Abstract
INTRODUCTION Minimally invasive parathyroidectomy has advantages over the traditional bilateral neck exploration for the surgical treatment of primary hyperparathyroidism. It requires accurate localisation of the parathyroid pathology prior to surgery. The best method of preoperative localisation in a district general hospital setting is not well understood. METHODS All patients who underwent parathyroidectomy for primary hyperparathyroidism from 2008 to 2016 were identified from a prospectively maintained database. Operative findings were correlated with radiological and histological results. Sensitivity and specificity of ultrasound, sestamibi scintigraphy and the two together were calculated for diagnostic precision and compared. RESULTS One hundred and eighty-four patients met the inclusion criteria, of whom 81.5% had a histological diagnosis of a parathyroid adenoma. Ultrasound had higher sensitivity than sestamibi scintigraphy. Used together, ultrasound and sestamibi scintigraphy performed better than either ultrasound or sestamibi scintigraphy alone (P< 0.001). Twenty-two of 184 cases had no lesion located by either ultrasound or sestamibi scintigraphy preoperatively. Where neither ultrasound nor sestamibi scintigraphy located the lesion, additional computed tomography led to the excision of parathyroid pathology in one in ten patients. CONCLUSION The combination of ultrasound and sestamibi scintigraphy provides the highest sensitivity of preoperative localisation. This approach led to a high success rate of minimally invasive parathyroidectomy. Where preoperative localisation is not achieved with ultrasound or sestamibi scintigraphy, computed tomography adds little additional benefit. In this setting other modalities of localisation such a selective venous sampling, intraoperative methylene blue or intraoperative parathyroid hormone levels could be considered.

Abstract
OBJECTIVE We examined whether skeletal muscle mass and lower extremity functioning are closely associated with multiple cognitive domains, including global cognition, memory, attention, executive functioning, and processing speed, in community-dwelling older Japanese adults. DESIGN A cross-sectional, population-based community study. SETTING This study was conducted among community-living older people enrolled in the Obu Study of Health Promotion for the Elderly. PARTICIPANTS Participants comprised 5,104 adults (≥ 65 years, mean age: 71 years). MEASUREMENTS Data from 4273 participants were analyzed. Appendicular skeletal muscle mass was estimated from bioelectrical impedance analysis and expressed as appendicular skeletal muscle mass index (ASMI). Lower-extremity functioning was assessed by the Five-Times-Sit-to-Stand test (FTSS) and Timed Up and Go test (TUG). Cognitive functions were assessed by the Mini Mental State Examination, word list memory, Trail Making Test parts A and B, and Symbol Digit Substitution Task. Logistic regression analysis were performed to calculate odds ratios (ORs) of cognitive impairment in various domains among skeletal muscle mass, lower-extremity functioning levels adjusted for important demographic variables, and comorbidities. RESULTS Participants with lower ASMI and slower FTSS and TUG groups had lower cognitive functioning scores than did participants with higher ASMI and faster FTSS and TUG. The slowest quartiles (Q4) of FTSS and TUG were significantly associated with impaired global functioning (MMSE score < 24) compared to the fastest quartile (Q1) after multivariate adjustment (FTSS, OR = 1.46, 95% confidence interval (CI) = 1.12-1.90; TUG, OR = 1.65, 95% CI = 1.25-2.17). In other dimensions of cognitive functioning, FTSS and TUG were significantly associated with all cognitive impairment in the full adjustment model. CONCLUSION Lower-extremity functioning, rather than skeletal muscle mass, is closely related to multiple cognitive domains. This study suggests that maintaining lower-extremity functioning, rather than skeletal muscle mass, may be required for detecting and preventing cognitive impairment.

Abstract
OBJECTIVE Our study aimed to elucidate the interactive relationship between factors associated with dental caries in school children using decision tree analysis. RESEARCH DESIGN Cross-sectional study Methods: Participants were recruited from public primary schools (9-12 years, 4th to 6th grade) and junior high schools (12-13 years, 1st grade) in Japan. A total of 1775 students (928 boys and 847 girls) were analyzed. Questionnaire survey, oral examination, and saliva test were performed. Multiple logistic regression and decision tree analysis were performed. RESULTS Multiple logistic regression showed an association between dental caries and toothpaste use, dental attendance and the presence of Streptococcus mutans. Decision tree analysis showed that students with non-regular dental attendance were at a significantly higher risk of dental caries at the late stage of primary school. At the early stage of primary school, high levels of Streptococcus mutans and male sex were factors associated with dental caries. In students with low levels of Streptococcus mutans, using toothpaste occasionally was associated with a high risk of dental caries. CONCLUSIONS In early primary school years, S. mutans may be a useful screening and diagnostic tool for dental caries. In students with high levels of S. mutans, sex may be associated with dental caries. Furthermore, in students with low levels of S. mutans, regular use of toothpaste should be encouraged, and in late primary school years, regular dental attendance should be encouraged to prevent dental caries.

Abstract
SummaryThirty-eight patients bitten by Bothrops jararaca were investigated. Twenty-six had signs of local or systemic haemorrhage. Twenty-two of these had incoagulable blood, and these patients were found to have low fibrinogen levels (mean 0.17 ± 0.03 g/1), thrombocytopenia, very high thrombin-antithrombin III complex (850 ± 184 pg/1) and D-dimer (170 ± 44 μg/ml) antigen levels. Serum venom haemorrhagin levels were significantly higher in patients with clinical signs of haemorrhage (36.4 ± 6.4 ng/ml) than those without (11.7 ± 3.7 ng/ml; p <0.002). Twelve out of 13 patients with thrombocytopenia were bleeding. High levels of thrombomodulin (22.3 ± 1.5 ng/ml) and haemorrhagin (35.7 ± 7.7 ng/ml) were detected in these 12 patients, suggesting vascular endothelial damage. Haemorrhagin levels also correlated inversely with platelet count in these patients. It was concluded that thrombocytopenia is one of the main causes of bleeding inB. jararaca victims, possibly as a result of venom haemorrhagin activity.

Abstract
Background The majority of patients with primary hyperparathyroidism (PHPT) have a single overactive adenoma. Advances in preoperative imaging and surgical adjuncts have given rise to minimally invasive parathyroidectomy (MIP), with lower complication rates in comparison with bilateral neck exploration. Misdiagnosis and undertreatment of multiglandular disease, leading to potentially higher recurrence rates, remains a concern. This study evaluated risks of long‐term (1 year or more) recurrence following ‘targeted’ MIP in PHPT. Methods Multiple databases were searched for studies published between January 2004 and March 2017, looking at long‐term outcomes (1 year or more) following targeted MIP for PHPT. English‐language studies, with at least 50 patients and a mean follow‐up of 1 year, were included. Results A total of 5282 patients from 14 studies were included. Overall mean recurrence and cure rates were 1·6 (range 0–3·5) and 96·9 (95·5–100) per cent respectively. Mean follow‐up was 33·5 (1–145) months. When intraoperative parathyroid hormone (PTH) measurements were not done, cure rates were higher (99·3 per cent versus 98·1 per cent with use of intraoperative PTH measurement; P < 0·001) and recurrence rates lower (0·2 versus 1·5 per cent respectively; P < 0·001). Conclusion Targeted MIP for a presumed single overactive adenoma was associated with very low recurrence rates, without the need for intraoperative PTH measurement when preoperative imaging studies were concordant. Targeted MIP should be encouraged.

Abstract
An external electric AC field with a field strength ranging from 10 V mm-1 to 30 V mm-1 and a frequency ranging from 0.1 kHz to 1 MHz was applied to suspensions of gold nanoparticles (Au NPs) to control their plasmonic properties. Apparent differences in the UV-vis spectra of the Au NPs were observed between the spectra with and without the field application. The characteristic red color of the Au NP suspension darkened; this suggested that the application of the AC field caused the aggregation of the Au NPs. In addition, the sizes of the Au NP clusters in suspension formed by the AC field application depended on the frequency of the applied field. The surface-enhanced Raman scattering (SERS) effects of Au NP clusters were examined by comparing the difference in Raman intensities obtained at 30 V mm-1 and in a frequency range of 0.1 kHz to 1 MHz. The application of a low-frequency field at 0.1 kHz caused a rapid aggregation of the Au NPs, resulting in low Raman intensities of the probe molecules. Conversely, high-frequency applications between 1 kHz and 1 MHz successfully enhanced the Raman intensities of the molecules in suspension. The strong correlation of the optical/sensing properties with the Au NP clustering states reveals that the application of an AC electric field is a powerful tool for control over the plasmonic properties.

Abstract
OBJECTIVE An increase in coronal laxity is recognized as a risk factor for progression of knee osteoarthritis (OA). The purpose of this study was to evaluate coronal laxity, which was defined as the angular motion from the neutral, unloaded (baseline) position to the loaded position, in patients with advanced medial knee OA. METHOD Preoperative coronal laxity was assessed using radiographs in patients with medial knee OA undergoing total knee arthroplasty by applying a force of 150 N with an arthrometer. A consecutive series of 211 knees with OA and 40 normal control knees were examined. A knee with OA was defined as clinically "balanced" when the difference between medial and lateral laxity was 3° or less. Values are expressed as median [25th, 75th percentile]. RESULTS The laxity was 4° [3, 5] from the baseline on the medial side and 3° [2, 4] on the lateral side. The distribution of medial and lateral laxity indicated that 90% (189/211) of patients fell within 3°. The equivalence test showed that the medial and lateral laxity was similar, with an equivalence margin of 3° (P < 0.001). In the control knees, the laxity was 3° [2, 4] from the baseline on the medial side and 2° [2, 4] on the lateral side. The differences between the knees with advanced OA and the controls were significant (P = 0.005, medial; P = 0.006, lateral). CONCLUSION This study showed that a clinically balanced knee was maintained even in patients with advanced medial knee OA.

Abstract
Background We retrospectively studied whether a needle guide is necessary when performing ultrasound-guided fine-needle aspiration biopsy (US-FNAB) in patients with breast tumors. Methods A total of 47 patients (50 lesions) with breast tumors underwent US-FNAB with a needle guide and 127 patients (143 lesions) underwent the procedure without a needle guide (freehand biopsy). The diagnoses obtained by US-FNAB were compared with the surgical findings. Results The sensitivity of freehand biopsy for tumors <3 cm in diameter was significantly higher than that of the needle guide technique. Conclusions We recommend performing US-FNAB without a needle guide (freehand biopsy) in order to maximize the correct preoperative diagnosis rate, especially in patients with tumors <3 cm in diameter.

Background The combination of thyroid cancer and secondary uremic hyperparathyroidism has thus far been reported in only 25 cases. Methods Here we report our experience of 19 patients with secondary hyperparathyroidism who underwent parathyroidectomy. Results Thyroid nodules were present in five patients (26.3%), including one with a benign nodule and four with papillary thyroid cancer (21.1%). Conclusion Our experience suggests that, in order to make a correct diagnosis, clinicians should consider the possibility of thyroid cancer in uremic patients with secondary hyperparathyroidism.
