Vitamin D (VD) exerts a wide variety of biological actions in addition to its well-known roles in calcium homeostasis. Nutritional VD deficiency induces rachitic abnormalities in growing children and osteomalacia in adults, and it has been proposed to underlie the onset and development of multiple non-communicable chronic diseases. Therefore, the administration of VD or synthetic VD analogues represents a promising therapeutic strategy; indeed, VD and a VD agonist have shown clinical promise in mitigating osteoporosis and symptoms of insufficient calcium intake. However, even though high doses of VD analogues have shown pre-clinical efficacy against several diseases, including cancers, they have not yet had wide-spread clinical success. This difference may be due to limitation of clinical doses in light of the inherent calcemic action of VD. An approach to overcome this problem involves the development of VD analogues with lower calcemic activity, which could be administered in high doses to attenuate the onset and progress of disease. In a similar strategy, selective estrogen receptor modulators have had success as anti-osteoporosis drugs, and they have shown benefit for other estrogen target organs by serving as partial antagonists or agonists of estrogen receptor α. It is thus conceivable to generate synthetic partial antagonists or agonists for the VD receptor (VDR) that would exert beneficial effects on bone and other VD target organs. In this review, we discuss the molecular basis of the development of such synthetic VDR ligands from the viewpoint of roles of VDR in gene regulation.

Objective: To apply the International Federation of Gynecology and Obstetrics (FIGO) 2018 staging system to all patients who underwent trachelectomy in our previous study and to update the oncologic and obstetric results. Methods: We retrospectively reviewed the medical records of patients in whom abdominal trachelectomy was attempted between June 2005 and September 2021. The FIGO 2018 staging system for cervical cancer was applied to all patients. Results: Abdominal trachelectomy was attempted for 265 patients. Trachelectomy was converted to hysterectomy in 35 patients, and trachelectomy was completed successfully in 230 (conversion rate: 13%). Applying the FIGO 2018 staging system, 40% of the patients who underwent radical trachelectomy had stage IA tumors. Among 71 patients who had tumors measuring ≥2 cm, 8 patients were classified as stage IA1 and 14 as stage IA2. Overall recurrence and mortality rates were 2.2% and 1.3%, respectively. One hundred twelve patients attempted to conceive after trachelectomy; 69 pregnancies were achieved in 46 patients (pregnancy rate: 41%). Twenty-three pregnancies ended in first-trimester miscarriage, and 41 infants were delivered between gestational weeks 23 and 37; 16 were deliveries at term (39%) and 25 were premature deliveries (61%). Conclusion This study suggested that patients judged to be ineligible for trachelectomy and patients receiving overtreatment will continue to appear using the current standard eligibility criteria. With the revisions to the FIGO 2018 staging system, the preoperative eligibility criteria for trachelectomy, which were based on the FIGO 2009 staging system and tumor size, should be changed.

Patients with Parkinson's disease (PD) experience difficulties with activities of daily living (ADLs) at workplace and in their social life depending on the extent of disease progression. Because of their disabilities, patients with PD are forced into early retirement compared to other people of their age group. We present our experience with the rehabilitation of three patients with PD using levodopa-carbidopa intestinal gel (LCIG) treatment for their return to work. The rehabilitation program comprised the following three modules：1) evaluating the patients' ability to walk indoor for a short time；2) assessing their standing and sitting positions to enable them to more easily handle a device；and 3) improving their upper limb function, including skilled movements, for operating a device in emergency. Finally, all three patients exhibited improvements in the Timed Up and Go test results and device operation. Two of the patients returned to their former workplace within 10 months of LCIG treatment initiation and the remaining patient found new employment 1 year after treatment commencement.In conclusion, establishing a rational support system that involves rehabilitation programs and information sharing across multiple occupations is essential for the return to work of patients with PD receiving LCIG treatment.

Previous studies have demonstrated that Java ginger ( Zingiber purpureum) that is called ‘Bangle’ in Indonesia have some kinds of cognitive effects. In order to evaluate the safety of Java ginger bangle, we studied the genotoxicity by micronucleus test. The result shows that Java ginger bangle have no effect inducing appearance of micronucleus.

In the palliative setting, the necessity of biliary drainage of both liver lobes for malignant hilar biliary obstruction remains controversial. However, bilateral biliary drainage is a reasonable option to prevent cholangitis of the undrained lobe and to preserve liver function during the course of chemotherapy. Bilateral biliary drainage can be accomplished by the percutaneous or endoscopic placement of multiple self-expandable metallic stents (SEMS). Although SEMS placement via bilateral (multiple) percutaneous routes is technically simple, multiple percutaneous transhepatic biliary drainage (PTBD) may lead to additional morbidity. SEMS placement via a single percutaneous route is a useful method; however, negotiation of a guidewire into the contralateral bile duct is occasionally impossible if the hilar angle between the right hepatic duct and left hepatic duct is acute. Percutaneous dual SEMS placement is generally performed using the stent-in-stent technique (T configuration or Y configuration) or the side-by-side technique. In addition, the crisscross technique has been reported as being a useful method for trisegmental drainage. The side-to-end technique is also useful for multiple SEMS placement. In the future, the combination of percutaneous intervention and endoscopic ultrasonography-guided procedures may be effective in the management of malignant hilar biliary obstruction.

Chronic expanding haematoma (CEH) is a rare type of haematoma that enlarges slowly and continuously without coagulation. It can occur following surgery because of shear stress-induced bleeding in the scar tissue between the subcutaneous fat and fascia. We present three cases of large chronic CEH that were successfully treated with triamcinolone injections. Three female patients developed large chronic CEH at 9 months, 5 years, and 6 years, respectively, after latissimus dorsi flap harvesting for breast reconstruction. Although the condition did not improve after multiple sessions of haematoma aspiration in the first two patients, it resolved following a single 40-mg triamcinolone injection along with appropriate compression dressing for several weeks. In the third patient, triamcinolone was injected immediately after the initial aspiration of the haematoma, and the condition improved considerably. There were no side effects in any of the patients. To the best of our knowledge, this is the first report of successful treatment of large CEH using triamcinolone. Therefore, we suggest that triamcinolone injections be considered for the treatment of CEH.

A 62-year-old woman was admitted to our hospital because of dextrocardia on her chest X-ray film. She had been in good health though the X-ray abnormality had been pointed out from her childhood. Echocardiogram, magnetic resonance imaging, and cardiac catheterization revealed situs inversus, congenitally corrected transposition of the great arteries, and severe tricuspid valve (systemic atrioventricular valve) regurgitation with mild systemic ventricular dysfunction. The surgeon stood on the patient's left side during the operation. On cardiopulmonary bypass, the tricuspid valve, facing almost dorsally, was exposed through a superior transseptal approach. Tricuspid valve replacement with a mechanical valve was performed with leaflet preservation. Systemic ventricular function is preserved at one year after operation.

Masked obesity is the presence of obesity based on percent body fat (%BF) when the body mass index (BMI) shows an absence of obesity. To examine the relationship between masked obesity and arteriosclerosis risk factors, we compared both serum lipid levels and the prevalence of hyperlipidemia in male and female high school freshmen with and without masked obesity. Subjects consisted of 403 male and 326 female high school students aged 15∼16 years. Of these, 34(8.4%) males and 36(11.0%) females had masked obesity, defined as 17≤BMI<23.60 and %BF≥25% in males, and 17≤BMI<24.17 and %BF≥30% in females, while the remaining 300 males and 246 females were not obese, having 17≤BMI<23.60 and %BF<25% and 17≤BMI<24.17 and %BF<30%, respectively. For both sexes, serum total-cholesterol (TC), low-density lipoprotein cholesterol (LDLC), triglycerides and the arteriosclerotic index (AI) were significantly higher (p<0.05∼0.01) in those with masked obesity. And many of the subjects with masked obesity had abnormal levels of TC, LDLC and AI, compared with those who were not obese (p<0.05∼0.01). Additionally, we compared both serum lipid levels and the prevalence of hyperlipidemia between subjects with masked obesity and control groups with the same BMI values. As a result, subjects with masked obesity had high serum lipid levels and a prevalence of hyperlipidemia. These results support the existence of masked obesity and suggest that masked obesity is associated with increased serum lipid levels, and thus could be a risk factor for arteriosclerosis in male and female high school freshmen.

The purpose of this study was to investigate the effects of short-term living and training at an altitude of 1, 300 to 1, 800 m on physiological responses of high school elite endurance athletes. Fifteen male and seven female senior high school elite athletes, aged from 15 to 18, from three different sports (cross-country skiing, long-distance running and endurance cycling), participated in our study. The short-term (6 days) altitude exposure did not elicit abnormal responses of body tempera-ture, body weight, blood pressure or urine samples. There were also no significant changes in blood parameters examined before and after altitude exposure. Resting heart rate (HR) increased at altitude and presented an initial peak value followed by a steady decline on the following days of altitude exposure. Blood lactate concentration and exercise peak llR examined by submaximal 20-m shuttle run test decreased after the ascent to altitude and still showed lower values at postaltitude than at prealtitude. We conclude that 6-day living and training at an altitude of 1, 300 to 1, 800 m elicits positive decrements of exercise blood lactate and exercise peak HR as well as adaptive changes of resting IlR for these high school elite endurance athletes, which are probably related to an attenuation of muscle glycogen utilization and alterations in the autonomic neural system taken at altitude.
