RESUMO

A 23-y-old gelding was presented to a veterinary teaching hospital with a history of chronic, refractory diarrhea. Clinically, the horse was in poor body condition, with a thickened and corrugated large intestine identified by transcutaneous abdominal ultrasonography. At postmortem examination following euthanasia, the large colon and cecum had segmental thickening of the intestinal wall with innumerable mucosal ulcers and prominent polypoid mucosal masses. Many mesenteric and hepatic lymph nodes were enlarged. Histology revealed granulomatous and ulcerative typhlocolitis and granulomatous lymphadenitis with myriad acid-fast, variably gram-positive, intrahistiocytic bacilli that stained by immunohistochemistry for mycobacteria. Molecular testing by PCR and sequencing identified the causative agent as Mycobacterium genavense, which is an unusual presentation of infection in a horse.

RESUMO

Russell bodies are accumulation of immunoglobulin in plasma cells forming intracytoplasmic inclusions. Russell body colitis is rare with only 3 cases described in the English literature up to date. We report a 78-year-old male with cirrhosis showing prominent cecal infiltration of Russell body containing plasma cells. Plasma cells showed no nuclear atypia or mitoses, and no evidence of light chain restriction. In this article, we report a fourth case of Russell body colitis, that is unique in being localized to the cecum in contrast to the other 3, 1 of which was in an inflammatory polyp in the sigmoid colon, 1 in a rectal tubulovillous adenoma and 1 as part of diffuse gastrointestinal disease. This is therefore the first report of localized Russell body typhlitis, occurring in a cirrhotic patient in whom an adjacent erosion was likely nonsteroidal anti-inflammatory drug-associated, a combination that may have facilitated the formation of Russell bodies.

RESUMO

Neutropenic enterocolitis is also known as typhlitis, is characterized by severe inflammation in the bowel loops. It is often seen in immunosuppressed patients, and it has high morbidity and mortality. Although the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects the respiratory system and causes COVID-19 (Coronavirus Disease 2019), it may affect hematopoietic and gastrointestinal systems. Herein, we present a rare case of COVID-19-associated pancytopenia and typhlitis in a 60-year-old female who presented with abdominal pain. Contrast-enhanced abdominal computed tomography (CT) demonstrated the bowel wall thickening in the cecum and ascending colon compatible with enterocolitis. Moreover, the chest CT showed bilateral, peripheral, and multifocal ground-glass opacities, consistent with COVID-19 pneumonia. We also aimed to emphasize the laboratory, clinical, and CT findings of the patient.

RESUMO

A 22-year-old young woman presented with fever, lower abdominal pain and vomiting for 20 days. She had persistent fever and abdominal pain. Fever panel was negative. Clinical features were suggestive of subacute small bowel obstruction. Contrast-enhanced CT abdomen showed thickening of distal ileum, ileocaecal junction and caecum with conglomerate necrotic nodal mass in the ileocolic mesentry along with a lesion in the tail of pancreas. Patient was discussed with multidisciplinary team and decided to undergo a single-stage procedure after adequate nutritional optimisation. During optimisation, she underwent acute obstruction and hence taken up for emergency laparotomy proceeded to right haemicolectomy with distal pancreatectomy and splenectomy 4 weeks after the time of admission. Histopathology showed ileocaecal tuberculosis and solid pseudopapillary tumour with margins free of tumour. Approach of obstructed ileocaecal tuberculosis in the setting of incidental diagnosis of solid pseudopapillary tumour of pancreas in a moribund patient was challenging.

RESUMO

INTRODUCTION: Typhlitis is an abdominal complication of cancer chemotherapy, affecting mostly patients receiving intensive chemotherapeutic regimens with high potential to induce mucosal damage, such as patients with acute leukemia. Despite being relatively frequent, there are no randomized trials or high-quality cohort studies addressing important aspects of the diagnosis and management of the disease. Areas covered: In this review we discuss the gaps in the literature, acknowledging that the evidences for recommendations regarding the management of typhlitis are mostly expert opinion. We performed a computerized search of the MEDLINE database (PubMed version) for appropriate articles published from 1963 through July, 2016 in English language. Thereafter the reference lists of all identified studies were screened, reviewing the abstracts of all potentially pertinent articles for inclusion. Expert commentary: The diagnosis of typhlitis still relies on clinical and radiologic features consisting of fever, abdominal pain and thickness of a segment of the bowel wall, as seen by ultrasonography or CT scan. The treatment consists in antimicrobial therapy with a regimen that covers the most frequent pathogens, taking into consideration the local epidemiology. Other measures include bowel rest, and the use of G-CSF. Surgery is indicated only in selected situations.

RESUMO

Neutropenic colitis is a severe condition usually affecting immunocompromised patients. Its exact pathogenesis is not completely understood. The main elements in disease onset appear to be intestinal mucosal injury together with neutropenia and the weakened immune system of the afflicted patients. These initial conditions lead to intestinal edema, engorged vessels, and a disrupted mucosal surface, which becomes more vulnerable to bacterial intramural invasion. Chemotherapeutic agents can cause direct mucosal injury (mucositis) or can predispose to distension and necrosis, thereby altering intestinal motility. This article aims to review current concepts regarding neutropenic colitis' pathogenesis, diagnosis, and management.

RESUMO

Results of diagnosis and surgical treatment of 852 patients, suffering an acute appendicitis (AA) with atypical course, were analyzed. Retrocecal localization of appendix was noted in 61.2% of observations, a pelvic one ­ in 24.3%, medial ­ in 11.2%, and subhepatic ­ in 3.4%. Destructive forms of atypical AA were diagnosed in 92.5% patients, and various kinds of peritonitis ­ in 77.7%. Some diagnostic (rectal thermometry, test with ethanol) and operative methods (including laparoscopic) in destructive forms of AA, complicated by typhlitis, were improved and tested. Diagnostic­treatment algorithm, permitting to optimize tactic of treatment and to reduce the early postoperative complications rate from 9.9 tо 3.5% (р<0.001), was proposed.

RESUMO

Abdominal pain is common during chemotherapy for childhood leukemia. Clinically differentiating typhlitis from appendicitis can be difficult. We present an 8-year-old boy with abdominal pain in the setting of acute lymphoblastic leukemia and neutropenia. Following appendectomy for presumed appendicitis, pathology revealed appendiceal typhlitis. Diagnostic and treatment considerations are discussed.

RESUMO

This retrospective chart review describes pediatric patients with acute lymphoblastic leukemia or acute myeloid leukemia diagnosed between January 1999 and January 2008, who were identified with enteritis, typhlitis, or colitis. Among the acute leukemia patients, 33/449 (7.3%) with acute lymphoblastic leukemia and 13/89 (14.6%) with acute myeloid leukemia experienced 51 episodes of enteritis (n=8), typhlitis (n=15), colitis (n=19), or enterocolitis (n=9). Twenty-five (49%) patients were exposed to corticosteroids within 14 days of the episode and 35 (68.6%) had fever and neutropenia concurrent with the episode. Forty-eight (94%) patients were treated with complete bowel rest and broad-spectrum antibiotics. However, 3 patients received no therapy and had uneventful courses. Complications included sepsis in 7/51 (13.7%) and intestinal obstruction in 3/51 (5.9%). One child required surgery for abscess drainage and 2 children died of causes unrelated to their colitis. Enteritis, typhlitis, or colitis occurred in 8.6% of children treated for leukemia. The optimal management approach is uncertain.

RESUMO

AIM: To describe the symptoms, clinical management and short-term outcome in a series of paediatric oncology patients with severe typhlitis following conservative treatment. METHODS: Twelve episodes of severe typhlitis in 11 children with cancer treated at the paediatric oncology ward at Queen Silvias Children's Hospital between 1995 and 2006 were analysed retrospectively. Data on symptoms, radiological findings, laboratory status and treatment as well as outcome were collected and analysed. RESULTS: In all episodes, the classical signs of neutropenia, fever, abdominal pain and thickening of the bowel wall were present. All were successfully treated with bowel rest, broadspectrum antibiotics and supportive care. After recovery from typhlitis, three patients needed surgical intervention because of complications. CONCLUSION: A high clinical suspicion combined with radiological imaging aids early diagnosis. Predisposing factors for developing typhlitis were haematologic malignancy and treatment with chemotherapy within 3 weeks of onset. Supportive care, bowel rest including parenteral nutrition, correction of cytopenias and aggressive antimicrobial treatment is essential. Measurements of C-reactive protein in blood may be of benefit when assessing the clinical course.
