Fibrin glue in the treatment of dorsal hand burns.

This paper analyses two groups of patients with only dorsal hand burns: groups I contains patients with a total of 15 burned hands and group II patients with 12 hand burns. The patients in group I were all treated by full sheet skin grafts using a two-component fibrin glue. Patients in group II underwent the traditional operative treatment without fibrin glue and the same postoperative physical therapy programme. After follow-up periods of 6-11 months (group I) and 12-21 months (group II), we investigated in both groups, grip strength, key pinch, mobility, two-point discrimination and with the Semmes-Weinstein monofilaments. Our results prove that after the respective follow-up periods group I patients developed far better results for two-point discrimination, touch recognition and mobility.

Effect of cerium nitrate-silver sulphadiazine on deep dermal burns: a histological hypothesis.

Although there are excellent clinical results from using cerium nitrate plus silver sulphadiazine in the treatment of deep dermal burns in our burn centre, its mechanism of action remains unexplained. We set up a prospective study to establish a hypothesis which could explain the formation of the typical leathery crust. Burns treated with cerium nitrate plus silver sulphadiazine and silver sulphadiazine alone were compared histologically and metallurgically. Application of cerium nitrate plus silver sulphadiazine on deep dermal burns caused superficial connective tissue calcification with few deep dermal changes. Cerium penetration was low and silver was never detected intradermally. The precipitation of cerium and pyrophosphate destroys the calcification inhibitory function of the latter, creates multiple calcification nuclei and leads to superficial dermal calcification. No calcium was detectable in biopsies from silver sulphadiazine-treated wounds. No major toxicological side-effects were seen during this study. The clinical results were favourable, as have been reported previously.

[Microsurgical reconstruction of the irradiated mandible with deep iliac circumflex flap].

From 1979 to 1988, 30 osteomuscular or osteomyocutaneous free flaps of the iliac crest (revascularized by the deep circumflex pedicle) were used to reconstruct 28 mandibles severely compromised by radiotherapy exceeding 66 Grays. In addition to a perfect graft raising and microsurgical technique, perfect closure of the mucosal plane appears to be an essential factor of success. Over the years, this iliac crest flap appears to improve the radiological appearance of the bone stumps on either side. The procedure therefore appears to be particularly useful in the treatment of advanced radiation osteonecrosis.

Analysis of the pressure perturbation due to the introduction of a measuring probe under an elastic garment.

Attention is drawn to the increase of the pressure on the skin due to the introduction of a measuring probe under an elastic garment. The increase of pressure is explained by looking at the force equilibrium on the transducer. Making some assumptions on the geometry and the conditions that actually prevail at the interface, this mechanical phenomenon is expressed mathematically. Expressions for estimating the order of magnitude of the relative pressure perturbation are derived both for the case of a cylindrical probe and for a thin plate probe with the same curvature as the limb. Thanks to the geometrical assumptions, these expressions are independent of the mechanical properties of the probe and the soft tissue. As in some of these formulas the magnitude of the indentation appears, a measurement is necessary for estimating the error. Other expressions, only taking in account the dimensions of the limb and the probe, give a rougher estimation of the error. It is shown through a few practical examples that the error cannot be disregarded and cannot be calculated precisely, which means that this measuring technique is unreliable. The same mathematical expressions are used to show that pressure paddings effectively increase the pressure. It is also shown that the introduction of an optical fibre under the garment, used in laser Doppler flowmetry, creates an important additional pressure on the skin.

The clinical value of salpingoscopy in tubal infertility.

A specially designed rigid salpingoscope has been developed to allow inspection of the tubal mucosa during laparoscopy. The presence and extent of intratubal adhesion formation can be evaluated more accurately by this technique than by either HSG or laparoscopy. In 22 patients with bilateral hydrosalpinges, an intrauterine pregnancy rate of 59% was achieved in the group of patients with very mild mucosal lesions and absence of mucosal adhesions.

Current concepts of inhalation injury in burn victims.

Twenty patients with bronchoscopic diagnosis of inhalation injury were reviewed. The history of a burn in a closed space was present in 90% of the patients in our study and evidence of orofacial burns in 100%. In four of these patients serum concentrations of human placental alkaline phosphatate (hPLAP) were determined. This protein can be detected in serum with hPLAP specific monoclonal antibody and increased serum levels of hPLAP are found when there is damage of pneumocyt I cells.

Microsurgical reversal of female mechanical sterilization techniques.

This study presents the patient characteristics, the reason for requesting a reversal operation, the surgical technique and pregnancy rates after a microsurgical reanastomosis following a mechanical (ring or clip) method of sterilization in 55 women. A corrected intrauterine pregnancy rate of 90% was obtained. Ectopic pregnancy occurred in 7% of the patients. Human female sterilization presently has a very high probability of being reversible on the condition that a careful mechanical sterilization has been performed.

An experimental study of tubo-ovarian function following restoration of patency in hydrosalpinges.

The recovery of tubal function after restoration of patency in mechanically induced hydrosalpinges was studied in twenty sexually mature rabbits by correlating the morphological lesions of tubal damage and adhesion formation with the ovulatory function, pregnancy rate and nidation index at 2 and 4-8 weeks postoperative intervals. Two weeks after hydrosalpinx correction no implantations occurred although the oviducts had a patency rate of 63% and no or slight adhesions were present. From four weeks after hydrosalpinx correction implantations occurred. Morphological studies showed a partial or complete recovery of mucosal lesions in this group of rabbits. The number of ovulations correlated with the presence or absence of a moderate degree of postoperative adhesion formation.

The video invasion of rehabilitation.

Motivating burned children to participate actively in rehabilitation at the burn unit demands many creative ideas. To avoid resistance from the child towards the exercises, it is important to offer a variety of techniques. A new play technique is outlined here, based on the use of video games, that is capable of motivating and stimulating children of all ages--even the youngest--towards active participation in rehabilitation.

Microsurgery of ovarian endometriosis.

A long-term follow-up study of 92 patients with ovarian endometriosis treated with microsurgical techniques showed that although endometriosis may persist in many patients, only seven patients required repeat ovarian surgery. Microsurgical techniques are to be recommended for the treatment of ovarian endometriosis and the prevention of postoperative adhesive disease of the ovaries.

Vascularised fasciocutaneous flap for reconstruction of the hypopharynx.

The hypopharyngeal mucosa is a thin, pliable lining, which often needs replacement after tumor excision, stenosis and fistulae. The pectoralis major flap (Ariyan and Krizek, 1977) has brought an element of safety and reliability to one-stage pharyngeal reconstruction. The major disadvantage of these flaps is their bulk (2). The vascularised fasciocutaneous flap (especially the radial forearm flap) is a good alternative to be used in pharyngeal repair.

Salpingoscopy versus hysterosalpingography in hydrosalpinges.

A technique of translaparoscopic salpingoscopy is utilized to evaluate the ampullary segment of the Fallopian tube in patients suffering from infertility. Comparison of this technique with hysterosalpingography in a series of 32 patients with hydrosalpinges demonstrates its superiority in the evaluation of the tubal mucosa. This new diagnostic approach allows a more accurate selection of patients for either microsurgical repair, in-vitro fertilization (IVF) or gamete intra-Fallopian transfer (GIFT).

Salpingoscopy: a new pre-operative diagnostic tool in tubal infertility.

Endoscopy of the fallopian tube allows examination of the tubal mucosa in subfertile patients. Clinical and morphological studies have shown a high correlation between the appearance of the tubal mucosa and the ultimate outcome in terms of pregnancies. Salpingoscopy was originally performed during laparotomy for reconstructive tubal surgery. The present study describes the use of a rigid 3 mm telescope passed along the channel of the operating laparoscope to assess the mucosa of the infundibulum and ampullary segment. Lesions of the infundibulum and ampullary segment have been detected in patients with apparently normal tubes on the hysterosalpingogram and at laparoscopy. The extent of the mucosal lesions can be assessed preoperatively in patients with tubal adhesions, tubo-cornual or isthmic lesions and hydrosalpinges.

Impact of facial burns on the family.

At the University Burn Unit in Leuven (Belgium), we have been working for 4 years now with a multidisciplinary reintegration program. Our team consists of a plastic surgeon (head of the unit), a physical therapist, a social worker and a child psychiatrist. We set up family, context-oriented counselling for the families of seriously burned patients. In this paper, we would like to illustrate some aspects of the importance of facial scars in our society as well as the consequences of such scars for the families of patients. These are 2 essential aspects which have to be taken into account so that the counsellors and family do not reach a deadlock. We discuss how this therapy can be applied. Cooperation with the school is a keystone in the application of such therapy. The teacher is involved as a reflection of the feelings of the parents. Via this intermediary they learn how to cope with their feelings and to talk about them. The team has experienced this as an important step in the construction of family therapy.

Reversibility after female sterilization.

The factors influencing the result of reversal of tubal sterilization were investigated in a series of 78 patients who requested this operation during a 5-year period between 1977 and 1982. In the Falope-ring group isthmo-isthmic anastomosis resulted in a 92% pregnancy rate. On the other hand, no pregnancy occurred when the final tubal length after anastomosis was less than 4 cm. Ectopic pregnancy occurred in 5% of the patients.
