Bonebridge (BB) is the first active implantation system for bone conduction that is placed fully under the skin. Experience suggests that BB is characterized by low incidence of postoperative complications. This case report presents a rare case of a 16-year-old girl with incidence of emphysema occurring over the implant 1 year after operation. We performed a computed tomography scan that showed pockets of gas above the floating mass transducer so we provided the revision surgery and sealed the artificial opening with fat from the earlobe and fibrin glue. Since that time, no air has collected in the retroauricular area and the implant has been fully functional.

Artificial Opening

Abstract Background: The surgical creation of an artificial opening of the bowel, called ostomy, can become necessary for very different causative diseases. A special subgroup are ostomies created during emergency surgery, which pose particular challenges to affected patients. This work is dedicated to their detailed characterization.Methods: A retrospective analysis of surgical ostomy creations at an acute care university hospital and an online survey for patients with an ostomy were performed and evaluated.Results: In our study, about one third of all ostomies were created during emergency surgery (37.4%). Compared to patients who received an ostomy during elective surgery, emergency patients had a higher ASA score and diagnoses requiring acute surgical care. Patients undergoing emergency surgery were more likely to have inadequate preoperative medical education (60% vs. 33.3%, p=0.029), and rarely received preoperative ostomy marking (4% vs. 79.2%, p<0.001). Emergency patients underwent minimally invasive surgery less frequently (26.8% vs. 51.3%, p=0.001), and showed a higher rate of peristomal wound dehiscence (9.9% vs. 2.5%, p=0.028). Accordingly, emergency ostomies often resulted in an overall reduction in postoperative quality of life.Conclusion: Ostomies are often created during emergency surgery under suboptimal perioperative conditions. This results in higher complication rates and negative physical and psychological effects. Therefore, intensive interdisciplinary care is essential to provide the best possible care for patients affected by these artificially created intestinal outlets.

AbstractEye opening, a natural and timed event during animal development, influences cortical circuit assembly and maturation; yet, little is known about its precise effect on inhibitory synaptic connections. Here we show that coinciding with eye opening, the strength of unitary inhibitory postsynaptic currents (uIPSCs) from somatostatin-expressing interneurons (SST-INs) to nearby excitatory neurons, but not interneurons, sharply decreases in layer 2/3 of the mouse visual cortex. In contrast, the strength of uIPSCs from fast-spiking interneurons (FS-INs) to excitatory neurons significantly increases during eye opening. More importantly, these developmental changes can be prevented by dark rearing or binocular lid suture, and reproduced by artificial opening of sutured lids. Mechanistically, this differential maturation of synaptic transmission is accompanied by a significant change in the postsynaptic quantal size. Together, our study reveals a differential regulation in GABAergic circuits in the cortex driven by eye opening likely crucial for cortical maturation and function.

Spatio Temporal

On the southern Brazilian coast, the penaeid pink shrimp Farfantepenaeus paulensis (Pérez-Farfante, 1967) is intensively captured by both artisanal and industrial fisheries. In the Ibiraquera Lagoon, artisanal fishing of juvenile stocks has declined sharply over the last 15 years. The traditional management methods used by fishermen are no longer sustainable due to conflicts with the demands of tourism and weak environmental and public agencies. The dynamics of the timing of the artificial opening and natural reformation of a sandbar across the mouth of the lagoon are regarded as a central socio-ecological problem. We evaluated the abundance and biomass variation of F. paulensis throughout the year and along a spatial gradient measured from the sandbar into the lagoon. We also explored the influence of opening the sandbar on the shrimp population. Samples were collected monthly from February 2004 to February 2005, using a 27 mm mesh cast net, in four different areas, with three sites being sampled per area. Small numbers of large shrimps were captured in the upper area, while greater biomass and abundance of small shrimps were observed near the sandbar, suggesting the role of the inner area as a refuge for growing. The highest records for biomass and abundance were recorded during warm months, regardless if the lagoon was open or closed by the sandbar. The Ibiraquera Lagoon could be more productive for fishermen if the sandbar opening was coincident to the period of natural post-larvae influx. Furthermore, coastal stocks could be improved by opening the sandbar again during summer in conjunction with fishing quotas.

AbstractThe timing of the Monte Peron Landslide is revised to 2890 cal. BP based on a radiocarbon-dated sediment stratigraphy of Lago di Vedana. This age fosters the importance of hydroclimatic triggers in the light of accelerating global warming with a predicted increase of precipitation enhancing the regional predisposition to large landslides. Moreover, a layer enriched in allochthonous organic and minerogenic detritus dating to the same wet period is interpreted as response to a younger and yet unidentified mass wasting event in the catchment of Lago di Vedana. Rock debris of the Monte Peron Landslide impounded the Cordevole River valley and created a landslide-dammed lake. Around AD 1150, eutrophication of this lacustrine ecosystem started with intensified human occupation – a process that ended 150 years later, when the river was diverted back into its original bed. Most likely, this occurred due to artificial opening of the river dam. In consequence, Lago di Vedana was isolated from an open and minerogenic to an endorheic and carbonaceous lacustrine system. After a monastery was established nearby in AD 1457, a second eutrophication process was initiated due to intensified land use linked with deforestation. Only in the eighteenth and nineteenth centuries, deposition of organic matter decreased coinciding with climatic (Little Ice Age) and cultural changes. Conversational measures are the likely reasons for a trend towards less eutrophic conditions since AD 1950.

Background: Stoma is an artificial opening of intestinal or urinary tract to the abdominal wall. The purpose of the present study was to identify indications for commonly performed intestinal stomas and to study complications related to it.Methods: This is a retrospective descriptive observational study carried out in a surgical unit of Rajarajeswari Medical College and Hospital, Bangalore from August 2015 to August 2016. Data was collected by previous record files including age, gender, history of presenting illness, indication, type of stoma, type of surgery, appropriate operative findings and follow up of the cases. The results were collected, analysed and compared with other studies.Results: A total of 25 patients were evaluated age ranged between 20-70 years. Out of 25 patients 17 were admitted in emergency while 8 in out-patient department. The most common type of stoma made was loop ileostomy (44%) followed by end ileostomy (28%), end colostomy (16%) and loop colostomy (12%). Main indication for a stoma formation was enteric perforation (56%) followed by carcinoma colon and rectum (32%), perianal sepsis (21%), Koch’s abdomen (11%), penetrating injuries (11%). Of the various complications encountered with intestinal stoma, peristomal skin Excoriation (16%) was the most common complication observed followed by other complications as mentioned in study.Conclusions: In spite of enormous exposure of general surgeons towards stoma formation the complications are inevitable. Early detection of complication and its timely management is the keystone.

Root perforation is an artificial opening occurs in the pulp wall creating communication between the pulp and the exterior. Traumatic (iatrogenic) perforations are due to lack of attention given to details of dental anatomy and failure to consider its variations by the clinician. Perforation of a pulp chamber floor usually occurs due to inattentive access opening or the bur is not properly angulated in relation to the long axis of the tooth
