Impasse in the management of recurrent basal cell carcinoma of the skull with sagittal sinus erosion

2015

Abstract Basal cell carcinoma (BCC) is a non melanocytic skin cancer that arises from basal cells, affecting commonly fair-skinned human beings. Although the tumor is well known for local recurrences, extension into the intracranial space is reported. A case of a giant BCC of the scalp invading the middle and posterior third of the superior sagittal sinus (SSS) is reported. A 70-year-old male with a basal cell carcinoma history presented with a massive bleeding from the SSS invaded by the tumor. Since the patient refused surgery the bleeding was managed through direct compression by applying a thrombin-based hemostatic agents and sterile dressings. This procedure was performed daily in orde…

Hearing loss in facioscapulohumeral dystrophy.

1986

Bilateral sloping high frequency hearing loss of 20–90 dB was found in six out of ten patients with infantile or adolescent onset FSHD. In all cases the basic defect could be traced to the cochlea. The outer hair cells of the basal turn are predominantly affected. In 20 patients with various other forms of muscular dystrophy or neuromuscular disorders with an FSH distribution, no sensorineural hearing loss was found. Myopathology of FSHD patients extended from mild to severe, often showing inflammatory infiltrates and type I fibre atrophy, without unequivocal differences between the two groups with and without hearing loss. It is concluded that cochlear dysfunction is a specific and frequen…

The late Late Albian (Mortoniceras fallax Zone) cephalopod fauna from the Bracquegnies formation at Strépy-Thieu (Hainaut, southern Belgium).

2016

Excavations in 1989-1990 for the construction of a boat lift near the villages of Strépy and Thieu, east of Mons (province of Hainaut, southern Belgium), exposed a 40-metre section of the Bracquegnies Formation (Haine Green Sandstone Group; the ‘Meule de Bracquegnies’ of previous authors). Several hundred well-preserved, silicified cephalopods were collected from between 15 and 35 metres above the base of the sequence temporarily exposed there. The fauna is: Eutrephoceras clementianum (d’Orbigny, 1840), Puzosia (Puzosia) mayoriana (d’Orbigny, 1841), Callihoplites tetragonus (Seeley, 1865), Discohoplites valbonnensis valbonnensis (Hébert & Munier-Chalmas, 1875), Cantabrigites cantabrigense S…

The genome sequence of Blochmannia floridanus: Comparative analysis of reduced genomes

2003

Bacterial symbioses are widespread among insects, probably being one of the key factors of their evolutionary success. We present the complete genome sequence of Blochmannia floridanus , the primary endosymbiont of carpenter ants. Although these ants feed on a complex diet, this symbiosis very likely has a nutritional basis: Blochmannia is able to supply nitrogen and sulfur compounds to the host while it takes advantage of the host metabolic machinery. Remarkably, these bacteria lack all known genes involved in replication initiation ( dna A, pri A, and rec A). The phylogenetic analysis of a set of conserved protein-coding genes shows that Bl. floridanus is phylogenetically related to Buch…
