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.

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.

BACKGROUND: Many of the major life events that appear to affect biologic system and health occur within the context of the family and can have a profound psychosocial and biologic impact on family memebers. So, the present study attempted to examine the relations of family function with stressful life events, depression, and physical and psychological symptoms reported by patients. METHODS: Design : Cross sectional, observational study. Participants : 41 healthy adult males from a family medicine ambulatory care unit in a tertiary hospital located in Guro completed a series of psychometric instruments that include the Family APGAR(Adaptation, Partnership, Growth, Affection, and Resolve), FACESIII(Family Adaptability and Cohesion Evaluation Scale), Modified 46-item Stressful Life Events Scale, Lee's 98 items Stressful Life Event Scale, Korean version of BEPSI(Brief Encounter Psychosocial Instrument) and BDI(Beck's Depression Inventory Scale). RESULTS: Family APGAR was negatively correlated with stress related life events(both in total and negative events, -0.30, -0.37, respectively; p<0.05) and BEPSI(-0.56; p<0.0001). No significant correlation could be found between family function and positive life events. Family APGAR also revealed significant negative correlation with BDI(-0.61; p<0.0001). Among the three family types, severe dysfunctional family demonstrated highest level of stressful life events score, perceived stress, and depression(p<0.05). CONCLUSIONS: The higher the assessment of the family function(Family APGAR), the lower the level of stressful life events, perceived stress and depression. There, knowledge of the family function, stress, and coping could be useful to family physicians in the whole person approach of their patients.

This experiment was aimed to investigate the contractile responses of the fermoral artery to the electrical stimulation and the inhibitory effects of verapamil and papaverine on the electrical stimulation of the fermoral artery in the control (n=46) and the diabetic rabbits(n=40). Diabetic rabbits were made by and administration of alloxan (100 mg/kg) intravenously and sacrified 8 weeks later. Femoral arterial rings 3 mm in length were taken and mounted on the force-displacement transducer for the measurements of isometric tension. All experiments were done in the aerated (95% O2 with 5% CO2)biological chamber filled with Kreb's solution and the initial tension of 1.5g was applied to the rings. After 1 hour of equilibrium of the rings, the contractile responses of the electrical stimulation on the femoral arterial rings were taken without vasoactive drugs and then, under verapamil and papaverine solution. And we compared the morphologic findings of the vessels in the two groups in relation to the functional changes by transmission electron miroscopy. The results are as follows: 1. The contractile responses in the presence of verapamil or papaverine solutions to the electrical stimulation were lowed significantly in the fermoral arterial rings of the diabetic rabbits compared with that of the control rabbits (verapamil; 10M~10M: p<0.01, papaverine; 10M & 10M: p<0.01). 2. Transmission electron microphotographs showed many morphological differences of the femoral arteries between the control and the diabetic rabbits. These were irregularities of the internal elastic lamina and the hypertrophy of the cytoplasms of the smooth muscle cells. And also, there were many vacuoles in the cytoplasm of the endothelial cells, lateral to the internal elastic laminaes, and between the smooth muscle cells in the diabetic rabbit femoral artery. By this study, we found that the contractile responses of the femoral arterial rings to the electrical stimulation were decreased in the diabetic rabbits, and the vasodiatory effects of verapamil and papaverine on the electrically stimulated femoral arterial rings were also lowered in the diabetic rabbits compared with the control rabbits. These changes of the vasular responses of the diabetic vessel may be associated with morphological changes manifested by transmission electron microscopy or any other functional derangement of the vessels.

Accessory auricle is a relatively rare congenital anomaly arised from the abnormaI development of the auricular tubercles or from the tissues surrounding the second, third and fourth branchial clefts. Clinically this anomaly is a small akin-colored tag or nodule, soft and globular or cartilaginous consistency on or near the tragus along a line drawn from the tragus to the angle of the mouth or along the anterior margin of the sternomastoid muscle. The lesion is usually solitary and located in the preauricular area but may be multiple and rarely bilateral. We present a typical caae of accessory auricles in 4-day-old female infant. The patient had two skin-colored firm nodules on the left preauricular area and well pedunculated one on the Ieft buccal area near the angle of the rnouth. Histopathologic find.ings showed numerous pilosebaceous units, abundant subcutaneous fat and cartilage tissue in the center of the lesion.

Among the causes of pure red cell aplasia, human parvovirus B19 has been shown to be cytotoxic to erythroid progenitor cells in the bone marrow associated with chronic hemolytic anemia with rapidly dividing erythroids and persistently to be suppression of erythropoiesis in immunocompromised individuals related with failure to produce neutralizing antibody to the virus. In a patient with hereditary spherocytosis presenting acute onset of reticulocytopenia during hospitalization, who had shown severe anemia and prodromal symptoms including fever, fatigue and dizziness, infection of parvovirus Bl9 was proven by the presence of IgM and IgG antibodies to parvovirus Bl9, the detection of viral DNA using PCR technique in her serum and the decreased erythroid cells, especially late normoblasts in bone marrow, Also in the other who was diagnosed as hereditary elliptocytosis and complained of fever, headache, abdominal pain and diarrhea, an episode of reticulocytopenia and the nearly absence of late normoblasts in the bone marrow were observed. IgM antibodies to parvovirus Bl9 and the viral DNA were detected in her serum, too.
