Retention of radiotranslucent foreign bodies in the oesophagus as a cause of stridor

Two infants who presented with stridor were found to have radiotranslucent plastic objects impacted in the oesophagus at the level of the cricoid cartilage. From these 2 cases the lessons to be learnt are that oesophageal foreign bodies retained for even a short period may be a cause of stridor and that when these foreign bodies are not radiographically visible investigation must include the swallowing of contrast medium in which the foreign body should be visible as a translucency.S.

Lymphomatoid granulomatosis A report of 4 cases

Only 1 case of lymphomatoid granulomatosis has previously been reported from South Africa. Experience with 4 such adult patients (2 blacks and 2 whites) is described. These patients were followed up for 15 - 48 months and none developed evidence of a lymphoma during this period. Fever, weight loss, cough and breathlessness were prominent symptoms in all patients. One patient, a black woman, with a diffuse interstitial paUern of lung involvement, had digital clubbing - a rare accompaniment that resolved after therapy. Dilated congestive cardiomyopathy was found in association with pulmonary nodules in a black male patient. All 4 patients were treated with cytotoxic regimens. The 2 patients treated with oral cyclophosphamide and prednisolone responded favourably. The possible explanation for paucity of reports of lymphomatoid granulomatosis from South Africa could be under-reporting, underdiagnosis or a true geographic/ethnic variation in the incidence of this condition

The forward physics facility at the high-luminosity LHC

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments. The proposed Forward Physics Facility (FPF), to be located several hundred meters from the ATLAS interaction point and shielded by concrete and rock, will host a suite of experiments to probe standard model (SM) processes and search for physics beyond the standard model (BSM). In this report, we review the status of the civil engineering plans and the experiments to explore the diverse physics signals that can be uniquely probed in the forward region. FPF experiments will be sensitive to a broad range of BSM physics through searches for new particle scattering or decay signatures and deviations from SM expectations in high statistics analyses with TeV neutrinos in this low-background environment. High statistics neutrino detection will also provide valuable data for fundamental topics in perturbative and non-perturbative QCD and in weak interactions. Experiments at the FPF will enable synergies between forward particle production at the LHC and astroparticle physics to be exploited. We report here on these physics topics, on infrastructure, detector, and simulation studies, and on future directions to realize the FPF's physics potential
