Little has been written about reconstructive methods after resection of melanomas in the head and neck region. We investigated reconstructive methods retrospectively related to the site and size of the melanomas resected by examining the medical records of 28 patients who had malignant melanomas of the head and neck resected at our hospital from 1984 to 2001. The tumour distribution was 12 in the cheek, 6 in the conjunctiva, 2 in the upper lip, 2 in the lower lip, one each in the lower eyelid, eyebrow, scalp, nose, and auricle. Reconstructive methods were 18 skin grafts, seven local flaps, and three free flaps. Three patients who had skin grafts required secondary reconstruction using free flaps. No local recurrences were observed. Reconstructions with local flaps give better aesthetical and functional results than free flaps and skin grafts. Immediate reconstruction with a flap is safe and it does not affect observation of local recurrences. 相似文献

We investigated control and coding region polymorphisms in mitochondrial DNA (mtDNA) in 100 unrelated individuals from a Japanese
population and determined the basal phylogenetic haplogroup lineages in all samples under updated information. Many of the
basal phylogenetic haplogroup lineages assigned on East Asian mtDNA haplogroups corresponded to those previously established.
However, new haplogroup lineages such as M7a2a, M7a2b, M7a2*, M7c1b, M11b2*, G2b*, D4c1b1a, D4g2b, A4*, A9, N9b*, B4d1, B4d2,
and F1e were identified and established by complete sequencing. Although sequence comparison of the 1.15-kb control region
identified 84 mitochondrial haplotypes, examination of coding region polymorphisms increased the total number of haplotypes
to 91. Determination of the basal haplogroup lineages increased the discrimination power of mtDNA polymorphisms for personal
identification and their usefulness in determining geographic origin in forensic casework in Japanese and other East Asian
populations. 相似文献

The recurrence rate of GDM among women in Japan who had GDM or one abnormal value on 75 g oral glucose tolerance test (OAV) during an initial pregnancy is unclear. We therefore sought to determine the recurrence rate and risk factors of recurrent GDM by evaluating 32 patients with GDM and 37 with OAV in their index pregnancies. Medical records and chemical data were compared between patients with and without GDM in their subsequent pregnancies. The recurrence rate from index GDM and OAV were 65.6% and 40.5%. Age, BMI before pregnancy, an increased weight gain between pregnancies and a short interval between pregnancies were risk factors for recurrence from the initial GDM. An increased weight gain between pregnancies and a short interval between pregnancies were risk factors of development to GDM from the initial OAV. We concluded that the control of weight gain and interval between pregnancies could be important to reduce GDM recurrence. 相似文献

An unknown skeletonized body was identified by DNA analysis and dental information. The body had already been cremated when a candidate for the unknown body was proposed. Therefore, for DNA analysis we used teeth that had been kept for a long time after use for serological examination. We also used a chest X-ray photograph of the candidate and photographs of dentition, as well as dental X-ray photographs taken when the unknown body was found. Because DNA obtained from teeth was highly degraded, we amplified three PCR fragments to determine the 766 bp mitochondrial DNA (mtDNA) sequence including HV1 and HV2. Polymorphism of the ABO locus was also analyzed using small PCR fragments. Although the isolated DNA was contaminated, probably with DNA from a different individual, DNA polymorphisms of mtDNA and the ABO locus could be analyzed. We discuss the reliability of our conclusions from the point of view of the necessity of constructing an accurate mtDNA database. Although a dentist who had treated the teeth of the unknown body could not be found, a chest X-ray photograph for medical diagnosis was very useful in comparing dental characteristics, as it included an image of the frontal part of the lower jaw and upper teeth. 相似文献

Ten patients underwent reconstruction of skull base defects between 1989 and 1992. In this series, the maximum size of the skull base defect was 6 × 5 cm. Three patients underwent bone grafts to reinforce the skull base. The postoperative course of seven patients without bone grafts was uneventful. There was no cerebrospinal fluid leakage, meningitis, extradural abscess, on brain herniation. On the other hand, two of the three patients with bone grafts developed extradural abseesses requiring the bone grafts to be removed. Although the number of patients in this series is not large, this study demonstrates that the use of bone grafts in reconstruction of skull base detects could be one of the factors in increasing the chances of infectious complications. We think that a bone graft is not necessary to reconstruct moderate-sized skull base defects. 相似文献

Accumulation of fat in the liver is associated with insulin resistance and type 2 diabetes mellitus. The carnitine palmitoyltransferase (CPT) enzyme system facilitates the transport of long-chain fatty acids into mitochondria, and the gene for the hepatic isoform of CPT1 (CPT1A) is a candidate gene for metabolic disorders such as insulin resistance associated with fatty liver. We have now investigated the contribution of the CPT1A locus to hepatic lipid content (HLC), insulin resistance, and susceptibility to type 2 diabetes mellitus. A total of 324 type 2 diabetic patients and 300 nondiabetic individuals were enrolled in the study. Eighty-seven of the type 2 diabetic patients who had not been treated with insulin or lipid-lowering drugs were evaluated by homeostasis model assessment for insulin resistance and were subjected to nuclear magnetic resonance for determination of HLC. A total of 19 single nucleotide polymorphisms (SNPs) were identified at the CPT1A locus, and linkage disequilibrium analysis revealed a strong linkage disequilibrium block between SNP8 (intron 5) and SNP17 (intron 14). Neither haplotypes nor SNPs of CPT1A were found to be associated either with susceptibility to type 2 diabetes mellitus or with HLC or insulin resistance in type 2 diabetic patients. 相似文献

Bartter's syndrome is a rare renal disorder, and since there are few case reports of Bartter's syndrome complicating pregnancy are few, the changes of electrolytes and hormonal metabolism during pregnancy are unknown. We describe and discuss the course of pregnancy complicated with Bartter's syndrome. 相似文献
