We report a case of a 21-year old male with an asymptomatic solitary costal exostosis incidentally detected on a chest X-ray. The exostosis originated from the costochondral junction of the left fourth rib and protruded into the thoracic cavity. Exploratory thoracoscopy showed that the exostosis had scratched the adjacent pericardium and visceral pleura. A 5.5-cm long rib segment including the ...

The haloarchaeon Haloferax mediterranei has shown promise for the economical production of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), a desirable bioplastic. However, little is known at present about the genes involved in PHBV synthesis in the domain Archaea. In this study, we cloned the gene cluster (phaEC(Hme)) encoding a polyhydroxyalkanoate (PHA) synthase in H. mediterranei CGMCC ...

The described case is of a 15-year-old boy who presented with a persistent hiccup and repeated episodes of left-sided chest pain. At computed tomography scan an exostosis originating from the costo-chondral junction of the left 4th rib was seen. The tip of the exostosis reached the external surface of the pericardium. Removal of a 2 cm rib segment including the implantation basis of the exostos...

BACKGROUND We studied an unusual combination of severe short stature, mesomelia (Leri-Weill dyschondrosteosis syndrome), and multiple exostosis in several family subjects over three generations. The pattern of inheritance was compatible with autosomal dominant. METHODS Of 21 affected members over three generations, shortness of stature, associated with mesomelia resembling Leri-Weill dyschond...

Osteochondromas are the most common benign bone tumors. Usually solitary, multiple osteochondromas (exostoses) are seen in patients with Multiple Hereditary Exostoses (MHE). Chondromatous transformation of lumbar osteochondroma in a patient with multiple exostoses is a rare phenomenon. We present a rare case of secondary chondrosarcoma of lumbar exostoses with patient presenting with symptoms o...

Subungual exostosis is a benign calcifying projection that occurs on the distal phalanx beneath or beside the nail. The problems in treatment are frequent postoperative recurrence and nail deformity or loss. Here, we describe the case of a male patient with a subungual exostosis beneath the proximal region of the nail plate of the right big toe. A precise preoperative evaluation of the anatomic...

The antiglioma activity of elliptinium (HME) was investigated in a human glioma clonogenic cell assay. Early passage cells of three human glioma cell lines (SF126, SF375, and SF407) were exposed to HME at the clinically achievable dose of 3 microM for 3 h. At this HME concentration, clonogenic cell survival was reduced by more than 3 logs in SF126 and SF375, and by 0.8 logs in SF407. A study of...

Osteochondromas represent the most common primary bone tumours; they reportedly represent 20-50% of all benign bone tumours and 10-15% of all bone tumours. Malignant transformation is their most severe complication. However, deformities and interference with major joint function are the most frequent complaints in patients with hereditary multiple osteochondroma. Treatment should therefore aim ...
