Lingual hematoma (LH) is an uncommon and potentially life-threatening condition due to its tendency to cause upper airway obstruction. It usually occurs as a result of trauma (motor vehicle accidents, grand mal seizures or traumatic tracheal intubations) and rarely spontaneously in cases of patients with inherited or acquired coagulopathies, high blood pressure, hematological disorders, or vascular malformations. Herein, we report the first case, to our knowledge, of a traumatic massive lingual hematoma in a patient with Systemic lupus erythematosus (SLE) secondary to tongue biting after neurological deterioration, hypertensive crisis and multiple tonic clonic seizures during hemodialysis for chronic renal failure.

Several antibiotics have been implicated in oral contraception failure when they are administered at the same time as the oral contraceptive (OC) pill. In the present paper, a study about amoxicillin-ethinylestradiol (EE2) pharmacokinetic potential interaction was studied. Two rabbit groups were utilized, the first group received amoxicillin (10 mg/kg) and EE2 (30, 50 and 100 micrograms/kg, respectively), both by intravenous (i.v.) route. The second group received amoxicillin (oral route, 10 mg/kg/day) and EE2 (i.v. route, 100 mu/kg) on day 1, 4 and 8 of antibiotic treatment, respectively. After compartmental (two-compartment open model) and non-compartmental analysis of plasma concentrations, the statistical study (ANOVA p < or = 0.05) revealed that the presence of amoxicillin did not modify the EE2 distribution and elimination pharmacokinetic parameters (by comparison with those obtained in a previous study where EE2 was administered alone). There also were no significant differences with the time of amoxicillin oral treatment.
