Temporoparietal Resection in a Patient With Landau-Kleffner Syndrome

Landau-Kleffner syndrome (LKS) was originally described by Landau, a neurologist, and Kleffner, a speech pathologist, in 1957 as an epileptic disorder with an acquired aphasia. LKS is a childhood epileptic encephalopathy on the electroclinical spectrum of electrical status epilepticus in sleep (ESES). ESES is an electrographic pattern in which there is significant activation of spike wave discharges throughout slow wave sleep. LKS is an electroclinical syndrome presenting with language regression, seizures, and behavior abnormalities with the electroencephalography (EEG) findings of ESES. Other related syndromes include continuous spike and wave in slow wave sleep (CSWS) and benign childhood epilepsy with centrotemporal spikes (BECTS). In contrast to these other disorders, the primary clinical manifestation of LKS is language regression. Additional clinical findings seen in LKS include attention-deficit disorder, irritability, and autistic-like behaviors. Seizures are present in 70%-80% of children with LKS and typically occur infrequently. The findings on neuroimaging are typically normal in LKS. Although this epileptic encephalopathy resolves spontaneously in adolescence, there is often permanent neurologic sequela, especially if the epilepsy is pharmacoresistant.

This is the first study to comprehensively measure both anatomical and non ‐anatomical OSA traits during sleep in those with COPD + OSA (Overlap syndrome) and compare them to those with OSA alone. No consistent differences were found between the two groups, while worsened lung function did impact upper airway function and control of breathing. These findings have impli cations towards mechanisms underlying OSA, as well as management of sleep apnea. AbstractOverlap syndrome (OVS) is the concurrence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA), and is associated with poor outc...

The malformations of cortical development (most FCD) were the most common pathological type for children cases in China with drug ‐resistant seizures. It was speculated further that the FCD patients with shorter duration of epilepsy before surgery seem to have a higher ratio of being seizure‐free after surgery. AbstractObjectivesThe drug ‐resistant seizures are characterized by frequent and severe onset of seizures in childhood. There is only little literature had extensively explored the types of pathological brain damage in Chinese children cases. The present study aims to investigate the histopathologic findings a...

Authors: Augstburger E, Héron E, Abanou A, Habas C, Baudouin C, Labbe A Abstract Ischemic optic neuropathies are among the leading causes of severe visual acuity loss in people over 50 years of age. They constitute a set of various entities that are clinically, etiologically and therapeutically different. Anatomically, it is necessary to distinguish anterior and posterior forms. From an etiological point of view, the diagnosis of the arteritic form due to giant cell arteritis requires emergent management to prevent blindness and even death in the absence of prompt corticosteroid treatment. When this diagnosi...

CONCLUSIONS: Low topical corticosteroid requirement and sleep disturbance rates in the subjects regularly using moisturizers emphasize the importance of emollient use in treatment. The association of cesarean delivery, history of incubator, and birth in winter with severe disease suggests that disease severity is related to less exposure to environmental allergens in the hygiene hypothesis.

However, less is known about the relationship between AD-related pathology and the behavioural and psychological symptoms of dementia (BPSD) commonly presented by patients. This review discusses the BPSD-like behaviours recapitulated by several mouse models of AD-related pathology, including the APP/PS1, Tg2576...

(Natural News) Pain and insomnia are two pretty common health issues, which is why there is no shortage of medication on the market targeting these conditions. However, individual sleep and pain meds and combination drugs like Tylenol PM come with a host of serious side effects that many people are unwilling to take on. Now,...

ConclusionIn this study, no significant difference was found in spectral analysis and salivary cortisol levels in insomnia patients, but at 18:00 and 24:00, cortisol levels were correlated positively with theta and delta waves in EEG spectral analysis in some channels.

ConclusionsOur data show that SDB, particularly CSA, is common in the acute phase of ULMI and that the frequency of central events decreases in the subacute phase. Further studies are needed to clarify the clinical significance and possible treatment options of SDB in these patients.
