RESUMEN

BACKGROUND: Chili peppers have properties that plausibly could either increase or decrease a person's risk of developing colorectal cancer, but their consumption in relation to disease risk has not been well studied. We sought to explore the association between chili peppers intake and the risk of colorectal cancer. METHODS: Eight hundred subjects (400 cases with colorectal cancer and 400 controls) were enrolled in this study. Cases were primarily colorectal cancer patients diagnosed by histopathology at the Department of Intestinal Surgery, Sichuan Cancer Hospital from July 2010 to May 2012. Controls were people receiving routine medical examinations from the Zhonghe Community Health Service Center during the same period of time. An in-person interview was used to collect demographic characteristics, lifestyle, and dietary habits of the subjects in reference to the 10 years prior to disease diagnosis. Conditional logistic regression was conducted to examine the possible association between the risk of colorectal cancer and chili peppers consumption. RESULTS: Compared with persons who consumed chili peppers ≤ 2 times per week, those who consumed chili peppers 3-7 times per week (OR = 1.2, 95% CI 0.75-2.0, P = 0.413) and > 7 times per week (OR = 1.4, 95% CI 0.84-2.2, P = 0.205) were not at an increased risk of colorectal cancer. CONCLUSIONS: The results suggest that the consumption of chili peppers does not increase or decrease the risk of colorectal cancer. This question warrants being re-addressed in a study in which there is prospective ascertainment of dietary characteristics.

RESUMEN

A inibição do quorum sensing (QS) altera a comunicação bacteriana, reduzindo a expressão de fatores de virulência e a formação de biofilmes, o que pode conferir menor pressão seletiva em comparação aos antibióticos tradicionais. As frutas e hortaliças constituem uma fonte rica em compostos com propriedades potenciais de inibição do QS. Entretanto, há pouca referência sobre o potencial de pimentas do gênero Capsicum e de seus compostos isolados como inibidores do QS. Esse trabalho teve como objetivo avaliar o efeito de extratos orgânicos obtidos das variedades de pimenta-malagueta e pimentão vermelho sobre o sistema QS dependente do sinalizador AI-1 (acil homoserina lactona - AHL) em bactérias Gram-negativas. Os extratos foram obtidos por extração em fase sólida e separados em uma fração metanólica e outra amônica; sendo os compostos característicos identificados e quantificados por cromatografia líquida de alta eficiência (CLAE). A atividade antimicrobiana dos extratos foi avaliada pela determinação da concentração inibitória mínima (MIC) e pela curva de crescimento de Chromobacterium violaceum ATCC 12472, Serratia liquefaciens MG1 e Pseudomonas aeruginosa PAO1. O efeito anti-QS dos extratos foi avaliado pelos testes de difusão em ágar e quantificação da produção de violaceína em meio líquido por C. violaceum e sobre a formação de biofilme, avaliado pelo ensaio de cristal violeta e microscopia confocal, em S. liquefaciens e P. aeruginosa nas temperaturas 30 ºC e 37 ºC. Os resultados obtidos pela CLAE indicaram que o extrato metanólico de pimenta-malagueta (EMPM) continha capsaicinoides como a capsaicina e dihidrocapsaicina, luteolina e outros compostos não identificados; já o extrato amônico desta não continha os compostos capsaicinoides. Ambos os extratos de pimentão vermelho continham luteolina e compostos não identificados, mas não apresentaram capsaicinoides. Como o EMPM era representativo dos demais extratos, por conter tanto capsaicinóides quanto luteolina, o foco deste trabalho foi avaliar os efeitos do EMPM sobre fenótipos microbianos nas concentrações 5; 2,5; 1,25 e 0,625 mg/ml, além de utilizar a capsaicina como controle comparativo em concentrações equivalentes às do extrato (25, 50 e 100 µg/ml). Os resultados da atividade antimicrobiana mostraram inibição parcial do crescimento das bactérias nas concentrações sub-MIC (MIC >5 mg/ml) de 5 e 2,5 mg/ml de EMPM. A capsaicina também inibiu parcialmente o crescimento das bactérias a 100 µg/ml, com exceção de S. liquefaciens a 37 ºC, cujo crescimento foi induzido em 50 e 25 µg/ml. A produção de violaceína foi reduzida pelo EMPM a 1,25 e 0,625 mg/ml, sem afetar o crescimento de C. violaceum. Ensaios com C. violaceum CV026, estirpe biosensora capaz de produzir o pigmento na presença de AI-1 exógeno, sugerem que o possível mecanismo de atuação do extrato sobre o sistema QS em C. violaceum 12472 é sobre a síntese do sinalizador, já que não foi observada inibição da produção de violaceína em CV026 pelo extrato. Contrariamente, a capsaicina incrementou a produção do pigmento na estirpe 12472, mas ensaios com a estirpe CV026 indicaram que a capsaicina não atua como sinalizador do QS, uma vez que esta não induziu a produção de violaceína nesta estirpe. Já a formação de biofilme foi incrementada na presença do EMPM, sendo consideravelmente maior em P. aeruginosa a 30 ºC. Igualmente, observou-se indução da formação de biofilme por capsaicina em S. liquefaciens (37 ºC) e P. aeruginosa (30 ºC). Porém, a capsaicina não teve efeito sobre a formação de biofilme de S. liquefaciens quando cultivada a 30 ºC, nem P. aeruginosa a 37 ºC. Os resultados revelam que a produção de violaceína em C. violaceum ATCC 12472 é inibida pelo EMPM, mas não pela capsaicina. Já, o EMPM e a capsaicina, de forma geral, não inibem a formação de biofilme de S. liquefaciens MG1 nem P. aeruginosa PAO1. Outros estudos são necessários para elucidar os mecanismos pelos quais o EMPM e a capsaicina agem sobre os fenótipos avaliados neste trabalho


Quorum sensing inhibition alters bacterial communication by reducing virulence factors expression and biofilm formation, exerting less selective pressure compared to antibiotics. Fruits and vegetables are rich sources of compounds with potential QS-inhibition properties. However, there are few references about the potential of peppers belonging to the genus Capsicum and its isolated compounds as QS inhibitors. This study aimed to assess the effect of organic extracts obtained from Capsicum varieties, pimenta-malagueta (red chili) and pimentão vermelho (red bell pepper), on the AI-1 dependent QS system. The extracts were obtained by solid phase extraction and split into a methanolic and an ammonic fraction. Characteristic compounds were identified and quantified by high performance liquid chromatography (HPLC). The antimicrobial activity of the extracts was assessed by determining the minimal inhibitory concentration (MIC) and the growth curve of Chromobacterium violaceum ATCC 12472, Serratia liquefaciens MG1 and Pseudomonas aeruginosa PAO1. The anti-QS effect of the extracts was evaluated by the agar diffusion assay and the quantification of violacein production was assessed in liquid medium by C. violaceum, as well as in the biofilm formation test determined by the crystal violet assay and confocal microscopy with S. liquefaciens and P. aeruginosa at 30 ºC and 37 ºC. HPLC results showed that the methanolic extract of pimenta-malagueta (EMPM) contained capsaicinoids such as capsaicin and dihidrocapsaicin, luteolin and other unidentified compounds in lower concentrations; while its ammonic extract did not have capsaicinoids. Both pimentão vermelho extracts contained luteolin and other unidentified compounds in low concentrations, but they did not contain capsaicinoids. As EMPM was representative among the extracts because it contained capsaicinoids and luteolin, the focus of this work was to assess the effect of EMPM over microbial phenotypes at concentrations of 5, 2.5, 1.25 and 0.625 mg/ml, using capsaicin as a comparative control at equivalent concentrations to those in EMPM (25, 50 and 100 µg/ml). Antimicrobial activity assays showed a partial inhibition growth of bacteria at sub-MIC concentrations (MIC >5 mg/ml) of EMPM at 5 and 2.5 mg/ml. Similarly, capsaicin partially inhibited bacterial growth at 100 µg/ml, except for S. liquefaciens at 37 ºC in which growth was induced at 50 and 25 µg/ml. Violacein production was reduced by EMPM at 1,25 and 0,625 mg/ml without affecting C. violaceum growth. Assays with C. violaceum CV026, a biosensor strain that produces violacein in the presence of exogenous AI-1, suggest that EMPM reduced violacein production in C. violaceum 12472 by interfering with the AI-1 synthesis. In contrast, capsaicin incremented violacein synthesis in strain 12472, but experiments with strain CV026 revealed that capsaicin does not function as an analog of AI-1. Biofilm formation was increased in EMPM presence, being remarkably superior in P. aeruginosa cultivated at 30 ºC, as opposed to cultivation at 37 ºC. Similarly, capsaicin induced biofilm formation in S. liquefaciens (37 ºC) and P. aeruginosa (30 ºC). However, capsaicin did not affect biofilm formation on S. liquefaciens cultured at 30 ºC, neither on P. aeruginosa at 37 ºC. These results show that violacein production in C. violaceum ATCC 12472 is inhibited by EMPM, but not by capsaicin. In general, EMPM and capsaicin did not inhibit biofilm formation in S. liquefaciens MG1 neither in P. aeruginosa PAO1. More studies are necessary to elucidate the mechanisms by which EMPM and capsaicin affect the studied phenotypes in this work

RESUMEN

OBJECTIVE: Oral Submucous Fibrosis (OSF), is a well-recognized, oral potentially malignant disorder predominantly affecting the South- Asian countries. OSF causes unique generalized fibrosis of the submucosal oral soft tissues, resulting in marked rigidity of the oral mucosa leading to progressive inability to open the mouth, rigidity of lips and difficulty in protruding the tongue. In this review we have discussed the multifactorial etiology of this potentially malignant disorder, including Chillies, Nutritional Deficiencies, Inducible nitric oxide synthsis (iNOS), genetic and immunological predisposition; and most importantly the role of areca nut and the effect of copper content in it.

RESUMEN

Our recent studies conducted in South America have shown that mycotoxin contamination of red chili peppers (RCPs) may be associated with an increased risk of gallbladder cancer (GBC). Whether this relationship exists in India, a country with a high incidence of GBC and high consumption of RCPs, is unclear. We therefore measured concentrations of aflatoxins (AFs) and ochratoxin A (OTA) in RCPs from areas of low, medium, and high incidence of GBC in India, and compared these concentrations with GBC incidence in each area. Twentyone RCP samples were collected from nine cities (eight from a lowincidence area, five from a mediumincidence area, and eight from a highincidence area). Concentrations of AFs and OTA were measured using highperformance liquid chromatography. No significant differences in mean concentrations of AFs and OTA were found in the three areas. AFB1 levels in the lowincidence area (10.81 ?g/kg) and highincidence area (12.00 ?g/kg) were more than 2.2 and 2.4 times higher compared with the maximum permitted level of AFB1 in spices (5.0 ?g/kg) set by the Commission of the European Communities, or that (4.4 ?g/kg) obtained in our previous study in Chile. Our results show that the mean concentrations of mycotoxins in RCPs are similar among the three areas in India with different incidences of GBC. Further studies with human subjects are needed to evaluate any association between AFB1 and GBC.

RESUMEN

Gastric cancer (GC) is the fourth leading cause of cancer death at global level. Diet, alcohol and tobacco, in addition to Helicobacter pylori infection, account for a large number of cases. Some substances contained in foods may influence GC carcinogenesis process; however, the underlying mechanisms have not been fully elucidated. In Mexico and worldwide, a low intake of fruits, non-starchy and allium vegetables, pulses, and foods containing selenium, as well as high intake of salt, salty, salted and smoked foods, chili pepper, processed and grilled/barbecued meats, have been respectively associated with an increased risk of GC. Based on the available evidence, programs for GC prevention and control could be developed and evaluated.

RESUMEN

Chilean red chili peppers contaminated with aflatoxins were reported in a previous study. If the development of gallbladder cancer (GBC) in Chile is associated with a high level of consumption of aflatoxin-contaminated red chili peppers, such peppers from other countries having a high GBC incidence rate may also be contaminated with aflatoxins. We aimed to determine whether this might be the case for red chili peppers from Bolivia and Peru. A total of 7 samples (3 from Bolivia, 4 from Peru) and 3 controls (2 from China, 1 from Japan) were evaluated. Aflatoxins were extracted with acetonitrile:water (9:1, v/v) and eluted through an immuno-affinity column. The concentrations of aflatoxins B1, B2, G1, and G2 were measured using high-performance liquid chromatography (HPLC), and then the detected aflatoxins were identified using HPLC-mass spectrometry. In some but not all of the samples from Bolivia and Peru, aflatoxin B1 or aflatoxins B1 and B2 were detected. In particular, aflatoxin B1 or total aflatoxin concentrations in a Bolivian samples were above the maximum levels for aflatoxins in spices proposed by the European Commission. Red chili peppers from Bolivia and Peru consumed by populations having high GBC incidence rates would appear to be contaminated with aflatoxins. These data suggest the possibility that a high level of consumption of aflatoxin-contaminated red chili peppers is related to the development of GBC, and the association between the two should be confirmed by a case-control study.

RESUMEN

The chiltepin is one of the natural resources of the sinaloense saw, which reaches a commercial value of $100.00 mexican pesos for 250 g approximately, due to the fact that its crop implies penetrating in the low caducifolia jungle and crossing kilometeres to be able to obtain it, in addition the persons of the region who collect it obtain the resource of an irrational way extracting the plant in its entirety from the root, which causes a minor production in the following season of crop. Due to the fact that it is a native plant of the highland region and that the conditions of germination of the seed are achieved when the fruit is consumed by birds and passes for its digestive tract, it is a plant difficult to cultivate. By what preliminary studies were realized to evaluate the germinative percentage of the plant of chiltepín. There was placed to the shade for one month a whole of 2 000 seeds distributed in 4 charolas by 500 seeds each one. To stimulate the germination the hormone of growth was used giberelina. The beginning of the germination was observed to 8 days, reaching a month an average height of 6.5 cm. The percentage of germination that was reached under these conditions is 97 % (in other studies it has been achieved to obtain in the laboratory up to 57 % of germination), which indicates that in the laboratory it is feasible to cultivate it in a favorable way. It is necessary to realize researches related to the growth, development and establishment of the culture of chiltepín to generate in the region economic resources that derive from this activity.


El chiltepín es uno de los recursos naturales de la sierra sinaloense, el cual alcanza un valor comercial de $100.00 pesos mexicanos por 250 g aproximadamente, ya que su cosecha implica internarse en la selva baja caducifolia y recorrer kilómetros para poder obtenerlo, además las personas de la región que lo colectan lo obtienen sin ninguna técnica, pues extraen la planta en su totalidad desde la raíz, lo que ocasiona una menor producción en la siguiente temporada de cosecha. El chiltepín es difícil de cultivar, debido a que es una planta nativa de la región serrana y a que las condiciones de germinación de la semilla se logran cuando el fruto es ingerido por aves y pasa por su tracto digestivo. Por ello se realizaron estudios preliminares para evaluar el porcentaje germinativo de esta planta. Se colocaron a la sombra, por un mes, un total de 2 000 semillas, distribuidas en 4 charolas con 500 semillas cada una. Para estimular la germinación se empleó la hormona de crecimiento giberalina. El inicio de la germinación se observó a los 8 días, alcanzando al mes una talla promedio de 6,5 cm de altura. El porcentaje de germinación que se alcanzó bajo estas condiciones fue de 97% (en otros estudios se ha logrado obtener en el laboratorio hasta un 57% de germinación), lo cual indica que en el laboratorio es factible cultivarlo de manera favorable. Es necesario realizar investigaciones relacionadas con el crecimiento, desarrollo y establecimiento del cultivo de chiltepín para generar en la región recursos económicos que deriven de esta actividad.

RESUMEN

High consumption of red chili pepper has been shown to be a risk factor for gallbladder cancer (GBC) in Chilean women with gallstones, and included mutagens may be important in this context. We aimed to investigate the mutagenicity and mutagens in Chilean red chili pepper in the Ames test using Salmonella typhimurium strains TA98, TA1537, TA100, and TA1535 with and without metabolic activation (S9 mix). Pure capsaicin was tested for mutagenicity using strain TA98. The presence of aflatoxins was evaluated by two-dimensional thin layer chromatography, and then the concentrations of aflatoxins B1, B2, G1, and G2 were measured by an HPLC system. In strain TA98, the mean numbers of revertant colonies with and without the S9 mix were 2.5- and 2.2-fold higher than those of each negative control, respectively. However, pure capsaicin did not show mutagenic activity in strain TA98. Aflatoxin contamination of red chili pepper was confirmed, and the concentrations of aflatoxins B1 and G1 were 4.4 ng/g and 0.5 ng/g, respectively. Our findings suggest that low-level but protracted exposure to aflatoxins may be associated with the development of GBC in Chilean women who carry gallstones.

RESUMEN

To evaluate cytological atypical changes in apparently healthy oral mucosa exposed to smoking, alcohol, hot meals, and peppers using the AgNOR and Papanicolaou methods. A total of 180 individuals were evaluated, of which 60 were smokers, 34 were alcohol users, 52 were habitual peppers and hot meal (exposed) consumers, 24 were non-exposed, and 10 were patients with Oral Squamous Cell Carcinoma (OSCC), as an internal control. Cytological materials were obtained by brushing of buccal mucosa, on the border of the tongue and on the floor of the mouth, and participants underwent the Papanicolaou test for cytological changes and AgNOR staining for evaluation of the mean number of AgNOR dots per nucleus. SPSS program was used to perform the Pearson chi-square test. The 95% confidence level, Odds Ratio (OR), and the 95% Confidence Intervals (CI) were used. The features of cytological atypia were verified among 10 individuals, including 5 smokers, 2 alcohol users, 2 hot meals and peppers consumers, and one non-exposed. For atypia among tobacco smokers, the adjusted Odds Ratio (OR) and the 95% CI were found to be 2 (0.246-16.24). Increased keratinization was detected among 27 (45%) of the smokers (P < 0.0001), 17 (32.7%) of the pepper and hot meals consumers (P < 0.005), 4 (11.8%) of the alcohol consumers, and among 2 (3.7%) of the non-exposed group. Statistical analyses revealed a greater mean number of AgNORs per nucleus in smokers (3.68) followed by (2.82) alcohol consumers, compared to the habitual peppers and hot meal consumers (2.28) and the non-exposed group (2.00). What's more, 80% of the smears with cytological atypia were identified with 6 +/- 2 AgNOR mean count. The increase of the variables suggests that the evaluation of epithelial atypical changes in individuals exposed to smoking and alcohol carcinogens may be a useful screening tool. While hot meals and peppers did not seem to be a risk for oral mucosal proliferation, they increased the potency of keratinization and infection.

RESUMEN

Avaliou-se a atividade antimicrobiana do extrato bruto (EB) e frações hexânica (FH), clorofórmica (FC) e acetato de etila (FA) das pimentas malagueta (C. frutescens), cambuci (C.bactum var. pendulum), cumari (C.baccatum var praetermissum) e pimentão magali (C. annuum var. annuum). O EB foi obtido por extração líquido-líquido em solução hidro-alcoólica (etanol 96ºGL) seguida de fracionamento pelo sistema de solventes com grau de polaridade crescente, resultando em FH, FC e FA.(...) O pimentão obteve apenas atividade bacteriostática frente a seis bactérias. Estes resultados demonstram que a pimenta cumari, cambuci e malagueta podem ser utilizadas como agentes conservantes naturais em alimentos.

RESUMEN

Our previous study indicated an association of chili pepper consumption with gallbladder cancer (GBC) in the presence of gallstones (GS) in Chile. We investigated whether or not a similar association was present in Hungary, where mortality from GBC is high and chili peppers are frequently consumed. In a case-control study, we compared 41 female GBC patients with GS and 30 gender and GS-matched hospital controls. Trained staff interviewed all subjects to determine socioeconomic status, family history, past history and life style habits (smoking, alcohol intake, dietary habits and elimination habits). Because mean ages differed significantly between the case and control groups, age-adjusted odds ratios (ORs) were calculated. A shorter education period (< 10 years / > or = 16 years) was indicated to be a risk factor (age-adjusted OR (95%CI): 3.2 (1.2-8.7)). In addition, the intake of Hungarian hot pepper (yes / no) was found to be significantly higher in the GBC cases than in controls (age-adjusted OR (95%CI): 8.4 (2.3-30.4)). There were no differences between the case and control groups for other variables. Multivariate logistic regression analysis retained only Hungarian hot pepper consumption as a significant independent risk factor for GBC. Its age-adjusted OR was 16.2 (95%CI: 2.1-126.2), while there were no differences associated with low education, frequent consumption of fresh fruit and vegetables, low socioeconomic status or smoking. Hungarian hot pepper consumption was identified as a risk factor for GBC by multivariate logistic regression analysis.

RESUMEN

BACKGROUND: Red-hot chili pepper and other spices have been blamed for causing or exacerbating symptoms of anal pathologies like anal fissure and hemorrhoids. AIM: To determine if consumption of chilies increases symptoms of acute anal fissures. METHODS: Individual patients were randomized to receive capsules containing chili or placebo for one week in addition to analgesics and fiber supplement. Patients were asked to note score for symptoms like pain, anal burning, and pruritus during the study period. After 1 week, cross over treatment was administered to the same group of patients with the same methodology and results were noted at the end of 2 weeks. RESULTS: Fifty subjects were recruited for this study. Forty three of them completed the trial (22 in the chili group and 21 in the placebo group). The daily mean pain score was significantly lower in the placebo group in the study period. Score 2.05 in chili group and 0.97 in placebo group. There was a significant burning sensation experienced by the patients in the chili group (score 1.85 for the chili group vs 0.71 for the placebo group). Patient’s mean recorded improvement score was significantly higher after taking placebo. Eighty one point three percent patients preferred placebo while 13.9 percent preferred chilies. Two patients had no preference. CONCLUSION: Consumption of chili does increase the symptoms of acute anal fissure and reduces patient compliance.


RACIONAL: A pimenta vermelha e outras especiarias têm sido responsabilizadas por agravar a sintomatologia das doenças anais, tais como fissuras e hemorróidas. OBJETIVO: Determinar se o consumo de pimentas vermelhas aumentaria os sintomas em fissuras anais agudas. MÉTODOS: Pacientes foram recrutados e randomizados para receber cápsulas contendo pimenta ou placebos por 1 semana, somadas a analgésicos e suplementos de fibras. Foi solicitado que anotassem um escore de sintomas, tais como dor, queimação anal, prurido durante o período de estudo. Após 1 semana o tratamento foi cruzado e administrado ao mesmo grupo de pacientes com a mesma metodologia e os resultados foram anotados ao final de duas semanas. RESULTADOS: Cinqüenta pacientes foram selecionados e 43 completaram o estudo (22 no grupo pimenta e 23 no grupo placebo). O escore médio diário de dor foi significativamente mais baixo (2,05 no grupo pimenta e 0,97 no grupo placebo). A sensação de queimação foi sentida de modo significativo no grupo pimenta (1,85 para o grupo pimenta vs 0,71 para o grupo placebo). O escore de melhora dos sintomas foi significantemente alto após tomar o placebo. Oitenta e um virgula três porcento dos pacientes preferiram tomar placebo contra 13,9 por cento que preferiram pimenta. Dois pacientes não referiram preferências. CONCLUSÃO: O consumo de pimentas agrava os sintomas de fissuras anais agudas.

RESUMEN

AIMS: This study was aimed to determine whether there was any relationship between consumption of chillies and postoperative symptoms after closed anal sphincterotomy in patients with chronic anal fissure. MATERIALS AND METHODS: Patients were randomly assigned to receive analgesics and fiber supplement alone (control patients) or consumption of 1.5 g chilli powder twice daily along with identical fiber and analgesics (chilli group). The evaluation of symptoms (pain, anal burning, and pruritus) during the postoperative period was assessed by means of patients' self-questionnaires. The amount of analgesic tablets consumed and the frequency of stool during the study period were also noted. RESULTS: 28 patients were recruited in each arm. Postoperative symptoms were higher in the group consuming chillies during the first postoperative week. The global scores for postoperative pain (7.60 in chilli group and 2.95 in control group, p < 0.001) and for anal burning (8.85 for the chilli group vs. 4.21 for the control group, p < 0.0001) were significant. CONCLUSION: This study shows that consumption of red chillies after anal fissure surgery should be forbidden to avoid postoperative symptoms.

RESUMEN

The aim of this study was to determine whether there was any relation between consumption of chilies and postoperative symptoms after hemorrhoidectomy in patients with grade III or IV hemorrhoidal disease. A total of 60 patients were randomly assigned to receive antibiotics and analgesics alone (control patients) or daily consumption of 3 g of chili powder along with identical antibiotics and analgesics (chili group). The evaluation of symptoms-pain, anal burning, pruritus, bleeding-during the postoperative period was assessed by means of patients' self-questionnaires. A global score for evaluating each postoperative symptom was compared between the two groups at the 1-week follow-up. No significant difference in age, sex distribution, or grade of disease was noted between the two groups at baseline. The incidence of post-hemorrhoidectomy symptoms was higher in the group consuming chilies during the first postoperative week. The global score for postoperative pain (14.60 for the chili group vs. 7.97 for the control group, p < 0.001) and for anal burning (12.90 for the chili group vs. 7.82 for the control group, p < 0.0001) were significant. Although bleeding (6.95 in the control group and 7.57 in the chili group, p < 0.81) and pruritus (8.06 in the control group and 8.75 in the chili group, p < 0.69) were more common in the chili group, the difference did not achieve statistical significance. This study shows that consumption of 3 g of red chilies per day during the postoperative period after hemorrhoidectomy increases the intensity of typical postoperative symptoms, stool frequency, and the consumption of analgesics.

RESUMEN

We explored the risk factors for gallbladder cancer and explanations for its sharp and constant incidence increase in Chile since the 1970s. We compared 114 consecutive patients with verified gallbladder cancer, diagnosed 1992-1995, to 114 matched hospital patients with gallstones, using conditional logistic regression analysis. Low education showed a nonsignificant positive relationship with gallbladder cancer [odds ratio (OR) = 2.3, 95% confidence interval (CI) 0.8-6.2], and low socioeconomic level showed a significant relationship (OR = 5.0, 95% CI 1.5-17.3). A very long history of gallstone disease was significantly more prevalent among cases (OR = 11.0, 95% CI 1.4-85.2). Significant red chili pepper consumption was observed in gallbladder cancer patients (OR = 2.9, 95% CI 1.6-5.2). Low intake of both fresh fruit and sugar as soft drinks was associated with gallbladder cancer, with ORs of 6.4 (95% CI 1.4-30.3) and 3.6 (95% CI 1.3-10.1), respectively. Multivariate analysis kept only a very low socioeconomic status and red chili pepper consumption as significant independent risk factors for gallbladder cancer, ORs of 6.3 (95% CI 1.7-23.0) and 3.2 (95% CI 1.7-5.9). Longstanding gallstone cases were removed from the multivariate model because all were in the low and very low socioeconomic groups, reinforcing the association. Patients with gallbladder cancer differed from matched controls by exhibiting lower socioeconomic levels, having a much longer history of gallstone disease and presenting a dietary pattern characterized by high red chili pepper consumption and low fresh fruit intake.

RESUMEN

A prospective case-control study was conducted in Trivandrum, India, to evaluate the dietary risk factors for stomach cancer. One hundred and ninety-four patients with stomach cancer registered at the Regional Cancer Centre (RCC), Trivandrum, Kerala, India, during the period 1988-1991 were considered as cases. A minimum of one control (n = 305), matched for age (+/- 5 years), sex, religion and residential area was selected from the visitors to RCC during the same period. Interviews were carried out using a predetermined structured food frequency questionnaire. The information collected also included socio-demographic/economic background, tobacco chewing, tobacco smoking and alcohol habits. Data were analysed using a multiple logistic regression model. Odds ratios for all dietary variables were estimated. Increased risks were observed with higher consumption of rice (OR 3.9; 95% CI 1.6-10.0). Risk was high for those consuming spicy food (OR 2.3; 95% CI 1.1-5.0), high consumption of chilli (OR 7.4; 95% CI 4.0-13.5) and consumption of high-temperature food (OR 7.0; 95% CI 3.7-12.9). On multivariate analysis, high consumption of rice, high consumption of chilli and consumption of high-temperature food were found to be independent risk factors.
