Fricke supraorbital flap for reconstruction of total lower eyelid defects

Summary Split or full thickness eyelid defects resulting from tumor destruction or surgical excision present a dilemma for plastic and reconstructive surgeons. Full thickness eyelid replacement requires composite grafting of the skin, together with tarsal support of its substitute and mucosa. The flap described by Fricke in 1829 was used for reconstruction of anterior lamella in six lower eyelid defects. In three of our cases chondromucosal grafts taken from nasal septum were utilized for posterior lamella repair. The results have been satisfactory from a functional and cosmetic standpoint.     

Acute leukaemia in a defined geographic area – Incidence,clinical history and prognosis

A consecutive series of patients (1978–1981) comprising all patients with acute leukaemia from a population of 475000 inhabitants was reviewed. Thus, 94 patients were diagnosed as having acute leukaemia. No patients were lost from follow-up. The incidence figures of ALL and AML differed significantly from those of Sweden as a whole. 9 patients were < 15 years old. The median age of adult patients was 64 years, 60.8% being ≥ 60 years old. Of adult patients with AML, 20% had a preleukaemic history (chronic myeloproliferative disorders, myelodysplastic syndromes and others). None of 6 patients with leukaemia as a metamorphosis of a chronic myeloproliferative disorder achieved a complete remission. The overall remission rate of the remaining adult patients was 25%. Treated patients, 15–39 years old, with AML without any preleukaemic history, had a complete remission rate of 80% compared to 12% for patients ≥ 60 years old with the same diagnosis. Of 60 patients with ‘primary’ AML, 14 were not treated, mainly because of advanced age and complicating diseases. Most of these patients died within a week of admission.     

Effects of growth hormone on glucose and fat metabolism in human subjects.

This article focuses on in vivo data from tests performed in normal subjects and in patients who had abnormal growth hormone (GH) status. Experimental data in human subjects demonstrate that GH acutely inhibits glucose disposal in skeletal muscle. At the same time GH stimulates the turnover and oxidation of free fatty acid (FFA), and experimental evidence suggests a causal link between elevated FFA levels and insulin resistance in skeletal muscle. Observational data in GH-deficient adults do not indicate that GH replacement is associated with significant impairment of glucose tolerance, but it is recommended that overdosing be avoided and glycemic control be monitored.     

Combined use of cryotherapy and diode laser photocoagulation for the treatment of threshold retinopathy of prematurity.

PURPOSE: Cryotherapy and indirect laser retinal photoablation are both effective in the treatment of retinopathy of prematurity (ROP). We describe the safety, efficiency, and effectiveness of combined cryotherapy and diode laser photocoagulation to treat threshold ROP. METHODS: Records of patients developing threshold ROP from January 1, 1996 through December 31, 1998, were retrospectively reviewed to identify those treated with combined cryotherapy and photocoagulation and followed up for at least 45 days postoperatively. Diode laser was used to ablate posterior avascular retina, and cryotherapy was used for anterior retina. Data reviewed included ocular and systemic complication rates, treatment duration, number of laser burns, most recent fundus examination, visual acuity, and refraction. RESULTS: In 13 patients, 23 eyes received combined treatment. No intraoperative complications occurred. Mean duration of anesthesia and treatment was 35 +/- 8 minutes/eye. A mean of 117 +/- 84 laser burns/eye were applied. In 20 of 23 eyes (87.0%), anatomic outcome was favorable at last examination. In 13 of 16 eyes (81.3%), functional (visual acuity) outcome was favorable (visual acuity better than 20/200) at 1 year. At 6 months or later, 14 of 16 eyes (87.5%) measured were myopic, of which 5 (31.3%) were highly myopic (> 6 diopters). CONCLUSIONS: The effectiveness of treating ROP with combined cryotherapy and diode laser photocoagulation compares with that of either modality alone. By decreasing the number of laser applications, combined therapy may be faster and technically easier for eyes with very posterior ROP. This may decrease the number of complications seen when either excessive cryotherapy or laser retinal photoablation is used.     

The restoration of a maxillary central incisor fracture with the original crown fragment using a glass fiber‐reinforced post: a clinical report

Abstract – This report describes an esthetic, conservative, and economical alternative restoration technique for a fractured central incisor using the patient’s own tooth crown piece and a bondable reinforcement glass fiber. Although the long‐term durability of this adhesive post core restoration remains unknown, it remains successful after 1 year.     

Treatment of horizontal root‐fractured maxillary incisors – a case report

Abstract – Traumatic dental injuries often occur to the teeth and their supporting tissues and they are the main reasons for emergency visit to a dental clinic. Management of a fracture depends on its position and the extent of root involvement. Horizontal root fractures are not seen frequently and the treatment consists of reduction and long‐term rigid fixation of the coronal segment. The present case demonstrates the successful management of two horizontally fractured maxillary central incisors with a follow‐up period of 9 months.     

Sequential bilateral germ cell tumours of the testis

Bilateral germ cell tumours of the testis are rare but a rise in their incidence is expected since with the new therapeutic possibilities a significant improvement in prognosis has been achieved even in patients with advanced metastatic spread. Of the 210 patients treated for malignent germ cell tumours at our Department, six (2.9%) developed a contralateral testicular tumour. All patients had metachronous tumours and the second tumours occurred after an interval ranging between 1 and 22 years. The epidemiology, histology, diagnosis, therapy and prognosis are discussed, and the significance of regular self-examination of the remaining testis in patients with testicular tumour is emphasized.     

Migratory, invasive and metastatic capacity of NCAM transfected rat glioma cells

A cDNA encoding a transmembrane 140 kDa isoform of the neural cell adhesion molecule, NCAM, was transfected into the rat glioma cell line BT4Cn. Transfectants with a homogeneously high expression of NCAM-B showed a decreased capacity for penetration of an artificial basement membrane when compared to cells transfected with expression-vector alone or untransfected cells. However, when injected subcutaneously into nude mice, both NCAM expressing cells and control cells produced invasive tumors. Nude mice injected with NCAM positive cells developed tumors with slower growth rates as compared to those induced by NCAM negative cells. This implies that NCAM may not only be involved in adhesive and motile behaviour of glioma cells, but also in their growth regulation.
