Patients' Perception of Bone and Tissue Excision, and the Size and Weight of Prostheses at Total Knee Arthroplasty.

The aim of this study is to ascertain patients' perception of the amount of bone and tissue excision and size and weight of their implanted prostheses at total knee arthroplasty (TKA). To our knowledge, no prior study in the English orthopaedic literature has analyzed these parameters against patient perception of TKA. In a prospective study of eight consecutive TKA (six primary and two single-stage revision TKA procedures) by a single surgeon, patients estimated the weight of their implanted knee.

Hereditary spastic paraplegia, bipolar affective disorder and intellectual disability: a case report.

This is a case report of a gentleman with an intellectual impairment who presented with both hereditary spastic paraplegia (HSD) and bipolar affective disorder (BPAD), a combination that has not yet been described in the professional literature. A limited number of articles have suggested an association between HSP and an organic personality disorder. We describe the case of a gentleman who was diagnosed with BPAD in his early adult life and displayed neurological symptoms of HSP at around the same time.

An evaluation of protein assays for quantitative determination of drugs.

We have evaluated the response of six protein assays [the biuret, Lowry, bicinchoninic acid (BCA), Coomassie Brilliant Blue (CBB), Pyrogallol Red-Molybdate (PRM), and benzethonium chloride (BEC)] to 21 pharmaceutical drugs. The drugs evaluated were analgesics (acetaminophen, aspirin, codeine, methadone, morphine and pethidine), antibiotics (amoxicillin, ampicillin, gentamicin, neomycin, penicillin G and vancomycin), antipsychotics (chlorpromazine, fluphenazine, prochlorperazine, promazine and thioridazine) and water-soluble vitamins (ascorbic acid, niacinamide, pantothenic acid and pyridoxine). The biuret, Lowry and BCA assays responded strongly to most of the drugs tested.
