Pelvic girdle

Francisca Leal, Martin J Cohn
Limb reduction and loss are hallmarks of snake evolution. Although advanced snakes are completely limbless, basal and intermediate snakes retain pelvic girdles and small rudiments of the femur. Moreover, legs may have re-emerged in extinct snake lineages [1-5], suggesting that the mechanisms of limb development were not completely lost in snakes. Here we report that hindlimb development arrests in python embryos as a result of mutations that abolish essential transcription factor binding sites in the limb-specific enhancer of Sonic hedgehog (SHH)...

Oral isotretinoin has been in widespread use for more than three decades. It causes numerous side effects; skin and mucous membrane being commonly involved. Musculoskeletal adverse effects are also known to occur, but pelvic girdle myopathy is rarely reported. We report myopathy involving pelvic girdle muscles in a young male who received oral isotretinoin for folliculitis decalvans.

Aetosaurians are some of the most common fossils collected from the Upper Triassic Chinle Formation of Arizona, especially at the Petrified Forest National Park (PEFO). Aetosaurians collected from lower levels of the park include Desmatosuchus spurensis, Paratypothorax, Adamanasuchus eisenhardtae, Calyptosuchus wellesi, and Scutarx deltatylus. Four partial skeletons collected from the park between 2002 and 2009 represent the holotype and referred specimens of Scutarx deltatylus. These specimens include much of the carapace, as well as the vertebral column, and shoulder and pelvic girdles, and a new naming convention proposed for osteoderms descriptions better differentiates portions of the carapace and ventral armor...

BACKGROUND: The ability to maintain static and dynamic balance is a prerequisite for safe walking and for obtaining functional mobility. For this reason, a reliable and valid means of screening for risk of falls is needed. The functional reach test (FRT) is used in many countries, yet it does not provide some kinematic parameters such as shoulder or pelvic girdles translation. The purpose was to analyze video records measuring of distance, velocity, time length, arm direction and girdles translation while doing FRT...

The effects of decomposition microclimate on the distribution of dextromethorphan (DXM) and dextrorphan (DXT) in skeletonized remains of rats acutely exposed to DXM were examined. Animals (n = 10) received DXM (75 mg/kg, i.p.), were euthanized 30 min post-dose and immediately allowed to decompose at either Site A (shaded forest microenvironment on a grass-covered soil substrate) or Site B (rocky substrate exposed to direct sunlight, 600 m from Site A). Ambient temperature and relative humidity were automatically recorded 3 cm above rats at each site...

OBJECTIVE: The Pelvic Girdle Questionnaire (PGQ) is the only condition-specific tool assessing activity limitations and symptoms for those with pelvic girdle pain (PGP). It is simple to administer and can be used in research and clinical settings during pregnancy and postpartum periods; however, there currently is no version for the French-Canadian population. The aim of this study was to translate and culturally adapt the PGQ for the French-Canadian population. METHODS: The French-Canadian translation and adaptation of the PGQ was completed following a 4-stage approach: (1) forward translation, (2) synthesis, (3) expert committee review, and (4) testing of the prefinal version of the questionnaire...

The objective of the present study was to analyze chondrogenesis and the ossification pattern of the limbs of Melanosuchus niger in order to contribute with possible discussions on homology and the fusion pattern of autopodial elements and phylogeny. In the Reserva Extrativista do Lago Cuniã, Rondônia, Brazil, six nests were marked and two eggs removed from each nest at 24-hour intervals until hatching. Embryos were cleared using KOH; bone tissue was stained with alizarin red S and cartilage with Alcian blue...

BACKGROUND: Pelvic girdle pain (PGP) is a multifactorial condition, which can be mentally and physically compromising both during and after pregnancy. However, long-term pregnancy-related PGP has been poorly investigated. This longitudinal follow-up study uniquely aimed to describe prevalence and predictors of PGP and its consequences on women's health and function up to 11 years after pregnancy. METHODS/DESIGN: A postal questionnaire was sent to 530 women who participated in 1 of 3 randomized controlled studies for PGP in pregnancy...

OBJECTIVES: Our primary objective was to describe the prevalence of pelvic floor disorders (PFDs), pelvic girdle pain (PGP), and the female athlete triad (disordered eating, menstrual irregularities, and osteoporosis) in a female triathlete population. We also evaluated for an association between these conditions. METHODS: We administered an online survey to women who self-identified as female triathletes. Using validated questionnaires, Epidemiology of Prolapse and Incontinence Questionnaire and Pelvic Girdle Questionnaire, along with the female athlete triad questionnaire, we identified the prevalence of PFDs, PGP, and female athlete triad in this specific population...

Limestone and marl from Maria Farinha Formation (Paraíba Basin, NE Brazil) accumulated in a shallow continental shelf environment during the expansion of the Atlantic Ocean in early Paleocene (Danian). It contains a rich paleontological record, which comprises many marine invertebrates, several species of bony and cartilaginous fishes, a crocodyliform and turtle remains. Here, we describe a new genus and species of pleurodire turtle from Maria Farinha Formation, based on a nearly complete plastron, an incomplete left pelvic girdle, and four dermal plates of the carapace...

Movements of the pelvic girdle facilitate terrestrial locomotor performance in a wide range of vertebrates by increasing hind limb excursion and stride length. The extent to which pelvic movements contribute to limb excursion in turtles is unclear because the bony shell surrounding the body presents a major obstacle to their visualization. In the Cryptodira, which are one of the two major lineages of turtles, pelvic anatomy indicates the potential for rotation inside the shell. However, in the Pleurodira, the other major suborder, the pelvis shows a derived fusion to the shell, preventing pelvic motion...

Exostoses are the most common benign bone tumors, accounting for 10 to 15% of all bone tumors. They develop at the bone surface by enchondral ossification and stop growing when skeletal maturity has been reached. At first, exostoses are covered by a smooth cartilage cap that progressively ossifies with skeleton maturity. Then they may regress, partly or even completely. Osteochondromas may be solitary or multiple, with the latter associated with hereditary multiple exostoses (HME). Exostoses develop during childhood and become symptomatic during the third decade of life in the case of solitary exostoses, or earlier, in case of HME...

The postcranial anatomy of Crocodyliformes has historically been neglected, as most descriptions are based solely on skulls. Yet, the significance of the postcranium in crocodyliforms evolution is reflected in the great lifestyle diversity exhibited by the group, with members ranging from terrestrial animals to semi-aquatic and fully marine forms. Recently, studies have emphasized the importance of the postcranium. Following this trend, here we present a detailed description of the postcranial elements of Pissarrachampsa sera (Mesoeucrocodylia, Baurusuchidae), from the Adamantina Formation (Bauru Group, Late Cretaceous of Brazil)...

BACKGROUND: The Internet is one of the fastest growing information sources for pregnant women and seems to be used across social and economic strata. However, we still lack knowledge on how interaction in Web-based discussion forums influence maternal health literacy, in terms of how pregnant women access, appraise, and apply information to promote and maintain good health. OBJECTIVE: The aim of this study was to understand how Web-based discussion forums influence maternal health literacy; hence, we explored the role of interactions in Web-based discussion forums among women who experienced health problems during pregnancy...
