Background: Thailand is one of the developing countries encountering medical workforce shortage. From the national registry in 2006, there were 33 166 physicians: 41.5% worked in the government sector, 21.6% worked in the private sector, and the remaining worked in non-medical fields. There is no current data to confirm the effectiveness of the national policy to increase physician production. We demonstrate our findings from the strength, weakness, opportunity, and threat (SWOT) analysis in medical students and the potential impact on national workforce planning. Methods: We introduced SWOT analysis to 568 medical students during the 2008–2010 academic years, with the objective of becoming “a good physician in the future”. Results: Pertinent issues were grouped into 4 categories: not wanting to be a doctor, having inadequate medical professional skills, not wanting to work in rural or community areas, and planning to pursue training in specialties with high salary/low workload/low risk for lawsuit. The percentages of medical students who described themselves as “do not want to be a doctor” and “do not want to work in rural or community areas” increased from 7.07% and 25.00% in 2008 to 12.56% and 29.65% in 2010, respectively. Conclusion: Further intervention should be considered in order to change the medical students’ attitudes on the profession and their impact on Thai health system.

STUDY DESIGN: A prospective cohort. PURPOSE: To report the short and long term outcomes of fluoroscopically guided lumbar transforaminal epidural steroid injection (TFESI) in degenerative lumbar spondylolisthesis (DLS) patients. OVERVIEW OF LITERATURE: TFESI has been widely used for the treatment of lumbosacral radicular pains. However, to our knowledge, there has been no study which has evaluated the outcomes of TFESI in patients with DLS. METHODS: The DLS patients received fluoroscopically guided lumbar TFESI with 80 mg of methylprednisolone and 2 mL of 1% lidocaine hydrochloride. Patients were evaluated by an independent observer before the initial injection, at 2 weeks, at 6 weeks, at 3 months, and at 12 months after the injections. Visual analog scale (VAS), Roland 5-point pain scale, standing tolerance, walking tolerance, and patient satisfaction scale were evaluated for outcomes. RESULTS: Thirty three DLS patients treated with TFESI, who were completely followed up, were included in this study. The average number of injections per patient was 1.9 (range from 1 to 3 injections per patient). Significant improvements in VAS and Roland 5-point pain scale were observed over the follow up period from 2 weeks to 12 months. However, the standing and walking tolerance were not significantly improved after 2 weeks. At 2 weeks, the patient satisfaction scale was highest, although, these outcomes declined with time. The DLS patients with one level of spinal stenosis showed significantly better outcome than the DLS patients with two levels of spinal stenosis. Five patients (13%) underwent surgical treatment during the 3 to 12 months follow up. CONCLUSIONS: TFESI provides short term improvements in VAS and Roland 5-point pain scale, standing tolerance, walking tolerance and patient satisfaction scale in DLS patients. In the long term, it improves VAS but limits the improvements in Roland 5-point pain scale, standing tolerance, walking tolerance and patient satisfaction scale.

INTRODUCTIONThis study aimed to evaluate radiological findings in patients with chondroblastoma (CB) in tubular and non-tubular bones (NTBs).

METHODSWe retrospectively reviewed the medical records of patients with CB. Data collected included patients' gender and age, type, size and location of bone involved, and imaging findings regarding border, lobulation, calcification, trabeculation, cortical expansion and destruction, periosteal reaction, soft tissue component and fractures. Magnetic resonance imaging and/or multidetector computed tomography were used to determine the presence of any internal cystic space or secondary aneurysmal bone cyst that may have affected the radiological appearance of CB.

RESULTSAll 31 lesions (18 tubular bones, 13 NTBs) exhibited geographic bone destruction and did not involve the adjacent joints. Univariate analysis showed that NTB lesions were found in older patients and were associated with thin trabeculation (p < 0.01) and well-defined margins (p < 0.05), whereas tubular bone lesions correlated with thick trabeculation and partially ill-defined margins. On multivariate analysis, age and type of bone involvement were significantly correlated. An increase in age by one year reduced the risk of having tubular bone involvement by about 27% when compared with NTBs (p = 0.011). Thin trabeculation was also significantly correlated with NTB lesions.

CONCLUSIONAge was the most significant parameter, as increased age was found to reduce the risk of tubular bone involvement. Patients with NTB lesions were significantly older than those with tubular bone lesions. Based on imaging alone, thin trabeculation showed significant correlation with CB occurring in NTBs on both univariate and multivariate analyses.

Objectives: Ankle fractures are common in the elderly. However, their association with osteoporosis remains controversial. This systematic review aims to determine the relationship between ankle fracture and bone mineral density (BMD), and to investigate the risk of subsequent fractures after ankle fracture. Methods: MEDLINE and Scopus publications were searched from inception to March and April 2019, respectively. Articles were selected by 2 independent reviewers for cross-sectional, cohort, or casecontrol studies comparing BMD or subsequent fracture risk in low-energy ankle fractures patients with that of the normal population. Data extraction was performed by 2 investigators. Discrepancies were resolved with the third reviewer. Quality assessment was conducted using the modified NewcastleOttawa Scale. Results: Overall, 19 articles were included. The quality assessment showed a generally low-to-moderate risk of bias among studies, mainly due to potential confounders and inadequate follow-up. Of 13 studies exploring BMD in ankle fractured-patients, lower central and peripheral BMD was found in 3 and 2 studies, respectively. The risk of subsequent fracture was examined in 11 studies with relative risks ranging from 0.7 to 4.59. An increased risk of any subsequent fractures in women, both genders, and men was found in 5, 2, and 1 articles, respectively. Conclusions Despite the lack of clear association with BMD, the contribution of ankle fracture to increased subsequent fracture risk and its associated microarchitectural changes cannot be overlooked.Moreover, its potential role as an early predictor of future fracture may promote secondary prevention.Further studies with longer follow-up and stricter confounder control are recommended.
