This fear of discrimination could have a negative impact on the health and well being of this group mycelex-g 100 mg amex. African people come from diverse communities and it is important that the health adviser is aware of this when discussing prevention discount mycelex-g 100mg on-line, treatment and care. Being aware of specific needs, current issues and policy and the services available for referral will equip the health adviser to meet these new challenges. The health adviser needs to be aware of the legal framework surrounding sex and young people and be alert for signs of sexual abuse and exploitation. However it is good practice to encourage parental involvement until they are 18 for serious or life threatening conditions. Within this guidance the focus is on the legal implications for young people under 16 in line with regional/ national guidance. Young people under 16 years are likely to access sexual health services for a variety of reasons. The principles to which health care personnel adhere to when providing services to this group are laid down in the Children Act 1989 (which applies to all under 18 s) and the Fraser2 Ruling following the Gillick case in 1985. The ethos of the Children s Act is to listen to the3 child s wishes and feelings and to treat children with respect as individuals. In the future consideration will8 9 have to be given to the recommendations of the Sex Offences Review Setting The 10 Boundaries if this becomes law. However, a man has a defence in law if: He is under 24 years old and He has not previously been charged with a life offence, and He believed the girl was aged over 16 years In practice, the police rarely take action in cases where the girl is 13 or over and has consented to sex. However, a girl of 12 years or under cannot give consent to sex in law, and sexual intercourse in this situation is automatically defined as rape. The Law Lords ruled that a girl under 16 could give valid consent for contraception if she were able to understand the proposed treatment and its implications. This principle has come to be known as Fraser Ruling, and this principle of competence has now been extended into most areas of clinical practice. The Fraser Ruling provides guidance for healthcare workers working with young people under the age of 16 in that they can give valid consent for medical examination and treatment depending upon the nature and seriousness of the decision to be made, in conjunction with the child s mental and emotional maturity, intelligence and comprehension of the information they have been given. This requires a healthcare worker to make a judgement in each individual situation/ case. Operational aspects of Fraser ruling It is important that the healthcare worker makes a clinical judgement of the child s competence in each case. Certain criteria need to be met in order for a child to be deemed competent: The young person understands the potential risks and benefits of the treatment and the advice given The value of parental support is discussed. All healthcare workers are obliged to encourage the young person to inform their parents of the consultation. If s/he will not inform a parent, the healthcare worker must explore the reasons why. It is important that the young person seeking contraceptive advice is aware that although the healthcare worker is legally obliged to discuss the value of parental support, the healthcare worker will respect their confidentiality The young person s physical or mental health may suffer if s/he is not prescribed treatment / contraception 315 The young person s best interests require the provision of medication / contraception without parental consent It is good practice for the healthcare worker to record the factors taken into account in making the assessment of the young person s capacity to give valid consent. It is strongly recommended that s/he records what information has been given to the young person, including questions asked and the responses given. This is invaluable if the young person s ability to make decisions were to be questioned or where parents disagree with the decisions made. Any patient under 16 who does not meet the Fraser guidance also needs to be discussed with the consultant. If disclosure is necessary to protect the young person or a third party from significant harm, confidentiality may be broken. It is important absolute confidentiality of information is not stated All young people may be seen with a friend if they wish, at any point throughout the consultation and/or examination. Groups of young people may be seen together where this facilitates access to information on services and health promotion advice It is important the health adviser ensures that the young person understands the possible consequences of sexual activity and is aware of the law relating to underage 316 sex. Safer sex is discussed and condom use demonstrated to all under 16s who are sexually active or potentially sexually active It is advisable the health adviser document which school the young person attends, particularly if they are under 16. This also provides useful data for targeting health promotion It is important the healthcare worker is satisfied that the patient has sufficient understanding of what is involved in any investigations and treatment proposed to give valid consent. This is ideally a multi-disciplinary decision although as the prescriber, the doctor is legally responsible It is important the age of the young person s partner is documented in the notes It is good practice to offer a screen for sexually transmitted infections to all sexually active young people. Many will initially decline, but may agree to a screen at a later date when they have developed greater confidence in the clinic staff. Where urine tests or self-taken swabs are available, they can be offered to young people who decline a genital examination It is advisable the healthcare worker discuss and document follow-up arrangements It is important that any concerns about a young person are discussed with other staff involved in their care and further concerns discussed with the senior doctor or consultant. It is recommended health advisers work in their referral area with the relevant school nurses, practice nurses, young peoples services, and contraceptive services to facilitate access. Specific flyers for the service can therefore be used and suitable health promotion leaflets/ materials made available Consider developing a designated young person s service, where young people need not see other adult attenders. There can be appropriate music/ videos, leaflets and posters for younger patients to make a more welcoming environment.

Orthoptists might be in the media, even though the alignment of the regarded as physiotherapists of the eyes and eyes has not been disturbed.

This type of accommodative squint can shows certain features: be fully corrected by wearing spectacles: when the glasses are on, the eyes are straight; and Impaired Snellen visual acuity but usually when they are off, one eye turns in. More often, able to decipher vertical lines of letters the squint is only partially accommodative and better than horizontal ones. The convergent squint associated with Small residual squint or, if not, the affected hypermetropia is the commonest type of eye relatively hypermetropic. In a similar manner, a corneal opacity, as might result from herpes simplex keratitis or The diagnosis of amblyopia can be by exclu- injury, can cause a squint to appear. A com- sion but it must never be reached without a pletely blind eye from whatever cause tends to careful examination of the eyes.

That is to say, we must realise that tive error but there might be an asymmetry of 114 Common Eye Diseases and their Management the insertions of the extraocular muscles as a possible cause of squint. There is a group of con- ditions, known as musculofascial anomalies, in which there is marked limitation of the eye movements from birth in certain directions. They are accompanied by abnormal eye move- ments, such as retraction of the globe and nar- rowing of the palpebral ssures on lateral gaze. This is seen in school children sometimes with a background of domestic or other stress. The eyes tend to overconverge and overaccom- modate, especially when being examined. Abnormalities of Facial Skeleton This is not a common cause but it should be kept in mind. Diagnosis History When faced with a case of suspected squint, certain aspects of the history can be helpful in assisting with the diagnosis. Sometimes, gives the appearance of a squint but the corneal reexes show that this is not the case. The mother herself is nervous, a useful technique is to introduce usually the best witness.
