BACKGROUND: Otitis media with effusion(OME) is a very common disease in pediatric age. However, a few literatures on epidemiologic study of otitis media with effusion are available in Korea due to the great variability of its diagnostic criteria and clinical features. The aim of this study is to provide the estimate of silent otitis media prevalence for preschool age. METHODS: The study population includes 329 children enrolled in 6 kindergartens in Kunsan city from April 1 to 10, 1995. Silent otitis media was diagnosed with otoscopy, pneumatic otoscopy and impedance audiometry by DANAC 40 model impedance audiometer from DANA JAPAN Co. RESULTS: The prevalence of silent otitis media with effusion was 14.5% and peak at 6 years of age(17.8%).The prevalence of silent otitis media with effusion according to sex were 11.8% in boys group, 17.9% in girls group. Nine cases(11.8%) involved bilaterally. Forty three cases(89.6 %) were asymptomatic cases. CONCLUSIONS: Among 329 preschool children, the prevalence of silent otitis media with effusion was 14.5%. The prevalence by sex showed slightly higher in girls group than boys group. OME involved unilateral site mostly and subjective symptoms were rare.

Reexpansion Pulmonary edema is the iatrogenic complication which develops in a lung that has been rapidly reinflated after varied period of collapse secondary to a pneumothorax or a pleural effusion of large volume. Its incidence is relatively low, but can sometimes lead to death. The prevention of this disease is known well, but the definite treatment method has not been known in severe case although there have been conventional ventilator therapy and some medications in mild case. Asynchronous differential lung ventilation is a new therapeutic modelity which is applied independently to bilateral lungs in respiratory failure patients secondary to ventilation-perfusion mismatch, preoperatively, intraoperatively or postoperatively. By asynchronous differential lung ventilation, we successfully treated a severe reexpansion pulmonary edema in 29 year old male patient. Therefore we suggest that asynchronous differential lung ventilation is the treatment of choice for severe reexpansion pulmonary edema.

We report herein an unusual case of tick bite. A 56 year old woman complained of erythematous nodular skin lesion on the left upper chest. An excision biopsy specimen of the lesion showed darkish-red nodule, in which there was a tick. It was identified as an adult female of Ixodes nipponensis by the scanning electron microscopic examination.

Purpose: This study assessed the results of surgical treatment for Neer type-II and type-V unstable distal clavicle fractures via hybrid fixation with a locking compression plate and finger trap wire. Materials and Methods: From September 2016 to April 2018, 15 patients treated for Neer type-II and type-V unstable distal clavicle fractures using hybrid fixation were analyzed retrospectively. The clinical results were analyzed based on the radiological healing time, range of motion of the shoulder joint, American Shoulder and Elbow Society (ASES) score, and the University of California at Los Angeles (UCLA) shoulder score. Results: The range of motion of the shoulder joint completely recovered to the normal range within 9.2 weeks on average (6−24 weeks). Furthermore, the follow-up of the clinical trial showed excellent results, including an ASES score of 98.5±2.3 and an UCLA score of 34.2±1.3. In addition, fracture union was successfully achieved in all cases, and was identified during week 15 on average. Conclusion For the treatment of unstable distal clavicle fractures, hybrid fixation is a useful surgical method with excellent clinical outcomes through rapid recovery of the range of motion of the shoulder joint after surgery.

BACKGROUND: Hypothermia following the induction of anesthesia is caused by core to peripheral redistribution of body heat. It has been reported that propofol causes more severe hypothermia than sevoflurane by inhibiting thermoregulatory vasoconstriction during surgical procedures. Therefore, we evaluated the induction and maintenance of anesthesia with intravenous propofol to determine if it causes more core hypothermia than inhaled sevoflurane. METHODS: Forty-five patients who underwent hysterectomy were divided into two groups randomly, a propofol-remifentanil (PR) anesthesia group and a sevoflurane-remifentanil (SR) anesthesia group. Each group was subjected to anesthetic induction with either 1.5 mg/kg propofol or inhalation of 5% sevoflurane, respectively. Anesthesia in the former group was maintained with propofol while it was maintained with sevoflurane in the latter group. Specifically, 6-10 mg/kg/hr propofol, 3 L/min medical air, 2 L/min O2, and 0.25 mg/kg/hr remifentanil were used in the PR group for maintenance, while 1.5 vol% sevoflurane, 3 L/min medical air, 2 L/min O2 and 0.25 mg/kg/hr remifentanil were used for maintenance in the SR group. We measured the core temperature 8 times, prior to induction and 10, 20, 30, 45, 60, 75 and 90 minutes after induction. RESULTS: Core temperatures decreased in both the PR and SR group during surgical operation, but there was no significant difference between the two groups. CONCLUSIONS: Anesthesia induced and maintained by propofol did not cause a greater degree of hypothermia than sevoflurane.

PURPOSE: To evaluate the classification of punctal stenosis based on the shape of the external punctum, clinical characteristics and histopathologic features. METHODS: Patients who experienced tearing and were diagnosed with punctal stenosis were evaluated in this study. Punctal stenosis was classified according to the shape of the lower external punctum, which included membranous type, slit type, horseshoe type, and pinpoint type. Tear meniscus height, 2% fluorescein dye disappearance test and lacrimal pathway irrigation were measured or performed. For treatment, a punctal snip operation and silicone tube placement were performed, and the peripunctal histopathological findings were evaluated. RESULTS: Punctal stenosis was classified into four types: membranous type (17 eyes, 21.5%), slit type (11 eyes, 13.9%), horseshoe type (25 eyes, 31.6%), and pinpoint type (26 eyes, 32.9%). The tear meniscus was significantly higher, and the 2% fluorescein dye disappeared significantly more slowly in the punctal stenosis group. However, correlation of the tear meniscus height and 2% fluorescein dye disappearance test with the punctum shape was not statistically significant. A history of previous chemotherapy was significantly associated with the occurrence of punctal stenosis, especially the membranous type (p < 0.05). Histopathologic evaluation of the punctum showed differences between the punctum types. Pinpoint puncta exhibited a high density of muscle fibers, while they were faintly visible in the membranous type. CONCLUSIONS: Acquired punctal stenosis has various shapes, and the major types of stenotic puncta exhibited unique histopathologic features. Punctal stenosis and its pathophysiology may be related to multiple factors, such as age and systemic 5-fluorouracil chemotherapy history.
