A new Brazilian species of the cricket genus Megalogryllus Chopard (Orthoptera: Gryllidae)

Megalogryllus clamosus, uma nova espécie de grilo do estado de São Paulo, é descrita. As fotografias do holótipo (macho) e do parátipo (fêmea) são apresentadas, assim como o desenho do tégmen direito do macho e a estrutura fálica. As fotografias da pars stridens para mostrar a estrutura dos dentes e o sonograma do canto de chamado do macho são também apresentados.

Avaliação ultrassonográfica do bulbo ocular em cães submetidos à facoemulsificação com ou sem implante de lente intraocular

This study aimed to describe and compare the ultrasonographic alterations in dogs' eyes submitted to facectomy with or without intraocular lens implant (IOL), to assist in the diagnosis of possible alterations related to the surgical procedure and IOL implantation. Nineteen dogs with cataract (21 eyes) were submitted to phacoemulsification and late postoperative evaluation (at five years). The animals were initially submitted to complete ophthalmological exams which preceded the sonogram. Dogs were divided in three groups: (CA) aphakic dogs (n= 11); (PP) pseudophakic dogs with implantation of two IOLs in piggyback (n=5) and (PL) pseudophakic dogs with implantation of a veterinary IOL (n = 5). The ultrasound was carried under the administration of a topic local anesthetic, with a multi frequency linear transducer of 10 MHz. Biometric eye measurements were also performed. The clinical alterations observed were IOL dislocation, retinal detachment, asteroid hyalosis, and vitreous degeneration. Ultrasound examination was an excellent diagnostic tool, as it was possible to confirm and classify these changes. The piggyback implant reduced the measurements between the ciliary body and the vitreous chamber obtained from the ocular biometry when compared to other usual procedures, with no difference between the axial length and the anterior chamber.

Collaboration of ultrasonography in the diagnosis of thyroid gland carcinoma in a dog - case report

The sonographic evaluation of thyroid glands in veterinary medicine presents challenges due to the complexity of the anatomical region, professional experience and type of ultrasonography equipment. The technique is considered a versatile diagnostic method that is noninvasive and has a low cost indicated in different clinical situations. Thyroid carcinoma is a malignant tumor that is often invasive and frequently metastatic to regional lymph nodes and lungs. The prognostic indicators for survival after surgery include tumor size, histological type, mobility and presence or absence of metastasis. The objective of the present report is to demonstrate the importance of ultrasound as a complementary method in the evaluation of thyroid carcinoma in dogs. At the Dr. Halim Atique Veterinary Hospital, an eight-year-old male Pit Bull was examined due to a history of firm painless swelling, approximately six inches in diameter, in the ventral cervical region, for about two months. The sonogram showed a nodular area, with defined and regular margins, and heterogeneous hypoechoic parenchyma, with areas of cavitation and swelling of the thyroid. Histopathology of the nodule was consistent with carcinoma. After thyreoidectomy and hormone replacemet, the patient is in good clinical condition.

Second-trimester soft markers: relation to first-trimester nuchal translucency in unaffected pregnancies

Objective Genetic sonography following first-trimester combined screening appears to increase substantially detection rates for Down syndrome but it relies on the unproved assumption of independence between these tests. In this study we aimed to investigate the relationship between first-trimester nuchal translucency (NT) and a series of second-trimester soft markers and structural defects in unaffected pregnancies. Methods NT measurement in the first trimester was followed by second-trimester scan (18 to 23 + 6 weeks) including examination for three categorical markers (intracardiac echogenic foci, hyperechogenic bowel and structural defects) and measurement of nasal bone length, nuchal-fold thickness, femur length, humerus length, renal pelvis diameter and prenasal thickness. All continuous variables were expressed in multiples of the median (MoM) for gestation and correlation coefficients between log-transformed NT and second-trimester variables were calculated. In addition, frequencies of soft markers and structural defects in cases with increased NT were compared to those with normal NT, using MoM cut-offs. Results In a dataset of 1970 cases, NT was significantly correlated (P < 0.05) with all second-trimester continuous variables, the correlation being strongest for nuchal-fold thickness (r = 0.10). There was a higher frequency of cases with second-trimester nuchal-fold thickness above the 97.5th centile (10.7 vs. 2.2%) and hyperechogenic bowel (2.4 vs. 0.1%) in cases with increased NT. Conclusions Straightforward reassessment of risk using likelihood ratios derived from the second-trimester genetic sonogram might lead to inaccurate estimates. Multivariate models using continuous second-trimester variables might be preferable in sequential screening strategies. Copyright. 2012 ISUOG. Published by John Wiley & Sons, Ltd.

The Portuguese Version of the Placental Paradigm Questionnaire at the Third Trimester of Pregnancy

The purpose of this article is to present the adaptation and factorial validation of the Placental Paradigm Questionnaire (PPQ) for the Portuguese population. Method: The original PPQ was translated into Portuguese (designated as ‘Questionário do Paradigma Placentário’, QPP) and then back-translated into English; the Portuguese and the back-translated versions were evaluated by a panel of experts. The participants were 189 pregnant Portuguese women, interviewed twice while waiting for sonogram examinations. At first, between 20 and 24 weeks of gestation, an Informed Consent was obtained as well as sociodemographic information. Between 28 and 36 weeks of gestation, participants answered the QPP. Results: The principal components analysis showed items to load mainly on two factors: in factor one, loads ranged between .778 and .522, while in factor 2, loads ranged between .658 and .421. Accordingly, two subscales of prenatal maternal orientation to motherhood were considered: (1) Facilitator Factor (α = .815) and Regulator Factor (α = .770). Conclusion: Overall, these data suggest that the Portuguese version of the QPP is a reliable and valid measure for the assessment of prenatal orientation for motherhood. In the future, QPP measurements will allow to relate maternal orientation to motherhood with other variables of psychic organisation in pregnancy and after birth.
