May spread through Haversian and Volkmanns canal system to form a subperiosteal abscess (requires drainage) In adults order bentyl 10mg amex, haematological spread less common bentyl 10 mg without prescription. Also cancellous bone of vertebral bodies, may compression fracture Eg: sluggish blood flow easy thrombosis following trauma predisposes to infection (esp staph aureus) Pathology: Inflammatory response oedema compromise vascular supply necrosis spread of infection through cortices pus under periosteum shearing of periosteum further disruption to blood vessels Causative organisms: Under one year: staph aureus, strep agalactiae, E coli. Tb and Candida in high risk groups Complications: Spread of infection septicaemia, joint infection Fracture, abscess formation Chronic osteomyelitis in 5 20% of cases Subacute osteomyelitis: Focal rather than systemic response to infection. Differential includes bone tumour and stress fracture Chronic osteomyelitis: Usually delayed or inadequate treatment. Brodies abscess: abscess surrounded by sclerotic bone due to organisms of low virulence Treatment: sequestrum must be removed, may require repeated surgery. P aeruginosa Discitis: inflammation of the lumber disc, usually < 8 years Pelvic osteomyelitis: pain referred to the abdomen, buttock or leg. If lumber or thoracic vertebrae may hunchback deformity Pyogenic infections of the hand Usually history of trauma Paronychia: common infection of periungual tissues, usually by Staph Aureus Felon: deep infection of the pad of the finger. Usually Staph aureus following puncture wound Cellulitis: Strep Pyogenes infection Suppurative flexor tenosynovitis: Infection of flexor tendon sheaths Presentation: Swollen finger with painful motion. Sporotrichosis common Metabolic Bone Disease Osteoporosis: bone matrix reduced in amount but normally mineralised (ie bone mass due to loss of both protein matrix and Ca in equal proportions) Osteomalacia: normal amount of bone matrix but deficient mineralisation (ie Ca) Both will appear on x-ray as osteopenia (poverty of bone) Bone Metabolism Osteoblasts: Synthesise osteoid: normally this is a thin layer as the time between matrix deposition and mineralisation is short. Number of vertebral fractures and resulting disability unknown of those > 80 going to hospital with a fracture dont return to their previous residential status Pathogenesis: rd Bone is constantly turning over. Around menopause will loose 6 10% of bone mass, then returns to gradual decline Trabecular bone (20% of skeleton) turnover 8 times that of cortical bone (80% of skeleton). Use Singh Index of number of trabecular groups present (6 = good, 1 = bad) Also thinning and attenuation of the cortices Fracture risk a combination of density (which we can measure) and structure (which we cant) By the time they present with a fracture, osteoporosis is usually advanced Severity depends on: Peak bone mass. Also genetic and geographic predisposition Gross: enlarged bone with thick cortices Micro: irregular trabeculae with numerous osteoclasts and plump osteoblasts, jigsaw pattern Prognosis: Progressive bone deformity and micro fractures, anterior bowing of the femur. Arthritis due to deformed joints Osteosarcoma in 5 10% of those with severe disease Investigations: X-ray: early radiolucency. Rare to involve the extremities Types: Conventional: eg diaphysis or metaphysis of long bones. Grossly, pearly blue/white colour of cartilage Secondary to multiple exostosis in chondrodysplasia Dedifferentiated Treatment: tend to metastasise late (to lung and other bones) attempt local excision and replacement with prosthesis Prognosis: Grade 1 and 2 80 90% 5-year survival, Grade 3 (rare) 40% 5-year survival. Local or distant metastasis may occur up to 20 years later Osteosarcoma (Osteogenic Sarcoma) Proliferating malignant spindle-cell stroma producing osteoid After multiple myeloma, it is the most common primary malignant bone tumour 50 60% of cases are near the knee (either distal femur or proximal tibia) Types: Conventional osteosarcoma: Most common. Differential is chondrosarcoma suspect if large bone in an older patient, erosion of the cortex or suspicious histology Chondroblastoma: benign chondroid neoplasm at the end of long bones during teens Osteogenic tumours: produce osteoid: Osteoid osteomas: Rare. X-ray: radiolucent central zone surrounded by opaque sclerotic bone Osteoblastoma: Roughly speaking, an osteoid osteoma that is > 1. High local recurrence, rarely metastasises Fibrosarcoma Malignant tumour of fibroblasts (ie collagen producing cells) Occurs in any connective tissue but more common in the extremities and middle aged Fibrosarcoma of the bone is rare.

If rules are broken (eg threats 10mg bentyl, etc) terminate the interview Interviewing tips: Is it wise to interview them at all? Basis in medical model Axis 2: personality disorder or traits and mental retardation cheap bentyl 10 mg visa. A short-term maladaptive reaction to a stressor (ie impairs social/occupational function or causes distress). Difficult to determine in dual diagnosis (substance related + non- substance related). Yerkes Dobson Curve (1908): moderate levels of anxiety can improve performance, but performance improvement plateaus and then falls with anxiety. May have limited symptom attacks Found across anxiety disorders and in non-anxious population Panic Disorder: Recurrent and unexpected panic attacks. Situationally-bound panic attacks are characteristic of social or specific phobias, although situationally-predisposed panic attacks are frequent in Panic Disorder Catastrophic misinterpretation of bodily sensations/mental events (eg has palpitations and thinks theyre having a heart attack). Fear visible anxiety symptoms Probability and cost of negative evaluation is over-estimated Early onset Leads to avoidance of social gatherings, public travel, etc Epidemiology: 6 month prevalence is 2 per 100, more females, onset in teens through to 35 social isolation Aetiology:? Aim is to elucidate these Identify and alter core conflicts Drug Treatment Benzodiazepines: may be useful for the short term or acute treatment of acute stress reactions. These prevent noticeable symptoms (eg blushing or shaking), which are typically interpreted catastrophically by individuals. Treating withdrawal: change to diazepam (greater dose flexibility), reduce dose by 10% every 2 4 weeks. Eg how do you feel about yourself, have you blamed yourself for things, do you feel guilty? Key difference between grief and depression is whether they themselves feel worthless or not Also review risk factors: Prior history of major depressive episode or suicide attempt. Previous episode 50% lifetime risk of recurrence Family history of mood disorder or suicide attempts. Its usually multifactorial regardless of cause may well need a multi-factorial approach to management Subgroups Subgroup Essential Features Implications Psychotic Depression Hallucinations and/or delusions More likely to become bipolar than non-psychotic types (esp under 25s). May be misdiagnosed as schizophrenia Melancholic Depression Loss of pleasure and lower mood Indicative of more severe (typically in morning), marked depression. Maybe misdiagnosed as agitation, significant weight dementia if cognitive impairment changes and inappropriate guilt or psychomotor retardation are prominent Atypical Depression Various: overeating, oversleeping, Common in younger people. May weight gain, mood still reactive to be misdiagnosed as a personality events, anxiety symptoms, disorder. Summer episodes may also occur Epidemiology and Aetiology Lifetime risk of depression in women is 20% Female: Male is 2:1, but in younger cohorts an in male depression is bringing the ratio down to 1.
