Infección extraintestinal debida a bacterias del género Campylobacter / Extraintestinal infections due to Campylobacter SPP

Campylobacter jejuni causa principalmente enteritis disenteriforme; los casos debidos a C. fetus son raros, mayormente bacteriemiaen inmunosuprimidos. Presentamos dos casos de enfermedad diarreica con bacteriemia, ambos con hemorragia digestiva,debida a C. jejuni, un caso inusual de infección de anerurisma de la arteria femoral y un caso de bacteriemia recurrente conprobable foco en marcapasos en un anciano sin otro factor de inmunosupresión, los dos últimos debidos a C. fetus. Todos lospacientes tuvieron evolución favorable. Recomendamos prestar atención a los hemocultivos que resulten positivos para efectuarlos subcultivos adecuados para recuperar, identificar y determinar la sensibilidad a los antimicrobianos de este tipo de bacterias microaerofílicas.

Campylobacter jejuni often causes enteritis; cases due to C. fetus are rare: it causes mostly bacteremia in patients with immunosuppression.We present two cases of diarrheal disease with bacteremia, both with gastrointestinal bleeding due to C. jejuni, an unusual case ofC. fetus infection of an aneurysm in the femoral artery, and one case of recurrent C. fetus bacteremia with probably focus in apacemaker in an elderly patient without another cause of immunosuppression. All patients had a favorable evolution. We recommendspecial attention to the positive blood cultures in order to recover and identify this type of microaerophilic bacteria, and determineantimicrobial susceptibility.

Percutaneous Ultrasound-Guided Thrombin Injection in Iatrogenic Arterial Pseudoaneurysms: Effectiveness and Complications

PURPOSE: To evaluate and describe the efficacy and side effects of a percutaneous thrombin injection under ultrasonography guidance for the treatment of iatrogenic pseudoaneurysms. MATERIALS AND METHODS: Eighteen consecutive iatrogenic pseudoaneurysm cases were treated with a thrombin injection. The thrombin was injected into the pseudoaneurysm cavity using a 22-gauge needle under ultrasonographic guidance. The causes of the pseudoaneurysms are as follows: post coronary angiography (9 cases), percutaneous coronary balloon angioplasty (5 cases), cerebral angiography (1 case), transhepatic chemoembolization (1 case), percutaneous transfemoral arterial stent insertion (1 case) and bone marrow aspiration for a marrow transplant (1 case). RESULTS: Only one case required a secondary thrombin injection due to recurrent flow in the pseudoaneurysm lumen, which was detected at the follow up Doppler ultrasound. Other seventeen cases were successfully treated on the first trial. There were no technical failures or complication related to the procedure. The average amount of thrombin injected was 733 IU. Nine out of 18 treated patients (50%) showed mild reactions to the thrombin including mild fever (4 cases), chilling sensation (3 cases), a chilling sensation with mild dyspnea (1 case), mild chest discomfort (1 case) after the thrombin injection. All these side effects were transient and improved several hours later. CONCLUSION: All the iatrogenic pseudoaneurysms were treated successfully with an ultrasound-guided percutaneous thrombin injection. There was a high rate of hypersensitivity to the bovine thrombin, which precaution should be taken to prevent more serious side effects.
