Lipoid pneumonia is chronic, interstitial, proliferative inflammation resulting from aspiration of lipoid material. Mineral oil is a hydrocarbon that physicians often use to treat chronic constipation in children and adults. Mineral oil may not elicit a normal protective cough reflex and may impair mucociliary transport. We experienced a case of exogenous lipoid pneumonia caused by aspiration of mineral oil given as a laxatives confirmed by fiberoptic bronchoscopy with bronchoalveolar lavage and bronchial biopsy in a 9-month-old boy with chronic cough and radiologic evidence of parenchymal lung disease.We reported this case with a brief review of related literatures.

OBJECTIVE: To investigate the role of tendon reflex test in the diagnosis of diabetic peripheral neuropathy. METHOD: Patellar tendon reflex (PTR) and achilles tendon reflex (ATR) were recorded in forty six diabetic patients and thirty seven normal adults by delivering tendon taps with an electric reflex hammer. Forty six diabetic patients were divided into two groups based on nerve conduction study and diabetic neuropathy score: group 1 consisted of nineteen patients with peripheral neuropathy, group 2 consisted of twenty seven patients without peripheral neuropathy. Multiple regression equations using latency as a variable dependent on age and height were used and upper crossing of the 3 standard deviation level with regression on height and age was considered abnormal. RESULTS: Mean latencies of PTR and ATR were prolonged in the diabetic patients in comparison with the controls (p<0.01) and were prolonged in group 1 compared to group 2. In group 1, PTR was abnormal in 14 cases (sensitivity: 73.6%, specifity: 88%) and ATR was abnormal in 13 cases (sensitivity: 68.4%, specifity: 85.1%). In group 2, PTR was abnormal in 3 cases and ATR was abnormal in 4 cases. CONCLUSION: Tendon reflex test would be a valuable supplement to conventional nerve conduction studies for detection of diabetic peripheral neuropathy, especially in the proximal segment.

BACKGROUND: Perfusion scans are accurate predictors of postoperative lung function. There are few previous studies aimed at predicting the postoperative exercise capacity using the perfusion scanning and those that did reported contradictory results. METHOD: We prospectively studied the preoperative spirometric, exercise tests and perfusion scans from in 49 consecutive patients who were admitted to Inha University Hospital with surgically resectable lung cancer from Jan. 1998 to Jun. 1999 29 patients who had any condition affecting the lung function and exercise capacity, or refused a surgical resection or a follow-up study were excluded. Spirometric and exercise tests were performed 6 months after operation in 20 patients. RESULTS: The predicted postoperative FEV1, FVC and TLC correlated well with the following corresponding postoperative values : γs and p value, 0.809 and 0.000 for the FEV1 ; 0.895 and 0.000 for the FVC ; 0.741 and 0.006 for the TLC, respectively. The measured postoperative exercise values were slightly higher than the postoperative exercise values predicted, VO(2max) and Wr(max), were as 112% of VO(2max) predicted and 119% of WR(max) predicted. The change in FEV1, FVC and TLC had a weak correlation with the change in VO(2max) and WR(max). CONCLUSION: The perfusion scan was a useful tool for predicting the postoperative exercise capacity. However, they had a tendency to underestimate the exercise capacity, especially in the patients who had a pneumonectomy. A weak correlation between the change in lung function and exercise capacity was obseved.

BACKGROUND: Systemic hypertension produces varying degree of LVH which is associated with increased cardiovascular morbidiity. Previous studies have documented regression of LVH with various antihypertensives including calcium channel blockers, except diuretics and vasodilators. Recently echocadiographic assessment of the change of left ventricular mass(LVM) after antihyertensive therapy have been reported to offer prognostic cardiovascular information. The aim of this echocardiographic study is determining the influence of nicardipine, a calcium channel blocker, on the change of LVM in patients with essential hypertenison. METHODS: Left ventricular mass(LVM) and left ventricular mass index(LVMI) were measured by M-mode echocardiography in 15 patients with essential hypertension. Nicardipine, a calcium channel blocker, was administered for 6 months and two echocardiographies were done before and after administering, respectively. RESULTS: In the 15 patients treated for 6 months, systolic and diastolic pressure remained very significantly decreased compared with pressure before before therapy(135+/-15mmHg vs 168+/-26mmHg, and 86+/-7mmHg vs 105+/-16mmHg, both p<0.01). Concomitantly both LVM and LVMI decreased significantly(209+/-49g vs 235+/-71g, and 116+/-6g/m2 vs 131+/-38g/m2,both p<0.05). And no change was noted in left ventricular cavity size, demonstration that LVM reduction was due to regression of hypertrophy. CONCLUSION: This study showed that nicardipine produced a significant decrease in blood pressure, LVM, and LVMI over the 6 months period. And large and longterm controlled studies are needed for the clarification of the association between nicardipine and regression of LVH in hypertensive patients.

The worm development and egg laying pattern of Echinostoma hortense(Trematoda: Echinostomatidae) were studied in albino rats and the brief clinical course was observed in human volunteers. A total of 21 rats were infected with 20-69 metecercariae each and two humans were with 7 and 27 metacercariae, which were collected from loaches. For recovery of worms, the rats were sacrificed at irregular intervals from the 6th to 150th day after infection and the human volunteers were treated with praziquantel and purged with magnesium salt on the 26-27th day. The stools of the rats and humans were examined for the eggs. The results were as follows: The worm recovery rate from the rats was not affected by the increase of infection time but varied individually; 9.1-50.0% (31.1% in average). From humans, 14.3% and 37.0% (32.4% in average) of challenged were recovered. In the rats, it was revealed that the worms rapidly grew for the first 14 days to become 7.59 mm in average length and 1.17 mm in average width but the growth became much slower thereafer until the 150th day; 7.95 mm in length on the 21th day, 9.04 mm on the 28th day, 10.21 mm on the 49th day and 12.62 mm on the 150th day. During the early stage of infection, the growth of genital organs(male or female) was expressed as sigmoid curves whereas non-genital organs(such as suckers) was simply as straight lines. The prepatent period of this fluke was 10-12 days in the rats and 16-17 days in men. After the start of oviposition, the egg production by the worms remarkably increased, reached maximum on the 32-33th day, followed by decrease thereafter. The maximum value of E.P.G./worm was 390. The major subjective symptoms in human volunteers were abdominal pain and diarrhea during the early stage of infection. The results show that human is as susceptible as the rats to E. hortense infection and the amount of egg production in the rats is greatly affected by the age of worms.

Vascular disease of the spinal cord occurs less frequently than of the brain, and its incidence is not known. Case reports of spinal cord infarction are uncommon, especially ones with spontaneous causes. We experienced one case with a spontaneous spinal cord infarction in the territory of the Adamkiewicz artery. In this case, the clinical pictures were characterized by sudden onset of paraplegia, bilateral radicular pain, dissociated sensory loss below the level of infarction and sphincter dysfunction. Neuroradiological investigation and CSF analysis ruled out compressive or infectious lesions. Selective spinal angiography revealed an occlusion of the Adamkiewicz artery. The patient had a substantial recovery over a period of weeks with intensive rehabilitation treatments.

A slowly growing, non-chromogenic mycobacterial strain was isolated from sputum and bronchial lavage fluid samples of a patient presenting with productive cough, blood-tinged sputum, low-grade fever, and weakness. A positive acid-fast bacilli sputum smear result prompted the initiation of an anti-tuberculosis regimen. Multiplex real-time PCR showed a negative result for Mycobacterium tuberculosis complex and a positive result for nontuberculous mycobacteria. The DNA chip test confirmed this organism as a member of the genus Mycobacterium, but could not specify the species. Interestingly, the mycolic acid patterns obtained by HPLC nearly overlapped with those of M. simulans. The sequences of the Mycobacterium 16S rRNA gene and 16S-23S internal transcribed spacer region were unique and were found to have 100% similarity with those of M. riyadhense. After a review of the literature, we report this case as the first Korean case of M. riyadhense lung infection.

The purpose of this study was to isolate and characterize the Fusobacterium nucleatum (F. nucleatum) from subgingival plaque in Korean periodontitis patients. The subgingival plaque samples of periodontitis patient were collected with sterilized paper point. The paper point was put into reduced transfer medium and then immediately transferred to laboratory. The subgingival samples were diluted by 10,000 folds and plated on F. nucleatum-selective media agar plate. The plates were incubated at 37degrees C in an anaerobic chamber for 3 days. The violet-colored colonies were selected and subjected to further verification whether those are F. nucleatum or not. For further confirmation, 16S rRNA genes (rDNA) were cloned from each of bacterial clones and determined sequence of 16S rDNA. In this study, we found 17 distinct clinical isolates of F. nucleatum from subgingival plaque. The clinical isolates will be a useful in various studies in periodontology.
