Successful kidney transplantation usually resolves secondary hyperparathyroidism (SHPT). However, some patients fail to normalize, and their condition is often referred to as tertiary hyperparathyroidism (THPT). Surgical consensus on the timing of post-transplant parathyroidectomy (PTX) for THPT has not been reached.

Preoperative laboratory examination revealed the syndrome of inappropriate secretion of TSH, however, the patient had no thyrotoxic symptoms and no family history. Based on the results of ultrasonography and fine needle aspiration, she was diagnosed with papillary thyroid carcinoma and underwent total thyroidectomy.

A 60-year-old man underwent left upper lobe partial resection for small size lung adenocarcinoma under video assisted thoracic surgery (VATS).

She was treated with 2 courses of 70 mg docetaxel (DOC) chemotherapy every 3 weeks, after which the tumor dramatically decreased in size.

In July 2005, a 49-year-old woman was admitted because of delirium, transient loss of consciousness, and a giant mass of about 28 cm in diameter on the right breast. She had noticed the mass for more than 2 years, but had refused medical attention at that time.

Histological examination of this nodule showed metastatic carcinoma from breast cancer. Further examination revealed paraaortic lymph node swelling and no breast tumors.

Our previous studies revealed a variety of genetic changes in lung cancers from chromate-exposed workers (chromate lung cancer). However, the epigenetic effects of chromium are not understood.

AIM/PATIENTS AND METHODS: We investigated the involvement of the HRPT2, MEN1 and CASR genes in 11 provisional FIHP families and two HPT-JT families.
Results: Germline mutations of HRPT2 were found in two of the 11 FIHP families and one of the two HPT-JT families.

We report an adult case of accessory cardiac bronchus (ACB) which extended from the carina to the diaphragm. A 32-year-old woman, with a history of frequent respiratory infections since childhood, recently presented with bloody sputum, and was admitted to our hospital. The ACB was detected as a supernumerary bronchus diverging from tracheal bifurcation.

Recently, many clinical studies have demonstrated that UFT is effective for cancer with a low activity of thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD). In the present study, we investigated TS and DPD activity in resected tumors and corresponding normal lungs and the relationship between the activity and the mRNA expression of TS and DPD in NSCLC.
View Article and Find Full Text PDFOur previous studies of lung cancer in chromate-exposed workers (chromate lung cancer) have revealed that the frequency of replication error (RER) in chromate lung cancer is very high. We examined whether the RER phenotype of chromate lung cancer is due to an abnormality of DNA mismatch repair protein. We investigated the expression of a DNA mismatch repair gene, hMLH1, and hMSH2 proteins using immunohistochemistry and microsatellite instability (MSI) in 35 chromate lung cancers and 26 nonchromate lung cancers.

Methods: We reclassified a series of 100 thymomas resected at Tokushima University Hospital and four affiliated hospitals in Japan between 1973 and 2001 according to the World Health Organization histologic classification and reported its clinicopathologic relationship and prognostic relevance.
Background: It is known that chromium is an inhaled carcinogen and an important risk factor in the development of lung carcinoma.
Methods: The authors used a microscopic X-ray fluorescence analyzer with transmitted X-ray mapping imaging (Horiba, Kyoto, Japan) to measure the accumulation of chromium in 10 resected lung tissue specimens and 90 biopsy specimens from chromate workers.
Results: The maximum chromium accumulation (mean +/- standard deviation) in 10 resected lung tissue specimens was 197 +/- 238 counts per second (cps)/mili ampere (mA) (range, 4-649 cps/mA).
Although chromium has been the most extensively investigated metal with respect to mutagenicity and carcinogenicity, its genetic effects in humans are only partly understood. Our previous study demonstrated that lung cancer from chromate-exposed workers infrequently (20%) displayed p53 gene mutations as well as a particular mutation pattern. In the present study, we examined the replication error (RER) and loss of heterozygosity (LOH) in 38 lung cancers from 28 chromate-exposed workers (chromate lung cancer group) and in 26 lung cancer patients without chromate exposure (non-chromate lung cancer group), using six microsatellite markers containing CA repeats: D3S647 (3p23), D3S966 (3p21.
View Article and Find Full Text PDFA case of localized adiposity of the thyroid in a 35-year-old woman with a long history of steroid therapy for nephrotic syndrome is reported. A well-demarcated yellowish mass measuring 2 cm in diameter was found in the upper portion of the right lobe of the thyroid. Microscopically, this lesion was composed of mature adipose tissue partially mixed with thyroid tissue and had no distinct capsule.
