A 38-year-old man was admitted to our hospital with fever and skin rash, and he was diagnosed as having dermatomyositis. He was treated with anti-inflammatory steroid and immunosuppressive agents. On hospital day 48, chest computed tomography (CT) revealed a nodule measuring approximately 2 cm in size in the lower lobe of the right lung (S9). Bacterial and/or fungal infection was suspected, but there was no response to antibiotic or antifungal treatment. A week later, repeat chest CT revealed the tumor now measuring approximately 6 cm in size in the lower lobe of the right lung. We performed bronchoscopy, and bacteriological examination of the transbronchial biopsy specimen revealed pulmonary tuberculosis. Interferongamma release assay (IGRA) before the initiation of immunosuppressive treatment was negative, so we did not administer treatment for latent tuberculosis infection. He was, however, treated with isoniazid, rifampicin, ethambutol, and pyrazinamide for 9 months, following which radiological features improved gradually. Here we describe in detail this rare case of a negative IGRA result before immunosuppressive therapy in a relatively young Japanese man who went on to develop active tuberculosis with a rapidly-growing pulmonary lesion during hospitalization.

A 68-year-old man was admitted to our hospital with complaints of fatigue, polyuria, and loss of appetite, and was diagnosed with diabetic ketosis. Chest and abdominal computed tomography (CT) showed a pulmonary tumor on the right S3 and multiple liver tumors. Blood chemistry revealed elevated levels of amylase and hepatobiliary enzymes. Pathological examination of a biopsy specimen from the liver tumor showed a small cell carcinoma. Based on the imaging and pathological findings, we made a diagnosis of extensive disease small-cell lung cancer (ED-SCLC), cT1aN3M1b (HEP, ADR). Treatment with carboplatin and etoposide evoked partial response and the serum level of amylase decreased. Immunohistochemical staining of liver biopsy specimen was positive for amylase, leading to a diagnosis of SCLC with amylase production. About 22 months after the diagnosis of SCLC, he was admitted to our hospital with fatigue, muscular weakness, edema, and hyperpigmentation. Laboratory findings showed elevated serum levels of hepatobiliary enzymes, adrenocorticotropic hormone (ACTH), and cortisol, and a decreased serum potassium level. Urinary potassium level was elevated. Pituitary magnetic resonance imaging showed a normal morphology. We made a diagnosis of SCLC complicated by Cushing’s syndrome. We report this rare case of SCLC with amylase and ACTH production, which was detected in the course of treatment of SCLC.

In patients with epidermal growth factor receptor (EGFR) mutation-positive lung cancer (LC) who have acquired resistance to first and/or second-generation EGFR-tyrosine kinase inhibitors (EGFR-TKIs), detection of EGFR T790M (T790M) mutation is essential before administration of osimertinib. Tissue sample is the main specimen used to detect the T790M mutation, and so cell block preparation using pleural or pericardial fluid should be considered. The utility of body cavity effusion cell block methods in T790M mutation detection have not yet been fully evaluated. This study aimed to evaluate the clinical background and treatment course of LC patients harboring the T790M mutation by using body cavity effusion cell block methods at our hospital. All patients were treated with first and/or second-generation EGFR-TKIs and had developed malignant pleural or pericardial fluid as a result of progressive disease. T790M mutation status was evaluated using body cavity effusion cell block method in 9 patients, from April 2016 to August 2017. We retrospectively evaluated the clinical characteristics and treatment course of these 9 patients (3 males and 6 females; median age 76 years). At the first diagnosis of LC, 7 patients had stage IV cancer; 4 patients were diagnosed by bronchial fibroscopy and 3 were diagnosed from pleural fluid examination. Regarding EGFR mutation, 3 and 6 patients carried the exon 19 deletion and L858R mutation, respectively. Median time interval between the first diagnosis of LC and T790M mutation evaluation was 30.8 months; 7 patients were diagnosed with positive T790M mutation by using body cavity effusion cell block methods. The T790M mutation was highly detected by examination of body cavity effusion cell blocks. Further evaluation is necessary with respect to variations in T790M detection rate based on the specimen collection site and/or progressive disease pattern in different patients.

　　A 56-year-old woman was referred to our hospital because of an abnormal finding in the right pulmonary hilum on chest X-ray. Enhanced chest computed tomography showed hyperplastic bronchial arteries dilating and winding around the trachea and bronchi. A racemose hemangioma of the bronchial artery with multiple bronchial artery aneurysms (diameter <20mm) was seen displacing the trachea and both main bronchi. Bronchoscopy showed submucosal tumor-like lesions at the distal trachea and in both main bronchi, and a dusky-red elevated pulsatile lesion at the orifice of the left B3b＋c. We performed coil embolization of the bronchial artery aneurysm to prevent abrupt rupture of the bronchial aneurysm.

An 81-year-old man was referred to our hospital with bilateral multiple patchy opacities on chest radiography. His chief complaints were a few months’ history of intermittent mild cough and slightly yellow sputum. Chest computed tomography (CT) showed non-segmental air-space consolidations with ground-glass opacities. Amyloid deposition with organizing pneumonia (OP) was seen in transbronchial lung biopsy (TBLB) specimens from the left S8. Three months later, the infiltration originally seen in the left lower lobe was remarkably diminished, and new infiltrations in the lingual and right lower lobes were detected on chest CT. Amyloid deposition with OP was seen in TBLB specimens from the left S4. Transthyretin was detected following immunohistochemical examination. The presence of wild-type transthyretin (ATTRwt) was proven using genetic analysis. The present report describes a rare case of ATTRwt amyloidosis associated with OP.

Objective: The subjects of this study were consumers with cold-like symptoms who visited drugstores to purchase OTC drugs.  The purpose was to elucidate the factors that influence the intention of these consumers to consult pharmacists or sellers.
Design: Analytic observational study
Method: We conducted a survey of consumers who visited pharmacies or drugstores for cold-like symptoms.  Pharmacists and registered sellers (hereafter “pharmacists or sellers”) utilized tools to serve them, entering details in customer records.  We handed postcards to these consumers asking them to respond to questions about the prognosis and the degree of satisfaction about the service they had received.  We then used the customer records and follow-up results to perform linear regression analysis with “I would like to consult the pharmacist or seller again” (hereafter “desire for consultation”) as the dependent variable, and the usefulness of the advice and degree of satisfaction about the explanation and service as the independent variables.
Results: We analyzed the data of 81 consumers for whom we were able to match the customer records and postcards.  The linear regression analysis indicated that “the usefulness of the advice (coefficient of standardization: 0.73)” affected the desire for consultation most, followed by “the degree of satisfaction about the service (coefficient of standardization: 0.24).
Conclusion: We verified that, in self-medication assistance, advice that lets consumers feel the consultation was actually “helpful” by focusing on individual needs, and good customer service were necessary to increase the desire for consultation with pharmacists or sellers, and to encourage actual consultation.

Objectives: The objectives of this study are to evaluate the current situation of concomitant drug use by community-dwelling elderly dementia patients, and to extract factors influencing the presence of potentially inappropriate medications (PIMs).
Method: The research subjects were patients 65 years of age or older for whom concomitant drugs were prescribed on the same prescription form as donepezil hydrochloride.  One hundred and twenty community pharmacies randomly selected from 28 of the 47 prefectures throughout Japan.  Main research topics were sex, age, the clinical department to which the prescribing physician belonged, daily dosage of donepezil, and concomitant drugs.  Concomitant drugs were evaluated using the Beers Criteria: the Japanese Version. Furthermore, to search factors influencing the presence of PIMs, logistic regression analysis was used.
Results: Data for 335 patients were extracted.  The average number of concomitant drug cases per patient were 4.2 (SD 2.6), and 109 patients (32.5%) were prescribed PIMs.  A logistic regression analysis confirmed that significant factors influencing the presence of PIMs were “the clinical department to which the prescribing physician belonged” (OR 4.80, 95%CI 1.01-22.72), “concomitant drug cases” (OR 1.26, 95%CI 1.13-1.41) and “the presence of concomitant use of central nervous system agents” (OR 5.82, 95%CI 3.35-10.11).
Conclusion: This study revealed that more than a few cases of community-dwelling elderly patients of dementia were using concomitant drugs with potential risks.  It suggested that influencing factors were “the specialty of the prescribing physician” and “the presence of concomitant use of central nervous system agents.”

Background: The technique of pancreatoduodenectomy (PD) has evolved, and artery first’ approach was considered for the intraoperative early determination of resectability for borderline resectable cases before the ‘point of no return’ and avoidance of blood congestion resulted in the reduction of blood loss. Also, active application of energy device was useful for the reduced operative time and blood loss. Recently, 3D simulation for hepatobiliary pancreatic surgery has been useful and mandatory. In this presentation, we introduced our recent refinements and advances for PD. ‘Artery first’ approach and vessel sealing system for PD: ‘Artery first’ approach were considered as six different methods as follows; 1) Superior approach, 2) Anterior approach, 3) Posterior approach, 4) Left posterior approach, 5) Right/ medial uncinate approach and 6) Mesenteric approach. A while ago, we preferably applied the mesenteric approach to PD, and also the combination of this approach with vessel sealing system (VSS) significantly reduced intraoperative blood loss (Mesenteric approach with VSS, n=21 vs. non-‘Artery first’ approach without VSS, n=78; 320±174ml vs. 486±263ml, p<0.01). Modified de-rotation method as complete ‘Artery first’ approach: Most recently, for further refinement of operative procedure, we refined a right/medial uncinate and posterior approach as modified de-rotation method. Point of view in this method was the complete clockwise rotation of small intestinal mesentery including ascending colon, in order to linearize from duodenum to jejunum and look at the direct front of superior mesenteric artery (SMA), vein (SMV) and some branched jejunal vessels originated from SMA and SMV (Fig.). Thereby, in the posterior view, the easy dissection of all pancreatic branch originated from SMA can be done. This modified de-rotation method was possible to achieve the complete ‘Artery first’ approach. Preoperative 3D simulation of arterial and venous anatomy: Until now, we applied 3D volumetery software (SYNAPSE VINCENT®) as preoperative simulation for hepatic resection. And recently, for evaluation of the position relationship between arteries and veins surround pancreas head, we adopted this software before PD. As first step, arteries and veins are automatically identified, and small vessels are manually traced on the axial CT view. After that, 3D arterial and venous simulations are combined. Grasp of detailed vessel anatomy and its relationship using preoperative 3D simulation enable to safely perform PD, even in young surgeons (operative time; young 512±49 vs. senior 445±41 min, p<0.01), (blood loss; young 353±203 vs. senior 246±109 ml, p=0.16). Conclusion: Those refinements and advances are possible to safely and easily perform pancreatoduodenectomy.

Background: The glissonean pedicle approach was introduced by Couinaud and Takasaki in the early 1980s. The key of the glissonean pedicle approach is clamping the pedicle first, secondly confirming the territory, and finally dissecting the liver parenchyma. In this presentation, we introduced our recent refinements of glissonean pedicle approach for liver resection. “Approach to the glissonean pedicles at the hepatic hilus” Couinaud described three approaches to the hepatic hilus. 1) Intra-fascial access (Control method): The conventional dissection at the hilus or within the sheath is referred to as intrafascial access However, dissection performed under the hilar plate is dangerous and surgeons have to consider any variations of the hepatic artery and bile ducts. 2) Extra-fascial access (Glissonean pedicle approach): The glissonean pedicle is dissected from the liver parenchyma at the hepatic hilus before dissecting the liver parenchyma. This procedure prevents intrahepatic metastasis of HCC, which spreads along the portal vein and improves the overall survival after surgery. 3) Extra-fascial and transfissural access: If the main portal fissure or the left suprahepatic fissure is opened after dissecting the liver parenchyma, the surgeon can confirm the pedicles that arise from the hilar plate or the umbilical plate. “Operative techniques” 1) Preoperative 3D simulation of the precise anatomy of portal vein, hepatic artery and bile duct at hepatic hilus should be performed. 2) Right glissonean pedicle: The hilar plate is detached from the quadrate lobe. The assistant pulls the liver parenchyma cranially and the operator conversely pulls the hepatoduodenal ligament caudally. Mayo scissors are inserted along the liver parenchyma between the liver parenchyma and glissonean capsule (Fig.1). Then forceps are inserted in the same way and the right main pedicle is taped (Fig.2). The right anterior and posterior glissonean pedicles are taped as well. 3) Left glissonean pedicle: The hilar plate is detached from the liver parenchyma. Then, the Arantius duct is confirmed and the left pedicle is dissected along the left pedicle at the ventral side of the Arantius duct. “Pitfall of glissonean pedicle approach” The right pedicle should be dissected in the liver side as much as possible to prevent the injury of left hepatic duct. If possible, the right pedicle is recommended to be dissected at the level of the second branches separately (Fig.3). The right posterior hepatic duct sometimes branches from the left hepatic duct and the Arantius duct is confirmed and the left pedicle should be dissected along the left pedicle at the ventral side of the Arantius duct because the right posterior hepatic duct branches from the left hepatic duct at the dorsal side of Arantius’ duct. In addition, the intraoperative cholangiogram should be used in the case with the abnormal anatomy of bile duct. Conclusions: Any anatomical hepatectomy can be performed using “glissonean pedicle approach” which allows simple, safe and easy liver resection.
