BACKGROUND: A majority of patients undergoing chemical peeling complain of pain severe enough to disturb the process of the peeling. However, there has been few controlled studies on pain control during chemical peeling. OBJECTIVES: We evaluated the efficacy and safety of pretreatment with intramuscular ketorolac (Tarasyn, 30 mg) and oral diazepam(Valium, 5 mg) in comparison with control and diazepam groups, and compared the sensitivity of pain between two sexes. METHODS: The patients were randomly assigned to one of three groups; control, diazepam, and ketorolac plus diazepam groups. Pain intensity was assessed 5 times at every ten minutes from the beginning of the peeling using visual analog scale(VAS). RESULTS: At every 10 minutes of pain assessment, ketorolac plus diazepam group recorded the lowest VAS among the three groups. Except at the first 10 minutes, nificant. There was no significant difference in the pain intensity between the sexes at all five times. After application of Jessner`s solution, there was significant increase of VAS in all groups. CONCLUSION: The ketorolac pretreatment is a safe and effective modality of pain relief prior to chemical peeling without the adverse reactions.

A case of metastatic adenoid cystic carcinoma of the lung, originated from the trachea, was diagnosed by fine needle aspiration. Although the cytologic features of adenoid cystic carcinoma have been well described, it is easy to confuse adenoid cystic carcinoma with more common primary small cell neoplasms of the lung, i.e., small cell carcinoma, well differentiated adenocarcinoma, and carcinoid tumor of the lung. The features distinguishing adenoid cystic carcinoma from these neoplasms include 1) tight, globular, honeycomb pattern of cells, 2) acelluair basement membrane material in the lumen, and 3) cells lacking true nuclear molding and having bland chromatin pattern. The mcrphologic feature of metastatic adenoid cystic carcinoma in this case was so distinctive as to permit a definite diagnosis by aspiration cytology.

Bone metastasis of hepatocellular carcinoma appears to be peculiar when clinical manifestation of liver disease is not apparent, and initial diagnosis of metastatic hepatocellular carcinoma by fine needle aspiration cytology is rarely obtained. We experienced a case of 45-year-old man with metastatic hepatocellular carcinoma in the sacrum, which was diagnosed by fine needle aspiration cytology. The intrahepatic mass, measuring 1.2cm in diameter and kept unchanged in size for two years, was never proved to be hepatocellular carcinoma histopathologically. The aspirated neoplastic cells were mostly in sheets, showing abundant acidophilic cytoplasm and large, round, centrally located nuclei with single, prominent acidophilic mucleoli. In the cell block section, diagnosis of metastatic well-differentiated hepatocellular carcinoma was made without difficulty, and definite trabecular fashion with sinusoidal endothelial cell lining was found.

BACKGROUND: A few studies have revealed increased levels of certain cytokines in patients with ischemic stroke. Cytokine changes have not been studied in patients with transient ischemic attack(TIA). The purpose of this study was to evaluate the temporal profile of the inflammatory response in patients with vertebrobasilar insufficiency (VBI) and to compare the inflammatory response between TIA and infarction through analyzing serum interleukin(IL)-6 and IL-10. METHODS: We serially measured the serum levels of IL-6 and IL-10 in 14 patients with VBI, 12 patients with vertebrobasilar territoy infarction, and 21 patients with lacunar infarction at the timing of admission, at 1 day after symptom onset, and at 5 day after symptom onset. Cytokines were measured by sandwich ELISA method. RESULTS: The IL-6 level obtained at day 1 was significantly elevated compared with the normal control group in patients with TIA (p<0.05). The IL-6 level at day 1 was the highest in patients with VBI. The level of IL-10 in patients with VBI was significantly higher than normal group at all time points(p<0.05). The IL-10 level at the timing of admission was the highest in patients with VBI. But the serum levels of IL-6 and IL-10 between VBI and vertebrobasilar territory and lacunar infarction groups did not show any differences. CONCLUSION: These findings show that pro- and anti-inflammatory cytokines in serum are elevated in patients with TIA. These results suggest that cytokine cascade occurs in TIA.

Friction melanosis (FM) is an acquired pigmented disease that is caused by recurrent mechanical stress. There is no previous report explaining the presence of tiny brown-colored particles confined to the corneal layer. We describe a case of a rare form of FM of the finger that showed a relatively transient clinical course. A 17-year-old Korean female presented with a 5-month history of an asymptomatic localized hyperpigmented patch on the tip of the right index finger. The dermoscopic examination revealed homogenous globular pattern, which favored pigmentation over hemorrhage. Histopathologically, hyperkeratosis and acanthosis with lymphohistiocytic infiltration of the superficial dermis were noted on hematoxylin and eosin staining; however, there was neither a definite increase in melanophages in the upper dermis nor melanocytic proliferation in the basal layer. Per high-power field, multiple brown-colored tiny particles were scattered in the corneal layer. The particles were not dyed by Fontana-Masson stain, iron stain, and S-100. We questioned the patient about the presence of irritation and found that she had bought new shoes at the time of the onset. She was habituated to placing her fingers in her shoes while wearing them because they were slightly tight. The lesion disappeared spontaneously a week after the cause of friction was eliminated.Altogether, we encountered a rare form of FM that occurred in a rare location with a transient clinical course. Further cases on pigmentation restricted to finger tips might reveal the origin of the particles.
