Using the FTA-ABS complernent test, 32 skin speciruens from 27 patients with primary and secondary syphilis and a stomach specimen from a patient with suspected gastric syphilis which were confirmed by clinical history, physical examination, VDRL, FTA-ABS, and 19S(IgM)-FTA test, were tested. The following results were obtained. 1. In the darkfield examination, 7 of the 9 specimens(78%) were positive and in the FTA-ABS complernent test, 20 of the 33 specimens(61%) were positive. 2. The ratio of agreement between the darkfield examination and the FTA-ABS complement test was 89%. 3. In the chancres, macular syphilids, and condyloma lata, T. pallida were diffusely scattered in the epidermis, dermoepidermal junction, connective tiasue, and vascular walls, whereas in the papular syphilid T. pallida were mainly aggregated in the the epidermis, dermoepidermal junction, papillary dermis as well as the blood vessel walls in the papillary dermis. From these results, the FTA-ABS complement test can be considered to be a useful method for both the diagnosis and research of syphilis. It is especially helpful in cases where serological or histopathological study can not confirrn the diagnosis as when internal organs are involved.

Fity-four patients with head and neck cancers were prospectively examined with the CT to determine its valuein staging cervical lymph nodes metastases and to compare with the clinical staging. The CT staging agreed withthe clinical staging in 61%(33/54), upgraded the clinical staging in 22%(12/54) and downgraded in 17%(9/54). Thepost-surgical confirmation was made in only 11 patients, The possible causes of disagreement between the CT andthe clinical staging, and the diagnostic value of the CT in the evaluation of the cervical nodes metastases werediscussed.

The Graf system has supposed advantages with its flexible nature, as compared with rigid fixation. But there have been no reports about effects in the adjacent motion segment after soft stabilization. The purpose of this study was to evaluate the radiologic changes occuring in the adjacent segments of the Graf system and to assess its ability stabilizing the lumbar spine. A retrospective review of radiographs and medical records was undertaken in 32 cases who had been treated with the Graf system in degenerative lumbar spinal disorders. The average age at operation was 52.5 years and the average follow up period was 49.6 months. The results of this study were as follows: clinical assesments based on the Kirkaldy-Willis criteria revealed excellent in 13 cases (40.6%), good in 16 cases (50%), fair in 2 cases (6.3%) and poor in 1 case (3.1%). Radiologically we analysed the adjacent segments in 25 cases except the cases which did not have the correspondence between the clinical findings and the radiological findings, and the fixated segments in 32 cases. The acceleration of degenerative changes were found in the above adjacent segments in 11 cases (44%) and in the below adjacent segments in 5 cases (27.7%). Also, those changes were found in the fixated segments with discectomy in 19 cases (50%) and in the fixated segments without discectomy in 9 cases (37.5%). In conclusion, we think that the Graf system in a lumbar region may biomechanically influence the adjacent segments. The mechanical effects of the device could be changed by the polyester bands which were followed for a longer period of time in the fixated segments. Therefore, randomized prospective studies comparing the Graf system to other treatement methods could provide clear indications for lumbar spinal disorders.

The 8 kDa antigenic protein of Clonorchis sinensis was partially purified by ammonium sulfate precipitation and subsequently by a column chromatographic steps. The purified protein was separated into 7 and 8 kDa protein bands through SDS-tricine gel electrophoresis, while the protein was found to migrate to a 8 kDa band in 7.5-15% SDS-PAGE. The molecular weight of the antigen was estimated to be 110 kDa by Superose 6 HR 10/30 gel filtration. The purified antigen strongly reacted with the human sera of clonorchiasis. The hyperimmune sera of BALB/c mice immunized against the 8 kDa protein were reacted with both the crude extract and the excretory-secretory product of adult worms, but not with the metacercarial extract. Immunohistochemical staining demonstrated that the protein was distributed to the tegument and subtegumental cells and also to the seminal receptacle. The present findings suggest that the 8 kDa protein is a partition of the multicomplex protein originating from various organs of adult C. sinensis, and that it is composed of several 7 and 8 kDa proteins.

PURPOSE: This study describes the CT and MR findings of mucoceles occurred in the post-operative maxillary sinuses. MATERIALS AND METHODS: CT and/or MR of 19 maxillary mucoceles in 16 patients who had been operated by CaldwelI-Luc procedure were reviewed. CT scans were performed after contrast enhancement in axial and coronal planes with 5mm thickness. Three cases were studied with a 2.0 T or 0.5 T MRI, which demonstrated multi-compartment lesions. RESULTS: The lesions were bilateral in 3 cases. Compartmentalization of the antral cavity was seen in 7 out of 19 involved sinuses. Surgical bone defect of the anterior wall was the most frequent route of extension (11 cases) and extension into the infratemporal fossa with erosion of posterolateral wall was seen in 7 lesions. In 6 cases, the lesions involved orbit. The expansile and erosive bone changes were localized in every case. In one case with multi-compartment lesion, both T1- and T2-weighted MR images showed different signal intensities in each compartment which represented different protein concentration. CONCLUSION: Post-operative maxillary mucocele showed CT findings of localized erosion and bulging most frequently at the anterior wall in which the bone windows were made during the previous surgery. Post-operative compartmentalization of maxillary antrum may cause eccentric expansion of mucocete and each compartment may show different signal intensities on MR.

Cutaneous focal mucinosis is a rare disease which usually manifests itself as a single asymptomatic papule or nodule, but vesicular presentati:on has only rarely been reported. This condition is one of many mucinoses, including localized lichen myxedematosus, acral persistent papular mucinosis, alopecia mucinosa, follieular mucinosis, and myxoid cysts which present with localized cutaneous lesions. We report a rare vesicular form of cutaneous focal mucinosis in a 42-year-old caucasian male who showed a slowly growing, 0.5 cm-sized, asymptomatic vesicle of one-week duration on his right knee. A histopathological examination revealed a localized accumulation of amorphous basophilic material which was positive on colloidal iron staining at pH 2.5. However, it was negative at pH 0.4 in an alcian blue stain, and negative on colloidal iron staining after treatment with hyaluronidase. The amorphous material was judged to be hyaluronic acid from the results of the above special stains. Proliferation of fibroblasts was also observed. Electron microscopy showed well-develuped endoplasmic reticulum and secretory vesicles in the fibroblasts. The lesion could not be completely removed even after two succesive wide excisions.

Syphilis is a communicahble disease caused by the motile microaerophilic spirochete Treponema pallidum, which is only a netural pathogen for human. Prevalence of syphilis and other sexually transmitted diseases has traditioially fluctuated with changes in sccia, conditions and sexual behavior. Although sexual contact is the main route of transmission, T. pallidum may also be infected through direct contact with syphilitic lesions, blood transfusion, ingestion of menstrual blood or vaginal secretions, or trsnsplacental transemission. Fomites as the means of transfer is only hypothetical and account for very few, if any, infection. Prosectors, blood handlers and laboratory technicians are at risk for accidental inoculation with infected materials. In extremely unusual circumstances, infection by means of contact with a skin lesion and human bite have been reported. We report two cases of eyphilis following the abnormal imposition of hands, which caused unnecessary erosive trauma with fingernails,

BACKGROUND: Unplanned extubation (UE) of patients requiring mechanical ventilation in an intensive care unit (ICU) is associated with poor outcomes for patients and organizations. This study was conducted to assess the clinical features of patients who experienced UE and to determine the risk factors affecting reintubation after UE in an ICU. METHODS: Among all adult patients admitted to the ICU in our institution who required mechanical ventilation between January 2011 and December 2013, those in whom UE was noted were included in the study. Data were categorized according to noninvasive or invasive management after UE. RESULTS: The rate of UE was 0.78% (the number of UEs per 100 days of mechanical ventilation). The incidence of self-extubation was 97.2%, while extubation was accidental in the remaining patients. Two cases of cardiac arrest combined with respiratory arrest after UE were noted. Of the 214 incidents, 54.7% required invasive management after UE. Long duration of mechanical ventilation (odds ratio [OR] 1.52; 95% confidence interval [CI] 1.32-1.75; p = 0.000) and high ICU mortality (OR 4.39; 95% CI 1.33-14.50; p = 0.015) showed the most significant association with invasive management after UE. In multivariate analysis, younger age (OR 0.96; 95% CI 0.93-0.99; p = 0.005), medical patients (OR 4.36; 95% CI 1.95-9.75; p = 0.000), use of sedative medication (OR 4.95; 95% CI 1.97-12.41; p = 0.001), large amount of secretion (OR 2.66; 95% CI 1.01-7.02; p = 0.049), and low PaO2/FiO2 ratio (OR 0.99; 95% CI 0.98-0.99; p = 0.000) were independent risk factors of invasive management after UE. CONCLUSIONS: To prevent unfavorable clinical outcomes, close attention and proper ventilatory support are required for patients with risk factors who require invasive management after UE.
