The reason for the neurological signs in ner- vous ketosis are not known but may be caused simply by hypoglycemia, acetoacetic acid levels that are toxic to the brain, or through the production of isopropyl alcohol A from acetoacetic acid breakdown in the rumen. A degree of hepatic encephalopathy could contribute to neuro- logic signs in these cattle, but we are unaware of studies to conrm or deny this theory. Signs Signs observed in cattle affected with nervous ketosis vary from recumbency to aggression. Many cows having ner- vous ketosis act demented, constantly licking one or more spots on their own body or on inanimate objects. Other cows, if conned, show pro- pulsive tendencies by constantly leaning into a stanchion or tie stall. Cattle not conned to tie stalls may wander about, appear ataxic, blind, and will head press. Some severely affected cattle become recumbent as their degree of hypoglycemia B worsens. Once recumbent, the patient may appear simi- lar to hypocalcemic or hypomagnesemic patients. Overly fat periparturient cows may develop severe ketosis and signs of nervous ketosis within days following calving.

The sheer size and diversity of this population makes any attempt to cover all of the relevant issues in depth somewhat problematic. This section therefore aims to cover core issues relevant for sexual health advisers working with this client group. For a more detailed analysis of some of the subjects covered a reading list is provided at the end of the chapter. Much of the advice and information provided in the general sections of this handbook will also apply to gay men. Most gay men grow up in an environment where there continues to be both overt and covert hostility towards men who are sexually attracted to other men. These negative messages not only affect and influence gay men but also those working with them on sexual health issues. A reflection of the growing realisation that for safer sex and risk reduction messages to be effective other factors like self esteem, mood, general sexual health, alcohol and drug use have to be taken into account. Though the patient in front of you might be behaviourally homosexual, bisexual or heterosexual it is the patient s perception of his sexuality which should guide you in the work you do with him and the language you use. To self identify as gay in our society suggests (to varying degrees) an acceptance and awareness of shared experience and identification with other homosexual men. It also suggests a perception of difference from the experience of heterosexual males. The use of the word gay might therefore be seen as partly descriptive of a cultural and community identity as well as of sexual identity. A bisexual man is usually defined as a man who is sexually attracted to both women and men. Though a bisexual man is someone who behaviourally might have sex with both men and women his choice might be to identify his sexuality as either bisexual or gay. Sexual behaviours in this group can range from men who usually have sex with women but who occasionally have sex with men, to men who are almost exclusively behaviourally homosexual. Sometimes sex between men or certain types of sexual activity like mutual masturbation are defined as playing or not perceived to be real sex. In some cultures or in some male only environments sexual identity might be defined by role during penetrative sex mirroring attitudes around heterosexual sex. Other reasons for not identifying as gay or bisexual include internalised homophobia. There are also men who are 327 situationally homosexual in male only environments or institutions where female partners are unavailable, in prisons for example. Not all male escorts or rent boys (that is, men who sell sex to men) identify as gay or bisexual. The examples above present situations where the health adviser needs to be extremely sensitive to the personal circumstances of the patient. Men who have sex with men but who do not identify as gay or bisexual are frequently wary of disclosing their sexual activity with men to medical staff. This can also be true of gay or bisexual men who are just starting to explore their sexuality and men who are new attenders at your clinic. They might be anxious about how they will be treated by medical staff if they disclose their true sexuality. Some men might describe male partners as female or not mention male partners in a consultation. This is more likely to happen if the doctor, health adviser or nurse does not specifically ask a patient if he has or has ever had male partners ? Following the Wolfenden report gay sex was only partially decriminalised under the sexual offences act of 1967. Definitions of what constitutes private or public space continue to be open to interpretation and legal debate. In November 2000 the government invoked the Parliament Act to force through legislation to make the age of consent 16 in England, Scotland and Wales and 17 in Northern Ireland. There has been recent discussion at government level on changing the law on gross indecency to a new offence of public indecency. If this happens it will effectively end the legal discrimination against gay men inherent under the existing law. The content of your interview with your patient/client will of course depend upon his knowledge base and needs. Working with someone just beginning to explore his sexuality can be very different to working with someone who is sexually experienced. The following areas for discussion will depend upon why he has been referred to the health adviser or has requested to see the health adviser and should be tailored to the needs of the patient. The interview As with any patient, in order to establish trust and confidence it is first important to find out what he may already know, what he percieves his needs to be and to build on these. A key part of the health adviser role is to provide the patient with the information necessary for him to make informed choices about his sexual wellbeing. This means addressing gaps in the patient s knowledge and challenging any assumptions not based on fact or evidence. This will guide the patient towards developing a personal sexual risk reduction strategy that makes sense and is workable for him.

If he is given preferential treatment he may be more inclined to co-operate with partner notification and encourage associates to use the service purchase 500 mg biaxin otc. She has no other symptoms generic 250 mg biaxin amex, and is not therefore in need of urgent medical attention 250 mg biaxin mastercard. The argument for asking her to return for the next available appointment might be that she does not have a right or a need to be seen that day, and it would be unfair to others if the triage protocol were not followed for everybody. On the other hand, it may seem unfair to turn her away when she has made an arduous journey in good faith. Her social circumstances may make it difficult for her to return in the near future, and the opportunity to treat a potential infection could be lost, or delayed. She may be turned away because she does not fit the triage criteria that should, in fairness, apply to all. Some may feel that she does not deserve preferential treatment because she has been uncooperative in the past, and should not receive priority over patients who wait for appointments and keep them, without fuss. There could be a concern that, by seeing her on demand, the service is rewarding bad behaviour and discouraging her from developing a more constructive approach to health services. An alternative view would be that she is disadvantaged by an appointment system because of her poor capacity to organise her life and grasp the rules of service use. If the service is, in effect, less accessible to her than others, there is a sense in which it is fair to make allowances and give her access on the terms she can manage. The only sure way of preventing her from developing complications or transmitting infection to others is to see her straight away. It does not cause serious morbidity if left untreated for a short time, and it is not normally sexually transmitted. However, the unpleasant odour associated with the condition can be embarrassing and distressing. Effective and ethical health care requires a holistic approach, where due consideration is also given to psychological, social and economic needs. She does not have any symptoms, but has had unprotected sex with a 25-year old man who has other regular partners. Firstly, she has been at risk of infection; secondly, she may find it difficult to be absent from home or school without explanation to return at a future time; thirdly, child protection issues need to be explored further. There is also the importance of first impressions, because attending a clinic for the first time requires courage. The apprehension and embarrassment that many patients feel during a first visit may be more acute for the very young. If the girl is turned away she may find it difficult to come back, and may share her unsatisfactory experience with friends, who may also be discouraged from using the service. To use skills to convey complex information and allow patients to explore emotional responses that might obstruct absorbing 2 information or achieving sexual well being. These are: Sexual health is the primary focus of counselling in health advising work The type and level of counselling used depends on patient need Even information giving depends on the use of counselling skills There is a time frame that has to be worked within 104 Counselling, or using counselling skills? All health advisers use counselling skills, which they bring from their respective professional backgrounds, and develop further in their clinical practice. Those with appropriate professional training and supervision are well placed to perform an enhanced role by offering time-limited counselling to suitable patients. Health advising sometimes deploys a specialised form (or a number of specialised forms) of counselling, but always makes use of counselling skills in the support of other aspects of the role. Counselling skills are fundamental There are five core roles of health advising and counselling skills are fundamental to all of them. In the counselling field generally, there is an increased emphasis on time-limited approaches. Some studies suggest that the therapeutic effectiveness of time-limited work is 4 indistinguishable from long-term, or more open-ended, work. Findings included the following: Most significant therapeutic change happens early on in therapy - 62% of patients are 5 helped within 13 sessions Patients are less likely to drop out of therapy or counselling when a time constraint is 6 applied (this is particularly true of younger patients) Therapists estimates exceeded patients of the number of sessions needed by a factor 7 of 3 to 1 8 78% of patients getting only one session thought they had benefited. This is particularly important when evaluating the effectiveness of crisis intervention counselling. Positive changes can continue to be made by the patient after the intervention 106 Applying a time-limited approach to health advising A number of principles need to be borne in mind when doing this kind of work. Health advisers have to prioritise the interventions they can use within the constraints imposed by their workload and clinical setting. Some may have an affinity, and the necessary professional training for doing longer-term work, but it is practically and ethically more important that as many people as possible are to be offered the help they need. Where there is some room for compromise (some flexibility in the length of interventions that health advisers can offer to particular patients), this will help with developing skills, maintaining morale, and targeting particular interventions to meet particular needs. Practitioners can be adversely affected by exposure to purely one-off work, especially if they have inadequate support and supervision. Some patients do benefit from ongoing work of a sporadic kind, and health advisers sometimes assume a casework role when this happens. Methodology of time-limited counselling Time-limited approaches are not there to reconstruct the personality and although some personal growth may result, that is not the sole aim. It is also important that the patient believes that the practitioner can help them. Conversely the practitioner needs to establish that an intervention is appropriate, and therefore, accurate assessment is essential. It is important to engage with the patient quickly and form a good working alliance. Health advisers work at putting the patient at their ease through demeanour, dress and a relaxed manner, and by explaining their role. An effective working relationship depends on the establishment of trust, and this in turn partly rests on a realisation of the importance of confidentiality.
