Definitions Definition: Antibiotics are molecules that kill, or stop the growth of, microorganisms, including both bacteria and fungi. Antibiotics that kill bacteria are called "bactericidal" Antibiotics that stop the growth of bacteria are called "bacteriostatic" B. Types of bacteria: Gram stain - A test, resulting in the classification of bacteria, developed in the last century by Hans Christian Gram, a Danish microbiologist - Gram positive bacteria will retain the original blue stain - Gram negative bacteria will lose the blue stain upon intermediate acetone treatment and will stain red 1 2 3 Definitions: Pneumonia: Inflammation of the lung, usually caused by bacteria or viruses. Otis media: Inflammation of the middle ear Endocarditis: Inflammation of the innermost tunic of the heart Septicemia: Systemic disease caused by the spread of microorganisms and their toxins via the circulating blood (also called "blood poisoning") Pathogen: a microorganism that causes disease.

Essential drugs should be available at all times blood pressure zone chart order labetalol 100 mg, in adequate amounts arteria spinalis anterior buy labetalol 100 mg overnight delivery, and in appropriate dosage forms arteria linguae profunda cheap labetalol 100 mg buy line. If only a limited number of drugs are used, health workers will be more familiar with indications, dosages, side effects and contraindications. A health facility with a clinical officer (medical assistant) or nurse in charge will use 30-40 essential drugs. But it is intended to provide a list of the drugs that are most essential to provide health care for the majority of the population in most developing countries. For example, cotrimoxazole (the official or generic name) is easier to recognise and remember than the range of alternatives, such as septrim, bactrim etc. Check appearance for colour changes and for unusual smells, in particular that: tablets are not chipped, broken, sticky or cracked; tubes of creams and ointments are not cracked; injections have no particles; clear vaccines are not cloudy; and bottles and vials are not cracked or chipped or seals broken. Make sure labelling (see Box, below) includes all the right information, including how the item should be stored. Appendix 2 Essential drugs 167 Labelling Clear, informative labels promote good practice. Access to certification is particularly important if you are procuring from sources other than national medical stores. Certification Manufacturing licence – shows a manufacturer is legally licensed to produce pharmaceutical products. In an emergency this requirement may be waived, but in normal circumstances not complying with it will cause problems. Where this is an issue, the manufacturer should be able to provide you with evidence that the product is registered for importation. See also Sections 1 and 2 of this book, as the same principles apply to procurement of essential drugs as to procurement of supplies and equipment. The usefulness of both methods depends on the accuracy of the information used to do the calculations. The choice of method will therefore depend on the availability of accurate stock receipts, issue records and morbidity data together with the existence and use of standard treatment guidelines. Table A1 Advantages and disadvantages of the consumption and morbidity methods of quantification Morbidity method Consumption method Advantages: Advantages: • Suitable for new or rapidly changing services. Disadvantages: • Easier to use in facilities dealing with a wide range of • Requires detailed and accurate morbidity data and health problems and more complex treatments. Using incomplete or inaccurate data Disadvantages: can result in over-estimates or under-estimates of • Requires reliable drug consumption data, accurate quantities required. If prescribing is poor this method may match use if standard treatments are not observed perpetuate it. For example, for a new facility you will need to use the morbidity method (if you know the population size in the catchment area, the incidence of disease, and standard treatments for these diseases) to calculate how much to order initially, but later you could use the consumption method. Or, for example, a facility using the consumption method may occasionally find it helpful to use the morbidity method to review prescribing standards. The consumption method may be more appropriate for facilities using a wide range of drugs, and the morbidity method for facilities using a more limited range of drugs according to standard treatment guidelines. Tables A2 and A3 show the steps in applying the consumption and morbidity methods. Appendix 2 Essential drugs 169 Table A2 Consumption method Step 1: Select the time period for calculating consumption For example: to calculate the quantity of cotrimoxazole 480mg tablets required for 12 months is the most practical time a 12 month period for 10,000 patients. You have the following data for 12 months: period to use for calculation, because it Opening stock balance 1000 tablets allows for seasonal variations in Items received 5000 tablets requirements. If the data you have Closing stock balance 2000 tablets available covers a shorter or longer time Wastage 0 period, use Step 4 to adjust it to Stockout 2 months calculate requirements for 12 months Step 2: Calculate the consumption for each item during the time period Recorded consumption = Opening stock balance + Stock received – Closing stock balance To calculate consumption you need accurate stock cards Recorded consumption = 1000 + 5000- 2000 = 4000 with a record of all items received and issued. Or you can calculate consumption for each item by adding together all the stock issues made (to do this you need a record of all items issued). You can estimate wastage by checking the Real consumption = 4000 – 0 = 4000 number of patients treated and items issued. Check to see how Period in stock (months, weeks, days) many are in the dispensary. Adjusted real consumption = 4000 x 12 = 4800 tablets You will also need to adjust the 4000 10 consumption figure for any item that has been out of stock for more than 1 month during the time period using the stock out formula.

Similarly, insect control may eliminate reservoirs for certain vector-borne diseases. Interrupting Disease Transmission Disease transmission can often be interrupted by the following: 2-9 rapid diagnosis and treatment of infectious diseases; isolation of patients from other crew members (when appropriate); chemoprophylaxis before exposure (i. Inactivating Infectious Agent Infectious agents can be inactivated to reduce the spread of disease. Proper disinfection and maintenance of potable water systems can prevent waterborne diseases caused by bacteria and viruses. Physical methods for inactivating infectious agents include use of heat (proper cooking of foods) and cold (refrigeration of foods). Proper food handling, preparation, and storage help to prevent outbreaks of food borne and diarrhea diseases. These simple yet essential practices should be carried out by staff and crew members of the ship. If crewmembers frequently develop diarrhea, the source of contamination should be aggressively sought and corrected. Further, they must use the recommended sanitation procedures for food purchase, storage and preparation. However, because so many people share the same environment, the same water, and the same meals on board a ship, a break in sanitation may allow diseases to spread quickly to many people or the entire crew. General principles include: 2-10 Maintain the potability (safety) of the water; Use reliable food suppliers; Keep the room temperature preparation times short; Keep raw and cooked foods entirely separate; also separate meat and fish, and fruit and vegetable prep areas; (including equipment, wiping cloths, storage areas, etc. Shellfish, especially scallops, accounted for four of the six seafood-related outbreaks on cruise ships. The more recent outbreaks showed that neither blanching nor marinating alone will make contaminated raw shellfish safe to eat. Steaming for at least 15 minutes may reduce the risk, if the entire product reaches a uniformly high temperature. It had been believed that the Salmonella was due to unclean eggs or eggs contaminated internally through cracks in the shells, and that the contents of an intact egg were sterile. Large outbreaks have been related to the use of bulk pooled eggs held for periods of time before cooking, or held on a steam table or buffet bar after partial cooking. Any recipe that calls for a large pool of eggs that are cracked ahead of time and held in a large container before cooking is of particular concern. Ground beef: While no food borne disease outbreaks aboard cruise ships have yet implicated ground beef as the source, this item could serve as a source of infection with Escherichia coli O157:H7 if not cooked properly. Infection often leads to bloody diarrhea and occasionally to kidney failure and death. Most illness has been associated with eating undercooked, contaminated ground beef. The Master should ensure the good sanitary conditions of the vessel through periodic inspections. Ensuring the health and safety of persons aboard a ship requires knowing and understanding the various factors on the ship that affect health. Preventing and controlling environmental health and safety problems will help to ensure the safety of the crew and the ship. This section will cover those factors, including food sanitation, potable water, pest management, laundry, barbershops, habitability, thermal stress, hazardous materials, respiratory protection, and confined spaces. By making the described practices an integral part of the ship’s routine, the Master and crew can contribute to the health, safety, and success of each journey. Most of the toxins of the past – such as the use of copper to color home canned green beans and lead solder to repair pots and pans – have been eliminated. Foodborne illness can be especially serious aboard ship, since nearly everyone eats from the same mess and contamination can infect an entire crew. Proper food procurement, storage, and preparation, along with personal hygiene, and sanitary food preparation areas go along way to ensuring the safety of the food served in the galley. All personnel who are assigned to work in the galley, even for a short period of time, must be trained in food sanitation and personal hygiene. It was developed primarily for shore-based facilities, but it also can assist the mariner in providing a system of safeguards to minimize foodborne illness aboard ship.

As with prior editions, the writing remains consistently concise, precise, and decisive. However, like the automotive industry of the City of Detroit, it has significantly transcended its local borders. All told, more than 30,000 copies have been distributed within the United States, Puerto Rico, Mexico, and Canada since its original publication. Overall, the content is current and crystallized, ready for translation into clinical practice. It should be on the "must have" list of Internal Medicine housestaff and Nephrology fellows-in- training as it continues to remain popular among the younger generation of physicians, nurses, and mid-level providers. Translation into other languages is under consideration and there is clamor for mobile device distribution. Standardization of the serum creatinine by isotope dilution mass spectrometry is occurring increasingly across clinical laboratories in the United States. Principally, proteinuria of 2+ on dipstick analysis or within the macro-albuminuric range portends a poorer renal outcome. Using kidney rather than renal improves understanding by patients, families, healthcare workers, and the lay public. Designations 5D and 5T indicate end-stage renal disease patients who undergo chronic dialysis (5D) treatment or have undergone kidney transplantation (5T). Recently, insulin resistance, obesity, and the metabolic syndrome have been implicated as risk factors. The increased utilization of pharmaceuticals has increased the frequency of immune-mediated (allergic) tubulointerstitial nephritis, particularly from antibiotics. Lastly, volume depleted patients are more susceptible to radiocontrast-induced nephropathy. Comprehensive systems targeting early recognition, prevention and management, and treatment by primary care physicians and physician extenders are required at this critical stage in collaboration with nephrologists. Their opinions also differed from nephrologists regarding evaluations by and expectations of nephrologists. Certain conditions such as malignancy, dementia, multiple comorbidities, or an advanced directive may preclude referral to a nephrologist. Electrolyte Abnormalities Na <130 mEq/L or >147 mEq/L in absence of diuretics K <3. In a prospective German study, the 5-yr survival rate was <10% in elderly type 2 diabetics and <40% in the younger type 1 cohort. The elderly, including patients 75 yr, are less likely to survive long enough to receive a deceased donor kidney transplant compared with non-diabetic patients. However, if left untreated, there is progression through phases of asymptomatic mesangial extracellular matrix accumulation, microalbuminuria, macro- albuminuria, and finally, overt proteinuric nephropathy. During the asymptomatic phase, glomerular hyperfiltration occurs with mesangial scarring. Due to the hyperglycemia-induced2 accumulation of matrix, diabetic kidneys are frequently normally sized when examined by ultrasound (normal: 10–12 cm). In some series, diabetic nephropathy may be accompanied by another non-hypertension-related kidney disorder in 5–15% of cases. The 24-h urine protein is considered the gold standard of urine protein determination as protein excretion may vary with the circadian rhythm, particularly in patients with glomerular disease.

These differences and their student status also alter the balance of responsibility from the individual to the approved body heart attack young labetalol 100 mg mastercard. Registered medical practitioners may work in an environment which challenges their professionalism and may face challenges in maintaining that professionalism blood pressure medication diabetes 100 mg labetalol visa. But the primary responsibility for maintaining their professionalism rests with them arrhythmia graphs purchase generic labetalol online. Medical students are adults, and also have a personal responsibility to maintain professionalism. However, in accordance with the Act, and its reference to “…guidelines for bodies…” there is a specifc requirement for an organisation–wide approach to fostering student professionalism and dealing with professional defcits. There is certainly an onus on approved postgraduate bodies to foster professionalism and on employers to facilitate it. But the one-to- one relationship of the individual practitioner with the Medical Council in cases of breaches of unprofessionalism marks a signifcant difference. The Medical Council’s relationship with individual students in this regard is an indirect and vicarious one, mediated via the medical school; and the medical school plays the pivotal part in fostering professionalism and tackling professional defcits. The medical schools’ central role in fostering professionalism and tackling professional defcits will continue. Medical schools should offer appropriate opportunities for their own staff to contribute to developing this evidence base, and should aim to incorporate relevant research fndings into their curriculum development and delivery processes. These Guidelines are informed by the evidence base but their focus is a practical one. In providing Guidelines for medical students and medical schools on professionalism and dealing with professional defcits, it aims to provide a framework for action. For programmes and bodies, the decision may be approval; or approval with conditions; or the amendment or removal of previous conditions attached; or withdrawal of approval. The Council has previously monitored medical schools’ implementation of the Guidelines for Medical Schools on Ethical Standards and Behaviour Appropriate for Medical Students, and students’ awareness of them. It will continue this process with these new Guidelines, factoring medical schools’ implementation into Medical Council processes for accreditation, including into the Annual Return. These Guidelines are not intended to deal with defcits due to a health problem (whether short-term or chronic) or a particular psychological trauma (such as bereavement). Medical students, like all students have the right to access services that support their well-being and provide for the prevention of illness and treatment of medical and psychological conditions. However, medical schools must be aware of the particular relevance of effective management of medical students with relevant medical and psychological conditions. Medical schools must take action if there is evidence that a student’s medical or psychological condition is adversely affecting a student’s conduct and behaviour and, in particular, is affecting or may affect patient well-being and safety. The perspectives of individuals and groups shape and frame the understanding of medical professionalism. The exchange and interplay of these different perspectives - discourse - involves concepts of: Individual professionalism; professionalism as an individual personal attribute, or set of attributes Interpersonal professionalism; professionalism as a feature that emerges through social interaction Collective professionalism; professionalism as an attribute or set of attributes relating to the “contract” between the medical profession and society Complex professionalism; professionalism as a dynamic construct which shifts over time. The purpose of these Guidelines is basically a practical one: providing guidelines on developing and reinforcing professionalism, and dealing with professional defcits, which are useful to medical schools and students. The working defnition of professionalism that underpins these Guidelines is therefore as follows: Medical professionalism is the set of intrinsic values, expressed as extrinsic behaviours which justify the trust between patients and good doctors, and between the public and the medical profession. These values and behaviours include: Respect for patients demonstrated by patient–centred practice Ethical standards including honesty, integrity, empathy and altruism demonstrated by ethical practice Refection/self-awareness demonstrated by refective practice Personal responsibility for actions demonstrated by responsible behaviour, including safeguarding one’s own health and well-being Theamwork commitment demonstrated by effective communication and teamwork, including, where appropriate, acting as the leader of a team Social responsibility demonstrated by commitment to the health of the community. The attributes of professionalism are in most cases applicable to all stages of a doctor’s career, from the frst day in medical school until the day they retire from active practice. The issue of online professionalism, for example, is included in these Guidelines. The range of ways in which professionalism can be demonstrated will evolve; working as a very junior member of the clinical team is very different to being the leader of the team, but both require team-working skills. Students will inevitably be at a formative stage of understanding and demonstrating professionalism. Professionalism will evolve and it will adapt as global, national, local and individual circumstance adapt. Indeed, appropriate adaptation to changing circumstances is part of being a professional, as is a commitment to lifelong learning and personal and professional development.

Humans can be infested by 12 species of Argasidae (Argas and Ornithodoros) and 22 species of Ixodidae (4 of the genus Amblyomma heart attack water generic 100 mg labetalol with mastercard,7of Dermacentor blood pressure medication for diabetics buy 100 mg labetalol otc,3of Haemaphysalis arrhythmia update buy 100 mg labetalol with amex,2of Hyalomma, and 6 of Ixodes) (Estrada-Pena and Jongejan, 1999). The most common were Amblyomma ameri- canum in the south and near the Atlantic Ocean; Dermacentor variabilis and Ixodes scapularis in the east; Dermacentor andersoni in the west; Ixodes pacificus near the Pacific; and Ornithodoros spp. North Carolina reported human infestations with Otobius megnini, Amblyomma maculatum, Haemaphysalis leporispalustris, Ixodes cookei, Ixodes dentatus, and R. In one locality in Italy, during 1995 and 1996, 240 infested individuals were found, with an average of 1. Eleven percent of the cases occurred in children, 26% in students, 22% in workers, and 24% in retired persons. During the period studied, the preva- lence of bites was 5 per 1,000 residents (Manfredi et al. The Disease in Man: Ticks cause damage directly by biting and by sucking blood, since they cause allergic reactions by injecting toxins and transmit infections. It has also been found that ticks cause a depressed immune response (Barriga, 1999), but the importance of that is probably minimal. It may be that the direct damage ticks cause is slight in human beings because the majority of infestations are due to a single arthropod and the patient does not notice it. The case of Amblyomma testu- dinarium of Japan is noteworthy, since it caused infestations with more than 100 lar- vae (Nakamura-Uchiyama et al. The mouthparts that remain in the wound when the tick is removed can cause a granuloma that looks like a pustule and lasts for several weeks. Ticks are generally not included among the arthropods that cause allergies; how- ever, there are reports of severe allergic reactions. For example, symptoms have been reported ranging from erythematous reactions to ulcerative lesions caused by Argas reflexus (pigeon tick) (Veraldi et al. A paralysis caused by the female of certain ticks feeding on their hosts has been described in both animals and humans; approximately 20 species have been iden- tified: D. While it is suspected that the paralysis is due to a toxin, it has been identified only in the case of the Australian tick I. The patients experienced an ascending symmetrical flaccid paralysis that causes respiratory paralysis after about a week; the illness ends when the arthro- pod is removed, but recovery is slow. Transmission of infection is the most serious concern in connection with tick infestation of humans. Since the number of ticks that attack a single ani- mal can be very high, inflammation, pain, and pruritis are intense, due either to the trauma or hypersensitivity, and distract the cattle from feeding, in addition to caus- ing weight loss. Also, the wounds caused by the ticks can ruin the skins for indus- trial use and attract fly attacks that result in myiasis. The sucking of blood can be significant when the infestation is intense and can also promote weight loss, since the cattle have to expend energy to replace the blood loss. With respect to the transmission of disease, ticks play a role as important for animals as mosquitoes play for humans. Some of the most severe cattle diseases are tick-borne, such as babesiosis (see chapter on Babesiosis), theileriosis, cowdriosis (hydropericardium), and anaplasmosis (Uilenberg, 1997). Source of Infestation: The source of infestation is the environment contaminated with ticks; in the case of hard ticks, the vegetation where the hungry larvae are found in large numbers; in the case of soft ticks, the dwellings with cracks where they can find shelter during the day. While infested animals are the source of contamination of the environment, they are rarely a direct source of infection for man or other ani- mals. Studying them should not be difficult because even the tick larvae measure more than 1 mm, and they are red or dark after feeding. However, the tick is often located on parts of the body where the infested person cannot see it, including behind the ears, where even the doctor can miss it if he or she is not specifically looking for it. When removing a tick, it is important to extract the mouthparts from the skin to prevent the forma- tion of granulomas; to ensure this, the body must be pulled continuously for one minute, without excessive force, in a direction perpendicular to the patient’s skin, until the grip is loosened. It is advisable to remove the tick with tweezers or a plas- tic sheet to avoid contact with its blood if it should explode, since the fluid may con- tain pathogenic organisms.

The same mode of direct disease transmission can also apply to aircraft imported vectors of dengue prehypertension remedies generic 100 mg labetalol with mastercard, yellow fever heart attack during sex generic labetalol 100 mg line, Chikungunya hypertension in pregnancy 100 mg labetalol order with amex, Japanese-B-encephalitis, West-Nile virus, leishmaniasis, filariasis and others. Even the importation of uninfected insect species which are susceptible to certain diseases can contribute to the emergence of new diseases. Establishment of imported insect vectors is most likely if the climatic and environmental conditions at the destination are similar to those at the place of origin. Cockroaches, ants and other insect pests can enter the aircraft through cargo goods, baggage or catering equipment. They are not usually regarded as direct disease transmitters but can be harmful as they may contaminate food or cause damage to the aircraft infrastructure particularly the electronic equipment. Some of these insects may find suitable conditions and breeding sites on board if regular treatment and preventive measures are not undertaken. Some countries allow health authorities to order disinsection of arriving aircraft if proof of properly performed disinsection is not demonstrated. Insects and other pests entering aircraft usually emerge from the area around the aircraft, from the airport and equipment brought into the aircraft. Aircraft disinsection in its broad sense therefore includes preventive pest control measures in and around airports. Aircraft disinsection methods have to take into consideration: that insecticides have to be applied in very close contact to passengers and crew; that the interior of aircraft contains a number of sensitive materials such as electronic equipment, with the attendant fire risk; that the active ingredients used for disinsection must be effective against a broad spectrum of insects. Reports on the growing development of resistance among insect vectors in many regions indicate the need for continued development and evaluation of alternative insecticides. Efficacy of disinsection methods does not depend only on the active ingredients used but also on the mode of application and the technical properties of the dispenser used for aerosol spraying. The empty spray cans are to be retained for inspection by the Port Health Authority on arrival. Although not regarded as a preferred method, the on-arrival-method may be retained as an acceptable back-up method if an aircraft, coming from areas of threat, has not been adequately disinsected by any of the recommended methods. On arrival, before doors are opened and disembarkation is permitted, agents of the Health Authority board the aircraft and perform disinsection of the cabin and flight deck similar to the “blocks-away” method. Pre-flight spraying The pre-flight spray containing 2% permethrin must be applied to the flight deck, all toilet areas, lockers, wardrobes and crew rest areas, except where approval has been granted for the residual treatment (see below) of these areas. Pre-flight spraying of the residual insecticide shall equate to a rate of 35 g of the formulation per 100 m3 (10 g per 1000 ft3). Top-of-descent (in-flight spraying) The second step of this method is carried out at “top-of-descent” as the aircraft starts its descent to the airport of arrival. A quick-acting “knock-down” insecticide is sprayed into the passenger cabin by crew members walking along each aisle holding 2 ´ 100 g cans at a slow walking pace of one row per second starting at the rear of the aircraft. An announcement shall be made before in-flight spraying is started and passengers who feel that it may cause them inconvenience should be advised to close their eyes and cover their faces while the procedure is carried out. The spraying is to be applied as near as possible to the ceiling at a rate of 35 g of the formulation per 100 m3 (10 g per 1000 ft3). An entry confirming the treatment should be made in the aircraft “declaration of health” and the empty spray cans of pre-flight and in-flight spraying must be retained in the aircraft and delivered to the appropriate authority on arrival. The procedure aims at producing an even film of the residual insecticide permethrin on all interior surfaces of the aircraft to ensure that if an insect gains access to the aircraft and lands on a surface it will receive an effective dose of insecticide. After spraying is completed, air conditioning packs should be run for at least one hour to clear the air of the volatile components of the spray. Treatment must be at intervals not greater than two months to ensure efficacy of the insecticidal film. Replacement carpets or seat covers which are exchanged within the 2 month period shall be retreated. A “Certificate of Residual Disinsection” shall be issued by the appropriate authority and signed by the person who supervised the treatment. It does not require passengers and crew to be exposed to aerosol sprays and has the added benefit of lessening the workload of aircraft cabin crew. Many airlines operating flights scheduled to destinations where disinsection is needed are using the residual treatment as the current method of first choice. Even without adverse health effects, many airline customers find the spraying of aerosols in the cabin a nuisance. This disinsection procedure consists of spraying all interior spaces of the aircraft with an aerosol containing 2% permethrin insecticide before embarkation. Trials have proven the efficacy of this method killing all flying insects and others which gained access to the aircraft.
