Long-Term Efficacy of Subcutaneous Sweat Gland Suction Curettage for Axillary Hyperhidrosis: A Prospective Gravimetrically Controlled Study

DERMATOLOGIC SURGERY, Issue 9 2008
STEPHANIE DARABANEANU PHD
BACKGROUND Subcutaneous sweat gland suction curettage (SSGSC) is gaining acceptance as a therapy for axillary hyperhidrosis. Despite its acceptance, there remains a lack of prospective data describing the efficacy and long-term outcome of SSGSC. OBJECTIVE We examined the sweat rates and patients' satisfaction of 12 months following SGSC in 28 patients with axillary hyperhidrosis. METHODS Axillary sweat rates were determined by semiquantitative gravimetry. A questionnaire was used to determine patients' satisfaction. RESULTS A 58% reduction in sweat rate under resting conditions and an 85% reduction during aerobic exercise in sweat rates was observed. A subdivision of patients into three groups based on their baseline preoperative sweat rates (<25, 25,50, and >50 mg/min) showed that patients with resting sweat rates over 25 mg/min benefited particularly from this procedure, whereas patients with less than 25 mg/min did not. CONCLUSION SSGSC produces a significant reduction in the preoperative sweat rates. A low complication rate and a high degree of patient satisfaction were observed. Long-term follow-up evaluations demonstrate a low number of relapses, making SSGSC a convenient and satisfactory method of treating axillary hyperhidrosis. It should be considered in patients refractory to conventional therapies with baseline sweat rates greater than 25 mg/min. [source]

Histological and Clinical Findings in Different Surgical Strategies for Focal Axillary Hyperhidrosis

DERMATOLOGIC SURGERY, Issue 8 2008
FALK G. BECHARA MD
INTRODUCTION Although a variety of different surgical strategies for focal axillary hyperhidrosis (FAH) have proven effective, little is known of intraoperative and postoperative histologies of different surgical methods. OBJECTIVE The objective was to use pre-, intra-, and postoperative histologic findings to evaluate different surgical procedures for FAH in establishing a possible correlation between the interventions and clinical outcome. MATERIAL AND METHODS A total of 40 patients underwent surgery with 15 undergoing liposuction-curettage (LC), 14 radical skin excision (RSE) with Y-plasty closure, and 11 a skin-sparing technique (SST). Before surgery, density and ratio of eccrine and apocrine sweat glands were evaluated with routine histology. Further biopsies were taken directly after surgery in the RSE and SST groups and 1 year postoperatively in all patients. Additionally, gravimetry was performed, side effects were documented, and patients were asked to evaluate the aesthetic outcome of the surgical method by using an analogue scale. RESULTS Preoperatively, the mean density of eccrine glands was 11.1/cm2 compared to 16.9/cm2 apocrine glands (apocrine/eccrine ratio, 1.6). Biopsy specimen directly after surgery showed remaining sweat glands in 7/15 (46.7%) LC patients and in 4/11 (36.4%) of the SST patients. One year after surgery, sweat gland density was significantly reduced in the LC (79.1%) and the SST (74.9%) groups. In the RSE group, only scar formation was present. Gravimetry showed significantly reduced sweat rates 12 months after surgery in all groups (LC, 66.4%; SST, 62.9%; RSE, 65.3% [p<.05]). Most frequent side effects were hematoma (LC, n=3; SST, n=2; RSE, n=3), subcutaneous fibrotic bridles (LC, n=8; SST, n=3; RSE, n=0), skin erosion (LC, n=3; SST, n=4; RSE, n=0), focal hair loss (LC, n=9; SST, n=11; RSE, n=14), and paresthesia (LC, n=4; SST, n=3; RSE, n=5). CONCLUSION Histologic distribution and density of sweat glands were comparable to previous studies. All three surgical procedures evaluated are effective in the treatment of FAH. RSE and SST techniques are associated with a higher risk of side effects and cause more extensive scarring. However, one LC patient (n=1; 6.7%) did not respond to treatment. [source]

Ice Minimizes Discomfort Associated with Injection of Botulinum Toxin Type A for the Treatment of Palmar and Plantar Hyperhidrosis

DERMATOLOGIC SURGERY, Issue 2007
KEVIN C. SMITH MD
BACKGROUND The value of botulinum toxin type A (BTX-A) for treatment of palmar and plantar hyperhidrosis (HH) has been limited by injection pain, which in the past has generally required administration of a nerve block. We describe the successful use of ice applied to the intended injection point followed immediately by application of either ice or vibration to skin adjacent to the injection point to reduce discomfort associated with injection of BTX-A for the treatment of palmar and plantar HH. RESULTS During needle insertion and injection of BTX-A, both the application of ice to the intended injection point followed by application of ice adjacent to the injection point (ice+ice) and the application of ice to the intended injection point followed by application of vibration adjacent to the injection point have been preferred by our patients to nerve block. These two techniques allow efficient treatment of both hands and/or both feet in a single session. CONCLUSION By eliminating the need for nerve blocks, the techniques described here will enlarge the pool of physicians who can administer BTX-A for palmar and plantar HH, and will enlarge the pool of patients who are willing to have this treatment.

Double-Blind, Randomized, Placebo-Controlled Pilot Study of the Safety and Efficacy of Myobloc (Botulinum Toxin Type B) for the Treatment of Palmar Hyperhidrosis

DERMATOLOGIC SURGERY, Issue 3 2005
Leslie Baumann MD
Background Palmar hyperhidrosis is a problem of unknown etiology that affects patients both socially and professionally. Botulinum toxin type B (Myobloc), approved by the Food and Drug Administration for use in the treatment of cervical dystonia in the United States in December 2000, has subsequently been used effectively in an off-label indication to treat hyperhidrosis. There are sparse data, however, in the literature evaluating the safety and efficacy of BTX-B for the treatment of palmar hyperhidrosis. Objective We evaluated the safety and efficacy of Myobloc in the treatment of bilateral palmar hyperhidrosis. This was a double-blind, randomized, placebo-controlled study to report on the safety and efficacy of Myobloc. Methods Twenty participants (10 men, 10 women) diagnosed with palmar hyperhidrosis were injected with either Myobloc (5,000 U per palm) or a 1.0 mL vehicle (100 mM NaCl, 10 mM succinate, and 0.5 mg/mL human albumin) into bilateral palms (15 Myobloc, 5 placebo). The participants were followed until sweating returned to baseline levels. The main outcome measures were safety, efficacy versus placebo, and duration of effect. Results A significant difference was found in treatment response at day 30, as determined by participant assessments, between 15 participants injected with Myobloc and 3 participants injected with placebo. The duration of action, calculated in the 17 participants who received Myobloc injections and completed the study, ranged from 2.3 to 4.9 months, with a mean duration of 3.8 months. The single most reported adverse event was dry mouth or throat, which was reported by 18 of 20 participants. The adverse event profile also included indigestion or heartburn (60%), excessively dry hands (60%), muscle weakness (60%), and decreased grip strength (50%). Conclusion Myobloc proved to be efficacious for the treatment of palmar hyperhidrosis. Myobloc had a rapid onset, with most participants responding within 1 week. The duration of action ranged from 2.3 to 4.9 months, with a mean of 3.8 months. The adverse event profile included dry mouth, indigestion or heartburn, excessively dry hands, muscle weakness, and decreased grip strength. MYOBLOC WAS PROVIDED FOR THIS STUDY BY ELAN PHARMACEUTICALS. [source]

Plantar Hyperhidrosis and Pitted Keratolysis Treated with Botulinum Toxin Injection

DERMATOLOGIC SURGERY, Issue 12p2 2004
Bhertha M. Tamura
Background. Sulcate plantare keratolysis or pitted keratolysis (plantar keratolysis sulcatum) is a disease that is commonly found in tropical countries. Patients have also reported plantar hyperhidrosis. Objective. Two patients with pitted keratolysis resistant to topical and systemic treatments are described. Methods. Both patients were injected with botulinum toxin distributed evenly through the plantar extension. Results. The response to the treatment was excellent despite using a low dose of botulinum toxin with the plantar keratolysis healing completely. Conclusion. Hyperhidrosis may be considered the major etiologic factor for pitted keratolysis that does not respond to treatment. [source]

Improving Botulinum Toxin Therapy for Palmar Hyperhidrosis: Wrist Block and Technical Considerations

DERMATOLOGIC SURGERY, Issue 1 2001
Ada Regina Trindade De Almeida MD
Botulinum A exotoxin has become an excellent therapeutic option to treat focal hyperhidrosis, but when the problem affects the palmar region the technique has some drawbacks. Pain with injection is difficult to tolerate and the large dose needed to treat both hands are two concerns, as well as muscle weakness secondary to botulinum toxin diffusion and the possibility of antibody production. All these problems limit the number of patients treated. The author's suggestion is to treat only the dominant hand, after performing a wrist block. The use of a device adapted from a cartridge rubber may help to control the injection depth and the risk of muscular weakness. [source]

Palmar Hyperhidrosis: Long-term Follow-up of Nine Children and Adolescents Treated with Botulinum Toxin Type A

PEDIATRIC DERMATOLOGY, Issue 4 2009
Lúcia H. Coutinho dos Santos M.D., Ph.D.
Nine patients with palmar hyperhidrosis underwent treatment with botulinum A. Before the session, and in the 1-, 3-, 6-, 9-, and 12-month post-session follow-ups, the patients were administered the Minor test, gravimetry, the Scales of Frequency and Severity, and the Questionnaire of Quality of Life. The mean age was 11 years, with seven girls and two boys. Each patient was administered at least one treatment of botulinum toxin in the palm of the hands (75,150 U for palm), with the mean number of sessions 2.2 (range: 1,4). All sessions in the patients resulted in drying of the hands, with a mean duration of effect of 7 months. Botulinum toxin A controls excessive sweat in the palms of children and adolescents who have primary palmar hyperhidrosis, with an improvement in the quality of life. The therapy is safe and effective in this pediatric group and can be considered before surgical interventions. [source]

Spinal Dysraphism Presenting as Acro-Osteolysis: Report of Four Cases

PEDIATRIC DERMATOLOGY, Issue 2 2001
Gomathy Sethuraman M.D.
The disorder may occur as familial, idiopathic, or secondary to vascular, inflammatory, or neurologic conditions. Acro-osteolysis is rare in association with spinal dysraphism. It is even rarer for it to be the presenting symptom in spinal dysraphism. We report here four patients in whom the diagnosis of spinal dysraphism was established while investigating for the various causes of acro-osteolysis. All four patients presented with trophic changes and acro-osteolysis. Hyperhidrosis in the affected limb was seen in three patients. One patient had leg pain, the others had no sensory or motor deficits. Magnetic resonance imaging showed spinal dysraphism in all four patients. [source]

Heart Rate Variability in Patients with Essential Hyperhidrosis: Dynamic Influence of Sympathetic and Parasympathetic Maneuvers

ANNALS OF NONINVASIVE ELECTROCARDIOLOGY, Issue 1 2005
Dayimi Kaya M.D.
Background: Essential hyperhidrosis has been associated with an increased activity of the sympathetic system. In this study, we investigated cardiac autonomic function in patients with essential hyperhidrosis and healthy controls by time and frequency domain analysis of heart rate variability (HRV). Method: In this study, 12 subjects with essential hyperhidrosis and 20 healthy subjects were included. Time and frequency domain parameters of HRV were obtained from all of the participants after a 15-minute resting period in supine position, during controlled respiration (CR) and handgrip exercise (HGE) in sitting position over 5-minute periods in each stage. Results: Baseline values of HRV parameters including RR interval, SDNN and root mean square of successive R-R interval differences, low frequency (LF), high frequency (HF), normalized unit of high frequency (HFnu), normalized unit of low frequency (LFnu), and LF/HF ratio were identical in two groups. During CR, no difference was detected between the two groups with respect to HRV parameters. However, the expected increase in mean heart rate (mean R-R interval) did not occur in hyperhidrotic group, whereas it did occur in the control group (Friedman's P = 0.000). Handgrip exercise induced significant decrease in mean R-R interval in both groups and no difference was detected between the two groups with respect to the other HRV parameters. When repeated measurements were compared with two-way ANOVA, there was statistically significant difference only regarding mean heart rate in two groups (F = 6.5; P = 0.01). Conclusion: Our overall findings suggest that essential hyperhidrosis is a complex autonomic dysfunction rather than sympathetic overactivity, and parasympathetic system seems to be involved in pathogenesis of this disorder.

Routine use of Xeomin® in patients previously treated with Botox®: long term results

EUROPEAN JOURNAL OF NEUROLOGY, Issue 2009
D. Dressler
Background and purpose:, Based upon large and carefully performed studies Xeomin® was first registered in 2005. However, its real potential can only be assessed, when it is used outside of study design restrictions, in an independent setting, in off-label indications and during continued use. Methods and results:, Two hundred and sixty-three patients (91 with dystonia, 84 with spasticity, 17 with hemifacial spasm and re-innervation synkinesias, 64 with hyperhidrosis, 7 with hypersalivation), who were previously treated with Botox® for at least 1 year under stable conditions, were converted in a blinded fashion to Xeomin® using a 1:1 conversion ratio and identical treatment parameters. Therapeutic outcome and adverse effects were monitored by neurological examination and structuralised interviews. In 223 patients (all except those with axillary hyperhidrosis) Xeomin® was used continuously throughout a 3 year period. Altogether 1050 injection series were performed. Patients with dystonia received 261.5 ± 141.0 MU Botox®/Xeomin®, patients with spasticity 450.5 ± 177.1 MU, patients with hemifacial spasm and reinnervation synkinesias 44.7 ± 19.5 MU and patients with hyperhidrosis 286.9 ± 141.6 MU. The maximum botulinum toxin dose applied was 840 MU. There were no subjective or objective differences between Botox® and Xeomin® treatments with respect to onset latency, maximum and duration of their therapeutic effects and their adverse effect profiles. Long-term use did not reveal additional safety relevant aspects. None of the patients lost therapeutic efficacy during the observation period. Conclusions:, Xeomin® can be used safely in doses of up to 840 MU. Even when applied in high doses it did not produce secondary therapy failure. There were no diffusion differences between Botox® and Xeomin®. Using a conversion ratio of 1:1 Xeomin® and Botox® can easily be exchanged in a continued treatment. [source]

Nodular vasculitis in systemic lupus erythematosus

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2008
Annet Westers-Attema MD
A 42-year-old man presented with fever, photosensitivity, headaches, myalgia, hyperhidrosis, muscle weakness, alopecia, nasal crustae, weight loss, painful nails, arthritis, oral ulcers, erythema, discoid cutaneous lesions, and painful subcutaneous nodes. We made a diagnosis of systemic lupus erythematosus (SLE), type II cryoglobulinemia, and nodular vasculitis. In the skin, different types of vasculitis may be observed. Typically, histology shows leukocytoclastic vasculitis of superficial vessels both in SLE and mixed cryoglobulinemia, which clinically results in palpable purpura. In our patient, however, histopathological examination of the subcutaneous nodes not only revealed leukocytoclastic vasculitis of the superficial vasculature but also showed even more extensive involvement of dermal and subdermal small and medium sized vessels, giving rise to a nodular vasculitis.

Quantitative effect of anodal current in the treatment of primary hyperhidrosis by direct electrical current

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 7 2006
rul H. Aydemir MD
Aim, To determine the quantitative effect and technique of use of the anodal current for the treatment of palmoplantar hyperhidrosis on local areas of the palms and soles. Methods, Twelve patients (four males and eight females) with idiopathic palmoplantar hyperhidrosis were enrolled in this study. Having determined the initial sweat intensities of both hands using the pad glove method, direct electrical current (d.c.) treatment was applied to the palms of the patients using a complete regulated d.c. unit for which the current and potential ranges were 0,30 mA and 0,90 V, respectively. Electrodes were placed into two separate water plates, and covered with pad made from gauze and cotton material. The pads were moisturized with tap water for current conduction. The anodal current was applied to the right hands of six patients (group I) and to the left hands of the remainder (group II). After seven treatments had been completed for the palms, the final sweat intensities of the hands were measured. Results, In both groups, the final sweat intensities of the hands subjected to the anodal current were significantly decreased in comparison with the initial values, regardless of whether the anodal current was applied to the right or left hand (P < 0.05). In contrast, the final sweat intensities of the other hands subjected to the cathodal current were not significantly decreased (P > 0.05). Conclusions, It can be concluded that the anodal current is more effective in reducing sweating on the palms when applied either to the right or left hand. In the treatment of palmoplantar or localized hyperhidrosis, the anodal current should be referenced first to treat the sweatier hand or foot, or a local hyperhidrotic area of the skin. The selection of the anodal current for one hand for the first five or seven sessions appears to be more effective than the use of polarity changes for each session. [source]

Sleep problems and daytime somnolence in a German population-based sample of snoring school-aged children

JOURNAL OF SLEEP RESEARCH, Issue 1 2007
STEFFEN EITNER
Summary Habitual snoring is associated with daytime symptoms like tiredness and behavioral problems. Its association with sleep problems is unclear. We aimed to assess associations between habitual snoring and sleep problems in primary school children. The design was a population-based cross-sectional study with a nested cohort study. The setting was twenty-seven primary schools in the city of Hannover, Germany. Habitual snoring and sleep problems were assessed in primary school children using an extended version of Gozal's sleep-disordered breathing questionnaire (n = 1144). Approximately 1 year later, parents of children reported to snore habitually (n = 114) and an equal number of children who snored never or occasionally were given the Sleep Disturbance Scale for Children, a validated questionnaire for the assessment of pediatric sleep problems. Snoring status was re-assessed using the initial questionnaire and children were then classified as long-term habitual snorers or ex-habitual snorers. An increasing prevalence of sleep problems was found with increasing snoring frequency for sleep-onset delay, night awakenings, and nightmares. Long-term habitual snorers were at significantly increased risk for sleep,wake transition disorders (e.g. rhythmic movements, hypnic jerks, sleeptalking, bruxism; odds ratio, 95% confidence interval: 12.0, 3.8,37.3), sleep hyperhidrosis (3.6, 1.2,10.8), disorders of arousal/nightmares (e.g. sleepwalking, sleep terrors, nightmares; 4.6, 1.3,15.6), and excessive somnolence (i.e. difficulty waking up, morning tiredness, daytime somnolence; 6.3, 2.2,17.8). Ex-habitual snorers were at increased risk for sleep,wake transition disorders (4.4, 1.4,14.2). Habitual snoring was associated with several sleep problems in our study. Long-term habitual snorers were more likely to have sleep problems than children who had stopped snoring spontaneously. [source]

Skin problems in lower limb amputees: an overview by case reports

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 2 2007
HEJ Meulenbelt
Abstract The stump in lower limb amputees is prone to skin problems because it is exposed to several unnatural conditions (shear and stress forces and increased humidity) when a prosthesis is used. This study reviews the literature on case reports of lower limb amputees with skin problems on the stump. In total, 56 reports comprising 76 cases were identified in the literature. The main disorders are acroangiodermatitis, allergic contact dermatitis, bullous diseases, epidermal hyperplasia, hyperhidrosis, infections, malignancies and ulcerations. [source]

Ross syndrome, an entity included within the spectrum of partial disautonomic syndromes

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 6 2005
M Ballestero-Díez
ABSTRACT Ross syndrome is a degenerative peripheral nervous system disorder defined by the following triad: unilateral or bilateral segmental anhidrosis, hyporeflexia of deep tendon reflexes and Adie's tonic pupils. The most disturbing symptom is segmental compensatory hyperhidrosis. It has only occasionally been reported in the dermatological literature. We present a 35-year-old woman with chronic hepatitis C who developed the characteristic triad of Ross syndrome within 1 month. The patient was otherwise healthy except for an aneurysm of the left medium brain artery not responsible for the syndrome. [source]

The borderline syndrome in psychosomatic dermatology Overview and case report

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 4 2004
W Harth
ABSTRACT The borderline syndrome is one of the most severe disturbances of psychosomatic dermatology. Patients with borderline syndrome are situated ,on the border' of psychosis, neurosis and personality disorders. The skin as a borderline organ carries a symbolic role. The clinical picture includes artefactual skin diseases due to self-mutilation by conscious or unconscious cutting, and rubbing, scratching or para-artefactual manipulations of pre-existing dermatoses. Leading symptoms of the borderline syndrome are poor impulse control, emotional instability and poor ego strength with low frustration tolerance and unstable personal relationships. We present the case of a 38-year-old female patient with borderline syndrome suffering from para-artefactual skin diseases of the face and a massive hyperhidrosis of the hands and feet. Within 9 months she was treated in four acute psychiatric hospitals and by 12 psychiatrists and psychotherapists. Early and accurate diagnosis and high-quality, sophisticated long-term therapy are necessary. [source]

Botulinum toxin A for palmar hyperhidrosis

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 6 2001
U Wollina
Abstract Objective We evaluated the efficacy and safety of intracutaneous injections of botulinum toxin A on severe palmar hyperhidrosis. Methods Ten patients with recalcitrant palmar hyperhidrosis were treated with intercutaneous injections of botulinum toxin A (Botox; 200 U for each hand). Patients were followed up to 23 months (mean ± SD: 12.1 ± 6.2 months). Results Botulinum toxin significantly reduced abnormal sweating within 1 week in 100% of the patients. In six patients with a follow-up of 12 months or more the antisudorific effect lasted 12.3 ± 5.5 months. The longest response duration was 22 months. Repeated treatment was performed in five patients with unchanged clinical efficacy. The only side-effect was tolerable pain from the intracutaneous injections in patients where a nerve block was not performed. Conclusions Botulinum toxin A (200 U Botox per palm) was able to induce long-term remission in palmar hyperhidrosis without significant acute and long-term side-effects. Strictly intracutaneous injection of small volumes is recommended. So far, response to repeated treatments did not show evidence of neutralizing antibody induction. [source]

Diode laser hair removal does not interfere with botulinum toxin A treatment against axillary hyperhidrosis

LASERS IN SURGERY AND MEDICINE, Issue 3 2010
Anna Paul MD
Abstract Background and Objective The possible interference of combined laser hair removal and Botulinum toxin A (BoNT/A) injections in the treatment of axillary hyperhidrosis has not previously been explored. In order to examine this potential interference, we assessed the effect of BoNT/A on axillary hyperhidrosis with and without concomitant diode laser axillary hair removal. Study Design/Materials and Methods In a prospective, double blind, randomized cross over trial, nine patients suffering from primary axillary hyperhidrosis were laser-treated on one randomly assigned axilla. One week later, both axillas were injected intradermally with BoNT/A (100,MU per axilla). During the same session, the previously untreated axilla was lasered. Axillary sweat rates (in g/5,minutes.) were determined by gravimetry and compared at rest, during mental exercise, and during physical exercise. Additionally, subjective outcome measures were assessed by a visual analogue scale, Dermatology Life Quality Index, and Global Clinical Impression score. Results No differences were found regarding the effect of BoNT/A on previously laser-treated and laser co-treated sides over time course for any of the outcome parameters. Sweat production was reduced 3 weeks after BoNT/A treatment by 93.5% at rest, 96.5% during mental exercise, and 67% during physical exercise. Conclusions Concomitant laser hair removal does not interfere with BoNT/A treatment on axillary hyperhidrosis. Lasers Surg. Med. 42:211,214, 2010. © 2010 Wiley-Liss, Inc. [source]

Morvan's syndrome: Clinical, laboratory, and in vitro electrophysiological studies

MUSCLE AND NERVE, Issue 2 2004
Wolfgang N. Löscher MD
Abstract Morvan's syndrome is a rare disorder characterized by neuromyotonia, hyperhidrosis, and central nervous system dysfunction. We report a patient with features of this syndrome, but who initially presented with breathing difficulties. Concentric needle electromyography showed an abundance of myokymic and neuromyotonic discharges. Exercise tests and repetitive nerve stimulation showed a decrement,increment response of compound muscle action potentials. Antibodies against voltage-gated potassium channels were not detected on repeated testing, but the presence of oligoclonal bands in the cerebrospinal fluid (CSF) suggested an autoimmune etiology. At follow-up over 3 years, no cancer was found. Electrophysiological in vitro studies of effects of patient serum and CSF on rat nerves provided no evidence of altered voltage-gated sodium or potassium conductances. We conclude that putative humoral factors do not block ion channels acutely but may cause channel dysfunction with chronic exposure. Muscle Nerve 30: 157,163, 2004 [source]

Bilateral pulmonary edema after endoscopic sympathectomy in a patient with glucose-6-phosphate dehydrogenase deficiency

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2001
C.-J. Lan
Transaxillary endoscopic sympathectomy of thoracic ganglia (T2,T3) has recently gained wider acceptance as the treatment of choice for palmar hyperhidrosis. It requires one-lung ventilation to facilitate the surgery. One-lung ventilation, however, is not without complications, among which acute pulmonary edema has been reported. In this case report, we present a patient with palmar hyperhidrosis complicated by glucose-6-phosphate dehydrogenase (G-6-PD) deficiency, who received bilateral endoscopic sympathectomy under alternate one-lung anesthesia, and developed acute pulmonary edema immediately after recruitment of the successive collapsed lung. The effects of hypoxemia, G-6-PD deficiency and sympathectomy might all add to the development of acute pulmonary edema secondary to reexpansion of each individual lung after alternate one-lung ventilation. The possibilities of the inferred causes are herein discussed. [source]
