    Objective To describe and quantify the main changes seen on computed tomography of the chest in mildly symptomatic adult patients with sickle cell disease, as well as to evaluate the radiologist accuracy in determining the type of hemoglobinopathy. Materials and Methods A prospective study involving 44 adult patients with sickle cell disease who underwent inspiration and expiration computed tomography of the chest. The frequency of tomography findings and the extent of involvement are reported. We also calculated radiologist accuracy in determining the type of hemoglobinopathy by analyzing the pulmonary alterations and morphology of the spleen. Results The changes found on computed tomography scans, in descending order of frequency, were as follows: fibrotic opacities (81.8%); mosaic attenuation (56.8%); architectural distortion (31.8%); cardiomegaly (25.0%); lobar volume reduction (18.2%); and increased caliber of peripheral pulmonary arteries (9.1%). For most of the findings, the involvement was considered mild, five or fewer lung segments being affected. The accuracy in determining the type of hemoglobinopathy (HbSS group versus not HbSS group) was 72.7%. Conclusion In adult patients with sickle cell disease, the main tomography findings reflect fibrotic changes. In addition, computed tomography can be helpful in differentiating among hemoglobinopathies. PMID:27777473

    BACKGROUND Cardiac resynchronization therapy (CRT) reduces mortality, improves functional status, and induces reverse left ventricular remodeling in selected populations with heart failure (HF). The magnitude of reverse remodeling predicts survival with many HF medical therapies. However, there are few studies assessing the effect of remodeling on long-term survival with CRT. OBJECTIVE The purpose of this study was to assess the effect of CRT-induced reverse remodeling on long-term survival in patients with mildly symptomatic heart failure. METHODS The REsynchronization reVErses Remodeling in Systolic Left vEntricular Dysfunction trial was a multicenter, double-blind, randomized trial of CRT in patients with mild HF. Long-term follow-up of 5 years was preplanned. The present analysis was restricted to the 353 patients who were randomized to the CRT ON group with paired echocardiographic studies at baseline and 6 months post-implantation. The left ventricular end-systolic volume index (LVESVi) was measured in the core laboratory and was an independently powered end point of the REsynchronization reVErses Remodeling in Systolic Left vEntricular Dysfunction trial. RESULTS A 68% reduction in mortality was observed in patients with ≥15% decrease in LVESVi compared to the rest of the patients (P = .0004). Multivariable analysis showed that the change in LVESVi was a strong independent predictor (P = .0002), with a 14% reduction in mortality for every 10% decrease in LVESVi. Other remodeling parameters such as left ventricular enddiastolic volume index and ejection fraction had a similar association with mortality. CONCLUSION The change in left ventricular end-systolic volume after 6 months of CRT is a strong independent predictor of long-term survival in mild HF. PMID:25460860

    (1) Patients frequently complain of occasional bowel movement disorders, associated with abdominal pain or discomfort, but they are rarely due to an underlying organ involvement. Even when patients have recurrent symptoms, serious disorders are no more frequent in these patients than in the general population, unless other manifestations, anaemia, or an inflammatory syndrome is also present; (2) There is currently no way of radically modifying the natural course of recurrent irritable bowel syndrome; (3) The effects of antispasmodics on abdominal pain have been tested in about 20 randomised controlled trials. Pinaverium and peppermint essential oil have the best-documented efficacy and only moderate adverse effects. Antispasmodics with marked atropinic effects do not have a favourable risk-benefit balance; (4) Tricylic antidepressants seem to have only modest analgesic effects in this setting. In contrast, their adverse effects are frequent and they have somewhat negative risk-benefit balances. Nor has the efficacy of selective serotonin reuptake inhibitor antidepressants (SSRIs) been demonstrated; (5) Alosetron and tegaserod carry a risk of potentially life-threatening adverse effects and therefore have negative risk-benefit balances; (6) Seeds of plants such as psyllium and ispaghul, as well as raw apples and pears, have a limited impact on constipation and pain. Osmotic laxatives are effective on constipation. Symptomatic treatments for constipation can sometimes aggravate abdominal discomfort; (7) Loperamide has been poorly assessed in patients with recurrent irritable bowel syndrome with diarrhoea. It modestly slows bowel movement but does not relieve pain or abdominal discomfort; (8) Dietary measures have not been tested in comparative trials. Some patients are convinced that certain foods provoke a recurrence of irritable bowel syndrome, but restrictive diets carry a risk of nutritional deficiencies; (9) Various techniques intended to control emotional and

    Purpose: We investigated clinical and treatment-related factors as predictors of symptomatic pericardial effusion in esophageal cancer patients after concurrent chemoradiation therapy. Methods and Materials: We reviewed 214 consecutive primary esophageal cancer patients treated with concurrent chemoradiation therapy between 2001 and 2010 in our institute. Pericardial effusion was detected on follow-up computed tomography. Symptomatic effusion was defined as effusion ≥grade 3 according to Common Terminology Criteria for Adverse Events v4.0 criteria. Percent volume irradiated with 5 to 65 Gy (V5-V65) and mean dose to the pericardium were evaluated employing dose-volume histograms. To evaluate dosimetry for patients treated with two-dimensional planning in the earlier period (2001-2005), computed tomography data at diagnosis were transferred to a treatment planning system to reconstruct three-dimensional plans without modification. Optimal dosimetric thresholds for symptomatic pericardial effusion were calculated by receiver operating characteristic curves. Associating clinical and treatment-related risk factors for symptomatic pericardial effusion were detected by univariate and multivariate analyses. Results: The median follow-up was 29 (range, 6-121) months for eligible 167 patients. Symptomatic pericardial effusion was observed in 14 (8.4%) patients. Dosimetric analyses revealed average values of V30 to V45 for the pericardium and mean pericardial doses were significantly higher in patients with symptomatic pericardial effusion than in those with asymptomatic pericardial effusion (P<.05). Pericardial V5 to V55 and mean pericardial doses were significantly higher in patients with symptomatic pericardial effusion than in those without pericardial effusion (P<.001). Mean pericardial doses of 36.5 Gy and V45 of 58% were selected as optimal cutoff values for predicting symptomatic pericardial effusion. Multivariate analysis identified mean pericardial dose as the

    The reported prevalence of obstructive sleep apnea (OSA) in patients with syndromic craniosynostosis (SCS) varies due to inconsistent definitions of OSA, lack of uniform diagnostic testing, and different mixes of syndromic diagnoses. The purpose of this study was to determine the prevalence of OSA in symptomatic patients with SCS, and to determine whether this differs by phenotypic diagnosis. A retrospective cohort study of children with SCS was conducted. The primary outcome was presence of OSA diagnosed by polysomnography. The prevalence of OSA was calculated and stratified by diagnosis to compare differences in prevalence and severity (mild, moderate, or severe). The prevalence of OSA in symptomatic patients was 74.2%. Patients with Apert syndrome had the highest prevalence (80.6%), followed by Pfeiffer, Crouzon with acanthosis nigricans, and Crouzon syndromes (72.7%, 66.7%, and 64.7%, respectively). Severe OSA was most common in patients with Pfeiffer syndrome (45.5%), while patients with Apert and Crouzon syndromes were more likely to have moderate OSA (29.0% and 23.5%, respectively). Given that 56.4% of patients with SCS are symptomatic and that 74.2% of these symptomatic patients have OSA, it is recommended that a screening level I polysomnography be part of the clinical care for all patients with SCS.

    Background Venous thromboembolism (VTE) prophylaxis remains underutilized among hospitalized patients. We designed and carried out a large multicenter randomized controlled trial to test the hypothesis that an alert from a hospital staff member to the Attending Physician will reduce the rate of symptomatic VTE among high-risk patients not receiving prophylaxis. Methods and Results We enrolled patients using a validated point score system to detect hospitalized patients at high risk for symptomatic VTE who were not receiving prophylaxis. 2,493 patients (82% on Medical Services) from 25 study sites were randomized to the intervention group (n=1,238), in which the responsible physician was alerted by another hospital staff member, versus the control group (n=1,255), in which no alert was issued. The primary end point was symptomatic, objectively confirmed VTE within 90 days. Patients whose physicians were alerted were more than twice as likely to receive VTE prophylaxis as controls (46.0% versus 20.6%, p<0.0001). The symptomatic VTE rate was lower in the intervention group (2.7% versus 3.4%; hazard ratio, 0.79; 95% confidence interval, 0.50 to 1.25), but the difference did not achieve statistical significance. The rate of major bleeding at 30 days in the alert group was similar to the control group (2.1% versus 2.3%, p=0.68). Conclusions A strategy of direct staff member to physician notification increases prophylaxis utilization and leads toward reducing the rate of symptomatic VTE in hospitalized patients. However, VTE prophylaxis continues to be underutilized even after physician notification, especially among Medical Service patients. PMID:19364975

    Background Optimal treatment for patients with symptomatic intraluminal carotid thrombus (ICT) remains poorly defined. Methods We performed a retrospective chart review of patients presenting to our institution between 2001 and 2011 with symptomatic ICT. Results Twenty-four patients (16 males, 8 females) with ICT presented with ischemic stroke (n=18) or TIA (n=6). All were treated initially with anticoagulation ± antiplatelet drugs. Eight of these patients had no or mild carotid stenosis on initial angiography and were treated with medical management alone. The remaining 16 patients had moderate or severe carotid stenosis on initial angiography. Of these, 10 underwent delayed revascularization (endarterectomy, n=8; angioplasty and stenting, n=2), 2 refused revascularization, and 4 were treated with medical therapy alone. One patient had multiple TIAs despite medical therapy and eventually underwent CEA; the remaining 23 patients had no TIAs. No patient suffered ischemic or hemorrhagic stroke while on anticoagulation, during the perioperative period or in long-term follow up; one patient died of an unrelated condition (mean follow-up = 16.4 months). Conclusion Our results suggest that initial anticoagulation of symptomatic ICT results in a low rate of recurrent ischemic events and that carotid revascularization, if indicated, can be safely performed in a delayed manner.

    After nearly 40 years, carotid endarterectomy has been shown to be of benefit to patients with symptomatic carotid territory ischaemia and greater than 70% stenosis of the relevant internal carotid artery. Cerebral angiography is performed before surgery and is not without risk. These risks must be added to those of surgery before recommending the procedure to patients. The study evaluated the local, systemic and neurological complications following digital subtraction angiography with selective catheterisation of the carotid arteries in 200 patients presenting to a cerebrovascular clinic for assessment of cerebral ischaemia. All patients had carotid ultrasound screening before angiography to screen out those with normal arteries or mild disease (less than 30% stenosis of symptomatic internal carotid artery). Complications occurred in 28 patients. There were six (3%) local, two (1%) systemic and 20 (10%) neurological complications. Seventeen neurological complications occurred within 24 hours and there were three late complications (24-72 hours). Neurological complications occurred more frequently when angiography was performed by a trainee rather than a consultant neuroradiologist (p < 0.01). The neurological complications were transient (resolved within 24 hours) in 10/200 (5%), reversible (resolved within seven days) in two (1%) and permanent in 8/200 (4%). Two patients died after a stroke and two other patients suffered a disabling stroke. At 24 hours post angiography the permanent (persisting beyond seven days) neurological complication rate was 2.5%. The incidence of total neurological complications and post angiographic strokes was higher in patients with greater than 90% stenosis of the symptomatic internal carotid artery (p < 0.001). The increased use of non-invasive Doppler duplex screening will reduced the absolute number of patients put at risk of angiography, yet the rate of post angiographic complications is likely to increase as patients with severe

    All migraine patients need symptomatic treatment to stop individual attacks or, at least, significantly relieve pain. When attacks are very frequent (more than 3 days of headache per month on average), they will also need preventive treatment. The first physician the patient must address to for preventive treatment is the general practitioner (GP). If the medication prescribed by the GP is not effective or there is overuse of symptomatic drugs, the patient will have to be referred to a neurologist or a headache clinic. The drugs to be used as symptomatic treatment are triptans and non-steroidal anti-inflammatory drugs. Combination therapy with antiemetics is also important. While specialists will base their therapeutic decisions on guidelines in the literature and on their personal experience, GPs do not yet have any easy-to-use tools to support them. To fill this gap, an algorithm is proposed here that can be easily used by GPs to make decisions during their patients' migraine attacks.

    Of 120 patients presenting with mild bleeding disorders, 63 were found to have a definite coagulopathy. The commonest disorders were haemophilia, Christmas disease and von Willebrand's disease (vWd), the latter being predominant. Diagnosis led to prophylactic treatment prior to surgery in 18 patients with prevention of excessive haemorrhage. Three patients who had received blood products developed hepatitis. DDAVP (desamino-cys-1-8-D-arginine vasopressin) is the treatment of choice in suitable mildly affected patients with haemophilia A and vWd. Examination of blood group distribution suggests an excess of group O among patients with bleeding disorders, especially those with vWd.

    Patients with acute symptomatic pulmonary embolism (PE) who present with arterial hypotension or shock have a high risk of death (high-risk PE), and treatment guidelines recommend strong consideration of thrombolysis in this setting. For normotensive patients diagnosed with PE, risk stratification should aim to differentiate the group of patients deemed as having a low risk for early complications (all-cause mortality, recurrent venous thromboembolism, and major bleeding) (low-risk PE) from the group of patients at higher risk for PE-related complications (intermediate-high risk PE), so low-risk patients could undergo consideration of early outpatient treatment of PE and intermediate-high risk patients would undergo close observation and consideration of thrombolysis. Clinicians should also use risk stratification and eligibility criteria to identify a third group of patients that should not undergo escalated or home therapy (intermediate-low risk PE). Such patients should initiate standard therapy of PE while in the hospital. Clinical models [e.g., Pulmonary Embolism Severity Index (PESI), simplified PESI (sPESI)] may accurately identify those at low risk of dying shortly after the diagnosis of PE. For identification of intermediate-high risk patients with acute PE, studies have validated predictive models that use a combination of clinical, laboratory and imaging variables. PMID:26768476

    The aim of this study was to evaluate the incidence of secondary symptomatic vertebral compression fractures (VCFs) in patients previously treated by percutaneous vertebroplasty (VTP). Three hundred sixteen patients with 486 treated VCFs were included in the study according to the inclusion criteria. Patients were kept in regular follow-up using a standardized questionairre before, 1 day, 7 days, 6 months, and 1 year after, and, further on, on a yearly basis after VTP. The incidence of secondary symptomatic VCF was calculated, and anatomical distribution with respect to previous fractures characterized. Mean follow-up was 8 months (6-56 months) after VTP. Fifty-two of 316 (16.4 %) patients (45 female, 7 male) returned for treatment of 69 secondary VCFs adjacent to (35/69; 51%) or distant from (34/69; 49%) previously treated levels. Adjacent secondary VCF occurred significantly more often compared to distant secondary VCF. Of the total 69 secondary VCFs, 35 of 69 occurred below and 27 of 69 above pretreated VCFs. Of the 65 sandwich levels generated, in 7 of 65 (11%) secondary VCFs were observed. Secondary VCF below pretreated VCF occurred significantly earlier in time compared to VCF above and compared to sandwich body fractures. No major complication occurred during initial or follow-up intervention. We conclude that secondary VCFs do occur in individuals after VTP but the rate found in our study remains below the level expected from epidemiologic studies. Adjacent fractures occur more often and follow the cluster distribution of VCF as expected from the natural history of the underlying osteoporosis. No increased rate of secondary VCF after VTP was observed in this retrospective analysis. In accordance with the pertinent literature, short-term and also midterm clinical results are encouraging and provide further support for the usefulness and the low complication rate of this procedure as an adjunct to the spectrum of pain management in patients with severe

    Patients with advanced cancer may develop cachexia, which is often treated with megestrol acetate (MA). In addition to thromboembolic disease, MA may cause symptomatic suppression of the hypothalamic pituitary adrenal axis. In male patients with cancer, treatment with MA may also suppress the gonadal axis, resulting in symptomatic androgen deficiency. Three cases are presented to highlight the symptomatic burden of adrenal insufficiency and hypogonadism. Clinicians need an increased awareness of the complication of adrenal insufficiency secondary to MA treatment and a low threshold to test for adrenal and gonadal dysfunction in symptomatic male patients with advanced cancer.

    Lumbar spondylolysis, a stress fracture of the pars interarticularis, is prevalent in adolescent athletes. Recent advances in diagnostic tools and techniques enable early diagnosis before these fractures progress to complete fractures through the pars. However, because patients often consult family physicians for primary care of low back pain and these physicians may not have access to diagnostic modalities such as magnetic resonance imaging (MRI) and computed tomography, stress fractures can be missed. This study surveyed the prevalence of symptomatic spondylolysis in pediatric patients who consulted an orthopedic clinic for primary care and investigated whether such acute stress fractures may be overlooked without MRI. The prospective study investigated 264 patients who were younger than 19 years and had low back pain. Of the 153 patients (58.0%) with low back pain persisting for longer than 2 weeks, 136 who agreed to undergo MRI were included in the study. This group included 11 elementary school students, 71 junior high school students, and 54 high school students. The overall prevalence of lumbar spondylolysis was 39.7% (54 of 136) and was 9.3% in elementary school students (5 of 11, 45.5%), 59.3% in junior high school students (32 of 71, 45.1%), and 31.5% in high school students (17 of 54, 31.5%). All 54 patients with spondylolysis had a history of athletic activity. Primary care physicians should recognize that approximately 40% of pediatric patients presenting with low back pain persisting for longer than 2 weeks may have spondylolysis and should consider MRI in those with a history of athletic activity. Because the spine is immature in this age group, almost half of affected elementary school and junior high school students may have lumbar spondylolysis. [Orthopedics. 2016; 39(3):e434-e437.].

  15. Siltuximab (Sylvant). Castleman's disease: good symptomatic efficacy in some patients.

    PubMed

    2016-03-01

    Multicentric Castleman's disease is a rare lymphoproliferative disorder characterised by disseminated lymphadenopathy. Symptoms and outcomes differ widely from one patient to another. The median survival time is about 2.5 years. There is no consensus on treatment. Siltuximab, a monoclonal antibody that antagonises interleukin-6, has been authorised in the European Union for patients with multicentric Castleman's disease who are not infected with HIV or HHV-8. In a randomised, double-blind trial in 79 patients, most of whom had mild or moderate symptoms, the estimated one-year survival rate was 100% in the siltuximab group versus 92% in the placebo group after a median follow-up of 60 weeks. However, half of the patients in the placebo group received siltuximab after disease progression. Symptoms disappeared for at least 18 weeks in one-quarter of patients in the siltuximab group versus none of those in the placebo group; the median symptom-free period in the siltuximab group was about 16 months. The known adverse effects of siltuximab are related to its immunosuppressive effect. They include frequent infections, neutropenia and thrombocytopenia. Reactions can occur during the infusion, and mouth sores have been reported. Other adverse events that appear to be more frequent with siltuximab include cutaneous disorders, oedema, renal and cardiac disorders, and peripheral neuropathy. Cases of gastrointestinal perforation have been reported in trials in other clinical settings. Siltuximab can mask the signs and symptoms of acute inflammation, in particular by suppressing fever and acute-phase markers such as C-reactive protein. Interleukin-6 is a cytochrome P450 inhibitor. Siltuximab activates its isoenzymes and can thus reduce the effectiveness of the numerous drugs that are substrates of this enzyme system. This risk of interactions is likely to persist up to several weeks after siltuximab withdrawal, because of its long plasma elimination half-life (about 16 days

    BACKGROUND AND PURPOSE PCMR is used to evaluate the Chiari I malformation. We compared quantitative PCMR in symptomatic and asymptomatic patients with Chiari I. MATERIALS AND METHODS PCMR image data in an axial section near the foramen magnum in a consecutive series of patients with Chiari I malformations were evaluated. Patients were classified as symptomatic for a Chiari I if they had apnea spells and/or exertional headaches and as asymptomatic if they had symptoms not considered specific for a Chiari I malformation. The PCMR CSF flow study was obtained with the same protocol for all patients and with the neck in neutral, flexed, and extended positions. Images were inspected for CSF flow jets and synchronous bidirectional flow. Peak CSF flow velocities were calculated with commercial software. Differences between the 2 groups were tested with mixed-effects ANOVA and Wilcoxon rank sum or Fisher exact probability tests with significance set at the .05 level. RESULTS Twenty-six patients with Chiari I were classified as symptomatic, and 24, as asymptomatic. Abnormal flow jets tended to occur more often in the symptomatic than in the asymptomatic patients (P = .054). Peak CSF velocities ranged from 2 to 20 cm/s in the symptomatic and the asymptomatic groups and did not differ significantly between the 2 groups or with neck position. CONCLUSIONS Peak CSF flow velocities near the foramen magnum did not differentiate symptomatic and asymptomatic patients with Chiari I. PMID:20884747

    Radium-223 dichloride (Xofigo®; formerly Alpharadin™) [hereafter referred to as radium-223] is a first-in-class alpha particle-emitting radiopharmaceutical that has recently been approved for the treatment of patients with castration-resistant prostate cancer (CRPC) with symptomatic bone metastases and no known visceral metastatic disease. Radium-223 is a calcium mimetic, which targets bone, delivering cytotoxic radiation to the sites of bone metastases. In the recently reported Alpharadin™ in Symptomatic Prostate Cancer (ALSYMPCA) phase III study, radium-223 was associated with significantly improved overall survival compared with placebo, making it the first bone-targeted CRPC therapy for which an overall survival benefit has been demonstrated. The ALSYMPCA study also demonstrated the beneficial effects of radium-223 on disease-related symptomatic skeletal events, pain and health-related quality of life. Radium-223 was generally well tolerated, being associated with low rates of myelosuppression and generally mild gastrointestinal adverse events. Thus, radium-223 is a valuable addition to the treatment options for this poor-prognosis population.

    Objectives: Assess the worthiness of arthroscopy in investigating and treating knee pain after arthroplasty unexplained by clinical and subsidiary examinations. Methods: Among 402 patients submitted to total or unicompartimental arthroplasty between September 2001 and April 2007 at a public university hospital, 17 presented with pain on prosthetic articulation, without clear diagnosis by clinical, X-ray, laboratory, scintiscan, or nuclear magnetic resonance tests. All patients were submitted to arthroscopy and symptoms were assessed by using the Lysholm scale, comparing pre-and post-arthroscopy periods. Peroperative findings have been recorded. Results: The procedure was effective for pain relief in 14 of 17 patients (82.35%). The median for Lysholm scale climbed from 36 points before arthroscopy to 94 points after the procedure (p < 0.001). Most of the patients (12) were arthroscopically diagnosed with fibrosis known as “cyclop”; on the remaining five patients, anterior synovitis was found. All patients were treated by resection. Conclusions: Knee arthroscopy after arthroplasty in patients presenting unclear persistent pain shows localized arthrofibrosis (“cyclops”) or synovitis, which can be treated by using the same procedure, resulting in pain relief.

    Both schizophrenia and bipolar disorder (BD) have consistently been associated with deficits in facial affect recognition (FAR). These impairments have been related to various aspects of social competence and functioning and are relatively stable over time. However, individuals in remission may outperform patients experiencing an acute phase of the disorders. The present study directly contrasted FAR in symptomatically remitted patients with schizophrenia or BD and healthy volunteers and investigated its relationship with patients' outcomes. Compared to healthy control subjects, schizophrenia patients were impaired in the recognition of angry, disgusted, sad and happy facial expressions, while BD patients showed deficits only in the recognition of disgusted and happy facial expressions. When directly comparing the two patient groups individuals suffering from BD outperformed those with schizophrenia in the recognition of expressions depicting anger. There was no significant association between affect recognition abilities and symptomatic or psychosocial outcomes in schizophrenia patients. Among BD patients, relatively higher depression scores were associated with impairments in both the identification of happy faces and psychosocial functioning. Overall, our findings indicate that during periods of symptomatic remission the recognition of facial affect may be less impaired in patients with BD than in those suffering from schizophrenia. However, in the psychosocial context BD patients seem to be more sensitive to residual symptomatology.

    Objectives: The objective of this study was to identify the location and magnitude of difference in acetabular rim morphology between the symptomatic and asymptomatic acetabula in a cohort of patients with symptomatic unilateral pincer-type FAI. Methods: After IRB approval, computed tomography (CT) scans of 43 patients (22 males, 21 females) diagnosed with unilateral pincer-type FAI were obtained. CT images of both hips were imported in DICOM format and segmented into 3-dimensional (3D) hemi-pelvises using 3D reconstruction software (Mimics, Materialise, Leuven, Belgium). The point-cloud data of the asymptomatic hemi-pelvis was mirrored onto the symptomatic side. Protrusion of the symptomatic side was recorded as a positive value and appeared as red on the color map (Figure 1). Data was collected in 3° intervals and analyzed by quadrant using the clock face method; reflecting the 12-3, 3-6, 6-9, and 9-12 o’clock positions. Results: The symptomatic acetabular rim was on average 0.39 ± 0.36 mm thicker than the corresponding location on the asymptomatic rim. When the acetabular clock face was broken up into quadrants, reflecting the 12-3, 3-6, 6-9, and 9-12 o’clock positions, the 12-3 o’clock position demonstrated the greatest difference between symptomatic and asymptomatic sides (Table 1). The 12-3 o’clock quadrant demonstrated significantly greater difference between symptomatic and asymptomatic sides (0.53±0.22 mm) as compared to the 3-6 o’clock position (0.39±0.27 mm; p=0.006), the 6-9 o’clock position (0.34±0.05 mm; p<0.001), and the 9-12 o’clock position (0.33±0.03; p<0.001). There was no correlation between gender and magnitude of difference at any location. Conclusion: Small changes in acetabular rim morphology, on the order of 0.5 mm or less can be the difference between symptomatic pincer-type FAI and the asymptomatic state. Knowledge of the healthy, unaffected side in unilateral FAI may provide a better template for rim recession rather

    Background/Aims We investigated writing abilities in patients with the amnestic type of mild cognitive impairment (aMCI) and mild Alzheimer's disease (AD). To examine the earliest changes in writing function, we used writing tests for both words and sentences with different types of Japanese characters (Hiragana, Katakana, and Kanji). Methods A total of 25 aMCI patients, 38 AD patients, and 22 healthy controls performed writing to dictation for Kana and Kanji words, copied Kanji words, and wrote in response to a picture story task. Analysis of variance was used to test the subject group effects on the scores in the above writing tasks. Results For the written Kanji words, the mild AD group performed worse than the aMCI group and the controls, but there was no difference between the aMCI group and the controls. For the picture story writing task, the mild AD and aMCI groups performed worse than the controls, but the difference between the AD and the aMCI groups was not significant. Conclusions The mild AD group showed defects in writing Kanji characters, and the aMCI group showed impairments in narrative writing. Our study suggests that narrative writing, which demands complex integration of multiple cognitive functions, can be used to detect the subtle writing deficits in aMCI patients. PMID:26483830

    We examined the relationship between cumulative body mass index (BMI) and symptomatic, psychosocial, and medical outcomes in patients with borderline personality disorder (BPD). Two hundred female borderline patients were weighed and measured during their index admission. They were subsequently interviewed at six, eight, and 10 years intervals. Over 10 years of prospective follow-up, increases in cumulative BMI were significantly associated with self-mutilation and dissociation (but not suicide attempts). Increases in cumulative BMI were also significantly associated with having no life partner, a poor work or school history, being on disability, being rated with a GAF score in the fair or poor range, and having a low income. In addition, increases in BMI were related to having two or more obesity-related medical conditions and using costly forms of health care. Increases in cumulative BMI may be a marker for adverse symptomatic, functional, and medical outcomes in patients with BPD. PMID:21838559

    Filarial parasites infect an estimated 140 million people worldwide. Wuchereria bancrofti, Onchocerca volvulus, Loa loa and Mansonella perstans are responsible for most filarial infections in sub-Saharan Africa. We describe the prevalence and the clinical characteristics of filariasis in symptomatic patients in Goundi Sanitary district:167 patients were enrolled (99 men, 68 women). M. perstans microfilariae were isolated in peripheral blood in 164 cases, while Loa loa and Wuchereria bancrofti filariasis were diagnosed in only six and three cases, respectively. The most frequent filariasis observed in our study were due to M. perstans and L. loa, while the few cases of W. bancrofti filariasis seem to have been acquired abroad. No cases of O. volvulus were observed. Microfilarial burden was not related to symptoms, but a correlation between eosinophilia and pruritus was evident. No relationship was observed between eosinophils and symptoms. The prevalence observed in symptomatic patients could reflect the real prevalence of filariasis. PMID:17716512

    AIMS: To evaluate whether endometrial pathology is more likely to be diagnosed in gynaecologically symptomatic rather than in gynaecologically asymptomatic postmenopausal breast cancer patients with tamoxifen treatment; and to evaluate the possible influence of various clinical factors on the incidence of endometrial pathology. METHODS: Endometrial histological findings, transvaginal ultrasonographic endometrial thickness, demographic characteristics, health habits, and risk factors for endometrial cancer were compared between 14 gynaecologically symptomatic (group I) and 224 gynaecologically asymptomatic (group II) postmenopausal breast cancer patients with tamoxifen treatment. RESULTS: Overall, 28.6% of the study population had endometrial pathology. The incidence of overall positive endometrial histological findings was significantly higher in group I than in group II (92.9% v 24.6%, p < 0.0001). Atrophic endometrium was more common in group II than in group I (75.3% v 7.1%, p < 0.0001). Most other endometrial pathology was significantly more common in group I than in group II (endometrial hyperplasia, 35.7% v 5.6%, p < 0.0001; endometrial polyps, 35.7% v 13.4%, p < 0.0111; endometrial carcinoma, 21.5% v 0.9%, p < 0.0001). Endometrial pathology appeared considerably later in the gynaecologically asymptomatic patients than in gynaecologically symptomatic patients (p = 0.0002). Vaginal bleeding or spotting occurred exclusively in group I. The incidence of endometrial pathology in the entire study population was consistent with that reported elsewhere, and higher than that reported for healthy postmenopausal women. CONCLUSIONS: Endometrial pathology is more likely to be diagnosed in gynaecologically symptomatic postmenopausal breast cancer patients with tamoxifen treatment, and after a shorter duration of time, than in gynaecologically asymptomatic patients.

    It is essential to image the carotid bifurcation adequately in patients with symptomatic carotid territory ischaemia if they are being considered for carotid endarterectomy. Optimal resolution is achieved by selective intraarterial contrast angiography which is an invasive procedure carrying some risk. The overall risk-benefit of carotid endarterectomy is currently being investigated in several large randomised trials in Europe and North America. Because cerebral angiography is a prerequisite for carotid endarterectomy, the risks of cerebral angiography will need to be added to those of surgery when considering whether carotid endarterectomy is effective in the management of these patients. This study evaluated prospectively 382 patients with symptomatically mild carotid ischaemia who had cerebral angiography to visualise a potentially resectable lesion at the carotid bifurcation. Complications followed 14 cerebral angiograms in 13 patients (3.4%); two complications were local (0.5%), two systemic (0.5%) and 10 were neurological (2.6%). The neurological complications were transient (TIA 1, generalised seizure 1) in two patients (0.5%), reversible (stroke) in three (0.8%) and permanent (stroke) in five patients (1.3%). There were no deaths. The significant risk factors for post angiographic stroke were (1) stroke before angiography compared with transient ischaemic attacks of the eye or brain and (2) the presence of greater than or equal to 50% diameter stenosis of the symptomatic internal carotid artery; unfortunately it may be the latter patients who are most at risk of stroke as part of the natural history of their disease and therefore most in need of prophylactic carotid endarterectomy (which requires cerebral angiography).

    A prospective series of 50 neurologically symptomatic human immunodeficiency infected patients with intracranial lesions who underwent image-guided stereotactic brain biopsy is presented. Patients were diagnosed with primary central nervous system lymphoma (14 patients), progressive multifocal leukoencephalopathy (14 patients), toxoplasmosis (13 patients), human immunodeficiency virus encephalitis (3 patients), infarction (2 patients), and 1 patient each with metastatic adenocarcinoma, metastatic melanoma, cryptococcoma, and atypical mycobacterial infection. Two of the patients with toxoplasmosis had a second intracranial abnormality. Two biopsies resulted in either descriptive diagnosis only or were nondiagnostic; the definitive diagnostic efficacy of image-guided stereotactic biopsy was thus 96%. No deaths were incurred as a result of biopsy. Four intraoperative or postoperative hemorrhages occurred; in only 1 patient was there a residual neurological deficit related to the surgery. Image-guided stereotactic biopsy may thus be considered both safe and effective in this patient population.

    Constipation, diarrhea, and symptomatic hemorrhoids are disorders common in the general population, particularly in women. These conditions, if mild, often are self-treated with various home remedies or nonprescription preparations. Few of these patients, moreover, are referred to gastroenterologists, as primary care providers generally are confident managing these conditions, unless they are severe, refractory to conventional management, or require additional diagnostic studies.

    Between January 1988 and December 1990, 283 patients with symptomatic gall stones were referred for non-operative treatment. After ultrasound scanning including a functional assessment, 220 (78%) patients were found to be suitable for percutaneous cholecystolithotomy. Of these, 113 underwent the procedure including 10 in whom extracorporeal shock-wave lithotripsy or methyl tert-butyl ether therapy had failed. Forty four patients underwent extracorporeal shockwave lithotripsy, methyl tert-butyl ether therapy or rotary lithotripsy, 46 chose laparoscopic cholecystectomy or minicholecystectomy and 27 declined treatment. Percutaneous cholecystolithotomy was successfully performed in 100 patients. Thirty four patients were a high operative risk and 14 presented with an acute complication of gall stone disease. Complications developed in 15 patients, all of whom were managed conservatively and most occurred during development of the technique. Outcome has been assessed clinically and by ultrasound scanning in 92 patients with a median follow up period of 14 months (six to 37 months). Seventy nine per cent were completely cured of their symptoms. Ninety three per cent of gall bladders were shown to be functioning and nine (9.8%) contained stones, although five of these are believed to have developed from residual fragments. Percutaneous cholecystolithotomy is a safe, non-operative treatment for symptomatic gall stones and enabled the patient to fully recover within two to three weeks; it has a definite role in the management of the elderly and high risk patient but its use for the treatment of other groups is likely to remain controversial.

    In the psychiatric treatment of patients with mild learning disabilities or borderline intellectual functioning, signs and symptoms of psychiatric disorders are sometimes misinterpreted as behaviour that reflects problems that are known to patients with mental retardation. We report on two case studies in which lithium therapy made a substantial contribution to (partial) recovery. One patient had bipolar disorder and the other had a major depressive disorder combined with suicidal behaviour. Each patient also had a mild learning disability or borderline intellectual functioning. PMID:26189422

    To explore the associated risk factors of symptomatic knee osteonecrosis (KON) in patients with systemic lupus erythematosus (SLE), we conducted a retrospective case-control study to compare the clinical and laboratory features between SLE patients with and without symptomatic KON matched by age and gender. Univariate and multivariate regression analyses were used to evaluate possible associated risk factors. Twenty (one male, nineteen females) out of 3941 lupus patients were identified as symptomatic KON, which was confirmed by magnetic resonance imaging. The mean age at KON onset was 34.4 (range 12-67) years, and the median course of lupus at KON onset was 72.5 (range 8-123) months. Univariate and multivariate analyses identified that the prevalence of cutaneous vasculitis (OR 5.23; 95 % CI 1.11-24.70), hyperfibrinogenemia (OR 4.75; 95 % CI 1.08-20.85), and elevated IgG levels (OR 6.05; 95 % CI 1.58-23.16) were statistically higher in KON group, and hydroxychloroquine (HCQ) usage was statistically lower in KON group (OR 0.27; 95 % CI 0.07-0.97). Glucocorticoid usage, in terms of maximal dose, duration of treatment, and the percentage of receiving methylprednisolone pulse therapy, did not show statistical difference between the two groups (p > 0.05). Symptomatic KON is a relatively rare complication of SLE. Cutaneous vasculitis, hyperfibrinogenemia, and elevated IgG levels are possible risk factors, whereas HCQ may provide a protective effect. Our results suggest that lupus activity as well as hypercoagulation status may play a role in the pathogenesis of KON in lupus. PMID:27230994

    Background Although the prevalence of full-thickness rotator cuff tears increases with age, many patients are asymptomatic and may not require surgical repair. The factors associated with pain and loss of function in patients with rotator cuff tears are not well defined. Purpose To determine which factors correlate with pain and loss of function in patients with symptomatic, atraumatic full-thickness rotator cuff tears who are enrolled in a structured physical therapy program. Study Design Cross-sectional study; Level of evidence, 3. Methods A multicenter group enrolled patients with symptomatic, atraumatic rotator cuff tears in a prospective, nonrandomized cohort study evaluating the effects of a structured physical therapy program. Time-zero patient data were reviewed to test which factors correlated with Western Ontario Rotator Cuff (WORC) index and American Shoulder and Elbow Surgeons (ASES) scores. Results A total of 389 patients were enrolled. Mean ASES score was 53.9; mean WORC score was 46.9. The following variables were associated with higher WORC and ASES scores: female sex (P = .001), education level (higher education, higher score; P <.001), active abduction (degrees; P = .021), and strength in forward elevation (P = .002) and abduction (P = .007). The following variables were associated with lower WORC and ASES scores: male sex (P = .001), atrophy of the supraspinatus (P = .04) and infraspinatus (P = .003), and presence of scapulothoracic dyskinesia (P < .001). Tear size was not a significant predictor (WORC) unless comparing isolated supraspinatus tears to supraspinatus, infraspinatus, and subscapularis tears (P = .004). Age, tear retraction, duration of symptoms, and humeral head migration were not statistically significant. Conclusion Nonsurgically modifiable factors, such as scapulothoracic dyskinesia, active abduction, and strength in forward elevation and abduction, were identified that could be addressed nonoperatively with therapy.

    90 percent of symptomatic patients undergoing cholecystectomy have cholelithiasis with 10% categorized as asymptomatic cholecystitis. In both instances, the gallbladder is evident on ultrasonography. In children with symptomatic biliary dyspepsia, the decision to proceed to cholecystectomy is made difficult if choleliths are not seen on ultrasonography. This decision is made even more difficult if the gallbladder itself is not seen on repeated imaging. In a cohort of 54 cholecystectomies, 3 cases, with recurrent right upper quadrant pain and undetectable gallbladders on repeat ultrasonography, were identified. After prolonged observation all underwent successful cholecystectomy. Histology demonstrated a markedly fibrotic and thickened gallbladder in all. Given this experience, we suggest that nonvisibility of the gallbladder, in fact, maybe be a feature of a chronic acalculous cholecystitis. We advise consideration of cholecystectomy for chronic biliary dyspepsia where repeat ultrasonography fails to demonstrate a gallbladder. PMID:23401761

    Purpose: To evaluate the safety and outcome of ovarian artery embolization (OAE) in patients with collateral supply to symptomatic uterine leiomyomata. Materials and Methods: Thirteen patients with relevant leiomyoma perfusion by way of enlarged ovarian arteries underwent additional OAE during the same (N = 10) or a second procedure (N = 3). Uterine artery embolization (UAE) was performed bilaterally in 10 and unilaterally in 2 patients with a single artery. One patient had no typical uterine arteries but bilaterally enlarged ovarian arteries, prompting bilateral OAE. OAE was accomplished with coil embolization in one and particle embolization in 12 patients. Symptoms before therapy and clinical outcome were assessed using a standardized questionnaire. Contrast-enhanced magnetic resonance (MR) imaging after embolization was available in 11 of 13 patients and was used to determine the percentage of fibroid infarction. Results: UAE and OAE were technically successful in all patients. One patient experienced prolonged irritation at the puncture site. Median clinical follow-up time was 16 months (range 4-37). Ten of 13 patients showed improvement or complete resolution of clinical symptoms. One patient reported only slight improvement of her symptoms. These women presented with regular menses. Two patients (15%), 47 and 48 years, both with unilateral OAE, reported permanent amenorrhea directly after embolization. Their symptoms completely resolved. Seven patients showed complete and 4 showed >90% fibroid infarction after embolization therapy. Conclusions: OAE is technically safe and effective in patients with ovarian artery collateral supply to symptomatic uterine leiomyomata. The risk of permanent amenorrhea observed in this study is similar to the reported incidence after UAE.

    2011-01-01

    Background Observational studies have previously shown that adverse events following manipulation to the neck and/or back are relatively common, although these reactions tend to be mild in intensity and self-limiting. However, no prospective study has examined the incidence of adverse reactions following spinal adjustments using upper cervical techniques, and the impact of this care on clinical outcomes. Methods Consecutive new patients from the offices of 83 chiropractors were recruited for this practice-based study. Clinical outcome measures included 1) Neck pain disability index (100-point scale), 2) Oswestry back pain index (100-point scale), 3) 11-point numerical rating scale (NRS) for neck, headache, midback, and low back pain, 4) treatment satisfaction, and 5) Symptomatic Reactions (SR). Data were collected at baseline, and after approximately 2 weeks of care. A patient reaching sub-clinical status for pain and disability was defined as a follow-up score <3 NRS and <10%, respectively. A SR is defined as a new complaint not present at baseline or a worsening of the presenting complaint by >30% based on an 11-point numeric rating scale occurring <24 hours after any upper cervical procedure. Results A total of 1,090 patients completed the study having 4,920 (4.5 per patient) office visits requiring 2,653 (2.4 per patient) upper cervical adjustments over 17 days. Three hundred thirty- eight (31.0%) patients had SRs meeting the accepted definition. Intense SR (NRS ≥8) occurred in 56 patients (5.1%). Outcome assessments were significantly improved for neck pain and disability, headache, mid-back pain, as well as lower back pain and disability (p <0.001) following care with a high level (mean = 9.1/10) of patient satisfaction. The 83 chiropractors administered >5 million career upper cervical adjustments without a reported incidence of serious adverse event. Conclusions Upper cervical chiropractic care may have a fairly common occurrence of mild intensity SRs

    Background Hip abductor tendon (HAT) tearing is commonly implicated in greater trochanteric pain syndrome (GTPS), though limited information exists on the disability associated with this condition and specific presentation of these patients. Purpose To describe the clinical, functional and biomechanical presentation of patients with symptomatic HAT tears. Secondary purposes were to investigate the association between these clinical and functional measures, and to compare the pain and disability reported by HAT tear patients to those with end-stage hip osteoarthritis (OA). Study Design Prospective case series. Methods One hundred forty-nine consecutive patients with symptomatic HAT tears were evaluated using the Harris (HHS) and Oxford (OHS) Hip Scores, SF-12, an additional series of 10 questions more pertinent to those with lateral hip pain, active hip range of motion (ROM), maximal isometric hip abduction strength, six-minute walk capacity and 30-second single limb stance (SLS) test. The presence of a Trendelenburg sign and pelvis-on-femur (POF) angle were determined via 2D video analysis. An age matched comparative sample of patients with end-stage hip OA was recruited for comparison of all patient-reported outcome scores. Independent t-tests investigated group and limb differences, while analysis of variance evaluated pain changes during the functional tests. Pearson's correlation coefficients investigated the correlation between clinical measures in the HAT tear group. Results No differences existed in patient demographics and patient-reported outcome scores between HAT tear and hip OA cohorts, apart from significantly worse SF-12 mental subscale scores (p = 0.032) in the HAT tear group. Patients with HAT tears demonstrated significantly lower (p < 0.05) hip abduction strength and active ROM in all planes of motion on their affected limb. Pain significantly increased throughout the 30-second SLS test for the HAT tear group, with 57% of HAT tear patients

    Background The adverse effects of tobacco abuse on cardiovascular outcomes are well-known. However, the impact of passive smoke exposure on angina status and therapeutic response is less well-established. We examined the impact of second-hand smoke (SHS) exposure on symptomatic improvement in patients with chronic ischemic coronary disease undergoing enhanced external counterpulsation (EECP). Methods This observational study included 1,026 non-smokers (108 exposed and 918 not-exposed to SHS) from the Second International EECP Patient Registry. We also assessed angina response in 363 current smokers. Patient demographics, symptomatic improvement and quality of life assessment were determined by self-report prior and after EECP treatment. Results Non-smoking SHS subjects had a lower prevalence of prior revascularization (85% vs 90%), and had an increased prevalence of stroke (13% vs 7%) and prior smoking (72% vs 61%; all p < 0.05) compared to non-smokers without SHS exposure. Despite comparable degrees of coronary disease, baseline angina class, medical regimens and side effects during EECP, fewer SHS non-smokers completed a full 35-hour treatment course (77% vs 85%, p = 0.020) compared to non-smokers without SHS. Compared to non-smokers without SHS, non-smoking SHS subjects had less angina relief after EECP (angina class decreased ≥ 1 class: 68% vs 79%; p = 0.0082), both higher than that achieved in current smokers (66%). By multivariable logistic regression, SHS exposure was an independent predictor of failure to symptomatic improvement after EECP among non-smokers (OR 1.81, 95% confidence intervals 1.16–2.83). Conclusion Non-smokers with SHS exposure had an attenuated improvement in anginal symptoms compared to those without SHS following EECP. PMID:18798998

    BACKGROUND. The high transmissibility and widespread environmental contamination by Clostridium difficile suggests the possibility of airborne dissemination of spores. We measured airborne and environmental C. difficile adjacent to patients with symptomatic C. difficile infection (CDI). METHODS. We conducted air sampling adjacent to 63 patients with CDI for 180 h in total and for 101 h in control settings. Environmental samples were obtained from surfaces adjacent to the patient and from communal areas of the ward. C. difficile isolates were characterized by ribotyping and multilocus variable-number tandem-repeat analysis to determine relatedness. RESULTS. Of the first 50 patients examined (each for 1 h), only 12% had positive air samples, most frequently those with active symptoms of CDI (10%, vs 2% for those with no symptoms). We intensively sampled the air around 10 patients with CDI symptoms, each for 10 h over 2 days, as well as a total of 346 surface sites. C. difficile was isolated from the air in the majority of these cases (7 of 10 patients tested) and from the surfaces around 9 of the patients; 60% of patients had both air and surface environments that were positive for C. difficile. Molecular characterization confirmed an epidemiological link between airborne dispersal, environmental contamination, and CDI cases. CONCLUSIONS. Aerosolization of C. difficile occurs commonly but sporadically in patients with symptomatic CDI. This may explain the widespread dissemination of epidemic strains. Our results emphasize the importance of single-room isolation as soon as possible after the onset of diarrhea to limit the dissemination of C. difficile.

    Laparoscopic cholecystectomy (LC) has the advantages of early return to full daily activity, early return to work, and better cosmetic result, as well as quickly resolving pain. Yet how this information about the procedure influences a patient's attitude toward laparocopy is not known. In this study we analyzed the factors that play role in the decision-making process of patients who choose laparoscopic surgery, and we also evaluated patients' knowledge of laparoscopy and their expectations. A questionnaire was used in evaluating 98 patients suffering from symptomatic cholelithiasis scheduled for elective laparoscopic cholecystectomy between January 2001 and January 2002. Females constituted 81% of the study population. Most of the patients (56%) were housewives. While 45% of the patients had an educational status of primary school degree only, 14% had graduated from a university. Forty-three patients described their level of knowledge about laparoscopy as "low" (had only heard about laparoscopy). In 61% of the patients the surgeon was the sole decision maker about the type of the operation. Almost none of the patients had a preference for the time of discharge from the hospital after surgery, and only three of the actively working patients offered a time interval for return to work. From this study we concluded that most patients have inadequate information about laparoscopic surgery, that the type of operation is dictated mostly by the surgeon, and that early discharge and early return to work are not important for many patients.

    Venous thromboembolism (VTE) is a common preventable cause of mortality during hospitalization. However, prophylaxis is frequently under-utilized due to the belief that it is rare in Asia. The objective of the study was to estimate the incidence of symptomatic VTE in hospitalized nonsurgical Thai patients. We performed a prospective study in medical wards in Chulalongkorn Hospital, a tertiary care university-based center, from June 2007 to December 2008. We included adult patients admitted beyond 3 days. Patients with VTE before admissions or undergoing major surgery during hospitalization were excluded. According to the usual practice, heparin prophylaxis was not given. However, the program of primary physician education and fast-track diagnostic imaging were implemented. Forty-two VTEs from 7126 susceptible patients [0.59%, 95% confidence interval (CI) 0.41-0.77%] were found; 20 (48%) definite pulmonary embolism, four of which also had symptomatic deep vein thrombosis (DVT), 19 (45%) definite DVT and three sudden deaths from possible pulmonary embolism. Immobilization (74%), active cancer (52%) and rheumatologic diseases (12%), including arthritis of lower extremities and systemic lupus erythematosus with antiphospholipid, were common VTE risk factors, which were present in our patients. The incidences in total cases of arthritis, cancer, mechanical ventilation and congestive heart failure were 7.7, 1.8, 1.5 and 0.5%, respectively. Notably, nine of 23 (39%) pulmonary embolism cases were fatal and two more patients (9.5%) expired from bleeding after treatment (one pulmonary embolism and one DVT). In conclusion, VTE contributes significant hazard to hospitalized nonsurgical Thai patients. Appropriate measures to assure proper thromboprophylaxis in high-risk patients are strongly needed.

    The incidence of bronchiectasis (BCT) has probably decreased in developed countries in recent years, but reliable statistical data on its occurrence are still lacking. The aim of the present study was to retrospectively evaluate the prevalence, age distribution and aetiology of BCT, diagnosed in a selected series of symptomatic patients of a Western country by using bronchography. The authors analysed the main known predisposing and associated conditions (PACs), and the occurrence and age distribution of BCT in 144 consecutive patients who underwent bronchological examination (fibreoptic bronchoscopy and bronchography) in the years 1987-1994 because of recurrent purulent bronchitis and/or haemoptysis. The overall prevalence of BCT was 34% (49/144); its age distribution was: 17.2% (0-10 yrs), 43.7% (11-20 yrs), 38% (21-30 yrs), 37.5% (31-40 yrs), 33.3% (41-50 yrs), 40% (51-60 yrs), and 20% (61-70 yrs). Thirty-one PACs were found in 29/144 patients of the whole study group. The prevalence of BCT was significantly higher in the subgroup of 29 patients with PACs than in the subgroup of 115 patients without PACs (75.9% versus 23.5%; p < 0000001). The aetiology of BCT was mainly unexplained, as it was only possible to detect 24 PACs in 22/49 patients with BCT (44.9%): congenital, genetic and immune disorders (eight), localized airways obstructive diseases (five), pulmonary infections (three), bronchial asthma (two), pulmonary lobar fibrosis (two), ulcerative colitis (two), dermatomiositis (one), and toxin inhalation (one). The authors conclude that bronchiectasis still occurs in a large percentage of symptomatic patients of a developed country in the post-antimicrobial era, especially in the second to sixth decades, as well as in the presence of predisposing and associated conditions; its aetiology remains unknown in more than half of cases.

    Wechsler Adult Intelligence Scale-III (WAIS-III) and Wechsler Memory Scale-III (WMS-III; The Psychological Corporation, 1997) scores of patients with mild traumatic brain injury (MTBI, n = 23) to moderate-severe traumatic brain injury (M-S TBI, n = 22) were compared to those of 45 matched normal control patients. WAIS-III results revealed that IQ and index scores of MTBI patients did not significantly differ from those of controls, whereas M-S TBI patients received significantly lower mean scores on all measures. All M-S TBI patients' WMS-III index scores also revealed significantly lower scores in comparison to those of control participants, with the exception of Delayed Auditory Recognition. MTBI patients showed significantly lower mean index scores compared to normal controls on measures of immediate and delayed auditory memory, immediate memory, visual delayed memory, and general memory. Eta-squared analyses revealed that WMS-III visual indexes and WAIS-III processing speed showed particularly large effect sizes. These results suggest that symptomatic MTBI patients obtain some low WMS-III test scores comparable to those of more severely injured patients.

    The purpose of this study was to find the circulating microRNAs (miRNAs) co-related with the severity of coronary artery calcification (CAC), and testify whether the selected miRNAs could reflect the obstructive coronary artery disease in symptomatic patients. Patients with chest pain and moderated risk for coronary artery disease (CAD) were characterized with coronary artery calcium score (CACS) from cardiac computed tomography (CT). We analyzed plasma miRNA levels of clinical matched 11 CAC (CACS > 100) and 6 non-CAC (CACS = 0) subjects by microarray profile. Microarray analysis identified 34 differentially expressed miRNAs between CAC and non CAC groups. Eight miRNAs (miR-223, miR-3135b, miR-133a-3p, miR-2861, miR-134, miR-191-3p, miR-3679-5p, miR-1229 in CAC patients) were significantly increased in CAC plasma in an independent clinical matched cohort. Four miRNAs (miR-2861, 134, 1229 and 3135b) were correlated with the degree of CAC. Validation test in angiographic cohort showed that miR-134, miR-3135b and miR-2861 were significantly changed in patients with obstructive CAD . We identified three significantly upregulated circulating miRNAs (miR-134, miR-3135b and 2861) correlated with CAC while detected obstructive coronary disease in symptomatic patients. PMID:26537670

  3. Characteristics of Symptomatic Intracranial Hemorrhage in Patients Receiving Non-Vitamin K Antagonist Oral Anticoagulant Therapy

    2015-01-01

    Objectives The first non-vitamin K antagonist oral anticoagulant (NOAC) introduced to the market in Japan was dabigatran in March 2011, and three more NOACs, rivaroxaban, apixaban, and edoxaban, have since become available. Randomized controlled trials of NOACs have revealed that intracranial hemorrhage (ICH) occurs less frequently with NOACs compared with warfarin. However, the absolute incidence of ICH associated with NOACs has increased with greater use of these anticoagulants, and we wanted to explore the incidence, clinical characteristics, and treatment course of patients with NOACs-associated ICH. Methods We retrospectively analyzed the characteristics of symptomatic ICH patients receiving NOACs between March 2011 and September 2014. Results ICH occurred in 6 patients (5 men, 1 woman; mean ± SD age, 72.8 ± 3.2 years). Mean time to onset was 146.2 ± 111.5 days after starting NOACs. Five patients received rivaroxaban and 1 patient received apixaban. None received dabigatran or edoxaban. Notably, no hematoma expansion was observed within 24 h of onset in the absence of infusion of fresh frozen plasma, activated prothrombin complex concentrate, recombinant activated factor VIIa or hemodialysis. When NOAC therapy was initiated, mean HAS-BLED and PANWARDS scores were 1.5 ± 0.5 and 39.5 ± 7.7, respectively. Mean systolic blood pressure was 137.8 ± 15.9 mmHg within 1 month before spontaneous ICH onset. Conclusion Six symptomatic ICHs occurred early in NOAC therapy but hematoma volume was small and did not expand in the absence of infusion of reversal agents or hemodialysis. The occurrence of ICH during NOAC therapy is possible even when there is acceptable mean systolic blood pressure control (137.8 ± 15.9 mmHg) and HAS-BLED score ≤ 2. Even stricter blood pressure lowering and control within the acceptable range may be advisable to prevent ICH during NOAC therapy. PMID:26171862

    Mild cognitive impairment (MCI) is a unique entity in the spectrum of syndromes of cognitive loss. Many patients referred for evaluation of memory loss come with an assumption that they already have dementia. When patients are diagnosed with MCI, they and their caregivers have to deal with the challenge of uncertainties. Patient and family education must stress the uncertainty of whether the deficits will progress. This article aims to guide the clinician who has reached a diagnosis of MCI and is working with the patient and family on coping with the uncertainties of MCI.

The results of the study prove significant positive effects of the preparation used. A significant improvement of FEV1 and PEF values was observed, as well as a statistically significant remission of both day and nocturnal symptoms of the disease, a significantly lower consumption of short-acting beta2-sympathomimetics, and an improvement of all evaluated data relating to the quality of life of the asthmatic patients.

    Hypermagnesemia is an uncommon but a potentially serious clinical condition. Over-the-counter magnesium containing products are widely used as antacids or laxatives. Although generally well tolerated in patients with normal renal function, their unsupervised use in the elderly can result in severe symptomatic hypermagnesemia, especially in those patients with concomitant renal failure and bowel disorders. We report a case of severe symptomatic hypermagnesemia associated with over-the-counter laxatives in a 70-year-old male patient with renal failure and sigmoid volvulus, who was successfully treated with hemodialysis.

    Type 1 von Willebrand disease and mild platelet function defects are among the most common disorders seen by pediatric hematologists. The management and prevention of bleeding in these patients can be challenging, as there are limited published data to guide clinical practice, and a complete lack of randomized clinical trials. Desmopressin (DDAVP) and antifibrinolytics are the mainstays of treatment in these patients, yet the optimal dosing and timing of these agents to prevent or resolve bleeding, while minimizing adverse side effects, is sometimes unclear. DDAVP-induced hyponatremia is a particularly under-recognized complication in children with bleeding disorders who undergo surgery. Clinicians need to be aware of local measures that are equally important in treating problems such as epistaxis and surgical bleeding. This review will discuss the published literature and provide practical suggestions regarding four common management issues in the care of children and adolescents with mild bleeding disorders: epistaxis, heavy menstrual bleeding, dental extractions, and tonsillectomy.

    One hundred sixteen patients were evaluated to determine the ability of single photon emission computed tomographic (SPECT) thallium-201 exercise and redistribution imaging to detect silent ischemia secondary to restenosis in asymptomatic patients after single and multiple vessel percutaneous transluminal coronary angioplasty and the findings were compared with SPECT imaging detection of restenosis in symptomatic patients. The value of exercise electrocardiography (ECG) and the amount of ischemic myocardium in symptomatic and asymptomatic patients were determined. Forty-one patients were asymptomatic after angioplasty; 77% of these had chest pain before angioplasty. Seventy-five patients had chest pain after angioplasty; 99% of these had chest pain before angioplasty. Restenosis occurred in 61% of asymptomatic and 59% of symptomatic patients and in 46% of the vessels in both asymptomatic and symptomatic patients. Sensitivity, specificity and accuracy for detection of restenosis by SPECT in individual patients were 96%, 75% and 88% versus 91%, 77% and 85%, respectively, in the asymptomatic versus symptomatic groups (p = NS). Sensitivity, specificity and accuracy for restenosis detection in individual vessels were 90%, 89% and 89% versus 84%, 77% and 84%, respectively, in the asymptomatic and symptomatic groups (p = NS), with similar results for the three major arteries. Sensitivity and accuracy of exercise ECG were significantly less than those of SPECT imaging for the patients with silent (40% and 44%) and symptomatic (59% and 64%) ischemia (p less than 0.001). Restenosis of vessels in the patients with silent and symptomatic ischemia was associated with an equal amount and degree of severity of ischemic myocardium in the two groups.

    Our purpose was to examine the effect of modifying symptomatic movement and alignment tests in a sample of people with LBP referred to physical therapy. Fifty-one patients (19 males, 32 females; mean age 37±10.59 y) with LBP and a mean Oswestry Disability Index score of 34±18% were examined. The examination included 28 primary tests in which patients used their preferred movement or alignment strategy and reported symptoms. Symptomatic tests were followed by a secondary test in which the patient’s strategy was standardly modified to correct the spinal alignment or movement that occurred with the primary test. Symptoms and directions of movement or alignment modified were recorded. For 82% of the secondary tests, the majority of the patients’ symptoms improved. For 54% of the secondary tests, some patients required modification of more than one direction of movement or alignment to eliminate symptoms. The findings suggest that the modifications described are generalizable across a number of tests with a moderately involved group of patients, and for individual tests there is variability in the numbers and directions of movements or alignments that appear to contribute to symptoms. Information obtained from the modifications is important because it can be used to confirm the patient’s LBP classification and, within the context of the examination, immediately be used to teach the patient strategies to change movements and positions that appear to be contributing to his LBP.

    Breast cancer is the most common malignancy in Singapore women. Ductal carcinoma in situ (DCIS) is the putative, non-obligate precursor of the majority of invasive breast cancers. The efficacy of the Singapore breast-screening pilot project in detecting early stage breast cancer led to the launch of a national breast-screening programme, BreastScreen Singapore (BSS), in January 2002. In this study, we compared clinicopathological and immunohistochemical characteristics, as well as clinical outcomes, between screen-detected and symptomatic DCIS. The study cohort comprised 1202 cases of DCIS diagnosed at Singapore General Hospital from 1994 to 2010. Comparison of clinicopathological parameters, immunohistochemical results of ER, PR, HER2, CK14, EGFR, and 34βE12, and clinical outcomes was carried out between the 2 groups. Amongst 1202 cases, 610 (50.7%) were screen-detected and 592 (49.3%) were symptomatic DCIS. Screen-detected cases were smaller in size (P < 0.001), of lower nuclear grade (P = 0.004), and more frequently expressed ER (P < 0.001). Luminal A phenotype was more frequently observed in screen-detected DCIS, while triple-negative and HER2 phenotypes were more common in symptomatic DCIS (P < 0.001). The basal-like phenotype was also more frequent in symptomatic DCIS (P = 0.041). Mean and median follow-up was 99.7 and 97.8 months, respectively, with a maximum follow-up of 246.0 months. More symptomatic patients developed invasive recurrences compared to screen-detected patients (P = 0.001). A trend for better disease-free survival was observed in screen-detected patients (P = 0.076). Patients who were screen-detected experienced better overall survival than those with symptomatic DCIS (P = 0.007). Our data indicate a more favourable outcome of screen-detected DCIS patients confirming the role of BSS in early identification of this curable disease.

    Alzheimerś disease (AD) is a progressive irreversible neurological brain disorder characterized by accumulation of amyloid-β, amyloid plaques, and neurofibrillary tangles. Inflammation and immune alterations have been linked to AD, suggesting that the peripheral immune system plays a role during the asymptomatic period of AD. NK cells participate in innate immune surveillance against intracellular pathogens and malignancy but their role in AD remains controversial. We have investigated changes in peripheral NK cell phenotypes and functions in amnestic mild cognitive impairment (aMCI, n = 10), patients with mild AD (mAD, n = 11), and healthy elderly controls (n = 10). Patients selected according to NINCDS-ADRDA criteria were classified using neuropsychological assessment tests. Phenotype analysis revealed differences in expression of CD16 (increased in mAD), NKG2A (decreased in aMCI), and TLR2 and TLR9 (both decreased in mAD). Functional assays revealed that NK cell killing activity and degranulation (CD107 expression) were unchanged in the three groups. In contrast, expression of the CD95 receptor was increased in aMCI and mAD. Granzyme B expression and cytokine production (TNFα, IFNγ) were increased in aMCI but not in mAD. CCL19- but not CCL21-dependent chemotaxis was decreased in aMCI and mAD, despite the fact that CCR7 expression was increased in aMCI. Our data suggest that the number of alterations observed in peripheral NK cells in aMCI represent an activation state compared to mAD patients and that may reflect an active immune response against a still to be defined aggression.

    Abstract Background: Clarithromycin is often a component of combination therapies for Helicobacter pylori eradication; however, increases in resistance rates have decreased the success of the treatment. Objective: This study was designed to determine the prevalence of H pylori infection in symptomatic patients and to detect clarithromycin resistance rates using melting curve analysis. Methods: Patients scheduled for upper endoscopy at the Endoscopy Unit of the Department of Gastroenterology, Duzce University, Medical Faculty Hospital, Konuralp/Duzce, Turkey, were assessed for enrollment in the study. Two pairs of gastric biopsy specimens (antrum and corpus) were obtained from each study patient. Histopathologic examination, rapid urease test, culture, and polymerase chain reaction (PCR) of the specimens were used to identify H pylori infection. Clarithromycin resistance was detected using melting curve analysis. Results: Seventy-five patients (41 women, 34 men; mean [SD]age, 42.6 [14.5] years [range, 17–70 years]) were included in the study. Using histopathology and rapid urease test, H pylori was detected in 40 (53.3%) of the 75 specimens. H pylori was detected using PCR in 40 (53.3%) specimens and by culture in 10 (13.3%) specimens. The specificity and sensitivity of PCR and culture were interpreted by comparing them with the results of histopathologic examination and urease tests. The specificity and sensitivity of PCR were 68.6% and 72.5%, respectively, and the specificity and sensitivity of culture were 97.1% and 22.5%, respectively. Of the 40 isolates, 21 (52.5%) were susceptible to clarithromycin, 12 (30.0%) were resistant, and a mixed susceptibility pattern was detected in 7 (17.5%) specimens. H pylori isolates from 19 (79.2%) of the 24 patients who had formerly used clarithromycin showed clarithromycin resistance. Conclusions: The prevalence of H pylori infection was 53.3% for the symptomatic patients in this study, and 47.5% of the isolates showed

    Greater trochanteric pain syndrome (GTPS) is a common complaint. Recently, it has become well recognized that tendinopathy and tears of the gluteus medius (GM) are a cause of recalcitrant GTPS. Nevertheless, the clinical syndrome associated with GM tears is not fully characterized. We characterize the clinical history, findings on physical examination, imaging and intraoperative findings associated with symptomatic GM tears. Forty-five patients (47 hips) who underwent GM repair for the diagnosis of tear were evaluated. Pain was estimated on the visual analog scale (VAS) and hip-specific scores were administered to assess functional status. The imaging modalities were reviewed and intra operative findings were recorded. The average patient age was 54 years (17–76), 93% were females. Symptom onset was commonly insidious (75%) and the average time to diagnosis was 28 months (2–240). The most common pain location was the lateral hip (75%). The average pre-surgery VAS and modified Harris Hip Score were 6.65 (0–10) and 55.5 (12–90), respectively. All patients had pathological findings on magnetic resonance angiogram (MRA) ranging from tendinosis to complete tears of the GM tendon. There was a discrepancy between MRA interpretation by a radiologist and findings during surgery. Hip abductor tears are an under-recognized cause of hip pain and hip symptomatology. In this study, we further characterize the clinical presentation of this entity. The data we present here may facilitate early diagnosis, early orthopedic care and avoid unnecessary prolonged patient sufferings. PMID:27011854

    The diagnosis of cancer is a complex, multi-step process. In this paper, we highlight factors involved in missed opportunities to diagnose cancer more promptly in symptomatic patients and discuss responsible mechanisms and potential strategies to shorten intervals from presentation to diagnosis. Missed opportunities are instances in which post-hoc judgement indicates that alternative decisions or actions could have led to more timely diagnosis. They can occur in any of the three phases of the diagnostic process (initial diagnostic assessment; diagnostic test performance and interpretation; and diagnostic follow-up and coordination) and can involve patient, doctor/care team, and health-care system factors, often in combination. In this perspective article, we consider epidemiological 'signals' suggestive of missed opportunities and draw on evidence from retrospective case reviews of cancer patient cohorts to summarise factors that contribute to missed opportunities. Multi-disciplinary research targeting such factors is important to shorten diagnostic intervals post presentation. Insights from the fields of organisational and cognitive psychology, human factors science and informatics can be extremely valuable in this emerging research agenda. We provide a conceptual foundation for the development of future interventions to minimise the occurrence of missed opportunities in cancer diagnosis, enriching current approaches that chiefly focus on clinical decision support or on widening access to investigations.

    Background and objectives: Optimal hemoglobin targets for chronic kidney disease patients receiving erythropoiesis-stimulating agents remain controversial. The effects of different hemoglobin targets on blood transfusion requirements have not been well characterized, despite their relevance to clinical decision-making. Design, setting, participants, & measurements: Five hundred ninety-six incident hemodialysis patients without symptomatic cardiac disease were randomly assigned to hemoglobin targets of 9.5 to 11.5 g/dl or 13.5 to 14.5 g/dl for 96 wk using epoetin alfa as primary therapy and changes in left ventricular structure as the primary outcome (previously reported). Patients were masked to treatment assignment. Blood transfusion data were prospectively collected at 4-wk intervals. Results: The mean age and prior duration of dialysis therapy of the study population were 50.8 and 0.8 yr, respectively. Previously reported mortality was similar in low and high-target subjects, at 4.7 (95% confidence interval 3.0, 7.3) and 3.1 (1.8, 5.4) per hundred patient years, respectively. Transfusion rates were 0.66 (0.59, 0.74) units of blood per year in low and 0.26 (0.22, 0.32) in high-target subjects (P < 0.0001). Hemoglobin level at transfusion (7.7 [7.5, 7.9]) versus 8.1 [7.6, 8.5] g/dl) were similar with both groups. High hemoglobin target was a significant predictor of time to first transfusion independent of baseline associations (hazard ratio = 0.42; 95% confidence interval = 0.26 − 0.67). Conclusions: In hemodialysis patients with comparatively low mortality risks, normal hemoglobin targets may reduce the need for transfusions. PMID:18922988

    Background: Atherosclerotic coronary artery disease (CAD) has long been shown to involve chronic low-grade subclinical inflammation. However, whether there is association between hematological indices assessed by complete blood count (CBC) and coronary atherosclerotic burden has not been well studied. Materials and Methods: Consecutive 868 patients without known CAD who presented with acute chest pain to emergency department and underwent coronary artery calcium (CAC) scoring evaluation by multi-detector cardiac computed tomography were included in our study. Clinical characteristics and CBC indices were compared among different CAC groups. Results: The cohort comprised 60% male with a mean age of 61 (SD = 14) years. Median Framingham risk of CAD was 4% (range 1-16%). Median CAC score was 0 (IQR 0-43). Higher CAC groups had significantly higher Framingham risk of CAD than lower CAC groups (P < 0.001). Among different CAC categories, there was no statistically significant difference in hemoglobin level (p 0.45), mean corpuscular volume (p 0.43), mean corpuscular hemoglobin (p 0.28), mean corpuscular hemoglobin volume (p 0.36), red cell distribution width (0.42), total white blood cell counts (p 0.291), neutrophil counts (p 0.352), lymphocyte counts (p 0.92), neutrophil to lymphocyte ratio (p 0.68), monocyte count (p 0.48), and platelet counts (p 0.25). Conclusion: Our study did not detect significant association between hematological indices assessed with CBC and coronary calcification in symptomatic patients without known CAD. PMID:25317386

    Plasticity-based spontaneous recovery and rehabilitation intervention of stroke-induced hemianopia have drawn great attention in recent years. However, the underlying neural mechanism remains unknown. This study aims to investigate brain network disruption and reorganization in hemianopia patients due to mild occipital stroke. Resting-state networks were constructed from 12 hemianopia patients with right occipital infarct by partial directed coherence analysis of multi-channel electroencephalograms. Compared with control subjects, the patients presented enhanced connectivity owing to newly formed connections. Compensational connections mostly originated from the peri-infarct area and targeted contralesional frontal, central, and parietal cortices. These new ipsilesional-to-contralesional inter-hemispheric connections coordinately presented significant correlation with the extent of vision loss. The enhancement of connectivity might be the neural substrate for brain plasticity in stroke-induced hemianopia and may shed light on plasticity-based recovery or rehabilitation. PMID:24876132

    Background: Early diagnosis of familial transthyretin (TTR) amyloid diseases remains challenging because of variable disease penetrance. Currently, patients must have an amyloid positive tissue biopsy to be eligible for disease-modifying therapies. Endomyocardial biopsies are typically amyloid positive when cardiomyopathy is suspected, but this disease manifestation is generally diagnosed late. Early diagnosis is often difficult because patients exhibit apparent symptoms of polyneuropathy, but have a negative amyloid biopsy. Thus, there is a pressing need for an additional early diagnostic strategy for TTR-aggregation-associated polyneuropathy and cardiomyopathy. Methods and Findings: Global peripheral blood cell mRNA expression profiles from 263 tafamidis-treated and untreated V30M Familiar Amyloid Neuropathy patients, asymptomatic V30M carriers, and healthy, age- and sex-matched controls without TTR mutations were used to differentiate symptomatic from asymptomatic patients. We demonstrate that blood cell gene expression patterns reveal sex-independent, as well as male- and female-specific inflammatory signatures in symptomatic FAP patients, but not in asymptomatic carriers. These signatures differentiated symptomatic patients from asymptomatic V30M carriers with >80% accuracy. There was a global downregulation of the eIF2 pathway and its associated genes in all symptomatic FAP patients. We also demonstrated that the molecular scores based on these signatures significantly trended toward normalized values in an independent cohort of 46 FAP patients after only 3 months of tafamidis treatment. Conclusions: This study identifies novel molecular signatures that differentiate symptomatic FAP patients from asymptomatic V30M carriers as well as affected males and females. We envision using this approach, initially in parallel with amyloid biopsies, to identify individuals who are asymptomatic gene carriers that may convert to FAP patients. Upon further validation

    Abstract We designed a retrospective cohort study to assess sex-related differences in clinical manifestations, incidence, and outcomes of patients with symptomatic acute aortic dissection (AAD). We collected clinical data from 2010 to 2015 of 400 patients with AAD. Patients’ clinical characteristics, treatment, and outcomes were analyzed as a function of sex. Among 400 patients with AAD, the ratio of men to women was 3.18:1; the incidence of atherosclerosis was higher in women (P = 0.02). Dysphoria (P = 0.01), focal neurological deficits (P = 0.04), and pulse deficits (P = 0.03) were more frequent in men. Imaging findings revealed that pleural effusion (P < 0.01), celiac trunk involvement (P < 0.01), and superior mesenteric artery involvement (P = 0.02) were more frequent in men. Dissection-related pneumonia (P = 0.02), pulmonary atelectasis (P = 0.01), aortic intramural hematoma (P < 0.01), ischemic electrocardiographic changes (P = 0.03), and in-hospital complications such as myocardial ischemia (P = 0.03), hypoxemia (P < 0.01), cardiac tamponade (P = 0.01) occurred more frequently in women. Women with type A dissection had higher in-hospital mortality than men (P < 0.01). The presentation of AAD varies with a patient's sex. Women with AAD had clinical features different from men as follows: higher age of onset, more frequent inpatient complications, and higher in-hospital mortality. These findings may lead to a better understanding of aortic dissection in women that will improve their outcomes. PMID:26986151

    Purpose Umeclidinium/vilanterol (UMEC/VI) is a novel fixed dose combination of a long-acting muscarinic receptor antagonist (LAMA) and a long-acting beta 2 receptor antagonist (LABA) agent. This analysis evaluated the incremental cost-effectiveness ratio (ICER) of UMEC/VI compared with tiotropium (TIO), from the Spanish National Health System (NHS) perspective. Methods A previously published linked equations cohort model based on the epidemiological longitudinal study ECLIPSE (Evaluation of COPD Longitudinally to Identify Predictive Surrogate End-points) was used. Patients included were COPD patients with a post-bronchodilator forced expiratory volume in 1 second (FEV1) ≤70% and the presence of respiratory symptoms measured with the modified Medical Research Council dyspnea scale (modified Medical Research Council ≥2). Treatment effect, expressed as change in FEV1 from baseline, was estimated from a 24-week head-to-head phase III clinical trial comparing once-daily UMEC/VI with once-daily TIO and was assumed to last 52 weeks following treatment initiation (maximum duration of UMEC/VI clinical trials). Spanish utility values were derived from a published local observational study. Unitary health care costs (€2015) were obtained from local sources. A 3-year time horizon was selected, and 3% discount was applied to effects and costs. Results were expressed as cost/quality-adjusted life years (QALYs). Univariate and probabilistic sensitivity analysis (PSA) was performed. Results UMEC/VI produced additional 0.03 QALY and €590 vs TIO, leading to an ICER of €21,475/QALY. According to PSA, the probability of UMEC/VI being cost-effective was 80.3% at a willingness-to-pay of €30,000/QALY. Conclusion UMEC/VI could be considered as a cost-effective treatment alternative compared with TIO in symptomatic COPD patients from the Spanish NHS perspective. PMID:26848262

    Purpose. To evaluate the mid-term clinical results and patient satisfaction following uterine artery embolization (UAE) in women with symptomatic fibroids. Methods. Between August 1998 and December 2002, 135 patients had UAE for symptomatic uterine fibroids. All patients were asked to fill in a questionnaire. Questions were aimed at changes in bleeding, pain, and bulk-related symptoms. Symptoms after UAE were scored as disappeared, improved, unchanged or worsened. Adverse events were noted, such as vaginal dryness and discharge, menopausal complaints or fibroid expulsion. Patient satisfaction after UAE was assessed. Patient satisfaction of women embolized with polyvinyl alcohol (PVA) particles was compared with satisfaction of women embolized with calibrated microspheres. Results. The questionnaire was returned by 110 of 135 women (81%) at a median time interval of 14 months following UAE. In 10 women additional embolization or hysterectomy had been performed. Of the 110 responders, 86 (78%) were satisfied with the result of UAE. The proportion of satisfied women was higher in the group embolized with calibrated microspheres than in women embolized with PVA, although this difference was not statistically significant (p = 0.053). Conclusion. UAE in women with symptomatic uterine fibroids leads to improvement of symptoms and patient satisfaction is good in the vast majority after a median follow-up period of 14 months.

    To demonstrate that amyotrophic lateral sclerosis (ALS) is not a neurodegenerative disease. The patient, a 33-year-old man began with symptoms of the bulbar form of ALS, characterized by burning pain in both feet during two months and then, he presented right crural monoparesis, fasciculations, slight dysarthria and he walked with help of orthopedic devices. A preoperative MRI scans showed atherosclerosis at the V4 segment of the left vertebral artery. On May 2012, he received an omental transplantation on the anterior, left lateral and posterior surface of the medulla oblongata. About 48 hours after surgery, the dysarthria disappeared and the voluntary movement of the right foot improved. Three days later, he walked without aid of orthopedic device. At present, four years after operation he present complete reversal of symptoms. In conclusión, this patient confirms that bulbar ALS is of ischemic origin and therefore, mild ALS can be cured.

    Background and Purpose— Intracranial atherosclerosis is a major cause of ischemic stroke worldwide. Intracranial vessel wall imaging is an upcoming field of interest to assess intracranial atherosclerosis. In this study, we investigated total intracranial plaque burden in patients with symptomatic middle cerebral artery stenosis, assessed plaque morphological features, and compared features of symptomatic and asymptomatic lesions using a 3T vessel wall sequence. Methods— Nineteen consecutive Chinese patients with ischemic stroke and transient ischemic attack (mean age: 67 years; 7 females) with a middle cerebral artery stenosis were scanned at 3T magnetic resonance imaging; the protocol included a time-of-flight magnetic resonance angiography and the T1-weighted volumetric isotropically reconstructed turbo spin echo acquisition sequence before and after (83%) contrast administration. Chi-square tests were used to assess associations between different plaque features. Statistical significance was set at P<0.05. Results— Vessel wall lesions were identified in 18 patients (95%), totaling 57 lesions in 494 segments (12% of segments). Lesions were located primarily in the anterior circulation (82%). Eccentric lesions were associated with a focal thickening pattern and concentric lesions with a diffuse thickening pattern (P<0.001). When differentiating between asymptomatic and symptomatic lesions, an association (P<0.05) was found between eccentricity and asymptomatic lesions, but not for enhancement or a specific thickening pattern. Symptomatic lesions did not have any specific morphological features. Conclusions— Our results lead to a 2-fold conclusion: (1) The classification system of both thickening pattern and distribution of the lesion can be simplified by using distribution pattern only and (2) differentiation between symptomatic and asymptomatic atherosclerotic lesions was possible using intracranial vessel wall imaging.

    Conclusions Patients with symptomatic perforations of the nasal septum had a high prevalence of S. aureus in the nasal mucosa. Pulsed field gel electrophoresis (PFGE) analysis revealed a high genetic heterogeneity of S. aureus among both patients and controls. This indicates that presence of different strains of S. aureus can maintain a chronic inflammation in symptomatic nasal septal perforations. Objective The purpose of this study was to investigate the microbial flora around nasal septal perforations in patients having severe symptoms regarding bleeding, obstruction, and crustation associated with their perforation. Methods Twenty-five patients with untreated symptomatic nasal septal perforations were included. For culture, swabs around the perforations were collected. Bacteria were identified with standard laboratory techniques including a MALDI-TOF mass spectrometer. Epidemiological analysis was done using PFGE protocols. Bacteriological data were compared with data from a healthy control group. Results Staphylococcus aureus was present in the mucosa surrounding the nasal perforation significantly more often (p < 0.0001) in the patients (88%) compared to a control group (13%). Corynebacterium spp. and Propionibacterium spp. were significantly more frequently identified in the control group. The PFGE analysis of S. aureus strains revealed a high genetic heterogeneity and no specific S. aureus genotypes were associated with septal perforation. PMID:26852671

    In this study the authors examine whether smoking further heightens platelet activity and reduces fibrinolysis above that already present in mild hypertension. Ten smokers and 11 non-smokers, all with mild hypertension (defined as a diastolic pressure between 90 and 110 mm Hg) were compared for their platelet activity in vitro and in vivo and for their fibrinolytic activity. Successive measurements were made with the patients lying at rest after they had assumed the erect posture for 10 min and at the end of a 5-min moderately strenuous exercise test. The threshold for platelet aggregation by ADP in vitro was significantly lower in samples taken from the smokers at rest (1.4 +/- 0.9 mumol L(-1)) than in the non-smokers (3.5 +/- 2.5 mumol L(-1)), and the difference persisted both in the upright posture and after exercise. The level of platelet release of beta-thromboglobulin was, likewise, higher in the smokers in the upright posture. Neither standing up nor physical exercise had any significant influence on either of these two indices of platelet activity. The euglobulin clot lysis time was slightly longer in the smokers than in the non-smokers in all three experimental situations, but the differences were not significant. Inhibitor of tissue plasminogen activator was not materially different in the two groups (Table 2). The results indicate that smoking adds a further element of heightened platelet activity to that inherently present in hypertension.

    Introduction: The aim of this randomized-controlled clinical trial was to assess the effect of intraligamentary (PDL) injection of dexamethasone on onset and severity of post-treatment pain in patients with symptomatic irreversible pulpitis. Methods and Materials: A total number of 60 volunteers were included according to the inclusion criteria and were assigned to three groups (n=20). After administration of local anesthesia and before treatment, group 1 (control) PDL injection was done with syringe containing empty cartridge, while in groups 2 and 3 the PDL injection was done with 0.2 mL of 2% lidocaine or dexamethasone (8 mg/2 mL), respectively. Immediately after endodontic treatment patients were requested to mark their level of pain on a visual analogue scale (VAS) during the next 48 h (on 6, 12, 24 and 48-h intervals). They were also asked to mention whether analgesics were taken and its dosage. Considering the 0-170 markings on the VAS ruler, the level of pain was scored as follows: score 0 (mild pain; 0-56), score 1 (moderate pain; 57-113) and score 3 (severe pain; 114-170). The data were analyzed using the Kruskal-Wallis and the Chi-square tests and the level of significance was set at 0.05. Results: After 6 and 12 h, group 1 and group 3 had the highest and lowest pain values, respectively (P<0.01 and P<0.001 for 6 and 12 h, respectively). However, after 24 and 48 h the difference in the pain was not significant between groups 1 and 2 (P<0.6) but group 3 had lower pain levels (P<0.01 and P<0.8 for 24 and 48 h, respectively). Conclusion: Pretreatment PDL injection of dexamethasone can significantly reduce the post-treatment endodontic pain in patients with symptomatic irreversible pulpitis. PMID:27790253

    We sought to investigate whether carotid endarterectomy (CEA) can achieve long-term cerebral hemodynamic improvement and reduce recurrence of cerebral ischemic events in symptomatic and asymptomatic patients with severe (>70%) carotid artery stenosis contralateral to carotid occlusion (CO). Thirty-nine patients with severe carotid lesion contralateral to CO were studied before (1 day) and after CEA (at 7 days, 1, 3 and 6 months, and then yearly thereafter). Collateral flow and cerebral vasomotor reactivity (VMR) were assessed by transcranial Doppler sonography (TCD). A total of 32 unoperated patients with severe carotid lesion contralateral to CO, who were comparable with respect to age and sex, served as a control group. The average period of TCD follow-up was 10 years and was obtained in all patients; during this period, major clinical events (stroke, acute myocardial infarction and death) were also recorded. The proportion of patients with collateral flow via the anterior communicating artery increased significantly from 61.5% before to 89.7% after CEA (P = 0.01). Cerebral VMR ipsilateral to CO improved in 85.7% of patients (30 of 35) within 30 days of CEA, and in all patients within 90 days. No significant spontaneous VMR recovery was recorded in the control group. After the initial recovery, no significant change in VMR was observed in the surgical group or the control group during the follow-up. In conclusion, in patients with severe carotid stenosis, CEA contralateral to symptomatic and asymptomatic CO determines a durable cerebral hemodynamic improvement not only on the side of the CEA but also on the contralateral side, with no difference between symptomatic and asymptomatic patients.

  10. The vascular steal phenomenon is an incomplete contributor to negative cerebrovascular reactivity in patients with symptomatic intracranial stenosis.

    'Vascular steal' has been proposed as a compensatory mechanism in hemodynamically compromised ischemic parenchyma. Here, independent measures of cerebral blood flow (CBF) and blood oxygenation level-dependent (BOLD) magnetic resonance imaging (MRI) responses to a vascular stimulus in patients with ischemic cerebrovascular disease are recorded. Symptomatic intracranial stenosis patients (n=40) underwent a multimodal 3.0T MRI protocol including structural (T1-weighted and T2-weighted fluid-attenuated inversion recovery) and hemodynamic (BOLD and CBF-weighted arterial spin labeling) functional MRI during room air and hypercarbic gas administration. CBF changes in regions demonstrating negative BOLD reactivity were recorded, as well as clinical correlates including symptomatic hemisphere by infarct and lateralizing symptoms. Fifteen out of forty participants exhibited negative BOLD reactivity. Of these, a positive relationship was found between BOLD and CBF reactivity in unaffected (stenosis degree<50%) cortex. In negative BOLD cerebrovascular reactivity regions, three patients exhibited significant (P<0.01) reductions in CBF consistent with vascular steal; six exhibited increases in CBF; and the remaining exhibited no statistical change in CBF. Secondary findings were that negative BOLD reactivity correlated with symptomatic hemisphere by lateralizing clinical symptoms and prior infarcts(s). These data support the conclusion that negative hypercarbia-induced BOLD responses, frequently assigned to vascular steal, are heterogeneous in origin with possible contributions from autoregulation and/or metabolism.

    The aims of this study were to investigate concrete and abstract word definition ability (1) between patients with amnestic mild cognitive impairment (aMCI) and normal adults and (2) between the aMCI subtypes (i.e., amnestic single-domain MCI and amnestic multidomain MCI; asMCI and amMCI) and normal controls. The 68 patients with aMCI (29 asMCI and 39 amMCI) and 93 age- and education-matched normal adults performed word definition tasks composed of five concrete (e.g., train) and five abstract nouns (e.g., jealousy). Task performances were analyzed on total score, number of core meanings, and number of supplementary meanings. The results were as follows. First, the aMCI patients scored significantly poorer than the normal controls in only abstract word definition. Second, both subtypes of aMCI performed worse than the controls in only abstract word definition. In conclusion, a definition task of abstract rather than concrete concepts may provide richer information to show semantic impairment of aMCI.

    Objective Stroke and transient ischemic attacks are considered as clinical manifestations of atherosclerotic disease due to on-going vascular inflammation and finally atherothrombosis of the carotid arteries. MicroRNAs (miRNA/miR) are known to be involved in vascular inflammation and plaque destabilization. The aim of this study was to analyze the expression profile of selected miRNAs in endarterectomy specimen from carotid arteries that were taken from patients with asymptomatic and symptomatic atherosclerotic plaques. Methods and Results 11 miRNAs were selected and their expression was analyzed using real-time RT-PCR. Therefore, samples were divided into three different groups. On the one hand we investigated the expression patterns from patients in asymptomatic (n = 14) and symptomatic (n = 10) plaques; on the other hand we took samples from normal configurated internal mammary arteries (n = 15). Out of these 11 targets we identified some miRNAs, which were up- or down-regulated in either one of the two groups. Interestingly, the expression of two miRNAs was significantly different between asymptomatic and symptomatic samples, namely miR-21 (P<0.01) and miR-143 (P<0.05). Conclusion In the present study, we identified miRNA subtypes which showed different expression in endarterectomy specimen from patients with asymptomatic and symptomatic plaques, suggesting that these miRNAs correlated with advanced vascular inflammation and plaque stability. They may represent new therapeutic targets for vascular proliferative diseases such as atherosclerosis. PMID:27631489

    Pyuria is frequently present in patients who require bladder instrumentation. Using the hemocytometer chamber method, we prospectively studied the regression of pyuria in 29 spinal cord-injured (SCI) men with symptomatic urinary tract infection (UTI) who were grouped according to the method of bladder drainage: (a) Intermittent catheterization program (ICP; 10 patients); (b) Suprapubic tube (SPT; 10 patients); and (c) Indwelling foley catheters (IFC; 9 patients). All of the patients experienced relief of presenting symptoms within 3-4 days of receiving appropriate antibiotic therapy. The clinical response was associated with > or = 65% and > or = 87% reduction in the levels of pyuria at mid-therapy and after completion of antimicrobial therapy, respectively. Using a one-way analysis of variance, the group of patients who underwent ICP had significantly lower residual levels of pyuria at mid-therapy and after completion of therapy when compared to the other two groups (P < 0.05). The findings of relatively lower absolute levels of pyuria in the ICP group vs the SPT and IFC group of patients suggest that the response of pyuria to appropriate therapy for symptomatic UTI can be assessed better and earlier in patients who undergo ICP.

    Summary Background Global longitudinal peak strain (GLPS) quantifies left ventricle (LV) long-axis contractility. Early detection of LV systolic dysfunction is pivotal in diagnosis and treatment of patients with aortic stenosis (AS). This study was performed to assess LV longitudinal systolic function by GLPS derived from 2-dimensional speckle tracking imaging (2D-STI) in AS patients in comparison to standard echocardiographic parameters. Material/Methods Laboratory tests, standard echocardiography, tissue Doppler imaging (TDI) and 2D-STI examinations with GLPS calculation were performed in 49 consecutive patients with moderate to severe AS with LV ejection fraction ≥50% and 18 controls. Results While LVEF do not differentiate AS patients from controls, GLPS was significantly decreased in the AS group (−15.30±3.25% vs. −19.60±2.46% in controls, p<0.001). GLPS was significantly reduced in symptomatic AS patients as compared to the asymptomatic AS group [−15.5 (11.8–16.8) vs. −17.5 (14.7–18.9)%, p=0.02]. Conclusions In aortic stenosis patients, despite normal left ventricle ejection fraction, long-axis left ventricular function is impaired, which manifests in global longitudinal peak strain reduction. GLPS reveals that LV function impairment is more pronounced in symptomatic as compared to asymptomatic AS patients. Further studies are needed to determine the prognostic significance of early LV function impairment in aortic stenosis patients showed by GLPS. PMID:23197243

    Patients who undergo a Roux-en-Y gastric bypass (RYGB) procedure are at moderate risk for calcium and vitamin D deficiency. Those who subsequently undergo thyroid or parathyroid surgery are at high risk for developing severe symptomatic hypocalcemia if they are not monitored and adequately treated prophylactically. We describe the case of a morbidly obese 40-year-old man who had undergone RYGB surgery 6 months prior to the discovery of metastatic papillary thyroid carcinoma. He subsequently underwent total thyroidectomy with central and bilateral neck dissection. Following surgery, he developed severe symptomatic hypocalcemia, as his calcium level fell to a nadir of 6.0 mg/dl. He required aggressive oral and intravenous repletion therapy with calcium, vitamin D, and magnesium for 10 days before hospital discharge. Providers should institute careful preoperative screening, patient counseling, and prophylactic calcium and vitamin D therapy for all thyroid surgery patients who have previously undergone RYGB surgery to prevent the development of severe and life-threatening hypocalcemia. Only a few reports of patients have been published on the dangers of thyroid and parathyroid surgery in patients who have undergone bariatric surgery. We report a new case to add to the body of literature on this patient population. We also review calcium homeostasis and supplementation as they relate to this situation.

    Five hundred subjects with symptomatic limb joint osteoarthritis, who had been referred to a rheumatologist, were enrolled into a continuing study. They comprised 342 women (mean age 65.3) and 158 men (mean age 59.7), with a mean symptom duration of 15.4 years at entry. Only 31 patients (6%) had symptomatic osteoarthritis of one joint alone; however, in a further 205 (41%) the disease was limited to one site. One hundred and eighty two (36.4%) had two sites affected and 82 (16.4%) three or more sites of symptomatic osteoarthritis. Of 847 affected joints the most commonly involved were 349 (41.2%) knees, 254 (30%) hands, and 161 (19%) hips. Hip disease stood out as a separate entity, often occurring alone, and having a stronger male preponderance and different associations than osteoarthritis at other joint sites. Knee and hand disease were significantly associated in women. Obesity, hypertension, and Heberden's nodes were common. The number of sites affected, as well as the distribution, was strongly related to age as well as sex, suggesting that polyarticular osteoarthritis arises from slow acquisition of new joint sites in a non-random distribution. 'Generalised' osteoarthritis did not emerge as a distinct entity. PMID:1994877

    Metastatic prostate cancer continues to kill approximately 30,000 men per year. Since 2010, five new therapeutic agents have been Food and Drug Administration (FDA) approved to treat metastatic castration-resistant prostate cancer (mCRPC). With the increasing number of therapies available to clinicians, the most effective sequence in which to implement these treatments remains unknown. The presence or absence of symptoms (i.e., bony pain, visceral crisis) is a key parameter that informs the decision-making process regarding therapy. Treatment algorithms based on: 1) asymptomatic/minimal symptoms, 2) moderate symptoms or chemotherapy ineligible or 3) symptomatic disease need to be developed. PMID:25865849

    Objectives Assessment of dental pain severity is very challenging in dentistry. Previous studies have suggested that elevated salivary alpha amylase may contribute to increased physical stresses. There is a close association between salivary alpha amylase and plasma norepinephrine under stressful physical conditions. The aim of this study was to evaluate the relationship between pain severity and salivary alpha amylase levels in patients with symptomatic irreversible pulpitis. Materials and Methods Thirty-six patients (20 females and 16 males) with severe tooth pain due to symptomatic irreversible pulpitis were selected. The visual analogue scale (VAS) score was used to assess the pain severity in each patient. Unstimulated whole saliva was collected, and the level of alpha amylase activity was assessed by the spectrophotometric method. Statistical analysis was performed using SPSS 13. Results The level of alpha amylase was significantly increased in the saliva in association with pain severity assessed by VAS. The salivary alpha amylase was also elevated with increased age and in males. Conclusions There was a significant correlation between the VAS pain scale and salivary alpha amylase level, which indicates this biomarker may be a good index for the objective assessment of pain intensity.

    Dicer and Drosha are key enzymes in the miRNA-processing pathway which is altered in many human cancers. We analyzed Dicer and Drosha expression levels by quantitative PCR in 151 patients with monoclonal gammopathies: 102 symptomatic myeloma patients, 23 smoldering myelomas and 26 monoclonal gammopathy of undetermined significance. We found that Dicer expression values were significantly higher in monoclonal gammopathy of undetermined significance than in smoldering myelomas and symptomatic myeloma (mean ± SD, 0.84±0.36 vs. 0.60±0.23 and 0.62±0.51; P<0.01). Moreover, the median progression-free survival was significantly longer in symptomatic myeloma patients with high expression of Dicer (not reached vs. 23.6 months; P=0.02). By contrast, no differences in the expression of Drosha among these groups of patients were observed. Our data suggest that Dicer expression may play an important role in the progression and prognosis of monoclonal gammopathies.

    Introduction Intra-aortic counterpulsation balloon pumps (IABPs) have been widely used to augment hemodynamics in critically ill patients with cardiogenic shock and have recently been proposed as a management strategy for subarachnoid hemorrhage (SAH) patients with neurogenic stress cardiomyopathy (NSC). Prior case series have described the use of IABP as a means to manage cardiogenic shock in this patient population; however, we sought to describe our experience with IABP as a means to wean vasopressor requirement while augmenting hemodynamics and maintaining pressures at goal. Methods Five patients were identified from a single center, prospective, observational cohort study that received an IABP for the management of ischemia related to cerebral vasospasm in the setting of NSC. We evaluated all cases for efficacy of IABP in reducing vasopressor requirement, and complications. Results Vasopressor requirements were reduced by a mean of 50% (range 25–65%) following IABPs placement within 24–48 h. There were no significant complications from IABPs. Out of the five patients, the outcome in three cases was favorable (mRS≤1). Two patients suffered delayed cerebral ischemia (DCI), one patient passed away due to severe sepsis, and one patient was left with severe disability. Only one patient required anticoagulation and that was for a preexisting deep venous thrombosis. Conclusion The use of IABPs may be beneficial as an adjunctive therapy in SAH patients with concomitant symptomatic vasospasm and NSC. PMID:27403221

    Abstract Little is known about injury of the arcuate fasciculus (AF) in patients with mild traumatic brain injury (TBI). We investigated injury of the AF in the dominant hemisphere in patients with mild TBI, using diffusion tensor tractography (DTT). We recruited 25 patients with injury of the left AF among 64 right-handed consecutive patients with mild TBI and 20 normal control subjects. DTTs of the left AF were reconstructed, and fractional anisotropy (FA), apparent diffusion coefficient (ADC), and fiber number of the AF were measured. Among 64 consecutive patients, 25 (39%) patients showed injury of the left AF. The patient group showed lower FA value and fiber number with higher ADC value than the control group (P < 0.05). On K-WAB evaluation, aphasia quotient and language quotient were 95.9 ± 4.1 (range 85–100) and 95.0 ± 5.4 (range 80–100), respectively. However, 23 (92.0%) of 25 patients complained of language-related symptoms after TBI; paraphasia in 12 (48.0%) patients, deficits of comprehension in 4 (16.0%) patients, deficits of speech production in 1 (4.0%) patient, and >2 language symptoms in 6 (24.0%) patients. We found that a significant number (39%) of patients with mild TBI had injury of the AF in the dominant hemisphere and these patients had mild language deficit. These results suggest that DTT could provide useful information in detecting injury of the AF and evaluation of the AF using DTT would be necessary even in the case of a patient with mild TBI who complains of mild language deficit.

    Allium ampeloprasum subsp iranicum (Leek) has been traditionally used in antihemorrhoidal topical herbal formulations. This study aimed to evaluate its safety and efficacy in a pilot randomized controlled clinical trial. Twenty patients with symptomatic hemorrhoids were randomly allocated to receive the topical leek extract cream or standard antihemorrhoid cream for 3 weeks. The patients were evaluated before and after the intervention in terms of pain, defecation discomfort, bleeding severity, anal itching severity, and reported adverse events. A significant decrease was observed in the grade of bleeding severity and defecation discomfort in both the leek and antihemorrhoid cream groups after the intervention, while no significant change was observed in pain scores. There was no significant difference between the leek and antihemorrhoid cream groups with regard to mean changes in outcome measures. This pilot study showed that the topical use of leek cream can be as effective as a standard antihemorrhoid cream.

    "Delayed or back up" antibiotic prescriptions and "symptomatic" treatment may help to reduce inappropriate antibiotic prescribing for Urinary Tract Infections (UTI) in the future. However, more research needs to be conducted in this area before these strategies can be readily promoted in practice. This study explores General Practitioner (GP) and patient attitudes and experiences regarding the use of delayed or back-up antibiotic and symptomatic treatment for UTI. Qualitative face to face interviews with General Practitioners (n = 7) from one urban and one rural practice and telephone interviews with UTI patients (n = 14) from a rural practice were undertaken. Interviews were analysed using framework analysis. GPs believe that antibiotics are necessary when treating UTI. There was little consensus amongst GPs regarding the role of delayed prescribing or symptomatic treatment for UTI. Delayed prescribing may be considered for patients with low grade symptoms and a negative dipstick test. Patients had limited experience of delayed prescribing for UTI. Half indicated they would be satisfied with a delayed prescription the other half would question it. A fear of missing a serious illness was a significant barrier to symptomatic treatment for both GP and patient. The findings of this research provide insight into antibiotic prescribing practices in general practice. It also highlights the need for further empirical research into the effectiveness of alternative treatment strategies such as symptomatic treatment of UTI before such strategies can be readily adopted in practice.

    Purpose To assess hemoglobin (Hb) outcomes and fatigue-related quality-of-life (QoL) (electronic assessment) in patients with solid tumors and symptomatic chemotherapy-induced anemia receiving cytotoxic chemotherapy and darbepoetin alfa (DA) or another erythropoiesis-stimulating agent according to European indication. Methods eAQUA was a Phase IV prospective observational study. The primary outcome (assessed in the primary analysis set [PAS]: patients receiving one or more DA dose who had baseline and week 9 assessments for Hb and QoL) was the proportion of patients receiving DA having both Hb increases ≥1 g/dL and improved QoL between baseline and week 9. Functional Assessment of Cancer Therapy-Fatigue (FACT-F) subscale scores were anchored to fatigue visual analog scale scores to determine the minimally important difference for improved QoL. Overall data/data over time are reported for the full analysis set (patients receiving one or more erythropoiesis-stimulating agent dose, n=1,158); week 9 data (ie, data relating to the primary and secondary outcomes) are reported for the PAS (n=510). Baseline and safety data are included for both the full analysis set and PAS. Results In the PAS, 69% of patients had stage IV disease and 96% were fatigued. The minimally important difference in FACT-F change score for QoL improvement was 3.5. From baseline to week 9, 32% (95% confidence interval: 28%–36%) of patients had both improved QoL and an Hb increase ≥1 g/dL; proportions were similar across the most common tumor types. At week 9, 49% and 58% of patients had improved QoL or Hb increases ≥1 g/dL, respectively; 70% and 76% had QoL or Hb improvements between baseline and study end, respectively. In the PAS, 16% of patients required transfusions and 32% required iron supplementation. Few patients (<1%) reported adverse drug reactions. Conclusion In this study, patients with solid tumors receiving DA per European indication for symptomatic chemotherapy-induced anemia

    Background Ulcerative colitis (UC) impairs the health-related quality of life (HRQOL). The difference in HRQOL between patients with mild and moderately active UC is not well-defined. Few studies have been conducted to explore the factors that influence HRQOL in Chinese patients. Our study aims were to (1) compare HRQOL of mildly active UC patients with moderate patients; (2) explore the factors that influence HRQOL in Chinese patients with UC; and (3) analyze demographic and disease characteristics of UC in China. Methods A total of 110 mild and 114 moderate patients with UC were enrolled. The demographic and disease characteristics were recorded. HRQOL was measured by the Chinese version of the inflammatory bowel disease questionnaire (IBDQ) between mild and moderate patients, male and female patients, and different disease distributions. Stepwise regression analysis was used to assess factors influencing the IBDQ score. Results Patients with moderate UC had significantly lower IBDQ total scores compared to patients with mild UC (P=0.001). The IBDQ total score had a negative correlation with the Mayo score (r=–0.263, P<0.001). Stepwise regression analysis showed that the disease activity index and gender had an influence on the IBDQ total score (P<0.05). The female patients had a lower score than the male patients (P<0.05), especially in the emotional function domain (P=0.002). Different disease distributions were not statistically significant in the IBDQ total score (P=0.183). Conclusions UC has a negative influence on HRQOL. HRQOL in patients with moderate UC was lower than HRQOL in patients with mild UC, as measured by the IBDQ. UC disease activity has a negative correlation with HRQOL. Gender and the disease activity index are important factors involved in the impairment of HRQOL in Chinese patients with UC. Chinese females may benefit from increased psychological care as part of UC therapy. PMID:25915777

    PURPOSE We aimed to investigate the safety and effectiveness of intracranial stenting in a population with severe (≥70%) symptomatic intracranial internal carotid artery (ICA) atherosclerotic stenosis. METHODS Fifty-eight patients with severe intracranial ICA atherosclerotic stenosis were prospectively enrolled. The baseline data, cerebral angiography, success rate, perioperative complications, clinical and imaging follow-up were prospectively analyzed. RESULTS All patients had successful intracranial stenting (100%), and the mean degree of stenosis was improved from 84.3%±7.5% to 23.5%±5.1% after the stent procedure. During the 30-day perioperative period, only one patient (1.7%) had ischemic stroke. Seven patients (12.1%) had headache and dysphoria. Thirty-six patients (62.1%) had clinical follow-up for 6–68 months after stenting. Five female patients (13.9%) had ipsilateral stroke including one death, but no disabling stroke, while three other patients (8.3%) had ipsilateral temporary ischemic attack (TIA). The recurrent stroke rate was higher in patients presenting with stroke (4/17, 23.5%) than in patients presenting with TIA (1/19, 5.3%), with no statistical significance (P = 0.33). Thirteen patients (22.4%) had imaging follow-up of 5–12 months following stenting, five of whom (38.5%) had in-stent restenosis. CONCLUSION Intracranial stenting for patients with intracranial ICA atherosclerotic stenosis has a low perioperative stroke rate and decent outcome on long-term follow-up, despite a relatively high in-stent restenosis rate.

    Purpose The purpose of this study was to analyze the safety and efficacy of intervention in patients with symptomatic Tarlov cysts by percutaneous, CT-guided two-needle cyst aspiration and fibrin sealant injection. Materials and Methods This study was designed to assess outcomes in patients who underwent CT-guided aspiration and injection of one or more sacral Tarlov cysts at Johns Hopkins Hospital between the years of 2003 and 2013. In all, 289 cysts were treated in 213 consecutive patients. All of these patients were followed for at least six months; 90% were followed for one year and 83% were followed for three to six years. The aspiration-injection procedure employed two needles and was carried out with local anesthesia and intravenous analgesia. In the fibrin injection stage of the procedure, a commercially available fibrin sealant was injected into the cyst through the deep needle (Tisseel VH; Baxter Healthcare, Westlake Village, California). Results One year post-procedure, excellent results had been obtained in 104 patients (54.2% of patients followed) and good or satisfactory results had been obtained in 53 patients (27.6%). Thus, 157 patients (81.8%) in all were initially satisfied with the outcome of treatment. At three to six years post-procedure, 74.0% of patients followed were satisfied with treatment. There were no significant complications. Conclusions The aspiration-injection technique described herein constitutes a safe and efficacious treatment option that holds promise for relieving cyst-related symptoms in many patients with very small risk.

    Background Chlamydia trachomatis infections are the most prevalent sexually transmitted bacterial infections in the world. There is scarce data available referring to the distribution of C. trachomatis genotypes in Argentina. The aim of this study was to identify the genotypes of C. trachomatis circulating in the metropolitan area of Buenos Aires (Argentina) associated with ophthalmia neonatorum and genital infections. Findings From 2001 to 2006, 199 positive samples for C. trachomatis infection from symptomatic adult patients and neonates with ophthalmia neonatorum from two public hospitals were studied. C. trachomatis genotypes were determined by PCR-RFLP of an ompA fragment. Genotype E was the most prevalent regardless of the sample origin (46.3% 57/123 in adults and 72.4% 55/76 in neonates), followed by genotype D (19.5% 24/123) and F (14.6% 18/123) in adults, and G (9.2% 7/76) and D (7.9% 6/76) in neonates. We detected a significantly higher frequency of genotype E (p < 0.001, OR = 3.03 (1.57symptomatic adult patients in Buenos Aires, Argentina, in which genotypes E, D and F were the predominant ones.

    Introduction It is generally accepted that achieving complete anaesthesia with an Inferior Alveolar Nerve Block (IANB) in mandibular molars with symptomatic irreversible pulpitis is more challenging than for other teeth. Therefore, administration of Non-Steroidal Anti-Inflammatory Agents (NSAIDs) 1 hour prior to anaesthetic administration has been proposed as a means to increase the efficacy of the IANB in such patients. Aim The purpose of this prospective, double-blind, randomized clinical trial was to determine the effect of administration of oral premedication with ketorolac (KETO) and diclofenac potassium (DP) on the efficacy of IANB in patients with irreversible pulpitis. Materials and Methods One hundred and fifty patients with irreversible pulpitis were evaluated preoperatively for pain using Heft Parker visual analogue scale, after which they were randomly divided into three groups. The subjects received identical tablets of ketorolac, diclofenac pottasium or cellulose powder (placebo), 1 hour prior to administration of IANB with 2% lidocaine containing 1:200 000 epinephrine. Lip numbness as well as positive and negative responses to cold test were ascertained. Additionally pain score of each patient was recorded during cavity preparation and root canal instrumentation. Success was defined as the absence of pain or mild pain based on the visual analog scale readings. The data was analysed using One-Way Anova, Post-Hoc Tukey pair wise, Paired T – Test and chi-square test. Trial Registery Number is 4722/2015 for this clinical trial study. Results There were no significant differences with respect to age (p =0.098), gender (p = 0.801) and pre-VAS score (DP-KETO p=0.645, PLAC-KETO p =0.964, PLAC-DP p = 0.801) between the three groups. All patients had subjective lip anaesthesia with the IAN blocks. Patients of all the three groups reported a significant decrease in active pain after local anaesthesia (p< 0.05). The post injection VAS Score was least in group

    The studies reported here addressed 20 patients aged 60-69 years whose clinical picture combined the manifestations of mild dementia with those of mild depression and anxiety. Patients were treated with Coaxil (tianeptine) for 60 days at a dose of 37.5 mg/day. Patients were assessed by clinical-psychological investigations with addition of the Hamilton scales and neuropsychological testing by the Luriya method. Coaxil was found to be highly effective in relation to all psychopathological components. Recommendations for the use of Coaxil in elderly patients with cognitive and depressive-anxiety disorders are formulated.

    Polyhydramnios, megalencephaly, and symptomatic epilepsy syndrome (PMSE) is an ultra rare neurodevelopmental disorder characterized by severe, infantile-onset intractable epilepsy, neurocognitive delay, macrocephaly, and craniofacial dysmorphism. The molecular diagnosis of this condition has thus far only been made in 16 Old Order Mennonite patients carrying a homozygous 7 kb founder deletion of exons 9-13 of STRADA. We performed clinical whole exome sequencing (WES) on a 4-year-old Indian male with global developmental delay, history of failure to thrive, infantile spasms, repetitive behaviors, hypotonia, low muscle mass, marked joint laxity, and dysmorphic facial features including tall forehead, long face, arched eyebrows, small chin, wide mouth, and tented upper lip. A homozygous single nucleotide duplication, c.842dupA (p.D281fs), in exon 10 of STRADA was identified. Sanger sequencing confirmed the mutation in the individual and identified both parents as carriers. In light of the molecular discoveries, the patient's clinical phenotype was considered to be a good fit for PMSE. We identified for the first time a homozygous point mutation in STRADA causing PMSE. Additional bi-allelic mutations related to PMSE thus far have not been observed in Baylor ∼6,000 consecutive clinical WES cases, supporting the rarity of this disorder. Our findings may have treatment implications for the patient since previous studies have shown rapamycin as a potential therapeutic agent for the seizures and cognitive problems in PMSE patients. © 2016 Wiley Periodicals, Inc.

    Background and Purpose Imaging studies of traumatic brain injury demonstrate that the cerebellum is often affected. We aim to examine fractional anisotropy alteration in acute-phase mild traumatic brain injury patients in cerebellum-related white matter tracts. Materials and Methods This prospective study included 47 mild traumatic brain injury patients in the acute stage and 37 controls. MR imaging and neurocognitive tests were performed in patients within 7 days of injury. White matter integrity was examined by using diffusion tensor imaging. We used three approaches, tract-based spatial statistics, graphical-model-based multivariate analysis, and region-of-interest analysis, to detect altered cerebellar white matter integrity in mild traumatic brain injury patients. Results Results from three analysis methods were in accordance with each other, and suggested fractional anisotropy in the middle cerebellar peduncle and the pontine crossing tract was changed in the acute-phase mild traumatic brain injury patients, relative to controls (adjusted p-value < 0.05). Higher fractional anisotropy in the middle cerebellar peduncle was associated with worse performance in the fluid cognition composite (r = -0.289, p-value = 0.037). Conclusion Altered cerebellar fractional anisotropy in acute-phase mild traumatic brain injury patients is localized in specific regions and statistically associated with cognitive deficits detectable on neurocognitive testing.

    SUMMARY The prevalence of Helicobacter pylori infection in Indonesia is controversial. We examined the H. pylori infection rate in 78 patients in a hospital in Surabaya using five different tests, including culture, histology, immunohistochemistry, rapid urease test, and urine antibody test. Furthermore, we analysed virulence factors in H. pylori strains from Indonesia. The H. pylori infection rate was only 11.5% in all patients studied, and 2.3% of Javanese patients and 18.0% of Chinese patients were infected (P = 0.01). Although severe gastritis was not observed, activity and inflammation were significantly higher in patients positive for H. pylori than in patients negative for H. pylori. Among genotypes identified from five isolated strains, cagA was found in four; two were vacA s1m1. All cagA-positive strains were oipA 'on' and iceA1 positive. We confirmed both a low H. pylori infection rate and a low prevalence of precancerous lesions in dyspeptic patients in a Surabaya hospital, which may contribute to the low incidence of gastric cancer in Indonesia.

  18. [Symptomatic treatment in patients with dementia: light, but not melatonin, is probably worthwhile].

    PubMed

    2008-10-25

    A recent study in the JAMA described the effects of long-term daily treatment with whole-day bright light in elderly patients with dementia, with or without the addition of melatonin (2.5 mg daily), on cognition, mood, behavioural symptoms, activities of daily living and sleep. It was concluded that light has a modest benefit in improving some cognitive and non-cognitive symptoms of dementia. The effects of melatonin were negligible. Despite the small effects found of this study, the outcomes can be used in clinical practice since other small studies also show a trend towards positive effects of bright light in dementia patients. Since current pharmacotherapy for behavioural problems in dementia has very modest effects at the risk of serious adverse effects, non-pharmacological interventions must be encouraged. Increasing light intensity in the living rooms of patients with dementia is an easy and cheap intervention with possible positive effects on at least some patients.

    Background: With increasing frequency, platelet-rich plasma (PRP) preparations have been used to treat cartilage lesions to regenerate tissue homeostasis and retard the progression of knee osteoarthritis (OA). Purpose: To determine the effectiveness of intra-articular PRP injections in active patients with knee OA and to evaluate clinical outcomes in patients with and without previous surgical treatment for cartilage lesions. Study Design: Case series. Materials and Methods: Fifty patients with knee OA were followed for a minimum of 12 months. All were treated with 2 intra-articular injections of autologous PRP. Twenty-five patients had undergone a previous operative intervention for cartilage lesions, whereas 25 had not. Operated patients had undergone either cartilage shaving or microfracture. Multiple evaluative scores were collected at pretreatment and at 6 and 12 months posttreatment. The required sample of patients was determined beforehand by using statistical power analysis; International Knee Documentation Committee (subjective) score was defined as the primary parameter. A P value of less than 0.05 was considered statistically significant. General linear model–repeated measure test evaluated within-time improvement for each variable for all patients. Post hoc test with Bonferroni adjustment for multiple comparisons was performed to investigate the significance in improvement within time evaluations for each variable for the total sample. The differences in improvement between operated and nonoperated patients were also investigated, as were those between sexes. Results: All patients showed significant improvement in all scores at 6 and 12 months (P < 0.01) and returned to previous activities. No significant difference in improvement was found between the evaluated subgroups (P < 0.01). Conclusions: The PRP treatment showed positive effects in patients with knee OA. Operated and nonoperated patients showed significant improvement by means of diminishing

    Working Memory and executive functioning deficits are core characteristics of patients suffering from schizophrenia. Electrophysiological research indicates that altered patterns of neural oscillatory mechanisms underpinning executive functioning are associated with the psychiatric disorder. Such brain oscillatory changes have been found in local amplitude differences at gamma and theta frequencies in task-specific cortical areas. Moreover, interregional interactions are also disrupted as signified by decreased phase coherence of fronto-posterior theta activity in schizophrenia patients. However, schizophrenia is not a one-dimensional psychiatric disorder but has various forms and expressions. A common distinction is between positive and negative symptomatology but most patients have both negative and positive symptoms to some extent. Here, we examined three groups—healthy controls, predominantly negative, and predominantly positive symptomatic schizophrenia patients—when performing a working memory task with increasing cognitive demand and increasing need for executive control. We analyzed brain oscillatory activity in the three groups separately and investigated how predominant symptomatology might explain differences in brain oscillatory patterns. Our results indicate that differences in task specific fronto-posterior network activity (i.e., executive control network) expressed by interregional phase synchronization are able to account for working memory dysfunctions between groups. Local changes in the theta and gamma frequency range also show differences between patients and healthy controls, and more importantly, between the two patient groups. We conclude that differences in oscillatory brain activation patterns related to executive processing can be an indicator for positive and negative symptomatology in schizophrenia. Furthermore, changes in cognitive and especially executive functioning in patients are expressed by alterations in a task

    Differential diagnosis of asymptomatic bacteriuria (ASB) and urinary tract infection (UTI) is based on the presence of diverse symptoms, including fever (≥38.5°C), rigors, malaise, lethargy, flank pain, hematuria, suprapubic discomfort, dysuria, and urgent or frequent urination. There is consensus in the medical community that ASB warrants antibiotic treatment only for patients undergoing urological procedures that lead to mucosal bleeding, catheterized individuals whose ASB persists for more than 48 h after catheter removal, and pregnant women. Pyuria is associated with UTI and implicates host immune responses via release of antibacterial effectors and phagocytosis of pathogens by neutrophils. Such responses are not sufficiently described for ASB. Metaproteomic methods were used here to identify the pathogens and evaluate molecular evidence of distinct immune responses in cases of ASB compared to UTI in elderly patients who were hospitalized upon injury. Neutrophil-driven inflammatory responses to invading bacteria were not discernible in most patients diagnosed with ASB compared to those with UTI. In contrast, proteomic urine analysis for trauma patients with no evidence of bacteriuria, including those who suffered mucosal injuries via urethral catheterization, rarely showed evidence of neutrophil infiltration. The same enzymes contributing to the synthesis of leukotrienes LTB4 and LTC4, mediators of inflammation and pain, were found in the UTI and ASB cohorts. These data support the notion that the pathways mediating inflammation and pain in most elderly patients with ASB are not quantitatively different from those seen in most elderly patients with UTI and warrant larger clinical studies to assess whether a common antibiotic treatment strategy for elderly ASB and UTI patients is justified.

    Background: This experimental study was designed to determine if Helicobacter spp. contribute to benign gallbladder disease using polymerase chain reaction (PCR) methods. Methods: Patients with benign gallbladder disease scheduled for elective cholecystectomy at New York University Langone Medical Center were recruited from February to May 2008. Bile, gallbladder tissue and gallstones were collected. DNA was isolated from these specimens and amplified via PCR using C97F and C98R primers specific for Helicobacter spp. Appropriate positive and negative controls were used. Products were analysed with agarose gel electrophoresis, sequenced and results aligned using sequencher. Plasma was collected for detection of anti-Helicobacter pylori antibodies via enzyme-linked immunosorbent assay. Results: Of 36 patients, 12 patients' bile and/or tissue were positive for Helicobacter spp. by PCR. Species were most homologous with H. pylori, although other Helicobacter spp. were suggested. Six of 12 patients demonstrated anti-Helicobacter antibodies in plasma, suggesting that the remaining six might have demonstrated other species besides H. pylori. Four of six plasma samples with anti-Helicobacter antibodies were anti-CagA (cytotoxin associated gene) negative. Discussion: Helicobacter spp. can be detected in bile and gallbladder tissue of patients with benign gallbladder disease. The contribution of these bacteria to the pathophysiology of gallbladder disease and gallstone formation requires further study. PMID:20495657

    Wilson's disease is an inherited disease of copper metabolism leading to the toxic accumulation of copper, primarily in the liver and brain. Although the literature shows successful outcomes after proper treatment, pregnant patients with Wilson's disease still need close monitoring and management. Here, we report the case of a successful pregnancy in a Korean woman with Wilson's disease. A 33-year-old primigravid patient with Wilson's disease visited our antenatal clinic. Of her own volition, she had stopped her medication 2 years earlier. Oral zinc oxide therapy was started, and she was closely monitored throughout her pregnancy. She delivered a healthy female infant weighing 3.13 kg through a cesarean section. After delivery, the clinical course of both the mother and the baby were uneventful. We review crucial points in the treatment and the management dilemmas raised by the patient. PMID:26430668

    Wilson's disease (WD) is caused by excess of copper that leads to accumulation of copper mainly in the liver, brain and needs life-long decoppering therapy. However, overtreatment with anti-copper agents may lead to copper deficiency which may cause neurological and hematological symptoms. Copper is an important cofactor for many enzymes. This report describes three WD patients with diagnosed copper deficiency during zinc sulphate (ZS) treatment. After 5-16 years of therapy all patients developed leucopenia. Spinal cord injury was manifested in two of the patients. One of them also presented myopathy. In conclusion, copper deficiency may occur in different time after treatment onset, therefore regular copper metabolism and hematological monitoring is necessary.

  8. Gastrointestinal symptoms after pelvic radiotherapy: a new understanding to improve management of symptomatic patients.

    PubMed

    Andreyev, Jervoise

    2007-11-01

    Gastrointestinal symptoms after pelvic radiotherapy, which affect quality of life, are substantially more common than generally recognised and are frequently poorly managed. These symptoms develop because radiation can induce change in one or more specific physiological functions in widely separated parts of the gastrointestinal tract that lie in the path of the radiotherapy beam. Radiation-induced changes are not confined by normal anatomical boundaries. Furthermore, pre-existing subclinical disease might be destabilised because of minor gastrointestinal changes induced by radiotherapy. New diseases might manifest after radiotherapy and be confused with symptoms induced by radiotherapy. Different functional deficits might cause the same symptoms. Many patients have more than one cause for their symptoms, which sometimes need very different treatments. Simple diagnostic tests that are used in other contexts, if applied appropriately to patients with new gastrointestinal symptoms after radiotherapy, can identify the underlying causes of new-onset symptoms. Starting treatment without knowing the cause of the symptom is commonly ineffective because prediction of the combination of treatments needed is difficult. Evidence suggests that many patients have unusual but highly treatable malfunctions of gastrointestinal physiology, which if correctly diagnosed may enable a patient with difficult symptoms to be helped.

    We identified 5 patients with subnormal erythrocyte lactate transport plus symptoms and signs of muscle injury on exercise and heat exposure. All had transport rates below the 95% envelope for normals. Three cases had rates 40-50% of mean normal. One was found to have a missense mutation in monocarboxylate transporter 1 (MCT1), the gene for the red cell lactate transporter (also expressed in skeletal muscle), at a conserved site, which was not mutated in a cohort of 90 normal humans. The other 2 cases had a different missense mutation (at a nonconserved site), which was also not mutated in the normal cohort. All 3 patients were heterozygotes. We presume that these mutations are responsible for their subnormal lactate transport, and hence their muscle injury under environmental stress; homozygous patients should be more seriously compromised. The other 2 cases had lactate transport rates 60-65% of mean normal, and their MCT1 revealed a third mutation, which proved to be a common polymorphism in the normal cohort. These 2 patients may be physiologic outliers in lactate transport, with their muscle damage arising from some other genetic defect.

    Preterm delivery is the leading cause of neonatal mortality and morbidity. The rate of preterm births has been estimated to be about 15 million, which accounts for 11.1% of all live births worldwide. The purpose of this study was to evaluate the cervico-vaginal (CVF) cytokine IL-6 and fetal fibronectin (fFN) status as predictors of preterm delivery in patients with symptoms of preterm labor. Patients with symptoms suggestive of preterm labor were recruited from September 2013 to March 2014. Vaginal swabs were taken for fetal fibronectin test (fFN) and CVF IL-6. Antibiotics, steroids and tocolytics were administered, where appropriate. The outcome was measured by the occurrence of preterm delivery within 14 days from the day of hospital admission. Cut-off value of 1305 pg/mL for the concentration of IL-6 in the CVF was the best predictor of preterm delivery, with the sensitivity of 69.4% and specificity of 68.2%. Patients with positive fFN test had the OR of 6.429 (95%CI 1.991-20.758) to deliver prematurely. The multivariate analysis of combined fFN and CVF IL-6 tests resulted in risk of 86.7% to deliver prematurely, if both tests were positive. The combination of both tests performed better than the individual tests and decreased the false positive rate, which in turn reduced the chances for inappropriate patient treatment, bringing down the costs.

    A variety of approaches have been used to alleviate symptoms in postural tachycardia syndrome (POTS). Drugs reported to be of benefit include midodrine, propranolol, clonidine, and phenobarbital. Other measures used include volume expansion and physical countermaneuvers. These treatments may influence pathophysiologic mechanisms of POTS such as alpha-receptor dysfunction, beta-receptor supersensitivity, venous pooling, and brainstem center dysfunction. The authors prospectively studied hemodynamic indices and symptom scores in patients with POTS who were acutely treated with a variety of interventions. Twenty-one subjects who met the criteria for POTS were studied (20 women, 1 man; mean age, 28.7 +/- 6.8 y; age range, 14-39 y). Patients were studied with a 5-minute head-up tilt protocol, ECG monitoring, and noninvasive beat-to-beat blood pressure monitoring, all before and after the administration of an intervention (intravenous saline, midodrine, propranolol, clonidine, or phenobarbital). The hemodynamic indices studied were heart rate (ECG) and systolic, mean, and diastolic blood pressure. Patients used a balanced verbal scale to record any change in their symptoms between the tilts. Symptom scores improved significantly after the patients received midodrine and saline. Midodrine and propranolol reduced the resting heart rate response to tilt (p <0.005) and the immediate and 5-minute heart rate responses to tilt (p <0.002). Clonidine accentuated the immediate decrease in blood pressure on tilt up (p <0.05). It was concluded that midodrine and intravenous saline are effective in decreasing symptoms on tilt in patients with POTS when given acutely. Effects of treatments on heart rate and blood pressure responses generally reflected the known pharmacologic mechanisms of the agents.

    Clinical trials of migraine therapy often require treatment when migraine pain intensity is moderate or severe, but many physicians find this practice artificial and patients often prefer to treat while pain is mild. This randomized, placebo-controlled study assessed the efficacy of zolmitriptan 2.5 mg in treating migraine while pain is mild, in patients who typically experience migraine attacks that are initially mild, but progress to moderate or severe. The intent-to-treat population comprised 280 patients (138 zolmitriptan; 148 placebo), with mean MIDAS grades of 29.6 (zolmitriptan) and 27.6 (placebo). Zolmitriptan 2.5 mg provided a significantly higher pain-free rate at 2 h (43.4% vs. 18.4% placebo; P < 0.0001). Significantly fewer zolmitriptan patients reported progression of headache pain to moderate or severe intensity 2 h postdose (53.7% vs. 70.4% placebo; P < 0.01), or required further medication within 24 h (46.4% vs. 71.1% placebo; P < 0.0001). The efficacy of zolmitriptan was more pronounced in patients treating during the first 15 min following pain onset. Adverse events were reported in 31.2% of patients treated with zolmitriptan (vs. 11.3% for placebo), and the incidence was lower in patients who treated early after attack onset. Zolmitriptan provides high efficacy when treating migraine while pain is mild, with the clinical benefits being more pronounced when treating early after migraine onset.

    At the Regional Hospital of Temuco, 670 adult and children patients, with intestinal complaints, were studied to determine the prevalence of infection by enteroparasites or commensals in a general way, and by Blastocystis hominis in a particular attempt. A coproparasitological study was carried out using a modified Telemann method. Infection by parasites and/or commensals was demonstrated in 446 (66.6%) patients. The most frequent agent was B. hominis (35.8%) followed by Giardia intestinalis (22.5%) among the protozoa. The frequencies of helminths and commensals were 7.7 and 42.5% respectively. The endemic characteristics of intestinal infections by parasites was ratified and the prevalence of infection by B. hominis was proved to be higher in comparison to other zones of the country.

She is known to have submucosal uterine fibroid (SMUF). The patient reported abdominal pain and sudden onset of 'miscarriage-like' HMB with clots 2 days ago. On speculum examination there was a smooth round-shaped mass lying over the external cervical os. On bimanual examination PV, a round-shaped smooth mass of a walnut's size was palpable in the upper third of the vagina. Subsequent ultrasound imaging revealed an SMUF prolapsed into the vagina. Further surgical treatment was undertaken. Histology showed a fibroid (leiomyoma) with no evidence of malignancy.

    Background SDF1 and its cognate receptors CXCR4 and CXCR7 are involved in myocardial repair and are associated with outcome in cardiovascular patients. Hence, we aimed to investigate clinically significant SDF1 SNPs for their prognostic impact in patients with cardiovascular disease. Methods and Results Genotyping for selected SDF1 variants (rs1065297, rs2839693, rs1801157, rs266087, rs266085 and rs266089 was performed in patients (n = 872) who underwent percutaneous coronary intervention. Carriers of variant rs2839693 and rs266089 showed significantly higher cumulative event-free survival compared with non-carriers. All other polymorphisms had no relevant influence on outcome. Multivariate Cox regression analysis showed a significant correlation of these SNPs with cardiovascular outcome after inclusion of clinical and prognostic relevant variables (hazard ratio (HR) 0.51 (95% CI 0.30–0.88), p = 0.015 and [HR 0.51 (95% CI 0.30–0.88), p = 0.016, respectively). In addition, multivariate Cox regression with SDF1 haplotypes revealed a significantly reduced risk for the haplotype carrying the minor alleles of rs2839693 and rs266089 (HR 0.47 (95% CI 0.27–0.84), p = 0.011). Conclusion Distinct SDF1 polymorphisms are associated with improved cardiovascular prognosis in CAD patients. Further studies are warranted to validate these results and to better describe the endogenous regeneration potential in carriers of these SNPs. Targeted, genotype guided therapeutic approaches to foster myocardial regeneration and thus cardiovascular prognosis should be evaluated in future. PMID:27607427

    Background Atherosclerosis is a major cause of cerebrovascular disease. Matrix metalloproteinases (MMPs) play an important role in matrix degradation within the atherosclerotic lesion leading to plaque destabilization and ischemic stroke. We hypothesized that MMP-7 could be involved in this process. Methods Plasma levels of MMP-7 were measured in 182 consecutive patients with moderate (50–69%) or severe (≥70%) internal carotid artery stenosis, and in 23 healthy controls. The mRNA levels of MMP-7 were measured in atherosclerotic carotid plaques with different symptomatology, and based on its localization to macrophages, the in vitro regulation of MMP-7 in primary monocytes was examined. Results Our major findings were (i) Patients with carotid atherosclerosis had markedly increased plasma levels of MMP-7 compared to healthy controls, with particularly high levels in patients with recent symptoms (i.e., within the last 2 months). (ii) A similar pattern was found within carotid plaques with markedly higher mRNA levels of MMP-7 than in non-atherosclerotic vessels. Particularly high protein levels of MMP-7 levels were found in those with the most recent symptoms. (iii) Immunhistochemistry showed that MMP-7 was localized to macrophages, and in vitro studies in primary monocytes showed that the inflammatory cytokine tumor necrosis factor-α in combination with hypoxia and oxidized LDL markedly increased MMP-7 expression. (iv) During the follow-up of patients with carotid atherosclerosis, high plasma levels of MMP-7 were independently associated with total mortality. Conclusion Our findings suggest that MMP-7 could contribute to plaque instability in carotid atherosclerosis, potentially involving macrophage-related mechanisms. PMID:24400123

    Background New approaches to assess outcome in schizophrenia include multidimensional measures such as remission, cognition, psychosocial functioning, and quality of life. Clinical and psychosocial measures have been recently introduced to assess functional outcome. Objective The study presented here was designed to examine the rates of symptomatic remission, psychosocial remission, global functioning, and clinical global impressions in a sample of schizophrenia outpatients in order to assess functional remission and to identify predictive factors for functional remission. Methods A total of 168 consecutive Mexican outpatients receiving pharmacological treatment at the National Institute of Psychiatry in Mexico City were enrolled in a cross-sectional study. Symptomatic remission was assessed according to the definition and criteria proposed by the Remission in Schizophrenia Working Group using the Positive and Negative Symptom Scale. Psychosocial remission was assessed according to Barak criteria using the Psychosocial Remission in Schizophrenia scale. Functioning was measured with the Global Assessment of Functioning, and clinical outcome with the Clinical Global Impressions (CGI) Scale. Results Findings showed that 45.2% of patients fulfilled the symptomatic remission criteria, 32.1% achieved psychosocial remission, and 53% reported adequate functioning. However, the combination of these three outcome criteria – symptomatic, psychosocial remission, and functioning – indicated that 14.9% of the patients achieved our predefined functional remission outcome. The logistic regression model included five predictive variables for functional remission: (1) being employed, (2) use of atypical antipsychotics, (3) lower number of medications, (4) lower negative symptom severity, and (5) lower excitement symptom severity. Conclusion The study demonstrated that symptomatic remission, psychosocial remission, and functioning could be achievable goals for a considerable

    Cervicogenic headache is a little-known clinical condition whose true importance has only recently been recognized. A number of causes may lie at the basis of the onset of headache (symptomatic cervicogenic headache). However, despite exhaustive attempts, sometimes it is not possible to identify a clear cause responsible for the onset of the syndrome (primitive cervicogenic headache). The genesis of symptomatic cervicogenic headaches sometimes may be easy to identify as a result of a close, pre-existing, cause-effect relationship (i.e. trauma). On other occasions it may be much more laborious to pinpoint the pathology responsible for headache (some cranio-cervical anomalies, etc.). Clinically, it is necessary to perform a thorough preliminary clinical and anamnestic evaluation which can orient subsequent investigations to achieve a diagnosis in the least time possible with the minimum discomfort to the patient and his relatives, not to mention lower costs for society.

    Symptomatic flatfoot is a prevalent disorder. We undertook a review of 50 feet in 39 patients with flexible flatfoot treated between August 2000 and January 2008 in order to evaluate the modified Kidner-Cobb procedure. Overall clinical results were rated as good in 48 (96%) feet and fair in 2 (4%) feet, and there were no poor results. Average follow-up was 4.6 years, and total recovery time was 5.7 months in older patients and 3.7 months in children. Manual muscle-strength testing revealed no difference in tibialis anterior strength between the operated and contralateral extremity. All patients visually demonstrated postoperative elevation of the medial longitudinal arch height. Complications included 2 feet with wound dehiscence and 1 foot with fractured hardware. The results of this review indicate that the modified Kidner-Cobb procedure is a useful treatment option for patients with symptomatic flexible flatfoot with posterior tibial tendon dysfunction stage 2.

    The most widely performed test for patients suspected of having carotid atherosclerosis is Doppler ultrasound (DUS). Unfortunately, limitations in sensitivity and specificity prevent DUS from being the sole diagnostic tool. Novel DUS velocity-derived parameters, such as turbulence intensity (TI), may provide enhanced hemodynamic information within the carotid artery, increasing diagnostic accuracy. In this study, we evaluate a new technique for recording, storing and analyzing DUS in a clinical environment, and determine the correlation between TI and conventional DUS measurements. We have recruited 32 patients with a mean age of 69+/-11 yrs. An MP3 recorder was used to digitally record Doppler audio signals three times at three sites: the common carotid artery, peak stenosis and region of maximum turbulence. A Fourier-based technique was used to calculate TI, facilitating clinical application without additional ECGgating data. TI was calculated as the standard deviation of Fourier-filtered mean velocity data. We found that TI and clinical PSV were linearly dependent (P<0.001) within the region of maximum turbulence and the precision of all TI measurements was found to be 14%. We have demonstrated the ability to record Doppler waveform data during a conventional carotid exam, and apply off-line custom analysis to Doppler velocity data to produce measurements of TI.

    Mild Crohn's disease (CD) is classified as those patients who are ambulatory, with <10 % weight loss, are eating and drinking without abdominal mass, tenderness, obstructive symptoms, or fever, and endoscopically they have non-progressive mild findings. Initial evaluation of mild CD should focus on assessment for high-risk features requiring more aggressive therapy. In contrast to moderate-to-severe disease, where therapy is focused on mucosal healing, the management of mild CD is focused on symptom management, while exposing the individual to minimal therapeutic risks. Budesonide is the most commonly used medication for mild CD given its safety profile. Assessment of inflammatory markers, in concert with computed-tomography (CT) or magnetic resonance (MR) enterographies and endoscopic studies, should be considered in clinical remission to ensure that mucosal inflammation is not present. Endoscopic inflammation can precede clinical recurrence. Individuals with mild CD require routine vaccination, monitoring for iron-deficiency anemia and vitamin D deficiency, and colorectal cancer screening when appropriate. PMID:27448619

    Purpose Symptomatic radiation pneumonitis (SRP), which decreases quality of life (QoL), is the most common pulmonary complication in patients receiving breast irradiation. If it occurs, acute SRP usually develops 4–12 weeks after completion of radiotherapy and presents as a dry cough, dyspnea and low-grade fever. If the incidence of SRP is reduced, not only the QoL but also the compliance of breast cancer patients may be improved. Therefore, we investigated the incidence SRP in breast cancer patients after hybrid intensity modulated radiotherapy (IMRT) to find the risk factors, which may have important effects on the risk of radiation-induced complications. Methods In total, 93 patients with breast cancer were evaluated. The final endpoint for acute SRP was defined as those who had density changes together with symptoms, as measured using computed tomography. The risk factors for a multivariate normal tissue complication probability model of SRP were determined using the least absolute shrinkage and selection operator (LASSO) technique. Results Five risk factors were selected using LASSO: the percentage of the ipsilateral lung volume that received more than 20-Gy (IV20), energy, age, body mass index (BMI) and T stage. Positive associations were demonstrated among the incidence of SRP, IV20, and patient age. Energy, BMI and T stage showed a negative association with the incidence of SRP. Our analyses indicate that the risk of SPR following hybrid IMRT in elderly or low-BMI breast cancer patients is increased once the percentage of the ipsilateral lung volume receiving more than 20-Gy is controlled below a limitation. Conclusions We suggest to define a dose-volume percentage constraint of IV20< 37% (or AIV20< 310cc) for the irradiated ipsilateral lung in radiation therapy treatment planning to maintain the incidence of SPR below 20%, and pay attention to the sequelae especially in elderly or low-BMI breast cancer patients.

    Patients with obsessive-compulsive disorder (OCD) not only respond to obsessions with perseverative checking, but also engage in more general checking, irrespective of their obsessive concerns. This study investigated whether general checking is specific to OCD and exacerbated when only mild uncertainty is induced. Thirty-one patients with OCD, 26 anxiety- and 31 healthy controls performed a visual search task with eye-tracking and indicated in 50 search displays whether a target was "present" or "absent". Target-present trials were unambiguous, whereas target-absent trials induced mild uncertainty, because participants had to rely on not overlooking the target. Checking behavior was measured by assessing search time and the number of fixations, measured with an eye-tracker. Results showed that in both target-present and target-absent trials patients with OCD searched longer and made more fixations than healthy and anxiety controls. However, the difference in checking behavior between patients with OCD and the control groups was larger in target-absent trials (where mild uncertainty was induced). Anxiety and healthy controls did not differ in checking behavior. Thus, mild uncertainty appears to specifically promote checking in patients with OCD, which has implications for treatment.

    Background Obstructive sleep apnea (OSA) is a chronic and progressive disease. OSA is associated with increased cardiovascular morbidity and mortality, the risk being more frequently encountered with severe degrees of OSA. Increased sympathetic activation and impaired cardiac autonomic control as reflected by depressed baroreceptor reflex sensitivity (BRS) are possible mechanisms involved in the cardiovascular complications of OSA. However, it is not known at what stage of OSA that changes in BRS appear. The aim of this study was to evaluate BRS in patients with mild OSA. Methods The study population consisted of 81 overweight patients with mild OSA and 46 body weight-matched non-OSA subjects. BRS, apnea-hypopnea index, body mass index, and metabolic parameters were assessed. The phenylephrine test was used to measure BRS. Results Patients in the OSA group were slightly but significantly older than the non-OSA population (50.3±9.3 years vs 45.7±11.1 years, P=0.02). Body mass index, percentage body fat, blood pressure, fasting glucose, insulin, and lipid levels did not differ between the OSA patients and non-OSA subjects. Absolute BRS values in patients with mild OSA and non-OSA subjects (9.97±6.70 ms/mmHg vs 10.51±7.16 ms/mmHg, P=0.67) and BRS values proportional to age-related and sex-related reference values (91.4%±22.7% vs 92.2%±21.8%, P=0.84) did not differ from each other. BRS <50% of the sex-specific reference value was found in 6% of patients with mild OSA and in 2% of non-OSA subjects (P=0.29). Conclusion Patients with mild OSA did not show evidence of disturbed BRS in comparison with weight-matched non-OSA controls. PMID:26203292

    Osteonecrosis (ON) is a potentially disabling complication encountered in children who receive chemotherapy for acute lymphoblastic leukemia (ALL). Considering the possible effect of ethnic difference on the clinical features of symptomatic ON in pediatric ALL, we retrospectively evaluated 245 children with ALL who were treated at Chang Gung Memorial Hospital, Linkou, between 2002 and 2011. Six (2.4 %) patients developed symptomatic ON in a total of 17 sites during the follow-up period. Diagnosis of ON was confirmed by X-ray in seven, magnetic resonance imaging in two, and bone scan in three patients. The estimated cumulative incidence of symptomatic ON in newly diagnosed ALL was 3.4 % at 8 years. Four patients received ON-directed surgical interventions, including total hip replacement in three and arthroplasty in one. The incidence of ON was significantly higher among girls (P = 0.03), patients >10 years old (P = 2.2 × 10(-4)), and patients who had received more intensive chemotherapy regimen (P = 0.02). These results indicate that the incidence and risk factors in our institute were similar to those observed in Western countries. Future studies surveying the impact on the quality of life of childhood ALL survivors in Taiwan are warranted.

    Objective The imagination inflation effect is a type of memory distortion defined as an increased tendency to falsely remember that an item has been seen, or an action has been performed, when it has only been imagined. For patients with very mild Alzheimer’s disease (AD), susceptibility to the imagination inflation effect could have significant functional consequences in daily life. Method We assessed whether patients with very mild AD were more or less susceptible to the imagination inflation effect when compared to healthy older adults. In the first session, participants were read an action statement such as “fill the pillbox” and engaged in one of three activities: listened to the statement being read, performed the action, or imagined performing the action. During the second session, participants imagined action statements from the first session as well as new action statements. During the recognition test, participants were asked to determine whether action statements were or were not performed during the first session. Results We found that imagining performing actions increased the tendency of patients with very mild AD to falsely recall the action as having been performed to an extent similar to that of healthy older adults. Conclusion We concluded that, similar to healthy older adults, patients with very mild AD were susceptible to the imagination inflation effect, which we attributed to difficulties with source monitoring and reliance on familiarity.

    Purpose To compare sleep quality and sustained attention of patients with Upper Airway Resistance Syndrome (UARS), mild Obstructive Sleep Apnea (OSA) and normal individuals. Methods UARS criteria were presence of excessive daytime sleepiness (Epworth Sleepiness Scale—ESS—≥ 10) and/or fatigue (Modified Fatigue Impact Scale—MFIS—≥ 38) associated to Apnea/hypopnea index (AHI) ≤ 5 and Respiratory Disturbance Index (RDI) > 5 events/hour of sleep or more than 30% of total sleep time with flow limitation. Mild OSA was considered if the presence of excessive daytime sleepiness (ESS ≥ 10) and/or fatigue (MFIS ≥ 38) associated to AHI ≥ 5 and ≤ 15 events/hour. “Control group” criteria were AHI < 5 events/hour and RDI ≤ 5 events/hour and ESS ≤ 9, without any sleep, clinical, neurological or psychiatric disorder. 115 individuals (34 UARS and 47 mild OSA patients and 34 individuals in “control group”), adjusted for age, gender, body mass index (BMI) and schooling years, performed sleep questionnaires and sustained attention evaluation. Psychomotor Vigilance Task (PVT) was performed five times (each two hours) from 8 a.m. to 4 p.m. Results UARS patients had worse sleep quality (Functional Outcomes of Sleep Questionnaire—FOSQ—and Pittsburgh Sleep Quality Index—PSQI: p < 0.05) and more fatigue than mild OSA patients (p = 0.003) and scored significantly higher in both Beck inventories than “control group” (p < 0.02). UARS patients had more lapses early in the morning (in time 1) compared to the results in the afternoon (time 5) than mild OSA (p = 0.02). Mild OSA patients had more lapses in times 2 than in time 5 compared to “control group” (p = 0.04). Conclusions UARS patients have a worse sleep quality, more fatigue and a worse early morning sustained attention compared to mild OSA. These last had a worse sustained attention than controls.

    We report on a sclerosing bone dysplasia, associated with cutis laxa, enamel dysplasia, and mental retardation. The patient was a 17-year-old Japanese boy of normal height and muscular build. Cutis laxa with prominent veins in the scalp and abdominal wall and delayed eruption of permanent teeth attracted the attention of clinicians in infancy and adolescence, respectively. The clinical manifestations included a progeroid facial appearance with prognathism, wrinkled skin, and interdigital webbing. The intelligence quotient was estimated at 60. Enamel dysplasia was histologically confirmed. Skeletal changes included calvarial hyperostosis, sclerosis of the skull base, an enlarged, sclerotic mandible, broad clavicles and ribs, and diaphyseal undermodeling of the tubular bones. Metaepiphyseal sclerosis or longitudinal striation was found in the long bones. Metaphyseal equivalents of the axial skeleton showed dense osteosclerosis. These clinical and radiological manifestations overlapped with those of Lenz-Majewski syndrome. Unlike the classical phenotype of the disorder, however, he did not show brachymesophalangy with proximal symphalangism or growth failure. The present case may be considered to fall in the mildest end in the phenotypic continuum of Lenz-Majewski syndrome, suggesting that the clinical spectrum of the disorder may be broader than currently thought.

    Background Chronic pain conditions are highly prevalent in patients with mild traumatic brain injury. Supraspinal diffuse axonal injury is known to dissociate brain functional connectivity in these patients. The effect of this dissociated state on supraspinal pain network is largely unknown. A functional magnetic resonance imaging study was conducted to compare the supraspinal pain network in patients with mild traumatic brain injury to the gender and age-matched healthy controls with the hypothesis that the functional connectivities of the medial prefrontal cortices, a supraspinal pain modulatory region to other pain-related sensory discriminatory and affective regions in the mild traumatic brain injury subjects are significantly reduced in comparison to healthy controls. Results The mild traumatic brain injury group (N = 15) demonstrated significantly (P < 0.01, cluster threshold > 150 voxels) less activities in the thalamus, pons, anterior cingulate cortex, insula, dorsolateral prefrontal cortex, and medial prefrontal cortices than the healthy control group (N = 15). Granger Causality Analyses (GCA) indicated while the left medial prefrontal cortices of the healthy control group cast a noticeable degree of outward (to affect) causality inference to multiple pain processing related regions, this outward inference pattern was not observed in the mild traumatic brain injury group. On the other hand, only patients’ bilateral anterior cingulate cortex received multiple inward (to be affected) causality inferences from regions including the primary and secondary somatosensory cortices and the inferior parietal lobe. Resting state functional connectivity analyses indicated that the medial prefrontal cortices of the mild traumatic brain injury group demonstrated a significantly (P < 0.01, F = 3.6, cluster size > 150 voxels) higher degree of functional connectivity to the inferior parietal lobe, premotor and secondary somatosensory cortex

    Noopept is a neuroprotector and nootropics. Literature data revealed the treatment effect of noopept on mild cognitive impairment in patients with discirculatory encephalopathy. The present open prospective study included 60 patients with stroke treated with noopept during 12 months. Cognitive functions were assessed before and after treatment using neuropsychological tests. An analysis of MMSE scores and lateral and categorical associations revealed the significant improvement of cognitive functions after 2 months in patients of the main group compared to the controls. The global assessment of efficacy revealed the mild improvement in the main group while no changes were found in the control group. The results have demonstrated that noopept, used in dose 20 mg daily during 2 months, improves cognitive functions in stroke patients and has a high level of safety. PMID:22500312

    Background: Tremor affects 25% to 58% of patients with multiple sclerosis (MS) and is associated with poor prognosis and increased disability. MS-related tremor is difficult to treat, and data regarding patient-reported characterization and response to treatment are limited. We describe the symptomatic treatment of tremor in 508 enrollees in the North American Research Committee on Multiple Sclerosis (NARCOMS) Registry who self-reported tremor. Methods: From 777 surveys sent to NARCOMS participants who indicated mild or greater tremor using the Tremor and Coordination Scale, we compiled data regarding disability, tremor severity, symptomatic medication use, and reported response to medications. Results: Symptomatic medications reported to reduce tremor were used by 238 respondents (46.9%). Symptomatic medication use was associated with increased rates of unemployment and disability, and many other characteristics were similar between groups. Symptomatic drug use was more likely in participants reporting moderate (53.9%) or severe (51.3%) tremor than in those with mild (36.6%) or totally disabling (35.0%) tremor. This disparity held true across multiple tremor severity scores. The most commonly used drug classes were anticonvulsants (50.8%) and benzodiazepines (46.2%), with gabapentin and clonazepam used most often in their respective classes. Conclusions: Tremor in MS remains poorly treated; less than half of the participants reported benefit from symptomatic medications. Patients with moderate-to-severe tremor are more likely to report tremor benefit than are those with mild or disabling tremor. γ-Aminobutyric acid–active medications were most commonly reported as beneficial.

    Coarctation of the aorta (COA) is an aortic obstruction. A peak-to-peak trans-coarctation pressure gradient (PKdP) of greater than 20 mmHg warns severe COA and the need for interventional/surgical repair. The optimal method and timing of intervention remain uncertain especially for mild COA (PKdP <20 mmHg); even it is unclear if mild COA should be treated at all. Although it was recently suggested that treatment strategies for mild COA may need to be redefined as transcatheter interventions emerge, benefits of such interventions are unclear. We investigated the effects of transcatheter interventions on the aorta and left ventricle (LV) hemodynamics in 11 patients with mild COA using a developed computational fluid dynamics and lumped parameter modeling framework along with particle image velocimetry and clinical measurements. Such interventions can improve aortic hemodynamics to some extent (e.g., time-averaged wall shear stress and kinetic energy were reduced by about 20%). However there is no concomitant effect on the LV hemodynamics (e.g., stroke work and LV pressure were reduced by only less than 4%). Our computational approach can effectively predict clinical conditions. Herein one must question intervention for mild COA, as it has limited utility in reducing myocardial strain.

    Background The worldwide EINSTEIN DVT and EINSTEIN PE studies randomized 8282 patients with acute symptomatic deep-vein thrombosis (DVT) and/or pulmonary embolism (PE) and, for the first time in trials in this setting, included patients in China. This analysis evaluates the results of these studies in this subgroup of patients. Methods A total of 439 Chinese patients who had acute symptomatic DVT (n=211), or PE with or without DVT (n=228), were randomized to receive rivaroxaban (15 mg twice daily for 21 days, followed by 20 mg once daily) or standard therapy of enoxaparin overlapping with and followed by an adjusted-dose vitamin K antagonist, for 3, 6, or 12 months. The primary efficacy outcome was symptomatic recurrent venous thromboembolism. The principal safety outcome was major or non-major clinically relevant bleeding. Results The primary efficacy outcome occurred in seven (3.2%) of the 220 patients in the rivaroxaban group and in seven (3.2%) of the 219 patients in the standard-therapy group (hazard ratio, 1.04; 95% confidence interval 0.36–3.0; p=0.94). The principal safety outcome occurred in 13 (5.9%) patients in the rivaroxaban group and in 20 (9.2%) patients in the standard-therapy group (hazard ratio, 0.63; 95% confidence interval 0.31–1.26; p=0.19). Major bleeding was observed in no patients in the rivaroxaban group and in five (2.3%) patients in the standard-therapy group. In fragile patients (defined as age >75 years, creatinine clearance <50 mL/min, and/or body weight ≤50 kg), the principal safety outcome occurred in four (8.9%) of the 45 patients who received rivaroxaban compared with seven (15.2%) of the 46 patients who received standard therapy. Conclusions In Chinese patients with acute symptomatic DVT and/or PE, rivaroxaban was as efficacious as enoxaparin followed by vitamin K antagonist therapy, with a similar safety profile. The relative efficacy and safety of rivaroxaban compared with enoxaparin/vitamin K antagonist were

    Objective The first purpose of this study was to determine time-to-attainment of symptomatic remissions and recoveries of 2, 4, 6, and 8 years duration for those with borderline personality disorder and comparison subjects with other personality disorders; the second was to determine the stability of these outcomes. Method 290 inpatients meeting both Revised Diagnostic Interview for Borderlines and DSM-III-R criteria for borderline personality disorder and 72 axis II comparison subjects were assessed during their index admission using a series of semistructured interviews. The same instruments were readministered at eight contiguous two-year time periods. Results Borderline patients were significantly slower to achieve remission or recovery (which involved good social and vocational functioning as well as symptomatic remission) than axis II comparison subjects. However, those in both study groups ultimately achieved about the same high rates of remission (borderline patients: 78–99%; axis II comparison subjects: 97–99%) but not recovery (40–60% vs. 75–85%) by the time of the 16-year follow-up. In contrast, symptomatic recurrence (10–36% vs. 4–7%) and loss of recovery (20–44% vs. 9–28%) occurred more rapidly and at substantially higher rates among borderline patients than axis II comparison subjects. Conclusions Taken together, the results of this study suggest that sustained symptomatic remission is substantially more common than sustained recovery from borderline personality disorder. They also suggest that sustained remissions and recoveries are substantially more difficult for borderline patients to attain and maintain than those with other forms of personality disorder.

    Objective The present study was aimed at evaluating the effective radiation dose in patients submitted to PET/CT for the diagnosis of mild cognitive impairment. Materials and Methods TLD-100 detectors inserted into an Alderson Rando® anthropomorphic phantom were utilized to measure the absorbed dose coming from the CT imaging modality. The anthropomorphic phantoms (male and female adult versions) were submitted to the same technical protocols for patients’ images acquisition. The absorbed dose resulting from the radiopharmaceutical injection was estimated by means of the model proposed by the ICRP publication 106. Results The effective dose in patients submitted to this diagnostic technique was approximately (5.34 ± 1.99) mSv. Conclusion Optimized protocols for calculation of radioactive activity injected into patients submitted to this diagnostic technique might contribute to reduce the effective radiation dose resulting from PET/CT in the diagnosis of mild cognitive impairment.

    To evaluate the efficiency menantine (antagonist of NMDA-type glutamate receptor) for treatment of the mild stage of Alzheimer and vascular dementia, we conducted a comprehensive neurological, experimental psychological, neurophysiological examination of 33 patients. It was found that the treatment course with memantine, 5-10 mg daily during 3 months resulted in reducing the severity of cognitive impairment, improved bioelectric activity of the brain in patients with dementia, and also helped to improve the patients' behavior, which resulted in stress loads on the surrounding people. It is shown that the treatment was well tolerated, and memantine may be recommended as one of the drugs for treatment of cognitive impairment accompanying aging in the mild stage of dementia of different genesis.

Previous studies focused mainly on patients with severe psoriasis who were found to have increased markers of early atherosclerosis, higher intima-media thickness (IMT) values. Aim To evaluate the association between the severity or duration of psoriasis and carotid IMT in patients with mild and moderate psoriasis. Material and methods We studied seventy four patients with mild and moderate psoriasis. Clinical assessment and common carotid artery (CCA) IMT measurements were performed in all patients. Results The mean CCA IMT value was 1.03 ±0.37 mm, mean PASI score (psoriasis area severity index) was 18.6 ±10.5. There was a significant association between PASI score and IMT values (r = 0.33; p = 0.007) adjusted for age, psoriasis duration, blood pressure and smoking. However, we found no correlations between carotid IMT and disease duration or other clinical variables. Conclusions The severity of psoriasis is associated with carotid IMT even in patients with mild and moderate psoriasis.

    Acute pancreatitis and acalculous cholecystitis have been occasionally reported in primary acute symptomatic Epstein-Barr virus infection. We completed a review of the literature and retained 48 scientific reports published between 1966 and 2016 for the final analysis. Acute pancreatitis was recognized in 14 and acalculous cholecystitis in 37 patients with primary acute symptomatic Epstein-Barr virus infection. In all patients, the features of acute pancreatitis or acalculous cholecystitis concurrently developed with those of primary acute symptomatic Epstein-Barr virus infection. Acute pancreatitis and acalculous cholecystitis resolved following a hospital stay of 25days or less. Acalculous cholecystitis was associated with Gilbert-Meulengracht syndrome in two cases. In conclusion, this thorough analysis indicates that acute pancreatitis and acalculous cholecystitis are unusual but plausible complications of primary acute symptomatic Epstein-Barr virus infection. Pancreatitis and cholecystitis deserve consideration in cases with severe abdominal pain. These complications are usually rather mild and resolve spontaneously without sequelae. PMID:27434148

    Background Symptomatic thoracic herniated discs have historically been treated using open exposures (i.e., thoracotomy), posing a clinical challenge given the approach related morbidity. Lateral interbody fusion (LIF) is one modern minimally disruptive alternative to thoracotomy. The direct lateral technique for lumbar pathologies has seen a sharp increase in procedural numbers; however application of this technique in thoracic pathologies has not been widely reported. Methods This study presents the results of three cases where LIF was used to treat symptomatic thoracic disc herniations. Indications for surgery included thoracic myelopathy, radiculopathy and discogenic pain. Patients were treated with LIF, without supplemental internal fixation, and followed for 24 months postoperatively. Results: Average length of hospital stay was 5 days. One patient experienced mild persistent neuropathic thoracic pain, which was managed medically. At 3 months postoperative all patients had returned to work and by 12 months all patients were fused. From preoperative to 24-month follow-up there were mean improvements of 83.3% in visual analogue scale (VAS), 75.3% in Oswestry Disability Index (ODI), and 79.2% and 17.4% in SF-36 physical (PCS) and mental component scores (MCS), respectively. Conclusions LIF is a viable minimally invasive alternative to conventional approaches in treating symptomatic thoracic pathology without an access surgeon, rib resection, or lung deflation.

    OBJECT Symptomatic intracranial atherosclerotic disease (ICAD) has a high risk of recurrent stroke. Genetic polymorphisms in CYP2C19 and CES1 are associated with adverse outcomes in cardiovascular patients, but have not been studied in ICAD. The authors studied CYP2C19 and CES1 single-nucleotide polymorphisms (SNPs) in symptomatic ICAD patients. METHODS Genotype testing for CYP2C19*2, (*)3, (*)8, (*)17 and CES1 G143E was performed on 188 adult symptomatic ICAD patients from 3 medical centers who were medically managed with clopidogrel and aspirin. Testing was performed prospectively at 1 center, and retrospectively from a DNA sample biorepository at 2 centers. Multiple logistic regression and Cox regression analysis were performed to assess the association of these SNPs with the primary endpoint, which was a composite of transient ischemic attack (TIA), stroke, myocardial infarction, or death within 12 months. RESULTS The primary endpoint occurred in 14.9% of the 188 cases. In multiple logistic regression analysis, the presence of the CYP2C19 loss of function (LOF) alleles *2, *3, and *8 in the medically managed patients was associated with lower odds of primary endpoint compared with wild-type homozygotes (odds ratio [OR] 0.13, 95% CI 0.03-0.62, p = 0.0101). Cox regression analysis demonstrated the CYP2C19 LOF carriers had a lower risk for the primary endpoint, with hazard ratio (HR) of 0.27 (95% CI 0.08-0.95), p = 0.041. A sensitivity analysis of a secondary composite endpoint of TIA, stroke, or death demonstrated a significant trend in multiple logistic regression analysis of CYP2C19 variants, with lower odds of secondary endpoint in patients carrying at least 1 LOF allele (*2, *3, *8) than in wild-type homozygotes (OR 0.27, 95% CI 0.06-1.16, p = 0.078). Cox regression analysis demonstrated that the carriers of CYP2C19 LOF alleles had a lower risk forthe secondary composite endpoint (HR 0.22, 95% CI 0.05-1.04, p = 0.056). CONCLUSIONS This is the first study

    This study evaluated the working memory performance of 18 patients experiencing their first onset of mild depression without treatment and 18 healthy matched controls. The results demonstrated that working memory impairment in patients with mild depression occurred when memorizing the position of a picture but not when memorizing the pictures themselves. There was no significant difference between the two groups in the emotional impact on the working memory, indicating that the attenuation of spatial working memory was not affected by negative emotion; however, cognitive control selectively affected spatial working memory. In addition, the accuracy of spatial working memory in the depressed patients was not significantly reduced, but the reaction time was significantly extended compared with the healthy controls. This finding indicated that there was no damage to memory encoding and function maintenance in the patients but rather only impaired memory retrieval, suggesting that the extent of damage to the working memory system and cognitive control abilities was associated with the corresponding depressive symptoms. The development of mild to severe depressive symptoms may be accompanied by spatial working memory damage from the impaired memory retrieval function extending to memory encoding and memory retention impairments. In addition, the impaired cognitive control began with an inadequate capacity to automatically process internal negative emotions and further extended to impairment of the ability to regulate and suppress external emotions. The results of the mood-congruent study showed that the memory of patients with mild symptoms of depression was associated with a mood-congruent memory effect, demonstrating that mood-congruent memory was a typical feature of depression, regardless of the severity of depression. This study provided important information for understanding the development of cognitive dysfunction.

    Osteoarthritis (OA) of the hip is a common cause of hip pain. The arthroscopic management of patients with femoro-acetabular impingement (FAI) has been reported to yield good outcomes. The purpose of this study was to report on outcome following the arthroscopic treatment of patients with FAI in the presence of mild to moderate OA. Seventy-five patients undergoing arthroscopic surgery for FAI, all with preoperative radiological signs of mild to moderate OA were prospectively included in this study. A 2-year follow-up, using web-based patient-reported outcome measures, including the International Hip Outcome Tool (iHOT-12), Copenhagen Hip and Groin Outcome (HAGOS), EQ-5D, Hip Sports Activity Scale (HSAS) for physical activity level and a visual analogue scale (VAS) for overall hip function, was performed, complemented by a radiographic evaluation. At follow-up (mean 26 months, SD 5), five patients (7%) had undergone total hip arthroplasty, leaving 70 patients for the analysis. Preoperative scores compared with those obtained at the 2-year follow-up revealed significant improvements (P < 0.0001) for all measured outcomes; the iHOT-12 (42 versus 65), VAS for global hip function (48 versus 68), HSAS (2.5 versus 3), EQ5D index (0.62 versus 0.76), EQ VAS (69 versus 75) and different HAGOS subscales (54 versus 72, 47 versus 67, 56 versus 75, 40 versus 61, 33 versus 56, 31 versus 55). At follow-up, 56 (82%) patients reported that they was satisfied with the outcome of surgery. Arthroscopic treatment for patients with FAI in the presence of mild to moderate OA resulted in statistically significant and clinically relevant improvements in outcome measures related to pain, symptoms, function, physical activity level and quality of life in the majority of patients.

  6. Arginine improves peroxisome functioning in cells from patients with a mild peroxisome biogenesis disorder

    PubMed Central

    2013-01-01

    Background Zellweger spectrum disorders (ZSDs) are multisystem genetic disorders caused by a lack of functional peroxisomes, due to mutations in one of the PEX genes, encoding proteins involved in peroxisome biogenesis. The phenotypic spectrum of ZSDs ranges from an early lethal form to much milder presentations. In cultured skin fibroblasts from mildly affected patients, peroxisome biogenesis can be partially impaired which results in a mosaic catalase immunofluorescence pattern. This peroxisomal mosaicism has been described for specific missense mutations in various PEX genes. In cell lines displaying peroxisomal mosaicism, peroxisome biogenesis can be improved when these are cultured at 30°C. This suggests that these missense mutations affect the folding and/or stability of the encoded protein. We have studied if the function of mutant PEX1, PEX6 and PEX12 can be improved by promoting protein folding using the chemical chaperone arginine. Methods Fibroblasts from three PEX1 patients, one PEX6 and one PEX12 patient were cultured in the presence of different concentrations of arginine. To determine the effect on peroxisome biogenesis we studied the following parameters: number of peroxisome-positive cells, levels of PEX1 protein and processed thiolase, and the capacity to β-oxidize very long chain fatty acids and pristanic acid. Results Peroxisome biogenesis and function in fibroblasts with mild missense mutations in PEX1, 6 and 12 can be improved by arginine. Conclusion Arginine may be an interesting compound to promote peroxisome function in patients with a mild peroxisome biogenesis disorder. PMID:24016303

    Objectives: To compare tooth size between subjects with mild, moderate and severe hypodontia and a control group. Material and Methods: The study comprised 120 patients with hypodontia divided into three groups of 40 mild (≤2 teeth congenitally missing), 40 moderate (3-5 teeth congenitally missing) and 40 severe (≥6 teeth congenitally missing) hypodontia; and 40 age and sex matched controls. Tooth size was recorded by measuring the mesiodistal and buccolingual dimensions of all fully erupted teeth on study models using digital callipers and compared between all hypodontia and control groups using Two-way ANOVA and Post Hoc Tests of subgroup comparison. Results: Two-way ANOVA revealed patients with hypodontia had significantly smaller mesiodistal and buccolingual tooth dimensions compared with controls (p<0.05). Furthermore patients with more severe hypodontia demonstrated significantly smaller tooth dimensions than those in the mild and moderate hypodontia subgroups (p<0.05). The most affected tooth in terms of tooth size reduction was the maxillary lateral incisor and the least affected tooth was the mandibular first molar. Conclusion: Patients with hypodontia have smaller tooth dimensions than control. Tooth size appears to be affected by the degree of hypodontia, with severe hypodontia having a greater effect on tooth size reduction. The findings of this study may contribute to understanding the aetiology of hypodontia and aid the multidisciplinary management of this complex condition. PMID:27583048

    Purpose Financial capacity (FC) is an instrumental activity of daily living (IADL) critical to independent functioning and sensitive to cognitive impairment in dementia. Little is known about FC in cognitively impaired patients with Parkinson’s disease (PD). The present study investigated FC in PD patients with prodromal and clinical dementia. Methods Participants were 20 older controls and 35 PD patients who met consensus criteria for either mild cognitive impairment (PD-MCI, n=18) or PD dementia (PDD, n=17). FC was assessed using a standardized performance based measure consisting of 9 domain and two global scores (Financial Capacity Instrument; FCI)(1). FCI domain and global performance scores were compared across groups. Capacity impairment ratings (no impairment, mild/moderate impairment, severe impairment) were calculated for each PD patient’s domain and global scores. Results Relative to controls, PD-MCI patients were impaired on both FCI global scores and domains of basic monetary skills, financial concepts, and investment decision-making. Relative to both controls and PD-MCI patients, PDD patients were impaired on virtually all FCI variables. With respect to impairment ratings, greater than 50% of PD-MCI patients and greater than 90% of PDD patients were classified as either mild/moderate or severely impaired on the two FCI global scores. Conclusions Impairment of financial capacity is already present in PD-MCI and is advanced in PDD. Complex cognitively-mediated IADLs such as financial capacity appear to be impaired early in the course of PD dementia. PMID:23899743

    Background: Many studies showed a better recovery of cognitive function after administration of exogenous lactate during moderate-severe traumatic brain injury. However, the study evaluating lactate effect on mild traumatic brain injury is still limited. Aims: To evaluate the effect of exogenous lactate on cognitive function in mild traumatic brain injury patients. Settings and Design: Prospective, single blind, randomized controlled study on 60 mild traumatic brain injury patients who were undergoing neurosurgery. Materials and Methods: Subjects were randomly assigned into hyperosmolar sodium lactate (HSL) group or hyperosmolar sodium chloride (HSS) group. Patients in each group received either intravenous infusion of HSL or NaCl 3% at 1.5 ml/KgBW within 15 min before neurosurgery. During the surgery, patients in both groups received maintenance infusion of NaCl 0.9% at 1.5 ml/KgBW/hour. Statistical Analysis: Cognitive function, as assessed by Mini-Mental State Examination (MMSE) score at 24 h, 30 and 90 days post-surgery, was analyzed by Anova repeated measures test. Results: The MMSE score improvement was significantly better in HSL group than HSS group (P < 0.001). In HSL group the MMSE score improved from 16.00 (13.75-18.00) at baseline to 21.00 (18.75-22.00); 25.00 (23.75-26.00); 28.00 (27.00-29.00) at 24 h, 30, 90 days post-surgery, respectively. In contrast, in HSS group the MMSE score almost unchanged at 24 h and only slightly increased at 30 and 90 days post-surgery. Conclusions: Hyperosmolar sodium lactate infusion during mild traumatic brain injury improved cognitive function better than sodium chloride 3%. PMID:27057222

    Background Long-term continuous positive airway pressure (CPAP) usage varies between individuals. It would be of value to be able to identify those who are likely to benefit from CPAP (and use it long term), versus those who would not, and might therefore benefit from additional help early on. First, we explored whether baseline characteristics predicted CPAP usage in minimally symptomatic obstructive sleep apnoea (OSA) patients, a group who would be expected to have low usage. Second, we explored if early CPAP usage was predictive of longer-term usage, as has been shown in more symptomatic OSA patients. Methods The MOSAIC trial was a multi-centre randomised controlled trial where minimally symptomatic OSA patients were randomised to CPAP, or standard care, for 6 months. Here we have studied only those patients randomised to CPAP treatment. Baseline characteristics including symptoms, questionnaires [including the Epworth sleepiness score (ESS)] and sleep study parameters were recorded. CPAP usage was recorded at 2–4 weeks after initiation and after 6 months. The correlation and association between baseline characteristics and 6 months CPAP usage was assessed, as was the correlation between 2 and 4 weeks CPAP usage and 6 months CPAP usage. Results One hundred and ninety-five patients randomised to CPAP therapy had median [interquartile range (IQR)] CPAP usage of 2:49 (0:44, 5:13) h:min/night (h/n) at the 2–4 weeks visit, and 2:17 (0:08, 4:54) h/n at the 6 months follow-up visit. Only male gender was associated with increased long-term CPAP use (male usage 2:56 h/n, female 1:57 h/n; P=0.02). There was a moderate correlation between the usage of CPAP at 2–4 weeks and 6 months, with about 50% of the variability in long-term use being predicted by the short-term use. Conclusions In patients with minimally symptomatic OSA, our study has shown that male gender (and not OSA severity or symptom burden) is associated with increased long-term use of CPAP at 6 months

    Evaluated the effectiveness of Pronoran® for treatment of elderly patients with syndrome of mild cognitive impairment (MCI) with underlying dyscirculatory encephalopathy. The study involved 48 people: I (main) group--27 patients who in addition to basic therapy received Pronoran®, II (control) group--21 patients, received only basic therapy. We found that exposure to a 3-month treatment course for patients of the I (main) group showed significant improvement in terms of indicators characterizing orientation in space, short-term memory, counting ability, concentration, psychomotor pace, ability to learn. In addition, the treatment course was accompanied by improved emotional state, positive changes in the coefficients of the spectral power qEEG for patients. At the same time, the patients in the II (control) group didn't show significant changes in the studied parameters. PMID:26118093

    Memory impairment is a typical characteristic of patients with subcortical vascular mild cognitive impairment (svMCI) or with amnestic mild cognitive impairment (aMCI). The hippocampus, which plays an important role in the consolidation of information from short-term memory to long-term memory, is a heterogeneous structure that consists of several anatomically and functionally distinct subfields. However, whether distinct hippocampal subfields are differentially and selectively affected by svMCI pathology and whether these abnormal changes in hippocampal subfields are different between svMCI and aMCI patients are largely unknown. A total of 26 svMCI patients, 26 aMCI patients and 26 healthy controls matched according to age, gender and years of education were enrolled in this study. We utilized an automated hippocampal subfield segmentation method provided by FreeSurfer to estimate the volume of several hippocampal subfields, including the cornu ammonis (CA) areas, the dentate gyrus (DG), the subiculum and the presubiculum. Compared with controls, the left subiculum and presubiculum and the right CA4/DG displayed significant atrophy in patients with svMCI. Interestingly, we also found significant differences in the volume of the right CA1 between the svMCI and aMCI groups. Taken together, our results reveal region-specific vulnerability of hippocampal subfields to svMCI pathology and identify distinct hippocampal subfield atrophy patterns between svMCI and aMCI patients.

    Dried flowers and buds of Sophora japonica (Huaihua) are used in China, Japan and Korea for treating haematemesis and bleeding haemorrhoids. This study compared the clinical safety and efficacy of a Sophora flower formula with a placebo for the conservative treatment of symptomatic haemorrhoids. The study was a prospective, double-blind, randomized placebo-controlled trial. The clinical effective rate, symptom score and the incidence of important clinical events were used as observation indices to evaluate the effect of the Sophora flower formula. The results showed that after 7 days of treatment, improvement was observed in 87.0% of the patients' major symptoms in the Sophora flower formula group compared with 81.8% of those in the placebo group. After 14 days, 78.2% patients in the Sophora flower formula group were asymptomatic, whereas 40.9% of those in the placebo group exhibited residual symptoms. However, the difference between both groups was not statistically significant. As the bowel habits of the patients improved and as the patients took sitz baths, their symptoms improved drastically, regardless of the use of the Sophora flower formula. These findings indicate that the traditional Chinese Sophora flower formula is clinically safe; however, its effects on haemorrhoids need to be studied in a larger sample size and with different dosages. The present study results may be a potential clinical reference for physicians prescribing medications for patients with symptomatic haemorrhoids. PMID:24146460

    In the present experiment, children with mild spastic cerebral palsy and a control group carried out a memory recognition task. The key question was if errors of the patient group are foreshadowed by attention lapses, by weak motor preparation, or by both. Reaction times together with event-related potentials associated with motor preparation (frontal late contingent negative variation), attention (parietal P300), and response evaluation (parietal error-preceding positivity) were investigated in instances where 3 subsequent correct trials preceded an error. The findings indicated that error responses of the patient group are foreshadowed by weak motor preparation in correct trials directly preceding an error.

    Mild traumatic brain injury (TBI) is often an invisible injury that is poorly understood and its sequelae can be difficult to diagnose. Recent neuroimaging studies on patients diagnosed with mild TBI (mTBI) have demonstrated an increase in hyperintense brain lesions on T2-weighted MR images. This paper presents an in-depth analysis of the multi-modal and morphological properties of T2 hyperintensity lesions among service members diagnosed with mTBI. A total of 790 punctuate T2 hyperintensity lesions from 89 mTBI subjects were analyzed and used to characterize the lesions based on different quantitative measurements. Morphological analysis shows that on average, T2 hyperintensity lesions have volumes of 23mm3 (+/-24.75), a roundness measure of 0.83 (+/-0.08) and an elongation of 7.90 (+/-2.49). The frontal lobe lesions demonstrated significantly more elongated lesions when compared to other areas of the brain.

    Congenital mild bleeding disorders (MBDs) are very prevalent and are the source of frequent diagnostic problems. Most MBDs are categorized as disorders of primary hemostasis (ie, type 1 VWD and platelet function disorders), but mild or moderate deficiencies of clotting factors and some rare hyperfibrinolytic disorders are also included. These patients have abnormal bleeding from the skin and mucous membranes, menorrhagia, and disproportionate hemorrhages after trauma, invasive procedures, and surgery. This review addresses the main problems that physicians and hemostasis laboratories confront with the diagnosis of these patients, including: discerning normal/appropriate from pathological bleeding, the role and yield of screening tests, the lack of distinctive bleeding pattern among the different diseases, the inherent difficulties in the diagnosis of type 1 VWD and the most common platelet functional disorders, improvements in assays to measure platelet aggregation and secretion, and the evidence that most of the patients with MBDs end up without a definite diagnosis after exhaustive and repeated laboratory testing. Much research is needed to determine the pathogenesis of bleeding in MBD patients. Better standardization of current laboratory assays, progress in the knowledge of fibrinolytic mechanisms and their laboratory evaluation, and new understanding of the factors contributing to platelet-vessel wall interaction, along with the corresponding development of laboratory tools, should improve our capacity to diagnose a greater proportion of patients with MBDs.

    Little is known regarding plaque distribution, composition, and the association with inflammation in type 2 diabetes mellitus (DM2). This study aimed to assess the relationship between coronary plaque subtypes and high-sensitivity C-reactive protein levels. Coronary CTA were performed in 98 symptomatic DM2 patients and 107 non-DM2 patients using a 256-slice CT. The extent and types of plaque as well as luminal narrowing were evaluated. Patients with DM2 were more likely to have significant stenosis (>50%) with calcified plaques in at least one coronary segment (p < 0.01); the prevalence rates of diffuse calcified plaques in the DM2 and non-DM2 groups were 31.6% and 4.7%, respectively (p < 0.01). Plasma hs-CRP levels in DM2 with calcified plaques were higher compared with values obtained for the non-DM2 group (p < 0.01). In conclusion, combination of coronary CTA and hs-CRP might improve risk stratification in symptomatic DM2 patients. PMID:27579325

    There are various anticholinesterase inhibitors (AChEIs) for the symptomatic treatment of mild to moderate Alzheimer's disease (AD). All AChEIs have shown greater efficacy than placebo in randomized, double-blind, parallel-group clinical trials. No differential studies have yet been made of the efficacy between all AChEIs. The study aims to determine the differential efficacy of the AChEIs with respect to a historical sample of patients with AD that were not treated with AChEIs. An open-label, prospective, observational study with a retrospective control group was undertaken to examine the evolution of the cognitive function over a 6-month period. The patients were assessed with the Mini-Mental State Examination (MMSE) at study entry and at 6 months. A general linear model was applied for repeated measurements with the MMSE score as the dependent variable, treatment type as an independent variable and the severity of the deterioration, age and the MMSE baseline score as covariables. Of the sample of 147 patients, 40 initiated treatment with donepezil, 32 with galantamine, 30 with rivastigmine and 45 were part of a historical sample of the memory clinic patients between 1991 and 1996 that had not been treated with AChEIs. The average age was 73.7 years (SD = 6.9; range = 52-86), 67.3% were women, 78.2% of the cases were mild and the MMSE baseline score was 18.1 points (range = 11-27). No significant intergroup differences were observed in these variables. The average doses of donepezil, galantamine and rivastigmine were 5.87 mg/day (SD = 1.92), 14.81 mg/day (SD = 6.25) and 6.41 mg/day (SD = 1.82), respectively. At 6 months, the difference in the MMSE score with respect to the untreated group was 1.6 points for donepezil (95% CI 0.79-2.37; p < 0.001), 0.99 points for galantamine (95% CI 0.14-1.85; p = 0.01) and 0.90 points for rivastigmine (95% CI 0.05-1.74; p = 0.03). No significant differences were observed in the efficacy among the groups treated with AChEIs (p

    Background: Physical therapy (PT) is often prescribed for patients with rotator cuff tears. The extent to which PT influences strength, range of motion (ROM), and patient-reported outcomes has been studied extensively, but the effect of PT on in vivo joint kinematics is not well understood. Purpose: To assess the influence of symptomatic rotator cuff pathology and the effects of PT on shoulder motion, strength, and patient-reported outcomes. Study Design: Controlled laboratory study. Methods: Twenty-five patients with a symptomatic rotator cuff tear and 25 age-matched asymptomatic control subjects were recruited. Shoulder motion was measured using a biplane radiography imaging system, strength was assessed with a Biodex dynamometer, and patient-reported outcomes were assessed using the Western Ontario Rotator Cuff Index and visual analog scale (VAS) pain scores. Data were acquired from the patients before and after 8 weeks of physical therapy. Data were acquired at 1 time point for the control subjects. Results: Compared with the control subjects, patients with a symptomatic rotator cuff tear had significantly worse pain/function scores (P < .01); less ROM (P < .01); lower abduction (ABD), external rotation (ER), and internal rotation (IR) strength (P < .01); less scapulothoracic posterior tilt (P = .05); and lower glenohumeral joint elevation (P < .01). Physical therapy resulted in improved pain/function scores (P < .01), increased ROM (P < .02), increased scapulothoracic posterior tilt (P = .05), increased glenohumeral joint elevation (P = .01), and decreased acromiohumeral distance (AHD) (P = .02). Conclusion: Compared with age-matched controls, patients had worse pain/function scores, less ROM, and lower ABD, ER, and IR strength. Patients also had less scapulothoracic anteroposterior tilt, less glenohumeral joint elevation, and an altered glenohumeral joint contact path. PT resulted in improved pain/function scores, increased ROM, greater posterior

    Dyspnea, exercise intolerance, and activity restriction are already apparent in mild chronic obstructive pulmonary disease (COPD). However, patients may not seek medical help until their symptoms become troublesome and persistent and significant respiratory impairment is already present; as a consequence, further sustained physical inactivity may contribute to disease progression. Ventilatory and gas exchange impairment, cardiac dysfunction, and skeletal muscle dysfunction are present to a variable degree in patients with mild COPD, and collectively may contribute to exercise intolerance. As such, there is increasing interest in evaluating exercise tolerance and physical activity in symptomatic patients with COPD who have mild airway obstruction, as defined by spirometry. Simple questionnaires, eg, the modified British Medical Research Council dyspnea scale and the COPD Assessment Test, or exercise tests, eg, the 6-minute or incremental and endurance exercise tests can be used to assess exercise performance and functional status. Pedometers and accelerometers are used to evaluate physical activity, and endurance tests (cycle or treadmill) using constant work rate protocols are used to assess the effects of interventions such as pulmonary rehabilitation. In addition, alternative outcome measurements, such as tests of small airway dysfunction and laboratory-based exercise tests, are used to measure the extent of physiological impairment in individuals with persistent dyspnea. This review describes the mechanisms of exercise limitation in patients with mild COPD and the interventions that can potentially improve exercise tolerance. Also discussed are the benefits of pulmonary rehabilitation and the potential role of pharmacologic treatment in symptomatic patients with mild COPD. PMID:24940054

    A 69-year-old man with alcohol dependence and mild cognitive impairment (MCI) suffered from repeated tonic-clonic seizures. The seizures typically occurred several hours after his last alcohol intake at home (early withdrawal seizure) and 22 days after his last intake of alcohol (14 days after the last dose of diazepam substituting for alcohol: late withdrawal seizure) on the ward. Psychiatrists in charge of this patient found it difficult to attribute his seizures to alcohol withdrawal syndrome (AWS) because of the atypical onset. The patient responded to diazepam resumption and valproate combination. This case highlights the need to always consider AWS as a possible cause of seizures and to gradually decrease diazepam as a substitute for alcohol. Moreover, in this patient, MCI may have induced vulnerability in the brain for AWS and the patients' older age might have decreased liver function leading to delayed onset of the seizures after diazepam withdrawal.

    A variety of studies demonstrated that some forms of memory for music are spared in dementia, but only few studies have investigated patients with early stages of dementia. In this pilot-study we tested working memory for music in patients with mild cognitive impairment (MCI) and early stage Alzheimer's disease (AD) with a newly created test. The test probed working memory using 7 gradually elongated tone-lines and 6 chords which were each followed by 3 similar items and 1 identical item. The participants of the study, namely 10 patients with MCI, 10 patients with early stage AD and 23 healthy subjects were instructed to select the identical tone-line or chord. Subjects with MCI and early AD showed significantly reduced performance than controls in most of the presented tasks. In recognizing chords MCI- participants surprisingly showed an unimpaired performance. The gradual increase of the impairment during the preclinical phase of AD seems to spare this special ability in MCI.

    Third-generation EGFR TKI has been approved in the US and EU for the treatment of EGFR mutant T790M+ NSCLC patients that are resistant to first- or second generation EGFR TKIs. Here we report a patient who developed resistance to osimertinib after a confirmed partial response for 9 months. Pre-osimertinib and post-osimertinib tumor biopsy revealed the emergence of high level of MET amplification (30 copies) post osimertinib treatment. Patient was treated with single agent crizotinib, a known MET inhibitor, with transient symptomatic benefit. MET amplification is one potential resistance mechanism to osimertinib and combination of osimertinib and a MET inhibitor should be investigated post-osimertinib progression in EGFR mutant T790M+ NSCLC patients whose harbored acquired MET amplification.

    AIM: To compare the clinical efficacy of the second-generation H2RA lafutidine with that of lansoprazole in Japanese patients with mild gastroesophageal reflux disease (GERD). METHODS: Patients with symptoms of GERD and a diagnosis of grade A reflux esophagitis (according to the Los Angeles classification) were randomized to receive lafutidine (10 mg, twice daily) or lansoprazole (30 mg, once daily) for an initial 8 wk, followed by maintenance treatment comprising half-doses of the assigned drug for 24 wk. The primary endpoint was the frequency and severity of heartburn during initial and maintenance treatment. The secondary endpoints were the sum score of questions 2 and 3 in the Gastrointestinal Symptom Rating Scale (GSRS), and the satisfaction score. RESULTS: Between April 2012 and March 2013, a total of 53 patients were enrolled, of whom 24 and 29 received lafutidine and lansoprazole, respectively. After 8 wk, the frequency and severity of heartburn was significantly reduced in both groups. However, lafutidine was significantly inferior to lansoprazole with regard to the severity of heartburn during initial and maintenance treatment (P = 0.016). The sum score of questions 2 and 3 in the GSRS, and satisfaction scores were also significantly worse in the lafutidine group than the lansoprazole group (P = 0.0068 and P = 0.0048, respectively). CONCLUSION: The clinical efficacy of lafutidine was inferior to that of lansoprazole, even in Japanese patients with mild GERD. PMID:27340360

    In this study, we focused on acceptance of memory impairment and satisfaction with life in patients with mild to moderate Alzheimer's disease (AD). We interviewed 71 consecutive patients with AD and asked (1) whether they had memory loss, (2) whether they found trouble in life, and (3) how their daily life was. We categorized the patients into three groups based on awareness of memory loss and reference to the cause of memory loss. Cognitive functions were lower in patients who were not aware of memory loss. The rate of satisfaction with life was the highest in patients who were not aware of memory loss, and was the lowest in patients who complained of memory loss with reference to the cause of memory loss, indicating that patients could hardly accept their lives when memory impairment was a serious issue. However, in these patients, depression scores were not high, suggesting that they may somehow adapt themselves to their current status by defining the reason for memory loss. In patients who complained of memory impairment but did not refer to the cause of memory loss, there was a variation in awareness of memory loss and satisfaction with life. The present study indicated that we have to provide individual care and support for AD patients considering their level of acceptance of memory impairment.

    Purpose The purpose of this study was to compare the diagnostic performance of SPECT/CT and MRI in patients with ankle and foot pain, with regard to the lesion types. Materials and Methods Fifty consecutive patients with ankle and foot pain, who underwent 99mTc-MDP SPECT/CT and MRI, were retrospectively enrolled in this study. Symptomatic lesions were determined based on clinical examination and response to treatment. On MRI and SPECT/CT, detected lesions were classified as bone, ligament/tendon, and joint lesions. Uptake on SPECT/CT was assessed using a 4-grade system. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of SPECT/CT and MRI were evaluated in all detected lesions and each lesion type. Diagnostic value of uptake grade was analyzed using receiver-operating characteristics (ROC) curve analysis, and diagnostic performance was compared using Chi-square or McNemar tests. Results In overall lesions, the sensitivity, PPV and NPV of SPECT/CT for symptomatic lesions were 93%, 56%, 91%, and they were 98%, 48%, 95% for MRI. There was no significant difference between SPECT/CT and MRI. However, the specificity of SPECT/CT was significantly higher than that of MRI (48% versus 24%, P = 0.016). Uptake grade on SPECT/CT was significantly higher in symptomatic lesions (P < 0.001), and its area under curve on ROC analysis was 0.787. In the analysis of each lesion type, the specificity of SPECT/CT was poor in joint lesions compared with other lesion types and MRI (P < 0.001, respectively). MRI exhibited lower specificity than SPECT/CT in bone lesions (P = 0.004) and ligament/tendon lesions (P < 0.001). Conclusions SPECT/CT has MRI-comparable diagnostic performance for symptomatic lesions in ankle and foot pain patients. SPECT/CT and MRI exhibit different diagnostic specificity in different lesion types. SPECT/CT may be used as a complementary imaging method to MRI for enhancing diagnostic specificity. PMID:25668182

    Fatal pulmonary embolism is the third most common cause of death after major trauma. We hypothesised that the Trauma Embolic Scoring System (TESS) would have adequate calibration and discrimination in a group of severely injured trauma patients in predicting venous thromboembolism (VTE), and could be used to predict fatal and non-fatal symptomatic pulmonary embolism. Calibration and discrimination of the TESS were assessed by the slope and intercept of the calibration curve and the area under the receiver operating characteristic curve, respectively. Of the 357 patients included in the study, 74 patients (21%) developed symptomatic VTE after a median period of 14 days following injury. The TESS predicted risks of VTE were higher among patients who developed VTE than those who did not (14 versus 9%, P=0.001) and had a moderate ability to discriminate between patients who developed VTE and those who did not (area under the receiver operating characteristic curve 0.71, 95% confidence interval 0.65 to 0.77). The slope and intercept of the calibration curve were 2.76 and 0.34, respectively, suggesting that the predicted risks of VTE were not sufficiently extreme and overall, underestimated the observed risks of VTE. Using 5% predicted risk of VTE as an arbitrary cut-point, TESS had a high sensitivity and negative predictive value (both ≥0.97) in excluding fatal and non-fatal pulmonary embolism. The TESS had a reasonable ability to discriminate between patients who developed VTE and those who did not and may be useful to select different strategies to prevent VTE in severely injured patients.

    This paper describes the design of a prototype telecare system, which allows to provide home care to patients with mild cognitive impairment and thus ensures their permanence in their usual environment. Telecare is oriented towards people who require constant attention due to conditions of advanced age, illness, physical risk or limited capabilities. Telecare offers these people a greater degree of independence. QFD methodology is used to develop electronic devices intended to monitor the environment and physiological state of the user continuously, providing communication between the telecare system and a monitoring center in order to take the most appropriate actions in any abnormal event.

    Traumatic brain injury (TBI) remains a major public health and socio-economic problem, and 70-90% of all TBIs are classified as mild. Mild TBIs and concussions are mostly considered to be non-serious conditions with symptoms subsiding within a few days or weeks. However in 10-15% of patients, the symptoms persist one year after concussion and mostly include headache, fatigue, irritability, and cognitive problems (e.g. memory, concentration). These persisting symptoms negatively influence patient daily activities as postconcussion syndrome (PCS). Second-impact syndrome (SIS) is a very rare but usually fatal condition and occurs when repeated brain injuries lead to a catastrophic diffuse brain swelling. There is no scientific evidence on the incidence and risk of SIS. Chronic traumatic encephalopathy (CTE) is a progressive degenerative disease of the brain found in patients with a history of repetitive brain trauma. CTE presents with behavioural, cognitive, and motor symptoms. The literature to date lacks prospective epidemiological studies of the incidence of CTE. In recent medical literature, there is a description of 110 athletes with postmortem diagnosis of CTE (Tab. 1, Ref. 37). PMID:26810165

    Eplerenone (Inspra®) is a selective mineralocorticoid receptor antagonist (MRA). In the EU, it is approved for use (in addition to standard optimal therapy) to reduce the risk of cardiovascular (CV) mortality and morbidity in adult patients with chronic systolic heart failure (HF) and mild symptoms. This article reviews the efficacy and tolerability of eplerenone in this indication and briefly summarizes its pharmacology. In the EMPHASIS-HF study, relative to placebo, the addition of eplerenone to optimal background therapy significantly reduced the risk of death from CV causes or hospitalization for HF in patients with chronic systolic HF and mild symptoms. Benefits of eplerenone therapy over placebo were also observed in several secondary outcomes, including: death from any cause or hospitalization for HF; death from any cause; hospitalization for any reason; or hospitalization for HF. Eplerenone was generally well tolerated in this study, with the most frequent adverse event being hyperkalaemia, which is a known adverse event of the drug class. Sexual adverse events (e.g. gynecomastia) occurred in <1 % of eplerenone recipients, reflecting the selectivity of eplerenone for mineralocorticoid receptors. Based on these results, European guidelines have been updated and recommend the use of an MRA to reduce the risk of HF hospitalization and premature death in all patients with persisting symptoms (New York Heart Association class II-IV) and a left-ventricular ejection fraction of ≤35 %, despite treatment with ACE inhibitor (or an angiotensin receptor blocker if an ACE inhibitor is not tolerated) and a β-blocker.

    Vertigo, was provoked and right torsional up-beat nystagmus was observed in a 47-year-old patient when she was placed into the right Hallpike-Dix test position using infrared goggle technology. The clinical diagnosis was benign paroxysmal positional vertigo (BPPV), specifically right posterior canalithiasis, resulting from a mild traumatic brain injury (TBI) suffered approximately six-months earlier. Previous medical consultations did not include vestibular system examination, and Meclizine was prescribed to suppress her chief complaint of vertigo. Ultimately, the patient was successfully managed by performing two canalith repositioning maneuvers during a single clinical session. The patient reported 100% resolution of symptoms upon reexamination the following day, and the Hallpike-Dix test was negative. Continued symptom resolution was subjectively reported 10 days postintervention via telephone consultation. This case report supports previous publications concerning the presence of BPPV following TBI and the need for inclusion of vestibular system examination during medical consultation. PMID:19826635

    Background Caregivers of patients with mild cognitive impairment (MCI) need similar levels of support services as Alzheimer’s disease (AD) caregivers, but it is unclear if this translates to increased caregiver burden. Methods 135 participants and their caregivers (40 MCI, 55 AD and 40 normal controls, NC) completed questionnaires, and the patients were administered neuropsychological tests. Results The MCI caregivers reported significantly more overall caregiving burden than the NC, but less than the AD. They showed similar levels of emotional, physical and social burden as the AD caregivers. Among the MCI caregivers, the neuropsychiatric symptoms and executive functioning of the patients were related to a greater burden, and the caregivers with a greater burden reported lower life satisfaction and social support, and a greater need for support services. Conclusion These results indicate that MCI caregivers are at increased risk for caregiver stress, and they require enhanced assistance and/or education in caring for their loved ones. PMID:23128102

    Persons with mild Alzheimer’s disease (AD) have significant deficits in financial abilities. This study examined the relationship between brain structure volumes, cognition, and financial capacity in patients with mild AD. Sixteen mild AD patients and 16 older adult comparisons completed the Financial Capacity Instrument (FCI), a psychometric measure of financial abilities, and also underwent magnetic resonance imaging (MRI) to obtain volumes of the bilateral hippocampi, angular gyri, precunei, and medial and dorsolateral frontal cortices. Mild AD patients performed significantly below comparisons on the FCI and had significantly smaller hippocampi. Among mild AD patients, FCI performance was moderately correlated with frontal (medial and dorsolateral frontal cortex) and posterior (angular gyri and precunei) cortical volumes. Stepwise regression demonstrated that medial frontal cortex volume predicted FCI score. The relationship between medial frontal cortex volume and overall FCI score was partially mediated by two measures of simple attention (DRS Attention, DRS Construction). The findings suggest that medial frontal cortex atrophy and associated declines in simple attention play an increasingly important role in declining financial skills in patients with mild AD.

    Small asymptomatic cysts of the pineal gland represent a common incidental finding in adults undergoing computerized tomography or magnetic resonance (MR) imaging or at postmortem examination. In contrast, large symptomatic pineal cysts are rare, being limited to individual case reports or small series. The authors have reviewed 24 cases of large pineal cysts. The mean patient age at presentation was 28.7 years (range 15 to 46 years); 18 were female and six male. Presenting features in 20 symptomatic cases included: headache in 19; nausea and/or vomiting in seven; papilledema in five; visual disturbances in five (diplopia in three, "blurred vision" in two, and unilateral partial oculomotor nerve palsy in one); Parinaud's syndrome in two; hemiparesis in one; hemisensory aberration in one; and seizures in one. Four lesions were discovered incidentally. Magnetic resonance imaging typically demonstrated a 0.8- to 3.0-cm diameter mass (mean 1.7 cm) with homogeneous decreased signal intensity on T1-weighted images, increased signal intensity on T2-weighted images, and a distinct margin. Hydrocephalus was present in eight cases. The cysts were surgically excised via an infratentorial/supracerebellar approach (23 cases) or stereotactically biopsied (one case). Histological examination revealed a cyst wall 0.5 to 2.0 mm thick comprised of three layers: an outer fibrous layer, a middle layer of pineal parenchymal cells with variable calcification, and an inner layer of hypocellular glial tissue often exhibiting Rosenthal fibers and/or granular bodies. Evidence of prior hemorrhage, mild astrocytic degenerative atypia, and disorganization of pineal parenchyma were often present. Postoperative follow-up review in all 24 cases (range 3 months to 10 years) revealed no complications in 21, mild ocular movement deficit in one, gradually resolving Parinaud's syndrome in one, and radiographic evidence of a postoperative venous infarct of the superior cerebellum with ataxia of 1 week

    Effective treatment of diabetic sensorimotor polyneuropathy remains a challenge. To assess the efficacy and safety of α-lipoic acid (ALA) over 20 weeks, we conducted a multicenter randomized withdrawal open-label study, in which 45 patients with type 2 diabetes and symptomatic polyneuropathy were initially treated with ALA (600 mg tid) for 4 weeks (phase 1). Subsequently, responders were randomized to receive ALA (600 mg qd; n = 16) or to ALA withdrawal (n = 17) for 16 weeks (phase 2). During phase 1, the Total Symptom Score (TSS) decreased from 8.9 ± 1.8 points to 3.46 ± 2.0 points. During phase 2, TSS improved from 3.7 ± 1.9 points to 2.5 ± 2.5 points in the ALA treated group (p < 0.05) and remained unchanged in the ALA withdrawal group. The use of analgesic rescue medication was higher in the ALA withdrawal group than ALA treated group (p < 0.05). In conclusion, in type 2 diabetic patients with symptomatic polyneuropathy who responded to initial 4-week high-dose (600 mg tid) administration of ALA, subsequent treatment with ALA (600 mg qd) over 16 weeks improved neuropathic symptoms, whereas ALA withdrawal was associated with a higher use of rescue analgesic drugs.

    Mild cognitive impairment (MCI) was recognized as the prodromal stage of Alzheimer's disease (AD). Recent researches have shown that cognitive and memory decline in AD patients is coupled with losses of small-world attributes. However, few studies pay attention to the characteristics of the whole brain networks in MCI patients. In the present study, we investigated the topological properties of the whole brain networks utilizing graph theoretical approaches in 16 MCI patients, compared with 18 age-matched healthy subjects as a control. Both MCI patients and normal controls showed small-world architectures, with large clustering coefficients and short characteristic path lengths. We detected significantly longer characteristic path length in MCI patients compared with normal controls at the low sparsity. The longer characteristic path lengths in MCI indicated disrupted information processing among distant brain regions. Compared with normal controls, MCI patients showed decreased nodal centrality in the brain areas of the angular gyrus, heschl gyrus, hippocampus and superior parietal gyrus, while increased nodal centrality in the calcarine, inferior occipital gyrus and superior frontal gyrus. These changes in nodal centrality suggested a widespread rewiring in MCI patients, which may be an integrated reflection of reorganization of the brain networks accompanied with the cognitive decline. Our findings may be helpful for further understanding the pathological mechanisms of MCI.

    Posttraumatic migraine may represent an important subtype of headache among the traumatic brain injury (TBI) population and is associated with increased recovery times. However, it is underdiagnosed in patients with mild traumatic brain injury (mTBI). This study examined the effectiveness of the self-administered Nine-Item Screener (Nine-Item Screener-SA), the Headache Impact Test- 6 (HIT-6), the 3-Item Migraine Screener, and the Rivermead Post-Concussion Questionnaire (RPQ) at discriminating between mTBI patients with (n = 23) and without (n = 20) migraines. The Nine-Item Screener demonstrated significant differences between migraine patients with and without migraine on nearly every question, especially on Question 9 (disability), sensitivity: 0.95 and specificity: 0.65 (95% CI, 0.64-0.90). The HIT-6 demonstrated significant differences between migraine and no-migraine patients on disability and pain severity, with disability having a sensitivity of 0.70 and specificity of 0.75 (95% CI, 0.54-0.83). Only Question 3 of the 3-Item ID Migraine Screener (photosensitivity) showed significant differences between migraine and no-migraine patients, sensitivity: 0.84 and specificity: 0.55 (CI, 0.52-0.82). The RPQ did not reveal greater symptoms in migraine patients compared with those without. Among headache measures, the Nine-Item Screener-SA best differentiated between mTBI patients with and without migraine. Disability may best identify migraine sufferers among the TBI population.

    The purpose of this study was to compare 104 patients with acute uncomplicated mild traumatic brain injury (MTBI) to a sample of 104 patients from an inpatient substance abuse program to determine whether these patients could be differentiated by their pattern of relative cognitive strengths and weaknesses. Patients were matched on age, education, and gender. Eight cognitive measures were used that included tests of attention, memory, and processing speed. There were no statistically significant differences between the two groups on any of the cognitive measures. Using a two-step cluster analysis procedure (i.e., hierarchical and k-means analyses), seven common profiles were identified. There was no significant difference in the proportions of patients from the MTBI or substance abuse group in each of the seven profiles. These results show that patients with uncomplicated MTBIs could not be reliably differentiated from patients with substance abuse problems on these cognitive measures. This is of particular concern for clinicians evaluating the neuropsychological effects of MTBI in individuals with a comorbid history of substance abuse. PMID:17853134

    In the present work we analyzed forward saccades of thirty five elderly subjects (Controls) and of thirty five mild Alzheimer's disease (AD) during reading regular and high-predictable sentences. While they read, their eye movements were recorded. The pattern of forward saccade amplitudes as a function of word predictability was clearly longer in Controls. Our results suggest that Controls might use stored information of words for enhancing their reading performance. Further, cloze predictability increased outgoing saccades amplitudes, as this increase stronger in high-predictable sentences. Quite the contrary, patients with mild AD evidenced reduced forward saccades even at early stages of the disease. This reduction might reveal impairments in brain areas such as those corresponding to working memory, memory retrieval, and semantic memory functions that are already present at early stages of AD. Our findings might be relevant for expanding the options for the early detection and monitoring of in the early stages of AD. Furthermore, eye movements during reading could provide a new tool for measuring a drug's impact on patient's behavior. PMID:26228165

    Performance on tasks that require saccadic inhibition declines with age and altered inhibitory functioning has also been reported in patients with Alzheimer's disease. Although mild cognitive impairment (MCI) is assumed to be a high-risk factor for conversion to AD, little is known about changes in saccadic inhibition and its neural correlates in this condition. Our study determined whether the neural activation associated with saccadic inhibition is altered in persons with amnestic mild cognitive impairment (aMCI). Functional magnetic resonance imaging (fMRI) revealed decreased activation in parietal lobe in healthy elderly persons compared to young persons and decreased activation in frontal eye fields in aMCI patients compared to healthy elderly persons during the execution of anti-saccades. These results illustrate that the decline in inhibitory functions is associated with impaired frontal activation in aMCI. This alteration in function might reflect early manifestations of AD and provide new insights in the neural activation changes that occur in pathological ageing. PMID:23898312

    Aim. To asses both choroidal thickness differences among Alzheimer's type dementia (ATD) patients, mild cognitive impairment (MCI) patients, and healthy control (C) subjects and choroidal thickness relationships with cognitive performance. Methods. A total of 246 eyes of 123 people (41 ATD, 38 MCI, and 44 healthy C subjects) were included in this study. Complete ophthalmological and neurological examination was performed in all subjects. Choroidal thicknesses (CT) were measured at seven locations: the fovea, 500-1500-3000 μm temporal and 500-1500-3000 μm nasal to the fovea by enhanced depth imaging optical coherence tomography (EDI-OCT). Detailed neurological examination including mini mental state examination (MMSE) test which evaluates the cognitive function was applied to all participants. Results. The ages and genders of all participants were similar in all groups. Compared with healthy C subjects, the CT measurements at all regions were significantly thinner both in patients with ATD and in patients with MCI than in healthy C subjects (p < 0.05). The MMSE scores were significantly different among ATD patients, MCI patients, and healthy C subjects. They were 19.3 ± 1.8, 24.8 ± 0.9, and 27.6 ± 1.2 in ATD, MCI, and healthy controls, respectively (p < 0.001). There were also significant correlation between MMSE score and choroidal thickness at each location (p < 0.05). Conclusions. CT was reduced in ATD patients and MCI patients. Since vascular structures were affected in ATD patients and MCI patients, they had thin CT. Besides CT was correlated with degree of cognitive impairment. Therefore CT may be a new biomarker in diagnosis and follow-up of MCI and ATD patients. PMID:26925259

    This letter to the editor describes the case of a 42 year old man with mild traumatic brain injury and multiple neuropsychiatric symptoms which persisted for a few years after the injury. Initial CT scans and MRI scans of the brain showed no signs of atrophy. Brain volume was measured using NeuroQuant®, an FDA-approved, commercially available software method. Volumetric cross-sectional (one point in time) analysis also showed no atrophy. However, volumetric longitudinal (two points in time) analysis showed progressive atrophy in several brain regions. This case illustrated in a single patient the principle discovered in multiple previous group studies, namely that the longitudinal design is more powerful than the cross-sectional design for finding atrophy in patients with traumatic brain injury.

    Recent findings suggest that Alzheimer's disease (AD) is a disconnection syndrome characterized by abnormalities in large-scale networks. However, the alterations that occur in network topology during the prodromal stages of AD, particularly in patients with stable mild cognitive impairment (MCI) and those that show a slow or faster progression to dementia, are still poorly understood. In this study, we used graph theory to assess the organization of structural MRI networks in stable MCI (sMCI) subjects, late MCI converters (lMCIc), early MCI converters (eMCIc), and AD patients from 2 large multicenter cohorts: ADNI and AddNeuroMed. Our findings showed an abnormal global network organization in all patient groups, as reflected by an increased path length, reduced transitivity, and increased modularity compared with controls. In addition, lMCIc, eMCIc, and AD patients showed a decreased path length and mean clustering compared with the sMCI group. At the local level, there were nodal clustering decreases mostly in AD patients, while the nodal closeness centrality detected abnormalities across all patient groups, showing overlapping changes in the hippocampi and amygdala and nonoverlapping changes in parietal, entorhinal, and orbitofrontal regions. These findings suggest that the prodromal and clinical stages of AD are associated with an abnormal network topology. PMID:27178195

    Objective To investigate the sleep state of mild stroke patients and relationship between sleep disturbance and functional status. Methods A total of 80 acute stroke patients were enrolled in this study. The criteria for inclusion in the study was as following: 1) first stroke, 2) cognitive function preserved enough to perform the test (Mini Mental State Examination ≥24), 3) good functional levels (Modified Rankin Scale ≤3), 4) upper extremity motor function preserved enough to perform occupational tests (hand strength test, Purdue pegboard test, 9-hole peg test, and Medical Research Council score ≥3), and 5) less than 2 weeks between the stroke and the assessment. Quality of sleep was assessed by using Pittsburg Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), and Stanford Sleepiness Scale (SSS). Activities of daily living was assessed by using the Modified Barthel Index (MBI) and depressed mood was assessed by using the Beck Depression Inventory (BDI). Gross and fine motor function of the upper extremity was assessed by using hand strength test (Jamar dynamometer), Purdue pegboard test, and the 9-hole peg test. Results The results of the occupational assessment were fine in the good sleepers. The PSQI, ESS, and ISI were correlated with some of the assessment tools (BDI, MBI, Purdue pegboard, 9-hole peg, and hand strength). Conclusion In conclusion, this study emphasizes that sleep disturbance can affect the functional status in mild acute stroke patients. Therefore, clinicians must consider sleep status in stroke patients and need to work to control it. PMID:26361590

    OBJECTIVE: To summarize the effect of mild hypothermia on function of the organs in patients with multiple organ dysfunction syndrome after cardiopulmonary bypass surgery. METHODS: The patients were randomly divided into two groups, northermia group (n=71) and hypothermia group (n=89). We immediately began cooling the hypothermia group when test results showed multiple organ dysfunction syndrome, meanwhile all patients of two groups were drawn blood to test blood gas, liver and kidney function, blood coagulation function, and evaluated the cardiac function using echocardiography from 12 to 36 hours. We compared the difference of intra-aortic balloon pump, extracorporeal membrane oxygenation rate and mortality within one month after intensive care unit admission. RESULTS: Among the 160 patients, 36 died, 10 (11.24%) patients were from the hypothermia group and 26 (36.6%) from the northermia group (P <0.05). In northermia group, 45 (63.38%) patients used intra-aortic balloon pump and 4 (5.63%), extracorporeal membrane oxygenation; in hypothermia group, 35 (39.32%) patients used intra-aortic balloon pump and 2 (2.25%), extracorporeal membrane oxygenation( P <0.05). The patients' heart rate decreased significantly in the hypothermia group. The heart rate of hypothermia group is significantly slower than the northermia group at the 36th hour (P <0.05). But the mean arterial pressure of hypothermia group is significantly higher than the northermia group at the 36th hour (P <0.05). In hypothermia group, PO2, SvO2 and lactate were improved significantly compared to pre-cooling (P <0.05), and they were significantly better than the northermia group at the 36th hour (P <0.05%). Prothrombin time and activated partial thromboplastin time have no significantly difference between the two groups (P >0.05). But the platelet count has significantly difference between the two groups at the 36th hour (P <0.05). The aspartate transaminase, alanine transaminase and creatinine were

    Systematic capture of the patient perspective can inform the development of new cancer therapies. Patient-reported outcomes (PROs) are commonly included in cancer clinical trials; however, there is heterogeneity in the constructs, measures, and analytic approaches that have been used making these endpoints challenging to interpret. There is renewed effort to identify rigorous methods to obtain high-quality and informative PRO data from cancer clinical trials. In this setting, PROs are used to address specific research objectives, and an important objective that spans the product development life cycle is the assessment of safety and tolerability. The U.S. Food and Drug Administration's (FDA) Office of Hematology and Oncology Products (OHOP) has identified symptomatic adverse events (AEs) as a central PRO concept, and a systematic assessment of patient-reported symptomatic AEs can provide data to complement clinician reporting. The National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) is being evaluated by multiple stakeholders, including the FDA, and is considered a promising tool to provide a standard yet flexible method to assess symptomatic AEs from the patient perspective. In this article, we briefly review the FDA OHOP's perspective on PROs in cancer trials submitted to the FDA and focus on the assessment of symptomatic AEs using PRO-CTCAE. We conclude by discussing further work that must be done to broaden the use of PRO-CTCAE as a method to provide patient-centered data that can complement existing safety and tolerability assessments across cancer clinical trials.

    In the present work we analyzed the effect of contextual word predictability on the eye movement behavior of patients with mild Alzheimer disease (AD) compared to age-matched controls, by using the eyetracking technique and lineal mixed models. Twenty AD patients and 40 age-matched controls participated in the study. We first evaluated gaze duration during reading low and highly predictable sentences. AD patients showed an increase in gaze duration, compared to controls, both in sentences of low or high predictability. In controls, highly predictable sentences led to shorter gaze durations; by contrary, AD patients showed similar gaze durations in both types of sentences. Similarly, gaze duration in controls was affected by the cloze predictability of word N and N+1, whereas it was the same in AD patients. In contrast, the effects of word frequency and word length were similar in controls and AD patients. Our results imply that contextual-word predictability, whose processing is proposed to require memory retrieval, facilitated reading behavior in healthy subjects, but this facilitation was lost in early AD patients. This loss might reveal impairments in brain areas such as those corresponding to working memory, memory retrieval, and semantic memory functions that are already present at early stages of AD. In contrast, word frequency and length processing might require less complex mechanisms, which were still retained by AD patients. To the best of our knowledge, this is the first study measuring how patients with early AD process well-defined words embedded in sentences of high and low predictability. Evaluation of the resulting changes in eye movement behavior might provide a useful tool for a more precise early diagnosis of AD.

    Amnestic mild cognitive impairment (MCI) has been conceptualized as a transitional stage between healthy aging and Alzheimer’s disease. Thus, understanding emotional face recognition deficit in patients with amnestic MCI could be useful in determining progression of amnestic MCI. The purpose of this study was to investigate the features of emotional face processing in amnestic MCI by using event-related potentials (ERPs). Patients with amnestic MCI and healthy controls performed a face recognition task, giving old/new responses to previously studied and novel faces with different emotional messages as the stimulus material. Using the learning-recognition paradigm, the experiments were divided into two steps, ie, a learning phase and a test phase. ERPs were analyzed on electroencephalographic recordings. The behavior data indicated high emotion classification accuracy for patients with amnestic MCI and for healthy controls. The mean percentage of correct classifications was 81.19% for patients with amnestic MCI and 96.46% for controls. Our ERP data suggest that patients with amnestic MCI were still be able to undertake personalizing processing for negative faces, but not for neutral or positive faces, in the early frontal processing stage. In the early time window, no differences in frontal old/new effect were found between patients with amnestic MCI and normal controls. However, in the late time window, the three types of stimuli did not elicit any old/new parietal effects in patients with amnestic MCI, suggesting their recollection was impaired. This impairment may be closely associated with amnestic MCI disease. We conclude from our data that face recognition processing and emotional memory is impaired in patients with amnestic MCI. Such damage mainly occurred in the early coding stages. In addition, we found that patients with amnestic MCI had difficulty in post-processing of positive and neutral facial emotions. PMID:26347065

    This internal representation of movement of part(s) of the body is involved during Implicit Motor Imagery tasks (IMI); the same representations are employed in the laterality judgment task. Few studies have looked at the consequences of aging, Alzheimer's disease (AD) and mild cognitive impairment (MCI) on the processes of motor preparation but none showed evidence of an alteration of action representation in patient with amnestic MCI. In the present study, the IMI task was used to assess the action representation abilities in MCI patients and healthy counterparts. A total of 24 elderly participants aged between 65 and 90 years old (12 women, 73.4 ± 6 years, mean ± S.D.) were recruited: 12 patients with MCI (MCI group) and 12 healthy aged adults (HAA group). The results showed that MCI patients have significantly a greater response time (RT) than HAA subjects only in IMI task and more precisely when performing their mental rotation at the challenging conditions. Furthermore, the IMI task related to the non-dominant hand induced a significant increase of RT only in MCI subjects. At the light of these results, we assume that MCI patients are able to engage themselves in IMI processes, still showing a compelling impairment of this mental ability across its complexity.

    Carpal coalition is an uncommon congenital abnormality that arises from incomplete cavitation of the common cartilaginous precursor that forms the carpal bones. When carpal coalition is discovered, it is typically an asymptomatic incidental radiographic finding, and is often bilateral. We present a case of symptomatic unilateral carpal coalition of the scaphotrapezial joint, which was treated by excising the fibrous coalition and placing an interposition fat graft. This treatment was effective in alleviating the patient's symptoms.

    It is well known that flow patterns at the anastomosis of coronary artery bypass graft (CABG) are complex and may affect the long-term patency. Various attempts at optimal designs of anastomosis have not improved long-term patency. Here, we hypothesize that mild anastomotic stenosis (area stenosis of about 40–60%) may be adaptive to enhance the hemodynamic conditions, which may contribute to slower progression of atherosclerosis. We further hypothesize that proximal/distal sites to the stenosis have converse changes that may be a risk factor for the diffuse expansion of atherosclerosis from the site of stenosis. Twelve (12) patient-specific models with various stenotic degrees were extracted from computed tomography images using a validated segmentation software package. A 3-D finite element model was used to compute flow patterns including wall shear stress (WSS) and its spatial and temporal gradients (WSS gradient, WSSG, and oscillatory shear index, OSI). The flow simulations showed that mild anastomotic stenosis significantly increased WSS (>15 dynes⋅cm−2) and decreased OSI (<0.02) to result in a more uniform distribution of hemodynamic parameters inside anastomosis albeit proximal/distal sites to the stenosis have a decrease of WSS (<4 dynes⋅cm−2). These findings have significant implications for graft adaptation and long-term patency. PMID:24058488

    Intracranial atherosclerotic disease is a common cause of stroke worldwide, causing approximately 10 % of strokes in the USA and up to 50 % in Asian populations. Recurrent stroke risks are particularly high in those with a stenosis of 70 % or more and a recent transient ischemic attack or stroke. Warfarin has been associated with higher major hemorrhage rates and no reduction of recurrent stroke compared to aspirin in patients with symptomatic intracranial stenosis. After early trials showed the feasibility of stenting, two randomized trials compared stenting plus medical management to medical management alone in symptomatic intracranial stenosis. Stenting was linked with increased risk and showed no benefit in any subpopulation of patients. Aggressive medical management in the Stenting and Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) trial was associated with half the risk of stroke compared to that in similar patients in a previous symptomatic intracranial stenosis trial after adjustment of confounding characteristics. Aggressive medical management comprises risk factor control, including a target systolic blood pressure <140 mmHg, a low density lipoprotein <70 mg/dL, hemoglobin A1C <7.0 %, and lifestyle management that incorporates exercise, smoking cessation and weight management, and the use of antithrombotics.

    It is well recognized that mitochondrial dysfunction contributes to neurodegeneration occurring in Alzheimer's disease (AD). However, evidences of mitochondrial defects in AD peripheral cells are still inconclusive. Here, some mitochondrial-encoded and nuclear-encoded proteins, involved in maintaining the correct mitochondria machine, were investigated in terms of protein expression and enzymatic activity in peripheral blood mononuclear cells (PBMCs) isolated from AD and Mild Cognitive Impairment (MCI) patients and healthy subjects. In addition mitochondrial DNA copy number was measured by real time PCR. We found some differences and some similarities between AD and MCI patients when compared with healthy subjects. For example, cytochrome C and cytochrome B were decreased in AD, while MCI showed only a statistical reduction of cytochrome C. On the other hand, both AD and MCI blood cells exhibited highly nitrated MnSOD, index of a prooxidant environment inside the mitochondria. TFAM, a regulator of mitochondrial genome replication and transcription, was decreased in both AD and MCI patients' blood cells. Moreover also the mitochondrial DNA amount was reduced in PBMCs from both patient groups. In conclusion these data confirmed peripheral mitochondria impairment in AD and demonstrated that TFAM and mtDNA amount reduction could be two features of early events occurring in AD pathogenesis.

    Our objective was to determine the probability threshold for recurrent symptoms at which elective cholecystectomy compared to observation in older patients with symptomatic cholelithiasis is the more effective and cost-effective option. We built a decision model of elective cholecystectomy versus observation in patients >65 presenting with initial episodes of symptomatic cholelithiasis that did not require initial hospitalization or cholecystectomy. Probabilities for subsequent hospitalization, emergency cholecystectomy, and perioperative complications were based on previously published probabilities from a 5 % national sample of Medicare patients. Costs were estimated from Medicare reimbursements and from the Healthcare Cost and Utilization Project. Utilities (quality-adjusted life years, QALYs) were obtained from established literature estimates. Elective cholecystectomy compared to observation in all patients was associated with lower effectiveness (-0.10 QALYs) and had an increased cost of $3,422.83 per patient at 2-year follow-up. Elective cholecystectomy became the more effective option when the likelihood for continued symptoms exceeded 45.3 %. Elective cholecystectomy was both more effective and less costly when the probability for continued symptoms exceeded 82.7 %. An individualized shared decision-making strategy based on these data can increase elective cholecystectomy rates in patients at high risk for recurrent symptoms and minimize unnecessary cholecystectomy for patients unlikely to benefit.

    Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious and hemorrhagic disease recently described in China and western Japan. A 71-year-old healthy Japanese woman noticed a tick biting her after harvesting in an orchard and removed it herself. She developed diarrhea, anorexia, and chills eight days later. Because these symptoms continued, she visited a primary care physician 6 days after the onset. Laboratory data revealed thrombocytopenia, leukocytopenia, and elevated liver enzymes. She was then referred to our hospital. Although not completely fulfilling the diagnostic criteria used in a retrospective study in Japan, SFTS was suspected, and we detected SFTS virus in the patient's blood using RT-PCR. However, she recovered without intensive treatment and severe complications 13 days after the onset. In this report, we present a mild clinical course of SFTS virus infection in Japan in detail.

    Post-traumatic amnesia (PTA) is an acute characteristic of traumatic brain injury (TBI) and the duration of PTA is commonly used to estimate the severity of brain injury. In the context of mild traumatic brain injury (MTBI), PTA is an essential part of the routine clinical assessment. Macroscopic lesions in temporal lobes, especially hippocampal regions, are thought to be connected to memory loss. However, conventional neuroimaging has failed to reveal neuropathological correlates of PTA in MTBI. Texture analysis (TA) is an image analysis technique that quantifies the minor MRI signal changes among image pixels and, therefore, the variations in intensity patterns within the image. The objective of this work was to apply the TA technique to MR images of MTBI patients and control subjects, and to assess the microstructural damage in medial temporal lobes of patients with MTBI with definite PTA. TA was performed for fluid-attenuated inversion recovery (FLAIR) images of 50 MTBI patients and 50 age- and gender-matched controls in the regions of the amygdala, hippocampus, and thalamus. It was hypothesized that 1) there would be statistically significant differences in TA parameters between patients with MTBIs and controls, and 2) the duration of PTA would be related to TA parameters in patients with MTBI. No significant textural differences were observed between patients and controls in the regions of interest (p>0.01). No textural features were observed to correlate with the duration of PTA. Subgroup analyses were conducted on patients with PTA of>1 h, (n=33) and compared the four TA parameters to the age- and gender-matched controls (n=33). The findings were similar. This study did not reveal significant textural changes in medial temporal structures that could be related to the duration of PTA.

    Introduction Although there are approximately 1.1 million case presentations of mild traumatic brain injury (mTBI) in the emergency department (ED) each year, little data is available to clinicians to identify patients who are at risk for poor outcomes, including 72-hour ED return after discharge. An understanding of patients at risk for ED return visits during the hyperacute phase following head injury would allow ED providers to develop clinical interventions that reduce its occurrence and improve outcomes. Methods This institutional review board-approved consecutive cohort study collected injury and outcome variables on adults with the purpose of identifying positive predictors for 72-hour ED return visits in mTBI patients. Results Of 2,787 mTBI patients, 145 (5%) returned unexpectedly to the ED within 72 hours of hospital discharge. Positive predictors for ED return visits included being male (p=0.0298), being black (p=0.0456), having a lower prehospital Glasgow Coma Score (p=0.0335), suffering the injury due to a motor vehicle collision (p=0.0065), or having a bleed on head computed tomography (CT) (p=0.0334). ED return visits were not significantly associated with age, fracture on head CT, or symptomology following head trauma. Patients with return visits most commonly reported post-concussion syndrome (43.1%), pain (18.7%), and recall for further clinical evaluation (14.6%) as the reason for return. Of the 124 patients who returned to the ED within 72 hours, one out of five were admitted to the hospital for further care, with five requiring intensive care unit stays and four undergoing neurosurgery. Conclusion Approximately 5% of adult patients who present to the ED for mTBI will return within 72 hours of discharge for further care. Clinicians should identify at-risk individuals during their initial visits and attempt to provide anticipatory guidance when possible. PMID:25987933

    Background: Keratoconus is a contraindication for photorefractive keratectomy (PRK). In the recent decade, some efforts have been made to perform PRK in patients with keratoconus whose corneas are stable naturally or by doing corneal collagen crosslinking. These studies have suggested residual central corneal thickness (CCT) ≥450 μm. Aims: The aim was to evaluate the long-term outcomes of PRK in patients with mild to moderate keratoconus in patients older than 40 with residual CCT ≥ 400 μm. Settings and Design: This prospective study was conducted in our Cornea Research Center, Mashhad, Iran. Materials and Methods: Patients over 40 years old, with a grade I/II keratoconus without progression in the last 2 years were recruited. Patients with a predicted postoperative CCT < 400 μm were excluded. PRK with tissue saving protocol was performed with Tecnolas 217 Z. Mitomycin-C was applied after ablation. The final endpoints were refraction parameters the last follow-up visit (mean: 35 months). Paired t-test and Chi-square were used for analysis. Results: A total of 38 eyes of 21 patients were studied; 20 eyes (52.6%) with a grade I and 18 eyes (47.4%) with grade II keratoconus. The mean uncorrected visual acuity, best corrected visual acuity (BCVA), spherical equivalent, cylindrical power and keratometric readings were significantly improved at the final endpoint compared to preoperation measurements (P < 0.001). Two eyes (5%) lost two lines of BCVA at the final visit. No case of ectasia occurred during the follow-up course. Conclusions: PRK did not induce keratoconus progression in patients older than 40 with a grade I/II keratoconus. Residual CCT ≥ 450 μm seems to be sufficient to prevent the ectasia. PMID:25827548

    Objective To determine the frequency of survival, stroke, atrial fibrillation, structural valve deterioration, and length of hospital stay after surgical replacement of an aortic valve (SAVR) with a bioprosthetic valve in patients with severe symptomatic aortic stenosis. Design Systematic review and meta-analysis of observational studies. Data sources Medline, Embase, PubMed (non-Medline records only), Cochrane Database of Systematic Reviews, and Cochrane CENTRAL from 2002 to June 2016. Study selection Eligible observational studies followed patients after SAVR with a bioprosthetic valve for at least two years. Methods Reviewers, independently and in duplicate, evaluated study eligibility, extracted data, and assessed risk of bias for patient important outcomes. We used the GRADE system to quantify absolute effects and quality of evidence. Published survival curves provided data for survival and freedom from structural valve deterioration, and random effect models provided the framework for estimates of pooled incidence rates of stroke, atrial fibrillation, and length of hospital stay. Results In patients undergoing SAVR with a bioprosthetic valve, median survival was 16 years in those aged 65 or less, 12 years in those aged 65 to 75, seven years in those aged 75 to 85, and six years in those aged more than 85. The incidence rate of stroke was 0.25 per 100 patient years (95% confidence interval 0.06 to 0.54) and atrial fibrillation 2.90 per 100 patient years (1.78 to 4.79). Post-SAVR, freedom from structural valve deterioration was 94.0% at 10 years, 81.7% at 15 years, and 52% at 20 years, and mean length of hospital stay was 12 days (95% confidence interval 9 to 15). Conclusion Patients with severe symptomatic aortic stenosis undergoing SAVR with a bioprosthetic valve can expect only slightly lower survival than those without aortic stenosis, and a low incidence of stroke and, up to 10 years, of structural valve deterioration.

    Summary Background there is only a paucity of studies dealing with bone remodeling within the tunnels after anterior cruciate ligament (ACL) reconstruction. The objective of this study was to evaluate the influence of tendon graft type and surgical fixation technique on bone tunnel remodeling in patients with symptomatic knees after ACL reconstruction. Methods in a retrospective study 99mTc-HDP bone tracer uptake (BTU) in SPECT/CT of 57 knees with symptoms of pain and/or instability after ACL reconstruction was investigated. All 57 knees were subdivided according their anatomy (femur and tibia), fixation (articular versus extra-articular fixation) and graft types into eight groups: femoral-articular versus extra-articular fixation using bone-patellar tendon-bone (BPTB) and hamstring autografts; tibial-articular versus extra-articular fixation using patellar tendon and hamstring autografts; BTU grading for each area of the localisation scheme were recorded. Tunnel diameter and length was measured in the CT scans. Results BTU was higher for the articular fixation in the femur and for the extra-articular fixation in the tibial tunnel. Patellar tendon graft fixation showed a significantly higher BTU in the superior-lateral and posterior-central area of the tibia, meaning the areas of the tibial tunnel near the entrance into the joint. Tunnel enlargement correlated significantly with increased BTU (p<0.05). Conclusion assessment of in vivo bone tunnel remodelling in symptomatic patients after ACL reconstruction revealed different patterns of BTU with regards to graft and fixation method. PMID:26958543

    Benefits of triple therapy with a long-acting muscarinic antagonist (LAMA), added to inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA), have been demonstrated. Limited data assessing the efficacy of the LAMA umeclidinium (UMEC) added to ICS/LABA are available. The aim of this study is to evaluate the efficacy and safety of UMEC added to ICS/LABAs in patients with moderate-to-very-severe COPD. This is a multicentre, randomised, double-blind, parallel-group study. Patients were symptomatic (modified Medical Research Council Dyspnoea Scale score ⩾2), despite receiving ICS/LABA (fluticasone propionate/salmeterol (FP/SAL, branded) 500/50 mcg, budesonide/formoterol (BD/FOR, branded) 200/6 mcg or 400/12 mcg, or other ICS/LABAs) ⩾30 days before the run-in (7±2 days). Patients were randomised 1:1 to once-daily UMEC 62.5 mcg or placebo (PBO), added to twice-daily open-label ICS/LABA for 12 weeks. Primary end point was trough forced expiratory volume in 1 s (FEV1) at Day 85; secondary end point was weighted mean (WM) 0-6 h FEV1 at Day 84; other end points included COPD Assessment Test (CAT) score and Transition Dyspnoea Index (TDI) score. Adverse events (AEs) were investigated. In the UMEC+ICS/LABA and PBO+ICS/LABA groups, 119 and 117 patients were randomised, respectively. Patients received FP/SAL (40%), BD/FOR (43%) and other ICS/LABAs (17%). UMEC+ICS/LABA resulted in significant improvements in trough FEV1 (Day 85) and in WM 0-6 h FEV1 (Day 84) versus PBO+ICS/LABA (difference: 123 and 148 ml, respectively, both P<0.001). Change from baseline for UMEC+ICS/LABA versus PBO+ICS/LABA was significantly different for CAT score at Day 84 (-1.31, P<0.05), but not for TDI score (0.40, P=0.152). AE incidence was similar with UMEC+ICS/LABA (38%) and PBO+ICS/LABA (42%). UMEC+ICS/LABA improved lung function and CAT score in patients with symptomatic COPD versus PBO+ICS/LABA (ClinicalTrials.gov NCT02257372). PMID:27334739

    Background This study uses a MRI technique, three-dimension pulse continuous arterial spin labeling (3D-PCASL), to measure the patient’s cerebral blood flow (CBF) at the subacute stage of mild traumatic brain injury (MTBI) in order to analyze the relationship between cerebral blood flow and neurocognitive deficits. Objective To provide the relationship between cortical CBF and neuropsychological dysfunction for the subacute MTBI patients. Methods After MTBI, perfusion MR imaging technique (3D-PCASL) measures the CBF of MTBI patients (n = 23) within 1 month and that of normal controls (n = 22) to determine the quantity and location of perfusion defect. The correlation between CBF abnormalities and cognitive deficits was elucidated by combining the results of the neuropsychological tests of the patients. Result We observed a substantial reduction in CBF in the bilateral frontal and left occipital cortex as compared with the normal persons. In addition, there were correlation between post concussive symptoms (including dizziness and simulator sickness) and CBF in the hypoperfused areas. The more severe symptom was correlated with higher CBF in bilateral frontal and left occipital lobes. Conclusion First, this study determined that despite no significant abnormality detected on conventional CT and MRI studies, hypoperfusion was observed in MTBI group using 3D-PCASL technique in subacute stage, which suggested that this approach may increase sensitivity to MTBI. Second, the correlation between CBF and the severity of post concussive symptoms suggested that changes in cerebral hemodynamics may play a role in pathophysiology underlies the symptoms.

    Summary Mild cognitive impairment (MCI) entails a high risk of developing Alzheimer’s dementia. In MCI patients gait impairment, which increases the risk of falls and institutionalization, is an early motor sign. A dual-task (DT) paradigm might improve the observation of this phenomenon. The aim of this study was to investigate motor-cognitive interference in a sample of MCI patients and a group of matched healthy controls submitted to DT conditions. To this end, three different cognitive tasks were used: counting backwards, short story recall and a phonemic fluency task. Overall, the patients, compared with the healthy participants, performed worse on the cognitive tasks and showed some degree of gait impairment. In the DT conditions, both groups showed significant gait disruption independently of the concomitant cognitive task. As regards cognitive performance, counting backwards worsened during dual tasking, while short story recall improved in both groups. Overall, our results suggest that the use of a DT paradigm does not improve the early detection of MCI. Our findings of enhanced story recall during walking might have interesting implications for rehabilitation of memory function. PMID:26214028

    It is well established that oxidative stress plays a key role in the degenerative neuronal death and progression of Alzheimer's disease (AD), although it is not clear if it is the primary triggering event in the pathogenesis of this disorder. Mild cognitive impairment (MCI) is a clinical condition between normal aging and AD, characterized by a memory deficit without loss of general cognitive and functional abilities. We performed this study by a comet assay analysis to evaluate the level of primary and oxidative DNA damage in two groups of MCI and AD patients, compared to healthy controls. Data showed a significantly higher level of primary DNA damage in leukocytes of AD and also of MCI patients compared to control individuals (average: 2.09+/-0.79 and 2.47+/-1.01, respectively for AD and MCI, versus 1.04+/-0.31 in controls). Moreover, the amount of oxidised DNA bases (both purines and pyrimidines) was significatively higher in the two groups of patients (AD and MCI) compared to controls. Our results give a further indication that oxidative stress, at least at the DNA level, is an earlier event in the pathogenesis of AD.

    Studies of incidental category learning support the hypothesis of an implicit prototype-extraction system that is distinct from explicit memory (Smith, 2008). In those studies, patients with explicit-memory impairments due to damage to the medial-temporal lobe performed normally in implicit categorization tasks (Bozoki, Grossman, & Smith, 2006; Knowlton & Squire, 1993). However, alternative interpretations are that (a) even people with impairments to a single memory system have sufficient resources to succeed on the particular categorization tasks that have been tested (Nosofsky & Zaki, 1998; Zaki & Nosofsky, 2001) and (b) working memory can be used at time of test to learn the categories (Palmeri & Flanery, 1999). In the present experiments, patients with amnestic mild cognitive impairment or early Alzheimer's disease were tested in prototype-extraction tasks to examine these possibilities. In a categorization task involving discrete-feature stimuli, the majority of subjects relied on memories for exceedingly few features, even when the task structure strongly encouraged reliance on broad-based prototypes. In a dot-pattern categorization task, even the memory-impaired patients were able to use working memory at time of test to extract the category structure (at least for the stimulus set used in past work). We argue that the results weaken the past case made in favor of a separate system of implicit prototype extraction.

    Objectives The aim of this study was to investigate pathological mechanisms underlying brain tissue alterations in mild cognitive impairment (MCI) using multi-contrast 3 T magnetic resonance imaging (MRI). Methods Forty-two MCI patients and 77 healthy controls (HC) underwent T1/T2* relaxometry as well as Magnetization Transfer (MT) MRI. Between-groups comparisons in MRI metrics were performed using permutation-based tests. Using MRI data, a generalized linear model (GLM) was computed to predict clinical performance and a support-vector machine (SVM) classification was used to classify MCI and HC subjects. Results Multi-parametric MRI data showed microstructural brain alterations in MCI patients vs HC that might be interpreted as: (i) a broad loss of myelin/cellular proteins and tissue microstructure in the hippocampus (p ≤ 0.01) and global white matter (p < 0.05); and (ii) iron accumulation in the pallidus nucleus (p ≤ 0.05). MRI metrics accurately predicted memory and executive performances in patients (p ≤ 0.005). SVM classification reached an accuracy of 75% to separate MCI and HC, and performed best using both volumes and T1/T2*/MT metrics. Conclusion Multi-contrast MRI appears to be a promising approach to infer pathophysiological mechanisms leading to brain tissue alterations in MCI. Likewise, parametric MRI data provide powerful correlates of cognitive deficits and improve automatic disease classification based on morphometric features. PMID:26236628

    Heart failure is a progressive cardiovascular disorder and, in most cases, begins with atherosclerosis and ischemic heart disease. The prognosis of patients with heart failure is poor, even with improvement on the management of all forms of ischemic heart disease. There have been studies on heart failure using a single nutrient or a combination of multiple nutrients. Results are mixed. The aim of this study was to assess the influence of multiple micronutrient supplementation using the quality of life measure on patients with heart failure secondary to ischemic heart disease. This prospective case series followed 12 patients for a period between 3 to 8 months, using the Minnesota Living with Heart Failure Questionnaire (MLHFQ) as the sole outcome measure. The primary outcome was a score change over time between the start and endpoint of treatment. Change in MLHFQ mean total score was 27.08 ± 20.43 and mean symptoms score was 4.67 ± 3.34. Paired t-test showed a difference between baseline and endpoint of treatment (P < 0.001), which was statistically significant. A high dose of multiple micronutrients may have beneficial effects on cardiac function in patients with symptomatic heart failure. This study indicates the need for long-term controlled studies to test the efficacy and safety of this economic approach in managing heart failure.

    Background: The relationship of conventional cardiovascular risk factors (age, gender, ethnicity, diabetes, dyslipidaemia, hypertension, obesity, exercise, and the number of risk factors) to coronary artery calcification (CAC) presence and extent has never before been assessed in a systematic review and meta-analysis. Methods: We included only English language studies that assessed at least three conventional risk factors apart from age, gender, and ethnicity, but excluded studies in which all patients had another confirmed condition such as renal disease. Results: In total, 10 studies, comprising 15,769 patients, were investigated in the systematic review and seven studies, comprising 12,682 patients, were included in the meta-analysis, which demonstrated the importance of diabetes and hypertension as predictors of CAC presence and extent, with age also predicting CAC presence. Male gender, dyslipidaemia, family history of coronary artery disease, obesity, and smoking were overall not predictive of either CAC presence or extent, despite dyslipidaemia being a key risk factor for coronary artery disease (CAD). Conclusion: Diabetes and hypertension consistently predict the presence and extent of CAC in symptomatic patients. PMID:27608015

    Microscopic Colitis (MC) and diarrhea predominant irritable bowel syndrome (IBS-D) has almost similar clinical feature but MC is diagnosed by histologic criteria and IBS is diagnosed by symptom-based criteria. There is ongoing debate about the importance of biopsies from endoscopically normal colonic mucosa in the investigation of patients with IBS-D. Aim of this study was to assess the prevalence of MC in patient with IBS-D and to determine the distribution of MC in the colon. This observational study was conducted in department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2008 to December 2009. Patients were evaluated thoroughly & who meet Rome-II criteria with normal routine laboratory tests, were included in the study. Colonoscopy was done and biopsies were taken from the caecum, transverse colon, descending colon, and rectum. Out of total 60 patients, 22 had Lymphocytic Colitis (LC), 28 had nonspecific microscopic colitis (NSMC) and 10 had irritable bowel syndrome noninflamed (IBSNI). The distribution of LC was restricted to proximal colon in 15 patients, in the left colon in 2 patients and diffuses throughout the colon in 5 patients. There is considerable symptom overlap between the patients of IBS-D and patients with microscopic colitis. Without colonoscopic biopsy from multiple sites, possibility of MC cannot be excluded in patients with IBS-D and it can be said that clinical symptom based criteria for irritable bowel syndrome are not sufficient enough to rule out the diagnosis of microscopic colitis.

    Background Tenofovir (TDF) can cause kidney injury through tubular dysfunction, with or without drop of estimated glomerular filtration rate (eGFR). Whether mild eGFR reductions during treatment should be considered a reason for prompt TDF discontinuation, however, remains unclear. Methods Patients with normal pre-TDF eGFR levels, who had developed mild renal impairment (i.e., two consecutive eGFR results between 89–60 ml/min) on TDF, were observed until onset of chronic kidney disease (CKD), defined as two eGFR<60 ml/min 3 to 6 months apart. Multivariable Poisson regression analysis was used to investigate whether outcome was associated with current and cumulative use of TDF (modeled as time-varying covariates). Results 2023 (29%) out of 6984 patients developed mild renal impairment on TDF. Among them, 191 progressed to CKD. The incidence of CKD did not significantly differ during TDF treatment (2.6 per 100 PYFU; 95%CI 2.2–3.2) or after its discontinuation (2.2 per 100 PYFU; 95%CI 1.8–2.6). However, the rate of CKD was significantly higher among patients continuing with TDF treatment compared to those who had discontinued it within 6 months of occurrence of mild renal impairment (aIRR 4, 95%CI 2.4–6.8). In contrast, among patients who had maintained TDF >6 months despite mild renal impairment, current TDF use was not associated with a significantly higher rate of CKD. Other significant predictors of CKD were older age, intravenous drug use, diabetes, hypertension, lower pre-TDF eGFR, higher eGFR drop since TDF introduction and longer exposure to TDF.

    Background: Pulmonary infections remain a leading cause of morbidity and mortality and one of the most frequent causes of hospital admission in HIV infected people worldwide. HRCT may be useful in the evaluation of patients with suspected pulmonary disease. The aim of given study was to determine the High Resolution Computed Tomography spectrum of lung parenchymal and interstitial imaging findings in HIV infected patients presented with chest symptoms. Materials and Methods: This study was conducted in a tertiary health care centre, New Delhi, India. The study consisted of 45 patients. A thorough clinical history of all the HIV positive patients presenting with suspicion of pulmonary disease was taken. General physical and respiratory system examination of all patients was done. HRCT scans of the chest were done in all the cases taken in the study. Results: Maximum number of patients was in age group 31-40 years (24 cases). Out of 45 patients included in our study, 32 (71%) were male and 13 (29%) were female. In our series of 45 patients, 62.2% of patients were diagnosed as having pulmonary tuberculosis, followed by bacterial infection in 20% cases and Pneumocystis jiroveci pneumonia (PJP) in 8.9% patients, while 8.9% of the study did not reveal any significant abnormality. Maximum number (22/28) of patients with pulmonary tuberculosis were indentified to have nodular opacities. The most common HRCT finding in bacterial infection was lobar consolidation. The most common HRCT finding in patients with PCP was diffuse ground glass opacities in mosaic pattern of distribution. Conclusion: HRCT is a highly sensitive tool for detecting lung parenchymal and interstitial lesions and allows better characterization of the lesions. HRCT findings should always be correlated with clinical findings, CD4 counts and other available investigations before arriving at a diagnosis or differential diagnosis. PMID:25121043

    Objective To design and pilot test a low vision rehabilitation program for patients with macular disease and cognitive deficits. Methods The Memory or Reasoning Enhanced Low Vision Rehabilitation (MORE-LVR) program was created by a team representing optometry, occupational therapy, ophthalmology, neuropsychology, and geriatrics. Key components of MORE-LVR are: 1) repetitive training with a therapist twice weekly over a 6-week period, 2) simplified training experience addressing no more than three individualized goals in a minimally distracting environment, 3) involvement of an informal companion (friend or family member). Eligible patients were recruited from an LVR clinic; measures were compared before and after the 6 week program. Results Twelve non-demented patients (mean age 84.5 years, 75% female) who screened positive for cognitive deficits completed the MORE-LVR intervention. Participants demonstrated improved scores on the National Eye Institute’s Visual Function Questionnaire (VFQ-25) composite score (47.2±16.3 to 54.8±13.8, p=0.01) and near activities score (21.5±14.0 to 41.0±23.1, p=0.02), timed performance measures (writing a grocery list [p=0.03], filling in a crossword puzzle answer [p=0.003]), a score indicating satisfaction with independence (p=0.05), and logical memory (p=0.02). All patients and companions reported progress toward at least one individualized goal; >70% reported progress toward all three goals. Conclusions This pilot study demonstrates feasibility of an LVR program for macular disease patients with mild cognitive deficits. Participants demonstrated improvements in vision-related function and cognitive measures and expressed high satisfaction. Future work is needed to determine if MORE-LVR is superior to usual outpatient LVR for persons with co-existing visual and cognitive impairments. PMID:23619914

    Multiple sclerosis (MS) is the commonest cause of disability in young adults. While there is increasing choice and better treatments available for delaying disease progression, there are still, very few, effective symptomatic treatments. For many patients such as those with primary progressive MS (PPMS) and those that inevitably become secondary progressive, symptom management is the only treatment available. MS related symptoms are complex, interrelated, and can be interdependent. It requires good understanding of the condition, a holistic multidisciplinary approach, and above all, patient education and empowerment. PMID:26538847

    Purpose COPD is mainly caused by tobacco smoking and is associated with a high frequency of coronary artery disease. There is growing recognition that the inflammation in COPD is not only confined to the lungs but also involves the systemic circulation and can impact nonpulmonary organs, including blood vessels. α1-antitrypsin–low-density lipoprotein (AT-LDL) complex is an oxidatively modified LDL that accelerates atherosclerosis. Curcumin, one of the best-investigated natural products, is a powerful antioxidant. However, the effects of curcumin on AT-LDL remain unknown. We hypothesized that Theracurmin®, a highly absorptive curcumin with improved bioavailability using a drug delivery system, ameliorates the inflammatory status in subjects with mild COPD. Patients and methods This is a randomized, double-blind, parallel-group study. Subjects with stages I–II COPD according to the Japanese Respiratory Society criteria were randomly assigned to receive 90 mg Theracurmin® or placebo twice a day for 24 weeks, and changes in inflammatory parameters were evaluated. Results There were no differences between the Theracurmin® and placebo groups in terms of age, male/female ratio, or body mass index in 39 evaluable subjects. The percent changes in blood pressure and hemoglobin A1c and LDL-cholesterol, triglyceride, or high-density lipoprotein-cholesterol levels after treatment were similar for the two groups. However, the percent change in the AT-LDL level was significantly (P=0.020) lower in the Theracurmin® group compared with the placebo group. Conclusion Theracurmin® reduced levels of atherosclerotic AT-LDL, which may lead to the prevention of future cardiovascular events in mild COPD subjects.

    We evaluated the association between estimated glomerular filtration rate (eGFR) and slow coronary flow (SCF) in patients with normal to mildly impaired renal function; 211 patients with angiographically proven SCF and 219 controls were studied. Patients were categorized based on the angiographic findings as with or without SCF. We used the Modification of Diet in Renal Disease equation to calculate eGFR. The frequency of mildly decreased eGFR, serum uric acid levels, and eGFR was higher in the SCF group. Patients with mildly impaired renal function had higher thrombolysis in myocardial infarction frame counts in 3 major coronary arteries. In logistic regression analysis, uric acid (odds ratio [OR] = 1.323, 95% confidence interval [CI] = 1.109-1.572, P = .002) and eGFR (OR = 0.972, 95% CI = 0.957-0.987, P < .001) were independent correlates of SCF. In conclusion, eGFR was significantly correlated with SCF in patients with normal to mildly impaired renal function.

    Background: Patients with Alzheimer's disease (AD) manifest progressive decline in writing abilities. Most studies on agraphia in AD have been performed in the alphabetic system, such as English. However, these findings may not be applicable to other written language systems. The unique features of the Chinese written script could affect the patterns of agraphia in Chinese AD patients. The aim of this study was to explore the features of writing errors in Chinese patients with AD and amnestic mild cognitive impairment (a-MCI), as well as to study the relationship between their writing errors and neuropsychological functions. Methods: In this study, we performed an observational study in a group of subjects including 17 AD patients, 14 patients with a-MCI, and 16 elderly healthy controls. We analyzed the writing errors in these subjects and also studied the relationship between their writing errors and neuropsychological functions. Results: Our study showed that in patients whose mother tongue is Chinese, writing ability was comparatively well preserved in the MCI phase but significantly impaired when the disease progressed to the stage of AD. The writing errors showed corresponding increase with the severity of cognition decline, both in the types of errors and rate of occurrence. Analysis of the writing errors showed that word substitution and unintelligible words were the most frequent error types that occurred in all the three study groups. The occurrence rate of unintelligible words was significantly higher in the AD group compared with the a-MCI group (P = 0.024) and control group (P = 0.018). In addition, the occurrence rates of word substitution were also significantly higher in AD (P = 0.013) and a-MCI groups (P = 0.037) than that of control group. However, errors such as totally no response, visuospatial impairment, paragraph agraphia, ideograph, and perseverative writing errors were only seen in AD group. Besides, we also found a high occurrence rate of

    We prospectively evaluated erectile function (EF) using the Sexual Health Inventory for Men (SHIM) and the erectile hardness score (EHS) as well as urinary statuses using the International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS) before and 3, 6, and 12 months after a daily treatment with 0.5 mg dutasteride (DUT). Significant improvements were observed in IPSS and OABSS in 98 patients with the DUT treatment, and the effects were similar between 28 patients with potency with baseline SHIM of 8 or greater and 70 severe erectile dysfunction (ED) patients at baseline. In the 28 patients with potency, significant decreases were observed in SHIM and EHS after 3, 6, and 12 months of the DUT treatment, with the severity of ED according to SHIM deteriorating in half of these patients after 12 months of the DUT treatment. Eighteen out of 28 patients (64.3%) with potency at baseline had awareness of the occurrence of ED before the DUT treatment, were younger, and had higher SHIM and EHS just before the DUT treatment than their counterparts. Regular assessments of EF may be needed, especially in younger patients and those with higher levels of EF before the administration of DUT. PMID:26964647

    Abundant data are available for direct anterior/posterior spine fusion (APF) and some for transforaminal lumbar interbody fusion (TLIF), but only few studies from one institution compares the two techniques. One-hundred and thirty-three patients were retrospectively analyzed, 68 having APF and 65 having TLIF. All patients had symptomatic disc degeneration of the lumbar spine. Only those with one or two-level surgeries were included. Clinical chart and radiologic reviews were done, fusion solidity assessed, and functional outcomes determined by pre- and postoperative SF-36 and postoperative Oswestry Disability Index (ODI), and a satisfaction questionnaire. The minimum follow-up was 24 months. The mean operating room time and hospital length of stay were less in the TLIF group. The blood loss was slightly less in the TLIF group (409 vs. 480 cc.). Intra-operative complications were higher in the APF group, mostly due to vein lacerations in the anterior retroperitoneal approach. Postoperative complications were higher in the TLIF group due to graft material extruding against the nerve root or wound drainage. The pseudarthrosis rate was statistically equal (APF 17.6% and TLIF 23.1%) and was higher than most published reports. Significant improvements were noted in both groups for the SF-36 questionnaires. The mean ODI scores at follow-up were 33.5 for the APF and 39.5 for the TLIF group. The patient satisfaction rate was equal for the two groups. PMID:19125304

    While the use of acupuncture as a complementary therapeutic method for treating MCI is popular in certain parts of the world, the underlying mechanism is still elusive. In the current study, we adopted multivariate Granger causality analysis (mGCA) to explore the causal interactions of brain networks involving acupuncture in mild cognitive impairment (MCI) patients compared to healthy controls (HC). The fMRI experiment was performed with two different paradigms: namely, deep acupuncture (DA) and superficial acupuncture (SA) at acupoint KI3. Results demonstrated that deep acupuncture could modulate the abnormal regions in MCI group. These regions are implicated in memory encoding and retrieving. This may relate to the purported therapeutically beneficial effects of acupuncture for the treatment of MCI. However, the most significant causal interactions were found in the sensorimotor regions in HC group. This may because acupuncture has a greater modulatory effect on patients with a pathological imbalance. This paper provides the preliminary neurophysiological evidence for the potential efficacy effect of acupuncture on MCI.

    There has been increasing awareness of the incidence and potential long-term consequences of mild traumatic brain injury (mTBI) in children and young adults. While parents, school systems, and athletic programs are clamoring for evidence-based guidelines, the field remains primitive in understanding the factors resulting in a spectrum of individual outcomes, most of which are complete, but some of which are not. In this article, we discuss the definition, epidemiology, clinical presentation, course, and outcomes of mTBI, with a focus on the pediatric population as the context for reviewing the mechanisms and pathophysiology mediating, and biomarkers reflective of, more significant concussion-induced brain injury. Our goal is to present a general overview of the features of mTBI in the pediatric population in order to provide a conceptual model for pediatricians and pediatric subspecialists. This model emphasizes the importance of establishing actionable, noninvasive biomarkers that are reflective of brain injury and that may identify those pediatric patients who can benefit from earlier and more aggressive interventions. We will focus on the specific features of mTBI in pediatric patients; although given the relative lack of research in the pediatric population, we will also extrapolate from research on adults.

    In our previous studies, we have introduced model-based "unctional biomarkers"or "hysiomarkers"of cerebral hemodynamics that hold promise for improved diagnosis of early-stage Alzheimer’s disease (AD). The advocated methodology utilizes subject-specific data-based dynamic nonlinear models of cerebral hemodynamics to compute indices (serving as possible diagnostic physiomarkers) that quantify the state of cerebral blood flow autoregulation to pressure-changes (CFAP) and cerebral CO2 vasomotor reactivity (CVMR) in each subject. The model is estimated from beat-to-beat measurements of mean arterial blood pressure, mean cerebral blood flow velocity and end18 tidal CO2, which can be made reliably and non-invasively under resting conditions. In a previous study, it was found that a CVMR index quantifying the impairment in CO2 vasomotor reactivity correlates with clinical indications of early AD, offering the prospect of a potentially useful diagnostic tool. In this paper, we explore the use of the same model-based indices for patients with amnestic Mild Cognitive Impairment (MCI), a preclinical stage of AD, relative to a control subjects and clinical cognitive assessments. It was found that the model-based CVMR values were lower for MCI patients relative to the control subjects. PMID:24698010

    We investigated type II deiodinase (DIO2) polymorphisms and serum thyroid hormone levels in subjects with mild cognitive impairment (MCI) in a Uygur population. We studied the DIO2 Thr92Ala (rs225014) and ORFa-Gly3Asp (rs12885300) polymorphisms of 129 unrelated MCI cases and 131 matched controls. All subjects were genotyped using SNaPshot SNP genotyping assays. Serum thyroid hormone levels were measured by radioimmunoassay. Levels of serum triiodothyronine and thyroxine in the MCI group were significantly lower than those in the control group. Genotype and allele frequencies in the DIO2 gene between the MCI and control groups were not significantly different. There was no association in genotype and allele frequencies of Thr92Ala between genders in both groups. ORFa-Gly3Asp genotype and allele frequencies were significantly different in patients and controls by gender. The Asp allele was less frequent among male MCI patients compared to controls (odds ratio = 0.471, 95% confidence interval = 0.261-0.848). However, female Asp carriers were more frequent among MCI patients than among controls (odds ratio = 2.842, 95% confidence interval = 1.326-6.09). Serum levels of triiodothyronine and thyroxine were lower in individuals of the Ala/Ala genotype than in those with the Thr/Thr or Thr/Ala genotype. Serum levels of triiodothyronine were lower in male Gly/Gly carriers than in Gly/Asp or Asp/Asp carriers. Decreased serum levels of triiodothyronine and thyroxine may influence the incidence of MCI in the Uygur population. DIO2 gene polymorphisms may play a role in the incidence of MCI in male patients.

    Introduction Pleural effusion is a common clinical problem that can complicate many medical conditions. Breathlessness is the most common symptom of pleural effusion of any cause and the most common reason for pleural drainage. However, improvement in breathlessness following drainage of an effusion is variable; some patients experience either no benefit or a worsening of their breathlessness. The physiological mechanisms underlying breathlessness in patients with a pleural effusion are unclear and likely to be multifactorial with patient-related and effusion-related factors contributing. A comprehensive study of the physiological and symptom responses to drainage of pleural effusions may provide a clearer understanding of these mechanisms, and may identify predictors of benefit from drainage. The ability to identify those patients whose breathlessness will (or will not) improve after pleural fluid drainage can help avoid unnecessary pleural drainage procedures, their associated morbidities and costs. The PLeural Effusion And Symptom Evaluation (PLEASE) study is a prospective study to comprehensively evaluate factors contributing to pleural effusion-related breathlessness. Methods and analysis The PLEASE study is a single-centre prospective study of 150 patients with symptomatic pleural effusions that require therapeutic drainage. The study aims to identify key factors that underlie breathlessness in patients with pleural effusions and develop predictors of improvement in breathlessness following effusion drainage. Participants will undergo evaluation pre-effusion and post-effusion drainage to assess their level of breathlessness at rest and during exercise, respiratory and other physiological responses as well as respiratory muscle mechanics. Pre-drainage and post-drainage parameters will be collected and compared to identify the key factors and mechanisms that correlate with improvement in breathlessness.

    Muscle dysfunction is a major comorbidity in Chronic Obstructive Pulmonary Disease (COPD). Several biological mechanisms including epigenetic events regulate muscle mass and function in models of muscle atrophy. Investigations conducted so far have focused on the elucidation of biological mechanisms involved in muscle dysfunction in advanced COPD. We assessed whether the epigenetic profile may be altered in the vastus lateralis of patients with mild COPD, normal body composition, and mildly impaired muscle function and exercise capacity. In vastus lateralis (VL) of mild COPD patients with well-preserved body composition and in healthy age-matched controls, expression of DNA methylation, muscle-enriched microRNAs, histone acetyltransferases (HTAs) and deacetylases (HDACs), protein acetylation, small ubiquitin-related modifier (SUMO) ligases, and muscle structure were explored. All subjects were clinically evaluated. Compared to healthy controls, in the VL of mild COPD patients, muscle function and exercise capacity were moderately reduced, DNA methylation levels did not differ, miR-1 expression levels were increased and positively correlated with both forced expiratory volume in one second (FEV1) and quadriceps force, HDAC4 protein levels were increased, and muscle fiber types and sizes were not different. Moderate skeletal muscle dysfunction is a relevant feature in patients with mild COPD and preserved body composition. Several epigenetic events are differentially expressed in the limb muscles of these patients, probably as an attempt to counterbalance the underlying mechanisms that alter muscle function and mass. The study of patients at early stages of their disease is of interest as they are a target for timely therapeutic interventions that may slow down the course of the disease and prevent the deleterious effects of major comorbidities.

    OBJECTIVE--To assess the influence of both sympathetic (plasma noradrenaline concentrations) and parasympathetic (baroreflex activation) tone on survival in patients with congestive heart failure. DESIGN--Invasive study with determination of parasympathetic activity and follow up for at least 4.5 years. SUBJECTS--35 patients with sinus rhythm and mild to moderate heart failure (New York Heart Association grades II-III) (mean age 53 (SD 3)). RESULTS--20 patients whose hearts survived were compared with 15 patients whose hearts did not (12 died and three received transplants). The two groups differed significantly in terms of mean arterial blood pressure (98 (3) v 90 (3) mm Hg), heart rate (82 (2) v 93 (4) beats/min), and mean pulmonary artery pressure (24 (3) v 35 (2) mm Hg) (all P < 0.05), while cardiac index, stroke volume index, and right atrial pressures were not different. The survivors had significantly lower plasma renin activities (3.6 (0.8) v 9.0 (3.6) angiotensin I/ml/h; P < 0.05) and tended to have lower noradrenaline values than non-survivors (170 (23) v 286 (74) pg/ml) at baseline. Baroreflex sensitivity was significantly lower in non- survivors than in survivors (1.3 (0.2) v 2.3 (0.3) ms/mm/Hg); P < 0.02). As the time of cardiac transplantation is dependent on complex logistical factors the three patients who received a transplant were excluded from the analysis of survival time. The risk of death in relation to baroreflex sensitivity at the median sensitivity of 1.48 ms/mm Hg was calculated. Survival was significantly different (P < 0.04) between the resulting two groups; three of the 16 subjects with high baroreflex sensitivity died compared with nine of the 16 with a baroreflex sensitivity < 1.48 ms/mm Hg. When systemic blood pressure, pulmonary artery pressure, stroke volume index, plasma noradrenaline concentrations, and baroreflex sensitivity were entered into a Cox proportional hazards regression, only systolic blood pressure and plasma

    Background: No standard protocols are available for cognitive rehabilitation (CR) in conditions like Major or Mild Neurocognitive disorder (M-NCD or m-NCD, respectively); however, preliminary data seem to indicate that such interventions might have cost-effective beneficial effects and are free from side effect or adverse events. Three basic approaches are known: cognitive stimulation (CS), cognitive training (CT), and CR. Objective: Aim of this study was to assess the efficacy of a protocol of group intensive cognitive activation (g-ICA) in patients with both M-NCD and m-NCD; the protocol was specifically arranged in our Research Institute, based on the principles of the central role of the patient and the mediation pedagogy. Subjects and Methods: Sixteen patients with M-NCD and fifteen patients with m-NCD were enrolled, as well as eleven patients with M-NCD who were used as a control group (CG). The intervention was carried-out by a clinical neuropsychologist with daily group sessions over a period of 2 months. Neuropsychological assessment was performed at baseline and after the completion of the rehabilitative intervention. Results: General cognitive functioning, attention, ideomotor praxis and visual memory scores were found to be significantly increased in all patients. Beneficial and significant effects were also found for constructive praxis in M-NCD and for executive functioning in m-NCD. All areas of the language function were significantly ameliorated in m-NCD, while this happened only for verbal repetition and syntax-grammar comprehension in M-NCD. No changes were detected for long- and short-term verbal memory, which were found to be worsened in controls without activation. Conclusion: Our findings seem to indicate that g-ICA might be effective in inducing beneficial changes on the general cognitive functioning and other specific functions in patients with both m-NCD and M-NCD. Moreover, the specific protocol proposed, even if susceptible of important

    Objectives The aim of this study is to investigate the association between age, gender, body-mass index, smoking behavior, orthopedic comorbidity, neurologic comorbidity, cardiac comorbidity, vascular comorbidity, pulmonic comorbidity, internal comorbidity and Initial Claudication Distance during and after Supervised Exercise Therapy at 1, 3, 6 and 12 months in a large sample of patients with Intermittent Claudication. Methods Data was prospectively collected in standard physiotherapy care. Patients received Supervised Exercise Therapy according to the guideline Intermittent Claudication of the Royal Dutch Society for Physiotherapy. Three-level mixed linear regression analysis was carried out to analyze the association between patient characteristics, comorbidities and Initial Claudication Distance at 1, 3, 6 and 12 months. Results Data from 2995 patients was analyzed. Results showed that being female, advanced age and a high body-mass index were associated with lower Initial Claudication Distance at all-time points (p = 0.000). Besides, a negative association between cardiac comorbidity and Initial Claudication Distance was revealed (p = 0.011). The interaction time by age, time by body-mass index and time by vascular comorbidity were significantly associated with Initial Claudication Distance (p≤ 0.05). Per year increase in age (range: 33–93 years), the reduction in Initial Claudication Distance was 8m after 12 months of Supervised Exercise Therapy. One unit increase in body-mass index (range: 16–44 kg/m2) led to 10m less improvement in Initial Claudication Distance after 12 months and for vascular comorbidity the reduction in improvement was 85m after 12 months. Conclusions This study reveals that females, patients at advanced age, patients with a high body-mass index and cardiac comorbidity are more likely to show less improvement in Initial Claudication Distances (ICD) after 1, 3, 6 and 12 months of Supervised Exercise Therapy.

    A 90-year-old man with a previous history of brain infarction and diabetes mellitus presented with a gait disturbance. Although brain computed tomography (CT) showed no abnormalities, except for the old infarction, the patient experienced recurrent epileptic seizures. He was therefore admitted to our hospital for a further examination of the seizures. However, upon admission, he also presented with a fever and elevated C-reactive protein levels, indicating systemic inflammation. Based on the presence of bilateral infiltration visible on a chest X-radiograph, the patient was diagnosed with aspiration pneumonia. The administration of 4.5 g of sulbactam and ampicillin did not reduce the inflammation or resolve the abnormal lung findings. Therefore, he was intubated and placed on a ventilator. With the patient under ventilator management, we subsequently performed bronchoscopic alveolar lavage. Elevated neutrophil and lymphocyte counts were noted in the alveolar lavage fluid; therefore, we administered pulse steroid therapy with 500 mg of methylprednisolone. The sputum and alveolar lavage fluid samples collected 13 and 14 days, respectively, after admission were negative for Mycobacterium according to a smear test. In contrast, the cultured sputum samples collected on day 13 were positive for Mycobacterium tuberculosis; polymerase chain reaction testing confirmed the sputum culture results. A postmortem pathological examination of the lungs revealed neutrophilic exudative pneumonia as well as acute fibrinous and organizing pneumonia. Although Ziehl-Neelsen staining demonstrated a large number of positive bacteria, no epithelioid-cell granulomas were observed. M. tuberculosis lesions were also found in the liver, spleen, bones, and adrenal glands, suggesting hematogenous dissemination. Aspiration pneumonia is very common in elderly patients with a history of stroke, and these patients are also at risk of other pulmonary disorders and infections including M. tuberculosis

    Mild cognitive impairment (MCI) can occur early in the course of Parkinson's disease (PD), and its presence increases the risk of developing dementia. Determining the cortical changes associated with MCI in PD, thus, may be useful in predicting the future development of dementia. To address this objective, 37 patients with PD, divided into 2 groups according to the presence or absence MCI (18 with and 19 without) and 16 matched controls, underwent anatomic magnetic resonance imaging. Corticometry analyses were performed to measure the changes in cortical thickness and surface area as well as their correlation with disease duration. Compared with healthy controls, the PD-MCI group exhibited increased atrophy and changes of local surface area in the bilateral occipital, left temporal, and frontal cortices; whereas the PD non-MCI group exhibited only unilateral thinning and decreased surface area in the occipital lobe and in the frontal cortex. In addition, a comparison between the PD-MCI and PD non-MCI groups revealed increased local surface area in the occipital lobe, temporal lobe, and postcentral gyrus for the cognitively impaired patients. It is noteworthy that, in the PD-MCI group, cortical thickness had a significant negative correlation with disease duration in the precentral, supramarginal, occipital, and superior temporal cortices; whereas, in the PD non-MCI group, such a correlation was absent. The findings from this study reveal that, at the same stage of PD evolution, the presence of MCI is associated with a higher level of cortical changes, suggesting that cortical degeneration is increased in patients with PD because of the presence of MCI.

    Atherosclerosis is a chronic inflammatory disease with atherosclerotic plaques containing inflammatory cells, including T-lymphocytes, dendritic cells (DCs) and macrophages that are responsible for progression and destabilization of atherosclerotic plaques. Stressed cells undergoing necrosis release molecules that act as endogenous danger signals to alert and activate innate immune cells. In atherosclerotic tissue the number of DCs increases with the progression of the lesion and produce several inflammatory cytokines and growth factors. Triggering receptor expressed on myeloid cells (TREM)-1 plays a crucial role in inflammation. However, relationship of DCs and the role of TREM-1 with the stability of atherosclerotic plaques have not been examined. In this study, we investigated the heterogeneity of the plaque DCs, myeloid (mDC1 and mDC2) and plasmacytoid (pDCs), and examined the expression of TREM-1 and their co-localization with DCs in the plaques from symptomatic (S) and asymptomatic (AS) patients with carotid stenosis. We found increased expression of HLA-DR, fascin, and TREM-1 and decreased expression of TREM-2 and α-smooth muscle actin in S compared to AS atherosclerotic carotid plaques. Both TREM-1 and fascin were co-localized suggesting increased expression of TREM-1 in plaque DCs of S compared to AS patients. These data were supported by increased mRNA transcripts of TREM-1 and decreased mRNA transcripts of TREM-2 in carotid plaques of S compared to AS patients. There was higher density of both CD1c+ mDC1 and CD141+ mDC2 in the carotid plaques from AS compared to S patients, where as the density of CD303+ pDCs were higher in the carotid plaques of S compared to AS patients. These findings suggest a potential role of pDCs and TREM-1 in atherosclerotic plaque vulnerability. Thus, newer therapies could be developed to selectively block TREM-1 for stabilizing atherosclerotic plaques. PMID:27148736

    Background There are numerous studies that address the diagnostic value of dual-source computed tomography (DSCT) as an alternative to conventional coronary angiography (CCA). However, the benefit of application of DSCT in a real world clinical setting should be evaluated. Objectives To determine the diagnostic accuracy of DSCT technique compared with CCA as the gold standard method in detection of coronary artery stenosis among symptomatic patients who are presented to a referral cardiovascular center during daily clinical practice. Patients and Methods Evaluating the medical records of a tertiary care referral cardiovascular center, 47 patients who had undergone DSCT and CCA, and also met the inclusion and exclusion criteria of the study were selected. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and likelihood ratios (LRs) of the DSCT imaging technique were calculated. Results In total, 97.8% of the segments (628/642) could be visualized with diagnostic image quality via DSCT coronary angiography. The mean heart rate during DSCT was 69.2 ± 12.2 bpm (range: 39 - 83 bpm), and the mean Agatston score was 507.7 ± 590.5 (range: 0 - 2328). Per segment analysis of the findings revealed that the sensitivity, specificity, PPV, NPV, positive LR (PLR) and negative LR (NLR) of DSCT technique for evaluation of patients with coronary artery disease were 93.7%, 96.8%, 92.7%, 97.2%, 29.4, and 0.066, respectively. Also per vessel, analysis of the findings showed a sensitivity of 97.1%, a specificity of 94.0%, PPV of 95.3%, NPV of 96.3%, PLR of 16.1, and NLR of 0.030. Conclusion Our results indicate that DSCT coronary angiography provides high diagnostic accuracy for the evaluation of CAD patients during daily routine practice of a referral cardiovascular setting.

  3. Effect of Acetazolamide on Visual Function in Patients With Idiopathic Intracranial Hypertension and Mild Visual Loss

    2015-01-01

    IMPORTANCE Acetazolamide is commonly used to treat idiopathic intracranial hypertension (IIH), but there is insufficient information to establish an evidence base for its use. OBJECTIVE To determine whether acetazolamide is beneficial in improving vision when added to a low-sodium weight reduction diet in patients with IIH and mild visual loss. DESIGN, SETTING, AND PARTICIPANTS Multicenter, randomized, double-masked, placebo-controlled study of acetazolamide in 165 participants with IIH and mild visual loss who received a low-sodium weight-reduction diet. Participants were enrolled at 38 academic and private practice sites in North America from March 2010 to November 2012 and followed up for 6 months (last visit in June 2013). All participants met the modified Dandy criteria for IIH and had a perimetric mean deviation (PMD) between −2 dB and −7 dB. The mean age was 29 years and all but 4 participants were women. INTERVENTIONS Low-sodium weight-reduction diet plus the maximally tolerated dosage or acetazolamide (up to 4 g/d) or matching placebo for 6 months. MAIN OUTCOMES AND MEASURES The planned primary outcome variable was the change in PMD from baseline to month 6 in the most affected eye, as measured by Humphrey Field Analyzer. Perimetric mean deviation is a measure of global visual field loss (mean deviation from age-corrected normal values), with a range of 2 to −32 dB; larger negative values indicate greater vision loss. Secondary outcome variables included changes in papilledema grade, quality of life (Visual Function Questionnaire 25 [VFQ-25] and 36-Item Short Form Health Survey), headache disability, and weight at month 6. RESULTS The mean improvement in PMD was greater with acetazolamide (1.43 dB, from −3.53 dB at baseline to −2.10 dB at month 6; n = 86) than with placebo (0.71 dB, from −3.53 dB to −2.82 dB;n = 79); the difference was 0.71 dB (95% CI, 0 to 1.43 dB; P= .050). Mean improvements in papilledema grade (acetazolamide: −1

    The presence of CD19 in myelomatous plasma cells (MM-PCs) correlates with adverse prognosis in multiple myeloma (MM). Although CD19 expression is upregulated by CD81, this marker has been poorly investigated and its prognostic value in MM remains unknown. We have analyzed CD81 expression by multiparameter flow cytometry in MM-PCs from 230 MM patients at diagnosis included in the Grupo Español de Mieloma (GEM)05>65 years trial as well as 56 high-risk smoldering MM (SMM). CD81 expression was detected in 45% (103/230) MM patients, and the detection of CD81(+) MM-PC was an independent prognostic factor for progression-free (hazard ratio=1.9; P=0.003) and overall survival (hazard ratio=2.0; P=0.02); this adverse impact was validated in an additional series of 325 transplant-candidate MM patients included in the GEM05 <65 years trial. Moreover, CD81(+) SMM (n=34/56, 57%) patients had a shorter time to progression to MM (P=0.02). Overall, our results show that CD81 may have a relevant role in MM pathogenesis and represent a novel adverse prognostic marker in myeloma. PMID:22333880

    Purpose To investigate the safety and outcome of intracranial stenting for intracranial atherosclerotic stenosis (IAS). Materials and Methods Between July 2007 and April 2013, 433 consecutive patients with IAS >70% underwent intracranial Wingspan stenting, and the data were prospectively analyzed. Results Intracranial stenting was successful in 429 patients (99.1%), and the mean stenosis rate was improved from prestenting (82.3± 7.6)% to poststenting (16.6 ± 6.6)%. During the 30-day perioperative period, 29 patients (6.7%) developed stroke. The total perioperative stroke rate was significantly (P <0.01) higher in the basilar artery area than in others, whereas the hemorrhagic stroke rate was significantly (P <0.05) greater in the middle cerebral artery area than in others. The experience accumulation stage (13%) had a significantly (P <0.05) higher stroke rate than the technical maturation stage (4.8%). Clinical follow-up 6–69 months poststenting revealed ipsilateral stroke in 20 patients (5.5%). The one- and two-year cumulative stroke rates were 9.5% and 11.5%, respectively; the two-year cumulative stroke rate was significantly (P <0.05) greater in the experience accumulation stage (18.8%) than in the technical maturation stage (9.1%). Conclusion Wingspan stenting for intracranial atherosclerotic stenosis is safe and the long-term stroke rate after stenting is low in a Chinese subpopulation. PMID:26422692

    Background This study assessed the long-term safety and efficacy of tiotropium Respimat, a long-acting inhaled anticholinergic bronchodilator, in asthma, added on to inhaled corticosteroids (ICS) with or without long-acting β2-agonist (LABA). Methods 285 patients with symptomatic asthma, despite treatment with ICS±LABA, were randomised 2:2:1 to once-daily tiotropium 5 μg, tiotropium 2.5 μg or placebo for 52 weeks (via the Respimat SoftMist inhaler) added on to ICS±LABA, in a double-blind, placebo-controlled, parallel-group study (NCT01340209). Primary objective: to describe the long-term safety profile of tiotropium. Secondary end points included: trough forced expiratory volume in 1 second (FEV1) response; peak expiratory flow rate (PEFR) response; seven-question Asthma Control Questionnaire (ACQ-7) score. Results At Week 52, adverse-event (AE) rates with tiotropium 5 μg, 2.5 μg and placebo were 88.6%, 86.8% and 89.5%, respectively. Commonly reported AEs with tiotropium 5 μg, 2.5 μg and placebo were nasopharyngitis (48.2%, 44.7%, 42.1%), asthma (28.9%, 29.8%, 38.6%), decreased PEFR (15.8%, 7.9%, 21.1%), bronchitis (9.6%, 13.2%, 7.0%), pharyngitis (7.9%, 13.2%, 3.5%) and gastroenteritis (10.5%, 3.5%, 5.3%). In the tiotropium 5 μg, 2.5 μg and placebo groups, 8.8%, 5.3% and 5.3% of patients reported drug-related AEs; 3.5%, 3.5% and 15.8% reported serious AEs. Asthma worsening was the only serious AE reported in more than one patient. At Week 52, adjusted mean trough FEV1 and trough PEFR responses were significantly higher with tiotropium 5 μg (but not 2.5 μg) versus placebo. ACQ-7 responder rates were higher with tiotropium 5 μg and 2.5 μg versus placebo at Week 24. Conclusions The long-term tiotropium Respimat safety profile was comparable with that of placebo Respimat, and associated with mild to moderate, non-serious AEs in patients with symptomatic asthma despite ICS±LABA therapy. Compared with placebo, tiotropium 5 μg, but not 2.5

    AIM: To clarify the pathogenesis of gastroesophageal reflux disease symptoms in non-erosive reflux disease (NERD) patients. METHODS: Thirty-five NERD patients with persistent symptoms, despite taking rabeprazole 10 mg twice daily for at least 8 wk, were included in this study. All patients underwent 24 h combined impedance - pH on rabeprazole. The symptom index (SI) was considered to be positive if ≥ 50%, and proximal reflux episodes were determined when reflux reached 15 cm above the proximal margin of the lower esophageal sphincter. RESULTS: In 14 (40%) SI-positive patients, with liquid weakly acid reflux, the occurrence rate of reflux symptoms was significantly more frequent in proximal reflux episodes (46.7%) than in distal ones (5.7%) (P < 0.001). With liquid acid reflux, there were no significant differences in the occurrence rate of reflux symptoms between proximal reflux episodes (38.5%) and distal ones (20.5%) (NS). With mixed liquid-gas weakly acid reflux, the occurrence rate of reflux symptoms in proximal reflux episodes was significantly more frequent (31.0%) than in distal reflux ones (3.3%) (P < 0.001). With mixed liquid-gas acid reflux, there were no significant differences in the occurrence rate of reflux symptoms between proximal reflux episodes (29.4%) and distal ones (14.3%) (NS). CONCLUSION: The proximal extent of weakly acidic liquid and mixed liquid-gas reflux is a major factor associated with reflux perception in SI-positive patients on proton pump inhibitor therapy.

    Swallowing mechanism and neurogenic dysphagia in MS have been rarely studied by electromyographical (EMG) methods. This study aims to evaluate the presence of subclinical dysphagia in patients with mild multiple sclerosis (MS) using electrophysiological methods. A prospective study of 51 patients with relapsing remitting multiple sclerosis and 18 age-matched healthy adults was investigated. We used electromyography to measure the activity of the submental muscles during swallowing. Electrophysiological recordings of patients were obtained during relapse, after relapse, and at any time in remission period. Clinical dysphagia was found in 12% of MS patients, while electrophysiological swallowing abnormalities were encountered in 33% of patients. Subclinical dysphagia was determined in 35% of patients during an MS relapse, in 20% of patients after a relapse, and in 25% of all 51 patients in the remission period based on EMG findings. Duration of swallowing signal of submental muscles in all MS patients was found to be longer than in normal subjects (p = 0.001). During swallowing of 50 ml of sequential water, the compensatory respiratory cycles occurred more often in MS patients than normal subjects, especially during a relapse (p = 0.005). This is the first study investigating swallowing abnormalities and subclinical dysphagia from the electrophysiological aspect in MS patients with mild disability. The electrophysiological tests described in this study are useful to uncover subclinical dysphagia since they have the advantage of being rapid, easy to apply, non-invasive, and without risk for the patients.

    Patients with rosacea form a unique subset of the sensitive skin population because of the barrier defects inherent in this condition and the increased propensity for burning/stinging from topical products. This propensity for burning/ stinging when medications, skin care products, or cosmetics are applied to the facial skin has been frequently documented but never quantified. The objective of this 2-week study was to determine the prevalence of heightened neurosensory perceptions of burning/stinging in a random population of 40 women with mild to moderate rosacea defined as 15 or fewer inflammatory papules or pustules. Also evaluated was the effect of azelaic acid 15% gel on barrier function and facial stinging utilizing transepidermal water loss (TEWL), corneometry, and lactic acid facial sting tests as noninvasive measurement criteria. At baseline, the incidence of lactic acid stinging among these rosacea subjects was 62.5%, which is substantially higher than observed in the general population. Two weeks after application of azelaic acid 15% gel, no evidence of barrier damage was noted on TEWL or corneometry tests. Moreover, there was no statistical relationship between lactic acid stinging and a stinging response that is occasionally reported with exposure to azelaic acid 15% gel. PMID:15551720

    Abstract The periaqueductal gray (PAG) plays a pivotal role in pain modulation. We attempted to examine the relation between injury of the PAG and central pain in patients with mild traumatic brain injury (TBI). Sixty-one patients with mild TBI with central pain and 31 healthy control subjects were recruited for this study. Visual analog scale (VAS) was used for evaluation of central pain. The region of interest was defined for the PAG and the fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were measured. The FA value was significantly lower in the patient group than in the control group (P < 0.05). However, no significant difference in the ADC value was observed between the patient and control groups (P > 0.05). VAS score of the patient group showed significant moderate negative correlation with the FA (r = −0.38), while no significant correlation was observed between VAS score and the ADC value (P < 0.05). We demonstrated injury of the PAG in patients with central pain following mild TBI and the degree of injury of the PAG was closely related to the degree of central pain. PMID:27368020

    Memory for object locations, as part of spatial memory function, has rarely been studied in patients with Alzheimer dementia (AD), while studies in patients with Mild Cognitive Impairment (MCI) patients are lacking altogether. The present study examined categorical spatial memory function using the Location Learning Test (LLT) in MCI patients (n = 30), AD patients (n = 30), and healthy controls (n = 40). Two scoring methods were compared, aimed at disentangling positional recall (location irrespective of object identity) and object-location binding. The results showed that AD patients performed worse than the MCI patients on the LLT, both on recall of positional information and on recall of the locations of different objects. In addition, both measures could validly discriminate between AD and MCI patients. These findings are in agreement with the notion that visual cued-recall tests may have better diagnostic value than traditional (verbal) free-recall tests in the assessment of patients with suspected MCI or AD.

    Background: Although mental fatigue was well-recognized as one of the long-term consequences following mild traumatic brain injury (MTBI) that required ongoing support, evidences for the optimal management remained inadequate. Aims: To investigate the temporal profile of mental fatigue during the first year after MTBI and examine the impact of perceived social support on the recovery from post-MTBI fatigue. Study Design: Observational case-control study. Methods: This study was conducted among post-MTBI patients admitted to the emergency department in a tertiary-care hospital in Sichuan, China. During four waves of assessments at 1 week, 3, 6 and 12 months, mental fatigue was assessed through Mental Fatigue Scale (MFS) whereas social support was assessed by the Multidimensional Scale of Perceived Social Support (MSPSS). Results: There were 65.1%, 37.1%, 34.8% and 32.5% individuals being identified as those with mental fatigue at 1 week, 3, 6 and 12 months, respectively. The scores of MFS didn’t change substantially since 3 months post-injury. Compared to non-fatigued MTBI patients, those with long-lasting post- MTBI fatigue reported extremely lower level of perceived social support. Moreover, improved social support at 1 week was negatively associated with the occurrence of long-lasting fatigue. Conclusion: Sufficient social support could significantly decrease the occurrence of long-lasting mental fatigue among MTBI cases. It seemed of great importance to modify the emphasis of rehabilitation to include assessment and improvement of perceived social support at earlier stages after injury. PMID:27403383

    Mild cognitive impairment (MCI) is considered as the early stage of dementia which currently has no effective treatments. Reducing progression of cognitive decline at the MCI stage could be an important strategy for preventing conversion to dementia. The goal of this work was to screen for clinical predictors indicating the prognosis of MCI comprehensively; therefore, we assumed vascular risk factors (VRFs), carotid stenosis, and white matter changes (WMC) to be independent predictors. A total of 257 patients with MCI underwent collection of VRF information, neuropsychological evaluation, computed tomography angiography (CTA) to investigate carotid stenosis, and magnetic resonance imaging (MRI) to identify severity of WMC. After a 3-year follow-up period, the neuropsychological evaluation, CTA, and MRI were repeated to assess the progression of cognitive decline, carotid stenosis, and WMC. The conversion rate from MCI to dementia was 11.65% per year, and the conversion rate from MCI to Alzheimer's disease was 7.05% per year in our cohort. Cognitive decline (in terms of changes in Mini Mental State Examination scores) was associated with diabetes mellitus (p = 0.004), baseline WMC severity (p < 0.001), baseline carotid stenosis (p < 0.001), and WMC severity change (p < 0.001). Besides, diabetes, baseline WMC severity, baseline moderate-to-severe carotid stenosis, and carotid stenosis change during follow-up were predictors of conversion from MCI to dementia. Given the potential clinical predictors, our findings could imply that controlling blood glucose, removing carotid stenosis, and improving cerebral perfusion could be effective measures to delay cognitive decline in patients with MCI and prevent conversion from MCI to dementia.

    Situs inversus with dextrocardia is a congenital condition in which the heart is a mirror image of the anatomically normal heart on the right side. A patient presented with the sick sinus syndrome accompanying mirror image dextrocardia which was associated with double superior vena cava and a left sided inferior vena cava A permanent transvenous demand pacemaker was inserted because of repeated episodes of dizziness and a single episode of syncope with ECG showing bradycardia with junctional escape rhythm. Precise knowledge of the venous system and the location of the apex of the right ventricle were necessary prior to permanent pacemaker implantation. Without such knowledge pacing may be technically challenging.

    Summary Percutaneous transluminal angioplasty (PTA) has recently become a noteworthy treatment option for significant stenosis involving the vertebral artery (VA) in selected patients. We conducted a prospective study to evaluate the efficacy, safety and mid-term follow up results of 206 cases received PTA with or without stent implant to treat their symptomatic atherosclerotic VA stenosis in all segments (V1-V4). In a prospective mono-arm trial from October 2008 to July 2012 in a single center, 239 lesions affecting the intra or extracranial VA (171 in V1, 17 in V2, 14 in V3, 21 in V4 and 16 in combined segments) were treated by PTA with or without stent implant. Non-disabling stroke patients who had failed conservative medical treatment and had angiographic evidence of >50% stenosis in the dominant VA with clinical signs and symptoms of VB stenosis were included in this study. They were mean followed for 13.15±5.24 months after treatment. Overall, 206 patients underwent the procedure. A stent was implemented in 199 patients (96.6%). The periprocedural complication rate was 7.2%. The procedural (technical) success rate was 97.6%. Of the total 239 lesions, 223 were treated with stent implant. Clinical success was achieved in all 206 symptomatic patients after the procedure. Restenosis occurred in 15.9% after a mean 10.8 (6-24) months. Of those, 63.1% and 34.2% had mild and moderate stenosis that was treated medically, whereas one case (2.6%) with severe restenosis underwent balloon angioplasty. No deaths occurred during the follow-up period. The follow-up complication rate was 6.3%. TIA occurred in 4.4%, a minor stroke in 1.4% and a major stroke in one patient. The overall patient event-free survival was 92.4%. These results demonstrate the safety and feasibility of PTA with or without stent implant, with a high technical success rate, a low complication rate, a low restenosis rate and durable clinical success in patients with symptomatic VA stenosis.

    The pathophysiology of preterm delivery (PTD) is complex and multifactorial.It occurs in 8-12% of all deliveries, and the rate of PTD has increased during the past years in spite of intensive efforts towards early detection and prompt treatment. Fifty-eight pregnant women were eligible to join the study if they attended the University Clinic for Gynecology and Obstetrics, Skopje and were admitted to Department of High Risk pregnancy Unit with symptoms of preterm labor (PTL) (symptoms of uterine activity judged by the assessing physician to be indicative of PTL) at 24.0 to 36.6 weeks gestation.Test specimens for fetal fibronectin (fFN), phosphorylated insulin like growth factor binding protein 1 (phIGFBP-1), IL-6, and IL-2R and measuring the cervical length via transvaginal ultrasound were performed for each patient. The best statistical model for predicting PTL in the present study was to use a combination of the phIGFBP-1 test, a positive fFN test, cervical length less than 21.5 mm, levels of IL-6 higher than 1,305 pg/ml in the cervico-vaginal fluid (CVF), and serum levels of C-reactive protein (CRP) higher than 6.1 mg/L which was excellent at identifying the patients that were to deliver within 14 days of admittance.

    Introduction Increased human immunodeficiency virus (HIV) virulence at infection has been suggested by a meta-analysis based on viral load and CD4 T lymphocytes (CD4) count during acute infection. This result was obtained after secondary analyses of large databases, facilitating the detection of differences. Similar finding in cohorts of more modest sample size would indicate that the effect could be more substantial. Methods Change from initial CD4 count and HIV viral load after acute HIV infection by calendar year was explored in patients treated at Lyon University hospitals. All patients admitted to our hospitals with acute HIV infection between 1996 and 2013 were included in our study. Initial CD4 count and viral load before the start of anti-retroviral treatment were analyzed. Trends over time were assessed in linear models. Results Initial CD4 count remained similar over time. However, in 2006–2013, initial viral load rose significantly (+1.12 log10/ml/year, p = 0.01). Conclusion Our data, obtained from a single hospital cohort, confirmed findings from a large meta-analysis, showed increased initial viremia at acute HIV infection since 2006 and suggesting potentially higher HIV virulence in recent years.

    The purpose of this study was to describe our technique and results of arthroscopic resection of a symptomatic os trigonum via two posterior portals in 10 cases. Between 1999 and 2005 we treated 10 patients with endoscopic resection of a symptomatic os trigonum. The age ranged between 19 and 32 years (average 25.9). The average follow-up was 25 months (6-61 months). Time interval between the onset of pain and endoscopic resection of the os trigonum was 20 months. Of the 10 patients, 9 were symptom free for activities of daily living (ADL) within 4 weeks after surgery. They resumed their professional sport activities in a period of 8 weeks. The average AOFAS ankle/hindfoot scale increased from 43 preoperative to 87 postoperatively. We observed no complication in these 10 patients. Endoscopic resection of the symptomatic os trigonum yields good results with minimal surgical morbidity and short recovery time.

    OBJECTIVE To test the hypothesis that since mild cognitive impairment (MCI), believed to be an intermediary state on the way to, and Alzheimer’s disease (AD) are both neurodegenerative, quantification of the neuronal marker, N-acetylaspartate (NAA) in their whole brain (WBNAA) could differentiate them from cognitively intact matched controls. METHODS Proton MR spectroscopy to quantify the WBNAA was applied to 197 subjects (86 females) 72.6±8.4 years old (mean±standard deviation). Of these, 102 were cognitively intact, 42 diagnosed as MCI and 53 as probable AD. Their WBNAA amounts were converted into absolute concentration by dividing with the brain volume segmented from the MRI that also yielded the fractional brain volume (fBPV), an atrophy metric. RESULTS WBNAA concentration of MCI and AD patients (10.5±3.0 and 10.1±2.9mM) were not significantly different (p=0.85), they were, however, highly significantly 25–29% lower than the 14.1±2.4mM of normal matched controls (p‹10−4). The fBPV of MCI and AD patients (72.9±4.9 and 69.9±4.7%) differed significantly from each other (4%, p=0.02) and both were significantly lower than the 74.6±4.4% of normal elderly (2%, p=0.003 for MCI; 6%, p‹10−4 for AD). ROC curve analysis has shown WBNAA to have 70.5% sensitivity and 84.3% specificity to differentiate MCI or AD patients from normal elderly versus just 68.4 and 65.7% for fBPV. CONCLUSION Low WBNAA in MCI patients compared with cognitively normal contemporaries may indicate early neuronal damage accumulation and supports the notion of MCI as an early stage of AD. It also suggests WBNAA as a potential marker of early AD pathology. PMID:25125458

    Background Stroke is the fourth leading cause of death in the United States, leading to devastating disability. Most strokes are ischemic, and nearly one-third of these are caused by carotid disease. The primary mechanism of carotid-related stroke is an atheroembolic event from an unstable atherosclerotic plaque rupture. In the 1990s, randomized trials demonstrated the benefit of carotid endarterectomy (CEA) in reducing the risk of stroke in both symptomatic and asymptomatic carotid disease. Methods We review best medical therapy (BMT) for asymptomatic carotid disease and recent randomized trials comparing CEA and carotid angioplasty stenting (CAS), and we discuss the role of urgent carotid interventions in patients with acute neurologic symptoms. Results In 2010, 2 large trials demonstrated the efficacy of CAS in select patients, although CAS was associated with an increased procedural stroke risk compared to CEA. An age effect was observed; patients >75 years do worse with CAS compared to CEA. As BMT has evolved in the past decade, a future trial (CREST-2) will address whether BMT is equal to intervention (CEA or CAS) in asymptomatic carotid disease. In a subgroup of patients with asymptomatic carotid disease, CEA plus BMT will likely remain the mainstay therapy for carotid disease compared to BMT alone. CEA and CAS will continue to play complementary roles in the future, as CAS will be done in select patients in whom CEA cannot be undertaken because of high-risk anatomical or medical conditions. Finally, a role for urgent carotid interventions in a select group of patients who present with acute neurologic symptoms is developing as a way to prevent recurrent stroke after an initial carotid plaque rupture event. Conclusion CAS has an increasingly higher risk of stroke with advancing age. Patients treated with CAS have a 1.76-fold increased risk of stroke (95% CI, 1.35-2.31) with each 10-year increase in age. No such age effect is seen in patients treated with CEA

    Summary Background Stents are an alternative treatment to carotid endarterectomy for symptomatic carotid stenosis, but previous trials have not established equivalent safety and efficacy. We compared the safety of carotid artery stenting with that of carotid endarterectomy. Methods The International Carotid Stenting Study (ICSS) is a multicentre, international, randomised controlled trial with blinded adjudication of outcomes. Patients with recently symptomatic carotid artery stenosis were randomly assigned in a 1:1 ratio to receive carotid artery stenting or carotid endarterectomy. Randomisation was by telephone call or fax to a central computerised service and was stratified by centre with minimisation for sex, age, contralateral occlusion, and side of the randomised artery. Patients and investigators were not masked to treatment assignment. Patients were followed up by independent clinicians not directly involved in delivering the randomised treatment. The primary outcome measure of the trial is the 3-year rate of fatal or disabling stroke in any territory, which has not been analysed yet. The main outcome measure for the interim safety analysis was the 120-day rate of stroke, death, or procedural myocardial infarction. Analysis was by intention to treat (ITT). This study is registered, number ISRCTN25337470. Findings The trial enrolled 1713 patients (stenting group, n=855; endarterectomy group, n=858). Two patients in the stenting group and one in the endarterectomy group withdrew immediately after randomisation, and were not included in the ITT analysis. Between randomisation and 120 days, there were 34 (Kaplan-Meier estimate 4·0%) events of disabling stroke or death in the stenting group compared with 27 (3·2%) events in the endarterectomy group (hazard ratio [HR] 1·28, 95% CI 0·77–2·11). The incidence of stroke, death, or procedural myocardial infarction was 8·5% in the stenting group compared with 5·2% in the endarterectomy group (72 vs 44 events

    Purpose: Preclinical studies have suggested that angiotensin-converting enzyme inhibitors (ACEIs) can mitigate radiation-induced lung injury. We sought here to investigate possible associations between ACEI use and the risk of symptomatic radiation pneumonitis (RP) among patients undergoing radiation therapy (RT) for non–small cell lung cancer (NSCLC). Methods and Materials: We retrospectively identified patients who received definitive radiation therapy for stages I to III NSCLC between 2004 and 2010 at a single tertiary cancer center. Patients must have received a radiation dose of at least 60 Gy for a single primary lung tumor and have had imaging and dosimetric data available for analysis. RP was quantified according to Common Terminology Criteria for Adverse Events, version 3.0. A Cox proportional hazard model was used to assess potential associations between ACEI use and risk of symptomatic RP. Results: Of 413 patients analyzed, 65 were using ACEIs during RT. In univariate analysis, the rate of RP grade ≥2 seemed lower in ACEI users than in nonusers (34% vs 46%), but this apparent difference was not statistically significant (P=.06). In multivariate analysis of all patients, ACEI use was not associated with the risk of symptomatic RP (hazard ratio [HR] = 0.66; P=.07) after adjustment for sex, smoking status, mean lung dose (MLD), and concurrent carboplatin and paclitaxel chemotherapy. Subgroup analysis showed that ACEI use did have a protective effect from RP grade ≥2 among patients who received a low (≤20-Gy) MLD (P<.01) or were male (P=.04). Conclusions: A trend toward reduction in symptomatic RP among patients taking ACEIs during RT for NSCLC was not statistically significant on univariate or multivariate analyses, although certain subgroups may benefit from use (ie, male patients and those receiving low MLD). The evidence at this point is insufficient to establish whether the use of ACEIs does or does not reduce the risk of RP.

    10% of symptomatic parotid stones cannot be removed by minimally invasive radiological or endoscopic techniques alone. In these cases endoscopically assisted surgical parotid sialolithectomy can be performed via an extraoral approach, reconstituting the duct and preserving functioning glandular tissue. Between 2003 and 2010, 55 consecutive patients underwent endoscopically assisted surgical removal of parotid stones from 57 glands, two having bilateral procedures. Outcome was assessed using a structured questionnaire. 39/55 patients (71%) patients were successfully contacted (40 procedures; one bilateral case). At median follow-up of 3.1 years 28 glands (70%) were symptomless, whilst 11 (28%) were much improved but causing mild or occasional residual symptoms. One patient required postoperative lithotripsy and basket retrieval of a retained stone, but was subsequently symptom free. A further patient was initially symptom free then relapsed, did not respond to lithotripsy and is awaiting further assessment. In 10% of cases a short-lived sialocoele developed postoperatively. No individual reported facial weakness and one had a scar of concern. 37/39 (95%) patients were pleased to have had the operation and would have the procedure contralaterally in similar circumstances. Endoscopically assisted surgical removal of parotid stones is a successful technique with low morbidity that is well received by patients. PMID:22018956

    It is estimated that in Europe 10% of adults suffer from chronic sinusitis. Chronic sinusitis can be caused by many different diseases that share chronic inflammation of the sinuses as a common symptom. Rhinitis can be caused by stomach acid coming up from the stomach into the esophagus, which successively can result in chronic sinusitis. The current gold standard for diagnosing GERD is--bothersome for the patient--24 h esophageal pH monitoring. This method can be unpleasant for the patients, which makes it less acceptable. Because of that the criteria for symptomatic GERD were made an alternative diagnostic way. We acknowledge that the presence of heartburn and stomach acid coming up from the stomach into the esophagus at least once a week can be diagnosed as symptomatic GERD. The aim of the study is the assessment of the frequency of symptomatic GERD in patients operated because of chronic sinusitis and impact of symptomatic GERD on the follow-up treatment up to 12 months after endoscopic nasal surgery. The authors analysed 144 patients operated at the JUCM Otolaryngological Clinic in Kraków between 2011 and 2013 because of sinusitis. The inclusion criteria were: diagnosed chronic sinusitis, indications for endoscopic sinus surgery, and a written consent for the research. Each patient was examined laryngologically and surveyed. Patients were divided into two groups: with and without symptomatic GERD. We analysed the symptoms in patients treated for sinusitis with or without GERD before, between 3 and 6 as well as in the 12th month after endonasal surgery. Moreover, we analysed the intensity of the global symptoms (expressed in the VAS scale) and separately for each of the 13 symptoms of chronic sinusitis (expressed on a scale 0 - 3). We established that 33 out of the 144 patients (22.9%) qualified for the first survey reported the symptoms of GERD. In the second survey, which was conducted between 3 and 6 month after ESS, 24 out of 119 (20%) people reported the

    OBJECTIVES: Naming deficit is a linguistic symptom that appears in the initial phase of Alzheimer's disease, but the types of naming errors and the ways in which this deficit changes over the course of the disease are unclear. We analyzed the performance of patients with Alzheimer's disease on naming tasks during the mild and moderate phases and verified how this linguistic skill deteriorates over the course of the disease. METHODS: A reduced version of the Boston Naming Test was administered to 30 patients with mild Alzheimer's disease, 30 patients with moderate Alzheimer's disease and 30 healthy controls. Errors were classified as verbal semantic paraphasia, verbal phonemic paraphasia, no response (pure anomia), circumlocution, unrelated verbal paraphasia, visual errors or intrusion errors. RESULTS: The patients with moderate Alzheimer's disease had significantly fewer correct answers than did both the control group and the group with mild Alzheimer's disease. With regard to the pattern of errors, verbal semantic paraphasia errors were the most frequent errors in all three groups. Additionally, as the disease severity increased, there was an increase in the number of no-response errors (pure anomia). The group with moderate Alzheimer's disease demonstrated a greater incidence of visual errors and unrelated verbal paraphasias compared with the other two groups and presented a more variable pattern of errors. CONCLUSIONS: Performance on nominative tasks worsened as the disease progressed in terms of both the quantity and the type of errors encountered. This result reflects impairment at different levels of linguistic processing. PMID:26106961

    Objectives To compare expression of interleukin (IL)-1β and tumour necrosis factor (TNF)-α in the conjunctiva of diabetic and non-diabetic patients with symptomatic moderate dry eye. Setting and participants Nineteen diabetic patients with dry eye, 15 non-diabetic patients with dry eye and 14 diabetic patients without dry eye were recruited. The relative expression of IL-1β and TNF-α in conjunctival impression cytology (CIC) specimens was evaluated using immunofluorescent staining and in conjunctival biopsy specimens using immunohistochemical staining. Results The diabetic dry eye group showed significantly higher grades of metaplasia than the non-diabetic dry eye and diabetic without dry eye groups (both p<0.05). There was no significant difference in the concentration of IL-1β and TNF-α in CIC specimens between the three groups (p=0.504 and p=0.310, respectively). The mean levels of IL-1β and TNF-α in conjunctival biopsy specimens from the diabetic dry eye group was significantly increased compared with the non-diabetic dry eye and diabetic without dry eye groups (p=0.002, p<0.001; p=0.001, p<0.001, respectively). Interestingly, IL-1β- and TNF-α-positive cells were mainly located in the basal layer of the conjunctival epithelium, and rarely seen in the apical conjunctival epithelium in the three groups. The levels of both IL-1β and TNF-α did not correlate with conjunctival squamous metaplasia grades. Conclusions Levels of IL-1β and TNF-α in conjunctival biopsy specimens were increased in diabetic patients with dry eye, while levels of IL-1β and TNF-α in apical conjunctival epithelium were similar in the CIC specimens. These findings suggest that the inflammatory response is not limited to the surface of conjunctival epithelial cells, and is more serious in the basal layer of the epithelium, which may play an important role in the pathogenesis of dry eye in diabetic patients.

  9. High prevalence of pfcrt-CVIET haplotype in isolates from asymptomatic and symptomatic patients in south-central Oromia, Ethiopia

    PubMed Central

    2014-01-01

    Background As a result of extensive chloroquine resistance (CQR) in Plasmodium falciparum in late 1990s, Ethiopia replaced CQ with sulphadoxine-pyrimethamine (SP) as first-line drug, which in turn was replaced by artemisinin combination therapy in 2004. Plasmodium falciparum resistance to CQ is determined by the mutation at K76T of the P. falciparum chloroquine resistance transporter (pfcrt) gene. Understanding diversity in the P. falciparum genome is crucial since it has the potential to influence important phenotypes of the parasite such as drug resistance. Limited data is available regarding the type of pfcrt mutant allelic type, the effect of CQ withdrawal and diversity of the parasite population in south-central Oromia, Ethiopia. Methods Finger-pricked blood spotted on Whatman 3MM filter papers were collected from falciparum malaria patients. Parasite DNA was extracted from individual blood spots on the filter papers. The presence of K76T mutations was determined using nested PCR for all isolates. Complete sequencing of mutations in pfcrt 72-76 was done for a set of randomly selected resistant isolates. Four microsatellite (MS) markers were analysed to determine the heterozygosity. Results Although CQ was withdrawn for more than a decade, 100% of the parasites still carried the pfcrt K76T mutation. All isolates were mutant at the K76T polymorphism. Based on combinations of MS markers, seven different Ethiopian CQR variants (E1-E7) were identified. Heterozygosity (He) for MS flanking the pfcrt chloroquine resistance allele ranged from 0.00 (mscrt -29, -29.268 kb) to 0.21 (mscrt -2, -2.814 kb). He ranged from 0.00 (msint 3, 0 kb) to 0.19 (msint 2, 0 kb) for MS within the pfcrt gene. Both intronic and MS flanking the pfcrt gene showed low levels of diversity. Conclusion pfcrt CQR allele seems to be fixed in the study area. Of the different haplotypes associated with CQR, only the CVIET genotype was identified. No reversal to the wild-type has occurred in

    The Q-T interval and apex of T wave to end of T wave (aT-eT) interval were measured by computer in four age-matched study groups at rest and during exercise to determine whether: the behavior of the aT-eT interval differs in patients with myocardial ischemia when compared with normal subjects, and the behavior of the aT-eT interval differs in subjects with true positive and false positive ST segment responses. Group I consisted of 57 normal subjects. Group II consisted of 41 symptomatic patients with documented coronary artery disease. A group of apparently healthy subjects with asymptomatic ST segment depression during exercise was divided into two additional groups: Group III, those without coronary artery disease; and Group IV, those with coronary artery disease. Subjects were excluded from the study if they had left ventricular hypertrophy or an intraventricular conduction defect or were taking digitalis or type I antiarrhythmic agents. There were no significant differences in the aT-eT interval and aT-eT/Q-T ratio among the four study groups when compared at rest; however, during exercise at similar heart rates, the aT-eT interval was significantly shorter and the aT-eT/Q-T ratio significantly smaller in Groups II and IV, the subjects with coronary artery disease, than in Group I, the normal subjects. The aT-eT interval and aT-eT/Q-T ratio measurements in Group III did not differ from those in Group I at rest or during exercise. In conclusion, the aT-eT interval and aT-eT/Q-T ratio may reflect changes in myocardial repolarization in exercise-induced ischemia and may have potential for future clinical application.

    Traumatic brain injury (TBI) is a leading cause of sustained impairment in military and civilian populations. However, mild (and some moderate) TBI can be difficult to diagnose due to lack of obvious external injuries and because the injuries are often not visible on conventional acute MRI or CT. Injured brain tissues in TBI patients generate pathological low-frequency neuronal magnetic signal (delta waves 1-4 Hz) that can be measured and localized by magnetoencephalography (MEG). We hypothesize that abnormal MEG delta waves originate from gray matter neurons that experience de-afferentation due to axonal injury to the underlying white matter fiber tracts, which is manifested on diffusion tensor imaging (DTI) as reduced fractional anisotropy. The present study used a neuroimaging approach integrating findings of magnetoencephalography (MEG) and diffusion tensor imaging (DTI), evaluating their utility in diagnosing mild TBI in 10 subjects in whom conventional CT and MRI showed no visible lesions in 9. The results show: (1) the integrated approach with MEG and DTI is more sensitive than conventional CT and MRI in detecting subtle neuronal injury in mild TBI; (2) MEG slow waves in mild TBI patients originate from cortical gray matter areas that experience de-afferentation due to axonal injuries in the white matter fibers with reduced fractional anisotropy; (3) findings from the integrated imaging approach are consistent with post-concussive symptoms; (4) in some cases, abnormal MEG delta waves were observed in subjects without obvious DTI abnormality, indicating that MEG may be more sensitive than DTI in diagnosing mild TBI.

We hypothesize that abnormal MEG delta waves originate from gray matter neurons that experience de-afferentation due to axonal injury to the underlying white matter fiber tracts, which is manifested on diffusion tensor imaging (DTI) as reduced fractional anisotropy. The present study used a neuroimaging approach integrating findings of magnetoencephalography (MEG) and diffusion tensor imaging (DTI), evaluating their utility in diagnosing mild TBI in 10 subjects in whom conventional CT and MRI showed no visible lesions in 9. The results show: (1) the integrated approach with MEG and DTI is more sensitive than conventional CT and MRI in detecting subtle neuronal injury in mild TBI; (2) MEG slow waves in mild TBI patients originate from cortical gray matter areas that experience de-afferentation due to axonal injuries in the white matter fibers with reduced fractional anisotropy; (3) findings from the integrated imaging approach are consistent with post-concussive symptoms; (4) in some cases, abnormal MEG delta waves were observed in subjects without obvious DTI abnormality, indicating that MEG may be more sensitive than DTI in diagnosing mild TBI.

    Free delayed recall is considered the memory measure with the greatest sensitivity for the early diagnosis of dementia. However, its specificity for dementia could be lower, as deficits other than those of pure memory might account for poor performance in this difficult and effortful task. Cued recall is supposed to allow a better distinction between poor memory due to concurrent factors and impairments related to the neurodegenerative process. The available cued recall tests suffer from a ceiling effect. This is a prospective, longitudinal study aiming to assess the utility of a new memory test based on cued recall that avoids the ceiling effect in the early diagnosis of Alzheimer's disease (AD). Twenty-five patients with mild cognitive impairment (MCI), 22 probable AD patients (NINCDS-ADRDA) at a mild stage, 22 elderly patients with subjective memory complaints (SMC) and 38 normal age-matched controls took part in the study. The patients underwent a thorough cognitive evaluation and the recommended screening procedure for the diagnosis of dementia. All patients were re-examined 12-18 months later. A newly devised delayed cued recall test using semantic cues (The RI48 Test) was compared with three established memory tests: the Ten Word-List Recall from CERAD, the "Doors" and the "Shapes" Tests from "The Doors and People Test Battery". Forty-four % of the MCI patients fulfilled criteria for probable AD at follow-up. The RI48 Test classified correctly 88% of the MCI and SMC participants and was the best predictor of the status of MCI and mild AD as well as the outcome of the MCI patients. Poor visual memory was the second best predictor of those MCI patients who evolved to AD. A cued recall test which avoids the ceiling effect is at least as good as the delayed free recall tests in the early detection of AD. PMID:15654553

    New direct-acting antivirals (DAA) for hepatitis C virus (HCV) infection have achieved high cure rates in many patient groups previously considered difficult-to-treat, including those HIV/HCV co-infected. The high price of these medications is likely to limit access to treatment, at least in the short term. Early treatment priority is likely to be given to those with advanced disease, but a more detailed understanding of the potential benefits in treating those with mild disease is needed. We hypothesized that successful HCV treatment within a co-infected population with mild liver disease would lead to a reduction in the use and costs of healthcare services in the 5 years following treatment completion. We performed a retrospective cohort study of HIV/HCV-co-infected patients without evidence of fibrosis/cirrhosis who received a course of HCV therapy between 2004 and 2013. Detailed analysis of healthcare utilization up to 5 years following treatment for each patient using clinical and electronic records was used to estimate healthcare costs. Sixty-three patients were investigated, of whom 48 of 63 (76.2%) achieved sustained virological response 12 weeks following completion of therapy (SVR12). Individuals achieving SVR12 incurred lower health utilization costs (£5,000 per-patient) compared to (£10 775 per-patient) non-SVR patients in the 5 years after treatment. Healthcare utilization rates and costs in the immediate 5 years following treatment were significantly higher in co-infected patients with mild disease that failed to achieve SVR12. These data suggest additional value to achieving cure beyond the prevention of complications of disease.

    Chronic obstructive pulmonary disease (COPD) is a common and often progressive inflammatory disease of the airways that is both preventable and treatable. It is well established that those with mild-to-moderate disease severity represent the majority of patients with COPD, yet this subpopulation is relatively under-studied. Because of an insidious pre-clinical phase, COPD is both under-diagnosed and under-treated. Recent studies have confirmed that even patients with mild, grade 1 COPD [i.e. those with a reduced forced expiratory volume in one second (FEV1)/forced vital capacity ratio but normal FEV1], have measurable physiological impairment with increased morbidity and a higher risk of mortality compared with non-smoking healthy controls. Beyond the imperative of smoking cessation-the pivotal intervention in all COPD stages-the role of pharmacotherapy for prevention of disease progression has yet to be established. The main objective of this review is to provide a concise overview of the heterogeneous pathophysiology of COPD with only mild airway obstruction on spirometry and obstacles for early diagnosis. We emphasize that the absence of sufficiently powered trials involving a large number of patients precludes definitive recommendations in support of (or against) long-term pharmacological treatment in mild COPD. Despite these limitations, we present a rationale for earlier pharmacological intervention derived from recent physiological studies performed in symptomatic patients with mild COPD.

    Focal hand dystonia (FHd) is a recalcitrant, disabling movement disorder, characterized by involuntary co-contractions of agonists and antagonists, that can develop in patients who overuse or misuse their hands. The aim of this study was to document clinical neuromusculoskeletal performance and somatosensory responses (magnetoencephalography) in healthy controls and in FHd subjects with mild versus severe hand dystonia. The performance of healthy subjects (n = 17) was significantly better than that of FHd subjects (n = 17) on all clinical parameters. Those with mild dystonia (n = 10) demonstrated better musculoskeletal skills, task-specific motor performance, and sensory discrimination, but the performance of sensory and fine motor tasks was slower than that of patients with severe dystonia. In terms of somatosensory evoked field responses (SEFs), FHd subjects demonstrated a significant difference in the location of the hand representation on the x and y axes, lower amplitude of SEFs integrated across latency, and a higher ratio of mean SEF amplitude to latency than the controls. Bilaterally,. those with FHd (mild and severe) lacked progressive sequencing of the digits from inferior to superior. On the affected digits, subjects with severe dystonia had a significantly higher ratio of SEF amplitude to latency and a significantly smaller mean volume of the cortical hand representation than those with mild dystonia. Severity of dystonia positively correlated with the ratio of SEF mean amplitude to latency (0.9029 affected, 0.8477 unaffected; p<0.01). The results of the present study strengthen the evidence that patients with FHd demonstrate signs of somatosensory degradation of the hand that correlates with clinical sensorimotor dysfunction, with characteristics of the dedifferentiation varying by the severity of hand dystonia. If these findings represent aberrant learning, then effective rehabilitation must incorporate the principles of neuroplasticity. Training must

    The effects of physical exercise and normalization of serum lipoproteins on stress-induced myocardial ischemia were studied in 18 patients with coronary artery disease, stable angina pectoris, and mild hypercholesterolemia (total serum cholesterol 242 +/- 32 mg/dl). These patients underwent a combined regimen of low-fat/low-cholesterol diet and regular, supervised physical exercise at high intensity for 12 months. At 1 year serum lipoproteins has been lowered to ideal levels (serum cholesterol 202 +/- 31 mg/dl, low-density lipoproteins 130 +/- 30 mg/dl, very low-density lipoproteins 22 +/- 15 mg/dl, serum triglycerides 105 (69 to 304) mg/dl) and physical work capacity was improved by 21% (p less than .01). No significant effect was noted on high-density lipoproteins, probably as a result of the low-fat/high-carbohydrate diet. Stress-induced myocardial ischemia, as assessed by thallium-201 scintigraphy, was decreased by 54% (p less than .05) despite higher myocardial oxygen consumption. Eighteen patients matched for age and severity of coronary artery disease served as a control group and ''usual medical care'' was rendered by their private physicians. No significant changes with respect to serum lipoproteins, physical work capacity, maximal rate-pressure product, or stress-induced myocardial ischemia were observed in this group. These data indicate that regular physical exercise at high intensity, lowered body weight, and normalization of serum lipoproteins may alleviate compromised myocardial perfusion during stress.

    Our objective is to elucidate the association of baseline perfusion lesion volume on perfusion-weighted magnetic resonance imaging (PWI) obtained at hyperacute stage of ischemic stroke with subsequent cerebral ischemic events (SIEs) in patients with symptomatic steno-occlusion of major cerebral arteries. Using a prospective stroke registry database, patients arriving within 24 hours of onset with symptomatic steno-occlusion of major supratentorial cerebral arteries were identified. On baseline PWI, time-to-peak lesion volume (TTP-LV) was determined by a simple geometric method and dichotomized into the highest tertile (large) and the other tertiles (small to medium) according to the vascular territory of occluded arteries. Primary outcome was a time to SIE up to 1 year after stroke onset. A total of 385 patients (a median time delay from onset to arrival, 2.2 hours) were enrolled. During the first year of stroke, the SIE rate of the large TTP-LV group was twice that of the small-to-medium TTP-LV group (35.7% versus 17.4%; P < .001). Large TTP-LV independently raised the hazard of SIE (hazard ratio, 2.24; 95% confidence interval, 1.45-3.44). This study demonstrates that TTP-LV on PWI measured through a simple geometric method at an emergency setting can be used to predict progression or recurrence of ischemic stroke in patients with symptomatic steno-occlusion of major cerebral arteries.

    Although diabetes mellitus (DM) is known to increase the risk of hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC), the impact of dynamic glucose status on HCC occurrence in chronic hepatitis C (CHC) patients receiving antiviral therapy is unclear. In total, 1112 biopsy-proven patients treated with peginterferon/ribavirin were enrolled in this study. Both pretreatment and post-treatment glucose status, including 75 g oral glucose tolerance test (OGTT), were measured to evaluate the association between glucose status and the development of HCC. Of the 1112 patients evaluated, 93 (8.4%) developed HCC >5183.8 person-years of follow-up (annual incidence rate: 1.79%). DM only influenced the risk of developing CC in patients with mild liver disease (F0-2) and a sustained virological response (SVR) but not in other patient subpopulations. Cox-regression analysis demonstrated that the strongest factor associated with HCC in patients with mild liver disease and SVR was the presence of DM (hazard ratio [HR]/95 % confidence intervals [CI]: 3.79/1.420-10.136, P = 0.008), followed by age (HR/CI: 1.06/1.001-1.117, P = 0.046) and platelet count (HR/CI: 0.989/0.979-1.000, P = 0.05). The percentages of SVR patients with F0-2 with normoglycemia, pre-DM, sub-DM (pre-sDM), and DM before treatment were 45.3% (n = 267), 29.9% (n = 176), 15.6% (n = 92), and 9.2% (n = 54), respectively. The percentages of HCC in patients with normoglycemia, pre-sDM, and DM were 1.1%, 3.7%, and 11.1%, respectively (trend P < 0.001). Sixteen of the 19 (84.2 %) HCC patients possessed glucose abnormality (including 6 patients with DM and 10 patients with pre-sDM) before antiviral therapy. Compared to patients with normoglycemia, the incidence of HCC increased gradually from pre-sDM (HR: 3.6, P = 0.05) to DM (HR: 11.6, P = 0.001) (adjusted trend P = 0.004). We concluded that DM is a critical determinant for the development of HCC in SVR patients with mild liver disease. Pre-sDM status

    Several studies have shown excess risk for a number of comorbidities in patients with psoriasis compared with the general population, but data on cause-specific mortality in this patient population are limited. The aim of this study was to estimate the associations of psoriasis and 12 specific causes of death and all-cause mortality in patients with mild and severe psoriasis. The study was based on data from Swedish administrative registers and compared the risk of death in 39,074 patients with psoriasis with 154,775 sex-, age- and residency-matched referents using Cox proportional hazards models. In patients with mild and severe psoriasis, the strongest associations were observed for deaths due to kidney disease (hazard ratio [HR]=2.20, p < 0.01) and liver disease (HR = 4.26, p < 0.001), respectively. Whilst cardiovascular disease was the main driver of excess mortality in absolute terms, the risks for other causes of death were also substantially elevated in patients with psoriasis compared with matched referents.

    Little is known about injury of the arcuate fasciculus (AF) in patients with mild traumatic brain injury (TBI). We investigated injury of the AF in the dominant hemisphere in patients with mild TBI, using diffusion tensor tractography (DTT). We recruited 25 patients with injury of the left AF among 64 right-handed consecutive patients with mild TBI and 20 normal control subjects. DTTs of the left AF were reconstructed, and fractional anisotropy (FA), apparent diffusion coefficient (ADC), and fiber number of the AF were measured. Among 64 consecutive patients, 25 (39%) patients showed injury of the left AF. The patient group showed lower FA value and fiber number with higher ADC value than the control group (P < 0.05). On K-WAB evaluation, aphasia quotient and language quotient were 95.9 ± 4.1 (range 85-100) and 95.0 ± 5.4 (range 80-100), respectively. However, 23 (92.0%) of 25 patients complained of language-related symptoms after TBI; paraphasia in 12 (48.0%) patients, deficits of comprehension in 4 (16.0%) patients, deficits of speech production in 1 (4.0%) patient, and >2 language symptoms in 6 (24.0%) patients. We found that a significant number (39%) of patients with mild TBI had injury of the AF in the dominant hemisphere and these patients had mild language deficit. These results suggest that DTT could provide useful information in detecting injury of the AF and evaluation of the AF using DTT would be necessary even in the case of a patient with mild TBI who complains of mild language deficit.

    Language batteries used to assess the skills of elderly individuals, such as naming and semantic verbal fluency, present some limitations in differentiating healthy controls from patients with amnestic mild cognitive impairment (a-MCI). Deficits in narrative discourse occur early in dementia caused by Alzheimer's disease (AD), and the narrative discourse abilities of a-MCI patients are poorly documented. The present study sought to propose and evaluate parameters for investigating narrative discourse in these populations. After a pilot study of 30 healthy subjects who served as a preliminary investigation of macro- and micro-linguistic aspects, 77 individuals (patients with AD and a-MCI and a control group) were evaluated. The experimental task required the participants to narrate a story based on a sequence of actions visually presented. The Control and AD groups differed in all parameters except narrative time and the total number of words recalled. The a-MCI group displayed mild discursive difficulties that were characterized as an intermediate stage between the Control and AD groups' performances. The a-MCI and Control groups differed from the AD group with respect to global coherence, discourse type and referential cohesion. The a-MCI and AD groups were similar to one another but differed from the Control group with respect to the type of words recalled, the repetition of words in the same sentence, the narrative structure and the inclusion of irrelevant propositions in the narrative. The narrative parameter that best distinguished the three groups was the speech effectiveness index. The proposed task was able to reveal differences between healthy controls and groups with cognitive decline. According to our findings, patients with a-MCI already present narrative deficits that are characterized by mild discursive difficulties that are less severe than those found in patients with AD.

    The aim of this study was to explore the relationship between abnormality on susceptibility-weighted imaging (SWI) and newly-developed depression after mild traumatic brain injury. The study registered 200 patients with closed TBI and normal finding at CT and conventional MRI. All patients underwent MRI including conventional MR sequences and SWI. The number and volume of microbleed lesions were semi-automatically outlined and manually counted. All patients were followed up with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-IV) within 1 year after TBI. The difference in microbleed lesions on SWI was compared between the depressive and non-depressive groups. The depressive group had a higher rate of abnormality on SWI than did the non-depressive group (p < 0.001). Among patients that had exhibited microbleed lesions, the number and volume of lesions were greater in the depressive group than the non-depressive group (both p < 0.001). These differences in numbers and volume of lesions were found only at the frontal, parietal and temporal lobes (all p < 0.001). Among patients that had exhibited microbleed lesions, the number and volume of lesions in other areas were not significantly different between the depressive and non-depressive groups (all p > 0.05). In conclusion, SWI was useful to identify the microbleed lesions after mild TBI. The distribution range and location of microbleed lesions were correlated with depression after TBI.

    Traumatic brain injury (TBI) is a leading cause of sustained impairment in military and civilian populations. However, mild (and some moderate) TBI can be difficult to diagnose because the injuries are often not detectable on conventional MRI or CT. Injured brain tissues in TBI patients generate abnormal low-frequency magnetic activity (ALFMA, peaked at 1-4 Hz) that can be measured and localized by magnetoencephalography (MEG). We developed a new automated MEG low-frequency source imaging method and applied this method in 45 mild TBI (23 from combat-related blasts, and 22 from non-blast causes) and 10 moderate TBI patients (non-blast causes). Seventeen of the patients with mild TBI from blasts had tertiary injuries resulting from the blast. The results show our method detected abnormalities at the rates of 87% for the mild TBI group (blast-induced plus non-blast causes) and 100% for the moderate group. Among the mild TBI patients, the rates of abnormalities were 96% and 77% for the blast and non-blast TBI groups, respectively. The spatial characteristics of abnormal slow-wave generation measured by Z scores in the mild blast TBI group significantly correlated with those in non-blast mild TBI group. Among 96 cortical regions, the likelihood of abnormal slow-wave generation was less in the mild TBI patients with blast than in the mild non-blast TBI patients, suggesting possible protective effects due to the military helmet and armor. Finally, the number of cortical regions that generated abnormal slow-waves correlated significantly with the total post-concussive symptom scores in TBI patients. This study provides a foundation for using MEG low-frequency source imaging to support the clinical diagnosis of TBI. PMID:22542638

    Background and Objectives: The relationship between leiomyoma and endometriosis is poorly understood. Both contribute to considerable pain and may cause subfertility or infertility in women. We conducted this retrospective study to assess the rate of coexistence of endometriosis in women with symptomatic leiomyoma. The primary outcome measured was the coexistence of histology-proven endometriosis in women with symptomatic leiomyoma. Methods: This is a retrospective review of a data-based collection of medical records of 244 patients treated at a tertiary medical center, who were evaluated for symptomatic leiomyoma from March 2011 through December 2015. Of those, 208 patients underwent laparoscopic or laparoscopic-assisted myomectomy or hysterectomy. All patients provided consent for possible concomitant diagnosis and treatment of endometriosis. The remaining 36 patients underwent medical therapy and were excluded from the study. All patients who had myomectomy or supracervical hysterectomy underwent minilaparotomy for extracorporeal morcellation and specimen removal beginning in April 2012. Results: Of the 208 patients with the presenting chief concern of symptomatic leiomyoma and who underwent surgical therapy, 181 had concomitant diagnoses of leiomyoma and endometriosis, whereas 27 had leiomyoma. Of the 27 patients, 9 also had adenomyosis. Patients with only fibroid tumors were, on average, 4.0 years older than those with endometriosis and fibroids (mean age, 44 vs 40 ± SD). Patients with both pathologies were also more likely to present with pelvic pain and nulliparity than those with fibroid tumors alone. Conclusions: In our patient population, 87.1% of patients with a chief concern of symptomatic fibroids also had a diagnosis of histology-proven endometriosis, which affirms the need for concomitant diagnosis and intraoperative treatment of both conditions. Overlooking the coexistence of endometriosis in women with symptomatic leiomyoma may lead to suboptimal

    Background Wilson’s disease (WD) evolves rapidly and is fatal if untreated. The treatment of WD patients with mild liver disease is not clearly defined. To address this issue, we evaluated long-term outcomes of three treatment regimens (D-penicillamine, zinc or both) in patients diagnosed in childhood. Methods We retrospectively evaluated efficacy, compliance and reasons for treatment discontinuation in 42 WD patients (median age at diagnosis: 6 years; median follow-up: 12 years) with mild liver disease. Treatment duration for each treatment block until a medication change or completion of follow-up was analyzed. Events of change of treatment were evaluated using Kaplan-Meier analysis. Results Total discontinuations due to treatment failure or adverse events were more frequent in patients receiving D-penicillamine (45%) or combination (36%) therapy than in patients receiving zinc (12%) (P = .001 and P = .02, respectively). Treatment failure was more frequent on D-penicillamine (28%) and combination therapy (36%) than on zinc (12%); the difference was statistically significant only between zinc and combination therapy (P = .03). First-line zinc monotherapy controlled WD-related liver disease in 13/15 patients (87%); the two subjects that failed on zinc were poor adherent. Zinc was effective in 3/5 (60%) patients that failed on D-penicillamine and combination regimens. All 15 D-penicillamine responders that switched to zinc had good control of liver disease at a median follow-up of 13.1 years. Among 6 D-penicillamine non-responders that switched to zinc, 4 (67%) responded. At follow-up completion, only 5/42 (12%) patients failed. Adverse event-induced discontinuation was significantly more frequent in patients on D-penicillamine than in patients receiving zinc (P = .03). Conclusions Zinc monotherapy is effective in controlling WD-related liver disease both as first-line and as maintenance treatment in patients with mild liver disease diagnosed in

    Duchenne muscular dystrophy (DMD) is an X-linked recessive disease caused by mutations in the dystrophin gene and is characterized by muscle degeneration and death. DMD affects males; females being asymptomatic carriers of mutations. However, some of them manifest symptoms due to a translocation between X chromosome and an autosome or to a heterozygous mutation leading to inactivation of most of their normal X chromosome. Six symptomatic female carriers and two asymptomatic were analyzed by: I) Segregation of STRs-(CA)n and MLPA assays to detect a hemizygous alteration, and II) X chromosome inactivation pattern to uncover the reason for symptoms in these females. The symptomatic females shared mild but progressive muscular weakness and increased serum creatin kinase (CK) levels. Levels of dystrophin protein were below normal or absent in many fibers. Segregation of STRs-(CA)n revealed hemizygous patterns in three patients, which were confirmed by MLPA. In addition, this analysis showed a duplication in another patient. X chromosome inactivation assay revealed a skewed X inactivation pattern in the symptomatic females and a random inactivation pattern in the asymptomatic ones. Our results support the hypothesis that the DMD phenotype in female carriers of a dystrophin mutation has a direct correlation with a skewed X-chromosome inactivation pattern.

    Gingivitis in traditional national dentistry referred to independent diseases or symptomatic condition in periodontitis and classified morphologically. The diagnostic features of the diseases are characteristic, but the clinical presentation of symptomatic gingivitis and patterns of bone destructions may vary between patients. Successful treatment of the disease depends from proper diagnosis and advanced disease stages, but for symptomatic gingivitis that accompanying chronic periodontitis, protocols include surgical excision. Despite of the high prevalence of chronic generalized periodontitis, its active treatment often start in severe destruction and bone loss (2-3 stage severity). Today etiotropic antimicrobial therapy is real way to control microbial biofilm and has solid evidence base. Applying of etiotropic antimicrobial therapy as systemic azithromycin with timely treatment of mild to moderate periodontal and bone destruction may reduce severe periodontitis incidence of and treatment-related complications in the future. This paper attempts to describe the clinical diagnostic features and the current treatment options along with a suggested protocol for comprehensive management of chronic generalized periodontitis and hypertrophic gingivitis patient with case reports and a brief review.

    In adults, mild traumatic brain injury (MTBI) frequently results in impairments of cognitive functions which would lead to psychological consequences in the future. Cerebrolysin is a nootropic drug, and can significantly improve cognitive function in patients with Alzheimer's disease and stroke. The purpose of this study was to investigate how Cerebrolysin therapy enhances cognitive recovery for mild traumatic brain injury patients using a double-blinded, placebo-controlled, randomized phase II pilot study. Patients having head injury within 24 h sent to our hospital were screened and recruited if patients were alert and conscious, and had intracranial contusion haemorrhage. From July 2009 to June 2010, totally, thirty-two patients were recruited in the double-blinded, placebo-controlled, and randomized study. Patients were randomized to receive Cerebrolysin (Group A, once daily intravenous infusion of 30 mL Cerebrolysin over a 60-min period for 5 days) or placebo (Group B, same dosage and administration of normal saline as Group A). The primary outcome measures were differences of cognitive function including Mini-Mental Status Examination (MMSE), and Cognitive Abilities Screening Instrument (CASI) scores between baseline and week 1, between baseline and week 4, and between baseline and week 12. Thirty-two patients completed the trial. For Group A, the CASI score difference between baseline and week 12 was 21.0 ± 20.4, a significantly greater change than that of Group B (7.6 ± 12.1) (p = 0.0461). Besides, drawing function (one of the domains of CASI; p = 0.0066) on week 4 and both drawing function (p = 0.0472) and long-term memory (one of the domains of CASI; p = 0.0256) on week 12 were also found to be significantly improved in the patients receiving Cerebrolysin treatment. Our results suggest that Cerebrolysin improves the cognitive function of the MTBI in patients at 3rd month after injury, especially for long-term memory and drawing function.

    Background: Diagnosis of spontaneous bacterial peritonitis in cirrhosis can be made when a patient has an ascites polymorphonuclear leukocyte count ≥250/mm3. However, symptomatic bacterascites, which is a variant of spontaneous bacterial peritonitis with signs of infection but an ascites polymorphonuclear leukocyte count <250/mm3, cannot be confirmed until the time-consuming ascites culture becomes positive. Currently, early indicators for symptomatic bacterascites remain undetermined. Aims: To develop a quick screening model for early detection of symptomatic bacterascites in cirrhosis. Materials and Methods: Data on patients with cirrhotic ascites from two hospitals (from 2010 to 2014) were collected retrospectively. Patients with symptomatic bacterascites were enrolled in the case group and compared with patients without any infection in the control group. Logistic regression analysis was used to build a model for screening symptomatic bacterascites, and a receiver operating characteristics curve was used to assess the model. Results: In total, 103 patients were enrolled in the case group and 204 patients were enrolled in the control group. A screening model was constructed based on body temperature, abdominal tenderness, blood neutrophil percentage, blood total bilirubin, prothrombin time, and ascites nucleated leukocyte count. The area under the receiver operating characteristic curve was 0.939; a screening score of 0.328 was the best cutoff value. Conclusion: Patients with suspected symptomatic bacterascites can be quickly screened according to the developed model, and a screening score ≥0.328 indicates symptomatic bacterascites.

    BACKGROUND Latrepirdine is an orally administered experimental small molecule that was initially developed as an antihistamine and subsequently was shown to stabilize mitochondrial membranes and function, which might be impaired in Huntington disease. OBJECTIVE To determine the effect of latrepirdine on cognition and global function in patients with mild to moderate Huntington disease. DESIGN Randomized, double-blind, placebo-controlled study. SETTING Sixty-four research centers in Australia, Europe, and North America. PATIENTS Four hundred three patients with mild to moderate Huntington disease and baseline cognitive impairment (Mini-Mental State Examination score, 10-26). INTERVENTION Latrepirdine (20 mg) vs matching placebo administered orally 3 times daily for 26 weeks. MAIN OUTCOME MEASURES The co-primary outcome measures were cognition as measured by the change in Mini-Mental State Examination score from baseline to week 26 and global function at week 26 as measured by the Clinician Interview-Based Impression of Change, plus carer interview, which ranges from 1 (marked improvement) to 7 (marked worsening). Secondary efficacy outcome measures included behavior, daily function, motor function, and safety. RESULTS The mean change in Mini-Mental State Examination score among participants randomized to latrepirdine (1.5-point improvement) did not differ significantly from that among participants randomized to placebo (1.3-point improvement) (P=.39). Similarly, the distribution of the Clinician Interview-Based Impression of Change, plus carer interview did not differ significantly among those randomized to latrepirdine compared with placebo (P=.84). No significant treatment effects were detected on the secondary efficacy outcome measures. The incidence of adverse events was similar between those randomized to latrepirdine (68.5%) and placebo (68.0%).

    The study aimed to develop pre-clinical diagnosis of Alzheimer's disease (AD) and - in future - preventive therapy in patients with mild cognitive impairment (MCI). The MCI group (n=44) and AD group (n=42, including 18 patients with soft dementia and 24 patients with mild dementia) were studied. The groups were matched for age (median 70 and 69 years for MCI and AD groups, respectively). The control group comprised 24 mentally healthy relatives of the patients. Correlations between the activity/amounts of platelet enzymes: cytochrome c-oxidase (COX), glutamine synthetase-like protein (GSLP) and the extent of cognitive impairment were studied. The COX activity in MCI and AD groups was significantly lower than in the control group (Kruskal-Wallis test p=0.0001, χ²=11.6, p=0.003). These tests showed significant differences in GSLP amount between three groups (p=0.04 and χ²=9.38, p=0.01, respectively). Significant reverse correlation (Spearman R= -0.43, p=0.007) was found between GSLP amount and MMSE scores for MCI+AD group, i.e., the lower MMSE scores, the higher platelet GSLP level. Platelet COX and GSLP may be considered as early markers of cognitive impairment.

    Background The purpose of this study was to evaluate the effects of caprylic triglyceride (CT) in patients with mild-to-moderate Alzheimer’s disease (AD) in routine clinical practice via review of medical records and caregiver questionnaires. Methods Participants were outpatients aged ≥50 years with a diagnosis of probable mild-to-moderate AD who had received CT for ≥6 months. The primary outcome was change from baseline in the patient’s condition as rated by the treating physician using a physician’s overall assessment. Results A total of 55 patients were included. The physician’s overall assessment indicated that ~80% of patients who had CT added to ongoing pharmacotherapy were stable or improved. Mini-Mental State Examination scores also remained stable over 15 months of therapy (20.6 ± 3.0 at baseline and 20.1 ± 5.6 at follow-up, P = 0.5233, n = 27). Caregiver assessments indicated that most patients were stable or improved with respect to memory and ability to carry out activities of daily living. The most frequent adverse events with CT involved the gastrointestinal system. Conclusion Results from this chart review indicate that addition of CT to pharmacotherapy was associated with stable disease or improvement over a follow-up period of 18.8 months. PMID:24187497

    Fingolimod-related bradycardia is usually asymptomatic, reaches its nadir within 6 hours post-dose and recovers spontaneously. Here we report the case of a 30-year-old MS patient with vagotonia who developed symptomatic bradycardia with 33 beats per minute at nadir 39 hours after a single dose of fingolimod. Bradycardia was responsive to atropine, but returned within 2 hours. Overall, it took a week until the patient recovered. Extended monitoring is advised in patients with symptomatic bradycardia.

    Background/Aims The purpose of our study was to evaluate vascular risk factors and other clinical variables as predictors of cognitive and functional decline in elderly patients with mild to moderate dementia. Methods The clinical characteristics of 82 elderly patients (mean age 79.0 ± 5.9 years; 67.1% females) with mild to moderate dementia were obtained at baseline, including years of education, Framingham Coronary Heart Disease Risk score, Hachinski Ischemic Score (HIS), Clinical Dementia Rating (CDR), Mini-Mental State Examination (MMSE) score, Functional Activities Questionnaire (FAQ) score, Burden Interview Scale score, and Neuropsychiatric Inventory (NPI) score. Changes in MMSE and FAQ scores over time were assessed annually. The association between baseline clinical variables and cognitive and functional decline was investigated during 3 years of follow-up through the use of generalized linear mixed effects models. Results A trend was found towards steeper cognitive decline in patients with less vascular burden according to the HIS (β = 0.056, p = 0.09), better cognitive performance according to the CDR score (β = 0.313, p = 0.06) and worse caregiver burden according to the Burden Interview Scale score (β = −0.012, p = 0.07) at baseline. Conclusion Further studies with larger samples are necessary to confirm and expand our findings. PMID:25493090

    Patients with Alzheimer disease (AD) report pain less frequently than their cognitively intact peers. It has been hypothesized that pain processing is altered in AD. The aim of this study was to investigate agreement and reliability of 3 pain sensitivity tests and to examine pain threshold and tolerance in patients with AD. We examined 29 patients with mild to moderate AD and 29 age- and gender-matched healthy control subjects with quantitative sensory testing, ie, assessments of detection threshold (warmth detection threshold [WDT]) and pain threshold (heat pain threshold [HPT], pressure algometry, cold pressor test), and assessments of tolerance (pressure algometry, cold pressor test). All procedures were done twice on day 1, 1 hour apart, and repeated on day 2. We found no difference between groups for WDT (patient vs control subjects: mean [95% confidence interval]: 35.5°C [33.4°C to 37.6°C] vs 35.4°C [34.3°C to 36.5°C], P=.8) or HPT (41.2°C [40.0°C to 42.4°C] vs 42.3°C [41.1°C to 43.5°C], P=.24). We observed comparable thresholds for pressure algometry (median [25% to 75% interquartile range]: 120 kPa [100 to 142 kPa] vs 131 kPa [113 to 192 kPa], P=.10), but significantly lower tolerance in AD patients (213 kPa [188 to 306 kPa] vs 289 kPa [262 to 360 kPa], P=.008). No differences were found for the cold pressor test. The study demonstrated good replicability of the sensory testing data with comparable data variability, for both groups, which supports the use of these methods in studies of patients with mild to moderate AD. Contrary to previous studies, we observed a reduced pain tolerance in patients with mild to moderate AD, which suggests that the reduced report of pain cannot be explained by reduced processing of painful stimuli.

    Increase of factor VIII activity (FVIII) after physical exercise has been reported in healthy subjects and small-scale studies in patients with coagulopathies. The aim was to study whether moderate and mild haemophilia A patients are able to increase their endogenous FVIII activity levels by physical activity. We studied changes in FVIII activity levels after high-intensity exercise in 15 haemophilia A patients, 20-39 years, eight with moderate, seven with mild haemophilia. Patients cycled until volitional exhaustion, blood samples were drawn before and 10 min after the exercise test. FVIII activity increased 2.5 times (range 1.8-7.0 times), for both severities. Absolute increases were markedly different: median 7 IU dL(-1) (range 3-9 IU dL(-1) ) in patients with moderate, compared to 15 IU dL(-1) (range 6-62 IU dL(-1) ) in mild haemophilia patients. VWF and VWFpp increased independently of severity; median 50% (range 8-123%) and median 165% (range 48-350%), respectively, reflecting acute release of VWF. These observations may be used to promote high-intensity activities before participating in sports for moderate and mild haemophilia A patients, to reduce bleeding risk. Further studies are warranted to fully appreciate the clinical significance of exercise on different levels of intensity in patients with mild and moderate haemophilia A.

    2012-01-01

    Background Mild acquired cognitive impairment (MACI) is a new term used to describe a subgroup of patients with mild cognitive impairment (MCI) who are expected to reach a stable cognitive level over time. This patient group is generally young and have acquired MCI from a head injury or mild stroke. Although the past decade has seen a large amount of research on how to use information and communication technology (ICT) to support self-management of patients with chronic diseases, MACI has not received much attention. Therefore, there is a lack of information about what tools have been created and evaluated that are suitable for self-management of MACI patients, and a lack of clear direction on how best to proceed with ICT tools to support self-management of MACI patients. Objective This paper aims to provide direction for further research and development of tools that can support health care professionals in assisting MACI patients with self-management. An overview of studies reporting on the design and/or evaluation of ICT tools for assisting MACI patients in self-management is presented. We also analyze the evidence of benefit provided by these tools, and how their functionality matches MACI patients’ needs to determine areas of interest for further research and development. Methods A review of the existing literature about available assistive ICT tools for MACI patients was conducted using 8 different medical, scientific, engineering, and physiotherapy library databases. The functionality of tools was analyzed using an analytical framework based on the International Classification of Functioning, Disability and Health (ICF) and a subset of common and important problems for patients with MACI created by MACI experts in Sweden. Results A total of 55 search phrases applied in the 8 databases returned 5969 articles. After review, 7 articles met the inclusion criteria. Most articles reported case reports and exploratory research. Out of the 7 articles, 4 (57

    Understanding how memory breaks down in the earliest stages of Alzheimer's disease (AD) process has significant implications, both clinically and with respect to intervention development. Previous work has highlighted a robust picture superiority effect in patients with amnestic mild cognitive impairment (aMCI). However, it remains unclear as to how pictures improve memory compared to words in this patient population. In the current study, we utilized receiver operating characteristic (ROC) curves to obtain estimates of familiarity and recollection for pictures and words in patients with aMCI and healthy older controls. Analysis of accuracy shows that even when performance is matched between pictures and words in the healthy control group, patients with aMCI continue to show a significant picture superiority effect. The results of the ROC analysis showed that patients demonstrated significantly impaired recollection and familiarity for words compared controls. In contrast, patients with aMCI demonstrated impaired recollection, but intact familiarity for pictures, compared to controls. Based on previous work from our lab, we speculate that patients can utilize the rich conceptual information provided by pictures to enhance familiarity, and perceptual information may allow for post-retrieval monitoring or verification of the enhanced sense of familiarity. Alternatively, the combination of enhanced conceptual and perceptual fluency of the test item might drive a stronger or more robust sense of familiarity that can be accurately attributed to a studied item.

    Using three-dimensional (3D) telomeric analysis of buccal cells of 82 Alzheimer's disease (AD) patients and cognitively normal age and gender-matched controls, we have for the first time examined changes in the 3D nuclear telomeric architecture of buccal cells among levels of AD severity based on five 3D parameters: i) telomere length, ii) telomere number, iii) telomere aggregation, iv) nuclear volume, and v) a/c ratio, a measure of spatial telomere distribution. Our data indicate that matched controls have significantly different 3D telomere profiles compared to mild, moderate, and severe AD patients (p < 0.0001). Distinct profiles were also evident for each AD severity group. An increase in telomere number and aggregation concomitant with a decrease in telomere length from normal to severe AD defines the individual stages of the disease (p < 0.0001).

    Background: Olfactory dysfunction (OD) is a disorder associated with traumatic brain injury (TBI), which is prevalent in up to 20% of patients suffering from TBI. Nevertheless, most studies focusing on the relationship between OD and TBIs do not differentiate between the different types of TBI (mild, medium, and severe). In this paper, we conducted a comprehensive and systematic review of the existing literature for the association between mild TBI (mTBI) and OD in order to examine their relationship, focusing on its neurosurgical management and the radiographic characteristics. Methods: The MEDLINE database was systematically reviewed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. We found 66 articles, of which 10 fulfilled our criteria. Results: All except two studies reported a significant association between trauma severity and olfaction. Two studies found a negative correlation between TBI severity and olfactory bulb volume with one reporting an r value of −0.62). Three studies reported an association between the observation of radiographic intracranial hemorrhage or skull base fractures and the history of TBI. Conclusion: According to our search results, we conclude that OD is a prevalent but underdiagnosed problem in mTBI. Because OD is associated with a significant decrease in quality of life, we think that neurosurgical teams need to asses olfactory function in mTBI patients when they report to clinics. To illustrate this scenario, we include two distinct cases of patients with anosmia after mTBI in this review. Finally, we suggest a treatment algorithm for patients with mTBI so that a possible OD can be diagnosed and treated as early as possible. PMID:27213113

    PurposeOsteoarthritis is a common cause of pain and disability. Mild to moderate knee osteoarthritis that is resistant to nonsurgical options and not severe enough to warrant joint replacement represents a challenge in its management. On the basis of the hypothesis that neovessels and accompanying nerves are possible sources of pain, previous work demonstrated that transcatheter arterial embolization for chronic painful conditions resulted in excellent pain relief. We hypothesized that transcatheter arterial embolization can relieve pain associated with knee osteoarthritis.MethodsTranscatheter arterial embolization for mild to moderate knee osteoarthritis using imipenem/cilastatin sodium or 75 μm calibrated Embozene microspheres as an embolic agent has been performed in 11 and three patients, respectively. We assessed adverse events and changes in Western Ontario and McMaster University Osteoarthritis Index (WOMAC) scores.ResultsAbnormal neovessels were identified within soft tissue surrounding knee joint in all cases by arteriography. No major adverse events were related to the procedures. Transcatheter arterial embolization rapidly improved WOMAC pain scores from 12.2 ± 1.9 to 3.3 ± 2.1 at 1 month after the procedure, with further improvement at 4 months (1.7 ± 2.2) and WOMAC total scores from 47.3 ± 5.8 to 11.6 ± 5.4 at 1 month, and to 6.3 ± 6.0 at 4 months. These improvements were maintained in most cases at the final follow-up examination at a mean of 12 ± 5 months (range 4–19 months).ConclusionTranscatheter arterial embolization for mild to moderate knee osteoarthritis was feasible, rapidly relieved resistant pain, and restored knee function.

    Our aim was to study associations between serum fibrinogen and C-reactive protein (CRP) levels and respiratory parameters on polysomnography (PSG) in patients with snoring as their main complaint and compromised upper airway anatomy. In this retrospective study, consecutive patients (43 female and 132 male; age range 11-82 years, respiratory distress index-RDI range 0.1-94.4/h) with snoring as their main complaint and compromised upper airway anatomy who underwent PSG were assessed. Spearman's Rho coefficients between RDI, AI (apnea index), hypopnea index (HI), average and lowest SpO2 (in %) and CRP- and fibrinogen serum levels were calculated. Comparisons between groups were made using Wilcoxon-W test. Patients with CRP > 5 mg/dl (22 % of the cohort) had significantly increased RDI, AI, average and lowest SpO2 than patients with CRP < 5 mg/dl. Increased correlation coefficients were observed for average SpO2 (-0.386), RDI (0.355), lowest SpO2 (-0.323) and AI (0.309). Patients with fibrinogen >350 mg/dl (in 33 %) had significantly increased RDI, HI, AI, average and lowest SpO2 than patients with fibrinogen <350 mg/dl. Increased correlation coefficients were found for average (-0.340) and lowest (-0.268) SpO2, RDI (0.236) and AI (0.229). Even patients with RDI < 15/h had increased serum CRP-(in 11 %) and/or fibrinogen-(in 19 %) levels. Simultaneous elevation of both CRP and fibrinogen levels occurred only in patients with RDI > 5/h. Systemic inflammation is strongly associated with average and lowest SpO2, RDI and AI (and with HI) in snorers with compromised upper airway anatomy and is present even in patients with primary snoring and mild obstructive sleep apnea.

    OBJECTIVE: To evaluate the efficacy and safety of the second generation dihydropyridine calcium channel blocker lacidipine in patients with heart failure. DESIGN: Placebo controlled, parallel group, double blind study over 8 weeks. SETTING: General community hospital in Breda, The Netherlands. PATIENTS: A random sample was studied of 25 outpatients with symptoms of mild to moderate heart failure, despite treatment with diuretics, digoxin, and angiotensin converting enzyme inhibitors. Their mean age was 65 years, with mean left ventricular ejection fraction of 0.24 and a peak oxygen consumption of 14.4 ml/min/kg. Two patients dropped out on lacidipine, one patient on placebo. INTERVENTION: Treatment with lacidipine 4 mg once daily or placebo for eight weeks. MAIN OUTCOME MEASURE: Cardiopulmonary exercise testing, invasive haemodynamics, and plasma neurohormones. RESULTS: Treatment with lacidipine 4 mg once daily, as compared to placebo treatment, significantly improved peak oxygen consumption (P < 0.02), cardiac index (P < 0.01), and stroke volume (P < 0.03) paralleled by a decrease in systemic vascular resistance (P < 0.03) and arteriovenous oxygen content difference (P < 0.01). Plasma noradrenaline, plasma renin activity, and aldosterone values did not differ between lacidipine and placebo. CONCLUSIONS: This second generation dihydropyridine may be of value as an adjunct to standard treatment in congestive heart failure patients. PMID:8673754

    Recently, middle-aged men who have begun frequently complaining of erectile dysfunction and nonspecific symptoms similar to those of postmenopausal women, visited a male climacterium clinic in Japan. Some patients, who were already taking antihypertensive medication, discontinued or reduced their dosages of antihypertensive medication after anti-depressant therapy. Forty-nine males over the age of 40 years were studied to evaluate the relationships between blood pressure, mental stress, and testosterone levels. The systemic blood pressure (sBP) of 24 patients was higher than the criteria for mild hypertension: 140/90 mmHg (HT group) at first visit. The sBP of the other 25 patients was normal (N group). The international index of erectile function (IIEF5) score (normal >21), self-rating depression scale (SDS) score (normal <40), and plasma testosterone levels were also evaluated before and after anti-depressant therapy without androgen replacement therapy. There were no significant differences between the groups in IIEF5 or SDS scores. The plasma testosterone levels in the HT group at first visit were significantly lower than those in the N group (230+/-77 vs. 343+/-92 ng/dL, p<0.001). After treatment, the IIEF5 scores were unchanged, whereas SDS scores were lower in both groups. Mean systemic blood pressure (mBP) in the HT group significantly decreased from 112+/-7 to 94+/-7 mmHg after treatment, concomitant with the disappearance of nonspecific complaints and the increase of testosterone levels. In the N group, however, neither mBP nor testosterone levels changed. Psychotherapy can ameliorate mild systemic hypertension in climacteric men with low testosterone levels. Mental stress might suppress the hypothalamic-pituitary-gonadal axis to decrease testosterone levels.

    Atorvastatin, a second generation synthetic 3-hydroxy 3-methylglutaryl-coenzyme-A (HMG-CoA) reductase inhibitor used in the treatment of hypercholesterolemia, reduces both intracellular cholesterol synthesis and serum cholesterol levels, and this could have a potential negative impact on gonadal and adrenal steroidogenesis. Hypercholesterolemia in type 2 diabetes, even when mild, must be treated in an aggressive way, due to the more strict therapeutic goals than in the non diabetic population. Since the wide use of 3-hydroxy 3-methylglutaryl-coenzyme-A (HMG-CoA) reductase inhibitor (statins) in type 2 diabetes, the main aim of our study was to evaluate the effects of "therapeutic" doses of atorvastatin on gonadal and adrenal hormones in 24 type 2 diabetic patients (16 males and 8 postmenopausal females), with mild to moderate hypercholesterolemia (LDL-cholesterol = 150.1 +/- 32.0 and 189.9 +/- 32.9 mg/dl, respectively) studied before and after a 3 months treatment with atorvastatin (20 mg/day). In all patients, lipids and serum cortisol, dehydroepiandrosterone sulphate (DHEA-S), androstendione and sex hormone binding globulin (SHBG) were measured, with the addition, only in males, of testosterone and free testosterone index. After atorvastatin treatment a significant decrease in total and LDL cholesterol was observed (p < 0.05), while HDL-cholesterol did not significantly change ( p = N.S.), as no significant difference was found between steroid hormones measured before and after atorvastatin either in male and females. In conclusion, our data suggest that, in type 2 diabetic patients, the use of atorvastatin has no clinically important effects on either gonadal or adrenal steroid hormones.

    Background: Traction has been suggested to be an effective treatment for symptoms of neck disorder in patients with no contraindications. However, according to previous researches, the effectiveness of traction is controversial, particularly compared to other conservative treatments. This trial was conducted to evaluate the effect of sustained traction, using an over-the-door home cervical traction unit in combination with routine physical therapy on reducing cervical osteoarthrosis symptoms including neck pain, medication use and disability level compared to routine physical therapy alone. Methods: In this double- blinded pilot study with a pre-post test design and a control group, 20 women with mild to moderate osteoarthrosis were systematically assigned to the over-the-door home cervical traction (mean±SD age: 50.5±4.45yrs) or control groups (mean±SD age: 55.6±7.34yrs). Pain, level of disability, and drug consumption were evaluated before and after 10 sessions of intervention. Data were analyzed using parametric or non-parametric statistic including the paired-sample t-test, independent sample t-test, and Wilcoxon and Mann-Whitney u test for intra and inter groups comparison based on the Kolmogorov-Smirnov test results. Results: Patients in both groups showed a significant decrease in pain intensity and disability level (p<0.05). Despite the greater improvement in pain levels and disability in the experimental group compared to the controls, the differences were not significant (p>0.05). No significant differences were found in terms of drugs consumption within and between the groups at the end of the treatment (p>0.05). Conclusion: The results revealed that applying sustained traction using an over-the-door home cervical traction unit was not significantly superior to the routine physical therapy and ergonomic training to manage symptoms including neck pain and disability in a small group of mild to moderate cervical osteoarthrosis patients.

    A 26-year-old female pianist suffered from an intracerebral hematoma caused by an arteriovenous malformation of the left occipital parasplenial region, which was operated on seven months after the onset. Incomplete right hemianopsia, mild pure alexia, and partially disturbed naming of visual objects persisted several months after the removal of the malformation. Evaluation of musical ability one and three months after surgery showed that her auditory recognition of music was intact. She could sing and play melodies already learned and could dictate well the notes after hearing tones. However, she had difficulty in reading music, especially the pitch of notes, even for simple sequences of 4 notes. In contrast, her rhythm reading was fairly good. Her visual recognition of other symbolic figures like road signs was also markedly impaired. These results suggest that her visual recognition of written music as well as of other symbolic figures underwent a preliminary verbal decoding in the left hemisphere and that pitch reading was more dependent on verbal processing than rhythm reading.

    Previous studies have suggested that amnestic mild cognitive impairment (aMCI) is associated with changes in cortical morphological features, such as cortical thickness, sulcal depth, surface area, gray matter volume, metric distortion, and mean curvature. These features have been proven to have specific neuropathological and genetic underpinnings. However, most studies primarily focused on mass-univariate methods, and cortical features were generally explored in isolation. Here, we used a multivariate method to characterize the complex and subtle structural changing pattern of cortical anatomy in 24 aMCI human participants and 26 normal human controls. Six cortical features were extracted for each participant, and the spatial patterns of brain abnormities in aMCI were identified by high classification weights using a support vector machine method. The classification accuracy in discriminating the two groups was 76% in the left hemisphere and 80% in the right hemisphere when all six cortical features were used. Regions showing high weights were subtle, spatially complex, and predominately located in the left medial temporal lobe and the supramarginal and right inferior parietal lobes. In addition, we also found that the six morphological features had different contributions in discriminating the two groups even for the same region. Our results indicated that the neuroanatomical patterns that discriminated individuals with aMCI from controls were truly multidimensional and had different effects on the morphological features. Furthermore, the regions identified by our method could potentially be useful for clinical diagnosis. PMID:25100588

    Introduction: Cerebro-vascular diseases (CVD) are the leading cause of symptomatic epilepsies. This study aims to investigate: a) Frequency of epilepsy in patients with CVD; b) Correlation of epilepsy with the type of CVD (ischemic and hemorrhage) and with age. Methodology: It is analyzed medical documentation of 816 hospitalized patients with CVD in the clinic of Neurology in University Clinical Center (UCC) during the period January - December 2010. The study included data on patients presenting with epileptic seizures after CVD, and those with previously diagnosed epilepsy, are not included in the study. The diagnosis of CVD, are established in clinical neurological examination and the brain imaging (computer tomography and magnetic resonance imaging). The diagnosis of epilepsy is established by the criteria of ILAE (International League against Epilepsy) 1983, and epileptic seizures are classified according to the ILAE classification, of 1981. Results: Out of 816 patients with CVD, 692 were with ischemic stroke and 124 with hemorrhage. From 816 patients, epileptic seizures had 81 (10%), of which 9 patients had been diagnosed with epilepsy earlier and they are not included in the study. From 72 (99%) patients with seizures after CVD 25 (33%) have been with ischemia, whereas 47 (67%) with hemorrhage. Conclusion: CVD present fairly frequent cause of symptomatic epilepsies among patients treated in the clinic of Neurology at UCC (about 10%). The biggest number of patients with epilepsy after CVD was with intracerebral hemorrhage. PMID:25685086

    Introduction: The prevalence of symptomatic knee osteoarthritis (OA) among Asians ≥65 years is estimated to double by 2040. This study was designed to evaluate the safety and efficacy of a single, 6-mL intra-articular injection of hylan G-F 20 in Indian patients with knee OA at 26 weeks through to 52 weeks. Methods: This study was an open-label, multicentre, phase 4 clinical trial. Enrolled patients (N=394) were ≥30 years old with Kellgren-Lawrence grade 1–3 OA; all patients received hylan G-F 20. WOMAC, SF-12, PTGA, and COGA scores, and OA medication use were evaluated at weeks 1, 4, 12, 26, 39, and 52 (initial treatment phase). At 26, 39, or 52 weeks, eligible patients could participate in a repeat treatment phase. McNemar-Bowkers, paired t-tests and ANOVA analyses were performed (alpha=0.05). Results: At 26 weeks, statistically significant changes from baseline were observed in all efficacy parameters, including the primary efficacy endpoint of WOMAC A1 (p<0.0001). Improvements continued for 52 weeks. No significant changes occurred in concomitant medication use. Eleven patients (2.8%) were re-injected at week 26 or 52. After repeat injection, statistically significant decreases were observed in WOMAC A1, WOMAC C and PTGA scores (p≤0.028). Twenty-three (5.8%) patients reported 26 local target knee AEs. Conclusion: Among Indian patients within this study, a 6-mL hylan G-F 20 injection was well tolerated and effective in treating symptomatic knee OA with significant long-term (1 year) improvement of outcomes. When needed, repeat treatment was safe and efficacious for 4 weeks. Trial Registration: Clinical Trial Registry of India (CTRI/2010/091/000052) www.ctri.nic.in/Clinicaltrials/login.php.

    Context Carpal bossing is an osseous formation at the dorsal portion of the quadrangular joint, which rarely becomes symptomatic. However, in some patients it causes pain, restricted mobility and can lead to complications like tendon rupture, inflammatory and degenerative joint disease. Aim In this article, we present our experiences with this rare disorder in order to improve diagnostic and therapeutic proceedings. Settings Design This is a multicenter and interdisciplinary observation made by orthopaedic surgeons and radiologists in the years 2010 to 2015. Retrospective observational study. The follow up period was 2 years. Materials and Methods In the observed time period, eight patients were diagnosed with symptomatic carpal bossing. Symptoms were pain at palmar flexion and limited mobility of the wrist in combination with a palpable protuberance over the quadrangular joint. All patients underwent X-ray, CT and MRI examinations. A conservative treatment strategy was initiated for 6 weeks in all patients, followed by a wedge resection when symptoms were persisting and disabling. Results After the conservative treatment schedule, five patients were asymptomatic. Three patients had persisting pain and were thus recommended for surgery. In the postoperative course, two patients were asymptomatic. One patient developed a type 1 complex regional pain syndrome (CRPS) in the first postoperative year, which was successfully treated with pain-adapted physiotherapy, pharmacotherapy with analgesics and calcitonin, and a triple CT-guided thoracic sympathetic nerve blockade. Conclusion Carpal bossing is a mostly asymptomatic entity, which in our experience gets symptomatic due to direct trauma or repetitive stress, especially in competitive racket sports players. It can be diagnosed by thorough clinical examination and multimodal diagnostic imaging. Conservative treatment comprises an excellent prognosis, however surgery, either wedge resection or arthrodesis, must be

    Identification of predictors of cardiovascular risk can help in the prevention of pathologic episodes and the management of patients at all stages of illness. Here, we investigated the relationships between serum levels of Hsp60 and dyslipidemia in patients with periodontitis by performing a cross-sectional study of 22 patients with mild periodontitis without any prior treatment for it (i.e., drug naïve) and 22 healthy controls, matched for age and body mass index (BMI). All subjects were evaluated for periodontal status, gingival inflammation, and oral hygiene. Levels of circulating Hsp60, C-reactive protein (CRP), and plasma lipids were measured, and small, dense low-density lipoproteins (LDL) were indirectly assessed by determining the triglycerides/high-density lipoproteins (HDL) cholesterol ratio. We also assessed by immunohistochemistry Hsp60 levels in oral mucosa of patients and controls. No difference was found in CRP levels or plasma lipids between the two groups, but subjects with periodontitis showed, in comparison to controls, higher levels of small, dense LDL (p  = 0.0355) and circulating Hsp60 concentrations (p < 0.0001). However, levels of mucosal Hsp60 did not change significantly between groups. Correlation analysis revealed that circulating Hsp60 inversely correlated with HDL-cholesterol (r  = -0.589, p  = 0.0039), and positively with triglycerides (r  = +0.877, p < 0.0001), and small, dense LDL (r  = +0.925, p < 0.0001). Serum Hsp60 significantly correlated with the degree of periodontal disease (r  = +0.403, p  = 0.0434). In brief, untreated patients with mild periodontitis had increased small, dense LDL and serum Hsp60 concentrations, in comparison to age- and BMI-matched controls and both parameters showed a strong positive correlation. Our data indicate that atherogenic dyslipidemia and elevated circulating Hsp60 tend to be linked and associated to periodontal pathology. Thus, the road is open to

    Alzheimer’s disease (AD), the most common form of dementia, shares many aspects of abnormal brain aging. We present a novel magnetic resonance imaging (MRI)-based biomarker that predicts the individual progression of mild cognitive impairment (MCI) to AD on the basis of pathological brain aging patterns. By employing kernel regression methods, the expression of normal brain-aging patterns forms the basis to estimate the brain age of a given new subject. If the estimated age is higher than the chronological age, a positive brain age gap estimation (BrainAGE) score indicates accelerated atrophy and is considered a risk factor for conversion to AD. Here, the BrainAGE framework was applied to predict the individual brain ages of 195 subjects with MCI at baseline, of which a total of 133 developed AD during 36 months of follow-up (corresponding to a pre-test probability of 68%). The ability of the BrainAGE framework to correctly identify MCI-converters was compared with the performance of commonly used cognitive scales, hippocampus volume, and state-of-the-art biomarkers derived from cerebrospinal fluid (CSF). With accuracy rates of up to 81%, BrainAGE outperformed all cognitive scales and CSF biomarkers in predicting conversion of MCI to AD within 3 years of follow-up. Each additional year in the BrainAGE score was associated with a 10% greater risk of developing AD (hazard rate: 1.10 [CI: 1.07–1.13]). Furthermore, the post-test probability was increased to 90% when using baseline BrainAGE scores to predict conversion to AD. The presented framework allows an accurate prediction even with multicenter data. Its fast and fully automated nature facilitates the integration into the clinical workflow. It can be exploited as a tool for screening as well as for monitoring treatment options. PMID:23826273

    Few therapeutic options are available nowadays to improve the prognosis of patients with Alzheimer's disease (AD). There are rather several evidences in literature that controlling vascular risk factors may be an effective intervention for modifying the course of this disease. The aim of our study was to investigate the role of CRF in 50 patients with MCI according to Petersens's criteria, and to evaluate their influence on cognitive and behavioral features of the disease and on the development of dementia. Statistical analysis of the data showed that the 60% of the patients with MCI and CRF developed dementia, while 40% maintained the same cognitive conditions at the end of the study. Only 32% of the subjects without cardiovascular comorbidities developed dementia. The results of the study suggest that CRF play a key role in cognitive decline of patients with MCI. Patients with MCI and CRF showed not only worse cognitive performances, but also behavioral disorders, depression and functional disability. Patients with CRF had higher conversion rate to AD than the other group, with a mean disease-free period 3 months shorter than the control group. PMID:21632127

    We identified mosaic 1p36 deletions in two patients with developmental delay, distinctive features, and obesity, who can walk alone and communicate with others. Thus, their neurological defects are milder than those in typical patients with 1p36 deletion syndrome because most patients with 1p36 deletion cannot acquire expressive language. Chromosomal microarray testing revealed 3.0 and 4.5 Mb aberrations in the subtelomeric region of the short arm of chromosome 1. Mean signal ratios of the identified aberrations were -0.4 and -0.5, indicating mosaicism, which was confirmed by fluorescence in situ hybridization analysis with a mosaic ratio of 70% and 77%, respectively. Previous studies demonstrated that deletion of the distal 2-3 Mb region would be responsible for hyperphagia and obesity seen in patients. On the other hand, the severity of the neurological defect often correlates with the size of the terminal deletion of 1p36, and patients with larger deletions of 1p36 would usually show severely impaired developmental milestones and be immobile and aphasic. In such cases, hyperphagia and obesity could be clinically masked. In this study, two patients with mosaic deletions of 1p36 showed obesity as a consequence of hyperphagia. This study suggests that patients with 1p36 deletion would be at risk for hyperphagia and obesity when they have both risk factors, that is, (1) deletions including the 2-3 Mb critical region and (2) milder phenotypes that allow them to reach food on their own and to overeat.

    Wilson's disease (WD) is an autosomal recessive metabolic disorder characterized by cognitive, psychiatric and motor signs and symptoms that are associated with structural and pathological brain abnormalities, in addition to liver changes. However, functional brain connectivity pattern of WD patients remains largely unknown. In the present study, we investigated functional brain connectivity pattern of WD patients using resting state functional magnetic resonance imaging. Particularly, we studied default mode network (DMN) using posterior cingulate cortex (PCC) based seed functional connectivity analysis and graph theoretic functional brain network analysis tools, and investigated the relationship between the DMN's functional connectivity pattern of WD patients and their attention functions examined using the attention network test (ANT). Our results demonstrated that WD patients had altered DMN's functional connectivity and lower local and global network efficiency compared with normal controls (NCs). In addition, the functional connectivity between left inferior temporal cortex and right lateral parietal cortex was correlated with altering function, one of the attention functions, across WD and NC subjects. These findings indicated that the DMN's functional connectivity was altered in WD patients, which might be correlated with their attention dysfunction.

    Symptomatic os trigonum is a rare condition, well described in adults, that causes chronic ankle pain. To date there are no reported cases of successfully managed symptomatic os trigonum in the children population. We retrospectively reviewed four paediatric patients (11-17 years of age) successfully operated for a symptomatic os trigonum using an open excision through a posteromedial approach. One case was bilateral. Postoperative pain relief was obtained in all cases. All of the patients were able to return to unrestricted physical activities after three months. The average follow-up was 12 months. Symptomatic os trigonum may be held responsible for chronic ankle pain in children and adolescents as well as in adults. The surgical treatment is effective in children.

    A long-term follow-up was performed on 22 patients treated for a posterior glenoid osteophyte and symptomatic posterior shoulder pain during either the late cocking, acceleration, or follow-through phases of throwing. Arthroscopic evaluation of these patients revealed undersurface tearing of the rotator cuff in all but one. Fifteen patients also had tearing of the posterior labrum. Anterior labral fraying was noted in four patients. Treatment consisted of debridement of the rotator cuff and labral tears. The posterior glenoid osteophyte was removed arthroscopically in 11 patients. Eighteen of 22 throwers treated were available for long-term follow-up at a mean of 6.3 years (range, 1 to 12). Only 10 of 18 (55%) throwers evaluated had returned to their premorbid level of throwing. All 10 were asymptomatic and had maintained a high level of performance for a mean of 3.6 years (range, 1 to 8). At the time of latest follow-up, five players were still participating at the major league level and five had retired. One patient had recurrence of the exostosis 8 years after surgery. Among our patients a trend existed toward a poorer result and failure of return to activity with a posterior osteophyte greater than 100 mm2. A posterior glenoid exostosis, when identified in the symptomatic shoulder of the throwing athlete, can be considered a definite marker of internal impingement.

    Intellectual disability affects approximately 2% of the population, with affected males outnumbering affected female, partly due to disturbances involving X-linked genes. To date >90 genes associated with X-linked intellectual disability have been identified and, among these, IL1RAPL1 (interleukin 1 receptor accessory protein-like 1), was first described and mapped to Xp21.3-22.1 in 1999. Intragenic deletions of IL1RAPL1, only rarely identified, have mostly been associated with nonspecific intellectual disability (IDX) and autism spectrum disorder. Array-CGH analysis performed in our patient with intellectual disability, mild dysmorphic signs and changes in behavior identified a 285 Kb deletion in chromosome Xp21.3-21.2, with breakpoints lying in IL1RAPL1 gene intron 2 and intron 3. This is the first patient reported in literature with deletion of only exon 3 of IL1RAPL1 gene. Our patient also exhibits bilateral progressive neurosensorial deafness, which has not been previously associated with IL1RAPL1 mutations. PMID:23613341

    Amnesic mild cognitive impairment (aMCI) is a heterogeneous syndrome that could be subdivided into distinct neuropsychological variants. To investigate relationships between the neuropsychological profile of memory impairment at baseline and the neuroimaging pattern of grey matter (GM) loss over 18 months, we performed a prospective volumetric brain study on 31 aMCI patients and 29 matched controls. All subjects were tested at baseline using a standardized neuropsychological battery, which included the Free and Cued Selective Recall Reminding Test (FCSRT) for the assessment of verbal declarative memory. Over 18 months, patients with impaired free recall but normal total recall (high index of cueing) on the FCSRT developed subcortical and frontal GM loss, while patients with impaired free and total recall (low index of cueing) developed GM atrophy within the left anterior and lateral temporal lobe. In summary, cued recall deficits are associated with a progression of atrophy that closely parallels the spatiotemporal distribution of neurofibrillary degeneration in early Alzheimer's disease (AD), indicating possible AD pathological changes.

    Amnesic mild cognitive impairment (aMCI) is a heterogeneous syndrome that could be subdivided into distinct neuropsychological variants. To investigate relationships between the neuropsychological profile of memory impairment at baseline and the neuroimaging pattern of grey matter (GM) loss over 18 months, we performed a prospective volumetric brain study on 31 aMCI patients and 29 matched controls. All subjects were tested at baseline using a standardized neuropsychological battery, which included the Free and Cued Selective Recall Reminding Test (FCSRT) for the assessment of verbal declarative memory. Over 18 months, patients with impaired free recall but normal total recall (high index of cueing) on the FCSRT developed subcortical and frontal GM loss, while patients with impaired free and total recall (low index of cueing) developed GM atrophy within the left anterior and lateral temporal lobe. In summary, cued recall deficits are associated with a progression of atrophy that closely parallels the spatiotemporal distribution of neurofibrillary degeneration in early Alzheimer's disease (AD), indicating possible AD pathological changes.

    [Purpose] The trunk muscles frequently become weak after stroke, thus impacting overall activities of daily living. However, activities of daily living items closely related with trunk strength remain unclear. This study aimed to clarify the influence of trunk muscle weakness on activities of daily living items. [Subjects] The subjects were 24 stroke patients who fulfilled the following inclusion criteria: first stroke and the absence of severe paralysis, marked cognitive function deterioration, unilateral spatial neglect or apathy. [Methods] According to abdominal strength, the 24 patients were divided into a nonweakness group and a weakness group. For the assessment, we used the stroke impairment assessment set, the Berg balance scale, a simple test for evaluating hand function, grip strength, and functional independence measure scale scores and the results were compared between the groups. [Results] The Berg balance scale score and scores for dressing, toilet use, transfer to bed, and walk items of the functional independence measure were significantly lower in the weakness group than in the nonweakness group. [Conclusion] Our results suggest that weakness of the abdominal muscles adversely impacts the balance of patients with mild stroke as well as their ability to dress, use a toilet, transfer, and walk. Trunk training, including abdominal muscle exercises, can effectively improve the performance of these activities of daily living items.

    Cell-adhesion molecules play critical roles in brain development, as well as maintaining synaptic structure, function, and plasticity. Here we have found the disruption of two genes encoding putative cell-adhesion molecules, CDH15 (cadherin superfamily) and KIRREL3 (immunoglobulin superfamily), by a chromosomal translocation t(11;16) in a female patient with intellectual disability (ID). We screened coding regions of these two genes in a cohort of patients with ID and controls and identified four nonsynonymous CDH15 variants and three nonsynonymous KIRREL3 variants that appear rare and unique to ID. These variations altered highly conserved residues and were absent in more than 600 unrelated patients with ID and 800 control individuals. Furthermore, in vivo expression studies showed that three of the CDH15 variations adversely altered its ability to mediate cell-cell adhesion. We also show that in neuronal cells, human KIRREL3 colocalizes and interacts with the synaptic scaffolding protein, CASK, recently implicated in X-linked brain malformation and ID. Taken together, our data suggest that alterations in CDH15 and KIRREL3, either alone or in combination with other factors, could play a role in phenotypic expression of ID in some patients.

    The author observed a new accessory bone of the foot in the distal portion of navicular, which articulated with the medial cuneiform and the intermediate cuneiform, and named it os infranaviculare. A degenerative change was observed between the accessory bone and the navicular; this caused midfoot pain to the patient during weight-bearing. Thus, the patient was treated by excision of the accessory bone. The symptom was relieved at one-year postoperative. PMID:23730481

    OBJECTIVE: To determine the usefulness of measuring the cardiac natriuretic peptides, atrial natriuretic factor, N-terminal pro-atrial natriuretic factor, and brain natriuretic peptide, as screening tests for identifying patients with mild left ventricular impairment. DESIGN: Cross-sectional evaluation of the diagnostic accuracy of the cardiac natriuretic peptides. SETTING: Cardiac catheterisation unit, Norwegian central hospital. PATIENTS: A consecutive series of 254 patients undergoing diagnostic left-sided cardiac catheterisation. One hundred and twenty eight of these patients had a history of previous myocardial infarction. MAIN OUTCOME MEASURES: The presence of normal and impaired left ventricular function, as evaluated by logistic regression analysis and estimation of the area under the receiver operating characteristic (ROC) curve (an index of overall diagnostic accuracy). Ventricular function was assessed by the measurement of left ventricular end diastolic pressure and angiographically determined left ventricular ejection fraction. RESULTS: Logistic regression analysis showed that plasma brain natriuretic peptide was the best predictor of increased left ventricular end diastolic pressure (> or = 15 mm Hg) (P < 0.001), decreased left ventricular ejection fraction (< or = 45%) (P < 0.001), and the combination of left ventricular ejection fraction < or = 45% and left ventricular end diastolic pressure > or = 15 mm Hg (P < 0.001). The areas under the ROC function for the detection of left ventricular dysfunction were 0.789 for brain natriuretic peptide, 0.665 for atrial natriuretic factor, and 0.610 for N-terminal pro-atrial natriuretic factor. CONCLUSIONS: Plasma brain natriuretic peptide seemed to be a better indicator of left ventricular function than plasma atrial natriuretic factor or N-terminal pro-atrial natriuretic factor. However, the overall diagnostic accuracy of circulating atrial natriuretic factor, N-terminal pro-atrial natriuretic factor, and

    Evidence suggests that the tumor necrosis factor receptor (TNFR)-signaling pathway contributes to the pathogenesis of Alzheimer’s disease (AD). TNF-α converting enzyme (TACE/ADAM-17) can cleave both pro-TNF-α and TNF receptors. Recently, we have shown that TACE activity in the cerebrospinal fluid (CSF) of subjects with mild cognitive impairment (MCI) and AD patients is significantly higher than that of cognitively healthy controls (HC). To date, it is not clear whether TACE activity could be detected in the human plasma and whether TACE activity in MCI and AD patients is different from that in HC. We analyze TACE expression and activity in a large clinical sample of 64 patients with AD, 88 subjects with MCI, and 50 age-matched HC recruited from two distinct academic centers. Plasma TACE protein levels did not differ significantly in the three study groups (AD, MCI, and HC). However, plasma TACE activity in subjects with MCI and AD patients was significantly higher than that in HC. Moreover, in MCI and AD groups, we found a significant correlation between plasma TACE activity and CSF t-tau and Aβ42 levels and CSF Aβ42/tau ratios. In AD patients, the levels of plasma TACE activity correlated significantly and negatively with cognition. These findings further support the role of the TNF-α receptor complex in AD-related neuroinflammation and propose TACE plasma activity as a promising hypothesis-driven biomarker candidate for detection, diagnosis, and prognosis of prodromal and clinical AD.

    Gait disturbance results in an increase in the risk of falls in patients with Alzheimer's disease (AD). The falls are events that might be related to an increase in the number of fractures, loss of mobility, being bedridden, early institutionalization, and increased use of medication. Therefore, the reduction in the number of falls is important for the maintenance of the functional independence of the patients as well as for the prevention of sequelae resulting from those events. Alterations in the gait occur very frequently in AD, and the gait disturbance occurs relatively early in the course of the disease. This study has important implications for public health and clinical practice. This study and previous studies have reported that abnormal gait predicts greater risk of falls, dementia, institutionalization, and death. The high prevalence and incidence of abnormal gait and its association with multiple adverse outcomes in older adults require urgent attention. Our results allow us to identify the risk factors.

    A 26-year-old man with a history of Crohn's disease was struck in the abdomen by an opponent's shoulder while playing basketball. He presented to the emergency department 3 hours later with the complaint of abdominal pain and was admitted to the hospital for observation. Nine hours after presentation a computed tomography scan showed he had pneumoperitoneum and then underwent laparotomy. A perforated segment of sigmoid colon with severe inflammatory disease was found and resected. The rest of his small and large bowels were otherwise unremarkable. His localized but severe inflammatory bowel disease predisposed him to bowel perforation with minimal trauma. This is the first report of a patient with inflammatory bowel disease and traumatic colon perforation; it is also the first report of a patient with a bowel perforation with minimal traumatic force.

    Effectiveness and tolerability of two piracetam-containing drugs were compared in the frame of an open, multicentre, Phase-IV, prospective study with group and self control carried out in 9 Hungarian centres in 1998. Patients with cognitive decline from Alzheimer's disease and/or cerebrovascular origin have received the drug, in the first 4 weeks in 4800, later 2400 mg daily doses. One hundred four patients finished the study. No relevant difference with statistically significant degree was registered between the two groups. Based on this fact in this study data of the 104 patients were examined together. Authors examined two problems. The first: on which cognitive function is more effective the drug. Five factors of the modified Mini-Mental State Examination were separated and compared. Nearly all of them significantly increased especially the factors of memory, and concentration-psychomotor speed. The second examined field: are there certain subgroups with prognostic value about the effectiveness of piracetam treatment. Neither the duration of the illness, nor etiologic diagnosis, severity of cognitive decline, or former treatment with piracetam did influence significantly the efficacy. In case of depressive symptoms such connection was established: the more pronounced the severity of these symptoms the higher improvement can be expected in cognitive functions. This was also stressed by the logistic regression analysis. Authors described an original evaluation method of the trail-making test, which could widen the application of this popular test in psychopharmacologic studies. Final conclusions: the cognitive enhancer effect of piracetam appeared in a few weeks. This treatment could be effective even in Alzheimer's disease, in case of more pronounced cognitive decline, longer duration of the illness, and in case of former piracetam treatment as well. The degree of cognitive improvement was most pronounced in patients with comorbid depressive symptoms.

    Background. Because of the increased risk of surgery, thyroid nodules causing compression signs and/or hyperthyroidism are concerning during pregnancy. Patients and Methods. Six patients with nontoxic cystic, four with nontoxic solid, and three with overt hyperthyroidism caused by toxic nodules were treated with percutaneous ethanol injection therapy (PEI). An average of 0.68 mL ethanol per 1 mL nodule volume was administered. Mean number of PEI treatments for patients was 2.9. Success was defined as the shrinkage of the nodule by more than 50% of the pretreatment volume (V0) and the normalization of TSH and FT4 levels. The average V0 was 15.3 mL. Short-term success was measured prior to labor, whereas long-term success was determined during the final follow-up (an average of 6.8 years). Results. The pressure symptoms decreased in all but one patient after PEI and did not worsen until delivery. The PEI was successful in 11 (85%) and 7 (54%) patients at short-term and long-term follow-up, respectively. Three patients underwent repeat PEI which was successful in 2 patients. Conclusions. PEI is a safe tool and seems to have good short-term results in treating selected symptomatic pregnant patients. Long-term success may require repeat PEI. PMID:26697066

    Severe hallux valgus deformity with proximal instability creates pain and deformity in the forefoot. First tarsometatarsal joint arthrodesis is performed to reduce the intermetatarsal angle and stabilize the joint. Dorsomedial locking plate fixation with adjunctive lag screw fixation is used because of its superior construct strength and healing rate. Despite this, questions remain regarding whether this hardware is more prominent and more likely to need removal. The purpose of the present study was to determine the incidence of symptomatic hardware at the first tarsometatarsal joint and to determine the incidence of hardware removal resulting from prominence and/or discomfort. A review of 165 medical records of consecutive patients who had undergone first tarsometatarsal joint arthrodesis with plate fixation was conducted. The outcome of interest was the incidence of symptomatic hardware removal in patients with clinical union. The mean age was 55 (range 18.4 to 78.8) years. The mean follow-up duration was 65.9 ± 34.0 (range 7.0 to 369.0) weeks. In our cohort, 25 patients (15.2%) had undergone hardware removed because of pain and irritation. Of these patients, 18 (72.0%) had a locking plate and lag screw removed, and 7 (28.0%) had crossing lag screws removed. The fixation of a first tarsometatarsal joint fusion poses a difficult situation owing to minimal soft tissue coverage and the inherent need for robust fixation to promote fusion. Hardware can become prominent postoperatively and can become painful and/or induce cutaneous compromise. The results of the present observational investigation imply that surgeons can reasonably inform patients that the incidence of symptomatic hardware removal after first tarsometatarsal arthrodesis is approximately 15% within a median duration of 9.0 months after surgery.

  20. The SNAP trial: a double blind multi-center randomized controlled trial of a silicon nitride versus a PEEK cage in transforaminal lumbar interbody fusion in patients with symptomatic degenerative lumbar disc disorders: study protocol

    PubMed Central

    2014-01-01

    Background Polyetheretherketone (PEEK) cages have been widely used in the treatment of lumbar degenerative disc disorders, and show good clinical results. Still, complications such as subsidence and migration of the cage are frequently seen. A lack of osteointegration and fibrous tissues surrounding PEEK cages are held responsible. Ceramic implants made of silicon nitride show better biocompatible and osteoconductive qualities, and therefore are expected to lower complication rates and allow for better fusion. Purpose of this study is to show that fusion with the silicon nitride cage produces non-inferior results in outcome of the Roland Morris Disability Questionnaire at all follow-up time points as compared to the same procedure with PEEK cages. Methods/Design This study is designed as a double blind multi-center randomized controlled trial with repeated measures analysis. 100 patients (18–75 years) presenting with symptomatic lumbar degenerative disorders unresponsive to at least 6 months of conservative treatment are included. Patients will be randomly assigned to a PEEK cage or a silicon nitride cage, and will undergo a transforaminal lumbar interbody fusion with pedicle screw fixation. Primary outcome measure is the functional improvement measured by the Roland Morris Disability Questionnaire. Secondary outcome parameters are the VAS leg, VAS back, SF-36, Likert scale, neurological outcome and radiographic assessment of fusion. After 1 year the fusion rate will be measured by radiograms and CT. Follow-up will be continued for 2 years. Patients and clinical observers who will perform the follow-up visits will be blinded for type of cage used during follow-up. Analyses of radiograms and CT will be performed independently by two experienced radiologists. Discussion In this study a PEEK cage will be compared with a silicon nitride cage in the treatment of symptomatic degenerative lumbar disc disorders. To our knowledge, this is the first randomized controlled

    Background Central cord syndrome (CCS) is considered the most common incomplete spinal cord injury (SCI). Independent ambulation was achieved in 87-97% in young patients with CCS but no gait analysis studies have been reported before in such pathology. The aim of this study was to analyze the gait characteristics of subjects with CCS and to compare the findings with a healthy age, sex and anthropomorphically matched control group (CG), walking both at a self-selected speed and at the same speed. Methods Twelve CCS patients and a CG of twenty subjects were analyzed. Kinematic data were obtained using a three-dimensional motion analysis system with two scanner units. The CG were asked to walk at two different speeds, at a self-selected speed and at a slower one, similar to the mean gait speed previously registered in the CCS patient group. Temporal, spatial variables and kinematic variables (maximum and minimum lower limb joint angles throughout the gait cycle in each plane, along with the gait cycle instants of occurrence and the joint range of motion - ROM) were compared between the two groups walking at similar speeds. Results The kinematic parameters were compared when both groups walked at a similar speed, given that there was a significant difference in the self-selected speeds (p < 0.05). Hip abduction and knee flexion at initial contact, as well as minimal knee flexion at stance, were larger in the CCS group (p < 0.05). However, the range of knee and ankle motion in the sagittal plane was greater in the CG group (p < 0.05). The maximal ankle plantar-flexion values in stance phase and at toe off were larger in the CG (p < 0.05). Conclusions The gait pattern of CCS patients showed a decrease of knee and ankle sagittal ROM during level walking and an increase in hip abduction to increase base of support. The findings of this study help to improve the understanding how CCS affects gait changes in the lower limbs. PMID:21288347

    The population pharmacokinetics of bapineuzumab, a humanized monoclonal IgG1 antibody that was generated from a murine monoclonal antibody and binds specifically to amino acids 1 to 5 of the free N-terminus of human amyloid-beta peptide, were characterized in patients with mild-to-moderate alzheimer's disease in two Phase 3 studies (ELN115727-301 and ELN115727-302). A total of 8,040 serum concentration measurements were analyzed from 1,458 patients who received 6 doses of bapineuzumab intravenously once every 13 weeks. A confirmatory analysis was conducted using a prespecified two-compartment model with first-order elimination. After the primary covariate effect assessment, a reduced model was obtained. Based on the reduced model, the typical population values for clearance (CL) and volume (Vc ) from the central compartment in a Caucasian subject with a standardized body weight of 70 kg were 0.17 L/day and 3.13 L, respectively. Bapineuzumab CL and Vc increased with body weight. Furthermore, CL was 15% higher in non-Caucasian subjects; however, this was not considered clinically relevant. None of the other evaluated covariates had a meaningful impact on CL. The median terminal elimination half-life was estimated to be approximately 29 days. Sensitivity analyses and bootstrapping results supported model stability. PMID:25187399

    Disruptions of the functional brain network and cerebral blood flow (CBF) have been revealed in patients with mild cognitive impairment (MCI). However, the neurophysiological mechanism of hypoperfusion as well as the reorganization of the intrinsic whole brain network due to the neuropathology of MCI are still unclear. In this study, we aimed to investigate the changes of CBF and the whole brain network organization in MCI by using a multimodal MRI approach. Resting state ASL MRI and BOLD MRI were used to evaluate disruptions of CBF and underlying functional connectivity in 27 patients with MCI and 35 cognitive normal controls (NC). The eigenvector centrality mapping (ECM) was used to assess the whole brain network reorganization in MCI, and a seed-based ECM approach was proposed to reveal the contributions of the whole brain network on the ECM alterations. Significantly decreased perfusion in the posterior parietal cortex as well as its connectivity within the default mode network and occipital cortex were found in the MCI group compared to the NC group. The ECM analysis revealed decreased EC in the middle cingulate cortex, parahippocampal gyrus, medial frontal gyrus, and increased EC in the right calcarine sulcus, superior temporal gyrus, and supplementary motor area in the MCI group. The results of this study indicate that there are deficits in cerebral blood flow and functional connectivity in the default mode network, and that sensory-processing networks might play a compensatory role to make up for the decreased connections in MCI.

    Memory tests able to differentiate encoding and retrieval processes from the memoranda storing ones should be used to differentiate patients in a very early phase of AD. In fact, individuals with mild cognitive impairment (MCI) can be characterized by two different memory profiles: a pure amnestic one (with poor learning and retrieval and poor improvement when encoding is assisted and retrieval is facilitated) and a dysexecutive one (with inefficient encoding and/or poor retrieval strategies and improvement with assisted encoding and retrieval). The amnestic profile characterizes subjects affected by medio-temporal atrophy typical of AD. In this study, a Grober-Buschke memory procedure was used to evaluate normal controls and MCI patients with different cognitive profiles: pure amnestic (aMCIsd), amnestic plus other cognitive impairments (aMCImd) and non-amnestic (naMCI). An index of sensitivity of cueing (ISC) measured the advantage passing from free to cued recall. Results showed that both strategic and consolidation abilities were impaired in the aMCIsd and aMCImd groups and were preserved in the naMCI group. aMCImd, however, compensated the memory deficit with assisted encoding and retrieval, but aMCIsd performed very poorly. When MCI subjects were defined according to the ISC value, subjects with poor ISC were primarily in the aMCIsd group and, to a lesser extent, in the aMCImd group and the naMCI group. Finally, patients with a poor ISC showed cerebral atrophy documented in the precocious phase of AD and the retrosplenial cerebral areas seemed to be the most useful areas for identifying patients in the early phase of AD.

    Clear standards are lacking in the imaging modalities of the deficit in mild traumatic brain injury (MTBI) patients. The purpose of this study is to compare the image quality by signal distribution between 1.5 Tesla and 3 Tesla MRI in turbo spin echo (TSE) and gradient echo (GRE) images in normal hospital settings and to find preferences for which field to use in MTBI patients. We studied 40 MTBI patients with TSE and GRE; 20 patients were imaged at 1.5 T and 20 at 3 T. The imaging parameters were optimized separately for the two scanners. Histograms of the signal distribution in 22 ROIs were fitted to a 1-peak Gaussian model and the resulting peak positions were scaled in respect to the peak positions of genu of the corpus callosum and the caudate nuclei. Correlation of the contrast of the ROIs in reference to genu of the corpus callosum between both the two scanners and the two imaging sequences was good. Image contrast was similar at both in the TSE images; in the GRE images contrast improved from 1.5 T to 3 T. However, based on peak positions and widths, a slight drawback in the separability between the ROIs was observed when 1.5 T MRI was replaced by 3 T. No clear improvement in tissue contrast or separability of 3 T was found compared to 1.5 T. Imaging of MTBI with 3 T should therefore be based on other advantages of high-field imaging, such as improved SNR and spatial resolution.

    Objective: Type 2 diabetes mellitus (T2DM) is related to an elevated risk of mild cognitive impairment (MCI). Plasma clusterin is reported associated with the early pathology of Alzheimer's disease (AD) and longitudinal brain atrophy in subjects with MCI. The rs11136000 single nucleotide polymorphism within the clusterin (CLU) gene is also associated with the risk of AD. We aimed to investigate the associations among plasma clusterin, rs11136000 genotype and T2DM-associated MCI. Methods: A total of 231 T2DM patients, including 126 MCI and 105 cognitively healthy controls were enrolled in this study. Demographic parameters were collected and neuropsychological tests were conducted. Plasma clusterin and CLU rs11136000 genotype were examined. Results: Plasma clusterin was significantly higher in MCI patients than in control group (p = 0.007). In subjects with MCI, plasma clusterin level was negatively correlated with Montreal cognitive assessment and auditory verbal learning test_delayed recall scores (p = 0.027 and p = 0.020, respectively). After adjustment for age, educational attainment, and gender, carriers of rs11136000 TT genotype demonstrated reduced risk for MCI compared with the CC genotype carriers (OR = 0.158, χ2 = 4.113, p = 0.043). Multivariable regression model showed that educational attainment, duration of diabetes, high-density lipoprotein cholesterol (HDL-c), and plasma clusterin levels are associated with MCI in T2DM patients. Conclusions: Plasma clusterin was associated with MCI and may reflect a protective response in T2DM patients. TT genotype exhibited a reduced risk of MCI compared to CC genotype. Further investigations should be conducted to determine the role of clusterin in cognitive decline.

    Hip osteoarthritis is very common and costly. The European League Against Rheumatology Committee agenda asks for research to investigate treatments able to slow down the progression of hip osteoarthritis (OA), to delay joint replacement, and to determine the comparative effectiveness and cost-effectiveness of non-surgical and surgical treatment modalities as well as criteria relating to the indications for and timing of total hip replacement (THR). After publishing the results of a randomized controlled trial and a cohort study on the efficacy of Intra-articular sodium hyaluronate (MW 1,500-2,000 kDa) on symptomatic hip OA, we performed this retrospective study in patients suffering from hip OA treated with ultrasound-guided intra-articular injections of HyalOne (Hyalubrix 60 Italian brand name) involving a group of THR expert orthopedic surgeons to appraise whether or not considered eligible for THR and the frequency and timing of THR. Six orthopedists, not routinely performing hip intra-articular injections, each independently assessed whether 176 patients suffering from hip OA and treated with ultrasound-guided intra-articular injections of sodium hyaluronate (MW 1,500-2,000 kDa) were candidates for THR according to the clinical data (age, body mass index, Pain Visual Analog Scale, Lequesne Algofunctional Index, global patient assessment, global physician assessment, nonsteroidal anti-inflammatory drug intake, and hip X-ray) collected at the first intra-articular sodium hyaluronate injection visit and provided as anonymous electronic data. At 24 months, 159 out of 76 (90 %) patients did not undergo to THR. At 48 months, 82 % (N = 144) of the study population treated with intra-articular hyaluronic acid avoided THR. In the group of 93 patients considered candidates for THR (that is, in which 4, 5, or 6 orthopedic surgeons agreed that the patient was a suitable candidate for THR), only 17 had undergone THR, with survival results of 82 % at 24 months.

    Carotid stenosis is known to be an independent risk factor in the transformation process of mild cognitive impairment (MCI) to dementia and is treated by carotid artery stenting (CAS); however, the effects of CAS on cognitive function are unclear. In this study, 240 patients were prospectively assigned to a CAS or control group according to patient preference and underwent detailed neuropsychological examinations (NPEs) before and 6 months after treatment. Cerebral perfusion was assessed with computed tomography perfusion (CTP). Among the 240 patients included in the study, 208 patients completed NPEs at baseline and 6 months after therapy. The patients in the two groups did not differ with regard to baseline characteristics, educational level, vascular risk factors (VRFs) and NPEs prior to therapy. Significant improvements in the Mini-Mental State Examination (MMSE; before, 24.6±1.7 vs. after, 24.8±1.9; P=0.016), Montreal Cognitive Assessment (MOCA; before, 23.7±1.7 vs. after, 24.1±2.0; P=0.006), Fuld Object Memory Evaluation (FOME; before, 13.8±2.2 vs. after, 14.0±2.3; P=0.031) and Wechsler Adult Intelligence Scale-digital span (WAIS-DS; before, 6.7±2.1 vs. after, 6.9±2.3; P=0.040) were observed in the CAS group; however, improvements were not observed in the control group. Of the 84 patients in the CAS group who received CTP follow-up, 72 (86%) presented improvements in ipsilateral brain perfusion 6 months after the procedure; however, no improvement was observed in the control group. Close correlations were identified between the change in perfusion and the change in MMSE (r=0.575) and MOCA (r=0.574). CAS improves global cognitive function in patients with carotid stenosis and MCI and the improvement of cognition is closely related to the improvement of cerebral perfusion. PMID:23596467

    To assess the validity of conducting clinical dysphagia assessments via telerehabilitation, 40 individuals with dysphagia from various etiologies were assessed simultaneously by a face-to-face speech-language pathologist (FTF-SLP) and a telerehabilitation SLP (T-SLP) via an Internet-based videoconferencing telerehabilitation system. Dysphagia status was assessed using a Clinical Swallowing Examination (CSE) protocol, delivered via a specialized telerehabilitation videoconferencing system and involving the use of an assistant at the patient's end of the consultation to facilitate the assessment. Levels of agreement between the FTF-SLP and T-SLP revealed that the majority of parameters reached set levels of clinically acceptable levels of agreement. Specifically, agreement between the T-SLP and FTF-SLP ratings for the oral, oromotor, and laryngeal function tasks revealed levels of exact agreement ranging from 75 to 100% (kappa = 0.36-1.0), while the parameters relating to food and fluid trials ranged in exact agreement from 79 to 100% (kappa = 0.61-1.0). Across the parameters related to aspiration risk and clinical management, exact agreement ranged between 79 and 100% (kappa = 0.49-1.0). The data show that a CSE conducted via telerehabilitation can provide valid and reliable outcomes comparable to clinical decisions made in the FTF environment.

    Objective: Carvedilol is a nonselective third generation β-blocker that does not display the negative effects of traditional β-blockers. Regarding the antioxidant, anti-inflammatory and distinct metabolic properties of carvedilol which are similar to that of high-density lipoprotein (HDL) and paraoxonase 1 (PON1), the present study intends to investigate the effects of carvedilol treatment on malondialdehyde (MDA) and soluble lectin-like ox-low-density lipoprotein (LDL) receptor (sLOX-1) as markers of oxidative stress in association to lipid profiles, apolipoproteins (apo), and PON1 activity in hypertensive patients. Patients and Methods: This clinical trial study was performed on forty patients with mild to moderate essential hypertension. Subjects were studied before and after 2 months treatment with carvedilol, 25 mg daily. Lipids and lipoproteins were measured using a biochemistry analyzer. PON and arylesterase activity were assayed using paraoxon and phenyl acetate as substrates, respectively. MDA was quantified using a chemical colorimetric assay. ELISA was used to measure sLOX-1. Results: Our results showed that carvedilol treatment decreased systolic and diastolic blood pressure as much as forty and 16 mmHg, respectively (P < 0.001). It also increased HDL, total cholesterol, and serum PON1 activity (P < 0.05), but the levels of triglyceride, LDL, apo A-I, and apo B did not significantly change. There was an inverse correlation between serum PON1 activity and serum MDA. Conclusion: This study confirmed the antihypertensive effect of the drug and its beneficial metabolic effects through augmenting HDL and PON1 activity. We propose that the antioxidant effects of carvedilol can be partially attributed to increased PON-1 activity. PMID:27756946

    To construct a cost-minimization model comparing activated prothrombin complex concentrates (APCC) vs. recombinant factor VIIa (rFVIIa) in haemophilia patients with inhibitors from a US third party payer perspective. A literature-based decision model was used to model inhibitor treatment costs and outcomes. As existing clinical trials fail to demonstrate differences in the relative efficacy or safety of APCC vs. rFVIIa, we assumed the same efficacy for both products in the base-case. Regimens of APCC (75 IU kg⁻¹ × 2 doses) and rFVIIa (90 μg kg⁻¹× 3 doses) were assumed according to manufacturer recommendations. If the first-line treatment failed, patients chose to continue the current treatment or switch to another drug. All costs were adjusted to 2009 US dollars. Sensitivity analyses on the infusion frequency, efficacy, unit price, switch rate, re-bleed rate and body weight were performed to assess model robustness. In the base-case, the total medical cost to treat a bleed with APCC or rFVIIa as first-line medication was US$25,969 and US$35,838, respectively. One-way sensitivity analyses showed that results were insensitive to the efficacy of rFVIIa, unit price of APCC or rFVIIa, switch rate, re-bleed rate or body weight. The rFVIIa will reach cost neutrality when the efficacy of APCC is as low as 60%, or rFVIIa is infused only twice for each line, or APCC is infused three times for each line. Two-way sensitivity analyses showed that results were quite sensitive to the assumed infusion frequency for both products. First-line APCC compared with rFVIIa can be a cost-saving alternative for home treatment of mild-to-moderate bleeds in haemophilia patients with inhibitors.

  14. The overall impairment of core executive function components in patients with amnestic mild cognitive impairment: a cross-sectional study

    2012-01-01

    Background It remains unclear how executive function (EF) is affected in the stage of amnestic mild cognitive impairment (aMCI). Previous studies using different methods to assess EF in patients with aMCI have reached inconsistent conclusions. The aim of the study was to explore the characteristics of EF impairments in patients with aMCI. Methods We investigated three core components of EF (i.e., working memory, response inhibition and task switching) based on the theoretical model of EF proposed by Miyake et al. (2000) in 34 aMCI patients and 36 healthy elderly controls using computerized tasks programmed with E-prime (the 2-back task and the keep track task for working memory, the stop-signal task and the Stroop task for response inhibition and the more-odd shifting task for task switching). The overall EF and the three individual EF components were compared between groups. For EF components that were impaired, the extent of impairment was compared using a paired analysis. The aMCI group was further divided into EF-intact and EF-deficit groups according to their performances on the EF tests in clinical neuropsychological assessments. We tested for group differences among the normal controls and the EF-intact and EF-deficit aMCI groups and paid special attention to the comparisons between the EF-intact aMCI group and the control group. Results Compared to the control group, overall EF was significantly impaired in patients with aMCI (Wilks’ λ=0.572,P<0.001). Four tasks (the 2-back task, the keep track task, the stop-signal task and the more-odd shifting task) that tapped the three core components of EF displayed group differences that favored the normal controls. The results of the Stroop task revealed no differences in performance between the two groups. The EF-intact aMCI patients also exhibited significantly impaired capabilities in the four tasks compared to the normal controls. There were no significant differences in the extent of impairment between the

    The elevated level of cerebrospinal fluid (CSF) Tau and phosphorylated Tau181 (p-Tau181) proteins are well established hallmarks of Alzheimer’s disease (AD). Elevated level of p-Tau181 can differentiate AD from other neurodegenerative disease. However, the expression level of these proteins in serum of AD patient is not well set up. This study sought to evaluate the level of Tau and p-Tau181 in serum of AD, and mild cognitive impairment (MCI) patients for an alternative approach to establish protein-based markers by convenient way. Blood samples were collected from 39 AD patients, 37 MCI patients and 37 elderly individuals as controls. The levels of Tau and p-Tau181 in the serum of the different groups were measured by label free real time Surface Plasmon Resonance technology by using specific antibodies, and were further confirmed by the conventional western blot method. An appropriate statistical analysis, including Receiver Operating Characteristic (ROC), was performed. The concentrations of serum Tau and p-Tau181 were significantly higher (p<0.00001) in AD (Tau; 47.49±9.00ng/μL, p-Tau181; 0.161±0.04 ng/μL) compared to MCI (Tau; 39.26±7.78 ng/μL, p-Tau181; 0.135±0.02 ng/μL) and were further higher compared to elderly controls (Tau; 34.92±6.58 ng/μL, p-Tau181; 0.122±0.01 ng/ μL). A significant (p<0.0001) downhill correlation was found between Tau as well as p-Tau181 levels with HMSE and MoCA score. This study for the first time reports the concentration of Tau and p-Tau181 in serum of AD and MCI patients. The cutoff values of Tau and p-Tau181 of AD and MCI patients with sensitivity and specificity reveal that serum level of these proteins can be used as a predictive marker for AD and MCI.

  16. Distinct transthyretin oxidation isoform profile in spinal fluid from patients with Alzheimer’s disease and mild cognitive impairment

    PubMed Central

    2014-01-01

    Background Transthyretin (TTR), an abundant protein in cerebrospinal fluid (CSF), contains a free, oxidation-prone cysteine residue that gives rise to TTR isoforms. These isoforms may reflect conditions in vivo. Since increased oxidative stress has been linked to neurodegenerative disorders such as Alzheimer’s disease (AD) it is of interest to characterize CSF-TTR isoform distribution in AD patients and controls. Here, TTR isoforms are profiled directly from CSF by an optimized immunoaffinity-mass spectrometry method in 76 samples from patients with AD (n = 37), mild cognitive impairment (MCI, n = 17)), and normal pressure hydrocephalus (NPH, n = 15), as well as healthy controls (HC, n = 7). Fractions of three specific oxidative modifications (S-cysteinylation, S-cysteinylglycinylation, and S-glutathionylation) were quantitated relative to the total TTR protein. Results were correlated with diagnostic information and with levels of CSF AD biomarkers tau, phosphorylated tau, and amyloid β1-42 peptide. Results Preliminary data highlighted the high risk of artifactual TTR modification due to ex vivo oxidation and thus the samples for this study were all collected using strict and uniform guidelines. The results show that TTR is significantly more modified on Cys(10) in the AD and MCI groups than in controls (NPH and HC) (p ≤ 0.0012). Furthermore, the NPH group, while having normal TTR isoform distribution, had significantly decreased amyloid β peptide but normal tau values. No obvious correlations between levels of routine CSF biomarkers for AD and the degree of TTR modification were found. Conclusions AD and MCI patients display a significantly higher fraction of oxidatively modified TTR in CSF than the control groups of NPH patients and HC. Quantitation of CSF-TTR isoforms thus may provide diagnostic information in patients with dementia symptoms but this should be explored in larger studies including prospective studies of MCI patients.

    Symptomatic fatigue has not been investigated previously in a multiple sclerosis population. Potential subjects were the 78% of 656 individuals with multiple sclerosis who indicated in a previous study that they experienced symptomatic fatigue. Three hundred nine subjects (60%) returned a follow-up questionnaire on symptomatic fatigue. Ninety percent described fatigue as "tiredness or the need to rest," but 43% of them indicated that "sleepiness" was part of the symptomatology. In 48% fatigue made other MS symptoms worse. Fatigue tended to occur in the late afternoon and evening. It occurred almost daily for more than 66% of the subjects. In 47% of the subjects fatigue usually subsided within a few hours; in other subjects occurrences were of variable length (40%) or lasted between 6 and 24 hours (8%). Ninety percent said that fatigue was worse at warmer environmental temperatures. Fatigue was worse for 83% after "vigorous exercise" and for 64% after "moderate exercise" although 15% reported that moderate exercise helped to reduce fatigue. Meditation, some drugs, and cooling with water reduced fatigue in a majority of the small proportion of the population trying these techniques. A planned daily schedule of activity and rest seemed to be a partially effective response to symptomatic fatigue for the majority of subjects studied.

    Background. Human cytomegalovirus is a leading cause of congenital infection, and there are limited data on prognosis markers in disease development. We aimed to study 3 virology targets (glycoprotein [g]B, gN, and UL144) to assess their correlation with congenital infection and various organ system involvement. Methods. Forty-eight congenital cases and 58 postnatally infected children were included (2003–2014). Genotyping for the 3 targets and distribution among the cohorts were investigated, and the relationship between the gB, gN, and UL144 types with clinical manifestations in congenital infection was also studied. Results. All of the genotypes were similarly represented among cohorts, and the most prevalent were the UL144B, gB1, and gN1 genotypes. The gB2 genotype was associated with abnormal image findings by ultrasound and/or magnetic resonance in congenital infection (odds ratio [OR], 6.2; 95% confidence interval [CI], 1.1–34.3; P = .036); the gN1 genotype was associated with an elevated risk of developing neurological disorders (OR, 7.0; 95% CI, 1.1–45.9; P = .043). Both gN1 and gB2 were independent factors for symptomatic infection. Statistical analyses showed no association between any UL144 genotype and disease severity. Conclusions. All of the genotypes can be involved in congenital infection, although the gB2 and gN1 genotypes might be associated with a more serious illness. PMID:26613094

    Objective: This study investigated white matter integrity in patients with amnestic mild cognitive impairment by diffusion tensor imaging. Methods: A total of 83 patients with amnestic mild cognitive impairment and 85 elderly healthy controls underwent neuropsychological testing and a diffusion tensor imaging scan. Whole-brain white matter data were parcellated into 50 regions based on the anatomical ICBM-DTI-81 atlas, and regional diffusion metrics consisting of fractional anisotropy, mean diffusivity, radial diffusivity, and axial diffusivity were calculated for each region. Diffusion tensor imaging indices were compared between groups, and it was determined that between-group differences were significantly correlated with neurocognitive performance. Results: Relative to the healthy controls group, the amnestic mild cognitive impairment group exhibited poorer cognitive performance in all neuropsychological tests except the complex figure test (p = 0.083) and showed decreased mean fractional anisotropy in the fornix, increased mean diffusivity in the fornix and bilateral uncinate fasciculus, elevated axial diffusivity in the fornix and genu of corpus callosum, and elevated radial diffusivity in the fornix and bilateral uncinate fasciculus (p < 0.05). Behaviorally, integrity of the bilateral uncinate fasciculus was correlated positively with episodic memory function, while left uncinate fasciculus integrity was positively associated with language function in the amnestic mild cognitive impairment group (p < 0.05). Conclusion: White matter abnormalities in neural pathways associated with memory were correlated with neurocognitive deficiencies in amnestic mild cognitive impairment. Given that amnestic mild cognitive impairment is putatively a prodromal syndrome for Alzheimer’s disease, this study furthers our understanding of the white matter changes associated with Alzheimer’s disease pathogenesis in the predementia stage.

    Magnetic resonance imaging (MRI) and brain volumetry allow for the quantification of changes in brain volume using automatic algorithms which are widely used in both, clinical and scientific studies. However, studies comparing the reliability of these programmes are scarce and mainly involved MRI derived from younger healthy controls. This study evaluates the reliability of frequently used segmentation programmes (SPM, FreeSurfer, FSL) using a realistic digital brain phantom and MRI brain acquisitions from patients with manifest Alzheimer's disease (AD, n=34), mild cognitive impairment (MCI, n=60), and healthy subjects (n=32) matched for age and sex. Analysis of the brain phantom dataset demonstrated that SPM, FSL and FreeSurfer underestimate grey matter and overestimate white matter volumes with increasing noise. FreeSurfer calculated overall smaller brain volumes with increasing noise. Image inhomogeneity had only minor, non- significant effects on the results obtained with SPM and FreeSurfer 5.1, but had effects on the FSL results (increased white matter volumes with decreased grey matter volumes). The analysis of the patient data yielded decreasing volumes of grey and white matter with progression of brain atrophy independent of the method used. FreeSurfer calculated the largest grey matter and the smallest white matter volumes. FSL calculated the smallest grey matter volumes; SPM the largest white matter volumes. Best results are obtained with good image quality. With poor image quality, especially noise, SPM provides the best segmentation results. An optimised template for segmentation had no significant effect on segmentation results. While our findings underline the applicability of the programmes investigated, SPM may be the programme of choice when MRIs with limited image quality or brain images of elderly should be analysed.

    Acute symptomatic seizures are seizures occurring in close temporal relationship with an acute central nervous system (CNS) insult. The objective of the study was to determine the frequency of presentation and etiological risk factors of acute symptomatic seizures among adult medical admissions. It was a two-year retrospective study of the medical files of adults patients admitted with acute symptomatic seizures as the first presenting event. There were 94 cases of acute symptomatic seizures accounting for 5.2% (95% CI: 4.17–6.23) of the 1,802 medical admissions during the period under review. There were 49 (52.1%) males and 45 (47.9%) females aged between 18 years and 84 years. The etiological risk factors of acute symptomatic seizures were infections in 36.2% (n = 34) of cases, stroke in 29.8% (n = 28), metabolic in 12.8% (n = 12), toxic in 10.6% (n = 10), and other causes in 10.6% (n = 10). Infective causes were more among those below fifty years while stroke was more in those aged fifty years and above. CNS infections and stroke were the prominent causes of acute symptomatic seizures. This is an evidence of the “double tragedy” facing developing countries, the unresolved threat of infectious diseases on one hand and the increasing impact of noncommunicable diseases on the other one.

    Abstract Although most patients with mild traumatic brain injury (mTBI) recover within 3 months, a subgroup of patients experience persistent symptoms. Yet, the prevalence and predictors of persistent dysfunction in patients with mTBI remain poorly understood. In a longitudinal study, we evaluated predictors of symptomatic and cognitive dysfunction in adolescents and young adults with mTBI, compared with two control groups—patients with orthopedic injuries and healthy uninjured individuals. Outcomes were assessed at 3 months post-injury. Poor symptomatic outcome was defined as exhibiting a symptom score higher than 90% of the orthopedic control (OC) group, and poor cognitive outcome was defined as exhibiting cognitive performance poorer than 90% of the OC group. At 3 months post-injury, more than half of the patients with mTBI (52%) exhibited persistently elevated symptoms, and more than a third (36.4%) exhibited poor cognitive outcome. The rate of high symptom report in mTBI was markedly greater than that of typically developing (13%) and OC (17%) groups; the proportion of those with poor cognitive performance in the mTBI group exceeded that of typically developing controls (15.8%), but was similar to that of the OC group (34.9%). Older age at injury, female sex, and acute symptom report were predictors of poor symptomatic outcome at 3 months. Socioeconomic status was the only significant predictor of poor cognitive outcome at 3 months. PMID:25970233

    Background Cardiac valve calcifications are present in dialysis patients and regarded as dependent on a deranged mineral metabolism. Few data are available for patients with chronic kidney disease (CKD) not on dialysis. This study evaluates the potential association between the extent of cardiac valve calcification and levels of intact parathyroid hormone (i-PTH), phosphorus, calcium, 25-OH vitamin D, fibroblast growth factor 23 (FGF-23), Klotho and C-reactive protein (CRP) simultaneously measured in patients with mild to moderate CKD. Methods Consecutive non-hospitalized patients referring to five nephrology units were evaluated. Inclusion criteria were age >18 years, CKD Stages 3–4, and the presence of aortic and/or mitral valve calcification assessed by echocardiography as routinely clinical evaluation. Patients underwent clinical examination and routine biochemistry. Baseline i-PTH, phosphorus, calcium, 25-OH vitamin D, FGF-23, Klotho and CRP were simultaneously ascertained. Results Extent of aortic valve calcification (n = 100 patients) was moderate in 68 patients and mild in the remaining patients. Mitral valve calcification (n = 96 patients) score was 1, 2 and 3 in 61, 34 and 1 patients, respectively. In univariate analysis, no association was found between extent of mitral valve calcification and markers of mineral metabolism and CRP; aortic valve extent of calcification was positively associated with i-PTH (r2 = 0.212; P = 0.03) and FGF-23 (r2 = 0.272; P = 0.01), and negatively with Klotho (r2 = −0.208; P = 0.04). In multivariable analysis, extent of aortic valve calcification was associated with FGF-23 (P = 0.01) and PTH (P = 0.01) levels. Conclusions Extent of aortic valve calcification is associated to FGF-23 and PTH in naïve CKD patients with mild to moderate CKD. Further studies should examine whether FGF-23 assay should be included in routine clinical evaluation of CKD as part of cardiovascular risk stratification. PMID:26613033

    OBJECTIVES: This study sought to verify the effects of acupuncture as an adjuvant treatment for the control of asthma. METHODS: This was a randomized, controlled, crossover trial conducted at the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. A total of 74 patients with mild/moderate, persistent asthma were randomized into two therapeutic groups: Group A – 31 patients underwent 10 real weekly acupuncture sessions, followed by a 3-week washout period and 10 sham weekly acupuncture sessions; and Group B - 43 patients underwent 10 sham weekly acupuncture sessions, followed by a 3-week washout period and 10 real weekly acupuncture sessions. Patients used short- and long-acting β-2 agonists and inhaled corticosteroids when necessary. Prior to treatment and after each period of 10 treatment sessions, the patients were evaluated for spirometry, induced sputum cell count, exhaled nitric oxide (NO) and with the Short Form 36 (SF-36) and Questionnaire on Quality of Life-Asthma (QQLA) questionnaires. Daily peak flow and symptom diaries were registered. The level of significance adopted was 5% (α=0.05). RESULTS: In Group B, after real acupuncture, there was a decrease in eosinophils (p=0.035) and neutrophils (p=0.047), an increase in macrophages (p=0.001) and an improvement in peak flow (p=0.01). After sham acupuncture treatment, patients experienced less coughing (p=0.037), wheezing (p=0.013) and dyspnea (p=0.014); similarly, after real acupuncture, patients reported less coughing (p=0.040), wheezing (p=0.012), dyspnea (p<0.001) and nocturnal awakening episodes (p=0.009). In Group A, there was less use of rescue medication (p=0.043). After the sham procedure, patients in Group A experienced less coughing (p=0.007), wheezing (p=0.037), dyspnea (p<0.001) and use of rescue medication (p<0.001) and after real acupuncture, these patients showed improvements in functional capacity (p=0.004), physical aspects (p=0.002), general health status (p<0

    The purpose of this study was to determine patient-reported outcomes of patients with mild to moderate developmental dysplasia of the hip (DDH) and femoroacetabular impingement (FAI) undergoing arthroscopy of the hip in the treatment of chondrolabral pathology. A total of 28 patients with a centre-edge angle between 15° and 19° were identified from an institutional database. Their mean age was 34 years (18 to 53), with 12 female and 16 male patients. All underwent labral treatment and concomitant correction of FAI. There were nine reoperations, with two patients requiring revision arthroscopy, two requiring periacetabular osteotomy and five needing total hip arthroplasty. Patients who required further major surgery were more likely to be older, male, and to have more severe DDH with a larger alpha angle and decreased joint space. At a mean follow-up of 42 months (24 to 89), the mean modified Harris hip score improved from 59 (20 to 98) to 82 (45 to 100; p < 0.001). The mean Western Ontario and McMaster Universities Osteoarthritis Index score improved from 30 (1 to 61) to 16 (0 to 43; p < 0.001). Median patient satisfaction was 9.0/10 (1 to 10). Patients reported excellent improvement in function following arthroscopy of the hip. This study shows that with proper patient selection, arthroscopy of the hip can be successful in the young patient with mild to moderate DDH and FAI. PMID:26430004

    Spasticity represents a common troublesome symptom in patients with multiple sclerosis (MS). Treatment of spasticity remains difficult, which has prompted some patients to self-medicate with and perceive benefits from cannabis. Advances in the understanding of cannabinoid biology support these anecdotal observations. Various clinical reports as well as randomized, double-blind, placebo-controlled studies have now demonstrated clinical efficacy of cannabinoids for the treatment of spasticity in MS patients. Sativex is a 1:1 mix of delta-9-tetrahydocannabinol and cannabidiol extracted from cloned Cannabis sativa chemovars, which recently received a label for treating MS-related spasticity in Germany. The present article reviews the current understanding of cannabinoid biology and the value of cannabinoids as a symptomatic treatment option in MS. PMID:22080198

    Risperidone is a heterocyclic neuroleptic with prominent antiserotoninergic (5HT2) as well as antidopaminergic (D2) activity. We studied the efficacy of risperidone in the treatment of idiopathic and symptomatic dystonias in seven patients using the Fahn and Marsden rating scale for torsion dystonia before and after four weeks of treatment (2-6 mg/day). The twisting and involuntary movements with abnormal postures decreased in all the patients treated, with a statistically significant mean improvement (41%; p = 0.009, CI 95%). Our results suggest that risperidone is useful in idiopathic and symptomatic dystonia. PMID:10938193

    Two cases of unilateral hip pain are reported in which MR arthrography demonstrated a prominent band medial to the ligamentum teres, running in the AP direction, consistent with a hip plica. Both patients underwent hip arthroscopy with resection of the band. No labral tear or additional intra-articular pathological features was identified in either case. Both patients became asymptomatic following surgery and have remained such. The pathology report demonstrated the specimens to be a synovial band with fibroconnective tissue. This is the first MR arthrographic report of the identification and resection of a symptomatic hip plica. The symptomatic plica may represent an alternative diagnosis for mechanical hip pain.

    Objectives: The primary objective was to compare a single, 6 ml, intra-articular injection of hylan G-F 20 with placebo in patients with symptomatic knee osteoarthritis. The safety of a repeat injection of hylan G-F 20 was also assessed. Methods: Patients with primary osteoarthritis knee pain were randomly assigned to arthrocentesis plus a 6 ml intra-articular injection of either hylan G-F 20 or placebo in a prospective, double-blind (one injector/one blinded observer) study. Results were evaluated at 4, 8, 12, 18 and 26 weeks post-injection. The primary outcome criterion was change from baseline over 26 weeks in Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index A pain. Secondary outcome measures included WOMAC A1 and C, patient global assessment (PGA) and clinical observer global assessment (COGA) and Outcome Measures in Rheumatology, Osteoarthritis Research Society International responder rates. A 4-week, open, repeat treatment phase evaluated safety only. Results: A total of 253 patients (Kellgren–Lawrence grade II or III) was randomly assigned. Patients receiving hylan G-F 20 experienced statistically significantly greater improvements in WOMAC A pain scores (−0.15, SE 0.076, p = 0.047), and several of the secondary outcome measures (WOMAC A1, PGA and COGA), than patients receiving placebo. There was no difference between the safety results of the two groups. No increased risk of local adverse events was observed in the open, repeat treatment phase. Conclusions: This placebo-controlled study demonstrated that, in patients with knee osteoarthritis, a single 6 ml intra-articular injection of hylan G-F 20 is safe and effective in providing statistically significant, clinically relevant pain relief over 26 weeks, with a modest difference versus placebo.

    Background Synaptic loss is a major hallmark of Alzheimer’s disease (AD). Disturbed organisation of large-scale functional brain networks in AD might reflect synaptic loss and disrupted neuronal communication. The medical food Souvenaid, containing the specific nutrient combination Fortasyn Connect, is designed to enhance synapse formation and function and has been shown to improve memory performance in patients with mild AD in two randomised controlled trials. Objective To explore the effect of Souvenaid compared to control product on brain activity-based networks, as a derivative of underlying synaptic function, in patients with mild AD. Design A 24-week randomised, controlled, double-blind, parallel-group, multi-country study. Participants 179 drug-naïve mild AD patients who participated in the Souvenir II study. Intervention Patients were randomised 1∶1 to receive Souvenaid or an iso-caloric control product once daily for 24 weeks. Outcome In a secondary analysis of the Souvenir II study, electroencephalography (EEG) brain networks were constructed and graph theory was used to quantify complex brain structure. Local brain network connectivity (normalised clustering coefficient gamma) and global network integration (normalised characteristic path length lambda) were compared between study groups, and related to memory performance. Results The network measures in the beta band were significantly different between groups: they decreased in the control group, but remained relatively unchanged in the active group. No consistent relationship was found between these network measures and memory performance. Conclusions The current results suggest that Souvenaid preserves the organisation of brain networks in patients with mild AD within 24 weeks, hypothetically counteracting the progressive network disruption over time in AD. The results strengthen the hypothesis that Souvenaid affects synaptic integrity and function. Secondly, we conclude that advanced EEG

    Objective We aimed to establish the cut-off point of the Montreal Cognitive Assessment (MoCA-Beijing) in screening for cognitive impairment (CI) within 2 weeks of mild stroke or transient ischaemic attack (TIA). Methods A total of 80 acute mild ischaemic stroke patients and 22 TIA patients were recruited. They received the MoCA-Beijing and a formal neuropsychological test battery. CI was defined by 1.5 SD below the established norms on a formal neuropsychological test battery. Results Most stroke and TIA patients were in their 50s (53.95±11.43 years old), with greater than primary school level of education. The optimal cut-off point for MoCA-Beijing in discriminating patients with CI from those with no cognitive impairment (NCI) was 22/23 (sensitivity 85%, specificity 88%, positive predictive value=91%, negative predictive value=80%, classification accuracy=86%). The predominant cognitive deficits were characteristic of frontal-subcortical impairment, such as visuomotor speed (46.08%), attention/executive function (42.16%) and visuospatial ability (40.20%). Conclusions A MoCA-Beijing cut-off score of 22/23 is optimally sensitive and specific for detecting CI after mild stroke, and TIA in the acute stroke phase, and is recommended for routine clinical practice.

    Concussion is increasingly recognized as a major public health issue. Most patients will return to baseline and experience full recovery, although a subset experiences persistent symptoms. Newer animal models and imaging studies are beginning to demonstrate that metabolic and neurovascular resolution may actually take longer than symptomatic recovery. Repeat traumatic brain injury within the metabolic window of dysfunction may result in worsened symptoms and prolonged recovery. The true risk for second impact syndrome appears to be small, and development of cerebral edema after a mild impact may be related to genetic risks rather than serial impacts. PMID:27637394

    Approximately, 70 % of acute myocardial infarctions are known to develop from mild atherosclerotic lesions. Therefore, it is important to evaluate mild coronary plaques to prevent acute coronary syndrome (ACS). The aim of the present study was to investigate the effects of exercise-based cardiac rehabilitation (CR) on mild coronary atherosclerosis in non-culprit lesions in patients with ACS. Forty-one men with ACS who underwent emergency percutaneous coronary interventions and completed a 6-month follow-up were divided into CR and non-CR groups. Quantitative coronary angiography (QCA) was performed using the automatic edge detection program. The target lesion was a mild stenotic segment (10-50 % stenosis) at the distal site of the culprit lesion, and the segment to be analyzed was determined at a segment length ranging from 10 to 15 mm. The plaque area was significantly decreased in the CR group after 6 months, but was significantly increased in the non-CR group (P < 0.05). The low-density lipoprotein (LDL) cholesterol, LDL/high-density lipoprotein (HDL) ratio and high-sensitivity C-reactive protein (Hs-CRP) levels were significantly reduced in both groups (P < 0.01). Peak VO2 in the CR group was significantly increased (P < 0.01). Changes in the plaque area correlated with those in Hs-CRP in both groups, while that association with those in HDL-C was observed in only CR group. Stepwise regression analysis revealed the decrease in Hs-CRP as an independent predictor of plaque area regression in the CR group. CR prevented the progression of mild coronary atherosclerosis in patients with ACS. PMID:25896129

    The relationships between personality and psychiatric symptoms and long-lasting physical symptoms were assessed in 88 neck sprain patients injured in car accidents. The Millon Clinical Multiaxial Inventory (MCMI-I) was completed at time of occurrence (intake) and 6 months after the injury. The neck sprain patients were divided into three subgroups according to symptoms 6 months after the accident. In addition, the total neck sprain group was compared with three other subject groups. The results indicated that the three neck sprain subgroups did not differ on the MCMI-I neither at intake nor 6 months later. The total neck sprain patients group was significantly different from patients with major depression on all scales of the MCMI-I, but not significantly different compared to patients with localized musculoskeletal pain. Compared to a group of health personnel, there were only a few significant differences. The study does not support the view that premorbid personality traits can predict outcome for neck sprain patients.

    Verbal fluency is the ability to produce a satisfying sequence of spoken words during a given time interval. The core of verbal fluency lies in the capacity to manage the executive aspects of language. The standard scores of the semantic verbal fluency test are broadly used in the neuropsychological assessment of the elderly, and different analytical methods are likely to extract even more information from the data generated in this test. Graph theory, a mathematical approach to analyze relations between items, represents a promising tool to understand a variety of neuropsychological states. This study reports a graph analysis of data generated by the semantic verbal fluency test by cognitively healthy elderly (NC), patients with Mild Cognitive Impairment—subtypes amnestic (aMCI) and amnestic multiple domain (a+mdMCI)—and patients with Alzheimer's disease (AD). Sequences of words were represented as a speech graph in which every word corresponded to a node and temporal links between words were represented by directed edges. To characterize the structure of the data we calculated 13 speech graph attributes (SGA). The individuals were compared when divided in three (NC—MCI—AD) and four (NC—aMCI—a+mdMCI—AD) groups. When the three groups were compared, significant differences were found in the standard measure of correct words produced, and three SGA: diameter, average shortest path, and network density. SGA sorted the elderly groups with good specificity and sensitivity. When the four groups were compared, the groups differed significantly in network density, except between the two MCI subtypes and NC and aMCI. The diameter of the network and the average shortest path were significantly different between the NC and AD, and between aMCI and AD. SGA sorted the elderly in their groups with good specificity and sensitivity, performing better than the standard score of the task. These findings provide support for a new methodological frame to assess the

    Patients with Alzheimer's disease after an initial response to cholinesterase inhibitors may complain a later lack of efficacy. This, in association with incident neuropsychiatric symptoms, may worsen patient quality of life. Thus, the switch to another cholinesterase inhibitor could represent a valid therapeutic strategy. The aim of this study was to investigate the effectiveness of the switch from one to another cholinesterase inhibitor on cognitive and affective symptoms in mild to moderate Alzheimer disease patients. Four hundred twenty-three subjects were included from the EVOLUTION study, an observational, longitudinal, multicentre study conducted on Alzheimer disease patients who switched to different cholinesterase inhibitor due either to lack/loss of efficacy or response, reduced tolerability or poor compliance. All patients underwent cognitive and neuropsychiatric assessments, carried out before the switch (baseline), and at 3 and 6-month follow-up. A significant effect of the different switch types was found on Mini-Mental State Examination score during time, with best effectiveness on mild Alzheimer's disease patients switching from oral cholinesterase inhibitors to rivastigmine patch. Depressive symptoms, when measured using continuous Neuropsychiatric Inventory values, decreased significantly, while apathy symptoms remained stable over the 6 months after the switch. However, frequency of both depression and apathy, when measured categorically using Neuropsychiatric Inventory cut-off scores, did not change significantly during time. In mild to moderate Alzheimer disease patients with loss of efficacy and tolerability during cholinesterase inhibitor treatment, the switch to another cholinesterase inhibitor may represent an important option for slowing cognitive deterioration. The evidence of apathy stabilization and the positive tendency of depressive symptom improvement should definitively be confirmed in double-blind controlled studies.

    Case series Patient: Male, 87 • Male, 62 Final Diagnosis: Spinal subdural abscess Symptoms: Fever • pain • weakness Medication: — Clinical Procedure: Laminectomy • durotomy • drainage • debridement Specialty: Neurosurgery Objective: Rare disease Background: Spinal subdural abscesses, also known as empyemas, are rare infectious lesions, the exact incidence of which is unknown. Presentation is typically dramatic, with back pain, fever, motor, and sensory deficits. Rapid identification and surgical intervention with laminectomy, durotomy, and washout provides the best outcomes. While hematogenous spread of an extra-spinal infection is the most common cause of this condition, a significant number of cases result from iatrogenic mechanisms, including lumbar punctures, epidural injections, and surgery. Case Report: Here we present 2 cases: 1) an 87-year-old man with type 2 diabetes, schizophrenia, mild cognitive impairment, and symptomatic lumbar spinal stenosis and 2) a 62-year-old man with a prior L3–4 spinal fusion with symptomatic lumbar spinal stenosis. In both cases, patients underwent laminectomy for spinal stenosis and developed epidural abscess. Following successful drainage of the epidural abscess, they continued to be symptomatic, and repeat imaging revealed the presence of a subdural abscess that was subsequently evacuated. Case 1 had significant improvement with residual lower-extremity weakness, while Case 2 made a complete neurological recovery. Conclusions: These cases illustrate patients at increased risk for developing this rare spinal infection, and demonstrate that rapid recognition and surgical treatment is key to cure and recovery. Review of the literature highlights pertinent risk factors and demonstrates nearly one-third of reported cases have an iatrogenic etiology. The cases presented here demonstrate that a subdural process should be suspected in any patient with intractable pain following treatment of an epidural abscess. PMID

    This exploratory clinical trial aims to assess the effect on visual acuity and central corneal thickness of an unpreserved hypertonic ophthalmic solution containing sodium chloride (5%) and sodium hyaluronate, in patients with chronic corneal edema caused by endothelial disease reducing their visual acuity. Twenty patients were enrolled and treated with the hypertonic solution (1 to 2 drops per eye, 4 times a day over 28 days). Progression of visual acuity (ETDRS score) and corneal thickness (ultrasonic pachymetry) was measured from baseline (without treatment) through the treatment period (Day 7 and Day 28). The analyses were performed on 18 patients (Full Analysis Set [FAS] population). The causes of corneal edema were Fuchs endothelial dystrophy in 10 cases and post-cataract surgery endothelial decompensation in 8 patients. The mean visual acuity values for the FAS population compared between baseline (Day-7) and one week of treatment (Day+7) show a significant 5-point VA improvement (P<0.001 paired Wilcoxon test). For corneal thickness, there was also a significant decrease (P=0.033 paired Wilcoxon test). Functional improvement was observed at 28 days of instillation. No adverse events were recorded during the clinical study. In conclusion, the unpreserved hyperosmolar solution containing sodium chloride and sodium hyaluronate significantly improved ETDRS visual acuity after one week of use. In this clinical trial, the solution also showed excellent tolerability results.

  2. Comparative analysis of the diagnostic and prognostic value of exercise ECG and thallium-201 scintigraphic markers of myocardial ischemia in asymptomatic and symptomatic patients

    1989-08-01

    A considerable amount of data now exists that indicates that exercise ECG--due to its suboptimal sensitivity and specificity--has limited diagnostic and prognostic value in asymptomatic subjects, patients with chest pain of unclear etiology or those with chronic stable angina pectoris, and in patients recovering from acute myocardial infarction. Because of this and the well-recognized advantages of thallium-201 scintigraphy, there appears to be a strong rationale for recommending exercise perfusion imaging, rather than exercise ECG alone, as the preferred method for detecting CAD and staging its severity. This recommendation seems justified given the fact that (1) thallium-201 scintigraphy is far more sensitive and specific in detecting myocardial ischemia than exercise testing; (2) unlike stress ECG, thallium-201 scintigraphy can localize ischemia to a specific area of areas subtended by a specific coronary artery; and (3) thallium-201 scintigraphy has been shown to be more reliable to risk stratification of individual patients than exercise testing alone. The more optimal prognostic efficiency of thallium-201 scintigraphy is due, in part, to the fact that the error rate in falsely classifying patients as low-risk is substantially and significantly smaller with thallium-201 scintigraphy than with stress ECG. 52 references.

    Objectives One quarter of HIV-1 positive individuals in Sweden present for care with HIV or AIDS associated conditions without an HIV test (missed presentations) and 16% report neglect of such symptoms. The objective of this study was to identify risk factors for these missed opportunities of HIV-1 diagnosis. Methods A national study, recruiting 409 newly diagnosed HIV-1 infected adults over a 2.5-year period, was performed. Logistic regression models tested the relationship between missed presentation and patient’s neglect versus socio-demographic and behavioural risk factors. Additionally the initiator of the HIV test was assessed. Results The odds for a missed presentation was lower for migrants (from East Europe, Asia, and Pacific (East): OR 0.4 (0.2–0.8); Sub-Saharan Africa (SSA): 0.3 (0.2–0.6); other: 0.5 (0.2–1.0)), compared to patients born in Sweden, just as symptoms neglected by the patient (East (0.3 (0.1–1.0); SSA (0.4 (0.2–0.8)). The latter was also lower for men who have sex with men (0.5 (0.2–1.0)), compared to patients infected heterosexually. Patients infected in the East, with present/previous substance use or a previous negative HIV test were more likely to take the initiative to test on their own, whereas those >50 years and with a previously missed presentation had significantly reduced odds, p<0.05. Conclusions Individuals without epidemiological indicators of HIV are more likely to have a history of missed presentations, to neglect symptoms and are less prone to take an initiative to test for HIV themselves. It is important to further implement testing to include all patients with symptoms and conditions indicative of HIV. PMID:27603207

    2016-01-01

    In this narrative review we focus on acute symptomatic seizures occurring in subjects with electrolyte disturbances. Quite surprisingly, despite its clinical relevance, this issue has received very little attention in the scientific literature.

    Spinal subarachnoid spread is not uncommon in brain oligodendrogliomas; on the other hand, symptomatic involvement of the spinal cord and cauda is very rare, with only 16 reported cases. We report the case of a 41-year-old man who underwent resection of a low-grade frontal oligodendroglioma 4 years previously. He was again observed because of bilateral sciatic pain followed by left leg paresis. A spine MRI showed an intramedullary T12-L1 tumor with root enhancement. At operation, an intramedullary anaplastic oligodendroglioma with left exophytic component was found and partially resected. Two weeks later, a large left frontoparietal anaplastic oligodendroglioma was diagnosed and completely resected. The patient was neurologically stable for 8 months and died 1 year after the spinal surgery because of diffuse brain and spinal leptomeningeal spread. The review of the reported cases shows that spinal symptomatic metastases can occur in both low-grade and anaplastic oligodendrogliomas, even many years after surgery of the primary tumor; however, they exceptionally occur as first clinical manifestation or as anaplastic progression. The spinal seeding represents a negative event leading to a short survival.

    The treatment of metastatic castrate-resistant prostate cancer (mCRPC) has grown over the past decade. The majority of patients develop bone metastases, which pose a significant burden on morbidity and mortality, especially skeletal-related events. Whilst demonstrating a favourable safety profile and improving symptoms, radiopharmaceuticals have until recently failed to show a survival benefit. However, since the large phase III randomized ALSYMPCA trial, the calcium mimetic properties of radium-223 (Ra223) have improved patients' quality of life and improved survival whilst keeping toxicities to a minimum. This review article summarizes the clinical data including our real life experience on the usage of the alpha emitter Ra223 in mCRPC, paying particular attention to how clinicians should best monitor response.

    Thirteen patients with mild hypertension (untreated diastolic blood pressure of 95 to 114 mmHg) received, in random order, three successive treatments of four weeks with placebo, spirapril (6 mg daily), or hydrochlorothiazide (HCT2) (24 mg daily). At the end of each treatment, blood samples for assessment of platelet aggregation and platelet release of platelet factor 4 (PF4) and for assessment of fibrinolysis, estimated by tissue plasminogen activator (t-PA), plasminogen activator inhibitor-type 1 (PAI-1), and euglobulin clot lysis time (ECLT), were taken, first at rest, then immediately after five to ten minutes of vigorous exercise, and finally after the subsequent hour of recovery rest. Platelet aggregation induced in vitro by adrenaline significantly decreased during treatment with HCT2, the threshold rising to 10 microM as compared with 1.0 with placebo (P < 0.05) at rest, and the threshold for adenosine diphosphate (ADP) aggregation also rose, from 2 microM to 4 (NS). The resting plasma PF4 value fell, although not significantly, during HCT2 treatment from the placebo value of 3.28 to 2.56 ng/mL. During spirapril treatment there was no change in the threshold of either adrenaline or ADP for aggregation of platelets sampled at rest, and the PF4 plasma levels showed no significant reductions at rest. However, during exercise PF4 showed an approximate doubling of the resting value irrespective of therapy. This exercise-induced increase in PF4 was significantly reduced by spirapril as compared with placebo (P < 0.05). ECLT and t-PA did not shift significantly from the placebo level during either therapy. PAI-1 did not change during spirapril therapy, but during HCT2 treatment it fell, although not significantly, to 9.36 IU/mL from 15.91 with placebo (NS). Spirapril and HCT2 did not produce any unwanted side effect on platelet function or fibrinolysis. HCT2 seems to decrease platelet activity at rest, whereas spirapril seems to some extent to decrease platelet

    BACKGROUND—It is desirable to prescribe the minimal effective dose of inhaled steroids to control asthma. To ensure that inflammation is suppressed whilst using the lowest possible dose, a sensitive and specific method for assessing airway inflammation is needed.
METHODS—The usefulness of exhaled nitric oxide (NO), sputum eosinophils, and methacholine airway responsiveness (PC20) for monitoring airway inflammatory changes following four weeks of treatment with an inhaled corticosteroid (budesonide via Turbohaler) were compared. Mild stable steroid naive asthmatic subjects were randomised into two double blind, placebo controlled studies. The first was a parallel group study involving three groups receiving either 100 µg/day budesonide (n = 8), 400 µg/day budesonide (n = 7), or a matched placebo (n = 6). The second was a crossover study involving 10 subjects randomised to receive 1600 µg budesonide or placebo. The groups were matched with respect to age, PC20, baseline FEV1 (% predicted), exhaled NO, and sputum eosinophilia.
RESULTS—There were significant improvements in FEV1 following 400 µg and 1600 µg budesonide (11.3% and 6.5%, respectively, p<0.05). This was accompanied by significant reductions in eosinophil numbers in induced sputum (0.7 and 0.9 fold, p<0.05). However, levels of exhaled NO were reduced following each budesonide dose while PC20 was improved only with 1600 µg budesonide. These results suggest that exhaled NO and PC20 may not reflect the control of airway inflammation as accurately as the number of eosinophils in sputum. There were dose dependent changes in exhaled NO, sputum eosinophils, and PC20 to inhaled budesonide but a plateau response of exhaled NO was found at a dose of 400 µg daily.
CONCLUSION—Monitoring the number of eosinophils in induced sputum may be the most accurate guide to establish the minimum dose of inhaled steroids needed to control inflammation. This, however, requires further studies involving a larger

    Ecchordosis physaliphora (EP) is a rare, benign tumor derived from the notochordal remnants. Usually slow growing with an indolent course, most cases are incidental findings on autopsy. Limited data exists on symptomatic patients with EP. Diagnosis mainly relies on correlating histopathologic findings confirming the notochordal elements with MRI. We herein present a middle aged woman with symptomatic EP in the pre-pontine cistern that mimicked an arachnoid cyst on preoperative scans. Additionally, we emphasize the pathological and radiological characteristics of EP that could aid in prompt diagnosis of the lesion with emphasis on considering EP as a differential for mass lesions localized in the pre-pontine cistern.

    Flexible flatfoot is a common deformity in pediatric and adult populations. In this study, we aimed to evaluate the functional and radiographic results of subtalar arthroereisis in adult patients with symptomatic flexible flatfoot. We included 26 feet in 16 patients who underwent subtalar arthroereisis for symptomatic flexible flatfoot. Radiographic examination included calcaneal inclination angle, lateral talocalcaneal angle, Meary’s angle, anteroposterior talonavicular angle, and Kite’s angle. The clinical assessment was based on the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scale and a visual analog scale (VAS). The mean follow-up was 15.1±4.7 months. The mean preoperative AOFAS score was 53±6.6, while the mean AOFAS score at the last follow-up visit was 75±11.2 (P<0.05). The mean visual analog scale score was 6.9±0.6 preoperatively and 4.1±1.4 at the last follow-up visit (P<0.05). The mean preoperative and postoperative values measured were 13.4°±3.3° and 14.6°±2.7° for calcaneal inclination angles (P<0.05); 35.7°±6.9° and 33.2°±5.3° for lateral talocalcaneal angles (P>0.05); 8°±5.3° and 3.3±3 for Meary’s angles (P<0.05); 5.6°±3.5° and 2.6°±1.5° for anteroposterior talonavicular angles (P<0.05); and 23.7°±6.1° and 17.7°±5° for Kite’s angles, respectively (P<0.05). Implants were removed in three feet (11.5%). Subtalar arthroereisis is a minimally invasive procedure that can be used in the surgical treatment of adults with symptomatic flexible flatfoot. This procedure provided radiological and functional recovery in our series of patients. PMID:26527876

    Purpose. To report 5-year contrast-enhanced magnetic resonance imaging findings of the REST trial recruits who underwent either uterine artery embolization (UAE) or myomectomy. Methods. A total of 157 patients were randomized to UAE or surgery (hysterectomy or myomectomy). Ninety-nine patients who had UAE and eight patients who had myomectomy were analyzed. MRI scans at baseline, 6 months, and 5 years were independently interpreted by two radiologists. Dominant fibroid diameter, uterine volume, total fibroid infarction (complete 100 %, almost complete 90-99 %, partial <90 %), and new fibroid formation were the main parameters assessed and related to the need for reintervention. Results. In the UAE group, mean {+-} standard deviation uterine volume was 670 {+-} 503, 422 {+-} 353, and 292 {+-} 287 mL at baseline, 6 months, and 5 years, respectively. Mean dominant fibroid diameter was 7.6 {+-} 3.0, 5.8 {+-} 2.9, and 5 {+-} 2.9 cm at baseline, 6 months, and 5 years. Fibroid infarction at 6 months was complete in 35 % of women, almost complete in 29 %, and partial in 36 %. Need for reintervention was 19, 10, and 33 % in these groups, respectively (p = 0.123). No myomectomy cases had further intervention. At 5 years, the prevalence of new fibroid was 60 % in the myomectomy group and 7 % in the UAE group (p = 0.008). Conclusion. There is a further significant reduction in both uterine volume and dominant fibroid diameter between 6 months and 5 years after UAE. Complete fibroid infarction does not translate into total freedom from a subsequent reintervention. New fibroid formation is significantly higher after myomectomy.

    Chronic thromboembolic disease is characterised by persistent pulmonary thromboembolic occlusions without pulmonary hypertension. Early surgical treatment with pulmonary endarterectomy may improve symptoms and prevent disease progression. We sought to assess the outcome of pulmonary endarterectomy in symptomatic patients with chronic thromboembolic disease. Patients with symptomatic chronic thromboembolic disease and a mean pulmonary artery pressure <25 mmHg at baseline with right heart catheterisation and treated with pulmonary endarterectomy between January 2000 and July 2013 were identified. Patients were reassessed at 6 months and at 1 year following surgery. A total of 42 patients underwent surgery and the median length of stay in hospital was 11 days. There was no in-hospital mortality but complications occurred in 40% of patients. At 1 year, following surgery, 95% of the patients remained alive. There was a significant symptomatic improvement with 95% of patients in the New York Heart Association functional classes I or II at 6 months. There was a significant improvement in quality of life assessed by the Cambridge pulmonary hypertension outcome review questionnaire. In this carefully selected cohort of chronic thromboembolic disease patients, pulmonary endarterectomy resulted in significant improvement in symptoms and quality of life. Appropriate patient selection is paramount given the known surgical morbidity and mortality, and surgery should only be performed in expert centres.

    Summary Somatic point mutations in the PH domain of SH2B3 (LNK), an adaptor protein that is highly expressed in haematopoietic cells, were recently described in patients with myeloproliferative neoplasms. We studied the effect of these mutations on the JAK2 signalling pathway in cells expressing either wild type JAK2 or the JAK2 V617F mutation. Compared to wild type SH2B3, PH domain mutants have mild loss of function, with no evidence for a dominant-negative effect. Mutants retain binding capacity for JAK2, an established SH2B3 target, as well as for the adaptor proteins 14-3-3 and CBL. Our data suggest that the loss of SH2B3 inhibitory function conferred by the PH domain mutations is mild and may collaborate with JAK2 V617F and CBL mutations in order to promote either the development or the progression of myeloproliferative neoplasms.

    We report a laparoscopic approach to the drainage and ablation of symptomatic simple renal cysts. Ten patients with chronic pain, 6 of whom failed primary aspiration, underwent laparoscopic cyst ablation: 6 had solitary renal cysts, 3 had multiple cysts and 1 had a peripelvic cyst. The approach was transabdominal in 9 patients and extraperitoneal in 1. Intraoperatively, cyst fluid was obtained for cytological examination, and cyst walls were excised and sent for pathological examination. When possible, the remaining inner cyst walls were fulgurated to prevent recurrence. Mean total operating room time was 2 hours 27 minutes and blood loss was minimal. The sole complication was a postoperative retroperitoneal hematoma, which was managed conservatively. Malignancy was diagnosed in 2 patients, each of whom had a negative preoperative aspiration. These patients subsequently underwent radical nephrectomy. All remaining patients were asymptomatic at a mean followup of 10 months. Laparoscopic ablation of renal cysts is a safe and effective alternative to open surgery in patients who have failed conservative measures. Preoperative and intraoperative evaluation for malignancy should be performed.

    Abstract Previous studies of small cohorts have implicated several circulating cytokines with progression of chronic hepatitis B (CHB). However, to date there have been no reliable biomarkers for assessing histological liver damage in CHB patients with normal or mildly elevated alanine aminotransferase (ALT). The aim of the present study was to investigate the association between circulating cytokines and histological liver damage in a large cohort. Also, this study was designed to assess the utility of circulating cytokines in diagnosing liver inflammation and fibrosis in CHB patients with ALT less than 2 times the upper limit of normal range (ULN). A total of 227 CHB patients were prospectively enrolled. All patients underwent liver biopsy and staging by Ishak system. Patients with at least moderate inflammation showed significantly higher levels of CXCL-11, CXCL-10, and interleukin (IL)-2 receptor (R) than patients with less than moderate inflammation (P < 0.001). Patients with significant fibrosis had higher levels of IL-8 (P = 0.027), transforming growth factor alpha (TGF-α) (P = 0.011), IL-2R (P = 0.002), and CXCL-11 (P = 0.032) than the group without significant fibrosis. In addition, 31.8% and 29.1% of 151 patients with ALT < 2 × ULN had at least moderate inflammation and significant fibrosis, respectively. Multivariate analysis demonstrated that CXCL-11 was independently associated with at least moderate inflammation, and TGF-α and IL-2R independently correlated with significant fibrosis in patients with ALT < 2 × ULN. Based on certain cytokines and clinical parameters, an inflammation-index and fib-index were developed, which showed areas under the receiver operating characteristics curve (AUROC) of 0.75 (95% CI 0.66–0.84) for at least moderate inflammation and 0.82 (95% CI 0.75–0.90) for significant fibrosis, correspondingly.

    BACKGROUND Spinal subdural abscesses, also known as empyemas, are rare infectious lesions, the exact incidence of which is unknown. Presentation is typically dramatic, with back pain, fever, motor, and sensory deficits. Rapid identification and surgical intervention with laminectomy, durotomy, and washout provides the best outcomes. While hematogenous spread of an extra-spinal infection is the most common cause of this condition, a significant number of cases result from iatrogenic mechanisms, including lumbar punctures, epidural injections, and surgery. CASE REPORT Here we present 2 cases: 1) an 87-year-old man with type 2 diabetes, schizophrenia, mild cognitive impairment, and symptomatic lumbar spinal stenosis and 2) a 62-year-old man with a prior L3-4 spinal fusion with symptomatic lumbar spinal stenosis. In both cases, patients underwent laminectomy for spinal stenosis and developed epidural abscess. Following successful drainage of the epidural abscess, they continued to be symptomatic, and repeat imaging revealed the presence of a subdural abscess that was subsequently evacuated. Case 1 had significant improvement with residual lower-extremity weakness, while Case 2 made a complete neurological recovery. CONCLUSIONS These cases illustrate patients at increased risk for developing this rare spinal infection, and demonstrate that rapid recognition and surgical treatment is key to cure and recovery. Review of the literature highlights pertinent risk factors and demonstrates nearly one-third of reported cases have an iatrogenic etiology. The cases presented here demonstrate that a subdural process should be suspected in any patient with intractable pain following treatment of an epidural abscess. PMID:27402228

    To evaluate macular thickness in eyes with mild nonproliferative diabetic retinopathy (NPDR), patients with diabetes type 2, NPDR level 20 or 35, and without evidence of clinical macular edema underwent best-corrected visual acuity assessment, color fundus photography and Stratus optical coherence tomography. Mean center point thickness (CPT) and mean central subfield (CSF) thickness were compared with those of a healthy control population. 410 eyes/patients aged 61.2 ± 8.3 years, and with glycosylated hemoglobin of 7.9 ± 1.5% were included. Mean CPT and CSF were 186.6 ± 28.4 and 215.2 ± 25 µm, respectively, significantly increased compared to healthy subjects (p < 0.001). CSF thickness was abnormally increased in 17.6% of the patients, with values within the normal range in 79.5%, and abnormally decreased in 2.9%. CPT and CSF thickness were significantly thicker in men. No systemic factors showed a significant association. A significant increase in the macular thickness was found in eyes/patients with mild NPDR without clinical macular edema; however, only 17.6% of the eyes/patients had abnormally increased values and less than 3% abnormally decreased values.

    Leptospirosis and haemorrhagic fever with renal syndrome (HFRS) are hard to distinguish clinically since these two important rodent-borne zoonoses share hallmark symptoms such as renal failure and haemorrhage. Leptospirosis is caused by infection with a spirochete while HFRS is the result of an infection with certain hantaviruses. Both diseases are relatively rare in the Netherlands. Increased incidence of HFRS has been observed since 2007 in countries that border the Netherlands. Since a similar rise in incidence has not been registered in the Netherlands, we hypothesise that due to overlapping clinical manifestations, hantavirus infections may be confused with leptospirosis, leading to underdiagnosis. Therefore, we tested a cohort of non-travelling Dutch patients with symptoms compatible with leptospirosis, but with a negative diagnosis, during 2010 and from April to November 2011. Sera were screened with pan-hantavirus IgG and IgM enzyme-linked immunosorbent assays (ELISAs). Sera with IgM reactivity were tested by immunofluorescence assay (IFA). ELISA (IgM positive) and IFA results were confirmed using focus reduction neutralisation tests (FRNTs). We found hantavirus-specific IgG and/or IgM antibodies in 4.3% (11/255) of samples taken in 2010 and in 4.1% (6/146) of the samples during the 2011 period. After FRNT confirmation, seven patients were classed as having acute Puumala virus infections. A review of hantavirus diagnostic requests revealed that at least three of the seven confirmed acute cases as well as seven probable acute cases of hantavirus infection were missed in the Netherlands during the study period.

    Symptomatic intracavernous aneurysm is rare. Cranial nerves in the cavernous sinus are subjected to the mass effect of an expanding aneurysm. Microsurgical clipping is the treatment of choice to relieve compressive cranial neuropathy. In this video, the authors present a case of intracavernous aneurysm causing diplopia, ptosis, and facial numbness. The patient was operated on via a pretemporal transclinoid-transcavernous approach. The aneurysm was completely obliterated through direct clipping. There were no new-onset neurologic deficits and complications after the operation. Complete recovery of the diplopia, ptosis, and facial numbness was observed at the 6-month postoperative follow up. The video can be found here: http://youtu.be/4w5QUoNIAQM. PMID:26132609

She had had two episodes of esophageal variceal bleeding, successfully treated by endoscopic banding. and an episode of acute cholangitis secondary to portal cavernoma cholangiopathy. Endoscopic sphincterotomy and biliary stenting were performed, and were followed by repeated episodes of biliary stent occlusion. The last biliary drainage procedure triggered a massive hemobilia. Since endoscopic therapy was ineffective, a surgical mesocaval shunt with graft interposition and splenectomy was performed with favorable outcome. In selected cases, the mesocaval shunting plays an essential role in the treatment of portal cavernoma cholangiopathy even in the era of interventional radiology. PMID:27689206

    Neurologic involvement is well recognized in Systemic Scleroderma and increasingly reported in Localized Scleroderma. MRI brain abnormalities are often associated with symptoms such as seizures or headaches. In some cases they may be clinically silent. We describe a 23 years old female with head, trunk and limbs scleroderma who developed Parry-Romberg Syndrome. Brain MRI showed ipsilateral temporal lobe atrophy without any prominent neurologic symptoms. Neuropsychological examination revealed Mild Cognitive Impairment. During the 7 years of follow up we have noticed progression of face atrophy but no progression of brain atrophy. Cognitive functions have been stable. This case highlight that major MRI brain abnormalities in LS may occur with only subtle clinical manifestation such as Mild Cognitive Impairment.

    Background Heterogeneous bleeding phenotypes are observed in haemophilia A patients with the same mutation in the F8 gene. Specific mutations in the A2 domain of factor VIII are associated with mild haemophilia and a higher risk of inhibitor development. Double mutations in mild haemophilia A are rarely reported. In this study, we investigated the in vitro function of factor VIII, performing different specific and global coagulation assays, observed clinical characteristics and assessed the possible predictive diagnostic value of the differences. Materials and methods The clinical features of haemophiliacs with a mild phenotype were reviewed. Blood samples were obtained and analysed for mutations and coagulation assays: activated partial thromboplastin time, one-stage and chromogenic factor VIII activity, factor VIII antigen and rotational thromboelastometry. Results We report on a cohort of 22 patients with double Glu113Asp, Arg593Cys mutations. All our patients have a quantitative defect of factor VIII and preserved similar functional activity. Factor VIII activities measured by the one-stage or chromogenic method were not discrepant, although the chromogenic assay resulted in 20% lower factor VIII activities. Waveform analysis showed a lower maximum value of the second derivative curve (Max2) of APTT with curve shape alternation, while thromboelastometry (INTEM) showed low sensitivity in comparison to results in a normal population. Discussion In genotyping, the coexistence of a second mutation should never be excluded, especially in cases of discordant clinical presentation. Waveform analysis correlates better with factor VIII activity than thromboelastometry and the Max2 parameter could provide additional information in managing haemophilia patients. The utility of specific factor activity and global haemostatic assays in general practice still needs to be investigated. PMID:26057490

    The comparative long-term antianginal efficacy of long-acting nitrates versus calcium channel antagonists remains unclear. The goal of the present study was to compare the coronary endothelial cell function and coronary artery vasoconstriction between patients with normal or mildly diseased coronary arteries treated with long-acting nitrates or calcium channel antagonists. Forty-two patients suspected to have angina pectoris and with normal or mildly diseased coronary arteries underwent Doppler flow study of the left anterior descending coronary artery. All patients were suspected to have angina pectoris and were receiving either long-acting nitrates (n = 18; Nitrates group) or calcium channel antagonists (n = 24; Ca-antagonists group) for at least 1 year. Vascular reactivity was assessed by intracoronary administration of papaverine, acetylcholine (Ach), and nitroglycerin using a Doppler guidewire. Segments that showed the greatest constrictive response to Ach were used for assessment of vasoconstriction. The percent increase in coronary blood flow (CBF) and coronary artery diameter (CAD) induced by Ach was significantly smaller in the Nitrates group than in the Ca-antagonists group (33% +/- 74% vs 83% +/- 77%, P < 0.05; -3% +/- 16% vs 11% +/- 12%, P < 0.01, respectively). The percent diameter reduction in the region of greatest constrictive response to Ach was significantly greater in the Nitrates group than in the Ca-antagonists group (44% +/- 39% vs 15% +/- 32%, P < 0.02). Long-term treatment with long-acting nitrates may produce less favorable effects on coronary endothelial function and the constrictive response to Ach when compared with long-acting calcium channel antagonists in patients with normal or mildly diseased coronary arteries.

    Lepidium meyenii (Maca) is a cultivated root belonging to the brassica family used in the Andean region for its supposed aphrodisiac properties. We carried out a double-blind clinical trial on 50 Caucasian men affected by mild erectile dysfunction (ED), randomised to treatment with Maca dry extract, 2400 mg, or placebo. The treatment effect on ED and subjective well-being was tested administrating before and after 12 weeks the International Index of Erectile Function (IIEF-5) and the Satisfaction Profile (SAT-P). After 12 weeks of treatment, both Maca- and placebo-treated patients experienced a significant increase in IIEF-5 score (P < 0.05 for both). However, patients taking Maca experienced a more significant increase than those taking placebo (1.6 +/- 1.1 versus 0.5 +/- 0.6, P < 0.001). Both Maca- and placebo-treated subjects experienced a significant improvement in psychological performance-related SAT-P score, but the Maca group higher than that of placebo group (+9 +/- 6 versus +6 +/- 5, P < 0.05). However, only Maca-treated patients experienced a significant improvement in physical and social performance-related SAT-P score compared with the baseline (+7 +/- 6 and +7 +/- 6, both P < 0.05). In conclusion, our data support a small but significant effect of Maca supplementation on subjective perception of general and sexual well-being in adult patients with mild ED. PMID:19260845

    Recent findings have implicated the gut microbiota as a contributor of metabolic diseases through the modulation of host metabolism and inflammation. Atherosclerosis is associated with lipid accumulation and inflammation in the arterial wall, and bacteria have been suggested as a causative agent of this disease. Here we use shotgun sequencing of the gut metagenome to demonstrate that the genus Collinsella was enriched in patients with symptomatic atherosclerosis, defined as stenotic atherosclerotic plaques in the carotid artery leading to cerebrovascular events, whereas Roseburia and Eubacterium were enriched in healthy controls. Further characterization of the functional capacity of the metagenomes revealed that patient gut metagenomes were enriched in genes encoding peptidoglycan synthesis and depleted in phytoene dehydrogenase; patients also had reduced serum levels of β-carotene. Our findings suggest that the gut metagenome is associated with the inflammatory status of the host and patients with symptomatic atherosclerosis harbor characteristic changes in the gut metagenome.

    Nowadays oral appliance therapy is recognised as an effective therapy for many patients with primary snoring and mild to moderate obstructive sleep apnoea (OSA), as well as those with more severe OSA who cannot tolerate positive airway pressure (PAP) therapies. For this reason, it is important to focus on objective criteria to indicate which subjects may benefit from treatment with a mandibular advancement device (MAD). Various anthropometric and polysomnographic predictors have been described in the literature, whereas there are still controversies about the role of drug-induced sleep endoscopy (DISE) and advancement bimanual manoeuvre as predictor factors of treatment outcome by oral device. Herein, we report our experience in treatment of mild moderate OSA by oral appliance selected by DISE. We performed a single institution, longitudinal prospective evaluation of a consecutive group of mild moderate patients with obstructive sleep apnoea syndrome who underwent DISE. During sleep endoscopy, gentle manoeuvre of mandibular advancement less than 5 mm was performed. In 30 of 65 patients (46.2%) we obtained an unsuccessful improvement of airway patency whereas in 35 of 65 patients (53.8%) the improvement was successful and patients were considered suitable for oral device application. Because 7 of 35 patients were excluded due to conditions interfering with oral appliance therapy, we finally treated 28 patients. After 3 months of treatment, we observed a significant improvement in the Epworth medium index [(7.35 ± 2.8 versus 4.1 ± 2.2 (p < 0.05)], in mean AHI [(21.4 ± 6 events per hour versus 8.85 ± 6.9 (p < 0.05)] and in mean ODI [(18.6 ± 8 events per hour to 7 ± 5.8 (p < 0.05)]. We observed that the apnoea/hypopnoea index (AHI) improved by up to 50% from baseline in 71.4% of patients selected after DISE for MAD therapy. In the current study, mandibular advancement splint therapy was successfully prescribed on the basis not only of severity of disease, as

    Background S-adenosyl-L-methionine (SAMe), a safe, endogenous, pleiotropic methyl donor well known for its antidepressant role, has been assumed to have a possible role in increasing plasma levels of compounds known to be able to raise cardiovascular risk. Although the issue is still being debated, betaine (trimethylglycine), a specific methyl donor involved in the homocysteine circuit, may be able to reduce such a risk and/or, by determining a sparing effect on endogenous SAMe, may be able to improve the clinical efficiency of SAMe itself. Indeed, preliminary results have shown clinical improvement determined by an add-on therapy with betaine administered along with SAMe, versus SAMe alone, to patients affected by mild/moderate depression. Aim To evaluate the safety and antidepressant role played by the association of SAMe plus betaine versus amitriptyline administered in untreated individuals with a recent diagnosis of mild depression. Methods This small, open-label, randomized, observational study enrolled 64 individuals with a diagnosis of mild depression according to the Zung Self-Rating Depression Scale. After randomization, they were treated with either Laroxyl® (amitriptyline, 75 mg/day) or DDM Metile® (enteric-coated SAMe, 500 mg/day, plus betaine, 250 mg/day) for 12 months. Assessment of clinical scores and tolerability was performed at T=0 and after 3, 6, and 12 months. Results After 3 months, both treatments showed a small and not statistically significant improvement. After 6 and 12 months, both treated groups demonstrated a more noticeable improved response, although the group treated with SAMe plus betaine showed better results in terms of score, number of individuals in remission, and side effects. Compliance was overlapping in both treatments. Conclusion The association of SAMe plus betaine seems to be a safe and effective tool to counteract mild depression and also when used as monotherapy in subjects with a recent diagnosis.

    This report describes a patient with symptomatic Trichomonas vaginalis infection who was unable to tolerate nitroimidazole drugs because of severe hypersensitivity, for which desensitisation was not possible. Use of intravaginal clotrimazole, intravaginal paromomycin, intravaginal furazolidone, povidone-iodine douches, and oral nitazoxanide were unsuccessful in eradicating the patient's T. vaginalis infection. A 2-month course of intravaginal topical boric acid subsequently achieved a complete symptomatic cure and the patient remained T. vaginalis wet prep- and culture-negative 60 days after treatment.

    Oxidative stress associated with increased presence of neutrophils is an important feature of inflammatory airways diseases like asthma or chronic obstructive pulmonary disease. We studied the in vitro effect of piclamilast (RP73401), a selective phosphodiesterase (PDE)-4 inhibitor, compared to theophylline and prednisolone, on respiratory burst of sputum cells from mild asthmatics and COPD patients. Sputum cells were harvested from mild asthmatics and stable COPD patients and treated with piclamilast, theophylline or prednisolone. Respiratory burst was assessed by luminol-dependent chemoluminescence after stimulation with 10 microM n-formyl-met-leu-phe (FMLP). Piclamilast inhibited FMLP-induced respiratory burst of sputum cells in a concentration-dependent manner (asthma: EC50 approximately 100 nM, max. inhibition: 97.5+/-5% at 100 microM; COPD: EC50 approximately 1 microM, max. inhibition: 70.6+/-4.5% at 100 microM), whereas maximal inhibition observed with theophylline (asthma: max. inhib. 27+/-15%; COPD: 6+/-2%, both p < 0.05 vs. piclamilast) and prednisolone (asthma: 16+/-6%; COPD: 7.8+/-6.2%, both p < 0.05 vs. piclamilast) was weaker. Inhibition by piclamilast was largely reversed through pretreatment of cells with the adenylcyclase inhibitor SQ22536. We concluded that piclamilast, a selective PDE-4 inhibitor, attenuates the respiratory burst of sputum cells from mild asthmatics and COPD patients in vitro. These data underline the potential of PDE-4 inhibition as a novel therapeutic approach to inflammatory airway diseases like asthma or COPD.

    Objective: At present, inhibition of cholines-terase is the treatment of choice for subjects with mild-to-moderate Alzheimer's disease (AD). Memantine, a noncompetitive antagonist at N-methyl-d-aspartate receptors, is currently used to treat subjects with moderate-to-severe AD. The goal of this multicenter, open-label pilot study was to investigate whether combination therapy with memantine added to rivastigmine is safe and beneficial in subjects with mild-to-moderate AD. Method: Patients with a DSM-IV diagnosis of dementia of the Alzheimer's type (N = 95), who were treated with rivastigmine (6–12 mg/day) for a maximum duration of 24 weeks prior to baseline, received memantine (5–20 mg/day) in combination with rivastigmine for 12 weeks. The primary efficacy variable was the change in the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) total score at the end of 12 weeks compared with baseline. The study was conducted between September 15, 2003, and May 27, 2004. Results: There was a statistically significant difference between baseline and week 12 for the ADAS-cog total score, showing a positive effect of combination therapy. Combination therapy did not evidence any unexpected safety concerns and was well-tolerated by most patients. Conclusion: Memantine in combination with rivastigmine appears to be safe and beneficial in patients with mild-to-moderate AD. Our results need to be confirmed in a large, long-term, randomized, double-blind, placebo-controlled clinical trial. PMID:17235381

    The objective of this study was to assess the effects of subcutaneous (sc) interferon beta-1a (IFNbeta-1a) on cognition in mildly disabled patients with relapsing-remitting multiple sclerosis (RRMS). Patients aged 18-50 years with RRMS (McDonald criteria; Expanded Disability Status Scale score patients who received sc IFNbeta-1a (44 mcg: n = 236; 22 mcg: n = 223; three-year follow up was available for 318 patients). The hazard ratio for cognitive impairment over three years (44 mcg versus 22 mcg) was 0.68 (95% confidence interval [CI]: 0.480-0.972), suggesting a 32% lower risk with the higher dose treatment. At year 3, the proportion of patients who were cognitively impaired increased slightly from 23.5% at the baseline to 24.8% in the IFNbeta-1a 22 mcg treatment group, but remained stable at 15.2% in the IFNbeta-1a 44 mcg treatment group. The proportion of patients with cognitive impairment at year 3 was significantly higher in the 22 mcg group than in the 44 mcg group (P = 0.03), although a trend was also seen at the baseline (P = 0.058). Multivariate logistic regression (corrected for baseline cognitive deficits) indicated that treatment with the higher dose of IFNbeta-1a was predictive of lower cognitive impairment at three years (odds ratio: 0.51, 95% CI: 0.26-0.99) compared with the lower dose of IFNbeta-1a. These findings suggest that sc IFNbeta-1a may have dose-dependent cognitive benefits in mildly disabled patients with RRMS, and may support early initiation of high-dose IFNbeta-1a treatment.

    Fever is a common symptom in cancer patients. The most frequent causes of fever are infections, malignancy itself, various medications, transfusions, and allergy. Although it is necessary to treat the cause of fever, if possible, symptomatic fever management is also important. Surprisingly, little attention is paid to this topic in the medical literature, despite the fact that it is a very frequent problem. In order to support symptomatic fever therapy, we wanted to study the patients' discomfort accompanying fever and the beneficial effects of the symptomatic fever management. To the best of our knowledge, there is an absence of studies in this area, despite the fever discomfort can be an important reason for the antipyretic treatment, mainly in cancer patients. In this non-randomized open label pilot study, three intravenous antipyretics were tested in five groups of patients: diclofenac (75 mg, brief intravenous [IV] infusion) vs. metamizol (2500 mg or 1000 mg, brief IV infusion) vs. propacetamol (2000 mg or 1000 mg, slow IV injection or brief IV infusion). The study included 254 febrile episodes mainly in hemato-oncological patients with axillary temperature at least 38 degrees C. The main study endpoints were: changes in axillary temperature, improvement in patient comfort, and number and nature of adverse events. To support justification for symptomatic fever management in febrile patients, we asked the first 45 study subjects to fill in a questionnaire concerning their opinions about fever, fever-associated discomfort, and relief upon antipyretic therapy. All study medications had a significant antipyretic effect. However, metamizol at the dose 2500 mg was considered as the most effective, while propacetamol at the dose 1000 mg showed the lowest antipyretic efficacy. Concerning tolerability and adverse events, there were significant differences among the treatment groups. Diclofenac and metamizol (both 2500 mg and 1000 mg) were tolerated at best. All tested

    In a recent study, analyzing the modulation of γ-band oscillations, Naro and colleagues demonstrated that transcranial alternating current stimulation could drive the gamma rhythms in the human EEG in cognitive healthy elderly subjects but not in mild cognitive impairment (MCI) prodromal to Alzheimer's disease (AD) and in early AD patients. Therefore, this method is proposed to intercept early in the disease course those MCI subjects who are in a pre-symptomatic stage of an already established AD. This prediction index may help the clinician to adopt a better prevention/follow-up strategy. In this direction, the novel advances in EEG analysis for the evaluation of brain reactivity and connectivity-namely via innovative mathematical approach, i.e., graph theory-represent a promising tool for a non-invasive and easy-to-perform neurophysiological marker that could be used for the pre-symptomatic diagnosis of AD and to predict MCI progression to dementia.

    Background Several studies of moderate-to-severe depression have shown that combined treatment with individual cognitive behavioral therapy (CBT) and antidepressant medication is better than either CBT or antidepressants alone. Less research has focused on the outcomes of group-CBT and antidepressants in persons with mild depression. Aim Evaluate the effects of group-CBT in combination with antidepressants on the quality of life and social functioning of outpatients with mild depression. Methods We randomized 62 outpatients with mild depression into a control group (n=30) that received antidepressant medication for 12 weeks and an intervention group (n=32) that received antidepressants and group-CBT for 12 weeks; both groups were then continued on antidepressants alone for one year. Blinded evaluators used Chinese versions of the Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Social Disability Screening Schedule, Life Satisfaction Rating, Multidimensional Scale of Perceived Social Support, and Short Form Health Survey to assess participants after 12 weeks of treatment and at the end of one year of follow-up. Results Repeated measures analysis of variance showed that the depressive and anxiety symptoms of both groups improved significantly during treatment and that the improvement was greater in the CBT+antidepressant experimental group. Almost all of the social functioning, social support, and quality of life measures also showed significantly greater improvement in the CBT+antidepressant group than in the antidepressant-only group. Moreover, even after adjusting for differences in baseline demographic and clinical characteristics and for changes in the severity of depression and anxiety over time using an analysis of covariance, the greater improvement in the CBT+antidepressant group remained statistically significant both after the 12 weeks of group-CBT treatment and one year after the group CBT had ended.

    Introduction. Many patients with mild/moderate traumatic brain injury (m/mTBI) in the chronic stage suffer from executive brain function impairment. Analyzing brain metabolism is important for elucidating the pathological mechanisms associated with their symptoms. This study aimed to determine the differences in brain glucose metabolism between m/mTBI patients with and without visible traumatic brain lesions based on MRI. Methods. Ninety patients with chronic m/mTBI due to traffic accidents were enrolled and divided into two groups based on their MRI findings. Group A comprised 50 patients with visible lesions. Group B comprised 40 patients without visible lesions. Patients underwent FDG-PET scans following cognitive tests. FDG-PET images were analyzed using voxel-by-voxel univariate statistical tests. Results. There were no significant differences in the cognitive tests between Group A and Group B. Based on FDG-PET findings, brain metabolism significantly decreased in the orbital gyrus, cingulate gyrus, and medial thalamus but increased in the parietal and occipital convexity in Group A compared with that in the control. Compared with the control, patients in Group B exhibited no significant changes. Conclusions. These results suggest that different pathological mechanisms may underlie cognitive impairment in m/mTBI patients with and without organic brain damage. PMID:27529067

    Patients with underlying renal disease may be vulnerable to vancomycin-mediated nephrotoxicity and Staphylococcus aureus bacteremia treatment failure. In light of recent data demonstrating the successful use of β-lactam plus daptomycin in very difficult cases of S. aureus bacteremia, we examined safety and clinical outcomes for patients who received daptomycin with or without concomitant β-lactams. We identified 106 patients who received daptomycin for S. aureus bacteremia, had mild or moderate renal insufficiency according to FDA criteria, and enrolled in the Cubicin Outcomes Registry and Experience (CORE), a multicenter registry, from 2005 to 2009. Daptomycin treatment success was 81%. Overall treatment efficacy was slightly enhanced with the addition of a β-lactam (87% versus 78%; P = 0.336), but this trend was most pronounced for bacteremia associated with endocarditis or bone/joint infection or bacteremia from an unknown source (90% versus 57%; P = 0.061). Factors associated with reduced daptomycin efficacy (by logistic regression) were an unknown source of bacteremia (odds ratio [OR] = 7.59; 95% confidence interval [CI] = 1.55 to 37.2), moderate renal impairment (OR = 9.11; 95% CI = 1.46 to 56.8), and prior vancomycin failure (OR = 11.2; 95% CI = 1.95 to 64.5). Two patients experienced an increase in creatine phosphokinase (CPK) that resolved after stopping daptomycin. No patients developed worsening renal insufficiency related to daptomycin. In conclusion, daptomycin appeared to be effective and well tolerated in patients with S. aureus bacteremia and mild to moderate renal insufficiency. Daptomycin treatment efficacy might be enhanced with β-lactam combination therapy in primary endovascular and bone/joint infections. Additional studies will be necessary to confirm these findings.

    Hyperlipidemia can lead to atherosclerosis by lipoprotein deposition inside the vessel wall and oxidative stress induction that leads to the formation of atherosclerotic plaque. Oxidized low-density lipoprotein particles (Ox-LDL) have a key role in the pathogenesis of atherosclerosis. The lipid-lowering properties and antioxidants of the grape seed can be beneficial in atherosclerosis prevention. We conducted a randomized double-blind placebo-controlled crossover clinical trial. Fifty-two mildly hyperlipidemic individuals were divided into two groups that received either 200 mg/day of the red grape seed extract (RGSE) or placebo for 8 weeks. After an 8-week washout period, the groups were crossed over for another 8 weeks. Lipid profiles and Ox-LDL were measured at the beginning and the end of each phase. RGSE consumption reduced total cholesterol (-10.68±26.76 mg/dL, P=.015), LDL cholesterol (-9.66±23.92 mg/dL, P=.014), and Ox-LDL (-5.47±12.12 mg/dL, P=.008). While triglyceride and very low-density lipoprotein cholesterol were decreased and high-density lipoprotein cholesterol was increased by RGSE, the changes were not statistically significant. RGSE consumption decreases Ox-LDL and has beneficial effects on lipid profile-consequently decreasing the risk of atherosclerosis and cardiovascular disorders-in mild hyperlipidemic individuals.

    Smoking is a major risk factor for several diseases including chronic obstructive pulmonary disease (COPD). To better understand the systemic effects of cigarette smoke exposure and mild to moderate COPD—and to support future biomarker development—we profiled the serum lipidomes of healthy smokers, smokers with mild to moderate COPD (GOLD stages 1 and 2), former smokers, and never-smokers (n = 40 per group) (ClinicalTrials.gov registration: NCT01780298). Serum lipidome profiling was conducted with untargeted and targeted mass spectrometry-based lipidomics. Guided by weighted lipid co-expression network analysis, we identified three main trends comparing smokers, especially those with COPD, with non-smokers: a general increase in glycero(phospho)lipids, including triglycerols; changes in fatty acid desaturation (decrease in ω-3 polyunsaturated fatty acids, and an increase in monounsaturated fatty acids); and an imbalance in eicosanoids (increase in 11,12- and 14,15-DHETs (dihydroxyeicosatrienoic acids), and a decrease in 9- and 13-HODEs (hydroxyoctadecadienoic acids)). The lipidome profiles supported classification of study subjects as smokers or non-smokers, but were not sufficient to distinguish between smokers with and without COPD. Overall, our study yielded further insights into the complex interplay between smoke exposure, lung disease, and systemic alterations in serum lipid profiles. PMID:27657052

    We aimed to review the results of subtotal arthroscopic resection of symptomatic type D medial plica. We retrospectively evaluated 23 knees with symptomatic type D medial plica in 22 patients without other intra-articular pathology. All patients complained of chronic knee pain that had not been alleviated by medical treatment or physical therapy. In only three (13%) of the patients studied was the plica diagnosed pre-operatively with magnetic resonance imaging. The type D medial plicae in our series were classified as fenestrated (14 knees), torn (5 knees), or reduplicated (4 knees). Fibrotic changes in the plicae and degenerative changes on the medial femoral condyle were found in 16 knees Patellofemoral chondromalacia was present in three knees Arthroscopic partial resection was performed in all patients. Comparative Lysholm Knee Scale scores before and after surgery revealed a significant clinical improvement (pre-operative status, 67.19 +/- 8.05 vs. post-operative status, 90.57 +/- 9.80; P < 0.001). Type D medial plica should be considered as a possible cause of chronic knee pain. Arthroscopic partial resection of the plicae in symptomatic patients gives satisfactory results.

    Attentional selection, i.e. filtering out of irrelevant sensory input and information storage are two crucial components of working memory (WM). It has been proposed that the two processes are mediated by different neurotransmitters, namely acetylcholine for attentional selection and dopamine for memory storage. However, this hypothesis has been challenged by others, who for example linked a lack in dopamine levels in the brain to filtering deficits. Here we tested the above mentioned hypothesis in two patient cohorts which either served as a proxy for a cholinergic or a dopaminergic deficit. The first group comprised 18 patients with amnestic mild cognitive impairment (aMCI), the second 22 patients with Parkinson׳s disease (PD). The two groups did not differ regarding their overall cognitive abilities. Both patient groups as well as a control group without neurological deficits (n=25) performed a visuo-spatial working memory task in which both the necessity to filter out irrelevant information and memory load, i.e. the number of items to be held in memory, were manipulated. In accordance with the primary hypothesis, aMCI patients displayed problems with filtering, i.e., were especially impaired when the task required ignoring distracting stimuli. PD patients on the other hand showed difficulties when memory load was increased suggesting that they mainly suffered from a storage deficit. In sum, this study underlines how the investigation of neurologic patients with a presumed neurotransmitter deficit can aid to clarify these neurotransmitters׳ contribution to specific cognitive functions.

    A four-year longitudinal cohort and geographic cluster study in rural Thailand was conducted to characterize the clinical spectrum of dengue virus (DENV) infection. Symptomatic DENV infections in the cohort were detected by active school absence-based surveillance that triggered cluster investigations around ill cohort children. Data from 189 cohort children with symptomatic DENV infection and 126 contact children in the clusters with DENV infection were analyzed. Of infected contacts, only 19% were asymptomatic; 81% were symptomatic, but only 65.9% reported fever. Symptom-based case definitions were unreliable for diagnosis. Symptomatic infections in contacts were milder with lower DENV RNA levels than the cohort. Infections in contacts with fever history were more likely to have detectable DENV RNA than infections without fever history. Mild infections identified by cluster investigations account for a major proportion of all DENV infections. These findings are relevant for disease burden assessments, transmission modeling, and determination of vaccine impact.

    Pancreas divisum (PD) is the most common congenital variant of the pancreas and has been implicated as a cause of pancreatitis; however, endoscopic treatment is controversial. Our objective was to examine patient response to endotherapy for treatment of symptomatic PD in adult patients in a systematic review of the literature. A systematic review of all case series and case-control studies with ten or more patients undergoing endotherapy for treatment of symptomatic PD indicated by acute recurrent pancreatitis (ARP), chronic pancreatitis (CP), or chronic abdominal pain (CAP) was performed. PubMed, Embase, and Web of Science databases were searched from inception through February 2013 using [pancreas divisum] AND [endoscopic retrograde cholangiopancreatography (ERCP)] OR [endotherapy] OR [endoscopy] as search terms. Importantly, the majority of studies were retrospective in nature, significantly limiting analysis capacity. Main outcomes measures included endotherapy response rate in patients with PD and ARP, CP, or CAP. Twenty-two studies were included in the review, with a total of 838 patients. Response to endoscopy was seen in 528 patients, but response rate varied by clinical presentation. Patients with ARP had a response rate ranging from 43% to 100% (median 76%). Reported response rates were lower in the other two groups, ranging from 21% to 80% (median 42%) for patients with CP and 11%-55% (median 33%) for patients with CAP. Complications reported included perforation, post-endoscopic retrograde cholangiopancreatography pancreatitis, bleeding, and clogged stents. Endotherapy appears to offer an effective treatment option for patients with symptomatic PD, with the best results in patients presenting with ARP.

    Opinion varies on whether or not hepatitis C virus (HCV) infected patients with persistently normal aminotransferase (PNALT) levels represent a group with mild disease. To evaluate the risk of ALT flare and fibrosis progression in patients with PNALT followed up as part of the Trent HCV cohort. Treatment-naïve patients with an elevated ALT (n = 1140) or PNALT, the latter defined as either an ALT < or = 30 IU/L (n = 43) or an ALT < or = 40 IU/L (n = 87) on > or =2 occasions in the 6 months following diagnosis, and no ALT > 40 U/L were included. The likelihood of maintaining a PNALT < or = 30 IU/L was 42.2% and PNALT < or = 40 IU/L 41.7% at 3 years. The Ishak fibrosis score was > or =3 in 3.7%, 8.3% and 29.6% of patients with PNALT < or = 30 IU/L, PNALT < or = 40 IU/L and elevated ALT, respectively. Fibrosis progression between paired biopsies was similar for patients with PNALT < or = 30 IU/L (0.33 +/- 0.94 Ishak fibrosis points/year), PNALT < or = 40 IU/L (0.35 +/- 0.82) and elevated ALT (0.19 +/- 0.48). The majority of those defined as PNALT subsequently have an abnormal ALT. They have a similar risk of disease progression to other HCV infected patients and, therefore, warrant the same consideration with regard to treatment. PMID:19656289

    Type 2 diabetes mellitus is a metabolic disorder and a risk factor for dementia and mild cognitive impairment (MCI), which could also increase the risk of progression from MCI to dementia. The present study evaluated the spontaneous neuronal activity of 31 patients with MCI using resting-state functional MRI. The patients were divided into two groups (17 MCI patients without diabetes, and 14 patients with type 2 diabetes who were considered as the MCI-DM group) and 17 well-matched healthy controls were also recruited. The amplitude of low-frequency fluctuations (ALFF) of spontaneous blood oxygen level dependent signals was then applied to assess neuroimaging changes. To further investigate the impact of type 2 diabetes on cognition, the correlation of ALFF and the neuropsychological tests for the MCI-DM and MCI group were calculated. MCI-DM patients showed diffused ALFF changes in a variety of brain regions that were significantly related to cognitive performance, including the frontal lobe, the temporal lobe, the hippocampus, the amygdala, and the precuneus during a resting state; whereas, the alterations were much less pronounced in the MCI patients without diabetes. These findings provide new insights into understanding essential of diabetes mellitus and may help to clarify the relationship between diabetes mellitus and dementia.

    Summary The aim of this pilot randomized controlled trial was to evaluate the effects of treadmill training on cognitive and motor performance in patients with Parkinson’s disease (PD). Seventeen persons with mild to moderate PD were enrolled. Nine patients were allocated to the Intervention group and received twelve 45-minute sessions of treadmill training: one session a day, three days a week, for four consecutive weeks. Eight patients were allocated to the Control group; these patients did not undergo physical training but were required to have regular social interactions, following a specific lifestyle program. All the patients were evaluated at baseline and one month later. The primary outcome measures were the Frontal Assessment Battery-Italian version (FAB-it) and the 6-minute walking test (6MWT). At the one-month evaluation significant differences were found between the groups in their performance on the FAB-it (p=0.005) and the 6MWT (p=0.018). Our findings support the hypothesis that treadmill training might effectively improve cognitive and motor features in patients with PD. PMID:27027891

    Peripheral arterial disease (PAD) is associated with considerable morbidity and mortality. Consensus rightly demands the incorporation of supervised exercise training (SET) into PAD treatment protocols. However, the exact role of SET particularly its relationship with intervention requires further clarification. While supervised exercise is undoubtedly an excellent tool in the conservative management of mild PAD its use in more advanced disease as an adjunct to open or endovascular intervention is
