For this reason, we need to highest attainable standard of health care (Article 24) as redefne the term, tropical pediatrics, as care of children shown in Figure 1. According to article 28, the not only in the tropical countries, but also in the states are obliged to make primary education compulsory non-tropical countries.

Subsequent to India’s accepting the obligations of united nations convention on the rights of the child, following are some of the initiatives launched by India towards advance- ment, promotion and protection of child rights: National commission for protection of child rights. A global perspective for the feld of pediatrics is, therefore, not just desirable, but mandatory. Since children are usually not in a position to speak out and advocate for themselves, it is the pediatricians who need to advocate for them in order to advance children’s well-be- ing and welfare.

Furthermore, pediatricians need to provide a platform or contribute to it for promotion of coordinated child- centric endeavors with involvement of like minded groups of social workers, teachers, psychologists, child rights activists and community leaders. With some variations, which are bound to be there from region to region, observations from various parts of India indicate a remarkably similar pattern.

Symptom and condition screeners help identify health conditions to identify patients who may benefit from treatment. Patient expectation, goal assessment, and satisfaction questionnaires help clinicians understand the patients’ point of view regarding their treatment goals and expectations so that the clinician can enhance the probability of a satisfactory outcome. The development process steps from conceptual design through cognitive debriefings, psychometric, and linguistic validation are described in detail earlier in this section. This chapter introduces you to some useful, validated questionnaires for female urological practice. Most clinicians recognize that many patients find it difficult to articulate their health issues for a variety of reasons such as embarrassment about their problem or lack of medical knowledge or language. Providing questionnaires that screen for common urogynecological conditions to patients before their medical consultation can help focus the medical visit. In this section, validated screeners, their individual strengths and weaknesses, and how to obtain them are presented. When choosing and interpreting the results of screeners, the sensitivity and specificity of the measures should be considered. Sensitivity is the probability of a positive screener score in a patient with the condition. At the same time, the screener should have a high likelihood of correctly identifying individuals without the condition—specificity. Screeners alone are not diagnostic; clinicians should verify the indicated condition before determining treatment. Importantly, with screeners, responsiveness is not assessed; however, the sensitivity and specificity of each tool is critical. In this section, we describe some commonly used screeners and factors such as which populations the screener can be used in, its reliability and validity, its sensitivity and specificity, and its availability of valid linguistic translation. The final instrument was validated and showed good reliability, validity, and sensitivity/specificity. The questionnaire has been translated and validated in at least 14 languages and is for both men and women. This is based on four questions that measure the severity of day- and nighttime urinary frequency, urgency, and bladder pain over the past month . Internal consistency and test–retest reliability were found to be high for the scale. A score of 0–6 has been suggested as indicative of mild symptoms, 7–14 of moderate symptoms, and 15–20 of severe symptoms . Urinary Incontinence Medical, Epidemiological, and Social Aspects of Aging Questionnaire The Medical, Epidemiological, and Social Aspects of Aging questionnaire is a 15-item tool developed to screen for urinary incontinence and other urinary symptoms in noninstitutionalized women . Frequency of symptoms is measured on a 4-point scale from “never” to “often” with higher scores indicating more frequent symptoms. There are two subscales: six items that assess stress incontinence and nine items for urge incontinence and other urinary symptoms; each subscale was rescored to have a range from 0 to 100 . Patients with an overall score of eight or more on the V8, or four or more on the V3, are directed to seek medical advice. Sexual Dysfunction (Refer Also to Chapter 64) There are several screeners that can be used to detect sexual dysfunction. It has been developed as a brief self-report instrument for assessing sexual function in women . It was developed on a female sample of normal controls and age-matched subjects and provides scores on six domains of sexual function (desire, arousal, lubrication, orgasm, satisfaction, and pain) as well as a total score. Although frequently reduced to a single, one-dimensional item in clinical practice “Are you satisfied with your treatment? At its most basic level, satisfaction is a comprehensive evaluation of several dimensions of health care based on patient expectations and provider and treatment performance. As an outcome measure, patient satisfaction allows health-care providers to assess the appropriateness of treatment according to patient expectations. Although the importance of patient satisfaction assessment is often ignored, it plays a key role in assessing outcomes. In chronic diseases, 206 where patients must live with treatment, patient satisfaction may be the distinguishing outcome . Evidence suggests that patient satisfaction may be more sensitive to change than the quality of life in clinical trials in chronic diseases . Satisfaction with treatment provides information on treatment effectiveness  and is believed to affect clinical outcome . It has been shown that high levels of patient satisfaction with medication correlates with treatment compliance, maintenance of a relationship with a specific provider, and disclosure of important medical information . High levels of satisfaction have also been positively associated with good health status, fewer medical encounters, and shorter hospital stays . In contrast, dissatisfaction with medication may impact a patient’s likelihood to register formal complaints about services, engage in legal action against a clinic or provider, or provide unfavorable publicity about a clinic . Preliminary work that suggest satisfaction with pain treatment can influence patient behavior, particularly regarding their intention to continue to take medications . Satisfaction, if measured correctly, differs from other patient-reported, clinician-reported, and objective outcome measures, in that it addresses the influence that expectations can have on satisfaction. For instance, health status instruments measure the outcomes of treatment (whether they be physiological, symptoms, or impact); satisfaction assessments measure the level of satisfaction with these outcomes, given a level of expectations about treatment outcome. The role that expectations play in satisfaction assessments cannot be minimized: a patient with high expectations for treatment outcome may remain dissatisfied even after “successful” treatment because the patient’s expectations for treatment benefit were not in alignment with what could be reasonably expected in terms of efficacy. Similarly, a patient with low expectations for treatment benefit can end up extremely satisfied with the treatment regardless of whether or not it worked simply because any treatment benefit, even small, is seen as meeting low expectations. Although the role of expectations in satisfaction assessments cannot be ignored, they can be accounted or controlled for by ensuring that patient expectations are measured at the time a patient initiates treatment. There are both generic- and condition-specific questionnaires to assess patient satisfaction with urogynecological treatment.
However purchase online fluvoxamine anxiety symptoms or something else, the N + 1 stimulus reaches the reset reentrant circuit when it is relatively refractory and is conducted more slowly in the orthodromic direction buy 100mg fluvoxamine with visa anxiety symptoms face numbness, producing an increase in the return cycle to 450 msec discount 50mg fluvoxamine with mastercard anxiety therapist. F: Because the impulse is slowed generic 100mg fluvoxamine mastercard anxiety symptoms and signs, when the N + 2 extrastimulus arrives, the tachycardia circuit will still be refractory and may even be more so, resulting in further prolongation of the return cycle. Thus, despite the presence of a fully excitable gap (a flat resetting response to single extrastimuli was observed at coupling intervals of 350 to 250 msec), prolongation of conduction in the orthodromic direction by N + 2 and subsequent extrastimuli produce an increased return cycle on cessation of pacing. Thus, during entrainment, the return cycle is not necessarily an accurate reflection of the extent of the excitable gap as determined by single extrastimuli. It is, in fact, the response to the (N + 1)th stimulus that determines the ultimate conduction time through the reentrant circuit during overdrive pacing. If the (N + 1)th stimulus arrives at the circuit when it is still relatively refractory, prolongation of the return cycle or termination will occur, regardless of whether use of a single extrastimulus (N) demonstrated a flat curve. However, if the number of stimuli following the nth complex producing resetting is limited to one or two, particularly at long cycle lengths, termination may not be observed, although the return cycle will be progressively longer following each stimulus. Entrainment is not present until two consecutive postpacing intervals are identical. In general, the return cycle measured from the stimulus that first produces resetting will be less than the return cycle following cessation of pacing after 10 additional cycles when pacing is carried out at short P. Continued pacing at that cycle length usually produces either a fixed first postpacing interval with a return cycle longer than that observed following resetting of the tachycardia by a single extrastimulus (Fig. Thus, if only the return cycle following entrainment is used to analyze the “excitable gap,” an increasing curve suggesting decremental conduction may result, even though a flat response is observed with single and/or double extrastimuli. Analog recording of this phenomenon and graphs of the return cycles in response to overdrive pacing are shown in Figures 11-174 and 11-175 This has led to conflicting interpretation of the nature of the excitable 1 122 123 316 317 319 326 342 343 gap. Nonetheless, I generally agree with the conclusion of these studies, which held that the presence of any of these findings suggests a reentrant mechanism. This has unfortunately led to many misconceptions about what entrainment means and a lack of understanding of the differences between entrainment and resetting by many cardiologists. None of the initially proposed criteria to recognize entrainment are required to demonstrate resetting of the tachycardia circuit, which is the physiologic basis for entrainment. As a result, the criteria for entrainment are less frequently demonstrable than the phenomenon of continuous resetting. Thus, although the presence of any of these criteria always means continuous resetting is occurring, it is important to recognize that resetting occurs in their absence more commonly than in their presence. Comparison of resetting and entrainment of uniform sustained ventricular tachycardia; further insights into the characteristics of the excitable gap. When subsequent beats are added to the drive train at the same cycle length, no increase in return cycle is noted. However, the return cycle increases to 520 msec following the nth + 1 beat ( middle panel) and continues to increase with each incremental beat until the tachycardia terminates following the sixth paced beat. Comparison of resetting and entrainment of uniform sustained ventricular tachycardia; further insights into the characteristics of the excitable gap. The ability to demonstrate surface electrocardiographic fusion and thus fulfill two of the proposed criteria for “entrainment” depends on enough of the ventricular myocardium being depolarized by both the stimulated and tachycardia wavefronts so that the presence of both wavefronts can be recognized (i. This is an identical situation to that described earlier (see the section entitled Resetting with Fusion). Surface electrocardiographic fusion is, therefore, not necessary to define the presence of entrainment. Entrainment of ventricular tachycardia: explanation for surface electrocardiographic phenomena by analysis of electrograms recorded within the tachycardia circuit. The stimulated impulse would also conduct orthodromically; thus, resumption of the tachycardia would occur with the presystolic electrogram orthodromically activated. Therefore, the last stimulus of the train activates the presystolic electrogram antidromically to produce retrograde capture and simultaneously conducts orthodromically through the circuit. Local fusion and, hence, the possibility of fusion (albeit nonrecognized) outside the circuit can only occur if the presystolic electrogram is activated orthodromically. In all such cases, the return cycle measured at this local electrogram will equal the paced cycle. If pacing is performed at a shorter cycle length, then the paced impulse can penetrate the circuit antidromically and retrogradely capture the presystolic electrogram so that no exit from the tachycardia circuit is possible. When pacing is stopped, the impulse that conducts antidromically also conducts orthodromically to reset the reentrant circuit with orthodromic activation of the presystolic electrogram. An example of entrainment during right ventricular pacing at a cycle length of 310 msec is shown in the upper right panel. Note that the initial components of the presystolic left ventricular electrogram (denoted by the black arrows) remain unchanged during entrainment when compared with their morphology during tachycardia. The systolic component of this electrogram (small red asterisk) is altered at the lower right during pacing at a shorter cycle length (260 msec) the initial component of the left ventricular electrogram changes (red arrow). Also note that the left ventricular electrogram recorded during entrainment is almost identical to the electrogram recorded during right ventricular pacing in sinus rhythm (lower left). The orthodromic activation time to the presystolic electrogram (green arrow) remains unchanged. Entrainment of ventricular tachycardia: explanation for surface electrocardiographic phenomena by analysis of electrograms recorded within the tachycardia circuit. This should be classified inapparent fusion and is depicted in the right-hand panel of Figure 11-178. This can be detected only by analyzing whether or not the presystolic electrogram is orthodromically or antidromically activated. Thus, one can demonstrate two pathways of conduction to the presystolic electrogram: one that has a more prolonged conduction time—that is, the orthodromic pathway in the circuit—and one that results in antidromic capture of that electrogram. Thus, stimulation from the same site in the heart can manifest two activation times to the same point in the reentrant circuit. This has led to the concept that the orthodromic limb of the circuit exhibits a long 1 122 319 326 327 337 342 343 conduction time. During orthodromic activation, the stimulus to local electrogram interval is greater than during antidromic capture (Fig. Note that in Figure 11-180 the interval from the stimulus to local presystolic electrogram remains flat over a period of cycle lengths during both orthodromic and antidromic activation, suggesting that no decremental conduction was present. Although others have “demonstrated” the so- 326 327 335 342 343 called “decremental properties” in the orthodromic limb, , , , , this concept is misleading. Slowing is secondary to interval-dependent conduction delay through tissue that has only partially recovered excitability when the ( n + 1)th stimulus reached the circuit. As noted earlier one can observe a flat resetting curve in response to single extrastimuli, yet when rapid pacing is initiated, following the first extrastimulus producing resetting ( nth stimulus) the subsequent stimuli can occur during the relative refractory period of the excitable gap and prolong the return cycle. This prolonged stimulus to presystolic electrogram compared to a single extrastimulus does not imply decremental properties analogous to that of the A-V node (Fig. If it arrives at a fully excitable state, the stimulus to local electrogram will be the same as observed using a single extrastimulus regardless of the cycle length of pacing. This is demonstrated in analog records in Figure 11-176 and in graphic representation in Figure 11-180. The prolongation of the stimulus to local electrogram interval at shorter cycle length means that the ( n + 1)th stimulus has encountered partially excitable tissue in the reentrant circuit. The circles represent sites within the reentrant circuit just proximal to the exit site from the presystolic electrogram is recorded.

In fact, reconstruction techniques forming the incisions suggested by Mc Evitt; in addition he often undertake aesthetic otoplasty techniques and vice versa.

While a few postmortem studies of patients in whom A-V nodal ablations had been performed have demonstrated intact compact nodes cheap generic fluvoxamine uk anxiety symptoms pain in chest, the amount of injury to the transitional cells discount fluvoxamine 100mg amex anxiety symptoms tight chest, injury but not death to the compact node buy fluvoxamine on line anxiety chest tightness, and effect of uncoupling of superficial atrial fibers from the subjacent compact nodal transitional cells is not understood purchase fluvoxamine 50mg on line anxiety 12 step groups. We have seen three “slow” pathway blocks produced by lesions delivered at the apex of the triangle of Koch. Nonspecific effects altering summation and inhibition of A-V nodal conduction as well as the anisotropy of the compact node and transitional cells are probable contributing factors to the successful ablation of A-V P. The persistence of dual A-V nodal pathways in 40% of patients who remain free of clinical arrhythmias suggests an alteration in the functional capabilities of the circuit to perpetuate themselves, perhaps related to change in the size of the potential reentrant circuit (e. I do not think the results of ablation provide any clue in helping to resolve the issue of whether or not some part of the atrium is required for A-V nodal reentry. Clearly, in the vast majority of, if not in all, cases, successful ablation is associated with a change in A- V nodal conduction of one form or another. In addition, successful ablation almost always is associated with the induction of junctional rhythms and not ectopic atrial rhythms. Most A-V nodal conduction curves following A-V nodal modification demonstrate an upward shift to the right of one or both pathways following successful ablation. Regardless of the site of ablation, dual A-V nodal pathways may still be present, conduction over the fast or slow pathway may be slower, yet no A-V nodal tachycardia results. The overall success rate of modification of the A-V node to cure A-V nodal reentrant tachycardia can be expected to exceed 95%. While accelerated junctional rhythms appear to be necessary to achieve successful ablation, they are not necessarily sufficient. The ideal end points include loss of slow pathway conduction, a prolonged Wenckebach cycle, and persistence of intact antegrade and retrograde conduction. If dual pathways are present with single echo complexes, recurrent clinical A-V nodal reentry is rare. If dual pathways or single echoes can be produced over a wide range of coupling intervals, we have found that the addition of isoproterenol and/or atropine often induces more sustained A-V nodal tachycardia. As such we usually give additional lesions until an echo zone of 30 msec or less or loss of slow pathway conduction is achieved. In all instances, prior to termination of the study, stimulation is repeated following isoproterenol and/or atropine. Absence of slow pathway conduction or a very narrow window of slow pathway conduction is associated with a recurrence rate of less than 2%. The risk of heart block appears to be less than 1% and does not seem to be able to be improved upon no matter how careful the investigator. Congenital abnormalities are often associated with displacement of the A-V node, and a forme fruste of these congenital abnormalities (which may go undetected) may be related to inadvertent A-V block. In the absence of complete heart block, prolonged A-V conduction can be produced, which can lead to a pacemaker syndrome or exercise intolerance, should Wenckebach occur at fast rates. While some believe that prior slow pathway ablation indicates a high incidence of A-V block should fast pathway ablation be undertaken and vice versa, the data supporting this fear is at best limited. We have not had any evidence of A-V block in the nearly dozen patients who have been referred to us for failed ablations elsewhere. It is, however, a generally held belief that repeated ablations for A-V nodal tachycardia are associated with a higher risk of A-V block, and patients should be made aware of this. Cryoablation is used in some centers, particularly in pediatric electrophysiology, in an attempt to reduce the risk of inadvertent A-V block. Although the use of larger tip (6 mm) catheters has eliminated the concept of cryomapping, cryoablation certainly offers the security of perfect catheter stability during energy delivery. Although traditionally it is associated with digitalis toxicity or in the early period following cardiac surgery, it also has a paroxysmal form and may cause significant symptoms. If an atrial extrastimulus is delivered during tachycardia when the His is refractory perturbs the timing of the next His, this confirms participation of the slow pathway, consistent with A-V nodal tachycardia. Alternatively, if an earlier extrastimulus advances the timing of the His immediately following without terminating the tachycardia, this indicates that the retrograde fast pathway is not required for the maintenance of the tachycardia, diagnosing junctional tachycardia. Ablation of junctional tachycardia can be successful, but is not as effective as for A-V nodal tachycardia and has a higher incidence of heart block. The largest included 11 patients (including 5 adults), and ablation was successful without heart block in 9 patients. The strategy in this series was ablation at the site of earliest atrial activation in patients with V-A conduction, and empiric slow pathway ablation in the setting of V-A block. Ablation for atrial fibrillation is widely performed using catheter and surgical techniques; the optimal indications for either strategy are still being determined. Ablation of Atrial Tachycardia Atrial tachycardias that are incessant and due to abnormal automaticity or triggered activity are often drug refractory and as such are most often treated by ablation. Microreentrant atrial tachyarrhythmias are more easily managed with drugs so that ablation is not usually considered until there is a drug failure. Macroreentrant atrial tachycardias are more like atrial flutter and will be discussed in that subsection. Incessant atrial tachycardias are an important cause of tachycardia-mediated cardiomyopathy. These atrial tachycardias can occur from a wide variety of areas in the heart but seem to have the propensity for the crista terminalis, both atrial appendages, the coronary sinus, the regions of the mitral and tricuspid annulae, as well as the pulmonary veins. It is important to recognize that sedation of these patients might terminate the tachycardia. If the tachycardias are not incessant, catecholamine infusion and/or use of theophylline or atropine (in the case of a catecholamine-mediated triggered activity) may be necessary to induce the arrhythmia. The first step in mapping atrial tachycardias is using the electrocardiogram to regionalize the source of the arrhythmia. In general, P1 waves associated with tachycardias arising near the septum are narrower than those arising on the right or left free wall. Most left atrial tachycardias are approached via a transseptal catheterization, which in many laboratories is performed under intracardiac ultrasound guidance. The fossa is at the level of the His bundle catheter and about 2 to 3 cm posterior to it. The amplitude of the voltage of electrograms at the fossa is somewhat lower than the surrounding tissue. The fossa ovalis may be stained with dye prior to its puncture to verify location, even if ultrasound is used. Some operators prefer to heparinize prior to the transseptal puncture to avoid thrombus which can be introduced into the left atrium via the transseptal sheath. A simple roving catheter using unipolar and bipolar signals to find the site with the earliest bipolar and unipolar signals. Unipolar signals can be filtered or unfiltered, but the unfiltered signals offer directional information. Low-amplitude early signals followed by a sharper discrete signal may represent an early component of a fragmented electrogram or a far field signal associated with a second, discrete local signal. This is most likely to happen in the superior posterior right atrium where a low-amplitude signal preceding a sharper higher- frequency signal may actually represent electrical activity generated from the right superior pulmonary vein.
