The comparison of VATS ramicotomy and VATS sympathicotomy for treating essential hyperhidrosis.
(25/177)
This study was undertaken to determine if better results could be achieved by comparing the results of a thoracic sympathetic ramicotomy (division of rami communicantes) with a conventional thoracic sympathicotomy (division of sympathetic trunk) for treating essential hyperhidrosis. From August 2001 to February 2002, 29 consecutive patients underwent surgery of the sympathetic nerves in order to treat severe essential hyperhidrosis. Of these patients, a ramicotomy was performed under VATS (VATS-R) in 13 patients, sympathicotomy under VATS (VATS-S) in 13, a unilateral ramicotomy and contralateral sympathicotomy under VATS (VATS-RS) in 2 and a sympathicotomy via a thoracotomy (T-S) in 1. There was no significant difference between the VATS ramicotomy group (VATS-R, n=13) and VATS sympathicotomy group (VATS-S, n=13) in terms of gender, pleural adhesions or comorbidities. However, the age of the VATS-S group at surgery was higher than that of the VATS-R group (p=0.050). The operation times, and hospital stays of the groups were 51.5 and 41.9 minutes, and 2.0 and 2.3 days, respectively. The recurrence rate of the operated sites according to the surgical methods (ramicotomy and sympathicotomy regardless of VATS) was 21.4% (6/28) in the ramicotomy group and 6.7% (2/30) in the sympathicotomy group, but there was no statistical significance (p=0.101). This study compared the dryness of the enervated sites and the severity of compensatory sweating among the ramicotomy (n=11, excluded 2 re-operated cases from 13 VATS-R), sympathicotomy (n=14, VATS-S 13 and T-S 1) and the synchronous or metachronous ramicotomy/sympathicotomy groups (n=4, included 2 reoperated cases of VATS-R). The sympathicotomy group had an over-dryness of the enervated sites (dryness 1.4, from 1 to 3; 1:over-dried, 2:humid, 3:persistent sweating) and complained of severe compensatory sweating (severity 3.5, from 1 to 4; 1:absent, 2:mild, 3:embarrassing, 4:disabling). However, the patients whounderwent a ramicotomy maintained some humidity of the enervated sites (dryness 2.0, p=0.012) and showed milder compensatory sweating (severity 2.7, p=0.056) than those in the sympathicotomy group. Furthermore, the dryness of the ramicotomy side was different from that of the sympathicotomy side in 3 out of 4 ramicotomy / sympathicotomy (R+S) patients (the side of the ramicotomy was humid and that of the sympathicotomy was over-dried). The average dryness and the compensatory sweating at these sites were in the midst of the two groups (dryness and severity 1.6 and 3.0, respectively). A ramicotomy can prevent over-dryness of the enervated area and decrease the severity of compensatory sweating through the selective division of the rami communicantes of the thoracic sympathetic ganglia. Postoperatively, almost all ramicotomy patients had no functional problems in daily life or in their occupational activity, because they could maintain hand humidity. Moreover, they showed no more than a mild degree of compensatory sweating and reported high long-term satisfaction rates. Therefore, a sympathetic ramicotomy rather than a conventional sympathicotomy is recommended as a more selective and physiologic modality for treating essential hyperhidrosis. (+info)
Acupuncture for the treatment of sweating associated with malignancy.
(26/177)
Acupuncture was used to treat a 60-year old woman with unexplained sweating associated with inoperable lung cancer that prevented her from sharing a bed with her husband. Other measures failed to improve her sweating, but she responded well to a course of acupuncture allowing her to continue sharing the marital bed. (+info)
Sudomotor function in familial dysautonomia.
(27/177)
BACKGROUND: Patients with familial dysautonomia (FD) manifest episodic hyperhidrosis despite the reduction of sudomotor fibres and sweat glands associated with this autonomic neuropathy. We assessed peripheral sudomotor nerve fibre and sweat gland function to determine if this symptom was due to peripheral denervation hypersensitivity. METHODS: In 14 FD patients and 11 healthy controls, direct and axon reflex mediated sweat responses were determined by measuring transepidermal water loss (TEWL) after application of acetylcholine via a microdialysis membrane, a novel method to evaluate sudomotor function in neuropathy patients. Results were compared with data from conventional quantitative sudomotor axon reflex testing (QSART). Using microdialysis, interstitial fluid was analysed for plasma proteins to evaluate protein extravasation induced by acetylcholine as an additional parameter of C-fibre function. RESULTS: Although reduced axon reflex sweating was expected in FD patients, neither direct or axon reflex mediated sweat responses, nor acetylcholine induced protein extravasation differed between control and patient groups. However, the baseline resting sweat rate was higher in FD patients than controls (p<0.05). TEWL and QSART test results correlated (r = 0.64, p = 0.01), proving the reliability of TEWL methodology in evaluating sudomotor function. CONCLUSION: The finding of normal direct and axon reflex mediated sweat output in FD patients supports our hypothesis that, in a disorder with severe sympathetic nerve fibre reduction, sudomotor fibres, but not the sweat gland itself, exhibit chemical hypersensitivity. This might explain excessive episodic hyperhidrosis in situations with increased central sympathetic outflow. (+info)
Management of postsurgical hyperhidrosis with direct current and tap water.
(28/177)
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. (+info)
Early experience with thoracoscopic sympathectomy for palmar hyperhidrosis.
(29/177)
Excessive craniofacial, palmar and axillary hyperhidrosis can be very distressing in young people, especially in hot climates. In this study, we are presenting our operative experience and the long-term effect of the technique of thoracospic electrocoagulation of the thoracic sympathetic chain in the treatment of this condition. We reviewed the results of 22 thoracoscopies performed on 16 patients at Asir Central Hospital in Abha, Saudi Arabia during the period from January 1999 to December 2002. The patients were 11 males and five females with a mean age of 26.9+/-5 years (range 19-35 years). Except for one patient who presented with post-traumatic, left upper limb chronic regional pain syndrome (CRPS), the rest presented with craniofacial, palmar and axillary hyperhidrosis. In the first 10 patients, sympathectomy was performed unilaterally and in the following six patients it was performed bilaterally in the same sitting. While pneumothorax occurred in three patients (19%), only one patient (6%) required chest tube insertion. During the mean follow-up period of 25.6+/-14.2 months (range 4-47 months), only one patient (6%) presented with recurrent left axillary hyperhidrosis. The patient underwent another thoracoscopy which failed due to lung adhesions and required subcutaneous electrocautery of the sweat glands. In conclusion, thoracoscopic sympathectomy is very effective (94%) in the treatment of palmar and axillary hyperhidrosis with no mortality, minimal morbidity and durable long-term effect. (+info)
Thoracoscopic sympathetic surgery for hand sweating.
(30/177)
Recently, thoracoscopic surgery has been shown to be effective for the relief of hand sweating. Although it is not fatal if left untreated, the treatment aim is to improve the quality of daily life. Therefore, it is important to understand the complaints of the patient, and provide an adequate explanation regarding postoperative sequelae. Surgeons should also recognize that thoracoscopic surgery might cause problems when performed, as the general risk of surgery remains. Many patients have been helped by the procedure, as their choices in life have expanded, and satisfactory results can be obtained when indication is determined by a full examination of the patients condition. Between December 1999 and September 2002, we performed thoracoscopic sympathetic surgery in 556 consecutive patients. Five-hundred seventeen (93%) of these complained of profuse hand sweating. Based on the new concept presented, we consider that this method of operation is an effective treatment. (+info)
Palmoplantar hyperhidrosis: a therapeutic challenge.
(31/177)
Excessive sweating from the palms and soles, known as palmoplantar hyperhidrosis, affects both children and adults. Diagnosis of this potentially embarrassing and socially disabling condition is based on the patient's history and visible signs of sweating. The condition usually is idiopathic. Treatment remains a challenge: options include topical and systemic agents, iontophoresis, and botulinum toxin type A injections, with surgical sympathectomy as a last resort. None of the treatments is without limitations or associated complications. Topical aluminum chloride hexahydrate therapy and iontophoresis are simple, safe, and inexpensive therapies; however, continuous application is required because results are often short-lived, and they may be insufficient. Systemic agents such as anticholinergic drugs are tolerated poorly at the dosages required for efficacy and usually are not an option because of their associated toxicity. While botulinum toxin can be used in treatment-resistant cases, numerous painful injections are required, and effects are limited to a few months. Surgical sympathectomy should be reserved for the most severe cases and should be performed only after all other treatments have failed. Although the safety and reliability of treatments for palmoplantar hyperhidrosis have improved dramatically, side effects and compensatory sweating are still common, potentially severe problems.

"Primary" aggressive chondroblastoma of the humerus: a case report.
(32/177)
BACKGROUND: Chondroblastomas are rare epiphyseal bone tumors. Very few cases with extra-cortical aggressive soft tissue invasion or metastasis are reported. CASE PRESENTATION: We report a 28 year-old adult male who presented with a large swelling over the left shoulder region. Pre-operative imaging revealed a large tumor arising from upper end of humerus with extensive soft tissue involvement necessitating a fore-quarter amputation. Patient received adjuvant radiation. CONCLUSIONS: This patient is one of the largest chondroblastomas to be reported. Although chondroblastomas are typically benign, rarely they can be locally aggressive or metastatic. Early diagnosis and institution of proper primary therapy would prevent mutilating surgeries and recurrences. (+info)
