Performances of the IDEIA HpStAR Stool Antigen Test in Detection of Helicobacter pylori Infection Before and After Eradication Treatment in Algerian Children.

We aimed to evaluate in an Algerian pediatric population the diagnostic performances of the IDEIA HpStAR noninvasive stool antigen test (Oxoid, Cambridge, UK) to detect Helicobacter pylori infection before and after eradication therapy. A prospective study including 158 symptomatic Algerian children was conducted. Patients were initially diagnosed with invasive (culture, histology, and rapid urease test) and noninvasive tests (urea breath test and IDEIA HpStAR test). Infected patients were treated, and 101 were controlled after treatment with two invasive (culture and histology) and two noninvasive tests (urea breath test and IDEIA HpStAR test). In Algerian children, the IDEIA HpStAR test showed good performances for initial detection of H. pylori infection and also for subsequent control of eradication treatment. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of IDEIA HpStAR test before treatment were 93.6%, 100%, 100%, 87.3%, and 96%, respectively, and those after treatment were 100, 92.8, 78.6, 100, and 94.2%, respectively.

Feminizing Adrenocortical Carcinoma Without Gynecomastia.

Malignant feminizing adrenocortical tumors are exceedingly rare. Their main presentation is gynecomastia. In these estrogen secreting tumors (with or without other adrenocortical hormones) lack of gynecomastia is exceptional as in our case. A 44-year-old man presented with abdominal pain. Radiological assessment revealed a tumor measuring 120 × 95 mm in the retroperitoneal area with numerous metastases. Pathological examination pleaded for an adrenal origin with a Weiss's score of 5. Six months later, the tumor relapsed, and he had a second surgery and was sent for hormone assessment. Clinical examination showed a skinny man with severe fatigue. He had no Cushingoid features. Gynecomastia and galactorrhea were absent. Penile length, testicular volume, and body hair growth were normal. Several cutaneous nodules were present. Biological assessment showed high morning plasma cortisol, which failed to be suppressed by treatment with 2 mg dexamethasone. Plasma estradiol and 17OH progesterone levels were high, but his testosterone levels were low. Radiological exploration showed numerous metastases: pleural, pulmonary, retroperitoneal, and abdominal. He was treated with classical chemotherapy, but he died four months after diagnosis.
