ABSTRACT

BACKGROUND: Pulmonary infections occasionally present with infectious pseudotumour of the lung not easily distinguishable from true pulmonary neoplasm. In such cases, radiographic findings and clinical manifestation are highly suggestive of lung cancer. These inflammatory lung lesions cause significant diagnostic problems and appropriate therapy is often considerably delayed. We therefore report on our experience with infectious pseudotumour of the lung caused by bacterial, mycobacterial and fungal pulmonary infections. METHODS: In a retrospective case series, patients with lung infections simulating pulmonary carcinoma were identified. Clinical presentation, radiological features, surgical procedures and outcome were analysed. RESULTS: There were seven male and six female patients with a mean age of 53 years. Presumed pulmonary carcinoma and hemoptysis were main reasons for hospital admission. Procedures performed were video-assisted thoracoscopic wedge resection (6), lobectomy (5), video-assisted thoracoscopic lobectomy and open wedge resection each in one case. Pathologic examination of the obtained specimens revealed tuberculoma (5), aspergilloma (3), pulmonary actinomycosis related pseudotumour (3) and coccidioidoma (2). Following definite diagnosis, patients with tuberculosis and fungal infections received antituberculotic and antifungal medications, respectively. Patients suffering from pulmonary actinomycosis received penicillin. There was no in-hospital mortality. One re-thoracotomy was mandatory because of pleural empyema. CONCLUSIONS: Pulmonary infections simulating lung cancer require surgical removal both for establishing definite diagnosis and to manage complications like haemoptysis and ongoing contamination of the airways by infectious agents. Whenever feasible, limited thoracoscopic resections are preferable. Following definite diagnosis antimicrobial drug therapy for a sufficient length of time is mandatory.

ABSTRACT

INTRODUCTION: Parapneumonic pleural empyema is a critical illness. Age is an acknowledged risk factor for both pneumonia and pleural empyema. Furthermore, elderly patients often have severe co-morbidity. In the case of pleural empyema, their clinical condition is likely to deteriorate fast, resulting in life threatening septic disease. To prevent this disastrous situation we adapted early surgical debridement as the primary treatment option even in very elderly patients. This study shows the outcome of surgically managed patients with pleural empyema who are 80 years or older. METHODS: The outcomes of 222 consecutive patients who received surgical therapy for parapneumonic pleural empyema at a German tertiary referral hospital between 2006 and 2010 were reviewed in a retrospective case study. Patients older than 80 years were identified. RESULTS: There were 159 male and 63 female patients. The mean age was 60.5 years and the overall in-hospital mortality rate was 7%. Of the 222 patients, 37 were 80 years or older (range: 80-95 years). The frequencies of predominantly cardiac co-morbidity and high ASA (American Society of Anesthesiologists) grades were significantly higher for very elderly patients (p <0.001). A minimally invasive approach was feasible in 34 cases (92%). Of the 37 patients aged over 80, 36 recovered while one died from severe sepsis (in-hospital mortality 3%). There was no significant difference in mortality between the very elderly and the younger sufferers (p = 0.476). CONCLUSIONS: Early surgical treatment of parapneumonic pleural empyema shows excellent results even in very elderly patients. Despite considerable co-morbidity and often delayed diagnosis, minimally invasive surgery was feasible in 34 patients (92%). The in-hospital mortality of very elderly patients was low. It can therefore be concluded that advanced age is no contraindication for early surgical therapy.

ABSTRACT

OBJECTIVE: To study the value of gastric intramucosal pH and gastric intraluminal PCO2 measurements to predict weaning outcome from mechanical ventilation. DESIGN: Prospective clinical study. SETTING: Intensive care medicine department of a university hospital. PATIENTS: Nineteen adult critically ill patients who were mechanically ventilated because of acute respiratory failure and were considered ready to be weaned. INTERVENTIONS: The patients were weaned with: synchronized intermittent mandatory ventilation plus positive end-expiratory pressure (SIMV+PEEP) or continuous positive airway pressure with pressure support ventilation (CPAP+PSV). A gastric tonometer was placed in all the patients. Tonometric, respiratory, and hemodynamic variables were measured during the weaning process. MEASUREMENTS: Hemodynamic variables, respiratory mechanics, pulmonary gas exchange, respiratory muscle force, spontaneous pattern of breathing, and the central control of breathing were recorded. Simultaneously, the intramucosal pH and gastric intraluminal PCO2 were measured. MAIN RESULTS: Eleven patients were successfully extubated and eight failed. The patients who failed showed higher values of mouth occlusion pressure, respiratory rate, and effective inspiratory impedance (mouth occlusion pressure/mean inspiratory flow). The intramucosal pH was initially 7.19 +/- 0.22 and decreased to 7.10 +/- 0.16 during the weaning process in patients who failed (p < .05). At the same time, the intramucosal pH showed a nonsignificant change from 7.36 +/- 0.07 to 7.32 +/- 0.07 in the patients who were successfully extubated. The intramucosal pH was statistically different when both groups were compared during the initial and the final evaluations (p < .05). For the initial evaluation, the sensitivity and specificity to predict weaning failure when the intramucosal pH was < or =7.30 were 0.88 (95% confidence interval [CI], 0.66-1) and 0.82 (95% CI, 0.59-1), respectively. The gastric intraluminal PCO2 was higher in patients who failed (p < .05). When gastric intraluminal PCO2 was . or =40 torr during the initial evaluation, weaning failure occurred with a sensitivity of 1 (95% CI, 0.31-1) and a specificity of 0.55 (95% CI, 0.26-0.84). CONCLUSIONS: Weaning failure was associated with gastric intramucosal acidosis. The intramucosal pH and gastric intraluminal PCO2 may be helpful to predict weaning outcome. Further controlled clinical trials in a larger group of patients are needed.

ABSTRACT

OBJECTIVE: To determine the presence of tricuspid regurgitation (TR) in patients affected by acute lung injury (ALI) and the adult respiratory distress syndrome (ARDS) during mechanical ventilation with positive end-expiratory pressure (PEEP). DESIGN: A prospective clinical study. SETTING: 10-bed general intensive care unit in a University Hospital. PATIENTS: 7 consecutive patients an age 44.7 +/- 8.6 years with a diagnosis of ALI or ARDS were studied. All were on mechanical ventilation with PEEP. INTERVENTIONS: PEEP was increased in steps of 5 cm H2O until the appearance of TR or up to a limit of 20 cm H2O. MEASUREMENTS AND RESULTS: Right atrial pressure, pulmonary artery pressure, and wedge pressure were measured and cardiac output was determined by thermodilution. TR was graded from 0 to 3. Standard 2D echocardiographic and pulsed-wave images were obtained at each level of PEEP. PEEP was increased from 4 +/- 3 to 17 +/- 2 cm H2O. Mean PAP increased from 27.7 +/- 2.9 to 36.7 +/- 3.5 mm Hg (p < 0.02) when PEEP was increased. Five patients had competent valves and two had mild TR at baseline. In six out of the seven, TR either developed or increased when PEEP was increased. CONCLUSIONS: Our study demonstrated the development of TR after the use of PEEP in patients with ALI and ARDS as a consequence of pulmonary hypertension and right ventricular overloading. Since TR may randomly affect cardiac output values and derived parameters, the assessment of cardiac performance by some techniques such as thermodilution should be used with caution.
