There is now evidence that the incidence of head and neck cancers is increasing amongst young people of both sexes. This guideline will be of interest to all healthcare professionals working with patients with head and neck cancers, including ear, nose and throat specialists, oral and maxillofacial surgeons, plastic surgeons, general surgeons, clinical oncologists, nurses and allied health professionals. The ultimate judgement must be made by the appropriate healthcare professional(s) responsible for clinical decisions regarding a particular clinical procedure or treatment plan. A percentage of patients will not have the traditional risk factors, but the absence of these risk factors does not preclude the diagnosis. A small cohort study comparing smokers, ex-smokers and non-smokers showed that smoking alters gene expression in bronchial epithelium cells. Two years after discontinuation of smoking 2++ all but 13 of the 97 genes reverted to normal expression levels. D Healthcare professionals should put people in contact with the appropriate alcohol counselling service. A high intake of red meat, processed meat and fried food increases the risk of pharyngeal, 2+ laryngeal and oral cancer. A questionnaire of awareness of signs and symptoms 1+ and risks of oral cancer showed that all those who received the leafet (smokers, non-smokers and past smokers) reported greater knowledge (p< 0. Autofuorescent endoscopy, if performed, must be carried out by an experienced operator, and should be complementary to microlaryngoscopy and/or white light endoscopy, rather than a 3 replacement for them. For tumours confned to the mucosa, direct endoscopy is more accurate than cross-sectional imaging. Five showed that for oropharyngeal tumours, Hpv infection was associated with younger age, absence of additional risk factors (such as smoking and alcohol consumption), high proliferation indices, 2+ high grade, basaloid subtype, better response to radiotherapy and a better survival. Modifed radical neck dissection As for radical neck dissection with preservation of one or more nonlymphatic structures. The lymph node groups removed are based on patterns of metastases which are predictable for each site of the disease. No randomised controlled evidence was identifed defning a threshold of risk over which prophylactic treatment of the neck is required. A study of computer assisted decision analysis, using data from retrospective series, suggested that prophylactic treatment of the neck is required if the risk of occult nodal metastases rises 3 above 20%. There is a body of evidence from retrospective studies suggesting that in patients who do not have prophylactic therapy of the clinically N0 neck there is often a low salvage rate on disease recurrence. In patients with hypopharyngeal cancers, local control was signifcantly better with radiotherapy compared to surgery. No randomised controlled evidence was identifed that clearly defnes the best treatment for patients with a clinically node positive neck. If the involved nodes are fxed and unresectable, radiotherapy or chemoradiotherapy may be the only therapeutic option. Retrospective data suggest that there is an increased risk of local recurrence following neck dissection if histological examination reveals any single node greater than 3 cm in size (N2) or 3 two or more positive nodes. Neck node size and fxity predict response rate and local control with radiotherapy alone. There are several different systems used for grading radiotherapy side effects (toxicities) caused by irradiation of normal tissues. Studies of hypofractionated radiotherapy have been mainly confned to the treatment of patients ++ 1 with glottic cancer. There is a body of evidence demonstrating a survival advantage when chemotherapy is administered concurrently with radiotherapy and the majority of this relates to conventionally fractionated radiotherapy (see section 8). A randomised trial comparing hyperfractionated accelerated radiotherapy (total dose 70. Evidence supporting the use of brachytherapy comes from large case series from centres experienced in the technique. The fve-year local control rate for patients following interstitial brachytherapy for T3 oral cavity tumours is 49-70%. There is no clear evidence to determine whether local control in oropharyngeal cancer treated with a brachytherapy boost following external beam radiotherapy is better than with external beam radiotherapy alone. D Patients with small accessible (T1/2) tumours of the oral cavity and oropharynx may be treated by interstitial brachytherapy to a dose of 65-70Gy at a dose rate of less than 0. Without longer follow up, the protective effect of amifostine on the tumour is unclear. Vomiting is signifcantly increased with amifostine compared to control, but hypotension and nausea are not. A Pilocarpine (5-10 mg three times per day) may be offered to improve radiation-induced xerostomia following radiotherapy to patients with evidence of some intact salivary function, providing there are no medical contraindications to its use. There is no evidence to suggest that washing during radiotherapy increases acute radiation skin toxicity. The open approach uses facial splits and incorporates skeletal osteotomies so that the tumour can be widely exposed. The wide variety of surgical techniques now available for head and neck tumour surgery demands a multidisciplinary approach with surgeons experienced in several techniques. For squamous carcinoma of the oral cavity,101,273-275 and larynx,276 evidence suggests that the presence of positive margins leads to locoregional recurrence. In 3 oropharyngeal and hypopharyngeal tumours, there is some evidence that margins may be as important as T stage and N stage for predicting recurrence (all p<0. This may leave a major physical defcit that cannot be repaired by primary mucosal closure or skin grafting. No randomised controlled evidence was identifed comparing the outcomes of different techniques. The evidence is from retrospective case series, mainly relating to intraoral and hypopharyngeal tumours. Free fap transfer is a safe and reliable technique for reconstruction in patients with head and neck cancer in general, and particularly for oral cavity and hypopharyngeal cancer. No good quality randomised controlled trials examining the role of adjuvant radiotherapy in combination with surgery were identifed. The risk of recurrence increases as the number of histologically positive nodes increases. Locoregional control signifcantly decreases in the presence of two or more histological indicators 295,296,305 3 of poor prognosis. Retrospective subgroup analysis shows that this beneft is greatest in those patients with extracapsular extension and/or positive surgical margins. A In patients with extracapsular spread and/or positive surgical margins, who are medically fit, postoperative concurrent chemoradiotherapy with single agent cisplatin and conventionally fractionated radiotherapy should be considered. The absolute survival beneft at fve years for concurrent ++ 1 single agent cisplatin as opposed to all other drugs is 11%. The reduction in risk of death has been calculated for each subsite (see Table 4). Most acute toxicity and late toxicity data relate to chemoradiation with conventionally fractionated radiotherapy. There is no evidence to support the use of neoadjuvant or adjuvant chemotherapy in combination with surgery alone. A single agent cisplatin is recommended as the chemotherapeutic agent of choice in concurrent chemoradiotherapy. A Neoadjuvant cisplatin/5Fu followed by radical radiotherapy alone may be used in patients with locally advanced resectable hypopharyngeal cancers who have a complete response to chemotherapy. A the routine use of adjuvant chemotherapy following radiotherapy is not recommended. A the routine use of neoadjuvant or adjuvant chemotherapy in combination with surgery is not recommended. Radiotherapy was either conventionally fractionated, hyperfractionated or accelerated. No randomised controlled trial has compared chemoradiotherapy with and without concurrent cetuximab administration. Disease-free survival following salvage therapy decreases with increasing stage of recurrence. Quality of life following salvage correlates 3 with the stage but not site of the recurrence. This assumes that the recurrent disease can be encompassed in a reasonable treatment volume. In patients with small, early (T1N0 and T2N0) recurrences or new primaries in previously irradiated oropharynx, interstitial brachytherapy alone (60Gy) can result in a fve-year local 3 control rate of 69-80%,336,337 with a fve-year overall survival of 30%, most deaths being due to causes other than the cancer. Several small series of highly selected patients reported fve-year survival ranges from 9-20%338-342 and local control rates of 11-48%. Centres must be experienced in the recognition and management of acute and late radiation toxicity. There are no randomised controlled comparisons of symptomatic beneft and quality of life achieved with differing palliative chemotherapy regimens. There is no evidence that combination chemotherapy improves survival compared to treatment with single agents.

In contrast to understanding of mouse development spasms right side of body purchase mefenamic 500 mg visa, much less is known about the cellular and molecular events of blastocyst formation in human embryos muscle relaxant glaucoma order 500mg mefenamic mastercard. Some experiments on the timing of cell-lineage restriction have been performed muscle relaxant m 751 buy mefenamic with american express, but not with as much precision as in mice because of the restricted number of embryos that are available for research spasms falling asleep discount 500 mg mefenamic with visa. Compounding the challenges of studying development in human embryos has been the absence of appropriate methods spasms in lower abdomen order mefenamic 500mg fast delivery. The early postimplantation stages of mouse and human development differ morphologically and perhaps in other ways not currently understood muscle relaxant kava buy mefenamic 250 mg free shipping. Current data suggest that cell-lineage restriction occurs later in a human embryo than in a mouse embryo, probably not until after the blastocyst is fully developed. New technologies for analyzing gene expression in small amounts of tissue, and even from single cells, are helping scientists to gain insights into the molecular pathways controlling lineage development. From these data it is already apparent that there are both similarities and significant differences between humans and mice in the developmental profiles of gene expression, including in some of the key genetic drivers known for mouse preimplantation development. It is possible to speculate about which of these genes are required to drive human preimplantation development, but it is not yet known how critical they are. These stem cell types are valuable for understanding molecular mechanisms of differentiation, as well as the properties of these cell lineages, which are relevant to placental and yolk sac biology in health and disease. However, attempts to derive equivalent extraembryonic stem cell types from human blastocysts have not yet been successful (Hayakawa et al. Such cell lines would be of great value, especially given the considerable evolutionary divergence seen in placental types among mammals. This divergence includes substantial differences in the types of cells comprising the human placenta compared to mice and other mammals. For example, syncytiotrophoblast cells that invade and directly interact with the endometrium (the cells lining the uterus/womb), are present in the placenta of great apes and may even have unique properties in humans. As a result, it is not possible to rely on knowledge gained from studying mouse cells to understand normal development of the human placenta. Similarly, it is not possible to understand pathologies in which the placenta or placental interaction with the mother fails, which can cause miscarriage, or when the placenta invades too vigorously into the uterus, which can lead to choriocarcinoma. All of the differences between humans and mice discussed above mean that it is not possible to accurately infer developmental events in human embryos from studying mice. Thus, there is considerable interest in experimental investigation of preimplantation human development in culture, in jurisdictions where such research on human embryos is permitted. The goals of this work are to understand the fundamental events of fertilization, activation of the embryonic genome, cell lineage development, epigenetic events such as X-inactivation, and others, and how these events compare and contrast with what is understood from studying mice. Similar research also could provide insights into the reasons for the high rates of early pregnancy loss in natural human pregnancies (10 to 45 percent, depending on the age of the mother), as well as the causes of infertility. Better understanding of sperm development would be crucial in addressing issues of male infertility. Better understanding of human embryonic development would provide insights into the origins and regulation of pluripotency and how to translate that knowledge into improved stem cells for regenerative medicine. Cell types that give rise to the yolk sac and the placenta also are determined in the early embryo prior to implantation. The yolk sac and placenta establish the crucial links with the mother during pregnancy and provide nutrients and other factors that enable the embryo to survive. Defects in these tissues can compromise a pregnancy, leading to miscarriage, premature birth, or postnatal abnormalities. Better understanding of how the yolk sac and placenta originate would help in improving techniques for overcoming infertility and preventing early miscarriage, as well as understanding and preventing congenital malformations. These extraembryonic cell types also provide cues that pattern the early postimplantation embryo, although almost nothing is known about these processes in humans. These possibilities and others discussed in this chapter are summarized in Table 3-1. None of these experiments would involve human pregnancies, so none could result in heritable germline modifications. They would all be in vitro experiments, with results being analyzed primarily at the blastocyst stage in the first 1-6 days of development. In some cases, there could be interest in exploring the effects of altering specific genes at the next stages of human development, notably the early stages after the embryo would implant in a uterus. Improved culture systems that allow human embryos to develop in culture during the implantation period are being developed. Such research also should lead to better ways of establishing and maintaining stem cells from these early embryonic stages, which could facilitate efforts to derive cell types for studies and treatments of disease and traumatic injury. Knowledge gained from these laboratory studies using genome-editing methods in early human embryos should also provide information about the suitability of these methods for any eventual potential clinical use. That is, basic research can be expected to inform an understanding of the feasibility of making heritable, and preferably nonmosaic, changes in the genome (see Chapter 5). Because human embryos that can be used in research are a valuable and relatively scarce resource, it will be important to ensure that the most efficient methods are used for these laboratory studies of their basic biology. Thus, it is likely that in the course of this research, various technical issues associated with improving the use of genome-editing methods in human embryos will be addressed. It is possible to alter these cells genetically and study the impact of the changes on the process of spermatogenesis itself or, in mice, the impact on the offspring. This is an active area of research because it may enable restoration of fertility in male cancer patients after radiation or chemotherapy. Through the use of genome-editing methods, this work also highlighted significant differences between mice and humans in the genes involved in specification of primordial germ cells. There is evidence as well that knowledge gained from studying later stages of spermatogenesis in mice may not always be applicable to the same process in humans. These findings reflect the role of research on human cells in answering questions about human biology. If human haploid gametes could be generated from human pluripotent cells, as they can be in mice, it would open up new avenues for understanding gametogenesis and the causes of infertility. It would also open up possibilities for using heritable genome modifications to address health problems that originate from genetic causes. Few new ethical issues are raised, although if the cells and tissues come from identifiable living individuals, donor consent and privacy will be a concern, and in most cases the protocols will be subject to at least some review by institutional review boards. As noted earlier, research using viable embryos is illegal in a small number of U. The review would include details of the proposal and the credentials of the researchers under the auspices of these independent, multidisciplinary committees of scientists, ethicists, and members of the public. The project proposal should include a discussion of alternative methods and provide a rationale for employing the requested human materials, including justification for the numbers of preimplantation embryos to be used, the proposed methodology, and for performing the experiments in a human rather than animal model system. This includes not only work with somatic cells, but also the donation and use of human gametes and embryos for research purposes, where this research is permitted. While there are those who disagree with the policies embodied in some of those rules, the rules continue to be in effect. This research is necessary for medical and scientific purposes that are not directed at heritable genome editing, though it will also provide valuable information and techniques that could be applied if heritable genome editing were to be attempted in the future. Existing regulatory infrastructure and processes for reviewing and evaluating basic laboratory genome-editing research with human cells and tissues should be used to evaluate future basic laboratory research on human genome editing. Somatic cells contribute to the various tissues of the body but not to the germline, meaning that, in contrast with heritable germline editing (discussed in Chapter 5), the effects of changes made to somatic cells are limited to the treated individual and would not be inherited by future generations. The idea of making genetic 40 changes to somatic cells, referred to as gene therapy, is not new, and considerable progress has been made over the past several decades toward clinical applications of gene therapy to treat disease (Cox et al. Hundreds of early-stage and a small number of latestage trials are underway (Mullin, 2016), although only two gene therapies have been approved as of late 2016 (Reeves, 2016). Existing technical approaches to gene therapy are based on the results of extensive laboratory research on individual cells and on nonhuman organisms, establishing the means to add, delete, or modify genes in living cells or organisms. Prospects for future applications of gene therapy have recently been greatly enhanced by improvements in genome-editing methods, particularly the development of nuclease-based editing tools (see Chapter 3). This chapter begins by providing background information on human somatic cell genome editing, including definitions of key terms. Next is a discussion of potential human applications of somatic cell genome editing. Scientific and technical considerations and ethical and regulatory issues are then examined in turn. Additional scientific and technical detail on methods for genome editing are provided in Appendix A. The haploid (single) human genome 40 Gene therapy denotes the replacement of faulty genes or the addition of new genes to cure or improve the ability to fight disease. Although people speak of the human genome, each genome differs from any other at many positions (around 1 in 1,000 base pairs, or about 3 million positions), and these genetic differences contribute to what makes individual humans unique (The 1000 Genomes Project Consortium, 2015). Many of these variations probably have little or no effect, but some affect the expression and/or functions of genes. Some variants in genes can change the properties of the proteins they encode, while other genomic variants can affect the expression of genes. Such variants influence the color of hair or eyes, blood type, height, weight, and many other individual features, although most human traits are affected by interactions among multiple genes. These alterations occur continually at a certain rate, and although cells have mechanisms for proofreading and correcting (editing) such changes, some escape the proofreading process and persist. As mentioned, many of these variants have little or no effect, but others have positive or deleterious effects. This process of variation in human genomes has been going on since before humans evolved as a separate species and continues to this day. Whether a particular variant is advantageous or deleterious, however, can vary with the context and may be a consideration in deciding whether to edit variants for clinical benefit. Genetically Inherited Diseases One primary impetus for interest in possible clinical applications of the recent advances in genome editing is the possibility that they provide new avenues for treating and preventing human disease. One such possible use is in the treatment of genetically inherited diseases, 41 thousands of which are known. Certain deleterious variants can be inherited from one or both parents, while others can arise de novo in the embryo rather than being inherited from either parent. If a variation that causes loss of function in a gene is inherited from one parent, it often has no evident effect, because the unaltered variant inherited from the other parent is sufficient to provide the function needed. Recessive gene variants usually (but not always) have little or no effect in the so-called heterozygous state, when two different variants are present in the fertilized egg (zygote) and in the subsequent child and adult. In that case, there is no functional variant is available, and the consequence may be a genetically inherited disease. Other variants may actually produce medical problems even when present in a single copy despite the presence of a functional gene variant. Such variants, called dominant, produce deleterious effects even in the heterozygous state. Some inherited diseases, such as certain forms of hemophilia, which affect blood clotting, involve genes that are present on the X chromosome (so-called X-linked). Because men have only one X chromosome, whereas women have two, a single abnormal X-linked hemophilia gene in a man will lead to the disease being manifest, whereas women with just one deleterious variant will be carriers of the altered gene, usually without having bleeding symptoms (so called silent carriers). Adding to the complexity of understanding genetic disorders is the observation, noted above, that some variants may be either deleterious or advantageous depending on the context. Probably the best known example is sickle-cell disease, which is caused by a variation in one of the genes encoding hemoglobin, the protein that carries oxygen in red blood cells. If the sickle hemoglobin variant is inherited from both parents (homozygous), it causes the hemoglobin protein to aggregate under certain conditions, leading to deformation of the red blood cells into a sickled shape that interferes with blood circulation, causing multiple difficulties and much pain and impairment of normal tissue functions. Heterozygous individuals (heterozygotes) who inherit just one sickle gene variant have few if any signs of disease and are known as carriers since they carry the sickle-cell variant and can pass it on to their children. It turns out that heterozygosity for this variant makes carriers somewhat resistant to malaria parasites that infect their red blood cells. That is, the sickle-cell variant provides a significant survival advantage in areas where malaria is present, and for that reason has been selected for and is relatively prevalent in such areas such as Africa, India, and the Mediterranean, where carriers are more common than in other areas. There are other examples of such balanced selection based on heterozygous advantage, balanced against the disadvantage of inheriting two disease-associated variants. Finally, it is important to note that most human diseases are thought to be affected by genetic variants in multiple genes, with each variant having only a minor effect on disease progression.

However, the volume of brain tissue is not only composed of densely infarcted tissue that will never recover, but also of tissue that has the potential to recover. In much the same way as a boat with a hole in its bottom will accumulate water, so too does the dying cell. The movement of water from the extracellular to the intracellular space results in a restriction of water diffusion as it is now confined within the cell, rather than in the larger extracellular space. Diffusion is the free movement of water molecules in a given volume by Brownian motion. Using our analogy of the ocean, if we were to put a piece of wood into the ocean, this piece of wood could drift anywhere, given the ocean is sdo large. On the other hand if you place the same piece of wood in a bath tab, it will remain in one place. As a result brain tissue undergoes ischemic necrosis (shaded blue region of the brain). Figure one is able to demonstrate how diffusion of water molecules reproduced by consent of Servier. This is followed in turn the tissue that approximately corresponds to the ischemic by cessation of electrical activity and finally by a loss of penumbra ure 40.

In trials of Cholinesterase inhibitors increase the concentration and central cholinesterase inhibitors, very small improvements duration of action of the neurotransmitter acetylcholine by or reduced rate of decline in memory, language, and/or visinhibiting the enzyme involved in its breakdown. Improvement in cortreatment of vascular dementia, donepezil was associated tical perfusion was also associated with an improvement with a small, but statistically significant, improvement in of neuropsychological functions. However, it is unclear cognition, overall function, and activities of daily living whether the improvement of neuropsychological functions (Salloway et al. At each increment in donepezil dose and at the end of the washout period, the Aphasia Quotient of the Western Aphasia Battery was 40. There was a mean increase in the Aphasia stantia nigra and ventral tegmental area and project to the Quotient associated with the use of donepezil and also supplemental motor area and prefrontal agranular regions. At the same time the mean Aphasia these pathways are part of the network involving the anteQuotient declined during the washout phase, suggesting rior cingulate gyrus, dorsolateral prefrontal and inferior that in this cohort, the use of donepezil was associated with frontal cortices. The mechanism of action nonfiuent aphasia and deficits in focusing attention and is thought to be due to the facilitation of neural plasticity concentration in language production. Piracetam projections from the midbrain to the cortex, it was hypothesized that bromocriptine could be used for the treatment of Piracetam belongs to the pyrrolidone family of chemitranscortical aphasia (Albert et al. The However, these results have not been confirmed in subsepyrrolidone group of compounds are unique in that subtle quent, larger, randomized placebo-controlled trials. The changes in their chemical structure can result in very difmost recent of these trials by Ashtary et al. An example that aphasia improved following intervention with either of this group is levetiracetam, which is related to piracetam bromocriptine and language therapy or language therapy but has a profound antiepileptic effect. However, there was no added benefit of bromocripcommon mechanism of action of potentiating acetylcholine tine over language therapy. In addition piracetam may potentiate neuron function with added neuroprotective functions such as enhancing cellular metabolism and oxidative glycolysis, as well as 40.

For a comprehensive dissertation dopamine, serotonin, and norepinephrine, while inhibiting on the pyrrolidone family of agents, the reader is directed reuptake from the synaptic cleft. In an initial unblinded pilot study, dexamphetamine was the Pharmacological Treatment of Aphasia 413 shown to have a positive effect on recovery of language in agreement that the intervention that most consistently results patients with aphasia due to subacute stroke (Walker-Batson in language improvement in aphasia is language therapy. A subsequent randomized, double-blind, placebo-controlled trial of dexamphetamine and language therapy versus language therapy alone enrolled 21 subacute 40. The initial, acute phase of stroke week period, the dexamphetamine treatment group showed results in a degree of neuronal dysfunction that depends more improvement in language function as tested by the on the degree of ischemia (reduction in blood fiow). This difference initial acute phase can be corrected by removal of the clot between the treatment and placebo arms was maintained and from the obstructed cerebral artery, via thrombolysis, stent even further improvement occurred at 6 months after dexaminsertion, or surgery. However, no effect has been yet docble or hazardous, then the improving collateral blood fiow umented in chronic aphasia (beyond 6 months), which may around the obstructed blood vessel, via volume expansion suggest that neural plasticity has a ceiling effect (McNeil or blood pressure elevating agents shows promise.

Ciprofoxacin is used with doxycycline and metronidazole to treat pelvic infammatory disease spasms rectal area mefenamic 500mg amex. Nalidixic acid is an older quinolone efectve in uncomplicated urinary-tract infectons and spasms during mri purchase mefenamic online from canada, in the treatment of shigella in areas where it remains susceptble muscle relaxant amazon buy mefenamic american express. Tetracyclines: Doxycycline is a tetracycline and is a broad-spectrum antbiotc efectve for conditons caused by chlamydia spasms caused by anxiety buy generic mefenamic 500mg, ricketsia spasms hiatal hernia buy 500mg mefenamic with mastercard, brucella and the spirochaete muscle relaxant comparison chart cheap mefenamic 250 mg otc, Borrelia burgdorferi (Lyme disease). It is the preferred tetracycline since it has a more favourable pharmacokinetc profle than tetracycline. It is deposited in growing bone and teeth causing staining and occasionally dental hypoplasia. It should not be given to children under 8 years or pregnant women; in some countries, use in children under 12 years is contraindicated. Aminoglycosides: Aminoglycosides including gentamicin are bactericidal and actve against some Gram-positve and many Gram-negatve organisms including Pseudomonas aeruginosa. Aminoglycosides are not absorbed from the gut and must therefore be given by injecton for systemic infectons. Use of gentamicin should be restricted to trained health personnel and care must be taken to ensure correct dosage and duraton of treatment are not exceeded, because most adverse efects are dose related. The most important adverse efects are ototoxicity and nephrotoxicity and they are most common in the elderly and in patents with renal impairment. These groups and, if possible, all patents should be monitored for ototoxicity by audiometry. If there is impairment of renal functon the dose interval must be increased; in severe renal impairment, the dose should also be reduced. If possible serum concentratons should be monitored in all patents, but must be measured in infants, the elderly, in obesity, in cystc fbrosis, in high-dosage regimens, in renal impairment, or if treatment lasts for longer than 7 days. For most infectons, doses of up to 5 mg/kg daily in divided doses are used if renal functon is normal; higher doses are used occasionally for serious infectons. It is associated with serious haematological adverse effects and should be reserved for the treatment of severe infections, particularly those caused by Haemophilus influenzae and typhoid fever. The oily suspension should be reserved for use in situations of catastrophic epidemics of meningococcal meningitis occurring mainly in sub-Saharan Africa, during which the medical services are overwhelmed by the epidemic and in which the overwhelming scale of the epidemic precludes any other form of antimicrobial therapy. Macrolides: Erythromycin is a macrolide; it has an antibacterial spectrum that is similar but not identical to penicillin and is used as an alternative in penicillin-allergic patients. Azithromycin is more actve than erythromycin against some Gram-negatve organisms such as Chlamydia trachomats. The concentraton and persistance of azithromycin is much higher in the tssue than in plasma; a single dose of azithromycin is used in the treatment of uncomplicated genital chlamydia and trachoma. Azithromycin is not recommended if there is a possibility of gonorrhoea because macrolide resistance emerges rapidly when it is used in this setng. Metronidazole: Metronidazole has high actvity against anaerobic bacteria and protozoa. Metronidazole by the rectal route is an efectve alternatve to the intravenous route when oral administraton is not possible. Sulfonamides and Trimethoprim: the usefulness of sulfonamides is limited by an increasing incidence of bacterial resistance. For many indicatons they have been replaced by antbiotcs that are more actve and safer. Sulfamethoxazole is used in combinaton with trimethoprim because of their synergistc actvity. In some countries, indicatons for the use of this combinaton have been restricted. The treatment of Pneumocysts carinii infectons must only be undertaken with specialist supervision where there are appropriate monitoring facilites. Trimethoprim is also used alone for respiratory-tract infectons and, in partcular, for urinary-tract infectons. Vancomycin: Vancomycin is not signifcantly absorbed from the gastrointestnal tract and must be given intravenously for systemic infectons which cannot be treated with other efectve, less toxic antmicrobials. It is used to treat serious infectons due to Gram-positve cocci including methicillin-resistant staphylococcal infectons, brain abscess, staphylococcal meningits and septcaemia.
