A bronchogenic cyst is an uncommon benign congenital anomaly of the primitive ventral foregut. Although bronchogenic cysts in the midline of anterior neck have been reported, they are known to occur very rarely. Moreover, it has never been reported to be located submentally in adults. Clinically, it is usually asymptomatic and thus incidentally diagnosed. Radiologically, it can not be differentiated from other cystic lesions. Therefore, it is pathologically confirmed only when there are bronchial tissues such as pseudostratified ciliated columnar epithelium, smooth muscle, mucous gland or cartilage. Since this cyst has potential for complication, a complete excision is mandatory. We recently experienced a case of bronchogenic cyst presenting as a submental mass in a 26 year-old man. In this article, we reviewed the etiology, the diagnosis, and the treatment of this case with a review of the literatures.

Sacrococcygeal teratoma is a rare tumor, it occurs once in every 40,000 live births. Most of the reported cases appear in female infant (M:F=1:4). They deserve clinical attention because they are potentially malignant and are curable if diagnosed and treated early. The patients may have associated congenital anomalies. This patient has spina bifida cystica in lower sacrum. Brief review of related literature is included in the report.

PURPOSE: Sleep deprivation may exert many negative effects on hippocampus-dependent cognitive function, such as learning and memory. The present study was conducted in order to investigate the effects of repetitive sleep deprivation on cognition, apoptotic neuronal cell death, and cell proliferation in the hippocampus, using mice. METHODS: To induce sleep deprivation, mice were placed in a water cage containing six platforms (3 cm in diameter), surrounded by water up to 1 cm beneath the surface of the platform for 24 h. Mice were randomly divided into four groups (n=20 in each group): control group, 24 h rest after 24 h sleep deprivation group, 48 h rest after 24 h sleep deprivation group, and 72 h rest after 24 h sleep deprivation group. This cycle was continued for 36 days. Novel objective recognition test and immunohistochemistry for 5-bromo-2'-deoxyuridine (BrdU), western blot for expression of Bax, Bcl-2, brain-derived neurotrophic factor (BDNF), and caspase-3 were performed. RESULTS: Results of the novel objective recognition test showed decreased cognition in the 24 h rest after 24 h sleep deprivation group, while a similar effect was observed in other groups, compared to the control group. Increased cell proliferation and enhanced expression of BDNF and Bax protein were observed in the 24 h rest after 24 h sleep deprivation group and the 48 h rest after 24 h sleep deprivation group, compared to the control group. Expression of Bcl-2 showed a decrease in the 24 h and 48 h rest groups, compared to the control group. Expression of caspase-3 in the dentate gyrus of the hippocampus showed a significant increase in the 24 h rest after 24 h sleep deprivation group and in the 48 h rest after 24 h sleep deprivation group, compared to the control group. CONCLUSION: Results of the present study indicate that insufficient rest after sleep deprivation may induce impairment of cognitive function. After sleep deprivation, at least 72 hr of rest time is needed for recovery.

PURPOSE: The purpose of this study was to investigate the relationship between suicide risk factors and psychiatric disorders, and between suicide risk factors and suicide attempts after discharge, and to analyze the necessity of a psychiatrist referral in patients who intentionally ingested drug but did not make a suicide attempt. METHODS: Between January 1, 2004 and December 31, 2008, we investigated cases of intentional drug ingestion in patients greater than 15 years of age who visited Kyung Hee University emergency medical center. We divided the patients into two groups - a suicide attempt group and a non-suicide attempt group. The difference between suicide risk factors of the two groups was investigated prospectively. Among the risk factors for suicide, we determined whether psychiatric diagnosis was highly associated with suicide and whether it was an influential factor in suicide attempts after discharge. SPSS version 13.0 was used for statistical analysis. Chi-square, paired sample t-test, and Fisher's exact test were performed, and a p<0.05 was considered to be statistically significant. RESULTS: There were no significant differences in suicide risk factors between the two groups (p>0.05). Patients who did not attempt suicide who had a psychiatric history associated with suicide attempts, who had previous suicide attempts, who had a family history of suicide, and who lived alone, may have psychiatric disorders associated with suicide or suicide attempt after discharge (p<0.05). CONCLUSION: All patients who intentionally ingested drugs should be given a psychiatrist referral, even if the patients did not attempt suicide. In particular, the psychiatric referral should be made when the patient has risk factors such as a psychiatric history associated with suicide attempts, previous suicide attempts, a family history of suicide, and living alone.

Malignant rhabdoid tumor was first discovered in the kidney, and rhabdoid tumor of the lung was first reported in 1995. These were included as the variants of large-cell carcinoma, according to the 1999 World Health Organization classification of lung tumors. The rhabdoid tumor of the lung exhibits aggressive biological behavior and has a poor prognosis, and only a few reports of this tumor exist. We report a case of lung carcinoma with a rhabdoid phenotype, initially misdiagnosed as an aspergilloma, in a 48-year-old man who presented with recurrent hemoptysis. The chest computed tomography scans showed a huge consolidative lesion with an air crescent sign in the left upper lung and no contrast-enhancing lesion. An aspergilloma was diagnosed by the radiologist. However, after surgical excision and pathological examination, rhabdoid carcinoma was diagnosed. A surgical resection helps to make it possible to pathologically distinguish a malignancy from an aspergilloma.

Esophageal granular cell tumor (GCT) is a rare neoplasm originating from the Schwann cells of the submucosal neuronal plexus. Histology is the gold standard for its diagnosis. Endoscopic resection or surgical excision should be considered, depending on the potential for malignancy. Here, we report a case of an esophageal GCT in an adolescent. A 12-year-old boy presented with a 1-year history of dysphagia and vomiting. Upper gastrointestinal endoscopic examination and esophagography showed narrowing of the midesophagus, and computed tomography angiography of the thoracic aorta revealed an esophageal or periesophageal mass posterior to the paratracheal segment of the esophagus. The tumor was surgically excised, and based on the pathological findings, esophageal GCT was diagnosed.

BACKGROUND: We conducted an experimental study to compare the effect of massage using topical agents (Kelo-cote or Contractubex) on scar formation by massaging the healed burn wound on the dorsal area of Sprague-Dawley (SD) rats. METHODS: Four areas of second degree contact burn were made on the dorsal area of each of 15 SD rats, using a soldering iron 15 mm in diameter. After gross epithelialization in the defect, 15 SD rats were randomly divided into four groups: the Kelo-cote group, Contractubex group, Vaseline group, and control group. Rats in three of the groups (all but the Control group) were massaged twice per day for 5 minutes each day, while those in the Control group were left unattended. For histologic analysis, we performed a biopsy and evaluated the thickness of scar tissue. RESULTS: In the Kelo-cote and Contractubex groups, scar tissue thicknesses showed a significant decrease, compared with the Vaseline and control groups. However, no significant differences were observed between the Kelo-cote and Contractubex groups. In the Vaseline group, scar tissue thicknesses showed a significant decrease, compared with the control groups. CONCLUSIONS: The findings of this study suggest that massage using a topical agent is helpful in the prevention of scar formation and that massage only with lubricant (no use of a topical agent) also has a considerable effect, although not as much as the use of a topical agent. Thus, we recommend massage with a topical agent on the post-burn scar as an effective method for decreasing the scar thickness.
