[Evaluation of coagulopathies and fibrinolytic abnormalities in central retinal vein occlusion in patients under 60 years of age].

Purpose: To investigate the association of thrombophilic and fibrinolytic factors with central retinal vein occlusion (CRVO) in patients under 60 years of age.

Materials And Methods: A prospective, observational study of 21 patients with CRVO compared with an age- and sex-matched control group of 23 volunteers was performed. All participants were tested for: cholesterol, hypertension, factors VIII, IX, and XI, homocysteine, antiphospholipid antibodies, antithrombin III, proteins C and S, protein Z and protein Z antibodies, resistance to activated protein C, factor V Leiden mutation, prothrombin mutation, MTHFR genotypes, plasminogen activator inhibitor-1 (PAI-1) and tissue plasminogen activator (t-PA) polymorphisms.

[Orbitotemporal segmental neurofibromatosis].

Introduction: Neurofibromatosis is a rare pathology with heterogeneous clinical presentation.

Observation: We report a case of a right orbitotemporal plexiform neurofibroma in a 64-year-old woman with von Recklinghausen's neurofibromatosis. A craniofacial CT scan, with injection, showed a heterogeneous tumor in front of the skull base and the temporoparietal bone with no intracranial extension but an extension into the maxillary sinus and nasal cavity.

Elderly haematological patients with chemotherapy-induced febrile neutropenia have similar rates of infection and outcome to younger adults: a prospective study of risk-adapted therapy.

We prospectively evaluated 131 consecutive episodes of fever and chemotherapy-induced neutropenia in 85 adults with haematological malignancies to determine whether older patients (aged < 60 years) have different causes of fever and outcome than younger adults (aged < 60 years). Patients were stratified into high-risk and low-risk groups according to previously published criteria. High-risk patients received ceftazidime plus amikacin and low-risk patients received ceftazidime alone.

Spontaneous gas gangrene in malignant lymphoma: an underreported complication?

We report a case of spontaneous gas gangrene (SGG), the most rapidly progressive form of clostridial infection, in a patient with non-Hodgkin's lymphoma (NHL). We review the literature and examine the association between these two entities. A 43-year-old man with NHL developed fatal C.
