Body mass index and body fat distribution in newly-arrived Vietnamese refugees in Sydney, Australia.

Body mass index (BMI), body fat distribution and some behavioural variables were examined in an ethnic Vietnamese population newly arrived in Australia. The age range was 23 to 74 years for males (n = 246, mean = 38.8) and 24 to 66 for females (n = 165, mean = 36.4). Mean BMI was 20.62 +/- 2.65 (male) and 21.25 +/- 3.16 (female). Waist-to-hip ratio (WHR) was 0.844 (males) v 0.802 (females), p < 0.0001: waist was 73.7 cm (males) v 71.7 cm (females), (p = 0.007). Male smoking was 69%, female, 1%; the BMI of male non-smokers was higher than that of smokers 21.22 v 20.35 (p = 0.0017). Exercise patterns, diet or alcohol intake did not appear to affect BMI. The mean BMI of this refugee Vietnamese population is low by comparison with the Australian population. Vietnamese females although of lower mean BMI, have higher WHR than Australian females.

Cavernous branches of the internal carotid artery: anatomy and nomenclature.

In most standard anatomical textbooks, the cavernous branches of the internal carotid artery (ICA) are rarely or shortly described. Among three reports dealing with these branches, there is a lack of agreement in description and nomenclature. This study presents a systematic nomenclature based on the result of anatomical dissection in the cavernous sinus (CS) of 32 human subjects. The ophthalmic artery was found arising inside the CS in 5 subjects (15.6%). The posterior trunk (meningohypophyseal trunk of Parkinson) was present in all subjects (100%), but its distribution varied considerably. In 9 subjects, one or two of its primary divisions originated directly from the ICA. The lateral trunk was found in 21 subjects (65.8%), and the capsular arteries of McConnell of the median group were found in 9 (28.1%). Other branches to the surrounding structures (trigeminal ganglion and divisions, superior wall of the CS, the 3rd, 4th, and 6th cranial nerves, and osseous branches) were inconstant. Anastomotic branches to the ophthalmic, middle meningeal, and ascending pharyngeal arteries were also noted. A systematic nomenclature is proposed, in which the branches of the ICA are named according to their topographical origins from the artery and their primary or secondary divisions are named according to their destinations.

The absence of the internal carotid artery: report of two cases.

The absence of the internal carotid artery (ICA) is a very rare anomaly. Since the first description of the condition in 1787, only 60 cases have been reported in the literature. We report two cases of absence of the left ICA amongst 2195 carotid angiograms performed in the Department of Neuroradiology at the Royal Brisbane Hospital over a period of 4 years. The first patient was suffering from obstructive hydrocephalus; the second from right cerebellopontine angle syndrome. Cerebral angiography by catheterization of the aorta revealed the absence of the left ICA. The collateral circulation to the left cerebral hemisphere was provided by the vertebrobasilar system via a dilated left posterior communicating artery. In the first patient, the absence of the ICA was coincidental with other congenital anomalies of the cervico-occipital junction. In the second patient, the dilated vertebrobasilar system was responsible for compressing the right cranial nerves VII and VIII. It is emphasized that in some cases of cerebellopontine angle syndromes, thorough investigation of the cerebral vessels is necessary.

The accessory middle cerebral artery--a variant of the recurrent artery of Heubner (A. centralis longa)?

Three accessory middle cerebral arteries are described in two out of 75 brains dissected under the operating microscope. Each artery originated from the anterior cerebral artery, lateral to its junction with the anterior communicating artery, followed the proximal segment (A1, pars precommunicalis) of the anterior cerebral artery, then the horizontal portion (M1, pars sphenoidalis) of the middle cerebral artery towards the lateral sulcus. Each supplied the lateral orbital gyrus, the gyrus longus of the insula, part of the putamen, the head of the caudate nucleus and the anterior limb of the internal capsule. The presence of the accessory middle cerebral artery is discussed with regard to the recurrent artery of Heubner (A. recurrens, A. centralis longa).

Association of intracranial aneurysm and arteriovenous malformation.

In a series of 252 patients (47 with arteriovenous malformation, 205 with aneurysms), two patients had a coexisting intracranial aneurysm and an arteriovenous malformation. In one patient, the aneurysm was proximal to the main feeding arteries of the arteriovenous malformation. In the other patient, there was no anatomical relationship between the two lesions. These findings illustrate different views on the pathogenesis of the rare association of the two conditions.
