Human eruption is a unique developmental process in the organism. The aetiology or the mechanism behind eruption has never been fully understood and the scientific literature in the field is extremely sparse. Human and animal tissues provide different possibilities for eruption analyses, briefly discussed in the introduction. Human studies, mainly clinical and radiological, have focused on norm...

we describe, the first case of phenobarbital-induced dress syndrome presenting as a lichenoïd eruption. a 49-year-old man had received phenobarbital for a cerebral metastasis. twenty-five days later, he developed a purplish skin eruption, odynophagia, oral mucosal erosion and fever. physical examination revealed a cervical lymphadenopathy and facial edema associated to a diffuse violaceous macu...

The malposition of a self-expandable metal stent (SEMS) placed fully inside the bile duct may be disastrous, and adjusting the position of a malpositioned stent can be difficult or impossible. Fully-covered SEMSs were designed mainly to treat benign biliary strictures and to be removable [1]. The removal process can however be difficult if the stent is placed fully inside the bile duct. Graspin...

Biopsy specimens of the small bowel were obtained from 40 patients suspected of having malabsorption. Four different techniques were used at a single session--namely, endoscopic biopsy of the descending duodenum using paediatric and standard size forceps and suction capsule biopsy of the descending duodenum and the proximal jejunum. Specimens were compared for size, adequacy, and ability to con...

BACKGROUND The decreased morbidity and rapid recovery after thoracoscopic lung biopsy compared with open lung biopsy by thoracotomy is increasingly recognized, as is the ability to obtain satisfactory diagnostic material thoracoscopically. To our knowledge, however, there has been no systematic comparison of specimen quality using different thoracoscopic biopsy techniques. The purpose of this s...

An endoscopic transpapillary mapping biopsy is useful for evaluating intraepithelial tumor spread in bile duct cancers [1,2]; however, it is occasionally technically difficult to advance the biopsy forceps through a biliary stricture. Here, we describe the case of a patient with a hilar biliary stricture who underwent a selective mapping biopsy. The biopsy technique described is suitable where ...

A new species of the genus Caenis Stephens is described based on the male imago, female imago and egg stages from the state of Rio Grande do Sul, Brazil. The male imago of Caenis gaucha sp. nov. is diagnosed as follows: body length of male 2.0-2.5 mm; base of antennal flagellum not dilated; forceps apically rounded, not fused to lateral margins of styliger plate; styliger plate short with poste...

To achieve upward retraction of the iris when applying forceps to the upper part of the lens capsule for intracapsular cataract extraction Verhoeff used a lip on one blade of the forceps. The instrument shown in Fig. 1 so retracts the iris that a better view is obtained of the upper part of the lens capsule for application of Arruga's capsule forceps than is possible when using Verhoeff's lippe...

Introdouction:Tooth eruption is recognized as an important aspect of human growth and development. It can be influenced by a number of factors, and it may reflect the general development of a child’s body. The purpose of this study was to determine the age at which the first primary tooth erupted and its relationship with height, weight and head circumference in 3-15-month children in the...

When a load is added to the tip of a wire actuated robotic forceps, tracking accuracy of the forceps is degraded due to the elastic elongation of the wire. In this paper, for the wire actuated robotic forceps, a new algorithm that can estimate a reaction torque and an amount of elongation of the wire, is proposed. By compensating for amount of elongation of the wire, track ability of the forcep...
