Surveillance of resistance to anti-tuberculosis drugs is an essential component of a monitoring system. The benefits of surveillance are multiple: strengthening of laboratory networks, evaluation of programme performance, and the collection of data that inform appropriate therapeutic strategies. Most importantly, global surveillance identifies areas of high resistance and draws the attention of national health authorities to the need to reduce the individual or collective shortcomings that have created them. Prevalence of resistance among previously untreated patients reflects programme performance over a long period of time (the previous 10 years), and indicates the level of transmission within the community. The prevalence of bacterial resistance among patients with a history of previous treatment has received less attention because surveillance of this population is a more complex process. Re-treatment patients are a heterogeneous group composed of chronic patients, those who have failed a course of treatment, those who have relapsed, and those who have returned after defaulting. In some settings, this population constitutes more than 40% of smear-positive cases. The association between drug resistance and re- treatment has been repeatedly demonstrated, both at the individual and the programme level; however, the prevalence of drug resistance varies greatly among subgroups of this population. This report therefore recommends that all subgroups of re-treatment cases be separately notified and their outcomes reported, and that surveillance of resistance be conducted on a representative sample of this population. This will make the comparison of resistance prevalence within and between countries more robust and will elucidate patterns of resistance among the subgroups, which will allow better definition of appropriate re- treatment strategies. It is now critical that we recognize the importance of the laboratory in the control of tuberculosis. The two previous reports were published in 1997 and 2001 and included data from 35 and 58 settings,a respectively. The goal of this third report is to expand knowledge of the prevalent patterns of resistance globally and explore trends in resistance over time. It includes 39 settings not previously included in the Global Project and reports trends for 46 settings. Data were reported on a standard reporting form, either annually or at the completion of the survey. The prevalence of resistance to at least one antituberculosis drug (any a Setting is defined as a country or a subnational setting (i. Trends in drug resistance in new cases were determined in 46 settings (20 with two data points and 26 with at least three). Significant increases in prevalence of any resistance were found in Botswana, New Zealand, Poland, and Tomsk Oblast (Russian Federation). Previously treated cases Data on previously treated cases were available for 66 settings. Among countries of the former Soviet Union the median prevalence of resistance to the four drugs was 30%, compared with a median of 1. Given the small number of subjects tested in some settings, prevalence of resistance among previously treated cases should be interpreted with caution. Drug resistance trends in previously treated cases were determined in 43 settings (19 with two data points and 24 with at least three data points). A significant increase in the prevalence of any resistance was observed in Botswana. For Henan and Hubei Provinces of China, the figure was more than 1000 cases each, and for Kazakhstan and South Africa, more than 3000. This would allow the rapid initiation of infection control measures and effective treatment. This relationship holds globally as well as regionally and suggests amplification of resistance. Proportions of isolates resistant to three or four drugs were also significantly higher in this region. Central Europe and Africa, in contrast, reported the lowest median levels of drug resistance. Previously treated cases, worldwide, are not only more likely to be drug-resistant, but also to have resistance to more drugs than untreated patients. Accurate reporting on this population will help in monitoring programme performance and developing re-treatment strategies, and provide the required information for survey sampling. Where this is not feasible but there is survey capacity, periodic surveys with separate sampling of new and re-treatment cases should be undertaken. The different types of re-treatment cases should be identified, namely relapse, failure and return after default. Financial support from the international community will be essential for such research. These data have helped identify areas of high prevalence of drug resistance, as well as provided valuable information for policy development; but most importantly, they have served to raise key questions about the behaviour, emergence, and control of drug resistance. These questions can only be addressed through continued expansion of routine surveillance and well organized operational research. The direct benefits come from measurements of the level of resistance in the population and thus quantification of the problem in terms of lives and cost, which allows appropriate interventions to be planned. The introduction of every antimicrobial agent into clinical practice for the treatment of infectious disease in humans and animals has been followed by the detection in the laboratory of isolates of resistant microorganisms, i. Such resistance may be either a characteristic associated with an entire species or acquired through mutation or gene transfer. Resistance genes encode information on a variety of mechanisms that microorganisms use to withstand the inhibitory effects of specific antimicrobials.

In this respect the findings of worldwide drug resistance surveys are revealing buy 50 mg metoprolol overnight delivery arteria labyrinth, in that the prevalence of drug resistance is significantly higher among previously treated patients than among new patients in all regions cheap metoprolol 12.5mg with amex blood pressure chart homeostasis. The only logical inference is that present treatment practices create significant numbers of new resistant cases and amplify already present resistance generic 12.5 mg metoprolol with visa blood pressure of 150/100. This analysis shows a remarkable consistency, both globally and regionally, in the distribution of the major drug resistance types, as well as in the increase in drug resistance prevalence among previously treated cases relative to new cases. It should be noted that prevalence of drug resistance observed in previously treated cases is higher than in new cases in all regions. Since this difference is in great part directly related to the quality of drug treatment, this apparent characteristic could well lead to the development of an indicator that would measure the quality of treatment practices. The addition of a new drug to a failing drug regimen is an effective way of amplifying the drug resistance problem. Monoresistance can only be selected in the presence of a drug concentration leading to the selection of pre-existing mutant bacilli, whereas resistance to two drugs cannot be created simultaneously in the presence of effective concentrations of two drugs. This is because the number of bacilli present in the lesions (108) is usually much lower than the theoretically required bacillary load needed to produce double resistance, i. Results obtained in this study show that the proportions of monoresistance are lower in patients having re-treatment, whereas double resistance remains essentially unchanged. Triple and quadruple resistance are higher by about the same proportion as monoresistance is lower. Amplification caused by re-treatment is the easiest way to interpret these changes, i. The absence of a significant change in double resistance proportions can be explained by selective pressure, leading to an increase in triple and quadruple drug resistance modes thus balancing the inflow from the monoresistance mode. Since resistance in re-treatment cases mostly reflects the quality of recent treatment, these results could lead to the development of an indicator, based on the extent of amplification. The difference between previously treated and new case triple and quadruple resistance proportions could constitute such an indicator. Other pathways can and do exist but their contribution to the drug resistance problem is relatively minor. We can therefore state that monoresistance to H or to S is the foundation for the acquisition of additional drug resistance. Implications The above analysis has shown that there is circumstantial but compelling evidence that either monotherapy or “effective” monotherapy, or both, are more widespread than commonly thought. These results corroborate recently emerging evidence that standard re-treatment regimens containing first-line drugs for failures of standard treatment should be abandoned in some settings. One possible way of breaking the amplification juggernaut would be to replace S in standard regimens and/or to add a third drug to the continuation phase. It expresses the percentage of the variation in the outcome variable that has been explained by the regression on the explanatory variables. For countries conducting surveys on a sample of the population, estimates were generated by applying prevalences determined in surveys to reported notification figures for the corresponding population and thus are dependent upon the level of case-finding in the country and quality of recording and reporting of the national programme.

Limb Axis Formation Four Concepts - much of the work has been carried out using the chicken and more recently the mouse model of development proven metoprolol 12.5mg hypertension young female. Axial myoblasts form the myotome Lateral myoblasts migrate to the limb bud (c) Dermotome skin elements (dermis buy metoprolol 25 mg lowest price arteriogram definition, hypodermis) order 100mg metoprolol with mastercard prehypertension lower blood pressure. Origin of limb muscle cells - Migrations traced by grafting cells from a quail embryo into a chick embryo two species very similar in development quail cells recognizable by distinctive nucleoli Quail somite cells substituted for somite cells of 2 day chick embryo wing of chick sectioned a week later found muscle cells in chick wing derive from transplanted quail somites Dorsal/Ventral Muscle Mass Forelimb Muscles Limb Muscle - Differentiation, Skeletal muscle differentiates the same 1. The nephron, the functional unit of the kidney, is also a classical epithelial/mesenchyme type of interaction. The urinary system is developmentally and anatomically associated with genital development, often described as the urogenital system. Adult nephron structure Nephron Development disorganised mesenchymal cells become a highly organised epithelial tubule Condensation - groups of about 100 cells condense tightly together to form a distinct mass Epithelialisation - condensed cells lose their mesenchymal character and gain epithelial At end of this period formed a small epithelial cyst complete with a basement membrane, cell-cell junctions and a defined cellular apico- basal polarity. Bladder Structure Can be described anatomically by its 4 layers from outside inward: Can be described anatomically by its 4 layers from outside inward: Serous - the superior or abdominal surfaces and the lateral" surfaces of the bladder are covered by visceral peritoneum, the serous membrane (serosa) of the abdominal cavity, consisting of mesthelium and elastic fibrous connective tissue. Detrusor Muscle The adult detrusor muscle consists of three layers of smooth Bladder histology (involuntary) muscle fibres. Anatomically can be described in two parts the abdominal part (pars abdominalis) and pelvic part (pars pelvina). The ureter is composed of three layers: outer fibrous layer (tunica adventitia), muscular layer (tunica muscularis) and mucous layer (tunica mucosa). The muscular layer can also be subdivided into 3 fibre layers: an external longitudinal, a middle circular, and an internal longitudinal. During migration from the sacral region the two metanephric blastemas can come into contact, mainly at the lower pole. The kidneys and ureters usually function adequately but there is an increased incidence of upper urinary tract obstruction or infection. Some horseshoe variations have been described as having associated ureter abnormalities including duplications. Urorectal Septum Malformation thought to be a deficiency in caudal mesoderm which in turn leads to the malformation of the urorectal septum and other structures in Horseshoe kidney the pelvic region. Recent research has also identified the potential presence of a persistent urachus prior to septation of the cloaca (common urogenital sinus). There may also be other anomolies associated with failure of closure of abdominal wall and bladder (epispadias, pubic bone anomolies). In diabetes insipidus there is an excretion of large amounts (up to 30 litres/day) of a watery urine and an unremitting thirst (More? The intermediate mesonephros develops and disappears with the exception of its duct, the mesonephric duct, which will form the male reproductive duct system. A few mesonephric tubules remain as efferent ductules in the male and vestigial remnants in the female. Multicystic Kidney - There is no functional kidney tissue present in the kidney and it is replaced by a multilocular cyst. The rests are further characterised by the time of generation leading to different anatomical kidney locations: early intralobar nephrogenic rests (within the renal lobe) and late pelilobar nephrogenic rests (periphery of the renal lobe) (More? Mesonephric duct (Wolffian Duct) and paramesonephric (Mullerian Duct) contribute the majority of male and female internal genital tract respectively. Reproductive development has a long maturation timecourse, begining in the embryo and finishing in puberty. X inactivation occurs randomly throughout the embryo, generating a mosaic of maternal and paternally derived X chromosome activity in all tissues and organs. This population of cells then lie at the hindgut yolk sac junctional region and later migrate into the genital ridge (germinal ridge) in early embryonic development. The mesonephric duct (purple) differentiates under the influence of Testosterone secreted by Leydig cells. Within the testes these mesonephric tubules grow towards the medullary sex cords and will form the rete teste. The medullary sex cords (orange) form testis cords that later differentiate into solid seminiferous tubules which become hollow and actively produce spermatazoa during puberty. The tunica albuginea (white) covers the testis and bands extend inward to form connective tissue septa. In females, it is produced by supporting gonadal granulosa cells and is involved in ovarian follice development. The paramesonephric duct (red, left) grows forming the oviduct (uterine horn) and the end opens into the peritoneal cavity and Infant ovary terminates in fimbria (finger-like extensions). The cortical sex cords (orange) form after the primary sex cords degenerate and mesothelium forms secondary cords. Vagina Development The embryonic origin of the vagina has been a historically hotly debated issue with several different contributions and origins described. Fetal late embryonic male genital development and now in fetal Paramesonephric duct development we will firstly observe early fetal female development. Indifferent stage ‐ cloaca divided by proliferating mesenchyme forming urorecal septum, ventral urethral, dorsal anal pit. Female Genitalia Development This looped animation shows the development of external female genitalia from the indifferent external structure, covering the approximate period of week 9 to 12. The urogenital folds beneath the genital tubercle remain separate (unfused), forming the inner labia minora and second outer skin folds form the larger labia majora either side of the developing vestibule of the vagina. Note at the top of the animation, the Newborn uterus changing relative size of the genital tubercle as it forms the glans of the clitoris. Note the original cloacal membrane becomes separated into the urogenital membrane and anal membrane (identical to female). The scrotal sac is initially empty and is an attachment site for the gubernaculum, descent of the testes begins generally during week 26 and may take several days. Gonad Descent Both kidney and gonads develop retroperitoneally, with the gonads moving into the abdomen or eventually into the scrotal sacs. During fetal development the gubernaculum and fetal growth in both male and female, changes the gonads’ relative positions finally reaching their adult locations. Ovaries ‐ undergo caudal and lateral shifts to be suspended in the broad ligament of the uterus, gubernaculum does not shorten, it attaches to paramesonephric ducts, causing medial movement into the pelvis.
