A static, unilateral, and focal bone depression located lingually within the ascending ramus, identical to the Stafne's bone cavity of the angle of the mandible, is being reported. During development of the mandible, submandibular gland inclusion may lead to the formation of a lingual concavity, which could contain fatty tissue, blood vessels, or soft tissue. However, similar occurrences in the ascending ramus at the level of the parotid gland are extremely rare. Similar cases were previously reported in dry, excavated mandibles, and 3 cases were reported in living patients. A 52-year-old African American male patient was seen for pain in the mandibular teeth. Panoramic radiography showed an unusual concavity within the left ascending ramus. Cone-beam computed tomography confirmed this incidental finding. The patient was cleared for the extraction of non-restorable teeth and scheduled for annual follow-up.

INTRODUCTIONTraditional Chinese Medicine or Traditional Complementary Medicine (TCM) is commonly used in our culture. There are several concerns regarding its use in patients undergoing conventional treatments for breast cancer. In this study, we aimed to evaluate the prevalence and pattern of TCM use among our breast cancer patients, and to identify patients who were most likely to choose TCM.
MATERIALS AND METHODSA total of 300 patients on active follow-up with Breast Service at Tan Tock Seng Hospital were interviewed using a structured questionnaire.
RESULTSA total of 35% (104 of 296) of patients reported using TCM. The majority of the patients were introduced to TCM by family and friends following the diagnosis of breast cancer. All except 3 patients continued with recommended conventional therapy although most did not inform their clinicians of TCM use. None of the patients reported any serious adverse events and 75% of them perceived a benefit from TCM use. Younger patients and those of Chinese ethnicity were more likely to use TCM (P <0.01 and P = 0.03 respectively). There was no significant difference in the dialect group, religious beliefs and educational level between the 2 groups (P >0.05).
CONCLUSIONTCM use is common among our breast cancer patients, particularly the younger women. However, most patients do not inform their clinicians of TCM use while on recommended conventional therapies. It is therefore important for clinicians to initiate discussions regarding TCM use in order to be aware of potential unwanted drug interactions.

Frailty is a distinct clinical syndrome wherein the individual has low reserves and is highly vulnerable to internal and external stressors. Although it is associated with disability and multiple comorbidities, it can also be present in individuals who seem healthy. Frailty is multidimensional and its pathophysiology is complex. Early identification and intervention can potentially decrease or reverse frailty, especially in the early stages. Primary care physicians, community nurses and community social networks have important roles in the identification of pre-frail and frail elderly through the use of simple frailty screening tools and rapid geriatric assessments. Appropriate interventions that can be initiated in a primary care setting include a targeted medical review for reversible medical causes of frailty, medication appropriateness, nutritional advice and exercise prescription. With ongoing training and education, the multidisciplinary engagement and coordination of care of the elderly in the community can help to build resilience and combat frailty in our rapidly ageing society.

Germany owns the largest herbal market in Europe and has the world's leading R&D capabilities for herbal medicine products. Chinese herbal medicine (CHM) spreaded to Germany hundreds of years ago. Since the beginning of the 20th century, China and Germany have signed a series of agreements to support traditional medicine cooperation, and the exchange of herbs between China and Germany has become more frequent, bringing opportunities for CHM to enter into Germany. In recent years, China and Germany have gained progress in the fields of CHM research and trade, etc. However, there are differences in the understanding of herbal medicines, quality standard evaluation, usage, and medication rules between the two countries. By doing SWOT analysis of the development of CHM in Germany, this paper suggested to promote Sino-German medical exchanges and build a community of common health for mankind through strengthening the clinical application of CHM, finding new ways of CHM entering into German market, and building an international talent team of traditional Chinese medicine.

BACKGROUNDLigament reconstruction tendon interposition (LRTI) is the most commonly performed surgical procedure for first carpometacarpal joint osteoarthritis. The purpose of this study was to examine the radiographic and clinical outcomes of LRTI arthroplasty and document the clinical results based on metacarpal subsidence.
METHODSFrom January 2008 to January 2011, 19 patients (21 thumbs) underwent surgery for thumb carpometacarpal arthritis using ligament reconstruction tendon interposition arthroplasty with flexor carpi radialis (FCR) in Kleinert Kutz Hand Care Center of Louisville University, USA. The follow-up period was an average of 13.9 months. Pain, grip strength, tip pinch strength, range of motion, and radiographic measurements were recorded. Based on first metacarpal subsidence, the cases were classified in to mild, moderate, and severe. Clinical outcomes of the groups were evaluated and compared.
RESULTSGrip strength improved from 18.6 kg to 20.5 kg, and tip pinch strength increased from 4.4 kg to 4.5 kg after the surgery. Radial abduction and palmar abduction improved after surgery. Radial abduction increased from 55.7° to 60.6° and palmar abduction improved from 56.7° to 63.5° after the procedure. Visual analogue scores (VAS) were significantly reduced, from 6.6 to 0.5. Compared with the preoperative radiographs the first metacarpal had subsided about 54.6% of the arthroplasty space. The height of arthroplasty space and index of the arthroplasty space significantly decreased from 12.4 mm to 5.6 mm and from 0.27 to 0.12 respectively. Between the various groups (mild, moderate and severe metacarpal subsidence), there was no difference in grip strength, tip pinch strength, thumb range of motion, and VAS.
CONCLUSIONSLigament reconstruction tendon interposition arthroplasty resulted in excellent relief of pain and increase in range of motion. However, LRTI cannot maintain the arthroplasty space. Compared with the preoperative radiographs, the metacarpal subsided more than 50%. The amount of first metacarpal subsidence has no bearing on the results.

Mesenchymal stem cells (MSCs) are characterized by their self-renewing capacity and differentiation potential into multiple tissues. Thus, management of the differentiation capacities of MSCs is important for MSC-based regenerative medicine, such as craniofacial bone regeneration, and in new treatments for metabolic bone diseases, such as osteoporosis. In recent years, histone modification has been a growing topic in the field of MSC lineage specification, in which the Su(var)3-9, enhancer-of-zeste, trithorax (SET) domain-containing family and the Jumonji C (JmjC) domain-containing family represent the major histone lysine methyltransferases (KMTs) and histone lysine demethylases (KDMs), respectively. In this review, we summarize the current understanding of the epigenetic mechanisms by which SET domain-containing KMTs and JmjC domain-containing KDMs balance the osteogenic and adipogenic differentiation of MSCs.

INTRODUCTION:
Our aim was to study the prevalence of frailty and its associated factors in a subacute geriatric ward.
METHODS:
This was a cross-sectional study of 167 participants between June 2018 and June 2019. Baseline demographics and participants' Mini Nutritional Assessment, Geriatric Depression Scale, Mini Mental State Examination, Charlson's Comorbidity Index and LACE index scores were obtained. Functional measurements such as modified Barthel's Index scores and hand grip strength (HGS) were taken. Frailty was assessed using the Clinical Frailty Scale (CFS) and the FRAIL scale. Data on history of healthcare utilisation, medications, length of stay, selected blood investigations and presence of geriatric syndromes were also collected.
RESULTS:
The prevalence of pre-frailty (CFS 4) and frailty (CFS ≥ 5) was 16.2% and 63.4%, respectively. There were significant associations between CFS and age (pre-frail vs. non-frail: odds ratio [OR] 1.14, 95% confidence interval [CI] 1.04-1.25, P = 0.006; frail vs. non-frail: OR 1.08, 95% CI 1.01-1.15, P = 0.021), HGS at discharge (frail vs. non-frail: OR 0.90, 95% CI 0.82-0.99, P = 0.025), serum albumin (frail vs. non-frail: OR 0.90, 95% CI 0.82-0.99, P = 0.035) and the presence of urinary incontinence (frail vs. non-frail: OR 3.03, 95% CI 1.19-7.77, P = 0.021).
CONCLUSION
Frailty is highly prevalent in the subacute geriatric setting and has many associated factors. In this study, independent factors associated with frailty were age, HGS at discharge, serum albumin and urinary incontinence. This has implications for future resource allocation for frail older inpatients and may help direct further research to study the effectiveness of frailty-targeted interventions.

BACKGROUND:
Recent findings on emergency department (ED) patient experience surveys and concerns for the low response rates challenge the quality and reliability of the survey reports. We assessed the consistency of an ED patient experience survey report and identified the effects of patient demographics on ED patient experiences.
METHODS:
We conducted a prospective, cross-sectional study at a university-based ED from July to December 2017. We obtained ED patient experience scores from an institutional version (IS) survey and the Press Ganey Associates-distributed survey (PGA). We compared top box scores from the two reports using frequency analysis and performed multivariable logistic regressions to identify associations between IS patient demographics and scores.
RESULTS:
We obtained 289 PGA and 234 IS responses. The IS reported significant, higher top box scores in doctor-specific patient questions compared to PGA (all four P-values < 0.01). Female, Christian and White patients were more likely to give top box scores (OR 3.07, OR 2.22 and OR 2.41, P-value < 0.05, respectively).
CONCLUSION
We found significant differences in ED patient experience scores between the IS and PGA surveys. We recommend that healthcare providers consider patient demographic variables when interpreting ED experience score reports. Multiple survey techniques and distribution methods may be adopted to best capture ED patient experiences.
