As gastroduodenoscopy performed more frequently, case reports of human echinostomiasis are increasing in Korea. A Korean woman presented at a local clinic with complaints of abdominal pain and discomfort that had persisted for 2 weeks. Under gastroduodenoscopy, two motile flukes were found attached on the duodenal bulb, and retrieved with endoscopic forceps. She had history of eating raw frog meat. The two flukes were identified as Echinostoma hortense by egg morphology, 27 collar spines with 4 end-group spines, and surface ultrastructural characters. This report may prove frogs to be a source of human echinostome infections.

To validate ventricular diastolic phase parameters of reconstructed transmitral flow rate curve by M-mode, 2-dimensional and pulsed Doppler Echocardiography, these parameters were compared with same parameters by left ventriculography. The study population was 22 patients who received both coronary arteriography and echocardiographic examination. Transmitral flow rate curve and left ventricular filling volume curve were reconstructed from transmitral flow velocity curve by pulsed Doppler, mitral annulus diameter by two diameter by two dimensional and diastolic motion of both mitral leafltes by M-mode echocardiography. From left ventriculography, left ventricular filling volume curve and transmitral flow rate curve were made using area-length method by Sandler and Dodge. From trasmitral flow fraction, 1/2 diastolic time filling fraction, normalized peak filling volume, 1/3 diastolic time filling fraction, 1/2 diastolic time fraction, normalized peak early filling rate and ratio of early to late peak filling rate were measured. Correlation between same parameters derived from echocardiography and left ventriculography were observed. 1) Total diastolic filling volume:correlation coefficient r=0.47, P<0.05. 2) 1/3 diastolic time filling fraction:correlation coefficient r=0.90, P<0.001. 3) 1/2 diastolic time filling fraction:correlation coefficient r=0.80, P<0.001. 4) Normalized peak early filling rate:correlation coefficient r=0.57, P<0.01. 5) Ratio of early to late peak filling rate:correlation coefficient r=0.85, P<0.001. Therefore, left ventricular diastolic phase parameters of reconstructed transmitral flow rate curve using, M-mode, 2-dimensional and pulsed Doppler echocardiography seems to be useful for the noninvasive evaluation of the left ventricular diastolic function.

To evaluate the disturbed left ventricular diastolic filling by pulsed Doppler echocardiography in patients with ischemic heart disease who have normal systolic function, 117 subjects (50 angina patients with, 39 myocardial infarction patients with, 28 control subjects without significant coronary arterial narrowing) underwent echocardiographic examination one day before coronary arteriography. Beside analyzing trasmitral flow velocity curve, reconstruction and quantitative analysis of left ventricular filling rate and filling volume curves were made from Doppler trasmitral flow velocity curve, 2-Dimensional mitral annulus diameter and M-Mode mitral valve motion. From reconstructed left ventricular filling rate, filling fraction during early rapid filling or half diastolic rate, ratio of early to atrial peak filling rate, filling fraction during early rapid filling or half diastolic period and diastolic time interval(esp. T1/2 from peak early filling rate to its half valve)were measured. Angina and myocardial infarction group had significantly lower normalized peak early filling rate(4.9+/-0.6, 4.8+/-1.2 vs 6.0+/-1.1 DFV/sec, P<0.005), ratio of early to atrial peak filling rate(103.6+/-29. 4120.6+/-3.5 VS 175.5+/-55.0%, P<0.005), filling fraction during early diastolic period(46.2+/-5.0, 44.4+/-12.6 VS 54.3+/-6.8%, P<0.005) and filling fraction during half diastolic period(56.3+/-5.8, 55.4+/-14.1 VS 66.6+/-7.7%, P<0.005) than those of control group. Angina and myocardial infarction group had significantly higher normalized peak atrial filling rate(4.9+/-1.4, 5.0+/-2.0 VS 3.5+/-0.9 DFV/sec, P<0.005), prologed normalized T1/2 (12.5+/-3.0, 12.0+/-4.0 VS 9.8+/-2.2%, P<0.005) and delayed isovolumic relaxation time(81.7+/-7.8, 95.0+/-13.6 VS 74.3+/-6.9msec, P<0.005) than those of control group. Affecting factors to pseudonormalize left ventricular filling rate and filling volume curves in myocardial infarction group were mitral regurgitation, left ventricular aneurysm and severe impairment of systolic function. In 13 angina group patients who had undergone coronary angioplasty, no difference were found in any noninvasive diastolic filling parameters before and immediately(24 hours and 5 days) after the procedure. Thus, abnormal patterns of left ventricular filling occur in patients with ischemic heart disease and near normal global systolic function. The decreased peak early filling rate and early filling fraction occuring during rapid filling and the increased peak atrial filling rate occuring in late diastolic suggest that the patients with ischemic heart disease have impaired early diastolic filling. These diastolic filling abnormalities are unimproved 24 hour and 5 days after succesful coronary angioplasty. These diastolic filling parameters from left ventricular filling rate and filling volume curves provide useful noninvastive hemodynamic indices for assessment of left ventricular diastolic filling in patients with ischemic heart disease.

Despite advances in imaging and antibiotic treatment, brain abscess is still encountered occasionally and is one of the most significant life-threatening complications of otologic disease. Nowadays, mortality rates of up to 10 percent have been reported. Brain abscesses are developed up to 0.5 percent of cases of acute otitis media and 3 percent of cases of chronic suppurative otitis media. In this case, underlying middle ear pathology showed chronic otitis media with cholesteatoma. Successful management of otogenic brain abscess still includes medical and surgical treatment. Initial surgical treatment of abscess is very controversial today. Some authors prefer the surgical excision of brain abscess prior to the management of temporal bone, yet other authors prefer the surgery of temporal bone prior to the management of brain abscess. Although an enterococcus is a significant cause of human infections outside of the central nervous system but, enterococcal infections involving the central nervous system are uncommon clinical entities. Because of the relatively small number of individuals who develop brain abscess or meningitis due to an enterococcus, an appropriate therapy has not been well defined. We report a case of enterococcal otogenic brain abscess which was treated successfully using antibiotics, immediate radical mastoidectomy and later stereotactic abscess drainage with a review of literatures.

Background: To test the hypothesis that Galphas gene mutation may suppress the expression of TRH-R gene, we investigated whether hTRH-R gene expression is lower in human GH-secreting pituitary adenomas with Galphas mutation than in tumors without the mutation. Method: TRH-induced paradoxical response of GH was observed in 8 acromegalic patients. The mutation of gene was identified by direct sequencing of the genomic DNA prepared from GH-secreting pituitary adenomas. The expression of hTRHT mRNA was quantitated by RT-PCR. Results: The transcript of hTRH-R gene was detected in 6 of 8(75%) tumors. Three of these(50%) showed the paradoxical GH response to TRH and the other three patients did not show the response. The relative expression of hTRH-R mRNA in the tumors from patients with the paradoxical response of GH to TRH did not differ from that in the tumors from patients without the paradoxical response. Direct PCR sequencing of Galphas disclosed a mutant allele and a normal allele only at codon 201 in 4 of 8 tumors. The paradoxical response to TRH was observed in 2 of 4 patients without the mutation, and 2 of 4 patients with the mutation. The hTRH-R gene expression of pituitary adenomas did not differ between the tumors without the mutation and those with mutation. Conclusion: This study suggests that the expression of TRH-R gene is not likely to be a main determinant for the paradoxical response of GH to TRH, and that Galphas mutation does not seem to suppress the gene expression of TRH-R in GH secreting adenoma.

IgA nephropathy is the most common form of glomerulonephritis characterized by deposit of IgA on mesangium. We experienced an elderly patient who was admitted for generalized edema, and diagnosed IgA nephropathy and early gastric cancer concomittantly. It has been reported that the incidence of nephrotic syndrome combined with malignancy increases with aging. Moreover, close relationship between IgA nephropathy and malignancy has been reported especially in the elderly patient. So, active investigations for possible malignancy are required in case of elderly patient with IgA nephropathy. In this case, we found improved proteinuria and hematuria of the patient after tumor resection during following up. This case suggest causal association between early gastric cancer and IgA nephropathy clinically.
