In a rabbit study, hydroquinone at 150 mg kg day produced minimal developmental alterations in the presence of maternal toxicity. The no-observed-effect level for developmental toxicity was 75mgkg day In rat studies, maternal toxic effects from exposure to hydroquinone included changes in the ovaries, fallopian tubes, and menstrual cycle. Postimplantation mortality was also observed in rat studies. Observed paternal toxic effects from exposure to hydroquinone included changes in the testes, epididymis, sperm duct, prostate, seminal vesicle, Cowper s gland, accessory glands, and male fertility index. Further, exposure to hydroquinone produced skeletal malformations in chickens and ocular and skeletal malformations in rabbits. Hydroquinone can induce renal tubule adenomas, bladder carcinomas, hepatocellular neoplasms, and mononuclear cell leukemia in experimental animals. 

Active internal bleeding, history of CVA, recent intracranial or intraspinal surgery or trauma, intracranial neoplasm, arteriovenous malformation or aneurysm, bleeding diathesis or severe uncontrolled hypertension (increases risk of bleeding)... 

Cerebritis is focal inflammation of brain parenchyma myelitis in the spinal cord). Cerebritis precedes abscess formation but requires an early biopsy to be seen (see Tables 20.2 and 20.10). The inflammatory infiltrate is composed of neutrophils, macrophages, lymphocytes, and plasma cells, with or without parenchymal necrosis. Septic cerebritis is usually caused by bacterial agents, most often streptococci or staphylococci, and less commonly by gram-negative organisms, such as Escherichia coli. Pseudomonas, and Haemophilus influenzae. Cerebritis also occurs around neoplasms, ruptured vascular malformations, infarcts, and traumatic lesions. 

The exact nature of pontine lesions classified as capillary malformations will remain speculative in the vast majority of patients. Beside vascular malformations, the differential diagnosis of an enhancing pontine lesion might include neoplasm, demyelin-ating disease, infection, infarction, or, rarely, central pontine myelinolysis. The absence of mass effect or significant T2 prolongation, however, argues... 

Defects of the head and face may be the result of removal of a neoplasm, a trauma such as a traffic accident or a gunshot, or also fire [1, 2], They may also appear congenitally as micro and/or anotia [3], Either acquired or congenital defects, malformations or deformities of the face eventually lead to heavy psychosocial hazards requiring rehabilitation. The complex aesthetic units of the nose, ears, eyes and the neighboring regions are predominant [1],...
