Kalvarium Metastazı Ayırıcı Tanısında Enostoz: Olgu Sunumu
Enostozlar (kemik adaları), genelde insidental olarak bulunan, herhangi
bir klinik şikayet yaratmayan kemik lezyonlarıdır. Ayırıcı tanılarında primer
kemik tümörleri ve metastazlar mevcuttur ve tanıya yönelik çalışmalarda
kafa karıştırıcı olabilmektedirler. Olgu sunumumuzda metastaz ön tanısı ile

Short-Term Prognostic Value Of Rest Tc99M-Mibi Gated Spect After Acute Non-Q Wave Myocardial Infarction
Aim: The purpose of this study is to determine the short–term
prognostic value of technetium 99m methoxyisobutylisonitrile gated
single photon emission computed tomography (Tc99m–MIBI Gated
SPECT) in patients with acute Non–Q wave myocardial infarction
(NQMI) in 30 days. Methods: We identified 36 patients who underwent
rest Tc99m–MIBI Gated SPECT and who were followed-up
30.65±0.49 days after first a NQMI. 21 patients were males, 15
females, with a mean age of 60.30±10.17 years. Rest
Tc99m–MIBI Gated SPECT were performed within 48 (30.7±2.3)
hours of admission to the coronary care unit after acute myocardial
infarction (MI). The left ventricular ejection fraction (LVEF), end
diastolic (EDV) and end systolic volumes (ESV), and summed rest score
(SRS) and extent score (ES) were assessed using rest Tc99m–MIBI
Gated SPECT. Results: Rest Tc99m–MIBI Gated SPECT parameters
and clinical datas were analyzed and divided two group according to
prognosis, as new cardiac event (poor prognosis) and stable stuation
(good prognosis). During follow-up, 12 patients (33%) had a new
clinical event, [4 congestive heart failure (11%), 7 revascularization
(19%) and 1 reinfarct (2%)], whereas 24 patients (66%) showed a good
outcome. There were significant differences LVEF, EDV, ESV, SRS and ES
values between poor and good prognosis group (p=0.011, p=0.016,
p=0.017, p<0.001, p<0.001 respectively). The hazard ratio for new
cardiac events were 7.6 for patients with rest LVEF lower than 40%
(Relative Risk (RR)=7.66, Confidence Intervals (CI) 1.60 to 35.90,
p=0.005), for ESV>70 ml (RR=5.31, CI 1.17 to 24.14, p=0.027),
SRS≥7 (RR=7.00, CI 1.25 to 39.14, p=0.032) and ES≥3
(RR=6.59 CI 0.72 to 60.02, p=0.037). Conclusion: Left ventricular
parameters (LVEF, ESV) and perfusion scores (SRS, ES) which obtained by
rest Tc99m–MIBI Gated SPECT, provide useful information in the
prediction of future cardiac events after NQMI in 30 days
