Toxic epidermal necrolysis(T.E.N.) is a toxic erythema of the skin that undergoes epidermal necrolysis and peding so that it appears to have been scalded. There seem to be two basic form of T.E.N. In children, the deavage of the epidermis that results from an acantholytic-dyskeratotic cytolytic process is in the malpighian or granular layer and is usually induced by a staphylococci toxin. In adult, it is characterized by a full-thicknees cytolytic cleavage of skin above the basal layer and is usually precipitated by a drug. The authors observed a 17 year-old male with T.E.N. He began to notify the erythematous skin lesion with burning sensation on the whole body surface at 12 hours after oral administration of some drugs for common cold and developed the characteristic flaccid bullous and denuded lesions with tenderness within next 20 hours.

The changes of electroencephalogram(EEG) in patients with dementia are most commonly studied by analyzing power or magnitude in certain traditionally defined frequency bands. However because of the absence of on identified metric which quantifies the complex amount of information, there are many limitations in using such a linear method. According to chaos theory, irregular signals of EEG cal also result from low dimensional deterministic chaos. Chaotic nonlinear dynamics in the EEG can be studied by calculating the correlation dimension. The authors have analyzed EEG epochs from three patients with dementia of Alzheimer type and three matched control subject. The result showed that patients with dementia of Alzheimer type had significantly lower correlation dimension than non-demented controls on 12 channels. Topographic analysis showed that the correlation dimensions were significantly lower in patients with Alzheimer's disease on frontal, temporal, central, and occipital head regions. These results show that brains of patients with dementia with dementia of Alzheimer type have a decreased complexity of electrophysiological behavior. We conclude that the nonlinear analysis such as calculating correlation dimension can be a promising tool for detecting changes in the complexity of brain dynamics.

Nevus Iipomatosus cutaneous superficialis (NLCS) is a very rare skin disease which usually is present at birth. The lesion consists of grouped papules and nodules which on histological examination show the presence of ectopic fatty tissue in the corium. The authors observed a 17year old female with NLCS. She noticed soft papules and nodules on the coccygeal area since 8 years old. We confirmed this case by clinically and histopathological findings which showed the strands or islands of mature fatty tissue within papillay, mid and lower dermis.

Here, a case of a 59-year-old man with rotator cuff tear and impingement syndrome caused by an ossified coracoacromial ligament is presented. Ossification of the coracoacromial ligaments can occur because of degenerative changes due to trauma or repeated stress, which can lead to impingement syndrome. Therefore, when coracoacromial ligament ossification is present, rotator cuff damage due to impingement syndrome should be considered. Here, we conducted arthroscopic subacromial decompression, removal of the ossified coracoacromial ligament, and supraspinatus and subscapularis tendon repairs. We achieved satisfactory surgical outcomes without relapse; therefore, we report this case with a literature review.

BACKGROUND: Hypertonic solutions are using in emergency patients including refractory shock. The effects of the hyperosmotic solutions for the cardiac contractile effect has remained unclear. To study the mechanism of increase in twitch force by hypertonic solution, memberane potential, intracellular sodium activities(aNia), and twitch force were measured simultaneously in 1 Hz-driven canine Purkinje fibers and guinea pig papillary muscles. METHODS: To increase osmolarity, 20, 40, and 80 mOsm glucose, NaCl or mannitol was added to normal Tyrode solution. We used the conventional and Na(+)-selective microelectrodes, to study the membrane potential and intracellular sodium activity. Changes in twitch force were evaluated also by tension tranducer. RESULTS: 1) Hyperosmolar glucose or NaCl added to normal Tyrode solution produced membrane pontential hyperpolarization, increase in aNia, and increase in twitch force in dog Purkinje fibers. Increase in twitch force was related to decrease in the ratio of aNia to extracellular sodium activity(aNoa). NaCl-inducedd aNia increase was not blocked by 10(-5)M tetrodotoxin, a fast sodium channel blocker. 2) Hyperosmolar glucose or mannitol added to normal Tyrode solution produced membrane potential hyperpolarization, increase in aNia, and increase in twitch force in guinea pig papillary muscles. However, the addition of hyperosmolar NaCl did not affect on membrane potential, but produced increase in aNia, and decrease in twitch force. 3) Prolonging effect of hyperosmolar glucose on duration of action potential was smaller than that of NaCl or mannitol in Purkinje fibers and papillary muscles. 4) Increase in twich force produced by ECF Na+reduction or by hyperosmotic solution was reated to decrase in the aNia ratio. 5) Relationship curve between increase in twitch force and aNoa/aNia ratio in hyperosmolr solution was less steeper than that in ECF Na(+)-reduced solution. CONCLUSION: The above results suggested that hyperosmolar solution-induced twitch force change was related to aNoa/aNia ratio change which influenced intracellular calcium activity via Na(+)-Ca(2+)exchange.

Hemosiderosis is a disorder characterized by deposits of hemosicerin in multiple organs without organ dysfunction or injury. The color of the skin becomes brown, espeially on sun exposured areas. Mucous mernbranes are also affected in up to 5-25% of cases. A 43-year-old woman visited our clinic due to generalized brown colotation of her skin, including conjunct we and oral mucous mernbrane which she had had for 10 months. She had been treated with multiple he nodialysis combined with periodic transfusion for renal failure 3 times a month during the last 5 yeadrs Her plasma ferrit in level was elevated markedly and TIBC decreased, but cortisol and ACTH levels were within normal limits, Histopathologic findings of the neck skin showed hyperpigmentation of basal layer and deposition of brown pigment wrthin and around the sweat glands. In Fontana-Masson stain, the lower epidermis showed a massive deposition of melanin. Prussian blue stain revealei hemosiderin within snd around, the sweat glands. Hemosiderin could also be noticed on specirnens of thliver biopsy. The patient improved progressively after the rstriction of trasnfusion and treatment of renal failure.
