1.The External Auricular Reconstruction with Inferior Based Retroauricular Flap Including the Posterior Auricular Artery.
Archives of Reconstructive Microsurgery 2016;25(1):1-6
PURPOSE: The external ear is a common area of trauma on the body prone to exposure of ultraviolet light, which can lead to skin cancer. Thus, variable techniques have been developed and used for reconstruction of the external ear. The aim of this study is to review the surgical method, its area of application, as well as advantages and pitfalls of reconstruction of the external ear with inferior based retroauricular flaps. MATERIALS AND METHODS: Eight patients underwent external ear reconstruction with inferior based retroauricular flap for external ear defects in our institute from September 2012 to June 2015. According to the area of the defect, patients were classified as middle 1/3 (n=4), inferior 1/3 (n=2), superior auroculo-cephalic sulcus (n=1), and external auditory canal (n=1). RESULTS: All of the flaps survived the operation and there was no marginal necrosis. Mean size of the defect was 2.8×1.8 cm and mean size of the retroauricular flap was 5×2 cm. For insetting of the flap, a subcutaneous tunneling technique was used in 6 cases and rotation without subcutaneous tunneling was used in 2 cases. Transient paresthesia occurred in 3 cases. Two cases recovered within 3 months but one case did not recover until 6 months. CONCLUSION: The inferior based retroauricular flap is an available technique in external ear reconstruction with one stage operation.

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.

9.Cultured Epithelial Autografts (Sheet & Suspension Type).

Journal of Korean Burn Society 2009;12(1):12-15
The treatment application of cultured epithelial autograft (CEA) is the only selected treatment method when performing skin graft for treating massive burns over 70 to 80%. Clinically 2 types of CEA, sheet type and suspension type, are currently available in Korea. The sheet type of CEA, Holoderm(R), was commonly used since no other CEA were available. Since the recent introduction of the suspension type, Keraheal(R), the suspension type is also clinically used. Although 2 types are different in type of forms provided but both types are clinically effective for increasing survival rate of massive burn patients. The early treatment method of massive burn is selected based on the rage of burns using Warden or Parkland Formula. The escharectomy is performed within 3 to 7 days of burn then cadaver skin allograft is applied immediately. At this time, the full thickness skin biopsy in the size of 2x3 cm is obtained from non burned area such as axilla, inguinal or abdomen. Then the skin biopsy is sent to the labs. The length of culturing time is less than 3 weeks for Holoderm(R) and around 2 weeks for Keraheal(R). Holoderm(R) is provided as a sheet type. It is simply applied over 1:3~1:6 meshed skin autograft and fixed with staplers together with skin autograft. In the other hand, the suspension type of CEA, Keraheal(R), is provided in a glass vial and sprayed over 1:3~1:6 meshed skin autograft using Tissomat(R). The fibrin sealant is sprayed after application of Keraheal(R) as a fixation of suspension CEA sprayed. Extra wound care is necessary even after both types of CEA are successfully taken since CEA applied regions are much more fragile than those regions applied skin autograft only. The treatment methods of applying cadaver skin allograft and culture epithelial autograft (CEA) are the most advanced treatments available for increasing survival rate of massive burn patients. The sheet type and suspension type of CEA show difference in type of forms provided but they both show successful take rate that enhance the burn treatment. We suspect that both types of CEA still need ongoing efforts and researches to enhance their advantages and eliminate disadvantages to increase the efficacy that can promote wound healing process of massive burn patients.
