Samenvatting (Summary, in Dutch) 163 Algemene Conclusie In dit proefschrift hebben we verschillende aspecten van de menselijke groei, waaron der de etiologie, verwijzing, diagnostisch onderzoek, behandeling en de kwaliteit van het leven, besproken en onderzocht. Er is een volgende een stap gezet in het vergroten van de kennis van groeistoornissen en behandelstrategieen en er zijn suggesties gege ven voor toekomstig onderzoek. Gezien de grote variatie aan vormen van groeicurves en de vele mogelijke onderlig gende aandoeningen die een verstoorde groei kunnen veroorzaken, lijkt het nastreven van een ideale combinatie van criteria voor groeimonitoring misschien niet haalbaar. We erkennen en benadrukken het belang van groeimonitoring in de jeugdgezond heidszorg en kindergeneeskunde. We zouden willen aanbevelen om daarbij the focussen op elk van de drie hoofdprincipes voor groei (lengte, afstand tot ‘target height’ en een groeiafbuiging) met behulp van de huidige evidence-based richtlijnen, en daarbij de Finse en de Nederlandse richtlijnen als leidraad the gebruiken, in combinatie met een goede medische anamnese en volledig lichamelijk onderzoek. De medische professie heeft richtlijnen die gebaseerd zijn op gedegen en betrouwbaar onderzoek nodig, maar een arts mag nooit stoppen voor zichzelf the denken: richtlijnen zijn gemaakt om richting the geven, maar de meest waardevolle leidraad voor een indivi duele medische beoordeling is het kind zelf. Toekomstig onderzoek zou zich, volgens ons, daarom minder moeten richten op het nastreven van ideale criteria en meer op het nut van het verrichten van aanvullend onderzoek bij kinderen die verwezen worden met een vermoedelijke groeistoornis, maar zonder aanwijzingen voor een specifeke diagnose. Gezien de, in het algemeen, beperkte kennis van genetische afwijkingen bij jeugd en kinderartsen en de ondergeschikte rol van de klinisch geneticus in dit diagnostische proces, willen we het belang van genetische diagnostiek en haar snelle ontwikkelingen benadrukken. Misschien zal de arts op een dag in staat zijn om elk kind met een ver stoord groeipatroon een ‘whole genome sequence’ aan the bieden, evenals ‘genoom-wijd epigenetisch’ onderzoek. Echter, men zal hierbij altijd met een kritische blik moeten 9 kijken naar de ethische kwesties die hiermee gepaard gaan. In dit hele diagnostische proces moet de medische professie er zorg voor dra gen dat ernstige stoornissen en aandoeningen, die behandeling behoeven, opgespoord worden. Maar tegelijkertijd pleiten we ervoor dat men probeert niet elk klein of lang kind the medicaliseren of stigmatiseren. Want hoe zou onze wereld eruitzien als iedereen 164 Samenvatting (Summary, in Dutch) dezelfde lengte zou hebben, dezelfde oogkleur of dezelfde gezichtsvorm Wij zijn van mening dat deze variatie, binnen bepaalde grenzen, ieder mens uniek en interessant maakt. Door dit the accepteren en the waarderen en deze opvatting door the geven aan de volgende generatie, kan de kwaliteit van leven van kinderen met niet-pathogene kleine of lange gestalte worden verbeterd zonder de tussenkomst van groeihormoonbehande ling of chirurgische remming van de groei.

Best luck for your brand new lab, and remember to tell me when “parallelly” finally goes into the Oxford Dictionary! Shanti, thanks for your magic at Delta, and I will remember which is the Joke of the Year 2006! Wendy, for your wonderful wax sections and being so efficient in keeping up my deadlines. Dad, I still remember those days when you keep pressing those little buttons on your calculator to work out how much money we need for me to do this PhD. Mopo, thanks for paying my credit card bills when I went for holidays and all those peppers I found in my flat after you left. Martin and Carol, lab life at Mill Hill is much better with you guys around, good luck to both of you scientists! Friends outside research in London, especially Patty and Karen, I feel secure knowing you girls will be here when I need you. Thanks to the Heavenly Father, without You, I will never be at this position today. These begin with a cell fate decision, whether to make Sertoli or follicle cells, that gives rise to the development of a male or female gonad, which is controlled by the testis-determining gene Sry. Following the expression of Sry, genes involved in the male pathway act to reinforce and maintain testis-specific cell fate decisions, as well as to repress the female pathway.
Hydrops represents a poor prog nostic sign because it is associated with a decrease in Bradycardias medicine 751 cheap 250 mg chloromycetin visa. Multiple blocked atrial ectopics represent a of long-term postnatal antiarrhythmic therapy [80] medicine number lookup buy chloromycetin online now. In the nonhydropic fetus medicine used to stop contractions order 250mg chloromycetin with mastercard, the frst-line treatment is transplacen tal digoxin treatment 0f gout cheap chloromycetin 500mg without prescription, followed, if conversion to sinus rhythm is not achieved within seven to ten days, by association with fecainide or sotalol. Only in refractory cases should direct fetal drug administration or delivery be considered. In the hydropic fetus, monotherapy with digoxin is likely to be ineffective due to impaired transplacental transfer. As for the nonhydropic fetus, direct administration of the drug in the fetal circulation or delivery is considered only in cases of failed conversion. It is classifed into three associated with the production of anti-Ro or anti-La degrees. On the reconstructed M-mode strip from a 4D volume data set, the atrial rate is 161 bpm (in yellow, lower right end corner of the image, measurement 1), while the ventricular rate is 83 bpm (in yellow, lower right end corner of the image, measurement 1). The mechanism through which conduction system and the myocardium through anti-Ro antibodies seem to damage primarily (but not anti-infammatory agents, such as steroids; and (2) uniquely) the fetal conduction system is the following. Regarding the former aspect, both the anti-Ro antibodies, with consequent impairment dexamethasone and betamethasone have been used; of the physiological apoptosis, attraction of macro robust data in favor of such long-term treatment are phages, and production of cytokines. Infammation, not available, but concerns about fetal and mater fbrosis, and calcifcation in the conducting system nal side effects of steroid therapy have been raised. Such treatment is indicated if the heart factors indicating a relatively high risk of perinatal rate falls below 55 bpm and/or in cases of impaired death include fetal hydrops, endocardial fbroelas cardiac contractility. In these cases, both drugs—if tosis, and ventricular escape rates less than 55 bpm. Along these lines, an early view, assessment of the cardiac situs and its relation echocardiography (at 14–16 gestational weeks) has been with the fetal stomach should be carried out.

Its upper borders anatomy is the classic four-chamber view of the fetal are represented by the clavicles and the neck; it is lim heart. In fact, in this plane, most thoracic viscera can ited inferiorly by the diaphragm, laterally by the ribs, be displayed, including the ribs, the sternum, and the and anteriorly by the sternum. This is why numerous scientific soci blades can be seen in strict relationship with the ribs eties refer to the four-chamber view as the key view and the clavicles. However, if the results organs can be identifed: the lungs, which extend from from this view are abnormal, and a thoracic lesion is the diaphragm to the upper border, just below the clav found, this should be explored further using coronal icles; the heart, which is located in the lower medias and sagittal views, as reported below. The midsagittal tinum and lies on the surface of the diaphragm; and and parasagittal views allow display of the diaphragm the mediastinum, with the great vessels and the thy as a hypoechoic layer below the basal aspects of the mus, larger in the fetus than in the neonate. The bony lungs and the heart, and above the liver and the stom outline, represented by the rib cage, and the overlying ach. The diaphragm shows a curved outline, convex soft tissues complete the thoracic area. With regard to the other anatomic normal and abnormal anatomy of thoracic viscera are districts, because the anatomic scan is usually carried described. The heart and the great vessels are described out (in most countries), at 18–22 weeks of gestation, all in Chapter 5. After this period, the increased mineraliza already mentioned, this represents the fundamental tion of the ribs leads to significant acoustic shadowing, plane where heart and lung anatomy is assessed. On which limits the display of intrathoracic organs, espe this view, the following structures can and should be cially if coronal or sagittal views are sought (see below).
In general symptoms 3dpo discount chloromycetin 250mg line, cardiomegaly is a sign of cardiac overload treatment of schizophrenia buy 500 mg chloromycetin overnight delivery, which may or may not evolve Prognostic indicators pretreatment order chloromycetin paypal. The cause of the of the cardiomegaly and the presence or absence of cardiomegaly can be cardiac or extracardiac symptoms 7 days after embryo transfer cheap chloromycetin 500mg on-line. If, on the contrary, the pathogenesis of the cardiomegaly is insufficient emp hydrops is associated with other nontreatable condi tying of cardiac chambers due to the venous engorgement tions, then the prognosis is generally very poor. Cardiomyopathies inducing myocardial dysfunction (pump failure) and/or congenital heart diseases associated with severe atrio ventricular valve insufficiency may be responsible for the development of cardiomegaly (see Chapter 5). Premature constriction/closure of the ductus arteriosus, both spon taneous and induced by cyclooxygenase inhibitors such as indomethacin and nimesulide [43], is another rare but serious cause of cardiomegaly and heart failure. Except for very severe cases of cardiomegaly, such as those characterizing the worst cases of Ebstein’s anomaly (Chapter 5), it is necessary to quantify the degree of cardiac enlargement by measuring the car diothoracic ratio: this is the ratio between the cardiac circumference (or area) and the thoracic circumference Figure 6. Note the the cardiothoracic ratio is similarly elevated, but due to discrepant biometry between the donor (D) and recipient (R) a decrease in the denominator (Figure 6. The latter had already developed ascites as a sign of to assess whether it is the heart that is enlarged or the high-output cardiac failure. This includes antiarrhythmic therapy for tachyarrhythmias and intrauterine blood transfu sions for parvovirus B19 infections. With regard to the former, the first-line drug is digoxin, which can be administered by a transplacental route (oral maternal Figure 6. The cardiotho therapy) or, in highly hydropic fetuses, by direct intra racic ratio can be abnormal due to cardiomegaly or thoracic venous fetal therapy (umbilical vein). It the main feeding vessels of the tumor; the results are depends on the cause of the cardiomegaly. As already mentioned, good survival can be achieved in cases Obstetric management. Should cardiomegaly be benefiting from intrauterine therapy (antiarrhythmic detected, fetal echocardiography should be carried transplacental or direct therapy for tachyarrhythmias; out to confirm or rule out the existence of congenital intrauterine blood transfusions for parvovirus B19 heart disease or cardiomyopathy as the primary cause infections; and placental laser treatment of arteriove of the cardiomegaly.

The occurrence of thymic hypo to an abnormal development of the third and fourth plasia may also be derived by calculation of the thy branchial arches which, in turn, depends on the absent mic-thoracic ratio, which provides an accurate estimate migration of neural crest cells toward these embryo of the thymic versus thoracic volumes [49].

There are, however, few practitioners who have not been challenged at least once by a newborn with ambiguous genitalia or by a young woman with primary amenorrhea on a genetic basis. The categorization of the various syndromes in this area has been confusing, requiring constant reference to multiple textbooks, and dependence upon memory of eponym-laden, seemingly endless lists of syndromes. Happily, this “catalogue” state of affairs has changed; major advances in reproductive science have yielded clarification and consolidation. As a result, an informed basis for clinical practice has emerged and is readily applicable. This chapter will present classification of the major problems and our clinical approach to diagnosis. Normal sexual differentiation will be considered in order to provide a basis of understanding for the various types of abnormal development. This is followed by a section on the diagnosis and management of ambiguous genitalia. Some subjects are discussed in other chapters, but brief descriptions will be repeated here in order to present a complete picture. It will be seen that analysis of phenotypic ambiguity follows a fundamental, pervasive theme: too little androgen effect in males, too much androgen effect in females. Normal Sexual Differentiation the gender identity of a person (whether an individual identifies as a male or a female) is the end result of genetic, hormonal, and morphologic sex as influenced by the environment of the individual. It includes all behavior with any sexual connotation, such as body gestures and mannerisms, habits of speech, recreational preferences, and content of dreams. Sexual expression, both homosexual and heterosexual, can be regarded as the result of all influences on the individual, both prenatal and postnatal. Specifically, gender identity is the result of the following determinants: genetic sex, gonadal sex, the internal genitalia, the external genitalia, the secondary sexual characteristics that appear at puberty, and the role assigned by society in response to all of these developmental manifestations of sex. Second, under the control of the genetic sex the gonads differentiate, determining the hormonal environment of the embryo, the differentiation of internal duct systems, and the formation of the external genitalia. It has become apparent that the embryonic brain is also sexually differentiated, perhaps via a control mechanism very similar to that which determines the sexual development of the external genitalia. The inductive influences of hormones on the central nervous system may have an effect on the patterns of hormone secretion 1, 2, 3, 4, 5 and 6 and sexual behavior in the adult. Gonadal Differentiation In human embryos, the gonads begin development during the 5th week of gestation as protuberances overlying the mesonephric ducts. The migration of primordial germ cells into these gonadal ridges occurs between weeks 4 and 6 of gestation. Although germ cells do not induce gonadal development, if the germ cells fail to arrive, gonads do not develop and only the fibrous streak of gonadal agenesis will exist (Chapter 3). At 6 weeks of gestation (4 weeks after ovulation) the gonads are indifferent but bipotential, possessing both cortical and medullary areas, and are capable of differentiation into either testes or ovaries. They are composed of germ cells, special epithelia (potential granulosa/Sertoli cells), mesenchyme (potential theca/Leydig cells), and the mesonephric duct system. Wolffian and mullerian ducts 7 exist side by side; external genitalia are undifferentiated. The distal ends of the short arms of the X and Y chromosomes are called the pseudoautosomal regions because during meiosis the homologous distal short arms of the X and Y chromosomes pair, and interchange of genetic material occurs as in autosomes. The genes in the pseudoautosomal regions are doubly present in both sexes, and therefore escape X inactivation.
