Primary sclerosing cholangitis (PSC) is commonly associated with ulcerative colitis (UC). PSC progresses independently of UC ultimately resulting in liver failure. There is no established medical treatment to improve the natural course of PSC. Normalization of serum alkaline phosphatase (ALP) in early stage might delay the progress of PSC. A 20-year-old female, had a sudden attack of right hypochondralgia with high fever and abnormal liver function tests without elevation of bilirubin: ALP 478 IU/L, aspartate aminotransferase 360 IU/L, alanine aminotransferase 174 IU/L. Abnormal liver function tests returned to normal after the attacks. Morphological examinations initially indicated then confirmed a diagnosis of PSC. One month after displaying PSC symptoms administration of ursodeoxycholic acid was initiated. Similar attacks of cholangitis were repeated several times over the following two years. Even in the absence of these attacks, she always suffered postprandial hypochondralgia. There was no acute cholangitis in the year prior to the last hospitalization due to abdominal pain and bloody diarrhea. Findings were consistent with UC in the form of entire colitis. Sulfasalazine, metronidazole and semi-vegetarian diet (SVD) were initiated. Metronidazole is routinely used in inflammatory bowel disease (IBD) in our practice with the expectation of elimination of any potentially pathogenic bacteria. SVD was designed for IBD hoping to increase beneficial bacteria. A remission of UC was ascertained during hospitalization. Elevated ALP, in the absence of clinical cholangitis, was decreased to normal after the therapy for UC.

Appendiceal orifice inflammation (AOI) is observed as skip lesion in distal ulcerative colitis (UC). The endoscopic frequency of AOI is reported to be 7.9% to 76% of distal colitis. UC is a relapsing and remitting disease and a morphological change of the large bowel occurs over time. Patient and physician can easily understand the shape of the whole large bowel not through endoscopic photograph but by roentgenogram of the bowel. Therefore, the authors undertake barium enema study when a diagnosis of UC is made. We have experienced a patient with proctitis in which an appendiceal submucosal tumor (SMT) was suspected on the roentgenogram but it was turned out to be a protruding lesion of AOI. A 16-year-old boy visited us with complaining of blood in his stool for the past 10 days. Sigmoidoscopy revealed mild diffuse inflammation. Crypt abscess was found in biopsy specimen. A diagnosis of UC, proctitis type, was made. A double contrast barium enema study revealed a defect shadow with a smooth surface, length 37 mm, height 12 mm, over the appendix. An appendiceal SMT was suspected. Abdominal ultrasonography and computed tomography were non-contributory. Colonoscopy revealed a spiral inflamed mucosa at the site of an appendiceal orifice. There was an inflammation in the cecum surrounding the orifice. Biopsy specimen of the appendiceal orifice showed inflammatory cells infiltration, goblet cell depletion, and cryptitis. The suspected SMT lesion was concluded to be AOI.

Background: The coronavirus disease (COVID-19) pandemic has impacted perinatal women’s mental health. However, protective factors associated with depression among pregnant Japanese women during the pandemic have not been reported. Purpose: The present study investigated the risk and protective factors associated with depression and anxiety among pregnant women during the COVID-19 pandemic. Methods: An online questionnaire was administered to 157 pregnant women between October 2022 and May 2023 at two general hospitals in Japan. The Japanese versions of the Patient Health Questionnaire-9 (PHQ-9) and General Anxiety Disorder-7 (GAD-7) were used to assess symptoms of depression and anxiety. The χ2 test or Fisher’s exact test and multivariate logistic regression model were used to examine factors associated with depression and anxiety among pregnant women. Results: Overall, 47.1% and 35.7% of the pregnant women reported depressive and anxiety symptoms, respectively. A “history of mental illness” was a risk factor for depression and anxiety among pregnant women during the COVID-19 pandemic. Additionally, unmarried status was a risk factor for anxiety among pregnant women, whereas outdoor and indoor exercises were protective factors against depression and anxiety, respectively. Conclusions: Exercise may have protected pregnant women from depression and anxiety during the COVID-19 pandemic. Encouraging exercise may help maintain the mental health of pregnant women who do not have exercise restrictions.

Aim: To detect risk and preventive factors associated with the Omicron variant infection in university students, a combination of a web-based survey and multivariate logistic regression analysis was introduced as the front-line initiatives by the school health practitioners. Design: Questionnaire survey. Methods: The school-wide web-based questionnaire survey was conducted among our university students as a part of the annual health check-up in April, 2023. The positive outcome was confined to the first symptomatic COVID-19 onset during the Omicron variant outbreak. Results: In this self-administered survey, risk or protective associations were merely estimated statistically in university students (n = 5406). In measured factors, karaoke and club/group activities could maintain the statistical significance in adjusted odds ratios (ORs) as relative risk factors, and science course, measles/ rubella (MR) vaccination, and COVID-19 vaccination remained as relative protective factors in adjusted OR analyses. Club/group activities with member gathering and karaoke sing-along sessions in university students may frequently have WHO’s three Cs. These risk factors are still important topics for the infection control of COVID-19 in university students. Together with some recent reports from other researchers, the significant protective role of MR vaccine in our survey warrants further clinical investigation. If the breakthrough infection continuously constitutes the majority of infection, real data in test-negative case-control or web-based questionnaire design continue to be important for statistical analysis to determine the minimal requirement of our strategies which may be equivalent to or replace COVID-19 vaccines.

Chronic pain and itch are a pathological operation of the somatosensory system at the levels of primary sensory neurons, spinal cord and brain. Pain and itch are clearly distinct sensations, and recent studies have revealed the separate neuronal pathways that are involved in each sensation. However, the mechanisms by which these sensations turn into a pathological chronic state are poorly understood. A proposed mechanism underlying chronic pain and itch involves abnormal excitability in dorsal horn neurons in the spinal cord. Furthermore, an increasing body of evidence from models of chronic pain and itch has indicated that synaptic hyperexcitability in the spinal dorsal horn might not be a consequence simply of changes in neurons, but rather of multiple alterations in glial cells. Thus, understanding the key roles of glial cells may provide us with exciting insights into the mechanisms of chronicity of pain and itch, and lead to new targets for treating chronic pain and itch.
