Clinical Trials Related to Sulfacetamide (Sulfacetamide Ophthalmic)
Effects of Brain Stimulation on Learning and Reasoning [Completed]
Imaging studies of the brain have revealed the different areas involved in the processes of
learning and reasoning. However, the specific role these regions play in these processes, or
if stimulating these areas can improve these processes is unknown.
Researchers would like to use repetitive transcranial stimulation (rTMS) to better understand
the roles of individual brain regions on the processes of learning and reasoning. Repetitive
transcranial magnetic stimulation (rTMS) involves the placement of a cooled electromagnet
with a figure-eight coil on the patient's scalp, and rapidly turning on and off the magnetic
flux. This permits non-invasive, relatively localized stimulation of the surface of the
brain (cerebral cortex). The effect of magnetic stimulation varies, depending upon the
location, intensity and frequency of the magnetic pulses.
The purpose of this study is to use rTMS to help determine the roles of different brain
regions in the development of implicit learning of motor sequences and analogic reasoning.
In addition, researchers hope to evaluate if stimulation of these regions speeds up the
process of learning or analogic reasoning.
SOLID-Effect of Risedronate Sodium at Distal Radius in Colle's Fracture. [Recruiting]
The purpose of this study is to evaluate the efficacy and safety of risedronate sodium
(Actonel®) after a wrist fracture in postmenopausal women.
Efficacy and Safety of Dihydroartemisinin/Piperaquine (Artekin®) for the Treatment of Uncomplicated Malaria in Peru [Completed]
In Peru, Mefloquine plus Artesunate (MAS3), is the current first line treatment for P.
falciparum malaria in the Amazonian Region, and has proved its efficacy against
multi-resistant P. falciparum parasites, but several side effects have been reported.
Dihydroartemisinin-piperaquine (DHA-PPQ) is a new co-formulated and well tolerated ACT,
increasingly used in Southeast Asia where it has proved to be highly effective against
Plasmodium falciparum malaria. We tested the efficacy, safety and tolerability of DHA-PPQ in
patients with uncomplicated P. falciparum malaria. A RCT to evaluate DHA-PPQ was carried out,
between 2003 and 2005. Patients with uncomplicated P. falciparum malaria were randomly
allocated to receive either DHA-PPQ or MAS3 with a 63-day follow-up period. Five hundred
twenty two patients were included in the analysis, 262 were allocated to receive DHA-PPQ, and
260 to receive MAS3. The two groups were comparable at baseline in demographic and clinical
characteristics. The mean time for parasite clearance into the DHA-PPQ group was 32. 0 hours
and 35. 5 hours in the MAS3 group. Twenty-four hours after the first dose, the proportions of
patients whose cleared parasitaemia were 67. 2% in the DHA-PPQ group, and 58. 1% in the MAS3
group (RR 1. 25, [95% CI 1. 03â1. 52], p = 0. 017). All patients were able to clear parasites
within 72 hours after the first dose. The mean time for fever clearance was 28. 0 and 29. 5
hours in DHA-PPQ and MAS3 group respectively. (P= 0. 69). Twenty-four hours after the first
dose, 85. 5% and 83. 1% of patients cleared fever in the DHA-PPQ and MAS3 group respectively
(p>0. 05). The Adequate Clinical and Parasitological Response (ACPR), PCR adjusted, were 97. 7%
and 99,2% for the DHA-PPQ and MAS3 group respectively, (RR 0. 99, 95% CI [0. 86â1. 13], P =
0. 88). No Early Treatments Failures were reported in any group. In the DHA-PPQ group,
according to the PCR adjusted results, 6 subjects had Late treatment Failures. In the MAS3
group, two Late Treatment Failures was reported. The frequency of adverse events was
significantly lower in patients treated with DHA-PPQ than in those treated with MAS3.
DHA-PPQ proved to be a highly effective antimalarial drug for the treatment of P. falciparum
malaria and suitable for use in the Peruvian Amazon region. It also has the advantage of
being better tolerated. In terms of cost, DHA-PPQ is cheaper and more affordable than MAS3
and should be considered for the National Antimalarial Drug Policy in Perú.
BURULICO Drug Trial Study Protocol: RCT SR8/SR4+CR4, GHANA [Active, not recruiting]
The standard for treatment Buruli ulcer disease (BUD) used to be surgery but the WHO now
advises streptomycin (S, 15 mg/kg daily, intramuscularly) and rifampicin (R,10 mg/kg daily)
along with surgery. This preliminary advice was based on observations in 21 patients with
pre-ulcerative lesions of BUD, who were given daily SR treatment for varying periods of time.
In patients treated with SR for at least 4 weeks, M. ulcerans could no longer be cultured
from excised lesions. SR has been introduced without a formal evaluation or comparison with
other treatments have been conducted or published, but the impression is that this treatment
is beneficial and may cure BUD without additional surgical management.
This study protocol evaluates the hypothesis that early, limited lesions of
BUD(pre-ulcerative or ulcerated lesions, ≤ 10 cm maximum diameter), can be healed without
recurrence using antimycobacterial drug therapy, without the need for debridement surgery.
In endemic regions in Ghana, patients will be actively recruited and followed if ⥠5 years of
age, and with early (i. e., onset < 6 months) BUD.
- consent by patients and / or care givers / legal representatives
- clinical evaluation, and by
- analysis of three 0. 3 cm punch biopsies under local anaesthesia.
- disease confirmation: dry reagent-based polymerase chain reaction (DRB-PCR IS2404)
- randomization: either SR for 8 weeks, or 4 weeks of SR followed by R and clarithromycin
(C)
- stratification: ulcerative or pre-ulcerative lesions.
Biopsies will be processed for histopathology, DRB-PCR-, microscopy, culture, genomic, and
sensitivity tests. Lesions will be assessed regularly for progression or healing during
treatment. Drug toxicity monitoring includes blood cell counts, liver enzymes and renal
tests; and ECG and audiographic tests.
Primary endpoint: healing without recurrence at 12 months follow-up after start of treatment
Secondary endpoint: reduction in lesion surface area and/or clinically assessed improvement
on completion of treatment, averting the need for debridement surgery.
Recurrences will be biopsied for confirmation, using PCR, histopathology, and culture. Sample
size: 200 patients, with 2x74 evaluable patients to be randomized; 80% power to detect a
difference of 20 % in recurrence-free cure 12 months after start of treatment between the two
groups (60 versus 80%). A Data Safety and Monitoring Board will make interim analyses.
Bone Mineral Density, Body Composition and Growth Following Severe Burn Injury [Recruiting]
We hypothesize that bone mineral content is diminished in children aged 4-18 following burn
injury. This is based on data in burned children in other regional hospitals as well as
findings in our own population of marginal growth delay following burn injury. Our
objectives are two-fold. The first goal is to establish that diminished bone mineral density
is a long-term problem among children admitted to this regional burn hospital as compared to
healthy children in the region. This is important particularly since bone health may be
region specific, or may even relate to modes of care that vary from hospital to hospital
during the acute and convalescent phases of injury. There is no data on bone mineral density
in burned children in regions outside of the Southwestern portion of the USA. Also,
comparisons to healthy children living in this region using the same scanning machine are
needed.
The second purpose of this study is to test the effects of calcium and vitamin D
supplementation in burned children on bone accrual in burned children. In this 2-year study,
children aged 4-18 who have been previously burned will take either a calcium supplement with
vitamin D or a placebo for one year. We will evaluate patients every 6 months for 2 years
(patients will be measured 6 months and 1 year after the 1 year treatment to find out if the
supplement group maintained any increase in bone formation that occurred during the 1-year
treatment.
