Sebaceous adenoma is a benign organoid tumor of proliferating, incornpletely differentiated sebaceous glands. We report a case of sebaceous adenoma in a 15-year-old male. He had a 1.7 x 2.2 cm sized, asymptomatic, srnooth, round, raised, firm, reddish tumor on the left quadrant of abdomen. Histopathologically, the tumor was composed of lobules of irregular size and shape, and sharply demarcated from the surrounding tissue, The most lobules showed undifferentiated germinative and mature sebaceous cells in about equal number. Sebaceous cells in lobules were stained for prekeratin by means of avidin-biotin-peroxidase complex method. Ten months after surgical excision there was no evidence of recurrence.

Partial unilateral lentiginosis(PUL) is a rare pigmentary disorder charaeterized by lentigines limited to one side of the body with or without neurologic abnormalities. We report two cases of PUL unassociated with any other defect, One patient was 20-year-old female who had lentigines confined to the right side of the face and the other was 19-year-old male who had lentigines confined to the left side of the neck and upper trunk and left upper extremity. Histologic examination of the pigmented lesion revealed findings consistent with lentigo simplex.

PURPOSE: There has been little research regarding the effectiveness of oseltamivir for influenza B infections. We sought to identify the different clinical manifestations between patients treated with and without oseltamivir. METHODS: We retrospectively studied the medical records of 72 inpatients or outpatients from two medical centers diagnosed with influenza B infections by either a rapid antigen test or multiplex reverse transcriptase PCR between January 2012 and July 2012. We compared gender, age, past medical history, admission period, total fever duration, fever duration after hospitalization, post-oseltamivir medication peak temperature, laboratory test, chest X-ray, antibiotic medication, and the presence of concomitant viral or bacterial infections. RESULTS: The number of subjects in our study was 72 who were diagnosed with influenza B pneumonia, acute bronchitis, acute bronchiolitis, croup, and mean age was 3.6+/-2.8 year old. The demographic characteristics and clinical manifestations of oseltamivir and the non-oseltamivir groups, including hospitalization period (4.18+/-2.10 vs 4.79+/-1.49 days, P=.17) and total fever duration (5.32+/-2.07 vs 6.41+/-3.25 days, P=.09), demonstrated no significant differences. Notably, the oseltamivir group did have significantly reduced usage of antibiotic treatment than the non-oseltamivir group (P=.04). When we limited our patient group to patients under the age of three, similar results were seen. The group prescribed oseltamivir within 48 hours of fever onset had less antibiotic usage, in addition to a shorter fever duration. CONCLUSION: Oseltamivir appeared to have no benefit in improving the clinical course. However, if it is prescribed within the first 48 hours of symptoms, it may be more effective.

BACKGROUND: Autoimmune hemolytic anemias are characterized by autoantibodies recognizing antigens on the Individual's own red blood cells, resulting in immune- mediated hemolysis. Blood transfusions have been regarded as hazardous in patients with autoimmune hemolytic anemia (AIHA) because of potential intensification of hemolysis and a presumed high incidence of alloimmunization. METHODS: We examined the pretransfusion and posttransfusion hemoglobin levels in 6 patients with autoantibodies in their sera, which showed panagglutinations with all bloods tested in the compatibility testing. They received 'least' incompatible blood because of inability to find compatible blood. RESULTS: When we compared pretransfusion hemoglobin level with posttransfusion hemoglobin level, in 5 of 6 patients with AIHA, the hemoglobin levels were increased after red cell transfusion. 4 patient who did not respond to transfusion therapy initially had an increase in hemoglobin level after steroid treatment. Any signs or symptoms indicating hemolytic transfusion reaction were not observed ducting the transfusion period in all patients. CONCLUSIONS: The decision to transfuse in AIHA should consider multiple factors including the patient's clinical status, the potential benefit of transfusion, the potential response to other therapeutic modalities, but must never be regarded as contraindicated, even though the compatibility test may be strongly incompatible.

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.
