Surgical Anatomy of the Inguinal. Region: Implications during Inguinal Laparoscopic Herniorrhaphy - Totté, E.; Van Hee, R.; Kox, G.; Hendrickx, L.; VAN ZWIETEN, Koos Jaap
Introduction: In laparoscopic inguinal hernia repair the
inguinal region is approached and hernia repair performed
from the interior side instead of the classical
open external access. Exploration and placement of staplers
in the internal inguinal region during laparoscopic
hernia repair may sever different anatomical structures,
or induce specifi c complications such as nerve entrapment,
neuralgia, hematomas or osteitis. The incidence
of these complications may be reduced by careful dissection
of the preperitoneal tissues and by placing a
prosthetic mesh without the use of stapling. As laparoscopic
techniques evolved, different sizes of meshes
have been used. An exact determination of mesh size
was hitherto not investigated. Aim: Cadaver studies of
the topography of blood vessels...

Observations in proximal interphalangeal flexion of the finger - VAN ZWIETEN, Koos Jaap; LIPPENS, Peter; GELAN, Jan; ADRIAENSENS, Peter; Thywissen, C.; Gens, F.
The extensor assembly of the finger, consisting of tendon fibers from extrinsic and intrinsic finger muscles, rearranged into one medial bundle and two lateral bundles, undergoes distal displacement during proximal interphalangeal flexion. The lateral bundles, conjoining distally into one terminal extensor tendon for the distal phalanx, lie slack alongside the flexed proximal interphalangeal joint (Landsmeer, 1976). The distal phalanx becomes loose, thus allowing simultaneous distal interphalangeal flexion.
During unresisted flexion of the proximal interphalangeal joint of the finger, without simultaneous distal interphalangeal flexion, the phenomenon of the floating distal phalanx can be observed (Tubiana et al., 1996).

Foot muscles preventing inversion traumatisms - VAN ZWIETEN, Koos Jaap; ROBEYNS, I.; VANDERSTEEN, Marjan; LIPPENS, Peter; MAHABIER, Roberto; LAMUR, Kenneth
Biomechanical analysis based on in vitro measurements of anatomical specimens of the foot, to evaluate theoretically the efficiency of foot muscles in the prevention of inversion traumatisms, during normal walking and running, as well as in sports, e.g. tennis.

The extensor assembly of the finger in lower primates - VAN ZWIETEN, Koos Jaap
Definition of the order Primates, and sub-groups thereof, is intimately linked to phylogenetic
reconstruction. It is also beset by similar problems, notably those of identifying derived similarities and of avoiding circular reasoning. Inclusion of tree-shrews in definitions of living primates and inclusion of Plesiadapiformes in definitions of living and fossil primates are best avoided initially, as both are controversial. For various reasons, it is helpful to define living primates (excluding tree-shrews) first and then to consider as separate issues: (1) the relationships of tree-shrews, and (2) the inclusion of particular fossil groups in the order Primates. Previous definitions of living primates...

Changes observed over time in dentin developent after neonatal desensitisation - Seltman, Marion; Krage, Tracy; Zanger, K; STRUYS, Tom; LAMBRICHTS, Ivo; Raab, W
The neonatal application
of capsaicin has been known to produce a
selective desensitisation of nociceptive fibers in
a physiological system [1, 2]. Additionally, it
has been observed that a lack of functional
nociceptive fibers in the pulp has a detrimental
effect on dentine development after 120 days
[1]. The purpose of this study was to observe
dentine development in the neonatally
capsaicin-treated rat in a spectrum from 30 to
155 days of life.

Metallothionein: a possible new marker for human dental pulp stem cells - STRUYS, Tom; Krage, Tracy; MARTENS, Wendy; THEUNISSEN, Evi; MOREELS, Marjan; LAMBRICHTS, Ivo
Human dental pulp stem cells (HDPSCs) is a term used for the remaining mesenchymal stem cell population in adult teeth. It has already been described that these cells exhibit odontogenic capacities when these cells are explanted into immunocompromised mice. They create a dentin-pulp like complex and in this way their use in tissue engineering and tooth regeneration seems very promising. However, there is still a lack of specific markers to identify this cell type. In this study, we investigated the immunoreactivity of HDPSCs for metallothionein (MT), a Cystein-rich, low molecular weight protein. MT has the capacity to bind both physiological...

Filosofische en godsdienstige invloeden op de ontwikkeling van de geneeskunde - VAN ZWIETEN, Koos Jaap
In 1455 presenteerde Gutenberg zijn eerste gedrukte teksten te Frankfurt de boekdrukkunst had zijn intrede gedaan. Enkele decennia later werd, voor het eerst in de Lage Landen, een lijst van verboden boeken gepubliceerd. Hiermee ontstond een beweging die het openbaar maken van nieuwe vindingen belemmerde. Dergelijke trends zijn ook nu nog aanwijsbaar, als men bijvoorbeeld denkt aan pogingen om de informatiestromen van het Internet te beheersen.
In deze lezing wordt ingegaan op de ondervonden moeilijkheden bij het verspreiden van enkele nuchtere, nieuwe waarnemingen, die met name werden gedaan in de medische wetenschappen.

The spinal dermal-sinus-like stalk - van Aalst, J.; BEULS, Emile; Cornips, E. M. J.; van Straaten, H. W. M.; Boselie, A. F. M.; Rijkers, K.; Weber, J. W.; Vles, J. S. H.
In this study, a disjunction anomaly mimicking the spinal congenital dermal sinus (DS) is described. This anomaly is referred to as the dermal-sinus-like stalk. Dissimilarities between a true dermal sinus and a dermal-sinus-like stalk are discussed. Three cases in which a spinal congenital dermal sinus was suspected are presented. A similar anatomical configuration, different from that of a dermal sinus, was found. All cases presented with a skin-covered dimple from which a solid tract was seen continuing intramedullary in two cases and intraspinally in one case. None of the patients presented with signs of infection or an associated dermoid-epidermoid tumor....
