Few studies have examined medical students' perceptions of community medicine and specialty choice through comparison between students of quotas related to community medicine and regular admission. We conducted a questionnaire survey on students' desire for future work places, types of health facility/hospital, medical specialization, and community medicine involving year 1 to year 5 students in Gifu University School of Medicine (n=335, selective admission: regular admission=81:254) . This study demonstrated that the selected students for community medicine (years 1 to 5) preferred to work at a core/small-sized hospital in a rural area and tended to choose the specialties that were characterized by primary care, such as pediatrics. Moreover, they had positive perceptions of community medicine. Further follow-up study needs to be undertaken in order to explore how students are actually engaging in community medicine after graduation.

CD10, a marker of immature B lymphocytes, is expressed in the developing epithelium of mammary glands, hair follicles, and renal tubules of human fetuses. To assess mesenchymal and stromal expression of CD10, we performed immunohistochemical assays in whole body sections from eight fetuses of gestational ages 15-20 weeks. In addition to expression in urinary tract and intestinal epithelium, CD10 was strongly expressed at both gestational ages in fibrous tissues surrounding the airways from the larynx to lung alveoli, in the periosteum and ossification center, and in the glans of external genitalia. CD10 was not expressed, however, in other cavernous tissues. These findings suggest that mesenchymal, in addition to epithelial cells at specific sites, are likely to express CD10. The glomeruli, alveoli, and glans are all end products of budding or outgrowth processes in the epithelium or skin. However, in contrast to the CD34 marker of stromal stem cells, CD10 was not expressed in vascular progenitor cells and in differentiated vascular endothelium. The alternating pattern of CD10 and CD34 expression suggests that these factors play different roles in cellular differentiation and proliferation of the kidneys, airway and external genitalia.

In serial sagittal sections of a fetus on week 9 (crown-rump length, 36 mm), we incidentally found absence of the usual portal vein through the hepatoduodenal ligament. Instead, an anomalous portal vein originated behind the pancreatic body, crossed the lesser sac and merged with the upper part of the ductus venosus. During the course across the lesser sac, the vein provided a deep notch of the liver caudate lobe (Spiegel's lobe). The hepatoduodenal ligament contained the hepatic artery, the common bile duct and, at the right posterior margin of the ligament, and a branch of the anomalous portal vein which communicated with the usual right branch of the portal vein at the hepatic hilum. The umbilical portion of the portal vein took a usual morphology and received the umbilical vein and gave off the ductus venosus. Although it seemed not to be described yet, the present anomalous portal vein was likely to be a persistent left vitelline vein. The hepatoduodenal ligament was unlikely to include the left vitelline vein in contrast to the usual concept.

The raphe of the human penis and scrotum is considered to develop secondarily after disappearance of the initial midline seam by fusion of the bilateral genital folds. However, the fetal development was still obscure. We examined histological sections of 30 fetuses (17 males and 13 females) at 10-15 weeks. In male fetuses, the scrotum was not yet clearly identified because of no descent of testis. The perineal raphe was thin and wavy at 10 weeks, and it was continuous with and took a direction same as the inferior wall of the closed penile urethra after physiological hypospadias. Depending on growth of the bulbospongiosus muscle and corpus spongiosus penis, the midline intermuscular septum obtained a connection to the subcutaneous wavy raphe and made the latter thick and straight at 12-15 weeks. Notably, the perineal raphe extended posteriorly to attach to the external anal sphincter. In female fetuses, an epithelial fusion occurred along a short distance at the posterior end of the vestibule. However, in front of the external anal sphincter, a large midline mesenchymal tissue from the urorectal septum did not contain a raphe-like structure. Moreover, since the bilateral bulbospongiosus muscles were separated widely by the vestibule, they did not provide a midline septum. Fetal development of the perineal raphe was accelerated by reinforcement from the muscular septum. In contrast, without such a muscular support, the female raphe could not maintain its growth even if the seed appeared at the posterior end of the vestibule.

Background : The effects of rehabilitation on hemodialysis patients are unknown. We assessed the effects and investigated the association between rehabilitation treatment effects and all-cause mortality. Methods : This prospective cohort study included 120 patients on maintenance hemodialysis. ADL was assessed using the Functional Independence Measure (FIM) score (total points, 126), which comprises 13 motor items (total points, 91) and five cognitive items (total points, 35). A survival curve was constructed using the Kaplan-Meier analysis and stratified into an increase or no-increase of the FIM score. Multivariable logistic regression analysis was used to determine factors associated with the effects of rehabilitation. Discriminative sensitivity of FIM cognitive items for an increase in total FIM was estimated using the area under the receiver operating characteristic (AuROC) curve. Results : The average total FIM score increased from 64.2±3.6 to 75.8±3.0, and the increase in FIM motor and cognitive items was 11.0±1.3 and 0.5±0.6, respectively. The cumulative survival rate within 2.5 years was significantly higher in the FIM increase group than that in the FIM no-increase group. FIM cognitive items and anemia were significantly associated with rehabilitation effects, and AuROC showed that a cutoff of 34 points in cognitive FIM had moderate discriminative sensitivity for a total FIM increase (AuC, 0.719 ; p<0.0008). Conclusions : Rehabilitating hemodialysis patients improved their FIM score (particularly the motor items), and a higher FIM score resulted in a better prognosis. The effectiveness of rehabilitation depends on maintaining a perfect FIM cognitive score.

PURPOSE: The purpose of this study is to provide better understanding as to how the "double" vascular arcades, in contrast to other intestinal marginal vessels, develop along the right margin of the pancreatic head. MATERIALS AND METHODS: In human fetuses between 8-30 weeks, we described the topographical anatomy of the vessels, bile duct, duodenum as well as the ventral and dorsal primordia of the pancreatic head with an aid of pancreatic polypeptide immunohisto-chemistry. RESULTS: The contents of the hepatoduodenal ligament crossed the superior side of the pylorus. Moreover, the right hepatic artery originating from the superior mesenteric artery ran along the superior aspect of the pancreatic head. An arterial arcade, corresponding to the posterior pancreaticoduodenal arteries, encircled the superior part of the pancreatic head, whereas another arcade, corresponding to the anterior pancreaticoduodenal arteries, surrounded the inferior part. The dorsal promordium of the pancreas surrounded and/or mixed the ventral primordium at 13-16 weeks. Thus, both arterial arcades were likely to attach to the dorsal primordium. CONCLUSION: The fetal anatomy of the pancreaticoduodenal vascular arcades as well as that of the hepatoduodenal ligament were quite different from adults in topographical relations. Thus, in the stage later than 30 weeks, further rotation of the duodenum along a horizontal axis seemed to be required to move the pylorus posterosuperiorly and to reflect the superior surface of the pancreatic head posteriorly. However, to change the topographical anatomy of the superior and inferior arterial arcades into the final position, re-arrangement of the pancreatic parenchyma might be necessary in the head.

Gastric adenocarcinoma of the fundic gland mucosa type (GA-FGM) was proposed as a new variant of gastric adenocarcinoma of the fundic gland type (GA-FG). However, at present, the influence of Helicobacter pylori and the speed of progression and degree of malignancy in GA-FGM remain unclear. Herein, we report the first case of intramucosal GA-FGM that was endoscopically observed before and after H. pylori eradication over 15 years. The lesion showed the same tumor size with no submucosal invasion and a low MIB-1 labeling index 15 years after its detection using endoscopy. The endoscopic morphology changed from 0-IIa before H. pylori eradication to 0-IIa+IIc and then 0-I after H. pylori eradication. These findings suggest that the unaltered tumor size reflects low-grade malignancy and slow growth, and that the endoscopic morphology is influenced by H. pylori eradication.

A male patient with single ventricle pulmonary stenosis, and persistent left superior vena cava underwent original Blalock-Taussig shunt (BTS) at 2 years of age and suffered from infective endocarditis at 38 years of age. A systemic work-up detected dural arteriovenous fistula and aneurysmal dilatation of the original BTS. Cardiac catheterization and cardiac magnetic resonance imaging revealed an appropriate pulmonary vasculature for bidirectional Glenn anastomosis and sufficient antegrade pulmonary blood flow through the pulmonary valve. Bilateral bidirectional Glenn anastomosis and resection of the aneurysm of the BTS-associated aneurysm were successfully performed.

Annals of Coloproctology 2023;39(2):155-163
Purpose:
The albumin-to-globulin ratio (AGR) is a recognized chronic inflammation marker. No evidence regarding the relationship between AGR level and ulcerative colitis (UC) exists. The aim of this study was to evaluate the association between AGR and clinical outcomes among Japanese subjects with UC.
Methods:
The study subjects consisted of 273 Japanese individuals with UC. AGR was divided into 4 categories (low, moderate, high, and very high). The definition of complete mucosal healing (MH) was based on the Mayo endoscopic subscore of 0. Clinical remission (CR) was defined as no rectal bleeding and no abnormally high stool frequency (<3 times per day).
Results:
The percentage of MH was 26.4%. High AGR and very high AGR were significantly positively correlated with CR (adjusted odds ratio [OR], 5.85; 95% confidence interval [CI], 2.52–14.18 and adjusted OR, 4.97; 95% CI, 2.14–12.04) and complete MH (adjusted OR, 4.03; 95% CI, 1.56–11.51 and adjusted OR, 5.22; 95% CI, 1.97–14.89), respectively after adjustment for confounding factors (P for trend=0.001). Only in the low C-reactive protein (CRP) group (≤0.1 mg/dL), very high AGR was significantly positively correlated with complete MH but not CR (adjusted OR, 4.38; 95% CI, 1.06–21.77; P for trend=0.017). In the high CRP group, no correlation between AGR and complete MH was found.
Conclusion
Among Japanese patients with UC, AGR may be independently positively correlated with complete MH. In particular, among UC patients with low CRP, AGR might be a useful complementary marker for complete MH.

A 2-month-old male infant was transferred to our hospital for suspected cardiomyopathy because he had livedo reticularis and peripheral coldness. An electrocardiogram showed ischemic change and an echocardiogram showed a dilated, poorly functioning left ventricle. Therefore, we performed urgent cardiac catheterization. The coronary artery was not visualized by aortography, but the single coronary artery arising from the pulmonary artery was depicted by pulmonary angiography. Therefore, we performed emergent surgery. The whole coronary arteries traveled directly inferiorly from the left side of the pulmonary trunk. A patent ductus arteriosus (PDA) was closed at the operation. We established cardiopulmonary bypass using two arterial cannulae through both ascending aortas and pulmonary trunk to maintain coronary blood flow. Direct implantation is difficult because the coronary ostium is far from the ascending aorta. Therefore, we chose to perform the Takeuchi procedure using an intrapulmonary artery tunnel. The patient's postoperative course was good, and he was discharged on postoperative day 22. A case of an anomalous origin of a single coronary artery from the pulmonary artery without any other heart disease is extremely rare. Management of cardiopulmonary bypass and myocardial protection in this abnormality is discussed.
