1/8. Autosomal recessive type II hereditary motor and sensory neuropathy with acrodystrophy.

    A family is described with presumed autosomal recessive inheritance in which three siblings developed a progressive neuropathy that combined limb weakness and severe distal sensory loss leading to prominent mutilating changes. Electrophysiological and nerve biopsy findings indicated an axonopathy. The disorder is therefore classifiable as type II hereditary motor and sensory neuropathy (HMSN II). The clinical features differ from those reported in previously described cases of autosomal recessive HMSN II. This disorder may therefore represent a new variant.

2/8. A new ambulatory foot pressure device for patients with sensory impairment. A system for continuous measurement of plantar pressure and a feed-back alarm.

    Abnormal and excessive plantar pressure is a major risk factor for the development of foot ulcers in patients with loss of protective pain sensation. Repeated pressure with each step can result in inflammation at specific points, followed by ulcer formation. patients with peripheral nerve disease are unable to prevent the development of such lesions, which often lead to amputation. For this reason, it has been suggested that a fundamental therapeutic intervention should be the reduction of high plantar pressure. We have developed a portable, battery-operated ambulatory foot pressure device (AFPD) which has two important functions: (1) to determine the areas of high plantar pressure, and (2) to provide an acoustic alarm, adjusted to a specific pressure load, which is triggered when weight-bearing exceeds the predetermined plantar pressure. A memory of plantar pressure parameters allows for downloading of the data and sequential analysis during the investigation period. Such an alarm device could replace the lack of pain sensation and may play an important role in the prevention of ulcer development and lower extremity amputation.

3/8. Case study to illustrate a multidisciplinary approach to a case of critical limb ischaemia and the role of chemical lumbar sympathectomy.

    This case study illustrates the role of the Podiatrist in the primary health care team and how a multidisciplinary approach to treatment promotes successful diagnosis and treatment regimes. It also outlines the role for chemical lumbar sympathectomies in treating critical lower limb ischaemia, a procedure regarded as having been superseded by more effective treatments but which proved to be the treatment of choice in this case. The subject of this case study presented at a community podiatry clinic exhibiting the signs of acute ischaemia, together with two recently developed ulcers on her right foot. After further vascular investigations, including angiograms and doppler studies, a blockage in the popliteal artery was revealed. Due to anatomically slender arteries, angioplasty and by-pass surgery were contra indicated. A chemical lumbar sympathectomy was performed in an attempt to increase blood flow to the tissues and to reduce the extreme pain being experienced by the patient. This proved successful, allowing the lesions to heal and also the collateral circulation to develop, resulting in a re-vascularized, viable foot.

4/8. Can peripheral nerve blocks contribute to heel ulcers following total knee replacement?

    Peripheral nerve blocks are widely used for postoperative analgesia following total knee replacement. We would like to present three cases of heel ulcers encountered following a peripheral nerve block for knee replacement surgery. Postoperative heel ulcers have resulted in delayed rehabilitation in all three patients. attention needs to be given to the pressure points in the foot after the nerve blocks. awareness of this uncommon complication is necessary to prevent its occurrence.

5/8. Indication, technique, and results of plantaris medialis neurovascular island flaps.

    Treatment of soft tissue defects in the heel often causes problems because of the anatomical structures of the foot and the foot's function in bearing the entire weight of the body. Various types of flap surgery have been tried, to deal with these problem areas. As ever, all the skin flaps lacked the normal quality of the plantar skin, which has fibrous septa with reduced flexibility. In view of the quality of the skin and subcutaneous tissue and the quality of the nerve supply, the technique of neurovascular island flaps for the plantaris medialis was used over the last 4 years in 14 patients, to conceal small to medium-sized heel defects. In this report, we examine anatomy, indication, technique, and results with regard to plantaris medialis island flaps. Their use is discussed in comparison with other types of flaps already used in this region.

6/8. Clinical application of posterior calf fascio-cutaneous pedicle flap in leprosy foot ulcer.

    Lower extremities of the leprosy patients are characterized by the decreased sensation of the foot from peripheral nerve damage. As a result, repetitive foot ulcers are frequently seen. When these repetitive shallow ulcers become infected, they result in deep soft tissue ulcers and even osteomyelitis. The treatment of these ulcers in leprosy is a challenging problem both to the patient himself and to medical personnel. Conventional treatment methods for these ulcers include, according to the wound condition, skin graft, local flap, long-term cast immobilization, wedge resection of the joint and even amputation in severe cases. But all these methods have the disadvantages of frequent recurrences, long hospitalization periods and permanent foot deformities. Recently in korea, despite the decreased occurrences of new patients and the decreased frequencies of facial and hand deformity formation due to the active early diagnosis and treatment, there still exists a large number of foot deformities resulting from decreased foot sensation. Moreover, treatment modalities are not definitely established. In fact, there are many environmental difficulties in applying the free flap transfer to the foot ulcer of leprosy patients in leprosy sanatorium as opposed to treating the non-leprosy patients. And so, from 1990 to 1993, we performed 6 superior-based posterior calf cross leg flap transfers and 1 distal-based flap transfer, under spinal anesthesia, referred by the leprosy sanatorium for deep foot ulcers. We obtained favorable results in 6 patients and partial necrosis in a patient who received distal based flap transfer.

7/8. The neurotropic variant of desmoplastic spindle cell melanoma of the foot--a report of two cases with special reference to its schwanian features.

    Melanomas are known to show a wide range of morphological expression. Desmoplastic Malignant melanoma (DMM) which is a variant of spindle cell melanoma, is often characterised by conspicuous growth in and around nerves which leads to a mistaken diagnosis of malignant Peripheral Nerve Sheath tumours (MPNST). We report two such cases of spindle celled DMM of the foot which displayed neurotropism. The problems and the clinical relevance of distinguishing this variant of melanoma from MPNST is discussed.

8/8. The distally based sural artery flap.

    The sural artery flap is a distally based fasciocutaneous flap. It is based on a reverse flow through anastomoses between the peroneal artery and the communicating vascular network of the medial sural nerve. In the difficult area of defects in the lower leg and the ankle and heel region, it has a wide variety of indications, even in vascularly compromised patients. It has the largest arc of rotation of all flaps that have been described in this region. The most important advantage is that it does not compromise a major artery. Furthermore, it is simple to dissect and has a low donor morbidity. A series of 15 patients is described in which we covered defects in the lower leg, malleolar, and heel regions. Seven patients were vascularly compromised seriously. Twelve flaps survived completely, two survived partially, and one flap failed.
