Emergence of Long-Range Angular Correlations in Low-Multiplicity Proton-Proton Collisions

This Letter presents the measurement of near-side associated per-trigger yields, denoted ridge yields, from the analysis of angular correlations of charged hadrons in proton-proton collisions at sqrt[s]=13  TeV. Long-range ridge yields are extracted for pairs of charged particles with a pseudorapidity difference of 1.4<|Δη|<1.8 and a transverse momentum of 1 Collapse

[A malignant schwannoma of the jejunum associated with multiple neurofibromas and a primary adenoma of the parathyroid]

A case of schwannosarcoma associated with a pleural neurofibroma and a parathyroid adenoma is presented. The neuroectodermal origin and the relationship with neurofibromatosis are discussed. The sarcomatous relapse of a schwannoma previously classified as benign confirms the difficulty of microscopic analysis and the malignancy power of the tumor. A long survival is obtained by a large intestinal and mesenteric resection as long as hepatic metastases are not present or can be resected. The pleural neurofibroma needs symptomatic treatment while parathyroid adenoma must be early removed as soon as malignant hypercalcemia is detected.

[A case of peritonitis due to perforation of the small intestines of tubercular etiology. Review of the literature]

The perforation into free peritoneum is a singular complication of the intestinal tuberculosis. Regarding a recent observation of this complication revealing small intestinal tuberculosis, we have tried to make the point on this exceptional form of small intestinal tuberculosis. By means of prolonged enteric nutrition and antitubercular treatment, the patient will be cured of this disease without any after-effects as we mentioned it in our observation. Very fearsome in the past (44 deaths out of 104 published cases), perforation into free peritoneum nowadays has a better prognosis.
