Twenty-two elective free-tissue transfers for reconstruction of various defects were performed in 20 pediatric patients over a 7-year period. Patient ages ranged from 5 to 17 years (mean: 12.5 years). There were six open wounds, six unstable scars, five tumor resection defects, three facial gunshot wounds, one facial paralysis, and one penis agenesis. Ten free flaps were transferred to the head and neck region, seven to the lower extremity, four to the upper extremity, and one to the genital area. Ten fasciocutaneous flaps, seven muscle or myocutaneous flaps, and five vascularized bone grafts were transferred. All flaps survived, except for one in an electrical burn patient. The success rate was 95 percent. No vessel spasm was observed. Children tolerated long operation periods better than adults. The recovery time after surgery was considerably shorter than in adults. The mean operative time was 6 hr, and the average hospital stay was 12 days. The mean follow-up period was 27 months. Results of this study indicate that microvascular free-tissue transfer is a safe and reliable method for the reconstruction of various defects in children.
Extracorporeal septoplasty is a radical solution for the severely deviated nose. The major problems associated with this procedure are fixation of the septal cartilage graft and dorsal irregularities. Extracorporeal septoplasty was performed in combination with open rhinoplasty in 17 patients with severe nasal deformities. In this technique septum was totally removed through the columellar incision of open rhinoplasty, corrected outside, and replaced as a free "L" shaped cartilage graft. The cartilage graft was fixated to the upper lateral cartilages to restore the natural relations of the anatomical structures. Additional rhinoplastic manipulations were also performed. The follow-up period was up to 18 months. The overall result was successful in all patients. Nasal deviation did not recur and secondary revisions were not needed for any patient during follow-up.
The present study was aimed at determining in vitro phospholipase and protease activities in 95 clinical isolates of various Candida species (C. albicans, C. glabrata, C. guilliermondii,C.kefyr, C. krusei, C. lipolytica, C. lusitaniae, C. parapsilosis, C.rugosa and C. tropicalis). 59 (62.1%) of isolates examined were phospholipase positive and 75 (78.9.9%) were protease positive. 56 (93.3%) of C.albicans isolates tested were phospholipase producers - however only a few strains of C. glabrata and C. kefyr behaved in the same way. Protease activity was detected in 57 (95%) of C. albicans strains tested and in a few strains of C. kefyr, C.lipolytica, C. parapsilosis and C. tropicalis- the remaining isolates were negative. 56 strains of C.albicans and 2 strains of C. kefyr tested produced both phospholipase and protease.
We report the repeated isolation for Trichoderma.harzianum, a rare opportunistic pathogen from three sets of each of the following clinical samples; blood serum, skin lesions, sputum and throat of a pediatric ALL patient with neutropenia. The definition of invasive fungal infection requires evidence of the presence of fungal elements in tissue samples, in addition to the isolation of suspected etiologic agent in culture. However, invasive procedures are not always applicable due to several factors, as for example in our case, the poor general status of the individual patient or thrombocytopenia. The present paper also emphasizes the problems encountered in obtaining appropriate samples and diagnosing invasive fungal disease in immunocompromised patient populations, including those with hematological malignancy. Three cases involving T. harzianum, including this one, have been described thus far in the literature. All were fatal and the fungus was resistant to antifungal therapy. A critical review of the other two cases of Trichoderma infections in humans is provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
