“Luck’s always to blame”: silent wounds of a penetrating gunshot trauma sustained 20 years ago

Gunshot tracheal injuries represent life-threatening events and usually necessitate emergent surgical intervention. We report a case of an exceptional finding of a patient with retained ballistic fragments in the soft tissues of the thorax, proximal to the right subclavian artery and the trachea, carrying silently his wounds for two decades without any medical or surgical intervention. The bullet pellet on the upper part of the trachea seen accidentally in the chest computed tomography, was also found during bronchoscopy. In short “luck’s always to blame”

Diffuse Idiopathic Skeletal Hyperostosis (DISH) and non small cell lung cancer: case presentation and review of the literature

Diffuse idiopathic skeletal hyperostosis (DISH), also known as Forestier’s disease, is a systemic non inflammatory disease of unknown cause. It is characterized by the presence of osteophytes due to calcification and ossification of spinal ligaments and entheses. Moreover, diffuse idiopathic skeletal hyperostosis has been associated with a variety of metabolic disorders. However, to the best of our knowledge no association with non small cell lung cancer (NSCLC) has been reported so far. In the present study we report a case of a patient with NSCLC and DISH.Diffuse idiopathic skeletal hyperostosis (DISH), also known as Forestier’s disease, is a systemic non inflammatory disease of unknown cause.

Unilateral hypertransparency on chest radiograph: the congenital Poland Syndrome

  Unilateral hypertransparent hemithorax requires a particular diagnostic approach as it can be the result of diverse pulmonary diseases, including pneumothorax, large pulmonary embolus, unilateral large bullae, mucous plag, airway obstruction and contralateral pleural effusion. Congenital syndromes with chest wall abnormalities, are rare, but often underdiagnosed causes. Poland Syndrome consists of such a rare, congenital anomaly and is characterized by the absence of the pectoralis major muscle and upper limb ipsilateral abnormalities. We present a case of a patient with acute exacerbation of chronic obstructive pulmonary disease (COPD) and a unilateral hypertransparency on chest radiology, attributed to the underlying Poland Syndrome.  

Clinical review: Idiopathic pulmonary fibrosis acute exacerbations - unravelling Ariadne's thread

Idiopathic pulmonary fibrosis (IPF) is a dreadful, chronic, and irreversibly progressive fibrosing disease leading to death in all patients affected, and IPF acute exacerbations constitute the most devastating complication during its clinical course. IPF exacerbations are subacute/acute, clinically significant deteriorations of unidentifiable cause that usually transform the slow and more or less steady disease decline to the unexpected appearance of acute lung injury/acute respiratory distress syndrome (ALI/ARDS) ending in death. The histological picture is that of diffuse alveolar damage (DAD), which is the tissue counterpart of ARDS, upon usual interstitial pneumonia, which is the tissue equivalent of IPF. ALI/ARDS and acute interstitial pneumonia share with IPF exacerbations the tissue damage pattern of DAD. 'Treatment' with high-dose corticosteroids with or without an immunosuppressant proved ineffective and represents the coup de grace for these patients. Provision of excellent supportive care and the search for and treatment of the 'underlying cause' remain the only options. IPF exacerbations require rapid decisions about when and whether to initiate mechanical support. Admission to an intensive care unit (ICU) is a particular clinical and ethical challenge because of the extremely poor outcome. Transplantation in the ICU setting often presents insurmountable difficulties

CD8+ T lymphocytes in bronchoalveolar lavage in idiopathic pulmonary fibrosis

<p>Abstract</p> <p>Background</p> <p>Recently it was shown that in Idiopathic Pulmonary Fibrosis (IPF) tissue infiltrating CD₈₊T lymphocytes (TLs) are associated with breathlessness and physiological indices of disease severity, as well as that CD₈₊TLs recovered by bronchoalveolar lavage (BAL) relate to those infiltrating lung tissue. Since BAL is a far less invasive technique than tissue biopsy to study mechanisms in IPF we further investigated the usefulness offered by this means by studying the relationship between BAL macrophages, neutrophils, eosinophils, CD₃₊, CD₄₊, CD₈₊, CD_8+/38+TLs and CD₄₊/CD₈₊ratio with breathlessness and physiological indices.</p> <p>Patients and methods</p> <p>27 IPF patients, 63 ± 9 years of age were examined. Cell counts were expressed as percentages of total cells and TLs were evaluated by flow cytometry. FEV₁, FVC, TLC, RV, <it>D</it>LCO, PaO₂, and PaCO₂were measured in all. Breathlessness was assessed by the Medical Research Council (MRC) chronic dyspnoea scale.</p> <p>Results</p> <p>CD₈₊TLs correlated positively (r_s= 0.46, p = 0.02), while CD₄₊/CD₈₊ratio negatively (r_s= -0.54, p = 0.006) with the MRC grade. CD₈₊TLs correlated negatively with RV (r_s= -0.50, p = 0.017). CD_8+/38+TLs were negatively related to the FEV₁and FVC (r_s= -0.53, p = 0.03 and r_s= -0.59, p = 0.02, respectively). Neutrophils correlated positively with the MRC grade (r_s= 0.42, p = 0.03), and negatively with the <it>D</it>LCO (r_s= -0.54, p = 0.005), PaO₂(r_s= -0.44, p = 0.03), and PaCO₂(r_s= -0.52, p = 0.01).</p> <p>Conclusion</p> <p>BAL CD₈₊TLs associations with physiological and clinical indices seem to indicate their implication in IPF pathogenesis, confirming our previous tissue study.</p

Jednostronnie jasne płuco na radiogramie klatki piersiowej — wrodzony zespół Polanda

Zwiększenie przejrzystości jednego płuca wymaga wdrożenia szczególnych procedur diagnostycznych, ponieważ przyczyną takiego stanu może być wiele różnorodnych chorób układu oddechowego, włączając odmę opłucnową, masywny zator płucny, duży jednostronny pęcherz rozedmowy, czop śluzowy, zamknięcie dużego oskrzela oraz płyn w przeciwległej jamie opłucnowej. Wrodzone zaburzenia budowy ściany klatki piersiowej należą do rzadkich, choć często niezdiagnozowanych przyczyn. Zespół Polanda należy do takich rzadkich wrodzonych anomalii i polega na niewykształceniu mięśnia piersiowego większego i nieprawidłowościach budowy kończyny górnej po tej samej stronie. W pracy przedstawiono przypadek chorego z zaostrzeniem przewlekłej obturacyjnej choroby płuc (POChP) i obrazem jednostronnie jasnego płuca na radiogramie klatki piersiowej, spowodowanym zespołem Polanda.Zwiększenie przejrzystości jednego płuca wymaga wdrożenia szczególnych procedur diagnostycznych, ponieważ przyczyną takiego stanu może być wiele różnorodnych chorób układu oddechowego, włączając odmę opłucnową, masywny zator płucny, duży jednostronny pęcherz rozedmowy, czop śluzowy, zamknięcie dużego oskrzela oraz płyn w przeciwległej jamie opłucnowej.

MRC chronic Dyspnea Scale: Relationships with cardiopulmonary exercise testing and 6-minute walk test in idiopathic pulmonary fibrosis patients: a prospective study

<p>Abstract</p> <p>Background</p> <p>Exertional dyspnea is the most prominent and disabling feature in idiopathic pulmonary fibrosis (IPF). The Medical Research Chronic (MRC) chronic dyspnea score as well as physiological measurements obtained during cardiopulmonary exercise testing (CPET) and the 6-minute walk test (6MWT) are shown to provide information on the severity and survival of disease.</p> <p>Methods</p> <p>We prospectively recruited IPF patients and examined the relationship between the MRC score and either CPET or 6MWT parameters known to reflect physiologic derangements limiting exercise capacity in IPF patients</p> <p>Results</p> <p>Twenty-five patients with IPF were included in the study. Significant correlations were found between the MRC score and the distance (r = -.781, p < 0.001), the SPO₂at the initiation and the end (r = -.542, p = 0.005 and r = -.713, p < 0.001 respectively) and the desaturation index (r = .634, p = 0.001) for the 6MWT; the MRC score and <it>V</it>O₂peak/kg (r = -.731, p < 0.001), SPO₂at peak exercise (r = -. 682, p < 0.001), VE/VCO₂slope (r = .731, p < 0.001), VE/VCO₂at AT (r = .630, p = 0.002) and the Borg scale at peak exercise (r = .50, p = 0.01) for the CPET. In multiple logistic regression analysis, the only variable independently related to the MRC is the distance walked at the 6MWT.</p> <p>Conclusion</p> <p>In this population of IPF patients a good correlation was found between the MRC chronic dyspnoea score and physiological parameters obtained during maximal and submaximal exercise testing known to reflect ventilatory impairment and exercise limitation as well as disease severity and survival. This finding is described for the first time in the literature in this group of patients as far as we know and could explain why a simple chronic dyspnea score provides reliable prognostic information on IPF.</p

Sjogren&apos;s syndrome

Sjogren’s syndrome (SS) is a chronic, slowly progressive, inflammatory, autoimmune disease characterized by (1) lymphocytic infiltration of the exocrine glands leading to diminished or absent glandular secretion, and (2) marked B-lymphocytic cell hyperreactivity manifested initially by a variety of serum autoantibodies, including those against the Ro(SSA) and La(SSB) ribonucleoproteins, ending in the development of B cell non-Hodgkin’s lymphoma in a substantial number of patients. Most patients with SS present only with keratoconjunctivitis sicca and xerostomia. However, similar to 40% develop extraglandular manifestations that present in two ways: (1) the development of lymphoepithelial lesions in several extra-exocrine gland tissues (i.e., bronchi, renal tubules, or biliary ducts), and (2) vasculitis related to the deposition of immune complexes due to B cell hyper-reactivity. Pulmonary manifestations develop in some patients and may present as (1) bronchitis sicca; (2) a wide spectrum of lymphoproliferative diseases, ranging from bronchus-associated lymphoid tissue (BALT) hyperplasia, lymphoid interstitial pneumonia, and B cell non-Hodgkin’s lymphoma mainly of the extranodal marginal zone B-cell lymphoma of BALT-type or rarely of higher-grade malignancy; and (3) other interstitial pneumonias. Pleuritis can be seen in SS patients with associated systemic lupus erythematosus or rheumatoid arthritis
