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.

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.

BACKGROUND: High blood pressure is prevalent in obesity and diabetes, especially noninsulin dependent diabetes mellitus, and both conditions are insulin resistant state. METHOD: To test whether resistance to insulin-stimulated glucose uptake and hyperinsulinemia are involved in the pochogenesis of hypertension, author measured glucose, insulin and C-Peptide reponse after oral glucose loading in 52 cases of essential hypertension and 62 cases of normal controls who had been admitted to the ward of internal medicine, Pusan National University Hospita. RESULTS: Basal plasma glucose, insulin and C-Peptide levels in control subjects were 92.1+/-36.8mg/dl, 8.7+/-5.5microu/ml and 2.2+/-1.8ng/ml and in hypertensive subjects were 95.7+/-32.6mg/dl, 12.2+/-5.3microu/ml and 2.9+/-1.6ng/ml. The basal insulin level was markedly higher than tat of control subjets (p<0.05). The basal glucose and C-Peptide levels in hypertensive patioents were higher than controls but statistically not significant. Plasma glucose levels in time course after glucose load in hypertensive patients showed significantly higher levels in 60,90minutes than controls. Plasma insulin levels in hypertensives in 90 minutes were significantly higher. The C-Peptide levels in hypertensives showed significantly higher in each times 30,60,90,120 minutes than controls. In hypertensive patients, body weight, blood pressure levels and duration of hypertension were not significantly correlated with responses of glucose, insalin and c-peptioce. Hypertensive patients aboce the age of 50 showed significantly higher glucose levels in 60,90,120 minutes than under age of 50. CONCLUSION: These results indicate some tendency of disturbed glucose turnover or insulin-resistant state in essential hypertension. This metabolic disturbance in essential hypertension should be considered in the management of hypertensive patients.

Two unique cases of delayed nerve root herniation and entrapment into the pseudomeningocele through an unrepaired dural laceration at lumbar laminectomy were reported. Both patients presented with recurred radiculopathy, 3 and 6 years after first operation respectively. Lumbar myelography showed an extradural pseudomeningocele pouch in case 1 while showing no abnormality in case 2. Lumbar MRI in case 1 showed tangled herniated nerve root in the pouch of pseudomeningocele. Lumbar myelographic CT of case 2 showd delayed partial filling of the pseudomeningocele pouch only. Herniation through dural defect and entrapment of nerve root in the pseudomeningocele was nosted during surgery. Surgical correction of the herniated nerve root and dural repair was performed and this correction completely relieved the pain in both patients. These cases demonstrate even a small tear in the spinal dura during laminectomies requires surgical closure to prevent late nerve root herniation. Finally, the possible mechanism of this condition was also discussed.

Despite the modern advance in effective chemotherapy, gastrointestinal tuberculosis is considered to be relatively frequent in developing countries. The ileocecal region is the most common site of intestinal tuberculosis and duodenal involvement is rare. The isolated duodenal tuberculosis are reported 9 cases in Korea. The symptoms and signs of gastrointestinal tuberculosis are nonspecific and vague. In the absence of pulmonary tuberculosis, the diagnosis may be difficult. Pain and vomiting are common symptoms of duodenal tuberculosis. Patients may present with upper gastrointestinal bleeding. Therefore, tuberculosis should be considered in the differential diagnosis of gastrointestinal bleeding. We herein report a case of duodenal tuberculosis presenting as hematemesis and necessitating hospitalization. After anti-tuberculosis therapy, we have confirmed the healing of the lesion by the follow-up endoscopy, and review the current literature.

BACKGROUND: Mantle cell lymphoma/leukemia (MCL) is a distinctive disease entity that has been characterized by specific histopathologic, immunologic, and cytogenetic features. The characteristic cytogenetic abnormality of MCL is t(11;14)(q13;q32), that results in cyclin D1 overexpression. We have experienced 12 MCL cases with bone marrow involvement that were lacking evidence of t(11;14). We tried to review the cases. METHODS: We reviewed the bone marrow findings, immunophenotypic, cytogenetic studies including fluorescent in situ hybridization (FISH) analysis using IGH/CCND1 probes and medical records of 12 patients that were diagnosed with MCL based on immunophenotypic results during the period 1997 to 2001. RESULTS: The patients had a median age of 63 (50-70) years with male-to-female ratio of 3:1. All patients showed hepatosplenomegaly with varying degrees of peripheral blood involvement (2-93%), and lymphocytosis was found in 7 cases. Other presenting features were palpable lymph nodes (83%) and B symptoms (25%). The malignant cells were quite heterogenous in morphology from centrocytic to blastic variants. Most cases showed typical immunophenotypes-expression of CD19, bright CD20, FMC7, CD5 and bright-light chains with negative CD23. Immunohistochemical staining with cyclin D1 on marrow biopsies showed mostly negative results. Among the eleven cases in which cytogenetic studies were possible, four cases showed complex karyotypes, and three that involved 14q32. Strikingly, no one showed t(11;14) in G-banding analysis and only 2 cases showed IGH/CCND1 rearrangement by FISH. CONCLUSTIONS: Most MCL cases with typical immunophenotypic findings did not show evidence of specific cytogenetic features. Although further workups for molecular pathogenesis and clinical follow-up of the above cases need to be done, we suggest a new disease entity, t(11;14)-negative MCL.

BACKGROUND/AIMS: The Follicular Lymphoma International Prognostic Index (FLIPI) and FLIPI2 are well-known prognostic models for patients with follicular lymphoma (FL). However, their prognostic relevance has not been examined before in Korean patients with FL. METHODS: We reviewed clinical and laboratory information from our database of patients between 1995 and 2012. In total, 125 patients were stratified in three categories according to FLIPI or FLIPI2 scores: low-, intermediate-, and high-risk groups. We compared FLIPI and FLIPI2 in terms of progression-free survival (PFS) and overall survival (OS). RESULTS: Among the 125 patients, the prognostic value of FLIPI and FLIPI2 was evaluated in 73 patients who fulfilled the criteria of both prognostic models. Risk stratification by FLIPI and FLIPI2 showed significant differences in unfavorable parameters among each risk group, particularly between low- and intermediate-risk groups. The high-risk group b was significantly associated with poor PFS on both FLIPI and FLIPI2 (p < 0.05). However, the OS was significantly different only in the risk groups determined by FLIPI2 (p = 0.042). In a subgroup analysis of patients who received rituximab-containing chemotherapy, the risk stratification of both prognostic models showed a significant impact on PFS, especially in the low-risk group. CONCLUSIONS: FLIPI and FLIPI2 are appropriate prognostic models in Korean FL patients, especially for discriminating low-risk patients from intermediate- and high-risk groups.

Primary bladder amyloidosis is a rare disease causing hematuria which is difficult to be differenciated from bladder cancer at cystoscope. We report a case of primary bladder amyloidosis who was diagnosed at other procedure for distal ureteral stone failed in repeated ESWL disintegration. Transurethral resection of bladder mass and the pathologic results revealed amyloidosis. The systemic studies for the detection of the site of other amyloidosis were failed to get positive result. There were massive hematuria after a few hours later from the transurethral resection of the bladder mass and the bleeding was controlled with 1% alum bladder irrigation. The patient is followed regularly for recurrent amyloidosis.
