Two years have passed since a patient who started to use the respirator for a tuberculosis sequela and chronic respiratory failure at home. During this period, the patient got several short-term admissions into the hospital. After his first discharge, the patient and his family felt anxiety about recupration at home. It was the first time for us to provide home care services to a respirator wearing patient. However, the shift to recuperation at home was realized as an understanding was reached between physicians who decided upon care home and the patient's wife who wished “to live with the husband together”. The patient is now playing a role as a father and as a husband, and he is leading a full life. In this study, the personal and familial circumstances of the patient, decision-making about home care and community support were analized. We coucluded that there were several important factors for successful recuperation at home:specification of contents of concrete medical support to a patient and a family;an immediate suitable action at the time of change of a patient's condition;taking periodic rests of a patient and a family;and a good family relationship.

A man in his 60s, who was diagnosed as having postoperative recurrent gastric cancer with lymph node and spinal metastases, was admitted to our palliative care unit (PCU). He was unable to receive further aggressive chemotherapy for cancer because of bilateral hydronephrosis and chronic renal failure. He had chronic urethral infection and hence required continuous antibiotic administration. Although his infection was well controlled with antibiotics, his oral intake gradually declined. Seventeen days after admission, he developed systemic hemorrhage, including hematuria and oral bleeding. Coagulation tests revealed that the patient had markedly prolonged prothrombin time (PT) and activated partial thromboplastin time (APTT) but no thrombocytopenia, fibrinogen consumption, or increased fibrin/fibrinogen degradation products (FDP) level. Serum level of protein induced by vitamin K absence or antagonist II (PIVKA-II) was markedly high, and vitamin K level was below the lower limit of the reference range. After he was administered intravenous vitamin K, his symptoms markedly improved. Many patients with advanced cancers tend to have malnutrition, anorexia, and chronic infection that require antibiotic administration. Prophylactic administration of vitamin K might be sometimes necessary for preventing catastrophic hemorrhage.

Corticosteroids are used in the treatment of many diseases; however, they also induce various side effects. Dexamethasone is one of the most potent corticosteroids, and it has been reported to induce the side effect of impaired salivary gland function. This study aimed to evaluate the effects of dexamethasone on mouse submandibular gland function to gain insight into the mechanism of dexamethasone-induced salivary hypofunction. The muscarinic agonist carbachol (CCh) induced salivary secretion and was not affected by short-term dexamethasone treatment but was decreased following long-term dexamethasone administration. The expression levels of the membrane proteins Na-K-2Cl cotransporter, transmembrane member 16A, and aquaporin 5 were comparable between the control and long-term dexamethasone treatment groups. The CCh-induced increase in calcium concentration was significantly lower in the presence of extracellular Ca in the long-term dexamethasone treatment group compared to that in the control group. Furthermore, CCh-induced salivation in the absence of extracellular Ca and Ca ionophore A23187-induced salivation was comparable between the control and long-term dexamethasone treatment groups. Moreover, salivation induced by the Ca-ATPase inhibitor thapsigargin was diminished in the long-term dexamethasone treatment group. In summary, these results demonstrate that short-term dexamethasone treatment did not impair salivary gland function, whereas long-term dexamethasone treatment diminished store-operated Ca entry, resulting in hyposalivation in mouse submandibular glands.
