Bridging the gap: how traditional healers interact with their patients. A comparative study in Cameroon

Objective To compare traditional healers (TH) and Cameroonian representatives of Western medicine (Western providers (WP)) in terms of patient characteristics and communication patterns during the consultation in rural Cameroon. Methods A facility‐based comparative study was conducted. Seven TH were compared to eight WP in the same district. Patients (five per provider) provided detailed socio‐demographic data. Recorded consultations were analysed with the Roter Interaction Analysis System (RIAS). Results Patients were similar in socio‐demographic characteristics except for age, where TH patients were on average 9 years younger (P < 0.05). Patients of TH travelled 2.5 times as far to their provider as did patients in the WP group (79 vs. 31 km; P < 0.05) and paid 12 times more for their treatment (123 vs. 10 Euros; P < 0.05). Consultations of TH were shorter (5.6 vs. 10.3 min, P < 0.01), had fewer utterances (100 vs. 166, P < 0.05) and the patient’s share in the communication was smaller (P < 0.01). TH had a higher percentage of lifestyle and psychosocial information at the expense of medical information (P < 0.05) and communicated more emotionally (P < 0.001). They asked more frequently for their patients’ opinion (P < 0.01) and explicitly discussed their patients’ concept of illness (P < 0.001). Patients of TH responded with a higher percentage of active communication (P < 0.05) i.e. question asking (P < 0.01). Conclusions Our data contradict the idea that the lack of money or geographical access to Western health care in rural Africa is the main reason for people to consult traditional healers. Compared to WP, TH interacted very differently with their clients, using a more patient‐centred communication style, to seek common ground with patients. This different type of interaction could be a relevant factor contributing to the popularity of traditional healers in Cameroon.     

Provider–patient interaction in rural Cameroon—How it relates to the patient's understanding of diagnosis and prescribed drugs,the patient's concept of illness,and access to therapy

Objective

This cross-sectional survey examines the relation between provider–patient interaction and several patient-outcomes in a rural health district in Cameroon.

Methods

We used structured patient interviews and the Roter Interaction Analysis System (RIAS) for analysis of audio-recorded consultations.

Results

Data from 130 primary care consultations with 13 health-care providers were analysed. 51% of patients correctly named their diagnoses after the consultation; in 47% of prescribed drugs patients explained correctly the purpose. Patients’ ability to recall diagnoses was related to the extent of clarity a provider used in mentioning it during consultation (recall rates: 87.5% if mentioned explicitly, 56.7% if mentioned indirectly and 19.2% if not mentioned at all; p < 0.001). Two thirds of patients were able to describe their concept of illness before the consultation, but only 47% of them mentioned it during consultations. On average patients who mentioned their disease concept were faced with more remarks of disapproval from providers (1.73 vs 0.63 per consultation; p < 0.01). Although 41% of patients admitted problems with financial resources to buy prescribed drugs, discussion about financial issues was very rare during consultations. Providers issued financial questions in 32%, patients in 21% of consultations.

Conclusion

This study shows that provider–patient interaction in primary health care in a rural Cameroon district deserves more attention. It might improve the patients’ knowledge about their health condition and support them in beneficial health behaviour.

Practice implications

Our findings should encourage providers to give more medical explanation, to discuss patients’ health beliefs in a non-judgemental manner, and to consider financial issues more carefully.     

The male–female gap in physician earnings: evidence from a public health insurance system

Empirical evidence from US studies suggests that female physicians earn less than their male counterparts, on average. The earnings gap does not disappear when individual and market characteristics are controlled for. This paper investigates whether a gender earnings difference can also be observed in a health‐care system predominantly financed by public insurance companies. Using a unique data set of physicians' earnings recorded by a public social security agency in an Austrian province between 2000 and 2004, we find a gender gap in average earnings of about 32%. A substantial share of this gap (20–47%) cannot be explained by individual and market characteristics, leaving labor market discrimination as one possible explanation for the observed gender earnings difference of physicians.

Paediatric rehabilitation

More and more researchers are questioning the theoretical and scientific foundations as well as the efficacy and effects of many physiotherapy interventions. The same applies for many of the neurophysiological based interventions that are being used in paediatric rehabilitation. Opinions and views regarding the development of motor behaviour of infants and children are significantly changing. Paediatric interventionists should consider bringing their interventions and focus of treatment into agreement with changed scientific knowledge. Moreover, for almost all other medical problems in childhood, paediatric rehabilitation has little to offer but mostly miniaturized forms of adult treatment. It not only means that we have to make a paradigm shift, but also are in the need of a broader view on paediatric rehabilitation as a specialized professional activity.     

Value of urethral pressure profilometry in the female incontinent patient: a prospective trial with an 8-channel urethral catheter

Objectives. To measure the pressure profiles at different positions of the urethral circumference simultaneously.Methods. Twenty-two women with symptoms of genuine stress incontinence underwent urogynecologic assessment and multichannel urethral pressure profilometry (UPP) at rest with a specially designed 8-channel urethral catheter with radial openings.Results. The distribution pattern of maximum urethral closure pressure (MUCP) and functional urethral length (FUL) values were significantly different (P = 0.004 and P = 0.0004, respectively). Most of the highest MUCP values per patient were found between channels 2 and 4 (P = 0.015); most of the greatest FUL values per patient were found between channels 3 and 4 (P = 0.15).Conclusions. The data of our study substantiate asymmetric radial pressure distribution within the urethra and underline the necessity of cautious interpretation of results of conventional single-channel UPP, which might vary because of transducer orientation.     

Optic disc haemorrhages and vascular abnormalities in a glaucoma population

Purpose: To retrospectively examine the optic disc photographs of a glaucoma population for optic disc haemorrhages, vascular occlusions and vascular abnormalities. Methods: The optic disc photographs of 906 eyes of glaucoma and suspect glaucoma patients were examined. Optic disc photographs were taken annually, where possible, with the follow-up period varying between 1 and 14 years duration (mean, 2.89). Glaucoma patients are regularly reviewed every 4–6 months and glaucoma suspects every 1–2 years, depending on the ophthalmologist. Low-tension glaucoma patients were reviewed more frequently (mean, every 2.6 months). The results of the findings were compared to a control group of 39 subjects with a mean follow-up period of 7 years, using Fisher's exact test. Results: It was found that during the period under review, 7.4% (n= 67) of eyes had optic disc haemorrhages. The highest frequency of optic disc haemorrhages (37.5%) was found in the low tension glaucoma group (P= 0.0001) followed by 11.4% of primary open-angle glaucoma eyes (P= 0.03). In the normal group there were three eyes with optic disc haemorrhages and one with a disc collateral, which constitutes 5.1% vascular changes in this sub-group. Of the study eyes 2.8% had central retinal vein occlusions, 1.3% branch vein occlusion, 1.2% disc vessel abnormalities (loops) and 1.1% disc collaterals. Discrete nerve fibre layer haemorrhages and microaneurysms were found in 0.8% and 1.8% of eyes, respectively. Conclusions: A total of 16.8% of the eyes observed in this study had either disc haemorrhages or vascular changes. The underlying trend of vascular and haemorrhagic changes in glaucoma are demonstrated in this sample, which is in general agreement with previous studies. The high percentage of optic disc haemorrhages in low tension glaucoma is highlighted. The presence of microaneurysms and nerve fibre layer haemorrhages is interesting but of unknown significance.     

The Dutch version of the self-report Child Activity and Limitations Interview in adolescents with chronic pain

Purpose: To assess the factor structure, related constructs and internal consistency of the Child Activity Limitation Interview 21-Child version for use in Dutch-language countries.

Methods: Cross-sectional validation study: After forward and back translation of the Dutch version of the Child Activity Limitation Interview 21-Child adolescents (11–21 years old) with chronic musculoskeletal pain completed an assessment. The assessment contained the Dutch Child Activity Limitation Interview, and questionnaires about demographics, pain intensity, functional disability, anxiety and depression. Internal consistency and construct validity were evaluated through exploratory factor analysis (principal axis factoring with oblique rotation) and hypotheses testing using pain intensity, activity limitations, anxiety and depression as comparative constructs.

Results: Seventy-four adolescents completed the assessment. Exploratory factor analysis resulted in a two-factor structure, explaining 50% of the variance. Internal consistency was good (Cronbach’s α?=?0.91 total scale, α?=?0.90 Factor 1, α?=?0.80 Factor 2). All nine hypotheses were confirmed.

Conclusion: The Dutch version can be used to assess pain-related disability in Dutch-speaking adolescents comparable to the study sample. Scores on both subscales provide insight into the severity of the pain-related disability in both daily routine and more physically vigorous activities.

• Implications for Rehabilitation

• Chronic pain is a disabling disorder which not only impacts physically but restricts quality of life.

• This study provides clinicians a questionnaire to measure pain-related disability and quantify the impact of pain on the daily living of adolescents.

• The advantage of the Dutch version of the Child Activity and Limitations Interview over other measurements is that it can distinguish limitations in daily activities from more physically vigorous activities.

     

Association of pupillary parasympathetic hyperreflexia and systemic inflammation in patients with systemic lupus erythematosus

In chronic inflammatory diseases, cytokines stimulate the hypothalamus pituitary adrenal axis and the hypothalamus autonomic nervous system (HANS) axis. The present study was performed to find autonomic nervous function parameters in patients with systemic lupus erythematosus (SLE) which are suitable to demonstrate the activation of the HANS axis during systemic inflammation. Thirty-four patients with SLE (age 35.3 +/- 1.9 yr) were investigated by seven standardized autonomic nervous function tests. The SLEDAI and laboratory parameters of systemic inflammation were assessed by standard techniques. Pupillary latency time hyperreflexia was found in 29.4%, whereas maximal pupillary area was hyperresponsive in only 2.9%. A total of 12% had overall cardiovascular autonomic nervous hyperreflexia. Patients with latency time hyperreflexia had more severe systemic inflammation [erythrocyte sedimentation rate (ESR): P < 0.001; C-reactive protein (CRP): P = 0.0094; fibrinogen: P < 0.001; albumin: P = 0.003; antinuclear antibodies: P = 0.020]. The longitudinal study of 13 patients during 4 yr demonstrated a parallel increase and decrease in latency time percentile and ESR. SLE patients with increased systemic inflammation had an activated HANS axis which can be measured by a parasympathetic pupillary reflex test.      

Elevation of serum cystathionine levels in patients with cobalamin and folate deficiency

Homocysteine can be methylated to form methionine by the cobalamin- (Cbl) and folate-dependent enzyme, methionine synthase; serum levels of total homocysteine are elevated in greater than 95% of patients with either Cbl or folate deficiency. Homocysteine can also condense with serine to form cystathionine in a pyridoxal phosphate-dependent reaction catalyzed by cystathionine beta-synthase. Cystathionine is subsequently cleaved to cysteine and alpha-ketobutyrate by the pyridoxal phosphate-dependent enzyme gamma-cystathionase. To assess levels of cystathionine in Cbl and folate deficiency, we developed a new capillary gas chromatographic-mass spectrometric assay and measured cystathionine in the serum of normal subjects and patients with clinically confirmed deficiencies of these vitamins. The normal range for serum cystathionine was 65 to 301 nmol/L (median = 126 nmol/L) for 50 normal blood donors. In 30 patients with clinically confirmed Cbl deficiency, values for cystathionine ranged from 208 nmol/L to 2,920 nmol/L (median = 816 nmol/L) and 26 (87%) had levels above the normal range. In 20 patients with clinically confirmed folate deficiency, cystathionine concentrations ranged from 138 nmol/L to 4,150 nmol/L (median = 1,560 nmol/L) and 19 (95%) had values above the normal range. Five homozygotes for cystathionine beta-synthase deficiency had high values for serum-total homocysteine and low or low-normal values for serum cystathionine that ranged from 30 nmol/L to 114 nmol/L even though they were on treatment with pyridoxine and had partially responded. One patient with a defect in the synthesis of 5-CH3- tetrahydrofolate and five patients with defects in the synthesis of CH3- Cbl had high values for serum-total homocysteine and high values for cystathionine that ranged from 311 nmol/L to 1,500 nmol/L even though they were on treatment with folic acid and Cbl, respectively, and had partially responded. We conclude that levels of cystathionine are evaluated in the serum of most patients with Cbl and folate deficiency and that they are useful in the differential diagnosis of an elevated serum-total homocysteine level.
