Traditional Japanese food appears to be healthy but contains a small amount of milk products. Type 2 diabetes (T2DM) patients commonly reduce their energy intake to control their blood glucose levels. However, nutritional guidance for diabetes does not emphasize calcium (Ca) consumption. The aim of this study is to estimate the nutritional status of Ca and other nutrients, which affect bone and Ca metabolism, in T2DM patients. This observational study was conducted with Japanese T2DM patients (n = 96; M/F = 50/46; age: 61.6 ± 10.1 years). We estimated nutrient intake using a simple food frequency questionnaire. Median total energy intake was 1750 kcal/day (1440–1970). Their median daily intake of Ca, vitamin D, and vitamin K was 451 mg (336–560), 10.2 μg (8.5–12), and 206 μg (84–261), respectively. Only 17.7% of the study subjects were found to take more than 600 mg/day of Ca. Protein and salt intake was 78 (64–90) and 10.6 (9.3–12.2) g/day, respectively. Male subjects had more salt, less Ca and vitamin K than female. Daily Ca intake was positively associated with total energy, protein, and lipid intake but not with carbohydrates. Vitamin D intake correlated only with protein intake. The daily Ca intake of Japanese T2DM patients appears to be insufficient and could depend on protein and lipid intake. Additionally, these patients should have specific recommendations to ensure sufficient intake of Ca with protein and lipid during energy restriction.
Abstract Background : We report here on a third case of squamous cell carcinoma (SCC) of the renal pelvis extending to the inferior vena cava. Methods/Results : A 48‐year‐old man was diagnosed with an advanced left renal pelvic tumor on computed tomography. He had undergone extracorporeal shock wave lithotripsy for left staghorn calculi 10 years ago. An inferior vena cavagram showed tumor thrombus extending to the inferior vena cava. Percutaneous left renal biopsy revealed SCC. The patient received three courses of combination chemotherapy with cisplatin, bleomycin and etoposide. However, 1 month after the last course of chemotherapy, he died of cancer progress. Conclusion : This is the third case of SCC of the renal pelvis extending to the inferior vena cava in the world.
Interactions between CD40 and its ligand (CD40L) have important roles in T-cell-dependent activation of B cells, which may be related to the thyrotoxic activity of Graves' disease (GD). Soluble forms of CD40 ligand (sCD40L) are released from activated T cells and platelets, and several types of inflammatory cytokines are increased in patients with hyperthyroid GD. The aim of this study was to assess sCD40L and other cytokines as clinical indicators of disease activity or as possible markers of remission in GD.Serum levels of sCD40L, interleukin 18 (IL-18), tumor necrosis factor-alpha (TNFα), and TNFα receptors 1 and 2 (TNFR1 and TNFR2) were investigated in patients with active GD (GD-A), intractable GD (GD-IT), inactive GD (GD-IA), GD in remission (GD-R), and Hashimoto's thyroiditis (HT), and in control subjects (CON).Serum concentrations of sCD40L were higher in the GD-A and GD-IT groups than in the HT and CON groups. Similarly, serum concentrations of IL-18, which induces Th1 cytokines, such as interferon-γ, were higher in the GD-A and GD-IT groups than in all other groups. Serum levels of TNFR1 and TNFR2 were also significantly higher in the GD-A than in all other groups. The mean serum concentration of TNFα was higher in the GD-R compared with the GD-A and GD-IT groups, although the difference was not significant. Serum sCD40L concentrations in the GD-R group were lower than in the GD-A and GD-IT groups. Finally, the ratio of serum TNFα to sCD40L was higher in the GD-R group than in the GD-A and GD-IT groups. This is the first report that serum sCD40L is increased in active GD, and that the serum TNFα:sCD40L ratio is a marker for remission in GD.Our results suggest that not only thyrotoxicosis, but also the activity of the immunoreaction presenting as anti-thyrotropin receptor antibodies (TRAb) titer in GD, affects inflammatory cytokine serum profiles. Serum profiles of cytokines vary in patients with GD depending on disease activity. An elevated serum TNFα:sCD40L ratio indicates declining disease activity and reflects a shift from Th2 to Th1 dominance, suggesting that suppression of sCD40L or increased production of TNFα is required to initiate or maintain remission of GD.
Abstract Retroperitoneoscopic ureterolithotomy was successfully performed in two patients with impacted upper ureteral stone. The retroperitoneal space was extended using a balloon dissector and four ports were established into the retroperitoneal space according to Gaur's procedure (1993). The impacted ureteral stone was removed after the ureter was incised using a hook electrode. An indwelling splint or stent was placed in the ureter. The incised ureter was not sutured and an indwelling drain was placed in the retroperitoneal space. Urine leakage ceased within 3 days postoperatively. With regard to complications, the first patient developed wound infection caused by methicillin‐resistant Staphylococcus aureus and the second patient had abscess formation in the psoas muscle. Retroperitoneoscopic ureterolithotomy should be useful as an alternative treatment for impacted ureteral stones because it involves minimal postoperative pain.
A 62-year-old woman was hospitalized with complaints of right upper abdominal discomfort. Various imaging studies showed an extremely large suprarenal mass with solitary cystic formation. Partial adrenalectomy was successfully performed through the transperitoneal approach. The resected mass measured 12 x 10 x 10 cm and weighed 600 g. A pathological examination showed an Antoni-B predominant-type benign schwannoma containing a large volume of degenerative fluid. Our search of literature yielded few reports of solitary cystic schwannomas in the retroperitoneal cavity or throughout the body. This unusual cystic manifestation is thought to be a terminal stage of degeneration of a long-standing schwannoma.
