OBJECTIVE: X-linked dystonia parkinsonism (XDP) is an adult-onset, progressive and debilitating movement disorder described among Filipino males from Panay Island. The available oral medications have been ineffective. While chemodenervation with botulinum toxin A works and deep brain stimulation surgery is promising, these are not affordable for the vast majority of patients. Thus, we decided to look into the efficacy, safety and tolerability of levodopa+carbidopa (levodopa) versus placebo among patients with XDP.

METHODS: This was a double blind, randomized, placebo-controlled clinical trial. Patients were randomized to receive levodopa or placebo for 6 months. The dose was increased gradually until 1000 mg levodopa/day is reached or until side effects appear.

RESULTS: A total of 86 out of 94 randomized patients (91.5%) were included in the intention-to-treat cohort for the primary efficacy analysis. Nineteen patients (9 in levodopa, 10 in placebo) dropped out or were lost to follow up. There was no significant difference in the baseline and last visit Burke Fahn Marsden Dystonia Rating Scale and the part III of the Unified Parkinson's Disease Rating Scale scores between levodopa and placebo. The most common adverse events in the levodopa group were increased movements, pain and nausea/ vomiting.

CONCLUSION: While levodopa is safe and well-tolerated, it does not have any effect in alleviating the dystonia or parkinsonism in XDP.

ABSTRACT:

BACKGROUND: The Millennium Development Goal (MDG) for 2015 has a target MMR of 52/100,000 live births but this goal been difficult to achieve. In the Philippines, 11 mothers die everyday from pregnancy related complications, a bulk contributed by Hypertension. Public health midwives sometimes attend to these obsterical emergencies often in the absence of a physician. this led to the BEmONC program, which addresses the rising morbidities from far-flung areas where resources are scarce, and helps train midwives in essential obsterical emergency care. The midwives are our allies in providing the best standard of care every mother and child rightfully deserves. Only thru periodic evaluation can we help strengthen BEmONC program, making it crucial to evaluate the midwives' knowledge and management practices in hypertension to help identify the setbacks that have impeded our progress in achieving the MDG.

GENERAL OBJECTIVE: To access the knowledge and management practices of midwives in the management of hypertension in pregnancy in accourdance to the BEmONC protocol.

STUDY DESIGN: Descriptive Study

STUDY SETTING: The 69 public health centers of Cebu City

STUDY POPULATION: Public Health Midwives

METHODOLOGY:This is descriptive study where a survey questionnaire was used and convenience sampling was done. Chi square and Fischer exact tests were employed to compare proportions. Descriptive statistics was used to summarize the data in proportion.

RESULT: More than 70% of the midwives were knowledgeable regarding expected competencies, where BEmONC-trained midwives were 5-14x more likely to identity appropriate function. However, Only a dismal 22-36% will actually administer Magnesium Sulfate, which shows that knowledge is not translated into practice. Also, more than 70% were knowledgeable on the risk factors and danger signs of hypertension in pregnancy. It also showed that the midwives agreed to give antihypertensive medications- where Methyldopa was commonly given. Among those who agreed too give Methyldopa, majority were BEmONC-trained. A number also agreed to give hydralazine and diazepam in the setting of sever preeclampsia and eclampsia, where more non-BEmONC midwives agreed. Alarmlingly, only less than 50% will refer to a physician in the management og gestational hypertension and mild preeclampsia, and only 50%-60% agreed to facilitate hospital transport in the setting of severe preeclampsia and eclampsia.

CONCLUSION: The BEmONC manual must be updated to keep up with current guidelines and ensure the conversation of knowledge into practice. The BEmONCcoverage of training must also be expanded so that all practicing midwives know the protocol. However, the DOH must further strengthen their role in the active surveillance of public health midwives and review the retention of their skills and regular practice of knowledge. Midwives must also be certified proficient, not merely trained. The must also be consulted to explore their problems in the implementation of current guidelines so we can better understand their situation as to why knowledge is not put into practice. By identifying deficiencies, we can improve and address setbacks that have impeded our progress towards achieving the Millennium Development Goal.

PURPOSE: Levodopa is the most effective anti-Parkinsonian agent. It has also been known to exhibit analgesic properties in laboratory and clinical settings. However, studies evaluating its effects on neuropathic pain are limited. The aim of the present study was to examine the anti-allodynic effects of levodopa in neuropathic rats. MATERIALS AND METHODS: Sprague-Dawley male rats underwent the surgical procedure for L5 and L6 spinal nerves ligation. Sixty neuropathic rats were randomly divided into 6 groups for the oral administration of distilled water and levodopa at 10, 30, 50, 70, and 100 mg/kg, respectively. We co-administered carbidopa with levodopa to prevent peripheral synthesis of dopamine from levodopa, and observed tactile, cold, and heat allodynia pre-administration, and at 15, 30, 60, 90, 120, 150, 180, and 240 min after drug administration. We also measured locomotor function of neuropathic rats using rotarod test to examine whether levodopa caused side effects or not. RESULTS: Distilled water group didn't show any difference in all allodynia. For the levodopa groups (10-100 mg/kg), tactile and heat withdrawal thresholds were increased, and cold withdrawal frequency was decreased dose-dependently (p<0.01). In addition, levodopa induced biphasic analgesia. Different dosage of levodopa did not impact on the rotarod time (p>0.05). CONCLUSION: Levodopa reversed tactile, cold and heat allodynia in neuropathic rat without any side effects.

BACKGROUND: XDP is an X-linked recessive disorder characterized by parkinsonism and dystonia described among Filipinos. Oral medications are frequently ineffective. Lately, DBS have been promising. However these are not generally available or affordable for the vast majority of patients. We then decided to evaluate the effectiveness of levodopa-carbidopa for XDP.
OBJECTIVE: To compare the efficacy, safety and tolerability of levodopa-carbidopa vs. placebo in XDP patients.
METHODS: After informed consent and randomization, the BFM and the UPDRS parts III and IV were performed at baseline and monthly up to 6 months. Patients were randomized to receive either levodopa-carbidopa at a starting dose of 125 mg levodopa/ day in 2 divided doses or corresponding placebo. Gradual uptitration was done to a maximum of 1000 mg levodopa/ day or until side effects appeared.
Homogeneity of the characteristics of patients in the 2 groups was determined using Independent t-test and Chi-square test. To determine the significance of changes in the efficacy parameters within each group, Wilcoxon Matched Pairs Signed Ranks Test was used. To compare the scores of the different efficacy parameters of the 2 groups, Mann Whitney U Test was applied to the data. A p?0.050 was considered significant.
RESULTS: A total of 107 patients were recruited. There were 13 screen failures, and 94 were subsequently enrolled. The baseline characteristics (age, duration of illness, baseline BFM and UPDRS (motor) scores were not significant between levodopa and placebo (age in years: 47 + 9.35 vs. 50 + 9.51; duration of illness in years 6.3 + 7 vs. 6.2 + 5.2; BFM score: 32.8 + 24.5 vs. 28.4 + 26.5; UPDRS score 29.9 + 20.7 vs. 34.8 + 26.8).
There was a decrease in BFM scores from baseline to all follow-up periods in patients given levodopa but were statistically significant only on visit 2 and visit 9. In the placebo group, decrease in scores was also observed in some observation periods but no statistical significance was shown. A comparison of the 2 groups showed that the magnitude of decrease in the levodopa group was statistically greater than the placebo group on the second visit. There were no significant differences observed in all other follow-up periods. Both groups showed a decrease in UPDRS scores but significant decrease was observed in visits 2, 5, 6, 7, 9 of the levodopa group. While in the placebo group, a significant decrease was observed only on visit 2. Comparison of the 2 groups did not show any significant differences.
There were 17 patients from the levodopa group who reported adverse events (most common: increased involuntary movements, nausea/ vomiting/ dizziness, headache, and generalized weakness. In the placebo group, there were 11 patients (most common: increased involuntary movements, abdominal pain). There were 9 patients who dropped out (levodopa: 4, placebo: 5).
CONCLUSION: There was a significant decrease in the BFM and UPDRS scores in XDP patients given levodopa compared to placebo. Levodopa is a safe and effective drug that may be considered in patients with XDP.

OBJECTIVES: To present a case of childhood primary dystonia with good response to zolpidem.
INTRODUCTION: Dystonia is a syndrome of sustained muscle contractions causing twisting and repetitive movements or abnormal postures. It is not uncommon in children. Although there are several options to treat dystonia,its medical treatment is notoriously difficult and often unsuccessful. Zolpidem, an imidazopyridine agonist with a high affinity to benzodiazepine subtype receptor BZ1, is reported to improve basal ganglia disease including Parkinson'sdisease and various types of dystonia.
THE CASE: 11 year old female with torticollis starting the 7years old. At q10years old symptoms progressed with her back hyperexteded. Her cranial MRI was normal. She was started on Levodopa and carbidopa however no improvement of symptoms was noted. She was started on zolpidem and there was a marked improvement in speech, writing, swallowing, walking and posture observed.
DISCUSSION: Primary dystonia is defined as syndromes in which dystonia is the sole phenotypic manifestation. There is no cognitive decline and cranial MRI is normal. Management of childhood dystonia differs in certain respects from that of adult dystonia. Dopamine responsive dystonia in children is rare, but a trial of L-dopa should be performed on all patients rith childhood-onset dystonia. Dystonia is associated with hypoactivity of the globus pallidus interna, and widespread brain alterations in GABAA/benzodiazepine receptors. Zolpidem binding sites are abundant in the basal ganglia output structure the globus pallidus interna and substantia nigra pars reticulata. It is thought that by binding to these sites, zolpidem help restore Ie ganglionic output influence to the thalamus and motor cortex.
CONCLUSION: There are several options to treat dystonia,its medical treatment is notoriously difficult and often unsuccessful. Zolpidem an imidazopyridine agonist can be given in childhood dystonia unresponsive to dopamine.

Hyperphenylalaninemia can result from defects in either the phenylalanine hydroxylase (PAH) enzyme or in the synthesis or recycling of the active pterin, tetrahydrobiopterin (BH4), which is an obligate co-factor for the PAH enzyme, as well as tyrosine hydroxylase and tryptophan hydroxylase. One of the most common causes of BH4 deficiency is a defect in the synthesis of 6-pyruvoyltetrahydropterin synthase (PTPS) enzyme. Patients present with progressive neurological disease such as mental retardation, convulsions and disturbance of tone and posture despite strict adherence to diet and good metabolic control. The authors report the first two cases of PTPS deficiency in the Philippines. Both are females with initial phenylalanine levels of more than 1300 umol/L who continued to develop neurologic deterioration despite good metabolic control and strict adherence to diet. Further investigation showed that they both had PTPS deficiency. Treatment was started with BH4, L-dopa/carbidopa, and 5-hydroxytryptophan (5HT) with concomitant significant improvements in their neurologic and developmental outcomes.

Drug-induced toxic hepatitis is a relatively common hepatic disease in children, and it is usually self-limiting upon cessation of the offending drugs. Antituberculous drugs are well known for inducing hepatitis. Some cases of drug-induced hepatitis with autoimmune features have been reported; in these cases, the offending drugs were usually methyldopa, nitrofurantoin, minocycline, and interferon. The authors report the first case in Korea of drug-induced autoimmune hepatitis associated with thyroiditis and multiple autoantibodies that was induced by the antituberculous drugs isoniazid and rifampin.

BACKGROUND: Cognitive impairments are common in patients with Parkinson's disease (PD). However little is known about the cognitive effects of dopaminergic therapy. METHODS: The study was a single-blind prospective study of 21 patients with PD. Each patient had received either levodopa (Sinemet(R), n=8) or dopamine agonist (Requip(R), n=13) during 24 consecutive weeks. Neuropsychological battery, including Korean version of Alzheimer's Disease Assessment Scale(R) cognitive subscale (ADAS-Cog) and frontal-executive function part of SNSB (Seoul Neuropsychological Screening Battery), were performed two times, before and after the 24 weeks of management. Patients also received quantitative ratings of motor symptom severity and functional status using Unified Parkinson's Disease Rating Scale (UPDRS) before and after the dopaminergic therapy. RESULTS: After six months of treatment, motor scale improved in both groups (p<0.05) without difference between the groups (p>0.05). In ADAS-Cog testing, Requip(R) group improved at more categories than Sinemet(R) group but without statistical difference (p>0.05). The results of frontal-executive function test did not differ between the groups, either. CONCLUSIONS: Our study does not provide an evidence that dopaminergic treatment improves cognitive functions in Parkinson's disease. Furthermore, we found no significant difference in the effect on cognition between the two tested drugs and no difference in the results of the above-listed neuropsychological tests between the first and the last visits.

Akinetic mutism is a clinical syndrome in which the patient is unable to speak (mutism) or move (akinesia). Various brain lesions can induce akinetic mutism. We attended a 71-year-old woman who presented with akinetic mutism caused by bilateral anterior cerebral artery infarction. The patient improved after the administration of levodopa com-bined with carbidopa, in response to visual and verbal stimuli. Increased verbal output and spontaneous motor activities were also noted. Levodopa may be helpful to the treatment of akinetic mutism.
