Answer Her mild normochromic-normocytic anaemia was most likely related to her cytotoxic cancer therapy. She was not iron defi- cient, and using iron and erythropoietin in combination for a haemoglobin 10g/dL is well justified. Treatment with erythropoietin and iron should be stopped, and her blood pressure monitored over 8–12 weeks. If hypertension is solely related to the erythropoi- etin therapy, her blood pressure should normalize and no further treatment will be required. In retrospect it may have been prudent to have more closely monitored her ery- thropoietic therapy and once her Hb 12g/dL stopped it as this may have avoided her neurological event.

Hamamelis: This remedy can help when varicose veins are large and sore, and very weak and easily damaged, with a tendency to bleed. Normally when you swallow, the lower esophageal sphincter, which is a circular band of muscle around the bottom of the esophagus, relaxes to allow food and liquid to flow down into your stomach. If this valve becomes weak- ened or relaxes when it shouldn’t, stomach acids can flow up into the esophagus, causing heartburn. When stomach acids continually reflux upward, it can cause irritation and in- flammation of the lining of the esophagus, which is known as esophagitis. This can cause chest pain after eating, difficulty swallowing, and breathing problems. The most commonly used classes of drugs in- clude the following: • Alginic acid forms a protective seal at the top of the stomach to prevent acid reflux. Examples include Losec (omeprazole), Pantoloc (pantoprazole), and Pre- vacid (lansoprazole). These products are well tolerated; side effects are rare and include headache and dizziness.

She should be referred to a nephrologist for long-term follow-up of her renal failure cialis extra dosage 100 mg, and plans should be made for renal replacement therapy cheap cialis extra dosage 100 mg without a prescription. Clinical trials are starting of vasopressin receptor antagonists which show promise at inhibiting cyst growth order cheapest cialis extra dosage. The patient’s children should have their blood pressure checked and later be screened by ultrasound. This gene encodes for the protein polycystin which is a membrane glycoprotein that probably mediates cell–cell and/or cell–matrix interactions. Her proximal interphalangeal joints and metacarpophalangeal joints are swollen and painful with effusions present. Rheumatoid arthritis is a chronic, systemic inflammatory disorder principally affecting joints in a periph- eral symmetrical distribution. The peak incidence is between 35 and 55 years in women and 40 and 60 years in men. The acute presentation may occur over the course of a day and be associated with fever and malaise. More commonly, as in this case, it presents insidiously, and this group has a worse prognosis. Rheumatoid arthritis characteristically affects proximal interphalangeal, metacarpophalangeal and wrist joints in the hands, and metatarsophalangeal joints, ankles, knees and cervical spine. As the disease pro- gresses damage to cartilage, bone and tendons leads to the characteristic deformities of this condition. Extra-articular features include rheumatoid nodules, vasculitis causing cutaneous nodules and digital gangrene, scleritis, pleural effusions, diffuse pulmonary fibrosis, pul- monary nodules, obliterative bronchiolitis, pericarditis and splenomegaly (Felty’s syn- drome). In patients with lond-standing rheumatoid arthritis, renal infiltration by amyloid may occur. Differential diagnosis of an acute symmetrical polyarthritis • Osteoarthritis: characteristically affects the distal interphalangeal as well as proximal interphalangeal and first metacarpophalangeal joints. These usually cause an asymmetrical arthritis affecting medium and larger joints as well as the sacroiliac and distal interphalangeal joints. This patient should be referred to a rheumatologist for further investigation and manage- ment. If there has been joint damage, the X-rays will show subluxation, juxta-articular osteoporosis, loss of joint space and bony erosions. A common site for erosions to be found in early rheumatoid arthritis is the fifth metatarso- phalangeal joint (arrowed in Fig. The pain settled for a period of 6 months but it has returned over the last 10 months. She describes it as a tight or gripping pain which lasts for anything from 5 to 30 min at a time. It can come on at any time, and is often related to exercise but it has occurred at rest on some occasions, particularly in the evenings. It makes her stop whatever she is doing and she often feels faint or dizzy with the pain. Detailed questioning about the palpitations indicates that they are a sensation of a strong but steady heart beat. In her previous medical history she had her appendix removed at the age of 15 years. At the age of 30 years she was investigated for an irregular bowel habit and abdominal pain but no specific diagnosis was arrived at. Two years ago she visited a chemist and had her cholesterol level measured; the result was 4. In her family history her grandfather died of a myocardial infarction, a year previously, aged 77 years. Examination On examination, she has a blood pressure of 102/65 mmHg and pulse of 78/min which is reg- ular. There is some tenderness on the left side of the chest, to the left of the sternum and in the left submammary area. On the basis of the information given here it would be reasonable to explore her anxieties and to reassure the patient that this is very unlikely to represent coronary artery disease and to assess subsequently the effects of that reassurance. It may well be that she is anxious about the death of her grandfather from ischaemic heart disease. From a risk point of view her grandfather’s death at the age of 77 with no other affected relatives is not a rele- vant risk factor. She has expressed anxiety already by having the cholesterol measured (and found to be normal). She has a history which is suspicious of irritable bowel syndrome with persistent pain, irregular bowel habit and normal investigations. Ischaemic chest pain is usually central and generally reproducible with the same stimuli. The associated shortness of breath may reflect overventilation coming on with the pain and giving her dizziness and palpitations. The characteristics of the pain and associated shortness of breath should be explored fur- ther. Asthma can sometimes be described as tightness or pain in the chest, and she has sea- sonal rhinitis and a family history of asthma. Gastrointestinal causes of pain such as reflux oesophagitis are unlikely in view of the site and relationship on occasions to exercise. The length of the history excludes other causes of acute chest pain such as pericarditis. The problem of embarking on tests is that there is no simple screening test which can definitively rule out significant coronary artery disease. Too many investigations may reinforce her belief in her illness and false-positive findings do occur and may exacerbate her anxieties. However, if the patient could not be simply reassured it might be appropri- ate to proceed with an exercise stress test or a thallium scan to look for areas of reversible ischaemia on exercise or other stress. A coronary arteriogram would not be appropriate without other information to indicate a higher degree of risk of coronary artery disease. History A 30-year-old woman is brought up to the emergency department at 2 pm by her hus- band. She has a history suggestive of depression since the birth of her son 3 months earlier. She has been having some counselling since that time but has not been on any medication. The previ- ous evening about 10 pm she told her husband that she was going to take some pills and locked herself in the bathroom.
