Lymphocutaneous nocardiosis due to Nocardia brasiliensis.

Nocardia species are Gram-positive bacteria responsible for systemic or cutaneous infections in humans. Nocardia brasiliensis is the most common infective agent in the cutaneous form of nocardiosis. We describe a case of a previously healthy man, who presented with lymphocutaneous Nocardia brasiliensis infection, and was successfully treated with trimethoprim-sulfamethoxazole. The identification of the isolate was confirmed by nucleotide sequence analysis of the 16S rRNA gene.

Use of a needleless injection system for digital ring block anesthesia.

Digital ring block anesthesia, which is frequently used before surgery for ingrown toenails, is often extremely uncomfortable for patients and can be the most distressing aspect of the procedure. The authors used a novel needleless injection device to induce digital anesthesia before surgery and compared it in terms of patient discomfort and preference with use of a standard needle and syringe for injection in individuals undergoing simultaneous bilateral nail procedures. Use of the needleless device significantly reduced the pain associated with this procedure and was preferred over use of a standard needle and syringe by all individuals. Other potential advantages of a needleless injection system are discussed.

Acute Complex Type A Dissection associated with peripheral malperfusion syndrome treated with a staged approach guided by lactate levels.

Acute type A aortic dissection can be complicated by visceral malperfusion and is associated with a significant surgical morbidity and mortality. We describe a case of successful management of a complex acute type A dissection with mesenteric and lower limb ischemia treated with endovascular thoracic stenting and femoro-femoral crossover bypass grafting followed by aortic arch repair. To accomplish this, we applied a staged therapeutic approach using serial lactate measurements to assess the adequacy of peripheral perfusion and metabolic status prior to surgical repair of the proximal dissection.

Imported human tungiasis in Greece.

BACKGROUND: Tungiasis is a parasitic skin disease caused by the sand flea Tunga penetrans. It is widespread in poor urban and rural communities in sub-Saharan Africa, the Caribbean and South America. Imported cases of tungiasis are increasingly being reported due to the increased numbers of travelers visiting the affected areas. CASE REPORT: A 28-year-old woman presented with a lesion on the subungual area of the right fourth toe, covered with a central dark crust. The lesion appeared two weeks after returning from Tanzania. The flea Tunga penetrans was identified by histopathological examination of a biopsy material. This is the first case of tungiasis in Greece. CONCLUSIONS: Tungiasis should be considered in the differential diagnosis of parasitic infections in travelers returning from endemic geographical areas.

Balloon control of the saphenofemoral junction during foam sclerotherapy: proposed innovation.

Venous obliteration using foam sclerosant is a relatively new procedure that holds great promise and may prove to be as effective as conventional surgical treatments in obliteration of the great saphenous vein. Foam sclerotherapy can have minor and major complications, most of which occur as a result of gas or sclerosant leakage into the systemic venous system. Conventionally, the saphenofemoral junction is occluded by digital pressure to prevent escape of sclerosant foam into the deep venous system. We propose balloon control of the saphenofemoral junction to prevent sclerosant leakage. This also promotes foam contact with the endothelium in a prolonged, controlled fashion. This method requires no anesthesia, is suitable for ambulatory care, and has been safe and successful in all five cases. Duplex examinations at 1 week and 3 months have shown complete obliteration of the great saphenous vein using this technique.
