Botulinum toxin, a neurotoxin derived from Clostridia Botulinum, has been injected into the target muscle(s) for the treatment of several kinds of voice and speech disorders at the Voice Clinic, Yonsei Institute of Logopedics and Phoniatrics since December 1995. Criteria for the diagnosis and method of injection for spasmodic dysphonia, mutational dysphonia, muscle tension dysphonia, dysphonia after total laryngectomy, and stuttering were summarized. Among 144 patients with adductor type spasmodic dysphonia, who were injected one time to maximum 8 times during the 27 months, 90% were recognized as having better than slight improvement. Even though the injected cases were small, not only the abductor type spasmodic dysphonia, but also the intractable mutational dysphonia or muscle tension dysphonia resistant to voice therapy revealed that botulinum toxin injection would be another options for treatment. Patients who cannot phonate after total laryngectomy and some forms of adulthood stutterers can also be candidates for the injection of botulinum toxin.

Tuberculosis is a disease with high morbidity and mortality in children worldwide. Despite significant improvements in diagnostic methods, scientific researches and clinical trials for new regimens of treatment or prevention in adult tuberculosis, childhood tuberculosis has been relatively neglected. Children are at high risk of severe disease, and reactivation of latent infection in adulthood perpetuates the epidemic. Therefore, a policy of tuberculosis control in childhood should be emphasized to improve control in the total population. To understand the new view of childhood tuberculosis, this article describes changes in the disease's national epidemiology, new diagnostic tools and treatment strategies, and multi-drug resistance.

The normal aging process on speech production and these changes are perceived by listeners. This study examined whether age perception changed under various conditions of prosodic manipulations in normal listeners, comparing the prosodic changes according to age and sex in adulthood. The older and younger voices were resynthesized by manipulation of the speaking rate and pitch to shift the perceived age of the groups toward each other. Two-way repeated ANOVA were conducted to determine if the prosodic type of resynthesized cue resulted in a significant shift in perceived age of young and old voices. The manipulation of the speaking rate resulted in a significant shift in perceived age for the older and younger groups. A significant shift in age estimates was not observed for the younger male group when pitch was manipulated. There were significant gender-by-age group interactions for prosodic manipulation type. Age-related changes in the prosodic properties of speech may ultimately influence speech perception.

Ecological aspects of Cryptocercus kyebangensis life history were investigated via laboratory rearing and field observations. The number of antennal segments and head width were used to classify the first four instars. The results, which combine both the field collection and the laboratory rearing, indicate that eleven instars occur in C. kyebangensis. It supports the proposal on the number of instars of Park and Choe (2003c) based on field collections. A total of 388 nymps from 13 colonies were collected prior to winter to investigate overwintering stages. Of them,4％ (n = 17) were the second instars, 57％ (n = 220) were the third instars, and 39％ (n = 151) were the fourth instars, respectively. Thus, most of them overwinter in the third or fourth instars. The results indicate that young nymphs of C. kyebangensis have to reach at least 3rd or 4th instar to survive low temperature environment of winter. According to seasonal dynamics of populations, C. kyebangensis reaches adulthood in the summer of the fourth or fifth year (4-5 yr span) after their birth.

Morphological characteristics of nymphal instars are described for a Korean wood-feeding cockroach, Cryptocercus kyebangensis. Eleven instars, including adults, were tentatively identified. Female adults had apicolateral emargination and a truncated apical median prominence in the seventh sternite, and female nymphs of the other instars except for the last had a narrowly rounded apical median prominence in the seventh sternite. In the last instar, the seventh sternite was partially desclerotized and somewhat shriveled at the start of the emarginated area. In contrast, males showed no emargination in adults, and had a rounded broad apical median in this area of all instars. In the ninth sternite, female nymphs had a medium notch on the caudal margin and styli were separated before reaching adulthood, whereas no such notch was observed in male nymphs. The styli remained prominent in the ninth sternite of male adults.

Noma is a gangrenous disease of the orofacial region that leads to severe facial tissue destruction and is a significant cause of death among children. With the advent of modern antibiotics and improved nutrition, children with noma may survive into adulthood, but must face the challenge of undergoing repair of the sequelae of noma. This report describes a case of bony fusion of the maxilla and mandible in a 28-year-old female patient, which was a sequelae of a childhood case of noma.

Twenty-one adoptive parents participated in this study on adoption-related conflicts perceived by adoptive parents in open adoption. Q-methodology, which provides understanding of individual attitudes and experiences, identified three types of conflict. Type 1 experienced a great deal of conflict and concern prior to the adoption decision; they also faced difficulties stemming from lack of information about parenting an adopted child and institutional inertia. For type 2, the major factors of conflict were discord among siblings, negative bias against adoption in the community, and insufficient national assistance. Type 3 reported that they feel concerned for their adopted-child's developmental and psychological wellbeing they worried that adoption status might lead to behavioral and attitudinal problems in their adopted-child during youth and young adulthood.

The purpose of this study is to identify the acoustic changes according to age and to provide the evaluation criteria of elderly voice. The number of 120 Korean adults (three age groups * two sex groups) proceeded sustained three vowels, read apart of 'Taking a walk' and explained a picture. The data was analyzed acoustically with MDVP of CSL. The results showed that: 1)there was statistically most significant changes in sex and age in F0 than the others but no significant in Shimmer. 2)acoustic parameters were changed from young adulthood to old age. Different patterns of change with aging were observed in men and women.

Angiokeratomas represent vascular lesions and are histologically characterized by superficial dermal vascular ectasia with overlying epidermal hyperkeratosis. Angiokeratoma circumscriptum is one of five types in the group of the angiokeratomas. The lesion is present from birth but may appear in childhood or adulthood. Angiokeratoma circumscriptum is typically hyperkeratotic papules or nodules situated unilaterally on the foot or distal aspect of the leg, but can occur elsewhere on the body. Isolated tongue involvement is very rare. We report a 12-year-old boy with angiokeratoma circumscriptum of the posterior dorsal tongue with a review of the literatures.

Objectives: The purpose of this study is to analyze the relationship between dual smoking and mental health. Methods: This study was conducted on 5,879 Korean adults, and a logistic regression analysis was conducted to investigate the relationship between smoking type and mental health. Results: The types of smoking were surveyed as 'dual smoking' 6.1%, 'electronic cigarette' 1.7%, 'general smoking' 12.1%, and 'non-smoking' 80.1%.. The risk of diagnosing depression in the dual smoking group was 2.87 times higher than in the non-smoking group, the risk of depression was 1.66 times higher than in the non-smoking group, and the risk of stress was 1.62 times higher. Conclusion: Even in adulthood, health education such as smoking prevention education and smoking cessation education should be conducted.
