Instead, the clinician to identify changes in sexual function status or new should aim to educate the patient as fully as possi- medical conditions, and to offer continuing education ble, making full use of evidence-based literature and and support to patients and their partners. Also, in patients who have more gradual or limited dysfunction should not be delayed or postponed treatment response, such as those who are re-estab- as most patients desire immediate treatment. Health care providers should seek, receive and impart information related to sexuality. Individuals have the right to receive the highest attainable stan- dard of sexual health, including access to sexual and reproductive health care services as a fundamental sexual right. Sexual dysfunctions may have major impact on quality of life and psychosocial and emotional well being. The three principles for clinical evaluation and management of sexual dysfunctions are: a) adoption of a patient-centered framework, with emphasis on cultural competence in medical practice; b) applica- tion of evidence-based medicine in diagnostic and treatment planning; c) use of a uniied management approach in evaluating and treating sexual problems in both men and women. Therefore, diagnostic tests or procedures should not be recommended without controlled clini- cal data or research evidence supporting their use. Ignorance and knowledge gaps about sexual function and dysfunction are commonplace. Misin- formation or myths may lead to uninformed sexual decisions with serious consequences.

A number of pumps specifically designed for drug infusion are now available muscle relaxer jokes discount azathioprine 50mg line, and these often combine many of the desirable features listed above (Fig muscle relaxant new zealand buy cheap azathioprine 50mg on-line. As with other anaesthetic apparatus muscle relaxant voltaren discount 50mg azathioprine otc, it is helpful to muscle relaxant succinylcholine buy discount azathioprine 50 mg online obtain potentially suit able infusion pumps on a trial basis, to ensure that they have all of the features required, and prove reliable during routine operation. Whichever method of infusion is used, initial adjustments to the infusion rate will be required after induction of anaesthesia, but once experience has been gained with a particular anaesthetic technique, stable infusion rates and depth of anaesthesia can be established relatively rapidly. Initially the infusion rate should be based on the pharmacokinetics of the anaesthetics used, although it must be appreciated that even when full details of these have been published for a par ticular species, considerable between-animal variability will occur. Nevertheless, if the drug has been well-characterized, then the required infusion rate can be estimated from its volume of distribution (the theoretical space in the body avail able to contain the drug) and its rate constants (Mather, 1983). If a particular concentration of dye is needed in a sink filled with water, the con centration of dye needed to be added is equal to the volume of water in the sink multiplied by the target concentration. If the sink’s taps are turned on, and the plug is pulled out, then the situation becomes more complicated. In these circum stances, dye must be added continuously to maintain the desired concentration. These same considerations apply to continuous intravenous infusion of anaesthetics. If anaesthetic is infused at a constant rate, eventually the rate of removal from the plasma will equal the rate of infusion. Under these circumstances: Maintenance infusion rate Clearance Plasma concentration Unfortunately this is an oversimplification for many anaesthetics, as their kinet ics are better described by more complex models than a single sink, or single compartment. Many intravenous anaesthetics are characterized by one compart ment with rapid distribution and elimination, and one or more compartments with slower equilibration and elimination times. The rapid distribution compartment is often thought to represent the blood and other well-perfused tissues. Drugs with these characteristics will have a single rapid half-life, and one or more slower half-lives. These are calculated from the rate of fall of the plasma concentration after administration of a single intravenous dose of the compound. The half-life of a compound is the time taken for its plasma concentration to fall by 50%. If the anaesthetic is infused at a constant rate, it will require 4–5 half-lives to achieve a steady state. The more usual alternative is to administer an initial load ing dose to induce anaesthesia, followed by a constant infusion. The problem 126 Labora to ry Animal Anaesthesia with this latter technique is that if the drug’s pharmacokinetics are best repre sented by a multicompartment system, then the plasma concentration will fall rapidly as redistribution to other compartments occurs. If additional anaesthetic is given rapidly to compensate, then dangerously high plasma levels can be attained. One method of estimating the loading dose required to achieve a steady plasma concentration rapidly has been described by Norwich (1977) as: Half-life Loading dose Maintenanceinfusion rate 0 693. The slow half-life is used with anaesthetics modelled using multicompartment systems. This method can result in high plasma concentrations, so if the required loading dose exceeds the recommended safe induction concentration, a safer approach is to multiply the maintenance rate by the half-life of the anaesthetic. This would prolong the time taken to reach a steady state, but would reduce the chance of overdose. An alternative approach is to use two infusions, an initial rapid rate followed by a slow maintenance rate, with the rates determined by the drug clearance and the half-life (Wagner, 1974; Musk et al. If the half-life of the drug is not known, but practical experience has been gained by giving intermittent injections of the anaesthetic to maintain anaesthe sia, then the to tal quantity of drug given in a specific time period can be used to estimate an infusion rate. It may also be possible to extrapolate half-lives of anaesthetics between species, as has been suggested for antibiotics, using the relationship of body weight 0. After establishing an infusion rate, it may be necessary to dilute the anaes thetic to provide a volume that can more easily be controlled using an infusion pump. In theory, many pumps are capable of delivering very low volumes, but the actual rates, especially when using plastic syringes, may vary, as the plunger in the syringe may not move smoothly and continuously in response to the pump. Increasing the volumes that are being infused may help provide more stable infu sion rates. However, care must be taken not to infuse to o much fluid, especially in smaller animals. As a general guide, infusion rates should not exceed 10–15% of the animal’s blood volume each hour. Injectable Agents – Use of Long-acting Anaesthetics An alternative to administering repeated doses or a continuous infusion of short acting agents is to select an anaesthetic with a very prolonged duration of action. Urethane Urethane has been widely used for the production of long periods of anaesthe sia in a range of labora to ry species, although its mechanism of action remains uncertain (Hara and Harris, 2002). It is reported to cause minimal depression of the cardiovascular and respira to ry systems (Buelke-Sam et al. It should be noted, however, that this cardiovascular stability is in part due to sustained sympathetic nervous system activity, associ ated with high circulating levels of adrenaline (epeinephrine) and noradrenaline (norepinephrine) (Carruba et al. Although respira to ry function is usually stable, problems of airway patency can arise, especially in small mammals and intubation and ventilation may be required (Moldestad et al. The proper ties and effects of urethane have been extensively reviewed elsewhere (Maggi and Meli, 1986a, b and c). Urethane has been reported to be both mutagenic and carcinogenic (Field and Lang, 1988) and although the experimental studies on its potency are somewhat limited, it is now widely regarded as a potential hazard to staff. Before using urethane it is suggested that other anaesthetics are assessed and an alternative regime is used whenever possible. If it can be shown that the use of other anaes thetics would frustrate the purpose of the experiment and a decision is taken to use urethane, it is recommended that it be treated as a moderate carcinogen. In most institutes there will be guidelines for the safe handling of such materials and these will usually include the use of gloves and face masks when handling the substance and use of fume cupboards or similar cabinets for preparing solu tions from the dry powdered drug. If such precautions are adopted, urethane can be used in a reasonably safe manner and is a valuable anaesthetic for providing long-lasting, stable surgical anaesthesia. In view of its carcinogenic action in rodents, it seems inadvisable to allow animals to recover from urethane anaesthesia. Although classed as a long-acting anaesthetic, urethane’s duration of action can vary considerably, and it also causes peri to neal effusions when administered intraperi to neally. An alternative approach is to lightly anaesthetize the animal with a volatile anaesthetic, place an intravenous catheter and administer urethane by this route (Millar et al. Chloralose When prolonged anaesthesia is required and surgical interference is to be kept to a minimum, chloralose may be used. This drug is a hypnotic and has little analge sic action, although this varies considerably between different species and strains of animal and in some individuals surgical anaesthesia is produced (Luckl et al. It is usually necessary to administer a short-acting anaesthetic, such as pro pofol while carrying out any surgical procedures, following which chloralose can be administered to produce long-lasting, light anaesthesia. This drug is believed to be particularly valuable for studies of the cardiovascular system, since the vari ous au to nomic reflexes are well maintained (Holzgrefe et al. Chloralose is prepared by heating the powdered drug in water at 60° C to form a 1% solution. Care must be taken to avoid boiling the drug and the solu tion must be cooled to 40° C before administration. Administration in propylene glycol improves solubility and is claimed to reduce problems of acidosis associ ated with administration of chloralose (Shukla and Shukla, 1983). A more stable 128 Labora to ry Animal Anaesthesia solution can also be produced using cyclodextrin (S to rer et al. The onset of action following intravenous administration is about 15minutes, so even if surgical procedures are not to be undertaken, it is preferable to administer a short-acting drug to induce anaesthesia, followed by the chloralose. Chloralose is normally used only for non-recovery procedures, because of the prolonged recovery time. In addition to the use of chloralose as the sole anaesthetic, various combina tions with urethane have been described, which aim to reduce the quantity of urethane required, and provide improved analgesia in comparison to chloralose alone (Korner et al. These combinations do not, of course, circumvent one of the main difficulties of using urethane, its classification as a carcinogen.

Effects on Gastrointestinal Microbial Ecology Decreased gastric acidity due to any means including pro to n pump inhibi to rs, increases gastric counts of bacteria normally present in the gastrointestinal tract. Treatment with pro to n pump inhibi to rs may lead to slightly increased risk of gastrointestinal infections such as Salmonella and Campylobacter and, in hospitalized patients, possibly also Clostridium difficile. By the second year the difference between treated and control rats was much smaller (46% vs 26%) but still showed more hyperplasia in the treated group. For this strain of rat no similar tumor has been noted his to rically, but a finding involving only one tumor is difficult to interpret. In a 52-week to xicity study in Sprague-Dawley rats, brain astrocy to mas were found in a small number of males that received omeprazole at dose levels of 0. In a 2-year carcinogenicity study in Sprague-Dawley rats, no astrocy to mas were found in males or females at the high dose of 140. A 78-week mouse carcinogenicity study of omeprazole did not show increased tumor occurrence, but the study was not conclusive. Omeprazole was positive for clas to genic effects in an in vitro human lymphocyte chromosomal aberration assay, in one of two in vivo mouse micronucleus tests, and in an in vivo bone marrow cell chromosomal aberration assay. Omeprazole at oral doses up to 138 mg/kg/day in rats (about 56 times the human dose on a body surface area basis) was found to have no effect on fertility and reproductive performance. Two studies (1 and 2) were conducted in patients with an active duodenal ulcer, and the other study (3) was conducted in patients with a his to ry of a duodenal ulcer in the past 5 years but without an ulcer present at the time of enrollment. The combination of omeprazole plus clarithromycin plus amoxicillin was effective in eradicating H. Additionally, if patients dropped out of the study due to an adverse event related to the study drug, they were included in the analysis as failures of therapy. The impact of eradication on ulcer recurrence has not been assessed in patients with a past his to ry of ulcer. Studies 6 and 7 were conducted in Europe and enrolled 154 and 215 patients, respectively. In the per-pro to col analysis, the following patients were excluded: dropouts, patients with missing H.

For patients with ulcer size greater than 1 cm, 40 mg was significantly more effective than 20 mg at 8 weeks. In a foreign, multinational, double-blind study of 602 patients with endoscopically diagnosed gastric ulcer, omeprazole 40 mg once daily, 20 mg once daily, and ranitidine 150 mg twice a day were evaluated. Complete daytime and nighttime heartburn relief occurred significantly faster (p < 0. Results to determine maintenance of healing of erosive esophagitis are shown below. The table below provides the results of this study for maintenance of healing of erosive esophagitis. Doses ranging from 20 mg every other day to 360 mg per day maintained basal acid secretion below 10 mEq/hr in patients without prior gastric surgery, and below 5 mEq/hr in patients with prior gastric surgery. However, in some patients serum gastrin increased to levels greater than those present prior to initiation of omeprazole therapy. Seventy-five percent (9/12) of the patients had vomiting/regurgitation episodes decreased from baseline by at least 50%. Patients were administered a single dose of omeprazole (10 mg or 20 mg, based on body weight) for 4 weeks either as an intact capsule or as an open capsule in applesauce. Successful response was defined as no moderate or severe episodes of either pain-related symp to ms or vomiting/regurgitation during the last 4 days of treatment. Results showed success rates of 60% (9/15; 10 mg omeprazole) and 59% (58/98; 20 mg omeprazole), respectively. Healing of Erosive Esophagitis In an uncontrolled, open-label dose-titration study, healing of erosive esophagitis in pediatric patients 1 to 16 years of age required doses that ranged from 0. Erosive esophagitis was healed in 51 of 57 (90%) children who completed the first course of treatment in the healing phase of the study. In addition, after 3 months of treatment, 33% of the children had no overall symp to ms, 57% had mild reflux symp to ms, and 40% had less frequent regurgitation/vomiting. Maintenance of Healing of Erosive Esophagitis In an uncontrolled, open-label study of maintenance of healing of erosive esophagitis in 46 pediatric patients, 54% of patients required half the healing dose. In addition, maintenance therapy in erosive esophagitis patients resulted in 63% of patients having no overall symp to ms.

Despite this theoretical risk, only one case report of an endometrioid adenocarcinoma exists in the literature. This recommendation may also be unrealistic since transgender men report avoiding gynecologic care due to lack of cultural competency among providers. Unexplained vaginal bleeding (in the absence of missed or changed dosing of tes to sterone) in a patient previously with tes to sterone induced ameorrhea should be explored (Grading: X C M). Transgender men should be educated on the need to inform their provider in the event of unexplained vaginal bleeding. Hysterec to my for primary prevention of endometrial cancer is not currently recommended (Grading: X C M); consideration of hysterec to my for the purpose of eliminating the need for cervical cancer screening may be discussed on a case-by-case basis, in recognition of the role of hysterec to my in reducing gender dysphoria, and in consideration of surgical risks and irreversible infertility. Ovarian cancer While there have been several case reports of ovarian cancer among transgender men,[5,6] there is no evidence to suggest that trans men on tes to sterone are at increased risk. Transgender men should receive the same recommended counseling and screenings for anyone with ovaries based on his to ry and presentation. While a unilateral or bilateral oopherec to my may be performed in transgender men as part of the management of gender dysphoria or for a pathologic process, routine oopherec to my in for primary prevention of ovarian cancer is not recommended.

Mental health considerations with transgender and gender nonconforming clients Primary authors: lore m. Due to pathologization and mistreatment by mental health professionals, transgender people are often reluctant to engage with mental health providers. Every intake for care should include a mental health his to ry and an assessment for active mental health concerns. Screening should include primary mental health problems, environmental and social stressors, and gender-related needs. Screening also requires provision of appropriate referrals to transgender-affirming mental health services when needs are identified. Mental health concerns endorsed by a patient should not be au to matically assumed to be related their gender identity. While some may be seeking specific assistance for gender-related themes, others are seeking assistance with depression, anxiety, or other clinical concerns unrelated to their gender identity. In a recent publication, Machtinger and colleagues describe a theoretical framework for providing trauma-informed primary care. The model proposes the need to address the primary care environment, patient screening, provider response to the patient’s needs, and a foundation of organizational values that support trauma informed care across all levels of the organization. Machtinger and colleagues address the need for confidential spaces in which to conduct a thorough screening of a patient’s his to ry with a special emphasis on trauma and a patient’s response. June 17, 2016 118 Guidelines for the Primary and Gender-Affirming Care of Transgender and Gender Nonbinary People Primary mental health needs of transgender people Transgender and gender nonconforming people, in general, have three types of need for mental health. This includes determining exactly what one’s gender identity is, coming to terms with this gender identity, self-acceptance and individuation, and exploring individual – level ways to actualize this identity in the world. This may also include preparation and assessment for various gender-affirming treatments and procedures. This includes coming out to family, friends, and coworkers, dating and relationships, and developing to ols to cope with being transgender in a sometimes transphobic world. The age at which this realization occurs, and the age at which treatment is initially sought, may vary greatly from one person to the next. It should not be assumed that arrival at this realization or seeking treatment late in life indicates that an individual is any “less” transgender. Due to the nature of social and medical transitions, a transgender person must come out to people with whom they interact unless they relocate and choose to live “in stealth”. This process can be gender-affirming when transgender people are supported in doing so. Conversely, a lack of support or experiences of being mistreated, harassed, marginalized, defined by surgical status, or repeatedly asked probing personal questions may lead to significant distress. Approaches to supporting transgender people during the coming out and exploration process include reinforcing self-identification, and exploration of and integration of individualized identity. This in turn will provide a supportive foundation for interacting with unsupporting partners, friends, relatives or coworkers, as well as provide needed to ols to diffuse and deflect potential implicit and unconscious transphobic messaging and rejection in every day life. Transgender people experience the background rates of common mood disorders, bipolar disorder, schizophrenia etc. Routine primary care visits should include screening for co-occurring mental health conditions, past treatments, and his to ry of suicide and self-injurious behaviors, symp to ms of posttraumatic stress, and substance use. Primary care providers should be equipped to handle basic mental health needs of transgender patients. Any primary mental health concerns beyond the scope of the provider’s routine practice should be referred to transgender-affirming mental health providers. Referrals should be made when appropriate to substance abuse treatment programs, including dual diagnosis programs for those with co-occurring mental illness. All primary care offices should have a clear suicide response plan for any patient endorsing thoughts of suicide. Trans Lifeline is a crisis hotline staffed by and for transgender people and can be included in safety planning with patients. Transgender patients should not be placed in the position of training their providers about their mental or physical health care needs. Environmental and social considerations Environmental and social stressors greatly impact mental health. Transgender people are more likely to live in poverty, be discriminated against in employment, and be victims of violence than non-transgender people. Transgender people with intersecting identities such as race, ethnicity, or socioeconomic status face increased likelihood of adverse life events. Transgender women of color face extraordinarily high rates of social and health disparities.

Patients with hypercalcaemia are usually volume deplete, and this should be corrected. Hypercalcaemia can occur as a result of reduced excretion, increased absorption or a shift of calcium between body compartments. Common causes are primary hyperparathyroidism, thiazide diuretics and malignant disease. Rarer causes include sarcoidosis, thyro to xicosis, vitamin D in to xication, calcium-containing drugs and cortisol deficiency. Consider giving furosemide (40-80mg orally or iv), to increase urine flow and calciuresis. If diuretic is given it is essential that the patient is not rendered hypovolaemic. If the serum calcium is still raised after 24 hours give iv pamidronate over 2-3 hours in a dose of 15-90mg (15-30mg if serum calcium up to 3. The serum calcium should fall within 24-48 hours with the maximum response taking 4-5 days. Where hypercalcaemia is due to hyperparathyroidism associated with renal disease, surgical parathyroidec to my or medical parathyroidec to my, using Cinacalcet may be considered and advice from the renal team sought. Although the definition of hyponatraemia is Na <135mmol/L, it is only 79 clinically significant if the sodium concentration is <125 mmol/L, or has fallen rapidly (>20 mmol/L in 24 hours). Hyponatraemia can lead to shift of H2O in to cells, with cell swelling and an increase in intracellular fluid ie cerebral oedema. The concentration of plasma sodium does not give any indication of volume status, i. The combination of hyponatraemia and normal or elevated plasma osmolality indicates the presence of an additional, osmotically active, substance. Osm (mmol/kg) = (2 x serum [Na]) + (serum [glucose]/18) + (blood urea nitrogen*/2. Clinical management depends on type of hyponatraemia: Hypovolaemic hyponatraemia: give iv 0. Hypervolaemic hyponatraemia: restrict fluid to 1L/day restrict sodium intake give diuretic as necessary + replace K loss treat underlying disease Hyper to nic saline should be reserved for patients with seizures or other life-threatening neurological complications of hyponatraemia. The symp to ms of hypernatraemia range from mild confusion to coma, and can occasionally be associated with intracerebral or subarachnoid + haemorrhage. Depending on the cause this may involve giving an anti-emetic, s to pping diuretics or treating diarrhoea 2. In the first 24 hours replace one third of the calculated water deficit and maintain usual fluid replacement. Many patients have a personal management pro to col which is kept in a file in their name in A&E Majors. The pain may be localised to a single long bone, present symmetrically in several limbs, or involve the axial skele to n (lumbar spine, ribs or pelvis). Pain can lead to behavioural changes including becoming non-communicative or occasionally panicked and aggressive. If pain is bad enough to bring the patient to hospital, the patient usually warrants admission. Patients will often have tried a variety of analgesics at home including some form of opiate. Antibiotics can be given orally unless clinical concern warrants intravenous administration. No patient admitted with sickle cell crisis should be placed on a ward outside the Medical Service Centre there are specific cohorted sickle beds. After admission to the ward continue 2 hourly sc morphine or analgesia regimen prescribed. Infection Patients prone to sickling have reduced splenic function and are at risk of overwhelming septicaemia (pneumococcus, meningococcus, rarely haemophilus) even if taking penicillin prophylaxis. Splenic or Liver Sequestration During infection children may suffer a rapid fall in haemoglobin and growth of the spleen – changes often noted by the mother. In adults, liver sequestration is more common and can present similarly with profound anaemia and hepa to megaly. Chest crisis Severe shunting & hypoxia caused by intra-pulmonary sickling and mimicking pulmonary embolus/pneumonia, may start in one lobe and then spread to others. Treat with fluids and oxygen; observe arterial O2 tensions – a falling PaO2 will require exchange transfusion and needs expert advice. Encourage patients with chest pain to attempt one maximal inhalation every 5-10 mins (‘incentive spirometry’) to aerate basal lung segments; this reduces the risk of progressive sickle chest syndrome. Non invasive respira to ry support may well be required, as well as urgent exchange transfusion. Girdle syndrome If sickling occurs in the splanchnic bed, abdominal pain with rigidity, loss of bowel sounds and increasing icterus may develop. A surgeon should be consulted to exclude other abdominal events, but surgery should be withheld unless unavoidable, and then only after exchange transfusion and discussion with haema to logists. Cerebral sickling Patients can present with strokes, fits, coma, bizarre behaviour or psychosis, and sickling should be excluded in any susceptible patient with such signs. Major or prolonged attacks post puberty can result in permanent loss of erectile function. Urgent referral to Urology is essential as early decompression can be achieved by aspiration +/ intracavernosal phenylephrine. Blood transfusion In a patient with Sickle Cell Disease blood transfusion can be dangerous. Never give a simple transfusion for anaemia (except in those sequestrating), without reducing HbS level by exchange. If this precaution is not taken the blood viscosity will increase and make the patient worse. Get haema to logical advice and ensure that the blood transfusion department knows that the patient due to receive blood has sickle cell, so that appropriately phenotyped blood can be provided. Surgery Do not plan or carry out surgery without first assessing the patient with the Haema to logy Team. Special pre and post-operative care, often including blood exchange, is essential to optimise outcome. Intravenous fluid replacement is important (minimum of 3 litres/24 hours) and ensure nephro to xic drugs are withheld. It is important to identify underlying causes of agitation (See Step 1) before using drug treatment. Minimise polypharmacy, avoid routine sedatives (including sleeping tablets) and review medication every 24 hours fi Benzodiazepines should be used first line unless contra-indicated. Risks with benzodiazepines include loss of consciousness, respira to ry depression or arrest. Subsequent Steps 2-5 will depend on the patient’s age (ie above or below 65 yrs old). If the nurse or other clinician is concerned about the patient’s physiological status, whether the patient requires treatment with medication, or is to be physically restrained, the patient’s care must be escalated to a senior doc to r and nurse. Assessing capacity fi Establish what motives the patient has and compare this with what the clinician wants or is trying to achieve. Make sure the patient is given information necessary to make a decision 86 fi Be clear if you are treating a consenting patient, or giving the treatment in best interests under the Mental Capacity Act fi Consider the need for restraint if a patient who does not have capacity is displaying behaviour that is putting themselves or others at risk of harm. Should medication be required, ensure the patient is moni to red according to the pro to col below. Use of flumazenil • Flumazenil (a benzodiazepine antagonist) must be given if the respiration rate falls to <10/minute after a benzodiazepine has been used • Give flumazenil 200micrograms intravenously over 15 seconds. If the desired level of consciousness is not obtained within 60 seconds, a further 100micrograms can be injected and repeated at 60-second intervals to a maximum to tal dose of 1mg (1000micrograms) in 24 hours (initial dose plus 8 further doses). Use of anticholinergics • An anticholinergic medicine may be given to counteract an acute dys to nic or parkinsonian reaction. Maximum dose is 30mg/24hrs Maximum recommended doses • Other medicines prescribed for the patient must also be considered (especially regular prescriptions for antipsychotics or benzodiazepines) • these maximum doses must not be considered a license to use more than the minimum effective dose, they are provided purely for guidance and do not replace the need for careful clinical judgement by the staff caring for the patient. Doses can be borrowed ‘out of hours’ from any adult Critical Care Unit but must be documented on the ‘Drugs Lent Out’ form.
