Of 782 premature babies who had been examed, 105(13.4%) were found to have retinopathy of prematurity(ROP). Between normal group and ROP group, there was statistically significant difference in birth weight, gestational age, duration of oxygen therapy and maximum arterial oxygen concentration. Between the group of regression(stage 1.2 to normal) and the group of progression(stage 1.2 to prethreshold disease) there was statistically significant difference in birth weight, gestational age and the circumferential extent of avascular zone. The 35% of prethreshold ROP eyes progressed to threshold ROP and mean interval from prethreshold to threshold ROP was 3.6 weeks.

The inferior alveolar nerve block is the most common method of local anesthesia for intraoral surgery at the posterior mandibular region. However, unexpected complications may occur when administering the local anesthesia. One of these uncommon complications is the fracture of the needle. If the injection needle is broken during the surgery, it should be removed immediately. However, this is one of the most difficult procedures. In this report, we present two cases of needle fracture during the procedure, and its successful removal under general/local anesthesia administration.

We compared the efficacy and toxicity of mitomycin C and Bacillus Calmette-Guerin (BCG) intravesical instillation in 86 patients with stage T1 of the superficial bladder tumor. Of them, 34 patients were received mitomycin C (40 mg/40 ml sodium chloride, once a week for 8 weeks) and 26 patients were received BCG (120 mg/50 ml sodium chlorids, once a week for 6 weeks) after transurethrat resection of bladder tumor and 24 patients (control) underwent transurethral resection alone. The mean follow up period was 24.8 months in control group, 26.8 months in mitomycin C group and 25.7 months in BCG group. The mean time to recur was 11.3 months in control group, 11.5 months in mitomcyin C group and 15.9 in BCG group but there was no significant difference among each groups (p>0.05). The overall recurrence rate was 34.6% in BCG group compared with 70.5% in mitomycin C group and 75.0% in control group, showing significant difference (p<0.05). Side effects were more common after BCG instillation than mitomycin C instillation. The most common side effect after BCG instillation was hematuria in 14 patients (53.8%). That of mitomycin C was cystitis in 10 patients (29.4%). Our study suggests that the prophylactic efficacy of BCG was significantly superior to that of mitomycin C, but there was no significant superiority regarding prophylactic effect of reduced mean time to recur in stage T1 bladder cancer patients. Additionally, further follow up studies were needed in mitomycln C.

All registered inactive leprosy patients were treated with multidrug regimen since 1985. We experienced two couples of relapsed leprosy patients among them. Three were relapsed as multibacillary type and one paucibacillary type. They were given the regimen regularly but taken irregularly. The spouse cases were relapsed 6months and 4years after index cases relapsed. Three patients were elevated PGL1 ELISA titer after relapse

PURPOSE: Ciliary abnormalities of the respiratory system usually accompany recurrent or persistent respiratory diseases such as paranasal sinusitis, bronchiectasis, rhinitis, and/or otitis media, since they cause certain derangements in ciliary cleaning activities. This disease is usually inherited by autosomal recessive trait, but may also be found to be acquired or transient in rare cases after heavy exposure to pollutants, cigarette smoking or severe infection. We performed this study in children with frequently recurrent or persistent respiratory diseases to clarify if the ciliary abnormalities are preceding factors. METHODS: We enrolled 17 children with suspected respiratory ciliary abnormalities. The indications for evaluation of ciliary ultrastructure were recurrent or persistent respiratory infections. Children with immunologic abnormalities were excluded. From August 2000 to July 2003, we performed a biopsy on nasal mucosa and examined the structure of ciliary status by using an electron microscope. RESULTS: Of the subjects, there were seven males and 10 females, aged 2 to 10 years. Out of the 17 subjects, 12 cases of chronic paranasal sinusitis, nine chronic coughs, nine frequent upper respiratory infections, seven cases of recurrent otitis media, four cases of recurrent pneumonia, and four cases of bronchial asthma were found. Out of the 17 cases on which histologic examinations were conducted, four cases showed pathologic findings, including one case of inner dynein arm defect, one of microtubular transposition, one of supernumerous tubules, and one singlet, respectively. CONCLUSION: It is essential for differential diagnosis and effective treatment to identify the abnormalities of ultrastructure of nasal cilia in children with symptoms of frequently recurrent or persistent respiratory diseases, if immunodeficiency or respiratory allergy could be excluded.

OBJECTIVES: Most children and adolescents have low levels of cancer knowledge and awareness, and infrequently engage in preventive behaviors. This study examined the effects of a short classroom-based intervention for cancer prevention on knowledge, attitude toward cancer preventability, self-efficacy, and behavioral intentions of fifth-grade elementary school students. METHODS: The study was based on a pre-post-follow-up, 2-group, quasi-experimental design. Participants in the intervention group attended two 40-minute sessions on cancer prevention education and watched a music video about cancer prevention, while participants in the control group were only exposed to the music video. Self-reported knowledge, attitude toward cancer preventability, self-efficacy, and behavioral intentions were assessed 1 week pre-intervention and post-intervention, as well as 3 months post-intervention. RESULTS: The 3-month post-intervention results revealed partial effects, indicating that the education intervention improved knowledge and attitudes toward cancer preventability; however, no effects were observed on self-efficacy and behavioral intentions 3 months after the intervention. CONCLUSIONS Long-term regular booster sessions are required to improve not only social-cognitive factors, but also behavioral intentions, which could result in behavior changes promoting cancer prevention.
