In recent years, the incidence of proximal femur fractures has been increasing with the aging of the population. There has been a growing number of those patients who injure on the other side of the hip at later date. We studied the relationship between proximal femurfractures and knee osteoarthritis, which is one of the diseases preceding fractures.
We surveyed 234 and 17 patients hospitalized with unilateral and bilateral fractures, respectively at Atsumi Hoapital from April 2008 to March 2011. The research covered sex, age, the cause of injury, the period until they had proximal femur fractures on the other side, bilateral-fracture rate, incidence rates of diseases (cerebrovascular, eye and respiratory), knee osteoarthritis, dementia, diabetes and other forms of fracture.
As a result, we confirmed the connection between knee osteoarthritis and bilateral fractures. There was every indication that knee osteoarthritis may be a major factor which leads to bilateral fractures. All patients with bilateral fracture injured resulting from falls.
We believe it is important to take an approach on the treatment of hip fractures and prevention of knee osteoarthritis and falling.

Inflammatory bowel disease (IBD) is an idiopathic, multi-etiological disease characterized by inflammation and mucosal destruction of the gastrointestinal tract. Despite the remarkable advance in immunomodulating therapies, there still remains a certain population of patients who are refractory to conventional as well as biologic therapies and fail to achieve mucosal healing. To improve the prognosis of those patients, at least 2 types of stem cells have been tested for their potential therapeutic use. Transplantation of hematopoietic stem cells or mesenchymal stem cells have been tested in several clinical studies, but their beneficial effect still remains controversial. In this review, we would like to overview the recent clinical challenges of stem cell-based therapies in IBD and also introduce our new therapeutic plan of intestinal stem cell transplantation for IBD, based on our ex vivo intestinal organoid culture technique.

We began gastric mass survey at our hospital in May, 1980. During 3 years and 8 months since then, (May, 1980-December, 1983) we performed screening examinations to 16, 341 people by indirect radiography, and checked 2, 824 cases (17.3%) for thorough examination. Among these cases, 2, 083 (73.8%) received endoscopic examination actually, and 55 cases of gastric cancer were discovered. The discovery rate of gastric cancer was 0.336 per cent.
35 cases of these 55 gastric cancer were operated in the surgical department of our hospital. 34 cases were resected (rate of resection was 97.1%) and 33 cases were resected curatively (rate of curative resection was 94.3%). These results were better than that of gastric cancer cases from out-patient clinic of the same period. The results of cases from out-patient clinic of our hospital were: total number of cases 321, resected cases 254 (79.1%), curative resection 189 cases (58.9%), respectively.

Farmer's lung is a form of hypersensitivity pneumonitis, which is manifested mainly as an occupational disease among dairy farmers exposed to organic dusts from moldy hay and compost in silos and lofts. In Europe and America, it has been known for many years. In Japan, it frequently occurs in Hokkaido, Iwate and Hokuriku districts during winter months from November to March. The culprit antigens are spores of actinomycetes thermophilus such as Micropolyspora faeni and Thermoactinomyces vulgaris. In recent years, various preventive measures have been taken. For instance, in order to prevent hay from heating by fermentation and the thermophile from thriving, farmers desiccate hay as much as possible and keep it in air-tight plastic containers. The result is a notable decrease in the prevalence rate of this ailment. Nonetheless, with graying the rural population, pulmonary fibrosis caused by chronic exposure to low levels of organic dust is posing a grave health problem in the dairy farming communities. As a prophylactic measure against chronic fibrotic lung disease, there is a need to implement a comprehensive heath control program consisting of continual sanitary checkups at workplace and counseling at an early stage in addition to periodic health examinations. Another health threat which has more recently loomed up in the dairy farming communities is environmental pollution.

Based on two years working of “the enlarged working group for the curriculum of chemistry for medical education”, a provisional plan of the curriculum of chemistry for medical students is proposed. The article is consist of four sections; namely A: general problems, B: “chemistry” as a general education, C: purpose and specific problems of the general education for medical students, D: a provisional plan of the curriculum of chemistry for medical students.
The main part D is consist of three subsections: namely (1) a plan of the curriculum of physical and inorganic chemistry, (2) a plan of the curriculum of organic chemistry, (3) a plan of the curriculum of experiments.

Since hand deformities in rheumatoid arthritis (RA) are relatively not very painful, the worsening of the deformities often goes unnoticed and the functional impairment progresses irreversibly. Herein, we report a case of boutonnière deformity of the left middle and ring fingers treated with rehabilitation since an early stage. The patient was a 58-year-old woman who was referred to our hospital due to joint pain in the fingers and feet, following which a diagnosis of RA as made;however, she could not be administered methotrexate due to complications. PIP joint deformity of the left middle and ring fingers developed later. The middle finger was in -50-degree extension and difficult to correct passively, while the ring finger was in -35-degree extension and correctable. Surgery for the left middle finger was proposed based on the diagnosis of boutonnière deformity;however, consent was not obtained. After a steroid injection in the painful middle finger, she was managed using a Capener splint and ROM exercises with finger stretching. The symptoms improved five months following the rehabilitation intervention. Nalebuff et al. classified the severity of the boutonnière deformity based on the limited PIP joint extension and recommended treatment accordingly. In this case, surgical treatment was believed to be required;however, since the patient refused surgery, conservative treatment was chosen. Although the extension was severe, there was little joint destruction, due to which the symptoms improved with early and active intervention. Orthotic treatment and occupational therapy were effective in improving ADL.

A 68-year-old man was admitted to our hospital with complaints of fatigue, polyuria, and loss of appetite, and was diagnosed with diabetic ketosis. Chest and abdominal computed tomography (CT) showed a pulmonary tumor on the right S3 and multiple liver tumors. Blood chemistry revealed elevated levels of amylase and hepatobiliary enzymes. Pathological examination of a biopsy specimen from the liver tumor showed a small cell carcinoma. Based on the imaging and pathological findings, we made a diagnosis of extensive disease small-cell lung cancer (ED-SCLC), cT1aN3M1b (HEP, ADR). Treatment with carboplatin and etoposide evoked partial response and the serum level of amylase decreased. Immunohistochemical staining of liver biopsy specimen was positive for amylase, leading to a diagnosis of SCLC with amylase production. About 22 months after the diagnosis of SCLC, he was admitted to our hospital with fatigue, muscular weakness, edema, and hyperpigmentation. Laboratory findings showed elevated serum levels of hepatobiliary enzymes, adrenocorticotropic hormone (ACTH), and cortisol, and a decreased serum potassium level. Urinary potassium level was elevated. Pituitary magnetic resonance imaging showed a normal morphology. We made a diagnosis of SCLC complicated by Cushing’s syndrome. We report this rare case of SCLC with amylase and ACTH production, which was detected in the course of treatment of SCLC.
