Small bowel tumors are detected in approximately 10% of patients with small bowel endoscopies for obscure or overt mid-intestinal bleeding. Small bowel tumors may be of malignant or benign etiology. Malignant etiologies include adenocarcinoma, neuroendocrine tumors, or lymphoma, whereas benign lesions are typically lipomas, inflammatory polyps, or adenomas. Within the group of nonneoplastic lesions inflammatory polyps are most frequent. Significant bleeding and bowel obstruction due to intussusception might occur, and surgical or endoscopic treatment has been reported for symptomatic patients. A case is demonstrated with an inflammatory fibroid polyp detected by capsule endoscopy and confirmed by balloon enteroscopy. This article is part of an expert video encyclopedia.
Peutz–Jeghers syndrome (PJS) is a rare autosomal-dominant inherited disorder characterized by gastrointestinal hamartomas, mucocutaneous pigmentation, and an elevated cancer risk. Moreover, intussusception risk may be as high as 50% at the age of 20 years and is caused by large polyps. There is some evidence that endoscopic surveillance of PJS patients with removal of small intestinal polyps with a diameter of more than 15 mm efficiently prevents intussusceptions. In recent years, capsule endoscopy (CE) has largely replaced small-bowel radiography techniques to screen for small-bowel polyps. Magnetic resonance imaging may be equally efficient as CE for screening of large polyps. Balloon enteroscopy may be used for endoscopic snare resection of polyps.

The author presents the case of a patient with severe bleeding from a duodenal ulcer that could not be controlled by endoscopic application of metal clips and injection of fibrin glue. Angiographic embolization with placement of coils into the feeding vessel stopped the bleeding. However, 3 days later, a fistula emerged from coil material penetrating into the dorsal duodenum and a peritoneal leakage developed. The fistula was completely closed by placing an over-the-scope clip on the enteral opening of the fistula. This article is part of an expert video encyclopedia.
Small-bowel tumors are rare and account for approximately 5% of all gastrointestinal tumors. Approximately 65% of small-bowel tumors are malignant, and approximately 40% of these tumors are adenocarcinomas. Similar to colorectal adenocarcinoma, premalignant adenomas of the small bowel may progress to carcinoma. This occurs both sporadically and in the context of hereditary tumor syndromes such as familial adenomatous polyposis or hereditary nonpolyposis colorectal cancer (Lynch syndrome). Herein cases with small-bowel adenocarcinomas visualized with both capsule endoscopy and double-balloon enteroscopy are presented. This article is part of an expert video encyclopedia.
The small intestine is a part of the gastrointestinal tract in which digestion and absorption of nutrients takes place. The small bowel follows the stomach and is followed by the large intestine, reaching from the pylorus to the valve of Bauhin and is separated into the duodenum, the jejunum, and the ileum.
Capsule endoscopy (CE) has the potential to offer a perfect overview of the small-bowel mucosa and complete visualization of the entire small bowel is achieved in most cases. In this video, there is an overview offered on normal findings in small-bowel CE and typical anatomical landmarks are indicated. This article is part of an expert video encyclopedia.
Small bowel varices may be found in less than 5% of patients with suspected small bowel bleeding. These varices are associated with portal hypertension or thrombosis of mesenteric venous vessels and with altered abdominal vascular anatomy with or without prior small bowel surgery. In bleeding small bowel varices, therapeutic options include endoscopic injection of tissue adhesives, endovascular approaches such as balloon-occluded retrograde transvenous or percutaneous obliteration and transjugular intrahepatic portosystemic shunt, and surgical resection. This is a case report of a 53-year-old patient with ethylic liver cirrhosis who presented with severe, life-threatening hematochezia due to small bowel varices. This article is part of an expert video encyclopedia.
This is an example of capsule endoscopy (CE) revealing terminal ileitis in an young male patient with recurrent abdominal pain who had previously been investigated with colonoscopy and esophagogastroduodenoscopy without any significant findings. CE revealed severe inflammation of the terminal ileum. This article is part of an expert video encyclopedia.
Background: One of the lesser recognized complications of diabetes mellitus are musculoskeletal (MSK) complications of the upper and lower extremity. No prevalence studies have been conducted in general practice. Thus, the aim of this study was to investigate the prevalence of upper extremity MSK disorders in patients with type 2 diabetes (T2DM) in the Netherlands. Methods: We conducted a cross-sectional study with two different approaches, namely a representative Dutch primary care medical database study and a questionnaire study among patients with T2DM. Results: In the database study, 2669 patients with T2DM and 2669 non-diabetes patients were included. MSK disorders were observed in 16.3% of patients with T2DM compared to 11.2% of non-diabetes patients (p < 0.001, OR 1.53, 95% CI 1.31, 1.80). In the questionnaire study, 200 patients with T2DM were included who reported a lifetime prevalence of painful upper extremity body sites for at least four weeks of 67.3%. Conclusion: We found that upper extremity MSK disorders have a high prevalence in Dutch patients with T2DM presenting in general practice. The prevalence ranges from 16% based on GP registered disorders and complaints to 67% based on self-reported diagnosis and pain. Early detection and treatment of these disorders may play a role in preventing the development of chronic MSK disorders.
Purpose: We aim to describe the sonographic uterine anatomy after a cesarean section (CS), test the reproducibility of predefined measurements from the BSUM study, and report the distribution of these measurements. Methods: This is a descriptive observational study where 200 women with a history of only one CS were recruited 12–24 months postoperatively. A 5–13 MHz micro-convex transvaginal transducer was used for the acquisition of volumetric datasets for evaluating the CS scars. We defined 15 distinct measurements including the residual myometrial thickness (RMT). RMT ratio was calculated as a percentage of RMT to the assumed pre-cesarean anterior uterine wall thickness. A P value below 0.05 is utilized for significant statistical analysis. Results: Patients were included on average 18.5 months post-cesarean. The uterus was anteflexed in 82.5% and retroflexed in 17.5%. Myometrial defects at the site of CS manifest in two forms, either as a niche or as fibrosis. Patients are classified into four groups: those with isolated niches (45%), combined niches and fibrosis (38.5%), isolated fibrosis (11%), and lacking both (5%). The median RMT ratio for these groups was 63.09, 40.93, 59.84, and 100% with a standard deviation of 16.73, 12.95, 16.59, and 0, respectively. The interclass correlation coefficient (ICC) remained above 0.9 for all distinct measurements among these groups except for those of RMT, where ICC varied between 0.47 and 0.96. The RMT ratio shows a constant ICC at 0.94 regardless of the group. Conclusion: The post-cesarean uterus is often anteflexed, and a myometrial loss of about 50% is normally expected. The pattern of this loss is in the form of a predominantly sharp-edged and echogenic niche, fibrosis, or a combination of both. The proposed RMT ratio takes these changes into consideration and results in a reproducible quantification. We hypothesize that different adverse outcomes could be attributed to the different scar patterns.
Aim: The aim of this study is to utilize the niche measurement guidelines outlined by Jordans et al. in order to establish normal values and accurate description of caesarean section scars in a normal population. After defining the normal distribution, abnormal pregestational scar characteristics will be identified for predicting adverse pregnancy outcomes. Methods: This is a prospective observational multicenter clinical study where women with a history of only one caesarean section and yet open family planning are enrolled. The uterine length, cervical length, niche length, niche depth, niche width, residual myometrial thickness, endometrial thickness, scar to internal os distance, anterior myometrial thickness superior and inferior to the scar and the posterior myometrial thickness opposite the scar, superior and inferior to it are measured in a pregestational uterus. The lower uterine segment is measured over a length of 3 cm during subsequent pregnancy and followed up until delivery. Results: Data from 500 patients will yield normal distribution curves for all predefined measurements. Establishing a correlation between deviations from the normal measures and adverse events would be instrumental for counseling women regarding subsequent pregnancy and mode of delivery.
Conclusion: This study will demonstrate the changes of the post-caesarean scar from a non-pregnant uterus until delivery and can confirm the importance of the scar characteristics in predicting pregnancy outcome.
Purpose: The aim of this study is to utilize the Manchester scar scale (MSS) and ultrasound in investigating the association between uterine wall defects and cutaneous scar characteristics after cesarean section (CS).
Methods: This is a prospective cohort study. The degree of myometrial loss was quantified by calculating a residual myometrial thickness (RMT) ratio as a percentage of RMT to the pre-cesarean anterior uterine wall thickness. Cutaneous scar assessment was performed according to the MSS. Spearman’s correlation and the Kruskal–Wallis test with a cut-off value of p < 0.05 were used for statistical analysis.
Results: Two hundred forty seven women, of which 2.4% had an Asian, 3.6% an Afro-American, 82% a Caucasian and 12% a Mediterranean background, were recruited. The RMT ratio ranged between 11.9 and 100% with a median of 55.8% and an average of 56%. MSS scores ranged from 4 to 13 with a median of 5 and an average of 6. Spearman’s correlation between MSS and RMT ratio show a rho of − 0.01 with a p value of 0.8. The correlation between MSS and RMT ratio within the four ethnical groups showed a p value between 0.3 and 0.8 and a rho between 0.8 and − 0.8. The Kruskal–Wallis test showed an eta2 of 0.13 and a p value of 0.0002 for the effect of ethnicity on MSS and an eta2 of 0.009 and a p value of 0.68 for the effect of ethnicity on the RMT ratio.
Conclusion: CS laparotomy scars heal differently between ethnical groups, but generally with satisfying results. Ethnicity does not affect myometrial healing and scar appearance does not reflect myometrial healing after CS. Thus, separate uterine sonographic assessment is recommended.
Purpose: The aim of this study was to investigate characteristics associated with ectopic pregnancy (EP) that could be utilized for predicting morbidity or mortality.
Methods: This was a retrospective analysis of pregnancy-related records from a tertiary center over a period of ten years. Data on age, gravidity, parity, EP risk, amenorrhea duration, abdominal pain presence and location, β-human chorionic gonadotropin (β-HCG) level, ultrasound findings, therapeutic intervention, exact EP implantation site and length of hospital stay (LOS) were obtained from the database. The LOS was used as a proxy for morbidity and was tested for an association with all variables. All statistical analyses were conducted with Stata® (ver. 16.1, Texas, USA).
Results: The incidence of EP in a cohort of 30,247 pregnancies over a ten-year period was 1.05%. Patients presented with lower abdominal pain in 87.9% of cases, and the likelihood of experiencing pain was tenfold higher if fluid was detectable in the pouch of Douglas. Only 5.1% of patients had a detectable embryonic heartbeat, and 18.15% had one or more risk factors for EP. While most EPs were tubal, 2% were ovarian. The LOS was 1.9 days, and laparoscopic intervention was the main management procedure. The cohort included one genetically proven dizygotic heterotopic pregnancy (incidence, 3.3 × 10− 5) that was diagnosed in the 7th gestational week. The only association found was between the β-HCG level and LOS, with a linear regression β coefficient of 0.01 and a P-value of 0.04.
Conclusion: EP is a relatively common condition affecting approximately 1% of all pregnancies. β-HCG correlates with EP-related morbidity, but the overall morbidity rate of EP is low regardless of the implantation site. Laparoscopic surgery is an effective therapeutic procedure that is safe for managing EP, even in cases of heterotopic pregnancy.
Objective: To assess the effect of cesarean section (CS) timing, elective versus unplanned, on the residual myometrial thickness (RMT) and CS scars. Methods: This is a prospective single-blinded observational cohort study with 186 observations. Patients indicated to undergo first singleton CS were preoperatively recruited. Exclusion criteria were history of repeated CS, vertical hysterotomy, diabetes, and additional uterine surgeries. Sonographic examination was performed for assessing the RMT ratio, the presence of a niche, fibrosis, and the distance from the scar to the internal os (SO) 1 year after CS. Power analysis was performed with 0.05 α, 0.1 β, and all statistical analyses were conducted with Stata®. Results: Wilcoxon rank-sum test for the association between CS timing, RMT ratio and SO showed Z values of −0.59 and −4.94 (P = 0.553 and P < 0.001), respectively. There was no association between CS timing and niches and fibrosis (P > 0.99 and P = 0.268, respectively). Linear regression between SO and the extent of cervical dilatation showed a −0.45 β (95% confidence interval −0.68 to −0.21) and a 10.22-mm intercept (P < 0.001). Conclusion: RMT is independent of the timing of CS, but the SO distance shows a negative linear relationship with the cervical dilatation.

Iron deficiency, with or without anemia, is the most frequent hematological manifestation in individuals with cancer, and is especially common in patients with colorectal cancer. Iron is a vital micronutrient that plays an essential role in many biological functions, in the context of which it has been found to be intimately linked to cancer biology. To date, however, whereas a large number of studies have comprehensively investigated and reviewed the effects of excess iron on cancer initiation and progression, potential interrelations of iron deficiency with cancer have been largely neglected and are not well-defined. Emerging evidence indicates that reduced iron intake and low systemic iron levels are associated with the pathogenesis of colorectal cancer, suggesting that optimal iron intake must be carefully balanced to avoid both iron deficiency and iron excess. Since iron is vital in the maintenance of immunological functions, insufficient iron availability may enhance oncogenicity by impairing immunosurveillance for neoplastic changes and potentially altering the tumor immune microenvironment. Data from clinical studies support these concepts, showing that iron deficiency is associated with inferior outcomes and reduced response to therapy in patients with colorectal cancer. Here, we elucidate cancer-related effects of iron deficiency, examine preclinical and clinical evidence of its role in tumorigenesis, cancer progression and treatment response. and highlight the importance of adequate iron supplementation to limit these outcomes.
Excessive accumulation of the extracellular matrix is a hallmark of many inflammatory and fibrotic diseases, including those of the kidney. This study addresses the question whether NO, in addition to inhibiting the expression of MMP-9, a prominent metalloprotease expressed by mesangial cells, additionally modulates expression of its endogenous inhibitor TIMP-1. We demonstrate that exogenous NO has no modulatory effect on the extracellular TIMP-1 content but strongly amplifies the early increase in cytokine-induced TIMP-1 mRNA and protein levels. We examined whether transforming growth factor beta (TGFbeta), a potent profibrotic cytokine, is involved in the regulation of NO-dependent TIMP-1 expression. Experiments utilizing a pan-specific neutralizing TGFbeta antibody demonstrate that the NO-induced amplification of TIMP-1 is mediated by extracellular TGFbeta. Mechanistically, NO causes a rapid increase in Smad-2 phosphorylation, which is abrogated by the addition of neutralizing TGFbeta antisera. Similarly, the NO-dependent increase in Smad-2 phosphorylation is prevented in the presence of an inhibitor of TGFbeta-RI kinase, indicating that the NO-dependent activation of Smad-2 occurs via the TGFbeta-type I receptor. Furthermore, activation of the Smad signaling cascade by NO is corroborated by the NO-dependent increase in nuclear Smad-4 level and is paralleled by increased DNA binding of Smad-2/3 containing complexes to a TIMP-1-specific Smad-binding element (SBE). Reporter gene assays revealed that NO activates a 0.6-kb TIMP-1 gene promoter fragment as well as a TGFbeta-inducible and SBE-driven control promoter. Chromatin immunoprecipitation analysis also demonstrated DNA binding activity of Smad-3 and Smad-4 proteins to the TIMP-1-specific SBE. Finally, by enzyme-linked immunosorbent assay, we demonstrated that NO causes a rapid increase in TGFbeta(1) levels in cell supernatants. Together, these experiments demonstrate that NO by induction of the Smad signaling pathway modulates TIMP-1 expression.
Background: The COVID-19 pandemic led to a higher incidence of depression and a worsening of psychiatric conditions, while pre-existing constraints of the healthcare system and safety regulations limited psychiatric care.
Aims: We investigated the impact of the pandemic on the clinical care of patients with a single episode (SE-MDD) or major depressive disorder (MDD) in Germany.
Methods: Nationwide inpatient data were extracted from the German Institute for Hospital Remuneration System for 2020 and 2021 (depression data) and the Robert Koch Institute (COVID-19 incidence). Changes in inpatients were tested with linear regression models. Local cases of depression in our department compared to 2019 were explored with one-way ANOVA and Dunnett's test.
Results: Across Germany, the inpatient numbers with both SE-MDD and MDD declined by more than 50% during three out of four COVID-19 waves. Higher COVID-19 incidence correlated with decreased inpatient numbers. In our department, fewer MDD inpatients were treated in 2020 (adj. p < 0.001) and 2021 (adj. p < 0.001) compared to 2019, while the number of SE-MDD inpatients remained stable. During this period fewer elective and more emergency inpatients were admitted. In parallel, MDD outpatient admissions increased in 2021 compared to 2019 (adj. p = 0.002) and 2020 (adj. p = 0.003).
Conclusion: During high COVID-19 infection rates, MDD patients received less inpatient care, which might cause poor outcomes in the near future. These data highlight the necessity for improved infrastructure in the in- and outpatient domains to facilitate accessibility to adequate care.
Highlights
• Inflammatory monocyte genes were used to stratify patients in a RCT with statins.
• One group (∼30% SSD patients) showed a distinct inflammatory monocyte signature.
• Within this “inflammatory” group, statins improved PANSS scores.
• Such changes were not observed for “inflammatory” patients receiving placebo.
• Depression scores in the “inflammatory” group improved during treatment as usual.
Abstract
Immune dysregulation has been reported in schizophrenia spectrum disorders (SSD). In the past decade, several trials using anti-inflammatory agents for treatment of SSD have been completed, with so far limited success. One such anti-inflammatory agent used is simvastatin. A recent, large-scale, randomized controlled trial with simvastatin augmentation failed to show improvement in the predefined primary outcome. However, baseline inflammatory profiles were not taken into account. Here we employed a data-driven clustering approach to investigate whether patients with an inflammatory monocyte gene signature respond better to add-on simvastatin treatment than those without such a signature, over a treatment period of 2 years. In 61 patients (60 randomized, 1:1 placebo:simvastatin) and healthy controls, a previously validated monocyte gene expression signature was assessed using quantitative polymerase chain reaction. Resulting delta cycle threshold values were used to identify patient clusters. Two major patient clusters with either up- or downregulated pro-inflammatory factors were detected. Linear mixed models showed a significant three-way interaction between the inflammatory cluster, treatment, and time for psychotic symptoms. Only patients treated with simvastatin who were in the inflammatory group, showed a consistent improvement: symptom severity gradually decreased after 3 months and reached significance after 12 and 24 months compared to baseline (p.adj<0.05). The effects were small, and overall between-group effects were not significant. Here, we show that patient stratification based on inflammatory gene expression might be useful to select appropriate treatment augmentation for patients with SSD, highlighting the need for precision medicine approaches. Our findings corroborate the results of the primary analyses, showing that in the overall group, simvastatin was not effective; however, at the individual level the treatment might make a difference.
Background: During the current second wave of COVID-19, the radiologists are expected to face great challenges in differentiation between COVID-19 and other virulent influenza viruses, mainly H1N1. Accordingly, this study was performed in order to find any differentiating CT criteria that would help during the expected clinical overlap during the current Influenza season.
Results: This study was retrospectively conducted during the period from June till November 2020, on acute symptomatic 130 patients with no history of previous pulmonary diseases; 65 patients had positive PCR for COVID-19 including 50 mild patients and 15 critical or severe patients; meanwhile, the other 65 patients had positive PCR for H1N1 including 50 mild patients and 15 critical or severe patients. They included 74 males and 56 females (56.9%:43.1%). Their age ranged 14–90 years (mean age 38.9 ± 20.3 SD). HRCT findings were analyzed by four expert consultant radiologists in consensus. All patients with COVID-19 showed parenchymal or alveolar HRCT findings; only one of them had associated airway involvement. Among the 65 patients with H1N1; 56 patients (86.2%) had parenchymal or alveolar HRCT findings while six patients (9.2%) presented only by HRCT signs of airway involvement and three patients (4.6%) had mixed parenchymal and airway involvement. Regarding HRCT findings of airway involvement (namely tree in bud nodules, air trapping, bronchial wall thickening, traction bronchiectasis, and mucous plugging), all showed significant p value (ranging from 0.008 to 0.04). On the other hand, HRCT findings of parenchymal or alveolar involvement (mainly ground glass opacities) showed no significant relation.
Conclusion: HRCT can help in differentiation between non-severe COVID-19 and H1N1 based on signs of airway involvement.
Fallzahlaufkommen und Qualitätsindikatoren bei der Versorgung des abdominellen Bauchaortenaneurysmas
(2020)
Hintergrund: Der MTL30 (Mortalität, Transfer, Liegezeit) wurde als Surrogatparameter zur Evaluation der Qualität potenziell komplikationsträchtiger viszeralchirurgischer Eingriffe vorgeschlagen.
Zielsetzung: Es wurde überprüft, inwieweit sich der MTL30 zu den Ergebnissen des Bauchaortenaneurysma(AAA)-Registers des Deutschen Instituts für Gefäßmedizinische Gesundheitsforschung (DIGG) der Deutschen Gesellschaft für Gefäßchirurgie und Gefäßmedizin (DGG) und zum Fallaufkommen der Kliniken korrelieren lässt.
Material und Methoden: Insgesamt 14.282 Patienten wurden endovaskulär (EVAR) und 3923 Patienten offen (OAR) elektiv wegen eines AAA versorgt. Bestimmt wurden Fallaufkommen der behandelnden Kliniken, Klinikletalität, Liegezeit und Verlegung in ein anderes Akutkrankenhaus 30 Tage nach dem Indexeingriff.
Ergebnisse: Die Klinikletalität machte bei EVAR 1,3 %, bei OAR 4,9 % aus (p = 0,000), der MTL30 5,0 % vs. 14,4 % (p = 0,000). Für EVAR ließ sich keine Beziehung zwischen Fallaufkommen und Klinikletalität (Quintile 1: 1,0 %; Quintile 5: 1,3 %) sowie Fallaufkommen und MTL30 (Quintile 1: 5,3 %; Quintile 5: 5,3 %) nachweisen. Auch bei OAR bestand keine signifikante Beziehung zwischen Fallaufkommen und Klinikletalität (Quintile 1: 5,8 %, Quintile 5: 3,5 %; p = 0,505) und Fallaufkommen und MTL30 (Quintile 1: 16,4 %, Quintile 5: 12,2 %, p = 0,110). Bei einer Klinikletalität von 7,2 (5–10) % betrug der MTL30 bei OAR 17,6 %. Sowohl bei EVAR als auch bei OAR korrelierte die stationäre Aufenthaltsdauer signifikant mit Klinikletalität und MTL30.
Diskussion: Eine eindeutige Beziehung zwischen Krankenhausfallaufkommen und Klinikletalität ließ sich im AAA-Register des DIGG nicht aufzeigen. Das gleiche galt für den MTL30. Ob demnach der MTL30 gegenüber der Erfassung von Klinikletalität und stationärer Liegezeit als Qualitätsparameter einen Zusatznutzen bietet, muss offenbleiben.
