ABSTRACT
Clinicians are sometimes confronted with the diagnostic difficulties of the idiopathic form of Castleman's Disease (iMCD). As this review reports with demonstrative clinical cases, iMCD can mimic various serious systemic pathologies such as certain autoimmune diseases, Still's disease, POEMS syndrome, and malignant lymphoproliferations, sharing a very similar histology and identical symptoms. To make a diagnosis of iMCD, the clinician must eliminate all the pathologies mentioned above, but he must first think of it and evoke this diagnosis of rare disease before the first symptoms but also know how to evoke this diagnosis again even after several years of evolution of a disease like those mentioned above whose evolution is not favorable. © 2022 Published by Elsevier Masson SAS on behalf of Société nationale française de médecine interne (SNFMI).

INTRODUCTION: Thoracic endometriosis (TE) is a rare disorder affecting women during their reproductive years. Manifestations of TE include pneumothorax and haemothorax. Treatment is based on surgical and hormonal therapy that aims at eradicating existing endometrial thoracic plaques and to prevent reseeding from pelvic endometriosis. CASE REPORT: We report the case of a 36 year-old young woman presenting thoracic endometriosis revealed by a recurring spontaneous, large and isolated right haemothorax. Diagnosis, pathogeny and treatment are discussed. CONCLUSION: Thoracic endometriosis needs to be considered as a cause of haemothorax in women of childbearing age.

There is as yet no consensus on the treatment of cerebral venous thrombosis (CVT) in Behçet's disease, and the place of anticoagulation is also still being debated. This report is of a series of seven patients with Behçet's disease (BD)-associated CVT, for which anticoagulation was stopped, and discusses the possibility of stopping anticoagulation during follow-up while receiving optimal treatment for BD. The diagnosis of BD was established during follow-up, which lasted a median of 120 [range: 60-1490] days after CVT diagnosis. The median duration of anticoagulation therapy was 29.5 months. On stopping anticoagulation, concomitant treatment then included colchicine, steroids and azathioprine, all introduced after BD was diagnosed. With a median follow-up of 25 months after anticoagulation interruption, only one relapse of CVT was observed. No relapse of CVT or other venous thrombosis was observed in the six patients treated by steroids associated with an immunosuppressant or colchicine. Our results emphasize that corticosteroids are essential for the treatment of BD-associated CVT, and that anticoagulant therapy may be safely stopped during follow-up in the presence of optimal BD treatment (steroids alone or with immunosuppressive drugs).

Yam (Dioscorea spp) is an essential tuber crop for hundreds of millions of people in many African, Asian and South American countries. Considering in particular Southwest Nigeria, chips, flakes and flours are amongst the most common shelf-stable traditionally-processed yam products. This paper reports a systematic study on the proximate (moisture, protein, carbohydrate, fibre, fat, ash and gross energy) and mineral composition of these three food commodities sold in Nigerian markets. Results showed no significant differences in the moisture, crude protein and fibre content of all samples (10.0-12.3, 2.7-4.3 and 1.3-2.0 wt%, respectively). Gross energy was also comparable for all yam derived food items (between 3300 and 3507 kcal/kg), contradicting the common belief that yam flakes have lower nutritional value than chips and flours. Considering the mineral composition, Ca, Mg, P and K were the predominant macronutrients. Micronutrients such as Zn, Co, Mn and Cu were also detected. Significant differences existed between products, and their various sources (markets). Principal component analysis showed a direct correlation between ash content of the samples and the assessed macronutrients, irrespective of the market, or the seller of the commodities. This study confirmed that yam derived food stuffs have an adequate nutritional composition, irrespective of their form and/or origin.

INTRODUCTION: We report an unusual observation of central nervous system (CNS) lymphoma in a 60-year-old woman with systemic lupus erythematosus and fatal outcome. OBSERVATION: The patient had systemic erythematosus lupus for 7 years, treated with mycophenolate mofetil and developed lymphocytic meningitis in 2015 associated to the presence of EBV in the cerebrospinal fluid and a necrotic vermis' lesion. Diagnosis of large B-cell lymphoma was histologically confirmed from stereotaxic biopsy, shortly before she died from neurological complications. CONCLUSION: Even though the current association is unusual, lymphocytic meningitis with hypoglycorrachia in patients with systemic lupus erythematosus may reveal CNS lymphoma and diagnosis confirmation requires stereotaxic biopsy in order not to delay specific therapeutic management.

Biofilm-associated bacteria display a decreased susceptibility towards antibiotics. Routine assessment of antibiotic susceptibility of planktonic bacteria therefore offers an insufficient prediction of the biofilm response. In this study, in vitro biofilms of eight clinical Staphylococcus epidermidis strains were subjected to treatment with vancomycin, teicoplanin, oxacillin, rifampicin and gentamicin. In addition, the biofilms were subjected to combinations of an antibiotic with rifampicin. The effects on the biofilms were assessed by crystal violet staining to determine the total biofilm biomass, staining with XTT to determine bacterial cell viability, and microscopy. Combining these methods showed that treatment of S. epidermidis biofilms with glycopeptides increased the total biofilm biomass and that these antibiotics were not effective in killing bacteria embedded in biofilms. The decreased killing efficacy was more pronounced in biofilms produced by strains that were classified as 'strong' biofilm producers. Rifampicin, oxacillin and gentamicin effectively killed biofilm-associated bacteria of all tested strains. Combining antibiotics with rifampicin increased the killing efficacy without influencing the total biofilm biomass. When vancomycin or teicoplanin were combined with rifampicin, the increase in biofilm biomass was neutralised and also the killing efficacy was influenced in a positive way. We conclude that the combined methodology used in this study showed that glycopeptides were not effective in eradicating S. epidermidis biofilms but that combination with rifampicin improved the killing efficacy in vitro.

BACKGROUND: Mucormycosis are rare fungal infections occurring chiefly in the lung or the rhinocerebral compartment, particularly in patients with immunodeficiency or mellitus diabetes. We report the case of an elderly patient with cutaneous mucormycosis caused by Rhizopus microsporus. PATIENTS AND METHODS: An 89-year-old man presented a skin lesion of the forearm rapidly becoming inflammatory and necrotic. The patient had been treated for 2months with oral corticosteroids for idiopathic thrombocytopenia. Histological and mycological examination of the skin biopsy revealed the presence of a filamentous fungus, R. microsporus. The outcome was unfavorable, despite prescription of high-dose liposomal amphotericin B. DISCUSSION: Mucormycosis are infrequent opportunistic infections caused by angio-invasive fungi belonging to the Mucorales order. Cutaneous presentations are rare, and in rare cases the species R. microsporus is isolated in clinical samples. Diagnosis is based on histological examination highlighting the characteristic mycelium within infected tissue, together with ex vivo mycological identification using morphological and molecular methods. Treatment consists of liposomal amphotericin B combined with debridement surgery. CONCLUSION: R. microsporus is a marginal fungal species rarely isolated in clinical practice, and even less in dermatology departments. This clinical case report highlights the severity of infection with this fungus, particularly in the absence of early surgery.

In order to correlate gross morphological features with pulmonary and coronary vasculature changes in hypoplastic left heart syndrome (HLHS) 15 heart-lung necropsy specimens from neonates were analysed. Histology of left atrium wall, lung vessels with pulmonary arteriolar disease morphometric grading, study of intra and extra pulmonary wall veins and coronary arteries were recorded. Classic HLHS was observed in 11, and DORV with mitral atresia in 4, the foramen ovale (FO) being the only left atrium outflow tract in all. All specimens had increased % of thickness and muscular extension of arterioles and increased wall thickness of pulmonary veins, but severer arteriolar and venous changes with left atrium fibrosis were noticed in 8 specimens with either closed FO (3 cases) or mean FO diameter (d) of 5 mm when compared with specimens with mean FOd of 9 mm. Coronary arteries histology disclosed in 4 of 8 specimens with opened but hypoplastic mitral valve, intima proliferative changes with lumen narrowing, not observed in 7 specimens with mitral valve atresia. We concluded that in HLHS closed or restrictive FO and permeable mitral valve may predispose neonates to respiratory complications, right ventricle abnormal function and arrhythmias, specially after cardiac surgery.

The authors describe a perplexing clinical picture in which an important factor for diagnosing the lesion in the gall-bladder was hyperselective arteriography of the coeliac trunk, and more especially the hepatic artery. The association of a truc septum in the gall-bladder, without gall-stones, and of another digestive tube lesion, megadolicho-sigmoid and diverticulosis of the sigmoid, would appear to be an extremely rare entity, and this has been the cause of the pain reported by the patient over many years. The cholecystectomy performed appears to be the right choice, and the most effective therapeutic procedure.
