Treatment of Helicobacter pylori infection 14-day concomitant quadruple therapy versus triple therapy: A parallel double-blind randomized controlled trial.

Background and Aims: Successful Helicobacter pylori (Hp) eradication with the traditional 7-day course of proton pump inhibitor triple therapy is declining. Prolonging therapy to 14 days is associated with better eradication rates. Most learned societies recommend concomitant quadruple therapy (QC) as a first-line alternative therapy for this bacterial infection. The aim of this study is to compare the efficacy and safety of triple therapy (TT) and QC for the eradication of Hp infection. Methods: A parallel double-blind randomized controlled trial was conducted. The diagnosis of Hp infection was made by pathological examination of gastric biopsies. Patients were randomly assigned to two treatment groups: either QC (esomeprazole 80 mg, amoxicillin 2000 mg, clarithromycin 1000 mg, and metronidazole 1000 mg daily) or triple therapy (esomeprazole 80 mg, amoxicillin 2000 mg, and clarithromycin 1000 mg daily in divided doses) for 14 days. The efficacy of the treatment is defined by Hp eradication attested by a negative breath test performed 6 weeks after the completion of treatment. Treatment outcomes were compared using the chi-square test, while binary logistic regression identified predictors of treatment failure. Results: Ninety-two patients were included. Forty-two patients belonged to the QC group and 50 to the TT group. No significant difference was noted between the two groups concerning the rate of Hp eradication either by intention to treat (81% vs. 72% respectively, p = 0.31) or per protocol (81.6% vs. 76.1% respectively, p = 0.54). Likewise, there was no difference between the two groups in terms of tolerance to treatment (59.5% for QC vs. 58% for TT, p = 0.88). No factor has been associated with treatment failure. Conclusion: There was no significant difference in the rate of HP eradication between the QC and the 14-day triple therapy. Neither regimen should be used topically because of their low eradication rates.

Burkitt's Thyroid Lymphoma Revealed in a Pregnant Woman With Acute Dyspnea.

Extraganglionic Burkitt's lymphoma is rare. Primary thyroid localization accounts for 1% to 5% of malignant tumors of the thyroid gland. The association of Burkitt's lymphoma and pregnancy is even rarer. Our patient was pregnant at 36 weeks. She was brought to the emergency department with anterior cervical swelling, rapidly increasing in volume and becoming compressive for 15 days, in addition to dysphonia and inspiratory dyspnea. Cervical ultrasound and computed tomography scan revealed a compressive and plunging goiter. Surgery attempted after fetal extraction proved impossible due to massive tumor infiltration into adjacent structures shielding the cervical region. Accordingly, the act was limited to a glandular biopsy. The newborn was healthy. Histological examination confirmed the diagnosis of Burkitt's lymphoma. Given the poor general condition of the patient, chemotherapy was not administered and the patient died after 15 days of stay in intensive care unit.

Rhino-orbital cerebral mucormycosis in a child with type 1 diabetes: A case report.

Rhino-orbital cerebral mucormycosis is a rare but potentially severe fungal infection in children with high rate of morbidity and mortality. In pediatric patients, uncontrolled diabetes mellitus is considered to be a predisposing factor only in 15% of cases. To prevent and reduce mortality rate of this severe disease, early diagnosis based on clinical findings and biopsy is highly recommended. Herein, we report a case of rhino-orbital cerebral mucormycosis in a 12-year-old girl with type 1 diabetes to demonstrate that a multimodal management approach, involving early surgery which consists in frequent endoscopic sinus debridement and appropriate antifungal therapy, is essential to effectively reduce the spread of infection and achieve effective outcome.

Severe Calcific Chronic Constrictive Pericarditis as an Unexpected Cause of Death: An Autopsy Case.

Chronic calcific constrictive pericarditis is a rare condition. It can cause severe morbidity and even mortality. The diagnosis may be difficult to establish due to its variable clinical signs. We report an autopsy case of a 54-year-old male with a past medical history of well treated hypertension, diabetes and dyspnea present of 2 weeks, who was discovered dead in his bed. The postmortem examination showed a large band of calcification of the pericardium with obliteration of the pericardial space. Both pericardium and epicardium were thickened with bread-and-butter appearance. Microscopic examination showed thickened pericadium which is formed by a fibrous paucicellular tissue containing extensive basophilic calcifications.
