ABSTRACT

Abstract Phenylketonuria (PKU) is an autosomal recessive defect affecting the metabolic pathway of phenylalanine (Phe), causing hyperphenylalaninemia and neurotoxicity. Diagnosis must occur in the neonatal period and treatment should begin as early as possible. Evidence implies that treatment adherence declines as age advances. The aim was to describe the diet of a subgroup of Chilean adults with PKU currently in follow-up. Fifty-three subjects (49% women) followed up between January 2021 to April 2023 were considered. The concentration of Phe (PheC) in dried blood spots measured by fluorometry and 24-hour dietary recalls were analyzed. The median PheC of the sample was 438µmol/L (interquartile range(IQR):351-585µmol/L). A protein intake of 1.35±0.3 gr/Kg/d was observed of which 87% came from the protein substitute without Phe. Participants had a median Phe intake of 459mg/d (IQR:327-976) and 13.1g/d of fiber intake. Most participants, 51% and 92% reported consuming fruits and vegetables, respectively, and 32% consumed Low-Protein foods. Regarding micronutrients, all participants exceeded 90% adequacy according to recommendations. For vitamin-D and vitamin-B12, 100% is provided by the protein substitute. According to our results, it is mandatory to establish transition programs toward adulthood, to constantly maintain good metabolic control, and to adapt diet therapy to their new lifestyle.

ABSTRACT

Introducción. La hipertrofia de los labios menores se define como tejido labial que sobresale más allá de los labios mayores, puede afectar de manera uni- o bilateral y resultar en dispareunia, interferencia con los deportes, dificultades con la limpieza, irritación e infecciones crónicas del tracto urinario, incomodidad para el uso de prendas ajustadas, además de trastornos psicológicos. Todos estos motivos llevan a las mujeres a la consulta. La reducción de labios menores es el procedimiento estético genital femenino más común. Este trabajo tiene como objetivo presentar técnicas de baja complejidad para resolver diferentes grados de hipertrofia de labios menores. Materiales y métodos. Estudio retrospectivo, observacional que comprendió 3 pacientes entre el periodo de marzo del 2019 a febrero 2020 que Incluyó a pacientes con hipertrofias leves y moderadas. Resultados. En 2 pacientes se realizó escisión directa y en 1, técnica del desepitelizado más lipotransferencia de labios mayores, sin evidenciar complicaciones mayores. Discusión. Si bien en la literatura se han reportado un gran número de técnicas quirúrgicas, cada una de ellas debe adecuarse al tipo de hipertrofia labial. La técnica del desepitelizado permite conservar un borde natural, con conservación de la coloración y textura original de la paciente, aporte neurovascular, pero no es conveniente utilizarla en pacientes de grados mayores de hipertrofia. La escisión directa proporciona una técnica simple para la escisión del exceso de tejido en pacientes con mayor tamaño de sus labios menores, pero elimina el contorno, la coloración y la textura naturales del borde libre, aun así, las pacientes resultan conformes con su nuevo aspecto. Conclusión. La reconstrucción de los labios menores, utilizando las técnicas de desepitelización y escisión directa, es confiable y da un resultado cosmético y funcional exitoso. Estas técnicas son de baja complejidad, tiempo operatorio breve, técnicamente reproducibles, dando gran conformidad y resultando un método seguro


Introduction. Hypertrophy of the labia minora is defined as lip tissue that protrudes beyond the labia majora, can affect unilaterally or bilaterally and result in dyspareunia, interference with sports, difficulties with cleaning, irritation and chronic infections of the urinal tract, discomfort for wearing tight clothes, in addition to psychological disorders. All these reasons lead women to the consultation. Labia minora reduction is the most common female genital cosmetic procedure. This work aims to present low complexity techniques to resolve different degrees of hypertrophy of the labia minora. Materials and methods: retrospective, observational study that comprised 3 patients between the period of March 2019 to February 2020 that included patients with mild and moderate hypertrophy. Results: Direct excision was performed in 2 patients and in 1, de-epithelialization technique plus lipotransference of the labia majora. Without showing major complications. Discussion: Although a large number of surgical techniques have been reported in the literature, each of them must be adapted to the type of lip hypertrophy. The de-epithelialization technique allows a natural border to be preserved, with preservation of the patient's original color and texture, neurovascular supply, but it is not convenient to use it in patients with higher degrees of hypertrophy. Direct excision provides a simple technique for excision of excess tissue in patients with larger labia minora, but removes the natural contour, coloration and texture of the free edge, yet patients are still satisfied with their new appearance. Conclusion. The reconstruction of the labia minora, using de-epithelialization and direct excision techniques is reliable and gives a successful cosmetic and functional result. These are low complexity techniques, short operating time, technically reproducible, giving great conformity and resulting in a safe method

ABSTRACT

Abstract It has been shown that there is a decrease in the concentrations of 25 hydroxyvitamin D (25-OHD) and bone mineral density (BMD) in patients with phenylketonuria (PKU) in their follow-up. Our objective was to determine concentrations of 25-OHD in subjects with PKU and hyperphenylalaninemia (HPA). Transversal analytical study considered three groups: G1-PKU with neonatal diagnosis and formula intake without Phe; G2-HPA, without specific treatment and G3-C control group. Sixteen patients per group (aged 6-23) were included. Levels of 25-OHD, lumbar spine (L2-L4), femur and total BMD, intact parathormone (PTH) and vitamin D (VitD) and calcium intake were calculated. The Kruskal-Wallis statistical test was applied (p-value<0,05). Significant differences were detected in concentrations of 25-OHD between G1-PKU and G2-HPA (38.9 ng/mL; 28 ng/mL, respectively) (NV: >30 ng/mL). G1-PKU had a higher intake of VitD, with differences among groups. There were no significant differences among groups in relation to BMD and intact PTH. In conclusion, G1-PKU under treatment and with good adherence, does not present VitD deficiency and no BMD alterations are observed. In contrast, G2-HPA had a lower intake of VitD and decreased 25-OHD concentrations which could affect the bone architecture in the long term. Further studies on the G2-HPA are suggested.

ABSTRACT

Abstract Since 1992, Chile has had a Newborn Screening Program for Phenylketonuria (PKU), which currently has an incidence of 1:18,916 newborns. The objective of the current study was to describe the 2020 follow up of the Chilean PKU cohort. The variables analyzed were: nutritional status, dietary compliance and neuropsychological functioning. We conducted a descriptive cross-sectional statistical analysis. The 271 subjects with PKU had an average age of diagnosis of 17±8 days and a phenylalanine (Phe) level of 1122±546 umol/L. Approximately 80% of protein requirement came from a protein substitute. For those <18 years of age, 80% had good dietary compliance with Phe level between 120-360 umol/L and those >18 years had a median of 522 umol/L (95%CI 468 - 636). Forty-four percent of the active PKU cohort had overweight/obesity. Eighty-five percent of the cohort >4 years of age had a normal intelligence quotient (IQ) (score 80-120). We observed a negative correlation (p <0.001; 95% CI: - 0.5, -0.2) between IQ score and Phe level. The Chilean protocol and protein substitute subsidy for life, together with the follow-up and continuous education carried out by the clinical team has encouraged compliance.

ABSTRACT

Introducción La quimioterapia neoadyuvante (QTn) es una herramienta de uso cada vez más frecuente en el tratamiento del cáncer de mama. su repercusión es objetivada a partir de parámetros clínicos (examen físico y estudios por imagen) y parámetros anatomo-patológicos sobre la pieza quirúrgica. Existe variabilidad en el impacto de la Qt según el subtipo molecular. Este estudio evalúa el grado de respuesta (clínica y patológica) a la QTn de las pacientes con cáncer de mama subtipo luminal y la tasa de cirugías conservadoras en este subgrupo. Objetivo Describir la tasa de respuesta clínica y patológica obtenida en el subgrupo de pacientes luminales y evaluar la tasa de conversión a cirugía conservadora luego del tratamiento neoadyuvante. Material y método Se analizaron 220 historias clínicas pertenecientes a pacientes que realizaron neoadyuvancia en el periodo 2014-2017 en el Servicio de Patología Mamaria del Hospital Oncológico Marie Curie. Se incluyeron 78 pacientes con diagnóstico de carcinoma invasor subtipo luminal A y B, Her 2 negativas. Se evaluó la tasa de respuesta clínica, patológica y la tasa de cirugía conservadora. Resultados Se clasificaron como Luminal A el 26.9% (n=21) de las 78 pacientes, y Luminal B el 73.1% (n=57). La distribución por tamaño tumoral fue: T1 en el 1.25% (n= 1); T2 en 46.1% (n= 36); T3 en 37.2% (n=29) y T4 en el 15.4% (n=12) de los casos. No presentaban compromiso axilar (N0) el 24.3% de las pacientes (n=19), y se vio afectación ganglionar el 75.5 % (n= 59). El Estadio clínico más frecuente fue el III A (32% = 25 pacientes). El 60.3% (47 pacientes) de los casos tenía indicación de mastectomía de inicio y el 39.7% (41 pacientes) eran candidatas a cirugía conservadora. Posterior a la quimioterapia, se indicaron cirugías conservadoras en el 52.6 % (n=41) y mastectomía en el 47.4% (n=37), con una tasa de conversión a cirugía conservadora del 24.4%. La respuesta clínica completa fue del 28.2% (n=22) y la respuesta patológica completa del 16.6%. Conclusión Se observó una respuesta clínica y patológica acorde a la experiencia de otros centros, sobre todo en el subtipo luminal B, con una alta tasa de conversión a cirugía conservadora del 24.4%. Esto nos permite considerar la quimioterapia neoadyuvante como una opción de tratamiento válida para aquellas pacientes con cáncer de mama subtipo luminal B- Her 2 negativa.


Introduction Neoadjuvant chemotherapy (QTn) is a tool that is increasingly used in the treatment of breast cancer. its repercussion is objectified based on clinical parameters (physical examination and imaging studies) and anatomo-pathological parameters on the surgical specimen. There is variability in the impact of Qt according to the molecular subtype. This study evaluates the degree of response (clinical and pathological) to the QTn of patients with luminal subtype breast cancer and the rate of conservative surgeries in this subgroup. Objective To describe the clinical and pathological response rate in the subgroup of luminous patients and to evaluate the conversion rate in a conservative surgery after neoadjuvant treatment. Material and method We will analyze 220 clinical records belonging to patients that developed during the 2014-2017 period in the Breast Pathology Service of the Marie Curie Oncology Hospital. We included 78 patients with a diagnosis of invasive carcinoma luminal subtype A and B, their 2 negative. The clinical and pathological response rate and the rate of conservative surgery in each group were evaluated. Results Luminal A was classified as 26.9% (n = 21) of the 78 patients, and Luminal B was 73.1% (n = 57). The distribution by tumor size was: T1 at 1.25% (n = 1); T2 at 46.1% (n = 36); T3 in 37.2% (n = 29) and T4 in 15.4% (n = 12) of the cases. There is no axillary involvement (N0) in 24.3% of the patients (n = 19), and the ganglion was affected 75.5% (n = 59). The most frequent clinical stage was III A (32% = 25 patients). Sixty-three percent (47 patients) of the cases had an initial mastectomy indication and 39.7% (41 patients) were candidates for conservative surgery. After chemotherapy, conservative surgeries were indicated in 52.6% (n = 41) and mastectomy in 47.4% (n = 37), with a conversion rate to conservative surgery of 24.4%. The complete clinical response was 28.2% (n = 22) and the complete pathological response was 16.6%. Conclusion A clinical and pathological response was observed according to the experience of other centers, especially in luminal subtype B, with a high conversion rate to conservative surgery of 24.4%. This allows us to consider neoadjuvant chemotherapy as a valid treatment option for those patients with luminal B-Her 2 negative breast cancer.

ABSTRACT

Resumen ANTECEDENTES: las alteraciones cutáneas de la vulva suponen un motivo frecuente de consulta a ginecólogos y dermatólogos. Los síntomas suelen ser imprecisos, con prurito y ardor, por lo que las pacientes tardan en acudir a consultar al médico. OBJETIVO: exponer un caso poco frecuente de pénfigo vulgar vulvar; además, revisar la incidencia, manifestaciones clínicas, diagnóstico y estrategias de tratamiento. CASO CLÍNICO: paciente de 86 años de edad que acudió a consulta por la aparición de lesiones vulvares ulceradas y ardorosas de dos meses de evolución. Se obtuvo una biopsia para el estudio histológico, cuyo resultado fue acantólisis y formación de una vesícula intraepidérmica suprabasal, sin evidencia de disqueratosis o necrosis. Se prescribieron corticoesteroides por vía tópica y oral durante un mes. Después de ese lapso se realizó un estudio de control, esta vez de una lesión más reciente, que evidenció infiltrado inflamatorio linfoplasmocitario con aislados eosinófilos, sin permeación del epitelio. La inmunofluorescencia directa reportó depósitos intercelulares de IgG en todo el espesor de la epidermis y de C3 en los estratos suprabasales, con lo que se confirmó el diagnóstico de pénfigo vulgar. CONCLUSIONES: para establecer el diagnóstico de las dermatosis vulvares poco frecuentes es importante efectuar una correcta correlación clínico-patológica, pues la mayor parte de estas enfermedades se manifiestan casi de forma idéntica.


Abstract BACKGROUND: The skin diseases of the vulva are a frequent reason for consultation with both gynecologists and dermatologists. The clinical symptoms are usually vague as pruritus or stinging and patients usually consult later. OBJECTIVE: To document a case of vulgaris vulvar pemphigus, and review the incidence, clinical presentation, diagnostic strategies and treatment. CLINCAL CASE: An 86-year-old patient who came to medical service for ulcerated and burning vulvar lesions of two months of progression. A biopsy was obtained for the histological study, which resulted in acantholysis and suprabasal intraepidermal vesicle, without evidence of dyskeratosis or necrosis. We prescribe topical and oral corticosteroids during a month. Posteriorly, a control study was performed of the most recent lesion that evidenced lymphoplasmacytic inflammatory infiltrate with eosinophilic isolates, without epithelial permeation. Direct immunofluorescence test reported intercellular deposits, IgG throughout the thickness of the epidermis, and C3 in the suprabasal stratum, thus confirming the diagnosis of pemphigus vulgaris. CONCLUSIONS: For correct diagnosis it is essential the clinic-pathological correlation, because many of these diseases manifest themselves almost identically.

ABSTRACT

Background: Day hospitals can reduce health care costs without increasing the risks of patients with lower respiratory tract infection. Aim: To report the experience of a respiratory day hospital care delivered to adult patients with community-acquired pneumonia (CAP) in a public hospital. Material and Methods: During the fall and winter of 2011 and 2012, adult patients with CAP of intermediate risk categories were assessed in the emergency room, their severity was stratified according to confusion, respiratory rate, blood pressure, 65 years of age or older (CRB-65) score and the Chilean CAP Clinical Guidelines, and were admitted to the respiratory day hospital. Results: One hundred seventeen patients aged 67 ± 16 years, (62% females) with CAP were attended in the respiratory day hospital. Ninety percent had comorbidities, especially chronic obstructive pulmonary disease in 58%, heart disease in 32%, diabetes in 16% and asthma in 13%. Their most important risk factors were age over 65 years in 60%, comorbidities in 88%, failure of antibiotic treatment in 17%, loss of autonomy in 21%, vital sign abnormalities in 60%, mental confusion in 5%, multilobar CAP in 23%, pleural effusion in 15%, hypoxemia in 41% and a serum urea nitrogen over 30 mg/dL in 16%. Patients stayed an average of seven days in the day hospital with oxygen, hydration, chest physiotherapy and third-generation cephalosporins (89%) associated with quinolones (52%) or macrolides (4%). Thirteen patients required noninvasive ventilation, eight patients were hospitalized because of clinical deterioration and three died in hospital. Conclusions: Day hospital care reduced hospital admission rates of patients with lower respiratory tract infections.

ABSTRACT

Objetivo. Comparar la respuesta a la maduración final de las ova y la tasa de ovulación usando dos tratamientos hormonales en hembras de Pimelodus pictus. Materiales y métodos. Hembras maduras recién capturadas fueron superestimuladas con Extracto de Hipófisis de Carpa (EHC) y mezcla del análogo de la hormona liberadora de la gonadotropina de salmón más domperidona, Ovaprim®. Se utilizaron dosis totales de 5.5 y 7.7 mg/kg, y 0.5 y 1 ml/kg respectivamente, dividida en dos dosis, e inyectadas con un intervalo de 12 h (10% de la dosis total en la primera inyección y 90% en la segunda). Resultados. Con tiempo de latencia de 6 h 30±20 min a 7.4±0.2°C. Las hembras en todos los tratamientos respondieron por sobre el 50%, siendo mayor la respuesta en ambos protocolos para EHC (p<0.05). El diámetro ovocitario durante y después de los tratamientos aumentó en todos los casos, siendo mayor y diferente (p<0.05), para los tratamientos con Ovaprim®. La fecundidad se registró entre 818 a 1185 óvulos/hembra. Conclusiones. Se demuestra las posibilidades de reproducción inducida con dos inductores hormonales, siendo EHC superior a Ovaprim.

ABSTRACT

La resistencia antimicrobiana es codificada por algunos elementos genéticos que generan un flujo horizontal, particularmente, en ambientes que están sometidos a una fuerte presión selectiva, como ocurre en el ambiente hospitalario. En tal sentido, los bacilos gramnegativos, en el último tiempo, han cobrado importancia como agentes de infección nosocomial. Objetivo. Investigar la presencia de integrones en aislados clínicos de bacilos gramnegativos y su relación con el fenotipo de resistencia, Material y Métodos. Se analizaron 88 aislados clínicos de distintos servicios del Hospital Torres Galdames, durante el período: junio a diciembre de 2004. Fueron identificadas de acuerdo con su perfil bioquímico y se determinó la susceptibilidad a antimicrobianos mediante el método de difusión en agar. La presencia de integrones se detectó mediante RPC. Se realizó un análisis de cluster para estudiar la relación entre el fenotipo de resistencia y la presencia de integrones. Las cepas fueron genotipificadas mediante ERIC-PCR. Resultados. Dieciocho por ciento de las cepas aisladas correspondió a Proteus mirabilis, 17 por ciento a Escherichia coli y 32 por ciento a bacilos gramnegativos no fermentadores. La mayoría de los aislados presentó una elevada resistencia a los antimicrobianos evaluados: ampicilina 83 por ciento, cefalotina 82 por ciento, ceftriaxona 82 por ciento, ciprofloxacina 81 por ciento, gentamicina 81 por ciento y cotrimoxazol 82 por ciento. De las 88 cepas, 75 por ciento presentó integrones, siendo más común la clase 2. Los resultados del análisis de cluster no revelaron una clara relación entre la presencia de éstos y el perfil de resistencia para los antimicrobianos ensayados. Con la información disponible no fue posible relacionar la presencia de integrones con un determinado patrón de resistencia. Los patrones de bandas obtenidos con la técnica de ERIC-PCR revelaron una gran variedad genética entre las cepas analizadas, definiendo...


The antimicrobial resistance is coded in genetic elements which generate a horizontal flow of information, particularly in conditions that are under strong selective pressure like the nosocomial environment. In that sense, in the last decades, gram negative bacilli have become important agents of nosocomial infection. In order to investigate the presence of integrons among clinical isolates of gram negative bacilli and their relationship with their resistance profile, we studied 88 strains isolated from clinical specimens of different wards of the Hospital Torres Galdames, during the June-December period, 2004. They were identified according to biochemical tests. The antimicrobial susceptibility was evaluated by agar diffusion method. The integron presence was investigated by polymerase chain reaction (PCR). A cluster analysis was carried out to study the relationship between the presence of integrons and the resistance profile. The genotyping of the isolates was carried out by ERIC-PCR technique. Results: Of the isolated strains, 18 percent corresponded to Proteus mirabilis, 17 percent to Escherichia coli, and 32 percent to Non Fermentative Gram Negative bacilli. Most isolates presented high resistance to the antibiotics studied: 83 percent to ampicillin, 85 percent to cephalotin, 82 percent to ceftriaxone, 82 percent to ciprofloxacin, 81 percent to gentamycin and 82 percent to cotrimoxazole. Seventy-five percent of the 88 strains presented integrons. Class 2 integrons were found to be the most common. The results of the cluster analysis did not show a clear relationship among the presence of the integrons and the resistance profile. With the available information it is not possible to relate the integron presence with a certain resistance pattern. The patterns of bands obtained with the technique ERIC-PCR revealed a great genetic variety among the analyzed isolations, defining diverse genotypes, distributed in the different services...

ABSTRACT

Los accidentes escorpiónicos que involucran al género Tityus son la causa más común de los envenenamientos ocurridos en el Estado Mérida. Para estudiar la ocurrencia de estos accidentes de acuerdo a los distritos sanitarios del Estado, se evaluaron el registro de morbilidad mensual EP115 y mortalidad EP113, y la memoria y cuenta de la Coordinación de Epidemiología del Estado Mérida; los años revisados comprenden desde 1994 hasta 2003. En los reportes, se detectó que la mayoría de los accidentes ocurrieron en los distritos sanitarios de Mérida, Tovar y El Vigía. Sin embargo, las muertes registradas (11) ocurrieron en niños con edades iguales o menores a los 9 años y en los distritos sanitarios de Tovar y El Vigía, lo que hace suponer que pudieron ser ocasionadas por la especie Tityus zulianus, que es la más abundante en la zona.

ABSTRACT

In this survey we examined 87 domestic animal stool samples in order to detect the possible presence of microsporidia in animals in close contact with humans in Galicia (NW, Spain). The detection of Enterocytozoon bieneusi spores was confirmed in faecal samples from two dogs and one goat by polymerase chain reaction. None of the positive samples for microsporidia in the staining method were amplified with species-specific primers for Encephalitozoon intestinalis, E. hellem and E. cuniculi. Four rabbits faecal samples reacted with anti-E. cuniculi serum. Our results could indicate the importance of domestic animals as zoonotic reservoirs of microsporidial human infections

ABSTRACT

Two blackfly species Simulium (Cerqueirellum) oyapockense Floch & Abonnenc and S. (Hemicnetha) seriatum Knab are recorded from Argentina, representing the most southern register for both species. S. oyapockense is a species epidemiologically very important, as a vector of onchocerciasis in the Amazonian focus. Both species are described and illustrated and their distribution are reported, in similarity to others like S. roraimense Nunes de Mello and S. ganalesense Vargas et al. in reference to S. oyapockense and S. mexicanum Bellardi similar to S. seriatum are discussed.

ABSTRACT

Estudio a 5 pacientes en edad de 1 a 4 años, que ingirieron sustancias álcalis en 4 casos y ácido en 1 caso, entre los álcalis, la que ocasionó lesiones másgraves fue la soda caústica, los signos y síntomas constatados, posterior a la ingestión del cáustico fueron: lesiones orofaringeas, con dolor y edema a ese nivel; sialorrea y vámitos. La endoscopía Digestiva Alta, realizada en las orimeras horas y días; fue el método auxiliar de diagnóstico más útil para valorar las lesiones esofágicas y el pronóstico de las mismas. Se constataron estenosis esofágicas en 3 casos de ingestión de álcalis fuerte (soda caústica) y en un caso con ácido (ácido muriático : H CL glacial), que requirieron dilataciones esofágicas por esopfagoscopía y se les sigue realizando en forma periódica, con evolución favorable, excepto 1 paciente con estenosis muy severa, con indicación de cirugía de reemplazo. A 3 de estos pacientes se le realizó gastrostomía quirúrgica para su alimentación. En 1 paciente que habia ingerido cáustico alcalino (limpiador de hornos que contiene hidróxido de sodio), se presentaron lesiones esofágicas leves con buena evolución

ABSTRACT

Simulium (Pternaspatha) diamantinum n. sp. is described from females, males, pupae and larvae, collected at Mendoza, San Juan and Neuquen. Some specimens of this species from Laguna del Diamante were included before by Wygodzinsky and Coscarón (1967) in S. strigidorsum Enderlein. The new species is compared with closely related species of the S. (Pternaspatha) "nigristrigatum group". The following synonym is stablished: Simulium (Pternaspatha) bachmanni Wygodzinsky & Coscarón = Simulium (Pternaspatha) nigristrigatum (Enderlein).
