    Full Text Available Conservative therapy is often the first-line treatment for many symptoms of various disease processes, including pain. Nevertheless, if pharmacological or medical management fails for those patients with severe and chronic pain, a surgical strategy may be a reasonable option. First performed for psychiatric disorders, cingulotomy now has been recognized as a viable option for the management of pain. The authors review the literature on anterior cingulotomy for intractable pain to provide guidelines for management and expected outcomes.

    Thalamotomy aiming at the CM-Pf complex and using stereotactic gamma irradiation has been performed in a series of 52 patients with severe pain due to malignancy. Lesions were produced either contra- or ipsilaterally to the side of the pain as well as bilaterally. Eight patients experienced good pain relief, 18 had moderate relief, and in 24 the operation did not significantly influence the pain. A second operation following recurrence of pain was rarely of value. There was a tendency towards more efficient relief of pain located in the face or in the arm and shoulder than of pain in the lower part of the body. Although contralateral lesions seem to be most effective, ipsilateral operations may also give some relief. The best results were obtained when the lesions were placed close to the wall of the third ventricle and at the level of the posterior commissure. Postmortem examination of 21 brains disclosed that the mean error in the placing of the lesions was about 1 mm. It is concluded that medial thalamotomy may be tried as a last resort in the treatment of cancer pain in selected patients with a short life expectancy. (author)

    Full Text Available Pain caused by tumor infiltration of the sacral area remains a major clinical challenge. Patients with poor pain control despite comprehensive medical management may be treated with neuraxial techniques such as continuous epidural or spinal anesthetic. We report a case in which a patient with metastatic breast cancer experienced inadequate pain relief after multiple intravenous pain management regimens as well as intrathecal (IT drug delivery. The concentration of local anesthetics delivered via the IT catheter was limited due to the patient's baseline motor weakness which would be exacerbated with higher concentrations of local anesthetics. Thus, a decision was made to insert an epidural catheter via a retrograde technique to provide the patient with a “band of anesthesia” which would provide profound sensory blockade without concomitant motor weakness. Pain refractory to other modalities of pain control was successfully treated with the epidural technique.

Patients and methods: This case series presents the treatment of three knees in two patients (one bilateral in whom an all-inside arthroscopic medial release and lateral imbrication of the patellar retinaculum was performed. Subjective measurement of pain was the primary outcome measurement, and subjective patellofemoral instability was the secondary outcome measurement. Results: Subjectively the two patients had full resolution of their pain, without any patellofemoral instability. Conclusion: Medial release and lateral imbrication of the patellar retinaculum is a new surgical procedure that has been used in the treatment of intractable patellofemoral pain syndrome. This is the first report of its kind in the literature. While outcome measurements were less than ideal, the patients had positive outcomes, both functionally and in terms of pain.

    2017-08-01

    OBJECTIVE Dorsal root entry zone (DREZ) lesioning has been the most effective surgical treatment for the relief of intractable pain due to root avulsion injury, but residual pain and a decrease in pain relief in the follow-up period have been reported in 23%-70% of patients. Based on pain topography in the most recent studies on neuropathic pain, the authors modified the conventional DREZ lesioning procedure to improve clinical outcomes. The presumed rationale for this procedure is to eliminate the spontaneous discharges of neurons in the superficial spinal dorsal horn as well as wide dynamic range neurons in the deep spinal dorsal horn. METHODS Ten patients with avulsion-related pain underwent surgery between 2011 and 2015. The surgical procedure was described and postoperative pain relief was assessed as follows: excellent (residual pain never exceeded 3 on the visual analog scale [VAS] without medication), good (residual pain never exceeded 5 on the VAS with medication), and poor (residual pain was greater than 5 with medication). Specific perioperative complications were assessed. RESULTS The aim of this surgical procedure was to destroy the deeper layers of the posterior horn of spinal gray matter, which was in contrast to the procedures of Nashold and Sindou, which were to destroy the superficial layers. All patients achieved excellent (n = 7, pain relief without medication) or good (n = 3, pain relief with medication) pain relief postoperatively, and the recurrence of pain was not reported in any patients (median 29 months after surgery, range 12-64 months). Nine patients (90%) achieved complete pain relief (a score of 0 or 1 on the VAS) with or without medication. No surgical site complications such as infection or CSF leakage were noted. No motor deficit was observed in any patient. A sensory deficit was observed in 2 patients and disappeared within 1 month in 1 patient. New pain at the adjacent level of DREZ lesioning was observed in 3 patients and

    A study is reported of the treatment of 21 patients with radioactive iodine over the past 15 years, all of whom had intractable symptoms of dyspnea or exertional chest pain due to heart or pulmonary disease. The evaluation of benefits was subjective, but all patients were followed by one observer. About 60% of the patients received benefit that was worthwhile. Indications for administration of radioactive iodine are: Life expectancy over 3 months, severe angina or dyspnea, lack of response to usual therapeutic measures, spontaneous improvement unlikely, relatively stable symptoms and signs and a cooperative patient and family.

Successful management of severe cancer pain may require invasive treatment. However, a patient's refusal of an invasive procedure necessitates that clinicians consider alternative options. Objective: Intrathecal bupivacaine delivery as a viable treatment of intractable pain is well documented. There are no data on rectal bupivacaine use in cancer patients or in the treatment of cancer tenesmoid pain. This study aims to demonstrate that bupivacaine administered rectally could be a step in between the current treatment options for intractable cancer pain (conventional/conservative analgesia or invasive procedures, and to evaluate the effect of the mode of administration (intrathecal versus rectal on the bupivacaine plasma concentration.Cases: We present two Caucasian, elderly inpatients admitted to hospice due to intractable rectal/tenesmoid pain. The first case is a female with vulvar cancer, and malignant infiltration of the rectum/vagina. Bupivacaine was used intrathecally (0.25–0.5%, 1–2 mL every 6 hours. The second case is a female with ovarian cancer and malignant rectal infiltration. Bupivacaine was adminstered rectally (0.05–0.1%, 100 m

    To use biomarkers to gain insight into and gauge the residual (post-treatment) level of inflammation in two groups of intensively treated patients with severe chronic pain. Three study groups were analyzed, and included: (i) patients (n = 90) with chronic intractable pain (CIP), (ii) patients (n = 26) with chronic pain and MRI-documented arachnoiditis (ARC) and (iii) normal subjects without a diagnosis of chronic pain (n = 86). We determined and compared the serum concentrations of Alpha-1 Antitrypsin (A1AT), Myeloperoxidase (MPO) and soluble Tumor Necrosis Factor receptor type 2 (sTNFR2) in each of the patient populations studied. Patients treated for ARC or CIP had higher serum levels of A1AT and MPO than normal untreated subjects without a diagnosis of chronic pain. ARC patients had an A1AT mean serum concentration of 167.9 ± 41.9 mg/dL as compared to 148.9 ± 35.2 mg/dL for normal subjects (p = 0.023). CIP patients had the highest mean serum A1AT level 183.6 ± 39.2 mg/dL with p values of pain, sites of neuroinflammation elaborate MPO and other inflammatory factors which may not be completely cleared from the system despite extensive and complex treatment regimens.

    We report a case of a 39-year-old man with intractable multifocal pain caused by metastatic urachal carcinoma to the bone. The patient underwent a partial cystectomy in May 2008, and lung metastasis occurred 9 months after the surgery. He then received salvage chemotherapy, but developed metastasis to the liver, brain, and bone. He was hospitalized due to a shoulder pain, a lower back pain, buttocks pain, numbness in both legs, and drop foot in right leg. MRI revealed metastases to the spine, and lumbar spinal canal stenosis with cauda equina compression. Even a combination of fentanyl-patch, oral acetaminophen, gabapentin and paroxetine was not effective for pain control. Strontium-89 therapy and subarachnoid phenol block successfully eliminated intractable pain. The patient could be discharged from hospital and received a palliative care at home for a short period of time. (author)

    There is currently no reliable treatment for phantom limb pain (PLP). Chronic PLP and associated cortical abnormalities may be maintained from abnormal peripheral input, raising the possibility that a continuous peripheral nerve block (CPNB) of extended duration may permanently reorganize cortical pain mapping, thus providing lasting relief. Three men with below-the-knee (2) or -elbow (1) amputations and intractable PLP received femoral/sciatic or infraclavicular perineural catheter(s), respectively. Subjects were randomized in a double-masked fashion to receive perineural ropivacaine (0.5%) or normal saline for over 6 days as outpatients using portable electronic infusion pumps. Four months later, subjects returned for repeated perineural catheter insertion and received an ambulatory infusion with the alternate solution ("crossover"). Subjects were followed for up to 1 year. By chance, all three subjects received saline during their initial infusion and reported little change in their PLP. One subject did not receive crossover treatment, but the remaining two subjects reported complete resolution of their PLP during and immediately following treatment with ropivacaine. One subject experienced no PLP recurrence through the 52-week follow-up period and the other reported mild PLP occurring once each week of just a small fraction of his original pain (pretreatment: continuous PLP rated 10/10; posttreatment: no PLP at baseline with average of one PLP episode each week rated 2/10) for 12 weeks (lost to follow-up thereafter). A prolonged ambulatory CPNB may be a reliable treatment for intractable PLP. The results of this pilot study suggest that a large, randomized clinical trial is warranted. Wiley Periodicals, Inc.

  15. Intractable Chronic Low-Back Pain Caused by Ligamentopathia Treated Using a Spinous Process Plate (S-plate

    Full Text Available We report a case of intractable chronic low-back pain in a gymnast that was caused by ligamentopathia in the interspinous region of the lumbar vertebrae. Sprained interspinous ligaments are a common mechanical cause of acute low-back pain in athletes. Although conservative therapy is generally effective in such cases, in this case it was not. The patient experienced severe low-back pain during lumbar flexion with tension between the L5/S interspinous ligaments. We performed interspinous fixation by using a spinous process plate system, which has been developed for short in situ fusions, and following which the low-back pain resolved. Conservative therapy for low-back pain caused by ligamentopathia is first-line choice, but interspinous fixation with instrumentation might be recommended in intractable cases with conservative therapy.

    Adolescents’ participation in intergroup conflicts comprises an imminent global risk, and understanding its neural underpinnings may open new perspectives. We assessed Jewish-Israeli and Arab-Palestinian adolescents for brain response to the pain of ingroup/outgroup protagonists using magnetoencephalography (MEG), one-on-one positive and conflictual interactions with an outgroup member, attitudes toward the regional conflict, and oxytocin levels. A neural marker of ingroup bias emerged, expressed via alpha modulations in the somatosensory cortex (S1) that characterized an automatic response to the pain of all protagonists followed by rebound/enhancement to ingroup pain only. Adolescents’ hostile social interactions with outgroup members and uncompromising attitudes toward the conflict influenced this neural marker. Furthermore, higher oxytocin levels in the Jewish-Israeli majority and tighter brain-to-brain synchrony among group members in the Arab-Palestinian minority enhanced the neural ingroup bias. Findings suggest that in cases of intractable intergroup conflict, top-down control mechanisms may block the brain’s evolutionary-ancient resonance to outgroup pain, pinpointing adolescents’ interpersonal and sociocognitive processes as potential targets for intervention.

    Despite growing interest in the therapeutic use of cannabis to manage chronic pain, only limited data that address these issues are available. In recent years, a number of nations have introduced specific laws to allow patients to use cannabis preparations to treat a variety of medical conditions. In 2015, the Italian government authorized the use of cannabis to treat several diseases, including chronic pain generally, spasticity in multiple sclerosis, cachexia and anorexia among AIDS and cancer patients, glaucoma, Tourette syndrome, and certain types of epilepsy. We present the first snapshot of the Italian experience with cannabis use for chronic pain over the initial year of its use. This is a retrospective case series analysis of all chronic pain patients treated with oral or vaporized cannabis in six hubs during the initial year following the approval of the new Italian law (December 2015 to November 2016). We evaluated routes of administration, types of cannabis products utilized, dosing, and effectiveness and safety of the treatment. As only one of the six centers has extensively used cannabinoids for intractable chronic pain (614 patients of 659), only the population from Azienda Ospedaliero Universitaria Pisana (Pisa) was considered. Cannabis tea was the primary mode of delivery, and in almost all cases, it was used in association with all the other pain treatments. Initial and follow-up cannabinoid concentrations were found to vary considerably. At initial follow-up, 76.2% of patients continued the treatment, and <15% stopped the treatment due to side effects (none of which were severe). We present the first analysis of Italian clinical practice of the use of cannabinoids for a large variety of chronic pain syndromes. From this initial snapshot, we determined that the treatment seems to be effective and safe, although more data and subsequent trials are needed to better investigate its ideal clinical indication.

    Evaluate the seizure-reduction response and safety of brain-responsive stimulation in adults with medically intractable partial-onset seizures of neocortical origin. Patients with partial seizures of neocortical origin were identified from prospective clinical trials of a brain-responsive neurostimulator (RNS System, NeuroPace). The seizure reduction over years 2-6 postimplantation was calculated by assessing the seizure frequency compared to a preimplantation baseline. Safety was assessed based on reported adverse events. Additional analyses considered safety and seizure reduction according to lobe and functional area (e.g., eloquent cortex) of seizure onset. There were 126 patients with seizures of neocortical onset. The average follow-up was 6.1 implant years. The median percent seizure reduction was 70% in patients with frontal and parietal seizure onsets, 58% in those with temporal neocortical onsets, and 51% in those with multilobar onsets (last observation carried forward [LOCF] analysis). Twenty-six percent of patients experienced at least one seizure-free period of 6 months or longer and 14% experienced at least one seizure-free period of 1 year or longer. Patients with lesions on magnetic resonance imaging (MRI; 77% reduction, LOCF) and those with normal MRI findings (45% reduction, LOCF) benefitted, although the treatment response was more robust in patients with an MRI lesion (p = 0.02, generalized estimating equation [GEE]). There were no differences in the seizure reduction in patients with and without prior epilepsy surgery or vagus nerve stimulation. Stimulation parameters used for treatment did not cause acute or chronic neurologic deficits, even in eloquent cortical areas. The rates of infection (0.017 per patient implant year) and perioperative hemorrhage (0.8%) were not greater than with other neurostimulation devices. Brain-responsive stimulation represents a safe and effective treatment option for patients with medically intractable

    Phenytoin is an anti-convulsant and anti-arrhythmic medication. Manufactured by various pharmaceutical companies with various brand names, phenytoin (PHT) is also known as Dilantain, Hydantoin or Phenytek in the United States; Dilantain or Remytoine in Canada; Epamin, Hidantoina in Mexico; and Fenidatoin or Fenitron or other names elsewhere in the world. Phenytoin (PHT) is especially useful for patients suffering from intractable oral and facial pain especially those who exhibit anger, stress, depression and irrational emotions commonly seen in the patients with oral and facial pain. When used properly, Phenytoin is also an effective anxiolysis drug in addition to its theraputic effects on pain and can be used alone or, even better, if combined with other compatible sedatives. Phenytoin is particularly valuable when combined with acupuncture for patients with trigeminal neuralgia, glossopharyneal neuralgia, Bell's palsy, and some other facial paralysis and pain. It also has an advantage of keeping the patient relatively lucid after treatment. Either PHT or acupuncture alone can benefit patients but the success of treatment outcome may be limited. We found by combining both acupuncture and PHT with Selective Drug Uptake Enhancement by stimulating middle finger at the first segment of ventral (palmar) and lateral surfaces, as well as prescribing PHT with the dosage predetermined for each patient by Bi-Digital O-Ring Test (BDORT), the treatment outcome was much better resulted with less recurrence and intensity of pain during episodes of attack. Patients with Bell's palsy were most benefited by acupuncture therapy that could completely get rid of the illness.

    We present the first patient in New Zealand to undergo Spinal Cord Stimulation (SCS) for intractable upper abdominal pain. The patient was a 53-year-old man with a 20-year history of debilitating upper abdominal pain associated with chronic pancreatitis secondary to pancreatic divisum. Prior to the SCS, he was prescribed 680 mg of morphine sulphate equi-analgesia a day. Despite the intense analgesia, he still suffered monthly attacks of upper abdominal pain requiring hospitalisation. Nine months after implanting a Spinal Cord Stimulator, the monthly attacks ceased, his background pain was effectively controlled and the need for opioids decreased to 510 mg of morphine sulphate equi-analgesia a day.

    Full Text Available A multimodal stepped care approach has been successfully applied to a patient with complex regional pain syndrome type 1 and severe intractable pain, not responding to regular neuropathic pain medication. The choice to administer drugs in creams was made because of the intolerable adverse effects to oral medication. With this method, peak-dose adverse effects did not occur. The multimodal stepped care approach resulted in considerable and clinically relevant decrease in pain after every step, using topical amitriptyline, ketamine, and dimethylsulphoxide.

    Objective: To evaluate the therapeutic effect of neurolytic celiac plexus block (NCPB) and to analyze the factors related to the degree of pain relief. Methods: Forty-two patients who had intractable upper abdominal pain or accompanying referred back pain from cancer of pancreas, liver, stomach, colon and bile duct received bilateral alcohol neurolytic celiac plexus blocks under CT guidance. The results of pain relief were classified into 0-III grade. The spread of neurolytic solution (with contrast material) was observed through 3D reconstruction. Results: During the 3 months follow-up, the total effective rates of pain relief in 2 weeks, 1 month, 2 months and 3 months were 92.86%, 88.10%, 85.00% and 80.56% respectively. Satisfactory pain relief results were obtained when the neurolytic solution encircled the aorta adequately from two sides. There were no severe complications in any case. Conclusion: NCPB guided by CT proves to be an effective and safe means of controlling intractable upper abdominal cancer pain and should be popularized

    Authors report the effectiveness of MCS in extraordinarily extended pain due to intractable CRPS type II and rCBF study result for mechanism of pain control by MCS. A 43-year-old male presented severe spontaneous burning pain in his left hand and forearm and allodynia over the left arm and left hemibody. Authors planned MCS as a neuromodulation therapy for this intractable peripheral neuropathic pain patient because further neurodestructive procedure did not work anymore and have a potential risk of further aggrevation of neuopathic pain. We performed baseline and stimulation brain perfusion SPECT using 20 mCi of Tc-99m ECD. The baseline CBD studies were done with stimulator 'off' state and stimulation studies were done after stimulator 'on' with satisfactory pain relief. For the stimulation study, the radioisotope was injected immediately after pain-relief and the images were taken about 50 minutes after injection of radioisotope. In resting rCBF in the patient was compared with normal control datas, we found significant increase in rCBF in the bilateral prefrontal cortex, right dorsolateral prefrontal cortex, right superior temporal gyrus, left temporooccipital area. When rCBF datas obtained after alleviation of pain with stimulator 'on' . there were significant increase in rCBF in bilateral prefrontal cortex and left temporoocipital area. After subtraction of ECD SPECT, we found significant increase in rCBF in the right premotor and supplementary motor cortex left sensorimotor cortex, right cingulated cortex, right posterior insular cortex, right anterior limb of internal capsule. left orbitofrontal cortex and right pyramidal tract in cerebral peduncle.

    Objective: To evaluate the therapeutic effect of neurolytic cliac plexus block (NCPB), and to analyze the factors related to the degree of pain relief. Methods: Eight cases of the abdominal cancer with intractable pain from 7 days to 20 days, were treated by NCPB. During NCPB,10 ml or 15 ml, dehydrated alcohol was injected bilaterally for the former and unilateral for the latter. The results of pain relief were classified into four score-grade. The spread of alcohol was observed through CT scanning. Results: During the follow-up of 1W, 1M, 2M, 3M, 4M, 5M, 6M, the cases of pain relief ( ≥2 cases) were 7,7, 6, 5, 4, 3 and 3 cases respectively. With CT scanning, 7 cases showed the satisfactory spread of alcohol except 1 case which was not properly distributed. No severe complication occurred. Conclusions: NCPB guided by CT is an effective and safe method for treating intractable abdominal cancer pain

    ligation. These long-standing rheumatoid patients (suffering for five to 15 years), presented with at least four of the seven 1987 revised criteria of the American College of Rheumatology for diagnosis of rheumatoid arthritis. A 2.5 cm long and 2 cm deep tissue space was dissected and prepared in each transplant recipient at the axilla using diathermy and knife after infiltrating the site with one percent lignocaine solution. The tissue collected from the consenting mother undergoing hysterotomy and ligation was inserted into this site, and the site was closed with 00 atraumatic vicryl. All necessary pre- and postoperative surgical precautions were taken to prevent infections. Sequential total count and differential count of leucocytes were undertaken to analyze the impact of the transplant on the host. After one month, a part of the transplanted fetal tissue was recovered for histological staining to examine whether there was any graft versus host reaction. All ten patients tolerated the transplant procedure well. There was no fever, intractable pain or any other specific serious side-effect which could justify the removal of the transplant before one month. There was no discharge from the incision site and the healing of the scar was by and large normal. There was no unusual leucocytosis, lymphocytosis and the retrieved graft tissue did not suggest transplant rejection. However, there was definite pain relief, reduction in swelling and improvement of mobility of varying degree in a majority of the patients which was perceivable from the 15th day onwards. There was also a sense of well being (in 80%) and a gain in weight of three pounds or more (in 70%) among the fetal transplant recipients. To understand the underlying mechanism, in case of pregnancy immunotolerance, we are of the opinion that emphasis should be placed on the role of non-specific and non-cytopathic blocking antibodies produced during pregnancy.

Occasionally, it also causes neuropathic pain with spasticity. Traditional therapies for neuropathic pain are multiple, including multimodal analgesic regimens, antiepileptic or antidepressant medications, opioids, sympathetic blocks, and spinal cord stimulation. Persistent neuropathic pain can cause emotional distress by affecting sleep, work, recreation, and emotional well-being. Here we report the case of a patient suffering from intractable neuropathic pain following acute transverse myelitis that was not relieved by combinations of nonsteroidal anti-inflammatory, antiepileptic, antidepressant, and opioid medications, or by acupuncture. Implantation of an intrathecal morphine pump controlled the pain successfully without side effects, and enabled the patient to embark on intensive rehabilitation. The patient's muscle strength has improved significantly and the patient may soon be able to use a walker with minimal assistance.Keywords: intrathecal morphine pump, neuropathic pain, rehabilitation, transverse myelitis

    To examine the use of a new silver needle therapy for treating tender points involved in intractable low-back pain after removal of nucleus pulposus. The study involved 24 patients (17 men and 7 women) aged 26 to 67 years with a mean age of 54.5 +/- 5 years. The Department of Orthopedics at the First Military Medical University, the Department of Rehabilitation Medicine at the General Hospital of PLA in Beijing, and the Department of Acupuncture, the First People's Hospital in Kunming City, People's Republic of China, were the settings for this study. The patients were treated with traditional silver needle therapy at tender points in the low back and buttocks. Pain at each of the tender points was measured before and after treatment; the scores were compared with a Student t test. The therapeutic results suggest that the total scores for each tender point after treatment were significantly lower than those taken before treatment (P pain after surgery for disc herniation. Further clinical trials are needed to confirm the effectiveness of this treatment.

    To evaluate the effectiveness of dronabinol for the treatment of neuropathic pain refractory to previous treatment. We studied the response (reduction of pain intensity and functional improvement) to dronabinol (5 mg/day to 25 mg/day) in two adolescents with neuropathic pain and depression refractory to previous treatments over two and five years, respectively. Reduction in pain intensity (45%) was achieved in patient 2 and was unchanged in patient 1. Functional improvement was markedly increased in terms of academic performance, mood and sleep in both patients over four to five months, without major adverse effects. While these improvements dissipated over time, the patients were more reconnected with rehabilitation and focused less on the intrusiveness of their pain problem in their every day lives. Dronabinol appeared to be effective in improving pain affect and psychosocial functioning in the treatment of refractory neuropathic pain and may be considered as an adjuvant medication in the rehabilitation process. Well-controlled placebo studies are required for further evaluation.

    Neuropathic pain is one of the common complications after spinal cord injury (SCI), affecting patients' life quality. The molecular mechanism for neuropathic pain after SCI is still unclear. We aimed to discover potential genes and MicroRNAs(miRNAs) related to neuropathic pain by bioinformatics method. Microarray data of GSE69901 were obtained from Gene Expression Omnibus (GEO) database. Peripheral blood samples from patients with or without neuropathic pain after spinal cord injury (SCI) were collected. 12 samples with neuropathic pain and 13 samples without pain as control were included in the downloaded microarray. Differentially expressed genes (DEGs) between neuropathic pain group and control group were detected using GEO2R online tool. Functional enrichment analysis of DEGs was performed using DAVID database. Protein-protein interaction (PPI) network was constructed from STRING database. MiRNAs targeting these DEGs were obtained from miRNet database. A merged miRNA-DEG network was constructed and analyzed with Cytoscape software. Total 1134 DEGs were identified between patients with or without neuropathic pain(case and control) and 454 biological processes were enriched. We identified 4 targeted miRNAs, including mir-204-5p, mir-519d-3p, mir-20b-5p, mir-6838-5p, which may be the potential biomarker for SCI patients. Protein modification and regulation biological process of central nervous system may be a risk factor of in SCI patients. Certain genes and miRNAs may be potential biomarkers for the prediction of and potential targets for prevention and treatment of neuropathic pain after SCI.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

    1983-01-01

    Studied the relationships between depth of depression, anaclitic and introjective depressive experiences, and dimensions of illness behavior in 37 chronic pain patients. Depth of depression and degree of introjective depressive experiences showed similar positive covariation with a broad range of illness behavior: Namely, hypochondriasis, disease conviction, affective inhibition, affective disturbance, and irritability. The findings suggest that depression characterized by feelings of guilt, worthlessness, and self-doubt, rather than themes of abandonment, is associated differentially with disturbances in the illness behavior of chronic pain patients.

    Fournier gangrene (FG) is a necrotizing soft tissue infection involving the superficial and fascial planes of the perineum. In many cases of FG, debridement of the scrotum is necessary, leaving definitive management of the exposed testicles a significant surgical challenge. Frequent incidental trauma to the testicles can cause severe pain, especially in laborers. Practical surgical solutions are few and not well detailed. Various options exist, including creating a neoscrotum with adjacent thigh tissue, split-thickness skin grafts (STSGs), or even creating a subcutaneous thigh pocket. We describe a case of abdominal implantation of bilateral testicles for persistent testicular pain in a case where STSGs did not provide adequate protection, adjacent thigh skin was not available for creation of a neoscrotum, and significant cord contracture occurred. We detail the advantages and disadvantages of the commonly described techniques, including this approach, and how in select individuals this may be a suitable alternative.

    The incidence of glucocorticoid-induced osteoporosis is approximately 50% in patients treated for >6 months, and in the long-term usage fracture risk is approximately 34%. The awareness of pediatric vertebral fractures due to glucocorticoid-induced osteoporosis is increasing. Although most of these fractures are asymptomatic, a small number of children may have severe pain. In this case report we are presenting long-term result of a 9-year-old patient with intractable pain due to glucocorticoid-induced osteoporotic vertebral fracture managed by kyphoplasty. Case report. Case report of a 9-year-old girl who had L3 vertebral fracture due to glucocorticoid-induced osteoporosis treated by kyphoplasty. The patient was a 9-year-old girl with severe back pain, and lupus nephritis. Glucocorticoid-induced L3 vertebral fracture was detected and the case was resistant to conservative treatment. Seeing this, we have performed balloon kyphoplasty procedure to L3 vertebrae. No complication and pain was observed after the operation although L3 vertebral height could not restored. On the 8-year control, L3 vertebral height was almost totally restored with a compression index of 10% without any clinical problem. To the best of the authors' knowledge, the patient sample of this case report is the first and the youngest patient who was treated with kyphoplasty for vertebral compression fracture intractable pain due to glucocorticoid-induced osteoporosis, mentioned in literature. During the 8-year follow-up, no adverse effect was reported that was related to kyphoplasty procedure. This case report indicates that kyphoplasty can be an alternative method for selective pediatric intractable painful vertebral glucocorticoid-induced osteoporotic fractures, but it should be performed after careful consideration in pediatric group. We do not advise routine usage of kyphoplasty for pediatric vertebral fractures.

    Cancer and its treatment are stressful and reduce the quality of life in children. The aim of this study was to investigate the effect of massage therapy on pain and anxiety arising from intrathecal therapy or bone marrow aspiration in children with cancer. We conducted a controlled pretest/posttest quasi-experimental study at a paediatric oncology unit in Turkey. Twenty-five children were enrolled in this study. Their pain and anxiety were determined using a visual analogue scale. When the pretest and posttest pain and anxiety levels of the groups were compared, no statistically significant difference was found (P > 0.05). It was determined that pain and anxiety levels in the experimental group decreased significantly. This study provides preliminary evidence for the effectiveness in children of massage in reducing pain and anxiety arising from intrathecal therapy or bone marrow aspiration. © 2014 Wiley Publishing Asia Pty Ltd.

    Percutaneous vertebroplasty (PVP) is a minimally invasive outpatient procedure whereby vertebral compression fractures are stabilized by the injection of bone cement, or polymethyl methacrylate (PMMA). Rapid partial or complete pain relief can usually be achieved through this procedure. We prospectively evaluate the efficacy of PVP in the relief of pain and improvement in quality of life of patients with intractable pain from osteoporotic and metastatic fractures. Patients with intractable pain from vertebral metastases (many resistant to palliative radiation therapy) and patients with intractable painful osteoporotic fractures were treated with parapedicular or transpedicular injection of PMMA. Plane X-rays, computed tomography (CT) scan, and magnetic resonance imaging (MRI) scan were performed on all patients. With a reflex hammer, percussion pain was correlated to the imaging abnormalities. The preplanning CT scan was used to calculate the exact entry point and angle of the bone-biopsy needle. All patients were assessed before and after the procedure for quality of life and amount of pain. The following measures were used: 1) the Edmonton Symptom Assessment System (ESAS), for global pain, nausea, tiredness, depression, anxiety, drowsiness, appetite, sense of well-being, and shortness of breath; 2) a site-specific pain score (SSPS); 3) the amount of analgesic intake in morphine equivalents in the last 24 hours; and 4) the Townsend Functional Assessment Scale (TFAS), ascertaining mobility. A postprocedural CT scan was performed the same day on all patients. Follow-up assessment consisted of a phone call at Days 1, 2, and 4 and Weeks 1, 2, 4, 8, and 12. Patients with recurrent back pain or complications were followed in the bone metastases clinic. Thirty patients (19 women, 11 men) were evaluated. Their median age was 68 years (range 31 to 87 years). Thirty procedures (n=30) at 45 vertebral levels were performed; 13 were for pathologic fractures, and 17 were for

    Full Text Available We present a new perspective of neuromyopathy in pancreatic cancer pain (PCP referral to bodywall; proposal of new rationale to include ultrasound guided dry needling (USGDN of body wall muscles as an effective adjunct to neurolytic coeliac plexus block (NCPB or splanchnic nerve radiofrequency ablation (SRF for comprehensive interventional management. Methods: PCP response to SRF in 2 patients and NCPB in 3 patients was documented on numerical rating scale (NRS on post procedure days 3 and 15. If the residual pain was >5 NRS on day 15, USGDN of abdominal and back muscles was started on a thrice weekly basis. The response to USGDN documented on day 30 after approximately 6 sessions of DN, showed a significant pain reduction (0-2 NRS with 50% reduction of pre-treatment opioid consumption. This was sustained at 6 months or till their demise. Convergence of visceral and somatic nerves at the dorsal horn (viscerosomatic neurons causes referral of visceral pain to the back and abdominal muscles. This leads to formation of myofascial trigger points (MTrPs in the muscles which sets up a parallel network of sensitized peripheral and central motor nociceptive processing (neuromyopathy. USGDN specifically addressed the MTrPs that develop as an epiphenomenon of self-perpetuating neuromyopathy while SRF/NCPB, analgesics and neuromodulators could address only visceral nociceptive afferents (pain mediated through celiac plexus which forms a meagre 10% of the total spinal cord afferent input. Thus, we conclude that combination of neuromyopathy and viscerosomatic convergence in PCP indicate a specific role for DN as an adjunct to SRF/NCPB in our patients

    Full Text Available David Ip, Nga-Yue Fu Asia Medical Pain Centre, Mong Kok, Hong Kong, People's Republic of China Objective: The aim of the study reported here was to investigate the possible clinical role of low-level laser therapy (LLLT in discogenic back pain patients who failed to respond to a conventional physical therapy program to avoid recourse to operative intervention.Methods: The paper reports on the long-term mean 5-year prospective follow-up of a patient cohort of 50 unselected patients visiting our tertiary referral pain center for discogenic back pain who had had a single-level lesion documented by magnetic resonance imaging followed by subsequent discography to confirm the affected disc being the pain generator. All of the patients who entered the study had failed response to a combination of nonsteroidal anti-inflammatory agents and had had not less than 3 months of conventional physical therapy. LLLT, at a wavelength of 810 nm wavelength emitted from a GaAIAs semiconductor laser device with 5.4 J per point and a power density of 20 mW/cm2, was employed. The treatment regimen consisted of three sessions of treatment per week for 12 consecutive weeks.Results: All but one patient had significant improvement in their Oswestry Disability Index score, from a mean of 50% score to a mean of 10% score, at the end of treatment at 12 weeks. In addition, surprisingly, the improvement was found maintained at follow-up assessments 1 year and 5 years later. The one patient among the 50 patients who failed to respond eventually required surgery, while the others did not require surgery.Conclusion: We conclude that LLLT is a viable option in the conservative treatment of discogenic back pain, with a positive clinical result of more than 90% efficacy, not only in the short-term but also in the long-term, with lasting benefits.

    2000-05-01

    The aim of the present study was to investigate the effects of intramuscular injection with hypertonic saline, a well-established experimental model for muscle pain, on central processing of proprioceptive input from jaw muscle spindle afferents. Fifty-seven cells were recorded from the medial edge of the subnucleus interpolaris (Vi) and the adjacent parvicellular reticular formation from 11 adult cats. These cells were characterized as central units receiving jaw muscle spindle input based on their responses to electrical stimulation of the masseter nerve, muscle palpation and jaw stretch. Forty-five cells, which were successfully tested with 5% hypertonic saline, were categorized as either dynamic-static (DS) (n=25) or static (S) (n=20) neurons based on their responses to different speeds and amplitudes of jaw movement. Seventy-six percent of the cells tested with an ipsilateral injection of hypertonic saline showed a significant modulation of mean firing rates (MFRs) during opening and/or holding phases. The most remarkable saline-induced change was a significant reduction of MFR during the hold phase in S units (100%, 18/18 modulated). Sixty-nine percent of the DS units (11/16 modulated) also showed significant changes in MFRs limited to the hold phase. However, in the DS neurons, the MFRs increased in seven units and decreased in four units. Finally, five DS neurons showed significant changes of MFRs during both opening and holding phases. Injections of isotonic saline into the ipsilateral masseter muscle had little effect, but hypertonic saline injections made into the contralateral masseter muscle produced similar results to ipsilateral injections with hypertonic saline. These results unequivocally demonstrate that intramuscular injection with an algesic substance, sufficient to produce muscle pain, produces significant changes in the proprioceptive properties of the jaw movement-related neurons. Potential mechanisms involved in saline-induced changes in the

    Full Text Available Purpose: We present our experience with retroperitoneoscopic lymphatic disconnection for the treatment of patients with intractable chyluria. Materials and Methods: From November 1996 to March 2003, 12 patients (three females and nine males, with intractable chyluria were treated at our department with the retroperitoneoscopic technique. Diagnosis was based on urine examination for the presence of chyle and fat globules, cystoscopy, excretory urogram and retrograde ureteropyelography. The technique of retroperitoneoscopic management of chyluria consisted of nephrolympholysis, ureterolympholysis, hilar vessel stripping, fasciectomy and nephropexy. The first three procedures were done in all cases, whereas fasciectomy was only done in four cases and nephropexy in three as required. Results: Chyluria disappeared in all ipsilateral renal units of the patients who underwent retroperitoneoscopic management but it recurred in two patients at 1 and 9 months of follow up from the contralateral side. Both the cases have since been successfully treated with contralateral retroperitoneoscopic management. Complications included lymphatic leak through the drain, which persisted for 5 days in one case and an inadvertent clipping of a branch of the posterior segmental artery of the kidney in one. The latter patient did not have pain or hypertension and the renal scan did not reveal any focal deficit at follow up. All patients were followed periodically from 6 to54 months (mean of 31 months. Conclusion: Retroperitoneoscopic chylolymphatic disconnection is a safe and effective management of intractable chyluria. The reroperitoneoscopic approach provides direct access to the kidney without transgressing the peritoneum.

    Chronic migraine is a disabling disorder associated with myofascial and trigger point disorders in the neck. Pharmacological management is the first line of treatment; however, rehabilitation procedures aimed at lessening symptoms of myofascial and trigger point disorders may add value in the management of headache symptoms. The aim of this study was to evaluate the feasibility of myofascial and trigger point treatment in chronic migraine patients receiving prophylactic treatment with onabotulinumtoxinA. To evaluate the treatment effects on headache frequency and intensity, analgesic consumption, cervical range of motion, trigger point pressure pain threshold, quality of life, and disability. Pilot, single-blind randomized controlled trial with two parallel groups. Neurorehabilitation Unit. Twenty-two outpatients with chronic migraine. Patients were randomly assigned to receive either cervicothoracic manipulative treatment (N.=12) or transcutaneous electrical nerve stimulation (TENS) in the upper trapezius (N.=10). Treatment consisted of 4 sessions (30 min/session, 1 session/week for 4 weeks). A rater blinded to treatment allocation evaluated outcomes before treatment, during treatment, and 1 month after the end of treatment. Consistent with the pilot nature of the study, feasibility was considered the primary outcome and efficacy the secondary outcome. All patients completed the study. No adverse events were reported. No significant between-group differences in pain intensity were observed during the study period. At post-treatment evaluation, the total consumption of analgesics (P=0.02) and non-steroidal anti-inflammatory (P=0.02) drugs was significantly lower in the manipulative treatment group than in the TENS group. These effects paralleled significant improvements in trigger point sensitivity and cervical active range of motion. Manipulative techniques aimed at reducing peripheral nociceptive triggers might add value in the management of chronic migraine

    Rudmik, Luke

    2012-01-01

    Background: Epistaxis is a common otolaryngology emergency and is often controlled with first-line interventions such as cautery, hemostatic agents, or anterior nasal packing. A subset of patients will continue to bleed and require more aggressive therapy. Methods: Intractable spontaneous epistaxis was traditionally managed with posterior nasal packing and prolonged hospital admission. In an effort to reduce patient morbidity and shorten hospital stay, surgical and endovascular techniques have gained popularity. A literature review was conducted. Results: Transnasal endoscopic sphenopalatine artery ligation and arterial embolization provide excellent control rates but the decision to choose one over the other can be challenging. The role of transnasal endoscopic anterior ethmoid artery ligation is unclear but may be considered in certain cases when bleeding localizes to the ethmoid region. Conclusion: This article will focus on the management of intractable spontaneous epistaxis and discuss the role of endoscopic arterial ligation and embolization as it pertains to this challenging clinical scenario.

This is a prospective, randomized, head-to-head long-term outcome study. Forty patients with comparable patient demographics were randomly assigned to two cohorts. Cohort A trialed with intermittent boluses; Cohort B trialed with continuous infusion. One patient failed trial in each group. Nineteen patients were implanted in each group. Follow-up was for 36 months with intervals at 6, 12, 18, 24, 36 months. The Brief Pain Inventory was used was used for assessment. We used the Brief Pain Inventory to measure pain (worst and average), physical function (walking, normal work, and general activity), behavioral function (mood, sleep, and relations with others), IT dose, and oral opioid use. We observed statistically significant reduction in pain and improvement of function in both cohorts following DDS implantation throughout the observation period. The IT dose remained virtually unchanged throughout as well, with overall limited dose escalation. Oral opioid use was significantly reduced. There was no statistically significant difference in prediction of trial success or long-term outcomes between the two cohorts. Low-dose IT opioids via DDS can provide significant and long-lasting reduction in pain, and improvement in function (physical and behavioral) for patients with chronic nonmalignant pain. The two trialing techniques tested, intermittent boluses, and continuous infusion delivered intrathecally showed no clinical significance difference in terms of predicting trial success or long-term outcomes. © 2015 International Neuromodulation Society.

    Some intractable chronic cough remains a common complaint for seeking medical care. Unexplained cough in lupus nephropathy patient is rare and therapeutic options are limited. A 57 year-old woman with a 7-year history of lupus nephropathy. She has suffered from chronic cough for 3 years accompanied with chronic low back pain and fatigue, as the conventional therapy cannot relieve the symptoms. The woman is diagnosed as intractable cough after lupus nephropathy. 9 times space-time acupuncture (STA) treatment was performed. The cough, as well as other uncomfortable symptoms like chronic low-back pain and fatigue have resolved, and no relapse for one year follow-up. STA may be an effective therapy to treat intractable chronic cough. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

    We retrospectively evaluated the safety and efficacy of computed tomography-guided placement of percutaneous catheters in close proximity to the thoracic sympathetic chain by rating pain intensity and systematically reviewing charts and computed tomography scans. Interventions were performed 322 times in 293 patients of mean (SD) age 59.4 (17.0) years, and male to female ratio 105:188, with postherpetic neuralgia (n = 103, 35.1%), various neuralgias (n = 88, 30.0%), complex regional pain syndrome (n = 69, 23.6%), facial pain (n = 17, 5.8%), ischaemic limb pain (n = 7, 2.4%), phantom limb pain (n = 4, 1.4%), pain following cerebrovascular accident (n = 2, 0.7%), syringomyelia (n = 2, 0.7%) and palmar hyperhidrosis (n = 1, 0.3%). The interventions were associated with a total of 23 adverse events (7.1% of all procedures): catheter dislocation (n = 9, 2.8%); increase in pain intensity (n = 8, 2.5%); pneumothorax (n = 3, 0.9%); local infection (n = 2, 0.6%); and puncture of the spinal cord (n = 1, 0.3%). Continuous infusion of 10 ml.h(-1) ropivacaine 0.2% through the catheters decreased median (IQR [range]) pain scores from 8 (6-9 [2-10]) to 2 (1-3 [0-10]) (p < 0.0001). Chemical neuroablation was necessary in 137 patients (46.8%). We conclude that this procedure leads to a significant reduction of pain intensity in otherwise obstinate burning or stabbing pain and is associated with few hazards. © 2011 The Authors.

    This study compared the efficacy of a tetrahydrocannabinol:cannabidiol (THC:CBD) extract, a nonopioid analgesic endocannabinoid system modulator, and a THC extract, with placebo, in relieving pain in patients with advanced cancer. In total, 177 patients with cancer pain, who experienced inadequate analgesia despite chronic opioid dosing, entered a two-week, multicenter, double-blind, randomized, placebo-controlled, parallel-group trial. Patients were randomized to THC:CBD extract (n = 60), THC extract (n = 58), or placebo (n = 59). The primary analysis of change from baseline in mean pain Numerical Rating Scale (NRS) score was statistically significantly in favor of THC:CBD compared with placebo (improvement of -1.37 vs. -0.69), whereas the THC group showed a nonsignificant change (-1.01 vs. -0.69). Twice as many patients taking THC:CBD showed a reduction of more than 30% from baseline pain NRS score when compared with placebo (23 [43%] vs. 12 [21%]). The associated odds ratio was statistically significant, whereas the number of THC group responders was similar to placebo (12 [23%] vs. 12 [21%]) and did not reach statistical significance. There was no change from baseline in median dose of opioid background medication or mean number of doses of breakthrough medication across treatment groups. No significant group differences were found in the NRS sleep quality or nausea scores or the pain control assessment. However, the results from the European Organisation for Research and Treatment of Cancer Quality of Life Cancer Questionnaire showed a worsening in nausea and vomiting with THC:CBD compared with placebo (P = 0.02), whereas THC had no difference (P = 1.0). Most drug-related adverse events were mild/moderate in severity. This study shows that THC:CBD extract is efficacious for relief of pain in patients with advanced cancer pain not fully relieved by strong opioids. Copyright 2010 U.S. Cancer Pain Relief Committee.

    Use of bone-seeking radiopharmaceuticals is an established modality in the palliative care of pain due to skeletal metastases. 177 Lu-DOTMP is a promising radiopharmaceutical for this application owing to the ideally suited decay properties of 177 Lu and excellent thermodynamic stability and kinetic rigidity of the macrocyclic complex. The aim of the present study is to develop a robust and easily adaptable protocol for formulation of clinical doses of 177 Lu-DOTMP at hospital radiopharmacy. After extensive radiochemical studies, an optimized strategy for formulation of clinical doses of 177 Lu-DOTMP was developed, which involves simple mixing of approximately 3.7 GBq of 177 Lu activity as 177 LuCl 3 solution to an aqueous solution containing 5 mg of DOTMP and 8 mg of NaHCO 3 . The proposed protocol yielded 177 Lu-DOTMP with >98% radiochemical purity, and the resultant formulation showed excellent in vitro stability and desired pharmacokinetic properties in animal model. Preliminary clinical investigations in 5 patients showed specific skeletal accumulation with preferential localization in the osteoblastic lesion sites and almost no uptake in soft tissue or any other major nontarget organ. The developed "mix-and-use" strategy would be useful for large number of nuclear medicine centers having access to 177 Lu activity and would thereby accelerate the clinical translation of 177 Lu-DOTMP.

  14. Sequencing intractable DNA to close microbial genomes.

    Directory of Open Access Journals (Sweden)

    Richard A Hurt

    Full Text Available Advancement in high throughput DNA sequencing technologies has supported a rapid proliferation of microbial genome sequencing projects, providing the genetic blueprint for in-depth studies. Oftentimes, difficult to sequence regions in microbial genomes are ruled "intractable" resulting in a growing number of genomes with sequence gaps deposited in databases. A procedure was developed to sequence such problematic regions in the "non-contiguous finished" Desulfovibrio desulfuricans ND132 genome (6 intractable gaps and the Desulfovibrio africanus genome (1 intractable gap. The polynucleotides surrounding each gap formed GC rich secondary structures making the regions refractory to amplification and sequencing. Strand-displacing DNA polymerases used in concert with a novel ramped PCR extension cycle supported amplification and closure of all gap regions in both genomes. The developed procedures support accurate gene annotation, and provide a step-wise method that reduces the effort required for genome finishing.

  15. The intractable cigarette 'filter problem'.

    2011-05-01

    became the fundamental cigarette filter material. By the mid-1960s, the meaning of the phrase 'filter problem' changed, such that the effort to develop effective filters became a campaign to market cigarette designs that would sustain the myth of cigarette filter efficacy. This study indicates that cigarette designers at Philip Morris, British-American Tobacco, Lorillard and other companies believed for a time that they might be able to reduce some of the most dangerous substances in mainstream smoke through advanced engineering of filter tips. In their attempts to accomplish this, they developed the now ubiquitous cellulose acetate cigarette filter. By the mid-1960s cigarette designers realised that the intractability of the 'filter problem' derived from a simple fact: that which is harmful in mainstream smoke and that which provides the smoker with 'satisfaction' are essentially one and the same. Only in the wake of this realisation did the agenda of cigarette designers appear to transition away from mitigating the health hazards of smoking and towards the perpetuation of the notion that cigarette filters are effective in reducing these hazards. Filters became a marketing tool, designed to keep and recruit smokers as consumers of these hazardous products.

    2014-01-01

    Full Text Available We describe a treatment alternative for intractable, startle-provoked, epileptic seizures in four children aged between 8 and 14. Three of the four children had symptomatic localization-related epilepsy. They all suffered from intractable epilepsy precipitated by sudden sounds. The fact that seizures tended to occur with high frequency – more than one seizure a day – had a clear impact on daily life. Clinical seizure pattern demonstrated asymmetric tonic posturing in all four children. Three children experienced several seizure types including focal seizure onset. All children had focal neurological signs or learning disabilities or a combination of both. Our noninvasive treatment method using psychoeducational counseling and sound generators was applied in four children, resulting in a seizure frequency reduction of ≥50% in two of them.

    Our aim was to assess the value of diffusion tensor imaging (DTI) in patients with partial intractable epilepsy. We used DTI (25 non-collinear directions) in 15 patients with a cortical lesion on conventional MRI. Fractional anisotropy (FA) was measured in the internal capsule, and in the normal-appearing white matter (WM), adjacent tothe lesion, and away from the lesion, at a set distance of 2-3 cm. In each patient, increased or decreased FA measurements were those that varied from mirror values using an arbitrary 10% threshold. Over the whole population, ipsi- and contralateral FA measurements were also compared using a Wilcoxon test (p<0.05). Over the whole population, FA was significantly reduced in the WM adjacent to and away from the lesion, whilst being normal in the internal capsule. FA was reduced by more than 10% in the WM adjacent to and distant from the lesion in 13 and 12 patients respectively. For nine of the ten patients for whom the surgical resection encompassed the limits of the lesion on conventional MRI, histological data showed WM alterations (gliosis, axonal loss, abnormal cells). DTI often reveals WM abnormalities that are undetected on conventional MRI in patients with partial intractable epilepsy. (orig.)

    Purpose: In patients with trigeminal neuralgia, severe pain can persist, or recur despite aggressive medical management and open surgery. Recently, Gamma Knife radiosurgery has been used with promising results. We report on our series of 26 patients with intractable trigeminal neuralgia treated with stereotactic Gamma Knife radiosurgery. Materials and Methods: Between 1991 and 1995, 26 patients with intractable trigeminal neuralgia were treated at our institution using stereotactic Gamma Knife radiosurgery. Medical management had failed in all cases. In addition, 13 patients underwent a total of 20 open surgeries, with transient, or no pain relief. There were 19 females, and 7 males. Patient ages ranged from 37 to 87 years, with a median of 74 years. All patients were treated with a 201 source Cobalt-60 Gamma Knife unit. All patients underwent placement of the Leksell frame, followed by MRI scanning and computer treatment planning. The target in all patients was the fifth cranial nerve root entry zone into the brainstem. Twenty-five patients received between 64.3 to 70 Gy prescribed to Dmax in one shot. One patient received 120 Gy to Dmax in one shot. The 4 mm collimator was used in 22 cases, and the 8 mm in 4 cases. Follow-up ranged from 5 to 55 months, with a median of 19 months. Complete resolution (CR) of pain was scored when the patient reported being pain free off all medication. Partial resolution (PR) was scored when the patient reported > 50% pain reduction after Gamma Knife treatment. Results: At last follow-up, 84.6% ((22(26))) reported CR or PR of pain after Gamma Knife treatment. Forty-two percent ((11(26))) of patients reported CR, and 42%((11(26))) reported PR of pain. There was a dose response. In patients receiving < 70 Gy, 25% ((3(12))) reported CR, while 57% ((8(14))) of those receiving ≥ 70 Gy reported CR. Complications occurred in two (8%) patients. One patient developed transient numbness of the face after 70 Gy, and a second patient

    Purpose: To assess the efficacy and safety of microcatheter embolization in the treatment of intractable idiopathic epistaxis. Methods: Thirty-seven patients underwent microcatheter embolization in 1991-1998. We evaluated retrospectively the technical and clinical outcome, the number of complications, the duration of embolization in each case, and the number of blood transfusions needed. All embolizations were done with biplane digital subtraction angiography (DSA) equipment. The procedure was carried out under local anesthesia using transfemoral catheterization, except in one case where the translumbar route was used. Tracker 18 or 10 microcatheters were advanced as far as possible to the distal branches of the sphenopalatine artery. Polyvinyl alcohol (PVA) particles were used for embolization in most cases, while platinum coils or a combination of these two materials were occasionally used. The primary outcome was always assessed immediately by angiography. Follow-up data were obtained from patient records, by interviewing patients on the telephone or by postal questionnaires when necessary. The mean follow-up time was 21 months. Results: The embolization was technically successful in all 37 cases. A curative outcome was achieved in 33 cases (89%). The mean duration of the procedure was 110 min. Four patients (8%) had mild transient complications, but no severe or persistent complications were encountered. Twenty-three patients needed a blood transfusion. Slight rebleeding occurred in three patients during the follow-up; all responded to conservative treatment. One patient suffered two episodes of rebleeding within 2 months after primary embolization. Re-embolizations successfully stopped the bleeding. Conclusion: Embolization is the primary invasive modality for treating intractable idiopathic epistaxis. It proved both safe and effective over a relatively long follow-up

Methods: TAE using gel form or polyvinyl alcohol (PVA) particles of forty-one patients with intractable epistaxis were undertaken by the femoral artery approach, through selective catheterization of involved maxillary artery or the bleeding arteries for the stoppage of bleeding. Results: Of the forty-one patient, 39 cases were cured by once TAE and the other 2 with recurrent bleeding on the next day after the TAE, to whom a second interventional treatment full filled the requirement. Conclusions: Transcatheter arterial embolization is a simple, safe and effective treatment for the intractable epistaxis. (authors)

  11. Omega-Conotoxins as Experimental Tools and Therapeutics in Pain Management

    Directory of Open Access Journals (Sweden)

    Heidi E. Hannon

    2013-03-01

    Full Text Available Neuropathic pain afflicts a large percentage of the global population. This form of chronic, intractable pain arises when the peripheral or central nervous systems are damaged, either directly by lesion or indirectly through disease. The comorbidity of neuropathic pain with other diseases, including diabetes, cancer, and AIDS, contributes to a complex pathogenesis and symptom profile. Because most patients present with neuropathic pain refractory to current first-line therapeutics, pharmaceuticals with greater efficacy in pain management are highly desired. In this review we discuss the growing application of ω-conotoxins, small peptides isolated from Conus species, in the management of neuropathic pain. These toxins are synthesized by predatory cone snails as a component of paralytic venoms. The potency and selectivity with which ω-conotoxins inhibit their molecular targets, voltage-gated Ca2+ channels, is advantageous in the treatment of neuropathic pain states, in which Ca2+ channel activity is characteristically aberrant. Although ω-conotoxins demonstrate analgesic efficacy in animal models of neuropathic pain and in human clinical trials, there remains a critical need to improve the convenience of peptide drug delivery methods, and reduce the number and severity of adverse effects associated with ω-conotoxin-based therapies.

    PurposeWe evaluated the management of transcatheter arterial embolization for postpartum hemorrhage caused by vaginal laceration.Materials and MethodsWe reviewed seven cases of patients (mean age 30.9 years; range 27–35) with intractable hemorrhages and pelvic hematomas caused by vaginal lacerations, who underwent superselective transcatheter arterial embolization from January 2008 to July 2014. Postpartum hemorrhage was evaluated by angiographic vascular mapping to determine the vaginal artery’s architecture, technical and clinical success rates, and complications.ResultsThe vaginal artery was confirmed as the source of bleeding in all cases. The artery was found to originate from the uterine artery in three cases, the uterine and obturator arteries in two, or the internal pudendal artery in two. After vaginal artery embolization, persistent contrast extravasation from the inferior mesenteric artery as an anastomotic branch was noted in one patient. Nontarget vessels (the inferior vesical artery and nonbleeding vaginal arterial branches) were embolized in one patient. Effective control of hemostasis and no post-procedural complications were confirmed for all cases.ConclusionPostpartum hemorrhages caused by vaginal lacerations involve the vaginal artery arising from the anterior trunk of the internal iliac artery with various branching patterns. Superselective vaginal artery embolization is clinically acceptable for the successful treatment of vaginal laceration hemorrhages, with no complications. After vaginal artery embolization, it is suggested to check for the presence of other possible bleeding vessels by pelvic aortography with a catheter tip at the L3 vertebral level, and to perform a follow-up assessment.

  13. Caring for Patients With Intractable Neurological Diseases

    Directory of Open Access Journals (Sweden)

    Masako Nagase

    2014-08-01

    Full Text Available This is a qualitative descriptive study examining nurses’ attitudes about caring for patients with intractable neurological diseases, with a focus on dedication and conflicts. Semistructured interviews were conducted on 11 nurses with more than 5 years of clinical experience in addition to more than 3 years of experience in neurology wards. Senior nursing officers from each hospital selected the participants. In general, these nurses expressed distress over the inevitable progression of disease. Nurses talked about the “basis of dedication,” “conflicts with dedication,” “reorganization for maintaining dedication,” and “the reason for the change from conflict to commitment.” “Reorganization for maintaining dedication” meant that nurses were able to handle the prospect of rededicating themselves to their patients. Furthermore, “the reason for the change from conflict to commitment” referred to events that changed nurses’ outlooks on nursing care, their pride as nurses, or their learning experiences. They felt dedicated and conflicted both simultaneously and separately. While committing to their patients’ physical care, nurses were empowered to think positively and treat patients with dignity in spite of the care taking much time and effort, as well as entailing considerable risk.

    1986-01-01

    Eleven patients with intractable rheumatoid arthritis were treated with fractionated total lymphoid irradiation, (total dose 20 Gy). Lasting improvement in clinical symptoms was found in four patients during treatment and the remaining patients experienced similar benefit within 2 months of irradiation. There was marked reduction in exacerbations and number of joints involved. Morning stiffness, joint swelling and tenderness decreased. Complications included severe fatigue during treatment and acute bacterial arthritis in multiple joints in one patient. Four patients have since died, one of renal failure, another of cardiogenic shock following surgery 3 and 24 months after total lymphoid irradiation. Both had generalised amyloidosis. The third patient developed joint empyema and died of toxic cardiac failure. The fourth died 3 months after resection of a Kaposi's sarcoma complicated by wound infection which responded to treatment. Immunologically, total lymphoid irradiation resulted in suppression of the absolute lymphocyte count and reduction in T-helper cells, the number of T-suppressor cells remaining unchanged. These data provide evidence of T-cell involvement in the pathogenesis of rheumatoid arthritis. Total lymphoid irradiation can induce sustained improvement in clinical disease activity, but severe, possibly fatal, side-effects cannot be ignored. (author)

    Psychogenic seizures can mimic convulsive epilepsy and with repetitive attacks, iatrogenic complications from aggressive treatment of status epilepticus can occur. We studied neuropsychiatric features of 20 patients in whom psychogenic seizures were intractable and at times continuous. Nineteen of 20 patients seen were female, and all but one were under 40 years of age. All had convulsive attacks resistant to various medications, normal neurological examinations, and negative imaging studies and electroencephalograms (EEGs). Sixteen had previous evidence of epilepsy and the other four had epileptic relatives. Seizures were atypically prolonged, included back arching and pelvic thrusting, and persisted despite intravenous diazepam and therapeutic phenytoin and phenobarbital levels. Seizures terminated spontaneously in five, were stopped by suggestion in four, and persisted until respiratory arrest or elective intubation in 11. Ten patients had conversion disorder, six borderline or mixed personality disorder and four mental retardation. Fifteen had had some precipitating stressor and the remainder had histories of exhibiting attention-seeking behaviour. Nine of 10 patients with conversion disorder had 'conversion V' Minnesota Multiphasic Personality Inventory (MMPI) profiles, while personality disorder patients had elevation of several psychopathological scales. Patients with conversion disorder gradually improved with anticonvulsant discontinuation, while retarded individuals were helped by behaviour modification, situational change or neuroleptics. Personality disorder patients continued to have attacks and eventually discontinued follow-up. Clinical evidence of non-epileptic seizures includes clinical atypicality and long duration, exacerbation by medications and frequent attacks despite normal examination and studies.(ABSTRACT TRUNCATED AT 250 WORDS)

    production. The synthetic plastic cellulose acetate became the fundamental cigarette filter material. By the mid-1960s, the meaning of the phrase ‘filter problem’ changed, such that the effort to develop effective filters became a campaign to market cigarette designs that would sustain the myth of cigarette filter efficacy. Conclusions This study indicates that cigarette designers at Philip Morris, British-American Tobacco, Lorillard and other companies believed for a time that they might be able to reduce some of the most dangerous substances in mainstream smoke through advanced engineering of filter tips. In their attempts to accomplish this, they developed the now ubiquitous cellulose acetate cigarette filter. By the mid-1960s cigarette designers realised that the intractability of the ‘filter problem’ derived from a simple fact: that which is harmful in mainstream smoke and that which provides the smoker with ‘satisfaction’ are essentially one and the same. Only in the wake of this realisation did the agenda of cigarette designers appear to transition away from mitigating the health hazards of smoking and towards the perpetuation of the notion that cigarette filters are effective in reducing these hazards. Filters became a marketing tool, designed to keep and recruit smokers as consumers of these hazardous products. PMID:21504917

    Solitary osteochondromas are common benign long bone tumors originating from cartilage. They may produce a wide variety of symptoms and complications depending on their spinal location. These may include compressive myelopathy, nerve root compression, pathologic fracture and malignant degeneration, or in some cases only pain. Solitary cervical spine osteochondromas have been reported mostly in the neural arch or vertebral body. This report describes a patient presenting with neck pain, with a benign osteochondroma arising in the right bifid C5 lamina.

    Full Text Available Surgery of temporal lobe epilepsy is the best opportunity for seizure freedom in medically intractable patients. The surgical approach has evolved to recognize the paramount importance of the mesial temporal structures in the majority of patients with temporal lobe epilepsy who have a seizure origin in the mesial temporal structures. For those individuals with medically intractable mesial temporal lobe epilepsy, a selective amygdalohippocampectomy surgery can be done that provides an excellent opportunity for seizure freedom and limits the resection to temporal lobe structures primarily involved in seizure genesis.

    Full Text Available Background: Regarding the complications of chronic intractable epilepsy, the presence of respectable lesions in many these patients that can be diagnosed with noninvasive sensitive techniques such as MRI and SPECT and the unrecognized significance of epilepsy surgery in our country, we have decided to review the management of medically intractable epilepsy in patients, who underwent epilepsy surgery in neurosurgery department of Loghman Hakim hospital between 1997-2003. Materials and Methods: In this study we retrospectively review 30 cases of medically intractable epilepsy that had underwent epilepsy surgery. All patients before surgery were investigated with brain MRI, brain SPECT, EEG and IQ test. Type of surgery was determined by MRI, SPECT and EEG findings. Pre - and postoperative seizure frequency and surgery complications studied. Seizure control was measured with Engel criteria. Results: Patients mean age was 22.4 years. Three cases (10% were females that all underwent temporal mesial lobectomy. In 18 cases (60% there were concordant brain lesion with seizure origin that 9 cases (30% underwent mesial temporal lobectomy and remainder 9 cases (30% underwent lesionectomy.other12 cases (40% that have uncertain brain lesion but suffer from drop attack due to one or combination of atonic, tonic, tonic clonic, clonic, myoclonic, absence or clonic underwent anterior callosotomy. patients that underwent mesial temporal lobectomy, anterior callosotomy and lesionectomy were seizure-free in 77.7%, 58.3% and 55.5% of cases respectively. Conclusions: Provided to correct patient selection for epilepsy surgery we can manage intractable epilepsy properly. Regarding to the complication of intractable epilepsy, acceptable epilepsy surgery results and available sensitive noninvasive diagnostic techniques such as MRI in our country, epilepsy surgery should be considered seriously in our country and promoted.

    We examined the effect of acupuncture on epileptic seizures in humans in a controlled clinical setting. Treatment was administered by two Chinese professors of acupuncture. Effect was measured by change in seizure frequency. Twenty-nine patients with chronic intractable epilepsy completed the study. They were randomized in two groups; 15 were given classical acupuncture and 14 were given sham acupuncture. There was a reduction in seizure frequency in both groups, which did not reach a level of statistical significance. There was also an increase in the number of seizure-free weeks in both groups, which reached a level of significance in the sham group. Thus, we have not been able to prove a beneficial effect of acupuncture in chronic intractable epilepsy. Copyright 1999 BEA Trading Ltd.

    The study was designed to evaluate the efficacy, safety, and tolerability of the ketogenic diet (KD) whether classic 4:1 formula or the modified Atkins diet (MAD) in intractable childhood epilepsy. Anthropometric measurements and serum lipid profile were measured upon enrollment and after 3 and 6 months in 40 patients with symptomatic intractable epilepsy. Fifteen were given MAD diet, ten were kept on classic 4:1 ketogenic liquid formula, and the rest were allowed to eat as desired. The liquid ketogenic formula group showed significantly higher body mass index compared with those who did not receive KD after 6 months. The lipid profile of KD patients was within normal limits for age and sex during the study period. The rate of change of frequency and severity of seizures showed best improvement in ketogenic liquid formula patients followed by the MAD group than the patients on anti-epileptic medications alone. The KD whether classic 4:1 or MAD is a tolerable, safe, and effective adjuvant therapy for intractable symptomatic childhood epilepsy with limited adverse effects on the growth parameters and accepted changes in the lipid profile. The liquid ketogenic formula patients showed better growth pattern and significantly more seizure control. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2006-04-01

    Hemispherectomy is the most successful operation for the control of seizures in a very select group of patients with infantile hemiplegia and intractable epilepsy. The efficacy of anatomical hemispherectomy has been offset to some degree by the fact that up to one third of those operated upon will subsequently develop obstructive hydrocephalus, and the so-called superficial subpial cerebral hemosiderosis, with potentially fatal complications. This review article details the operative technique of a modified `functional` hemispherectomy. In essence, the technique consists of removing the central (Rolandic) cortex and the temporal lobe of the affected hemisphere and leaving the remainder of the hemisphere intact, but neurogenically disconnected from the remaining brain.

    Central neuropathic itch can be a lifelong debilitating condition and treatment challenge. We report a patient with a traumatic brain injury with severe intractable pruritus who failed extensive pharmacologic and nonpharmacologic treatment but responded to a holistic approach using healing touch. We discuss the complexity of this type of neuropathic itch and present a holistic approach as an adjunct to therapy in reducing itch intensity. This case presentation along with the literature discussed suggests a therapeutic strategy for the management of complicated central neuropathic itch.

    Obsessive-compulsive disorder (OCD) is a chronic, disabling disorder. Psychosurgery may be indicated for a subset of patients for whom no conventional treatment is satisfactory. This paper focuses on the stereotactic subcaudate tractotomy (SST). Thus far, these procedures have been carried out using frame-based stereotactic techniques. However, modern - highly accurate - frameless stereotactic procedures have successfully been introduced in neurosurgical practice. We developed a novel frameless stereotactic subcaudate tractotomy procedure with promising initial results in a patient suffering from intractable OCD. This is the first report on frameless SST. Future studies should examine whether other ablative stereotactic psychosurgery procedures can be done using frameless stereotactic methods.

  18. Luisa's Ghosts: Haunted Legality and Collective Expressions of Pain.

    Science.gov (United States)

    Krauss, Amy

    2018-04-25

    Feminist health care providers have debated the efficacy of the decriminalization of abortion in Mexico City. Luisa, a counselor in a private clinic, suggested that while the law has expanded the visibility of, and access to safe abortion, it has also called forth "other ghosts." In this article, I take Luisa's critical perspective as a starting point for examining ongoing criminalization and moral stigma as forms of haunting that arise in the wake of the Mexico City abortion policy. Drawing on ethnographic research, I explore how Luisa's ghosts materialize in the embodied- affective relations between patients in new legal clinics. Women who attend public clinics negotiate moral stigma along with religious and familial pressures in the ways they suffer, as well as normalize abortion as a painful experience. Rather than approach pain as purely a sign of victimization, I suggest that its expression constitutes an effervescent collectivity between women in the clinic, making explicit, while at the same time dissipating, an intractable moral-affective knot that might otherwise be ignored.

    2014-01-01

    Five studies across cultures involving 661 American Democrats and Republicans, 995 Israelis, and 1,266 Palestinians provide previously unidentified evidence of a fundamental bias, what we term the “motive attribution asymmetry,” driving seemingly intractable human conflict. These studies show that in political and ethnoreligious intergroup conflict, adversaries tend to attribute their own group’s aggression to ingroup love more than outgroup hate and to attribute their outgroup’s aggression to outgroup hate more than ingroup love. Study 1 demonstrates that American Democrats and Republicans attribute their own party’s involvement in conflict to ingroup love more than outgroup hate but attribute the opposing party’s involvement to outgroup hate more than ingroup love. Studies 2 and 3 demonstrate this biased attributional pattern for Israelis and Palestinians evaluating their own group and the opposing group’s involvement in the current regional conflict. Study 4 demonstrates in an Israeli population that this bias increases beliefs and intentions associated with conflict intractability toward Palestinians. Finally, study 5 demonstrates, in the context of American political conflict, that offering Democrats and Republicans financial incentives for accuracy in evaluating the opposing party can mitigate this bias and its consequences. Although people find it difficult to explain their adversaries’ actions in terms of love and affiliation, we suggest that recognizing this attributional bias and how to reduce it can contribute to reducing human conflict on a global scale.

    Full Text Available Aims. To acquire normative data of hippocampal volumes and T2 relaxation times, to evaluate and compare qualitative and quantitative assessments in evaluating hippocampi in patients with different durations of intractable epilepsy, and to propose an imaging protocol based on performance of these techniques. Methods. MRI analysis was done in 50 nonepileptic controls and 30 patients with intractable epilepsy on 1.5T scanner. Visual assessment and hippocampal volumetry were done on oblique coronal IR/T2W and T1W MP-RAGE images, respectively. T2 relaxation times were measured using 16-echo Carr-Purcell-Meiboom-Gill sequence. Volumetric data was normalized for variation in head size between individuals. Patients were divided into temporal ( and extratemporal ( groups based on clinical and EEG localization. Results. In controls, right hippocampal volume was slightly more than the left with no effect of age or gender. In TLE patients, hippocampal volumetry provided maximum concordance with EEG. Visual assessment of unilateral pathology concurred well with measured quantitative values but poorly in cases with bilateral pathologies. There were no significant differences of mean values between extratemporal group and controls group. Quantitative techniques detected mild abnormalities, undetected on visual assessment. Conclusions. Quantitative techniques are more sensitive to diagnose bilateral and mild unilateral hippocampal abnormalities.

    Full Text Available Background Epilepsy is a chronic disease that requires antiepileptic drugs (AEDs. Only 60-70% of new patients could be controlled effectively by standard AEDs and this stimulates the search for new, more effective and well-tolerated AEDs. Objective To asses the efficacy and safety of topiramate, as an adjunctive therapy to standard AEDs for children with intractable epilepsy. Methods This was an open label, parallel group study. Forty children with at least 4 seizures during a 4-week baseline period were randomly assigned to topiramate (n=20 or control group (n=20. In the topiramate group, the drug was given in adjunct to AEDs for  2-week titration dosage continued with a 12-week stabilization period, while the control group received only AEDs adjusted to their clinical responses. Results Mean reduction from baseline in monthly seizures frequency was significantly greater in the topiramate group (88.6% vs. 25%; P=0.030. Other variable of efficacy was significantly different (e"50% reduction in seizures: 14/20 vs. 6 /20; P=0.049. Adverse effects of topiramate, such as decreased weight, paresthesia, somnolence, diarrhea, fever, aggressive reaction and flushing, were temporary and mild. Conclusion Results of this trial strongly suggested that topiramate is effective and well tolerated in reducing seizures of intractable epilepsy.

    2015-10-08

    The article examines the political socialization of young Jewish-Israeli children who live under the Israeli-Palestinian intractable conflict. It proposes arguments and presents empirical evidence to suggest that the way in which political socialization of young children happens in this context contributes to the development of conflict-supporting narratives of ethos of conflict and collective memory by the youngest generation. As a result, the conflict solidifies adherence to these narratives in adulthood, thereby serving as a major obstacle to the processes of peace-making and peace-building. Specifically, as evidence for showing how the political socialization works in Israel, a series of studies conducted in Israeli kindergartens and elementary schools are presented. These studies recount the contents acquired by young children, as well as contents delivered by teachers, related to the Israeli-Palestinian conflict. This indicates the serious consequences of acquiring conflict-supporting narratives at an early age in societies involved in intractable conflict. © 2015 by the Society for Personality and Social Psychology, Inc.

    2005-05-01

    To investigate the common nasal bleeding points and the management of intractable epistaxis. The bleeding points and its correlation with age distribution, surgical techniques as well as its effects were studied retrospectively in 92 patients, in whom the bleeding points were not found by routine nasal endoscopy and the hemorrhage was not controlled with standard nasal packing. The bleeding points were found in the following different sites: superior wall of inferior nasal meatus (56.5%, 52/92), olfactory cleft of nasal septum (27.2%, 25/92), posterosuperior wall of middle nasal meatus (8.7%, 8/92) and uncertain (7.6%, 7/92). The results showed that the bleeding points had correlation with age. Epistaxis was well controlled by electrocoagulation in 83 cases, gelfoam packing in 8 cases, and transcatheter maxillary artery embolization in 1 case. There were no complications during a followed-up for 1 - 3 months after management. Among the 92 cases, the numbers of treatment needed to stop bleeding were 82 cases (89.1%) after 1 time of treatment, 9 cases (9.8%) after 2 times and in one case (1.1%) after 4 times. Endoscopy combined with displacement of the middle and inferior turbinate gives good visualization and direct management of the deeply-sited bleeding points, which were difficult in localization. The combined method provides an effective and safe way to control intractable epistaxis.

    Many children with constipation fail to respond with conventional medical therapy. Surgery can produce a good result in dysfunction of the colon secondary to aganglionosis. However, its role in treating idiopathic constipation is more controversial. A consecutive series of 44 patients with chronic idiopathic intractable constipation were included in this study. All children were investigated by barium enema and anorectal manometry. Due to inadequate response to medical therapy, all of these patients were selected for internal sphincter myomectomy. Patients were followed-up from 3 to 12 months. Short-term (3 months) and long-term (6 months) follow-up was available for all patients. The histology examinations showed normal ganglion cells in 32, hypoganglionosis in eight and aganglionosis in four patients. In short-term, regular bowel habits, without the need for laxatives or low dose drugs were recorded in 35 patients (79.5%). Overall there was an improvement in 68.2% of the children after 6 months follow-up. There was not any correlation between histopathological findings, duration of symptoms, age and sex of operation and response to myectomy. anorectal myectomy is an effective procedure in patients with intractable idiopathic constipation. It relieves symptoms in 68.2% of patients with chronic refractory constipation.

Embolization was performed in 58 patients (39 males aged 24-48 and 19 females aged 26-44) admitted to the ENT Department, Medical University of Bialystok in years 2000 -2005. 65 embolization procedures, including reembolizations, were performed. In 41 procedures (63%) a sponge was used, in 14 (21.6%) PVA, in 10 (15.4%) PVA and coils. In 9 patients, bleeding of a lesser intensity recurred within early hours following the procedure - 84.5% embolization success. On longer follow-up, embolization success was assessed to be 100%. Embolization with the use of proper embolisation materials is an efficient method of arresting spontaneous and posttraumatic epistaxis and may be a safe treatment procedure when performed by experienced medical personnel.

    Lateral ankle pain is a common clinical presentation having several important causes, including lateral ligament injury, peroneal tendon injury, sinus tarsi syndrome, and nerve entrapments. However, other causes should be kept in mind in patients with unusual patterns of pain or intractable symptoms. We present a review of common and some unusual causes of lateral ankle pain including a review of post-operative imaging findings following surgery for lateral ankle ligament and peroneal tendon injuries.

    The aim of the study was to assess the treatment efficacy of transanal irrigation and parental satisfaction in children with intractable functional constipation (FC) treated with Peristeen. Cross-sectional survey study among parents of children (age 0-18 years) treated with Peristeen for FC (based on the Rome III criteria). Anonymous questionnaires were sent out to parents via mail, these consisted of 25 self-developed, multiple-choice questions regarding the use of Peristeen, current gastrointestinal symptoms, adverse effects of Peristeen, concomitant medication use, and parental satisfaction. Out of 91 invited families, 67 (74%) returned the questionnaire. In total, 84% of patients experienced fecal incontinence prior to treatment. Out of all children who still used Peristeen at the time of survey (n = 49), fecal incontinence had resolved completely in 41%, 12% experienced occasional episodes of fecal incontinence (children (42%) experienced pain during rectal irrigation, especially during insertion of the catheter, inflating the balloon, or during irrigation. Overall, 86% of the parents were satisfied with the result of transanal irrigation and 67% reported that they would continue using transanal irrigation for the treatment of their child's symptoms. Transanal irrigation may be effective in the treatment of children with FC and renders a high parental satisfaction. Future prospective studies, preferably RCTs, are necessary to further evaluate this treatment option.

    Cancer-related facial pain refractory to pharmacologic management or nondestructive means is a major indication for destructive pain surgery. Stereotactic mesencephalotomy can be a valuable procedure in the management of cancer pain involving the upper extremities or the face, with the assistance of magnetic resonance imaging (MRI) and electrophysiologic mapping. A 72-year-old man presented with a 3-year history of intractable left-sided facial pain. When pharmacologic and nondestructive measures failed to provide pain alleviation, he was reexamined and diagnosed with inoperable hard palate cancer with intracranial extension. During the concurrent chemoradiation treatment, his cancer-related facial pain was aggravated and became medically intractable. After careful consideration, MRI-based stereotactic mesencephalotomy was performed at a point 5 mm behind the posterior commissure, 6 mm lateral to and 5 mm below the intercommissural plane using a 2-mm electrode, with the temperature of the electrode raised to 80℃ for 60 seconds. Up until now, the pain has been relatively well-controlled by intermittent intraventricular morphine injection and oral opioids, with the pain level remaining at visual analogue scale 4 or 5. Stereotactic mesencephalotomy with the use of high-resolution MRI and electrophysiologic localization is a valuable procedure in patients with cancer-related facial pain.

    Full Text Available Achievement of seizure free is the ultimate goal of patients with epilepsy. Lifelong treatment may be needed in some epileptic children, especially in those with intractable epilepsy. To be more realistic, this goal may be modified to reduce the frequency of more disabling types of seizures. Chronic seizures influence children in social activities, psychology,cognition as well as many other aspects. Therefore, their long-term management requires concerted lifelong care of pediatricians, neurologists and social workers. During the course of treatment, doctors should evaluate the patients regularly, prevent and control the side effects of antiepileptic drugs (AEDs and monitor patients for AEDs-associated adverse events. In addition, doctors should choose the optimal therapeutic regimen for patients with refractory epilepsy, and achieve a balance between benefit and risk in order to improve the quality of life of patients.

    To evaluate the efficacy, safety and tolerability of a modified Atkins diet in intractable childhood epilepsy. Fourteen children with epilepsy were treated prospectively with a modified Atkins diet. Outcome measures included seizure frequency, adverse reactions and tolerability to the diet; blood beta-hydroxybutyrate and urine ketones were also measured. Six months after diet initiation, seven (50%) remained on the diet, five (36%) had >50% seizure reduction, and three (21%) were seizure free. The diet was well tolerated by 12 (86%) patients. Most complications were transient and were successfully managed by careful follow-up and conservative strategies. A consistently strong ketosis (beta-hydroxybutyrate of >3 mmol/L) seemed to be important for maintaining the efficacy of the diet therapy. The modified Atkins diet was well tolerated and sometimes a modified Atkins diet can be substituted for the conventional ketogenic diet. Serious complications were rare, but long-term complications remain to be determined.

    Pain may be the initial symptom in oral cancer, and is a common complaint both in patients awaiting treatment and in those already in treatment. However, little has been published in the literature on the management of oral cancer pain. Effective pain control requires a multimodal approach in which pharmacological management based on the World Health Organization (WHO) analgesic ladder continues to play an essential role. Although different routes are available for the administration of analgesics, oral delivery continues to be the principal route for pain control in the first instance. Interventional approaches include blockade of a peripheral nerve or of the relevant ganglion, and the use of central neuraxial blockade. The intraventricular or intrathecal administration of opioids, with or without local anaesthetics, has been indicated for severe intractable pain. The development of new treatment modalities provides additional options, though further clinical research is required. There is no evidence of the efficacy of non-pharmacological methods such as acupuncture or transcutaneous nerve stimulation in the management of oral cancer pain. Surgery, radiation therapy, and chemotherapy have also been suggested, but their results have not been quantified. Copyright 2010 Elsevier Ltd. All rights reserved.

    Palat Gayatri

    2005-01-01

    Full Text Available Cancer of the cervix uteri is a common cause of pain among women. On the physical realm, the cancer may cause somatic [soft tissue and bone], visceral and neuropathic pain [lumbosacral plexopathy]. Radiotherapy and chemotherapy may cause neuropathy too. Psychological, social and cultural factors modify the pain. Evaluation of the individual type of pain and a patient-centred approach are fundamental requirements for rational management. Disease modifying treatment like radiotherapy and chemotherapy must be considered when applicable. Pain control is usually achieved by the use of WHO three-step ladder, remembering that possible association of renal dysfunction would necessitate caution in the use of NSAIDs and opioids. Side effects must be anticipated, prevented when possible, and aggressively treated; nausea and vomiting may already be present, and constipation can worsen pain when there is a pelvic mass. Pain emergencies can be treated by quick titration with intravenous morphine bolus doses. Neuropathic pain may warrant the use of usual adjuvants, with particular reference to cortico-steroids and the NMDA antagonist, ketamine. In intractable pain, many neurolytic procedures are tried, but a solid evidence base to justify their use is lacking. Continuous epidural analgesia with local anaesthetic and opioid may be needed when drug therapy fails, and desperate situations may warrant interventions such as neurolysis. Such physical measures for pain relief must be combined with psychosocial support and adequate explanations to the patient and the family.

    A 32-year old woman was found at surgery to have an esophageal leiomyoma arising within an epiphrenic diverticulum. These uncommon conditions may rarely occur together, causing difficulty in diagnosis of the leiomyoma. Other neoplasms may also arise in an epiphrenic diverticulum and should be borne in mind in this situation. (orig.)

    Intractable bleeding caused by radiation-induced gastritis is rare. We describe a 69-year-old man with intractable hemorrhagic gastritis induced by postoperative radiotherapy for the treatment of esophageal carcinoma. Although anti-secretory therapy with or without octreotide was initiated for hemostasis over three months, melena still occurred off and on, and the patient required blood transfusions to maintain stable hemoglobin. Finally growth hormone was used in the treatment of hemorrhage for two weeks, and hemostasis was successfully achieved. This is the first report that growth hormone has been used to control intractable bleeding caused by radiation-induced gastritis.

    In glaucoma filtration surgery, the problem of subconjunctival scarring has still not been satisfactorily solved. Suprachoroidal drainage of aqueous humour offers a promising, alternative option for intractable glaucoma. We here present a clinical study on the surgical approach of gonioscopic cyclodialysis ab interno. Twenty-eight eyes of 20 patients with intractable glaucoma were included in this prospective, consecutive, case-control study. The eyes had had a mean of 4.4 +/- 2.4 previous antiglaucomatous interventions. Baseline intraocular pressure (IOP) was 34.3 +/- 10.5 mmHg despite maximum therapy. Under gonioscopic control, cyclodialysis ab interno was performed over two clock times to gain access to the suprachoroidal space. No additional trabecular meshwork surgery was performed. Success was defined as a lowering of IOP to below 21 mmHg without the need for further medication or intervention. Mean postoperative IOP was 14.6 +/- 12.4 mmHg. Mean follow-up (FU) for all eyes was 121.8 days. After a mean of 60 days, 21 eyes (75%) needed further surgical intervention. Qualified success was seen in four eyes (14.3%), with a mean FU of 383.6 days. Three eyes (10.7%) showed absolute success after a mean FU period of 202.7 days. In our series, we obtained the best results for phakic eyes, followed by pseudophakic and aphakic eyes. The results of this study do not provide convincing evidence of the functional efficacy of cyclodialysis ab interno. Nevertheless, the technique is easy to perform and offers safe and atraumatic access to the resorptive capability of the choroid. Conjunctival manipulation is avoided. Contrary to reports in the current literature, in our series, the best results were obtained for phakic eyes, though the small number of eyes included does not allow reliable statistics. Further studies will need to focus on the use of different space-retaining substances or a widening of the cyclodialysis cleft to improve surgical outcome.

    1983-01-01

    Total lymphoid irradiation (TLI) was administered to 11 patients who had intractable rheumatoid arthritis that was unresponsive to conventional medical therapy, including aspirin, multiple nonsteroidal antiinflammatory drugs, gold salts, and D-penicillamine. Total lymphoid irradiation was given as an alternative to cytotoxic drugs such as azathioprine and cyclophosphamide. After radiotherapy, 9 of the 11 patients showed a marked improvement in clinical disease activity as measured by morning stiffness, joint tenderness, joint swelling, and overall functional abilities. The mean improvement of disease activity in all patients ranged from 40-70 percent and has persisted throughout a 13-28 month followup period. This improvement permitted the mean daily steroid dose to be reduced by 54%. Complications included severe fatigue and other constitutional symptoms during radiotherapy, development of Felty's syndrome in 1 patient, and an exacerbation of rheumatoid lung disease in another. After therapy, all patients exhibited a profound T lymphocytopenia, and a reversal in their T suppressor/cytotoxic cell to helper cell ratio. The proliferative responses of peripheral blood mononuclear cells to phytohemagglutinin, concanavalin A, and allogeneic leukocytes (mixed leukocyte reaction) were markedly reduced, as was in vitro immunoglobulin synthesis after stimulation with pokeweed mitogen. Alterations in T cell numbers and function persisted during the entire followup period, except that the mixed leukocyte reaction showed a tendency to return to normal values

    Eleven patients with intractable rheumatoid arthritis were treated with total lymphoid irradiation (total dose, 2000 rad) in an uncontrolled feasibility study, as an alternative to long-term therapy with cytotoxic drugs such as cyclophosphamide and azathioprine. During a follow-up period of five to 18 months after total lymphoid irradiation, there was a profound and sustained suppression of the absolute lymphocyte count and in vitro lymphocyte function, as well as an increase in the ratio of Leu-2 (suppressor/cytotoxic) to Leu-3 (helper) T cells in the blood. Persistent circulating suppressor cells of the mixed leukocyte response and of pokeweed mitogen-induced immunoglobulin secretion developed in most patients. In nine of the 11 patients, these changes in immune status were associated with relief of joint tenderness and swelling and with improvement in function scores. Maximum improvement occurred approximately six months after irradiation and continued for the remainder of the observation period. Few severe or chronic side effects were associated with the radiotherapy

    Tardive dystonia (TD) represents a side effect of prolonged intake of dopamine receptor blocking compounds. TD can be a disabling movement disorder persisting despite available medical treatment. Deep brain stimulation (DBS) has been reported successful in this condition although the number of treated patients with TD is still limited to small clinical studies or case reports. The aim of this study was to present the systematical overview of the existing literature regarding DBS for intractable TD. A literature search was carried out in PudMed. Clinical case series or case reports describing the patients with TD after DBS treatment were included in the present overview. Literature search revealed 19 articles reporting 59 individuals operated for TD. GPi was the target in 55 patients, while subthalamic nucleus (STN) was the target in the remaining 4. In most studies the motor part of Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) was improved by more than 80% when compared to preoperative BFMDRS scores. The performed literature analysis indicates that bilateral GPi DBS is an effective treatment for disabling TD. The response of TD to bilateral GPi DBS may be very rapid and occurs within days/weeks after the procedure. The efficacy of bilateral GPi DBS in TD patients is comparable to results achieved in patients with primary generalized dystonia. Copyright © 2016 Polish Neurological Society.

  8. Recurrent failings of medical humanitarianism: intractable, ignored, or just exaggerated?

    2017-11-18

    Humanitarian health workers operate in dangerous and uncertain contexts, in which mistakes and failures are common, often have severe consequences, and are regularly repeated, despite being documented by many reviews. This Series paper aims to discuss the failures of medical humanitarianism. We describe why some of these recurrent failings, which are often not identified until much later, seem intractable: they are so entrenched in humanitarian action that they cannot be addressed by simple technical fixes. We argue that relief health-care interventions should be contextualised. Perhaps medical humanitarianism deserves a better reputation than the one at times tarnished by unfair criticism, resulting from inapplicable guiding principles and unrealistic expectations. The present situation is not conducive to radical reforms of humanitarian medicine; complex crises multiply and no political, diplomatic, or military solutions are in sight. Relief agencies have to compete for financial resources that do not increase at the same pace as health needs. Avoiding the repetition of failures requires recognising previous mistakes and addressing them through different policies by donors, stronger documentation and analysis of humanitarian programmes and interventions, increased professionalisation, improved, opportunistic relationships with the media, and better ways of working together with local health stakeholders and through indigenous institutions.

    Intracranial bleeding following stereoelectroencephalography (sEEG) is rare and commonly occurs early after electrode implantation. The authors report the case of a delayed intracranial hematoma following sEEG. This 10-year-old boy was referred to the authors' department to undergo an sEEG study for intractable epilepsy, with the hypothesis of a single localized epileptic zone in the left precentral region. To perform the exploration, 14 depth electrodes were implanted under stereotactic conditions. The results of a postoperative CT scan performed routinely at the end of the surgical procedure were normal. Eight days later, following an epileptic seizure, the child's condition worsened. The neurological examination revealed a left hemiparesis, agitation, and coma due to a right subdural hematoma with intraparenchymal bleeding. Despite a surgical evacuation followed by a decompressive craniectomy, the curative treatments were stopped 1 week later due to severe diffuse ischemic lesions found on MRI studies. This is the first observation of a delayed hematoma following an sEEG procedure. The mechanism underlying this complication remains unclear, but the rupture of a growing pseudoaneurysm caused by the electrode's implantation or the tearing of a neighboring vessel by an electrode were suspected. In consequence, physicians must remain vigilant during the entire sEEG recording period and probably also several days after electrode removal.

    To investigate the clinical efficacy of individual endovascular management for the treatment of different traumatic pseudo aneurysms presenting as intractable epistaxis. For 14 consecutive patients with traumatic pseudo aneurysm presenting as refractory epistaxis, 15 endovascular procedures were performed. Digital subtraction angiography revealed that the pseudo aneurysms originated from the internal maxillary artery in eight patients; and all were treated with occlusion of the feeding artery. In six cases, they originated from the internal carotid artery (Inca); out of which, two were managed with detachable balloons, two with covered s tents, one by means of cavity embolization, and the remaining one with parent artery occlusion. All of these cases were followed up clinically from six to 18 months, with a mean follow up time of ten months; moreover, three cases were also followed with angiography. Complete cessation of bleeding was achieved in all the 15 instances (100%) immediately after the endovascular therapies. Of the six patients who suffered from Inca pseudo aneurysms, one presented with a permanent stroke and one had an episode of rebleeding requiring intervention. In patients presenting with a history of cranio cerebral trauma, traumatic pseudo aneurysm must be considered as a differential diagnosis. Individual endovascular treatment is a relatively safe, plausible, and reliable means of managing traumatic pseudo aneurysms

Materials and Methods For 14 consecutive patients with traumatic pseudoaneurysm presenting as refractory epistaxes, 15 endovascular procedures were performed. Digital subtraction angiography revealed that the pseudoaneurysms originated from the internal maxillary artery in eight patients; and all were treated with occlusion of the feeding artery. In six cases, they originated from the internal carotid artery (ICA); out of which, two were managed with detachable balloons, two with covered stents, one by means of cavity embolization, and the remaining one with parent artery occlusion. All of these cases were followed up clinically from six to 18 months, with a mean follow up time of ten months; moreover, three cases were also followed with angiography. Results Complete cessation of bleeding was achieved in all the 15 instances (100%) immediately after the endovascular therapies. Of the six patients who suffered from ICA pseudoaneurysms, one presented with a permanent stroke and one had an episode of rebleeding requiring intervention. Conclusion In patients presenting with a history of craniocerebral trauma, traumatic pseudoaneurysm must be considered as a differential diagnosis. Individual endovascular treatment is a relatively safe, plausible, and reliable means of managing traumatic pseudoaneurysms. PMID:21076585

    Full Text Available Osteomalacia is a form of metabolic bone disease that can present as chronic pain. A 36-year-old woman presented with a three-year history of bilateral leg and back pain, and proximal leg weakness. Repeated consultations and investigations failed to discover a cause for her pain, and a diagnosis of chronic benign pain was made. She was admitted to hospital where the bone scan, laboratory investigation and bone biopsy established a diagnosis of renal phosphate-wasting adult-onset rickets (osteomalacia. Radiographs of the hip and magnetic resonance imaging revealed bilateral femoral neck fractures and segmental, avascular necrosis of the femoral heads. The patient was treated with high dose phosphate and vitamin D with marked relief of pain. Osteomalacia should be considered in unusual cases of intractable chronic pain.

    Melatonin, which is used to treat sleep disorders, has anticonvulsant properties. The authors measured salivary melatonin and cortisol, at baseline and following seizures, in patients with intractable temporal lobe epilepsy and controls. Melatonin was reduced in patients with epilepsy at baseline compared with controls, and increased threefold following seizures. Cortisol also increased following seizures. Patients with intractable epilepsy have low baseline melatonin levels that increase dramatically following seizures. PMID:11113238

    Epilepsy is an important disease that affects brain function, particularly in those under 3 years old. Uncontrolled seizures can affect cognitive function and quality of life. For these reasons, many trials have been conducted to investigate treatments for pediatric epilepsy. Currently, many antiepileptic drugs are available for the treatment of epilepsy, but cases of intractable epilepsy continue to exist. In the past, cannabis has been tested as a potential treatment of intractable epilepsy...

    Genetically modified (GM) crops may contain newly expressed proteins that are described as "intractable". Safety assessment of these proteins may require some adaptations to the current assessment procedures. Intractable proteins are defined here as those proteins with properties that make it extremely difficult or impossible with current methods to express in heterologous systems; isolate, purify, or concentrate; quantify (due to low levels); demonstrate biological activity; or prove equivalency with plant proteins. Five classes of intractable proteins are discussed here: (1) membrane proteins, (2) signaling proteins, (3) transcription factors, (4) N-glycosylated proteins, and (5) resistance proteins (R-proteins, plant pathogen recognition proteins that activate innate immune responses). While the basic tiered weight-of-evidence approach for assessing the safety of GM crops proposed by the International Life Sciences Institute (ILSI) in 2008 is applicable to intractable proteins, new or modified methods may be required. For example, the first two steps in Tier I (hazard identification) analysis, gathering of applicable history of safe use (HOSU) information and bioinformatics analysis, do not require protein isolation. The extremely low level of expression of most intractable proteins should be taken into account while assessing safety of the intractable protein in GM crops. If Tier II (hazard characterization) analyses requiring animal feeding are judged to be necessary, alternatives to feeding high doses of pure protein may be needed. These alternatives are discussed here. Copyright © 2014 The Authors. Published by Elsevier Inc. All rights reserved.

  3. Indices of resective surgery effectiveness for intractable nonlesional focal epilepsy.

    Blume, Warren T; Ganapathy, Gobi R; Munoz, David; Lee, Donald H

    2004-01-01

    Among 70 patients with intractable focal epilepsy and no specific lesion, as determined by both MRI (magnetic resonance imaging) and histopathology, outcome after resective surgery was polarized: 26 (37%) became seizure free (SF), and 27 (39%) were not helped. Eighteen (42%) of 43 standard temporal resections rendered patients SF, somewhat more than eight (30%) of 27 other procedures. To seek reliable prognostic factors, the subsequent correlative data compared features of the 26 SF patients with those of the 27 not helped. Although ictal semiology guided the site of surgical resection, it and other aspects of seizure and neurologic history failed to predict surgical outcome. However, two aspects of preoperative scalp EEGs correlated with SF outcomes: (a) among 25 patients in whom >50% of clinical seizures arose from the later resected lobe and no other origins, 18 (72%) became SF compared with seven (28%) of 25 with other ictal profiles; (b) 13 (93%) of 14 temporal lobe patients whose interictal and ictal EEGs lacked features indicative of multifocal epileptogenesis became SF compared with five (33%) of 15 with such components. The considered need for subdural (SD) EEG reduced SF outcome from 18 (90%) of 20 patients without SD to eight (24%) of 33 with SD; this likely reflected an insufficient congruity of ictal semiology and interictal and ictal scalp EEG for localizing epileptogenesis. Within this SD group, >50% of clinical seizure origins from a later resected lobe increased SF outcome somewhat: from two (14%) of 14 without this attribute to six (40%) of 15 with it; 100% of such origins increased SF outcome from two (12%) of 16 to six (46%) of 13.

    Long-term ketogenic diet (KD) treatment has been shown to induce liver steatosis and gallstone formation in some in vivo and clinical studies. The aim of this retrospective study was to evaluate the hepatic side effects of KD in epileptic children. A total of 141 patients (mean age: 7.1±4.1years [2-18 years], 45.4% girls), receiving KD at least one year for intractable epilepsy due to different diagnoses (congenital brain defects, GLUT-1 deficiency, West syndrome, tuberous sclerosis, hypoxic brain injury, etc.) were included in the study. Serum triglyceride, cholesterol, aminotransferase, bilirubin, protein and albumin levels and abdominal ultrasonography were recorded before and at 1, 3, 6, and 12 months following after diet initiation. The mean duration of KD was 15.9±4.3months. At one month of therapy, three patients had elevated alanine and aspartate aminotransferase levels. These patients were receiving ketogenic diet for Doose syndrome, idiopathic epilepsy and GLUT-1 deficiency. Hepatosteatosis was detected in three patients at 6 months of treatment. Two of these patients were treated with KD for the primary diagnosis of tuberous sclerosis and one for Landau Kleffner syndrome. Cholelithiasis was detected in two patients at 12 months of treatment. They were receiving treatment for West syndrome and hypoxic brain injury sequelae. Long-term ketogenic diet treatment stimulates liver parenchymal injury, hepatic steatosis and gallstone formation. Patients should be monitored by screening liver enzymes and abdominal ultrasonography in order to detect these side effects. Copyright © 2016 British Epilepsy Association. Published by Elsevier Ltd.

    2016-08-01

    Pain in the orofacial region is a common presenting symptom. The majority of symptoms are related to dental disease and the cause can readily be established, the problem dealt with, and the pain eliminated. However, pain may persist and defy attempts at treatment. Intractable oral or facial pain can be diagnostically challenging. To make a definitive diagnosis and initiate proper treatment, a rigorous protocol for evaluation includes a thorough history and an appropriate comprehensive clinical examination and diagnostic testing, including chief complaint, history of present illness, medical history, physical examination, diagnostic studies, including imaging, and psychosocial evaluation.

    Full Text Available Background Phantom limb pain is a common problem after limb amputation (41-85%. It is described as an extremely painful sensation in the missing part of the body that can last for hours, days or even years. It is considered to arise from cortical reorganization, although many factors can increase the risk of phantom limb pain: pain before surgery, age and sex of the patients, the time elapsed since surgery, stump pain, inadequate prosthesis. Phantom limb pain therapy is very complicated. Case report We reported a case of 80-year-old patient suffering from phantom limb pain and phantom sensation 25 years after the amputation of his left leg due to the injury. The patient has pain at the site of amputation, sensation that he has the leg and that it occupies an unusual position and almost daily exhausting phantom limb pain (6-9 visual analogue scale - VAS with disturbed sleep and mood. We managed to reduce the pain under 4 VAS and decrease the patient suffering by combining drugs from the group of coanalgetics (antidepressants, antiepileptics, non-pharmacological methods (transcutaneous electroneurostimulation - TENS, mirror therapy and femoral nerve block in the place of disarticulation of the left thigh. Conclusion Phantom limb pain therapy is multimodal, exhausting for both the patient and the physician and it is often unsuccessful. The combination of different pharmacological and non-pharmacological modalities can give satisfactory therapeutic response.

    The objective was to document and describe the clinical features of a hemangioblastoma arising from a submandibular gland. A case report of a 63-year-old man with a right submandibular gland hemangioblastoma. Submandibular gland excision and histological examination revealed a hemangioblastoma. Subsequent evaluation with imaging studies found no association with von Hippel-Lindau disease. We report the first presentation of a hemangioblastoma arising in a salivary gland. Further evaluation of patients with a hemangioblastoma is recommended given the neoplasms' association with von Hippel-Lindau disease.

    Tumors that develop in old burn scars are usually squamous cell carcinomas. Sarcomas have also been reported, albeit rarely. To our knowledge, there has been only one case report of an extraskeletal osteosarcoma arising in a prior burn scar reported in the English-language literature, mainly discussing the clinicopathological features. Herein, we present a case of cutaneous osteosarcoma visualized as a mineralized soft-tissue mass arising from the scar associated with a previous skin burn over the back. This seems to be the first report describing the imaging features of a cutaneous osteosarcoma from an old burn scar. (orig.)

    To demonstrate the safety and effectiveness of responsive stimulation at the seizure focus as an adjunctive therapy to reduce the frequency of seizures in adults with medically intractable partial onset seizures arising from one or two seizure foci. Randomized multicenter double-blinded controlled trial of responsive focal cortical stimulation (RNS System). Subjects with medically intractable partial onset seizures from one or two foci were implanted, and 1 month postimplant were randomized 1:1 to active or sham stimulation. After the fifth postimplant month, all subjects received responsive stimulation in an open label period (OLP) to complete 2 years of postimplant follow-up. All 191 subjects were randomized. The percent change in seizures at the end of the blinded period was -37.9% in the active and -17.3% in the sham stimulation group (p = 0.012, Generalized Estimating Equations). The median percent reduction in seizures in the OLP was 44% at 1 year and 53% at 2 years, which represents a progressive and significant improvement with time (p < 0.0001). The serious adverse event rate was not different between subjects receiving active and sham stimulation. Adverse events were consistent with the known risks of an implanted medical device, seizures, and of other epilepsy treatments. There were no adverse effects on neuropsychological function or mood. Responsive stimulation to the seizure focus reduced the frequency of partial-onset seizures acutely, showed improving seizure reduction over time, was well tolerated, and was acceptably safe. The RNS System provides an additional treatment option for patients with medically intractable partial-onset seizures. © 2014 The Authors.

    This report presents a case history of intractable facial pain following the placement of a posterior mandibular implant. The pain was resistant to all medical management, but a cone beam computed tomography (CBCT) scan showed that the implant impinged on an unusual accessory inferior alveolar nerve. The decision to remove the implant led to significant pain reduction. This clinical example underscores the need for scrupulous imaging prior to implant placement.

    Full Text Available Marcela Romero-Reyes, James M Uyanik Orofacial and Head Pain Service, Department of Oral and Maxillofacial Pathology Radiology and Medicine, New York University College of Dentistry, New York, NY, USA Abstract: Some of the most prevalent and debilitating pain conditions arise from the structures innervated by the trigeminal system (head, face, masticatory musculature, temporomandibular joint and associated structures. Orofacial pain (OFP can arise from different regions and etiologies. Temporomandibular disorders (TMD are the most prevalent orofacial pain conditions for which patients seek treatment. Temporomandibular disorders include a number of clinical problems that involve the masticatory musculature, the temporomandibular joint (TMJ or both. Trigeminal neuropathic pain conditions can arise from injury secondary to dental procedures, infection, neoplasias, or disease or dysfunction of the peripheral and/or central nervous system. Neurovascular disorders, such as primary headaches, can present as chronic orofacial pain, such as in the case of facial migraine, where the pain is localized in the second and third division of the trigeminal nerve. Together, these disorders of the trigeminal system impact the quality of life of the sufferer dramatically. A multidisciplinary pain management approach should be considered for the optimal treatment of orofacial pain disorders including both non-pharmacological and pharmacological modalities.

    The ketogenic diet (KD) is an effective treatment for children with drug-resistant epilepsy and has been widely used in young children. Adult patients with intractable epilepsy would also benefit from this dietary treatment. However, only a few studies have been published, and the use of the KD in intractable epilepsy in adults has been limited. This meta-analysis summarized the findings of the relevant published studies to identify the efficacy of the KD for the treatment of intractable epilepsy in adults. In this meta-analysis, PubMed, Embase, and Cochrane Library were used for searching studies concerning the effects of the KD and its major subtypes with intractable epilepsy in adults published up to January 10, 2017. The primary outcomes were seizure freedom, seizure reduction by 50% or more, and seizure reduction by epilepsy were 13%, 53%, and 27%, respectively. The adverse reactions of the KD were mild, whereas low glycemic index diet (LGID) and low-dose fish oil diet (LFOD) may have fewer side effects. Weight loss, high level of low-density lipoprotein, and elevated total cholesterol were most frequent. The meta-analysis indicates that the KD for refractory epilepsy in adults is a well-tolerated treatment and that its side effects are acceptable, which show that the KD is a promising treatment in adult intractable epilepsy. Further research is needed to assess which type of diet or ratio is more effective in the KD treatment.

    Some studies have suggested that semicircular canal occlusion is effective and safe for treating intractable posterior semicircular benign paroxysmal positional vertigo (PSC-BPPV), and adverse effects of canal occlusions for intractable horizontal semicircular BPPV (HSC-BPPV) were rarely reported. The aim of this study was to retrospectively discuss the efficacy of semicircular canal occlusion for intractable HSC-BPPV with at least 2 years of follow-up. From 2000 to 2011, 3 female patients (average age=60±6.9 years), with a diagnosis of HSC-BPPV refractory to head-shake and barbecue roll maneuver, underwent semicircular canal occlusion treatment in our hospital. The supine roll test was performed to diagnose HSC-BPPV and evaluate the treatment efficacy. All patients with intractable HSC-BPPV had complete resolution of their positional vertigo after semicircular canal occlusion with a negative supine roll test. All patients reported transient postoperative disequilibrium, nausea, and vomiting, which resolved within 2 weeks. In addition, 1 patient (33.3%) had transient tinnitus, which resolved after 4 months. There were no other significant long-term complications. Semicircular canal occlusion appears to be a safe and well-tolerated treatment modality for intractable HSC-BPPV. However, further studies with large sample sizes are needed to confirm our conclusion. © The Author(s) 2014.

    Full Text Available Endometriosis is a frequent benign disorder. Malignancy arising in extraovarian endometriosis is a rare event. A 49-year-old woman is presented with a large painful abdominal wall mass. She underwent a myomectomy, 20 years before, for uterus leiomyoma. Computed tomography suggested that this was a desmoid tumor and she underwent surgery. Histological examination showed a clear cell adenocarcinoma associated with endometriosis foci. Pelvic ultrasound, computed tomography, and endometrial curettage did not show any malignancy or endometriosis in the uterus and ovaries. Adjuvant chemotherapy was recommended, but the patient was lost to follow up. Six months later, she returned with a recurrence of the abdominal wall mass. She was given chemotherapy and then she was reoperated.

    Full Text Available Pathological fractures in cancer patient cause severe pain that is difficult to control pharmacologically. Even with good pain relief at rest, breakthrough and incident pain can be unmanageable. Continuous regional nerve blocks have a definite role in controlling such intractable pain. We describe two such cases where severe pain was adequately relieved in the acute phase. Continuous femoral nerve block was used as an efficient, cheap and safe method of pain relief for two of our patients with pathological fracture femur. This method was proved to be quite efficient in decreasing the fracture-related pain and improving the level of well being.

    Full Text Available Chronic pelvic pain (CPP is defined as nonmalignant pain perceived in the structures related to the pelvis that has been present for more than 6 months or a non acute pain mechanism of shorter duration. Pain in the pelvic region can arise from musculoskeletal, gynaecological, urologic, gastrointestinal and or neurologic conditions. Key gynaecological conditions that contribute to CPP include pelvic inflammatory disease (PID, endometriosis, adnexa pathologies (ovarian cysts, ovarian remnant syndrome, uterine pathologies (leiomyoma, adenomyosis and pelvic girdle pain associated with pregnancy. Several major and minor sexually transmitted diseases (STD can cause pelvic and vulvar pain. A common painful condition of the urinary system is Interstitial cystitis(IC. A second urologic condition that can lead to development of CPP is urethral syndrome. Irritable bowel syndrome (IBS is associated with dysmenorrhoea in 60% of cases. Other bowel conditions contributing to pelvic pain include diverticular disease,Crohn′s disease ulcerative colitis and chronic appendicitis. Musculoskeletal pathologies that can cause pelvic pain include sacroiliac joint (SIJ dysfunction, symphysis pubis and sacro-coccygeal joint dysfunction, coccyx injury or malposition and neuropathic structures in the lower thoracic, lumbar and sacral plexus. Prolonged pelvic girdle pain, lasting more than 6 months postpartum is estimated in 3% to 30% of women. Nerve irritation or entrapment as a cause of pelvic pain can be related to injury of the upper lumbar segments giving rise to irritation of the sensory nerves to the ventral trunk or from direct trauma from abdominal incisions or retractors used during abdominal surgical procedures. Afflictions of the iliohypogastric, ilioinguinal, genitofemoral, pudendal and obturator nerves are of greatest concern in patients with pelvic pain. Patient education about the disease and treatment involved is paramount. A knowledge of the differential

    We describe a case of surgical treatment of intractable temporal epilepsy in a female patient with congenital middle cranial fossa encephalocele. We present clinical-anamnestic and neuroimaging data as well as the microscopic and macroscopic pictures of encephalocele. We analyze outcomes of surgery for this pathology, which have been reported in the literature. To date, there have been a few articles on this subject in the domestic literature. The development of neuroimaging techniques and a growing number of verified encephalocele cases promote the widespread use of surgery for treatment of intractable epilepsy. Congenital encephalocele should be considered in the differential diagnosis of intractable temporal epilepsy, and, if verified, surgical treatment is the method of choice in most cases.

    Rett syndrome is a neurodevelopmental genetic disorder, characterized by developmental delay, hand stereotypies, abnormal gait, and acquired microcephaly. Epilepsy is very common in Rett syndrome and can be medically intractable. It remains uncertain if a patient with epileptic drop attacks associated with this genetic disease can benefit from corpus callosotomy. We report an 8-year-old girl with Rett syndrome and medically intractable epileptic drop attacks who underwent endoscopic total corpus callosotomy without any complications that led to the successful elimination of her seizures. Total corpus callosotomy is a feasible treatment option for medically intractable epileptic drop attacks in Rett syndrome and should not be considered as a contraindication in this condition. This is the first reported case of corpus callosotomy in Rett syndrome.

    2010-03-01

    Palliative sedation (sedation to unconsciousness) as an option of last resort for intractable end-of-life distress has been the subject of ongoing discussion and debate as well as policy formulation. A particularly contentious issue has been whether some dying patients experience a form of intractable suffering not marked by physical symptoms that can reasonably be characterized as "existential" in nature and therefore not an acceptable indication for palliative sedation. Such is the position recently taken by the American Medical Association. In this essay we argue that such a stance reflects a fundamental misunderstanding of the nature of human suffering, particularly at the end of life, and may deprive some dying patients of an effective means of relieving their intractable terminal distress.

    The diagnosis rate of deep pelvic endometriosis is increasing. Endometrial stromal sarcoma (ESS) is a rare neoplasm. Extragenital ESS is an extremely uncommon event. Very few cases of extragenital ESS have been reported to date. The diagnosis of this entity is very difficult in some instances. Knowledge about its management is also limited. In this paper, we review the current literature on the clinical management, histology, immunohistochemistry, treatment and outcome of ESS arising in pelvic endometriosis. Copyright © 2012 S.

    Gerschman, J A

    2000-10-01

    Acute and chronic orofacial pain continues to be poorly understood and managed. The National Health and Medical Research Council of Australia (NHMRC) 1999 report on acute pain management promotes the development of evidence based clinical practice guidelines aimed at improving both the quality of health care and health outcomes in medical and dental practice in Australia. Nerve signals arising from sites of tissue or nerve injury lead to long term changes in the central nervous system and the amplification and persistence of pain. These nociceptor activity-induced neuronal changes known as central sensitization, have important clinical implications in the development of new approaches to the management of persistent pain. These findings and implications are discussed in relationship to poorly managed and understood conditions such as oral dysaesthesia, burning mouth syndrome, atypical facial pain/atypical odontalgia, peripheral nerve injury, deafferentation and phantom tooth syndrome.

    Full Text Available Abstract Extra nodal marginal zone B-cell lymphoma (EMZL of the conjunctiva typically arises in the marginal zone of mucosa-associated lymphoid tissue. The pathogenesis of conjunctival EMZL remains unknown. We describe an unusual case of EMZL arising from reactive lymphoid hyperplasia (RLH of the conjunctiva. A 35-year-old woman had fleshy salmon-pink conjunctival tumors in both eyes, oculus uterque (OU. Specimens from conjunctival tumors in the right eye, oculus dexter (OD, revealed a collection of small lymphoid cells in the stroma. Immunohistochemically, immunoglobulin (Ig light chain restriction was not detected. In contrast, diffuse atypical lymphoid cell infiltration was noted in the left eye, oculus sinister (OS, and positive for CD20, a marker for B cells OS. The tumors were histologically diagnosed as RLH OD, and EMZL OS. PCR analysis detected IgH gene rearrangement in the joining region (JH region OU. After 11 months, a re-biopsy specimen demonstrated EMZL based on compatible pathological and genetic findings OD, arising from RLH. This case suggests that even if the diagnosis of the conjunctival lymphoproliferative lesions is histologically benign, confirmation of the B-cell clonality by checking IgH gene rearrangement should be useful to predict the incidence of malignancy.

    The prevalence of epilepsy in sub-Saharan Africa is higher than in other parts of the world, but it is short of the effective measure on treating intractable epilepsy. Epilepsy surgery is not easy to be performed due to the high cost and demand of operational skills. The authors planned to perform ketogenic diet therapy for the children with intractable epilepsy in Ghana with regard to its low cost and simple procedure. The candidate is a 10-month-old girl with epilepsy with unknown etiology....

    It is widely known that sensation of the pain is derived from sensory-discriminative factor and emotional factor. Especially in chronic pain, emotional factors and psychosocial backgrounds are more likely to contribute for the patients' discomfort. The aim of this study is to investigate how emotional factor of pain participates in intractable pain. We employed functional MRI (fMRI) to compare the brain activations occurring in the orthopaedic neuropathic pain patients with allodynia and normal individuals in response to the visual virtual painful experience. During fMRI scanning, a video demonstrating an actual tactile stimulation of the palm and its imitation were shown to participants. In contrast to normal individuals, allodynia patients also displayed activation of the areas reflecting emotions: frontal lobe and anterior cingulate. These findings suggest that brain have important role in the development and maintaining of peripheral originated chronic painful condition. (author)

    Full Text Available Nevus sebaceous is a congenital, benign hamartomatous lesion, characterized by a yellowish to skin-colored, hairless, verrucous plaque on the head and neck region. In later life, a secondary tumor, either benign or malignant, can develop within nevus sebaceous. Eccrine poroma developing on nevus sebaceous is extremely rare. There are few case reports of eccrine poroma developing within nevus sebaceous. We report a case of a 30-year-old female who presented with a congenital, hairless, verrucous, yellowish lesion on the scalp and an erythematous nodule arising within the yellowish lesion for 8 months. Her clinical presentation and histopathological findings were compatible with nevus sebaceous and eccrine poroma.

    In discussing radiation from multiple point charges or magnetic dipoles, moving in circles or ellipses, a variety of Kapteyn series of the second kind arises. Some of the series have been known in closed form for a hundred years or more, others appear not to be available to analytic persuasion. This paper shows how 12 such generic series can be developed to produce either closed analytic expressions or integrals that are not analytically tractable. In addition, the method presented here may be of benefit when one has other Kapteyn series of the second kind to consider, thereby providing an additional reason to consider such series anew

    Full Text Available INTRODUCTION: The principal indication for surgical intervention in chronic pancreatitis is intractable pain. Depending upon the presence of dilated pancreatic ductal system, pancreatic duct drainage procedures and different kinds of pancreatic resections are applied. OBJECTIVE: The objective of the study was to show the most appropriate procedure to gain the most possible benefits in dependence of type of pathohistological process in chronic pancreatitis. METHOD: Our study included 58 patients with intractable pain caused by chronic pancreatitis of alcoholic genesis. The first group consisted of 30 patients with dilated pancreatic ductal system more than 10 mm. The second group involved 28 patients without dilated pancreatic ductal system. Pain relief, weight gain and glucose tolerance were monitored. RESULTS: All patients of Group I (30 underwent latero-lateral pancreaticojejunal - Puestow operation. 80% of patients had no pain after 6 month, 13.6% had rare pain and 2 patients, i.e. 6.4%, who continued to consume alcohol, had strong pain. Group II consisting of 28 patients was without dilated pancreatic ductal system. This group was subjected to various types of pancreatic resections. Whipple procedure (W was done in 6 patients, pylorus preserving Whipple (PPW in 7 cases, and duodenum preserving cephalic pancreatectomy (DPCP was performed in 15 patients. Generally, 89.2% of patients had no pain 6 month after the operation. An average weight gain was 1.9 kg in W group, 2.8 kg in PPW group and 4.1 kg in DPCP group. Insulin-dependent diabetes was recorded in 66.6% in W group, 57.1% in PPW group and 0% in DPCP group. CONCLUSION: According to our opinion, DPCP may be considered the procedure of choice for surgical treatment of pain in chronic pancreatitis in patients without dilatation of pancreas ductal system because of no serious postoperative metabolic consequences.

    Objective: To evaluate the efficacy of cuffed tracheostomy tube with inner cannula for the treatment of intractable aspiration after partial laryngectomy. Methods: From May 2010 to June 2015, 15 patients with intractable aspiration after partial laryngectomy of laryngeal and hypopharyngeal carcinoma were enrolled. Cuffed tracheostomy tube with inner cannula was used in the 15 patients for treatment of intractable aspiration. The patients and their family were trained to manage the cuffed tracheostomy tube with inner cannula and to eat since the 14th day after surgery. Cuff was initially inflated with 10 ml air and then deflated of 0.5 ml air every 2-3 days. Until the inflation of cuff was no longer required, the cuffed tracheostomy tube was replaced by metal tracheostomy tube. The patients' swallowing function and aspiration were evaluated 6 months after treatment. Results: The 15 cases with intractable aspiration were treated with cuffed tracheostomy tube with inner cannula and after 2-3 months, 14 of them replaced the cuffed tracheostomy tubes with inner cannula by metal tracheostomy tubes and recovered oral eating, and tracheostomy tubes were no longer required for 12 of 14 patients in following 3-6 months, showing a total decannulation rate of 80% in the patients with refractory aspiration. Conclusion: It was safe and effective to treat aspiration after laryngeal and hypopharyngeal surgery with cuffed tracheostomy tube with inner cannula.

    Intractable aspiration is a serious, often life-threatening condition due to its potential impact on pulmonary function. Aspiration requires therapeutic measures, starting with conservative management but often necessitating surgical treatment. The basic surgical principle is to separate the alimentary and respiratory tracts through a variety of procedures which, unfortunately, nearly all result in the loss of phonation, with the exception of total laryngectomy (TL) which includes the placement of an indwelling voice prosthesis. In this study, we present a modified laryngotracheal separation (LTS) technique that, we believe, offers multiple advantages compared to standard TL. After reviewing the medical records of 35 patients with intractable aspiration who have undergone LTS, we describe the surgical technique and present the postoperative result. In a second surgical procedure about two months following LTS, we aimed to achieve voice restoration by placement of an indwelling voice prosthesis. Intractable aspiration was successfully treated in all patients. Placement of an indwelling voice prosthesis during a second operation was successful in 15 patients, representing the largest reported cohort thus far. LTS is a reliable surgical technique to treat intractable aspiration, with restoration of oral intake, thereby improving the general condition and quality of life of these unfortunate patients. Furthermore, voice restoration can be achieved in selected patients, by placement of a voice prosthesis.

    To assess the frequency and clinical features of childhood-onset intractable epilepsy caused by the most common mutations in the POLG gene, which encodes the catalytic subunit of mitochondrial DNA polymerase gamma. Children presenting with nonsyndromic intractable epilepsy of unknown etiology but without documented liver dysfunction at presentation were eligible for this prospective, population-based study. Blood samples were analyzed for the three most common POLG mutations. If any of the three tested mutations were found, all the exons and the exon-intron boundaries of the POLG gene were sequenced. In addition, we retrospectively reviewed the notes of patients presenting with intractable epilepsy in which we had found POLG mutations. All available clinical data were collected by questionnaire and by reviewing the medical records. We analyzed 213 blood DNA samples from patients fulfilling the inclusion criteria of the prospective study. Among these, five patients (2.3%) were found with one of the three common POLG mutations as homozygous or compound heterozygous states. In addition, three patients were retrospectively identified. Seven of the eight patients had either raised cerebrospinal fluid (CSF) lactate (n = 3) or brain magnetic resonance imaging (MRI) changes (n = 4) at presentation with intractable epilepsy. Three patients later developed liver dysfunction, progressing to fatal liver failure in two without previous treatment with sodium valproate (VPA). Furthermore, it is worth mentioning that one patient presented first with an autism spectrum disorder before seizures emerged. Mutations in POLG are an important cause of early and juvenile onset nonsyndromic intractable epilepsy with highly variable associated manifestations including autistic features. This study emphasizes that genetic testing for POLG mutations in patients with nonsyndromic intractable epilepsies is very important for clinical diagnostics, genetic counseling, and treatment decisions

    2018-01-01

    Spinal cord injury arising during anaesthetic practice is a rare event, but one that carries a significant burden in terms of morbidity and mortality. In this article, we will review the pathophysiology of spinal cord injury. We will then discuss injuries relating to patient position, spinal cord hypoperfusion and neuraxial techniques. The most serious causes of spinal cord injury - vertebral canal haematoma, spinal epidural abscess, meningitis and adhesive arachnoiditis - will be discussed in turn. For each condition, we draw attention to practical, evidence-based measures clinicians can undertake to reduce their incidence, or mitigate their severity. Finally, we will discuss transient neurological symptoms. Some cases of spinal cord injury during anaesthesia can be ascribed to anaesthesia itself, arising as a direct consequence of its conduct. The injury to a spinal nerve root by inaccurate and/or incautious needling during spinal anaesthesia is an obvious example. But in many cases, spinal cord injury during anaesthesia is not caused by, related to, or even associated with, the conduct of the anaesthetic. Surgical factors, whether direct (e.g. spinal nerve root damage due to incorrect pedicle screw placement) or indirect (e.g. cord ischaemia following aortic surgery) are responsible for a significant proportion of spinal cord injuries that occur concurrently with the delivery of regional or general anaesthesia. © 2018 The Association of Anaesthetists of Great Britain and Ireland.

    Science.gov (United States)

    Romero-Reyes, Marcela; Uyanik, James M

    2014-01-01

    Some of the most prevalent and debilitating pain conditions arise from the structures innervated by the trigeminal system (head, face, masticatory musculature, temporomandibular joint and associated structures). Orofacial pain (OFP) can arise from different regions and etiologies. Temporomandibular disorders (TMD) are the most prevalent orofacial pain conditions for which patients seek treatment. Temporomandibular disorders include a number of clinical problems that involve the masticatory musculature, the temporomandibular joint (TMJ) or both. Trigeminal neuropathic pain conditions can arise from injury secondary to dental procedures, infection, neoplasias, or disease or dysfunction of the peripheral and/or central nervous system. Neurovascular disorders, such as primary headaches, can present as chronic orofacial pain, such as in the case of facial migraine, where the pain is localized in the second and third division of the trigeminal nerve. Together, these disorders of the trigeminal system impact the quality of life of the sufferer dramatically. A multidisciplinary pain management approach should be considered for the optimal treatment of orofacial pain disorders including both non-pharmacological and pharmacological modalities.

    Multicystic dysplastic kidney is a common cystic renal disease that often occurs in infancy. Recent studies demonstrate the possibility for spontaneous involution of a dysplastic kidney. In such cases, the prognosis is generally excellent and there is a very low incidence of complications. Complications associated with multicystic dysplastic kidney include pain, infection, hypertension, and neoplasia. Renal cell carcinomas are extremely rare in multicystic dysplastic kidneys. To our knowledge, no case report has described a radiologic finding of renal cell carcinoma arising from an involutional multicystic dysplastic kidney. We report a case of histopathologically validated cystic papillary renal cell carcinoma arising from an involutional multicystic dysplastic kidney and describe its sonographic and CT features.

    2009-01-01

    Pain is a cognitive evaluation. Its appearance in the new functional image systems is promising. Nocioceptive pain, usually acute or persistent, is useful to prevent animals from getting injured. Chronic pain is disease per se: It is due to a sensitisation phenomena and pain memory with an important relationship with emotions. Neuropathic pain is a neurological symptom due to a somatosensorial system dysfunction. In this case, axonal ectopic generation of impulses and synaptic hyperexcitability occurs. In persistent cases, sensitisation phenomenon and memory of pain appear together with neuropathic pain. Pain treatment should be physiopathologicaly orientated. Pain units, specialized in analgesic treatment and some invasive techniques, are usually competent in the treatment of nocioceptive pain. Neuropathic pain should have a neurologic diagnosis and treatment. But neurologist need to be more and more interested in the chronic pain related with memory and sensitisation: better knowledge of the cerebral mechanisms in this phenomenon can add to this pathology in our field.

  16. Voxel based morphometry of FLAIR MRI in children with intractable focal epilepsy: Implications for surgical intervention

    International Nuclear Information System (INIS)

    Riney, Catherine J.; Chong, William K.; Clark, Chris A.; Cross, J. Helen

    2012-01-01

    Purpose: Magnetic resonance imaging (MRI), in particular fluid-attenuated inversion-recovery (FLAIR), has transformed the delineation of structural brain pathology associated with focal epilepsy. However, to date there is no literature on voxel based morphometry (VBM) of FLAIR in children with epilepsy. The aim of this study was to explore the role of visual and VBM assessment of FLAIR in pre-operative investigation of children with intractable focal epilepsy. Methods: Children with intractable epilepsy due to focal cortical dysplasia (FCD) and children with intractable cryptogenic focal epilepsy (CFE) were investigated. FLAIR and T1-weighted MRI were acquired on a 1.5T MRI scanner (Siemens, Erlangen, Germany). VBM was performed using SPM5 (Wellcome Institute of Cognitive Neuroscience, London). Results: Eight children with FCD (M = 5, age 7.9–17.3 years) and 14 children with CFE (M = 8, 7.8–16.8 years) were enrolled. VBM of FLAIR detected 7/8 (88%) of FCD whilst VBM of T1-weighted MRI detected only 3/8 (38%) FCD. VBM of FLAIR detected abnormality in 4/14 children with CFE, in 2/14 (14%) the abnormality was concordant with other data on the epileptogenic zone and with visible abnormality on repeat visual inspection of MR data. VBM of T1-weighed MRI detected abnormality in 2/14 children with CFE, none of which correlated with visible abnormality. Discussion: This study highlights the important role that FLAIR imaging has in the pre-operative assessment of children with intractable epilepsy. VBM of FLAIR may provide important information allowing selection of children with intractable CFE who are likely to benefit from further neuroradiological or neurophysiological evaluation.

  17. Painful dressing changes for chronic wounds: assessment and management.

    Science.gov (United States)

    Solowiej, Kazia; Upton, Dominic

    Wound pain can arise from the wound itself, continuing wound treatment and anticipatory pain, which occurs in some patients as a consequence of negative experiences of care. Specifically, pain caused by the removal and application of dressings has been identified as a major contributor to wound pain, from both patient and health professional perspectives. This article reviews literature on the impact of pain at dressing change, and provides practical suggestions for assessment and management of pain during wound care.

  18. High grade angiosarcoma arising in fibroadenoma

    2011-01-01

    Primary angiosarcoma of the breast is a rare tumour that account for fewer than 0.05% of all malignant mammary tumours. Angiosarcoma may have an perfidious clinical onset. Radiologic findings are often nonspecific and may appear completely normal in one-third of cases with primary angiosarcoma. The prognosis is usually poor because of the high rates of local recurrence and early development of metastases. Aggressive surgical resection is the mainstay of treatment. The role of adjuvant therapy has not yet been well established. Here we present a case of a 53 year old, postmenopausal women with primary angiosarcoma arising in fibroadenoma. To our knowledge, this is the first case described in the literature to date. PMID:22185665

  19. Radioisotopes: problems of responsibility arising from medicine

    1978-09-01

    Radioisotopes have brought about great progress in the battle against illnesses of mainly tumoral origin, whether in diagnosis (nuclear medicine) or in treatment (medical radiotherapy). They are important enough therefore to warrant investigation. Such a study is attempted here, with special emphasis, at a time when medical responsibility proceedings are being taken more and more often on the medicolegal problems arising from their medical use. It is hoped that this study on medical responsibility in the use of radioisotopes will have shown: that the use of radioisotopes for either diagnosis or therapy constitutes a major banch of medicine; that this importance implies an awareness by the practitioner of a vast responsibility, especially in law where legislation to ensure protection as strict as in the field of ionizing radiations is lacking. The civil responsibility of doctors who use radioisotopes remains to be defined, since for want of adequate jurisprudence we are reduced to hypotheses based on general principles [fr

    Cancer arising from a female urethral diverticulum is rare, and because of its rarity, a review of the medical literature reveals significant nonuniformity in its management. We report an additional 2 cases of this disease, one of which has an even rarer feature of being mucin-producing. The management of our 2 cases is presented in detail and in line with the management of female urethral cancer. From our extensive literature search, diverticulectomy alone showed poor results with the highest rate of recurrence (67%). Extensive surgery, either in the form of cystourethrectomy or anterior exenteration, offered results comparable with those of combined therapy (diverticulectomy and full course of irradiation for early cases; preoperative irradiation followed by cystourethrectomy for late cases). Individualization of radiation treatment and cooperative effort between urologist and radiation oncologist are essential if best results are to be achieved

  1. Periorbital nodular fasciitis arising during pregnancy

    Full Text Available Nodular fasciitis (NF is a benign proliferation of fibroblasts and myofibroblasts that rarely occurs in the periorbital region. We report what we believe to be the first case of periorbital NF associated with pregnancy. A case of intravascular fasciitis, a NF variant, has been reported during pregnancy, but it was not located in the periorbital region. A weak presence of estrogen receptors has been reported in NF. This may make it more susceptible to the hormone-related changes during pregnancy and contribute to the development of the lesion by stimulating fibroblasts and smooth muscle cell types. Although rare, NF should be considered in the differential diagnosis of periorbital soft-tissue masses arising during pregnancy.

    The microbial world displays an immense taxonomic diversity. This diversity is manifested also in a multitude of metabolic pathways that can utilise different substrates and produce different products. Here, we propose that these observations directly link to thermodynamic constraints that inherently arise from the metabolic basis of microbial growth. We show that thermodynamic constraints can enable coexistence of microbes that utilise the same substrate but produce different end products. We find that this thermodynamics-driven emergence of diversity is most relevant for metabolic conversions with low free energy as seen for example under anaerobic conditions, where population dynamics is governed by thermodynamic effects rather than kinetic factors such as substrate uptake rates. These findings provide a general understanding of the microbial diversity based on the first principles of thermodynamics. As such they provide a thermodynamics-based framework for explaining the observed microbial diversity in different natural and synthetic environments. PMID:27035705

    Cancer pain is a devastating condition. Pain in the orofacial region, may be present as the single symptom of cancer or as a symptom of cancer in its later stages. This manuscript revises in a comprehensive manner the content of the conference entitled "Orofacial Pain and Cancer" (Dolor Orofacial y Cancer) given at the VI Simposio International "Advances in Oral Cancer" on the 22 July, 2016 in San Sebastioan-Donostia, Spain. We have reviewed (pubmed-medline) from the most relevant literature including reviews, systematic reviews and clinical cases, the significant and evidence-based mechanisms and mediators of cancer-associated facial pain, the diverse types of cancers that can be present in the craniofacial region locally or from distant sites that can refer to the orofacial region, cancer therapy that may induce pain in the orofacial region as well as discussed some of the new advancements in cancer pain therapy. There is still a lack of understanding of cancer pain pathophysiology since depends of the intrinsic heterogeneity, type and anatomic location that the cancer may present, making more challenging the creation of better therapeutic options. Orofacial pain can arise from regional or distant tumor effects or as a consequence of cancer therapy. The clinician needs to be aware that the pain may present the characteristics of any other orofacial pain disorder so a careful differential diagnosis needs to be given. Cancer pain diagnosis is made by exclusion and only can be reached after a thorough medical history, and all the common etiologies have been carefully investigated and ruled out. The current management tools are not optimal but there is hope for new, safer and effective therapies coming in the next years.

    Presenting a rare complication of an odontogenic infection extending to the orbit. A 45-year-old male patient reported with periorbital swelling of eyelids, of the left eye, foul smelling nasal discharge and a pus draining sinus on the left lower eyelid area. The patient gave history of pain in the left upper first molar tooth 1 week back. His intraoral examination showed poor oral hygiene with tenderness on percussion on the left maxillary first molar. Investigations showed possible extension of infection from left maxillary molar root to maxillary sinus and to the orbital floor. A case of periapical infection of a maxillary left molar resulting in an orbital abscess is presented. Identification of odontogenic source of infections, institution of drainage, removal of offending teeth and appropriate antimicrobial therapy are mandatory in preventing loss of vision and cerebral extensions. The pathways of spread of the infection, treatment aspects, are discussed and complications are reviewed.

    We report MR imaging findings of a rare case of endocervical mucinous borderline tumor (MBT) involving the cul-de-sac and left fallopian tube arising from extensive pelvic endometriosis with pathologic correlation in a 35-year-old woman presented with vague pelvic pain. Endocervical MBT is a type of endometriosis-associated carcinoma. Imaging findings of endocervical MBT are unilocular or oligolocular cystic lesions with enhancing mural nodules, which are different from those of the more common intestinal type MBT.

    Full Text Available Abstract Chronic neck pain is widely prevalent and a common source of disability in the working-age population. Etiology of chronic neck pain includes neck sprain, mechanical or muscular neck pain, myofascial pain syndrome, postural neck pain as well as pain due to degenerative changes. We report the case of a 42 year old secretary, complaining about a longer history of neck pain and limited movement of the cervical spine. Surprisingly, the adequate radiologic examination revealed a bilateral ossification of the stylohyoid ligament complex. Her symptoms remained intractable from conservative treatment consisting of anti-inflammatory medication as well as physical therapy. Hence the patient was admitted to surgical resection of the ossified stylohyoid ligament complex. Afterwards she was free of any complaints and went back to work. Therefore, ossification of the stylohyoid ligament complex causing severe neck pain and movement disorder should be regarded as a rare differential diagnosis of occupational related neck pain.

    Eighteen patients with chemodectomas arising in temporal bone structures were evaluated and treated at the University of Florida. Seventeen patients have each been followed a minimum of 3 years. Patients were retrospectively staged as having ''local'' or ''advanced'' disease, depending on the presence or absence of bone destruction and/or cranial nerve involvement. Fourteen of the patients received radiation therapy as all or part of their therapy; 6 patients were treated with radiation therapy alone, 3 patients were irradiated immediately postoperatively for residual disease, and 5 patients had radiation therapy for recurrence after operation. They were treated with cobalt-60 radiation with doses ranging from 3760 to 5640 rad. All irradiated patients demonstrated evidence of tumor regression, and none have had tumor recurrence with followup of 3-12 years. Of the 8 patients with cranial nerve paralysis prior to therapy, 5 had return of function of 1 or more cranial nerves. One of 6 patients treated initially with radiation therapy had a complication, while 6 of 8 patients irradiated postoperatively had complications. None of the complications were fatal. Three patients treated by operation for early disease limited to the hypotympanum had the disease controlled for 11-12 years. Guidelines for the selection of initial therapy are discussed

    Our aim was to present the results from a retrospective study of 7 cases of squamous cell carcinoma arising from chronic osteomyelitis. We treated seven cases of chronic osteomyelitis related squamous cell carcinoma between 1993 and 2005. The patients had an average age of 54.5 (range: 38-71) years, with a male predominance (6 men, 1 woman). We analyzed the time up to cancerization, the localization and histopathological type of the carcinoma, and the type and result of the treatment. The mean time between the occurrence of the skin lesions and the diagnosis of malignant degeneration was 24.5 (range: 9 to 40) years. The carcinoma resulted from tibia osteomyelitis in 4 cases, femur osteomyelitis in 2 cases and humerus osteomyelitis in one. The pathological examination showed five cases of a well differentiated squamous cell carcinoma with bone invasion, and two cases of invasive squamous cell carcinoma. The treatment consisted of amputation in all but one patient, who refused the amputation. The six amputee patients did not show local recurrence or metastatic dissemination over a period of five years. Amputation appears to be an effective treatment method in squamous carcinoma secondary to chronic osteomyelitis.

    Cutaneous leiomyosarcoma (CLM) is a very rare smooth muscle tumour that accounts for about 2-3% of all superficial soft tissue sarcomas. Although the development of various malignancies in scar tissue is well known, we report the first case of a CLM developing in a small pox scar. A 66-year-old man presented with a painless, slow-growing lump in a small pox scar on his left shoulder. Histological biopsies showed the lesion to be a primary, well-differentiated cutaneous leiomyosarcoma. A CT scan of the thorax was conducted, which showed no signs of metastases. The complete lesion was then surgically excised, and histopathological examination revealed a radically excised cutaneous type leiomyosarcoma After 13 months' review the patient was doing well with no evidence of tumour recurrence. This is the first report of a CLM arising in a small pox scar. Although the extended time interval between scarring and malignant changes makes it difficult to advise strict follow-up for patients with small pox scars, one should be aware that atypical changes and/or symptoms occurring in a small pox scar could potentially mean malignant transformation.

    1986-01-01

    The Nuclear Safety and Health Protection Directorate (DISP) of ENEA has organized a structure of officers and technicians on call whenever an accident related to the activity of ENEA-DISP should occur. The most frequent events arise from natural misfortunes, crime, and deficiencies in public services. As regards technical operations such as measurements, removals, decontaminations and transport, DISP requests utilization of the different structures and equipment available to ENEA research centres and, in particular and most frequently, of the Safety and Radioprotection Division of the main ENEA centre: the Casaccia Research Centre. The technicians of this division are always available via telephone or radio, with the firm duty to be present within one hour from the call. The co-operation between these two structures enables timely and efficient intervention in many circumstances so that population and environmental risks can be avoided. Typical accidental situations are earthquakes, adverse atmospheric events, landslides, collapses, railway and road accidents, lost sources discovery, and seizure of illegally detained sources by judicial power. The paper briefly describes some of the situations which have occurred, and the actions carried out to recover sources and to re-establish safe environmental conditions. (author)

  14. Chemical hazards arising from shale gas extraction

    Full Text Available The development of the shale industry is gaining momentum and hence the analysis of chemical hazards to the environment and health of the local population is extremely timely and important. Chemical hazards are created during the exploitation of all minerals, but in the case of shale gas production, there is much more uncertainty as regards to the effects of new technologies application. American experience suggests the increasing risk of environmental contamination, mainly groundwater. The greatest concern is the incomplete knowledge of the composition of fluids used for fracturing shale rock and unpredictability of long-term effects of hydraulic fracturing for the environment and health of residents. High population density in the old continent causes the problem of chemical hazards which is much larger than in the USA. Despite the growing public discontent data on this subject are limited. First of all, there is no epidemiological studies to assess the relationship between risk factors, such as air and water pollution, and health effects in populations living in close proximity to gas wells. The aim of this article is to identify and discuss existing concepts on the sources of environmental contamination, an indication of the environment elements under pressure and potential health risks arising from shale gas extraction.

  15. An organism arises from every nucleus.

    Full Text Available The fact that, cloning using somatic cell nuclear transfer (SCNT method has been performed, opened new horizons for cloning, and changed the way of our understanding and approach to cell and nucleus. The progress in cloning technology, brought the anticipation of the ability to clone an organism from each somatic cell nucleus. Therefore, the 'Cell Theory' is about to take the additional statement as "An organism arises from every nucleus". The development of gene targeting procedures which can be applied with SCNT, showed us that it may be possible to obtain different versions of the original genetic constitution of a cell. Because of this opportunity which is provided by SCNT, in reproductive cloning, it would be possible to clone enhanced organisms which can adapt to different environmental conditions and survive. Furthermore, regaining the genetic characteristics of ancestors or reverse herediter variations would be possible. On the other hand, in therapeutic cloning, more precise and easily obtainable alternatives for cell replacement therapy could be presented. However, while producing healthier or different organisms from a nucleus, it is hard to foresee the side effects influencing natural processes in long term is rather difficult.

  17. How diagnostic tests help to disentangle the mechanisms underlying neuropathic pain symptoms in painful neuropathies.

    Science.gov (United States)

    Truini, Andrea; Cruccu, Giorgio

    2016-02-01

    Neuropathic pain, ie, pain arising directly from a lesion or disease affecting the somatosensory afferent pathway, manifests with various symptoms, the commonest being ongoing burning pain, electrical shock-like sensations, and dynamic mechanical allodynia. Reliable insights into the mechanisms underlying neuropathic pain symptoms come from diagnostic tests documenting and quantifying somatosensory afferent pathway damage in patients with painful neuropathies. Neurophysiological investigation and skin biopsy studies suggest that ongoing burning pain primarily reflects spontaneous activity in nociceptive-fiber pathways. Electrical shock-like sensations presumably arise from high-frequency ectopic bursts generated in demyelinated, nonnociceptive, Aβ fibers. Although the mechanisms underlying dynamic mechanical allodynia remain debatable, normally innocuous stimuli might cause pain by activating spared and sensitized nociceptive afferents. Extending the mechanistic approach to neuropathic pain symptoms might advance targeted therapy for the individual patient and improve testing for new drugs.

    This Master s Thesis develops the concept of identity conflict on the basis of needs- and identity-based approaches to conflict resolution. These various theoretical perspectives share the assumption that identity conflicts make up a particularly intractable type of conflict that is not amendable to conventional methods of conflict management. The concept of identity conflict incorporates several key assumptions from the needs- and identity-based approaches to conflict resolution. First it as...

    The importance of hope in promoting conciliatory attitudes has been asserted in the field of conflict resolution. However, little is known about conditions inducing hope, especially in intractable conflicts, where reference to the outgroup may backfire. In the current research, five studies yielded convergent support for the hypothesis that hope for peace stems from a general perception of the world as changing. In Study 1, coders observed associations between belief in a changing world, hope...

    This paper describes the 1995 Hanshin-Awaji Earthquake experience of the local public health nurses. The purpose of the study was to identify problems regarding assistance of intractable neurological patients at home during and after the earthquake and to discuss ways to improve future local disaster responses by public health nurses for those patients. Approximately 2 hours of a group interview of public health nurses from 2 public health centers in Kobe City was conducted in August, 1996. Interview data was collected via audio-tape and transcribed. The data was organized according to phases of the earthquake. The acute phase of the earthquake disaster ended within 72 hours. The data was then analyzed to identify problems in assisting intractable neurological home patients in order to discuss disaster responses by public health nurses. There was a delay in confirming the safety of and providing needed assistance for intractable neurological patients at home by public health nurses. During the first 3 days after the earthquake, the majority of public health nurses were unable to commute to work due to the shutdown of transportation systems. In addition, nurses, who were able to come to work, were preoccupied with treating earthquake casualties and distributing medical supplies. Other factors associated with the delay included the following: lack of a registration list for intractable neurological patients at home; lack of close contacts between public health nurses and patients, and between public health nurses and patient support groups; and sparing nurses for guiding volunteers and for coordinating between shelters and hospitals. Measures to improve future disaster responses are as follows: a) teaching patients and their families how to safeguard against disaster; b) preparing registration lists; c) establishing support networks and cooperating with network members; and d) upon disaster, assigning some nurses to assess the needs of patients.

    Children with intractable functional constipation (FC) may eventually require surgery. However, guidelines regarding the surgical management of children with intractable FC are lacking. The aim of this study was to describe the surgical management of FC in children. A retrospective chart review was performed of children with FC (according to the Rome III criteria) who underwent ileostomy, colostomy or (sub)total colectomy at a tertiary hospital. Treatment success was defined as no longer fulfilling the Rome III-FC-criteria or having a functional ostomy. In addition, a self-developed questionnaire was administered to parents by telephone to assess postsurgical satisfaction (yes-no question and rated on a scale of 1-10). Thirty-seven patients (68% female) were included; median age at first surgery was 12 years (range 1.6-17.6). The initial surgical procedure consisted of ileostomy (n=21), colostomy (n=10), sigmoid resection (n=5) and subtotal colectomy (n=1). Success criteria were fulfilled by 85% of the patients. Postsurgical satisfaction of parents was 91% with a median postoperative satisfaction score of 8 (range 2-10), and 97% would opt for the same procedure(s) if necessary. Thirty patients (81%) experienced stoma problems, with 12 patients (32%) requiring stoma-revisions. Other complications occurred in 16 patients (43%). Surgery can improve symptoms in children with intractable FC. Despite morbidity and complications, parental satisfaction is high. Prospective, high-quality research is necessary to develop guidelines for the diagnostic work-up and surgical management in children with intractable FC. © 2016 John Wiley & Sons Ltd.

    Full Text Available Struma ovarii, which is classified as benign or malignant, is a mature ovarian teratoma consisting mainly of the thyroid tissue. Here, we present the case of malign struma ovarii in a patient with right adnexal mass. In a 53-year-old female, who was referred to our hospital with pelvic pain, abdominopelvic imaging revealed a cystic lesion measuring 15x14 cm in diameter in the right adnexa. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. Microscopic evaluation revealed a 1.5x1x0.5 cm papillary carcinoma focus in frozen sections of the mural nodule which was observed inside the cyst. Following the surgical procedure, the patient’s TSH levels were kept low by thyroxine treatment, and it was decided to follow the patient by annual measurement of thyroglobulin levels and pelvic imaging. There is not a common consensus on optimal treatment of malignant struma ovarii. Treatment options depend on cases or case series. Turk Jem 2015; 19: 112-114

    Full Text Available A 35-year-old female presented with 13-year history of unilateral recurrent nasal mass, epistaxis and facial pain. Nasal examination revealed a pale glistening mass in the right nasal cavity. On probing, mass was insensitive to touch and bled on handling. Computed tomographic scan showed a mass filling the right nasal cavity, ipsilateral maxillary and ethmoid sinuses. Diagnosis of pansinusitis polyposis was made.Transnasal endoscopy-assisted excision of the mass was done, and the diagnosis of olfactory neuroblastoma was established by histopathology and confirmed by immunohistochemistry. The mass was classified as a Kadish stage B tumor. Further intervention including medial maxillectomyand ethmoidectomy, and complete endoscopic-resection of the tumor from cribriform plate was done via lateral rhinotomy approach. The tumor was found adhered to the lateral wall-the middle meatus and was easily peeled away from the cribriform plate and ethmoids. Patient was referred for radiotherapy. No evidence of loco-regional recurrence or systemic metastasis observed at 10-month follow-up.

    To determine the efficacy, side effects and feasibility of Medium chain triglyceride (MCT) ketogenic diet (KD) in Thai children with intractable epilepsy. Children with intractable epilepsy were recruited. Baseline seizure frequency was recorded over 4 weeks before starting MCT KD. Average seizure frequency was assessed at 1 month and 3 months, compared to the baseline using Wilcoxon Signed Rank Test. Side effects and feasibility were also assessed by blood tests and an interview. Sixteen subjects were recruited with mean seizure frequency of 0.35-52.5 per day. After treatment, there was a significant reduction in seizure frequency, ranging from 12% to 100% (p = 0.002 at 1 month, and 0.001 at 3 months). 64.3% of the subjects achieved more than 50% seizure reduction at 3 months and 28.6% of the patients were seizure-free. Common adverse effects were initial weight loss (37.5%) and nausea (25%). 87.5% of subjects and parents were satisfied with the MCT KD with 2 cases dropping-out due to diarrhea and non-compliance. MCT ketogenic diet is effective and feasible in Thai children with intractable epilepsy. Despite modification against Asian culinary culture, the tolerability and maintenance rate was still satisfactory. A larger study is required.

    The prevalence of epilepsy in sub-Saharan Africa is higher than in other parts of the world, but it is short of the effective measure on treating intractable epilepsy. Epilepsy surgery is not easy to be performed due to the high cost and demand of operational skills. The authors planned to perform ketogenic diet therapy for the children with intractable epilepsy in Ghana with regard to its low cost and simple procedure. The candidate is a 10-month-old girl with epilepsy with unknown etiology. Her seizures couldn't be controlled by more than 3 antiepileptic drugs. Her development delayed severely due to frequent seizures. The authors successfully applied ketogenic diet for her. Her seizures were completely controlled after 2 weeks' therapy. Her mental condition was improved after that. The authors get much experience from this case for further developing ketogenic diet in Africa. This is the first report that ketogenic diet was applied to control intractable epilepsy in West Africa.

    Intractable epilepsies, that is, seizure disorders that do not respond to currently available therapies, are difficult, often tragic, neurological disorders. Na+ channelopathies have been implicated in some intractable epilepsies, including Dravet syndrome (Dravet 1978), but little progress has been forthcoming in therapeutics. Here we examine a Drosophila model for intractable epilepsy, the Na+ channel gain-of-function mutant parabss1 that resembles Dravet syndrome in some aspects (parker et al. 2011a). In particular, we identify second-site mutations that interact with parabss1, seizure enhancers, and seizure suppressors. We describe one seizure-enhancer mutation named charlatan (chn). The chn gene normally encodes an Neuron-Restrictive Silencer Factor/RE1-Silencing Transcription factor transcriptional repressor of neuronal-specific genes. We identify a second-site seizure-suppressor mutation, gilgamesh (gish), that reduces the severity of several seizure-like phenotypes of parabss1/+ heterozygotes. The gish gene normally encodes the Drosophila ortholog of casein kinase CK1g3, a member of the CK1 family of serine-threonine kinases. We suggest that CK1g3 is an unexpected but promising new target for seizure therapeutics. PMID:23797108

    Functional magnetic resonance imaging (fMRI), a non-invasive technique with high spatial resolution and blood oxygen level dependent (BOLD) contrast, has been applied to localize and map cognitive functions in the clinical condition of chronic intractable epilepsy. fMRI was used to map the language and memory network in patients of chronic intractable epilepsy pre- and post-surgery. After obtaining approval from the institutional ethics committee, six patients with intractable epilepsy with an equal number of age-matched controls were recruited in the study. A 1.5 T MR scanner with 12-channel head coil, integrated with audio-visual fMRI accessories was used. Echo planar imaging sequence was used for BOLD studies. There were two sessions in TLE (pre- and post-surgery). In TLE patients, BOLD activation increased post-surgery in comparison of pre-surgery in inferior frontal gyrus (IFG), middle frontal gyrus (MFG), and superior temporal gyrus (STG), during semantic lexical, judgment, comprehension, and semantic memory tasks. Functional MRI is useful to study the basic concepts related to language and memory lateralization in TLE and guide surgeons for preservation of important brain areas during ATLR. This will help in understanding future directions for the diagnosis and treatment of such disease

    Transarterial embolization (TAE) appears to be a safe and effective treatment for patients with intractable epistaxis, despite different etiologies or angiography findings. Idiopathic epistaxis is prone to present with negative angiographic findings. To retrospectively evaluate the safety and effectiveness of TAE for intractable epistaxis, and focus on the factors of etiology and angiographic findings. From March 2008 to December 2014, the data of 43 patients with intractable bleeding undergoing TAE were reviewed. The outcomes of interventional therapy were assessed according to different etiology (malignant or benign disease) and angiographic finding (positive or negative angiogram). Positive angiographic findings were found in 11 of 12 cases with malignant diseases and 22 of 31 cases with benign diseases, respectively (p = 0.237). Among the 10 cases with negative angiographic findings, the negative angiography rate of idiopathic epistaxis was higher than that of epistaxis with definite etiology (p = 0.003). Bleeding was controlled successfully in all of the 43 patients after embolization. During the mean follow-up period of 24.0 ± 16.7 months, five patients relapsed. No significant difference was found in recurrence rates between malignant and benign diseases or between positive and negative angiography (p = 0.241, p = 0.704, respectively).

    Objective: To evaluate the clinical value of internal carotid artery occlusion in treatment of intractable epistaxis caused by carotid artery siphon traumatic lesions. Methods: A total of 37 patients with intractable epistaxis caused by traumatic carotid artery siphon pseudoaneurysm or carotid cavernous fistula were retrospectively analyzed. All the patients underwent embolization from October 1998 to June 2010, including 34 men and 3 women with the age ranged from 25 to 65 years and a average of 40 years. Only lesions were occluded in 12 cases without involving the internal carotid artery, while occlusions of internal carotid artery were performed in the rest 25 cases. Results: Thirty-six patients were cured without recurrent hemorrhage after embolization. Only 1 patient with carotid artery occlusion died 48 hours after operation. Conclusion: For patients with carotid arterial intractable epistaxis, if the elimination of the lesions is not applicable and the collateral circulation of Willis ring has a good compensation, the use of detachable balloon or coil occlusion of ipsilateral internal carotid artery is a quick and easy method to save patients' lives.

    Full Text Available Abstract Malignant peripheral nerve sheath tumors (MPNSTs are rare soft tissue tumors that arise from a peripheral nerve or exhibit nerve sheath differentiation. Most of these tumors arise on the trunk, extremities, or head and neck regions; they are very rarely located in the abdominal cavity. The patient was a 71-year-old man who was referred to our hospital for a mass and pain in the right lower abdomen. Abdominal computed tomography revealed a large (9 × 9 cm, well-circumscribed, lobulated, heterogeneously enhanced mass in the pelvis. Exploratory laparotomy revealed a large mass in the greater omentum, and the tumor was completely excised. Histopathological analysis revealed that the tumor was composed of spindle cells with high mitotic activity. On staining the tumor, positive results were obtained for S-100 but negative results were obtained for c-kit, cluster of differentiation (CD34, α-smooth muscle actin, and desmin. These findings strongly supported a diagnosis of MPNST primarily arising from the greater omentum. To the best of our knowledge, this is the first reported case of an MPNST arising from the greater omentum. In this report, we have described the case of a patient with an MPNST arising from the greater omentum and have discussed the clinical characteristics and management of MPNSTs.

    1996-01-01

    Full Text Available Thalamic or central pain states are generally regarded as rare in stroke, occurring in fewer than 2% of patients. However, a recent study suggests that they may be more common, occurring in up to 8% of unselected stroke patients. Cerebrovascular lesions leading to central pain states do not necessarily involve the thalamus, but can occur following lower brainstem and suprathalamic lesions. Damage to the spinothalamocortical tract appears to be a prerequisite to the development of central poststroke pain (CPSP. Development of CPSP is likely related to denervation hyperexcitability of third or fourth order, thalamic or cortical neurons. Central pain is often described as a 'burning' sensation in association with an unpleasant association of tingling, pins and needles, or numbness. Spontaneous or evoked dysesthesia and allodynia/hyperalgesia are common. Central or thalamic pain is generally intractable to most therapeutic interventions. One case is presented to illustrate the typical clinical presentation of thalamic pain states and the difficulties in treating this pain.

    The clinical diagnostic dilemma of low back pain that is associated with lower limb pain is very common. In relation to back pain that radiates to the leg, the International Association for the Study of Pain (IASP) states: "Pain in the lower limb should be described specifically as either referred pain or radicular pain. In cases of doubt no implication should be made and the pain should be described as pain in the lower limb." Bogduks' editorial in the journal PAIN (2009) helps us to differentiate and define the terms somatic referred pain, radicular pain, and radiculopathy. In addition, there are other pathologies distal to the nerve root that could be relevant to patients with back pain and leg pain such as plexus and peripheral nerve involvement. Hence, the diagnosis of back pain with leg pain can still be challenging. In this article, we present a patient with back and leg pain. The patient appears to have a radicular pain syndrome, but has no neurological impairment and shows signs of myofascial involvement. Is there a single diagnosis or indeed two overlapping syndromes? The scope of our article encompasses the common diagnostic possibilities for this type of patient. A discussion of treatment is beyond the scope of this article and depends on the final diagnosis/diagnoses made.

  7. NGF/TrkA Signaling as a Therapeutic Target for Pain.

    2016-02-01

    Nerve growth factor (NGF) was first discovered approximately 60 years ago by Rita Levi-Montalcini as a protein that induces the growth of nerves. It is now known that NGF is also associated with Alzheimer's disease and intractable pain, and hence, it, along with its high-affinity receptor, tropomyosin receptor kinase (Trk) A, is considered to be 1 of the new targets for therapies being developed to treat these diseases. Anti-NGF antibody and TrkA inhibitors are known drugs that suppress NGF/TrkA signaling, and many drugs of these classes have been developed thus far. Interestingly, local anesthetics also possess TrkA inhibitory effects. This manuscript describes the development of an analgesic that suppresses NGF/TrkA signaling, which is anticipated to be 1 of the new methods to treat intractable pain. © 2015 World Institute of Pain.

  8. Antinociceptive Effect of Intrathecal Microencapsulated Human Pheochromocytoma Cell in a Rat Model of Bone Cancer Pain

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available Human pheochromocytoma cells, which are demonstrated to contain and release met-enkephalin and norepinephrine, may be a promising resource for cell therapy in cancer-induced intractable pain. Intrathecal injection of alginate-poly (l lysine-alginate (APA microencapsulated human pheochromocytoma cells leads to antinociceptive effect in a rat model of bone cancer pain, and this effect was blocked by opioid antagonist naloxone and alpha 2-adrenergic antagonist rauwolscine. Neurochemical changes of cerebrospinal fluid are in accordance with the analgesic responses. Taken together, these data support that human pheochromocytoma cell implant-induced antinociception was mediated by met-enkephalin and norepinephrine secreted from the cell implants and acting at spinal receptors. Spinal implantation of microencapsulated human pheochromocytoma cells may provide an alternative approach for the therapy of chronic intractable pain.

    In the very elderly, their general condition and poor compliance with drug regimens can render the treatment of low back pain (LBP) difficult. We report the effectiveness of a less-invasive treatment for intractable LBP from superior cluneal nerve entrapment neuropathy (SCN-EN) and gluteus medius muscle (GMeM) pain. Between April 2013 and March 2015, we treated 17 consecutive elders with LBP, buttock pain, and leg pain. They were 4 men and 13 women ranging in age from 85 to 91 years (mean 86.6 years). We carefully ascertained that their symptoms were attributable to SCN-EN and GMeM pain. The median follow-up period was 21.5 ± 12.2 months (range 2-35 months). SCN-EN was diagnosed in 15 patients (28 sites) and GMeM pain in 14 (27 sites). In 5 patients, we obtained symptom control by local block (Numerical Rating Scale for LBP: declined from 7.8 to 0.8 [P < 0.05], Roland-Morris Disability Questionnaire score: declined from 16.5 to 5.2). The other 12 were operated under local anesthesia (SCN neurolysis, GMeM decompression). As 3 patients reported the persistence of leg pain postoperatively, they subsequently underwent peroneal nerve neurolysis and surgery for tarsal tunnel syndrome. These treatments resulted in significantly symptom abatement (Numerical Rating Scale: from 8.2 to 1.7, Roland-Morris Disability Questionnaire score: from 12.8 to 8.6; P < 0.05). Even very old patients with intractable LBP, buttock pain, and leg pain due to SCN-EN or GMeM pain can be treated successfully by peripheral block and less-invasive surgery under local anesthesia.

    This study aimed to determine the impact of a ketogenic diet (KD) on neurobehavioral development when used to treat children with intractable epilepsy, confirming the efficacy of the KD, as well as the correlation between early electroencephalography (EEG) changes in the early stage with treatment efficacy. We enrolled 42 children who were starting treatment for intractable epilepsy with the classic KD protocol. The total development quotient as well as the development quotients for adaptability, gross motor movements, fine motor movements, language, and individual-social interaction on the Gesell developmental scales were assessed before and after 3, 6, 12, and 18 months of KD treatment. The efficacy assessment was based on changes in seizure frequency after KD as recorded by the parents. We conducted 24-h video-EEG before and after 1 month of KD treatment. Developmental quotients of five energy regions in the Gesell developmental scales assessment were used to compare adaptability (P1=0.000), gross motor movements (P2=0.010), and fine motor movements (P3=0.000); the results showed significant differences. After KD treatment at different time points, 69.0%, 54.8%, 40.5%, and 33.3% patients, respectively, achieved a ≥50% reduction in seizure frequency. The reduction of epileptiform discharges in the awake state after 1 month of KD treatment correlated with the efficacy after 3 months of KD treatment. Ketogenic diet treatment tends to be associated with improved neurobehavioral development, and more significant improvement can be obtained with prolonged treatment. The KD is safe and effective in treating children with intractable epilepsy. Early EEG changes correlate with clinical efficacy, to a certain degree. Copyright © 2015 The Authors.

    Purpose To measure the accuracy of resting-state functional magnetic resonance (MR) imaging in determining hemispheric language dominance in patients with medically intractable focal epilepsies against the results of an intracarotid amobarbital procedure (IAP). Materials and Methods This study was approved by the institutional review board, and all subjects gave signed informed consent. Data in 23 patients with medically intractable focal epilepsy were retrospectively analyzed. All 23 patients were candidates for epilepsy surgery and underwent both IAP and resting-state functional MR imaging as part of presurgical evaluation. Language dominance was determined from functional MR imaging data by calculating a laterality index (LI) after using independent component analysis. The accuracy of this method was assessed against that of IAP by using a variety of thresholds. Sensitivity and specificity were calculated by using leave-one-out cross validation. Spatial maps of language components were qualitatively compared among each hemispheric language dominance group. Results Measurement of hemispheric language dominance with resting-state functional MR imaging was highly concordant with IAP results, with up to 96% (22 of 23) accuracy, 96% (22 of 23) sensitivity, and 96% (22 of 23) specificity. Composite language component maps in patients with typical language laterality consistently included classic language areas such as the inferior frontal gyrus, the posterior superior temporal gyrus, and the inferior parietal lobule, while those of patients with atypical language laterality also included non-classical language areas such as the superior and middle frontal gyri, the insula, and the occipital cortex. Conclusion Resting-state functional MR imaging can be used to measure language laterality in patients with medically intractable focal epilepsy.

    To investigate the clinical features and management of intractable deep-seated epistaxis. Clinical data were analyzed retrospectively in 195 patients with intractable deep-seated epistaxis treated in Affiliated Hospital of Qingdao College between June 2008 and June 2014. The analyses included common risk factors, bleeding sites, treatments and therapeutic effects. SPSS 17.0 software was used to analyze the data. There were 162 males and 33 females, aged from 15 to 88 years old (mean 52 ± 16 years). One hundred and eighty-seven cases (95.9%) were unilateral and 8 cases (4.1%) were bilateral. One hundred and twenty-six cases (64.6%) had the history of hypertension or blood pressure higher than normal on admission. Eight patients were cured by nasal packing and appropriate drugs, and 187 patients were treated by endoscopy and electrocoagulation. The numbers of treatment needed to stop bleeding were 1 time in 184 cases (98.4%), 2 times in 3 cases (1.6%). Thirteen cases did not have certain bleeding point, while the other 174 had certain one or more bleeding sites. The rewarded bleeding sites were 222, which were found in the following different sites: posterior inferior nasal meatus (33.3%, 74 /222), olfactory cleft of nasal septum (26.6%, 59/222), the root of the middle turbinate (14.0%, 31/222), and so on. Hypertension and diabetes were risk factors (OR value was 3.411, 7.142, both P epistaxis are mainly found in males and are almost unilatera1. Hypertension and diabetes are the common risk factor. The most effective and safe treatment for intractable deep-seated epistaxis is electrocoagulation under nasal endoscopy.

    Previous findings have been mixed in terms of identifying a distinct pattern of neuropsychological deficits in children with frontal lobe epilepsy (FLE) and in those with temporal lobe epilepsy (TLE). The current study investigated the neuropsychological similarities and differences across these two pediatric medically intractable localization-related epilepsies. Thirty-eight children with FLE, 20 children with TLE, and 40 healthy children (HC) participated in this study. A comprehensive battery of standardized tests assessed five neuropsychological domains including intelligence, language, memory, executive function, and motor function. A principal component analysis (PCA) was used to distill our neuropsychological measures into latent components to compare between groups. Principal component analysis extracted 5 latent components: executive function (F1), verbal semantics (F2), motor (F3), nonverbal cognition/impulsivity (F4), and verbal cognition/attention (F5). The group with FLE differed from the HC group on F1, F2, F4, and F5, and had worse performance than the group with TLE on F1; the group with TLE had lower performance relative to the HC group on F2. Our findings suggest that, in comparison with neurotypically developing children, children with medically intractable FLE have more widespread neuropsychological impairments than do children with TLE. The differences between the two patient groups were greatest for the factor score most clearly related to executive function. The results provide mixed support for the concept of specificity in neuropsychological dysfunction among different subtypes of localization-related medically intractable childhood epilepsies.

    To describe the experience of five Israeli pediatric epilepsy clinics treating children and adolescents diagnosed as having intractable epilepsy with a regimen of medical cannabis oil. A retrospective study describing the effect of cannabidiol (CBD)-enriched medical cannabis on children with epilepsy. The cohort included 74 patients (age range 1-18 years) with intractable epilepsy resistant to >7 antiepileptic drugs. Forty-nine (66%) also failed a ketogenic diet, vagal nerve stimulator implantation, or both. They all started medical cannabis oil treatment between 2-11/2014 and were treated for at least 3 months (average 6 months). The selected formula contained CBD and tetrahydrocannabinol at a ratio of 20:1 dissolved in olive oil. The CBD dose ranged from 1 to 20mg/kg/d. Seizure frequency was assessed by parental report during clinical visits. CBD treatment yielded a significant positive effect on seizure load. Most of the children (66/74, 89%) reported reduction in seizure frequency: 13 (18%) reported 75-100% reduction, 25 (34%) reported 50-75% reduction, 9 (12%) reported 25-50% reduction, and 19 (26%) reported CBD withdrawal. In addition, we observed improvement in behavior and alertness, language, communication, motor skills and sleep. Adverse reactions included somnolence, fatigue, gastrointestinal disturbances and irritability leading to withdrawal of cannabis use in 5 patients. The results of this multicenter study on CBD treatment for intractable epilepsy in a population of children and adolescents are highly promising. Further prospective, well-designed clinical trials using enriched CBD medical cannabis are warranted. Copyright © 2016 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

    Neuropathic pain remains intractable and the development of new therapeutic strategies are urgently required. Accumulating evidence indicates that overproduction of oxidative stress is a key event in the pathogenesis of neuropathic pain. However, repeated intra-peritoneal or intrathecal injections of antioxidants are unsuitable for continuous use in therapy. Here we show a novel therapeutic method against neuropathic pain: drinking water containing molecular hydrogen (H2) as antioxidant. The effect of hydrogen on neuropathic pain was investigated using a partial sciatic nerve ligation model in mice. As indicators of neuropathic pain, temporal aspects of mechanical allodynia and thermal hyperalgesia were analysed for 3 weeks after ligation. Mechanical allodynia and thermal hyperalgesia were measured using the von Frey test and the plantar test, respectively. When mice were allowed to drink water containing hydrogen at a saturated level ad libitum after ligation, both allodynia and hyperalgesia were alleviated. These symptoms were also alleviated when hydrogen was administered only for the induction phase (from day 0 to 4 after ligation). When hydrogen was administered only for the maintenance phase (from day 4 to 21 after ligation), hyperalgesia but not allodynia was alleviated. Immunohistochemical staining for the oxidative stress marker, 4-hydroxy-2-nonenal and 8-hydroxydeoxyguanosine, showed that hydrogen administration suppressed oxidative stress induced by ligation in the spinal cord and the dorsal root ganglion. In conclusion, oral administration of hydrogen water may be useful for alleviating neuropathic pain in a clinical setting. PMID:24941001

    Maximum likelihood parameter estimation and sampling from Bayesian posterior distributions are problematic when the probability density for the parameter of interest involves an intractable normalising constant which is also a function of that parameter. In this paper, an auxiliary variable method...... is presented which requires only that independent samples can be drawn from the unnormalised density at any particular parameter value. The proposal distribution is constructed so that the normalising constant cancels from the Metropolis–Hastings ratio. The method is illustrated by producing posterior samples...

    Although hemolytic anemia after mitral valve replacement (MVR) is well recognized, hemolytic anemia associated with mitral valve repair is an uncommon condition. Furthermore, persistent and severe hemolytic anemia despite of medical treatment subsequently requiring reoperation is extremely rare. We here report three cases of intractable hemolytic anemia after mitral valve repair leading to MVR. Collision of regurgitant jet into the annuloplasty ring was the speculated mechanism of hemolysis in all cases. After MVR, all of them experienced immediate resolution of the hemolytic anemia. © 2013, Wiley Periodicals, Inc.

    We report a case of an intractable fistula repaired by transsacral direct suture. A 65-year-old man underwent low anterior resection for rectal cancer. He subsequently underwent ileostomy due to anastomosis leakage. The fistula of the anastomosis persisted 3 months after surgery. He underwent surgery to repair the fistula using a transsacral approach. After removing the coccyx, the fistula in the postrectal space was exposed directly. The presence of the fistula was confirmed by an air leak test and was closed by direct suture. After 33 days, the patient underwent ileostomy closure.

    Full Text Available Von-Willebrand disease (VWD is one of the platelet dysfunction disorders that results from a deficiency of Von-Willebrand factor, which is essential for hemostasis. VWD patients typically have normal laboratory results on screening for bleeding disorders. To suspect and diagnose VWD, a careful review of past medical history and laboratory tests is critical. A 59-year-old male patient presented with intractable nasal bleeding after nasal polypectomy. The bleeding was controlled by platelet transfusion, and he was later diagnosed with VWD.

    Extrarenal Wilms tumor (ERWT) is a well-established entity which most commonly arises within the genitourinary tract, including intracoelomic paranephric soft tissue. Rarely, ERWT arises within teratoma, and it tends to occur predominantly in distinct settings, such as females with spinal defects and males with testicular teratomas. We report a unique ERWT arising within an extracoelomic teratoma of the paraspinal musculature, thereby expanding the range of reported locations for this unusual tumor.

  3. Decreased pain perception by unconscious emotional pictures

    Full Text Available Pain perception arises from a complex interaction between a nociceptive stimulus and different emotional and cognitive factors, which appear to be mediated by both automatic and controlled systems. Previous evidence has shown that whereas conscious processing of unpleasant stimuli enhances pain perception, emotional influences on pain under unaware conditions are much less known. The aim of the present study was to investigate the modulation of pain perception by unconscious emotional pictures through an emotional masking paradigm. Two kinds of both somatosensory (painful and non-painful and emotional stimulation (negative and neutral pictures were employed. Fifty pain-free participants were asked to rate the perception of pain they were feeling in response to laser-induced somatosensory stimuli as faster as they can. Data from pain intensity and reaction times were measured. Statistical analyses revealed a significant effect for the interaction between pain and emotional stimulation, but surprisingly this relationship was opposite to expected. In particular, lower pain intensity scores and longer reaction times were found in response to negative images being strengthened this effect for painful stimulation. Present findings suggest a clear pain perception modulation by unconscious emotional contexts. Attentional capture mechanisms triggered by unaware negative stimulation could explain this phenomenon leading to a withdrawal of processing resources from pain.

    The Wada test was performed for lateralization of language and memory function, using intracarotid injection of Sodium Amytal. But the internal carotid artery (ICA) Wada test has some limitations for testing memory function. The posterior cerebral artery (PCA) Wada test has been designed to modify the ICA Wada test for testing memory function selectively. In our study, 10 patients out of 12 patients with intractable seizure underwent only the ICA Wada test and the other 2 patients underwent both the ICA and the selective PCA Wada test. In all 12 patients undergoing the ICA Wada test, we successfully localized speech and language dominance. Four of 12 patients who underwent the ICA Wada test for evaluation of memory function displayed superior memory functions in one hemisphere, but the other hemisphere also significantly contributed to memory. The selective PCA Wada test, performed in 2 patients, showed successful results of memory function test in both patients. Four of 12 patients underwent temporal lobectomy and there was no major post-operative language or memory deficits. We concluded that the ICA and PCA Wada tests are useful for preoperative evaluation of medically intractable epilepsy, and the PCA Wada test is valuable in memory evaluation in some patients who have high risk of postoperative global amnesia after temporal lobectomy following equivocal results of memory function by the ICA Wada test

  5. A Monte Carlo Metropolis-Hastings Algorithm for Sampling from Distributions with Intractable Normalizing Constants

    Simulating from distributions with intractable normalizing constants has been a long-standing problem inmachine learning. In this letter, we propose a new algorithm, the Monte Carlo Metropolis-Hastings (MCMH) algorithm, for tackling this problem. The MCMH algorithm is a Monte Carlo version of the Metropolis-Hastings algorithm. It replaces the unknown normalizing constant ratio by a Monte Carlo estimate in simulations, while still converges, as shown in the letter, to the desired target distribution under mild conditions. The MCMH algorithm is illustrated with spatial autologistic models and exponential random graph models. Unlike other auxiliary variable Markov chain Monte Carlo (MCMC) algorithms, such as the Møller and exchange algorithms, the MCMH algorithm avoids the requirement for perfect sampling, and thus can be applied to many statistical models for which perfect sampling is not available or very expensive. TheMCMHalgorithm can also be applied to Bayesian inference for random effect models and missing data problems that involve simulations from a distribution with intractable integrals. © 2013 Massachusetts Institute of Technology.

    Since the 1920s, a ketogenic diet, of low-carbohydrate, adequate-protein and high-fat content, has been used for the treatment of intractable childhood epilepsy. A decade ago this diet was tried as a last resort in the treatment of intractable epilepsy. However, recent advances in ketogenic diet have enabled it to become more commonly used worldwide even early in the course of epilepsy. Two less-restrictive ketogenic diets, namely, the modified Atkins diet and low-glycemic-index treatment, have been developed. These diets allow the patients and their families to choose a more liberal menu. Furthermore, a randomized controlled trial found that the ketogenic diet has a significant benefit, which strengthens the supportive evidence. Recently, an international consensus statement guiding optimal clinical management has been published, allowing clinicians to provide standardized treatment. There has also been increased interest in investigating the mechanisms of action of ketogenic diet using various experimental models. The authors review the history, efficacy, side effects, and possible mechanisms underlying the ketogenic diet, as well as the experience with the ketogenic diet at Tokyo Women's Medical University.

  8. Could Cannabidiol be a Treatment Option for Intractable Childhood and Adolescent Epilepsy?

    Epilepsy is an important disease that affects brain function, particularly in those under 3 years old. Uncontrolled seizures can affect cognitive function and quality of life. For these reasons, many trials have been conducted to investigate treatments for pediatric epilepsy. Currently, many antiepileptic drugs are available for the treatment of epilepsy, but cases of intractable epilepsy continue to exist. In the past, cannabis has been tested as a potential treatment of intractable epilepsy. Since 2013, 10 epilepsy centers in America have conducted research regarding the efficacy of cannabis to treat epilepsy. Cannabis has many components, including cannabidiol (CBD) and Δ 9 -tetrahydrocannabinol (THC). THC has psychoactive properties exerted through its binding of the cannabinoid receptor (CBR) whereas CBD is a CBR antagonist. The inhibition of epilepsy by CBD may therefore be caused by various mechanisms, although the detailed mechanisms of CBD actions have not yet been well defined. In most studies, trial doses of CBD were 2-5 mg/kg/day. Several such studies have shown that CBD does have efficacy for treatment of epilepsy. Reported adverse effects of CBD were mostly mild, including drowsiness, diarrhea, and decreased appetite. Severe adverse reactions requiring treatment, such as status epilepticus, have also been reported but it is not clear that this is related to CBD. Furthermore, many previous studies have been limited by an open-label or survey design. In future, double-blind, controlled trials are required and the use of CBD to treat other neurological problems should also be investigated.

    Birt-Hogg-Dubé syndrome (BHD) is an inherited disorder associated with a germline mutation of the folliculin (FLCN) gene. Most patients with BHD have multiple pulmonary cysts, and are at high risk of repeated pneumothorax. Although an increasing number of patients are diagnosed with BHD by genetic testing, therapeutic approaches for intractable pneumothorax have not yet been described. We treated three patients who had repeated episodes of pneumothorax. All had multiple pulmonary cysts in the lower lobes, and two had a family history of pneumothorax. Video-assisted thoracic surgery was used to perform wedge resections and partial pleural covering of the cystic lesions. The partial pleural covering technique used sheets of polyglycolic acid felt or regenerative oxidized cellulose mesh. The resected tissues underwent histopathological evaluation, and peripheral blood leukocytes were tested for FLCN mutations. The operative times were less than 2 h, and there were no complications. The resected cysts had histopathological features characteristic of BHD lung. All patients were found to have FLCN germline mutations; thus their repeated pneumothoraces were a manifestation of BHD. None of the patients developed respiratory problems after undergoing the partial pleural covering procedure, and they have all been well without pneumothorax for 30 months or more. Partial pleural covering combined with resection of protruding cysts should be a safe and effective therapeutic approach for BHD patients with intractable pneumothorax. Further investigation is needed to establish a detailed protocol for treatment of pneumothorax that results in minimal functional impairment. © 2015 John Wiley & Sons Ltd.

    A key challenge in evolving control systems for robots using neural networks is training tractability. Evolving monolithic fixed topology neural networks is shown to be intractable with limited supervision in high dimensional search spaces. Common strategies to overcome this limitation are to provide more supervision by encouraging particular solution strategies, manually decomposing the task and segmenting the search space and network. These strategies require a supervisor with domain knowledge and may not be feasible for difficult tasks where novel concepts are required. The alternate strategy is to use self-organized task decomposition to solve difficult tasks with limited supervision. The artificial neural tissue (ANT) approach presented here uses self-organized task decomposition to solve tasks. ANT inspired by neurobiology combines standard neural networks with a novel wireless signaling scheme modeling chemical diffusion of neurotransmitters. These chemicals are used to dynamically activate and inhibit wired network of neurons using a coarse-coding framework. Using only a global fitness function that does not encourage a predefined solution, modular networks of neurons are shown to self-organize and perform task decomposition. This approach solves the sign-following task found to be intractable with conventional fixed and variable topology networks. In this paper, key attributes of the ANT architecture that perform self-organized task decomposition are shown. The architecture is robust and scalable to number of neurons, synaptic connections, and initialization parameters.

    The objective of this study was to assess the effect on health-related quality of life of acupuncture and sham acupuncture as adjunctive treatment in intractable epilepsy. We performed a randomized controlled trail with two parallel treatment arms at The National Center for Epilepsy in Norway, a comprehensive epilepsy center. Thirty-four patients with long-standing drug resistant epilepsy completed the study. The intervention consisted of 20 acupuncture treatments (bilateral needling of three acupoints plus one or two individually chosen points) or sham acupuncture (bilateral needling with smaller needles of three points outside the traditional meridians) over 8 weeks. The main outcome measures were changes in mean health-related quality of life scores for the two groups after 8 weeks, using the 89-item Quality of Life in Epilepsy (QOLIE-89) questionnaire. We found no difference between the acupuncture and sham acupuncture groups in score changes in any dimension of the QOLIE-89 questionnaire, despite testing a large number of dimensions. We also found no change in QOLIE-89 scores between baseline and 8 weeks in either groups. In conclusion, we could not demonstrate a significant effect of traditional acupuncture or sham acupuncture on the health-related quality of life of patients with intractable epilepsy.

    Typhoid fever is an enteric infection caused by Salmonella typhi. In Indonesia, typhoid fever is endemic with high incidence of the disease. In daily practice we frequently have patients with bronchial asthma, and it is becoming worse when these patients get typhoid fever. After oral ingestion, Salmonella typhi invades the the intestine mucosa after conducted by microbial binding to epithelial cells, destroying the microfold cells (M cell) then passed through the lamina propria and detected by dendritic cells (DC) which express a variety of pathogen recognition receptors on the surfaces, including Toll-Like Receptor (TLR). expressed on macrophages and on intestinal epithelial cells inducing degradation of IB, and translocation of NF-B (Nuclear Factor-Kappa Beta). This process initiates the induction of pro-inflammatory gene expression profile adhesion molecules, chemokines, adhesion molecules, and other proteins that induce and perpetuate the inflammation in host cells then will induce acute ant intractable attack of bronchial asthma. The role of typhoid fever in bronchial asthma, especially in persons with acute attack of bronchial asthma, is not well understood. In this article, we will discuss the role of typhoid fever in the bronchial asthma patients which may cause bronchial asthma significantly become more severe even triggering the acute and intractable attack of bronchial asthma. This fact makes an important point, to treat completely the typhoid fever in patients with bronchial asthma.

    Background Mutations in the KIAA2022 gene have been reported in male patients with X-linked intellectual disability, and related female carriers were unaffected. Here, we report 14 female patients who carry a heterozygous de novo KIAA2022 mutation and share a phenotype characterised by intellectual disability and epilepsy. Methods Reported females were selected for genetic testing because of substantial developmental problems and/or epilepsy. X-inactivation and expression studies were performed when possible. Results All mutations were predicted to result in a frameshift or premature stop. 12 out of 14 patients had intractable epilepsy with myoclonic and/or absence seizures, and generalised in 11. Thirteen patients had mild to severe intellectual disability. This female phenotype partially overlaps with the reported male phenotype which consists of more severe intellectual disability, microcephaly, growth retardation, facial dysmorphisms and, less frequently, epilepsy. One female patient showed completely skewed X-inactivation, complete absence of RNA expression in blood and a phenotype similar to male patients. In the six other tested patients, X-inactivation was random, confirmed by a non-significant twofold to threefold decrease of RNA expression in blood, consistent with the expected mosaicism between cells expressing mutant or normal KIAA2022 alleles. Conclusions Heterozygous loss of KIAA2022 expression is a cause of intellectual disability in females. Compared with its hemizygous male counterpart, the heterozygous female disease has less severe intellectual disability, but is more often associated with a severe and intractable myoclonic epilepsy.

    Full Text Available Antigravitational deviation of the cupula of the lateral semicircular canal, which is also called light cupula, evokes persistent direction-changing geotropic nystagmus with a neutral point. No intractable cases of this condition have been reported. In our case, a 67-year-old man complained of positional vertigo 3 months after developing idiopathic sudden hearing loss in the right ear with vertigo. He showed a persistent direction-changing geotropic nystagmus with a leftward beating nystagmus in the supine position. The nystagmus resolved when his head was turned approximately 30° to the right. He was diagnosed with light cupula of the right lateral semicircular canal and was subsequently treated with an antivertiginous agent. However, his symptoms and positional nystagmus did not improve, so the right lateral semicircular canal was plugged by surgery. One month after surgery, his positional vertigo and nystagmus were completely resolved. We speculated that the cause of the patient’s intractable light cupula was an enlarged cupula caused by his idiopathic sudden hearing loss.

    Full Text Available Most patients with herpes simplex virus Type I encephalitis experience an acute, monophasic illness. Chronic encephalitis is much less common, and few late relapses are associated with intractable seizure disorders. A 10-year-old boy was admitted to our institution for intractable epilepsy as part of an evaluation for epilepsy surgery. His history was significant for herpes meningitis at age 4 months. At that time, he presented to an outside hospital with fever for three days, with acyclovir treatment beginning on day 4 of his 40-day hospital course. He later developed infantile spasms and ultimately a mixed seizure disorder. Video electroencephalogram showed a Lennox-Gastaut-type pattern with frequent right frontotemporal spikes. Imaging studies showed an abnormality in the right frontal operculum. Based on these findings, he underwent a right frontal lobectomy. Neuropathology demonstrated chronic granulomatous inflammation with focal necrosis and mineralizations. Scattered lymphocytes, microglial nodules and nonnecrotizing granulomas were present with multinucleated giant cells. Immunohistochemistry for herpes simplex virus showed focal immunoreactivity. After undergoing acyclovir therapy, he returned to baseline with decreased seizure frequency. This rare form of herpes encephalitis has only been reported in children, but the initial presentation of meningitis and the approximate 10-year-time interval in this case are unusual.

    Chloramphenicol (CP) is recently one of the rarely-used antibiotics. In this study, we present four patients with intractable bacterial meningitis, who were successfully treated with CP and discuss the therapeutic indications of CP in these pediatric cases. The patients were diagnosed as bacterial meningitis at the ages ranging from 2 months to 1 year and 4 months. The causative organisms found in three of the patients were H. influenzae and in the fourth patient, S. pneumoniae. According to the microbial sensitivity tests, these organisms were highly sensitive to antibiotics including ceftriaxone, meropenem and/or panipenem/betamipron. Treatment with these antibiotics was initially effective; however, recurrences of meningitis appeared in all patients. Administration of CP (100 mg/kg/day) started between the 11th and the 58th days, and was continued for 9 days up to 19 days. Their fever had disappeared within four days after the administration of CP, and it was confirmed that all patients completely recovered from meningitis. Two of the patients developed a mild degree of anemia, but soon recovered after the discontinuation of CP. None of them had neurological sequela. We recommend CP as one of the choices for the treatment of intractable bacterial meningitis.

    2015-08-01

    Postdural punctural headache (PDPH) following spinal anesthesia is due to intracranial hypotension caused by cerebrospinal fluid (CSF) leakage, and it is occasionally accompanied by an intracranial hematoma. To the best of our knowledge, an intracranial chronic subdural hematoma (CSDH) presenting with an intractable headache after a cervical epidural steroid injection (ESI) has not been reported. A 39-year-old woman without any history of trauma underwent a cervical ESI for a herniated nucleus pulposus at the C5-6 level. One month later, she presented with a severe headache that was not relieved by analgesic medication, which changed in character from being positional to non-positional during the preceding month. Brain magnetic resonance imaging revealed a CSDH along the left convexity. Emergency burr-hole drainage was performed and the headache abated. This report indicates that an intracranial CSDH should be considered a possible complication after ESI. In addition, the event of an intractable and changing PDPH after ESI suggests further evaluation for diagnosis of an intracranial hematoma.

    Full Text Available Abstract Background The mechanisms subserving deep spinal pain have not been studied as well as those related to the skin and to deep pain in peripheral limb structures. The clinical phenomenology of deep spinal pain presents unique features which call for investigations which can explain these at a mechanistic level. Methods Targeted searches of the literature were conducted and the relevant materials reviewed for applicability to the thesis that deep spinal pain is distinctive from deep pain in the peripheral limb structures. Topics related to the neuroanatomy and neurophysiology of deep spinal pain were organized in a hierarchical format for content review. Results Since the 1980’s the innervation characteristics of the spinal joints and deep muscles have been elucidated. Afferent connections subserving pain have been identified in a distinctive somatotopic organization within the spinal cord whereby afferents from deep spinal tissues terminate primarily in the lateral dorsal horn while those from deep peripheral tissues terminate primarily in the medial dorsal horn. Mechanisms underlying the clinical phenomena of referred pain from the spine, poor localization of spinal pain and chronicity of spine pain have emerged from the literature and are reviewed here, especially emphasizing the somatotopic organization and hyperconvergence of dorsal horn “low back (spinal neurons”. Taken together, these findings provide preliminary support for the hypothesis that deep spine pain is different from deep pain arising from peripheral limb structures. Conclusions This thesis addressed the question “what is different about spine pain?” Neuroanatomic and neurophysiologic findings from studies in the last twenty years provide preliminary support for the thesis that deep spine pain is different from deep pain arising from peripheral limb structures.

    Highlights: • Purpose of this review is to address the current concepts on the pathophysiology of discogenic, radicular, facet and dysfunctional spinal pain, focusing on the role of the imaging in the diagnostic setting, to potentially address a correct approach also to minimally invasive interventional techniques. • Special attention will be given to the discogenic pain, actually considered as the most frequent cause of chronic low back pain. • The correct distinction between referred pain and radicular pain contributes to give a more correct approach to spinal pain. • The pathogenesis of chronic pain renders this pain a true pathology requiring a specific management. - Abstract: The spinal pain, and expecially the low back pain (LBP), represents the second cause for a medical consultation in primary care setting and a leading cause of disability worldwide [1]. LBP is more often idiopathic. It has as most frequent cause the internal disc disruption (IDD) and is referred to as discogenic pain. IDD refers to annular fissures, disc collapse and mechanical failure, with no significant modification of external disc shape, with or without endplates changes. IDD is described as a separate clinical entity in respect to disc herniation, segmental instability and degenerative disc desease (DDD).

    Highlights: • Purpose of this review is to address the current concepts on the pathophysiology of discogenic, radicular, facet and dysfunctional spinal pain, focusing on the role of the imaging in the diagnostic setting, to potentially address a correct approach also to minimally invasive interventional techniques. • Special attention will be given to the discogenic pain, actually considered as the most frequent cause of chronic low back pain. • The correct distinction between referred pain and radicular pain contributes to give a more correct approach to spinal pain. • The pathogenesis of chronic pain renders this pain a true pathology requiring a specific management. - Abstract: The spinal pain, and expecially the low back pain (LBP), represents the second cause for a medical consultation in primary care setting and a leading cause of disability worldwide [1]. LBP is more often idiopathic. It has as most frequent cause the internal disc disruption (IDD) and is referred to as discogenic pain. IDD refers to annular fissures, disc collapse and mechanical failure, with no significant modification of external disc shape, with or without endplates changes. IDD is described as a separate clinical entity in respect to disc herniation, segmental instability and degenerative disc desease (DDD). The radicular pain has as most frequent causes a disc herniation and a canal stenosis. Both discogenic and radicular pain also have either a mechanical and an inflammatory genesis. For to be richly innervated, facet joints can be a direct source of pain, while for their degenerative changes cause compression of nerve roots in lateral recesses and in the neural foramina. Degenerative instability is a common and often misdiagnosed cause of axial and radicular pain, being also a frequent indication for surgery. Acute pain tends to extinguish along with its cause, but the setting of complex processes of peripheral and central sensitization may influence its evolution in chronic

    Biceps tendinopathy is a relatively common ailment that typically presents as pain, tenderness, and weakness in the tendon of the long head of the biceps brachii. Though it is often associated with degenerative processes of the rotator cuff and the joint, this is not always the case, thus, the etiology remains considerably unknown. There has been recent interest in elucidating the pathogenesis of tendinopathy, since it can be an agent of chronic pain, and is difficult to manage. The purpose of this article is to critically evaluate relevant published research that reflects the current understanding of pain and how it relates to biceps tendinopathy. A review of the literature was conducted to create an organized picture of how pain arises and manifests itself, and how the mechanism behind biceps tendinopathy possibly results in pain. Chronic pain is thought to arise from neurogenic inflammation, central pain sensitization, excitatory nerve augmentation, inhibitory nerve loss, and/or dysregulation of supraspinal structures; thus, the connections of these theories to the ones regarding the generation of biceps tendinopathy, particularly the neural theory, are discussed. Pain mediators such as tachykinins, CGRP, and alarmins, in addition to nervous system ion channels, are highlighted as possible avenues for research in tendinopathy pain. Recognition of the nociceptive mechanisms and molecular of biceps tendinopathy might aid in the development of novel treatment strategies for managing anterior shoulder pain due to a symptomatic biceps tendon.

    To evaluate the efficacy and safety of long-term ketogenic diet (KD) on the children with intractable epilepsy. This was a prospective, open-label study of intractable epilepsy patients treated with the classic KD with a lipid-to-nonlipid ratio 4:1 between October 2004 and July 2011 at five Chinese epilepsy centers. A total of 299 patients were enrolled. The patients were divided into different groups according to age (including the below-1-year-old group, 1-to-3-year-old group, 3-to-6-year-old group, 6-to-10-year-old group, and over-10-year-old group), etiology (cryptogenic epilepsy, symptomatic epilepsy, and idiopathic epilepsy), and the seizure types (included infantile spasm, Lennox-Gastaut syndrome, Ohtahara syndrome, tuberous sclerosis, Dravet syndrome, generalized epilepsy, and partial epilepsy). Parents were assigned to write seizure diaries which recorded the seizure presentations, tolerability, and complications associated with the KD. Patients' weight and height were measured every week. Blood β-hydroxybutyric acid, blood sugar, and urinary ketone bodies were monitored closely. Patients were followed up through telephone calls by the nutritionists every month and regular outpatient visits or hospitalizations were recommended at all time-points which included the third, sixth and twelfth month after initiation. Efficacy was measured through seizure frequency. The variables related to the efficacy were also analyzed. SPSS 17.0 was used for all statistical analysis. At 3, 6, and 12 months after initiation, 65.9%, 44.8%, and 26.4% patients remained on the diet, and 37.4%, 26.1%, and 20.4% had a > 50% reduction in their seizure frequency, including 21.7%, 10.7%, and 11.0% who became seizure free, respectively. At 24 months after initiation, 29 patients remained on the diet, and 28 patients had a > 90% seizure reduction, including five became seizure free. At 36 months after initiation, 7 patients remained on the diet, and all of them had a > 90% seizure

    In 1972, the Ministry of Health, Labour and Welfare of Japan defined intractable diseases as those with unknown etiology, no established treatment regimens, and severe sequelae of physical, mental and social difficulties. Since then, the Ministry has promoted scientific research on these diseases and offered financial support to those suffering from their effects. The purpose of the present study was to analyze trends in deaths from the diseases in Japan over the period from 1972-2004. For the selected intractable diseases with 100 deaths or more per year, crude (CDR) and direct age-standardized death rates (ADR) were computed using the national underlying-cause-of-death mortality database of Japan based on International Classification of Diseases. Joinpoint regression analysis was applied to identify significant changes in the trends. The CDRs in the latest observed year per 1 million persons/year) for males and females were 25.55 and 25.93, respectively, for Parkinson's disease, 5.41 and 6.92 for aplastic anemia, 0.87 and 3.50 for systemic lupus erythematosus, 2.93 and 2.36 for amyloidosis, 1.40 and 1.54 for polyarteritis nodosa, 1.34 and 1.61 for idiopathic thrombocytopenic purpura, and 1.02 and 0.74 for ulcerative colitis. The respective annual percentage changes (APCs) for males and females during the overall period decreased for ulcerative colitis (-5.2% and -7.5%), aplastic anemia (-3.6% and -3.7%), idiopathic thrombocytopenic purpura (-2.1% and -3.0%), and systemic lupus erythematosus (-0.9% and -2.6%), while the APCs increased for amyloidosis (+3.3% and +3.5%), polyarteritis nodosa (+3.2% and +4.0%), and Parkinson's disease (+0.7% in males alone). With the APCs in the latest trend phase, polyarteritis nodosa and Parkinson's disease in females showed appreciable declines; on the other hand, amyloidosis in males demonstrated the significant increase, and ulcerative colitis in males exhibited an apparent leveling off of the decline. The ADRs for most of the

    Vision is important for avoiding encounters with objects in the environment that may imperil physical integrity. We tested whether, in the absence of vision, a lower pain threshold would arise from an adaptive shift to other sensory channels. We therefore measured heat and cold pain thresholds...... that blind subjects are more attentive to signals of external threats. These findings indicate that the absence of vision from birth induces a hypersensitivity to painful stimuli, lending new support to a model of sensory integration of vision and pain processing....

    Chronic post-thoracotomy pain syndrome (PTPS) can cause significant patient distress and is frequently difficult to manage. Percutaneous intercostal nerve (ICN) cryoablation by palpation of surface landmarks can be risky, as inaccurate probe placement can lead to hemo- or pneumothorax. Experience with image-guided ICN cryoablation with treatment planning and device navigation is limited. A patient with intractable PTPS was treated with ICN cryoablation under cone-beam computed tomography guidance with software-assisted needle trajectory planning and ablation zone simulation. This procedure provided the patient ~8 weeks of relief. This case demonstrated that ICN cryoablation is feasible under image guidance with device navigation and ablation simulation and may result in a few months of pain relief in cases of intractable PTPS.

    Balás, I; Llumiguano, C; Horvath, Z; Kovér, F; Dóczi, T P

    Medial thalamotomy is one of the first stereotactic operations to have been used for neurogenic pain, has a low complication rate and no risk of the development of iatrogenic neurogenic pain. It represents selective local relief for all types of pain, without causing somatosensorial deficit. We did 39 posteromedial thalamotomies in patients with persistent intractable pain due to various disorders. The pain was assessed pre- and postoperatively on the VAS (Visual Analogic Scale). Half of the patients operated on had relief of pain after thalamotomy. In 84% (n = 39) of our cases this relief occurred on the second day, in 70% (n = 35) after three months, in 63% (n = 27) after six months, in 64% (n = 25) after nine months, in 62% (n = 23) of the patients after 12 months, and in 62% (n = 22) after 24 months. Three patients had temporary complications and one a permanent complication, but this did not make him an invalid. Posteromedial stereotactic thalamotomy under MR guidance can provide safe, effective treatment for persistent, intractable pain.

    Epilepsy is the most common chronic neurological illness in childhood and adolescence. The aim of this study was to investigate paraoxonase and arylesterase activities along with oxidative status parameters in children with intractable epilepsy. The study comprised 42 subjects with intractable epilepsy and a control group of 35 healthy subjects. Serum paraoxonase and arylesterase activities, and lipid hydroperoxide levels were determined. All paraoxonase and arylesterase activities were significantly lower in the intractable epilepsy subjects than in the controls (Pparaoxonase and arylesterase activities were decreased and the lipid hydroperoxide level was increased in patients with intractable epilepsy. These results showed that intractable epilepsy subjects may be more prone to the development of atherosclerosis. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Pain, which afflicts up to 20% of the population at any time, provides both a massive therapeutic challenge and a route to understanding mechanisms in the nervous system. Specialised sensory neurons (nociceptors signal the existence of tissue damage to the central nervous system (CNS, where pain is represented in a complex matrix involving many CNS structures. Genetic approaches to investigating pain pathways using model organisms have identified the molecular nature of the transducers, regulatory mechanisms involved in changing neuronal activity, as well as the critical role of immune system cells in driving pain pathways. In man, mapping of human pain mutants as well as twin studies and association studies of altered pain behaviour have identified important regulators of the pain system. In turn, new drug targets for chronic pain treatment have been validated in transgenic mouse studies. Thus, genetic studies of pain pathways have complemented the traditional neuroscience approaches of electrophysiology and pharmacology to give us fresh insights into the molecular basis of pain perception.

    The use of intrathecal morphine therapy has been increasing. Intrathecal morphine therapy is deemed the last resort for patients with intractable chronic non-cancer pain (CNCP) who failed other treatments including surgery and pharmaceutical interventions. However, effective treatments for patients with CNCP who "failed" this last resort because of severe side effects and lack of optimal pain control remain unclear. Here we report two successfully managed patients (Ms. S and Mr. T) who had intractable pain and significant complications years after the start of intrathecal morphine therapy. The two patients had intrathecal morphine pump implantation due to chronic consistent pain and multiple failed surgical operations in the spine. Years after morphine pump implantation, both patients had significant chronic pain and compromised function for activities of daily living. Additionally, Ms. S also had four episodes of small bowel obstruction while Mr. T was diagnosed with end stage severe "dementia". The successful management of these two patients included the simultaneous multidisciplinary approach for pain management, opioids tapering and discontinuation. The case study indicates that for patients who fail to respond to intrathecal morphine pump therapy due to side effects and lack of optimal pain control, the simultaneous multidisciplinary pain management approach and opioids tapering seem appropriate.

    The purpose of this study is to assess the clinical value of spatiotemporal source analysis for analyzing ictal magnetoencephalography (MEG). Ictal MEG and simultaneous scalp EEG was recorded in five patients with medically intractable frontal lobe epilepsy. Dynamic statistical parametric maps (dSPMs) were calculated at the peak of early ictal spikes for the purpose of estimating the spatiotemporal cortical source distribution. DSPM solutions were mapped onto a cortical surface, which was derived from each patient's MRI. Equivalent current dipoles (ECDs) were calculated using a single-dipole model for comparison with dSPMs. In all patients, dSPMs tended to have a localized activation, consistent with the clinically determined ictal onset zone, whereas most ECDs were considered to be inappropriate sources according to their goodness-of-fit values. Analyzing ictal MEG spikes by using dSPMs may provide useful information in presurgical evaluation of epilepsy.

    Gastroesophageal reflux disease (GERD) is a common complication in the spinal cord injury (SCI) population. Surgical treatment of GERD has a unique risk/benefit profile in this population. This 68-year-old male with chronic incomplete tetraplegia, dyslipidemia, and well-controlled diabetes mellitus underwent Roux-en-Y gastric bypass surgery (RYGBP) for intractable biliary reflux. Postoperatively, the patient had resolution of his symptoms but he also presented with significant weight loss and dumping syndrome. While he did have improvement in his dyslipidemia there was no change in his functional status. RYGBP is an option for refractory GERD treatment in the SCI population but preoperative risk assessment and close monitoring postoperatively is essential.

    Full Text Available Bone marrow transplantation (BMT is used to treat hematological disorders, autoimmune diseases and lymphoid cancers. Intra bone marrow-BMT (IBM-BMT has been proven to be a powerful strategy for allogeneic BMT due to the rapid hematopoietic recovery and the complete restoration of T cell functions. IBM-BMT not only replaces hematopoietic stem cells but also mesenchymal stem cells (MSMCs. MSMCs are multi-potent stem cells that can be isolated from bone marrow, umbilical cord blood, and adipose tissue. MSMCs play an important role in the support of hematopoiesis, and modify and influence the innate and adaptive immune systems. MSMCs also differentiate into mesodermal, endodermal and ectodermal lineage cells to repair tissues. This review aims to summarize the functions of bone marrow-derived- MSMCs, and the treatment of intractable diseases such as rheumatoid arthritis and malignant tumors with IBM-BMT.

    Multidrug resistance mechanisms underlying the intractability of malignant melanomas remain largely unknown. In this study, we demonstrate that the development of multidrug resistance in melanomas involves subcellular sequestration of intracellular cytotoxic drugs such as cis-diaminedichloroplatinum II (cisplatin; CDDP). CDDP is initially sequestered in subcellular organelles such as melanosomes, which significantly reduces its nuclear localization when compared with nonmelanoma/KB-3-1 epidermoid carcinoma cells. The melanosomal accumulation of CDDP remarkably modulates melanogenesis through a pronounced increase in tyrosinase activity. The altered melanogenesis manifested an 8-fold increase in both intracellular pigmentation and extracellular transport of melanosomes containing CDDP. Thus, our experiments provide evidence that melanosomes contribute to the refractory properties of melanoma cells by sequestering cytotoxic drugs and increasing melanosome-mediated drug export. Preventing melanosomal sequestration of cytotoxic drugs by inhibiting the functions of melanosomes may have great potential as an approach to improving the chemosensitivity of melanoma cells. cancer | melanosomes | skin | tumor therapy | multidrug resistance

    The aim of the present study was to evaluate serum selenium levels in children receiving olive oil-based ketogenic diet (KD) for intractable seizures for at least 1 year. Out of 320 patients who were initiated on KD, patients who continued receiving KD for at least 12 months were enrolled. Sixteen patients who had selenium deficiency at the time of starting KD were excluded. Finally, a total of 110 patients (mean age 7.3 ± 4.2 years) were included. Serum selenium levels were measured at baseline and at 3, 6, and 12 months after treatment initiation by using atomic absorption spectroscopy. Selenium deficiency was defined as a serum selenium level ketogenic diet suggests that patients on this highly prescriptive dietary treatment need close monitoring of this trace element.

    The importance of hope in promoting conciliatory attitudes has been asserted in the field of conflict resolution. However, little is known about conditions inducing hope, especially in intractable conflicts, where reference to the outgroup may backfire. In the current research, five studies yielded convergent support for the hypothesis that hope for peace stems from a general perception of the world as changing. In Study 1, coders observed associations between belief in a changing world, hope regarding peace, and support for concessions. Study 2 revealed the hypothesized relations using self-reported measures. Studies 3 and 4 established causality by instilling a perception of the world as changing (vs. unchanging) using narrative and drawing manipulations. Study 5 compared the changing world message with a control condition during conflict escalation. Across studies, although the specific context was not referred to, the belief in a changing world increased support for concessions through hope for peace. PMID:25713171

    The aim of this study was to analyze multidrug resistance-associated protein 1 (MRP1) expression of peripheral blood of children intractable epilepsy. Sixty children with epilepsy admitted to outpatient and inpatient services of Xuzhou Children's Hospital between November 2010 and October 2011 were divided into a refractory epilepsy group and a drug-controlled epilepsy group, with 30 cases each. Thirty healthy children who went to the hospital in the same year for health examination were enrolled as a control group. Reverse transcriptase polymerase chain reaction and Western blot method were used to determine peripheral blood MRP1 level, mRNA, and protein content of the 3 groups. MRP1 expression in the refractory epilepsy group was significantly higher than those of the epilepsy group with good drug control and of the control group. All differences had statistical significance (P0.05). Peripheral blood MRP1 expression in patients with refractory epilepsy increases.

    Chronic abdominal pain is a common clinical problem in primary care, and is usually referred to gastroenterologists or general surgeons. Although up to 20% of cases of idiopathic abdominal pain arise in structures of the abdominal wall, this is frequently overlooked as a possible cause. It includes pain arising from structures of the abdominal wall including skin, parietal peritoneum, cellular subcutaneous tissue, aponeuroses, abdominal muscles and somatosensorial innervation from lower dorsal roots. The diagnosis is based on anamnesis and physical examination. Carnett's sign is a simple maneuver that discriminates between parietal and visceral pain. Management with topical anesthesia is effective in a majority of patients and can help to confirm the diagnosis.

    Secondary lymphedema occurs after trauma, cancer surgery, or obesity, and wounds in lymphedema can easily become intractable. We report positive results using lymphatico-venous anastomosis (LVA) to treat a post-traumatic lymph fistula and an intractable ulcer in a severely obese patient. A 41-year-old male (BMI 51.8), one year prior, had a traffic injury, and had an 18-cm contusion in his right leg. Six months later, lymph leakage in a 14 cm × 8 cm region and a 5 cm × 3 cm skin ulcer occurred in the center of the wound. We made a diagnosis of lymphedema resulting from obesity, accompanied with lymphorrhea and intractable ulcer. He was unable to reach his legs owing to obesity, making complex physical therapy impossible. We performed LVA under local anesthesia. The lymphorrhea healed 2 weeks after the operation and had not recurred 3 months after the operation. The leg lymphedema improved after the surgery without the compression therapy. In cases of intractable ulcers, suspected of being caused by lymphostasis, treatments indicated for lymphedema, for example LVA, may possibly allow satisfactory wound healing. © 2013 Wiley Periodicals, Inc.

    The exact origin and process of development of cerebral cavernous malformations (CCMs) is currently unknown. In this article, the authors present de novo CCM formation in a patient with intractable epilepsy and discuss the pathogenesis of CCM in light of several current theories. A 34-year-old man presented with a 10-year history of intractable seizures. His neurological examination was normal, and the initial magnetic resonance imaging (MRI) was suggestive of right mesial temporal sclerosis (MTS). Follow-up MRI study showed development of CCM in the right frontal region. Subsequently, invasive monitoring revealed right temporal seizure source, prompting right temporal lobectomy that resulted in abolition of epilepsy. Histological diagnosis of CCM was confirmed after the lesion was removed in a separate surgery. The patient recovered to normal lifestyle without any complications. This appears to be a first documented case of de novo CCM formation in the setting of intractable epilepsy with ipsilateral MTS. Since the possibility of lesion development cannot be ruled out based on clinical examination, updated imaging and thorough neurophysiological workup are needed for successful treatment of patients with intractable epilepsy.

    Mutations in the KIAA2022 gene have been reported in male patients with X-linked intellectual disability, and related female carriers were unaffected. Here, we report 14 female patients who carry a heterozygous de novo KIAA2022 mutation and share a phenotype characterised by intellectual disability and epilepsy. Reported females were selected for genetic testing because of substantial developmental problems and/or epilepsy. X-inactivation and expression studies were performed when possible. All mutations were predicted to result in a frameshift or premature stop. 12 out of 14 patients had intractable epilepsy with myoclonic and/or absence seizures, and generalised in 11. Thirteen patients had mild to severe intellectual disability. This female phenotype partially overlaps with the reported male phenotype which consists of more severe intellectual disability, microcephaly, growth retardation, facial dysmorphisms and, less frequently, epilepsy. One female patient showed completely skewed X-inactivation, complete absence of RNA expression in blood and a phenotype similar to male patients. In the six other tested patients, X-inactivation was random, confirmed by a non-significant twofold to threefold decrease of RNA expression in blood, consistent with the expected mosaicism between cells expressing mutant or normal KIAA2022 alleles. Heterozygous loss of KIAA2022 expression is a cause of intellectual disability in females. Compared with its hemizygous male counterpart, the heterozygous female disease has less severe intellectual disability, but is more often associated with a severe and intractable myoclonic epilepsy.

    Intractable conflicts are omnipresent in environmental management. These conflicts do not necessarily resist resolution but need to be fundamentally transformed in order to reach agreement. Reframing, a process that allows disputants to create new alternative understandings of the problem, is one way of transforming these conflicts. Cognitive and interactional reframing are the two major approaches to conflict transformation. These approaches have some drawbacks. Cognitive reframing does not guarantee commensurate consideration of all disputants' views about the problem. Interactional reframing is prone to inter-disputant influences that interfere with presenting the problems as accurately as they exist in disputants' minds. Inadequate consideration of other disputants' views and inter-disputant influences often lead to inaccurate problem identification and definition. This in turn leads to solving the wrong problem, enabling intractability to persist. Proper problem identification and definition requires commensurate consideration of all sides of the conflict while minimizing inter-disputant influences. From a problem diagnosis perspective, we show how Q methodology is used to reframe environmental problems, rendering them more tractable to analysis while minimizing the influence of who disputants are talking with, and without ignoring the perspectives of other disputants. Using a case of contentious All-Terrain Vehicle (ATV) use in a state-administered public land, conflicting parties reframed the problem by prioritizing issues, outlining areas and levels of consensus and disagreement, and revealing inherent unrecognized and/or unspoken agendas. The reframing process surprisingly revealed several areas of common ground in disputants' diagnosis of the problem, including lack of emphasis on environmental protection and uncoordinated management factions. Emergent frames were misaligned on some issues, such as the behaviors of ATV riders and the role of management

    Treatment of blepharoptosis caused by ocular myasthenia gravis (OMG) is challenging in patients with serious side effects or failed response to medical therapy. Only a few surgical reports have been published for refractory myathenic blepharoptosis. This study is aimed at the evaluation of the surgical outcome of blepharoptosis correction in intractable OMG patients. Twelve OMG patients who accepted frontalis sling with frontalis orbicularis oculi muscle (FOOM) flap for blepharoptosis correction were reviewed. Patients' demographies, perioperative changes of the interpalpebral fissure height (IPFH), margin reflex distance 1 (MRD1), levator function (LF), and quality of life (QOL) score were evaluated. The duration of OMG ranged from 3 to 31 years. LF was normal in 6 patients, good in 5, and poor in 1. There is no significant change of LF before and after surgery. MRD1 improved significantly from -1.8 mm (range, 0 to -5 mm) preoperatively to 2.9 mm (range, 2-4 mm) postoperatively. IPFH improved significantly from 3.8 mm (range, 2-6 mm) preoperatively to 7.8 mm (range, 6-9 mm) postoperatively. Upper eyelid margin was above the pupil in all patients. QOL score improved significantly from 18.2 (range, 14-23) preoperatively to 5.8 (range, 0-10) postoperatively. Our report reveals that surgical correction of the blepharoptosis is effective for patients with intractable OMG and that frontalis suspension with FOOM flap is a valuable option because of its ready availability and pliability. All patients are satisfied with the results, especially the improvement of QOL.

    1) To evaluate the efficacy of, and problems with, intratympanic gentamicin injection (ITG) in medically intractable definite Ménière's disease (MD) and secondary endolymphatic hydrops (EH); and 2) to review the vestibular status and treatment options of intractable vertigo even after ITG. Retrospective case review and survey. 780 patients with definite MD and secondary EH were enrolled. Long-term outcomes and problems of applied treatment options including ITG and exploratory tympanotomy and gentamicin application (ETG) were analyzed. Of the 780 patients, 95 patients received ITG. Class A and B control of vertigo was achieved in 85 (89.5%) patients; two patients were class C and eight patients were class F (ETG: 6; labyrinthectomy: 1; vestibular neurectomy: 1). Among seven patients who received ETG including 1 patient who skipped ITG due to chronic otitis media, five patients improved to class A, showing a 71.4% success rate; and labyrinthectomies were performed subsequently in the two remaining patients. Vertigo was controlled (class A) in all the patients who received labyrinthectomies (n = 4) or vestibular neurectomy (n = 1). Eight patients (8.4%) experienced more than 10 dB worsening, and two patients (2.1%) progressed to bilateral Ménière's disease. ITG failed to control vertigo in 10.5% of cases. ETG may be a reasonable option to facilitate the delivery of gentamicin into the inner ear by direct application of gentamicin over the round window and the oval window. Labyrinthectomy and vestibular neurectomy still have roles in the era of ITG. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    Skeletal conditions are common causes of chronic pain and there is an unmet medical need for improved treatment options. Bone pain is currently managed with disease modifying agents and/or analgesics depending on the condition. Disease modifying agents affect the underlying pathophysiology...... of the disease and reduce as a secondary effect bone pain. Antiresorptive and anabolic agents, such as bisphosphonates and intermittent parathyroid hormone (1-34), respectively, have proven effective as pain relieving agents.

NSAIDs and opioids are widely employed in the treatment of bone pain. However, recent preclinical findings demonstrating a unique neuronal innervation of bone tissue and sprouting of sensory nerve fibers open for new treatment possibilities....

  1. A normal psychology of everyday pain.

    Science.gov (United States)

    Eccleston, C

    2013-01-01

    Proposed is a psychology of pain that focusses on normal psychological reactions to pain. A normal psychology of pain seeks to explain what normal people (those who would not meet any criteria for any psychological disorder) do when faced with pain. Herein, we focus on everyday pain defined as pain that is clinically unimportant that arises from normal everyday activity. Pain functions to interrupt current concerns and promote problem solving typically in the form of escape, pain management, or request for assistance. A model of analgesic problem solving is described. Focussing on pain as an interruption leads us to think about the purpose of analgesics in repairing attention and returning function. New endpoints for analgesic performance are offered. Similarly, a focus on pain as a motivation for analgesia demands that we understand how people self-medicate its relative success, and what influences patterns of self-medication. Finally, the problem of pain in children and adolescents, including self-medication in youth, is discussed. Although there is limited small-scale research on young people and their knowledge about analgesics, very little is known about their beliefs, attitudes to analgesics and their self-medication behaviour. Adolescents in most societies are left largely unguided. There is little child-specific communication about how to manage pain. Most children rely on parental knowledge, although increasingly the internet is becoming a source of advice for young people learning about analgesics. © 2012 Blackwell Publishing Ltd.

Here, we report on an exemplary case of a middle-aged woman who was referred to the Vulvovaginal Disease Clinic with debilitating vulvar burning and itching over the right labium majus that had been persisting for 2 years and was considered intractable. Careful history taking and clinical examination, followed by electrophysiological assessment through somatosensory evoked potentials was consistent with genitofemoral neuralgia, for which no obvious cause could be identified. Adequate pain relief was obtained with a serotonin–noradrenaline reuptake inhibitor and topical gabapentin cream. We briefly discuss the epidemiology, diagnosis, and treatment of genitofemoral neuralgia and provide a series of clues to guide clinicians in obtaining a presumptive diagnosis of specific neuropathic pain syndromes that may underlie chronic vulvar pain. We further aim to draw attention to the tremendous burden of chronic, unrecognized vulvar pain. Keywords: vulvar pain, genitofemoral nerve, neuropathic pain, vulvodynia, vulvar disease

    Despite improvements in endoscopic hemostasis and pharmacological therapies, upper gastrointestinal (UGI) ulcers repeatedly bleed in 10% to 20% of patients, and those without early endoscopic reintervention or definitive surgery might be at a high risk for mortality. This study aimed to identify the risk factors for intractability to initial endoscopic hemostasis. We analyzed intractability among 428 patients who underwent emergency endoscopy for bleeding UGI ulcers within 24 hours of arrival at the hospital. Durable hemostasis was achieved in 354 patients by using initial endoscopic procedures. Sixty-nine patients with Forrest types Ia, Ib, IIa, and IIb at the second-look endoscopy were considered intractable to the initial endoscopic hemostasis. Multivariate analysis indicated that age ≥70 years (odds ratio [OR], 2.06; 95% confidence interval [CI], 1.07 to 4.03), shock on admission (OR, 5.26; 95% CI, 2.43 to 11.6), hemoglobin <8.0 mg/dL (OR, 2.80; 95% CI, 1.39 to 5.91), serum albumin <3.3 g/dL (OR, 2.23; 95% CI, 1.07 to 4.89), exposed vessels with a diameter of ≥2 mm on the bottom of ulcers (OR, 4.38; 95% CI, 1.25 to 7.01), and Forrest type Ia and Ib (OR, 2.21; 95% CI, 1.33 to 3.00) predicted intractable endoscopic hemostasis. Various factors contribute to intractable endoscopic hemostasis. Careful observation after endoscopic hemostasis is important for patients at a high risk for incomplete hemostasis.

  5. Practical statistics in pain research.

    Kim, Tae Kyun

    2017-10-01

    Pain is subjective, while statistics related to pain research are objective. This review was written to help researchers involved in pain research make statistical decisions. The main issues are related with the level of scales that are often used in pain research, the choice of statistical methods between parametric or nonparametric statistics, and problems which arise from repeated measurements. In the field of pain research, parametric statistics used to be applied in an erroneous way. This is closely related with the scales of data and repeated measurements. The level of scales includes nominal, ordinal, interval, and ratio scales. The level of scales affects the choice of statistics between parametric or non-parametric methods. In the field of pain research, the most frequently used pain assessment scale is the ordinal scale, which would include the visual analogue scale (VAS). There used to be another view, however, which considered the VAS to be an interval or ratio scale, so that the usage of parametric statistics would be accepted practically in some cases. Repeated measurements of the same subjects always complicates statistics. It means that measurements inevitably have correlations between each other, and would preclude the application of one-way ANOVA in which independence between the measurements is necessary. Repeated measures of ANOVA (RMANOVA), however, would permit the comparison between the correlated measurements as long as the condition of sphericity assumption is satisfied. Conclusively, parametric statistical methods should be used only when the assumptions of parametric statistics, such as normality and sphericity, are established.

    To date, there is limited understanding of the role of the precuneus. fMRI studies have suggested its involvement in a wide spectrum of highly integrated tasks, including spatially-guided behaviour, visuo-spatial imagery, and consciousness. We present a patient with intractable parietal lobe epilepsy arising from a lesion localized to the right precuneus. Two seizure types with distinct semiologies were captured on video-EEG monitoring. The first type consisted of an urge described as a "feeling of wanting to move". On video analysis, the patient is seen to turn his head and body to his left. He remains conscious, he is able to answer questions and when asked, he can look to his right. This seizure was associated with an ictal pattern localized to the right parieto-occipital region. The second seizure type consisted of reading-induced visual distortion with macropsia and micropsia. Interictally, intermittent rhythmic slowing and spikes were seen and localized to the parietal midline and the right parieto-occipital regions. Our patient's seizures are positive phenomena of the right precuneus and its related processing network. They represent unique seizure semiologies that offer further insight into the role of the precuneus in spatial awareness, visuo-spatial processing and consciousness.

  7. Pain channelopathies

    2010-01-01

    Pain remains a major clinical challenge, severely afflicting around 6% of the population at any one time. Channelopathies that underlie monogenic human pain syndromes are of great clinical relevance, as cell surface ion channels are tractable drug targets. The recent discovery that loss-of-function mutations in the sodium channel Nav1.7 underlie a recessive pain-free state in otherwise normal people is particularly significant. Deletion of channel-encoding genes in mice has also provided insights into mammalian pain mechanisms. Ion channels expressed by immune system cells (e.g. P2X7) have been shown to play a pivotal role in changing pain thresholds, whilst channels involved in sensory transduction (e.g. TRPV1), the regulation of neuronal excitability (potassium channels), action potential propagation (sodium channels) and neurotransmitter release (calcium channels) have all been shown to be potentially selective analgesic drug targets in some animal pain models. Migraine and visceral pain have also been associated with voltage-gated ion channel mutations. Insights into such channelopathies thus provide us with a number of potential targets to control pain.

    Full Text Available Neuropathic pain is the expression of a dysfunction or primary lesion of a nerve in the peripheral or central nervous system, or both, rather than the biological signal transmitted by the nerve following peripheral nociceptor activation. It represents about 20% of all painful syndromes, with an estimated prevalence of 1.5%, however is actual incidence is hard to pinpoint due to the difficulties encountered in distinguishing it from chronic pain, of which it represents a significant percentage, on account of the not infrequent concurrence of conditions. It is crucial to recognise the variety of symptoms with which it can present: these can be negative and positive and, in turn, motor, sensitive and autonomic. In public health terms, it is important to emphasise that the diagnosis of neuropathic pain does not in most cases require sophisticated procedures and does not therefore weigh on health expenditure. In clinical practice, a validated scale (the LANSS is mentioned is useful for identifying patients presenting neuropathic pain symptoms. Therapy is based on three categories of medication: tricyclic antidepressants, anti-epileptics and opioids at high doses: neuropathic pain has a bad reputation for often resisting common therapeutic approaches and responding less well that nociceptor pain to monotherapy. Therapeutic strategies are all the more adequate the more they are based on symptoms and therefore on the pain generation mechanisms, although the recommendations are dictated more by expert opinions that double-blind randomised trials.

  15. The Biochemical Origin of Pain: The origin of all Pain is Inflammation and the Inflammatory Response. PART 2 of 3 –Inflammatory Profile of Pain Syndromes

    Science.gov (United States)

    2009-01-01

    Every pain syndrome has an inflammatory profile consisting of the inflammatory mediators that are present in the pain syndrome. The inflammatory profile may have variations from one person to another and may have variations in the same person at different times. The key to treatment of Pain Syndromes is an understanding of their inflammatory profile. Pain syndromes may be treated medically or surgically. The goal should be inhibition or suppression of production of the inflammatory mediators and inhibition, suppression or modulation of neuronal afferent and efferent (motor) transmission. A successful outcome is one that results in less inflammation and thus less pain. We hereby describe the inflammatory profile for several pain syndromes including arthritis, back pain, neck pain, fibromyalgia, interstitial cystitis, migraine, neuropathic pain, complex regional pain syndrome / reflex sympathetic dystrophy (CRPS/RSD), bursitis, shoulder pain and vulvodynia. These profiles are derived from basic science and clinical research performed in the past by numerous investigators and will be updated in the future by new technologies such as magnetic resonance spectroscopy. Our unifying theory or law of pain states: The origin of all pain is inflammation and the inflammatory response. The biochemical mediators of inflammation include cytokines, neuropeptides, growth factors and neurotransmitters. Irrespective of the type of pain whether it is acute or chronic pain, peripheral or central pain, nociceptive or neuropathic pain, the underlying origin is inflammation and the inflammatory response. Activation of pain receptors, transmission and modulation of pain signals, neuro plasticity and central sensitization are all one continuum of inflammation and the inflammatory response. Irrespective of the characteristic of the pain, whether it is sharp, dull, aching, burning, stabbing, numbing or tingling, all pain arise from inflammation and the inflammatory response. We are proposing

    Caroline eFreitag

    2014-08-01

    Full Text Available Chronic pain presents a widespread and intractable medical problem. While numerous pharmaceuticals are used to treat chronic pain, drugs that are safe for extended use and highly effective at treating the most severe pain do not yet exist. Chronic pain resulting from nervous system injury (neuropathic pain is common in conditions ranging from multiple sclerosis to HIV-1 infection to type II diabetes. Inflammation caused by neuropathy is believed to contribute to the generation and maintenance of neuropathic pain. Chemokines are key inflammatory mediators, several of which (MCP-1, RANTES, MIP-1α, fractalkine, SDF-1 among others have been linked to chronic, neuropathic pain in both human conditions and animal models. The important roles chemokines play in inflammation and pain make them an attractive therapeutic target. Peroxisome proliferator-activated receptors are a family of nuclear receptors known for their roles in metabolism. Recent research has revealed that PPARs also play a role in inflammatory gene repression. PPAR agonists have wide-ranging effects including inhibition of chemokine expression and pain behavior reduction in animal models. Experimental evidence suggests a connection between PPAR agonists' pain ameliorating effects and suppression of inflammatory gene expression, including chemokines. In early clinical research, one PPARα agonist, palmitoylethanolamide, shows promise in relieving chronic pain. If this link can be better established, PPAR agonists may represent a new drug therapy for neuropathic pain.

    Full Text Available Nevus sebaceous is known by its association with one or more secondary tumors, but more than three multiple tumors arising from a nevus sebaceous is extremely rare. A 67-year-old female presented with a light brown plaque on the back of her head that contained a dome-shaped black node and an erosive lesion. Histopathological examination showed atypical basaloid cells in the black node. At the periphery of that node, structures resembling follicular germs extruded from interlacing cords in the upper portion and tumor nests with sebocytes were in the lower portion. In the erosive lesion, papillated structures with an apocrine epithelium were observed. In the light brown plaque, enlargement of sebaceous lobules was noted. From those histopathological features, a diagnosis of syringocystadenoma papilliferum, sebaceoma, trichoblastoma and basal cell carcinoma arising from a nevus sebaceous was made. We discuss the rarity of multiple tumors arising from a nevus sebaceous.

  19. Pharmacological Regulation of Neuropathic Pain Driven by Inflammatory Macrophages

    Directory of Open Access Journals (Sweden)

    Norikazu Kiguchi

    2017-11-01

    Full Text Available Neuropathic pain can have a major effect on quality of life but current therapies are often inadequate. Growing evidence suggests that neuropathic pain induced by nerve damage is caused by chronic inflammation. Upon nerve injury, damaged cells secrete pro-inflammatory molecules that activate cells in the surrounding tissue and recruit circulating leukocytes to the site of injury. Among these, the most abundant cell type is macrophages, which produce several key molecules involved in pain enhancement, including cytokines and chemokines. Given their central role in the regulation of peripheral sensitization, macrophage-derived cytokines and chemokines could be useful targets for the development of novel therapeutics. Inhibition of key pro-inflammatory cytokines and chemokines prevents neuroinflammation and neuropathic pain; moreover, recent studies have demonstrated the effectiveness of pharmacological inhibition of inflammatory (M1 macrophages. Nicotinic acetylcholine receptor ligands and T helper type 2 cytokines that reduce M1 macrophages are able to relieve neuropathic pain. Future translational studies in non-human primates will be crucial for determining the regulatory mechanisms underlying neuroinflammation-associated neuropathic pain. In turn, this knowledge will assist in the development of novel pharmacotherapies targeting macrophage-driven neuroinflammation for the treatment of intractable neuropathic pain.

    Evaluate the seizure-reduction response and safety of mesial temporal lobe (MTL) brain-responsive stimulation in adults with medically intractable partial-onset seizures of mesial temporal lobe origin. Subjects with mesial temporal lobe epilepsy (MTLE) were identified from prospective clinical trials of a brain-responsive neurostimulator (RNS System, NeuroPace). The seizure reduction over years 2-6 postimplantation was calculated by assessing the seizure frequency compared to a preimplantation baseline. Safety was assessed based on reported adverse events. There were 111 subjects with MTLE; 72% of subjects had bilateral MTL onsets and 28% had unilateral onsets. Subjects had one to four leads placed; only two leads could be connected to the device. Seventy-six subjects had depth leads only, 29 had both depth and strip leads, and 6 had only strip leads. The mean follow-up was 6.1 ± (standard deviation) 2.2 years. The median percent seizure reduction was 70% (last observation carried forward). Twenty-nine percent of subjects experienced at least one seizure-free period of 6 months or longer, and 15% experienced at least one seizure-free period of 1 year or longer. There was no difference in seizure reduction in subjects with and without mesial temporal sclerosis (MTS), bilateral MTL onsets, prior resection, prior intracranial monitoring, and prior vagus nerve stimulation. In addition, seizure reduction was not dependent on the location of depth leads relative to the hippocampus. The most frequent serious device-related adverse event was soft tissue implant-site infection (overall rate, including events categorized as device-related, uncertain, or not device-related: 0.03 per implant year, which is not greater than with other neurostimulation devices). Brain-responsive stimulation represents a safe and effective treatment option for patients with medically intractable epilepsy, including patients with unilateral or bilateral MTLE who are not candidates for

    Statistical parametric mapping (SPM) quantification and analysis has been successfully applied to functional imaging studies of partial epilepsy syndromes in adults. The present study evaluated whether localisation of the epileptogenic zone (determined by SPM) improves upon visually examined single-photon emission tomography (SPET) imaging in presurgical assessment of children with temporal lobe epilepsy (TLE) and frontal lobe epilepsy (FLE). The patient sample consisted of 24 children (15 males) aged 2.1-17.8 years (9.8±4.3 years; mean±SD) with intractable TLE or FLE. SPET imaging was acquired routinely in presurgical evaluation. All patient images were transformed into the standard stereotactic space of the adult SPM SPET template prior to SPM statistical analysis. Individual patient images were contrasted with an adult control group of 22 healthy adult females. Resultant statistical parametric maps were rendered over the SPM canonical magnetic resonance imaging (MRI). Two corresponding sets of ictal and interictal SPM and SPET images were then generated for each patient. Experienced clinicians independently reviewed the image sets, blinded to clinical details. Concordance of the reports between SPM and SPET images, syndrome classification and MRI abnormality was studied. A fair level of inter-rater reliability (kappa=0.73) was evident for SPM localisation. SPM was concordant with SPET in 71% of all patients, the majority of the discordance being from the FLE group. SPM and SPET localisation were concordant with epilepsy syndrome in 80% of the TLE cases. Concordant localisation to syndrome was worse for both SPM (33%) and SPET (44%) in the FLE group. Data from a small sample of patients with varied focal structural pathologies suggested that SPM performed poorly relative to SPET in these cases. Concordance of SPM and SPET with syndrome was lower in patients younger than 6 years than in those aged 6 years and above. SPM is effective in localising the potential

    Sickle cell disease (SCD) is one of the most common inherited diseases worldwide. The disease is characterized by chronic hemolytic anemia, as well as acute and chronic complications. One of the most intractable problems encountered by children with SCD is the painful episode that results from tissue ischemia due to vaso-occlusion. Pain related to SCD is unique among pain syndromes due to the unpredictable, recurrent, and often persistent nature of the disease, as well as the recurring and essential need for the use of opioids. Painful vaso-occlusive episodes (VOE) are a principal cause of morbidity and account for a significant number of emergency department and hospital admissions. When untreated or inadequately managed, the pain of VOE may cause both short- and long-term consequences. Despite the fact that pain is an almost universal feature of the disease, children with SCD may form one of the most undertreated and understudied populations. One of the factors contributing to poor pain management is conflicting perceptions between patients, their families, and healthcare professionals about pain that is reported and analgesia that is required. Pain management guidelines have recently been published in an effort to overcome barriers in the assessment and management of pain related to SCD. Although there is considerable variability in the way SCD pain is managed, the standard treatment protocol for painful episodes has been rest, rehydration, and analgesia. However, pain control for children with SCD is often a difficult and complex process, and one that requires frequent systematic pain assessments and continuous adjustment of comfort measures, especially analgesics. There are a variety of analgesic agents to choose from, such as acetaminophen (paracetamol), oral or parenteral nonsteroidal anti-inflammatory drugs, and oral or parenteral opioids. Each of these options has advantages and disadvantages to their use. Continuous infusions of analgesics and patient

    The hindfoot is the part of the foot which is proximal to the midtarsal joint. The obvious causes of pain are not considered (post-traumatic etiologies, sprains and fractures but also cutaneous lesions). The main etiologies on the subject are successively exposed by following the localization of the pain. Diffuse pains (ankle arthritis tarsal osteoarthritis, algodystrophy, calcaneo-navicular synostosis but also bone diseases like stress fractures, Paget disease or tumors). Plantar talalgia (Sever's disease, plantar fasciitis and entrapment neuropathies such as (esions of the medial calcaneal nerve, of the first branch of the plantar lateral nerve, medial plantar nerve and lateral plantar nerve). Posterior pains: calcaneal tendinopathy including peritendinitis, tendinosis, retro-calcaneal bursitis and pathology of the postero-lateral talar tuberosity. Medial pains: tendinopathies of the posterior tibial tendon and tendinopathy of the flexor hallucis longus tendon and tarsal tunnel syndrome. Lateral pains: fibularis tendinopathies including split lesions of the fibularis brevis tendon, displacement of the fibularis iongus tendon, sinus tarsi syndrome and finally thickenings of capsules and ligaments and ossifications localized under the tibial malleoli. Anterior pains: antero-inferior tibio-fibular ligament, anterior tibial tendinopathy and anterior impingment syndrome.

    Sacral insufficiency fractures are an important and treatable cause of severe back pain. Despite publication of several case reports since its original description in 1982, awareness of these injuries remains inadequate in emergency medicine. Most patients are elderly women presenting with intractable lower back pain. Postmenopausal osteoporosis is the most significant risk factor. Marked sacral tenderness is common. Neurologic impairment is rarely detectable. Routine radiography of the spine and pelvis is usually inconclusive. Computed tomography remains the diagnostic modality of choice. Treatment is usually conservative.

    We studied the pathophysiology of localized central pain and the surgical result of spinal cord stimulation. There were 10 cases; 7 males and 3 females from 24 to 77 years old. Pain was caused by peripheral nerve injury in one case, spinal cord injury in two cases and cerebrovascular disease (CVD) (thalamic pain) in 7 cases. All cases were treated by epidural spinal cord stimulation and followed from 0.8 to 8.8 years. Sufficient pain relief was achieved in one case of peripheral nerve and spinal cord injury and in 4 cases of CVD. Moderate pain control was achieved in 2 cases of CVD. In one each case of spinal cord injury and of CVD, pain control was ineffective. In cases with thalamic pain, we studied the correlation between the surgical result of spinal cord stimulation and the clinical features, MRI, fluoro-deoxyglucose (FDG)-positron emission tomography (PET), and somatosensory evoked potentials (SEP) findings before operation. MRI revealed a small to moderate sized lesion on the thalamus or putamen in each case. PET also showed decreased accumulation of FDG on the affected thalamus. In all cases without one fair responder to spinal cord stimulation, we could recognize definite SEP originating in the sensory cortex ipsilateral side to the CVD lesion during contralateral median or posterior tibial nerve stimulation. In the good responders, we could recognize SEP originating in the sensory cortex of the lesion side with less delayed latency or decreased amplitude than in the moderate responders. In this group, test stimulation with low voltage on the spinal cord evoked a sensory effect (paresthesia) over the painful part of the body. Spinal cord stimulation proved to be an effective treatment for localized central pain. In cases with localized central pain after CVD, we could expect to ameliorate the intractable pain in those cases in which SEP or spinal cord test stimulation revealed that the thalamo-cortical system was preserved.

    Management of intractable haematuria and obstructive urosepsis from upper tract urothelial carcinoma can be problematic in patients not suitable for surgery, chemotherapy or radiotherapy. Interventional radiology techniques provide alternative approaches in this setting, such as complete kidney embolization to cease urine output, percutaneous nephrostomy, antegrade injection of sclerotherapy agents and sterilisation of the upper collecting system. Related approaches have been successfully employed to sclerose renal cysts, lymphoceles, chyluria and intractable lower tract haemorrhage. No reports of percutaneous, antegrade sclerotherapy in the upper urinary tract have previously been published. We present a case of recurrent haematuria and obstructive urosepsis caused by invasive upper tract urothelial carcinoma in a non-operative patient, which was treated with renal embolisation and percutaneous upper tract urothelial sclerotherapy.

    Ahmed, Karman; Oas, Kimberly Hall; Mack, Kenneth J; Garza, Ivan

    2010-11-01

    In adults, botulinum toxin type A has been studied as a potentially effective treatment for chronic daily headache. For pediatric chronic daily headache, the literature evaluating efficacy of botulinum toxin type A is sparse, with no studies assessing tolerability. The purpose of this retrospective case series study was to assess tolerability and efficacy of botulinum toxin type A in the treatment of pediatric chronic daily headache. The series comprises 10 patients (ages 11-17 years) who received a standard 100-unit dose of onabotulinumtoxinA (trade name, Botox) for refractory chronic daily headache. Attention was given to therapeutic history, efficacy, and tolerability. The patients had attempted an average of 8.0 ± 2.40 S.D. therapies prior to botulinum toxin type A. Most patients reported adverse events from at least one of these prior medications. With botulinum toxin type A, four patients (40%) reported subjective but clinically meaningful relief, consisting of a decrease in headache intensity, and two patients additionally noted a decrease in headache frequency. The four responders noted improvements in quality of life. Three patients experienced minor adverse events from botulinum toxin type A. This case series suggests that botulinum toxin type A can be well tolerated and may be a useful therapeutic in pediatric patients with highly medically intractable chronic daily headache.

    2017-01-01

    Full Text Available A 55-year-old male patient received an anoplasty at infancy for low-type anorectal malformation, and intractable constipation was observed since. The patient presented with colitis at the emergency department. Computed tomography revealed feces with a megarectosigmoid of diameter 18 cm. Hirschsprung disease was suspected on the basis of the imaging findings. Therefore, a rectal biopsy was performed, which indicated the presence of normal ganglion cells. Bowel management was implemented with one large-volume enema to empty the huge rectal pouch daily. The patient was free of constipation and had an improved nutritional status with appropriate weight gain in 3 months. A laparoscopic Swenson pull-through was performed. The hospital course was uneventful. Enemas, loperamide, and water-soluble fibers were required for frequent soiling because of postoperative hypermotile colon. The treatments were weaned off gradually. At the latest follow-up (2 years postoperatively, the patient had regular voluntary bowel movements with complete bowel control.

  1. Use of SAMC for Bayesian analysis of statistical models with intractable normalizing constants

    KAUST Repository

    Jin, Ick Hoon

    2014-03-01

    Statistical inference for the models with intractable normalizing constants has attracted much attention. During the past two decades, various approximation- or simulation-based methods have been proposed for the problem, such as the Monte Carlo maximum likelihood method and the auxiliary variable Markov chain Monte Carlo methods. The Bayesian stochastic approximation Monte Carlo algorithm specifically addresses this problem: It works by sampling from a sequence of approximate distributions with their average converging to the target posterior distribution, where the approximate distributions can be achieved using the stochastic approximation Monte Carlo algorithm. A strong law of large numbers is established for the Bayesian stochastic approximation Monte Carlo estimator under mild conditions. Compared to the Monte Carlo maximum likelihood method, the Bayesian stochastic approximation Monte Carlo algorithm is more robust to the initial guess of model parameters. Compared to the auxiliary variable MCMC methods, the Bayesian stochastic approximation Monte Carlo algorithm avoids the requirement for perfect samples, and thus can be applied to many models for which perfect sampling is not available or very expensive. The Bayesian stochastic approximation Monte Carlo algorithm also provides a general framework for approximate Bayesian analysis. © 2012 Elsevier B.V. All rights reserved.

  2. A case report of a man on peritoneal dialysis having intractable hyponatremia.

    2018-03-01

    Hyponatremia is one of the most common electrolyte disorders in patients on peritoneal dialysis (PD). It can be associated with severe consequences, higher morbidity and mortality. Therefore, hyponatremia should be assessed and monitored more carefully in these patients. A 55-year-old male PD patient progressively developed intractable hyponatremia was admitted to our hospital. The observation that no significant salt was lost in kidney and PD drainage prompted us to seek the underlying reasons for malnutrition and chronic inflammation. And cancer and tuberculosis were further suspected, although the exact nature at last was not clearly determined due to the unfavorable prognosis. The hyponatremia can hardly be improved by adjusting ultrafiltration close to zero, increasing sodium intake from 2.5 g to 7g, and nutrition counselling to maintain protein intake 0.9-1.2 g/kg/day and calorie intake 27-35 kcal/kg/day. Due to poor general situation, he received tentative anti-tuberculosis treatment instead of surgery for intracranial space-occupying lesion. He died at home with conservative therapy. It highlighted the challenge for differential diagnosis and treatment in the hyponatremia on PD patient.

  3. Packing of renal fossa: Useful technique for intractable bleeding after open pyelolithotomy surgery

    Directory of Open Access Journals (Sweden)

    Mohinder Kumar Malhotra

    2012-01-01

    Full Text Available There is no documented study to indicate the role of prolonged packing of renal fossa (24 to 48 hours to control bleeding in life threating haemorrhage following open pyelolithotomy without compromise in the renal functions. On the contrary emergency nephrectomy was performed for intractable bleeding during renal stone surgery in peripheral hospitals. Several studies have shown the usefulness of temporary packing to control bleeding in liver injuries and following open heart operations. Packing of the renal fossa with laparotomy pads in unstable patients, and transferring the patient to the surgical intensive care unit (ICU is also described in trauma but not in controlling bleeding after open pyelolithotomy .This study comprises of three such patients whose kidneys were salvaged by a simple procedure of temporary packing of renal fossa for period of 24-48 hours who had developed life threatening haemorrhage after open pyelolithotomy. This technique is simple and worth trying especially for surgeons who are contemplating nephrectomy as prolonged packing has not lead to any compromise in renal functions. The aim of this manuscript is very limited and clear. Packing is not a licence to carry out open pyelolithotomy without proper expertise and local backup or resources. Principles of safe and ethical surgical practice should never be violated as it can lead to medico legal complications.

  4. INTERPLAY OF SOCIAL REPRESENTATIONS, TRAUMA AND VICTIMIZATION IN INTRACTABLE CONFLICTS: THE CASE OF THE CYPRUS CONFLICT

    Directory of Open Access Journals (Sweden)

    Cristiana Lavinia Bădulescu

    2017-12-01

    Full Text Available Intractable conflicts are conflicts that persist over a long period of time, resist various attempts of resolution, and present sporadic episodes of violence juxtaposed with periods of relative calm. Also, they contain a large share of psychosocial factors which lend to their uniqueness while also adding to their complexity. The Cypriot conflict is such a conflict. It has been on the agenda of the international community for over four decades, it has gone through a number of occasional violent episodes that fluctuated in frequency and intensity, and has resisted various peace mediation efforts. As a result, the conflicting parties remained locked in an adversarial relationship and fixed in terms of fundamental grievances. This paper aims to explore the interplay of social representations, trauma and victimization in the Cyprus conflict, and their implications on the prospects for its further settlement. Specifically, using discourse analysis as a research method, this paper analyses both the Greek-Cypriot and Turkish-Cypriot official discourse during 1983-2012 in order to see how the two parties represent the conflict, and whether past trauma and victimization influence their social representations. Close attention to the key themes emerging from the two parties’ official discourse helps to deepen understanding of the role and effect social representations, trauma and victimization play in the perpetuation of the Cyprus conflict.

  5. Patterns of verbal learning and memory in children with intractable temporal lobe or frontal lobe epilepsy.

    Fuentes, Amanda; Smith, Mary Lou

    2015-12-01

    The objective of this study was to provide a better understanding of the verbal learning and memory (VLM) patterns that might differentiate children with frontal lobe epilepsy (FLE) from children with temporal lobe epilepsy (TLE) and to examine the impact of variables thought to influence outcomes (seizure laterality, age at seizure onset, age at assessment, epilepsy duration, number of antiepileptic drugs). Retrospective analyses were carried out for children with intractable unilateral TLE (n=100) and FLE (n=27) who completed standardized measures of VLM entailing lists of single words or lists of word pairs. Mean intelligent quotients and VLM scores on single words fell within the average range for both groups, whereas scores fell within the low average to borderline range on word pairs. No significant overall differences in VLM were found between the group with TLE and the group with FLE. Older age at assessment and older age at seizure onset were generally associated with better VLM in both groups but were related to better performance in a number of indices in the group with TLE and only fewer intrusions in the group with FLE. The VLM profiles of children with TLE and FLE are generally similar. Older age at assessment and older age at seizure onset have a favorable impact on both groups but are related to better encoding, retrieval, and monitoring processes for the group with TLE and improved memory monitoring (i.e., as indicated by fewer intrusions) in the group with FLE.

    Tremor markedly reduces quality of life and causes a significant psychological burden for patients who are severely affected by this movement disorder. Pharmacologic and surgical treatments for tremor exist, but for patients who have failed medical therapy and are not surgical candidates, stereotactic radiosurgery is the only available treatment option. Of available stereotactic radiosurgical techniques for intractable tremor, the authors chose to evaluate the safety and efficacy of gamma knife stereotactic radiosurgical thalamotomy. In order to qualitatively synthesize available data a systematic review was conducted by searching MEDLINE (OvidSP 1946–January Week 1 2014) and Embase (OvidSP 1974–2014 January). The search strategy was not limited by study design or language of publication. All searches were conducted on January 7, 2014. Treatment efficacy, adverse outcomes, and patient deaths were reviewed and tabulated. Complications appeared months to years post procedure and most commonly consisted of mild contralateral numbness and transient hemiparesis. Rarely, more severe complications were reported, including dysphagia and death. Though no data from randomized controlled trials are available, our analysis of the literature indicates that unilateral gamma knife thalamotomy using doses from 130 to 150 Gy appears safe and well tolerated

    The coal fires, a global catastrophe for hundreds of years, have been proved extremely difficult to control, and hit almost every coal-bearing area globally. Meanwhile, underground coal fires contain tremendous reservoir of geothermal energy. Approximately one billion tons of coal burns underground annually in the world, which could generate ~1000 GW per annum. A game-changing approach, environmentally sound thermal energy extraction from the intractable natural coalfield fires, is being developed by utilizing the waste energy and reducing the temperature of coalfield fires at the same time. Based on the Seebeck effect of thermoelectric materials, the temperature difference between the heat medium and cooling medium was employed to directly convert thermal energy into clean electrical energy. By the time of December 2016, the power generation from a single borehole at Daquan Lake fire district in Xinjiang has been exceeded 174.6 W. The field trial demonstrates that it is possible to exploit and utilize the waste heat resources in the treated coal fire areas. It promises a significant impact on the structure of global energy generation and can also promote progress in thermoelectric conversion materials, geothermal exploration, underground coal fires control and other energy related areas.

    The accumulation of free radicals may lead to seizures and increase the risk of their recurrence. Glutathione peroxidase and superoxide dismutase are 2 major enzymes that are involved in antioxidative defense mechanisms. Selenium (Se), zinc (Zn), and copper (Cu) are important trace elements that participate in the structure of these enzymes. The purpose of this study was to evaluate the possible associations between trace elements and idiopathic intractable epilepsy (IIE) by comparing the levels of Se, Zn, and Cu between patients with IIE and healthy children. Our study was designed as a case-control study with 70 IIE patients and 60 healthy children who were matched for age, ethnicity, and socioeconomic status. The levels of serum Se, Zn, and Cu were measured with an atomic absorption spectrophotometer. The results were statistically analyzed with SPSS version 16.0. We found that the patients with IIE had significantly decreased levels of serum Se and Zn compared to those of the control group (p<0.05). We believe that this study presents the first reports of decreased levels of Se and Zn in patients with IIE. These results may provide new insights for delineating the etiological basis of IIE and its potential therapeutic options. Copyright © 2012. Published by Elsevier B.V.

  9. Use of the Ketogenic Diet to Treat Intractable Epilepsy in Mitochondrial Disorders

    Science.gov (United States)

    Paleologou, Eleni; Ismayilova, Naila; Kinali, Maria

    2017-01-01

    Mitochondrial disorders are a clinically heterogeneous group of disorders that are caused by defects in the respiratory chain, the metabolic pathway of the adenosine tri-phosphate (ATP) production system. Epilepsy is a common and important feature of these disorders and its management can be challenging. Epileptic seizures in the context of mitochondrial disease are usually treated with conventional anti-epileptic medication, apart from valproic acid. However, in accordance with the treatment of intractable epilepsy where there are limited treatment options, the ketogenic diet (KD) has been considered as an alternative therapy. The use of the KD and its more palatable formulations has shown promising results. It is especially indicated and effective in the treatment of mitochondrial disorders due to complex I deficiency. Further research into the mechanism of action and the neuroprotective properties of the KD will allow more targeted therapeutic strategies and thus optimize the treatment of both epilepsy in the context of mitochondrial disorders but also in other neurodegenerative disorders.

    Changes in the production of immunoglobulins and rheumatoid factors (RF's) were studied in 20 patients with intractable rheumatoid arthritis (RA) following total doses of 750 rad or 2,000 rad lymphoid irradiation. Over a 12 month follow up period there was no consistent change in absolute serum or synovial fluid levels, or in synovial membrane production of either total IgG, IgA or IgM, or the corresponding RF fractions. The in-vitro production of immunoglobulins and IgM RF by peripheral blood mononuclear cells was also unaltered, except for one patient who had a dramatic rise in IgM RF production. Over the same period there was a significant overall reduction in disease activity following both doses of radiotherapy. It is concluded that the clinical response which occurs following lymphoid irradiation is not due to a reduction in RF production. Furthermore, the production of RF's appears to be unaffected by the changes in T cell immunity which occur following lymphoid irradiation. (author)

    Twenty-six patients participated in a randomized, double-blind study of the efficacy of total lymphoid irradiation in the treatment of intractable rheumatoid arthritis. All 26 patients, for whom therapy with gold compounds and penicillamine had failed, would ordinarily have been considered candidates for cytotoxic or antimetabolite drug therapy. Thirteen patients randomly assigned to receive full-dose total lymphoid irradiation (2000 rad) and 11 patients assigned to receive control low-dose total lymphoid irradiation (200 rad) completed radiotherapy. Alleviation of joint disease activity was significantly greater in the high-dose group as judged by morning stiffness, joint tenderness, and functional assessment (global composite score) at 3 and 6 months after radiotherapy. The high-dose group had a marked reduction in both T-lymphocyte function and numbers, but this finding was not observed in the low-dose group. Complications seen in the high-dose but not low-dose group included transient neutropenia, thrombocytopenia, pericarditis, and pleurisy

    Resection of the hippocampus can cause verbal memory decline, especially in the pediatric population. Thus, preservation of the hippocampus can be crucial for the quality of life of children with intractable temporal lobe epilepsy (TLE) who are candidates for epilepsy surgery. We investigated techniques that determine whether the hippocampus is part of the epileptogenic zone and the outcomes of pediatric surgery aimed to spare the hippocampus. We accessed data of children with normal hippocampus on MRI, who underwent surgery for medically refractory TLE. To identify epileptogenic areas, electrocorticography was performed in patients with space occupying lesions adjacent to the hippocampus, and long term invasive monitoring in patients with nonlesional TLE. Postoperative seizure control was classified according to Engel I-IV; Class I indicates seizure-free. Eleven females and 11 males met study inclusion criteria; the mean age at surgery was 11.3 years. Cortical and hippocampal electrocorticography was performed in 15 patients and long term invasive hippocampal monitoring in seven. The hippocampus was preserved in 16 patients (73%) while hippocampectomy was performed in 6 (27%). At the end of a mean follow-up of 3.5 years, 94% (15/16) of the patients who did not undergo hippocampectomy were classified as Engel I, compared to 50% (3/6) who underwent hippocampectomy. Sparing the hippocampus in temporal lobe epilepsy surgery is possible with excellent seizure outcome, while using the proper intraoperative technique. Copyright © 2017 British Epilepsy Association.

  13. Parent use of cannabis for intractable pediatric epilepsy: Everyday empiricism and the boundaries of scientific medicine.

    Cannabis is an increasingly sought-after remedy for US children with intractable (biomedically uncontrollable) epilepsy. However, like other complementary-alternative medicine (CAM) modalities, and particularly as a federally illegal, stigmatized substance, it is unsanctioned by mainstream medicine. Parents are largely on their own when it comes to learning about, procuring, dispensing, and monitoring treatments. Exploring how they manage is crucial to better assist them. Moreover, it can illuminate how 'research' done on the ground by laypeople variously disrupts and reinforces lay-expert and science-non-science divides. To those ends, in 2016, 25 Southern California parents who used, had used, or sought to use cannabis pediatrically for epilepsy/seizures were interviewed regarding their evidentiary standards, research methods, and aims when trying the drug. Parents generally described their work as experimentation; they saw their efforts as adhering to authorized scientific practices and standards, and as contributing to the authorized medical cannabis knowledge base. Findings subverted assumptions, based on an outdated stereotype of CAM, that cannabis-using parents do not believe in biomedicine. Indeed, parents' desire for their children's biomedical demarginalization, combined with biomedical dependency and a high caregiver burden, fueled a collaborative stance. Implications for understanding the boundaries of science are explored, as are norms for parent agency as ill children's care managers, radicalization among people affected by contested illnesses, and the future of 'medical marijuana.'

    Intractable faecal incontinence (FI) and constipation is a challenging condition to manage in children. Transanal irrigation (TAI) is a non-operative treatment option. This study presents our experience with TAI with the aim of finding predictive factors of non-compliance. This is an outcome and quality of life (QoL) study of a prospectively maintained database of patients < 17 years old commenced on TAI for intractable FI/constipation between 2008 and 2014. Outcome measures were: (1) compliance-classified as non-adopter (use of TAI stopped within 1 month after commencement) or adopter; (2) functional outcome-classified as responder (totally continent or occasional soiling) or non-responder; (3) Rintala score; and (4) QoL score (PedsQL™ 4.0 Generic Core Scale). Analysis to determine predictive factors was also performed. 42 patients were started on TAI [74% male, median age of commencement was 7 (3-16) years]. Underlying diagnoses were: idiopathic constipation (62%), anorectal malformation (26%), Hirschsprung disease (5%), spina bifida (5%) and gastroschisis (2%). Median follow-up period was 14 (3-78) months. 24% were non-adopters. 84% of the adopters responded to treatment. Rintala scores (mean ± SD) pre- and post-TAI were 6.7 ± 3.5 and 11.2 ± 4.8, respectively (P < 0.001). QoL scores pre- and post-TAI were 55.6 ± 24.1 and 65.5 ± 23.7, respectively (P < 0.001). Median age at which TAI was commenced in the non-adopter and adopter group were 6 (IQR 4.5-8.25) and 8 (IQR 7-12), respectively (P = 0.008). TAI is a safe and effective treatment for intractable constipation/FI in children. If tolerated, it can significantly improve quality of life. Age and underlying diagnosis are important factors when recommending TAI to children with intractable FI/constipation.

    A 49-year-old man presented with shortness of breath on exertion, orthopnea, and chest pain. On transthoracic echocardiography, a myxomatous mass was seen in the left atrium. A diagnosis of atrial myxoma was made and the patient underwent urgent surgical intervention. At operation, the mass, which extended into the anterior leaflet of the mitral valve, was excised. Histopathologic examination showed a primary cardiac sarcoma arising within a preexisting atrial myxoma. The patient received no further treatment and died 7 months postoperatively. We report the first case of a malignant transformation of an atrial myxoma to a cardiac sarcoma. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    In intractable intergroup conflicts, groups often try to frame intergroup violence as legitimate through the use of emotional appeals. Two experiments demonstrate that outsiders' perception of which emotion conflict parties communicate influences the extent to which they legitimize their violence.

  14. Neonatal pain

    Walker, Suellen M

    2014-01-01

    Effective management of procedural and postoperative pain in neonates is required to minimize acute physiological and behavioral distress and may also improve acute and long-term outcomes. Painful stimuli activate nociceptive pathways, from the periphery to the cortex, in neonates and behavioral responses form the basis for validated pain assessment tools. However, there is an increasing awareness of the need to not only reduce acute behavioral responses to pain in neonates, but also to protect the developing nervous system from persistent sensitization of pain pathways and potential damaging effects of altered neural activity on central nervous system development. Analgesic requirements are influenced by age-related changes in both pharmacokinetic and pharmacodynamic response, and increasing data are available to guide safe and effective dosing with opioids and paracetamol. Regional analgesic techniques provide effective perioperative analgesia, but higher complication rates in neonates emphasize the importance of monitoring and choice of the most appropriate drug and dose. There have been significant improvements in the understanding and management of neonatal pain, but additional research evidence will further reduce the need to extrapolate data from older age groups. Translation into improved clinical care will continue to depend on an integrated approach to implementation that encompasses assessment and titration against individual response, education and training, and audit and feedback.

    Intractable epilepsies, that is, seizure disorders that do not respond to currently available therapies, are difficult, often tragic, neurological disorders. Na(+) channelopathies have been implicated in some intractable epilepsies, including Dravet syndrome (Dravet 1978), but little progress has been forthcoming in therapeutics. Here we examine a Drosophila model for intractable epilepsy, the Na(+) channel gain-of-function mutant para(bss1) that resembles Dravet syndrome in some aspects (parker et al. 2011a). In particular, we identify second-site mutations that interact with para(bss1), seizure enhancers, and seizure suppressors. We describe one seizure-enhancer mutation named charlatan (chn). The chn gene normally encodes an Neuron-Restrictive Silencer Factor/RE1-Silencing Transcription factor transcriptional repressor of neuronal-specific genes. We identify a second-site seizure-suppressor mutation, gilgamesh (gish), that reduces the severity of several seizure-like phenotypes of para(bss1)/+ heterozygotes. The gish gene normally encodes the Drosophila ortholog of casein kinase CK1g3, a member of the CK1 family of serine-threonine kinases. We suggest that CK1g3 is an unexpected but promising new target for seizure therapeutics.

    Despite the successful use of a ketogenic diet in pediatric epilepsy, its application in adults has been limited. The aim of this meta-analysis was to summarize the findings of relevant published studies in order to identify the efficacy of and compliance with a ketogenic diet and its main subtypes (i.e., classic ketogenic diet and modified Atkins diet) in adults with intractable epilepsy, and to provide useful information for clinical practice. Electronic searches of PubMed, EMBASE, Google Scholar, and the ISI Web of Science were conducted to identify studies of the efficacy of and patient compliance with a ketogenic diet in adults with intractable epilepsy; the included studies were reviewed. Meta-analyses were performed using STATA to determine combined efficacy rates and combined rates of compliance with the ketogenic diet and its main subtypes. In total, 12 studies qualified for inclusion, and data from 270 patients were evaluated.The results of the meta-analysis revealed combined efficacy rates of all types of ketogenic diet, a classical ketogenic diet, and a modified Atkins diet were 42%, 52%, and 34%, respectively; the corresponding combined compliance rates were 45%, 38%, and 56%. The results indicate that a ketogenic diet is a promising complementary therapy in adult intractable epilepsy, and that while a classical ketogenic diet may be more effective, adult patients are likely to be less compliant with it than with a modified Atkins diet.

    Objective: To investigate the hemodynamics of increasing portal venous pressure(PVP) in hepatocellular carcinoma patients complicated with hepatic arterioportal vein fistulas (HAPVF) and the diagnosis and therapy of intractable upper gastrointestinal hemorrhage caused by HAPVF. Methods: One hundred and fifteen cases of hepatocellular carcinoma with upper gastrointestinal hemorrhage were checked by hepatic arteriography and were treated through orifices embolization in cases with severe HAPCF by coils and/or ethanol. Results: Twenty-six out of 31 patients suffering intractable upper gastrointestinal hemorrhage have severe HAPVF (the main stem of portal veins are visible). However, there are only 15 patients with light HAPVF among the 84 patients who have mild upper gastrointestinal hemorrhage (the main stem of portal veins are invisible). After the embolization, all of the 26 patients who have severe HAPVF stopped bleeding. Among them, the main stem of hepatic arteries are occluded in 2 patients. Conclusion: The existence of severe HAPVF should be taken into consideration when intractable upper gastrointestinal hemorrhage occurs in hepatocellular carcinoma patients, and it can be diagnosed through hepatic artery DSA. Orifice embolization is the most effective method for such kind of hemorrhage. (authors)

    OBJECTIVE Thalamic stimulation can provoke electroencephalography (EEG) synchronization or desynchronization, which can help to reduce the occurrence of seizures in intractable epilepsy, though the underlying mechanism is not fully understood. Therefore, the authors investigated changes in EEG electrical activity to better understand the seizure-reducing effects of deep brain stimulation (DBS) in patients with intractable epilepsy. METHODS Electrical activation patterns in the epileptogenic brains of 3 patients were analyzed using classical low-resolution electromagnetic tomography analysis recursively applied (CLARA). Electrical activity recorded during thalamic stimulation was compared with that recorded during the preoperative and postoperative off-stimulation states in patients who underwent anterior thalamic nucleus DBS for intractable epilepsy. RESULTS Interictal EEG was fully synchronized to the β frequency in the postoperative on-stimulation period. The CLARA showed that electrical activity during preoperative and postoperative off-stimulation states was localized in cortical and subcortical areas, including the insular, middle frontal, mesial temporal, and precentral areas. No electrical activity was localized in deep nucleus structures. However, with CLARA, electrical activity in the postoperative on-stimulation period was localized in the anterior cingulate area, basal ganglia, and midbrain. CONCLUSIONS Anterior thalamic stimulation could spread electrical current to the underlying neuronal networks that connect with the thalamus, which functions as a cortical pacemaker. Consequently, the thalamus could modify electrical activity within these neuronal networks and influence cortical EEG activity by inducing neuronal synchronization between the thalamus and cortical structures.

    Purpose To determine the prevalence and identify predictors of medical intractability in children presenting with epilepsy prior to 36 months of age, and to assess the impact of medical intractability on long-term mortality and intellectual function. Methods Children with newly-diagnosed epilepsy prior to 36 months between 1980–2009 while resident in Olmsted County, MN were identified. Medical records were reviewed to collect epilepsy specific variables and long-term outcome data. Medically intractable epilepsy was defined as either (1) seizures greater than every 6 months at final follow-up and failure of two or more antiepileptic drugs for lack of efficacy, or (2) having undergone epilepsy surgery after failure of two or more antiepileptic drugs. Key Findings One hundred and twenty seven children with new-onset epilepsy were identified and followed for a median of 78 months. Medically intractable seizures occurred in 35%, and significant predictors on multivariate analysis were age ≤12 months at diagnosis (odds ratio [OR] 6.76, 95% confidence interval [CI] 2.00, 22.84, p=0.002), developmental delay at initial diagnosis of epilepsy (OR 20.03, 95% CI 3.49, 114.83, p=0.0008 ), neuroimaging abnormality (OR 6.48, 95% CI 1.96, 21.40, p=0.002) and focal slowing on initial EEG (OR 5.33, 95% CI 1.14, 24.88, p=0.03). Medical intractability occurred early in the course in most children, being seen in 61% by one year, and 93% by five years after initial diagnosis. Mortality was higher (20% vs 0%, p<0.001) and intellectual outcome poorer (p<0.001) if epilepsy was medically intractable. Significance One third of children presenting with epilepsy before 36 months will be medically intractable and significant predictors are identified. Medically intractable epilepsy is associated with increased mortality risk and significant intellectual disability. PMID:22738069

    Full Text Available A 50-year-old Japanese woman consulted the emergency department of our hospital for bleeding due to an intractable postoperative wound on the lower abdomen; the postoperative wound was owing to a laparoscopic cholecystectomy performed 1 year previously for acute cholecystitis. She presented with a painful ulcer on her right lower abdomen. She also presented with multiple scars, skin grafts on the extremities, and a missing left lower leg, the causes for all of which were unexplained. The results of her blood test were normal, except for the hemoglobin level. Histology of the skin biopsy specimen from the ulcer did not show any specific findings. The previous surgeon who had performed the laparoscopic cholecystectomy revealed that surgical wound dehiscence had occurred during her admission. After a body restraint had been applied, the ulcer improved. Medical records indicated that she had been admitted to the department of plastic surgery at our hospital for skin grafting of a leg ulcer. During that admission, she refused to consult with the department of psychiatry, although the staff suspected mental disorders. Therefore, we diagnosed her with cutaneous Munchausen syndrome. After vacuum-assisted closure (VAC therapy had been performed to prevent her from traumatizing the ulcer again, it rapidly became granulated and reepithelialized. Munchausen syndrome is characterized by feigning physical symptoms to seek attention. Patients self-inflict numerous lesions, keep getting admitted to different hospitals, and feign acute illness, usually spectacular diseases. VAC therapy may be effective for preventing patients with cutaneous Munchausen syndrome from traumatizing their wounds.

  3. The interrelationship of enterokinase and trypsin activities in intractable diarrhea of infancy, celiac disease, and intravenous alimentation.

    Enterokinase initiates digestion of protein by conversion of trypsinogen into trypsin. The interactions between enterokinase and trysin were investigated in 6 patients with intractable diarrhea of infancy and 34 children with celiac disease. The six infants between 2 and 3 months with intractable diarrhea of infancy had reduced mucosal enterokinase activity (9.5 +/- 4.8muM per gram of protein per minute) and reduced intraluminal trypsin activity (2.9 +/- 0.7muM per gram of protein per minute) as compared with healthy controls (109 +/- 34.2muM per gram of protein per minute and 14.3 +/- 5.8muM per gram of protein per minute) respectively. The activities of all enzymes returned toward normal following treatment with intravenous alimentation. The mucosal morphology of all pretreatment biopsies in all cases showed Grade III atrophy which improved. These findings suggest that enterokinase deficiency and reduced intraluminal trypsin activity in intractable diarrhea of infancy may be one of the contributing factors to protein malabsorption and consequent malnutrition. Thirty-four children with celiac disease were between the age of 9 months and 13 years. The 11 newly diagnosed patients with celiac disease demonstrated Grade III to IV atrophy of the mucosa. The 23 patients with treated celiac disease on a gluten-free diet showed a normal to Grade II atrophy. In both treated and untreated celiac disease the enterokinase activities and the intraluminal trypsin activity were within normal limits. The enterokinase activity in celiac disease is near normal in contrast to the marked reduction noted in intractable diarrhea of infancy even though the intestinal mucosa shows marked morphological alteration and the disaccharidase activities are greatly reduced in celiac disease. After a prolonged alimentary fast of up to 26 days on intravenous alimentation, two patients with intractable diarrhea of infancy showed improvement in the activities of enterokinase and trypsin.

    A carcinoma arising in a fibroadenoma is a rare event, which often entails a diagnostic challenge. The most common type is the lobular carcinoma and secondary a ductal carcinoma. We present an extremely rare case of malignant development of an invasive apocrine carcinoma in a complex fibroadenoma and underline the importance for clinicians to recognize the possibility of benign and malignant co-existence especially in older women.

    The present paper is concerned with the Hausdorff dimension of certain sets arising in Engel expansions. In particular, the Hausdorff dimension of the set is completely determined, where A n (x) can stand for the digit, gap and ratio between two consecutive digits in the Engel expansion of x and ϕ is a positive function defined on natural numbers. These results significantly extend the existing results of Galambos’ open problems on the Hausdorff dimension of sets related to the growth rate of digits.

    Tattooing, which involves the placement of ink into the skin, is an ancient decorative technique that has remained popular in modern society. Tattoos have long been known to cause cutaneous reactions, which include the emergence of neoplasms such as keratoacanthoma (KA) and squamous cell carcinoma (SCC) in tattooed areas of the skin. We review the clinical presentations, histology and treatment options for squamous neoplasms, primarily KA and SCC, arising in tattoos. © 2017 British Association of Dermatologists.

    A 46-year-old man, who had received the radiotherapy on his penile cancer about 8 years ago, suffered again from the tumor of his penile glans, which was thought to consist of recurrent cancer and postirradiation sarcoma. The patient underwent a radical amputation of penis combined with a postoperative chemotherapy, and is still alive wthout the recurrence of his tumor. Although more than 20 cases of penile sarcoma were reported in Japan, no case arising after radiotherapy was found.

    2003-12-15

    Acute pains requiring emergency management in oncology can be considered as physiopathological, somatic or visceral nociceptive pains. They are linked: to the tumour, indicating a modification of the tumoural evolution (necrosis, haemorrhage, fracture, acute obstruction of hollow organs or canals, occlusion, hydronephrosis); to the treatment: (inflammation of mucosal membranes, anusitis, post PL syndromes); and to invasive investigations. They are equally neuropathic, revealing an underlying threatened or confirmed medullary compression, or induced by neurotoxic chemotherapy. They are also analysed according to their mode of apparition: mechanical, arising as acute on chronic pain (the pre-fracture pain of metastases); insufficiency of the duration of therapeutic efficacity; an acute episode of neuropathic pain that is often lancing, unpredictable and inevitable. In all cases, it needs to be quantitatively and qualitatively analysed: evaluation, flavour of the symptoms; in order to choose one or a combination of adapted molecules, true antalgics or co-antalgics, antidepressants and anticonvulsants. To counteract this pain, medications with a short onset of action and a short half-life should be used to avoid side effects. These are administered in an intercurrent manner, initially starting at a low dose, modified daily according to the utilisation of supplementary doses. It is necessary to anticipate pain provoked by physical examinations or nursing care as much in the timing as the pharmacology, in using antalgics and/or anxiolytics with a short duration of action. Acutely emerging pains, whatever be their type, arising in the context of cancer and long-term pain are sensitising elements to all further pains, as they imprint in the memory, and are very negatively conditioned by the anguishing context of the illness.

  12. Treatment Options in Intractable Restless Legs Syndrome/Willis-Ekbom Disease (RLS/WED).

    2016-02-01

    Restless Legs Syndrome/Willis-Ekbom Disease (RLS/WED) is a common condition characterized by an irresistible urge to move the legs, concomitant with an unpleasant sensation in the lower limbs, which is typically relieved by movement. Symptoms occur predominantly at rest and prevail in the afternoon or evening. Treatment of patients with RLS/WED is indicated for those patients who suffer from clinically relevant symptoms. The management of mild forms of RLS/WED is mainly based on dopamine agonists (DA) therapy (including pramipexole and ropinirole) and α-2-δ calcium-channel ligand. Nevertheless, with passing of time, symptoms tend to become more severe and the patient can eventually develop pharmacoresistance. Furthermore, long-term treatment with dopaminergic agents may be complicated by the development of augmentation, which is defined by an increase in the severity and frequency of RLS/WED symptoms despite adequate treatment. Here, we discuss which are the best therapeutic options when RLS/WED becomes intractable, with a focus on advantages and side effects of the available medications. Prevention strategies include managing lifestyle changes and a good sleep hygiene. Different drug options are available. Switching to longer-acting dopaminergic agents may be a possibility if the patient is well-tolerating DA treatment. An association with α-2-δ calcium-channel ligand is another first-line approach. In refractory RLS/WED, opioids such as oxycodone-naloxone have demonstrated good efficacy. Other pharmacological approaches include IV iron, benzodiazepines such as clonazepam, and antiepileptic drugs, with different level of evidence of efficacy. Therefore, the final decision regarding the agent to use in treating severe RLS/WED symptoms should be tailored to the patient, taking into account the symptomatology, comorbidities, the availability of treatment and the history of the disease.

  13. Accounting for calibration uncertainty: Bayesian molecular dating as a "doubly intractable" problem.

    Science.gov (United States)

    Guindon, Stéphane

    2018-01-27

    This study introduces a new Bayesian technique for molecular dating that explicitly accommodates for uncertainty in the phylogenetic position of calibrated nodes derived from the analysis of fossil data. The proposed approach thus defines an adequate framework for incorporating expert knowledge and/or prior information about the way fossils were collected in the inference of node ages. Although it belongs to the class of "node-dating" methods, this method shares interesting properties with "tip-dating" techniques. Yet, it alleviates some of the computational and modeling difficulties that hamper tip-dating approaches. The influence of fossil data on the probabilistic distribution of trees is the crux of the matter considered here. More specifically, among all the phylogenies that a tree model (e.g., the birth death process) generates, only a fraction of them "agree" with the fossil data. Bayesian inference under the new model requires taking this fraction into account. However, evaluating this quantity is difficult in practice. A generic solution to this issue is presented here. The proposed approach relies on a recent statistical technique, the so-called exchange algorithm, dedicated to drawing samples from "doubly intractable" distributions. A small example illustrates the problem of interest and the impact of uncertainty in the placement of calibration constraints in the phylogeny given fossil data. An analysis of land plant sequences and multiple fossils further highlights the pertinence of the proposed approach. © The Author(s) 2018.

    Full text: 99 Tc m - Ethyl Cysteinate Diethylester (ECD) or Bicisate is a new radiopharmaceutical used for the assessment of cerebral perfusion. Unlike 99 Tc m Hexamethylpropylene Amine Oxime ( 99 Tc m - HMPAO) which is unstable and needs to be reconstituted immediately prior to injection, 99 Tc m -ECD is stable for up to eight hours following reconstitution. Therefore, 99 Tc m -ECD does not require mixing just prior to injection and is readily available on a daily inpatient basis to the epilepsy unit, facilitating earlier and faster injections, and the acquisition of true ictal studies. This is particularly important with patients who have extra temporal seizures which are typically brief in duration. 45 patients have undergone 99 Tc m -ECD studies for epilepsy in our department over a period of one year. Image acquisition routinely commences within two hours of injection, and consists of a 360 degree elliptical SPECT using an ADAC Dual Headed Gamma Camera. Patients undergo both ictal and inter ictal SPECT studies, and an MRI. Visual comparison of the ictal, inter ictal and MRI images is performed, as well as subtraction and co-registration. The SISCOM analysis technique is used which allows subtraction of the SPECTs and co registration with MRI. This has the advantage of improved specificity, sensitivity, and accurate anatomical localisation. The results of our experience with 99Tcm-ECD will be presented. In conclusion, we have found that 99 Tc m -ECD is ideally suited for peri-ictal SPECT studies as part of the pre-operative assessment of patients with intractable partial epilepsy.

    The etiology of secretory diarrhea in early life is often unclear. We report a Japanese boy who survived until 3 years of age, despite intractable diarrhea commencing soon after birth. The fecal sodium content was strikingly high (109 mmol/L [normal range, 27-35 mmol/L]) and the osmotic gap was decreased (15 mOsm/kg), consistent with the findings of congenital sodium diarrhea. We examined the mitochondrial respiratory chain function by blue native polyacrylamide gel electrophoresis (BN-PAGE) in-gel enzyme staining, BN-PAGE western blotting, respiratory chain enzyme activity assay, and immunohistochemistry. Liver respiratory chain complex (Co) I activity was undetectable, while other respiratory chain complex activities were increased (Co II, 138%; Co III, 153%; Co IV, 126% versus respective control activities). Liver BN-PAGE in-gel enzyme staining and western blotting showed an extremely weak complex I band, while immunohistochemistry showed extremely weak staining for the 30-kDa subunit of complex I, but normal staining for the 70-kDa subunit of complex II. The patient was, therefore, diagnosed with complex I deficiency. The overall complex I activity of the jejunum was substantially decreased (63% of the control activity). The immunohistochemistry displayed apparently decreased staining of the 30-kDa complex I subunit, together with a slightly enhanced staining of the 70-kDa complex II subunit in intestinal epithelial cells. These data imply that intestinal epithelial cells are also complex I-deficient in this patient. Complex I deficiency is a novel cause of secretory diarrhea and may act via disrupting the supply of adenosine triphosphate (ATP) needed for the maintenance of ion gradients across membranes.

    Embolization is a treatment option for intractable epistaxis; however, concerns regarding tissue necrosis, stroke and blindness persist in the literature. A retrospective review of patients from September 2010 to January 2016 treated with embolization for epistaxis was performed. No patient was excluded. Follow-up was 12 months and no patient was lost. 62 embolizations on 59 patients occurred. 21 cases were taking anticoagulants, P2Y12 inhibiting agents or had a systemic coagulopathy. Embolized territories typically involved bilateral distal internal maxillary arteries with unilateral or bilateral facial arteries with polyvinyl alcohol particles. 60 cases had procedural general anaesthesia. There were no major complications. Six died of unrelated causes. Of the surviving 53 patients, excluding the 3 patients with hereditary haemorrhagic telangiectasia, 5 had recurrent epistaxis post-embolization. Four were taking P2Y12 inhibiting and/or anticoagulants, none of which required surgery, prolonged packing or repeat embolization. This group had a propensity to recur compared with cases taking aspirin only or no antiplatelet/anticoagulant (77.8 vs 97.1%, p = 0.04). The fifth underwent repeat embolization after previously only having ipsilateral distal internal maxillary and facial arteries treated. Embolization for epistaxis is safe and effective. Of those who had recurrent epistaxis post embolization, most were taking P2Y12 inhibition and/or anticoagulation. We prefer bilateral distal internal maxillary artery and unilateral facial artery embolization under general anaesthesia for optimal safety and efficacy. Advances in knowledge: Embolization with this technique seems to facilitate superior outcomes without complications despite the large proportion of patients taking anticoagulating or P2Y12 inhibiting agents.

  17. Etiology and Pharmacology of Neuropathic Pain.

    Science.gov (United States)

    Alles, Sascha R A; Smith, Peter A

    2018-04-01

    Injury to or disease of the nervous system can invoke chronic and sometimes intractable neuropathic pain. Many parallel, interdependent, and time-dependent processes, including neuroimmune interactions at the peripheral, supraspinal, and spinal levels, contribute to the etiology of this "disease of pain." Recent work emphasizes the roles of colony-stimulating factor 1, ATP, and brain-derived neurotrophic factor. Excitatory processes are enhanced, and inhibitory processes are attenuated in the spinal dorsal horn and throughout the somatosensory system. This leads to central sensitization and aberrant processing such that tactile and innocuous thermal information is perceived as pain (allodynia). Processes involved in the onset of neuropathic pain differ from those involved in its long-term maintenance. Opioids display limited effectiveness, and less than 35% of patients derive meaningful benefit from other therapeutic approaches. We thus review promising therapeutic targets that have emerged over the last 20 years, including Na + , K + , Ca 2+ , hyperpolarization-activated cyclic nucleotide-gated channels, transient receptor potential channel type V1 channels, and adenosine A3 receptors. Despite this progress, the gabapentinoids retain their status as first-line treatments, yet their mechanism of action is poorly understood. We outline recent progress in understanding the etiology of neuropathic pain and show how this has provided insights into the cellular actions of pregabalin and gabapentin. Interactions of gabapentinoids with the α 2 δ -1 subunit of voltage-gated Ca 2+ channels produce multiple and neuron type-specific actions in spinal cord and higher centers. We suggest that drugs that affect multiple processes, rather than a single specific target, show the greatest promise for future therapeutic development. Copyright © 2018 by The Author(s).

  18. Chronic widespread pain in spondyloarthritis

    Directory of Open Access Journals (Sweden)

    F. Atzeni

    2014-06-01

    Full Text Available The pain associated with spondyloarthritis (SpA can be intense, persistent and disabling. It frequently has a multifactorial, simultaneously central and peripheral origin, and may be due to currently active inflammation, or joint damage and tissue destruction arising from a previous inflammatory condition. Inflammatory pain symptoms can be reduced by non-steroidal anti-inflammatory drugs, but many patients continue to experience moderate pain due to alterations in the mechanisms that regulate central pain, as in the case of the chronic widespread pain (CWP that characterises fibromyalgia (FM. The importance of distinguishing SpA and FM is underlined by the fact that SpA is currently treated with costly drugs such as tumour necrosis factor (TNF inhibitors, and direct costs are higher in patients with concomitant CWP or FM than in those with FM or SpA alone. Optimal treatment needs to take into account symptoms such as fatigue, mood, sleep, and the overall quality of life, and is based on the use of tricyclic antidepressants or selective serotonin reuptake inhibitors such as fluoxetine, rather than adjustments in the dose of anti-TNF agents or disease-modifying drugs.

    Shoulder pain is a frequent complaint encountered in the emergency setting. A brief review of shoulder anatomy and physical examination sets the foundation for evaluation of shoulder pain. Considerations of patient's age are helpful to predict injuries. Fractured clavicles are often seen in traumatic injuries in children and young adults, whereas fractures of the humeral head are more often seen in the elderly from traumatic injuries. Shoulder dislocations are more common in teens to fourth decade. This article reviews specific acute injuries, chronic conditions, and radiologic considerations of patients with shoulder complaints encountered in emergency settings.

    In emergency departments, chest pain is one of the leading motives of consultation. We thus consider it important to review aspects such as its classification, causes, and clinical profiles. Initial assessment should include a full clinical history comprising thorough anamnesis and physical examination. Adequate interpretation of auxiliary tests, ordered in accordance with suspected clinical conditions, should lead to accurate diagnosis. We highlight certain symptoms and clinical signs, ECG and X-ray findings, cardiac bio markers, arterial blood gases, and CT-scanning. Scores of severity and prognosis such as TIMI are assessed. Optimal treatment of the clinical conditions leading to chest pain depends on adequate initial approach and assessment.

    2009-02-01

    In this report, a case of metaplastic thymoma arising in a thymic cyst wall is discussed. The patient was a 61-year-old male whose chief complaint was sweating and chest pain. Imaging study revealed a mediastinal mass with right hemithoracic extension. He underwent surgical resection of the mass and remnants of the thymus. Histologic studies showed a primary thymic neoplasm with a biphasic histologic pattern composed of 2 distinct epithelial and stromal components arising in a thymic cyst wall. Immunohistochemically, the epithelial component was cytokeratin positive and focally reactive for EMA. Marked expression of EMA and vimentin was seen in spindle cells. Metaplastic thymoma is an extremely rare variant of primary thymic epithelial neoplasms with only a few cases reported in the literature.

    2012-08-01

    As a mechanisms-based classification of pain \\'peripheral neuropathic pain\\' (PNP) refers to pain arising from a primary lesion or dysfunction in the peripheral nervous system. Symptoms and signs associated with an assumed dominance of PNP in patients attending for physiotherapy have not been extensively studied. The purpose of this study was to identify symptoms and signs associated with a clinical classification of PNP in patients with low back (± leg) pain. Using a cross-sectional, between-subjects design; four hundred and sixty-four patients with low back (± leg) pain were assessed using a standardised assessment protocol. Patients\\' pain was assigned a mechanisms-based classification based on experienced clinical judgement. Clinicians then completed a clinical criteria checklist specifying the presence or absence of various clinical criteria. A binary logistic regression analysis with Bayesian model averaging identified a cluster of two symptoms and one sign predictive of PNP, including: \\'Pain referred in a dermatomal or cutaneous distribution\\

    Full Text Available Abstract Background Primary carcinoid tumor arising within mature teratoma of the kidney is extremely rare, and their clinicopathologic features are not well described. Our objective was to further define the clinical features and pathologic spectra of primary carcinoid tumor arising within mature teratoma of the kidney. Methods Six previously reported case reports were identified using MEDLINE and a subsequent bibliographic search of all pertinent reports and reviews was performed. We also searched the electronic medical archival records of our institution and identified one additional unreported case. Data were extracted on the demographics, predisposing factors, clinical presentation, radiographic features, gross pathology, microscopic pathology, immunophenotype, therapy, and outcome of each of these seven cases. Results Primary carcinoid tumor arising within mature teratoma of the kidney was found at a mean age of 41.4 years. Of the 7 cases, 3 were female and 4 were male. Two of the 7 cases (28.6% were associated with horseshoe kidney. It typically presented with abdominal pain without carcinoid syndrome. It typical radiologic appearance was well circumscribed partly calcified Bosniak II-III lesion. Histologically, the carcinoid tumor showed monotonous small round cells arranged in classic anastomosing cords/ribbons intermixed with solid nests. Surgery was curative, no additional treatment was required, no local recurrences occurred, and no metastases occurred in all 7 cases. The 3 cases with available outcome data were alive at the time of publication of their respective cases (mean, 5 months. Conclusion Primary carcinoid tumor arising within mature teratoma of the kidney is a rare tumor that typically presents with abdominal pain without carcinoid syndrome. It is not associated with local recurrence and metastasis, is surgically curable, and has excellent prognosis.

  11. An improved behavioural assay demonstrates that ultrasound vocalizations constitute a reliable indicator of chronic cancer pain and neuropathic pain

    Directory of Open Access Journals (Sweden)

    Selvaraj Deepitha

    2010-03-01

    Full Text Available Abstract Background On-going pain is one of the most debilitating symptoms associated with a variety of chronic pain disorders. An understanding of mechanisms underlying on-going pain, i.e. stimulus-independent pain has been hampered so far by a lack of behavioural parameters which enable studying it in experimental animals. Ultrasound vocalizations (USVs have been proposed to correlate with pain evoked by an acute activation of nociceptors. However, literature on the utility of USVs as an indicator of chronic pain is very controversial. A majority of these inconsistencies arise from parameters confounding behavioural experiments, which include novelty, fear and stress due to restrain, amongst others. Results We have developed an improved assay which overcomes these confounding factors and enables studying USVs in freely moving mice repetitively over several weeks. Using this improved assay, we report here that USVs increase significantly in mice with bone metastases-induced cancer pain or neuropathic pain for several weeks, in comparison to sham-treated mice. Importantly, analgesic drugs which are known to alleviate tumour pain or neuropathic pain in human patients significantly reduce USVs as well as mechanical allodynia in corresponding mouse models. Conclusions We show that studying USVs and mechanical allodynia in the same cohort of mice enables comparing the temporal progression of on-going pain (i.e. stimulus-independent pain and stimulus-evoked pain in these clinically highly-relevant forms of chronic pain.

    1979-03-01

    In this report, the volume of material and level of contained radioactive nuclides are tabulated for wastes arising from four fuel cycles which might be operated in CANDU-PHW (CANada Deuterium Uranium - Pressurized Heavy Water) reactors. The data presented, based on Canadian experience and/or studies, cover the range of conditioned waste volumes which could be expected from steady-state (no growth), CANDU-PHW-powered electrical generating systems. The wastes arising from operation and decommissioning of facilities in each phase of each fuel cycle are estimated. Each fuel cycle is considered to operate in isolation with the data given in terms of quantities per gigawatt-year of electricity produced. Three of the fuel cycles for which data are presented, the natural uranium once-through cycle, the plutonium-enriched uranium cycle (plutonium recycle) and the low-burnup uranium-enriched thorium cycle (thorium and uranium recycle), were studied by INFCE WG.7 (the International Nuclear Fuel Cycle Evaluation, Working Group 7) as fuel cycles 4, 5 and 6. The high-burnup uranium-enriched thorium cycle is included for comparison. INFCE WG.7 selected many common reference parameters which are applied uniformly to all seven INFCE WG.7 reference fuel cycles in determining waste arisings. Where these parameters differ from the data of Canadian origin given in the body of this report, the INFCE WG.7 data are given in an appendix. The waste management costs associated with operation of each INFCE WG.7 reference fuel cycle were calculated and compared by the working group. An arbitrary set of costing parameters and disposal technologies was selected by the working group for application to each of the reference fuel cycles. The waste management and disposal costs for the PHW reactor fuel cycles based on these arbitrary cost parameters are given in an appendix. (author)

    Full Text Available Dens evaginatus is a developmental anomaly that produces a tubercle on the occlusal surface of a tooth. It is found most frequently in the mandibular premolars. The occlusal tubercle easily causes occlusal interferences. Attrition or fracture of the tubercle can lead to pulpitis, pulp necrosis, periapical pathosis, and periapical infection. This case report illustrates the treatment of facial cellulitis arising from dens evaginatus with open apex. Calcium hydroxide was used for the apexification procedure. One year after canal obturation, radiography revealed no apical pathosis and the apical seal was evident.

    To determine the radiologic characteristics of malignant tumors arising from ovarian endometriosis. The radiologic findings of eleven patients with pelvic masses histologically confirmed as malignant ovarian tumors arising from endometriosis were retrospectively reviewed. All patients underwent MR, and six underwent ultrasonography. The findings were evaluated with regard to tumor size and shape, locularity, thickness and enhancement of the wall and septa, the presence of papillary nodule or solid portion, signal intensity of the locule, the presence of mass in contralateral ovary, ascites, local invasion, distant metastases, and the Pathologic diagnosis included clear cell carcinoma in six cases, endometrioid carcinoma in three, and mucinous cystadenocarcinoma of borderline malignancy and endometrial stromal sarcoma in one case each. Tumor size ranged from 8 to 20 (mean, 12.7)cm. The tumors were mixed in four cases, entirely cystic in three, predominantly cystic in three, and predominantly solid in one. Six cases were unilocular and five were multilocular. The wall and septa varied in thickness and regularity and were well enhanced in all but one case. In all cases papillary nodules or solid portions with similar enhancement to uterine myometrium were seen. On T1WI, the signal intensity of fluid was seen to be high in eight cases, low or intermediate in two, and of differing intensity in one. Ten cases showed high signal intensity on T2WI, whereas in one case in which high signal intensity was seen on T1WI, there was low signal intensity(shading). In three cases the contralateral ovary contained an endometrioma. Other features included ascites in seven cases and peritoneal seeding in one. Malignant ovarian tumors arising from endometriosis showed radiologic features of malignancy:they were larger than 10cm, there was enhancement of the wall and septa, and a papillary nodule or solid portion was present. However, the presence of hyperintense fluid, as seen on T1WI

    In addressing the area of safety goal implementation, the question of uncertainty arises. This report suggests that the Nuclear Regulatory Commission (NRC) should examine how other regulatory organizations have addressed the issue. Several examples are given from the chemical industry, and comparisons are made to nuclear power risks. Recommendations are made as to various considerations that the NRC should require in probabilistic risk assessments in order to properly treat uncertainties in the implementation of the safety goal policy. 40 references, 7 figures, 5 tables

    Full Text Available In this study, electrochemical methods and the digital holographic reconstruction technique were combined to detect the localized scratch-induced corrosion process of Alloy 690 in 0.50 mol dm-3 H2SO4 containing 0.10 mol dm-3 NaCl. The numerical reconstruction method has been proved to be an effective technique to detect changes of solution concentration. One can obtain direct information from the reconstructed images and capture subtle more revealing changes. It provides a method to detect localized corrosion arising from scratches.

    Mechanical circulatory support with extracorporeal membrane oxygenation (ECMO) and ventricular assist device has always been the optimal choice for treating the majority of medically intractable low cardiac output case. We retrospectively investigated our institution's outcomes and variables associated with a high risk of mortality. From 1999 to 2014, 86 patients who were of pediatric age or had grown-up congenital heart disease underwent mechanical circulatory support for medically intractable low cardiac output in our pediatric intensive care unit. Of these, 9 grown-up congenital heart disease patients were over 18 years of age, and the median age of the subject group was 5.82 years (range: 1 day to 41.6 years). A review of all demographic, clinical, and surgical data and survival analysis were performed. A total of 45 (52.3%) patients were successfully weaned from the mechanical assist device, and 25 (29.1%) survivors were able to be discharged. There was no significant difference in results between patients over 18 years and under 18 years of age. Risk factors for mortality were younger age (metabolic acidosis and increased levels of lactate, creatinine, bilirubin, or liver enzyme). The survival rate has improved since 2010 (from 25% before 2010 to 35% after 2010), when we introduced an upgraded oxygenator, activated heart transplantation, and also began to apply ECMO before the end-stage of cardiac dysfunction, even though we could not reveal significant correlations between survival rate and changed strategies associated with ECMO. Mechanical circulatory support has played a critical role and has had a dramatic effect on survival in patients with medically intractable heart failure, particularly in recent years. Meticulous monitoring of acid-base status, laboratory findings, and early and liberal applications are recommended to improve outcomes without critical complication rates, particularly in neonates with single ventricle physiology.

    Surgical treatment of psychiatric disease can be effective for some patients with severe, intractable disorders. However, few long-term studies using comprehensive psychiatric test evaluation of patients who have undergone surgery have been carried out. Stereotactic limbic leukotomy (subcaudate tractotomy and cingulotomy) was performed via radiofrequency thermocoagulation on 16 patients with intractable major affective disorders (bipolar). Patients were followed for 7 years, and nine complete psychiatric test evaluations were conducted before and after the procedure. Clinical outcomes were evaluated using the Current Global Psychiatric-Social Status Scale (CGPSS). In the 7-year follow-up, mean scores on the Hamilton Depression Rating Scale and the Beck Depression Inventory declined significantly from 42+/-5.76 to 20+/-11.98 (p0.1. Using the CGPSS, 68.8% of patients had a marked response (CGPSS of >or=3), 18.9% of patients had a possible response (CGPSS of 2), and 12.6% did not improve or became worse (CGPSS of 0 or 1). There was no surgical mortality and only three patients experienced temporary minor complications. Based on these nine comprehensive psychiatric test evaluations, limbic leukotomy is an effective procedure for long-term treatment of severe, intractable major affective disorders, with no significant side effects. The results of the psychiatric tests carried out during the 7 years of follow-up were constant and stable. The current findings demonstrate that depression, anxiety, and negative symptoms are significantly reduced by limbic leukotomy, but mania and active symptoms are not. Surgical intervention remains an important therapeutic option for the treatment of major affective disorders, and is probably underused.

    Children with chronic intractable constipation experience severe and long-lasting symptoms, which respond poorly to conventional therapeutic strategies. Detailed characterization of colonic motor patterns in such children has not yet been obtained. In 18 children with chronic intractable constipation, a high-resolution water-perfused manometry catheter (36 sensors at 1.5-cm intervals) was colonoscopically placed with the tip at the distal transverse colon. Colonic motor patterns were recorded for 2 h prior to and after a meal and then after colonic infusion of bisacodyl. These data were compared with previously published colonic manometry data from 12 healthy adult controls and 14 adults with slow-transit constipation. The postprandial number of the retrograde cyclic propagating motor pattern was significantly reduced in these children compared with healthy adults (children, 3.1 ± 4.7/h vs healthy adults, 34.7 ± 45.8/h; p constipated adults (4.5 ± 5.6/h; p = 0.9). The number of preprandial long-single motor patterns was significantly higher (p = 0.003) in children (8.0 ± 13.2/h) than in healthy adults (0.4 ± 0.9/h) and in constipated adults (0.4 ± 0.7/h). Postprandial high-amplitude propagating sequences (HAPSs) were rarely observed in children (2/18), but HAPS could be induced by bisacodyl in 16 of 18 children. Children with chronic intractable constipation show a similar impaired postprandial colonic response to that seen in adults with slow-transit constipation. Children may have attenuated extrinsic parasympathetic inputs to the colon associated with an increased incidence of spontaneous long-single motor patterns. © 2016 John Wiley & Sons Ltd.

    The neutrino mixing matrix U is in general of the form U=U_e^+ U_nu, where U_e arises from the diagonalization of charged leptons and U_nu is from the neutrino sector. We discuss the possibility that U_nu is nearly diagonal (in the lagrangian basis) and the observed mixing arises with good accuracy from U_e. We find that the fact that, in addition to the nearly maximal atmospheric mixing angle theta_{23}, the solar angle theta_{12} is definitely also large while at the same time the third mixing angle theta_{13} is small, makes the construction of a natural model of this sort considerably more complicated. We present an example of a natural model of this class. We also find that the case that U_nu is exactly of the bimixing type is severely constrained by the bound on theta_{13} but not excluded. We show that planned experimental searches for theta_{13} could have a strong impact on bimixing models.

    The neutrino mixing matrix U is in general of the form U=U{sub e}{sup {dagger}}U{sub {nu}}, where U{sub e} arises from the diagonalization of charged leptons and U{sub {nu}} is from the neutrino sector. We discuss the possibility that U{sub {nu}} is nearly diagonal (in the Lagrangian basis) and the observed mixing arises with good accuracy from U{sub e}. We find that the fact that, in addition to the nearly maximal atmospheric mixing angle {theta}{sub 23}, the solar angle {theta}{sub 12} is definitely also large while at the same time the third mixing angle {theta}{sub 13} is small, makes the construction of a natural model of this sort considerably more complicated.

    Full Text Available Here, we report an extremely rare case of trichoepithelioma (TE—a benign epithelial tumor originating from the outer root sheath of a hair follicle—arising in an ovarian mature cystic teratoma (MCT with fluorodeoxyglucose-positron emission tomography (FDG-PET findings. A 48-year-old Japanese woman presented to our hospital for her annual follow-up of adenomyosis. Ultrasonography and magnetic resonance imaging revealed a left ovarian tumor with irregular-shaped septum, which was suspicious of malignancy. However, tumor marker levels were within normal range. On FDG-PET, the maximum standardized uptake value (SUVmax of the tumor was 2.9. Laparotomy with left salpingooophorectomy was performed. Pathologic examination revealed the probability of TE, rather than basal cell carcinoma (BCC, arising in an ovarian MCT. After five years of follow-up, the patient had no sign of recurrence. The FDG-PET SUVmax was low in TE, as with other benign tumor. However, future investigation is needed to evaluate the findings of FDG-PET imaging in TE cases.

    Full Text Available Introduction. Tattoos have increasingly become accepted by mainstream Western society. As a result, the incidence of tattoo-associated dermatoses is on the rise. The presence of a poorly differentiated squamous cell carcinoma in an old tattooed skin is of interest as it has not been previously documented. Case Presentation. A 79-year-old white homeless man of European descent presented to the dermatology clinic with a painless raised nodule on his left forearm arising in a tattooed area. A biopsy of the lesion revealed a poorly differentiated squamous cell carcinoma infiltrating into a tattoo. The lesion was completely excised and the patient remains disease-free one year later. Conclusion. All previous reports of squamous cell carcinomas arising in tattoos have been well-differentiated low-grade type or keratoacanthoma-type and are considered to be coincidental rather than related to any carcinogenic effect of the tattoo pigments. Tattoo-associated poorly differentiated invasive carcinoma appears to be extremely rare.

    Full Text Available Sarcoma development has been associated with genetics, irradiation, viral infections, and immunodeficiency. Reports of sarcomas arising in the setting of prior trauma, as in burn scars or fracture sites, are rare. We report a case of a leiomyosarcoma arising in an arm that had previously been replanted at the level of the elbow joint following traumatic amputation when the patient was eight years old. He presented twenty-four years later with a 10.8 cm mass in the replanted arm located on the volar forearm. The tumor was completely resected and pathology examination showed a high-grade, subfascial spindle cell sarcoma diagnosed as a grade 3 leiomyosarcoma with stage pT2bNxMx. The patient underwent treatment with brachytherapy, reconstruction with a free flap, and subsequently chemotherapy. To the best of our knowledge, this is the first case report of leiomyosarcoma developing in a replanted extremity. Development of leiomyosarcoma in this case could be related to revascularization, scar formation, or chronic injury after replantation. The patient remains healthy without signs of recurrence at three-year follow-up.

    We report a case of a 46-year-old female who presented with a persistent lesion on the inferior right breast. The lesion was located within the scar from a breast augmentation procedure 12 years ago. The lesion had been treated as several conditions with no improvement. Biopsy revealed a superficial and nodular basal cell carcinoma, and the lesion was successfully removed with Mohs micrographic surgery. Basal cell carcinoma arising in a surgical scar is exceedingly rare with only 13 reported cases to date. This is the first reported case of basal cell carcinoma arising in a breast augmentation scar. We emphasize the importance of biopsy for suspicious lesions or those refractory to treatment, particularly those lesions that form within a scar.

    Full Text Available Ectopic hepatocellular carcinoma (HCC is a very rare clinical entity that is defined as HCC arising from extrahepatic liver tissue. This report presents a case of ectopic multiple HCC arising in the abdominal cavity. A 42-year-old otherwise healthy male presented with liver dysfunction at a general health checkup. Both HCV antibody and hepatitis B surface antigen were negative. Laboratory examination showed elevations in serum alpha-fetoprotein and PIVKA-II. Ultrasonography and computed tomography revealed multiple nodular lesions in the abdominal cavity with ascites without a possible primary tumor. Exploratory laparoscopy was performed, which revealed bloody ascites and multiple brown nodular tumors measuring approximately 10 mm in size that were disseminated on the perineum and mesentery. A postoperative PET-CT scan was performed but it did not reveal any evidence of a tumor in the liver. The tumors resected from the peritoneum were diagnosed as HCC. The present case of HCC was thought to have possibly developed from ectopic liver on the peritoneum or mesentery.

    OBJECTIVE Seizure onset within the insula is increasingly recognized as a cause of intractable epilepsy. Surgery within the insula is difficult, with considerable risks, given the rich vascular supply and location near critical cortex. MRI-guided laser interstitial thermal therapy (LiTT) provides an attractive treatment option for insular epilepsy, allowing direct ablation of abnormal tissue while sparing nearby normal cortex. Herein, the authors describe their experience using this technique in a large cohort of children undergoing treatment of intractable localization-related epilepsy of insular onset. METHODS The combined epilepsy surgery database of Cook Children's Medical Center and Dell Children's Hospital was queried for all cases of insular onset epilepsy treated with LiTT. Patients without at least 6 months of follow-up data and cases preoperatively designated as palliative were excluded. Patient demographics, presurgical evaluation, surgical plan, and outcome were collected from patient charts and described. RESULTS Twenty patients (mean age 12.8 years, range 6.1-18.6 years) underwent a total of 24 LiTT procedures; 70% of these patients had normal findings on MRI. Patients underwent a mean follow-up of 20.4 months after their last surgery (range 7-39 months), with 10 (50%) in Engel Class I, 1 (5%) in Engel Class II, 5 (25%) in Engel Class III, and 4 (20%) in Engel Class IV at last follow-up. Patients were discharged within 24 hours of the procedure in 15 (63%) cases, in 48 hours in 6 (24%) cases, and in more than 48 hours in the remaining cases. Adverse functional effects were experienced following 7 (29%) of the procedures: mild hemiparesis after 6 procedures (all patients experienced complete resolution or had minimal residual dysfunction by 6 months), and expressive language dysfunction after 1 procedure (resolved by 3 months). CONCLUSIONS To their knowledge, the authors present the largest cohort of pediatric patients undergoing insular surgery for

    Full Text Available Thalamic pain is a central neuropathic pain disorder which occurs after stroke. Its severe chronic pain is often intractable to pharmacotherapies and affects the patients’ activities of daily living (ADL and quality of life (QOL. Recently, spinal cord stimulation (SCS has been reported to be effective in relieving the pain of thalamic pain; however, the effect of SCS on gait performance in patients is unknown. Therefore, we evaluated the gait performance before and after SCS in a case with thalamic pain. A 73-year-old male with thalamic pain participated in this study. We evaluated the gait of the patient two times: before SCS insertion and after 6 days of SCS. At the second evaluation, we measured the gait in three conditions: stimulation off, comfortable stimulation, and strong stimulation. SCS succeeded in improving the pain from 7 to 2 on an 11-point numerical rating scale. Step frequency and the velocity of gait tended to increase between pre- and poststimulation periods. There were no apparent differences in gait among the three stimulation conditions (off, comfortable, and strong at the poststimulation period. SCS may be effective on gait in patients with thalamic pain.

  16. Systemic mast cell disease (SMCD) and bone pain. A case treated with radiotherapy

    International Nuclear Information System (INIS)

    Hesselmann, S.; Micke, O.; Schaefer, U.; Willich, N.

    2002-01-01

    Background: Systemic mast cell disease (SMCD) is a rare disease characterized by a multitopic proliferation of cytologically and/or functionally abnormal tissue mast cells. SMCD preferentially involves the skin, spleen, liver, lymph nodes and the bone marrow. The cause of SMCD is unknown. Bony pain, caused by mast cell infiltration of the marrow cavity, is present in up to 28% of cases and is frequently chronic and difficult to palliate with medical therapy. Case Report: We report one case of refractory bone pain in a 54-year-old female Caucasian patient with advanced SMCD and associated bony involvement, which was treated with radiotherapy for pain palliation. Between 1995 and 1998, the patient was irradiated at four different locations: 1) right shoulder and proximal right humerus, 2) both hands, 3) both knees, 4) left humerus with a total dose of 40 Gy in 2.0 or 2.5 Gy daily fractions. Results: Different results of pain palliation were achieved. In one location the pain was reduced for 55 months until her death due to disease progression, whereas in two other locations a pain control was maintained for 3 and 6 months after radiotherapy. In one location, no pain reduction was achieved. Severe side effects were not observed. Conclusion: Palliative radiotherapy has a role in the control of severe intractable bone pain in patients with advanced SMCD, though in some cases the effect may be short or incomplete. The observed palliation of pain can even differ in the same patient. (orig.)

  17. The adjuvant use of lansoprazole, clonazepam and dimenhydrinate for treating intractable hiccups in a patient with gastritis and reflux esophagitis complicated with myocardial infarction: a case report

    Science.gov (United States)

    2013-01-01

    Background Hiccup (Singultus) is a sudden and involuntary contraction of the diaphragm followed by a sharp closure of the epiglottis which results in the production of a specific “hic” sound. Normally, hiccups are treated without intervention. Intractable hiccups occur rarely but are a disturbing symptom underlying other health related disorders. Case presentation We report the clinical case of a 67-year-old male patient with myocardial infarction accompanied by intractable hiccups during the course of 8 months, and who was non-responsive to chlorpromazine or metoclopramide, and baclofen; drugs routinely used to treat this condition. This sustained hiccup had severely restricted the patient's ability to intake food and sleep. To explore alternative treatments, we investigated the adjuvant administration of lansoprazole, dimenhydrinate and clonazepam in this patient. We discovered that this drug combination was capable of successfully terminating his intractable hiccups, with no further evidence of recurrence. No similar treatment is previously reported for intractable hiccups. We further suggest a hypothesis concerning a potential mechanism on the anti-hiccup effect of dimenhydrinate. Conclusion We identified that the adjuvant use of lansoprazole, clonazepam and dimenhydrinate was capable of attenuating the symptoms of our patient with intractable hiccups. PMID:23954069

    Children with intractable functional constipation (FC) may eventually require surgery, often guided by motility testing. However, there are no evidence-based guidelines for the surgical management of intractable FC in children. To assess the diagnostic and surgical approach of pediatric surgeons and pediatric gastroenterologists towards children with intractable FC. A survey was administered to physicians attending an international conference held simultaneously in Columbus (Ohio, USA) and Nijmegen (the Netherlands). The survey included 4 questions based on cases with anorectal and colonic manometry results. 74 physicians completed the questionnaire. Anorectal manometry was used by 70%; 52% of them would consider anal sphincter botulinum toxin injections for anal achalasia and 21% would use this to treat dyssynergia. Colonic manometry was used by 38%; 57% of them reported to use this to guide surgical decision-making. The surgical approach varied considerably among responders answering the case questions based on motility test results; the most commonly chosen treatments were antegrade continence enemas and anal botulinum injections. Surgical decision-making for children with intractable FC differs among physicians. There is a need for clinical guidelines regarding the role of anorectal and colonic manometry in surgical decision-making in children with intractable FC. Copyright © 2016 Elsevier Inc.

    Carcinoma ex mixed tumor is a mixed tumor in which a second neoplasm develops from the epithelial component that fulfills the criteria for malignancy. This tumor occurs frequently in the parotid glands. Individuals in whom carcinoma ex mixed tumor have a past history of benign mixed tumor. These lesions contain both a benign mixed tumor as well as a malignant neoplasm. We report a case of carcinoma ex mixed tumor which occurred in the parotid gland. A 67-year-old woman presented with movable right mass. She complained pain and facial paralysis. The clinical presentation, several diagnostic images, and histopathologic findings are presented.

    Chest wall contains a wide array of tissues ranging from soft tissues like skin and muscle to bone. A variety of sarcomas can present with a painful or painless mass, which often requires histological testing for diagnosis. Chest wall sarcomas are very rare entities which are often growing slow . A multidisciplinary team is necessary for the management of chest wall sarcomas. We present a case of a 30-year-old male with spindle cell sarcoma of the chest wall and he underwent wide local excision along with surgical reconstruction.

A variety of sarcomas can present with a painful or painless mass, which often requires histological testing for diagnosis. Chest wall sarcomas are very rare entities which are often growing slow . A multidisciplinary team is necessary for the management of chest wall sarcomas. We present a case of a 30-year-old male with spindle cell sarcoma of the chest wall and he underwent wide local excisi...

    Rauschning, D.

    1983-01-01

    The author discusses the problems arising in the field of nuclear waste management on account of the constitutional law. Especially the difficulties emanating from the conflict between the provisions of section 9a of the Atomic Energy Act and the provisions of constitutional law are dealt with in detail, referring to the monography of H. Hofmann, 'legal aspects of nuclear waste management'. The author comes to the conclusion that the reqquirements laid down in section 9a-9c of the Atomic Energy Act are in agreement with the Basic law. There is, he says, no unreasonable risk for future generations, as the provisions of the nuclear law provide for sufficient safety of sites and equipment selected for the final storage of nuclear waste, ensuring that radioactive leakage is excluded over long periods of time. In the second part of his lecture, the author discusses the problem of competency and delegation of authority with regard to the reprocessing of radioactive waste. (BW) [de

    The book presents, in a systematic manner, the optimal controls under different mathematical models in fermentation processes. Variant mathematical models – i.e., those for multistage systems; switched autonomous systems; time-dependent and state-dependent switched systems; multistage time-delay systems and switched time-delay systems – for fed-batch fermentation processes are proposed and the theories and algorithms of their optimal control problems are studied and discussed. By putting forward novel methods and innovative tools, the book provides a state-of-the-art and comprehensive systematic treatment of optimal control problems arising in fermentation processes. It not only develops nonlinear dynamical system, optimal control theory and optimization algorithms, but can also help to increase productivity and provide valuable reference material on commercial fermentation processes.

    Carcinosarcoma arising from uterine adenomyosis is extremely rare. We encountered such a patient and herein provide a review of the literature. A 56-year-old woman was referred for a huge pelvic tumor, suspected to be an advanced uterine leiomyosarcoma. Intraoperative inspection revealed a mass, mainly located in the uterine myometrium, invading the uterine serosa. The tumor had previously spontaneously ruptured and disseminated to the pelvic cavity. Pathological and immunohistochemical examination revealed an infiltrative pattern of biphasic tumor cells composed of endometrioid adenocarcinoma and a nonepithelial component with rhabdomyosarcomatous differentiation. Benign endometrial glands with stromal cells were found adjacent to the area of the carcinosarcoma. The endometrium and both ovaries and fallopian tubes were microscopically free of tumor cells. The final diagnosis was heterologous type carcinosarcoma with rhabdomyosarcomatous differentiation, originating from uterine adenomyosis. © 2015 Japan Society of Obstetrics and Gynecology.

    Full Text Available Syringocystadenoma papilliferum (SCAP is a rare, benign tumour with varied presentations that arises from the apocrine glands and at times can lead to a diagnostic dilemma. A 53-year-old male presented with a 40-year history of a scalp nodule and a recent 2-year change in its character, and a sanguinopurulent discharge. Examination revealed a 4 cm × 2 cm firm nodule upon left side of the scalp vertex, actively discharging pus and blood. No regional lymph nodes were noticeably palpable. Incision biopsy performed elsewhere showed evidence of a squamous cell carcinoma-in-situ. He underwent a wide local excision with a bilobed flap reconstruction. Histopathologically, the lesion was reported to be SCAP. On follow-up, the patient has since remained asymptomatic with an acceptable cosmetic recovery.

    Full Text Available Mixed germ cell tumors with non-germ cell malignant components rarely occur in the anterior mediastinum. We report a case of a 34-year-old man who presented with an anterior mediastinum mass. Mixed germ cell tumor was initially diagnosed based on the pathologic findings of germinoma on thoracoscopic biopsy and clinical findings of elevated serum a-fetoprotein and β-human chorionic gonadotropin. The patient received preoperative chemotherapy and subsequent complete resection of the residual tumor. Pathologic examination of the excised specimen showed predominantly malignant ganglioneuroma and small residual foci of teratoma. To our knowledge, this is the first reported case of a malignant ganglioneuroma arising from mediastinal mixed germ cell tumor.

    The presence of pseudosymmetry can cause problems in structure determination and refinement. The relevant background and representative examples are presented. It is not uncommon for protein crystals to crystallize with more than a single molecule per asymmetric unit. When more than a single molecule is present in the asymmetric unit, various pathological situations such as twinning, modulated crystals and pseudo translational or rotational symmetry can arise. The presence of pseudosymmetry can lead to uncertainties about the correct space group, especially in the presence of twinning. The background to certain common pathologies is presented and a new notation for space groups in unusual settings is introduced. The main concepts are illustrated with several examples from the literature and the Protein Data Bank

    The impairment in musculoskeletal structures in patients with low back pain (LBP) is often disproportionate to their complaint. Therefore, the need arises for exploration of alternative mechanisms contributing to the origin and maintenance of non-specific LBP. The recent focus has been on central nervous system phenomena in LBP and the pathophysiological mechanisms underlying the various symptoms and characteristics of chronic pain. Knowledge concerning changes in pain processing in LBP remains ambiguous, partly due to the diversity in the LBP population. The purpose of this study is to compare quantitative sensory assessment in different groups of LBP patients with regard to chronicity. Recurrent low back pain (RLBP), mild chronic low back pain (CLBP), and severe CLBP are compared on the one hand with healthy controls (HC), and on the other hand with fibromyalgia (FM) patients, in which abnormal pain processing has previously been reported. Cross-sectional study. Department of Rehabilitation Sciences, Ghent University, Belgium. Twenty-three RLBP, 15 mild CLBP, 16 severe CLBP, 26 FM, and 21 HC participated in this study. Quantitative sensory testing was conducted by manual pressure algometry and computer-controlled cuff algometry. A manual algometer was used to evaluate hyperalgesia as well as temporal summation of pain and a cuff algometer was used to evaluate deep tissue hyperalgesia, the efficacy of the conditioned pain modulation and spatial summation of pain. Pressure pain thresholds by manual algometry were significantly lower in FM compared to HC, RLBP, and severe CLBP. Temporal summation of pain was significantly higher in FM compared to HC and RLBP. Pain tolerance thresholds assessed by cuff algometry were significantly lower in FM compared to HC and RLBP and also in severe CLBP compared to RLBP. No significant differences between groups were found for spatial summation or conditioned pain modulation. No psychosocial issues were taken into account for this

    Pharyngocutaneous or esophagocutaneous fistula formation is not a rare complication after surgical treatment of head/neck cancer. In cases having developed such fistula, conservative treatment with local manipulation or surgical closure of the fistula using a local or pedicled flap is often possible. We recently encountered a case with an intractable gastrocutaneous fistula which occurred a long time after gastric pull-up reconstruction of the pharynx and esophagus. The patient was a 58-year-old female. As treatment for hypopharyngeal and thoracic esophageal cancers, the patient underwent total resections of the laryngopharynx and esophagus and gastric pull-up reconstruction of the esophagus. Postoperatively, 50 Gy radiation was applied to the neck. Although there was no recurrence of cancer, a salivary fistula above the tracheostomy occurred six years after surgery. Closure of the fistula with a local flap was attempted twice, but did not succeed. The fistula was then closed with a deltopectoral (DP) flap, but a fistula recurred five months later. Finally, by resecting the cervical segment of the pulled-up stomach, the esophagus was reconstructed successfully with a free jejunal graft. An intractable fistula should be replaced using tissue with rich blood flow, such as a free jejunal graft. (author)

    Epilepsy is associated with disruption of integration in distributed networks, together with altered localization for functions such as expressive language. The relation between atypical network connectivity and altered localization is unknown. In the current study we tested whether atypical expressive language laterality was associated with the alteration of large-scale network integration in children with medically-intractable localization-related epilepsy (LRE). Twenty-three right-handed children (age range 8-17) with medically-intractable LRE performed a verb generation task in fMRI. Language network activation was identified and the Laterality index (LI) was calculated within the pars triangularis and pars opercularis. Resting-state data from the same cohort were subjected to independent component analysis. Dual regression was used to identify associations between resting-state integration and LI values. Higher positive values of the LI, indicating typical language localization were associated with stronger functional integration of various networks including the default mode network (DMN). The normally symmetric resting-state networks showed a pattern of lateralized connectivity mirroring that of language function. The association between atypical language localization and network integration implies a widespread disruption of neural network development. These findings may inform the interpretation of localization studies by providing novel insights into reorganization of neural networks in epilepsy. Copyright © 2015 Elsevier Ltd.

    To investigate the effectiveness of unilateral posterior semicircular canal (PSCC)-plugging surgery for patients with intractable bilateral PSCC-type benign paroxysmal positional vertigo (P-BPPV). From July 2011 to December 2015, we diagnosed 136 patients with P-BPPV. Of these, 3 patients had bilateral P-BPPV, and in 2 of the 3, the condition had been refractory to conservative treatment for more than 1 year. We planned a staged PSCC-plugging surgery for these 2 patients; initially one side was treated, and the contralateral side was treated 6 months later. After the first surgery, both patients experienced improvement in symptoms of vertigo and nystagmus on the operated side and no change on the non-operated side. Patients underwent the Epley maneuver for the non-operated side. In one case, the non-operated side was cured. In the other case, although the P-BPPV was not completely resolved, the patient was satisfied with the result of unilateral surgery because he was now able to turn in bed to the operated side without vertigo. Before surgery, he had experienced vertigo when turning even slightly in bed. We propose that even unilateral PSCC-plugging surgery is effective for some patients with intractable bilateral P-BPPV.

    The long-term effects of the ketogenic diet, a high fat diet for treating intractable epilepsy, on resting energy expenditure (REE) are unknown. The aim of this study was to evaluate the impact of 15 months of ketogenic diet treatment on growth and REE in children with intractable epilepsy. Growth, body composition, and REE were assessed at baseline, 3 months and 15 months in 24 children (14 males, 10 females; mean age 5 y 6 mo [SD 26 mo], range 7 mo-6 y 5 mo), 10 with cerebral palsy [CP]). Fifteen were identified as ketogenic diet responders at 3 months and continued on the ketogenic diet until 15 months. These were compared to 75 healthy children (43 males, 32 females; mean age 6 y 3 mo [SD 21 mo] age range 2-9 y). REE was expressed as percentage predicted, growth as height (HAz) and weight (WAz) z-scores, and body composition as fat and fat free mass (FFM). HAz declined -0.2 and -0.6 from baseline to 3 months and 15 months respectively (p = 0.001), while WAz was unchanged. In ketogenic diet responders, FFM, age and CP diagnosis predicted REE (overall R(2) = 0.76, pketogenic diet, linear growth status declined while weight status and REE were unchanged. REE remained reduced in children with CP. © 2014 Mac Keith Press.

    We evaluated the technical aspect and efficacy of transcatheter arterial embolization (TAE) in cases of intractable postpartum bleeding by comparing the angiographic findings women patients according to their delivery pattern. Between July of 2003 and March of 2008, 55 female patients were enrolled in this study. Of the 55 patients, 36 underwent a vaginal delivery (group 1), whereas 19 underwent a cesarean section delivery (group 2). We retrospectively evaluated the angiographic findings and the embolization technique between groups, using a Pearson Chi-Square test. Medical records and telephone interview findings were also reviewed to evaluate the efficacy of TAE and the outcome of fertility. Significantly greater positive angiographic findings were found in group 2 (63.2%) relative to group 1 (30.6%). For positive angiographic findings, except for AVM, the embolization was performed using coil or glue with gelfoam. For the negative angiographic findings or AVM, the gelfoam was the only embolic agent used. In all patients except for one, bleeding stopped after embolization. Major complications occurred in 2 patients only, and included uterine synechia and perforation. All patients except for one recovered after menstruation. In total, four patients became pregnant and one patient delivered a healthy infant. Positive angiographic findings requiring embolization with coil or glue, as well as gelfoam, were more commonly encountered in group 2 than in group 1. Based on the outcome of the study group, TAE is a safe and effective treatment for intractable postpartum bleeding and is also useful for preserving fertility.

  18. The Biochemical Origin of Pain – Proposing a new law of Pain: The origin of all Pain is Inflammation and the Inflammatory Response PART 1 of 3 – A unifying law of pain

    Science.gov (United States)

    2009-01-01

    We are proposing a unifying theory or law of pain, which states: The origin of all pain is inflammation and the inflammatory response. The biochemical mediators of inflammation include cytokines, neuropeptides, growth factors and neurotransmitters. Irrespective of the type of pain whether it is acute or chronic pain, peripheral or central pain, nociceptive or neuropathic pain, the underlying origin is inflammation and the inflammatory response. Activation of pain receptors, transmission and modulation of pain signals, neuro plasticity and central sensitization are all one continuum of inflammation and the inflammatory response. Irrespective of the characteristic of the pain, whether it is sharp, dull, aching, burning, stabbing, numbing or tingling, all pain arise from inflammation and the inflammatory response. We are proposing a re-classification and treatment of pain syndromes based upon their inflammatory profile. Treatment of pain syndromes should be based on these principles: Determination of the inflammatory profile of the pain syndromeInhibition or suppression of production of the appropriate inflammatory mediators e.g. with inflammatory mediator blockers or surgical intervention where appropriateInhibition or suppression of neuronal afferent and efferent (motor) transmission e.g. with anti-seizure drugs or local anesthetic blocksModulation of neuronal transmission e.g. with opioid medication At the L.A. Pain Clinic, we have successfully treated a variety of pain syndromes by utilizing these principles. This theory of the biochemical origin of pain is compatible with, inclusive of, and unifies existing theories and knowledge of the mechanism of pain including the gate control theory, and theories of pre-emptive analgesia, windup and central sensitization.

    Although the pathological changes in osteoporotic bones are well established, the characterization of the osteoporotic pain and its appropriate treatment are not fully elucidated. We investigated the behavioral signs of cutaneous and deep musculoskeletal pain and physical function; time-dependent changes in bone mineral density (BMD) and the emergence of the behavioral phenotype; and the effects of pharmacological interventions having different mechanisms of action (chronic intraperitoneal administration of pamidronate [0.25 mg/kg, 5x/week for 5 weeks] versus acute treatment with intraperitoneal morphine [10 mg/kg] and pregabalin [100 mg/kg]) in a mouse model of ovariectomized or sham-operated mice 6 months following surgery. We observed reduced BMD associated with weight gain, referred cutaneous hypersensitivity, and deep musculoskeletal pain that persisted for 6 months. Chronic bisphosphonate treatment, 6 months after ovariectomy, reversed bone loss and hypersensitivity to cold, but other behavioral indices of osteoporotic pain were unchanged. While the efficacy of acute morphine on cutaneous pain was weak, pregabalin was highly effective; deep musculoskeletal pain was intractable. In conclusion, the reversal of bone loss alone is insufficient to manage pain in chronic osteoporosis. Additional treatments, both pharmacological and nonpharmacological, should be implemented to improve quality of life for osteoporosis patients. PMID:28299231

    Sacroiliac joint (SIJ) pain affects older adults with a prevalence of up to 20% among patients with chronic low back pain. While pain medication, joint blocks and denervation procedures achieve pain relief in most patients, some cases fail to improve. Our goal was to determine the effectiveness of SIJ peripheral nerve stimulation in patients with severe conservative therapy-refractory SIJ pain. Here we present 12 patients with severe conservative therapy-refractory pain receiving an SIJ peripheral nerve stimulation. Patient satisfaction, pain, and quality of life were evaluated by means of the International Patient Satisfaction Index (IPSI), visual analog scale (VAS), and Oswestry Disability Index 2.0 (ODI) using standard questionnaires. For stimulation we placed an eight-pole peripheral nerve electrode parallel to the SIJ. Two weeks postoperatively, our patients reported an average ODI reduction from 57% to 32% and VAS from 9 to 2.1. IPSI was 1.1. After six months, the therapy was rated as effective in seven out of eight patients reporting at that period. The average ODI was low at 34% (p = 0.0006), while the VAS index rose to 3.8 (p VAS 1.7 (p < 0.0001), and IPSI 1.3. We conclude that SIJ stimulation is a promising therapeutic strategy in the treatment of intractable SIJ pain. Further studies are required to determine the precise target group and long-term effect of this novel treatment method. © 2014 International Neuromodulation Society.

    From 2006 to 2013, 12 patients with severe epistaxis refractory to prior conservative and surgical therapy were treated by superselective embolization of nasal arteries. Supersoft platinum microcoils with smallest diameters were used as the sole embolic agent in all cases. Coils were applied far distally in a stretched position for obtaining ideal target vessel superselectivity. The objective of this study is to evaluate efficacy and complications of superselective coil embolization for treatment of severe intractable epistaxis and to discuss results from an otorhinolaryngologic and an interventional neuroradiologic point of view. Retrospectively, all epistaxis inpatients between 2006 and 2013 were identified and subdivided by form of treatment: conservative, surgical and interventional therapy. Medical records of interventionally treated patients were reviewed for demographics, medical history, risk factors, clinical data, complications and short-term success, and patients were followed up for long-term success. Mean follow-up was 37 months. In 12 patients, 14 embolizations were carried out, with short-term success in 9 patients (75%), while early post-interventional rebleeding occurred in 3 patients (25%). Of 9 patients with short-term success, 1 died during stay, 1 was lost to follow-up and 1 had minor re-bleeding after 30 months. Six patients had short-term and long-term success. Before the first embolization, 3 ± 1 conservative and/or surgical procedures had been undertaken. Length of stay was 12.8 ± 3.6 days. 8 patients (67%) received red cell concentrates. Most frequent complications were mucosal damage and nasal pain, but these were related to repeated packing and surgery. Typical embolic complications as neurological or visual impairment or soft tissue necrosis were not observed in any patient. From the otorhinolaryngologic point of view, surgery is the treatment of choice in severe refractory epistaxis, but in case of repeated failure, superselective

    We report the third case of eccrine syringofibroadenoma (ESFA) arising in peristomal skin. A 55-year-old man presented with a 15- x 10-cm pale pink verrucous, exophytic, intermittently tender plaque involving his ileostomy site. He had undergone proctocolectomy with ileostomy creation 33 years prior for ulcerative colitis. The clinical differential diagnosis included granulomatous dermatitis, infection (fungus or atypical mycobacterium), or neoplasm. A punch biopsy specimen was performed and showed ESFA. Although ESFA is considered to be benign, recent reports have demonstrated an association of ESFA with malignancy or malignant transformation of ESFA. Furthermore, ESFA and reported cases of ileostomy carcinoma share similar clinical symptoms at presentation including pain, irritation, ulceration, bleeding, and the presence of a fungating mass. The lesion was, therefore, excised in toto and the excisional specimen showed no evidence of malignancy. We speculate that ESFA is a reaction to chronic irritation and, analogous to other long-standing reactive processes such as lichen sclerosis or burn scar ulcers, may be associated with malignant transformation. Because of this possibility and the clinical overlap with ileostomy carcinoma, peristomal ESFA should be treated with complete excision. If it is not amenable to complete excision because of lesion size or anatomic complexity, generous sampling and close clinical follow-up are recommended.

    The CT scans showed a heterogeneously enhancing necrotic mass with numerous areas of coarse calcification, and this was located in the left side of the retroperitoneal space and involved the body and tail of the pancreas. Portal venography via the celiac axis also showed invasion of the splenic vein. It represents approximately 1% of all chondrosarcomas and it carries a poor prognosis. It can occur in extraskeletal locations and mainly in the soft tissues of the orbit, the cranial and spinal meningeal coverings and the lower limbs. To the best of our knowledge, there has been no reported case of primary extraskeletal mesenchymal chondrosarcoma of the pancreas. Only two instances of metastatic chondrosarcomas in the pancreas have been reported in the literature. We report here on a case of primary mesenchymal chondrosarcoma arising from the pancreas in a 41-year-old man. In summary, we present here a case of primary extraskeletal mesenchymal chondrosarcoma that arose from the pancreas. Radiologically, it manifested as a necrotic soft tissue mass with chondroid calcifications.

    Carcinomas arising in mature cystic teratomas of the ovaries from nine women were examined for the presence of p53 mutations. The nine tumors comprised six squamous cell carcinomas, one squamous cell carcinoma in situ, one undifferentiated small cell carcinoma, and one mucoepidermoid carcinoma. Abnormal nuclear accumulation of the p53 protein was observed in four of the tumors. Genomic DNA was extracted from formalin-fixed, paraffin-embedded tissue blocks and subjected to polymerase chain reaction (PCR) for specific amplification of the p53 gene exons 5-8, followed by direct chemiluminescence sequencing analysis. A frameshift mutation in exon 8 (codon 278, CCT > del T; stop at codon 344) was detected in one poorly differentiated squamous cell carcinoma. The samples were also evaluated for the possible association of 'benign' and 'malignant' types of human papillomavirus (HPV) by PCR using universal primer sets. None of the samples contained detectable HPV genome. These data suggest that p53 mutations are relatively uncommon in secondary carcinomas developing in ovarian dermoid cysts, although the number of samples studied was admittedly small.

    HIV-1 is present in anatomical compartments and bodily fluids. Most transmissions occur through sexual acts, making virus in semen the proximal source in male donors. We find three distinct relationships in comparing viral RNA populations between blood and semen in men with chronic HIV-1 infection, and we propose that the viral populations in semen arise by multiple mechanisms including: direct import of virus, oligoclonal amplification within the seminal tract, or compartmentalization. In addition, we find significant enrichment of six out of nineteen cytokines and chemokines in semen of both HIV-infected and uninfected men, and another seven further enriched in infected individuals. The enrichment of cytokines involved in innate immunity in the seminal tract, complemented with chemokines in infected men, creates an environment conducive to T cell activation and viral replication. These studies define different relationships between virus in blood and semen that can significantly alter the composition of the viral population at the source that is most proximal to the transmitted virus.

    Although radiotherapy has proven of great therapeutic value in the treatment of malignant tumors, it should also be borne in mind that radiation has a serious potential risk of giving rise to a secondary malignancy. We recently experienced 2 cases each of carcinoma and sarcoma arising in the irradiated areas long after radiation therapy for malignant tumors. In these 4 cases, 2 males and 2 females, the primary neoplastic diseases were squamous cell carcinoma, epidermoid carcinoma, carcinoma of unknown pathology and malignant lymphoma, and the secondary tumors were epidermoid carcinoma, squamous cell carcinoma, osteosarcoma and chondrosarcoma, respectively. The sites of occurrence of these malignancies were invariably in the maxillary region; the mean latent period was 15 years, aside from an infantile case with a latent period of 5 years. In view of the primary diseases being malignant tumors the following criteria were set up for the diagnosis of radiation-induced malignancies: (1) the site of occurrence is within the confines of a previously irradiated area, (2) the latent period is prolonged and (3) the malignancy occurs as a double tumor. Therapy was primarily by operation. The prognosis was exceedingly ominous, the average survival time being 22 months. This was probably and mainly because of rapidity of tumor growth. Thus, the secondary tumors had already spread back to inward by the time they were first discovered. This should be kept in mind during a long-term follow-up of patients receiving radiotherapy for malignancy. (author)

    The purpose of this study is to determine empirically the state of the art of the medical care, when healthcare personal is confronted with ethical dilemmas related with the care they give to the geriatric population. An observational, longitudinal, prospective and qualitative study was conducted by analyzing the correlation between healthcare personnel-patient relationship, and ethical judgments regarding dilemmas that arise in daily clinical practice with geriatric patients. Mexican healthcare personnel with current active practices were asked to write up an ethical dilemma that arose frequently or that had impacted their medical practice. From the narrative input, we were able to draw up a database with 421 dilemmas, and those corresponding to patients 60 years and older were selected (n = 54, 12.8 %). The axiological analysis of the narrative dilemmas of geriatric patients was made using dialectical empiricism. The axiological analysis values found most frequently were classified into three groups: the impact of healthcare, the roles of the physician, and refusal of therapy; the healthcare role of educator, caring for the patients' life and the risk of imminent death where the values found more often. The persistence and universality of certain dilemmas in geriatrics calls for awareness and requires a good training in the ethical discernment of these dilemmas. This would help to improve substantially the care and the life quality of this population.

    The purpose of physics is to describe nature from elementary particles all the way up to cosmological objects like cluster of galaxies and black holes. Although a unified description for all this spectrum of events is desirable, this would be highly impractical. To not get lost in unnecessary details, effective descriptions are mandatory. Here we analyze the dynamics that may emerge from a full quantum description when one does not have access to all the degrees of freedom of a system. More concretely, we describe the properties of the dynamics that arise from quantum mechanics if one has access only to a coarse-grained description of the system. We obtain that the effective maps are not necessarily of Kraus form, due to correlations between accessible and nonaccessible degrees of freedom, and that the distance between two effective states may increase under the action of the effective map. We expect our framework to be useful for addressing questions such as the thermalization of closed quantum systems, as well as the description of measurements in quantum mechanics.

    Full Text Available Abstract Background Lipomas are common benign soft tissue neoplasms but they are found very rarely in the deep lobe of parotid gland. Surgical intervention in these tumors is challenging because of the proximity of the facial nerve, and thus knowledge of the anatomy and meticulous surgical technique are essential. Case presentation A 71-year-old female presented with a large asymptomatic mass, which had occupied the left facial area for over the past fifteen years, and she requested surgical excision for a cosmetically better facial appearance. The computed tomography (CT scan showed a well-defined giant lipoma arising from the left deep parotid gland. The lipoma was successfully enucleated after full exposure and mobilization of the overlying facial nerve branches. The surgical specimen measured 9 × 6 cm in size, and histopathology revealed fibrolipoma. The patient experienced an uneventful recovery, with a satisfying facial contour and intact facial nerve function. Conclusion Giant lipomas involving the deep parotid lobe are extremely rare. The high-resolution CT scan provides an accurate and cost-effective preoperative investigative method. Surgical management of deep lobe lipoma should be performed by experienced surgeons due to the need for meticulous dissection of the facial nerve branches. Superficial parotidectomy before deep lobe lipoma removal may be unnecessary in selected cases because preservation of the superficial lobe may contribute to a better aesthetic and functional result.

    Multilevel self-assembly involving small structured groups of nano-particles provides new routes to development of functional materials with a sophisticated architecture. Apart from the inter-particle forces, the geometrical shapes and compatibility of the building blocks are decisive factors. Therefore, a comprehensive understanding of these processes is essential for the design of assemblies of desired properties. Here, we introduce a computational model for cooperative self-assembly with the simultaneous attachment of structured groups of particles, which can be described by simplexes (connected pairs, triangles, tetrahedrons and higher order cliques) to a growing network. The model incorporates geometric rules that provide suitable nesting spaces for the new group and the chemical affinity of the system to accept excess particles. For varying chemical affinity, we grow different classes of assemblies by binding the cliques of distributed sizes. Furthermore, we characterize the emergent structures by metrics of graph theory and algebraic topology of graphs, and 4-point test for the intrinsic hyperbolicity of the networks. Our results show that higher Q-connectedness of the appearing simplicial complexes can arise due to only geometric factors and that it can be efficiently modulated by changing the chemical potential and the polydispersity of the binding simplexes.

    The CT scans showed a heterogeneously enhancing necrotic mass with numerous areas of coarse calcification, and this was located in the left side of the retroperitoneal space and involved the body and tail of the pancreas. Portal venography via the celiac axis also showed invasion of the splenic vein. It represents approximately 1% of all chondrosarcomas and it carries a poor prognosis. It can occur in extraskeletal locations and mainly in the soft tissues of the orbit, the cranial and spinal meningeal coverings and the lower limbs.

    Full Text Available The prevalence of Barrett's esophagus (BE in Eastern countries is rising to match the prevalence in the West. However, a corresponding trend of BE-associated adenocarcinoma has yet to be observed in Asia. Historically, adenocarcinoma complicating BE has been considered a rare event in Taiwan. In the present report, we collected three Taiwanese cases of esophageal adenocarcinoma arising from BE. The first case was a 37-year-old man with an advanced cancer that developed on pre-existing BE after a 3-year interval without endoscopic surveillance. The second case was a 63-year-old man who presented with odynophagia and was found to have an ulcerative tumor centered on the characteristic Barrett's mucosa. The final case was a 44-year-old man who presented with gradual-onset dysphagia and weight loss, without typical reflux symptom. Our report emphasizes the need for an updated epidemiologic study to determine the incidence of BE-associated adenocarcinoma in Taiwan.

    Full Text Available Struma ovarii is an uncommon type of ovarian mature teratoma with a predominant thyroid component. The morphological spectrum of the thyroid tissue ranges from that of normal thyroid to proliferative adenoma-like lesions and thyroid-type carcinomas (malignant transformation. The histologic features of ovarian strumal lesions sometimes cause diagnostic problems due to the confusion with other types of ovarian neoplasms and the difficulty in the prediction of their clinical behavior. We report an extremely rare case of poorly differentiated thyroid carcinoma arising in struma ovarii. A 22-year-old woman presented with a 15 cm right ovarian mass. The tumor showed a predominantly tubular pattern which raised a differential diagnosis between endometrioid adenocarcinoma and Sertoli cell tumor. A review of the gross specimen with additional tissue sampling helped identify the teratomatous and strumal nature, with a support by immunohistochemical staining. Despite FIGO stage IA by optimal staging procedure and the absence of identifiable lymphovascular invasion, the patient developed pulmonary metastasis 15 months after surgery and died from the progression of the disease 7 years after the diagnosis. This case emphasizes the importance of macroscopic examination of the specimen and the awareness of this uncommon tumor in the differential diagnosis of ovarian neoplasms.

  16. Obesity, the endocannabinoid system, and bias arising from pharmaceutical sponsorship.

    Previous research has shown that academic physicians conflicted by funding from the pharmaceutical industry have corrupted evidence based medicine and helped enlarge the market for drugs. Physicians made pharmaceutical-friendly statements, engaged in disease mongering, and signed biased review articles ghost-authored by corporate employees. This paper tested the hypothesis that bias affects review articles regarding rimonabant, an anti-obesity drug that blocks the central cannabinoid receptor. A MEDLINE search was performed for rimonabant review articles, limited to articles authored by USA physicians who served as consultants for the company that manufactures rimonabant. Extracted articles were examined for industry-friendly bias, identified by three methods: analysis with a validated instrument for monitoring bias in continuing medical education (CME); analysis for bias defined as statements that ran contrary to external evidence; and a tally of misrepresentations about the endocannabinoid system. Eight review articles were identified, but only three disclosed authors' financial conflicts of interest, despite easily accessible information to the contrary. The Takhar CME bias instrument demonstrated statistically significant bias in all the review articles. Biased statements that were nearly identical reappeared in the articles, including disease mongering, exaggerating rimonabant's efficacy and safety, lack of criticisms regarding rimonabant clinical trials, and speculations about surrogate markers stated as facts. Distinctive and identical misrepresentations regarding the endocannabinoid system also reappeared in articles by different authors. The findings are characteristic of bias that arises from financial conflicts of interest, and suggestive of ghostwriting by a common author. Resolutions for this scenario are proposed.

  17. Poststroke Pain – but Multiple Pain Mechanisms

    2010-01-01

    Full Text Available A 42-year-old man presented with acute left hemiplegia due to a right frontotemporal hemorrhagic stroke and left-sided pain. While the initial presentation suggested central poststroke pain, subsequent investigations also implicated heterotopic ossification of the left hip and amplification of previous low back pain by the new central pain. While heterotopic ossification has been commonly associated with brain injury, spinal cord injury or osseous injury, it is only rarely associated with stroke. Poststroke pain may be multifactorial, and discovering the pain mechanisms has important implications for treatment.

    The objective of this study was to estimate the expected cost-utility and cost-effectiveness of the ketogenic diet (KD), vague nerve stimulation (VNS) and care as usual (CAU), using a decision analytic model with a 5-year time horizon. A Markov decision analytical model was constructed to estimate the incremental costs, quality-adjusted life years (QALYs) and successfully treated patient (i.e. 50% or more seizure reduction) of the treatment strategies KD, VNS and CAU, from a health care perspective. The base case considered children with intractable epilepsy (i.e. two or more antiepileptic drugs had failed) aged between 1 and 18 years. Data were derived from literature and expert meetings. Deterministic and probabilistic sensitivity analyses were performed. Our results suggest that KD is more effective and less costly, and thus cost-effective compared with VNS, after 12 months. However, compared to CAU, neither KD nor VNS are cost-effective options, they are both more effective but also more expensive (€346,899 and €641,068 per QALY, respectively). At 5 years, VNS is cost-effective compared with KD and CAU (€11,378 and €68,489 per QALY, respectively) and has a 51% probability of being cost-effective at a ceiling ratio of €80,000 per QALY. Our results suggest that on average the benefits of KD and VNS fail to outweigh the costs of the therapies. However, these treatment options should not be ignored in the treatment for intractable epilepsy in individual or specific groups of patients. There is a great need for high quality comparative studies with large patient samples which allow for subgroup analyses, long-term follow-up periods and outcome measures that measure effects beyond seizure frequency (e.g. quality of life). When this new evidence becomes available, reassessment of the cost-effectiveness of KD and VNS in children with intractable epilepsy should be carried out. Copyright © 2014 Elsevier B.V.

    The management of middle-aged and elderly patients with catatonic schizophrenia has long been a major problem in clinical geriatric psychiatry. Most cases are intractable because of medication resistance, medication intolerance, or severe medical conditions. Electroconvulsive therapy (ECT) is recognized as one of the most efficacious therapies for catatonic schizophrenia. Thus, we conducted a prospective study of the short-term effect of acute ECT on middle-aged and elderly patients with intractable catatonic schizophrenia. Subjects were nine consecutive patients older than 45 years who had fulfilled the DSM-IV criteria for catatonic-type schizophrenia and had been referred for first-time acute ECT after other treatments had failed. The patients were treated at Tohoku University Hospital between January 1998 and March 2002. We evaluated the clinical response of these patients to acute ECT by means of the brief psychiatric rating scale (BPRS). We also evaluated adverse effects of acute ECT. The response rate was 100%. The total BPRS score was improved in all nine subjects at the end of the ECT course and 1 week after the final session in comparison with the total pre-ECT BPRS score (11.9 +/- 7.5 and 9.3 +/- 9.2 versus 57.1 +/- 13.1, respectively, p = 0.008, p = 0.008). The total Global Assessment of Functioning score was also improved significantly (from 10.8 +/- 9.4 just before ECT to 61.6 +/- 18.9 1 week after ECT, p = 0.008). Guy's five factors (thought disturbance, activation, anxiety-depression, hostility-suspiciousness, and anergia) improved significantly (p = 0.008, p = 0.008, p = 0.018, p = 0.012, p = 0.008, respectively). One patient showed supraventricular premature contractions (SVPCs) during an ECT seizure. After some ECT sessions, three patients exhibited mild to moderate delirium that disappeared within 3 days. However, no patient experienced a severe cognitive or physical adverse effect during the course of ECT. Acute ECT has a good short-term effect

  20. Reappraising neuropathic pain in humans--how symptoms help disclose mechanisms.

    Neuropathic pain--that is, pain arising directly from a lesion or disease that affects the somatosensory system--is a common clinical problem, and typically causes patients intense distress. Patients with neuropathic pain have sensory abnormalities on clinical examination and experience pain of diverse types, some spontaneous and others provoked. Spontaneous pain typically manifests as ongoing burning pain or paroxysmal electric shock-like sensations. Provoked pain includes pain induced by various stimuli or even gentle brushing (dynamic mechanical allodynia). Recent clinical and neurophysiological studies suggest that the various pain types arise through distinct pathophysiological mechanisms. Ongoing burning pain primarily reflects spontaneous hyperactivity in nociceptive-fibre pathways, originating from 'irritable' nociceptors, regenerating nerve sprouts or denervated central neurons. Paroxysmal sensations can be caused by several mechanisms; for example, electric shock-like sensations probably arise from high-frequency bursts generated in demyelinated non-nociceptive Aβ fibres. Most human and animal findings suggest that brush-evoked allodynia originates from Aβ fibres projecting onto previously sensitized nociceptive neurons in the dorsal horn, with additional contributions from plastic changes in the brainstem and thalamus. Here, we propose that the emerging mechanism-based approach to the study of neuropathic pain might aid the tailoring of therapy to the individual patient, and could be useful for drug development.
