Major amputation for intractable extremity melanoma after failure of isolated limb perfusion.

AIM: The aim of this study was to analyse indications and results of amputation for intractable extremity melanoma after failure of isolated limb perfusion (ILP). METHODS: Between 1978 and 2001, 451 patients with loco-regional advanced extremity melanoma underwent 505 ILPs. Amputation of the affected extremity had to be carried out for intractable recurrent disease in 11 of these patients. RESULTS: The indications for amputation were uncontrollable pain (n=2), extensive loco-regional tumour progression (n=4), loss of ankle function due to local tumour growth (n=1), and ulcerating and fungating lesions, not responding to other treatments (n=4). Four patients developed stump recurrence after amputation. Ten patients died of melanoma metastases after a median of 11 months (range 2-110 months). Two patients survived more than 5 years after amputation. CONCLUSIONS: Major amputation is rarely indicated for intractable extremity melanoma but long-term survival can be achieved in selected patients.     

Disseminating adamantinoma of the tibia

Patient. This report describes a patient with a primary long bone adamantinoma. The lesion was initially wrongly diagnosed as fibrous dysplasia and the patient was treated by curettage. At second local recurrence, the tumour had progressed from an osteofibrous dysplasia-like to a full-blown classic adamantinoma, with metastatic potential to the lungs 19 years after the initial treatment. Lung metastasectomy by sternotomy was carried out twice in a period of over 3.5 years. The patient is currently alive without evidence of other metastatic disease.Discussion. From the files of the Netherlands Committee on Bone Tumors, another five patients with lung metastaseswere studied. All types of adamantinoma should be treated by complete en bloc resection. For patients with metastatic spread to the lungs, close radiological follow-up and excision of tumour nodules seems to be the only logic treatment modality.     

Humeral blade plate fixation of intercalary allografts and segmentally comminuted proximal humeral fractures: a preliminary report

The AO 90° humeral blade plate is a relatively new device, whose primary indication and previously described use is for proximal humeral fracture non-union. This study describes the use of the humeral blade plate for extended indications-fixation of segmentally comminuted proximal humeral fractures in two patients and fixation of humeral intercalary allografts after primary humeral neoplasm resection in three patients. A mean follow-up of 20 months revealed union in both fractures and five of the six allograft-host junctions. One patient required subsequent bone grafting for non-union at a proximal allograft-host junction. Functional results were excellent in three patients, good in one, and fair in one. Problems encountered intraoperatively were directly related to the limited array of implants. The long plates which were needed had blades which were too long and required intra-operative trimming in three cases. In four cases, additional plates were used to supplement the blade plate for distal fixation. In conclusion, the humeral blade plate is a useful device for fixation in these extended indications, but longer plates with 30.0 and 40.0-mm blade lengths should be made available.     

High relapse-free survival after preoperative and intraoperative radiotherapy and resection for sulcus superior tumors

STUDY OBJECTIVES: Relapse-free survival in patients with sulcus superior tumors. DESIGN: Prospective registration study. SETTING: Department of surgical oncology of a university hospital. PATIENTS: Twenty-one patients treated with preoperative radiotherapy (46 Gy), lobectomy and chest-wall resection, and intraoperative radiotherapy (10 Gy). RESULTS: After a median follow-up of 18 months, 18 patients (85%) were free from locoregional relapse, while 8 patients were still alive. CONCLUSIONS: The results show that this protocol can achieve excellent local tumor control and can even be used for palliative treatment.     

Cutaneous clues for diagnosing X‐chromosomal disorders

In a multidisciplinary outpatient clinic for hereditary skin diseases and/or syndromes involving the skin, 7% (30 of 409) of patients were found to have an abnormality involving the X chromosome, a mutation in a gene located on the X chromosome or a clinical diagnosis of an X‐linked monogenetic condition. The collaboration of a dermatologist and a clinical geneticist proves to be very valuable in recognizing and diagnosing these conditions. By combining their specific expertize in counselling an individual patient, X‐linked diagnoses were recognized and could be confirmed by molecular and/or cytogenetic studies in 24 of 30 cases. Mosaicism plays an important role in many X‐linked hereditary skin disorders. From our experience, we extracted clinical clues for specialists working in the field of genetics and/or dermatology for considering X‐linked disorders involving the skin.     

Progressively increasing fracture risk with advancing age after initial incident fragility fracture: The Tromsø Study

The risk of subsequent fracture is increased after initial fractures; however, proper understanding of its magnitude is lacking. This population‐based study examines the subsequent fracture risk in women and men by age and type of initial incident fracture. All incident nonvertebral fractures between 1994 and 2009 were registered in 27,158 participants in the Tromsø Study, Norway. The analysis included 3108 subjects with an initial incident fracture after the age of 49 years. Subsequent fracture (n = 664) risk was expressed as rate ratios (RR) and absolute proportions irrespective of death. The rates of both initial and subsequent fractures increased with age, the latter with the steepest curve. Compared with initial incident fracture rate of 30.8 per 1000 in women and 12.9 per 1000 in men, the overall age‐adjusted RR of subsequent fracture was 1.3 (95% CI, 1.2–1.5) in women, and 2.0 (95% CI, 1.6–2.4) in men. Although the RRs decreased with age, the absolute proportions of those with initial fracture who suffered a subsequent fracture increased with age; from 9% to 30% in women and from 10% to 26% in men, between the age groups 50–59 to 80+ years. The type of subsequent fracture varied by age from mostly minor fractures in the youngest to hip or other major fractures in the oldest age groups, irrespective of type and severity of initial fracture. In women and men, 45% and 38% of the subsequent hip or other major fractures, respectively, were preceded by initial minor fractures. The risk of subsequent fracture is high in all age groups. At older age, severe subsequent fracture types follow both clinically severe and minor initial incident fractures. Any fragility fracture in the elderly reflects the need for specific osteoporosis management to reduce further fracture risk. © 2013 American Society for Bone and Mineral Research.
