Prevalence and seroprevalence of Plasmodium infection in Myanmar reveals highly heterogeneous transmission and a large hidden reservoir of infection.

Malaria incidence in Myanmar has significantly reduced over recent years, however, completeness and timeliness of incidence data remain a challenge. The first ever nationwide malaria infection and seroprevalence survey was conducted in Myanmar in 2015 to better understand malaria epidemiology and highlight gaps in Annual Parasite Index (API) data. The survey was a cross-sectional two-stage stratified cluster-randomised household survey conducted from July-October 2015.

Have You Heard of Schistosomiasis? Knowledge, Attitudes and Practices in Nampula Province, Mozambique.

Background: Schistosomiasis is a parasitic disease which affects almost 300 million people worldwide each year. It is highly endemic in Mozambique. Prevention and control of schistosomiasis relies mainly on mass drug administration (MDA), as well as adoption of basic sanitation practices.

Multi-country comparison of delivery strategies for mass campaigns to achieve universal coverage with insecticide-treated nets: what works best?

Background: The use of insecticide-treated nets (ITNs) is widely recognized as one of the main interventions to prevent malaria. High ITN coverage is needed to reduce transmission. Mass distribution campaigns are the fastest way to rapidly scale up ITN coverage.

Depression, anxiety and non-motor symptoms on initiation of intrajejunal levodopa/carbidopa therapy.

In Parkinson's disease (PD), clinical observations and some studies suggest that depression and anxiety are linked to motor fluctuations. We studied prospectively 10 patients with advanced PD just before initiation of intrajejunal levodopa/carbidopa therapy, and after 1 and 3 months of regular treatment. Motor symptoms, motor fluctuations, non-motor symptoms, quality of sleep, symptoms of depression and anxiety were evaluated with the appropriate scales.

What happens to lost nets: a multi-country analysis of reasons for LLIN attrition using 14 household surveys in four countries.

Background: While significant focus has been given to net distribution, little is known about what is done with nets that leave a household, either to be used by others or when they are discarded. To better understand the magnitude of sharing LLIN between households and patterns of discarding LLIN, the present study pools data from 14 post-campaign surveys to draw larger conclusions about the fate of nets that leave households.

Methods: Data from 14 sub-national post-campaign surveys conducted in Ghana, Senegal, Nigeria (10 states), and Uganda between 2009 and 2012 were pooled.

Effects of levodopa on upper limb mobility and gait in Parkinson's disease.

Background: Most clinicians rely on clinical scales such as the unified Parkinson's disease rating scale (UDPRS) for evaluating parkinsonian patients and assessing their response to levodopa. Gait analysis is not commonly used, probably because of the equipment required and the time needed. Few data have been published on the relations between gait variables and measures of arm and hand mobility.

[The neurology department].

The department of neurology is devoted to the diagnosis and medical treatment of organic diseases of central nervous system (brain and spinal cord) and peripheral nervous system (peripheral nerves and muscles). Basic and clinical research in neuroscience constitute an essential activity of the department that defines its academic character. Over the years, the department of neurology has evolved from providing general neurology services to a multifaceted unit that has developed the several subspecialties of clinical neuroscience.

Should levodopa be used anymore?

Levodopa is the most potent dopaminergic oral drug available in clinical practice. After chronic treatment, many patients with Parkinson's disease develop dyskinesia and motor fluctuations which are difficult to manage. It was hoped that introduction of dopaminergic agonists could diminish these side effects while keeping the same efficacy as levodopa.

Painful arm and moving fingers: clinical features of four new cases.

The syndrome of painful arm and moving fingers associates pain in one arm or hand with involuntary movement of one or several fingers. In the four cases described, an association between a central and a peripheral nervous system lesion is demonstrated or suspected. Treatment of the condition is disappointing.

Frontotemporal dementia: a clinical-pathological study.

We report a 44-year-old female patient without any familial history of dementia presenting with increasing disturbances in behaviour and language followed by a progressive cognitive deterioration. Neuropsychological evaluation revealed a significant impairment on frontal lobe tests. A brain PET scan disclosed a severe frontal hypometabolism.

[Encephalomyelopathy associated with monoclonal gammapathy].

We describe the case of a patient with a particular form of presumably immune-mediated encephalomyelitis associated with a monoclonal cold agglutin gammapathy. Systematic autopsy showed predominantly demyelinating lesions of the brain and spinal cord. The lesions were assumed to be the immune-mediated consequences of the underlying hematologic condition.

Increased expression of high but not low molecular weight heat shock proteins in resectable lung carcinoma.

Strong expression of high-molecular-weight (HMW) heat-shock proteins (HSP) by lung carcinoma has been documented using immunohistochemistry. Far less is known about the expression of low-molecular-weight (LMW) HSP in lung cancer. We compared the quantitative expression of HMW (HSP-60, HSP-70) and LMW (HSP-27, ubiquitin) HSP in tumor and non-tumor lung tissue obtained from 47 patients undergoing surgical resection of lung carcinoma.

[Dopaminergic agonists in the treatment of Parkinson's disease].

After levodopa, dopaminergic agonists are the most powerful agents in idiopathic Parkinson's disease treatment. Used in monotherapy or rather in early combination with levodopa, they allow a dramatic reduction of long-term motor side effects of the latter: onset and peak-dose dyskinesias, early morning dystonias. Their gastro-intestinal (nauseas) and moreover psychiatric (confusion and hallucinations) side effects limit their use, notably in geriatric populations.

[Surgical treatment of Parkinson disease: indications and limitations].

Thalamotomy, a surgical lesion of the ventro-intermediate nucleus of the thalamus, is a well known surgical treatment of tremor in Parkinson's disease. Over the last years, new surgical therapies had been developed. These therapies, instead of making a lesion in the brain, consist in placing electrodes in specific areas of the brain and to inhibit neuronal function by electrical stimulation.

Audiogenic startle reflex in acute hemiplegia.

The generators of the audiogenic startle reflex (ASR) are located in the bulbopontine reticular formation. We studied the influence of acute vascular supratentorial lesions on ASR. Ten patients with hemiplegia due to hemispheric cerebral infarct were studied within 5 days of stroke onset.

Central nervous system lesions associated with Crohn's disease.

Central nervous system vasculitis is an exceptional extraintestinal manifestation of Crohn's disease. Reported here are 2 cases, highlighting the difficulty of differential-diagnosis with multiple sclerosis and stressing the importance of early immuno-suppressive therapy.

Effects of vigabatrin on motor potentials evoked with magnetic stimulation.

We studied the effect of an acute loading dose of vigabatrin on threshold of motor responses and duration of silent period elicited with cortical magnetic stimulation in normal subjects. In contrast to phenytoin, vigabatrin does not increase the motor threshold of first dorsal interosseus muscle. We also show that, although vigabatrin increases GABA concentrations in the central nervous system, duration of silent period studied at various stimulus intensities is not modified after vigabatrin administration.

Chronic intrathecal baclofen in severely disabling spasticity: selection, clinical assessment and long-term benefit.

Flexor and extensor spasms associated with severe spasticity frequently cause pain and suffering in neurologically impaired patients, and greatly interfere with comfort and activities. When high doses of oral medications are necessary to keep the symptoms under control and are poorly tolerated, the long-term spinal-selective intrathecal infusion of baclofen by means of implanted drug pump and catheter is a safe, efficient and reversible alternative to destructive surgical procedures. Between September 1991 and March 1995, intrathecal baclofen was infused in 18 selected patients out of a series of 42 severely disabled spastic cases.

Abnormal motor evoked responses to transcranial magnetic stimulation in focal dystonia.

We evaluated motor responses evoked after magnetic cortical stimulation in dystonia, emphasizing the relationship between resting and facilitation state. We studied 15 normal controls (mean age, 37.9 years; range, 23 to 63) and 13 dystonic patients (mean age, 43.

Effects of diphenylhydantoin on motor potentials evoked with magnetic stimulation.

We studied the effect of an acute loading dose of diphenylhydantoin (DPH) on motor responses elicited with cortical magnetic stimulation in normal subjects. DPH increased significantly the motor threshold activation of ADM, APB, FDI and biceps. The motor threshold increase was of greater magnitude for the proximal muscle.
