A Wedge-Shaped Anterior Hairline Extension Associated with a Tessier Number 10 Cleft

A wedge-shaped anterior hairline extension is a very rare skin manifestation usually associated with congenital anomalies including a Tessier number 10 cleft. Other associated conditions are the Tessier number 9 cleft, the Fraser syndrome, and the Manitoba oculotrichoanal syndrome (MOTA syndrome). The Tessier number 10 cleft features include a coloboma of the middle third of the upper eyelid, and an eyebrow divided into two portions. The medial eyebrow portion may be absent and the lateral portion is angulated vertically, joining the hairline of the scalp. This creates a wedge-shaped anterior hairline extension. Herein we report on a case of a wedge-shaped anterior hairline extension associated with the Tessier number 10 cleft.

Diphyllobothriasis: update on human cases, foci, patterns and sources of human infections and future considerations.

Diphylobothriasis is a well documented disease of humans. On a world scale new infections are reported regularly, especially from Russia and parts of Japan. Globally, new species have been discovered and the etiology of the disease may be changing. Human infections appear to be in decline but it is not clear if the sources of infection are also in decline or if public health awareness has improved. In North America there has been a decline in human cases while in South America an increase in reports from fish, especially salmonids suggests high levels in these fish species. The history of human infections of Diphyllobothrium latum is primarily associated with the consumption of the northern circumpolar distributed pike and percids and is often considered a parasite of humans only. Indeed some researchers believe that D. latum was introduced to North America by northern European immigrants. The more benign human infections of D. dendriticum appears to be primarily associated with salmonids and coregonid fishes and fish eating birds. Although the early cases of diphyllobothriasis in the 1930s in North America came from fish originating in Lake Winnipeg, Manitoba, there was general belief that it was declining in fish populations and therefore of little significance to humans in the area. However, high levels of a plerocercoid in the flesh of walleyes and pike led to rejection of commercially harvested walleye and pike in Manitoba and northern Ontario, Canada, and a financial loss to Aboriginal fishers. D. latum is widely distributed in fishes of Manitoba and is infective to humans where it is not pathogenic and has a life span up to 4.5 years. The distribution and potential infection routes has not changed in a century and is still well established in natural hosts in the boreal regions of North America. Evidence is building for an old pre-European presence in North America, involving the Beringian land bridge and later involvement of susceptible hosts (northern European immigrants).

Studies in esophageal motility: five year clinical experience in a Canadian tertiary care hospital.

A total of 661 esophageal motility studies were performed in 568 patients over a five year period in a tertiary care hospital. Patients referred for investigation generally presented with one of three symptoms: dysphagia, reflux or chest pain. Dysphagia was more closely identified with organic esophageal dysfunction than other symptoms. Normal studies were recorded in 201 instances (30%). Studies demonstrating either a major or minor non-specific motor disorder were found in 380 cases (58%). Achalasia was found in 48 patients who underwent 65 procedures (10%). Scleroderma was diagnosed in 7 patients (1%). Elderly patients were not found to have diminished esophageal function when compared to a young group.
