Access to complementary medicine via general practice

BACKGROUND

The popularity of complementary medicine continues to be asserted by the professional associations and umbrella organisations of these therapies. Within conventional medicine there are also signs that attitudes towards some of the complementary therapies are changing.

AIM

To describe the scale and scope of access to complementary therapies (acupuncture, chiropractic, homoeopathy, hypnotherapy, medical herbalism, and osteopathy) via general practice in England.

DESIGN OF STUDY

A postal questionnaire sent to 1226 individual general practitioners (GPs) in a random cluster sample of GP partnerships in England. GPs received up to three reminders.

SETTING

One in eight (1226) GP partnerships in England in 1995.

METHOD

Postal questionnaire to assess estimates of the number of practices offering 'in-house' access to a range of complementary therapies or making National Health Service (NHS) referrals outside the practice; sources of funding for provision and variations by practice characteristics.

RESULTS

A total of 964 GPs replied (78.6%). Of these, 760 provided detailed information. An estimated 39.5% (95% CI = 35%-43%) of GP partnerships in England provided access to some form of complementary therapy for their NHS patients. If all non-responding partnerships are assumed to be non-providers, the lowest possible estimate is 30.3%. An estimated 21.4% (95% CI = 19%-24%) were offering access via the provision of treatment by a member of the primary health care team, 6.1% (95% CI = 2%-10%) employed an 'independent' complementary therapist, and an estimated 24.6% of partnerships (95% CI = 21%-28%) had made NHS referrals for complementary therapies. The reported volume of provision within any individual service tended to be low. Acupuncture and homoeopathy were the most commonly available therapies. Patients made some payment for 25% of practice-based provision. Former fundholding practices were significantly more likely to offer complementary therapies than non-fundholding practices, (45% versus 36%, P = 0.02). Fundholding did not affect the range of therapies offered, and patients from former fundholding practices were no more likely to pay for treatment.

CONCLUSION

Access to complementary health care for NHS patients was widespread in English general practices in 1995. This data suggests that a limited range of complementary therapies were acceptable to a large proportion of GPs. Fundholding clearly provided a mechanism for the provision of complementary therapies in primary care. Patterns of provision are likely to alter with the demise of fundholding and existing provision may significantly reduce unless the Primary Care Groups or Primary Care Trusts are prepared to support the 'levelling up' of some services.

Intravesical bacillus Calmette-Guerin and dimethyl sulfoxide for treatment of classic and nonulcer interstitial cystitis: a prospective, randomized double-blind study

PURPOSE

We conducted a prospective, double-blind study with a crossover design of intravesical bacillus Calmette-Guerin (BCG) and dimethyl sulfoxide to determine whether patients with classic and nonulcer interstitial cystitis, respectively, might benefit from either regimen.

MATERIALS AND METHODS

A total of 21 patients, including 11 with classic and 10 with nonulcer interstitial cystitis, randomly underwent treatments with intravesical BCG or dimethyl sulfoxide and, if not improved, were treated with the other substance after a washout period. All 21 patients were evaluated with symptom questionnaires, including a visual analog pain scale and voiding diaries.

RESULTS

Regardless of regimen, there was no improvement in maximal functional capacity. There was a reduction in urinary frequency following dimethyl sulfoxide treatment but only in the classic subtype (p <0.05), whereas no reduction was seen following BCG in either subtype. A substantial pain decrease was noted in classic (p <0.05) as well as nonulcer (p <0.05) interstitial cystitis following dimethyl sulfoxide.

CONCLUSIONS

Intravesical BCG has been presented as a promising new option for treatment of interstitial cystitis. We failed to demonstrate benefit from this treatment. Dimethyl sulfoxide had no positive effect on maximal functional capacity but resulted in a significant reduction in pain and urinary frequency, although only in patients with classic interstitial cystitis.

[Contamination by aflatoxins of local peanut oils prepared in Senegal]

Aflatoxins are mycotoxins produced by certain strains of fungus (Aspergillus) which develop in peanut seeds. Peanut oil and peanut meal are widely used in Senegal. The risk of intoxication is quite real. We determined aflatoxin contamination levels in peanut oil and food prepared by small scale production plants in the Kaolack and Diourbel regions of Senegal. High performance liquid chromatography (HPLC) of the different samples showed that 80% of them were contaminated. Aflatoxin B(1), B(2), G(1) and G(2) were detected. The pattern of contamination was similar for the two regions. Aflatoxin B(1) was prevalent and found in over 85% of the samples. The mean content of this mycotoxin (the most dangerous toxin) was about 40 ppb, a value which largely exceeds specifications for allowable levels.

First Scandinavian experience of electrical sacral nerve stimulation in the treatment of the overactive bladder

OBJECTIVE

This study aimed to evaluate the efficacy of electrical sacral nerve stimulation (SNS) in the treatment of urinary incontinence and urinary retention refractory to conservative treatment, and to assess the impact of urodynamic abnormalities and electrode position.

MATERIAL AND METHODS

Thirty patients (10 men, 20 women) with a mean age of 59 years (range 21-79 years), all of whom had longstanding symptoms ranging from 2 to 46 years (mean 12.4 years), were subjected to a percutaneous test stimulation. Ten patients responded well, resulting in a permanent implant in nine patients. Electrode positions were determined by plain X-ray and computed tomography.

RESULTS

Radiologically, a variety of positions of the temporary electrodes was seen. In the implanted patients, long-term symptom reduction varied over time, ranging from total relief to partial or total recurrence of symptoms.

CONCLUSIONS

SNS is a new promising option for the treatment of urge incontinence. Refined instruments for proper patient selection and the optimal way to position the electrode remain to be developed.

Maximal functional electrical stimulation in routine practice

Maximal functional electrical stimulation is now an established treatment for urgency and urge incontinence. Many studies have been presented with good and consistent results. In a number of prospective studies we have previously recorded very favourable effects in stress incontinence and urge incontinence. In the present study, we have compared our previous experience with a retrospective analysis of a series of maximal functional electrical stimulation given according to a simple routine protocol and including 84 patients. The overall subjective improvement rate was 54% but the cure rate was only 5%, which is far below our experience in previous studies, as well as in others. The subjective outcome was in agreement with changes in mictrurition variables as recorded in voiding diaries. The discrepancy probably depends on a number of factors. It is suggested that the most crucial ones are patient selection, the intensity of stimulation, and the number of sessions given. It is important to realize the limitations and pitfalls of the technique when it is applied in routine practice.

Home uroflowmetry: improved accuracy in outflow assessment

To study home uroflowmetry and to compare this method to free or "traditional" uroflowmetry in the evaluation of the patient with symptomatic benign prostatic hyperplasia (BPH), and the relationship between the values of home uroflowmetry parameters and bladder outlet obstruction (BOO). Twenty-five patients (mean age, 67 years) with symptomatic BPH were examined with home uroflowmetry, free uroflowmetry, and pressure-flow measurement. The patients were assessed using the International Prostate Symptom score; digital rectal examination; routine blood chemistry, including serum prostate-specific antigen level; urinanalysis; transrectal ultrasonography; and post-void residual urine. The 24 hr were divided into "active time" (AT) and "sleep time" (ST). AT home uroflowmetry parameters were compared to ST ones. The home uroflowmetry parameters were compared to respective ones of the free uroflowmetry as well and those obtained by pressure-flow measurement. The patients were asked about their opinion of home uroflowmetry. Home uroflowmetry was found to be a simpler and more acceptable method than free uroflowmetry. The mean Qmax of AT was significantly greater than the mean Qmax of ST, but the mean voided volume and mean voiding time of ST were significantly larger than those of AT. There was a close relationship between the mean Qmax at home and the Qmax in hospital, but the voided volume and voiding time measured in hospital were significantly larger than those at home. Home uroflowmetry provided an estimation of BOO for 46% of the patients as low if the home mean Qmax was >14 ml/sec, and as high if the home mean Qmax was <10 ml/sec. Home uroflowmetry was well accepted by the patients and gave more information than free uroflowmetry. In 46% of the cases, an estimation of BOO was obtained with home uroflowmetry.

[Staphylococcus aureus purulent pleurisy in children. Experience of the Albert Royer Hospital for Children of the Fann University Hospital Center in Dakar]

The authors report here by a retrospective study 58 cases of Staphylococcus aureus empyema at Albert ROYER child hospital located in the Fann University Teaching Hospital of Fann between January 1st 1992 and December 31, 1995. In this study staphylococcus aureus is the bacterium involved in pleural effusions of the children (54%) a long way ahead Streptococcus pneumoniae (16%). Infant less than 30 month is more affected (86%). The average age of the patients is 16.8 month +/- 16.6. The resistance of the germ to usual antibiotics, the precariousness of the research field and mechanical complications linked to the outpouring explain their seriousness. The treatment lies upon an adapted antibiotic and bactericidal therapy associated to closed chest tube drainage.

[Well water pollution in the Khombole district: research on the contamination by organochlorine pesticide residues and organic substances (feces)]

The study realized in the district of Khombole (SENEGAL) has permit to estimate the contamination levels of wells waters used by the populations. The research and the dosage of the organichlorine pesticide residues, nitrites and nitrates and microbiologic analysis have been done on 19 wells chosen after a drawning of lots. The organochlorine pesticide residues which have been found prove that the wells are permanently exposed to these chemical substances which don't constitute nevertheless a major risk for the populations health. The results of our research proved also that there is a real risk of intoxication with the nitrogen oxides. In effects more than 50% of the wells have revealed nitrates contents up to the indicative value (25 mg/l). As for the nitrates, with a few exceptions (5/18), the contents are superior to the authorized norm (0.1 mg/l). By another way the bacteriologic analysis has revealed in the one hand a DBT (Total Bacterian Count) up to 10,000 germs/l for all the wells, and in the other hand the presence of Escherichia coli, Enterococcus faecalis that confirm a faecal contamination.

[Risk factors for low birth weight: influence of maternal age, parity, gestational age, nutritional status and maternal pathology]

A retrospective study carried on between april 1st and september 31st 1997 has helped in collecting. 69 cases of low birth weight new-born (weight < 2500 g) at Abass Ndao hospital center in Dakar. The above population has been compared to 79 eutrophic new-born of mean birth weight equal to 3047.7 +/- 311 g (witnesses). The goal of this study is to appreciate the relationship between the maternal age, the number of the gestation, the parity, the nutritional status, the maternal pathologies during pregnancy and the low weight at birth. There was no difference between both groups as regards to the mean age (p = 0.44), the mean number of gestation (p = 0.7) and the mean parity (p = 0.48). On the other hand, the weight of the mother is smaller as for the group of low birth weight but the mean body mass index stand at normal in both groups. The pathologies during pregnancy period were obviously more frequent in the group of low birth weight new-born. There is a real need to insist on the preventive measures to be taken and the treatment of the maternal pathologies during pregnancy.

Photophysical properties of sexi(3-methoxythiophene): evidence for energy migration in a conducting oligomer, based on fluorescence quenching

The electronic absorption and fluorescence excitation and emission spectra of poly(3-methoxythiophene) (PMOT), a soluble, electroactive oligomer mainly constituted of hexamer, were investigated in dimethylsulfoxide at room temperature. The study of PMOT photophysical properties suggests the existence of important pi-electronic delocalization in the oxidized and reduced form of the oligomer. A significant fluorescence quenching of PMOT takes place in the presence of various quenchers such as dimethylterephthalate, potassium iodide and thallium acetate. Quenching mechanisms implying a quencher-induced intersystem-crossing step are proposed. Modified Stern-Volmer relationships were obtained with large quenching bimolecular rate constants (2.7 x 10(9)-6.1 x 10(11) l mol(-1) s(-1)), which suggests electronic energy migration throughout the repeat units of the PMOT hexamer.

Treatment guidelines for classic and non-ulcer interstitial cystitis

Interstitial cystitis (IC) is a chronic disease of as yet unknown etiology. It commonly affects females, presenting with symptoms of pain on bladder filling, and urinary frequency. Accumulated evidence indicates that IC is a heterogeneous syndrome. Compared to classic IC, the non-ulcer type appears different concerning symptomatic, endoscopic and histological findings, as well as the response to various forms of treatment. This review gives an introduction to the syndrome of IC, concerning epidemiology, clinical characteristics, diagnostic criteria and etiological considerations. A variety of treatment modalities have been suggested and are assessed and reviewed, such as hydrodistension of the bladder, intravesical instillation therapy, oral medication, transcutaneous electrical nerve stimulation, transurethral resection of diseased bladder tissue, and supratrigonal cystectomy followed by enterocystoplasty and urinary diversion. Our algorithm on non-surgical and surgical treatment for classic and non-ulcer IC is presented.

Increased tyrosine hydroxylase immunoreactivity in bladder tissue from patients with classic and nonulcer interstitial cystitis

PURPOSE

Interstitial cystitis is a chronic debilitating condition which mainly affects women. Accumulated evidence indicates that interstitial cystitis is a heterogeneous syndrome. The nonulcer subtype appears different than classic interstitial cystitis in regard to symptoms, and endoscopic and histological findings as well as response to various treatments. We further explore the neurogenic nature of this disease using indirect immunofluorescence to evaluate the presence and density of various autonomic and sensory nerve fibers.

MATERIALS AND METHODS

Specimens from the bladder wall of 6 patients with classic interstitial cystitis, 7 with nonulcer interstitial cystitis and 6 controls were evaluated to determine the presence and density of nerve fibers containing tyrosine hydroxylase, calcitonin gene-related peptide, neuropeptide Y and substance P using specific antibodies, and the general presence of nerve fibers using a mixture of antibodies against nerve filament, neuron specific enolase and S-100 protein.

RESULTS

Increased density and number of nerve fibers immunoreactive for tyrosine hydroxylase were noted in interstitial cystitis cases compared to controls. Furthermore, there was a difference between classic and nonulcer disease in the overall density of nerves using the antibody mixture.

CONCLUSIONS

Our findings indicate an altered peripheral sympathetic innervation in interstitial cystitis cases, which may be an indication of primary neurogenic etiology. The difference in nerve density observed after incubation with the antibody mixture between classic and nonulcer interstitial cystitis supports the hypothesis that the 2 forms represent separate entities.

[Empyema caused by Staphylococcus aureus in children: the experience of the Albert Royer Children's Hospital at Fann University Hospital, Dakar]

We report a retrospective study of 58 cases of empyema caused by Staphylococcus aureus at the Albert Royer Children's Hospital at the Fann University Hospital, between January 1st 1992 and December 31st 1995. Staphylococcus aureus is the principal bacterium responsible for pleural effusions in children (54%), way ahead of Streptococcus pneumoniae (19%). Most of the children affected (86%) are less than 30 months old. Theses infections are often serious due to the resistance of the bacterium to the usual antibiotics, the lack of solid research data and mechanical complications associated with the effusion. Treatment is based on the use of an appropriate bactericidal antibiotic treatment and pleural drainage.

Recruitment, distribution and phenotypes of mast cells in interstitial cystitis

PURPOSE

Interstitial cystitis (IC) is a chronic disabling condition of unknown etiology. One of its major characteristics is an increase in mast cells (MC) showing signs of activation. It has been suggested that the proteinase content defines two MC types: MC(TC), containing chymase and tryptase, and MC(T), which contains tryptase but lacks chymase. Here, we investigated the MC distribution and the MC proteinase expression in IC together with the tissue expression of the major MC growth factors, stem cell factor (SCF) and interleukin-6 (IL-6).

MATERIALS AND METHODS

MC were enumerated in bladder specimens from patients with classic IC, nonulcer IC and controls. MC were visualized in terms of metachromasia, reflecting glycosaminoglycan content, and immunohistochemically, visualizing tryptase, chymase and IL-6 as well as the surface markers CD117 and SCF.

RESULTS

Classic IC displayed a 6 to 10-fold increase of MC identified by proteinase content while in nonulcer IC there were twice as many MC as in controls. In contrast to nonulcer IC and controls, classic IC displayed an abundance of epithelial MC. Fewer CD117+ than proteinase+ MC were detected in IC but not in controls. Classic IC coexpressed SCF and IL-6 in the epithelium and displayed numerous SCF and IL-6+ cells in the mucosa and detrusor muscle, many of which were MC.

CONCLUSIONS

Redistribution of MC into the epithelium and a high bladder wall MC density distinguish classic IC from nonulcer IC. Our findings suggest an SCF/IL-6-driven MC response in IC. They also indicate a downregulation of the SCF receptor in IC.

[Infections in Senegalese children and adolescents with sickle cell anemia: epidemiological aspects]

Infection is the main factor of morbidity and mortality in children with sickle cell disease (SCD). The objective of this study is to determine it's epidemiologic outline in senegalese children and adolescents with SCD. We retrospectively studied infection data in all the charts of a cohort of 323 patients with SCD (307 SS, 13 SC and 3 s beta + thalassemia) followed at Albert Royer children hospital from january 1991 to december 1997. Serum sampling was systematically made for HIV and antigen HBs serology in all patients we received in the last 3 months (october to december 1997). Patients were aged from 5 months to 22 years (medium age = 8 years). 813 infection episodes were diagnosed, concerning 184 patients (56 per cent). SS patients were more affected (59 per cent) than the others (23 per cent, p = 0.04). ENT and broncho-pulmonary onsets were more frequent but had a generally benign course. Menigitidis, septicemia and osteomyelitis were exclusively diagnosed in SS patients. Their prevalences in this group were respectively: 1.0 per cent, 4.9 per cent and 9.8 per cent. HIV serology was determined in 155 patients, including 41 per cent with blood transfusion antecedents. All tests were negative. HBs antigen was determined in 104 patients and seroprevalence was 7.7 per cent in the whole group and 6.0 per cent in patients with transfusion antecedents and 7.7 per cent for the others. Plasmodium falciparum malaria onset was observed in 9.6 per cent of our patients and there was no case of cerebral malaria. Infection was involved in 9 of the 11 cases of death. Then infection constitute the major problem in children and adolescents with SCD in Dakar. However prevalences of severe onsets are comparable to data in Europe despite our poor follow up conditions. Senegal haplotype may lead to a good tolerance of SCD. Negative HIV serology and low HBs antigen seroprevalence in transfused patients are attributed to a relatively low level of HIV prevalence in the general population and a good transfusion security in Senegal.

[Protein profile of Senegalese children presenting with nephrotic syndrome]

In Senegal, nephrotic syndrome usually occurs upon malnutrition that confers it its specificity and has brought us to establish the proteinic profile of Senegalese children suffering from it, in the aim to improve its treatment. Twenty children on the average of six years, hospitalized for nephrotic syndrome, were chosen. They were compared to 20 healthy children of the same age group, and 20 other children hospitalized for a non-renal inflammatory syndrome. For each subject were dosed total blood proteins and albumin. The protein electrophoresis has permitted to evaluate the alpha-1, alpha-2, beta and gamma globulins. We have observed predominance of boys with a 2.33 sex ratio. Our patients presenting a nephrotic syndrome were about six years old; no case has been noted before two years. Total proteins and albumin have decreased respectively to 52.10 g/l and 16 g/l. This diminishing is essentially linked to the massive urinary escape of plasmatic proteins and would explain partly the increase of lipids. The alpha-1 globulins were equally lowered but the alpha-2 globulins were increased by 40% of total proteins. Beta globulins have decreased, following the evolution of gamma globulins. In Senegal, The early age of nephrotic syndrome occurrence and the biological perturbations of the proteinic profile, recommend global and quick treatment considering food recovery and nutrition. The correction of these parameters being able to constitute in one hand an element of accessible and reliable supervision, and one the other hand the basis of complete treatment.

[Aflatoxin contamination level in artisanal and industrial peanut butter food in Dakar (Senegal)]

Aflatoxins are mycotoxins produced by some strains of fungus (Aspergillus) which develop in peanut seeds. Peanut oil and past are very used up in Senegal, then the aflatoxin poisoning risk is very actual. The aim of this study was to determinate the aflatoxin level in artisanal and industrial peanut pastry food from Dakar (Sénégal). High Performance Liquid Chromatography (HPLC) analysis of the different samples showed that the most contaminated by aflatoxins are artisanal pastry sold in different market of Dakar (Sénégal). Indeed, 40% of these samples contained mean values of aflatoxin B1 (the most dangerous) widely over allowable EEC specifications (5ppb). Furthermore, most of industrial and domestic peanut pastry were cleaned and could be consumed without risk.

[Protein-energy malnutrition in children less than five years old in a rural zone in Senegal (Khombole)]

A survey on 400 children less than five years old living in three villages of the sanitary district of Khombole has been realized from 17th to 25th April 1997 in order to evaluate the existence of malnutrition and the hazard factor linked to it. All children have been weighed and measured. The paraclinic assessment made up by a rate of haemoglobin and a parasitical test of the, motions have been realized on 275 children. The emaciation concerns 8% of the children and the statural backwardness 34.7% of them. The malnutrition is variable from one village to another. The percentage of children suffering from a severe malnutrition according to the classification of Gomez concerns 4.5%. Geophagy, intestinal parasitosis, and anaemia are closely related to chronic malnutrition. The results show the existence of a precarious nutritional situation in rural area requiring new policies of struggle against malnutrition.
