[Benign subcutaneous emphysema after nail penetration. Case report and important differential diagnoses].

Kantelberg C1, Meyer C, Harland U.Author information 1Zentrum für Orthopädie und Unfallchirurgie, Klinikum Saarbrücken, Winterberg 1, 66119, Saarbrücken, Deutschland, ckantelberg@klinikum-saarbruecken.de.AbstractCrepitus under the skin after penetrating injuries: harmless benign subcutaneous emphysema or life-threatening infection with gas-producing bacteria (gas gangrene because of Clostridium perfringens, crepitating cellulitis because of anaerobic Streptococcus or other coliforme bacteria)? We report a case of a 74-year-old male who developed massive crepitation of the left upper extremity and the lateral thoracic wall and mediastinal emphysema after sustaining a laceration of the left thumb and forefinger from a nail. Because there was the suspicion of gas gangrene we performed generous skin incisions of the ventral and dorsal part of the hand, the forearm and upper arm and open wound treatment. A triple antibiotic therapy was initiated. Due to fast regression of the subcutaneous emphysema and the mediastinal emphysema, continuing lack of symptoms, negative smear test results from the beginning and low infection parameters in the blood all wounds could be closed 9 days after primary surgery. The suspicion of gas gangrene was not confirmed so the diagnosis of benign subcutaneous emphysema was made.

Atraumatic painless compartment syndrome.

Blanchard S1, Griffin GD, Simon EL.Author information 1Emergency Department, Akron General Medical Center, Akron, OH, USA.AbstractAcute compartment syndrome is a time-sensitive diagnosis and surgical emergency because it poses a threat to life and the limbs. It is defined by Matsen et al (Surg Gynecol Obstet. 1978;147(6):943–949) as "a condition in which increased pressure within a limited space compromises the circulation and function of the tissues within that space." The most common cause of compartment syndrome is traumatic injury. A variety of other conditions such as vascular injuries, bleeding disorders, thrombosis, fasciitis, gas gangrene, rhabdomyolysis, prolonged limb compression, cellulitis, and nephrotic syndrome may also cause compartment syndrome. Patients who are elderly, have preexisting nerve damage, or have psychopathology may have an atypical presentation. This case highlights the first report of a 75-year-old woman who developed painless bilateral compartment syndrome in the absence of traumatic injury.
