Patients exhibit a range of emotions post diagnosis including generic 40 mg cialis professional, mood changes such as:  Worry  Concerns with body image  Sadness  Sexuality  Anger  Employment  Fear of recurrence  Relationship issues 119 Responses of the clinician to emotional distress  Listen buy cialis professional 40mg low cost; ask open ended questions and show care, compassion and interest. Clinicians meeting anger may feel threatened, become defensive or, indeed, angry in response. These reactions are generally considered unhelpful as they are likely to result in an escalation of the patients anger (Cunningham, 2004). Develop a shared understanding of the experience, and develop shared goals from this point. After being told their diagnosis, approximately 20% of patients deny they have cancer; 26% partially suppress awareness of implementing death and 8% demonstrate complete denial (Greer, 1992). Strategies and communication skills for clinicians  Exclude misunderstanding or inadequate information  Determine whether denial requires management  Explore emotional background to fears  Provide information tailored to the needs of the patient and clarify goals of care  Be aware of cultural and religious issues  Monitor the shifting sand of denial as the disease progresses  Aim to increase a person’s self esteem, dignity, moral and life meaning (Greer 1992; Watson et al 1984; Erbil et al 1996; Schofield et al 2003) Useful Link for communication skills in cancer care: http://pro. Other Programmes to Support Cancer Patients Travel2Care scheme This scheme helps patients who are suffering from genuine financial hardship with travel costs due to travelling to a cancer centre. Care to drive programme Care to Drive is a volunteer-led transport initiative in which the Irish Cancer Society recruits and trains volunteers to drive patients to and from their chemotherapy appointments. Tax relief can also be claimed back on travelling costs for insured cancer patients. Dengue Fever 1 Introduction Dengue has a wide spectrum of clinical presentations, often with unpredictable clinical evolution and outcome. Reported case fatality rates are approximately 1%, but in India, Indonesia and Myanmar, focal outbreaks away from the urban areas have reported case- fatality rates of 3-5%. To observe for the following Danger signs and report immediately for hospital admission • Bleeding: - red spots or patches on the skin - bleeding from nose or gums - vomiting blood - black-coloured stools - heavy menstruation/vaginal bleeding • Frequent vomiting • Severe abdominal pain • Drowsiness, mental confusion or seizures • Pale, cold or clammy hands and feet • Difficulty in breathing Out -patient laboratory monitoring- as indicated • Haematocrit • White cell count • Platelet count 5. If not tolerated, start intravenous isotonic fluid therapy with or without dextrose at maintenance. If the haematocrit remains the same, continue with the same rate for another 2–4 hours and reassess. If the vital signs/haematocrit is worsening increase the fluid rate and refer immediately. Start with 5–7 ml/kg/hour for 1–2 hours, then reduce to 3–5 ml/kg/hr for 2–4 hours, and then reduce to 2–3 ml/kg/hr or less according to the clinical response. If the haematocrit remains the same or rises only minimally, continue with the same rate (2–3 ml/kg/hr) for another 2–4 hours. If the vital signs are worsening and haematocrit is rising rapidly, increase the rate to 5–10 ml/kg/hour for 1–2 hours. Reassess the clinical status, repeat the haematocrit and review fluid infusion rates accordingly. Reduce intravenous fluids gradually when the rate of plasma leakage decreases towards the end of the critical phase. This is indicated by urine output and/or oral fluid intake that is/are adequate, or haematocrit decreasing below the baseline value in a stable patient. Parameters that should be monitored include hourly vital signs and peripheral perfusion. Internal bleeding is difficult to recognize in the presence of haemo-concentration. First correct the component of shock according to standard guidelines with early use of packed cell transfusion. Further infusion of large volumes of intravenous fluids will lead only to a poor outcome. If the patient remains in shock and the haematocrit is elevated, repeated small boluses of a colloid solution may help. Secondly, dextrose is rapidly metabolized resulting in a hypotonic solution that is inappropriate for shock correction. Consider in severe shock  Aim for ≈ 20% fall in haematocrit and adjust fluid rate downwards to avoid overload  Aim for minimal acceptable urine output (0.

It results into significant morbidity ; affects precious growing period of a child, parental working days & possible negligence of other family members & also incurs formidable burden on scarce resources if treated improperly or inadequately. However, with the widespread availability of radioimaging techniques , fibrinolytic agents, safe & effective surgical procedures ( open or thoracoscopy ) the recent data is leading to more focused management guidelines though optimal management is still controversial (22). It could be localised or free collection of purulent material in pleural space as a result of combination of inoculation of bacteria & culture medium of pleural fluid. Stage 2 or Fibrinopurulent or Transitional phase ( 3 to 21 days ): There is deposition of fibrin in the pleural space leading to septations & formation of loculations. The presence of septations (fibrinous strands 17 in pleural fluid )doesn’t necessarily mean fluid doesn’t flow freely, although separate loculations will not communicate with each other. These solid fibrous or leather like peels may prevent lung re- expansion ( “trapped lung” ), impair lung function & create a persistent pleural space with potential for infection. It achieves debridement of fibrinous pyogenic material, breakdown of loculations, and drainage of pus from the pleural cavity under direct vision.

Objectives at the beginning of the chapters which are intended to guide the students in their study buy 20 mg cialis professional. Having the basic idea will help to have a better understanding on the pathology of specific part of the eye generic 20 mg cialis professional. At the end of this course, students are expected to know basic anatomy and physiology of the eye. Skin - has three important features - Thinnest, more elastic and mobile than skin else where in the body - Little or no subcutaneous fat under the skin makes it a good source of skin graft - Has an extremely good blood supply that is why wound heals well and quickly. Muscles Orbicularis oculi muscle • Important for closure of eye lid 3 th • Innervated by facial (7 cranial) nerve Levator Palpebrae • Elevator of eye lid. Tarsal plates - Are composed of dense fibrous tissue -Keep the eye lids rigid and firm -Contain meibomian glands, which open at lid margin, and makes oily secretion that forms a part of corneal tear film. Conjunctiva It is a thin mucous membrane which lines the inner surface of the eye lid and outer surface of the eye ball. The conjunctival epithelium is continuous with the corneal epithelium at the margin of the cornea, which is called limbus. Conjunctiva contains many small islands of lymphoid tissue especially in the fornix. Frontal bone Levator Palpebrae Orbicularis muscle Conjunctival fornix with Accessory lacrimal Skin glands Tarsal conjunctiva Eyelashes Tarsal plate with meibomian glands Fig 1. Wall of orbit- Roof Frontal bone and sphenoid bone Floor Zygomatic, maxillary and palatine bones Medial Ethimoid, frontal, Lacrimal and sphenoid bones Lateral - The strongest of all walls. Sclera Retina Anterior Choroid Chamber Cornea Fovea Optic nerve Pupil Lens Iris Suspensary ligament Ciliary body Optic nerve head Conjunctiva Vitreous body 1. Cornea - Is the main refractive media of the eye (75 % of refractory function of the eye). Iris - has central hole (pupil) through which light reaches the retina - consists of a vascular stroma covered by mesothelium anteriorly and by two pigmented layers of epithelium posteriorly. Its size is subject to various factors like aging, illumination, sleep, change of gaze, emotional status. Ciliary body - Triangular structure that is situated between the iris anteriorly and choroids posteriorly. Circulation of aqueous fluid Aqueous fluid is produced by ciliary process of ciliary body. It flows from the posterior Chamber along the pupillary opening to the anterior chamber. Finally it will be drained through the Canal of schlemn in the Trabecular meshwork to episcleral veins Stroma Endothelium Epithelium Trabecular meshwork Canal of Schlemn Iris Anterior Lens Chamber angle Posterior chamber Ciliary Processes Ciliary body Fig. The Choroids - It is network of blood vessels - The arteries and veins are located externally while capillaries are found internally. Have two layers I- Outer layer - Next to choroid, single layer of fragment epithelial cell. The electrical impulses produced by each rod or cone passes across synapses to the bipolar cell. Then the impulses are modified in various ways as they pass through the bipolar and ganglion cells. The nerve fibers from the ganglion cells travel in the nerve fibers layer on the surface of the retina to the optic disc and form the optic nerve. This is used to protect the macular cones from the dazzle of incident light, which occurs even with maximal pupillary constriction. Anterior chamber - Delineated anteriorly by the posterior corneal surface and posteriorly by iris. Posterior chamber - Limited anteriorly and laterally by the posterior iris surface and ciliary body and posterior by lens & vitreous body C. Vitreous space - Filled with vitreous humor - Transparent, roughly spherical and gelatinous structure occupying posterior 4/5 of the globe with volume of 4 ml. The lymphatic drainage of the medial eye lid is to sub mandibular lymph node and that of lateral one is to the superficial preauricular lymph nodes and then to deeper cervical lymph nodes. Ahmed 4 - Albert and Jakoboiec Principle and practice of ophthalmology 5 - Up to date - (C) 2001 - www. To give a clear idea about the approach to ophthalmic patients and specific examination techniques. At the end of the course the students are expected to know how to examine ophthalmic patients and use of certain ophthalmic instruments 2. Family history The main purpose of the history is to find out what exactly the patient is complaining. However it is always helpful to find out some background information about the patient e. Such information will indicate what vision the patient needs for work and for personal satisfaction. Major symptom of eye disease given • Disturbances of vision • Discomfort or pain in the eye • Eye discharge A. Disturbances of vision • The most common visual symptom • Can be sudden or gradual ¾ Blurring or reduction of vision ¾ Dazzling/glare/ – difficulty of seeing in bright light, may be caused by opacities in the cornea or lens ¾ Diplopia/ double vision/ ¾ Decreased peripheral vision – may be caused by various disorders in the retina, optic nerve or visual pathway pathology up to the visual cortex.

All enter hemorrhagic strains produce shiga toxin 1 and/ or shiga toxin 2 cialis professional 20 mg on-line, also referred to as Vera toxin 1 and Vera toxin 2 purchase cialis professional 40 mg without a prescription. The ability to produce shiga toxin was acquired from a bacteriophage, presumably directly or indirectly from shigella (7). This bacterium attaches itself to the walls of intestine, producing a toxin that attacks the intestinal lining (7). Clinical Features: ¾ Incubation period: The initial symptoms of hemorrhagic colitis generally occur 1 to 2 days after eating contaminated food, although periods of 3 to 5 days have been reported. Bacillus Cereus Pathogenesis: The pathogenic agent of Bacillus cereus food poisoning appears to be an entero toxin. This spore forming bacterium produces a cell–associated endo toxin that is released when cells die upon entering the digestive tract (4). Clinical features ¾ Incubation period: From 1 to 16 hours in cases where vomiting is the predominant symptom; from 6 to 24 hours where diarrhea is predominate (10,7). Clinical Features Typical symptoms include severe abdominal pain, cramps, diarrhea, vomiting, and nausea. The onset of symptoms is rapid (usually 1 to 8 hours) and of short duration (usually less than 24 hours). Pathogenesis It is primarily caused by botulinum toxin, which is a neurotoxin that binds to the synapses of motor neurons preventing neurotransmission. Clinical Features Symptoms of botulism occur within 18 to 24 hours of toxin ingestion and include blurred vision, difficulty in swallowing and speaking, muscle weakness, nausea, and vomiting. Without adequate treatment, 1/3 of the patients may die within a few days of either respiratory or cardiac failure. Lead poisoning Possible sources of contamination include residues migrating into foods from soldered cans, leaching from utensils, contaminated water, glazed pottery, painted glassware and paints. Toxicity occurs due to its affinity for cell membranes and mitochondria, as a result of which it interferes with mitochondrial oxidative phosphorylation and sodium, potassium, and calcium transport. Clinical Features Lead poisoning is characterized by abdominal pain and irritability followed by lethargy, anorexia, pallor, ataxia, and slurred speech, joint pain, peripheral motor neuropathy and deficits in short-term memory and the ability to concentrate. Convulsions, coma and death due to generalized cerebral edema and renal failure occur in most severe cases. Pathogenesis It is well absorbed by lungs and gastrointestinal tract, and excreted in small amounts in urine and/or feces. Clinical features Inhalation of mercury vapor manifests with cough, dyspnea, and tightness or burning pain in the chest. Acute high dose ingestion of mercury can cause nausea, vomiting, hematemesis abdominal pain, diarrhea and tenesmus. Major complications of mercury poisoning include: ¾ Respiratory distress, pulmonary edema, lobar pneumonia and fibrosis. Clinical Features: Major clinical features of arsenic poisoning include nausea, vomiting, diarrhea, abdominal pain, and delirium. Diagnosis of Food-borne Diseases A variety of infectious and non-infectious agents should be considered in patients suspected of having a food borne illness. However, establishing a diagnosis can be difficult, particularly in patients with persistent or chronic diarrhea, those with severe abdominal pain and when there is an underlying disease process. The extent of diagnostic evolution of food borne diseases can be based on history, clinical features, environmental assessment and laboratory investigations. Clinical Assessment The clinical diagnosis can be based on the clinical features discussed earlier in section 2. A case history may be important clue in determining the sources and causes of the diseases and the type of foods involved. Also, thorough physical examination should be done on any patient suspected to have food-borne disease. These investigations include macroscopic examination, microscopic examination, culture and biochemical tests, serology and toxicological tests. Different biological specimens such as stool, blood, liver aspirate, duodenal aspirate and muscle biopsy can be used for the investigation (16). Macroscopic Examination ¾ Routinely examine fecal specimens and identify the physical characteristics of the stools (color, consistency, presence of blood, and mucus). Because only a few eggs and cysts are usually produced even in moderate and severe infection, concentration technique should be performed. This substrate is acted on (usually hydrolyzed) by the enzyme attached to the antigen-antibody complex, to give a color change. Toxicological Tests Occasionally, the toxicology laboratory is asked to aid in the diagnosis of possible chemical intoxication by taking blood or urine sample from the affected individuals (22). Environmental Assessment It is important to conduct environmental assessment and collect environmental samples for suspected and potential causes of food borne illnesses especially of out breaks. The assessment may include survey of the source of the out–break with critical evaluation of: 35 ¾ Source of the suspected food; ¾ How the food is prepared including cleanliness of table and kitchenware; ¾ Personal hygiene and health status of food handlers; ¾ Sanitation of the food preparation and service premises; ¾ Storage of the food before and after its preparation; ¾ Presence of potential or actual contaminants; ¾ Availability of safe and adequate water supply; ¾ Availability of safe and adequate sanitary facilities; ¾ Type and quality of food storage, and service equipments including food contact surfaces. Sites of infection and areas of spread may include the farm of origin, dealers, markets, processing areas, wholesale or retail outlets to catering establishments, restaurants and domestic kitchens. General Management Approaches of Food-borne Diseases The management approach to food-born diseases depends on the identification of specific causative agent, whether microbial, chemical or other.
