Patients with the Marfan syndrome are considered to be high risk during pregnancy and warrant a complete multidisciplinary evaluation. One goal is to minimize hemodynamic fluctuations during labor since hypertensive episodes may result in aortic dissection or rupture. Although they may prevent these complications, neuraxial techniques may be complicated by dural ectasia. The case of a parturient with the Marfan syndrome and mild dural ectasia is presented. During attempted labor epidural placement, unintentional dural puncture occurred. A spinal catheter was used for adequate labor analgesia, and a resultant postdural puncture headache was alleviated by an epidural blood patch under fluoroscopic guidance. PMID:27695168

Headache is a potential complication of epidural injection. We report a patient who developed headache 5 days after a lumbar epidural steroid injection, which was not related to the epidural procedure, but caused by Duloxetine induced hyponatremia. Antidepressant drug induced headache should be considered in the differential diagnosis of post dural puncture headache.

Postpartum headache can be due to many causes. In a patient with previous epidural analgesia, the headache can be attributed to post-dural puncture headache, even if the symptoms are not typical of this clinical entity. We report a case of a post-partum with accidental dural tap during the insertion of an epidural catheter for labour analgesia, and who referred to headaches in the third post-partum day. Initially, a post-dural puncture headache was suspected, but the subsequent onset of seizures and visual impairment meant that the diagnosis had to be reconsidered. In this case report, the clinical and pathophysiological features of posterior reversible encephalopathy syndrome and reversible cerebral vasoconstriction syndrome, as well as the differential diagnosis of post-partum headaches are described.

The incidence of postdural puncture headache, its severity, time of onset and duration following spinal anaesthesia in female subjects using 25 gauge Quincke needles are discussed in this paper. Postdural puncture headache was seen in only 3% of the cases. The headache appeared mainly on the 1st postoperative day and was associated with nausea and vomiting in one case; and it disappeared by the 2nd to 3rd day following administration of mild analgesics and anti-emetics.

Stress is commonly reported to contribute to migraine although mechanisms by which this may occur are not fully known. The purpose of these studies was to examine whether norepinephrine (NE), the primary sympathetic efferent transmitter, acts on processes in the meninges that may contribute to the pain of migraine. NE was applied to rat dura using a behavioral model of headache. Primary cultures of rat trigeminal ganglia retrogradely labeled from the dura mater and of rat dural fibroblasts were prepared. Patch-clamp electrophysiology, Western blot, and ELISA were performed to examine the effects of NE. Conditioned media from NE-treated fibroblast cultures was applied to the dura using the behavioral headache model. Dural injection both of NE and media from NE-stimulated fibroblasts caused cutaneous facial and hindpaw allodynia in awake rats. NE application to cultured dural afferents increased action potential firing in response to current injections. Application of NE to dural fibroblasts increased phosphorylation of ERK and caused the release of interleukin-6 (IL-6). These data demonstrate that NE can contribute to pro-nociceptive signaling from the meninges via actions on dural afferents and dural fibroblasts. Together, these actions of NE may contribute to the headache phase of migraine. © International Headache Society 2015.

The dural and arachnoid hole caused by lumbar puncture needles is a determining factor in triggering headaches. The aim of this study is to assess the dimensions and morphological features of the dura mater and arachnoids when they are punctured by a 22 gauge Quincke needle having its bevel either in the parallel or in the transverse position. Fifty punctures were made with 22 gauge Quincke needles in the dural sac of four fresh cadavers using an "in vitro" model especially designed for this purpose. The punctures were performed by needles with bevels parallel or perpendicular to the spinal axis and studied under scanning electron microscopy. Thirty five of the 50 punctures done by Quincke needles (19 in the external surface and 16 in the internal) were used for evaluation. When the needle was inserted with its bevel parallel to the axis of the dural sac (17 of 35), the size of the dura-arachnoid lesion was 0.032 mm(2) in the epidural surface and 0.037 mm(2) in the subarachnoid surface of the dural sac. When the needle's bevel was perpendicular to the axis (18 of 35) the measurement of the lesion size was 0.042 mm(2) for the external surface and 0.033 mm(2) for the internal. There were no statistical significant differences between these results. It is believed that the reported lower frequency of postdural puncture headache when the needle is inserted parallel to the cord axis should be explained by some other factors besides the size of the dura-arachnoid injury.

Activation of transient receptor potential ankyrin-1 (TRPA1) on meningeal nerve endings has been suggested to contribute to environmental irritant-induced headache but this channel may also contribute to other forms of headache such as migraine. The preclinical studies described here examined functional expression of TRPA1 on dural afferents and investigated whether activation of TRPA1 contributes to headache-like behaviors. Whole-cell patch-clamp recordings were performed in vitro using two TRPA1 agonists, mustard oil (MO) and the environmental irritant umbellulone (UMB), on dural-projecting trigeminal ganglion neurons. Application of MO and UMB to dural afferents produced TRPA1-like currents in approximately 42% and 38% of cells, respectively. Using an established in vivo behavioral model of migraine-related allodynia, dural application of MO and UMB produced robust time-related tactile facial and hindpaw allodynia that was attenuated by pretreatment with the TRPA1 antagonist HC-030031. Additionally, MO or UMB were applied to the dura and exploratory activity was monitored for 30 minutes using an automated open-field activity chamber. Dural MO and UMB decreased the number of vertical rearing episodes and the time spent rearing in comparison to vehicle treated animals. This change in activity was prevented in rats pretreated with HC-030031 as well as sumatriptan, a clinically effective anti-migraine agent. These data indicate that TRPA1 is expressed on a substantial fraction of dural afferents and activation of meningeal TRPA1 produces behaviors consistent with those seen in patients during migraine attacks. Further, they suggest that activation of meningeal TRPA1 via endogenous or exogenous mechanisms can lead to afferent signaling and headache. PMID:22809691

Electron Microscopy of Dural and Arachnoid Disruptions After Subarachnoid Block.

PubMed

It has been customary to attribute postdural puncture headache (PDPH) incidence and severity to size and nature of the dural hole produced during major neuraxial blockade or diagnostic dural puncture. Needle orientation in relation to the direction of dural fibers was thought to be of importance because of the propensity for horizontal bevel placement to cause cutting rather than splitting of the dural fibers. In vitro punctures of stringently quality-controlled human dural sac specimens were obtained with 27-gauge (27G) Whitacre needle (n = 33), with 29G Quincke used parallel to the spinal axis (n = 30), and with 29G Quincke in perpendicular approach (n = 40). The samples were studied with a scanning electron microscope, and the perimeter, appearance, and area (%) of the lesion were calculated. When using small 27G to 29G needles, neither needle tip characteristics nor needle orientation had a substantial bearing on the damage to dural fibers in the dural lesion. Of ultimate importance was the characteristic and size of the hole in the arachnoid. Arachnoid layer lesions produced by different types of spinal needles were not markedly different. Accepted theories of the etiology of PDPH need to be revised. This article marks the first time that arachnoid layer damage has been quantified. Dural fibers tend to have sufficient "memory" to close back the hole created by a spinal needle, whereas arachnoid has diminished capacity to do so. The pathogenesis of PDPH and its resolution algorithm are a far more complex process that involves many more "stages" of development than hitherto imagined.

To compare the frequency and severity of post dural puncture headache in obstetric patients using 25G Quincke, 27G Quincke and 27G Whitacre spinal needles. Comparative, randomized, double-blind, interventional study. Liaquat University Hospital Hyderabad from October 2005 to December 2006. 480 ASA I-II full term pregnant women, 18 to 45 years of age, scheduled for elective Caesarean section, under spinal anaesthesia, were randomized into three groups: Group I (25G Quincke spinal needle: n=168), Group II (27G Quincke spinal needle: n=160) and Group III (27G Whitacre spinal needle: n=152). Spinal anaesthesia was performed with 1.5-2.0 ml 0.75% hyperbaric bupivacaine using 25G Quincke spinal needle (Group I), 27G Quincke spinal needle (Group II) and 27G Whitacre spinal needle (Group III) at L3-4 inter-vertebral space. Each patient was assessed daily for four consecutive days following Caesarean section. Frequency and severity and of postdural puncture headache (PDPH) were recorded. Data were analyzed using SPSS-11. Frequency of PDPH following the use of 25G Quincke (Group I), 27G Quincke (Group II) and 27G Whitacre (Group III) spinal needles was 8.3% (14/168), 3.8% (6/160) and 2.0% (3/152) respectively. In Group I, PDPH was mild in 5 patients, moderate in 7 patients and severe in 2 patients. In Group II, it was mild in 2, moderate in 3 and severe in 1 patient. In group III, it was mild in 2 and moderate in 1 patient. Severe PDPH did not occur in Group III. Most of the patients with PDPH developed it on 1st and 2nd postoperative day. When using a 27G Whitacre spinal needle, the frequency and severity of PDPH was significantly lower than when a 25G Quincke or 27G Quincke needle was used.

a gap in the caudal third of the ligamentum flavum was more frequent than in the middle or cephalic portion of the ligamentum flavum. Among the 4,396 epidural injections performed at C7-T1, C6-C7, and C5-C6, 1,227 were performed at C7-T1; 1,835 were performed at C6-C7; and 1,334 were performed at C5-C6. Dural punctures were observed in 1.8% (24 procedures) at the C5-C6 level entry; 0.87% (16 procedures) at the C6-C7 level entry; and 1.71% (21 procedures) at the C7-T1 level. There was no significant difference among the entry levels. No complications or spinal cord damage or postdural puncture headache were observed. The limitations of this report include that it is an assessment by only 2 well experienced physicians, even though it included a relatively large number of patients. This study illustrates that dural puncture is equally prevalent, though very rare, irrespective of the needle entry level into the epidural space, with an overall dural puncture rate of 1.4%, with 1.8% at the C5-C6 level, 0.87% at the C6-C7 level, and 1.71% at the C7-T1 level. Based on the present literature, it appears that performing the procedure by inserting the needle into the cephalic portion of the intervertebral space rather than the caudal portion may be safer.

Episodic Dural Stimulation in Awake Rats: A Model for Recurrent Headache

Objectives To model, in rats, the development of chronic trigeminal nociceptive hypersensitivity seen in patients with recurrent headache. Background Pathophysiology studies suggest that patients with recurrent migraine headache experience repeated bouts of dural nociceptor activation. In some patients, the severity and frequency of headache attacks increase over time. Patients with recurrent headache are hypersensitive to nitric oxide donors, such as glyceryl trinitrate (GTN). Current trigeminal pain models do not reflect the repeated episodic nature of dural nociceptor activation in patients with recurrent headache. Repeated nociceptor activation creates long-lasting changes in the periphery and brain due to activity-dependent neuronal plasticity. An animal model of repeated activation of dural nociceptors will facilitate the study of the physiological changes caused by repeated, episodic pain and the factors important for the transition of episodic to chronic migraine. Methods We induced dural inflammation by infusing an inflammatory soup (IS) through a cannula on the dura in awake behaving rats. This was repeated 3 times per week for up to 4 weeks. Periorbital pressure sensory testing was used to monitor the change in trigeminal sensitivity. Rats were challenged with GTN to test the hypothesis that many dural stimulations are required to model the hypersensitivity of migraine patients. Quantitative trigeminal sensory testing and microdialysis in the trigeminal nucleus caudalis (TNC) were used to measure GTN hypersensitivity. Results Multiple infusions of IS (>8), over weeks, induced a long-lasting decrease in periorbital pressure thresholds that lasted >3 weeks after the last infusion. In contrast, IS infusion in IS-naive rats and those that received 3 IS infusions produced only short-lasting decreases in periorbital pressure thresholds. Rats that received more than 8 IS infusions showed a marked increase in their neurochemical and behavioral responses to GTN

Spinal saddle block represents nearly the ideal anaesthesia technique for anorectal surgery. Post-dural puncture headache (PDPH) is a dreaded complication but can be decreased by the use of non-cutting spinal needles to rates less than 1%. Though, cutting Quincke type needles are still widely used for economic reasons, leading to a higher rate of PDPH. We performed this study to demonstrate a reduction of PDPH by the use of very small 29-G compared with commonly used 25-G Quincke type spinal needles. Two hundred sixteen adult patients (male/female, 19-83 years, ASA status I-III) were randomised 1:1 to groups, in which either a 25-G or a 29-G Quincke type spinal needle was used for a spinal saddle block. The incidence of PDPH was assessed during 1 week after surgery. Thirty-nine of 216 patients developed PDPH but there was no difference between the two needle sizes (25-G, n = 18/106 vs. 29-G, n = 21/110, p = 0.6870). Women suffered significantly more from PDPH than men (23/86 vs. 16/130, p = 0.0069). Ambulatory patients had a later onset of PDPH than in-patients (24 h [0.5-72] vs. 2 h [0.2-96], p = 0.0002) and the headache was more severe in these patients (NRS 7 [2-10] vs. NRS 3 [1-8], p = 0.0009). The use of 29-G compared with 25-G Quincke needles led to no reduction of PDPH and is considerably higher compared with data from pencil-point needles. The use of non-cutting or pencil-point spinal needles should become the standard for performing spinal saddle block.

Caudal blocks are performed through the sacral hiatus in order to provide pain control in children undergoing lower abdominal surgery. During the block, it is important to avoid advancing the needle beyond the sacrococcygeal ligament too much to prevent unintended dural puncture. This study used demographic data to establish simple guidelines for predicting a safe needle depth in the caudal epidural space in children. A total of 141 children under 12 years old who had undergone lumbar-sacral magnetic resonance imaging were included. The T2 sagittal image that provided the best view of the sacrococcygeal membrane and the dural sac was chosen. We used Picture Achieving and Communication System (Centricity ® PACS, GE Healthcare Co.) to measure the distance between the sacrococcygeal ligament and the dural sac, the length of the sacrococcygeal ligament, and the maximum depth of the caudal space. There were strong correlations between age, weight, height, and BSA, and the distance between the sacrococcygeal ligament and dural sac, as well as the length of the sacrococcygeal ligament. Based on these findings, a simple formula to calculate the distance between the sacrococcygeal ligament and dural sac was developed: 25 × BSA (mm). This simple formula can accurately calculate the safe depth of the caudal epidural space to prevent unintended dural puncture during caudal block in children. However, further clinical studies based on this formula are needed to substantiate its utility. © 2017 John Wiley & Sons Ltd.

The aim of this meta-analysis was to evaluate the postdural puncture headache after spinal anesthesia with Whitacre spinal needles compared with Quincke spine needles. We searched several databases, including PubMed, Embase, ISI Web of Knowledge, and Cochrane Central Register of Controlled Trials until October 10th, 2014, for randomized controlled trials that compared spinal anesthesia with Whitacre spinal needles or Quincke spine needles for postdural puncture headache. Two reviewers independently screened the literature, assessed the risk for bias and extracted data. We used RevMan 5.3 software to perform the meta-analysis. Studies were included for the main end points if they addressed the following: frequency of postdural puncture headache, severity of postdural puncture headache as assessed by limitation of activities, and frequency of epidural blood patch. Nine randomized controlled trials were included for meta-analysis. The meta-analysis showed that spinal anesthesia with Whitacre spinal needles achieved lower incidence of postdural puncture headache(RR 0.34; 95% CI [0.22, 0.52]; P < .00001); in addition, the severity of postdural puncture headache was lower in the Whitacre spinal needle group (RR 0.32; 95% CI [0.16, 0.66]; P = .002). Furthermore, the frequency of an epidural blood patch in the Whitacre spinal needle group was lower compared with that in the Quincke spine needle group (RR 0.15; 95% CI [0.04, 0.51]; P = .002). We suggest the Whitacre spinal needles as a superior choice for spinal anesthesia compared with Quincke spine needles. © 2016 American Headache Society.

A 28-year-old woman presented with a severe unremitting frontal postural headache associated with photophobia. This started immediately after standing following reaching orgasm during sexual intercourse. Fifty-two days previously, the patient underwent bilateral L4-L5 decompression laminotomies and a left L4-L5 discectomy for excision of a large herniated intervertebral disc. Subarachnoid haemorrhage was excluded with a CT scan. Brain and lumbar MRI showed enhancement of the pachymeninges and a cerebrospinal fluid (CSF) leak into the deep soft tissue planes. Conservative treatment for 5 days failed to alleviate the patient's symptoms. An exploration and repair of a dural tear was performed. Subsequently, the headache subsided but the patient developed a low-grade infection requiring 12 weeks of antibiotics. Six months later the patient was asymptomatic. This is the first case report of a delayed presentation of a dural tear occurring during sexual intercourse following lumbar surgery. 2014 BMJ Publishing Group Ltd.

A randomised study was performed to compare the frequency of postdural puncture headache in 56 patients who underwent spinal anaesthesia for extra-corporeal shockwave lithotripsy using either a Sprotte 24 G (n = 28) or Vygon 29 G or Quincke type needle (n = 28). Frequency of headache was recorded in a similar group of 28 patients who received general anaesthesia. Dural puncture was easier with the Sprotte 24 G cannula than with the less stable Quincke needle, as documented by a significantly shortened time for insertion of the cannula (4.6 +/- 2.6 vs 8.6 +/- 6.3 min, P less than 0.005). The total frequency of post-operative headache was 57% in the Vygon 29 G group and 25% in the Sprotte 24 G group; 21% of patients in the general anaesthesia group complained of headache. Frequency of postdural puncture headache, classified as being posture-related, was 25% in the 29 G Vygon group, compared with 11% in the 24 G Sprotte group (P = 0.148). When only moderate and severe postdural puncture headache was considered, there was a significant difference (25% vs. 4%; P = 0.026) in favour of the Sprotte cannula. Thus, the 24 G Sprotte needle was at least as effective as the 29 G Vygon needle, and there is a suggestion that the former is more effective in minimising the incidence of moderate or severe postdural puncture headache.

The postdural puncture headache (PDPH) and postdural puncture backache (PDPB) are well-known complications of spinal anesthesia. There are some attempts to reduce the frequency of complication such as different design of the spinal needles. The primary outcome of this study is to compare the incidence of PDPH between 26-gauge Atraucan and 26-gauge Quincke spinal needles in elective cesarean operations. The severity of symptoms, the incidence of backache, technical issues, and comparison of cost of needles are secondary outcomes. After Investigational Review Board approval, a randomized, prospective, double-blinded study was designed in 682 American Society of Anesthesiologists I-II women having elective cesarean operations under spinal anesthesia. Patients were divided into two groups as 26-gauge Atraucan Group A ( n = 323) and 26-gauge Quincke spinal needles Group Q ( n = 342). All patients were questioned about backache 1 week later. Differences between categorical variables were evaluated with Chi-square test. Continuous variables were compared by Student's t -test for two independent groups. A two-sided P < 0.05 was considered statistically significant for all analyses. There were no significant differences between groups in all demographic data. The one attempt success rate of the dural puncture in Group A (70,58%) and in Group Q (69.3%) was similar ( P > 0.05). The incidence of PDPH was 6.5% in Group A and 4.9% in Group Q ( P > 0.05). The epidural blood patch was performed to the three patients in Group A and five patients in Group Q who had severe headache ( P > 0.05). The incidence of PDPB was 4.33% versus 2.04% in Group A and Group Q ( P > 0.05). The incidence of complication rates and technical handling characteristics did not differ between two groups. Quincke needle is cheaper than Atracaun needle, so it can be a cost-effective choice in obstetric patients.

The study was designed to evaluate the influence of needle size and design on the rate of leakage following dural puncture. An in vitro model and fresh human lumbar dura were used to examine the rate of fluid leakage after puncture with Sprotte (24-gauge and 26-gauge), Atraucan (24-gauge and 26-gauge), Quincke (26-gauge and 29-gauge), and Whitacre (22-gauge and 25-gauge) needles. The study confirmed that finer-gauge needles tend to produce less leakage and that traditional Quincke pattern bevels result in greater leakage than pencil-point designs of the same diameter. The comparably low leakage rate produced by the Atraucan, a new needle with a terminal opening, suggests that this needle is worthy of further clinical evaluation.

To compare the frequency of postdural puncture headache (PDPH) and failure rate of spinal anesthesia using 25-gauge Quincke and 25-gauge Whitacre needles in obstetric patients. Single blinded, interventional experimental study. This study was conducted at the Department of Anesthesiology, Pain Management and Surgical Intensive Care Unit, Dow University of Health Sciences and Civil Hospital, Karachi from November 1, 2003-April 15, 2004. One hundred females, aged 18-35 years, ASA physical status I and II, with singleton pregnancy undergoing elective or emergency cesarean section under spinal anesthesia were randomly allocated to receive spinal anesthesia either by using 25-gauge Quincke or 25-gauge Whitacre needles. Patients were followed for 3 days postoperatively. Headache, its relation with posture, onset, duration, severity and response to the treatment were recorded. Compared with the Whitacre group, frequency of postdural puncture headache was significantly higher in Quincke group (*p=0.015), while the overall occurrence of non-postdural puncture headache (NPDPH) did not differ significantly between two groups (p=0.736). Most of PDPH developed on 2nd postoperative day, were mild in nature and resolved within 48 hours of their onset. There was no significant difference in the failure rate of spinal anesthesia in both groups (p=0.149). It is suggested that use of 25-gauge Whitacre needle reduces the frequency of PDPH without increasing the failure rate of spinal anesthesia in obstetric patients.

A two-sided P < 0.05 was considered statistically significant for all analyses. Results: There were no significant differences between groups in all demographic data. The one attempt success rate of the dural puncture in Group A (70,58%) and in Group Q (69.3%) was similar (P > 0.05). The incidence of PDPH was 6.5% in Group A and 4.9% in Group Q (P > 0.05). The epidural blood patch was performed to the three patients in Group A and five patients in Group Q who had severe headache (P > 0.05). The incidence of PDPB was 4.33% versus 2.04% in Group A and Group Q (P > 0.05). Conclusions: The incidence of complication rates and technical handling characteristics did not differ between two groups. Quincke needle is cheaper than Atracaun needle, so it can be a cost-effective choice in obstetric patients. PMID:28663641

Influence of sex, estrous cycle and estrogen on intracranial dural mast cells

Background The frequency of migraine headaches is higher in women than in men and in susceptible women attacks are related to changes in ovarian hormone levels. Intracranial mast cells (MCs) are likely to play a role in migraine headache genesis, and changes in the dural MC population might influence headache susceptibility. The present study thus tested the hypothesis that sex and ovarian hormones influence the density and phenotypic makeup of dural MCs. Methods Histochemistry combined with quantitative analyses was employed to investigate sex differences, estrous cycle and ovarian hormone influences on dural MCs density, phenotype and degranulation level in males and females rats. Results Our data show that in female rats, dural MC density fluctuates during the estrous cycle and is overall higher than in males. In ovariectomized rats, estradiol, but not progesterone, promoted an increase in dural MCs density. This effect was abolished by a splenectomy, suggesting estrogen-related recruitment of MCs from the spleen. Finally, our data suggest that the phenotypic make up of dural MCs, which represents the level of cellular maturity, is also governed by changes in estrogen levels. Conclusions Given the potential role of dural MCs in triggering headache, our data suggest that estrogen-related modulation of dural MC density and phenotypic makeup could play a role in mediating the higher frequency and severity of headaches, such as migraine, in women.

Postdural puncture headache (PDPH) is a recognized complication of neuraxial anesthesia. This case report documents 1 patient who developed PDPH following epidural anesthesia for postoperative pain control. The patient declined conventional treatments, including an epidural blood patch and intravenous caffeine. This report documents successful use of adjunct acupuncture for the management of PDPH. Additional research on acupuncture as a potential adjunctive therapy for PDPH is needed, particularly for patients who are reluctant to receive more invasive treatments. PMID:26937320

Migraine headache is one of the most common neurological disorders. The pathological conditions that directly initiate afferent pain signaling are poorly understood. In trigeminal neurons retrogradely labeled from the cranial meninges, we have recorded pH-evoked currents using whole-cell patch-clamp electrophysiology. Approximately 80% of dural-afferent neurons responded to a pH 6.0 application with a rapidly activating and rapidly desensitizing ASIC-like current that often exceeded 20nA in amplitude. Inward currents were observed in response to a wide range of pH values and 30% of the neurons exhibited inward currents at pH 7.1. These currents led to action potentials in 53%, 30% and 7% of the dural afferents at pH 6.8, 6.9 and 7.0, respectively. Small decreases in extracellular pH were also able to generate sustained window currents and sustained membrane depolarizations. Amiloride, a non-specific blocker of ASIC channels, inhibited the peak currents evoked upon application of decreased pH while no inhibition was observed upon application of TRPV1 antagonists. The desensitization time constant of pH 6.0-evoked currents in the majority of dural afferents was less than 500ms which is consistent with that reported for ASIC3 homomeric or heteromeric channels. Finally, application of pH 5.0 synthetic-interstitial fluid to the dura produced significant decreases in facial and hind-paw withdrawal threshold, an effect blocked by amiloride but not TRPV1 antagonists, suggesting that ASIC activation produces migraine-related behavior in vivo. These data provide a cellular mechanism by which decreased pH in the meninges following ischemic or inflammatory events directly excites afferent pain-sensing neurons potentially contributing to migraine headache.

A study using scanning electron microscopy showed that although the laminas forming the dura mater are concentric and parallel to the surface of the medulla, the fiber layers' orientations are different in each sub-lamina, dispelling the conventional knowledge that all the fibers of the dura are arranged in a parallel direction. Thus, this study evaluated the dural lesions produced by Whitacre and Quincke spinal needles in the external and internal surface of the dura mater of the lower spine area in an attempt to gain more insight into the pathophysiology of postdural puncture headaches (PDPH). The T11-L4 dural membranes from 5 fresh (immediately after extraction of organs for transplantation), male patients declared brain dead, ages 23, 46, 48, 55, and 60 years, were excised by anterior laminectomy. Morphologic orientation of the membrane and normal pH were maintained with an apparatus designed for this purpose. One hundred punctures (20 on each sample) at 90-degree angles were done with a new needle each time, 50 with 25-gauge Whitacre and 50 with 25-gauge Quincke needles. Half of the punctures with the Quincke needles were done with the bevel in parallel direction to the axis of the spinal cord, and the rest with the bevel perpendicular to it. Fixation in solutions of 2.5% glutaraldehyde phosphate buffer, followed by dehydration with acetone, was done 15 minutes after the punctures. After acetone was removed at ideal conditions of temperature and pressure, the specimens were then metallized with carbon followed by gold and inspected under a scanning electron microscope. Twenty-five of the Whitacre and 23 of the Quincke punctures were found for evaluation. There were no differences in the cross-sectional area of the punctures produced by the Whitacre or Quincke needles on the dura. The area of the dural lesions produced by 25-gauge Quincke needles, 15 minutes after they have been withdrawn, was 0.023 mm2 (confidence interval [CI] 95%, 0.015 to 0.027) in the

A comparison of a 25 G with a 29 G Quincke needle was performed in paediatric day case surgery. Sixty healthy children aged 1 year to 13 years were randomly allocated to have spinal anaesthesia with either 25 G or 29 G Quincke needle without an introducer needle. There was a failure rate of 10% with the 29 G spinal needle compared with 0% with the 25 G needle. The time needed to perform dural puncture was shorter using 25 G than 29 G needle, 22 (+/- 31)(SD) vs 59 (+/- 63) s. The time taken for cerebrospinal fluid to appear at the needle hub was also longer, 4 (+/- 3) vs 8 (+/- 5) s. The number of puncture attempts was similar, 1.2 (+/- 0.6) vs 1.4 (+/- 0.8), with 25 G and 29 G needle. Low back pain, 5 vs1, and nonpositional headache, 2 vs 4, after 25 G and 29 G needles, respectively, were the most frequent postoperative complaints. Mild postdural puncture headache occurred in one eight year old male patient in the 25 G group. In conclusion, lumbar puncture without introducer needle was possible with both needles. The puncture characteristics favoured the 25 G needle. A shorter needle could partly alleviate the difficulties with the 29 G needle.

Effects of Voluntary Locomotion and Calcitonin Gene-Related Peptide on the Dynamics of Single Dural Vessels in Awake Mice

PubMed Central

Gao, Yu-Rong

2016-01-01

The dura mater is a vascularized membrane surrounding the brain and is heavily innervated by sensory nerves. Our knowledge of the dural vasculature has been limited to pathological conditions, such as headaches, but little is known about the dural blood flow regulation during behavior. To better understand the dynamics of dural vessels during behavior, we used two-photon laser scanning microscopy (2PLSM) to measure the diameter changes of single dural and pial vessels in the awake mouse during voluntary locomotion. Surprisingly, we found that voluntary locomotion drove the constriction of dural vessels, and the dynamics of these constrictions could be captured with a linear convolution model. Dural vessel constrictions did not mirror the large increases in intracranial pressure (ICP) during locomotion, indicating that dural vessel constriction was not caused passively by compression. To study how behaviorally driven dynamics of dural vessels might be altered in pathological states, we injected the vasodilator calcitonin gene-related peptide (CGRP), which induces headache in humans. CGRP dilated dural, but not pial, vessels and significantly reduced spontaneous locomotion but did not block locomotion-induced constrictions in dural vessels. Sumatriptan, a drug commonly used to treat headaches, blocked the vascular and behavioral the effects of CGRP. These findings suggest that, in the awake animal, the diameters of dural vessels are regulated dynamically during behavior and during drug-induced pathological states. SIGNIFICANT STATEMENT The vasculature of the dura has been implicated in the pathophysiology of headaches, but how individual dural vessels respond during behavior, both under normal conditions and after treatment with the headache-inducing peptide calcitonin gene-related peptide (CGRP), is poorly understood. To address these issues, we imaged individual dural vessels in awake mice and found that dural vessels constricted during voluntary locomotion, and

To evaluate the influence of the shape of the needle tip on postdural puncture headache (PDPH) independent of the needle diameter, a 25-gauge Whitacre and a 25-gauge Quincke needle were compared. In a prospective, randomized, double-blind fashion, the study was carried out on 400 patients who received spinal anesthesia for operations of the lower extremities. The 25-gauge Whitacre needle (group 1) and the 25-gauge Quincke needle (group 2) were randomly assigned to the patients, 200 in each group. Patients were interviewed postoperatively on days 1, 3, 5, and 7 using a standardized questionnaire. Only postural headache was defined as PDPH. The intensity of both postural and nonpostural headache were quantified using a 4-point rating scale and a visual analog pain scale (VAS). Statistical analysis was performed with parametric and nonparametric tests when appropriate, p < or = 0.05 was considered as significant. There were no differences in age and sex distribution between the two groups. Significantly more patients in group 2 (8.5%) complained of PDPH than in group 1 (3%, p < or = 0.02). Duration of PDPH ranged from 1-3 days (median: 1) in group 1, and from 1-9 days (median: 3) in group 2. This difference closely approached significance (p = 0.058). The mean maximal intensity of PDPH was comparable in both groups. Severe PDPH occurred only in two patients of group 2. One of them required a blood patch. With respect to the nonpostural headache, no significant differences were seen. The use of a conical tipped Whitacre needle results in significantly less PDPH compared to a standard Quincke spinal needle of the same size.

Post-dural puncture headache and lumbar backache are related to needle gauge and type of point used. We aimed to determine whether the incidence of post-dural puncture headache and lumbar backache could be reduced by using fine gauge pencil-point Sprotte 27G and 29G needles. We also studied increases in technical difficulty with these needles and whether or not reducing needle gauge affected anesthetic quality. Three hundred eighty-nine patients undergoing orthopedic or lower abdominal surgery were randomly assigned to two groups for dural puncture using two Sprotte needles: 27G or 29G. We recorded time to perform puncture, number of re-insertations of the needle, number of times the technique was abandoned and anesthetic efficacy. On the second and seventh days, the patients were interviewed by telephone to check for the presence and severity of post-dural puncture headache or lumbar backache. The technical difficulty was greater with the Sprotte 29G needle, as shown by significant differences in time taken to perform the puncture and the number of re-insertions (p < 0.05). Anesthetic quality was the same in both groups and the percentage of failures was 0.5% for both. Five percent of patients in the 27G group and 3% in the 29G group experienced slight or moderate headache on the second day. No cases of severe cephalea were reported. Lumbar backache was reported on the second day by 26% and 18.5% of the patients in the 27G and 29G groups, respectively, but the rates decreased to 4.5% and 0.5% on the seventh day. The differences were significant, favoring the 29G needle. The use of 29G pencil-point needles can be recommended to reduce the incidence of headache and lumbar backache in the postoperative period, in spite of the greater technical difficulty involved, given that quality of anesthesia is maintained.

Supine recumbence has been widely performed to prevent post-lumbar puncture headache (PLPH). However, the optimal duration of supine recumbence is controversial. The aim of the study is to compare the occurrence of PLPH according to the duration of supine recumbence in patients with neurological disorders. A non-equivalent control/experimental pre-/post-test study design was used. Seventy consecutive patients were prospectively enrolled between July 2007 and July 2008. Thirty-five patients underwent supine recumbence for four hours after lumbar puncture (Group 1) and 35 patients underwent supine recumbence for one hour (Group 2). The overall frequency of PLPH was 31.4%. The frequency of PLPH was not significantly different between the Group 1 (28.6%) and Group 2 (34.3%) (P = 0.607). In patients with PLPH, the median severity (P = 0.203) and median onset time of PLPH (P = 0.582) were not significantly different between the two groups. In a logistic regression analysis, the previous history of post-lumbar puncture headache was a significant risk factor for the occurrence of PLPH (OR = 11.250, 95% CI: 1.10-114.369, P = 0.041). Our study suggests that short duration (one hour) of supine recumbence may be as efficient as long duration (four hours) of supine recumbence to prevent PLPH.

Diagnostic Lumbar Puncture is one of the most commonly performed invasive tests in clinical medicine. Evaluation of an acute headache and investigation of inflammatory or infectious disease of the nervous system are the most common indications. Serious complications are rare, and correct technique will minimise diagnostic error and maximise patient comfort. We review the technique of diagnostic Lumbar Puncture including anatomy, needle selection, needle insertion, measurement of opening pressure, Cerebrospinal Fluid (CSF) specimen handling and after care. We also make some quality improvement suggestions for those designing services incorporating diagnostic Lumbar Puncture. PMID:25075138

Post-dural puncture headache (PDPH) is a significant complication of spinal anaesthesia. Diameter and tip of the needle as well as the patient's age have been proven to be important determinants. The question of whether post-operative recumbency can reduce the risk of PDPH has not been answered uniformly. And besides, some studies referring to this subject reveal methodical failures, for example, as to clear definition and exact documentation of post-operative immobilization. Furthermore, fine-gauge needles (26G or more) have not been investigated yet. The first aim of our study was therefore to examine the role of recumbency in the prevention of PDPH under controlled conditions using thin needles. Secondly, we wanted to confirm the reported prophylactic effect of needles with a modified, atraumatic tip (Whitacre and Atraucan) by comparing them to Quincke needles of identical diameter. Most of the former investigators compared Quincke with atraumatic needles of different size regardless of the known influence of the diameter on PDPH. In a prospective study we included 481 consecutive patients undergoing a total of 500 orthopaedic operations under spinal anaesthesia. The latter was performed in a standardized manner (patient sitting, midline approach, needle with parallel bevel direction), using four different needles allocated randomly (26-gauge and 27-gauge needles with Quincke tip, 26-gauge Atraucan and 27-gauge Whitacre cannula). Half of the patients were instructed to stay in bed for 24 h (horizontal position without raising head), the others to get up as early as possible. An anaesthesiologist visited the patients on the fourth postoperative day or later and questioned them about headache and duration of recumbency. Additionally, the patients had to fill out a questionnaire 1 week after surgery. Any postural headache was considered as PDPH. The four groups of different needles had homogeneous demographic characteristics (see Table 1). A total of 47 patients (9

This study examined the incidence of failed spinal anesthesia and postdural puncture headache using a 27-gauge Whitacre and a 27-gauge Quincke needle in patients undergoing elective inpatient orthopedic procedures. The overall rate of failed spinal anesthesia was 8.5% [95% confidence interval (CI) = 4.6%-12.4%] (n = 17) in the Quincke group (n = 199) and 5.5% [95% CI = 2.3%-8.7%] (n = 11) in the Whitacre group (n = 199). This difference was not statistically significant. The overall incidence of postdural puncture headache (PDPH) was 0.8%; 1.1% [95% CI = 0%-2.4%] (n = 2) in the Quincke group and 0.5% [95% CI = 0%-1.5%] (n = 1) in the Whitacre group. These differences were not statistically significant. All headaches were classified as mild and resolved spontaneously with conservative management. The mean time for withdrawal of the stylet to appearance of cerebrospinal fluid was 10.8 +/- 6.9 s in the Quincke (n = 31) and 10.7 +/- 6.8 s in the Whitacre group (n = 33). These differences were not statistically significant. Our results suggest that both needles are associated with a very low incidence of PDPH and an incidence of failed anesthesia of 5.5%-8.5%.

The effect of different size (25-, 27- and 29-gauge) Quincke-type spinal needles on the incidence of insertion difficulties and failure rates was investigated in a randomised, prospective study with 300 patients. The needle size was randomised but the insertion procedure was standardised. The time to achieve dural puncture was significantly longer with the 29-gauge spinal needle compared with the larger bore needles and was due to the greater flexibility of the thin needle. However, the difference was less than 1 min and cannot be considered clinically significant. There were no significant differences between groups in the number of insertion attempts or failures and the same sensory level of analgesia was reached with all the needle sizes studied. Postoperatively, no postdural puncture headaches occurred in the 29-gauge spinal needle group, whilst in the 25- and 27-gauge needle groups, the postdural puncture headache rates were 7.4% and 2.1% respectively. The incidence of backache was similar in all study groups. We conclude that dural puncture with a 29-gauge spinal needle is clinically as easy as with larger bore needles and its use is indicated in patients who have a high risk of postdural puncture headache.

Headaches caused by decreased intracranial pressure: diagnosis and management.

PubMed

Mokri, Bahram

2003-06-01

More patients with spontaneous intracranial hypotension are now being diagnosed, and it is realized that most cases result from spontaneous cerebrospinal fluid leaks. A broader clinical and imaging spectrum of the disorder is recognized. This paper reviews new insights into the variability of clinical manifestations, imaging features, etiological factors, anatomy of leaks, and implications of these in patient management. Spontaneous intracranial hypotension should not be equated with post-lumbar puncture headaches. In a substantial minority of patients, headaches are not orthostatic and may mimic other types of headache. Additional diverse neurological manifestations may dominate the clinical picture and patients may occasionally have no headache at all. Reports on unusual presentations of the disorder continue to appear in the literature. Furthermore, additional imaging features of cerebrospinal fluid leaks are recognized. High-flow and slow-flow leaks may present diagnostic challenges, and require modification of diagnostic studies aimed at locating the site of the leak. Stigmata of connective tissue abnormality, especially abnormalities of fibrillin and elastin, are seen in a notable minority of patients, pointing to weakness of the dural sac as one of the etiological factors. After treatment of spontaneous intracranial hypotension, surgically or by epidural blood patch, a rebound and self-limiting intracranial hypertension may sometimes develop. In the past decade, interest in spontaneous intracranial hypotension has been rekindled, with a substantial growth of knowledge on various aspects of the disorder. We are in the learning phase, and new information will probably appear in the future, with notable diagnostic and therapeutic implications.

2016-01-01

This report aimed to describe the characteristics and impact of subdural hematoma (SDH) after labor epidural analgesia. Eleven obstetric patients had SDHs associated with the use of labor epidural analgesia over 7 years at a tertiary care hospital. Ten of 11 patients had signs consistent with postdural puncture headache before the diagnosis of SDH. Five patients (45%) had a recognized unintentional dural puncture, 1 (9%) had a combined spinal-epidural with a 24-gauge needle, and 5 (45%) had no recognized dural puncture. For 10 of the 11 cases, SDH was diagnosed at a mean of 4.1 days (range, 1-7 days) after performance of labor epidural analgesia; one case was diagnosed at 25 days. Ten (91%) of 11 cases had a second hospital stay for a mean of 2.8 days (range, 2-4 days) for observation, without further requirement for neurosurgical intervention. One case (9%) had decompressive hemicraniectomy after becoming unresponsive. The observed rate of labor epidural analgesia-associated SDH was 0.026% (11 in 42,969, approximately 1:3900), and the rate of SDH was 1.1% (5 in 437, approximately 1:87) if a recognized dural puncture occurred during epidural catheter placement. Subdural hematoma after labor epidural anesthesia is rare but potentially more common than historically estimated. Cases of postdural puncture headache after labor epidural anesthesia should be monitored closely for severe neurologic signs and symptoms that could herald SDH.

OBJECTIVE Cerebral venous pressure gradient (CVPG) from dural venous sinus stenosis is implicated in headache syndromes such as idiopathic intracranial hypertension (IIH). The incidence of CVPG in headache patients has not been reported. METHODS The authors reviewed all cerebral venograms with manometry performed for headache between January 2008 and May 2015. Patient demographics, headache etiology, intracranial pressure (ICP) measurements, and radiographic and manometric results were recorded. CVPG was defined as a difference ≥ 8 mm Hg by venographic manometry. RESULTS One hundred sixty-four venograms were performed in 155 patients. There were no procedural complications. Ninety-six procedures (58.5%) were for patients with IIH. The overall incidence of CVPG was 25.6% (42 of 164 procedures): 35.4% (34 of 96 procedures) in IIH patients and 11.8% (8 of 68 procedures) in non-IIH patients. Sixty procedures (36.6%) were performed in patients with preexisting shunts. Seventy-seven patients (49.7%) had procedures preceded by an ICP measurement within 4 weeks of venography, and in 66 (85.7%) of these patients, the ICP had been found to be elevated. CVPG was seen in 8.3% (n = 5) of the procedures in the 60 patients with a preexisting shunt and in 0% (n = 0) of the 11 procedures in the 77 patients with normal ICP (p < 0.001 for both). Noninvasive imaging (MR venography, CT venography) was assessed prior to venography in 112 (68.3%) of 164 cases, and dural venous sinus abnormalities were demonstrated in 73 (65.2%) of these cases; there was a trend toward CVPG (p = 0.07). Multivariate analysis demonstrated an increased likelihood of CVPG in patients with IIH (OR 4.97, 95% CI 1.71-14.47) and a decreased likelihood in patients with a preexisting shunt (OR 0.09, 95% CI 0.02-0.44). CONCLUSIONS CVPG is uncommon in IIH patients, rare in those with preexisting shunts, and absent in those with normal ICP.

The association of pituitary tumors and headache.

Levy, Miles J

Pituitary tumors may give rise to headache via numerous mechanisms. The traditional explanation for headache is dural stretch and cavernous sinus invasion, although this is not borne out by clinical studies. Certain functional pituitary tumors are associated with headache, notably growth hormone and prolactin-secreting tumors. The observation that somatostatin analogues can have a dramatic analgesic effect in acromegaly suggests that biochemical properties of the tumor may be important. The genetic predisposition of the patient to primary headache also determines whether headache occurs with pituitary tumors. This article attempts to outline the clinical features, management strategies, and key academic questions regarding the subject of pituitary tumors and headache.

Abstract Background: Postdural puncture headache (PDPH), mainly resulting from the loss of cerebral spinal fluid (CSF), is a well-known iatrogenic complication of spinal anesthesia and diagnostic lumbar puncture. Spinal needles have been modified to minimize complications. Modifiable risk factors of PDPH mainly included needle size and needle shape. However, whether the incidence of PDPH is significantly different between cutting-point and pencil-point needles was controversial. Then we did a meta-analysis to assess the incidence of PDPH of cutting spinal needle and pencil-point spinal needle. Methods: We included all randomly designed trials, assessing the clinical outcomes in patients given elective spinal anesthesia or diagnostic lumbar puncture with either cutting or pencil-point spinal needle as eligible studies. All selected studies and the risk of bias of them were assessed by 2 investigators. Clinical outcomes including success rates, frequency of PDPH, reported severe PDPH, and the use of epidural blood patch (EBP) were recorded as primary results. Results were evaluated using risk ratio (RR) with 95% confidence interval (CI) for dichotomous variables. Rev Man software (version 5.3) was used to analyze all appropriate data. Results: Twenty-five randomized controlled trials (RCTs) were included in our study. The analysis result revealed that pencil-point spinal needle would result in lower rate of PDPH (RR 2.50; 95% CI [1.96, 3.19]; P < 0.00001) and severe PDPH (RR 3.27; 95% CI [2.15, 4.96]; P < 0.00001). Furthermore, EBP was less used in pencil-point spine needle group (RR 3.69; 95% CI [1.96, 6.95]; P < 0.0001). Conclusions: Current evidences suggest that pencil-point spinal needle was significantly superior compared with cutting spinal needle regarding the frequency of PDPH, PDPH severity, and the use of EBP. In view of this, we recommend the use of pencil-point spinal needle in spinal anesthesia and lumbar puncture. PMID:28383416

Acute severe headache indicative of subarachnoid haemorrhage (SAH), but without the requisite proof, is defined as thunderclap. A special pathophysiological mechanism for the development of this headache is not known as yet. This retrospective study comprised 84 patients. All had the typical clinical signs of a SAH, but cranial computer tomography and lumbar puncture excluded this diagnosis. In 82% of these patients the headache was classified according to aetiologically defined symptomatic groups. One patient with headache of vascular aetiology had an angiographically proven, but not ruptured aneurysm. No definite cause for the headache was found in 18% of cases. None of the patients followed up over a period of between 12 months and 6 years developed SAH or any other severe neurological disorder. 9% reported repeat of the headache event. Thunderclap headache seems to be only a descriptive term for patients with symptoms typical of a SAH without signs of bleeding. Thunderclap headache has no diagnostic or prognostic specificity and therefore we recommend use of this term only as a description of the headache characteristic. Thunderclap headache is not a predictor of a future SAH. Cerebral angiography should be restricted to cases with neurological deficits.

Postdural puncture headache (PDPH) is a relatively common complication after regional anesthesia, especially in younger people, bothersome to patients and needs prophylaxis to prevent this complication. This study was conducted aiming to determine the preventive effect of dexamethasone plus caffeine and acetaminophen on relative frequency and intensity of PDPH after spinal anesthesia. In a clinical trial study, 90 candidates for the lower extremities orthopedic elective operation were divided into two groups of 45 individuals each. Intervention group received the compound of 500 mg acetaminophen +65 mg oral caffeine +8 mg venous dexamethasone an hour before spinal blocking, and the control group received placebo tablets + a dexamethasone equivalent volume of venous normal saline. The level of postoperative headache at the time of entrance to recovery and discharge, 6, 12, 24, 48, and 72 h postoperatively were measured based on Visual Analog Scale criterion in the two groups and then compared with each other. During the study, 24 patients in the control group and 17 patients in the intervention group were afflicted with headache; however, with no significant difference (P = 0.14). Total frequency of headache incidence was 35 times in the control group and 27 times in the intervention group (P = 0.32). Though the taking of acetaminophen + caffeine + dexamethasone is associated with a decrease in headache intensity and duration and decrease in PDPH incidence, compared with placebo, however, no essentially and statistically significant effect was produced.

Complications after LP related to needle type: pencil-point versus Quincke.

Aamodt, A; Vedeler, C

2001-06-01

We studied the incidence of complications after diagnostic lumbar puncture (LP) related to needle type. A 5 months' observational study of routine diagnostic LP in 83 patients was conducted. Significantly more headache was observed after LP using thicker cutting needles (20G Quincke) compared with thinner cutting or non-cutting needles (22G Quincke or pencil-point). No significant difference in complications after LP was found between the 22G Quincke and pencil-point needles. The size of the needle and not the needle shape seems to be the main determinant for post-dural puncture headache (PDPH).

Patient Male, 32 FINAL DIAGNOSIS: Dural arterio-venous fistula Symptoms: Eye redness • post-trauma headache • tinnitus - Clinical Procedure: Fistula embolization Specialty: Neurology. Mistake in diagnosis. A dural arteriovenous fistula (DAVF), is an abnormal direct connection (fistula) between a meningeal artery and a meningeal vein or dural venous sinus. The pathogenesis of DAVF still remains unclear. Sinus thrombosis, head trauma, chronic central nervous system, hypercoagulable state, surgery, and hormonal influence are the pre-disposing factors that initiate this disease. The symptoms experienced by the patient will depend on the location of the fistula. Thirty-two year old Hispanic male who presented one day after a rear ended motor vehicle collision (MVC) with a severe throbbing headache in the left parietal region, left eye redness but no retro-orbital pain and tinnitus in the left ear. He was initially misdiagnosed to have a carotid-cavernous fistula but upon cerebral angiogram was actually diagnosed with a dural arterio-venous fistula in the posterior fossa venous system followed by successful embolization of the fistula. A cerebral angiography is the gold standard for detection and characterization of a DAVF and will distinguish it from a CCF. Endovascular surgery involves a catheter-based technique for embolization of the lumen of arteries feeding the DAVF, or directly into the vein draining the DAVF. It is very important to recognize the typical findings of patients presenting with a DAVF then quickly proceeding with a cerebral angiogram to determine the exact location of the fistula and the appropriate treatment plan. By diagnosing and treating a DAVF as early as possible, the associated fatal complications can be averted.

A case of tentorial dural AVM was reported. A 52 years old man came to the Jichi Medical School hospital on July 29, 1974, with the chief complaints of intermittent left exophthalmos, diplopia and left blepharoptosis, which had been noted since March of 1974. He had episodes of severe headache attack since 3 years prior to the hospital visit. Angiography done at the out-patient department demonstrated the dural AVM with the nidus in the left tentorium. The nidus was fed by the left posterior middle meningeal artery, the dural branch of the left occipital artery, the left posterior cerebral artery, the left superior cerebellar artery and the dural branches of vertebral artery. It was drained to the vein of Labbé and the two cortical veins of the occipital lobe. He was appointing admission under the diagnosis of dural AVM, but he had an apopleptic attack three days before the appointed date, so was admitted in emergency. Neurological examination on admission: The patient was in drowsy state, papilledema on the both sides and right hemiparesis including the face were noted. The bruit was not audible. Left CAG revealed intracerebral hematoma in the left tempotal lobe, so that the removal of the intracerebral hematoma and the middle meningeal artery ligation were carried out after his general condition improved, on October 18, 1974. On October 30, 1974, the second operation was performed in an attempt of the radical excision of the AVM nidud. But, unfortunately, the patient fell into the shock state so that the operation had to be stopped at the stage of the ligation of the feeders running in the dura of the posterior fossa. The third operation was done on February 19, 1975. The AVM nidus was removed with the left transverse sinus and a part of tentorium. He was discharged on March 3, 1975, with only the right homonymous hemianopsia. Nine months after his discharge, there was no sign of recurrence of AVM. The left transverse sinus was almost occupied with AVM tissue

Comparisons of Quincke needles and non traumatic "pencil point" needles in recent years have reported lower rates of post dural puncture headache using the later type. Our new understanding of the morphology of the human dura mater motivated us to study dural lesions caused by the Whitacre 25 G and Quincke 26 G needles, using scanning electron microscopy with the aim of determining whether there is an anatomic basis for the different outcomes. The dura mater from three fresh cadavers of individuals aged 65, 70 and 72 years were punctured 40 times at an angle of 90 degrees each time. The Whitacre 25 G needle was used for 20 punctures and the Quincke 26 G needle was used for the other 20. Half the punctures were performed with the bevel in the parallel alignment and the other half with the bevel perpendicular to the spinal column. Fifteen min after causing the punctures, specimens were fixed in solutions of glutaraldehyde phosphate buffer and dehydrated in acetone. After critical point removal of the acetone, after the specimens were treated with carbon and metallized with gold. The lesions were examined externally and internally and expressed as the ratio of area of lesion to diameter of the needle that had caused them. Whitacre needle: each lesion consisted in the superimposition of multiple damaged layers that started to close individually. After 15 min the outermost layers were 90% closed and the innermost ones had closed entirely. Layers in the arachnoid surface of the dura mater had closed from 86 to 88%, while deeper layers in the thick part had closed 97 to 98%. Quincke needle: lesions were V-shaped or half-moon shaped, much like the opening formed by a can opener, on both the external and internal surfaces. Alignment of the bevel of the needle parallel to the spinal column did not lead to a different shape of puncture. After 15 min the lesions had closed 94 to 95% on the epidural surface and 95 to 96% on the arachnoid side, a difference attributable to the

Posterior reversible encephalopathy syndrome following a thoracic discectomy-induced dural leak: case report.

PubMed

Shields, Lisa B E; Johnson, John R; Shields, Christopher B

2016-11-01

Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiological syndrome characterized by headaches, altered mental status, seizures, and visual disturbances. Classic MRI findings include white matter changes of the parieto-occipital regions. This syndrome has been encountered in myriad medical illnesses, including hypertension, preeclampsia/eclampsia, and immunosuppressive conditions. While the pathogenesis of the disorder is unclear, vasoconstriction and hypoperfusion leading to brain ischemia and vasogenic edema have been implicated as potential mechanisms. The authors present, to the best of their knowledge, the first case of PRES following a thoracic spinal surgery-induced dural leak noted on resection of the fifth rib during a thoracotomy for a T4-5 discectomy. Brain MRI revealed large areas of increased FLAIR and T2 hyperintensity in the superior posterior frontal lobes, superior and medial parietal lobes, and bilateral occipital lobes. Following repair of the CSF leak, the patient's symptoms resolved. Spinal surgeons should be alert to the potentially life-threatening condition of PRES, especially in a hypertensive patient who experiences surgery-induced dural leakage. The development of a severe positional headache with neurological signs is a red flag that suggests the presence of PRES. Prompt attention to the diagnosis and treatment of this condition by repairing the dural leak via surgery or expeditious blood patch increases the likelihood of a favorable outcome.

Reports have indicated that there are less postoperative complaints after the use of pencil pointed spinal needles. We compared a 24G Sprotte needle with a 27G Quincke needle in a randomised study of 200 healthy patients (49% females), aged 15-46 years. Four patients (2%) reported postdural puncture headache, three with the 24G Sprotte needle and one with the 27G Quincke needle. Thirteen patients (7%) suffered with nonspecific headache, with no significant difference between the two groups. Of the 57 (29%) who reported backpain, a significantly higher proportion had received spinal anaesthesia with the Sprotte needle (OR = 2.06). There was a significantly higher incidence of insufficient blocks after dural puncture with the Sprotte needle. Ease of needle insertion and number of puncture attempts was the same for both needle types.

Continuous Spinal Anesthesia for Obstetric Anesthesia and Analgesia

PubMed Central

Veličković, Ivan; Pujic, Borislava; Baysinger, Charles W.; Baysinger, Curtis L.

2017-01-01

The widespread use of continuous spinal anesthesia (CSA) in obstetrics has been slow because of the high risk for post-dural puncture headache (PDPH) associated with epidural needles and catheters. New advances in equipment and technique have not significantly overcome this disadvantage. However, CSA offers an alternative to epidural anesthesia in morbidly obese women, women with severe cardiac disease, and patients with prior spinal surgery. It should be strongly considered in parturients who receive an accidental dural puncture with a large bore needle, on the basis of recent work suggesting significant reduction in PDPH when intrathecal catheters are used. Small doses of drug can be administered and extension of labor analgesia for emergency cesarean delivery may occur more rapidly compared to continuous epidural techniques. PMID:28861414

A potential nitrergic mechanism of action for indomethacin, but not of other COX inhibitors: relevance to indomethacin-sensitive headaches.

Non-steroidal anti-inflammatory drugs (NSAIDs) that act as cyclo-oxygenase (COX) inhibitors are commonly used in the treatment of a range of headache disorders, although their mechanism of action is unclear. Indomethacin is of particular interest given its very special effect in some primary headaches. Here the in vivo technique of intravital microscopy in rats has been utilised as a model of trigeminovascular nociception to study the potential mechanism of action of indomethacin. Dural vascular changes were produced using electrical (neurogenic) dural vasodilation (NDV), calcitonin gene-related peptide (CGRP) induced dural vasodilation and nitric oxide (NO) induced dural vasodilation using NO donors. In each of these settings the effect of intravenously administered indomethacin (5 mg kg(-1)), naproxen (30 mg kg(-1)) and ibuprofen (30 mg kg(-1)) was tested. All of the tested drugs significantly inhibited NDV (between 30 and 52%). Whilst none of them was able to inhibit CGRP-induced dural vasodilation, only indomethacin reduced NO induced dural vasodilation (35 ± 7%, 10 min post administration). We conclude NSAIDs inhibit release of CGRP after NDV without an effect on CGRP directly. Further we describe a differentiating effect of indomethacin inhibiting nitric oxide induced dural vasodilation that is potentially relevant to understanding its unique action in disorders such as paroxysmal hemicrania and hemicrania continua.

Objective This report describes the characteristics and impact of subdural hematoma (SDH) after labor epidural analgesia. Case Reports Eleven obstetric patients had subdural hematomas (SDH) associated with the use of labor epidural analgesia over 7 years at a tertiary care hospital. Ten of 11 patients had signs consistent with post-dural puncture headache (PDPH) prior to the diagnosis of SDH. Five patients (45%) had a recognized unintentional dural puncture, 1 (9%) had a combined spinal-epidural with a 24-gauge needle, and 5 (45%) had no recognized dural puncture. For 10 of the 11 cases, SDH was diagnosed an average of 4.1 (range 1–7) days after performance of labor epidural analgesia; one case was diagnosed at 25 days. Ten of 11 (91%) cases had a second hospital stay for an average of 2.8 (range 2–4) days for observation, without further requirement for neurosurgical intervention. One case (9%) had decompressive hemicraniectomy after becoming unresponsive. The observed rate of labor epidural analgesia-associated SDH was 0.026% (11 in 42,969, about 1:3900), and the rate of SDH was 1.1% (5 in 437, about 1:87) if a recognized dural puncture occurred during epidural catheter placement. Conclusions SDH after labor epidural anesthesia is rare, but potentially more common than historically estimated. Cases of PDPH after labor epidural anesthesia should be monitored closely for severe neurologic signs and symptoms that could herald SDH. PMID:27512937

Objective: The aim of this study is to assess deformation of the tip and deflection from the axis of 22-gauge Quincke needles when they are used for diagnostic lumbar puncture (LP). Thus, it can be determined whether constructional alterations of needles are important for predicting clinical problems after diagnostic LP. Materials and Methods: The 22-gauge Quincke needles used for diagnostic LP were evaluated. A specially designed protractor was used for measurement and evaluation. Waist circumference was measured in each patient. Patients were questioned about headaches occurring after LP. Results: A total of 115 Quincke-type spinal needles used in 113 patients were evaluated. No deflection was detected in 38 (33.1%) of the needles. Deflection between 0.1° and 5° occurred in 43 (37.3%) of the needles and deflection ≥ 5.1° occurred in 34 patients (29.6%). Forty-seven (41.5%) patients experienced post lumbar puncture headache (PLPH) and 13 (11.5%) patients experienced intracranial hypotension (IH). No statistically significant correlation between the degree of deflection and headache was found (P > 0.05). Epidural blood patch was performed for three patients. Deformity in the form of bending like a hook occurred in seven needles and IH occurred in six patients using these needles. Two of the needles used in three patients requiring blood patch were found to be bent. Conclusion: Deformation of needles may increase complications after LP. Needle deformation may lead to IH. In case of deterioration in the structure of the needle, termination of the puncture procedure and the use of a new needle could reduce undesirable clinical consequences, especially IH.

Interlaminar lumbar puncture and cervical puncture may not be ideal in all circumstances. Recently, we have used a transforaminal approach in selected situations. Between May 2016 and December 2017, twenty-six transforaminal lumbar punctures were performed in 9 patients (25 CT-guided, 1 fluoroscopy-guided). Seven had spinal muscular atrophy and were referred for intrathecal nusinersen administration. In 2, CT myelography was performed via transforaminal lumbar puncture. The lumbar posterior elements were completely fused in 8, and there was an overlying abscess in 1. The L1-2 level was used in 2; the L2-3 level, in 10; the L3-4 level, in 12; and the L4-5 level, in 2 procedures. Post-lumbar puncture headache was observed on 4 occasions, which resolved without blood patching. One patient felt heat and pain at the injection site that resolved spontaneously within hours. One patient had radicular pain that resolved with conservative treatment. Transforaminal lumbar puncture may become an effective alternative to classic interlaminar lumbar puncture or cervical puncture. © 2018 by American Journal of Neuroradiology.

Many reports have shown a low incidence of postdural puncture headache (PDPH) and other complaints in young children. The objective of this open-randomized, prospective, parallel group study was to compare the use of a cutting point spinal needle (22-G Quincke) with a pencil point spinal needle (22-G Whitacre) in children. We studied the puncture characteristics, success rate and incidence of postpuncture complaints in 57 children, aged 8 months to 15 years, following 98 lumbar punctures (LP). The patient/parents completed a diary at 3 and 7 days after LP. The response rate was 97%. The incidence of PDPH was similar, 15% in the Quincke group and 9% in the Whitacre group (P=0.42). The risk of developing a PDPH was not dependent on the age (r < 0.00, P=0.67). Eight of the 11 PDPHs developed in children younger than 10 years, the youngest being 23-months-old.

Introduction Lumbar puncture is one of the oldest and most commonly performed procedures in medicine, used to diagnose and treat disease. Headache following lumbar puncture remains a frequent complication, causing significant patient discomfort and often requiring narcotic analgesia or invasive therapy. Needle tip design has been proposed to affect the incidence of headache postlumbar puncture, with pencil-point ‘atraumatic’ needles thought to reduce its incidence in comparison to bevelled ‘traumatic’ needles. Despite this, the use of atraumatic needles and knowledge of their existence remains significantly limited among clinicians. This study will systematically review the evidence on atraumatic lumbar puncture needles and compare them with traumatic needles across a variety of clinical outcomes. Methods and analyses We will include published randomised controlled trials (RCTs), observational studies and abstracts, with no publication type or language restrictions. Search strategies will be designed to peruse the MEDLINE, EMBASE, Web of Science, ClinicalTrials.gov, CINAHL, WHO Clinical Trials Database and Cochrane Library databases. We will also implement strategies to search the grey literature. 3 reviewers will thoroughly and independently examine the search results, complete data abstraction and conduct quality assessment. Included RCTs will be assessed using the Cochrane risk of bias assessment tool and eligible observational studies will be examined using the Newcastle-Ottawa Scale. We will examine the outcomes of: headache and its type, intensity, duration and treatment; backache; success rate; hearing disturbance and nerve root irritation. The primary outcome will be the incidence of postdural puncture headache. We will calculate pooled estimates, relative risks for dichotomous outcomes and weighted mean differences for continuous outcomes, with corresponding 95% CIs. Statistical heterogeneity will be measured using Cochran's Q test and quantified

The purpose of this study was to determine whether the 26-gauge Atraucan needle shows any benefit on the incidence of postdural puncture headache (PDPH) and back pain as compared with the 27-gauge Quincke needle. We investigated 388 patients, 171 men and 217 women, who were receiving spinal anesthesia for subumbilical surgery. We compared spinal anesthesia via the 27-gauge Quincke needle in 202 patients (group Q) and via the 26-gauge Atraucan needle in 186 patients (group A). The incidence of PDPH was 2.97% (6 of 202) in group Q and 2.69% (5 of 186) in group A. The incidence of back pain was 4.95% (10 of 202) in group Q and 5.91% (11 of 186) in group A. There was no statistically significant association of needle type, age, or sex with the incidence of PDPH and back pain. Both needles are associated with very low incidences of PDPH and back pain, which are not affected by which needle is chosen.

A 57-year-old woman was admitted with recurrent episodes of right frontal headache. Head magnetic resonance imaging (MRI) revealed extensive thickening and enhancement of the right frontal dura, muscle and fascia, as well as abnormal signal intensity and enhancement of bone marrow at the lesions. Synovitis-acne-pustulosis-hyperostosis osteomyelitis (SAPHO) syndrome was diagnosed based on the patient's 8-year history of treatment of palmoplantar pustulosis and abnormal accumulations in the right temporal, sternum, and left medial clavicula on bone scintigraphy. SAPHO syndrome may be associated with skull lesions, which can contribute to the onset of repeated headache or dural thickening, thus these symptoms should be recognized as manifestations of this syndrome.

The case of a 10-year-old female with Marfan syndrome and postural headache secondary to spontaneous intracranial hypotension is described. The patient was found to have multiple dural ectasias and a cerebrospinal fluid leak at the left cervicothoracic junction. Her presentation, diagnostic work-up, and management are reviewed, and the relevant literature is discussed. Spontaneous intracranial hypotension secondary to cerebrospinal fluid leaks from dural ectasia should be recognized as a potential complication in children with Marfan syndrome and other connective tissue diseases.

Metastatic Ewing's sarcoma to the central nervous system is an uncommon condition and debate concerning the true origin of its metastases is still up to date. To the best of our knowledge, only two cases of dural metastatic Ewing's sarcoma have been published in the English medical literature. We present an additional case in a 24-year-old female and discuss the pathogenesis of these unusual tumors with review of the relevant literature concerning their treatment and outcome. A 24-year-old female with previous history of pelvis Ewing's sarcoma and recently discovered lung metastases, presented with moderate headache for the past 2 weeks and weakness in her left leg for the past 2 days. Computed tomography scan and magnetic resonance imaging revealed an extra-axial right frontoparietal mass invading the superior sagittal sinus but with clear delineation with brain parenchyma. Imaging features were suggestive of a meningioma as no abnormalities in the skull abutting to the tumor were noted. The patient underwent surgical removal of her tumor. Near total resection was achieved and histological examination showed evidence of metastatic Ewing's sarcoma. Postoperative adjuvant radiation and chemotherapy were administered. The patient improved well postoperatively with full recovery of her motor weakness. She is symptom free with no signs of progression, at most recent follow-up, 8 months after surgery. Despite its rarity, metastatic Ewing's sarcoma must be considered in the differential diagnosis of extra-axial dural masses particularly meningiomas.

This systematic review summarizes the existing data on headache and pregnancy with a scope on clinical headache phenotypes, treatment of headaches in pregnancy and effects of headache medications on the child during pregnancy and breastfeeding, headache related complications, and diagnostics of headache in pregnancy. Headache during pregnancy can be both primary and secondary, and in the last case can be a symptom of a life-threatening condition. The most common secondary headaches are stroke, cerebral venous thrombosis, subarachnoid hemorrhage, pituitary tumor, choriocarcinoma, eclampsia, preeclampsia, idiopathic intracranial hypertension, and reversible cerebral vasoconstriction syndrome. Migraine is a risk factor for pregnancy complications, particularly vascular events. Data regarding other primary headache conditions are still scarce. Early diagnostics of the disease manifested by headache is important for mother and fetus life. It is especially important to identify "red flag symptoms" suggesting that headache is a symptom of a serious disease. In order to exclude a secondary headache additional studies can be necessary: electroencephalography, ultrasound of the vessels of the head and neck, brain MRI and MR angiography with contrast ophthalmoscopy and lumbar puncture. During pregnancy and breastfeeding the preferred therapeutic strategy for the treatment of primary headaches should always be a non-pharmacological one. Treatment should not be postponed as an undermanaged headache can lead to stress, sleep deprivation, depression and poor nutritional intake that in turn can have negative consequences for both mother and baby. Therefore, if non-pharmacological interventions seem inadequate, a well-considered choice should be made concerning the use of medication, taking into account all the benefits and possible risks.

Case report: delayed presentation of postural headache in an adolescent girl after microscopic lumbar discectomy.

To discuss the diagnostic and therapeutic challenges presented by an adolescent girl with delayed postural headaches and photophobia that occurred three months after an apparently uncomplicated microscopic lumbar discectomy. A previously healthy girl was admitted to our hospital with a one-week history of an unremitting, frontal-retroorbital postural headache and photophobia. Three months before admission, the patient had undergone a L5-S1 left hemilaminotomy and foraminotomy with microdiscectomy for excision of a herniated intervertebral disc. Conservative treatment failed to provide symptomatic relief. Cranial magnetic resonance imaging showed enhancement of the pachymeninges, consistent with intracranial hypotension. A chronic cerebrospinal leak was identified by high-resolution computed tomography (CT) myelography. Epidural blood patches were performed, with and without CT guidance, that provided temporary relief of the patient's symptoms; however, direct suture plication of the dural tear was eventually required for definitive treatment. This case emphasizes that delayed presentation of dural injury may occur after lumbar surgery and describes the potential therapeutic implications for this unusual complication.

[Incidence of postmyelography syndrome and postmyelography complaints after lumbar puncture with the Sprotte pencil-like needle in comparison with the Quincke needle].

Myelography in combination with a postmyelography CT is an important presurgical examination because of its excellent visualisation of the disc, the bone and the contrast-filled dura. Side effects after myelography can be observed in up to 50% of patients. The pathophysiological mechanism is thought to be increased cerebrospinal fluid leakage at the puncture site. Since the introduction by Sprotte in 1979 of the pencil-point needle, a modification of Whitacre's needle, fewer complaints after lumbar puncture have been reported. The aim of the study was to examine the influence of two types of needle points and the temperature (37 degrees C vs 21 degrees C) of the contrast medium (CM; iotrolan, Isovist) on the incidence of side effects of lumbar puncture for myelography. In a prospective randomized trial the incidence of complaints after lumbar puncture with intrathecal CM application was evaluated by the use of a 21-G pencil-point needle as modified by Sprotte compared to our usual 22-G needle with a Quincke bevel. Some 412 patients (201 female, 211 male; mean age 54.05 +/- 7.4 years) were investigated. Directly after examination and 1. 3 and 5 days later the patients were questioned about complaints (headache, neck stiffness nausea, vomiting, buzzing in the ear and dizziness). The results were tested by the chi square test. A significantly lower incidence of complaints was seen after lumbar puncture with the pencil-point needle/Quincke needle (headache: 6.3%/18.9%, P < 0.0001; headache lasting 3 days: 0.5%/7.8%, P < 0.0001; headache lasting 5 days: 0%/2.4%, P = 0.0305; nausea: 0%/4.9%, P = 0.0009; vomiting: 0%/3.4%, P = 0.0009; dizziness: 0%/3.4%, P = 0.0074; neck stiffness: 0%/3.4%, P = 0.0074). The temperature of the CM had no influence on the complaints. No influence was seen on the quality of the myelogram. No relation to sex and age was found. Complaints after lumbar puncture and myelography are caused by the cerebrospinal fluid leakage at the puncture site

The best method for identifying the epidural space for neuraxial blocks is controversial. We conducted this meta-analysis to test the hypothesis that loss of resistance with liquid reduces complications with epidural placement. The MEDLINE, EMBASE, and Cochrane databases were searched for prospective, randomized studies comparing air versus liquid as the medium for loss of resistance during epidural space identification in adults. Data were abstracted from 5 studies (4 obstetric and 1 nonobstetric) (n = 4422 patients) that met inclusion criteria and analyzed for the following 6 outcomes: difficult catheter insertion, paresthesia, intravascular catheter insertion, accidental dural puncture, postdural puncture headache, and partial block. The overall risk differences for adverse outcome between the different mediums were not statistically different for the obstetric population. A small, but statistically significant, risk difference for postdural puncture headache was observed when fluid was used during epidural placement for chronic pain management. Larger studies that overcome limitations of heterogeneity across studies and a relatively infrequent occurrence of complications are required to determine the optimal medium for loss of resistance during epidural block.

We report 2 very unusual cases of thunderclap headache complicating minimally invasive medical procedures. In the first case headache developed as the consequence of a pneumocephalus caused by an inadvertent intrathecal puncture during oxygen-ozone therapy for lumbar disk herniation. The second case involved intracranial hypotension, caused by the persistence of the needle, used for epidural anesthesia, and then penetrated in the subarachnoid space.

Migraine is one of the most common and most disabling disorders. Between attacks, migraine patients are otherwise normal but are sensitized to non-noxious events known as triggers. The purpose of these studies was to investigate whether a headache-like event causes sensitization, or priming, to subsequent subthreshold events. Interleukin-6 (IL-6) was applied to the rat cranial dura mater which produced cutaneous facial and hindpaw allodynia that lasted 24 hours. At 72-hours, IL-6 treated rats developed allodynia in response to dural stimulation with either a pH 6.8 or pH 7.0 solution and to a systemic nitric oxide (NO) donor, a well-known migraine trigger. Vehicle-treated rats did not respond to either pH stimulus nor to the NO donor, demonstrating that IL-6 exposure primes rats to subthreshold stimuli. Inhibitors of brain-derived neurotrophic factor (BDNF) signaling given either systemically or intracisternally 24-hours after IL-6 eliminated responses to dural pH stimulation at 72 hours. Additionally, intracisternal administration of BDNF without prior dural stimulation produced allodynia and once resolved, animals were primed to dural pH 6.8/pH 7.0 and a systemic NO donor. Finally, hindpaw IL-6 produced paw allodynia but not priming to paw injection of pH 7.0 at 72 hours demonstrating differences in priming depending on location. These data indicate that afferent input from the meninges produces BDNF-dependent priming of the dural nociceptive system. This primed state mimics the interictal period of migraine where attacks can be triggered by normally non-noxious events and suggests that BDNF-dependent plasticity may contribute to migraine.

Sensitization of dural afferents underlies migraine-related behavior following meningeal application of interleukin-6 (IL-6)

PubMed Central

2012-01-01

Background Migraine headache is one of the most common neurological disorders, but the pathophysiology contributing to migraine is poorly understood. Intracranial interleukin-6 (IL-6) levels have been shown to be elevated during migraine attacks, suggesting that this cytokine may facilitate pain signaling from the meninges and contribute to the development of headache. Methods Cutaneous allodynia was measured in rats following stimulation of the dura with IL-6 alone or in combination with the MEK inhibitor, U0126. The number of action potentials and latency to the first action potential peak in response to a ramp current stimulus as well as current threshold were measured in retrogradely-labeled dural afferents using patch-clamp electrophysiology. These recordings were performed in the presence of IL-6 alone or in combination with U0126. Association between ERK1 and Nav1.7 following IL-6 treatment was also measured by co-immunoprecipitation. Results Here we report that in awake animals, direct application of IL-6 to the dura produced dose-dependent facial and hindpaw allodynia. The MEK inhibitor U0126 blocked IL-6-induced allodynia indicating that IL-6 produced this behavioral effect through the MAP kinase pathway. In trigeminal neurons retrogradely labeled from the dura, IL-6 application decreased the current threshold for action potential firing. In response to a ramp current stimulus, cells treated with IL-6 showed an increase in the numbers of action potentials and a decrease in latency to the first spike, an effect consistent with phosphorylation of the sodium channel Nav1.7. Pretreatment with U0126 reversed hyperexcitability following IL-6 treatment. Moreover, co-immunoprecipitation experiments demonstrated an increased association between ERK1 and Nav1.7 following IL-6 treatment. Conclusions Our results indicate that IL-6 enhances the excitability of dural afferents likely via ERK-mediated modulation of Nav1.7 and these responses contribute to migraine

MRV is an important blood vessel imaging and diagnostic tool for the evaluation of stenosis, occlusions, or aneurysms. However, an accurate image-processing tool for vessel comparison is unavailable. The purpose of this study was to develop and test an automated technique for vessel cross-sectional analysis. An algorithm for vessel cross-sectional analysis was developed that included 7 main steps: 1) image registration, 2) masking, 3) segmentation, 4) skeletonization, 5) cross-sectional planes, 6) clustering, and 7) cross-sectional analysis. Phantom models were used to validate the technique. The method was also tested on a control subject and a patient with idiopathic intracranial hypertension (4 large sinuses tested: right and left transverse sinuses, superior sagittal sinus, and straight sinus). The cross-sectional area and shape measurements were evaluated before and after lumbar puncture in patients with idiopathic intracranial hypertension. The vessel-analysis algorithm had a high degree of stability with <3% of cross-sections manually corrected. All investigated principal cranial blood sinuses had a significant cross-sectional area increase after lumbar puncture (P ≤ .05). The average triangularity of the transverse sinuses was increased, and the mean circularity of the sinuses was decreased by 6% ± 12% after lumbar puncture. Comparison of phantom and real data showed that all computed errors were <1 voxel unit, which confirmed that the method provided a very accurate solution. In this article, we present a novel automated imaging method for cross-sectional vessels analysis. The method can provide an efficient quantitative detection of abnormalities in the dural sinuses. © 2016 by American Journal of Neuroradiology.

Patients with esophageal squamous cell carcinoma generally present at an advanced stage at the time of diagnosis. The most common sites of visceral metastasis are the lung, liver and bone, but brain and bone marrow involvement is exceedingly rare. Herein, we report a 62-year-old man with a 4-wk history of progressive low back pain with radiation to bilateral lower legs, dysphagia and body weight loss. Esophageal squamous cell carcinoma with regional lymph node, liver and bone metastases was diagnosed. He underwent concurrent chemoradiotherapy and got a partial response. Four months later, he complained of headache, diplopia and severe hearing impairment in the left ear. There was no evidence for bacterial, fungal, tuberculous infection or neoplastic infiltration. Magnetic resonance imaging of the brain demonstrated thickening and enhancement of bilateral pachymeninges and multiple enhancing masses in bilateral skull. Dural metastasis was diagnosed and he received whole brain irradiation. In addition, laboratory examination revealed severe thrombocytopenia and leucopenia, and bone marrow study confirmed the diagnosis of metastatic squamous cell carcinoma. This is the first described case of esophageal squamous cell carcinoma with dural and bone marrow metastases. We also discuss the pathogenesis of unusual metastatic diseases and differential diagnosis of pachymeningeal thickening.

We report a rare case of a cervical spinal dural arteriovenous fistula(AVF)at the C2 level presenting with subarachnoid hemorrhage(SAH)due to a ruptured anterior spinal artery aneurysm. A 61-year-old man presented with sudden onset headache. Initial computed tomography revealed SAH around the brainstem. Digital subtraction angiography(DSA)demonstrated a cervical dural AVF that was fed by the left C1 radicular, left C2 radicular, and anterior spinal arteries, and drained into the epidural plexus. An aneurysm in the branch of the cervical anterior spinal artery was considered the bleeding point. A left lateral suboccipital craniotomy and C1 hemilaminectomy were performed on day 43. The feeding arteries were clipped, followed by coagulation of the draining veins. However, the aneurysm was not clipped because we deemed that obliteration of the aneurysm would be difficult without disrupting the blood flow of the parent artery. The patient showed no neurological deterioration after the operation. Postoperative DSA revealed residual dural AVF. Therefore, a second surgery was performed. After the second open surgery, DSA showed that the dural AVF and aneurysm disappeared. The patient also showed no neurological deterioration after the second surgery.

The objective of our study was to compare the incidence of blood patch as the best objective indicator of postdural puncture headache after elective fluoroscopic lumbar puncture with the use of a 22-gauge Whitacre (pencil point) needle versus standard 22- and 20-gauge Quincke (bevel-tip) needles and to determine the best level of puncture. The records of 724 consecutive patients who were referred to St. Mary's Medical Center department of radiology for fluoroscopic lumbar puncture from January 2003 through April 2007 were retrospectively reviewed. Emergency requests (191) were discarded along with those for patients with clinical signs of pseudotumor cerebri (21), normal pressure hydrocephalus (3), and failed attempts (4). The collective total was 505 elective lumbar punctures. The blood patch rate for the 22-gauge Whitacre needle was 4.2%. The result for the 22-gauge Quincke point needle was 15.1% whereas that for the 20-gauge Quincke point needle was 29.6%. In addition, the level of puncture showed a blood patch rate that increased as the level of lumbar puncture lowered. The highest level of lumbar puncture was L1-L2 with the lowest recorded level being L5-S1. The Whitacre needle is associated with a significantly lower incidence of blood patch rate after lumbar puncture. The highest level of puncture (L1-L2) also provides the lowest level of blood patch rate.

Update on New Daily Persistent Headache.

PubMed

Nierenburg, Hida; Newman, Lawrence C

2016-06-01

New daily persistent headache (NDPH) is an uncommon and under-recognized primary headache disorder. Clinically, NDPH may resemble migraine or tension-type headache. Unlike migraine or tension-type headaches, however, a distinguishing feature of NDPH is that the majority of patients with NDPH can pinpoint the exact date of onset of symptoms. While cases can arise de novo, in multiple reports, a viral illness precedes the onset of headache. NDPH has two temporal profiles: a self-limited form that resolves spontaneously without treatment and a refractory, persistent form in which headaches continue unabated for years. Diagnosis is predicated on first eliminating secondary mimics via diagnostic imaging and hematological studies. Lumbar puncture should be considered in patients who are refractory to treatment to search for alterations in CSF pressure or for an infectious process. There have been no randomized clinical trials utilizing acute or preventive therapies for NDPH. In clinical practice, treatment is aimed at matching the predominant headache phenotype; nonetheless, most therapies are generally ineffective or only partially effective. Not surprisingly, medication overuse is very common among patients with this disorder and should be identified, although in most patients, eliminating medication overuse does not alter the course of the illness. There have been reports of successful treatment combining doxycycline 100 mg and montelukast 10 mg, dosed BID for 3 months. Anecdotally, in our practice, this combination has occasionally provided good results. Onabotulinum toxin injections are currently under investigation and may provide a potential new effective treatment regimen.

Postdural puncture headache: a randomized prospective comparison of the 24 gauge Sprotte and the 27 gauge Quincke needles in young patients.

This study was designed to compare the frequency of postdural puncture headaches (PDPH) using the 24 gauge Sprotte and the 27 gauge Quincke spinal needles in a population of patients less than 45 yr of age undergoing spinal anaesthesia for non-obstetrical surgery. Patients were randomly assigned to receive spinal anaesthesia with either the 24 gauge Sprotte spinal needle (n = 46) or the 27 gauge Quincke spinal needle (n = 47). Patients were interviewed on either postoperative day one or two and on postoperative day three. A PDPH was defined as a headache involving the occipital or frontal areas that is made worse when assuming either the sitting or standing position. Ninety-three patients were included in the analysis of data. The overall incidence of PDPH was 14% (13 of 93), and no difference was found between the Sprotte (15.2%) and Quincke (12.8%) needles. The distribution of the PDPHs by severity was not different between the two groups. None of the 13 patients with PDPHs required on epidural blood patch for relief of symptoms. Both the Sprotte needle and the Quincke needles were judged as easy to use and both required the same number of attempts in order to locate cerebrospinal fluid (first attempt successful: 73.9% versus 66%). Neither patient satisfaction nor the acceptability of spinal anaesthesia for a future procedure was adversely affected by the occurrence of a PDPH. The results of this study suggest that the risk of PDPH after spinal anaesthesia in young patients is similar using either the 24 gauge Sprotte or the 27 gauge Quincke spinal needle.

To describe a case of intravitreal silicone oil (SO) migration into the cerebral ventricles with secondary chronic headaches. Retrospective case report. Chart review. Single patient. A 51-year-old man with a history of proliferative diabetic retinopathy underwent surgery for traction retinal detachment using SO. Postoperatively, he developed elevated intraocular pressure, headaches, and a blind painful eye, which was enucleated. Neuroimaging revealed SO within the cerebral ventricles. Five years after the initial retinal detachment surgery, the patient developed chronic headaches. Lumbar puncture revealed an elevated opening pressure. The headaches were initially managed medically. A ventriculoperitoneal shunt was placed after the headaches persisted, which resulted in their complete resolution at 6 weeks after shunt placement. Ocular hypertension after intravitreal SO placement may play a role in SO intracranial migration. In the case presented, intraventricular SO was the apparent cause of elevated intracranial pressure and headaches. As all published cases of intraventricular SO migration reporting intraocular pressure to this point have described ocular hypertension, careful monitoring of intraocular pressure and aggressive control of ocular hypertension in the presence of intravitreal SO is recommended.

Superficial siderosis (SS) of the CNS is a rare disease caused by repeated hemorrhages in the subarachnoid space. The subsequent deposition of hemosiderin in the brain and spinal cord leads to the progression of neurological deficits. The causes of bleeding include prior intradural surgery, carcinoma, arteriovenous malformation, nerve root avulsion, and dural abnormality. Recently, surgical treatment of SS associated with dural defect has been reported. The authors of the present report describe 2 surgically treated SS cases and review the literature on surgically treated SS. The patients had dural defects with fluid-filled collections in the spinal canal. In both cases, the dural defects were successfully closed, and the fluid collection was resolved postoperatively. In one case, the neurological symptoms did not progress postoperatively. In the other case, the patient had long history of SS, and the clinical manifestations partially deteriorated after surgery, despite the successful dural closure. In previously reported surgically treated cases, the dural defects were closed by sutures, patches, fibrin glue, or muscle/fat grafting. Regardless of the closing method, dural defect closure has been shown to stop CSF leakage and subarachnoid hemorrhaging. Successfully repairing the defect can halt the disease progression in most cases and may improve the symptoms that are associated with CSF hypovolemia. However, the effect of the dural closure may be limited in patients with long histories of SS because of the irreversibility of the neural tissue damage caused by hemosiderin deposition. In patients with SS, it is important to diagnose and repair the dural defect early to minimize the neurological impairments that are associated with dural defects.

Intracranial hypotension headache caused by a massive cerebrospinal fluid leak successfully treated with a targeted c2 epidural blood patch: a case report.

Cervical epidural steroid injections, administered either interlaminarly or transforaminally, are common injection therapies used in many interventional pain management practices to treat cervicalgia or cervicobrachial pain secondary to spondylosis or intervertebral disc displacement of the cervical spine. Among the risks associated with these procedures are the risk for inadvertent dural puncture and the development of positional headache from intracranial hypotension. We report the case of a 31-year-old woman with a history of migraine and cervicalgia from cervical spine spondylosis and cervical disc degenerative disease that developed an intractable orthostatic headache accompanied by nausea and vomiting after a therapeutic high cervical intralaminar epidural steroid injection was administered directly to the C1-C2 spinal level. Although the initial magnetic resonance imaging of the brain was unremarkable, a computed tomography myelogram study revealed a massive cerebrospinal fluid (CSF) leak from the cervical spine.  Repeated cervical epidural blood patches using a catheter targeted to the high cervical spine (C2) to inject 15 mL of autologous blood was required to totally alleviate her symptoms after she failed conservative therapy. Determining the optimal location or approach to administer an epidural blood patch can be a challenge depending on the location of the CSF leak. Our case demonstrates that targeted cervical epidural blood patch placement using an easily manipulated catheter under fluoroscopic guidance is a safe and effective approach to treat a massive CSF leak in the high cervical spine region caused by prior therapeutic cervical spine epidural steroid injection.

Postdural puncture backache (PDPB) is the most frequent complaint after spinal anesthesia. In the literature its importance is generally overshadowed by postdural puncture headache. We studied two different kinds of spinal anesthesia needles to compare their technical handling capacities and incidences of PDPB. Data of 256 pregnant female patients undergoing cesarean delivery under spinal anesthesia were collected for the study. Patients were divided into two groups as Group A (n = 109) and Group Q (n = 147) according to the spinal needle used for spinal anesthesia (i.e. 26-gauge atraumatic and 26-gauge Quincke needles, respectively). Backache incidences during a 1-week period postoperatively and handling characteristics of the needles were noted. Spinal anesthesia was successfully performed at one attempt in 92.7% and 86.4% of patients in Groups A and Q, respectively. PDPB was encountered in 62.4% and 44.2% of patients in Groups A and Q, respectively, and the difference was statistically significant (P = 0.037). Both 26-gauge Atraucan and Quincke needles have excellent handling characteristics. PDPB seems to be less common with the 26-gauge Quincke needle than with the Atraucan needle.

2014-01-01

We present a case of an incidental finding of dural ectasia in a child diagnosed with Larsen syndrome. Larsen syndrome is a rare inherited disorder of connective tissue characterized by facial dysmorphism, congenital joint dislocations of the hips, knees and elbows, and deformities of the hands and feet. Dural ectasia is as an abnormal expansion of the dural sac surrounding the spinal cord and may result in spinal morphologic changes, instability, and spontaneous dislocation. To the best of our knowledge, the presence of dural ectasia in Larsen syndrome has not previously been reported. A 6-year-old boy diagnosed with Larsen syndrome presented with an upper thoracic curve measuring 74 degrees, a right thoracic curve measuring 65 degrees, and significant cervicothoracic kyphosis with 50% anterior subluxation of C6 on C7 and C7 on T1. Advanced imaging studies showed dural ectasia (evidenced by spinal canal and dural sac expansion), thinning of pedicles and lamina, and C4 and C6 pars defects with cervical foramen enlargement. The patient received growing rod instrumentation (attached to cervical spine fixation) by a combined anterior/posterior surgical approach using intraoperative halo. Complications included intraoperative medial breach (fully resolved), wound dehiscence, 2 instances of bilateral broken rods, and a broken cervical rod. Following 7 lengthening procedures, the patient underwent definitive fusion. Surgeons should be aware of the potential for dural ectasia in patients with Larsen syndrome. Its presence will cause difficulties in the surgical intervention for spinal deformity. Multiple factors must be considered, and surgical approach and technique will require modification to avoid complications. Although dural ectasia confounds surgical intervention in these patients, surgery still appears to outweigh the risks associated with delayed intervention. The presence of dural ectasia should not preclude surgical decompression and stabilization. This report

The purpose of this article is to present a case series of transarterial venous sinus occlusion for dural arteriovenous fistulas (DAVFs) of the transverse and sigmoid sinuses. From 2006 to 2012, 11 patients with DAVF of the transverse and sigmoid sinuses were treated with transarterial closure of the affected venous sinus using ethylene vinyl alcohol copolymer (ONYX). The consecutive retrospective cohort included six female and five male patients with an age range of 30-79. Patients presented with stroke, intracranial hemorrhage, seizure, headache, focal neurologic deficit or cognitive change. Lesions were categorized as Cognard II a + b (n = 5) or Cognard II b (n = 6). Four of this latter group consisted of isolated sinus segments. Selection criteria for dural sinus occlusion included direct multi-hole fistulas involving a broad surface in length or circumference of the sinus wall. External carotid artery (ECA) branches were directly embolized when considered safe. High-risk arterial supply from ICA, PICA, AICA or ECA cranial nerve branches were closed via retrograde approach during sinus occlusion. DAVF closure was accomplished in all 11 patients with a total of 17 embolization procedures using ONYX. High-risk arterial collaterals were closed via artery-artery or artery-sinus-artery embolization. The vein of Labbe was spared in the four cases with initial antegrade flow. No neurologic complications occurred, and DAVF closures were durable on three-month angiography. Transarterial closure of the transverse and sigmoid sinuses. © The Author(s) 2016.

Though endovascular therapy (EVT) is increasingly applied in the treatment of intracranial vascular lesions, little is known about the effect of EVT on post-procedure headache. We aimed to investigate the prevalence of headache in patients who have undergone EVT for cerebral arteriovenous malformations (AVMs) and aneurysms. A total of 324 patients underwent EVT treatment for aneurysms and AVMs at the Danish National Hospital from January 2012 to December 2014. We applied strict exclusion criteria in order to minimize the effect of other factors on headache occurrence, e.g., craniotomy. Eligible subjects were phone-interviewed using a purpose-developed semi-structured questionnaire. Headaches were classified according to ICHD-III beta criteria. The 59 patients underwent treatment of aneurysms (n = 43), cranial dural fistulas (n = 11), and AVMs (n = 5). There was a significant increase in overall headache (p = 0.017) and tension-type headache (TTH) (p = 0.012) within the first 3 months after EVT compared to 1 month before EVT. However, at interview time (median 2.5 years post-EVT), the increase in overall headache, migraine, and tension-type headache was not statistically significant. A minority of patients experienced headaches for the first time within 3 months of their EVT (migraine 4, TTH 10). At interview time, 50 % of these new headaches still persisted. Our results suggest a temporary increase in headache in the first 3 months after EVT, which normalizes over time. Clinicians may use this knowledge to better inform their patients of functional outcomes after their EVT procedure.

Changes in cerebrospinal fluid (CSF) biomarkers are representative of biochemical changes in the brain. Collection of CSF by lumbar puncture (LP) is essential for biomarker analysis, which is important for research in neurodegenerative disorders. However, LP for research purposes has been controversial due to a reported high incidence of severe LP headache when using standard 18g or 20g Quincke needles with a beveled cutting tip. A procedural safety analysis was performed using the database of a multicenter, 13-week study of CSF cholinesterase activity. A 24g Sprotte atraumatic needle was used to collect CSF at baseline and at Week 13 from 63 older patients with mild to moderate Alzheimer's disease. There was a < 2% LP headache incidence, and a favorable safety profile was reported. In conclusion, LP performed with a 24g Sprotte atraumatic needle (blunt, “bullet” tip) was a well-tolerated procedure, with good acceptability. PMID:19519311

Cerebrospinal fluid leakage is an immanent risk of cranial surgery with dural opening. Recognizing the risk factors for this complication and improving the technique of dural closure may reduce the associated morbidity and its surgical burden. The aim of this paper was to investigate whether the addition of TachoSil on top of the dural suture reduces postoperative CSF leakage compared with dural suturing alone and to assess the frequency and risk factors for dural leakage and potentially related complications after elective craniotomy. The authors conducted a prospective, randomized, double-blinded single-center trial in patients undergoing elective craniotomy with dural opening. They compared their standard dural closure by running suture alone (with the use of a dural patch if needed) to the same closure with the addition of TachoSil on top of the suture. The primary end point was the incidence of CSF leakage, defined as CSF collection or any open CSF fistula within 30 days. Secondary end points were the incidence of infection, surgical revision, and length of stay in the intensive care unit (ICU) or intermediate care (IMC) unit. The site of craniotomy, a history of diabetes mellitus, a diagnosis of meningioma, the intraoperative need of a suturable dural substitute, and blood parameters were assessed as potential risk factors for CSF leakage. The authors enrolled 241 patients, of whom 229 were included in the analysis. Cerebrospinal fluid leakage, mostly self-limiting subgaleal collections, occurred in 13.5% of patients. Invasive treatment was performed in 8 patients (3.5%) (subgaleal puncture in 6, lumbar drainage in 1, and surgical revision in 1 patient). Diabetes mellitus, a higher preoperative level of C-reactive protein (CRP), and the intraoperative need for a dural patch were positively associated with the occurrence of the primary end point (p = 0.014, 0.01, and 0.049, respectively).

Various in vitro models have been introduced for comparative examinations of post-dural-puncture trauma and measurement of liquor leakage through puncture sites. These models allow simulation of subarachnoid, but not of peridural, pressure. A new two-chamber-model realizes the simulation of both subarachnoid and peridural pressure and allows observation of in vitro punctures with video-documentation. Frame grabbing and (computer-aided) image analysis show new aspects of spinal puncture effects. Therefore, post-dural-puncture trauma and retraction can be objectively visualized by this method, which has not previously been demonstrated. Two-chamber-model consists of two short aluminium cylinders. Native human dura patches (8X8 mm) from fresh cadavers are put (correctly oriented) between two special polyamide seals. Mounted between the upper and lower cylinder, these seals stretch the dura patch, which remains flexible and even in all directions. After filling of the lower (subarachnoid) and upper (peridural) chamber with Ringer lactate solution, positive or negative physiological pressure can be adjusted by way of two (Ringer lactate solution filled) infusion lines in each chamber. Puncturing is performed at an angle of 57 degrees to the dura. The model allows examination with epi-illumination and transmitted (polarized) light. In vitro punctures are observed through an inverted camera lens with an CCD-Hi8 video camera (Canon UC1HI) looking into the peridural chamber and documented by means of an S-VHS video recorder (Panasonic NV-FS200EG). After true-colour frame grabbing by a video digitizer (Fast Screen Machine II), single video frames can be optimized and analysed with a 486-66 MHz computer and conventional software (Corel Draw 3.0, Photostyler 1.1a, DDL Aequitas 1.00b). Punctures demonstrated in this paper have been done under simulation of a transdural gradient of 20 cm water similar to the situation of a recumbent patient (15 cm water in the subarachnoid and

An intraosseous dural arteriovenous fistula (DAVF) is a rare cerebrovascular disease. The fistulous connection occurs within intraosseous diploic or transosseous emissary veins causing dilated intraosseous vascular pouches. To the authors' knowledge, this report describes the first percutaneous transfacial direct embolization of an intraosseous DAVF. A man in his 50s with blue rubber bleb nevus syndrome presented with headaches, imbalance, decreased visual acuity bilaterally, and left eye proptosis and chemosis. Imaging demonstrated an extensive intraosseous DAVF with dilated intraosseous vascular pouches throughout his cranial base and intraorbital venous congestion. He underwent staged endovascular treatment with the goal to improve his ocular symptoms. Transarterial and transvenous approaches failed to provide adequate access to the intraosseous vascular pouches. A direct, percutaneous transfacial approach was used to access the pouches for embolization with coils and liquid embolic material. Postoperative angiography demonstrated successful embolization of the pouch within the left pterygoid wing, reduced opacification of the intraosseous fistula, and elimination of intraorbital venous congestion. At 9-month follow-up, the patient's headaches had resolved, and his ocular symptomatology had improved. Endovascular access to an intraosseous DAVF is limited by the size and location of the intraosseous vascular pouches. In this case, a direct transfacial approach under image guidance facilitated access and embolization, which led to an improvement in the patient's symptoms. This technique is a novel approach for DAVF management.

Duraplasty, a common neurosurgical intervention, involves synthetic or biological graft placement to ensure dural closure. The objective of this study is to advance our understanding of the use of dural substitutes in cranial surgery. The PubMed database was systematically searched to identify studies published over the past decade (2007-2017) that described duraplasty procedures. Clinical data were disaggregated and analyzed for the comparisons of biological versus synthetic grafts. A total of 462 cases were included in the quantitative synthesis. Overall, the most common indication for duraplasty was tumor resection (53%). Allografts were more frequently used in decompression for Chiari malformations compared with xenografts and synthetic grafts (P < 0.001). Xenografts were more frequently used in decompressive hemicraniectomy procedures for evacuation of acute subdural hematomas over allografts and synthetics (P < 0.001). Synthetic grafts were more frequently used in tumor cases than biological grafts (P = 0.002). The cumulative complication rate for dural substitutes of all types was 11%. There were no significant differences in complication rates among the 3 types of dural substitutes. Dural substitutes are commonly used to ensure dural closure in a variety of cranial procedures. This study provides greater insight into duraplasty practices and highlights the moderate complication rate associated with the procedure. Future studies are needed to determine the safety and efficacy of such procedures in larger prospective cohorts. Copyright © 2018. Published by Elsevier Inc.

Animal models are essential for studying the pathophysiology of headache disorders and as a screening tool for new therapies. Most animal models modify a normal animal in an attempt to mimic migraine symptoms. They require manipulation to activate the trigeminal nerve or dural nociceptors. At best, they are models of secondary headache. No existing model can address the fundamental question: How is a primary headache spontaneously initiated? In the process of obtaining baseline periorbital von Frey thresholds in a wild-type Sprague-Dawley rat, we discovered a rat with spontaneous episodic trigeminal allodynia (manifested by episodically changing periorbital pain threshold). Subsequent mating showed that the trait is inherited. Animals with spontaneous trigeminal allodynia allow us to study the pathophysiology of primary recurrent headache disorders. To validate this as a model for migraine, we tested the effects of clinically proven acute and preventive migraine treatments on spontaneous changes in rat periorbital sensitivity. Sumatriptan, ketorolac, and dihydroergotamine temporarily reversed the low periorbital pain thresholds. Thirty days of chronic valproic acid treatment prevented spontaneous changes in trigeminal allodynia. After discontinuation, the rats returned to their baseline of spontaneous episodic threshold changes. We also tested the effects of known chemical human migraine triggers. On days when the rats did not have allodynia and showed normal periorbital von Frey thresholds, glycerol trinitrate and calcitonin gene related peptide induced significant decreases in the periorbital pain threshold. This model can be used as a predictive model for drug development and for studies of putative biomarkers for headache diagnosis and treatment. PMID:22963523

During migraine, trigeminal nerves may release calcitonin gene-related peptide (CGRP), inducing cranial vasodilatation and central nociception; hence, trigeminal inhibition or blockade of craniovascular CGRP receptors may prevent this vasodilatation and abort migraine headache. Several preclinical studies have shown that glutamate receptor antagonists affect the pathophysiology of migraine. This study investigated whether antagonists of NMDA (ketamine and MK801), AMPA (GYKI52466) and kainate (LY466195) glutamate receptors affected dural vasodilatation induced by alpha-CGRP, capsaicin and periarterial electrical stimulation in rats, using intravital microscopy. Male Sprague-Dawley rats were anaesthetized and the overlying bone was thinned to visualize the dural artery. Then, vasodilator responses to exogenous (i.v. alpha-CGRP) and endogenous (released by i.v. capsaicin and periarterial electrical stimulation) CGRP were elicited in the absence or presence of the above antagonists. alpha-CGRP, capsaicin and periarterial electrical stimulation increased dural artery diameter. Ketamine and MK801 inhibited the vasodilator responses to capsaicin and electrical stimulation, while only ketamine attenuated those to alpha-CGRP. In contrast, GYKI52466 only attenuated the vasodilatation to exogenous alpha-CGRP, while LY466195 did not affect the vasodilator responses to endogenous or exogenous CGRP. Although GYKI52466 has not been tested clinically, our data suggest that it would not inhibit migraine via vascular mechanisms. Similarly, the antimigraine efficacy of LY466195 seems unrelated to vascular CGRP-mediated pathways and/or receptors. In contrast, the cranial vascular effects of ketamine and MK801 may represent a therapeutic mechanism, although the same mechanism might contribute, peripherally, to cardiovascular side effects.

We here report a 13-year-old Marfan patient who suffered from severe, medication-resistant, intermittent headache, which was provoked when getting into an upright position and immediately relieved by lying down or after intravenous rehydration. The postural benefit and the sudden relief after intravenous hydration suggested (intermittent) intracranial hypotension, although a normal opening pressure on lumbar punction was observed and no cerebrospinal fluid (CSF) leakage was identified. Imaging studies revealed severe dural ectasia at lumbosacral level, and two intradural cysts and two extradural presacral cysts were detected. Most likely, altered hydrodynamics in intra- and extracranial spinal meningeal cysts caused intermittent CSF hypotension above these cysts, resulting in intermittent intracranial hypotension. Surgical marsupialisation of the intradural cysts proved to be effective. This resulted in a significant reduction of the headache during the clinical follow-up of eight years.

The aim of the study is to report our first impressions about Adherus, a novel dural sealant, used in neurosurgical endoscopic transnasal procedures. We retrospectively reviewed the clinical and surgical records of the first 11 patients with intraoperative high-flow cerebrospinal fluid leak treated with the aid of Adherus at our center between February and October 2014. The healing at the level of the dural plasty was monitored and evaluated radiologically and with regular endoscopic inspections. With a median follow-up of 210 days, no postoperative CSF leak or surgical site infections were found in any of the cases. Based on our preliminary experience, this new dural sealant seems to provide an effective aid in dural plasty during endoscopic transphenoidal procedures.

In this study, we evaluated the effect of dexamethasone used as a prophylaxis for nausea and vomiting on the incidence of postdural puncture headache (PDPH) in pregnant women receiving spinal anesthesia for cesarean section. In a prospective, randomized, double-blind, placebo-controlled study, 372 women under spinal anesthesia received 8 mg of dexamethasone or placebo intravenously just after the umbilical cord was clamped. The rate of PDPH and correlated risk factors were evaluated. The prevalence of nausea and vomiting in the dexamethasone and placebo groups was 54.4 and 51.7%, respectively. There was no statistically meaningful difference between the results (P value = 0.673). The overall incidence rate of PDPH was 10.8%, with 28 cases from the dexamethasone group compared with 11 subjects from the placebo group (P value = 0.006). This effect was most prominent on the first day (P value = 0.046) and disappeared on the second day after spinal anesthesia (P value = 0.678). Prophylactic treatment with 8 mg of dexamethasone not only increases the severity and incidence of PDPH, but is also ineffective in decreasing the prevalence of intra-operative nausea and vomiting during cesarean section. The treatment is a significant risk factor for the development of PDPH.

Postoperative cerebrospinal fluid (CSF) leaks and headaches remain potential complications after retrosigmoid approaches for lesions in the posterior fossa and cerebellopontine angle. The authors describe a simple repair technique with an autologous fat graft-assisted Medpor Titan cranioplasty and investigate the incidence of postoperative CSF leaks and headaches using this technique. A retrospective chart review was conducted on all cases (n = 60) of retrosigmoid craniectomy from September 2009 to May 2014 in patients who underwent fat graft-assisted cranioplasty. After obtaining a watertight dural closure and sealing off any visible mastoid air cells with bone wax, an autologous fat graft was placed over the dural suture line and up against the waxed-off air cells. The fat graft filled the retrosigmoid cranial defect and was then bolstered with a Medpor Titan (titanium mesh embedded in porous polyethylene) cranioplasty. A postoperative mastoid pressure dressing was applied for 48 h, and prophylactic lumbar drainage was not used. Factors examined in this study included postoperative CSF leak (incisional, rhinorrhea, otorrhea), pseudomeningocele formation, incidence and severity of postoperative headache, length of hospital stay, and length of follow-up. No patients developed postoperative CSF leaks (0 %), pseudomeningoceles (0 %), or new-onset postoperative headaches (0 %) with the described repair technique. There were no cases of graft site morbidity such as hematoma or wound infection. Mean duration of postoperative hospital stay was 3.8 days (range 2-10 days). Mean postoperative follow-up was 12.4 months (range 2.0-41.1 months). Our multilayer repair technique with a fat graft-assisted Medpor Titan cranioplasty appears effective in preventing postoperative CSF leaks and new-onset postoperative headaches after retrosigmoid approaches. Postoperative lumbar drainage may not be necessary.

Sudden headache, third nerve palsy and visual deficit: thinking outside the subarachnoid haemorrhage box.

A 75-year-old lady presented with sudden severe headache and vomiting. Examination was normal, and CT and lumbar puncture not convincing for subarachnoid haemorrhage. Shortly thereafter, she developed painless diplopia. Examination confirmed right third cranial nerve palsy plus homonymous left inferior quadrantanopia. Urgent cerebral MRI with angiography was requested to assess for a possible posterior communicating artery aneurysm, but revealed an unsuspected pituitary mass. Pituitary adenoma with pituitary apoplexy was diagnosed. Pituitary apopolexy is a syndrome comprising sudden headache, meningism, visual and/or oculomotor deficits, with an intrasellar mass. It is commonly due to haemorrhage or infarction within a pituitary adenoma. Treatment includes prompt steroid administration, and potentially surgical decompression. While subarachnoid haemorrhage is an important, well-recognised cause of sudden severe headache, other aetiologies, including pituitary apoplexy, should be considered and sought.

Needle biopsy is a method to extract the cells from the patient's body with a needle for tissue pathological examination. Many factors affect the cutting process of soft tissue, including the geometry of the biopsy needle, the mechanical properties of the soft tissue, the parameters of the puncture process and the interaction between them. This paper conducted orthogonal experiment of main cutting parameters based on single plane puncture biopsy needle, and obtained the cutting force curve of single plane puncture biopsy needle by studying the influence of the inclination angle, diameter and velocity of the single plane puncture biopsy needle on the puncture force of the biopsy needle. Stage analysis of the cutting process of biopsy needle puncture was made to determine the main influencing factors of puncture force during the cutting process, which provides a certain theoretical support for the design of new type of puncture biopsy needle and the operation of puncture biopsy.

Oblique lumbar interbody fusion (OLIF) through the oblique corridor between the aorta and anterior border of psoas muscle is favored among spinal surgeons who employ minimally invasive techniques. We report a case of ventral dural tear after OLIF that was associated with the inaccurate trajectory direction of endplate preparation. This is the first report to our knowledge of ventral dural tear associated with OLIF. A 72-year-old woman presented with right leg pain and numbness. X-rays showed degenerative spondylolisthesis and loss of disc height at L4-L5 and L5-S1 levels. Magnetic resonance imaging revealed right-sided paracentral disc herniation at the L3-L4 level and foraminal disc herniation at L4-L5. The initial surgical plan was OLIF of L3-L4 and L4-L5 after percutaneous screw fixation without laminectomy. With the patient in the lateral position, discectomy and endplate preparation were done successfully at the L3-L4 level, and the same procedure was done at the L4-L5 level for OLIF. A sharp Cobbs elevator for endplate preparation triggered a ventral dural defect at the L4-L5 level. We changed the patient's position to attempt dural repair. The ventral dural defect could not be repaired because it was too large. After the herniated rootlets were repositioned, TachoComb was patched over the defect site. Postoperatively, the patient has no definite neurologic deficits. When a surgeon performs OLIF, ventral dural injury should be avoided during the procedure of endplate preparation and contralateral annular release. Copyright © 2016 Elsevier Inc.

Marfan syndrome is an autosomal dominant disorder of connective tissue caused by mutations in the gene encoding fibrillin-1 (FBN1), a matrix component of microfibrils. Dural ectasia, i.e. enlargement of the neural canal mainly located in the lower lumbar and sacral region, frequently occurs in Marfan patients. The aim of our study was to investigate the role of dural ectasia in raising the diagnosis of Marfan syndrome and its association with FBN1 mutations. We studied 40 unrelated patients suspected for MFS, who underwent magnetic resonance imaging searching for dural ectasia. In all of them FBN1 gene analysis was also performed. Thirty-seven patients resulted affected by Marfan syndrome according to the '96 Ghent criteria; in 30 of them the diagnosis was confirmed when revaluated by the recently revised criteria (2010). Thirty-six patients resulted positive for dural ectasia. The degree of dural ectasia was grade 1 in 19 patients, grade 2 in 11 patients, and grade 3 in 6 patients. In 7 (24%) patients, the presence of dural ectasia allowed to reach a positive score for systemic feature criterion. Twenty-four patients carried an FBN1 mutation, that were represented by 13 missense (54%), and 11 (46%) mutations generating a premature termination codon (PTC, frameshifts and stop codons). No mutation was detected in the remaining 16 (6 patients with MFS and 10 with related disorders according to revised Ghent criteria). The prevalence of severe (grade 2 and grade 3) involvement of dura mater was higher in patients harbouring premature termination codon (PTC) mutations than those carrying missense-mutations (8/11 vs 2/13, P = 0.0111). Our data emphasizes the importance of dural ectasia screening to reach the diagnosis of Marfan syndrome especially when it is uncertain and indicates an association between PTC mutations and severe dural ectasia in Marfan patients.

Headache is a common complaint in children occasionally requiring hospital admission. The purposes of the present study were to analyze the prevalence of uncorrected ametropia in children with headache admitted to the hospital, and evaluate the importance of refraction assessment as part of their evaluation. A retrospective review of children admitted to the Tel Aviv Medical Center for headache evaluation from December 2008 to March 2013, in whom the only abnormality found was an uncorrected refractive error. During the study period 917 children with headache were hospitalized for evaluation and 16 (1.7%) of them (9 boys, mean age 12 years, range 8-18 years) were found to have an uncorrected ametropia. Average headache duration was 4 months (range, 1 week to 1 year) and mean follow-up was 15 months (range, 1 month to 3 years). Twelve (75%) children had brain imaging and 4 children (25%) had a lumbar puncture before their refractive abnormality was identified. Anisometropia and myopia were the most common refractive errors encountered (n = 10 each), followed by hyperopia (n = 6) and astigmatism (n = 3). Despite having uncorrected refractive errors most children (n = 10) did not complain of any visual difficulty. All children were given proper refractive correction and 14 of them reported complete headache resolution on re-examination one month later. Uncorrected ametropia is a possible cause of headache among hospitalized children. Therefore, complete ophthalmic evaluation, which includes proper refraction assessment, is important as it can identify a treatable headache etiology. Children without visual difficulty should be equally evaluated, as many children with headache and uncorrected amteropia do not have vision complaints.

The trigeminovascular system within the cranial dura mater is a possible cause of headaches. The aim of this study is to investigate macroscopically dural innervation around the middle meningeal artery (MMA) in the middle cranial fossa. Forty-four sides of the cranial dura overlying the skull base obtained from 24 human cadavers were stained using Sihler’s method. Overall, the nervus spinosus (NS) from either the maxillary or mandibular trigeminal divisions ran along the lateral wall of the middle meningeal vein rather than that of the MMA. Distinct bundles of the NS running along the course of the frontal branches of the MMA were present in 81.8% of cases (N = 36). Others did not form dominant nerve bundles, instead giving off free nerve endings along the course of the MMA or dural connective tissue. The distribution of these nerve endings was similar to that of the course of the frontal, parietal and petrosal branches of the MMA (11.4%). The others were not restricted to a perivascular plexus, crossing the dural connective tissues far from the MMA (6.8%). These findings indicate that the NS generally travels alongside the course of the frontal branches of the MMA and terminates in the vicinity of the pterion. PMID:29311855

A source of bleeding is often not evident during the evaluation of patients with superficial siderosis of the CNS despite extensive imaging. An intraspinal fluid-filled collection of variable dimensions is frequently observed on spine MR imaging in patients with idiopathic superficial siderosis. A similar finding has also been reported in patients with idiopathic intracranial hypotension. The authors report on a patient with superficial siderosis and a longitudinally extensive intraspinal fluid-filled collection secondary to a dural tear. The patient had a history of low-pressure headaches. His spine MR imaging and spine CT suggested the possibility of an underlying vascular malformation, but none was found on angiography. Repair of the dural tear resulted in resolution of the intraspinal fluid collection and CSF abnormalities. The significance of the association between superficial siderosis and idiopathic intracranial hypotension, and potential therapeutic and pathophysiological implications, are the subject of this report.

The clinical significance of pathologies of the spinal dura is often unclear and their management controversial. To classify spinal dural pathologies analogous to vascular aneurysms, present their symptoms and surgical results. Among 1519 patients with spinal space-occupying lesions, 66 patients demonstrated dural pathologies. Neuroradiological and surgical features were reviewed and clinical data analyzed. Saccular dural diverticula (type I, n = 28) caused by defects of both dural layers, dissections between dural layers (type II, n = 29) due to defects of the inner layer, and dural ectasias (type III, n = 9) related to structural changes of the dura were distinguished. For all types, symptoms consisted of local pain followed by signs of radiculopathy or myelopathy, while one patient with dural ectasia presented a low-pressure syndrome and 10 patients with dural dissections additional spinal cord herniation. Type I and type II pathologies required occlusion of their dural defects via extradural (type I) or intradural (type II) approaches. For type III pathologies of the dural sac no surgery was recommended. Favorable results were obtained in all 14 patients with type I and 13 of 15 patients with type II pathologies undergoing surgery. The majority of dural pathologies involving root sleeves remain asymptomatic, while those of the dural sac commonly lead to pain and neurological symptoms. Type I and type II pathologies were treated with good long-term results occluding their dural defects, while ectasias of the dural sac (type III) were managed conservatively.

Detailed descriptions of stepwise dural opening/removal for combined petrosal approach are presented. Following maximum bone work, the first dural incision was made along the undersurface of the temporal lobe parallel to the superior petrosal sinus. Posterior extension of the dural incision was made in a curved fashion, keeping away from the transverse-sigmoid junction and taking care to preserve the vein of Labbé. A second incision was made perpendicular to the first incision. After sectioning the superior petrosal sinus around the porus trigeminus, the incision was extended toward the posterior fossa dura in the middle fossa region. The tentorium was incised toward the incisura at a point just posterior to the entrance of the trochlear nerve. A third incision was made longitudinally between the superior petrosal sinus and the jugular bulb. A final incision was initiated perpendicular to the third incision in the presigmoid region and extended parallel to the superior petrosal sinus connecting the second incision. The dural complex consisting of the temporal lobe dura, the posterior fossa dura, and the freed tentorium could then be removed. In addition to extensive bone resection, our strategic cranial base dural opening/removal can yield true advantages for the combined petrosal approach.

Migraine is a paroxysmal, disabling primary headache that affects 16 % of the adult population. In spite of decades of intense research, the origin and the pathophysiology mechanisms involved are still not fully known. Although triptans and gepants provide effective relief from acute migraine for many patients, their site of action remains unidentified. It has been suggested that during migraine attacks the leakiness of the blood-brain barrier (BBB) is altered, increasing the passage of anti-migraine drugs. This study aimed to investigate the effect of experimental inflammation, following dural application of complete Freund's adjuvant (CFA) or inflammatory soup (IS) on brain and trigeminal microvascular passage. In order to address this issue, we induced local inflammation in male Sprague-Dawley-rats dura mater by the addition of CFA or IS directly on the dural surface. Following 2, 24 or 48 h of inflammation we calculated permeability-surface area product (PS) for [(51)Cr]-EDTA in the trigeminal ganglion (TG), spinal trigeminal nucleus, cortex, periaqueductal grey and cerebellum. We observed that [(51)Cr]-EDTA did not pass into the central nervous system (CNS) in a major way. However, [(51)Cr]-EDTA readily passed the TG by >30 times compared to the CNS. Application of CFA or IS did not show altered transfer constants. With these experiments we show that dural IS/CFA triggered TG inflammation, did not increase the BBB passage, and that the TG is readily exposed to circulating molecules. The TG could provide a site of anti-migraine drug interaction with effect on the trigeminal system.

Use of a 22-gauge Whitacre needle to reduce the incidence of side effects after lumbar myelography: a prospective randomised study comparing Whitacre and Quincke spinal needles.

Pedersen, O N

1996-01-01

In a prospective study lumbar iohexol myelography was performed in 107 consecutive patients, randomised for lumbar puncture with a Quincke or Whitacre spinal needle. All patients answered a questionnaire about possible side effects. Data from 100 patients (58 men, 42 women) were evaluated. In the Quincke group (n = 53), 23 (43%) reported no side effects. In the 30 patients who reported various side effects, post-dural puncture headache (PDPH) occurred in 22 (42%), of whom 9 had mild, 6 moderate and 7 (13%) severe cephalalgia, 18 (34%) reported increased low back pain/sciatica, 5 nausea and 7 dizziness. In the Whitacre group (n = 47), 33 (70%) had no side effects. PDPH was reported by 9 patients (19%), of whom 2 had mild, 6 moderate and only 1 (2%) severe cephalalgia, 4 (9%) reported increased low back pain/sciatica, 5 nausea and 4 dizziness. The conclusion drawn from this study is that lumbar myelography performed with the Whitacre spinal needle reduces postspinal side effects.

To characterize the phenotype, headache-related disability, medical co-morbidities, use of symptomatic headache medications, and headache response to study interventions in the Idiopathic Intracranial Hypertension Treatment Trial (IIHTT). Patients with untreated IIH and mild vision loss enrolled in the IIHTT and randomized to acetazolamide (ACZ) and weight loss or placebo (PLB) and weight loss had prospective assessment of headache disability using the Headache Impact Test-6 (HIT-6) questionnaire. Subjects with headache at the baseline visit were assigned a headache phenotype using the International Classification for Headache Disorders version 3 beta (ICHD-3b). Medication overuse was determined using the participants' reported medication use for the preceding month and ICHD-3b thresholds for diagnosing medication overuse headache. We investigated relationships between headache disability and various other clinical characteristics at baseline and at 6 months. Headache was present in 139 (84%) of the 165 enrollees at baseline. The most common headache phenotypes were migraine (52%), tension-type headache (22%), probable migraine (16%), and probable tension-type headache (4%). Fifty-one (37%) participants overused symptomatic medications at baseline, most frequently simple analgesics. A similar amount of improvement in the adjusted mean (± standard error) HIT-6 score occurred in the ACZ (-9.56 ± 1.05) and PLB groups (-9.11 ± 1.14) at 6 months (group difference -0.45, 95% CI -3.50 to 2.60, P = .77). Headache disability did not correlate with any of the studies, variables of interest, which included: the lumbar puncture opening pressure at baseline or at 6 months, body mass index, the amount of weight lost, papilledema grade, perimetric mean deviation, or the use of hormonal contraception. Headache disability was significantly associated with patient-reported quality of life in the physical, mental, and visual domains. Headache was common, of varied

Compound depressed skull fracture (DSF) is a neurosurgical emergency. Preoperative knowledge of dural status is indispensable for treatment decision making. This study aimed to determine predictors of dural tear from clinical and imaging characteristics in patients with compound DSF. This prospective, multicenter correlational study in neurosurgical hospitals in Addis Ababa, Ethiopia, included 128 patients operated on from January 1, 2016, to October 31, 2016. Clinical, imaging, and intraoperative findings were evaluated. Univariate and multivariate analyses were used to establish predictors of dural tear. A logistic regression model was developed to predict probability of dural tear. Model validation was done using the receiver operating characteristic curve. Dural tear was seen in 55.5% of 128 patients. Demographics, injury mechanism, clinical presentation, and site of DSF had no significant correlation with dural tear. In univariate and multivariate analyses, depth of fracture depression (odds ratio 1.3, P < 0.001), pneumocephalus (odds ratio 2.8, P = 0.005), and brain contusions/intracerebral hematoma (odds ratio 5.5, P < 0.001) were significantly correlated with dural tear. We developed a logistic regression model (diagnostic test) to calculate probability of dural tear. Using the receiver operating characteristic curve, we determined the cutoff value for a positive test giving the highest accuracy to be 30% with a corresponding sensitivity of 93.0% and specificity of 43.9%. Dural tear in compound DSF can be predicted with 93.0% sensitivity using preoperative findings and may guide treatment decision making in resource-limited settings where risk of extensive cranial surgery outweighs the benefit.

Retrospective multicenter case series study. Because cervical dural tears are rare, most surgeons have limited experience with this complication. A multicenter study was performed to better understand the presentation, treatment, and outcomes following cervical dural tears. Multiple surgeons from 23 institutions retrospectively identified 21 rare complications that occurred between 2005 and 2011, including unintentional cervical dural tears. Demographic data and surgical history were obtained. Clinical outcomes following surgery were assessed, and any reoperations were recorded. Neck Disability Index (NDI), modified Japanese Orthopaedic Association (mJOA), Nurick classification (NuC), and Short-Form 36 (SF36) scores were recorded at baseline and final follow-up at certain centers. All data were collected, collated, and analyzed by a private research organization. There were 109 cases of cervical dural tears among 18 463 surgeries performed. In 101 cases (93%) there was no clinical sequelae following successful dural tear repair. There were statistical improvements ( P < .05) in mJOA and NuC scores, but not NDI or SF36 scores. No specific baseline or operative factors were found to be associated with the occurrence of dural tears. In most cases, no further postoperative treatments of the dural tear were required, while there were 13 patients (12%) that required subsequent treatment of cerebrospinal fluid drainage. Analysis of those requiring further treatments did not identify an optimum treatment strategy for cervical dural tears. In this multicenter study, we report our findings on the largest reported series (n = 109) of cervical dural tears. In a vast majority of cases, no subsequent interventions were required and no clinical sequelae were observed.

Puncture wounds of the foot are a common injury, and infection associated with these injuries may result in considerable morbidity. The pathophysiology and management of a puncture wound is dependent on the material that punctures the foot, the location and depth of the wound, time to presentation, footwear, and underlying health status of the patient. Puncture wounds should not be treated lightly, so accurate diagnosis, assessment, and treatment are paramount. Early incision and drainage, vaccination, and the use of proper antibiotics can lead to positive outcomes and prevent limb-threatening circumstances. Copyright © 2012 Elsevier Inc.

Expression of the transient receptor potential channels TRPV1, TRPA1 and TRPM8 in mouse trigeminal primary afferent neurons innervating the dura

PubMed Central

2012-01-01

Background Migraine and other headache disorders affect a large percentage of the population and cause debilitating pain. Activation and sensitization of the trigeminal primary afferent neurons innervating the dura and cerebral vessels is a crucial step in the “headache circuit”. Many dural afferent neurons respond to algesic and inflammatory agents. Given the clear role of the transient receptor potential (TRP) family of channels in both sensing chemical stimulants and mediating inflammatory pain, we investigated the expression of TRP channels in dural afferent neurons. Methods We used two fluorescent tracers to retrogradely label dural afferent neurons in adult mice and quantified the abundance of peptidergic and non-peptidergic neuron populations using calcitonin gene-related peptide immunoreactivity (CGRP-ir) and isolectin B4 (IB4) binding as markers, respectively. Using immunohistochemistry, we compared the expression of TRPV1 and TRPA1 channels in dural afferent neurons with the expression in total trigeminal ganglion (TG) neurons. To examine the distribution of TRPM8 channels, we labeled dural afferent neurons in mice expressing farnesylated enhanced green fluorescent protein (EGFPf) from a TRPM8 locus. We used nearest-neighbor measurement to predict the spatial association between dural afferent neurons and neurons expressing TRPA1 or TRPM8 channels in the TG. Results and conclusions We report that the size of dural afferent neurons is significantly larger than that of total TG neurons and facial skin afferents. Approximately 40% of dural afferent neurons exhibit IB4 binding. Surprisingly, the percentage of dural afferent neurons containing CGRP-ir is significantly lower than those of total TG neurons and facial skin afferents. Both TRPV1 and TRPA1 channels are expressed in dural afferent neurons. Furthermore, nearest-neighbor measurement indicates that TRPA1-expressing neurons are clustered around a subset of dural afferent neurons. Interestingly, TRPM

Monosodium glutamate alters the response properties of rat trigeminovascular neurons through activation of peripheral NMDA receptors.

Ingestion of monosodium glutamate (MSG) has been shown to cause headaches in healthy individuals and trigger migraine-like headaches in migraine sufferers. We combined immunohistochemistry, in vivo electrophysiology, and laser Doppler recordings of dural vasculature to investigate the effect of systemic administration of MSG on the trigeminovascular pathway. Immunohistochemical analysis confirmed the expression of NMDA receptors on nerve fibers innervating dural blood vessels and excitatory amino acid transporter 2 on dural blood vessels. Systemic administration of MSG (50mg/kg) evoked an increase in ongoing discharge in 5/6 spinal trigeminal subnucleus caudalis (SpVc) neurons with dural input recorded from male and female rats, respectively, as well as lowering their mechanical activation threshold. There were no sex-related differences in these effects of MSG. Neuronal discharge and mechanical sensitization were significantly attenuated by co-injection with the peripherally restricted NMDA receptor antagonist (2R)-amino-5-phosphonovaleric acid (APV) in both sexes. Systemic administration of MSG induced a 24.5% and 20.6% increase in dural flux in male and female rats, respectively. These results suggest that MSG-induced headache is mediated by the activation of peripheral NMDA receptors and subsequent dural vasodilation. Peripheral NMDA receptors are a potential target for the development of new drugs to treat headaches. Copyright © 2016 IBRO. Published by Elsevier Ltd. All rights reserved.

Summary Onyx migration in the endovascular treatment of dural arteriovenous fistulas (dural AVFs) is uncommon. We describe five cases of Onyx migration to the heart and draining vein and its avoidance. Between February 2007 and August 2008, Onyx migration was encountered in five patients with dural AVFs treated endovascularly at our institute. Procedures performed under general anesthesia consisted of two arterial approaches and three venous approaches. Two patients with dural AVFs involving the transverse-sigmoid sinus were treated by tran- sarterial embolization using Onyx-18 via the occipital artery and the posterior branch of the middle meningeal artery, respectively. A piece of Onyx was found in the right ventricle on post- embolization chest X-ray film in both patients, one developed tricuspid valve dysfunction requiring thoracic surgery and one was asymptomatic. The other three patients were treated with a combination of Onyx (34 or 18) and coils transvenously with venous Onyx migration leading to draining vein occlusion, one with dur- al AVF involving the tentorium died from venous rupture, two patients with bilateral dural AVFs of the cavernous sinus (one with deterioration of ocular symptoms and one without symptoms). Postoperative digital subtraction an- giography confirmed the elimination of dural AVF in one patient, and residual fistulae in three patients. The follow-up study ranging from two to nine months (average, 4.5 months). Three patients recovered to their full activities, while one had visual disturbance. Although Onyx has been considered a controllable embolic agent, its migration to other locations causing clinical deterioration can occur. This problem should be noted and prevented. PMID:20465913

Enlarged Dural Sac in Idiopathic Bronchiectasis Implicates Heritable Connective Tissue Gene Variants

Birchard, Katherine R.; Lowe, Jared R.; Patrone, Michael V.

Rationale: Patients with idiopathic bronchiectasis are predominantly female and have an asthenic body morphotype and frequent nontuberculous mycobacterial respiratory infections. They also demonstrate phenotypic features (scoliosis, pectus deformity, mitral valve prolapse) that are commonly seen in individuals with heritable connective tissue disorders. Objectives: To determine whether lumbar dural sac size is increased in patients with idiopathic bronchiectasis as compared with control subjects, and to assess whether dural sac size is correlated with phenotypic characteristics seen in individuals with heritable connective tissue disorders. Methods: Two readers blinded to diagnosis measured anterior–posterior and transverse dural sac diameter using L1–L5 magnetic resonance images of 71 patients with idiopathic bronchiectasis, 72 control subjects without lung disease, 29 patients with cystic fibrosis, and 24 patients with Marfan syndrome. We compared groups by pairwise analysis of means, using Tukey’s method to adjust for multiple comparisons. Dural sac diameter association with phenotypic and clinical features was also tested. Measurements and Main Results: The L1–L5 (average) anterior–posterior dural sac diameter of the idiopathic bronchiectasis group was larger than those of the control group (P < 0.001) and the cystic fibrosis group (P = 0.002). There was a strong correlation between increased dural sac size and the presence of pulmonary nontuberculous mycobacterial infection (P = 0.007) and long fingers (P = 0.003). A trend toward larger dural sac diameter was seen in those with scoliosis (P = 0.130) and those with a family history of idiopathic bronchiectasis (P = 0.149). Conclusions: Individuals with idiopathic bronchiectasis have an enlarged dural sac diameter, which is associated with pulmonary nontuberculous mycobacterial infection, long fingers, and family history of idiopathic bronchiectasis. These findings support our

Although epidural anesthesia is considered safe, several complications may occur during puncture and insertion of a catheter. Incidences of paresthesia vary between 0.2 and 56%. A prospective, open, cohort-controlled pilot study was conducted in 188 patients, ASA I-III, age 19-87 years, scheduled for elective surgery and epidural anesthesia. We evaluated a 20 G polyamide (standard) catheter and a 20 G combined polyurethane-polyamide (new) catheter. Spontaneous reactions upon catheter-insertion, paresthesia on questioning, inadvertent dural or intravascular puncture, and reasons for early catheter removal were recorded. The incidence of paresthesia reported spontaneously was 21.3% with the standard catheter and 16.7% with the new catheter. Systematically asking for paresthesia almost doubled the paraesthesia rate. Intravascular cannulation occurred in 5%. No accidental dural punctures occurred. An overall incidence of 13.3% of technical problems led to early catheter removal. The new catheter was at least equivalent to the standard regarding epidural success rate and safety : rate of paresthesia, intravascular and dural cannulation.

A high incidence of postdural puncture headache (PDPH) occurs after spinal anesthesia for cesarean section. To examine this problem, a study was conducted with the recently developed 24-gauge Sprotte and 27-gauge Quincke needles in patients undergoing elective and emergency cesarean section (n = 298). The needle to be used was assigned in a random manner: group I, 27-gauge Quincke (n = 147); group II, 24-gauge Sprotte (n = 151). During the postoperative period, patients were visited daily and asked specifically about the presence and severity of headache. The overall incidence of PDPH was 2% (n = 6), five in the Quincke group (3.5%) and one in the Sprotte group (0.7%). There was no significant difference in the incidence of PDPH between the two groups. Five headaches were classified as mild, and only one was moderate to severe. All headaches resolved quickly with conservative management and without blood patch. The authors conclude that the choice between a 27-gauge Quincke and a 24-gauge Sprotte needle does not influence the incidence of PDPH after spinal anesthesia for cesarean section.

Sorenson, Thomas J; La Pira, Biagia; Hughes, Joshua; Lanzino, Giuseppe

2017-08-01

Dural arteriovenous fistulas (DAVFs) of the craniocervical junction are uncommon vascular lesions, which often require surgical treatment even in the endovascular era. Most commonly, the fistula is placed laterally, and surgical ligation is performed through a lateral suboccipital craniotomy. After dural opening, the area is inspected, and the arterialized vein is identified emerging from the dura, often adjacent to the entry point of the vertebral artery, and ligated. A far lateral craniotomy is the authors' preferred surgical approach for accessing and treating dural arteriovenous fistulas of the craniocervical junction that cannot be reached endovascularly.

Watertight dural closure is imperative after neurosurgical procedures because inadequately treated leakage of cerebrospinal fluid (CSF) can have serious consequences. In this study, the authors test the use of a new gelatin glue as a dural sealant in in vitro and in vivo canine models of transdural CSF leakage. The in vitro model was sutured semicircles of canine dura mater and artificial dural substitute. The sutures were sealed with gelatin glue (n  =  20), fibrin glue (n  =  20), or a polyethylene glycol (PEG)-based hydrogel sealant (n  =  20). Each sample was set in a device to measure water pressure, and pressure was increased until leakage occurred. Bonding strength was subjectively evaluated. The in vivo model was dogs who underwent dural excision and received either no sealant (control group; n  =  5) or gelatin glue sealant (n  =  5) before dural closure. Twenty-eight days post-surgery, the maximum intracranial pressure was measured at the cisterna magna using Valsalva maneuver and tissue adhesion was evaluated. The water pressure at which leakage occurred in the in vitro model was higher with gelatin glue (76·5 ± 39·8 mmHg) than with fibrin glue (38·3 ± 27·4 mmHg, P < 0·001) or the PEG-based hydrogel sealant (46·3 ± 20·9 mmHg, P  =  0·007). Bonding strength was higher for the gelatin glue than fibrin glue (P < 0·001) or PEG-based hydrogel sealant (P  =  0·001). The maximum intracranial pressure in the in vivo model was higher for the gelatin glue group (59·0 ± 2·2 mmHg) than the control group (13·8 ± 4·0 mmHg, P < 0·001). Tissue adhesion was lower for the gelatin glue group than the control group (P  =  0·005). The new gelatin glue provides an effective watertight closure when used as an adjunct to sutured dural repair.

Dural sinuses vary in size and shape in many pathological conditions with abnormal intracranial pressure. Size and shape normograms of dural brain sinuses are not available. The creation of such normograms may enable computer-assisted comparison to pathologic exams and facilitate diagnoses. The purpose of this study was to quantitatively evaluate normal magnetic resonance venography (MRV) studies in order to create normograms of dural sinuses using a computerized algorithm for vessel cross-sectional analysis. This was a retrospective analysis of MRV studies of 30 healthy persons. Data were analyzed using a specially developed Matlab algorithm for vessel cross-sectional analysis. The cross-sectional area and shape measurements were evaluated to create normograms. Mean cross-sectional size was 53.27±13.31 for the right transverse sinus (TS), 46.87+12.57 for the left TS (p=0.089) and 36.65+12.38 for the superior sagittal sinus. Normograms were created. The distribution of cross-sectional areas along the vessels showed distinct patterns and a parallel course for the median, 25th, 50th and 75th percentiles. In conclusion, using a novel computerized method for vessel cross-sectional analysis we were able to quantitatively characterize dural sinuses of healthy persons and create normograms.

To improve the efficacy and safety of dural repair in neurosurgical procedures, a new dural material derived from bacterial cellulose (BC) was evaluated in a rabbit model with dural defects. We prepared artificial dura mater using bacterial cellulose which was incubated and fermented from Acetobacter xylinum. The dural defects of the rabbit model were repaired with BC membranes. All surgeries were performed under sodium pentobarbital anesthesia, and all efforts were made to minimize suffering. All animals were humanely euthanized by intravenous injection of phenobarbitone, at each time point, after the operation. Then, the histocompatibility and inflammatory effects of BC were examined by histological examination, real-time fluorescent quantitative polymerase chain reaction (PCR) and Western Blot. BC membranes evenly covered the surface of brain without adhesion. There were seldom inflammatory cells surrounding the membrane during the early postoperative period. The expression of inflammatory cytokines IL-1β, IL-6 and TNF-α as well as iNOS and COX-2 were lower in the BC group compared to the control group at 7, 14 and 21 days after implantation. BC can repair dural defects in rabbit and has a decreased inflammatory response compared to traditional materials. However, the long-term effects need to be validated in larger animals.

To evaluate the efficacy of dural tenting suture and epidural drainage in craniotomy. In 145 cases of intracranial lesions, dural tenting suture and epidural drainage were performed to prevent epidural hematoma. Postoperative computed tomography (CT) showed no epidural hematoma required surgery in both groups. Both dural tenting suture and epidural drainage are effective in preventing epidural hematoma. Hemostasis is the key step. Dural tenting suture without epidural drainage relieves psychological stress. It decreases the risk of intracranial infection and avoids some unusual complications.

Transseptal punctures (TSP) are routinely performed in cardiac interventions requiring access to the left heart. While pericardial effusion/tamponade are well-recognized complications, few data exist on accidental puncture of the aorta and its management and outcome. We therefore analysed our single centre database for this complication. We assessed frequency and outcome of inadvertent aortic puncture during TSP in consecutive patients undergoing ablation procedures between January 2005 and December 2014. During the 10-year period, two inadvertent aortic punctures occurred among 2936 consecutive patients undergoing 4305 TSP (0.07% of patients, 0.05% of TSP) and in one Mustard patient during attempted baffle puncture. The first two patients required left ventricular access for catheter ablation of ventricular tachycardia. In both cases, an 11.5F steerable sheath (inner diameter 8.5F) was accidentally placed in the ascending aorta just above the aortic valve. In the presence of surgical standby, the sheaths were pulled back with a wire left in the aorta. Under careful haemodynamic and echocardiographic observation, this wire was also pulled back 30 min later. None of the patients required a closing device or open heart surgery. None of the patients suffered complications from the accidental aortic puncture and sheath placement. Inadvertent aortic puncture and sheath placement are rare complications in patients undergoing TSP for interventional procedures. Leaving a guidewire in place during the observation period may allow introduction of sheaths or other tools in order to control haemodynamic deterioration.

Primary Headache Disorders- Part 2: Tension-type headache and medication overuse headache.

PubMed

Jay, Gary W; Barkin, Robert L

2017-12-01

In Part 2 of Primary Headache disorders, we discuss the fourth Primary Headache Disorder, Tension-Type Headache (TTHA). We are again using the ICHD-III (Beta) definitions of such headaches, taking into consideration episodic and chronic TTHA, as well as the presence or absence of pericranial muscle tenderness. We discuss the pathophysiology and pharmacotherapeutic treatment of TTHA, and the aspects of the Myofascial Pain Syndrome that enhance and help the development of TTHA. We then discuss Medication Overuse Headache (MOH), itself a Secondary headache disorder, but one that is extremely important as it assists with the chronification of both migraine and TTHA. Finally we discuss how to manage and treat those patients with MOH. Chronic migraine, which is TTHA, Migraine as well as, in many patients, MOH, is discussed along with the treatment of this multifaceted disorder. Copyright © 2017 Elsevier Inc. All rights reserved.

Cranial dural arteriovenous shunts. Part 1. Anatomy and embryology of the bridging and emissary veins.

PubMed

Baltsavias, Gerasimos; Parthasarathi, Venkatraman; Aydin, Emre; Al Schameri, Rahman A; Roth, Peter; Valavanis, Anton

2015-04-01

We reviewed the anatomy and embryology of the bridging and emissary veins aiming to elucidate aspects related to the cranial dural arteriovenous fistulae. Data from relevant articles on the anatomy and embryology of the bridging and emissary veins were identified using one electronic database, supplemented by data from selected reference texts. Persisting fetal pial-arachnoidal veins correspond to the adult bridging veins. Relevant embryologic descriptions are based on the classic scheme of five divisions of the brain (telencephalon, diencephalon, mesencephalon, metencephalon, myelencephalon). Variation in their exact position and the number of bridging veins is the rule and certain locations, particularly that of the anterior cranial fossa and lower posterior cranial fossa are often neglected in prior descriptions. The distal segment of a bridging vein is part of the dural system and can be primarily involved in cranial dural arteriovenous lesions by constituting the actual site of the shunt. The veins in the lamina cribriformis exhibit a bridging-emissary vein pattern similar to the spinal configuration. The emissary veins connect the dural venous system with the extracranial venous system and are often involved in dural arteriovenous lesions. Cranial dural shunts may develop in three distinct areas of the cranial venous system: the dural sinuses and their interfaces with bridging veins and emissary veins. The exact site of the lesion may dictate the arterial feeders and original venous drainage pattern.

New daily-persistent headache versus tension-type headache.

PubMed

Robbins, Matthew S; Crystal, Sara C

2010-12-01

New daily-persistent headache (NDPH) and chronic tension-type headache (CTTH) are two forms of primary chronic daily headache of long duration that often are similar in their headache manifestations. NDPH distinguishes itself from CTTH and the other forms of chronic daily headache by its continuous head pain from onset. However, despite formalized criteria that specify NDPH must resemble the acute onset of a headache identical to that of CTTH, NDPH commonly has migraine features. Here, we review the available literature on NDPH and compare its clinical features, epidemiology, prognosis, inciting factors, and treatment to CTTH.

Cerebrospinal fluid collection by lumbar puncture (LP) is performed in the diagnostic workup of several neurological brain diseases. Reluctance to perform the procedure is among others due to a lack of standards and guidelines to minimize the risk of complications, such as post-LP headache or back pain. We provide consensus guidelines for the LP procedure to minimize the risk of complications. The recommendations are based on (1) data from a large multicenter LP feasibility study (evidence level II-2), (2) systematic literature review on LP needle characteristics and post-LP complications (evidence level II-2), (3) discussion of best practice within the Joint Programme Neurodegenerative Disease Research Biomarkers for Alzheimer's disease and Parkinson's Disease and Biomarkers for Multiple Sclerosis consortia (evidence level III). Our consensus guidelines address contraindications, as well as patient-related and procedure-related risk factors that can influence the development of post-LP complications. When an LP is performed correctly, the procedure is well tolerated and accepted with a low complication rate.

A 40-year-old man presented with a severe headache, lower back pain, and lower abdominal pain 1 month after a head injury caused by falling. Computed tomography (CT) of the head demonstrated bilateral chronic subdural hematoma (CSDH) with a significant amount in the left frontoparietal region. At the same time, magnetic resonance imaging (MRI) of the lumbar spine also revealed CSDH from L2 to S1 level. A simple drainage for the intracranial CSDH on the left side was performed. Postoperatively, the headache was improved; however, the lower back and abdominal pain persisted. Aspiration of the liquefied spinal subdural hematoma was performed by a lumbar puncture under fluoroscopic guidance. The clinical symptoms were dramatically improved postoperatively. Concomitant intracranial and spinal CSDH is considerably rare so only 23 cases including the present case have been reported in the literature so far. The etiology and therapeutic strategy were discussed with a review of the literature. Therapeutic strategy is not established for these two concomitant lesions. Conservative follow-up was chosen for 14 cases, resulting in a favorable clinical outcome. Although surgical evacuation of lumbosacral CSDH was performed in seven cases, an alteration of cerebrospinal fluid (CSF) pressure following spinal surgery should be reminded because of the intracranial lesion. Since CSDH is well liquefied in both intracranial and spinal lesion, a less invasive approach is recommended not only for an intracranial lesion but also for spinal lesion. Fluoroscopic-guided lumbar puncture for lumbosacral CSDH following burr hole surgery for intracranial CSDH could be a recommended strategy. PMID:29479039

A dural metastasis is one of the essential differential diagnoses of meningioma. In general, carcinomas of the breast and lung in females and prostate in males have been the most commonly reported primary lesions of dural metastases. However, dural metastasis of gallbladder carcinoma is extremely rare. Here, we report a unique case of a dural matter metastasis of gallbladder carcinoma as the first manifestation, which was autopsy-defined as small cell carcinoma. A 78-year-old man came to our hospital complaining of left hemianopia. Brain computed tomography (CT) revealed a sizeable parasagittal dural-based extra-axial tumor. However, the findings for meningioma were atypical by magnetic resonance imaging, suggesting a meningioma mimic. A contrast-enhanced CT scan of the abdomen revealed a large gallbladder carcinoma. The patient opted for the best supportive care and died 2 months later. The post-mortem examination revealed small cell carcinoma in gallbladder carcinoma. Moreover, an immunologically similar carcinoma was detected in the dural metastasis. To the best of our knowledge, this is the first case of a dural metastasis of gallbladder small cell carcinoma. A systemic examination is essential for clinicians when atypical findings of meningioma are observed, suggesting a meningioma mimic. We present this rare case with a review of the literature.

Surgical management of dural arteriovenous fistulas with transosseous arterial feeders involving the jugular bulb.

PubMed

2007-01-01

Dural arteriovenous fistulas located in the vicinity of the jugular foramen are complex vascular malformations and belong to the most challenging skull base lesions to treat. The authors comprehensively analyze multiple features in a series of dural arteriovenous fistulas with transosseous arterial feeders involving the jugular bulb. Four patients who underwent surgery via the transcondylar approach to treat dural arteriovenous fistulas around the jugular foramen were retrospectively reviewed. Previously, endovascular treatment was attempted in all patients. The success of the surgical treatment was examined with postoperative angiography. Complete obliteration of the dural arteriovenous fistulas (DAVFs) was achieved in three patients, and significant flow reduction in one individual. All patients had a good postoperative outcome, and only one experienced mild hypoglossal nerve palsy. Despite extensive bone drilling, an occipitocervical fusion was necessary in only one patient with bilateral lesions. The use of an individually tailored transcondylar approach to treat dural arteriovenous fistulas at the region of the jugular foramen is most effective. This approach allows for complete obliteration of the connecting arterial feeders, and removal of bony structures containing pathological vessels.

Detector location selection based on VIP analysis in near-infrared detection of dural hematoma.

Detection of dural hematoma based on multi-channel near-infrared differential absorbance has the advantages of rapid and non-invasive detection. The location and number of detectors around the light source are critical for reducing the pathological characteristics of the prediction model on dural hematoma degree. Therefore, rational selection of detector numbers and their distances from the light source is very important. In this paper, a detector position screening method based on Variable Importance in the Projection (VIP) analysis is proposed. A preliminary modeling based on Partial Least Squares method (PLS) for the prediction of dural position μ a was established using light absorbance information from 30 detectors located 2.0-5.0 cm from the light source with a 0.1 cm interval. The mean relative error (MRE) of the dural position μ a prediction model was 4.08%. After VIP analysis, the number of detectors was reduced from 30 to 4 and the MRE of the dural position μ a prediction was reduced from 4.08% to 2.06% after the reduction in detector numbers. The prediction model after VIP detector screening still showed good prediction of the epidural position μ a . This study provided a new approach and important reference on the selection of detector location in near-infrared dural hematoma detection.

Objective Treatment of intracranial dural arteriovenous fistulas (dAVFs) remains a challenge. However, after introduction of Onyx, transarterial approach is the preferred treatment option in many centers. We report our experience of dAVFs embolization with special emphasis on transarterial approach. Methods Seventeen embolization procedures were performed in 13 patients with dAVFs between Jan 2009 and Oct 2014. Clinical symptoms, location and type of fistulas, embolization methods, complications, radiological and clinical outcomes were evaluated using charts and PACS images. Results All 13 patients had symptomatic lesions. The locations of fistulas were transverse-sigmoid sinus in 6, middle fossa dura in 4, cavernous sinus in 2, and superior sagittal sinus in 1 patient. Cognard types were as follows : I in 4, IIa in 2, IIa+IIb in 5, and IV in 2. Embolization procedures were performed ≥2 times in 3 patients. Nine patients were treated with transarterial Onyx embolization alone. One of these required direct surgical puncture of middle meningeal artery. Complete obliteration of fistulas was achieved in 11/13 (85%) patients. There were no complications except for 1 case of Onyx migration in cavernous dAVF. Modified Rankin scale score at post-operative 3 months were 0 in 11, and 3 in 2 patients. Conclusion Transarterial Onyx embolization can be a first line therapeutic option in patients with dAVFs. However, transvenous approach should be tried first in cavernous sinus dAVF because of the risk of intracranial migration of liquid embolic materials. Furthermore, combined surgical endovascular approach can be considered as a useful option in inaccessible route. PMID:26885282

A precondition for the successful treatment of headaches is the correct headache diagnosis. Triptans are effective for attack treatment of migraine and cluster headache. However, there are not effective for the treatment of tension-type headache. For the prevention of frequent episodic migraine betablockers, flunarizine, topiramate and amitriptyline are recommended. For the prevention of chronic migraine evidence is only available for onabotulinumtoxinA and topiramate. For prophylactic treatment of tension-type headaches tricyclic antidepressants are used. In cluster headache verapamil (in combination with steroids) is the most frequently used prophylactic agent. This article focusses on the current acute and prophylactic treatment of common headache syndromes. © Georg Thieme Verlag KG Stuttgart · New York.

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

The purposes of this study were to demonstrate that laser soldering is safe and effective for tissue bonding in dural reconstruction and to compare this new reconstruction technique to an established one. A temperature-controlled fiberoptic CO(2) laser system or fibrin glue were used for in vitro dural defect reconstruction in two groups of pigs. The CO(2) laser technique was also used for dural reconstruction in live pigs. The burst pressure of the reconstructed dura by the laser system was significantly higher than that of fibrin glue (mean pressure 258.5 +/- 117.3 cm H(2)O and 76.8 +/- 47.2 cm H(2)O, respectively). There were no postoperative complications and no signs of thermal damage to the dura, fascia, or underlying tissue on histological analysis following the in vivo CO(2) laser experiments. Temperature-controlled laser soldering is an effective technique for dural repair. It creates a strong tissue bonding with no thermal damage to the tissue. The burst pressure of the reconstructed dura done with laser soldering is significantly higher than that of fibrin glue.

International Headache Society classification: new proposals about chronic headache.

Manzoni, G C; Torelli, P

2003-05-01

In the International Headache Society (IHS) classification of 1988, chronic daily headache (CDH) forms are not exhaustively categorized. The forthcoming revision of the classification will include a number of CDH forms that had been reported prior to 1988 or have been identified after that date. In particular, chronic migraine will be added to the classification as a complication of migraine, provided that use of symptomatic drugs does not exceed 10 days per month. In addition to chronic cluster headache and chronic paroxysmal hemicrania, short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) and hemicrania continua will be comprised among CDH forms with short-lived attacks. Hypnic headache will be included in Group 4 ("Other primary headaches"). No additions will be made to the new IHS classification for forms such as new daily persistent headache (NDPH) and cervicogenic headache as proposed by Sjaastad.

[Investigation of fat in the dural sinus].

PubMed

Tokiguchi, S

1991-08-25

Detection of fat in the cranium usually indicates the presence of a fat-containing tumor such as lipoma, dermoid cyst or teratoma. However, since 1982, Hasso et al demonstrated with CT the presence of normal adipose tissue in the cavernous sinus, the mere existence of fat in the cranium does not necessarily mean the presence of a fatty tumor. The author first described fat deposition in the superior sagittal sinus and torcular Herophili following a CT study performed in 1986. The purpose of this study was to investigate the distribution, frequency, and anatomical correlations of fat in the dural sinus as demonstrated on CT. Fat was detected in the cavernous sinus in 20% of all cases (492/2408), and occurred more frequently (25%) in those older than 50 years. Fat was less frequent in the other dural sinuses (3%; 75/2296). The most common location was the torcular Herophili, followed in decreasing order of frequency by the straight sinus, inferior sagittal sinus, superior sagittal sinus and transverse sinus. Pathological examination was performed in three cases. Fat deposition was composed of normal adipose tissue and was devoid of fibrous encapsulation or infiltration. In one case, the fat seemed to be partly exposed to the subarachnoid space on CT, whereas on autopsy, thin dura mater covering the fat nodule was confirmed. Fat in the dural sinus must be differentiated from cavernous nodule or sinus thrombosis. The Hounsfield unit may be helpful in making a definitive diagnosis.

Dural ectasia associated with Mounier-Kuhn syndrome: a novel association in the context of spinal stenosis.

PubMed

Sheridan, Gerard Anthony; Godkin, Owen; Devitt, Aiden

2017-08-30

We present the case of a patient undergoing lumbar spine decompression for stenosis with a history of Mounier-Kuhn syndrome. The patient presented with axial lumbar spine pain over 6 months with progressive radicular pain to the left L3 dermatome. MRI confirmed spinal stenosis at L3/4 level with associated dural ectasia. The patient had an uneventful spinal decompression with resolution of radicular symptoms and axial spine pain. Dural ectasia poses a significant risk when operating on the lumbosacral spine. Larger cerebrospinal fluid volumes and a capacious dural canal can result in anaesthetic and orthopaedic complications such as inadequate spinal anaesthesia, complicated epidural analgesia, intraoperative dural tears and difficult pedicle screw insertion due to narrow pedicles. This is the first case in the literature detailing the association between dural ectasia and Mounier-Kuhn syndrome. We recommend adequate spinal imaging in patients with Mounier-Kuhn syndrome to exclude dural ectasia prior to undergoing lumbosacral spinal procedures. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Rare nocturnal headaches.

PubMed

Cohen, Anna S; Kaube, Holger

2004-06-01

This review describes rare headaches that can occur at night or during sleep, with a focus on cluster headaches, paroxysmal hemicrania, short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing, hypnic headache and exploding head syndrome. It is known that cluster headaches and hypnic headache are associated with rapid eye movement sleep, as illustrated by recent polysomnographic studies. Functional imaging studies have documented hypothalamic activation that is likely to be of relevance to circadian rhythms. These headache syndromes have been shown to respond to melatonin and lithium therapy, both of which have an indirect impact on the sleep-wake cycle. There is growing evidence that cluster headache and hypnic headache are chronobiological disorders.

A thrombophilic patient with a dural arteriovenous fistula presenting sensory aphasia and complicated with an acute pulmonary embolism.

2008-09-01

Neuropsychiatric symptoms as the initial presentation of dural arteriovenous fistula (DAVF) are unusual. Anticoagulation therapy may be warranted for prevention of further thromboembolism if an underlying thrombophilia condition is diagnosed. We present a 70-year-old woman with sensory aphasia, who was diagnosed with a DAVF, Cognard type II a + b, by cerebral angiography. Her stroke-like syndrome resolved after transarterial embolization of the left occipital and middle meningeal arteries. Meanwhile, hypercoagulability was found because of hyperhomocysteinemia and the presence of a lupus anticoagulant. One month later, she suffered an acute pulmonary embolism and was started on anticoagulation therapy before stereotactic radiosurgery. Sensory aphasia may be the initial manifestation of a transverse-sigmoid sinus DAVF even if there are no symptoms such as headache or tinnitus. We postulate that early anticoagulation therapy is indicated for preventing thromboembolism in DAVF patients with thrombophilia because the possibility of intracranial bleeding has been reduced by embolization.

Whiplash headache is transitory worsening of a pre-existing primary headache.

2008-07-01

Acute and chronic whiplash headache are new diagnostic entities in the ICHD-2 (5.3, 5.4). In a prospective cohort study, 210 rear-end collision victims were identified consecutively from police records and asked about head and neck pain in questionnaires after 2 weeks, 3 months and 1 year. The results were compared with those of matched controls who were also followed for 1 year. Of 210 accident victims, 75 developed headache within 7 days. Of these, 37 had also neck pain and complied with the criteria for acute whiplash headache. These 37 had the same headache diagnoses, headache features, accompanying symptoms and long-term prognosis as the 38 without initial neck pain who therefore did not comply with the acute whiplash headache diagnosis. Previous headache was a major risk factor for headache both in the acute and chronic stage. Compared with the non-traumatized controls, headache in the whiplash group had the same prevalence, the same diagnoses and characteristic features, and the same prognosis. Both acute and chronic whiplash headache lack specificity compared with the headache in a control group, and have the same long-term prognosis, indicating that such headaches are primary headaches, probably elicited by the stress of the situation.

Self-reported headache in schoolchildren: parents underestimate their children's headaches.

Most previous studies of childhood headache have used indirect parental/physician reports to estimate the prevalence of headache in children. To use direct information from children and to compare the results with data collected from parents. A cross-sectional questionnaire was sent to parents of 7-12-y-olds in Oslo, Norway. The questionnaire included retrospective reports by the parents of the presence of headache among their children during the past 6 mo. A panel study was subsequently done with daily diaries completed by the children over 6 wk. This was done at school. For 2126 children, both diary reports and parental reports were available. We found a 1-mo prevalence of self-reported headache of 57.6%. Parents, particularly fathers, reported lower headache prevalence than the children. The difference between parental reports and those of the children was larger when the child was a girl. There was a clear difference for the youngest children and parental underreporting for children with the most frequent headaches. Since indirect parental reports of child headache underestimated headache frequency compared to direct diary-based self-reports, we suggest more widespread use of diary registration of headaches in studies of child headache.

Novel laser tissue-soldering technique for dural reconstruction.

2005-07-01

The goal of this study was to use a modified version of the CO2 laser-soldering system to develop a simple and reliable technique for the repair of dural defects after excision of brain tumors. The authors used a CO2 fiber optic laser system that they had developed for heating, monitoring, and controlling tissue temperature in situ and in real time, thereby reducing damage to the brain parenchyma. They adapted the system for dural closure by using free fascial grafts in a porcine model. Measures for estimation of reconstruction quality included visual assessment under magnification and direct measurements of adhesive strength and cerebrospinal fluid leak (CSF) pressure. Reliable soldering was achieved in 54 of 57 experiments, providing a 95% success rate. The average peak adhesive strength was 82 +/- 3 mN/cm2. The measured leak pressure of the fascia-dura mater bond was 66 +/- 5 mm Hg. Conventional suturing performed using Prolene stitches resulted in immediate CSF leakage from areas between the stitches and from the area of the needle hole itself. Fascia-dura mater soldering using the CO2 laser is feasible and may support CSF pressure up to six times higher than normal intracranial pressure. Findings of this study may provide a basis for the development of new tools for dural reconstruction.

Dural arteriovenous fistulas are acquired lesions between the meningeal arteries and their associated draining veins. They may have highly variable clinical presentations and evolution, from severe neurological deficit to no or trivial symptoms. Intracranial hemorrhage occurs in less than 24% of all dural fistulas, and the bleeding is usually subarachnoid, more infrequently intracerebral, and rarely in the subdural space. Here, we present a rare case of a patient who presented with a subdural spontaneous hemorrhage. After investigation by cerebral angiography, the diagnosis of a dural arteriovenous fistula was made. The patient underwent uneventful endovascular treatment. As there are with only a few reports in the literature of such a presentation, we present this patient and perform a brief review of the literature. Copyright © 2015 Elsevier Ltd.

Stress and Sleep Duration Predict Headache Severity in Chronic Headache Sufferers

2013-01-01

The objective of this study was to evaluate the time-series relationships between stress, sleep duration, and headache pain among patients with chronic headaches. Sleep and stress have long been recognized as potential triggers of episodic headache (< 15 headache days/month), though prospective evidence is inconsistent and absent in patients diagnosed with chronic headaches (≥ 15 days/month). We reanalyzed data from a 28-day observational study of chronic migraine (n = 33) and chronic tension-type headache (n = 22) sufferers. Patients completed the Daily Stress Inventory and recorded headache and sleep variables using a daily sleep/headache diary. Stress ratings, duration of previous nights' sleep, and headache severity were modeled using a series of linear mixed models with random effects to account for individual differences in observed associations. Models were displayed using contour plots. Two consecutive days of either high stress or low sleep were strongly predictive of headache, whereas two days of low stress or adequate sleep were protective. When patterns of stress or sleep were divergent across days, headache risk was increased only when the earlier day was characterized by high stress or poor sleep. As predicted, headache activity in the combined model was highest when high stress and low sleep occurred concurrently during the prior 2 days denoting an additive effect. Future research is needed to expand on current findings among chronic headache patients and to develop individualized models that account for multiple simultaneous influences of headache trigger factors.

Anterior dural ectasia is an extremely rare finding in ankylosing spondylitis (AS). The authors describe a unique case of AS in which the patient presented with cauda equina syndrome as well as an unusual imaging finding of erosion of the posterior aspect of the L-1 (predominantly) and L-2 vertebral bodies due to anterior dural ectasia. Symptomatic patients with long-standing AS should be monitored for the presence of dural ectasia, which can be anterior in location, as is demonstrated in the present case.

Headache in sports.

PubMed

Seifert, Tad

2014-09-01

Sports- and exercise-related headaches are not unusual. Despite their frequent occurrence in this context, there are little epidemiologic data concerning sports-related headache. The recent attention of concussive injuries and associated post-traumatic headache has renewed interest in the study of those headaches occurring after head trauma; however, any primary headache type can also occur in the setting of contact and/or collision sports. The nonspecific nature of headaches provides unique challenges to clinicians encountering this complaint. It is, therefore, imperative that physicians treating athletes are able to distinguish the various headache types and presentations often seen in this population.

A 37-year-old female presented with medically intractable complex partial seizures with secondary generalization. She was found to have a dural-based lesion with radiologic features of meningioma. A gross total resection was performed and pathology confirmed a diagnosis of cavernous angioma and she became seizure free after the surgical resection. Cavernous angioma should be considered in differential diagnosis of a dural-based lesion manifesting with refractory seizures.

The objective of this study was to evaluate the time-series relationships between stress, sleep duration, and headache pain among patients with chronic headaches. Sleep and stress have long been recognized as potential triggers of episodic headache (<15 headache days/month), though prospective evidence is inconsistent and absent in patients diagnosed with chronic headaches (≥15 days/month). We reanalyzed data from a 28-day observational study of chronic migraine (n=33) and chronic tension-type headache (n=22) sufferers. Patients completed the Daily Stress Inventory and recorded headache and sleep variables using a daily sleep/headache diary. Stress ratings, duration of previous nights' sleep, and headache severity were modeled using a series of linear mixed models with random effects to account for individual differences in observed associations. Models were displayed using contour plots. Two consecutive days of either high stress or low sleep were strongly predictive of headache, whereas 2 days of low stress or adequate sleep were protective. When patterns of stress or sleep were divergent across days, headache risk was increased only when the earlier day was characterized by high stress or poor sleep. As predicted, headache activity in the combined model was highest when high stress and low sleep occurred concurrently during the prior 2 days, denoting an additive effect. Future research is needed to expand on current findings among chronic headache patients and to develop individualized models that account for multiple simultaneous influences of headache trigger factors.

Using magnetic resonance (MR) imaging, we studied brain injury from ventricular puncture performed during craniotomy in the acute stage of subarachnoid hemorrhage (SAH). 80 patients underwent craniotomy for aneurysm obliteration within 48 hr after SAH, ventricular puncture for drainage of cerebrospinal fluid (CSF) was performed to reduce intracranial pressure. MR imaging was performed within 3 days following surgery to measure the size of the lesion, and was repeated on postoperative days 14 and 30. Of the 80 patients with ventricular puncture preceding craniotomy, 65 (81%) showed MR evidence of brain injury from the puncture. Overall, 149 lesions were detected. According to coronal images, cortical injuries (54 cases), penetrating injury to tracts along the ventricular tube (55 cases), caudate injury (25 cases), and corpus callosum injury (15 cases). Brain injuries from ventricular puncture did not correlate significantly to patient outcome. While ventricular puncture and drainage of CSF can readily be performed to decrease brain volume at the time of craniotomy in acute-stage SAH, neurosurgeons should be aware of a surprisingly high incidence of brain injury complicating puncture.

The central nervous system (CNS) is considered an organ devoid of lymphatic vasculature. Yet, part of the cerebrospinal fluid (CSF) drains into the cervical lymph nodes (LNs). The mechanism of CSF entry into the LNs has been unclear. Here we report the surprising finding of a lymphatic vessel network in the dura mater of the mouse brain. We show that dural lymphatic vessels absorb CSF from the adjacent subarachnoid space and brain interstitial fluid (ISF) via the glymphatic system. Dural lymphatic vessels transport fluid into deep cervical LNs (dcLNs) via foramina at the base of the skull. In a transgenic mouse model expressing a VEGF-C/D trap and displaying complete aplasia of the dural lymphatic vessels, macromolecule clearance from the brain was attenuated and transport from the subarachnoid space into dcLNs was abrogated. Surprisingly, brain ISF pressure and water content were unaffected. Overall, these findings indicate that the mechanism of CSF flow into the dcLNs is directly via an adjacent dural lymphatic network, which may be important for the clearance of macromolecules from the brain. Importantly, these results call for a reexamination of the role of the lymphatic system in CNS physiology and disease. PMID:26077718

Background and Purpose Chronic daily headache (CDH) is defined as a headache disorder in which headaches occur on a daily or near-daily basis (at least 15 days/month) for more than 3 months. Chronic migraine (CM) and medication overuse headache (MOH) are very disabling headaches that remain underdiagnosed. The aim of this study was to establish the frequency of CDH and its various subtypes, and examine the associations with MOH among first-visit headache patients presenting at neurology outpatient clinics in Korea. Methods Eleven neurologists enrolled first-visit patients with complaints of headaches into outpatient clinics for further assessment. Headache disorders were classified according to the International Classification of Headache Disorder (third edition beta version) by each investigator. Results Primary CDH was present in 248 (15.2%) of the 1,627 included patients, comprising CM (143, 8.8%), chronic tension-type headache (CTTH) (98, 6%), and definite new daily persistent headache (NDPH) (7, 0.4%). MOH was associated with headache in 81 patients (5%). The association with MOH was stronger among CM patients (34.5%) than patients with CTTH (13.3%) or NDPH (14.3%) (p=0.001). The frequency of CDH did not differ between secondary and tertiary referral hospitals. Conclusions The frequencies of CDH and MOH diagnoses were 15.2% and 5%, respectively in first-visit headache patients presented at secondary or tertiary referral hospitals in Korea. CM was the most common subtype of CDH and was most frequently associated with MOH. PMID:27449912

Headache is one of the most frequently encountered neurological symptoms during hemodialysis. According to International Classification of Headache criteria dialysis-related headache was defined as the headache occurring during hemodialysis with no specific characteristic. It resolves spontaneously within 72 hours after the hemodialysis session ends. There are few studies in the literature investigating the clinical features of dialysis headache. The pathophysiology of hemodialysis-related headache is not known, but various triggering factors have been identified, including changes in blood pressure, serum sodium and magnesium levels during hemodialysis sessions, caffeine deprivation and stress. The aim of this article is to evaluate and analyze features of headache in patients undergoing hemodialysis. © 2014 International Society for Hemodialysis.

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. © 2015 American Headache Society.

Rounding Behavior in the Reporting of Headache Frequency Complicates Headache Chronification Research

Objectives To characterize the extent of measurement error arising from rounding in headache frequency reporting (days per month) in a population sample of headache sufferers. Background When reporting numerical health information, individuals tend to round their estimates. The tendency to round to the nearest 5 days when reporting headache frequency can distort distributions and engender unreliability in frequency estimates in both clinical and research contexts. Methods This secondary analysis of the 2005 American Migraine Prevalence and Prevention study (AMPP) survey characterized the population distribution of 30-day headache frequency among community headache sufferers and determined the extent of numerical rounding (“heaping”) in self-reported data. Headache frequency distributions (days per month) were examined using a simplified version of Wang and Heitjan’s (2008) approach to heaping to estimate the probability that headache sufferers round to a multiple of 5 when providing frequency reports. Multiple imputation was used to estimate a theoretical “true” headache frequency. Results Of the 24,000 surveys, headache frequency data were available for 15,976 respondents diagnosed with migraine (68.6%), probable migraine (8.3%), or episodic tension-type headache (10.0%); the remainder had other headache types. The mean number of headaches days/month was 3.7 (SD = 5.6). Examination of the distribution of headache frequency reports revealed a disproportionate number of responses centered on multiples of 5 days. The odds that headache frequency was rounded to 5 increased by 24% with each one-day increase in headache frequency (OR: 1.24, 95% CI: 1.23 to 1.25), indicating that heaping occurs most commonly at higher headache frequencies. Women were more likely to round than men, and rounding decreased with increasing age and increased with symptoms of depression. Conclusions Because of the coarsening induced by rounding, caution should be used when

Evaluation of the Effect of Hemoglobin or Hematocrit Level on Dural Sinus Density Using Unenhanced Computed Tomography

Purpose To identify the relationship between hemoglobin (Hgb) or hematocrit (Hct) level and dural sinus density using unenhanced computed tomography (UECT). Materials and Methods Patients who were performed UECT and had records of a complete blood count within 24 hours from UECT were included (n=122). We measured the Hounsfield unit (HU) of the dural sinus at the right sigmoid sinus, left sigmoid sinus and 2 points of the superior sagittal sinus. Quantitative measurement of dural sinus density using the circle regions of interest (ROI) method was calculated as average ROI values at 3 or 4 points. Simple regression analysis was used to evaluate the correlation between mean HU and Hgb or mean HU and Hct. Results The mean densities of the dural sinuses ranged from 24.67 to 53.67 HU (mean, 43.28 HU). There was a strong correlation between mean density and Hgb level (r=0.832) and between mean density and Hct level (r=0.840). Conclusion Dural sinus density on UECT is closely related to Hgb and Hct levels. Therefore, the Hgb or Hct levels can be used to determine whether the dural sinus density is within the normal range or pathological conditions such as venous thrombosis. PMID:23225795

Central Action of Peripherally Applied Botulinum Toxin Type A on Pain and Dural Protein Extravasation in Rat Model of Trigeminal Neuropathy

Background Infraorbital nerve constriction (IoNC) is an experimental model of trigeminal neuropathy. We investigated if IoNC is accompanied by dural extravasation and if botulinum toxin type A (BoNT/A) can reduce pain and dural extravasation in this model. Methodology/Principal Findings Rats which developed mechanical allodynia 14 days after the IoNC were injected with BoNT/A (3.5 U/kg) into vibrissal pad. Allodynia was tested by von Frey filaments and dural extravasation was measured as colorimetric absorbance of Evans blue - plasma protein complexes. Presence of dural extravasation was also examined in orofacial formalin-induced pain. Unilateral IoNC, as well as formalin injection, produced bilateral dural extravasation. Single unilateral BoNT/A injection bilaterally reduced IoNC induced dural extravasation, as well as allodynia (lasting more than 2 weeks). Similarly, BoNT/A reduced formalin-induced pain and dural extravasation. Effects of BoNT/A on pain and dural extravasation in IoNC model were dependent on axonal transport through sensory neurons, as evidenced by colchicine injections (5 mM, 2 µl) into the trigeminal ganglion completely preventing BoNT/A effects. Conclusions/Significance Two different types of pain, IoNC and formalin, are accompanied by dural extravasation. The lasting effect of a unilateral injection of BoNT/A in experimental animals suggests that BoNT/A might have a long-term beneficial effect in craniofacial pain associated with dural neurogenic inflammation. Bilateral effects of BoNT/A and dependence on retrograde axonal transport suggest a central site of its action. PMID:22238656

Endovascular therapy with liquid embolic agents is a common treatment strategy for cranial dural arteriovenous fistulas. This study evaluated the long-term effectiveness of transarterial Onyx as the single embolic agent for curative embolization of noncavernous cranial dural arteriovenous fistulas. We performed a retrospective review of 40 consecutive patients with 41 cranial dural arteriovenous fistulas treated between March 2006 and June 2012 by using transarterial Onyx embolization with intent to cure. The mean age was 57 years; one-third presented with intracranial hemorrhage. Most (85%) had cortical venous drainage. Once angiographic cure was achieved, long-term treatment effectiveness was assessed with DSA and clinical follow-up. Forty-nine embolization sessions were performed; 85% of cranial dural arteriovenous fistulas were treated in a single session. The immediate angiographic cure rate was 95%. The permanent neurologic complication rate was 2% (mild facial palsy). Thirty-five of the 38 patients with initial cure underwent short-term follow-up DSA (median, 4 months). The short-term recurrence rate was only 6% (2/35). All patients with occlusion at short-term DSA undergoing long-term DSA (median, 28 months) had durable occlusion. No patient with long-term clinical follow-up (total, 117 patient-years; median, 45 months) experienced hemorrhage. Transarterial embolization with Onyx as the single embolic agent results in durable long-term cure of noncavernous cranial dural arteriovenous fistulas. Recurrence rates are low on short-term follow-up, and all patients with angiographic occlusion on short-term DSA follow-up have experienced a durable long-term cure. Thus, angiographic cure should be defined at short-term follow-up angiography instead of at the end of the final embolization session. Finally, long-term DSA follow-up may not be necessary if occlusion is demonstrated on short-term angiographic follow-up. © 2014 by American Journal of Neuroradiology.

New daily persistent headache (NDPH) is a chronic headache developing in a person who does not have a past history of headaches. The headache begins acutely and reaches its peak within 3 days. It is important to exclude secondary causes, particularly headaches due to alterations in cerebrospinal fluid (CSF) pressure and volume. A significant proportion of NDPH sufferers may have intractable headaches that are refractory to treatment. The condition is best viewed as a syndrome rather than a diagnosis. The headache can mimic chronic migraine and chronic tension-type headache, and it is also important to exclude secondary causes, particularly headaches due to alterations in CSF pressure and volume. A large proportion of NDPH sufferers have migrainous features to their headache and should be managed with treatments used for treating migraine. A small group of NDPH sufferers may have intractable headaches that are refractory to treatment.

Posterior fossa decompression surgeries for Chiari malformations are susceptible to postoperative complications such as pseudomeningocele, external cerebrospinal fluid (CSF) leak, and meningitis. Various dural substitutes have been used to improve surgical outcomes. This study examined whether the collagen matrix dural substitute type correlated with the incidence of postoperative complications after posterior fossa decompression in adult patients with Chiari I malformations. A retrospective cohort study was conducted of 81 adult patients who underwent an elective decompressive surgery for treatment of symptomatic Chiari I malformations, with duraplasty involving a dural substitute derived from either bovine or porcine collagen matrix. Demographics and treatment characteristics were correlated with surgical outcomes. A total of 81 patients were included in the study. Compared with bovine dural substitute, porcine dural substitute was associated with a significantly higher risk of pseudomeningocele occurrence (odds ratio, 5.78; 95% confidence interval, 1.65-27.15; P = 0.01) and a higher overall complication rate (odds ratio, 3.70; 95% confidence interval, 1.23-12.71; P = 0.03) by univariate analysis. There was no significant difference in the rate of meningitis, repeat operations, or overall complication rate between the 2 dural substitutes. In addition, estimated blood loss was a significant risk factor for meningitis (P = 0.03). Multivariate analyses again showed that porcine dural substitute was associated with pseudomeningocele occurrence, although the association with higher overall complication rate did not reach significance. Dural substitutes generated from porcine collagen, compared with those from bovine collagen, were associated with a higher likelihood of pseudomeningocele development in adult patients undergoing Chiari I malformation decompression and duraplasty.

To demonstrate the use of "Smart Puncture," a smartphone application to assist conventional CT-guided puncture without CT fluoroscopy, and to describe the advantages of this application. A puncture guideline is displayed by entering the angle into the application. Regardless of the angle at which the device is being held, the motion sensor ensures that the guideline is displayed at the appropriate angle with respect to gravity. The angle of the smartphone's liquid crystal display (LCD) is also detected, preventing needle deflection from the CT slice image. Physicians can perform the puncture procedure by advancing the needle using the guideline while the smartphone is placed adjacent to the patient. In an experimental puncture test using a sponge as a target, the target was punctured at 30°, 50°, and 70° when the device was tilted to 0°, 15°, 30°, and 45°, respectively. The punctured target was then imaged with a CT scan, and the puncture error was measured. The mean puncture error in the plane parallel to the LCD was less than 2°, irrespective of device tilt. The mean puncture error in the sagittal plane was less than 3° with no device tilt. However, the mean puncture error tended to increase when the tilt was increased. This application can transform a smartphone into a valuable tool that is capable of objectively and accurately assisting CT-guided puncture procedures.

Stafstrom, Carl E; Goldenholz, Shira R; Dulli, Douglas A

2005-10-01

Children's artistic self-depictions of headache provide valuable insights into their experience of pain and aid in the diagnostic differentiation of headache types. In a previous study, we compared the clinical diagnosis (gold standard) and artistic diagnosis of headaches in 226 children. In approximately 90% of cases, the drawing predicted the clinical diagnosis of migraine versus nonmigraine headache correctly. In the present study, we explored whether headache drawings correlate with clinical improvement after treatment in children with migraine headaches followed longitudinally. Children seen in the Pediatric Neurology Clinic with the chief complaint of headache were asked to draw a picture of what their headache feels like. On subsequent clinic visits, children with the clinical diagnosis of migraine were asked to draw another picture depicting their current headache. The two drawings were compared to assess whether there was improvement; this "artistic response" was then correlated with the child's clinical status (ie, whether the headaches were improved clinically). One hundred eleven children (66 girls, 45 boys) participated in the study, with a mean interval of 5.3 +/- 2.3 (standard error of the mean) months between the first and second visits. The mean age at the first visit was 11.6 +/- 3.1 years. The raters agreed that serial drawings were both improved or both not improved in 99 of the 111 cases (89%; interrater reliability kappa score of 0.767). Fifty-three children had improvements in their headaches and drawings, 3 children had an improved drawing but no clinical headache improvement, 32 children had no improvement in either their drawing or clinical headaches, and 11 children had improved headaches but no improvement in their drawing. The sensitivity of the drawings for clinical improvement was 0.83, and the specificity was 0.91. The predictive value of an improved headache drawing for an improved clinical response was 0.946.

Unusual headache syndromes.

PubMed

Queiroz, Luiz P

2013-01-01

Some headache syndromes have few cases reported in the literature. Their clinical characteristics, pathogenesis, and treatment may have not been completely defined. They may not actually be uncommon but rather under-recognized and/or underreported. A literature review of unusual headache syndromes, searching PubMed and ISI Web of Knowledge, was performed. After deciding which disorders to study, relevant publications in scientific journals, including original articles, reviews, meeting abstracts, and letters or correspondences to the editors were searched. This paper reviewed the clinical characteristics, the pathogenesis, the diagnosis, and the treatment of five interesting and unusual headache syndromes: exploding head syndrome, red ear syndrome, neck-tongue syndrome, nummular headache, and cardiac cephalgia. Recognizing some unusual headaches, either primary or secondary, may be a challenge for many non-headache specialist physicians. It is important to study them because the correct diagnosis may result in specific treatments that may improve the quality of life of these patients, and this can even be life saving. © 2013 American Headache Society.

Direct access to the middle meningeal artery for embolization of complex dural arteriovenous fistula: a hybrid treatment approach

PubMed Central

Lin, Ning; Brouillard, Adam M; Mokin, Maxim; Natarajan, Sabareesh K; Snyder, Kenneth V; Levy, Elad I; Siddiqui, Adnan H

2014-01-01

Endovascular embolization has become increasingly favored over microsurgical resection for treatment of complex dural arteriovenous fistulas (DAVFs). However, endovascular treatment can be restricted by tortuous transarterial access and a transvenous approach is not always feasible. We present a Borden III DAVF treated by direct access to the middle meningeal artery (MMA) and Onyx embolization performed in a hybrid operating room–angiography suite. A middle-aged patient with pulsatile headaches was found to have left transverse sinus occlusion and DAVF with retrograde cortical venous drainage fed by multiple external carotid artery (ECA) feeders. Endovascular attempts via conventional transvenous and transarterial routes were unsuccessful, and the major MMA feeder was accessed directly after temporal craniotomy was performed under neuronavigation. Onyx embolization was performed; complete occlusion of the fistula was achieved. Three-month follow-up angiography showed no residual filling; the patient remains complication-free. A combined surgical–endovascular technique in a hybrid operating room–angiography suite can be an effective treatment for DAVFs complicated by inaccessible arterial and transvenous approaches.

The management of cerebrospinal fluid (CSF) leaks can be challenging. Acellular dermal grafts derived from human cadavers can be used as a replacement material when autogenous materials are unavailable. Fibrin tissue adhesive (FTA) is a wound support product that has been used for hemostatic and tissue fixation purposes. The combined use of acellular dermis in conjunction with FTA for dural repair remains a subject of study. The aim of this study was to evaluate wound healing and tissue compatibility characteristics of acellular dermal substitute material when used both with and without FTA, for repair of a dural tear in a chinchilla model. Forty-nine chinchillas were included in this randomized case-control study. The squamous portion of the temporal bone was removed to expose the tegmen. A 2 x 2 mm dural defect was removed to create an iatrogenic CSF leak. Then, animals were randomly assigned to one of three treatment groups: group 1, acellular dermis alone; group 2, acellular dermis with FTA; group 3, fibrinogen, acellular dermis, and FTA. Surgical sites were examined grossly at 1- and 2-week intervals. Temporal bones were examined histologically. Grossly, groups 2 and 3 had significantly less visible CSF leak and brain herniation noted at both 1- and 2-week intervals when compared with group 1. Histological results confirmed the gross results showing the best seal in group 2 and 3. Acellular dermis combined with FTA provided superior support compared with acellular dermis alone in repair of induced dural defects.

The development of de novo dural arteriovenous fistula(s) following endovascular embolization of a prior high-flow pial arteriovenous fistula (PAVF) has not previously been reported and the natural history is unknown. The anatomic basis, pathophysiologic mechanism, management and outcome are discussed. Treatment-completed congenital PAVFs treated at our center between January 2005 and August 2011 were analyzed retrospectively. Among 16 cases of PAVFs treated by endovascular embolization, four developed de novo dural arteriovenous fistulas during treatment or on follow-up that were not present before treatment. Information was collected from the clinical case records, imaging by MRI on presentation and during follow-up, all angiographic images and records during each of the procedures and during follow-up. The time interval between the last embolization and identification of a dural fistula ranged from 3 to 14 months. Ten fistulas were identified in four patients, seven of which were embolized, four with glue, two with Onyx18 and one with absolute alcohol. None recanalized, while one patient developed fistula in an adjacent location that was subsequently treated with radiosurgery. Not all fistulas need treatment; small fistulas with a minimal flow can safely be observed. De novo dural fistulas following endovascular embolization of high-flow PAVFs is not an uncommon development. They are mostly asymptomatic and develop anywhere along the drainage of the fistula, maturing over time and diagnosed during follow-up studies, emphasizing the need for follow-up angiography. They can be effectively treated by endovascular embolization. Localized refractory dural fistulas can be dealt with by radiosurgery.

Prevalence of headache lowers with age, and headaches of elderly adults tend to be different than those of the younger population. Secondary headaches, such as headaches associated with vascular disease, head trauma, and neoplasm, are more common. Also, certain headache types tend to be geriatric disorders, such as primary cough headache, hypnic headache, typical aura without headache, exploding head syndrome, and giant cell arteritis. This review provides an overview of some of the major and unusual geriatric headaches, both primary and secondary.

Self-healing materials provide a route for enhanced damage tolerance in materials for aerospace applications. In particular, puncture-healing upon impact has the potential to mitigate significant damage caused by high velocity micrometeoroid impacts. This type of material also has the potential to improve damage tolerance in load bearing structures to enhance vehicle health and aircraft durability. The materials being studied are those capable of instantaneous puncture healing, providing a mechanism for mechanical property retention in lightweight structures. These systems have demonstrated healing capability following penetration of fast moving projectiles -- velocities that range from 9 mm bullets shot from a gun (approx.330 m/sec) to close to micrometeoroid debris velocities of 4800 m/sec. In this presentation, we report on a suite of polymeric materials possessing this characteristic. Figure 1 illustrates the puncture healing concept. Puncture healing in these materials is dependent upon how the combination of a polymer's viscoelastic properties responds to the energy input resulting from the puncture event. Projectile penetration increases the temperature in the vicinity of the impact. Self-healing behavior occurs following puncture, whereby energy must be transferred to the material during impact both elastically and inelastically, thus establishing two requirements for puncture healing to occur: a.) The need for the puncture event to produce a local melt state in the polymer material and b.) The molten material has to have sufficient melt elasticity to snap back and close the hole. 1,2 Previous ballistic testing studies revealed that Surlyn materials warmed up to a temperature approx.98 C during projectile puncture (3 C higher than it s melting temperature). 1,2 The temperature increase produces a localized flow state and the melt elasticity to snap back thus sealing the hole. Table 1 lists the commercially polymers studied here, together with their physical

Primary headaches--mainly tension-type headache and migraine--affect a significant portion of the population. Depression is also highly prevalent. The co-existence of a primary headache and depression in the same patient therefore might be a coincidence due to the high prevalence of these conditions, but there might be a causal relationship between them, or headaches and depression might have a common background. This review of the literature summarizes the features of the relationship between primary headaches and depression. Depression is more prevalent in headache patients than in the headache-free population. Prospective epidemiological studies suggest a common genetic, biochemical or environmental background behind primary headaches and depression. This theory is supported by the role of the same neurotransmitter systems (mostly serotonin and dopamine) in headaches as well as in depression. Comorbid depression is associated with female gender, higher age, and higher frequency of headaches. Most depression inventories--questionnaires used to screen for the severity of depressive symptoms--contain transdiagnostic items, therefore their use in their original form is limited in organic diseases: due to the somatic items they might overestimate the severity of depression. When examining a headache patient special attention should be paid to the recognition of comorbid depression. The diagnosis of suspected mood disorder could be supported by using simple screening methods, such as the original or the abbreviated versions of standard depression inventories, but the final diagnosis of major depression needs psychiatric evaluation. Quality of life of the headache patient is affected not only by the characteristics of pain (frequency, duration, severity) but also by the disability caused by headache and the associating mood disorder. Recognizing coexisting mood disorder and disability helps to make the best treatment choice for the acute and preventive treatment of

Tobacco, Nicotine, and Headache.

Migraineurs variably attribute the cause of their headache to tobacco exposure, whereas tobacco is often stated to cause headache-related disability worldwide. Given tobacco's physiological and emotional addictiveness and migraine's substantial economic impact, improved functionality can be difficult for those with migraine exposed to tobacco products. Environmental tobacco exposure in indoor spaces and workplaces is associated with exacerbation of headache. Avoidance of headache triggers is included in most comprehensive migraine treatment programs, yet tobacco awareness, avoidance, or coping is rarely emphasized as part of that regimen. The aims of this study were to examine the various types of tobacco products to which headache sufferers are exposed and the known basic mechanisms by which tobacco (nicotine) exposure promotes headache pain, and to review the extensive literature on tobacco related to headache with a detailed descriptive narrative providing the basis for conclusions regarding association of noncluster headache-related tobacco exposure. Tobacco-related recommendations are offered. MEDLINE, EMBASE, and Google Scholar databases were searched without yearly restriction through the date of submission (May 2015), using the MeSH terms "tobacco," "tobacco products," "smoking," "tobacco use," "headache," and "headache disorders." The selection of articles was not limited to English studies or to humans. Articles were excluded when "headache" and "tobacco" were not both mentioned with data provided. Case series were included. Bibliographies of all articles were screened for additional relevant articles. Although migraineurs worldwide report tobacco smoke among triggers, it is rarely among the highest in frequency, and biases abound with predominantly noncontrolled retrospective data. Prospective population-based diary data are extremely limited, and no controlled trials exist to confirm a cause and effect for headache of any type. Although some studies are

Chronic headache is still a frequent problem in old age, affecting about 10% of all women and 5% of all men older than 70 years. The incidence of primary headache decreases with advancing age, while that of secondary headache increases. The clinical characteristics of migraine can also change with age; for example, vegetative symptoms are less prominent, and less intense migrainous pain localized predominantly in the neck is frequently reported. Migraine aura can also be experienced more frequently in isolation, without a headache. Hypnic headache is a rare primary headache syndrome that occurs almost exclusively in the elderly. Most of the secondary headache syndromes that occur more frequently in old age present clinically as tension-type headache. Examples of rather common reasons for secondary headache syndromes in the elderly are intracranial space-occupying lesions, ophthalmological problems and autoimmune diseases such as giant cell arteritis. Elderly patients are especially likely to have a number of illnesses at any one time for which they take various medications each day, so that headaches can also quite often be caused by their medication or by withdrawal of these. As a result of such multimorbidity the homeostasis is disturbed in such patients, leading to various conditions that can entail concomitant headaches (sleep apnoea syndrome, dialysis headache, headache attributed to arterial hypertension or hypothyroidism). Familiar facial neuralgias, such as trigeminal neuralgia or postherpetic neuralgia following manifest herpes zoster affecting the face, become markedly more frequent with age. In general, in the treatment of headaches in the elderly it is essential to pay careful attention to potential interactions with the multiple drugs needed because of other diseases; in addition, the comorbidities themselves have to be taken into account, especially depression, anxiety and cognitive impairment, necessitating multimodal, interdisciplinary therapy plans.

Tension-Type Headache - The Normal and Most Prevalent Headache.

Jensen, Rigmor Højland

2018-02-01

Tension-type headache (TTH) is the most prevalent form of primary headache in the general population but paradoxically the least studied headache. In this article, the epidemiology and diagnostic challenges of TTH are presented and discussed. The typical features and differential diagnosis of TTH are highlighted and the situations more likely to raise doubts are discussed. A structured approach to the patient and a better comprehension of the very frequent coexistence of migraine and medication overuse headache in the clinical population are emphasized. According to the IHS classification, several diagnoses should be applied but still some clinicians prefer to apply a single combined diagnosis in the severely affected patients, namely chronic migraine. Such uneven practice may complicate the diagnostic comparability and the entire management of TTH. The present treatment strategies for TTH are summarized and hopefully an increased awareness of TTH can translate into better quality of care and a more specific diagnosis and treatment for the numerous TTH sufferers. © 2017 American Headache Society.

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.

Psychological Risk Factors in Headache

Headache is a chronic disease that occurs with varying frequency and results in varying levels of disability. To date, the majority of research and clinical focus has been on the role of biological factors in headache and headache-related disability. However, reliance on a purely biomedical model of headache does not account for all aspects of headache and associated disability. Using a biopsychosocial framework, the current manuscript expands the view of what factors influence headache by considering the role psychological (i.e., cognitive and affective) factors have in the development, course, and consequences of headache. The manuscript initially reviews evidence showing that neural circuits responsible for cognitive–affective phenomena are highly interconnected with the circuitry responsible for headache pain. The manuscript then reviews the influence cognitions (locus of control and self-efficacy) and negative affect (depression, anxiety, and anger) have on the development of headache attacks, perception of headache pain, adherence to prescribed treatment, headache treatment outcome, and headache-related disability. The manuscript concludes with a discussion of the clinical implications of considering psychological factors when treating headache. PMID:17371358

Dural arteriovenous fistulas as a cause of intracranial hypertension due to impairment of cranial venous outflow

PubMed Central

Cognard, C.; Casasco, A.; Toevi, M.; Houdart, E.; Chiras, J.; Merland, J.

1998-01-01

OBJECTIVES—A retrospective study was carried out on 13 patients with intracranial dural arteriovenous fistulas (DAVFs) who presented with isolated or associated signs of intracranial hypertension.
METHODS—Nine patients presented with symptoms of intracranial hypertension at the time of diagnosis. Ocular fundoscopy available in 12 patients showed bilateral papilloedema in eight and optic disk atrophy in four. Clinical evolution was particularly noticeable in five patients because of chronic (two patients) or acute (after lumbar shunting or puncture: three patients, one death) tonsillar herniation.
RESULTS—Two patients had a type I fistula (drainage into a sinus, with a normal antegrade flow direction). The remaining 11 had type II fistulas (drainage into a sinus, with abnormal retrograde venous drainage into sinuses or cortical veins). Stenosis or thrombosis of the sinus(es) distal to the fistula was present in five patients. The cerebral venous drainage was abnormal in all patients.
CONCLUSION—Type II (and some type I) DAVFs may present as isolated intracranial hypertension mimicking benign intracranial hypertension. Normal cerebral angiography should be added as a fifth criterion of benign intracranial hypertension. The cerebral venous drainage pattern must be carefully studied by contralateral carotid and vertebral artery injections to correctly evaluate the impairment of the cerebral venous outflow. Lumbar CSF diversion (puncture or shunting) may induce acute tonsillar herniation and should be avoided absolutely. DAVF may induce intracranial hypertension, which has a poor long term prognosis and may lead to an important loss of visual acuity and chronic tonsillar herniation. Consequently, patients with intracranial hypertension must be treated, even agressively, to obliterate the fistula or at least to reduce the arterial flow and to restore a normal cerebral venous drainage. The endovascular treatment may associate arterial or transvenous

Puncturing of aerosol cans is performed in the Waste Receiving and Processing Facility Module 1 (WRAP 1) process as a requirement of the waste disposal acceptance criteria for both transuranic (TRU) waste and low-level waste (LLW). These cans have contained such things as paints, lubricating oils, paint removers, insecticides, and cleaning supplies which were used in radioactive facilities. Due to Westinghouse Hanford Company (WHC) Fire Protection concerns of the baseline system`s fire/explosion proof characteristics, a study was undertaken to compare the baseline system`s design to commercially available puncturing devices. While the study found no areas which might indicate a riskmore » of fire or explosion, WHC Fire Protection determined that the puncturing system must have a demonstrated record of safe operation. This could be obtained either by testing the baseline design by an independent laboratory, or by substituting a commercially available device. As a result of these efforts, the commercially available Aerosolv can puncturing device was chosen to replace the baseline design. Two concerns were raised with the system. Premature blinding of the coalescing/carbon filter, due to its proximity to the puncture and draining operation; and overpressurization of the collection bottle due to its small volume and by blinding of the filter assembly. As a result of these concerns, testing was deemed necessary. The objective of this report is to outline test procedures for the Aerosolv.« less

New daily persistent headache (NDPH), which is the acute onset of headache within 3 days and is persistent for 15 days or more each month for at least 3 months, is a predominantly female heterogeneous subtype of chronic daily headache, typically with migraine features of unknown etiology. NDPH may be a presentation of other primary headaches such as new onset migraine, tension, or benign thunderclap headache. The headaches can be difficult to treat. The diagnosis is one of excluding the many secondary types or NDPH mimics, which is especially critical early in the course of the disease when a secondary etiology is more likely. NDPH mimics include postmeningitis headache, NDPH with medication rebound, neoplasms, temporal arteritis, chronic meningitis, chronic subdural hematoma, post-traumatic headaches, sphenoid sinusitis, hypertension, subarachnoid hemorrhage, low cerebrospinal fluid pressure syndrome, cervical artery dissections, pseudotumor cerebri without papilledema, and cerebral venous thrombosis.

The use of collagen matrix graft along with hydrogel dural sealant is a common method of IDT repair. With this method, there have been several reported cases of detrimental dural sealant expansion in the literature. One case study reported an expansion rate greater than 300%; many report neurologic damage. This article reports the clinical course of two patients who developed postoperative transcutaneous drainage of a gel-like substance after the use of a dural sealant, which is a previously unreported complication. Methods The clinical course and treatment outcome of two patients is presented. Results Both patients experienced postoperative transcutaneous drainage of a gel-like substance at the surgical site. Case one began draining this substance on postoperative day 14. This patient required no further intervention, and the drainage ended after 3 mL of a gel-like substance was expressed from his incision while in the clinic. Case two began draining the gel on postoperative day 16. This patient underwent two washout procedures and resolution of the drainage. No infection was ever detected. Conclusions To our knowledge, our patients are the first reported cases of transcutaneous drainage of expanded dural sealant. It is important to take into consideration the unexpected expansion of a dural sealant when using it for the repair of IDT.

Migraine is a highly prevalent chronic disorder associated with significant morbidity. Chronic daily headache syndromes, while less common, are less likely to be recognized, and impair quality of life to an even greater extent than episodic migraine. A variety of screening and diagnostic tools for migraine have been proposed and studied. Few investigators have developed and evaluated computerized programs to diagnose headache. To develop and determine the accuracy and utility of a computerized headache assessment tool (CHAT). CHAT was designed to identify all of the major primary headache disorders, distinguish daily from episodic types, and recognize medication overuse. CHAT was developed using an expert systems approach to headache diagnosis, with initial branch points determined by headache frequency and duration. Appropriate clinical criteria are presented relevant to brief and longer-lasting headaches. CHAT was posted on a web site using Microsoft active server pages and a SQL-server database server. A convenience sample of patients who presented to the adult urgent care department with headache, and patients in a family practice waiting room, were solicited to participate. Those who completed the on-line questionnaire were contacted for a diagnostic interview. One hundred thirty-five patients completed CHAT and 117 completed a diagnostic interview. CHAT correctly identified 35/35 (100%) patients with episodic migraine and 42/49 (85.7%) of patients with transformed migraine. CHAT also correctly identified 11/11 patients with chronic tension-type headache, 2/2 with episodic tension-type headache, and 1/1 with episodic cluster headache. Medication overuse was correctly recognized in 43/52 (82.7%). The most common misdiagnoses by CHAT were seen in patients with transformed migraine or new daily persistent headache. Fifty patients were referred to their primary care physician and 62 to the headache clinic. Of 29 patients referred to the PCP with a confirmed

Headache in essential thrombocythaemia

PubMed Central

Frewin, R; Dowson, A

2012-01-01

Headache is frequently reported as one of the neurological manifestations of essential thrombocythaemia (ET) and other myeloproliferative neoplasms. It is associated with considerable morbidity; yet, it is a frequently under-recognised symptom. In patients with ET, headaches may be attributable to the disease, to the prescribed ET treatment, or unrelated to ET. The majority of headaches in ET are self-limiting and can be managed with standard headache therapies such as paracetamol, but it is vital that the clinician managing these conditions is able to recognise the headaches with a more sinister pathology. In this article, we will review the incidence and management of headaches in ET, whether they are primarily related to the disease or a result of its treatment. Identification of specific headache types in patients with ET may enable physicians to employ the most effective headache medication. This would enhance the patient-physician relationship, increasing patient compliance and thus reducing the risk of adverse outcomes. PMID:22889110

Causality and headache triggers

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.

The purpose of this study was to evaluate the safety and efficacy of transorbital puncture for the retreatment of previously embolized cavernous sinus dural arteriovenous fistulas (DAVFs) via a superior ophthalmic vein (SOV) approach. During a 12-year period, 9 consecutive patients with previously embolized cavernous sinus DAVFs underwent retreatment via the transorbital SOV approach. All of the nine cases of previously embolized cavernous sinus DAVFs were successfully embolized. Clinical follow-ups were conducted in all nine cases at the duration of 17-141 months (61.22 ± 39.13 months). No recanalization occurred during the follow-up period. A subtle ptosis appeared in two patients and disappeared in one of the two cases after a 4-year follow-up. One patient suffered from paroxysmal positional vertigo and bruit for nearly 2 years after the treatment, but the follow-up angiography demonstrated no recurrence. One patient had persistent visual impairment caused by the initial venous stasis retinopathy. One patient with a history of a procedure-related transient decrease in visual acuity had it return to the normal level. The remaining four cases had clear improvement in the ocular symptoms and became completely asymptomatic during the follow-up period. No patient worsened or developed new symptoms. The approach of surgical cannulation of the SOV for the retreatment of previously embolized cavernous sinus DAVFs was proved feasible and efficient, especially when the transarterial and transfemoral venous approaches were inaccessible. However, if the SOV is not dilated enough or is located deeply in the orbit, transorbital venous puncture access may not be possible.

To investigate the sensitivity of MRI of the spine compared with CT myelography (CTM) in detecting CSF leaks. Between July 1998 and October 2010, 12 patients with orthostatic headache and a CTM-confirmed spinal CSF leak underwent an MRI of the spine with and without contrast. Using CTM as the gold standard, we retrospectively investigated the sensitivity of spinal MRI in detecting a CSF leak. Eleven of 12 patients with a CSF leak documented by CTM also had extradural fluid collections on spinal MRI (sensitivity 91.7%). Six patients with extradural fluid collections on spinal MRI also had spinal dural enhancement. When compared with the gold standard of CTM, MRI of the spine appears to be a sensitive and less invasive imaging modality for detecting a spinal CSF leak, suggesting that MRI of the spine should be the imaging modality of first choice for the detection of spinal CSF leaks.

Postdural puncture headache (PDPH) is a distressing complication of the subarachnoid block. The previous studies conducted, including the recent ones, do not conclusively prove that pencil-point spinal needles decrease the incidence of PDPH. In this study, we have tried to find out whether a pencil-point Whitacre needle is a better alternative than the classic cutting beveled, commonly used, Quincke spinal needle, in patients at risk of PDPH. Three hundred and twenty obstetric patients, 20-36 years of age, ASA I and II, posted for Cesarean section under subarachnoid block, were randomly assigned into two groups W and Q, where 25G Whitacre and 25G Quincke spinal needles were used, respectively. The primary objective of the study was to find out the difference in incidence of PDPH, if any, between the two groups, by using the t test and Chi square test. The incidence of PDPH was 5% in group W and 28.12% in group Q, and the difference in incidence was statistically significant (P<0.001). The pencil-point 25G Whitacre spinal needle causes less incidence of PDPH compared to the classic 25G Quincke needle, and is recommended for use in patients at risk of PDPH.

The primary objective of the study was to find out the difference in incidence of PDPH, if any, between the two groups, by using the t test and Chi square test. Results: The incidence of PDPH was 5% in group W and 28.12% in group Q, and the difference in incidence was statistically significant (P<0.001). Conclusion: The pencil-point 25G Whitacre spinal needle causes less incidence of PDPH compared to the classic 25G Quincke needle, and is recommended for use in patients at risk of PDPH.

A spinal dural arteriovenous fistula is an abnormally layered connection between radicular arteries and venous plexus of the spinal cord. This vascular condition is relatively rare with an incidence of 5-10 cases per million in the general population. Diagnosis of spinal dural arteriovenous fistula is differentiated by contrast-enhanced magnetic resonance angiography or structural magnetic resonance imaging, but a definitive diagnosis requires spinal angiography methods. Here, we report a case of a 67-year-old female with a spinal dural arteriovenous fistula, provide a pertinent clinical history to the case nosology, and discuss the biology of adhesive proteins, chemotactic molecules, and transcription factors that modify the behavior of the vasculature to possibly cause sensorimotor deficits.

The novel fish collagen scaffolds were prepared by lyophilization. The collagen sponges and chitosan were chemically cross-linked with the 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) as a cross-linking agent by pressing in one special mould. The collagen scaffolds were analyzed by scanning electron microscopy (SEM) and mechanical property, and the in vitro collagenase degradation was tested. The results revealed that the scaffold has a suitable porosity, elasticity and prevent fluid leakage, suggesting potential applications in the tissue-engineered. In vitro collagenase degradation demonstrated that the collagen cross-linking with EDC by pressing played an important role in their resistance to biodegradation. Moreover, the scaffold proved excellent biocompatibility for the activity and proliferation of mouse embryonic fibroblasts cells (MEFs) in vitro. The rabbit dural defect model demonstrated that the scaffolds could prevent brain tissue adhesion, which reduce the opportunity of inflammation, facilitate the growth of fibroblasts and enhance the tissue regeneration and healing. The novel fish collagen scaffold as dural substitute, demonstrate a capability for using in the field of tissue engineering. Copyright © 2017. Published by Elsevier B.V.

Epigenetic changes in headache.

2017-12-23

Multiple factors, including both genetic and environmental mechanisms, appear to play a role in the aetiology of headache. An interesting area of study is the possible involvement of epigenetic mechanisms in headache development and the transformation to chronic headache, and the potential role of these factors as a therapeutic target. We performed a literature review of the involvement of different epigenetic mechanisms in headache, mainly using the Medline/PubMed database. To this end, we used the following English search terms: headache, migraine, epigenetics, DNA methylation, histones, non-coding RNA, and miRNA. A total of 15 English-language publications related to the above terms were obtained. There is limited but consistent evidence of the relationship between epigenetics and headache; it is therefore essential to continue research of epigenetic changes in headache. This may help to understand the pathophysiology of headache and even to identify candidate biomarkers and new, more effective, therapeutic targets. Copyright © 2017 Sociedad Española de Neurología.

Neuromodulation of chronic headaches: position statement from the European Headache Federation

PubMed Central

2013-01-01

The medical treatment of patients with chronic primary headache syndromes (chronic migraine, chronic tension-type headache, chronic cluster headache, hemicrania continua) is challenging as serious side effects frequently complicate the course of medical treatment and some patients may be even medically intractable. When a definitive lack of responsiveness to conservative treatments is ascertained and medication overuse headache is excluded, neuromodulation options can be considered in selected cases. Here, the various invasive and non-invasive approaches, such as hypothalamic deep brain stimulation, occipital nerve stimulation, stimulation of sphenopalatine ganglion, cervical spinal cord stimulation, vagus nerve stimulation, transcranial direct current stimulation, repetitive transcranial magnetic stimulation, and transcutaneous electrical nerve stimulation are extensively published although proper RCT-based evidence is limited. The European Headache Federation herewith provides a consensus statement on the clinical use of neuromodulation in headache, based on theoretical background, clinical data, and side effect of each method. This international consensus further gives recommendations for future studies on these new approaches. In spite of a growing field of stimulation devices in headaches treatment, further controlled studies to validate, strengthen and disseminate the use of neurostimulation are clearly warranted. Consequently, until these data are available any neurostimulation device should only be used in patients with medically intractable syndromes from tertiary headache centers either as part of a valid study or have shown to be effective in such controlled studies with an acceptable side effect profile.

The objective of this series is to examine several threats to the interpretation of headache chronification studies that arise from methodological issues. The study of headache chronification has extensively used longitudinal designs with two or more measurement occasions. Unfortunately, application of these designs when combined with the common practice of extreme score selection as well as the extant challenges in measuring headache frequency rates (eg, unreliability, regression to the mean), induces substantive threats to accurate interpretation of findings. Partitioning the amount of observed variance in rates of chronification and remission attributable to regression artifacts is a critical yet previously overlooked step to learning more about headache as a potentially progressive disease. In this series on rethinking headache chronification, we provide an overview of methodological issues in this area (this paper), highlight the influence of rounding error on estimates of headache frequency (second paper), examine the influence of random error and regression artifacts on estimates of chronification and remission (third paper), and consider future directions for this line of research (fourth paper).

Object Symptomatic pediatric Chiari malformation Type I (CM-I) is most often treated with posterior fossa decompression (PFD), but controversy exists over whether the dura needs to be opened during PFD. While dural opening as a part of PFD has been suggested to result in a higher rate of resolution of CM symptoms, it has also been shown to lead to more frequent complications. In this paper, the authors present the largest reported series of outcomes after PFD without dural opening surgery, as well as identify risk factors for recurrence. Methods The authors performed a retrospective review of 156 consecutive pediatric patients in whom the senior authors performed PFD without dural opening from 2003 to 2013. Patient demographics, clinical symptoms and signs, radiographic findings, intraoperative ultrasound results, and neuromonitoring findings were reviewed. Univariate and multivariate regression analyses were performed to determine risk factors for recurrence of symptoms and the need for reoperation. Results Over 90% of patients had a good clinical outcome, with improvement or resolution of their symptoms at last follow-up (mean 32 months). There were no major complications. The mean length of hospital stay was 2.0 days. In a multivariate regression model, partial C-2 laminectomy was an independent risk factor associated with reoperation (p = 0.037). Motor weakness on presentation was also associated with reoperation but only with trend-level significance (p = 0.075). No patient with < 8 mm of tonsillar herniation required reoperation. Conclusions The vast majority (> 90%) of children with symptomatic CM-I will have improvement or resolution of symptoms after a PFD without dural opening. A non–dural opening approach avoids major complications. While no patient with tonsillar herniation < 8 mm required reoperation, children with tonsillar herniation at or below C-2 have a higher risk for failure when this approach is used. PMID:25932779

Headache in children's drawings.

Headache is a common health problem in childhood. Children's drawings are helpful in the diagnosis of headache type. Children, especially younger ones, communicate better through pictures than verbally. The aim of the present study is to evaluate the usefulness of drawings of the child's headache in the diagnostic process carried out by a pediatrician and a pediatric neurologist. At the beginning of a visit in a neurological clinic, or on the first day of hospitalization, the child was asked, "Please draw your headache," or "How do you feel your headache?" without any additional explanations or suggestions. Clinical diagnosis of headache type was made on the basis of the standard diagnostic evaluation. For the purpose of this study, children's headaches were categorized as migraine, tension-type headache, or "the others." One hundred twenty-four drawings of children with headaches were analyzed by 8 pediatricians and 8 pediatric neurologists. The analysts were unaware of the clinical history, age, sex, and diagnosis of the patients. The clinical diagnosis was considered the "gold standard" to which the headache drawing diagnosis was compared. There were 68 girls 5-18 years of age and 56 boys 7-18 years of age. Of the 124 children, 40 were clinically diagnosed with migraine (32.2%), 47 with tension-type headache (37.9%), and 37 (29.8%) as the others. Children with migraine most frequently draw sharp elements. Children with tension-type headache mainly drew compression elements and pressing elements. In the group of "the other" headaches, 21 children were diagnosed with somatoform disorders. The most frequent element in this group's drawings was a whirl in the head. Colors used most frequently were black and red, which signify severe pain. There was no difference in sensitivity of diagnoses between neurologists and pediatricians. Because the evaluation of drawings by children with headaches done both by pediatricians and pediatric neurologists was correct for

The objective of this study is to evaluate the efficacy and safety of non-suture dural closure using a novel dural substitute (GM111) consisting of polyglycolic acid felt with a fibrin-glue-coated area commensurate in size with the dural defect. This was a non-controlled, open-label, multicenter clinical trial. The efficacy evaluation endpoints were (1) GM111's intra-operative capability to close dural defects and (2) prevention of cerebrospinal fluid (CSF) leakage and subcutaneous CSF retention throughout the postoperative period (evaluated by diagnostic imaging). Patients meeting the following three preoperative and two intra-operative selection criteria were enrolled: (1) between 12 and <75 years of age; (2) the dura is surmised to be defective and in need of reconstruction; (3) informed written consent was obtained from the patient; (4) the surgical wound is class 1; and (5) the size of duraplasty is ≥0.2 cm 2 to <100 cm 2 . Sixty patients were enrolled. The craniotomy site was supratentorial in 77.2%, infratentorial in 12.3% and sellar in 10.5%. The GM111 prosthesis size ranged from 0.24 to 42 cm 2 . To evaluate the efficacy, intra-operative closure was confirmed by Valsalva's maneuver, water infusion, etc., in all patients. CSF leakage and subcutaneous CSF retention throughout the postoperative period were found in four patients. Adverse events for which a causal relationship with GM111 could not be ruled out occurred in 8.8% of the patients. There were no instances of postoperative infection due to GM111. GM111 showed good closure capability and safety when used for non-suture dural closure.

Quantitative Susceptibility Mapping as a Possible Tool to Radiographically Diagnose Sentinel Headache Associated with Intracranial Aneurysm: Case Report.

Sentinel headache (SH) occurs before aneurysm rupture in an estimated 15%-60% of cases of aneurysmal subarachnoid hemorrhage (aSAH). By definition, noncontrast computed tomography (CT) scan of the brain and lumbar puncture are both negative in patients presenting with SH. One of the theories explaining this phenomenon is that microhemorrhage (MH) from the aneurysm wall contribute to iron deposition in the interface between the aneurysm wall and brain parenchyma. Quantitative susceptibility mapping (QSM) is a recently introduced magnetic resonance imaging (MRI) technique that has proven capable of localizing the deposition of paramagnetic metals, particularly ferric iron. Thus, the QSM sequence may be able to detect iron deposition secondary to MH. A 76-year-old male presented with the "worst headache of my life." Noncontrast head CT scan and lumbar puncture were negative. Magnetic resonance angiography (MRA) of the brain revealed an anterior communicating artery (A-com) aneurysm measuring 7 mm with a large bleb. T1-weighted imaging (WI), T2-WI, MRA, T2 star-weighted angiography (SWAN), and QSM sequences were obtained. T2-WI, SWAN, and QSM revealed isointense, hypointense, and hyperintense signals, respectively, at the interface of the aneurysm wall and brain tissue. These findings were consistent with deposition of ferric iron at this interface. The A-com aneurysm was treated with coil embolization, and the patient exhibited no postoperative deficits. The MRI QSM sequence can localize iron deposition resulting from MH within an aneurysmal wall. This sequence may be a promising imaging tool for screening patients presenting with SH.

A history of non-drug treatment in headache, particularly migraine.

PubMed

Koehler, Peter J; Boes, Christopher J

2010-08-01

Although new invasive procedures for the treatment of migraine have evolved during the past decades, the application of invasive procedures for this indication is not new. In this review, the history of non-drug treatments for migraine is discussed. Historical texts by physicians known to have written on headache and migraine (hemicrania), well-known books by physicians from the main historical periods up to 1900 and mainstream 20th century neurology handbooks were analysed. A large number of treatments have been tried, based on contemporaneous pathophysiological models that were not only applied to headache, but to medicine in general. Invasive procedures have been used for the more severe types of headache. Many treatments were based on ancient humoral theories up to the early 19th century. A new kind of invasive procedure appeared on the physician's palette in the 19th and 20th century, following the development of new ideas that were based on solid pathophysiology, after the introduction of scientific method into medicine. After its introduction in the mid-18th century, medical electricity became even more popular for the treatment of migraine following the discovery of vasomotor nerves in the mid-19th century, but at the end of that century a more critical attitude appeared. The discovery of the lumbar puncture (1892) and roentgenogram (1895) and increased knowledge of intracranial pressure led to a new series of invasive procedures for therapy-resistant migraine in the early 20th century. Vasospastic theories of migraine led to surgical procedures on the sympathetic nerves. Following the experiments by Graham and Wolff in the 1930s that emphasized the vasodilatation concept of migraine, sympathicolytic procedures again became popular, including vessel ligation of the carotid and middle meningeal arteries. The influence of suggestion and psychological phenomena recognized at the end of the 19th century probably played an important role in many of the

The objective of this study was to describe demographic and clinical characteristics including features that were consistent with subarachnoid hemorrhage (SAH), use of diagnostic tests, emergency department (ED) discharge diagnoses, and disposition of adult patients presenting with an acute headache to EDs statewide across Queensland, Australia. In addition, potential variations in the presentation and diagnostic workup between principal-referral and city-regional hospitals were examined. A prospective cross-sectional study was conducted over 4 weeks in September 2014. All patients ≥ 18 years presenting to one of 29 public and five private hospital EDs across the state with an acute headache were included. The headache had to be the principal presenting complaint and nontraumatic. The 34 study sites attend to about 90% of all ED presentations statewide. The treating doctor collected clinical information at the time of the ED visit including the characteristics of the headache and investigations performed. A study coordinator retrieved results of investigations, ED discharge diagnoses, and disposition from state databases. Variations in presentation, investigations, and diagnosis between city-regional and principal-referral hospitals were examined. There were 847 headache presentations. Median (range) age was 39 (18-92) years, 62% were female, and 31% arrived by ambulance. Headache peaked instantly in 18% and ≤ 1 hour in 44%. It was "worst ever" in 37%, 10/10 in severity in 23%, and associated with physical activity in 7.4%. Glasgow Coma Scale score was < 15 in 4.1%. Neck stiffness was noted on examination in 4.8%. Neurologic deficit persisting in the ED was found in 6.5%. A computed tomography (CT) head scan was performed in 38% (318/841, 95% CI = 35% to 41%) and an lumbar puncture in 4.7% (39/832, 95% CI = 3.4% to 6.3%). There were 18 SAH, six intraparenchymal hemorrhages, one subdural hematoma, one newly diagnosed brain metastasis, and two bacterial

Dementia is a chronic loss of neurocognitive function that is progressive and irreversible. Although rare, dural arteriovenous fistulas (DAVFs) could present with a rapid decline in neurocognitive function with or without Parkinson-like symptoms. DAVFs represent a potentially treatable and reversible cause of dementia. Here, we report the case of an elderly woman diagnosed with a DAVF after presenting with new-onset seizures, deteriorating neurocognitive function, and Parkinson-like symptoms.

Dural repair products are evolving from animal tissue-derived materials to synthetic materials as well as from inert to absorbable features; most of them lack functional and structural characteristics compared with the natural dura mater. In the present study, we evaluated the properties and tissue repair performance of a new dural repair product with biomimetic design. The biomimetic patch exhibits unique three-dimensional nonwoven microfiber structure with good mechanical strength and biocompatibility. The animal study showed that the biomimetic patch and commercially synthetic material group presented new subdural regeneration at 90 days, with low level inflammatory response and minimal to no adhesion formation detected at each stage. In the biological material group, no new subdural regeneration was observed and severe adhesion between the implant and the cortex occurred at each stage. In clinical case study, there was no cerebrospinal fluid leakage, and all the postoperation observations were normal. The biomimetic structure and proper rate of degradation of the new absorbable dura substitute can guide the meaningful reconstruction of the dura mater, which may provide a novel approach for dural defect repair.

We propose a double layered (intradural and epidural patch) duraplasty that utilizes Lyoplant and Duraseal. We examined a 47-year-old woman after decompression for thoracic ossification of posterior longitudinal ligament was performed in another hospital. On postoperative day 7, she complained of weakness in both legs. Postoperative magnetic resonance imaging (MRI) showed cerebrospinal fluid (CSF) collection with cord compression. In the operative field, we found 2 large dural defects on the ventral dura mater. We performed a conventional fat graft with fibrin glue. However, the patient exhibited neurologic deterioration, and a postoperative MRI again showed CSF collection. We performed dorsal midline durotomy and inserted a intradural and epidural Lyoplant patch. She immediately experienced diminishing back pain postoperatively. Her visual analog scale and motor power improved markedly. Postoperative MRIs performed at 2 and 16 months showed no spinal cord compression or CSF leakage to the epidural space. We describe a new technique for double layered duraplasty. Although we do not recommend this technique for all dural repairs, double-layered duraplasty may be useful for repairing large inaccessible dural tears in cases of persistent CSF leakage refractory to conventional management.

2010-01-01

A 4-month-old boy presented with the sudden onset of proptosis and dilated episcleral veins. CT revealed an enlarged superior ophthalmic vein and diffusely thickened extraocular muscles. MRI and angiography confirmed a dural middle meningeal--cavernous sinus fistula. Embolization was performed leading to successful resolution of the patient's signs and symptoms. Spontaneous atraumatic arteriovenous cavernous fistulae in infancy are extremely rare, but should be included in the differential diagnosis of infants with orbital congestion. Appropriate treatment leads to prevention of amblyopia, glaucoma, and anisometropia.

Background Intracranial dural arteriovenous fistulae (DAVF) may present a treatment challenge. Endovascular embolization is in most cases the first line of treatment but does not always achieve cure. Gamma Knife (GK) radiosurgery represents an alternative treatment option, and the purpose of this study was to further evaluate its utility. Methods We reviewed all cases of DAVF treated between 2009 and 2016 at our institution with GK radiosurgery independently, or following failed/refused endovascular or surgical management. Patients’ clinical files, radiological images, catheter angiograms, and surgical DAVF disconnection reports were retrospectively reviewed. Results Sixteen DAVF (14 patients) treated by GK radiosurgery were identified. Eleven fistulae were aggressive and five were benign. Marginal doses ranged from 15 to 25 Gy. Target volumes ranged from 0.04 to 4.47 cm3. In all symptomatic patients, GK treatment resulted in symptom palliation. In 13/15 lesions, cure of symptoms (86.0%) was reported. One lesion was asymptomatic. Angiographic cure was achieved in eight cases (50%), small residual DAVF occurred in four, and four were unchanged. One patient developed headache that resolved at one year. No hemorrhage occurred during the follow-up period. There was no significant association between Borden type and cure rate. Prior failed endovascular treatment and small target volume were associated with lower rates of cure. Conclusions Stereotactic radiosurgery is viable treatment for DAVF. It is very effective in palliating symptoms as a de novo approach or adjunctive to endovascular therapy. In our experience it is only somewhat effective in achieving complete angiographic cure.

Disadvantages of fluoroscopically guided lumbar puncture include delivery of ionizing radiation and limited resolution of incompletely ossified posterior elements. Ultrasound (US) allows visualization of critical soft tissues and the cerebrospinal fluid (CSF) space without ionizing radiation. To determine the technical success and safety of US-guided lumbar puncture in pediatric patients. A retrospective review identified all patients referred to interventional radiology for lumbar puncture between June 2010 and June 2017. Patients who underwent lumbar puncture with fluoroscopic guidance alone were excluded. For the remaining procedures, technical success and procedural complications were assessed. Two hundred and one image-guided lumbar punctures in 161 patients were included. Eighty patients (43%) had previously failed landmark-based attempts. One hundred ninety-six (97.5%) patients underwent lumbar puncture. Five procedures (2.5%) were not attempted after US assessment, either due to a paucity of CSF or unsafe window for needle placement. Technical success was achieved in 187 (95.4%) of lumbar punctures attempted with US guidance. One hundred seventy-seven (90.3%) were technically successful with US alone (age range: 2 days-15 years, weight range: 1.9-53.1 kg) and an additional 10 (5.1%) were successful with US-guided thecal access and subsequent fluoroscopic confirmation. Three (1.5%) cases were unsuccessful with US guidance but were subsequently successful with fluoroscopic guidance. Of the 80 previously failed landmark-based lumbar punctures, 77 (96.3%) were successful with US guidance alone. There were no reported complications. US guidance is safe and effective for lumbar punctures and has specific advantages over fluoroscopy in pediatric patients.

Migraines occur within certain time frames. Nevertheless, information regarding circadian variation in the clinical presentation of migraine is limited. We investigated circadian variations in the clinical presentation of migraine using a smartphone headache diary (SHD). We enrolled adult participants with the diagnosis of migraine according to the third beta edition of the International Classification of Headache Disorders. Participants were asked to log in to the SHD every day for 90 days to record the occurrence of headaches. We compared the occurrence and clinical presentation of headaches during four 6-hour quadrants per day (00:00-05:59, 06:00-11:59, 12:00-17:59, and 18:00-23:59). Migraine-type headache was defined as a headache attack that fulfilled all criteria of migraine, except for the criterion regarding typical headache duration. Eighty-two participants kept a dairy for at least 50% of the study period and recorded 1491 headache attacks. Among the 1491 headache attacks, 474 (31.8%) were classified as migraine-type headaches and 1017 (68.2%) were classified as non-migraine-type headaches. All headaches, migraine-type headaches and non-migraine-type headaches occurred most frequently between 06:00 and 11:59, and least frequently between 18:00 and 23:59, and between 00:00 and 05:59. Migrainous headache characteristics, such as unilateral pain, pulsating quality, severe headache intensity, aggravation by movement, nausea, photophobia, and phonophobia presented most frequently between 06:00 and 11:59, and least frequently between 18:00 and 23:59, and 00:00 and 05:59 among 1491 all headache attacks. Headache clinical presentation as well as headache occurrence exhibited circadian periodicity among migraineurs.

ABSTRACT Purpose: To evaluate the efficiency of a novel device coupled with ultrassound for renal percutaneous puncture. Materials and Methods: After establishing hydronephrosis, ten pigs had three calyxes of each kidney punctured by the same urology resident, with and without the new device (“Punctiometer”). Time for procedure completion, number of attempts to reach the calyx, puncture precision and puncture complications were recorded in both groups and compared. Results: Puncture success on the first attempt was achieved in 25 punctures (83%) with the Punctiometer and in 13 punctures (43%) without the Punctiometer (p=0.011). The mean time required to perform three punctures in each kidney was 14.5 minutes with the Punctiometer and 22.4 minutes without the Punctiometer (p=0.025). The only complications noted were renal hematomas. In the Punctiometer group, all kidneys had small hematomas. In the no Punctiometer group 80% had small hematomas, 10% had a medium hematoma and 10% had a big hematoma. There was no difference in complications between both groups. Conclusions: The Punctiometer is an effective device to increase the likelihood of an accurate renal calyx puncture during PCNL, with a shorter time required to perform the procedure. PMID:26689521

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.

To quantify physician stress levels when performing lumbar puncture (LP) and explore operator stress effect on patient outcomes. This was a cross-sectional, multicenter study. Novices, intermediates, and experts in performing LP were recruited from 4 departments of neurology and emergency medicine. Stress was measured before and during performance of the LP using cognitive appraisal (CA), State-Trait Anxiety Inventory-Short (STAI-S) questionnaire, and the heart rate variability measure low frequency/high frequency index (LF/HF ratio). Patient-related outcomes were pain, confidence in the operator, and postdural puncture headache (PDPH). Forty-six physicians were included in the study: 22 novices, 12 intermediates, and 12 experts. Novices had the highest stress level and experts the lowest measured by cognitive appraisal and STAI-S before and during LP performance ( p < 0.001 for all comparisons). Novices had the highest sympathetic tonus indicated by the highest LF/HF ratio before ( p = 0.004) and during ( p = 0.056) LP performance. Physician stress level was not significantly related to patients' pain. However, there was a significant relationship between STAI-S during the procedure and patient confidence in the operator (regression coefficient = -0.034, p = 0.008). High physician heart rate during the procedure significantly increased the odds of PDPH (odds ratio = 1.17, p = 0.036). Novice stress levels were high before and during performance of LP. Stress was significantly related to patient confidence in the operator and risk of PDPH. Simulation-based training should be considered to reduce novice residents' stress levels and increase patient safety. © 2018 American Academy of Neurology.

 The objective of this study was to investigate frequency and trends of skin punctures in preterm infants.  A prospective audit of preterm infants less than 35 weeks admitted over a 6-month period to a tertiary neonatal intensive care unit. Each skin puncture performed in the first 2 weeks of life was documented in a specifically designed audit sheet.  Ninety-nine preterm infants were enrolled. Infants born at < 32 weeks' gestation had significantly more skin punctures than infants > 32 weeks (median skin punctures 26.5 vs. 17, p -value < 0.05). The highest frequency of skin punctures occurred during the first week of life for infants > 28 weeks' gestation (medians 17.5 in 28-31 + 6 weeks' gestation, and 15 in > 32 weeks), and during the second week of life for those born at < 28 weeks (median 17.5). Infants with sepsis had more skin punctures ( p -value < 0.001), but this was not significant on multivariate analysis. Median skin punctures in the second week of life were statistically higher in the sepsis group on multivariate analysis (odds ratio: 1.07, 95% confidence interval: 1.00-1.14, p  = 0.041).  Frequency of skin punctures is influenced by gestational age and postnatal age. Skin punctures were not an independent risk factor for sepsis. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

To evaluate the utility of the hybrid tracheoesophageal puncture procedure in stapler-assisted laryngectomy. Patients who underwent total laryngectomy at a single institution from 2009 to 2015 were reviewed. The interventions assessed were surgical creation of a tracheoesophageal puncture and placement of a voice prosthesis. The outcomes measured included voicing ability and valve failure. Thirty-nine patients underwent total laryngectomy or pharyngolaryngectomy. Of these, nine underwent stapler-assisted laryngectomy; seven of the nine patients underwent concurrent stapler-assisted laryngectomy, cricopharyngeal myotomy and a hybrid tracheoesophageal puncture procedure. These seven patients were the focus of this review. Successful voicing and oral alimentation was achieved in all patients. Mean time to phonation was 30 days (range, 7-77 days) and mean time to first valve change was 90 days (range, 35-117 days). Primary tracheoesophageal puncture with concurrent voice prosthesis placement and cricopharyngeal myotomy is easily performed with stapler-assisted laryngectomy. The hybrid tracheoesophageal puncture procedure is a simple method that enables a single operator to achieve primary tracheoesophageal puncture and valve placement; in addition, it facilitates concurrent cricopharyngeal myotomy.

The two most important representatives of the primary headaches are migraine and tension-type headache. More than 10% of the population suffer from migraine and even a greater part, approximately 30-40% from tension-type headache. These two headache types have a great effect both on the individual and on the society. There are two types of therapeutic approaches to headaches: the abortive and the prophylactic therapy. Prophylactic treatment is used for frequent and/or difficult-to-treat headache attacks. Although both migraine and tension-type headache are often associated with depression, for their treatment - in contrast to the widespread medical opinion - not all antidepressants were found to be effective. Amitriptyline, which is a tricyclic antidepressant, is used as a prophylactic therapy for headache since 1968. Its efficacy has been demonstrated in several double-blind, placebo-controlled studies. Although the newer types of antidepressant, such as selective serotonin reuptake inhibitors and selective serotonin-norepinephrine reuptake inhibitor, have a more favorable side-effect profile than tricyclic antidepressants, their headache prophylactic effect has not been proven yet.

Headache is one of the most common conditions presenting to the neurology clinic, yet a significant proportion of these patients are unsatisfied by their clinic experience. Headache can be extremely disabling; effective treatment is not only essential for patients but is rewarding for the physician.

The objective of this study was to compare the headache impact test (HIT-6) and the migraine disability assessment scale (MIDAS) as clinical measures of headache-related disability. The degree of headache-related disability is an important factor in treatment planning. Many quality of life and headache disability measures exist but it is unclear which of the available disability measures is the most helpful in planning and measuring headache management. We compared HIT-6 and MIDAS scores from 798 patients from the Canadian Headache Outpatient Registry and Database (CHORD). Correlation and regression analyses were used to examine the relationships between the HIT-6 and MIDAS total scores, headache frequency and intensity, and Beck Depression Inventory (BDI-II) scores. A positive correlation was found between HIT-6 and MIDAS scores (r = 0.52). The BDI-II scores correlated equally with the HIT-6 and the MIDAS (r = 0.42). There was a non-monotonic relationship between headache frequency and the MIDAS, and a non-linear monotonic relationship between headache frequency and the HIT-6 (r = 0.24). The correlation was higher between the intensity and the HIT-6 scores (r = 0.46), than MIDAS (r = 0.26) scores. Seventy-nine percent of patients fell into the most severe HIT-6 disability category, compared with the 57% of patients that fell into the most severe MIDAS disability category. Significantly more patients were placed in a more severe category with the HIT-6 than with the MIDAS (McNemar chi-square = 191 on 6 d.f., P < .0001). The HIT-6 and MIDAS appear to measure headache-related disability in a similar fashion. However, some important differences may exist. Headache intensity appears to influence HIT-6 score more than the MIDAS, whereas the MIDAS was influenced more by headache frequency. Using the HIT-6 and MIDAS together may give a more accurate assessment of a patient's headache-related disability.

Cranial dural arteriovenous fistulae have been classified into high- and low-risk lesions mainly based on the pattern of venous drainage. Those with leptomeningeal venous drainage carry a higher risk of an aggressive clinical presentation. Recently, it has been proposed that the clinical presentation should be considered as an additional independent factor determining the clinical course of these lesions. However, dural shunts with leptomeningeal venous drainage include a very wide spectrum of inhomogeneous lesions. In the current study, we correlated the clinical presentation of 107 consecutive patients harboring cranial dural arteriovenous shunts with leptomeningeal venous drainage, with their distinct anatomic and angiographic features categorized into eight groups based on the "DES" (Directness and Exclusivity of leptomeningeal venous drainage and features of venous Strain) concept. We found that among these groups, there are significant angioarchitectural differences, which are reflected by considerable differences in clinical presentation. Leptomeningeal venous drainage of dural sinus shunts that is neither direct nor exclusive and without venous strain manifested only benign symptoms (aggressive presentation 0%). On the other end of the spectrum, the bridging vein shunts with direct and exclusive leptomeningeal venous drainage and venous strain are expected to present aggressive symptoms almost always and most likely with bleeding (aggressive presentation 91.5%). Important aspects of the above correlations are discussed. Therefore, the consideration of leptomeningeal venous drainage alone, for prediction of the clinical presentation of these shunts appears insufficient. Angiographic analysis based on the above concept, offers the possibility to distinguish the higher- from the lower-risk types of leptomeningeal venous drainage. In this context, consideration of the clinical presentation as an additional independent factor for the prediction of their clinical

Two prior studies have shown an increased prevalence of migraine among physicians who are headache medicine specialists (HMS). There have been no studies of the prevalence of other headache disorders among HMS. A prior survey showed that neurologists like to treat some headaches more than others but there has not been a similar survey of HMS. The aim of the survey was to learn more about the prevalence of headaches among HMS and which headache disorders they like to treat. An email survey was sent to 749 physician members of the American Headache Society who were asked to respond to the following statement using a 5-point Likert scale (from 1, strongly disagree to 5, strongly agree): "I like to treat patients with the following types of headaches or syndromes." They were asked, "Have you personally suffered from any of the following at any time during your life: episodic migraine (EM), chronic migraine (CM), refractory migraine (RM), episodic cluster (EC), chronic cluster (CC), new daily persistent headache (NDPH), and postconcussion syndrome (PCS)." The response rate was 15.8% (n = 118) with a mean age of 51.4 years, 64.4% males, and 85.6% neurologists. HMS reported likeability for treating disorders in rank order as follows: EM (mean = 4.69, SD = 0.61); CM (mean = 4.20, SD = 0.94); RM (mean = 3.62, SD = 1.17); EC (mean = 4.37, SD = 0.80); CC (mean = 3.68, SD = 1.10); NDPH (mean = 3.52, SD = 1.21); and PCS (mean = 3.66, SD = 1.18). The lifetime prevalence of disorders was as follows: EM, 69.5% (85.7% in females and 60.5% in males); CM, 13.6% (19% in females and 10.5% in males); RM, .9% (2.4% females and 0% males); EC, 1.7% (0% females and 2.6% males); CC, 0%; NDPH, 0%, and PCS, 4.2% (7.1% females and 2.6% males).

To determine the extent to which variation in the Migraine Disability Assessment (MIDAS) score is associated with headache frequency, pain intensity, headache symptoms, gender, and employment status. The MIDAS questionnaire is a 7-item questionnaire (with 5 scored items) designed to measure headache-related disability, to improve physician-patient communication, and to identify patients with high treatment needs. Data from 3 population-based studies (total sample, n = 397) conducted in the United States and the United Kingdom were used to evaluate the relationship between headache features (attack frequency, pain intensity, pain quality, and associated symptoms) and MIDAS score. Data on headache features were collected by telephone using a standardized interview. The MIDAS questionnaire was completed shortly after the telephone interview. General linear models were used to determine the extent to which population variation in the MIDAS score was explained by headache features. Using linear regression, variables for all headache features (ie, headache frequency, pain intensity, pain quality, and associated symptoms) and demographic characteristics explained only 22% of the variation in MIDAS scores. Almost all (19.9%) the explained variance was accounted for by average pain intensity (12.0%), number of headache days (6.1%), and exacerbation of pain with movement (1.8%). When pain intensity and headache frequency were included in the model, no statistically significant differences in MIDAS scores were observed by gender or employment status. Although explaining only 2.1% of the variance, age was significantly associated with MIDAS scores, with those under 25 years demonstrating higher MIDAS scores than other age groups. No other variables (ie, frequency of occurrence of associated symptoms and other measures of quality of pain) were associated with MIDAS scores. Challenges to the utility of the MIDAS as a measure include whether headache-related disability is largely

A central model for chronic tension-type headache (CTH) posits that stress contributes to headache, in part, by aggravating existing hyperalgesia in CTH sufferers. The prediction from this model that pain sensitivity mediates the relationship between stress and headache activity has not yet been examined. To determine whether pain sensitivity mediates the relationship between stress and prospective headache activity in CTH sufferers. Self-reported stress, pain sensitivity and prospective headache activity were measured in 53 CTH sufferers recruited from the general population. Pain sensitivity was modelled as a mediator between stress and headache activity, and tested using a nonparametric bootstrap analysis. Pain sensitivity significantly mediated the relationship between stress and headache intensity. The results of the present study support the central model for CTH, which posits that stress contributes to headache, in part, by aggravating existing hyperalgesia in CTH sufferers. Implications for the mechanisms and treatment of CTH are discussed.

Objective: To identify predictors of prognosis and trial outcomes in prospective studies of people with chronic headache. Methods: This was a systematic review of published literature in peer-reviewed journals. We included (1) randomized controlled trials (RCTs) of interventions for chronic headache that reported subgroup analyses and (2) prospective cohort studies, published in English, since 1980. Participants included adults with chronic headache (including chronic headache, chronic migraine, and chronic tension-type headache with or without medication overuse headache). We searched key databases using free text and MeSH terms. Two reviewers independently extracted data and assessed the methodologic quality of studies and overall quality of evidence identified using appropriate published checklists. Results: We identified 16,556 titles, removed 663 duplicates, and reviewed 199 articles, of which 27 were included in the review—17 prospective cohorts and 10 RCTs with subgroup analyses reported. There was moderate-quality evidence indicating that depression, anxiety, poor sleep and stress, medication overuse, and poor self-efficacy for managing headaches are potential prognostic factors for poor prognosis and unfavorable outcomes from preventive treatment in chronic headache. There was inconclusive evidence about treatment expectations, age, age at onset, body mass index, employment, and several headache features. Conclusions: This review identified several potential predictors of poor prognosis and worse outcome postinterventions in people with chronic headache. The majority of these are modifiable. The findings also highlight the need for more longitudinal high-quality research of prognostic factors in chronic headache. PMID:28615422

Extradural or subcutaneous cerebrospinal fluid (CSF) leakage is a common complication after spinal surgery and is associated with the risks of poor wound healing, meningitis, and pseudomeningocele. Numerous methods to prevent postoperative CSF leakage are available, but pressure-tight dural closure remains difficult, especially with synthetic surgical membranes. The efficacy of a novel dural closure technique was assessed by detecting extradural or subcutaneous CSF leakage on magnetic resonance imaging. The novel dural closure technique using absorbable polyglactin acid sheet and fibrin glue and the conventional procedure using only fibrin glue were evaluated retrospectively by identifying extradural or subcutaneous CSF leakage on magnetic resonance imaging scans in the acute (2-7 d) and chronic (3-6 mo) postoperative stages after spinal intradural surgery in 53 patients. The incidence of extradural and subcutaneous CSF leakage was significantly lower (P < 0.05) in the acute (20%) and chronic (0%) stages using polyglactin acid sheet and fibrin glue in 15 patients compared with that in the acute (81%) and chronic (24%) stages using only fibrin glue in 38 patients. One patient in the fibrin glue-only group required repair surgery for cutaneous CSF leakage. The combination of polyglactin acid sheet and fibrin glue can achieve water-tight closure after spinal intradural surgery and can minimize the risk of intractable postoperative CSF leakage. This simple, economical technique is recommended for dural closure after spinal intradural surgery.

To investigate the gradual failure of high-density polyethylene (HDPE) geomembrane as a result of long-term corrosion, four dynamic corrosion tests were conducted at different temperatures and durations. By combining tension and puncture tests, we systematically studied the variation law of tension and puncture properties of the HDPE geomembrane under different corrosion conditions. Results showed that tension and puncture failure of the HDPE geomembrane was progressive, and tensile strength in the longitudinal grain direction was evidently better than that in the transverse direction. Punctures appeared shortly after puncture force reached the puncture strength. The tensile strength of geomembrane was in inversely proportional to the corrosion time, and the impact of corrosion was more obvious in the longitudinal direction than transverse direction. As corrosion time increased, puncture strength decreased and corresponding deformation increased. As with corrosion time, the increase of corrosion temperature induced the decrease of geomembrane tensile strength. Tensile and puncture strength were extremely sensitive to temperature. Overall, residual strength had a negative correlation with corrosion time or temperature. Elongation variation increased initially and then decreased with the increase in temperature. However, it did not show significant law with corrosion time. The reduction in puncture strength and the increase in puncture deformation had positive correlations with corrosion time or temperature. The geomembrane softened under corrosion condition. The conclusion may be applicable to the proper designing of the HDPE geomembrane in landfill barrier system. PMID:28788321

As the transseptal (TS) puncture has become an integral part of many types of cardiac interventional procedures, its technique that was initial reported for measurement of left atrial pressure in 1950s, continue to evolve. Our laboratory adopted a modified technique which uses only coronary sinus catheter as the landmark to accomplishing TS punctures under fluoroscopy. The aim of this study is prospectively to evaluate the training and learning process for TS puncture guided by this modified technique. Guided by the training protocol, TS puncture was performed in 120 consecutive patients by three trainees without previous personal experience in TS catheterization and one experienced trainer as a controller. We analysed the following parameters: one puncture success rate, total procedure time, fluoroscopic time, and radiation dose. The learning curve was analysed using curve-fitting methodology. The first attempt at TS crossing was successful in 74 (82%), a second attempt was successful in 11 (12%), and 5 patients failed to puncture the interatrial septal finally. The average starting process time was 4.1 ± 0.8 min, and the estimated mean learning plateau was 1.2 ± 0.2 min. The estimated mean learning rate for process time was 25 ± 3 cases. Important aspects of learning curve can be estimated by fitting inverse curves for TS puncture. The study demonstrated that this technique was a simple, safe, economic, and effective approach for learning of TS puncture. Base on the statistical analysis, approximately 29 TS punctures will be needed for trainee to pass the steepest area of learning curve.

The objectives of this study were to determine the age and sex dependent linear trend of recurrent headache prevalence in schoolchildren in Mersin. A stratified sample composed of 5562 children; detailed characteristics were previously published. In this study the prevalence distribution of headache by age and sex showed a peak in the female population at the age of 11 (27.2%) with a plateau in the following years. The great stratified random sample results suggested that, in addition to socio-demographic features, detailed linear trend analysis showed headache features of children with headache have some specific characteristics dependent on age, gender and headache type.

Sinus stenosis occasionally occurs in dural arteriovenous fistulas. Sinus stenosis impedes venous outflow and aggravates intracranial hypertension by reversing cortical venous drainage. This study aimed to analyze the likelihood of sinus stenosis and its impact on cerebral hemodynamics of various types of dural arteriovenous fistulas. Forty-three cases of dural arteriovenous fistula in the transverse-sigmoid sinus were reviewed and divided into 3 groups: Cognard type I, type IIa, and types with cortical venous drainage. Sinus stenosis and the double peak sign (occurrence of 2 peaks in the time-density curve of the ipsilateral drainage of the internal jugular vein) in dural arteriovenous fistula were evaluated. "TTP" was defined as the time at which a selected angiographic point reached maximum concentration. TTP of the vein of Labbé, TTP of the ipsilateral normal transverse sinus, trans-fistula time, and trans-stenotic time were compared across the 3 groups. Thirty-six percent of type I, 100% of type IIa, and 84% of types with cortical venous drainage had sinus stenosis. All sinus stenosis cases demonstrated loss of the double peak sign that occurs in dural arteriovenous fistula. Trans-fistula time (2.09 seconds) and trans-stenotic time (0.67 seconds) in types with cortical venous drainage were the most prolonged, followed by those in type IIa and type I. TTP of the vein of Labbé was significantly shorter in types with cortical venous drainage. Six patients with types with cortical venous drainage underwent venoplasty and stent placement, and 4 were downgraded to type IIa. Sinus stenosis indicated dysfunction of venous drainage and is more often encountered in dural arteriovenous fistula with more aggressive types. Venoplasty ameliorates cortical venous drainage in dural arteriovenous fistulas and serves as a bridge treatment to stereotactic radiosurgery in most cases. © 2017 by American Journal of Neuroradiology.

At the turn of the century, most of the world's population lived in regions where the prevalence of headache was unknown and its impact poorly understood. Lifting The Burden (LTB), a nonprofit organization in official relations with the World Health Organization, established the Global Campaign against Headache, with the ultimate purpose of reducing the burden of headache worldwide. First, the scope and scale of this burden had to be known. LTB embarked upon a program of population-based studies in countries in all world regions in order to achieve its aim. Its studies have demonstrated a high prevalence of headache disorders, including migraine, tension-type headache, and medication-overuse headache, and their associations with impaired quality of life, substantial lost productivity, and high economic costs in every country surveyed. Informed by these, the Global Burden of Disease study ranks headache disorders as the second leading cause of years lived with disability worldwide; migraine alone is third among people aged 15 to 49 years. With interventions urgently needed to reduce these burdens throughout the world, we review the epidemiological studies conducted by LTB, examine proposed interventions to improve provision of headache care including a three-tier system of structured headache services, and consider the challenges still remaining in providing effective, efficient, and equitable headache care especially in low-income countries.

Chronic daily headache (CDH) represents a group of any headache disorder that occurs on a daily or near daily basis, for longer than 6 months. Even though it is a common problem, it is not a well defined disorder, resulting in controversies regarding its identification, description and approach. Three hundred patients, 232 women and 68 men, ages 16 to 86 (mean 38 years old for the women and 42 for the men), attending a headache center and fulfilling the proposed criteria for CDH (Silberstein et al.) and presenting headache 28 days per month were retrospectively studied. The clinical features allowed the primary headache diagnosis, before the transformation into daily presentation as: transformed migraine (TM ) in 271 patients (90,3%), chronic tension-type headache (CTTH) in 26 patients (8,7%) and new daily persistent headache (NDPH) in 3 patients (1%). Among the TM patients, the most observed presentation was pressure or tightening, bilateral fronto-temporal, moderate non-continuous headache, with a progressive onset. The association with nausea and phonophobia was demonstrated in 60% and 32% of the patients respectively. The association with photophobia and sleep disturbances, as well as the occurrence of intermittent headache attacks, was different among male and female patients. With regard to the CTTH patients, pressure or tightening, bilateral fronto-temporal, moderate non-continuous headache, with sleep disturbances and no associated symptoms, was the predominant presentation.

Headache associated with cough: a review

PubMed Central

2013-01-01

Headache only triggered by coughing is a rather uncommon condition. The aim of the present review is to present an overview of the diagnosis, clinical characteristics, pathophysiology and treatment of both primary and symptomatic cough headache and discuss other relevant headache disorders affected by coughing. The diagnosis of primary cough headache is made when headache is brought on and occurs only in association with coughing, straining or a Valsalva manoeuvre and in the absence of any abnormalities on neuro-imaging. In case an underlying pathology is identified as a cause of the headache, the diagnosis of symptomatic cough headache is made. The vast majority of these patients present with a Chiari malformation type I. Other frequently reported causes include miscellaneous posterior fossa pathology, carotid or vertebrobasilar disease and cerebral aneurysms. Consequently, diagnostic neuroimaging is key in the diagnosis of cough-related headache and guides treatment. Besides primary and symptomatic cough headache, several other both primary and secondary headache disorders exist where coughing acts as a trigger or aggravator of headache symptomatology.

In situ precise electrospinning of medical glue fibers as nonsuture dural repair with high sealing capability and flexibility.

PubMed

Lv, Fu-Yan; Dong, Rui-Hua; Li, Zhao-Jian; Qin, Chong-Chong; Yan, Xu; He, Xiao-Xiao; Zhou, Yu; Yan, Shi-Ying; Long, Yun-Ze

In this work, we propose an in situ precise electrospinning of medical glue fibers onto dural wound for improving sealing capability, avoiding tissue adhesion, and saving time in dural repair. N-octyl-2-cyanoacrylate, a commercial tissue adhesive (medical glue), can be electrospun into ultrathin fibrous film with precise and homogeneous deposition by a gas-assisted electrospinning device. The self-assembled N-octyl-2-cyanoacrylate film shows high compactness and flexibility owing to its fibrous structure. Simulation experiments on egg membranes and goat meninges demonstrated that this technology can repair small membrane defects quickly and efficiently. This method may have potential application in dural repair, for example, working as an effective supplementary technique for conventional dura suture.

Histology of the distal dural ring.

The distal dural ring (DDR) is a conserved intracranial anatomic structure marking the boundary point at which the internal carotid artery (ICA) exits the cavernous sinus (CS) and enters the subarachnoid space. Although the CS has been well described in a range of anatomic studies, to our knowledge no prior study has analyzed the histologic relationship between the ICA and DDR. Correspondingly, our objective was to assess the relationship of the DDR to the ICA and determine whether the DDR can be dissected from the ICA and thus divided, or can only be circumferentially trimmed around the artery. The authors examined ten fresh-frozen, adult cadaveric specimens. A standard frontotemporal craniotomy, orbito-optic osteotomy, and extradural anterior clinoidectomy was performed bilaterally. The cavernous ICA, DDR, and supraclinoid ICA were harvested as an en bloc specimen. Specimens formalin-fixed and paraffin-embedded prior to routine histochemical staining with hematoxylin and eosin and Masson trichrome. In all specimens, marked microscopic investment of the DDR throughout the ICA adventitia was noted. Dural collagen fibers extensively permeated the arterial layers superficial to the muscularis propria, with no evidence of a clear separation between the DDR and arterial adventitia. Histologic analysis suggests that the ICA and DDR are highly interrelated, continuous structures, and therefore attempted intraoperative dissection between these structures may carry an elevated risk of injury to the ICA. We correspondingly recommend careful circumferential trimming of the DDR in lieu of direct dissection in cases requiring mobilization of the clinoidal ICA. Clin.

1991-02-01

Cadaver grafts, laminated metallic materials, and synthetic fabrics have been evaluated as dural substitutes. Use of cadaver tissues is limited by fear of transmission of infectious disease while use of synthetic materials is associated with implant encapsulation and foreign body reactions. The purpose of this study is to evaluate the use of collagen film as a dural substitute. Collagen films prepared from bovine skin were used to replace the dura of rabbits and histological observations were made at 16, 28, 42, and 56 days postimplantation. Controls consisted of dura that was removed and then reattached. Control dura showed no signs of inflammation or adhesion to underlying tissue at 16 and 28 days postimplantation. By 56 days postimplantation, extensive connective tissue deposition was observed in close proximity to adjacent bone as well as pia arachnoid adhesions. Implanted collagen film behaved in a similar manner to control dura showing minimal inflammatory response at all time periods. At 56 days postimplantation collagen film appeared strongly infiltrated by connective tissue cells that deposited new collagen. The results of this study suggest that a reconstituted type I collagen film crosslinked with cyanamide acts as a temporary barrier preventing loss of fluid and adhesion formation. It is replaced after approximately 2 months with host collagen with limited inflammatory and fibrotic complications. Further studies are needed to completely characterize the new connective tissue formed as well as long-term biocompatibility and functioning of a reconstituted collagen dural substitute.

The prevalence of primary headache disorders in the general population provides a unique challenge in the evaluation of headache occurring in the context of sport. Despite a wealth of studies exploring the epidemiology of headache in the layperson, little is known about the prevalence and nature of headaches in collegiate student-athletes. These scenarios are challenging in the return to play context, as it is often unclear whether an athlete has an exacerbation of a primary headache disorder, new onset headache unrelated to trauma, or has suffered a concussive injury. To establish the prevalence and nature of headaches in collegiate student-athletes. Retrospective cross-sectional survey. This cross-sectional survey evaluated the characteristics and prevalence of headache in 834 student-athletes from four NCAA Division-I institutions. Because headache occurrence may vary by sport (collision, contact, non-contact), by sex, and medical history, our sample included male and female athletes in a variety of sports, with differing degrees of contact exposure. The 20 question survey collected data on personal and family history of headache, as well as concussion history. A total of 23.7% (n = 198) of participants reported having a personal history of migraine, 25.2% (n = 210) history of sinus headache, and 12.3% (n = 103) history of tension type headache. Among athletes with a prior history of concussion, 46.3% (n = 25) of females reported a history of migraine, while only 32.2% of males reported history of migraine (χ 2  = 3.421, P = .064). The etiology of increased prevalence of migraine in our study is unclear. Whether this is due to increased awareness of headache disorders, a consequence of contact exposure, or a predisposition for migraine development in this age group remains unclear.

This study was planned to investigate the prevalence of osmophobia in juvenile headache sufferers and to analyse the diagnostic utility of osmophobia in order to distinguish migraine without aura from episodic tension-type headache. We examined 305 consecutive patients presenting at our Paediatric Headache Centre. A semistructured questionnaire was given to 275 selected patients affected by migraine or tension-type headache. The prevalence of osmophobia during attacks was 18.5%, mainly in migraine patients (25.1%) vs. those with tension-type headache (8.3%). Osmophobia showed more specificity than phonophobia or photophobia in the differential diagnosis between migraine and tension-type headache. In conclusion, this study demonstrates that osmophobia resulted in a symptom with poor sensitivity (27.1%) but high specificity (92%) that could become a supportive diagnostic criterion even in children for the differential diagnosis between migraine without aura and tension-type headache.

Nummular headache: diagnosis and treatment.

PubMed

Pareja, Juan A; Pareja, Julia

2003-05-01

Nummular headache (coin-shaped cephalgia) has an unusual distinct feature: it is characterized by mild-to-moderate pressure-like pain exclusively felt in a rounded or elliptical area typically 2-6 cm in diameter. Although any region of the head may be affected, the parietal area is the common localization of nummular headache. The pain remains confined to the same symptomatic area which does not change in shape or size with time. The pain is continuous but lancinating exacerbations lasting for several seconds or gradually increasing from 10 mins to 2 h may superimpose the baseline pain. The temporal pattern is either chronic or remitting. Pseudoremissions may be observed when the pain reaches a very low grade or only discomfort (not pain) in the affected area is reported. At times, discomfort may prevail. Either during symptomatic periods or interictally, the affected area may show a variable combination of hypoethesia, dysesthesia, paresthesia or tenderness. Physical and supplementary examinations are normal. Nummular headache emerges as a primary clear-cut clinical picture. The particular topography and signs of sensory dysfunction make it reasonable to vent the idea that nummular headache is an extracranial headache, probably stemming from epicranial tissues such as terminal branches of sensitive nerves. Nummular headache may seem to be the paradigm of epicranias (group of headaches and pericranial neuralgias stemming from epicranial tissues). Nummular headache must be distinguished from head pain secondary to local processes and from tender points of more extensive headaches. Although nummular headache may frequently coexist with other primary headaches, it has an independent course. Treatment is seldom necessary and in most cases simple reassurance is sufficient.

Headaches can be triggered by a variety of factors. Military service members have a high prevalence of headache but the factors triggering headaches in military troops have not been identified. The objective of this study is to determine headache triggers in soldiers and military beneficiaries seeking specialty care for headaches. A total of 172 consecutive US Army soldiers and military dependents (civilians) evaluated at the headache clinics of 2 US Army Medical Centers completed a standardized questionnaire about their headache triggers. A total of 150 (87%) patients were active-duty military members and 22 (13%) patients were civilians. In total, 77% of subjects had migraine; 89% of patients reported at least one headache trigger with a mean of 8.3 triggers per patient. A wide variety of headache triggers was seen with the most common categories being environmental factors (74%), stress (67%), consumption-related factors (60%), and fatigue-related factors (57%). The types of headache triggers identified in active-duty service members were similar to those seen in civilians. Stress-related triggers were significantly more common in soldiers. There were no significant differences in trigger types between soldiers with and without a history of head trauma. Headaches in military service members are triggered mostly by the same factors as in civilians with stress being the most common trigger. Knowledge of headache triggers may be useful for developing strategies that reduce headache occurrence in the military.

Obesity and Headache: Part I – A Systematic Review of the Epidemiology of Obesity and Headache

Individually, both obesity and headache are conditions associated with a substantial personal and societal impact. Recent data support that obesity is comorbid with headache in general and migraine specifically, as well as with certain secondary headache conditions such as idiopathic intracranial hypertension. In the current manuscript, we first briefly review the epidemiology of obesity and common primary and secondary headache disorders individually. This is followed by a systematic review of the general population data evaluating the association between obesity and headache in general, and then obesity and migraine and tension-type headache disorders. Finally, we briefly discuss the data on the association between obesity and a common secondary headache disorder that is associated with obesity, idiopathic intracranial hypertension. Taken together, these data suggest that it is important for clinicians and patients to be aware of the headache/migraine-obesity association, given that it is potentially modifiable. Hypotheses for mechanisms of the obesity-migraine association and treatment considerations for overweight and obese headache sufferers are discussed in the companion manuscript, as part II of this topic.

Psychological factors in childhood headaches.

Recurrent headaches in children are most often migraines and are based in a genetic predisposition with a low headache threshold. As with any pain experience, there is a large emotional component associated with an attack of migraines that grows in amplitude as the headaches become more frequent and resistant to medicine, sleep, or other agents that used to work. Childhood headaches are especially complicated for 3 reasons: (1) the parents' fear (communicated to the child that serious medical pathology underlies the head pain), (2) the lack of evidence-based pharmacologic treatment, and (3) the belief that these headaches are largely psychological. This article addresses the mystery surrounding childhood headaches by delving into the influence of school, friends, and family; the impact of divorce; the coping skills required for a child to manage a migrainous nervous system; the potential secondary gain from headaches; psychiatric comorbidities and how to treat them; and the role of psychological intervention.

The protection of workers from chemical, biological, or radiological hazards requires the use of protective materials that can maintain their integrity during use. An accidental puncture in the protective material can result in a significant exposure to the worker. A five ply material has been developed that incorporates two layers of an electrically conductive polymer sandwiched between three layers of a nonconductive polymer. A normally open circuit that is connected between the conductive layers will be closed by puncturing the material with either a conductive or nonconductive object. This can be used to activate an audible alarm or visual beaconmore » to warn the worker of a breach in the integrity of the material. The worker is not connected to the circuit, and the puncture can be detected in real-time, even when caused by a nonconductor.« less

Chronic daily headache in the elderly.

2013-12-01

Disabling headache disorders are ubiquitous in all age groups, including the elderly, yet they are under-recognized, underdiagnosed and undertreated worldwide. Surveys and clinic-based research reports on headache disorders in elderly populations are extremely limited in number. Chronic daily headache (CDH) is an important and growing subtype of primary headache disorders, associated with increased burden and disruption to quality of life. CDH can be divided into two forms, based on headache duration. Common forms of primary headache disorders of long duration (>4 hours) were comprehensively defined in the third edition of the International Classification of Headache Disorders (ICHD-3 beta). These include chronic migraine, chronic tension-type headache, new daily persistent headache, and hemicrania continua. Rarer short-duration (<4 hours) forms of CDH are chronic cluster headache, chronic paroxysmal hemicrania, SUNCT, and hypnic headache. Accurate diagnosis, management, and relief of the burden of CDH in the elderly population present numerous unique challenges as the "aging world" continues to grow. In order to implement appropriate coping strategies for the elderly, it is essential to establish the correct diagnosis at each step and to exercise caution in differentiating from secondary causes, while always taking into consideration the unique needs and limitations of the aged body.

Patients with sudden onset headache not meeting the criteria of the International Headache Society for new daily persistent headache. How to classify them?

We conducted a retrospective analysis of the records of 1348 patients regularly treated at the headache clinic of Department of Neurology of Santa Casa de São Paulo, Brazil. Sixty-two patients reported history of daily and persistent headache. From the 62 patients selected, only 21 (group 1) could be diagnosed with new daily-persistent headache (NDPH) according to the International Headache Society (HIS) 2004 criteria. The 41 remaining patients (group 2) could not be diagnosed with NDPH according to IHS-2004 once they presented two or more migraine attack-related symptoms, such as: nausea, photophobia, phonophobia and vomiting, in different combinations. It was not possible to classify them in groups 1 to 4 of primary headaches either. How to classify them? We suggest that the criteria are revised. And one way we can classify them, would be the subdivision: NDPH with migraine features and without migraine features that would allow the inclusion of all individuals present who has a daily and persistent headache from the beginning.

Puncture Self-Healing Polymers for Aerospace Applications

Space exploration launch costs on the order of $10K per pound provide ample incentive to seek innovative, cost-effective ways to reduce structural mass without sacrificing safety and reliability. Damage-tolerant structural systems can provide a route to avoiding weight penalty while enhancing vehicle safety and reliability. Self-healing polymers capable of spontaneous puncture repair show great promise to mitigate potentially catastrophic damage from events such as micrometeoroid penetration. Effective self-repair requires these materials to heal instantaneously following projectile penetration while retaining structural integrity. Poly(ethylene-co-methacrylic acid) (EMMA), also known as Surlyn is an ionomer-based copolymer that undergoes puncture reversal (self-healing) following high impact puncture at high velocities. However EMMA is not a structural engineering polymer, and will not meet the demands of aerospace applications requiring self-healing engineering materials. Current efforts to identify candidate self-healing polymer materials for structural engineering systems are reported. Rheology, high speed thermography, and high speed video for self-healing semi-crystalline and amorphous polymers will be reported.

Oblique Intrathecal Injection in Lumbar Spine Surgery: A Technical Note.

PubMed

2017-09-01

Intrathecal morphine (ITM) is an efficacious method of providing postoperative analgesia and reducing pain associated complications. Despite adoption in many surgical fields, ITM has yet to become a standard of care in lumbar spine surgery. Spine surgeons' reticence to make use of the technique may in part be attributed to concerns of precipitating a cerebrospinal fluid (CSF) leak. Herein we describe a method for oblique intrathecal injection during lumbar spine surgery to minimize risk of CSF leak. The dural sac is penetrated obliquely at a 30° angle to offset dural and arachnoid puncture sites. Oblique injection in instances of limited dural exposure is made possible by introducing a 60° bend to a standard 30-gauge needle. The technique was applied for injection of ITM or placebo in 104 cases of lumbar surgery in the setting of a randomized controlled trial. Injection was not performed in two cases (2/104, 1.9%) following preinjection dural tear. In the remaining 102 cases no instances of postoperative CSF leakage attributable to oblique intrathecal injection occurred. Three cases (3/102, 2.9%) of transient CSF leakage were observed immediately following intrathecal injection with no associated sequelae or requirement for postsurgical intervention. In two cases, the observed leak was repaired by sealing with fibrin glue, whereas in a single case the leak was self-limited requiring no intervention. Oblique dural puncture was not associated with increased incidence of postoperative CSF leakage. This safe and reliable method of delivery of ITM should therefore be routinely considered in lumbar spine surgery.

Introduction Carbon monoxide (CO) is an endogenously produced signalling molecule that has a role in nociceptive processing and cerebral vasodilatation. We hypothesized that inhalation of CO would induce headache and vasodilation of cephalic and extracephalic arteries. Methods In a randomized, double-blind, placebo-controlled crossover design, 12 healthy volunteers were allocated to inhalation of CO (carboxyhemoglobin 22%) or placebo on two separate days. Headache was scored on a verbal rating scale from 0-10. We recorded mean blood velocity in the middle cerebral artery (VMCA) by transcranial Doppler, diameter of the superficial temporal artery (STA) and radial artery (RA) by high-resolution ultrasonography and facial skin blood flow by laser speckle contrast imaging. Results Ten volunteers developed headache after CO compared to six after placebo. The area under the curve for headache (0-12 hours) was increased after CO compared with placebo ( p = 0.021). CO increased VMCA ( p = 0.002) and facial skin blood flow ( p = 0.012), but did not change the diameter of the STA ( p = 0.060) and RA ( p = 0.433). Conclusion In conclusion, the study demonstrated that CO caused mild prolonged headache but no arterial dilatation in healthy volunteers. We suggest this may be caused by a combination of hypoxic and direct cellular effects of CO.

To investigate the diagnostic accuracy of needle puncture biopsy and pathological examination of frozen during operation for pulmonary nodules, and whether this diagnostic method can replace tumor resection examination. Totally 50 patients (28 males and 22 females, average age was 59 years) who had the single nodule after imaging examination without any pathological diagnostic from January to October 2010 were selected in this research work. During open operation or video assisted thoracic surgery, needle (14 G model) was used to puncture biopsy for pathological examination of frozen. All the adverse events during puncture biopsy would be recorded. The resection specimens would be accepted paraffin pathological examination. The relationship between puncture frozen pathological and paraffin pathological examination was analyzed. All tumor sizes were ranged from 1.0 cm × 0.6 cm to 5.6 cm × 9.0 cm. The paraffin pathological examination after operation as the golden standard, there were 7 cases of benign tumor and 43 cases of malignant tumor. The diagnostic sensitivity of puncture biopsy was 90.7%, the specificity was 100%, the positive predictive value was 100% and the negative predictive value was 63.6%. There were 11 cases of benign tumor diagnosed by needle puncture biopsy, among which 4 cases were proved as malignant tumor by paraffin pathology, and the false negative rate was 9.3%. The main risk of puncture biopsy was bleeding after puncture immediately, and the rate was 4.0% (2/50). The puncture biopsy during operation had a high specificity for malignant lung tumor, and there was a certain false negative rate for benign tumor. Puncture biopsy and pathological examination of frozen tissue can replace tumor section biopsy in a way.

Headache classification: criticism and suggestions.

Manzoni, G C; Torelli, P

2004-10-01

The International Classification of Headache Disorders 2nd Edition (ICHD-II), published in 2004, marks an unquestionable progress from the preceding 1988 edition, but the in-depth analysis it offers is not immune from drawbacks and shortcomings. First of all, it is still basically a classification of attacks and not of syndromes. For the migraine group, while the revised classification more accurately characterises migraine with aura, it fails to provide a sufficiently structured description of those forms of migraine without aura that over the years evolve to so-called daily chronic forms. These forms are not adequately recognised as chronic migraine, which ICHD-II includes among the complications of migraine. The inclusion of short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) in the cluster headache group is bound to generate some perplexity, while the recognition of new daily persistent headache (NDPH) included in the group of other primary headaches as a separate clinical entity appears somewhat premature. Doubts are also raised by the actual existence of triptan-overuse headache, which ICHD-II includes in Group 8 among medication-overuse headaches. Finally, the addition of headache attributed to psychiatric disorder, which is certainly a good option in perspective, is not yet supported by an adequate systematisation.

Headaches related to sexual activity.

PubMed Central

Lance, J W

1976-01-01

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.

Sleep apnoea and chronic headache.

The objective of this study was to estimate prevalence of headache and body pain among patients referred for suspected sleep apnoea syndrome compared with the occurrence in a large population-based study (the Nord-Trøndelag Health Study). Between 1995 and 1998, ambulatory polysomnography was successfully performed in 421 consecutive patients, 324 of whom completed a questionnaire about sleep-related habits, headache and body pain. Headache and neck pain were more likely among patients admitted for polysomnography compared with the general population (n = 41 340). In the multivariate analyses, this association was mainly restricted to those with frequent complaints (> or =7 days per month). Chronic headache (headache > or = 15 days per month) was seven times more common among individuals with and without confirmed obstructive sleep apnoea syndrome than in the general population. There was no linear dose-response relationship between headache and neck pain and severity of apnoea or oxygen desaturation. Thus, hypoxia per se is less likely to explain the high headache prevalence among patients admitted for polysomnography.

To assess iris neovascularization by uveal puncture of the mouse eye and determine the role of angiogenic factors during iris neovascularization. Uveal punctures were performed on BalbC mouse eyes to induce iris angiogenesis. VEGF-blockage was used as an anti-angiogenic treatment, while normoxia- and hypoxia-conditioned media from retinal pigment epithelium (RPE) cells was used as an angiogenic-inducer in this model. Iris vasculature was determined in vivo by noninvasive methods. Iris blood vessels were stained for platelet endothelial cell adhesion molecule-1 and vascular sprouts were counted as markers of angiogenesis. Expression of angiogenic and inflammatory factors in the puncture-induced model were determined by qPCR and western blot. Punctures led to increased neovascularization and sprouting of the iris. qPCR and protein analysis showed an increase of angiogenic factors, particularly in the plasminogen-activating receptor and inflammatory systems. VEGF-blockage partly reduced iris neovascularization, and treatment with hypoxia-conditioned RPE medium led to a statistically significant increase in iris neovascularization. This study presents the first evidence of a puncture-induced iris angiogenesis model in the mouse. In a broader context, this novel in vivo model of neovascularization has the potential for noninvasive evaluation of angiogenesis modulating substances.

This paper presents the long-term results of an animal trial of a collagen biomatrix (TISSUDURA, Baxter AG, Vienna/Austria) for the repair and regeneration of dural defects. This product provides a matrix with a special layer structure and consists of pure naturally cross-linked collagen of equine origin. The comparable material is Tutoplast Dura, a human cadaveric-derived dural graft preserved in a multiple stage chemical process. Bihemispheric parietotoccipital dural defects of a defined size were induced in 25 sheep and subsequently closed with the collagen graft or Tutoplast Dura, respectively. Postoperative neurological abnormalities did not occur in any animal. There were no signs of graft rejection or formation of cerebrospinal fluid fistulae. The collagen graft site displayed histological signs as early as 2 weeks postoperatively consistent with a moderate Iymphocytic inflammatory response and infiltration with fibroblasts and macrophages. The graft subsequently developed a neodura-like connective tissue architecture. The Tutoplast Dura showed only minimal cellular infiltration, and again the surrounding structures displayed a mild inflammatory response. 24 weeks postoperatively, the dura and neomembrane were barely distinguishable at the collagen biomatrix site, but the Tutoplast Dura displayed inadequate fusion with the dural border and was encapsulated in a connective tissue layer. The outcomes demonstrate that the collagen graft can be used for dura reconstruction as a temporary dural replacement and at the same time as a biomatrix for dural regeneration.

Technological advances and changing indications for lumbar puncture in neurological disorders.

Technological advances have changed the indications for and the way in which lumbar puncture is done. Suspected CNS infection remains the most common indication for lumbar puncture, but new molecular techniques have broadened CSF analysis indications, such as the determination of neuronal autoantibodies in autoimmune encephalitis. New screening techniques have increased sensitvity for pathogen detection and can be used to identify pathogens that were previously unknown to cause CNS infections. Evidence suggests that potential treatments for neurodegenerative diseases, such as Alzheimer's disease, will rely on early detection of the disease with the use of CSF biomarkers. In addition to being used as a diagnostic tool, lumbar puncture can also be used to administer intrathecal treatments as shown by studies of antisense oligonucleotides in patients with spinal muscular atrophy. Lumbar puncture is generally a safe procedure but complications can occur, ranging from minor (eg, back pain) to potentially devastating (eg, cerebral herniation). Evidence that an atraumatic needle tip design reduces complications of lumbar puncture is compelling, and reinforces the need to change clinical practice. Copyright © 2018 Elsevier Ltd.

Oppegard, Shawn C; Anderson, Peter A; Eddington, David T

2009-01-01

Background Cnidocysts isolated from cnidarian organisms are attractive as a drug-delivery platform due to their fast, efficient delivery of toxins. The cnidocyst could be utilized as the means to deliver therapeutics in a wearable drug-delivery patch. Cnidocysts have been previously shown to discharge upon stimulation via electrical, mechanical, and chemical pathways. Cnidocysts isolated from the Portuguese Man O' War jellyfish (Physalia physalis) are attractive for this purpose because they possess relatively long threads, are capable of puncturing through hard fish scales, and are stable for years. Results As a first step in using cnidocysts as a functional component of a drug delivery system, the puncture mechanics of the thread were characterized. Tentacle-contained cnidocysts were used as a best-case scenario due to physical immobilization of the cnidocysts within the tentacle. Ex vivo tentacle-contained cnidocysts from Physalia possessed an elastic modulus puncture threshold of approximately 1-2 MPa, based on puncture tests of materials with a gamut of hardness. Also, a method for inducing discharge of isolated cnidocysts was found, utilizing water as the stimulant. Preliminary lectin-binding experiments were performed using fluorophore-conjugated lectins as a possible means to immobilize the isolated cnidocyst capsule, and prevent reorientation upon triggering. Lectins bound homogeneously to the surface of the capsule, suggesting the lectins could be used for cnidocyst immobilization but not orientation. Conclusion Cnidocysts were found to puncture materials up to 1 MPa in hardness, can be discharged in a dry state using water as a stimulant, and bind homogeneously to lectins, a potential means of immobilization. The information gained from this preliminary work will aid in determining the materials and design of the patch that could be used for drug delivery. PMID:19785761

The configurations of cerebral veins and dural venous sinuses differ not only between individuals, but also between the two brain hemispheres of an individual, making the anatomical classification of the cerebral veins difficult. We evaluated the superior dural venous sinuses and classified their types and variations using magnetic resonance venography (MRV) and digital substraction angiography (DSA). A total of 394 patients were studied retrospectively. Superior dural venous sinuses were evaluated and the confluence of the sinuses was classified on 2-dimensional time-of-flight MRV, contrast-enhanced 3-dimensional spoiled gradient recalled echo magnetic resonance imaging, and/or cerebral DSA. Confluens sinuum was divided into three types: true confluence, partial confluence, and non-confluence. Of the three types, partial confluence (type II) was most frequently seen. Co-dominance of the transverse sinuses was most frequently observed. An occipital sinus was observed in 15 % of the patients. There were statistically significant differences between the left transverse sinus agenesis and the presence of the occipital sinus (p < 0.001), between the co-presence of the partial confluence type torcular and the occipital sinus (p = 0.040), and between the co-presence of the fenestrated straight sinus and the occipital sinus (p = 0.010). Although anatomical variations of dural venous sinuses are seen frequently, classification of venous sinuses helps surgeons in preoperative evaluation and management, and prevention of possible complications. In this study, we think that a comprehensive evaluation and classification of dural venous sinuses is a significant contribution to the literature.

Side-locked headaches: an algorithm-based approach.

PubMed

Prakash, Sanjay; Rathore, Chaturbhuj

2016-12-01

The differential diagnosis of strictly unilateral hemicranial pain includes a large number of primary and secondary headaches and cranial neuropathies. It may arise from both intracranial and extracranial structures such as cranium, neck, vessels, eyes, ears, nose, sinuses, teeth, mouth, and the other facial or cervical structure. Available data suggest that about two-third patients with side-locked headache visiting neurology or headache clinics have primary headaches. Other one-third will have either secondary headaches or neuralgias. Many of these hemicranial pain syndromes have overlapping presentations. Primary headache disorders may spread to involve the face and / or neck. Even various intracranial and extracranial pathologies may have similar overlapping presentations. Patients may present to a variety of clinicians, including headache experts, dentists, otolaryngologists, ophthalmologist, psychiatrists, and physiotherapists. Unfortunately, there is not uniform approach for such patients and diagnostic ambiguity is frequently encountered in clinical practice.Herein, we review the differential diagnoses of side-locked headaches and provide an algorithm based approach for patients presenting with side-locked headaches. Side-locked headache is itself a red flag. So, the first priority should be to rule out secondary headaches. A comprehensive history and thorough examinations will help one to formulate an algorithm to rule out or confirm secondary side-locked headaches. The diagnoses of most secondary side-locked headaches are largely investigations dependent. Therefore, each suspected secondary headache should be subjected for appropriate investigations or referral. The diagnostic approach of primary side-locked headache starts once one rule out all the possible secondary headaches. We have discussed an algorithmic approach for both secondary and primary side-locked headaches.

Ocular syphilis has become rare in the developed world, but is a common presentation to ophthalmology departments in South Africa. We investigated the proportion of patients diagnosed with ocular syphilis who went on to receive lumbar punctures, and determined the fraction of these who had cerebrospinal fluid findings suggestive of neurosyphilis. We aimed to determine whether the use of lumbar punctures in ocular syphilis patients was beneficial in picking up cases of neurosyphilis. Retrospective study of case notes of patients admitted to two district hospitals in Durban, South Africa, with ocular syphilis over a 20-month period. A total of 31 of 68 ocular syphilis patients underwent lumbar puncture, and of these, eight (25.8%) had findings suggestive of neurosyphilis. Lumbar puncture in ocular syphilis patients should continue to be a routine part of the investigation of these patients; a large proportion of ocular syphilis patients show cerebrospinal fluid findings suggestive of neurosyphilis, are at risk of the complications of neurosyphilis, and should be managed accordingly.

Headache is considered as a common symptom of heat stress disorders (HSD), but no forms of secondary headache from heat exposure are reported in the International Classification of Headache Disorders-2 Edition (ICHD-II). Heat-stroke (HS) is the HSD most severe condition, it may be divided into two forms: classic (due to a long period environmental heat exposure) and exertional (a severe condition caused by strenuous physical exercises in heat environmental conditions). Here we report the case of a patient who developed a headache clinical picture fulfilling the diagnostic criteria for new daily persistent headache (NDPH), after an exertional HS, and discuss about possible pathophysiological mechanisms and classification aspects of headache induced by heat conditions.

The aim of this study was to investigate the characteristics of headache in patients with Behçet's disease (BD) seeking neurological consultation. Consecutive patients with BD seen within 1 year at the neuro-Behçet's out-patient clinic were studied using an electronic database according to the classification criteria of the International Headache Society. During a 12-month period 118 BD patients were admitted, and 98 had headaches. Migraine was the most common type of primary headache diagnosed in 45 patients (46.4%) in the whole headache group, followed by tension-type headache (TTH) in 26 cases (26.8%). Thirty-seven patients had secondary headaches mainly due to cerebral venous thrombosis or parenchymal neurological involvement of BD. Of these patients, 15 had both primary and secondary headaches. The primary headaches of 13 patients were exacerbated with systemic BD flare-ups, and four patients had migraine attacks triggered only by systemic BD activation which showed a good response to the treatment of systemic inflammation. The majority of the headaches of patients with BD do not indicate any neurological involvement; they are usually due to migraine or TTH. In a minority of patients, migraine associated with systemic inflammation of BD is notable.

Evaluate the safety and efficacy of in-office secondary tracheoesophageal puncture (TEP) technique using transnasal esophagoscopy (TNE) and the Seldinger technique in conjunction with a cricothyroidotomy kit for placement. Case series with chart review. Academic medical center. A retrospective chart review was performed on 83 subjects who underwent in-office secondary TEP. Variables that were examined included disease site, staging, histologic diagnosis, extent of resection and reconstruction, chemoradiation, functional voice status (as assessed by speech pathologist in most recent note), and complications directly related to the procedure. Eighty-three individuals from our institution met our criteria for in-office secondary TEP from 2005 to August 2012. Of these, 97.6% (81/83) had no complications of TEP. The overall complication rate was 2.4% (2/83). Complications included bleeding from puncture site and closure of puncture site after dislodgement of prosthesis at the time of puncture. Fluent conversational speech was achieved in 69.9% of all patients (58/83), and an additional 19.3% (16/83) achieved functional/intelligible speech; of those, 3.6% (3/83) were unable to achieve fluent conversational speech due to anatomic defects from previous surgery. An in-office TEP can be safely performed using the Seldinger technique with direct visualization using TNE, despite the extent of resection or reconstruction, with functional speech outcomes comparable to other studies available in the literature.

Objective: To characterize demographic and clinical features in pregnant women presenting with acute headache, and to identify clinical features associated with secondary headache. Methods: We conducted a 5-year, single-center, retrospective study of consecutive pregnant women presenting to acute care with headache receiving neurologic consultation. Results: The 140 women had a mean age of 29 ± 6.4 years and often presented in the third trimester (56.4%). Diagnoses were divided into primary (65.0%) and secondary (35.0%) disorders. The most common primary headache disorder was migraine (91.2%) and secondary headache disorders were hypertensive disorders (51.0%). The groups were similar in demographics, gestational ages, and most headache features. In univariate analysis, secondary headaches were associated with a lack of headache history (36.7% vs 13.2%, p = 0.0012), seizures (12.2% vs 0.0%, p = 0.0015), elevated blood pressure (55.1% vs 8.8%, p < 0.0001), fever (8.2% vs 0.0%, p = 0.014), and an abnormal neurologic examination (34.7% vs 16.5%, p = 0.014). In multivariate logistic regression, elevated blood pressure (odds ratio [OR] 17.0, 95% confidence interval [CI] 4.2–56.0) and a lack of headache history (OR 4.9, 95% CI 1.7–14.5) had an increased association with secondary headache, while psychiatric comorbidity (OR 0.13, 95% CI 0.021–0.78) and phonophobia (OR 0.29, 95% CI 0.09–0.91) had a reduced association with secondary headache. Conclusions: Among pregnant women receiving inpatient neurologic consultation, more than one-third have secondary headache. Diagnostic vigilance should be heightened in the absence of a headache history and if seizures, hypertension, or fever are present. Attack features may not adequately distinguish primary vs secondary disorders, and low thresholds for neuroimaging and monitoring for preeclampsia are justified. PMID:26291282

Orgasmic headache (OH) is a sudden and severe headache that occurs at the time of or shortly after an orgasm. AIM.: We present the case of typical primary headache associated with sexual activity, especially during an orgasmic period. A 34-year-old man complained of sudden and severe headache during sexual activity, or orgasmic period, for 2 months. The headache developed abruptly with an orgasm and then decreased shortly over a period of 4 ≈ 8 hours. Magnetic resonance angiography revealed severe spasm of the M1 segment of both the middle cerebral arteries. He was treated with oral nimodipine (30 mg every 8 hours), which alleviated the headache and prevented its recurrence. We postulated a pathophysiological relationship between OH and migraine, especially with respect to vasoconstriction, and believe that in such cases, nimodipine may be an effective therapy. © 2013 International Society for Sexual Medicine.

The objective of the study was to determine whether adolescents with headache have more disc degeneration in the cervical spine than headache-free controls. This study is part of a population-based follow-up study of adolescents with and without headache. At the age of 17 years, adolescents with headache at least three times a month (N = 47) and adolescents with no headache (N = 22) participated in a magnetic resonance imaging (MRI) study of the cervical spine. Of the 47 headache sufferers, 17 also had weekly neck pain and 30 had neck pain less than once a month. MRI scans were interpreted independently by three neuroradiologists. Disc degeneration was found in 67% of participants, with no difference between adolescents with and without headache. Most of the degenerative changes were located in the lower cervical spine. In adolescence, mild degenerative changes of the cervical spine are surprisingly common but do not contribute to headache.

Recent developments in pediatric headache.

This review will focus on some of the recent findings in pediatric headache including headache characteristics, epidemiology, comorbid associations and treatment updates. Pediatric headache remains a frequent health problem for children and their families, yet there remain many gaps in our knowledge. This review will broadly address some of the recent findings and highlight the gaps in our understanding and treatment of pediatric headache. There will be a focus on pediatric migraine as this has been the best characterized and studied. Our understanding of pediatric headache is improving with increased recognition of the characteristics and associated symptomology. This should further guide the individualized treatment approaches for improved outcome and reduction of progression into adulthood.

Reliability and performance of innovative surgical double-glove hole puncture indication systems.

During operative procedures, operating room personnel wear sterile surgical gloves designed to protect them and their patients against transmissible infections. The Food and Drug Administration (FDA) has set compliance policy guides for manufacturers of gloves. The FDA allows surgeons' gloves whose leakage defect rates do not exceed 1.5 acceptable quality level (AQL) to be used in operating rooms. The implications of this policy are potentially enormous to operating room personnel and patients. This unacceptable risk to the personnel and patient could be significantly reduced by the use of sterile double surgical gloves. Because double-gloves are also susceptible to needle puncture, a double-glove hole indication system is urgently needed to immediately detect surgical needle glove punctures. This warning would allow surgeons to remove the double-gloves, wash their hands, and then don a sterile set of double-gloves with an indication system. During the last decade, Regent Medical has devised non-latex and latex double-glove hole puncture indication systems. The purpose of this comprehensive study is to detect the accuracy of the non-latex and latex double-glove hole puncture indication systems using five commonly used sterile surgical needles: the taper point surgical needle, tapercut surgical needle, reverse cutting edge surgical needle, taper cardiopoint surgical needle, and spatula surgical needle. After subjecting both the non-latex and latex double-glove hole puncture indication systems to surgical needle puncture in each glove fingertip, these double-glove systems were immersed in a sterile basin of saline, after which the double-gloved hands manipulated surgical instruments. Within two minutes, both the non-latex and latex hole puncture indication systems accurately detected needle punctures in all of the surgical gloves, regardless of the dimensions of the surgical needles. In addition, the size of the color change visualized through the translucent outer

In recent years, there has been an increase in the reports indicating a form of headache that occurs during commercial aircraft travel. This headache, called airplane headache by some authors, is believed to be a new type of headache. The headache has very specific characteristics and all of the cases exhibited very stereotypical symptoms. The headache starts suddenly during the ascent and/or descent of the commercial aircraft. It has a mean duration of 20 minutes, which is usually unilateral and commonly localized to periorbital region. The headache is described to be severe, and has a stabbing or jabbing nature, and generally subsides in a short time. In some cases, an organic cause can be identified whereas in others no organic pathology could be found. We described the clinical features of 22 cases who suffered from a headache that occurred during airplane travel. We examined other cases with similar features reported in the literature and proposed preliminary diagnostic criteria for this new form of headache. We also discussed the possible patholophysiological mechanisms that may cause this headache.

Cranial vault remodeling surgery for craniosynostosis carries the potential risk of dural venous sinus injury given the extensive bony exposure. Identification of the dural venous sinuses can be challenging in patients with craniosynostosis given the lack of accurate surface-localizing landmarks. Computer-aided design and manufacturing (CAD/CAM) has allowed surgeons to pre-operatively plan these complex procedures in an effort to increase reconstructive efficiency. An added benefit of this technology is the ability to intraoperatively map the dural venous sinuses based on pre-operative imaging. We utilized CAD/CAM technology to intraoperatively map the dural venous sinuses for patients undergoing reconstructive surgery for craniosynostosis in an effort to prevent sinus injury, increase operative efficiency, and enhance patient safety. Here, we describe our experience utilizing this intraoperative technology in pediatric patients with craniosynostosis. We retrospectively reviewed the charts of children undergoing reconstructive surgery for craniosynostosis using CAD/CAM surgical planning guides at our institution between 2012 and 2016. Data collected included the following: age, gender, type of craniosynostosis, estimated blood loss, sagittal sinus deviation from the sagittal suture, peri-operative outcomes, and hospital length of stay. Thirty-two patients underwent reconstructive cranial surgery for craniosynostosis, with a median age of 11 months (range, 7-160). Types of synostosis included metopic (6), unicoronal (6), sagittal (15), lambdoid (1), and multiple suture (4). Sagittal sinus deviation from the sagittal suture was maximal in unicoronal synostosis patients (10.2 ± 0.9 mm). All patients tolerated surgery well, and there were no occurrences of sagittal sinus, transverse sinus, or torcular injury. The use of CAD/CAM technology allows for accurate intraoperative dural venous sinus localization during reconstructive surgery for craniosynostosis and

Headache and neuropsychic disorders in the puerperium: a case report with suspected deficiency of urea cycle enzymes.

Tonini, Maria Clara; Bignamini, V; Mattioli, M

2011-05-01

An enzymatic abnormality of the urea cycle is a metabolic disorder occasionally seen in adults, but particularly in the puerperium. The main risk is acute hyperammoniemic encephalopathy, leading to psychosis, coma and even death if not diagnosed promptly and treated appropriately. Headache is frequent in the puerperium normally manifesting between 3 and 6 days after delivery. We describe here a 39-year-old woman, who 3 days after delivery presented diffuse tension-type headache and depression, followed by behavioral disorders, psychomotor agitation, epileptic seizures, and finally coma 2 days later. Pregnancy and normal delivery: routine blood chemistry findings, CT scan, MR imaging, angio-MR of the brain, and lumbar puncture were normal. EEG when seizures started, it showed diffuse slowing, as in the case of metabolic encephalopathy. This led us to assay blood ammonia, which was high at >400 mmol. Liver function and abdominal US were normal; hence, we suspected a urea cycle enzymatic abnormality, and requested for genetic tests. These confirmed a congenital primary metabolic deficiency of arginine succinate synthetase, with high citrullinemia (type II, adult form). Dialysis was started promptly, with initially iv arginine, then orally, plus medical therapy for the hyperammoniemia and a low protein diet; plasma ammonia dropped swiftly to normal, and her state of consciousness gradually improved until all the clinical symptoms had resolved. Ammonia assay should always be considered in the first few days of the puerperium in women with headache and behavioral disorders, to exclude an inborn deficiency of the urea cycle, which may have gone unnoticed until then.

Soft elastomeric membrane structures are widely used and commonly found in engineering and biological applications. Puncture is one of the primary failure modes of soft elastomeric membrane at large deformation when indented by rigid objects. In order to investigate the puncture failure mechanism of soft elastomeric membrane with large deformation, we study the deformation and puncture failure of silicone rubber membrane that results from the continuous axisymmetric indentation by cylindrical steel indenters experimentally and analytically. In the experiment, effects of indenter size and the friction between the indenter and the membrane on the deformation and puncture failure of the membrane are investigated. In the analytical study, a model within the framework of nonlinear field theory is developed to describe the large local deformation around the punctured area, as well as to predict the puncture failure of the membrane. The deformed membrane is divided into three parts and the friction contact between the membrane and indenter is modeled by Coulomb friction law. The first invariant of the right Cauchy-Green deformation tensor I1 is adopted to predict the puncture failure of the membrane. The experimental and analytical results agree well. This work provides a guideline in designing reliable soft devices featured with membrane structures, which are present in a wide variety of applications.

A new posterior iliac puncture/aspiration needle.

PubMed

Islam, Anwarul

2016-03-25

The needles that are currently used for obtaining bone marrow aspirate samples from the posterior ilium are typically those of 1930s vintage (eg, Klima, Salah or similar needles), which were specifically designed for sternal aspiration. These needles are not designed to obtain bone marrow aspirate samples from the posterior ilium and as a result they are unsatisfactory particularly if the patient is large or obese. A new posterior iliac puncture/aspiration needle has therefore been designed, which is particularly suited for bone marrow aspiration from the posterior ilium. The needle was tested on five cadavers and on five patients. The design and construction of the needle was found to be satisfactory and a marked improvement over the conventional sternal puncture needles particularly when large or obese patients were concerned. The new posterior iliac bone marrow aspiration needle has advantages that overcome the limitations of using a conventional sternal puncture needle to obtain marrow aspirates from the posterior ilium.

Simple Systems for Detecting Spacecraft Meteoroid Punctures

NASA Technical Reports Server (NTRS)

Hall, Stephen B.

2004-01-01

A report describes proposed systems to be installed in spacecraft to detect punctures by impinging meteoroids or debris. Relative to other systems that have been used for this purpose, the proposed systems would be simpler and more adaptable, and would demand less of astronauts attention and of spacecraft power and computing resources. The proposed systems would include a thin, hollow, hermetically sealed panel containing an inert fluid at a pressure above the spacecraft cabin pressure. A transducer would monitor the pressure in the panel. It is assumed that an impinging object that punctures the cabin at the location of the panel would also puncture the panel. Because the volume of the panel would be much smaller than that of the cabin, the panel would lose its elevated pressure much faster than the cabin would lose its lower pressure. The transducer would convert the rapid pressure drop to an electrical signal that could trigger an alarm. Hence, the system would provide an immediate indication of the approximate location of a small impact leak, possibly in time to take corrective action before a large loss of cabin pressure could occur.

Headaches associated with refractive errors: myth or reality?

PubMed

Gil-Gouveia, R; Martins, I P

2002-04-01

Headache and refractive errors are very common conditions in the general population, and those with headache often attribute their pain to a visual problem. The International Headache Society (IHS) criteria for the classification of headache includes an entity of headache associated with refractive errors (HARE), but indicates that its importance is widely overestimated. To compare overall headache frequency and HARE frequency in healthy subjects with uncorrected or miscorrected refractive errors and a control group. We interviewed 105 individuals with uncorrected refractive errors and a control group of 71 subjects (with properly corrected or without refractive errors) regarding their headache history. We compared the occurrence of headache and its diagnosis in both groups and assessed its relation to their habits of visual effort and type of refractive errors. Headache frequency was similar in both subjects and controls. Headache associated with refractive errors was the only headache type significantly more common in subjects with refractive errors than in controls (6.7% versus 0%). It was associated with hyperopia and was unrelated to visual effort or to the severity of visual error. With adequate correction, 72.5% of the subjects with headache and refractive error reported improvement in their headaches, and 38% had complete remission of headache. Regardless of the type of headache present, headache frequency was significantly reduced in these subjects (t = 2.34, P =.02). Headache associated with refractive errors was rarely identified in individuals with refractive errors. In those with chronic headache, proper correction of refractive errors significantly improved headache complaints and did so primarily by decreasing the frequency of headache episodes.

Background Oxygen is recommended for the treatment of acute cluster headache attacks. However, it is not available worldwide. Methods The International Headache Society performed a survey among its national member societies on the availability and the restrictions for oxygen in the treatment of cluster headache. Results Oxygen is reimbursed in 50% of all countries responding ( n = 22). There are additional restrictions in the reimbursement of the facial mask and with respect to age. Conclusion Oxygen for the treatment of cluster headache attack is not reimbursed worldwide. Headache societies should pressure national/public health authorities to reimburse oxygen for cluster headache in all countries.

Nonrhinologic headache in a tertiary rhinology practice.

Our goal was to determine the etiology of headache in patients who were referred for sinus evaluation but were found to have no evidence of rhinosinusitis on computed tomography (CT) of the sinuses and on endoscopic examination. Data were collected prospectively from 100 patients with headache but with normal sinus CT and endoscopic examination. Headache and 20-Item Sino-Nasal Outcomes Test (SNOT-20) scores of patients with the chief complaint of headache and who requested further neurologic evaluation (group I) were compared with the scores of patients who did not list headache as a significant symptom (group II) and with the scores of patients without headache (group III). The most common neurologic diagnosis for group I patients (n = 36) was migraine headaches (58%). These patients also had higher mean SNOT-20 scores (24 +/- 3.3) compared to group II patients with mild headache (14.6 +/- 2.3) or group III patients without headache (12.4 +/- 2.1). Migraine was the most common type of headache in patients with normal sinus CT treated for presumed rhinosinusitis as the cause of the headache. Patients with headache as their chief complaint that required further neurologic evaluation had overall higher SNOT-20 scores than nonheadache patients, indicating greater disability of their overall quality of life index.

Headaches occur frequently and thus are a key component of sociocentric medical education. To study headaches among students of medicine and psychology in a single university. This was a questionnaire-based survey of a cohort of students of medicine and psychology. The overall lifetime prevalence of headache was 98% and over the last year, 91%. Tensional headache accounted for 59% and migraine 22% in medicine; and 48.5% and 32% respectively in psychology. Forty-five percent reported that headaches had a variable sporadic impact on their productivity. The self-medication rate was 77%. Thirty-six percent reported worsening since admission to the university. The prevalence of headaches was very high. Tension-type headaches predominated in males and migraine in females. Tension-type was more frequent among medical students than among psychology students; migraine was more frequent in psychology (more females) than in medicine. Both kinds of students reported that headaches caused low interference with daily activities. The students reported that their symptoms had worsened since admission to the university.

Point of impact: the effect of size and speed on puncture mechanics

2016-01-01

The use of high-speed puncture mechanics for prey capture has been documented across a wide range of organisms, including vertebrates, arthropods, molluscs and cnidarians. These examples span four phyla and seven orders of magnitude difference in size. The commonality of these puncture systems offers an opportunity to explore how organisms at different scales and with different materials, morphologies and kinematics perform the same basic function. However, there is currently no framework for combining kinematic performance with cutting mechanics in biological puncture systems. Our aim here is to establish this framework by examining the effects of size and velocity in a series of controlled ballistic puncture experiments. Arrows of identical shape but varying in mass and speed were shot into cubes of ballistic gelatine. Results from high-speed videography show that projectile velocity can alter how the target gel responds to cutting. Mixed models comparing kinematic variables and puncture patterns indicate that the kinetic energy of a projectile is a better predictor of penetration than either momentum or velocity. These results form a foundation for studying the effects of impact on biological puncture, opening the door for future work to explore the influence of morphology and material organization on high-speed cutting dynamics.

New daily persistent headache.

PubMed

Rozen, Todd D

2010-01-01

New daily persistent headache (NDPH) is a unique form of chronic daily headache (CDH) which is marked by a daily headache from onset, typically occurring in individuals without a significant prior history of headaches. There are two subforms of NDPH: one which is self-limited and normally goes away without therapy, and a more chronic refractory form which is unresponsive to typical headache treatment strategies. The pathogenesis of NDPH is unknown but recent observations suggest a connection with cervical spine hypermobility and elevation of proinflammatory cytokines in the cerebrospinal fluid (CSF). Recognized triggers for NDPH include infection, stressful life events, and surgical procedures. Clinically, NDPH is characterized by continuous head pain of mild to severe intensity. Migrainous symptoms are common. The syndrome appears to affect women in their teens and 20s, while males develop NDPH later in life in their 50s or 60s. There are no recognized treatments for this condition, although treatment options will be discussed. Secondary mimics of NDPH will also be touched upon in this chapter. Copyright © 2011 Elsevier B.V.

2016-06-01

Headache attributed to ingestion of a cold stimulus (ICHD-3 beta 4.5.1) is also known as ice cream headache (ICH). This cross-sectional epidemiological study included 283 students (10-14-year-olds) attending a grammar school in Germany, their parents (n = 401), and 41 teachers. A self-administered questionnaire was used to analyze the prevalence and characteristics of ICH based on the ICHD classification. Additionally, the association between ICH and other headaches was investigated in students and parents. Prevalence of ICH in students was 62 % without gender difference. In adults, only 36 % of females and 22 % of males reported ICH. There was an increased risk for ICH in students when mother (OR 10.7) or father (OR 8.4) had ICH. Other headaches in parents had no influence on the prevalence of ICH in students. However, in the groups of students and parents itself there was a highly significant association between ICH and other headaches (students: OR 2.4, mothers: OR 2.9, fathers: OR 6.8). There was a decreased risk for ICH when parents and students had no headache at all (OR < 0.4). ICH in students clearly shows a familial disposition by both father and mother. There was also an association between ICH and other headaches within the student and adult groups. The absence of headache history seems to be a protective factor for ICH.

The aim of this study was to compare the frequency of headache between Chagasic and Non-chagasic women. The cross-sectional study comprised 647 female > or = 40 years old, Chagasic (n = 362) and Controls (n = 285) at a Brazilian University Hospital. Chagasic were classified as Cardiac (n = 179), Megas (n = 58) or Indeterminate (n = 125) clinical forms. Headache was ascertained according to Headache International Society diagnostic criteria. The age (57.0 +/- 11.3 versus 57.3 +/- 10.4 years), and the percentage of white women (75.8% versus 77.1%) were similar between Chagasic and Controls, respectively. Headache was more prevalent among Chagasic (32.9%) than Controls (16.1%), mainly in Cardiac form (odds ratio, 2.41; 95% confidence interval, 1.38-4.23), phenomenon possibly related to parasympathetic denervation and cerebral vessels changes.

The history of craniotomy for headache treatment.

Both the history of headache and the practice of craniotomy can be traced to antiquity. From ancient times through the present day, numerous civilizations and scholars have performed craniotomy in attempts to treat headache. Today, surgical intervention for headache management is becoming increasingly more common due to improved technology and greater understanding of headache. By tracing the evolution of the understanding of headache alongside the practice of craniotomy, investigators can better evaluate the mechanisms of headache and the therapeutic treatments used today.

Headache related to airplane flights is rare. We describe a 37-year-old female patient with multiple intense, jabbing headache episodes over the last 3 years that occur exclusively during airplane flights. The pain manifests during take-off and landing, and is located always in the left retro-orbital and frontotemporal area. It is occasionally accompanied by dizziness, but no additional symptoms occur. Pain intensity diminishes and disappears after 15-20 min. Apart from occasional dizziness, no other symptoms occur. The patient has a history of tension-type headache and polycystic ovaries. Blood tests and imaging revealed no abnormalities. Here, we present the first case in Greece. We review the current literature on this rare syndrome and discuss on possible pathophysiology and the investigation of possible co-factors such as anxiety and depression.

A case report with review of the literature. To highlight the need for careful magnetic resonance imaging evaluation for the presence of incidental lumbosacral dural anomalies before attempting caudal epidural interventions. Pre-emptive analgesia through the caudal epidural route provides good postoperative pain relief in spine surgeries. Several precautions have been advised in the literature. Presence of sacral-dural ectasia should be considered a relative contraindication for this procedure. A 50-year old woman underwent posterior instrumented spinal fusion for L4-L5 spondylolisthesis under general anesthesia. She received single shot caudal epidural analgesia at the start of the procedure. After complete emergence from anesthesia, she had complete motor and sensory loss below the T12 spinal level, which reversed to normal neurology in 6 hours. Retrospective evaluation of the patient's magnetic resonance imaging showed an ectatic, low lying lumbosacral dural sac which had been overlooked in the initial evaluation. The drugs given by the caudal route have been accidentally administered into the thecal sac causing a brief period of neurologic deficit. This unexpected complication has been reported only in the pediatric literature before. It is important to look for the presence of lumbosacral dural anomalies before planning caudal epidural injections in adults also. Sacral dural ectasia and other lumbosacral anomalies must be recognized as contraindications for caudal epidural pre-emptive analgesia for spine surgery. Other modes of postoperative pain relief should be tried in these patients.

To describe headaches in patients with epilepsy and try to identify relations between epileptic seizures and headaches. Cross-sectional study, with 304 patients from the epilepsy out-patient section of University Hospital of Federal University of Alagoas (Brazil) between February 2007 and February 2008. The presence of headaches and their relationships with the epileptic seizures were analyzed. Frequent seizures were associated with a greater tendency of occurrence of headaches (odds ratio=1.6 times, p=0.077). Headaches occurred in 66.1% of the cases. The highest occurrence was of migraine (32.9% of the patients), followed by tension-type headaches (9.2%). Two syndromes with a continuum epilepsy-migraine in the same seizure are worth mentioning: migralepsy in 6.6% and epilepgraine in 10.2% of the patients with epilepsy. A high prevalence of headaches in patients with epilepsy was observed, with emphasis on hybrid crises of epilepsy and migraine. Copyright © 2013 British Epilepsy Association.

It is widely recognized that weather changes can trigger headache onset. Most people who develop headaches choose to self-medicate rather than visit a hospital or clinic. We investigated the association between weather and headache onset using large-sample sales of the headache medicine, loxoprofen. We collected daily sales figures of loxoprofen and over-the-counter drugs over a 1-year period from a drugstore chain in western Shizuoka prefecture, Japan. To adjust for changes in daily sales of loxoprofen due to social environmental factors, we calculated a proportion of loxoprofen daily sales to over-the-counter drug daily sales. At the same time, we obtained weather data for the study region from the website of the Japan Meteorological Agency. We performed linear regression analysis to ascertain the association between weather conditions and the loxoprofen daily sales proportion. We also conducted a separate questionnaire survey at the same drugstores to determine the reason why people purchased loxoprofen. Over the study period, we surveyed the sale of hundreds of thousands of loxoprofen tablets. Most people purchased loxoprofen because they had a headache. We found that the sales proportion of loxoprofen increased when average barometric pressure decreased, and that precipitation, average humidity, and minimum humidity increased on loxoprofen purchase days compared to the previous day of purchases. This study, performed using a large dataset that was easy-to-collect and representative of the general population, revealed that sales of loxoprofen, which can represent the onset and aggravation of headache, significantly increased with worsening weather conditions.

Lumbar puncture opening pressure is not a reliable measure of intracranial pressure in children.

PubMed

Cartwright, Cathy; Igbaseimokumo, Usiakimi

2015-02-01

There is very little data correlating lumbar puncture pressures to formal intracranial pressure monitoring despite the widespread use of both procedures. The hypothesis was that lumbar puncture is a single-point measurement and hence it may not be a reliable evaluation of intracranial pressure. The study was therefore carried out to compare lumbar puncture opening pressures with the Camino bolt intracranial pressure monitor in children. Twelve children with a mean age of 8.5 years who had both lumbar puncture and intracranial pressure monitoring were analyzed. The mean lumbar puncture opening pressure was 22.4 mm Hg versus a mean Camino bolt intracranial pressure of 7.8 mm Hg (P < .0001). Lumbar puncture therefore significantly overestimates the intracranial pressure in children. There were no complications from the intracranial pressure monitoring, and the procedure changed the treatment of all 12 children avoiding invasive operative procedures in most of the patients. © The Author(s) 2014.

Variations in intracranial dural venous sinus anatomy have been widely reported in humans, but there have been no studies reporting this in dogs. The purpose of this retrospective study was to describe variations in magnetic resonance (MR) venographic anatomy of the dorsal dural venous sinus system in a sample population of dogs with structurally normal brains. Medical records were searched for dogs with complete phase contrast, intracranial MR venograms and a diagnosis of idiopathic epilepsy. Magnetic resonance venograms were retrieved for each dog and characteristics of the dorsal dural sinuses, symmetry of the transverse sinuses and other anatomic variations were recorded. A total of 51 dogs were included. Transverse sinus asymmetry was present in 58.8% of the dogs, with transverse sinus hypoplasia seen in 39.2%, and aplasia in 23.5% of dogs. For 70.6% of dogs, at least one anatomic variation in the dorsal sagittal sinus was observed, including deviation from the midline (33.3%) and collateral branches from either the dorsal sagittal sinus or dorsal cerebral veins (54.9%). In 5 dogs (9.8%) a vessel was also identified running from the proximal transverse sinus to the distal sigmoid sinus, in a similar location to the occipital sinus previously reported in children. Findings from this study indicated that, as in humans, anatomic variations are common in the intracranial dural venous sinus system of dogs. These anatomic variations should be taken into consideration for surgical planning or diagnosis of cerebrovascular disease. © 2013 Veterinary Radiology & Ultrasound.

Background Headache disorders are widespread and disabling. They are common in Georgia, especially headache on ≥15 days/month (HA ≥ 15), but there are no headache services. Objective We established headache services meeting local needs, investigating feasibility, consumer uptake and satisfaction, and cost, with an exit strategy bequeathing effective, self-sustaining services that could be rolled out nationwide. Methods We created headache centres in Tbilisi and Gori offering free expert care for three visits over three months, and affordable medication thereafter. The primary outcome measure was the percentage of patients using the service beyond the free period - a measure of both satisfaction and sustainability. Results Of 1,445 patients (age 43.7 ± 12.4 years; 10.5% male), 49.8% had episodic migraine, 22.5% episodic tension-type headache, 25.7% HA ≥ 15 (24.5% overusing medication) and 2.0% trigeminal autonomic cephalalgias. Only 454 (31.4%) and 51 (3.5%) returned for second and third visits; in these, headache improved and treatment costs decreased. As information about the service spread, five other headache clinics opened in Tbilisi and Kutaisi (western Georgia). Pharmaceutical companies reduced prices (sumatriptan 100 mg from US$7 to US$1). Conclusion The study failed to achieve its primary outcome, but sustainable headache services operating to international standards were successfully implemented nonetheless, with demand increasing.

[An atraumatic needle for the puncture of ports and pumps].

PubMed

Haindl, H; Müller, H

1988-10-17

Huber-point needles have been found to induce substantial coring during puncture of ports or pumps, which may lead to leakage or obturation of these devices. Therefore, different types of cannulas were tested in order to evaluate their applicability for this purpose. Pencil-point needles led to increased pain during puncture and thus seemed unsuitable. A newly developed port-cannula bent inwards within the length of the bevel ("protected bevel") and proved to be definitely noncoring during electron microscopy. Consequently the force required to introduce this needle was reduced by 50% in comparison with the Huber-type needle. In addition, this cannula allowed up to 3000 punctures of one port without leakage and, thus, correspondingly therefore relevantly increased the durability of this device.

Academic aptitude as a predictor of headache proneness during college: could headache be an outcome of low test scores?

PubMed

Hovanitz, Christine A; Thatcher, Dawn Lindsay

2012-03-01

Academic work as well as compensated employment has been found adversely associated with frequent headache; headache remains a costly disorder to the person and to society. However, little is known of factors--other than prior headache complaints--that may predict headache frequency over extended periods of time. Based on previous research, effortful task engagement appears to be a contributing factor to headache onset. This suggests that relatively stable attributes that are likely to affect effort expenditure may predict headache frequency over long intervals. The goal of this study was to evaluate the predictability of headache proneness in college-attending students by college aptitude tests administered in high school. Five hundred undergraduate students enrolled in a large public, urban university completed a number of questionnaires. Official admissions records of the college aptitude tests ACT (an acronym for the original test name, the American College Testing), SAT (the Scholastic Aptitude Test), and GPA (grade point average) were obtained and compared to the report of headache frequency. The ACT test mathematics predicted headache proneness in the hypothesized direction, while the ACT English test provided conflicting data; some evidence of gender differences was suggested. While nearly all research on headache and work effectiveness has considered headache to be a cause of reduced efficiency or productivity, this study suggests that a factor which presumably affects the ease of work completion (e.g., scholastic aptitude) may predict headache, at least in some cases within the "work" environment of academia.

We present a detailed study of the effects of mesh refinement boundaries on the convergence and stability of simulations of black hole spacetimes. We find no technical problems. In our applications of this technique to the evolution of puncture initial data, we demonstrate that it is possible to simulaneously maintain second order convergence near the puncture and extend the outer boundary beyond 100M, thereby approaching the asymptotically flat region in which boundary condition problems are less difficult.

Combat-related headache and traumatic brain injury.

PubMed

Waung, Maggie W; Abrams, Gary M

2012-12-01

Post-traumatic headache is a commonly described complication of traumatic brain injury. Recent studies highlight differences between headache features of combat veterans who suffered traumatic brain injury compared to civilians. Not surprisingly, there is a higher rate of associated PTSD and sleep disturbances among veterans. Factors of lower socioeconomic status, rank, and multiple head injuries appear to have a similar effect on post-traumatic headache in combat-related traumatic brain injury. Areas of discordance in the literature include the effect of prolonged loss of consciousness and the prevalence of specific headache phenotypes following head trauma. To date, there have been no randomized trials of treatment for post-traumatic headache. This may be related to the variability of headache features and uncertainty of pathophysiologic mechanisms. Given this lack of data, many practitioners follow treatment guidelines for primary headaches. Additionally, because of mounting data linking PTSD to post-traumatic headache in combat veterans, it may be crucial to choose multimodal agents and take a multidisciplinary approach to combat-related headache.

Headache is one of the most common chief complaints seen in the pediatrician's office. Oftentimes, identifying the etiology of headache and differentiating primary and secondary causes can present a diagnostic conundrum. Understanding the most common causes of primary and secondary headache is vital to making a correct diagnosis. Here we review the typical presentations of the most common primary headache disorders and the approach to evaluation of the pediatric patient presenting with headache. Diagnostic workup, including the key features to elicit on physical examination, when to order head imaging, and the use of other ancillary tests, is discussed. Current treatment modalities and their indications are reviewed. We will also describe some of the new, emerging therapies that may alter the way we manage headache in the pediatric population. Headache can, at times, be a frustrating symptom seen in the pediatrician's office, but here we hope to better elucidate the approach to evaluation, management, and treatment as well as provide some hope in regards to more effective upcoming therapies.

To investigate the association between uncorrected or miscorrected refractive errors in children and headache, and to determine whether correction of refractive errors contributes to headache resolution. Results of ophthalmic examination, including refractive error, were recorded at initial visit for headache. If resolution of headache on subsequent visits was not documented, a telephone call was placed to their caregivers to inquire whether headache had resolved. Of the 158 patients, 75.3% had normal or unchanged eye examinations, including refractions.Follow-up data were available for 110 patients. Among those, 32 received new or changed spectacle correction and 78 did not require a change in refraction.Headaches improved in 76.4% of all patients, whether with (71.9%) or without (78.2%) a change in refractive correction. The difference between these two groups was not statistically significant (P = .38). Headaches in children usually do not appear to be caused by ophthalmic disease, including refractive error. The prognosis for improvement is favorable, regardless of whether refractive correction is required. Copyright 2014, SLACK Incorporated.

Secondary headaches attributed to arterial hypertension

2013-01-01

Mild (140 to 159/90 to 99 mmHg) or moderate (160 to 179/100 to 109 mmHg) chronic arterial hypertension does not appear to cause headache. Whether moderate hypertension predisposes patients to headache at all remains controversial, but there is little evidence that it does. Ambulatory blood pressure monitoring in patients with mild and moderate hypertension has shown no convincing relationship between blood pressure fluctuations over a 24-hour period and presence or absence of headache. However, headaches are associated to various disorders that lead to abrupt, severe, and paroxysmal elevations in blood pressure. In this paper, the secondary headaches attributed to acute crises of hypertension and the criteria for diagnosing each of them have been reviewed. These are headaches attributed to pheochromocytoma, hypertensive crisis without encephalopathy, hypertensive encephalopathy, pre-eclampsia, eclampsia, and acute pressure response to exogenous agents.

1999-02-01

This article presents an overview of the epidemiology and pathophysiology of posttraumatic headache. It reviews definitions of mild head injury (MHI), mild traumatic brain injury (MTBI), and concussion, and discusses the confusion that often occurs with these terms. Headache types and their pathophysiology are examined in detail. Just as the exact pathophysiology is unknown for migraine and other types of headache, the exact pathophysiology of headache after trauma is also still unknown in many cases. Possible connections between head or neck injuries and headache are reviewed, as well as hypothesized neurochemical changes that may occur in both migraine and traumatic brain injury (TBI). Psychological and legal factors are also considered.

Caffeine and headache: specific remarks.

PubMed

Espinosa Jovel, C A; Sobrino Mejía, F E

Caffeine is the most widely used psychostimulant worldwide. Excessive caffeine consumption induces a series of both acute and chronic biological and physiological changes that may give rise to cognitive decline, depression, fatigue, insomnia, cardiovascular changes, and headache. Chronic consumption of caffeine promotes a pro-nociceptive state of cortical hyperexcitability that can intensify a primary headache or trigger a headache due to excessive analgesic use. This review offers an in-depth analysis of the physiological mechanisms of caffeine and its relationship with headache. Copyright © 2014 Sociedad Española de Neurología.

Minimally invasive spine (MIS) surgery utilizing tubular retractors has become an increasingly popular approach for decompression in the lumbar spine. However, a better understanding of appropriate indications, efficacious surgical techniques, limitations, and complication management is required to effectively teach the procedure and to facilitate the learning curve. To describe our experience and recommendations regarding tubular surgery for lumbar disc herniations, foraminal compression with unilateral radiculopathy, lumbar spinal stenosis, synovial cysts, and dural repair. We reviewed our experience between 2008 and 2014 to develop a step-by-step description of the surgical techniques and complication management, including dural repair through tubes, for the 4 lumbar pathologies of highest frequency. We provide additional supplementary videos for dural tear repair, laminotomy for bilateral decompression, and synovial cyst resection. Our overview and complementary materials document the key technical details to maximize the success of the 4 MIS surgical techniques. The review of our experience in 331 patients reveals technical feasibility as well as satisfying clinical results, with no postoperative complications associated with cerebrospinal fluid leaks, 1 infection, and 17 instances (5.1%) of delayed fusion. MIS surgery through tubular retractors is a safe and effective alternative to traditional open or microsurgical techniques for the treatment of lumbar degenerative disease. Adherence to strict microsurgical techniques will allow the surgeon to effectively address bilateral pathology while preserving stability and minimizing complications.

Headache is the most common symptom of Chiari 1 malformation, a condition characterized by the herniation of cerebellar tonsils through the foramen magnum. However, the headache pattern of cases with Chiari 1 malformations is not well defined in the literature, especially in children. The aim of this retrospective chart review was to evaluate the frequency and the characteristics of headache in children with Chiari 1 malformation at initial evaluation and during follow up. Forty-five cases with tonsillar ectopia were selected among 9947 cases under 18 years of age who underwent neuroimaging between 2002 and 2010. A semistructured clinical interview (mean follow-up: 5.2 years) was conducted. Headache was classified according to the second edition of the International Classification of Headache Disorders. Possible associations between clinical picture, in particular headache pattern, but also other signs and symptoms attributable to Chiari 1 malformation, and the extent of tonsillar ectopia were found for 3 different groups: those with borderline (<5 mm, N = 12), mild (5-9 mm, N = 27), and severe tonsillar ectopia (≥10 mm, N = 6), respectively. Twenty-four out of 33 (73%) cases with Chiari 1 malformation complained of headache, and 9/33 (27%) of those patients (5 with mild and 4 with severe tonsillar ectopia) reported headache attributed to Chiari 1 malformation. In our studied pediatric population, the most common symptom for cases diagnosed with Chiari 1 malformation was headache, and headache attributed to Chiari 1 malformation was the most common headache pattern in patients with Chiari 1 malformation. The presence of headache attributed to Chiari 1 malformation along with 3 other signs or symptoms of Chiari 1 malformation were highly predictive of severe tonsillar ectopia. © 2014 American Headache Society.

Purpose. To assess the efficacy and safety of the Exoseal vascular closure device for antegrade puncture of the femoral artery. Methods. In a prospective study from February 2011 to January 2012, a total of 93 consecutive patients received a total of 100 interventional procedures via an antegrade puncture of the femoral artery. An Exoseal vascular closure device (6F) was used for closure in all cases. Puncture technique, duration of manual compression, and use of compression bandages were documented. All patients were monitored by vascular ultrasound and color-coded duplex sonography of their respective femoral artery puncture site within 12 to 36more » h after angiography to check for vascular complications. Results. In 100 antegrade interventional procedures, the Exoseal vascular closure device was applied successfully for closure of the femoral artery puncture site in 96 cases (96 of 100, 96.0 %). The vascular closure device could not be deployed in one case as a result of kinking of the vascular sheath introducer and in three cases because the bioabsorbable plug was not properly delivered to the extravascular space adjacent to the arterial puncture site, but instead fully removed with the delivery system (4.0 %). Twelve to 36 h after the procedure, vascular ultrasound revealed no complications at the femoral artery puncture site in 93 cases (93.0 %). Minor vascular complications were found in seven cases (7.0 %), with four cases (4.0 %) of pseudoaneurysm and three cases (3.0 %) of significant late bleeding, none of which required surgery. Conclusion. The Exoseal vascular closure device was safely used for antegrade puncture of the femoral artery, with a high rate of procedural success (96.0 %), a low rate of minor vascular complications (7.0 %), and no major adverse events.« less

Benign Headache Management in the Emergency Department.

Headache is a common complaint managed in the emergency department (ED), with emergency physicians focusing on evaluation for life-threatening conditions while treating pain and nausea. This review evaluates the treatment of benign, primary headaches in the ED, with recommendations provided based on the literature. Headaches are a major cause of disability in the United States and a common condition managed in the ED. The primary objectives of emergency evaluation of these patients include evaluation for a life-threatening, secondary cause of headache, with treatment of primary headaches. Close evaluation for a secondary cause of headache include consideration of red flags and focused neurologic examination. The diagnosis of primary headaches is clinical. Literature has evaluated medication efficacy in headache treatment, with antidopaminergic medications demonstrating high rates of efficacy when used in combination with nonsteroidal inflammatory drugs or acetaminophen. Dexamethasone can be used for the reduction of headache recurrence. If dehydration is present, intravenous fluids should be provided. Diphenhydramine is not recommended for analgesia but may reduce akathisia associated with prochlorperazine. Ketamine, propofol, and nerve blocks demonstrate promise. Triptan agents are also efficacious, provided absence of contraindications. Most patients are appropriate for discharge with pain improvement. A variety of medications is available for the treatment of primary headaches in the ED. Antidopaminergic agents demonstrate the highest efficacy and should be provided with acetaminophen and nonsteroidal inflammatory drugs. Dexamethasone may reduce headache recurrence. Other treatments include ketamine, propofol, and nerve blocks. Published by Elsevier Inc.

The interperiosteo-dural concept applied to the perisellar compartment: a microanatomical and electron microscopic study.

The dura mater has 2 dural layers: the endosteal layer (outer layer), which is firmly attached to the bone, and the meningeal layer (inner layer), which directly covers the brain. These 2 dural layers join together in the middle temporal fossa or the convexity and separate into the orbital, lateral sellar compartment (LSC), or spinal epidural space to form the extradural neural axis compartment (EDNAC). The aim of this work was to anatomically verify the concept of the EDNAC by using electron microscopy. The authors studied the cadaveric heads obtained from 13 adults. Ten of the specimens (or 20 perisellar areas) were injected with colored latex and fixed in formalin. They carefully removed each brain to allow a superior approach to the perisellar area. The 3 other specimens were studied by microscopic and ultrastructural methods to describe the EDNAC in the perisellar area. Special attention was paid to the dural layers surrounding the perisellar area. The authors studied the anatomy of the meningeal architecture of the LSC, the petroclival venous confluence, the orbit, and the trigeminal cave. After dissection, the authors took photographs of the dural layers with the aid of optical magnification. The 3 remaining heads, obtained from fresh cadavers, were prepared for electron microscopic study. The EDNAC is limited by the endosteal layer and the meningeal layer and contains fat and/or venous blood. The endosteal layer and meningeal layer were not identical on electron microscopy; this finding can be readily related to the histology of the meninges. In this study, the authors demonstrated the existence of the EDNAC concept in the perisellar area by using dissected cadaveric heads and verified the reality of the concept of the meningeal layer with electron microscopy. These findings clearly demonstrated the existence of the EDNAC, a notion that has generally been accepted but never demonstrated microscopically.

Objective To evaluate the presence, localization, and specificity of structural hypothalamic and whole brain changes in cluster headache and chronic paroxysmal hemicrania (CPH). Methods We compared T1-weighted magnetic resonance images of subjects with cluster headache (episodic n = 24; chronic n = 23; probable n = 14), CPH ( n = 9), migraine (with aura n = 14; without aura n = 19), and no headache ( n = 48). We applied whole brain voxel-based morphometry (VBM) using two complementary methods to analyze structural changes in the hypothalamus: region-of-interest analyses in whole brain VBM, and manual segmentation of the hypothalamus to calculate volumes. We used both conservative VBM thresholds, correcting for multiple comparisons, and less conservative thresholds for exploratory purposes. Results Using region-of-interest VBM analyses mirrored to the headache side, we found enlargement ( p < 0.05, small volume correction) in the anterior hypothalamic gray matter in subjects with chronic cluster headache compared to controls, and in all participants with episodic or chronic cluster headache taken together compared to migraineurs. After manual segmentation, hypothalamic volume (mean±SD) was larger ( p < 0.05) both in subjects with episodic (1.89 ± 0.18 ml) and chronic (1.87 ± 0.21 ml) cluster headache compared to controls (1.72 ± 0.15 ml) and migraineurs (1.68 ± 0.19 ml). Similar but non-significant trends were observed for participants with probable cluster headache (1.82 ± 0.19 ml; p = 0.07) and CPH (1.79 ± 0.20 ml; p = 0.15). Increased hypothalamic volume was primarily explained by bilateral enlargement of the anterior hypothalamus. Exploratory whole brain VBM analyses showed widespread changes in pain-modulating areas in all subjects with headache. Interpretation The anterior hypothalamus is enlarged in episodic and chronic cluster headache and possibly also in probable cluster

The relationship of the frequency of temple headache to signs and symptoms of temporomandibular disorders (TMD) was investigated in a subset of a larger convenience sample of community TMD cases. The study sample included: 86 painful TMD, non-headache subjects; 309 painful TMD subjects with varied frequency of temple headaches; and 149 subjects without painful TMD or headache for descriptive comparison. Painful TMD included Research Diagnostic Criteria (RDC) diagnoses of myofascial pain, TMJ arthralgia and TMJ osteoarthritis. Mild to moderate intensity temple headaches were classified by frequency using criteria based on the ICHD-II classification of TTH. Outcomes included TMD signs and symptoms (pain duration, pain intensity, number of painful masticatory sites on palpation, mandibular range of motion), PPTs and temple headache resulting from masticatory provocation tests. Trend analyses across the painful TMD groups showed a substantial trend for aggravation of all of the TMD signs and symptoms associated with increased frequency of the temple headaches. In addition, increased headache frequency showed significant trends associated with reduced PPTs and reported temple headache with masticatory provocation tests. In conclusion, these findings suggest that these headaches may be TMD-related, as well as a possible role for peripheral and central sensitization in TMD patients. PMID:21196079

An in vitro biomechanical study for rabbit lumbar functional spinal units (FSUs) using a robot-based spine testing system. To elucidate the effect of annular puncture with a 16 G needle on mechanical properties in flexion/extension, axial rotation, and lateral bending. Needle puncture of the intervertebral disk has been shown to alter mechanical properties of the disk in compression, torsion, and bending. The effect of needle puncture in FSUs, where intact spinal ligaments and facet joints may mitigate or amplify these changes in the disk, on spinal motion segment stability subject to physiological rotations remains unknown. Rabbit FSUs were tested using a robot testing system whose force/moment and position precision were assessed to demonstrate system capability. Flexibility testing methods were developed by load-to-failure testing in flexion/extension, axial rotation, and lateral bending. Subsequent testing methods were used to examine a 16 G needle disk puncture and No. 11 blade disk stab (positive control for mechanical disruption). Flexibility testing was used to assess segmental range-of-motion (degrees), neutral zone stiffness (N m/degrees) and width (degrees and N m), and elastic zone stiffness before and after annular injury. The robot-based system was capable of performing flexibility testing on FSUs-mean precision of force/moment measurements and robot system movements were <3% and 1%, respectively, of moment-rotation target values. Flexibility moment targets were 0.3 N m for flexion and axial rotation and 0.15 N m for extension and lateral bending. Needle puncture caused significant (P<0.05) changes only in flexion/extension range-of-motion and neutral zone stiffness and width (N m) compared with preintervention. No. 11 blade-stab significantly increased range-of-motion in all motions, decreased neutral zone stiffness and width (N m) in flexion/extension, and increased elastic zone stiffness in flexion and lateral bending. These findings suggest that

A quantum mechanical system on a punctured surface modeled on hyperbolic space has always been an important subject of research in mathematics and physics. This corresponding quantum system is governed by the Schrödinger equation whose solutions are the Maass waveforms. Spectral studies on these Maass waveforms are known to contain both continuous and discrete eigenvalues. The discrete eigenfunctions are usually called the Maass Cusp Forms (MCF) where their discrete eigenvalues are not known analytically. We introduce a numerical method based on Hejhal and Then algorithm using GridMathematica for computing MCF on a punctured surface with three cusps namely the triplymore » punctured two-sphere. We also report on a pullback algorithm for the punctured surface and a point locater algorithm to facilitate the complete pullback which are essential parts of the main algorithm.« less

The purpose of this retrospective multicenter study was to evaluate the use and the self-perceived efficacy and tolerability of pharmacological and non-pharmacological treatments in children and adolescents with primary headaches. Study of a cohort of children and adolescents diagnosed with primary headache, consecutively referred to 13 juvenile Italian Headache Centers. An ad hoc questionnaire was used for clinical data collection. Among 706 patients with primary headaches included in the study, 637 cases with a single type of headache (migraine 76% - with and without aura in 10% and 67% respectively; tension-type headache 24%) were selected (mean age at clinical interview: 12 years). Acetaminophen and non-steroidal anti-inflammatory drugs (in particular ibuprofen) were commonly used to treat attacks, by 76% and 46% of cases respectively. Triptans were used overall by 6% of migraineurs and by 13% of adolescents with migraine, with better efficacy than acetaminophen and non-steroidal anti-inflammatory drugs. Preventive drugs were used by 19% of migraineurs and by 3% of subjects with tension-type headache. In migraineurs, flunarizine was the most frequently used drug (18%), followed by antiepileptic drugs (7%) and pizotifen (6%), while cyproheptadine, propanolol and amitriptyline were rarely used. Pizotifen showed the best perceived efficacy and tolerability. Melatonin and nutraceuticals were used by 10% and 32% of subjects, respectively, both for migraine and tension-type headache, with good results in terms of perceived efficacy and tolerability. Non-pharmacological preventive treatments (i.e. relaxation techniques, biofeedback, cognitive-behavioral therapy, acupuncture) were used only by 10% of cases (migraine 9%, tension-type headache 15%). Non-steroidal anti-inflammatory drugs, especially ibuprofen, should be preferred to acetaminophen for acute attacks of migraine or tension-type headache, because they were usually more effective and well tolerated.

We studied the biofeedback treatment of migraine headaches, attempting to control for some of the methodological limitations of previous work. Seven individuals suffering from migraine headache were trained in the usual finger warming procedure with the omission of autogenic phrases. Additionally, to control for placebo-expectance effects, three of these subjects received training in finger cooling prior to warming. With training in finger warming, headache activity was substantially reduced. In contrast, headache activity either remained at base line levels or increased during training in cooling despite positive therapeutic expectations. The results of this study indicate that finger temperature warming, without autogenic training, is effective in reducing migraine activity, independent of suggestion effects.

2013-12-23

At present new daily persistent headache is just a group of conditions that are connected based on the temporal profile of their mode of onset. If new daily persistent headache is a true distinct syndrome like migraine then we need to start to define subtypes that have specific effective treatments such has been noted for migraine sub-forms. We present what we believe is the first recognized subtype of new daily persistent headache that which starts with a thunderclap headache onset. A patient presented with a 13 month history of a daily headache from onset which initiated as a thunderclap headache along with persistent acalculia. All neuroimaging studies for secondary causes were negative. Nimodipine rapidly and completely alleviated her headache and associated neurologic symptoms. We propose that this subtype of new daily persistent headache is caused by a very rapid increase in CSF tumor necrosis factor alpha levels leading to cerebral artery vasospasm with a subsequent thunderclap headache, then continuous or near continuous cerebral artery vasospasm leading to a persistent daily headache. Nimodipine which not only inhibits cerebral artery vasospasm but also tumor necrosis factor alpha production appears to be a specific treatment for this distinct subtype of new daily persistent headache.

Laughing is recognized as a provoking factor for headache, certainly underestimated among the general population and few cases have been published to date. We report a single case of severe headache, provoked almost exclusively by outbursts of laughing, where venous magnetic resonance imaging revealed the presence of giant Pacchioni granulations in both right and transverse sinuses. Reviewing published cases of laughing headache, we discuss possible mechanisms of pain and the role of giant Pacchionian granulations. © 2013 American Headache Society.

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

ABSTRACT Objective To evaluate inflammatory reaction, fibrosis and neovascularization in dural repairs in Wistar rats using four techniques: simple suture, bovine collagen membrane, silicon mesh and silicon mesh with suture. Methods Thirty Wistar rats were randomized in five groups: the first was the control group, submitted to dural tear only. The others underwent durotomy and simple suture, bovine collagen membrane, silicon mesh and silicon mesh with suture. Animals were euthanized and the spine was submitted to histological evaluation with a score system (ranging from zero to 3) for inflammation, neovascularization and fibrosis. Results Fibrosis was significantly different between simple suture and silicon mesh (p=0.005) and between simple suture and mesh with suture (p=0.015), showing that fibrosis is more intense when a foreign body is used in the repair. Bovine membrane was significantly different from mesh plus suture (p=0.011) regarding vascularization. Inflammation was significantly different between simple suture and bovine collagen membrane. Conclusion Silicon mesh, compared to other commercial products available, is a possible alternative for dural repair. More studies are necessary to confirm these findings. PMID:26761555

Epidemiology of chronic daily headache.

Daily or near-daily headache is a widespread problem in clinical practice. The general term of chronic daily headache (CDH) encompasses those primary headaches presenting more than 15 days per month and lasting more than 4 hours per day. CDH includes transformed migraine (TM), chronic tension-type headache (CTTH), new daily persistent headache (NDPH), and hemicrania continua (HC). Around 40% of patients attending a specialized headache clinic meet CDH diagnostic criteria, of which 80% are women. In these clinics about 60% of patients suffer from TM, 20% from CTTH, and 20% meet NDPH criteria. Most, some 80%, overuse symptomatic medications. One should be very cautious on extrapolating these numbers to the general population. CDH prevalence in the general population seems to be around 4% to 5% (up to 8% to 9% for women). Regarding the prevalence of CDH subtypes, NDPH is rare (0.1%), whereas the prevalence of TM (1.5% to 2%) and CTTH (2.5% to 3%) is clearly higher. In contrast to data from specialized clinics, only around a quarter of CDH subjects in the general population overuse analgesics; the prevalence of CDH subjects with analgesic overuse being 1.1% to 1.9% of the general population. Most of these patients with analgesic overuse are TM patients.

Straube, A

Episodic headache of the tension type is the most prevalent primary headache with a lifetime prevalence of about 78 %. Clinical characteristics are a dull, moderate, holocephalic headache without accompanying autonomic or vegetative symptoms. The episodic tension-type headache often lasts only 30 min up to a maximum of a few days. In contrast to this clinically often undemanding headache, chronic tension-type headache can cause considerable disability in patients. The 1-year prevalence is 1-3 % of the population. All therapy strategies combine nonpharmaceutical therapy such as education of the patient, regular aerobic exercise, and psychological treatment (e.g., Jacobson's progressive muscle relaxation etc.) with pharmaceutical treatment such as tricyclic antidepressants or combined serotonergic and noradrenergic antidepressants. Combination therapy has been proven to be more effective than singular strategies; however, the chronic tension-type headache still poses a therapeutic problem.

To evaluate reported headache prevalence among the general population and patients suffering from snoring and obstructive sleep apnoea syndrome (OSAS), a cross-sectional study was performed among those aged 30-64 years residing in Kopparberg county in central Sweden. Consecutive patients referred to the sleep laboratory in the catchment area who fulfilled objective diagnostic criteria (snorers = 448, OSAS = 324) and a random sample of the general population (n = 583) responded to the same questionnaire. Patients were selected following sleep apnoea screening with 100% specificity for both OSAS and snoring. Responders from the general population were divided into snorers or non-snorers on the basis of self-report. To validate the self-report question on snoring in the questionnaire, 50 males and 49 females, randomly selected from the sample of the general population, underwent sleep apnoea screening in their homes. Headache among both men and women was found to be more prevalent among heavy snorers and OSAS patients compared with the control group. Morning headache, in particular, was at least three times more common among male and female heavy snorers and OSAS patients then among the general population. Headache in the control group was more common among snorers than non-snorers. Among responders, 5% of the general population reported experiencing headache often or very often upon awakening. For the heavy snoring and OSAS groups, 18% reported experiencing headache often or very often upon awakening. The results indicate that headache is common among heavy snorers and OSAS patients regardless of gender.

Objectives. The effect of massage therapy on chronic nonmigraine headache was investigated. Methods. Chronic tension headache sufferers received structured massage therapy treatment directed toward neck and shoulder muscles. Headache frequency, duration, and intensity were recorded and compared with baseline measures. Results. Compared with baseline values, headache frequency was significantly reduced within the first week of the massage protocol. The reduction of headache frequency continued for the remainder of the study (P = .009). The duration of headaches tended to decrease during the massage treatment period (P = .058). Headache intensity was unaffected by massage (P = .19). Conclusions. The muscle-specific massage therapy technique used in this study has the potential to be a functional, nonpharmacological intervention for reducing the incidence of chronic tension headache.

2012-05-01

Although migraine (MH) and tension type headache (TTH) are the most common and important causes of recurrent headache in adolescents, they are poorly understood and not recognized by parents and teachers, delaying the first physician evaluation for correct diagnosis and management. The purpose of this study is to assess the knowledge about headache impact among the students of a Communication Private High School in Rimini city, and to evaluate the main different types of headaches interfering with school and social day activities. A self-administered questionnaire interview was given to students of the last 2 years of high school; ten items assessed the headache experience during the prior 12 months, especially during school time: the features and diagnosis of headaches types (based on the 2004 IHS criteria), precipitating factors, disability measured using the migraine disability assessment (MIDAS); therapeutic intervention. Out of the 60 students, 84 % experienced recurrent headache during the last 12 months. 79 % were females, aged 17-20 years; a family history was present in 74 % of headache students, in the maternal line; 45 % of subjects were identified as having MH and 27 % TTH; 25 % had morning headache and 20 % in the afternoon; fatigue, emotional stress and lack of sleep were the main trigger factors for headache, respectively in 86, 50 and 50 % of students; 92 % of headache students could not follow the lessons, could not participate in exercises and physical activity because of the headache; none had consulted a medical doctor and the 90 % of all students had never read, listened or watched television about headache. This study remarks on the need to promote headache educational programs, starting from high school, to increase communication between teachers-family-physician and patient-adolescents, with the goal to have an early appropriate therapeutic intervention, improvement of the quality of life and to prevent long-term headache disease in the

Stress and headache chronification.

Houle, Timothy; Nash, Justin M

2008-01-01

In this special section, the concept of stress has been linked to the chronification of headache and is considered to be one of several likely mechanisms for the progression of an otherwise episodic disorder to a chronic daily phenomenon. The present review discusses the concept of stress and describes the mechanisms through which stress could influence headache progression. The hypothesized mechanisms include stress serving as a unique trigger for individual attacks, as a nociceptive activator, and as a moderator of other mechanisms. Finally, the techniques used in the screening and management of stress are mentioned in the context of employing strategies for the primary, secondary, or tertiary prevention of headache progression.

2016-04-01

Patients with traumatic spinal cord injury (TSCI) often suffer from different types of pain. However, headaches after TSCI have not been studied. The aim of this article is to examine the occurrence of headache among patients with TSCI. This cross-sectional study included individuals with TSCI from 1997 to 2012 in Estonia. Patients with TSCI were interviewed via telephone. The interview was based on a questionnaire specifically designed to identify headache type using the International Classification of Headache Disorders, third edition (beta version). There were 73 patients with a mean age 37.1 ± 10.6 years. The mean time since TSCI was 7.5 ± 4.0 years. The most frequently mentioned pain was headache (71%), followed by back pain (60%) and pain in neck (44%).Headaches were more frequent after the trauma compared with the headaches before TSCI (71% vs 51%, ITALIC! p = 0.02). Headaches that arose after TSCI were not related to the concomitant brain injury ( ITALIC! p = 0.15). The occurrence of headache did not depend on the severity or the level of the TSCI.Eighty-five percent of patients had not contacted any physician and headache was not diagnosed. This is the first study that evidentially shows that headache is the most prevalent pain condition after TSCI. Despite this, the majority of patients never consult a physician, nor is their headache diagnosed or appropriately managed. This indicates that further studies are needed to provide evidence regarding the prevalence and causes of headache and its impact on quality of life. © International Headache Society 2015.

The clinician's approach to the management of headache.

Headache is a ubiquitous complaint, yet it is one that often elicits anxiety in both patients and physicians. When a patient presents with headache, the clinician must answer the following questions: (1) Is the headache "worrisome" (secondary to underlying disease)? (2) If the headache is benign, what type is it? (3) How is the acute headache best treated? and (4) How may future headaches be prevented? The following review is intended to aid primary care physicians in answering these questions. PMID:9549429

There are many treatment options in high-flow priapism. Those mentioned most often are watchful waiting, Doppler-guided compression, endovascular highly selective embolization, and surgery. We present a case of high-flow priapism in a 57-year-old man treated by percutaneous direct puncture embolization of a post-traumatic left cavernosal arteriovenous fistula using N-butyl-cyanoacrylate. Erectile function was preserved during a 12-month follow-up. No patients with percutaneous direct puncture embolization for high-flow priapism have been reported previously. Percutaneous direct puncture embolization is a potentially useful and safe method for management of high-flow priapism.

This report evaluates the efficacy of percutaneous needle puncture under sonographic guidance in treating lateral epicondylitis (tennis-elbow). Ultrasound-guided percutaneous needle puncture was performed on 76 patients who presented with persistent elbow pain. Under a local anesthetic and sonographic guidance, a needle was advanced into the calcification foci and the calcifications were mechanically fragmented. This was followed by a local injection of 25 mg prednisone acetate and 1% lidocaine. If no calcification was found then multiple punctures were performed followed by local injection of 25 mg prednisone acetate and 1% lidocaine. A visual analog scale (VAS) was used to evaluate the degree of pain pre-and posttreatment at 1 week to 24 weeks. Elbow function improvement and degree of self-satisfaction were also evaluated. Of the 76 patients, 55% were rated with excellent treatment outcome, 32% good, 11% average, and 3% poor. From 3 weeks posttreatment, VAS scores were significantly reduced compared with the pretreatment score (P<0.05) and continued to gradually decline up to 24 weeks posttreatment. Sonography demonstrated that the calcified lesions disappeared completely in 13% of the patients, were reduced in 61% of the patients, and did not change in 26% of the patients. Color Doppler flow signal used to assess hemodynamic changes showed a significant improvement after treatment in most patients. Ultrasound-guided percutaneous needle puncture is an effective and minimally invasive treatment for tennis elbow. Sonography can be used to accurately identify the puncture location and monitor changes.

Epilepsy and primary headaches are two of the most common neurologic conditions that share some common clinical characteristics, and can affect individuals of all age groups around the world. In recent years, the underlying pathophysiologic mechanisms potentially common to both headaches and epileptic seizures have been the subject of scrutiny. The objective of this study was to determine the frequencies and types of headaches in patients with epilepsy, and evaluate any temporal relationship with epileptic seizures. Demographic data, epilepsy durations, seizure frequencies, seizure types and antiepileptic medications used were captured of 349 patients who were followed up at our epilepsy outpatient clinic. Patients who experienced headaches were grouped based on the type of headaches and on whether their headaches occurred in the preictal, postictal or interictal period. Three hundred forty-nine patients (190 females, 159 males) were enrolled in the study. The patients' average age was 30.9±13.1 years, and average epilepsy duration was 13.5±10.9 years. The types of epileptic seizures were partial in 19.8% of patients, generalized in 57.9%, and secondary generalized in 20.3% of patients. Some 43.6% of the patients did not experience headaches, and 26.9% had migraine and 17.2% tension-type headaches. Headaches could not be classified in 12.3% of patients. The headaches occurred preictally in 9.6%, postictally in 41.6% and interictally in 8.6% of patients. The ratio of headaches was lower in male patients compared with females, and females experienced migraine-type headaches more frequently compared with males (p=0.006). Migraine-type headaches were less frequent a mong patients who experienced less than one seizure per year, but more frequent (p=0.017) among those who experienced more than one seizure per month, but less than one seizure per week. Migraine-type headaches were significantly more frequent (p=0.015) among patients receiving polytherapy compared with

Nummular headache update.

Nummular headache is characterized by head pain exclusively felt in a rounded or elliptical area, typically 1 to 6 cm in diameter. The pain remains confined to the same symptomatic area, which does not change in shape or size with time. The symptomatic area may be localized in any part of the head but mostly in the parietal region. Rarely, the disorder may be multifocal, each symptomatic area keeping all the characteristics of nummular headache. The pain is generally mild or moderate, commonly described as oppressive or stabbing, and lasting minutes, hours, or days, with a remitting or unremitting pattern. Superimposed on the baseline pain, there may be spontaneous or triggered exacerbations. During and between symptomatic periods, the affected area may show variable combinations of hypoesthesia, dysesthesia, paresthesia, tenderness, and trophic changes. Nummular headache emerges as a primary disorder with a clear-cut clinical picture developed in a unique topography.

External compression headache is defined as a headache caused by an external physical compression applied on the head. It affects about 4% of the general population; however, certain populations (e.g. construction workers and military personnel) with particular needs of headwear or helmet are at higher risk of developing this type of headache. External compression headache is poorly studied in relation to specific populations. This study aimed to investigate the prevalence and pattern of helmet-induced external compression headache among Danish military personnel of the Northern Jutland region in Denmark. Data acquisition was based on a custom-made questionnaire delivered to volunteers who used helmets in the Danish military service and who agreed to participate in this study. The military of the Northern Jutland region of Denmark facilitated recruitment of the participants. The questionnaires were delivered on paper and the collected (anonymous) answers (total 279) were used for further analysis. About 30% of the study participants reported headache in relation to wearing a military helmet. Headache was defined as a pressing pain predominantly in the front of the head with an average intensity of 4 on a visual analogue scale of 0 (no pain) to 10 (worst pain imaginable). It was also found that helmets with different designs influenced both the occurrence of headache and its characteristics. This study is the first to demonstrate the prevalence and pattern of compression headache among military personnel in North Jutland, Denmark. The findings of this study call for further attention to helmet-induced external compression headache and strategies to minimize the burden.

Aspirin is first-line treatment for migraine and episodic tension-type headache regardless of headache intensity.

(1) To establish whether pre-treatment headache intensity in migraine or episodic tension-type headache (ETTH) predicts success or failure of treatment with aspirin; and (2) to reflect, accordingly, on the place of aspirin in the management of these disorders. Stepped care in migraine management uses symptomatic treatments as first-line, reserving triptans for those in whom this proves ineffective. Stratified care chooses between symptomatic therapy and triptans as first-line on an individual basis according to perceived illness severity. We questioned the 2 assumptions underpinning stratified care in migraine that greater illness severity: (1) reflects greater need; and (2) is a risk factor for failure of symptomatic treatment but not of triptans. With regard to the first assumption, we developed a rhetorical argument that need for treatment is underpinned by expectation of benefit, not by illness severity. To address the second, we reviewed individual patient data from 6 clinical trials of aspirin 1000 mg in migraine (N = 2079; 1165 moderate headache, 914 severe) and one of aspirin 500 and 1000 mg in ETTH (N = 325; 180 moderate, 145 severe), relating outcome to pre-treatment headache intensity. In migraine, for headache relief at 2 hours, a small (4.7%) and non-significant risk difference (RD) in therapeutic gain favored moderate pain; for pain freedom at 2 hours, therapeutic gains were almost identical (RD: -0.2%). In ETTH, for headache relief at 2 hours, RDs for both aspirin 500 mg (-4.2%) and aspirin 1000 mg (-9.7%) favored severe pain, although neither significantly; for pain freedom at 2 hours, RDs (-14.2 and -3.6) again favored severe pain. In neither migraine nor ETTH does pre-treatment headache intensity predict success or failure of aspirin. This is not an arguable basis for stratified care in migraine. In both disorders, aspirin is first-line treatment regardless of headache intensity. © 2011 American Headache Society.

The purpose of this study was to assess the feasibility and utility of image fusion (Easy-TIPS) obtained from pre-procedure CT angiography and per-procedure real-time fluoroscopy for portal vein puncture during transjugular intrahepatic portosystemic shunt (TIPS) placement. Eighteen patients (15 men, 3 women) with a mean age of 63 years (range: 48-81 years; median age, 65 years) were included in the study. All patients underwent TIPS placement by two groups of radiologists (one group with radiologists of an experience<3 years and one with an experience≥3 years) using fusion imaging obtained from three-dimensional computed tomography angiography of the portal vein and real-time fluoroscopic images of the portal vein. Image fusion was used to guide the portal vein puncture during TIPS placement. At the end of the procedure, the interventional radiologists evaluated the utility of fusion imaging for portal vein puncture during TIPS placement. Mismatch between three-dimensional computed tomography angiography and real-time fluoroscopic images of the portal vein on image fusion was quantitatively analyzed. Posttreatment CT time, number of the puncture attempts, total radiation exposure and radiation from the retrograde portography were also recorded. Image fusion was considered useful for portal vein puncture in 13/18 TIPS procedures (72%). The mean posttreatment time to obtain fusion images was 16.4minutes. 3D volume rendered CT angiography images was strictly superimposed on direct portography in 10/18 procedures (56%). The mismatch mean value was 0.69cm in height and 0.28cm laterally. A mean number of 4.6 portal vein puncture attempts was made. Eight patients required less than three attempts. The mean radiation dose from retrograde portography was 421.2dGy.cm 2 , corresponding to a mean additional exposure of 19%. Fusion imaging resulting from image fusion from pre-procedural CT angiography is feasible, safe and makes portal puncture easier during TIPS placement

Hallucinogens and cannabinoids for headache.

PubMed

McGeeney, Brian E

2012-10-01

Most hallucinogens and cannabinoids fall into Federal Controlled Substances schedule 1, meaning they cannot be prescribed by practitioners, allegedly have no accepted medical use, and have a high abuse potential. The legal and regulatory status has inhibited clinical research on these substances such that there are no blinded studies from which to assess true efficacy. Despite such classification, hallucinogens and cannabinoids are used by patients with headache on occasion. Cannabinoids in particular have a long history of use for headache and migraine before prohibition and are still used by patients as a migraine abortive. Hallucinogens are being increasing used by cluster headache patients outside of physician recommendation mainly to abort a cluster period and to maintain quiescence for which there is considerable anecdotal success. © 2012 American Headache Society.

Two reports of flight-related headache.

PubMed

Nagatani, Kazuhiko

2013-07-01

Airplane headache is flight-related and appears during airplane landing and/or takeoff without accompanying symptoms. Intracranial and paranasal imaging studies reveal no abnormalities. The etiology is still uncertain, although sinus barotrauma has been proposed as a possible mechanism. 1) A 26-yr-old woman presented with recurring headache during each air travel since she was 22 yr old. Severe bursting pain suddenly manifested in the bilateral orbits and temples during airplane descent, with no accompanying additional symptoms. She had no unusual medical history. X-ray computed tomography (CT) scans showed no abnormalities except thickening of the nasal mucosa. Effective pain relief was obtained with over-the-counter nasal decongestant spray. 2) A 49-yr-old man presented with a 3-yr history of flight-related headache that appeared at airplane touchdown, when he had mental stress, or when he was suffering from a lack of sleep. Pain was of a severe jabbing quality, localized over the forehead with no additional accompanying symptoms. He had a past history of episodic tension-type headache. Intracranial and paranasal CT scan revealed no abnormalities. Headache ceased spontaneously within 40 min of the end of the flight and nonsteroidal anti-inflammatory drug premedication did not prevent the headache. Sinus barotrauma was thought to be a plausible explanation for the headache in Case 1. In Case 2, an anxiety disorder could be considered as an underlying etiology. The etiology of so-called airplane headache is probably protean and this should be taken into account when assessing cases of in-flight cephalalgia.

New daily persistent headache: An evolving entity.

2018-01-01

New daily persistent headache (NDPH) is characterized by an abrupt onset of headache that becomes a daily entity, is unremitting and continuous from the onset, and lasts for more than 3 months. Dr Walter Vanast first described NDPH in the year 1986. Originally, it was proposed as a chronic daily headache but it was placed under "other primary headaches" in the International Classification of Headache Disorder Second Edition (ICHD 2nd edition). However, with evolving literature and better understanding of its clinical characteristics, it was classified as a "chronic daily headache" in the ICHD 3 rd edition beta. There are still many knowledge-gaps regarding the underlying cause, pathophysiology, natural history and treatment of NDPH. This review tries to revisit the entity and discusses the current status of understanding regarding NDPH.

Strategies to prevent primary headaches could be very beneficial, especially given that primary headaches can lead to the development of chronic headache. In order to establish headache prevention strategies, the modifiable risk factors for primary headaches need to be identified. A systematic literature search on the risk factors for primary headaches was conducted independently by two persons using the databases MEDLINE and Embase. Further inclusion criteria were observational studies in adult general populations or case-control studies, where the effect sizes were reported as odds ratios or where the odds ratios could be calculated from the given data. In all, 24 studies were included in the analysis. There was a large amount of heterogeneity among the studies concerning headache acquisition, headache classification, and risk factors for headache development. Independent of headache trigger and definition of headache, the association between headache and the risk factor "stress" was very high: The meta-analysis shows an overall effect of 2.26 (odds ratio; 95 %-CI = [1.79; 2.85]). Studies evaluating neck and shoulder pain also report a strong association with headache; however, these results could not be summarized in a meta-analysis. Equally, the overall effects of smoking and coffee consumption on headaches could not be verified because the effect sizes were rather small and predominantly noticeable only at higher doses. A strong association between headache and the risk factors stress and neck and shoulder pain was confirmed. The effect sizes of smoking and coffee consumption on headaches were rather small.

OBJECTIVES. A training model was designed for learners and young physicians to polish their skills in clinical practices of pinpointing and puncturing trigeminal ganglion. METHODS. A head model, on both cheeks of which the deep soft tissue was replaced by stuffed organosilicone and sponge while the superficial soft tissue, skin and the trigeminal ganglion were made of organic silicon rubber for an appearance of real human being, was made from a dried skull specimen and epoxy resin. Two physicians who had experiences in puncturing foramen ovale and trigeminal ganglion were selected to test the model, mainly for its appearance, X-ray permeability, handling of the puncture, and closure of the puncture sites. Four inexperienced physicians were selected afterwards to be trained combining Hartel's anterior facial approach with the new method of real-time observation on foramen ovale studied by us. RESULTS. Both appearance and texture of the model were extremely close to those of a real human. The fact that the skin, superficial soft tissue, deep muscles of the cheeks, and the trigeminal ganglion made of organic silicon rubber all had great elasticity resulted in quick closure and sealing of the puncture sites. The head model made of epoxy resin had similar X-ray permeability to a human skull specimen under fluoroscopy. The soft tissue was made of radiolucent material so that the training can be conducted with X-ray guidance. After repeated training, all the four young physicians were able to smoothly and successfully accomplish the puncture. CONCLUSION. This self-made model can substitute for cadaver specimen in training learners and young physicians on foramen ovale and trigeminal ganglion puncture. It is very helpful for fast learning and mastering this interventional operation skill, and the puncture accuracy can be improved significantly with our new method of real-time observation on foramen ovale.

To assess the presence, prevalence and clinical characteristics of primary headaches in pediatric patients with chronic rheumatic diseases such as juvenile idiopathic arthritis (JIA) and familial Mediterranean fever (FMF), and to analyze the common pathophysiological mechanisms. In this noncontrolled, cross-sectional study, a semi-structured 53 item headache questionnaire was administered to subjects with FMF and JIA, and interviewed a total sample size of 601 patients younger than16years of age. The questionnaires were then analyzed according to the International Headache Society's diagnostic criteria. Children with FMF (n=378) and JIA (n=223) were studied. Each group was then divided into two subgroups according to whether the subjects reported headache or not. 29.5% of subjects with FMF reported having migraine, 37.6% probable migraine and 32.9% tension type headache (TTH). In JIA group 28.2% were diagnosed with migraine; 41.2% with probable migraine and 30.6% with TTH. No significant difference was found between all subjects with (n=258) and without (n=343) headache for variables such as living in a crowded family (p=0.95), being the first child in the family (p=0.63), academic achievement of the child (p=0.63), high education level (higher than high school) of the mother (p=0.52) and father (p=0.46). The presence of systemic disease was reported not to be effecting the daily life at the time of evaluation by 90.2% of the children with headache and 91.0% of the children without headache (p=0.94). 81.4% of the children reported their headaches were not aggravating with the exacerbation periods of their systemic disease. Family history of hypertension was reported higher by the subjects with headache (13.5% with headache and 4.0% without headache p=0.001). Diabetes mellitus was also reported higher (5.8% with headache; 0.5% without headache; p=0.006).

Cluster headache is characterized by severe, unilateral headache attacks of orbital, supraorbital or temporal pain lasting 15-180 min accompanied by ipsilateral lacrimation, rhinorrhea and other cranial autonomic manifestations. Cluster headache attacks need fast-acting abortive agents because the pain peaks very quickly; sumatriptan injection is the gold standard acute treatment. First-line preventative drugs include verapamil and carbolithium. Other drugs demonstrated effective in open trials include topiramate, valproic acid, gabapentin and others. Steroids are very effective; local injection in the occipital area is also effective but its prolonged use needs caution. Monoclonal antibodies against calcitonin gene-related peptide are under investigation as prophylactic agents in both episodic and chronic cluster headache. A number of neurostimulation procedures including occipital nerve stimulation, vagus nerve stimulation, sphenopalatine ganglion stimulation and the more invasive hypothalamic stimulation are employed in chronic intractable cluster headache.

To present results from the United States Cluster Headache Survey regarding gender differences in cluster headache demographics, clinical characteristics, diagnostic delay, triggers, treatment response and personal burden. Very few studies have looked at the gender differences in cluster headache presentation. The United States Cluster Headache Survey is the largest study of cluster headache sufferers ever completed in the United States and it is also the largest study of female cluster headache patients ever presented. The total survey consisted of 187 multiple choice questions which dealt with various issues related to cluster headache including: demographics, clinical characteristics, concomitant medical conditions, family history, triggers, smoking history, diagnosis, treatment response and personal burden. A group of questions were specifically targeted to female cluster headache patients. The survey was placed on a website from October to December 2008. For all survey responders the diagnosis of cluster headache needed to be made by a neurologist but there was no validation of the headache diagnosis by the authors. 1134 individuals completed the survey (816 male, 318 female). Key Points that define the differences between female and male cluster headache include: a. Age of onset: women develop cluster headache at an earlier age than men and are more likely to develop a second peak of cluster headache onset after 50 years of age. b. Family history: woman cluster headache sufferers are more likely to have a family history of both cluster headache and migraine and have an increased familial risk of Parkinson's disease. c. Comorbid conditions: female cluster headaches sufferers are significantly more likely to experience depression and have asthma than males. d. Aura issues: aura with cluster headache is equally common in both sexes, but aura duration is shorter in women. Women are much more likely to experience sensory, language and brainstem auras. e.

Construction of constant curvature punctured Riemann surfaces with particle-scattering interpretation

NASA Astrophysics Data System (ADS)

Bilal, Adel; Gervais, Jean-Loup

A class of punctured constant curvature Riemann surfaces, with boundary conditions similar to those of the Poincaré half plane, is constructed. It is shown to describe the scattering of particle-like objects in two Euclidian dimensions. The associated time delays and classical phase shifts are introduced and connected to the behaviour of the surfaces at their punctures. For each such surface, we conjecture that the time delays are partial derivatives of the phase shift. This type of relationship, already known to be correct in other scattering problems, leads to a general integrability condition concerning the behaviour of the metric in the neighbourhood of the punctures. The time delays are explicitly computed for three punctures, and the conjecture is verified. The result, reexpressed as a product of Riemann zeta-functions, exhibits an intringuing number-theoretic structure: a p-adic product formula holds and one of Ramanujan's identities applies. An ansatz is given for the corresponding exact quantum S-matrix. It is such that the integrability condition is replaced by a finite difference relation only involving the exact spectrum already derived, in the associated Liouville field theory, by Gervais and Neveu.

Vein punctures are performed daily to sample blood. Ultrasound (US) offers an alternative to the blind landmark technique for difficult vascular access. A challenge for this procedure is the presence of US gel in the puncture area. We present a technique for US-guided puncture from extremity veins not palpable or visible to the human eye, while keeping the puncture area dry and gel-free. Ten healthy volunteers underwent two US-guided vein punctures from veins that were neither palpable nor visible. One was drawn from an antebrachial vein and another from a brachial vein. A sterile barrier drape was made from a commercially available dressing and a piece of transparent sterile plastic. The barrier drape consists of an adhesive part placed on the skin designed for sonography and a free transparent flap constituting the barrier between the unsterile sonographic site and the sterile gel-free puncture site. The success rate for vein puncture was 100% in both locations. A total of 22 skin punctures were performed (11 antebrachial and 11 brachial). Gain output was increased 7% (4-12%), and 8% (4-15%), respectively, to compensate for attenuation of the US signal due to the drape. Alignment of the centre of the transducer with the long-axis of the target vein during the procedure was reported as a challenge. US-guided blood sampling from a brachial and antebrachial vein was possible with a 100% success rate, while ensuring a dry and gel-free venipuncture area on one side and the transducer on the other side of a sterile barrier.

PurposeTo prospectively compare the procedural time and complication rates of ultrasound-guided and fluoroscopy-assisted antegrade common femoral artery (CFA) puncture techniques.Materials and MethodsHundred consecutive patients, undergoing a vascular procedure for which an antegrade approach was deemed necessary/desirable, were randomly assigned to undergo either ultrasound-guided or fluoroscopy-assisted CFA puncture. Time taken from administration of local anaesthetic to vascular sheath insertion in the superficial femoral artery (SFA), patients’ age, body mass index (BMI), fluoroscopy radiation dose, haemostasis method and immediate complications were recorded. Mean and median values were calculated and statistically analysed with unpaired t tests.ResultsSixty-nine male and 31 female patients underwent antegrademore » puncture (mean age 66.7 years). The mean BMI was 25.7 for the ultrasound-guided (n = 53) and 25.3 for the fluoroscopy-assisted (n = 47) groups. The mean time taken for the ultrasound-guided puncture was 7 min 46 s and for the fluoroscopy-assisted technique was 9 min 41 s (p = 0.021). Mean fluoroscopy dose area product in the fluoroscopy group was 199 cGy cm{sup 2}. Complications included two groin haematomas in the ultrasound-guided group and two retroperitoneal haematomas and one direct SFA puncture in the fluoroscopy-assisted group.ConclusionUltrasound-guided technique is faster and safer for antegrade CFA puncture when compared to the fluoroscopic-assisted technique alone.« less

Four-dimensional computed tomography angiographic evaluation of cranial dural arteriovenous fistula before and after embolization.

This study aimed to evaluate the usefulness of four-dimensional CTA before and after embolization treatment with ONYX-18 in eleven patients with cranial dural arteriovenous fistulas, and to compare the results with those of the reference standard DSA. Eleven patients with cranial dural arteriovenous fistulas detected on DSA underwent transarterial embolization with ONYX-18. Four-dimensional CTA was performed an average of 2 days before and 4 days after DSA. Four-dimensional CTA and DSA images were reviewed by two neuroradiologists for identification of feeding arteries and drainage veins and for determining treatment effects. Interobserver and intermodality agreement between four-dimensional CTA and DSA were assessed. Forty-two feeding arteries were identified for 14 fistulas in the 11 patients. Of these, 36 (85.71%) were detected on four-dimensional CTA. After transarterial embolization, one patient got partly embolized, and the fistulas in the remaining 10 patients were completely occluded. The interobserver agreement for four-dimensional CTA and intermodality agreement between four-dimensional CTA and DSA were excellent (κ=1) for shunt location, identification of drainage veins, and fistula occlusion after treatment. Four-dimensional CTA images are highly accurate when compared with DSA images both before and after transarterial embolization treatment. Four-dimensional CTA can be used for diagnosis as well as follow-up of cranial dural arteriovenous fistulas in clinical settings. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Headache (chronic tension-type)

2009-01-01

Introduction Chronic tension-type headache (CTTH) is a disorder that evolves from episodic tension-type headache, with daily or very frequent episodes of headache lasting minutes to days. It affects 4.1% of the general population in the USA, and is more prevalent in women (up to 65% of cases). Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of drug treatments for chronic tension-type headache? What are the effects of non-drug treatments for chronic tension-type headache? We searched: Medline, Embase, The Cochrane Library, and other important databases up to March 2007 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 50 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review, we present information relating to the effectiveness and safety of the following interventions: acupuncture; amitriptyline; analgesics; anticonvulsant drugs; benzodiazepines; botulinum toxin; chiropractic and osteopathic manipulations; cognitive behavioural therapy (CBT); Indian head massage; mirtazapine; relaxation and electromyographic biofeedback; selective serotonin reuptake inhibitor antidepressants (SSRIs); and tricyclic antidepressants (other than amitriptyline).

Posttraumatic Headache: Basic Mechanisms and Therapeutic Targets.

Kamins, Joshua; Charles, Andrew

2018-06-01

Frequent or continuous headache, often refractory to medical therapy, is a common occurrence after head trauma. In addition to being the most common acute symptom after traumatic brain injury (TBI), headache is also one of the most persistent and disabling symptoms. Different studies indicate that 18-58% of those suffering a TBI will have significant headache at 1 year following the trauma. In addition to being disabling on its own, posttraumatic headache (PTH) is a predictor of overall outcome after concussion. Despite its remarkable prevalence and associated social and economic costs, many fundamental and important questions about PTH remain unanswered. The purpose of this review is to identify key questions regarding the clinical characteristics of posttraumatic headache, its basic mechanisms, and its optimal management. We discuss phenotypic features of PTH, pathophysiological mechanisms of TBI including potential overlaps with those of migraine and other primary headache disorders, and potential novel targets for treatment. We suggest different strategies to finding answers to the questions regarding PTH in order to advance the understanding of the disorder and develop more effective therapies. © 2018 American Headache Society.

This study reports on the latest advances in childhood headaches that have been made in the last few years, with special emphasis on the important new modifications that have been produced with respect to the previous ones, published in the beta version of the third edition of the International Classification of Headache Disorders. These include headaches that have undergone important qualifications, the appearance of new entities and a section which reports the existence of new headaches, but which have still not been considered as new entities. Additionally, other points that are highlighted include the strong relation between childhood headaches and attention deficit hyperactivity disorder, the weak relation between glutamate intake and the appearance of headaches, and the scant usefulness of magnetic resonance imaging of the brain in the diagnosis of these processes. Moreover, the new modification produced in childhood episodic syndromes is highlighted.

Abstract Headache disorders are common, debilitating, and, in many cases, inadequately managed by existing treatments. Although clinical trials of cannabis for neuropathic pain have shown promising results, there has been limited research on its use, specifically for headache disorders. This review considers historical prescription practices, summarizes the existing reports on the use of cannabis for headache, and examines the preclinical literature exploring the role of exogenous and endogenous cannabinoids to alter headache pathophysiology. Currently, there is not enough evidence from well-designed clinical trials to support the use of cannabis for headache, but there are sufficient anecdotal and preliminary results, as well as plausible neurobiological mechanisms, to warrant properly designed clinical trials. Such trials are needed to determine short- and long-term efficacy for specific headache types, compatibility with existing treatments, optimal administration practices, as well as potential risks.

The aim of the report is to present a case of an autonomic headache associated with autonomic seizures. A 19-year-old male who had had complex partial seizures for 15 years was admitted with autonomic complaints and left hemicranial headache, independent from seizures, that he had had for 2 years and were provoked by watching television. Brain magnetic resonance imaging showed right hippocampal sclerosis and electroencephalography revealed epileptic activity in right hemispheric areas. Treatment with valproic acid decreased the complaints. The headache did not fulfil the criteria for the diagnosis of trigeminal autonomic cephalalgias, and was different from epileptic headache, which was defined as a pressing type pain felt over the forehead for several minutes to a few hours. Although epileptic headache responds to anti-epileptics and the complaints of the present case decreased with antiepileptics, it has been suggested that the headache could be a non-trigeminal autonomic headache instead of an epileptic headache.

Recurrent headache is a common problem in school children. Evaluation generally leads to the diagnosis of a primary headache syndrome (migraine or tension-type headache). This review is addressed to the question whether headaches in school children are becoming more common and, if so, what risk factors are associated with the rise in frequency. We selectively searched the PubMed database for pertinent publications that contained the terms "primary headache AND children/adolescent AND risk factors/prevalence." Articles published in either English or German up to April 2013 were considered. Articles on secondary types of headache were excluded. Headaches are becoming more common among school children. At present, 66% to 71% of 12- to 15- year-olds have at least one headache every three months, and 33% to 40% have at least one per week. Headache is often accompanied by other physical and/or emotional manifestations. Studies from Scandinavia reveal increasing prevalence in age groups from 8 years of age and upward. Various studies have identified the following risk factors for headache or for its chronification (up to 5.8-fold elevation of risk): a dysfunctional family situation, the regular consumption of alcohol, caffeine ingestion, smoking, a low level of physical activity, physical or emotional abuse, bullying by peers, unfair treatment in school, and insufficient leisure time. Headaches are becoming more common among children and adolescents. They are often associated with other physical and emotional complaints.

The goal of this study was to determine the vascular effects of protease-activated receptor-2 (PAR-2) activation in the rat cranial vasculature. The role of PAR-2 in pain and inflammatory conditions has been established but the information available on its effects and receptor distribution in the trigeminal vascular axis is limited. We studied the dilatory function and expression of PAR-2 in the neuro-vascular circuit, critical in migraine pathogenesis. We also investigated the interaction of PAR-2 with calcitonin gene-related peptide (CGRP) and dural mast cells. We used an improved model of intravital microscopy on the closed cranial window in rats to study the vascular effects of PAR-2 activating peptides (PAR-2 APs; SLIGRL-NH(2), 2-Furoyl-LIGRLO-NH(2)) in the dural vasculature. Measurement of immunoreactive CGRP in skull halves and in trigeminal nucleus caudalis was done by using an enzyme-linked immunosorbent assay. We also analyzed the presence of PAR-2 in different migraine relevant tissues by quantitative real-time PCR and Western blot analysis. PAR-2 APs and trypsin induced a dose-dependent increase in dural artery diameter. The topical application of a nonspecific nitric oxide synthase (NOS) inhibitor, L-N(G)-Nitroarginine methyl ester, attenuated SLIGRL-NH(2) responses. Olcegepant, a CGRP receptor antagonist, did not a have significant effect on the SLIGRL-NH(2) responses, though exogenous CGRP responses were completely blocked. There was no significant release of CGRP from skull halves incubated with SLIGRL-NH(2) as compared with those incubated with the corresponding negative peptide. Chronic mast cell degranulation did not change the vascular effects of PAR-2 APs. mRNA and protein expression of PAR-2 were found throughout trigeminovasuclar axis. PAR-2 activation leads to vasodilation of dural arteries and these responses are partially mediated by nitric oxide. As PAR-2 is present throughout trigeminovasuclar axis, it may have a role in migraine

Unlike the prevalence, the incidence of headache disorders has attracted only little attention in epidemiological research. Different definitions of the 'population at risk' among the few published migraine and tension-type headache incidence studies limit their comparability and warrant further research. Therefore, we analysed data from the German Migraine and Headache Society (DMKG). Incidences were assessed in the general population in Germany via standardized headache questions using the International Classification of Headache Disorders, 2nd Edition (ICHD-2). The population was drawn from a 5-year age-group- stratified and gender-stratified random sample from the population register. Of the 1312 baseline participants examined between 2003 and 2004, 1122 (85.5%) participated in the follow-up in 2006 and were the basis for three different populations at risk. We found that the three populations differed in size, age, gender and incidence estimate. The total sample incidence of migraine ranged between 0% and 3.3% and of tension-type headache between 5.3% and 9.2% depending on the definition of 'at risk'. We concluded that one significant problem in headache incidence estimation is the definition of 'at risk', limiting comparability. Thus, this study supports the need for a common definition for prospective headache incidence estimations.

Background The blood-brain barrier (BBB) has been hypothesized to play a role in migraine since the late 1970s. Despite this, limited investigation of the BBB in migraine has been conducted. We used the inflammatory soup rat model of trigeminal allodynia, which closely mimics chronic migraine, to determine the impact of repeated dural inflammatory stimulation on BBB permeability. Methods The sodium fluorescein BBB permeability assay was used in multiple brain regions (trigeminal nucleus caudalis (TNC), periaqueductal grey, frontal cortex, sub-cortex, and cortex directly below the area of dural activation) during the episodic and chronic stages of repeated inflammatory dural stimulation. Glial activation was assessed in the TNC via GFAP and OX42 immunoreactivity. Minocycline was tested for its ability to prevent BBB disruption and trigeminal sensitivity. Results No astrocyte or microglial activation was found during the episodic stage, but BBB permeability and trigeminal sensitivity were increased. Astrocyte and microglial activation, BBB permeability, and trigeminal sensitivity were increased during the chronic stage. These changes were only found in the TNC. Minocycline treatment prevented BBB permeability modulation and trigeminal sensitivity during the episodic and chronic stages. Discussion Modulation of BBB permeability occurs centrally within the TNC following repeated dural inflammatory stimulation and may play a role in migraine. PMID:28457145

The methodology of population surveys of headache prevalence, burden and cost: Principles and recommendations from the Global Campaign against Headache

PubMed Central

2014-01-01

The global burden of headache is very large, but knowledge of it is far from complete and needs still to be gathered. Published population-based studies have used variable methodology, which has influenced findings and made comparisons difficult. Among the initiatives of the Global Campaign against Headache to improve and standardize methods in use for cross-sectional studies, the most important is the production of consensus-based methodological guidelines. This report describes the development of detailed principles and recommendations. For this purpose we brought together an expert consensus group to include experience and competence in headache epidemiology and/or epidemiology in general and drawn from all six WHO world regions. The recommendations presented are for anyone, of whatever background, with interests in designing, performing, understanding or assessing studies that measure or describe the burden of headache in populations. While aimed principally at researchers whose main interests are in the field of headache, they should also be useful, at least in parts, to those who are expert in public health or epidemiology and wish to extend their interest into the field of headache disorders. Most of all, these recommendations seek to encourage collaborations between specialists in headache disorders and epidemiologists. The focus is on migraine, tension-type headache and medication-overuse headache, but they are not intended to be exclusive to these. The burdens arising from secondary headaches are, in the majority of cases, more correctly attributed to the underlying disorders. Nevertheless, the principles outlined here are relevant for epidemiological studies on secondary headaches, provided that adequate definitions can be not only given but also applied in questionnaires or other survey instruments.

A review of the latest and most relevant information on different disorders of head and facial pain is presented. News from epidemiologic studies regarding the relationship between migraine and patent foramen ovale, the cardiovascular risk in migraine, and migraine behavior during menopause, and the development of white matter lesions or migraine genetics are presented. Regarding pathophysiology there are very recent insights regarding the role of the hypothalamus during prodromal phase and the interplay of brain-stem and hypothalamus during the attack. In the last year studies and metaanalysis generated new knowledge for the use of triptans in general as in menstrual related migraine and hemiplegic variants. Furthermore, new hope rises for the CGRP (calcitonin-gene related peptide)-antagonists, as the data for ubrogepant do not suggest hepatotoxicity but efficacy. In prophylactic migraine treatment the news are manly on how the new therapeutic approach with monoclonal antibodies against CGRP or its receptor is moving on. Additional newly generated data for already known prophylactic agents as for new approaches are compactly discussed. Although main developments in headache focus on migraine new data on trigemino-autonomic headache trigeminal neuralgia and new daily persistant headache became available.

ObjectiveTo assess the feasibility of a hybrid approach employing MRI-guided bile duct (BD) puncture for subsequent fluoroscopy-guided biliary interventions in patients with non-dilated (≤3 mm) or dilated BD (≥3 mm) but unfavorable conditions for ultrasonography (US)-guided BD puncture.MethodsA total of 23 hybrid interventions were performed in 21 patients. Visualization of BD and puncture needles (PN) in the interventional MR images was rated on a 5-point Likert scale by two radiologists. Technical success, planning time, BD puncture time and positioning adjustments of the PN as well as technical success of the biliary intervention and complication rate were recorded.ResultsVisualization even of third-order non-dilated BDmore » and PN was rated excellent by both radiologists with good to excellent interrater agreement. MRI-guided BD puncture was successful in all cases. Planning and BD puncture times were 1:36 ± 2.13 (0:16–11:07) min. and 3:58 ± 2:35 (1:11–9:32) min. Positioning adjustments of the PN was necessary in two patients. Repeated capsular puncture was not necessary in any case. All biliary interventions were completed successfully without major complications.ConclusionA hybrid approach which employs MRI-guided BD puncture for subsequent fluoroscopy-guided biliary intervention is feasible in clinical routine and yields high technical success in patients with non-dilated BD and/or unfavorable conditions for US-guided puncture. Excellent visualization of BD and PN in near-real-time interventional MRI allows successful cannulation of the BD.« less

Primary stabbing headache.

PubMed

Pareja, Juan A; Sjaastad, Ottar

2010-01-01

Primary stabbing headache is characterized by transient, cephalic ultrashort stabs of pain. It is a frequent complaint with a prevalence of 35.2%, a female preponderance, and a mean age of onset of 28 years (Vågå study). Attacks are generally characterized by moderate to severe, jabbing or stabbing pain, lasting from a fraction of a second to 3s. Attack frequency is generally low, with one or a few attacks per day. The paroxysms generally occur spontaneously, during daytime. Most patients exhibit a sporadic pattern, with an erratic, unpredictable alternation between symptomatic and non-symptomatic periods. Paroxysms are almost invariably unilateral. Temporal and fronto-ocular areas are most frequently affected. Attacks tend to move from one area to another, in either the same or the opposite hemicranium. Jabs may be accompanied by a shock-like feeling and even by head movement - "jolts" -or vocalization. On rare occasions, conjunctival hemorrhage and monocular vision loss have been described as associated features. Primary stabbing headache may concur, synchronously or independently, with other primary headaches. In contrast to what is the case in adults, in childhood it is not usually associated with other headaches. Treatment is rarely necessary. Indomethacin, 75-150 mg daily, may seem to be of some avail. Celecoxib, nifedipine, melatonin, and gabapentin have been reported to be effective in isolated cases and small series of patients. The drug studies need corroboration. Copyright © 2011 Elsevier B.V.

There is abundance of epidemiological studies of headache in developed and western countries; however, data in developing countries and in Egypt are still lacking. This study aims to detect the prevalence of primary headache disorders in both urban and rural sectors in Fayoum governorate, Egypt. A total of 2600 subjects were included using multi-stage stratified systematic random sampling, with respondent rate of 91.3 %. A pre-designed Arabic version, interviewer-administered, pilot tested structured questionnaire was developed according to The International Classification of Headache Disorders, 3rd edition (beta version), and this questionnaire was validated and the strength of agreement in headache diagnosis was good. The 1-year headache prevalence was 51.4 %, which was more prevalent in urban dwellers. The most common primary headache type was episodic tension type headache (prevalence; 24.5 %), followed by episodic migraine (prevalence; 17.3 %), both types peaked in midlife. Headache disorders were more common in females with exception of cluster headache that showed the expected male dominance. The risk of chronic headache increased more than one fold and half when the participants were females, married, and in those with high education. More than 60 % of our participants did not seek medical advice for their headaches problem; this percentage was higher in rural areas. Primary headache disorders are common in Egypt; prevalence rate was comparable with western countries with exception of episodic tension headache. Still headache is under-estimated and under-recognized in Egypt and this problem should be targeted by health care providers.

To examine symptoms indicating central nervous system (CNS) autonomic dysfunction in pediatric patients with migraine and tension-type headache. A retrospective chart review assessed six symptoms (i.e. constipation, insomnia, dizziness, blurry vision, abnormal blood pressure, and cold and clammy palms and soles) indicating central nervous system (CNS) autonomic dysfunction in 231 patients, ages 5-18 years, diagnosed with migraine, tension-type headache (TTH), or Idiopathic Scoliosis (IS). Higher frequencies of "insomnia," "dizziness," and "cold and clammy palms and soles" were found for both migraine and TTH patients compared to the IS control group (P < 0.001). Frequencies of all six symptoms were greater in TTH than migraine patients with "cold and clammy palms and soles" reaching significance (P < 0.001). The need for prospective research investigating autonomic dysfunction in pediatric headache patients is discussed.

This study examined somatic, psychological, and cognitive functioning of subjects with posttraumatic headache in comparison with multiple control groups. Posttraumatic headache is not as widely studied as other forms of headache (eg, tension-type, migraine). Previous research has suggested poor psychological functioning in patients with posttraumatic headache in comparison with other groups of patients with pain; however, this group has yet to be compared with a group of persons who have experienced trauma but are headache-free. Nineteen subjects with posttraumatic headache were studied, with full assessments available for 14 participants. Comparison groups, containing 16 participants each, included another headache group, a nonheadache group, and a trauma (motor vehicle accident) survivor nonheadache group. Participants completed several measures assessing somatic, psychological, and cognitive functioning. Findings revealed that the posttraumatic headache group exhibited significantly poorer functioning than the comparison groups on several measures including the Psychosomatic Symptom Checklist, Postconcussion Syndrome Checklist, axis II psychiatric diagnoses, Minnesota Multiphasic Personality Inventory, and the Daily Hassles Scale (frequency and total). Additionally, they scored higher on the following: number of axis I psychiatric diagnoses, the Daily Hassles Scale (intensity), Beck Depression Inventory, State-Trait Anxiety Inventory, and State-Trait Anger Expression Inventory. The posttraumatic headache group was similar to the other trauma group on the Posttraumatic Stress Disorder Symptom Checklist and the Life-Trauma Checklist. This study confirmed the distress seen in this understudied population of persons with headache and highlights areas of focus for proper assessment and treatment of those with headache and who have had an accident.

The objective of this paper was to assess prevalence and characteristics of anxiety and depression in migraine without aura and tension-type headache, either isolated or in combination. Although the association between headache and psychiatric disorders is undisputed, patients with migraine and/or tension-type headache have been frequently investigated in different settings and using different tests, which prevents meaningful comparisons. Psychiatric comorbidity was tested through structured interview and the MINI inventory in 158 adults with migraine without aura and in 216 persons with tension-type headache or migraine plus tension-type headache. 49 patients reported psychiatric disorders: migraine 10.9%, tension-type headache 12.8%, and migraine plus tension-type headache 21.4%. The MINI detected a depressive episode in 59.9, 67.0, and 69.6% of cases. Values were 18.4, 19.3, and 18.4% for anxiety, 12.7, 5.5, and 14.2%, for panic disorder and 2.3, 1.1 and 9.4% (p = 0.009) for obsessive-compulsive disorder. Multivariate analysis showed panic disorder prevailing in migraine compared with the other groups (OR 2.9; 95% CI 1.2-7.0). The association was higher (OR 6.3; 95% CI 1.4-28.5) when migraine (with or without tension-type headache) was compared to pure tension-type headache. This also applied to obsessive-compulsive disorder (OR 4.8; 95% CI 1.1-20.9) in migraine plus tension-type headache. Psychopathology of primary headache can reflect shared risk factors, pathophysiologic mechanisms, and disease burden.

The ability to accurately determine the number of syringe needle penetration holes through the rubber stoppers in pharmaceutical vials and rubber septa in intravenous (i.v.) line and bag ports has been a critical factor in a number of forensic cases involving the thefts of controlled substances or suspected homicide by lethal injection. In the early 1990s, the microscopy and microanalysis group of the U.S. Food and Drug Administration's Forensic Chemistry Center (FCC) developed and implemented a method (unpublished) to locate needle punctures in rubber pharmaceutical vial stoppers. In 1996, as part of a multiple homicide investigation, the Indiana State Police Laboratory (ISPL) contacted the FCC for information on a method to identify and count syringe needle punctures through rubber stoppers in pharmaceutical vials. In a joint project and investigation using the FCC's needle hole location method and applying a method of puncture site mapping developed by the ISPL, a systematic method was developed to locate, identify, count, and map syringe punctures in rubber bottle stoppers or i.v. bag ports using microscopic analysis. The method requires documentation of punctures on both sides of the rubber stoppers and microscopic analysis of each suspect puncture site. The final result of an analysis using the method is a detailed diagram of puncture holes on both sides of a questioned stopper and a record of the minimum number of puncture holes through a stopper.
