Objectives:
Diagnosis and treatment of osteoporosis are instrumental in obtaining good outcomes of hip surgery.Measuring bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) is the gold standard for diagnosing osteoporosis. However, due to limited access to DXA, there is a need for a screening tool to identify patients at a higher risk of osteoporosis. We analyzed the potential utility of the Osteoporosis Self-assessment Tool for Asians (OSTA) as a screening tool for osteoporosis.
Methods:
A total of 1378 female patients who underwent hip surgery at 8 institutions were analyzed. For each patient, the BMD of the proximal femoral region was measured by DXA (DXA-BMD), and the correlation with OSTA score (as a continuous variable) was assessed. Receiver operating characteristic (ROC) curve analysis was performed to assess the ability of OSTA score to predict osteoporosis. Lastly, the OSTA score was truncated to yield an integer (OSTA index) to clarify the percentage of patients with osteoporosis for each index.
Results:
DXA-BMD showed a strong correlation with OSTA (r = 0.683; P < 0.001). On ROC curve analysis, the optimal OSTA score cut-off value of − 5.4 was associated with 73.8% sensitivity and 80.9% specificity for diagnosis of osteoporosis (area under the curve: 0.842). A decrease in the OSTA index by 1 unit was associated with a 7.3% increase in the probability of osteoporosis.
Conclusions
OSTA is a potentially useful tool for screening osteoporosis in patients undergoing hip surgery. Our findings may help identify high-risk patients who require further investigation using DXA.

A 38-year-old man was admitted to our hospital with fever and skin rash, and he was diagnosed as having dermatomyositis. He was treated with anti-inflammatory steroid and immunosuppressive agents. On hospital day 48, chest computed tomography (CT) revealed a nodule measuring approximately 2 cm in size in the lower lobe of the right lung (S9). Bacterial and/or fungal infection was suspected, but there was no response to antibiotic or antifungal treatment. A week later, repeat chest CT revealed the tumor now measuring approximately 6 cm in size in the lower lobe of the right lung. We performed bronchoscopy, and bacteriological examination of the transbronchial biopsy specimen revealed pulmonary tuberculosis. Interferongamma release assay (IGRA) before the initiation of immunosuppressive treatment was negative, so we did not administer treatment for latent tuberculosis infection. He was, however, treated with isoniazid, rifampicin, ethambutol, and pyrazinamide for 9 months, following which radiological features improved gradually. Here we describe in detail this rare case of a negative IGRA result before immunosuppressive therapy in a relatively young Japanese man who went on to develop active tuberculosis with a rapidly-growing pulmonary lesion during hospitalization.

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.

In patients with epidermal growth factor receptor (EGFR) mutation-positive lung cancer (LC) who have acquired resistance to first and/or second-generation EGFR-tyrosine kinase inhibitors (EGFR-TKIs), detection of EGFR T790M (T790M) mutation is essential before administration of osimertinib. Tissue sample is the main specimen used to detect the T790M mutation, and so cell block preparation using pleural or pericardial fluid should be considered. The utility of body cavity effusion cell block methods in T790M mutation detection have not yet been fully evaluated. This study aimed to evaluate the clinical background and treatment course of LC patients harboring the T790M mutation by using body cavity effusion cell block methods at our hospital. All patients were treated with first and/or second-generation EGFR-TKIs and had developed malignant pleural or pericardial fluid as a result of progressive disease. T790M mutation status was evaluated using body cavity effusion cell block method in 9 patients, from April 2016 to August 2017. We retrospectively evaluated the clinical characteristics and treatment course of these 9 patients (3 males and 6 females; median age 76 years). At the first diagnosis of LC, 7 patients had stage IV cancer; 4 patients were diagnosed by bronchial fibroscopy and 3 were diagnosed from pleural fluid examination. Regarding EGFR mutation, 3 and 6 patients carried the exon 19 deletion and L858R mutation, respectively. Median time interval between the first diagnosis of LC and T790M mutation evaluation was 30.8 months; 7 patients were diagnosed with positive T790M mutation by using body cavity effusion cell block methods. The T790M mutation was highly detected by examination of body cavity effusion cell blocks. Further evaluation is necessary with respect to variations in T790M detection rate based on the specimen collection site and/or progressive disease pattern in different patients.

A 56-year-old woman was referred to our hospital because of an abnormal finding in the right pulmonary hilum on chest X-ray. Enhanced chest computed tomography showed hyperplastic bronchial arteries dilating and winding around the trachea and bronchi. A racemose hemangioma of the bronchial artery with multiple bronchial artery aneurysms (diameter <20mm) was seen displacing the trachea and both main bronchi. Bronchoscopy showed submucosal tumor-like lesions at the distal trachea and in both main bronchi, and a dusky-red elevated pulsatile lesion at the orifice of the left B3b+c. We performed coil embolization of the bronchial artery aneurysm to prevent abrupt rupture of the bronchial aneurysm.

An 81-year-old man was referred to our hospital with bilateral multiple patchy opacities on chest radiography. His chief complaints were a few months’ history of intermittent mild cough and slightly yellow sputum. Chest computed tomography (CT) showed non-segmental air-space consolidations with ground-glass opacities. Amyloid deposition with organizing pneumonia (OP) was seen in transbronchial lung biopsy (TBLB) specimens from the left S8. Three months later, the infiltration originally seen in the left lower lobe was remarkably diminished, and new infiltrations in the lingual and right lower lobes were detected on chest CT. Amyloid deposition with OP was seen in TBLB specimens from the left S4. Transthyretin was detected following immunohistochemical examination. The presence of wild-type transthyretin (ATTRwt) was proven using genetic analysis. The present report describes a rare case of ATTRwt amyloidosis associated with OP.

Evidence suggests that sports activity can induce site-specific changes in bone mineral content (BMC) in athletes. Therefore, the first purpose of this study was to create a standard value for BMC (SVBMC) that is independent of body size and physical exercise effect. The second purpose was to examine usefulness for the SVBMC. In creating the SVBMC, we recruited non-customer subjects who engaged in regular exercise but did not have site-specific changes to their bony structure. We studied 285 females (34.0±6.5 years) that were currently active, free from hormone treatment, and were not taking medication for any condition. Furthermore, all female subjects reported having a normal menstrual cycle. Bone area (BA), BMC and areal bone mineral density (aBMD) were measured by dual-energy X-ray absorption. Measurements of almost the complete skeleton, with the exception of the head, were taken (herein referred to as sub-total). This included scans of the entire spinal column, all 12 ribs, pelvis, full legs and arms. An allometry formula that relates BMC and BA was applied to determine the SVBMC. To exclude the effect of body size, calculations were determined using the perpendicular distance from the data of each individual to that determined by allometry regression. Finally, the mean and standard deviation of the distance were converted into T-scores. In examination of reliability for the SVBMC, we calculated the SVBMC for three customer females who engaged in regular exercise. We found a significantly positive relationship between SVBMC and weight/BMI. This correlation was weaker than the relationship between SVBMC and BMC, as expected, or the relationship between SVBMC and aBMD, with the exception of SVBMC in the pelvis. In conclusion, this study suggests that SVBMC is less affected by body size than by BMC or aBMD and the SVBMC was provided highly useful in case study.

This study was performed by the purpose of early detection of Hand-Foot Syndrome (HFS) in patients receiving capecitabine therapy. Ten patients receiving chemotherapy with capecitabine after resection of colon cancer were included in this study. Surgeons decided the reduction or suspension of capecitabine when adverse effects were found. Pharmacists instructed the patients of the way of intake and side effects. Nurses instructed the patients how to make skin care with brochure and DVD. We called to or made an interview to the patients once a week in the first eight weeks of administration by evaluating the symptoms of HFS. Finally, a questionnaire was taken to evaluate the degree patients’ satisfaction. All of the ten patients continued the skin care in the study. HFS above grade 2 appeared in three cases, and early decision of reduction or suspension of capecitabine was achieved as the result of support by telephone call or interview. Support by either telephone call or interview by nurses in the medical team of chemotherapy can contribute to the completion of chemotherapy by capecitabine by detecting the HFS in the early stage which leads to the early decision of reduction or suspension and by reduce the anxiety of the patients. We also suggest the necessity of the construction of individualized support system to the patients in the future.

Since the effect of the submaximal aerobic exercise on bone had been controversial, the aim of this study was to elucidate the effect of the bench step (BS), that seemed to deliver higher mechanical load on bone than any other aerobic exercises, on the total bone mineral content (BMC) and the bone metabolism of menopausal women. Sixteen menopausal women (65 ± 9 years old) as the exercise group (ExG) and 28 pre-menopausal women (43 ± 3 years old) as the control group (CG) were studied. ExG carried out BS training with the exercise intensity at lactate threshold (LT) for 21 weeks. In ExG, BMC was measured by dual energy X-ray absorptiometry (DXA) at one year before the intervention (A year before), pre-intervention (Pre) and post-intervention (Post). Serum osteocalcin (OC) as the marker of bone formation and serum type I collagen cross-linked N-telopeptide (NTx) as the marker of bone absorption at Pre, 11th week of the intervention and Post. In CG, BMC was measured annually without the intervention. In ExG, OC was not changed, but NTx was significantly decreased by intervention (p<0.05). The decreased amount of annual change in BMC between a year before and Pre (T1) was significantly higher compared to that between Pre and Post (T2) (p<0.01) and CG (p<0.001). There was no significant difference between T2 and CG. In conclusion, BS with LT could prevent decreasing BMC in menopausal women, and maintain the same level of BMC in pre-menopausal women by suppressing the bone absorption.
