The ‘older’ antihista- mines such as promethazine and diphenhydramine are quite effective tricor 160mg lowest price cholesterol vs cholesterol ester, but have a hypnotic effect precluding driving or using machinery order tricor 160 mg visa cholesterol test blood fasting. Newer antihistamines such as foxfenadine discount tricor 160mg with visa cholesterol levels of foods, astemizole buy generic tricor 160 mg cholesterol test uk nhs, cetirizine and loratidine are also effective, with less hypnotic effect. A few patients obtain increased benefit by adding an H2 antagonist such as cimetidine to the H1 antagonist already being administered. Where the condition is life threatening, intravenous hydrocortisone should be used. The face and upper limbs are preferentially involved, and the buccal mucosa is often involved in severely affected patients. The disorder starts acutely and usually lasts less than 2 weeks, although crops of new lesions often develop in the first few days. Non-steroidal anti- Mononuclear inflammatory cells collect at the dermoepidermal junction and inflammatory drugs fluid collects beneath the epidermis. Where Herpes simplex there is serious systemic disturbance, systemic steroids may be given. Sally, aged 27, thought that is Histoplasmosis was the curry she had had the previous night. Within 2 days, she had developed Coccidioidomycosis a widespread rash – particularly over her arms and upper trunk. The rash began to improve Ultraviolet irradiation after 12 days, but the disorder had made her feel tired and ill. It was thought to Ulcerative colitis and be erythema multiforme – in all likelihood precipitated by an attack of labial Crohn’s disease herpes simplex some 2 weeks before the onset. Sarcoidosis Brucellosis Annular erythemas Ulcerative colitis and Crohn’s disease Leprosy There are several disorders that are marked by the appearance of erythematous rings, which usually gradually enlarge and then disappear. Generally their signifi- cance is uncertain, but one, known as erythema gyratum repens, signifies the presence of an underlying visceral neoplasm (see page 281) and another, ery- thema chronicum migrans, indicates the presence of Lyme disease. Autoimmune disorders These disorders are also known as the collagen vascular disorders and the con- nective tissue diseases. In general terms, the immune system of an individual with 77 Immunologically mediated skin disorders Figure 6. In most of the disorders in this group, the inflammatory process seems to involve the small blood vessels in particular (vasculitis). These antinuclear factors may be intimately involved in the pathogenesis of the disease. The 5-year mortality has been variously estimated to be between 15 and 50 per cent, dependent on the organ systems affected and the pace of the disease. Pathology and laboratory findings Affected skin shows oedema, degenerative change in the basal epidermal cells and a tight cuff of mononuclear cells around the small blood vessels (Fig. Unexposed, uninvolved skin has deposits of immunoprotein – immunoglobulin G (IgG) or IgA – in about 60 per cent of patients at the dermoepidermal junction, detectable by direct immunofluorescent methods. Haematological find- ings include a normochromic, normocytic anaemia, a neutropenia, a lymphope- nia and a thrombocytopenia. Treatment Patients with active, progressive disease may require systemic steroids to suppress the inflammatory process. Immunosuppressive agents such as methotrexate, azathioprine and cyclosporin may also be needed. Clinical features Irregular, red plaques appear on light-exposed skin of the face, scalp, neck, hands or arms (Fig. The plaques develop patchy atrophy with patchy hypopig- mentation and hyperpigmentation, whereas other areas are thickened and warty. Where these do not cope with the dis- ease, hydroxychloroquine (200–400 mg per day) is often helpful. Caution must be exercised concerning the possible, although rare, toxic effects of this drug on the retina. Systemic steroids, the oral gold compound auranofin, cyclosporin and acitretin are other drugs that have been used successfully. In this auto- immune disorder, the fibroblast is stimulated to produce new collagen. When other organ systems are involved, the disorder affects the vasculature as well as fibro- blasts, and Raynaud’s phenomenon, renal involvement with glomerular disease, gut involvement with dysphagia and gut hypomobility, a rheumatoid type of 80 Systemic sclerosis polyarthropathy and skin stiffening are all seen (Table 6.

This causes a characteristic beak-like facial appear- stiffness ance, with narrowing of the mouth (Fig. Glomerulosclerosis and In more rapidly progressive systemic sclerosis, there may be more serious vas- renal insufficiency cular disease affecting the fingers, resulting in tissue necrosis and even the loss of Hypertension portions of the digits. Renal or pulmonary disease may eventually cause the death of the patient – the 5-year mortality rate of this disease being 30 per cent or more. Some improve- ment can be obtained by skilful management of the Raynaud’s phenomenon, and occasionally with penicillamine and immunosuppressive treatment with steroids and azathioprine or cyclosporin. It is mostly a disease of young adults, but involvement of the face and scalp in children pro- duces an ‘en coup de sabre’ deformity. Histologically, there is marked replacement of the subcuta- neous fat with new collagen, which has a pale, homogenized appearance. Lichen sclerosus et atrophicus It is not certain whether or not this is a form of morphoea. Small, irritating, whitish areas occur on the genitalia or around the anus or, less commonly, elsewhere over the skin. It is then known as balanitis xerotica obliterans and may cause discomfort and paraphimosis. There is a characteristic pathological picture in which there is intense oedema in a subepidermal band. A particularly characteristic sign is the presence of a mauvish ery- thema on the upper lids and around the eyes, likened to the colour of the heliotrope flower (Fig. On the backs of the hands, the erythema affects the paronychial folds and the skin over the metacarpals (Fig. There is proximal myositis, which causes pain and tenderness as well as pro- found weakness. If progressive, pharyngeal and respiratory muscles are affected and the condition becomes life threatening. The vasculitis group of diseases There are several disorders in which the major focus seems to be on the vascula- ture, with the kidneys, respiratory system, joints and skin apparently being primar- ily involved. The rash is both urticar- ial and papular, and particularly marked on extensor surfaces. It is also quite def- initely purpuric in that it cannot be ‘blanched’ by pressure with a microscope slide (Fig. Polymorphonuclear cells and fragments of polymorph nuclei are seen around small damaged blood vessels (leucocytoclastic angiitis). Cramping abdominal pain and malaena occasionally develop as a result of submucosal haemorrhagic oedema. Acute glomerulonephritis causes microscopic haematuria when renal involvement is mild, but oliguria and renal failure in a very few severely affected patients. Pathology and pathogenesis The cause is unknown, but hypersensitivity to streptococcal antigens may play a role in some patients. Immune complexes formed from streptococcal antigens and antibodies are believed to be deposited in endothelium, initiating the reaction. Histologically, collections of polymorphonuclear leucocytes and fragments of their nuclei are found around small blood vessels in the dermis (leucocytoclasis) alongside oedema and some bleeding.

On its fourth turns, coiling around a central bony lateral surface is the opening of the oval axis called the modiolus.

Ductus Cochlearis (Scala Media) The membranous duct lies in the bony canal of cochlea. The basilar membrane stretches from the osseous spiral lamina to the spiral ligament, which is a thickened endosteum on the outer wall of the bony canal. Continuous with the spiral liga- ment are the cells richly supplied by blood vessels and capillaries on the outer bony wall called stria vascularis. The scala media or ductus cochlearis ends as a blind tube, dividing the bony cochlear canal into two passages, the upper chamber called scala vestibuli and lower passage known as scala tympani. The two passages communi- cate with each other at the apex of the modiolus through a narrow opening called the helicotrema. The scala vestibuli commu- nicates with the middle ear through the oval window that is closed by the footplate of stapes. The scala tympani communicates with the middle ear through the round window Figs 2.
