We report a case of spindle cell type medullary carcinoma of the thyroid in a 77-year-old man. Fine needle aspiration cytology showed numerous spindle cells without inflammation and hemorrhage. The spindle cells were uniform and exhibited no malignant features. Immunocytochemistry was positive for carcinoembryonic antigen and calcitonin, and the tumor was diagnosed as spindle cell type medullary carcinoma. There are various histological subtypes of medullary carcinoma, and diagnosis by cytomorphology alone is difficult. Preservation with LBC fixative was helpful for diagnosis by immunocytochemistry in this case.

Medical students in Japan often want to do clinical rotations abroad. Preparation for these important clinical experiences is essential to maximize the learning opportunities. Language ability is only one small part of assuring success.1) It is important to consider the hospital where the rotation will take place, the specific rotation, the living arrangements and commuting to the hospital. Preparation before the rotation should include practice in performing and writing a complete patient history and physical examination.2) It is very helpful to have a cell phone while abroad, as well as a credit card. Students must bring a white coat, and it is recommended that they also bring a Japanese textbook in the field they will study.3) While on a clinical rotation, students must be active participants in patient care and in discussions. They must be aggressive about answering questions during ward rounds. Students must be aware of many cultural differences to have good relationships with patients and colleagues.

We report the results of aortic arch replacement in 32 patients (20 males, 12 females) with aortic arch aneurysm, including 9 emergency cases. The etiology of aneurysm was atherosclerotic aneurysm in 18 patients, pseudoaneurysm in 1 patient, and aortic dissection in 13 patients. Selective cerebral perfusion (SCP) and retrograde cerebral perfusion (RCP), which are used for brain protection during aortic arch reconstruction, were both employed in this study according to our institutional policy. RCP was started at the moment of circulatory arrest after which the aneurysm was opened. In the case of 1-branch reconstruction or hemiarch replacement, we only employed RCP. If 2-branch reconstruction or total arch replacement was needed, we switched to SCP. After the distal graft anastomosis was performed, antegrade systemic perfusion was started via the 4th branch of the graft. Subsequently, 3 arch vessels was reconstructed with rewarming to shorten the SCP time, and finally proximal graft anastomosis was performed. Distal graft anastomosis with a new technique was applied in the 10 most recent cases. The “cuff” was made at the distal anastomosis site of the graft beforehand and this “cuff” was sutured to the aortic wall in an elephant-trunk fashion. This technique was a simple approach to repairing the distal lesion and allowed easy addition of stitches in case's of bleeding. The in-hospital mortality rate was 6.3% (2 of 32 patients) and the rate of cerebrovascular accident was 6.3% (2 of 32 patients). This technique for aortic arch repair is a useful method that results in low rates of in-hospital mortality and morbidity.

PA-LA communication is a rare congenital heart disease consisting of direct communication between a branch of the PA and LA through an aneurysmal structure. This disease reveals the central cyanosis with clubbed fingers and surgical repair is needed when symptoms are apparent. Computed tomography is highly recommended for definitive diagnosis. Angiographic catheterization is also recommended to support the diagnosis and decide on the treatment. PA-LA communication is categorized into 4 types. Two types do not need cardiopulmonary bypass (CPB) when treated surgically, but the others need CPB. A 16-year-old girl with clubbed fingers was found to have PA-LA communication by 3DCT. She underwent surgery and was discharged in good condition. The surgical procedure was done through median sternotomy without CPB. The anomalous aneurysmal fistula was doubly ligated. No communication was found after ligation by TEE.

The number of surgical treatments for acute aortic dissection in octogenarians is increasing. They should return to their daily life as soon as possible after the operation without any complications. Some literature reported that minimally invasive cardiac surgery (MICS) helps quick recovery for the patients. We report a case of minimally invasive ascending aorta replacement for Stanford type A chronic thrombosed aortic dissection in an octogenarian to help quick recovery. An 81-year-old man was admitted in our hospital suffering from chest and back pain. Enhanced CT scan showed Stanford type A acute thrombosed aortic dissection. The diameter of ascending aorta was 45 mm and the diameter of false lumen was 7 mm. Therefore we decided on medical treatment for this patient according to the guideline. After four weeks medical treatment, ascending aorta was dilated to 49 mm and the false lumen also expanded to 9 mm. He underwent minimally invasive ascending aorta replacement to help quick recovery considering his age. He was discharged 11 days postoperatively without any complications. MICS offers a better cosmetic result, less blood loss, less pain, better respiratory function and quick recovery. Thus, minimally invasive operation for the elderly is also very satisfactory.

Objective: The hospital is changing its formulary reference from paper-based to intranet.  There was concern that both paper-based and intranet versions of the formulary would be necessary.  Revising the paper-based hospital formulary each time package inserts are revised is difficult.  For your review we report on the creation of the iPhone® electronic formulary which enables rapid off-line formulary retrieval and easy updates while at the same time providing low cost service in a light device.
Methods: The CSV (Comma Separated Value) of the hospital formulary dictionary was made using a standard personal computer.  The CSV data file was converted using JAMES2DIC into a HTML file format.  Next, the converted HTML file is transformed into the EPWING (Electronic Publishing WING) format using EBStudio.  Finally, we forward the EPWING dictionary file from the personal computer to the iPhone®.  The retrieval becomes possible by using EBPocket for iOS of EPWING/electronic book viewer software for the iPhone®.  The number of items was assumed to be 29 items thought for a lot of inquiries to exist.
Results: We compared the paper-based formulary with the iPhone® electronic formulary.  As a result, the iPhone4® electronic formulary shortened the retrieval time, was smaller, lighter, and excellent at a lower price.
Conclusion: The iPhone4® electronic formulary enables the user to perform complex full-text searches and retrieve information at a much higher speed than is possible with paper based formularies.  It has the additional advantage of seamless integration and deployment of formulary additions or reference material revisions.  We believe we have successfully created a practical electronic formulary.

We performed a retrospective study of the effects of steroids and the factors that deteriorate renal function in 30 patients with primary focal segmental glomerular sclerosis. The mean observation periods from the onset of proteinuria and from the histological diagnosis by renal biopsy were 6.1 ± 5.0 years and 3.9 ± 3.01 respectively. 87% of the patients had been recerving steroid therapy with or without other drugs. In this study, the patients were divided into 3 groups by the initial dose of steroids. A multivariate analysis was performed on the laboratory findings of the 3 groups. In a short-term observation, there were no significant defferences among the groups. However, in a long-term observation (more than one year) it was clarified that the patients who had been given high doses of steroids tend to maintain their renal functoin. We also found that the patients responding to steroids showed a significantly better prognosis than steroid-resistant patients upon examination their nephrotic status and renal functoin.
This statistical analysis confirmed that the factors deteriorating the renal function are hypertension and hyperlipidemia.
In addition, it was revealed that hyperuricemia, is responsible for the renal dissease, failure?

A 62-year-old woman with idiopathic thrombocytopenic purpura (ITP) was admitted to undergo cardiac surgery for aortic stenosis, angina pectoris, and paroxysmal atrial fibrillation. A bleeding tendency was expected due to the dramatic decrease in platelets during cardiopulmonary bypass. We performed high-dose transvenous gammaglobulin infusion (400mg/kg/day) for 5 consecutive days immediately before surgery. The gammaglobulin therapy caused steady increase of thrombocytes from 4 days after surgery, even though the platelet count showed no significant change preoperatively. The postoperative course was satisfactory with neither a bleeding tendency nor wound infection. High-dose transvenous gammaglobulin therapy is thus useful for perioperative patients with accompanying ITP, who are often under medication with steroids. This therapy is also effective for prevention of infection.

In the presence of Leriche syndrome, the lower extremities are perfused by collateral flow from internal mammary arteries. If an internal mammary artery graft is used in coronary artery surgery, an acute ischemic limb will develop postoperatively. A 52-year-old man was admitted to our department with bilateral claudication. Multidetector row computed tomography with contrast showed total occlusion of the infrarenal abdominal aorta and rich collateral flow to the lower extremities from internal mammary arteries. Cardiac angiography revealed three-vessel disease. Simultaneous coronary artery bypass grafting and an ascending aorto-bifemoral bypass were performed without cardiopulmonary bypass. Postoperative computed tomography angiography showed that grafts to the coronary and bifemoral arteries were patent. This combined procedure is useful for patients with coronary artery disease and aortoiliac occlusive disease. This procedure without cardiopulmonary bypass has not previously been reported.
