Lung contusion resulting from chest trauma may be present various clinical pictures. It quite often remains unrecognized and is only suspected later when severe complications have developed. Lung contusion may present in association with chest trauma but may also occur alone. It has to be emphasized, that lung contusion as a clinical identity does not necessarily require a blunt or penetrating chest to be in the background. Nowadays, as a result of traffic accidents, following high energy deceleration, lung contusion may present without an actual tissue damage in the chest wall as a condition initiating an independent, life-threatening generalised process. Although lung contusion shows similarities to blast injury of the lung with respect to clinical consequences, other factors play a role in its aetiology and pathology. Its description and recognition as an independent pathology is not simple. Several approaches exist: thoracic trauma, pulmonary contusion, pulmonary laceration, lung contusion; although these may show similar clinical signs, manifest in different pathologies. Pathologies with similar meaning and possibly similar clinical course cannot, actually, be differentiated; they may accompany other injuries to the trunk, skull or extremities, which, alone, are associated with high morbidity and mortality. Generally, it can be declared that besides high energy, blunt injuries affecting the trunk, lung contusion, has been an often neglected additional radiological finding attached to the main report, despite the fact, that its late consequences crucially determine the prospects of the injured.
The liver is the most commonly injured abdominal organ, accounting for around half of abdominal organ injuries. The emergence of liver injury is determined by the injury mechanism, force, and tissue vulnerability. The vulnerability of the liver depends on the strength of the capsule and parenchyma, as well as the weight and dimensions of the liver. The common hepatic diseases, like steatosis, fibrosis, and cirrhosis, can change the organ weight and dimensions, but their exact correlation is not well known. This study was designed to evaluate the correlation between liver diseases, weight, and dimensions. The liver weight, horizontal, vertical, and antero-posterior length were measured obtained by 213 forensic autopsies. The recorded data were compared with body height, age, and liver histology. Body height positively correlated with liver weight (R2 = 0.252), but the correlation was much stronger in the case of livers without structural disease (R2 = 0.450). The liver size seems to significantly decrease with age (R2 = 0.081), but the effect is mostly due to structural alterations that are proven by histology. The comparison of the liver weight in various histological groups clearly indicated that steatosis increases the liver size, but fibrosis does not (if no steatosis is present at the same time). In general, liver dimensions increase proportionally to the liver weight. However, hepatic steatosis causes disproportional enlargement: it does not have a significant effect on the horizontal dimension and has only a minor effect on the vertical dimension. Steatosis affects disproportionally the dimensions with a strange tendency to expand liver anteroposteriorly.
The early hypersensitivity reaction and late bone marrow depression are well-known side-effects of azathioprine, whereas interstitial pneumonia is a rare complication. A 40-year old male patient had been treated with azathioprine in consequence of extensive ulcerative colitis for 10 years. He then complained of 7 d of fever, cough and catarrhal signs, without symptoms of active colitis. Opportunistic infections were ruled out. The chest X-ray, CT and lung biopsy demonstrated the presence of interstitial inflammation. Azathioprine therapy was discontinued as a potential source of the pulmonary infiltrate. In response to steroid therapy, and intensive care, the pulmonary infiltrate gradually decreased within 4 wk. Three months later, his ulcerative colitis relapsed, and ileo-anal pouch surgery was performed. In cases of atypical pneumonia, without a proven infection, azathioprine-associated interstitial pneumonitis may be present, which heals after withdrawal of the drug.
The sharp rise in the frequency of adenocarcinoma and relative decrease of squamous cell carcinoma of the respiratory and digestive systems, raises suspicion of a common element in their carcinogenetic cascade, which could result in similar trends in cell-type distribution changes of esophageal and lung cancers. The possible role of chemical irritation caused by gastroesophageal reflux disease (GERD) in non-small cell lung cancer (NSCLC) patients was investigated. There was no significant difference between the adenocarcinoma and the squamous cell carcinoma groups, neither in the composite DeMeester scores nor in any of the separate parameters of the complex score investigated. However, the ratio of detected gastroesophageal reflux cases was considerably higher than in the average population. This factor may be one element of a multifactorial cancer promotion.
Knowledge on ontogenesis of thoracic surgery is essential not only for understanding present concepts and debates on surgery for tuberculosis, but it also contributes to the further developments in operative treatment of lung cancer. Both diseases have been the leading cause of death in their respective ages. History of tuberculosis follows the classic algorithm: diagnostic, casuistic and therapeutical stages. Villemin followed by Virchow, and, finally, Koch revealed the pathoanatomy and the cause of tuberculosis. The therapeutic phase of lung cancer has been reached without identified cause of the disease. Chest surgery, eradication of the macroscopic focus by physical interference with the involved tissue mass, in both diseases preceded medical treatment. Identification of phenotypes of lung cancer—if it is a single disease at all—does not contravene the concept: the tumor mass should been eliminated. However, causation is not an absolute sine qua non of an effective treatment, as the tuberculosis-lung cancer analogy also proves. Surgical approach of both diseases suffered from the same paraoxon: eradication without direct interference with the causative factor. While lung cancer seems to be controlled by an emerging array of new drugs, tuberculosis poses a new challenge, as multidrug resistant and extensively drug resistant Koch bacteria are emerging and fragile societies’ immunity is weakening. Thoracic surgery has a significant share in the fight against tuberculosis, when drugs and/or society fail. Palliative and radical adjuvant surgery multiplies the chance of cure in those cases, where not much hope is left. The jury is still out in a series of questions, but it is obvious, that surgery is only an option and not a panacea where medicines and their providers fail. Deeper understanding of our past and present failures with tuberculosis and its surgery might contribute to new concepts in coping with lung cancer as well.
