    Thunderclap headache, a severe headache which is maximal in intensity at onset, is associated with numerous underlying disorders, including subarachnoid hemorrhage, unruptured intracranial aneurysm, cervical artery dissection, cerebral venous sinus thrombosis, stroke, intracranial hemorrhage, reversible cerebral vasoconstriction syndrome, and reversible posterior leukoencephalopathy. After exclusion of all possible causes, thunderclap headache may be considered a primary headache. This review summarizes the diagnostic considerations and clinical approach to thunderclap headache, with particular emphasis on the reversible cerebral vasoconstriction syndromes. PMID:20352589

    Optimum acute treatment of migraine requires prevention of headache as a top priority. Recognition of the multitude of migraine presentations, the frequency of total headache attacks, and number of days of headache disability are critical. Successful treatment requires excellent patient-clinician communication enhancing confidence and mutual trust based on patient needs and preferences. Optimum management of acute migraine nearly always requires pharmacologic treatment for rapid resolution. Migraine-specific triptans, dihydroergotamine, and several antiinflammatories have substantial empirical clinical efficacy. Older nonspecific drugs, particularly butalbital and opioids, contribute to medication overuse headache and are to be avoided. Clinicians should utilize evidence-based acute migraine-specific therapy stressing the imperative acute treatment goal of early intervention, but not too often with the correct drug, formulation, and dose. This therapy needs to provide cost-effective fast results, meaningful to the patient while minimizing the need for additional drugs. Migraine-ACT evaluates 2-hour pain freedom with return to normal function, comfort with treatment, and consistency of response. Employ a thoroughly educated patient, formulary, testimonials, stratification, and rational cotherapy against the race to central sensitization for optimum outcomes. PMID:20352584

    A 36-year-old man with a history of migraine headache attempted to hike from Lukla, Nepal, to Mount Everest Base Camp. On the sixth day of hiking, he had a migraine headache. After achieving resolution with typical therapies and rest, he ascended higher. Another headache developed that was interpreted to be a migraine. The headache was treated, and he ascended higher, after which severe symptoms of acute mountain sickness developed, necessitating his evacuation by helicopter. Persons with headaches in daily life may present challenges to diagnosis when traveling to high altitude. Careful evaluation and decision making are needed to achieve proper diagnosis and treatment of acute mountain sickness. PMID:24462763

    Headache is an alarm symptom, whether there is an organic disease (lesional headache) or a perturbation of one of the various functions of the head (functional headache). Lesional headaches follow a sinusitis or an arthrosis, or accompany a "temporal arteritis of Horton". Functional headaches include several varieties. 1. Trigemellar neuralgia. 2. Vascular algia originating from the basal arteries, the large cerebral venous sinuses or the branches of the external carotid. Among these are: a) headaches due to a dilatation of the internal wall, causing "Horton headache", migrain-like psychosomatic migraine and hormonal migraines (premenstrual, menstrual, menopausal or linked to the use of contraceptive pills); b) headaches caused by an angiospasm of the arteriole, which is the case in exposure to the cold, in traumatic headaches (malfunction of temporomandibular articulation, dry alveolitis), in psychosomatic angiospastic algias and in ethmoidal artery algias previously described by the author in 1949 (Godin's disease). 3. Headaches due to psychic hypertension. 4. Postconcussional psychogenic headaches. 5. Neurotic headaches. The author gives a detailed description of the subjective symptoms in each case, including localisation, form, intensity, duration course and associated phenomenons. This facilitates greatly the differential diagnosis and the choice of complementary examinations. Necessary biological investigations should be performed (e.g. hormonal balance). One should however avoid to increase the number of complementary examinations which would only delay treatment and would expose patients to somatisation. Furthermore, in each case drug treatment, periarterial infiltration technics of the temporal, internal frontal, facial, mastoid and occipital arteries are described.

    Background: Headache is a frequent symptom of many systemic diseases that do not involve cranial structures. In this observational study, we assessed factors associated with headache in the acute presentation of systemic conditions in a nonsurgical emergency department (ED). Methods: Consecutive patients, admitted to Soroka University Medical Center ED due to noncephalic illness, were prospectively surveyed using a structured questionnaire focused on the prevalence and characteristics of headache symptoms. Medical data were extracted from the patient's charts. Results: Between 1 and 6/2012, 194 patients aged 64.69 ± 19.52 years, were evaluated. Headache was reported by 83 (42.7%) patients and was more common among patients with febrile illness (77.5% vs. 22.5%, P < 0.001). Respiratory illness and level of O2 saturation were not associated with headache. Headache in the presentation of a noncephalic illness was associated with younger age (58 vs. 69, P < 0.001) and with suffering from a primary headache disorder (48.2% vs. 10.8%, P < 0.001). Headache was also associated with higher body temperature and lower platelets count. Conclusions: Headache is a common symptom in acute noncephalic conditions and was found to be associated with younger age and febrile disease on presentation. Patients who present with primary headache disorders are more prone to have headache during acute illness. Acute obstructive respiratory disease, hypercarbia or hypoxemia were not associated with headache. PMID:26752891

    2001-01-01

    Children with acute and chronic headaches are often seen by primary care providers. A complete, elaborate history, obtained from both the parents and child, is key in diagnosing and managing the child who presents with a headache. A thorough social and educational history may reveal significant school or family stresses. Historic features of concern must be explored immediately. A thorough physical examination with a focused neurologic examination must be done Focal neurologic findings may indicate serious organic problems. A comprehensive approach to the management of headaches in children consisting of reassurance, education, pharmacologic interventions, and nonpharmacologic interventions is presented. A two-tiered management plan is used in conjunction with medications. The aim of this article is to provide the novice or experienced practitioner with a comprehensive review of acute and chronic headache pathogenesis, assessment, and management. This review includes migraines and other nonmigraine types of headaches. PMID:11562640

    Purpose Headache at altitudes has had an incidence of 25-62% through many related studies. Many reasons are identified concerning headache at altitudes such as acute mountain sickness (AMS), sinus headache, migraine, tension type headache, and frontal tension headache. This study tried to compare different types of headache among trekkers on Mount Damavand, a 5671m mountain, Iran, to find their incidence and related symptoms and signs. Methods Through a cross-sectional study, we evaluated headache incidence and its correlation to AMS among people who climbed Mount Damavand. Lake Louise Score, a self-report questionnaire, was applied to make AMS diagnosis through three separate stages of trekking programs. Chi-square test was employed as the main mean of analysis. Results Totally, 459 between 13-71 year olds participated in the study among which females were 148 (32.1%) and males 311 (67.8%). Headache was found in 398 (86.7%) among whom 279 (70%) were proved as AMS. Investigating the types of headache in the cases of AMS showed 64.5% to be of steady, 31% throbbing and 4.5% stabbing characters which had significant differences with a P value = 0.003. The majority of headaches were stated as frontal (38.9%) and the least prevalence belonged to the parietal area (4.4%), while global headache was reported in 27%. Conclusions This study specifies the exact location of headaches at altitude in cases of AMS and non-AMS headaches. Many cases of high altitude non-AMS headache are resulted by tension and light reflection at altitude. PMID:22942999

    Idiopathic granulomatous hypophysitis (GH) is an uncommon inflammatory disease of the pituitary with impairment of pituitary gland function due to infiltration by lymphocytes, plasma cells and macrophages. We report the case of a 39-year-old woman who presented with worsening of headaches for 1 month and blurring of vision over 5 days. An MRI revealed a homogeneous supra-sellar mass evoking a pituitary tumour with bulky pituitary stalk extending into the left and right cavernous sinuses. Hormonal investigations showed anterior pituitary hormone deficiencies; meanwhile histopathological examination revealed an aspect of hypophysitis. Clinical and radiological remission occurred immediately postglucocorticoid therapy with the addition of a steroid-sparing agent later in view of recurrence of symptoms on glucocorticoid dose reduction. GH has important diagnostic and therapeutic implications, as clinical and radiological features ameliorate via medical treatment. With further understanding and recognition of the disease, we hope to highlight a case of GH, in which signs and symptoms improved after initiation of corticosteroids. PMID:27613264

    Sneddon's syndrome is a rare vascular disease affecting mainly skin and brain arterioles leading to their occlusion due to excessive endothelial proliferation. The two main features of this syndrome are livedo reticularis and lacunar subcortical infarcts. Here, we describe the case of a 64-year-old woman presenting with a 4-year history of a throbbing, bilateral, parieto-occipital headache associated with facial pain, but without any other accompanying symptom. The pain, initially misdiagnosed as atypical trigeminal neuralgia, worsened up to chronic daily and such severely disabling headache that she was constrained to bed. She presented with reduced cognitive functions, diffuse and severe livedo reticularis, severe myalgias and mild stiffness. All diagnostic test for different diseases were performed and other diseases excluded except for Sneddon's syndrome. Her symptoms were reduced firstly using acetylsalicylic acid, then ticlopidine 250 mg bid was begun and then Pentoxyphillin, resulting in a significant improvement of symptoms with the disappearance of headache. Her worsening in the first year was characterized by obsessive-compulsive behaviours, body-image misperceptions and panic attacks, improved for a period using olanzapine. Considering this case, we remark the importance of using headache classification to avoid diagnostic errors, secondly, we describe an atypical manifestation of Sneddon's syndrome and therapeutic efficacy of using ticlopidine and pentoxyphillin.

  19. A systematic review of causes of sudden and severe headache (Thunderclap Headache): should lists be evidence based?

    PubMed Central

    2014-01-01

    Background There are many potential causes of sudden and severe headache (thunderclap headache), the most important of which is aneurysmal subarachnoid haemorrhage. Published academic reviews report a wide range of causes. We sought to create a definitive list of causes, other than aneurysmal subarachnoid haemorrhage, using a systematic review. Methods Systematic Review of EMBASE and MEDLINE databases using pre-defined search criteria up to September 2009. We extracted data from any original research paper or case report describing a case of someone presenting with a sudden and severe headache, and summarized the published causes. Results Our search identified over 21,000 titles, of which 1224 articles were scrutinized in full. 213 articles described 2345 people with sudden and severe headache, and we identified 6 English language academic review articles. A total of 119 causes were identified, of which 46 (38%) were not mentioned in published academic review articles. Using capture-recapture analysis, we estimate that our search was 98% complete. There is only one population-based estimate of the incidence of sudden and severe headache at 43 cases per 100,000. In cohort studies, the most common causes identified were primary headaches or headaches of uncertain cause. Vasoconstriction syndromes are commonly mentioned in case reports or case series. The most common cause not mentioned in academic reviews was pneumocephalus. 70 non-English language articles were identified but these did not contain additional causes. Conclusions There are over 100 different published causes of sudden and severe headache, other than aneurysmal subarachnoid haemorrhage. We have now made a definitive list of causes for future reference which we intend to maintain. There is a need for an up to date population based description of cause of sudden and severe headache as the modern epidemiology of thunderclap headache may require updating in the light of research on cerebral

    2006-12-01

    Recent progress in the treatment of primary headaches has made available specific, effective and safe medications for these disorders, which are widely spread among the general population. One of the negative consequences of this undoubtedly positive progress is the risk of drug-drug interactions. This review is the first in a two-part series on pharmacokinetic drug-drug interactions of headache medications. Part I addresses acute treatments. Part II focuses on prophylactic treatments. The overall aim of this series is to increase the awareness of physicians, either primary care providers or specialists, regarding this topic. Pharmacokinetic drug-drug interactions of major severity involving acute medications are a minority among those reported in literature. The main drug combinations to avoid are: i) NSAIDs plus drugs with a narrow therapeutic range (i.e., digoxin, methotrexate, etc.); ii) sumatriptan, rizatriptan or zolmitriptan plus monoamine oxidase inhibitors; iii) substrates and inhibitors of CYP2D6 (i.e., chlorpromazine, metoclopramide, etc.) and -3A4 (i.e., ergot derivatives, eletriptan, etc.), as well as other substrates or inhibitors of the same CYP isoenzymes. The risk of having clinically significant pharmacokinetic drug-drug interactions seems to be limited in patients with low frequency headaches, but could be higher in chronic headache sufferers with medication overuse.

    OBJECT The relationship between headaches, pituitary adenomas, and surgical treatment of pituitary adenomas remains unclear. The authors assessed the severity and predictors of self-reported headaches in patients referred for surgery of pituitary adenomas and evaluated the impact of endoscopic transsphenoidal surgery on headache severity and quality of life (QOL). METHODS In this prospective study, 79 patients with pituitary adenomas underwent endoscopic transsphenoidal resection and completed the Headache Impact Test (HIT-6) and the 36-Item Short Form Health Survey (SF-36) QOL questionnaire preoperatively and at 6 weeks and 6 months postoperatively. RESULTS Preoperatively, 49.4% of patients had mild headache severity, 13.9% had moderate severity, 13.9% had substantial severity, and 22.8% had intense severity. Younger age and hormone-producing tumors predisposed greater headache severity, while tumor volume, suprasellar extension, chiasmal compression, and cavernous sinus invasion of the pituitary tumors did not. Preoperative headache severity was found to be significantly associated with reduced scores across all SF-36 QOL dimensions and most significantly associated with mental health. By 6 months postoperatively, headache severity was reduced in a significant proportion of patients. Of the 40 patients with headaches causing an impact on daily living (moderate, substantial, or intense headache), 70% had improvement of at least 1 category on HIT-6 by 6 months postoperatively, while headache worsened in 7.6% of patients. The best predictors of headache response to surgery included younger age, poor preoperative SF-36 mental health score, and hormone-producing microadenoma. CONCLUSIONS The results of this study confirm that surgery can significantly improve headaches in patients with pituitary adenomas by 6 months postoperatively, particularly in younger patients whose preoperative QOL is impacted. A larger multicenter study is underway to evaluate the long

    Tension-type headache is the most frequent form of headache. The local topical treatment with peppermint oil (oleum menthae piperitae) has proven to be significantly more effective than placebo in controlled studies. Peppermint oil targets headache pathophysiology in multiple ways. The efficacy is comparable to that of acetylsalicylic acid or paracetamol. Solutions of 10 % peppermint oil in ethanol are licensed for the treatment of tension-type headache in adults and children above 6 years. It is included in treatment recommendations and guidelines by the respective professional societies and is regarded as a standard treatment for the acute therapy of tension-type headaches.

    Background Dyspepsia and headache frequently co-exist, but the clinical implication of this association is uncertain. We planned to examine the prevalence and impact of dyspepsia in adults with headache. Methods A cross-sectional study was conducted in a secondary care setting. Clinical, psychological and health-related quality of life (HRQOL) data were compared between subjects with headache and controls (non-headache subjects). The impact of dyspepsia was analysed further in subjects with headache alone. Results 280 subjects (93 cases with headache and 187 matched controls) were recruited. The following baseline characteristics of subjects were as follows: mean age 45.0±17.3 years, 57.0% females and ethnic distribution—Malaysian = 45 (48.4%), Chinese n = 24 (25.8%) and Indians n = 24 (25.8%). Headache sub-types among cases with headache were as follows: tension-type headache (TTH) n = 53 (57.0%) and migraine n = 40 (43.0%). Dyspepsia was more prevalent in cases with headache compared to controls (25.8% vs 12.8%, p = 0.011), and headache was independently associated with dyspepsia (OR 2.75, 95% CI 1.39–5.43). Among cases with headache, there was a trend towards a higher prevalence of dyspepsia in those with migraine (27.5%) compared to TTH (24.5%). Subjects with headache and dyspepsia, compared to those with headache alone, had a greater severity of headache symptoms (63.67±22.85 mm vs 51.20 ±24.0 mm VAS, p = 0.029). Overall HRQOL scores were lower in headache subjects with dyspepsia (EQ-5D summary score 0.82±0.18 vs 0.90 ±0.16, p = 0.037 and EQ-5D VAS 62.08±17.50 mm vs 72.62 ±18.85 mm, p = 0.018), compared to those without dyspepsia. Conclusion Dyspepsia is associated with more severe headache symptoms and results in a lower HRQOL in patients with headache. PMID:25629323

    Study Design Retrospective study. Purpose To identify the prevalence of severe headache occurring after cervical posterior surgical fixation (PSF) and to evaluate the clinical and radiological findings associated with severe headache after surgery. Overview of Literature Several studies have reported on the axial pain after cervical surgery. However, to our knowledge, the incidence of severe headache after cervical PSF has not been elucidated. Methods The medical records and radiological assessment of patients who underwent surgical treatment from August 2002 to May 2012 were reviewed to identify the prevalence and risk factors for severe headaches occurring following PSF from C2 distally. Neck disability index scores (NDI) (the item for neck pain), the type of C2 screw, number of cervical fused levels (1–6), and smoking habit were calculated preoperatively and postoperatively. In addition, radiological parameters (T1 slope angle, C1/2 angle, C2–7 Cobb angle, C2–7 sagittal vertical axis and C1-implant distance) were assessed for all patients. Severe headache was defined as a high NDI headache score (>4 out of 5). Results Eighty-two patients met the inclusion criteria. The mean age was 59.2 years (range, 21–78 years), and the mean number of fused levels was 5.1. The mean follow-up period was 2.9 years (range, 1–10.9 years). While only one severe headache occurred de novo postoperatively in a patient in the C3 or C4 distally group (total 30 patients, average age of 50.2 years), 11 patients in the C2 distally group (p=0.04) had severe headache occur postoperatively. The radiological parameters were not significantly different between the postoperative milder headache and severe headache (SH) groups. The SH group had a significantly higher preoperative NDI score (neck pain) (p<0.01). Conclusions Newly occurring severe headaches can occur in 18% of patients after PSF from C2 distally. The patients with newly occurring severe headaches had significantly higher

    Background Despite the impact of sodium valproate and dexamethasone on migraine headache, the efficacy of the two drugs has not been properly investigated and compared. This trial compared the effect of the two drugs on acute migraine headache. Methods This double blind randomized clinical trial was conducted on patients aged 18 to 65 years with acute migraine headache who referred to the emergency departments of Beasat and Farshchian Hospitals in Hamadan, Iran, from April 2012 to June 2014. Patients were randomly assigned to receive a single-dose of either 400 mg sodium valproate or 16 mg dexamethasone plus 50 ml saline normal solution within 15 min intravenously. The severity of headache in the two groups was evaluated at baseline, 0.5 and 2 hours later using the Visual Analog Scale (VAS) on a scale of 0 to 10. Results Of 104 patients enrolled, 72 patients remained for analysis. The effect of both sodium valproate and dexamethasone on acute migraine headache was statistically significant at 0.5 and 2 hours post-treatment compared to pre-treatment (P=0.001). The severity of headache based on VAS reduced form 8.20 (7.72, 8.68) before treatment to 5.31 (4.74, 5.89) and 3.66 (2.99, 4.33) at 0.5 and 2 hours after treatment, respectively, in patients receiving sodium valproate and from 8.46 (8.05, 8.86) before treatment to 5.46 (4.81, 6.11) and 3.59 (2.84, 4.35) at 0.5 and 2 hours after treatment, respectively, in patients receiving dexamethasone. Both drugs were highly effective in improvement of acute headache in patients without aura. However, sodium valproate significantly improved the acute headache in patients with aura but dexamethasone did not. The severity of headache based on VAS reduced form 8.50 (7.40, 9.60) before treatment to 4.67 (2.40, 6.93) and 3.50 (1.78, 5.22) at 0.5 and 2 hours after treatment, respectively, in patients with aura receiving sodium valproate and from 8.80 (7.76, 9.84) before treatment to 7.20 (4.98, 9.42) and 6.20 (2.43, 9.97) at 0

    Background Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter analgesics. Co-therapy with an antiemetic should help to reduce nausea and vomiting commonly associated with migraine headaches. Objectives To determine the efficacy and tolerability of aspirin, alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine headaches in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies through 10 March 2010. Selection criteria We included randomised, double-blind, placebo- or active-controlled studies using aspirin to treat a discrete migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and numbers needed to treat (NNT) or harm (NNH) compared to placebo or other active treatment. Main results Thirteen studies (4222 participants) compared aspirin 900 mg or 1000 mg, alone or in combination with metoclopramide 10 mg, with placebo or other active comparators, mainly sumatriptan 50 mg or 100 mg. For all efficacy outcomes, all active treatments were superior to placebo, with NNTs of 8.1, 4.9 and 6.6 for 2-hour pain-free, 2-hour headache relief, and 24-hour headache relief with aspirin alone versus placebo, and 8.8, 3.3 and 6.2 with aspirin plus metoclopramide versus placebo. Sumatriptan 50 mg did not differ from aspirin alone for 2-hour pain-free and headache relief, while sumatriptan 100 mg was better than the combination of aspirin plus metoclopramide for 2-hour pain-free, but not headache relief; there were no data for 24-hour headache relief.

    Headache is the most common complaint encountered in clinical practice. Approximately 45 million people in the United States experience chronic headaches. The management of migraine headache involves both pharmacologic and nondrug therapy. Drug therapy for migraine involves the use of abortive and prophylactic agents. Abortive agents, such as ergotamine tartrate and ketoprofen, may be used to relieve the acute attack. Prophylactic therapy is focused on reducing the frequency and severity of the attacks. beta-Adrenergic blocking agents, such as propranolol, remain the primary agents for many migraine patients, although other drugs, such as nonsteroidal anti-inflammatory drugs (NSAIDs), including ketoprofen, or calcium-channel blocking agents, such as verapamil, may be beneficial for many patients. For cluster headache and its variants, methysergide and corticosteroids are usually the drugs of choice. Patients with chronic cluster headache may achieve good results from long-term treatment with other therapies, including lithium carbonate, verapamil, and ketoprofen. PMID:2520442

    A group of 129 subjects (67 men and 62 women) experiencing sports headache was established using a questionnaire. A wide range of information was gathered, focusing on the mode of onset, time course, characteristic features and associated symptoms of sports-related headache. Criteria for the varieties of sports headaches were established using head trauma and then migraine to divide subgroups of sports headaches. Cases were classified into four categories: effort migraine, trauma-triggered migraine, effort-exertion headache, and post-traumatic headache. The percentages of each sports-related headache found were: effort migraine 9%, trauma-triggered migraine 6%, effort-exertion headache 60%, post-traumatic headache 22% and miscellaneous 3%. Sports migraine accounted for 15% of the total sports headache sample. Effort-exertion headache was the most common type of sports headache. Although effort-exertion headache could be separated into subjects who had an acute severe headache induced by anaerobic exercise (exertion headache) from those having a substantial headache lasting hours initiated by aerobic exercise (effort headache), most subjects with effort-exertion headache in this study appeared not to fall into any discrete subgroups. Trauma-related headaches were experienced mainly by men in contact sports, while women more commonly had non-trauma-related headache in running and jogging. PMID:7921916

    Background Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter analgesics. Co-therapy with an antiemetic should help to reduce nausea and vomiting commonly associated with migraine. Objectives To determine the efficacy and tolerability of paracetamol (acetaminophen), alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies through 4 October 2010. Selection criteria We included randomised, double-blind, placebo- or active-controlled studies using self-administered paracetamol to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and numbers needed to treat (NNT) or harm (NNH) compared to placebo or other active treatment. Main results Ten studies (2769 participants, 4062 attacks) compared paracetamol 1000 mg, alone or in combination with an antiemetic, with placebo or other active comparators, mainly sumatriptan 100 mg. For all efficacy outcomes paracetamol was superior to placebo, with NNTs of 12, 5.2 and 5.0 for 2-hour pain-free and 1- and 2-hour headache relief, respectively, when medication was taken for moderate to severe pain. Nausea, photophobia and phonophobia were reduced more with paracetamol than with placebo at 2 hours (NNTs of 7 to 11); more individuals were free of any functional disability at 2 hours with paracetamol (NNT 10); and fewer participants needed rescue medication over 6 hours (NNT 6). Paracetamol 1000 mg plus metoclopramide 10 mg was not significantly different from oral sumatriptan

    The prevalence of cluster headache is 0.1% and cluster headache is often not diagnosed or misdiagnosed as migraine or sinusitis. In cluster headache there is often a considerable diagnostic delay - an average of 7 years in a population-based survey. Cluster headache is characterized by very severe or severe orbital or periorbital pain with a duration of 15-180 minutes. The cluster headache attacks are accompanied by characteristic associated unilateral symptoms such as tearing, nasal congestion and/or rhinorrhoea, eyelid oedema, miosis and/or ptosis. In addition, there is a sense of restlessness and agitation. Patients may have up to eight attacks per day. Episodic cluster headache (ECH) occurs in clusters of weeks to months duration, whereas chronic cluster headache (CCH) attacks occur for more than 1 year without remissions. Management of cluster headache is divided into acute attack treatment and prophylactic treatment. In ECH and CCH the attacks can be treated with oxygen (12 L/min) or subcutaneous sumatriptan 6 mg. For both oxygen and sumatriptan there are two randomized, placebo-controlled trials demonstrating efficacy. In both ECH and CCH, verapamil is the prophylactic drug of choice. Verapamil 360 mg/day was found to be superior to placebo in one clinical trial. In clinical practice, daily doses of 480-720 mg are mostly used. Thus, the dose of verapamil used in cluster headache treatment may be double the dose used in cardiology, and with the higher doses the PR interval should be checked with an ECG. At the start of a cluster, transitional preventive treatment such as corticosteroids or greater occipital nerve blockade can be given. In CCH and in long-standing clusters of ECH, lithium, methysergide, topiramate, valproic acid and ergotamine tartrate can be used as add-on prophylactic treatment. In drug-resistant CCH, neuromodulation with either occipital nerve stimulation or deep brain stimulation of the hypothalamus is an alternative treatment strategy

Main results Nine studies (4373 participants, 5223 attacks) compared ibuprofen with placebo or other active comparators; none combined ibuprofen with a self-administered antiemetic. All studies treated attacks with single doses of medication. For ibuprofen 400 mg versus placebo, NNTs for 2-hour pain-free (26% versus 12% with placebo), 2-hour headache relief (57% versus 25%) and 24-hour sustained headache relief (45% versus 19%) were 7.2, 3.2 and 4.0, respectively. For ibuprofen 200 mg versus placebo, NNTs for 2-hour pain-free (20% versus 10%) and 2-hour headache relief (52% versus 37%) were 9.7 and 6.3, respectively. The higher dose was significantly better for 2-hour headache relief than the lower dose. Soluble formulations of ibuprofen 400 mg were better than standard tablets for 1-hour, but not 2-hour headache relief

    Severe acute pancreatitis (SAP) develops in about 25% of patients with acute pancreatitis. Severity of acute pancreatitis is linked to the presence of systemic organ dysfunctions and/or necrotizing pancreatitis. Risk factors independently determining the outcome of SAP are early multiorgan failure (MOF), infection of necrosis, and extended necrosis (>50%). Morbidity of SAP is biphasic, in the first week it is strongly related to systemic inflammatory response syndrome while, sepsis due to infected pancreatic necrosis leading to MOF syndrome occurs in the later course after the first week. Contrast-enhanced computed tomography provides the highest diagnostic accuracy for necrotizing pancreatitis when performed after the first week of disease. Patients who suffer early organ dysfunctions or are at risk for developing a severe disease require early intensive care treatment. Antibiotic prophylaxis has not been shown as an effective preventive treatment. Early enteral feeding is based on a high level of evidence, resulting in a reduction of local and systemic infection. Patients suffering infected necrosis causing clinical sepsis are candidates for intervention. Hospital mortality of SAP after interventional or surgical debridement has decreased to below 20% in high-volume centers. PMID:23372306

    Headaches are one of the most common disorders and symptoms in daily medical practice. There has been dramatic progress of knowledge in the fields of epidemiology, pathophysiology, acute treatment, and preventive therapy over the past 100 years. Triptans have been the breakthrough in the treatment of acute migraine attacks. Beta blockers, calcium antagonists, and neuromodulators are available for preventive migraine therapy. Treatment for chronic tension headache is still unsatisfying. Cluster headache is part of the group of trigemino-autonomic headaches. Headache from medication overuse plays an increasingly important role. New medical care structures such as integrated headache care provide better support for patients with chronic headache disorders. PMID:17687534

    Severe acute malnutrition (SAM) is associated with increased severity of common infectious diseases, and death amongst children with SAM is almost always as a result of infection. The diagnosis and management of infection are often different in malnourished versus well-nourished children. The objectives of this brief are to outline the evidence underpinning important practical questions relating to the management of infectious diseases in children with SAM and to highlight research gaps. Overall, the evidence base for many aspects covered in this brief is very poor. The brief addresses antimicrobials; antipyretics; tuberculosis; HIV; malaria; pneumonia; diarrhoea; sepsis; measles; urinary tract infection; nosocomial Infections; soil transmitted helminths; skin infections and pharmacology in the context of SAM.

    The increasing popularity of scuba diving has added a new category to the differential diagnosis of headache. Headache in divers, while uncommon and generally benign, can occasionally signify serious consequences of hyperbaric exposure such as arterial gas embolism, decompression sickness, and otic or paranasal sinus barotrauma. Inadequate ventilation of compressed gases can lead to carbon dioxide accumulation, cerebral vasodilatation, and headache. Other types of headache encountered in divers include exertional headache, cold stimulus headache, migraine, tension-type headache, acute traumatic headache, cervicogenic headache, carbon monoxide poisoning headache, and headache associated with envenomation. Correct diagnosis and appropriate treatment require a careful history and neurologic examination as well as an understanding of the unique physiologic stresses of the subaquatic environment.

She was initially diagnosed with ruptured ectopic pregnancy and ruptured corpus luteal cyst as the differential diagnosis. However she then, was finally diagnosed as acute hemorrhagic pancreatitis with spontaneous complete miscarriage. This is followed by review of literature on this topic. Acute pancreatitis in pregnancy is not uncommon. The emphasis on high index of suspicion of acute pancreatitis in women who presented with acute abdomen in pregnancy is highlighted.

    Irrespective of diagnosis, chronic daily, morning, or "awakening" headache patterns are soft signs of a sleep disorder. Sleep apnea headache may emerge de novo or may present as an exacerbation of cluster, migraine, tension-type, or other headache. Insomnia is the most prevalent sleep disorder in chronic migraine and tension-type headache, and increases risk for depression and anxiety. Sleep disturbance (e.g., sleep loss, oversleeping, schedule shift) is an acute headache trigger for migraine and tension-type headache. Snoring and sleep disturbance are independent risk factors for progression from episodic to chronic headache. PMID:23099138

    Severe acute respiratory syndrome (SARS) is a viral disease, observed primarily in Southern China in November 2002, with variable flu-like symptoms and pneumonia, in approx. 5% leading to death from respiratory distress syndrome (RDS). The disease was spread over more than 30 states all over the globe by SARS-virus-infected travelers. WHO and CDC received first information about a new syndrome by the end of February 2003, after the first cases outside the Republic of China had been observed. A case in Hanoi, Vietnam, led to the first precise information about the new disease entity to WHO, by Dr. Carlo Urbani, a co-worker of WHO/Doctors without Borders, who had been called by local colleagues to assist in the management of a patient with an unknown severe disease by the end of February 2003. Dr. Urbani died from SARS, as did many other health care workers. In the meantime, more than 7,000 cases have been observed worldwide, predominantly in China and Hong Kong, but also in Taiwan, Canada, Singapore, and the USA, and many other countries, and more than 600 of these patients died from RDS. Since the beginning of March 2003, when WHO and CDC started their activities, in close collaboration with a group of international experts, including the Bernhard-Nocht-Institute in Hamburg and the Department of Virology in Frankfurt/Main, a previously impossible success in the disclosure of the disease was achieved. Within only 8 weeks of research it was possible to describe the infectious agent, a genetically modified coronavirus, including the genetic sequence, to establish specific diagnostic PCR methods and to find possible mechanisms for promising therapeutic approaches. In addition, intensifying classical quarantine and hospital hygiene measures, it was possible to limit SARS in many countries to sporadic cases, and to reduce the disease in countries such as Canada and Vietnam.

    Exercise-related headache is one of the most common medical problems affecting the modern-day athlete. Despite the high prevalence of headache in community populations, the epidemiology of sports-related headache is unclear. In certain collision sports, up to 50% of athletes report regular headaches as a consequence of their athletic participation. The classification of the different types of sport-related headache by the International Headache Society (IHS) and in previously published articles does not adequately encompass the clinical problem faced by team physicians. Confusion exists where terms such as 'effort headache' and 'exertional headache' may be used to describe similar entities. In this review, the specific headache entities discussed include benign exertional headache, effort headache, acute post-traumatic headache and cervicogenic headache. For the sports physician, an understanding of the variety of specific headache syndromes that occur with particular sports is necessary for everyday clinical practice. This article reviews the common exercise-related headache syndromes and attempts to provide a framework for their overall management. Team physicians also need to be cognisant that many of the standard preparations used to treat headaches may be banned drugs under International Olympic Committee (IOC) rules. PMID:10999425

    The study aims to provide an updated assessment of the evidence for individual pharmacological therapies for acute migraine treatment. Pharmacological therapy is frequently required for acutely treating migraine attacks. The American Academy of Neurology Guidelines published in 2000 summarized the available evidence relating to the efficacy of acute migraine medications. This review, conducted by the members of the Guidelines Section of the American Headache Society, is an updated assessment of evidence for the migraine acute medications. A standardized literature search was performed to identify articles related to acute migraine treatment that were published between 1998 and 2013. The American Academy of Neurology Guidelines Development procedures were followed. Two authors reviewed each abstract resulting from the search and determined whether the full manuscript qualified for review. Two reviewers studied each qualifying full manuscript for its level of evidence. Level A evidence requires at least 2 Class I studies, and Level B evidence requires 1 Class I or 2 Class II studies. The specific medications - triptans (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan [oral, nasal spray, injectable, transcutaneous patch], zolmitriptan [oral and nasal spray]) and dihydroergotamine (nasal spray, inhaler) are effective (Level A). Ergotamine and other forms of dihydroergotamine are probably effective (Level B). Effective nonspecific medications include acetaminophen, nonsteroidal anti-inflammatory drugs (aspirin, diclofenac, ibuprofen, and naproxen), opioids (butorphanol nasal spray), sumatriptan/naproxen, and the combination of acetaminophen/aspirin/caffeine (Level A). Ketoprofen, intravenous and intramuscular ketorolac, flurbiprofen, intravenous magnesium (in migraine with aura), and the combination of isometheptene compounds, codeine/acetaminophen and tramadol/acetaminophen are probably effective (Level B).

    Background. Tinnitus and headache are frequent disorders. Here, we aimed to investigate whether the occurrence of headache among tinnitus patients is purely coincidental or whether tinnitus and headache are pathophysiologically linked. We investigated a large sample of patients with tinnitus and headache to estimate prevalence rates of different headache forms, to determine the relationship between tinnitus laterality and headache laterality, and to explore the relationship between tinnitus and headache over time. Method. Patients who presented at a tertiary referral center because of tinnitus and reported comorbid headache were asked to complete validated questionnaires to determine the prevalence of migraine and tension-type headache and to assess tinnitus severity. In addition, several questions about the relationship between headache and tinnitus were asked. Results. Datasets of 193 patients with tinnitus and headache were analysed. 44.6% suffered from migraine, 13% from tension-type headache, and 5.7% from both. Headache laterality was significantly related to tinnitus laterality and in the majority of patients fluctuations in symptom severity of tinnitus and headache were interrelated. Conclusion. These findings suggest a significant relationship between tinnitus and headache laterality and symptom interaction over time and argue against a purely coincidental cooccurrence of tinnitus and headache. Both disorders may be linked by common pathophysiological mechanisms. PMID:26583133

Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter (OTC) analgesics. Diclofenac is an established analgesic, and new formulations using the potassium or epolamine salts, which can be dissolved in water, have been developed for rapid absorption, which may be beneficial in acute migraine. Co-therapy with an antiemetic should help to reduce the nausea and vomiting commonly associated with migraine. Objectives To determine the efficacy and tolerability of diclofenac, alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine headaches in adults. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Oxford Pain Relief Database, ClinicalTrials.gov, and reference lists for studies through 27 September 2011. Selection criteria We included randomised, double-blind, placebo- and/or active-controlled studies using self administered diclofenac to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. We used numbers of participants achieving each outcome to calculate relative risk (or ‘risk ratio’) and numbers needed to treat to benefit (NNT) or harm (NNH) compared to placebo or a different active treatment. Main results Five studies (1356 participants) compared oral diclofenac with placebo, and one also compared it with sumatriptan; none combined diclofenac with a self administered antiemetic. Four studies treated attacks with single doses of medication, and two allowed an optional second dose for inadequate response.

    The relationship between sleep and primary headaches has been known for over a century, particularly for headaches occurring during the night or early morning. Migraine, tension-tyre headache, and cluster headache may cause sleep fragmentation, insomnia, and hypersomnia, causing considerable social and economical costs and several familial problems. By contrast, sleep disorders may themselves trigger headache attacks. Finally, headaches and sleep disorders can also be symptoms of other underlying pathologies. Despite this background, there is still no clarity about the mechanism that links these two entities and their interdependence remains to be defined. Patients with primary headache should undergo a careful assessment of sleep habits. PMID:21533713

    Objective/Background The role of diet in migraine is not well understood. We sought to characterize usual dietary intake patterns and diet quality in a nationally representative sample of women with and without severe headache or migraine. We also examined whether the relationship between migraine and diet differs by weight status. Methods In this analysis, women with migraine or severe headache status was determined by questionnaire for 3069 women, ages 20-50 years, who participated in the National Health and Nutrition Examination Study, 1999-2004. Women who experienced severe headaches or migraines were classified as migraine for the purposes of this analysis. Dietary intake patterns (micro- and macronutrient intake and eating frequency) and diet quality, measured by the Healthy Eating Index, 2005, were determined using one 24-hour dietary recall. Results Dietary intake patterns did not significantly differ between women with and without migraine. Normal weight women with migraine had significantly lower diet quality (Healthy Eating Index, 2005 total scores) than women without migraine (52.5 ± 0.9 vs 45.9 ± 1.0; P < .0001). Conclusions Whereas findings suggest no differences in dietary intake patterns among women with and without migraine, dietary quality differs by migraine status in normal weight women. Prospective analyses are needed to establish how diet relates to migraine onset, characteristics, and clinical features in individuals of varying weight status. PMID:25758250

    In the management of acute severe asthma it is very important to start the treatment as soon as possible, by appropriate evaluation of the physical status and signs of airflow obstruction. We propose a guideline to be used by patients with asthma, emergency car crews, physicians and nurses to evaluate the severity and to choose the appropriate management of acute asthma, including intubation and mechanical ventilation, by the assessment of clinical features, as well as blood gas analysis and pulmonary function test. Several researchers have demonstrated that the additional administration of aminophylline to inhaled or subcutaneous beta 2-agonist bronchodilator during the first 4 hours of an attack provides no additional benefit compared to the administration of beta 2-agonist alone. In our retrospective study of 68 episodes of acute severe asthma in the last 5 years at our institute, however, the additional administration of aminophylline with beta 2-agonists was clearly shown to be effective with infrequent minor side effects.

    The association between stroke and headache is complex, ranging from highly nonspecific, wherein headache is largely irrelevant to diagnosis and therapeutic management, to highly specific and even causative. In short, acute headache may accompany the acute stroke process, chronically complicate stroke, or, in rare instances, serve as the primary cause of stroke. With the first instance, the incidence of acute headache is highly dependent on the stroke sub-type and etiology. In this article, the headaches accompanying or causing acute stroke are addressed in some detail. PMID:15062526

    We report a case of postdural puncture headache (PDPH) after outpatient hysteroscopy under spinal anesthesia in which a 25-gauge Whitacre needle was used. Symptoms of PDPH appeared 6 hours after surgery. The headache improved with oral caffein and intravenous corticosteroids and the patient was discharged after 24 hours. Later, she was attended twice in the emergency departments of 2 hospitals, where she received conventional treatment (analgesics and corticosteroids). Eleven days after the surgical procedure, an epidural blood patch was performed. Within 12 hours the incapacitating symptoms had improved markedly and resolution was complete 2 months after surgery. PDPH worthy of blood patch treatment is a rare complication of spinal anesthesia with pencil-point needles. Clear diagnostic protocols are required if satisfactory treatment is not to be delayed and unnecessary suffering is to be prevented. PMID:20499802

    High-altitude headache is one of many neurological symptoms associated with the ascent to high altitudes. Cellular hypoxia due to decreased barometric pressure seems to be the common final pathway for headache as altitude increases. Susceptibility to high-altitude headache depends on genetic factors, history of migraine, and acclimatization, but symptoms of acute mountain sickness are universal at very high altitudes. This review summarizes the pathophysiology of acute mountain sickness and high-altitude headache as well as the evidence for treatment and prevention with different drugs and devices which may be useful for regular and novice mountaineers. This includes an examination of other headache disorders which may mimic high-altitude headache. PMID:25795155

    Pazopanib is an oral angiogenesis inhibitor targeting vascular endothelial growth factor receptors, platelet-derived growth factor receptors, and c-Kit approved for the treatment of renal cell carcinoma and soft tissue sarcoma. Nonselective kinase inhibitors, such as sunitinib and sorafenib, are known to be associated with acute pancreatitis. There are few case reports of severe acute pancreatitis induced by pazopanib treatment. We present a case of severe acute pancreatitis caused by pazopanib treatment for cutaneous angiosarcoma. The patient was an 82-year-old female diagnosed with cutaneous angiosarcoma. She had been refractory to docetaxel treatment and began pazopanib therapy. Three months after pazopanib treatment, CT imaging of the abdomen showed the swelling of the pancreas and surrounding soft tissue inflammation without abdominal pain. After she continued pazopanib treatment for 2 months, she presented with nausea and appetite loss. Abdominal CT showed the worsening of the surrounding soft tissue inflammation of the pancreas. Serum amylase and lipase levels were 296 and 177 IU/l, respectively. She was diagnosed with acute pancreatitis induced by pazopanib treatment and was managed conservatively with discontinuation of pazopanib, but the symptoms did not improve. Subsequently, an abdominal CT scan demonstrated the appearance of a pancreatic pseudocyst. She underwent endoscopic ultrasound-guided pseudocyst drainage using a flared-end fully covered self-expandable metallic stent. Then, the symptoms resolved without recurrence. Due to the remarkable progress of molecular targeted therapy, the oncologist should know that acute pancreatitis was recognized as a potential adverse event of pazopanib treatment and could proceed to severe acute pancreatitis.

Headache is the most common presenting symptom for patients presenting to A&E departments. CPD/Clinical Relevance: Most of the dental team take for granted their knowledge and ability to manage acute dental pain. However, the education and preparation in managing patients with headache conditions remains poor. Dentists are in a privileged position to be able to advise their patients about common conditions including headaches. PMID:27529913

    Headache patterns in women change in relation to fluctuations in oestrogen levels. Increasing oestrogen levels in early pregnancy offer a protective effect against headache, particularly for women with migraine. However, some women continue to experience troublesome headache throughout pregnancy. Headache persisting at the end of the first trimester will usually continue without improvement for the remainder of pregnancy and should be treated. Safe and effective acute care treatment options include paracetamol, opioids and anti-emetics. The use of triptans during pregnancy is controversial and not broadly recommended. Safe and effective preventive treatments include relaxation, biofeedback, beta-blockers, some antidepressants and gabapentin in early pregnancy. PMID:11934341

    Acute severe asthma, formerly known as status asthmaticus, is defined as severe asthma unresponsive to repeated courses of beta-agonist therapy such as inhaled albuterol, levalbuterol, or subcutaneous epinephrine. It is a medical emergency that requires immediate recognition and treatment. Oral or parenteral corticosteroids should be administered to all patients with acute severe asthma as early as possible because clinical benefits may not occur for a minimum of 6-12 hours. Approximately 50% of episodes are attributable to upper respiratory infections, and other causes include medical nonadherence, nonsteroidal anti-inflammatory exposure in aspirin-allergic patients, allergen exposure (especially pets) in severely atopic individuals, irritant inhalation (smoke, paint, etc.), exercise, and insufficient use of inhaled or oral corticosteroids. The patient history should be focused on acute severe asthma including current use of oral or inhaled corticosteroids, number of hospitalizations, emergency room visits, intensive-care unit admissions and intubations, the frequency of albuterol use, the presence of nighttime symptoms, exercise intolerance, current medications or illicit drug use, exposure to allergens, and other significant medical conditions. Severe airflow obstruction may be predicted by accessory muscle use, pulsus paradoxus, refusal to recline below 30°, a pulse >120 beats/min, and decreased breath sounds. Physicians' subjective assessments of airway obstruction are often inaccurate. More objective measures of airway obstruction via peak flow (or forced expiratory volume in 1 second) and pulse oximetry before oxygen administration usually are helpful. Pulse oximetry values >90% are less commonly associated with problems although CO(2) retention and a low Pao(2) may be missed. PMID:22794687

    Primary headache disorders such as migraine, tension-type headache, and cluster headache are prevalent and disabling neurological disorders. Although most headache disorders are largely treatable, they are under-recognized, under-diagnosed, and under-treated. Many headache sufferers in Japan do not receive appropriate and effective health care; hence, the illness, which should be relieved, persists and acts as an individual and societal burden. One of the barriers most responsible for this is poor awareness of the disorders. For lifting the burden, health care must be improved. Education is an essential way to resolve these issues at multiple levels. We have a Japanese version of the international headache classification and diagnostic criteria II (ICHD-II) and guidelines for the management of chronic headaches. Utilization of these resources is key for the improvement of headache management in our country. Not only neurologists, but also neurosurgeons and other medical specialists are participating in headache care in Japan. The Japanese Headache Society and the Japanese Society for Neurology should play major roles in health care service, education programs, as well as clinical and basic research for headache disorders. The road map for realizing our aim on headache treatment is as follows: (1) increase the number of units concerning headache in lectures for medical students, implement training programs for residents and neurologists, and offer continuous medical educations for physicians and neurologists; (2) secure more funding for headache research; (3) propagate medical care for headache in primary care settings and regional fundamental hospitals; (4) reform the health care system for headache and incentivize appropriate compensation for headache care in public health insurance; and (5) spread appropriate information on medical and socio-ethical issues related to headache for the sufferers and citizens.

    Children and adolescents with sickle cell disease (SCD) have a high prevalence of recurrent headaches (24.0-43.9 %). Acute presentation with headache can be diagnostically challenging, as the clinician must consider evaluation of several potentially devastating conditions including vascular diseases (stroke, hemorrhage, venous sinus thrombosis, moyamoya, posterior reversible encephalopathy syndrome), facial and orbital bone infarcts, dental pain, and osteomyelitis. Patients with SCD and primary headache disorders may benefit from comprehensive headache treatment plans that include abortive therapy, prophylactic therapy, and non-pharmacological modalities. Although there is limited data in adults, those with SCD are at risk for medication overuse headache secondary to frequent opioid use. Addressing headache in patients with SCD may help to reduce their use of opioids and disability and improve pain and quality of life. PMID:26879878

    Headache is a common complaint in children. Although in most cases it does not require medical attention, a thorough evaluation is mandatory for the child with severe, recurring, or unconventional headaches. Recurrent episodes of headache over a prolonged period with normal behaviour, intellectual function, and a negative physical examination suggest migraine or psychogenic headaches. Headache in a child may be indicative of a systemic illness or an intracranial process causing increased intracranial pressure. This review discusses the three most common types of headache in children, highlighting the characteristic symptoms, investigation, and management of migraine, organic, and psychogenic headaches.

    Severe acute pancreatitis (SAP) develops in about 25% of patients with acute pancreatitis (AP). Severity of AP is linked to the presence of systemic organ dysfunctions and/or necrotizing pancreatitis pathomorphologically. Risk factors determining independently the outcome of SAP are early multi-organ failure, infection of necrosis and extended necrosis (> 50%). Up to one third of patients with necrotizing pancreatitis develop in the late course infection of necroses. Morbidity of SAP is biphasic, in the first week strongly related to early and persistence of organ or multi-organ dysfunction. Clinical sepsis caused by infected necrosis leading to multi-organ failure syndrome (MOFS) occurs in the later course after the first week. To predict sepsis, MOFS or deaths in the first 48-72 h, the highest predictive accuracy has been objectified for procalcitonin and IL-8; the Sepsis-Related Organ Failure Assessment (SOFA)-score predicts the outcome in the first 48 h, and provides a daily assessment of treatment response with a high positive predictive value. Contrast-enhanced CT provides the highest diagnostic accuracy for necrotizing pancreatitis when performed after the first week of disease. Patients who suffer early organ dysfunctions or at risk of developing a severe disease require early intensive care treatment. Early vigorous intravenous fluid replacement is of foremost importance. The goal is to decrease the hematocrit or restore normal cardiocirculatory functions. Antibiotic prophylaxis has not been shown as an effective preventive treatment. Early enteral feeding is based on a high level of evidence, resulting in a reduction of local and systemic infection. Patients suffering infected necrosis causing clinical sepsis, pancreatic abscess or surgical acute abdomen are candidates for early intervention. Hospital mortality of SAP after interventional or surgical debridement has decreased in high volume centers to below 20%. PMID:17876868

  1. Looking at "thunderclap headache" differently? Circa 2016.

    PubMed

    Ravishankar, K

    2016-01-01

    The term "thunderclap headache" (TCH) was first coined in 1986 by Day and Raskin to describe headache that was the presenting feature of an underlying unruptured cerebral aneurysm. The term is now well established to describe the abrupt onset headache seen with many other conditions and is also now included in The International Classification of Headache Disorders 3(rd) edition beta version rubric 4.4. An essential to label an acute headache as "TCH" and differentiate it from other "sudden onset, severe headaches" is the arbitrary time frame of 1 min from onset to peak intensity for "TCH." What happens in practice, however, is that even those "sudden onset, severe headaches" that do not strictly fulfill the definition criteria are also labeled as "TCH" and investigated with the same speed and in the same sequence and managed based on the underlying cause. This article begins by questioning the validity and usefulness of this "one minute" arbitrary time frame to define "TCH," particularly since this time frame is very difficult to assess in practice and is usually done on a presumptive subjective basis. The article concludes with suggestions for modification of the current investigation protocol for this emergency headache scenario. This proposal for "a change in practice methodology" is essentially based on (1) the fact that in the last two decades, we now have evidence for many more entities other than just subarachnoid hemorrhage that can present as "TCH" or "sudden onset, severe headache" and (2) the evidence from literature which shows that advances in imaging technology using higher magnet strength, better contrast, and newer acquisition sequences will result in a better diagnostic yield. It is therefore time now, in our opinion, to discard current theoretical time frames, use self-explanatory terminologies with practical implications, and move from "lumbar puncture (LP) first" to "LP last!"

    Acute pancreatitis is a potentially fatal disease, the severity of which ranges from a mild edematous form to a severe necrotizing form. Most patients develop systemic inflammatory response syndrome (SIRS), which is induced by proinflammatory cytokines. The cytokine production can be induced by activation of Toll-like receptor. The breakdown products of the pancreatic and peripancreatic tissues by proteases might be the agonists. Cytokines are supposed to be produced as a biological defense system. However, cytokines may often evoke organ failure and/or immunosuppressive state, if they would be produced excessively. To express this complicated pathologic condition, Ogawa proposed a concept of LISIS(local inflammation-induced systemic immunosuppression syndrome). We have to pay attention to such aspects in the management of this disease. PMID:15552899

    Acute pancreatitis (AP) has a fast onset and progression, which lead to an unfavorable prognosis. Therefore, the development of novel drugs for its treatment is critical. As a homologous derivative of resveratrol, pterostilbene exerts a variety of effects including anti-inflammatory, antioxidant, and antitumor effects. This study investigated the potential of pterostilbene for treatment of severe AP (SAP) and related mechanisms. Effects of pterostilbene were evaluated in a Wistar rat model of AP. Serum levels of amylase (AMY), creatinine (Cr), and alanine aminotransferase (ALT) were quantified. Furthermore, serum levels of tumor necrosis factor (TNF)-a and interleukin (IL)-1b were quantified using enzyme-linked immunosorbent assay. Nuclear factor (NF)-kB expression in pancreatic tissues was quantified by real-time PCR and western blotting. The production of reactive oxygen species (ROS) was determined using a spectrometer, while superoxide dismutase (SOD) activity was assayed. In the AP rat model, the expression of inflammatory markers TNF-a and IL-1b, expression of NF-kB, and serum indices (AMY, Cr, and ALT) increased compared to the corresponding levels in the control group (P < 0.05). Pterostilbene reduced serum levels of TNF-a and IL-1b; decreased NF-kB gene expression, serum indices, and ROS generation; and increased SOD activity in a dose-dependent manner. In conclusion, pterostilbene can alleviate SAP-induced tissue damage by decreasing the inflammatory response and by promoting antioxidation leading to the protection of pancreatic tissues.

    The scientific basis of tension- type headache suffers from the lack of precise pathophysiological knowledge and the heterogenecity of this disorder. Treatment of acute tension-type headache episodes is more effective with an NSAIDs (ibuprofen 400-800mg, naproxen 550-825mg, ketoprofen 50-75mg) than with aspirin or paracetamol. Caffein containing preparations of NSAIDs are slightly superior, but should not be taken frequently to avoid headache chronification. For chronic tension-type headache, relaxation therapies with EMG biofeedback and tricyclics have about the same efficacy rate of 40-50p.100. Physical therapy and acupuncture are in general less effective. There is thus clearly a need for better strategies, e.g. combination of available therapies and novel approaches. PMID:11139755

    Few studies have evaluated high altitude headache (HAH) and acute mountain sickness (AMS) in military populations training at moderate (1,500-2,500 m) to high altitudes (>2,500 m). In the current study, researchers interviewed active duty personnel training at Marine Corps Mountain Warfare Training Center. Participants were asked about HAH and AMS symptoms, potential risk factors, and medications used. In a sample of 192 U.S. Navy and Marine Corps personnel, 14.6% reported AMS (Lake Louise Criteria > or = 3) and 28.6% reported HAH. Dehydration and recent arrival at altitude (defined as data collected on days 2-3) were significantly associated with AMS; decreased sleep allowance was significantly associated with HAH. Although ibuprofen/Motrin users were more likely to screen positive for AMS, among AMS-positive participants, ibuprofen/Motrin users had decreased likelihood of reporting robust AMS relative to non-ibuprofen/Motrin users (p < 0.01). These results suggest that maintenance of hydration and adequate sleep allowance may be critical performance requirements at altitude. Further, ibuprofen/Motrin may be a reasonable treatment for the symptoms of AMS and HAH, although further study is warranted. PMID:22934370

    2011-10-01

    Headache is one of the most common symptoms after traumatic brain injury (TBI), and posttraumatic headache (PTH) may be part of a constellation of symptoms that is seen in the postconcussive syndrome. PTH has no defining clinical features; currently it is classified as a secondary headache based on its close temporal relationship to the injury. A growing number of studies are characterizing PTH by using primary headache classifications. Moderate to severe PTH that is often disabling may be classified as migraine or probable migraine and is found in substantial numbers of individuals. Recent data from civilian adult, pediatric, and military populations all find that PTH may be more of a chronic problem than previously thought, with a prevalence of close to half of the injured population. In addition, if PTH definitions are strictly adhered to, then many cases of PTH may be missed, thus underestimating the scope of the problem. New headaches may be reported well after the 7 days required for diagnosis of PTH by the guidelines of the International Classification of Headache Disorders, 2nd edition. A history of headache before a head injury occurs and female gender are possible risk factors for headache after TBI. Treatment of PTH may be acute or preventive, and recommendations are made for the use of migraine-specific acute therapy when indicated. Preventive therapy may be considered when PTH is frequent, disabling, or refractory to acute therapies. Comorbid conditions should be considered when choosing an appropriate preventive therapy. The symptom of headache as a "return to play" or "return to duty" barrier must be viewed in the context of other symptoms of mild TBI. PMID:22035683

    Background : About 20% of cases of acute pancreatitis progress to a severe form, leading to high mortality rates. Several studies suggested methods to identify patients that will progress more severely. However, most studies present problems when used on daily practice. Objective : To assess the efficacy of the PANC 3 score to predict acute pancreatitis severity and its relation to clinical outcome. Methods : Acute pancreatitis patients were assessed as to sex, age, body mass index (BMI), etiology of pancreatitis, intensive care need, length of stay, length of stay in intensive care unit and mortality. The PANC 3 score was determined within the first 24 hours after diagnosis and compared to acute pancreatitis grade of the Revised Atlanta classification. Results : Out of 64 patients diagnosed with acute pancreatitis, 58 met the inclusion criteria. The PANC 3 score was positive in five cases (8.6%), pancreatitis progressed to a severe form in 10 cases (17.2%) and five patients (8.6%) died. Patients with a positive score and severe pancreatitis required intensive care more often, and stayed for a longer period in intensive care units. The PANC 3 score showed sensitivity of 50%, specificity of 100%, accuracy of 91.4%, positive predictive value of 100% and negative predictive value of 90.6% in prediction of severe acute pancreatitis. Conclusion : The PANC 3 score is useful to assess acute pancreatitis because it is easy and quick to use, has high specificity, high accuracy and high predictive value in prediction of severe acute pancreatitis.

    Puche, Miguel; Garcia, Ana; Gascón, Francisco

    2014-01-01

    Cluster headache is a severe, debilitating disorder with pain that ranks among the most severe known to humans. Patients with cluster headaches have few therapeutic options and further, 10–20% develop drug-resistant attacks. The often brief duration of cluster attacks makes abortive therapy a challenge, and preventive medications are almost always provided to patients, but the side effects of these preventive medications can be significant. The sphenopalatine ganglion (SPG) is believed to play a role in headache pain and cranial autonomic symptoms associated with cluster headache, which is a result of activation of the trigeminal-autonomic reflex. For over 100 years, the SPG has been a clinical target to treat primary headache disorders using pharmacologic and nonpharmacologic methods. Radiofrequency lesioning and nerve-resection therapies, while initially beneficial, are irreversible procedures, and the use of neurostimulation provides one method of interfacing with the neural pathways without causing permanent damage to neural tissue. SPG neurostimulation is both reversible and adjustable, and has recently been tested in both proof-of-concept work and in a randomized, sham-controlled trial for the treatment of cluster headache. A randomized, sham-controlled study of 32 patients was performed to evaluate further the use of SPG stimulation for the acute treatment of chronic cluster headache. Of the 32 patients, 28 completed the randomized experimental period. Overall, 68% of patients experienced an acute response, a frequency response, or both. In this study the majority of adverse events were related to the implantation procedure, which typically resolved or remained mild in nature at 3 months following the implant procedure. This and other studies highlight the promise of using SPG stimulation to treat the pain-associated cluster headache. SPG stimulation could be a safe and effective option for chronic cluster headache.

    This study is to present a psychopathological analysis of complex hallucinatory symptoms--without consciousness breaking up in confusional state--occurring in patients with acute Guillain-Barré's syndrome diagnosis requiring neurological intensive care. Finally the patients experience an unitary and closed situation "close to dream without being dream". This experience is corresponding to the semeiology of the "oneiroid experience" (Mayer-Gross, 1924). The "oneiroid experience" appears to be of syndromic nature independent of any etiological and/or nosological classification. But its conceptualization does probably need widening: the oneiroid world appears to be a creation of a primitive function which inserts us in the world before any science or verification.

    We describe a patient with 50 per cent, third degree flame burns who had a history of paint thinner inhalation for over 10 years. Moreover, chlorpromazine had been administered for the treatment of insomnia caused by chronic thinner intoxication. He developed oliguric acute renal failure soon after the burn injury, although adequate resuscitation therapy was given, and survived following frequent haemodialysis. Although survival from acute renal failure after severe burns is rare, once the diagnosis of acute renal failure has been made, haemodialysis should be instituted as early as possible. Furthermore, in a severely burnt patient with episodes of chronic and acute intoxication from organic chemicals or drugs which may have caused renal damage, acute renal failure may occur, so that careful observation is advised.

    Increased of proinflammatory cytokines levels, including interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-alpha) on severe acute pancreatitis causes vasodilatation, increased permeability of the wall, accumulation of fluid in lung tissue and pleural sinuses. Transudate from acute parapancreatyc clusters of hot liquid and abdomen falls into the chest cavity through microscopic defects in the diaphragm due to the formation of pathological pleural-peritoneal connections or the relevant pressure gradient between the abdominal and pleural cavities. Remediation and removal of acute parapancreatyc clusters combined with the use of a multicomponent drug infusion therapy Cytoflavin provide a reduction in the frequency of pulmonary complications of acute pancreatitis from 48.3 to 31.0%. Use of the drug Cytoflavin reduces the severity of endogenous intoxication and mortality from acute lung injury from 12.9 to 6.1%. PMID:26521460

At the same time, there has been a resurgence in the incidence of kernicterus. We report the case of a term male infant who presented to our emergency department at 4 days of age with severe jaundice and who subsequently died with autopsy findings of kernicterus. We review the infant's presentation and hospital course, diagnostic and therapeutic interventions, and autopsy findings. In the current era of increased frequency of breast-feeding, shortened hospital stays, and inconsistent follow-up after hospital discharge, emergency department physicians should be alerted to the rare but increasing occurrence of severe hyperbilirubinemia and kernicterus.

    The diagnosis of primary headache disorders is clinical and based on the diagnostic criteria of the International Headache Society (ICHD-3-beta). However several brain conditions may mimic primary headache disorders and laboratory investigation may be needed. This necessity occurs when the treating physician doubts for the primary origin of headache. Features that represent a warning for a possible underlying disorder causing the headache are new onset headache, change in previously stable headache pattern, headache that abruptly reaches the peak level, headache that changes with posture, headache awakening the patient, or precipitated by physical activity or Valsalva manoeuvre, first onset of headache ≥50 years of age, neurological symptoms or signs, trauma, fever, seizures, history of malignancy, history of HIV or active infections, and prior history of stroke or intracranial bleeding. All national headache societies and the European Headache Alliance invited to review and comment the consensus before the final draft. The consensus recommends brain MRI for the case of migraine with aura that persists on one side or in brainstem aura. Persistent aura without infarction and migrainous infarction require brain MRI, MRA and MRV. Brain MRI with detailed study of the pituitary area and cavernous sinus, is recommended for all TACs. For primary cough headache, exercise headache, headache associated with sexual activity, thunderclap headache and hypnic headache apart from brain MRI additional tests may be required. Because there is little and no good evidence the committee constructed a consensus based on the opinion of experts, and should be treated as imperfect. PMID:26857820

In this article, the evidence-based treatment recommendations of the German Migraine and Headache Society for the different idiopathic headache disorders including trigeminal neuralgia are described. In addition, for most headache disorders acute and preventive medication has to be differentiated. It has to be noted that acute mediation against headache should not be taken too frequently and that in chronic headache disorders most often only a multimodal treatment results in a sufficient pain reduction.

    Patients with acute pancreatitis have elevated nutritional needs due to increased energy expenditure and catabolism. It is a clinical challenge to provide adequate nutrition to these patients while maintaining gut function, preventing pancreatic stimulation, and minimizing the risk of septic and metabolic complications associated with nutritional support. We present the case of a patient who had severe acute pancreatitis and was initially given total parenteral nutrition. After a period of initial improvement, he developed hyperglycemia, bacteremia, and sepsis. Parenteral nutrition was discontinued and infection was treated with antibiotics. Subsequent nutritional support consisted of enteral feeding with an elemental diet infused via a nasojejunal feeding tube. His condition improved gradually and he made a full recovery. This case illustrates the difficulties encountered while managing a case of severe acute pancreatitis and provides an evidence based approach to the nutritional management of severe acute pancreatitis in the intensive care unit setting.

    The role of liver transplantation (LT) in acute liver failure (ALF) complicated by severe acute pancreatitis is still unclear. We here report a case of deceased-donor LT for idiopathic ALF accompanied by severe acute pancreatitis. A 58-year-old man with no history of liver disease presented with idiopathic ALF and acute pancreatitis. After careful consideration, he received a liver from a deceased donor. Following surgery, the patient's liver function rapidly reverted to normal level and the acute pancreatitis simultaneously subsided. The patient later developed a pancreatic pseudocyst, which was treated successfully with combination interventional radiology. LT can be considered for ALF associated with severe acute pancreatitis if there is no clinical evidence of an absolute contraindication for organ transplantation, such as systemic or local infection. Moreover, we recommend a close follow-up by ultrasonography to allow early detection and treatment of pancreatic pseudocysts following surgery. PMID:27600056

    2009-01-01

    Acute severe asthma is one of the most common medical emergency situations in childhood, and physicians caring for acutely ill children are regularly faced with this condition. In this article we present a summary of the pathophysiology as well as guidelines for the treatment of acute severe asthma in children. The cornerstones of the management of acute asthma in children are rapid administration of oxygen, inhalations with bronchodilators and systemic corticosteroids. Inhaled bronchodilators may include selective b2-agonists, adrenaline and anticholinergics. Additional treatment in selected cases may involve intravenous administration of theophylline, b2-agonists and magnesium sulphate. Both non-invasive and invasive ventilation may be options when medical treatment fails to prevent respiratory failure. It is important that relevant treatment algorithms exist, applicable to all levels of the treatment chain and reflecting local considerations and circumstances. PMID:19732437

    Posttraumatic headaches are one of the most common and controversial secondary headache types. After mild head injury, more than 50% of people develop a postconcussion syndrome which has been controversial for more than 150 years. Headache is estimated as present in 30% to 90% of patients after mild head injury. Most headaches are of the tension type, although migraines can increase in frequency or occur acutely or chronically de novo. A review is provided of headaches in civilians, soldiers after blast trauma, athletes, and post-craniotomy including pathogenesis. The treatments are the same as for the primary phenotypes.

    Postpartum headache is described as headache and neck or shoulder pain during the first 6 weeks after delivery. Common causes of headache in the puerperium are migraine headache and tension headache; other causes include pre-eclampsia/eclampsia, post-dural puncture headache, cortical vein thrombosis, subarachnoid hemorrhage, posterior reversible leukoencephalopathy syndrome, brain tumor, cerebral ischemia, meningitis, and so forth. Idiopathic intracranial hypertension (IIH) is a rare cause of postpartum headache. It is usually associated with papilledema, headache, and elevated intracranial pressure without any focal neurologic abnormality in an otherwise healthy person. It is more commonly seen in obese women of reproductive age group, but rare during pregnancy and postpartum. We present a case of IIH who presented to us 18 days after cesarean section with severe headache and was successfully managed. PMID:26818168

    2014-01-01

    Metamizole or dipyrone is a pyrazolone derivative that belongs to the non-steroidal anti-inflammatory drugs. Its main side-effect is hematological toxicity. Thrombocytopenia due to metamizole is rare and is usually associated with the involvement of the two other blood series. Drug-induced thrombocytopenia is more frequently related to immune mechanisms, and the diagnosis is still largely made by exclusion of other causes and by correlation of timing of thrombocytopenia with the administration of drug. Metamizole may cause acute renal failure due to hemodynamic renal failure/acute tubular necrosis and/or acute tubulointerstitial nephritis. We report a case of acute renal failure and severe thrombocytopenia after metamizole. As far as we know, this combination of adverse effects from this drug has not been reported previously.

  16. Is ketamine a lifesaving agent in childhood acute severe asthma?

    PubMed Central

    Hendaus, Mohamed A; Jomha, Fatima A; Alhammadi, Ahmed H

    2016-01-01

    Children with acute severe asthma exacerbation are at risk of developing respiratory failure. Moreover, conventional aggressive management might be futile in acute severe asthma requiring intubation and invasive ventilation. The aim of this review is to detail evidence on the use of ketamine in childhood asthma exacerbations. A search of the MEDLINE, EMBASE, and Cochrane databases was performed, using different combinations of the following terms: ketamine, asthma, use, exacerbation, and childhood. In addition, we searched the references of the identified articles for additional articles. We then reviewed titles and included studies that were relevant to the topic of interest. Finally, the search was limited to studies published in English and Spanish from 1918 to June 2015. Due to the scarcity in the literature, we included all published articles. The literature reports conflicting results of ketamine use for acute severe asthma in children. Taking into consideration the relatively good safety profile of the drug, ketamine might be a reasonable option in the management of acute severe asthma in children who fail to respond to standard therapy. Furthermore, pediatricians and pediatric emergency clinicians administering ketamine should be knowledgeable about the unique actions of this drug and its potential side effects. PMID:26955277

  17. Diagnosis and management of headache attributed to airplane travel.

    PubMed

    2013-03-01

    The headache attributed to airplane travel, also named "airplane headache", is characterized by the sudden onset of a severe head pain exclusively in relation to airplane flights, mainly during the landing phase. Secondary causes, such as upper respiratory tract infections or acute sinusitis, must be ruled out. Although its cause is not thoroughly understood, sinus barotrauma should be reasonably involved in the pathophysiological mechanisms. Furthermore, in the current International Classification of Headache Disorders, rapid descent from high altitude is not considered as a possible cause of headache, although the onset of such pain in airplane travellers or aviators has been well known since the beginning of the aviation era. On the basis of a survey we conducted with the courteous cooperation of people who had experienced this type of headache, we proposed diagnostic criteria to be added to the forthcoming revision of the International Classification of Headache Disorders. Their formal validation would favour further studies aimed at improving knowledge of the pathophysiological mechanisms involved and at implementing preventative measures. PMID:23335028

  18. Headaches in patients with shunts.

    Rekate, Harold L; Kranz, Dory

    2009-03-01

    Headache is one of the most common afflictions suffered by humans. Headache in patients with a shunt triggers a series of events that includes utilization of expensive technologies and often potentially dangerous surgical intervention. The purpose of this study was to determine the incidence of headaches in patients with shunts and, hopefully, the relationship of those headache disorders to the treatment of hydrocephalus. The Hydrocephalus Association maintains a self-reporting database recorded from individuals treated for hydrocephalus and their families. This database was mined to determine the incidence of severe headaches requiring treatment and interfering with normal life in patients who have been treated for hydrocephalus. There were 1,242 responders between the ages of 19 months and 45 years of age. Of these, 1,233 answered the question, "Do you or your family member suffer from (does your child complain of) frequent or chronic headaches?" This subset forms the basis of this study. Three groups were defined by age: children (19 months-12 years), adolescents (13 years-19 years), and young adults (20 years-45 years). Most respondents were initially treated during infancy (before 18 months of age); 84% of children and 69% of both adolescents and young adults were treated very early in life. Severe headaches became a more frequent problem as the age of the population treated for hydrocephalus increased. In terms of frequency and severity of headaches, direct comparisons with epidemiologic studies of normal populations are difficult because of the limitations of data available in the database. However, it is likely that this population has a higher incidence of severe headaches than normal populations. The cost of management of headaches in this population is very high, and the patients are at risk throughout life. Early treatment decisions have a significant effect on later quality of life.

    Frequency of acute pulmonary embolism episodes has been previously shown to correlate significantly with meteorological factors in the period preceding their occurrence. The purpose of the study was to analyze the relation of meteorological factors and the severity of acute pulmonary embolism, expressed by the CT-based pulmonary obstruction score. A retrospective analysis of medical data of 182 consecutive patients with acute pulmonary embolism diagnosed with CT pulmonary angiography was performed. Severity of pulmonary obstruction was assessed by analysis of CT pulmonary angiography examinations, and defined with pulmonary obstruction score by Qanadli et al. The study group was divided into low (L group, 95 patients) and high PE severity (H group, 87 patients), with a cutoff value of 50% of maximum pulmonary obstruction score. Meteorological data collected for the relevant time period were: air temperature, humidity, atmospheric pressure, visibility, wind speed and precipitation. No significant differences in seasonal distribution of pulmonary embolism episodes were observed. Episodes of more severe pulmonary embolism were preceded by periods of lower atmospheric pressure (1,016.35 hPA for group H, vs. 1,016.35 hPa for group L, p = 0.022). No significant relations between other meteorological factors and severity of PE were observed. The reported finding shows the need of further research on the nature of meteorological factors influence on the course of pulmonary embolism, which should be analyzed not ony regarding the frequency, but also severity of PE episodes.

    Chronic Daily Headache is a descriptive term that includes disorders with headaches on more days than not and affects 4% of the general population. The condition has a debilitating effect on individuals and society through direct cost to healthcare and indirectly to the economy in general. To successfully manage chronic daily headache syndromes it is important to exclude secondary causes with comprehensive history and relevant investigations; identify risk factors that predict its development and recognise its sub-types to appropriately manage the condition. Chronic migraine, chronic tension-type headache, new daily persistent headache and medication overuse headache accounts for the vast majority of chronic daily headaches. The scope of this article is to review the primary headache disorders. Secondary headaches are not discussed except medication overuse headache that often accompanies primary headache disorders. The article critically reviews the literature on the current understanding of daily headache disorders focusing in particular on recent developments in the treatment of frequent headaches.

    Non-traumatic rhabdomyolysis is a rare complication of acute pancreatitis. One of the major risk factors of both acute pancreatitis and rhabdomyolysis is alcohol abuse. However, only a few studies have reported the prognosis and association of severe acute pancreatitis (SAP) and rhabdomyolysis in alcohol abuse patients. In the present study, we report two cases presenting with SAP complicated by rhabdomyolysis following high-dose alcohol intake. The disease onset, clinical manifestations, laboratory data, diagnosis and treatment procedure of each patient were recorded, and the association with rhabdomyolysis was analyzed. Alcohol consumption was the most predominant cause of SAP and rhabdomyolysis in these patients. SAP-related rhabdomyolysis was primarily induced by the toxicity associated with pancreatic necrosis. The laboratory tests revealed that the concentration of serum creatine kinase (CK) and myoglobin increased and acute renal failure symptoms were present, which provided an exact diagnosis for SAP-induced rhabdomyolysis. Rhabdomyolysis and subsequent hypermyoglobinuria severely impaired kidney function and aggravated hypocalcemia. The therapy of early stage SAP complicated by rhabdomyolysis involved liquid resuscitation support. When first stage treatment fails, blood purification should be performed immediately. Both patients developed multiple organ failure (MOF) and succumbed to the disease. Considering the two cases presented, we conclude that alcohol-related SAP complicated by rhabdomyolysis may have a poor clinical prognosis. PMID:23251265

    Patients with severe primary headache may benefit from consultation with headache specialists, but doctor attendance rates in Japan are very low. More headache patients might consult headache specialists if these specialists were more widely recognized by the public. To determine what information prompted patients to seek consultation with a headache specialist, we questioned 256 primary headache patients about the source of the helpful information concerning consultation with headache specialists. From 191 patients, a total of 235 responses to the questionnaire were obtained. The most common response was 'websites' (33.2%), followed by 'professionals' (23.8%), 'acquaintances' (20.9%), 'print media' (6.8%) and 'TV/radio' (3.4%). Patients who indicated websites showed the most severe pain and highest impact of headache, and accounted for 52.4% of those with cluster headaches. Development of websites concerning headache specialists would seem likely to increase doctor attendance rates for patients with primary headache. PMID:19515123

    2001-04-01

    This study focuses on patients with severe acute pancreatitis complicated by organ failure within the initial phase of the disease. Data of 158 patients with severe acute pancreatitis (SAP) admitted to hospital within 72 hours after onset of symptoms were prospectively documented and analyzed for the occurrence of early severe acute pancreatitis (ESAP). ESAP was defined as presence of organ failure (OF) at admission. Forty-seven (30%) patients had ESAP, compared with 111 patients without OF (SAP group). In a multivariate analysis, the main factor predisposing to ESAP was the presence of extended pancreatic necrosis (odds ratio, 3.8), whereas biliary pancreatitis was associated with a slightly lower risk compared with alcoholic pancreatitis (odds ratio, 0.34). Compared with SAP, patients with ESAP more frequently developed intractable organ failure, which posed the indication for surgical treatment. Surgical necrosectomy due to progressive OF had to be performed in 89% of the ESAP patients and in 60% of the SAP patients. The incidence of infected pancreatic necrosis did not differ between both groups (23 vs. 21%). Mortality was significantly higher in ESAP (42 vs. 14%; p = 0.0003). ESAP is characterized by the presence of extended pancreatic necrosis and a complicated clinical course. Intractable organ failure is a frequent finding. Given the poor prognosis of ESAP, these patients should be treated in specialized intensive care units. PMID:11291929

    Headache occasionally occurs during or after scuba diving. Although its significance often is benign, headache may signal a serious neurological disorder in some circumstances. In addition to the usual causes of headache, the diagnostic evaluation should consider otic and paranasal sinus barotrauma, arterial gas embolism, decompression sickness, carbon dioxide retention, carbon monoxide toxicity, hyperbaric-triggered migraine, cervical and temporomandibular joint strain, supraorbital neuralgia, carotid artery dissection, and exertional and cold stimulus headache syndromes. Focal neurologic symptoms, even in the migraineur, should not be ignored, but rather treated with 100% oxygen acutely and referred without delay to a facility with a hyperbaric chamber.

    Approximately 20% of patients with acute pancreatitis develop a severe disease associated with complications and high risk of mortality. The purpose of this study is to review pathogenesis and prognostic factors of severe acute pancreatitis (SAP). An extensive medline search was undertaken with focusing on pathogenesis, complications and prognostic evaluation of SAP. Cytokines and other inflammatory markers play a major role in the pathogenesis and course of SAP and can be used as prognostic markers in its early phase. Other markers such as simple prognostic scores have been found to be as effective as multifactorial scoring systems (MFSS) at 48 h with the advantage of simplicity, efficacy, low cost, accuracy and early prediction of SAP. Recently, several laboratory markers including hematocrit, blood urea nitrogen (BUN), creatinine, matrix metalloproteinase-9 (MMP-9) and serum amyloid A (SAA) have been used as early predictors of severity within the first 24 h. The last few years have witnessed a tremendous progress in understanding the pathogenesis and predicting the outcome of SAP. In this review we classified the prognostic markers into predictors of severity, pancreatic necrosis (PN), infected PN (IPN) and mortality. PMID:18205255

    PubMed

    2000-01-01

    Several pathophysiological mechanisms are involved in the development of the inflammatory necrotizing process that takes place in the retroperitoneal area during the early phase of acute pancreatitis. They include premature intraglandular activation of pancreatic proenzymes (zymogens) and in particular trypsin, early microcirculatory impairment with subsequent ischaemia/reperfusion and overstimulation of immune effector cells. Although intra-acinar or interstitial activation of trypsinogen is most probably the trigger of acute pancreatitis, in recent years much emphasis has been put on the role of leukocytes. Based on numerous experimental and human data several pro-inflammatory mediators including cytokines, arachidonic acid derivatives, activated oxygen species and proteases are released locally by overactivated neutrophils and monocytes/macrophages among other cells. They are now believed to play a central role in the development of pancreatic necrosis and, once they gain access to the systemic circulation, in the emergence of early multisystem organ failure. However the sequential and relative contribution of each of these 3 pathophysiological mechanisms remain controversial and the precise identification of the mediators incriminated in local and remote tissue injury is still awaited. Severe acute pancreatitis still carries a mortality of 20% to 30%. With advances in intensive care management 80% of the deaths occur somewhat late in the attack due to infected pancreatic necrosis. Nevertheless early remote organ failures still remain a lifethreatening condition for most of these patients. A peritoneal exudate rich in activated lipolytic and proteolytic enzymes, vasoactive substances and several other pro-inflammatory mediators collect in over 60% of the patients with severe acute pancreatitis. On the basis of favourable animal experiments early percutaneous or surgical peritoneal lavage with or without the addition of antiproteases has been carried out in human

  11. Severe acute malnutrition during emergencies: burden management, and gaps.

    2014-06-01

    Natural and man-made disasters, including floods, droughts, earthquakes, and armed conflicts, create nutrition crises. Unfortunately, the frequency and severity of such disasters have been increasing since the beginning of the 20th century, and their contribution to the burden of acute malnutrition is increasing every year. However, their contribution to the burden of acute malnutrition is underrecognized due to the ways in which global statistics are built and causes of death are reported. Fortunately, the success of the current protocol for treatment of severe acute malnutrition (SAM) and the integrated approach to treatment has created a momentum allowing expanded coverage of treatment of SAM, especially in humanitarian emergency contexts. For this progress to be maintained and accelerated, changes in nutrition information systems at the national and global levels are needed, and the persisting barriers to the expansion and integration of treatment of SAM into routine health systems need to be removed. Emergency funding approaches and objectives have to include sustaining and amplifying the achievements of the short-term palliative interventions. Nutrition programs implemented in emergency contexts have the capacity to contribute to answering priority research questions, and this capacity should be more optimally utilized. PMID:25069293

    Severe diarrheal illness in children can be attributed to a number of different microbiological agents. Without appropriate microbiological testing of stool samples, patients who present with multiple days of severe diarrhea might have a delay in proper diagnosis and treatment. Here, we report a case of an immunocompetent pediatric patient presenting with acute cryptosporidiosis. Humans and bovine species are known hosts of cryptosporidium and several studies have evaluated the zoonotic transmission of cryptosporidium from cattle to humans. Adding diagnostic tests for cryptosporidium like Ziehl-Neelsen staining of stool or fecal rapid antigen detection techniques should be considered in the workup of patients presenting with undifferentiated, severe diarrheal illness, especially in those who have close contact with livestock.

    Twenty-one patients experienced headache related to sexual activity. Two varieties of headache could be distinguished from the clinical histories. The first, developing as sexual excitement mount, had the characteristics of muscle contraction headache. The second, severe, throbbing or 'explosive' in character, occurring at the time of orgasm, was presumably of vascular origin associated with a hyperdynamic circulatory state. Two of the patients with the latter type of headache had each experienced episodes of cerebral vascular insufficiency on one occasion which subsequently resolved. A third patient in this category had a past history of drop attacks. No evidence of any structural lesion was obtained on clinical examination or investigation, including cerebral angiography in seven patients. Eighteen patients have been followed up for periods of two to seven years without any serious intracranial disorder becoming apparent. While the possibility of intracranial vascular or other lesions must always be borne in mind, there appears to be a syndrome of headache associated with sexual excitement where no organic change can be demonstrated, analogous to benign cough headache and benign exertional headache.

    Acute fatty liver of pregnancy is a rare disease that affects women in the third trimester of pregnancy. Although infrequent, the disease can cause maternal mortality. The diagnosis is not always clear until the pregnancy is terminated, and significant complications, such as acute pancreatitis, can occur. Pancreatic involvement typically only occurs in severe cases after the development of hepatic and renal impairment. To date, little knowledge is available regarding how the disease causes pancreatitis. Treatment involves supportive measures and pregnancy interruption. In this report, we describe a case of a previously healthy 26-year-old woman at a gestational age of 27 wk and 6 d who was admitted with severe abdominal pain and vomiting. This case illustrates the clinical and laboratory overlap between acute fatty liver of pregnancy and pancreatitis, highlighting the difficulties in differentiating each disease. Furthermore, the hypothesis for this overlapping is presented, and the therapeutic options are discussed. PMID:25068005

    2015-01-01

    Cluster headache (CH), one of the most painful syndromes known to man, is managed with acute and preventive medications. The brief duration and severity of the attacks command the use of rapid-acting pain relievers. Inhalation of oxygen and subcutaneous sumatriptan are the two most effective acute therapeutic options for sufferers of CH. Several preventive medications are available, the most effective of which is verapamil. However, most of these agents are not backed by strong clinical evidence. In some patients, these options can be ineffective, especially in those who develop chronic CH. Surgical procedures for the chronic refractory form of the disorder should then be contemplated, the most promising of which is hypothalamic deep brain stimulation. We hereby review the pathogenesis of CH and the evidence behind the treatment options for this debilitating condition. PMID:26635477

    With 17% to 18% of women suffering from migraine headaches, clinicians will often be asked by their patients to prescribe medication. Migraine is an episodic chronic disease that is best managed with an overall treatment plan, rather than treated as an acute illness that is managed with sporadic medications. Realistic goals for the long-term management of migraine are based on patient education and an ongoing discussion between patient and provider. This article reviews the clinical presentation of migraine and recommendations for both acute and preventive treatment, including complementary therapies. "Red flags" that could be signs of more serious neurologic illness are presented. The management of migraine in pregnancy is also reviewed. PMID:16647669

    In the past few years, several endemic outbreaks of measles have been recognised, not only in children but also in adults, with severe and, occasionally, even fatal complications, possibly due to delayed diagnosis of the disease in adult medicine and decreasing vaccination rates. Furthermore, the treatment consists of supportive measures only. We present a case of severe measles pneumonitis in a 42-year-old man, a travel returnee, proven by direct virus isolation with PCR from bronchoalveolar lavage fluid. CT findings and pulmonary function testing revealed features of obstructive bronchiolitis; the patient was successfully treated with corticosteroids. He fully recovered, and lung function measurement returned to normal values. We conclude that acute measles can present as obstructive bronchiolitis and may be successfully treated with corticosteroids. PMID:26508116

    We report the case of a 27-year-old male athlete presenting with severe dyspnoea 24 hours after completing an "Ironman Triathlon." Subsequent chest radiology excluded pulmonary embolus but confirmed an acute lung injury (ALI). Echocardiography corroborated a normal brain natriuretic peptide level by demonstrating good biventricular systolic function with no regional wall motion abnormalities. He recovered well, without requiring ventilatory support, on supplemental oxygen therapy and empirical antibiotics. To date, ALI following severe physical exertion has never been described. Exercise is a form of physiological stress resulting in oxidative stress through generation of reactive oxygen/nitrogen species. In its extreme form, there is potential for an excessive oxidative stress response--one that overwhelms the body's protective antioxidant mechanisms. As our case demonstrated, oxidative stress secondary to severe physical exertion was the most likely factor in the pathogenesis of ALI. Further studies are necessary to explore the pathological consequences of exercise-induced oxidative stress. Although unproven as of yet, further research may be needed to demonstrate if antioxidant therapy can prevent or ameliorate potential life-threatening complications in the acute setting.

  19. Primary Headache Disorders: Focus on Migraine

    PubMed Central

    2011-01-01

    Migraine is the most common disabling headache disorder. Most patients with disabling tension-type headache are likely to have migraine and accordingly respond to treatments efficacious in migraine. Individuals are genetically predisposed to experiencing recurrent migraine. Evidence supports migraine to be a primarily neural and not vascular mediated disorder. 1–2% of the population have chronic daily headache associated with acute-relief medication overuse; the majority are migraineurs. The presence of acute-relief medication overuse renders preventative medication less adequately efficacious. PMID:26525886

    Severe acute respiratory syndrome (SARS) is a recently described illness of humans that has spread widely over the past 6 months. With the use of detailed epidemiologic data from Singapore and epidemic curves from other settings, we estimated the reproductive number for SARS in the absence of interventions and in the presence of control efforts. We estimate that a single infectious case of SARS will infect about three secondary cases in a population that has not yet instituted control measures. Public-health efforts to reduce transmission are expected to have a substantial impact on reducing the size of the epidemic.

    Background Chronic cluster headache (CH) is a debilitating disorder for which few well-controlled studies demonstrate effectiveness of available therapies. Non-invasive vagus nerve stimulation (nVNS) was examined as adjunctive prophylactic treatment of chronic CH. Methods PREVA was a prospective, open-label, randomised study that compared adjunctive prophylactic nVNS (n = 48) with standard of care (SoC) alone (control (n = 49)). A two-week baseline phase was followed by a four-week randomised phase (SoC plus nVNS vs control) and a four-week extension phase (SoC plus nVNS). The primary end point was the reduction in the mean number of CH attacks per week. Response rate, abortive medication use and safety/tolerability were also assessed. Results During the randomised phase, individuals in the intent-to-treat population treated with SoC plus nVNS (n = 45) had a significantly greater reduction in the number of attacks per week vs controls (n = 48) (−5.9 vs −2.1, respectively) for a mean therapeutic gain of 3.9 fewer attacks per week (95% CI: 0.5, 7.2; p = 0.02). Higher ≥50% response rates were also observed with SoC plus nVNS (40% (18/45)) vs controls (8.3% (4/48); p < 0.001). No serious treatment-related adverse events occurred. Conclusion Adjunctive prophylactic nVNS is a well-tolerated novel treatment for chronic CH, offering clinical benefits beyond those with SoC. PMID:26391457

    We have discussed several miscellaneous headache disorders not associated with structural brain disease. The first group included those headaches provoked by "exertional" triggers in various forms. These include benign cough headache, BEH, and headache associated with sexual activity. The IHS diagnostic criteria were discussed. Benign exertional headache and cough headache were discussed together because of their substantial similarities. In general, BEH is characterized by severe, short-lived pain after coughing, sneezing, lifting a burden, sexual activity, or other similar brief effort. Structural disease of the brain or skull was the most important differential diagnosis for these disorders, with posterior fossa mass lesions being identified as the most common organic etiology. Magnetic resonance imaging with special attention to the posterior fossa and foramen magnum is the preferred method for evaluating these patients. Indomethacin is the treatment of choice. The headache associated with sexual activity is dull in the early phases of sexual excitement and becomes intense at orgasm. This headache is unpredictable in occurrence. Like BEH, the headache associated with sexual activity can be a manifestation of structural disease. Subarachnoid hemorrhage must be excluded, by CT scanning and CSF examination, in patients with the sexual headache. Benign headache associated with sexual activity has been successfully treated with indomethacin and beta-blockers. The second miscellaneous group of headache disorders includes those provoked by eating something cold or food additives, and by environmental stimuli. Idiopathic stabbing headache does not have a known trigger and appears frequently in migraineurs. Its occurrence may also herald the termination of an attack of cluster headache. Indomethacin treatment provides significant relief. Three headaches triggered by substances that are eaten were reviewed: ingestion of a cold stimulus, nitrate/nitrite-induced headache

    Migraine is a common, disabling, neurovascular disorder characterized by episodic attacks of head pain and associated disability plus systemic autonomic and neurologic symptoms. The advent of the triptan class of medication in the 1990s revolutionized the acute treatment of migraine, but many migraineurs do not respond optimally or at all to triptans, have intolerable adverse effects, or have contraindications to their use. Preventive pharmacotherapy has advanced mostly through serendipity, with new drugs being found effective while being used for other indications. There remains a significant need for new medications and devices that can provide effective, rapid, and sustained pain relief without adverse effects or recurrence. Several new acute and preventive therapies for the treatment of migraine and cluster headaches have shown promise and are currently under investigation. This article covers innovative delivery mechanisms, calcitonin gene-related peptide receptor antagonists, antibodies to calcitonin gene-related peptide and its receptor, 5-HT1F receptor agonists, transient receptor potential vanilloid receptor modulators, orexin receptor antagonists, glial cell modulators, and neurostimulation.

    Headache following dural puncture is a typical complication of neuraxial analgesia and can impair the ability to perform activities of daily living up to incapacitation. The use of thin, atraumatic needles and special puncture techniques (e.g. reinsertion of the stylet) can prevent the majority of post-dural puncture headaches (PDPH). One of the most effective measures to prevent headache after accidental dural puncture is the intrathecal or epidural administration of morphine. When the diagnosis of PDPH is confirmed after excluding relevant differential diagnoses, some of which are potentially life-threatening, caffeine, theophylline and non-opioid analgesics are effective agents to reduce the severity of the symptoms. Traditional measures, such as strict bed rest and hyperhydration can no longer be recommended. If invasive treatment of the headache is warranted an epidural blood patch is still the method of choice with a high rate of success. PMID:23400710

    The ‘Other Primary Headaches’ include eight recognised benign headache disorders. Primary stabbing headache is a generally benign disorder which often co-exists with other primary headache disorders such as migraine and cluster headache. Primary cough headache is headache precipitated by valsalva; secondary cough has been reported particularly in association with posterior fossa pathology. Primary exertional headache can occur with sudden or gradual onset during, or immediately after, exercise. Similarly headache associated with sexual activity can occur with gradual evolution or sudden onset. Secondary headache is more likely with both exertional and sexual headache of sudden onset. Sudden onset headache, with maximum intensity reached within a minute, is termed thunderclap headache. A benign form of thunderclap headache exists. However, isolated primary and secondary thunderclap headache cannot be clinically differentiated. Therefore all headache of thunderclap onset should be investigated. The primary forms of the aforementioned paroxysmal headaches appear to be Indomethacin sensitive disorders. Hypnic headache is a rare disorder which is termed ‘alarm clock headache’, exclusively waking patients from sleep. The disorder can be Indomethacin responsive, but can also respond to Lithium and caffeine. New daily persistent headache is a rare and often intractable headache which starts one day and persists daily thereafter for at least 3 months. The clinical syndrome more often has migrainous features or is otherwise has a chronic tension-type headache phenotype. Management is that of the clinical syndrome. Hemicrania continua straddles the disorders of migraine and the trigeminal autonomic cephalalgias and is not dealt with in this review. PMID:23024566

    Objective To describe headache-related health resource usage in chronic and episodic migraine across six countries. Methods A web-based questionnaire eliciting data on several topics, including health resource usage, was administered to panellists with migraine from the USA, Canada, UK, Germany, France and Australia. Respondents were grouped into episodic and chronic migraine, based on reported headache phenotype and headache-day frequency. ORs were calculated, comparing usage in each country to that in the US, controlling for chronic versus episodic migraine and other factors. Results Relative to the USA, the odds of visiting a provider for headache during the preceding 3 months were significantly higher in all countries, except Germany. Respondents in France were more likely to report having a provider they typically visited for headache-related care. The odds of visiting the emergency department for headache were significantly lower in France, the UK and Germany, and hospitalisation for headache was significantly more frequent in Canada and Australia. Respondents from all countries, except Canada, were more likely to report currently using a prescription-acute treatment, and those from France were more likely to report trying more than three acute treatments. Preventive treatment use did not differ significantly. Conclusions Headache-related resource usage differed significantly between the USA and other countries. US respondents were generally less likely to report recent provider visits and use of prescription-acute treatments. They were more likely to report emergency department visits than in European countries, but less likely to report hospitalisation than in Canada and Australia. PMID:23813744

    The precise definition of a severe asthmatic exacerbation is an issue that presents difficulties. The term 'status asthmaticus' relates severity to outcome and has been used to define a severe asthmatic exacerbation that does not respond to and/or perilously delays the repetitive or continuous administration of short-acting inhaled beta(2)-adrenergic receptor agonists (SABA) in the emergency setting. However, a number of limitations exist concerning the quantification of unresponsiveness. Therefore, the term 'acute severe asthma' is widely used, relating severity mostly to a combination of the presenting signs and symptoms and the severity of the cardiorespiratory abnormalities observed, although it is well known that presentation does not foretell outcome. In an acute severe asthma episode, close observation plus aggressive administration of bronchodilators (SABAs plus ipratropium bromide via a nebulizer driven by oxygen) and oral or intravenous corticosteroids are necessary to arrest the progression to severe hypercapnic respiratory failure leading to a decrease in consciousness that requires intensive care unit (ICU) admission and, eventually, ventilatory support. Adjunctive therapies (intravenous magnesium sulfate and/or others) should be considered in order to avoid intubation. Management after admission to the hospital ward because of an incomplete response is similar. The decision to intubate is essentially based on clinical judgement. Although cardiac or respiratory arrest represents an absolute indication for intubation, the usual picture is that of a conscious patient struggling to breathe. Factors associated with the increased likelihood of intubation include exhaustion and fatigue despite maximal therapy, deteriorating mental status, refractory hypoxaemia, increasing hypercapnia, haemodynamic instability and impending coma or apnoea. To intubate, sedation is indicated in order to improve comfort, safety and patient-ventilator synchrony, while at the

    ABSTRACT Systems biology offers considerable promise in uncovering novel pathways by which viruses and other microbial pathogens interact with host signaling and expression networks to mediate disease severity. In this study, we have developed an unbiased modeling approach to identify new pathways and network connections mediating acute lung injury, using severe acute respiratory syndrome coronavirus (SARS-CoV) as a model pathogen. We utilized a time course of matched virologic, pathological, and transcriptomic data within a novel methodological framework that can detect pathway enrichment among key highly connected network genes. This unbiased approach produced a high-priority list of 4 genes in one pathway out of over 3,500 genes that were differentially expressed following SARS-CoV infection. With these data, we predicted that the urokinase and other wound repair pathways would regulate lethal versus sublethal disease following SARS-CoV infection in mice. We validated the importance of the urokinase pathway for SARS-CoV disease severity using genetically defined knockout mice, proteomic correlates of pathway activation, and pathological disease severity. The results of these studies demonstrate that a fine balance exists between host coagulation and fibrinolysin pathways regulating pathological disease outcomes, including diffuse alveolar damage and acute lung injury, following infection with highly pathogenic respiratory viruses, such as SARS-CoV.

    Background As maternal deaths have decreased worldwide, increasing attention has been placed on the study of severe obstetric complications, such as hemorrhage, eclampsia, and obstructed labor, to identify where improvements can be made in maternal health. Though access to medical care is considered to be life-saving during obstetric emergencies, data on the factors associated with health care decision-making during obstetric emergencies are lacking. We aim to describe the health care decision-making process during severe acute obstetric complications among women and their families in rural Bangladesh. Methods Using the pregnancy surveillance infrastructure from a large community trial in northwest rural Bangladesh, we nested a qualitative study to document barriers to timely receipt of medical care for severe obstetric complications. We conducted 40 semi-structured, in-depth interviews with women reporting severe acute obstetric complications and purposively selected for conditions representing the top five most common obstetric complications. The interviews were transcribed and coded to highlight common themes and to develop an overall conceptual model. Results Women attributed their life-threatening experiences to societal and socioeconomic factors that led to delays in seeking timely medical care by decision makers, usually husbands or other male relatives. Despite the dominance of male relatives and husbands in the decision-making process, women who underwent induced abortions made their own decisions about their health care and relied on female relatives for advice. The study shows that non-certified providers such as village doctors and untrained birth attendants were the first-line providers for women in all categories of severe complications. Coordination of transportation and finances was often arranged through mobile phones, and referrals were likely to be provided by village doctors.

    Background Asparaginase and steroids can cause hypertriglyceridemia in children with acute lymphoblastic leukemia (ALL). There are no guidelines for screening or management of patients with severe hypertriglyceridemia (>1000 mg/dL) during ALL therapy. Patients and Methods Fasting lipid profiles were obtained prospectively at 4 time-points for 257 children consecutively enrolled on a frontline ALL study. Risk factors were evaluated by the exact chi-square test. Details of adverse events and management of hypertriglyceridemia were extracted retrospectively. Results Eighteen of 257 (7%) patients developed severe hypertriglyceridemia. Older age and treatment with higher doses of asparaginase and steroids on the standard/high-risk arm were significant risk factors. Severe hypertriglyceridemia was not associated with pancreatitis after adjustment for age and treatment arm or with osteonecrosis after adjustment for age. However, patients with severe hypertriglyceridemia had a 2.5 to 3 times higher risk of thrombosis compared to patients without, albeit the difference was not statistical significant. Of the 30 episodes of severe hypertriglyceridemia in 18 patients, 7 were managed conservatively while the others with pharmacotherapy. Seventeen of 18 patients continued to receive asparaginase and steroids. Triglyceride levels normalized after completion of ALL therapy in all 12 patients with available measurements. Conclusion Asparaginase- and steroid-induced transient hypertriglyceridemia can be adequately managed with dietary modifications and close monitoring without altering chemotherapy. Patients with severe hypertriglyceridemia were not at increased risk of adverse events, with a possible exception of thrombosis. The benefit of pharmacotherapy in decreasing symptoms and potential complications requires further investigation. PMID:25087182

    Pancreatic necrosis complicating severe acute pancreatitis is a challenging scenario in contemporary critical care practice; it requires multidisciplinary care in a setting where there is a relatively limited evidence base to support decision making. This commentary provides a concise overview of current management of patients with infected necrosis, focusing on detection, the role of pharmacologic intervention, and the timing and nature of surgical interventions. Fine-needle aspiration of necrosis remains the mainstay for establishment of infection. Pharmacological intervention includes antibiotic therapy as an adjunct to surgical debridement/drainage and, more recently, drotrecogin alfa. Specific concerns remain regarding the suitability of drotrecogin alfa in this setting. Early surgical intervention is unhelpful; surgery is indicated when there is strong evidence for infection of necrotic tissue, with the current trend being toward 'less drastic' surgical interventions.

    Obese patients have worse outcomes during acute pancreatitis (AP). Previous animal models of AP have found worse outcomes in obese rodents who may have a baseline proinflammatory state. Our aim was to study the role of acute lipolytic generation of fatty acids on local severity and systemic complications of AP. Human postpancreatitis necrotic collections were analyzed for unsaturated fatty acids (UFAs) and saturated fatty acids. A model of biliary AP was designed to replicate the human variables by intraductal injection of the triglyceride glyceryl trilinoleate alone or with the chemically distinct lipase inhibitors orlistat or cetilistat. Parameters of AP etiology and outcomes of local and systemic severity were measured. Patients with postpancreatitis necrotic collections were obese, and 13 of 15 had biliary AP. Postpancreatitis necrotic collections were enriched in UFAs. Intraductal glyceryl trilinoleate with or without the lipase inhibitors resulted in oil red O–positive areas, resembling intrapancreatic fat. Both lipase inhibitors reduced the glyceryl trilinoleate–induced increase in serum lipase, UFAs, pancreatic necrosis, serum inflammatory markers, systemic injury, and mortality but not serum alanine aminotransferase, bilirubin, or amylase. We conclude that UFAs are enriched in human necrotic collections and acute UFA generation via lipolysis worsens pancreatic necrosis, systemic inflammation, and injury associated with severe AP. Inhibition of lipolysis reduces UFA generation and improves these outcomes of AP without interfering with its induction. PMID:24854864

    Headaches are universal experiences and among the most common disorders. While headache may be physiological in the acute setting, it can become a pathological and persistent condition. The mechanisms underlying the transition from episodic to chronic pain have been the subject of intense study. Using physiological and imaging methods, researchers have identified a number of different forms of neural plasticity associated with migraine and other headaches, including peripheral and central sensitization, and alterations in the endogenous mechanisms of pain modulation. While these changes have been proposed to contribute to headache and pain chronification, some findings are likely the results of repetitive noxious stimulation, such as atrophy of brain areas involved in pain perception and modulation. In this review, we provide a narrative overview of recent advances on the neuroimaging, electrophysiological and genetic aspects of neural plasticity associated with the most common forms of chronic headaches, including migraine, cluster headache, tension-type headache, and medication overuse headache.

    Headache and sleep problems are both some of the most commonly reported symptoms in clinical practice. There is a clear association between chronic headache and sleep disorders, especially headaches occurring during the night or early morning. Identification of sleep problems in chronic headache patients is worthwhile because treatment of sleep disorders among chronic headache patients may be followed by improve of the headache. Morning headache has been recognised as an obstructive sleep apnoea related symptom. Treatment with continuous positive airway pressure usually reduced headache, however, we often encounter obstructive sleep apnoea patients who present various characteristics of morning headache that often do not fulfil the criteria for "sleep apnoea headache" according to the International Classification of Headache Disorders: 2nd edition (ICHD-2) criteria. The pathophysiologic background for a relation between obstructive sleep apnoea and morning headache is multifactorial. We should also be noted that tension-type headache and migraine might be coexisted in obstructive sleep apnoea patients. In addition, we review the relationship between migraine and sleep disorders such as restless legs syndrome, narcolepsy and parasomnia (dream enacting behaviour) including our studies. PMID:25672689

    A close association between pain, depression and disability has been shown. However, the neurometabolic correlates of this association have been barely investigated in disease states. Episodic cluster headache is a severe headache syndrome and represents a suitable disease model for the investigation of episodic pain. The aim of this study was to explore the relationship between depression and disability as well as pain scores and brain metabolism in patients with cluster headache during the disease period with repetitive pain attacks, but outside an acute attack. Thirteen patients with cluster headache underwent 2-[fluorine-18]-fluoro-2-deoxy-d-glucose positron emission (FDG-PET) and completed questionnaires on depression and disability as well as a pain visual analogue rating scale (VAS). A positive correlation between the depression scores and glucose metabolism was observed in the insular cortex. A positive correlation between the pain disability scores and brain metabolism was detected in the amygdala. The same applied to the pain visual analogue rating scores. Our data underline the association between severe episodic pain, depression and disability. In addition to this clinical observation, our results stress the importance of the insula and amygdala in pain processing and suffering. PMID:20737158

    Peroxisome proliferator-activated receptor-γ (PPAR-γ) ligand regulates adipocyte differentiation and insulin sensitivity, and exerts antihyperlipidemic and anti-inflammatory effects. However, the mechanisms by which PPAR-γ ligands affect hyperlipidemia with severe acute pancreatitis (SAP) have not been fully elucidated. The present study investigated the effects of rosiglitazone, a PPAR-γ ligand, on hyperlipidemia with SAP in a rat model. The hyperlipidemia was induced with a high-fat diet and SAP was induced by the administration of sodium taurocholate (TCA). The hyperlipidemia was shown to aggravate the severity of the sodium taurocholate-induced SAP. However, rosiglitazone demonstrated significant antihyperlipidemic and anti-inflammatory effects in the rats with high-lipid diet-induced hyperlipidemia and SAP. PMID:24137303

    AIM: To investigate the severity of acute pancreatitis (AP) is associated to the intensity of leukocyte activation, inflammatory up-regulation and microcirculatory disruption associated to ischemia-reperfusion injury. Microvascular integrity and inhibition of pro-inflammatory mediators are key-factors in the evolution of AP. Relaxin is an insulin-like hormone that has been attributed vasorelaxant properties via the nitric oxide pathway while behaving as a glucocorticoid receptor agonist. METHODS: AP was induced by the bilio-pancreatic duct-outlet-exclusion closed-duodenal-loops model. Treatment with relaxin was done at different time-points. Nitric oxide synthase inhibition by L-NAME and glucocorticoid receptor (GR) blockage by mifepristone was considered. AP severity was assessed by biochemical and histopathological analyses. RESULTS: Treatment with relaxin reduced serum amylase, lipase, C-reactive protein, IL-6, IL-10, hsp72, LDH and 8-isoprostane as well as pancreatic and lung myeloperoxidase. Acinar and fat necrosis, hemorrhage and neutrophil infiltrate were also decreased. ATP depletion and ADP/ATP ratio were reduced while caspases 2-3-8 and 9 activities were increased. L-NAME and mifepristone decreased the efficiency of relaxin. CONCLUSION: Relaxin resulted beneficial in the treatment of AP combining the properties of a GR agonist while preserving the microcirculation and favoring apoptosis over necrosis. PMID:16570348

    Severe acute pancreatitis (SAP), which is the most serious type of this disorder, is associated with high morbidity and mortality. SAP runs a biphasic course. During the first 1-2 wk, a pro-inflammatory response results in systemic inflammatory response syndrome (SIRS). If the SIRS is severe, it can lead to early multisystem organ failure (MOF). After the first 1-2 wk, a transition from a pro-inflammatory response to an anti-inflammatory response occurs; during this transition, the patient is at risk for intestinal flora translocation and the development of secondary infection of the necrotic tissue, which can result in sepsis and late MOF. Many recommendations have been made regarding SAP management and its complications. However, despite the reduction in overall mortality in the last decade, SAP is still associated with high mortality. In the majority of cases, sterile necrosis should be managed conservatively, whereas in infected necrotizing pancreatitis, the infected non-vital solid tissue should be removed to control the sepsis. Intervention should be delayed for as long as possible to allow better demarcation and liquefaction of the necrosis. Currently, the step-up approach (delay, drain, and debride) may be considered as the reference standard intervention for this disorder. PMID:25320523

    Ice pick headache, also called idiopathic or primary stabbing headache, is a unique headache type associated with ultra-brief stabs of pain, most commonly in the frontal or temporal area. It occurs predominantly in women and is estimated to affect 2-35 % of the population. Unlike other headache types of short duration, such as short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT), ice pick headache is not associated with any cranial autonomic symptoms but has been known to occur with nausea, vomiting, photophobia, and dizziness. It exists in two forms: primary and secondary, with examples of secondary causes being herpes zoster meningoencephalitis, meningiomas, stroke, and multiple sclerosis. Ice pick headache is one of the "indomethacin responsive headaches," but up to 35 % of patients fail to show significant benefit with that treatment. Other treatment options include gabapentin, cyclooxygenase-2 inhibitors, melatonin, and external hand warming. PMID:27038969

Greater occipital nerve block, the most widely used local anesthetic procedure in headache conditions, is particularly effective, safe, and easy to perform in the office. Adverse effects are few and infrequent. These procedures can result in rapid relief of pain and allodynia, and effects last for several weeks or months. Use of nerve block procedures and potentially onabotulinum toxin therapy should be expanded for patients with intractable headache disorders who may benefit, although more studies are needed for efficacy and clinical safety.

    Medically refractory chronic cluster headache (CH) is a severely disabling headache condition for which several surgical procedures have been proposed as a prophylactic treatment. None of them have been evaluated in controlled conditions, only open studies and case series being available. Destructive procedures (radiofrequency lesioning, radiosurgery, section) and microvascular decompression of the trigeminal nerve or the sphenopalatine ganglion (SPG) have induced short-term improvement which did not maintain on long term in most of the patients. They carried a high risk of complications, including severe sensory loss and neuropathic pain, and consequently should not be proposed in first intention.Deep brain stimulation (DBS), targeting the presumed CH generator in the retro-hypothalamic region or fibers connecting it, decreased the attack frequency >50 in 60 % of the 52 patients reported. Complications were infrequent: gaze disturbances, autonomic disturbances, and intracranial hemorrhage (2).Occipital nerve stimulation (ONS) was efficient (decrease of attack frequency >50 %) in about 70 % of the 60 patients reported, with a low risk of complications (essentially hardware related). Considering their respective risks, ONS should be proposed first and DBS only in case of ONS failure.New on-demand chronically implanted SPG stimulation seemed to be efficient to abort CH attacks in a pilot controlled trial, but its long-term safety needs to be further studied.

    Cluster headache is characterized by disabling stereotyped headache. Early diagnosis allows appropriate treatment, unfortunately diagnostic errors are frequent. The main differential diagnoses are other primary or essential headaches. Migraine, more frequent and whose diagnosis is carried by excess, trigeminal neuralgia or other trigemino-autonomic cephalgia. Vascular or tumoral underlying condition can mimic cluster headache, neck and brain imaging is recommended, ideally MRI. PMID:26549687

    The aetiology of cluster headache is partially unknown. Three areas are involved in the pathogenesis of cluster headache: the trigeminal nociceptive pathways, the autonomic system and the hypothalamus. The cluster headache attack involves activation of the trigeminal autonomic reflex. A dysfunction located in posterior hypothalamic gray matter is probably pivotal in the process. There is a probable association between smoke exposure, a possible genetic predisposition and the development of cluster headache. PMID:26470883

    The Headache Classification Committee of the International Headache Society has developed a new classification system for headache, cranial neuralgia, and facial pain. The value of the classification for the practising clinician is that it forces him or her to take a more careful history in order to determine the nature of the headache. This article reviews the classification system and gives examples of case histories and subsequent diagnoses. PMID:21221276

    Peripheral neuropathy is a common complication of arsenic toxicity. Symptoms are usually mild and reversible following discontinuation of treatment. A more severe chronic sensorimotor polyneuropathy characterized by distal axonal-loss neuropathy can be seen in chronic arsenic exposure. The clinical course of arsenic neurotoxicity in patients with coexistence of thiamine deficiency is only anecdotally known but this association may potentially lead to severe consequences. We describe a case of acute irreversible axonal neuropathy in a patient with hidden thiamine deficiency who was treated with a short course of arsenic trioxide for acute promyelocytic leukemia. Thiamine replacement therapy and arsenic trioxide discontinuation were not followed by neurological recovery and severe polyneuropathy persisted at 12-month follow-up. Thiamine plasma levels should be measured in patients who are candidate to arsenic trioxide therapy. Prophylactic administration of vitamin B1 may be advisable. The appearance of polyneuropathy signs early during the administration of arsenic trioxide should prompt electrodiagnostic testing to rule out a pattern of axonal neuropathy which would need immediate discontinuation of arsenic trioxide.

    Severe acute respiratory syndrome (SARS) is a highly infectious, rapidly progressive, emerging disease. Early diagnosis and preventive measures are key for treatment and minimization of secondary spread. In the context of the armed forces, aggressive containment measures are essential to prevent an outbreak. In this study, we present the first reported case, to our knowledge, of SARS in a naval diver. The special physical requirements for divers and the potential complications associated with deep sea diving necessitate extensive investigation before certification of fitness for diving after SARS. In the early recovery period, potential problems during diving are caused by inadequate lung ventilation in relation to exercise level and increased breathing resistance attributable to weak respiratory muscles, with corresponding risk of hypoxia and hypercapnia, as well as decreased ability to respond to nonrespiratory problems during diving. Problems in the late recovery period include increased risk of diving complications (such as pulmonary barotrauma) resulting from fibrosis and scarring within the lung parenchyma, which are known complications of SARS. From our experience, we suggest that computed tomographic scans of the thorax, lung function tests, and careful follow-up monitoring should play a vital role in the assessment of patients during the convalescent period, before certification of fitness to dive.

    Severe acute respiratory syndrome (SARS) is a newly described respiratory infection with pandemic potential. The causative agent is a new strain of coronavirus most likely originating from wild animals. This disease first emerged in November 2002 in Guangdong Province, China. Early in the outbreak the infection had been transmitted primarily via household contacts and healthcare settings. In late February 2003 the infection was transmitted to Hong Kong when an infected doctor from the mainland visited there. During his stay in Hong Kong at least 17 guests and visitors were infected at the hotel at which he stayed. By modern day air travel, the infection was rapidly spread to other countries including Vietnam, Singapore and Canada by these infected guests. With the implementation of effective control strategies including early isolation of suspected cases, strict infection control measures in the hospital setting, meticulous contact tracing and quarantine, the outbreak was finally brought under control by July 2003. In addition, there were another two events of SARS in China between the end of December 2003 and January 2004 and from March to May 2004; both were readily controlled without significant patient spread.

    AIM: To evaluate the efficacy of intravenous glutamine on the patients with severe acute pancreatitis (SAP). METHODS: The Cochrane Library, PubMed, EMBASE, and EBM review databases were searched up to June 2012. Randomized controlled trials (RCTs) that compared non-glutamine nutrition with intravenous glutamine supplemented nutrition in patients with SAP were included. A method recommended by the Cochrane Collaboration was used to perform a meta-analysis of those RCTs. RESULTS: Four RCTs involving a total of 190 participants were included. Analysis of these RCTs revealed the presence of statistical homogeneity among them. Results showed that glutamine dipeptide has a positive effect in reducing the mortality rate (OR = 0.26, 95%CI: 0.09-0.73, P = 0.01), length of hospital stay (weighted mean difference = -4.85, 95%CI: 6.67--3.03, P < 0.001), and the rate of complications (OR = 0.41, 95%CI: 0.22-0.78, P = 0.006). No serious adverse effects were found. CONCLUSION: Current best evidence demonstrates that glutamine is effective for SAP. Further high quality trials are required and parameters of nutritional condition and hospital cost should be considered in future RCTs with sufficient size and rigorous design. PMID:24701410

    Objective: To compare the efficacy and safety of early, nasogastric enteral nutrition (EN) with total parenteral nutrition (TPN) in patients with predicted severe acute pancreatitis (SAP). Summary Background Data: In SAP, the magnitude of the inflammatory response as well as increased intestinal permeability correlates with outcome. Enteral feeding has been suggested superior to parenteral feeding due to a proposed beneficial effect on the gut barrier. Methods: Fifty patients who met the inclusion criteria were randomized to TPN or EN groups. The nutritional regimen was started within 24 hours from admission and EN was provided through a nasogastric tube. The observation period was 10 days. Intestinal permeability was measured by excretion of polyethylene glycol (PEG) and concentrations of antiendotoxin core antibodies (Endocab). Interleukins (IL)-6 IL-8, and C-reactive protein (CRP) were used as markers of the systemic inflammatory response. Morbidity and feasibility of the nutritional route were evaluated by the frequency of complications, gastrointestinal symptoms, and abdominal pain. Results: PEG, Endocab, CRP, IL-6, APACHE II score, severity according to the Atlanta classification (22 patients), and gastrointestinal symptoms or abdominal pain did not significantly differ between the groups. The incidence of hyperglycemia was significantly higher in TPN patients (21 of 26 vs. 7 of 23; P < 0.001). Total complications (25 vs. 52; P = 0.04) and pulmonary complications (10 vs. 21; P = 0.04) were significantly more frequent in EN patients, although complications were diagnosed dominantly within the first 3 days. Conclusion: In predicted SAP, nasogastric early EN was feasible and resulted in better control of blood glucose levels, although the overall early complication rate was higher in the EN group. No beneficial effects on intestinal permeability or the inflammatory response were seen by EN treatment. PMID:17122621

    This paper provides a review of a recently published series of studies that give a detailed and comprehensive documentation of the severe acute respiratory syndrome (SARS) epidemic in mainland China, which severely struck the country in the spring of 2003. The epidemic spanned a large geographical extent but clustered in two areas: first in Guangdong Province, and about 3 months later in Beijing with its surrounding areas. Reanalysis of all available epidemiological data resulted in a total of 5327 probable cases of SARS, of whom 343 died. The resulting case fatality ratio (CFR) of 6.4% was less than half of that in other SARS-affected countries or areas, and this difference could only partly be explained by younger age of patients and higher number of community acquired infections. Analysis of the impact of interventions demonstrated that strong political commitment and a centrally coordinated response was the most important factor to control SARS in mainland China, whereas the most stringent control measures were all initiated when the epidemic was already dying down. The long-term economic consequence of the epidemic was limited, much consumption was merely postponed, but for Beijing irrecoverable losses to the tourist sector were considerable. An important finding from a cohort study was that many former SARS patients currently suffer from avascular osteonecrosis, as a consequence of the treatment with corticosteroids during their infection. The SARS epidemic provided valuable information and lessons relevant in controlling outbreaks of newly emerging infectious diseases, and has led to fundamental reforms of the Chinese health system. In particular, a comprehensive nationwide internet-based disease reporting system was established. PMID:24470901

    Post-traumatic headache can occur after any traumatic brain injury, regardless of severity. Headache is consistently the most common symptom following concussion and occurs in over 90 % of athletes with sports-related concussion. Despite this prevalence, the complaint of headache after a possible concussive injury is often dismissed. Even when sports-related concussion is accurately diagnosed, many athletes fall victim to mismanagement of this associated symptom by clinicians who are not well-versed in headache treatment. Furthermore, benign headaches may also occur incidentally in the context of head trauma. This complex, and often non-specific, nature of headaches provides a significant challenge in return to play decision-making. Post-traumatic headaches are generally categorized according to primary headache disorders in an attempt to guide treatment; however, there is minimal medical literature on headache management in the concussed athlete. There is clearly a continued need for prospective studies of existing treatments and new approaches. PMID:27184059

    Hijab (headscarf) headache is well known among wearers and is a common topic of discussion. It has never previously been reported in the medical literature. Five women described bilateral headache either prompted by or worsened by donning the hijab, or headscarf. The headache always resolved soon after removal of the headscarf. Hijab headache may also be alleviated by minimal modifications in style while allowing women to maintain their moral conviction. It likely represents an extracranial etiology of headache, and recognition may prevent unnecessary evaluation and suffering in hijab wearers. PMID:25711501

    Objective The objective of this study was to explore the conditions necessary to assign causal status to headache triggers. Background The term “headache trigger” is commonly used to label any stimulus that is assumed to cause headaches. However, the assumptions required for determining if a given stimulus in fact has a causal-type relationship in eliciting headaches have not been explicated. Methods A synthesis and application of Rubin’s Causal Model is applied to the context of headache causes. From this application the conditions necessary to infer that one event (trigger) causes another (headache) are outlined using basic assumptions and examples from relevant literature. Results Although many conditions must be satisfied for a causal attribution, three basic assumptions are identified for determining causality in headache triggers: 1) constancy of the sufferer; 2) constancy of the trigger effect; and 3) constancy of the trigger presentation. A valid evaluation of a potential trigger’s effect can only be undertaken once these three basic assumptions are satisfied during formal or informal studies of headache triggers. Conclusions Evaluating these assumptions is extremely difficult or infeasible in clinical practice, and satisfying them during natural experimentation is unlikely. Researchers, practitioners, and headache sufferers are encouraged to avoid natural experimentation to determine the causal effects of headache triggers. Instead, formal experimental designs or retrospective diary studies using advanced statistical modeling techniques provide the best approaches to satisfy the required assumptions and inform causal statements about headache triggers.

    Fasting is frequently mentioned by patients and in textbooks as a trigger for headache. In this study, we attempted to define the role of fasting as a possible precipitator of headache. Headache history was documented in 370 hospital employees (60% female) before and immediately after a 25-hour fast for the 1993 Day of Atonement (Yom Kippur). The population included 211 who fasted; 39% of fasters developed headache, compared with only 7% of nonfasters (p < 0.000001). Headache was usually of a nonpulsating quality, mild to moderate in intensity, and bilateral and frontal in location. Subjects with a history of headache were more likely to develop fasting-induced headache than were those without such history (66% versus 29%, p < 0.000002). The number of headache sufferers increased in direct relation to the duration of the fast. Caffeine and nicotine withdrawal and oversleeping did not appear to have an influence on headache development. We conclude that fasting is a strong headache precipitator, especially among chronic headache sufferers. It is usually nonpulsating and nonlateralized. PMID:7501139

    In the present study we investigated the pattern and efficacy of respiratory autoresuscitation in spontaneously breathing adult male rats across three separate anesthetic backgrounds. Each animal was administered one of three injectable anesthetics to achieve a surgical plane of anesthesia: ketamine-xylazine (KET, n=10), pentobarbital (PEN, n=10), or urethane (URE, n=10). Animals were tracheostomized and equipped with a femoral artery catheter to record airflow and arterial pressures. In response to a bout of breathing anoxic air, none of the 10 URE animals were able to mount a successful autoresuscitation response. In contrast, all KET and PEN animals survived all four consecutive anoxic exposures, restoring eupneic breathing in all cases. Moreover, only 4/10 URE animals expressed gasping breaths following the onset of respiratory arrest, and these were temporally delayed (p<0.001) and much smaller in volume (P≤0.012) compared to KET and PEN animals. URE animals showed no clear aberrations in their cardiovascular responses to anoxia, with the exception of lower arterial pulse pressures compared to either KET or PEN animals at specific points following RA. Ketamine-xylazine and pentobarbital anesthesia can be reliably and effectively used to create models for the study of autoresuscitation in adult rats. In contrast, urethane causes catastrophic failure of respiratory autoresuscitation, by delaying or outright preventing the elaboration of gasping breaths following anoxia-induced respiratory arrest. The neuronal and synaptic alterations accompanying urethane anesthesia may therefore provide a means of understanding potential pathological alterations in rhythm generation that can predispose the respiratory control system to failed autoresuscitation following an episode of acute severe hypoxemia.

  3. Sphenopalatine Ganglion Stimulation in Neurovascular Headaches.

    PubMed

    2015-01-01

    The interest for the sphenopalatine ganglion (SPG) in neurovascular headaches dates back to 1908 when Sluder presented his work on the role of the SPG in 'nasal headaches', which are now part of the trigeminal autonomic cephalalgias and cluster headache (ICHD-III-beta). Since then various interventions with blocking or lesional properties have targeted the SPG (transnasal injection of lidocaine and other agents, alcohol or steroid injections, radiofrequency lesions, or even ganglionectomy); success rates vary, but benefit is usually transient. Here we briefly review some anatomophysiological characteristics of the SPG and hypotheses about its pathophysiological role in neurovascular headaches before describing recent therapeutic results obtained with electrical stimulation of the SPG. Based on results of a prospective randomized controlled study, SPG stimulation appears to be an effective treatment option for patients with chronic cluster headaches; efficacy data indicate that acute electrical stimulation of the SPG provides significant attack pain relief and in many cases pain freedom compared to sham stimulation. Moreover, in some patients SPG stimulation has been associated with a significant and clinically meaningful reduction in cluster headache attack frequency; this preventive effect of SPG stimulation warrants further investigation. For migraine attacks, the outcome of a proof-of-concept study using a temporary electrode implanted in the pterygopalatine fossa was less encouraging; however, an ongoing multicenter trial is evaluating the efficacy of long-term SPG stimulation against sham stimulation for acute and preventive treatment in patients with frequent migraine.

    Objective Severe acute malnutrition (SAM) is a major cause of mortality in children under 5 years and is associated with hepatic steatosis. Bile acids are synthesized in the liver and participate in dietary fat digestion, regulation of energy expenditure, and immune responses. The aim of this work was to investigate whether SAM is associated with clinically relevant changes in bile acid homeostasis. Design An initial discovery cohort with 5 healthy controls and 22 SAM-patients was used to identify altered bile acid homeostasis. A follow up cohort of 40 SAM-patients were then studied on admission and 3 days after clinical stabilization to assess recovery in bile acid metabolism. Recruited children were 6–60 months old and admitted for SAM in Malawi. Clinical characteristics, feces and blood were collected on admission and prior to discharge. Bile acids, 7α-hydroxy-4-cholesten-3-one (C4) and FGF-19 were quantified. Results On admission, total serum bile acids were higher in children with SAM than in healthy controls and glycine-conjugates accounted for most of this accumulation with median and interquartile range (IQR) of 24.6 μmol/L [8.6–47.7] compared to 1.9 μmol/L [1.7–3.3] (p = 0.01) in controls. Total serum bile acid concentrations did not decrease prior to discharge. On admission, fecal conjugated bile acids were lower and secondary bile acids higher at admission compared to pre- discharge, suggesting increased bacterial conversion. FGF19 (Fibroblast growth factor 19), a marker of intestinal bile acid signaling, was higher on admission and was associated with decreased C4 concentrations as a marker of bile acid synthesis. Upon recovery, fecal calprotectin, a marker of intestinal inflammation, was lower. Conclusion SAM is associated with increased serum bile acid levels despite reduced synthesis rates. In SAM, there tends to be increased deconjugation of bile acids and conversion from primary to secondary bile acids, which may contribute to the

    Severe acute respiratory syndrome (SARS) is a recently emerged infectious disease with significant morbidity and mortality. An epidemic in 2003 affected 8,098 patients in 29 countries with 774 deaths. The aetiological agent is a new coronavirus spread by droplet transmission. Clinical and general laboratory manifestations included fever, chills, rigor, myalgia, malaise, diarrhoea, cough, dyspnoea, pneumonia, lymphopenia, neutrophilia, thrombocytopenia, and elevated serum lactate dehydrogenase (LD), alanine aminotransferase (ALT) and creatine kinase (CK) activities. Treatment has been empirical; initial potent antibiotic cover, followed by simultaneous ribavirin and corticosteroids, with or without pulse high-dose methylprednisolone, have been used. The postulated disease progression comprises (1) active viral infection, (2) hyperactive immune response, and (3) recovery or pulmonary destruction and death. We investigated serum LD isoenzymes and blood lymphocyte subsets of SARS patients, and found LD1 activity as the best biochemical prognostic indicator for death, while CD3+, CD4+, CD8+ and natural killer cell counts were promising predictors for intensive care unit (ICU) admission. Plasma cytokine and chemokine profiles showed markedly elevated Th1 cytokine interferon (IFN)-gamma, inflammatory cytokines interleukin (IL)-1beta, IL-6 and IL-12, neutrophil chemokine IL-8, monocyte chemoattractant protein-1 (MCP-1), and Th1 chemokine IFN-gamma-inducible protein-10 (IP-10) for at least two weeks after disease onset, but there was no significant elevation of inflammatory cytokine tumor necrosis factor (TNF)-alpha and anti-inflammatory cytokine IL-10. Corticosteroid reduced IL-8, MCP-1 and IP-10 concentrations from 5-8 days after treatment. Measurement of biochemical markers of bone metabolism demonstrated significant but transient increase in bone resorption from Day 28-44 after onset of fever, when pulse steroid was most frequently given.

    Acute respiratory distress syndrome (ARDS) is defined by acute diffuse inflammatory lung injury invoked by a variety of systemic or pulmonary insults. Despite medical progress in management, mortality remains 27% to 45%. Patients with ARDS should be managed with low tidal volume ventilation. Permissive hypercapnea is well tolerated. Conservative fluid strategy can reduce ventilator and hospital days in patients without shock. Prone positioning and neuromuscular blockers reduce mortality in some patients. Early management of ARDS is relevant to emergency medicine. Identifying ARDS patients who should be transferred to an extracorporeal membrane oxygenation center is an important task for emergency providers. PMID:26614238

    Neuromodulation is being applied increasingly for the treatment of drug resistant headache. Although these techniques are often considered high-tech, electrotherapy for headache has a long history; electric fish have been used for headache treatment since the first century CE. During the eighteenth and nineteenth century, static electricity was a treatment for a wide variety of neuropsychiatric disorders including headache. The efficacy of electrotherapy, however, has been disputed continuously, since opponents were of the opinion that the positive results could be attributed to suggestion. At the beginning of the twentieth century, the electric treatment of headache gradually disappeared. In recent years, there has been a resurgence in the use of electrotherapy, along with the efficacy debate. With this historical review we wish to emphasize the importance of placebo-controlled studies, not only in terms of electrotherapy of headache, but also for the evaluation of neuromodulation for other disorders.

    Ten percent of 362 headache sufferers reported sexual arousal during migraine attack. Clinical investigations on sexuality in 16 headache sufferers, according to some studies showing correlations between idiopathic headache and sexual behavior, were performed. Patients responding by questionnaire listed each sexual experience, headache attack, and number of sleeping hours every day for 1 month. In both men and women, the number of coiti, erotic dreams, and sleeping hours were similar in headache sufferers and controls, while the frequency of masturbation was significantly reduced in the former. Sexual excitement and fantasies appeared more often in female headache sufferers than in controls, while the opposite occurred in the male group. Among the clinical analogies between the crises of migraine and morphine abstinence, sexual arousal may be included. PMID:7054999

    A weekly periodicity in the occurrence of headache was found in 53 patients with migraine and in 20 with tension headache during an observation period of four weeks. In the migraine group the frequency was highest on Thursday and on Saturday and lowest on Sunday Monday, and in patients with tension headache it was lowest on Sunday Tuesday and highest on Friday. During the observation period several climatic factors were recorded. After correction for the weekly periodicity a highly significant correlation was found in the migraine group between headache frequency, on the one hand, and atmospheric pressure and outdoor temperature recorded 1 3 days later, on the other.

    The present part II review highlights pharmacokinetic drug-drug interactions (excluding those of minor severity) of medications used in prophylactic treatment of the main primary headaches (migraine, tension-type and cluster headache). The principles of pharmacokinetics and metabolism, and the interactions of medications for acute treatment are examined in part I. The overall goal of this series of two reviews is to increase the awareness of physicians, primary care providers and specialists regarding pharmacokinetic drug-drug interactions (DDIs) of headache medications. The aim of prophylactic treatment is to reduce the frequency of headache attacks using beta-blockers, calcium-channel blockers, antidepressants, antiepileptics, lithium, serotonin antagonists, corticosteroids and muscle relaxants, which must be taken daily for long periods. During treatment the patient often continues to take symptomatic drugs for the attack, and may need other medications for associated or new-onset illnesses. DDIs can, therefore, occur. As a whole, DDIs of clinical relevance concerning prophylactic drugs are a limited number. Their effects can be prevented by starting the treatment with low dosages, which should be gradually increased depending on response and side effects, while frequently monitoring the patient and plasma levels of other possible coadministered drugs with a narrow therapeutic range. Most headache medications are substrates of CYP2D6 (e.g., beta-blockers, antidepressants) or CYP3A4 (e.g., calcium-channel blockers, selective serotonin re-uptake inhibitors, corticosteroids). The inducers and, especially, the inhibitors of these isoenzymes should be carefully coadministered. PMID:17125412

  14. Stabbing headache in an 8-year-old girl: primary or drug induced headache?

    PubMed

    The occurrence of stabbing headaches in children requires a thorough diagnostic approach that excludes secondary headaches. The organic background should be taken into consideration when alarming symptoms occur, such as a purely 1-sided location, a change in the character of the headache, or possibly a link to physical activity. The current study describes the case of an 8-year-old girl who suffered short-lasting stabbing headache attacks. The headaches with increasing intensity and frequency started 1 month before her hospitalization and were usually preceded by physical activity (dancing, running). The pain, which was located in the right supraorbital region, lasted 1 second and occurred several times during the day. No associated symptoms were observed. In addition, the girl suffered from allergic rhinitis and was on antiallergic treatment (levocetirizine, fluticasone nasal spray). On admission she was in good general condition, and a pediatric and neurologic examination revealed no abnormalities. Her brain MRI was normal. The initial diagnosis was that the patient was suffering from primary stabbing headaches. However, during a follow-up visit 4 months later, a relationship was observed between the cessation of the headache attacks and the discontinuation of an antihistaminic drug. Six months later, the girl remained headache free. In cases involving differential diagnoses of stabbing headaches, it is important to consider the adverse reactions of the drugs used. PMID:24664098

    Granulomatous interstitial nephritis (GIN) is an uncommon cause of renal failure, which may be caused by drugs. Levetiracetam is an increasingly used anti-epileptic medication that is not known to cause renal toxicity in adults. To our knowledge, levetiracetam has not previously been reported as a cause of GIN. We report the case of a 69-year-old woman who developed haemodialysis-requiring acute renal failure after commencement of treatment with levetiracetam, which was shown to be GIN by renal biopsy. She made a complete recovery with cessation of levetiracetam and treatment with steroids. PMID:26069773

  17. Headache yesterday in Europe

    PubMed Central

    2014-01-01

    Background Surveys enquiring about burden of headache over a prior period of time (eg, 3 months) are subject to recall bias. To eliminate this as far as possible, we focused on presence and impact of headache on the preceding day (“headache yesterday”). Methods Adults (18-65 years) were surveyed from the general populations of Germany, Italy, Lithuania, Luxembourg and the Netherlands, from a work-force population in Spain and from mostly non-headache patient populations of Austria, France and UK. A study of non-responders in some countries allowed detection of potential participation bias where initial participation rates were low. Results Participation rates varied between 11% and 59% (mean 27%). Non-responder studies suggested that, because of participation bias, headache prevalence might be overestimated in initial responders by up to 2% (absolute). Across all countries, 1,422 of 8,271 participants (15-17%, depending on correction for participation bias) had headache yesterday lasting on average for 6 hours. It was bad or very bad in 56% of cases and caused absence from work or school in 6%. Among those who worked despite headache, 20% reported productivity reduced by >50%. Social activities were lost by 24%. Women (21%) were more likely than men (12%) to have headache yesterday, but impact was similar in the two genders. Conclusions With recall biases avoided, our findings indicate that headache costs at least 0.7% of working capacity in Europe. This calculation takes into account that most of those who missed work could make up for this later, which, however, means that leisure and social activities are even more influenced by headache.

  18. Fasting headache, weight loss, and dehydration.

    1999-03-01

    Recently, we showed that fasting is a strong headache precipitator unrelated to coffee, tea, or smoking withdrawal or to oversleeping. In the current study, we evaluated the role of dehydration as a possible precipitator of fasting headache. The effects of a 25-hour fast of the Jewish Yom Kippur (Day of Atonement) were studied in women who participated in our previous Yom Kippur study. We asked the subjects to weigh themselves at the beginning and at the end of the Yom Kippur fast, assuming that the weight loss would largely reflect dehydration. In all but 1 of the 56 participants, the fast resulted in weight loss but only 28 (50%) reported headache. The average weight loss was 1.4 +/- 0.8 kg in those who developed headache and 1.2 +/- 0.5 kg in those who did not. This small difference was not statistically significant. We conclude that dehydration, as reflected by acute weight loss, is an unlikely cause of headache during a single day of fasting. The mechanism of fasting headache remains unclear. PMID:15613218

    An epidemiological survey on headache was performed in the Republic of San Marino, which is the smallest independent State in the world, located near the Adriatic Coast, within Italy. Among a random sample of 1500 inhabitants over 7 years of age the frequency of headache, severe headache and migraine in the previous year was 35.3%, 12.2%, 9.3% respectively for men, and 46.2%, 20.6%, 18% for women. The most common factors reported to provoke headache were emotional stress, physical strain, lack of sleep, particular foods or drinks and for women menstruation. Migraine patients differed from people without headache in that they had a higher consumption of coffee, more frequently reported bad sleep, allergic disease and previous appendectomy. Furthermore, migraine patients and severe headache sufferers had a higher diastolic blood pressure than non headache subjects. PMID:3258357

  20. Headache prevalence following recovery from TTP and aHUS.

    2015-09-01

    Thrombotic thrombocytopenia purpura (TTP) and atypical hemolytic uremic syndromes (aHUS) are distinct clinical disorders characterized by hemolytic anemia, thrombocytopenia, microthrombi, and end organ damage. TTP is characterized by a low ADAMTS13 activity level at diagnosis of <10 % ADAMTS13 activity, while aHUS is characterized as having >10 % ADAMTS13 activity. Despite clinical remission, survivors of thrombotic microangiopathy suffer significant comorbidity and decreased quality of life (QOL) than their healthy counterparts. The reason for this is unclear. Is it a lingering effect from their initial acute episode or ongoing subclinical injury/inflammation despite clinical remission? Common clinical complaints validated in practice include increased depression, deficits in memory, concentration, mood, and mental endurance. We suspect headaches may be an important clinical tool toward understanding patient morbidity and decreased QOL. To date, no studies report headache frequency or severity in this population. To answer this question, adult patients >3 months since their last acute episode of TTP or aHUS were approached to take a Headache Impact Test (HIT-6) survey. Between June 1, 2013 and May 30, 2014, 31 patients in remission (21 patients with prior TTP and 10 patients with prior aHUS) completed the HIT-6 survey. The survey scores were then compared to the HIT-6 normative population data established by Qualitymetric incorporated. Overall, TTP patients had a significantly higher average HIT-6 score of 59.9 compared to an average HIT-6 score of 51 seen in sex-matched controls (SD 9.6, p value 0.002). No significant difference was seen in the HIT-6 scores of aHUS patients. Of TTP patients studied, approximately 57 % (12/21) had three or more episodes and were >24 months since the last episode. The average time since last acute episode in TTP patients was 37.5 months. There was no significant correlation between TTP survivor HIT-6 scores and the number of

    2004-10-01

    The subcommittee of the International Headache Society for headache classification (ICHD-II) has recently recognised that secondary headaches may occur in patients affected by inflammatory diseases (ID) of the central nervous system (CNS), classifying them among the headaches attributed to non-vascular intracranial disorders. The aim of the study was to verify the association between headache and inflammatory non-infectious diseases of the CNS, by a review of the literature data on the topic, integrated by personal cases and data. Secondary headaches may occur in four main disorders: neurosarcoidosis (sec 7.3.1), aseptic (non-infectious) meningitis (7.3.2), other non-infectious ID (7.3.3) and lymphocytic hypophysitis (7.3.4). Headache and/or primary headaches are frequently reported in patients with neurosarcoidosis (30%), Behcet's syndrome (BS) (55%) and acute disseminated encephalomyelitis (45-58%). Recent data show a high incidence of headache also in multiple sclerosis (MS) (58%) (not mentioned in ICHD-II). The association between headache and inflammatory dysimmune diseases of the CNS, in particular BS and MS, might suggest a pathogenetic relationship. PMID:15549526

  2. Medication-overuse headache: a review

    2014-01-01

    Medication-overuse headache (MOH) is a worldwide health problem with a prevalence of 1%–2%. It is a severe form of headache where the patients often have a long history of headache and of unsuccessful treatments. MOH is characterized by chronic headache and overuse of different headache medications. Through the years, withdrawal of the overused medication has been recognized as the treatment of choice. However, currently, there is no clear consensus regarding the optimal strategy for management of MOH. Treatment approaches are based on expert opinion rather than scientific evidence. This review focuses on aspects of epidemiology, diagnosis, pathogenesis, prevention, and treatment of MOH. We suggest that information and education about the risk of MOH is important since the condition is preventable. Most patients experience reduction of headache days and intensity after successful treatment. The first step in the treatment of MOH should be carried out in primary care and focus primarily on withdrawal, leaving prophylactic medication to those who do not manage primary detoxification. For most patients, a general practitioner can perform the follow-up after detoxification. More complicated cases should be referred to neurologists and headache clinics. Patients suffering with MOH have much to gain by an earlier treatment-focused approach, since the condition is both preventable and treatable. PMID:25061336

  4. Clinical aspects of perimenstrual headaches.

    2009-02-01

    Menstrual migraine (MM) is either pure, if attacks are limited solely during the perimenstrual window (PMW), or menstrually related (MRM), if two of three PMWs are associated with attacks with additional migraine events outside the PMW. Acute migraine specific therapy is equally effective in MM and non-MM. Although the International Classification of Headache Disorders-II classifies MM without aura, data suggest this needs revision. The studies on extended-cycle oral contraceptives suggest benefits for headache-prone individuals. Triptan mini-prophylaxis outcomes are positive, but a conclusion of "minimal net benefit compared to placebo" is not entirely unwarranted. In a 2008 evidence-based review, grade B recommendations exist for sumatriptan (50 and 100 mg), mefenamic acid (500 mg), and riza-triptan (10 mg) for the acute treatment of MRM. For the preventive mini-prophylactic treatment of MRM, grade B recommendations are provided for transcutaneous estrogen (1.5 mg), frovatriptan (2.5 mg twice daily), and naratriptan (1 mg twice daily).

    Previous studies suggest that 5 days of prophylactic ginkgo decreases the incidence of acute mountain sickness (AMS) during gradual ascent. This trial was designed to determine if ginkgo is an effective prophylactic agent if begun 1 day prior to rapid ascent. In this double-blind, randomized, placebo-controlled trial, 26 participants residing at sea level received ginkgo (60 mg TID) or placebo starting 24 h before ascending Mauna Kea, Hawaii. Subjects were transported from sea level to the summit (4205 m) over 3 hours, including 1 hour at 2835 m. The Lake Louise Self-report Questionnaire constituted the primary outcome measure at baseline, 2835 m, and after 4 h at 4205 m. AMS was defined as a Lake Louise Self-report Score (LLSR) >/= 3 with headache. Subjects who developed severe AMS were promptly transported to lower altitude for the remainder of the study. The ginkgo (n = 12) and placebo (n = 14) groups were well matched (58% vs. 50% female; median age 28 yr, range 22-53 vs. 33 yr, range 21-53; 58% vs. 57% Caucasian). Two (17%) subjects on ginkgo and nine (64%) on placebo developed severe AMS and required descent for their safety (p = 0.021); all recovered without sequelae. Median LLSR at 4205 m was significantly lower for ginkgo versus placebo (4, range 1-8 vs. 5, range 2-9, p = 0.03). Ginkgo use did not reach statistical significance for lowering incidence of AMS compared with placebo (ginkgo 7/12, 58.3% vs. placebo 13/14, 92.9%, p = 0.07). Twenty-one of 26 (81%) subjects developed AMS overall. This is the first study to demonstrate that 1 day of pretreatment with ginkgo 60 mg TID may significantly reduce the severity of AMS prior to rapid ascent from sea level to 4205 m. PMID:12006162

    A 50-year-old woman had a gradual onset of chronic headache located in the right temporal region and a burning sensation in the root of the tongue which over a year evolved into chronic cluster headache with a milder chronic headache in-between the severe cluster headache attacks. A cerebral magnetic resonance imaging (MRI) showed vascular compression of the trigeminal nerve root on the pain side. Neurosurgery microvascular decompression relieved the patient's chronic cluster headache, the chronic intermittent headache and the burning tongue sensation. The effect was persistent at a 1 year follow-up. Patients with atypical symptoms of cluster headache should be examined with cerebral MRI angiography of arteries and veins to exclude symptomatic causes. PMID:20384588

    2007-01-01

    We reviewed our series of consecutive cases of severe pancreatitis observed from 2002 to 2004, in order to verify how our actual therapeutic strategy improved prognosis. Seventeen patients with diagnosis of severe pancreatitis (SP) were admitted. On presumption of SP we inserted a naso-jejunal self-propelling feeding tube (SPT) in all but one patients, and an early enteral nutrition ( EEN ) was started. Severity of pancreatitis has been scored by APACHE II (> 8), IMRIE (> or = 3), and Balthazar Computed Tomography findings (> 30% necrosis). We always used a polymeric diet added with glutamine and fibres at initial rate of 20-30 ml/h until achievement of a full regimen of EEN, based on Harris-Benedict formula but no more than 30 kcal/kg/day. Only one patient has been submitted to surgical removal of infected necrosis. A patient died (5.8%) by dis-metabolic and septic state. From our experience we can state EEN is safe and useful to determine a favourable outcome on this dismal pathology, preserving the patient from infection, without significative alterations of nutritional index.

    Acute pulmonary toxicity associated with brentuximab appears to be a rare but serious adverse effect that can be potentially fatal. We report the case of a twenty-nine-year-old female with Hodgkin's lymphoma who was treated with brentuximab and later presented with severe acute pulmonary toxicity; she improved after the discontinuation of brentuximab and administration of antibiotics and glucocorticoid therapy. Currently there is very little data in the literature in regard to the clinical manifestations and characteristics of patients taking brentuximab and the potential development of acute severe pulmonary toxicity, as well as the appropriate therapeutic approach, making this particular case of successful treatment and resolution unique.

    A 37-year-old man developed an ipsilateral headache which fulfilled the criteria for cluster headache after orbital extenteration because of a traumatic lesion of the bulb. The headache could be treated successfully by drugs usually applied in the therapy of cluster headache. Six similar cases of cluster headache after orbital exenteration could be identified in the literature suggesting that the eye itself is not necessarily part of the pathogenesis of cluster headache. We hypothesize that orbital exenteration can cause cluster headache by lesions of sympathetic structures. Possibly, these mechanisms are similar to those of sympathetic reflex dystrophy (Sudeck-Leriche syndrome) causing pain of the limbs. PMID:9350391

    Old headache medicines never die; they either fade away or come back in disguise. The disguise is often a new route of administration, which may work better, faster, more completely, with fewer adverse events, and/or have certain other advantages. The clinical aspects of 3 of the oldest headache medicines (ergotamine tartrate, dihydroergotamine, and methysergide) will be discussed here. Sumatriptan will then be discussed as the prototype of the newest category of acute care therapy (triptans) for migraine. It will be compared with the older medications, and the new forms being developed will be briefly discussed. Diclofenac potassium for oral solution will be mentioned as the newest drug approved for migraine by the Food and Drug Administration, and a possible alternative to triptans in patients with frequent headaches or those with contraindications to vasoconstrictors.

    Background. Migraines are one of the most commonly occurring ailments affecting the nervous system. The aim of this research paper was to evaluate the effect migraines have on the everyday functioning of women. Method. The study involved women with diagnosed migraine headaches (IHS-2004) undergoing treatment at a neurological clinic. In order to evaluate the influence of headaches on the everyday functioning of women, a MSQ v.2 questionnaire was used, whereas pain severity was assessed on a linear VAS scale. Results. Among the clinical factors, the most influential was the frequency of headaches. Headache duration was particularly significant for women below the age of 40. Pain severity cited at 8–10 pts on the VAS significantly disrupted and limited everyday functioning. On the emotional function subscale, the most influential factors were age, education, and the frequency of headaches. Conclusions. On account of headache frequency emerging as the most significant influencing factor, it is of the utmost importance to inform patients of the value of taking prophylactic measures. Central to this is the identification of factors that trigger the onset of migraines. This approach would greatly aid the individual in choosing the appropriate treatment, either pharmacological or others. PMID:25133238

    Many healthcare workers were infected while looking after the SARS patients on the medical wards in 2003. The high infectivity of the SARS coronavirus with peak viral load on day 10 of illness when patients were ill, overcrowding of the old medical wards with low air changes/hr (ACH), and aerosol-generating procedures while resuscitating the patients were the major factors. Procedures reported to present an increased risk of SARS transmission include tracheal intubation, non-invasive ventilation, tracheotomy and manual ventilation before intubation whereas oxygen therapy and bed distance <1 m were also implicated. Studies based on laser visualization technique with smoke particles as smokers in the human patient simulator has shown that oxygen therapy via Hudson mask and nasal cannula could disperse exhaled air of patients to 0.4 and 1 m respectively whereas jet nebulizer could disperse exhaled air >0.8 m from the patient. Bigger isolation rooms with 16 ACH are more effective than smaller isolation rooms with 12 ACH in removing exhaled air and preventing room contamination but at the expense of more noise and electricity consumption. Non-invasive ventilation via face masks and single circuit can disperse exhaled air from 0.4 to 1 m. Both higher inspiratory pressures and use of whisper swivel device (to facilitate carbon dioxide removal) could increase the exhaled air leakage and isolation room contamination during on-invasive ventilation. Addition of a viral-bacterial filter during manual ventilation by bagging may reduce the exhaled air leakage forward and yet increase the sideway leakage. N95 mask was more effective than surgical mask in preventing expelled air leakage during patient's coughing but there was still significant sideway leakage to 15 cm. Clinicians should be aware of air leakage from the various face masks and adopt strict infection control measures during resuscitation of patients with severe respiratory infections.

  17. Wine and headache.

    PubMed

    Jarisch, R; Wantke, F

    1996-05-01

    Headache can be induced by histamine in wine in patients suffering from histamine intolerance, a disease characterized by impaired histamine degradation based on reduced diamine oxidase activity or a lack of the enzyme. Diamine oxidase is localized in the jejunal mucosa and is the most important enzyme metabolising histamine. It is competitively inhibited by alcohol and numerous drugs. In preliminary investigations, assessment of diamine oxidase levels gave decreased activity (0.03 nKat/l) in patients with histamine intolerance compared to healthy controls (0.07 nKat/l). In pregnancy, diamine oxidase levels are known to be about 500-fold elevated, giving mean levels of 25.0 nKat/l. Other biogenic amines such as phenylethylamine or serotonin may be causative for wine/food-induced headache. In experimental models, headache has been induced by histamine infusion as well as red wine provocation. Histamine-induced headache is a vascular headache likely to be caused by nitric oxide which probably represents a key molecule in vascular headaches. A histamine-free diet is the treatment of choice for patients with histamine intolerance and chronic headache. To start treatment, an antihistamine (H1 blocker) for 14 days as well as a histamine-free diet for at least 4 weeks are recommended. Clinical improvement to the diet as well as in vitro tests for plasma histamine and diamine oxidase in the serum as well as vitamin B6 levels have to confirm the diagnosis. As supportive treatment, a vitamin B6 (pyridoxal phosphate) substitution appears useful in histamine-intolerant patients as pyridoxal phosphate seems to be crucial for diamine oxidase activity. Histamine intolerance, based on reduced diamine oxidase activity or a lack in the enzyme is causative for wine/food-induced chronic headache. According to the localization of diamine oxidase in the jejunal mucosa, histamine intolerance is primarily a disease of intestinal origin. A histamine-free diet is the treatment of choice in

    In 2012, a female wildlife biologist experienced fever, malaise, headache, generalized myalgia and arthralgia, neck stiffness, and a sore throat shortly after returning to the United States from a 6-week field expedition to South Sudan and Uganda. She was hospitalized, after which a maculopapular rash developed and became confluent. When the patient was discharged from the hospital on day 14, arthralgia and myalgia had improved, oropharynx ulcerations had healed, the rash had resolved without desquamation, and blood counts and hepatic enzyme levels were returning to reference levels. After several known suspect pathogens were ruled out as the cause of her illness, deep sequencing and metagenomics analysis revealed a novel paramyxovirus related to rubula-like viruses isolated from fruit bats.

    We report a 49-year-old man with alcoholic severe acute pancreatitis (SAP) complicated by drug-induced acute tubulointerstitial nephritis (DI-AIN). Oliguria persisted and became anuric again on day 17 despite improvement of pancreatitis. He presented rash, fever and eosinophilia from day 20. Renal biopsy was performed for dialysis-dependent acute kidney injury (AKI), DI-AIN was revealed, and prompt use of corticosteroids fully restored his renal function. This diagnosis might be missed because it is difficult to perform renal biopsy in such a clinical situation. If the patient's general condition allows, renal biopsy should be performed and reversible AKI must be distinguished from many cases of irreversible AKI complicated by SAP. This is the first report of biopsy-proven DI-AIN associated with SAP, suggesting the importance of biopsy for distinguishing DI-AIN in persisting AKI of SAP. PMID:23645698

    Migraine headaches afflict approximately 6% of men and 18% of women in the United States, and cost billions of dollars each year in lost productivity, absenteeism, and direct medical expendi tures. Despite its prevalence and the availability of therapeutic op tions, many patients do not seek treatment, and among those who do, a significant portion are misdiagnosed. Correct diagnosis can be made by identifying the historic and physical examination finding that distinguish primary headache disorders from secondary head ache disorders, as well as the key clinical features that distinguis migraine headaches from other types. Once diagnosis is made, im proper or inadequate management of headache pain, related symp toms such as nausea, and the possible aggravating side-effects of pharmacologic therapies represent further obstacles to effective ther apy. Dissatisfaction with migraine therapy on the basis of these factors is common. Among abortive therapy options there are de livery methods available which may avoid aggravating symptom such as nausea. Recommended pharmacologic agents include non steroidal anti-inflammatory drugs, intranasal butorphanol, ergota mine and its derivatives, and the triptans. Indications for prophylac tic in addition to abortive therapy include the occurrence o headaches that require abortive therapy more than twice a week, tha do not respond well to abortive therapy, and which are particularly severe. Research is ongoing in the pathophysiology of migraines evaluation of nonpharmacologic treatment modalities, assessment of new drug therapies, and validation of headache guidelines. PMID:15586597

  1. Access to care - an unmet need in headache management?

    PubMed Central

    2014-01-01

    Access to care for headache sufferers is not always simple. A survey conducted in a large number of members of lay associations point to the existence of multiple barriers to care for headache in several European countries. Patients usually discover the existence of specialized structures with a delay of several years after the onset of their headache. Furthermore, a relevant portion of them are not satisfied with the management of their disease, partly because of the poor efficacy of treatments and partly because of the difficulty to get in touch with the specialist. Headache disorders, and primary headaches in particular, represent an important issue in public health, because they are common, disabling and treatable. A joint effort is required from the relevant stakeholders (scientists, lay organizations, decision-makers, healthcare policymakers, and others) to improve the access to care for headache sufferers.

    This study reports two cases of acute severe Coxsackie virus B4 myocarditis in which the immediate clinical signs suggested the acute phase of myocardial infarction, apparently antero-lateral in the first case in a context of cardiogenic shock and infero-lateral in the second case, in the context of acute pulmonary edema. Both cases were characterized by the severity of the initial signs. Numerous other cases of acute Coxsackie virus B myocarditis, simulating myocardial infarction, have been reported in the literature and these contexts deserve to be recognized earlier as they call for specific treatment. The immediate outcome was favorable in both cases but required massive cardiological intensive care in the first patient. Long term follow-up was excellent. PMID:8396381

    Toxic epidermal necrolysis syndrome (TEN) is a rare severe cutaneous adverse drug reaction that involves skin and mucous membranes. We describe a case of TEN presenting with stage III acute kidney injury, rhabdomyolysis, and acute respiratory failure likely triggered by allopurinol for recently diagnosed gout. Prompt diagnosis, multidisciplinary management, including aggressive resuscitation, cardiorespiratory support, intravenous immunoglobulin therapy, and daily wound care resulted in a positive outcome despite a predicted mortality greater than 60%. Although allopurinol is a known triggering agent, TEN presenting with rhabdomyolysis and acute kidney injury is rare. PMID:24832386

    Headaches constitute one of the most frequent reason of consultation. Their causes are extremely varied. The first step consists in the analysis of the characteristics of the pain and the associated signs in order to distinguish primary and secondary headaches. Primary headaches, including migraines and tension-type headaches are the most frequent types and do not require imaging evaluation. Secondary headaches are related to an organic cause and require specific investigations. In case of suspected symptomatic or secondary headaches, brain imaging plays an important role in the etiologic work-up. The main purpose of imaging in an emergency setting is to diagnose a life-threatening disease. PMID:15545938

    Temporomandibular disorders (TMD) and primary headaches can be perpetual and debilitating musculoskeletal and neurological disorders. The presence of both can affect up to one-sixth of the population at any one time. Initially, TMDs were thought to be predominantly musculoskeletal disorders, and migraine was thought to be solely a cerebrovascular disorder. The further understanding of their pathophysiology has helped to clarify their clinical presentation. This article focuses on the role of the trigeminal system in associating TMD and migraine. By discussing recent descriptions of prevalence, diagnosis, and treatment of headache and TMD, we will further elucidate this relationship. PMID:27475510

    Sturge-Weber syndrome (SWS) is a rare congenital disorder characterized by a facial vascular nevus associated with an ipsilateral leptomeningeal angioma. Headache is a rare component of SWS and when it occurs it usually occurs as a migraine-like headache. We aimed to present a SWS patient with episodic tension type headache and to draw attention in different types of headaches that can be seen in SWS. A 21 year old female patient with the diagnosis of SWS was suffering from severe headaches. At her physical examination a facial nevus -occurred due to choroid angioma- was observed. On her neurological examination a mild asymmetry of upper extremities was visible. She had a 2 year history of frequent non-pulsating headaches. There was no nausea or aura like symptoms accompanying the headache. Headaches were lasting for hours. The pain was bilateral and pressing in quality. SWS are a very rare and challenging disease for both the patients and their families. Usually migraine type headache is seen in SWS but it should not be forgotten that more generalized headaches like tension type may also be seen. PMID:25400854

    The history of headache, as a common neurological complication, goes back to almost 9000 years ago. Many ancient civilizations present references to headaches and the coherent treatment strategies. Accordingly, several documents comprising headache complications embodying precise medical information stem from Traditional Persian Medicine (TPM) that can provide useful opportunities for more comprehensive treatment. We conducted a survey on headache through original important pharmacopeias and other important medical manuscripts of TPM which were written during 9th to 19th centuries and have derived all headache categories and herbal remedies. An extensive search of scientific data banks, such as Medline and Scopus, has also been exercised to find results relating to the anti-inflammatory, anti-nociceptive, and analgesic effects of denoted medicinal herbs. The concept of headache and treatments in TPM covers over 20 various types of headache and more than 160 different medicinal plants administered for oral, topical, and nasal application according to 1000 years of the subject documents. Nearly, 60% of remarked medicinal herbs have related anti-inflammatory or analgesic effects and some current headache types have similarities and conformities to those of traditional types. Beside historical approaches, there are many possible and available strategies that can lead to development of new and effective headache treatment from medicinal plants so that this study can provide beneficial information on clinical remedies based on centuries of experience in the field of headache which can stand as a new candidate for further investigations.

  11. Cluster headache management and beyond.

    PubMed

    Martelletti, Paolo

    2015-01-01

    The therapeutic management of cluster headache is based on a very stable triad of drugs. Acute treatment has, in subcutaneous sumatriptan, its gold standard if compared to pure oxygen or indomethacin. Preventative treatment is based on verapamil at high doses (≥ 360 mg) and is a gold standard if compared to lithium carbonate or topiramate. Transitional treatments, based on the short-term use of corticosteroids with either systemic or local administration (GON), can be useful for the suppression of most resistant cluster periods, but with a well-known carry-over phenomenon related to the length of the cluster period itself. The role of invasive or noninvasive neuromodulation approaches must still be determined on a large scale; therefore, its use is not recommended as of yet. Lifestyle changes, including alcohol avoidance during the active phase of the disease, sleep hygiene and use of vasodilation drugs, should be carefully considered and the patients should be fully informed.

  12. Reversible Cerebral Vasoconstriction Syndrome Without Typical Thunderclap Headache.

    Wolff, Valérie; Ducros, Anne

    2016-04-01

    Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by severe headache and diffuse segmental intracranial arterial constriction that resolve within three months. Stroke, which is the major complication of RCVS, can result in persistent neurological disability, and rarely causes death. Diagnosis of RCVS early in the clinical course might improve outcomes. Although recurrent thunderclap headache is the clinical hallmark of RCVS, the absence of such a pattern should not lead to discard the diagnosis. Our literature review shows that RCVS can also manifest as an unspecific headache, such as a single severe headache episode, a mild or a progressive headache. Moreover, a subset of patients with severe RCVS presents without any headache, but frequently with seizures, focal neurological deficits, confusion or coma, in the setting of stroke or posterior reversible encephalopathy syndrome. These patients may be aphasic or in comatose state, explaining their inability to give their own medical history. They may have forgotten the headache they had a few days before more dramatic symptoms, or may have a variant of the classical RCVS. By consequence, an RCVS should be suspected in patients with any unusual headache, whether thunderclap or not, and in patients with cryptogenic stroke or convexity subarachnoid hemorrhage, whether the patient also has headache or not. Diagnosis in such cases relies on the demonstration of reversible multifocal intracranial arterial stenosis and the exclusion of other causes. PMID:27016378

    Background Acute pancreatitis is a common disease with wide clinical variation and its incidence is increasing. Acute pancreatitis may vary in severity, from mild self-limiting pancreatic inflammation to pancreatic necrosis with life-threatening sequelae. Severity of acute pancreatitis is linked to the presence of systemic organ dysfunctions and/or necrotizing pancreatitis. Aim and objectives The present study was aimed to assess the clinical profile of acute pancreatitis and to assess the efficacy of various severity indices in predicting the outcome of patients. Methodology This was a prospective study done in Sri Ramachandra Medical College and Hospital from April 2012–September 2014. All patients with a diagnosis of acute pancreatitis were included in this study. Along with routine lab parameters, serum amylase, lipase, lipid profile, calcium, CRP, LDH, CT abdomen, CXR and 2D Echo was done for all patients. Results A total of 110 patients were analysed. 50 patients required Intensive care, among them 9 patients (18%) died. 20 patients (18.2%) had MODS, 15 patients (13.6%) had pleural effusion, 9 patients (8.2%) had pseudocyst, 2 patients(1.8%) had hypotension, 2 patients(1.8%) had ARDS and 2 patients(1.8%) had DKA. In relation to various severity indices, high score of CRP, LDH and CT severity index was associated with increased morbidity and mortality. 15 patients (13.6%) underwent open necrosectomy surgery, 3 patients (2.7%) underwent laparoscopic necrosectomy and 7 patients (6.4%) were tried step up approach but could not avoid surgery. Step up approach and surgery did not have a significant reduction in the mortality. Conclusion Initial assessment of severity by CRP, LDH and lipase could be reliable indicators of outcome in acute pancreatitis PMID:26715920

    Macrophages are crucially involved in the pathophysiology of acute pancreatitis. Soluble CD163 (sCD163) is specifically released from macrophages and systemic levels are increased in inflammatory diseases. Here, sCD163 was measured in serum of 50 patients with acute pancreatitis to find out possible associations with disease activity. Admission levels of systemic sCD163 were nearly three-fold higher in patients with acute pancreatitis compared to controls. In patients sCD163 did not correlate with C-reactive protein and leukocyte count as established markers of inflammation. Levels were not associated with disease severity assessed by the Schroeder score, Balthazar score, Acute Physiology, Age, and Chronic Health Evaluation (Apache) II score and peripancreatic necrosis score. Soluble CD163 was not related to complications of acute pancreatitis. These data show that serum sCD163 is increased in acute pancreatitis indicating activation of macrophages but is not associated with disease severity and outcome. PMID:26209500

  15. Acupuncture for episodic cluster headache: a trigeminal approach.

    2016-02-01

    Following evidence that acupuncture is clinically feasible and cost-effective in the treatment of headache, the UK National Institute for Health and Care Excellence recommends acupuncture as prophylactic treatment for migraine and tension headache. There has thus been expectation that other forms of headache should benefit also. Unfortunately, acupuncture has not generally been successful for cluster headache. This may be due to acupuncturists approaching the problem as one of severe migraine. In fact, cluster headache is classed as a trigeminal autonomic cephalgia. In this case report, episodic cluster headache is treated in the same way as has been shown effective for trigeminal neuralgia. Acupuncture is applied to the contralateral side at points appropriate for stimulating branches of the trigeminal nerve. Thus, ST2 is used for the infraorbital nerve, BL2 and Yuyao for the supratrochlear and supraorbital nerves, and Taiyang for the temporal branch of the zygomatic nerve. PMID:26846705

    The goal of mechanical ventilation for patients with acute severe asthma is to ensure adequate oxygenation, ventilation, and gas exchange while simultaneously preventing hyperinflation, auto-positive end expiratory pressure, and subsequent barotrauma. Though existing evidence on the topic is relatively scarce, the application of current knowledge may guide our practice and prevent iatrogenic complications. To that end, this article describes selected ventilatory management strategies for the patient with acute severe asthma, such as the limitation of tidal volume size and respiratory rate, selection of specific inspiratory and expiratory ratios, the use of positive end expiratory pressure, and the application of helium-oxygen mixtures.

    2004-12-15

    The term "chronic daily headache" (CDH) describes a variety of headache types, of which chronic migraine is the most common. Daily headaches often are disabling and may be challenging to diagnose and treat. Medication overuse, or drug rebound headache, is the most treatable cause of refractory daily headache. A pathologic underlying cause should be considered in patients with recent-onset daily headache, a change from a previous headache pattern, or associated neurologic or systemic symptoms. Treatment of CDH focuses on reduction of headache triggers and use of preventive medication, most commonly anti-depressants, antiepileptic drugs, and beta blockers. Medication overuse must be treated with discontinuation of symptomatic medicines, a transitional therapy, and long-term prophylaxis. Anxiety and depression are common in patients with CDH and should be identified and treated. Although the condition is challenging, appropriate treatment of patients with CDH can bring about significant improvement in the patient's quality-of-life. PMID:15617293

    A total of 75 people residing in the metropolitan Boston area who had frequently recurring headaches kept a headache diary for one month beginning March 1975. Data were also collected about barometric pressure during this time. We found that the probability of headache severity on any day was independent of the effects of time. An inference of this, supported by other findings in this study, is that headache occurrence is minimally affected by time-related phenomena such as barometric pressure readings or changes..

    Despite being an excruciating headache, little is known about the burden of cluster headache (CH) regarding its various subtypes. In a multicentre, prospective study, patients with chronic CH (n = 27), with episodic CH in the active (n = 26) and outside the active period (n = 22), migraine patients (n = 24) and healthy controls (n = 31) were included. Epidemiological data, the German version of the Headache Disability Inventory (HDI) and a screening for psychiatric complaints were applied. About 25% of chronic CH patients in our study received invalidity allowance due to CH. HDI scores (total and subscales emotion and function) indicated a severe headache-specific disability (one-way ANOVA: P < 0.01). Patients with chronic and active episodic CH were significantly more affected than patients with inactive CH and migraine. Healthy volunteers were significantly less affected than all headache patients. Symptoms suggestive of psychiatric co-morbidity were found predominantly in chronic CH: depressive symptoms (56%), signs of agoraphobia (33%) and suicidal tendencies (25%) were frequently reported. Patients with chronic and active episodic CH were severely impaired in non-economic and economic domains such as disability, working life and psychiatric complaints. Remarkably, psychiatric co-morbidity was highest in chronic CH. Thus, especially chronic CH warrants special medical and further supportive care. PMID:21123629

    Background: Malnutrition represents one of the most severe health problems in India. Free radicals play an important role in immunological response, which induces the oxidative surplus in severe acute malnutrition. Severe dietary deficiency of nutrients leads to increased oxidative stress in cellular compartments. Aim: The goal of this study was to inspect impact of oxidative stress in the form of serum malondialdehyde as product of lipid peroxidation, vitamin E, zinc and erythrocyte superoxide dismutase in patients with severe acute malnutrition. Material and Methods: Sixty severe acute malnutrition patients were studied before and after supplementation of antioxidants for one month, and their status were compared with those of 60 age and sex matched healthy controls. The level of serum MDA was analyzed by the Kei Satoh method, serum vitamin E concentration was measured by Baker and Frank Method, serum zinc was measured by using Atomic Absorption Spectrophotometer (AAS) and erythrocyte superoxide dismutase was measured by Kajari Das Method. Results: Significantly increased levels of serum malondialdehyde (p<0.001) were found in the patients as compared to those in controls, and significant depletions were found in the levels of serum vitamin E, zinc and erythrocyte superoxide dismutase in patients with severe acute malnutrition as compared to those in controls. After supplementation of antioxidants for one month, the levels of malondialdehyde were found to be decreased significantly (p<0.001) and zinc and erythrocyte superoxide dismutase capacity levels were increased significantly (p<0.05). Also, there was a non–significant (p>0.05) increase in vitamin E levels as compared to those before supplementation results. Conclusion: Harsh deficiency of various nutrients in severe acute malnutrition leads to generation of heavy oxidative stress. These effects may be minimized with supplementation of antioxidants.

    BACKGROUND—The pharmacological inhibition of exocrine pancreatic secretion with the somatostatin analogue octreotide has been advocated as a specific treatment of acute pancreatitis.
AIM—To investigate the efficacy of octreotide in acute pancreatitis in a randomised, placebo controlled trial.
METHODS—302 patients from 32 hospitals, fulfilling the criteria for moderate to severe acute pancreatitis within 96 hours of the onset of symptoms, were randomly assigned to one of three treatment groups: group P (n=103) received placebo, while groups O1 (n=98) and O2 (n=101) received 100 and 200 µg of octreotide, respectively, by subcutaneous injection three times daily for seven days. The primary outcome variable was a score composed of mortality and 15 typical complications of acute pancreatitis.
RESULTS—The three groups were well matched with respect to pretreatment characteristics. An intent to treat analysis of all 302 patients revealed no significant differences among treatment groups with respect to mortality (P: 16%; O1: 15%; O2: 12%), the rate of newly developed complications, the duration of pain, surgical interventions, or the length of the hospital stay. A valid for efficacy analysis (251 patients) also revealed no significant differences.
CONCLUSIONS—This trial shows no benefit of octreotide in the treatment of acute pancreatitis.

    PURPOSE The aim of this study was to investigate the feasibility of using acoustic radiation force impulse (ARFI) imaging to diagnose acute appendicitis. METHODS Abdominal ultrasonography (US) and ARFI imaging were performed in 53 patients that presented with right lower quadrant pain, and the results were compared with those obtained in 52 healthy subjects. Qualitative evaluation of the patients was conducted by Virtual Touch™ tissue imaging (VTI), while quantitative evaluation was performed by Virtual Touch™ tissue quantification (VTQ) measuring the shear wave velocity (SWV). The severity of appendix inflammation was observed and rated using ARFI imaging in patients diagnosed with acute appendicitis. Alvarado scores were determined for all patients presenting with right lower quadrant pain. All patients diagnosed with appendicitis received appendectomies. The sensitivity and specificity of ARFI imaging relative to US was determined upon confirming the diagnosis of acute appendicitis via histopathological analysis. RESULTS The Alvarado score had a sensitivity and specificity of 70.8% and 20%, respectively, in detecting acute appendicitis. Abdominal US had 83.3% sensitivity and 80% specificity, while ARFI imaging had 100% sensitivity and 98% specificity, in diagnosing acute appendicitis. The median SWV value was 1.11 m/s (range, 0.6–1.56 m/s) for healthy appendix and 3.07 m/s (range, 1.37–4.78 m/s) for acute appendicitis. CONCLUSION ARFI imaging may be useful in guiding the clinical management of acute appendicitis, by helping its diagnosis and determining the severity of appendix inflammation. PMID:25323836

    Marasmus is a severe form of protein-calorie malnutrition characterized by the depletion of fat stores, muscle wasting, and the lack of edema. In developed countries, marasmus is often the result of anorexia nervosa. Abnormal transaminases with liver synthetic dysfunction have rarely been reported with anorexia nervosa. To our knowledge, we report the first detailed case of acute liver injury with severe coagulopathy (INR > 1.5) in a patient with marasmus due to self-induced calorie restriction caused by a somatic delusional disorder. This case highlights the severity of liver injury that may occur with significant weight loss from self-induced calorie restriction and the rapid normalization of this injury with treatment. It is important for clinicians to be aware of patterns of acute liver injury in patients with severe protein-calorie malnutrition, regardless of the underlying cause. PMID:25954537

    A 23-year-old man was admitted to our hospital with severe thrombocytopaenia. He had unprotected sexual contact 6 weeks earlier. He was diagnosed with acute HIV infection by means of HIV RNA viral load testing and HIV-associated thrombocytopaenia. Although his thrombocytopaenia improved immediately with short-term dexamethasone therapy, this effect was not sustained after cessation of therapy. Antiretroviral therapy including raltegravir was initiated, and the patient recovered from severe thrombocytopaenia within several days. The findings from this case suggest that acute HIV infection should be suspected with unexplained thrombocytopaenia, and that antiretroviral therapy is the treatment of choice for severe HIV-associated thrombocytopaenia, even when in the early period following acquisition of the virus.

    Cerebral venous thrombosis- (CVT-) associated headache is considered a secondary headache, commonly presenting as intracranial hypertension headache in association with seizures and/or neurological signs. However, it can occasionally mimic migraine. We report a patient presenting with a migraine-like, CVT-related headache refractory to several medications but intravenous dihydroergotamine (DHE). The response to DHE, which is considered to be an antimigraine medication, in addition to the neurovascular nature of migraine, points out to a probable similarity between CVT-headache and migraine. Based on experimental studies, we discuss this similarity and hypothesize a trigeminovascular role in the genesis of CVT-associated headache. PMID:26989532

  16. Headaches and myofascial temporomandibular disorders: overlapping entities, separate managements?

    There are relevant clinical overlaps between some of the painful temporomandibular disorders (TMD) and headache conditions that may hamper the diagnostic process and treatment. A non-systematic search for studies on the relationship between TMD and headaches was carried out in the following databases: PubMed, Cochrane Library and Embase. Important pain mechanisms contributing to the close association and complex relationship between TMD and headache disorders are as follows: processes of peripheral and central sensitisation which take place in similar anatomical areas, the possible impairment of the descending modulatory pain pathways and the processes of referred pain. In addition, the clinical examination does not always provide distinguishing information to differentiate between headaches and TMD. So, considering the pathophysiology and the clinical presentation of some types of headache and myofascial TMD, such overlap can be considered not only a matter of comorbid relationship, but rather a question of disorders where the distinction lines are sometimes hard to identify. These concerns are certainly reflected in the current classification systems of both TMD and headache where the clinical consequences of diagnosis such as headache attributed to or associated with TMD are uncertain. There are several similarities in terms of therapeutic strategies used to manage myofascial TMD and headaches. Considering all these possible levels of interaction, we reinforce the recommendation for multidisciplinary approaches, by a team of oro-facial pain specialists and a neurologist (headache specialist), to attain the most precise differential diagnosis and initiate the best and most efficient treatment.

    Using a large data set (n = 811), the relationship between acute respiratory infection illness severity and inflammatory biomarkers was investigated to determine whether certain symptoms are correlated more closely than others with the inflammatory biomarkers, interleukin-8 (IL-8) and nasal neutrophils. Participants with community acquired acute respiratory infection underwent nasal lavage for IL-8 and neutrophil testing, in addition to multiplex polymerase chain reaction (PCR) methods for the detection and identification of respiratory viruses. Information about symptoms was obtained throughout the duration of the illness episode using the well-validated Wisconsin Upper Respiratory Symptom Survey (WURSS-21). Global symptom severity was calculated by the area under the curve (AUC) plotting duration versus WURSS total. Of the specimens tested, 56% were positively identified for one or more of nine different respiratory viruses. During acute respiratory infection illness, both IL-8 and neutrophils positively correlate with AUC (rs = 0.082, P = 0.022; rs = 0.080, P = 0.030). IL-8 and neutrophils correlate with nasal symptom severity: runny nose (r = 0.13, P = <0.00001; r = 0.18, P = <0.003), plugged nose (r = 0.045, P = 0.003; r = 0.14, P = 0.058), and sneezing (r = −0.02, P = <0.0001; r = −0.0055, P = 0.31). Neutrophils correlate with some quality of life measures such as sleeping well (r = 0.15, P = 0.026). Thus, the study demonstrates that IL-8 and neutrophils are correlated with severity of nasal symptoms during acute respiratory infection. Further research is necessary to determine if the concentration of these or other biomarkers can predict the overall duration and severity of acute respiratory infection illness. PMID:25132248

    Background Little research has focused on the economic hardship among the insured with severe illnesses and high treatment costs, in particular, the consequence of poorer insurance coverage for high-cost illnesses. Therefore, we presented the case for identifying the experiences of insured patients with severe chronic and acute illnesses. This study identified a qualitative understanding of the economic impact of severe chronic and acute illnesses and household strategies to deal with high treatment costs. Design Interviews were conducted with 19 insured households of three different health insurance programs with a family member that had been hospitalized for severe chronic or acute illnesses in either Banyumas or Margono Sukarjo hospitals in Banyumas, Central Java, Indonesia. A thematic analysis was applied to guide the interpretation of the data. Results Insured households with a family member that had been hospitalized for severe chronic and acute illnesses were greatly affected by the high treatment costs. Four major issues emerged from this qualitative study: insured patients are still burdened with high out-of-pocket payments, households adopt various strategies to cope with the high cost of treatments, households experience financial hardships, and positive and negative perceptions of the insured regarding their health insurance coverage for acute and chronic illnesses. Conclusions Askes and Jamsostek patients faced financial burdens from high cost sharing for hospital amenities, non-covered drugs, and treatments and other indirect costs. Meanwhile, Jamkesmas beneficiaries faced no financial burden for related medical services but were rather burdened with indirect costs for the carers. Households relied on internal resources to cover hospital bills as the first strategy, which included the mobilization of savings, sale of assets, and borrowing of money. External support was tapped secondarily and included financial support from extended family members

    The aim of the study was to evaluate aetiological factors for postoperative headache after vestibular schwannoma (VS) surgery with respect to asymmetric activation of vestibular reflexes. After surgery, 27 VS patients with persistent postoperative headache, 16 VS patients without headache and 9 healthy controls were examined. The vestibular, cervicocollic and cervicospinal reflexes were evaluated to study whether asymmetric activation of vestibular reflexes could cause headache. The effect of neck muscle and occipital nerve anaesthesia and the effect of sumatriptan on headache were also evaluated. The vestibular function of VS patients with headache did not differ from that of VS patients without headache, but was abnormal when compared to that of normal controls. The cervicospinal and cervicocollic reflexes did not differ in the patient groups. Injection of lidocaine around the operation scar gave pain relief to two patients, and one of them had occipital nerve entrapment. Infiltration of lidocaine deep in the neck muscles in the vicinity of the C2 root did not alleviate headache, but caused vertigo. Nine patients with musculogenic headache got pain relief from supportive neck collars, and two patients with cervicobrachial syndrome got pain relief from manual neck traction. The study shows that asymmetric activation of cervicocollic reflexes does not seem to be the reason for headache. Headache seems to be linked to neuropathic pain, allegedly caused by trigeminal irritation of the inner ear and the posterior fossa, which has recently been linked to vascular pain. PMID:10908966

  20. Imaging of Headache in Pregnancy.

    2016-10-01

    Pregnant women are most likely to have primary headaches, such as migraine and tension-type headaches, which can be diagnosed and treated without brain imaging. Primary headaches may even start de novo during pregnancy, especially in the first few months. However, when the headache occurs late in pregnancy or in the peripartum period, secondary causes of headaches need to be considered and evaluated by brain and/or vascular imaging, generally using magnetic resonance techniques. There is considerable overlap between the cerebrovascular complications of pregnancy, including preeclampsia/eclampsia, posterior reversible encephalopathy syndrome (PRES), reversible cerebral vasoconstriction syndrome (RCVS), and both hemorrhagic and ischemic strokes; although, their imaging may be distinctive. Imaging is necessary to distinguish between arterial and venous pathology causing headache in the peripartum patient, as there can be similar presenting symptoms. Mass lesions, both neoplastic and inflammatory, can enlarge and produce headaches and neurological symptoms late in pregnancy. PMID:27562782

  1. Antiepileptic Drug Therapy in Migraine Headache.

    2002-09-01

    Severe migraine affects more than 28 million Americans. It is associated with episodic as well as long-term disability and suffering, yet it is underdiagnosed and undertreated. Acute treatments have advanced considerably, ignited by sumatriptan and the subsequent triptans; unfortunately migraine prevention has lagged far behind. There are no great migraine preventives! No migraine preventive agent studied in good randomized, double blind, placebo-controlled trials proved to be 50% better than placebo. Migraine trials typically focus on episodic migraine, a milder, gentler type of migraine that is selected for low frequency, lack of daily headaches, no preventive need, and previous failure to no more than a few preventive agents. These features are not typical of the usual migraine patient seen in most neurologic practices, thus the results of clinical trials may not carryover to real world situations. Treatment of frequent, chronic, or pervasive migraine is inadequate, and never has been studied in randomized controlled trials. Traditional migraine preventives, eg, beta-blockers, calcium channel blockers, and tricyclic antidepressants, are often ineffective in difficult or complicated populations. The antiepileptic drugs represent a category of pharmaceutics that target the neuronal instability and central hyperexcitability of migraine, and, through these actions, may be more effective than traditional preventives. Episodic migraine attacks are associated with peripheral and central sensitization; however, if attacks are frequent, severe, or long lasting, this sensitization may increase the risk of developing daily headaches. If antiepileptic drugs have an effect on central sensitization, perhaps mediated via glutamate inhibition or gamma-aminobutyric acid potentiation, it is appropriate to use these agents early in migraine treatment, particularly in the highly comorbid patient, possibly in conjunction with agents that antagonize the 5HT2 receptor.

    Mesenchymal stem cells (MSC) are a kind of non-hematopoietic adult stem cells with self-renewal and multilineage differentiation potential, which have special biological characteristics, such as secreting various cytokines, promoting hematopoiesis, accelerating stem cells homing and reconstructing hematopoietic microenvironment. MSC are collected and amplified easily, and can be transfected by exogenous gene. Many reports indicated that MSC were applied in therapy for variety of tissues and organs injury, meanwhile the treatment for acute radiation sickness has made significant progress. In this review, the biological characteristics and new research advance on MSC in treatment of severe acute radiation sickness are summarized and discussed. PMID:21729581

    Many patients with migraine believe weather is a trigger for their headaches. The objective of this study was to determine if very low frequency sferics, pulse-shaped electromagnetic fields originating from atmospheric discharges (lightning), are precipitating factors. The occurrence of sferics impulses is characterized by a daily, as well as an annual, periodicity and is thought to be associated with various pathological processes. The diaries of 37 women suffering from migraine and tension-type headaches were analyzed over a period of 6 months and correlated with daily sferics activity and other weather phenomena in the area of Giessen, Germany. From October through December (autumn), sferics activity was correlated with the occurrence of migraine (r = 0.33, P<.01); however, there was no correlation in July and August (summer), when the thunderstorm activity had been very intense. In summer, tension-type headaches were associated with other weather parameters such as temperature (r = 0.36, P<.01) and vapor pressure (r = 0.27, P<.05). PMID:11703470

    Introduction Pancreatitis is one of most complex and clinically challenging of all abdominal disorders. USG and abdominal CT are the most commonly used diagnostic imaging modalities for the evaluation of pancreas. Computed Tomography (CT) is highly accurate and sensitive than USG in both diagnosing as well as demonstrating the extent. Early assessment of the cause and severity of acute pancreatitis is of utmost importance for prompt treatment and close monitoring of patient with severe disease. CT is the imaging method of choice for assessing the extent of acute pancreatitis and for evaluating complications. Aim To assess prognostic correlation and clinical outcome of acute pancreatitis on the basis of CT severity index. Materials and Methods A prospective study of 50 cases was carried out in the Department of Radio Diagnosis, with complaint suggestive of acute pancreatitis on the basis of clinical/laboratory/ultrasonography findings were evaluated in Siemens somatom 40 slice CT. The severity of pancreatitis was scored using CT severity index, modified severity index and revised Atlanta classification and classified into mild, moderate, severe categories. Clinical follow-up of the patients was done in terms of the following parameters: Length of hospital stay, Need for surgery or percutaneous intervention, Evidence of infection in any organ system, Occurrence of organ failure- respiratory, cardiovascular, renal, hepatic and haematological system, death. The clinical outcome was compared with the currently accepted Balthazar’s CTSI and Modified Mortele’s CTSI and revised Atlanta classification in all the cases. Results Gall stone disease was most common aetiological factor seen in 40% cases, it was more common in females than males. Alcohol was second most common aetiological factor seen in 38% cases and was noted only in males. Pleural effusion was the most common extra-pancreatic complication seen in 46% cases. Balthazar grade C was the most common (40

    Although there are high survival rates for children with acute lymphoblastic leukaemia, their outcome is often counterbalanced by the burden of toxic effects. This is because reported frequencies vary widely across studies, partly because of diverse definitions of toxic effects. Using the Delphi method, 15 international childhood acute lymphoblastic leukaemia study groups assessed acute lymphoblastic leukaemia protocols to address toxic effects that were to be considered by the Ponte di Legno working group. 14 acute toxic effects (hypersensitivity to asparaginase, hyperlipidaemia, osteonecrosis, asparaginase-associated pancreatitis, arterial hypertension, posterior reversible encephalopathy syndrome, seizures, depressed level of consciousness, methotrexate-related stroke-like syndrome, peripheral neuropathy, high-dose methotrexate-related nephrotoxicity, sinusoidal obstructive syndrome, thromboembolism, and Pneumocystis jirovecii pneumonia) that are serious but too rare to be addressed comprehensively within any single group, or are deemed to need consensus definitions for reliable incidence comparisons, were selected for assessment. Our results showed that none of the protocols addressed all 14 toxic effects, that no two protocols shared identical definitions of all toxic effects, and that no toxic effect definition was shared by all protocols. Using the Delphi method over three face-to-face plenary meetings, consensus definitions were obtained for all 14 toxic effects. In the overall assessment of outcome of acute lymphoblastic leukaemia treatment, these expert opinion-based definitions will allow reliable comparisons of frequencies and severities of acute toxic effects across treatment protocols, and facilitate international research on cause, guidelines for treatment adaptation, preventive strategies, and development of consensus algorithms for reporting on acute lymphoblastic leukaemia treatment.

    2013-01-01

    Background Headache disorders are the most common complaints worldwide. Migraine, tension type and cluster headaches account for majority of primary headaches and improvise a substantial burden on the individual, family or society at large. There is a scanty data on the prevalence of primary headaches in sub-Saharan Africa in general and Ethiopia in particular. Moreover there is no population based urban study in Ethiopia. The purpose of this study is to determine the prevalence and burden of primary headaches in local community in Addis Ababa, Ethiopia. Methods Cross-sectional sample survey was carried out in Addis Ketema sub city, Kebele 16/17/18 (local smallest administrative unit). Using systematic random sampling, data were collected by previously used headache questionnaire, over a period of 20 days. Results The study subjects were 231 of which 51.5% were males and 48.5% were females. The overall one year prevalence of primary headache disorders was 21.6% and that for migraine was 10%, migraine without aura 6.5% migraine with aura was 2.6% and probable migraine was 0.9%. The prevalence of tension type of headache was found to be 10.4%, frequent episodic tension type headache was 8.2% followed by infrequent tension type headache of 2.2%. The prevalence of cluster headache was 1.3%. The burden of primary headache disorders in terms of missing working, school or social activities was 68.0%. This was 78.3% for migraineurs and 66.7% for tension type headache. Majority 92.0% of primary headache cases were not using health services and 66.0% did not use any drug or medications during the acute attacks and none were using preventive therapy. Conclusion Prevalence and burden of primary headache disorders was substantial in this community. Health service utilization of the community for headache treatment was poor. PMID:23574933

    2015-01-01

    Trigeminal autonomic cephalalgias (TACs) are a group of primary headaches including cluster headache (CH), paroxysmal hemicrania (PH) and short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT). Another form, hemicrania continua (HC), is also included this group due to its clinical and pathophysiological similarities. CH is the most common of these syndromes, the others being infrequent in the general population. The pathophysiology of the TACs has been partly elucidated by a number of recent neuroimaging studies, which implicate brain regions associated with nociception (pain matrix). In addition, the hypothalamic activation observed in the course of TAC attacks and the observed efficacy of hypothalamic neurostimulation in CH patients suggest that the hypothalamus is another key structure. Hypothalamic activation may indeed be involved in attack initiation, but it may also lead to a condition of central facilitation underlying the recurrence of pain episodes. The TACs share many pathophysiological features, but are characterised by differences in attack duration and frequency, and to some extent treatment response. Although alternative strategies for the TACs, especially CH, are now emerging (such as neurostimulation techniques), this review focuses on the available pharmacological treatments complying with the most recent guidelines. We discuss the clinical efficacy and tolerability of the currently used drugs. Due to the low frequency of most TACs, few randomised controlled trials have been conducted. The therapies of choice in CH continue to be the triptans and oxygen for acute treatment, and verapamil and lithium for prevention, but promising results have recently been obtained with novel modes of administration of the triptans and other agents, and several other treatments are currently under study. Indomethacin is extremely effective in PH and HC, while antiepileptic drugs (especially lamotrigine) appear to be

    Objective Optimal care of adults with severe acute respiratory failure requires specific resources and expertise. We sought to measure geographic access to these centers in the United States. Design Cross-sectional analysis of geographic access to high capability severe acute respiratory failure centers in the United States. We defined high capability centers using two criteria: (1) provision of adult extracorporeal membrane oxygenation (ECMO), based on either 2008–2013 Extracorporeal Life Support Organization reporting or provision of ECMO to 2010 Medicare beneficiaries; or (2) high annual hospital mechanical ventilation volume, based 2010 Medicare claims. Setting Nonfederal acute care hospitals in the United States. Measurements and Main Results We defined geographic access as the percentage of the state, region and national population with either direct or hospital-transferred access within one or two hours by air or ground transport. Of 4,822 acute care hospitals, 148 hospitals met our ECMO criteria and 447 hospitals met our mechanical ventilation criteria. Geographic access varied substantially across states and regions in the United States, depending on center criteria. Without interhospital transfer, an estimated 58.5% of the national adult population had geographic access to hospitals performing ECMO and 79.0% had geographic access to hospitals performing a high annual volume of mechanical ventilation. With interhospital transfer and under ideal circumstances, an estimated 96.4% of the national adult population had geographic access to hospitals performing ECMO and 98.6% had geographic access to hospitals performing a high annual volume of mechanical ventilation. However, this degree of geographic access required substantial interhospital transfer of patients, including up to two hours by air. Conclusions Geographic access to high capability severe acute respiratory failure centers varies widely across states and regions in the United States. Adequate

    Diagnosing a rhinogenic cause of headache or facial pain outside of the classic definitions of chronic, acute, and subacute sinusitis can be challenging for the practicing otolaryngologist. Contact-point headaches have been clinically characterized as causing facial pain secondary to abutting mucosal contact from the lateral nasal wall to the septum. Imaging landmarks may help identify these potential contact points radiographically through revealing anatomic variants such as septal spurs and abnormally large lateral nasal structures. However, other potential rhinologic sources, such as barosinusitis, recurrent barotrauma, or recurrent acute sinusitis occurring between active episodes, are challenging to identify through hallmark imaging findings.

    Background: Many studies have reported that depression and anxiety have bidirectional relationship with headache. However, few researches investigated the roles of depression or anxiety in patients with headache. We surveyed the prevalence of depression and anxiety as a complication or cause of headache among outpatients with a chief complaint of headache at neurology clinics in general hospitals. Additional risk factors for depression and anxiety were also analyzed. Methods: A cross-sectional study was conducted at 11 general neurological clinics. All consecutive patients with a chief complaint of headache were enrolled. Diagnoses of depression and anxiety were made using the Chinese version of the Mini International Neuropsychiatric Interview, and those for headache were made according to the International Classification of Headache Disorders, 2nd Edition. The headache impact test and an 11-point verbal rating scale were applied to assess headache severity and intensity. Logistic regression was used to analyze risk factors of patients with headache for depression or anxiety. Results: A total of 749 outpatients with headache were included. Among them, 148 (19.7%) were diagnosed with depression and 103 (13.7%) with anxiety. Further analysis showed that 114 (15.2%) patients complaining headache due to somatic symptoms of psychiatric disorders and 82 (10.9%) had a depression or anxiety comorbidity with headache. Most patients with depression or anxiety manifested mild to moderate headaches. Poor sleep and severe headache-related disabilities were predictors for either depression or anxiety. Conclusion: Clinicians must identify the etiology of headache and recognize the effects of depression or anxiety on headache to develop specific treatments. PMID:27270532

    The genomic sequences of severe acute respiratory syndrome coronaviruses from human and palm civet of the 2003/2004 outbreak in the city of Guangzhou, China, were nearly identical. Phylogenetic analysis suggested an independent viral invasion from animal to human in this new episode. Combining all existing data but excluding singletons, we identified 202 single-nucleotide variations. Among them, 17 are polymorphic in palm civets only. The ratio of nonsynonymous/synonymous nucleotide substitution in palm civets collected 1 yr apart from different geographic locations is very high, suggesting a rapid evolving process of viral proteins in civet as well, much like their adaptation in the human host in the early 2002–2003 epidemic. Major genetic variations in some critical genes, particularly the Spike gene, seemed essential for the transition from animal-to-human transmission to human-to-human transmission, which eventually caused the first severe acute respiratory syndrome outbreak of 2002/2003.

    SUMMARY The reason(s) that hepatitis A virus (HAV) infection may progress infrequently to acute liver failure are poorly understood. We examined host and viral factors in 29 consecutive adult patients with HAV-associated acute liver failure enrolled at 10 sites participating in the US ALF Study Group. Eighteen of twenty-four acute liver failure sera were PCR positive while six had no detectable virus. HAV genotype was determined using phylogenetic analysis and the full-length genome sequences of the HAV from a cute liver failure sera were compared to those from self-limited acute HAV cases selected from the CDC database. We found that rates of nucleotide substitution did not vary significantly between the liver failure and non-liver failure cases and there was no significant variation in amino acid sequences between the two groups. Four of 18 HAV isolates were subgenotype IB, acquired from the same study site over a 3.5-year period. Sub-genotype IB was found more frequently among acute liver failure cases compared to the non-liver failure cases (chi-square test, P < 0.01). At another centre, a mother and her son presented with HAV and liver failure within 1 month of each other. Predictors of spontaneous survival included detectable serum HAV RNA, while age, gender, HAV genotype and nucleotide substitutions were not associated with outcome. The more frequent appearance of rapid viral clearance and its association with poor outcomes in acute liver failure as well as the finding of familial cases imply a possible host genetic predisposition that contributes to a fulminant course. Recurrent cases of the rare subgenotype IB over several years at a single centre imply a community reservoir of infection and possible increased pathogenicity of certain infrequent viral genotypes.

    Radiation accidents or terrorist attacks can result in serious consequences for the civilian population and for military personnel responding to such emergencies. The early medical management situation requires quantitative indications for early initiation of cytokine therapy in individuals exposed to life-threatening radiation doses and effective triage tools for first responders in mass-casualty radiological incidents. Previously established animal (Mus musculus, Macaca mulatta) total-body irradiation (γ-exposure) models have evaluated a panel of radiation-responsive proteins that, together with peripheral blood cell counts, create a multiparametic dose-predictive algorithm with a threshold for detection of ~1 Gy from 1 to 7 d after exposure as well as demonstrate the acute radiation syndrome severity score systems created similar to the Medical Treatment Protocols for Radiation Accident Victims developed by Fliedner and colleagues. The authors present a further demonstration of the acute radiation sickness severity score system in a mouse (CD2F1, males) TBI model (1-14 Gy, Co γ-rays at 0.6 Gy min) based on multiple biodosimetric endpoints. This includes the acute radiation sickness severity Observational Grading System, survival rate, weight changes, temperature, peripheral blood cell counts and radiation-responsive protein expression profile: Flt-3 ligand, interleukin 6, granulocyte-colony stimulating factor, thrombopoietin, erythropoietin, and serum amyloid A. Results show that use of the multiple-parameter severity score system facilitates identification of animals requiring enhanced monitoring after irradiation and that proteomics are a complementary approach to conventional biodosimetry for early assessment of radiation exposure, enhancing accuracy and discrimination index for acute radiation sickness response categories and early prediction of outcome.

    Severe acute pancreatitis is a clinical entity that can develop into multiple organ failure (MOF), and still has a poor prognosis. It is generally agreed that excessive humoral mediators such as pro-inflammatory cytokines play important roles in the pathogenesis of organ failure in patients with severe acute pancreatitis (SAP). Furthermore, it has been reported that continuous hemodiafiltration (CHDF) can remove the excess humoral mediators during the hypercytokinemic state of systemic inflammatory response syndrome (SIRS). We experienced a case of severe acute pancreatitis induced by alcohol abuse, on whom we performed cytokine apheresis. The patient was a 46 year-old male. He received 14 cytokine apheresis procedures, for about 4 hours in each session, using a CTR-001 direct hemoperfusion (DHP) cartridge. His serum levels of pro-inflammatory cytokines such as interleukin-6 (IL-6; 1649.1+/-667.1-1257.1+/-489.4 pg/mL, P=0.013) decreased significantly after the CTR-001 procedures. However tumor necrosis factor-alpha (TNF-alpha) (26.2+/-1.7-24.3+/-1.9 pg/mL, P=0.087), IL-1beta (6.1+/-2.9-3.49+/-1.1 pg/mL, P=0.477), IL-8 (192.5+/-33.4-229.5+/-51.8 pg/mL, P=0.754) and IL-10 (14.4+/-2.7-14.0+/-1.9 pg/mL, P=0.726) did not decrease statistically. Therefore, we conclude that in this case, cytokine apheresis using a CTR-001 cartridge was effective for reducing the pro-inflammatory cytokines during severe acute pancreatitis. PMID:16076384

    Headache and temporomandibular disorders should be treated together but separately. If there is marked limitation of opening, imaging of the joint may be necessary. The treatment should then include education regarding limiting jaw function, appliance therapy, instruction in jaw posture, and stretching exercises, as well as medications to reduce inflammation and relax the muscles. The use of physical therapies, such as spray and stretch and trigger point injections, is helpful if there is myofascial pain. Tricyclic antidepressants and the new-generation antiepileptic drugs are effective in muscle pain conditions. Arthrocentesis and/or arthroscopy may help to restore range of motion. PMID:24703543

    In two surveys of headaches it was noted that their incidence had increased significantly within 48 h prior to earthquakes from an incidence of 17% to 58% in the first survey using correlated samples and from 20.4% to 44% in the second survey using independent samples. It is suggested that an increase in positive air ions from rock compression may trigger head pain via a decrease in brain levels of the neurotransmitter serotonin. The findings are presented as preliminary, with the hope of generating further research efforts in areas more prone to earthquakes.

    Summary Purpose hamstring injury is the most common musculoskeletal disorder and one of the main causes of missed sporting events. Shortening the time to return to play (TTRTP) is a priority for athletes and sports medicine practitioners. Hypothesis platelet-rich plasma (PRP) injection at the site of severe acute hamstring injury increases the healing rate and shortens the TTRTP. Study design Cohort study. Methods all patients with ultrasonography and MRI evidence of severe acute hamstring injury between January 2012 and March 2014 were offered PRP treatment. Those who accepted received a single intramuscular PRP injection within 8 days post-injury; the other patients served as controls. The same standardized rehabilitation program was used in both groups. A physical examination and ultrasonography were performed 10 and 30 days post-injury, then a phone interview 120 days post-injury, to determine the TTRTP at the pre-injury level. Results of 34 patients, 15 received PRP and 19 did not. Mean TTRTP at the pre-injury level was 50.9±10.7 days in the PRP group and 52.8±15.7 days in the control group. The difference was not statistically significant. Conclusion a single intramuscular PRP injection did not shorten the TTRTP in sports people with severe acute hamstring injuries. PMID:26958537

    We report the case of a 22-year old man with intracranial metallic foreign bodies who presented complaining of a headache. His history of headaches had begun when he was five years old and continued with increasing severity. Six months before hospital admission, nausea and vomiting began to accompany his headache. Computed tomography scan revealed that 2 metallic foreign bodies were located adjacent to the vertex and another was next to the ambient cistern. The location and position of foreign bodies suggested that they were introduced in infancy through the anterior fontanelle before its closure in an unsuccessful homicide attempt. This case is one of the few reported cases combining headache and intracranial foreign bodies and we discuss the relationship between headache and these metallic materials. PMID:23355931

    To analyze autonomic nervous system activity in headache subjects, measurements of heart rate variability (HRV), skin temperature, skin conductance, and respiration were compared to a matched control group. HRV data were recorded in time and frequency domains. Subjects also completed self-report questionnaires assessing psychological distress, fatigue, and sleep dysfunction. Twenty-one headache and nineteen control subjects participated. In the time domain, the number of consecutive R-to-R intervals that varied by more than 50 ms and the standard deviation of the normalized R-to-R intervals, both indices of parasympathetic nervous system activity, were significantly lower in the headache group than the control group. Groups did not differ statistically on HRV measures in the frequency domain. Self-report measures showed significantly increased somatization, hostility, anxiety, symptom distress, fatigue, and sleep problems in the headache group. The results suggest headache subjects have increased sympathetic nervous system activity and decreased parasympathetic activity compared to non-headache control subjects. Headaches subjects also showed greater emotional distress, fatigue, and sleep problems. The results indicate an association between headaches and cardiovascular functioning suggestive of sympathetic nervous system activation in this sample of mixed migraine and tension-type headache sufferers.

    Neurostimulation techniques for the treatment of primary headache syndromes, particularly of chronic cluster headache, have received much interest in recent years. Occipital nerve stimulation (ONS) has yielded favourable clinical results and, despite the limited numbers of published cases, is becoming a routine treatment for refractory chronic cluster headache in specialized centres. Meanwhile, other promising techniques such as spinal cord stimulation (SCS) or sphenopalate ganglion stimulation have emerged. In this article the current state of clinical research for neurostimulation techniques for chronic cluster headache is reviewed. PMID:22590481

    Lung-protective ventilation with a low tidal volume, plateau pressure < 30 cm H(2)O. oxygen saturation > 90% and permissive hypercapnia results in reduction of the mortality rate in patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). The level of the positive end-expiratory pressure (PEEP) must be chosen in relation to oxygen requirement. High frequency oscillatory ventilation and neurally adjusted ventilatory assist are promising methods. However, further studies with firm end-points have to be awaited before a final judgment is possible. Veno-venous extracorporeal membrane oxygenation (ECMO) can ensure life-sustaining gas exchange in patients with severe vitally compromised pulmonary failure, to provide time for lung tissue to heal and reduce ventilatory stress. The latest guidelines for analgesia and sedation in intensive care medicine demand consistent monitoring of the level of sedation and the intensity of pain. The sedation should be interrupted daily, with phases of awakenings and, if possible, spontaneous breathing. Methods of supportive treatment: Positional treatment (prone position) and inhalation of vasodilators can improve ventilation/perfusion mismatch and thus oxygenation. However, administration of surfactant is currently not advised in adult respiratory failure. PMID:21271478

    Peripartum cardiomyopathy is a cardiac disease at high thromboembolism potential. The authors report a case of peripartum cardiomyopathy admitted for congestive heart failure. Echocardiography found a dilated cardiomyopathy with severely impaired left ventricular systolic function and biventricular thrombi. During hospitalization his condition was complicated by severe bilateral pulmonary embolism and left lower limb arterial acute thrombosis. The treatment consisted of thrombolysis with streptokinase associated with dobutamine (in addition to the conventional treatment of heart failure and bromocriptine). The outcome was favorable, marked by pulmonary and lower limb arterial unblocking. PMID:25623958

It also exposed major weaknesses in several of these countries in coping with an outbreak of a newly emerged infectious disease. In the 10 years since the outbreak, in addition to the increase in knowledge of the biology and epidemiology of this disease, a major lesson learned is the value of having a national public health institute that is prepared to control disease outbreaks and designed to coordinate a national response and assist localities in their responses.

    Aquaporin-1 (AQP-1) is expressed in lung endothelial cells and regulates water transport; thus, AQP-1 plays an important role in a number of edema-associated lung diseases. Qing Yin Tang (QYT), a traditional Chinese medicine, has been shown to effectively reduce the mortality rate of acute lung injury (ALI) induced by severe acute pancreatitis (SAP). The current study aimed to investigate the detailed mechanisms underlying the effects of QYT on ALI induced by SAP, particularly the effects on the expression levels of AQP-1 in the lung tissue. ALI was established in Wister rats who were subsequently divided into four groups: SHAM, ALI, dexamethasone (DEX) and QYT groups (n=8 per group). In the QYT group, 20 ml/kg QYT was administered by gavage immediately following the induction of SAP. Blood and lung tissues were collected 8 h following the induction of pancreatitis. The lung wet/dry ratio, as well as the levels of blood gases, serum amylase and tumor necrosis factor-α (TNF-α), were measured at 4, 8 and 12 h following SAP-associated ALI induction surgery. The expression levels of AQP-1 in the lung tissue were detected by quantitative polymerase chain reaction, immunohistochemistry and western blot analysis. No statistically significant differences were observed with regard to the levels of serum amylase, wet/dry ratio, partial pressure of oxygen, serum TNF-α and pathological changes in the pulmonary tissue between the QYT and DEX groups; however, a statistically significant difference was observed when compared with the ALI group. The expression levels of AQP-1 significantly increased (P<0.05) and lung edema was alleviated in the QYT and DEX groups, when compared with ALI group. Therefore, the expression level of AQP-1 is associated with pulmonary edema. QYT protects the lungs from injury induced by SAP via the upregulation of AQP-1, which suppresses TNF-α expression.

    Acute kidney injury (AKI) is a common complication after severe burns. Melatonin has been reported to protect against multiple organ injuries by increasing the expression of SIRT1, a silent information regulator that regulates stress responses, inflammation, cellular senescence and apoptosis. This study aimed to investigate the protective effects of melatonin on renal tissues of burned rats and the role of SIRT1 involving the effects. Rat severely burned model was established, with or without the administration of melatonin and SIRT1 inhibitor. The renal function and histological manifestations were determined to evaluate the severity of kidney injury. The levels of acetylated-p53 (Ac-p53), acetylated-p65 (Ac-p65), NF-κB, acetylated-forkhead box O1 (Ac-FoxO1), Bcl-2 and Bax were analyzed to study the underlying mechanisms. Our results suggested that severe burns could induce acute kidney injury, which could be partially reversed by melatonin. Melatonin attenuated oxidative stress, inflammation and apoptosis accompanied by the increased expression of SIRT1. The protective effects of melatonin were abrogated by the inhibition of SIRT1. In conclusion, we demonstrate that melatonin improves severe burn-induced AKI via the activation of SIRT1 signaling. PMID:27599451

    It is unknown whether gastroesophageal reflux disease (GERD) during infancy affects infant bronchiolitis severity or childhood asthma inception. Four hundred thirty-two infants presenting with acute respiratory illness due to bronchiolitis or upper respiratory infection were studied. The primary exposure was the parental report of a previous GERD diagnosis. Outcomes included bronchiolitis severity at initial presentation and childhood asthma diagnosis at age 4. Infants with parentally reported GERD had a higher bronchiolitis severity score (range=0-12, clinically significant difference=0.5), indicating more severe disease, than infants without reported GERD (median 5.5 [interquartile range 3.5-9.0] among those with reported GERD versus 4.0 [1.0-7.0] among those without, P=0.005). This association persisted after adjusting for infant age, race, gender, and secondhand smoke exposure by a propensity score (adjusted odds ratio [OR] 1.99, 95% confidence interval [CI] 1.14-3.46, P=0.02). The parental report of GERD during infancy was not associated with the parental report of asthma diagnosis at age 4. GERD during infancy may contribute to acute respiratory illness severity, but is not associated with asthma diagnosis at age 4. Future prospective studies are needed to confirm these findings.

    Background and Objectives The onset of pervasive sleep-wake disturbances associated with traumatic brain injury (TBI) is poorly understood. This study aimed to (a) determine the feasibility of using polysomnography in patients in the acute, hospitalized stage of severe TBI and (b) explore sleep quality and sleep architecture during this stage of recovery, compared to patients with other traumatic injuries. Methods A cross-sectional case-control design was used. We examined the sleep of 7 patients with severe TBI (17-47 years; 20.3 ± 15.0 days postinjury) and 6 patients with orthopedic and/or spinal cord injuries (OSCI; 19-58 years; 16.9 ± 4.9 days postinjury). One night of ambulatory polysomnography was performed at bedside. Results Compared to OSCI patients, TBI patients showed a significantly longer duration of nocturnal sleep and earlier nighttime sleep onset. Sleep efficiency was low and comparable in both groups. All sleep stages were observed in both groups with normal proportions according to age. Conclusion Patients in the acute stage of severe TBI exhibit increased sleep duration and earlier sleep onset, suggesting that the injured brain enhances sleep need and/or decreases the ability to maintain wakefulness. As poor sleep efficiency could compromise brain recovery, further studies should investigate whether strategies known to optimize sleep in healthy individuals are efficacious in acute TBI. While there are several inherent challenges, polysomnography is a useful means of examining sleep in the early stage of recovery in patients with severe TBI. PMID:26704256

    Objective Headaches are common neurologic problems for children and adolescents. They are divided into two types: primary and secondary. Primary headaches include migraines and tension-type as well as comprise the majority of headaches. We detect the causes of headaches and their associations with demographic variables among children and adolescents. Materials & Methods This cross-sectional study was performed on 5–15 year-old children with headaches from March 2010 to April 2012 who presented at a pediatric neurology clinic in Kashan, Iran. Diagnosis of headaches was done in accordance with the International Classification of Headache Disorders. Data regarding the type of headache, age, gender, pain severity, aura, family history, and sleep disorder were collected. Results One hundred fourteen children (44 male and 70 female) with headaches were enrolled in the study. The types of headaches were comprised as follows: 67 cases of migraines, 38 cases of tension-type headaches, 2 cases of cluster headaches, and 7 cases of secondary headaches. Pulsating headaches, family history of headaches, insomnia, and pain severity had higher prevalence in migrainous patients. Conclusion Physicians should extend their information gathering about primary and secondary headaches. Sleep disturbances and a family history of headaches were the most important factors associated with migraine headaches. PMID:25767542

    Sepsis continues to account for a second peak in mortality in patients with severe acute pancreatitis. The prevention of these septic complications and subsequent development of multiple organ dysfunction syndrome remains a major focus for investigators, yet despite considerable clinical and experimental work addressing its etiology, septic complications remain high. Several studies have been designed to demonstrate the mechanism of origin of these septic complications with an attempt to define strategies for their prevention to improve patient outcomes. There is clear evidence that the origin of this secondary bacterial infection arises from enteric bacterial translocation secondary to disruption of the gut mucosal barrier during acute pancreatitis. Strategies designed to prevent secondary pancreatic infection include aggressive fluid resuscitation to maximize organ perfusion, early systemic antibiotic treatment or selective gut decontamination, and recently attempts to block mediators of the systemic inflammatory response. This discussion will summarize our present understanding of the etiopathogenesis of secondary bacterial 'superinfection' of necrotizing pancreatitis and how the initiation of enteral feeding early in the course of acute pancreatitis may prove to be an effective means of preventing and/or reversing the breakdown of the gut mucosal defense barrier.

    Objective To examine whether stroke survivors with more severe spatial neglect during their acute inpatient rehabilitation had poorer mobility after returning to their communities. Design A prospective observational study. Setting Acute inpatient rehabilitation and follow-up in the community. Participants Thirty-one consecutive stroke survivors with right-brain damage (women, n = 15 [48.4%]), with the mean (standard deviation) age of 60 ± 11.5 years, were included in the study if they demonstrated spatial neglect within 2 months after stroke. Methods Spatial neglect was assessed with the Behavioral Inattention Test (BIT) (range, 0-146 [a lower score indicates more severity]) and the Catherine Bergego Scale (range, 0-30 [a higher score indicates more severity]). A score of the Behavioral Inattention Test <129 or of the Catherine Bergego Scale >0 defined the presence of spatial neglect. Main Outcome Measurements The outcome measure is community mobility, defined by the extent and frequency of traveling within the home and in the community, and is assessed with the University of Alabama at Birmingham Study of Aging Life-Space Assessment (range, 0-120 [a lower score indicates less mobile]). This measure was assessed after participants returned home ≥6 months after stroke. The covariates were age, gender, functional independence at baseline; follow-up interval; and depressed mood, which may affect the relationship between spatial neglect and community mobility. Results A lower Behavioral Inattention Test score was a significant predictor of a lower Life-Space Assessment score after controlling for all the covariates (β = 0.009 [95% confidence interval, 0.008-0.017]); P = .020). The proportion of participants unable to travel independently beyond their homes was 0%, 27.3%, and 72.7% for those with mild, moderate, and severe acute neglect, respectively (Catherine Bergego Scale range, 1-10, 11-20, and 21-30, respectively).

    OBJECTIVE: A randomized, controlled, multicenter trial was undertaken in 102 patients with objective evidence of severe acute pancreatitis to evaluate whether selective decontamination reduces mortality. SUMMARY BACKGROUND DATA: Secondary pancreatic infection is the major cause of death in patients with acute necrotizing pancreatitis. Controlled clinical trials to study the effect of selective decontamination in such patients are not available. METHODS: Between April 22, 1990 and April 19, 1993, 102 patients with severe acute pancreatitis were admitted to 16 participating hospitals. Patients were entered into the study if severe acute pancreatitis was indicated, on admission, by multiple laboratory criteria (Imrie score > or = 3) and/or computed tomography criteria (Balthazar grade D or E). Patients were randomly assigned to receive standard treatment (control group) or standard treatment plus selective decontamination (norfloxacin, colistin, amphotericin; selective decontamination group). All patients received full supportive treatment, and surveillance cultures were taken in both groups. RESULTS: Fifty patients were assigned to the selective decontamination group and 52 were assigned to the control group. There were 18 deaths in the control group (35%), compared with 11 deaths (22%) in the selective decontamination group (adjusted for Imrie score and Balthazar grade: p = 0.048). This difference was mainly caused by a reduction of late mortality (> 2 weeks) due to significant reduction of gram-negative pancreatic infection (p = 0.003). The average number of laparotomies per patient was reduced in patients treated with selective decontamination (p < 0.05). Failure of selective decontamination to prevent secondary gram-negative pancreatic infection with subsequent death was seen in only three patients (6%) and transient gram-negative pancreatic infection was seen in one (2%). In both groups of patients, all gram-negative aerobic pancreatic infection was preceded by

    Severe acute pancreatitis (SAP) is an acute abdominal disease with the strong systemic inflammatory response, and rapidly progresses from a local pancreatic damage into multiple organ dysfunction. For many decades, the contributions of neutrophils to the pathology of SAP were traditionally thought to be the chemokine and cytokine cascades that accompany inflammation. In this review, we focus mainly on those recently recognized aspects of neutrophils in SAP processes. First, emerging evidence suggests that therapeutic interventions targeting neutrophils significantly lower tissue damage and protect against the occurrence of pancreatitis. Second, trypsin activation promotes the initial neutrophils recruitment into local pancreas, and subsequently neutrophils infiltration in turn triggers trypsin production. Finally, neutrophils have the unique ability to release neutrophil extracellular traps even in the absence of pathogens. PMID:26249268

    We report four cases of acute pulmonary edema that occurred during treatment by intravenous tocolysis using nicardipine in pregnancy patients with no previous heart problems. Clinical severity justified hospitalization in intensive care unit (ICU) each time. Acute dyspnea has begun at an average of 63 hours after initiation of treatment. For all patients, the first diagnosis suspected was pulmonary embolism. The patients' condition improved rapidly with appropriate diuretic treatment and by modifying the tocolysis. The use of intravenous nicardipine is widely used for tocolysis in France even if its prescription does not have a marketing authorization. The pathophysiological mechanisms of this complication remain unclear. The main reported risk factors are spontaneous preterm labor, multiple pregnancy, concomitant obstetrical disease, association with beta-agonists, and fetal lung maturation corticotherapy. A better knowledge of this rare but serious adverse event should improve the management of patients. Nifedipine or atosiban, the efficiency of which tocolysis was also studied, could be an alternative. PMID:25215245

    Photochemical/thermal retinal damage that results from unprotected solar eclipse viewing has vague presentations and sometimes misleading diagnosis, especially in cases with unclear history. Spectral-domain optical coherence tomography (SD-OCT) is a non-invasive imaging technique useful in differential diagnosis that can reveal characteristic foveal alterations in solar retinopathy to an unprecedented quasi histologic level. The authors present high-resolution SD-OCT findings correlated with clinical findings in three eyes of two cases with acute solar retinopathy. SD-OCT can precisely define the site and extent of damage in acute solar retinopathy. In mild forms, damage may be limited to the outer retina with inner segment/outer segment disruption. In severe forms, full thickness macular damage may be seen. Advances in retinal imaging have improved our ability to provide precise correlation with clinical presentation and prognosis.

    We investigated the utility of noncontrast enhanced endosonography (EUS) in predicting the severity of acute pancreatitis (AP) during the first 72 to 96 h of admission.In total, 187 patients with acute biliary pancreatitis were included. The patients were classified into 2 groups as having severe and mild AP according to the Modified Glasgow scoring and computerized tomography severity index (SI). The 158 cases with mild and 29 cases with severe AP had a similar age and sex distribution.Although none of the cases with mild AP developed morbidity and death, of the cases with severe AP, 16 developed serious morbidities and 5 died. On EUS examination, we looked for parenchymal findings, peripancreatic inflammatory signs, free or loculated fluid collections, and abnormalities of the common bile duct and the pancreatic channel. Statistical analysis indicated a significant relationship between the severity of AP with diffuse parenchymal edema, periparenchymal plastering, and/or diffuse retroperitoneal free fluid accumulation, and peri-pancreatic edema. We also defined an EUSSI and found that the EUSSI had sensitivity of 89.7%, specificity of 84.2%, positive predictivity value (PPV) of 88.9%, negative predictivity value (NPV) of 91.2%, and an accuracy of 87.9% in the differentiation of mild and severe AP. We found that the EUSSI had an accuracy of 72.4%, sensitivity of 75.4%, specificity of 65.1%, PPV of 69.3%, and NPV of 73.1% for determining mortality.Our data suggest that EUS allowed us to accurately predict the severity and mortality in nearly 90% of cases with AP.

    Background.  Acute kidney injury (AKI) is a well recognized complication of severe malaria in adults, but the incidence and clinical importance of AKI in pediatric severe malaria (SM) is not well documented. Methods.  One hundred eighty children aged 1 to 10 years with SM were enrolled between 2011 and 2013 in Uganda. Kidney function was monitored daily for 4 days using serum creatinine (Cr). Acute kidney injury was defined using the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines. Blood urea nitrogen (BUN) and Cr were assessed using i-STAT, and cystatin C (CysC) was measured by enzyme-linked immunosorbent assay. Results.  Eighty-one (45.5%) children had KDIGO-defined AKI in the study: 42 (51.9%) stage 1, 18 (22.2%) stage 2, and 21 (25.9%) stage 3. Acute kidney injury evolved or developed in 50% of children after admission of hospital. There was an increased risk of AKI in children randomized to inhaled nitric oxide (iNO), with 47 (54.0%) of children in the iNO arm developing AKI compared with 34 (37.4%) in the placebo arm (relative risk, 1.36; 95% confidence interval [CI], 1.03-1.80). Duration of hospitalization increased across stages of AKI (P = .002). Acute kidney injury was associated with neurodisability at discharge in the children receiving placebo (25% in children with AKI vs 1.9% in children with no AKI, P = .002). Mortality increased across stages of AKI (P = .006) in the placebo arm, reaching 37.5% in stage 3 AKI. Acute kidney injury was not associated with neurodisability or mortality at discharge in children receiving iNO (P > .05 for both). Levels of kidney biomarkers were predictive of mortality with areas under the curves (AUCs) of 0.80 (95% CI, .65-.95; P = .006) and 0.72 (95% CI, .57-.87; P < .001), respectively. Admission levels of CysC and BUN were elevated in children who died by 6 months (P < .0001 and P = .009, respectively). Conclusions.  Acute kidney injury is an underrecognized complication in young children with SM

    Wet-cupping is an ancient medical technique still used in several contemporary societies, but little empirical study has been devoted to test its efficacy to treat tension and migraine headache. Using a pre-post research design, 70 patients with chronic tension or migraine headache were treated with wet-cupping. Three primary outcome measures were considered at the baseline and 3 months following treatment: headache severity, days of headache per month, and use of medication. Results suggest that, compared to the baseline, mean headache severity decreased by 66% following wet-cupping treatment. Treated patients also experienced the equivalent of 12.6 fewer days of headache per month. We conclude that wet-cupping leads to clinical relevant benefits for primary care patients with headache. Possible mechanisms of wet-cupping's efficacy, as well as directions for future research are discussed. PMID:18306448

    Obesity is clearly an independent risk factor for increased severity of acute pancreatitis (AP), although the mechanisms underlying this association are unknown. Adipokines (including leptin and adiponectin) are pleiotropic molecules produced by adipocytes that are important regulators of the inflammatory response. We hypothesized that the altered adipokine milieu observed in obesity contributes to the increased severity of pancreatitis. Lean (C57BL/6J), obese leptin-deficient (LepOb), and obese hyperleptinemic (LepDb) mice were subjected to AP by six hourly intraperitoneal injections of cerulein (50 microg/kg). Severity of AP was assessed by histology and by measuring pancreatic concentration of the proinflammatory cytokines IL-1beta and IL-6, the chemokine MCP-1, and the marker of neutrophil activation MPO. Both congenitally obese strains of mice developed significantly more severe AP than wild-type lean animals. Severity of AP was not solely related to adipose tissue volume: LepOb mice were heaviest; however, LepDb mice developed the most severe AP both histologically and biochemically. Circulating adiponectin concentrations inversely mirrored the severity of pancreatitis. These data demonstrate that congenitally obese mice develop more severe AP than lean animals when challenged by cerulein hyperstimulation and suggest that alteration of the adipokine milieu exacerbates the severity of AP in obesity.

    The present study aimed to investigate the immunomodulatory effects of mouse cathelicidin-related antimicrobial peptide (CRAMP) on experimental acute pancreatitis (AP). AP is a common clinical condition characterized by acute abdominal inflammation. Innate immune cells and mediators are intrinsically linked to the pathogenesis of AP. Cathelicidins are innate immunity-derived antimicrobial peptides that exert immunomodulatory effects on various host cells. However, how cathelicidins are involved and modulate the severity and inflammatory responses of AP remains unclear. In the present study, the mouse CRAMP gene-deficient cnlp−/− mice and their wild-type C57BL/6J littermates were induced with AP by multiple hourly injections of supramaximal doses of caerulein. Serum amylase levels, pancreatic myeloperoxidase activity and histological examination were performed in order to determine the disease severity and the levels of inflammatory cytokines. Disease severity and inflammatory markers were subsequently evaluated in the control mice, cnlp−/− C57BL/6J mice with AP, and wild-type C57BL/6J mice with AP. The results demonstrated that cnlp−/− mice exhibited a more severe phenotype and inflammatory response following AP induction compared with the wild-type mice, as evidenced by increased serum amylase levels, pancreatic myeloperoxidase release, and early inflammatory mediator tumor necrosis factor-α production. Histological examination confirmed that CRAMP deficiency worsened the pancreatic inflammatory condition. These results indicate that CRAMP may be considered a novel modulatory mediator in mouse experimental AP. PMID:27035328

    Abstract Experimental traumatic brain injury (TBI) studies report the neuroprotective effects of female sex steroids on multiple mechanisms of injury, with the clinical assumption that women have hormonally mediated neuroprotection because of the endogenous presence of these hormones. Other literature indicates that testosterone may exacerbate injury. Further, stress hormone abnormalities that accompany critical illness may both amplify or blunt sex steroid levels. To better understand the role of sex steroid exposure in mediating TBI, we 1) characterized temporal profiles of serum gonadal and stress hormones in a population with severe TBI during the acute phases of their injury; and 2) used a biological systems approach to evaluate these hormones as biomarkers predicting global outcome. The study population was 117 adults (28 women; 89 men) with severe TBI. Serum samples (n=536) were collected for 7 days post-TBI for cortisol, progesterone, testosterone, estradiol, luteinizing hormone (LH), and follicle-stimulating hormone (FSH). Hormone data were linked with clinical data, including acute care mortality and Glasgow Outcome Scale (GOS) scores at 6 months. Hormone levels after TBI were compared to those in healthy controls (n=14). Group based trajectory analysis (TRAJ) was used to develop temporal hormone profiles that delineate distinct subpopulations in the cohort. Structural equations models were used to determine inter-relationships between hormones and outcomes within a multivariate model. Compared to controls, acute serum hormone levels were significantly altered after severe TBI. Changes in the post-TBI adrenal response and peripheral aromatization influenced hormone TRAJ profiles and contributed to the abnormalities, including increased estradiol in men and increased testosterone in women. In addition to older age and greater injury severity, increased estradiol and testosterone levels over time were associated with increased mortality and worse global

    BACKGROUND: Diarrhea is frequently seen in developed and developing countries, and severe diarrhea is characterized by the high risk of death. Thus, it is very important to assess the severity of diarrhea early. We conducted a multi-center study to identify risk factors for the severity of diarrhea in adult patients and formulate an adult diarrhea state score (ADSS) for out-patient clinicians. METHODS: A total of 219 adult patients with acute diarrhea were divided into two groups: 132 patients with mild diarrhea and 87 with severe diarrhea. Logistic regression was used to determine risk factors for the severity of diarrhea. The risk factors were assessed and an ADSS was formulated. Receiver operating characteristic (ROC) analysis was made to evaluate the diagnostic accuracy of ADSS, and the Kappa test was used to confirm the diagnostic reliability. RESULTS: Five risk factors for evaluating the severity of diarrhea in adults included age (P<0.05), axillary temperature (P<0.01), mean arterial pressure (P<0.01), white blood cell count (WBC; P<0.01), and WBC in stool (P<0.01). The area under the ROC curve for ADSS was 0.958 when the cut off value was 4 (a sensitivity of 0.909; a specificity of 0.874), and the Kappa value was 0.781 (P<0.05). CONCLUSION: The risk factors associated with the pathogenic condition of diarrhea were identified, quantified and formulated into an ADSS, which has high diagnostic accuracy and reliability for the early identification of patients with severe acute diarrhea.

    The inter-observer agreement (reliability) and validity of a clinical asthma severity scale (ASS) derived from separate scores of wheeze, heart rate and accessory muscle use (each on a 4-point scale) were studied in 60 children aged between 6 months and 17 years (mean 5.4 years). Independent assessments of these clinical parameters were made by two paediatricians, and they also rated patients as having a mild, moderate, severe or very severe acute episode (clinical judgement rating, CJR). Oxygen saturation (SaO2) was measured concurrently by a Biox 3700 pulse oximeter and readings were categorized as mild (SaO2 greater than or equal to 94%), moderate (91-93%) and severe (less than 91%). Agreement between clinicians was assessed by the weighted kappa statistic (kappa W). Agreement for the ASS score compared to the severity grade obtained from SaO2 was slight (kappa W = 0.34) and compared to CJR the kappa W was 0.55. An ASS score of moderate or worse (greater than 3) had sensitivity of 97% and specificity of 50% for prediction of admission. The maximum frequency and duration of nebulizer therapy following admission were significantly greater for severe patients than for moderate patients. Length of hospital stay did not reflect the ASS score in the emergency department but total duration of functional disability increased with ASS score. The substitution of an adjusted heart rate score for the raw heart rate score used in ASS detracted from scale performance. The ASS is an imprecise but reasonable quantitative measure of the severity of an acute episode of asthma.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1738014

    We investigated the relationship between Chinese medicine pattern (CMP) types, their severity, and prognosis in patients (n = 187) with acute cerebral infarct (ACI). Six CMPs (wind, phlegm, fire-heat, blood stasis, qi deficiency, and yin deficiency and yang hyperactivity) were evaluated according to inspection, listening and smelling, inquiry, and palpitation. The severity and prognosis of each pattern type was determined according to the Glasgow Coma Scale (GCS), Modified Rankin Scale (MRS), National Institutes of Health Stroke Scale (NIHSS), Barthel Index (BI), and Functional Independence Measure (FIM), recorded at stroke onset and 12 weeks after stroke onset. The phlegm pattern (PP) patients displayed lower GCS, BI, and FIM scales scores, and higher MRS and NIHSS scales scores, than the nonphlegm pattern (N-PP) patients at, and 12 weeks after stroke onset, suggesting the clinical severity is greater and the prognosis is worse in PP patients with ACI than in non-PP patients with ACI.

    We report the case of a 53-year-old hemodialysis patient with severe aortic stenosis, who developed acute systemic hypoperfusion after arteriovenous fistula (AVF) construction. He presented with hypotension and repeated syncope soon after distal radiocephalic AVF construction, and finally developed a respiratory arrest. His blood pressure and hemodynamics recovered promptly by sub-emergent aortic valve replacement surgery. In the present case, the heart with severe aortic stenosis could not increase cardiac output in response to the reduction in peripheral vascular resistance caused by the AVF. High-output heart failure, a relatively rare AVF-associated disorder, occurs with an excessive AVF flow, usually more than 3 L/min or 30% of cardiac output. However, heart failure may develop soon after construction of an AVF with a moderate blood flow if a patient's cardiac function is severely impaired. In addition, heart failure may improve with AVF preservation if the underlying heart disease is treatable. PMID:21725657

We examined whether early oxandrolone treatment in severely burned adults was associated with improved outcomes during acute hospitalization. We evaluated for potential associations between oxandrolone treatment and outcomes in a large cohort of severely burned adults in the context of a multicenter observational study. Patients were dichotomized with respect to oxandrolone treatment, defined as administration within 7 days after admission, with duration of at least 7 days. Acute hospitalization outcomes were compared with univariate and multivariate analyses. One hundred seventeen patients were included in this analysis. Mean patient age was 42.6 years (range, 18–86); 77% were male, with an average TBSA of 44.1%. Baseline and injury characteristics were similar among treatment and nontreatment cohorts. Oxandrolone treatment (N =59) did not impact length of stay but was associated with a lower mortality rate (P = .01) by univariate analysis. Oxandrolone treatment was independently associated with higher survival by adjusted analyses (P = .02). Examination of early oxandrolone treatment in this cohort of severely burned adults suggests that this therapy is safe and may be associated with improved survival. Further studies are necessary to define the exact mechanisms by which oxandrolone is beneficial during inpatient treatment. PMID:18849836

    Inhaled nitric oxide (NO) causes selective pulmonary vasodilatation and may improve gas exchange. The study was aimed to evaluate the acute effects of inhaled NO on pulmonary gas exchange in severe unilateral pneumonia, where hypoxemia results from increased intrapulmonary shunt. We studied 8 patients without preexisting lung disease (59±18 yr; 4M/4F) with early unilateral severe pneumonia and respiratory failure. Pulmonary and systemic hemodynamics and gas exchange, including ventilation-perfusion (V;A/Q;) distributions, were measured at baseline and while breathing 5 and 40 parts per million (ppm) of NO. Inhaled NO caused a dose-dependent fall in pulmonary vascular resistance (by 12% and 21%, with 5 and 40ppm, respectively; p<0.01, each) and improvement of PaO2 (by 25% and 23%; p<0.05, each), owing to the reduction of intrapulmonary shunt (by 23% and 27%; p<0.05, each), without changes in the amount of perfusion to low V;A/Q; ratio alveolar units. Patients with greater baseline intrapulmonary shunt exhibited greater improvement in arterial oxygenation (r(2)=0.55, p<0.05). We conclude that low doses of inhaled NO improve pulmonary gas exchange in acute severe pneumonia. PMID:23537586

    Background Acute severe ulcerative colitis (ASUC), the most aggressive presentation ulcerative colitis (UC), occurs in 15 percent of adults and children with UC. First line therapy with intravenous corticosteroids is ineffective in half of adults and one third of children. Therapeutic monoclonal antibodies against TNF (anti-TNF therapy) are emerging as a common treatment for ASUC due to their similar efficacy to calcineurin inhibitors and more favorable adverse effect profile. Aim To comprehensively review the evidence for anti-TNF therapy for ASUC in children and adults with regard to outcomes and pharmacokinetics. Methods PubMed and recent conference proceedings were searched using the terms “ulcerative colitis”, “acute severe ulcerative colitis”, “anti-TNF”, “pharmacokinetics”, and the generic names of specific anti-TNF agents. Results Outcomes after anti-TNF therapy for ASUC remain suboptimal with aboutone half of children and adults undergoing colectomy. While several randomized controlled trials have demonstrated the efficacy of anti-TNF therapy for ambulatory patients with moderate to severely active UC, patients in these studies were less ill than those with ASUC. Patients with ASUC may exhibit more rapid clearance of anti-TNF biologics due pharmacokinetic mechanisms influenced by disease severity. Conclusions Conventional weight-based dosing effective in patients with moderately to severely active UC, may not be equally effective in those with ASUC. Personalized anti-TNF dosing strategies that integratepatient factors and early measures of pharmacokinetics and response hold promise for ensuring sustained drug exposure and maximizing early mucosal healing in patients with ASUC.

    The risk of transmission of severe acute respiratory syndrome (SARS) on airplanes is of major concern to the public and airline industry. We examined data from flights to Singapore with SARS patients on board in order to assess this risk. In-flight transmission occurred only in one of the three flights with symptomatic SARS patients on board. The incidence was estimated to be 1 out of 156 passengers. The risk of in-flight transmission of SARS appears to be far lower than that reported for influenza, but may be increased with superspreaders on board. PMID:14629772

    Cystitis is a possible adverse drug reaction associated with the use of tizanidine. Such cases have been rarely reported in literature because of the difficulty in establishing the causality. However, from a pharmacovigilance point of view, it is better to report such cases of a possible association between a drug’s use and potential adverse drug reactions. We report a case of a 26-year-old Asian female on famotidine who presented with acute severe urinary burning after taking tizanidine. PMID:26251632

    Patent applications that incorporate the genomic sequence of the severe acute respiratory syndrome (SARS) coronavirus, have been filed by a number of organizations. This is likely to result in a fragmentation of intellectual property (IP) rights which in turn may adversely affect the development of products, such as vaccines, to combat SARS. Placing these patent rights into a patent pool to be licensed on a non-exclusive basis may circumvent these difficulties and set a key precedent for the use of this form of mechanism in other areas of health care, leading to benefits to public health.

    The serum antibodies to severe acute respiratory syndrome (SARS) coronavirus of 18 SARS patients were checked at 1 month and every 3 months after disease onset. All of them except one, who missed blood sampling at 1 month, tested positive for the immunoglobulin G (IgG) antibody at 1 month. Fifteen out of 17 tested positive for the IgM antibody at 1 month. The serum IgM antibody of most patients became undetectable within 6 months after the onset of SARS. The IgG antibody of all 17 patients, whose serum was checked 1 year after disease onset, remained positive. PMID:16339072

    Many people suffering from chronic headaches use headache diaries to help track trends in their episodes. Studies have shown that electronic headache diaries are more effective than paper diaries for both patients and providers. We designed and implemented a full-size and mobile Web-based headache tracker and a database management system to store the data from the websites. The full-size website allows users to retrieve their data by viewing or downloading a table of the raw values they entered, or they can see a graphical visualization linking the severity of their headaches to any of several variables. Through this system's capacity to illustrate trends and track contributing factors for headaches, users, researchers and health service providers may gain better understanding of and control over chronic headaches.

    Intestinal barrier failure and subsequent bacterial translocation have been implicated in the development of organ dysfunction and septic complications associated with severe acute pancreatitis. Splanchnic hypoperfusion and ischemia/reperfusion injury have been postulated as a cause of increased intestinal permeability. The urinary concentration of intestinal fatty acid binding protein (IFABP) has been shown to be a sensitive marker of intestinal ischemia, with increased levels being associated with ischemia/reperfusion. The aim of the current study was to assess the relationship between excretion of IFABP in urine, gut mucosal barrier failure (intestinal hyperpermeability and systemic exposure to endotoxemia), and clinical severity. Patients with a clinical and biochemical diagnosis of acute pancreatitis were studied within 72 hours of onset of pain. Polyethylene glycol probes of 3350 kDa and 400 kDa were administered enterally, and the ratio of the percentage of retrieval of each probe after renal excretion was used as a measure of intestinal macromolecular permeability. Collected urine was also used to determine the IFABP concentration (IFABP-c) and total IFABP (IFABP-t) excreted over the 24-hour period, using an enzyme-linked immunosorbent assay technique. The systemic inflammatory response was estimated from peak 0 to 72-hour plasma C-reactive protein levels, and systemic exposure to endotoxins was measured using serum IgM endotoxin cytoplasmic antibody (EndoCAb) levels. The severity of the attack was assessed on the basis of the Atlanta criteria. Sixty-one patients with acute pancreatitis (severe in 19) and 12 healthy control subjects were studied. Compared to mild attacks, severe attacks were associated with significantly higher urinary IFABP-c (median 1092 pg/ml vs. 84 pg/ml; P < 0.001) and IFABP-t (median 1.14 microg vs. 0.21 microg; P = 0.003). Furthermore, the control group had significantly lower IFABP-c (median 37 pg/ml; P = 0.029) and IFABP-t (median

    Noninvasive positive pressure ventilation has been found to be efficacious in the setting of acute respiratory failure, specifically in chronic obstructive pulmonary disease exacerbations. Its use in congestive heart failure (CHF) is less well established. Additionally, it has been reported that there is an increase in acute myocardial infarction (AMI) rate with the use of bilevel positive pressure ventilation (BiPAP) in CHF patients. This study examined whether BiPAP decreases the intubation rate or improves cardiopulmonary parameters in severe CHF patients compared to high flow O(2) by mask (MASK), and whether there is an increase in AMI rate with the use of BiPAP. A prospective, randomized clinical trial at a county hospital teaching Emergency Department was conducted by enrolling 38 patients who were in severe CHF. Patients were randomized to receive either BiPAP or MASK in addition to adjunct therapy. Age and gender were not different between the groups. Heart rate, systolic blood pressure, diastolic blood pressure, respiratory rate, and pulse oximetry all showed no significant difference in change over time between groups, but there was a significant change over time within groups. Arterial pH, pCO(2), and pO(2) also showed no significant difference in change over time between groups, but there was a significant change over time within groups. The intubation rate for BiPAP was 23.8% (5) vs. MASK at 41.2% (7). The AMI rate was 19% (4) in the BiPAP group and 29.4% (5) in the MASK group. No true differences were detected between groups for increased oxygenation or a reduction in intubation rate. An increase in AMI rate with BiPAP was not found in this study as previously reported. This study provides support for a larger clinical trial assessing the safety and efficacy of BiPAP in acute CHF. PMID:11728761

    Objective: This study aimed to investigate the role of glucose regulated protein 78 (GRP-78) in the apoptosis of neutrophils in rats with severe acute pancreatitis. Methods: A total of 54 SD male rats were randomly assigned into 2 groups: sham group (n=24) and pancreatitis group (n=30). Severe acute pancreatitis was induced by retrograde cholangiopancreatography injection of sodium taurocholate. Rats were sacrified at 3 h, 6 h and 12 h after injection. In control group, rats received laparotomy, but the pancreates remained intact. The serum amylase was detected at different time points, and flow cytometry was done to detect the apoptosis of neutrophils. Proteins were extracted from neutrophils and subjected to detection of GRP78 and Mcl-1 expression by Western blot assay. HE staining was performed for pathological scoring of the pancreas. Results: The serum amylase in pancreatitis group increased markedly when compared with control group (P<0.01). In SAP group, the serum amylase increased gradually over time (P<0.01). HE staining showed a lot of inflammatory cells and infiltration of red blood cells and the apoptosis rate of neutrophils reduced gradually (P<0.01). Western blot assay showed the protein expression of GRP-78 and Mcl-1 increased in neutrophils over time. Conclusion: In rats with SAP, the apoptosis rate of neutrophils reduced over time, which may be associated to the stress induced expression of GRP78 and subsequent activation of Mcl-1 resulting in suppression of neutrphil apoptosis over time.

    2013-02-01

    Management of life-threatening acute severe asthma in children and adults may require anaesthetic and intensive care. The inhaled route for drug delivery is not appropriate when only small respiratory gas volumes are shifted; the i.v. route may be associated with greater side-effects. Magnesium sulphate i.v. has a place in acute asthma management because it is a mild bronchodilator, and has a stabilizing effect on the atria which may attenuate tachycardia occurring after inhaled and i.v. salbutamol. If intubation and ventilation are required, a reduction in bronchoconstriction by any means before and during these procedures should reduce morbidity. This narrative review aims to show strengths and weakness of the evidence, present controversies, and forward opinions of the author. The review contains a practical guide to the setting up, use and efficiency of nebulizers, metered dose inhalers, and spacers (chambers). It also presents a commonsense approach to the management of severe asthmatics in whom delay in bronchodilatation would cause clinical deterioration. When self-inhaled agents have had no effect, i.v. drugs may help avoid intubation and ventilation. The review includes suggestions for the use of inhaled anaesthetics, anaesthetic induction, and brief notes on subsequent ventilation of the lungs. PMID:23234642

    Severe acute respiratory syndrome coronavirus (SARS-CoV) emerged in early 2003 to cause a very severe acute respiratory syndrome, which eventually resulted in a 10% case-fatality rate. Owing to excellent public health measures that isolated focus cases and their contacts, and the use of supportive therapies, the epidemic was suppressed to the point that further cases have not appeared since 2005. However, despite intensive research since then (over 3500 publications), it remains an untreatable disease. The potential for re-emergence of the SARS-CoV or a similar virus with unknown but potentially serious consequences remains high. This is due in part to the extreme genetic variability of RNA viruses such as the coronaviruses, the many animal reservoirs that seem to be able host the SARS-CoV in which reassortment or recombination events could occur and the ability coronaviruses have to transmit relatively rapidly from species to species in a short period of time. Thus, it seems prudent to continue to explore and develop antiviral chemotherapies to treat SARS-CoV infections. To this end, the various efficacious anti-SARS-CoV therapies recently published from 2007 to 2010 are reviewed in this article. In addition, compounds that have been tested in various animal models and were found to reduce virus lung titers and/or were protective against death in lethal models of disease, or otherwise have been shown to ameliorate the effects of viral infection, are also reported.

    The pre-dietary rehabilitation levels of acute phase proteins (APP) namely, alpha-1-antitrypsin (AAT), orosomucoid (ORO), haptoglobin (HAP), fibrinogen (FIB) and C-reactive protein (CRP) in the plasma of Sudanese children with severe protein energy malnutrition (PEM) were compared with those of normal controls, and with the levels after dietary rehabilitation. Eighty one children were included in the study; 49 with severe PEM (23 with marasmus, 17 with marasmic-kwashiorkor and 9 with kwashiorkor), 13 with tuberculosis (TB) and 19 healthy children as controls. The study showed a high incidence of infections, especially acute respiratory infection (ARI), diarrhoeal diseases and intestinal parasites in the malnourished children. The mean plasma level of albumin was significantly lower in the malnourished children compared to controls (P<0.001), with kwashiorkor children showing the lowest mean level. This hypoalbuminaemia was significantly associated with the presence of ARI and intestinal parasites. The mean plasma levels of the APP, except FIB, were significantly higher in malnourished children than in controls, with higher levels associated with ARI and the presence of fever. Malnourished children with TB had significantly higher mean levels of the APP (AAT, HAP, FIB, CRP) compared to those without TB. The mean levels of HAP and AAT were significantly lower in the presence of diarrhoea, suggesting their loss in the stool. The mean levels of the APP after two weeks dietary rehabilitation and antimicrobial treatment showed a significant drop in only two of the APP, namely CRP, ORO, while FIB showed a significant rise.

    Abdominal compartment syndrome (ACS) in patients with severe acute pancreatitis (SAP) is a marker of severe disease. It occurs as combination of inflammation of retroperitoneum, visceral edema, ascites, acute peripancreatic fluid collections, paralytic ileus, and aggressive fluid resuscitation. The frequency of ACS in SAP may be rising due to more aggressive fluid resuscitation, a trend towards conservative treatment, and attempts to use a minimally invasive approach. There remains uncertainty about the most appropriate surgical technique for the treatment of ACS in SAP. Some unresolved questions remain including medical treatment, indications, timing, and interventional techniques. This review will focus on interventional treatment of this serious condition. First line therapy is conservative treatment aiming to decrease IAP and to restore organ dysfunction. If nonoperative measures are not effective, early abdominal decompression is mandatory. Midline laparostomy seems to be method of choice. Since it carries significant morbidity we need randomized studies to establish firm advantages over other described techniques. After ACS resolves efforts should be made to achieve early primary fascia closure. Additional data are necessary to resolve uncertainties regarding ideal timing and indication for operative treatment. PMID:26839539

    A novel and portable extracorporeal CO2-removal device was evaluated to provide additional gas transfer, auxiliary to standard therapy in severe acute hypercapnic respiratory failure. A dual-lumen catheter was inserted percutaneously in five subjects (mean age 55 ± 0.4 years) and, subsequently, connected to the CO2-removal device. The median duration on support was 45 hours (interquartile range 26-156), with a blood flow rate of approximately 500 mL/min. The mean PaCO2 decreased from 95.8 ± 21.9 mmHg to 63.9 ± 19.6 mmHg with the pH improving from 7.11 ± 0.1 to 7.26 ± 0.1 in the initial 4 hours of support. Three subjects were directly weaned from the CO2-removal device and mechanical ventilation, one subject was converted to ECMO and one subject died following withdrawal of support. No systemic bleeding or device complications were observed. Low-flow CO2 removal adjuvant to standard therapy was effective in steadily removing CO2, limiting the progression of acidosis in subjects with severe acute hypercapnic respiratory failure.

    Acute injuries in sport are still a problem where limited knowledge of incidence and severity in different sports at national level exists. In Sweden, 80% of the sports federations have their mandatory injury insurance for all athletes in the same insurance company and injury data are systematically kept in a national database. The aim of the study was to identify high-risk sports with respect to incidence of acute and severe injuries in 35 sports reported to the database. The number and incidences of injuries as well as injuries leading to permanent medical impairment (PMI) were calculated during 2008-2011. Each year approximately 12,000 injuries and 1,162,660 licensed athletes were eligible for analysis. Eighty-five percent of the injuries were reported in football, ice hockey, floorball, and handball. The highest injury incidence as well as PMI was in motorcycle, handball, skating, and ice hockey. Females had higher risk of a PMI compared with males in automobile sport, handball, floorball, and football. High-risk sports with numerous injuries and high incidence of PMI injuries were motorcycle, handball, ice hockey, football, floorball, and automobile sports. Thus, these sports ought to be the target of preventive actions at national level. PMID:25850826

    Severe acute respiratory syndrome (SARS) is characterized by a risk of nosocomial transmission; however, the risk of airborne transmission of SARS is unknown. During the Toronto outbreaks of SARS, we investigated environmental contamination in SARS units, by employing novel air sampling and conventional surface swabbing. Two polymerase chain reaction (PCR)-positive air samples were obtained from a room occupied by a patient with SARS, indicating the presence of the virus in the air of the room. In addition, several PCR-positive swab samples were recovered from frequently touched surfaces in rooms occupied by patients with SARS (a bed table and a television remote control) and in a nurses' station used by staff (a medication refrigerator door). These data provide the first experimental confirmation of viral aerosol generation by a patient with SARS, indicating the possibility of airborne droplet transmission, which emphasizes the need for adequate respiratory protection, as well as for strict surface hygiene practices.

    Medication-overuse headache (MOH) is a debilitating condition in which frequent and prolonged use of medication for the acute treatment of pain results in the worsening of the headache. The purpose of this paper is to review the most recent literature on MOH and discuss future avenues for research. MOH accounts for a substantial share of the global burden of disease. Prevalence is often reported as 1–2% but can be as high as 7% overall, with higher proportions among women and in those with a low socioeconomic position. Management consists of withdrawing pain medication, focusing on prophylactic and nonmedical treatments, and limiting acute symptomatic medication. Stress reduction and lifestyle interventions may support the change towards rational pain medication use. Support, follow up, and education are needed to help patients through the detoxification period. There is fertile ground for research in MOH epidemiology, pathophysiology, and neuroimaging. Randomized and long-term follow-up studies on MOH treatment protocols are needed. Further focused research could be of major importance for global health. PMID:27493718

    Background Respiratory syncytial virus (RSV) and influenza A viruses are known to cause severe acute respiratory tract infections (SARIs) in children. For other viruses like human rhinoviruses (HRVs) this is less well established. Viral or bacterial co-infections are often considered essential for severe manifestations of these virus infections. Objective The study aims at identifying viruses that may cause SARI in children in the absence of viral and bacterial co-infections, at identifying disease characteristics associated with these single virus infections, and at identifying a possible correlation between viral loads and disease severities. Study Design Between April 2007 and March 2012, we identified children (<18 year) with or without a medical history, admitted to our paediatric intensive care unit (PICU) with SARI or to the medium care (MC) with an acute respiratory tract infection (ARTI) (controls). Data were extracted from the clinical and laboratory databases of our tertiary care paediatric hospital. Patient specimens were tested for fifteen respiratory viruses with real-time reverse transcriptase PCR assays and we selected patients with a single virus infection only. Typical bacterial co-infections were considered unlikely to have contributed to the PICU or MC admission based on C-reactive protein-levels or bacteriological test results if performed. Results We identified 44 patients admitted to PICU with SARI and 40 patients admitted to MC with ARTI. Twelve viruses were associated with SARI, ten of which were also associated with ARTI in the absence of typical bacterial and viral co-infections, with RSV and HRV being the most frequent causes. Viral loads were not different between PICU-SARI patients and MC-ARTI patients. Conclusion Both SARI and ARTI may be caused by single viral pathogens in previously healthy children as well as in children with a medical history. No relationship between viral load and disease severity was identified. PMID:26964038

    Acute lung injury (ALI) is a critical complication of the severe acute pancreatitis (SAP), characterized by increased pulmonary permeability with high mortality. Pulmonary microvascular endothelial cells (PMVECs) injury and apoptosis play a key role in ALI. Previous studies indicated that store-operated calcium entry (SOCE) could regulate a variety of cellular processes. The present study was to investigate the effects of SOCE inhibition on ALI induced by SAP in Sprague-Dawley rats, and PMVECs injury induced by lipopolysaccharide (LPS). Rat model of SAP-associated ALI were established by the retrograde infusion of sodium deoxycholate. Serum levels of amylase, TNF-α, and IL-6, histological changes, water content of the lung, oxygenation index, and ultrastructural changes of PMVECs were examined in ALI rats with or without store-operated Ca(2+) channels (SOCs) pharmacological inhibitor (2-aminoethoxydiphenyl borate, 2-APB) pretreatment. For in vitro studies, PMVECs were transiently transfected with or without small interfering RNA (siRNA) against calcium release-activated calcium channel protein1 (Orai1) and stromal interaction molecule1 (STIM1), the two main molecular constituents of SOCs, then exposed to LPS. The viability of PMVECs was determined. The expression of STIM1, Orai1, Bax, and caspase3, both in lung tissue and in PMVECs, were assessed by quantitative real-time PCR and western blot. Administration of sodium deoxycholate upregulated the expression of SOCs proteins in lung tissue. Similarly, the SOCs proteins were increased in PMVECs induced by LPS. 2-APB reduced the serum levels of amylase, TNF-α, and IL-6, and attenuated lung water content and histological findings. In addition, the decreased oxygenation index and ultrastructural damage in PMVECs associated with SAP were ameliorated after administration of 2-APB. Knockdown of STIM1 and Orai1 inhibited LPS-induced PMVECs death. Furthermore, blockade of SOCE significantly suppressed Orai1, STIM1, Bax

    The therapeutic procedures of cluster headache begin from the precise diagnose. Because cluster headache is usually accompanied with teeth pain and/or neck pain, some patients aren't able to consult adequate medical institutions. In this lecture I showed the some male and female patients as examples. The female patient was suffered from menstruation related migraine in her period of cluster headache. From the view point of treatment, preventive medicines are essential. They not just reduce severity and also improve the length of headache-period. Suitable preventive medicines may avoid the whole severe attacks. We reported therapeutic experiences of valproate, gabapentin and amitriptyline with verapamil in 2010 at general meeting of Societas Neurologica Japonica. Steroids are not indispensable. As for triptans rapid-type one are usually used. If the attacks are severe, sumatriptan subcutaneous injection kit (SSI) needs to be introduced. The expert nurses who are skilled in the procedures of SSI improve both patients' adherence and therapeutic efficiency. We held a first educational meeting of SSI in Tokyo 2012. Because cluster headache is formidable, the integrated therapy which is composed of precise diagnosis, preventive medicine and adequate medicines for headache attacks is essential and needed.

    Pain has been considered as part of a defensive strategy whose specific role is to signal an immediate active danger to the organism. This definition fits well for acute pain. It does not work well, however, for chronic pain that is maintained even in absence of an ongoing, active threat. Currently, acute and chronic pain are considered to be separate conditions. What follows is a review of the different theories about pain and its history. Different hypotheses regarding pain mechanisms are illustrated. New data emerging from scientific research on chronic pain (migraine in particular) involving innovative imaging techniques are reported and discussed. PMID:23030540

    The purpose of the present study was to investigate the effectiveness of acute phase hybrid assistive limb (HAL) rehabilitation training for patients after stroke by measuring the difference in the severity of paralysis. Fifty-three acute stroke patients were enrolled in this prospective cohort study. HAL training was administered about twice per week, and the mean number of sessions was 3.9 ± 2.7. The walking training was performed on a treadmill with individually adjustable body weight support and speed and there was a 10-m walk test (10MWT) before and after each session. Assessment at baseline and at endpoint consisted of the Glasgow Coma Scale (GCS), Revised Hasegawa’s Dementia Scale (HDS-R), Brunnstrom stage (Brs), Functional Independence Measure (FIM), Barthel index (BI), and 10MWT. We measured these assessments at the first walking training session and at the end of the final training session without the HAL. To evaluate the feasibility of training with the HAL, the outcome measures of BI, FIM, and speed and number of steps of 10MWT were compared before and after training using a paired Wilcoxon’s signed-rank test in different Brs. Except for Brs IV, the Brs III or higher subgroups displayed significant amelioration in BI, and the Brs III subgroup displayed significant amelioration in FIM. The Brs V and VI subgroups displayed significant amelioration in 10-m walking speed and steps. In acute phase rehabilitation after stroke, it is thought that the HAL is more effective for patients with less lower-limb paralysis, such as Brs III or higher. PMID:26041627

    Background and objectives: Serum creatinine concentration at the time of nephrology consultation is not necessarily indicative of the severity of acute kidney injury (AKI). Although urine microscopy is useful to differentiate AKI, its role in predicting adverse clinical outcomes has not been well described. Design, setting, participants, & measurements: The relationship between urine microscopy findings at the time of nephrology consultation for AKI and clinical outcomes was evaluated prospectively. A urinary sediment scoring system was created on the basis of the number of renal tubular epithelial cells and granular casts. The primary outcome was worsening of AKI (progressing to higher AKI Network stage, dialysis, or death) during hospitalization. Results: Of 249 patients consulted for AKI, 197 had acute tubular necrosis or prerenal AKI and were included in the analysis. At consultation, 80 (40%) had stage 1, 53 (27%) had stage 2, and 66 (33%) had stage 3 AKI. The urinary sediment combined scores were lowest in those with stage 1 and highest in stage 3 AKI. Seventy-nine patients (40%) experienced worsening of AKI from the time of consultation. The urinary scoring system was significantly associated with increased risk of worsening AKI (adjusted relative risk: 7.3; 95% confidence interval: 4.5 to 9.7 for worsening with score of ≥3 versus score of 0) and was more predictive than AKI Network stage at the time of consultation. Conclusions: The urinary sediment score may be a useful tool to predict worsening of AKI due to either acute tubular necrosis or prerenal AKI during hospitalization. PMID:20089493

    Objectives: Dopaminergic signaling is implicated in nociceptive pathways. These effects are mediated largely through dopamine receptors and modulated in part by dopamine transporters. This study tests the hypothesis that genetic variants in the genes encoding dopamine receptor 2 (DRD2) and the dopamine active transporter (SLC6A3) influence acute pain severity after motor vehicle collision (MVC). Methods: European Americans presenting to the emergency department (ED) after MVC were recruited. Overall pain intensity in ED was assessed using a 0-10 numeric rating scale. DNA was extracted from blood samples and genotyping of single nucleotide polymorphisms (SNPs) in the DRD2 and SLC6A3 gene was performed. Results: A total of 948 patients completed evaluation. After correction for multiple comparisons, SNP rs6276 at DRD2 showed significant association with pain scores, with individuals with the A/A genotype reporting lower mean pain scores (5.3, 95% CI 5.1 to 5.5) than those with A/G (5.9, 95% CI 5.6 to 6.1) or G/G (5.7, 95%CI 5.2 to 6.2) genotypes (p=0.0027). Secondary analyses revealed an interaction between sex and DRD2 SNPs rs4586205 and rs4648318 on pain scores: females with two minor alleles had increased pain intensity, whereas males with two minor alleles had less pain than individuals with a major allele (interaction p=0.0019). Discussion: Genetic variants in DRD2 are associated with acute pain after a traumatic stressful event. These results suggest that dopaminergic agents may be useful for the treatment of individuals with acute post-traumatic pain as part of a multimodal opioid-sparing analgesic regimen. PMID:25370144

Since most cases of head pain are associated with few or inconstant physical signs, the key to an accurate diagnosis lies largely in a careful, systematic history. This article provides a scheme by which the busy optometric clinician can expeditiously obtain an incisive and relevant profile of every headache patient, and thereby determine the appropriate mode of management, and referral.

    Systemic lupus erythematosus (SLE) is an autoimmune disease characterized with multiple organ involvements. Acute acalculous cholecystitis(AAC) is an extremely rare manifestation of digestive system involvement in SLE. We reported a case of 32-year-old woman who complained skin rashes for two weeks and stomachache and oliguria for one day. She had rashes at onset, and developed fever, stomachache, hypotension and headache. Physical examination at admission indicated blood pressure 76/47 mmHg(1 mmHg=0.133 kPa), heart rate 107 beats/min, warm acra. Murphy's sign was positive. Ultrasound suggested the enlarged gallbladder with surrounding hypoecho band yet no biliary calculi were found. A diagnosis of SLE was made, characteristic with distributive shock at the onset and AAC, complicated with neuropsychiatric lupus and lupus nephritis. She had an acute and severe course of disease, which had been relieved after treatment of high dose glucocorticoid and immunosuppressants. This case arouses clinicians to pay more attention to AAC as a rare form of disease flare in SLE. Early diagnosis of AAC is crucial to a favorable prognosis and in avoid of abdominal surgery.

    Objectives To identify the viral aetiology in adult patients with severe acute respiratory infection (SARI) admitted to sentinel surveillance institutions in Bogotá in 2012. Design A cross-sectional study was conducted in which microarray molecular techniques for viral identification were used on nasopharyngeal samples of adult patients submitted to the surveillance system, and further descriptions of clinical features and relevant clinical outcomes, such as mortality, need for critical care, use of mechanical ventilation and hospital stay, were obtained. Setting Respiratory infections requiring hospital admission in surveillance centres in Bogotá, Colombia. Participants Ninety-one adult patients with acute respiratory infection (55% were female). Measurements Viral identification, intensive care unit admission, hospital stay, and mortality. Results Viral identification was achieved for 63 patients (69.2%). Comorbidity was frequently identified and mainly involved chronic pulmonary disease or pregnancy. Influenza, Bocavirus and Adenovirus were identified in 30.8%, 28.6% and 18.7% of the cases, respectively. Admission to the intensive care unit occurred in 42.9% of the cases, while mechanical ventilation was required for 36.3%. The average hospital stay was 9.9 days, and mortality was 15.4%. Antibiotics were empirically used in 90.1% of patients. Conclusions The prevalence of viral aetiology of SARI in this study was high, with adverse clinical outcomes, intensive care requirements and high mortality. PMID:26576054

    Acute exogenous lipoid pneumonia is a rare disorder in adults. A treatment of choice for lipoid pneumonia has not been established, and systemic corticosteroid use remains controversial. We report the case of a 32-year-old man with schizophrenia who presented with kerosene-induced acute exogenous lipoid pneumonia that was treated with a systemic corticosteroid. In this case, supportive therapy did not improve the patient's condition, so systemic corticosteroid therapy was commenced four days after he ingested the kerosene. After corticosteroid commencement, the patient's symptoms and hypoxia improved within a few days. Although some radiological characteristics of this disorder have been reported previously, the process of radiological improvement of exogenous lipoid pneumonia is not well known. In this case, computed tomography findings changed dramatically after corticosteroid therapy was initiated. Extensive bilateral consolidations that were observed on admission improved. Although pneumatoceles developed two weeks after corticosteroid commencement, they were nearly gone after two months of the treatment. While corticosteroid therapy is not suitable for all cases, it should be considered for severe or refractory cases. PMID:27222789

    We report herein on a case of severe Japanese spotted fever complicated by acute respiratory failure in Kobe City. A 70-year-old female presenting with general malaise and systematic erythema was admitted to our hospital in June, 2013. From her history and physical examination, she was found to be suffering from scleroderma and mild interstitial pneumonia. From admission, the patient was noted to have a fever of 39 degrees C accompanied by relative bradycardia. Physical examination revealed a black eschar on her right leg, making us suspect rickettsial infection since Kobe City is not an area predisposed to Japanese spotted fever. Three days after admission, her condition worsened and treatment with minocycline and levofloxacin was initiated in accordance with the treatment protocol for Japanese spotted fever. The following day, the patient developed acute respiratory distress syndrome (ARDS) and was put on a respirator. She gradually recovered with the antibiotic treatment and was discharged from the hospital 23 days after admission. The diagnosis of Japanese spotted fever was confirmed by conducting a polymerase chain reaction test on the eschar. Japanese spotted fever is noted to occur in any place other than Kobe City. Late diagnoses may result in aggravated cases of Japanese spotted fever, with the possibility of developing ARDS as a complication. PMID:27197438

    Background Comorbidities have a serious impact on the frequent severe acute exacerbations (AEs) in patients with COPD. Previous studies have used the Charlson comorbidity index to represent a conglomerate of comorbidities; however, the respective contribution of each coexisting disease to the frequent severe AEs remains unclear. Methods A retrospective, observational study was performed in 77 COPD patients who experienced severe AE between January 2012 and December 2014 and had at least 1-year follow-up period from the date of admission for severe AE. We explored the incidence of frequent severe AEs (≥2 severe AEs during 1-year period) in these patients and investigated COPD-related factors and comorbidities as potential risk factors of these exacerbations. Results Out of 77 patients, 61 patients (79.2%) had at least one comorbidity. During a 1-year follow-up period, 29 patients (37.7%) experienced frequent severe AEs, approximately two-thirds (n=19) of which occurred within the first 90 days after admission. Compared with patients not experiencing frequent severe AEs, these patients were more likely to have poor lung function and receive home oxygen therapy and long-term oral steroids. In multiple logistic regression analysis, coexisting asthma (adjusted odds ratio [OR] =4.02, 95% confidence interval [CI] =1.30–12.46, P=0.016), home oxygen therapy (adjusted OR =9.39, 95% CI =1.60–55.30, P=0.013), and C-reactive protein (adjusted OR =1.09, 95% CI =1.01–1.19, P=0.036) were associated with frequent severe AEs. In addition, poor lung function, as measured by forced expiratory volume in 1 second (adjusted OR =0.16, 95% CI =0.04–0.70, P=0.015), was inversely associated with early (ie, within 90 days of admission) frequent severe AEs. Conclusion Based on our study, among COPD-related comorbidities, coexisting asthma has a significant impact on the frequent severe AEs in COPD patients. PMID:27536097

    Background Cluster headache (CH) is a neurovascular, primary headache disorder. There are, however, several case reports about patients whose CH started shortly after a structural brain disease or trauma. Motivated by a patient who developed CH 3 weeks after the removal of an eye and by similar case reports, we tested the hypothesis that the removal of an eye is a risk factor for CH. Methods A detailed headache questionnaire was filled out by 112 patients on average 8 years after enucleation or evisceration of an eye. Results While 21 % of these patients experienced previously unknown headaches after the removal of an eye, no patient fulfilled the diagnostic criteria for CH. Conclusion Our data does not suggest that the removal of an eye is a major risk factor for the development of CH. PMID:15784136

    This study presents six cases of headache that appeared only during flights and was not associated with other headache forms. The cases had severe headache attacks during some flights, when the plane was landing and taking off, with a unilateral and generally orbital and/or supraorbital localization. The attacks lasted between 15 and 20 min on average and recovered spontaneously, without any accompanying sign. We think that barotrauma caused by pressure changes in the cabin during take-off and landing could affect ethmoidal nerves (branching from the ophthalmic branch of the trigeminal nerve) that carry the senses of the mucosa on the inner surface of the paranasal sinuses, and/or nociceptors in ethmoidal arteries, thereby activating the trigeminovascular system and leading to headache.

    The traffic control bundle consists of procedures designed to help prevent epidemic nosocomial infection. We retrospectively studied the serial infection control measures to determine factors most effective in preventing nosocomial infections of healthcare workers (HCWs) during the 2003 Taiwanese severe acute respiratory syndrome (SARS) epidemic. Fever screening stations, triage of fever patients, separating SARS patients from other patients, separation of entrances and passageways between patients and HCWs, and increasing hand-washing facilities all demonstrated a protective effect for HCWs (univariate analysis; P<0.05). By multiple logistic regression: (i) checkpoint alcohol dispensers for glove-on hand rubbing between zones of risk, and (ii) fever screening at the fever screen station outside the emergency department, were the significant methods effectively minimising nosocomial SARS infection of HCWs (P<0.05). The traffic control bundle should be implemented in future epidemics as a tool to achieve strict infection control measures. PMID:21316802

    γ-Butyrolactone (GBL) is a popular drug of abuse which is easily available over the internet. Following a UK classification change to a class C drug in January 2010, internet supply has become difficult. Some of the effects have resulted in sourcing GBL from industrial solvents. We report a case of a 24-year-old man who was admitted for detoxification from GBL. He reported having sourced the GBL by diluting the contents of nail varnish remover pads with water. During his admission he developed a severe withdrawal delirium and acute renal failure. He required admission to the intensive care unit. Physicians and psychiatrists should be aware of toxic sources of GBL leading to renal failure and consider GBL in those presenting with agitation, psychosis or coma. PMID:21454980

    Immune-checkpoint inhibitors are emerging as revolutionary drugs for certain malignancies. However, blocking the co-inhibitory signals may lead to immune-related adverse events, mainly in the spectrum of autoimmune diseases including colitis, endocrinopathies and nephritis. Here, we report a case of a 75-year-old man with metastatic malignant melanoma treated with a combination of nivolumab (anti-PD1-antibody) and ipilimumab (anti-CTLA-4 antibody) who developed systemic rash along with severe acute tubulointerstitial nephritis after two doses of combination therapy. Kidney biopsy and peripheral blood immune profile revealed highly proliferative and cytotoxic T cell features.

    OBJECTIVE: To map risk of exposure to severe acute respiratory syndrome (SARS) in an urban area and assess the ability of traditional interventions to control dispersion of the disease. METHODS: Data on the Beijing SARS epidemic were used to map spatial clusters of identified contacts and to estimate transmission of SARS using a model with a time-dependent transmission rate. RESULTS: The estimated transmission rate decreased dramatically from 20 to 30 April 2003. The total number of cases in the epidemic in Beijing was estimated to be 2521. Hierarchical clustering revealed that risk-exposures were widespread, but clustered in a pattern that is distinctly related to the Beijing urban ring roads. CONCLUSION: Traditional control measures can be very effective at reducing transmission of SARS. Spatial patterns of risk-exposures can inform disease surveillance, prediction and control by identifying spatial target areas on which interventions should be focused. PMID:17242832

    It is 10 years since severe acute respiratory syndrome (SARS) emerged, and East and Southeast Asia retain a reputation as a hot spot of emerging infectious diseases. The region is certainly a hot spot of socioeconomic and environmental change, and although some changes (e.g., urbanization and agricultural intensification) may reduce the probability of emerging infectious diseases, the effect of any individual emergence event may be increased by the greater concentration and connectivity of livestock, persons, and products. The region is now better able to detect and respond to emerging infectious diseases than it was a decade ago, but the tools and methods to produce sufficiently refined assessments of the risks of disease emergence are still lacking. Given the continued scale and pace of change in East and Southeast Asia, it is vital that capabilities for predicting, identifying, and controlling biologic threats do not stagnate as the memory of SARS fades.

    System dynamics approach offers great potential for addressing how intervention policies can affect the spread of emerging infectious diseases in complex and highly networked systems. Here, we develop a model that explains the severe acute respiratory syndrome coronavirus (SARS-CoV) epidemic that occurred in Hong Kong in 2003. The dynamic model developed with system dynamics methodology included 23 variables (five states, four flows, eight auxiliary variables, six parameters), five differential equations and 12 algebraic equations. The parameters were optimized following an iterative process of simulation to fit the real data from the epidemics. Univariate and multivariate sensitivity analyses were performed to determine the reliability of the model. In addition, we discuss how further testing using this model can inform community interventions to reduce the risk in current and future outbreaks, such as the recently Middle East respiratory syndrome coronavirus (MERS-CoV) epidemic.

    Tet is a type of alkaloid extracted from Stephania tetrandra, and it has recently been demonstrated that Tet can protect against inflammation and free radical injury and inhibit the release of inflammatory mediators. The present study was designed to observe the protective effect of Tet on sodium taurocholate-induced severe acute pancreatitis (SAP). The rat model of SAP was induced by retrograde bile duct injection of sodium taurocholate and then treated with Verapamil and Tet. The results showed that Tet can reduce NF-κB activation in pancreas issue, inhibit the SAP cascade, and improve SAP through inducing pancreas acinar cell apoptosis and stabilizing intracellular calcium in the pancreas, thus mitigating the damage to the pancreas. Our study revealed that Tet may reduce systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndromes (MODS) to protect against damage, and these roles may be mediated through the NF-κB pathway to improve the proinflammatory/anti-inflammatory imbalance.

    Immune-checkpoint inhibitors are emerging as revolutionary drugs for certain malignancies. However, blocking the co-inhibitory signals may lead to immune-related adverse events, mainly in the spectrum of autoimmune diseases including colitis, endocrinopathies and nephritis. Here, we report a case of a 75-year-old man with metastatic malignant melanoma treated with a combination of nivolumab (anti-PD1-antibody) and ipilimumab (anti-CTLA-4 antibody) who developed systemic rash along with severe acute tubulointerstitial nephritis after two doses of combination therapy. Kidney biopsy and peripheral blood immune profile revealed highly proliferative and cytotoxic T cell features. Herein, we discuss the pathophysiology and management of immune checkpoint blockade-related adverse events. PMID:27274826

    Study on the action mechanism of inflammatory mediators generated by the severe acute pancreatitis (SAP) in multiple organ injury is a hotspot in the surgical field. In clinical practice, the main complicated organ dysfunctions are shock, respiratory failure, renal failure, encephalopathy, with the rate of hepatic diseases being closely next to them. The hepatic injury caused by SAP cannot only aggravate the state of pancreatitis, but also develop into hepatic failure and cause patient death. Its complicated pathogenic mechanism is an obstacle in clinical treatment. Among many pathogenic factors, the changes of vasoactive substances, participation of inflammatory mediators as well as OFR (oxygen free radical), endotoxin, etc. may play important roles in its progression.

    Background Several countries have established or are planning acute psychiatric in-patient services that accept around-the-clock emergency admission of adolescents. Our aim was to investigate the characteristics and clinical outcomes of a cohort of patients at four Norwegian units. Methods We used a prospective pre-post observational design. Four units implemented a clinician-rated outcome measure, the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA), which measures mental health problems and their severity. We collected also data about the diagnoses, suicidal problems, family situations, and the involvement of the Child Protection Service. Predictions of outcome (change in HoNOSCA total score) were analysed with a regression model. Results The sample comprised 192 adolescents admitted during one year (response rate 87%). Mean age was 15.7 years (range 10-18) and 70% were girls. Fifty-eight per cent had suicidal problems at intake and the mean intake HoNOSCA total score was 18.5 (SD 6.4). The largest groups of main diagnostic conditions were affective (28%) and externalizing (26%) disorders. Diagnoses and other patient characteristics at intake did not differ between units. Clinical psychiatric disorders and developmental disorders were associated with severity (on HoNOSCA) at intake but not with outcome. Of adolescents ≥ 16 years, 33% were compulsorily admitted. Median length of stay was 8.5 days and 75% of patients stayed less than a month. Compulsory admissions and length of stay varied between units. Mean change (improvement) in the HoNOSCA total score was 5.1 (SD 6.2), with considerable variation between units. Mean discharge score was close to the often-reported outpatient level, and self-injury and emotional symptoms were the most reduced symptoms during the stay. In a regression model, unit, high HoNOSCA total score at intake, or involvement of the Child Protection Service predicted improvement during admission. Conclusions Acute

    Headache is the most frequent neurological symptom and the most prevalent pain in children and adolescents, and constitutes a serious health problem that may lead to impairment in several areas. Psychosocial factors, social environment, life events, school and family stressors are all closely related to headaches. A multidisciplinary strategy is fundamental in addressing headache in children and adolescents. Applying such a strategy can lead to reductions in frequency and severity of the pain, improving significantly the quality of life of these children.It has been demonstrated that behavioral intervention is highly effective, especially in the treatment of paediatric headache, and can enhance or replace pharmacotherapy, with the advantage of eliminating dangerous side effects and or reducing costs. Behavioral interventions appear to maximize long-term therapeutic benefits and improve compliance with pharmacological treatment, which has proven a significant problem with child and adolescent with headache.The goal of this review is to examine the existing literature on behavioral therapies used to treat headache in children and adolescents, and so provide an up-to-date picture of what behavioral therapy is and what its effectiveness is.

    Severity of acute respiratory infection is higher in developing countries, especially among the socioeconomically underprivileged. Viral pneumonias are more common, especially among children. A prospective hospital-based case control study was undertaken in Bogota between November 2000 and August 2001, aimed to identify factors related to severe low acute respiratory infection (SLARI). Cases were limited to children aged between 2 months and 5 years who filled WHO criteria for SLARI. Controls were children at the same hospital with ARI in a similar age range, but without symptoms of chest drawing. A total of 638 children (277 cases and 361 controls) were included. The most important risk factors included the following: living in borrowed houses (odds ratio (OR) = 2.7; 95% Confidence Interval (CI): 1.06-7.07), sharing the bed (OR = 1.88, CI: 1.0-3.7), living with more than 9 people (OR = 1.82, CI: 1.0-3.51), and living with smokers (OR = 1.4, CI: 1.0-2.05). Of the 114 samples collected (from children at third day after beginning of symptoms), 98 had viruses, sincitial respiratory virus was the most frequently identified virus (41.8%), followed by influenza A virus (3.1%) and influenza B virus (1%). All positive isolates for influenza A and B were sent to the United States Center for Disease Control (CDC) in Atlanta, where they were classified as influenza A/PANAMA/2007/99-like and influenza B/SICHUAN/379/99-like, respectively.

    Mushroom-related poisoning can cause acute kidney injury. Here we report a case of acute kidney injury after ingestion of Amanita punctata, which is considered an edible mushroom. Gastrointestinal symptoms occurred within 24 hours from the mushroom intake and were followed by an asymptomatic period, acute kidney injury, and elevation of liver and pancreatic enzymes. Kidney function recovered with supportive care. Nephrotoxic mushroom poisoning should be considered as a cause of acute kidney injury. PMID:26779427

    The coronavirus (CoV) responsible for severe acute respiratory syndrome (SARS), SARS-CoV, encodes two large polyproteins (pp1a and pp1ab) that are processed by two viral proteases to yield mature non-structural proteins (nsps). Many of these nsps have essential roles in viral replication, but several have no assigned function and possess amino acid sequences that are unique to the CoV family. One such protein is SARS-CoV nsp1, which is processed from the N-terminus of both pp1a and pp1ab. The mature SARS-CoV protein is present in cells several hours post-infection and co-localizes to the viral replication complex, but its function in the viral life cycle remains unknown. Furthermore, nsp1 sequences are highly divergent across the CoV family, and it has been suggested that this is due to nsp1 possessing a function specific to viral interactions with its host cell or acting as a host specific virulence factor. In order to initiate structural and biophysical studies of SARS-CoV nsp1, a recombinant expression system and a purification protocol have been developed, yielding milligram quantities of highly purified SARS-CoV nsp1. The purified protein was characterized using circular dichroism, size exclusion chromatography, and multi-angle light scattering. PMID:17187987

    The objectives of this article are to describe the severe acute respiratory illness (SARI) surveillance implemented in Louisiana during the 2013-2014 influenza season, present the epidemiology of reported SARI cases, and identify ways to improve this system by incorporating formal SARI surveillance into the influenza surveillance program. Of the 212 SARI cases, 181 (85%) had at least one underlying medical condition, 54 (25.7%) had two conditions, 43 (20.3%) had three conditions, and 25 (11.8%) reported four or more. The most common four underlying conditions were: obesity (43.4%), chronic cardiac conditions (39.6%), diabetes (29.7%), and chronic pulmonary conditions (26.9%). While obesity was the most reported underlying condition, it was three times more likely to be reported in less than 65 years old rather than those >65. Continuation of SARI data collection in future seasons will allow comparisons regarding severity, populations affected, and identify risk factors most commonly associated with severe illness. Reporting of SARI cases also increased influenza-associated adult mortality reporting to the Office of Public Health's Office of Infectious Diseases Epidemiology (ID Epi). Though all influenza-associated mortality is reportable in Louisiana, adult mortality was reported rarely prior to the 2013-2014 season. PMID:27159455

    The severe acute respiratory syndrome (SARS) coronavirus encodes several RNA-processing enzymes that are unusual for RNA viruses, including Nsp15 (nonstructural protein 15), a hexameric endoribonuclease that preferentially cleaves 3' of uridines. We solved the structure of a catalytically inactive mutant version of Nsp15, which was crystallized as a hexamer. The structure contains unreported flexibility in the active site of each subunit. Substitutions in the active site residues serine 293 and proline 343 allowed Nsp15 to cleave at cytidylate, whereas mutation of leucine 345 rendered Nsp15 able to cleave at purines as well as pyrimidines. Mutations that targeted the residues involved in subunit interactions generally resulted in the formation of catalytically inactive monomers. The RNA-binding residues were mapped by a method linking reversible cross-linking, RNA affinity purification, and peptide fingerprinting. Alanine substitution of several residues in the RNA-contacting portion of Nsp15 did not affect hexamer formation but decreased the affinity of RNA binding and reduced endonuclease activity. This suggests a model for Nsp15 hexamer interaction with RNA.

    To evaluate the patterns of renal images and the diagnostic value as a screening test of the whole-body bone and renal scintigraphy with technetium-99m-methylene diphosphonate (99mTc-MDP) or -pyrophosphate (99mTc-PYP), we performed bone scintigraphy in 6 patients with acute renal failure (ARF) with severe loin pain and patchy renal vasoconstriction on postcontrast renal computed tomography (CT). All 6 patients were young and previously healthy but experienced severe loin pain after track events. Five took analgesics. Postcontrast renal CT showed patchy low-density areas or diffuse enhancement immediately after radiocontrast injection and then patchy wedge-shaped enhancement 24 or 48 h later, which subsequently disappeared 72 h later. On the whole-body bone scintigrams with 99mTc-MDP or 99mTc-PYP before obtaining renal CT, there was no increased uptake of isotope in the soft tissue, and multiple patchy increased accumulations of the isotope in the kidney were observed in 5 patients. In 2 patients, renal scintigraphies with technetium-99m-dimercaptosuccinate showed photon-deficient areas in the same areas of patchy isotope accumulation in the whole-body bone scintigraphies. Whole-body image and renal scintigraphy with bone-seeking agents may be useful as a screening test and in the search for the theoretical evidence of ARF with severe loin pain and patchy renal vasoconstriction.

    Severe sepsis still remains a major cause of morbidity and mortality, claiming between 36,000 to 64,000 lives annually in the UK, with a mortality rate of 35%.[1,2] The project aims to measure the management of severely septic patients in acute medical unit (AMU) in a district general hospital against best practice guidelines, before and after a set of interventions aiming to optimise patient management and outcomes. All new admissions who met the criteria for sepsis in AMU over a two week period were evaluated. Those who met the criteria for severe sepsis were further analysed. The criteria evaluated were time to first administration of oxygen, intravenous fluids, antibiotics, the taking of blood cultures, other relevant bloods tests (including lactate) and urine output monitoring. A re-audit was completed after the introduction of a set of interventions which included a “sepsis box.” A total of 32 patients (19 Males, 13 Females) were identified in the pre-intervention group. Twenty-two of these patients met the criteria for severe sepsis. Only 15 out of 32 (47%) had their lactate measured. Ten out of 22 (45%) received fluids within an hour. Twelve out of 22 (55%) had their blood culture sample taken after administration of antibiotics and only 12 out of 22 (55%) had antibiotics administrated within an hour of medical assessment. Post-intervention the results however improved dramatically. A total of 30 patients were identified in the post-intervention group (12 Males, 18 Females). Antibiotics administration within an hour went up by 22%. Lactate was performed in 26/30 (87%) patients presented with sepsis compared to 47% in the pre-intervention group. Similarly, identification of severe sepsis, and administration of intravenous fluids also showed improvement ultimately improving patient safety. Following the initial success, the trial was repeated over three months period, which showed sustainable improvement. PMID:26734299

    Sepsis accounts for 80% of deaths from acute pancreatitis. This study aimed to investigate early changes in intestinal permeability in patients with acute pancreatitis, and to correlate these changes with subsequent disease severity and endotoxemia. The renal excretion of enterally administered polyethylene glycol (PEG) 3350 and PEG 400 was measured within 72 hours of onset of acute pancreatitis to determine intestinal permeability. Severity was assessed on the basis of APACHE II scores and C-reactive protein measurements. Serum endotoxin and antiendotoxin antibodies were measured on admission. Eight-five patients with acute pancreatitis (mild in 56, severe in 29) and 25 healthy control subjects were studied. Urinary excretion of PEG 3350 (median) was significantly greater in patients who had severe attacks (0.61%) compared to those with mild disease (0.09%) and health control subjects (0.12%) (P <0. 0001), as was the permeability index (PEG 3350/400 excretion) (P <0. 00001). The permeability index was significantly greater in patients who subsequently developed multiple organ system failure and/or died compared with other severe cases (0.16 vs. 0.04) (P = 0.0005). The excretion of PEG 3350 correlated strongly with endotoxemia (r = 0.8; P = 0.002). Early increased intestinal permeability may play an important role in the pathophysiology of severe acute pancreatitis. Therapies that aim to restore intestinal barrier function may improve outcome.

    2013-11-01

    Medication overuse headache (MOH) is a daily, or almost daily, headache form that arises from overuse of one or more classes of migraine-abortive or analgesic medication. The main classes of drugs that cause MOH are opioids, butalbital-containing mixed analgesics, triptans, ergotamine tartrate derivatives, simple analgesics (except for plain aspirin), and perhaps non-steroidal anti-inflammatory drugs. MOH can be debilitating and results from biochemical and functional brain changes induced by certain medications taken too frequently. At this time, migraine and other primary headache disorders in which migraine or migraine-like elements occur seem exclusively vulnerable to the development of MOH. Other primary headache disorders are not currently believed to be vulnerable. The treatment of MOH consists of discontinuation of the offending drug(s), acute treatment of the withdrawal symptoms and escalating pain, establishing a preventive treatment when necessary, and the implementation of educational and behavioral programs to prevent recidivism. In most patients, MOH can be treated in the outpatient setting but, for the most difficult cases, including those with opioid or butalbital overuse, or in patients with serious medical or behavioral disturbances, effective treatment requires a multidisciplinary, comprehensive headache program, either day-hospital with infusion or an inpatient hospital setting.

    Primary headache disorders are frequently encountered in the pediatric population. The therapeutic approach consists of a multimodal program, including lifestyle modification, psychotherapeutic intervention, pharmacotherapy, and complementary measures. This systematic review focuses on the pharmacotherapy of pediatric migraine and tension-type headache (TTH). In addition to the general treatment principles, the results of 33 clinical reports published on the topic since 2008 are outlined in detail. Furthermore, a tabular summary of previously investigated agents not studied since 2008 is given, as is an overview of promising pharmacologic approaches so far only evaluated in adults. A variety of pharmacologic options is available, but high-quality evidence is limited to single agents. At this time, approval is restricted to four triptans and flupirtine for the symptomatic treatment of pediatric acute migraine and TTH, respectively. No agent has been approved for the prevention of pediatric primary headaches. This review does not grade the drugs hierarchically because the complex profiles of many agents differ only slightly or even overlap. However, a detailed expert opinion is provided. On the basis of the outlined facts, the team of physician, patient, and parents has to decide on the most appropriate regimen for the individual situation in the sense of personalized medicine.

    Stress induced by the events of daily life is considered a major factor in pathogenesis of primary tension-type headache. Little is known about the impact that could have a more stressful event, like a natural disaster, both in patients with chronic headache, both in people that do not had headache previously. The aim of the present study was to observe the prevalence of headache in the population following the devastating earthquake that affected the province of L'Aquila on April 6, 2009. The study population was conducted in four tent cities (Onna, Bazzano, Tempera-St. Biagio, Paganica). Sanitary access is recorded in the registers of medical triage, in the first 5 weeks, after the April 6, 2009. The prevalence of primary headache presentation was 5.53% (95% CI 4.2-7.1), secondary headache was 2.82% (95% CI 1.9-4.9). Pain intensity, assessed by Numerical Rating Scale score showed a mean value of 7±1.1 (range 4-10). The drugs most used were the NSAIDs (46%) and paracetamol (36%), for impossibility of finding causal drugs. This study shows how more stressful events not only have an important role in determining acute exacerbation of chronic headache, but probably also play a pathogenic role in the emergence of primary headache. Also underlines the lack of diagnostic guidelines or operating protocols to early identify and treat headache in the emergency settings. PMID:21331753

    Background: Headache is the most frequent symptom in cerebral venous thrombosis (CVT), and usually the first. However, it has rarely been reported as the only symptom of CVT. Objectives: To study the characteristics of patients in whom headache was the only presentation of CVT in the absence of intracranial hypertension, subarachnoid haemorrhage (SAH), meningitis, or other intracranial lesion. Methods: From a prospective study of 123 consecutive patients with CVT only those with isolated headache and normal brain computed tomography (CT) scan and cerebrospinal fluid (CSF) examination were included in the present study. All patients underwent an extensive systematic aetiological work-up and were given intravenous heparin followed by oral anticoagulants. A detailed description of the headache was obtained. Results: Headache was only sign of CVT in 17 patients. The lateral sinus was the most frequently involved sinus (n = 15). Onset of headache was progressive in 11, acute in 3, and thunderclap in 3 patients. Once established, the headache was continuous in 15, diffuse in four and unilateral in 13, usually ipsilateral to the occluded lateral sinus. No specific risk factor or cause was found. All had a favourable evolution. Conclusion: The pathogenesis of isolated headache in CVT in the absence of intracranial hypertension, SAH, meningitis or intracerebral lesion is unknown but may involve changes in the walls of the occluded sinus. Hence MRI/MRV should be used to look for signs of CVT in all patients with recent headache (progressive or thunderclap) even when the CT scan and CSF examination are normal. PMID:16024884

    Increased understanding of immune responses influencing clinical severity during pandemic influenza infection is important for improved treatment and vaccine development. In this study we recruited 46 adult patients during the 2009 influenza pandemic and characterized humoral and cellular immune responses. Those included were either acute hospitalized or convalescent patients with different disease severities (mild, moderate or severe). In general, protective antibody responses increased with enhanced disease severity. In the acute patients, we found higher levels of TNF-α single-producing CD4+T-cells in the severely ill as compared to patients with moderate disease. Stimulation of peripheral blood mononuclear cells (PBMC) from a subset of acute patients with peptide T-cell epitopes showed significantly lower frequencies of influenza specific CD8+ compared with CD4+ IFN-γ T-cells in acute patients. Both T-cell subsets were predominantly directed against the envelope antigens (HA and NA). However, in the convalescent patients we found high levels of both CD4+ and CD8+ T-cells directed against conserved core antigens (NP, PA, PB, and M). The results indicate that the antigen targets recognized by the T-cell subsets may vary according to the phase of infection. The apparent low levels of cross-reactive CD8+ T-cells recognizing internal antigens in acute hospitalized patients suggest an important role for this T-cell subset in protective immunity against influenza.

    Severe forms of acute respiratory distress syndrome in patients with haematological diseases expose clinicians to specific medical and ethical considerations. We prospectively followed 143 patients with haematological malignancies, and whose lungs were mechanically ventilated for more than 24 h, over a 5-y period. We sought to identify prognostic factors of long-term outcome, and in particular to evaluate the impact of the severity of acute respiratory distress syndrome in these patients. A secondary objective was to identify the early (first 48 h from ICU admission) predictive factors for acute respiratory distress syndrome severity. An evolutive haematological disease (HR 1.71; 95% CI 1.13-2.58), moderate to severe acute respiratory distress syndrome (HR 1.81; 95% CI 1.13-2.69) and need for renal replacement therapy (HR 2.24; 95% CI 1.52-3.31) were associated with long-term mortality. Resolution of neutropaenia during ICU stay (HR 0.63; 95% CI 0.42-0.94) and early microbiological documentation (HR 0.62; 95% CI 0.42-0.91) were associated with survival. The extent of pulmonary infiltration observed on the first chest X-ray and the diagnosis of invasive fungal infection were the most relevant early predictive factors of the severity of acute respiratory distress syndrome.

    Deletion of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) envelope (E) gene attenuates the virus. E gene encodes a small multifunctional protein that possesses ion channel (IC) activity, an important function in virus-host interaction. To test the contribution of E protein IC activity in virus pathogenesis, two recombinant mouse-adapted SARS-CoVs, each containing one single amino acid mutation that suppressed ion conductivity, were engineered. After serial infections, mutant viruses, in general, incorporated compensatory mutations within E gene that rendered active ion channels. Furthermore, IC activity conferred better fitness in competition assays, suggesting that ion conductivity represents an advantage for the virus. Interestingly, mice infected with viruses displaying E protein IC activity, either with the wild-type E protein sequence or with the revertants that restored ion transport, rapidly lost weight and died. In contrast, mice infected with mutants lacking IC activity, which did not incorporate mutations within E gene during the experiment, recovered from disease and most survived. Knocking down E protein IC activity did not significantly affect virus growth in infected mice but decreased edema accumulation, the major determinant of acute respiratory distress syndrome (ARDS) leading to death. Reduced edema correlated with lung epithelia integrity and proper localization of Na+/K+ ATPase, which participates in edema resolution. Levels of inflammasome-activated IL-1β were reduced in the lung airways of the animals infected with viruses lacking E protein IC activity, indicating that E protein IC function is required for inflammasome activation. Reduction of IL-1β was accompanied by diminished amounts of TNF and IL-6 in the absence of E protein ion conductivity. All these key cytokines promote the progression of lung damage and ARDS pathology. In conclusion, E protein IC activity represents a new determinant for SARS-CoV virulence. PMID:24788150

    The aims of this study were to assess spontaneous breathing patterns in patients with chronic obstructive pulmonary disease (COPD) recovering from acute exacerbation and to assess the relationship between different breathing patterns and clinical and functional parameters of respiratory impairment. Thirty-four COPD patients underwent assessment of lung function tests, arterial blood gases, haemodynamics, breathing pattern (respiratory frequency (fR), tidal volume (VT), inspiratory and expiratory time (tI and tE), duty cycle (tI/ttot), VT/tI) and mechanics (oesophageal pressure (Poes), work of breathing (WOB), pressure-time product and index, and dynamic intrinsic positive end-expiratory pressure (PEEPi,dyn)). According to the presence (group 1) or absence (group 2) of Poes swings during the expiratory phase (premature inspiration), 20 (59%) patients were included in group 1 and 14 (41%) in group 2. Premature inspirations were observed 4.5+/-6.4 times x min(-1) (range 1-31), i.e. 20+/-21% (3.7-100%) of total fR calculated from VT tracings. In group 1 the coefficient of variation in VT, tE, tI/ttot, PEEPi,dyn, Poes and WOB of the eight consecutive breaths immediately preceding the premature inspiration was greater than that of eight consecutive breaths in group 2. There were no significant differences in the assessed parameters between the two groups in the overall population, whereas patients with chronic hypoxaemia in group 1 showed a more severe impairment in clinical conditions, mechanics and lung function than hypoxaemic patients in group 2. In spontaneously breathing patients with chronic obstructive pulmonary disease recovering from an acute exacerbation, detectable activity of inspiratory muscles during expiration was found in more than half of the cases. This phenomenon was not associated with any significant differences in anthropometric, demographic, physiological or clinical characteristics. PMID:10065683

    Deletion of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) envelope (E) gene attenuates the virus. E gene encodes a small multifunctional protein that possesses ion channel (IC) activity, an important function in virus-host interaction. To test the contribution of E protein IC activity in virus pathogenesis, two recombinant mouse-adapted SARS-CoVs, each containing one single amino acid mutation that suppressed ion conductivity, were engineered. After serial infections, mutant viruses, in general, incorporated compensatory mutations within E gene that rendered active ion channels. Furthermore, IC activity conferred better fitness in competition assays, suggesting that ion conductivity represents an advantage for the virus. Interestingly, mice infected with viruses displaying E protein IC activity, either with the wild-type E protein sequence or with the revertants that restored ion transport, rapidly lost weight and died. In contrast, mice infected with mutants lacking IC activity, which did not incorporate mutations within E gene during the experiment, recovered from disease and most survived. Knocking down E protein IC activity did not significantly affect virus growth in infected mice but decreased edema accumulation, the major determinant of acute respiratory distress syndrome (ARDS) leading to death.

    National water-quality criteria for the protection of aquatic life are based on toxicity tests, often using organisms that are easy to culture in the laboratory. Species native to the Rocky Mountains are poorly represented in data sets used to derive national water-quality criteria. To provide additional data on the toxicity of zinc, several laboratory acute-toxicity tests were conducted with a diverse assortment of fish, benthic invertebrates, and an amphibian native to the Rocky Mountains. Tests with fish were conducted using three subspecies of cutthroat trout (Colorado River cutthroat trout Oncorhynchus clarkii pleuriticus, greenback cutthroat trout O. clarkii stomias, and Rio Grande cutthroat trout O. clarkii virginalis), mountain whitefish (Prosopium williamsoni), mottled sculpin (Cottus bairdi), longnose dace (Rhinichthys cataractae), and flathead chub (Platygobio gracilis). Aquatic invertebrate tests were conducted with mayflies (Baetis tricaudatus, Drunella doddsi, Cinygmula sp. and Ephemerella sp.), a stonefly (Chloroperlidae), and a caddis fly (Lepidostoma sp.). The amphibian test was conducted with tadpoles of the boreal toad (Bufo boreas). Median lethal concentrations (LC(50)s) ranged more than three orders of magnitude from 166 μg/L for Rio Grande cutthroat trout to >67,000 μg/L for several benthic invertebrates. Of the organisms tested, vertebrates were the most sensitive, and benthic invertebrates were the most tolerant. PMID:21811884

    Severe acute malnutrition (SAM) is associated with inadequate diet, low levels of plasma antioxidants and gut microbiota alterations. The link between gut redox and microbial alterations, however, remains unexplored. By sequencing the gut microbiomes of 79 children of varying nutritional status from three centers in Senegal and Niger, we found a dramatic depletion of obligate anaerobes in malnutrition. This was confirmed in an individual patient data meta-analysis including 107 cases and 77 controls from 5 different African and Asian countries. Specifically, several species of the Bacteroidaceae, Eubacteriaceae, Lachnospiraceae and Ruminococceae families were consistently depleted while Enterococcus faecalis, Escherichia coli and Staphylococcus aureus were consistently enriched. Further analyses on our samples revealed increased fecal redox potential, decreased total bacterial number and dramatic Methanobrevibacter smithii depletion. Indeed, M. smithii was detected in more than half of the controls but in none of the cases. No causality was demonstrated but, based on our results, we propose a unifying theory linking microbiota specificity, lacking anaerobes and archaea, to low antioxidant nutrients, and lower food conversion.

    The recent identification of a novel clinical entity, the severe acute respiratory syndrome (SARS), the rapid subsequent spread and case fatality rates of 14-15% have prompted a massive international collaborative investigation facilitated by a network of laboratories established by the World Health Organization (WHO). As SARS has the potential of becoming the first pandemic of the new millennium, a global warning by the WHO was issued on 12 March 2003. The disease, which is believed to have its origin in the Chinese Guangdong province, spread from Hong Kong via international airports to its current worldwide distribution. The concerted efforts of a globally united scientific community have led to the independent isolation and identification of a novel coronavirus from SARS patients by several groups. The extraordinarily rapid isolation of a causative agent of this newly emerged infectious disease constitutes an unprecedented scientific achievement. The main scope of the article is to provide the clinician with an overview of the natural history, epidemiology and clinical characteristics of SARS. On the basis of the recently published viral genome and structural features common to the members of the coronavirus family, a model for host cell-virus interaction and possible targets for antiviral drugs are presented. The epidemiological consequences of introducing a novel pathogen in a previously unexposed population and the origin and evolution of a new and more pathogenic strain of coronavirus are discussed.

    Vincristine, a critical component of combination chemotherapy treatment for pediatric acute lymphoblastic leukemia (ALL), can lead to vincristine-induced peripheral neuropathy (VIPN). Longitudinal VIPN assessments were obtained over 12 months from newly diagnosed children with ALL (N = 128) aged 1–18 years who received vincristine at one of four academic children’s hospitals. VIPN assessments were obtained using the Total Neuropathy Score-Pediatric Vincristine (TNS©-PV), National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE©), Balis© grading scale, and Pediatric Neuropathic Pain Scale©–Five (PNPS©-5). Of children who provided a full TNS©-PV score, 85/109 (78%) developed VIPN (TNS©-PV ≥4). Mean TNS©-PV, grading scale, and pain scores were low. CTCAE©-derived grades 3 and 4 sensory and motor VIPN occurred in 1.6%/0%, and 1.9%/0% of subjects, respectively. VIPN did not resolve in months 8–12 despite decreasing dose density. VIPN was worse in older children. Partition cluster analysis revealed 2–3 patient clusters; one cluster (n = 14) experienced severe VIPN. In this population, VIPN occurs more commonly than previous research suggests, persists throughout the first year of treatment, and can be severe. PMID:25977177

    We decided to assess the prognostic value of NLRP3 inflammasome level in acute coronary syndrome (ACS) patients and whether it was related to coronary atherosclerotic severity. Study population included one-hundred and twenty-three (123) subjects. Peripheral blood monocyte NLRP3 protein level was correlated with clinical presentation, angiographic characteristics and its scoring systems as well as GRACE and TIMI risk scores. Follow-up for major adverse cardiac events (MACE) was carried out at 180 days. Peripheral blood monocyte NLRP3 was found to be elevated in ACS patients (P < 0.05) and showed positive correlation with GRACE score (r = 0.619), TIMI score (r = 0.580), SYNTAX score (r = 0.550), Clinical SYNTAX score (r = 0.564) and Gensini score (r = 0.516). NLRP3 was also increased with increasing number of vessels, the number of lesions present and the presence bifurcation lesions (P < 0.05). Multivariate Cox regression analysis showed NLRP3 to be an independent predictor of MACE (P = 0.043). Kaplan-Meier analysis and receiver operating characteristic curves for NLRP3 showed good predictive value for MACE. There is a positive correlation of NLRP3 level with severity of coronary atherosclerosis. NLRP3 level is a promising prognostic utility and is efficient in event prediction for MACE. PMID:26290166

    Substance P (SP), a member of tachykinin family, is involved in the inflammation of the central nervous system and in the appearance of cerebral edema. Higher serum levels of SP have been found in 18 patients with cerebral ischemia compared with healthy controls. The aim of our multi-center study was to analyze the possible association between serum levels of SP and mortality in ischemic stroke patients. We included patients with malignant middle cerebral artery infarction (MMCAI) and a Glasgow Coma Scale (GCS) lower than 9. Non-surviving patients at 30 days (n = 31) had higher serum concentrations of SP levels at diagnosis of severe MMCAI than survivors (n = 30) (p < 0.001). We found in multiple regression an association between serum concentrations of SP higher than 362 pg/mL and mortality at 30 days (Odds Ratio = 5.33; 95% confidence interval = 1.541-18.470; p = 0.008) after controlling for age and GCS. Thus, the major novel finding of our study was the association between serum levels of SP and mortality in patients suffering from severe acute ischemic stroke. PMID:27338372

    Yokkaichi asthma was one of the most common environmental pollution diseases in Japan in the 1960s and 1970s. The problem of air pollution in Yokkaichi was solved in the 1970s. However, mortality and life expectancy were still affected by the late effects of air pollution in patients with Yokkaichi asthma even in the 2000s. In this case report, we described the experience of successful treatment of a patient with severe asthmatic status due to Yokkaichi asthma. A 40s-year-old man, who was officially certified as a patient with Yokkaichi asthma from his infancy, was admitted to hospital due to acute exacerbation of asthma. Mechanical ventilation, intravenous administration of aminophylline and dexamethasone, enteral administration of montelukast, and a transdermal patch of tulobuterol were started. However, because of the lack of improvement in clinical status, inhalation of procaterol using vibrating mesh nebulizer systems was started. Inhalation of procaterol was used three times a day. After using the vibrating mesh nebulizer, respiratory system compliance and hypercapnia rapidly improved. Bilateral expiratory wheezing was diminished. Weaning from mechanical ventilation was initiated, and on the eighth day of mechanical ventilation, the patient was extubated. Although intractable respiratory failure with decreased respiratory system compliance resulting from the late effects of air pollution and a long-time asthmatic inflammatory condition was observed, the use of a vibrating mesh nebulizer for the inhaled administration of procaterol was useful to relieve severe bronchospasm due to Yokkaichi asthma.

    A 55-year-old Japanese man with a 3-year history of type 2 diabetes mellitus was admitted to our hospital for upper abdominal pain. Control of diabetes mellitus was good with voglibose and metformin, with sitagliptin added to this regimen 8 months prior. His pancreatic enzyme levels were elevated, and abdominal computed tomography (CT) showed diffuse pancreatic swelling with fluid accumulation and ascites of CT grade 3. The patient was diagnosed with severe acute pancreatitis. There were no obvious causes for pancreatitis except the recently administered sitagliptin. Since incretin-related drugs entered the market, the number of incretin-related drugs prescriptions rapidly increased and so did the incidence of pancreatitis. There are several reports suggesting the correlation between incretin-related drugs and pancreatitis, such as a report based on data obtained from the United States Food and Drug Administration (FDA) which revealed a significant correlation between the administration of exenatide or sitagliptin and pancreatitis. However, there also is a report that denied the evidence for such in a large cohort study. The relation between incretin based drugs and pancreatitis is still controversial. PMID:23467428

    Impairments in neural function are common when oxygen supply to the brain is reduced. This study examined neurocognitive processes that are vulnerable to oxygen deprivation. We induced moderate-to-severe hypoxia in healthy adults, thereby inducing impairments caused by low brain oxygen availability. 22 healthy adults participated in this matched-pairs study with a single-blind, randomised design. Baseline neurocognitive function was examined during a familiarisation trial and participants were assigned to hypoxia (10% O2) or sham (21% O2) groups. Neurocognitive performance was assessed via computerised test battery after 50 min of breathing a gas mixture that reduced arterial oxygen saturation by 20% (p<0.01). Hypoxia severely reduced performance across all neurocognitive domain scores; with significant drops in neurocognitive index (-20%), composite memory (-30%), verbal memory (-34%), visual memory (-23%), processing speed (-36%), executive function (-20%), psychomotor speed (-24%), reaction time (-10%), complex attention (-19%) and cognitive flexibility (-18%; all p<0.05). Practice effects were blocked by hypoxia but occurred in sham for information processing speed (+30%), executive function (+14%), psychomotor speed (+18%), reaction time (+5%), cognitive flexibility (+14%), and overall cognitive functioning (+9%; all p<0.05). Neuropsychological performance decrements caused by acute experimental hypoxia are comparable to cognitive domains impaired with high altitude exposure and mild traumatic brain injury. PMID:25660759

    Cluster headache is a rare disorder that is more common in adult male patients. It has a unique phenotype of unilateral, severe, to very severe headaches lasting 15 to 180 min with ipsilateral autonomic symptoms. Time to correct diagnosis can be protracted. A number of treatment options exist for the standard cluster headache patient, but special considerations must be made for female patients of reproductive age and pediatric patients. The objective of this article is to explore the current literature pertaining to special considerations in cluster headache management, including treatment of pregnant or breastfeeding patients and pediatric patients.

    Hyperprolactinemia is a condition characterised by an increase of prolactin blood levels (more than 100-200 ng/ml). It is the most common endocrine disorder of the hypothalamic-pituitary axis. The clinical characteristics of the headache-hyperprolactinemia-hypophyseal-adenoma association are discussed, the various diagnostic and treatment possibilities are explored and the etiology of the headache is considered in the light of several pathogenetic possibilities. We present two cases. (1) A 35-year-old woman suffering from chronic tension-type headache interspersed with occasional episodes of migraine without aura (as defined by the International Headache Society criteria). She had also suffered menstrual cycle alterations since the age of 16. At the age of 30 she developed amenorrhea with hyperprolactinemia. Computed tomography (CT) and magnetic resonance imaging (MRI) scans revealed a median-left intrasellar mass. Treatment with cabergoline resulted in complete resolution of both types of headache and the menstrual cycle and prolactin levels returned to normal. The therapy also reduced the volume of the tumour. (2) The second case relates to a 47-year-old man who had been suffering from tension-type headaches for almost 3 months. The patient had never previously suffered from headaches. CT and MRI scans showed a large sellar and suprasellar lesion with raised serum prolactin levels. Treatment with cabergoline had significantly reduced the prolactin levels and had also improved the patient's headaches. High-resolution CT, with and without contrast, or MRI is necessary to visualise microprolactinomas (and other sellar lesions) and confirm the diagnosis. PMID:22639180

    Background: Migraine headaches are the most common acute and recurrent headaches. Current treatment of a migraine headache consists of multiple medications for control and prevention of recurrent attacks. Global emergence of alternative medicine led us to examine the efficacy of cupping therapy plus serkangabin syrup in the treatment of migraine headaches. Materials and Methods: This study was a randomized, controlled, open-label, comparative efficacy trial. We randomly assigned patients with migraine into cupping therapy plus serkangabin group (30 patients) and conventional treatment group (30 patients). An investigator assessed the severity of headache, frequency of attacks in a week and duration of attacks per hour in 5 visits (at the end of 2 weeks, 1, 3 and 6 months). Generalized estimating equations approach was used to analyze repeated measures data to compare outcomes in both groups. Results: Average age for cupping therapy group and conventional treatment group were 31.7 (±7.6) and 32.6 (±12.7) years, respectively (P = 0.45). After treatment for 2 weeks; and 1, 3 and 6 months, severity of headache (P = 0.80), frequency of migraine attacks (P = 0.63) and duration of attacks per hours (P = 0.48) were similar in conventional and cupping groups but these symptoms were decreased in each group during the study (P < 0.001). Conclusion: There was no significant difference between cupping plus serkangabin therapy and conventional treatment in the treatment and prophylaxis of migraine. The alternative therapy may be used in cases of drug intolerance, no medication response, and in primary care. PMID:25709653

    Background Several nonsteroidal anti-inflammatory drugs (NSAIDs) have been shown to be effective in the treatment of migraine. However, few commercially available NSAIDs can be administered IV. Lysine clonixinate (LC), an NSAID derived from nicotinic acid, has been proved effective in various algesic syndromes (eg, renal colic, muscular pain, nerve compression, odontalgia). The oral formulation of LC has been shown to be effective in the treatment of migraine of moderate severity. Objective The aim of this study was to assess the efficacy and tolerability of the IV formulation of LC in the treatment of severe migraine. Methods This double-blind, randomized, placebo-controlled, prospective study enrolled patients with severe migraine (without aura) as defined by the criteria of the International Headache Society. When patients presented to a neurology hospital with an outpatient headache unit (Instituto de Neurologia Deolindo Couto, Rio de Janeiro, Brazil) with a severe migraine attack that had lasted <4 hours, they were randomized to 1 of 2 groups (IV placebo [25 mL of 0.9% saline] or IV LC [21 mL of 0.9% saline plus 4 mL of LC 200 mg]). Headache intensity and adverse effects (AEs) were assessed before (0 minute) and 30, 60, and 90 minutes after study drug administration. Rescue medication was available 2 hours after study drug administration, and its use was compared between groups. Results Thirty-two patients (23 women, 9 men; mean [SD] age, 32 [2] years; range, 18–58 years) entered the study. Twenty-nine patients (21 women, 8 men; mean [SD] age, 32 [2] years; range, 18–56 years) completed the study. Three patients (all in the placebo group) did not complete the study (1 patient was unable to rate the pain severity after drug administration and 2 patients refused IV drug administration). Among study completers, 17 patients received LC and 12 placebo. At 30 minutes, 1 patient (8.3%) in the placebo group and 5 patients (29.4%) in the LC group were pain free

  4. Headache and sleep disorders: review and clinical implications for headache management.

    Review of epidemiological and clinical studies suggests that sleep disorders are disproportionately observed in specific headache diagnoses (eg, migraine, tension-type, cluster) and other nonspecific headache patterns (ie, chronic daily headache, "awakening" or morning headache). Interestingly, the sleep disorders associated with headache are of varied types, including obstructive sleep apnea (OSA), periodic limb movement disorder, circadian rhythm disorder, insomnia, and hypersomnia. Headache, particularly morning headache and chronic headache, may be consequent to, or aggravated by, a sleep disorder, and management of the sleep disorder may improve or resolve the headache. Sleep-disordered breathing is the best example of this relationship. Insomnia is the sleep disorder most often cited by clinical headache populations. Depression and anxiety are comorbid with both headache and sleep disorders (especially insomnia) and consideration of the full headache-sleep-affective symptom constellation may yield opportunities to maximize treatment. This paper reviews the comorbidity of headache and sleep disorders (including coexisting psychiatric symptoms where available). Clinical implications for headache evaluation are presented. Sleep screening strategies conducive to headache practice are described. Consideration of the spectrum of sleep-disordered breathing is encouraged in the headache population, including awareness of potential upper airway resistance syndrome in headache patients lacking traditional risk factors for OSA. Pharmacologic and behavioral sleep regulation strategies are offered that are also compatible with treatment of primary headache. PMID:17040332

    Background Multiple viruses are often detected in children with respiratory infection but the significance of co-infection in pathogenesis, severity and outcome is unclear. Objectives To correlate the presence of viral co-infection with clinical phenotype in children admitted with acute respiratory infections (ARI). Methods We collected detailed clinical information on severity for children admitted with ARI as part of a Spanish prospective multicenter study (GENDRES network) between 2011–2013. A nested polymerase chain reaction (PCR) approach was used to detect respiratory viruses in respiratory secretions. Findings were compared to an independent cohort collected in the UK. Results 204 children were recruited in the main cohort and 97 in the replication cohort. The number of detected viruses did not correlate with any markers of severity. However, bacterial superinfection was associated with increased severity (OR: 4.356; P-value = 0.005), PICU admission (OR: 3.342; P-value = 0.006), higher clinical score (1.988; P-value = 0.002) respiratory support requirement (OR: 7.484; P-value < 0.001) and longer hospital length of stay (OR: 1.468; P-value < 0.001). In addition, pneumococcal vaccination was found to be a protective factor in terms of degree of respiratory distress (OR: 2.917; P-value = 0.035), PICU admission (OR: 0.301; P-value = 0.011), lower clinical score (-1.499; P-value = 0.021) respiratory support requirement (OR: 0.324; P-value = 0.016) and oxygen necessity (OR: 0.328; P-value = 0.001). All these findings were replicated in the UK cohort. Conclusion The presence of more than one virus in hospitalized children with ARI is very frequent but it does not seem to have a major clinical impact in terms of severity. However bacterial superinfection increases the severity of the disease course. On the contrary, pneumococcal vaccination plays a protective role. PMID:27096199

    This report summarizes the secondary headache attributed to dental disease. Among a lot of dental diseases, the temporomandibular disorder(TMD) is the most important for understanding the mechanism of this type of headache. Our recent study showed that TMD patients had the following symptoms: dysdiadochokinesia, abnormal induced-rigidity in forearms, abnormal circadian rhythm, tension-type headache and mental torment. All these abnormal symptoms were relieved by the improvement of the patient's sleep-quality. The brain monoaminergic systems are known to be related to muscle tonus, sleep problems and mental symptoms. Our studies of a serotonin transporter(5-HTT) gene promoter polymorphism showed that the L and XL alleles were more frequent and S allele was less frequent in the TMD compared to the controls. We speculate the brain monoaminergic systems play the important pathophysiological roles on the TMD. PMID:16218390

    Background: Pancreatic infections and sepsis are major complications in severe acute pancreatitis (AP) with significant impact on management and outcome. We investigated the value of Procalcitonin (PCT) for identifying patients at risk to develop pancreatic infections in severe AP. Methods: A total of 104 patients with predicted severe AP were enrolled in five European academic surgical centers within 96 hours of symptom onset. PCT was measured prospectively by a semi-automated immunoassay in each center, C-reactive protein (CRP) was routinely assessed. Both parameters were monitored over a maximum of 21 consecutive days and in weekly intervals thereafter. Results: In contrast to CRP, PCT concentrations were significantly elevated in patients with pancreatic infections and associated multiorgan dysfunction syndrome (MODS) who all required surgery (n = 10) and in nonsurvivors (n = 8) early after onset of symptoms. PCT levels revealed only a moderate increase in patients with pancreatic infections in the absence of MODS (n = 7), all of whom were managed nonoperatively without mortality. A PCT value of ≥3.5 ng/mL on 2 consecutive days was superior to CRP ≥430 mg/L for the assessment of infected necrosis with MODS or nonsurvival as determined by ROC analysis with a sensitivity and specificity of 93% and 88% for PCT and 40% and 100% for CRP, respectively (P < 0.01). The single or combined prediction of the two major complications was already possible on the third and fourth day after onset of symptoms with a sensitivity and specificity of 79% and 93% for PCT ≥3.8 ng/mL compared with 36% and 97% for CRP ≥430 mg/L, respectively (P = 0.002). Conclusion: Monitoring of PCT allows early and reliable assessment of clinically relevant pancreatic infections and overall prognosis in AP. This single test parameter significantly contributes to an improved stratification of patients at risk to develop major complications. PMID:17457167

    Rehabilitation can improve cognitive deficits observed in patients with traumatic brain injury (TBI). However, despite rehabilitation, the ability of making a choice often remains impaired. Risk taking is a daily activity involving numerous cognitive processes subserved by a complex neural network. In this work we investigated risk taking using the Balloon Analogue Risk Task (BART) in patients with acute TBI and healthy controls. We hypothesized that individuals with TBI will take less risk at the BART as compared to healthy individuals. We also predicted that within the TBI group factors such as the number of days since the injury, severity of the injury, and sites of the lesion will play a role in risk taking as assessed with the BART. Main findings revealed that participants with TBI displayed abnormally cautious risk taking at the BART as compared to healthy subjects. Moreover, healthy individuals showed increased risk taking throughout the task which is in line with previous work. However, individuals with TBI did not show this increased risk taking during the task. We also investigated the influence of three patients' characteristics on their performance at the BART: Number of days post injury, Severity of the head injury, and Status of the frontal lobe. Results indicate that performance at the BART was influenced by the number of days post injury and the status of the frontal lobe, but not by the severity of the head injury. Reported findings are encouraging for risk taking seems to naturally improve with time postinjury. They support the need of conducting longitudinal prospective studies to ultimately identify impaired and intact cognitive skills that should be trained postinjury. PMID:24386232

    Hypoxia whether present during physiologic states (e.g., embryogenesis) or during pathologic states (e.g., obstructive sleep apnea and sickle cell anemia), challenges the vertebrate or invertebrate organism. Clearly, hypoxia can lead to sublethal cell injury or death and consequently organ or systemic injury and failure, depending on severity. We discovered that the adult Drosophila melanogaster is tolerant to a low O(2) environment, withstanding approximately 3-4 hours of total O(2) deprivation or anoxia without showing any evidence of cell injury. This opened major avenues for us since the Drosophila has been used so effectively in so many relevant research areas. We investigated the changes in gene expression in D. melanogaster after severe (1% O(2)) intermittent or constant hypoxia treatment for 2.5 hours. Our microarray analysis has identified multiple gene families that are up- or downregulated in response to acute constant (CH) and intermittent hypoxia (IH). We observed that even for short-term the gene expression response to IH and CH varied not only in the number of genes but also type of gene families. Furthermore, by utilizing powerful Drosophila genetic tools we studied the role of single genes (up- or downregulated in arrays) in survival under either paradigm in adult flies. We observed significant increased adult survival (as compared to controls) of P-element lines for Hsp70 and Hsp23 genes during CH and Mdr49 and l (2)08717 genes during IH. This suggests that the increased transcript levels as observed in array data after either paradigm play an important role under severe hypoxia. Indeed, we found for example that over-expressing Hsp70 in vivo in specific fly organs (such as heart) significantly increased adult survival during CH as compared to controls. These data provide further clues about the mechanisms by which intermittent and constant hypoxia lead to cell injury and morbidity or adaptation and survival. PMID:19845605

    Abstract Torres-Peralta, Rafael, José Losa-Reyna, Miriam González-Izal, Ismael Perez-Suarez, Jaime Calle-Herrero, Mikel Izquierdo, and José A.L. Calbet. Muscle activation during exercise in severe acute hypoxia: Role of absolute and relative intensity. High Alt Med Biol 15:472–482, 2014.—The aim of this study was to determine the influence of severe acute hypoxia on muscle activation during whole body dynamic exercise. Eleven young men performed four incremental cycle ergometer tests to exhaustion breathing normoxic (FIo2=0.21, two tests) or hypoxic gas (FIo2=0.108, two tests). Surface electromyography (EMG) activities of rectus femoris (RF), vastus medialis (VL), vastus lateralis (VL), and biceps femoris (BF) were recorded. The two normoxic and the two hypoxic tests were averaged to reduce EMG variability. Peak Vo2 was 34% lower in hypoxia than in normoxia (p<0.05). The EMG root mean square (RMS) increased with exercise intensity in all muscles (p<0.05), with greater effect in hypoxia than in normoxia in the RF and VM (p<0.05), and a similar trend in VL (p=0.10). At the same relative intensity, the RMS was greater in normoxia than in hypoxia in RF, VL, and BF (p<0.05), with a similar trend in VM (p=0.08). Median frequency increased with exercise intensity (p<0.05), and was higher in hypoxia than in normoxia in VL (p<0.05). Muscle contraction burst duration increased with exercise intensity in VM and VL (p<0.05), without clear effects of FIo2. No significant FIo2 effects on frequency domain indices were observed when compared at the same relative intensity. In conclusion, muscle activation during whole body exercise increases almost linearly with exercise intensity, following a muscle-specific pattern, which is adjusted depending on the FIo2 and the relative intensity of exercise. Both VL and VM are increasingly involved in power output generation with the increase of intensity and the reduction in FIo2. PMID:25225839

    Ventilation-perfusion (VA/Q) relationships and gas exchange were studied by the multiple inert gas technique in 19 patients admitted to hospital with acute severe asthma (FEV1 41% predicted) before and during the administration of intravenous salbutamol, inhaled salbutamol, or 100% oxygen. Eight patients received a continuous intravenous infusion of salbutamol (4 micrograms/min, total dose 360 micrograms) and were studied before treatment, after 60 and 90 minutes of treatment, and one hour after treatment had been discontinued. Six patients had measurements before and 15 minutes after inhaling 300 micrograms salbutamol from a metered dose inhaler on two occasions (total dose 600 micrograms) and one hour after the last dose. Measurements were also made in five patients before and while they breathed 100% oxygen for 20 minutes. At baseline (fractional inspired oxygen (FiO2) 21%) all patients showed a broad unimodal (n = 10) or bimodal (n = 9) distribution of blood flow with respect to VA/Q. A mean of 10.5% of the blood flow was associated with low VA/Q units without any appreciable shunt. One of the best descriptors of VA/Q inequality, the second moment of the perfusion distribution on a log scale (log SD Q), was moderately high with a mean of 1.18 (SEM 0.08) (normal less than 0.6). Measures of VA/Q inequality correlated poorly with spirometric findings. After salbutamol the increase in airflow rates was similar regardless of the route of administration. Intravenous salbutamol, however, caused a significant increase in heart rate, cardiac output, and oxygen consumption (VO2); in addition, both perfusion to low VA/Q areas and log SD Q increased significantly. Inhaled salbutamol caused only minor changes in heart rate, cardiac output, VO2, and VA/Q inequality. Arterial oxygen tension (PaO2) remained unchanged during salbutamol administration, irrespective of the route of administration. During 100% oxygen breathing there was a significant increase in log SD Q (from 1

    There are multiple risk factors for chronic daily headache (CDH), but they are usually assessed in an isolated form without an adequate control for confounders. CDH is considered a variant of episodic headache, but studies have not gathered enough evidence to evaluate simultaneously CDH and episodic in the same population. We set out to establish simultaneously the factors associated with chronic daily or episodic headache in a population setting, using a cross-sectional survey in a random sample of 1505 adult urban inhabitants (Bucaramanga, Colombia). The survey asked questions about headache, family and personal history of disease, and consumption or abuse of caffeine, alcohol, hypnotics and analgesics. The association among independent variables and CDH or episodic headache was made with multinomial logistic regression. Female gender, arterial hypertension or cranial trauma history, and a high score in the depression scale are associated with episodic headache and CDH. Parents with CDH, the complaint of multiple arousals during sleep and use of hypnotics are associated with CDH, but not with episodic headache. Age <36 years, alcoholism and snoring are factors associated only with episodic headache. Chronic daily headache and episodic headache have several common risk factors, but there are other factors not shared by both conditions. PMID:18254892

    This study examined how illness schemata-ways people organize information about illness-change over the course of cognitive-behavioral treatment of chronic headache and the extent to which such changes predict reduction of headache. 73 subjects with chronic migraine, mixed migraine and tension, or tension headache were classified on the basis of outcome from imagery-based treatment as Treatment-responders (n = 24). Treatment nonresponders (n = 27), and Monitoring Controls (n = 22). Self-reported illness schemata related to the seriousness and changeability of headache were assessed at pretreatment and 8-wk. follow-up. While groups did not differ on pretreatment measures of illness schemata, at follow-up the Treatment responder group reported higher Changeability scores than Treatment-nonresponders and Control subjects and lower Seriousness scores than Control subjects. Headache reduction at follow-up was related to follow-up Changeability scores, in-session changes in systolic blood pressure and reported posttreatment expectations of headache activity, but not pretreatment measures of illness schemata. Findings indicate that improvements in headache activity are not influenced by the severity of headaches and may change prior to cognitive-behavioral treatment. Rather, among individuals who show decreases in headache activity, changes in beliefs about illness and headache reduction may have reciprocal relations both of which result from cognitive behavioral treatment.

    Object The aim of the study was to evaluate the early changes in pituitary hormone levels after severe traumatic brain injury (sTBI) and compare hormone levels to basic neuro-intensive care data, a systematic scoring of the CT-findings and to evaluate whether hormone changes are related to outcome. Methods Prospective study, including consecutive patients, 15–70 years, with sTBI, Glasgow Coma Scale (GCS) score ≤ 8, initial cerebral perfusion pressure > 10 mm Hg, and arrival to our level one trauma university hospital within 24 hours after head trauma (n = 48). Serum samples were collected in the morning (08–10 am) day 1 and day 4 after sTBI for analysis of cortisol, growth hormone (GH), prolactin, insulin-like growth factor 1 (IGF-1), thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), follicular stimulating hormone (FSH), luteinizing hormone (LH), testosterone and sex hormone-binding globulin (SHBG) (men). Serum for cortisol and GH was also obtained in the evening (17–19 pm) at day 1 and day 4. The first CT of the brain was classified according to Marshall. Independent staff evaluated outcome at 3 months using GOS-E. Results Profound changes were found for most pituitary-dependent hormones in the acute phase after sTBI, i.e. low levels of thyroid hormones, strong suppression of the pituitary-gonadal axis and increased levels of prolactin. The main findings of this study were: 1) A large proportion (54% day 1 and 70% day 4) of the patients showed morning s-cortisol levels below the proposed cut-off levels for critical illness related corticosteroid insufficiency (CIRCI), i.e. <276 nmol/L (=10 ug/dL), 2) Low s-cortisol was not associated with higher mortality or worse outcome at 3 months, 3) There was a significant association between early (day 1) and strong suppression of the pituitary-gonadal axis and improved survival and favorable functional outcome 3 months after sTBI, 4) Significantly lower levels of fT3

    Coronaviruses are a family of enveloped, single-stranded, positive-strand RNA viruses classified within the Nidovirales order. This coronavirus family consists of pathogens of many animal species and of humans, including the recently isolated severe acute respiratory syndrome coronavirus (SARS-CoV). This review is divided into two main parts; the first concerns the animal coronaviruses and their pathogenesis, with an emphasis on the functions of individual viral genes, and the second discusses the newly described human emerging pathogen, SARS-CoV. The coronavirus part covers (i) a description of a group of coronaviruses and the diseases they cause, including the prototype coronavirus, murine hepatitis virus, which is one of the recognized animal models for multiple sclerosis, as well as viruses of veterinary importance that infect the pig, chicken, and cat and a summary of the human viruses; (ii) a short summary of the replication cycle of coronaviruses in cell culture; (iii) the development and application of reverse genetics systems; and (iv) the roles of individual coronavirus proteins in replication and pathogenesis. The SARS-CoV part covers the pathogenesis of SARS, the developing animal models for infection, and the progress in vaccine development and antiviral therapies. The data gathered on the animal coronaviruses continue to be helpful in understanding SARS-CoV. PMID:16339739

    The severe acute respiratory syndrome coronavirus enters cells through the activities of a spike protein (S) which has receptor-binding (S1) and membrane fusion (S2) regions. We have characterized four sequential states of a purified recombinant S ectodomain (S-e) comprising S1 and the ectodomain of S2. They are S-e monomers, uncleaved S-e trimers, cleaved S-e trimers, and dissociated S1 monomers and S2 trimer rosettes. Lowered pH induces an irreversible transition from flexible, L-shaped S-e monomers to clove-shaped trimers. Protease cleavage of the trimer occurs at the S1-S2 boundary; an ensuing S1 dissociation leads to a major rearrangement of the trimeric S2 and to formation of rosettes likely to represent clusters of elongated, postfusion trimers of S2 associated through their fusion peptides. The states and transitions of S suggest conformational changes that mediate viral entry into cells. PMID:16809285

    Background: Recent reports about the benefits of corticosteroid therapy in patients with severe acute pancreatitis (SAP) have shown conflicting results. We aimed to explore the effects of corticosteroid therapy in SAP patients on patient outcomes by performing a meta-analysis. Methods: Databases (Medline, EMBASE, Web of Science, PubMed, Cochrane Library, Chinese Biomedicine Database, and China Academic Journal Full-Text Database) were queried for all relevant, randomized, controlled trials investigating corticosteroid therapy in patients with SAP. Results: Six randomized, controlled trials including 430 SAP patients were identified. Corticosteroid therapy for SAP was associated with reductions in the length of hospital stay, the need for surgical intervention, and the mortality rate (weighted mean difference [WMD]: -9.47, 95% confidence interval [CI]: -16.91 to -2.04, P = 0.01; odds ratio [OR]: 0.35, 95% CI: 0.18-0.67, P = 0.002; OR: 0.45, 95% CI: 0.22-0.94, P = 0.03). There were no significant differences in the complication rates or Physiology and Chronic Health Evaluation II (APACHE II) scores in patients with or without corticosteroid therapy. Conclusion: Corticosteroid therapy may improve outcomes in patients with SAP. PMID:26339332

    It has been proved that severe acute respiratory syndrome (SARS) is caused by SARS-associated coronavirus, a novel coronavirus. SARS originated in Guangdong Province, the People's Republic of China at the end of 2002. At present, it has spread to more than 33 countries or regions all over the world and affected 8360 people and killed 764 by May 31, 2003. Identification of the SARS causative agent and development of a diagnostic test are important. Detecting disease in its early stage, understanding its pathways of transmission and implementing specific prevention measures for the disease are dependent upon swift progress. Due to the efforts of the WHO-led network of laboratories testing for SARS, tests for the novel coronavirus have been developed with unprecedented speed. The genome sequence reveals that this coronavirus is only moderately related to other known coronaviruses. WHO established the definitions of suspected and confirmed and probable cases. But the laboratory tests and definitions are limited. Until now, the primary measures included isolation, ribavirin and corticosteroid therapy, mechanical ventilation, etc. Other therapies such as convalescent plasma are being explored. It is necessary to find more effective therapy. There still are many problems to be solved in the course of conquering SARS. PMID:12800213

    Severe acute respiratory syndrome coronavirus (SARS-CoV) causes a lung disease with high mortality. In addition, osteonecrosis and bone abnormalities with reduced bone density have been observed in patients following recovery from SARS, which were partly but not entirely explained by the short-term use of steroids. Here, we demonstrate that human monocytes, potential precursors of osteoclasts, partly express angiotensin converting enzyme 2 (ACE2), a cellular receptor of SARS-CoV, and that expression of an accessory protein of SARS-CoV, 3a/X1, in murine macrophage cell line RAW264.7 cells, enhanced NF-kappaB activity and differentiation into osteoclast-like cells in the presence of receptor activator of NF-kappaB ligand (RANKL). Furthermore, human epithelial A549 cells expressed ACE2, and expression of 3a/X1 in these cells up-regulated TNF-alpha, which is known to accelerate osteoclastogenesis. 3a/X1 also enhanced RANKL expression in mouse stromal ST2 cells. These findings indicate that SARS-CoV 3a/X1 might promote osteoclastogenesis by direct and indirect mechanisms. PMID:19685004

    Hypercalcemia is a rare metabolic disorder in children and is potentially fatal. It has a wide differential diagnosis, including cancer. Here, we report the case of a previously healthy 3-year-old who was admitted to the emergency room with fatigue, hyporeactivity, fever and limping gait that had evolved over 5 days and that was progressively worsening. On examination the patient was unconscious (Glasgow coma score: 8). Laboratory tests indicated severe hypercalcemia (total calcium 21.39mg/dL, ionized calcium 2.93mmol/L) and microcytic anemia. Hyperhydration was initiated, and the child was transferred to the pediatric intensive care unit. Continuous venovenous hemodiafiltration with calcium-free solution was instituted, which brought progressive normalization of serum calcium and an improved state of consciousness. Zoledronate was administered, and metabolic and infectious causes and poisoning were excluded. The bone marrow smear revealed a diagnosis of acute lymphoblastic leukemia. Hypercalcemia associated with malignancy in children is rare and occurs as a form of cancer presentation or recurrence. Continuous venovenous hemodiafiltration should be considered in situations where there is imminent risk to life. PMID:26761480

    The outbreak of severe acute respiratory syndrome (SARS) is still threatening the world because of a possible resurgence. In the current situation that effective medical treatments such as antiviral drugs are not discovered yet, dynamical features of the epidemics should be clarified for establishing strategies for tracing, quarantine, isolation, and regulating social behavior of the public at appropriate costs. Here we propose a network model for SARS epidemics and discuss why superspreaders emerged and why SARS spread especially in hospitals, which were key factors of the recent outbreak. We suggest that superspreaders are biologically contagious patients, and they may amplify the spreads by going to potentially contagious places such as hospitals. To avoid mass transmission in hospitals, it may be a good measure to treat suspected cases without hospitalizing them. Finally, we indicate that SARS probably propagates in small-world networks associated with human contacts and that the biological nature of individuals and social group properties are factors more important than the heterogeneous rates of social contacts among individuals. This is in marked contrast with epidemics of sexually transmitted diseases or computer viruses to which scale-free network models often apply.

    Local or systemic inflammation can result in acute lung injury (ALI), and is associated with capillary leakage, reduced lung compliance, and hypoxemia. Curcumin, a plant-derived polyphenolic compound, exhibits potent anti-inflammatory properties, but its poor solubility and limited oral bioavailability reduce its therapeutic potential. A novel curcumin formulation (CDC) was developed by complexing the compound with hydroxypropyl-γ-cyclodextrin (CD). This results in greatly enhanced water solubility and stability that facilitate direct pulmonary delivery. In vitro studies demonstrated that CDC increased curcumin's association with and transport across Calu-3 human airway epithelial cell monolayers, compared with uncomplexed curcumin solubilized using DMSO or ethanol. Importantly, Calu-3 cell monolayer integrity was preserved after CDC exposure, whereas it was disrupted by equivalent uncomplexed curcumin solutions. We then tested whether direct delivery of CDC to the lung would reduce severity of ALI in a murine model. Fluorescence microscopic examination revealed an association of curcumin with cells throughout the lung. The administration of CDC after LPS attenuated multiple markers of inflammation and injury, including pulmonary edema and neutrophils in bronchoalveolar lavage fluid and lung tissue. CDC also reduced oxidant stress in the lungs and activation of the proinflammatory transcription factor NF-κB. These results demonstrate the efficacy of CDC in a murine model of lung inflammation and injury, and support the feasibility of developing a lung-targeted, curcumin-based therapy for the treatment of patients with ALI.

    Limited studies have investigated the prevalence of insomnia symptoms among individuals with different headache diagnoses and the association between insomnia and headache in subjects with comorbid anxiety and depression. A total of 310 community-dwelling Hong Kong Chinese women aged 40-60 years completed a self-administered questionnaire on headache, sleep difficulties, mood disturbances, and functional impairment. About 31% of the sample complained of recurrent headache unrelated to influenza and the common cold in the past 12 months. The percentages of women diagnosed to have migraine, tension-type headache (TTH), and headache unspecified were 8.4, 15.5 and 7.1%, respectively. The most frequent insomnia complaint was "problem waking up too early" (29.4%), followed by "difficulty staying asleep" (28.0%) and "difficulty falling asleep" (24.4%). Women with headaches were significantly more likely to report insomnia symptoms than those without headaches. There were no significant differences among women with migraine, TTH, and headache unspecified in the prevalence of insomnia symptoms. Logistic regression analysis showed that women with insomnia disorder as defined by an insomnia severity index total score >or=8 had 2.2-fold increased risk of reporting recurrent headache, 3.2-fold increased risk of migraine, and 2.3-fold increased risk of TTH, after adjusting for anxiety and depression. Individual insomnia symptoms were not independent predictors. The association between insomnia and headache was stronger in subjects with more frequent headaches. Our findings suggest that insomnia and the associated distress, but not insomnia symptoms alone, is an independent risk factor for recurrent headache in middle-aged women with mixed anxiety, depression and sleep disturbances.

    The Severe Acute Respiratory Syndrome (SARS) is the first severe and easily transmissible disease to emerge in the 21st century. It is caused by the infection with a coronavirus, a single strand RNA capsulated virus, recently found in a small mammalian, the masked palm civet. It is likely to represent the source of human infection. The first cases of SARS have been reported in the Chinese province of Guangdong and, since then, probable cases have been reported world wide. The clinical picture is characterized by nonspecific symptoms such as fever, cough or dyspnea in patients affected by air-space opacities (unifocal involvement in the 54.6% of cases) or distress respiratory syndrome and linked to a recent exposure to a SARS case or to a travel/residence in an affected area. The empirical therapy is based on broad-spectrum antibiotics, steroids and ribavirin, but susceptibility testing have failed to demonstrate direct anti-viral activity of ribavirin against SARS-related coronavirus in vitro. The exposure to respiratory droplets and the contact with biologic fluids (respiratory and gastrointestinal secretions) represent the most efficient transmission modality of the SARS-related coronavirus. Hand hygiene is the most simple and cost effective measure of infection control to prevent contagion, and the use of airborne, contact and droplet precaution is strictly recommended to all health care workers taking care of such patients. The spread of SARS, to less developed country with limited resource for public health programs, represent the emerging alarming threat in the new global scenario. PMID:12868234

    This study was designed to determine the effects and compare laparoscopic intervention and open surgery in treating severe acute pancreatitis (SAP) and its relative aftercare, to improve the overall treatment of SAP. Ninety patients with SAP were enrolled from the 2nd Affiliated Hospital of Harbin Medical University from 2008 to 2014 and divided into a laparoscopic intervention group (25 cases) and an open surgery group (65 cases). Patients were asked for clinical symptoms, general hospital information, laboratory inspection, imageological examination, local and systemic complications, treatment and outcome. SAP patients’ relevant clinical indicators were compared between the two groups before and after the operation. Results revealed that there was no statistical significance in lesion range and main scoring indexes for reflecting the severity of the disease. For both groups statistical significance was found in blood loss (285.3±79.8 mL vs 362±91.6 mL), intensive care unit (ICU) monitoring time (9.04±6.35 d vs 12.48±8.34 d) and service time of breathing machine (9.47±6.24 d vs 12.98±8.25 d), and the laparoscopic operation group was superior to the open surgery group (p < 0.05). Besides, the laparoscopic operation group was also superior to the open surgery group in demand for main analgesics one week after the operation, as well as for recovery rate and incidence of complications (p < 0.05). Thus, it can be concluded that patients undergoing laparoscopic intervention are less likely to develop pulmonary infection and more likely to be cured in comparison with patients who receive open surgery. In addition, laparoscopic intervention results in less damage, lighter pain and fewer complications compared with open surgery. PMID:27049091

    Background Severe acute malnutrition (SAM) among children remains a major health problem in many developing countries. SAM manifests in both an oedematous and a non-oedematous form, with oedematous malnutrition in its most severe form also known as kwashiorkor. The pathogenesis of both types of malnutrition in children remains largely unknown, but gut microbiota (GM) dysbiosis has recently been linked to oedematous malnutrition. In the present study we aimed to assess whether GM composition differed between Ugandan children suffering from either oedematous or non-oedematous malnutrition. Methodology/Principal Findings As part of an observational study among children hospitalized with SAM aged 6–24 months in Uganda, fecal samples were collected at admission. Total genomic DNA was extracted from fecal samples, and PCR amplification was performed followed by Denaturing Gradient Gel Electrophoresis (DGGE) and tag-encoded 16S rRNA gene-targeted high throughput amplicon sequencing. Alpha and beta diversity measures were determined along with ANOVA mean relative abundance and G-test of independence followed by comparisons between groups. Of the 87 SAM children included, 62% suffered from oedematous malnutrition, 66% were boys and the mean age was 16.1 months. GM composition was found to differ between the two groups of children as determined by DGGE (p = 0.0317) and by high-throughput sequencing, with non-oedematous children having lower GM alpha diversity (p = 0.036). However, beta diversity analysis did not reveal larger differences between the GM of children with oedematous and non-oedematous SAM (ANOSIM analysis, weighted UniFrac, R = -0.0085, p = 0.584; unweighted UniFrac, R = 0.0719, p = 0.011). Conclusions/Significance Our results indicate that non-oedematous SAM children have lower GM diversity compared to oedematous SAM children, however no clear compositional differences were identified.

    Molecular hydrogen, which reacts with the hydroxyl radical, has been considered as a novel antioxidant. Here, we evaluated the protective effects of hydrogen-rich saline on the L-arginine (L-Arg)-induced acute pancreatitis (AP). AP was induced in Sprague-Dawley rats by giving two intraperitoneal injections of L-Arg, each at concentrations of 250 mg/100 g body weight, with an interval of 1 h. Hydrogen-rich saline (>0.6 mM, 6 ml/kg) or saline (6 ml/kg) was administered, respectively, via tail vein 15 min after each L-Arg administration. Severity of AP was assessed by analysis of serum amylase activity, pancreatic water content and histology. Samples of pancreas were taken for measuring malondialdehyde and myeloperoxidase. Apoptosis in pancreatic acinar cell was determined with terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling technique (TUNEL). Expression of proliferating cell nuclear antigen (PCNA) and nuclear factor kappa B (NF-{kappa}B) were detected with immunohistochemistry. Hydrogen-rich saline treatment significantly attenuated the severity of L-Arg-induced AP by ameliorating the increased serum amylase activity, inhibiting neutrophil infiltration, lipid oxidation and pancreatic tissue edema. Moreover, hydrogen-rich saline treatment could promote acinar cell proliferation, inhibit apoptosis and NF-{kappa}B activation. These results indicate that hydrogen treatment has a protective effect against AP, and the effect is possibly due to its ability to inhibit oxidative stress, apoptosis, NF-{kappa}B activation and to promote acinar cell proliferation.

    Background Tumor necrosis factor-alpha is a proinflammatory cytokine that has been implicated in the pathobiology of acute kidney injury (AKI). Methods We explored the association of a functional polymorphism in the promoter region (rs1800629) of the TNFA gene with severity of AKI, as defined by level of glomerular filtration (serum cystatin C and creatinine) and tubular injury (urinary NAG, KIM-1, α-GST, and π-GST) markers, in 262 hospitalized adults. Results In unadjusted analyses, compared with the GG genotype, the TNFA GA and AA genotype groups tended to have higher enrollment (p = 0.08), peak (p = 0.004), and discharge (p = 0.004) serum creatinine levels, and the AA genotype tended to have a higher enrollment serum cystatin C level (p = 0.04). Compared with the GG genotype, the TNFA GA and AA genotype groups tended to have a higher urinary KIM-1 level (p = 0.03), and the AA genotype group tended to have a higher urinary π-GST level (p = 0.03). After adjustment for sex, race, age, baseline estimated glomerular filtration rate, sepsis, and dialysis requirement, compared with the GG genotype, the TNFA minor A-allele group had a higher peak serum creatinine of 1.03 mg/dl (0.43, 1.63; p = 0.001) and a higher urinary KIM-1 (relative ratio: 1.73; 95% CI: 1.16, 2.59; p = 0.008). The TNFA minor A-allele group also had a higher Multiple Organ Failure score of 0.26 (95% CI: 0.03, 0.49; p = 0.024) after adjustment for sex, race, age, and sepsis. Conclusions The TNFA rs1800629 gene polymorphism is associated with markers of kidney disease severity and distant organ dysfunction among patients with AKI. Larger studies are needed to confirm these relationships. PMID:23796916

    The purpose of this study is to investigate the hypothesis that the mesenteric lymphatic system plays an important role in acute lung injury in a rat model induced by severe intraperitoneal infection. Male Wistar rats weighing 250∼300 g were randomly divided into 3 groups and subjected to sham operation, intraperitoneal infection, or mesenteric lymphatic drainage. The activity of diamine oxidase (DAO) and myeloperoxidase (MPO) were measured by enzymatic assay. The endotoxin levels in plasma, lymph, and bronchoalveolar lavage fluid (BALF) were evaluated using the limulus amoebocyte lysate reagent. The cytokines, adhesion factors, chemokines, and inflammatory factors were detected by ELISA. TLR-4, NF-kB, and IRAK-4 were analyzed by Western blotting. Compared with sham-operated rats, rats with intraperitoneal infection had increased MPO and decreased DAO activity in intestinal tissues. Mesenteric lymph drainage reduced the alterations in MPO and DAO activity induced by intraperitoneal infection. The MPO activity in pulmonary tissue and the permeability of pulmonary blood vessels were also increased, which were partially reversed by mesenteric lymph drainage. The endotoxin levels in lymphatic fluid and alveolar perfusion fluid were elevated after intraperitoneal infection but decreased to control levels after lymph drainage. No alterations in the levels of plasma endotoxin were observed. The number of neutrophils was increased in BALF and lymph in the infected rats, and was also reduced after drainage. Lymph drainage also decreased the levels of inflammatory cytokines, chemokines, and adhesion factors in the plasma, lymph, and BALF, as well as the levels of TLR-4, NF-kB, and IRAK-4 in pulmonary and intestinal tissues. The mesenteric lymphatic system is the main pathway involved in early lung injury caused by severe intraperitoneal infection, in which activation of the TLR-4 signal pathway may play a role.

    Background and study aim: The novel over-the-scope clip (OTSC) allows for excellent apposition of tissue, potentially permitting hemostasis to be achieved in various types of gastrointestinal lesions. This study aimed to evaluate the usefulness and safety of OTSCs for endoscopic hemostasis in patients with upper gastrointestinal bleeding in whom traditional endoscopic methods had failed. Patients and methods: A retrospective case series of all patients who underwent placement of an OTSC for severe recurrent upper gastrointestinal bleeding over a 14-month period was studied. Outcome data for the procedure included achievement of primary hemostasis, episodes of recurrent bleeding, and complications. Results: Twelve consecutive patients (67 % men; mean age 59, range 29 – 86) with ongoing upper gastrointestinal bleeding despite previous endoscopic management were included. They had a mean ASA score of 3 (range 2 – 4), a mean hemoglobin of 7.2 g/dL (range 5.2 – 9.1), and shock was present in 75 % of patients. They had all received packed red blood cells (mean 5.1 units, range 2 – 12). The etiology of bleeding was: duodenal ulcer (n = 6), gastric ulcer (n = 2) Dieulafoy lesion (n = 2), anastomotic ulceration (n = 1), Mallory – Weiss tear (n = 1). Hemostasis was achieved in all patients. Rebleeding occurred in two patients 1 day and 7 days after OTSC placement. There were no complications associated with OTSC application. Conclusions: OTSC use represents an effective, easily performed, and safe endoscopic therapy for various causes of severe acute gastrointestinal bleeding when conventional endoscopic techniques have failed. This therapy should be added to the armamentarium of therapeutic endoscopists. PMID:26134611

    In addition to members causing milder human infections, the Coronaviridae family includes potentially lethal zoonotic agents causing severe acute respiratory syndrome (SARS) and the recently emerged Middle East respiratory syndrome. The ∼30-kb positive-stranded RNA genome of coronaviruses encodes a replication/transcription machinery that is unusually complex and composed of 16 nonstructural proteins (nsps). SARS-CoV nsp12, the canonical RNA-dependent RNA polymerase (RdRp), exhibits poorly processive RNA synthesis in vitro, at odds with the efficient replication of a very large RNA genome in vivo. Here, we report that SARS-CoV nsp7 and nsp8 activate and confer processivity to the RNA-synthesizing activity of nsp12. Using biochemical assays and reverse genetics, the importance of conserved nsp7 and nsp8 residues was probed. Whereas several nsp7 mutations affected virus replication to a limited extent, the replacement of two nsp8 residues (P183 and R190) essential for interaction with nsp12 and a third (K58) critical for the interaction of the polymerase complex with RNA were all lethal to the virus. Without a loss of processivity, the nsp7/nsp8/nsp12 complex can associate with nsp14, a bifunctional enzyme bearing 3'-5' exoribonuclease and RNA cap N7-guanine methyltransferase activities involved in replication fidelity and 5'-RNA capping, respectively. The identification of this tripartite polymerase complex that in turn associates with the nsp14 proofreading enzyme sheds light on how coronaviruses assemble an RNA-synthesizing machinery to replicate the largest known RNA genomes. This protein complex is a fascinating example of the functional integration of RNA polymerase, capping, and proofreading activities. PMID:25197083

    Objective It has proved that muscle paralysis was more protective for injured lung in severe acute respiratory distress syndrome (ARDS), but the precise mechanism is not clear. The purpose of this study was to test the hypothesis that abdominal muscle activity during mechanically ventilation increases lung injury in severe ARDS. Methods Eighteen male Beagles were studied under mechanical ventilation with anesthesia. Severe ARDS was induced by repetitive oleic acid infusion. After lung injury, Beagles were randomly assigned into spontaneous breathing group (BIPAPSB) and abdominal muscle paralysis group (BIPAPAP). All groups were ventilated with BIPAP model for 8h, and the high pressure titrated to reached a tidal volume of 6ml/kg, the low pressure was set at 10 cmH2O, with I:E ratio 1:1, and respiratory rate adjusted to a PaCO2 of 35–60 mmHg. Six Beagles without ventilator support comprised the control group. Respiratory variables, end-expiratory volume (EELV) and gas exchange were assessed during mechanical ventilation. The levels of Interleukin (IL)-6, IL-8 in lung tissue and plasma were measured by qRT-PCR and ELISA respectively. Lung injury scores were determined at end of the experiment. Results For the comparable ventilator setting, as compared with BIPAPSB group, the BIPAPAP group presented higher EELV (427±47 vs. 366±38 ml) and oxygenation index (293±36 vs. 226±31 mmHg), lower levels of IL-6(216.6±48.0 vs. 297.5±71.2 pg/ml) and IL-8(246.8±78.2 vs. 357.5±69.3 pg/ml) in plasma, and lower express levels of IL-6 mRNA (15.0±3.8 vs. 21.2±3.7) and IL-8 mRNA (18.9±6.8 vs. 29.5±7.9) in lung tissues. In addition, less lung histopathology injury were revealed in the BIPAPAP group (22.5±2.0 vs. 25.2±2.1). Conclusion Abdominal muscle activity during mechanically ventilation is one of the injurious factors in severe ARDS, so abdominal muscle paralysis might be an effective strategy to minimize ventilator-induce lung injury.

    The Japanese guidelines for acute otitis media in children recommend classifying acute otitis media by age, manifestations and local findings, and also recommend myringotomy for moderate-grade cases with severe local findings, severe-grade cases, and treatment-resistant cases. The heptavalent pneumococcal conjugate vaccine was released in Japan in February 2010. In Hiroshima City, public funding allowing free inoculation with this vaccine was initiated from January 2011, and the number of vaccinated individuals has since increased dramatically. This study investigated changes in the number of myringotomies performed to treat acute otitis media during the 5-year period from January 2008 to December 2012 at two hospitals and five clinics in the Asa Area of Hiroshima City, Japan. A total of 3,165 myringotomies for acute otitis media were performed. The rate of procedures per child-year performed in <5-year-old children decreased by 29.1% in 2011 and by 25.2% in 2012 compared to the mean rate performed in the 3 years prior to the introduction of public funding. A total of 895 myringotomies were performed for 1-year-old infants. The rate of myringotomies per child-year performed for acute otitis media in 1-year-old infants decreased significantly in the 2 years after the introduction of public funding for heptavalent pneumococcal conjugate vaccine compared to all years before introduction (p<0.000001). Our results suggest a benefit of heptavalent pneumococcal conjugate vaccine for acute otitis media in reducing the financial burden of myringotomy. In addition, this vaccine may help prevent acute otitis media with severe middle ear inflammation in 1-year-old infants. PMID:26348230

    2016-01-01

    To date, there have been several systematic reviews with meta-analysis that have shown no reduction in mortality with the use of inhaled nitric oxide (iNO) in patients with acute respiratory distress syndrome (ARDS). Importantly, these reports fail to make a distinction between the pediatric and adult patient. The number of adult patients in these reviews are far greater than the number of pediatric patients, which makes it difficult to interpret the data regarding the role of iNO on the pediatric population. Extrapolating data from the adult population to the pediatric population is complicated as we know that physiology and the body’s response to disease can be different between adult and pediatric patients. iNO has been demonstrated to improve outcomes in term and near-term infants with hypoxic respiratory failure associated with pulmonary hypertension. Recently, Bronicki et al. published a prospective randomized control trial investigating the impact of iNO on the pediatric patient population with acute respiratory failure. In this study, a benefit of decreased duration of mechanical ventilation and an increased rate of ECMO-free survival was demonstrated in patients who were randomized to receiving iNO, suggesting that there may be benefit to the use of iNO in pediatric ARDS (PARDS) that has not been demonstrated in adults. iNO has repeatedly been shown to transiently improve oxygenation in all age groups, and yet neonates and pediatric patients have shown improvement in other outcomes that have not been seen in adults. The mechanism that explains improvement with the use of iNO in these patient populations are not well understood but does not appear to be solely a result of sustained improvement in oxygenation. There are physiologic studies that suggest alternative mechanisms for explaining the positive effects of iNO, such as platelet aggregation inhibition and reduction in systemic inflammation. Hence, the role of iNO by various mechanisms and in various

  19. Severe starvation-induced hepatocyte autophagy as a cause of acute liver injury in anorexia nervosa: a case report.

    PubMed

    Restellini, S; Spahr, L; Rubbia Brandt, L

    2013-01-01

    Introduction. Mild elevation of transaminase may be observed in anorexia nervosa, but acute liver injury is uncommon. A complex programmed cell death in response to starvation, called autophagy, has been described in experimental and human studies. Case Presentation. A 24-year-old woman suffering from anorexia nervosa was hospitalized for severe malnutrition. At admission, there were biological signs of acute liver injury but no electrolytic imbalance. After having ruled out the most common causes of liver injury, the patient was carefully refed. As liver tests remained abnormal, liver biopsy was performed. At histology and electron microscopy, numerous signs suggestive of starvation-induced hepatocyte autophagy were found. Discussion. Severe starvation can be associated with acute liver injury that is slowly reversible with careful enteral nutrition. In this clinical situation, profound hepatic glycogen depletion in association with autophagy appears as the leading cause of liver injury. PMID:25379300

    Neuromodulatory techniques have developed rapidly in the therapeutic management of refractory headaches. Invasive procedures comprise peripheral nerve stimulation (particularly occipital nerve stimulation), vagus nerve stimulation, cervical spinal cord stimulation and hypothalamic deep brain stimulation. Transcutaneous electrical nerve stimulation, repetitive transcranial magnetic stimulation and transcranial direct current stimulation are noninvasive variants. Based on current neuroimaging, neurophysiological and clinical studies occipital nerve stimulation and hypothalamic deep brain stimulation are recommended for patients with chronic cluster headache. Less convincing evidence can be found for their use in other refractory headaches such as chronic migraine. No clear recommendation can be given for the other neuromodulatory techniques. The emerging concept of intermittent stimulation of the sphenopalatine ganglion is nonetheless promising. Robust randomized and sham-controlled multicenter studies are needed before these therapeutic approaches are widely implemented. Due to the experimental nature all patients should be treated in clinical studies. It is essential to confirm the correct headache diagnosis and the refractory nature before an invasive approach is considered. Patients should generally be referred to specialized interdisciplinary outpatient departments which closely collaborate with neurosurgeons who are experienced in the implantation of neuromodulatory devices. It is crucial to ensure a competent postoperative follow-up with optimization of stimulation parameters and adjustment of medication. PMID:20972665

    Background Migraine headache significantly impacts the health of individuals and of society. The application of simple physical nonpharmacological techniques could greatly reduce the therapeutic costs and side effects in acute onset of such headaches. Methods Ten male patients (mean age was 32.0 ± 10.59 years) with acute onset of a migraine headache according to IHS-2004 diagnostic criteria were enrolled in the study. Neck and upper thoracic spine massage and manipulation technique was performed. Headache pain intensity was assessed before and after the intervention by means of a verbal analog scale. Results Following treatment, headache pain intensity was significantly reduced compared to the pretreatment values (1.85 ± 1.11 vs. 5.80 ± 2.25, p = .005). As a percentage, this represents a mean pain reduction of 68.77% ± 18.56. No side effects were observed, and all of the patients reported satisfaction with the intervention. Conclusion Our results show that the applied cervical and upper thoracic massage and manipulation technique could reduce the headache attack pain intensity in patients with migraine headaches, though further testing, including study designs that make use of control groups, is needed.

    AIM: To study the safety of epidural anesthesia (EA), its effect on pancreatic perfusion and the outcome of patients with acute pancreatitis (AP). METHODS: From 2005 to August 2010, patients with predicted severe AP [Ranson score ≥ 2, C-reactive protein > 100 or necrosis on computed tomography (CT)] were prospectively randomized to either a group receiving EA or a control group treated by patient controlled intravenous analgesia. Pain management was evaluated in the two groups every eight hours using the visual analog pain scale (VAS). Parameters for clinical severity such as length of hospital stay, use of antibiotics, admission to the intensive care unit, radiological/clinical complications and the need for surgical necrosectomy including biochemical data were recorded. A CT scan using a perfusion protocol was performed on admission and at 72 h to evaluate pancreatic blood flow. A significant variation in blood flow was defined as a 20% difference in pancreatic perfusion between admission and 72 h and was measured in the head, body and tail of the pancreas. RESULTS: We enrolled 35 patients. Thirteen were randomized to the EA group and 22 to the control group. There were no differences in demographic characteristics between the two groups. The Balthazar radiological severity score on admission was higher in the EA group than in the control group (mean score 4.15 ± 2.54 vs 3.38 ± 1.75, respectively, P = 0.347) and the median Ranson scores were 3.4 and 2.7 respectively (P = NS). The median duration of EA was 5.7 d, and no complications of the epidural procedure were reported. An improvement in perfusion of the pancreas was observed in 13/30 (43%) of measurements in the EA group vs 2/27 (7%) in the control group (P = 0.0025). Necrosectomy was performed in 1/13 patients in the EA group vs 4/22 patients in the control group (P = 0.63). The VAS improved during the first ten days in the EA group compared to the control group (0.2 vs 2.33, P = 0.034 at 10 d). Length

    Background Studying the uptake of 2-deoxy glucose (2-DG) analogs such as 2-Deoxy-2-[18F] fluoroglucose (FDG) is a common approach to identify and monitor malignancies and more recently chronic inflammation. While pancreatitis is a common cause for false positive results in human studies on pancreatic cancer using FDG, the relevance of these findings to acute pancreatitis (AP) is unknown. FDG has a short half-life. Thus, with an aim to accurately characterize the metabolic demand of the pancreas during AP in real-time, we studied the uptake of the non-radioactive, near infrared fluorescence labelled 2-deoxyglucose analog, IRDye® 800CW 2-DG probe (NIR 2-DG; Li-Cor) during mild and severe biliary AP. Methods Wistar rats (300 g; 8–12/group) were administered NIR 2-DG (10 nM; I.V.). Mild and severe biliary AP were respectively induced by biliopancreatic duct ligation (DL) alone or along with infusing glyceryl trilinoleate (GTL; 50 μL/100 g) within 10 minutes of giving NIR 2-DG. Controls (CON) only received NIR 2-DG. Imaging was done every 5–10 minutes over 3 hrs. Average Radiant Efficiency [p/s/cm²/sr]/[μW/cm²] was measured over the pancreas using the IVIS 200 in-vivo imaging system (PerkinElmer) using the Living Image® software and verified in ex vivo pancreata. Blood amylase, lipase and pancreatic edema, necrosis were measured over the course of AP. Results NIR 2-DG uptake over the first hour was not influenced by AP induction. However, while the signal declined in controls and rats with mild AP, there was significantly higher retention of NIR 2-DG in the pancreas after 1 hour in those with GTL pancreatitis. The increase was > 3 fold over controls in the GTL group and was verified to be in the pancreas ex vivo. In vitro, pancreatic acini exposed to GTL had a similar increase in NIR 2-DG uptake which was followed by progressively worse acinar necrosis. Greater retention of NIR 2-DG in vivo was associated with worse pancreatic necrosis, reduced ATP

    Purpose: The melanocortin-1 receptor (MC1R) regulates melanin biogenesis. Deoxyribonucleic acid sequence variants in the form of single nucleotide polymorphisms (SNPs) of MC1R affect melanin expression and are linked to skin phenotype. We aimed to determine whether SNPs of MC1R were associated with unexpectedly severe ionizing radiation reactions. Methods and Materials: The MC1R genotype of a cohort of Australians with unexpectedly severe acute and/or late reactions (Common Terminology Criteria Version 3 (CTCv3) Grade 3 or 4) to radiotherapy (RT) for cancer (n = 30) was analyzed. The findings were compared with control data from our previous study of MC1R representative of the general Australian population (n = 1,787). Results: The difference in frequency of alleles encoding a 'red hair color' phenotype in the cohort of patients with unexpectedly severe acute radiation reactions (n = 12) was significantly increased compared with the control population (p = 0.003). Acute radiosensitivity was especially associated with the R160W variant allele (odds ratio, 3.64 [95% confidence interval, 1.3-10.27]). The corresponding comparison of MC1R controls with unexpectedly severe late radiation reactions (n = 18) was not significant. It was also found that R160W as a part of the genotype in the patients with unexpectedly severe acute RT side effects as compared with the control group was also significant (p = 0.043). Conclusions: In this small cohort of cancer patients, deoxyribonucleic acid sequence variants of the MC1R gene, especially the R160W variant, have been associated with unexpectedly severe acute reactions to RT. This result needs to be verified in a larger cohort of patients.

    Giant cell arteritis (GCA), a type of systemic arteritis, is rare in Japan. We herein report a case of acute myeloid leukemia (AML) complicated by GCA that manifested during chemotherapy for AML. A 77-year-old woman with severe back pain was diagnosed with AML. She achieved complete remission with the resolution of her back pain following induction chemotherapy. However, she developed a headache and fever after consolidation chemotherapy. A diagnosis of GCA was made based on a biopsy of the temporal artery and arterial imaging. GCA should therefore be included in the differential diagnosis in AML patients complicated with a headache and fever of unknown origin. PMID:26831026

    2012-01-01

    Background Prognostic assessment is important for the management of patients with acute pulmonary embolism (APE). Pulmonary Embolism Severity Index (PESI) and simple PESI (sPESI) are new emerged prognostic assessment tools for APE. The aim of this meta-analysis is to assess the accuracy of the PESI and the sPESI to predict prognostic outcomes (all-cause and PE-related mortality, serious adverse events) in APE patients, and compare between these two PESIs. Methods MEDLINE and EMBASE database were searched up to June 2012 using the terms “Pulmonary Embolism Severity Index” and “pulmonary embolism”. Summary odds ratio (OR) with 95% confidence intervals (CIs) for prognostic outcomes in low risk PESI versus high risk PESI were calculated. Summary receiver operating characteristic curve (SROC) used to estimate overall predicting accuracies of prognostic outcomes. Results Twenty-one studies were included in this meta-analysis. The results showed low-risk PESI was significantly associated with lower all-cause mortality (OR 0.13; 95% CI 0.12 to 0.15), PE-related mortality (OR 0.09; 95% CI 0.05 to 0.17) and serious adverse events (OR 0.34; 95% CI 0.29 to 0.41), with no homogeneity across studies. In sPESI subgroup, the OR of all-cause mortality, PE-related mortality, and serious adverse events was 0.10 (95% CI 0.08 to 0.14), 0.09 (95% CI 0.03 to 0.26) and 0.40 (95% CI 0.31 to 0.51), respectively; while in PESI subgroup, the OR was 0.14 (95% CI 0.13 to 0.16), 0.09 (95% CI 0.04 to 0.21), and 0.30 (95% CI 0.23 to 0.38), respectively. For accuracy analysis, the pooled sensitivity, the pooled specificity, and the overall weighted AUC for PESI predicting all-cause mortality was 0.909 (95% CI: 0.900 to 0.916), 0.411 (95% CI: 0.407 to 0.415), and 0.7853±0.0058, respectively; for PE-related mortality, it was 0.953 (95% CI: 0.913 to 0.978), 0.374 (95% CI: 0.360 to 0.388), and 0.8218±0.0349, respectively; for serious adverse events, it was 0.821 (95% CI: 0.795 to 0.845), 0

    The bacterial component of the human gut microbiota undergoes a definable program of postnatal development. Evidence is accumulating that this program is disrupted in children with severe acute malnutrition (SAM) and that their persistent gut microbiota immaturity, which is not durably repaired with current ready-to-use therapeutic food (RUTF) interventions, is causally related to disease pathogenesis. To further characterize gut microbial community development in healthy versus malnourished infants/children, we performed a time-series metagenomic study of DNA isolated from virus-like particles (VLPs) recovered from fecal samples collected during the first 30 mo of postnatal life from eight pairs of mono- and dizygotic Malawian twins concordant for healthy growth and 12 twin pairs discordant for SAM. Both members of discordant pairs were sampled just before, during, and after treatment with a peanut-based RUTF. Using Random Forests and a dataset of 17,676 viral contigs assembled from shotgun sequencing reads of VLP DNAs, we identified viruses that distinguish different stages in the assembly of the gut microbiota in the concordant healthy twin pairs. This developmental program is impaired in both members of SAM discordant pairs and not repaired with RUTF. Phage plus members of the Anelloviridae and Circoviridae families of eukaryotic viruses discriminate discordant from concordant healthy pairs. These results disclose that apparently healthy cotwins in discordant pairs have viromes associated with, although not necessarily mediators, of SAM; as such, they provide a human model for delineating normal versus perturbed postnatal acquisition and retention of the gut microbiota's viral component in populations at risk for malnutrition.

    Background Although malnutrition affects thousands of children throughout the Sahel each year and predisposes them to infections, there is little data on the etiology of infections in these populations. We present a clinical and biological characterization of infections in hospitalized children with complicated severe acute malnutrition (SAM) in Maradi, Niger. Methods Children with complicated SAM hospitalized in the intensive care unit of a therapeutic feeding center, with no antibiotics in the previous 7 days, were included. A clinical examination, blood, urine and stool cultures, and chest radiography were performed systematically on admission. Results Among the 311 children included in the study, gastroenteritis was the most frequent clinical diagnosis on admission, followed by respiratory tract infections and malaria. Blood or urine culture was positive in 17% and 16% of cases, respectively, and 36% had abnormal chest radiography. Enterobacteria were sensitive to most antibiotics, except amoxicillin and cotrimoxazole. Twenty-nine (9%) children died, most frequently from sepsis. Clinical signs were poor indicators of infection and initial diagnoses correlated poorly with biologically or radiography-confirmed diagnoses. Conclusions These data confirm the high level of infections and poor correlation with clinical signs in children with complicated SAM, and provide antibiotic resistance profiles from an area with limited microbiological data. These results contribute unique data to the ongoing debate on the use and choice of broad-spectrum antibiotics as first-line treatment in children with complicated SAM and reinforce the call for an update of international guidelines on management of complicated SAM based on more recent data.

    The aim of this study was to determine the influence of severe acute hypoxia on muscle activation during whole body dynamic exercise. Eleven young men performed four incremental cycle ergometer tests to exhaustion breathing normoxic (FIO2=0.21, two tests) or hypoxic gas (FIO2=0.108, two tests). Surface electromyography (EMG) activities of rectus femoris (RF), vastus medialis (VL), vastus lateralis (VL), and biceps femoris (BF) were recorded. The two normoxic and the two hypoxic tests were averaged to reduce EMG variability. Peak VO2 was 34% lower in hypoxia than in normoxia (p<0.05). The EMG root mean square (RMS) increased with exercise intensity in all muscles (p<0.05), with greater effect in hypoxia than in normoxia in the RF and VM (p<0.05), and a similar trend in VL (p=0.10). At the same relative intensity, the RMS was greater in normoxia than in hypoxia in RF, VL, and BF (p<0.05), with a similar trend in VM (p=0.08). Median frequency increased with exercise intensity (p<0.05), and was higher in hypoxia than in normoxia in VL (p<0.05). Muscle contraction burst duration increased with exercise intensity in VM and VL (p<0.05), without clear effects of FIO2. No significant FIO2 effects on frequency domain indices were observed when compared at the same relative intensity. In conclusion, muscle activation during whole body exercise increases almost linearly with exercise intensity, following a muscle-specific pattern, which is adjusted depending on the FIO2 and the relative intensity of exercise. Both VL and VM are increasingly involved in power output generation with the increase of intensity and the reduction in FIO2. PMID:25225839

    Children with severe acute malnutrition (SAM) with complications require in-patient management including therapeutic feeding. Little attention has been given to the effects of these feeds on the essential fatty acid status of children with SAM. The objective of this study was to describe changes in the PUFA composition in whole blood in children with SAM during treatment and to determine predictors of change. This prospective study took place in a paediatric nutrition rehabilitation unit in Kampala, Uganda, and assessed whole-blood fatty acid composition of children with SAM at admission, transition, discharge and follow-up (8 and 16 weeks). ANCOVA was used to identify predictors of change in whole-blood PUFA. The study included 120 children with SAM and twenty-nine healthy control children of similar age and sex. Among the SAM children, 38 % were female and 64 % had oedema. Whole-blood n-6 PUFA proportions increased from admission to follow-up, except for arachidonic acid, which decreased by 0·79 (95 % CI 0·46, 1·12) fatty acid percentage (FA%) from admission to transition and 0·10 (95 % CI 0·23, 0·44) FA% at discharge. n-3 Long-chain (LC) PUFA decreased by 0·21 (95 % CI 0·03, 0·40) FA% at discharge and 0·22 (95 % CI 0·01, 0·42) FA% at 8 weeks of follow-up. This decrease was greater in children from families with recent fish intake and those with nasogastric tube feeding. Current therapeutic feeds do not correct whole-blood levels of LCPUFA, particularly n-3 LCPUFA, in children with SAM. Increased attention is needed to the contents of n-3 LCPUFA in therapeutic feeds.

    AIM: To investigate the effects of early enteral nutrition (EEN) on the immune function and clinical outcome of patients with severe acute pancreatitis (SAP). METHODS: Patients were randomly allocated to receive EEN or delayed enteral nutrition (DEN). Enteral nutrition was started within 48 h after admission in EEN group, whereas from the 8th day in DEN group. All the immunologic parameters and C-reactive protein (CRP) levels were collected on days 1, 3, 7 and 14 after admission. The clinical outcome variables were also recorded. RESULTS: Sixty SAP patients were enrolled to this study. The CD4+ T-lymphocyte percentage, CD4+/CD8+ ratio, and the CRP levels in EEN group became significantly lower than in DEN group from the 7th day after admission. In contrast, the immunoglobulin G (IgG) levels and human leukocyte antigen-DR expression in EEN group became significantly higher than in DEN group from the 7th day after admission. No difference of CD8+ T-lymphocyte percentage, IgM and IgA levels was found between the two groups. The incidences of multiple organ dysfunction syndrome, systemic inflammatory response syndrome, and pancreatic infection as well as the duration of intensive care unit stay were significantly lower in EEN group than in DEN group. However, there was no difference of hospital mortality between the two groups. CONCLUSION: EEN moderates the excessive immune response during the early stage of SAP without leading to subsequent immunosuppression. EEN can improve the clinical outcome, but not decrease the hospital mortality of SAP patients. PMID:23431120

  3. Mechanisms of Host Receptor Adaptation by Severe Acute Respiratory Syndrome Coronavirus

    2012-12-10

    The severe acute respiratory syndrome coronavirus (SARS-CoV) from palm civets has twice evolved the capacity to infect humans by gaining binding affinity for human receptor angiotensin-converting enzyme 2 (ACE2). Numerous mutations have been identified in the receptor-binding domain (RBD) of different SARS-CoV strains isolated from humans or civets. Why these mutations were naturally selected or how SARS-CoV evolved to adapt to different host receptors has been poorly understood, presenting evolutionary and epidemic conundrums. In this study, we investigated the impact of these mutations on receptor recognition, an important determinant of SARS-CoV infection and pathogenesis. Using a combination of biochemical, functional, and crystallographic approaches, we elucidated the molecular and structural mechanisms of each of these naturally selected RBD mutations. These mutations either strengthen favorable interactions or reduce unfavorable interactions with two virus-binding hot spots on ACE2, and by doing so, they enhance viral interactions with either human (hACE2) or civet (cACE2) ACE2. Therefore, these mutations were viral adaptations to either hACE2 or cACE2. To corroborate the above analysis, we designed and characterized two optimized RBDs. The human-optimized RBD contains all of the hACE2-adapted residues (Phe-442, Phe-472, Asn-479, Asp-480, and Thr-487) and possesses exceptionally high affinity for hACE2 but relative low affinity for cACE2. The civet-optimized RBD contains all of the cACE2-adapted residues (Tyr-442, Pro-472, Arg-479, Gly-480, and Thr-487) and possesses exceptionally high affinity for cACE2 and also substantial affinity for hACE2. These results not only illustrate the detailed mechanisms of host receptor adaptation by SARS-CoV but also provide a molecular and structural basis for tracking future SARS-CoV evolution in animals.

    Background Sonothrombolysis is safe and may increase the likelihood of early recanalization in acute ischemic stroke (AIS) patients Aims In preparation of a phase III clinical trial, we contrast the likelihood of achieving a sustained recanalization and functional independence in a post-hoc subgroup analysis of patients randomized to transcranial Doppler monitoring plus intravenous (IV) tPA (sonothrombolysis) compared to IV tPA alone in the CLOTBUST trial Methods We analyzed the data from all randomized AIS patients with pre-treatment NIHSS scores ≥10 points and proximal intracranial occlusions in the CLOTBUST trial. We compared sustained complete recanalization rate (TIBI flow grades 4-5) and functional independence (modified Rankin Scale [mRS] 0-1) at 90 days. Safety was evaluated by the rate of symptomatic intracranial hemorrhage (ICH) within 72 hours of stroke-onset Results Of 126 patients, a total of 85 AIS patients met our inclusion criteria: mean age 71±11years, 56% men, median NIHSS 17 (interquartile range 14-20). Of these patients, 41 (48%) and 44 (52%) were randomized to IV tPA alone and sonothrombolysis, respectively. More patients achieved sustained complete recanalization in the sonothrombolysis than in the IV tPA alone group (38.6% vs. 17.1%; p=0.032). Functional independence at 90 days was more frequently achieved in the sonothrombolysis than in the IV tPA alone group (37.2% vs. 15.8%; p=0.045). Symptomatic ICH rate was similar in both groups (4.9% vs. 4.6%; p=1.00) Conclusions Our results point to a signal of efficacy and provide information to guide the subsequent phase III randomized trial of sonothrombolysis in patients with severe ischemic strokes PMID:25079049

    Background: Organophosphorus pesticide poisoning kills around 200,000 people each year, principally due to self poisoning in the Asia-Pacific region. Aim: We wished to assess whether patients at high risk of death could be identified accurately using clinical parameters soon after hospital admission. Design: We evaluated the usefulness of the International Program on Chemical Safety Poison Severity Score (IPCS PSS) and the Glasgow Coma Score (GCS) prospectively for predicting death in patients poisoned by organophosphorus pesticides. Methods: Data were collected as part of a multicentre cohort study in Sri Lanka. Study doctors saw all patients on admission, collecting data on pulse, blood pressure, pupil size, need for intubation, and GCS. Results: 1365 patients with a history of acute organophosphorus poisoning were included. Receiver operating characteristic (ROC) curves were calculated for the IPCS PSS and GCS on admission. The IPCS PSS and GCS had similar ROC area under the curves (AUC) and best cut points as determined by Youden's index (AUC/sensitivity/specificity 0.81/0.78/0.79 for IPCS PSS ≥ grade 2 and 0.84/0.79/0.79 for GCS ≤13). The predictive value varied with the pesticide ingested, being more accurate for dimethoate poisoning and less accurate for fenthion poisoning (GCS AUC 0.91 compared to 0.69). Conclusions: GCS and the IPCS PSS were similarly effective at predicting outcome. Patients presenting with a GCS ≤ 13 need intensive monitoring and treatment. However, the identity of the organophosphate must be taken into account since the half of all patients who died from fenthion poisoning only had mild symptoms at presentation. PMID:18319295

    Although the finding of severe acute respiratory syndrome coronavirus (SARS-CoV) in caged palm civets from live animal markets in China has provided evidence for interspecies transmission in the genesis of the SARS epidemic, subsequent studies suggested that the civet may have served only as an amplification host for SARS-CoV. In a surveillance study for CoV in noncaged animals from the wild areas of the Hong Kong Special Administration Region, we identified a CoV closely related to SARS-CoV (bat-SARS-CoV) from 23 (39%) of 59 anal swabs of wild Chinese horseshoe bats (Rhinolophus sinicus) by using RT-PCR. Sequencing and analysis of three bat-SARS-CoV genomes from samples collected at different dates showed that bat-SARS-CoV is closely related to SARS-CoV from humans and civets. Phylogenetic analysis showed that bat-SARS-CoV formed a distinct cluster with SARS-CoV as group 2b CoV, distantly related to known group 2 CoV. Most differences between the bat-SARS-CoV and SARS-CoV genomes were observed in the spike genes, ORF 3 and ORF 8, which are the regions where most variations also were observed between human and civet SARS-CoV genomes. In addition, the presence of a 29-bp insertion in ORF 8 of bat-SARS-CoV genome, not in most human SARS-CoV genomes, suggests that it has a common ancestor with civet SARS-CoV. Antibody against recombinant bat-SARS-CoV nucleocapsid protein was detected in 84% of Chinese horseshoe bats by using an enzyme immunoassay. Neutralizing antibody to human SARS-CoV also was detected in bats with lower viral loads. Precautions should be exercised in the handling of these animals. PMID:16169905

    Severe acute respiratory syndrome (SARS) is an infectious and highly contagious disease that is caused by SARS coronavirus (SARS-CoV) and for which there are currently no approved treatments. We report the discovery and characterization of small-molecule inhibitors of SARS-CoV replication that block viral entry by three different mechanisms. The compounds were discovered by screening a chemical library of compounds for blocking of entry of HIV-1 pseudotyped with SARS-CoV surface glycoprotein S (SARS-S) but not that of HIV-1 pseudotyped with vesicular stomatitis virus surface glycoprotein G (VSV-G). Studies on their mechanisms of action revealed that the compounds act by three distinct mechanisms: (i) SSAA09E2 {N-[[4-(4-methylpiperazin-1-yl)phenyl]methyl]-1,2-oxazole-5-carboxamide} acts through a novel mechanism of action, by blocking early interactions of SARS-S with the receptor for SARS-CoV, angiotensin converting enzyme 2 (ACE2); (ii) SSAA09E1 {[(Z)-1-thiophen-2-ylethylideneamino]thiourea} acts later, by blocking cathepsin L, a host protease required for processing of SARS-S during viral entry; and (iii) SSAA09E3 [N-(9,10-dioxo-9,10-dihydroanthracen-2-yl)benzamide] also acts later and does not affect interactions of SARS-S with ACE2 or the enzymatic functions of cathepsin L but prevents fusion of the viral membrane with the host cellular membrane. Our work demonstrates that there are at least three independent strategies for blocking SARS-CoV entry, validates these mechanisms of inhibition, and introduces promising leads for the development of SARS therapeutics.

    Severe acute respiratory syndrome (SARS) is a highly contagious and life-threatening disease that emerged in China in November 2002. A novel SARS-associated coronavirus was identified as its principal etiologic agent; however, the immunopathogenesis of SARS and the role of special CTLs in virus clearance are still largely uncharacterized. In this study, potential HLA-A*0201-restricted spike (S) and nucleocapsid protein-derived peptides were selected from an online database and screened for potential CTL epitopes by in vitro refolding and T2 cell-stabilization assays. The antigenicity of nine peptides which could refold with HLA-A*0201 molecules was assessed with an IFN-gamma ELISPOT assay to determine the capacity to stimulate CTLs from PBMCs of HLA-A2(+) SARS-recovered donors. A novel HLA-A*0201-restricted decameric epitope P15 (S411-420, KLPDDFMGCV) derived from the S protein was identified and found to localize within the angiotensin-converting enzyme 2 receptor-binding region of the S1 domain. P15 could significantly enhance the expression of HLA-A*0201 molecules on the T2 cell surface, stimulate IFN-gamma-producing CTLs from the PBMCs of former SARS patients, and induce specific CTLs from P15-immunized HLA-A2.1 transgenic mice in vivo. Furthermore, significant P15-specific CTLs were induced from HLA-A2.1-transgenic mice immunized by a DNA vaccine encoding the S protein; suggesting that P15 was a naturally processed epitope. Thus, P15 may be a novel SARS-associated coronavirus-specific CTL epitope and a potential target for characterization of virus control mechanisms and evaluation of candidate SARS vaccines.

    There are many options for acute migraine attack treatment, but none is ideal for all patients. This study aims to review current medical office-based acute migraine therapy in adults and provides readers with an organized approach to this important facet of migraine treatment. A general literature review includes a review of several recent published guidelines. Acetaminophen, 4 nonsteroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, acetylsalicylic acid [ASA], naproxen sodium, and diclofenac potassium), and 7 triptans (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan, and zolmitriptan) have good evidence for efficacy and form the core of acute migraine treatment. NSAID-triptan combinations, dihydroergotamine, non-opioid combination analgesics (acetaminophen, ASA, and caffeine), and several anti-emetics (metoclopramide, domperidone, and prochlorperazine) are additional evidence-based options. Opioid containing combination analgesics may be helpful in specific patients, but should not be used routinely. Clinical features to be considered when choosing an acute migraine medication include usual headache intensity, usual rapidity of pain intensity increase, nausea, vomiting, degree of disability, patient response to previously used medications, history of headache recurrence with previous attacks, and the presence of contraindications to specific acute medications. Available acute medications can be organized into 4 treatment strategies, including a strategy for attacks of mild to moderate severity (strategy one: acetaminophen and/or NSAIDs), a triptan strategy for patients with severe attacks and for attacks not responding to strategy one, a refractory attack strategy, and a strategy for patients with contraindications to vasoconstricting drugs. Acute treatment of migraine attacks during pregnancy, lactation, and for patients with chronic migraine is also discussed. In chronic migraine, it is particularly important that medication

    Mitral regurgitation (MR) of even mild severity affects the prognosis of patients with acute coronary syndrome (ACS). The present study retrospectively analyzed 1,142 patients with ACS and MR of varying severity. Of the 95 patients with severe MR, 57 (60%) underwent primary percutaneous coronary intervention only and 38 (40%) underwent coronary artery bypass grafting (CABG) and mitral valve replacement (MVR). The severity of MR was significantly associated with the risk of heart failure but not with in-hospital or long-term mortality. In patients with severe MR, in-hospital mortality was no greater in those treated with CABG and MVR than in those treated with percutaneous coronary intervention alone. However, the incidence of long-term hard events (heart failure and all-cause mortality) was lower in those who had received the combined treatment. Multivariate analysis showed that, compared to percutaneous coronary intervention alone, CABG combined with MVR at the acute phase of ACS resulted in a significantly improved prognosis (odds ratio 0.172, 95% confidence interval 0.046 to 0.649, p = 0.009), even after adjusting for age, left ventricular filling pressure, and ejection fraction. In conclusion, the severity of MR in patients with ACS is associated with long-term heart failure events. Even at the acute phase of ACS, CABG combined with MVR results in an acceptable in-hospital mortality rate. The combined strategy also reduced the long-term hard events. PMID:22640972

    Angiotensin-converting enzyme 2 (ACE2) is a receptor for SARS-CoV, the novel coronavirus that causes severe acute respiratory syndrome [Li, W. Moore, M. J., Vasilieva, N., Sui, J., Wong, S. K., Berne, M. A., Somasundaran, M., Sullivan, J. L., Luzuriaga, K., Greenough, T. C., et al. (2003) Nature 426, 450–454]. We have identified a different human cellular glycoprotein that can serve as an alternative receptor for SARS-CoV. A human lung cDNA library in vesicular stomatitis virus G pseudotyped retrovirus was transduced into Chinese hamster ovary cells, and the cells were sorted for binding of soluble SARS-CoV spike (S) glycoproteins, S590 and S1180. Clones of transduced cells that bound SARS-CoV S glycoprotein were inoculated with SARS-CoV, and increases in subgenomic viral RNA from 1–16 h or more were detected by multiplex RT-PCR in four cloned cell lines. Sequencing of the human lung cDNA inserts showed that each of the cloned cell lines contained cDNA that encoded human CD209L, a C-type lectin (also called L-SIGN). When the cDNA encoding CD209L from clone 2.27 was cloned and transfected into Chinese hamster ovary cells, the cells expressed human CD209L glycoprotein and became susceptible to infection with SARS-CoV. Immunohistochemistry showed that CD209L is expressed in human lung in type II alveolar cells and endothelial cells, both potential targets for SARS-CoV. Several other enveloped viruses including Ebola and Sindbis also use CD209L as a portal of entry, and HIV and hepatitis C virus can bind to CD209L on cell membranes but do not use it to mediate virus entry. Our data suggest that the large S glycoprotein of SARS-CoV may use both ACE2 and CD209L in virus infection and pathogenesis. PMID:15496474

    Headache either as an isolated syndrome or as part of a symptomatic grouping is a frequent reason for medical consultation or hospitalization during childhood and adolescence. We review 94 clinical histories of patients between three and thirteen years of age. Headache was the reason for being hospitalized in all cases. Our aim was to assess its incidence rate, epidemiology, clinical characteristics and etiology in addition to evaluating as to whether complementary examinations carried out during hospitalization were worthwhile. Among the most significant results were the following: age (73 patients were over seven years old, 77.6%), time elapsed for symptomatology to evolve (exactly or less than one week in 45% of cases); family history of migraine in 55 cases (58.5%). The most frequent accompanying symptoms were vomiting (38.2%), nausea (22.3%) and abdominal pain (19.1%). Physical exam was normal in 63 cases (67%) while sixteen patients (17%) had neurological focal signs and/or signs of endocranial hypertension (ECHT). Electroencephalography was performed on 94.6% of the patients and proved pathological in 22 cases (25%). Brain computerized tomography (CT) scan was carried out on 92.5% of the patients with space occupying lesions in 3.2% of the cases. The most frequent final diagnosis (52% of patients) was one of migraine. We did not find any patients with intracranial expansionary processes not showing signs of ECHT and/or neurological focalization, for which reason we doubt the profitability of the almost routine practice of carrying out brain CT scan on patients when severe headache is the sole symptom and where there are no specific findings during physical examination.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7497236

    The case of a 58-year-old man with chronic paroxysmal headache and facial ecchymosis is described. The headache was pulsating, of short duration, without nausea or vomiting, and occasionally associated with flashing lights. Ecchymoses were mainly located in the middle forehead region and their appearance was associated with a reduction in intensity of the headache. Blood coagulation tests were within normal limits, and a skin biopsy of the ecchymotic lesion ruled out an underlying vasculitis. These attacks were difficult to include in any particular type of headache, although some aspects were similar to migraine headache. The possible mechanism of hemorrhages is discussed. PMID:8869770

    Purpose: Radiation therapy (RT) causes acute and late toxicities that affect various organs and functions. In a large cohort of patients treated with RT for localized head and neck cancer (HNC), we prospectively assessed the occurrence of RT-induced acute and late toxicities and identified characteristics that predicted these toxicities. Methods and Materials: We conducted a randomized trial among 540 patients treated with RT for localized HNC to assess whether vitamin E supplementation could improve disease outcomes. Adverse effects of RT were assessed using the Radiation Therapy Oncology Group Acute Radiation Morbidity Criteria during RT and one month after RT, and the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer Late Radiation Morbidity Scoring Scheme at six and 12 months after RT. The most severe adverse effect among the organs/tissues was selected as an overall measure of either acute or late toxicity. Grade 3 and 4 toxicities were considered as severe. Stepwise multivariate logistic regression models were used to identify all independent predictors (p < 0.05) of acute or late toxicity and to estimate odds ratios (OR) for severe toxicity with their 95% confidence intervals (CI). Results: Grade 3 or 4 toxicity was observed in 23% and 4% of patients, respectively, for acute and late toxicity. Four independent predictors of severe acute toxicity were identified: sex (female vs. male: OR = 1.72, 95% confidence interval [CI]: 1.06-2.80), Karnofsky Performance Status (OR = 0.67 for a 10-point increment, 95% CI: 0.52-0.88), body mass index (above 25 vs. below: OR = 1.88, 95% CI: 1.22-2.90), TNM stage (Stage II vs. I: OR = 1.91, 95% CI: 1.25-2.92). Two independent predictors were found for severe late toxicity: female sex (OR = 3.96, 95% CI: 1.41-11.08) and weight loss during RT (OR = 1.26 for a 1 kg increment, 95% CI: 1.12-1.41).

    In pancreatic acinar cells, the Src family of kinases (SFK) is involved in the activation of several signaling cascades that are implicated in mediating cellular processes (growth, cytoskeletal changes, apoptosis). However, the role of SFKs in various physiological responses such as enzyme secretion or in pathophysiological processes such as acute pancreatitis is either controversial, unknown, or incompletely understood. To address this, in this study, we investigated the role/mechanisms of SFKs in acute pancreatitis and enzyme release. Enzyme secretion was studied in rat dispersed pancreatic acini, in vitro acute-pancreatitis-like changes induced by supramaximal COOH-terminal octapeptide of cholecystokinin (CCK). SFK involvement assessed using the chemical SFK inhibitor (PP2) with its inactive control, 4-amino-7-phenylpyrazol[3,4-d]pyrimidine (PP3), under experimental conditions, markedly inhibiting SFK activation. In CCK-stimulated pancreatic acinar cells, activation occurred of trypsinogen, various MAP kinases (p42/44, JNK), transcription factors (signal transducer and activator of transcription-3, nuclear factor-κB, activator protein-1), caspases (3, 8, and 9) inducing apoptosis, LDH release reflective of necrosis, and various chemokines secreted (monocyte chemotactic protein-1, macrophage inflammatory protein-1α, regulated on activation, normal T cell expressed and secreted). All were inhibited by PP2, not by PP3, except caspase activation leading to apoptosis, which was increased, and trypsin activation, which was unaffected, as was CCK-induced amylase release. These results demonstrate SFK activation is playing a dual role in acute pancreatitis, inhibiting apoptosis and promoting necrosis as well as chemokine/cytokine release inducing inflammation, leading to more severe disease, as well as not affecting secretion. Thus, our studies indicate that SFK is a key mediator of inflammation and pancreatic acinar cell death in acute pancreatitis, suggesting it

    A male, 34 years of age, suffers from headaches, red and watery eyes. The headaches began in childhood; the frequency of headaches has increased over the years and in the last decade headaches have occurred on a daily basis. If he wakes up before sunrise he feels much better and free of a headache; however, once he continues to sleep during and after sunrise, he suffers from tiredness, headache and nervousness. On magnetic resonance imaging (MRI), benign neuroepithelial cysts or a chronic infarct area was reported at the junction of the left medio-lateral zone of hypothalamus. After repeated MRI examinations, it was decided that the lesion on the left medio-lateral zone of hypothalamus may have disrupted the pineal gland and changed melatonin secretion. It was decided to treat him with 3 mg melatonin daily before going to bed. After a week of treatment, the patient reported that he felt very fresh and was virtually free of headaches. PMID:19473198

    Headache attributed to head and/or neck trauma or injury, the so-called post-traumatic headache (PTH), is the most common secondary headache disorder and one of the most controversial clinical entities in the headache field, due to its unclear pathophysiological mechanisms and the unsolved role of associated psychological and medico-legal aspects. PTH, as a significant cause of morbidity after traumatic brain injury, may occur as an isolated symptom or as one of a constellation of symptoms known as post-concussive syndrome. However, in many cases, PTH might also represent an accentuation of non-disabling, remote or infrequent pre-existing primary headaches rather than a new onset headache strictly related to the trauma. Recently, the International Classification of Headache Disorders attempted to classify PTH; however, many unsolved issues are still to be clarified. In this brief review, we will focus on PTH clinical aspects and diagnostic criteria. PMID:24867854

    We describe a male infant with carnitine palmitoyltransferase 2 (CPT2) deficiency who presented with acute encephalopathy related to human herpesvirus-6 (HHV-6) infection. He was hospitalized for pylexia and status epilepticus, diagnosed with acute encephalopathy, and treated with intensive supportive care including mechanical ventilation, support for hypothermia, and control of the intracranial pressure, that caused severe neurological sequelae. HHV-6 was detected in his cerebrospinal fluid, indicating HHV-6 related encephalopathy. In the acute phase, acylcarnitine analysis of blood suggested a defect of long chain fatty acid β-oxidation, and CPT2 deficiency was genetically confirmed. In addition, other gene alterations that have been previously reported as "thermolabile variants" were found. Some patients with the infantile form of CPT2 deficiency present with acute encephalopathy, but others do not develop encephalopathy. The correlation between phenotype and genotype has not been clarified. Our case may contribute to the elucidation of the genetic factor involved in acute encephalopathy in CPT2 deficiency.

    Spontaneous intracranial hypotension (SIH) is an uncommon condition associated with postural headache, nausea and dizziness. It is believed to be secondary to a dural tear with resultant cerebrospinal fluid (CSF) leak. This is a case report of a pregnant woman (gestational age 31 weeks) who contacted an obstetric department because of severe headache. Pre-eclamp-sia was suspected, but not found. An MRI showed a CSF leak at C1-C2 level and intracranial signs of SIH. The woman was treated with an autologous blood patch and recovered quickly. Focus on subjective symptoms and MRI findings seem to be important in the diagnostic procedure of SIH. PMID:25352082

    Background Current (1999) World Health Organization guidelines recommend giving routine antibiotics (AB) for all children with severe acute malnutrition (SAM), even if they have uncomplicated disease with no clinically obvious infections. We examined the evidence behind this recommendation. Methods and Findings OVID-MEDLINE, EMBASE, COCHRANE, GLOBAL-HEALTH, CINAHL, POPLINE, AFRICA-WIDE-NiPAD, and LILACS were searched for AB efficacy, bacterial resistance, and infection rates in SAM. Following PRISMA guidelines, a systematic review and meta-analysis were performed. Three randomised controlled trials (RCT), five Cochrane reviews, and 37 observational studies were identified. One cohort-study showed no increase in nutritional-cure and mortality in uncomplicated SAM where no AB were used. (p>0.05). However, an unpublished RCT in this setting did show mortality benefits. Another RCT did not show superiority of ceftriaxone over amoxicilllin for these same outcomes, but adressed SAM children with and without complications (p = 0.27). Another RCT showed no difference between amoxicillin and cotrimoxazole efficacies for pneumonia in underweight, but not SAM. Our meta-analysis of 12 pooled susceptibility-studies for all types of bacterial isolates, including 2767 stricly SAM children, favoured amoxicillin over cotrimoxazole for susceptibility medians: 42% (IQR 27–55%) vs 22% (IQR 17–23%) and population-weighted-means 52.9% (range 23–57%) vs 35.4% (range 6.7–42%). Susceptibilities to second-line AB were better, above 80%. Prevalence of serious infections in SAM, pooled from 24 studies, ranged from 17% to 35.2%. No study infered any association of infection prevalence with AB regimens in SAM. Conclusions The evidence underlying current antibiotic recommendations for uncomplicated SAM is weak. Susceptibility-studies favour amoxicillin over cotrimoxazole. However, given that these antibiotics have side-effects, costs, and risks as well as benefits, their routine use

    Introduction Data on the burden and risk groups for influenza-associated mortality from Africa are limited. We aimed to estimate the incidence and risk-factors for in-hospital influenza-associated severe acute respiratory illness (SARI) deaths. Methods Hospitalised patients with SARI were enrolled prospectively in four provinces of South Africa from 2009–2013. Using polymerase chain reaction, respiratory samples were tested for ten respiratory viruses and blood for pneumococcal DNA. The incidence of influenza-associated SARI deaths was estimated at one urban hospital with a defined catchment population. Results We enrolled 1376 patients with influenza-associated SARI and 3% (41 of 1358 with available outcome data) died. In patients with available HIV-status, the case-fatality proportion (CFP) was higher in HIV-infected (5%, 22/419) than HIV-uninfected individuals (2%, 13/620; p = 0.006). CFPs varied by age group, and generally increased with increasing age amongst individuals >5 years (p<0.001). On multivariable analysis, factors associated with death were age-group 45–64 years (odds ratio (OR) 4.0, 95% confidence interval (CI) 1.01–16.3) and ≥65 years (OR 6.5, 95%CI 1.2–34.3) compared to 1–4 year age-group who had the lowest CFP, HIV-infection (OR 2.9, 95%CI 1.1–7.8), underlying medical conditions other than HIV (OR 2.9, 95%CI 1.2–7.3) and pneumococcal co-infection (OR 4.1, 95%CI 1.5–11.2). The estimated incidence of influenza-associated SARI deaths per 100,000 population was highest in children <1 year (20.1, 95%CI 12.1–31.3) and adults aged 45–64 years (10.4, 95%CI 8.4–12.9). Adjusting for age, the rate of death was 20-fold (95%CI 15.0–27.8) higher in HIV-infected individuals than HIV-uninfected individuals. Conclusion Influenza causes substantial mortality in urban South Africa, particularly in infants aged <1 year and HIV-infected individuals. More widespread access to antiretroviral treatment and influenza vaccination may reduce this

    Malnutrition below 5 years remains a global health issue. Severe acute malnutrition (SAM) presents in childhood as oedematous (kwashiorkor) or nonoedematous (marasmic) forms, with unknown long-term cardiovascular consequences. We hypothesized that cardiovascular structure and function would be poorer in SAM survivors than unexposed controls. We studied 116 adult SAM survivors, 54 after marasmus, 62 kwashiorkor, and 45 age/sex/body mass index-matched community controls who had standardized anthropometry, blood pressure, echocardiography, and arterial tonometry performed. Left ventricular indices and outflow tract diameter, carotid parameters, and pulse wave velocity were measured, with systemic vascular resistance calculated. All were expressed as SD scores. Mean (SD) age was 28.8±7.8 years (55% men). Adjusting for age, sex, height, and weight, SAM survivors had mean (SE) reductions for left ventricular outflow tract diameter of 0.67 (0.16; P<0.001), stroke volume 0.44 (0.17; P=0.009), cardiac output 0.5 (0.16; P=0.001), and pulse wave velocity 0.32 (0.15; P=0.03) compared with controls but higher diastolic blood pressures (by 4.3; 1.2-7.3 mm Hg; P=0.007). Systemic vascular resistance was higher in marasmus and kwashiorkor survivors (30.2 [1.2] and 30.8 [1.1], respectively) than controls 25.3 (0.8), overall difference 5.5 (95% confidence interval, 2.8-8.4 mm Hg min/L; P<0.0001). No evidence of large vessel or cardiac remodeling was found, except closer relationships between these indices in former marasmic survivors. Other parameters did not differ between SAM survivor groups. We conclude that adult SAM survivors had smaller outflow tracts and cardiac output when compared with controls, yet markedly elevated peripheral resistance. Malnutrition survivors are thus likely to develop excess hypertension in later life, especially when exposed to obesity. PMID:24980666

    AIM: To investigate the potential protective effect of exogenous recombinant interleukin-22 (rIL-22) on L-arginine-induced acute severe pancreatitis (SAP)-associated lung injury and the possible signaling pathway involved. METHODS: Balb/c mice were injected intraperitoneally with L-arginine to induce SAP. Recombinant mouse IL-22 was then administered subcutaneously to mice. Serum amylase levels and myeloperoxidase (MPO) activity in the lung tissue were measured after the L-arginine administration. Histopathology of the pancreas and lung was evaluated by hematoxylin and eosin (HE) staining. Expression of B cell lymphoma/leukemia-2 (Bcl-2), Bcl-xL and IL-22RA1 mRNAs in the lung tissue was detected by real-time PCR. Expression and phosphorylation of STAT3 were analyzed by Western blot. RESULTS: Serum amylase levels and MPO activity in the lung tissue in the SAP group were significantly higher than those in the normal control group (P < 0.05). In addition, the animals in the SAP group showed significant pancreatic and lung injuries. The expression of Bcl-2 and Bcl-xL mRNAs in the SAP group was decreased markedly, while the IL-22RA1 mRNA expression was increased significantly relative to the normal control group (P < 0.05). Pretreatment with PBS did not significantly affect the serum amylase levels, MPO activity or expression of Bcl-2, Bcl-xL or IL-22RA1 mRNA (P > 0.05). Moreover, no significant differences in the degrees of pancreatic and lung injuries were observed between the PBS and SAP groups. However, the serum amylase levels and lung tissue MPO activity in the rIL-22 group were significantly lower than those in the SAP group (P < 0.05), and the injuries in the pancreas and lung were also improved. Compared with the PBS group, rIL-22 stimulated the expression of Bcl-2, Bcl-xL and IL-22RA1 mRNAs in the lung (P < 0.05). In addition, the ratio of p-STAT3 to STAT3 protein in the rIL-22 group was significantly higher than that in the PBS group (P < 0.05). CONCLUSION

    Tension headache (TH) is an ill-defined headache syndrome, characterized by bilateral, daily headaches with fronto-occipital localisation. TH is often accompanied by a migraine and an abuse of analgesics and/or ergotamine. In the etiology of TH vascular, muscular and psychogenic factors are assumed. Floating transitions to common migraine are discussed. The increased muscle tension is not specific for TH, but more probably a consequence of TH. In addition a decrease of the pain threshold with a deficiency of the antinociceptive system is supposed. The efficacy of tricyclic antidepressives in TH is based on potentiation of serotonergic and noradrenergic mechanisms and - besides their analgetic potencies - upon an increase of the pain threshold. TH prophylaxis is indicated if patients suffer from TH more than ten times per month. Medication are tricyclic antidepressives of the amitriptyline-type. Prophylaxis of TH can only be successful if a simultaneous abuse of analgesics and/or ergotamine is discontinued. In addition, EMG-biofeedback, as well as relaxation - and vasoconstriction training might be helpful in specific cases. PMID:3069680

    Migraine has an important genetic component. The prototypic monogenic form of migraine is hemiplegic migraine, a rare subtype of migraine with aura, for which three causative genes have been identified. Studies of transgenic animal models have substantially improved our understanding of the molecular pathophysiology of this monogenic model disease as well as of migraine in general. Beyond this, there are other (rarer) monogenic forms of migraine, e.g., in the context of hereditary mostly vascular syndromes such as CADASIL. By contrast, the common types of migraine with and without aura are genetically complex. With the identification of the first robust genetic risk variants in large genome-wide association studies, our knowledge in this still dynamically expanding field has substantially increased. This review summarizes the current status of migraine genetics, with a special focus on hemiplegic migraine as well as the most recent findings in complex migraine genetics. In addition, the first preliminary findings on the genetics of other types of primary headache disorders (cluster headache, tension-type headache) are briefly reviewed. PMID:25012921

  12. Cardiovascular magnetic resonance by non contrast T1-mapping allows assessment of severity of injury in acute myocardial infarction

    PubMed Central

    2012-01-01

    Background Current cardiovascular magnetic resonance (CMR) methods, such as late gadolinium enhancement (LGE) and oedema imaging (T2W) used to depict myocardial ischemia, have limitations. Novel quantitative T1-mapping techniques have the potential to further characterize the components of ischemic injury. In patients with myocardial infarction (MI) we sought to investigate whether state-of the art pre-contrast T1-mapping (1) detects acute myocardial injury, (2) allows for quantification of the severity of damage when compared to standard techniques such as LGE and T2W, and (3) has the ability to predict long term functional recovery. Methods 3T CMR including T2W, T1-mapping and LGE was performed in 41 patients [of these, 78% were ST elevation MI (STEMI)] with acute MI at 12-48 hour after chest pain onset and at 6 months (6M). Patients with STEMI underwent primary PCI prior to CMR. Assessment of acute regional wall motion abnormalities, acute segmental damaged fraction by T2W and LGE and mean segmental T1 values was performed on matching short axis slices. LGE and improvement in regional wall motion at 6M were also obtained. Results We found that the variability of T1 measurements was significantly lower compared to T2W and that, while the diagnostic performance of acute T1-mapping for detecting myocardial injury was at least as good as that of T2W-CMR in STEMI patients, it was superior to T2W imaging in NSTEMI. There was a significant relationship between the segmental damaged fraction assessed by either by LGE or T2W, and mean segmental T1 values (P < 0.01). The index of salvaged myocardium derived by acute T1-mapping and 6M LGE was not different to the one derived from T2W (P = 0.88). Furthermore, the likelihood of improvement of segmental function at 6M decreased progressively as acute T1 values increased (P < 0.0004). Conclusions In acute MI, pre-contrast T1-mapping allows assessment of the extent of myocardial damage. T1-mapping might become an important

    Bloodletting at Jing points has been used to treat coma in traditional Chinese medicine. Mild induced hypothermia has also been shown to have neuroprotective effects. However, the therapeutic effects of bloodletting at Jing points and mild induced hypothermia alone are limited. Therefore, we investigated whether combined treatment might have clinical effectiveness for the treatment of acute severe traumatic brain injury. Using a rat model of traumatic brain injury, combined treatment substantially alleviated cerebral edema and blood-brain barrier dysfunction. Furthermore, neurological function was ameliorated, and cellular necrosis and the inflammatory response were lessened. These findings suggest that the combined effects of bloodletting at Jing points (20 μL, twice a day, for 2 days) and mild induced hypothermia (6 hours) are better than their individual effects alone. Their combined application may have marked neuroprotective effects in the clinical treatment of acute severe traumatic brain injury. PMID:27482221

    Objectives Several biomarkers for early detection of severe acute pancreatitis (SAP) have been presented. Matrix metalloproteinases (MMP) and their tissue inhibitors (TIMP) are released early in inflammation. We aimed to assess levels of MMP-7, -8, -9 and TIMP-1 in acute pancreatitis (AP) and explore their ability to detect disease severity. Our second aim was to find an association between MMPs, TIMP and creatinine. Methods We collected plasma samples for MMP-7, -8, -9 and TIMP-1 analyses from 176 patients presenting within 96 h from onset of acute pancreatitis (AP) symptoms. We used samples from 32 control subjects as comparison. The revised Atlanta Classification was utilised to assess severity of disease. Receiver operating characteristic curve analysis and Spearman´s Rho-test were utilised for statistical calculations. Results Compared with controls, patients showed higher levels of all studied markers. MMP-8 was higher in moderately severe AP than in mild AP (p = 0.005) and MMP-8, -9 and TIMP-1 were higher in severe than in mild AP (p<0.001, p = 0.005 and p = 0.019). MMP-8 detected SAP with an AUC of 0.939 [95% CI 0.894–0.984], LR+ 9.03 [5.30–15.39]. MMP-8, -9 and TIMP-1 failed to discern moderately severe AP from SAP. MMP-7 was not different between patient groups. MMP-7 and TIMP-1 correlated weakly with creatinine (Rho = 0.221 and 0.243). MMP-8 might be a useful biomarker in early detection of SAP. PMID:27561093

    2013-01-01

    Introduction Severe acute pancreatitis is still a potentially life threatening disease with high mortality. The aim of this study was to evaluate the therapeutic effect of thoracic epidural anaesthesia (TEA) on survival, microcirculation, tissue oxygenation and histopathologic damage in an experimental animal model of severe acute pancreatitis in a prospective animal study. Methods In this study, 34 pigs were randomly assigned into 2 treatment groups. After severe acute pancreatitis was induced by intraductal injection of glycodesoxycholic acid in Group 1 (n = 17) bupivacaine (0.5%; bolus injection 2 ml, continuous infusion 4 ml/h) was applied via TEA. In Group 2 (n = 17) no TEA was applied. During a period of 6 hours after induction, tissue oxygen tension (tpO2) in the pancreas and pancreatic microcirculation was assessed. Thereafter animals were observed for 7 days followed by sacrification and histopathologic examination. Results Survival rate after 7 days was 82% in Group 1 (TEA) versus 29% in Group 2: (Control) (P <0.05). Group 1 (TEA) also showed a significantly superior microcirculation (1,608 ± 374 AU versus 1,121 ± 510 AU; P <0.05) and tissue oxygenation (215 ± 64 mmHg versus 138 ± 90 mmHG; P <0.05) as compared to Group 2 (Control). Consecutively, tissue damage in Group 1 was reduced in the histopathologic scoring (5.5 (3 to 8) versus 8 (5.5 to 10); P <0.05). Conclusions TEA led to improved survival, enhanced microcirculatory perfusion and tissue oxygenation and resulted in less histopathologic tissue-damage in an experimental animal model of severe acute pancreatitis.

    Accidental inhalation of powder is a potential problem for infants. The clinical effects of inhaling powder depend on the powder contents, degree of aspiration, and the child's underlying systemic response. We present a case of accidental inhalation of rice starch powder in a 17-month-old girl, which led to severe acute respiratory distress syndrome responsive to conventional treatment, ultimately requiring venous-venous extracorporeal membrane oxygenation.

    Healthcare provider talk with parents in early acute care following children’s severe traumatic brain injury (TBI) affects parents’ orientations to these locales, but this connection has been minimally studied. This lack of attention to this topic in previous research may reflect providers’ and researchers’ views that these locales are generally neutral or supportive to parents’ subsequent needs. This secondary analysis used data from a larger descriptive phenomenological study (2005 – 2007) with parents of children following moderate to severe TBI recruited from across the United States. Parents of children with severe TBI consistently had strong negative responses to the early acute care talk processes they experienced with providers, while parents of children with moderate TBI did not. Transcript data were independently coded using discourse analysis in the framework of ethnography of speaking. The purpose was to understand the linguistic and paralinguistic talk factors parents used in their meta-communications that could give a preliminary understanding of their cultural expectations for early acute care talk in these settings. Final participants included 27 parents of children with severe TBI from 23 families. We found the human constructed talk factors that parents reacted to were: a) access to the child, which is where information was; b) regular discussions with key personnel; c) updated information that is explained; d) differing expectations for talk in this context; and, e) perceived parental involvement in decisions. We found that the organization and nature of providers’ talk with parents was perceived by parents to positively or negatively shape their early acute care identities in these locales, which influenced how they viewed these locales as places that either supported them and decreased their workload or discounted them and increased their workload for getting what they needed.

    Background Psilocybin is a well-characterized classic hallucinogen (psychedelic) with a long history of religious use by indigenous cultures, and nonmedical use in modern societies. Although psilocybin is structurally related to migraine medications, and case studies suggest that psilocybin may be efficacious in treatment of cluster headache, little is known about the relationship between psilocybin and headache. Methods This double-blind study examined a broad range of psilocybin doses (0, 5, 10, 20, and 30 mg/70 kg) on headache in 18 healthy participants. Results Psilocybin frequently caused headache, the incidence, duration, and severity of which increased in a dose-dependent manner. All headaches had delayed onset, were transient, and lasted no more than a day after psilocybin administration. Conclusions Possible mechanisms for these observations are discussed, and include induction of delayed headache through nitric oxide release. These data suggest that headache is an adverse event to be expected with the nonmedical use of psilocybin-containing mushrooms as well as the administration of psilocybin in human research. Headaches were neither severe nor disabling, and should not present a barrier to future psilocybin research. PMID:22129843

    Background: The objective of this cross-sectional study was to determine the prevalence of migraine headache among depressed Latino adults of Mexican American origin meeting the criteria for bipolar disorder (BPD) or major depressive disorder (MDD) relative to patients in a psychiatric comparison group. Method: In a mental health clinic for the indigent, consecutively and systematically evaluated acutely depressed Latino adults received structured diagnostic psychiatric interviews based on modules extracted from the Structured Clinical Interview for DSM-IV. All were asked as part of routine assessment whether they had headaches “in the last week.” Patients with unilateral, pounding, pulsating headache were classified as having migraine headache. The prevalence of migraine headache among the patients with BPD and MDD was contrasted with that of patients in a psychiatric comparison group composed of patients with disorders other than schizophrenia or schizoaffective disorder. Logistic regression was used to test for associations and control for confounding effects. The data were collected between August 2001 and November 2004. Results: Eighty-seven patients had BPD and 123 had MDD. Bipolar patients were 2.9 times more likely to have migraine headaches than patients with MDD (P < .0001). There was a trend for patients with MDD to have a higher prevalence of migraine than patients in the psychiatric comparison group. Conclusions: Bipolar patients had a high prevalence of migraine headache relative to patients with MDD. This study suggests that migraine is linked to bipolarity. PMID:20098521

    Although resistin was recently found to modulate insulin resistance in preclinical models of type II diabetes and obesity, recent studies also suggested that resistin has proinflammatory properties. We examined whether the human-specific variant of resistin affects neutrophil activation and the severity of LPS-induced acute lung injury. Because human and mouse resistin have distinct patterns of tissue distribution, experiments were performed using humanized resistin mice that exclusively express human resistin (hRTN(+/-)(/-)) but are deficient in mouse resistin. Enhanced production of TNF-α or MIP-2 was found in LPS-treated hRtn(+/-/-) neutrophils compared with control Rtn(-/-/-) neutrophils. Expression of human resistin inhibited the activation of AMP-activated protein kinase, a major sensor and regulator of cellular bioenergetics that also is implicated in inhibiting inflammatory activity of neutrophils and macrophages. In addition to the ability of resistin to sensitize neutrophils to LPS stimulation, human resistin enhanced neutrophil extracellular trap formation. In LPS-induced acute lung injury, humanized resistin mice demonstrated enhanced production of proinflammatory cytokines, more severe pulmonary edema, increased neutrophil extracellular trap formation, and elevated concentration of the alarmins HMGB1 and histone 3 in the lungs. Our results suggest that human resistin may play an important contributory role in enhancing TLR4-induced inflammatory responses, and it may be a target for future therapies aimed at reducing the severity of acute lung injury and other inflammatory situations in which neutrophils play a major role.

    Objective: To evaluate the feasibility, safety, and tolerability of noninvasive vagus nerve stimulation (nVNS) for the prevention of chronic migraine (CM) attacks. Methods: In this first prospective, multicenter, double-blind, sham-controlled pilot study of nVNS in CM prophylaxis, adults with CM (≥15 headache d/mo) entered the baseline phase (1 month) and were subsequently randomized to nVNS or sham treatment (2 months) before receiving open-label nVNS treatment (6 months). The primary endpoints were safety and tolerability. Efficacy endpoints in the intent-to-treat population included change in the number of headache days per 28 days and acute medication use. Results: Fifty-nine participants (mean age, 39.2 years; mean headache frequency, 21.5 d/mo) were enrolled. During the randomized phase, tolerability was similar for nVNS (n = 30) and sham treatment (n = 29). Most adverse events were mild/moderate and transient. Mean changes in the number of headache days were −1.4 (nVNS) and −0.2 (sham) (Δ = 1.2; p = 0.56). Twenty-seven participants completed the open-label phase. For the 15 completers initially assigned to nVNS, the mean change from baseline in headache days after 8 months of treatment was −7.9 (95% confidence interval −11.9 to −3.8; p < 0.01). Conclusions: Therapy with nVNS was well-tolerated with no safety issues. Persistent prophylactic use may reduce the number of headache days in CM; larger sham-controlled studies are needed. ClinicalTrials.gov identifier: NCT01667250. Classification of evidence: This study provides Class II evidence that for patients with CM, nVNS is safe, is well-tolerated, and did not significantly change the number of headache days. This pilot study lacked the precision to exclude important safety issues or benefits of nVNS. PMID:27412146

    Alteplase is the only approved drug for the treatment of acute ischemic stroke, but it is offered to a minority of patients, not only because of the short therapeutic window but also because of the numerous contraindications associated with thrombolysis, such as thrombocytopenia. There is some controversy on the true risk associated with thrombolysis in patients with thrombocytopenia. Here we report the case of a young patient, who developed an in-hospital acute ischemic stroke involving a large territory of the right middle cerebral artery, who was successfully treated with intravenous alteplase, despite having thrombocytopenia and prolonged prothrombin times due to systemic lupus erythematosus and antiphospholipid syndrome. This case exemplifies the need to reassess contraindications for thrombolysis, many based on expert opinion and not clinical evidence, especially in complex clinical situations. PMID:26575492

    Background Adenoviruses are the second most prevalent cause of acute lower respiratory infection of viral origin in children under four years of age in Buenos Aires, Argentina. The purpose of this study was to analyze the clinical features and outcome of acute lower respiratory infection associated with different adenovirus genotypes in children. Methods Twenty-four cases of acute lower respiratory infection and adenovirus diagnosis reported in a pediatric unit during a two-year period were retrospectively reviewed. Adenovirus was detected by antigen detection and isolation in HEp-2 cells. Adenovirus DNA from 17 isolates was studied by restriction enzyme analysis with Bam HI and Sma I. Results Subgenus b was found in 82.3% of the cases, and subgenus c in 17.7%. Within subgenus b, only genotype 7 was detected, with genomic variant 7h in 85.7% (12/14) and genomic variant 7i in 14.3% (2/14). Mean age was 8.8 ±; 6 months, and male to female ratio was 3.8: 1. At admission, pneumonia was observed in 71% of the cases and bronchiolitis in 29%. Malnutrition occurred in 37% of the cases; tachypnea in 79%; chest indrawing in 66%; wheezing in 58%; apneas in 16%; and conjunctivitis in 29%. Blood cultures for bacteria and antigen detection of other respiratory viruses were negative. During hospitalization, fatality rate was 16.7% (4 /24). Of the patients who died, three had Ad 7h and one Ad 7i. Thus, fatality rate for adenovirus type 7 reached 28.6% (4/14). Conclusions These results show the predominance of adenovirus 7 and high lethality associated with the genomic variants 7h and 7i in children hospitalized with acute lower respiratory infection.

    Objectives The primary aim of this study was to determine the prevalence of selected bacterial and viral enteropathogens in children hospitalized with acute gastroenteritis and the secondary aim was to characterize the clinical course and the outcome. Methodology A retrospective audit of children (<15 years) admitted with acute gastroenteritis during January 2008 to October 2010. Stool samples were analyzed for bacterial pathogens and for the Rotavirus. Demographics, clinical presentations, hospital course and outcome were extracted from the admission records. Results There were 571 children hospitalized with acute gastroenteritis, which accounted for 11% of all medical hospitalization in children. Overall, 42.9% of these children were ≤12 months in age. Stool test result was documented in 46.6% of children hospitalized with gastroenteritis and an enteropathogen was isolated in 36.8% of cases with documented stool test result. Non-typhoidal Salmonella species was the most commonly isolated enteropathogen accounting for 21.1% of all the documented cases. Rotavirus was identified as an etiological agent in 9.0%. Of the 56 children who had non-typhoidal salmonella gastroenteritis, 54(96.4%) were younger than 5 years. The median duration of hospitalization was 2 days (Range 1 day to 9 days). There were no deaths. Conclusion Non-typhoidal salmonella was the most common enteropathogen isolated and this was followed by the Rotavirus. PMID:25780359

    Neuromodulation is a promising, novel approach for the treatment of primary headache disorders. Neuromodulation offers a new dimension in the treatment that is both easily reversible and tends to be very well tolerated. The autonomic nervous system is a logical target given the neurobiology of common primary headache disorders, such as migraine and the trigeminal autonomic cephalalgias (TACs). This article will review new encouraging results of studies from the most recent literature on neuromodulation as acute and preventive treatment in primary headache disorders, and cover some possible underlying mechanisms. We will especially focus on vagus nerve stimulation (VNS) and sphenopalatine ganglion (SPG) since they have targeted autonomic pathways that are cranial and can modulate relevant pathophysiological mechanisms. The initial data suggests these approaches will find an important role in headache disorder management going forward. PMID:27278441

    Testicular (germ cell) cancer is a model of a chemocurable malignancy and tends to have a favourable prognosis even in advanced stages due to exquisite sensitivity to platinum-based chemotherapy. However, both acute and longer-term toxicities of multiagent chemotherapy remain significant as causes of morbidity, very occasionally mortality, and impaired quality-of-life. Here, we report a case of acute cerebral venous sinus thrombosis occurring within 10 days of chemotherapy initiation in a young patient without comorbidities, whose only predisposing factors were malignancy, chemotherapy, and perhaps mild dehydration. The clinical presentation was also unusual with headache of moderate severity only without focal or global neurologic deficits. We suspect that cisplatin may have had direct vasculotoxic effects. The patient recovered fully after short-duration anticoagulation but oncologists must remain aware of unusual and unpredictable complications of cytotoxic treatment. PMID:27200199

    The Internet is capable of providing an unprecedented amount of information to both physicians and patients interested in headache. To assess the status of headache information on the Internet (as of January 2000), a search for 'headache' was performed using 10 leading Internet search engines. The number of web pages identified ranged from 4419 (WebCrawler) to 506 426 (Northern Light). The 'average' search yielded nearly 150 000 web page listings for 'headache'. The content was then reviewed of the top 10 listed web pages for each search (i.e. a total of 100 page listings). The results demonstrate that, at the present time, Internet-based information on headache is extensive but poorly organized. Editorial review of this potential valuable resource is required in order to maximize its utility in headache education and management. PMID:11298659

    Background The mechanism of veisalgia cephalgia or hangover headache is unknown. Despite a lack of mechanistic studies, there are a number of theories positing congeners, dehydration, or the ethanol metabolite acetaldehyde as causes of hangover headache. Methods We used a chronic headache model to examine how pure ethanol produces increased sensitivity for nociceptive behaviors in normally hydrated rats. Results Ethanol initially decreased sensitivity to mechanical stimuli on the face (analgesia), followed 4 to 6 hours later by inflammatory pain. Inhibiting alcohol dehydrogenase extended the analgesia whereas inhibiting aldehyde dehydrogenase decreased analgesia. Neither treatment had nociceptive effects. Direct administration of acetate increased nociceptive behaviors suggesting that acetate, not acetaldehyde, accumulation results in hangover-like hypersensitivity in our model. Since adenosine accumulation is a result of acetate formation, we administered an adenosine antagonist that blocked hypersensitivity. Discussion Our study shows that acetate contributes to hangover headache. These findings provide insight into the mechanism of hangover headache and the mechanism of headache induction.

    Background: Delay in diagnosis and treatment of acute appendicitis (AA) results in an increased rate of perforation, postoperative morbidity, mortality and hospital length of stay. Several biochemical parameters including white blood cell (WBC) count, C-reactive protein (CRP), interleukin-6 (IL6) and Procalcitonin (PCT) have been used to further improve the clinical diagnosis of AA. The aim of this study was to assess the value of procalcitonin as a predictor of diagnosis and severity of appendicitis in order to improve the clinical decision making, since other studies have been unable to demonstrate a diagnostic value for PCT elevation in acute appendicitis. Methods: One-hundred patients who underwent open appendectomy, including 75 men and 25 women with a mean age of 28 years were included in this study. Procalcitonin values were measured by an immunofluorescent method). Serum PCT>0.5 ng/ml was considered positive. The PCT serum values were measured in four different categories, including ˂0.5ng/ml, 0.5-2 ng/ml, 2-10ng/ml and more than 10ng/ml. Results: The sensitivity and specificity of PCT level measurement for acute appendicitis diagnosis were 44% and 100% respectively. The value of PCT increased with the severity of appendicitis and also with the presence of peritonitis and infection, at the site of surgery. Conclusions: Procalcitonin measurement cannot be used as a diagnostic test for adult patients with acute appendicitis and its routine use in such patients is not cost effective and conclusive. Procalcitonin values can be used as a prognostic marker and predictor of infectious complications following surgery and it can help to carry out timely surgical intervention which is highly recommended in patients with PCT values more than 0.5ng/ml.

    Recent studies have improved our knowledge of the mechanisms underlying orofacial pain. This review presents the most relevant aspects of such mechanisms according to the different clinical features of the various entities in orofacial pain: odontogenic pain, atypical facial pain and other idiopathic orofacial pain conditions and musculoskeletal pain characterized by pain in the temporomandibular joint and/or the associated muscles of mastication. The link between the muscular temporomandibular disorders and tension type headache is particularly considered in the light of the different possible mechanisms. PMID:16141969

    The starting point for German headache research and clinical education was the engagement of D. Soyka in the 1970s, which enabled the foundation of the German Headache Society (DMKG) on 28 June 1979 and, some years later, the founding congress of the International Headache Society (IHS) in Munich 1982. As a result of these activities, in 1988 the first international classification of headache disorders was published. This classification was one of the major milestones in the development of basic as well as clinical headache research. In the following years, epidemiological studies all over the world showed a 1-year prevalence for headache of approximately 60%, making headaches one of the most frequent medical complaints. Basic research showed an involvement of serotonergic mechanisms in migraine pain and triptans were one of the first drugs designed to influence these mechanisms. Functional brain imaging studies in migraine patients further showed a cyclic modulation of the activity of brainstem areas independent of the current pain state. Various research groups were involved in the clarification of the role of calcitonin gene-related peptide (CGRP) in migraine and cluster headache. A specific development in the German headache scene is the establishment of integrated headache centers and reflects the primarily multimodal treatment approach in Germany which contrasts with the settings in other countries. These successful developments are increasingly being undermined by the fact that the low financial support of headache research, for example, by the German science council is causing a decreasing interest in headache research, with the consequence that the clinical education of students as well as young medical doctors shows increasing deficits. The consequence for the future will be a deficit in the clinical care of the population. PMID:26264901

    Objective: The risk of stroke in patients with recently symptomatic carotid stenosis is considerably higher than in patients with asymptomatic stenosis. In the present study it was hypothesised that excessive platelet activation might partly contribute to this difference. Methods: A full blood count was done and whole blood flow cytometry used to measure platelet surface expression of CD62P, CD63, and PAC1 binding and the percentage of leucocyte–platelet complexes in patients with acute (0–21 days, n = 19) and convalescent (79–365 days) symptomatic (n = 16) and asymptomatic (n = 16) severe (⩾70%) carotid stenosis. Most patients were treated with aspirin (37.5–300 mg daily) although alternative antithrombotic regimens were more commonly used in the symptomatic group. Results: The mean platelet count was higher in patients with acute and convalescent symptomatic compared with asymptomatic carotid stenosis. There were no significant differences in the median percentage expression of CD62P and CD63, or PAC1 binding between the acute or convalescent symptomatic and asymptomatic patients. The median percentages of neutrophil–platelet (p = 0.004), monocyte–platelet (p = 0.046), and lymphocyte–platelet complexes (p = 0.02) were higher in acute symptomatic than in asymptomatic patients. In patients on aspirin monotherapy, the percentages of neutrophil–platelet and monocyte–platelet complexes (p = 0.03) were higher in acute symptomatic (n = 11) than asymptomatic patients (n = 14). In the convalescent phase, the median percentages of all leucocyte–platelet complexes in the symptomatic group dropped to levels similar to those found in the asymptomatic group. Conclusion: Increased platelet count and leucocyte–platelet complex formation may contribute to the early excess risk of stroke in patients with recently symptomatic carotid stenosis. PMID:16107361

    The treatment of acute chest pain can be a challenge in palliative care. Firstly, because acute chest pain is a symptom of a paucity of diseases, which makes diagnosis difficult and time consuming, while there is also a time constraint, due to the extreme suffering of the patient. Secondly, the condition of a patient with advanced cancer disease and co-morbidities does not always allow for required diagnostic procedures. The present report describes a case of acute, severe epigastric/chest pain in a patient with dynamic disease progression, who was receiving palliative care. This study also demonstrates that the pathophysiology of pain in a terminal patient may determine the treatment strategy. The patient in the present case was a 41-year-old male, who had previously undergone gastrectomy for stomach cancer, followed by postoperative chemotherapy. The patient was treated with palliative chemotherapy for metastases to the lungs, liver and lymph nodes, which led to the development of iatrogenic peripheral neuropathy. The patient was subsequently admitted to the Palliative Medicine In-patient Unit of the University Hospital of Lord’s Transfiguration (Poznan, Poland) with the complaint of acute epigastric and chest pain. An electrocardiogram, echocardiogram, chest and abdomen computerized tomography scan, esophagoduodenoscopy and laboratory analyses were performed to determine the source of the pain. The patient was treated with morphine sulfate, metoclopramide, midazolam, diazepam, acetaminophen, ketamine, hyoscine butylbromide, propofol, dexamethasone and amoxycillin, and received parenteral nutrition. As the source of pain remained unclear, a second esophagoduodenoscopy was performed to determine a diagnosis, resulting in pain relief. Thus, in the present case, esophagoduodenoscopy was diagnostic and therapeutic. Furthermore, although the treatment of acute chest pain may be a challenge in palliative care, the present study indicates that pain treatment should be

    Congenital methemoglobinemia is a rare condition resulting from a deficiency of nicotinamide adenine dinucleotide-cytochrome b5 reductase. Acquired methemoglobinemia may result due to certain drugs, chemicals and food items. Information on epidemiological determinants from India is sparse. This report describes methemoglobinemia in a 4-year-old child after parenteral administration of quinine causing acute kidney injury. This case emphasizes the need of awareness of potential adverse events of antimalarial drugs. Prompt management of methemoglobinemia is essential to avoid potential life-threatening complications.

    Acute respiratory distress syndrome (ARDS) is a life threatening complication of H1N1 pneumonia. According to the Berlin conference guidelines, severe ARDS requires management with early invasive mechanical ventilation. Whether noninvasive positive pressure ventilation (NIPPV) should be attempted in patients with H1N1 pneumonia is still a matter of debate. We report the case of one patient with severe ARDS without other organ failure. The patient was managed successfully using NIPPV. Endotracheal intubation was avoided and the patient was discharged from the intensive care unit (ICU) after 10 days with a successful outcome. NIPPV can be useful in patients with isolated severe H1N1 ARDS provided early improvement of the oxygenation parameters is achieved. Patients with multiple organ failure or with persistent severe hypoxemia under noninvasive ventilation should be electively intubated and started on invasive mechanical ventilation. PMID:27275488
