RESUMO

OBJECTIVES: Despite the critical value of healthcare workers (HCWs) demonstrated during the COVID-19 pandemic, there remains a noted global surge in violence against this population. The present meta-analysis aimed to gather data on the prevalence of workplace violence (WPV) against HCWs and to determine if there is any difference based on gender. STUDY DESIGN: This was a systematic review and meta-analysis. METHODS: A thorough search of PubMed/MEDLINE, Lilacs, and Cochrane Collaboration databases was conducted from the start of the COVID-19 pandemic until March 8, 2023. Two authors independently carried out screening, data extraction, and quality assessment, followed by statistical analysis using random-effects meta-analysis and subgroup analysis to assess heterogeneity. RESULTS: We included 22 studies with 44,357 participants, of which 79.37% were women. The analysis revealed an overall prevalence of WPV similar in both women (51.86%, 95% confidence interval [CI]: 41.39-62.33) and men (51.45%, 95% CI: 40.95-61.95). There were considerable differences in gender-based WPV across geographic regions. Aggressions tend to be higher toward men in Asia (odds ratio [OR] 0.79, 95% CI 0.74-0.85, P < 0.001). Conversely, in Latin America, WPV prevalence was higher in women (OR 1.20, 95% CI 1.01-1.4, P = 0.035). HCWs from low- middle-income-level countries suffered a higher incidence of violence irrespective of gender compared with high- and upper-middle-income countries (72.36% vs 47.35%). CONCLUSIONS: Our data indicate that more than half of HCWs experienced WPV during the COVID-19 pandemic. In addition, women and HCWs in low-middle-income countries were notably vulnerable to WPV. A deeper understanding of the nuances behind violence against HCWs will help to facilitate tailored strategies for different demographical contexts. REGISTRATION: PROSPERO ID: CRD42023403970.

RESUMO

OBJECTIVES: To evaluate gender differences in workplace violence (WPV) against physicians and nurses in Latin America. STUDY DESIGN: Cross-sectional study. METHODS: A cross-sectional electronic survey was conducted between January 11 and February 28, 2022. A prespecified gender analysis was performed. RESULTS: Among the 3056 responses to the electronic survey, 57% were women, 81.6% were physicians, and 18.4% were nurses. At least one act of violence was experienced by 59.2% of respondents, with verbal violence being the most common (97.5%). Women experienced more WPV than men (65.8% vs 50.4%; P < 0.001; odds ratio [OR]: 1.89; 95% confidence interval [CI]: 1.63-2.19). Women were more likely to report at least one episode of WPV per week (19.2% vs 11.9%, P < 0.001), to request for psychological help (14.5% vs 9%, P = 0.001) and to experience more psychosomatic symptoms. In addition, women were more likely to report having considered changing their job after an aggression (57.6% vs 51.3%, P = 0.011) and even leaving their job (33% vs 25.7%, P = 0.001). In a multivariate analysis, being a woman (OR: 1.76), working in emergency departments (OR: 1.99), and with COVID-19 patients (OR: 3.3) were independently associated with more aggressive interactions, while older age (OR: 0.95) and working in a private setting (OR: 0.62) implied lower risk. CONCLUSIONS: Women are more likely to experience WPV and to report more psychosomatic symptoms after the event. Preventive measures are urgently needed, with a special focus on high-risk groups such as women.

RESUMO

PURPOSE: The purpose of this prospective study was to compare the efficacy of percutaneous acetic acid (PAAI) to that of radiofrequency ablation (RFA) in the treatment of small (≤5cm) hepatocellular carcinoma (HCC) using a randomized trial. MATERIAL AND METHODS: Consecutive patients with small HCC underwent clinical, biochemical, and imaging evaluation. Those fulfilling the inclusion criteria (Child's A/B cirrhosis, less than 5 HCC nodules, HCC nodules≤5cm diameter, no extrahepatic disease, patent portal vein, normal coagulation profile with informed consent) were randomly assigned to receive RFA or PAAI. Tumor response and survival rate were estimated. Non-inferiority margin of 10% difference was taken for effectivity of PAAI compared to RFA. RESULTS: Of the 86 patients screened, 55 patients with 67 HCC nodules were included. There were 40 men and 15 women with a mean age of 54.3±10.5 (SD) years (range: 28-71years). Of these, 26 patients had PAAI and 29 had RFA. The clinical, demographic and imaging profiles of the two groups were similar. Complete response was non-inferior to RFA [PAAI 75% and RFA 83.3%, difference 8.3% CI (-12.5% to 29.2%)]. Lower limit of this 95% CI (-12.5%) was lower than the 10% non-inferiority margin difference (8.3%). Survival rates were similar at 12months (PAAI, 81.6% vs. RFA, 71.9%; P=0.68) and at 30months (PAAI, 54.4% vs. RFA, 52%; P=0.50). CONCLUSION: PAAI and RFA have similar efficacy in treating small HCC. PAAI could thus be a cost-effective alternative in situations where RFA is either unavailable or unaffordable.

RESUMO

OBJECTIVE: It is unclear whether the association between osteoarthritis (OA) and metabolic syndrome (MetS) varies with the site of the affected joint and the presence of pain. Our aim was to describe the association between MetS and radiographic OA (ROA) affecting the knee or the hand in the presence or absence of concurrent joint pain. METHODS: Cross-sectional data of 952 women, aged 45-65years from the Chingford study, a population-based longitudinal cohort of middle-aged women initiated in 1988-1989 in London (UK), was analysed. MetS was defined using the National Cholesterol Education Program Treatment Panel III criteria. Data was collected on components of MetS: waist circumference, triglycerides, high-density lipoprotein (HDL), blood pressure and blood glucose. The outcome was four knee and hand OA groups: painful ROA, ROA only, pain only and neither ROA nor pain (reference category). Multinomial logistic regression models adjusted for age and body mass index (BMI) were used to evaluate the effect of presence of MetS and its individual components on OA subgroups for knee and hand separately. RESULTS: 952 eligible women, aged 45-65years was analysed. A significant association was observed between the presence and the number of MetS with painful knee ROA when adjusted for age; however, this association disappeared when BMI was included in the model. In contrast, the presence and the number of MetS were associated with painful interphalangeal (IPJ) OA after adjusting for both age and BMI. Four out of the five MetS components, including triglycerides, HDL-c, hypertension and glucose, were associated with painful IPJ OA. CONCLUSIONS: MetS is associated with painful IPJ OA but not with knee OA once BMI is taking into consideration. Further attention to MetS and OA at different sites is needed to understand the metabolic phenotype in OA.

RESUMO

Although diaphragmatic paralysis is a rare recognized complication of chest tube malposition, Chilaiditi's sign occurring as a result of this complication has never been reported in literature to the best of our knowledge. We describe one such case, which had an interesting clinical sequence of events and radiographic findings and suggest that the medial end of the chest tube should be positioned at least 2 cm from the mediastinum on the frontal chest radiograph to avoid these complications.

RESUMO

BACKGROUND & OBJECTIVE: High resolution computed tomography (HRCT) scans are known to be helpful in early diagnosis and management of patients with miliary tuberculosis (MTB). We made an attempt in this study to identify patterns of pulmonary MTB on HRCT and to correlate the HRCT disease extent with pulmonary function tests (PFT) and gas exchange analysis (GEA). METHODS: A total of 16 non-HIV patients with MTB underwent HRCT of the chest, PFT and GEA. All the investigations in these patients were completed within 20 days of presentation. Evidence of TB was diagnosed by biopsy from lymph nodes (3/16), organ biopsy [skin, liver, bone marrow and lung (transbronchial) (6/16)]. In one patient fundoscopy revealed choroid tubercles. In 6 patients, diagnosis was confirmed by clinical/radiological improvement following anti-tuberculosis therapy. Radiological patterns of involvement on HRCT of the lungs were studied and disease extent was estimated in each case by consensus between two radiologists using specially devised visual scoring system. Disease extent was correlated with PFT and GEA. Spearman rank correlation was used for statistical analysis. RESULTS: Findings on HRCT in MTB included miliary nodularity (16/16), alveolar lesions such as ground glass attenuation and/or consolidation (5/16), lymphadenopathy (8/16), peribronchovascular interstitial thickening (1/16), emphysema (1/16), pleural pathology (2/16), and pericardial effusion (2/16). A significant correlation was noted between disease extent score and forced vital capacity (FVC) (r = -0.76; P=0.003), forced expiratory volume in one second (FEV(1))(r = -0.74; P = 0.005), total lung capacity (TLC) (r = -0.66; P = 0.037), oxygen saturation in arterial blood (SaO(2)) (r = -0.69, P = 0.01), diffusion capacity of the lung (DLco) (r = -0.8; P = 0.02). INTERPRETATION & CONCLUSION: Our findings showed that HRCT reliably diagnosed MTB, and thus could help in predicting derangement of pulmonary function tests and GEA in these patients.

RESUMO

Over the last decade, liver imaging has experienced a revolution providing a bewildering array of options for detection and characterisation of liver lesions. Cross-sectional imaging modalities like computed tomography and magnetic resonance imaging have improved in speed and resolution, thereby facilitating multiphasic scanning of the liver. The advent of the use of contrast agents for ultrasonography and magnetic resonance imaging has further paved the way for definitive diagnosis in an attempt to obviate the need for invasive diagnosis. This article captures advances made in ultrasonography, computed tomography, magnetic resonance imaging and positron emission tomography and brings the specialist up to date with the latest in liver imaging.

RESUMO

OBJECTIVE: To study the clinical profile and diagnostic methods in patients with symptomatic pulmonary embolism (PE). METHODS: Prospective assessment of clinical features, radiology and outcome of patients presenting with symptomatic PE over an 18-month period. RESULTS: During study period, 24 patients with a mean age of 39 +/- 12.1 years were diagnosed to have symptomatic pulmonary embolism. Dyspnoea (91.7%) and cough (58.3%) were the predominant complaints. Spiral computed tomographic pulmonary angiography (CTPA) was performed in 21 (87.5%) patients and perfusion scans in 14 (58.4%) patients. Echocardiography performed in all patients revealed evidence of pulmonary artery hypertension and right ventricular dyskinesia in 20 (83.3%) and 15 (62.5%) patients, respectively. Thrombolysis with streptokinase was performed in 14 (58.3%) patients. All patients received low molecular weight heparin followed by warfarin. Of the 24 patients, 20 (83.3%) were discharged and are under regular follow-up; four patients died. CONCLUSIONS: Pulmonary embolism is a common problem and can be easily diagnosed provided it is clinically suspected. Early diagnosis and aggressive management is the key to successful outcome.

RESUMO

We compared the efficacy of spironolactone (50 mg/d) with metformin (1000 mg/d) after random allocation in 82 adolescent and young women with polycystic ovary syndrome (PCOS) on body mass index (BMI), waist-to-hip ratio, blood pressure, menstrual cyclicity, hirsutism, hormonal levels, glycemia, and insulin sensitivity at baseline and at the 3rd and 6th months of treatment. Sixty-nine women who completed the follow-up had a mean age of 22.6 +/- 5.0 yr and mean BMI of 26.8 +/- 4.0 kg/m2. The number of menstrual cycles in the spironolactone and metformin groups increased from 6.6 +/- 2.1 and 5.7 +/- 2.3 at baseline to 9.0 +/- 1.9 and 7.4 +/- 2.6 at 3rd month and to 10.2 +/- 1.9 and 9.1 +/- 2.0/ year at the 6th month (P = 0.0037), respectively. The hirsutism score decreased from 12.9 +/- 3.2 and 12.5 +/- 4.9 at baseline to 10.1 +/- 3.1 and 11.4 +/- 4.1 at the 3rd month and to 8.7 +/- 1.9 and 10.0 +/- 3.3 at the 6th month, respectively. Both groups showed improvement in glucose tolerance and insulin sensitivity, although the metformin effect was significant in the latter. Serum LH/FSH and testosterone decreased in both groups. BMI, waist-to-hip ratio, and blood pressure did not change with either drug. We conclude that both drugs are effective in the management of PCOS. Spironolactone appears better than metformin in the treatment of hirsutism, menstrual cycle frequency, and hormonal derangements and is associated with fewer adverse events.

RESUMO

Idiopathic rapidly progressive glomerulonephritis (RPGN) is a clinicopathologic syndrome in which glomerular damage is accompanied by a rapid and progressive decline in renal function, usually resulting in irreversible renal failure in weeks or months. We report the occurrence of pauci-immune RPGN, more specifically microscopic polyarteritis nodosa (PAN), in a 60-year-old woman 15 months after donor nephrectomy, and 3 months after documentation of intact, residual renal function. The transplanted kidney continues to function well in the recipient, 6 years posttransplantation, and 4.5 years beyond destruction of the donor's contralateral kidney by RPGN. The donor underwent cadaveric renal transplantation after 2 years on dialysis, and at the 3-year mark has intact renal function. These intriguing observations strongly argue that host environmental factors, rather than intrarenal factors, play a major causative role in the pathogenesis of RPGN.

RESUMO

SETTING: Diagnosis of mediastinal tuberculosis (TB) is difficult due to non-specific clinical features and lack of characteristic radiographic features. Histopathological confirmation has often required computed tomography guided fine needle aspiration biopsy (FNAB) or even invasive procedures such as mediastinoscopy or open/surgical biopsy. FNAB under ultrasound (US) guidance can also be performed in this clinical setting. OBJECTIVE: To define the role of percutaneous US guided FNAB in the diagnosis of mediastinal tuberculosis. DESIGN: Twenty-six patients with a proven diagnosis of mediastinal TB formed the study group. Chest radiographs and sputum examination were negative. FNAB was performed via suprasternal (n = 20) and parasternal (n = 6) route under sonographic guidance using 22G spinal needle. Aspirates were considered positive for TB when epithelioid cell granuloma with caseation necrosis and/or the presence of Mycobacterium tuberculosis by acid-fast bacilli (AFB) or culture was demonstrated, indeterminate when epithelioid cell granulomas were seen but without caseation necrosis or AFB, and negative when aspirate contained non-representative material. RESULTS: A total of 30 biopsies were performed in the 26 patients, including repeat biopsy and biopsy of different sites in two patients each. FNAB was positive for TB in 20 of the 26 patients. In four, AFB were demonstrated, and in seven culture was positive for M. tuberculosis; in the remaining six patients, cytologic diagnosis was indeterminate in four and negative in two. No procedure related complications were noted. CONCLUSION: Ultrasound guided FNAB is a safe, effective technique in the diagnosis of mediastinal TB.

RESUMO

We report a case of a 38-year-old woman with a prosthetic mitral valve who presented with multiple embolic events. Transesophageal echocardiography was used to diagnose nonobstructive thrombi on the prosthetic valve. She underwent successful thrombolytic therapy. The patient was discovered to be in a hypercoagulable state, which probably was caused by the concomitant use of phenytoin. We review the literature for diagnosis and treatment of nonobstructive prosthetic valve thrombosis.

RESUMO

The advantages of digital echocardiography studies include ease of retrieval, review, comparison, duplication, and quantitation as well as the potential for moving studies over networks. However, the large amounts of data associated with digital echocardiography studies have posed new problems. Reduction of the amount of data can be accomplished with image compression, in particular MPEG-1 (Moving Pictures Expert Group), which is designed for dynamic image sequences. However the effects of different levels of compression on the quality and diagnostic content of echocardiographic images need to be established. Digital sequences of single cardiac cycles were acquired in 40 consecutive patients, MPEG-1-compressed at different effective ratios (60:1, 80:1, 120:1, 200:1, 300:1, 370:1, 500:1), reviewed, and scored for endocardial visualization. The overall visualization scores and percentages of nonvisualized segments in the compressed images were not different from the uncompressed images up to a compression ratio of 200:1. Differential effects of compression were noted on a segmental basis and also varied with baseline image quality. The ability to correctly identify regional wall motion abnormalities did not decrease until compression ratios of 1:200 or higher were used. Digital echocardiography loops, MPEG-1-compressed at an effective ratio of 200:1, demonstrate no degradation in endocardial visualization quality or diagnostic content. Compression at this ratio has the potential to reduce the storage size of digital echocardiography studies to less than 1% of their current size.

RESUMO

Neuropsychiatric involvement in SLE (NP-SLE) may not be picked up by routine neuroimaging procedures like computerized tomography (CT) or magnetic resonance imaging (MRI). We prospectively studied the role of single photon emission computerized tomography (SPECT) and magnetic resonance spectroscopy (MRS) in detection of NP-SLE in 20 patients with lupus (10 with clinical NP involvement and 10 without) and 9 healthy controls. MRI abnormalities were seen in 5/10 patients with NP-SLE while the MRI was normal in all the lupus patients without clinical NP involvement. Perfusion defects on SPECT were seen in as many as 8/10 patients with NP-SLE while only 1/10 lupus patients without clinical NP involvement and none of the healthy controls demonstrated perfusion defects. MRS revealed abnormal metabolite ratios in all patients with NP-SLE and as many as 8 lupus patients without clinical NP features. Normal metabolite ratios were observed in healthy controls. SPECT and MRS can help detect changes not evident on MRI and may serve as useful supplements to existing neuroimaging techniques in the diagnosis of NP-SLE. The precise significance of alterations in regional cerebral blood flow on SPECT and neurometabolite ratios on MRS needs larger, longitudinal studies.

RESUMO

Fine needle aspiration biopsy (FNAB) of focal splenic lesions has been infrequently utilized because of the risk of haemorrhage. This study was carried out to evaluate the safety and efficacy of ultrasound guided FNAB of splenic lesions. 35 patients with focal splenic lesions underwent FNAB under real-time ultrasound guidance using a free hand technique. Ultrasound findings were single or multiple focal hypoechoic lesions (n = 33), focal hyperechoic lesion (n = 1) and diffuse heterogeneous echotexture (n = 1). Aspirations were performed with 22 G spinal needles using either the subcostal or the intercostal approach. Definite cytological diagnosis was made in 22 patients (62.8%), including tuberculosis in 10 patients, lymphoma in seven patients, extramedullary haematopoiesis in two patients and aspergillosis, histoplasmosis and bacterial abscess in one patient each. FNAB was negative in 12 patients because the aspirates were either scanty or contained only blood. FNAB was falsely positive in one patient. Only one patient had significant intraabdominal bleeding, which was managed conservatively. In conclusion, splenic FNAB performed under ultrasound guidance is a safe and accurate method in the diagnosis of focal splenic lesions.

RESUMO

Abdominal tuberculosis continues to be endemic in the developing world and has shown a resurgence in the West. Computed tomography (CT) evaluation is singularly informative as it demonstrates involvement of the bowel, peritoneum, lymph nodes, and solid organs in a single examination. A spectrum of CT findings in an immunocompetent population is presented, ranging from subtle to advanced and common to rare. Genitourinary tuberculosis and tuberculosis in AIDS are excluded as they merit separate discussions.

RESUMO

The purpose of this study was to evaluate the splenoportal (SP) axis and patency of portal systemic shunts in extrahepatic portal venous obstruction (EHO) by intravenous CT portography (CTP). Fifty-five patients of preshunt EHO, and 21 patients of postshunt (surgical portal systemic shunts) EHO, were subjected to intravenous CTP on a subsecond helical CT scanner. Thin, axial sections and three dimensional (3-D) reconstructions, including maximum intensity projection (MIP) and shaded surface display (SSD), were obtained. The findings were correlated with Color Doppler Flow Imaging (CDFI). In the EHO preshunt group, the site of the block demonstrated on CTP correlated with CDFI in 53 of 55 cases. In the postshunt group, shunt patency evaluation by CTP was in agreement with CDFI in 19 of 21 patients (8 patent; 13 blocked). Two patients in each group could not be evaluated on CDFI, while CTP could provide the appropriate information. There was no false positivity or negativity with CTP in patients evaluated on both modalities. The etiology of EHO, the global view of collaterals, and the 3-D anatomy of SP axis could be well depicted and was well accepted by the surgeons. We conclude that CTP is an impressive new technique that can effectively evaluate pre- and postshunt cases of EHO.

RESUMO

PURPOSE: To compare the findings related to esophageal/gastric varices and congestive gastropathy on intravenous computed tomography (CT) portography (CTP) and upper gastrointestinal endoscopy (UGIE) in children with extrahepatic portal venous obstruction (EHO) presented with hematemesis. METHODS/MATERIALS: Fifty pediatric patients (age < 15 years) with EHO (initially diagnosed on abdominal ultrasound) presented with hematemesis and underwent UGIE and intravenous CTP using a helical CT scanner. Axial sections of 2 mm each were obtained with a collimation of 2 mm and a table feed of 3 mm. CTP findings on these axial sections were compared with UGIE (gold standard). RESULTS: The sensitivity of CTP for detection of esophageal varices, gastric varices, and gastropathy was 32/33 (97%), 38/40 (95%), and 30/32 (93%), respectively. CTP showed false positivity as well, which was 5/17 (29%), 2/10 (20%), and 13/17 (76%) for esophageal varices, gastric varices, and gastropathy, respectively. On follow-up UGIE, the endoscopic features appeared in 14/19 (74%) of false positive patients. Therefore, false positivity for all the parameters on CTP when compared to the initial UGIE represented the changes in vasculature before they were endoscopically manifest. CONCLUSIONS: CTP was likely to pick up changes in esophageal and gastric vasculature earlier than UGIE in children with EHO presented with hematemesis.

RESUMO

The authors describe the use of dual-phase intravenous CT angiography of the pelvis in two female patients, who presented with ongoing excessive vaginal bleeding, to demonstrate large adnexal and uterine arteriovenous malformations (AVMs). Power Doppler was used as the initial modality to diagnose the AVMs. CT angiography, along with 3-D rendering in the form of maximum intensity projections and shaded surface display, were especially useful for anatomical conceptualization to the gynecologist. This greatly helped in the subsequent management in the form of therapeutic embolization in both patients by reducing the time, radiation dose, and contrast required for the procedure. Subsequent surgery, which was required in both patients (due to failed embolization), was also greatly aided by the demonstration of the exact extent of the AVMs on axial CT images. Thus, CT angiography emerged as an impressive non-invasive imaging modality for the complete evaluation and management of the uterine AVMs.

RESUMO

Morquio Syndrome (mucopolysaccharidosis type IV A) is a rare inherited connective tissue disorder characterized by skeletal dysplasia, restrictive pulmonary disease and normal intelligence. Tetraplegia secondary to subluxation of C1 over C2 because of odontoid dysplasia is a common occurrence in these patients but there are limited descriptions regarding their specific physiatric management. Two patients (aged 20 and 17 years) were admitted to a pediatric rehabilitation facility after cervical spine stabilization following recurrent tetraplegia (C4 ASIA C and C4 ASIA D). Following surgery, patients were ventilator dependent and aphonic. One patient was successfully weaned off the ventilator to nocturnal BiPAP, while the other was able to tolerate three hours of ventilator free time despite being ventilator dependent for ten years. At discharge, both patients showed significant improvement in mobility, self care skills and communication abilities. Functional independence was encouraged through use of various assistive devices for mobility, activities of daily living (ADL) and communication. Group counseling and peer support were extremely helpful in their adjustment to disability. Physiatric intervention is essential and requires understanding of the unique impairments encountered by tetraplegics with Morquio Syndrome.
