Long-term results of GH therapy in GH-deficient children treated before 1 year of age. (1/225)

OBJECTIVES: To evaluate the long-term effects of GH therapy in early diagnosed GH-deficient patients treated before 1 year of age. STUDY DESIGN: We studied all 59 patients (33 males) recorded by Association France-Hypophyse and treated with GH (0.50+/-0.15 IU/kg (S.D.) per week) before 1 year of age. Clinical presentation and growth parameters under GH treatment were analyzed. RESULTS: Neonatal manifestations of hypopituitarism were frequent: hypoglycemia (n=50), jaundice (n=25) and micropenis (n=17/33). Although birth length was moderately reduced (-0.9+/-1.4), growth retardation at diagnosis (5.8+/-3.8 months) was severe (-3.5+/-1.9 standard deviation scores (SDS)). Fifty patients (85%) had thyrotropin and/or corticotropin deficiency. After a mean duration of GH therapy of 8.0+/-3.6 years, change in height SDS was +3.11+/-2.06 S.D., exceeding 4 SDS in 19 patients. Only 9 patients (15%) did not reach a height of -2 S.D. for chronological age and 20 patients (34%) exceeded their target height. Pretreatment height SDS was independently associated with total catch-up growth. CONCLUSION: Conventional doses of GH allow normalization of height in patients with early GH deficiency and treatment.  (+info)

Growth hormone treatment in young children with Down's syndrome: effects on growth and psychomotor development. (2/225)

BACKGROUND: Learning disability and short stature are cardinal signs of Down's syndrome. Insulin-like growth factor I (IGF-I), regulated by growth hormone (GH) from about 6 months of age, may be involved in brain development. AIMS: To study long term effects of GH on linear growth and psychomotor development in young children with Down's syndrome. Study design-Fifteen children with Down's syndrome were treated with GH for three years from the age of 6 to 9 months (mean, 7.4). Linear growth, psychomotor development, skeletal maturation, serum concentrations of IGF-I and its binding proteins (BPs), and cerebrospinal fluid (CSF) concentrations of IGF-II were studied. RESULTS: The mean height of the study group increased from -1.8 to -0.8 SDS (Swedish standard) during treatment, whereas that of a Down's syndrome control group fell from -1.7 to -2.2 SDS. Growth velocity declined after treatment stopped. Head growth did not accelerate during treatment. No significant difference in mental or gross motor development was found. The low concentrations of serum IGF-I and IGFBP-3 became normal during GH treatment. CONCLUSIONS: GH treatment results in normal growth velocity in Down's syndrome but does not affect head circumference or mental or gross motor development. Growth velocity declines after treatment stops.  (+info)

Growth in Sotos syndrome. (3/225)

Although there are several reports on infant and childhood growth in patients with Sotos syndrome, there is little information on the final height achieved and puberty. Growth data on 40 patients (20 female and 20 male) aged 2-31 years were collected. These showed that patients with Sotos syndrome are excessively tall at birth, during infancy, and during childhood. Disproportionately long limbs constitute much of the increase in stature. However, the combination of advanced bone age and early onset of menarche led to a mean (SD) final height of 172.9 (5.7) cm in women. This is within the normal range for the population. Most of the men also attained a final height (mean, 184.3 cm; SD, 6.0) within the normal range, although exceptions were more likely in men than in women. Therefore, these results show that most patients with Sotos syndrome do not require intervention to limit their adult height.  (+info)

Estrogen supplementation for bone dematuration in young epileptic man treated with anticonvulsant therapy; a case report. (4/225)

We encountered a young man treated with anticonvulsant therapy who had greatly reduced bone mineral density. An 18-year-old man was admitted to our hospital for shoulder pain and further evaluation of decreased bone mineral density. He had been treated with anticonvulsants, including phenytoin, phenobarbital, valproic acid and zonisamide for seizures. Although testosterone was found within the normal range for adult men, the serum estrogen concentration was below the detection limit (< 10 pg/ml) and his wrist epiphyses were not yet closed. After 10 months of treatment with the conjugated estrogen, both his height and weight showed improvement, while his bone mineral density and bone age were increased. These findings suggested that estrogen therapy had a significant effect on his skeletal growth and bone maturation in man. This is the first report showing the beneficial effect of estrogen supplementation in an epileptic man receiving treatment with anticonvulsants.  (+info)

Bone age assessment: a large scale comparison of the Greulich and Pyle, and Tanner and Whitehouse (TW2) methods. (5/225)

PURPOSE: Comparison of bone age assessed using either the "atlas matching" method of Greulich and Pyle or the "point scoring system" of Tanner and Whitehouse (TW2). MATERIALS AND METHODS: 362 consecutive "bone age" radiographs of the left hand and distal radius performed in a large provincial teaching hospital. Data were analysed using the "method comparison" statistical technique. Ten per cent of the radiographs were re-analysed to assess intra-observer variation. RESULTS: The 95% confidence interval for the difference between the two methods was 2.28 to -1.52 years. Intra-observer variation was greater for the Greulich and Pyle method than for the TW2 method (95% confidence limit, -2.46 to 2.18 v -1.41 to 1.43). CONCLUSION: The two methods of bone age assessment as used in clinical practice do not give equivalent estimates of bone age and we suggest that one method only (preferably the TW2) should be used when performing serial measurements on an individual patient.  (+info)

Skeletal maturity in Pakistani children. (6/225)

Skeletal maturity in 750 normal Pakistani children (400 males, 350 females) aged 1-18 y was determined by the Greulich-Pyle atlas system. Male children during first year and female children during first 2 y of life matured in conformity with Greulich-Pyle standards. After that period mean bone ages were lower than the American standards up to 15 y in males and 13 y in females (at or around puberty), which may be due to malnutrition, ill health or other environmental factors. After puberty bone ages were higher than the American standards indicating earlier maturity in Pakistani than Western children. Hence for the proper evaluation of skeletal age in a given region, a longitudinal study on individuals in that region to establish normal standards is necessary.  (+info)

The potential of digital dental radiography in recording the adductor sesamoid and the MP3 stages. (7/225)

The current study was undertaken to evaluate the reliability of using a recent advance in clinical radiographic technique, digital dental radiography, in recording two growth indicators: the adductor sesamoid and MP3 stages. With an exposure time five times less than that used in the conventional approach, this method shows greatest flexibility in providing a high quality digitized radiographic images of the two growth indicators under investigation.

Determination of age at death using combined morphology and histology of the femur. (8/225)

Bone is characterised by age-related morphological and histological changes. We have previously established an automated method of recording bone morphometry and histology from entire transverse sections of cortical bone. Our aim was to determine whether data acquired using this automated system were useful in the prediction of age. Ninety-six specimens of human femoral middiaphysis were studied from subjects aged 21-92 y. Equations predicting specimen age were constructed using macroscopic data (total subperiosteal area (TSPA), periosteal perimeter (PP), endosteal perimeter (EP), cortical bone area (CA) and moments of area) and microscopic data (the number, size and diversity of pores and intracortical porosity) together with sex, height and weight. Both TSPA and PP were independent predictors of age but the number of pores was not a significant predictor of age in any equation. The age predicted by these equations was inaccurate by more than 8 y in over half the subjects. We conclude that we could not predict age at a clinically acceptable level using data from our automated system. This most likely reflects an insensitivity to regional age-related changes in bone histology because we recorded data from each entire cortex. Automated bone measurement according to cortical region might be more useful in the prediction of age. The inclusion of TSPA together with PP as independent predictors of age raises the possibility that a future measure of periosteal shape at the femoral diaphysis could also be helpful in the prediction of age. The accuracy reached with the relatively simple methods described here is sufficient to encourage the development of image-analysis systems for the automatic detection of more complex features.  (+info)

Whelton, H.J.; Power, S.B., 1993: The use of badger bacula as a method of age determination in a badger population infected with tuberculosis
This study presents unique longitudinal data on skeletal maturation in adolescents from a middle-income country. Moreover, the study provides mean growth curves for RUS bone scores which permit the analysis of sex and ethnic differences in patterns of skeletal maturation. The results show that black boys mature later than white boys whereas black as well as white girls mature at the same age. A longitudinal analysis clarifies how this pattern emerges; skeletal maturation in black girls starts to accelerate later than in white girls, but develops faster, whereas in black boys, skeletal maturation starts to accelerate later and then develops at a similar rate.. The differing patterns of skeletal maturity in the two ethnic groups by sex are intriguing. In all populations, girls are more skeletally mature than boys from birth onwards and reach adult bone maturity, on average, 2 years earlier than boys (1.9 years here).2 Similarly, lower socioeconomic status is generally associated with delayed bone ...
Bone age is the degree of maturation of a childs bones. As a person grows from fetal life through childhood, puberty, and finishes growth as a young adult, the bones of the skeleton change in size and shape. These changes can be seen by x-ray. The "bone age" of a child is the average age at which children reach this stage of bone maturation. A childs current height and bone age can be used to predict adult height. For most people, their bone age is the same as their biological age but for some individuals, their bone age is a couple years older or younger. Those with advanced bone ages typically hit a growth spurt early on but stop growing early sooner while those with delayed bone ages hit their growth spurt later than normal. Kids who are below average height do not necessarily have a delayed bone age; in fact their bone age could actually be advanced which if left untreated, will stunt their growth. At birth, only the metaphyses of the "long bones" are present. The long bones are those that ...

A simple and rapid method has been developed for the direct determination of the age (i.e. the prodution date) of uranium-containing nuclear materials by inductively coupled plasma mass spectrometry based on the measurement of the 230 Th/234 U radionuclide ratio. The concentration of the trace-level 230 Th in the samples was measured directly without the need of prior chemical separation. the tailing of the highly abundant 238 U peak, which is tipically around 10 orders of magnitude higher that that of the 230 Th signal, was eliminated by the matematical deconvolution of the measured mass spectrum. The 230 Th and 234 U contents were quantified by isotope dilution method. thje developed method was validated using reference materials of known production date ...

Bone age assessment, a crucial part of the diagnosis and management of pediatric growth disorders as well as the timing of certain pediatric orthopedic procedures, has for decades depended on the meticulous examination of plain radiographs.
Background: Both the Tanner-Whitehouse-III RUS score, which is based on the radiographic appearance of the epiphyses of the distal part of the radius, the distal part of the ulna, and small bones of the hand, and the digital skeletal age skeletal maturity scoring system, which is based on just the metacarpals and phalanges, correlate highly with the curve acceleration phase in girls with idiopathic scoliosis. However, these systems require an atlas and access to the scoring system, making their use impractical in a busy clinical setting. We sought to develop a simplified system that would correlate highly with scoliosis behavior but that would also be rapid and reliable for clinical practice. Methods: A simplified staging system involving the use of the Tanner-Whitehouse-III descriptors was developed. It was tested for intraobserver and interobserver reliability by six individuals on thirty skeletal age radiographs. The system was compared with the timing of the curve acceleration phase in a ...

Epigenetic clocks comprise a set of CpG sites whose DNA methylation levels measure subject age. These clocks are acknowledged as a highly accurate molecular correlate of chronological age in humans and other vertebrates. Also, extensive research is aimed at their potential to quantify biological aging rates and test longevity or rejuvenating interventions. Here, we discuss key challenges to understand clock mechanisms and biomarker utility. This requires dissecting the drivers and regulators of age-related changes in single-cell, tissue- and disease-specific models, as well as exploring other epigenomic marks, longitudinal and diverse population studies, and non-human models. We also highlight important ethical issues in forensic age determination and predicting the trajectory of biological aging in an individual.

By request from Bane NORs maintenance department, registration of vegetation was done on selected stations along four railway lanes during the summer of 2016. These four lanes were chosen because they are situated in different climate zones and have stations with plantings of varying size and complexity. The registrations included species identification, vegetation dimensioning, age determination, ground location and ground cover materials, weed growth, bush coverage, pests and damage, vitality, and need for maintenance measures. On the 23 stations, a total of 295 trees and area of 2491 m2 covered by shrub were registered. Of the 295 trees there were 31 tree species, 29 species and 2 cultivars. Of the 2491 m2 of shrub field there were 40 shrubs, 26 species and 14 cultivars. The use of vegetation was relatively little varied, and two birch species accounted for almost 30% of all tree species. There was greater variation in the use of bushes, but the largest variation was distributed on a few of ...

85% of Sr reacting with N2O and >70% Sr reacting with SF6; Rb does not react with either gas. As a result, the sensitivity for Sr reaction products is ∼10 times higher with N2O and ∼8 times higher with SF6 compared to O2. With these more reactive gases, the error of mica isochron ages, calibrated against a newly developed nano-particulate pressed powder tablet of mica-Mg, is ∼1% using a 50 μm laser spot. Our tests show that both N2O and SF6 form interfering reaction products, e.g., SrOH (N2O), SiF3 and TiF3 (SF6) that are difficult to handle using single mass spectrometer instruments, but which can be overcome using MS/MS. Using SF6 combined with H2, it is possible to measure 40Ca+ as 40Ca19F+, free from interference of 40Ar+ and 40K+. This facilitates the dating of micas by the K-Ca isotopic system; we present the first in situ K-Ca age determination. ...

Bottom line: if you are one of those who equates "starting" with "riding", then I guess you better not start your horse until hes four. That would be the old, traditional, worldwide view: introduce the horse to equipment (all kinds of equipment and situations) when hes two, crawl on and off of him at three, saddle him to begin riding him and teaching him to guide at four, start teaching him maneuvers or the basics of whatever job hes going to do - cavalletti or stops or something beyond trailing cattle - at five, and hes on the payroll at six. The old Spanish way of bitting reflected this also, because the horses teeth arent mature (the tushes havent come in, nor all of the permanent cheek teeth either) until hes six.= This is what Id do if it were my own horse.

The temporary teeth are in part erupted at birth, and all the incisors are erupted in twenty days; the first, second and third pairs of temporary molars are erupted in thirty days; the teeth have grown large enough to touch each other by the sixth month. Temporary incisors or "milk" teeth are smaller than the permanent incisors. Cattle have thirty-two teeth, including six incisors or biting teeth and two canines in the front on the bottom jaw. The canine teeth are not pointed but look like incisors. The incisor teeth meet with the thick hard dental pad of the upper jaw. Cattle have six premolars and six molars on both top and bottom jaws for a total of twenty-four molars. The teeth of cattle are designed primarily for grinding, and they use their rough tongues to grasp grass and then nip it off between their incisors and the dental pad.[1] There is controversy on the ...
Most commonly, premature thelarche is diagnosed in a female infant or a girl up to three years of age. Occasionally, a girl from three to six years of age will show an enlargement of one or both breasts. However, after age six, the beginning of breast development is actually the beginning of puberty; however, it is a very slow form of development. In addition, girls with early breast development usually do not have early periods.. Typically, the girl has no other signs of puberty, and is growing at a normal, pre-pubertal growth rate, i.e., about two inches a year. Laboratory studies are not usually helpful, since they show low (pre-pubertal) concentrations of estrogen or other hormones that stimulate pubertal development. An x-ray of the hand shows a picture that is normal for the girls age, and not that of an older girl.. top. ...

M orphological changes of the articular surfaces of the innominate provides an excellent postcranial age indicators for adult remains. Variation in the face of the pubic symphysis, the anterior-most point of articulation between the two innominates in the pelvic girdle, is a common region analyzed for age determination. Todd (1920) outlined a 10-stage method for assessing this surface, based on a large sample of male innominates. Changes in the symphyseal surface over time proceed in a predictable pattern from a heavily contoured face, to one delimited by a rim in the mid 30s, to a surface marked by increasing porosity after 40 years. Analysis by Meindl and coworkers (1985) has shown the Todd method to be the most accurate of the pubic symphyseal methods available. It should be noted however, that a tendency to over-age individuals has been found after age 40 by some (BROOKS, 1955), while others claim under-aging of the 45+ year old individuals is problematic (Aiello and Molleson, 1993 ...

Dear Guys, During the last several years i detected unknown truth talking about Lithuanian boulders- the Carboniferous and Permian marine rocks are very numerous and their age is various- there can be found almost each stage of Carboniferous and Permian. The main rock types are three- dolomite and limestone with masses of brachiopods that is various in color, stromatolite limestone with mollusks and unidentified cephalon like fossils, and the last- lacustrine limestone with coelacanth scales and possible plant remains (Carboniferous rhabdodermatids are very numerous). Carboniferous period and Early- Middle Permian was not known in Lithuanian glacial boulders so I very need the strong expert, especially who works on Carboniferous- Permian brachiopods. If my age determinations are correct then I will write the scientific book about this discovery and i think there is huge possibility that many of these boulders could be transported by someone glaciation from Northwestern Russia (or Northern Ural) ...

In order to establish the unidentified genetic cause of IGHD, WES was performed. Briefly, we aligned sequence reads to the 1000 Genomes Phase 1 reference mapped to GRCh37 using BWA v0.5.9 (10) and removed duplicate read pairs using PICARD v1.74. We performed realignment, recalibration and variant calling using GATK v3.3 (11) and applied GATK VQSR filter (12) to remove low-quality variants. Variant annotation was retrieved by using ANNOVAR (13) revealing a homozygous c.431C,T, p.Leu144His mutation in GHRHR. This mutation is indeed detected in the homozygous state by Sanger sequencing, but it was originally overlooked by the first Sanger sequencing, patient 5 of reference (7). This alteration was not seen when the sequencing data were initially read but after the WES it could be found in the original Sanger sequencing. Here we report the correct GHRHR findings for this patient. This mutation has been previously described in unrelated patients with IGHD from Sergipe/Brazil, Pakistan, Spain and the ...
