075), we found significant differences. Resulting from our study, heart rate response to deep breathing and standing, blood pressure response to standing were of considerable value in assessing the autonomic dysfunction of patients with mitral valve proapse. CONCLUSION: We found autonomic dysfunction in addition to increased autonomic tone and responsiveness which have been already known previously in mitral valve prolapse. And autonomic dysfunction was more severe in symptomatic patients with mitral valve prolapse than asymptomatic ones.

PURPOSE: This study was performed to investigate the ultrastructural changes of the optic nerve after intravitreal injection of herpes simplex virus-1. METHODS: Herpes simplex virus was separated from the culture media after observing the cytopathic effect on cultured vero cells. Viruses were then injected on the optic nerve head of 21 rabbit eyes. Eyes were enucleated at 1, 2, 3, 5, 7, 10, and 14 days after injection of herpes simplex virus and examined under the electron microscope. RESULTS: The intranuclear inclusion body was noted in eyes examined at 2 days after injection. The histopathological changes were perivascular infiltration of inflammatory cells, cytoskeletal degeneration of large diameter of myelinated nerve, demyelination of axonal nerve fiber, and the accumulation of mitochondria within axonal nerve fiber. CONCLUSIONS: These results suggest that optic neuritis may be induced by herpes simplex virus. The accumulation of mitochondria may be related to the interruption of the axonal transport through the axonal nerve fibers of optic nerve.

Giant cell tumor (GCT) occurs very unusually in the rib (less than 1% of GCT). We present the cytologic features of GCT of the rib. It showed multiple cellular clusters composed of characteristic, benign looking osteoclast-like multinucleated giant cells and fibroblast-like mononuclear cells. The multinucleated giant cells contained numerous nuclei (average, 30 to 40 per cell, which were closely packed. The nuclei in giant cells were remarkably uniform and round to oval. The mononuclear, neoplastic stromal cells were elongated and spindle-shaped, There was no cytologically malignant portion in the tumor.

Gastrointestinal cytomegalovirus(CMV) infection in adults is observed as a part of a generalized or localized infection in patients who are immunocompromized. We report a case of CMV infection of the small intestine. The patient is a 34 year-old woman who has complained of palpable purpura in the lower extremities and buttocks, and arthralgia of large joints. The skin biopsy showed fibrinoid necrosis and neutrophils with leukocytoclasis, which findings are compatible with hypersensitivity angiitis. The patient received steroid and cyclophosphamide. During the follow-up period, generalized edema and bloody stool were detected. Resected specimen of small bowel has multiple aphthous ulcer. Microscopically, cytomegalic cells are observed along the endothelial cells and mesenchymal cells. In situ hybridization using DNA probes against CMV revealed positive staining in the cytomegalic inclusions in vascular endothelial and mesenchymal cells.

The recently proposed Bethesda system for cervical/vaginal cytology has made a standardization related to "atypia". In cellular changes due to inflammation or repair, the word "benign cellular change" has been suggested as a substitute for atypia. Terminology related to atypical cells may become standardized, but the cytologic criteria has not been well defined yet. We evaluated 160 cases of atypical squamous cells of undetermined significance(ASCUS) by the Bethesda System(TBS). Among 30,428 cases screened, a cytologic diagnosis of ASCUS was made in 498 cases(1.6%) and 160 cases were histologically verified. ASCUS was diagnosed based on nuclear enlargement and nonclassical signs of condyloma. The results are as follows: One hundred and twenty three cases(76.9%) revealed chronic cervicitis. Thirty seven cases(23.1%) demonstrated squamous intraepithelial lesion. Among intraepithelial lesions, condyloma and mild dysplasia were 28 cases(75.7%). Moderate and severe dysplasia were 5 cases(13.5%) and 4 cases(10.8%), respectively. It is concluded that patients with ASCUS should be colposcopically examined.

Malignant fibrous histiocytoma is the most common soft tissue sarcoma of late adult life, but it is rare in the pleura. We recently experienced a case of cytology of malignant fibrous histiocytoma in pleural fluid. The smear revealed histiocytic malignant cells, spindle malignant cells and inflammatory cells. The histiocytic cells showed abundant, pale cytoplasm and ovoid, irregular, eccentrically-placed nuclei. The spindle cells showed elongated nuclei. Intercellular collagen was also present.

PURPOSE: To analyze the clinical features of patients with exodeviation of more than 15 prism diopters (PDs) within one month and with orthophoria over three years after surgical correction of intermittent exotropia. METHODS: The early recurrence group consisted of patients with a final distance and near exodeviation more than 15PDs within one month after surgical correction of intermittent exotropia. The surgical success group was defined as patients with orthophoria over three years after surgical correction of intermittent exotropia. Sex, age at onset and surgery, office control status, refraction status, A-V pattern, preoperative and postoperative angles of ocular deviation, binocular sensory status, and the presence of diplopia on postoperative one day were retrospectively investigated and compared between these two groups. RESULTS: Out of a total of 68 patients, early recurrence occurred in 33 patients, and success was achieved in 35 patients. Factors including sex, age at onset and surgery, office control status, and diplopia on postoperative one day did not differ between the two groups. Preoperative near-angles of ocular deviation, A-V pattern of strabismus, preoperative stereopsis, and the range of postoperative overcorrection contributed to early recurrence. CONCLUSIONS: Factors related to early recurrence were larger preoperative near-angles of ocular deviation, presence of A-V pattern, poor preoperative stereopsis, and a smaller amount of overcorrection on postoperative day 1.

BACKGROUND: Mitral stenosis is charcterized by decrease in mitral valve area anatomically and increase in transmitral pressure gradient hemodynamically. And these changes have been used to quantify the severity of mitral stenosis clinically. To evaluate the clinical usefulness of mitral valve resistance as a hemodynamic parameter in patients with mitral stenosis, we compared the mitral valve resistance to the clinical status of the patient with mitral stenosis, the other hemodynamic parameters and static parameter. METHODS: We analyzed and reviewed the data obtained from the consecutive 27 patients with mitral stenosis(7 male, 20 female : mean age 38+/-9 years) who had been underwent percutaneous mitral valvuloplasty(PMV). RESULTS: Befor PMV, the mitral valve resistance was significantly correlated with exercise capacity on treadmill test(r=-0.37, p<0.05), mitral valve area(r=-0.72, p<0.01), transmitral mean pressure gradient(r=0.83, p<0.01),not with cardiac output, mixed venous oxygen saturation. After PMV, the mitral valve resistance was significantly correlated with mitral valve area (r=-0.72, p<0.01), transmitral mean pressure gradient(r=0.90, p<0.01).According to the results summerizing and comparing the values of before and after percutaneous mitral valvuloplasty, the mitral valve resistance had good relationship with preexisting paramerters of severity such as mitral valve area(r=-0.82, p<0.01), transmitral mean pressure gradient (r=0.92, p<0.01). CONCLUSION: This results indicate that the mitral valve resistance is a useful hemodynamic parameter in patients with mitral valve stenosis and reflects the exercise capacity during the treadmill test which was the objective parameter of practical and clinical status of the patient well than the other hemodynamic parameters in case of remarkably reduced transmitral valve blood flow due to severe mitral valve stenosis, because the degree of change in the mitral valve resistance in relagion to the degree of change in transmitral valve blood flow is relatively more constant than the other hemodynamic parameters.
