Akita has the fastest aging community in Japan. Increasing demand for emergency care and subsequent hospital care for elderly patients is placing excessive pressure on community hospitals because of the chronic shortage of doctors and other medical staff. The characteristic features of these patients are comorbidities, high incidence of cognitive disorders of varying degrees, and physical frailty. To address these urgent problems in a comprehensive manner, the creation of a special department, the ER and GP (general practitioners) department, might be an effective solution. The absence of a GP section in the hospital and lack of family physicians is a major problem in the Japanese medical system. In this context, Akita prefectural government established a training institute for general practitioners and family physicians in Akita Kousei Medical Center in 2012. Only 6 trainees have joined the program in 4 years, so major problems remain. One is the limited human resources available: young doctors and students are still not familiar with the specific area of GP. This is because of the long history of Japanese postgraduate training that is focused on cultivating specialist physicians. The second major problem is the differences that often exist between these doctors─generalists include both hospitalists and family physicians─and these two groups sometimes have completely different mentalities. More time is needed to establish a new style of hospital medicine.
2.Hydrocephalus Associated with Minor Intraventricular Hemorrhage in Patient Undergoing Maintenance Hemodialysis

A 72-year-old woman on dialysis acutely developed disturbed consciousness and severe hypertension. Head computed tomography (CT) demonstrated only ventriculomegaly without bleeding. Her consciousness level further deteriorated after dialysis using heparin, and subsequent head CT revealed a new, minor intraventricular hemorrhage. Hemorrhage-associated hydrocephalus was diagnosed, and the installation of a ventriculoperitoneal shunt resulted in good recovery. The patient might have experienced minor repeated bleeding and developed latent post-hemorrhagic hydrocephalus. Even minor bleeding could cause acute exacerbation of hydrocephalus; therefore, clinicians should be alert to hydrocephalus when a dialysis patient develops disturbed consciousness without any evidence of stroke on head CT.

Since the discovery of the first strain in 1961 in England, MRSA, the most notorious multidrug-resistant hospital pathogen, has spread all over the world. MRSA repeatedly turned down the challenges by number of chemotherapeutics, the fruits of modern organic chemistry. Now, we are in short of effective therapeutic agents against MRSA prevailing among immuno-compromised patients in the hospital. On top of this, we recently became aware of the rise of diverse clones of MRSA, some of which have increased pathogenic potential compared to the classical hospital-associated MRSA, and the others from veterinary sources. They increased rapidly in the community, and started menacing otherwise healthy individuals by causing unexpected acute infection. This review is intended to provide a whole picture of MRSA based on its genetic makeup as a versatile pathogen and our tenacious colonizer.

Background/Aims:
Endoscopic ultrasound (EUS)-guided pancreatic duct drainage is a well-established procedure for managing pancreaticojejunostomy anastomotic strictures (PJAS) post-Whipple surgery. In this study, we examined the effectiveness and safety of EUS-guided pancreaticojejunostomy (EUS-PJS).
Methods:
This retrospective, single-arm study was performed at Aichi Cancer Center Hospital on 10 patients who underwent EUS-guided pancreaticojejunostomy through the afferent jejunal loop using a forward-viewing echoendoscope when endoscopic retrograde pancreatography failed. Our primary endpoint was technical success rate, defined as successful stent insertion. The secondary endpoints were early and late adverse events.
Results:
A total of 10 patients underwent EUS-PJS between February 2019 and October 2023. The technical success rate was 100%. The median procedure time was 23.5 minutes. No remarkable early or late adverse events related to the procedure, except for fever, occurred in two patients. The median follow-up duration was 9.5 months, and the median number of stent exchanges was two. A stent-free state was achieved in three patients.
Conclusions
EUS-PJS for PJAS management after pancreaticoduodenectomy appears to be an effective and safe procedure with the potential advantages of fewer reinterventions and the creation of a permanent drainage fistula.

Background/Aims:
Biliary obstruction drainage in patients with hepatocellular carcinoma (HCC) is associated with symptom palliation, improved access to chemotherapy, and improved survival. Stent placement and exchange via endoscopic retrograde cholangiopancreatography biliary drainage risk traversing the HCC, a hypervascular tumor and causing bleeding. Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) potentially prevents procedure-related bleeding. Therefore, we evaluated the efficacy and safety of EUS-HGS as an alternative treatment for biliary obstruction in patients with HCC.
Methods:
This was a retrospective study of all EUS-HGS procedures performed in patients with HCC at the Aichi Cancer Center Hospital, Japan, from February 2017 to August 2023.
Results:
A total of 14 EUS-HGS procedures (42.9% primary) were attempted in 10 HCC patients (mean age 71.5 years, 80.0% male). Clinical and technical success rates were 92.9% and 90.9%, respectively. The observed procedure details in the 13 successful procedures included B3 puncture (53.8%), 22-G needle (53.8%), fully covered self-expandable metal stent (100%), and mean procedure time (32.7 minutes). There was no bleeding. Mild complications occurred in 27.3%. All patients resumed oral intake within 24 hours.
Conclusions
EUS-HGS is a technically feasible and clinically effective initial or salvage drainage option for the treatment of biliary obstruction in patients with HCC.
