Syphilis is a sexually transmitted disease, caused by the spirochete Treponema Pallidum. Many different manifestations exist, which can complicate diagnosis.A 36-year-old man with a known HIV infection, presented himself with rectal blood loss and abdominal pain. Abdominal ultrasound and abdominal CT were suspicious for malign liver metastases. During subsequent colonoscopy, benign looking rectal lesions were found, possibly caused by either lymphogranuloma venereum or syphilis. Additional diagnostics confirmed an active syphilis infection. After treatment with benzylpenicillin, patient's complaints resolved, as well as the lesions in rectum and liver.We describe a rare case of a patient with secondary syphilis, presenting with rectal lesions and liver lesions suspicious for malign metastases.

IntroductionIdiopathic acute pancreatitis (IAP) remains a dilemma for physicians as it is uncertain whether patients with IAP may actually have an occult aetiology. It is unclear to what extent additional diagnostic modalities such as endoscopic ultrasonography (EUS) are warranted after a first episode of IAP in order to uncover this aetiology. Failure to timely determine treatable aetiologies delays appropriate treatment and might subsequently cause recurrence of acute pancreatitis. Therefore, the aim of the Pancreatitis of Idiopathic origin: Clinical added value of endoscopic UltraSonography (PICUS) Study is to determine the value of routine EUS in determining the aetiology of pancreatitis in patients with a first episode of IAP.Methods and analysisPICUS is designed as a multicentre prospective cohort study of 106 patients with a first episode of IAP after complete standard diagnostic work-up, in whom a diagnostic EUS will be performed. Standard diagnostic work-up will include a complete personal and family history, laboratory tests including serum alanine aminotransferase, calcium and triglyceride levels and imaging by transabdominal ultrasound, magnetic resonance imaging or magnetic resonance cholangiopancreaticography after clinical recovery from the acute pancreatitis episode. The primary outcome measure is detection of aetiology by EUS. Secondary outcome measures include pancreatitis recurrence rate, severity of recurrent pancreatitis, readmission, additional interventions, complications, length of hospital stay, quality of life, mortality and costs, during a follow-up period of 12 months.Ethics and disseminationPICUS is conducted according to the Declaration of Helsinki and Guideline for Good Clinical Practice. Five medical ethics review committees assessed PICUS (Medical Ethics Review Committee of Academic Medical Center, University Medical Center Utrecht, Radboud University Medical Center, Erasmus Medical Center and Maastricht University Medical Center). The results will be submitted for publication in an international peer-reviewed journal.Trial registration numberNetherlands Trial Registry (NL7066). Prospectively registered.

Objective. To assess the accuracy of a new ingestion protocol for capsule endoscopy (CE) in evaluating patients with gastro-oesophageal reflux disease (GORD). Methods. Oesophago-gastroduodenoscopy (OGD) was performed 1 week prior to CE. The first 28 subjects swallowed the capsule following the original ingestion protocol (OIP) and the subsequent 30 subjects following a simplified ingestion protocol (SIP). CE videos were reviewed by two independent investigators who were blinded to the OGD findings. Results. Of 48 patients included, 24 were diagnosed with reflux oesophagitis (67% male, mean age 49.5 +/- 13 years) and 24 with Barrett oesophagus (BO) (88% male, 55.6 +/- 10 years) by OGD. In addition, 10 asymptomatic healthy controls (50% male, 45.8 +/- 7.1 years) were included. Oesophageal transit time was faster in patients using the SIP compared to the OIP (126 +/- 26 s versus 214 +/- 33; p=0.04). Complete evaluation of the Z-line was possible in 19/28 (68%) of the OIPs compared to 28/30 (93%) of the SIPs (p=0.04). Sensitivity for detecting any oesophageal abnormality was higher in the SIP group than in the OIP group (97% versus 89%; p=0.11). Overall, CE detected oesophagitis in 22/24 patients (sensitivity, 92%; specificity, 88%) and BO in 23/24 patients (sensitivity, 96%; specificity, 91%). Furthermore, 41/44 (93%) preferred CE over OGD and experienced less discomfort and pain during CE. Conclusion. CE is an accurate method for detecting mucosal oesophageal abnormalities. The new ingestion protocol improves the visualization of the Z-line, which is likely to increase the diagnostic yield of CE.
