Flood basalts in associated volcanic rifted margins, such as the North Atlantic Igneous Province, have a significant component of lavas which are preserved in the present day in an offshore setting. A close inspection of the internal facies architecture of flood basalts onshore provides a framework to interpret the offshore sequences imaged by remote techniques such as reflection seismology. A geological interpretation of the offshore lava sequences in the Faroe–Shetland Basin, using constraints from onshore analogues such as the Faroe Islands, allows for the identification of a series of lava sequences which have characteristic properties so that they can be grouped. These are tabular simple flows, compound-braided flows, and sub-aqueously deposited hyaloclastite facies. The succession of volcanic rocks calculated in this study has a maximum thickness in excess of 6800 m. Down to the top of the sub-volcanic sediments, the offshore volcanic succession has a thickness of about 2700 m where it can be clearly identified across much of the area, with a further 2700 m or more of volcanic rock estimated from the combined gravity and seismic modelling to the north and west of the region. A large palaeo-waterbody is identified on the basis of a hyaloclastite front/apron consisting of a series of clinoforms prograding towards the eastern part of the basin. This body was > 500 m deep, must have been present at the onset of volcanism into this region, and parts of the water body would have been present during the continued stages of volcanism as indicated by the distribution of the hyaloclastite apron.

We present a case report of a single lesion of cysticercosis cellulosae, a parasitic infection caused by the larval stage of Taenia solium (pork tapeworm), presenting as a soft tissue swelling of the lower lip. We stress the importance of knowledge about oral manifestations of parasitic infections.

Patients commonly complain of discomfort at the angle of the mouth following tonsillectomy. This can be attributed to trauma sustained during the procedure. A prospective, patient-blinded, controlled trial of 34 tonsillectomies was performed using a protective, plastic oral guard. A blinded observer recorded postoperative pain and clinically evident trauma to the angle of the mouth. The patient group in whom the guard was used had a significantly lower incidence of labial trauma (p<0.002) and complained of pain less frequently (p<0.002) when compared with a control group in whom no guard was used. The use of a protective lip guard during tonsillectomy is recommended.

Canalicular adenoma is a recently classified uncommon salivary gland neoplasm. This biologically benign growth tends to be multifocal and occurs most often in the upper lips of elderly people. Histologically and clinically it differs from the basal cell adenoma, for which it may be mistaken, in a number of ways. Its clinical importance lies in the fact that it may be confused with malignancy. Little information is available regarding the recurrence and long-term follow-up of these tumours, and where available it covers only relatively short periods.

We report the recurrence of a canalicular adenoma after an 11.2 year disease-free period.

Seventy-three patients with lip carcinoma were treated from 1970 to 1988 inthe Otolaryngology Department of the Beilinson Medical Center. The most common histological type was squamous cell carcinoma which occurred in 68 patients; four tumours were basal cell carcinoma and one acinic cell carcinoma. Carcinoma of the lip is more frequent in males. Nevertheless, the frequency of carcinoma in females in our series was substantially higher than the average reported in the literature. Forty-nine patients were treated surgically and 24 patients were treated by irradiation. Analysis of the results among thosetreated by surgery and those treated by irradiation shows a difference in tumour local control which was statistically significant (p = 0.025). Surgical treatment is recommended because of the advantage of tumour margin assessment, avoidance of radiotherapy complications and rapid rehabilitation. Two rare cases of carcinoma of the lip in young patients (age under 20 years) are presented.
