Hyperbaric Oxygen as Adjunctive Therapy in Experimental Mediastinitis

BACKGROUND Mediastinitis is a dreaded complication of cardiac surgical procedures. The purpose of our study was to research the role of hyperbaric oxygen therapy (HBO) in the treatment of experimental mediastinitis and to investigate whether it potentiates the antibiotic effects of linezolid, teicoplanin, and vancomycin. METHODS The study included nine groups; an uncontaminated and a contaminated untreated control groups, and seven contaminated groups that received HBO or systemic antibiotics with linezolid, vancomycin, or teicoplanin, or a combination therapy consisting of one of these antibiotics and HBO. There were six adult male Wistar rats in each group. Contaminated groups were inoculated with 0.5 mL 10(8) CFU/mL methicillin resistant Staphylococcus aureus in the mediastinal and in the sternal layers. The antibiotic treatment continued 7 d. Twelve hours later at the end of the treatment, the rats were sacrificed, a sternotomy was performed for each rat and tissue samples from the upper ends of the sternum were aseptically obtained and evaluated microbiologically. RESULTS There was no difference between the therapeutic efficacy of linezolid, teicoplanin, or vancomycin (P>0.05). When the groups were analyzed separately, treatment with a combination of HBO and antibiotic therapy reduced the bacterial count in comparison with HBO or antibiotic treatment alone (P<0.05). The combination of teicoplanin or vancomycin and HBO, respectively, was not more effective in reducing the bacterial count in comparison with the combination of linezolid and HBO (P>0.05). CONCLUSIONS Linezolid and teicoplanin therapy was found as effective as standard vancomycin therapy for methicillin resistant Staphylococcus aureus (MRSA) mediastinitis. Adjunctive HBO offered additional benefit to the antibiotic treatment of mediastinitis.

The Evaluation of 13 Patients with Intrathoracic Extrapulmonary Hydatidosis

Cases of intrathoracic extrapulmonary hydatid cysts are very rare. We identified 13 patients with intrathoracic extra-pulmonary hydatid cysts in our clinic over 12 years. Four patients had extra-pulmonary cysts only; nine patients had both intrapulmonary and extrapulmonary cysts. Cysts were identified in the pleural space, extrapleural region, diaphragm and chest wall. Thoracotomy was used in all patients, and extrapulmonary lesions were removed by cyst extirpation from surrounding tissue or by pericystectomy. In one patient with chest wall involvement, partial rib resections were performed because of rib destruction. In two patients with liver cysts passing through the diaphragm to the thorax, the diaphragm was cut, cysts on the liver roof were removed and then the diaphragm was repaired. There was no mortality, morbidity, or disease recurrence during the post-operative period in any of the 13 patients. We conclude that these rare cases give a new insight into hydatid cyst pathophysiology.

Effects of hyperbaric oxygen therapy on wound healing after tracheal resection and end-to-end anastomoses in rats: results of early observations.

BACKGROUND Proliferating scar tissue is an important problem after tracheal surgery. Hyperbaric oxygen (HBO) provides good support to the poorly perfused tissues. We aimed to evaluate the early effects of HBO therapy on tracheal healing after tracheal resection. METHODS A total of 15 Wistar rats were divided into two groups and two tracheal rings of each rat were resected. A control group received no therapy while the other group was treated with HBO. At the end of the study or when a rat died, a histopathological examination was performed to assess neovascularization, necrosis and epithelization. RESULTS HBO treatment caused better epithelization and inflammation scores compared to the control group. In the HBO group the intraluminal purulent exudates were limited (P=0.001). Healing of the damaged mucosal epithelium was better in the HBO group (P=0.031). In the HBO-treated group, neovascularization also started earlier than in the group without HBO. CONCLUSION Our short-term observation results demonstrate that HBO treatment increases tracheal healing and decreases the complication ratios. HBO may be preferred as a supportive treatment modality during the healing period after tracheal surgery.

A Sledgehammer on the Brachial Plexus: Thoracic Outlet Syndrome, Subclavius Posticus Muscle, and Traction in Aggregate

Reported here is a 30-year-old man who was seen because of pain and weakness in the upper extremities after a tractional injury. Physical examination revealed significant atrophy in the left deltoid and right intrinsic hand muscles, generalized hypoesthesia, decreased deep tendon reflexes bilaterally, and decreased strength in various muscle groups. Roos (right) and hyperabduction (bilateral) tests were positive. Electrodiagnostic studies were consistent with bilateral brachial plexopathy. Cervical radiographs showed long transverse process of C7 on the right side and a small rudimentary rib articulating with C7 on the left side. Brachial plexus magnetic resonance imaging demonstrated an aberrant muscle and compressive brachial plexus injury on the left side. Surgery via transaxillary approach was performed on the left side. The occurrence of traumatic brachial plexopathy in the presence of underlying thoracic outlet syndrome and subclavius posticus muscle is discussed for the first time in the literature.

The influence of specific factors on postoperative morbidity in young adults with bronchiectasis.

BACKGROUND Surgical treatment of bronchiectasis is associated with acceptable mortality and morbidity rates. To date, few reports on the prediction of postoperative morbidity using some preoperative measures have been presented. We present our results regarding the influence of some specific factors on postoperative morbidity on young adult patients who were treated surgically for bronchiectasis. METHODS Between January 2000 and July 2007, 122 patients were operated upon. Female gender, increased number of resected segments, presence of haemoptysis and bilateral disease, compromised pulmonary function test (FEV1/VC<60%) and absence of preoperative fiberoptic bronchoscopy (FOB) were examined as the potential risk factors for postoperative complications such as persistent air leak (PAL), atelectasis, residual air space (RAS), bronchopleural fistula (BPF) and empyaema. RESULTS There was no operative mortality. Morbidity was observed in a total of 16 patients with an overall morbidity rate of 13.1%. Complete resection was achieved in 88 patients (72.1%). The number of resected segments was not found to be significantly associated with increased morbidity. Presence of preoperative haemoptysis did not correlate with postoperative complications significantly. Absence of preoperative FOB was not found to be associated with post-operative complications (p<0.05). Compromised PFT was significantly associated with RAS (p=0.028), however it was not associated with increased risk of PAL, atelectasis or empyaema significantly. CONCLUSION Multi-segmental resectable bronchiectasis should not be considered an occult risk factor for morbidity after resection. Associated non-severe haemoptysis and absence of preoperative bronchoscopy are not associated with significant increased risk of postoperative morbidity.

SPIROMETRIC CHANGES AFTER PLEURAL DECORTICATION IN YOUNG ADULTS

Background:  The collection of pleural fluid and thickened pleura restrict the movement and expansion of lung. The main treatment strategy is lung decortication for the thickened pleura. The aim of this study was to investigate lung functions before and after pleural decortication in young adults.

A novel dissemination pathway of hydatid cyst

Cushing’s syndrome (EAS). Moreover, they suggest that a positive image at Octreoscan is predictive of a successful treatment with somatostatin analogues. We completely agree with the authors about the usefulness of functional images in the follow-up of those patients whose tumour has shown a positive tracer uptake preoperatively. In our experience, among nine patients with EAS, CT helped to localize the lesion in 5/9 cases; Octreoscan was false negative in three, false positive in two, while it early identified two relapses, F-deoxyglucose positron emisson tomography (PET) was false negative in two, false positive in one and positive in one. Furthermore, we also observed that one patient with negative Octreoscan imaging transiently improved his clinical condition when treated with somatostatin analogues. Thus, we believe that every patient with EAS should preoperatively undergo Octreoscan, and probably also PET, but CT or MRI seem to be the best techniques to localize ectopic ACTH tumors. In addition, owing to the relative rarity of this severe condition, it would be hoped and advisable to share experiences and efforts from different Centers.

Is bilateral chylothorax possible after simple cough? Yes

Chylothorax is accumulation of chylous fluid in the pleural space due to impaired integrity of the thoracic duct or its branches. In childhood, the causes differ from those in adults because children less frequently develop malignancies and are more resistant to trauma. Commonly, chylothorax occurs as a complication of tumoral invasion or cardiopulmonary surgery. Treatment of chylothorax is essentially medical. In the event of medical treatment failure or a massive effusion, surgery is needed. We describe the case of a 65-year-old woman who developed bilateral chylothorax after a simple cough. She was treated with a medium-chain triglyceride diet and thoracentesis.

Anterior Mediastinal Angiomyolipoma

Angiomyolipomas are benign, solitary, noninvasive mesenchymal tumors. They most often arise in the kidney. Extrarenal presentations of these tumors are in skin, orophaynx, abdominal wall, gastrointestinal tract, heart, lung, liver, uterus, penis, and spinal cord. Angiomyolipoma of the mediastinum is extremely rare and is composed of an admixture of fat, smooth muscle cells, and tortuous, thick-walled, small to medium sized blood vessels. We present a surgically confirmed case of anterior mediastinal angiomyolipoma incidentally diagnosed in an asymptomatic patient.

Is T3 and T6 Sympathetic Clipping More Effective in Primary Palmoplantar Hyperhydrosis

OBJECTIVE Our aim was to establish a standardized approach for patients with palmoplantar and axillary hyperhidrosis and to compare patient satisfaction and complication rates for two different operations. MATERIALS AND METHODS Between 2008 and 2010, 30 patients underwent conventional T3/4 clipping (group A), and 30 underwent only T3 and T6 clipping (group B). Both groups were compared with regard to compensatory sweating (CS), complications, patient satisfaction and recovery of plantar hyperhidrosis. RESULTS The CS rate was 60 % in group A and 47 % in group B. CS was significantly less in group B compared to group A ( P ≤ 0.001). The plantar hyperhidrosis recovery rate was higher in group B (n = 19) compared to group A (n = 13), but the difference was not statistically significant ( P ≥ 0.299). Patient satisfaction rate was 93.3 % in group A and 96.6 % in group B. CONCLUSIONS Our study showed that T3/6 clipping was as effective as T3/4 clipping for palmar and axillary hyperhidrosis. Our results revealed that this technique is more effective than T3/4 sympathectomy to treat plantar hyperhidrosis.
