Is age more than manual material handling associated with lumbar vertebral body and disc changes? A cross-sectional multicentre MRI study

Conflicting evidence exists to what extent manual material handling (MMH) causes lumbar disc disease, lack of evidence exist that this effect takes place especially at L5-S1 level, where the greatest moment occurs. The aim was to assess if lumbar vertebral body and disc changes are more common in people whose job involves significant MMH and, if so, to evaluate if lumbar vertebral body and disc changes are more prevalent in the lower part of the lumbar spine (L4-L5 and L5-S1)

Pancreas divisum and duodenal diverticula as two causes of acute or chronic pancreatitis that should not be overlooked: a case report

<p>Abstract</p> <p>Introduction</p> <p>Pancreas divisum is a congenital anatomical anomaly characterized by the lack of fusion of the ventral and dorsal parts of the pancreas during the eighth week of fetal development. This condition is found in 5% to 14% of the general population. In pancreas divisum, the increased incidence of acute and chronic pancreatitis is caused by inadequate drainage of secretions from the body, tail and part of the pancreatic head through an orifice that is too small. The incidence of diverticula in the second part of the duodenum is found in approximately 20% of the population. Compression of the duodenal diverticula at the end of the common bile duct leads to the formation of biliary lithiasis (a principal cause of acute pancreatitis), pain associated with biliary lithiasis owing to compression of the common bile duct (at times with jaundice), and compression of the last part of Wirsung's duct or the hepatopancreatic ampulla (ampulla of Vater) that may lead to both acute and chronic pancreatitis.</p> <p>Case presentation</p> <p>We describe the radiological findings of the case of a 75-year-old man with recurrent acute pancreatitis due to a combination of pancreas divisum and duodenal diverticula.</p> <p>Conclusion</p> <p>Magnetic resonance cholangiopancreatography is advisable in patients with recurrent pancreatitis (both acute and chronic) since it is the most appropriate noninvasive treatment for the study of the pancreatic system (and the eventual presence of pancreas divisum) and the biliary systems (eventual presence of biliary microlithiasis). Moreover, it can lead to the diagnostic suspicion of duodenal diverticula, which can be confirmed through duodenography with X-ray or computed tomography scan with a radio-opaque contrast agent administered orally.</p

Congenital cystic adenomatoid malformation of the lung associated with bronchial atresia involving a different lobe in an adult patient: a case report

<p>Abstract</p> <p>Introduction</p> <p>Congenital cystic adenomatoid malformation of the lung is an uncommon cause of respiratory distress in neonates and babies. The disorder is usually diagnosed in the neonatal period and the first two years of life. This anomaly has been described in association with bronchopulmonary sequestration, extralobar intra-abdominal sequestration or bronchial atresia in live and stillborn babies. It is rarely encountered in adults, in whom the diagnosis is made incidentally from mass lesion features seen on chest radiographs. The oldest patients recorded with this malformation have been about 35 years old, and only 10% of primary diagnoses are made after the first year of life. Delayed diagnosis can be related to infection or serendipitous discovery.</p> <p>Case presentation</p> <p>We describe the radiological findings of a 34-year-old Caucasian woman with a clinical history of recurrent pneumonia, intermittent anterior pleuritic chest pain and haemoptysis. Congenital cystic adenomatoid malformation of the lung associated with bronchial atresia involving a different lobe was discovered.</p> <p>Conclusion</p> <p>Although rare in adults, congenital cystic adenomatoid malformation should be suspected in adult patients who suffer from recurrent or persistent non-productive coughs. The discovery of an association of congenital cystic adenomatoid malformation with bronchial atresia in adulthood is rare but possible, even in different lobes.</p

Pulmonary hypertension and chronic lung disease: where are we headed?

Pulmonary hypertension related to chronic lung disease, mainly represented by COPD and idiopathic pulmonary fibrosis, is associated with a worse outcome when compared with patients only affected by parenchymal lung disease. At present, no therapies are available to reverse or slow down the pathological process of this condition and most of the clinical trials conducted to date have had no clinically significant impact. Nevertheless, the importance of chronic lung diseases is always more widely recognised and, along with its increasing incidence, associated pulmonary hypertension is also expected to be growing in frequency and as a health burden worldwide. Therefore, it is desirable to develop useful and reliable tools to obtain an early diagnosis and to monitor and follow-up this condition, while new insights in the therapeutic approach are explored

Comorbidities in idiopathic pulmonary fibrosis: an underestimated issue

Idiopathic pulmonary fibrosis (IPF) is a progressive and fibrosing lung disease with a poor prognosis. Between 60% and 70% of IPF patients die of IPF; the remaining causes of death may be due to comorbidities occurring in this ageing population. Interest in the role played by comorbidities in IPF has increased in the past few years. The optimal clinical management of IPF is multifaceted and not only involves antifibrotic treatment, but also vaccinations, oxygen supplementation, evaluation of nutritional status as well as psychological support and patient education. Symptom management, pulmonary rehabilitation, palliative care and treatment of comorbidities represent further areas of clinical intervention. This review analyses the major comorbidities observed in IPF, focusing on those that have the greatest impact on mortality and quality of life (QoL). The identification and treatment of comorbidities may help to improve patients' health-related QoL (i.e. sleep apnoea and depression), while some comorbidities (i.e. lung cancer, cardiovascular diseases and pulmonary hypertension) influence survival. It has been outlined that gathering comorbidities data improves the prediction of survival beyond the clinical and physiological parameters of IPF

Prognostic value of mediastinal lymph node enlargement in chronic interstitial lung disease

PURPOSEMediastinal lymph node (MLN) enlargement detected on chest computed tomography (CT) is frequent in patients with interstitial lung disease (ILD) and is shown in approximately 70% of cases of idiopathic pulmonary fibrosis (IPF). We hypothesized that enlarged MLNs might be a predictor of poor prognosis, associated with lower survival and stronger disease severity.METHODSThis study included patients with idiopathic pulmonary fibrosis (IPF) or nonspecific interstitial pneumonia (NSIP) from January 2009 to December 2018. Baseline chest CT scan and one-year follow-up scan of the patients were reviewed for the extent of lung fibrosis and MLNs. Two radiologists independently assessed MLN diameter and location. Patients with drug toxicity-related ILD, sarcoidosis, chronic hypersensitivity pneumonitis and other rare idiopathic interstitial pneumonias were excluded. The primary endpoint was survival. Secondary endpoints included number of hospitalizations for respiratory causes, lung function evaluated by forced vital capacity (FVC) and diffusing capacity for carbon monoxide (DLCO), and lung fibrosis score determined by CT scan.RESULTSWe retrospectively reviewed the medical registries of 110 patients with chronic pulmonary fibrosis (mean age 71 years, 60.4% male). Nine participants were excluded because the CT scans were of poor diagnostic quality for the evaluation of the mediastinum or unavailable for review. The analysis of 101 patients showed that enlarged MLNs (short axis diameter ≥10 mm) were present in 50.5% (n=51) and strongly predicted survival (HR= 2.11, 95% CI 1.12–3.96, p = 0.020). Patients with MLN enlargement experienced greater number of hospitalizations for respiratory causes (mean 2.5 vs. 1.8, p = 0.010) and had significantly worse lung function parameters (FVC, 71% vs. 81%, p = 0.018 and DLCO, 40% vs. 50%, p = 0.001) and a higher lung fibrosis score (50% vs. 39%, p = 0.001).CONCLUSIONIn patients with IPF and NSIP, enlarged MLNs predict survival, are associated with increased number of hospitalizations, and show signs of poorer lung function and more severe fibrosis

The Octopus Sign-A New HRCT Sign in Pulmonary Langerhans Cell Histiocytosis.

Background: Fibrosis in pulmonary Langerhans cell histiocytosis (PLCH) histologically comprises a central scar with septal strands and associated airspace enlargement that produce an octopus-like appearance. The purpose of this study was to identify the octopus sign on high-resolution computed tomography (HRCT) images to determine its frequency and distribution across stages of the disease. Methods: Fifty-seven patients with confirmed PLCH were included. Two experienced chest radiologists assessed disease stages as early, intermediate, or late, as well as the lung parenchyma for nodular, cystic, or fibrotic changes and for the presence of the octopus sign. Statistical analysis included Cohen's kappa for interrater agreement and Fisher's exact test for the frequency of the octopus sign. Results: Interobserver agreement was substantial for the octopus sign (kappa = 0.747). Significant differences in distribution of the octopus sign between stages 2 and 3 were found with more frequent octopus signs in stage 2 and fewer in stage 3. In addition, we only found the octopus sign in cases of nodular und cystic lung disease. Conclusions: The octopus sign in PLCH can be identified not only on histological images, but also on HRCT images. Its radiological presence seems to depend on the stage of PLCH

Incidental finding of bronchial diverticula in a non-smoker population: evaluation on thin-section CT

Bronchial diverticula have been described as a common radiological finding in smoker patients with COPD, but the specificity of this sign should be further investigated. Thus, the aim of our study was to evaluate the prevalence of diverticula in a cohort of non-smoker subjects. Between February and July 2012, 2438 patients were admitted to our Radiology Unit to undergo a chest CT. Among them, we enrolled 121 non-smoking patients (78/121-64.5% females, 43/121-35.5% males), of different age (57.0±20.7 years-range: 12-88), without any respiratory symptoms, submitted to chest CT for several reasons (oncologic evaluation: 59/121-48.8%; follow up of lung nodules: 27/121-22.3%; screening in connectivitis: 12/121-9.9%; others: 23/121-19.0%). We considered thin-section CT scan on axial, coronal and sagittal plans to evaluate prevalence, numbers and level of bronchial diverticula. Diverticula were found in 41/121-33.9% patients, with a slight major prevalence in males (p=0.048), but no significant difference on age. In 31/41-75.6% the number was <3, whereof 17/31-54.8% with just one diverticulum assessed. Regarding the level, in 30/41-73.2% they were subcarinal, but they were also detected in mainstem (2/41-4.9%) and lobar bronchi (with the right upper lobe bronchus most frequently involved- 12/41-29.3%). Bronchial diverticula can be observed in non-smokers, as well as in smoker patients with COPD. However, their prevalence seems to be lower than in smokers and they tend to be isolated and subcarinal. The age of patients does not influence their finding. More studies should be proposed to better define a cut-off between smokers and healthy subjects

Three cases of bone metastases in patients with gastrointestinal stromal tumors

Gastrointestinal stromal tumors (GISTs) are rare, but represent the most common mesenchymal neoplasms of the gastrointestinal tract. Tumor resection is the treatment of choice for localized disease. Tyrosine kinase inhibitors (imatinib, sunitinib) are the standard therapy for metastatic or unresectable GISTs. GISTs usually metastasize to the liver and peritoneum. Bone metastases are uncommon. We describe three cases of bone metastases in patients with advanced GISTs: two women (82 and 54 years of age), and one man (62 years of age). Bones metastases involved the spine, pelvis and ribs in one patient, multiple vertebral bodies and pelvis in one, and the spine and iliac wings in the third case. The lesions presented a lytic pattern in all cases. Two patients presented with multiple bone metastases at the time of initial diagnosis and one patient after seven years during the follow-up period. This report describes the diagnosis and treatment of the lesions and may help clinicians to manage bones metastases in GIST patients
