RESUMO
Children with chronic medical conditions face many challenges when considering sport participation. Compared with their healthy counterparts, they are often discouraged from physical activity or sports participation because of real or perceived limitations imposed by their condition. Prescribed exercise should be based on the demands of the sport, the effect of the disease on performance, and the potential for exercise-induced acute or chronic worsening of the illness or disability. This article will focus on several examples of chronic medical conditions and the clinician's role in providing advice about sport participation.

This case-controlled study aimed to evaluate the existing oral health status in children and adolescents with haemophilia. A total of 50 haemophilia patients and 50 matched controls aged seven to 16 years were recruited into the study. Clinical examination was carried out to determine dental caries experience, oral hygiene status and gingival condition in these two groups. Information regarding previous dental history, oral hygiene practices and dietary habits were also obtained. No significant difference was found in mean caries experience in primary and secondary dentitions (P = 0.86 and 0.32) and in Simplified Oral Hygiene Index (OHI-S, P = 0.20) between both groups. However, a significantly higher proportion of haemophilia patients (24%) had better oral hygiene status as compared to the controls (2%, P = 0.004). Furthermore, there was a significant difference in Modified Gingival Index (MGI, P = 0.02) between the two groups with the study group having less gingival inflammation. A total of 88% (n = 44) of the haemophilia patients were registered and received dental treatment in specialist dental clinics. More than half (56%, n = 28) had frequent dental visits and only one-third of the haemophilia patients had history of hospitalization due to oral problems. There was no significant difference in oral hygiene practices and dietary habits between both groups. In general, haemophilia children and adolescents in this study had similar caries experience, a significantly better oral hygiene status and gingival health as compared to healthy controls. The main reason for this is the multidisciplinary approach implemented by medical health-care professionals as primary care provider and the dental team.

Management of patients with hereditary bleeding disorders in dentistry causes considerable problems. This study examined different aspects of dental health or disease of Lithuanian children and adults with haemophilia and compared them with the general population. Two study groups of cases and controls were formed. Cases were recruited through census sampling and controls were randomly chosen from the general population matched for gender, age and place of residence. Dental health of permanent and deciduous dentitions was assessed by one examiner employing the WHO Criteria for Oral Health Surveys. The following aspects of dental health/disease were considered: overall caries experience, treatment experience, unmet dental treatment needs and the presence of functional dentition. Data were collected from 76 patients with haemophilia among which 27 were children and 49 were adults and a control group of 76 subjects comprising 30 children and 46 adults. Children with haemophilia had a significantly lower overall caries experience and less unmet dental treatment needs in deciduous teeth as compared to healthy children. In permanent dentitions, overall caries experience, unmet dental treatment needs or treatment experience did not differ between cases and controls either in older children or adult cohorts. There were no differences between the study groups regarding the functional dentition-related indices. Healthier deciduous teeth were observed in children with haemophilia than in children without haemophilia, but other dental health or disease-related outcomes did not differ between cases and controls.

CASE REPORT: A 46-year-old man with severe hemophilia A, stage A2 HIV infection and chronic hepatitis C genotype 1A, for whom the treatment plan included implant-supported prostheses in 2 mandibular edentulous sections. The protocol followed included factor VIII replacement concentrate and oral antifibrinolytic therapy. The right mandibular section was fitted with 3 Straumann implants (Ø 4.1 mm, length 10 mm), and the left mandibular section received 2 implants of the same characteristics. The patient showed no postoperative complications. After implant placement, the patient attended scheduled review appointments. After a 3-month period of osseointegration, the prosthesis was fitted. CONCLUSIONS: Although, in this case, the treatment proved successful 2 years postrehabilitation and the protocol used seems safe and effective, long-term prospective studies are needed to evaluate the implant success rate in these patients.

Female carriers of haemophilia might suffer from increased bleeding tendency therefore the assessment of the bleeding risk is very important for improving care. This single-centre study documents the occurrence of bleedings in 46 carriers of haemophilia A including bleeding after tooth extraction (77%), easy bruising (67%), postsurgical bleeding (61%), menorrhagia (50%) or prolonged postpartum bleeding (43%). The F8 gene mutation of all 46 carriers (median age: 36.5 years, 15-80 years; mean FVIII:C activity: 59 ± 24.45%; normal range: 64-167%) was determined, and family history of haemophilia was recorded. For analysis, the bleeding tendency of the carriers was differentiated by severity into three groups. There was no statistically significant difference of FVIII:C between these groups. However, a correlation was found between the severity of bleeding tendency and the type of F8 gene mutation (P < 0.05) as well as the severity of haemophilia in affected male relatives (P < 0.0005). Results show that even carriers with a FVIII:C activity as high as 50-60% are at increased risk of bleeding. Incidence and intensity of bleeding symptoms of haemophilia A carriers are high and correlated with the phenotype of the male haemophilic relative and the underlying F8 gene mutation.

Hemostasis is a finely balanced process in which an insult to a blood vessel wall, either by injury or surgical intervention, stimulates a pair of parallel, yet associated, pathways that lead to the termination of blood loss. The coagulation cascade is initiated by the interaction between exposed subendothelial tissue factor and circulating blood and includes a series of amplification steps that result in thrombin generation. Concurrently, exposed subendothelial collagen stimulates platelets, which, in the presence of thrombin, are consolidated by fibrin to form a blood clot, thus terminating blood loss. Multiple inherited and acquired abnormalities in these pathways can seriously compromise hemostasis. Furthermore, several drugs, including over-the-counter preparations, also adversely affect hemostasis. These present significant concerns to the dentist conducting invasive procedures as they can prolong postoperative bleeding, impair wound healing and increase risk of infection. In this article, we review the current knowledge of bleeding abnormalities and discuss preoperative systemic precautions and intraoperative hemostatic measures.

To gain greater insight into the nature of the bleeding tendency in hemophilia, we compared the spatial dynamics of clotting in platelet-free plasma from healthy donors and from patients with severe hemophilia A or B (factor VIII:C or IX:C<1%). Clotting was initiated via the intrinsic or extrinsic pathway in a thin layer of nonstirred plasma by bringing it in contact with the glass or fibroblast monolayer surface. The results suggest that clot growth is a process consisting of two distinct phases, initiation and elongation. The clotting events on the activator surface and the preceding period free of visible signs of clotting are the initiation phase. In experiments with and without stirring alike, this phase is prolonged in hemophilic plasma activated by the intrinsic, but not the extrinsic pathway. Strikingly, both hemophilia A and B are associated with a significant deterioration in the elongation phase (clot thickening), irrespective of the activation pathway. The rate of clot growth in hemophilic plasma is significantly lower than normal and declines quickly. The resulting clots are thin, which may account for the bleeding disorder.

Hemophilic patients must be thought of as special patients. Since routine dental procedures, however, do not usually involve bleeding, there is no contraindication to general dental treatment for hemophiliacs. Aspirin-containing compounds should never be prescribed. Caution must be used with local anesthetic block techniques. Preventive dentistry is vital to the younger hemophiliac; older hemophiliacs may require extensive treatment to restore mouths that have been neglected for years. Surgical dental procedures are now considered possible for hemophiliacs and may be performed on an outpatient basis, but they must be judiciously coordinated by the dental and medical team.

A brief discussion of the patient with bleeding problems inevitably attempts to make a complex subject simple. Obviously this is not possible, yet there is a remarkable degree of consistency today in the way such patients are managed. The research and technology in progress offers continued hope for more knowledge and technical capability. The dentist who must deliver a health service predicated upon the surgical approach to treatment must continue to keep abreast of new developments. He must be comprehensive in the evaluation and management of his patients. This requires a sense of responsibility and the willingness to share responsibility with those physicians best able to deal with the problem.

This article reviews the therapeutic problems that arise in the dental management of hemophilia patients with inhibitor and suggests an anesthesia technique that may eliminate the need for factor replacement during restorative procedures. Intraligamentary anesthesia was used during restorative procedures that were performed throughout an 8-year period on a patient with factor VIII inhibitor. Multiple restorative procedures were accomplished without the use of replacement factor and with no postoperative bleeding. This technique, in consultation with the patient's physician, may be performed by most general practitioners in their private offices.

Nitrous oxide analgesia is presented as the analgesic method of choice in medically compromised patients. The resemblance between the action of nitrous oxide and that of morphine is emphasized. The combination of the opiate-like action of nitrous oxide with the advantages of an inhalation technique makes it preferable and superior to parenteral opiate administration. It may thus be termed as an inhalation "opiate".Since its introduction into clinical use by Wells in 1844 (1), nitrous oxide (N(2)0) has been applied as an anesthetic and analgesic agent in various medical situations, including dentistry (2). The development of equipment affording safe administration of accurate concentrations of either pre-mixed or adjustable N(2)0 and oxygen enabled the application of "relative analgesia" as an important technique in the relief of pain. The pharmacological action and analgesic properties of N(2)0 received renewed interest after Berkowitz et al (3) showed the resemblance between its mode of action and that of opiates. Recent human and animal studies indicated that N(2)0 activates the endogenous opiate system(s) in a manner similar to that of morphine (4). The availability of an analgesic gas which, on the one hand, mimics opiate action whilst on the other hand its administration is continuously adjustable, as opposed to other modes of sedation, makes it into an ideal adjunct in dental procedures. Owing to its minimal side effects, the use of N(2)0 is especially recommended in the management of anxious children and medically compromised patients.This report presents three illustrative patients in whom nitrous oxide proved to be the drug of choice during dental procedures.

The physiopathology of the hemorrhagic blood coagulation disorders caused by genetic or aquired problems is described. Among the former the most frequent ones include the hemophilia of type A-B and the von Willebrand disease, among the latter the use of oral anticoagulant constitutes the most frequent cause. If the are not subjected to an adequate haemostatic prophylaxis, both patients with hemophilia and von Willebrand disease present a serious haemorrhagic risk as a consequence of dental practice. As far as the use of anticoagulants is concerned, a periodical monitoring of the time of prothrombin (PT) is needed to find the right dosage (TP between 20%-30% or INR--international normalized radio between 2 and 3.5). Values over this range cause an increase of the hemorrhagic risk, while lower values involve an increased risk of thrombotic events. According to the authors the patients with the hemorrhagic diathesis show a precise handicap, caused both by his illness and by environmental elements, such as the fear of doctors for the haemorrhagic complications consequent to a therapeutical operation, fear that often leads to neglect important medical measures, in particular dental measures. The specialized dental surgeon has to mantain a strict cooperation with the hematologist in order to arrange an appropriate procedure of the prophylaxis. As far as the hemostatic prophylaxis is concerned, the use of the dermopressin (DDAVP), in patients with hemophilia A and von Willebrand disease, guarantees the realisation of dental practice without hemorrhagic risk. On the contrary, the use of the tranhexanic acid on patients in an anticoagulant oral treatment gives hemostatic security and makes it possible to carry on the therapy and the out-patient treatment.

After the formation of a platelet-plug, generation of fibrin is necessary for its stabilization. Both congenital and acquired deficiencies of clotting factors occur, leading to retarded formation of fibrin. In congenital disorders, preoperative correction is possible and necessary. In acquired deficiencies, the type and feasibility of correction depends on the cause of the deficiency.

Recommendations for dental preventive strategies and treatment planning were originally developed through consensus meetings by the Scottish Oral Health Group for Medically Compromised Patients and published in 2003 as a Guideline. The United Kingdom Haemophilia Centre Doctors' Organisation (UKHCDO) Dental Working Party has updated these recommendations following the AGREE II approach (www.agreetrust.org), involving a literature search, a review of national and international guidelines and after seeking the opinions of haemophilia treaters in the United Kingdom by an online survey. Where possible, evidence from the literature is graded according to the 'GRADE' system (www.bcshguidelines.com/bsch_process/evidence_levels_and_grades_of_recommendations/43_grade.html); however, overall there is a lack of robust data and most studies have methodological limitations. The objective of this guidance, which is largely consensus-based, is to assist dental practitioners in primary and secondary care to provide routine dental care for patients of all ages with congenital bleeding diatheses in order to improve overall access to dental care. The guidance may not be appropriate in all cases and individual patient circumstances may dictate an alternative approach. Date for guideline review: May 2016.
