Management of dehydration develop hyponatraemia (serum sodium less than 130 mmol/liter). This is especially common in children with shigellosis and in severely malnourished children with edema. ORS is safe and effective for nearly all children with hyponatraemia, an exception being children with edema for whom ORS provides too much sodium. Management of dehydration The management of dehydration typically involves the use of oral rehydration solution (ORS). Standard home solutions such as salted rice water, salted yogurt drinks, vegetable and chicken soups with salt can be given. Home solutions such as water in which cereal has been cooked, unsalted soup, green coconut water, weak
Serum free light-chain measurement Serum free light-chain measurement Immunoglobulin light chains that are circulating in serum in a free (unbound) state are called free light chains (FLCs). Measurement of the serum level of FLCs became practical as a clinical blood test in recent decades. These tests are used as an aid in the diagnosis and monitoring of multiple myeloma and related disorders. There are two types of immunoglobulin light chain produced in humans, designated by the Greek letters kappa (κ) and lambda (λ). Comparing the ratio of κ FLCs to λ FLCs in a person's serum against reference ranges indicates whether that person may
