Multiple pieces of lenticules are suggested being used in cases of deep corneal ulcers or perforations
How do tympanic-membrane perforations
affect human middle-ear sound transmission?
due to ingestion of a foreign body can cause complications like mediastinal infection, vascular trauma (aortoesophageal fistula, pseudoaneurysm), paraesophageal abscess, tracheoesophageal fistula, pneumomediastinum, pneumothorax, pericarditis, and some others [10, 11, 14-17].
Another less common cause of perforation
is injury and could result from the insertion of a sharp object into the ear, a blow to the ear, nearby explosion, barotrauma (pressure damage resulting from flying or diving), or a fracture to the base of the skull.
In total, 21 eyes of 21 patients who underwent surgery due to traumatic corneal perforations
3 mm or larger in size were evaluated.
The incidence of perforations
is quoted in the literature as being between 3-10%.
caused by migration of VP shunt is rare but serious complication.
Numerous case reports describe the difficulty in the radiographic diagnosis of small bowel perforations
with studies showing the accuracy of CT-detected small bowel perforation
to range from 33% to 94%.
There are several case reports in the literature regarding perforations
caused by a foreign body such as toothpicks, fishbones, batteries and needles.
Of the 81 perforations
, 64 were associated with known potential risk factors.
Conservative management was planned for all patients and no emergent operative intervention was needed because all perforations
Passive seismic monitoring relies on calibration from perforations
or string shots at known positions to orient downhole 3C receivers (e.
Surgical asepsis, the use of laminar flow, and antibiotic prophylaxis, as well as cutaneous perforations
, have greatly reduced intraoperative bacterial contamination , thus reducing the postoperative infection rate currently around 1% [5, 6].
may require resection and anastomosis in a sense that it takes out diseased segment and also it is better to have a single suture line than multiple.
A study examining worn surgical gloves found that wearing gloves for 90 minutes or less resulted in micro perforations
in 46 of 299 pairs of gloves (15.
