Fetal hemoglobin (Hb F) is characteristic of the fetal development period. However, in some genetic conditions, such as hereditary persistence of fetal hemoglobin (HPFH) and delta-beta thalassemia (δβ-thalassemia), Hb F continues to be produced in adulthood. We evaluated the frequency of two mutations of HPFH, HPFH-1 and HPFH-2 African, and two mutations in δβ-thalassemia, Sicilian and Spanish, in a Brazilian population. Peripheral blood samples were collected from adults from hospitals and blood centers in southeast and northeast Brazil. These individuals were healthy and without complaints of anemia, but had increased Hb F. Samples were submitted to electrophoretic and chromatographic analyses to quantify Hb F values and, subsequently, to molecular analyses to verify the mutations. In the molecular analysis, 16 of the 60 samples showed a heterozygous profile for the HPFH mutations, two for HPFH-1 and 14 for HPFH-2. In the same sample set, three were heterozygous for Spanish δβ-thalassemia and none were heterozygous for Sicilian δβ- thalassemia. The Hb F values in the HPFH-2 heterozygotes differed from those previously reported for this mutation. In this group, the HPFH mutations were more frequent than the δβ-thalassemia mutations. The finding of these mutations in this Brazilian population reflects the mixing process that occurred during its formation.

Study design: descriptive, observational, cross-sectional. Purpose: Obesity is a complex, multifactorial disease, including genetic and endocrine factors, demographic, socioeconomic, and epidemiological changes. It affects children, adults, and elderly persons. Searching respective hereditary risk indicators is increasing, mainly by applying simple and low-cost methodology. We included thus dermatoglyphics. Objective: To investigated 30 Brazilian women dermatoglyphic profiles, 46.1 ± 07.87 years old, and body fat % equal or higher than 30%. Results: Arch predominance, low loop frequency, and high amount of IV-finger whorls were observed, as well as frequency of rare palmar pattern in 2-interdigital area. Conclusions: Data confirm the variability of dermatoglyphics frequency in different population groups, revealing that the findings meant obesity, regardless of women's different personal characteristics. Thus, additional evidences on constitutional component of obesity have been accumulated.

The updating of the of the prolapse of the third eyelid gland treatment in the literature is pertinent, due to the different surgical techniques for his resolution, with advantages and disadvantages. The work aimed to report the Moore technique in surgical treatment of the bilateral prolapse of the third eyelid gland in a female dog with bilateral entropion, six months, Shar-Pei breed, attended in the Veterinary Hospital School, Mozambique. The Moore technique showed good results and if the bilateral entropion was not a spastic type, was able to do the both surgeries in same day. The surgery using the Moore technique continues easy to learn, more simple to do and does not affect the third eyelid mobility.

Purpose: The article aims to introduce nurses to how genetics-genomics is currently integrated into cancer care from prevention to treatment and influencing oncology nursing practice. Organizing Construct: An overview of genetics-genomics is described as it relates to cancer etiology, hereditary cancer syndromes, epigenetics factors, and management of care considerations. Methods: Peer-reviewed literature and expert professional guidelines were reviewed to address concepts of genetics-genomics in cancer care. Findings: Cancer is now known to be heterogeneous at the molecular level, with genetic and genomic factors underlying the etiology of all cancers. Understanding how these factors contribute to the development and treatment of both sporadic and hereditary cancers is important in cancer risk assessment, prevention, diagnosis, treatment, and long-term management and surveillance. Conclusions: Rapidly developing advances in genetics-genomics are changing all aspects of cancer care, with implications for nursing practice. Clinical Relevance: Nurses can educate cancer patients and their families about genetic-genomic advances and advocate for use of evidence-based genetic-genomic practice guidelines to reduce cancer risk and improve outcomes in cancer management. © 2013 Sigma Theta Tau International.

Hereditary or acquired cerebellar hypoplasia (CH) is commonly diagnosed in Holstein, Guernsey, Shorthorn and Jersey cattle. Bovine viral diarrhea (BVD) has been associated to acquired CH due to viral infection during the second trimester of pregnancy. Stricken calf usually shows ataxia, hypermetria, opisthotonus, intentional tremor and wide-based stance when in standing position. Three newborn calves were referred to the FCAV/Unesp Veterinary Teaching Hospital because of neurological distress. The clinical presentation, similar in all cases, indicated CH. Two weeks later, clinical signs did not improve and euthanasia was performed. Macroscopic examination revealed a gelatinous serosanguineous fluid over the brain surface and within the cervical spinal canal. Histologically the cerebellum had disorganization of the internal granular layer and moderate disappearance of Purkinje cells. The observed clinical signs and nervous tissue lesions were consistent with congenital cerebellar syndrome, possibly associated to viral infection during fetal development. Despite CH has been assumed to be related to BVD, blue tongue and Akabane viruses, only the BVD etiology has been already identified in Brazil.

Condylar hyperplasia is an overdevelopment of the condyle, which may manifest unilaterally or bilaterally. This pathological condition can lead to facial asymmetry, malocclusion, and dysfunction of the temporomandibular joint. The etiology and pathogenesis of condylar hyperplasia remain uncertain, but it has been suggested that its etiology may be associated with hormonal factors, trauma, and hereditary hypervascularity, affecting both genders. The diagnosis is made by clinical examination, and radiological imaging, and additionally, bone scintigraphy, is a fundamental resource for determining whether the affected condyle shows active growth. Patients with active condylar hyperplasia management have better results when they are subjected to the high condylectomy procedure. The authors report a case in a 20-year-old female subject with unilateral active condylar hyperplasia who was treated by high condylectomy. The patient has been followed up for 4 years without signs of recurrence and with good functional stability of the occlusion. © 2013 by Mutaz B. Habal, MD.

Purpose: Sleep bruxism is common among the various oromotor alterations found in individuals with cerebral palsy (CP). Few studies have investigated the use of the mastication device denominated hyperbola (HB) and none was found describing the use of such a device for the treatment of bruxism in children with CP. The aim of the present study was to evaluate the effect of the HB on electromyographic (EMG) activity in the jaw-closing muscles and the reduction in sleep bruxism in a child with CP using surface EMG analysis before and after nine months of treatment. Methods: A seven-year-old boy with severe spastic CP and sleep bruxism was enrolled in this study. The HB was chosen as the treatment option for sleep bruxism in this case because the child did not accept an occlusal splint. The HB has a hyperbolic shape and is made of soft, non-toxic, odorless, tasteless silicone. There are five different sizes of HB manufactured based on the diversity of tooth sizes. This device produces proprioceptive excitation in the dentoalveolar nerve, spindles and Golgi tendon organs. HB has been employed for the treatment of temporomandibular disorder, abnormal oro-dental development, abnormal occlusion, xerostomy, halitosis and bruxism. HB therapy was performed for 5 min six times a day over a nine-week period. Surface EMG of the mandible at rest and during maximum contraction was performed on the masseter and temporalis muscles bilaterally to evaluate electromyographic activity before and after nine months of HB usage. Results: HB usage led to a visible tendency toward the reorganization of mastication dynamics, achieving a marked balance in electromyographic activity of the jaw-closing muscles and improving the child's quality of life. Conclusion: Based on the findings of the present study, this noninvasive therapy may be useful for individuals with cerebral palsy due to its positive effects and low cost, which allows its use in the public health realm. Further clinical studies with a larger sample size are needed to validate these results and allow the development of a new treatment protocol for patients with spastic cerebral palsy. © 2013 Elsevier Ltd.
