RESUMEN
INTRODUCTION: Autonomous twitch elicitation at myofascial trigger points from spondylotic radiculopathies-induced denervation supersensitivity can provide favourable pain relief using electrical twitch-obtaining intramuscular stimulation (ETOIMS). AIM: To provide objective evidence that ETOIMS is safe and efficacious in migraine and persistent pain management due to decades-old injuries to head and spine from paediatric American football. METHODS AND MATERIALS: An 83-year-old mildly hypertensive patient with 25-year history of refractory migraine and persistent pain self-selected to regularly receive fee-for-service ETOIMS 2/week over 20â months. He had 180 sessions of ETOIMS. Pain levels, blood pressure (BP) and heart rate/pulse were recorded before and immediately after each treatment alongside highest level of clinically elicitable twitch forces/session, session duration and intervals between treatments. Twitch force grades recorded were from 1 to 5, grade 5 twitch force being strongest. RESULTS: Initially, there was hypersensitivity to electrical stimulation with low stimulus parameters (500â µs pulse-width, 30â mA stimulus intensity, frequency 1.3â Hz). This resolved with gradual stimulus increments as tolerated during successive treatments. By treatment 27, autonomous twitches were noted. Spearman's correlation coefficients showed that pain levels are negatively related to twitch force, number of treatments, treatment session duration and directly related to BP and heart rate/pulse. Treatment numbers and session durations directly influence twitch force. At end of study, headaches and quality of life improved, hypertension resolved and antihypertensive medication had been discontinued. CONCLUSIONS: Using statistical process control methodology in an individual patient, we showed long-term safety and effectiveness of ETOIMS in simultaneous diagnosis, treatment, prognosis and prevention of migraine and persistent pain in real time obviating necessity for randomised controlled studies.
RESUMEN
Chronic pain with a 30.3% global prevalence significantly impacts universal health. Low back pain has a 9.4% prevalence worldwide causing the most widespread disability. Neck pain ranks 4th highest regarding years lived with disability with a 4.9% prevalence worldwide. The principal cause of pain in 85% of patients visiting a tertiary pain clinic has a myofascial origin. The root cause is multifocal neuromuscular ischaemia at myofascial trigger points from muscle tightening and shortening following spondylotic radiculopathy induced partial denervation. Chronic refractory myofascial pain (CRMP) is a neuromusculoskeletal disease needing management innovations. Using electrical twitch-obtaining intramuscular stimulation (eToims), we provide objective evidence of denervation supersensitivity in multiple myotomes as cause, aggravation and maintenance of CRMP. This study underscores our previous findings that eToims is safe and efficacious for long-term use in CRMP. eToims aids potential prevention (pre-rehabilitation), simultaneous diagnosis, treatment (rehabilitation) and prognosis in real time for acute and CRMP management.

The low-lying excited states (La and Lb) of polyacenes from naphthalene to heptacene (N = 2-7) are studied using various time-dependent computational approaches. We perform high-level excited-state calculations using equation of motion coupled cluster with singles and doubles (EOMCCSD) and completely renormalized equation of motion coupled cluster with singles, doubles, and perturbative triples (CR-EOMCCSD(T)) and use these results to evaluate the performance of various range-separated exchange-correlation functionals within linear-response (LR) and real-time (RT) time-dependent density functional theories (TDDFT). As has been reported recently, we find that the range-separated family of functionals addresses the well-documented TDDFT failures in describing these low-lying singlet excited states to a large extent and are as about as accurate as results from EOMCCSD on average. Real-time TDDFT visualization shows that the excited state charged densities are consistent with the predictions of the perimeter free electron orbital (PFEO) model. This corresponds to particle-on-a-ring confinement, which leads to the well-known red-shift of the excitations with acene length. We also use time-dependent semiempirical methods like TD-PM3 and TD-ZINDO, which are capable of handling very large systems. Once reparametrized to match the CR-EOMCCSD(T) results, TD-ZINDO becomes roughly as accurate as range-separated TDDFT, which opens the door to modeling systems such as large molecular assemblies.
RESUMEN
SETTING: Kisenyi slum in peri-urban Kampala, Uganda. OBJECTIVES: Using chronic cough (> or = 2 weeks) inquiry as a screening tool to identify undetected smear-positive tuberculosis (TB) cases and to describe the characteristics of smear-positive TB cases detected by active case finding. DESIGN: A house-to-house survey was conducted in five randomly selected villages in Kampala between June and August 2005. A sample of households was visited; adults aged > or = 15 years were consecutively interviewed to identify those with chronic cough. Three sputum specimens were collected and examined by smear microscopy. RESULTS: Among 930 individuals, we identified 189 (20%) chronic coughers. Of these, we found 33 (18%) undiagnosed smear-positive cases. The newly detected cases had an even sex distribution (P = 0.47), a median age of 30 years, a median cough duration of 1 month and 55% had acid-fast bacilli 1+ sputum smear grade. CONCLUSION: These findings suggest that active case finding could supplement DOTS to yield additional smear-positive TB cases, lead to early diagnosis and thus shorten the duration of infectiousness before effective chemotherapy is initiated. In communities such as Kisenyi, this is a feasible strategy that may prove useful for TB control, but its cost-effectiveness needs to be evaluated. Early health care seeking for cough should be emphasized.

OBJECTIVE: To assess whether linkage of tuberculosis (TB) and HIV/AIDS increases the perception of stigma among TB patients on Community-Based Directly Observed Therapy (CB-DOT) compared to similar TB patients on self-administered therapy (SAT). DESIGN: A Cross-sectional study. SETTING: Kiboga (CB-DOT) and Mubende (SAT) districts, Uganda in 2000. SUBJECTS: One hundred and five tuberculosis patients on CB-DOT and 202 patients on SAT. One hundred and twenty one (39%) of these patients agreed to be tested for HIV. RESULTS: Patients on CB-DOT and patients on SAT were similar on most of the domains used to assess stigma associated with a TB diagnosis, except for the domain of TB diagnosis and general belief that TB and HIV/AIDS are linked. Patients on CB-DOT were more likely to believe that neighbours knew they had TB compared to patients on SAT (91% vs. 62%, p < 0.001), but the groups did not differ in their perception that neighbours thought they have HIV because of TB (46% vs. 46%, p = 0.954). HIV prevalence was similar in both groups. CONCLUSION: The study demonstrates that TB patients on CB-DOT did not differ from SAT patients in their perception of stigma as a result of TB. Therefore, HIV-related stigma may not limit wide implementation of CB-DOT in countries like Uganda.
