Sleep changes substantially with age. There is a phase advance in the circadian sleep cycle and increased waking after sleep onset. The elderly people wake more frequently during the night and experience fragmented sleep and excessive daytime sleepiness. The prevalence of sleep disorders increases with age, and the composition of sleep disorders in the elderly differs from that in the young. The most frequently encountered sleep disorders are psychophysiologic insomnia, sleep disturbance due to dementia, sleep-related respiratory disorder, restless legs syndrome and periodic limb movement disorder, and REM sleep behavior disorder. To treat the elderly sleep problem appropriately, it is important to know how sleep pattern changes as we age and to understand the cause of sleep-related symptoms. This article will review the sleep physiology and common sleep disorders in the elderly.

Excessive daytime sleepiness in childhood might be abnormal phenomenon and often related to the sleep disorders or insufficient sleep duration. The most common cause of excessive daytime sleepiness would be insufficient sleep. However, narcolepsy, idiopathic hypersomnia, circadian rhythm sleep disorders, medication, medical illness and other sleep disorders that could cause insomnia and poor quality of sleep also result in excessive daytime sleepiness. The misdiagnosed and untreated excessive daytime sleepiness in childhood can lead to serious developmental and educational problem.

This article presents a description of the ultrasonographic and computed tomographic findings with a discussion on the imaging features in three patients with epigastric hernias, simulating abdominal wall lipomas. Ultrasonogram showed a heterogeneous hypoechoic mass encircled by echogenic rim within subcutaneous space of the abdominal wall. Computed tomographic findings were a localized fatty mass surrounded by a thin capsule in as sociation with a focal discontinuity of the linea alba. Ultrasonogram was not diagnostic, but computed tomogram was suggestive because of the well demonstrated focal defect in linea alba.

BACKGROUND: Hydrofluoric acid(HF) is one of the strong stirritating, corrosive and poisonous inorganic acid, The HF burns are occuring with ever-increa firifrequency due to the wide use of this acid in industrial fields, such as electronics and semicor tor industries. OBJECTIVE: The purpie of this study is to quantiate theound depths produced by varying concentrations of HF aiud to suggest the treatment guideline. METHODS: Uarious cinicentrations of HF(5%, 25%, 50%),were applied to two pairs of test sites on a guinea pig's back in a uniform fashion with cotton-tip applicators and then the histopathologic changes of guinea pig skin were observed. RESULTS: 1, In the 5% HF applied group, intracellular edema vaobserved in the epidermis after 12 hours. After 3days, epidermal cell necrosis was observed. 2. In the 25% HF applied group, intraepidermal vesice was observed after 6hours. After 12hours, inflammatory cell infiltrations were observed in the apper dermis and then after 3days, dermal necrosis was oberved. 3. In the 50% HF applied group, epidermal cell necros After 6hours, liquefaction degeneration in the epidermis an was observed focally after 3hours. iflhmmatory cell infiltrations in the upper dermis were observed. After 2days, dermalar.ecrosis was observed and then after days, the reaction was at its peak and subcutaneous tissuc. necrosis was observed. CONCLUSION: This study showed that a higher concentrator HF exposure enhances The penetration of HF. For treatmi not alcohloic solution of a quarternary ammonium for avintralesional injection of calcium gluconate within 24 hours of HF and a longer period after we suggest wet dressing with an concentration of HF burn and high concentration of HF burn.
