Actinomyces turicensis: An unusual cause of cervicofacial actinomycosis presenting as ludwig angina in an immunocompromised host - Case report and literature review.

Actinomyces is an anaerobic, gram-positive bacillus that is known to cause chronic granulomatous infections. Common risk factors predisposing patients to this life-threatening infection are recent dental procedures, immunosuppression from malignancy, or history of smoking and alcohol use. Actinomyces, commonly found in the normal flora of the oral cavity, is one of the pathogens that can cause Ludwig's angina.

Delftia acidovorans: A rare cause of septic pulmonary embolism from catheter-related infection: Case report and literature review.

Septic pulmonary emboli is a rare condition due to the dislodgement of an infected thrombus traveling to the pulmonary vasculature via the venous system. Staphylococcus spp. and Candida spp.

Leukocyte kinetics in patients with peritonitis on long-term peritoneal dialysis.

Dialysate and blood leukocyte counts were measured during 130 episodes of peritonitis in 91 hospitalized patients on long-term peritoneal dialysis (CPD). The authors found that the blood/dialysate leukocyte count can be less than 1.0, and this is usually the case when dialysate leukocyte count exceeds 20,000/mm3.

Hyperbaric oxygen therapy in calciphylaxis-induced skin necrosis in a peritoneal dialysis patient.

A 58-year-old white woman on continuous ambulatory peritoneal dialysis for 2 years developed calciphylaxis-induced necrotic skin lesions over both lower extremities. Despite subtotal parathyroidectomy and other conventional measures, skin lesions continued to worsen. Mapping of transcutaneous oxygen pressure showed markedly low values in involved areas.

Primary antiphospholipid antibody syndrome and microscopic polyarteritis in the puerperium: a case report.

The primary antiphospholipid antibody syndrome (PAPS) and systemic lupus erythematosus (SLE) may occur in women of reproductive age, and both syndromes have been reported to exacerbate during periods of hormonal flux such as oral contraceptive administration, pregnancy, or the puerperium. These disorders have features which cause them to resemble other multisystem diseases. PAPS and SLE must be differentiated from preeclampsia with HELLP syndrome and thrombotic thrombocytopenic purpura occurring during pregnancy.
