BACKGROUND: The length of postoperative drug therapy remains controversial in pulmonary tuberculosis. We analyzed our experiences to determine the postoperative duration of chemotherapy after resection. METHODS: A retrospective review was performed in 66 of 95 patients that underwent pulmonary resection for pulmonary tuberculosis between January 1993 and December 1998. We compared the relapse rates according to the length of postoperative chemotherapy in each group, classified by the results of sputum AFB culture before the surgery, the number of resistant durgs, the number of prior treatment and the division of anti-TB drugs used postoperatively. RESULTS: Fifty three of 66(80.3%) were men and 13(19.7%) were women with a median age of 33.5 years(range, 16 to 63). The mean lengths of the pre-and post-operative chemotherapies were 4.9 months, and 12.9 months respectively. Five of 66 patients(7.6%) relapsed during the mean period of follow up(39.7 months). In the group less than three times of the prior treatment, there were two relapses(20%) in Ed-the highlight above-rephrase 10 patients that were medicated for 6 months or less, and one relapse in 43 patients(2.3%) that took medicine for more than 6 months(p=0.03). In the group using second-line drugs postoperatively, there was one relapse(25%) in four patients that were medicated for 12 months or less. No patient in a total of 17 that received medicine for more than 12 months relapsed(p=0.03). CONCLUSION: We recommend that patients with the prior treatment less than three times should be treated for more than 6 months after resection and patients using the second-line drugs postoperatively should be medicated for more than 12 months.

Objective To compare the clinical effect of different materials dentures in repaired of teeth. Methods A retrospective analysis of 570 patients with framework removable partial dentures , which were divided into the Vitallium 2000 group, the pure titanium group and the Co-Cr alloy group randomly from Jan. 2010 to Dec. 2012 in our hospital. Compare the clinical effect of three groups. Results The emplacement rate (χ2=10.283,P<0.05)and the 2-week adjust rate (χ2=16.262,P<0.05)of three groups were statistical different significantly. The incidence rate of denture stomatitis(χ2=12.773,P<0.05),the masticatory efficiency(t=8.194,P<0.05)and the incidence rate of adverse reactions (χ2= 6.028,P < 0.05)of three groups were statistical different significantly. The patients′satisfaction (χ2=2.191,P>0.05)of three groups weren′t statistical different significantly. The degree of comfort(χ2= 6.827,P < 0.05),the speech satisfaction(χ2= 6.002,P < 0.05) and the chewing speech satisfaction (χ2=5.838,P<0.05)three groups were statistical different significantly. Conclusion The clinical effect of the Vitallium 2000 group is better of weight , strength and stability than other groups. The Vitallium 2000 frame removable partial denture is nontoxic , fastness and no peculiar smell , which could be ensure the aesthetics , the degree of comfort and improve the masticatory efficiency , worthy to recommend its clinical use.

OBJECTIVETo investigate the synergistic effect of transforming growth factor-beta1 (TGF-beta1) and platelet-derived growth factor-BB (PDGF-BB) on the expression of integrin beta3, in periodontal membrane of rat orthodontic tooth.

METHODSAn orthodontic tooth movement model was established. Up to 32 experimental rats were randomly divided into four groups according to a random number table. The four groups were injected with 1% PBS, TGF-beta1 (5 ng), PDGF-BB (10 ng), and combined TGF-beta1 (5 ng) and PDGF-BB (10 ng) in the buccal submucosal, respectively. The volume injected in each group was 0.1 mL. The animals were then sacrificed on the 10th day. The left maxillary first molar and periodontal tissue were taken. Different expressions of integrin beta3 were detected in periodontal tissues through immunohistochemistry. Mean optical density (OD) values of the positive fields were examined. The data obtained were analyzed through ANOVA. The data followed normal distribution, and were compared via t-test.

RESULTSCompared with the control groups, the expression of integrin beta3 was higher in the experimental groupin tension sides (P < 0.01). Significant differences in tension sides between the single-injection groups and the combined group were observed (P < 0.01). Compared with the control groups, the expression of integrin beta3 was higher in the experimental group in compression sides (P < 0.05). In addition, there was no significant differences in compression sides between the single-injection groups and the combined group (P > 0.05).

CONCLUSIONIn terms of local regulatory factors, TGF-beta1 combined with PDGF-BB enhance the expression of integrin beta3 in the periodontal membrane and accelerate periodontal remodeling. The synergistic effect of the two growth factors is better than the single growth factor.

One hundred eighty infants with oxygen therapy who were under 2,500gm birth weight or under 37 weeks of gestational age, were examined between January 1990 and November 1992. We performed clnical analysis and results were as follows. 1) Fifty six infants (31.1%) were diagnosed as retinopathy of prematurity. 2) The first examination was performed at 2.5 weeks of life on average, and the retinopathy of prematurity was diagnosed at 3.8 weeks on average. 3) The incidence of retinopathy of prematurity was highly associated with low birth weight (< or =1,890 gm), low gestational age ( < or =33.1 weeks), and high oxygen concentration with long duration (FiO2> or =0.4 over 1 week)(P<0.005). 4) Other associated risk factors were idiopathic respiratory distress syndrome, anemia, neonatal hypoxia and sepsis.

In order to investigate the occurrence characteristics of cancer in terms of industry in Kwangju-Chonnam area, medical utilization records of industrial medical insurance corporations during the period of 1987 to 1988 were reviewed for the identification of neoplastic disease. The cases obtained from the medical records were followed up for the verification and to get additional information. Standardized incidence data were compared by occupational characteristics. Multiple logistic regression analysis was applied to analyze the difference of incidence or distribution of cancer as a whole or of some selected cancer. Total cases of cancer identified were 242 during the study period. Annual incidence rate was calculated as 123.1 per 100,000 person. The frequent types of cancer were cancers of stomach, liver, lung, colon and rectum, bladder and lymphoma in descending order. Employees of mine and other sand handling industries showed significantly higher risks for cancer of stomach and cancer as a whole. Employees of the transportation industry showed the higher risk for cancer of liver. Workers in small-sized industry (< or = 100) had a higher risk for cancer than who in large-sized industry (>100). These findings suggested the effect of occupational environmental exposure to cancer development.

Acrodermatitis enteropathica(AE) which starts in early infancy after weaning is a rare hereditary chronic disorder of zinc absorption. AE is characterized by alopecia, diarrhea and skin lesions localized to periorificial areas and acrally on the extremities. However, recent reports presented Transient Symptomatic Zinc Deficiency(TSZD) in preterm infants. TSZD is clinically similar to AE and skin lesions rapidly heals after zinc supplementation. When the treatment was withheld, no recurrence was seen. We experienced a TSZD case in a cow's milk fed, preterm infant, so We report it with a brief review of literature.

Neurocutaneous melanosis (NCM) is a rare congenital syndrome consisting of benign or malignant melanotic tumors of the central nervous system with large or numerous cutaneous melanocytic nevi. The Dandy-Walker complex (DWC) is characterized by an enlarged posterior fossa with high insertion of the tentorium, hypoplasia or aplasia of the cerebellar vermis, and cystic dilatation of the fourth ventricle. These each two conditions are rare, but NCM associated with DWC is even more rare. Most patients of NCM with DWC present neurological symptoms early in life such as intracranial hemorrhage, hydrocephalus, and malignant transformation of the melanocytes. We report a 14-year-old male patient who was finally diagnosed as NCM in association with DWC with extensive intracerebral and spinal cord involvement.
