The authors report the advantages of the groin osteoadiposal flap for facial augmentation, which include the possibility of a conjoint type of flap harvesting with one main set of vessels (usually, the superficial circumflex iliac vessels); one-stage augmentation without secondary defatting; a donor scar in a concealed area; and rigid flap fixation with bone plating.
A case of a 40-year-old female with meralgia paresthetica after malignant tumor resection in the right inguinal region is reported. Traditionally, meralgia paresthetica is treated with neurotransection or neurolysis. The therapeutic strategy using neurolysis, and the use of a deep inferior epigastric perforator adiposal flap wrapping as a prophylactic procedure against reentrapment is discussed.
The authors present two cases in which the venous drainage of transferred flaps was compromised and the flaps were salvaged by vein grafts. Traditionally, once transferred free flaps had become congestive, surgeons would re-anastomose the thrombosed veins, and administer anticoagulants or carry out peripheral vessel dilation. These authors recommend not only re-anastomosis of veins, but also additional venous drainage, with or without vein grafts.
Platelet-activating factor (PAF), which has been implicated in the pathophysiology of inflammation in asthma, is degraded and inactivated by PAF acetylhydrolase (PAFAH). Approximately 4% of the Japanese population lacks plasma PAFAH due to a loss-of-function variant (Val279Phe) in the PAFAH gene. Although lack of PAFAH activity is thought to be a risk factor for asthma, there are conflicting findings concerning association between the Val279Phe variant and asthma. In this study, we conducted transmission disequilibrium tests of 118 Japanese parent-child trios identified through mite-sensitive atopic asthmatic children. A case-control study was also carried out. The Phe279/Phe279 genotype was found more frequently in children with atopic asthma (13%) than in their parents (6%) or in controls (4%). Results of the genotypic transmission test were significant, and the Phe279/Phe279 genotype was transmitted preferentially to asthmatic children. Our data support an association between deficiency in PAFAH activity and atopic asthma.
BACKGROUND: In elderly patients with diabetic nephropathy, clinical information aiming at preventing a decline of the renal function is limited. OBJECTIVE: To clarify factors that could be related to changes in renal function in elderly diabetic patients with persistent albuminuria. METHODS: We studied the relationships between the declining rate of creatinine clearance (Ccr) and other clinical features - glycemic control, blood pressure (BP), the degree of albuminuria, and other confounding factors - retrospectively in elderly diabetic patients with persistent albuminuria. RESULTS: We analyzed 17 elderly diabetic patients with persistent albuminuria (4 men and 13 women, mean age 68.0 +/- 5.7 years at the beginning of the observation period) for 3.7 +/- 1.5 (SD) years. We found that the last value of the urinary albumin excretion (UAE) of the observation period and the individual mean values of systolic BP, mean BP, and serum cholesterol closely correlated with the rate of decline in Ccr estimated by Cockcroft's formula. The last UAE closely correlated with the individual mean values of systolic BP and mean BP. For patients such as the present subjects, adequate retardation of decline in renal function requires that the estimated goal of antihypertensive treatment should be a BP below 130/70 mm Hg. The level of glycemic control and the use of angiotensin-converting enzyme inhibitors did not correlate with the rate of decline in Ccr. CONCLUSION: Aggressive antihypertensive treatment and serum lipid lowering therapy may be necessary to prevent deterioration of the renal function in elderly type 2 diabetic patients with persistent albuminuria.
