- Methicillin-resistant staphylococcus aureus (MRSA) carriage in a dermatology unit(2011) PACHECO, Renata L.; LOBO, Renata D.; OLIVEIRA, Maura S.; FARINA, Elthon F.; SANTOS, Cleide R.; COSTA, Silvia F.; PADOVEZE, Maria Clara; GARCIA, Cilmara P.; TRINDADE, Priscila A.; QUITERIO, Ligia M.; RIVITTI, Evandro A.; MAMIZUKA, Elsa M.; LEVIN, Anna S.OBJECTIVE: The aim of this study was to characterize Staphylococcus aureus (MRSA) carriage in a dermatology unit. METHODS: This was a prospective and descriptive study. Over the course of 26 weeks, surveillance cultures were collected weekly from the anterior nares and skin of all patients hospitalized in a 20-bed dermatology unit of a tertiary-care hospital. Samples from healthcare workers (HCWS) were cultured at the beginning and end of the study. Colonized patients were put under contact precautions, and basic infection control measures were enforced. Staphylococcus aureus colonization pressure was determined monthly. Colonized and non-colonized patients were compared, and isolates were evaluated for antimicrobial susceptibility, SCCmec type, virulence factors, and type. RESULTS: Of the 142 patients evaluated, 64 (45%) were colonized by MRSA (39% hospital acquired; 25% community acquired; 36% indeterminate). Despite isolation precautions, hospital-acquired Staphylococcus aureus occurred in addition to the continuous entry of Staphylococcus aureus from the community. Colonization pressure increased from 13% to 59%, and pemphigus and other bullous diseases were associated with MRSA colonization. Eleven out of 71 HCWs (15%) were Staphylococcus aureus carriers, although only one worker carried a persistent clone. Of the hospital-acquired MRSA cases, 14/28 (50%) were SCCmec type IV (3 PFGE types), 13 were SCCmec type III (46%), and one had an indeterminate type. These types were also present among the community-acquired Staphylococcus aureus isolates. SSCmec type IV isolates were shown to be more susceptible than type III isolates. There were two cases of bloodstream infection, and the pvl and tst virulence genes were absent from all isolates. CONCLUSIONS: Dermatology patients were colonized by community-and hospital-acquired Staphylococcus aureus. Half of the nosocomial Staphylococcus aureus isolates were SCCmec type IV. Despite the identification of colonized patients and the subsequent contact precautions and room placement, Staphylococcus aureus colonization continued to occur, and colonization pressure increased. Pemphigus and other bullous diseases were associated with Staphylococcus aureus.

The aim of this study was to assess the epidemiologic, clinical, and laboratory data of patients admitted to the Dermatology Division of Hospital das Cl ınicas da Faculdade de Medicina da Universidade de São Paulo. We performed a retrospective study of patients admitted to dermatology beds between September 1, 2002, and September 30, 2010. The following variables were analyzed: age, gender, ethnicity, length of stay, dermatologic disease, comorbidities, hospital infection, transfer to the intensive care unit (ICU), and mortality. During this 8-year period, 3308 admissions were analyzed. The most frequent admissions were for infections and infestation (18.0%) andeczema/dermatitis (17.8%). The median length of stay was 13.0 days(SD ± 13). We observed longer admissions for immunobullous disorders (mean, 21.8 days) and chronic ulcers (mean, 20.6 days). Admissions were shorter for benign (mean, 4.0 days) and malignant cutaneous neoplasms (mean, 4.4 days). The mean number of comorbidities per patient was 1.0 (SD ± 1.2) and among the most frequent were hypertension and diabetes mellitus. The rate of hospital infection was 6.2% with the blood stream infection regarded as the most common, and Staphylococcus aureu s as the most infectious agent found in culture. Of the admitted patients, 3.7% were transferred to ICU and 2.5% passed away. In these groups, the most common dermatological diagnosis was immunobullous diseases, and the mean of hospital length stay and hospital infection rate were higher in comparison with the total group of patients. A ward organized and specially intended for the care of patients with dermatologic disease and cutaneous/mucosal manifestations of systemic diseases often provide better medical and nursing care in addition to cost effectiveness. Higher valuation of dermatology inpatient services should be necessary in order to attempt to expand the availability of dermatology beds, mainly in tertiary hospitals, taking into consideration the higher potential of severity of the dermatologic diseases found in many patients referred to this kind of service.bookPart Úlcera por pressão(2017) QUITéRIO, Ligia Maria; MENEZES, Maria Aparecida de Jesus; MOTA, Tatiane Glória da- Inpatient dermatology: profile of patients and characteristics of admissions to a tertiary dermatology inpatient unit in Sao Paulo, Brazil(2014) SAMORANO-LIMA, Luciana de Paula; QUITERIO, Ligia M.; SANCHES JR., Jose A.; NETO, Cyro FestaBackgroundDermatology is primarily an outpatient clinical and surgical specialty, but substantial numbers of patients are admitted to hospital for inpatient treatment in dermatology wards. MethodsWe performed a retrospective study of patients admitted to dermatology beds between September 1, 2002, and September 30, 2010. Patient data were analyzed for age, gender, ethnicity, length of stay (LoS), dermatologic disease, comorbidities, hospital-acquired infection (HAI), transfer to the intensive care unit (ICU), and mortality. ResultsA total of 3308 patients admitted during this 8-year period were identified for analysis. The most frequent admissions were for eczema/dermatitis (17.5%) and cutaneous infections (15.9%). The mean LoS was 13.0days. The meanstandard deviation (SD) number of comorbidities per patient was 1.0 +/- 1.2, among the most frequent of which were hypertension and diabetes mellitus. The rate of HAI was 6.2%; bloodstream infection was regarded as the most commonly acquired type and Staphylococcus aureus as the infectious agent most commonly found in culture. Of the patients admitted, 3.7% were transferred to the ICU and 2.5% died. In these latter two groups, the most common dermatologic diagnoses were immunobullous diseases, and the mean hospital LoS and rate of HAI were higher than in the total admissions cohort. ConclusionsHigher value should be placed on dermatology inpatient services in order to expand the availability of dermatology beds, mainly in tertiary hospitals, in view of the potentially high severity of the dermatologic diseases found in many patients referred to this type of service.
