ReviewIs incentive spirometry effective following thoracic surgery?
A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether incentive spirometry is a useful intervention for patients after thoracic surgery. Altogether 255 papers were found using the reported search, of which seven represented the best evidence to answer the clinical question. ⋯ We conclude that incentive spirometry is a relatively good measure of lung function and may be used to assess respiratory recovery in the days after thoracic surgery. Physiotherapy either with or without incentive spirometry reduces the incidence of postoperative complications and improves lung function but there is currently no evidence that incentive spirometry in itself could either replace or significantly augment the work of the physiotherapists. Clinicians should be aware that while incentive spirometry can provide an assessment of lung recovery, well-organised and regular physiotherapy remains the most effective mechanism to augment their patient's recovery and avoid postoperative complications.

ReviewIs it ever worth contemplating an aortic valve replacement on patients with low gradient severe aortic stenosis but poor left ventricular function with no contractile reserve?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether it is worth performing aortic valve replacement in patients with severe aortic stenosis and poor left ventricular function but no contractile reserve on dobutamine stress testing. Altogether 251 papers were identified using the below mentioned search and all major international guidelines were included. ⋯ Thus, absence of contractile reserve on stress testing does not exclude myocardial recovery after surgery, although it is a strong predictor for operative mortality. It should be noted that surgery has only been reported in very few of these patients to date. B-natriuretic peptide has also been suggested as a further marker of better prognosis in these high-risk patients in one small study.

Case ReportsEntirely polytetrafluoroethylene coating for pacemaker system contact dermatitis.
A 63-year-old man underwent pacemaker implantation for complete atrio-ventricular block. The patient repeated admissions for skin necrosis, and generator or pacemaker system was re-implanted each time. The patient was admitted with skin necrosis of the generator pocket three years after re-implantation. ⋯ The patient underwent pacemaker system removal and re-implantation of polytetrafluoroethylene (PTFE) sheets coating pericardium leads and generator. There has been no recurrence. PTFE sheet coating is effective to treat pacemaker system contact dermatitis.

Case ReportsTotal cavo-pulmonary connection without foreign material for asplenic heart associated with partial anomalous pulmonary venous connection.
The presented case was a 3-year-old boy diagnosed with asplenia (SLL), double outlet right ventricle, pulmonary stenosis, atrioventricular septal defect, hypoplastic left ventricle and partial anomalous pulmonary venous connection to the superior vena cava. Partial anomalous pulmonary venous connection was repaired by translocation of pulmonary artery to avoid pulmonary venous obstruction when Glenn anastomosis was performed. Total cavo-pulmonary connection was established by re-routing the inferior vena cava to pulmonary artery using the atrial septal remnant and the left atrium free wall flap.

Clinical TrialDelayed recovery of human leukocyte antigen-DR expression after cardiac surgery with early non-lethal postoperative complications: only an epiphenomenon?
HLA-DR expression on peripheral blood monocytes is reduced after cardiac surgery. Little is known about the reconstitution of HLA-DR expression on peripheral blood monocytes in patients suffering from early non-fatal perioperative complications. We conducted a prospective study to prove whether these complications adversely affect the recovery of HLA-DR expression. ⋯ A delayed recovery of HLA-DR expression is seen in patients with early perioperative complications. These non-fatal complications appear to represent a 'second hit' resulting in a prolonged deficiency of the innate immune system. This might predispose to further infectious and septic complications.
