Sebaceous trichofolliculoma, which is a variant of trichofolliculoma, is a rare disease that clinically show a centrally depressed lesion usually singly on the nose, and histologically a centrally located cavity, lined by squamous epithelium, with numerous sebaceous lobules connected to them. We describe a case of sebaceous trichofolliculoma in a 27-year-old woman who had several brown papules on the nose. We think that this is the first report of sebaceous trichofolliculloma in Korean literature.

PURPOSE: To investigate the change in intraocular pressure (IOP) of normal healthy eyes at different positions while performing sit-ups. METHODS: Twenty normal healthy eyes of 20 subjects were studied. IOP was measured while in the 'sitting upright', 'supine', and 'head-down' position to determine postural effect on IOP when executing a sit-up. Measurements were taken after the performance of a sit-up and during the performance of a sit-up, in both the head up and head down positions to test the effect of the exercise on the IOP. In addition, the IOP after an 'isometric exercise with Valsalva's maneuver in the supine or head-down position' was measured to determine the actual IOP during a sit-up. RESULTS: The postural change from sitting upright to tilting the head in a downward position caused the IOP to increase. After the performance of a sit-up, the IOP decreased in both the upright and supine positions, though IOP increased in the head-down position. After the isometric exercise with Valsalva's maneuver, IOP increased significantly regardless of position. CONCLUSIONS: IOP increased significantly during sit-ups, but decreased afterward. Future studies should be performed to evaluate the long-term effects of IOP change during and after sit-ups with respect to the prognosis of glaucoma.

Entrapment of the popliteal artery is a rare cause of ischemia of the lower extremities in young males. The development of local occlusive or aneurysmal changes of the popliteal artery is caused by abnormal anatomical relationships between vascular and musculotendinous structures in the popliteal fossa. A 55-year-old male patient visited Yonsei University College of Medicine with the chief complaint of claudication in his right calf. He had undergone stent insertion in the right popliteal artery for peripheral artery occlusive disease 2 years earlier. Lower extremity CT angiography showed stent fracture and in-stent thrombosis. He underwent femoral-to-popliteal artery bypass surgery. Postoperative lower extremity CT angiography showed that the vein graft was compressed between the medial head of the gastrocnemius and the semimembranosus muscle. However, the blood flow was normal and his pain was relieved.

The aim of this study was to investigate the acute effects of ethanol administration on pattern-reversal visual evoked potential (VEP) and multifocal electroretinography (mfERG). Fifteen healthy subjects with no ocular or general disease were recruited. VEP (0.25° pattern sizes) and mfERG with 19 elements in two recording segments were performed before ethanol administration to obtain baseline for each participant. A few days later, the participants visited again for VEP and mfERG measurements after ethanol administration. Ethanol (0.75 g/kg) was administered orally over the course of 30 minutes. VEP and blood alcohol concentration were evaluated one hour after ethanol administration, and mfERG was conducted after pupil dilation. The Wilcoxon signed-rank test was used to compare parameter changes after randomized eye selection. The mean blood alcohol concentration was 0.034% ± 0.05% by volume. VEP revealed a P100 latency delay (109.4 ± 5.3; 113.1 ± 8.2; P = 0.008) after alcohol administration. The P1 implicit time of ring 1 on mfERG showed a trend of shortening after alcohol administration (37.9 ± 1.0; 37.2 ± 1.5; P = 0.048). However, the changes did not show statistical significance after Bonferroni correction. In conclusion, orally administrated ethanol (0.75 g/kg) appears to suppress the central nervous system, but it is not clear whether alcohol intake affects the retina.

The aim of this study was to investigate the change of microbial contamination levels in the different areas and at the different time points after application of a quaternary ammonium compound (QAC) that has mechanical antimicrobial effect. The microbial contamination levels were measured in three different areas; unit chair handle, spit sink area and hand piece holder at different time points using adenosine triphosphate (ATP) monitoring system and ATP surface test kit. Hand piece holder showed the highest level of microbial contamination. In most of the clinics, QAC significantly reduced the levels of microbial contamination, and maintained antimicrobial activity for 4 to 6 months. QAC may be used effectively in dental clinics due to the duration of antimicrobial effect and the minimal exposure of chemicals and further studies are needed with large sample size.

Ectopic pregnancy and appendicitis in pregnancy are two most common causes of acute abdomen in young women and differenciation of these diseases is very difficult. Heterotopic pregnancy is a rare event, occuring less than 1:30,000 pregnancies in natural conception cycles. However, with assisted reproduction techniques, this incidence has increased. We experienced a case of spontaneous heterotopic pregnancy after missed abortion and acute appendicitis treated by laparoscopy. So we report this case with brief review of literature.

Hypertrophic osteoarthropathy is a syndrome characterized by periosteal new bone formation, arthritis, and clubbing of the fingers and toes. The majority of cases occur secondarily to the conditions associated with pulmonary, cardiac, gastrointestinal disorders or other systemic diseases. There are many cases with malignancy worldwide. We report the first patient who had hypertrophic osteoarthropathy due to metastatic cancer after surgical removal for mucoepidermoid carcinoma of the parotid gland.

Serous cystic neoplasms of the pancreas are almost always benign lesions. However, there are some case reports of malignant serous neoplasms of the pancreas. It is very difficult to distinguish malignant and benign tumors. Indeed, only clinicopathologic findings of locoregional invasion and metastasis represent a malignancy. We report a serous cystadenocarcinoma of the pancreas that was initially considered to be colon cancer. Post-operatively, the tumor was confirmed to be a malignant serous cystic tumor of the pancreas. One year later, the patient remains disease-free.

We here present the case of a 37-year-old woman who suffered from adrenocorticotrophic hormone (ACTH)-dependent Cushing's syndrome due to an olfactory neuroblastoma. The patient's clinical course was complicated by co-infection with cytomegalovirus and Pneumocystis jirovechi, which improved with appropriate antimicrobial therapy and suppression of endogenous steroidogenesis with ketoconazole and octreotide. Radiation to the mass in the nasal cavity resulted in reduction of tumor size and remission of the Cushing's syndrome. This is the first report of the ectopic ACTH syndrome resulting from olfactory neuroblastoma in Korea.

Collision tumor means the coexistence of two adjacent, but histologically distinct tumors without histologic admixture in the same tissue and is rare incidence involving ovary. Because of their incidence of occurrence, benign cystic teratomas often occur coincidentally with other abnormalities of the ovary. Most common histologic combination of collision tumor in the ovary is coexistence of teratoma with mucinous tumors. But its association with serous tumor has been noted rare and incidence is unknown. We have experienced a case laparoscopic treatment of a huge serous cystadenoma combined with ovarian benign cystic teratoma in right ovary, and report it with a brief review of literature.
