Clinical Case Reports for the Evidence-Based Era

<p>Warfarin sodium (Latin: Warfarinum natricum), found under the trade name Warfin, is an effective anticoagulant used in the prevention and treatment of thrombosis. It is widely used after cardiac surgery, especially after implantation of an artificial heart valve prosthesis. Warfin's role is to prevent blood from clotting in the prosthesis and valve components and to help dissolve any clots that form.</p><p>Patients must continue anticoagulant treatment for the rest of their lives. They also remain under the constant medical care of the cardiology clinic. In general, they should monitor the prothrombin time (PT), or the time of blood clot formation, every 4-6 weeks to see how the clotting factors that go into the so-called prothrombin syndrome are working. The result is presented under the name International Normalized Ratio (INR) (<i>Enternational</i><i>Normalized Ratio)</i> [1]. In order to maintain stable blood density values, patients should adhere to a well-balanced diet, thus ensuring that the body receives the recommended daily dose of vitamin K contained in foods. Too high a dose of vitamin K in relation to the body's needs can significantly affect the INR value in the blood tested and create difficulties in selecting the antivitamin K dose [2].</p><p></p><p>There are three classified forms of vitamin K: K1 and K2 - derived from a natural source, and K3 which is a synthetic chemical compound. Vitamin K1 (phylloquinone) is synthesized exclusively in plants and taken with food, while K2 is a group of compounds known as menaquinones (MK-n) [3]. These compounds are synthesized by intestinal bacteria. They are mainly found in animal products, including those that are fermentable (Table 1).</p><p>Table 1.</p><p>Recommendations from the FAO (<i>Food and Agriculture Organization of the United Nations</i>) and WHO (<i>World Health Organization</i>). <i>World Health Organization), </i>for sufficient intake of AI (<i>Adequate</i><i>Intake</i>), expressed in μg of phylloquinone/os/d since 2008, have not changed and are 65 μg of phylloquinone/os/d for women ≥ 19 years of age while 55 μg of phylloquinone/os/d for men ≥ 19 years of age [5]. It is now accepted that the therapeutic INR for anticoagulant treatment in patients after artificial valve surgery should be in the range of 2.5 - 3.5 regardless of gender [6, 7]. The clinical efficacy of Warfin depends on the plasma vitamin K concentration, which is influenced by the amount of vitamin K ingested through food and from supplementation. The U.S. government agency FDA (<i>English </i><i>Food and Drug</i><i>Administration)</i> reports that a daily vitamin K intake of 400 μg or more can completely nullify the anticoagulant effects of Warfin taken by the patient [8, 9].</p><p>Selecting the right vitamin K-containing foods and distributing them in meals is a major challenge for the dietitian. Taking into account the patient's general condition and his or her age, gender, weight, comorbidities, other medications and supplements he or she is taking, as well as specific behavioral behaviors (diet, exercise), the dietitian can properly tailor an individual nutrition plan for a specific patient. The more information the nutritionist receives, the more accurate the result of his work will be. Green parts of vegetables and fruits are characterized by a high content of vitamin K1 (phylloquinone), so when establishing a diet plan for a patient, this factor should be taken into account first and foremost.</p><p></p><p>Vitamin K is also involved in bone metabolism. Long-term use of Warfin may disrupt the homeostasis of calcium metabolism in the patient's body, resulting in osteopenia and, consequently, osteoporosis. However, these are remote consequences. Additional factors such as age, gender, physical activity, genetic conditions may contribute to their occurrence [10].</p><p>An important element is the absorption of vitamin K in the body. The absorption of phylloquinone requires the cooperation of bile and pancreatic juice. It is a fat-soluble vitamin, so adding it to a meal results in higher absorption. Vitamin K is absorbed in the small intestine and is stored in the liver. There are differences between the absorption of vitamin K1 and K2. The former is absorbed only 10-15% of the total amount of this vitamin taken in with food, while K2 is absorbed almost completely and has a long biological half-life [10]. In the overall picture, vitamin K modifies coagulation stability, but it should not be excluded from the patient's diet because it is essential for the normal functioning of the human body. In addition to its involvement in the process of blood coagulation, it is involved in the maintenance of proper bone tissue homeostasis and in the proper functioning of the nervous system and brain function.</p><p></p><p>It can be assumed that a properly balanced dietary plan will contribute to the maintenance of normal concentrations of coagulation factors when confronted with anticoagulants and minimize fluctuations in the blood coagulation index.</p>

Non-Hodgkin's lymphomas are a group of diseases caused by neoplastic transformation of lymphoid cells. Anaplastic large cell lymphoma (<i>Anaplastic large cell lymphoma; </i><i>ALCL)</i>ALK+ (<i>anaplastic lymphoma kinase (ALK)-positive ALK+)</i>. is a neoplasm that originates from T lymphocytes. ALK is a tyrosine kinase receptor with an as yet undiscovered ligand so-called "orphan" (<i>orphan receptor</i>). Activation of of abnormal transmission is caused by a translocation involving the 2p23 region. ALK activation is thought to activates the STAT3, AKT/PI3K, RAS/ERK pathways responsible for cell proliferation and the cell cycle. The occurrence of ALCL ALK+ is relatively rare. It occurs in 3% of adult non-Hodgkin's lymphoma patients and in 10-15% of pediatric lymphoma patients. ALCL ALK+ is an aggressive lymphoma. It is mostly found in younger people (median age 34 years). It is more common in men than in women. The disease mainly occupies lymph nodes, but 60% of patients also have extranodal manifestations. The ALCL ALK+ staging classification uses the Ann Arbor classifications are used. Within 5 years of treatment, 60% of patients remain free of disease recurrence. [1]

Defects Congenital defects are abnormalities of the structure of organs created before birth, which lead to dysfunction of these organs. It is estimated that the formation of birth defects birth defects are influenced by: toxic-environmental factors (in 5-10%) and genetic factors (in 20-25%), but in 70-80% no cause can be determined. The incidence of all congenital malformations of congenital malformations in newborns and infants is about 4%, less than 4% of them (about 3.9%) involve the respiratory system. Nearly half of children with congenital defects of the respiratory system die before the age of five. Symptoms of defects in the respiratory system of the respiratory system include chronic or recurrent respiratory infections, symptoms of respiratory failure, coughing, and hemoptysis. Sometimes a defect in the respiratory system of the respiratory system is asymptomatic and detected accidentally.

Jest to rzadki przypadek, w którym pierwotnie zdiagnozowane przerzuty FTC do kości śródstopia nie zostały potwierdzone w dalszej diagnostyce. W związku z tym wykonano jedynie resekcję guza. Diagnostyka pooperacyjna opierała się na wielokrotnych, dokładnych badaniach histopatologicznych wycinków pobranych w trakcie operacji, co wykluczyło niekorzystne rozpoznanie. Dzięki temu uniknięto amputacji stopy.
