What is the diagnosis? How would you treat? Slide 14 Erythema chronicum migrans classical immune-mediated skin lesion which occurs at the site of the bite in Lyme disease some weeks after the bite by the tick. (boriella burgdorferi infection) The tick bite leaves a red macule or papule which approximately later expands to produce a hot, painless annular/target lesion. Tx doxycycline Slide 15 Lyme disease often the first manifestation of Lyme disease = Lyme borreliosis spirochete Borrelia burgdorferi is transmitted by the bite of the deer tick Ixodes scapularis in the northeastern U.S. systemic borreliosis is a potentially serious disease, causing both acute and chronic symptoms such as fever, malaise, arthralgia, carditis, arthritis, meningitis, neuropathy, ataxia Slide 16 TROUSSEAUs SIGN This is a recurring thrombophlebitis characterised by successive crops of tender nodules in affected blood vessels. Different veins may be affected simultaneously or randomly. It denotes a thrombotic state and is associated with visceral malignancy, especially of the pancreas and lung. Thrombophlebitis migrans was first recognised by Trousseau in the diagnosis of his own pancreatic cancer. Slide 17 What is this? What causes it? What other signs would you look for? Slide 18 ANSWER Plummer vinson syndrome (Post cricoid web) Iron deficiency anaemia Koilonychia, pallor, atrophic mucous membranes, tachycardia if marked Tx balloon dilatation and iron supplements Pre-malignant!!!

Monitor Bp, lying and standing, JVP, chest Pulmonary OEDEMA Take blood for group and save, crossmatch. fluid should be run in as fast as possible; patient's response monitored. If the patient remains shocked, group specific or O Negative blood should be given as cross-matching may take up to 45 minutes. If the patient still fails to improve, internal bleeding should be sought. Following stabilisation, fluid infusion may be moderated according to urine production. Give blood to maintain Hb>8g/dl Slide 61 Hypovolaemia Haemorrhage aortic dissection, leaking AAA, splenic rupture Fluid loss - Diarrhoea, vomiting, polyuria,burns 3 rd space losses- acute pancreatitis, ascites Adrenal failure Slide 62 What is this x ray showing? what condition is this person likely to have? What are the complications of this condition? Slide 63 arachnodactyly MARFANS SYNDROME (AD) diff diagnosis homocystinuria -disorder of methionine metabolism OCULAR upward lens dislocation retinal detachment SKELETAL and MUSCLES arachnodactyly tall with disproportionately long legs and arms - the span of the arms is greater than the height pectus excavatum spinal abnormalities - spondylolisthesis, scoliosis SUFE generalised joint laxity with predisposition to flat feet or dislocation of patella or shoulder CARDIOVASCULAR dilatation of the aorta may aortic regurg, mitral regurg dissecting aneurysm of the aorta Mental development is normal. The average lifespan of an affected individual is 40 to 50 years. Slide 64 What is this and with what conditions is it associated? Slide 65 Dupuytrens contracture Liver disease Epilepsy/ treatment with phenobarbitone or phenytoin Peyronie's disease - penile fibrosis Family history trauma myxoedema diabetes mellitus hypercholesterolaemia AIDS Slide 66 What is this called? What conditions is it associated with?? Slide 67 Alopecia areata localised, round bald patches developing suddenly over one or two weeks, without any preceding symptoms. At the edge of the patch, there may be small, broken hairs with a tapering shaft - 'exclamation mark' hairs. autoimmune phenomenon Asssociations: thyroid disorders, vitiligo, diabetes. Slide 68 A diabetic patient developed this eruptionwhat is it? These are small rounded plaques with raised borders lying in a linear fashion over the shins. In late diabetic dermopathy these may present as pigmented scars. Slide 69 Diabetic dermopathy These are small rounded plaques with raised borders lying in a linear fashion over the shins. In late diabetic dermopathy these may present as pigmented scars. Slide 70 What is wrong with these chaps? Slide 71 Peyronies disease the penis becomes curved due to asymmetrical fibrosis in the fascia surrounding the corpora cavernosa. Curvature towards the affected side is increased during an erection making intercourse difficult and painful Assoc with dupuytrens contracture and premature atherosclerosis Slide 72 What is wrong with this chap? Slide 73 Winged scapula Long thoracic nerve injury The long thoracic nerve supplies the serratus anterior muscle. It may be injured as a result of pressure on the shoulder, either from a sudden blow or by prolonged carrying of heavy objects. It is often one of the nerves affected in brachial neuritis and may also be damaged in diabetes mellitus. Winging of the scapula results. Slide 74 Slide 75 Henoch schonlein Henoch-Schonlein purpura is a condition characterized by a widespread necrotizing vasculitis of arterioles and small capillaries. children aged 3 to 8 years are affected, boys more than girls, Abdo pain, arthritis (large joints) and glomerulonephritis 70% have haematuria and proteinuria, but the glomerulonephritis is often asymptomatic, conferring a good prognosis. The disease is usually self limiting. Bed rest and simple analgesics may be prescribed for arthropathy Slide 76 What is this? What aggravates this condition? How do you treat? Slide 77 psoriasis Made worse by stress, alcohol, b-blockers, infection Better in sunlight Tx emolients, dithranol, Vitamin D analogues, coal tar, keratolytics PUVA Methotrexate, cyclosporin Infliximab, Etanercept Slide 78 Slide 79 erythrodermic psoriasis Life threatening complication of psoriasis Plaques cover over 90% of the body surface. Problems with thermoregulation, septicaemia, dehydration and high output cardiac failure may occur. Slide 80 This middle aged man is very unwell and has lost weight He developed these slowly evolving itchy lesions What is the diagnosis? Slide 81 Mycosis fungoides Mycosis fungoides is a non-Hodgkin's lymphoma that arises from CD4+ T lymphocytes. It is a cutaneous lymphoma that characteristically affects middle aged males. It usually begins as an eczematous reaction and proceeds to form plaques, tumours and fungating ulcers. Erythroderma may occur which often is highly pruritic. Treatment - topical steroids, topical cytotoxic agents, PUVA or radiotherapy. Prognosis relates to extent and type of skin involvement - average survival in the early stage of this disease is at least 10-15 years (2) Slide 82 What has this young chap developed? Slide 83 Eczema herpeticum widespread HSV infection superimposed on pre-existing (often mild) atopic eczema. Widespread vesicles and erosions, fever, and malaise occur. treat with intravenous and topical acyclyovir broad spectrum antibiotics are added in to treat or prevent superinfection. It is necessary to scrupulously care for the skin and carefully monitor fluid and electrolyte balance. Prophylactic oral aciclovir is indicated for recurrent disease. Slide 84 Eczema herpeticum again Slide 85 What has this 72 year old man developed? What would you advise? Slide 86 Chronic venous insufficiency Wear thick socks Avoid bruising Raise legs up as often as possible Compression bandaging for ulcer Tx dermatitis, infection Slide 87 What is this? What are the main complications? Slide 88 Neurofibromatosis (2 types) von Recklinhausen's disease, peripheral or type I neurofibromatosis (AD) bilateral acoustic neurofibromatosis, central or type II neurofibromatosis Caf au lait spots commonly seen COMPLICATIONS: Nerve entrapment Peripheral nerve tumours neuropathy Slide 89 What is this? Slide 90 pemphigoid autoimmune blistering disorder characterized by large, tense, intradermal (subepidermal) blisters on an erythematous base. BLISTERS REMAIN INTACT. If in eyes- blindness Elderly affected, Women > men. it is more common than pemphigus treatments that aim to suppress the inflammatory process, e.g. corticosteroids, antibiotics (e.g. tetracyclines, sulphones) other immunosuppressive treatments aim to suppress the production of the pathogenic antibodies, e.g. high-dose corticosteroids e.g. prednisolone 30- 60 mg per day, azathioprine, methotrexate, cyclophosphamide and cyclosporin Slide 91 What is this? Slide 92 PEMPHIGUS blisters within the epidermis of both skin and mucous membranes. autoimmune basis? Peak onset is between 60 and 70 years of age. W>M In comparison, bullous pemphigoid is characterised by blister formation at the level of the basement membrane and not within the epidermis. Slide 93 Long standing asymptomatic lump. What is the likely diagnosis? Slide 94 Lipoma Treatment is for cosmesis and consists of local excision. Some individuals have multiple subcutaneous lipomata; a biopsy may be required to exclude neurofibromatosis in such patients. The patient with multiple, tender lipomata may have Dercum's disease. A rare complication of lipomata is a liposarcoma. Slide 95 What is shown at the arrow? Slide 96 Ascending lymphangitis spreading of infection from its focus along regional lymphatic vessels. Commonly, an abscess forms at the regional nodes. commonly due to Streptococcus pyogenes; less often, to Staphylococci. It presents as red blushes and streaks in the skin corresponding to the inflamed lymphatics. Treatment is bed rest with the affected limb elevated. Penicillin V and Flucloxacillin Permanent lymphatic obstruction may develop resulting in a persistent oedema. Repeated attacks cause chronic lymphangitis. Slide 97 What is this? It started life as a red macule. Slide 98 Erythema chronicum migrans Caused by Borrelia burgdorferi, Lyme disease is common in the northeast United States and in Wisconsin and Minnesota. It is carried by Ixodes spp. of ticks. The rash occurs in 2/3 of those infected, with a solitary lesion characteristic of Stage 1 disease, and multiple lesions characteristic of disseminated Stage 2 disease Slide 99 What is this associated with? Slide 100 Vitiligo is associated with Hypothyroidism Addisons disease diabetes mellitus pernicious anaemia Tx camouflage cream Slide 101 What does this 72 year old chap have? Slide 102 Basal cell carcinoma This is a locally invasive carcinoma of the basal layer of the epidermis. It almost never metastasizes but it may kill by local invasion. sunlight exposure the initial lesion is a small pearly-white nodule with visible (telangiectatic) blood vessels; early lesions may bleed and ulcerate and then heal again a red nodule forms which expands to leave a characteristic rolled edge with central ulceration ('rodent ulcer') Tx: surgery, local radiotherapy, cryotherapy, or curretage Slide 103 Think maybe he should have come to the doc sooner about this one Slide 104 What is this? Slide 105 Squamous cell carcinoma Squamous cell carcinoma (SCC) is a malignant tumour of the epidermis in which the cells, if differentiated, show keratin formation. basal cell carcinoma keratocanthoma malignant melanoma solar keratosis pyogenic granuloma infected seborrheic wart rapidly expanding painless, ulcerated nodule rolled indurated margin. Often the lesion may have a cauliflower-like appearance with areas of bleeding, ulceration or serous exudation. Metastatic potential surgery (+radio/chemo if advanced) Slide 106 What is this? What types exist and what features are characteristic in this lesion? Slide 107 Malignant melanoma superficial spreading (48%) nodular (23%) lentigo maligna (15%) acral lentiginous including periungual (6%) amelanotic melanoma Change in SHAPE, SIZE, COLOUR >5mm diameter, inflammation, bleeding, irritation Excision biopsy (1cm margin for every mm thickness) Slide 108 What is happening in this patients arm? They previosly had a simple ulcer there Slide 109 Marjolins ulcer (arm) cancer Slide 110 What is this condition? Slide 111 Peutz Jeghers Peutz-Jegher's syndrome (AD) multiple hamartogenous polyps of the gastrointestinal tract - most often in the small bowel but may occur affect any portion of the GI tract mucocutaneous pigmentation - mainly, of the lips, buccal mucosa, genitalia, hands and feet Patients often present with small bowel intussusception before the age of 10 years. The polyps themselves have a very low malignant potential. About 10-20% of patients develop gastrointestinal carcinoma but this is thought to arise from coexistent adenomas. Patients have an increased risk of developing carcinomas of the pancreas, lung, ovary and breast. Slide 112 What are these lesions? Slide 113 Lichen planus flat-topped shiny violaceous (pink/mauve/purple) typically they are seen on the inner aspects of the elbows, on the wrists, shins and sacral area and genitals Wickhams striae mouth lesion This is a condition of unknown aetiology characterized by intensely pruritic flat topped papules that are usually seen on the inner aspect of the elbows and wrists. The mucous membranes are often affected. Slide 114 What does this chap have? What complications is it associated with? Slide 115 Ehlers danlos Ehlers-Danlos syndrome (EDS) is a condition where abnormalities of collagen production result in bruising, wide scars, laxity of joints and hyperelasticity of the skin. Hernia MR/AR Aortic dissection pneumothoraces GI bleeds Slide 116 This 34 year old wool factory worker presented with thiswhat is it? Slide 117 Cutaneous anthrax Anthrax sheep wool Slide 118 What is this? Slide 119 tylosis Tylosis is a congenital hyperkeratosis with pitting of the palms - tylosis palmaris - and of the soles - tylosis plantaris. It is inherited as an autosomal dominant trait. In some cases, it is associated with oesophageal carcinoma. Treatment measures include the use of a keratolytic. Systemic treatment with retinoids may be used Slide 120 What is wrong with this chap? How would you diagnose it? Slide 121 Kaposis sarcoma Kaposi's sarcoma is a multicentric, malignant neoplastic vascular proliferation, characterised by the development of bluish-red nodules on the skin. Sometimes there may be widespread visceral involvement. It may metastasize to lymph nodes. occurs in immunocompromised patients (e.g. HIV positive patients, transplant patients) Diagnosis: skin biopsy Slide 122 What is this? Slide 123 keratoacanthoma Difficult to distinguish from SCC rapidly growing epidermal tumour that resembles squamous cell carcinoma both clinically and histologically. It is believed to arise from hair follicles. There is little evidence that keratocanthoma has malignant potential Trauma, viral infection, sun exposure, and chronic exposure to tar, pitch and petroleum have all been implicated as aetiologic agents. Surgical excision is thought to produce less scarring than leaving the lesion to resolve spontaneously. Slide 124 What are these? What are they associated with? Slide 125 Gottrons papules Gottron's papules are scaly, erythematous lesions affecting the dorsum of the hands, knuckles, and extensor surfaces of other small joints. They are characteristic of dermatomyositis. Slide 126 What does this patient have? With what is it associated? Slide 127 Heliotrope rash Polymyositis and dermatomyositis are systemic connective tissue diseases which are characterised by acute and chronic inflammation of striated muscle. In dermatomyositis there is an accompanying dermatitis. The limb girdle or proximal muscles are most severely affected but their bulk is preserved beyond that expected from their weakness: this is an important sign distinguishing this condition from a limb girdle dystrophy. The aetiology is unknown but there is an association with HLA-B8 and HLA-DR3. Dermatomyositis in males over the age of 60 years may be suggestive of an underlying systemic malignancy. Slide 128 This 33 year old woman presented with fever, tachycardia, chills, malaise and this hot tender lesion on her face. What is it? What is tx? Slide 129 erysipelas Erysipelas is a rapidly spreading Streptococcal infection of the skin and subcutaneous tissue characterized by cellulitis and lymphangitis. Streptococcus pyogenes fever, tachycardia, chills, malaise the infected area is red, hot, and tender e.g. red shiny plaque on face local oedema which produces a raised border that is clinically diagnostic the cellulitis spreads rapidly to involve uninfected skin careful examination may reveal an abrasion through which the streptococcus organism gained entry an incision within the infected area exudes a thin pus Tx: amoxicillin Slide 130 What is wrong with this chap? What could have caused it? Slide 131 Left CN III palsy TUMOUR, INFECTION, VASCULITIS, DEMYELINATION SAFE ANSWER FOR ALL NERVE LESIONS central lesions: tumours: due to direct invasion of the third nerve nucleus due to raised intracranial pressure vascular: caused by a brainstem lesion demyelination peripheral causes include: compressive lesions: tumour aneurysm, often the posterior communicating artery basal meningitis nasopharyngeal carcinoma orbital lesions e.g. Tolosa-Hunt syndrome infarction: often spares the pupillary reflex, when the condition is termed a "medical third nerve palsy" often caused by diabetes mellitus Slide 132 This xray and CT are showing the same sign what is it? Slide 133 Porcelain gallbladder Porcelain gallbladder is a calcification of the gallbladder believed to be brought on by excessive gallstones but more studies are necessary to determine the exact cause.calcification gallbladdergallstones Porcelain gallbladder often results in a diagnosis of gallbladder cancer. The association with the two is uncertain; gallbladder cancer is rare, but is almost always found with porcelain gallbladder. The prognosis is poor, in that the gallbladder is usually asymptomatic until the cancer has spread.gallbladder cancer Slide 134 A 53-year-old man presented with low-grade fever and abdominal pain. A tender, erythematous umbilical 3-cm mass is shown. Slide 135 Strangulated umbilical hernia In a strangulated hernia, the blood supply of the contents of the hernia, e.g. bowel or omentum, is cut off. It is commonest at the neck of the sac. The region becomes ischaemic and subsequently gangrenous. Gangrene can lead to perforation of the bowel with ensuing peritonitis. When a loop of gut is strangulated, there will also be intestinal obstruction. Slide 136 This 23 year old woman is complaining of rectal pain. She denies any other symptoms Slide 137 What is this xray showing? Patient presented with an acute abdomen with the sudden onset of severe upper abdominal pain, nausea and vomiting. Slide 138 Gallstone pancreatitis Slide 139 A 50-year-old man presented with a 2-day history of atraumatic right middle finger swelling, redness, and pain. There was tenderness and swelling of the proximal interphalangeal joint. ESR was elevated. The leukocyte count normal. Describe how you would investigate and manage this patient Slide 140 Septic arthritis URGENT ADMISSION!!! ASPIRATE!!!! blood cultures full blood count for leucocytosis erythrocyte sedimentation rate C-reactive protein aspiration of synovial fluid - usually purulent with a neutrophil count above 50,000 per mm3, and low glucose concentration anti-streptolysin O titre Tx flucloxacillin and amoxicillin empirically! Slide 141 A 65-year-old woman presented to the emergency department because a friend was concerned that the patient was having a stroke. The patient was asymptomatic other than complaints of a pestering nonproductive cough. What is wrong? Slide 142 Subconjuntival haemorrhage This presents as a bright red patch under the conjunctiva following rupture of a small conjunctival vessel. It may arise spontaneously, following slight trauma, or as a result of local congestion due to coughing or sneezing. In head injury, blood from a fracture at the base of the skull may travel through the floor of the orbit and into the subconjunctival space. The condition is usually unilateral. Recurrent or bilateral subconjunctival haemorrhage suggests hypertension or blood dyscrasias. Slide 143 A 28-year-old woman complained of a foreign-body sensation, pain and redness of the outer lower quadrant of her left eye of 2-day's duration. Slide 144 episcleritis unilateral in two-thirds of cases. It is benign and self-limited. 30% are associated with general medical conditions such as collagen disease, herpes zoster, gout and syphilis. There are two types - simple and nodular. Simple episcleritis is characterized by a very acute onset. It is mild, sectoral, recurrent and resolves rapidly. The nodular form presents as a localised, raised mobile area of inflammation near the limbus. The nodules may be single or multiple and usually recur. About 15% of patients develop a mild iritis. Episcleritis is distinguished from conjunctivitis by the localised response and the lack of palpebral conjunctival involvement. oral non-steroidal anti-inflammatory drug (NSAID). Slide 145 A 2- year-old girl presented with fever, erythema, and swelling of the left upper eyelid. There were no visual symptoms or proptosis. Slide 146 periorbital cellulitis The findings shown are suggestive of acute periorbital cellulitis, or more accurately, preseptal cellulitis, an infection confined to the soft tissues of the eyelid. Bacteriology of preseptal cellulitis includes those bacteria that cause sinusitis (Haemophilus influenzae, Streptococcus pneumoniae, Moraxella catarrhalis, S pyogenes); skin flora from trauma (Staphylococcus aureus and group A Streptococcus); and idiopathic (H influenzae type B, S pneumoniae). (L.S.) Slide 147 A 20-year-old man presented with a brief loss of consciousness following a fall from standing height. He had a brief lucid interval then became progressively less responsive. This is his CT scan Slide 148 Extradural haematoma The characteristic appearance of a CT of an extradural haemorrhage is of a biconvex, lozenge shaped area of increased density. Spread is limited by the adhesion of the dura to the skull. A midline shift with compression of the ipsilateral ventricle may be apparent. Slide 149 A 25-year-old man was brought to the emergency department after having been hit in the left lateral chest with a jet ski. He was short of breath and hypotensive. Slide 150 Tension pneumothorax Should not have obtained an Xray emergency situation Slide 151 A 37-year-old homeless man presented to the emergency department with a 3-week history of neck pain that had started after a motor vehicle accident Slide 152 Subluxation of c1 on c2 Cervical subluxation is a flexion injury. There is no bony damage but the soft tissues are extensively damaged and the posterior ligaments torn. The affected vertebra hinges forward on the one below, opening up the interspinous space posteriorly then falls back again. Radiologically there may be an increased gap between the spines of affected vertebra, but the film often appears normal - flexion radiology may be required to demonstrate the instability. Treatment is usually a collar for six weeks. However, if there is persistent instability a posterior spinal fusion may be required. Slide 153 What is wrong with this girlbe specific! Slide 154 Bells palsy It is a lower motor neurone palsy usually diagnosed by exclusion. Typically, presentation is with facial distortion, loss of taste, hyperacusis and a watery eye. Bell's palsy was previously considered as an idiopthic lower motor neurone nerve palsy but there has been increasing evidence to suggest that the main cause of Bell's palsy is latent herpes viruses (herpes simplex virus type 1 and herpes zoster virus), which are reactivated from cranial nerve ganglia Slide 155 Patient is asked to look left Slide 156 Right VI nerve palsy Tumour Trauma Demyelination Ischaemia (stroke) Raised intracranial pressure FALSE LOCALISING SIGN Slide 157 Slide 158 Left CN 9 palsy Uvula deviates away from the affected side Slide 159 Slide 160 Left CN 12 palsy Tongue deviates towards side of lesion Slide 161 What is wrong with this lil lady? Slide 162 Trochlear CN IV palsy Diplopia abnormal head posture - head tilted towards the normal side, face rotated towards the normal side, and the chin is depressed. The affected eye is higher than its fellow. positive head tilt test - affected eye moves higher when the head is tilted towards the affected side CNIV is thinnest and has the longest intracranial course damaged easily by stroke and trauma Slide 163 What is wrong with these miserable looking folk? Slide 164 Myasthenia gravis Myasthenia gravis is an acquired autoimmune disorder characterised by weakness, typically of the periocular, facial, bulbar, and girdle muscles. Associated with serum IgG antibodies to acetylcholine receptors in the postsynaptic membrane of the neuromuscular junction. Classically, the muscles are easily fatigued. It affects 5 people in every 100 000. Non-thymoma cases have a peak incidence at 10-30 years and again, at 60-70 years of age; those associated with thymoma have a peak incidence at 40-50 years of age. Slide 165 Diff diagnosis Lambert-Eaton syndrome - muscles are not fatiguable - contraction leads to increased strength - reflexes are diminished congenital myasthenia botulism motor neurone disease (MND) - note that eye is very rarely involved in MND Slide 166 Myasthenia gravis Exacerbated by: exercise, barbituates, steroids improvement in strength after administering a short-acting anticholinesterase drug, for example, edrophonium chloride. acetylcholine receptor antibodies Management oral anticholinesterase medication, e.g. pyridostigmine or neostigmine (symptomatic improvement). if there is life-threatening or respiratory weakness developing in treated patients, then this usually requires immediate control of the airway, treatment of any underlying infection, and a course of plasma exchange thymectomy - required if there is a thymoma because of the risk of local infiltration. Also occasionally undertaken in other non-thymoma patients with myasthenia immunosuppression with corticosteroids +/- cytotoxic agents is also highly effective in inducing remission of disease and may be necessary preliminary to surgery in patients with severe disease. plasma exchange Slide 167 Lambert eaton Lambert-Eaton myasthenia is a presynaptic myasthenic syndrome characterised by impaired release of acetycholine from nerve terminals. 60% of patients have small cell lung carcinoma. Electromyography shows increased evoked potentials after repeated galvanic stimulation (the opposite occurs in myasthenia gravis). Symptoms improve with exercise Slide 168 Slide 169 Right sided horners syndrome slight ptosis pupillary miosis: due to paralysis of the sympathetically innervated Muller's muscle which normally dilates the pupil anhydrosis over the forehead Pancoasts tumour, carotid body tumour infection, vasculitis, demyelinating disease MS Slide 170 What is wrong with this chap? Ignore the white thing I dont know what that is Slide 171 hydrocephalus Communicating hydrocephalus obstruction to CSF flow from outside the ventricular system, usually in the subarachnoid space. All the ventricles show a generalised dilatation on a CT scan. It is safe to perform a lumbar puncture Non-communicating hydrocephalus obstruction to CSF flow within the ventricular system. Fluid accumulates proximal to the site of the blockage causing dilation. Slide 172 Management of hydrocephalus The cause of hydrocephalus should be eliminated if possible - e.g. colloid cysts of the 3rd ventricle, intraventricular meningioma, other obstructive causes. Otherwise, relieve pressure by shunting, or if the patient is rapidly deteriorating, by draining the ventricle directly. Endoscopic third ventriculostomy has become a more recent, and important, treatment option for occlusive hydrocephalus associated with aqueductal stenosis or space-occupying lesions of or around the posterior third ventricle and upper brainstem (1,2): this procedure appears to be more successful in adults than in young children it is efficacious in both previously shunted and non shunted patient complication and mortality rates compare favorably with those for shunts has also been increasingly used as an alternative treatment option for shunt complications Lumbar puncture may be used to relieve pressure in an acute communicating hydrocephalus. Slide 173 NPH Normal pressure hydrocephalus is a form of communicating hydrocephalus in which the intracranial pressure, as measured by lumbar puncture, is normal or intermittently raised. Failure to reabsorb CSF is compensated by reduced production. gait apraxia progressive dementia with memory loss sphincter disturbance resulting in incontinence Slide 174 What has happened here? What are the risk factors for this? Slide 175 L Middle cerebral artery ischaemic stroke Hypodense (dark) area on CT No midline shift Modifiable Risk factors for stroke smoking diabetes mellitus diet: high salt intake high fat intake low potassium intake low vitamin intake excess alcohol intake morbid obesity low physical exercise low body temperature cholesterol Non-modifiable risk factors increasing age male gender Afro-Caribbean descent positive family history of stroke Slide 176 Slide 177 Haemorrhagic stroke Note the high-density haemorrhage within the low density of the oedematous, infarcted region in the right hemisphere. Haemorrhage is evident from its onset on CT scanning. Slide 178 What is this?? What factors predispose to this condition? How would you manage? Slide 179 Subdural haemorrhage The characteristic picture of a CT scan of a subdural haemorrhage is one of a biconcave, concentric shaped, area of increased density spreading around the surface of the cerebral hemisphere. The contralateral ventricle may dilate owing to obstruction at the foramen of Munro. After 10-20 days, the subdural haematoma becomes isodense with brain. Later it becomes relatively hypodense. Slide 180 Subdural haematoma Subdural haemorrhages result from rupture of cortical bridging veins. These connect the venous system of the brain to the large intradural venous sinuses and lie relatively unprotected in the subdural space. any factor that stretches the bridging veins: cerebral atrophy, e.g. elderly low CSF pressure after shunting, for example for long- standing hydrocephalus or a fistula alcoholism coagulation disorder or anticoagulation therapy patients in whom conscious level is depressed: evacuate haematoma through 2-3 burr holes, and irrigate cavity with saline nursing in the head down position is recommended to prevent recollection patients in whom conscious level is not depressed: consider conservative measures - steroid treatment over several weeks Slide 181 How do you diagnose and treat this condition? Slide 182 Multiple myeloma a malignant neoplasm of plasma cells that arises in the bone marrow.

The procedure is as for an inguinal hernia - open the sac, inspect the testis for abnormalities, ligate and divide the patent processus vaginalis. In adults, primary hydrocoeles may be treated: conservatively - reassure the patient and provide a scrotal support. by aspiration - use a sterile needle and syringe. Clear, pale yellow fluid should be drained; fluid that is bloodstained suggests trauma or other underlying pathology. Following aspiration, the testis should be palpable. A sclerosant such as phenol may then be injected to stop fluid from reaccumulating, otherwise, periodic aspiration may be necessary. A hydrocoele should not be tapped if there is any suspicion of tumour - in the case of a tumour, aspiration may result in spread of malignant cells. by operation - if the diagnosis is in doubt, the hydrocoele is large, or fluid repeatedly reaccumulates after drainage. Once the fluid has been removed, the testis is examined for abnormalities. Slide 329 Slide 330 Neuropathic ulcer (diabetes pt) Slide 331 What is this? How would the patient who has had this removed have been investigated initially? Slide 332 Ruptured appendix Acute appendicitis is usually a clinical diagnosis full blood count - leukocytosis is generally present urea and electrolytes - assessment of dehydration pregnancy test serum amylase - if pancreatitis suspected abdominal radiology - helpful to distinguish: volvulus intussusception renal stones (90%) gallstones (10%) localised ileus Generally, urine analysis is unhelpful in differentiating appendicitis from a urinary tract infection. There is no place for barium enema in the diagnosis of appendicitis. Occasionally, ultrasound and CT scanning are used to investigate suspected appendicitis where the story is atypical.

Slide 345 Marasmus Marasmus is failure to grow associated with emaciation and fair appetite. It may be defined in terms of weight, for example less than 60% of that expected for age. Marasmus generally occurs in infants up to one year. In the developed world it is found in infants who are born undernourished or are recovering from a severe chronic illness, especially those affecting the bowel. In developing countries this condition commonly is associated with failure of lactation due to poor nutrition of the mother. Note that marasmus is an adaptive response to poor nutrition. Slide 346 A 77 year old man presents with his 4 th episode of rectal bleeding. The blood is a mixture of fresh blood and clots. The bleeding was severe enough to require a 4 unit blood transfusion. Barium enema was normal. Colonscopy showed this lesion Slide 347 Angiodysplasia Colonic angiodysplasia is a common cause of acute or chronic rectal bleeding and iron deficiency anaemia. Angiodysplasias are tiny - 1-5 mm in diameter - hamartomatous capillary lesions in the colonic wall which produce bleeding out of proportion to their size. They are believed to be acquired, possibly as a result of tension on the veins where they pass through the muscularis. colonscopy: may visualise lesion Treatment: electrical coagulation via the colonoscope resection of segment of colon if the above is unsuccessful Slide 348 This baby presented with severe diarrhoea, alopecia, FTT and a rash over the mucocutaneous junction.
