Cross-Cultural Adaptation and Validation of the Pain Scale for Plantar Fasciitis to Spanish

The aim of this study was the validation and transcultural adaptation of the Pain Scale for Plantar Fasciitis to Spanish, following the steps defined by “Guidelines for the process of cross-cultural adaptation of self-report measures.” A cross-sectional study was driven in 153 patients with unilateral plantar fasciitis diagnosis. Statistical analysis measured the internal consistency, the test-retest reliability, the construct validity with the Spanish version of Foot and Function Index, and a factorial analysis. The questionnaire Pain Scale for Plantar Fasciitis was also given to a group of 10 people who received a physiotherapy treatment based on manual therapy, therapeutic exercise, and health education, which aim was to determine the questionnaire's sensitivity to changes. The questionnaire showed high internal consistency and test-retest reliability (Cronbach's α = 0.99, intraclass correlation coefficient = 0.98 [0.97-0.98]), good convergent validity with a moderate correlation with the Foot and Function Index (rho = 0.677, p < .0001) and no floor or ceiling effects were detected. The factorial analysis revealed that the first 3 factors showed 42.47% of variance, finding only 1 latent feature. Statistically significant differences were found in those patients who received physiotherapy treatment after 1 month, revealing that the questionnaire was sensitive to changes in the symptoms of subjects with plantar fasciitis. The Spanish version of Pain Scale for Plantar Fasciitis has proved to be a valid, reliable, and change-sensitive tool for patients with plantar fasciitis.     

Synergy of the Tropical Earthworm Pontoscolex corethrurus and Oil Palm Bagasse in the Removal of Heavy Crude Oil

The tropical endogeic earthworm Pontoscolex corethrurus, a non-standard species used in ecotoxicity, has been found in crude oil-contaminated habitats. We estimated the removal of total hydrocarbons from heavy crude “Maya” oil on an artificially contaminated soil with a median lethal concentration of P. corethrurus and an addition of oil palm bagasse. P. corethrurus had a high survival rate, and the addition of oil palm bagasse led to a greater growth and an increase in abundance of bacteria and fungi. The activity of P. corethrurus and the nutritional quality of oil palm bagasse had a significant impact on the removal of a larger amount of petroleum hydrocarbons from contaminated soil. We concluded that the endogeic earthworm P. corethrurus and oil palm bagasse acted synergistically to achieve a more effective removal of total petroleum hydrocarbons from soil. These results show the potential for using P. corethrurus to remove, either directly or indirectly, crude oil from soil.

     

On the need of a sampling strategy in biological monitoring: The example of hexane exposure

Ambient and biological monitoring of hexane exposure were repeatedly carried out in 14 female shoe makers. Airborne hexane (Ci-H) was measured in 4-h samples collected by a diffusive method. Urinary spot samples were collected before, during (at noon), and at the end of a work shift. 2,5-Hexanedione (2,5HD) in urine collected at noon was poorly related to morning Ci-H. End-of-shift 2,5HD were also poorly related to afternoon air samples. The correlation was still relatively low when end-of-shift 2,5HD was related to 8-h TWA Ci-H (r= 0.44; P<0.01 on=" a=" linear=" scale,=" and=">r-0.58, P< 0.01=" on=" a=" log-log=" scale).=" end-of-shift=" 2,5hd=" levels=" estimated=" on=" the=" basis=" of=" pre-shift=" values=" using=" a=" mathematical=" model=" were=" much=" higher=" (2.3=" times=" on=" average)=" than=" those=" experimentally=" measured=" during=" the=" study=" period.=" owing=" to=" its=" relatively=" long=" half-time,=" 2,5hd=" seems=" to=" be=" influenced=" not=" only=" by=" current=" exposure,=" but=" also=" by=" hexane=" absorbed=" during=" the=" day(s)=" preceding=" sampling.=" the=" lack=" of=" a=" sampling=" strategy=" may=" account=" not=" only=" for=" inconsistencies=" between=" environmental=" and=" biological=" data,=" but=" also=" for=" a=" possible=" misuse=" of=" biological=" monitoring=" when=" utilized=" for=" risk=" assessment.=" despite=" sometimes=" poor=" correlations=" with=" ci-h,=" 2,5hd=" may=" still=" be=" preferred=" to=" other=" indicators=" as=" a=" marker=" of=" effective=" internal=" dose.=" a=" sampling=" strategy=" should=" ensure=" that=" measured=" values=" are=" representative=" of=" the=" individual=" risk=" for=" adverse=">     

Involvement of cholecystokinin receptors in the control of striatal dopamine autoreceptors

Summary The interaction of locally perfused cholecystokinin-8 (sulphated) with systemically administered apomorphine was studied on the release of dopamine and its metabolites using microdialysis in the neostriatum of the halothane-anaesthetized male rat. Dialysate levels of dopamine, 3,4-dihydroxyphenylacetic acid and homovanillic acid were assayed by high performance liquid chromatography in combination with electrochemical detection. Perfusion with cholecystokinin-8 (100 M but not 1 M or 10 nM) increased the dialysate levels of dopamine without affecting those of DOPAC or HVA. At low concentrations (1 M and 10 nM but not 1 nM), cholecystokinin-8 counteracted the inhibitory effect of apomorphine (0.05 mg/kg, s. c.) on dopamine release. This counteraction was antagonized by perfusion with the cholecystokinin-8 antagonist proglumide (3 M). At this concentration, proglumide perfused alone was without effect on basal or apomorphine-reduced levels of dopamine. The results indicate a facilitatory effect of cholecystokinin-8 on dopamine release in rat neostriatum only at high concentrations. At lower concentrations, cholecystokinin-8 appears to modulate dopamine release by an inhibitory effect on dopamine autoreceptors possibly involving an intramembrane interaction between presynaptic cholecystokinin-8 receptors and dopamine autoreceptors.

Anthropometric and nutritional assessment in Italian elderly subjects

The aims of this anthropometric study on 486 non-institutionalized subjects aged 60 and over were to assess the body mass index (BMI), to evaluate possible sex and age-linked differences of BMI and to find whether there were any correlations with systolic and diastolic blood pressure. To this end, the subjects were divided into three age groups: A: 60-69 years, B: 70-79 years and C: > or =80 years old. The results showed a high prevalence (74%) of overweight or clearly obese subjects (BMI >25.1 for men and BMI > 23.9 for women) (70% male and 77% female). Both the BMI and diastolic blood pressure showed a decreasing trend in the three age groups and were significantly correlated in the total population (p < 0.001). A dietary investigation using a 24-hour recall method, repeated on three separate days, was carried out on a subsample of 90 subjects, selected at random from the total population. They underwent in-depth anthropometric assessment (BMI, four skinfolds, mid-arm, waist and hip circumferences, midarm muscle and fat areas, body fat percent). The trend of the anthropometric assessment reflected that of the total population. Total energy intake in both sexes did not significantly differ from the Italian RDA (Recommended Dietary Allowance). As regards the three macronutrients, no significant differences in protein and carbohydrate intakes were found between the sexes. However, in the females, fat intake was over the Italian DRA (30%) and below it in the males. Calcium intake was lower than the Italian RDA (1,000 mg/day) in most males (77%) and females (89%). However, iron and vitamin intakes were adequate in most subjects. As regards age-linked differences, there were non significant changes in the percentage of energy intake from proteins of the males whereas this decreased with age and was significantly different (p < 0.05) in the females. No significant differences were found in the percentage of energy intake from carbohydrates and fats.     

Microscopic endoluminal tumorectomy

PURPOSE: We herein report our experience with transanal endoscopic microsurgery. The new technique combines an endoscopic view and access of the rectum under gas insufflationviaa stereoscopic telescope with all conventional surgical maneuvers such as tissue preparation, coagulation and control of bleeding, irrigation, suction, and, finally, suturing of the parietal defect. METHODS: The main indication for transanal endoscopic microsurgery is the removal of broad-based sessile polyps and excision of early rectal cancers. We performed local excision of pT2, G1-2 adenocarcinomas and excision of advanced rectal cancer in high-risk patients. The reported series includes 35 consecutive patients, who have been enrolled in a prospective clinical trial. Five patients were excluded for different reasons. The patients were submitted to 29 total wall excisions with or without perirectal fat and one mucosectomy. RESULTS: Postoperative histologic examination showed 9 adenomas and 21 adenocarcinomas. Morbidity included 2 (5.6 percent) perioperative and 2 (5.6 percent) late complications. There was no operative mortality and the mean postoperative hospital course was six days. All patients are in follow-up observation with a mean time of 10.3 months. In the group of adenomas and adenocarcinomas, we did not observe local recurrence. CONCLUSIONS: Considering our experience with the overall results reported by other authors, we believe that transanal endoscopic microsurgery is the procedure of choice for the treatment of rectal polyps and early rectal cancers provided strict patient selection criteria are met.
