Post-poliomyelitis respiratory impairment is extremely common and entails considerable risk of morbidity and mortality. Respiratory muscle weakness is the primary etiological factor but post-poliomyelitis individuals (PPIs) also have a high incidence of scoliosis, obesity, sleep disordered breathing, and bulbar muscle dysfunction, all of which can add to the risk. One hundred forty-five PPIs were managed by noninvasive alternatives to intermittent positive pressure ventilation (IPPV) via an indwelling tracheostomy. When properly managed in this manner, acute respiratory failure requiring hospitalization, tracheal intubation, and bronchoscopies were avoided. Timely introduction of mouthpiece IPPV, nasal IPPV, manually and mechanically assisted coughing, and noninvasive blood gas monitoring in the home were the principal techniques used for optimizing quality of life and for avoiding complications.

Immune response of infants vaccinated under Expanded Programme on Immunization (EPI) was evaluated for measles, poliomyelitis, and tuberculosis in Ifo/Otta area of Ogun State and Badagry area of Lagos State, Nigeria. In the prevaccination evaluation of measles antibody, 59 per cent were protected and 41 per cent were at risk in Ifo/Otta area, while 49 per cent were protected and 51 per cent were at risk in the Badagry area. After measles vaccination, 89 per cent of those evaluated seroconverted and 11 per cent did not in Ifo/Otta area, while in Badagry area, 86 per cent of those evaluated seroconverted and 14 per cent did not. For polio neutralizing antibody evaluated at post-immunization, 91 per cent seroconverted, while 9 per cent did not in Ifo/Otta area, while in Badagry area 66 per cent seroconverted and 34 per cent did not. Tuberculin test was used to evaluate the cellular response to BCG vaccination against tuberculosis. 64 per cent were found protected, while 18 per cent were at risk in both areas examined and 18 per cent dropped out. Using Gomez method to evaluate the nutritional status of the infants, 34 per cent were malnourished in Ifo/Otta area and are mostly immigrants. In Badagry area, 53 per cent were normal while 47 per cent were malnourished and most of the malnourished infants were plagued with diarrhoea, severe cough, high fever or malaria infection. Most of the malnourished in the two areas screened were between 9 and 18 months of age, which is the crucial period in the growing stage of the children.(ABSTRACT TRUNCATED AT 250 WORDS)

Pulmonary complications from impaired airway secretion clearance mechanisms are major causes of morbidity and mortality for post-poliomyelitis individuals. The purpose of this study was to review the long-term use of manually assisted coughing and mechanical insufflation-exsufflation (MI-E) by post-poliomyelitis ventilator-assisted individuals (PVAIs) and to compare the peak cough expiratory flows (PCEF) created during unassisted and assisted coughing. Twenty-four PVAIs who have used noninvasive methods of ventilatory support for an average of 27 years, relied on methods of manually assisted coughing and/or MI-E without complications during intercurrent respiratory tract infections (RTIs). Nine of the 24 individuals were studied for PCEF. They had a mean forced vital capacity (FVC) of 0.54 +/- 0.47L and a mean maximum insufflation capacity achieved by air stacking of ventilator insufflations and glossopharyngeal breathing of 1.7L. The PCEF were as follows: unassisted, 1.78 +/- 1.16L/sec; following a maximum assisted insufflation, 3.75 +/- 0.73L/sec; with manual assistance by abdominal compression following a maximum assisted insufflation, 4.64 +/- 1.42L/sec; and with MI-E, 6.97 +/- 0.89L/sec. We conclude that manually assisted coughing and MI-E are effective and safe methods of airway secretion clearance for PVAIs with impaired expiratory muscle function who would otherwise be managed by endotracheal suctioning. Severely decreased maximum insufflation capacity but not vital capacity indicate need for a tracheostomy.

At immunization contact, 165 infants 2.5 mo old were randomly assigned to receive either 15 mg vitamin A (retinyl palmitate) or placebo. Three doses were given at monthly intervals with each diphtheria, pertussis, tetanus and oral polio (DPT/OPV) immunization dose. The diarrhea and acute respiratory infection (ARI) morbidity was similar in the vitamin A and placebo groups. However, the duration (days per child-year, mean +/- SD) of ARI was less in the vitamin A group compared with placebo group (27.6 +/- 17.1 vs. 40.8 +/- 22.7; P = 0.005). Fasting retinol concentrations were measured at entry and in 61 infants, the relative dose response (RDR) test was done 1 mo after the third dose of vitamin A. Eighty-five percent of the infants had serum retinol concentration < 0.70 mol/L at entry. After 3 mo the serum retinol levels improved significantly in both groups, and in the vitamin A-supplemented group the serum retinol concentration was significantly better than that in the placebo group (P= 0.02). However, 61% of the infants remained deficient despite vitamin A supplementation. Among vitamin A-supplemented infants only, diarrhea and ARI morbidity during the 3-mo period were compared in children with normal versus children with abnormal RDR at the end of the supplementation period. The ARI episodes were more frequent in the supplemented infants who remained vitamin A deficient at the end of the 3 mo (P = 0.027). Also, the cumulative duration (days, mean +/- SD) of fever and cough was 5.0 +/- 2.8 in the normal versus 11.2 +/- 6.0 in the deficient group (P = 0.04). The results of this study suggest that a large proportion of infants remain vitamin A deficient even after large dose vitamin A supplementation because of frequent respiratory infections, particularly those accompanied by fever.

A 62-year-old man was admitted to our hospital with complaints of coughing and fever. He had poliomyelitis at the age of 4 years, and had experienced difficulty in swallowing and chronic aspiration for the past 3 years. A chest roentgenogram and a high-resolution CT scan obtained on admission showed many small nodular shadows in the lower lung fields. Cricopharyngeal myotomy was done to decrease aspiration. The patient was then able to eat without aspiration, and the chest-roentgenographic and CT findings improved. Diffuse aspiration bronchiolitis was diagnosed from the clinical course and the radiographic findings. Cricopharyngeal myotomy can reduce the risk of aspiration in patients with diffuse aspiration bronchiolitis.

Airway clearance techniques are indicated for specific diseases that have known clearance abnormalities (Table 2). Murray and others have commented that such techniques are required only for patients with a daily sputum production of greater than 30 mL. The authors have observed that patients with diseases known to cause clearance abnormalities can have sputum clearance with some techniques, such as positive expiratory pressure, autogenic drainage, and active cycle of breathing techniques, when PDPV has not been effective. Hasani et al has shown that use of the forced exhalatory technique in patients with nonproductive cough still resulted in movement of secretions proximally from all regions of the lung in patients with airway obstruction. It is therefore reasonable to consider airway clearance techniques for any patient who has a disease known to alter mucous clearance, including CF, dyskinetic cilia syndromes, and bronchiectasis from any cause. Patients with atelectasis from mucous plugs and hypersecretory states, such as asthma and chronic bronchitis, patients with pain secondary to surgical procedures, and patients with neuromuscular disease, weak cough, and abnormal patency of the airway may also benefit from the application of airway clearance techniques. Infants and children up to 3 years of age with airway clearance problems need to be treated with PDPV. Manual percussion with hands alone or a flexible face mask or cup and small mechanical vibrator/percussors, such as the ultrasonic devices, can be used. The intrapulmonary percussive ventilator shows growing promise in this area. The high-frequency oscillator is not supplied with vests of appropriate sizes for tiny babies and has not been studied in this group. Young patients with neuromuscular disease may require assisted ventilation and airway oscillations can be applied. CPAP alone has been shown to improve achievable flow rates that will increase air-liquid interactions for patients with these diseases or airway malacia. Use of positive pressure to maintain airway patency in these children allows cephalad clearance of secretions. Patients with segmental atelectasis, particularly related to asthma, may benefit from intrapulmonary percussive ventilator, positive expiratory pressure, or PDPV. Prevention of postoperative atelectasis is particularly well suited to positive expiratory pressure, which is not as painful as techniques using oscillations. Neurologically abnormal patients who are unable to cooperate with any active method are also treated using intrapulmonary percussive ventilator, PDPV, and suctioning, if necessary. Musculoskeletal abnormalities, muscular dystrophies, myasthenia gravis, poliomyelitis, or other similar diseases require stabilization of bellows function. Optimizing ventilation in patients with such abnormalities may require positive pressure ventilation either during sleep or continuously. Externally applied pressure, such as with the In-Exsufflator or the cyclically inflated pneumatic belt, can augment the patient's own efforts and is sometimes helpful. Normalizing the vital capacity and functional residual capacity typically helps to improve the ability to cough and clear secretions. Assisted cough devices or maneuvers are described in other papers by Bach and Hill. Not all patients who have weak muscles require nocturnal or continuous support, and may benefit from positive expiratory pressure mask treatments. Further studies are sorely needed for this population. Long-term controlled trials are urgently needed to help establish the best types of treatment for patients with CF and bronchiectasis. Such studies will become more complicated by the introduction of new treatments, such as DNase and other therapies that alter secretions, and may begin to change mucociliary or cough clearance. The selection of appropriate outcome measures is central to studying these questions, and it is unclear which are the most important. (ABSTRACT TRUNCATED)

Child survival in Cameroon is measured in the 1991 Demographic and Health Survey and found to be substantially improved. The survey includes a sample of 3871 women aged 15-49 years and a sample of 814 husbands. Community services data is also collected. Child mortality is reported as declining from 198 to 126 deaths per 1000 births during 1976-91. Infant mortality is shown to decline to 65/1000. Mortality of children aged 1-4 years is 66/1000. 79% receive prenatal care from some source, and 70% receive a dose of tetanus toxoid vaccine during pregnancy. A health professional is present at delivery for 64% of pregnant women. 52% of children aged 12-23 months have a health card, and 41% have tuberculosis, polio, diphtheria, pertussis, tetanus, and measles immunization. One in five still does not have any immunization. 62% of children with mothers who have at least a secondary school education are immunized. Diarrhea morbidity in the two weeks preceding the survey is 18% for children aged under 5 years. 9% have a cough and rapid breathing, and 23% have a fever. Child mortality among children aged 1-5 years is due to diarrhea (27%), malaria (23%), measles (27%), and respiratory infections (16%). Only 3% of children aged under 5 years has acute malnutrition. One in four are stunted, which reflects prolonged or chronic undernutrition. The total fertility rate is 5.8 children per woman, which is a 10% decrease from 1978. The lowest fertility is among women in the main cities of Yaounde and Douala (4.4 children) and among women with a secondary or higher education (4.5). Over 50% of women have sexual intercourse before the age of 16 years, and 50% are married before the age of 17 years. 50% of married women have their first child at the age of 19 years. Contraceptive usage is 16% among women in any union, of which 25% is use of a modern method. Only 1 in 25 women use an effective method, but this rate is double the rate in 1978. Total fertility would be 10% if unwanted fertility were avoided. Most men and women want large families.

The present inter-University study aims to analyze the vaccine statute of the Belgian French-speaking general practionners and the reasons of their possible non-vaccination. A questionnaire with an exhaustive list of vaccines was sent by postal way to a random sample of thousand two hundred and twenty general practitioners. The results were analyzed via SPSS 13. The rate of answer is 60.83%. Two thirds of the doctors (67%) considered themselves in order of vaccination anti-influenza. A majority of doctors (59.7%) is vaccinated systematically each year. The majority of the doctors (83%) considered themselves in antitetanus order of vaccination. Two thirds (67%) think that the vaccine protects from 5 to 10 years. Nearly 73% of the doctors considered themselves in order of vaccination against hepatitis B. More than 50% of the doctors received a vaccine HBV since less than 10 years. The majority of the doctors (79.2%) made a blood control of their protection after vaccination HBV Almost half of the doctors thinks that the vaccine protect for life, 23% from 10 to 20 years and 14% from 5 to 10 years. Two thirds (67%) of the doctors did not make a vaccine against rubella. In 80% of the cases vaccination dated from more than 20 years. In nearly two thirds of the cases the doctors did not make blood control of their protection. Nearly 60% of the questioned doctors think that vaccination offers a protection to life. About half of the doctors did not consider themselves in order of vaccination against the whooping-cough. In three quarter of the cases last vaccination dated from more than 20 years. The two principal durations of protection of the vaccine are with life and between 10 and 20 years. Three quarters of the questioned doctors are considered in order of vaccination against the poliomyelitis. However in 62% of the cases the last vaccine goes up with more than 20 years. More two thirds of the doctors think than the vaccine protects with life or from 10 to 20 years. Two thirds of doctors considered themselves in order of vaccination against the diphteria. For a third of the doctors the vaccine dated from less than 5 years, in more than one quarter of the cases to more than 20 years like between 5 and 10 years. About half of the doctors said they were vaccinated against other pathologies: hepatitis A (34.5%), the yellow fever (21.1%), the thyphoid fever (12.5%), the BCG (8.9%), the pneumococcus (6.6%), meningitis and variola (5%). In the French Community, the vaccine coverage of the general practitioners against the influenza (67%), tetanus (83%) and hepatitis B (73%) is, in this study, higher or equal to the other Belgian and international studies but remains insufficient. A bad vaccine coverage is observed concerning rubella, the whooping-cough, the poliomyelitis. The answers over the durations of protection of the vaccines are rather disparate and show a bad knowledge of these durations and diagrams of vaccination. An update of this knowledge could be carried out during the continuous medical trainings.

Recent legislative texts have changed vaccinal policy and reinforced the role of midwives in vaccine prevention in perinatal healthcare. Quite as paediatricians and obstetricians-gynecologists, midwives can now prescribe and carry out, for the mothers, vaccines against rubella, tetanus, poliomyelitis, diphtheria, hepatitis B, influenza and whooping-cough and for the newborns vaccines against hepatitis B and tuberculosis. Concerning vaccinations, practitioners have to respect the vaccination calendar and a collaborative action is useful and necessary. These national guidelines are regularly updated when new vaccines and new recommendations come to light, for example for children (papillomavirus, tuberculosis, pneumococcus...), young adults (varicella, whooping-cough) and health professions in contact with very young children (varicella, measles, influenza and whooping-cough). The recent changes in tuberculosis prevention from routine vaccination of all newborn infants to selective vaccination lead to reinforce measures to detect the infants at higher risk, for them to be vaccinated before discharge at home. Midwives and nurses occupy a central place in family policy and become, with obstetricians-gynecologists and pediatricians, key actors for the effectiveness and the success of vaccine strategies in perinatal health.

Timely vaccinations of children in developing countries are important for reducing morbidity and mortality, which are Millennium Development Goals. However, a majority of children do not possess vaccination cards compiling information on timing. We investigated the benefits of vaccination cards for the uptake of immunizations against diphtheria, pertussis and tetanus (DPT), polio, tuberculosis (BCG), and measles using data on over 200,000 Indian children from the District Level Health and Facility Survey 3. Methodological issues such as whether parents of children with higher morbidity levels may have them vaccinated were investigated. The results from the models for DPT, polio, measles, and BCG vaccinations showed significant beneficial effects of maternal education, household possessions, and access to health care facilities. Moreover, models for children's ages at the time of vaccination showed significant interactions between maternal education and access to and availability of health care facilities. Finally, models for child morbidity due to diarrhea, cough, and fever showed that timely vaccinations against DPT, access to piped water, and cooking with electricity or natural gas were associated with lower morbidity. Overall, issuing paper or electronic vaccination cards to children is likely to enhance timely uptake of various immunizations thereby reducing child morbidity.
