We observed a case of tuberculosis cutis orificialis, which occurred in 50 year-old man. He had been suffered from single markedly inflamed, erythematous painful ulcer, covered by dirty brown pseudomembranous material, around anus for 3 months. The laboratory findings (CBC, routine urinalysis, stool ova and parasite with occult blood) are within normal limits except elevated ESR (52mm/hr.). Staphyloeoccus aureus and proteus are observed on wound culture, and many AFB are seen on scrapings of wound but not on sputum for 3 times. Unfortunately culture was not done. Tuberculin skin test revealed strong reaction (36mm/hr.). Chest PA and small bowel series showed far advanced pulmonary tuberculosis and intestinal tuberculosis on ileocecal area. But the findings of upper gastro-intestinal series and barium enema are within normal limits. Histopathologic findings of skin lesion showed tuberculous and tuberculoid granuloma in the deep dermis and subcutaneous tissue.

Objective To study the microsurgical and anatomic structures of brachial plexus roots and vertebral canal to find the best approaches for reimplantation of avulsed brachial plexus ventral roots into the spinal cord.Methods On nineteen cervicothoracic spine specimens,the brachial plexus nerves were exposed along to intervertebral foramen,and the spinal cord and brachial plexus roots were exposed by excising the vertebral arch and sectioning the spinal dura mater.The anatomy of brachial plexus roots and vertebrae,and the relative positions of spinal cord segments to vertebral discs were measured and observed.Results The relative positions of spinal cord segments to vertebral discs are:C5-7 spinal cord segments face C3,4,C4,5 and C5,6 vertebral discs;and C8 and T1 spinal cord segments face C6 and C7 vertebrae.Based on the anatomic finding,four approaches were found out: the lateroventral approach,the lateral approach by enlarging intervertebral foramen,the laterodorsal approach and the lateral and dorsal combined approach.Conclusions The brachial plexus ventral roots can be best reimplanted into the spinal cord by the lateroventral approach and the lateral approach.Although the laterodorsal approach and the lateral and dorsal combined approach are not the best,they are less difficuh and dangerous.

Objective To assess the clinical value of MSCT in diagnosing the overcrowding of osteal posterior cranial fossa (PCF) in adults.Methods MSCT images of a cohort of 52 adult patients with foramen magnum osteal malformation confirmed by surgery (diseased group), and 100 healthy adults (control group) were retrospectively reviewed.Images post-processing techniques included multi-planer reformation (MPR) and volume rendering (VR).The posterior cranial fossa volume (PCFV), posterior cranial fossa height (PCFH), clivus length (CL), clivus gradient (CG), supraocciput length (SL), and anteroposterior diameter of the foramen magnum (FMD) were measured on sagittal images in 52 patients and 100 normal adults.Independent-sample student's t test was used to compare the differences between patients and normal adults.Results The results of PCFV, PCFH, CL, SL,FMD and CG, male of control group were (168.2 ±12.3) cm~3, (38.2 ±1.2), (47.1 ±2.8), (41.1 ±1.8), (36.6 ±4.9) mm, (51.5±3.6)°, female of control group were (157.5 ±10.2) cm~3, (36.5 ±1.4), (46.2 ±2.2), (39.7 ±1.3), (35.2 ±3.8), (49.6±3.1)° ;diseased group were (128.7 ±11.7) cm~3, (30.6 ±1.9), (36.2 ±1.4), (37.3 ±0.9), (33.9 ±3.5)mm, (44.5 ±2.8)° .There was significant sex difference in PCFV, PCFH, CL, SL and CG in control group (t =4.70, 6.44, 4.84, 4.43 and 2.81 respectively, P<0.01), but FMD was not significant(t=1.97,P>0.05); the results of PCFV, PCFH, CL, CG and SL were significant different between diseased group and male of control group (t=16.62, 24.04, 25.01, 14.17 and 10.99 respectively,P<0.01) ; the results of PCFV, PCFH, CL, CG and SL were significant different between diseased group and female of control group (t=13.23, 17.80, 27.50, 11.67 and 8.73 respectively,P<0.01) ;but there were no significant differences of FMD between diseased group and control group, both male and female (t=2.96,2.07, P> 0.05).Conclusions The overcrowding of PCF can be accurately measured by MCST.As a routine preoperative examination, MSCT is helpful in the therapeutic selection and the anatomic and pathologic study of PCF.

Hemorrhagic fever with renal syndrome (HIFRS), scrub typhus, murine typhus and leptospirosis have been the principal acute febrile diseases in Korea. To evaluate the seroepidemiologic patterns of acute febrile illness, sera collected from 2,423 patients in 1996 were examined for antibodies against Hantaan virus, Orientia tsutsugamushi, Rickettsia typhi, and Borrelia burgdorferi by indirect immunofluorescent antibody technique (IFA) and macroscopic agglutination test for Leptospira interogans. Seropositive cases against O. tsutsugamushi, Rickettsia typhi, Leptispira interogans and Hantaan virus were 192 (7.9%), 193 (8.0%), 12 (0.5%) and 324 (13.4%), respectively. Male was more affected in HFRS and murine typhus contrasting to scrub typhus and leptospirosis in female. Most positive cases occurred during October and November for scrub typhus, and during November and December for HFRS. These results showed similar patterns with previous epidemical data for recent couple of years, and possibly implied no significant changes occurred in ecologic situations for acute febrile diseases in Korea.

BACKGROUND:It is so difficult to have aortic valve replacement with smal aortic annulus. Improper treatment may lead to patients with valvular mismatch phenomenon, and thus make left ventricular outflow tract obstruction, increase transvalvular pressures, cause cardiac hypertrophy secondary to increased left ventricular afterload and even congestive heart failure.
OBJECTIVE:To summarize the treatment strategy for preventing valvular mismatch phenomenon caused by smal aortic annulus after aortic valve replacement.
METHODS:Eighty-five patients with smal aortic annulus underwent aortic valve replacement surgery. 19 mm SJM Regent valve was applied to the patients with orifice diameter>17 ≤ 19 mm;to the adult patients with orifice diameter ≤ 17 mm, we performed bovine pericardial patch enlargement of the smal aortic annulus and valve replacement using 19 mm SJM Regent valve. For those with orifice diameter>19 ≤ 21 mm, we selected 21 mm Hancock II ultra biological valve for valve replacement. Effective orifice area index, left ventricular mass index, inter-ventricular septal thickness, left ventricular wal thickness, trans-valvular peak velocity, the pressure difference across the valve and trans-valvular mean pressure were measured through echocardiography. After discharge, patients were fol owed up in out-patient clinic and evaluated regularly by echocardiography.
RESULTS AND CONCLUSION:There were no early deaths after operation and al cases were cured and discharged. Fol ow-up time was between 6 months and 3 years. The main complications included low cardiac output syndrome in two cases, reoperation due to bleeding in one case, and ventilator dependence in two cases. No cases occurred in cerebral complications such as cerebral hemorrhage or cerebral thrombosis, and no valvular dysfunction or card flap appeared. There was no bovine pericardium tearing, thrombosis, calcification, tumor-like bulge, infection or immune reactions. A total of 81 cases were fol owed up and the fol ow-up rate was 95%(81/85). There were NYHA class grade I in 65 cases, and grade II in 16 cases. Peak velocity across the aortic valve and the mean pressure were significantly decreased, effective orifice area index increased significantly, left ventricular mass index, left ventricular wal thickness and the thickness of the inter-ventricular septum were significantly reduced compared with pre-operation, and no valvular mismatch phenomenon occurred. Compared 21 mm Hancock II ultra biological valve with 21 mm SJM Regent group, the former got a better peak velocity and mean trans-valvular pressure, and better left ventricular remodeling index. Body weight and body surface area were significantly increased in 19 mm Regent valve group after operation. The results suggest that individualized treatment strategies should be taken to prevent the occurrence of postoperative valvular mismatch phenomenon for patients with smal aortic annulus.

AIM: To observe the inhibition of c-Met inhibitor on proliferation of lens epithelial cells (LECs).METHODS: Human's LECs were cultured and hepatocyte growth factor (HGF) and K252a were added to second passage of cells supplied with Dulbecco's modified eagle's medium (DMEM). MTT assay was used to examine the proliferation of LECs, and Western-blot was used to detect the expression change of Bcl-2 and Caspase-3.RESULTS: The photodensity (A) of HGF (50nmol/L) + K252a (30nmol/L) was not significantly different from that of DMEM control (P＞0.05). The expression of Bcl-2 and Caspase-3 were not significantly different from that in the control group.CONCLUSION: K252a, the inhibitor of c-Met, can effectively inhibit the proliferation of LECs.
