Frontal fibrosing alopecia development in two patients after botulinum toxin applications: relationship or coincidence?

Frontal fibrous alopecia is a primary lymphocytic scarring alopecia that is difficult to control, with a perifollicular lichenoid infiltrate marking its histology. Since its description in 1994 by Kossard, there has been an increase in cases reported worldwide. This article reports two cases that underwent incisional biopsies with longitudinal and transverse sections in areas presenting higher disease activity and reviews some aspects of this dermatosis. It also addresses the suspicion of a possible relationship with the application of botulinum toxin – a question already raised by other authors but with no established confirmation

Follicular thyroid carcinoma metastatic to skin: a small papule and a big diagnostic change

Made available in DSpace on 2019-09-11T20:58:37Z (GMT). No. of bitstreams: 0 Previous issue date: 2019Abstract: Cutaneous metastases are uncommon in daily practice, although very important, since they may be the first manifestation of an undiscovered primary neoplasm or the first indication of recurrence. Cutaneous metastases from the breast are the most frequent in women and cutaneous metastases from the lung are the most frequent in men. Thyroid carcinoma, despite representing the most frequent endocrine neoplasm, is considered a rare neoplasm, corresponding to 1% of malignant neoplasms diagnosed. Cutaneous metastases from follicular carcinoma are rare and occur mainly in the head and neck area. We report a case of cutaneous metastasis in a patient with follicular thyroid carcinoma and breast carcinoma. Because of the association of these two neoplasms, the possibility of Cowden Syndrome - multiple hamartoma syndrome - was raised, but was excluded by genetic analysis of PTEN gene.[Rocha, Jeanine Alvarenga] Laboratório Bacchi, BrazilLira, Marcia Lanzoni Alvarenga] Laboratório do Vale, BrazilAlmeida, Mariana Abdo de] Universidade de Taubaté, BrazilReis-Feroldi, Michele Maria] Private practice, Brazi

International Nosocomial Infection Control Consortiu (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module

We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care–associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line–associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN
