Thoracoscopy for autonomic disorders.

Sympathetic denervation of the arm, the hand, and the heart may now be performed using minimal thoracoscopic procedures. During a 5-year period more than 500 patients were operated on with no major and only a few minor complications. An operation time of 25 minutes, a hospital stay of 1 day, and sick leave of less than 1 week have made the operation suitable for autonomous disorders such as hyperhidrosis. Other conditions such as causalgia, vascular insufficiency, and angina pectoris may be improved or disappear after sympathectomy, but the recurrence rate in Raynaud's disease is high.

Signs and symptoms of reflex sympathetic dystrophy: prospective study of 829 patients.

The pathogenesis of reflex sympathetic dystrophy--variously known as Sudeck's atrophy, causalgia, algodystrophy, and peripheral trophoneurosis--is not yet understood, and diagnosing and treating patients is difficult. We have prospectively studied 829 patients, paying particular attention to early signs and symptoms. In its early phase, reflex sympathetic dystrophy is characterised by regional inflammation, which increases after muscular exercise. Pain was present in 93% of patients, and hypoaesthesia and hyperpathy were present in 69% and 75% respectively. With time, tissue atrophy may occur as well as involuntary movements, muscle spasms, or pseudoparalysis. Tremor was found in 49% and muscular incoordination in 54% of patients. Sympathetic signs such as hyperhidrosis are infrequent and therefore have no diagnostic value. We found no evidence consistent with the presence of three consecutive phases of the disease. Early symptoms are those of an inflammatory reaction and not of a disturbance of the sympathetic nervous system. These data support the concept of an exaggerated regional inflammatory response to injury or operation in reflex sympathetic dystrophy.

Thoracoscopic cervicodorsal sympathectomy: preliminary results.

PURPOSE: The purpose of this study was to determine the feasibility, safety, and efficacy of thoracoscopic cervicodorsal sympathectomy. METHODS: From March 1990 to December 1993, we performed 21 thoracoscopic sympathectomies in 19 patients. There were 13 women and six men; age 17 to 64 years, mean 37 years. Thirteen procedures were performed on the left side and eight on the right. Indications for surgery were causalgia/reflex sympathetic dystrophy in nine patients, Raynaud's/vasculitis in six, hyperhidrosis in five, and medically refractory cardiac arrhythmia in one. RESULTS: The T1-4 sympathetic ganglia were readily identified, dissected free, and resected thoracoscopically in 19 cases, and the T3-7 ganglia were resected with thoracoscopy in one case. One case required conversion to an open thoracotomy because of dense scar from a previous first rib resection, which obscured the anatomy. Histologic confirmation of ganglia were obtained in all 21 cases. Operative duration ranged from 1.0 to 3.5 hours. Estimated blood loss was 5 to 300 cc, mean 42 cc, median 10 cc. No patient required transfusion. All 21 patients had an excellent immediate sympathectomy response. Transient Horner's syndrome developed in two patients. Postoperative residual pneumothorax (< 10%) occurred in three cases and resolved spontaneously without further treatment. In one patient pleural effusion and pneumothorax developed, which were treated with the reinsertion of the chest tube. Postoperative pain was well controlled with oral analgesics. Hospital stay was 1 to 4 days, mean 2 days, median 1 day. Follow-up at 1 to 42 months, mean 11 months, median 6 months, showed continued evidence of sympathectomy effect in all patients, except one who died of her underlying disease 1 month after operation. CONCLUSIONS: We conclude that thoracoscopic sympathectomy is feasible, safe, and effective. Further studies are indicated to confirm its long-term benefits and to determine optimal thoracoscopic techniques.

Contraindications and complications with the use of botulinum toxin.

Cosmetic use of BTX has skyrocketed in recent years, especially since the approval of BTX-A for treatment of glabellar lines. Complications and adverse reactions can easily arise, particularly for the novice injector. This paper provides insights from an experienced physician on how to avoid these complications, and how to treat them when and if they occur. The main cosmetic uses for BTX are analyzed for possible complications and adverse events. Injection techniques are discussed. Comparisons between BTX-A and BTX-B are given to point out the need for different injection techniques based on the product being used. Treatment recommendations for the Glabella, Brow, Crow's Feet, Upper Lip Wrinkling/Lines, Depressor Anguli Oris, Nasolabial Folds, Mentalis, Neck and Hyperhidrosis are discussed, as well as systemic complications. It is important for the injecting physician to be familiar with these potential complications, even though the use of BTX has been safe and generally well tolerated, because it will lead to even greater success with the use of BTX.

Anatomical variations of rami communicantes in the upper thoracic sympathetic trunk.

OBJECTIVE: The aim of this study was to clearly delineate the anatomical variations of the communicating rami in the upper thoracic sympathetic nervous system and to help develop better surgical method for essential palmar hyperhidrosis. METHODS: Anatomical dissections of the upper thoracic sympathetic chains with sympathetic ganglia and communicating rami have been carried out in 42 adult Korean cadavers (male 26, female 16). The rami communicantes were classified into three types (Normal: transverse or oblique rami connected to the intercostal nerve of the same level; AR: ascending rami connected to the higher level; DR: descending rami to the lower level) based on the anatomical relationship of the thoracic sympathetic ganglia to the intercostal nerves. Both sides of the upper thoracic sympathetic nervous system were compared in the same individual. The number of the communicating rami was recorded in 32 cadavers (64 sides). The distance from the rami communicantes to the sympathetic trunk was measured in 26 cadavers (52 sides). RESULTS: The incidence of AR (ascending rami) and DR (descending rami) arising from the second sympathetic ganglion was 53.6% (45/84), 46.4% (39/84). From the third thoracic sympathetic ganglion, the incidence of AR was 5.9% (5/84) and that of DR was 26.2% (22/84). And in the fourth thoracic sympathetic ganglion, the incidence of AR was 4.8% (4/84) and DR was 8.3% (7/84), respectively. When we compared anatomical structures of both sides among the 42 cadavers dissected, only 14.3% (6/42) had similar anatomy of the rami communicantes bilaterally. Among 32 cadavers (64 sides), the mean number of rami communicantes at the second thoracic sympathetic ganglion was 2.1/2.5 in the left and the right side. At the third and the fourth thoracic sympathetic ganglion, the mean number was 1.9/1.6 and 1.7/1.7 in each side. The mean distance from the thoracic sympathetic chain to the most distal communicating rami of the left and right side at the second intercostal nerve was 7.81/9.40 mm among 26 cadavers. The mean distance of each side was 6.81/7.94 mm at the level of the third intercostal nerve. And at the level of the fourth intercostal nerve, the mean distance was 7.48/10.92 mm, respectively. CONCLUSION: On the basis of this study, the anatomical variations of communicating rami could explain some surgical failures and recurrences. Moreover, in addition to the conventional surgical methods (sympathectomy, sympathicotomy, clipping of sympathetic chain and ramicotomy), dividing the inconstant sympathetic pathways (nerve of Kuntz, ascending or descending rami communicantes) on the second, the third and the fourth ribs will help to get better surgical effect.

Upper dorsal endoscopic thoracic sympathectomy: a comparison of one- and two-port ablation techniques.

OBJECTIVE: Facial blushing and hyperhidrosis, particularly in the facial, axillary or palmar distribution, are socially, professionally, and psychologically debilitating conditions. Endoscopic thoracic sympathectomy can be carried out through multiple ports or by using a single port and a modified thoracoscope with integrated electrocautery. We reviewed our own experience to compare outcomes between these methods. METHODS: One hundred and nine consecutive endoscopic thoracic sympathectomies performed on 96 patients (M:F, 30:66) were examined with respect to operative method, symptom control, and patient satisfaction. Complete follow-up was available on 144 treated sides in 77 patients (80.2%), 38 treated with two ports, 39 performed by a one-port procedure. Mean age was 32.6 years (range 18-63) with a median follow-up of 25 months (range 5-85). Pooled data showed that the mean duration hospital stay was 1.6 nights with no deaths, conversions, or neurological injuries. RESULTS: The one-port group showed superior outcomes in terms of hospital stay, rate of postoperative pneumothorax, and the need for chest drain insertion; however, there was no correlation between number of ports and patient satisfaction. The mean overall satisfaction rating out of 5 was 3.3 with 76.6% of patients rating the outcome as 3 or more. 90.9% had an initial improvement in symptoms, although 21 patients (27.3%) described a late return of symptoms. CONCLUSION: Endoscopic thoracic sympathectomy can be safely and effectively carried out using a single port with similar results to the traditional two-port procedure. The one-port procedure may allow for a shorter duration of stay and lower complication rate.

Pre-emptive local anesthesia for needlescopic video-assisted thoracic surgery: a randomized controlled trial.

OBJECTIVE: Studies in other surgical specialties have suggested that pre-emptive wound infiltration using a local anesthetic may reduce post-operative pain. We report the first randomized trial to assess the use of pre-emptive local anesthesia in video-assisted thoracic surgery (VATS). METHOD: Thirty-one consecutive patients undergoing bilateral needlescopic VATS sympathectomy for palmar hyperhidrosis were studied prospectively. Each patient acted as their own control. For each patient, one side was randomized to receive 10ml 0.5% bupivicaine injected to the port sites before incision, and the contralateral control side to receive 10ml saline. Pain severity on a visual analog scale (VAS) was recorded for each chest side at 4h, 1 day and 7 days following surgery. All patients were blinded to the results of randomization throughout the study. RESULTS: Follow up was complete for all patients. At 7 days after surgery, wound pain was significantly reduced by pre-emptive local anesthesia, with 10 (62.5%) of the 16 patients having residual pain reporting less pain on the pre-treated side (p=0.039). There was a trend for reduced pain on the pre-treated side at the other time points. Pain reduction by pre-emptive local anesthesia was not correlated with any demographic or clinical variable. Chest wall paresthesia distinct from localized wound pain was noted by six patients (19.4%), but was not reduced by pre-emptive local anesthesia. Overall, the post-operative discomforts felt by the patients after needlescopic VATS were mild, and did not cause significant functional disturbances. CONCLUSION: Pre-emptive wound infiltration with a local anesthetic may reduce post-operative wound pain in needlescopic VATS procedures.

Expanding use of botulinum toxin.

Botulinum toxin type A (BTX-A) is best known to neurologists as a treatment for neuromuscular conditions such as dystonias and spasticity and has recently been publicized for the management of facial wrinkles. The property that makes botulinum toxin type A useful for these various conditions is the inhibition of acetylcholine release at the neuromuscular junction. Although botulinum toxin types A and B (BTX-A and BTX-B) continue to find new uses in neuromuscular conditions involving the somatic nervous system, it has also been recognized that the effects of these medications are not confined to cholinergic neurons at the neuromuscular junction. Acceptors for BTX-A and BTX-B are also found on autonomic nerve terminals, where they inhibit acetylcholine release at glands and smooth muscle. This observation led to trials of botulinum neurotoxins in various conditions involving autonomic innervation. The article reviews the emerging use of botulinum neurotoxins in these and selected other conditions, including sialorrhea, primary focal hyperhidrosis, pathological pain and primary headache disorders that may be of interest to neurologists and related specialists.

Long-term pulmonary function after thoracic sympathectomy.

BACKGROUND: The purpose of this study was to evaluate the long-term and midterm effects of thoracic sympathectomy on pulmonary function and to assess the influence of the sympathetic nervous system on bronchomotor tone. METHODS: Thirty-seven consecutive patients were diagnosed with primary hyperhidrosis requiring thoracic sympathectomy and were included in this study. Spirometry and methacholine challenge testing were performed before and 3 months after surgery. To assess the long-term effects of the intervention, another spirometric study was performed 1 year later. RESULTS: Spirometry 3 months after surgery showed a significant decrease in the forced vital capacity (-5.2%), the forced expiratory volume in the first second (-6.1%), and the forced expiratory flow between 25% and 75% of vital capacity (-5.1%). Whereas methacholine challenge testing before surgery was positive in 3 subjects (2 of whom were asthmatic), it was positive in 6 patients after the procedure; differences were not statistically significant. After 12 months, forced vital capacity started recovering, and forced expiratory volume in the first second and forced expiratory flow rate 25% to 75% showed a sustained and significant reduction (-2.8% and -11.2%, respectively); however, patients remained asymptomatic. CONCLUSIONS: We conclude that thoracic sympathectomy generates a mild, although significant, impairment of the bronchomotor tone, with no clinical consequences. These results suggest that the sympathetic nervous system is involved in pulmonary bronchomotor tone.

Influence of sympathectomy in humans on the rhythmicity of 6-sulphatoxymelatonin urinary excretion.

The amount of 6-sulphatoxymelatonin, the chief metabolite of melatonin, in the urine was measured in nine patients, who were subjected to bilateral sympathectomy at the second thoracic ganglionic level for treatment of hyperhidrosis of the palms. All patients showed before surgery a normal 6-sulphatoxymelatonin excretion with a peak in the excretion during the night time. After the sympathectomy, the high night time excretion was clearly abolished in five patients but remained high in four patients. This indicates that the segmental locations of the preganglionic sympathetic perikarya in the spinal cord, stimulating the melatonin secretion in the pineal gland in humans, vary between individuals. An increase in daytime melatonin excretion was observed in the patients responding to the sympathectomy with an abolished 6-sulphatoxymelatonin rhythm. This increase could indicate that the final sympathetic neurons innervating the pineal gland might have a both stimulatory and inhibitory function.

The efficacy of intraoperative internal intercostal nerve block during video-assisted thoracic surgery on postoperative pain.

BACKGROUND: Video-assisted thoracic surgery (VATS) is widely used for many thoracic surgical procedures. Post-operative pain is less after VATS than after conventional thoracic surgery, but is still significant. The objective of this study was to assess the efficacy of thoracoscopic, internal intercostal nerve block in alleviating immediate postoperative pain. METHODS: Thirty-two patients underwent VATS bilateral sympathectomy for the treatment of hyperhidrosis. The patients were randomly divided into two groups with similar demographic and preoperative physiologic parameters. Group A (n = 16) was submitted to thoracoscopic, internal intercostal nerve blocks performed at T2, T3, and T4 intercostal levels using 3 cc of 0.5% bupivacain in each intercostal space. The injections were performed bilaterally, immediately after the sympathectomy, through the same port. Group B (n = 16) underwent bilateral thoracic sympathectomy without the block. During the immediate postoperative period, heart rate, blood pressure, respiratory rate, pain score, and analgesic requirements were monitored every 30 minutes. RESULTS: No morbidity was recorded in association with the thoracoscopic, internal intercostal nerve block. The mean heart rates (77 +/- 6 vs 89 +/- 12 beats per minute, p < 0.001), respiratory rates (15 +/- 2 vs 18 +/- 3 respirations per minute, p < 0.01), pain score (1.9 +/- 0.6 vs 2.7 +/- 0.5, p < 0.01), and postoperative analgesic requirements (20 +/- 18 vs 50 +/- 21 mg pethidine HCL, p < 0.001) were significantly lower in group A. There was no significant difference in blood pressures. CONCLUSIONS: Thoracoscopic, internal intercostal nerve block with bupivacain 0.5% during VATS is safe and effectively reduced the immediate postoperative pain and analgesic requirements.

[Botulism toxin in practice].

Botulinum toxins (A and B) are neurotoxins derived from Clostridium botulinum. Clostridium are anaerobic bacteria. C. botulinum produces exotoxins (A to G) with distinct antigenicities. The neurotoxins inhibit the release of the neurotransmitter acetylcholine from the axon terminals of motor neurons. Botulinum toxin is officially used in clinic for the treatment of muscular hyperactivity (strabismus, blepharospam, cervical dystonia). Botulinum toxins are also used in non recognized clinical applications: neurogenic incontinence, palmar and axillary hyperhidrosis, chronic anal fissure. The respective formulations of Botox, Dysport and Neurobloc are described. Special considerations for administration are introduced.

Iontophoresis in dermatology. A review.

Iontophoresis, the process of increasing the penetration of drugs into surface tissues by the application of an electric current, has been applied to a great many disease conditions over its 200-year history. Although its greatest success has been in the treatment of hyperhidrosis, it is steadily finding new applications. Many aspects of the mechanisms of iontophoresis have yet to be studied before the technic is both fully understood and maximally utilized. In this article we review the literature on iontophoresis as it pertains to dermatology, including the basic principles, engineering aspects.

Biology of sweat glands and their disorders. II. Disorders of sweat gland function.

Part I of this article (J Am Acad Dermatol 1989; 20:537-63) focused on normal sweat gland function. Part II provides a discussion of hyperhidrosis and hypohidrosis. Hyperhidrotic disorders affect the palms and soles and the axillae and are associated with previous spinal cord injuries, peripheral neuropathies, brain lesions, intrathoracic neoplasms, systemic illness, and gustatory sweating. Hypohidrotic disorders include anhidrotic ectodermal dysplasia, hereditary sensory neuropathy, Holmes-Adie syndrome, and generalized anhidrosis.

Nonneoplastic disorders of the eccrine glands.

Eccrine glands are uniquely susceptible to a variety of pathologic processes. Alteration in the rate of sweat secretion manifests as hypohidrosis and hyperhidrosis. Obstruction of the eccrine duct leads to miliaria. The excretion of drugs into eccrine sweat may be a contributory factor in neutrophilic eccrine hidradenitis (NEH), syringosquamous metaplasia (SSM), coma bulla, and erythema multiforme (EM). Alterations in the electrolyte composition of eccrine sweat can be observed in several systemic diseases, most notably cystic fibrosis. This article summarizes current knowledge of eccrine gland pathophysiology.

Agenesis of the corpus callosum associated with paroxysmal hypothermia: Shapiro's syndrome.

Spontaneous recurrent hypothermia and hyperhidrosis associated with agenesis of the corpus callosum was first described by Shapiro and Plum in 1967. Since then, several cases with similar symptoms (now known as Shapiro's syndrome or spontaneous periodic hypothermia) have been described. We report another case of this syndrome in a 21-year-old-man, and discuss possible pathogenetic mechanisms and therapeutic approaches.
