Introduction The purpose of this paper is to evaluate the Silver Bullet Wound Closure Device (SBWCD, Boehringer Laboratories, Norristown, PA), a new device for delayed primary closure of fasciotomy wounds. Materials and Methods A retrospective review was performed over a period of 36 months of all patients with an upper extremity fasciotomy that could not be closed primarily. Cases that underwent fasciotomy closure with the SBWCD were separated from the patients that had a split thickness skin graft (STSG). Results Seven patients had their wound closed with the SBWCD within 10 days (mean of 7.4 days). The seven patients that underwent STSG had their wound closed in an average of 8.4 days. The average number of days between the day of the fasciotomy incision and the date of the placement of the SBWCD was 1.9 days. STSGs were placed on the fasciotomy wounds on an average of 10.3 days after the date of the fasciotomy incision. We found that the SBWCD allowed for starting to approximate the edges of the fasciotomy wound at an earlier time when compare to STSG (2.1 vs 10.3 days).Conclusions We feel that the SBWCD as a one-stage procedure provides a consistent and efficacious way to manage upper extremity fasciotomy wounds while minimizing the morbidity associated with STSG. Elimination of a secondstage procedure reduces hospital costs. Our findings may help to inform surgeons about an available alternative when an upper extremity fasciotomy wound is not amenable to primary closure.

Lipomas may be located in all parts of the body and may be confused clinically with other soft tissue masses. They infrequently occur in the head and neck. A large neck mass (greater than 10 cm) with a rapid growth rate should raise concerns about a possible malignancy. Failure to distinguish a liposarcoma from a lipoma may represent a medicolegal pitfall. Surgical excision of a lipoma is often used as the definitive treatment modality, and alternative treatments described for lipomas range from liposuction to steroid injections. In the present study, a 60-year-old man who presented with a rapidly enlarging submental mass is described. A 15 cm x 12 cm mass was successfully removed. The surgery produced excellent cosmetic results and no functional impairment. An integrated review of the literature regarding etiology, epidemiology, diagnostic and treatment modalities of submental lipomas follows.

Pseudoaneurysms of abdominal aorta after inferior vena cava (IVC) filter placement are uncommon, with associated morbidity and mortality. We report a case in which an abdominal aortic pseudoaneurysm resulted from erosion of a Bird's Nest (Cook, Bloomington, IN) IVC filter into the wall of the abdominal aorta. A 64-year-old woman with an IVC filter placed 10 years prior presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen and pelvis showed a 1.4-cm x 2.0-cm infrarenal aortic pseudoaneurysm adjacent to the IVC filter site. A Zenith endograft (Cook) was used via an open femoral artery exposure to successfully treat the pseudoaneurysm.

En este artículo se presentan los hallazgos del sitio Cueva Abra del Toro, un abrigo rocoso localizado al sur del Valle de Yocavil. La información que proviene del sitio es importante para ampliar el conocimiento sobre la ocupación prehistórica durante el Holoceno por fuera de la región de Puna. Existen dos datos que sostienen esta afirmación. En primer lugar, la Cueva Abra del Toro presenta la ocupación más antigua, en estratigrafía para el valle, y en segundo lugar, en la estratigrafía del sitio hay evidencia de ceniza volcánica que proviene la erupción de mayor intensidad conocida para el Holoceno en los Andes. Este depósito de ceniza separa las ocupaciones de la cueva, una pre-cerámica (anterior a la erupción) y una pre-cerámica y otra cerámica (posteriores a la erupción). La información que incorpora este nuevo sitio contribuye a complementar y complejizar la construcción del conocimiento científico sobre las ocupaciones prehistóricas en los valles mesotermales del Noroeste Argentino.

No patient in our study population developed a delayed PTX or HTX after 3 hours. Our results suggest that shortening the observation period after asymptomatic penetrating thoracic injuries to 3 hours is safe, cost-effective, minimizes radiation exposure, and may help relieve congested urban EDs.

A detailed analysis of two faunal assemblages from Las Pailas -SsalCac18 (1) archaeological locality, in the northern section of the Calchaquí Valley (Salta province, Argentina), dated to the Regional Developments Period (ca. AD 1000-1430), is presented. Las Pailas was a large urban settlement, inhabited throughout most of the aforementioned Period. The assemblages come from two trash-dumps of different sizes. The smaller one (Structure 2) was found in a space formed between the walls of two rooms. The other dump (Test pit 3) is much bigger, it belongs to a 140 centimeters thick archaeological deposit situated in the town's outer limits. As both assemblages reflect different lengths of time of accumulation, the analysis was aimed at approaching the relationship between a global strategy for the management of faunal resources at Las Pailas (Test pit 3), and its adaptation to particular constraints in a shorter time (Structure 2). The data presented here contributes to enlarge our knowledge of the geographical and historical variability of the zooarchaeological record of the center and northern Calchaquí Valley.

A detailed morphometric description of a dog skull from the pre-Hispanic archaeological site La Isla de Tilcara (northwestern Argentina, ca AD 800-1200) is presented. The resulting data were compared with those of dog skulls from other South American archaeological sites to establish dog morphotype. The examined skull belonged to a small, long-snouted dog, similar to the smallest morphotypes from the central Andes.
