[Role of surgery in Saprochaete capitata (S. capitata) sepsis in a patient with acute myeloid leukemia]. / Rol de la cirugía en el manejo de la infección invasora por Saprochaete capitata.

Saprochaete capitata (S. capitata) fungal sepsis is a severe condition with a clinical presentation that is similar to other yeast originated fungal sepsis. It is observed in patients with hematological malignancies such as acute myeloid leukemia and neutropenia. We report a 23 year old male presenting with cough, fever and malaise. A bone marrow biopsy led to the diagnosis of acute myeloid leukemia. During the first cycle of chemotherapy the patient presented fever: blood cultures were positive for Klebsiella pneumoniae. Despite antimicrobial treatment, fever persisted; a computed tomography showed a focal splenic lesion; a left exudative pleural effusion appeared. A Matrix Assisted Laser Desorption Ionization-Time of Flight mass spectrometry identified the presence of S. capitata. After multiple antifungal treatments and pleural cavity cleansing by means of videothoracoscopy and laparoscopic splenectomy, the infection resolved and the patient completed his chemotherapy.

Secondary free-flap reconstruction following ablation for acute invasive fungal sinusitis.

OBJECTIVE: Acute invasive fungal sinusitis (AIFS) is a frequently fatal infection for which extensive and debilitating surgical debridement is a mainstay of therapy. Resulting defects are often composite in nature, mandating free tissue-transfer reconstruction. Outcomes data for free flap reconstruction are limited. The purpose of this study was to examine surgical outcomes and survival in patients undergoing free flap transfer following invasive fungal sinusitis. STUDY DESIGN: Retrospective case series. METHODS: Between 1995 and 2015, patients undergoing operative debridement for AIFS were identified. Surgical records were used to identify survivors of acute infection who subsequently underwent free flap reconstructive surgery. Patient demographics, cause of immune compromise, defect description, flap type, perioperative complications, indications for revision surgery, functional outcomes, and long-term survival were reviewed. RESULTS: Forty-four patients were treated for AIFS, of those, 30 (68%) survived acute infection. Ten patients underwent maxillectomy, six with orbital exenteration, and were designated candidates for reconstruction. Eight patients underwent reconstruction. Median time from debridement to reconstruction was 67.5 days. Flap types included latissimus dorsi, scapula, anterolateral thigh, rectus, radial forearm, and fibula. Median follow-up was 7.7 months. No perioperative complications were encountered, and all subjects remained disease-free, able to speak and eat normally without prosthetic supplementation. Seven patients (87%) are currently alive. CONCLUSION: Reconstruction of defects left by invasive fungal sinusitis using free-tissue transfer resulted in successful flap survival, with no disease recurrence for all defects and flap types reviewed. Survivors of AIFS are able to tolerate midface reconstruction, with favorable functional outcomes and survival rates. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:815-819, 2017.

Acute fungal sinusitis: natural history and the role of frozen section.

Acute fungal sinusitis is a life-threatening infection affecting immunocompromised patients. Historically, the most commonly recovered fungi are Aspergillus and Mucor. The extent of potentially disfiguring debridement surgery is grossly determined by the appearance of bleeding at the margins, signifying viable tissue and the absence of fungus. Requests for frozen section may concern the initial diagnosis and the intraoperative verification of margin status. In 12 patients with acute fungal sinusitis, frozen section was used in 8. Routine H&E stains demonstrated fungal hyphae in necrotic debris in 5 cases, often associated with vascular and perineural invasion. All patients underwent extensive sinus debridement, including orbital exenteration in 2 cases. All 12 patients died, 9 of fungal sepsis. Autopsy in 3 patients showed pulmonary involvement (2 cases), intracranial spread (1 case), and no residual fungus (1 case). Inexperience with organism recognition is surmountable. Frozen section has a role in the management of this devastating disease.

Vitrectomy for endogenous fungal endophthalmitis.

PURPOSE: The purpose of this study was to evaluate the predisposing risk factors and treatment outcomes of endogenous fungal endophthalmitis (EFE). METHODS: Records of 25 patients (29 eyes), diagnosed with EFE and treated at Shanghai Eye, Ear, Nose & Throat Hospital from January 2002 to December 2006, were retrospectively reviewed. Four patients had bilateral disease. Final visual acuity and recurrence of EFE were evaluated. RESULTS: Of these 25 patients diagnosed with EFE, 20 patients (22 eyes) were treated by pars plana vitrectomy. Of the remaining 5 patients (7 eyes), 3 cases (4 eyes) were cured by antifungal drugs through systemic treatment and intravitreal injection, but another 2 cases (3 eyes) were only given intravitreal injection because of severe general conditions. Of the 22 eyes that underwent pars plana vitrectomy, 16 (73%) eyes gained visual acuity of counting fingers or better. Recurrent EFE was happened in 2 eyes. Vitrectomy was repeated in 1 eye, another was subsequently enucleated due to phthisis. Vitreous culture-proven or smear-proven EFE occurred in 27 or 2 eyes, respectively. Candida albicans occurred in 17 of 29 eyes (59%), and other causative organisms were yeast fungus (3 eyes), Aspergillus niger (3 eyes), Actinomyces (2 eyes),Aspergillus flavus (1 eye), and Fusarium (1 eye). CONCLUSION: Candida albicans were the most common causative organisms in EFE. The most common predisposing risk factors include recent major operation and intravenous administration in rural settings. Most patients with EFE will gain useful vision (counting fingers) after pars plana vitrectomy.

Unusual cause of superior vena cava syndrome diagnosed with transesophageal echocardiography.

PURPOSE: An unusual case of superior vena cava (SVC) syndrome caused by an infected right atrial-SVC junction thrombus may be diagnosed using transesophageal echocardiography. CLINICAL FEATURES: A 59-yr-old male with end-stage renal disease requiring hemodialysis presented with fungemia and later developed facial and bilateral upper extremity edema. Transesophageal echocardiography revealed subtotal occlusion of the SVC at its junction with the right atrium. The mass was surgically removed with cardiopulmonary bypass support. Pathological examination of the mass confirmed the presence of a large fungal colony of Candida species mixed in the thrombus. The patient's signs and symptoms of SVC obstruction resolved, and he was discharged from the hospital four weeks later in stable condition. CONCLUSION: Although usually caused by extrinsic tumour compression, SVC syndrome can result from intravascular caval obstruction. This etiology should also be considered in the differential diagnosis, particularly in patients with intravascular devices. Transesophageal echocardiography is a valuable diagnostic tool in these cases.

Fungal infection in a dissecting aneurysm of the thoracic aorta.

We describe a 54-year-old man who had an ascending aortic prosthetic graft and a porcine aortic valve prosthesis that were infected by Candida albicans. This infection led to the formation of a dissecting false aneurysm of the remaining transverse and entire descending thoracic aorta, and the man was admitted to our hospital for surgical treatment in February of 1991. Staged in situ graft replacement was performed using Borst's "elephant trunk" repair for the proximal aortic reconstruction and an open distal anastomosis technique for the distal repair. Candida albicans in the residual prosthetic graft was identified, and therapy with high-dose liposomal amphotericin B was initiated. The use of liposomal amphotericin B reduces the incidence of adverse effects and allows administration of higher doses than those possible with conventional amphotericin B therapy. Lifelong antifungal therapy is recommended for patients with C. albicans infection of prosthetic aortic grafts.
