Expanding indication of laparoscopic intracorporeal rectus aponeuroplasty (LIRA) to suprapubic area: LIRA & TAPE / Indicación extendida de la aponeuroplastia intracorpórea de rectos laparoscópica (LIRA) al área suprapúbica: LIRA & TAPE

Laparoscopic intracorporeal rectus aponeuroplasty (LIRA) is a minimally invasive technique described to repair M2–M4 primary and incisional hernias. Defects below this area (M5 – Suprapubic area) could be treated using the concept associated to LIRA, expanding the indication of this technique in combination with a transabdominal partially extraperitoneal (TAPE) repair. The aim of this video is to show the surgical steps in the combination of LIRA & TAPE for M2–M5 ventral hernias (AU)

La aponeuroplastia intracorpórea de rectos laparoscópica (LIRA) es una técnica mínimamente invasiva para la reparación de las hernias incisionales de M2 a M4. Los defectos por debajo de esta zona (M5 – área suprapúbica) se pueden reparar mediante una indicación extendida de LIRA combinada con la reparación transabdominal parcialmente extraperitoneal (TAPE). El objetivo de este video es demostrar los pasos quirúrgicos en la combinación de LIRA & TAPE para hernias ventrales de M2 a M5 (AU)

Desarrollo larvario de algunas especies del género Bregmaceros (Pisces: Bregmacerotidae) del sureste del Golfo de México / Larval development of some Bregmaceros species (Pisces: Bregmacerotidae) from the southeast Gulf of Mexico

We redescribe the larval development of Bregmaceros cantori based on 925 specimens ranging from 1.1 to 20.2 mm in standard length (SL), and describe the larvae of B. atlanticus (27 larvae, 1.7-7.5 mm), B. houdei (six, 1.5-1.9 mm) and B. macclellandi (three, 2.4, 3.4 and 5.4 mm). All specimens were collected in the southern Gulf of Mexico from November 27 through December 6, 1998. Larvae were identified to species, and descriptions were made based on pigmentation, and morphometric and meristic characteristics. We defined five development stages: preflexion, flexion, postflexion, transformation and juvenile. In the preflexion stage B. cantori displayed a greater growth in mouth size and head length relative to SL (positive allometry); there was negative allometry from the flexion to juvenile stage. B. cantori have the shortest body height and head length, thus being the thinnest; whereas B. macclellandi larvae are the most robust ones. From the four species reported from the southern Gulf of Mexico, B. atlanticus larvae are the most pigmented in both head and body, with an homogeneous pattern; B. macclellandi presents a different pigmentation pattern consisting in large melanophore groups with a body arrangement that changes from one stage to the next; additionally, from the preflexion stage it develops both the occipital radius and pelvic fins. B. houdei larvae measuring 1.5 to 1.9 mm have melanophores at the tip of the lower jaw and the head, as well as at the pectoral fin base. Larval development was more pronounced in this B. cantori and B. atlanticus than in specimens from higher latitudes.
