An objective assessment of the sudomotor response after thoracoscopic sympathectomy

ObjectiveThoracoscopic sympathectomy has become an accepted therapeutic option for palmar hyperhidrosis. Objective assessment of sweat output after sympathectomy, however, has not been reported to date. We report for the first time sweat output measurements after sympathectomy during a 3-year postoperative period.MethodsThoracoscopic sympathectomy was performed by division of T2 and T3 sympathetic ganglia in 17 healthy adult patients with no comorbidities. Preoperative and postoperative sweat measurements were done at 29°C (below sweat threshold, at baseline, after conversation, and after a mental arithmetic challenge) and at 40°C (baseline and after exercise) with the ventilated capsule technique in left palm, sole, and chest wall. Serial postoperative measurements were conducted at 1 and 6 months and 1, 2, and 3 years.ResultsSweat output fell significantly after sympathectomy relative to preoperative levels under all experimental conditions (P < .001, analysis of variance) in the left palm. Differences in sweat outputs in the left palm were statistically significant between groups at baseline and postoperatively after mental arithmetic challenge and exercise at 40°C (P < .05, analysis of variance). Compensatory increases in the sweat outputs from the left sole and chest were observed after sympathectomy. No patients had recurrence of preoperative sweat output values at follow-up.ConclusionAccording to objective sweat output measurements, thoracoscopic sympathectomy results in long-term control of palmar hyperhidrosis. This evaluation method is valuable in investigating recurrence of symptoms or compensatory hyperhidrosis after sympathectomy, providing a robust and objective criterion for planning intervention

Factitious lymphoedema as a psychiatric condition mimicking reflex sympathetic dystrophy: a case report

<p>Abstract</p> <p>Introduction</p> <p>Reflex sympathetic dystrophy can result in severe disability with only one in five patients able to fully resume prior activities. Therefore, it is important to diagnose this condition early and begin appropriate treatment. Factitious lymphoedema can mimic reflex sympathetic dystrophy and is caused by self-inflicted tourniquets, blows to the arm or repeated skin irritation. Patients with factitious lymphoedema have an underlying psychiatric disorder but usually present to emergency or orthopaedics departments. Factitious lymphoedema can then be misdiagnosed as reflex sympathetic dystrophy. The treatment for factitious lymphoedema is dealing with the underlying psychiatric condition.</p> <p>Case presentation</p> <p>We share our experience of treating a 33-year-old man, who presented with factitious lymphoedema, initially diagnosed as reflex sympathetic dystrophy.</p> <p>Conclusion</p> <p>Awareness of this very similar differential diagnosis allows early appropriate treatment to be administered.</p

Lateral abdominal wall hernia following blunt trauma – a rare case

The presence of superficial bruising, no abnormal signs on abdominal examination and a negative FAST scan of the abdomen may not be enough to rule out intra-abdominal pathology. We report on the usefulness of CT in diagnosing a post-traumatic abdominal wall hernia

Pulmonary Embolism following Endovenous Laser Ablation (EVLA) of the Great Saphenous Vein

A 70yr old lady presented to accident and emergency with sudden onset pleuritic chest pain. A pulmonary embolus (PE) was diagnosed by CTPA. Ten days earlier she had bilateral EVLA for recurrent great saphenous vein disease. Confounding risk factors for pulmonary embolism included bilateral ligation and stripping of the great saphenous vein a year earlier, malignancy, EVLA and phlebitic tributary varices. EVLA has been shown to be an effective treatment for superficial venous insufficiency with low morbidity and high patient satisfaction. The investigation of confounding risk factors and possible causes should not compromise the initial treatment of PE
