A delayed hemolytic transfusion reaction (DHTR) is the result of delayed anamnestic alloantibody response four to fourteen days after transfusion of apparently compatible blood. Most DHTRs are very mild and may not be recognized clinically. Some are manifested only by anemia. Only a few cases are severe enough to induce a massive hemolytic reaction followed by frank renal failure. Recently, we experienced a case of DHTR with acute renal failure (ARF) due to anti-E. A 21-year-old woman received compatible four units of packed red cells after right artificial total hip replacement arthroplasty due to juvenile rheumatoid arthritis. She had a history of transfusion 4 years ago. Fourteen days after the transfusion, she showed a fall in hematocrit, hemoglobinuria and a positive indirect antiglobulin test, and accompanied by ARF. Anti-E was identified in the patient's serum by antibody screening and identification test at that time. She recovered from ARF after hemodialysis with conservative management. However, eventually, she died due to disseminated intravascular coagulopathy.

BACKGROUND: Most patients with head and neck cancer successfully undergo oncologic resection followed by free or local flap reconstruction, depending on the tumor’s size and location. Despite effective curative resection and reconstruction, head and neck cancer patients still face a high risk of recurrence and the possibility of a second primary cancer. Moreover, surgeons hesitate to perform sequential reconstruction following curative resection for several reasons. Few large-scale studies on this subject are available. Therefore, we retrospectively evaluated the outcome of sequential head and neck reconstruction to determine the possible risks. METHODS: In total, 467 patients underwent head and neck reconstruction following cancer resection at our center from 2008 to 2017. Of these cases, we retrospectively reviewed the demographic and clinical features of 58 who had sequential head and neck reconstruction following resection of recurrent cancer. RESULTS: Our study included 43 males (74.1%) and 15 females (25.9%). The mean age at the initial operation was 55.4±15.3 years, while the mean age at the most recent operation was 59.0±14.3 years. The interval between the first and second operations was 49.2±62.4 months. Twelve patients (20.7%) underwent surgery on the tongue, and 12 (20.7%) had procedures on the oropharynx. Thirty-four patients (58.6%) received a sequential free flap reconstruction, and 24 patients (41.4%) were treated using locoregional flaps. No cases of flap failure occurred. CONCLUSIONS: Our findings suggest that patients who need additional operations with recurrent head and neck cancer could optimally benefit from sequential curative resections and reconstructions.

The authors report two cases of epidermoid cyst in the cerebellopontine angle which presented as trigeminal neuralgia. The tumors were surgically removed by suboccipital craniectomy. The cysts were densely adherent to multiple cranial nerves, including the trigeminal nerve, and the tumors occupied adjacent cisterns. After removal of the cystic content, it was sometimes difficult to differentiate the tumor capsule from the arachnoid membrane. In one patient, trigeminal neuralgia was resolved immediately after the operation, while for two weeks postoperatively, the other suffered severe headache and facial dysesthesia due to aseptic meningitis. To avoid surgical complications, it is resonable to leave a minute capsule attached to cranial nerves or blood vessels.

Sarcomatoid transitional cell carcinoma is a rare malignant epithelial neoplasm arising at the bladder, in which the tumor cells assume a spindle shape. This tumor accounts for approximately 0.3% of all bladder malignancies and has been reported in the renal pelvis and ureter. We encountered a case of histopathologically proven sarcomatoid transitional cell carcinoma of the left kidney in a 76-year-old male. Abdominal CT scans showed a large heterogeneous mass of solid and cystic components, with mural calcification and hematoma in the upper pole of the left kidney.

BACKGROUND: Medium-sized congenital melanocytic nevi (CMN) require surgical excision because of the risk of malignant transformation and aesthetic concerns. There are various possible reconstruction methods after excision, such as primary repair, skin graft, local flap, and composite graft. In this study, we used skin-fat composite grafts for reconstructing full-thickness skin defects and assessed the aesthetic outcomes. METHODS: Facial nevi excision plus skin-fat composite grafts were performed in 11 children (range, 3-16 years old). All grafts were harvested from the preauricular area on one or both sides; they included the epidermis, full-thickness dermis, and subcutaneous fat. All procedures were performed simultaneously. Standardized photographs were taken preoperatively and at a mean follow-up of 10.5 months. Viewing the photographs, four plastic surgeons rated the aesthetic outcomes of all patients using the following scale: 1, poor; 2, fair; 3, good; 4, very good; and 5, excellent. RESULTS: No patient was diagnosed with malignancy. There were no complications, such as graft loss, infection, or aesthetic problems that required surgical revision. All donor sites healed well and exhibited only minimal scarring. The aesthetic outcomes of skin-fat composite grafts were outstanding with a mean score of 4.2 +/- 0.4. Most patients and parents were highly satisfied with the results. CONCLUSIONS: Skin-fat composite grafts provide good color match, texture, and contour. They are more tolerable, especially in children, because the technique involves simpler procedures and shorter operation times than local flaps. They may be the ideal option for facial defects after excision of medium-sized melanocytic nevi.

Despite recent advances in the care of such patients, subarachnoid haemorrhage(SAH) due to ruptured intracerebral aneurysm continues to carry a high rate of morbidity and mortality. During the acute phase of SAH, various factors can aggravate a patients initial good neurological state, and every effort should thus be made to prevent such occurrences. Although not a major problem, seizure is a well known factor influencing the course of the disease. The authors studied 476 cases of SAH occurring during the preceding eight-year period and reported the incidence of seizure, the risk factors which evoke it, and the optimal time required to prevent it. The incidence was 11%, and 48% of seizures occurred within three days of SAH. The risk factors were Hunt-Hess grade at admission, degree of neurologic deficit, and the presence and timing of rebleeding. Regardless of initial grade, seizure led to a poorer outcome. We conclude that seizure in aneurysmal subarachnoid hemorrhage occurs during the early stage of the disease and aggravates the prognosis. The recognition of risk factors and early prevention of seizure are thus necessary.

PURPOSE: We aim to compare the erythropoietic effects of epoetin-alpha (EA, 4000 IU SC thrice a week) with those of darbepoetin-alpha (DA, 60ug IV weekly, conversion rate to EA=200:1). METHODS: Forty one stable hemodialysis patients were enrolled in this randomized crossover study. After a washout period of erythropoietin stimulating agents (ESA), the patients with hemoglobin (Hb) level of < or =11.0 g/dL were randomly assigned to DA or EA and we measured Hb and reticulocyte levels. When Hb reached >11.0 g/dL, we stopped ESA. When Hb level decreased to < or =11.0 g/dL again, we switched to alternative ESA and repeated the rest of the steps. RESULTS: Thirty six patients (M:F=20:16, age 62+/-11 years, Kt/V 1.65, nPCR 1.13 g/kg/day) completed the study. No significant differences were observed in baseline parameters between DA and EA during the period of the clinical trial. The rate of Hb level increase (EA 0.29 g/dL/week, DA 0.30 g/dL/week, p=0.76) and decrease (EA 0.45 g/dL/week, DA 0.38 g/dL/week, p=0.14) were not different between two periods. After ESA stopped, the duration of decreased Hb level of < or =11.0 g/dL was not significantly different (4 weeks in EA vs. 3.9 weeks in DA, p=0.86). Erythropoietin resistance index was 10.59 in the EA period. It was not significantly different from 10.97 in DA period (p=0.49). Nine patients (25%) showed a >30% change in EA efficiency relative to DA efficiency. CONCLUSION: There was no significant difference in erythropoietic parameters for both EA and DA.

BACKGROUND: Minimal (subclinical) hepatic encephalopathy (mHE) currently diagnosed by psychometric tests or neurophysiological test adversely affects daily functioning. In view of its sociomedical relevance, simple and reproducible tests for routine diagnosis are required. The aims of this study are to evaluate cognitive function of patients with chronic liver disease by computerized neuropsychological test (STIM), and the difference of cognitive function according to Child classification. METHODS: Between June, 2002 and February, 2003 We enrolled 61 randomized consecutive patients diagnosed with chronic liver disease by biochemical tests, ultrasonographic finding or histology. This study used finger tapping, visual CPT, spatial memory test, Wisconsin card sorting test chosen from Neuscan and STIM system (Neurosoft company, U.S.A) and global-local processing test. RESULTS: In the present study, significant correlation was found between neurologic abnormalities and the degree of liver disease. The result of neuropsychological test showed that cognitive function was decreased according to the severity of chronic liver disease, especially liver cirrhosis. Cirrhotic patients, especially Child C group, exhibited selective deficits in complex attentional and fine motor skills, visuospatial perception, with preservation of memory. CONCLUSION: The STIM in this study is simple, objective and reproducible method because it can subdivide evaluation of cognitive function and computerize the measurement of response. We assume that STIM may be used early detection method of mHE if the study will be in a large scale. Because psychomotor deficits found in mHE could have a disadvanting influence on daily functioning of patients, e.g., driving abilty of a car or performance at work, we concluded early detection of mHE and aggressive treatment of mHE in clinically asymptomatic cirrhotic patients is necessary for improvement of their quality of life.

BACKGROUND: Malnutrition frequently occurs in patients with liver cirrhosis independently for its etiology and can modify prognosis of the disease. Since malnutrition was observed at all clinical stages, but more frequently seen at advanced stages, early and detailed nutritional assessment in all patients with liver cirrhosis is important. The aims of this study are to define the nutritional status and the difference of nutritional index according to etiology and Child classification in patients with liver cirrhosis in Korea. METHODS: A total 138 cirrhotic patients (41 alcoholic cirrhosis, 97 virus-related cirrhosis) were studied. The diagnosis of cirrhosis was based on clinical, laboratory and ultrasonographic criteria and liver biopsy. The patients were divided into three groups according to the severity of their liver disease as assessed by the Child-Pugh classification. Nutritional parameter of protein (serum albumin, serum transferrin, total lymphocyte count) were measured. RESULTS: The patients with protein malnutrition are as follows: albumin 55, transferrin 68, total lymphocyte count 8. The frequency of moderate to severe protein malnutrition was high in alcoholic cirrhosis.: albumin (<2.9 g/dL) (26.8% vs 17.5%), transferrin (<180 mg/dL) (48.5% vs 24.8%), total lymphocyte count (<1200 number/L) (2.4% vs 2.0%). The mean value of nutritional index correlated with the degree of liver function impairment. (Child C showed the lowest value). CONCLUSION: In spite of limitation of nutritional index in this study, our study showed that severe protein-energy malnutrition was rare in Korea, and protein-energy malnutrition was not only more common in alcoholic cirrhosis but related to the severity of liver disease. Therefore, our data suggests that clinician should understand the importance of not imposing unnecessary restrictions and supplementation on protein intake for fear of imbalance of nutrition.
