The body of the annual report should be preceded by an executive summary. The main elements in the body of the report are as follows: Background demographic, geographic, socio-economic data, and health activities of other sectors. Health status epidemiology and key health problems. Service platform numbers and distribution of facilities and personnel. Expenditure by sub-programme and standard item. Service delivery analysis by sub-programme. Challenges as a basis for planning. Short-term actions problems which will be addressed quickly. Neuroleptic Malignant Syndrome NMS ; A potentially fatal symptom complex sometimes referred to as NMS has been reported in association with antipsychotic drugs. Clinical manifestation of NMS are hyperpyrexia, muscle rigidity, altered mental status and evidence of autonomic instability irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmias ; . The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to identify cases where the clinical presentation includes both serious medical illness e.g., pneumonia, systemic infection, etc. ; and untreated or inadequately treated extrapyramidal signs and symptoms EPS ; . Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever and primary CNS pathology. The management of NMS should include: 1. Immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy. 2. Intensive symptomatic treatment and medical monitoring. 3. Treatment of any concomitant serious medical problems for which specific treatments are available. There is no general agreement about specific pharmacological treatment regimens for uncomplicated NMS. If a patient requires antipsychotic drug treatment after recovery from NMS, the potential reintroduction of drug therapy should be carefully considered. The patient should be carefully monitored, since recurrences of NMS have been reported. Hypersensitivity to Sodium Bisulfite Perphenan ampules contain sodium bisulfite, which may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. It is seen more frequently in asthmatic than in non-asthmatic people. CNS Effects Perphenazine may impair mental and or physical abilities, especially during the first few days of therapy. Therefore, patients should be cautioned against engaging in potentially hazardous activities requiring mental alertness e.g., driving or operating machinery. Perphenazine products can lower the convulsive threshold in susceptible individuals; they should be used with caution in alcohol withdrawal and in patients with convulsive disorders. If the patient is being treated with an anticonvulsant agent, increased dosage of that agent may be required when perphenazine products are used concomitantly. Perphenazine products are not recommended for children under 12 years of age. Antiemetic Effects Perphenazine has antiemetic effects that can obscure signs of toxicity of other drugs or mask symptoms of disease e.g., brain tumor, intestinal obstruction, Reye's syndrome. Because these drugs can suppress the cough reflex, aspiration of vomitus is possible. Use in Pregnancy Safety for the use of perphenazine during pregnancy has not been established. Therefore, it is not recommended that this drug be given to pregnant patients except when, in the judgment of the physician, it is essential and the potential benefits clearly outweigh possible hazards.
