[Wellbeing and personality pathology in inpatient schematherapy]. / Welbevinden en persoonlijkheidsproblematiek in klinische schematherapie.

BACKGROUND: In treatment of personality disorders, wellbeing is complementary to a focus on reducing symptoms. It is known that symptoms are being reduced and relate to the development of characteristics of personality pathology (schemamodes). AIM: To answer the questions: how does wellbeing develop and how is this development related to the development of schemamodes? METHOD: A naturalistic, prospective, within subjects design was used in the Boerhaven Clinic of Mediant. Respondents received inpatient schema therapy with a focus on symptom reduction as well as increasing functional schema modes and wellbeing. A mixed model analysis was used to assess changes in wellbeing and schema modes at 0, 6, 12 and 18 months. RESULTS: Wellbeing increased significantly during treatment, but declined somewhat at follow-up. A connection was found between increases in wellbeing and increases in functional schema modes and decreases in coping modes. CONCLUSION: Symptoms and wellbeing develop in a different way during and after inpatient schema therapy and they have different relationships with schema modes. A positive psychological approach is recommended besides treatment of symptoms.

Near infrared reactance for the estimation of body fatness in regularly exercising individuals.

Near infrared reactance (NIR) is used to measure body fat percentage (BF%), but there is little data on its use in non-obese, regularly exercising individuals. Therefore, this study aimed to examine the limits of agreement between NIR compared to dual x-ray absorptiometry (DXA) for the measurement of BF% in 2 cohorts of regularly exercising individuals. BF% was measured using DXA and NIR in a regular exercising (≥3 sessions/week), healthy active cohort (HA; n=57), and in a regularly exercising and resistance trained (≥2 sessions/week) cohort (RT; n=59). The RT cohort had lower BF% than the HA cohort (15.3±5.5% and 25.8±7.1%, P<0.001). In the HA and RT cohorts, NIR BF% was associated with DXA BF% (R2=0.72, SEE=3.7, p<0.001 and R2=0.50, SEE=4.1 p<0.001, respectively). In the HA cohort, NIR tended to under-predict BF% (mean difference: - 1.3%; 95% limits of agreement (LOA); - 8.8 to 6.2%) whereas in the RT cohort, NIR tended to over-predict BF% compared to DXA (mean difference: 1.1; 95% LOA; - 8.1 to 10.3%). In conclusion, NIR and DXA yield similar average BF% measurements in 2 cohorts of non-obese regularly exercising individuals. However, the rather broad LOA of NIR need to be considered when using NIR to screen for overweight and obesity, or measure and track changes in body composition.

Predicting leisure participation of school-aged children with cerebral palsy: longitudinal evidence of child, family and environmental factors.

OBJECTIVE: This longitudinal study aims to determine which child, family and environmental variables measured at 2 years of age predict leisure participation in formal and informal activities in school aged children with cerebral palsy (CP). METHODS: Parents of 46 children with CP (mean age at baseline: 2 years 6 months, SD 0 years 1 month; at follow-up 6 years 7 months, SD 0 years 9 months; n = 26 boys, n = 20 girls; Gross Motor Classification System I = 30%, II = 7%, III = 28%, IV = 24%, V = 11%) completed the Children's Assessment of Participation and Enjoyment indicating their child's participation. Multivariate regression models were used to identify early predictors of participation. RESULTS: Movement ability was a significant child-related predictor for formal activities (R(2) 17%, P < 0.05). Movement ability and social skills were most predictive (R(2) 62%, P < 0.00) for informal activities. The feeling of being restricted in family participation was the single most predictive factor for formal and informal activities at family level (R(2) 12%, P < 0.05, R(2) 25%, P < 0.05). Type of daycare was the only environmental variable that was predictive, and only for informal activities (R(2) 16%, P < 0.05). In the overall model movement ability was most predictive for leisure participation in formal activities (R(2) 17%, P < 0.05). Movement ability and social skills are the most important predictors for informal leisure participation (R(2) 62%, P < 0.01). CONCLUSIONS: Several variables are found to be related to formal and informal participation at age 6. Movement ability and social skills at age 2 are most predictive of leisure participation when the child is 6 years old.

Mite and cockroach sensitisation in patients with allergic rhinitis in the Free State.

BACKGROUND: Studies in patients with allergic rhinitis living in the Free State have showed grass pollens to be the predominant allergens, with house-dust mite sensitisation being less prevalent than in the coastal areas and a low rate of sensitisation to the storage mite Lepidoglyphus destructor. No studies have been conducted on sensitisation to the other storage mites, spider mites or cockroaches. We aimed to determine the prevalence of sensitisation to various house-dust mites, storage mites, spider mites and cockroaches in patients with allergic rhinitis living in the Free State. METHODS: Fifty consecutive patients with allergic rhinitis attending the ear, nose and throat clinic at Universitas Hospital underwent skin-prick testing and/or ImmunoCAP RAST testing for common aero-allergens, house-dust mites, storage mites, spider mites and cockroaches. RESULTS: Forty-six per cent of patients were sensitised to one of the house-dust mites, with house mite sensitisation being significantly more common in patients who had previously lived at the coast. Storage mites were not common aero-allergens, while 46% of patients were sensitised to the spider mite Tetranychus urticae. Blatella germanica was the cockroach species to which patients were most commonly found to be sensitised on ImmunoCAP RAST testing, with 38% of patients being sensitised to this aero-allergen. CONCLUSIONS: House-dust mites, T. urticae and the cockroach B. germanica appear to be important aero-allergens in the Free State. Storage mite sensitisation is not common.

Low dose radiotherapy for adenotonsillar lymphoid hyperplasia in HIV-positive patients.

Lymphoid hyperplasia is common in HIV positive patients. The aim of this study was to determine the response to radiotherapy. Thirty-three adult patients with recurrent tonsillitis or upper airway obstruction due to tonsillar hyperplasia and conformed histology of follicular hyperplasia were included. Thirteen underwent a 24 Gy course of radiotherapy and were followed up for a minimum of 16 weeks post-radiotherapy. There was a statistically significant decrease in the median tonsillar size (95% confidence interval [-3;-2]) and in the median CD4 count (95% CI [3;152]) after 16 weeks. None of the patients had acute tonsillitis or airway obstruction after radiotherapy. Low dose radiotherapy is effective in the management of adenotonsillar hyperplasia in HIV positive patients.

Visual stimulus deprivation and manipulation of auditory timing signals on pacing strategy.

In this study the effect of complete visual stimulus deprivation and manipulation of auditory timing signals during this deprivation on pacing strategy during an exercise bout were examined. 7 moderately trained men completed four 40-km cycling time trials under laboratory conditions in either normal light or absolute darkness, with either correct or manipulated auditory timing signals and without any other timing cues. The subjects were told to perform the time trial in the fastest time possible. There was no significant difference among trials for time to perform the trial, power output, heart rate, or ratings of perceived exertion, indicating that brain-control mechanisms responsible for pacing are not affected by manipulation of light or auditory signals.

[Colostomy as a cause of deviation colitis in a blind-ended bowel segment]. / Colostoma als aanleiding voor deviatiecolitis in het blind eindigende darmsegment.

Two women aged 63 and 53 who had undergone colostomy for faecal incontinence, presented a few months later complaining of anal blood and mucous loss. On sigmoidoscopy, a previously healthy section of colorectum seemed to be inflamed. Local treatment with hydrocortisone and mesalazine and oral prednisolone did not relieve the symptoms. Subsequently the affected part of the colon was resected upon which the anal blood and mucous loss stopped. After a deviating stoma procedure, the colonic segment diverted from the faecal stream can develop signs of non-specific inflammation. The risk of colitis following the creation of a stoma is 0-50%. On systematic endoscopy 3-36 months following deviation, the risk of findings corresponding to deviation colitis is 50-100%. Symptoms are usually mild but can be so devastating that continuity of the faecal stream has to be restored or further resection is warranted.

Non-compliance with the re-excision guidelines for cutaneous melanoma in The Netherlands does not influence survival.

AIM: To evaluate causes and consequences of not adhering to the clinical practice guideline for cutaneous malignant melanoma. METHODS: We conducted a retrospective cohort study of the clinical records of 454 subjects whose pathological reports were obtained from a population-based cancer registry to assess determinants and effects of non-compliance of physicians with the excision policy and the related clinical practice guideline for patients with primary localized cutaneous malignant melanoma (CMM). A comparative analysis was performed of patients who did and did not undergo re-excision (compliance versus non-compliance with the guideline). Subjects diagnosed in 1988, 1993 and 1997, just 1 year after publication of the (adapted) guideline, were followed until death due to any cause or until July 1st 2003. RESULTS: Old age was the most important determinant of non-compliance. After adjusting for age at diagnosis, gender, subsite and Breslow thickness there was no significant difference in overall survival between the compliance group and the non-compliance group. CONCLUSIONS: Non-compliance to the guideline is more common in older patients and in patients with melanoma in the head and neck region. After adjusting for confounders, a significant effect of complying with the guidelines on overall survival could not be observed.

Pulmonary hypertension due to recurrent juvenile laryngeal papillomatosis.

Although pulmonary hypertension secondary to upper airway obstruction caused by adenotonsillar hyperplasia has been well described, the association between laryngeal papillomatosis and pulmonary hypertension has not previously been documented. We report three patients with pulmonary hypertension due to upper airway obstruction caused by laryngeal papillomatosis. Pulmonary hypertension can contribute to significant preoperative and postoperative morbidity and cause intraoperative complications. Preoperative diagnosis and treatment of pulmonary hypertension is therefore essential in these patients.

Use and care of an endotracheal/tracheostomy tube cuff--are intensive care unit staff adequately informed?

BACKGROUND: There is an apparent high incidence of tracheal stenosis in the Bloemfontein area. The aim of this study was to determine intensive care unit (ICU) staff knowledge of the use and care of endotracheal and tracheostomy tube cuffs. METHODS: One hundred and twelve qualified nurses, working in 11 different ICUs, were asked to complete an anonymous questionnaire regarding endotracheal/tracheostomy tube cuffs. RESULTS: The results highlight the following three areas of concern: (i) there was an overall misconception in 38% of the respondents that the function of the cuff was to secure the tube in position in the trachea to prevent self-extubation; (ii) accurate regulation of cuff pressure was not routine practice in any of the ICUs; and (iii) only half of the respondents felt their training regarding cuff care management was sufficient. CONCLUSIONS: ICU staff had misconceptions regarding the function and care of endotracheal/tracheostomy tube cuffs. The concept of a higher cuff pressure for better stabilisation of the tube is probably an important factor that could have caused the increase in tracheal stenosis in the Bloemfontein area. Critical care nursing needs to emphasise the use of current techniques, discourage routine cuff deflation, and encourage collaboration with ICU physicians on standards of care. A protocol that could be used in the ICUs regarding the use and care of an endotracheal/tracheostomy tube cuff is proposed.

Incidence and management of acoustic neuromas in South Africa.

OBJECTIVES: To determine the extent to which the various treatment modalities are used in the management of acoustic neuromas treated in South Africa and to estimate the incidence of acoustic neuromas in South Africa. METHODS: A telephonic survey was conducted of all otorhinolaryngologists, neurosurgeons, and radiotherapy centers in South Africa to determine whether they had treated any patients with acoustic neuromas during the calendar year 2000. RESULTS: One hundred and fifteen patients with acoustic neuromas were treated in South Africa during the calendar year 2000, and 8 patients were referred to other countries for treatment. This resulted in an incidence of approximately 0.3 per 100,000 population per year. There was a marked difference in the incidence between the various racial groups: the incidence was at least 1.76 per 100,000 population per year among whites and at least 0.01 per 100,000 population per year among blacks. Of the 115 patients, 78 (68%) were treated surgically and 24 (21%) by stereotactic radiotherapy. Fourteen (12%) patients had newly diagnosed acoustic neuromas that were managed conservatively in the year concerned. The surgical approach used was middle fossa in 8 (7%) patients, retrosigmoid in 61 (53%) patients, and translabyrinthine in 9 (8%) patients. CONCLUSIONS: The majority of acoustic neuromas in South Africa were treated surgically, mainly by a retrosigmoid approach. The incidence of acoustic neuromas in South Africa was approximately 0.3 per 100000 population per year. There were significant racial differences in the incidence.

[Melanoma of the skin: excision policy and pathology report writing in the 'Integraal Kankercentrum Zuid' region is in accordance with the guideline in slightly more than half of the patients]. / Melanoom van de huid: excisiebeleid en pathologieverslaglegging in de regio van het Integraal Kankercentrum Zuid bij iets meer dan de helft van de patiënten volgens de richtlijn.

OBJECTIVE: To determine the extent to which the guidelines for cutaneous melanoma had been implemented in the diagnostic and treatment approach of general hospitals. DESIGN: Retrospective, descriptive. METHOD: Patients were selected via the cancer registration system of the 'Integraal Kankercentrum Zuid' (Integral Cancer Centre South, the Netherlands). They were submitted through the pathology laboratory by 1 of the 16 general hospitals in the region. Data was collected from the pathology (PA) reports of the 573 patients for whom a cutaneous melanoma was diagnosed in 1988, 1993 and 1997. The treatment policy and the PA reports were compared with the recommendations in the guidelines concerned and the revised versions of these published in 1985, 1990 and 1997. The patients studied were 212 men (37%) and 361 women (63%) with an average age of 51 years (range 13-96). RESULTS: A diagnostic excision was performed in 485/573 patients (85%). Invasiveness was assessed in 99% of the preparations; in 14% a melanoma was encountered in situ. Invasive melanomas were less often seen in the head and neck region than on the trunk or limb. Thickness of the tumour was not determined in 8% of all 493 invasive tumours and in 19% the pathology report did not state whether the diagnostic biopsy was performed radically. In accordance with the guidelines, diagnostic excision biopsy was first performed in 59% of patients with a subsequent re-excision if necessary; 77% of the PA reports satisfied the fundamental recommendations from the guidelines. For 55% of the patients the diagnostic and therapeutic procedures as well as the pathology report were completed in accordance with the guideline recommendations. Modest improvement occurred over time. CONCLUSION: The excision and re-excision policies as well as the pathology report writing concurred with the recommendations in the consensus for cutaneous melanoma in slightly more than half of the patients who were diagnosed within the IKZ region in the years 1988, 1993 and 1997.

Colectomy for slow-transit constipation: preoperative functional evaluation is important but not a guarantee for a successful outcome.

PURPOSE: This study was designed to assess the results of preoperative functional evaluation of patients with severe slow-transit constipation in relation to functional outcome. METHODS: Four hundred thirty-nine patients with chronic intractable constipation were evaluated by marker studies. Twenty-one patients underwent colectomy and ileorectal anastomosis for slow-transit constipation. Mean colorectal transit time was 156 hours (normal, <45 hours). Small-bowel transit time was normal in ten patients and delayed in five patients. Six were nonresponders. Morbidity was 33 percent. Small-bowel obstruction occurred in six patients; relaparotomy was done in four patients. Follow-up varied from 14 to 153 (mean, 62) months. RESULTS: After three months, defecation frequency was increased in all. Mean stool frequency improved from one bowel movement per 5.9 days to 2.8 times per day. Sixteen patients felt improved after surgery. Seventeen continued to experience abdominal pain, and 13 still used laxatives and enemas. Satisfaction rate was 76 percent (16 patients). After one year, defecation frequency was back at the preoperative level in five patients. An ileostomy was created in two more patients because of incontinence and persistent diarrhea. Eleven patients (52 percent) still felt improved. A relation between small-bowel function and functional results could not be demonstrated. CONCLUSIONS: Preoperative evaluation is important but not a guarantee for, successful outcome. Colectomy remains an ultimate option for patients with disabling slow-transit constipation, but patients should be informed that, despite an increased defecation frequency, abdominal symptoms might persist. Any promiscuous use of colectomy to treat constipation should be discouraged.

Carbohydrate intake during prolonged cycling minimizes effect of glycemic index of preexercise meal.

We studied the effects of the glycemic index (GI) of preexercise meals on metabolism and performance when carbohydrate (CHO) was ingested throughout exercise. Six well-trained cyclists performed three counterbalanced trials of 2-h cycling at approximately 70% of maximal oxygen uptake, followed by a performance ride of 300 kJ. Meals consumed 2 h before exercise consisted of 2 g CHO/kg body mass of either high-GI potato (HGI trial) or low-GI pasta (LGI trial), or of a low-energy jelly (Con trial). Immediately before and throughout exercise, subjects ingested a 10 g/100 ml [U-14C]glucose solution for a total of 24 ml/kg body mass. Despite differences in preexercise glucose, insulin, and free fatty acids concentrations among trials, both total CHO oxidation for HGI, LGI, and Con trials, respectively, during steady-state exercise [403 +/- 16, 376 +/- 29, and 373 +/- 24 (SE) g/2 h] and oxidation of the ingested CHO (65 +/- 6, 57 +/- 6, and 63 +/- 5 g/2 h) were similar. There was no difference in time to complete the subsequent performance ride (946 +/- 23, 954 +/- 35, and 970 +/- 26 s for HGI, LGI, and Con trials, respectively). When CHO is ingested during exercise in amounts presently recommended by sports nutrition guidelines, preexercise CHO intake has little effect on metabolism or on subsequent performance during prolonged cycling (approximately 2.5 h).

[Measurement of colon transit time useful in the evaluation of functional constipation]. / Meting van colonpassagetijd nuttig bij de evaluatie van functionele obstipatie.

OBJECTIVE: To determine the colon transit time (CTT) in patients complaining of functional constipation and the correlation between abnormal transit times and the types of constipation and of the symptoms. DESIGN: Retrospective, descriptive. SETTING: Department of Surgery, University Hospital, Nijmegen, the Netherlands. METHOD: The signs and symptoms of 112 patients with infrequent or difficult defaecation, 93 (83%) of them women, with a median age of 42 years (range: 16-72), were recorded by means of a questionnaire. After ingestion of radiopaque markers per day for 10 days, an abdominal survey X-ray was made on day 11. The numbers of markers in the X-ray and per segment (right and left hemicolon and rectosigmoid) were counted; the CTT in hours was calculated by multiplying this number by 2.4. Slowness was defined as more than 45 h for the total CTT and as more than 15 h for the segmental CTT. RESULTS: The total CTT was normal in 33 patients (29%) and prolonged in 79 (71%). The CTT was prolonged only in the rectosigmoid in 14 patients with a normal CTT (42%) and in 50 patients with a prolonged total CTT (63%). Of the patients with a normal total CTT, 13 (39%) had a normal segmental CTT. No statistically significant correlation could be demonstrated between the presence of any symptom and a prolonged CTT. CONCLUSION: Functional constipation may be associated with a normal CTT. Disorders of colonic motility and of rectal evacuation could be distinguished by measuring the total and the segmental colonic transit times.

The evaluation and treatment of functional constipation.

Constipation and defecation may be considered as the last taboo. The inability to defecate or to achieve this only by digital evacuation has never been a popular topic among patients and doctors. Application of tests from the colorectal laboratory has made it possible to study the function of the different parts of the colon and the mechanism of continence. We consider transit studies, defecography, EMG, and anal manometry, all useful as diagnostic procedures for functional constipation. Several causes of functional constipation can be distinguished in slow transit and difficult evacuation or colonic inertia, spastic pelvic floor syndrome, rectocele and intussusception. This article presents our view of the assessment and management of functional constipation.

Amputation for reflex sympathetic dystrophy.

We have reviewed 28 patients with reflex sympathetic dystrophy (RSD) who had 34 amputations in 31 limbs. The amputations had been performed for untenable pain (5), recurrent infection (14) or to improve residual function (15). Only two patients were relieved of pain by amputation, and this could not be predicted. Ten of 14 patients were cured of infection and 9 of 15 patients had improvement of residual function. In 28 of the amputations, RSD recurred in the stump, especially after amputation at a level which was not free from symptoms. Because of recurrence of RSD in the stump or severe hyperpathia only two patients wear a prosthesis. Despite this 24 patients were satisfied with the results.
