A case report of Clarkson's disease: If you don't know it, you'll miss it

The systemic capillary leak syndrome (SCLS), also known as Clarkson's disease, is a rare disorder characterized by paroxysmal capillary hyperpermeability with a shift of plasma fluid from the intravascular to the interstitial space. A 35-year-old previously healthy woman was admitted with rapidly developing hypovolemic shock syndrome, rhabdomyolysis, and diffuse edema. Laboratory analysis revealed a severe hemoconcentration, renal insufficiency, and paraproteinemia. After exclusion of infection, allergy, burning or drug-induced conditions, the clinical presentation was consistent with the diagnosis of SCLS. Though this is a rare entity, the substantial morbidity and mortality associated with it necessitate the physician's awareness in order to provide timely therapy. This report is meant to enhance awareness of SCLS.

Do women with urinary incontinence really know where all the toilets are? The toilet paper

AIMS OF STUDY: Aim of this study was to determine if women with overactive bladder really do have a more detailed knowledge about toilets and their conditions in their vicinity in comparison to women with urinary stress incontinence and those without any urinary symptoms. PATIENTS AND METHODS: A questionnaire survey of 270 women from three symptom groups, those with stress incontinence, overactive bladder and controls without any bladder symptoms from an inner city area and two local towns. The knowledge of the three groups was compared and measured by a score assessed by the authors who had visited the toilets themselves. RESULTS: Women with overactive bladder are more likely to exhibit precautionary voiding prior to leaving home and have significantly more detailed knowledge about toilets in their neighbourhood. DISCUSSION: The overactive bladder seems to have a greater influence on behaviour and on quality of life than stress incontinence which could mean that they are more tortured by their symptoms.

Femoroacetabular impingement: radiographic diagnosis--what the radiologist should know

OBJECTIVE: The purpose of this article is to show the important radiographic criteria that indicate the two types of femoroacetabular impingement: pincer and cam impingement. In addition, potential pitfalls in pelvic imaging concerning femoroacetabular impingement are shown. CONCLUSION: Femoroacetabular impingement is a major cause for early "primary" osteoarthritis of the hip. It can easily be recognized on conventional radiographs of the pelvis and the proximal femur.

[What you always wanted to know about HbA1c]

Irreversible, nonenzymatic glycation of the haemoglobin A beta chain leads to the formation of haemoglobin A1c (HbA1c), a stable minor haemoglobin component with enhanced electrophoretic mobility. The rate of formation of HbA1c is directly proportional to the ambient glucose concentration. HbA1c is commonly used to assess long-term blood glucose control in patients with diabetes mellitus, because the HbA1c value has been shown to predict the risk for the development of many of the chronic complications in diabetes. There are currently four principal glycohaemoglobin assay techniques (ion-exchange chromatography, electrophoresis, affinity chromatography and immunoassays) and over 20 methods that measure different glycated products. The ranges indicating good and poor glycaemic control can vary markedly between different assays. At the moment values differ between methodologies and even between different laboratories using the same methodology. Optimal use of HbA1c testing requires standardisation. There is progress towards international standardisation and improved precision of HbA1c which will lead to all assays reporting results in a standardised way. Clinicians ordering HbA1c testing for their patients should be aware of the type of assay method used, the reference interval, potential assay interferences (e.g. haemoglobinopathies, chronic alcohol ingestion, carbamylation products in uraemia) and assay performance. And they should know that a variety of factors have been shown to directly influence HbA1c values, e.g. iron deficiency anaemia, chronic renal failure and shortened red blood cell life span.
