Efficacy and Safety of Suction-assisted Cartilage Shaver with Fibrin Glue in Treating Axillary Osmidrosis / 대한피부과학회지

BACKGROUND: Axillary osmidrosis causes significant emotional distress and embarrassment. Although numerous surgical procedures have been developed for the treatment of axillary osmidrosis, there is no decisively effective one. OBJECTIVE: This paper is to assess the efficacy and safety of suction-assisted cartilage shaver with the use of fibrin glue to treat axillary osmidrosis. METHODS: 18 axillary osmidrosis patients were treated with suction-assisted cartilage shaver followed by injection of fibrin glue. The effectiveness of the treatment used in this study was evaluated by measurement of axillary malodor both pre- and postoperatively. Patient satisfaction was surveyed as well. RESULTS: The postoperative test demonstrated that there was remarkable decrease in axillary malodor. Of the 18 patients, 17 patients (94.4%) expressed positive satisfaction. Complications including postinflammatory hyper-pigmentation (27.8%), hematoma and skin necrosis (5.6%), scar (5.6%), infection (5.6%) and hidradenitis suppurativa (2.8%) were reported. CONCLUSION: The use of suction-assisted cartilage shaver with fibrin glue proved itself an effective and safe treatment for axillary ormidrosis.

Keloids Treated with a Suction-Assisted Cartilage Shaver: A Report of Four Cases / 대한피부과학회지

Surgical excision of keloids is generally not accepted as a first treatment option, but many reports have described specialized surgical methods, such as intralesional and intramarginal excision. This operation preserves the active peripheral portion of the keloid and excises the central bulky lesion. The suprakeloidal flap technique and keloid core excision involve intralesional excision. These methods are known to be associated with a low probability of recurrence or lesion exacerbation because the remaining keloidal lesion acts as a barrier. However, several complications, such as partial necrosis and flap congestion, have been reported, especially in large lesions. We describe cases of four patients with keloids on the chest or abdomen. All patients complained of pain or itching due to the keloids. Patient age ranged from 20 years to 54 years, and the number of lesions ranged from one to seven. The largest lesion measured 10x8 cm. We treated the lesions by the dermal shaving method using a suction-assisted cartilage shaver, and the lesions were markedly flattened in all cases. Because this surgery is performed through an incision for a cannula, it allows more rapid healing and causes less postoperative pain with fewer severe complications. It also has the advantage of requiring less effort and time due to the use of motorized curettage with suction. The suction-assisted cartilage shaver using dermal shaving method seems to be an effective alternative treatment modality for reducing the lesional size of keloids.

The Environmental and Educational Management Effects of Atopic Dermatitis in a Seoul Elementary School / 소아알레르기및호흡기학회지

PURPOSE: This study was conducted to address a school-based program to properly manage atopic dermatitis in school children. METHODS: A modified Korean version of written questionnaires from the International Study of Asthma and Allergies in Childhood was completed by the parents of 125 first-grade children. Skin prick tests (SPTs) for nine common inhalants and food allergens were performed. Air cleaners, HEPA vacuum cleaners, wet blackboards, and wet towels were used to clean the floor in the classroom. Students and their parents participated in school-based educational programs about atopic dermatitis. A follow-up questionnaire and SPTs were performed at 6 months after improving the classroom conditions. Indoor air quality was measured at the 3 months interval in July and September of the same year after the school-based program. RESULTS: The prevalence of "itchy eczema ever" and a "diagnosis of atopic dermatitis, within the last 12 months" was 26.4% and 12.0%, respectively. Eleven students (34.4%) showed positive results among 32 students who were examined with SPTs. All children who showed positive results were sensitized with house dust mites. After the environmental change, the prevalence of "itchy eczema within the last 6 months" and "diagnosis of atopic dermatitis within the last 6 months" was 14.7% and 7.8%, respectively. Skin reactivity assessed by mean wheal diameter decreased. Measured indoor air quality values improved in all classrooms by September. CONCLUSION: School-based environmental changes and educational programs including a partnership among home, school, society, and the public health care center could be applied to better manage atopic dermatitis in school children.

High Flow Nasal Cannula versus Nasal CPAP in Preterm Infants

PURPOSE: The aim of the study was to investigate the change in usage and clinical outcomes of using a humidified high flow nasal cannula (HHFNC) in preterm infants. METHODS: A retrospective review of patients with gestational age <32 weeks born at our neonatal intensive care unit from January 2008 to March 2011 was performed. First, data were compared between Era 1 (January 2008 to February 2009) and Era 2 (March 2009 to March 2011) to describe the increased usage of HHFNC. Second, the patients (gestational age 25-30 weeks) were divided into two groups to compare clinical outcomes. nasal continuous positive airway pressure (NCPAP) and HHFNC groups who received either NCPAP or HHFNC as a respiratory support within 14 days of birth. RESULTS: Compared to Era 1, HHFNC usage increased from 10 to 55% in Era 2, whereas NCPAP usage decreased from 40 to 5%. No difference in pulmonary or adverse outcomes including the incidence of reintubation and bronchopulmonary dysplasia (BPD), days on oxygen and a ventilator, and other outcomes was observed between the HHFNC and NCPAP groups. Days to reach full feed (32.2+/-16.7 vs. 24.7+/-10.2, P=0.05) and regain birth weight (20.9+/-16.9 vs. 17.2+/-4.3, P=0.04) decreased in the HHFNC group. CONCLUSION: HHFNC was feasible and did not differ in respiratory and other outcomes, but days to reach full feed and regain birth weight decreased in the HHFNC, when compared with the NCPAP. An additional prospective multicenter designed study is needed to better define safety and efficacy of HHFNC.

Effect of NFI-C on the Expression of Smad and TGF-betaR1 / 대한해부학회지

NFI-C null mice demonstrate aberrant odontoblast differentiation and abnormal dentin formation, and thus develop molars lacking roots. However, other tissues and organs in the body including ameloblasts appear to be unaffected. Abnormal dentin in NFI-C null mice shares morphological similarities to the osteodentin that is formed in dental caries. However, little is known about the relationship between NFI-C and osteodentin formation. In this study, to elucidate the molecular characteristics of abnormal odontoblast in NFI-C null mice, we examined the levels of Ask-1, Cdc-2, Smad2/3, and TGF-betaR1 in cell culture and tissue sections from NFI-C null mice using immunofluorescence and immunohistochemistry. NFI-C protein was localized in the nucleus and cytoplasm of normal odontoblasts in vitro. Ask-1 and Cdc-2 proteins were shown in the perinuclear cytoplasm of both normal and NFI-C null mice. There were no differences in the pattern of production of Ask-1 and Cdc-2 proteins between normal and NFI-C null mice. Smad2/3 was not found in the odontoblast and subodontoblastic cells of the normal mice, whereas NFI-C null mice showed Smad2/3 immunoreactivity in the odontoblasts and subodontoblastic cells of the tooth pulp. TGF-betaR1 was weakly immunopositive in the odontoblast and subodontoblastic cells of normal mice, whereas it was detected strongly in the subodontoblastic cells of the NFI-C null mice. These results suggest that disruption of NFI-C increased the expression of Smad2/3 and TGF-betaR1 in developing odontoblasts and consequently caused abnormal dentin formation, similar to osteodentin.

Effects of Melatonin on MDPC-23 Cells Differentiation / 체질인류학회지

Melatonin is the major hormone released from the pineal gland and regulates a variety of physiological and pathophysiological processes. According to the recent studies the melatonin plays an important role in regulation of bone growth. The purpose of this study was to determine whether melatonin promotes the cell differentiation and nodules formation in MDPC-23 pre-odontoblast cell line. MDPC-23 cells were cultured for up to 15 days in growth media containing differentiation medium with melatonin or without melatonin. Cultures were stained with Alizarin-S. The expression of the mRNAs for DSPP, OC, ALP and NFI-C were analyzed by RT-PCR. The results were as follows. Cultures containing melatonin at day 15 showed extensive mineralization as compared with control cultures. Melatonin increased the expression of DSPP and OC mRNAs in MDPC-23 cells in a concentration-dependent manner. However, melatonin did not changed ALP expression. Melatonin markedly decreased mRNA expression of NFI-C in early stage cultures as compared with control cultures. These results demonstrated that melatonin is capable of promoting MDPC-23 cells differentiation and mineralization and suggested that melatonin may play an important role in dentin formation.

Development of the Home-Based Pulmonary Rehabilitation Program for Patients with Chronic Lung Disease / 결핵

BACKGROUND:Even though it is well known that pulmonary rehabilitation (PR) improves exercise capacity, and the quality of life, in patients with chronic lung disease, not many patients can attend hospital based intensive PR in Korea. The purpose of this study was to develop a method for a home-based PR program, and study its effectiveness. METHODS:Twenty patients with chronic lung diseases were randomly divided into two groups : a home PR group comprising of 10 male patients, with a mean age of 70 years, and a control group comprisiong of 10 male patients, with a mean age of 65 years. We developed exercise programs, depending on the exercise capacity of each patient, which were easy to do at home. The PR program consisted of a 12 week period of enforced aerobic (mostly walking) and muscle strengthening exercises, as prescribed by the exercise specialist, in accordance with the functional capacity of the patient. In addition to the education, nutritional and psychiatric consultation was undertaken, and respiratory muscle training arranged. Patients visited hospital every 2 weeks for evaluation and exercise prescription. RESULTS: All patients finished the 12 week course of therapy. Following the home PR, the endurance times and work capacity of the upper and lower extremities were significantly increased in the treatment group in comparison to the controls. The six minute working (Eds note : should) 'working' read 'walking'?) distance was increased from 465+/-60m to 508+/-37m and the maximal inspiratory pressure from 72.8+/-27.2cmH2O to 91.4+/-30.9 cmH2O. The quality of life, as assessed by St Georges Respiratory Questionnaire (SGRQ), was also improved following PR. (Eds note : do you have figures for before and after, and a reference for the SGRQ? i.e. for the main paper.) CONCLUSION: The home PR program we developed seemed to be applicable, and effective, to most of the patients with chronic lung diseases in the study.

A Case with Systemic Lupus Erythematosus Complicated with Multifocal Osteoarticular Tuberculosis / 대한류마티스학회지

Infection is a frequent problem in patients with systemic lupus erythematosus (SLE). Infections contribute greatly to the morbidity of patients and are one of the commonest causes of death. The high frequency and unusual spectrum of infections can be attributed to the multiple disturbances of immune function in SLE in combination with the effects of immunosuppressive therapy. There is increasing evidence to indicate that opportunistic infections including tuberculosis make a large contribution to the infectious mortality in SLE. Tuberculosis is a major cause of morbidity and mortality, particularly in our country where tuberculosis is still endemic. The indolent nature of tuberculous bone and joint disease often leads to delayed or missed diagnosis, sometimes with devastating consequences for the patient. We report a case of multifocal and complicated osteoarticular tuberculosis developing in the spines and knee joint due to delayed diagnosis, with review of literatures.
