2010) asymmetric grooming, the rats display an uninterrupted series of at least three wash strokes directed to the stimulated area. The score was assumed to reflect the magnitude of the aversiveness

evoked by the mechanical stimulation, being equal to zero in the case of absence of response. A mean score value was then calculated for each stimulation series. Immunohistochemical analysis The rats were deeply anesthetized with urethane (1.5 g/kg i.p.). Twenty minutes after the induction of anesthesia, rats were stimulated for 2 min on one infraorbital region by gentle air puffing (60 stimuli delivered, 0.5 Hz). Three minutes after the end of stimulation, the rats were perfused transcardially with warm (37°C) heparinized saline (25 Inhibitors,research,lifescience,medical IU heparin/mL) followed Inhibitors,research,lifescience,medical by cold (10°C) phosphate-buffered solution (0.1 mol/L, pH 7.6) containing 4% paraformaldehyde and 0.03% picric acid for 15 min. The brainstem was then removed and transferred to the same fixative solution for 1 h and then placed in 30% sucrose and 0.05% sodium azide solution overnight at 4°C. Coronal 40-μm thick sections of the brainstem

were cut on a freezing microtome (Leica, Wetzlar, Germany) and collected in a 0.05 mol/L Tris-buffered saline (TBS). For immunofluorescence, free-floating Inhibitors,research,lifescience,medical brainstem sections were placed in 1% normal goat serum for 1 h before overnight incubation at room temperature in primary antibody solutions (mouse and rabbit antiphosphorylated extracellular signal-regulated kinases 1/2 [pERK1/2] [1:1000, Cell Signaling Technologies, Danvers, MA], and mouse and rabbit anti-PKCγ [1:4000, Sigma-Aldrich and Santa Cruz, Dallas, TX]). The corresponding secondary antibodies (1:400 for goat anti-mouse Cy3, 1:200 for goat anti-rabbit Cy2) were incubated Inhibitors,research,lifescience,medical at room temperature for 3 h. All antibodies were diluted in TBS containing 0.25% bovine serum albumin and 0.3% Triton X-100. The sections were finally rinsed in TBS, mounted on gelatin-coated slides, dehydrated in alcohol, scientific study cleared in xylene, and coverslipped Inhibitors,research,lifescience,medical with 1,3-diethyl-8-phenylxanthine (DPX) medium. The specificity of the immunostaining was assessed

by omitting the primary antibodies, which resulted in the absence of signal. Immunofluorescent staining was analyzed by using a motorized Brefeldin_A Zeiss R115777 Axioplan 2 microscope equipped with a Hamamatsu C4742-95 digital camera (Hamamatsu Photonics France SARL, Massy, France) (switching between FITC and Texas Red filter sets) driven by MetaMorph® 5.4 software. In each rat, image acquisition and fluorescent signal quantification were done using seven different sections, each taken at a given rostrocaudal plane within the MDH (from 0 to −2160 μm at 360 μm intervals). To reduce the variability in staining between sections, the same area of the MDH was taken in consideration for quantification of the fluorescent signal. Measurement of PKCγ fluorescence was taken from the layer IIi as it contained the majority of interneurons positive for this marker.

2009] and it has been http://www.selleckchem.com/products/Pazopanib-Hydrochloride.html further proposed that, given the likelihood of this shared neural circuitry, there is potential value in the assessment of motor signs when screening for psychosis risk [Mittal et

al. 2008]. The investigation of motor abnormalities in patients with mental illness has historically relied on rating scales. A more complex objective measure has been employed by neurologists investigating nonverbal communication [Altorfer Inhibitors,research,lifescience,medical et al. 2008]. They employed a motion-capture technique using video of a subject in general conversation with an interviewer. Subsequent analysis demonstrated a reduction in the frequency and amplitude of a subject’s head movements during speech in patients versus controls, significant

at the level of the individual regardless of whether subjects were taking antipsychotics or drug-naïve. Their technique required specialized equipment in a specialized environment in order to make these assessments. Schizophrenia has been implicated in many aspects of communication Inhibitors,research,lifescience,medical and the neuronal circuitry involved. Abnormalities in head movements, including those during speech, may shed light upon abnormalities at both behavioral and neuronal levels, including Inhibitors,research,lifescience,medical the abnormalities in the basal ganglia that lead to conditions such as tardive dyskinesia. Objective measurement of these movements could be more sensitive than existing scales used to rate abnormal movements. We sought to capture and compare head movements during conversation, in patients with schizophrenia and controls, using a commercially available movement sensor in a variety of clinical settings. Methods and materials Ethical approval was obtained from the local research ethics committee, Nottingham Research Ethics Committee Inhibitors,research,lifescience,medical 1 (NHS National Research Ethics Service). Informed selleck compound consent was obtained from a referred sample of patients with capacity, assessed by an

experienced senior clinician (BDM). Clinical case note ICD-10 diagnoses were made by a consensus of three senior clinicians. Data was initially analyzed from the first 6 cases and controls; a power Inhibitors,research,lifescience,medical calculation at this stage suggested that 11 cases and 11 controls would be sufficient to demonstrate an effect at the level of the individual with p < 0.05. A total of 11 patients with an ICD-10 diagnosis of paranoid schizophrenia and 11 healthy controls were recruited to the study. Equipment A commercially available movement sensor the size of a matchbox was obtained (Insight SENS Drug_discovery Advanced IMU 110: Insight Sports, http://www.insight-sports.com). This is a self-powered unit measuring rotation and linear displacement in three axes using accelerometers and magnetometers. It was mounted on the peak of a baseball cap, such that the sensor was not in the wearer’s visual field, and was linked via Bluetooth to a laptop computer that recorded the data in real time. Simultaneous audio recording was employed to allow identification of who was speaking.

The fusimotor system controls joint muscles for tension, balance,

The fusimotor system controls joint muscles for tension, balance, and coordination of the joint movements (feedback regulation) (Roll et al. 1989). Like any other skeletal muscle, middle ear muscles (i.e., tensor tympani and stapedius)

possess muscle spindles (five on average) as well as a fusimotor system (one to three intrafusal fibers) (Kierner et al. 1999). Conceivably, high acoustic pressures of firearms could cause, besides hearing loss, stretch/contraction Inhibitors,research,lifescience,medical microlesions on muscles and joint tendons of the middle ear due to exaggerated acoustic reflexes, with resulting deleterious effects on fusimotor system of middle ear muscle spindles, and proprioception dysfunction. Action Inhibitors,research,lifescience,medical of middle ear muscles was required for the auditory task in the MRI noisy environment. Movement preparation or achievement probably triggers widespread muscle tone response, which may account for a sensitizing effect of the motor activity involved in “target” conditions, in revealing middle ear proprioceptive anomalies in AAT patients. The emotional and sensorimotor anomalies associated with AAT may

be aggravating co-factors, ultimately generating abnormal physical constraints along the tympano-ossicular chain calcitriol?hormone through, for instance, tension in the temporo-mandibular region (Allin 1975; Al–Ani and Gray 2007). Additionally, anxiety and stress activate the sympathetic system that Inhibitors,research,lifescience,medical innervates the muscle spindles (Nozzoli et al. 1987). The relative importance of mechanical dysregulation or of emotional hyperreactivity Inhibitors,research,lifescience,medical in middle ear proprioceptive dysfunction is a matter

of conjecture and may vary from subject to subject. In general, proprioceptive dysfunction causes mild confusion and a reduction of the accuracy of task performance (Verschueren et al. 1999) that may also explain the differences in performance observed between AAT and control groups during the behavioral task. Inhibitors,research,lifescience,medical Our results led us to envisage besides an emotional disturbance, the possibility of a relationship between middle ear proprioceptive dysfunction and tinnitus in AAT subjects. Mechanistic origin of tinnitus The mechanistic origin of tinnitus is still a matter of debate. Cochlear cell damage (Liberman and Dodds 1987) is widely considered as a most likely origin for AAT tinnitus. It is widely assumed that cochlear Batimastat cell damage triggers changes in the central auditory system, which is then interpreted as tinnitus by the higher processing stages in the brain (Jastreboff 1990; Roberts et al. 2010). Thus, hyperactivity and synchronization of neural firing in the dorsal cochlear nucleus, inferior colliculus or the auditory cortex in acoustic traumas has been selleck products reported (Rajan and Irvine 1998; Kaltenbach 2000; Eggermont 2003, 2006; Norena and Eggermont 2003) and attributed to an imbalance of exitability between the cochlear inner hair cells (IHC) and the outer hair cells (OHC) (Jastreboff 1990; Shiomi et al. 1997; Job et al. 2007).

Likewise, a code based on the exact number of spikes elicited by

Likewise, a code based on the exact number of spikes elicited by each neuron might be irrelevant in the face of similar fluctuations in response amplitude. In two recent studies,38,39 we have examined the range

of truly possible representation schemes and their feasibility in view of the intense fluctuation in the responses. We have initially shown that in spontaneously developing large-scale random networks of cortical Sorafenib B-Raf neurons in vitro the order in which neurons are recruited following each stimulus is a naturally emerging representation primitive that is invariant to significant temporal changes in spike times. With a relatively small number Inhibitors,research,lifescience,medical of randomly sampled neurons, the information about stimulus position is fully retrievable from the recruitment order. It seems that this is due to the existence Inhibitors,research,lifescience,medical of propagation paths: chains of neuronal stations through which activity is required to pass in order to propagate further into the network, regardless of the status

of membrane and synaptic dynamics, Inhibitors,research,lifescience,medical as can be seen in Figure 4. Figure 4 Demonstration of neuronal stations through which activity is required to pass in order to propagate further into the network. A: Pair-order probability matrices, generated from responses to three different stimulation sources of one network: The matrices … In a second study, we followed the path of a stimulus reconstruction approach to compare systematically the representational efficacy of four types Inhibitors,research,lifescience,medical of popular schemes, two rate-based and two time-based: population-count histogram, spike-count, time-to-first-spike, and rank-order. We found that the nature of response in neural populations

dictates strong correlations Inhibitors,research,lifescience,medical between different response features, which are a priori independent (e.g. rank order of first events and population time histogram are completely orthogonal features of a set of general spike trains38,40), resulting in high redundancy in response features. Thus, all representation schemes perform relatively well under all conditions, with an advantage to either scheme depending on the stimulus properties. Time-based representation schemes are also more stable over long periods of time, under changes induced by the long-term dynamics of the neural assembly. Carfilzomib On the other hand, when classification between temporal features of a given stimulus source is sought, there is an advantage to rate-based representation schemes, which are more sensitive to adaptation processes, and hence contain information with regard to the history of stimulation. We have also found that overlap between groups of receptive sheath neurons (neurons that directly respond to the stimulus and serve as a source for the assembly excitation) is translated to similarity in response pattern and can be thought of as a form of generalization.

The Scandinavian

The Scandinavian

study reported a 40% reduction in prostate cancer mortality attributable to PSA screening, which is consistent with the declining prostate cancer mortality statistics seen in the United States.36 Despite the compelling prostate cancer survival advantage of prostate cancer screening, the US Preventative Task Force (USPTF) made a general recommendation against PSA screening because they interpreted the literature to show that PSA screening produced more harm than benefit.42 The debate regarding the value of PSA screening played Inhibitors,research,lifescience,medical out in the lay press for several weeks. How the primary care physician will react to the controversy regarding PSA screening is unclear. There Inhibitors,research,lifescience,medical is also uncertainty as to whether the Center for Medicare LY188011 Services (CMS) will continue to reimburse for PSA screening; if the USPTF recommends against PSA screening, then CMS may decide to cease PSA reimbursement. The ultimate decision regarding coverage for PSA screening will certainly influence the proportion of men who will be screened in the future. Inhibitors,research,lifescience,medical A randomized study comparing radical prostatectomy (RP) versus watchful waiting for localized disease diagnosed in the pre-PSA screening era reported that 40% of the men undergoing RP received ADT.43 There is no doubt that prostate screening decreases

prostate cancer mortality, but this occurs at the expense of subjecting many men with low-risk Inhibitors,research,lifescience,medical disease to unnecessary treatment. Rather than summarily abandoning prostate cancer screening, there is a need to rationally risk stratify newly diagnosed cancers in order to maintain the reduction in prostate cancer mortality while limiting unnecessary treatment. There has been a decline in the use of ADT for prostate cancer due

in part to fewer men developing metastatic Inhibitors,research,lifescience,medical disease as the result of screening and subsequent curative localized therapies. There has also been a higher threshold for selleck compound administering these treatments due to increased awareness of potentially significant adverse events. If the diagnostic milieu is turned back to the pre-screening era, this may ironically, and unfortunately, result in more ADT utilization. More men will once again present with locally advanced or metastatic disease that is no longer amenable to localized cure and will be more appropriately managed with ADT. Adverse Effects of ADT T suppression is associated with Carfilzomib bone loss,44 which may also be influenced by other factors such as obesity, age, and sedentary lifestyle. Moreover, ADT and attendant bone demineralization is associated with an increased risk of skeletal fracture.45 Skeletal fractures are of particular concern, given their documented correlation with decreased overall survival in men with prostate cancer.46 ADT has also been correlated with several metabolic complications.

3). Figure 3 Bar chart illustrating left and right hippocampal volumes computed from MRI for intact hippocampi, AD without HS, bilateral HS, left-only HS, and right-only HS. Analysis of variance showed significant group differences in hippocampal MRI volumes (P < 0.001). Post hoc comparisons showed 32% greater atrophy in bilateral HS compared with AD (P < 0.001). There were also statistically significant differences Inhibitors,research,lifescience,medical between intact versus AD and intact versus HS for both right and left hippocampi

(P < 0.001). On average, volumes for HS hippocampus were 52% and AD volumes were 30% less than intact hippocampi. As one might expect, for left-only HS, the left HV was smaller than the right (P = 0.002), and for right-only HS, the right volume was smaller than the left (P = 0.04). Inhibitors,research,lifescience,medical As noted previously in the literature (Wang et al. 2003; Lye et al. 2004), in the cases with intact hippocampi, the right hippocampus was significantly larger than the left hippocampus (P = 0.009). The right HV for right-only HS was 31.3% larger than the left HV for left-only

Inhibitors,research,lifescience,medical HS (P = 0.01), which may reflect Regorafenib chemical structure underlying hemispheric asymmetries found in selleck chemical KPT-330 normal controls. Of interest, in right- or left-only HS cases, the MRI volumes in the contralateral and apparently uninvolved hippocampus were smaller than normal. For left-only HS cases, the right HV was significantly less than for normal controls (P = 0.0002). For right-only HS cases, there was a trend showing smaller volume of the left hippocampus compared with controls (P = 0.07). No statistically significant Inhibitors,research,lifescience,medical right versus left differences was found for either bilateral HS or AD. Discussion HS may be a dramatic finding at autopsy that often escaped clinical recognition and diagnosis during a given subject’s lifetime. In Inhibitors,research,lifescience,medical this convenience sample enriched for SIVD, AD, and normal aging, we found HS in 24.5% of autopsy cases. In our 31 cases, the laterality of HS showed significant variability: 45% were

bilateral, 32% left-sided, and 23% right-sided. The frequency of HS in our study was nearly Anacetrapib double the 12% previously reported in a community-based dementia autopsy series (Leverenz et al. 2002). Compared with the literature, our sample was intentionally enriched for SIVD, however, HS was found in roughly equal proportions in AD and SIVD (24% and 29%, respectively). More likely, the higher frequency of HS in our sample reflects the systematic examination of both hippocampi throughout their rostral–caudal extent in the majority of our cases. Indeed, based on our findings, the prevalence of HS will be underestimated by at least 25% if only one cerebral hemisphere is examined. We initially defined complete HS as involvement across multiple coronal sections.

17 Other studies have reported better survival in surgically trea

17 Other studies have reported better survival in surgically treated patients; however, it is impossible to exclude bias in many of these studies. Another possibility is the increased long-term toxicity from concurrent chemoradiation protocols, and an apparent trend toward increased death rates due to non-primary cancer-related causes.34 Further research will be required

in the coming years to elucidate the causes of this apparent decrease in larynx cancer survival, and/or better select patients for surgical versus non-surgical treatment. CONCLUSIONS The management Inhibitors,research,lifescience,medical of advanced laryngeal cancer has evolved toward a predominance of non-surgical strategies, in an endeavor to avoid the sequelae of total laryngectomy. This has been facilitated

by the development of modern chemoradiotherapy protocols with improved local control compared to radiotherapy alone. Ongoing challenges include development Inhibitors,research,lifescience,medical of strategies to reduce toxicity and adverse functional outcomes. Most very advanced (T4) laryngeal cancers are best treated with up-front total laryngectomy, due to the lower likelihood of response with non-surgical treatment. The role of total laryngectomy is increasingly as a salvage procedure for cases failing radiotherapy or chemoradiotherapy. Of increasing concern Inhibitors,research,lifescience,medical are reports of reduced survival among patients with laryngeal cancer, and speculation that this may be linked to recent changes Inhibitors,research,lifescience,medical in treatment paradigms.

Since the nineteenth century, when Kocher implemented the classical cervical thyroidectomy, little has changed in this procedure.1 When performed by experienced surgeons, the cervical approach is relatively short but unfortunately leaves a noticeable scar. Further advances in surgical instrumentation have introduced the minimally invasive thyroid Inhibitors,research,lifescience,medical surgery. The endoscopic thyroid surgery resulted in less morbidity and smaller surgical scars and developed into several different techniques.2 Nevertheless, Brefeldin_A the endoscopic cervical approach is surgically challenging since the neck is a very confined space and can be applied today to a small group of patients. The non-cervical, remote access choose size approaches originally developed unfortunately primarily due to cosmetic considerations—poor wound healing of certain ethnic groups and the aversion in the Asian culture to neck scars.3 Ikeda et al. in 2000 were the first to develop the transaxillary endoscopic approach to the thyroid.4 With the introduction of the Da Vinci robot (Intuitive Surgical, Sunnyvale, CA, USA), some surgeons have recognized its potential advantages. The South Korean team from Seoul, led by Chung, pioneered the transaxillary approach to the thyroid gland in late 2007.

31) In addition to the use of standard therapy for heart failure (diuretics, http://www.selleckchem.com/products/Enzastaurin.html vasodilators and digoxin), prolactin inhibition32) may provide potential benefit to patients with peripartum cardiomyopathy. Careful attention must be paid to select drugs relatively safe for mother and fetus and to exclude those that can evoke fetal abnormalities. The duration of treatment is still unknown. Though the majority of peripartum cardiomyopathy patients recover partially or are completely improved with treatment, the reported mortality rates lie between 18% and 56%.26),33)

Inhibitors,research,lifescience,medical Moreover, subsequent pregnancy in these patients can be associated with a recurrence of peripartum cardiomyopathy and can result in death.33) Stress-induced cardiomyopathy Inhibitors,research,lifescience,medical SCMP is a syndrome of reversible LV systolic dysfunction with characteristic apical ballooning in patients without significant epicardial coronary artery stenosis.10),34) This syndrome, also known as Takotsubo cardiomyopathy, is believed to be associated Inhibitors,research,lifescience,medical with various clinical scenarios, especially with intense mental or emotional stress.35) However, physical stress can cause this kind of cardiomyopathy. Park et al.35) reported their data of patients admitted to the medical intensive care unit.

They reported 28% of patients showed apical ballooning and they were usually Inhibitors,research,lifescience,medical associated with hypotension, sepsis, cardiomegaly and use of inotropic agents. SCMP occurs usually in

women over 50 years of age, and the typical features include profound mental stress immediately preceding and triggering the cardiac events, acute retrosternal chest pain with ST-segment change and/or T-wave inversion, absence of significant coronary artery stenosis by coronary angiography, and LV systolic dysfunction with abnormal wall motion of Inhibitors,research,lifescience,medical apex (apical ballooning).11) There is a variant of apical ballooning syndrome. Transient mid- and basal-ventricular ballooning is a new variant of the transient LV apical ballooning syndrome. The involvement of the LV’s mid- and basal-ventricle with sparing GSK-3 of the apical segment is the unique finding of this variant.36) Because the guideline excludes the presence of pheochromocytoma in the diagnosis of SCMP, the presence of a specific pattern with pheochromocytoma should be classified as catecholamine-induced cardiomyopathy.37) Echocardiography is a useful method to diagnose this type of cardiomyopathy. Transthoracic echocardiography usually demonstrates LV systolic dysfunction with typical apical ballooning and/or midventricular hypokinesia, and the wall-motion abnormality extends beyond the http://www.selleckchem.com/products/dorsomorphin-2hcl.html distribution of any of one single coronary artery.10),11) Transient LV hypokinesia can be restricted to the midventricular segment and/or basal segment without involvement of the apical segment in a minor population.

3 A block design study presented simultaneous visual and auditory stimuli to first-episode neuroleptic-naïve patients. Reduced activation in parietal lobes and right thalamus and prefrontal

cortex, implicated in the dorsal visual processing pathway, was observed in patients.10 Diminished activation in patients in prefrontal regions implicated in regulating inhibition was reported in a study of the inhibitory P300 for a NoGo condition.11 A three-stimulus auditory oddball task showed diffuse cortical and subcortical hypofunction during target detection and novelty processing in schizophrenia. Individuals with prodromal Inhibitors,research,lifescience,medical symptoms demonstrated smaller differential activation in frontal regions between relevant

and irrelevant stimuli.12 In a visual oddball study, patients and healthy Inhibitors,research,lifescience,medical participants showed activation patterns specific to Epigenetic Reader Do targets and novels, and activation of both neural systems was associated with faster performance.13 Specifically, reduced activation in regions involved in target and novelty processing in patients was accompanied by increased activation in circuits related to elaborated stimulus processing. For targets, abnormal activation was noted in regions related to ideational and visual association, and for novels Inhibitors,research,lifescience,medical patients overactivated sensory and frontal areas related to visualspatial processing and working memory ( Figure 2.) Thus, the attenuated electrophysiological response to targets seen in event-related potential studies may Inhibitors,research,lifescience,medical relate to insufficient

top-down activation of target circuitry, while the attenuated evoked response to novel distractors reflects over-processing of bottom-up events. Notably, abnormal activation in patients was associated with more severe symptoms. Figure 2. Examples of stimuli used in “oddball” studies of attentional processing (top) and contrast images of patients with schizophrenia and Inhibitors,research,lifescience,medical comparison subjects for target and novel stimuli. Greater activation in patients is depicted by the blue … Abnormal activation of frontotemporal regions has been further investigated in Sunitinib VEGFR relation to more complex downstream processes.5,6 Verbal learning deficits are well established in schizophrenia, and fMRI studies have consistently demonstrated abnormalities during the learning phase in frontotemporal circuits. Batimastat Most studies have reported decreased activation of the frontal cortex, especially the inferior prefrontal region, in schizophrenia. The data are less consistent with regard to the temporal lobe. Most studies have observed decreased activation in patients in the hippocampus and parahippocampal gyrus, but other studies have noted increased activation. As emphasized earlier, performance may be a contributing factor as the studies differ in their approach to performance. Event-related fMRI studies have shown deficits in working memory and cognitive control in schizophrenia.

According to a summary of data from these trials, the benefits of therapy defined as either the treatment effect (Figure 1) or the percentage of responders (Figure 2) have varied widely. To our knowledge, comparative studies of α1-blockers in patients with CP/CPPS

more recent studies have evaluated the third-generation uroselective Inhibitors,research,lifescience,medical agents tamsulosin and silodosin in patients with CP/CPPS.26,27 The third-generation agents are reported to have a higher affinity for the α1A-receptor, which is Inhibitors,research,lifescience,medical prevalent in human prostate tissues.13,33 Selectivity for the receptors in the prostate results in fewer adverse events mediated by α1B-receptor stimulation in the vasculature. For example, competitive binding experiments have found that the selectivity of silodosin is more than 100 times greater for the α1A than the α1B subtype, and that of tamsulosin is almost 10-fold Inhibitors,research,lifescience,medical greater with a moderate affinity for the α1D-subtype receptor.14 In those who receive treatment with second-generation α-adrenergic antagonists, postural hypotension and other cardiovascular side effects may be reduced by initiating treatment at the lowest starting dose, administering treatment at bedtime, and closely monitoring

blood pressure in patients who are receiving concomitant treatment with Inhibitors,research,lifescience,medical antihypertensive agents. Tamsulosin At this time, three prospective, placebo-controlled trials have evaluated the effects of the third-generation α-adrenergic antagonist tamsulosin as measured by the NIH-CPSI in patients with CP/CPPS.23,26,30 The most recent trial by Chen and colleagues was the first to evaluate the contain longer-term effects of an α1-blocker in a prospective, randomized Batimastat study.26 This placebo- controlled, prospective phase III study was conducted in 100 Chinese men with a ≥ 3-month history of pain or discomfort in the pelvic region who had not received prior treatment with α1-blockers.26 In this study, patients were randomized to treatment for 6 months with a low dose of tamsulosin (0.2 mg) or placebo to determine the effects of tamsulosin on symptom relief, as measured by change in NIH-CPSI during treatment and over a 2-year follow-up period.
