A 9-year-old boy with multisaccular thoracic aortic aneurysm associated with coarctation of the aorta underwent definitive repair under partial cardiopulmonary bypass. The operation consisted of resection of the aneurysm and reconstruction of the descending aorta. Aortic reconstruction was done without an artificial graft, and extended end-to-end anastomosis was performed successfully. He has been doing well and there was no significant restenosis at the repair site 5 years after the operation. Some authors reported that untreated coarctation of the aorta frequently developed aneerysm, which usually has multisaccular lesions. Surgical strategy of aortic reconstruction for coarctation of the aorta in boyhood should be decided prudently to avoid postoperative complications.

Objective: The care of patients with Alzheimer’s disease (AD) has a significant impact on the life of caregivers. Some of the major daily tasks for caregivers are the administering and management of patients’ medications. The aims of the present study were to evaluate the current state of administering and management of medications by caregivers, and the usefulness of medicated patches for improving compliance.
Methods: We sent questionnaires to 62 caregivers of AD patients, and 60 responses were analyzed (response rate: 96.8%).
Results: We found that approximately half of caregivers had some difficulties with administering and managing medications. A total of 80% of caregivers took less than 3 min to administer and manage medications. Approximately half of caregivers responded that patches were useful, but 15% stated that current medications were not the cause of difficulties. These respondents were concerned that patches may result in adverse skin reactions.
Conclusions: The results of this survey indicate that caregivers do not have difficulties with administering and managing medications, and further concern is needed about the usefulness of medicated patches.

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.

To investigate whether magnesium abnormalities are associated with the administration of magnesium-containing laxatives in a palliative care setting, we measured the serum magnesium levels in 48 patients with advanced cancer at our palliative care unit (PCU). The mean magnesium concentration in all patients was 2.09 mg/dl (confidence interval [CI], 1.38-3.62). Patients receiving magnesium-containing laxatives (n=38) showed significantly higher serum magnesium concentrations than patients without laxatives (n=10) (2.17 mg/dl vs 1.8 mg/dl, p=0.006). Although 10 patients had serum magnesium abnormalities (hypomagnesemia, 8 and hypermagnesemia, 2), we did not observe clinical manifestation associated with magnesium abnormalities. Interestingly, neither the duration nor the dose of laxatives correlated with serum magnesium concentration. Overall, patients at the PCU tend to have magnesium abnormalities and their symptoms may be analogous to those of advanced cancer patients; in particular, terminal patients with such symptoms might be considered to have magnesium abnormalities.

A 72-year-old man suffering from postinfarction angina and atrial septal defect (ASD) underwent a combined operation of four bypass graftings and direct closure of ASD. The great saphenous vein was harvested with the use of a bipolar Nd-YAG laser dissector without scissors or threads. Nd-YAG laser (wavelength: 1.064um) was irradiated to the branches of the saphenous vein through the ceramic tips of the dissector. After about five minutes exposure, the branch was dissected and bleeding from the dissected edge was not seen. Postoperative angiogram six months after grafting showed all grafts were patent, and morphological abnormalities such as reginoal shrinkage, diffuse narrowing and aneurysmal dilation were not observed. We conclude that laser graft harvesting using the bipolar dissector is safe and effective in saving time.

Since arteriosclerosis is a general progressive disease, an aneurysm of the thoracic aorta is not infrequently complicated by ischemic heart disease. Therefore, assessment of indications of surgical treatment and selection of the surgical procedure and auxiliary procedures on the basis of accurate preoperative evaluation of ischemic heart disease are considered to be very important for improving the results of operations for thoracic aortic aneurysm. Recently. we successfully operated on a 64-year-old patient with a left ventricular aneurysm and a descending aortic aneurysm. One-stage operation was performed by a left thoracotomy approach and partial left heart bypass by draining the pulmonary artery into the femoral artery with mild hypothermia. The approach and the auxiliary procedures employed in this patient are considered to be a useful combination applicable also to one-stage operation for descending aortic aneurysm and coronary artery bypass grafting.

A 60-year-old woman underwent surgical treatment of postinfarction ventricular septal perforation (VSP) in the early phase after receiving total cardiopulmonary bypass without aortic occlusion. VSP developed four days after anterior myocardial infarction. On admission, inraaortic balloon pumping was used to obtain hemodynamic stabilization. On the day of admission, emergency total cardiopulmonary bypass was performed. VSP was closed with a Dacron felt patch positioned on the left side of the septum. The anterior wall of the left ventricle was closed with Dacron felt strips and reinforced using a Gore-Tex sheet. Postoperative hemodynamics improved significantly. Although the operation while the heart was beating was difficult technically, the total cardiopulmonary bypass time of this method was not longer than that of operations under cardioplegic arrest. Further more, the area of infarction was easily distinguished by color and bleeding. The surgery during normothermic heart beat was effective in preventing further ischemia of the myocardium. The surgical treatment of VSP in the early phase during normothermic heart beat under total cardiopulmonary bypass was considered to be more effective and safer than operations under cardioplegic arrest.

Several prospective studies on laparoscopy-assisted distal gastrectomy for early gastric cancer have been initiated, but no prospective study evaluating laparoscopy-assisted total gastrectomy or laparoscopy-assisted proximal gastrectomy has been completed to date. A non-randomized confirmatory trial was commenced in April 2015 to evaluate the safety of laparoscopy-assisted total gastrectomy and laparoscopy-assisted proximal gastrectomy for clinical stage I gastric cancer. A total of 245 patients will be accrued from 42 Japanese institutions over 3 years. The primary endpoint is the proportion of patients with anastomotic leakage. The secondary endpoints are overall survival, relapse-free survival, proportion of patients with completed laparoscopy-assisted total gastrectomy or laparoscopy-assisted proximal gastrectomy, proportion of patients with conversion to open surgery, adverse events, and short-term clinical outcomes. The UMIN Clinical Trials Registry number is UMIN000017155.
