Mycobacterium chelonae is a rapidly growing nontuberculous Mycobacterium and an uncommon cause of aggressive, treatment-resistant ocular and periocular infection. This is the first known case report of a woman who developed unilateral M. chelonae dacryocystitis after undergoing endoscopic sinus surgery and right endoscopic dacryocystorhinostomy (DCR) with Crawford stent placement. We describe o...

Congenital absence of lacrimal puncta may be an isolated finding or associated with other developmental abnormality. Nasolacrirnal ducts can be absent thus predisposing to the formation of a congenital lacrimal mucocele. Punctal and canalicular agenesis is very rare. Four percent of new patients attending the lacrimal clinic at Moorfields Eye Hospital, London, UK. from 1981 to 1990 inclusive we...

To report a rare case of a 19 year old female presenting with bilateral dacryocele and punctal and canalicular agenesis without epiphora. After clinical and radiological examination, the patient was found to have bilateral lacrimal gland agenesis as well. No other dental, otological or systemic abnormality suggestive of lacrimo-auricular-dento-digital syndrome was detected. She was managed with...

Close inbreeding has often been shown to be extremely harmful because of the fixation of deleterious recessive alleles in inbred offspring (Charlesworth & Charlesworth 1987). As a consequence, inbred offspring often show reduced fitness compared with outbred offspring (inbreeding depression, Charlesworth & Charlesworth 1987). The ability to identify relatives (kin recognition, Hepper 1991) offe...

This paper identifies pivotal factors behind individual decision making in the transition from high school to post-secondary education in the Netherlands. We apply a multinomial logit framework to individual data and accommodate two types of effects that have not received much attention in the literature. First, we analyse the impact of geographical accessibility of the higher education system....

While many welcomed the fact that the US was now on board the climate negotiations, environmental groups and many scientists warned that the agreement was weak an...

My colleague Professor John Cherrie once said that we know more about the number of birds breeding in British meadows each year (see http://jncc.defra. gov.uk/pdf/BBSreport12_web.pdf) than the number of workers exposed to carcinogens in the workplace. It is clearly important to monitor bird populations, but I would consider it of at least equal importance to know what hazardous agents workers a...
