OBJECTIVES: The relationships between calcaneal bone mass and dietary/lifestyle habits in women at 3-4 months postpartum were examined in the context of osteoporosis prevention. STUDY DESIGN: Cross-sectional survey. METHODS: We measured bone mass using calcaneal ultrasound in mothers who brought their 3- to 4-month-old babies to healthcare centers in Japan for health examination and administered a self-report questionnaire on physical characteristics and dietary/lifestyle habits to those who agreed to participate in the survey...

BACKGROUND: Women who have had hypertension in pregnancy are at greater risk of long term cardiovascular disease (CVD). Little is known about their cardiovascular risk postpartum or the effects on the woman's mental health and the outcomes of their infants. In this project we will study the physiological and psychological health of women and the physical health and development of their infants six months, two years and five years after birth. We will establish normal blood pressure (BP) and metabolic function for women who were normotensive in pregnancy and use these to assess women who had gestational hypertension (GH) or preeclampsia (PE)...

INTRODUCTION: Acute basilar artery occlusion (ABAO) is an infrequent but potentially fatal cause of strokes in both adults and children, and it is usually due to vertebral artery dissection (VAD). VAD has been found to be usually a consequence of traumatic vertebral artery injury. ABAO usually presents with symptoms of acute ischemic stroke (AIS) of the posterior circulation or transient ischemic attack (TIA). It may lead to death or long-term disability if not promptly recanalized. Basilar artery recanalization in children can be achieved safely and with excellent clinical outcome using endovascular thrombectomy with the new generation self-expanding and retrievable stents...

UNLABELLED: Brain stiffness plays an important role in neuronal development and disease, but reported stiffness values vary significantly for different species, for different brains, and even for different regions within the same brain. Despite extensive research throughout the past decade, the mechanistic origin of these stiffness variations remains elusive. Here we show that brain tissue stiffness is correlated to the underlying tissue microstructure and directly proportional to the local myelin content...

Infantile systemic hyalinosis (ISH) (OMIM 228600) is a rare fatal autosomal recessive disorder characterized by extensive deposition of hyaline material in many tissues. Consanguinity has been recorded in many cases. Herein we present two new Saudi cases with review of the literature. Our first proband was a 9 month-old male who was the first baby for parents descended from a closed consanguineous pedigree. The second proband was a 13 month-old male who was the first baby for consanguineous parents (3(rd) C)...

OBJECTIVE: To investigate changes in maternal ECG ST index, blood pressure (BP), cardiac left ventricular (LV) ejection function and vascular tone/stiffness in large and small arteries occurring during elective cesarean section (CS) in spinal anesthesia. MATERIAL AND METHODS: Twenty-six women were monitored with photoplethysmographic digital pulse wave (PW) analysis (DPA) before and after spinal anesthesia, after delivery of the baby, after 5 IU oxytocin bolus IV, and 5 min later...

Cervical softness is a critical parameter in pregnancy. Clinically, preterm birth is associated with premature cervical softening and postdates birth is associated with delayed cervical softening. In practice, the assessment of softness is subjective, based on digital examination. Fortunately, objective, quantitative techniques to assess softness, and other parameters associated with microstructural cervical change are emerging. One of these is shear wave speed (SWS) estimation. In principle, this allows objective characterization of stiffness because waves travel more slowly in softer tissue...

BACKGROUND: In animal studies, iron deficiency during pregnancy has been linked to increased offspring cardiovascular risk. No previous population studies have measured arterial stiffness early in life to examine its association with maternal iron status. OBJECTIVE: This study aimed to examine the association between maternal iron status in early pregnancy with infant brachio-femoral pulse wave velocity (PWV). METHODS: The Baby VIP (Baby's Vascular Health and Iron in Pregnancy) study is a UK-based birth cohort which recruited 362 women after delivery from the Leeds Teaching Hospitals postnatal wards...

Stiff baby syndrome (hyperekplexia) is a rare genetic disorder. The condition can easily be misdiagnosed as epilepsy or severe sepsis because of hypertonicity and seizure-like episodes and has an increased risk of severe apnoea and sudden infant death. Tapping of the nasal bridge inducing a startle response is the clinical hallmark. We report cases of two sisters born with stiff baby syndrome with hypertonicity, exaggerated startle reaction and cyanosis. The syndrome has a good prognosis if treated with clonazepam and both cases were developmental normal after one year...

Hyperekplexia or Stiff Baby Syndrome is an uncommon disorder of non-epileptic movements with an autosomal dominant inheritance pattern. Neonates present exaggerated startle response to sensory stimuli and temporary muscular rigidity. We report two neonates from the northern center of Puerto Rico who presented involuntary movements, hypertonia and apnea during first days of life, being treated with anticonvulsants without improvement. Both were diagnosed with hyperekplexia due to the clinical evolution associated to normal EEG and head radiologic studies...

OBJECTIVE: The neonatal mortality rate (NMR) continues to remain quite high, one important cause being preterm deliveries. The main obstacle in the pathway towards decreasing NMR is identification of babies in need of extra care. To analyze the utility of newborn foot length as a proxy measure for birth weight and gestational age. METHODS: A cross-sectional study done in a hospital of eastern India with 351 babies during 4 months. Right foot length of each recorded using a plastic, stiff ruler...

AIM: To compare the biomechanical properties of a newly proposed technique, utilizing intramedullary nailing and compression bolts, for the osteosynthesis of intra-articular proximal tibial fractures with meta-diaphyseal comminution, with modern and conventional plating techniques. METHODS: Fifteen left tibia 4th generation composite Sawbones models (in 3 groups of 5 for each technique) with identically reproduced type VI Schatzker tibial plateau fractures, including meta-diaphyseal dissociation, were used...

Detecting aberrant fetal growth has long been an important goal of modern obstetrics. Failure to diagnose abnormal fetal growth results in perinatal morbidity or mortality. However, the erroneous diagnosis of abnormal growth may lead to increased maternal anxiety and unnecessary obstetric interventions. We review the aetiology of deviant fetal growth and its implications both for the neonatal period and later in adult life. We examine maternal factors that may influence fetal growth such as obesity, glycaemic control and body composition...

The patient was a 34-year-old woman who, at age 23, was diagnosed with rheumatoid arthritis (RA) presenting with morning stiffness, swelling and tenderness of bilateral knee joints and metacarpophalangeal (MP) joints of the right second and third fingers, increased C-reactive protein (CRP) levels, and a high level of rheumatoid factor (RF). The patient was maintaining remission with oral dose of bucillamine (BUC; 300 mg/day); however, due to the deterioration of arthralgia at age 26, she was additionally administered 8 mg/week of methotrexate (MTX), which improved the symptoms...

OBJECTIVE: To assess the association between maternal arterial stiffness and delivery of a baby that is small for gestational age (SGA) in normotensive pregnant women. STUDY DESIGN: Pulse wave analyses were performed to assess maternal arterial stiffness at 26-33 weeks of gestation in 40 normotensive women who subsequently delivered SGA babies (SGA group) and 111 normotensive women who delivered babies with normal growth (control group). RESULTS: Central systolic pressure (CSP), augmentation index (AIx) and AIx at a heart rate of 75 beats/min (AIx-75) were significantly higher in the SGA group compared with the control group, but this was not the case for brachial systolic pressure, brachial diastolic pressure or brachial pulse pressure...

Osseointegration or osteointegration refers to a direct bone-to-metal interface without interposition of non-bone tissue. The long-term clinical success of bone implants is critically related to wide bone-to-implant direct contact. However, only poor bone formation or even host bone resorption have been shown where bone is in tight contact with the implant surface. It has been suggested that an appropriate space between implant and host bone may be useful for early peri-implant bone formation. Additionally, osseointegration depends on the topographical and chemical characteristics of the implant surface...

A finite element/multi-body model of a newborn infant has been developed by researchers at the University of Windsor. The geometry of this model is derived from a Nita newborn hospital training mannequin. It consists of 17 parts: eight upper and lower limb segments, the torso, head, and a seven-segment neck with seven translational and eight rotational joints. Anthropometry is consistent with hospital growth charts, measurements requested from health professionals and data from the open literature. The biomechanical properties of the model (i...

This article compares two techniques for estimating the parameters describing the motion of a phantom designed to investigate shaking baby syndrome. Parameters of a simple computational model and an impulse response function for a linear second order system were both fitted using kinematic measurements of the motion of an inverted jointed pendulum. From the two methods respectively, the rotational stiffness of the joint was calculated to be 1.396 kgm(2) s(-2) and 1.355 kgm(2) s(-2) and the damping coefficient was calculated to be 0...
