Canakinumab Relieves Symptoms of Acute Flares and Improves Health-Related Quality Of Life (HRQoL) in Difficult-To-Treat Gouty Arthritis Patients by Suppressing Inflammation: Results of a Randomized, Dose-Ranging Study

RATIONALE:We investigated the impact of canakinumab, a fully human anti-interleukin-1b monoclonal antibody on inflammation and HRQoL in gouty arthritis patients.METHODS: In this 8-week, single-blind, dose-ranging study, patients with acute gouty arthritis flares, unresponsive/intolerant or contraindicated to NSAIDs and/or colchicine were randomized to single subcutaneous canakinumab (10, 25, 50, 90, or 150mg, N5143) or single intramuscular triamcinolone acetonide (TA, 40mg, N557). Patients assessed pain (Likert scale), physicians assessed clinical signs of joint inflammation, and HRQoL was recorded using SF-36.RESULTS: At baseline, 98% patients had moderate-to-extreme pain, 85% had moderate/severe joint swelling, 64-79% had elevated inflammatory markers and HRQoL scores indicated impaired physical function. Percentage of patients with no/mild pain was numerically greater in most canakinumab groups vs. TA, 24-72h post-dose; difference significant for 150mg group at these time-points (P<0.05). Canakinumab 150mg was associated with significantly lower Likert scores for tenderness [OR, 3.2; 95% CI, 1.27-7.89; P50.014] and swelling (OR, 2.7; 95% CI, 1.09-6.50, P50.032) at 72h vs. TA; erythema was not different. Median CRP and SAA levels normalized by 7 days post-dose in most canakinumab groups, but remained elevated in TA. Physical function improved at 7 days postdose in all groups, highest improvement for canakinumab 150mg. SF-36 scores for physical functioning and bodily pain with canakinumab 150mg approached US general population scores by 7 days post-dose and exceeded normal values by 8 weeks post-dose.CONCLUSION: Canakinumab 150mg produced significantly greater and rapid pain-relief and improvements in HRQoL vs. TAin acute gouty arthritis patients.

An international validation study of the EORTC brain cancer module (EORTC QLQ-BN20) for assessing health-related quality of life and symptoms in brain cancer patients.

Aims: The psychometric properties of the EORTC QLQ-BN20, a brain cancer-specific HRQOL questionnaire, have been previously determined in an English-speaking sample of patients. This study examined the validity and reliability of the questionnaire in a multi-national, multi-lingual study. Methods: QLQ-BN20 data were selected from two completed phase III EORTC/NCIC clinical trials in brain cancer (N=891), including 12 languages. Experimental treatments were surgery followed by radiotherapy (RT) and adjuvant PCV chemotherapy or surgery followed by concomitant RT plus temozolomide (TMZ) chemotherapy and adjuvant TMZ chemotherapy. Standard treatment consisted of surgery and postoperative RT alone. The psychometrics of the QLQ-BN20 were examined by means of multi-trait scaling analyses, reliability estimation, known groups validity testing, and responsiveness analysis. Results: All QLQ-BN20 items correlated more strongly with their own scale (r>0.70) than with other QLQ-BN20 scales. Internal consistency reliability coefficients were high (all alpha0.70). Known-groups comparisons yielded positive results, with the QLQ-BN20 distinguishing between patients with differing levels of performance status and mental functioning. Responsiveness of the questionnaire to changes over time was acceptable. Conclusion: The QLQ-BN20 demonstrates adequate psychometric properties and can be recommended for use in conjunction with the QLQ-C30 in assessing the HRQOL of brain cancer patients in international studies.

Personality traits, behavioral and psychological symptoms and cognitive decline in patients at an early stage of Alzheimer's disease

The aim of this doctoral thesis was to study personality characteristics of patients at an early stage of Alzheimer's disease (AD), and more specifically to describe personality and its changes over time, and to explore its possible links with psychological and symptoms (BPS) and cognitive level. The results were compared to those of a group of participants without cognitive disorder through three empirical studies. In the first study, the findings showed significant personality changes that follow a specific trend in the clinical group. The profil of personality changes showed an increase in Neuroticism and a decrease in Extraversion, Openess to experiences, and Conscientiousness over time. The second study highlighted that personality and BPS occur early in the cours of AD. Recognizing them as possible precoce signs of neurodegeneration may prove to be a key factor for early detection and intervention. In the third study, a significant association between personality changes and cognitive status was observed in the patients with incipient AD. Thus, changes in Neuroticism and Conscientiousness were linked with cognitive deterioration, whereas decreased Openness to experiences and Conscientiousness over time predicted loss of independence in daily functioning. Other well-known factors such as age, education level or civil status were taken into account to predict cognitive decline. The three studies suggested five important implications: (1) cost-effective screening should take into account premorbid and specific personality changes; (2) psycho-educative interventions should provide information on the possible personality changes and BPS that may occur at the beginning of the disease; (3) using personality traits alongside other variables in the future studies on prevention might help to better understand AD's etiology; (4) individual treatment plans (psychotherapeutic, social, and pharmacological) might be adapted to the specific changes in personality profiles; (5) more researches are needed to study the impact of social-cultural and lifestyle variables on the development of AD.

Rifaximin treatment for the irritable bowel syndrome with a positive lactulose hydrogen breath test improves symptoms for at least 3 months.

BACKGROUND: While rifaximin was able to improve symptoms in patients with irritable bowel syndrome (IBS) in phase III trials, these results are yet to be repeated in phase IV studies. AIM: To evaluate the treatment response to rifaximin in IBS patients in a phase IV trial. METHODS: IBS patients underwent lactulose hydrogen breath testing (LHBT). LHBT-positive patients were treated with rifaximin for 14 days. Prior to treatment as well as at week 4 and 14 following the start of rifaximin treatment, patients completed a questionnaire assessing symptom severity on a Likert scale from 0 to 10. RESULTS: One hundred and six of 150 IBS patients (71%) were LHBT-positive and treated with rifaximin. As assessed at week 4 following commencement of the therapy, rifaximin provided significant improvement of the following IBS-associated symptoms: bloating (5.5±2.6 before the start of the treatment vs. 3.6±2.7 at week 4, P<0.001), flatulence (5.0±2.7 vs. 4.0±2.7, P=0.015), diarrhoea (2.9±2.4 vs. 2.0±2.4, P=0.005) and abdominal pain (4.8±2.7 vs. 3.3±2.5, P<0.001). Overall well-being also significantly improved (3.9 ± 2.4 vs. 2.7 ± 2.3, P < 0.001). Similar improvements in IBS symptoms were obtained at week 14. Eighty-six per cent of patients undergoing repetitive LHBT (55/64) tested negative at week 4. CONCLUSIONS: We found a high percentage of LHBT-positive IBS patients. IBS-associated symptoms (bloating, flatulence, diarrhoea, pain) were improved for a period of 3 months following 2 weeks of treatment with rifaximin. We conclude that rifaximin treatment alleviates symptoms in LHBT-positive IBS patients.

Family Alliance as a Moderator of the Link Between Maternal Postpartum Depression and Child Symptoms Assessed by Both Parents

We investigated the moderating effect of family relationships on the links between maternal postpartum depression and child symptoms in a low-risk community sample of families with 3-month-old infants (n = 57). The level of maternal depression was assessed by the Montgomery-Asberg Depression Rating Scale from a clinical interview, child symptoms by the Symptom Check List completed by both parents, and family relationships by direct observation of father-mother-baby interactions (Lausanne Trilogue Play). Families were categorized as high coordination or low coordination from their overall coordination level throughout the play. Results showed no significant links between maternal depression level and child symptoms reported by both parents. Mothers with a high depressive level in high coordination families tended to report more symptoms in their child than did mothers with lower depressive scores, whereas this link was not found in low coordination families. Prevention perspectives and clinical implications of these results are discussed.

Specificities of defense mechanisms in bipolar affective disorder: relations with symptoms and therapeutic alliance.

Defense mechanisms as a central notion of psychoanalysis have inspired various levels of interest in research in psychotherapy and psychopathology. Defense specificities have only recently been investigated systematically with regard to several clinical diagnoses, such as affective and personality disorders. For the present study, 30 inpatients diagnosed with Bipolar Affective Disorder I (BD) were interviewed. An observer-rater method, the Defense Mechanisms Rating Scales (DMRS), applied to session-transcripts, of assessment of defenses was used. A matched, nonclinical control group was introduced. Defense specificities in BD encompass a set of 5 immature defenses, of which omnipotence is linked with symptom level. The level of the therapeutic alliance is predicted by mature defenses. These results are discussed with regard to the psychological vulnerability of BD, and treatment implications for psychodynamic psychotherapy with such challenging patients are evoked.

Traumatic symptoms in sexually abused children : implications for school counselors

School counselors have a duty to formulate strategies that aid in the detection and prevention of child sexual abuse (American School Counselor Association, 2003). School counselors are charged with helping sexually abused children by recognizing sexual abuse indicators based on a child's symptomology and/or behavior, and understanding how this trauma may affect children in the school setting. Mandated reporting issues, talking with children and adolescents about sexual abuse suspicions, and understanding trauma symptoms and their contribution to the difficulties that sexually abused children have in school are highlighted. In addition, how school counselors can collaborate with clinicians treating sexually abused children through role-appropriate advocacy, intervention, and aftercare strategies is described.

Role of rhinovirus load in the upper respiratory tract and severity of symptoms in lung transplant recipients.

BACKGROUND: Rhinovirus is the most common cause of respiratory viral infections and leads to frequent respiratory symptoms in lung transplant recipients. However, it remains unknown whether the rhinovirus load correlates with the severity of symptoms. OBJECTIVES: This study aimed to better characterize the pathogenesis of rhinoviral infection and the way in which viral load correlates with symptoms. STUDY DESIGN: We assessed rhinovirus load in positive upper respiratory specimens of patients enrolled prospectively in a cohort of 116 lung transplant recipients. Rhinovirus load was quantified according to a validated in-house, real-time, reverse transcription polymerase chain reaction in pooled nasopharyngeal and pharyngeal swabs. Symptoms were recorded in a standardised case report form completed at each screening/routine follow-up visit, or during any emergency visit occurring during the 3-year study. RESULTS: Rhinovirus infections were very frequent, including in asymptomatic patients not seeking a specific medical consultation. Rhinovirus load ranged between 4.1 and 8.3 log copies/ml according to the type of visit and clinical presentation. Patients with highest symptom scores tended to have higher viral loads, particularly those presenting systemic symptoms. When considering symptoms individually, rhinovirus load was significantly higher in the presence of symptoms such as sore throat, fever, sputum production, cough, and fatigue. There was no association between tacrolimus levels and rhinovirus load. CONCLUSIONS: Rhinovirus infections are very frequent in lung transplant recipients and rhinoviral load in the upper respiratory tract is relatively high even in asymptomatic patients. Patients with the highest symptom scores tend to have a higher rhinovirus load.

Visual signs and symptoms in patients with the visual variant of Alzheimer disease.

BACKGROUND: Prominent visual symptoms can present in the visual variant of Alzheimer's disease (VVAD). Ophthalmologists have a significant role to play in the early diagnosis of VVAD. METHODS: We retrospectively reviewed the files of ten consecutive patients diagnosed with VVAD. All patients had a full neuro-ophthalmologic examination, a formal neurological and neuro-psychological testing, and cerebral MRI to confirm diagnosis. In addition, functional neuroimaging was obtained in seven patients. RESULTS: The common primary symptom at presentation with all patients was difficulty with near vision (reading difficulty n = 8, "visual blur" in near vision n = 2), and difficulty writing (n = 3). Following assessment, impaired reading and writing skills were evident in 9/10 and 8/10 patients respectively. Median distance visual acuity was 20/25 and at near the median visual acuity was J6. Partial homonymous visual field defect was detected in 80 % (8/10) of the patients. Color vision was impaired in all patients when tested with Ishihara pseudoisochromatic plates, but simple color naming was normal in 8/9 tested patients. Simultanagnosia was present in 8/10 patients. Vision dysfunction corresponded with cerebral MRI findings where parieto-occipital cortical atrophy was observed in all patients. PET scan (5 patients) or SPECT (2 patients) revealed parieto-occipital dysfunction (hypometabolism or hypoperfusion) in all 7 tested patients CONCLUSIONS: Visual difficulties are prominent in VVAD. Dyslexia, incomplete homonymous hemianopia, preserved color identification with abnormal color vision on Ishihara, and simultanagnosia were all symptoms observed frequently in this patient series. Ophthalmologists should be aware of the possibility of neurodegenerative disorders such as VVAD in patients with unexplained visual complaints, in particular reading difficulties.

L'hémodiayse intermittente, irremplaçable dans certains cas d'intoxications sévères [Intermittent hemodialysis, irreplaceable in specific cases of severe poisoning].

Le médecin praticien est souvent bien sensibilisé aux indications à l'hémodialyse au cours de l'insuffisance rénale sévère, que celle-ci soit aiguë ou chronique. En dehors des indications traditionnelles à une épuration extrarénale, il existe certaines situations comme des intoxications (metformine, éthylène glycol ou lithium) et d'autres conditions (hypercalcémie, lyse tumorale), dans lesquelles l'hémodialyse intermittente représente le traitement le plus efficace, voire le seul. Bien que ces situations demeurent peu fréquentes, il est décisif de les reconnaître rapidement The medical practitioner is in general well aware of the indications for hemodialysis in severe, acute or chronic renal insufficiency. Apart from the traditional indications for renal replacement therapy, there are some cases such as metfomin and ethylene glycol poisoning, lithium intoxication severe hypercalcemia and tumor lysis syndrome, in which intermittent hemodialysis is the most effective treatment, or sometimes the only effective one. Although these situations remain infrequent, it is crucial to recognize them as quickly as possible.

Posttraumatic stress avoidance symptoms as mediators in the development of alcohol use disorders after exposure to childhood sexual abuse in a Swiss community sample.

This study examined the role of posttraumatic stress disorder (PTSD) symptoms of re-experience, avoidance, and hyperarousal in the relationship between different types of trauma and alcohol use disorders (AUD). We used data from 731 trauma-exposed individuals who participated in the first wave of the PsyCoLaus-study. Trauma characteristics were assessed relatively to the occurrence of lifetime PTSD symptoms and AUD. The results suggest that lifetime and childhood sexual abuse as well as overall childhood trauma were directly linked to AUD and PTSD symptoms, in particular to avoidance symptoms. From single symptom clusters PTSD avoidance was found to specifically mediate the trauma-AUD pathway. Both childhood and sexual trauma strongly contribute to the comorbidity of PTSD and AUD and avoidance-type symptoms appear to play a central role in maintaining this association. Hence, the alleviation of avoidance symptoms might be an important target for therapeutic intervention among victims of sexual abuse before specific addiction treatment is initiated.

Radiographic volume analysis as a novel tool to determine nasopalatine duct cyst dimensions and its association with presenting symptoms and postoperative complications.

OBJECTIVES: The aims of the study were to use cone beam computed tomography (CBCT) images of nasopalatine duct cysts (NPDC) and to calculate the diameter, surface area, and 3D-volume using a custom-made software program. Furthermore, any associations of dimensions of NPDC with age, gender, presence/absence of maxillary incisors/canines (MI/MC), endodontic treatment of MI/MC, presenting symptoms, and postoperative complications were evaluated. MATERIAL AND METHODS: The study comprised 40 patients with a histopathologically confirmed NPDC. On preoperative CBCT scans, curves delineating the cystic borders were drawn in all planes and the widest diameter (in millimeter), surface area (in square millimeter), and volume (in cubic millimeter) were calculated. RESULTS: The overall mean cyst diameter was 15 mm (range 7-47 mm), the mean cyst surface area 566 mm(2) (84-4,516 mm(2)), and the mean cyst volume 1,735 mm(3) (65-25,350 mm(3)). For 22 randomly allocated cases, a second measurement resulted in a mean absolute aberration of ±4.2 % for the volume, ±2.8 % for the surface, and ±4.9 % for the diameter. A statistically significant association was found for the CBCT determined cyst measurements and the need for preoperative endodontic treatment to MI/MC and for postoperative complications. CONCLUSION: In the hands of a single experienced operator, the novel software exhibited high repeatability for measurements of cyst dimensions. Further studies are needed to assess the application of this tool for dimensional analysis of different jaw cysts and lesions including treatment planning. CLINICAL RELEVANCE: Accurate radiographic information of the bone volume lost (osteolysis) due to expansion of a cystic lesion in three dimensions could help in personalized treatment planning.

A qualitative study of adolescents with medically unexplained symptoms and their parents. Part 2: How is healthcare perceived?

Medically unexplained symptoms (MUS) are common among adolescents and an important cause of clinical visits. This study sought to understand the experiences with, and perceptions of, the healthcare of adolescents who have MUS and their parents. Using a qualitative approach, six focus groups and two individual interviews were conducted with a total of ten adolescents and sixteen parents. The participants were recruited in a university hospital in Switzerland. A thematic analysis was conducted in accordance with the Grounded Theory. Six main themes emerged: needing a label for the symptoms, seeking an etiology to explain the symptoms, negotiating the medical system, medication and treatments, interactions with doctors, and the inclusion of parents during consultations. Transcending these themes, however, was the need for good communication between the adolescents, their parents and the clinicians. When explaining the symptoms, clinicians should make sure to discuss the results, investigations and lack of organic origin.
