Fatal Scopulariopsis infection in a lung transplant recipient: lessons of organ procurement.

Seventeen days after double lung transplantation, a 56-year-old patient with idiopathic pulmonary fibrosis developed respiratory distress. Imaging revealed bilateral pulmonary infiltrates with pleural effusions and physical examination demonstrated sternal instability. Broad-spectrum antibacterial and antifungal therapy was initiated and bilateral thoracotomy tubes were placed. Both right and left pleural cultures grew a mold subsequently identified as Scopulariopsis brumptii. The patient underwent pleural irrigation and sternal debridement three times but pleural and wound cultures continued to grow S. brumptii. Despite treatment with five antifungal agents, the patient succumbed to his illness 67 days after transplantation. Autopsy confirmed the presence of markedly invasive fungal disease and pleural rind formation. The patient's organ donor had received bilateral thoracostomy tubes during resuscitation in a wilderness location. There were no visible pleural abnormalities at the time of transplantation. However, the patient's clinical course and the location of the infection, in addition to the lack of similar infection in other organ recipients, strongly suggest that Scopulariopsis was introduced into the pleural space during prehospital placement of thoracostomy tubes. This case of lethal infection transmitted through transplantation highlights the unique risk of using organs from donors who are resuscitated in an outdoor location.

Relationship between patient complaints and surgical complications.

BACKGROUND: Patient complaints are associated with increased malpractice risk but it is unclear if complaints might be associated with medical complications. The purpose of this study was to determine whether an association exists between patient complaints and surgical complications. METHODS: A retrospective analysis of 16,713 surgical admissions was conducted over a 54 month period at a single academic medical center. Surgical complications were identified using administrative data. The primary outcome measure was unsolicited patient complaints. RESULTS: During the study period 0.9% of surgical admissions were associated with a patient complaint. 19% of admissions associated with a patient complaint included a postoperative complication compared with 12.5% of admissions without a patient complaint (p = 0.01). After adjusting for surgical specialty, co-morbid illnesses and length of stay, admissions with complications had an odds ratio of 1.74 (95% confidence interval 1.01 to 2.98) of being associated with a complaint compared with admissions without complications. CONCLUSIONS: Admissions with surgical complications are more likely to be associated with a complaint than surgical admissions without complications. Further research is necessary to determine if patient complaints might serve as markers for poor clinical outcomes.

Laparoscopic adrenalectomy: 100 resections with clinical long-term follow-up.

BACKGROUND: The operative results of 100 laparoscopic adrenal resections in 94 patients and the subsequent impact on postoperative antihypertensive therapy are presented. METHODS: Clinical and follow-up data for resections performed between 1995 and 2003 were obtained from medical records, patient questionnaires, and telephone interviews. RESULTS: The diseases included Conn's syndrome (27 patients), Cushing's syndrome (30 patients), pheochromocytoma (11 patients), and Other tumors (26 patients). Antihypertensive therapy was eliminated or reduced for Conn's syndrome (75%), Cushing's syndrome (27%), pheochromocytoma (88%) and patients with Other tumors (54%). Clinical improvement was observed by 12 months for pheochromocytoma patients as compared with 35 to 45 months for the other groups (p < 0.05). Multivariate analysis showed that pheochromocytoma patients were more likely to experience improvement or cure than the Other tumor group (hazard ratio, 4.87; 95% confidence interval, 1.61-14.7). CONCLUSIONS: Laparoscopic adrenalectomy continues to be safe and efficacious for benign adrenal diseases. Although patients with functional tumors can expect improvement or cure, the time until improvement may be longer than previously recognized.

Management of incidentally discovered cervical paragangliomas: report of two cases and review of current issues.

Paragangliomas of the head and neck are uncommon neoplasms arising from the extra-adrenal paraganglia and include carotid body and glomus vagale tumors. These lesions may be discovered incidentally by imaging studies performed to evaluate carotid atherosclerotic occlusive disease. Incidental paragangliomas of the head and neck may be smaller than those discovered due to symptoms. Although surgical resection remains the definitive treatment for head and neck paragangliomas, important issues of management arise when such lesions are discovered. Two recent cases are reported. Epidemiology, pathophysiology, diagnostic evaluation, and issues of management of head and neck paragangliomas are discussed.

Experimental endocarditis in calf after tricuspid valve replacement.

A calf model for reproducible, prosthetic tricuspid valve endocarditis was developed using Staphylococcus aureus. The course of late prosthetic valve endocarditis was characterized as a fulminant disease when untreated with antibiotics. The earliest sign of a colonized valve prosthesis was an elevation of body temperature, which correlated with occurrence of positive blood cultures. The dose required to colonize an endothelialized tricuspid prosthetic valve in the calf model was 10(7) to 10(8) S. aureus organisms. In the model for late prosthetic valve endocarditis, silver-allantoin-heparin (SAH) treatment of the prosthetic valve gave no protection from inoculums of 10(8) S. aureus injected 60 days after operation. SAH treatment may be beneficial in early stages of prosthetic valve endocarditis, but this requires further study. Simultaneous cultures from the right atrium, the right ventricle, and the aorta of 2 animals showed that there was a 1,000- to 10,000-fold decrease in the bacterial titers across the combined pulmonary and systemic capillary beds. Bacterial titers drawn from the jugular vein had a 46% false negative result, and positive cultures from the external jugular vein showed only 1.3 S. aureus organisms per milliliter of blood. These bacteriological findings point out the risks of depending on sampling from the peripheral venous system when culturing for right heart endocarditis.
