BACKGROUND Maternal zinc deficiency is relatively common in developing countries, but its consequences for fetal growth are not established. OBJECTIVE The goal was to examine whether improvement in maternal gestational zinc status is positively associated with fetal growth as assessed by ultrasonography. DESIGN We conducted a double-masked, randomized trial among 242 pregnant Peruvian women...

Leptohyphes cornutus Allen from Brazil (Santa Catarina) and Misiones, Argentina is re-studied from new material and newly diagnosed as follows: tubercles on head (two pairs), pronotum (two pairs, anterior pair very small), and mesonotum (two pairs), abdominal terga without paired tubercles, nor remnants of them; fore femur length/maximum width, 1.4-1.8; tarsal claws denticulation 4-11+1; hind w...

BACKGROUND The reconstruction of femur defects following tumor resection remains a surgical challenge. The clinical outcome of free vascularized fibula graft (FVFG) reconstruction for massive femur defects of more than 10 cm that were secondary to skeletal tumor resection is reported. PATIENTS AND METHODS Six patients with a mean of 3.3 years follow-up were reviewed. Five patients received do...

OBJECTIVE The purpose of this study was to establish longitudinal reference ranges for fetal ultrasound biometry measurements and growth parameters in twin pregnancies. METHOD A total of 200 uncomplicated twin pregnancies before 21 weeks of gestation were recruited for this prospective, longitudinal study. Women who abandoned follow-up, pregnancies with unknown outcomes or pregnancies with co...

INTRODUCTION Differences in the magnitude of bowing between races are well-known characteristics of the femur. Asian races have an increased magnitude of femoral bowing but most of the orthopedic implants designed for the femur do not match this exaggerated bowing. We calculated the sagittal and coronal femoral bowing in the Japanese population at different levels of the femur and addressed its...

In this study of fractures of the shaft of the tibia and femur in children, the growth rate of these long bones after injury was assessed by serial radiographical measurements of bone length, accurate to the nearest millimetre. Within three months of injury the rate of growth was at its maximum and was 38 per cent in excess of normal. The rate then decreased but remained significantly raised fo...

OBJECTIVE To evaluate the effects of physical training of mother rats during pregnancy associated with a low-protein diet offered during pregnancy and lactation on the development and growth of the femur of their offspring. METHODS Forty 90-day old male Wistar rats were divided into four groups: pups of sedentary nourished mothers, pups of sedentary malnourished mothers, pups of trained nouri...

BACKGROUND Conventional technique of valgus osteotomy of the proximal femur involves removal of a partial or full thickness lateral based wedge from the peritrochanteric region. The purpose of this article is to describe a novel technique of valgus subtrochanteric osteotomy for proximal femur nonunion. METHODS 11 patients with proximal femur nonunions {intracapsular fractures--7, extracapsula...

OBJECTIVE To define the anatomic "safe zone" for placement of external fixator half pins into the anterior and lateral femur. METHODS In 20 fresh-frozen hemipelvis specimens, the femoral nerve and all branches crossing the femur were dissected out to their final muscular locations. The location where the nerves crossed the anterior femur was measured from the anterior superior iliac spine and...

a true estimation of gestational age (ga) plays an important role in quality maternity care and scheduling the labor date. this study aimed to evaluate the normal fetal kidney length (kl) and its correlation with ga. a cross-sectional study on 92 pregnant women between 8th and 10th week of gestation with normal singleton pregnancy underwent standard ultrasound fetal biometry and kidney length m...
