Abstract
This study reports a case of severe atherosclerosis of the radial artery encountered during raising of a radial forearm free flap in a 56-year-old head and neck diabetic patient which ...precluded the use of the flap. This is a condition which most reconstructive surgeons are not aware of.
Background. A definitive diagnosis of malignant pleural effusion (MPE) is reached by cytological or histological assessment, but thorough analysis of the ultrasound features of the effusion as well ...as pleural thickening or nodularity can also be of significant diagnostic help. Objective. To assess the relationship of specific ultrasound characterisctics and macroscopic features of confirmed malignant pleural effusion, thus increasing the diagnostic potential of thoracic ultrasound. Methods. The findings of thoracic ultrasonography performed prior to initial thoracentesis in 104 patients with subsequently confirmed malignant pleural effusion were analyzed with regard to the macroscopic features of the pleural effusion. Results. Distribution in terms of frequency of hemorrhagic/sanguinolent (n=64) in relation to nonhemorrhagic transparent/opaque (n=40) MPE, regardless of their ultrasound characteristics, did not yield a statistically significant correlation (p=0.159). Conversely, the frequency distribution of hemorrhagic pleural effusions (n=8) in relation to nonhemorrhagic effusions (n=1), in the group of septated MPE, showed a statistically significant difference (p<0.001). The least number of patients (0.96%) had a complex septated MPE combined with the macroscopic appearance of a serous/transparent nonhemorrhagic effusion, which suggests that this combination is a sporadic occurrence and may have a diagnostic significance for this patient group. Conclusion. The incidence of specific combinations of the ultrasound characteristics and macroscopic appearance of MPEs showed different frequency distributions, which may improve the diagnostic value of thoracic ultrasound in this patient population.
Ultrazvuk (UZV) je jedan od najčešće rabljenih modaliteta oslikavanja i navođenja za intervencijske postupke infektivnih bolesti vrata i torakalnih organa. Indikacije za UZV vrata uključuju ...evaluaciju palpabilnih tvorbi vrata, slučajno pronađenih tvorbi vrata i obradu bolesnika s vrućicom nepoznatog porijekla. UZV toraksa je vrijedna metoda u procjeni aktivnosti bolesti perifernog plućnog parenhima, torakalne stijenke, dijafragme i medijastinuma. Oko 50% bolesnika sa sepsom imaju zahvaćen miokard, što je karakterizirano biventrikularnim uvećanjem, reduciranom kontraktilnošću i dijastoličkom disfunkcijom, što se može utvrditi UZV-om. Ehokardiografija je postala neinvazivna slikovna dijagnostička metoda izbora u bolesnika sa suspektnom endokardijalnom lezijom. Pokazala se korisnom ne samo za prikaz vegetativnih lezija, već i za detekciju komplikacija endokarditisa kao što su perivalvularni apsces i značajna valvularna destrukcija koja vodi do regurgitacije. Ovaj pregledni članak govori o UZV prikazu različitih patoloških stanja vrata, toraksa i srca, naglašavajući sonografske karakteristike udružene s infektivnim bolestima.

Neurinom ili švanom rijetki je benigni tumor koji potječe od Schwannovih stanica ovojnice živca. To je spororastući, solitarni i inkapsulirani tumor. Može nastati u bilo kojoj dobi, ali najčešće se ...javlja između 30. i 60. godine života. Na glavi i vratu neurinomi se javljaju u mlađih osoba, u dobi od 20. do 30. godine. Citološka je dijagnoza važna zbog odabira pravilnog liječenja, otkrivanja recidiva ili pojave novog neurinoma na drugome živcu. Citološke punkcije mogu se raditi „naslijepo” ili češće pod kontrolom ultrazvuka. Tijekom sedam godina, od 1. siječnja 2007. do 31. prosinca 2013., punktirano je 14 322 pacijenta na Odjelu za kliničku citologiju i citometriju KB-a Dubrava, a samo u 10 (0,07 %) pacijenata postavljena je citološka dijagnoza neurinoma. Najviše punktiranih neurinoma bilo je u području glave i vrata, u sedam pacijenata od njih 10. Retrospektivno smo analizirali preparate i nalaze i odredili točnost citologije uspoređujući citološku dijagnozu s patohistološkim nalazom. U šest je pacijenata patohistološki potvrđena citološka dijagnoza neurinoma. U četiri pacijenta čija je patohistološka dijagnoza bila neurinom, citološka je dijagnoza glasila mezenhimalni tumor u tri pacijenta, a u četvrtog tumor vretenastih stanica, što su sve bile dijagnoze benignih lezija.
This study compared sensitivity and specificity of multidetector-row computed tomography and duplex Doppler ultrasonography in detecting atherosclerotic carotid plaques complicated with intraplaque ...hemorrhage. Carotid plaques from 50 patients operated for carotid artery stenosis were analyzed. Carotid endarterectomy was performed within one week of diagnostic evaluation. Results of multidetector-row computed tomography and duplex Doppler ultrasonography diagnostic evaluation were compared with results of histological analysis of the same plaque areas. American Heart Association classification of atherosclerotic plaques was applied for histological classification. Median tissue density of carotid plaques complicated with intraplaque hemorrhage was 14.7 Hounsfield units. Median tissue density of noncalcified segments of uncomplicated plaques was 54.3 Hounsfield units (p = 0.00003). The highest tissue density observed for complicated plaques was 31.8 Hounsfield units. Multidetector-row computed tomography detected plaques complicated with hemorrhage with sensitivity of 100% and specificity of 70.4%, with tissue density of 33.8 Hounsfield units as a threshold value. Duplex Doppler ultrasonography plaque analysis based on visual in-line classification showed sensitivity of 21.7% and specificity of 89.6% in detecting plaques complicated with intraplaque hemorrhage. Multidetector-row computed tomography showed a very high level of sensitivity and a moderate level of specificity in detecting atherosclerotic carotid plaques complicated with hemorrhage. Duplex Doppler ultrasonography plaque analysis based on visual in-line classification showed a low level of sensitivity and a moderate-high level of specificity in detecting atherosclerotic carotid plaques complicated with hemorrhage.

Chondroid syringoma (CS) is a rare, benign, appendageal tumor with diagnostic feature of myxochondroid stroma supporting eccrine and apocrine epithelial structures. The usual presentation is a ...painless, slowly growing mass, typically located in the head and neck region. It usually affects middle-aged and older male patients. Because of its unremarkable clinical presentation it is often overlooked. It should be included in the differential diagnosis of cutaneous head and neck tumors, especially in middle-aged men. Optimal treatment of CS is total surgical excision. We present a 63 year-old man with a small nodule on the neck with 5 years of duration. The diagnosis was made initially on fine needle aspiration cytology that was performed by ultrasound guidance and confirmed subsequently by histology. FNA cytology may be very useful to determine diagnosis before excision.
