To drain or not to drain? Predictors of tube thoracostomy insertion and outcomes associated with drainage of traumatic hemothoraces.

INTRODUCTION: Historical data suggests that many traumatic hemothoraces (HTX) can be managed expectantly without tube thoracostomy (TT) drainage. The purpose of this study was to identify predictors of TT, including whether the quantity of pleural blood predicted tube placement, and to evaluate outcomes associated with TT versus expected management (EM) of traumatic HTXs. PATIENTS AND METHODS: A retrospective cohort study of all trauma patients with HTXs and an Injury Severity Score (ISS) ≥12 managed at a level I trauma centre between April 1, 2005 and December 31, 2012 was completed. Mixed-effects models with a subject-specific random intercept were used to identify independent risk factors for TT. Logistic and log-linear regression were used to compute odds ratios (ORs) for mortality and empyema and percent increases in length of hospital and intensive care unit stay between patients managed with TT versus EM, respectively. RESULTS: A total of 635 patients with 749 HTXs were included in the study. Overall, 491 (66%) HTXs were drained while 258 (34%) were managed expectantly. Independent predictors of TT placement included concomitant ipsilateral flail chest [OR 3.03; 95% confidence interval (CI) 1.04-8.80; p=0.04] or pneumothorax (OR 6.19; 95% CI 1.79-21.5; p<0.01) and the size of the HTX (OR per 10cc increase 1.12; 95% CI 1.04-1.21; p<0.01). Although the adjusted odds of mortality were not significantly different between groups (OR 3.99; 95% CI 0.87-18.30; p=0.08), TT was associated with a 47.14% (95% CI, 25.57-69.71%; p<0.01) adjusted increase in hospital length of stay. Empyemas (n=29) only occurred among TT patients. CONCLUSIONS: Expectant management of traumatic HTX was associated with a shorter length of hospital stay, no empyemas, and no increase in mortality. Although EM of smaller HTXs may be safe, these findings must be confirmed by a large multi-centre cohort study and randomized controlled trials before they are used to guide practice.

Pneumothorax-associated fibroblastic lesion in combination with localized pleural angiomatosis: A possible cause of juvenile spontaneous hemopneumothorax.

Spontaneous hemopneumothorax is an uncommon but potentially life-threatening condition, with a potential for a rapid ventilatory collapse and a large collection of hidden blood loss into the pleural cavity. Here, we report the first case in the literature on pneumothorax-associated fibroblastic lesion in combination with localized pleural angiomatosis in a 19-year-old Caucasian male, resulting in massive spontaneous hemopneumothorax and hypovolemic shock. Our findings support a causal link between this condition and pneumothorax. The possible superimposed hemothorax is explainable by the pleural involvement of large angiomatous vessels, prone to rupture.

Traumatic displacement of stomach - a case report.

These days we have fast paced traffic on our roads to help us keep up with our fast paced life. But every boon has a down side and our high velocity traffic is no exception. Here is a case report of a blunt abdominal injury following a road traffic accident. Externally the deceased had only a few grazed abrasions on the forehead and right forearm. But on internal examination of abdomen, it was noticed that the left hemi-diaphragm was torn and the stomach and intestines were found displaced into the left thoracic cavity.

Cattle-caused fatalities in a province of western Turkey: 1996-2010 autopsy results.

Cattle-caused injuries and deaths are much more than predicted. The aim of this research is to determine the prevalence of cattle-caused fatalities and the factors affecting it in a province of western Turkey. The court files on cattle-caused fatalities during a 15-year period between 1996 and 2010 were explored. The proportion of forensic-qualified deaths from the total of 3753 was 0.9% (35/3753). Most of the cases were between the ages of 18 and 65 (60%). Most deaths occurred in the spring and summer months compared with autumn and winter months (9 and 22 vs. 3 and 1, respectively). The mortality rate was much higher in men compared with women (94.3% and 5.7%, respectively). The majority of deaths were caused by injuries on the chest (71.4%). The reason for most deaths was due to hemopneumothorax and lung injury (71.4%). Predicting the behavior of cattle may not always be possible, as such, it is advisable that one wears protective equipment when dealing with cattle.

[A rare cause of hemopneumothorax: an aberrant systemic artery]. / Nadir görülen bir hemopnömotoraks nedeni: Aberan sistemik arter.

Spontaneous hemopneumothorax is a rare situation that can be life-threatening in young patients presenting hemodynamic instability due to hypovolemic shock. One of the extraordinary causes of hemopneumothorax is rupture of an apically located aberrant artery after pneumothorax, which is noticed as a third etiological factor in the literature. This case is presented in order to highlight this uncommon etiological factor together with the literature.

Deer stand fatalities in Kentucky: two cases of reverse suspension and blunt force trauma.

Hunting many types of wild game is an avidly pursued outdoor activity that attracts all ages and both genders at various times of the year. Deer hunting is a popular sport in many regions of North America. A variety of weapons are used in the hunting, trapping, and killing of game. As a variety of different modalities are used, myriad types of injuries unique to the type of hunting can occur. Most deer hunting-related fatalities identified at the Office of the Chief Medical Examiner in Kentucky are accidental firearm injuries. Less commonly encountered are fatalities resulting from elevation of the hunter in a tree stand, often associated with poor design or construction of the perch. We present 2 tree stand-related deaths. One victim died of positional asphyxia due to reverse suspension from a hunting tree stand. The second victim died of multiple blunt force injuries sustained in a 20-foot fall from a tree stand. We summarize the features of morbidity and mortality related to deer hunting based on investigations by the Office of the Chief Medical Examiner.

Dead bodies found in wells.

Corpses found in wells or lime pits must be identified and the cause and manner of death must be determined. There are several circumstances that may lead to the presence of corpses in wells. In this study, 3940 death examinations and autopsies, performed at the Konya Branch of Forensic Medicine Council (Turkey) between 2000 and 2007, were retrospectively investigated, and it was found that 18 (0.46%) of the bodies had been recovered from wells. The cases were evaluated in terms of their demographic features, manner of death (accidental, suicidal, or homicidal), autopsy findings, cause of death, and the characteristics of the wells in which they were found. The ages of the victims ranged from 4 to 74 years, and the average age was 40. 4 +/- 20.6 years. Of total, 16 cases were males and 2 were females. The manner of death was determined to be accidental in 10 of the cases, suicide in 6 of the cases, and homicide in the remaining 2 cases. In 7 of the cases, death had occurred as a result of drowning in water. A comprehensive scene investigation and autopsy must be performed for corpses recovered from wells and pits for both identification and determination of the cause and manner of death. Wells should be covered and kept closed at all times to reduce the number of accidental deaths resulting from falls into wells.

Haemo-pneumothorax and haemoptysis in a patient with suspected Ehlers-Danlos syndrome.

We present a case of recurrent haemo-pneumothorax in a young female patient with previously undiagnosed Ehlers-Danlos syndrome (EDS). The patient presented with a spontaneous haemo-pneumothorax not associated with menstruation. Following further subsequent episodes, left lower lobectomy was performed. In the past, the patient had suffered recurrent atraumatic bilateral patella dislocations which were never fully investigated. Histology of the lung tissue revealed features suggestive of EDS. Haemothorax is a rare complication of type IV EDS. There are very few reported cases of pulmonary presentation of EDS type IV.

The risk factors and management of posttraumatic empyema in trauma patients.

BACKGROUND: Posttraumatic empyema increases patient morbidity, mortality and length of hospital stay, and the cost of treatment. The aim of this study was to identify the risk factors for posttraumatic empyema and to review our treatment outcomes in patients with this condition. METHODS: A total of 2261 patients who were admitted with thoracic traumas and underwent tube thoracostomy between January 1989 and January 2006 were investigated retrospectively. Posttraumatic empyema developed in 71 patients. Logistic regression was used to assess the association between potential risk factors for posttraumatic empyema. All values were expressed as the mean+/-S.D. RESULTS: Eight hundred and thirty-six (37%) of the patients had penetrating type trauma, while 1425 (63%) had blunt type trauma. The rate of posttraumatic empyema development was 3.1% for all patients. Pulmonary contusion was seen in 221 (9.8%) patients and fractures of more than two ribs were seen in 191 (8.4%) patients. Tube thoracostomy placement was performed in the emergency room in 1728 (76.4%) patients, in the hospital ward in 197 (8.7%), in the intensive care unit in 182 (8.0%), and in the operating room in 154 (6.8%). The duration of tube thoracostomy was 6.11+/-2.99 (1-21) days. Retained haemothorax was seen in 175 (7.7%) patients. The mean lengths of hospital and intensive care unit stay were 6.42+/-3.45 and 2.36+/-2.66 days, respectively. The analysis showed that duration of tube thoracostomy (OR, 2.49, p<0.001), length of intensive care unit stay (OR, 4.21, p<0.001), and presence of contusion (OR, 3.06, p<0.001), retained haemothorax (OR, 5.55, p<0.001), and exploratory laparotomy (OR, 2.46, p<0.001) were independent predictors of posttraumatic empyema. The relative risk of posttraumatic empyema was higher than 1 for each of the following risk factors: penetrating trauma (OR, 1.59, p=0.055), associated injuries (OR, 1.12, p=0.628) and fractures of more than two ribs (OR, 1.60, p=0.197). CONCLUSION: Prolonged duration of tube thoracostomy and length of intensive care unit stay, and the presence of contusion, laparotomy and retained haemothorax are independent predictors of posttraumatic empyema. Use of prophylactic antibiotics may be recommended in patients with these risk factors.

Life-threatening endometriosis-related hemopneumothorax.

Catamenial pneumothorax is a relatively rare condition, generally of mild to moderate severity. We report the case of a 29-year-old woman who experienced an episode of life threatening right-sided hemopneumothorax in association with menses. She had already been operated on for recurrent pneumothorax. Treatment of the current episode included urgent tube thoracostomy and iterative thoracotomy, together with lung wedge resection, parietal pleurectomy, and partial diaphragmatic excision. Pathologic examination revealed endometrial implants massively involving the diaphragm, the pleura, and the lung parenchyma. The present report shows that endometriosis-related pneumothorax may be extremely severe. The multiple localizations of endometrial implants in this case may provide a support to the different pathogenic theories of endometriosis-related pneumothorax.

Thoracoscopic findings and surgical management of catamenial hemopneumothorax.

A 43-year-old woman had experienced recurrent right pneumothoraces at the beginning of her menstrual period. Thoracoscopically, multiple small fenestrations were widely found over the tendinous part of the diaphragm. Multiple purple colored nodules were seen on the visceral surface of upper lobe containing intralobar lesions, and about 100 ml blood was pooled in the thoracic space. We performed a video-assisted thoracoscopic resection of the pleural nodule suspected to be the cause of the hemothoraces. Histologically, the resected nodule had intra-alveolar hemorrhage not seen in common endometriosis. Pleurodesis with mechanical abrasion of parietal pleura and the diaphragm was performed. Chemical pleurodesis, with minocycline hydrochloride and distilled water was applied.

Spontaneous hemopneumothorax.

PURPOSE OF REVIEW: Spontaneous hemopneumothorax can be life threatening, and is a cause of patients presenting with unexplained signs of significant hypovolemia. The debate relating to patient selection and timing of surgery in patients with spontaneous hemopneumothorax remains unresolved. RECENT FINDINGS: Our experience together with the latest series published over the last decade on the conservative and surgical management of spontaneous hemopneumothorax are presented and discussed. SUMMARY: Surgery should be performed early in the management of spontaneous hemopneumothorax to reduce morbidity. In particular, video-assisted thoracic surgery, which is associated with potentially fewer post-operative complications and shorter hospital stays compared with thoracotomy, should be considered in patients with spontaneous hemopneumothorax who are hemodynamically stable.

[Post-traumatic bronchial stenosis: a case report]. / Post-travmatik brons stenozu: olgu sunumu.

Bronchial rupture due to tracheobronchial trauma is a very rare condition. Early evaluation is necessary in order to avoid irreversible changes such as fibrosis and bronchial stenosis. Cases with post-traumatic hemo-pneumothorax, pneumomediastinum, subcutaneous emphysema and atelectasis require consideration of bronchial laceration with urgent bronchoscopy and early surgery, if needed. A 15 year-old patient with a history of blunt chest trauma two years ago presented with symptoms of pulmonary infection. Radiological and bronchoscopic evaluation revealed right upper lobe atelectasis secondary to fibrosis. Patient underwent right upper lobectomy.

Sudden death caused by tension pneumothorax after rupture of a thoracic aortic aneurysm. Case report.

A rare case of fatal tension pneumothorax is reported. An aged Japanese man with marked subcutaneous emphysema of the neck was found collapsed in a betting office. He was ascertained to have left tension pneumothorax, based on radiographic examinations carried out before his death. At autopsy, severe pneumomediastinum was observed, and the descending thoracic aorta with a ruptured dissecting aneurysm was closely adhered to the left lung pleura. The hemorrhage spread into the pulmonary parenchyma and finally spouted out from the surface of the lung apex. Because the blood loss itself was not fatal in quantity, it is concluded that the patient died of tension pneumothorax caused by a lung penetration from the rupture of an aortic aneurysm.

Recurrent catamenial hemopneumothorax.

A case of recurrent hemorrhagic catamenial hemopneumothorax resulting from diffuse pleural endometriosis is presented. The pathogenesis of this rare entity is discussed, and the immediate and long-term surgical and medical options for therapy are reviewed.

Pulmonary metastases in patients with low-grade endometrial stromal sarcoma. Clinicopathologic findings with immunohistochemical characterization.

Two cases of low-grade endometrial stromal sarcoma (ESS) presenting as cystic pulmonary metastases are reported. Both lung lesions were initially thought to represent examples of so-called mesenchymal cystic hamartoma. A diligent search of the past medical records in the first case revealed that a primary low-grade ESS of the uterus had been resected 27 years earlier. In the second case, a uterine tumor was seen by computed tomography scan and subsequent pathologic examination of the hysterectomy specimen established the presence of a low-grade ESS. Peritoneal metastases, present in both cases, also presented diagnostic problems until the uterine primaries were recognized. Immunoreactivity for desmin was detected in all primary and metastatic tumor sites examined. We conclude that ESS should be included among the desmin-positive spindle cell sarcomas and that metastatic ESS should be included in the differential diagnosis of "benign" mesenchymal cystic hamartoma of the lung.

Hemopneumothorax in systemic lupus erythematosus.

Neither hemothorax nor pneumothorax are well recognized manifestations of systemic lupus erythematosus (SLE). Two patients with SLE who developed hemopneumothorax during the course of their illness are described. The clinical, laboratory, roentgenographic, and pathological findings are presented. Both patients were treated with chest tube suction, but 1 required surgical decortication of fibrinous pleural adhesions.
