A core set of screening erectile dysfunction nutritional treatment purchase 100 mg sildenafil amex, clinical impotence vasectomy order sildenafil 25mg overnight delivery, and functional status elements diabetic erectile dysfunction icd 9 code sildenafil 100 mg fast delivery, including common definitions and coding categories, which forms the foundation of a comprehensive assessment for all residents of nursing homes certified to participate in Medicare or Medicaid. Once a care area has been triggered, nursing home providers use current, evidence-based clinical resources to conduct an assessment of the potential problem and determine whether or not to care plan for it. The triggers identify residents who have or are at risk for developing specific functional problems and require further assessment. These resources include a compilation of checklists and Web links that may be helpful in performing the assessment of a triggered care area. The use of these resources is not mandatory and the list of Web links is neither all-inclusive nor government endorsed. Please refer to the Medicare Internet-Only Manuals, including the Medicare Benefit Policy Manual, located at. Consumers are also able to access information about every Medicare- and/or Medicaid-certified nursing home in the country. Such a team brings their combined experience and knowledge to the table in providing an understanding of the strengths, needs and preferences of a resident to ensure the best possible quality of care and quality of life. In addition, an accurate assessment requires collecting information from multiple sources, some of which are mandated by regulations. As such, nursing homes are responsible for ensuring that all participants in the assessment process have the requisite knowledge to complete an accurate assessment. All good problem identification models have similar steps to those of the nursing process. Assessment-Taking stock of all observations, information, and knowledge about a resident from all available sources. Identification of Outcomes-Determining the expected outcomes forms the basis for evaluating resident-specific goals and interventions that are designed to help residents achieve those goals. This also assists the interdisciplinary team in determining who needs to be involved to support the expected resident outcomes. Evaluation-Critically reviewing individualized care plan goals, interventions and implementation in terms of achieved resident outcomes as identified and assessing the need to modify the care plan. This occurs not only because it follows an interdisciplinary problem-solving model, but also because staff (across all shifts), residents and families (and/or guardian or other legally authorized representative) and physicians (or other authorized healthcare professionals as allowable under state law) are all involved in its "hands on" approach. The result is a process that flows smoothly and allows for good communication and tracking of resident care. Nursing home staff report that, as individualized attention increases, resident satisfaction with quality of life also increases. Knowledge gained from careful examination of possible causes and solutions of resident problems. There has been a dramatic increase in the frequency and nature of resident and family involvement in the care planning process. Input has been provided on individual resident goals, needs, interests, strengths, problems, preferences, and lifestyle choices. When considering all of this information, staff members have a much better picture of the resident, and residents and families have a better understanding of the goals and processes of care. When the approaches to achieving a specific goal are understood and distinct, the need for voluminous documentation diminishes. Likewise, when staff members are communicating effectively among themselves with respect to resident care, repetitive documentation is not necessary and contradictory notes do not occur. Basically, when everyone is speaking the same language, the opportunity for misunderstanding or error is diminished considerably. Such gains should improve identification of resident needs and enhance resident-focused care planning. In addition, inclusion of items recognized in other care settings is likely to enhance communication among providers. These significant gains reflect the cumulative effect of changes across the tool, including: use of more valid items, direct inclusion of resident reports, and improved clarity of retained items. Identify behavioral symptoms that may cause distress or are potentially harmful to the resident, or may be distressing or disruptive to facility residents, staff members or the environment. Document the risk, presence, appearance, and change of pressure ulcers as well as other skin ulcers, wounds or lesions. Record the number of days that any type of injection, insulin, and/or select medications was received by the resident.

There is also the concept of the "good girl," which needs to be tackled in the schools. Finally, there is what I call "from the peak to the plains", a reminder to all those women who have climbed to the top not to forget the women behind them, where they come from. As Dr Rosa Elena Simeуn, an extraordinary Cuban scientist, once said, "when a woman plays a leadership role, she promotes other women in the process," as an encouraging role model and inspiration. Lilliam Бlvarez: We need to build a future for the planet and for our country that is sustainable, in harmony with nature, that develops high standards of health and education, prevents vulnerabilities and above all does this by using the beneїts of science. Through education and science, both governmental and nongovernmental actors can make better and more rational, informed decisions. All of this requires a gender perspective, which has to be present in all spaces of society. We need to move to greater equity in our socialist context, further opening the doors for the new generation of women.

Several provinces reported over 120 cases per 100,000 children aged <1 year, overwhelmingly serogroup B. Its efїcacy of 83% was demonstrated in a prospective, randomized, double-blind, placebo-controlled їeld study. Mass, systematic vaccination shifted the spectrum of meningococcal strains in healthy asymptomatic carriers and strains circulating among population groups toward nonvirulent phenotypes. The vaccine and its proteoliposome technology have had an impact and continue to have potential, not only for meningococcal disease, but also for development of other vaccines and adjuvants. Its main variants are meningitis and septicemia, both severe conditions and leading causes of invasive bacterial infection. During epidemics in the "meningitis belt" (SubSaharan African countries from the Gambia to Sudan), up to 1% of the population might become ill. Meningococcal disease caused by serogroup B meningococci occurs mainly in the countries of North America, central and southern Europe, southern and northeastern Africa, the Middle East, Russia, China, Japan, Australia and New Zealand. After mass vaccination was instituted, beginning in 1989, meningococcal disease ceased to be a public health problem and Cuba no longer appears among the hot spots still found in other regions. The paper also describes its impact on population health in Cuba and other countries, especially in children and young people, as well as the contributions of its production technology to scientiїc and technological advances in the biotechnology industry. Incidence due to serogroup C decreased, but meningococcal disease continued to increase, and in 1980 reached 5. The highest development achieved by the most advanced groups was a serotype-specific antigen vaccine; its characteristics are summarized in Box 1 and compared with the Cuban vaccine. Developing this vaccine candidate involved creating a scalable and integrated production system with complex know-how for initial culture, fermentation, extraction, puriїcation, formulation, adjuvantation, bottling and packaging. Studies of the vaccine before licensing and mass administration From 1987 to 1989, a prospective, randomized, double-blind, placebo-controlled efїcacy study was carried out in 7 provinces, involving 106,251 youngsters aged 1016 years. Experimental formulations included capsular polysaccharides from other groups for better solubility. Lipopolysaccharide was mainly free or formed part of blebs or membrane fragments and had to be eliminated to the extent possible, due to its toxicity. These were laboratory-scale efforts, lacking established technologies and good manufacturing practices. There was no demonstrated correlate of protection in controlled efїcacy tests in humans. The їeld study lasted 16 months, during which 25 cases of meningococcal disease occurred. Once concluded, the blinding code was broken, revealing whether cases were in the placebo or vaccinated group: there were 4 cases among the 52,966 who received the vaccine, and 21 among the 53,285 who received the placebo. High-risk groups were also included,  After 2008, four serotype B:17 strains, never before reported mainly workers and students living in dormitories, prisoners, in Cuba, appeared.

Although pharmacotherapies such as paregoric and phenobarbital have been shown to erectile dysfunction middle age generic sildenafil 25mg on line be effective for treating infants suffering symptoms associated with in utero drug exposure (Kandall, this volume), the 12 development of safer and more effective medications and better dosage forms, such as transdermal drug delivery systems, are of great interest. With recent advances in neuroscience, imaging techniques, and pharmaceutical technology, the development of medications for significantly improving drug abuse treatment in a variety of directions holds real promise. Pharmacological study of pentazocine-naloxone combination: Interest as a potentially non abusable oral form of pentazocine.

Narcotic Antagonists: Naltrexone Pharmacochemistry and Sustained-Release Preparations. General Accounting Office (1990) report to Congress suggested that each year between 100,000 and 375,000 women use illicit drugs including marijuana during pregnancy. There is currently no national prevalence data regarding prenatal cocaine or other illicit psychoactive substance use. Children with a history of prenatal cocaine exposure, labeled "crack kids," were portrayed in the media as inevitably and permanently damaged. An article in the New York Times reported that "parents and researchers say a vast majority of children exposed to significant amounts of drugs in the womb appear to have suffered brain damage which cuts into their ability to make friends, know right from wrong, control their impulses, gain insight, concentrate on tasks, and feel and return love" (Blockner 1990, p. Another article stated that these babies are "like no others, brain damaged in ways yet unknown, oblivious to any affection" (Hopkins 1990, p. These statements are made in spite of the absence of any credible scientific 16 evidence regarding the sequelae of prenatal cocaine exposure beyond the newborn period. Moreover, a social sentiment has arisen that the loss of these children is entirely attributable to the prenatal effects of cocaine (an irreversible biological factor). The labels used to describe drug-exposed children are themselves damaging, since labels have a way of becoming self-fulfilling prophecies (Rosenthal and Rosenow 1979). Even more damaging is the difficulty in finding adequate nonbiological homes for such children; potential foster or adoptive parents are often reluctant to assume the care of cocaineexposed children because of their perceived impairments. Labels also carry with them a risk for biasing and undermining scientific and clinical decisions. A 1989 report in Luncet indicated that abstracts regarding the impact of prenatal cocaine use were more likely to be accepted for presentation at the annual meeting of the Society for Pediatric Research if they reported positive results. Another study showed that, given an equivalent extent of use of illegal drugs by pregnant women, physicians and clinics are more likely to report African-American women or women on welfare to law enforcement agencies than white or middle-class women (Chasnoff et al. Prejudice exists, and it can well bias data interpretation, particularly when observers are not blind to study group assignment. Condemning these drug-exposed children with labels indicating a permanent handicap is premature. Such prophecies of doom lead researchers to overlook what has long been known about the remediating 17 effects of early intervention. Studies of preterm or ill newborns fail to support biological determinism (Beckwith and Parmalee 1986; Hunt et al. Supportive environments contribute significantly to improving the outcome of infants with biological vulnerabilities at birth (Beckwith and Parmalee 1986; Infant Health and Development Program 1990). Even among infants exposed to narcotics prenatally, the home environment is a critical determinant of outcome (Johnson et al. Future research is needed to determine if children prenatally exposed to psychoactive drugs suffer behavioral and developmental problems. If problems are identified, the areas of impaired development need to be determined, and the relative effects of prenatal psychoactive substance exposure and postnatal home environment must be assessed. Methodologic Issues the authors have recently summarized a number of important methodologic issues that contribute to uncertainty in findings that describe the effects of prenatal psychoactive substance exposure (Frank et al.

Intra-cardiac epinephrine is not recommended, even as a final measure when all else has failed. Give atropine before epinephrine if: You see a severe bradycardia You suspect excessive vagal tone as a cause (unusual) of asystole. Vasoconstrictors are sometimes used in septic shock, but usually with limited effect. Calcium chloride 10 mg in 10 ml during a cardiac arrest may be used to promote the effects of adrenaline and improve myocardial contractility. They can be used in conjunction with vasodilators such as hydralazine, nitrates and calcium blockers. This type of complex therapy is more likely to be used by a physician in a tertiary hospital. The events leading up to admission should be carefully considered: for example, following an accident: 1320 Resuscitation and preparation for anaesthesia and surgery When did it happen? The history is also important with non-trauma emergency surgery but, when there are delays in reaching hospital, perhaps of a week or even a month, the events that started the illness may have been forgotten. In the case of a child with a breathing difficulty, listen carefully to the history from the parent or guardian. If a child has a sudden onset of airway obstruction you may learn, on questioning the parents, that the problem has been there intermittently for a longer period, making laryngeal polyps more likely. In the case of an unconscious patient where there is no cause apparent, the history will usually give the diagnosis. In the case of a patient needing surgery and anaesthesia, the pathological problem requiring surgery and the proposed operation are also of obvious importance. Ask the patient about previous operations and anaesthetics and about any serious medical illnesses in the past. After listening to the history, you should have some idea of a provisional diagnosis. Before starting the clinical examination, make an "end-of-the-bed" examination of such signs as: Breathing pattern (flail segment, asymmetrical or paradoxical movement, tachypnoea, dyspnoea) Position of patient (sitting up or lying down) Position of arms and legs (showing limb or pelvic fracture) Restlessness, such as from pain, hypoxia or shock Dehydration (skin turgor, sunken eyes) Distended abdomen Scars of recent surgery or dressings covering a wound that has not been inspected Blood stained clothes. A thready pulse means difficulty in taking blood pressure and a poor circulation In hypertensive states, such as pre-eclampsia, the blood pressure is sometimes high but hard to detect In shock, the blood pressure is low with a fast pulse. An emergency surgical case with concurrent cardiorespiratory disease will need careful postoperative management, oxygen and close monitoring. At the very least, this information will tell you about how long surgery will take and whether haemorrhage is likely. Ultrasound scan is an important investigation in the management of the nontympanic distended abdomen. Soft abdomen Palpation of a soft abdomen is more informative Pain on palpation of a mass and fever suggest inflammation A fixed mass, without fever, suggests the possibility of a tumour. Once you have decided on your anaesthetic technique, explain briefly to the patient what will happen, with reassurance that you will be present all the time to look after breathing and the function of the heart and to make sure that he or she feels no pain. Also explain what to expect on awakening, such as: Oxygen Intravenous infusion Nasogastric tube or surgical drains. Once this has been done, it is advisable to ask the patient (or the parents in the case of a child) to confirm by signing that they agree with what you are planning to do. If you are referring a patient, a clear, legible referral letter is of great importance. Give dates and times, symptoms on admission and describe what treatments have been given so far. Such "screening" investigations are expensive and may not be affordable or available in your hospital. Only ask for an investigation if: You know why you want it and can interpret the result You have a management plan that depends on the result. We are fortunate in the management of emergencies: most of what we need to know for the safe conduct of anaesthesia can be learned at the bedside from physical signs.

The difference between intake and output of nitrogenous compounds is known as nitrogen balance fast facts erectile dysfunction order 75 mg sildenafil fast delivery. In a healthy adult erectile dysfunction vitamin deficiency order sildenafil 50mg online, nitrogen balance is in equilibrium erectile dysfunction ed drugs cheap 75mg sildenafil with mastercard, when intake equals output, and there is no change in the total body content of protein. In a growing child, a pregnant woman, or a person in recovery from protein loss, the excretion of nitrogenous compounds is less than the dietary intake and there is net retention of nitrogen in the body as protein-positive nitrogen balance. In response to trauma or infection, or if the intake of protein is inadequate to meet requirements, there is net loss of protein nitrogen from the body-negative nitrogen balance. Except when replacing protein losses, nitrogen equilibrium can be maintained at any level of protein intake above requirements. A high intake of protein does not lead to positive nitrogen balance; although it increases the rate of protein synthesis, it also increases the rate of protein catabolism, so that nitrogen equilibrium is maintained, albeit with a higher rate of protein turnover. The continual catabolism of tissue proteins creates the requirement for dietary protein, even in an adult who is not growing; although some of the amino acids released can be reutilized, much is used for gluconeogenesis in the fasting state. Average intakes of protein in developed countries are of the order of 80100 g/day, ie, 1415% of energy intake. Because growing children are increasing the protein in the body, they have a proportionally greater requirement than adults and should be in positive nitrogen balance. Even so, the need is relatively small compared with the requirement for protein turnover. In some countries, protein intake is inadequate to meet these requirements, resulting in stunting of growth. Prolonged bed rest results in considerable loss of protein because of atrophy of muscles. Protein catabolism may be increased in response to cytokines, and without the stimulus of exercise it is not completely replaced. Lost protein is replaced during convalescence, when there is positive nitrogen balance. The Requirement Is Not Just for Protein, but for Specific Amino Acids Not all proteins are nutritionally equivalent. More of some is needed to maintain nitrogen balance than others because different proteins contain different amounts of the various amino acids. There are nine essential or indispensable amino acids, which cannot be synthesized in the body: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. If one of these is lacking or inadequate, then regardless of the total intake of protein, it will not be possible to maintain nitrogen balance, since there will not be enough of that amino acid for protein synthesis. Two amino acids, cysteine and tyrosine, can be synthesized in the body, but only from essential amino acid precursors-cysteine from methionine and tyrosine from phenylalanine. The dietary intakes of cysteine and tyrosine thus affect the requirements for methionine and phenylalanine. The remaining 11 amino acids in proteins are considered to be nonessential or dispensable, since they can be synthesized as long as there is enough total protein in the diet. If one of these amino acids is omitted from the diet, nitrogen balance can still be maintained. However, only three amino acids, alanine, aspartate, and glutamate, can be considered to be truly dispensable; they are synthesized from common metabolic intermediates (pyruvate, oxaloacetate, and ketoglutarate, respectively). The remaining amino acids are considered as nonessential, but under some circumstances the requirement may outstrip the capacity for synthesis. Polysaccharides are absorbed as monosaccharides, triacylglycerols as 2-monoacylglycerols, fatty acids and glycerol, and proteins as amino acids. In addition to water, the diet must provide metabolic fuels (carbohydrate and fat) for body growth and activity, protein for synthesis of tissue proteins, fiber for roughage, minerals for specific metabolic functions, certain polyunsaturated fatty acids of the n-3 and n-6 families, and vitamins, organic compounds needed in small amounts for other essential functions. Twenty different amino acids are required for protein synthesis, of which nine are essential in the human diet. The quantity of protein required is affected by protein quality, energy intake, and physical activity.

Proceedings of a workshop to develop methodologies for conducting research on the effects of seismic exploration on the Canadian east coast fishery, Halifax, Nova Scotia, 7-8 September 2000. Measuring hearing in the harbor seal (Phoca vitulina): Comparison of behavioral and auditory brainstem response techniques. The potential effect of seismic sounds on fish has been studied with a variety of taxa, including marine, freshwater, and anadromous species (reviewed by Fay and Popper 2000; Ladich and Popper 2004; Hastings and Popper 2005; Popper and Hastings 2009a,b). It is sometimes difficult to interpret studies on the effects of underwater sound on marine animals because authors often do not provide enough information, including received sound levels, source sound levels, and specific characteristics of the sound. Specific characteristics of the sound include units and references, whether the sound is continuous or impulsive, and its frequency range. Underwater sound pressure levels are typically reported as a number of decibels referenced to a reference level, usually 1 micro-Pascal (µPa). However, the sound pressure dB number can represent multiple types of measurements, including zero to peak, peak to peak, or averaged (rms). Unless precise measurement types are reported, it can be impossible to directly compare results from two or more independent studies. Acoustic Capabilities Sensory systems like those that allow for hearing provide information about an animal`s physical, biological, and social environments, in both air and water. Extensive work has been done to understand the structures, mechanisms, and functions of animal sensory systems in aquatic environments (Atema et al. All fish species have hearing and skin-based mechanosensory systems (inner ear and lateral line systems, respectively) that provide information about their surroundings (Fay and Popper 2000). Fay (2009) and some others refer to the ambient sounds to which fishes are exposed as underwater soundscapes`. Anthropogenic sounds can have important negative consequences for fish survival and reproduction if they disrupt an individual`s ability to sense its soundscape, which often tells of predation risk, prey items, or mating opportunities. Potential negative effects include masking of key environmental sounds or social signals, displacement of fish from their habitat, or interference with sensory orientation and navigation. As with other vertebrates, fish hearing involves a mechanism whereby the beds of hair cells (Howard et al. At least two major pathways for sound transmittance between sound source and the inner ear have been identified for fishes. The most primitive pathway involves direct transmission to the inner ear`s otolith, a calcium carbonate mass enveloped by sensory hairs. The inertial difference between the dense otolith and the less-dense inner ear causes the otolith to stimulate the surrounding sensory hair cells. The second transmission pathway between sound source and the inner ear of fishes is via the swim bladder, a gas-filled structure that is much less dense than the rest of the fish`s body. The swim bladder, being more compressible and expandable than either water or fish tissue, will differentially contract and 14 By John R. The pulsating swim bladder transmits this mechanical disturbance directly to the inner ear (discussed below). Such a secondary source of sound detection may be more or less effective at stimulating the inner ear depending on the amplitude and frequency of the pulsation, and the distance and mechanical coupling between the swim bladder and the inner ear (Popper and Fay 1993).

Primary Endorser: In Vitro and Alternative Methods Specialty Section Other Endorser(s): Risk Assessment Specialty Section; Women in Toxicology Special Interest Group Evaluating the safety and potential health risks from exposure to multiple chemicals, such as environmental chemicals, pharmaceuticals, consumer and personal care products, and pesticides and food contaminants, poses one of the major challenges for toxicological research and risk assessment. Significant advances have been made in recent years in better understanding and evaluating chemical mixtures. A key factor in risk assessments of chemical mixtures is the availability of reliable data on the identity, levels of exposure, toxicokinetics, toxicodynamics, and toxicological interactions for the whole mixture or its individual components. Limited data or lack of data has a direct impact on uncertainty of the risk assessment of mixtures. As a result, risk assessment of chemical mixtures requires a lot of assumptions and uncertainty assessment. The commonly used risk assessment methods for chemical mixtures are whole mixture approaches and component-based approaches. The whole mixture approach is used when toxicological data are available for the mixture itself or toxicity data are available for a similar mixture or a sufficiently similar mixture that can be used as surrogate for the mixture of concern. Attendees will be equipped to use similarity and sufficient similarity for whole mixtures, understand the assumptions, and understand how to address the uncertainties. This course would be of interest to scientists who conduct mixtures risk assessment in different sectors, such as occupational health and safety, product safety, public health protection, or regulatory decision-making. Abstract # #1001 Assessing Human Health Risks from Whole Chemical Mixtures: An Overview. Novel Uncertainty Assessment Approaches for Evaluating Mixture of Concern, Sufficiently Similar Mixtures, or Similar Mixtures, Using Case Studies. The first instructor will present a series of databases and models that are both peer reviewed and free to use. The second instructor will cover new, consensus exposure predictions for instances where minimal exposure data are available. Each lecture will provide examples that can be easily modified by course attendees for specific chemical risk assessment applications. Students discuss with graduate students and academic program directors how to submit strong graduate school applications and succeed in graduate school, as well as the merits of specific graduate programs. Primary Endorser: Molecular and Systems Biology Specialty Section Other Endorser(s): In Vitro and Alternative Methods Specialty Section; Mechanisms Specialty Section Toxicological research and testing heavily depends on the application of cell and molecular assays to provide mechanistic insight into the effects of chemical exposures as well as model systems to overcome the constraints of in vivo human and animal exposure studies. Despite being powerful tools, these assays are not immune from the "reproducibility crisis" that has cast a considerable shadow over all fields of biomedical research. Improving the rigor, reproducibility, and physiological relevance of both traditional and high-throughput cellular and molecular methods is critical to protect human health, increase the efficiency of drug and consumer product development, and ensure the reliability of data used in chemical regulation. Recent reports in both the scientific and public literature have revealed a need for increased rigor in preclinical research and highlighted experimental design, reagents (including antibodies and cell lines), and data analysis as key challenges to study reproducibility. The goal of this course is to provide participants with "good research practices" for the rigorous development, optimization, implementation, and interpretation of robust in vitro toxicological assays for reproducible results using physiologically relevant models.
Generic 25 mg sildenafil overnight delivery
A fungal infection of the ear is called otomycosis External Ear infection are more commonly caused by: S erectile dysfunction humor generic sildenafil 75mg fast delivery. The following organisms may be found as commensals in the external ear: Gram positive Viridans streptococci other coliforms S erectile dysfunction 4xorigional order sildenafil 50 mg mastercard. Place it in container of Amies transport medium erectile dysfunction brands discount 100 mg sildenafil with visa, breaking off the swab stick to allow the bottle top to be replaced tightly. Label the specimens and send them with its request form to the laboratory Within 6 hours. Additional: Chocolate agar if the patient is a child: Inoculate the specimen on chocolate (heated blood) agar for the isolation of H. Incubate the plate in a carbon dioxide enriched atmosphere at 35-370c for up to 48 hours, examining for growth after overnight incubation. Incubate the plate anerobically for up to 48hours, checking for growth after overnight incubation. Sabouraud agar if a fungal infection is suspected Inoculate the specimen on sabouraud agar, and incubate at room tempreture for up to 6 days. Examine the specimen Microscopically Gram smear Make an evenly spread of the specimen on a shide. Small numbers of Gram positive cocci, streptococci, rods and also Gram negative rods may be seen in smears of ear discharges because these organisms form part of the normal microbial flora of the external ear. Additional: Potassium hydroxide preparation if a fungal infection is suspected Mix a small amount of the specimen with a drop of potassium hydroxide, 200g/l (20%W/v) on a slide, and cover with a coverglass. After 10 minutes, or when the preparation has cleared sufficiently, examine microscopically using 10x or 40x objective. Look for: Brnaching septate hyphae with small round spores, that could be Aspergillns speies Pseudohyphae with yeast cells, that could be candida specis (Gram positive) 140 Medical Bacteriology Branching septate hyphae, that could be a species of der matophyte Branching aseptate hypae, that could be a species of phycomycete. Inflammation of the the delicate membrane lining the eyelid and covering the eyeball conjunctiva is called conjunctivitis. It causes a severe purulent conjunctivitis that can lead to blindness if not treated. Herpes simplex virus can cause severe inflammation of the cornea (Keratitis) Commensals - That may be found in the eye discharges: Gram positive Viridans streptococci Staphylococci Gram negative Non-pathogenic neisseriae Moraxella speires Collection and transport of eye specimen Eye specimen should be collected by medical officer or experienced nurses. Using a dry sterile cotton wool swab, collect a specimen of discharge (if an inflant, swab the lower conjunctival surface). Make a smear of the discharge on slide (frosted-ended) for staining by the Gram technique. As soon as possible, deliver the inoculated plates and smear(s) with request form to the laboratory. Culture the specimen Routine: Blood agar and chocolate agar Inoculate the eye discharge on blood agar and chocolate (heated blood) agar. Loeffler serum slope if Moraxella infection is suspected: Inoculate the eye discharge on a loeffler serum slope. Microscopically examination Routine: Gram smear Look for: Gram negative intracellular diplococci that could be N. If found, a presumptive diagnosis of gonococcal conjunctioitis can be made A cervical swab from the mother should also be cultured for the isolation of N. Depending on the stage of development; If the inclusion body is more mature, it will contain - redmauve stiaing elementary particles. All these bacteria, with the exception of Hemophilus species, stain dark blue in Giemsa stained smear, but Haemophilus rods stain pale blue. Report the smear as "chlamydial inclusion bodies present" or "No chlamydial inclusion bodies seen". Carateum Virus: pox viruses and herpesviviruses Fungi: Ringworm parasite: Leishmania spps: onchocerca volvulus:D. Using a sterile dry cotton wool swab, collect a sample of discharge from the infected tissue.
