The aim of this study was to determine whether pattern-reversal Visual Evoked Potential (PRVEP) is affected in mild cognitive impairment (MCI). Participants aged ≥ 60 years diagnosed as MCI were invited to participate in a study together with a group of controls. PRVEP was measured using A RETI-port/Scan 21 and stimuli of large and small checks sizes, 1° (60 min of arc) and 0.25° (15 min) respectively were used to obtain responses. The amplitude and implicit times of the MCI and control groups were then compared. A total of 18 MCI participants (age 65.7 ± 3.1 years) and 18 controls (65.1 ± 3.8 years) consented to participate in the study. The amplitude and implicit times for the MCI group using the target sizes of 60 min of arc were 9.80 ± 4.06 μV and 108.83 ± 7.63 ms and for 30 min of arc were 11.00 ± 7.44 μV and 123.96 ± 6.18 ms respectively. Consecutively for the control groups the amplitudes and implicit times were 8.96 ± 3.52μV, 105.85 ± 3.60 ms and 11.97± 6.11 μV, 122.57 ± 8.28 ms. PRVEP results did not reveal significant differences in P100-wave amplitude nor implicit time between the two groups under investigation. This study concluded that the visual pathway of MCI participants may be unaffected in the early part of the disease process.

Sebaceoma is a benign neoplasm with sebaceous differentiation, and this is characterized by dermal aggregations of basaloid, immature sebaceous cells and sebaceous duct-like structures. Recently, some cases of sebaceoma that presented as a rippled-pattern resembling the palisading of nuclei of verocay bodies have been reported in the English literature. However, there has been no such report in the Korean dermatologic literature. We report here on a case of rippled-pattern sebaceoma that developed in a 78-year-old Korean man.

The study was carried on 3 communes of Giao Thuy district, 2 communes of Xuan Truong district, Nam Dinh province and 3 communes of Dong Hung district, Thai Binh province. The results showed that hemoglobin levels are similar between two genders, reduce gradually consistent with age and are lowest in interior field residents. Total cholesterol level at more than 5.2mmol/l accounts for average of 12.4%; triglycerid level at more than 2.3mmol/l accounts for average of 19.9% and HDL cholesterol at less than 0.9mmol/l makes 26.4%. The rates are highest in older population. These indices have high rate in town areas, followed by coastal areas and lowest in interior field areas. The mean rate of older people who have dyslipidemia is 5.1%.

The tear production of 192 eyes was evaluated by shirmer I and 171 eyes were evaluated by shirmer II among 106 patients (male: 30). The results showed that the average value of total tear production in elderly was 8.7±6.6mm and average value of basic tear production was 6.1±4.3 mm. There was no difference of tear production was reduced with increased ages
