Care should be taken when evaluating a biochemical test to consider the disease, whether a fasting state is required, whether there are diurinal variations, and medication or supplement intakes that may influence the laboratory results. For example, a low ferritin value is not only an indication of potential iron deficiency, but may also be low because of protein calorie malnutrition. For example, serum albumin is often decreased because of inflammation and wasting rather than low dietary intake of protein. Serum Proteins Visceral proteins are proteins synthesized in the liver that circulate in plasma (12). These visceral proteins are also acute- or negative-phase proteins and change according to stress and inflammation. They include urinary creatinine, serum creatinine, and urinary 3- methylhistidine. These indices are sometimes used to assess protein and muscle status, but they are rather nonspecific (12,13). Many of the acute- and negative-phase reactants are used to assess the short-term visceral protein status in individuals. This section focuses on albumin and transthyretin because they are the most common biomarkers for protein used in clinical practice. Serum albumin is commonly used in clinical settings to assess protein status in individuals, although it is of only limited utility because it is affected by many other factors, including the presence of inflammation. Although it is true that serum albumin decreases with protein restriction, it changes little with energy restriction (12). It has a relatively long half-life of about 20 days and it changes only slowly (12). Low levels of serum albumin are associated with liver disease, pregnancy, increased capillary permeability, and overhydration. Transthyretin is a transport protein that binds with thyroxin and retinol-binding protein (12). It is another negative acute-phase reactant, and decreases in response to stress and infection, but it is also altered by zinc status (12). The advantages to using transthyretin are its short half-life, which is about 2 days (12,13), making it more sensitive to changes. However, it also has all of the disadvantages that have been described for serum albumin, including lack of specificity and high cost (12). Creatinine is found primarily in the muscles and is sometimes used as an indicator of muscle mass and adequate energy status. Serum creatinine is 22 Part I / Introduction to Rheumatic Diseases and Related Topics affected by disease and diet. A high consumption of muscle meats that contain creatine in the diet may give rise to high serum creatinine. A complete 24-hour urine collection is best, but collecting 24-hour urine samples may be difficult for ambulatory patients. The skeletal muscle mass (in kilograms) is sometimes very roughly estimated with this equation: the 24-hour urinary creatinine (grams per day) is multiplied by 18. Urinary creatinine levels are increased with exercise and with high meat intake (13). Urinary 3-methylhistidine is found only in muscle and is associated with muscle mass. A complete 24-hour urine 3-methylhistidine collection is required to obtain estimates of muscle mass. Calcium Serum calcium levels may be measured using total calcium or ionized calcium tests, but both are tightly controlled and change little in response to diet; hence, they are rarely used for nutritional status assessment. Calcium is primarily transported in the blood either freely or bound with albumin, and it is involved in muscle contraction and blood clotting (13). The regulation of calcium and phosphorus levels in the blood is influenced by vitamin D, calcitonin, and parathyroid hormone (15). Iron There are many types of nutrition-related alterations to red blood cell and hemoglobin synthesis, including iron-deficiency anemia, folate-related anemia, and vitamin B12- deficiency anemia. Other non-nutritional conditions may contribute to microcytic or macrocytic anemias and should be considered when evalu- ating the biomarkers. If anemia of chronic disease is present, increased ferritin levels are not representative of iron-deficient status. For example, individuals with arthritis who are truly iron-deficient may have elevated or normal serum ferritin levels. It is important to evaluate each biochemical test and disease state to determine if iron supplementation is warranted. Hyperglycemia Fasting blood glucose helps to identify abnormal glucose metabolism owing to diabetes or drugs. These tests are particularly important for those with obesity, a family history of heart disease, atherosclerosis, or diabetes. It is important to ensure that individuals fast for 12 hours before the blood draw. Markers of Inammation Many of the acute-phase proteins are used to assess the presence of inflammation. A common medication and nutri- tional interaction is between the anticoagulant, warfarin, and vitamin K, which compete with each other for the same binding site in the coagulation cascade (17). Clinical manifestations occur late and are nonspecific, and may also be related to other conditions or multiple nutrient deficiencies. These signs and symptoms may be caused by a disease, medication, or nutritional deficiency. Comorbidities The presence of other diseases often increases risk for malnutrition. Some diseases have symptoms that may appear similar to those resulting from nutritional deficiencies. Biotin and riboflavin deficiencies include scaly, red rashes on the face and around orifices, which should be not be confused with the facial rash often found on patients with systemic lupus erythematosus. But dietary assessment is difficult and must be done carefully to distinguish under- or malnutrition owing to diet alone (a primary deficiency) from that resulting from other causes (secondary deficiency) (20). Primary deficiency results from inadequate intake, which may be influenced by socioeconomic status and conditions such as alcohol abuse or eating disorders. Secondary nutrient deficiencies result from increased physiological needs, increased nutrient losses in feces and urine, and other causes. In planning interventions it may also be helpful to know about shopping and cooking habits and the frequency of meals consumed away from the home (5). Medications and dietary supplement intakes are important to consider when assessing dietary intake. Some medications provide nutrients, such as antacids containing relatively large amounts of calcium.

Hypokalaemia aggravates ileus, so take care to add supplements to replace the potassium lost in the intestinal secretions. If you do decide to re-open the abdomen, do so very carefully, so as not to make more damage in the bowel and create a situation far worse than before. If you find much sepsis, wash out the abdomen thoroughly and look for a bowel leak. If this is in the proximal jejunum, introduce a feeding tube in the distal part of the bowel.

So, in spite of the limitations of the history, it may be the only way you have Alternatively misoprostol 200g bd up to qid will help of making the diagnosis. The decision to abandon medical for surgical treatment will often depend on the social circumstances; omeprazole, cimetidine and antacids may cost more than the patients salary if symptoms are chronic, so operation may be a reasonable cost-effective alternative. Do not forget that tuberculosis and burns can cause chronic gastric or duodenal ulcers, often leading to fibrosis and stricturing. Look for other signs suggesting other diagnoses: tenderness over the gallbladder (cholecystitis), Fig. B, penetration into the (oesophageal candidiasis), pancreatitis and epigastric liver or pancreas. As it is expensive and easily damaged, instruct a dedicated nurse to look after it, and do not leave it to anyone. It is very frustrating to find that your machine does not work when you need it urgently. Do not keep it in its case which is easily stolen and where the flexible fibres can be damaged. Keep the additional pieces carefully in a box, and the biopsy forceps from being tangled up or caught in doors. You should try to find a room dedicated to endoscopy; this should have two trolleys for patients and one for the Fig. Check the fuse box and (5) local anaesthetic spray, the bulb: if necessary, replace them.

Just as you pass the cardia, blow some air in and turn the scope slightly down and left (as the oesophago-gastric junction is at a slight angle), and blow air into the stomach so you can see its lining. If the view is red (unless the lumen is full of blood), the endoscope tip is against the mucosa, so withdraw it and blow air in. Curve the endoscope over the tongue, which should be kept down inside the mouth, and into the pharynx keeping Fig. Straightening the endoscope by deflecting A, use the middle finger for suction and blowing air. The endoscope then passes effortlessly down the oesophagus as resistance of the cricopharyngeus is lost: you can easily feel this. You rarely will need to go past the 2nd part of the duodenum, and anyway then you will need a side-viewing endoscope. An ulcer shows as a yellowish sloughy area, which may bleed slightly on touching with the endoscope Fig. Practical Gastrointestinal Endoscopy, helicobacter near the pylorus and examine the mucosa of Blackwell 2nd ed 1982 p.
