NEWLY RECOGNIZED AUTOSOMAL RECESSIVE FACIOTHORACOSKELETAL SYNDROME

We report on 2 brothers, born to consanguineous parents presenting thin/long face, small ears, blepharophimosis, malar hypoplasia, long neck, pectus excavatum, brachy-camptodactyly, and sacral dimple. We suspect that these patients represent a previously undescribed autosomal recessive syndrome. (C) 1994 Wiley-Liss, Inc.

Electrophoretic and chromatographic profile for S-like hemoglobin

Hemoglobin variants originate mainly by simple amino acid substitutions, the result of nucleotide sequence changes. Recently, the number of known abnormal hemoglobins has increased due to improvement in analysis methodologies; however, many laboratories are not prepared to correctly identify mutants. Hb S is a very well-characterized hemoglobin variant that varies in prevalence in different regions of Brazil. However, there is a type of Hb that presents electrophoretic migration in alkaline pH similar to Hb S, named S-like Hb, which can be incorrectly diagnosed; therefore, its frequency is underestimated. We obtained reference ranges for Hb S by HPLC, and we examined the electrophoretic and chromatographic profiles of S-like Hb. Hb Hasharon, Hb D-Los Angeles, Hb Korle-Bu, Hb Lepore, Hb D-Iran, Hb G-like, Hb Queens, Hb Montgomery, and Hb Q-India were found. Cases of association between two beta chain mutants were also found. Electrophoresis in alkaline and acid pH was utilized to initially screen these Hb variants, and globin chain electrophoresis at both high and low pH was performed to identify the globin chain mutant. Chromatographic analysis permitted the identification of the hemoglobin variant and also facilitated the quantification of these variants. Therefore, an association of classical laboratory diagnostic methodologies is fundamental for the correct identification of suspect Hb variants. The S and S-like hemoglobin profiles determined in this study will help in the diagnosis of these variants in health care services.

Maxillary ulceration resulting from using a rapid maxillary expander in a diabetic patient

One of the characteristics of diabetes mellitus is the exaggerated inflammatory response. The present report shows the reaction from the use of a rapid maxillary expander in a diabetic patient. A 9-year-old child presented an uncommon reaction to the treatment with a rapid maxillary expander, and on follow-up examination, it was discovered that the patient had diabetes mellitus. After controlling the disease, the proposed treatment was used without further incidents. The case calls attention to the presence of uncommon responses to treatment and the need for the orthodontist to suspect a patient's systemic compromise. (Angle Orthod. 2011;81:546-550.)

Perfil de resistência a antimicrobianos de Staphylococcus aureus isolados de granjas e frigoríficos de suínos

Staphylococcus aureus are involved in a wide range of clinical problems to swine industry as son in humans. Epidemiological researchs prove his potential to acquire resistantence to antibiotics. Nowadays, methicillin-resistant S. aureus (MRSA) are responsabilized for nosocomial infections and many studies are done because MRSA are spread to extra hospitalar enrivonment and frequentely isolated from domestic animals including pigs. The aim of this study was to determine the presence o S. aureus at swine farms and identify the mecA, icaA and icaD genes and the resistant proflife to antibiotics. Overal, 458 swabs were taked from five pigeris and two slautherhouses. All the samples were placed on Braid - Parker and blood agar follow by biochemical analyses. The suspect colonies were submitted to PCR to confirm the S. aureus species, by the detection of the coa gene, mecA to avaible meticillin-resistant as son to the virulence gens icaA and icaD that can determine slime production. Antibiogram were done to evaluate the response to 11 antibiotics. All pigeris and slautherhouse were positive and 81 (79%) samples were S. aureus positive including four isolates from pigs employeers. The mecA gene was not detected. The icaD gene was most frequent and 41% were positive to both genes. The antibiogram show a lot of samples penicillin and tetraciclin resistant. Most of the samples were multirestant.

Pilomyxoid astrocytoma of the brainstem

A pilomyxoid astrocytoma is a recently described tumor that occurs predominantly in the hypothalamic-chiasmatic region and is rarely found elsewhere. It has similar features as pilocytic astrocytomas, but has distinct histological characteristics and a poorer prognosis. A pilomyxoid astrocytoma is an aggressive tumor, and increased awareness is necessary with a suspect case. We present the first case of a pilomyxoid astrocytoma of the brainstem described after the newest World Health Organization classification of central nervous system tumors. © F.O.
