Operative treatment of solitary bone cysts with tricalcium phosphate ceramic. A 1 to 7 year follow-up.

From 1984 to 1990 we treated 18 patients aged 5 to 15 1/2 years with solitary bone cysts of the humerus, the femur and the calcaneus. To fill the defect, tricalcium phosphate (TCP) instead of bone grafting was used. The clinical and radiological long-term results up to seven years postoperatively are reported. In 16 patients TCP was well incorporated without any adverse reaction to the synthetic material. Two patients with a recurrence of the bone cyst were successfully reoperated. We conclude that ceramics are a cheap and easy available substitute for bone grafts in the treatment of solitary bone cysts.

[Ambulatory pediatric surgery].

The authors refer about their experience in ambulatory pediatric surgery performed in pediatric clinics or in their own practice. Indications are listed, conditions, advantages and disadvantages are discussed. 562 operations were completed from February 1991 to January 1992, 181 (32%) under practice conditions with an experienced anesthesiologist. No complications had to be reported, and no patient was hospitalized due to surgical or anesthetic complications. But indications for ambulatory surgery have to be strictly noted, and only children in excellent health should be anesthesized. The decision about operability has to be made by the anesthesiologist in charge.

Cranioplasty for acquired skull defects in children--a comparison between autologous material and methylmethacrylate 1974-1990.

The authors report on their experiences with 21 patients with skull defects which were closed by polymethylmethacrylated plates (PMMA) from 1974 to 1990 at the University Children's Hospital in Zurich and the "Gemeinschaftspraxis fuer Kinderchirurgie". The results were compared with 15 cases treated by autologous grafts. Because of false indication, one case of PMMA-plasty led to an infected fistula. Otherwise no adverse reactions were noted. Three of the 15 cases with autologous grafts showed resorption. Polymethylmethacrylate is an excellent agent for skull reconstruction. The simple procedure, shorter OP time, and lack of pain or disfigurement due to a donor site signify a great advantage to this method.

[Intra-articular finger fractures in children].

From 1982 to 1984 140 patients with fractures of the fingers were admitted to the department of surgery of the University Children's Hospital. Only 28 patients (21.5%) suffered from intraarticular fractures. Three 3/12 years later, 10 patients (35.7%) presented functional trouble or suffered from pain. Only 2 of the 15 conservatively treated patients had trouble. On the other hand, 8 children out of the 13 operatively treated patients presented an unsatisfactory result. Localisation, type of fracture and kind of treatment are analysed. We prefer as a rule conservative treatment excepting fractures of type Salter III and IV, osseous ruptures of the ulnar collateral ligament of the thumb and dislocated fractures. We suggest splinting with 0.6 mm K-wires.

[Congenital hydrocephalus--preoperative assessment and intraoperative findings in congenital hydrocephalus].

54 children already presented in Part 1 were analysed with regard to their preoperative aetiopathological findings and evolution of different parameters until surgery. Our interest was focussed on possible correlations between brain malformation and head circumference as well as both ICP and neurological evolution. We examined the presence of infectious diseases in the preoperative period and checked on the advantage of a perioperative antibiotic therapy. We could not find any correlation between the aetiopathological findings in X-ray investigation and head circumference or ICP or preoperative neurological findings. Perioperative antibiotic therapy does not seem to be an additional safety factor.

Deleterious consequences of gastroesophageal reflux in cleft larynx surgery.

Our series of 17 children with laryngotracheal clefts is reported. In three of four cases with a complicated postoperative course, gastroesophageal reflux (GER) has been found. Three breakdowns of the surgical repair opposed to be due to GER. Only one child with a cleft type III died, although a mortality rate of 93% is reported in the literature. GER has to be excluded before tracheoesophageal cleft surgery is undertaken.

[Bone replacement using beta-tricalcium phosphate--results of experimental studies and initial clinical case examples].

Beta-Tricalcium phosphate granulates (Ceros 82) implanted in femurs of the rat led to osteoconduction already one week after implantation. Compared to the problems of autologous implants, TCP presents many advantages: No operation on the donor site, no limitation of quantity, clinically negligible resorption, immediate osteoconduction. The results on femoral defects of 26 rats filled up by beta-TCP and our first clinical experiences on juvenile bone cysts are presented.

[In vitro studies on Geliperm Dry as a vehicle for antibiotics and antiseptics in local burn therapy].

Geliperm is a synthetic skin substitute, consisting of polysaccharid-polyacrylic plates. It is available as a soaked or a dried form (Geliperm dry). Geliperm dry can be soaked in antibiotic or antiseptic solutions. The in vitro inhibition of bacterial growth has been measured. The optimal concentrations have been evaluated. Geliperm dry soaked in antibiotic or antiseptic solutions can be used in the treatment of burns, but does not replace early excision of burned tissue or infected necrosis.

[Isolated scalds and burns of the hands in early childhood].

Every year about a hundred children with burns and scalds are hospitalised in the Burns Unit of the University Children's Hospital in Zürich. 15% of these patients are children between 1/2 to 4 years old with isolated burns and scalds of their hands. The experience gained in the treatment of 53 such children during 4 years is described. The burn healed spontaneously in 31 patients; in 22 cases Thiersch grafts had to be used. In the follow-up treatment compression suits and special splints to prevent secondary contractures were employed. The results of this treatment using splints and compression suits are discussed.

[Early rehabilitation and psychosocial problems of burns in childhood].

In the management of burns in childhood teamwork is even more important than in the treatment of other traumatic injuries. The authors describe their experience with more than 600 children referred to the center for burns of the University Children's Hospital, Zurich, between 1 November 1977 and 31 December 1982. The psychological state of the child during hospitalisation and the question of somatic and psychic reintegration into the community are very closely connected. 1. Early rehabilitation: The authors describe technical possibilities in the treatment of scars in children and stress the risks involved and possible mistakes. 2. Psychological problems: Recovery depends to a large extent on the reactions by the medical and nursing personnel. The difficulties which will be encountered if children are treated in a hospital not specialized in the treatment of burned children, are described and the indications for transfers of those children to specialized children's units are enumerated.

[Comparative in vitro tests of silver sulphadiazine and zinc sulfadiazine swabs on burn patients].

The antibacterial effect of silver sulphadiazine is compared with that of zinc sulphadiazine in three in vitro tests with 14 different bacterial colonies. Our results demonstrate that silver sulphadiazine is more efficient than zinc sulphadiazine as an antibacterial agent. As the local application of zinc promotes and accelerates wound healing, we suggest to apply first silver sulphadiazine and then zinc sulphadiazine in combined local therapy of burn wounds.
