RESUMO

BACKGROUND: Microalbuminuria is an early indicator for renal and cardiovascular diseases, especially among patients with diabetes mellitus (DM) and hypertension (HTN). We determined the prevalence and the factors associated with microalbuminuria among patients with type 2 DM and/or HTN in the urban areas of the Puducherry district in India. METHODS: We included 225 patients aged 40-69 years with DM and/or HTN from a non-communicable diseases (NCDs) survey conducted during 2019-2020 in the urban areas of Puducherry district. The prevalence of microalbuminuria and various biological risk factors of NCDs were assessed as per the WHO STEPS methodology. The prevalence of microalbuminuria was presented as proportions (95% CI), and the adjusted prevalence ratio (aPR) was estimated using weighted forward stepwise generalized linear modelling. P-value ≤0.05 was considered statistically significant. RESULTS: The mean (SD) age of the patients was 54 (11) years. Over one-third (38.2%) (95% CI: 31.6-44.4) of patients with DM and/or HTN had microalbuminuria. The prevalence was highest among those having both DM and HTN 48% (95% CI: 37-59), followed by those having only DM 40.6% (95% CI: 29-52.2) and only HTN 27.7% (95% CI: 18.1-38.6). The prevalence of microalbuminuria was twice (aPR = 2.1, 95% CI: 1.1-3.9) higher among women and 2.4 times (95% CI: 1.12-5.1) higher among those having both DM and HTN as compared to those with only HTN. CONCLUSION: The prevalence of microalbuminuria among patients with DM and/or HTN is concerningly high. Population-based screening for microalbuminuria, especially among women and those having both DM and HTN, needs to be undertaken in the urban areas of Puducherry district.


Microalbuminuria serves as an early indicator for kidney and cardiovascular diseases, especially among patients with diabetes mellitus (DM) and hypertension (HTN). Our study focussed on determining the prevalence of microalbuminuria among individuals with type 2 DM and/or HTN in the urban areas of the Puducherry district in India. We included 225 patients aged 40­69 years with DM and/or HTN who participated in a non-communicable diseases (NCDs) survey conducted during 2019­2020 in urban Puducherry. We found that over one-third (38.2%) of patients with DM and/or HTN had microalbuminuria. The prevalence was highest among those having both DM and HTN (48%), followed by those having only DM (40.6%) and only HTN (27.7%). The prevalence of microalbuminuria was 2.1 times higher among women than men and 2.4 times higher among individuals with both DM and HTN compared to those with only HTN. These findings highlight the concerningly high prevalence of microalbuminuria among patients with DM and/or HTN in the urban areas of Puducherry district. To address this issue, it is crucial that the public health authorities of Puducherry district implement population-based screening initiatives for microalbuminuria, particularly targeting women and individuals with both DM and HTN in the urban areas of the Puducherry district.

RESUMO

The Internet of Things (IoT) is capable of controlling the healthcare monitoring system for remote-based patients. Epilepsy, a chronic brain syndrome characterized by recurrent, unpredictable attacks, affects individuals of all ages. IoT-based seizure monitoring can greatly enhance seizure patients' quality of life. IoT device acquires patient data and transmits it to a computer program so that doctors can examine it. Currently, doctors invest significant manual effort in inspecting Electroencephalograph (EEG) signals to identify seizure activity. However, EEG-based seizure detection algorithms face challenges in real-world scenarios due to non-stationary EEG data and variable seizure patterns among patients and recording sessions. Therefore, a sophisticated computer-based approach is necessary to analyze complex EEG records. In this work, the authors proposed a hybrid approach by combining traditional convolution neural (CN) and recurrent neural networks (RNN) along with an attention mechanism for the automatic recognition of epileptic seizures through EEG signal analysis. This attention mechanism focuses on significant subsets of EEG data for class recognition, resulting in improved model performance. The proposed methods are evaluated using a publicly available UCI epileptic seizure recognition dataset, which consists of five classes: four normal conditions and one abnormal seizure condition. Experimental results demonstrate that the suggested approach achieves an overall accuracy of 97.05% for the five-class EEG recognition data, with an accuracy of 99.52% for binary classification distinguishing seizure cases from normal instances. Furthermore, the proposed intelligent seizure recognition model is compatible with an IoMT (Internet of Medical Things) cloud-based smart healthcare framework.

RESUMO

Objective: The aim of this study was to evaluate the difference in mean serum 25-hydroxy vitamin D level between migraineurs and nonmigraineurs, the association between hypovitaminosis D and migraine, and the effects of oral vitamin D supplementation on migraine-related symptoms as compared to placebo. Methods: Relevant databases were searched for observational studies and randomized-controlled trials (RCTs) which evaluated the difference in mean serum 25-hydroxy vitamin D level between migraineurs and nonmigraineurs; the association between hypovitaminosis D and migraine; and the effects of vitamin D supplementation on migraine-frequency, duration, and severity. Pooled mean difference and odds ratio were calculated (random-effects model, RevMan version 5.3). Results: Ten observational studies and two RCTs were included. The serum 25-hydroxy vitamin D level in the migraineurs was significantly lower than that in the nonmigraineurs [mean difference - 4.44 ng/mL (95% CI: -6.11, -2.77)] (low-GRADE evidence). Hypovitaminosis D was found to be significantly associated with migraine [OR: 1.95 (95% CI: 1.07, 3.58)] (low-GRADE evidence). As compared to placebo, oral vitamin D supplementation significantly reduced the monthly migraine-frequency [mean difference: -2.20 (95% CI: -3.04, -1.36)]. ,: although it did not reduce the migraine-duration [mean difference: -16.00 hours per month (95% CI: -42.77, 10.76)] and migraine-severity score [standardized mean difference: -0.23 (95% CI: -0.79, 0.32)] (moderate-GRADE evidence). Conclusion: Serum 25-hydroxy vitamin D level was significantly lower in the migraineurs than that in the nonmigraineurs, and hypovitaminosis D was significantly associated with migraine. Oral vitamin D supplementation significantly reduced migraine-frequency, but not its duration and severity.

RESUMO

INTRODUCTION: The burden and mechanisms of endocrine therapy-related bone loss are well known, while there are limited data on chemotherapy-induced bone resorption. The study aimed to evaluate the effect of cytotoxic chemotherapy on bone homeostasis among postmenopausal women with non-metastatic breast cancer. MATERIALS AND METHODS: Early and locally advanced postmenopausal non-metastatic breast cancer patients aged 45 to 65 planned for three cycles of anthracycline and four cycles of taxane chemotherapy administered along with dexamethasone (cumulative dose-256 mg) as an antiemetic from June 2018 to December 2021 were included. Bone mineral density (BMD), bone turnover markers, calciotropic hormones, pro-inflammatory cytokines, oxidative stress, and total antioxidant levels (TAS) were measured. RESULTS: We recruited 109 patients, with early 34 (31.2%) and locally advanced breast cancer 75 (68.8%) with median age 53 (45-65) years. There was a significant decrease in the % BMD at the lumbar spine, neck of the femur, and total hip post-chemotherapy. There was a significant increase in serum C-terminal telopeptide of type I collagen (CTX) and procollagen type I N-terminal propeptide (PINP) levels post-chemotherapy. PINP/CTX ratio significantly decreased post-chemotherapy. Serum 25-OH vitamin D was significantly reduced with a compensatory increase in plasma iPTH levels. The change in CTX, PINP/CTX ratio, 25-OH vitamin D, iPTH, and oxidative stress index was more pronounced during anthracycline as taxane chemotherapy. There were no significant changes in pro-inflammatory cytokine levels. CONCLUSION: Chemotherapy and dexamethasone as antiemetic resulted in significant bone loss, as evidenced by bone turnover markers. Further studies are required to understand the mechanism of chemotherapy-induced bone loss and the need for bone-strengthening agents during chemotherapy.

RESUMO

PURPOSE: The burden and mechanisms of endocrine therapy-related bone loss have been studied in detail. However, there is limited data regarding cytotoxic chemotherapy's impact on bone health. There are no definitive guidelines for bone mineral density (BMD) monitoring and treatment with bone-modifying agents during cytotoxic chemotherapy. The study's primary objective was to evaluate the changes in BMD and fracture risk assessment tool (FRAX) scores among breast cancer women on cytotoxic chemotherapy. METHODS: One hundred and nine newly diagnosed early and locally advanced postmenopausal breast cancer patients planned for anthracycline and taxane-based chemotherapy were recruited prospectively during the study period from July 2018 to December 2021. BMD of the lumbar spine, the femoral neck, and the total hip were assessed by dual-energy X-ray absorptiometry scan. BMD and FRAX scores were evaluated at baseline, end of chemotherapy, and 6 months of follow-up. RESULTS: The median age of the study population was 53 (45-65) years. Early and locally advanced breast cancers were seen in 34 (31.2%) and 75 (68.8%) patients, respectively. The duration of follow-up between two BMD measurements was 6 months. The percentage of decrease in BMD at the lumbar spine, femoral neck, and total hip were - 2.36 ± 2.90, - 2.63 ± 3.79, and - 2.08 ± 2.80, respectively (P-value = 0.0001). The median risk of major osteoporotic fracture (MOF) at 10 years (FRAX score) increased from 1.7 (1.4) to 2.7% (2.4) (P-value = 0.0001). CONCLUSION: This prospective study in postmenopausal breast cancer women shows a significant association of cytotoxic chemotherapy with the worsening of bone health in terms of BMD and FRAX score.

RESUMO

BACKGROUND: Abdominal obesities are better markers for predicting cardiovascular abnormalities than risk stratification based only on body mass index (BMI). We aimed to estimate the prevalence of abdominal adiposities using predictive equations for Asian Indian adults and to determine the prevalence of metabolically healthy subjects among those overweight/obese and with normal BMI. METHODS: A community-based survey was conducted among those aged 18-69 years in the district of Puducherry between February 2019 and February 2020. We surveyed 2,560 individuals selected through multi-stage cluster random sampling from urban and rural areas (50 wards and 50 villages, respectively) of the district. Anthropometric measurements, such as height, weight, waist circumference, and blood pressure were recorded from each participant. Fasting blood sample was collected from each alternate participant to estimate metabolic risk factors. RESULTS: Over four-fifths (85.6%; 95% CI: 84.2-86.9) and two-thirds (69.7%; 95% CI: 67.9-71.6) of the population in the district had high levels of intra-abdominal adipose tissue (IAAT) and total abdominal fat (TAF), respectively. Both the risk factors were significantly higher among women and urban population. About 43% (95% CI: 41-44.9) of the population had high abdominal subcutaneous adipose tissue (SCAT) with a significantly higher prevalence among the urban population. Among those overweight/obese (n = 773), almost all 99.4% (95% CI: 98.7-99.9) were metabolically unhealthy. Among subjects with normal BMI (n = 314), only about 2.9% (95% CI: 1.3-4.8) were metabolically healthy. CONCLUSION: We highlight the substantially high prevalence of IAAT, TAF, and SCAT in the district of Puducherry. Almost all the study population was metabolically unhealthy irrespective of their BMI levels.


The distribution of abdominal fat is a better predictor of cardiovascular abnormalities in an individual than the risk assessment based only on body mass index (BMI). We conducted a community-based cross-sectional survey to estimate the prevalence of abdominal adiposities using predictive equations for Asian Indian adults and determine the prevalence of metabolically healthy subjects among those overweight/obese and with normal BMI. We surveyed 2,560 adults aged 18­69 years in the district of Puducherry between February 2019 and February 2020. We recorded each participant's anthropometric measurements, such as height, weight, waist circumference, and blood pressure and collected a fasting blood sample to assess their metabolic health status. Over four-fifths (85.6%) and two-thirds (69.7%) of the population in the district had high levels of intra-abdominal adipose tissue (IAAT) and total abdominal fat (TAF), respectively. Nearly half (43%) of the population had high abdominal subcutaneous adipose tissue (SCAT). Both the risk factors were substantially higher among women and the urban population. Among those overweight/obese, almost all (99.4%) were metabolically unhealthy; among those with normal BMI, only about 2.9% were metabolically healthy. From this study, we highlight the immediate need for population-based health promotion interventions, especially among women and urban residents of Puducherry district.

RESUMO

BACKGROUND AND AIM: The World Health Organization has revised the cardiovascular disease (CVD) risk prediction charts in 2019 for each of the 21 Global Burden of Disease regions. These charts (non-lab and lab versions) estimate the total CVD risk in an individual, of which the non-lab is for low-resource settings. We aimed to estimate the burden of ten-year risk of fatal or non-fatal CVD event in the district of Puducherry in India using 'non-lab' and 'lab' versions of WHO CVD risk prediction charts, and to evaluate the agreement between them. METHODS AND RESULTS: We included 710 individuals aged 40-69 years who participated in a district wide non-communicable diseases survey conducted in Puducherry, India, during 2019-20. Both charts use information on age, gender, systolic blood pressure and smoking status. Additionally, lab-chart requires individual's status on diabetes mellitus and total cholesterol while non-lab requires body mass index. Population in different CVD risk levels was presented using proportions (95% confidence intervals). Agreement between lab and non-lab charts was evaluated using Cohen's Kappa (k). The lab and non-lab charts estimated 3% (95% CI: 1.7-4.2) and none of the population respectively, to have high risk (≥20%) for fatal or non-fatal CVD event over the next ten years. Both the charts showed 89.4% (95% CI:87.2%-91.7%) concordance in CVD risk prediction indicating a good level of agreement (k = 0.653). CONCLUSION: WHO updated CVD risk prediction charts are feasible to apply when data is available and there is good agreement between non-lab and lab based charts.

RESUMO

Background: Settings-based approach has received lot of attention under WHO renewed strategy of health promotion. It advocates regular screening/health check-ups of employees to maintain a healthy workplace. This study aimed to assess prevalence of metabolic syndrome (MetS) among faculty members and its association with selected sociodemographic, behavioral and biochemical parameters, and to determine the 10-year fatal or nonfatal cardiovascular risk using WHO-ISH risk chart. Methodology: A cross-sectional study was conducted among 252 teaching faculty members using standardized international protocols to measure behavioral risk factors (smoking, alcohol consumption, diet pattern, physical activity, sleep, and stress), physical characteristics (weight, height, waist and hip circumferences, and blood pressure), and biochemical parameters (fasting glucose and lipid profile). Risk factor profiling was done using WHO/ISH risk prediction chart. Results: Among 252 participants (males: 172 and females: 80), 58 (24.1%) were with MetS. Prevalence was higher in males (24.6%) than females (22.6%). The younger doctors (≤40 years) had lesser prevalence of MetS compared with the elderly (>40 years) doctors (20.3% vs. 26%). Age and diet pattern were found to be independently associated with MetS. The risk of having a cardiovascular event in 10 years was <5% (low risk) for 87.5% of study participants. Conclusion: Although we included doctors who are probably the most health-conscious population, we have found that one in four have a chance of having MetS. There is a need for periodic screening program and lifestyle modification strategies to control the burden of MetS among doctors.

RESUMO

Hand gesture recognition is one of the most effective modes of interaction between humans and computers due to being highly flexible and user-friendly. A real-time hand gesture recognition system should aim to develop a user-independent interface with high recognition performance. Nowadays, convolutional neural networks (CNNs) show high recognition rates in image classification problems. Due to the unavailability of large labeled image samples in static hand gesture images, it is a challenging task to train deep CNN networks such as AlexNet, VGG-16 and ResNet from scratch. Therefore, inspired by CNN performance, an end-to-end fine-tuning method of a pre-trained CNN model with score-level fusion technique is proposed here to recognize hand gestures in a dataset with a low number of gesture images. The effectiveness of the proposed technique is evaluated using leave-one-subject-out cross-validation (LOO CV) and regular CV tests on two benchmark datasets. A real-time American sign language (ASL) recognition system is developed and tested using the proposed technique.

RESUMO

BACKGROUND: Breast cancer (BC) is one of the most common malignancies worldwide. Although the burden and mechanisms of endocrine therapy-related bone loss are known, the evidence is scanty regarding the impact of cytotoxic chemotherapy on bone health. We have attempted to summarize the effect of cytotoxic chemotherapy on bone health in BC patients. METHODS: A comprehensive literature search was performed via MEDLINE and Cochrane library databases to evaluate the effect of chemotherapy on bone health among women with BC. We included articles related to skeletal-related events, bone mineral density, bone turnover markers, osteoporosis-specific quality of life, bisphosphonate, and other bone-directed therapy. We excluded articles that included patients with metastatic breast cancer and patients receiving hormonal therapy. DISCUSSION: Bone microenvironment in cancer is directly or indirectly influenced by clinical, hormonal, nutritional, and treatment factors. Calcitonin, parathyroid hormone, calcitriol, and estrogen are the major hormonal regulators. Bone turnover markers, namely bone formation and resorption markers, have been used to predict bone loss, fracture risk, and monitoring treatment response. Chemotherapeutic drugs such as anthracyclines and taxanes synergistically affect BMD and quality of life. Calcium, vitamin D, bisphosphonates, and denosumab are supplemented to prevent excess bone resorption. Bone-targeted anti-resorptive agents have been studied as potential anticancer agents in the adjuvant treatment of breast cancer. CONCLUSION: This review summarizes the negative effect of chemotherapy on bone health of BC patients and the importance of preventing or treating bone loss.

RESUMO

BACKGROUND: Obesity has a strong association with the risk of developing cognitive impairment and dementia at a later age. Brain-derived neurotrophic factor (BDNF) and its receptor appear to be important components in cognitive function and are also involved in energy homeostasis. The level of circulating BDNF and its association with cognition has yet to be delineated clearly. In this work we studied the association of circulating BDNF with cognition among the adult obese population. METHODS: The study involved 132 healthy participants between 18 and 40 years of age and of both sexes. The participants were categorized into an obesity group (n=66) and a non-obese group (n=66) based on their body mass index (Asian criteria). The level of cognitive performance was assessed by the event-related potentials P300 (ERPs-P300), mini-mental state examination (MMSE), both visual and auditory reaction times (VRT and ART, respectively), and other pen and paper tests related to memory and executive function. Serum BDNF, glycemic and lipid profiles were estimated. RESULTS: We found significant differences in the ERPs-P300 latency (P<0.001) and amplitude (P=0.002) between the non-obese and obese group. The MMSE score was significantly reduced while VRT (P=0.005) and ART (P=0.001) were larger in the obese group. BDNF levels (P<0.001) were significantly reduced and negatively associated with the obese group. ERPs-P300 latency was negatively associated (r=-0.674, P=0.001) whereas amplitude (r=0.507, P<0.001) was positively associated with the BDNF levels in the adult obese population. CONCLUSION: We found reduced circulating BDNF levels in obese adults and that lower BDNF levels were strongly associated with cognitive decline in the obese adult population.

RESUMO

BACKGROUND: Chronic urticaria (CU) is a debilitating inflammatory skin disease. Prior studies have shown reduced concentrations of vitamin D in CU and there are limited reports of potential beneficial role for vitamin D supplementation in the treatment of subjects with CU. We assessed the effect of vitamin D supplementation in vitamin D deficient CU patients on the clinical outcome and inflammatory markers in South Indian patients with CU. METHODS: This randomized controlled trial involved 120 vitamin-D deficient CU patients. Urticaria activity score (UAS7) and autologous plasma skin test (APST) status was assessed in all cases. CU patients were supplemented with vitamin D with a dose of 60,000 IU fortnightly for a period of 12 weeks and those in the placebo arm received matched placebo. Five milliliters of blood was drawn from all study subjects at baseline and after 12 weeks for assessing inflammatory markers. RESULTS: We observed a significant reduction in UAS7 scores after 12 weeks in the vitamin D treated group in comparison to that of placebo. We also noted a significant reduction of the inflammatory cytokines in the vitamin D treated group. CONCLUSION: Supplementation with vitamin D among patients with vitamin D deficient CU significantly decreases disease severity which is probably mediated through reduction of systemic inflammation.

RESUMO

Metastatic pulmonary calcification (MPC) is an uncommon entity resulting from abnormalities in calcium-phosphorus homoeostasis. Most cases reported in the literature are among patients with chronic kidney disease receiving haemodialysis. Primary hyperparathyroidism is a relatively common condition affecting calcium homoeostasis, in which MPC can rarely occur. We report the case of one such patient who presented with severe hypercalcaemia and features of interstitial lung disease. Radiographic imaging was normal and the diagnosis was clinched by diffuse pulmonary uptake in 99mTechnetium-methylene diphosphate scan.

RESUMO

AIMS: To evaluate the effect of metformin on various parameters of exercise capacity [oxygen consumption (VO2), peak oxygen consumption (VO2peak), heart rate (HR), exercise test duration, respiratory exchange ratio (RER), rating of perceived exertion (RPE), lactate and ventilatory anaerobic threshold (VAT)]. METHODS: Studies reporting change in VO2 or VO2peak after metformin administration were included. Subgroup analyses were performed as applicable. Mean difference with 95% CIs were pooled using random-effects model [RevMan (v5.3)]. RESULTS: There were no changes in VO2 and VO2peak in the overall population [VO2: n = 388, mean difference: -0.12 ml/kg/min, 95% CI: -0.74, 0.51, p = 0.71 (i2 = 0%, p = 0.99); VO2peak: n = 345, mean difference: 0.41 ml/kg/min, 95% CI: -0.51, 1.33, p = 0.38 (i2 = 0%, p = 0.89)], healthy volunteers and patients (type 2 diabetes mellitus, insulin resistance, impaired glucose tolerance/impaired fasting glucose and metabolic syndrome). For patients with insulin resistance, there was a decrease in VO2peak, but not VO2. In the overall population, there was a significant decrease in HR and RER, a significant increase in RPE, and no changes in exercise test duration and VAT. In addition, there was an increased VAT in the healthy volunteers. CONCLUSIONS: In the overall population, metformin did not affect VO2, VO2peak, exercise test duration and VAT, although it significantly decreased HR, RER and increased RPE.

RESUMO

Both chronic kidney disease (CKD) and hypothyroidism are associated with decreased serum irisin level. The presence of hypothyroidism may influence serum irisin level in CKD patients. The objective of this study was to evaluate the effect of hypothyroidism on serum irisin level in patients with nondiabetic CKD. Two hundred nondiabetic CKD patients aged between 18 and 65 years with glomerular filtration rate <60 mL/min/1.73 m2 were included in this study. Forty-three (21.5%) patients had hypothyroidism (overt and subclinical both). Forty hypothyroid and forty euthyroid CKD patients matched for age and Body Mass Index underwent body composition, biochemical [fasting plasma glucose (FPG) and C-reactive protein], and hormonal (fasting irisin and insulin) evaluation. Body composition analysis including visceral adipose tissue was done by dual-energy X-ray absorptiometry. Homeostatic model assessment 2 insulin resistance was calculated from FPG and insulin levels. The median serum irisin levels were not significantly different between hypothyroid and euthyroid CKD patients [95 (47.74-261.52) vs. 66 (28.25-224.50) ng/mL, P = 0.30]. There was also no difference in renal function, body composition and other metabolic parameters between the two groups. To conclude, the presence of hypothyroidism does not alter serum irisin level in patients with nondiabetic CKD.

RESUMO

BACKGROUND: Frey's procedure involves both drainage and resection of the pancreas in subjects with chronic calcific pancreatitis (CCP). The procedure may affect the pancreatic endocrine function after surgery. The present study was to evaluate the effect of Frey's procedure on both beta and alpha cell function in CCP patients. METHODS: Thirty CCP patients who underwent Frey's procedure were included. According to the glycemic status, patients were divided into the diabetes mellitus (DM), prediabetes, and normal glucose tolerance (NGT) groups. Islet cell function was assessed before and 3 months after surgery. RESULTS: At baseline, there was a significant difference in beta cell function among the three groups [NGT group 1.71 (1.64-2.07) vs prediabetes group1.50 (0.83-1.61) vs DM group 0.33 (0.12-0.55), P < 0.0001], but the insulin resistance was not different among them. Post glucose hyperglucagonemia representing alpha-cell dysfunction during oral glucose tolerance test was present in all of them, but showed no significant difference [NGT group 0.15 (0.06-0.31) vs prediabetes group 0.32 (0.05-0.70) vs DM group 0.07 (0.02-0.18), P = 0.20]. Frey's procedure did not change beta cell function and insulin resistance. However, alpha-cell dysfunction deteriorated after surgery [0.10 (0.03-0.27) vs 0.33 (0.09-0.68), P = 0.004]. CONCLUSIONS: Although Frey's procedure does not affect the beta cell function and insulin resistance in CCP patients, the alpha-cell dysfunction deteriorates after surgery.

RESUMO

Osteoporosis is the most common metabolic bone disorder worldwide, especially in women. Postmenopausal status is the most common risk factor for osteoporosis in elderly women. The operational diagnosis of osteoporosis is usually made with the help of central dual energy X-ray absorptiometry scan. Clinically, osteoporosis is suspected in the background of one or more fractures of the hip, vertebra, proximal humerus or pelvis in the absence of local disease or high-energy trauma. Serious underlying illness can present with vertebral fractures and can be missed if other clues from clinical examination and investigations are overlooked. We report a case emphasising this aspect.
