Sulfuric acid can cause local or systemic effects after exposure by inhalation, ingestion, or topical application. Direct ingestion is the main exposure route for fatal sulfuric acid injury. Fatal accidents involving the inhalation of toxic sulfuric acid vapors are rare. Inhalation of sulfuric acid fumes causes severe irritation or corrosive damage to the upper respiratory tract. Consequently, severe congestion, edema, and inflammation of the mucous membranes of the upper respiratory passages hinder the entry of air into the lungs, possibly leading to fatalities in victims. A 35-year-old man died at his home after complaining of a severe sore throat. One day earlier, he had worked in a sulfuric acid tank in a copper-smelting plant while wearing an ordinary gas mask that offered no protection against sulfurous acid vapors. Upon autopsy, the larynx and epiglottis showed pronounced edema, congestion, and inflammation that histologically mimicked an acute bacterial suppurative inflammation, accompanied by severe pulmonary edema. A field analysis of the air inside the sulfuric acid tank revealed SO4(2-) positivity and a 40% sulfuric acid concentration.

Norwegian scabies is a rare clinical variant of human infestation with Sarcoptes sabiei var, hominis, distinguished from the common form of scabies by the presence of remarkable hyperkeratotic scaly crusted skin lesions. We report two cases of Norwegian scabies occuring in a 25-year-old man with merital retardation and in a 9-year-old boy with aplastic anemia, The first case is characterized. by an extensive hyperkeratotic thickening and crusting of the dorsa of hands, knee 8: elbow joints. There is also subungual accumulation of horny rlebris with nail distortion. Histologically, the epidermis shows a mite in straturn comeurn and mild acanthosis in stratum malpighii. Immunoperoxidase for Ig G,M,A is not stained in the clermoepiderrnal junction and capillary wall of upper dermis. The second case shows hyperkeratotic scaly papules and p]aques on the hands, feet, extremities and trunk. 1'he diagnosis vvas confirrned by the demonstration of adults, nymphs, larvas and eggs of Sarcoptes scabiei con the KOH examination of the skin scrapings. hey l3'ords: Norwegian scabies, Mental retardation, Aplastic anemia

A noninvasive method for assessing cardiac output was evaluated by comparing it with thermodilution determinations in 25 patients who admitted to Pusan national university hospital from March, 1985 to December, 1986. This method used M-mode & two dimensional echocardiography to measure the internal diameter of aortic valve anulus & pulmonary valve anulus and pulsed doppler echocardiography to obtain aortic & pulmonary blood velocity. Good correlations were observed between thermodilution and doppler echocardiographic measurements of cardiac output from aortic flow (r=0.98, p<0.05) & pulmonary flow (r=0.86, p<0.05). Linear regression analysis yielded y=0.91x0.14 for aortic flow and y=0.77x0.84 for pulmonary flow. These results indicate that accurate cardiac output can be measured by noninvasive & simple doppler echocardiography.

Synovial sarcoma is a distinct and generally recognized soft tissue tumor that it’s origin still raises controversy. The synovial origin of synovial sarcoma has not been determined despite the accepted terminology implying synovium as stem cell. Three cases of primary synovial sarcoma (2 fibrous monophasic, 1 biphasic type) were studied with a panel of antibodies against different types of cytokeratin and other markers (EMA, CEA, vimentin, S-100 protein, lysozyme, 1-antichymotrypsin). Spindle shaped-cell in monophasic synovial sarcoma showed reactivity for CK7 and pancytokeratin. Epithelial cells lining of glands in biphasic synovial sarcoma reactive for CK7, pancytokeratin, EMA, and focally CEA but spindle cells only positive for vimentin. By electron microscopy, fibrous monophasic synovial sarcoma showed pseudogland formation with intercellular junctions of paired subplasmalemmal destiny and discontinuous basal lamina. These results indicate that synovial sarcoma showes epithelial differentiation. We believe that synovial sarcoma arises in pluripotential connective tissue cells that is able to be differentiated into both mesenchymal and epithelial components. So, synovial sarcoma have been considered carcinosarcoma of soft tissues depending on the type of differentiation.
