Drowning is a leading cause of accidental deaths worldwide, but its pathological diagnosis remains a challenge for forensic pathologists owing to a lack of pathognomonic findings in drowning deaths and inconclusive autopsy findings caused by postmortem changes. The aim of the present study was to investigate the pathway taken by inhaled drowning medium through the airway after death in a variety of experimental conditions, including underwater pressurization. We used methylene blue dye to monitor the spread of drowning medium to the lungs. Results of theses experiments demonstrated that it is possible for a significant amount of downing medium to enter the airway during immersion after death. Our results suggest that autopsies of immersed bodies and interpretation of these findings should be performed with special care.

Annals of Dermatology 1991;3(1):54-57
Sweet's syndrome is an important cutaneous sign of underlying myeloproliferative disorder. The majority of cases have occurred with acute leukemia, primarily of the myelogenous type. We described a case of Sweet's syndrome in a patient with myelodysplastic syndrome that preceded acute myelogenous leukemia by 9 months.

Malignant pyoperma is a rare, chronic, progressive, destructive ulcerating skin disease of unknown cause that affects the head and neck region of young adults. The disease is progressive but responds to high doses of systemically administered steroids. We present a case of malignant pyoderma developed on the left retroauricular area in 67 year-old male. The patient died of rapidly progressive, desructive, 15cm x 20 cm sized, phagedenic ulcer on the left retroauricular and neck area despite of various extensive local and systemic treatment. Histopathologic findings of tissue from the edge of the ulcer were non-specific, showing upper dermal necrosis and mixed inflammatory cell infiltrate in the deep dermis.

This study was undertaken to investigate the effect of superoxide dismutase(SOD) to sunburn cell production and development of UV-induced ear swelling reaction in mouse skin after ultraviolet irradiation. In this study, a total of 60 ICR female albino haired mice were used and divided into two groups, A(UVB: 150mJ/cm) and B(UVB:300mJ/cm). Groups of mice were injected intravenouly with SQD(300mJ,/1000cm) just befare UVR and after completion of UVR. The results were as follows . 1. The number of sunburn cells was significantly decreased by injection of SOD (300ug.1000ug)(p<0.05). 2. The number of sunburn cells in a group of mice which was given SOD 1000ug was significantly decreased more than in SOD 300pg(p<0.05). 3. Ear swelling reaction was not significantly suppressed by injection of SOD(300 Pa. 100SC)(p<0 05)

Generalized lipodyst,rophy is characterized by generalized loss of body fat, and is asociated vith metabolic ahnormalities, including insulin resistance, hyperglycemia., and hypertriglyceridemia. like acanthosis nigricans, generalized lipodystrophy is a cutaneous marker of insulin re.istant diabetes. We report. herein a twenty year old female witti both classic generalized lipodystripin and acanthosis nigricans, in association with insulin resistant diabetes.

Persistent light reaction, actinic reticuloid, photosensitive eczema are three chronic photodermatoses with a feature of clinical, histological, and photobiologieal characteristics in common. These conditions were given the name of chronic persistent photosensitivity. Chronic persistent photosensitivity with the feature of photosensitive eczema developed in a 68-year-old male patient who had experienced persisited dermatitis. On phototesting the patient showed extremely severe photosensitivity to the short wave UVB. A skin biopsy showed microscopic finding of eczematous dermatitis.

Mitral valvular orifice area is important for the evaluation of prognosis and treatment of patients with mitral valvular stenosis. Until recently, Gorlin's formula using cardiac catheterization has been utilized in the measurement of mitral valve area, but it is invasive and impractical to examine repeatedly. Recently 2-Dimensional echocardiography appeared to be a practical and useful substitute in measurement of valve area and also it is economical and has no risk to patients. In 31 patients with mitral valvular stenosis examined at the echocardiography room of Busan national University Hospital from March 1982 to March 1983, we measured the mitral valve area with 2-Dimensional echocardiography and evaluated its relationship with the left ventricular functions measured on M-mode echocardiogram. Among many parameters on M-mode measurements EF slope, excursion amplitude and the ratio of left atrial dimension to aortic root dimension were rather helpful for the assessment of severity of mitral valvular stenosis than other parameters. And each relationship with the valve area showed correlation coefficient of 0.60, 0.05 and -0.58, respectively.
