decrease of hyperhidrosis in the zones regulated by mental or emotional stimuli

Redistribution of perspiration as reported by the patients comprised significant reductions in palmar and axillary hyperhidrosis, and an increase in the zone of the trunk and popliteal region. The incidence of plantar anhydrosis and plantar hypohidrosis was 30.3% and 20.7%, respectively (p < 0.001). Conclusions: EBTS is followed by redistribution of body perspiration, with, and important, plantar anhydrosis and hypohidrosis. Although EBTS is the standard treatment for palmar primary hyperhidrosis, we must continue studying baseline sympathetic activity in patients affected by primary hyperhidrosis and the neuroanatomy of the sympathetic system to understand the redistribution of sweating and decrease of hyperhidrosis in the zones regulated by mental or emotional stimuli.

Recurrent sweating occurred in 17.6% of patients

The overall mean patient satisfaction rate was 78%, with a median 80% improvement on a visual analog scale from 0% (poor) to 100% (excellent). Overall, 88 patients (96.7%) developed compensatory hyperhidrosis, with the mean initial occurrence at 8.2 weeks. The symptoms of compensatory hyperhidrosis progressively worsened to the maximum degree within another 2 weeks after onset (mean 10.3 ± 1.83 weeks). In 19 patients (21.6%), symptoms of compensatory hyperhidrosis improved spontaneously within 3 months after sympathectomy (mean 13.3 weeks). Postoperative compensatory hyperhidrosis occurred in 71.4% of patients within the 1st year. Recurrent sweating occurred in only 17.6% of patients. None of these patients required repeated operation. The earliest onset of recurrent sweating was noted at 2 weeks postoperatively by three patients, and the mean initial postoperative reccurrence was 32.7 weeks after surgery.

Young woman dies after a 'routine' operation

A 'fit and healthy' young woman was left brain dead after a pioneering operation to reduce her excessive sweating went catastrophically wrong, a medical panel has heard.

Louise Field, 27, suffered severe brain damage when doctors accidentally punctured her lung and pumped gas into her stomach, the General Medical Council heard. She died two days later.

Mr Ormiston accidentally punctured her lung during the procedure, causing her oxygen levels to dip fatally. Dr Yanny allegedly failed to tackle the situation properly as the GMC hearing was told he “knew, or ought to have known” that brain damage was inevitable as he pumped Louise full of drugs to try to reverse the condition.

When the young Midland woman was rushed to another hospital, it was claimed Dr Yanny gave no indication she might have neurological problems – likely to have been caused due to a lack of oxygen.

He was also accused of failing to inform the specialist registrar at Hemel Hempstead General Hospital about drugs given, or even provide a simple anaesthetic chart.

Mr Ormiston admitted making inaccurate records after the operation and was slammed by the GMC panel for “significant departures from good medical practice”.

But he was still cleared of serious misconduct and it was decided that his fitness to practise was not impaired.

Dr Yanny managed to keep his job after offering a series of “undertakings”.

results of ETS deteriorate and compensatory sweating does not improve with time

Our findings indicate that results of ETS deteriorate and compensatory sweating does not improve with time. It is mandatory to inform patients of the potential long-term adverse effects before surgery.

hand, which may become hyperkeratotic, with fissuring and scaling

Sympathectomy for palmar hyperhidrosis is effective, but has risks associated with surgery and a permanent non-sweating hand, which may become hyperkeratotic, with fissuring and scaling.

The autonomic nervous system: an introduction to basic and clinical concepts

Post-sympathectomy neuralgia: hypotheses on peripheral and central neuronal mechanisms

Post-sympathectomy neuralgia is proposed here to be a complex neuropathic and central deafferentation/reafferentation syndrome dependent on: (a) the transection, during sympathectomy, of paraspinal somatic and visceral afferent axons within the sympathetic trunk; (b) the subsequent cell death of many of the axotomized afferent neurons, resulting in central deafferentation; and (c) the persistent sensitization of spinal nociceptive neurons by painful conditions present prior to sympathectomy. Viscerosomatic convergence, collateral sprouting of afferents, and mechanisms associated with sympathetically maintained pain are all proposed to be important to the development of the syndrome.

Sympathectomy limits blood flow to a vital organ like the brain

A reduced ability to increase cardiac output (CO) during exercise limits blood flow by vasoconstriction even in active skeletal muscle. Such a flow limitation may also take place in the brain as an increase in the transcranial Doppler determined middle cerebral artery blood velocity (MCA V(mean)) is attenuated during cycling with beta-1 adrenergic blockade and in patients with heart insufficiency. We studied whether sympathetic blockade at the level of the neck (0.1% lidocaine; 8 mL; n=8) affects the attenuated exercise - MCA V(mean following cardio-selective beta-1 adrenergic blockade (0.15 mg kg(-1) metoprolol
i.v.) during cycling. Cardiac output determined by indocyanine green dye dilution, heart rate (HR), mean arterial pressure (MAP) and MCA V(mean) were obtained during moderate intensity cycling before and after pharmacological intervention. During control cycling the right and left MCA V(mean) increased to the same extent (11.4 1.9 vs. 11.1 1.9 cm s(-1)). With the
pharmacological intervention the exercise CO (10 1 vs. 12 1 L min(-1); n=5), HR (115 4 vs. 134 4 beats min(-1)) and delta MCA V(mean) (8.7 2.2 vs. 11.4 1.9 cm s(-1) were reduced, and MAP was increased (100 5 vs. 86 2 mmHg; P < 0.05).

However, sympathetic blockade at the level of the neck eliminated the beta-1 blockade induced attenuation in delta MCA V(mean) (10.2 2.5 cm s(-1)). These results indicate that a reduced ability to increase CO during exercise limits blood flow to a vital organ like the brain and that this flow limitation is likely to be by way of the sympathetic nervous system.
