Cases

Patient U, aged 57, had surgery - cholecystectomy, choledocholithotomy, drainage of the common bile duct by T-shaped Ker drainage for acute cholecystitis, multiple choledocholithiasis, cholangitis, obstructive jaundice. From the protocol of the operation it is known that one of the concrements was infringed the large papilla of the duodenum and was dropped into the duodenum by pushing. A year after the operation, the patient noted the appearance of continuous pain in the right hypochondrium, jaundice, darkening of the urine. The ERCP revealed dilatation of the extra- and intrahepatic bile ducts (a picture) showing a significant narrowing of the terminal ducts of choledochus (symptom Feather pen).

Parathyroid hormone

Parathyroid hormone (parathyroid hormone)  is one of the main regulators of calcium in the blood. This hormone is very useful information for: parathyroid disease (primary hyperparathyroidism, secondary hyperparathyroidism, autoimmune hypoparathyroidism), osteoporosis, calcium content disorders (hypercalcaemia, hypocalcaemia). Parathyroid  hormone is a protein that is synthesized in the parathyroid glands. It main function is to regulate calcium metabolism in the body.  When the level of calcium in the blood falls, the parathyroid hormone increases to raise the calcium concentration in the blood by sending signals to the bone to: 1. inhibit collagen synthesis in active osteoblasts;  2. activate osteolysis by osteocytes;  3. increase osteolysis by the osteoclasts; 4. increase in the rate of maturation of progenitor cells, differentiating into osteoblasts and osteoclasts. As a result, the calcium level in the blood rises.  However, one of...

Biochem & Blood analyses

A general blood test  involves a study that allows you to identify the number of  leukocytes , red blood cells , platelets and haematocrit  . In addition, the analysis allows to determine  haemoglobin  and erythrocyte indices (MCV, MCH, MCHC, RDV).  The general analysis of blood is carried out, first of all, for an estimation of the general system of a hemopoiesis, inflammatory processes, the maintenance of a haemoglobin and diagnostics of anaemias. A clinical blood test  ,  part of which is a general blood test, is the most commonly used method in clinical laboratory diagnostics. Specialists distinguish three basic components of the clinical blood test, namely: general analysis, leukocyte formula and calculation of ESR. All these studies make it possible to determine parameters such as erythrocyte sedimentation rate (ESR), haemoglobin content, white blood cell count, colour index, count th...
