Regeneration of diabetic axons is enhanced by selective knockdown of the PTEN gene.

Diabetes mellitus renders both widespread and localized irreversible damage to peripheral axons while imposing critical limitations on their ability to regenerate. A major failure of regenerative capacity thereby imposes a 'double hit' in diabetic patients who frequently develop focal neuropathies such as carpal tunnel syndrome in addition to generalized diffuse polyneuropathy. The mechanisms of diabetic neuron regenerative failure have been speculative and few approaches have offered therapeutic opportunities.

Neuromuscular complications of critical illness.

Patients admitted to intensive care units (ICUs) suffer from a wide range of neurological disorders. Some develop within the ICU rendering weakness and difficulty in weaning patients from ventilator support. ICUAW, or ICU acquired weakness, is a broad term that includes several more specific neuromuscular problems.

Ophthalmic manifestations of herpes zoster virus in patients with multiple myeloma following bone marrow transplantation.

We report three patients with ophthalmic herpes zoster (HZ) manifestations on the background diagnosis of multiple myeloma (MM). It seems that immunocompromised status has caused reactivation of the varicella zoster virus (VZV) producing a well-characterised neurological syndrome and subsequent postherpetic neuralgia in two patients. One patient experienced lymphocytic leptomeningitis resulting in unilateral optic neuritis.
