Epileptic encephalopathies account for a large proportion of the intractable early-onset epilepsies and are characterized by frequent seizures and poor developmental outcome. The epileptic encephalopathies can be loosely divided into two related groups of named syndromes. The first comprises epilepsies where continuous EEG changes directly result in cognitive and developmental dysfunction. The second includes patients where cognitive impairment is present at seizure onset and is due to the underlying etiology but the epileptic activity may then worsen the cognitive abilities over time...

A 65-year-old male originally had surgery for spondylolisthesis at L5-S1 in 2008 and then went on to have an L4-5 transforaminal lumbar interbody fusion (TLIF) with pedicle screw fixation from L4 to S1 and interbody graft in 2010. Despite having two surgical procedures, he continued with intractable back pain and was told he had a failed lumbar fusion. When he was evaluated with a computerized tomography (CT) scan from April 2015, it demonstrated an erosive nonunion of the L4-5 interbody fusion without incorporation of the polyetheretherketone (PEEK) cage...

In this paper we describe a simple and very fast method of data acquisition, feature extraction and feature space creation for epileptic seizure detection. The scalp electroencephalogram (EEG) dataset [1, 2] collected at the Children's Hospital Boston from 22 pediatric patients having 192 intractable seizures (available as CHB-MIT database) is used to assess this simple approach against existing ones [1, 3], with very positive results reaching up to 99.48% Sensitivity.

Oral mucositis is a common and often debilitating complication among cancer patients receiving radiation therapy to the head and neck or chemotherapy agents, or undergoing hematopoietic stem cell transplantation. Pain and decreased oral function associated with oral mucositis may persist long after the conclusion of therapy. Although most patients respond to conservative management, a subset of patients develop intractable pain with severe consequences. For some, the use of total parenteral nutrition with insertion of percutaneous endoscopic gastrostomy feeding tubes is the only alternative...

Endoscopy plays an important role in the diagnosis and treatment of postoperative complications of gastric cancer. Endoscopic intervention can avoid the second operation and has attracted wide attention. Early gastric anastomotic bleeding after gastrectomy is the most common. With the development of technology, emergency endoscopy and endoscopic hemostasis provide a new treatment approach. According to the specific circumstances, endoscopists can choose metal clamp to stop bleeding, electrocoagulation hemostasis, local injection of epinephrine or sclerotherapy agents, and spraying specific hemostatic agents...

BACKGROUND: Opioid use, abuse, and adverse consequences, including death, have escalated at an alarming rate since the 1990s. In an attempt to control opioid abuse, numerous regulations and guidelines for responsible opioid prescribing have been developed by various organizations. However, the US opioid epidemic is continuing and drug dose deaths tripled during 1999 to 2015. Recent data show a continuing increase in deaths due to natural and semisynthetic opioids, a decline in methadone deaths, and an explosive increase in the rates of deaths involving other opioids, specifically heroin and illicit synthetic fentanyl...

OBJECTIVE: Cortico-cortical evoked potential (CCEP) has been utilized to evaluate connectivity between cortices. However, previous reports have rarely referred to the impact of volume-conducted potential (VCP) which must be a confounding factor of large potential around the stimulation site. To address this issue, we challenged the null hypothesis that VCP accounts for the majority of the recorded potential, particularly around the stimulation site. METHODS: CCEP was recorded with high-density intracranial electrodes in 8 patients with intractable epilepsy...

OBJECTIVE: Brain hypothermia controls epileptic discharge and reduces extracellular concentrations of glutamate (Glu), an excitatory neurotransmitter. We aimed to determine the effects of focal brain cooling (FBC) on levels of γ-aminobutyric acid (GABA), which is a major inhibitory neurotransmitter. The relationship between Glu or GABA concentrations and the severity of epileptic symptoms was also analyzed. METHODS: Patients with intractable epilepsy underwent FBC at lesionectomized (n = 11) or hippocampectomized (n = 8) regions at 15°C for 30 min using custom-made cooling devices...

Using an improved, chromatography-free dipyrrin synthesis, the α,β-unsubstituted dipyrrins [RC(C4H2N)2H] (2) (R = tolyl (2toly(l)), p-OMe-C6H4 (2anis), mesityl (2mes), ferrocenyl (2Fc)) were isolated in good to excellent yields. Deprotonation of 2 with Na[N(SiMe3)2] gives the alkali metal salts [Na(DME)n][RC(C4H2N)2] (3) which reacts with UO2Cl2(THF)3 to give the uranyl bis(dipyrrinates) UO2[RC(C4H2N)2]2(L) (L = THF (4R-THF); DMAP (4R-DMAP)) (R = tolyl, p-OMe-C6H4, mesityl, ferrocenyl). The THF adducts, 4R-THF, are unstable in aromatic and nonpolar solvents and rapidly decompose to 2 and an intractable uranium-containing solid...

Advanced glycation end products (AGEs) and their receptor have been implicated in the progressions of many intractable diseases, such as diabetes and atherosclerosis, and are also critical for pathologic changes in chronic degenerative diseases, such as Alzheimer's disease, Parkinson's disease, and alcoholic brain damage. Recently activated macrophages were found to be a source of AGEs, and the most abundant form of AGEs, AGE-albumin excreted by macrophages has been implicated in these diseases and to act through common pathways...

Supportive care and pharmacological treatment can improve the quality of life of people with end-stage chronic obstructive pulmonary disease (COPD) who cope on a daily basis with substantial physical, psychological, social and spiritual morbidity. Smoking cessation is the only intervention that reduces the rate of progression of COPD, but evidence-based drug treatments and non-pharmacological strategies can relieve symptoms and reduce the impact of exacerbations. People with severe COPD live with increasingly troublesome breathlessness and other symptoms such as fatigue, pain, sputum production and weight loss...

Focal cortical dysplasia (FCD) is a major cause of the sporadic form of intractable focal epilepsies that require surgical treatment. It has recently been reported that brain somatic mutations in MTOR account for 15%-25% of FCD type II (FCDII), characterized by cortical dyslamination and dysmorphic neurons. However, the genetic etiologies of FCDII-affected individuals who lack the MTOR mutation remain unclear. Here, we performed deep hybrid capture and amplicon sequencing (read depth of 100×-20,012×) of five important mTOR pathway genes-PIK3CA, PIK3R2, AKT3, TSC1, and TSC2-by using paired brain and saliva samples from 40 FCDII individuals negative for MTOR mutations...

Like asthma and atopic dermatitis, allergic rhinitis is an allergic disease, but of the three, it is the only type I allergic disease. Allergic rhinitis includes pollinosis, which is intractable and reduces quality of life (QOL) when it becomes severe. A guideline is needed to understand allergic rhinitis and to use this knowledge to develop a treatment plan. In Japan, the first guideline was prepared after a symposium held by the Japanese Society of Allergology in 1993. The current 8th edition was published in 2016, and is widely used today...

In 2013, a guideline for occupational allergic diseases was published for the first time in Japan. Occupational allergic diseases are likely to worsen or become intractable as a result of continuous exposure to high concentrations of causative antigens, and are socioeconomically important diseases with which the patients might sometimes lose jobs due to work interruptions. Guidelines for occupational allergic diseases have been published in many countries. This guideline consists of six chapters about occupational asthma, occupational allergic rhinitis, occupational skin diseases, hypersensitivity pneumonitis and occupational anaphylaxis shock, and legal aspects of these diseases...

Pioneer transcription factors (TFs) function as genomic first responders, binding to inaccessible regions of chromatin to promote enhancer formation. The mechanism by which pioneer TFs gain access to chromatin remains an important unanswered question. Here we show that PARP-1, a nucleosome-binding protein, cooperates with intrinsic properties of the pioneer TF Sox2 to facilitate its binding to intractable genomic loci in embryonic stem cells. These actions of PARP-1 occur independently of its poly(ADP-ribosyl) transferase activity...

Non-healing diabetic wounds are difficult to treat. They also create heavy financial burdens for both patients and society. Negative pressure wound therapy (NPWT) has been adopted to treat intractable wounds and has proved to be effective. However, the mechanisms that underlie the effects of this treatment are not entirely understood. Circulating fibrocytes are unique haematopoietic-derived stem cells that have been reported to play a pivotal role in wound healing. Here, we have investigated the effect of NPWT on fibrocyte mobilization and the role of fibrocyte mobilization in the healing of diabetic wounds during NPWT...

BACKGROUND: Electrocorticogram (ECoG) spike activity is enhanced under general anesthesia with 1.5 minimum alveolar concentration (MAC) sevoflurane compared with lower concentrations in adult patients with epilepsy. However, the effect of concentration of sevoflurane on ECoG in children with epilepsy is less known. AIMS: The primary endpoint was to investigate the effects of sevoflurane on ECoG spike activity in pediatric patients undergoing epilepsy surgery. The secondary endpoint was to examine its effects on baseline ECoG including burst suppression...
