Antifungal susceptibility, species distribution and risk factors associated with mortality of invasive candidiasis in children in Turkey: A six-year retrospective, single-centre study.

Invasive candidiasis (IC) is a life-threatening fungal infection with high morbidity and mortality. In this study, we aimed to investigate the Candida species distribution and antifungal drug susceptibility and to identify the risk factors associated with IC mortality in children. We conducted a retrospective, single-centre study of paediatric IC in patients from a tertiary care hospital in Turkey between January 2013 and February 2019. A total of 56 Candida isolates underwent antifungal susceptibility testing performed by Sensititre YeastOne YO10 panel, and the demographic and clinical data of 65 patients were examined during the study period. The most commonly isolated species was Candida albicans in 30 patients (46%), followed by C. parapsilosis in 25 patients (38%) and C. tropicalis in three patients (5%). According to the antifungal drug susceptibility testing, C. albicans was fully susceptible to fluconazole and the other antifungal agents (100%). None of the isolates displayed resistance to anidulafungin, micafungin, flucytosine, posaconazole, voriconazole or itraconazole. There were low rates of resistance to fluconazole (1.8%), caspofungin (1.8%) and micafungin (1.8%). In addition, 5.3% of the Candida isolates were susceptible in a dose-dependent manner to itraconazole, 3.6% were susceptible to voriconazole and fluconazole and 1.8% were susceptible to anidulafungin. The mortality rate of IC was 15.4%. Thrombocytopenia after IC treatment was significantly associated with mortality in the multivariate analysis. These results, which help determine the species distribution, antifungal susceptibility patterns and risk factors for mortality, could make a significant contribution to the management of these challenging infections, including choosing appropriate empirical antifungal therapy.

Acute myocardial infarction in a young man caused by centipede sting.

It is known that insects can cause various clinical effects such as myocardial ischaemia and hypotension from vasospasm and the myocardial toxic effects of the venom and anaphylaxis. Although myocardial ischaemia resulting from centipede sting has been reported once before, myocardial injury has not. In this report, the authors present the case of a 20 year old male patient bitten by a centipede and admitted to the emergency room with chest pain, abnormal electrocardiographic findings, and increased cardiac enzymes (cardiac troponin T) suggesting acute myocardial infarction.

Surgical repair in ruptured congenital sinus of Valsalva aneurysms: a 13-year experience.

BACKGROUND AND AIM OF THE STUDY: Rupture of congenital sinus of Valsalva aneurysm is a rare cardiac malformation that usually causes reduced cardiac performance. METHODS: Twenty patients (mean age 28.3 +/- 10.7 years; range: 14 to 55 years) with rupture of congenital sinus of Valsalva aneurysm were operated on at our institution between January 1985 and March 1999. The origin of the ruptured aneurysms was the right coronary sinus in 18 patients (90%) and the non-coronary sinus in two (10%). No ruptures were observed originating from the left coronary sinus. The aneurysms ruptured into the right ventricle in 14 patients (70%), into the right atrium in five (25%), and into the left ventricle in one patient (5%). Subarterial ventricular septal defect (VSD) was the most common associated defect (30%), and aortic insufficiency the second (20%). No correlation was found between subarterial VSDs and aortic insufficiency (p > 0.05). To achieve repair, the aorta and cavity into which the aneurysm had ruptured were opened. The aneurysmal sac was excised and the defect closed with a patch in 18 patients, and without patch in two. RESULTS: One patient died in hospital (mortality rate 5%); no late mortality was observed. Surviving patients were followed up for 4.4 +/- 3.3 years (range: 1 to 13 years). The actuarial survival rate was 95% at 12.35 years. Recurrence of fistula was observed in one patient (5%) in whom the ruptured aneurysm had been closed by primary suture without the use of a patch. At 12.35 years, the actuarial freedom from recurrence of fistula was 94.74% for all survivors, and 100% for patients with patch closure. No late complications have been observed. CONCLUSIONS: Following diagnosis of ruptured sinus of Valsalva aneurysm, surgical repair is the treatment of choice. Surgery performed as rapidly as possible after diagnosis in general leads to an excellent outcome.

Comparison of two surgical techniques for carotid endarterectomy: conventional and eversion.

BACKGROUND: The role of carotid endarterectomy for the treatment of atherosclerotic carotid bifurcation disease is now well established. The aim of this study was to compare durability, postoperative death, stroke, minor strokes, cranial nerve injuries, neck hematomas, myocardial infarctions, or surgical defects and restenosis at the operative site following short- and mid-term duration of the advantages eversion carotid endarterectomy (E-CEA) compared to conventional carotid endarterectomy (C-CEA). PATIENTS AND METHODS: Between March 2003 and November 2012, primary CEAs were performed in 380 consecutive patients by the same surgical groups. These patients were evaluated retrospectively. C-CEA was performed in 202 patients, and E-CEA was performed in 178 patients. Carotid duplex ultrasonography was performed in all patients at 1, 6, 12 and 24 months after CEA to identify residual atherosclerotic carotid disease. RESULTS: Mean age was 67.3±13.4 years in the E-CEA group and 64.8±14.8 years in the C-CEA group. Mean cross-clamping time in the E-CEA group was 9.54±2.6 minutes and 12.62±2.7 minutes for C-CEA group (P=0.236). Three postoperative strokes occurred (one after E-CEA and two after C-CEA). In the E-CEA group and C-CEA group respectively, carotid stenosis rates were found in 4 patients (2.24%) and in 5 (2.97%) at a follow-up period of 26 months. CONCLUSION: Classical endarterectomy still remains the gold standard surgical technique for patients who are selected for coronary artery disease surgery. Nevertheless, we believe that eversion endarterectomy, which has some advantages, must be kept in mind as an alternative approach.
