Efficacy and Findings of a Blinded Randomized Reintroduction Phase for the Low FODMAP Diet in Irritable Bowel Syndrome.

BACKGROUND & AIMS: The efficacy of a low fermentable oligo-, di-, monosaccharides and polyols (FODMAP) diet in irritable bowel syndrome (IBS) is well established. After the elimination period, a reintroduction phase aims to identify triggers. We studied the impact of a blinded reintroduction using FODMAP powders to objectively identify triggers and evaluated the effect on symptoms, quality of life, and psychosocial comorbidities. METHODS: Responders to a 6-week low FODMAP diet, defined by a drop in IBS symptom severity score (IBS-SSS) compared with baseline, entered a 9-week blinded randomized reintroduction phase with 6 FODMAP powders (fructans, fructose, galacto-oligosaccharides, lactose, mannitol, sorbitol) or control (glucose). A rise in IBS-SSS (≥50 points) defined a FODMAP trigger. Patients completed daily symptom diaries and questionnaires for quality of life and psychosocial comorbidities. RESULTS: In 117 recruited patients with IBS, IBS-SSS improved significantly after the elimination period compared with baseline (150 ± 116 vs 301 ± 97, P < .0001, 80% responders). Symptom recurrence was triggered in 85% of the FODMAP powders, by an average of 2.5 ± 2 FODMAPs/patient. The most prevalent triggers were fructans (56%) and mannitol (54%), followed by galacto-oligosaccharides, lactose, fructose, sorbitol, and glucose (respectively 35%, 28%, 27%, 23%, and 26%) with a significant increase in abdominal pain at day 1 for sorbitol/mannitol, day 2 for fructans/galacto-oligosaccharides, and day 3 for lactose. CONCLUSION: We confirmed the significant benefit of the low FODMAP diet in tertiary-care IBS. A blinded reintroduction revealed a personalized pattern of symptom recurrence, with fructans and mannitol as the most prevalent, and allows the most objective identification of individual FODMAP triggers.

Fitz-Hugh-Curtis syndrome associated with tuberculous salpingitis and peritonitis: a case presentation and review of literature.

BACKGROUND: Fitz-Hugh-Curtis syndrome or acute perihepatitis is considered a rare complication of pelvic inflammatory disease, mostly associated with chlamydial or gonococcal salpingitis. Peritoneal tuberculosis is a rare site of extra-pulmonary infection caused by Mycobacterium tuberculosis. Infection usually occurs after reactivation of latent tuberculous foci in the peritoneum and more seldom after contiguous spread from tuberculous salpingitis. CASE PRESENTATION: We describe a case of a 21-year old female of Somalian origin diagnosed with Fitz-Hugh Curtis syndrome associated with tuberculous salpingitis and peritonitis, presenting with new onset ascites. Acid fast stained smear and polymerase chain reaction for Mycobacterium tuberculosis on ascitic fluid, endocervical culture and tuberculin skin test were all negative. Eventually, the diagnosis was made laparoscopically, showing multiple peritoneal white nodules and perihepatic "violin string" fibrinous strands. CONCLUSIONS: To our knowledge, this is the first case where Fitz-Hugh-Curtis syndrome is associated with both peritoneal and genital tuberculosis and where ascites was the primary clinical finding. Female genital tuberculosis has only rarely been associated with Fitz-Hugh-Curtis syndrome and all cases presented with chronic abdominal pain and/or infertility. Ascites and peritoneal involvement was not present in any case. Moreover, most patients with Fitz-Hugh-Curtis syndrome show no evidence of generalized intra-abdominal infection and only occasionally have concomitant ascites.

Pancreatic panniculitis as a paraneoplastic phenomenon of a pancreatic acinar cell carcinoma.

We present the case of a 59-year-old patient admitted with extreme painful erythematous subcutaneous nodules of the lower extremities in association with arthritis and peripheral eosinophilia. Upon skin biopsy, the diagnosis of pancreatic panniculitis was made. On further investigation, an underlying acinar cell type pancreas carcinoma was revealed. This clinical case does illustrate how a seemingly innocuous skin condition may herald an underlying malignant disease. The presence of pancreatic panniculitis should trigger clinicians to undertake further thorough diagnostic investigation of the pancreas.

Dual disseminated infection with Nocardia farcinica and Mucor in a patient with systemic lupus erythematosus: a case report.

INTRODUCTION: Infections remain a major cause of morbidity and mortality in immunocompromised patients and require early diagnosis and treatment. However, correct diagnosis and treatment are often delayed by a multitude of factors. We report what we believe to be the first case of a combined disseminated infection with Nocardia and Mucor in a patient with systemic lupus erythematosus. CASE PRESENTATION: A 74-year-old Caucasian woman with systemic lupus erythematosus presented with recurrent pneumonia. Despite empirical treatment with antibiotics, her condition gradually deteriorated. Microbiological sampling by thoracoscopy revealed the presence of Nocardia. Despite the institution of therapy for disseminated nocardiosis, she died of multi-organ failure. A post-mortem investigation confirmed nocardiosis, but showed concomitant disseminated mucormycosis infection as well. CONCLUSION: Members of the bacterial genus Nocardia and the fungal genus Mucor are ubiquitous in the environment, have the ability to spread to virtually any organ, and are remarkably resistant to appropriate therapy. Both pathogens can mimic other pathologies both on clinical and radiological investigations. Invasive sampling procedures are often needed to prove their presence. Establishing a timely, correct diagnosis and a specific treatment is essential for patient survival.
