  • Your GCSE maths program has had a big impact on my revision for the better. You have made everything really simple to understand while still keeping all the necessary information. This is vital to my revision as I can quickly understand the key concept of that type of question and then I can apply it to some practice questions, thus saving me time. Your other book �How To Maximise Your Result In Every GCSE Exam� has greatly helped me in all of my other subjects as I can revise effectively which frees up my time and in class tests I have noticed a significant improvement from getting B and C grades to now getting A and A* grades. Thank you very much for these guides, I wish I had found them sooner! ▲▲▲

  • I was always one of those students who were top of the class for maths during my KS3 years. However, we didn't have maths lessons for around 6 months in year 10, so I fell behind rapidly, and I was getting below average for my GCSE mocks. This package has really boosted my knowledge in a matter of only two weeks! I am vastly improving in maths and I am confident, given that I follow Jeevan's principles, I will achieve an A* in GCSE maths... In the end I achieved an 'A' grade in GCSE maths (summer 2014). I was a little disappointed in myself. However, considering the circumstances, I think I did pretty well. I am now taking A-Level maths at a grammar school and wanted to thank you for helping me along the way. You have inspired me to do well in this subject and I'm sure my 'A' grade will definitely help me to study Veterinary Medicine at a top University. Once again, thank you so much! ♥♥♥

Nephrological assessment

  2. 2. Clinical history: introduction • In nephrology, as in all branches of medicine, a competent clinical assessment is crucial. This should incorporate symptoms and signs: • Arising locally from the kidneys and urinary tract. • Resulting from impaired salt and water handling. • Caused by failing renal excretory and metabolic function. • Relating to a systemic disease, causing or contributing to renal dysfunction.
  3. 3. Con.. Several additional factors need to be considered: • Asymptomatic patients often require assessment, following the discovery of an abnormal BP, urinalysis, or GFR. • Symptoms, signs, and investigation findings are organized into clinically useful syndromes • Biochemistry, radiology, and/or histopathology are almost always required for accurate diagnosis (although a thorough clinical assessment will lessen over-reliance on expensive and potentially invasive tests). • Diagnosis is often suggested by treatment, e.g. cessation of a nephrotoxic drug or restoration of adequate circulatory volume.
  4. 4. Past medical history • Urinary tract problems as a child (e.g. infections, nocturnal enuresis). • Previously documented renal or urinary tract disease of any kind. Ask specifically about infections, stone disease, and, in ♂ , prostatic disease. • Hypertension. When diagnosed? Who is responsible for follow-up? Current and historical treatment? Level of control? Self-monitoring with home BP monitor? • Cardiovascular risk factors or disease (e.g. IHD, CVA, PVD, dyslipidaemia). • Other relevant systemic disease (e.g. diabetes mellitus, connective tissue disorder, gout, inflammatory bowel disease, sarcoidosis). • Insurance or employment medicals can provide invaluable historical benchmarks. Can they recall a past BP check or providing a urine specimen? Have they had blood tests in the past?
  5. 5. Clinical history: symptoms and social history Local symptoms of urinary tract disease • Pain: • Loin pain. • Ureteric colic. • Suprapubic pain. • Haematuria. • Change in urine appearance. • Changes in urine volume: • Polyuria. • Oliguria and anuria.
  6. 6. Cont.. • Lower urinary tract symptoms (LUTS): • Obstructive (voiding) symptoms: — Impaired size or force of the urinary stream. — Hesitancy or abdominal straining. — Intermittent or interrupted flow. — Post-micturition dribble. — A sensation of incomplete emptying. — Acute retention of urine. • Storage (fi lling) symptoms: — Nocturia. — Daytime frequency. — Urgency. — Urge incontinence. — Dysuria.
  7. 7. Social history • Smoking: general CV risk in (and progression of) CKD, renovascular disease, urothelial malignancy ( 7 4-fold risk), pulmonary haemorrhage in Goodpasture ’ s disease. • Physical activity. • Occupational history: risk factors for urothelial malignancy.Hydrocarbon exposure has been implicated in glomerular disease, particularly anti-GBM disease. • Hepatitis and HIV risk factors. • A patient ’ s understanding of their kidney disease should be evaluated, and they should be encouraged to be involved in decisions about their care.
  8. 8. Cont.. • Renal diseases are often chronic disorders, incurring appreciable social morbidity. Factors, such as social isolation, accommodation, and work situation, are hugely important. In ESRD, social circumstance will exert an important influence on choice of, and ability to cope with, a particular dialysis modality. Livelihood may also be affected — one of the goals of RRT, wherever possible, should be to keep an individual in employment. Quality of life must never be forgotten amidst all the blood tests.
  9. 9. Review of systems May provide clues to an underlying systemic condition, such as connective tissue disorder or vasculitis. • Skin rashes. • Photosensitivity. • Mouth ulcers. • Painful, stiff, or swollen joints. • Myalgia. • Raynaud ’ s phenomenon. • Fevers. • Night sweats. • Thromboembolic episodes. • Red or painful eyes. • ENT: • Sinusitis. • Rhinitis. • Epistaxis. • Hearing loss. • Sicca symptoms (dry eyes, dry mouth). • Haemoptysis. • Hair loss. • Paraesthesiae.
  10. 10. Clinical history: drug, treatment, and family • Drug and treatment history • The importance of the drug history cannot be overstated — it will often tell a story of its own. 2 Ask candidly about compliance. • Antihypertensive therapy — past and present. Any important tablet intolerances or side effects. • Analgesics — ask specifi call about common NSAIDs (by their over-the-counter names, if necessary). Then ask again. • Any ‘one-off ’ courses of therapy that may not be mentioned as part of regular treatment, e.g. recent antibiotics (interstitial nephritis). • Oral contraceptive ( increase BP). • Steroids, immunosuppressive agents — type and duration. • Non-prescription, recreational (cocaine, IVDU), and herbal medicines. • Current or historical exposure to important nephrotoxic drugs
  11. 11. Family history • Essential hypertension: more common if one or both parents affected. • Diabetes mellitus (types 1 and 2): more common if close relative affected. Inherited kidney disease e.g PKD, Alport syndrome, IGA neuropathy etc..
  12. 12. Clinical history: additional factors • Decreased libido and impotence are extremely common in both ♂ and ♀ with CKD. • Irregular menses and subfertility are frequently encountered in ♀. Amenorrhoea is common in ESRD. • Previous pregnancies and any complications (UTI, proteinuria, i BP, pre- eclampsia). Miscarriages, terminations? Were infants healthy and born at term? • In CKD, maternal and fetal outcomes are importantly related to GFR, degree of proteinuria, and BP. • Cytotoxic drugs used in the treatment of glomerular disease can l premature menopause in ♀ or infertility in ♂ . This may influence treatment in a ♀ of childbearing age. Pre-treatment sperm banking can be offered in ♂ . • Risk factors for sexually transmitted disease when appropriate (HIV, hepatitis B and C can all cause glomerular disease).
  13. 13. Dietary history • Changes in appetite and weight. Dietary habits (alcohol, vegan, ethnic diet, protein or creatine supplements). Dietary advice is an important part of the management of many renal disorders ( i BP, AKI, CKD, the nephrotic syndrome, stone disease, dialysis).
  14. 14. Ethnicity and renal disease IgA nephropathy: Caucasians and certain Asian populations (China, Japan, and Singapore). • Diabetic nephropathy: black, Mexican American, Pima Indian (a native American tribe in Southern Arizona, beloved of epidemiologists and geneticists). An increasing problem in the immigrant Asian population in the UK. • SLE: Asian and black patients (and more aggressive disease). • Hypertension and hypertensive renal failure: black patients. • In the UK, the incidence of end-stage renal disease (ESRD) is 7 3 x higher in South Asian and black patients than in Caucasians.
  15. 15. Physical examination/clinical assessment • General inspection • Short stature • (CKD in childhood) • Weight • Pallor • Brown-yellow skin hue • ‘Sallow’ complexion • Hearing aid/hearing impairment • (Alport’s syndrome) • SVC obstruction • Evidence of past or present • haemodialysis access • (e.g. tunnelled lines, • scars from previous • dialysis lines, AV fistula)
  16. 16. Mouth • Fetor • Oral hygiene (SBE) • Gum hypertrophy • (ciclosporin) • Oral candida • (immunosuppression)
  17. 17. Face • Periorbital oedema
  18. 18. Hands • Metabolic flap • (severe uraemia) • Shortening of distal • phalanges + pseudoclubbing • (severe hyperparathyroidism) • Raynaud’s • Sclerodactyly • Calcinosis • Systemic • sclerosis

  26. 26. Retina • Hypertension • Diabetes mellitus • Vasculitis • Cholesterol emboli
  27. 27. Abdomen • Scars • ? Tenckhoff catheter • Ascites • Palpation: • Loin tenderness • Palpable kidney(s) • Palpable bladder • Transplant kidney • (right or left iliac fossa) • Abdominal bruit • Rectal (prostate) • Pelvic exam
  28. 28. Legs • Peripheral pulses • Oedema • Femoral bruits • Restless legs
  29. 29. Palpating the kidneys • The kidneys are generally only palpable in very thin patients. • The right kidney is more accessible than the left. Place the left hand posteriorly in the loin and the right hand on the abdomen lateral to the umbilicus. • On deep inspiration, the lower pole may be palpable by pushing the right hand gently inwards and upwards. • The normal kidney surface usually feels firm and smooth. ‘Balloting’ the kidney refers to palpation whilst pushing up firmly from behind. Using this technique, it may be possible to gently‘bounce ’ an enlarged kidney back and forth between the hands.
