BACKGROUND: Prevalence of lower urinary tract dysfunction (LUTD) in children is between 6 and 9% with urinary incontinence (UI) being one of the most common symptom. VARIOUS ASPECTS OF LOWER URINARY TRACT SYMPTOMS LUTS: Anatomical anomalies of the urinary tract as well as neurogenic underlying pathology can results in LUTS. Comorbidities and long-term consequences of the LUTD for the female patients as well as genetic issues are also briefly discussed. THE ROLE OF THE BLADDER NECK: Thanks to urodynamics, we have learnt a lot about the lower urinary tract function, but the role of the bladder neck in the pathophysiology of LUTS in children is not clear...

BACKGROUND: Fibroblast growth factors (FGFs) and their receptors (FGFRs) have numerous functions in the developing and adult central nervous system (CNS). For example, the FGFR1 receptor is important for proliferation and fate specification of radial glial cells in the cortex and hippocampus, oligodendrocyte proliferation and regeneration, midline glia morphology and soma translocation, Bergmann glia morphology, and cerebellar morphogenesis. In addition, FGFR1 signaling in astrocytes is required for postnatal maturation of interneurons expressing parvalbumin (PV)...

Recent reports show that, in patients treated with finasteride for male pattern hair loss, persistent side effects including sexual side effects, depression, anxiety and cognitive complaints may occur. We here explored the psychiatric and andrological features of patients affected by post-finasteride syndrome (PFS) and verified whether the cerebrospinal fluid (CSF) and plasma levels of neuroactive steroids (i.e., important regulators of nervous function) are modified. We found that eight out of sixteen PFS male patients considered suffered from a DSM-IV major depressive disorder (MDD)...

Adipose tissue-derived stem cells (ASCs) can be obtained from different adipose tissue sources within the body. It is an abundant cell pool, easily accessible, suitable for cultivation and expansion in vitro and preparation for therapeutic approaches. Amongst these therapeutic approaches are tissue engineering and nervous system disorders such as spinal cord injuries. For such treatment, ASCs have to be reliably differentiated in to the neuronal direction. Therefore, we investigated the neural differentiation potential of ASCs using protocols with neurogenic inductors such as valproic acid and forskolin, while dog brain tissue served as control...

Functional fecal incontinence (FFI) is divided into cases related to functional constipation (FC) and cases without concomitant constipation termed functional non-retentive fecal incontinence (FNRFI). Transanal irrigation (TAI) is widely used in children with neurogenic fecal incontinence but is less studied in children with functional defecation disorders. The aim was to evaluate the feasibility and efficacy of TAI in the treatment of FFI. A retrospective study in 72 children (mean age 9.2 ± 2.2 years, 47 males) with treatment-resistant FFI was performed...

Background Many patients with mid-face or lower face craniofacial pain are diagnosed, based on accompanying signs and symptoms and features other than location, as either atypical migraines or atypical TACs. Distinguishing features of headache disorders as a cause of facial pain include the temporal pattern of pain, associated symptoms including light and sound sensitivity and nausea, cranial autonomic symptoms, and the lack of local triggering among others. Results An intraoral neurovascular pain has been observed, and was termed neurovascular orofacial pain (NVOP)...

Parkinson's disease (PD) is a neurogenerative disease, which causes motoric disorders, and the risk of developing PD increases with age. There is an increasing number of persons above 60 years undergoing anaesthesia, and PD is becoming a common comorbidity. PD symptoms, delayed medicine administration or medical side effects can complicate anaesthesia. The importance of correct administration of PD medication administration must be emphasized to avoid complications. Optimized perioperative care can potentially prevent complicated and prolonged admission periods...

Visceral hypersensitivity is an important mechanism underlying increased abdominal pain perception in functional gastrointestinal disorders (FGID) including functional dyspepsia, irritable bowel syndrome (IBS) and inflammatory bowel disease in remission. Although the exact pathophysiological mechanisms are poorly understood, recent studies described upregulation and altered functions of nociceptors and their signaling pathways in aberrant visceral nociception, in particular the transient receptor potential (TRP) channel family...

Recent studies have uncovered evidence suggesting that interference with hippocampal adult neurogenesis contributes to neurodegeneration in Alzheimer's disease (AD). Evidence supporting that AD is a metabolic disease with derangements in brain glucose utilization implies the use of anti-diabetics as an alternate therapeutic strategy. The present study drew comparison between the pro-neurogenic potential of metformin and donepezil in AlCl3-induced mouse model of neurodegeneration. Morris water maze task and subsequent immunohistochemical evaluation for NeuN was conducted...

PURPOSE OF REVIEW: Lower urinary tract and sexual dysfunction are commonly reported sequelae of neurologic disease and have a significant impact on quality of life. This article presents an up-to-date summary of the clinical presentation, investigations, and treatment options for urogenital dysfunction in patients with neurologic disease. RECENT FINDINGS: The pattern of lower urinary tract dysfunction is influenced by the site of the neurologic lesion. The risk for developing upper urinary tract damage is considerably less in patients with slowly progressive nontraumatic neurologic disorders, as compared to those with spinal cord injury or spina bifida...

Cutaneous neurogenic inflammation (CNI) is inflammation that is induced (or enhanced) in the skin by the release of neuropeptides from sensory nerve endings. Clinical manifestations are mainly sensory and vascular disorders such as pruritus and erythema. Transient receptor potential vanilloid 1 and ankyrin 1 (TRPV1 and TRPA1, respectively) are non-selective cation channels known to specifically participate in pain and CNI. Both TRPV1 and TRPA1 are co-expressed in a large subset of sensory nerves, where they integrate numerous noxious stimuli...

BACKGROUND & AIMS: Neural stem and progenitor cells from the enteric nervous system (ENS) might serve as a source of cells for treatment of neurogastrointestinal disorders. Before we can use these cells, we must increase our understanding of the signaling mechanisms that regulate proliferation and differentiation. We systematically evaluated the effects of canonical Wnt signaling on proliferation and differentiation of cultured ENS progenitor cells from neonatal mice and humans. METHODS: We isolated ENS progenitors from tunica muscularis of the small intestine of new-born (P0) wild-type C57BL/6 mice as well as from Wnt1-Cre2 reporter mice...

Waardenburg syndrome (WS) is an autosomal dominant inherited neurogenic disorder with the combination of various degrees of sensorineural deafness and pigmentary abnormalities affecting the skin, hair and eye. The four subtypes of WS were defined on the basis of the presence or absence of additional symptoms. Mutation of human microphthalmia-associated transcription factor (MITF) gene gives rise to WS2. Here, we identified a novel WS-associated mutation at the stop codon of MITF (p.X420Y) in a Chinese WS2 patient...

The neuropeptide substance P (SP) is an important mediator of neurogenic inflammation within the central and peripheral nervous systems. SP has been shown to induce the expression of pro-inflammatory cytokines implicated in the pathogenesis of several disorders of the human brain via the neurokinin-1 receptor (NK-1R). Ketamine, an intravenous anesthetic agent, functions as a competitive antagonist of the excitatory neurotransmission N-methyl-D‑aspartate (NMDA) receptor, and also antagonizes the NK-1R by interfering with the binding of SP...

ZC4H2 is involved in human brain development, and, if mutated, can be responsible for a rare X-linked disorder, originally presented in literature as Wieacker-Wolff syndrome and Miles-Carpenter syndrome. In males, severe intellectual disability is associated with variable symptoms of central and peripheral nervous system involvement, such as spasticity, hyperreflexia, muscle weakness, and arthrogryposis. Female carriers are usually described as asymptomatic or only mildly affected. Here, we report on a girl carrying a de novo deletion of ZC4H2 detected by array-CGH analysis...

Foreign accent syndrome is a rare motor speech disorder that causes patients to speak their language with a non-native accent. In the neurogenic condition, the disorder develops after lesions in the language dominant hemisphere, often affecting Broca's area, the insula, the supplementary motor area and the primary motor cortex. Here, we present two new cases of FAS after posterior fossa lesions. The first case is a 44-year-old, right-handed, Dutch-speaking man who suffered motor speech disturbances and a left hemiplegia after a pontine infarction...

A major concern associated with ZIKV infection is the increased incidence of microcephaly with frequent calcifications in infants born from infected mothers. To date, postmortem analysis of the central nervous system (CNS) in congenital infection is limited to individual reports or small series. We report a comprehensive neuropathological study in ten newborn babies infected with ZIKV during pregnancy, including the spinal cords and dorsal root ganglia (DRG), and also muscle, pituitaries, eye, systemic organs, and placentas...
