Lafora Body Epilepsy: A Challenging Diagnosis.

Lafora body disease (LBD) is a progressive myoclonic genetic epilepsy syndrome characterized by the presence of Lafora inclusion bodies within neurons and other cells. It is a complex neurodegenerative disease presenting in adolescence with seizures, myoclonus, and rapid cognitive decline. Diagnosis is often challenging requiring a thorough history including family history, identification of Lafora bodies in apocrine sweat glands of axillary skin, and specific DNA sequencing. There is no cure and management is mainly supportive. We present one of the only few cases from Pakistan of LBD based on characteristic biopsy findings, history of similar ailment in siblings, and EPM2B mutation. This case emphasizes the need for physicians and neurologists to be aware of diagnostic challenges associated with LBD and its characteristic findings. Key Words: Lafora body, Progressive epilepsy, Myoclonus, Axillary skin biopsy, EPM2B.

Osmotic nephrosis with mannitol: review article.

Mannitol is commonly used to lower intracranial and intraocular pressures. Large doses/massive infusions of mannitol have been found to be associated with acute renal failure (MI-ARF), that is, osmotic nephrosis. While many researchers have reported individual experiences with this pathology, we felt that there is need of an updated comprehensive review of all reported cases with elaboration of etiology, pathogenesis, diagnosis and management plan for MI-ARF. The purpose of the present communication is to share our own experience with MI-ARF, to review the effect of mannitol on kidney function and to highlight the dynamics of MI-ARF with considerations for the cautious use of mannitol in patients with risk factors for kidney diseases.
