RESUMEN

Helminth species of Neotropical bats are poorly known. In Mexico, few studies have been conducted on helminths of bats, especially in regions such as the Yucatan Peninsula where Chiroptera is the mammalian order with the greatest number of species. In this study, we characterized morphologically and molecularly the helminth species of bats and explored their infection levels and parasite­host interactions in the Yucatan Peninsula, Mexico. One hundred and sixty-three bats (representing 21 species) were captured between 2017 and 2022 in 15 sites throughout the Yucatan Peninsula. Conventional morphological techniques and molecular tools were used with the 28S gene to identify the collected helminths. Host­parasite network analyses were carried out to explore interactions by focusing on the level of host species. Helminths were found in 44 (26.9%) bats of 12 species. Twenty helminth taxa were recorded (7 trematodes, 3 cestodes and 10 nematodes), including 4 new host records for the Americas. Prevalence and mean intensity of infection values ranged from 7.1 to 100% and from 1 to 56, respectively. Molecular analyses confirmed the identity of some helminths at species and genus levels; however, some sequences did not correspond to any of the species available on GenBank. The parasite­host network suggests that most of the helminths recorded in bats were host-specific. The highest helminth richness was found in insectivorous bats. This study increases our knowledge of helminths parasitizing Neotropical bats, adding new records and nucleotide sequences.

RESUMEN

Parasitic intestinal infections occur worldwide and affect the poorest and deprived populations. In Mexico, indigenous peoples live with the highest levels of poverty and marginalization. This study aimed to analyze the occurrence of intestinal parasites among Mayan children from the villages of Xkalakdzonot and Paraíso in Yucatán State. Stool samples from 83 children were examined using two coproparasitological tests (formalin-ethyl acetate concentration and FLOTAC Pellet techniques). The overall prevalence of intestinal parasites in children was 65.1%. Six protozoa and four helminths were identified. Blastocystis sp. (44.6%), Giardia intestinalis (26.5%), and Entamoeba coli (26.5%) were the most prevalent parasites. The prevalence of helminth infections (7.1%) was lower in children from Xkalakdzonot than in Paraíso (29.3%). The study provides relevant information on the occurrence of intestinal parasites in Mayan children from two villages. This data, therefore, can be used by local health authorities to plan appropriate programs for parasite control, considering suitable drug therapies and health education.

RESUMEN

Resumen: La atención odontoestomatológica a pacientes especiales, requiere en muchos casos un abordaje clínico rápido y efectivo con el propósito de mejorar su calidad de vida. El síndrome de Rubinstein-Taybi, es un trastorno poco común, donde se observan anomalías en los genes CREBBP y EP300, descrito en 1963 por dos médicos estadounidenses, entre las manifestaciones y características principales tenemos: retraso mental (moderado o severo), microcefalia, primer dedo de la mano o del pie engrosado, retraso del crecimiento, facies característica con maxilar hipoplásico, fisura palpebral inclinada de forma descendente, paladar ojival, dientes de implantación irregular apiñados, estrabismo, orejas mal formadas de implantación baja, nariz en forma de pico, cejas espesas, párpados largos. El concepto de adaptación del paciente a la consulta odontológica representa lograr y mantener su colaboración durante el tratamiento mediante un proceso de enseñanza-aprendizaje. Se realizó el modelamiento de conducta, exposición gradual, refuerzo positivo, restricción física activa con apoyo de la madre. Resultados: Se logró restablecer la salud bucal del paciente en forma satisfactoria.


Abstract: Medical and dental care for special needs patients oftentimes require effective and rapid clinical approach so as to improve patients' quality of life. Rubinstein-Taybi syndrome is a rare disorder where anomalies in genes CREBBP and EP300 are observed. This syndrome was first described in 1963 by two North American physicians. Among the main characteristics and manifestations of this syndrome we can count mental retardation (moderate or severe) microcephaly, thickened first finger or toe, growth retardation, characteristic face with hypoplastic lower jaw, downward-sloping arched palate, palpebral fissure, irregularly implanted teeth, crowded teeth, strabismus, low-set, malformed ears, beak-shaped nose, bushy eyebrows and long eyelids. The concept of patient adaptation to the dental office entails achieving and preserving his collaboration during treatment by means of a show-and-tell process. Behavior was modeled with gradual exposition, positive reinforcement and active physical restraint with the mother's help. Results: The patient's oral health was satisfactorily reestablished.

RESUMEN

BACKGROUND: Surgically induced adhesions complicate up to 100% of abdominal surgeries. Food and Drug Administration-approved treatments are generally not only less effective than desired but they also have major contraindications. Oxychlorine species, including chlorine dioxide (ClO2), suppress scar formation in infected wounds without affecting keratinocytes while reducing fibroblast proliferation. The aim of the present study was to evaluate the effect of oxychlorine solutions containing ClO2 on adhesion formation. METHODS: Male Wistar rats were subjected to Buckenmaier model of surgical adhesions and treated with either oxychlorine solutions containing ClO2 (40-150 ppm) or isotonic saline solution. To increase the severity of adhesions, peritonitis was produced by intraperitoneal administration of a diluted nonlethal dose of feces (50 mg/kg). Wound strength of the healed wound was measured to evaluate the effects of oxychlorine solutions. In addition, an oxychlorine solution of lesser efficacy (at 100 ppm) was compared with three available anti-adhesion materials. RESULTS: Reproducibility of the model was validated in 26 rats. Oxychlorine solutions containing ClO2 (40-110 ppm) significantly reduced postsurgical adhesion formation without affecting the strength of the healed wound. Higher concentrations (120 and 150 ppm) had no effect. Fecal peritonitis significantly increased, and solutions with ClO2 at 110 ppm significantly reduced adhesion formation. The effect of the oxychlorine solution was significantly greater than that of Interceed, Guardix, Seprafilm, and isotonic saline solution. CONCLUSIONS: ClO2-containing oxychlorine solutions could be an innovative strategy for the suppression of surgical adhesion formation, with the additional advantage of contributing antiseptic properties.

RESUMEN

A fraqueza do músculo quadríceps é um fator ofensivo na osteoartrite (AO), contribuindo para o desenvolvimento e agravamento do dano articular. Os objetivos deste estudo foram avaliar diferenças no recrutamento dos músculos que compõem o quadríceps (vasto medial obliquo - VMO, reto femoral - RF e vasto lateral - VL) durante a atividade concêntrica (subida) e excêntrica (descida), em mulheres portadoras de OA nos joelhos, comparado com um grupo saudável. Foram estudadas 60 mulheres, idade acima de 40 anos, divididas em dois grupos: um grupo com OA (GOA), com 32 voluntárias e o grupo de comparação (GC), composto de 28 pessoas. Não foram observadas diferenças estatisticamente significantes no recrutamento muscular nos dois grupos, com exceção da subida e descida do segundo degrau. Apesar de não encontrar diferenças no recrutamento dos dois grupos, estudos futuros utilizando uma metodologia que permita comparar recrutamento e força muscular, são necessários para comprovar esta relação.


The quadriceps weakness is a risk factor for osteoarthritis (OA), which contributes to the development and joint impairment aggravation. The aim of this study was to evaluate the differences of recruitment of the quadriceps muscles (vastus medialis oblique – VMO, rectus femoris – RF, vastus lateralis – VL) during the concentric activation (ascending) and eccentric (descending), in women with OA on the knees, comparing with a healthy group. Sixty women over forty years were evaluated and divided into two groups: a group of osteoarthritis (GOA), with 32 subjects and the control group (GC), with 28 people. It was not observed statistical differences on muscle recruitment of both groups, except on ascending and descending the second step stairs. Although it was not observed differences on the recruitment of both groups, future studies using a methodology that enable to compare the relationship between recruitment and muscle strength are needed.

RESUMEN

The aims were (a) to quantify the number of Duddingtonia flagrans chlamydospores per gram of faeces (CPG) recovered from sheep administered with different oral doses and, (b) to describe the relationship between CPG and eggs per gram of faeces (EPG) on the efficacy to reduce Haemonchus contortus infective larvae. Three doses of chlamydospores per kg BW were orally administered during seven days: (T1) non treated control group, (T2) 1 x 10(6), (T3) 2.5 x 10(6) and (T4) 5 x 10(6). Three lambs, infected with H. contortus, were used per group. Faeces were obtained from the rectum of each lamb during the fungal administration period (days 0-6) and for six days after that period. Four coproculture replicates were made from each animal in days 2, 4, 6, 8 and 10. A higher chlamydospore dose produced higher CPG in faeces (p < 0.05), but a clear dose dependent effect was not found either in the larvae reduction or in the CPG:EPG ratio. When ratios were re-analyzed, independently of the treatment groups of origin, a better efficacy was obtained with a ratio from 5 to 10 CPG:EPG and a higher ratio (> 10 per egg) showed a lower reduction efficacy (p < 0.05). The binomial analysis showed that for each unit of increment in CPG:EPG ratio there was a reduction of larvae number until a point (between 5 and 10 CPG:EPG) where no further reduction was detected. The surface response test indicated that the number of larvae was reduced by CPG until possible saturation. The highest CPG:EPG ratios did not necessarily improve efficacy of D. flagrans.

RESUMEN

Cysts of the inguinal cord are disorders that simulate inguinal hernias and manifest as inguinal masses and, in some cases, are accompanied by pain that can simulate a complicated inguinal hernia. We report the third case of a round ligament cyst in a 21-year-old female with a mass in the right inguinal area with intermittent pain. The patient was subjected to surgical exploration of the right inguinal area where a round ligament cyst was found. The ligament was resected and reported as a serous cyst. The patient's outcome was excellent and she was discharged 24 h after surgery. She has been followed up for 3 months without recurrence. Round ligament cysts are very rare disorders, and the diagnosis is perioperative. Resection of the round ligament causes complete symptom relief, and every case requires inguinal hernioraphy.

RESUMEN

The ability of estradiol to affect phenylephrine-induced contraction and the subsequent increase in resting tone, associated with capacitative Ca(2+) entry across the plasma membrane, was evaluated in rat aortic rings incubated in Ca(2+)-free solution. The incubation with estradiol (1-100 nM, 5 min) inhibited both the phenylephrine-induced contraction and the IRT. Neither cycloheximide (1 microM; inhibitor of protein synthesis) nor tamoxifen (1 microM; blocker of estrogenic receptors) modified the effects of estradiol. Estradiol (100 microM) also blocked the contractile response to serotonin (10 microM) but not to caffeine (10 mM). In addition, estradiol (100 microM) inhibited the contractile responses to cyclopiazonic acid (1 microM; selective Ca(2+)-ATPase inhibitor) associated with capacitative Ca(2+) influx through non-L-type Ca(2+) channels. Finally, estradiol inhibited the Ca(2+)-induced increases in intracellular free Ca(2+) (after pretreatment with phenylephrine) in cultured rat aorta smooth muscle cells incubated in Ca(2+)-free solution. In conclusion, estradiol interfered in a concentration-dependent manner with Ca(2+)-dependent contractile effects mediated by the stimuli of alpha(1)-adrenergic and serotonergic receptors and inhibited the capacitative Ca(2+) influx through both L-type and non-L-type Ca(2+) channels. Such effects are in essence nongenomic and not mediated by the intracellular estrogenic receptor.

RESUMEN

Caveolins are a family of integral membrane proteins implicated in various cell functions, including the organization and inactivation of signaling molecules of G protein-coupled receptors. We tested the ability of human caveolin scaffolding peptide-1 (CSP-1) to regulate norepinephrine- (NE) or histamine (HIS)-induced increases on intracellular calcium concentrations ([Ca(2+)]i). In cultured rat vascular smooth muscle cells (VSMC), CSP-1 inhibited in a concentration-dependent manner NE- and HIS-induced increases in [Ca(2+)]i. This effect can be explained by the fact that CSP-1 inhibited a common signaling pathway. We tested the ability of this peptide to decrease the activation of PLC-beta3 and MAPK. CSP-1 inhibited the expression of the activated form of both enzymes, suggesting a direct effect of the peptide on the signaling cascade. CSP-1 readily enters VSMC in culture, as observed when FITC-conjugated CPS-1 is added to cell culture media. Taken together, these data suggest that CSP-1 blocks the effects of NE and HIS on [Ca(2+)]i of VSMC by inhibiting the activation of PLC-beta3 and MAPK.

RESUMEN

Helicobacter pylori infection is relevant, due to its role in different gastric pathologies; there are several diagnostic methods, which are divided into invasive and non-invasive. In the first category histology has been considered the gold standard, while other methods include imprint with Gram stain and rapid urease test, which can produce dependable results. The aim of this study is to compare several available techniques for H. pylori diagnosis to know their sensitivity and specificity. We studied 88 patients, 50 women and 38 men, with age range from 17 to 83 years (48.8+/-14.3) from the Endoscopy Department of the 20 de Noviembre Medical Center; in all five to eight biopsies were taken from gastric mucosa to perform rapid urease test, Gram-stained imprint and histology. Endoscopic findings included gastritis (87.50%), pangastritis (2.30%) and another diagnoses (10.22%). Rapid urease test was positive in 40 patients and negative in 48, while imprint was 34 and 54, respectively. Sensitivity and specificity were as follows: rapid urease test, 84.8 and 78.5%, and imprint 75.8 and 83.6%, respectively. In conclusion, H. pylori diagnosis by rapid urease test is a dependable and quick method. On the other hand, imprint is useful but depends on the ability of the personnel who perform the test.

RESUMEN

OBJECTIVE: To determine a simplified method for nutritional status evaluation in surgical patients to identify patients prone to develop complications. METHODS: A prospective study was carried out to determine prognostic index of patients in whom major abdominal surgery was performed, based on nutritional assessment. We proposed a simplified and accessible method for daily evaluation of patients in any hospital even in an emergency setting. The following parameters were used: complete blood count (CBC); blood chemistry (BC); protrombine time (PT); total serum protein (TSP), and anthropometrics. RESULTS: Study population consisted of 200 patients divided in two groups depending on type of surgical intervention, i.e., emergency or elective procedure. Complications associated with different stages of malnourishment were analyzed by simplified nutritional assessment system. Of 200 patients analyzed, 123 had several stages of malnutrition, 62 were malnourished, complicated patients (50.41%), and 77 had adequate nutritional status; of these, 10 also had complications (12.99%). DISCUSSION: We were able to conclude that simplified nutritional assessment system is not a useful absolute predictive indicator of possible complications. However, some parameters could be useful to identify patients with nutritional depletion with tendency for post-surgical complications.

RESUMEN

OBJECTIVE: To determine advantages and disadvantages of manual vs mechanical sutures in colon surgery. MATERIAL AND METHODS: A retrospective study of clinical files of 84 colon surgery patients was conducted, to establish morbidity and mortality of these patients with special emphasis in length of surgical procedure and type of suture used during procedure (either manual or mechanical). RESULTS: Of 84 patients included in this study, manual suture was used in 70 (group 1) and mechanical suture in 14 (group 2). Most common preoperative diagnosis was diverticular disease in 22 cases (26.2%), 20 for group with manual suture, and two for group with mechanical suture. Most common surgical procedure was colectomy with ileoproctoanastomosis in group 1 and lower anterior resection with coloproctoanastomosis in group 2. Five cases presented complications (2.85%) with manual suture, while only one case presented complications in group 2 (7.14%). Main complications were dehiscence in group 1 and stenosis in group 2. DISCUSSION: There were no significant differences between both types of suture in terms of time of surgical procedure; there were no statistical differences for both techniques in terms of morbidity and mortality. However, there is shorter time of recovery in patients in whom mechanical suture was used with less tissue edema due to manipulation and less disability period.

RESUMEN

Introducción. Chlamydia trachomatis se considera el agente causal de tracoma, salpingitis, endometritis y podría estar involucrada en la ruptura prematura de membrana (PMR) y amenaza de parto prematuro (PDT). El objetivo de este trabajo fue determinar la presencia de antígenos de C. trachomatis y anticuerpos contra C. trachomatis en mujeres embarazadas con PMR, PDT (ambos grupos de etiología desconocida) y mujeres con embarazo normal (NP).Material y métodos. Se obtuvieron 50 muestras endocervicales por cada grupo de mujeres embarazadas, para la determinación de antígenos de C. trachomatis, por el método de inmunofluorescencia directa. Asimismo fueron tomados 5 ml de sangre venosa, para identificar la presencia de anticuerpos contra C. trachomatis por inmunofluorescencia indirecta. Resultados. Seis por ciento (3/50) de las pacientes con PMR presentaron antígenos de C. trachomatis y anticuerpos IgG anti-C. trachomatis. Dos por ciento (1/50) con PDT tuvieron antígenos de C. trachomatis y anticuerpos IgM anti-C. trachomatis. Seis por ciento (3/50) de las pacientes con NP mostraron antígenos de C. trachomatis, pero no anticuerpos anti-C. trachomatis. Sin embargo, en 10 por ciento (5/50), 10 por ciento (5/50) y 16 por ciento (8/50) con PMR, PDT o NP, respectivamente; solamente se encontraron anticuerpos IgG anti-C. trachomatis. Conclusión. El hallazgo tanto de antígenos como anticuerpos anti-C. trachomatis en los tres grupos estudiados, resalta la importancia de la oportuna identificación de la infección, para la aplicación del tratamiento adecuado, para prevenir las secuelas de la infección, tanto en las mujeres embarazadas como en sus productos.

RESUMEN

Objetivo. La terapia para la neurocisticercosis parenquimatosa con praziquantel (PZQ) de 15 días ha mostrado ser efectiva. Las concentraciones en plasma y líquido cefalorraquídeo (LCR) del PZQ son más elevadas después de dos horas de su administración. Nosostros pensamos que el mantenimiento de concentraciones elevadas de PZQ por seis horas pudieran ser una terapia cisticida adecuada para estos pacientes. Métodos. Tratamos 30 pacientes con neurocisticercosis parenquimatosa con tres dosis orales de 25 mg por kg de peso de PZQ con intervalos de dos horas. Ellos recibieron dexametasona 10 mg intramuscular por tres días consecutivos a la administración del PZQ. Resultados. En 21 pacientes desaparecieron los quistes, en siete hubo una desaparición de 30 a 60 por ciento y dos pacientes permanecieron sin cambios. Del número total de quistes, hubo una tasa de desaparición de 70.7 por ciento. Dos pacientes presentaron crisis convulsivas, seis cefalea y otros más náusea. Ningún paciente cursó con convulsiones durante el tratamiento con antiepilépticos. Conclusión. El costo y el tiempo de administración del PZQ se reducen significativamente y la inflamación que sigue a la destrucción del parásito es tratada secuencialmente
