We report a case of a 41-year-old female patient who suffered from the acute abdominal pain for several hours after eating raw sea-fishes. After the fibergastroscopy and the abdominal C-T scan, the clinicians found a gastric submucosal mass and performed the explolaparotomy to get an wedge of stomach. Sections revealed a larva surrounded by phlegmonous inflammation with intense eosinophilic infiltration in the widened gastic submucosa. The larva presented the characteristics of the Anisakis: two lateral chords with renette cell, thich smooth cuticle and well developed musculature.

Ninety-three dry mandibles in Korean adults were radiographed and fifty-two hemimandibles were sectioned in an attempt to analyze the intramandibular courses of the mandibular canal and the internal structure of the mandibles. On radiographs, the intramandibular course of the mandibular canals was most in which located in the middle portion of the mandible, the shape of the mandibular canals was almost round and the average diameter of the mandibular canals was 2.0 +/- 0.4mm, encapsulated by thin cortical plates of 0.5mm thickness on sectioned specimens. In regard of facio-lingual relation, the prevalence of pattern which the mandibular canal ran nearly to the lingual cortical plate, and turned abruptly towards the buccal side was 70% of observed specimens. According to superior-inferior relation, the prevalence in which mandibular canals ran inferiorly, anteriorly and then, had an angle superiorly in the second mandibular molar region was 39.0%. Taken all together, in most of the case, the anterior border of the mandibular canal is located around the premolar region, and the mental foramen is opened nearly the second premolar. Therefore, it may be suggested that osteotomy has to be taken at the anterior place next to the canine region, at the 2.4mm below to the mental foramen on genioplasty.

INTRODUCTION: There has been an increasing interest in the relationship between sleep and suicidality. In addition, suicidal patients habitually report their sleep problems. Although sleep-related complaints and electroencephalographic changes are generally encountered in psychiatric disorders, sleep complaints such as insomnia, hypersomnia and nightmares are more common in suicidal patients. In current study, we aimed at investigating the relationship between self-reported sleep duration and suicidality in general population. METHODS: One thousand general population (male : female=500 : 500, mean age=39.6+/-11.6 years, ranged age=20-77 years) completed Center for Epidemiologic Study-Depression (CES-D), Beck Suicide Intent scale (BSI), Spielberger State-Trait Anger Expression Inventory (STAXI), Barratt Impulsiveness Scale (BIS), Morningness-Eveningness Scale (MES) and brief questionnaire of sleep habits. RESULTS: After controlling for age and sex, score of BSI was correlated positively with the score of CES-D, STAXI and BIS on partial correlation analysis (r(p)=0.251 ; p<0.001, r(p)=0.352 ; p<0.001, and r(p)=0.175 ; p<0.001, respectively). In addition, score of BSI was inversely correlated with the score of MES (r(p)=-0.066; p=0.037). However, score of BSI showed no significant correlation with sleep duration. However, regression analysis revealed that short (<6 hrs) or long (>10 hrs) sleep duration, the family history of psychiatric illness, the score of CES-D, and the score of STAXI predicted higher score of BSI significantly in total subjects (F=17.837, adjusted R2 =0.166 ; p=0.003, p=0.003, p<0.001, and p=0.003, respectively). This model was explained better in depressed subjects with 16 or higher score of CES-D (F=9.920, adjusted R2=0.298). CONCLUSION: Current result suggested that not only short sleep duration (<6 hrs) but also long sleep duration (>10 hrs) might be related to suicidality.

OBJECTIVES: Working at other times than the regular day shift has been reported to be a stressor associated with health consequences and mental disorders as well as disturbance of sleep. In current study, we aimed at investigating the relationship between work schedule, sleep quality and depression among police officers. METHODS: Eleven hundreds and forty five police officers (male:1040, female:105) completed questionnaires of basic socio-demographic data, Pittsburgh Sleep Quality Index (PSQI), Korean Scale of Occupational Stress (KOSS), Impact of Event Scale - Revised (IES-R) and Center for Epidemiologic Study-Depression (CES-D). RESULTS: After controlling for age, sex and educational level, score of CES-D was correlated positively with the score of KOSS, PSQI and IES-R on partial correlation analysis (r=-0.077;p=0.009, r=0.262;p<0.000 and r=0.421, p<0.000, respectively). Logistic regression analysis revealed that female sex, age, the score of KOSS and IES-R and schedule of rotating shift work predicted higher score than 16 score of CES-D significantly in total subjects (p=0.023, p=0.015, p=0.000, p=0.000 and p=0.022, respectively). CONCLUSION: Current result suggested that not only female sex, age, higher occupational stress and impact of event scale but also rotating shift work schedule might be related to depression among police officers.

Retroperitoneal tumors are relatively rare, accounting for 0.2% of all cancers; many different histologic types are present, and primitive retroperitoneal germ cell tumors constitute a small miniority of about 3%. Most primary extragonadal germ cell tumors (EGCTs) arise from the mediastinum of retroperitoneum in young males. The authors experienced a case of primary extragonadal mixed germ cell tumor with a 43-year-old woman complaining left lower abdominal pain. With the case report, a brief review was made.

This study was performed to investigate the antibacterial, antioxidant, and termite repellent effects of citronella oil (CiO) and lemongrass oil (LO). When the antibacterial activity against Staphylococcus (S.) aureus with various levels of antibacterial resistance were tested, a 0.05% concentration of CiO and LO completely inhibited the growth of all tested S. aureus strains. Evaluation of the antioxidant effect demonstrated that the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity of CiO was 2~3 times greater than that of LO. Among trial products made with various combinations of CiO and LO, a CiO : LO ratio of 6 : 4 had the most potent termite repellent effects. Assessment of acute toxicity of the trial product showed that the LD50 was more than 2,000 mg/kg. Based on the above results, CiO and LO have antibacterial, antioxidant, and termite repellent activities. Therefore, both compounds could be potential termites repellent reagents.

OBJECTIVE: There are various surgical approaches to far-lateral lesions in the L5-S1 intervertebral space. Of these is the validity of a paramedian tangential approach is being investigated in this study. METHODS: A retrospective study was conducted on 25 patients who had been diagnosed as having a far-lateral L5-S1 disc herniations, osteophyte, costal process hypertrophy, and had undergone a paramedian tangential approach from November 1999 through December 2003. The degree of symptoms and improvement were compared via the visual analog pain scale, before and after surgery. RESULTS: This study included 4 males and 21 females with a mean age of 62+/-11.8 years old. The average follow-up period after surgery was 8.2+/-2.7 months. The visual analog pain scale taken before surgery was 6.7+/-1.1 points, while the post-surgical scale was 2.4+/-0.9 points showing a significant decrease (p<0.05). There were no complications that developed during surgery. CONCLUSION: A paramedian tangential approach is less invasive in the soft tissue than that of the median approach. This approach may effectively reduce nerve root compression and expand intervertebral foramens, and is devoid of the risk of spinal instability after surgery. The authors suppose that a paramedian tangential approach is quite an effective technique to relieve compression in the far-lateral L5-S1 intervertebral space.

PURPOSE: To report a case of conjunctival inclusion cysts on the corneal limbus of a patient with chronic vernal keratoconjunctivitis during 16 months' follow up. METHODS: The patient was a 26 year old male without any specific history of surgery or trauma. Giant papillae, shield ulcers, and Horner-Trantas dots were detected. During the 16 month follow-up, Sodium cromoglycate eye drops and Prednisolone acetate 1% eye drops were given 3 times a day. During this period, conjunctival cysts were detected on the corneal limbus in both eyes. In spite of improvement of the corneal and conjunctival conditions, the conjunctival cysts did not seem to show any specific changes. For relief of foreign body sensation, excision of the conjunctival cysts and giant papillae of the left eye and histopathologic examination of the specimen was performed. RESULTS: On histopathological examination, the conjunctival cysts consisted of nonkeratinizing stratified epithelial cells filled with PAS-positive mucous substance. Inflammatory cells were not found in the vicinity. CONCLUSIONS: Conjunctival inclusion cysts can be seen as an atypical finding of long-standing vernal keratoconjunctivitis. Mechanical friction between the giant papillae and conjunctiva may be a factor in inducing the formation of the conjunctival cysts.
