RESUMO
Resumen Introducción: La laringectomía total (LT) tiene como secuela la perdida de la voz, pero otra consecuencia no estudiada es la pérdida del olfato. Objetivo: Demostrar que la "maniobra de inducción del flujo aéreo nasal" (MIFAN) rehabilita el olfato en pacientes con LT. Material y Método: Estudio cuasiexperimental antes-después en pacientes laringectomizados por cáncer de laringe del Servicio de Otorrinolaringología del Hospital Barros Luco Trudeau (HBLT) de Santiago de Chile. Evaluación a través de encuesta, examen físico, nasofibroscopía y test olfatométrico. Pacientes con alteración del olfato por transmisión serán enrolados y se enseñará la MIFAN. Resultados: Se estudiaron 12 pacientes: 10 hombres, 2 mujeres. Edad promedio 66,3 años, todos autovalentes. 66,6% presentó anosmia y 33,3% hiposmia. Todos lograron realizar la maniobra. Posrehabilitación el 100% presentó presencia de olfato valorada por olfatometría. Población intervenida similar a otras series en cuanto a sexo y edad. La erigmofonación facilita la rehabilitación con MIFAN. La rehabilitación del olfato se logró en todos y paralelamente mejoró el sentido del gusto. Conclusión: La MIFAN es una técnica sencilla, barata y asequible para lograr rehabilitar el sentido del olfato en pacientes laringectomizados.
Abstract Introduction: Total laryngectomy (TL) has as a consequence the loss of voice, but another not studied consequence is the loss of smell. Aim: To demonstrate that the "nasal airflow inducing maneuver" (NAIM) rehabilitates smell in patients with TL. Material and Method: A quasi-experimental before-after study in laryngectomized patients for laryngeal cancer from the Otorhinolaryngology Service (ENT) of the Barros Luco Trudeau Hospital (BLTH) at Santiago, Chile. Evaluation through survey, physical examination, nasofibroscopy and olfactory test. Patients with transmission impairment of smell were enrolled and NAIM was performed. Results: 12 patients were studied: 10 men, 2 women. Average age 66.3 years. All self-supporting. 66.6% presented anosmia and 33.3% hyposmia. They all managed to perform the maneuver. Post-rehabilitation, 100% presented the presence of smell assessed by olfactometry. Intervened population similar to other series in terms of sex and age. Esophageal speech facilitates NAIM rehabilitation. Rehabilitation of smell was achieved in all of them and in parallel, the sense of taste improved. Conclusion: NAIM is a simple, cheap and affordable technique to rehabilitate the sense of smell in laryngectomized patients.

Resumen El objetivo de este trabajo es discutir la presentación y el manejo de la aplasia congénita unilateral del cartílago alar. En este informe, presentamos el caso de un paciente sometido a rinoseptoplastia abierta primaria que presenta aplasia congénita del cartílago alar izquierdo que se repara con cartílago septal. Se discute el manejo de casos y se revisa la literatura. Las anomalías nasales congénitas son poco frecuentes. La ausencia aislada de cualquier estructura nasal específica es aún más rara. El diagnóstico preoperatorio en una nariz hispana es difícil, pero cuando se encuentra este defecto congénito, puede repararse con cartílago septal u otros tipos de cartílago, dependiendo de la disponibilidad del injerto, con buenos resultados. Se recomienda un enfoque abierto para este tipo de patología. La aplasia unilateral del cartílago alar podría reconstruirse con éxito utilizando el cartílago septal a través de un abordaje abierto.
Abstract The objective of this work is discussing the presentation and management of unilateral congenital aplasia of the alar cartilage. In this report, we present the case of a patient undergoing primary open rhinoseptoplasty presenting congenital aplasia of the left alar cartilage that is repaired with septal cartilage. Case management is discussed, and the literature is reviewed. Congenital nasal abnormalities are rare. The isolated absence of any specific nasal structure is even more rare. Preoperative diagnosis in a Hispanic nose is difficult, but when this deformed congenital is found, it can be repaired with septal cartilage or other types of cartilage, depending on the availability of the graft, with good results. An open approach is recommended for this type of pathology. Unilateral alar cartilage aplasia could be successfully reconstructed using septal cartilage through and open approach.

RESUMEN El adenoma pleomorfo constituye la neoplasia benigna más frecuente de las glándulas salivales mayores, y puede también presentarse en otros sitios con mucha menor frecuencia como orofaringe, hipofaringe y nasofaringe. El adenoma pleomorfo intranasal es muy infrecuente y los casos descritos en la literatura local se refieren a tumores septales. Se presenta un caso clínico de una paciente que consulta por obstrucción nasal unilateral a derecha asociado a, epistaxis y epífora ipsilateral con estudio imagenológico y biopsia que sugiere adenoma pleomorfo de la pared lateral nasal. Se realiza revisión bibliográfica al respecto.
ABSTRACT The pleomorphic adenoma is the most frequent benign neoplasm of the major salivary glands. It can also present itself in other places with much less frequency such as oropharynx, hypopharynx and nasopharynx. The intranasal pleomorphic adenoma is very unusual and the cases described in the local literature address septal tumors. A clinical case is presented of a patient who consulted for unilateral right nasal obstruction associated with epistaxis and ipsilateral epiphora with imaging study and biopsy suggesting pleomorphic adenoma of the lateral nasal wall. A bibliographic review is made in this regard.

Varicocele is a prevalent pathology among infertile men. The mechanisms linking this condition to infertility, however, are poorly understood. Our previous work showed a relationship between sperm functional quality and the ability of spermatozoa to respond to capacitating conditions with increased membrane fluidity and protein tyrosine phosphorylation. Given the reported association between varicocele, oxidative stress, and sperm dysfunction, we hypothesized that spermatozoa from infertile patients with varicocele might have a combined defect at the level of membrane fluidity and protein tyrosine phosphorylation. Semen samples from infertile patients with and without grade II/III left varicocele were evaluated for motion parameters (computer-assisted semen analysis [CASA]), hyperactivation (CASA), incidence and intensity of protein tyrosine phosphorylation (phosphotyrosine immunofluorescence and western blotting), and membrane fluidity (Laurdan fluorometry), before and after a capacitating incubation (6 hr at 37 degrees C in Ham's F10/BSA, 5% CO(2)). Spermatozoa from varicocele samples presented a decreased response to the capacitating challenge, showing significantly lower motility, hyperactivation, incidence and intensity of tyrosine phosphorylation, and membrane fluidity. The findings reported in this article indicate that the sperm dysfunction associated to infertile varicocele coexists with decreased sperm plasma membrane fluidity and tyrosine phosphorylation. These deficiencies represent potential new pathophysiological mechanisms underlying varicocele-related infertility.

OBJECTIVE: To establish the predictive value of serum inhibin B levels as an indicator of the presence of testicular spermatozoa in nonobstructive azoospermia, compared with the traditional serum FSH marker. DESIGN: Prospective study. SETTING: Private high-complexity reproductive center with university affiliation. PATIENT(S): Seventy-eight patients with nonobstructive azoospermia, 15 patients with obstructive azoospermia, and 10 fertile volunteers. INTERVENTION(S): Blood samples, testicular sperm extraction, percutaneous epididymal sperm aspiration, and semen collection. MAIN OUTCOME MEASURE(S): Serum levels of inhibin B and FSH and presence of spermatozoa on TESE, PESA, or regular semen analysis. RESULT(S): Patients with nonobstructive azoospermia has significantly higher levels of serum FSH and significantly lower levels of inhibin B. Mean inhibin B serum levels were significantly higher in patients with nonobstructive azoospermia who had spermatozoa on TESE than in those in whom no spermatozoa were found (89.31 +/- 73.24 pg/mL vs. 19.23 +/- 22.34 pg/mL), but mean FSH serum levels did not have similar predictive power (21.37 +/- 12.92 IU/mL vs. 19.27 +/- 10.28 IU/mL). The cut-off level of inhibin B separating both groups, as determined by the receiver-operating characteristic curves, was >53 pg/mL. CONCLUSION(S): Serum inhibin B level seems to be more accurate than serum FSH level in prediction of the presence of testicular spermatozoa in patients with nonobstructive azoospermia.

OBJECTIVE: To report the birth of healthy twin males after the use of testicular spermatozoa from a nonmosaic patient with Klinefelter's syndrome. DESIGN: Case report. SETTING: Private reproduction center with university affiliation. PATIENT(S): A couple undergoing intracytoplasmic sperm injection (ICSI) combined with testicular sperm extraction because of the husband's secretory azoospermia and a nonmosaic 47,XXY peripheral blood karyotype. The wife, a healthy female, presented with a history of oligomenorrhea. INTERVENTION(S): ICSI was performed using testicular spermatozoa; 3 mM pentoxifylline solution was used to induce sperm motility because the spermatozoa recovered were all immotile. MAIN OUTCOME MEASURE(S): Normal fertilization, embryo cleavage, pregnancy outcome, and peripheral blood karyotype of the newborns. RESULT(S): Thirteen metaphase II oocytes were injected. Seven of them fertilized normally and six did not fertilize. Three good-quality embryos (4-cell stage class II) were transferred, and four were cryopreserved at the two-cell and four-cell stages using a slow freezing protocol. Twelve days after ET, a beta-hCG determination was positive. Ultrasonographic examination revealed three intrauterine fetal sacs, but one of them showed a fetal pole without cardiac activity and vanished in subsequent ultrasonographic examinations. The patient delivered twins with normal male peripheral blood karyotypes. CONCLUSION(S): Normal outcome after the use of testicular sperm extraction and ICSI in a nonmosaic patient with Klinefelter's syndrome reaffirms the notion of low transmission risk of this gonosomal aneuploidy.

Se revisan 17 historias clínicas de pacientes con diagnóstico de egreso pulmonar. Se describe y analiza una malformación congénita pulmonar y vascular poco frecuente, pero de interés tanto clínico como quirúrgico que, desde los trabajos de Pryce ha sido llamado secuestro pulmonar. La malformación consiste en una porción de tejido pulmonar separada del árbol bronquial, en situación intralobar o extralobar, con alvéolos hipoplásicos y bronquios dilatados que dan la apariencia de quiste, neumonía o exhudado pulmonar. Este fragmento congénitamente aislado tiene un sistema vascular propio que emerge por lo general de la aorta. Se analizan los procedimientos diagnósticos utilizados. El tratamiento consistió en un primer momento en dominar la infección y, controlada ésta, practicar los exámenes hasta llegar a un diagnóstico preciso y realizar la resección.
