Endoscopic thoracic sympathectomy for primary focal hyperhidrosis: impact on psycho-social symptomatology and psychotropic medication use.

OBJECTIVES: The tendency for patients with primary focal hyperhidrosis (PFH), characterized by excessive sweating, to experience psycho-social deficits is well documented. In addition, although endoscopic thoracic sympathectomy (ETS) effectively corrects PFH, its role in the psycho-social management of these patients remains unclear. Here, we examined changes in psychiatric symptomatology and psychotropic medication usage in PFH patients following ETS. METHODS: In total, 106 PFH patients underwent ETS and were compared against 213 matched controls. Information on psychiatric diagnosis and prescription was obtained through a retrospective chart review. Prospectively, PFH patients completed Hyperhidrosis Impact Questionnaires, Leibowitz Social Anxiety Scales and Center for Epidemiological Studies Depression Scales to evaluate pre- and postoperative quality-of-life and psycho-social impairment. RESULTS: A significantly greater proportion of PFH patients had been prescribed psychotropic medication (37.7%) compared to controls (14.1%) despite no differences in the proportion of psychiatric diagnoses. Following ETS, 52.5% of the PFH patients who were using psychotropic medications reduced their prescription regimen, compared to only 10% of control patients (P < 0.01). Additionally, scores improved dramatically in each Hyperhidrosis Impact Questionnaires category, and in both the Leibowitz Social Anxiety Scales and Center for Epidemiological Studies Depression Scales (P < 0.01). CONCLUSIONS: We demonstrate that in over half of PFH patients, psychotropic medication usage was discontinued after ETS, which is consistent with our findings on postoperative improvements in Hyperhidrosis Impact Questionnaires, Leibowitz Social Anxiety Scales and Center for Epidemiological Studies Depression Scales scores. Furthermore, our findings suggest that a considerable proportion of PFH patients who experience psychopathology may be doing so secondary to excessive sweating. Thus, improved awareness or recognition of these associations in the diagnosis and management of PFH patients is warranted.

Guidelines for glycerol use in hyperhydration and rehydration associated with exercise.

Dehydration in athletes alters cardiovascular and thermoregulatory function and may inhibit endurance exercise capacity if fluid loss exceeds 2% of bodyweight (BW). If this level of dehydration cannot be prevented when starting from a state of euhydration, then athletes may create a state of hyperhydration by consuming extra fluid prior to exercise. From this hyperhydrated situation, individuals have a greater capacity to tolerate fluid loss before becoming dehydrated. Furthermore, excess pre-exercise fluid intake enhances thermoregulatory ability, as well as increasing plasma volume to maintain cardiac output. However, hyperhydrating before exercise is difficult, because a large fluid intake is typically accompanied by diuresis. Glycerol-containing beverages create an osmotic gradient in the circulation favouring fluid retention, thereby facilitating hyperhydration and protecting against dehydration. Many studies have shown that increases in body water by 1 L or more are achievable through glycerol hyperhydration. This article analyses the evidence for glycerol use in facilitating hyperhydration and rehydration, and provides guidelines for athletes wishing to use this compound. An analysis of the studies in this area indicates that endurance athletes intending to hyperhydrate with glycerol should ingest glycerol 1.2 g/kg BW in 26 mL/kg BW of fluid over a period of 60 minutes, 30 minutes prior to exercise. The effects of glycerol on total body water when used during rehydration are less well defined, due to the limited studies conducted. However, ingesting glycerol 0.125 g/kg BW in a volume equal to 5 mL/kg BW during exercise will delay dehydration, while adding glycerol 1.0 g/kg BW to each 1.5 L of fluid consumed following exercise will accelerate the restoration of plasma volume. Side effects from glycerol ingestion are rare, but include nausea, gastrointestinal discomfort and light-headedness. In summary, glycerol ingestion before, during or following exercise is likely to improve the hydration state of the endurance athlete.

Electroterapia, hiperhidrosis y enfermedades neurovasculares / Electrotherapy, hyperhidrosis and neurovascular diseases

Los síndromes vasoespásticos son alteraciones vasculares que afectan a las extremidades, principalmente las superiores; tienen carácter funcional y, como denominador común, su sintomatología está producida por un aumento de la capacidad vasoconstrictiva de etiología poco conocida. Entre los factores precipitantes se encuentran la exposición al frío y los estímulos emocionales. La exploración generalmente muestra, entre las crisis, dedos fríos y lividez con hiperhidrosis. Los objetivos de nuestro estudio son exponer la evolución antes y después del tratamiento del cortejo sintomático acompañante de la hiperhidrosis palmar, como la hipotermia y la lividez en los pacientes que la sufren. Para cumplir los objetivos, se planteó un estudio experimental con sendos grupos: control normal de 10 pacientes sin tratamiento y experimental con un total de 60 pacientes con hiperhidrosis, distribuidos en 6 subgrupos y sometidos a tratamiento de iontoforesis con agua corriente. Los resultados obtenidos indican que, aunque la terapéutica aplicada suprimió en el 100% de los casos el problema de la hipersudación palmar que presentaban los pacientes, no se obtuvo un paralelismo en los resultados del cortejo clínico acompañante, lo que confirma cierta idiosincrasia evolutiva en los pacientes con hiperhidrosis y problemas vasomotores en partes acras(AU)

Vasospastic syndromes are vascular alterations affecting the limbs, mainly the upper ones. They have a special function, that is, they are functional and have a common denominator that is produced by their symptoms due to an increase in vasoconstrictor capacity whose etiology is little known. Exposure to cold and emotional stimuli is among its precipitating factors. The examination generally shows cold fingers and lividness with hyperhidrosis among the episodes. The goals outlined in our study are exposing the pre and post therapeutic course of the main symptoms accompanying the palmar hyperhidrosis, such as hypothermia and lividness in patients with osteoporosis. In order to fulfill the objectives, a pilot study was proposed with two groups: control group of 10 patients without normal and experimental treatment and a total of 60 patients with hyperhidrosis, divided into 6 subgroups who underwent treatment with tap water iontophoresis. The results obtained suggest that although the therapy applied eliminated the problem of palmar hyperhidrosis presented by the patients in all of the cases, a parallel result was not obtained in the main accompanying symptoms, confirming some evolutionary idiosyncrasy in patients with hyperhidrosis and acral vasomotor problems(AU)

Introducción: El síndrome de Raynaud primario consiste en un complejo sintomático secundario a vasospasmo vascular periférico en respuesta a un estímulo térmico frío y/o emocional, en las partes acras del cuerpo, cuya prevalencia en adultos varía entre el 3,7 y el 13%. Objetivos: Analizar la sintomatología y la topografía de la manifestación del síndrome de raynaud, así como conseguir una sudación normal mediante el protocolo de tratamiento diseñado. Resultados: Reducción significativa del sudor en un 66%, con disminución del número de crisis y aumento de los periodos intercríticos; se consiguió coloración normocrómica y desaparición de las fases de cambio cromático. Conclusiones: Los hallazgos termohigrométricos y colorimétricos nos inducen a considerar la modalidad electroterapéutica de iontoforesis con agua corriente como un procedimiento eficaz a largo plazo que permite conseguir una euhidrosis de la zona afecta, así como una mejora de los cambios vasculares relacionados con la enfermedad de Raynaud(AU)

Introduction: Primary Raynaud's syndrome consists in a symptomatic complex secondary to peripheral vasospasm in response to cold thermal stimulus and/or emotional stimulus in the distal parts of the body whose prevalence in adults varies from 3.7% to 13%. Objectives: To analyze the symptoms and topography of the manifestation of Raynaud's syndrome, as well as the achieving of normal sweating by the treatment protocol designed. Results: There is a significant reduction of perspiration, that is 66%, with a decrease in the number of episodes and increase of the periods between episodes, achieving normochromic coloring with the disappearance of the phases of chromatic change. Conclusions: The thermohygrometric and colorimetric findings lead us to consider iontophoresis electrotherapy with running water as a long-term effective procedure that makes it possible to achieve hidrosis of the affected area and improvement in the vascular changes associated to Raynaud's disease(AU)

Side effects, complications and outcome of thoracoscopic sympathectomy for palmar and axillary hyperhidrosis in 406 patients.

BACKGROUND: Thoracic sympathectomy (TS) is the treatment of choice for severe primary hyperhidrosis. However, complications, side effects and satisfaction have not been well defined. OBJECTIVE: To analyze the complications, side effects, satisfaction degree and quality of life of patients after TS for primary upper limb hyperhidrosis. METHODS: One-year follow-up after 406 consecutive TS for primary upper limb hyperhidrosis. RESULTS: Bilateral TS was completed in all patients. Complications arose in 23 cases (5.6%), with pneumothorax being the most frequent. The success rate after discharge, 6 and 12 months was respectively, 100%, 98.1% and 96.5% for palmo-axillary hyperhidrosis; 100%, 99.3% and 97.8% for isolated palmar hyperhidrosis and 100%, 85.7% and 71.4% for isolated axillary hyperhidrosis. No persistence of hyperhidrosis was observed. Global recurrence was 3.7% (28.5% axillary hyperhidrosis group). Compensatory sweating (CS) appeared in 55% and was not related to the extension of the TS. Being female was a predisposing factor of CS (p<0.004). Excessive dryness appeared at 9% and was associated with extensive TS (P<0.001). Plantar hyperhidrosis improved at 33.6%, worsened at 10% and remained stable during the follow-up. Satisfaction degree decreased with the passage of time and was associated with recurrence. Quality of life was excellent at discharge, 6 and 12 month in 100%, 100% and 97%, respectively. CONCLUSIONS: Pneumothorax is the most frequent complication of TS. CS is the main and undesirable side effect, appears with the passage of time, and is not related to the extension of TS. Being female is the only predictor factor of suffering CS. Plantar hyperhidrosis improves initially, although tends to reappear. Excessive dryness appears in extensive TS and does not improve over time. Postoperative satisfaction degree is high but decreases over time owing to the appearance of recurrence. Effectiveness and the absence of CS determine an excellent quality of life. Six percent of the patients regret the surgery because of severe CS. Informing patients of possible side effects before TS is essential.

An assessment of anxiety in patients with primary hyperhidrosis before and after endoscopic thoracic sympathicolysis.

OBJECTIVE: Endoscopic bilateral thoracic sympathicolysis (EBTS) is an effective and minimally invasive procedure used for patients with primary hyperhidrosis. The purpose of this study was to examine anxiety levels using standardized psychometric tools in hyperhidrosis patients before and after EBTS. METHODS: A total of 106 patients diagnosed with hyperhidrosis who underwent EBTS were asked to fill out a questionnaire before and 12 months after the procedure that elicited the following information: (a) symptoms associated with hyperhidrosis; (b) the patient's level of anxiety; and (c) the extent to which this anxiety was incapacitating in their daily life. All patients also completed State-Trait Anxiety Inventory (STAI) before and 12 months after the EBTS. RESULTS: Palpitations were reported preoperatively by 40% of patients versus 10% postoperatively, trembling of the hands in 24% versus 8%, facial blushing in 55% versus 11%, headache in 29% versus 9%, and non-specific epigastric pain in 19% versus 7%. Patients reported a marked improvement in the level of anxiety from a mean SD of 2.08+/-1.1 preoperatively versus 0.39+/-0.67 postoperatively (p<0.001), and the social impact (debilitating) of primary hyperhidrosis before and after surgery also showed significant improvement (p<0.001). The results of STAI showed significant improvement in the levels of anxiety after surgery compared with the preoperative levels and with established norms (p<0.001). CONCLUSIONS: Patients with primary hyperhidrosis that undergo EBTS presented a decrease in the level of anxiety and associated symptoms.

Psychosocial aspects of patients with focal hyperhidrosis. Marked reduction of social phobia, anxiety and depression and increased quality of life after treatment with botulinum toxin A.

BACKGROUND: Primary focal hyperhidrosis (PFH) is defined as excessive sweating typically localized to specific body areas such as axillae, hands and feet. An association between PFH and anxiety as well as depressive syndromes has been suggested. OBJECTIVES: To investigate a possible association between PFH and anxiety, depression, social phobia and quality of life, and to study the effect of treatment with botulinum toxin A on these factors. METHODS: PFH was confirmed clinically and by gravimetry. To measure anxiety and depressive syndromes several German versions of standardized questionnaires were used: State-Trait Anxiety Inventory G Form X2 (STAI), Social Phobia Scale (SPS), Symptom Checklist of Derogatis (SCL-90-R), subscales 'Social Insecurity', 'Depression', 'Anxiety' and 'Phobia', and Hospital Anxiety and Depression Scale (HADS-D). Quality of life was assessed using Skindex. Two analyses were performed. The first analysis included all patients with PFH, the second analysis only patients with PFH who were treated with botulinum toxin A. In the latter group the questionnaires were repeated 2-4 weeks after treatment. RESULTS: For the total group at baseline the values for STAI, SCL-90-R, HADS-D and SPS were well within the normal range. However, in the group of patients treated with botulinum toxin A, the mean +/- SD SPS score was 17.6 +/- 15.5, i.e. above the normal range. Quality of life was impaired, with a mean +/- SD Skindex score of 24.3 +/- 5.7 at baseline. Treatment with botulinum toxin A led to a significant reduction in all investigated symptoms. CONCLUSIONS: Despite an impaired quality of life, patients with PFH in general do not show increased symptoms of anxiety, depression or social phobia. Only in the subgroup of patients treated with botulinum toxin A was the SPS increased at baseline. Treatment with botulinum toxin A led to a marked improvement in all factors investigated.

Management of postsurgical hyperhidrosis with direct current and tap water.

BACKGROUND AND PURPOSE: Excessive sweating, known as hyperhidrosis, involves the eccrine sweat glands of the axillae, soles, palms, and/or forehead. The use of iontophoresis to reduce or eliminate excessive sweating has been described since 1952. The purpose of this case report is to describe the use of tap water galvanism (TWG) using direct current (DC) with a patient who had postsurgical hyperhidrosis. CASE DESCRIPTION: The patient was a 36-year-old male electrician with traumatic phalangeal amputation and postsurgical development of hyperhidrosis. Tap water galvanism was administered using a DC generator, 2 to 3 times per week for 10 treatments. The patient's hands were individually submerged in 2 containers of tap water with the electrodes immersed directly into the containers. Each hand was treated with 30 minutes of TWG at 12 mA. Hyperhidrosis was measured by a 5-second imprint and subsequent tracing of the left hand placed on dry paper toweling. OUTCOMES: The patient's hyperhidrosis decreased from the full left palmar pad, with a surface area of 10.3x12.0 cm, to a reduced area of wetness that covered a 2.2-x2.7-cm area. The patient returned to work as an electrician without needing absorbent gloves, which had prevented him from performing electrical work. DISCUSSION: Following use of TWG, the patient's palmar hyperhidrosis returned to normhidrosis.

Effect of botulinum toxin type A on quality of life measures in patients with excessive axillary sweating: a randomized controlled trial.

BACKGROUND: Botulinum toxin type A (BTX-A) has been shown to be a safe and effective treatment for primary focal hyperhidrosis. However, the effect of BTX-A therapy on quality of life (QOL) in patients with this condition has only recently begun to be studied in controlled clinical trials. OBJECTIVES: To assess the impact on QOL of BTX-A treatment in patients with bilateral primary axillary hyperhidrosis. METHODS: A multicentre, randomized, double-blind, placebo-controlled trial enrolled 320 patients who exhibited persistent, bilateral, primary axillary hyperhidrosis sufficient to interfere with daily activities. These patients were treated with either 50 U BTX-A (Botox, Allergan, Inc., Irvine, CA, U.S.A.) or placebo in each axilla. QOL was assessed using the Hyperhidrosis Impact Questionnaire (HHIQ) at baseline and 1, 4, 8, 12 and 16 weeks post-treatment, as well as the Medical Outcomes Trust Short Form-12 Health Survey(SF-12) at baseline and 16 weeks post-treatment. RESULTS: At baseline, participants reported a marked negative impact of hyperhidrosis on various measures, including emotional status, ability to participate in daily and social activities, productivity at work and number of clothing changes per day. During the post-treatment period, statistically and clinically significantly greater improvements in all of these parameters were observed for the BTX-A group compared with the placebo group (P < 0.01). The BTX-A group improvements were observed within 1 week of treatment, and were sustained with little or no decline throughout the 16-week follow-up period. Compared with the baseline HHIQ responses regarding treatment history, BTX-A treatment resulted in a greater level of overall treatment satisfaction than did many other hyperhidrosis treatments. In addition, patients treated with BTX-A exhibited statistically significantly greater improvement in the physical component summary score of the SF-12 at 16 weeks than did placebo-treated patients (P < or = 0.019). CONCLUSIONS: Hyperhidrosis is associated with a substantial QOL burden; however, QOL is markedly improved with BTX-A treatment.

[Modification and optimization of tap water iontophoresis]. / Modifikation und Optimierung der Leitungswasser-Iontophorese.

Tap water iontophoresis is the therapy of choice in hyperhidrosis palmoplantaris. Therapeutic regimens, however, vary greatly. The aim of the present study was to develop an optimized therapeutic scheme. The main methodologic parameters subjected to systematic experimental study included the effects of current polarity, the duration of a single treatment session, the addition of electrolytes to the tap water and the treatment interval during maintenance therapy. The following procedure is proposed. During the initial phase, treatments are carried out three times weekly for 10 min each time. The anode is kept on one extremity until normhidrosis is reached on this extremity. Then, polarity is changed until sweating is reduced to normal on the other extremity (constant polarity). In the subsequent maintenance phase, patients are treated at intervals of 6-8 days for 10 min each time. Polarity is switched from treatment to treatment (alternating polarity). Plain tap water is used without additives.
