Early loss of colour vision and contrast sensitivity may be present due to hiv infection vomiting order genuine nemasole on-line involvement of optic nerve anti viral hand gel generic nemasole 100 mg on-line. Malingering—It is seen in persons who hope to antiviral medication for chickenpox purchase 100mg nemasole with mastercard gain some advantage by pretending to antiviral tincture nemasole 100 mg with amex be visually defective or handicapped. When one eye is said to be blind and there is absence of objective signs, following tests can be done. A prism is placed base downwards before the ‘good eye’ and the patient is asked to look at a light source. The Optic Nerve 351 It is frequently bilateral and has a chronic course with permanent visual deterioration. Pathogenesis There is degeneration of the ganglion cells of the retina specially in the macular region. Central vision is impaired so that there is difficulty in reading and doing near work. Fundus examination—It is normal or it may show slight temporal pallor of the disc. It involves several persons at a time consuming the wood alcohol from the same source. Administration of alkali—Soda bicarbonate is given by 5% intravenous drip or orally as there is acidosis. The clinical features include those of optic neuritis, optic atrophy and retinopathy. Fundus examination shows pale and atrophic disc with contracted retinal vessels and oedema. A mild pigmentary disturbance leads to the characteristic “bullseye” lesion in the macular area. There is widespread retinal atrophy with clumps of pigment and attenuated retinal vessels seen in the Chloroquine amblyopia later stage. There is increased risk of vascular occlusion particularly in women who are suffering from hypertension, migraine or other vascular diseases. Common causes of optic atrophy Pathogenesis There is destruction of nerve fibres along with overgrowth of glial connective tissue. Primary (Simple) Optic Atrophy the lesion is proximal to the disc so there are no signs of local inflammation. There is shallow, saucer-shaped atrophic cupping due to degeneration of nerve fibres. Secondary Optic Atrophy Etiology It follows any injury or direct pressure to the optic nerve from lamina cribrosa to the lateral geniculate body. Consecutive Optic Atrophy Etiology Extensive retinal diseases cause ganglion cell destruction as occurs in retinitis pigmentosa and occlusion of central retinal artery. Ischaemic Optic Atrophy Postneuritic optic atrophy Etiology It is due to the central retinal artery occlusion. Toxic Optic Atrophy It has been already discussed under toxic amblyopias (page 350). Glaucomatous Optic Atrophy It has been already discussed under glaucomatous optic disc changes (page 267). In complete or total optic atrophy, the person is blind with no perception of light. Visual field shows concentric contraction with depression of central vision in initial stages with or without scotomata. The prognosis is good because of the slow growth and peripheral situation of the tumour. Inferior crescent • this is a common form occurring due to incomplete closure of the embryonic fissure. Coloboma of the disc—There is a greater failure of the embryonic fissure to close. Medullated (Opaque) Nerve Fibres Normally the myelin sheaths of optic nerve stop at the lamina cribrosa. Occasionally patches of nerve fibres regain these sheaths after they have passed through the lamina cribrosa. The common causes of injury in the children include playing with bow and arrow, throwing stones, ball, sharp pointed objects like pen, pencil, stick, etc. An eye injury is an emergency and requires immediate medical or surgical treatment. There is great irritation and gritty feeling if the foreign body is embedded in the cornea. Foreign body is visible on the bulbar conjunctiva, limbus, cornea, sulcus subtarsalis and fornix by the naked eye, oblique illumination with a loupe or slit-lamp examination. Do not rub the eyes—It is very important as the foreign body may penetrate in the deeper tissues. If in the conjunctiva, it is picked up by a needle after application of local anaes Foreign body spud thetic. Foreign body spud—If in the cornea, it is gently scraped off with the foreign body spud with its blunt end. Sharp needle (sterilized)—If the foreign body has penetrated in the superficial layers of cornea, it is gently lifted by the sideways motion or by liver action of a sharp needle. Educative means are used such as “safety first” notices and lectures by the welfare officials in the factories. The burn injury can be caused by hot water, steam, hot ashes, explosive powder, molten metals, etc. These can cause considerable damage to the eye because they tend to penetrate deeper. They cause necrosis of the surface epithelium in a few seconds with occlusion of the limbal vasculature. This leads to a diminished vascularity of the anterior segment, corneal opacification and melting, cataract and symblepharon. These are less serious than alkalis burns because they coagulate the surface proteins and do not penetrate the eye. Poison gases—Lacrimatory gases, phosgene, mustard, gas, arsenicals and other agents are used in war. In holi festival (festival of colours), there is great danger of chemical injury to the eyes due to the presence of ‘mica’ in various coloured powders. A glass rod well-coated with a lubricant or ointment is swept around the upper and lower fornix several times a day to break and prevent the formation of adhesions. If cornea is not involved, steroid drops and ointments should be used to prevent symblepharon formation and to reduce congestion and chemosis of the conjunctiva. Conjunctivitis caused by lacrimatory gases is treated by irrigation with bland lotion, normal saline, 3% soda bicarbonate or clean water. Rupture—There is full-thickness wound of the blunt trauma eyeball due to blunt trauma 2. Laceration—There is full-thickness outside to thickness wound of the coats due to inside break in the ocular coats. Perforating injury—Both an entry and exit wound are present (earlier known as double perforation) the ocular trauma classification group has proposed a new classification system for mechanical injuries to the eye. Deep corneal opacity is due to the oedema of corneal stroma and folds in the Descemet’s membrane. Blood staining of the cornea is due to associated haemorrhage into the anterior chamber with raised tension. This may lead to subconjunctival dislocation, expulsion or dislocation of lens in vitreous cavity. Antiflexion of iris—In extensive iridodialysis, the pigmented portion of iris faces forwards. Retroflexion of iris—The whole iris is doubled back into the ciliary region (total inversion). Aniridia or irideremia—The iris is completely torn away from the ciliary attachment. It contracts and forms a minute ball which sinks to the bottom of the anterior chamber.
It is advisable to hiv infection rates homosexual discount 100mg nemasole wear a protective apron and hand protection; whether leather gauntlets or tongs should be used will be dictated by circumstances hiv infection through food order 100 mg nemasole visa. Such measures are recommended but it should be ensured that they do not precipitate a hazard as a result of loss of tactile sensitivity hiv aids infection rates uk discount nemasole 100mg otc. Splashes in eyes or on skin should be washed away immediately with copious quantities of water hiv infection rates white females generic 100 mg nemasole mastercard. To minimize risk of static electricity, laboratory coats of natural fibre rather than synthetic fabrics are preferred. It is important to neutralize any spillage on the coat immediately, since delay could result in the impregnated garment becoming a fire hazard. To prevent glass fragments from flying in the event of an explosion, use should be made of metal gauzes to screen reaction flasks etc. Whenever possible a stabilizer or diluent should be used and separation of the pure material should be avoided. In the event of fire, the area should be evacuated, the alarm raised and the fire brigade summoned. Only if it is clearly safe to do so should the fire be tackled with an appropriate extinguisher. Chemical engineering operations Many chemical engineering unit operations may be linked together in chemical processing. Melting with quiet burning is at one end of the spectrum; cracking, flashing-off or flaring are considered hazardous. Impact Impact sensitivity can be gauged by striking a few crystals of the compound on a metal last with the ball of a ball-pein hammer. Ignition, smoking, cracking or other sign of decomposition are considered hazardous. Hazard indicators Differential thermal include heats of decomposition in excess of 0. Observations such as decomposition with evolution of gases prior to ignition are regarded as potentially hazardous. Bomb calorimetry Use of oxygen and an inert gas enables the heat of combustion and the heat of decomposition to be evaluated respectively. The decomposition rapidly propagates through the entire mass for unstable diazo compounds; no such propagation is reported for stable versions. Heat transfer Convective heat exchange, natural or forced Radiant heat transfer. They are substances not classified as deflagrating or detonating explosives but exhibit violent decomposition when subject to heat.

Control access including vehicles • Segregate/seal drains • Appropriate gas/vapour/fume/pressure venting. Dependent upon the chemicals in-process, each of these may introduce a range of hazards. Above 500°C it reacts readily with oxygen and confined flammable mixtures explode violently if ignited Main hazards: fire, explosion, metallurgical problems arising from hydrogen attack Nitration Hazards arise from the strong oxidizing nature of the nitrating agents used. The explosive potential of chemicals liable to exothermic reaction should be carefully appraised. Monitoring Monitor temperature, pressure flow, composition, freedom from contamination and other appropriate properties of all streams where relevant. Consider automatic control Isolation Provide for isolation from upstream and downstream operations. Consider isolation for cleaning needs Contaminants Provide measures to remove unacceptable contaminants from feed materials, process streams and services. Avoid superheated liquids, which will flash-off, if practicable Allow for effects of over-/under-temperature, over-/under-pressure. Start-up/shutdown Provide for safe start-up, including purging if necessary Provide for safe shutdown: Normal By a trip On standby In various emergency situations, etc. Instrumentation Provide safety instrumentation in addition to process instrumentation Consider high–high and low–low alarms. The characteristics of some potentially hazardous reactions are summarized in Tables 7. Many processes require equipment designed to rigid specifications together with automatic control and safety devices. At or below 120 K, the permanent gases including argon, helium, hydrogen, methane, oxygen and nitrogen can be liquefied at ambient pressure as exemplified by Table 8. Any object may be cooled to low temperatures by placing it in thermal contact with a suitable liquefied gas held at constant pressure. Applications can be found in food processing, rocket propulsion, microbiology, electronics, medicine, metal working and general laboratory operations. Cryogenic technology has also been used to produce low-cost, high-purity gases through fractional condensation and distillation. Cryogens are used to enhance the speed of computers and in magnetic resonance imaging to cool high conductivity magnets for non-intrusive body diagnostics. These are prepared by cooling organic liquids to their melting points by the addition of liquid nitrogen. Unless strict handling precautions are instituted, it is advisable to replace the more toxic and flammable solvents by safer alternatives. Typical insulating materials include purged rockwool or perlite, rigid foam such as foam-glass or urethane, or vacuum. However, because perfect insulation is not possible heat leakage occurs and the liquefied gas eventually boils away. Uncontrolled release of a cryogen from storage or during handling must be carefully considered at the design stage. The main hazards with cryogens stem from: • the low temperature which, if the materials come into contact with the body, can cause severe tissue burns. Flesh may stick fast to cold uninsulated pipes or vessels and tear on attempting to withdraw it. The low temperatures may also cause failure of service materials due to embrittlement; metals can become sensitive to fracture by shock. The cryogens encountered in greatest volume include oxygen, nitrogen, argon and carbon dioxide. Liquid oxygen Liquid oxygen is pale blue, slightly heavier than water, magnetic, non-flammable and does not produce toxic or irritating vapours. Select storage/service materials and joints with care, allowing for the reduction in ductility at cryogenic temperatures. Glass Dewar flasks for small-scale storage should be in metal containers, and any exposed glass taped to prevent glass fragments flying in the event of fracture/implosion. Large-scale storage containers are usually of metal and equipped with pressure-relief systems. In the event of faults developing (as indicated by high boil-off rates or external frost), cease using the equipment. Provide a high level of general ventilation taking note of density and volume of gas likely to develop: initially gases will slump, while those less dense than air. Possibly provide additional high/low level ventilation; background gas detectors to alarm. With toxic gases, possibly provide additional local ventilation; monitors connected to alarms; appropriate air-fed respirators. Wear face shields and impervious dry gloves, preferably insulated and of loose fit. Wear protective clothing which avoids the possibility of cryogenic liquid becoming trapped near the skin: avoid turnups and pockets and wear trousers over boots, not tucked in. Prior to entry into large tanks containing inert medium, ensure that pipes to the tank from cryogen storage are blanked off or positively closed off: purge with air and check oxygen levels. If in doubt, provide air-fed respirators and follow the requirements for entry into confined spaces (Chapter 13). First aid measures include: Move casualties becoming dizzy or losing consciousness into fresh air and provide artificial respiration if breathing stops. In the event of ‘frost-bite’ do not rub the affected area but immerse rapidly in warm water and maintain general body warmth. Ensure that staff are trained in the hazards and precautions for both normal operation and emergencies.
