Bacterial and fungal colonization of burn wounds
Macedo, Jefferson Lessa Soares de;Santos, Jo?o Barberino;
Memórias do Instituto Oswaldo Cruz , 2005, DOI: 10.1590/S0074-02762005000500014
Abstract: a prospective study of fungal and bacterial flora of burn wounds was carried out from february 2004 to february 2005 at the burns unit of hospital regional da asa norte, brasília, brazil. during the period of the study, 203 patients were treated at the burns unit. wound swab cultures were assessed at weekly intervals for four weeks. three hundred and fifty four sampling procedures (surface swabs) were performed from the burn wounds. the study revealed that bacterial colonization reached 86.6% within the first week. although the gram-negative organisms, as a group, were more predominant, staphylococcus aureus (28.4%) was the most prevalent organism in the first week. it was however surpassed by pseudomonas aeruginosa form third week onwards. for s. aureus and p. aeruginosa vancomycin and polymyxin were found to be the most effective drugs. most of the isolates showed high level resistance to antimicrobial agents. fungi were found to colonize the burn wound late during the second week postburn, with a peak incidence during the third and fourth weeks. species identification of fungi revealed that candida tropicalis was the most predominant, followed by candida parapsilosis. it is crucial for every burn institution to determine the specific pattern of burn wound microbial colonization, the time-related changes in the dominant flora, and the antimicrobial sensitivity profiles. this would enable early treatment of imminent septic episodes with proper empirical systemic antibiotics, without waiting for culture results, thus improving the overall infection-related morbidity and mortality.
Predictive factors of mortality in burn patients
Macedo, Jefferson Lessa Soares de;Santos, Jo?o Barberino;
Revista do Instituto de Medicina Tropical de S?o Paulo , 2007, DOI: 10.1590/S0036-46652007000600006
Abstract: burn mortality statistics may be misleading unless they account properly for the many factors that can influence outcome. such estimates are useful for patients and others making medical and financial decisions concerning their care. this study aimed to define the clinical, microbiological and laboratorial predictors of mortality with a view to focus on better burn care. data were collected using independent variables, which were analyzed sequentially and cumulatively, employing univariate statistics and a pooled, cross-sectional, multivariate logistic regression to establish which variables better predict the probability of mortality. survivors and non-survivors among burn patients were compared to define the predictive factors of mortality. mortality rate was 5.0%. higher age, larger burn area, presence of fungi in the wound, shorter length of stay and the presence of multi-resistant bacteria in the wound significantly predicted increased mortality. the authors conclude that those patients who are most apt to die are those with age > 50 years, with limited skin donor sites and those with multi-resistant bacteria and fungi in the wound.

Abstract: Um estudo prospectivo, sobre a sensibilidade antimicrobiana da flora bacteriana em úlceras cutaneas leishmanióticas, foi realizado em pacientes portadores de leishmaniose tegumentar, em Corte de Pedra, Bahia. Foram estudados 84 pacientes, principalmente adolescentes e adultos dedicados à lavoura, apresentando les o cutanea única. Staphylococcus aureus predominou (83%) nas culturas, sendo sensível à maioria dos antibióticos testados. Flora bacteriana mista esteve presente na úlcera em 37 (44,1%) pacientes. Entre as bactérias Gram-negativas isoladas, foram mais freqüentes Enterobacter sp (13,1%), Proteus sp (8,3%), Pseudomonas aeruginosa (7,1%) e Klebsiella sp (7,1%), sendo sensíveis principalmente à ciprofloxacina, aminoglicosídeos, cefalosporinas de terceira gera o e carbapenêmicos.

Abstract: a prospective study regarding aspects of antimicrobial susceptibility aspects was realized among patients with tegumentary leishmaniasis in corte de pedra, bahia. cases were composed mainly of adolescent and adult farmer patients with single lesions. staphylococcus aureus predominated (83%) in the culteres with susceptibility to the majority of antibiotics. a mixed bacterial flora in ulcers was encountered in 37 (44,1%) patients. among the gram-negative bacteria isolated, enterobacter sp (13.1%), proteus sp (8.3%), pseudomonas aeruginosa (7.1%) and klebsiella sp (7.1%) were mainly found with susceptibility to ciprofloxacin, aminoglycosides, third generation cephalosporin and carbapenems.

Abstract: background: evaluation of the management of immediate scalp reconstruction after dog bites. methods: there were 55 victims of dog bites on the head seen on the emergency room of the plastic surgery unit, hospital regional da asa norte (hran, brasília, df, brazil) from january, 1999 through december, 2001. results: nine (16.4%) patients had extense injuries on the scalp. from these patients, seven (77.8%) were less than ten years old. the treatment was suture of the lesion of most cases (77,8%). the other cases (22.2%) were treated with graft of the scalp. there was no infection on this series of cases. conclusions: the results indicate that immediate closure of dog bite injuries to the scalp is safe, either by direct suturing or scap grafting.

Abstract: mammalian bite wounds represent a common type of injury usually seen in the emergency room, constituting approximately 1% of visits to emergency departments. the aim of this study was to evaluate the management of the bites injuries to the face presenting to department of plastic surgery, regional hospital of north wing, brasília, brazil, from january to december, 1999. there were 42 patients, with a mean age of 17 years, ranging between 1 and 50 years: 29 (69,0%) patients were males. dog bites were responsible for 71,4% of all bite wounds, following by human bites (26,2%). the mean duration of injury before presentation was 16 hours. the ear was the most common site of injury (40,0%), followed by the lips. surgical treatment consisted of primary closure, either by direct suturing (66,7%), local flap (28,6%) or skin grafting (4,7%). there was no infection in this study. the results indicate that immediate closure of bite injuries is safe, even with older injuries.

Abstract: the foreign body ingestion ocurrs often with children, olds, psychiatrics patients, prisoners or after excessive alcoholic ingestion. most of foreign bodies (80-90%) passes spontaneously, 10 a 20% have to be removed by endoscopy and only one per cent (1%) needs to be removed by surgery. the authors report a case of a 49-year-old woman who swallowed a needle which impacted in cecum. the patient had psychosis maniac-depressive and swallowed the foreign body aiming self-damage. the presence of foreign body in cecum is rare because of physiologic straitments in the gastrointestinal tract. the ingestion of needle corresponds six percent (6%) of swallowed objects aiming self-damage. colonoscopy served for localization the foreign body and its withdrawal with success. colonoscopy for removing foreign bodies is a safe and cheap procedure.

Abstract: objective: to analyze the incidence, characteristics, behavior and mortality rate of patients with self-injury by burns admitted to the burns centre of brasilia, federal district, brazil. methods: the study population consisted of burned patients consecutively admitted to the burns unit of hospital regional da asa norte, brasília, federal district, brazil, during the period from february 2008 to february 2009. data were obtained on admission and were prospectively recorded during hospitalization. patients were followed until discharge or death. results: during the study period, 15 cases were admitted due to self-injury burns in the unit. the mean age was 38.0 ± 20.6 years, 66.7% of cases of self-injury burning were women. in most cases they were married, home providers and poor. the biggest reason was marital conflict. the mortality rate was 40%. the average burned body surface was 38.7 ± 26.1%. alcohol was used by 66.7% of patients to cause the burns. the average duration of treatment was 20.1 ± 14.8 days. self-injury burned patients had more extensive lesions, remained in hospital for longer periods and had worse prognosis. conclusion: patients with self-inflicted burns had a mean higher age, higher burned body surface, longer hospitalization, more infectious complications and higher mortality rate than patients with accidental burns. these patients need constant psychiatric support, which can be helpful in preventing future episodes of self-harm.
