Trichoadenoma is a rare, benign, cutaneous tumor with differentiation towards the infundibular portion of the pilosebaceous canal. Clinically, it occurs as a solitary tumor, and most commonly on the face. Histologically, it is characterized by numerous horn cysts lined with squamous epithelium and solid tumor islands in the dermis. A 25-year-old female patient presented with a solitary 0.7x0.7cm sized, skin-colored, central, depressed papule on the right cheek, which had been present for 7 years. Histopathologic findings showed the characteristic features of trichoadenoma.

Transcutaneous electrical nerve stimulation(TENS), acupuncture-needling, and electroacupuncture are useful non-ablative methods in medical practice for relief of pain. These procedures appear to work by causing an increased discharge in afferent nerve fibers which in turn modifies the transmission of impulses in pain pathways. It is known that the mechanism of analagesic effect via these maneuvers are variable depending on the stimulating parameters. For example, the endogenous opioid system is profoundly related to the mechanism when a peripheral nerve stimulation is applied with parameters of low frequency and high intensity. However, when stimulated with parameters of high frequency and high intensity, the reduced activity of dorsal horn neurons is only slightly reversed by a systemic administration of naloxone, a specific opiate antagonist. Thus, the present study was performed to investigate the neurotransmitter that concerns the mechanism of peripheral nerve stimulation with parameters of high frequency and high intensity. We used an iontophoretic application of antagonists of possible related neurotransmitters. The dorsal horn neuron activity which was evoked by squeezing the peripheral cutaneous receptive field, was recorded as an index of pain with a microelectrode at the lumbo-sacral spinal cord. Naloxone, picrotoxin and strychnine were applied at 200nA during a period of conditioning nerve stimulation. We observed the effects of these drugs on the change of dorsal horn neuron activities. The main results of the experiment can be summarized as follows. The spontaneous activity of dorsal horn neurons increased in the presence of glutamate and decreased with GABA. It did not change with naloxone, picrotoxin or strychnine. When naloxone was applied iontophoretically during peripheral nerve stimulation, there was no statistically significant analgesic effect compared with that of the control group. When picrotoxin was applied iontophoretically during peripheral nerve stimulation, the analgesic effect was reduced. When strychnine was applied, the analgesic effect was reduced but did not show a statistically significant difference with the control group. These results suggested that the GABAergic system may have been partially related in the analgesic action of peripheral nerve stimulation with parameters of high frequency and high intensity.

BACKGROUND: Our aim was to make a comparative analysis of radiological and clinical outcomes of using either one or two interlocking distal screws on a Polarus intramedullary nail for the internal fixation of humeral shaft fractures. METHODS: From January 2008 to March 2014, we enrolled 26 patients with humeral shaft fractures who were operated on using intramedullary nails. The patients were divided into 2 groups according to how many interlocking distal screws were used to lock the Polarus nail: in group 1, a single interlocking distal screw was used in 12 patients; and in group 2, double interlocking distal screws, in 14 patients. We compared the degree of recovery of the displaced fracture fragments between the two groups. To compare the nonunion and shoulder function, we assessed each patient's modified American Shoulder and Elbow Surgerns (ASES) score. RESULTS: We found that 10 of 12 fractures achieved union in group 1, and 13 of 14 fractures, in group 2. We did not find a meaningful difference in the time to bone union between the two groups. The percentage of recovery of displaced fracture fragments until union was 66.9% for group 1 and 59.41% for group 2. At the final follow-up, we found that the scores for shoulder joint modified ASES was 78.7 for group 1 and 80.7 for group 2. CONCLUSIONS: Our results show that if locked appropriately, even a single screw on a Polarus nail can provide satisfactory radiological union and improved clinical outcome after intramedullary nailing of humeral shaft fractures.

PURPOSE: Odontoma is a benign tumor originating from odontogenic tissue without any specific cause. Odontoma is usually found in people in their first and second decades of life. It generally exists along the dental arch of maxilla and mandible in the intraosseous location and rarely extends into maxillary sinus. The purpose of this report is to report a rare case of compound odontoma which extended into maxillary sinus. METHODS: We experienced a compound odontoma extending into maxillary sinus with swelling on upper labium in 21-year-old man. RESULTS: The excised tumor was 2.3x1x1cm sized and was confirmed as compound odontoma by the histological examination. CONCLUSION: We report this rare case of compound odontoma extending into maxillary sinus and having swelling of upper labium.

PURPOSE: Elderly patients of colorectal cancer compose a steadily expanding portion of the population in Korea. The decision whether or not to operate on elderly patients who have carcinoma of colon and rectum is often unduly complicated. The aim of this study is to evaluate the results of the operations for colorectal cancers in the elderly. METHODS: This report is a retrospective clinical analysis for 365 cases of colorectal cancer who were treated surgically at the Department of surgery, Chonbuk National University Medical School from January 1994 to December 1998. To evaluate the age factor in colorectal cancer, the patients were divided into two groups: The elderly group included 79 patients who were aged > or =70 years on first presentation; The control group comprised 286 patients aged <70. RESULTS: There is no significant difference between the two group with regard to the mode of presentation, gender, location of tumor, clinical symptom and sign, duration of symptom, coexistent disease, operation method, tumor size, histopathologic findings, the Astler-Coller classification, lymphatic and distant metastasis, perioperative complication and 5-year survival. The emergency operation is significantly higher incidence in the elderly group. CONCLUSIONS: It is concluded that surgical resection of colorectal cancer in elderly is standard method and should not be restricted on the basis of age alone.
