Purpose:
To investigate urothelial cell proliferation, cytoskeleton, inflammation, and barrier function protein expressions in patients with interstitial cystitis/bladder pain syndrome (IC/BPS) after intravesical platelet-rich plasma (PRP) injections
Methods:
A total of 19 patients with IC/BPS underwent 4 monthly intravesical PRP injections. Bladder biopsies were taken at the first and fourth PRP treatment. The bladder specimens were analyzed using the Western blot and immunochemical staining for progenitor cell markers for sonic hedgehog (Shh), CD34, and cytoskeleton proteins cytokeratin 5 (CK5), CK14, CK20; barrier function markers for zonula occludens-1 (ZO-1), E-cadherin, and intercellular adhesive molecule-1, tryptase and transforming growth factor-β (TGF-β). Global response assessment (GRA) was used to evaluate treatment outcomes.
Results:
The mean age of patients was 55.6 years. After PRP injections, the functional bladder capacity and maximum flow rate increased, and the visual analogue scale (VAS) of pain, interstitial cystitis (IC) symptom index, IC problem index, O’Leary-Sant symptom score, and GRA improved in all patients. Urothelium Shh, CK5, ZO-1, E-cadherin, and TGF-β expressions increased significantly after repeated PRP injections. By subgrouping, according to PRP treatment outcomes, significant increases in Shh, E-cadherin, and ZO-1 expressions were noted only in patients with GRA ≥1 or improved VAS, but not in patients with GRA=0 and no improvement in VAS.
Conclusions
The level of urothelial barrier function protein and cell proliferation protein expression in the patients with IC/BPS was increased after repeat intravesical PRP injections. Intravesical repeat PRP injections may have potential to improve urothelial health and result in symptoms improvement in the patients with IC/BPS.
3.Foley balloons’ tamponade is an effective method for controlling massive pelvic bleeding during colorectal surgery
Annals of Coloproctology 2022;38(1):69-71
Purpose:
Hemostasis can be achieved by various methods, but it can be difficult to stop active bleeding in the pelvis. An effective method is described to stop massive active bleeding in the pelvis during colorectal surgery.
Methods:
When there were massive bleedings in the pelvis, 3 to 5 Foley catheters were inserted through stab wounds on the abdomen. The tips of catheters were placed in the pelvis. Each balloon was inflated with 40 mL of sterile water. The water inside each balloon was removed gradually from the third postoperative day. If there is no further bleeding, all catheters were removed on the 7th postoperative day.
Results:
There were 8 patients (4 males and 4 females) with massive pelvic bleeding encountered from January 1998 to December 2018. Four patients underwent low anterior resection for primary rectal cancer, 2 patients for colon cancer with pelvic recurrence, 1 patient for ovary cancer with pelvic recurrence, and 1 patient for presacral parachordoma with a bleeding tendency. All of the patients survived without further bleeding after surgery.
Conclusion
The technique is a simple method to control massive pelvic bleeding during colorectal surgery. It is also inexpensive and effective even in patients with a bleeding tendency.

PURPOSE: The urinary bladder (UB) is innervated by both sensory and autonomic nerves. Recent studies have shown that sensory neuropeptides induced contractions in the detrusor muscle. Therefore, in a mouse model, we investigated the presence of interactions between the submucosal sensory nerves and the autonomic nerves that regulate the motor function of the detrusor muscle. METHODS: UB samples from male C57BL/6 mice were isolated, cut into strips, and mounted in an organ bath. Dose-response curves to norepinephrine and phenylephrine were studied in UB strips with and without mucosa, and the effects of preincubation with a receptor antagonist and various drugs on relaxation were also studied using tissue bath myography. RESULTS: Phenylephrine-induced relaxation of the UB strips showed concentration-related effects. This relaxation appeared in both mucosa-intact and mucosa-denuded UB strips, and was significantly inhibited by lidocaine, silodosin, and guanethidine (an adrenergic neuronal blocker). Meanwhile, phenylephrine-induced relaxation was inhibited by pretreatment with propranolol and calcitonin gene-related peptide (CGRP)–depletory capsaicin in UB strips with and without mucosa. CONCLUSIONS: The present study suggests that phenylephrine activates the α-1A adrenergic receptor (AR) of the sensory nerve, and then activates capsaicin-sensitive sensory nerves to release an unknown substance that facilitates the release of norepinephrine from adrenergic nerves. Subsequently, norepinephrine stimulates β-ARs in the detrusor muscle in mice, leading to neurogenic relaxation of the UB. Further animal and human studies are required to prove this concept and to validate its clinical usefulness.

Background and Objectives:
The impact of off-hours admission (such as weekends, nighttime, and non-working hours) vs. regular hours (weekdays and daytime working hours) on the mortality risk of patients undergoing surgery for type A aortic dissection (TAAD) repair is still uncertain. To address this uncertainty, we undertook a comprehensive systematic review and meta-analysis. We aimed to assess the potential link between off-hours admission and the risk of mortality in patients undergoing TAAD repair surgery.
Methods:
We conducted a thorough search of the PubMed, Embase, and Cochrane Library databases, covering the period from their inception to May 20, 2023. Our inclusion criteria encompassed all studies that examined the potential relationship between off-hour admission and mortality in individuals who had undergone surgery for TAAD repair. The odds ratios (ORs) were extracted and combined utilizing a random effects model for our synthesis.
Results:
Nine studies with 16,501 patients undergoing TAAD repair surgery were included in the meta-analysis. Overall, patients who underwent surgery during the weekend had higher in-hospital mortality (pooled OR, 1.41; 95% confidence interval [CI], 1.14–1.75; p=0.002) than those treated on weekdays. However, the mortality risks among patients who underwent TAAD surgery during nighttime and non-working hours were not significantly elevated compared to daytime and working hours admission.
Conclusions
Weekend surgery for TAAD was associated with a higher in-hospital mortality risk than weekday surgery. However, further studies are warranted to identify and develop strategies to improve the quality of round-the-clock care for patients with TAAD.

BACKGROUND/AIMS: Only moderate to severe Crohn's Disease (CD) patients without a satisfactory conventional therapy effect are eligible to get reimbursement from the National Health Insurance of Taiwan for using adalimumab. These are more stringent criteria than in many Western countries and Japan and Korea. We aim to explore the efficacy of using adalimumab in CD patients under such stringent criteria. METHODS: A retrospective analysis was conducted in nine medical centers in Taiwan and we collected the results of CD patients receiving adalimumab from Sep 2009 to Mar 2014. The clinical characteristics, response measured by CDAI (Crohn's Disease Activity Index), adverse events and survival status were recorded and analyzed. CR-70, CR-100, and CR-150 were defined as attaining a CDAI decrease of 70, 100 or 150 points compared with baseline. RESULTS: A total of 103 CD patient records were used in this study. Sixty percent of these patients received combination therapy of adalimumab together with immunomodulators. CR-70 was 68.7%, 74.5% and 88.4% after week 4, 8 and 12 of treatment, respectively. The steroid-free rate, complications and survival were 47.6%, 9.7% and 99% of patients, respectively. In considering the mucosal healing, only 25% patients achieve mucosal healing after treatment for 6 to12 months. Surgery was still needed in 16.5% of patients. Combination treatment of adalimumab with immunomodulators further decreased the level of CDAI at week 8 when compared with the monotherapy. CONCLUSIONS: Even under the stringent criteria for using adalimumab, the response rate was comparable to those without stringent criteria.

Crohn's disease (CD) is a chronic relapsing and remitting inflammatory disease of the gastrointestinal tract. CD is rare in Taiwan and other Asian countries, but its prevalence and incidence have been steadily increasing. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of CD taking into account currently available evidence and the expert opinion of the committee. Thorough clinical, endoscopic, and histological assessments are required for accurate diagnosis of CD. Computed tomography and magnetic resonance imaging are complementary to endoscopic evaluation for disease staging and detecting complications. The goals of CD management are to induce and maintain remission, reduce the risk of complications, and improve quality of life. Corticosteroids are the mainstay for inducing re-mission. Immunomodulating and biologic therapies should be used to maintain remission. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to treatment and receive regular surveillance for cancer. These consensus statements are based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of patients with CD in Taiwan.

Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic mucosal inflammation of the colon, and the prevalence and incidence of UC have been steadily increasing in Taiwan. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of UC taking into account currently available evidence and the expert opinion of the committee. Accurate diagnosis of UC requires thorough clinical, endoscopic, and histological assessment and careful exclusion of differential diagnoses, particularly infectious colitis. The goals of UC therapy are to induce and maintain remission, reduce the risk of complications, and improve quality of life. As outlined in the recommended treatment algorithm, choice of treatment is dictated by severity, extent, and course of disease. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to immunosuppressive treatment, especially with steroids and biologic agents, and should be regularly monitored for reactivation of latent infection. These consensus statements are also based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of UC in Taiwan.
