Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) that is thoroughly studied and known to have a strong genetic component. It affects the mucosa and submucosa of the colon and rectum, causing diffuse friability and superficial erosions leading to bleeding. Common presenting symptoms include diarrhea that is often bloody or purulent and abdominal pain or cramping. There are also extraintestinal manifestations of UC such as cutaneous rashes, eye inflammation, and oral ulceration. A rarer manifestation of IBD is myositis, either dermatomyositis, polymyositis, or even rhabdomyolysis. Based on the literature review, myositis has been documented more so in cases of Crohn\'s disease versus UC. In this report, we discuss a patient with known UC who presented during a flare and subsequently complained of diffuse myalgia. She was found to have an elevated creatine kinase (CK), thus suggesting some form of myositis. We will review possible pathogenesis and other cases of UC presenting with myositis that have been documented.

Although colorectal cancer (CRC) surveillance is embedded in clinical inflammatory bowel disease (IBD) practice, a subset of patients still develops advanced neoplasia (AN) (high-grade dysplasia [HGD] and/or CRC). We aimed to assess the impact of surveillance quality on AN risk in IBD.
In this multicenter case-control study, we searched the Dutch nationwide pathology databank to identify IBD cases with AN and controls with indefinite or low-grade dysplasia. The surveillance colonoscopy preceding the index lesion (first indefinite for dysplasia [IND]/low-grade dysplasia [LGD] or AN) was used to assess the impact of surveillance quality. We assessed intervals, bowel preparation, cecal intubation, and absence of inflammation as primary quality indicators. In addition, we assessed chromoendoscopy, endoscopist expertise, hospital setting, and biopsy strategy. Associations of quality indicators with AN risk were determined with multivariable logistic regression analyses with Firth\'s correction.
We included 137 cases and 138 controls. Delayed intervals (58.2% vs 39.6%) and active inflammation (65.3% vs 41.8%) were frequently present in cases and controls and were associated with AN (delayed interval: adjusted odds ratio [aOR], 2.00; 95% confidence interval [CI], 1.07-3.81; P = .03; active inflammation: aOR, 2.46; 95% CI, 1.33-4.61; P < .01). Surveillance compliant with primary quality indicators was associated with a reduced AN risk (aOR, 0.43; 95% CI, 0.22-0.91; P = .03), similar to chromoendoscopy (OR, 0.11; 95% CI, 0.01-0.89; P = .01). Other indicators were not significantly associated with AN.
Surveillance compliant with primary quality indicators is associated with a reduced colitis-associated AN risk. Delayed surveillance intervals and active inflammation were associated with an increased AN risk. This underlines the importance of procedural quality, including endoscopic remission to optimize the effectiveness of endoscopic surveillance.

BACKGROUND: Strongyloides colitis is a severe form of strongyloidiasis that carries a high mortality rate if untreated. There is an overlapping clinical presentation between Strongyloides colitis and Crohn\'s disease. Here, we present a case of a patient who was diagnosed with Crohn\'s disease and was treated with immunosuppressant therapy which resulted in a poor outcome.
METHODS: A middle-aged, native African male presented with diarrhea, abdominal pain, and weight loss. Colonoscopy showed some patchy inflammation in the caecum, which on biopsy was suggestive of Crohn\'s disease. He had a short course of steroids before being admitted to an emergency with abdominal pain, diarrhea, malnutrition, and severe weight loss. Initial conservative treatment failed, and he became acutely unwell and septic with peritonitis. Laparotomy was carried out, which showed mild inflammation in the terminal ileum, which was not resected. Postoperatively, the patient became comatose and went into multi-organ dysfunction. He failed to progress, and a further laparotomy and subtotal colectomy were performed on the 12th postoperative day. His multi-organ failure progressed, and he succumbed to death 4 days later.
CONCLUSIONS: Strongyloides stercoralis is a parasite causing an enteric infection in animals and humans. Strongyloidiasis in immunocompetent individuals is usually an indolent disease. However, in immunocompromised individuals, it can cause hyperinfective syndrome. Patients with strongyloid colitis should undergo colonoscopy and biopsy where acute inflammation with eosinophilic infiltrates indicates parasitic infiltration of the colonic wall. Surgery is generally not indicated, and any surgical intervention with misdiagnosis of a flare-up of IBD can be very detrimental to the patient.
CONCLUSIONS: Strongyloid colitis can very harmfully mimic Crohn\'s colitis, and the use of steroids and immunosuppressants can disseminate parasitic infection. Hyperinfection syndrome can lead to sepsis, organ dysfunction, and comma. Disseminated infection carries a high mortality.

Crohn\'s disease (CD) has an unknown etiology, but it has a genetic component. Many cases of familial CD have been reported. We describe a Kosovar Albanian family with 6 children, of whom 3 have CD: monozygotic twins and their sister. As far as we know, this is the first such report of CD within a Kosovar family.

Traditional cigarette use adversely impacts disease outcomes in Crohn\'s disease (CD). There has been a worldwide increase in the use of e-cigarettes over the past decade. The impact of use of nicotine containing e-cigarettes on disease outcomes in CD or ulcerative colitis (UC) has not been well defined.
This was a retrospective case-control study of patients with CD or UC who were current users of nicotine containing e-cigarettes (cases). Each case was matched to two non-vaping controls. Our primary study outcome was a composite of new biologic initiation, switch of existing biologic therapy, or IBD-related hospitalization or surgery over 2 years. Multivariable models adjusting for relevant covariates were construction.
The study consisted of 127 patients with IBD who were current e-cigarette users compared to 251 controls. Current e-cigarette users were younger than non-users and were more likely to have had an IBD-related surgery previously. On multivariable analysis among those with CD, current e-cigarette use was not associated with higher risk of study outcome (OR 0.82, 95% CI 0.36-1.87). No difference was observed separately among those who were current or former smokers. Similarly, in those with UC, current e-cigarette use was not associated with the primary outcome (OR 1.05, 95% CI 0.33-3.39).
Current e-cigarette use was not associated with worse outcomes among patients with IBD. However, larger studies particularly of patients de novo initiating vaping are needed to draw robust conclusions. Patients should be discouraged from initiating vaping recognizing overall adverse health effects.

More than 80% of ingested foreign bodies are thought to pass spontaneously in the faeces, with fewer than 1% requiring surgical intervention. \'Missed\' gastrointestinal foreign bodies are rare and often due to the lack of an obtainable history in patients with communication difficulties or radiolucent foreign bodies. We present the rare case of a 27-year-old woman with severe learning difficulties and a complex surgical history who presented with a 2-year history of increasing abdominal discomfort due to a \'missed\' foreign body. Initially diagnosed as Crohn\'s disease, this case highlights the value of oral contrast enhancement imaging in patients who do not fit a \'classical\' inflammatory bowel disease presentation.

Gastrointestinal diaphragm disease is a rare entity characterized by the formation of thin membranous circumferential mucosal septa, resulting in marked narrowing of the intestinal lumen. The most frequent etiology is the chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs). Idiopathic cases and other possible etiologies have been reported. We present a rare association of diaphragm disease with Crohn\'s disease in a boy without a history of significant NSAID usage.

BACKGROUND: Incidence of hernial appendicitis is 0.008%, most frequently within inguinal and femoral hernias. Up to 2.5% of appendectomy patients are found to have Crohn\'s disease. Elucidating the etiology of inflammation is essential for directing management.
METHODS: A 51-year-old female with achondroplastic dwarfism, multiple cesarean sections, and subsequent massive incisional hernia, presented with ruptured appendicitis within her incarcerated hernia. She underwent diagnostic laparoscopy, appendectomy, intra-abdominal abscess drainage, and complete reduction of ventral hernia contents. She developed a nonhealing colocutaneous fistula, causing major disruptions to her daily life. She elected to undergo hernia repair with component separation for anticipated lack of domain secondary to her body habitus. Her operative course consisted of open abdominal exploration, adhesiolysis, colocutaneous fistula repair, ileocolic resection and anastomosis, and hernia repair with bioresorbable mesh. She tolerated the procedure well. Unexpectedly, ileocolic pathology demonstrated chronic active ileitis, diagnostic of Crohn\'s disease.
CONCLUSIONS: Only two cases of hernial Crohn\'s appendicitis have been reported, both within Spigelian hernias. Appendiceal inflammation inside a hernia sac may be attributed to ischemia from extraluminal compression of the hernia neck. This case demonstrates a rare presentation of multiple concurrent surgical disease processes, each of which impact the patient\'s treatment plan.
CONCLUSIONS: This is the first report of incisional hernia appendicitis with nonhealing colocutaneous fistulas secondary to Crohn\'s. It is a lesson in developing a differential diagnosis of an inflammatory process within an incarcerated hernia and management of the complications related to laparoscopic hernial appendectomy in a patient with undiagnosed Crohn\'s disease.

BACKGROUND: Tumor necrosis factor-α (TNF-α) inhibitors, such as infliximab, adalimumab, and certolizumab pegol are effective agents in the treatment of inflammatory bowel disease. Some individuals undergoing anti-TNF-α therapy for Crohn\'s disease or ulcerative colitis develop psoriasiform lesions. This is a paradoxical finding, as classical psoriasis is known to respond to these agents.
OBJECTIVE: The clinical features of anti-TNF-α-induced psoriatic dermatitis are described.
METHODS: A 60-year-old man with Crohn\'s disease treated with infliximab, who developed anti-TNF-α-induced psoriasiform dermatitis, is described.
RESULTS: The man developed erythematous skin lesions in the bilateral axillae two years after beginning infliximab treatment for Crohn\'s disease. Biopsy revealed psoriasiform dermatitis, consistent with a diagnosis of anti-TNF-α-induced psoriasiform dermatitis. He was treated with clobetasol 0.05% ointment twice daily for two weeks and had significant improvement. Subsequently, he used the corticosteroid ointment two days per week and calcipotriene 0.005% ointment twice daily for five days per week to achieve and maintain clear skin.
CONCLUSIONS: Anti-TNF-α-induced psoriasiform dermatitis is an infrequent complication of infliximab therapy. However, the condition may require discontinuation of the anti-TNF-α agent. Anti-TNF-α-induced psoriasiform dermatitis should be considered in the differential diagnosis when evaluating a new erythematous skin condition in an individual with a history of inflammatory bowel disease who is being treated with a TNF-α inhibitor.
