Project description:Trismus pseudocamptodactyly syndrome is a very rare autosomal dominant inherited disorder characterized by the inability to completely open the mouth (trismus) and the presence of abnormally short tendon units causing the fingers to curve (camptodactyly). Early diagnosis and management of this condition is important to prevent facial deformities in the patient. Reporting such a case is important as case reports are one of the sources of data for calculating the prevalence of rare diseases. Here, we report a case of trismus pseudocamptodactyly syndrome in an eight-year-old boy with a brief review of the literature.

Project description:OBJECTIVES:Voice handicap has generally been measured at a single timepoint. Little is known about its variability from hour to hour or day to day. Voice handicap has been shown to be negatively related to voice-related perceived control in cross-sectional studies, but the within-person variability in voice-related perceived control is also unknown. We aimed to use ecological momentary assessment (EMA) to (1) assess the feasibility of EMA to examine daily voice handicap and voice-related perceived control in patients with voice disorders, (2) measure within-person variability in daily voice handicap and perceived control, and (3) characterize temporal associations (eg, correlations over time) between daily voice handicap and perceived control. METHODS:Adults with voice problems were recruited from a large public university medical center in the Midwest. They completed baseline measures, followed by twice-daily assessments, including selected items measuring voice handicap and perceived control, and then repeated the baseline measures at the final timepoint. Feasibility was assessed via completion rates. Within-person variability was measured using standard deviations. Temporal associations were characterized using simulation modeling analysis. RESULTS:EMA of voice handicap and perceived control was feasible in this patient population. Momentary voice handicap varied more than perceived control, though both were variable. Multiple patterns of temporal associations between daily voice handicap and perceived control were found. CONCLUSIONS:These findings identified important variability in (1) measures of voice handicap and perceived control and (2) their associations over time. Future EMA studies in patients with voice disorders are both feasible and warranted.

Project description:Recently we proposed exploring the potential of treatment stimulated testing as diagnostic method for tuberculosis (TB). An infection controlled placebo controlled mouse study was performed to investigate whether serum cytokine levels changed measurably during the early phase of TB chemotherapy. Serum was collected prior to and during the first 3 weeks of isoniazid (INH) and rifampicin (RIF) chemotherapy, and levels of 23 selected cytokines/chemokines were measured using a liquid bead array. The serum levels of IFNγ, IP-10, MIG, MCP-1, IL-17 and IL-6 were elevated in the TB infected mice compared to non-infected mice at least at 1 time point measured. In infected mice, IFNγ, IP-10, MIG and MCP-1 levels decreased within 7 days of treatment with RIF+INH compared to placebo. Treatment of non-infected mice in the absence of tuberculosis infection had no effect on these cytokines. IL-17 and IL-6 had decreased to baseline in all infected mice prior to the initiation of treatment. This study demonstrates that systemic levels of some cytokines, more specifically IFNγ, IP-10, MIG and MCP-1, rapidly and specifically change upon starting TB chemotherapy only in the presence of infection in a mouse model. Thus, IFNγ, IP-10, MIG and MCP-1 are promising 'Treat-to-Test' targets for the diagnosis of TB and deserve further investigation in a study on human TB suspects.

Project description:BackgroundMixed M. tuberculosis (MTB) infection occurs when one is infected with more than one clonally distinct MTB strain. This form of infection can assist MTB strains to acquire additional mutations, facilitate the spread of drug-resistant strains, and boost the rate of treatment failure. Hence, the presence of mixed MTB infection could affect the performance of some rapid molecular diagnostic tests such as Line Probe Assay (LPA) and GeneXpert MTB/RIF (Xpert) assays.MethodsThis was a cross-sectional study that used sputum specimens collected from participants screened for STREAM 2 clinical trial between October 2017 and October 2019. Samples from 62 MTB smear-positive patients and rifampicin-resistant patients from peripheral health facilities were processed for Xpert and LPA as screening tests for eligibility in the trial. From November 2020, processed stored sputum samples were retrieved and genotyped to determine the presence of mixed-MTB strain infection using a standard 24-locus Mycobacterial Interspersed Repetitive Unit-Variable Number Tandem-Repeat (MIRU-VNTR). Samples with at least 20/24 MIRU-VNTR loci amplified were considered for analysis. Agar proportional Drug Susceptibility Test (DST) was performed on culture isolates of samples that had discordant results between LPA and Xpert. The impact of the presence of mixed-MTB strain on Xpert and LPA test interpretation was analyzed.ResultsA total of 53/62 (85%) samples had analyzable results from MIRU-VNTR. The overall prevalence of mixed-MTB infection was 5/53 (9.4%). The prevalence was highest among male's 3/31 (9.7%) and among middle-aged adults, 4/30 (33.3%). Lineage 4 of MTB contributed 3/5 (60.0%) of the mixed-MTB infection prevalence. Having mixed MTB strain infection increased the odds of false susceptible Xpert test results (OR 7.556, 95% CI 0.88-64.44) but not for LPA. Being HIV-positive (P = 0.04) independently predicted the presence of mixed MTB infection.ConclusionsThe presence of mixed-MTB strain infection may affect the performance of the GeneXpert test but not for LPA. For patients with high pre-test probability of rifampicin resistance, an alternative rapid method such as LPA should be considered.

Project description:BackgroundWe evaluated the effect of mixed-MTB strain infection on the performance of Line Probe Assay (LPA) and GeneXpert MTB/RIF (Xpert) assays among patients initiating MDR-TB treatment in Uganda.MethodsThis was a cross-sectional study using sputum specimens collected from participants screened for STREAM 2 clinical trial between October 2017 and October 2019.

Project description:Voluntary control over voice-hearing experiences is one of the most consistent predictors of functioning among voice-hearers. However, control over voice-hearing experiences is likely to be more nuanced and variable than may be appreciated through coarse clinician-rated measures, which provide little information about how control is conceptualized and developed. We aimed to identify key factors in the evolution of control over voice-hearing experiences in treatment-seeking (N = 7) and non-treatment-seeking (N = 8) voice-hearers. Treatment-seeking voice-hearers were drawn from local chapters of the Connecticut Hearing Voices Network, and non-treatment-seeking voice-hearers were recruited from local spiritually oriented organizations. Both groups participated in a clinical assessment, and a semi-structured interview meant to explore the types of control exhibited and how it is fostered. Using Grounded Theory, we identified that participants from both groups exerted direct and indirect control over their voice-hearing experiences. Participants that developed a spiritual explanatory framework were more likely to exert direct control over the voice-hearing experiences than those that developed a pathologizing framework. Importantly, despite clear differences in explanatory framework and distress because of their experiences, both groups underwent similar trajectories to develop control and acceptance over their voice-hearing experiences. Understanding these factors will be critical in transforming control over voice-hearing experiences from a phenomenological observation to an actionable route for clinical intervention.

Project description:Molecular bacterial load assay (MBLA) rapidly quantifies viable Mycobacterium tuberculosis (Mtb) and may be useful for monitoring treatment response and treatment efficacy. We conducted a prospective study in 56 adults with pulmonary tuberculosis from whom 244 sputum samples were collected before and during the first month of treatment. We evaluated MBLA for early monitoring of bacterial burden and investigated bactericidal activities of first-line therapy in patients infected with drug susceptible and resistant isolates. Mtb loads measured by MBLA and culture were correlated after one-week (r = 0.56) and one-month (r = 0.73) of treatment. Correlations between culture and GeneXpert or microscopy were weaker during treatment. Mtb load by MBLA declined more rapidly than GeneXpert after one-week (2.73 Ct, P < 0.001; 0.95 Ct, P = 0.297, respectively) and one-month (8.94 Ct, P < 0.001; 6.78 Ct, P < 0.001). Mtb loads in multidrug resistant (MDR) infections were significantly greater than in both sensitive and poly/mono-resistance after one-week (P < 0.02) and one-month treatment (P = 0.001). MBLA performed better than GeneXpert and microscopy in comparison to culture for quantifying viable Mtb during treatment. It can be used for monitoring bacterial load during TB treatment, facilitating early detection of treatment failure thus improving outcomes.

Project description:Modifications in the structure of pharynx following adenotonsillectomy are presumed to cause changes in the voice characteristics of patients. Data on effect of tonsillectomy/adenotonsillectomy on changes in voice among Indian children are sparse. This study was thus conducted to study the effect of adenotonsillectomy/tonsillectomy on childrens' voice. It was a prospective observational study of children aged 4-15 years undergoing tonsillectomy with or without adenoidectomy. Measures of voice were noted preoperatively, 1 and 3 months post-operatively. Subjective evaluation was done using Paediatric Voice Outcome Survey (PVOS) questionnaire administered to participants' parents. Objective evaluation was done by recording and analyzing using PRAAT voice analysis software which is an open-software tool. Statistical analysis was done using the statistical software SPSS 17.0 version. There were 31 children between 4 and 14 years of age 65% being male. Adenotonsillectomy was done in 83.5%. There was statistically significant difference in the subjective scores (PVOS) pre-operatively and 3 month postoperative score (p value = 0.001). However, there was no statistically significant difference between any other pre op and post op parameters. Though the only significant post tonsillectomy voice changes noted was subjective by parents 3 months later, it does raise concern whether this could be a reality and not a myth. Further studies with larger number of patients, including involving the subjective evaluation (PVOS) by another person in addition to patients' parent need to be undertaken to address this issue.

Project description:Trismus is a frequent complication of healed Noma infection and is caused by soft tissue and muscle contraction. Free-flap surgery is recommended to replace the missing oral mucosa and soft tissue. However, significant complications can occur if this surgery is performed in places like Africa, where conditions are usually less than optimal. In 2007, the authors started to treat patients with trismus in Niamey, Niger by distracting the soft tissue and muscle constriction between the jaws with a bone distractor continuously for 1 month with the aim of achieving a mouth opening of 3 cm. The distraction was limited to 1 mm/d. performed under local anesthesia with some sedation. Minor complications such as infection in the pin holes were easily managed. In 2009, 2 patients with trismus after Noma with a follow-up of 2 years were reported. Till date, the authors have successfully performed trismus release in more than 69 patients in Niamey and Guinea Bissau. The present study analyses the results of distraction therapy in 40 patients with follow-ups until 60 months. At the end of distraction, the mean interincisal distance was 2.7 ± 0.5 cm. Mouth opening 6 months after distraction had not reverted. However, 3 to 5 years after treatment, some signs of relapse were detected, with an average mouth opening of 1.5 ± 1.9 cm. Physiotherapy was unfortunately not feasible. The presented results strongly support the efficacy of distraction therapy to correct trismus in Noma patients.
