Primary hyperhidrosis, although lacking a precise definition and of unknown aetiology, disrupts professional and social life and may lead to emotional problems. A variety of treatment methods are used to control or reduce the profuse sweating which involves mainly the palms, soles and axillae. The simplest method, the application of topical agents, is usually attempted first for axillary and plantar sweating. Iontophoresis may provide relief especially in patients with plantar or palmar involvement. In severe cases operative intervention is necessary. Excision of sweat glands is successful in patients with axillary hyperhidrosis but the role of suction-assisted removal of axillary sweat glands remains to be determined. Sympathectomy remains the standard by which other treatments must be judged. For upper thoracic sympathectomy a variety of surgical approaches are used with satisfactory relief of hyperhidrosis. Complications related to the surgical approach, such as Horner's syndrome, brachial plexus injuries, pneumothorax and painful scars may occur, while following sympathectomy compensatory hyperhidrosis is usual and hyperhidrosis may recur. Plantar hyperhidrosis which may be exacerbated or ameliorated by upper thoracic sympathectomy and which fails to respond to non-operative intervention is relieved by lumbar sympathectomy.
Marlex (polypropylene) mesh was used to replace the abdominal wall in massive incisional herniation in 50 patients. Seventeen unsuccessful attempts at primary repair had previously been made on nine patients. Patient follow-up ranged from 6 to 120 months (mean = 45 months). There was minor hernia recurrence in four (8 per cent) patients. In each instance it was due to partial detachment of the peripheral fixation of the patch. Complications were: wound infection, four (8 per cent); wound seroma, two (4 per cent); wound haematoma, one (2 per cent); and wound sinus, six (12 per cent). Complications did not necessitate removal of the patch in any case. Inadequate peripheral attachment of the patch has been the only cause of hernia recurrence and should be avoidable.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
