Pathogenesis (Color Plates 17 to 21): Atopic dermatitis is thought to result from a complex interplay of genetic, immune, metabolic, infectious, neuroendocrine and environmental factors; certain cytokines and chemokines mediate this infammatory process resulting in elevated IgE levels. Mechanical injury from trauma, infection, or scratching stimulates the local production of infammatory markers leading to the clinical lesions of eczema 2. Atopic dermatitis affects 15%?25% of children, with the peak prevalence between ages 6 months and 8 to 10 years b. Clinical presentations (Box 8-1): Acute changes include erythema, vesicles, crusting, and secondary infection. Porokeratosis Syphilis Lichen planus Generalized Yes Painful Yes Yes Graft-versus rash? Truncal, facial, and scalp involvement is common, with sparing of the diaper area b. Late childhood and adolescence: Lesions tend to be restricted to skin creases and hand dermatitis 4. Chronic disease: Bland lubricants, including petroleum jelly, Aquaphor, Eucerin, and vegetable shortening, are mainstays of therapy. Bathing time should be short (no more than 5 min); skin should be patted dry, not rubbed, before application of lubricant. Avoidance of triggers such as allergens, harsh detergents, products with alcohol, fragrances, and astringents is also very important b. Topical steroids: (1) Low and medium-potency steroid ointments once or twice per day in the most severely affected areas for eczema fares and for generally no more than 7 days. Severe fares may require a longer duration of therapy followed by a taper to lower-potency steroids. Even with low-potency steroids, special care is required in areas in which the skin is thin, such as the diaper area, groin, armpits, under the breasts, around the neck, and on the face. High potency topical steroids should generally be used in consultation with a dermatologist (2) Lubricants should be applied generously over topical steroid ointment c. May be used for short periods of uncontrolled eczema fares or for severe disease requiring hospitalization d. Antihistamines: May be used when pruritus causes scratching, thus exacerbating underlying eczema. Neither agent causes skin atrophy,12 allowing for safe alternatives for recalcitrant facial eczema, as well as possibly preventing the need for topical steroids. Complications17: Most common complications include blistering of lesions, bacterial infections, and eczema herpeticum See more information about eczema complications on Expert Consult, Chapter 8 B. Morphology: Characterized by chronic or recurrent eruptions of pruritic papules, vesicles, and wheals resulting from a hypersensitivity reaction to biting and stinging insects. Most commonly grouped in linear clusters and present on exposed areas with sparing of the genital, perianal, and axillary regions. Scarring and permanent hyperpigmentation and/or hypopigmentation in some patients, particularly in darkly pigmented individuals 2. Peak age range: 2?10 years, with most children developing tolerance by age 10 years. Prevention: Advise patients to wear protective clothing and use insect repellent when outside, launder bedding and mattress pads for bed mites, and maximize fea control for pets b. Pruritus control: Antihistamines if symptoms are acute and suggest a type 1 nature; not very effective in chronic stages. Topical steroids may also be used for acute lesions; extension into the dermis and fat may make these ineffective. Second-generation antihistamines such as cetirizine may be helpful for pruritus c. Ichthyosis (Color Plate 23) A group of scaling disorders consisting of fve major variants: congenital ichthyosiform erythroderma, lamellar ichthyosis, epidermolytic hyperkeratosis, ichthyosis vulgaris, and X-linked ichthyosis. There are also six separate ichthyotic syndromes, of which these lesions are a feature. Epidemiology: Infecting organism is Pityrosporum (Malassezia); commonly colonizes skin by age 4?6 months 2. Clinical presentation: Multiple small oval scaly patches that measure 1?3 cm in diameter in a raindrop pattern on upper chest, back, and proximal portions of the upper extremities of adolescents and young adults. Lesions appear light tan, reddish, or white in color; appear hyperpigmented in light-skinned patients and hypopigmented in darker-skinned patients 3. Treatment: Selenium sulfde and propylene glycol; rapidly clear infection; pigmentary changes may take a prolonged time to clear, and recurrence is common E. Clinical presentation: Patients typically present with annular patch or plaque with an advancing, raised, scaling border and a central clearing. Treatment: Topical treatment is often suffcient for treatment, but oral antifungals can be added for severe infections. Traditional topical antifungals include clotrimazole and miconazole, but newer antifungals such as butenafne and terbinafne have been shown to be more effective because of their stronger fungicidal properties. Topical treatment is recommended until the lesion resolves plus 1?2 additional weeks19 V. An anthropophilic organism with no known natural reservoir; persists for long periods on fomites such as hairbrushes, combs, furniture, stuffed toys, and clothing Chapter 8 Dermatology 215 b. Incidence is highest in African American children and second highest in Hispanic youths. This predisposition is not completely understood, but may be the result of the character of the hair follicle, tight braiding, or the use of pomades 2. Classic tinea capitis: Presents as one or more round to oval patches of partial to complete alopecia, with varying degrees of erythema. Scale is present, and the border is slightly raised and more erythematous than the central area b. A boggy, tender, edematous plaque or cluster of nodules with erythema; usually solitary and is frequently accompanied by cervical or occipital adenopathy and papular morbilliform eruption, classifed as an id reaction c. Seborrheic dermatitis-like pattern (most common): May produce minimal or no alopecia and show diffuse scaling over the scalp, with pruritus d. Pattern seen predominantly in African American children with tight braiding and constant pomade use; often resembles bacterial folliculitis, but bacterial culture is negative 3. Diagnosis: the presumptive clinical diagnosis may be confrmed by either direct microscopic examination or culture of scale (may be collected with a toothbrush on a culture plate or on a moistened culturette swab) 4. It is best taken with fatty food to promote absorption (see Formulary for dosage information). Standard references suggest 4?6 weeks of therapy, although 8?12 weeks may be required for eradication. Patients should be reevaluated monthly; repeat culture may be obtained 2 weeks before therapy is discontinued to document cure. Patients will often develop an eczema-like rash associated with the fungal infection (id reaction); not a drug reaction, and griseofulvin therapy should be continued19 b. Terbinafne (Lamisil granules) can be used for a 4-week treatment course and has been shown to be just as effective as an 8-week course of griseofulvin against Trichophyton infections; however, it is not as effective against Microsporum20 c. The use of sporicidal shampoos in addition to oral therapy promotes rapid elimination of spores, thus decreasing the contagion risk to family members and schoolmates. Clinical presentation: Common condition characterized by the sudden onset of asymptomatic, noninfammatory, round, bald patches located on any hair-bearing part of the body, most commonly the scalp. Course is irregular and unpredictable; most patients develop good regrowth of hair within 1 or 2 years 2. Treatment: Topical corticosteroids, topical minoxidil, tar preparations, anthralin, topical sensitizers, and ultraviolet light therapy. Likewise, systemic steroids should generally not be used because they do not alter prognosis. In adolescents and adults, hair loss often resolves over months to years; in younger children, the prognosis is more guarded C.
Muscae volitantes?These are black spots floating in front of the eye due to mood disorder webmd discount bupron sr line minute opacities in the vitreous mood disorder quotes buy generic bupron sr line. Asteroid hyalosis?These are unilateral spherical minute depression definition nice discount 150mg bupron sr with visa, white bodies of calcium soaps resembling snowball anxiety jaw muscle tension discount 150mg bupron sr amex. Synchysis scintillans?There is deposition of freely floating, highly refractive cholesterol crystals in the lower part of fluid vitreous. Amyloid degeneration?It is a rare bilateral systemic disease with deposition of amyloid in the vitreous and other parts of the body. Preretinal or subhyaloid haemorrhage?The haemorrhage occurs between the retina and the vitreous. The blood remains fluid, red in colour and moves with gravity forming boat-shaped figure in the macular area due to peculiar ring-shaped attachment of vitreous around the macula. Intravitreal haemorrhage?The haemorrhage may get absorbed or degenerate to form a white fibrous tissue mass. Investigations B scan ultrasonography is helpful in identifying fibrovascular proliferations on the retinal surface and associated tractional or rhegmatogenous retinal detachment. The eyes are bandaged so that there is minimum dispersion of blood in the vitreous. This allows the blood to settle down and helps in locating holes, tears or phlebitis. Vitrectomy?It is done after 3-6 months if no visual improvement takes place and when vision is reduced to only perception of light or hand movements. The vitreous may herniate only in the anterior chamber or may escape outside the eye. Updrawn pupil is usually seen due to attachment of vitreous bands to the pupillary margin and corneoscleral section. Aphakic glaucoma may occur at a later stage due to pupillary block or due to presence of vitreous in the anterior chamber causing angle closure. It is also useful for accidental vitreous loss which may occur during aphakic keratoplasty. Prophylaxis Intraocular pressure is kept low preoperatively by the administration of acetazolamide and application of digital pressure, Flieringa ring, pinky ball, etc. In addition to bacteria and fungi, vitreous abscess with intense eosinophilia may be seen with parasitic infections such as Taenia, microfilaria, Toxocara canis, etc. Shrinkage of vitreous (syneresis) the presence of white blood cells results in the laying down of fibrous connective tissue and capillary proliferation. Syneresis?There is collapse of the vitreous due to collection of synchytic fluid between the posterior hyaloid membrane and the internal limiting membrane of the retina. There is an optically clear space between detached posterior hyaloid phase and the retina. Complications these include retinal breaks, haemorrhage, vitreous haemorrhage, cystoid maculopathy, etc. Detachment of Vitreous Base and Anterior Vitreous this usually occurs after blunt trauma. There may be associated vitreous haemorrhage, anterior retinal dialysis and dislocation of lens. Vitrectomy or excising the vitreous is the most significant advancement in the surgical management of vitreous diseases. A patient is submitted to vitrectomy when his visual acuity is at least hand movements. Specific investigations, are done to confirm the diagnosis of the underlying disease. The Vitreous 253 Techniques the term vitrectomy? implies the cutting of formed vitreous gel which is responsible for producing various complications. All instruments perform vitreous cutting and aspiration under microscopic control with the help of fiberoptic illumination. This is performed through the limbus or a large corneal section after removal of the lens. Vitreous loss during lens extraction?Vitreous loss is managed by clearing the vitreous from the incision and the anterior chamber. It avoids both anterior segment and retinal complications as the approach is through the pars plana. Any opacity in the anterior segment such as after cataract and pupillary membrane. The Vitreous 255 Technique It is performed through a surgical microscope allowing coaxial illumination and fine movements by X-Y coupling. Special planoconcave lenses are placed on the cornea to provide a clear image of the posterior third of the eye. Through the third, a vitrectomy instrument for suction and cutting of the vitreous is inserted. Any abnormalities in the vitreous can be cleared bimanually under direct vision using the vitrectomy instrument and the endoilluminator as support when needed. Once the visibility of the retinal is restored, the cause for the vitreous disturbance is treated. Various substances have been tried to replace vitreous after vitrectomy such as; i. They are used as 40% mixture with air for restoration of normal intraocular pressure. Combining agents available for tamponade provide better support to superior and inferior retina simultaneously. The principal ocular structures concerned with it are the pars plicata part of the ciliary body, angle of anterior chamber and the aqueous outflow system. The shape of the ciliary body is like an isosceles triangle with its base forwards. The outer side of the triangle lies against the sclera with the suprachoroidal space in between. Ciliary muscles?These are flat bundles of non-striated muscle fibres which are helpful in accommodation of the lens for seeing near objects. Stroma?It consists of connective tissue of collagen and fibroblasts, nerves, pigments and blood vessels. Pars plicata?The anterior one-third of ciliary body (about 2 mm) is known as pars plicata. It is relatively avascular therefore posterior segment of the eye is entered through the pars plana incision 3-5 mm behind the limbus. Angle of Anterior Chamber It plays an important role in the process of aqueous drainage. The angle width varies in different individuals and plays a vital role in the pathogenesis of different types of glaucoma. Clinically the various angle structures can be visualised by gonioscopic examination. Aqueous Outflow System It includes the trabecular meshwork, canal of Schlemm, aqueous veins and the episcleral veins. Trabecular meshwork?It is a sieve-like structure through which aqueous humor gets filtered into the canal of Schlemm. Canal of Schlemm?This is an endothelial lined oval channel present circumferentially in the scleral sulcus. They leave the canal of Schlemm at oblique angles to terminate into episcleral veins. There is pressure difference of about 5 mm Hg between the anterior chamber and the episcleral veins so that the aqueous drains continuously in them. The Formation of the Aqueous Humour the aqueous humor is a clear watery fluid filling the anterior chamber (0. In addition to its role in maintaining normal intraocular pressure, it also plays an important role in providing nutrients and removing metabolites from the avascular cornea and lens. However, the chemical analysis of the aqueous humor indicated that ultrafiltration and secretion are involved in the formation of the aqueous humor.

In order to assist clinicians in providing advice to patients regarding the most effective type of exer cise intervention for chronic low back pain, an Discussion exploratory subgroup analysis was undertaken Based on the combined results of these moderate to which grouped exercise interventions by exercise high quality randomised controlled trials, exercise type and examined their efficacy. Based on the has a small but significant benefit for the treatment results of this analysis, a small but significant effect of non-specific chronic low back pain and is more was observed for the strength/resistance and coordi effective than conservative therapies. Although finding is consistent with the advice provided in our meta-analysis suggests these should be preferred current low back pain guidelines. However, no particular low back pain is associated with disturbance of modality showed consistent results, and the three muscle activation patterns and weakness and trials that displayed outcomes with statistical sig increased fatigability of both trunk and extremity nificance 51,53,57 used pilates, an individualised muscles. Some studies have shown cise programs showed no effect in reducing chronic that no single muscle is key to achieving lumbar low back pain. Prior studies70,71 have shown that spine stability62,63 and based on this, recommenda people with chronic low back pain have lower tions have been made for rehabilitation programs physical fitness levels than healthy subjects. The larger effect size associated with the guidelines72 recommend a cardiorespiratory pro strength/resistance programs may have been due to gram should be undertaken 3 to 5 times per week, the wide range of muscles trained and the improve for 20 to 60 minutes and that a 15 to 20 week time ments in muscle strength, power and functional frame is appropriate to evaluate the efficacy of an abilities seen after resistance training. Only two of the six trials included in the coordination/stabilisation exercise pro our analysis met these requirements. The use of grams in this review typically focused on strength measures of low back pain to determine treatment ening muscles considered to be essential for core efficacy in this review may also have affected the stability including the lumbar multifidus and trans outcome relating to cardiorespiratory exercise.

Anterior uveitis?The inflammation of the iris (iritis) and pars plicata of the ciliary body (cyclitis) depression definition and example buy 150mg bupron sr overnight delivery, i anxiety young child buy bupron sr 150 mg cheap. Anatomical classification?The International Uveitis Study Group has recommended the classification based on anatomical location of uveal tract anxiety yahoo answers bupron sr 150 mg generic. Intermediate uveitis?There is inflammation of pars plana part of the ciliary body and peripheral retina and underlying choroid depression sociology definition buy bupron sr without a prescription. There is associated inflammation of adjacent retina and hence the term chorioretinitis? is used. Clinical classification?Uveitis can also be categorized by the clinical courses as: i. Pathological classification?Uveitis can be further divided according to the pathological lesions which can be of two types: i. Inflammation is insidious in onset, chronic in nature with minimum clinical features. Non-granulomatous uveitis?It is usually due to allergic or immune related reaction. Endogenous infection?Organisms lodged in some other organ of the body reach the eye through the bloodstream. Allergic inflammation?It occurs in a sensitized ocular tissue which comes in contact again with the same organism or its protein (antigen-antibody reaction). Hypersensitivity reaction?It occurs due to hypersensitivity reaction to autologous tissue components (autoimmune reaction). Allergic (exudative or non-granulomatous)?It is of acute onset and short duration. It is characterized by the presence of fine keratic precipitates which are composed of lymphoid cells and polymorphs. Clinical features Features of low grade Features of acute inflammation inflammation i. There is severe neuralgic pain referred to forehead, scalp, cheek, malar bone, nose and teeth (as the iris is richly supplied by sensory nerves from the ophthalmic division of 5th nerve). Lacrimation and photophobia may be present (without any mucopurulent discharge) due to associated keratitis. Impaired vision?It is mainly due to hazy plasmoid aqueous and opacity in the media. Photophobia is due to pain induced by pupillary constriction and ciliary spasm because of inflammation. Circumciliary congestion?There is hyperaemia around the limbus which is dull purple-red in colour. There is plasmoid aqueous containing leucocytes, minute flakes of coagulated proteins and fibrinous network. Milky flare? or aqueous flare?Dust-like particles are seen moving in the beam of slit lamp similar to Tyndall effect. Aqueous flare grading +1 Faint Just detectable +2 Moderate Iris details clear +3 Marked Iris details hazy +4 Intense With severe fibrinous exudate Slit-lamp examination in acute iridocyclitis b. Keratic precipitates (kp)?The exudate tends to stick to the damaged endothelium in the lower part of cornea in a triangular pattern due to the convection currents in anterior chamber and effect of gravity. They are characteristic of granulomatous uveitis with predominance of macrophages. Hypopyon?In severe cases of iritis polymorphonuclear leucocytes are poured out which sink to the bottom of the anterior chamber forming hypopyon. Hyphaema?Blood in the anterior chamber rarely occurs due to spontaneous haemorrhage. It reacts sluggishly to light due to irritation of the third nerve endings in iris. Ectropion of uveal pigment is due to the contraction of exudates upon the iris so that the posterior surface of iris folds anteriorly. Anterior peripheral synechiae?The iris gets attached to the periphery of the cornea. Intraocular pressure may rise when 3/4 circumference or more of the angle of anterior chamber is blocked. Occlusio-pupillae or blocked pupil?Exudates organize across the pupillary area therefore the vision is impaired and there is associated raised tension. Total posterior synechiae?In severe cyclitis, the posterior chamber is filled with exudates which may organize tying down the iris to the lens capsule. Cyclitic membrane?In worst cases of plastic iridocyclitis, a cyclitic membrane may form behind the lens. Complicated cataract?There is typical posterior cortical cataract with bread crumb appearance and polychromatic lustre. Vitreous?Vitreous opacities due to leuco cytes, coagulated fibrin and exudates may be present in severe cases. Hypertensive iridocyclitis may be present due to increase pressure in dilated capillaries and outpouring of leucocytes. The sticky albuminous aqueous drains Acute iridocyclitis with difficulty thus raising the tension. Secondary glaucoma?It may occur as an early or late complication of iridocyclitis. Early glaucoma (Inflammatory glaucoma)?In active phase of the disease, presence of exudates and inflammatory cells in the anterior chamber may block the trabedular meshwork resulting in decreased aqueous drainage and thus a rise in intraocular pressure (hypertensive uveitis). Late glaucoma (postinflammatory glaucoma) is the results of pupil block (seclusio-pupillae due to ring synechiae formation or occlusio-pupillae due to organised exudates) not allowing the aqueous to flow from anterior to posterior chamber. Choroiditis?It may develop in prolonged cases of iridocyclitis owing to their anatomical continuity. Retinal complications?These include cystoid macular oedema, macular degeneration, exudative retinal detachment and secondary periphlebitis retinae. Investigations Series of tests should be done because of varied etiology of uveitis. Radiological investigations include X-rays of chest, paranasal sinuses, sacroiliac joints and lumbar spine. Modern broad-spectrum antibiotics which cross the blood-aqueous barrier are given in cases of infections. Atropine It is the most powerful, longest acting (2 weeks) and commonly used mydriatic and cycloplegic. Slit-lamp examination Normal Aqueous flare and kp Corneal oedema and anterior synechiae i. Thus, it also relaxes the ciliary muscle spasm which is always associated with iritis. It prevents formation of posterior synechiae and breaks down recently formed synechiae which are not firmly attached by dilating the pupil. In case of atropine allergy, other mydriatics like phenylephrine, cyclopentolate or tropicamide may be used. In milder cases weaker, short-acting agents such as cyclopentolate 1% or homatropine 2% thrice daily may be used. Dark glasses or an eyeshade may also be used to avoid glare, discomfort and lacrimation specially in sunlight. Heat Application Heat application in the form of hot fomentation or local dry heat is very soothing. Due to their anti-allergic and anti-fibrotic activity they reduce fibrosis and thus prevent disorganisation and destruction of tissues. It is better to use full strength topical steroids for 6 weeks to make sure that patient is not having side effects such as raised intraocular pressure. Rimexolone (Vexol 1%)?A new drug is being used in United States of America for anterior uveitis. Analgesics and Anti-inflammatory these are useful in relieving pain and discomfort. Antibiotics the modern broad-spectrum third generation antibiotics are of immense value particularly in fulminant cases of purulent uveitis. Although these are of not much use in allergic iridocyclitis, they provide an umbrella cover. These are safer as prolonged use of steroids may produce open angle glaucoma by reducing outflow facility, cataract and secondary infection with bacteria or fungi. These agents should be administered with great caution under the supervision of haematologist or an oncologist as they have adverse side effects or kidney, liver and cause bone marrow depression. Recently azathioprine, mycophenolate, mofetil, tacrolimus are used in unresponsive or intolerant patients.
