Primary plantar hyperhidrosis is defined as excessive secretion of the sweat glands of the feet and may lead to significant limitations in private and professional lifestyle and reduction of health-related quality of life. Conservative therapy measures usually fail to provide sufficient relieve of symptoms and do not allow long-lasting elimination of hyperhidrosis. Endoscopic lumbar sympathectomy appears to be a safe and effective procedure for eliminating excessive sweating of the feet and improves quality of life of patients with severe plantar hyperhidrosis.

Background The mechanism of compensatory hyperhidrosis remains unclear. The aim of this study was to explore the relationship between compensatory hyperhidrosis and thoracic sympathetic ganglion excitability to assess the effectiveness of thoracoscopic T4 sympathicotomy for treating palmar hyperhidrosis. Methods Sixty-six cases of T4 sympathetic ganglions were prospectively collected from patients with palmar hyperhidrosis who underwent thoracoscopic T4 sympathicotomy from 2013 to 2016 in our department. The expression levels of choline acetyltransferase (ChAT), vasoactive intestinal peptide (VIP), and synaptophysin were detected using immunohistochemistry. Patients with palmar hyperhidrosis were followed-up for examination of postoperative sweating status. Results Thirty-eight cases (57.6%) of compensatory hyperhidrosis were identified. Mild compensatory hyperhidrosis occurred in 26 patients (39.4%), moderate in 11 (16.7%), and severe in 1 (1.5%). The rate of compensatory hyperhidrosis was higher in patients with axilla hyperhidrosis than those without (76.0% vs. 46.3%, P=0.018). However, the clinical data were similar between the compensatory hyperhidrosis group and the no compensatory hyperhidrosis group. In addition, the ChAT, VIP, and synaptophysin expression levels were not significantly different between the two groups (P values of 0.356, 0.071, and 0.141, respectively). Furthermore, the ChAT, VIP, and synaptophysin expression levels in the mild group were similar to those observed in the moderate/intense group (P values of 0.089, 0.124, and 0.149, respectively). The remission rate was 100% in palmar hyperhidrosis, 48.2% (27/56) in pedal hyperhidrosis, 56.0% (14/25) in axilla hyperhidrosis and 88.9% (16/18) in skin symptoms. No signs of chapped skin on the palms were found. Conclusions There was no significant correlation between compensatory hyperhidrosis and thoracic sympathetic ganglion excitability; however, compensatory hyperhidrosis is more likely to

Studies have suggested that quality of life (QOL) evaluation before video-assisted thoracoscopic sympathectomy for patients with hyperhidrosis may serve as a predictive factor for positive postoperative outcomes. Our study aims to analyze if this tendency is also observed in patients treated with oxybutynin for palmar and axillary hyperhidrosis. Five hundred sixty-five patients who submitted to a protocol treatment with oxybutynin were retrospectively analyzed between January 2007 and January 2012 and were divided into 2 groups according to QOL assessment before treatment. The groups consisted of 176 patients with "poor" and 389 patients with "very poor" QOL evaluation before oxybutynin treatment. Outcomes involving improvements in QOL and clinical progression of hyperhidrosis were evaluated using a validated clinical questionnaire that was specifically designed to assess satisfaction in patients with excessive sweating. Improvements in hyperhidrosis after oxybutynin were observed in 65.5% of patients with very poor pretreatment QOL scores and in 75% of patients with poor pretreatment QOL scores, and the only adverse event associated with oxybutynin treatment was dry mouth, which was observed with greater intensity in patients with very poor initial QOL evaluation. Improvements in hyperhidrosis after oxybutynin treatment were similar in both groups, suggesting that QOL before treatment is not a predictive factor for clinical outcomes, contrasting with surgical results that disclose significantly better results in patients with initially poorer QOL analysis.

Thoracic sympathectomy for hyperhidrosis: from surgical indications to clinical results

PubMed Central

Araújo, José Augusto

2017-01-01

Sympathectomy and its variations have been performed in thoracic surgery for more than 100 years. However, its indications have undergone profound modifications in this period. Likewise, since then the surgical technique has also evolved dramatically up to the minimally invasive techniques worldwide accessible in present days. Currently, primary hyperhidrosis is, by far, the main indication for thoracic sympathectomy and this procedure is usually carried out thoracoscopically with excellent results. However, until today, hyperhidrosis is a part of thoracic surgery still surrounded by controversy, persisting as an open field over which some confusion still resides regarding its pathophysiology, terms definitions and operative approaches. The aim of this article is to provide a wide but easily comprehensible review of the theme, discussing and clarifying the major concepts with respect to its clinical presentation, all the presently available treatment options and strategies with their potential benefits and risks, the adequate patient selection for sympathectomy, as well as the postoperative clinical results.

INTRODUCTION Thorascopic sympathectomy is accepted as an effective treatment for palmar hyperhidrosis, facial blushing and to a lesser extent for digital ischaemia and axillary hyperhidrosis. PATIENTS AND METHODS Data were collected retrospectively on patients undergoing thorascopic sympathectomy at St Peter's Hospital between 1987 and 2006. Patients were followed up by telephone interview. RESULTS A total of 233 thorascopic sympathectomy procedures were performed by a single operator in 123 patients. Ages ranged from 9–71 years and 75 were women. In patients, 105 had a bilateral and 13 a unilateral procedure, 5 patients had a bilateral procedure performed in two stages. In 6 upper limbs, the procedure could not be done. Overall, 110 patients (90%) had the procedure performed for palmar hyperhidrosis, 8 (6%) for facial blushing and in 5 (4%) patients the operation was performed for digital ischaemia with tissue loss. There were no deaths and all patients were discharged on day 1 following the procedure. Complications included bleeding (2), pulmonary oedema (1) and failed procedure (2); however, no incidences of Horner's syndrome occurred. Only 40 of 123 (32.5%) patients gave follow-up information. Of this small group, 33 of 40 (83%) were cured, 4 of 40 (10%) were better, 2 of 40 (5%) were unchanged and 1 patient was worse. Only 22 out of 40 (55%) of these patients were troubled by compensatory sweating, with only 4 of 40 (10%) reporting this as a major problem. CONCLUSIONS Thorascopic sympathectomy is safe and can be carried out as a single bilateral procedure in the majority of cases. The laser allows the use of a single port, requires less dissection than surgical or clipping techniques, is more precise than diathermy and may be less likely to cause a Horner's syndrome.

OBJECTIVE: Hyperhidrosis is a common disease, and thoracoscopic sympathectomy improves its symptoms in up to 95% of cases. Unfortunately, after surgery, plantar hyperhidrosis may remain in 50% of patients, and compensatory sweating may be observed in 70%. This clinical scenario remains a challenge. Our objective was to evaluate the effectiveness of oxybutynin in the treatment of persistent plantar hyperhidrosis and compensatory sweating and its effects on quality of life in women after thoracoscopic sympathectomy. METHOD: We conducted a prospective, randomized study to compare the effects of oxybutynin at 10 mg daily and placebo in women with persistent plantar hyperhidrosis. The assessment was performed using a quality-of-life questionnaire for hyperhidrosis and sweating measurement with a device for quantifying transepidermal water loss. Clinicaltrials.gov: NCT01328015. RESULTS: Sixteen patients were included in each group (placebo and oxybutynin). There were no significant differences between the groups prior to treatment. After oxybutynin treatment, there was a decrease in symptoms and clinical improvement based on the quality-of-life questionnaire (before treatment, 40.4 vs. after treatment, 17.5; p = 0.001). The placebo group showed modest improvement (p = 0.09). The outcomes of the transepidermal water loss measurements in the placebo group showed no differences (p = 0.95), whereas the oxybutynin group revealed a significant decrease (p = 0.001). The most common side effect was dry mouth (100% in the oxybutynin group vs. 43.8% in the placebo group; p = 0.001). CONCLUSION: Oxybutynin was effective in the treatment of persistent plantar hyperhidrosis, resulting in a better quality of life in women who had undergone thoracoscopic sympathectomy. PMID:24519200

OBJECTIVES Patients diagnosed with axillary hyperhidrosis can face psychosocial issues that can ultimately hinder their quality of life both privately and socially. The routine treatment for axillary hyperhidrosis is T3–T4 sympathectomy, but compensatory sweating is a serious side effect that is commonly seen with this approach. This study was designed to evaluate whether a T3 sympathectomy was effective for the treatment of axillary hyperhidrosis and whether this treatment led to less compensatory sweating than T3–T4 sympathectomies among our 60-patient population. METHODS One hundred and twenty endoscopic thoracic sympathectomies were performed on 60 patients who had axillary hyperhidrosis. The sympathectomies were accomplished by means of a single-lumen endotracheal tube and a single port. The axillary hyperhidrosis patients were randomly divided into two groups with 17 patients in Group 1 undergoing T3–T4 sympathectomies and 43 in Group 2 undergoing only T3 sympathectomies. We analysed the data associated with the resolution of axillary hyperhidrosis, the degree of patient satisfaction with the surgical outcome and the quality of life in parallel with compensatory sweating after the procedure as reported by the patient and confirmed by the examiner. Moreover, the results were compared statistically. RESULTS No statistically significant difference was observed between the groups based on age (P = 0.56), gender (P = 0.81), duration of the surgery (P = 0.35) or postoperative satisfaction levels (P = 0.45). However, the incidence and degree of compensatory sweating were lower in the T3 group than the T3–T4 group at the 1-year follow-up (P = 0.008). CONCLUSIONS T3 sympathectomy was as effective as T3–T4 sympathectomy for the treatment of axillary hyperhidrosis based on the patients’ reported postoperative satisfaction, and the T3 group demonstrated lower compensatory sweating at the 1-year follow-up.

Iontophoresis is a safe, efficacious, and cost-effective primary treatment of palmar and plantar hyperhidrosis. Decades of clinical experience and research show significant reduction in palmoplantar excessive sweating with minimal side effects. To get the best results from iontophoresis, health care professionals need to provide education on the mechanism of action and benefits, evidence of its use, and creation of a future patient-specific plan of care for continued treatments at home or in the physician's office. Iontophoresis may be combined with other hyperhidrosis treatments, such as topical antiperspirants and botulinum toxin injections. Copyright © 2014 Elsevier Inc. All rights reserved.

Rieger, Roman; Pedevilla, Sonja; Lausecker, Johannes

2015-04-01

Primary plantar hyperhidrosis is characterised by excessive secretion of the sweat glands of the feet and may lead to significant limitations in private and professional lifestyle. The aim of this prospective study was to assess the effect of endoscopic lumbar sympathectomy (ESL) on the quality of life (QL) of patients with primary plantar hyperhidrosis. Bilateral ESL was performed on 52 patients, 31 men and 21 women with primary plantar hyperhidrosis. Perioperative morbidity and clinical results were evaluated in all patients after a mean follow-up of 15 months. Postoperative QL was examined with the SF-36V2 questionnaire and the hyperhidrosis-specific questionnaires devised by Milanez de Campos and Keller. All procedures were carried out endoscopically with no perioperative morbidity. Plantar hyperhidrosis was eliminated in 50 patients (96%) and two patients (4%) suffered a relapse. Unwanted side effects occurred in the form of compensatory sweating in 34 (65%) and in the form of postsympathectomy neuralgia in 19 patients (37%). Ninety six percentage of patients were satisfied with the postoperative result and 88% would have the surgery repeated. The SF-36V2 questionnaire revealed a significant improvement of QL after lumbar sympathectomy in physical health (physical component summary, p < 0.01) as well as mental health (mental component summary, p < 0.05). Improved QL was also demonstrated in the Milanez de Campos questionnaire in the dimensions functionality/social interactions (p < 0.01), intimacy (p < 0.01), emotionality (p < 0.01) and specific circumstances (p < 0.01) as well as in the Keller questionnaire in the area of plantar hyperhidrosis (p < 0.01). The performance of an ESL in patients with primary plantar hyperhidrosis leads to the effective elimination of excessive sweat secretion of the feet and to an increase in QL.

Primary hyperhidrosis is an excessive sweating due to an overactive sympathetic system. Our objective was to test the feasibility and provide early data on the safety/efficacy of CT-guided sympatholysis, for primary hyperhidrosis. Nine consecutive patients with axillary-palmar hyperhidrosis were treated between 2013 and 2015. CT-guided sympathetic block was performed in the outpatients at T-2, T-3, and T-4, bilaterally using alcohol under local anesthesia. Immediate postprocedure CT was obtained to assess the complications as per Common Terminology Criteria for Adverse Events, version 4. Technical success and clinical success were recorded. Primary and secondary efficacy were assessed by phone and clinical visits; mean follow-up was 12 months (6-26 months). Descriptive statistics was used to report the outcomes. One procedure was aborted due to eyelid ptosis after lidocaine injection. All other eight patients (5:3, F:M) (median age 32) had immediate cessation of sweating. Two major complications (pneumothorax, one requiring a chest tube) occurred. Two patients recurred with unilateral and one with bilateral symptoms. One of the unilateral recurrence and the bilateral recurrence patients was retreated successfully. Median follow-up was 1 year. No cases of Horner's or compensatory hyperhidrosis were observed. CT-guided EtOH sympatholysis for axillary/palmar primary hyperhidrosis is feasible. Technical failure rate was 11 %. Primary and secondary efficacy are 75 and 94 %, respectively, to a median follow-up of 1 year. Risk profile appears favorable. Despite a small sample size, results confirm feasibility and encourage a larger study.

The objective of this study is to investigate the feasibility and safety of single-port microthoracoscopic thoracic sympathicotomy for the treatment of palmar hyperhidrosis. Between January 2008 and March 2013, 56 patients (36 male, 20 female; mean age 25.6 years, age range 16-39 years) underwent single-port microthoracoscopic thoracic sympathicotomy for palmar hyperhidrosis. Nineteen patients (33.9 %) had moderate palmar hyperhidrosis that could thoroughly wet a handkerchief, and 37 (66.1 %) had severe palmar hyperhidrosis with sweat dripping from the palm. Eight patients (14.3 %) had a positive family history, 34 (60.7 %) had plantar hyperhidrosis, 22 (39.3 %) had axillary hyperhidrosis, and 20 (35.7 %) had both plantar and axillary hyperhidrosis. In addition, 21 patients (37.5 %) had palmar pompholyx, five (8.9 %) had keratolysis exfoliativa, 10 (17.9 %) had chilblains, and nine (16.1 %) had palmar rhagades. A single 10-mm skin incision was made in the third intercostal space at the anterior axillary line, posterior to the pectoralis muscle. A 5-mm microthoracoscope and a 3-mm microelectrocautery hook were inserted through a single port into the thoracic cavity. The third and fourth ribs were identified, and the sympathetic chain was cut using the microelectrocautery hook. The bypassing nerve fibers, such as the Kuntz nerve fiber bundle, were ablated for 2-3 cm along the surface of the rib. The palmar temperature was recorded before and after sympathicotomy. All 56 procedures were completed using single-port microthoracoscopy. No postoperative complications such as hemorrhage, wound infection, hemopneumothorax, bradycardia, or Horner's syndrome were observed. Bilateral procedures were completed in 20-56 min (mean 30 min). The palmar temperature increased by 2.2 ± 0.3 °C after surgery. The postoperative hospital stay was 1-4 days (mean 2.5 days). Mild compensatory sweating of the back and thigh occurred in five patients (8.9 %) at 2-3�

Primary hyperhidrosis interferes with social activities and requires an effective and safe treatment. We aimed to compare the therapeutic outcomes of unilateral single-port sympathicotomy and open surgery. Forty patients with primary palmar hyperhidrosis underwent sympathicotomy; 20 had open surgery, and 20 had video-assisted thoracic surgery. Complete resection of the T1 to T4 ganglia was performed by open surgery, and cutting and cauterization of the sympathetic chain between the T2 and T3 ganglia in the dominant hand was undertaken using video-assisted thoracic surgery. The patients were followed up at 1, 3, 6, and 12 months after surgery. The mean operative times were 39.6 ± 1.46 and 79.8 ± 1.53 min in the video-assisted thoracic surgery and open surgery group, respectively. The mean hospitalization was 2.2 ± 0.41 days after video-assisted thoracic surgery and 3.3 ± 0.47 days after open surgery. Complications included delayed hemothorax, compensatory hyperhidrosis, and wound infection. The mean blood loss during surgery and time to return to work were significantly less in the video-assisted thoracic surgery group. Excessive sweating was completely alleviated in the dominant hand in all patients, and in the opposite hand in 60% and 65% of the video-assisted thoracic surgery and open surgery group, respectively. Single-port sympathicotomy between the T2 and T3 ganglia ipsilateral to the dominant hand is a safe, minimally invasive, and effective treatment for primary palmar hyperhidrosis. Alleviation of excessive sweating in the opposite hand can also be achieved in a large proportion of these patients. © The Author(s) 2016.

To analyze the efficacy of different surgical methods in treating palmar hyperhidrosis and the compensatory hyperhidrosis after surgery and to observe the efficacy of "Energy-boosting and Yin-nourishing anti-perspirant formula" on postsurgical hyperhidrosis patients. Two-hundred patients were randomly assigned to groups A (Chinese and Western medicine, T4 transection plus "Energy-boosting and Yin-nourishing anti-perspirant formula") and B (Western medicine, T4 transection). The surgical efficiency, recurrence rate, compensatory hyperhidrosis, and the long-term life quality were compared. Another 100 cases (group C, T2 transection) were analyzed as a control group. After surgery, the palmar hyperhidrosis and armpit sweating were relieved in all the three group patients and in 34 % of patients combined with plantar hyperhidrosis, the symptoms were relieved. Transient palmar hyperhidrosis was found in three cases at day 2 to day 5 postoperatively. One case of Horner's syndrome and one case recurrence were found in group C patients. The compensatory sweating of various degrees occurred in all the three groups. There were 25, 24, and 43 cases in groups A, B, and C, respectively. There is a significant difference between groups C, A, and B. The compensatory sweating in 13 cases of group A and four cases of group B had different degrees of improvement in the follow-up 6 months after surgery. There is a significant difference. Thoracoscopic bilateral T4 sympathetic chain and the Kuntz resection are the optimized surgical treatments for the palmar hyperhidrosis. "Energy-boosting and Yin-nourishing anti-perspirant formula" is effective in treating the postoperative compensatory sweating.

OBJECTIVE: To review surgical results of endoscopic transthoracic limited sympathotomy for palmar-plantar hyperhidrosis during the past decade. PATIENTS AND METHODS: We retrospectively reviewed 155 consecutive patients who underwent surgery from June 30, 2000, through December 31, 2009, for medically refractory palmar-plantar hyperhidrosis using a technique of T1-T2 sympathotomy disconnection, designed for successful palmar response and minimization of complications. RESULTS: Of the 155 patients, 44 (28.4%) were male, and 111 (71.6%) were female; operative times averaged 38 minutes. No patient experienced Horner syndrome, intercostal neuralgia, or pneumothorax. The only surgical complication was hemothorax in 2 patients (1.3%); in 1 patient, it occurred immediately postoperatively and in the other patient, 10 days postoperatively; treatment in both patients was successful. All 155 patients had successful (warm and dry) palmar responses at discharge. Long-term follow-up (>3 months; mean, 40.2 months) was obtained for 148 patients (95.5%) with the following responses to surgery: 96.6% of patients experienced successful control of palmar sweating; 69.2% of patients experienced decreased axillary sweating; and 39.8% of patients experienced decreased plantar sweating. At follow-up, 5 patients had palmar sweating (3 patients, <3 months; 1 patient, 10-12 months; 1 patient, 16-18 months). Compensatory hyperhidrosis did not occur in 47 patients (31.7%); it was mild in 92 patients (62.2%), moderate in 7 patients (4.7%), and severe in 2 patients (1.3%). CONCLUSION: In this series, a small-diameter uniportal approach has eliminated intercostal neuralgia. Selecting a T1-T2 sympathotomy yields an excellent palmar response, with a very low severe compensatory hyperhidrosis complication rate. The low failure rate was noted during 18 months of follow-up and suggests that longer follow-up is necessary in these patients. PMID:21803954

The objective of this study was to assess the reduction in quality of life (QoL) caused by the persistence of primary plantar hyperhidrosis (PPH) symptoms and the level of satisfaction in PPH patients after retroperitoneoscopic lumbar sympathectomy (RLS). The efficacy, safety, and procedure of bilateral RLS in both sexes are also described in this study. This is a longitudinal study of consecutive patients who sought specific treatment from a private practitioner for severe PPH as classified on the Hyperhidrosis Disease Severity Scale (HDSS) from October 2005 to October 2014. The patients were asked to report the symptoms of PPH experienced in the immediate preoperative period and to complete a standardized QoL questionnaire developed by de Campos at least 12 months after RLS. Disease outcomes, recurrence of symptoms, and any adverse effects of surgery were evaluated after 30 days and at least 12 months after RLS. Lumbar sympathectomy was performed 116 times in 58 patients; 30 days after surgery, PPH was resolved in all patients. Three patients (5.2%) reported transient thigh neuralgia, and 19 (32.7%) reported transient paresthesia in the lower limbs. There were no reports of retrograde ejaculation. At a minimum of 12 months after RLS, 49 of the 58 patients had fully and correctly answered the follow-up questionnaire and noted a mild (HDSS 2) to moderate (HDSS 3) increase in pre-existing compensatory sweating. One patient had a PPH relapse within 6 months. Improvement in QoL due to the resolution of PPH was reported in 98% of the 49 patients. None of the operations necessitated a change in the laparotomy approach, and none of the patients died. RLS is safe and effective for the treatment of severe PPH in both sexes. There were no reports of retrograde ejaculation after resection of L3 and L4 ganglia. There was a mild to moderate increase in compensatory sweating in about half of the patients, but without any regret or dissatisfaction for having undergone the

INTRODUCTION Level T4 video-assisted thoracoscopic sympathectomy proved superior to T3-T4 treatment for controlling axillary hyperhidrosis at the initial and six-month follow-ups of these patients. OBJECTIVE To compare the results of two levels of sympathectomy (T3-T4 vs. T4) for treating axillary sudoresis over one year of follow-up. METHODS Sixty-four patients with axillary hyperhidrosis were randomized to denervation of T3-T4 or T4 alone and followed prospectively. All patients were examined preoperatively and were followed postoperatively for one year. Axillary hyperhidrosis treatment was evaluated, along with the presence, location, and severity of compensatory hyperhidrosis and self-reported quality of life. RESULTS According to patient reports after one year, all cases of axillary hyperhidrosis were successfully treated by surgery. There were no instances of treatment failure. After six months, compensatory hyperhidrosis was present in 27 patients of the T3-T4 group (87.1%) and in 16 patients of the T4 group (48.5%). After one year, all T3-T4 patients experienced some degree of compensatory hyperhidrosis, compared to only 14 patients in the T4 group (42.4%). In addition, compensatory hyperhidrosis was less severe in the T4 patients (p < 0.01). Quality of life was poor before surgery, and it improved in both groups at six months and one year of follow-up (p = 0.002). There were no cases of mortality, no significant postoperative complications, and no need for conversion to thoracotomy in either group. CONCLUSION Both techniques were effective for treating axillary hyperhidrosis, but the T4 group showed milder compensatory hyperhidrosis and greater patient satisfaction at the one-year follow-up.

To evaluate the benefits of computed tomography (CT)-guided percutaneous sympathicolysis with radiofrequency in patients with primary palmar hyperhidrosis (PPHH) in terms of safety, patient satisfaction, and short- and long-term efficacy. A total of 139 procedures in 108 patients (mean age, 29.89 y ± 10.94), including 50 men and 58 women, with PPHH and therapy-resistance of nonsurgical treatments were retrospectively analyzed. Treatment was performed bilaterally at T2, T3, and T4 levels, reaching 90°C during 8 minutes. Technical success, immediate efficacy, and presence of complications were analyzed. For follow-up, the Hyperhidrosis Disease Severity Scale was used to evaluate the hyperhidrosis before, at one month, and in the long-term through a survey of 42 patients. Patients' satisfaction and complications were also recorded. The technical success rate was 98.56%. The increase in palmar skin temperature was 4.88°C ± 1.85. A total of 85.3% of participants had completely dry hands immediately after treatment. The mean follow-up time was 41.34 months (range, 6-62 mo). One month after treatment, the response rate was 77.38% (P < .001). At long-term follow-up, the response rate was 69.04% (P < .001). Two major complications were observed (1.8%), 52.38% of patients were satisfied, and 59.52% of patients presented compensatory hyperhidrosis at long-term follow-up. Percutaneous CT-guided sympathicolysis is a safe and effective technique for the treatment of PPHH and can be considered as a second choice in patients in whom other nonsurgical therapeutic options have failed, despite the compensatory hyperhidrosis rates.

Hyperhidrosis is an excessive sweating disorder affecting quality of life. Endoscopic thoracic sympathectomy (ETS), introduced by Kux in 1951, is currently the gold standard surgical treatment for primary hyperhidrosis. 75% of patients with primary hyperhidrosis have seen improvement in quality of life within 30 days after surgery. Compensatory hyperhidrosis and pneumothorax (up to 75%) have been reported in patients after surgery. This study evaluates the functional status, self- esteem, compensatory hyperhidrosis and quality of life among patient with primary hyperhidrosis before and after undergoing ETS. Fifty (n=50) patients between the ages 18 to 30, with primary hyperhidrosis were recruited. Patients answered the quality of life questionnaire and Rosenberg self-esteem questionnaire prior to surgery and 30 days post surgery on follow up. Any post-operative complications were documented. Telephone interviews were held for patients who were unable to attend the clinics for follow-up. Forty six patients (92%) had symptomatic relieve within 30 days of surgery. The incidence of compensatory sweating was 78% (39 patients), with 6 patients developing severe hyperhidrosis. Two patients who did not experience symptomatic relieve, developed compensatory hyperhidrosis. Pneumothorax was documented in 8 patients (16%), with 6 patients requiring chest tubes. Significant improvement in quality of life and self-esteem was seen among patients after surgery. ETS has shown to significantly improve the quality of life and self-esteem of patients with primary hyperhidrosis within 30 days of surgery. However, the rate of compensatory hyperhidrosis still remains high (78%) which requires a long term evaluation.

Hyperhidrosis may affect nearly 3% of the population, and thoracic/lumbar sympathectomy has been highly effective. Compensatory hyperhidrosis is a risk associated with surgical procedures, and its treatment is both complex and not well defined. Treatment of primary hyperhidrosis with oxybutynin has yielded positive results; however, its use in compensatory hyperhidrosis (CH) has not been described. Twenty-one patients (11 female patients) received oxybutynin for severe CH at a median of 5 years after sympathectomy. Patients were evaluated to determine quality of life before starting oxybutynin and 6 weeks afterward; they assigned grades to determine improvement after 6 weeks and at their last consult visit for each site at which they complained of symptoms. Six and 15 patients underwent operation for axillary hyperhidrosis and palmar hyperhidrosis, respectively. Median follow-up time with oxybutynin was 377 days (49-1,831 days). Most common CH sites were the back (n=8) and abdomen (n=5). After 6 weeks, the quality of life improved in 71.4% of patients. Five patients stopped treatment: 2 because of unbearable dry mouth, 1 because of absence of pharmacologic response, 1 because of excessive somnolence, and 1 because of probable tachyphylaxis. At the last visit, 71.4% of patients presented with moderate to major improvement at the main sites at which sweating was noted. More than 70% of patients presented with improved overall quality of life and improvement at the most prominent site of compensatory sweating. Long-term treatment was ineffective in less than 25% of patients, primarily because of the side effects of dry mouth and somnolence. Oxybutynin appears to be effective in treating bothersome CH.

Introduction Hyperhidrosis is excessive sweating beyond the needs of thermoregulation. It is disease which mostly affects young people, often carrying a considerable amount of socio-economic implications. Thoracic sympathectomy is now considered to be the "gold standard" in the treatment of idiopathic hyperhidrosis of hands and armpits. Aim Assessment of early effectiveness of thoracic sympathectomy using skin resistance measurements performed before surgery and in the postoperative period. Material and methods A group of 20 patients with idiopathic excessive sweating of hands and the armpit was enrolled in the study. Patients underwent two-stage thoracic sympathectomy with resection of Th2-Th4 ganglions. The skin resistance measurements were made at six previously designated points on the day of surgery and the first day after the operation. Results In all operated patients we obtained complete remission of symptoms on the first day after the surgery. Inhibition of sweating was confirmed using the standard starch iodine (Minor) test. At all measurement points we obtained a statistically significant increase of skin resistance, assuming p < 0.05. To check whether there is a statistically significant difference in the results before and after surgery we used sequence pairs Wilcoxon test. Conclusions Thoracic sympathectomy is an effective curative treatment for primary hyperhidrosis of hands and armpits. Statistically significant increase of skin resistance in all cases is a good method of assessing the effectiveness of the above surgery in the early postoperative period. PMID:23256019

The purpose of this study was to evaluate the results, complications, and degree of satisfaction among patients who underwent a CT-guided percutaneous puncture thoracic sympathetic blockade. A total of 186 patients underwent CT-guided thoracic sympathetic blockade based on case histories and a prospective pre- and postoperative questionnaire survey. The study sample was composed of 93 patients with an age range from 18 to 34years and a diagnosis with primary palmar hyperhidrosis (severe in some patients). Percutaneous puncture thoracic sympathetic blockade guided by CT was performed under local anesthesia in all patients. Heart rate (HR), non-invasive blood pressure (NIBP), arterial oxygen saturation (SPO 2 ), perfusion index (PI), and palmar temperature (T) were monitored before and after treatment. Follow-up included a questionnaire on life quality and degree of satisfaction. Ten minutes after treatment, the SPO 2 , PI, and temperature all raised remarkably ([92.75±2.02]% vs. [98.85±1.09]%, [1.55±0.69]% vs. [8.60±0.94]%, [30.95±1.27]°C vs. [35.75±0.55]°C, respectively, P<0.001). The therapeutic success rate was 96.7%. No operative mortality was recorded. No complications were observed, except transient bradycardia in one patient and transient injection site pain in 25 patients. Of the 89 patients who were monitored over a period of 6-12months through follow-up interviews and questionnaires, 46% developed compensatory hyperhidrosis, 87.6% reported improvement in their quality of life. CT-guided percutaneous puncture thoracic sympathetic blockade is a safe, effective, and minimally invasive technique for the treatment of palmar hyperhidrosis. Despite the high rate of compensatory hyperhidrosis, it produces a high rate of patient satisfaction. Copyright © 2016 Elsevier Ltd. All rights reserved.

Botulinum toxin is a safe and effective therapy for palmar hyperhidrosis, but the associated pain from injections limits the usefulness of this method of treatment. To evaluate the efficacy of Eutectic Mixture of Local Anesthetics (EMLA) cream versus ice application in alleviation of pain during botulinum toxin injections for palmar hyperhidrosis. In this prospective study, 23 patients underwent palm Botox injections to treat their excessive sweating. In each patient, EMLA cream was applied to one palm and ice was applied directly before the injections in the other palm. Pain was evaluated using a Visual Analog Scale. Statistically, there was a significant difference in pain control between EMLA cream group and ice application group ( p <0.05). The average pain score on the hands where EMLA cream was applied was 8.9 (SD=0.81), whereas it was 4.8 (±0.9) in the ice group. In this study, the successful use of ice application in reducing pain by 40% in comparison to EMLA cream during Botox toxin injection for palmar hyperhidrosis is demonstrated.

'Rusters'. The corrosive action of palmar sweat: II. Physical and chemical factors in palmar hyperhidrosis.

PubMed

Jensen, O; Nielsen, E

1979-01-01

When measuring sweating rates, close correspondence was found with the clinical estimation of hyperhidrosis. Corrosion was seen to increase with increasing sweat rates, reaching its maximum after an assumed rise in the actual sodium chloride concentration on the skin surface due to evaporation of water. The findings confirm that hyperhidrosis is of primary importance in the constitution of a 'ruster', and are also in good agreement with experimental reports. The small variations in palmar skin pH had no influence on the degree of corrosion; nor had the character of the metal surface. Of the two types of metal studied. corrosion was much more severe on the type having the lowest concentration of copper, thus confirming that increasing copper concentrations have a positive effect in reducing corrosion rates. At 50--60% relative humidity (RH) corrosion increased as time elapsed, whereas at 40% RH no corrosion developed on a sweat-contaminated plate. When exposed to 75% RH, metal samples became severely corroded in the course of a few days. Protective methods for the avoidance of rust are mentioned, with special emphasis on frequent handwashing.

Hyperhidrosis continues to be undertreated in our view, despite its propensity to considerably impair quality of life. We shall break down therapeutic approaches to hyperhidrosis into several steps: (a) determine the physiological causes of excess sweating; (b) establish the type of hyperhidrosis involved and screen for causes of secondary hyperhidrosis before diagnosing essential hyperhidrosis; (c) evaluate the severity of the hyperhidrosis by means of a validated scale (HDSS score), Minor's starch-iodine test or gravimetric analysis; (d) select one of the medical therapies currently available, i.e. topical therapy (antiperspirants, iontophoresis or botulinum toxin injection), systemic therapy (oxybutynin) or surgery (thoracic sympathectomy).

Hyperhidrosis is a condition in which the production of sweat is abnormally increased. No objective criteria for the diagnosis of hyperhidrosis exist, mainly because reference intervals for normal physiological sweat production at rest are unknown. The main objective of this study was to establish reference intervals for normal physiological axillary and palmar sweat production. Gravimetric testing was performed in 75 healthy control subjects. Subsequently, these results were compared with findings in a cohort of patients with hyperhidrosis and with the results derived from a review of data on hyperhidrosis published between 1980 and 2013. Approximately 90% of the controls had axillary and palmar sweat production rates of below 100 mg/5 min. In all except one of the axillary and palmar hyperhidrosis studies reviewed, average sweat production exceeded 100 mg/5 min. A sweat production rate of 100 mg/5 min as measured by gravimetric testing may be a reasonable cut-off value for distinguishing axillary and palmar hyperhidrosis from normal physiological sweat production. © 2015 The International Society of Dermatology.

Oxybutynin for treating hyperhidrosis in children has been evaluated only in short-term studies. We aimed to investigate the long-term effects of oxybutynin in treating children with palmar and plantar hyperhidrosis who had not undergone surgery and who were monitored for at least 6 months (median 19.6 mos). A cohort of 97 patients was evaluated retrospectively, with particular attention to 59 children (ages 4-14 yrs) who were treated for longer than 6 months. Their quality of life (QOL) was evaluated using a validated clinical questionnaire before and after 6 weeks of pharmacologic therapy. A self-assessment of hyperhidrosis was performed after 6 weeks and after the last consultation. By their final office visit, more than 91% of the children with hyperhidrosis treated with oxybutynin experienced moderate or great improvement in their level of sweating and 94.9% experienced improvement in QOL. More than 90% of children reported improvement of hyperhidrosis at other sites. Dry mouth was the most common side effect. Oxybutynin appears to be an effective treatment option for children with hyperhidrosis, and positive results are maintained over the long term (median 19.6 mos). © 2014 Wiley Periodicals, Inc.

Intradermal injections of botulinum toxin are effective but transitory in primary palmar hyperhidrosis. These injections are repeated when the symptoms recur. We do not know how the duration of efficacy changes when injections are repeated. In this retrospective study, we aimed to investigate the change in the duration of efficacy of botulinum toxin A (Dysport, Ipsen, Boulogne-Billancourt, France) with the repetition of injections in patients with primary palmar hyperhidrosis. From May 2001 to April 2012, 28 patients were treated with a dose of 250 U of botulinum toxin A per palm. We compared the duration of efficacy of the first and last toxin injections. The median duration of efficacy was 7 months for the first injection and 9.5 months for the last, the difference being statistically significant (P = .0002). Study limitations include a relatively small number of patients treated at a single center and evaluated retrospectively. To our knowledge, this study is the first to report a significant increase in the duration of efficacy of botulinum toxin A injections with the repetition of injections in patients with primary palmar hyperhidrosis. The reasons for this effect may be linked to the mechanism of action of botulinum toxin, and may improve our understanding of its pharmacologic effects.

The aim of this work was to assess the prevalence of palmar and axillary hyperhidrosis among young Polish adults. Additionally, this work aimed at comparing the subjective and objective (gravimetric) method of hyperhidrosis assessment. Healthy medical students, volunteering to take part in this study, were included. The participants filled out a questionnaire assessing the occurrence and subjective intensity of hyperhidrosis in different areas of the body. Additionally, the students were subjected to gravimetric assessment in four localizations: the face, palms, axillae and abdomino-lumbar area. Two hundred and fifty-three students (102 males and 151 females, mean age 24.3 ± 3.21 years) were included in the study. Forty-two (16.7%) participants declared that they suffer from hyperhidrosis. Out of the 42 students declaring any type of hyperhidrosis, only 20 (47.6%) exceeded the gravimetric reference values. From among the students that exceeded the normative values for palmar hyperhidrosis, only 10 (55.6%) were aware of their hyperhidrosis. In the group of students that exceeded the normative values for axillary hyperhidrosis, 16 (39%) were aware of their hyperhidrosis. Subjectively declared hyperhidrosis incidence may significantly exceed the real-life occurrence of this disease. Basing studies solely on data gathered from questionnaires, may lead to false results. It is imperative, when assessing patients suffering from hyperhidrosis, to use both objective and subjective methods of evaluation. © 2013 Japanese Dermatological Association.

Plantar hyperhidrosis, excessive sweating on the soles of feet, can have a significant impact on patients' quality of life and emotional well-being. Hyperhidrosis is divided into primary and secondary categories, depending on the cause of the sweating, with plantar hyperhidrosis typically being primary and idiopathic. There is an overall increased risk of cutaneous infection in the presence of hyperhidrosis, including fungal, bacterial, and viral infections. This article discusses a range of treatment options including topical aluminum chloride, iontophoresis, injectable botulinum toxin A, glycopyrrolate, oxybutynin, laser, and endoscopic lumbar sympathectomy. Lifestyle changes regarding hygiene, shoe gear, insoles, and socks are also discussed. Copyright © 2016 Elsevier Inc. All rights reserved.

Focal hyperhidrosis can severely affect quality of life. So far, knowledge on the effect of systemic therapy of focal hyperhidrosis is limited. To assess the efficacy and safety of methantheline bromide (MB) in the treatment of axillary and palmar-axillary hyperhidrosis. A multicenter controlled randomized double-blind clinical trial was conducted in patients with axillary or palmar-axillary hyperhidrosis defined by a sweat production >50 mg/5 min. Patients received 3 × 50 mg MB daily or placebo over a period of 28 ± 1 days. Main outcome criterion was the reduction of sweat as measured by gravimetry on day 28 ± 1. Quality of life was assessed by Dermatology Life Quality Index (DLQI) and Hyperhidrosis Disease Severity Score (HDSS). A total of 339 patients were randomly assigned to receive MB or placebo. On day 28 ± 1, the mean axillary sweat production was 99 mg for MB and 130 mg for placebo compared with 168 mg and 161 mg respectively at baseline (P = 0.004). Patient's HDSS score decreased in the MB group from 3.2 to 2.4 compared with 3.2 to 2.7 for placebo (P = 0.002). Similar results could be obtained for the DLQI with 9.7 for MB and 12.2 for placebo, which decreased from 16.4 or 17 respectively (P = 0.003). Tolerability was good for both groups. The most frequent adverse event was dry mouth. Fifty milligrams methantheline bromide three times a day is an effective and safe treatment of axillary hyperhidrosis. © 2012 The Authors.

Thoracoscopic sympathectomy (TS) is an effective treatment for hyperhidrosis. Various surgical approaches are described in the literature. We describe the technique of thoracoscopic excision of the sympathetic chain done exclusively in children younger than 13 years. All patients younger than 13 years who underwent TS from 2006 at a single institution were prospectively identified and fully evaluated with emphasis on demographic data, age, surgical management, complications and follow-up. All patients were contacted again at the end of 2009 to complete a follow-up questionnaire. Twelve patients underwent TS between 2006 and 2009. Age ranged from 6 to 13 years. This involved T2-T3 excision for nine patients with isolated palmar hyperhidrosis, and T2-T3-T4 excision for three with additional axillary hyperhidrosis. Six underwent bilateral TS at the same session and six underwent unilateral TS for the dominant side. Four of them had their contralateral operation performed 2-3 months later. Dry limbs were immediately achieved in all patients. Compensatory sweating (CS) was noted in eight patients. Complications included transient ptosis in two and mild recurrence in one. Thoracoscopic excision of the sympathetic chain is a simple and safe procedure that relieves hyperhidrosis in all cases and significantly improves the quality of life.

The present paper aims to study the prevalence of the various manifestations of hyperhidrosis in patients who sought treatment in a specialized ambulatory in the state of São Paulo. Opposite to previous studies, this paper studies the different combinations of sweating sites, not being restricted to the main complaint site of the patients, but taking into consideration secondary complaints patients may present. This was a retrospective approach of a database containing more than 1200 patients in which were mapped: combination of sweating sites, age of onset, age spectrum, mean age, body mass index and gender of patients. Patients were categorized into four groups based on their main sweating site - palmar, plantar, axillary and facial. We concluded that hyperhidrosis appears frequently in more than one site, being the main complaint that affects the most patients palmar hyperhidrosis, which appears early in the patients during adolescence. When there are two sites of sweating, the most frequent combination is palmar + plantar, and when there are three sites of sweating the most frequent combinations are palmar + plantar + axillary and axillary + palmar + plantar. This research has casuistics limited to a single care service for patients with hyperhidrosis. It is necessary to keep in mind that the disease manifests itself mainly in more than one location, with different intensities in each of the patients, generating a significant impairment of their quality of life.

Evaluation of pain and degree of satisfaction in patients undergoing ultrasound-assisted peripheral regional block for the treatment of idiopathic palmar hyperhidrosis with botulinum toxin. A descriptive, observational study of patients with palmar hyperhidrosis treated with botulinum toxin A, who underwent ultrasound-guided peripheral regional block of the median and ulnar nerves with 3 ml of mepivacaine 1% in each one. The radial nerve block was injected in the anatomical snuffbox. After establishing blocking, the dermatologist performed a mapping and injected around 100 IU of botulinum toxin across the whole palm. The pain experienced during the injection of botulinum toxin was evaluated by verbal numerical scale (from 0 to 10), along with the degree of satisfaction with the anesthetic technique, and the post-anesthetic complications. A total of 40 patients were enrolled in the study, 11 men and 29 women with no significant differences. The pain intensity assessed with verbal numerical scale was 1.03 (standard deviation of 1.37). No patients had a value greater than 5. The degree of patient satisfaction with the anesthetic technique was very good for 85% of the patients, and good for 7.5%. There were no complications related to type of anesthesia. The ultrasound-assisted peripheral regional block could be a simple, effective and safe technique for patients undergoing palmar injection of botulinum toxin. Pain intensity was very low, and it provided a very good level of satisfaction in most patients. Copyright © 2013 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

Hyperhidrosis is a condition characterized by generalized or localized hyperfunction of the eccrine sweat glands with a deep negative impact on patient's quality of life. To evaluate the efficacy and the safety of Botulin Toxin A (BTX-A) intradermal injection in the treatment of primary axillary and palmar hyperhidrosis, investigating symptoms-free period, and the subjective improving of quality life. 50 consecutive patients with primary hyperhidrosis were evaluated detecting age, gender, hyperhidrosis onset period, disease duration and years of treatment with BTX-A, Minor's iodine test, Hyperhidrosis Disease Severity Scale (HDSS), Dermatology Life Quality Index (DLQI). The treatment is significantly effective both for axillae and palms: the majority of the patients improved their HDSS and Minor's scores from a value of 4 in the two tests, to values of 1 (HDSS) and 0 (Minor test). Patients reported a duration of symptoms relief from 4 to 12 months, with a mean of 5.68 months; specifically, we have observed that the axillary group experienced a longer symptoms-free period (mean RFS 7.2 months) than the palmar group (mean: RFS 4.27 months). Authors suggest that BTX-A is a safe, easy, and fast procedure for the treatment of primary axillary and palmar hyperhidrosis.

A literature search was conducted using various databases and search criteria. The literature reports the use of conservative, medical and surgical treatment modalities for the management of plantar hyperhidrosis. However, long-term follow-up data are rare and some treatment modalities currently available are not fully understood. There is a considerable dearth in the literature on the management of plantar hyperhidrosis. Further study in larger populations with longer follow-up times is critical to access the long-term effects of treatment. Nonetheless, iontophoresis, botulinum toxin injection and lumbar sympathectomy are promising treatment modalities for this disorder.

Purpose: To investigate the association between intraoperative palm temperature change and the curative effect of sympathicotomy. Methods: 49 patients with palmar hyperhidrosis were treated with bilateral endoscopic sympathicotomy. Ipsilateral palm temperature was monitored before and at 3–5 min increments after the sympathetic trunk was transected. The maximum temperature elevation (Tmax) was calculated and used to evaluate the effect on postoperative cure rates. Results: Forty-nine patients underwent 98 sympathicotomies. There were 77 T4 sympathicotomies, 15 T4 + T5 sympathicotomies, and six T3 sympathicotomies due to pleural adhesions or neurovascular proximity. The Tmax was ≤1°C in 49 (50.0%), 1–1.5°C in 17 (17.3%), and >1.5°C in 32 (32.7%) palms. Ninety-two palms of 46 patients were followed with complete efficacy, and three patients were lost to follow up. Cure was achieved in 86 palms (93.4%). Of the 71 palms which underwent T4 sympathicotomy, cure was achieved in 67 palms (94.3%). In those palms which did not achieve cure, the Tmax was less than 1°C in each case, while in palms with a Tmax ≤1°C, 32 of 36 (88.9%) were cured. Conclusion: There is an association between intraoperative palmar temperature change and curative effect. However, palmar temperature change cannot be used to predict cure or guide surgical approach.

to compare the intensity of reflex sweating with the degree of anxiety and its interference in the quality of life of patients undergoing Thoracoscopic (VATS) sympathectomy in the pre- and postoperative period. we evaluated 54 patients with a mean age of 26 years (16-49 years) undergoing sympathectomy in the R3-R4 level. We applied two questionnaires at three different times: "Quality of life in patients with primary hyperhidrosis" and "Scale for anxiety and depression". of the patients studied, 93% showed significant improvement in quality of life 30 days after surgery, the effects remaining after six months. There were no postoperative complications. The patient's level of anxiety is highly correlated with the intensity of reflex sweating after 30 and 180 days. Thoracoscopic sympathectomy improves quality of life of patients with primary hyperhidrosis, even with the emergence of reflex sweating. Anxiety directly relates to the intensity of reflex sweating, without compromising the degree of patient satisfaction. avaliar a intensidade de sudorese reflexa com o grau de ansiedade e sua interferência na qualidade de vida de indivíduos submetidos à simpatectomia por videotoracoscopia nos períodos pré e pós-operatório. foram avaliados 54 pacientes com média de idade de 26 anos (16 a 49 anos), submetidos à simpatectomia em nível R3-R4. Dois questionários foram aplicados em três momentos diferentes: "Qualidade de vida em pacientes com hiperidrose primária e "Escala para ansiedade e depressão". dos pacientes estudados, 93% mostrou melhora significativa na qualidade de vida após 30 dias da cirurgia, com os efeitos remanescentes após seis meses. Não houve complicações pós-operatórias. A análise mostrou que o nível de ansiedade do paciente é altamente correlacionado com a intensidade da sudorese reflexa após 30 e 180 dias. a simpatectomia torácica por videotoracoscopia melhora a qualidade de vida de pacientes com hiperidrose primária, mesmo com o

Objective assessment of the effect of botulinum toxin A (BT) treatment in primary palmar hyperhidrosis (PH) is attempted by different methods. We decided to use for this purpose sympathetic skin responses evoked by train of stimuli (TSSR). Twenty patients with severe PH (five female, median age 24, range 18-36) were examined regularly over 3 months after receiving 50 UI BT in each palm. TSSR were recorded from the palms after sensory stimulation by a train of three supramaximal electric pulses 3 millisecond apart. Results were compared to longitudinally studied TSSR of 20 healthy sex- and age-matched control subjects. All hyperhidrosis patients reported excellent improvement. TSSR amplitudes decreased at week 1 (mean 54% range 48%-67%) and over the following months in a clinically significant trend (slope R=-.82, P<.0001). TSSR in controls changed insignificantly (±13% from the baseline). The difference between patients and controls was highly significant at any time point (P<.001). This study suggests that TSSR may help in assessment of treatments in PH. It confirms objectively the efficacy of BT in PH. © 2016 John Wiley & Sons Ltd.

Microwave Treatment for Axillary Hyperhidrosis and Bromhidrosis.

Axillary hyperhidrosis (AH) and bromhidrosis are common causes of consultation in dermatology. Currently, the most widely prescribed treatment for AH is botulinum toxin, a very effective but temporary option; it is totally ineffective in bromhidrosis. Sympathectomy is an increasingly infrequent choice of treatment due to the high incidence of compensatory hyperhidrosis. We describe the treatment of AH and bromhidrosis with a novel microwave device that can fibrose eccrine and apocrine glands, achieving possibly permanent results. The procedure should preferably be performed under tumescent anesthesia. Side effects, principally local inflammation, are transient. Clinical effectiveness and safety, supported by recently published studies, position this technique as a first-choice option both for hyperhidrosis and for bromhidrosis. Copyright © 2017 AEDV.

Hyperhidrosis is a disorder of perspiration in excess of the body's physiologic need and significantly impacts one's occupational, physical, emotional, and social life. The purpose of our study was to investigate the characteristics of primary hyperhidrosis in 255 patients at Ajou University Hospital Hyperhidrosis Center from March 2006, to February 2008. Information collected from the medical records was: sex, sites of hyperhidrosis, age at visit, age of onset, aggravating factors, hyperhidrosis disease severity scale (HDSS) rank, family history, occupation, and past treatment. A total of 255 patient records were reviewed; 57.6% were male. Patients with a family history (34.1%) showed a lower age of onset (13.21±5.80 yr vs. 16.04±9.83 yr in those without family history); 16.5% had previous treatment, most commonly oriental medicine. Palmar and plantar sites were the most commonly affected, and 87.9% of patients felt their sweating was intolerable and always interfered with their daily activities. Our study provides some original information on the Korean primary hyperhidrosis population. Patients who have a family history show signs of disease in early age than those without family history.

The best way to evaluate the impact of primary hyperhidrosis on quality of life (QL) is through specific questionnaires, avoiding generic models that do not appropriately evaluate individuals. QL improves significantly in the short term after sympathectomy. In the longer term, a sustained and stable improvement is seen, although there is a small decline in the numbers; after 5 and even at 10 years of follow-up it shows virtually the same numerical distribution. Compensatory hyperhidrosis is a major side effect and the main aggravating factor in postoperative QL, requiring attention to its management and prevention. Copyright © 2016 Elsevier Inc.

Video thoracoscopic sympathectomy is the recommended surgical treatment for primary hyperhidrosis and has a high success rate. Despite this high success rate, some patients are unresponsive and eventually need a resympathectomy. Few studies have previously analysed exclusively the results of these resympathectomies in patients with primary hyperhidrosis. None of the studies have objectively evaluated the degree of response to surgery or the improvement in quality of life after resympathectomies. This is a retrospective study, evaluating 15 patients from an initial group of 2300 patients who underwent resympathectomy after failure of the primary surgical treatment. We evaluated sympathectomy levels of resection, technical difficulties, surgical complications preoperative quality of life, response to treatment and quality-of-life improvement 30 days after each surgery. Regarding gender, 11 (73.3%) patients were women. The average age was 23.2 with SD of 5.17 years, and the mean body mass index was 20.9 (SD 2.12). Ten patients had major complaints about their hands (66%) and 5 (33%) patients about their forearms. A high degree of response to sympathectomy occurred in 73% of patients. In 11 of these patients, the improvement in quality of life was considered high, 3 showed a mild improvement and 1 did not improve. No major complications occurred; the presence of adhesions was reported in 11 patients and pleural drainage was necessary in 4 patients. Resympathectomy is an effective procedure, and it improves the quality of life in patients with primary hyperhidrosis who failed after the first surgery. © The Author 2017.

Summary Hyperhidrosis is a potential cause of severe physical and psychological distress, interfering in activities of daily living. Over the past 100 years, advances have been made regarding the treatment of this debilitating condition with some success. Surgical treatment with sympathectomy was successfully performed for hyperhidrosis in the early part of the 20th century, with various modifications of the technique over the past 100 years. Topical aluminium salt antiperspirants, anticholinergic medications, iontophoresis and botulinum toxin introduced less invasive ways to manage this condition. This historical review will enable dermatologists and non-dermatologists to manage this distressing condition. PMID:25057361

Botulinum Toxin Treatment of Autonomic Disorders: Focal Hyperhidrosis and Sialorrhea.

PubMed

Hosp, Christine; Naumann, Markus K; Hamm, Henning

2016-02-01

Primary focal hyperhidrosis is a common autonomic disorder that significantly impacts quality of life. It is characterized by excessive sweating confined to circumscribed areas, such as the axillae, palms, soles, and face. Less frequent types of focal hyperhidrosis secondary to underlying causes include gustatory sweating in Frey's syndrome and compensatory sweating in Ross' syndrome and after sympathectomy. Approval of onabotulinumtoxinA for severe primary axillary hyperhidrosis in 2004 has revolutionized the treatment of this indication. Meanwhile further type A botulinum neurotoxins like abobotulinumtoxinA and incobotulinumtoxinA, as well as the type B botulinum neurotoxin rimabotulinumtoxinB are successfully used off-label for axillary and various other types of focal hyperhidrosis. For unexplained reasons, the duration of effect differs considerably at different sites. Beside hyperhidrosis, botulinum neurotoxin is also highly valued for the treatment of sialorrhea affecting patients with Parkinson's disease, cerebral palsy, amyotrophic lateral sclerosis, motor neuron disease, and other neurologic conditions. With correct dosing and application, side effects are manageable and transient. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Hyperhidrosis in Iranian Traditional Medicine.

Excessive sweating is a medical condition in which a person sweats much more than needed. The medical name of this disorder is hyperhidrosis known as a common dermal problem that affects people of all ages and leads to negative impact on the quality of life. During the last decades, several studies have shown that in many cases of hyperhidrosis there is no evidence of systemic disease. Therefore, most treatments are temporary and symptomatic therapy. According to Iranian traditional medicine (ITM), different approaches are mentioned for hyperhidrosis. This study has reviewed ITM textbooks, such as "Canon of Medicine and Exir-e-azam" as well as scientific references and databases of modern medicine (ISI, PubMed, etc.) with specific keywords. Contents and related concepts were classified and results prepared. In modern medicine, hyperhidrosis has been defined as an abnormal excessive sweating, which is either primary (idiopathic) or secondary to other systemic diseases such as hyperthyroidism, neurological condition or heart disease. Current modalities for treatment are topical anti-perspiration, iontophoresis, Botox injection (Botulinum toxin type A) and eventually thoracic sympathectomy as the last therapeutic modalities. From the viewpoint of the Iranian traditional medicine as a holistic doctrine, hyperhidrosis etiologies include overfilled and repletion of body due to the accumulation of humors, excessive intake of food, excessive dilated skin pores, vigorous exercise, or physical activity. Therefore, therapeutic plan for hyperhidrosis was based on its cause, which includes reduction in the amount of food, increasing physical activity, purging the body from the excess humors and adjustment in temperament. Hyperhidrosis is not an important or dangerous disorder; however, due to the negative impact on quality of life and failure to achieve perfect answer in modern medicine treatments it seems that the recommendations of Iranian traditional medicine will be helpful

Transareolar single-port needlescopic thoracic sympathectomy under intravenous anesthesia without intubation has rarely been attempted in managing primary palmar hyperhidrosis (PPH). The objective of this study is to evaluate the feasibility and safety of this minimally invasive technique. From May 2012 to May 2015, 168 male patients with severe PPH underwent single-port endoscopic thoracic sympathectomy (ETS) and were randomly allocated to groups A or B. Patients in group A underwent nonintubated transareolar ETS with a 2-mm needle endoscope, while those in group B underwent intubated transaxillary ETS with a 5-mm thoracoscope. All procedures were performed successfully. The palms of all patients became dry and warm immediately after surgery. The mean resuscitation time was significantly shorter in nonintubated patients than in intubated patients. Postoperative sore throat occurred in 4 patients in group A and in 32 patients in group B (P < .01). The mean incision length was significantly shorter in group A than in group B. The mean postoperative pain scores were markedly higher in group B than in group A. The mean cost of anesthesia was considerably lower in nonintubated patients than in intubated patients. The mean cosmetic scores were higher in group A than in group B (P < .01). Nonintubated transareolar single-port ETS with a needle endoscope is a safe, effective, and minimally invasive therapeutic procedure, which allows a smaller incision with less pain and excellent cosmetic results. This novel procedure can be performed in a routine clinical practice for male patients with severe PPH.

A 19 year-old boy who developed a right Horner's syndrome after a bilateral sympathectomy as a treatment for palmoplantar hyperhidrosis. Horner's syndrome is defined by the occurrence of miosis, ptosis and enophthalmos as a result of involvement of sympathetic innervation. This is quite rare, but identification is very important because it may also be an ominous sign secondary to a neoplasm, neurological diseases, or surgery of the sympathetic chain, as in our case.

Facial hyperhidrosis can lead to serious emotional distress. Video-assisted thoracic sympathectomy resolves symptoms effectively, though it may be associated with compensatory hyperhidrosis, which may be more common in patients undergoing resection of the second thoracic ganglion. Oxybutynin has been used as a pharmacological approach to facial hyperhidrosis but the long-term results of this treatment are unclear. To evaluate the use of low oxybutynin doses in facial hyperhidrosis patients for at least six months. 61 patients were monitored for over six months and assessed according to the following variables: impact of hyperhidrosis on quality of life (QOL) before treatment and after six weeks, evolution of facial hyperhidrosis after six weeks and at the last consultation, complaints of dry mouth after six weeks and on last return visit, and improvement at other hyperhidrosis sites. Patients were monitored for 6 to 61 months (median=17 months). Thirty-six (59%) were female. Age ranged from 17-74 (median:45). Pre-treatment QOL was poor/very poor in 96.72%. After six weeks, 100% of patients improved QOL. Comparing results after six weeks and on the last visit, 91.8% of patients maintained the same category of improvement in facial hyperhidrosis, 3.3% worsened and 4.9% improved. Dry mouth complaints were common but not consistent throughout treatment. More than 90% of patients presented moderate/great improvement at other hyperhidrosis sites. Patients who had a good initial response to treatment maintained a good response long-term, did not display tachiphylaxis and experienced improvement on other hyperhidrosis sites.

Primary hyperhidrosis, although extensively documented in adults, typically has onset that dates back to early childhood. It is an unpleasant and socially disabling problem for the affected child, but little attention has been paid to the disease in adolescents. The objective of the current study was to evaluate the effectiveness of botulinum toxin type A (BTXA) in adolescents with primary palmar and axillary hyperhidrosis and to determine its effect on quality of life and social isolation. Thirty-five individuals (17 girls, 18 boys) with moderate to severe palmar and axillary hyperhidrosis were treated with BTXA (onabotulinum). Patients were examined at baseline and 6 months after treatment. The Hyperhidrosis Disease Severity Scale (HDSS) was used to evaluate disease severity and the Children's Dermatology Life Quality Index (CDLQI) was used to assess quality of life. The University of California at Los Angeles loneliness scale (UCLA version 3) was used to assess personal perception of loneliness and social isolation. The median age of the participants was 14 years, and 48.6% were female. Twenty-one had palmar hyperhidrosis, and 14 had axillary hyperhidrosis. Total CDLQI and social isolation scores decreased significantly after treatment with BTXA (both p < 0.001). There was a significant difference between pre- and post-treatment levels of severity of hyperhidrosis. No statistically significant difference was documented for CDLQI and UCLA scores between boys and girls. Treatment of hyperhidrosis with BTXA resulted in improvement in quality of life, social skills, and activities. © 2014 Wiley Periodicals, Inc.

The aim of the study was to evaluate the sympathectomy procedures for primary hyperhidrosis in terms of complications and effectiveness. From January 2010 to September 2012 we performed 130 sympathectomies in 65 patients, 27 males (42%) and 38 females (58%). Electrocoagulation was used in 20 procedures (15%), ultrasonic scalpel in 54 (42%), and radiofrequency dissector in 56 (43%). Seven patients (11%) underwent bilateral sympathectomy in the same surgical session, while in 58 (89%) the right surgical approach was delayed 30 days from the first procedure. We noticed 12 complications (9%): (a) chest pain in 6 patients (4 with electrocoagulation, 1 with ultrasonic scalpel, and 1 with radiofrequency dissector), which disappeared in 20 ± 1 day; (b) paresthesias in 3 electrocoagulation patients, was solved in 23 ± 5 days; (c) bradycardia in 1 ultrasonic patient, normalized in 4th postoperative hour; (d) unilateral relapse in 2 electrocoagulation patients after the second side approach, positively treated in 1 patient by resurgery in video-assisted thoracoscopy (VAT). The quality-adjusted life year and the quality of life evaluation revealed a statistically significant improvement (p = 0.02) in excessive sweating and general satisfaction after surgery, with Ultracision and LigaSure showing better findings than electrocoagulation. The latest generation devices offered greater efficacy in the treatment of hyperhidrosis, minimizing complications and facilitating the resumption of normal work and social activity of patients.

Primary hyperhidrosis is a disorder of excessive, bilateral and relatively symmetrical sweating occurring in the palms, soles and axillae regions without obvious etiology. There have been some reports of the epidemiology of primary hyperhidrosis abroad so far, but there has never been any research performed in Japan. We performed a questionnaire survey for people aged 5-64 years who agreed with the purpose of this study at 20 companies or schools, and received 5807 valid responses. From this survey, each prevalence could broken down into 5.33% for primary palm hyperhidrosis, 2.79% for primary plantar hyperhidrosis, 5.75% for primary axillae hyperhidrosis and 4.7% for primary head hyperhidrosis. Patients with severe symptoms were estimated to be approximately 616,000 for primary palmar hyperhidrosis and 2,239,000 for primary axillae hyperhidrosis in Japan. These findings reveal that many patients feel a decreased quality of life because of symptoms of hyperhidrosis every day. However, only 6.2% of the patients had visited medical institutions. Moreover, few patients take appropriate treatment even after visiting the hospital. © 2013 Japanese Dermatological Association.

Thoracoscopic sympathectomy increases efferent cardiac vagal activity and baroreceptor sensitivity.

Thoracoscopic sympathectomy at levels T2 or T2-T3 is a treatment for focal hyperhidrosis and facial blushing. These levels of the sympathetic trunk innervate the heart, and consequently, the procedure is reported to change the heart rate variability due to changes in efferent cardiac autonomic activity. Our objective was to investigate the effects of thoracoscopic sympathectomy on global autonomic control, including baroreceptor sensitivity. Eight patients (6 F, median age 28 years [range 20-58 years]) were exposed to the tilt-table test and cardiopulmonary exercise test before, and 3 months after, thoracoscopic sympathectomy. Eight healthy age-, gender- and BMI-matched controls were used as controls and underwent the same tests once. During tilt-table testing electrocardiogram, blood pressure, impedance cardiography and respiration were measured continuously, and efferent cardiac autonomic balance was estimated. The heart rate measured during orthostatic stress test was lowered after thoracoscopic sympathectomy (between-group; P = 0.01) due to a change in autonomic tone, with increased vagal (high-frequency power n.u.; P = 0.001), and reduced sympathetic efferent cardiac activity (low-frequency power n.u.; P < 0.001). Baroreceptor sensitivity measured during rest was increased (26 ± 13 vs 44 ± 19 ms/mmHg; P = 0.01), and diastolic blood pressure reduced after surgery (P = 0.01). The increases in systolic blood pressure and the sympathetic marker CCV-LF in response to orthostatic stress were higher before sympathectomy, with almost no increases post-surgically (condition × group interaction; P = 0.01 and P = 0.001, respectively). We found no change in post-procedure exercise capacity, although patients had a lower peak VO2 and maximal cardiac index than controls. Thoracoscopic sympathectomy changes the autonomic tone towards increased vagal activity; this is potentially cardioprotective. To our knowledge, this is the first study to show increased baroreceptor

Single-port one-stage bilateral thoracoscopic sympathicotomy for severe hyperhidrosis: prospective analysis of a standardized approach

PubMed Central

2013-01-01

Background Primary palmar and/or axillary focal hyperhidrosis is a frequent disorder characterized by excessive sweating beyond physiological needs, often leading to a substantial impairment of quality of life. Over the years several minimally invasive surgical treatments have been described, however results vary, and due to a lack of uniform surgical approach, technique and nomenclature are often difficult to compare. In this prospective study we sought to evaluate the safety and effectiveness of our standardized technique of single-port, one-stage bilateral thoracoscopic sympathicotomy. Methods On a prospective basis a hundred consecutive patients with severe or intolerable primary hyperhidrosis underwent one-stage bilateral single-port thoracoscopic sympathicotomy. Primary outcome was measured in pre- vs. post-operative Hyperhidrosis Disease Severity Scale scores. Location and extend of compensatory hyperhidrosis, and satisfaction with the procedure were registered. Results A significant reduction in mean Hyperhidrosis Disease Severity Scale score (3.69 ± 0.47 preoperatively vs. 1.06 ± 0.34 postoperatively) (p < 0.001) was observed. In 97 (97%) out of the 100 enrolled patients a >80% reduction in sweat production was achieved. Compensatory hyperhidrosis was seen in 27 patients (27%). It was rated as mild by 21 patients (78%) and as moderate by 6 (22%) of these patients. No severe compensatory hyperhidrosis was reported. Major complications, such as intraoperative bleeding, infections, and Horner’s syndrome were not observed. Conclusions Highly selective sympathicotomy at well-defined levels with a one-stage bilateral single-port transaxillary thoracoscopic approach is a save procedure, with excellent and reproducible immediate results in the treatment of primary palmar and/or axillary hyperhidrosis.

The objective of this study is to assess the use of a novel, double-lumen electrocautery tube (DLET) device for ablating the sympathetic nerve chain in patients with primary palmar hyperhidrosis (PPH). Forty-six patients with severe PPH were recruited into the study between November 2010 and February 2012. All patients underwent single port, bilateral video-assisted thoracoscopic sympathicotomy. Twenty-four patients were randomized to receive sympathicotomy using a conventional 5-mm electrocautery hook (hook group) and 22 patients were randomized to the DLET group. The mean postoperative follow-up period was 8.1 months (range: 1 to 15 months). After surgery the hands of all patients became dry and warm. Mean incision size was 10.6 ± 1.0 in the hook group and 6.5 ± 0.5 mm in the DLET group (p = 0.001). The mean pain score was 1.4 ± 0.6 with hook surgery and 0.9 ± 0.6 with the DLET device (p = 0.016). The mean operative time was longer in the hook group (36.8 ± 3.4 min) than in the DLET group (30.5 ± 3.9 min; p = 0.001). There were no significant differences between the two procedures in terms of hospital stay and compensatory sweating, or patient satisfaction. Pneumothorax occurred in two (8.3%) patients in the hook group and in one (4.5%) patient in the DLET group. None of the patients required chest drainage and none developed Horner syndrome. Single-port video-assisted thoracoscopic sympathicotomy using hook or DLET procedures is effective, safe, and minimally invasive method for palmar hyperhidrosis. The DLET device allows a shorter operation time, smaller incision, better cosmetic results, less pain, and better clarity of video, making it suitable for single-port thoracoscopic sympathicotomy.

Axillary hyperhidrosis: A review of the extent of the problem and treatment modalities.

PubMed

Singh, Sanjay; Davis, Harriet; Wilson, Paul

2015-10-01

The purpose of this review is to summarize the extent of the problem of axillary hyperhidrosis and treatment modalities available. The benefits and disadvantages of various treatments are reflected on with the hope of providing a starting point to investigate new ways of treating hyperhidrosis. A literature search was conducted using various databases and search criteria. Current treatments include aluminium chloride antiperspirants, iontophoresis, botox injections and endoscopic thoracic sympathectomy. Botox therapy is usually the most effective treatment, without surgery or unpleasant side effects. However it has to be administered by a skilled clinician and involves around 20 injections to treat axillary hyperhidrosis. Other ways of giving Botox are being developed, the most promising one being the use of microneedles which are able to penetrate the skin and deliver drugs to the target area of the dermis without causing pain. In comparison to the temporary effects of microneedles, laser and microwave therapies are also assessed as they offer the hope of permanent relief from hyperhidrosis. There is a considerable dearth in the literature on the management of axillary hyperhidrosis. Further study in larger populations with longer follow up times is critical to access the long term effects of treatment. Microneedles could be the future treatment of choice with the potential to deliver drugs in a safe and pain free way.

To estimate cost-effectiveness of botulinum toxin therapy for axillary hyperhidrosis compared to the standard surgical intervention of endoscopic thoracic sympathectomy (ETS). The validated dermatology life quality index questionnaire was given to patients attending for treatment over a 4 month period, to assess their quality of life (QoL) over the preceding week (n = 44). Follow-up was performed 4-6 weeks later by telephone using the same questionnaire to validate the effectiveness of the treatment. The duration of effect of the botulinum toxin treatment was also recorded and this data was used as the basis for cost effectiveness analysis. Using HIPE data, the baseline cost for single intervention using botulinum toxin and ETS was retrieved. Using figures provided by HIPE and expert opinion of the costs of complications, a stochastic model for 10,000 patients was used to evaluate the total costs for ETS including the complications. The results from the QoL analysis show that botulinum toxin therapy is a successful therapy for improvement of symptoms. It was revealed that the mean interval before recurrence of original symptoms after botulinum toxin therapy was 5.6 months. The baseline cost for both treatments are €389 for botulinum toxin and €9389 for uncomplicated ETS. The stochastic model yields a mean cost of €11,390 for ETS including complications. Treatments reached cost equivalence after 13.3 years. However, given the efficacy of the botulinum toxin therapy and the low risk we propose that botulinum toxin therapy for hyperhidrosis should be considered the gold standard.

Primary hyperhidrosis affects approximately 3% of the population and reduces quality of life in affected persons. Few studies have investigated the symptoms of anxiety, depression and hazardous alcohol consumption among those with hyperhidrosis and the effect of treatment with botulinum toxin. The first aim of this study was to investigate the effect of primary hyperhidrosis on mental and physical health, and alcohol consumption. Our second aim was to study whether and how treatment with botulinum toxin changed these effects. One hundred and fourteen patients answered questionnaires regarding hyperhidrosis and symptoms, including hyperhidrosis disease severity scale (HDSS), visual analog scale (VAS) 10-point scale for hyperhidrosis symptoms, hospital anxiety and depression scale (HADS), alcohol use disorder identification test (AUDIT) and short-form health survey (SF-36) before treatment with botulinum toxin and 2 weeks after. The age of onset of hyperhidrosis was on average 13.4 years and 48% described heredity for hyperhidrosis. Significant improvements were noted in patients with axillary and palmar hyperhidrosis regarding mean HDSS, VAS 10-point scale, HADS, SF-36 and sweat-related health problems 2 weeks after treatment with botulinum toxin. Changes in mean AUDIT for all participants were not significant. Primary hyperhidrosis mainly impairs mental rather than physical aspects of life and also interferes with specific daily activities of the affected individuals. Despite this, our patients did not show signs of anxiety, depression or hazardous alcohol consumption. Treatment with botulinum toxin reduced sweat-related problems and led to significant improvements in HDSS, VAS, HADS and SF-36 in our patients. © 2016 Japanese Dermatological Association.

The effectiveness of tap water iontophoresis for palmoplantar hyperhidrosis using a Monday, Wednesday, and Friday treatment regime.

2013-03-15

Primary focal hyperhidrosis is a benign condition of unknown etiology. Tap water iontophoresis has long been known to inhibit sweat production. The mechanism of reduced hyperhidrosis by iontophoresis is not completely clear. For operational convenience, our patients received their treatments at different intervals to those recommended by the manufacturer of the iontophoresis unit. We performed a retrospective audit to evaluate the effectiveness of tap water iontophoresis using this regimen. This new treatment regimen was effective at controlling palmoplantar hyperhidrosis. Minimal undesirable effects such as mild skin irritation and erythema were noted but none were severe enough to necessitate discontinuation of treatment. In conclusion, tap water iontophoresis is a safe and effective treatment of palmar and plantar hyperhidrosis when used on Monday, Wednesday, and Friday for 4 weeks. Continued treatment is needed to maintain the effect and many patients go on to purchase their own machines. This technique should be considered prior to systemic or aggressive surgical intervention.

There are many ways to treat focal hyperhidrosis, including surgeries for palmar and axillary hyperhidrosis. However, doctors and patients tend to be reluctant to perform surgery for plantar hyperhidrosis due to misconceptions and prejudices about surgical treatment. In addition, few studies have reported the outcome of surgeries for plantar hyperhidrosis. Therefore, the objective of this study was to determine the outcome (early and late postoperative satisfaction, complication, compensatory hyperhidrosis, recurrence rate, and efficiency) of surgical treatment for plantar hyperhidrosis. From August 2014 to October 2015, lumbar sympathetic block (LSB) was performed in 82 patients with plantar hyperhidrosis using clipping method. Limited video-assisted LSB was performed using 5 mm ligamax-clip or 3 mm horizontal-clip after identifying L3-4 sympathetic ganglion through finger-touch and endoscopic vision. Of the 82 patients, 45 were male and 37 were female. Their mean age was 26.38 years (range, 14-51 years). Mean follow-up time was 6.60 ± 3.56 months. Mean early postoperative satisfaction score was 9.6 on the 10th day postoperative evaluation. At more than 1 month later, the mean late postoperative satisfaction score was 9.2. There was no significant difference in early postoperative satisfaction score between clipping level L3 and L4/5. However, late postoperative satisfaction score was significantly better in the L3 group than that in the L4/5 group. Patient's age and body mass index did not affect the satisfaction score. However, male patients and patients who had history of hyperhidrosis operation showed higher satisfaction score than others. Limited video-assisted LSB using clip provided good results with minimal complications and low compensatory hidrosis, contrary to the prejudice toward it. Therefore, surgical treatment is recommended for plantar hyperhidrosis.

BACKGROUND Primary hyperhidrosis (PH) can lead to mood changes due to the inconveniences it causes. OBJECTIVE This study aimed to examine the existence of anxiety and depression in patients with severe primary hyperhidrosis who sought treatment at a medical office. METHODS The questionnaire "Hospital Anxiety and Depression Scale" was used for 197 individuals, in addition to the chi square test and Fisher exact test, p <0.05. RESULTS There was an increased prevalence of anxiety (49.6%) but not of depression (11.2%) among patients with PH, with no link to gender, age or amount of affected areas. Palmar and plantar primary hyperhidrosis were the most frequent but when associated with the presence of anxiety, the most frequent were the axillary (p = 0.02) and craniofacial (p = 0.02) forms. There was an association between patients with depression and anxiety (p = 0.001). CONCLUSIONS the involvement of Primary hyperhidrosis was responsible for a higher prevalence of anxiety than that described among the general population and patients with other chronic diseases. Depression had a low prevalence rate, while mild and moderate forms were the most common and frequently associated with anxiety. The degree of anxiety was higher in mild and moderate types than in the severe form. PMID:24770497

Primary hyperhidrosis is characterized by excessive sweating in a defined region of the body. It should not be considered a purely cosmetic problem as it has a significant impact on the social and professional relationships of affected individuals. The aim of this study was to determine the clinical profile of patients with primary hyperhidrosis and assess the results obtained with the use of botulinum toxin type A (BTX-A) in clinical practice. The study included 52 patients (39 women and 13 men) with a diagnosis of primary hyperhidrosis treated for the first time with BTX-A. All patients completed a questionnaire that included the following information: age; sex; profession; age at onset, family history, and site of hyperhidrosis; accompanying signs and symptoms, and previous treatment; time to effect of BTX-A; local or systemic side effects; and severity of hyperhidrosis before and after BTX-A treatment. Primary hyperhidrosis began during puberty in 61.5% of the patients included in the study, 75% were women, and the mean age was 29.9 years. In 36.5% of patients, first-degree relatives also had primary hyperhidrosis. Hyperhidrosis was classified as palmar in 61.5% of cases, plantar in 53.8%, and axillary in 59.6%. Other sites were affected less frequently. The most common accompanying symptoms were facial erythema (32.7%), palpitations (30.7%), muscle tension (28.8%), shivering (23%), and headache (17.3%). Treatment with BTX-A was well tolerated and there was a highly significant reduction in the severity of hyperhidrosis 2 months after performing the treatment (P<0.001).

Endoscopic thoracic sympathectomy (ETS) is the preferred surgery for treatment of intractable palmar hyperhidrosis (PH). General anesthesia with onelung collapsed ventilation (OLCV) using single-lumen tracheal tube (SLT), is our preferred anesthetic technique for ETS. Intrapleural CO(2) insufflation (capnothorax) was used to ensure lung collapse. The current study examined the effects of capnothorax on dynamic lung compliance (DLC) of the ventilated lung during ETS. After obtaining written informed consent, 10 adult male patients ASA I&II undergoing ETS were studied. Their average age and weight were 25 +/- 7 yr and 67 +/- 8 kg. General anesthesia with SLT and OLCV technique was used. Capnothorax with intrapleural pressure (IPP) of 10 mmHg was initially used, then it was reduced and maintained at 5 mmHg throughout the operation. Anesthesia delivery unit (Datex Ohmeda type A_Elec, Promma, Sweden) was used where airway pressures and DLC were displayed during OLCV. A computer program (SPSS 9.0 for Windows; SPSS Inc., Chicago, IL) was used for statistical analysis of the data obtained. One way analysis of variance (ANOVA) was used for analysis of data before, during and after OLCV. P<0.05 was considered significant. The mean values of the DLC were 52 +/- 6, 30 +/- 3, 39 +/- 5 and 53 +/- 9 ml/cmH(2)O before, during (at 10 and 5 mmHg IPP) and after OLCV respectively with significant differences before and at 10 and 5mmHg IPP. In conclusions, during OLCV and capnothorax for ETS, DLC tends to decrease with increasing of intrapleural CO(2) insufflation pressure. However, in short procedures it has no deleterious postoperative effect. To the best of our knowledge this is the first study performed to investigate DLC changes during OLCV with capnothorax.

Hyperhidrosis (HH) is a condition characterized by excessive sweating or perspiration. General population, especially in developing countries like India are seldom aware of this condition and sparsely seek medical attention. The tropical climate and the environment also influence this condition to a greater extent. This can be a hindrance in their professional and social life. Though, it is a widely explored topic, studies on hyperhidrosis from India are rare. The current study was aimed at estimating the prevalence of hyperhidrosis among college students subjectively and to assess the quality of life using Dermatology Life Quality Index (DLQI). Five hundred students with age ranging from 17 to 21 years of both genders were included in this study using convenient sampling method. After explaining the study and getting written consent, the students were requested to respond to two questionnaires, one for the subjective diagnosis of hyperhidrosis using a standardized questionnaire developed by North Jersey Thoracic Surgical Associates and the other to assess the quality of life using DLQI. Based on the subjective prevalence scores, the students were divided into 3 groups as "Not bothersome" group, "Somewhat bothersome group" and "Extremely bothersome" group. The DLQI scores of these three groups were compared by ANOVA using SPSS 21.0. The study revealed that overall, 38% of the students were suffering from somewhat bothersome to extremely bothersome hyperhidrosis. Gender analysis showed that male students were affected more (58%), especially with palmar hyperhidrosis and were significantly requiring treatment when compared to female students. Analysis of DLQI scores using ANOVA revealed the fact that overall quality of life was significantly affected in almost 35% of students to the extent that they require appropriate treatment and care. This study brings into light the higher prevalence of hyperhidrosis and also its impact on the quality of life among college

The treatment options for localized hyperhidrosis include antiperspirants, anticholinergics, iontophoresis, botulinum toxin and surgery. Tap water iontophoresis (TWI) involves immersing the affected area in tap water and passing a small electrical current through the area. Our aim was to assess the success of this therapy in a pediatric cohort. Retrospective case note review of all patients younger than 18years who underwent TWI between 2002 and 2015. Demographic data, number of treatment sessions, side effects and overall success were analyzed. Individuals undergo 7 treatments over 4weeks. A positive outcome was determined as an improvement in symptoms. Pre- and posttreatment hyperhidrosis disease severity scale (HDSS) was measured. Data are presented as mean (range). Statistical analysis was by paired t-test. A P value of <0.05 was regarded as significant. There were 43 patients (30 females) with a mean age of 15 (8-17) years. Palmar and/or plantar hyperhidrosis (PPH) was present in 39/43 (91%) patients. Axillary hyperhidrosis (AH) was present in 19/43 (44%) patients. All patients (with the exception of one) underwent 7 sessions (5-7). Side effects included paresthesia (88%), pruritus (26%), pain (26%), erythema (14%), dryness (12%) as well as vesicle formation and abrasions in one patient (2%). A positive outcome was found in 84% (36/43) of patients. There was a significant reduction in mean HDSS (pre 3.5 vs. post 2; P=0.0001). TWI is a safe and effective modality of treatment for both PPH and AH in the pediatric population, with minimal side effects. Pediatric surgeons should offer this treatment option before considering more invasive surgical procedures. IV: Retrospective study. Crown Copyright © 2017. Published by Elsevier Inc.

Cruddas, L; Baker, D M

2017-06-01

Primary hyperhidrosis is a condition characterized by excessive sweating. Patients are treated off-license with oral anticholinergic medications and report adverse events associated with systemic anticholinergic interactions. This review assesses clinical evidence of efficacy, impact on quality of life and adverse events associated with oral anticholinergic therapy for primary hyperhidrosis. PRISMA guidelines were implemented to complete a systematic review (PROSPERO:CRD42016036326). MEDLINE, EMBASE and PubMed were searched from 1946 to 2015. Inclusion criteria included observational and experimental studies, anticholinergic medication use in primary hyperhidrosis, oral therapy and clear diagnostic and outcome measures. Twenty-three articles relevant to the inclusion criteria were analysed. Oxybutynin therapy improved symptoms in an average of 76.2% (range 60-97%) patients and improved QOL in 75.6% (range 57.6-100%) of patients. Methantheline bromide therapy was associated with a 41% reduction in axillary sweating, 16.4% reduction in palmar sweating, 25% decrease in HDSS score and 40.9% increase in DLQI score. Outcome measures of glycopyrrolate therapy were too variable to collate. Dry mouth was reported in 73.4% (range 43.3-100%) of participants taking oxybutynin 10 mg/day, 38.6% (range 27.8-63.2%) of patients taking glycopyrrolate and 68.8% of patients taking methantheline bromide. Nine studies reported that patients stopped therapy due to adverse events. In eight of these studies, a mean of 10.9% of total participants ceased treatment due to dry mouth. Evidence of oral anticholinergic therapy for hyperhidrosis is limited. However, its use is associated with improvement in quality of life and clinical symptoms but at the cost of considerable adverse events. © 2016 European Academy of Dermatology and Venereology.

Primary focal hyperhidrosis is a common condition that negatively impacts quality of life for many pediatric patients and can be challenging to treat. Standard treatments for hyperhidrosis can be used with success in many patients, and newer therapies and techniques offer options that have demonstrated efficacy and safety. This review highlights standard therapies for primary focal hyperhidrosis as well as the most recent technique advancements and alternative treatment options. The standard approach to treating primary focal hyperhidrosis remains initiation of topical preparations, followed by advancement to systemic medications, local administration of medication and/or surgical procedures. Recent studies focus on enhancing tolerability of topical preparations as well as evaluating the efficacy of neuromodulator injections, oral anticholinergic medications and laser therapy. Microwave technology has also been introduced for the treatment of focal hyperhidrosis with promising results. Many therapies exist for hyperhidrosis, and each treatment plan must be evaluated on a patient-by-patient basis. Advances in standard therapies and emergence of new treatment techniques are the main emphases of current published literature on hyperhidrosis. This article presents recent therapeutic options as well as updates on more established strategies to help practitioners treat this challenging condition.

Hyperhidrosis is a skin disorder characterized by excessive sweating that often causes significant impairment in social, occupational, and emotional wellbeing. Hyperhidrosis is thought to affect 2.8% of the US population and can be of primary or secondary origin. Primary hyperhidrosis is usually bilateral, symmetric, and focal. The most common focal sites include, but are not limited to, the palms, soles, and axillae. Secondary hyperhidrosis is usually caused by an underlying medical condition or medication. Secondary hyperhidrosis must be ruled out before a diagnosis of primary hyperhidrosis is made. Copyright © 2014 Elsevier Inc. All rights reserved.

Oral anti-cholinergic medications reduce generalized hyperhidrosis, but the effectiveness of topical anticholinergic solutions on axillary hyperhidrosis is unclear. This study determines the initial effectiveness of 1% and 2% topical glycopyrrolate spray and compares this with Botulinum toxin type A injections for the management of axillary hyperhidrosis. In a non-randomized, consecutive patient, prospective questionnaire, treatment comparison study, 40 patients with axillary hyperhidrosis were allocated to one of four study groups (10 patients to each group): (a) 1% glycopyrrolate spray, (b) 2% glycopyrrolate spray, (c) subcutaneous Botulinum toxin type A injections, (d) no treatment. Clinical outcomes were measured by comparing a prospectively administered questionnaire, completed both pre-treatment and 6 weeks after starting treatment. Forty healthy volunteers without axillary hyperhidrosis completed the same questionnaire. The three treatment groups showed a significant (P < 0.05) improvement in their hyperhidrosis scores following treatment. The degree of improvement was less for the 1% glycopyrrolate group when compared with the Botulinum toxin type A group (P < 0.05), but there was no difference in treatment outcomes between the 2% glycopyrrolate and Botulinum toxin type A groups. No treatment group experienced reduced hyperhidrosis to a level similar to those without hyperhidrosis. Patients in both, the 2% glycopyrrolate and Botulinum toxin type A groups reported a significant improvement in axillary hyperhidrosis symptoms. These included reduction in psychologically precipitating factors (e.g. public speaking) and axillary hyperhidrosis-specific physical effects (e.g. limitation of clothing choice). Topical glycopyrrolate spray could provide a further treatment modality to manage axillary hyperhidrosis. © 2016 European Academy of Dermatology and Venereology.

Hyperhidrosis can be localized or generalized and may cause the patient significant discomfort. Localized hyperhidrosis is usually primary, often begins in adolescence and is partly based on genetic dispositions. As a rule it does not necessitate investigations for secondary causes (e.g. endocrine or neurologic conditions). Generalized hyperhidrosis is commonly associated with environmental or lifestyle factors, and sometimes physiological factors. In new-onset generalized sweating of unclear origin, it may be appropriate to consider secondary causes (underlying diseases, medications, infections). Relatively effective symptomatic treatments are available in localized hyperhidrosis. The treatment of generalized hyperhidrosis is almost always directed against the underlying factors.

Hyperhidrosis is excessive sweating beyond what is expected for thermoregulatory needs. Nearly 3 % of the population has hyperhidrosis. It may be primary or secondary to medications or general medical conditions, including diabetes mellitus, hyperthyroidism, Parkinson disease, etc. History taking and clinical examination are essential to differentiate primary from secondary origins. Blood tests and a consultation with a specialist (endocrinologist, neurologist) is sometimes necessary to establish the diagnosis. The management of secondary hyperhidrosis involves the treatment of the underlying cause. For primary hyperhidrosis, it depends on its severity and the sites affected. This article will review the treatments for primary hyperhidrosis.

Surgical scars on the palmar surface of the hand may lead to functional and also aesthetic and psychological consequences. The objective of this study was to introduce a new incision technique for periarterial sympathectomy of the hand and to compare the results of the new two-step incision technique with those of a Koman incision by using an objective questionnaire. A total of 40 patients (17 men and 23 women) with intractable Raynaud's disease or syndrome underwent surgery in our hospital, conducted by a single surgeon, between January 2008 and January 2013. Patients who had undergone extended sympathectomy or vessel graft were excluded. Clinical evaluation of postoperative scars was performed in both groups one year after surgery using the patient and observer scar assessment scale (POSAS) and the Wake Forest University rating scale. The total patient score was 8.59 (range, 6-15) in the two-step incision group and 9.62 (range, 7-18) in the Koman incision group. A significant difference was found between the groups in the total PS score (P-value=0.034) but not in the total observer score. Our analysis found no significant difference in preoperative and postoperative Wake Forest University rating scale scores between the two-step and Koman incision groups. The time required for recovery prior to returning to work after surgery was shorter in the two-step incision group, with a mean of 29.48 days in the two-step incision group and 34.15 days in the Koman incision group (P=0.03). Compared to the Koman incision, the new two-step incision technique provides better aesthetic results, similar symptom improvement, and a reduction in the recovery time required before returning to work. Furthermore, this incision allows the surgeon to access a wide surgical field and a sufficient exposure of anatomical structures.

Focal hyperhidrosis: diagnosis and management

2005-01-01

HYPERHIDROSIS, A CONDITION CHARACTERIZED by excessive sweating, can be generalized or focal. Generalized hyperhidrosis involves the entire body and is usually part of an underlying condition, most often an infectious, endocrine or neurologic disorder. Focal hyperhidrosis is idiopathic, occurring in otherwise healthy people. It affects 1 or more body areas, most often the palms, armpits, soles or face. Almost 3% of the general population, largely people aged between 25 and 64 years, experience hyperhidrosis. The condition carries a substantial psychological and social burden, since it interferes with daily activities. However, patients rarely seek a physician's help because many are unaware that they have a treatable medical disorder. Early detection and management of hyperhidrosis can significantly improve a patient's quality of life. There are various topical, systemic, surgical and nonsurgical treatments available with efficacy rates greater than 90%–95%. PMID:15632408

Compensatory hyperhidrosis due to the treatment for focal primary hyperhidrosis can be devastating and life-altering. The purpose of this paper is to discuss use of the iodine starch test and dilute botulinum toxin to decrease compensatory hyperhidrosis over large surface areas. A large area of the trunk affected by compensatory hyperhidrosis was treated with dilute botulinum toxin therapy using a starch iodine test for localization. The patient had exceptional results with his compensatory truncal sweating returning to normal and remaining stable for multiple months. Treating compensatory hyperhidrosis of large surface areas with dilute botulinum toxin therapy is effective and safe. © 2013 Wiley Periodicals, Inc.

Hyperhidrosis: Anatomy, Pathophysiology and Treatment with Emphasis on the Role of Botulinum Toxins

Clinical features, anatomy and physiology of hyperhidrosis are presented with a review of the world literature on treatment. Level of drug efficacy is defined according to the guidelines of the American Academy of Neurology. Topical agents (glycopyrrolate and methylsulfate) are evidence level B (probably effective). Oral agents (oxybutynin and methantheline bromide) are also level B. In a total of 831 patients, 1 class I and 2 class II blinded studies showed level B efficacy of OnabotulinumtoxinA (A/Ona), while 1 class I and 1 class II study also demonstrated level B efficacy of AbobotulinumtoxinA (A/Abo) in axillary hyperhidrosis (AH), collectively depicting Level A evidence (established) for botulinumtoxinA (BoNT-A). In a comparator study, A/Ona and A/Inco toxins demonstrated comparable efficacy in AH. For IncobotulinumtoxinA (A/Inco) no placebo controlled studies exist; thus, efficacy is Level C (possibly effective) based solely on the aforementioned class II comparator study. For RimabotulinumtoxinB (B/Rima), one class III study has suggested Level U efficacy (insufficient data). In palmar hyperhidrosis (PH), there are 3 class II studies for A/Ona and 2 for A/Abo (individually and collectively level B for BoNT-A) and no blinded study for A/Inco (level U). For B/Rima the level of evidence is C (possibly effective) based on 1 class II study. Botulinum toxins (BoNT) provide a long lasting effect of 3–9 months after one injection session. Studies on BoNT-A iontophoresis are emerging (2 class II studies; level B); however, data on duration and frequency of application is inconsistent. PMID:23612753

Hyperhidrosis is a chronic disease characterized by increased sweat production. Local injections of botulinum toxin A (BTX-A) have been extensively used for treatment of primary hyperhidrosis (idiopathic). The current treatment for this condition involves several intradermal injections, resulting in poor patient compliance due to injection-related pain. Therefore, new protocols, including an improved anesthetic regimen, are required. We designed the present study to determine whether JetPeel™-3, a medical device used for transdermal delivery of drugs by jet nebulization, could be used to deliver lidocaine prior to the standard multiple BTX-A injections or deliver lidocaine together with BTX-A in order to determine the protocol giving better results in terms of procedure-related pain, sweating, and patient satisfaction in subjects affected by primary axillary, palmar or plantar hyperhidrosis. Twenty patients with a visual analog scale (VAS) sweating score ≥ 8 cm were randomized to receive lidocaine 2% (5 mL) delivered by JetPeel™-3 followed by multiple injections of BTX-A (100 units) or lidocaine 2% (5 mL) and BTX-A (50 units) delivered together by JetPeel™-3. Effect of treatment on sweating was measured by VAS (0= minimum sweating; 10= maximum sweating) at 3-month follow-up. Pain induced by the procedure was assessed by VAS (0= minimum pain; 10= maximum pain) immediately after the procedure. Patient satisfaction was assessed at 3-month follow-up using a 5-point scale (1= not at all satisfied; 2= not satisfied; 3= partially satisfied; 4= satisfied; 5= highly satisfied). Both treatment modalities reduced sweating at 3-month follow-up, if compared with baseline (all P<0.001). Delivery of lidocaine and BTX-A by JetPeel™-3 resulted in lower procedure-related pain and reduced sweating, if compared with lidocaine delivered by JetPeel™-3 followed by multiple BTX-A injections (all P<0.001). Patient satisfaction with the procedure was higher in the group

All patients (36 hands) with connective tissue disorders who underwent periarterial sympathectomy of the hand alone or in conjunction with vascular bypass at our institution between 1995-2013 were reviewed. The durable resolution of ulcers was significantly higher in patients treated by periarterial sympathectomy and bypass than in patients treated by periarterial sympathectomy alone. Although there were more digital amputations in patients treated by periarterial sympathectomy alone, the difference was not statistically significant. Vascular bypass in conjunction with sympathectomy may be better than sympathectomy alone in patients with digital ischaemia related to connective tissue disorders. IV.

Special considerations for children with hyperhidrosis.

Bohaty, Benjamin R; Hebert, Adelaide A

2014-10-01

Hyperhidrosis, characterized by excess sweat production, affects children and adults. Primary focal hyperhidrosis affects any anatomic region with sweat appendages present. Primary hyperhidrosis has traditionally been considered a problem for adults, but approximately 1.6% of adolescents and 0.6% of prepubertal children are affected. Psychological and social development and well-being are often affected, leading to profound emotional and social distress. Quality of life can be improved by early diagnosis and therapy; however, underdiagnosis and lack of knowledge regarding therapeutic options has hindered optimization of therapy in the pediatric population. This article reviews the treatment options for hyperhidrosis with a focus on the pediatric population. Copyright © 2014 Elsevier Inc. All rights reserved.

Investigation on aetiological factors in patients with hyperhidrosis.

Hyperhidrosis is a condition where the amount of sweat released to skin surface increases due to the over-active eccrine sweat glands. Hyperhidrosis causes considerable psychosocial distress in affected people. It affects the quality of life and leads to social anxiety disorders. No study has been conducted in our country to investigate the epidemiological, clinical, and laboratory data of patients with hyperhidrosis. In this study, we aimed to retrospectively investigate the clinical and demographic characteristics, causes of sweating and laboratory findings in patients treated for hyperhidrosis at our outpatient clinic and to compare these data with the literature data. A retrospective review was conducted on medical records of patients diagnosed with and treated for hyperhidrosis at outpatient clinic between 2014 and 2017. Adults aged over 18 years were included in study. Age and gender of patients, type and localization of sweating, duration of disease, age of onset of sweating, presence of stress, fever, joint pain and comorbidity, family history, medication use, and examination results were recorded. Records of a total of 70 patients consisting of 30 men and 40 women with hyperhidrosis were examined. Overall mean age was 37.1 years. Mean age was 41 years in women and 32 years in men. Most frequent forms were palmoplantar and axillary hyperhidrosis for primary hyperhidrosis (primary HH), and head-neck and generalized hyperhidrosis for secondary hyperhidrosis (secondary HH). Most common comorbidities were diabetes mellitus, thyroid disease, non-specific joint and bone pain, cardiovascular disease, and neuropsychiatric disease. Cases with secondary HH had a history of drug use (antithyroid drugs, nonsteroidal anti-inflammatory drugs, antidiabetic agents, antidepressants, and antihypertensives). This is the first study that investigated the characteristics of patients with primary and secondary HH in our country. These characteristics can help determine

Residual limb dermatologic problems are a common concern among young active traumatic amputee patients who strive to maintain an active lifestyle. Hyperhidrosis of residual limbs is a recognized inciting factor that often contributes to residual limb dermatoses and is driven by the design of the prosthetic liner covering the residual limb. Treatment of hyperhidrosis in this population presents a unique challenge. Several accepted treatments of hyperhidrosis can offer some relief but have been limited by lack of results or side-effect profiles. Microwave thermal ablation has presented an enticing potential for residual limb hyperhidrosis.

Topical therapies in hyperhidrosis care.

Primary focal hyperhidrosis affects 3% of the US population; about the same number as psoriasis. More than half of these patients have primary focal axillary hyperhidrosis: sweating that is beyond what is anticipated or necessary for thermoregulation. Most topical therapies are based on aluminum salts, which work by a chemical reaction that forms plugs in the eccrine sweat ducts. Topical anticholinergics may also be used. Instruction on proper methods and timing of antiperspirants enhances effect and may be effective alone or in combination with other treatments in patients with hyperhidrosis.

Kim, Do Hyung; Paik, Hyo Chae; Lee, Doo Yun

2004-08-01

The main cause of dissatisfaction after sympathetic trunk blocking surgery (T2 sympathectomy, sympathetic clipping) for craniofacial hyperhidrosis is compensatory sweating. Preserving sympathetic trunk may decrease the incidence of compensatory sweating, and we introduce T2 ramicotomy, which may better preserve the sympathetic nerve trunk in order to reduce compensatory sweating. From January 2000 to November 2002, video-assisted thoracoscopic (VAT) T2 sympathetic clipping and VAT ramicotomy were performed in 44 patients suffering from craniofacial hyperhidrosis. Twenty-two patients underwent T2 sympathetic clipping (group 1), and 22 underwent division of T2 rami-communicantes (group 2). We retrospectively analyzed the rate of satisfaction, dryness of face, and grade of compensatory sweating. Both groups were similar with respect to facial dryness (P = 0.099). Group 1: excessive dry 5 patients (22.7%), dry 17 patients (77.3%); group 2: excessive dry 3 patients (13.6%), dry 15 patients (68.1%), and persistent sweating 4 patients (18.3%). The rate of satisfaction was 77.3% in group 1, and 63.6% in group 2 with no significant difference (P > 0.05). The rate of compensatory sweating in group 2 (72.7%) was significantly lower than in group 1 (95.4%) (P < 0.039). The chance of embarrassing and disabling compensatory sweating was lower in group 2 than in group 1; 76.5% (embarrassing in 8 patients, disabling in 9) in group 1, and 36.4% (embarrassing in 7 patients, disabling in 1) in group 2 which was statistically significant (P < 0.006). T2 ramicotomy for craniofacial hyperhidrosis lowers the rate of compensatory sweating and excessive dryness of face compared to T2 clipping.

Lower limb sympathectomy assessed by laser Doppler blood flow and transcutaneous oxygen measurements.

In a retrospective study of critical ischaemia of the lower limb, sympathectomy appeared to be of value in the majority of patients. We therefore assessed sympathectomy by measuring skin blood flow before and after the procedure using laser Doppler flowmetry (LDF) and transcutaneous oxygen tension (TCpO2) techniques. Twenty patients underwent chemical sympathectomy and there was one surgical procedure. Measurements were performed before and 1 week after sympathectomy below the knee and on the forefoot. Symptomatic improvement occurred in 20 of 21 patients. This study demonstrates that skin blood flow in the leg and foot is improved by sympathectomy and confirms objectively our clinical impression.

Cervicothoracic Sympathectomy is a common indication in the treatment of Raynaud Syndrome, Palmer Hyperhidrosis or Acute Ischemia of the superior limb. Nonetheless, almost a century ago it represented one of the first innovative attempts in curing coronary heart disease. Nowadays, this indication is no more than a footnote in a volume on the History of Medicine, and a trivia fact for medical history enthusiasts. The operation's history is rather conflicting. A young Romaninan surgeon, Victor Gomoiu seems to have come up with the idea, in the early 20th century. However, his contribution remains unknown, after his successful collaboration with the famous surgeon and anatomist, Thoma Ionescu unfortunately turns into a dispute. This procedure was once thought cutting-edge. Furthermore it is the starting point for cardiovascular surgery. Whoever sparked the idea, gains an important place in the hall of fame of international surgery, that is why it is important to know its creator.

Pathophysiology of Hyperhidrosis.

PubMed

Schick, Christoph H

2016-11-01

Studies and case reports on excessive sweating frequently state that hyperhidrosis is a disease whose origin and mechanism are unknown. However, the term excessive is rarely based on systematic diagnostic measurements, instead being a description of the symptoms from patient histories, which suggests that hyperhidrosis is purely a problem involving the quantity of sweat, whereas it is a change in the control mechanism of sweating in which the need for and production of sweat are strongly disproportionate. This lack of proportion is perceived by those affected to be a limitation of activities of daily living and is thus pathologic. Copyright © 2016 Elsevier Inc. All rights reserved.

Hyperhidrosis in association with efavirenz.

Hyperhidrosis may be an adverse drug event (ADE) induced by the effect on any of the components of human thermoregulation. Some of our efavirenz (EFV)-treated patients have reported excessive nocturnal sweating that resolved after dose reduction. A representative clinical case of a male patient being treated with a night-time 600-mg dose of EFV who reported severe nocturnal sweating is reported here. His EFV plasma concentrations were always above normal and he was homozygous for a deficient function-allele of CYP2D6; for this reason, his EFV dose was reduced to 400mg=d. Simultaneous with this reduction, the patient described a progressive decrease in nocturnal sweating until its complete disappearance 15-20 days after this new drug dosage. The mechanism explaining sweating could be similar to the one suggested for hyperhidrosis related to serotonin uptake inhibitors, because this hyperhidrosis is episodic, nocturnal, and dose dependent. Hyperhidrosis could correspond to a dose-dependent ADE induced by EFV, therefore, a reduction of EFV from 600 to 400mg/d seems to control it. EFV crosses the hematoencephalic barrier and reaches a mean concentration in the cerebroespinal fluid equivalent to 0.69% of the plasma concentration. The ability of EFV to accessing the central nervous system (CNS) could explain an effect on thermoregulation. Hyperhydrosis is not easily discovered through a routine anamnesis because it is not noted on the EFV package insert, so its incidence may be higher than expected. Additionally, hyperhidrosis may be an indicator of elevated EFV plasma concentrations and hence may be controlled through a reduction of dose.

Air embolism is a relatively rare complication of thoracoscopic surgery. Open supraclavicular sympathectomy was indicated to overcome the risk of re-embolization. A novel video-assisted technique was performed. conclusions: The previously prevalent open supraclavicular sympathectomy is a good choice for avoiding air embolism. Laparoscopic instrumentation and technology can be used to improve open procedures, especially when exposure and visibility are limited.

Pitted keratolysis (PK) is a plantar skin disorder mainly caused by coryneform bacteria. A common treatment consists of the topical use of erythromycin. Hyperhidrosis is considered a predisposing factor for bacterial proliferation and, consequently, for the onset of PK. The aim of this study was to evaluate the relationship between PK erythromycin and hyperhidrosis. All patients with PK seen in Sant'Andrea Hospital, between January 2009 and December 2011, were collected. PK was clinically and microscopically diagnosed. All patients underwent only topical treatment with erythromycin 3% gel twice daily. At the beginning of the study and after 5 and 10 days of treatment, a clinical evaluation and a gravimetric measurement of plantar sweating were assessed. A total of 97 patients were diagnosed as PK and were included in the study. Gravimetric measurements showed that in 94 of 97 examined patients (96.90%) at the time of the diagnosis, there was a bilateral excessive sweating occurring specifically in the areas affected by PK. After 10 days of antibiotic therapy, hyperhidrosis regressed together with the clinical manifestations. According to these data, we hypothesize that hyperhidrosis is due to an eccrine sweat gland hyperfunction, probably secondary to bacterial infection. © 2013 Wiley Periodicals, Inc.

Axillary hyperhidrosis is characterized by an increased amount of sweat production, localized to the armpits, to compensate for environmental conditions and to control thermoregulation. It affects about 3.12% of the US population. It has a significant effect on one's psychological and physical health, as well as one's occupational life. The objective of this paper is to review the epidemiology, clinical presentation, pathophysiology, histology, genetics, and management and treatment of axillary hyperhidrosis.

The excessive sweating of hyperhidrosis creates profound psychosocial, professional, and financial burdens on the individual sufferer; it contributes to impaired self-worth and self-efficacy, decreased satisfaction in all relationships, avoidance of specific careers, and increased expenditures on everything from clothing to medical treatment. Despite morbidity equal to other well-known dermatologic conditions, hyperhidrosis has historically been underacknowledged and undertreated because of the lack of accessible, scientifically accurate information and dispersal of that information within patient and medical communities. Thankfully, the development of the Internet and the work of the not-for-profit International Hyperhidrosis Society (IHHS) have increased awareness of hyperhidrosis. Copyright © 2014 Elsevier Inc.

Thermotherapy has been established between conservative and surgical options as a minimally invasive method for the treatment of axillary hyperhidrosis. The objective of this study was to present radiofrequency thermotherapy (RFTT) as a safe and effective new treatment method. Thirty adult patients with pronounced axillary hyperhidrosis were treated with RFTT with noninsulated microneedles 3 times at intervals of 6 weeks. Subjective improvement was rated using the Hyperhidrosis Disease Severity Scale (HDSS) and Dermatology Life Quality Index (DLQI). Satisfaction and estimated reduction of sweating were monitored. Objective measurements were made using gravimetry. Adverse effects were recorded in follow-up. At the 6-month follow-up, improvement in sweating was seen in 27 patients. The HDSS dropped from 3.4 to 2.1, the DLQI improved significantly from 16 to 7. The gravimetric measurements of sweat were reduced from 221 to 33 mg/min. The average reduction of sweating was reported to be 72%. Adverse effects were generally mild and improved rapidly. Radiofrequency thermotherapy was shown to be an effective and minimally invasive treatment option for axillary hyperhidrosis. Patients described their sweating as normal. The method clearly has the potential to normalize axillary sweating.

Primary focal hyperhidrosis is a disease of unknown cause with profuse perspiration of local sites (head, face, palms, soles of feet, and axillae) that adversely affects daily life. Guidelines have been proposed in the USA [1], Canada [2], and Japan [3]. The symptoms impair quality of life, with significant negative effects on daily existence and personal relationships. The current goal in medical practice for patients with hyperhidrosis is to provide guidance and encourage coping skills for a normal daily life, as well as give appropriate advice regarding treatment options. On occasion, in order to improve quality of life, it is necessary to recommend surgical therapy when conservative treatment fails; this requires an understanding of the mechanisms of available treatments and their effects. This paper reviews theories of primary focal hyperhidrosis with regard to pathology, epidemiology, and treatment. © 2016 S. Karger AG, Basel.

Hyperhidrosis is the excessive production of sweating, which can be primary and focal or secondary to various pathologies. The exact cause of primary focal hyperhidrosis is still unknown, although a genetic basis is recognized, and its prevalence varies from 1% to 2.8%. The most affected sites are the armpits, palms, soles and face. It causes much discomfort, affects the quality of life, and is estimated to be undervalued by health professionals. Many treatment options are proposed, both clinical and surgical. The aim of this review is to focus on the treatment of hyperhidrosis with oxybutynin, an anticholinergic drug originally used to control overactive bladder. PMID:28538882

Hosp, Christine; Hamm, Henning

Hyperhidrosis affects 4.8% of the U.S. population and has been underestimated by physicians for long time despite considerable interference with quality of life. Many patients suffer from primary (idiopathic) hyperhidrosis which results from over-activity of sympathetic nerves and is restricted to specific body areas, mostly the axillae, palms, soles, or head. Secondary hyperhidrosis is caused by an underlying disease or the intake of medications and often involves large parts of the body. Numerous effective therapies with topical or systemic drugs and surgical options are available. Areas covered: Efficacy and safety data on aluminum salts, anticholinergic drugs for topical or systemic application, and on intradermal botulinum toxin injections used to treat hyperhidrosis are critically evaluated, including data from clinical trials with focus on possible side effects and long-term complications in dispute. Expert opinion: Hyperhidrosis often responds well to available therapies. Depending on the type of hyperhidrosis treatment should be topical/local or systemic. Most of the side effects are mild, transient and easily manageable. In case of systemic treatment with anticholinergics low dosing and up-titration of medication is necessary to avoid severe adverse effects. Concerns about the promotion of breast cancer and Alzheimer disease by topical aluminum salts are unsolved.

To study the anatomical basis of micro transverse flap pedicled with the superfical palmar branch of radial artery from the palmar wrist for using this free flap to repair soft tissue defect of the finger. Thirty-eight fresh upper limb specimens (22 males and 16 females; aged 26-72 years with an average of 36 years; at left and right sides in 19 limbs respectively) were dissected and observed under operating microscope. Two specimens were made into casting mould of artery with bones, and 2 specimens were injected with red emulsion in radial artery. Thirty-four specimens were injected with 1% gentian violet solution in the superfical palmar branch of the radial artery. A transverse oval flap in the palmar wrist was designed, the axis of the flap was the distal palmar crease. The origin, distribution, and anastomosis of the superfical palmar branch of the radial artery were observed. The superficial palmar branch of the radial artery was constantly existed, it usually arises from the main trunk of the radial artery, 1.09-3.60 cm to proximal styloid process of radius. There were about 2-5 branches between the origin and the tubercle of scaphoid bone. The origin diameter was 1.00-3.00 mm, and the distal diameter at the styloid process of radius was 1.00-2.90 mm. The venous return of flap passed through 2 routes, and the innervations of the flap mainly from the palmar cutaneous branch of the median nerve. The area of the flap was 4 cm x 2 cm-6 cm x 2 cm. The origin and courses of the superficial palmar branch of the radial artery is constant, and its diameter is similar to that of the digital artery. A transverse oval flap pedicled with the superfical palmar branch of radial artery in the palmar wrist can be designed to repair defects of the finger.

2016-12-01

There is a paucity of data on the prevalence of multifocal primary hyperhidrosis and changes in hyperhidrosis severity over time. The goal of this study was to better understand multifocal primary hyperhidrosis, prevalence and distribution of hyperhidrosis by focal site, age of onset of symptoms by focal area, and change in hyperhidrosis severity over time and with seasons. The International Hyperhidrosis Society, through an unrestricted research grant from Revance Therapeutics, conducted an online survey of registered visitors to its Web site. Participants identified as having "excessive sweating" and opted to participate in the survey (23 questions) after an e-mail invitation. The survey data illustrate that multifocal primary hyperhidrosis is more common than previously believed and that multifocal hyperhidrosis is more common than singular focal hyperhidrosis (81% of patients reported 3 or more focal hyperhidrotic sites). The data also show that sweating symptom severity does not improve with age but stays the same or gets worse and is "bothersome" throughout the year. Recognition of the chronic and multifocal nature of primary hyperhidrosis is useful for treating hyperhidrosis patients long term and illustrates a need for treatments or treatment combinations that are effective for multiple body areas.

Background There is a wide variation in the reported prevalence of primary hyperhidrosis in the literature. Further, it is unknown if primary hyperhidrosis is a lifelong condition, or if demographical factors influence hyperhidrosis prevalence. Objectives This study aims to examine the prevalence of hyperhidrosis in multiple ethnic groups from two ethnically diverse cities and to determine if the prevalence of primary hyperhidrosis changes according to age, gender, ethnicity, body mass index, and geographical locations. Methods In total, 1010 consecutive subjects attending dermatology outpatient clinics in Shanghai Skin Disease Hospital and 1018 subjects in Skin Care Center of Vancouver General Hospital were invited to fill out a questionnaire on their presenting concerns, demographical information, and sweating symptoms. The subjects were then classified to have primary hyperhidrosis using the criteria of International Hyperhidrosis Society, late-onset hyperhidrosis, or no-hyperhidrosis. The prevalence of primary HH and late-onset HH was calculated for the entire study population and in subgroups stratified according to age of examination, sex, ethnicity, presenting diagnosis, body mass index, and specific study cities. Multivariate logistic regression analyses were performed to assess the impact of these factors on HH prevalence. Results The prevalence of primary hyperhidrosis is very similar in Shanghai and in Vancouver, at 14.5% and 12.3% respectively. In addition, 4.0% of subjects in Shanghai and 4.4% subjects in Vancouver suffer from late-onset HH. Primary HH has highest prevalence in those younger than 30 years of age, decreasing dramatically in later years. Caucasian subjects are at least 2.5 times more likely to develop axillary hyperhidrosis compared to Chinese subjects. Obesity does not have much influence on primary HH presentation, although it does increase significantly the development of late-onset HH. Finally, there is no major difference of

Doing repetitive push-ups is among the most common exercise for the upper body and shoulder stabiliser muscle strength training. However, adverse effects such as neck pain, back pain, palmar pain and wrist pain have been reported. To date, to our knowledge, palmar pressure when performing push-ups has not been previously reported. We hypothesised that various hand positions during push-ups may provide different palmar pressures. Bilateral palmar pressures were recorded in ten individual volunteers. All the subjects were set up for doing push-ups in five positions of the hand. Peak palmar pressure was recorded by Emed pressure platform system (Novel GmBH, Munich, Germany). The palm was divided into the following five anatomic regions, viz. thenar, lunate, hypothenar, metacarpals and fingers. Statistical comparison between the five positions of the hand was analysed using the analysis of variance test. A distribution of the mean peak pressure of the lunate and hypothenar areas were relatively higher than the other areas in both standby and full-elbow flexion positions. At the palmar position 30 cm wider than the shoulder width, the palmar pressure revealed significantly higher peak pressure in the lunate area in the standby and fully-flexed elbow positions (p-value is less than 0.05). At the palmar position 10 cm narrower than the shoulder width, palmar pressure showed significantly higher peak pressure in the hypothenar area only in the fully-flexed elbow position. The information regarding palmar pressures while performing push-ups in different hand positions may be used as a guideline for exercise modification, especially in injured athletes.

Hyperhidrosis is defined as excessive sweating which can be primary or secondary. Data about the prevalence of primary hyperhidrosis are scarce for northern Europe. Our aim was to investigate the prevalence of hyperhidrosis focusing on its primary form and describe the quality of life impairments for the affected individuals. Five thousand random individuals aged 18-60 years in Sweden were investigated. The individuals' addresses were obtained from Statens personadressregister, SPAR, which includes all persons who are registered as resident in Sweden. A validated questionnaire regarding hyperhidrosis including the Hyperhidrosis Disease Severity Scale (HDSS) and 36-item Short Form (SF-36) health survey was sent to each individual. The participants were asked to return the coded questionnaire within 1 week. A total of 1,353 individuals (564 male, 747 female and 42 with unspecified gender) with a mean age of 43.1 ± 11.2 years responded. The prevalence of primary hyperhidrosis was 5.5%, and severe primary hyperhidrosis (HDSS 3-4 points) occurred in 1.4%. Secondary hyperhidrosis was observed in 14.8% of the participants. Our SF-36 results showed that secondary hyperhidrosis causes a significant (p < 0.001) impairment of both mental and physical abilities while primary hyperhidrosis impairs primarily the mental health (p < 0.001). Hyperhidrosis affects individuals in adolescence as a focal form while occurring as a generalised form with increasing age. Further, the prevalence of primary hyperhidrosis described in our study is comparable to other studies from the western hemisphere. While secondary, generalised hyperhidrosis impairs both physical and mental aspects of life, primary hyperhidrosis, with the exception of severe cases, mainly affects the mental health. © 2016 S.

Does surgical sympathectomy improve clinical outcomes in patients with refractory angina pectoris?

PubMed

Holland, Luke C; Navaratnarajah, Manoraj; Taggart, David P

2016-04-01

A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was: In patients with angina pectoris refractory to medical therapy, does surgical sympathectomy improve clinical outcomes? A total of 528 papers were identified using the search protocol described, of which 6 represented the best evidence to answer the clinical question. There were 5 case series and 1 prospective cohort study. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. All 5 of the case series demonstrated an improvement in symptoms, exercise tolerance or quality of life in patients undergoing surgical sympathectomy. An early case series investigating an open approach had a high morbidity and mortality rate, but the 4 other series used a minimally invasive technique and had low morbidity and zero perioperative mortality rates. The cohort study compared surgical sympathectomy with transmyocardial laser revascularization (TMR) and concluded TMR to be superior. However, this study looked only at unilateral sympathectomy, whereas all 5 case series focused on bilateral surgery. We conclude that the best currently available evidence does suggest that patients report an improvement in their symptoms and quality of life following surgical sympathectomy, but the low level of this evidence does not allow for a statistically proved recommendation. © The Author 2016.

2016-12-01

Hyperhidrosis is very common and has a considerable impact on patients' quality of life. While oral oxybutynin is associated with good response rates, adverse effects are common and frequently cause patients to stop treatment. Following the recent launch of oxybutynin in a transdermal patch formulation in Spain, we undertook a preliminary study to assess treatment response and adverse effects in patients with hyperhidrosis. This prospective study of 25 patients treated twice weekly with transdermal oxybutynin patches over 10 weeks assessed treatment response on 2 subjective scales: the Hyperhidrosis Disease Severity Scale (HDSS) and a visual analog scale (VAS) for sweating. Sixty percent of patients showed an improvement in HDSS scores. VAS scores improved in all cases, and 68% of patients achieved a reduction of 3 points or more. Just 2 patients (8%) experienced treatment-related adverse effects (irritant dermatitis at the patch application site in both cases). Although our results are based on a small sample, they suggest that transdermal oxybutynin could be a useful option for the treatment of hyperhidrosis and that it has an excellent safety and tolerability profile.

Proper billing and coding are essential to document the diagnosis of hyperhidrosis and to assure proper reimbursement for treatment. Providers should become familiar with the payment policies of local health plans to streamline the preauthorization process that is often needed for many treatments commonly used for hyperhidrosis. Having a preprinted letter of medical necessity and patient intake forms that record the necessary historical information about the disease, previous treatments, and other pertinent information will help increase the speed of the office flow.

The purpose of this study was to evaluate the efficacy and tolerability of aluminium chloride gel for treatment of axillary hyperhidrosis. A total of 20 patients aged 22-38 (mean age: 26.9+/-4.3) with idiopathic axillary hyperhidrosis were included and treated with an antiperspirant (Sweat-off, Sweat-off GmbH, Hügelsheim). Study duration was 42 days. Treatment efficacy was evaluated clinically, as well as by starch-iodine test, gravimetric analysis and evaluation of the skin surface pH. After treatment there was a significant clinical improvement accompanied by significant qualitative and quantitative reduction of sweat as well as a significant reduction of skin surface pH. Except for slight skin irritation in 6 patients, there were no other side effects. Patient satisfaction improved markedly during the study. Treatment of axillary hyperhidrosis with aluminium chloride is an effective, safe and inexpensive treatment modality.

Segmental hyperhidrosis as a manifestation of spinal and paraspinal disease.

PubMed

Schulz, V; Ward, D; Moulin, D E

1998-11-01

Segmental hyperhidrosis is an uncommon finding which is usually associated with irritation or infiltration of pre-ganglionic sympathetic fibres or the sympathetic chain. We report two cases of segmental hyperhidrosis with striking clinical features. In one case, a mesothelioma produced ipsilateral simultaneous underactivity and overactivity of sympathetic outflow and in the other case a thoracic central disc herniation was probably responsible for a band of sweating which clearly extended beyond the segmental level of injury. Segmental hyperhidrosis should trigger a search for structural disease in the spinal and paraspinal region.

An understanding of the daily life impacts of hyperhidrosis and how patients deal with them, based on qualitative research, is lacking. This study investigated the impact of hyperhidrosis on the daily life of patients using a mix of qualitative research methods. Participants were recruited through hyperhidrosis patient support groups such as the Hyperhidrosis Support Group UK. Data were collected using focus groups, interviews and online surveys. A grounded theory approach was used in the analysis of data transcripts. Data were collected from 71 participants, out of an initial 100 individuals recruited. Seventeen major themes capturing the impacts of hyperhidrosis were identified; these covered all areas of life including daily life, psychological well-being, social life, professional /school life, dealing with hyperhidrosis, unmet health care needs and physical impact. Psychosocial impacts are central to the overall impacts of hyperhidrosis, cutting across and underlying the limitations experienced in other areas of life.

To systematically analyse the literature on the use of the microwave-based device for subdermal thermolysis of the axilla and its efficacy for the treatment of axillary hyperhidrosis. A systematic review was conducted using PubMed, Embase, SCOPUS and Cochrane databases on 2 June 2016. The inclusion criteria including: (1) studies with human subjects, (2) full-text articles published in English, (3) a microwave-based device used to treat axillary hyperhidrosis and (4) trials that precisely evaluated axillary hyperhidrosis. Exclusion criteria were the following: (1) studies that did not fit the inclusion criteria mentioned above and (2) case reports and reviews. We reviewed five clinical trials and 189 patients, all of which were published between 2012 and 2016. There was one randomized controlled trial, one retrospective study and the remainder were prospective studies. Although all of the studies were conducted with a small sample size, the results indicated that microwave-based device treatment of axillary hyperhidrosis had long-term efficacy with mild adverse effects. In addition, most patients were satisfied with the outcomes in these studies. Microwave-based device treatment may be an effective alternative treatment for axillary hyperhidrosis. However, further investigation is necessary to determine its long-term efficacy and safety.

Hyperhidrosis is a reason for treatment by many specialists in medicine, such as dermatologists, family medicine doctors, surgeons and also psychiatrists. Hyperhidrosis causes considerable distress and disability. Despite the fact that the condition has been known for thousands of years, it is yet unclear whether excessive sweating derives from emotional" activation of the central nervous system, whether the emotional symptoms evolve due to local dysfunction of the sweat glands, or a combination of the two problems. In this article, we will present two conditions: hyperhidrosis and Social Anxiety Disorder, a mental condition with anxiety and avoidanrce in social settings that is frequently accompanied by sweating. We will discuss the similarities and differences between these disorders and the various treatments available for these conditions. Research shows that social anxiety does not explain hyperhidrosis, but that excessive sweating reduces the threshold for social anxiety. Among people with hyperhidrosis, the functional disability and the emotional problems are mediated by the social anxiety. We propose treating the symptoms of hyperhidrosis and social anxiety disorder in combination in order to achieve maximal improvement in these patients.

Hyperhidrosis is an embarrassing condition that may interfere with routine activities, cause emotional distress, and disturb both professional and social lives of patients. Objective examination is variable and unreliable, so efforts have been made in the last 15 years to substantiate the limitations of these patients, especially in primary focal hyperhidrosis. Almost all therapeutic studies use standardized or self-designed instruments to evaluate the impact of the disease on quality of life and the improvement achieved by treatment. This article gives an overview of the difficulties with which patients with hyperhidrosis are confronted and of research investigating the restrictions. Copyright © 2014 Elsevier Inc.

Oral oxybutynin for treating hyperhidrosis is effective and safe. Its side-effects are mild but frequent so we consider whether transdermal oxybutynin (considered to have a better side-effect profile) could be an alternative for treating hyperhidrosis. During 2015, a prospective study was conducted. Epidemiological variables, effectiveness (using the Hyperhidrosis Disease Severity Scale) and tolerance to transdermal oxybutynin were compiled concerning two different groups (patients previously treated or untreated with oral oxybutynin), at baseline, and at 3 and 12 months. Seven previously treated and six previously untreated patients were included. Five patients in the first group discontinued the treatment within 3 months. Of the two remaining patients, one reported ineffectiveness and the other obtained an excellent response but discontinued due to local irritation. Among the untreated patients, two showed no response and four experienced improvement (three with "partial response" and one with "excellent response"). All patients discontinued treatment within 12 months. No major adverse effects were observed. The absence of active metabolites after transdermal oxybutynin could result in less effectiveness than oral oxybutynin, although it is usually well tolerated. In conclusion, transdermal oxybutynin could have low effectiveness for the treatment of hyperhidrosis in patients following intolerance to oral oxybutynin but could provide good results in patients who have never tried systemic drugs. © 2017 Japanese Dermatological Association.

Focal hyperhidrosis can have a substantial influence on the professional, physical, emotional and social life of those affected. This becomes clear when the results of quality of life studies and Health Service Research studies are reviewed, e.g. affected patients were prepared to contribute additional money for treatment of hyperhidrosis. The systemic therapy of focal hyperhidrosis with oral anticholinergic agents is a quite economical treatment strategy. These products can be administered continuously or sporadically. However, only good clinical date for the continous treatment exists. Focal hyperhidrosis is a disease which requires our full attention. It should be discussed whether e.g. QoL questionnaires should be used routinelly.

Current published estimates of the prevalence of hyperhidrosis in the United States are outdated and underestimate the true prevalence of the condition. The objectives of this study are to provide an updated estimate of the prevalence of hyperhidrosis in the US population and to further assess the severity and impact of sweating on those affected by the condition. For the purposes of obtaining prevalence, a nationally representative sample of 8160 individuals were selected using an online panel, and information as to whether or not they experience hyperhidrosis was obtained. The 393 individuals (210 female, 244 non-Hispanic white, 27 black, mean age 40.3, SE 0.64) who indicated that they have hyperhidrosis were asked further questions, including body areas impacted, severity of symptoms, age of onset, and socioemotional impact of the condition. Current results estimate the prevalence of hyperhidrosis at 4.8 %, which represents approximately 15.3 million people in the United States. Of these, 70 % report severe excessive sweating in at least one body area. In spite of this, only 51 % have discussed their excessive sweating with a healthcare professional. The main reasons are a belief that hyperhidrosis is not a medical condition and that no treatment options exist. The current study's findings with regard to age of onset and prevalence by body area generally align with the previous research. However, current findings suggest that the severity and prevalence are both higher than previously thought, indicating a need for greater awareness of the condition and its associated treatment options among medical professionals.

At present, primary hyperhidrosis is the main indication for sympathectomy. For upper thoracic sympathetic ablation, excision of the second thoracic ganglion alone or with the first and/or third ganglia was the standard during the open surgery era. With the advent of thoracoscopy, modifications related to the level, extent, and type of ablation were proposed to attenuate compensatory hyperhidrosis. The ideal operation for sympathetic denervation of the face and upper limbs remain to be defined. Controlled double-blind studies with quantitave measurements of sweat production are required.

In Europe often no clear distinction is made between deodorant and antiperspirant. Particularly in Germany, the labeling "deo" is used for both. Only antiperspirants are capable of influencing the activity of eccrine sweat glands. In the treatment of focal hyperhidrosis, the use of aluminum chloride solutions represents the first choice. The efficacy is well documented in a variety of studies. Subjective side effects include pruritus and - less often - irritant dermatitis, which can be treated symptomatically and usually does not require discontinuation of the treatment. Rare variants of focal hyperhidrosis like auriculotemporal syndrome, Ross syndrome and nevus sudoriferus also are suitable for treatment with topical aluminum chloride hexahydrate solutions.

Elevated Social Stress Levels and Depressive Symptoms in Primary Hyperhidrosis

2014-01-01

Primary hyperhidrosis is defined as excessive sweating of certain body areas without physiological reasons. Hyperhidrotic individuals report a high psychological strain and an impairment of their quality of life. Thus, the aim of the study is to investigate the relation between hyperhidrosis and different psychological as well as physiological aspects of chronic stress as a co-factor for the etiology of depression. In this study, forty hyperhidrotic subjects were compared to forty age- and sex-matched healthy control subjects. The Trier Inventory of Chronic Stress (‘Trierer Inventar zum chronischen Stress’: TICS), the Beck Depression Inventory (BDI-II) and the Screening for Somatoform Disorders (SOMS-2) were used to examine the correlation between primary hyperhidrosis and stress as well as accompanying depressive and somatic symptoms. The cortisol awakening response of each subject was analyzed as a physiological stress correlate. In hyperhidrotics, we found a significant lack of social recognition as well as significantly more depressive symptoms compared to the control subjects. A subgroup of patients with axillary hyperhidrosis had the highest impact on these increased issues of chronic stress, pointing to a higher embarrassment in these subjects. Especially in social situations, hyperhidrotics showed higher stress levels, whereby a vicious circle of stress and sweating is triggered. However, the cortisol awakening response did not significantly differ between hyperhidrotics and controls. Moreover, affected persons suffer from more depressive symptoms, which may be caused by feelings of shame and a lack of self-confidence. This initial study provides an impetus for further investigation to reveal a causative relationship between hyperhidrosis and its psychological concomitants. PMID:24647796

Hyperhidrosis, or abnormally increased sweating, is a condition that may have a primary or secondary cause. Usually medication- induced secondary hyperhidrosis manifests with generalized, rather than focal sweating. We report a 32-year-old woman with a history of palmoplantar hyperhidrosis for 15 years who presented for treatment and was prescribed oral glycopyrrolate. One month later, the palmoplantar hyperhidrosis had resolved, but she developed new persistent craniofacial sweating. After an unsuccessful trial of clonidine, oxybutynin resolved the craniofacial hyperhidrosis. To our knowledge, this is the first case of compensatory hyperhidrosis secondary to glycopyrrolate reported in the literature. The case highlights the importance of reviewing medication changes that correlate with new onset or changing hyperhidrosis. It also demonstrates a rare drug adverse effect with successful treatment.

Hyperhidrosis is a disorder that can impair quality of life. Localized treatments may be cumbersome and ineffective, and no systemic treatments have proven to be significantly beneficial. To evaluate the effectiveness and tolerance of low-dose oxybutynin for hyperhidrosis. We conducted a prospective, randomized, placebo-controlled trial. From June 2013 to January 2014, 62 patients with localized or generalized hyperhidrosis were enrolled. Oxybutynin was started at a dose of 2·5 mg per day and increased gradually to 7·5 mg per day. The primary outcome was defined as improvement of at least one point on the Hyperhidrosis Disease Severity Scale (HDSS). Dermatology Life Quality Index (DLQI) and tolerance were also reported. Most patients (83%) in our study had generalized hyperhidrosis. Oxybutynin was superior to placebo in improving the HDSS: 60% of patients treated with oxybutynin, compared with 27% of patients treated with placebo, improved at least one point on the HDSS (P = 0·009). The mean improvement in quality of life measured by DLQI was significantly better in the oxybutynin arm (6·9) than in the placebo arm (2·3). The most frequent side-effect was dry mouth, which was observed in 43% of the patients in the oxybutynin arm, compared with 11% in the placebo arm. Treatment with low-dose oxybutynin is effective in reducing symptoms of hyperhidrosis in generalized or localized forms. Side-effects were frequent but minor and mainly involved dry mouth. © 2015 British Association of Dermatologists.

Hyperhidrosis has recently been described as a novel adverse effect of laser-assisted hair removal in the axillary area. Inguinal Hyperhidrosis (IH) is a localized and, typically, a primary form of hyperhidrosis affecting the groin area in individuals before age 25. IH has been reported in the literature after traumas and as a dysfunction of the central sympathetic nervous system. To the best of our knowledge, IH has never been reported as secondary to laser-assisted hair removal. Herein, we report three cases of IH following depilatory laser of the inguinal zone. Three female patients with no relevant medical history presented with the complaint of excessive sweating in the inguinal area after undergoing full bikini depilatory laser sessions. Although never described before, depilatory laser seems to trigger the occurrence of hyperhidrosis in the inguinal zone.

Palmar lunate dislocation as the end stage of a perilunate dislocation is a very uncommon injury. Having treated 19,534 hospitalized patients between 1 January 1986 and 1 October 2001 the diagnosis was recorded in four male trauma patients (33, 36, 37 and 62 years old). Among the operatively treated carpal dislocations and carpal fracture dislocations those of the lunate were seen in five per cent. The dislocation was caused in by an acute hyperextension injury resulting of falls from heights in three cases, and of a motorcycle accident in a further case. In two of these cases a complete palmar lunate dislocation was analysed that were produced by fall from seven meters heights of a young craftsman and by accident of a motorcyclist. First using a longitudinal palmar approach in both cases a revision of the hemorrhagic carpal canal was performed urgently, the largely denuded lunate was reduced and the repair of identified ligamentous structures was performed by means of sutures respectively suture anchors. Reduction was stabilized with Kirschner wires. Afterwards performed computed tomography identified the result of reduction and associated defects (subluxation distal radioulnar joint). In one patient a soft tissue infection prevented the dorsal ligamentous repair. In spite of a consequent after-treatment and a good functional result a scapho-lunate dissociation was proved. An avascular defect of the lunate could be excluded by magnetic resonance imaging. In case of a secondary performed dorsal repair a persisting carpal stabilization with a satisfactory functional result could achieved. At second hand an advanced carpal collapse was proved. If reduction cannot be achieved by closed manipulation or a loss of reduction is shown, open reduction is indicated first by a palmar approach. An additional dorsal ligamentous repair seems to be necessary. Transfixation by Kirschner wires and suture anchors stabilize the restored anatomic relationships. Wrist immobilization in

Digital ischemia is commonly found in patients with scleroderma and has been shown to respond to peripheral digital sympathectomy. While favorable long- and intermediate-term results have been documented in the literature, minimal objective data are available and the mechanism of surgical sympathectomy has not been entirely elucidated. Patients with digital ischemia secondary to Raynaud's phenomenon that had undergone peripheral sympathectomy surgery between 2001 and 2009 were identified and contacted for participation. Radial artery Doppler ultrasound studies were performed and compared to those done at the time of their sympathectomy. Of 11 patients treated over a 9-year period, only two patients were available for detailed follow-up analysis. Four patients were deceased, and two were lost to follow-up. Four of the five remaining patients reported excellent use of the hand and no significant episodes of digital ischemia. Of the two patients studied, functional results were favorable and pain was markedly improved despite worsening of the digital flow resistance over time. We conclude that peripheral digital sympathectomy may provide favorable long-term results in patients with digital ischemia from autoimmune causes, although this intervention should be considered in the early stages once ischemic symptoms manifest. Interestingly, Doppler data did not appear to correlate with functional status and symptom severity in these two patients. Further research, particularly prospective studies, is warranted to guide clinical decisions in this patient population.

Clinical Evaluation of a Microwave Device for Treating Axillary Hyperhidrosis

2012-01-01

Background A third-generation microwave-based device has been developed to treat axillary hyperhidrosis by selectively heating the interface between the skin and underlying fat where the sweat glands reside. Materials and Methods Thirty-one (31) adults with primary axillary hyperhidrosis were enrolled. All subjects had one to three procedure sessions over a 6-month period to treat both axillae fully. Efficacy was assessed using the Hyperhidrosis Disease Severity Scale (HDSS), gravimetric weight of sweat, and the Dermatologic Life Quality Index (DLQI), a dermatology-specific quality-of-life scale. Subject safety was assessed at each visit. Subjects were followed for 12 months after all procedure sessions were complete. Results At the 12-month follow-up visit, 90.3% had HDSS scores of 1 or 2, 90.3% had at least a 50% reduction in axillary sweat from baseline, and 85.2% had a reduction of at least 5 points on the DLQI. All subjects experienced transient effects in the treatment area such as swelling, discomfort, and numbness. The most common adverse event (12 subjects) was the presence of altered sensation in the skin of the arm that resolved in all subjects. Conclusion The device tested provided efficacious and durable treatment for axillary hyperhidrosis. PMID:22452511

The reaction to body and finger cooling was recorded in seven patients with relapse of primary Raynaud's phenomenon after sufficiently performed bilateral upper thoracic sympathectomy and for comparison in eight young women with primary Raynaud's phenomenon as well as in seven normal women. The forearm venous concentration of noradrenaline was lower and adrenaline concentration higher in the sympathectomized patients than in the other groups (p less than 0,05). Noradrenaline showed a significant increase during body cooling in normals and primary Raynaud's (p less than 0,05). There was no significant correlation between the vasoconstrictor response to cooling of a finger and the noradrenaline concentration probably due to the fact that skin vasoconstriction impeded release of noradrenaline from the skin. The relapse of Raynaud's phenomenon after surgically sufficient sympathectomy could not be treated by reserpine or alfa-adrenergic receptor blockers in two patients in whom this was tried.

ABSTRACT Objective: Our aim was to analyze the effectiveness of oxybutynin for hyperhidrosis treatment in patients over 40 years. Methods: Eighty-seven patients aged over 40 years were divided into two groups. One group consisted of 48 (55.2%) patients aged between 40 and 49 years, and another was composed of 39 (44.8%) patients aged over 50 years (50 to 74 years). A comparative analysis of Quality of Life and level of hyperhidrosis between the groups was carried out 6 weeks after a protocol treatment with oxybutynin. A validated clinical questionnaire was used for evaluation. Results: In the younger age group, 75% of patients referred a “partial” or “great” improvement in level of hyperhidrosis after treatment. This number was particularly impressive in patients over 50 years, in which 87.2% of the cases demonstrated similar levels of improvement. Over 77% of patients in both groups demonstrated improvement in Quality of Life. Excellent outcomes were observed in older patients, in which 87.1% of patients presented “slightly better” (41%) or “much better” (46.1%) improvement. Conclusion: Patients aged over 40 years with hyperhidrosis presented excellent results after oxybutynin treatment. These outcomes were particularly impressive in the age group over 50 years, in which most patients had significant improvement in Quality of Life and in level of hyperhidrosis. PMID:24728245

Summary Sweating is an important mechanism for ensuring constant thermoregulation, but hyperhidrosis may be disturbing. We present five cases of hemifacial hyperhidrosis as a compensatory response to an/hypohidrosis caused by cervical disc herniation. All the patients complained of hemifacial hyperhidrosis, without anisocoria or blepharoptosis. Sweat function testing and thermography confirmed hyperhidrosis of hemifacial and adjacent areas. Neck MRI showed cervical disc herniation. Three of the patients had lateral compression with well-demarcated hypohidrosis below the hyperhidrosis on the same side as the cervical lesion. The rest had paramedian compression with poorly demarcated hyperhidrosis and hypohidrosis on the contralateral side. Although MRI showed no intraspinal pathological signal intensity, lateral dural compression might influence the circulation to the sudomotor pathway, and paramedian compression might influence the ipsilateral sulcal artery, which perfuses the sympathetic descending pathway and the intermediolateral nucleus. Sweat function testing and thermography should be performed to determine the focus of the hemifacial hyperhidrosis, and the myelopathy should be investigated on both sides. PMID:25014051

Anti-dopamine beta-hydroxylase immunotoxin (DHIT) is an antibody-targeted noradrenergic lesioning tool comprised of a monoclonal antibody against the noradrenergic enzyme, dopamine beta-hydroxylase, conjugated to saporin, a ribosome-inactivating protein. Noradrenergic-neuron specificity and completeness and functionality of sympathectomy were assessed. Adult, male Sprague-Dawley rats were given 28.5, 85.7, 142 or 285 micrograms/kg DHIT i.v. Three days after injection, a 6% to 73% decrease in the neurons was found in the superior cervical ganglia of the animals. No loss of sensory, nodose and dorsal root ganglia, neurons was observed at the highest dose of DHIT. In contrast, the immunotoxin, 192-saporin (142 micrograms/kg), lesioned all three ganglia. To assess the sympathectomy, 2 wk after treatment (285 micrograms/kg), rats were anesthetized with urethane (1 g/kg) and cannulated in the femoral artery and vein. DHIT-treated animals' basal systolic blood pressure and heart rate were significantly lower than controls. Basal plasma norepinephrine levels were 41% lower in DHIT-treated animals than controls. Tyramine-stimulated release of norepinephrine in DHIT-treated rats was 27% of controls. Plasma epinephrine levels of DHIT animals were not reduced. DHIT-treated animals exhibited a 2-fold hypersensitivity to the alpha-adrenergic agonist phenylephrine. We conclude that DHIT selectively delivered saporin to noradrenergic neurons resulting in destruction of these neurons. Anti-dopamine beta-hydroxylase immunotoxin administration produces a rapid, irreversible sympathectomy.

Soft tissue defects on the lateral borders of the digits are difficult to reconstruct using local or local-regional flaps. We describe a "palmar pivot flap" to resurface an adjacent defect on the palmar-lateral aspect of the digit. The surgical technique is described. This flap is an axial pattern flap based on the subcutaneous transverse branches of the digital artery. The flap is pivoted up to 90 degrees on the neurovascular bundle in its base, into an adjacent defect. The flap can be raised from either the proximal or the middle phalangeal segments. It can cover defects sited from the level of the proximal interphalangeal joint up to the fingertip. The donor defect is limited to the same digit and is covered with a full-thickness skin graft. We have used this flap on 3 patients with defects at the middle phalangeal segment, the distal interphalangeal joint, and the fingertip. All healed primarily. One patient had a mild flexion contracture of the proximal interphalangeal joint, whereas the other 2 had no complications. The patients with distal interphalangeal joint and fingertip defects had excellent sensation in the flap (2-point discrimination of 5-6 mm). The palmar pivot flap is useful for resurfacing otherwise difficult defects on the lateral borders of the digits around and distal to the proximal interphalangeal joint, including those at the fingertip. It provides sensate, glabrous skin. The donor defect is on the same digit and is well hidden, producing an aesthetic and functional reconstruction.

Although many treatments are available to address hyperhidrosis, the results are not always satisfactory. The aim of the study was to assess the effectiveness, optimal dosage regimen and long-term safety of oral oxybutynin in the treatment of hyperhidrosis. A retrospective review was performed on 110 patients who underwent treatment for hyperhidrosis between February 2007 and December 2013. Their response to treatment was evaluated using the hyperhidrosis disease severity scale at baseline, 3 and 12 months. Additionally, the safety and effectiveness of different up-dosing and fixed-dose regimens were compared. After 3 months of treatment, 87 of the 110 patients (79%) had responded (63%), which was considered excellent. After 12 months, 63 patients (62%) continued to respond, and the response was considered excellent in 50%. Nine patients were lost to follow up between month 3 and 12. In total, 77 and 70% of the patients who responded at 3 and 12 months, respectively, reported mild adverse events. No serious adverse events were observed. Treatment adherence was significantly higher among patients following the individualised up-dosing regimen. Oral oxybutynin may be an effective and safe option for the long-term treatment of hyperhidrosis. To improve treatment adherence, oxybutynin dosing regimens should be individualised on the basis of the patient's tolerance and response. © 2016 The Australasian College of Dermatologists.

Hyperhidrosis of the residual limb is a common condition affecting patients with amputations. The iodine-starch test is used by dermatologists to identify focal areas of hyperhidrosis before treatment with botulinum toxin. Here, we describe a case of a patient with a transtibial amputation with moderate-to-severe hyperhidrosis who received intradermal botulinum toxin injections to treat residual limb hyperhidrosis, with particular emphasis given to the utility of the iodine-starch test in managing this common condition. The iodine-starch test successfully identified hyperhidrotic areas before treatment as well as confirmed the physiologic anhidrotic effect of the botulinum toxin treatment. V.

The association of osmidrosis and hyperhidrosis often causes emotional and social problems that may impair the patients' quality of life. The purpose of our study was to analyze the therapeutic results of oxybutynin and topical agents in 89 patients with both osmidrosis and hyperhidrosis. We conducted an observational study at two specialized centers of hyperhidrosis between April 2007 and August 2013. Eighty-nine (89) patients with both osmidrosis and hyperhidrosis were treated with oxybutynin and topical agents. Patients were evaluated before treatment and at 3 and 6 weeks after treatment started, by using the Quality of Life Questionnaire and the Sweating Evolution Scale. Before treatment, 98% of the patients presented with poor or very poor quality of life. After six weeks of treatment, 70% stated their quality of life as being slightly better or much better (p<0.001) and nearly 70% of the patients experienced a moderate or great improvement in sweating and malodor. Improvement in osmidrosis was significantly greater when the axillary region was the first most disturbing site of hyperhidrosis. There was a significant improvement in quality of life and a reduction in sweating and malodor after six weeks of treatment with topical agents and oxybutynin in patients with both hyperhidrosis and osmidrosis. Therefore, clinical treatment should be considered before invasive techniques.

Raynaud's syndrome is a known complication of cold injuries. Stress, smoking and metabolic diseases may further aggravate the disease course. The purpose of this study was to determine the efficacy of Cervico-thoracic sympathectomy as compared to conservative management in severe Raynaud's syndrome after frostbite. This non-randomized controlled trial was conducted at Railway Hospital, Rawalpindi and Islamic International Medical Complex, Islamabad between January 1999 and June 2006. All patients sustained severe cold trauma in the mountain ridges of Himalayas in Kashmir. In all cases, an informed consent was obtained from patients and families. All operations performed were free of charges. Out of the total 48 patients who developed incapacitating Raynaud's syndrome of the upper limbs after frost bite, 17 patients underwent thoracic sympathectomy through anterior supraclavicular route. Remaining 31 patients were treated conservatively and were placed in the control group. Data was collected on pre-designed proforma and assessed using SPSS (version 11). Chi-square test was applied to assess the effectiveness of the two treatment modalities. All operated cases initially showed improvement in symptoms and incapacitation. Among sympathectomised patients, 11 patients became symptom free and 3 patients showed mild but improved symptoms. Two patients after initial transient improvement developed incapacitating symptoms requiring further treatment, one patient developed gangrene ofdistal phalanx nine month after sympathectomy requiring amputation of the finger. Frequency of attacks and duration between the attacks reduced in all operated patients of cervical sympathectomy (p < 0.05) as compared to conservative management. Cervical sympathectomy is a very effective modality of treatment in patients having severe Raynaud's disease of upper limbs secondary to frost bite.

[Purpose] The purpose of the present study was to determine the effects of changes in palmar width on the muscle activities of the shoulder and truncus muscles during push-up exercise. [Subjects] Twelve healthy adult males participated in this study as subjects. [Methods] Push-up exercises were performed with three different palmar width in narrow (50%), neutral (100%), and wide positions (150%). We measured the muscle activities of the deltoideus p. acromialis, pectoralis minor, pectoralis major, serratus anterior, biceps brachii, triceps brachii, latissimus dorsi, and infraspinatus. [Results] Pectoralis minor, triceps brachii, and infraspinatus muscle activities were greater during push-ups performed with the 50% palmar width compared with the other palmar widths. Pectoralis major muscle activity was greater during push-ups performed with the 50% and 100% palmar widths compared with the 150% palmar width. Serratus anterior muscle activity was greater during push-ups performed with the 150% palmar width compared with the other palmar widths. [Conclusion] These results are expected to serve as reference materials for push-up exercise applications in training programs for truncus muscle strengthening or rehabilitation programs for scapula patients.

Oxybutynin is an anticholinergic drug with an emerging role in the treatment of hyperhidrosis. Several recent studies have documented that it is effective both in focal and generalized hyperhidrosis and shows universally good response among different groups of patients regardless of age, gender, and weight. The most common adverse event is dry mouth reported by almost all patients treated. The way this might affect long-term compliance and tolerability should be better investigated in the future.

Peripheral arterial disease (PAD) is a common circulatory problem that can lead to reduced blood flow to the limbs, which may result in critical limb ischaemia (CLI), a painful manifestation that occurs when a person is at rest. The mainstay of treatment for CLI is surgical or endovascular repair. However, when these means of treatment are not suitable, due to anatomical reasons or comorbidities, treatment for pain is limited. Lumbar sympathectomy and prostanoids have both been shown to reduce pain from CLI in people who suffer from non-reconstructable PAD, but there is currently insufficient evidence to determine if one treatment is superior. Due to the severity of the rest pain caused by CLI, and its impact on quality of life, it is important that people are receiving the best pain relief treatment available, therefore interest in this area of research is high. To compare the efficacy of lumbar sympathectomy with prostanoid infusion in improving symptoms and function and avoiding amputation in people with critical limb ischaemia (CLI) due to non-reconstructable peripheral arterial disease (PAD). The Cochrane Vascular Information Specialist (CIS) searched the Specialised Register (last searched 29 March 2017) and CENTRAL (2017, Issue 2). The CIS also searched clinical trials databases for ongoing or unpublished studies. Randomised controlled trials (RCTs), with parallel treatment groups, that compared lumbar sympathectomy (surgical or chemical) with prostanoids (any type and dosage) in people with CLI due to non-reconstructable PAD. Three review authors independently selected trials, extracted data and assessed risk of bias. Any disagreements were resolved by discussion. We performed fixed-effect model meta-analyses, when there was no overt sign of heterogeneity, with risk ratios (RRs) and 95% confidence intervals (CIs). We graded the quality of evidence according to GRADE. We included a single study in this review comparing lumbar sympathectomy with prostanoids

Hyperhidrosis o`ccurs when the body produces sweat beyond what is essential to maintain thermal homeostasis. The condition tends to occur in areas marked by high-eccrine density such as the axillae, palms, and soles and less commonly in the craniofacial area. The current standard of care is topical aluminum chloride hexahydrate antiperspirant (10-20%), but other treatments such as anticholinergics, clonidine, propranolol, antiadrenergics, injections with attenuated botulinum toxin, microwave technology, and surgery have been therapeutically implicated as well. Yet, many of these treatments have limited efficacy, systemic side effects, and may be linked with significant surgical morbidity, creating need for the development of new and effective therapies for controlling excessive sweating. In this literature review, we examined the use of lasers, particularly the Neodynium:Yttrium-Aluminum-Garnet (Nd:YAG) and diode lasers, in treating hyperhidrosis. Due to its demonstrated effectiveness and limited side effect profile, our review suggests that Nd:YAG laser may be a promising treatment modality for hyperhidrosis. Nevertheless, additional large, randomized controlled trials are necessary to confirm the safety and efficacy of this treatment option.

Clinical differentiation between palmar psoriasis and chronic hand eczema may sometimes be a diagnostic challenge; in such cases histopathological analysis helps to differentiate the two conditions. In the present study, palmar psoriasis and chronic hand eczema were investigated using dermoscopy and the significance of specific dermoscopic features was assessed in order to improve their non-invasive differentiation. Ten patients with biopsy-proven palmar psoriasis and 11 patients with biopsy-proven chronic hand eczema were included in the study. We found that the presence of diffuse white scales was significant in palmar psoriasis whereas the presence of yellowish scales, brownish-orange dots/globules and yellowish-orange crusts was significant in chronic hand eczema. © 2015 Japanese Dermatological Association.

Aim: The present study was conducted to evaluate the equine palmar tendon by ultrasonography (USG) in standing the position. Materials and Methods: USG of palmar tendons was performed in 40 adult horses using linear transducer having frequency of 10-18 MHz (e-soate, My Lab FIVE) and L52 linear array transducer (Titan, SonoSite) with frequencies ranging from 8 to 10 MHz. Palmar tendon was divided into 7 levels from distal to accessory carpal bone up to ergot in transverse scanning and 3 levels in longitudinal scanning. Results: The USG evaluation was very useful for diagnosis of affections of the conditions such as chronic bowed tendon, suspensory ligament desmitis, carpal sheath tenosynovitis and digital sheath effusions. The mean cross-sectional area (cm2) of affected tendons was significantly increased in affected than normal tendons. The echogenicity was also found reduced in affected tendons and ligaments along with disorganization of fiber alignment depending on the severity of lesion and injury. Conclusion: USG proved ideal diagnostic tool for diagnosis and post-treatment healing assessment of tendon injuries in horses. PMID:27047074

Palmar and plantar pustulosis elicited by Candida antigen.

Intracutaneous injection of Candida albicans was done on the forearm of 30 patients with palmar and plantar pustulosis. This induced an aggravation of pustular eruptions on the palms and soles in 11 (37%) of the 30 patients. The aggravation occurred only in those patients who had a positive delayed skin reaction to the Candida antigen. It is suggested that a delayed hypersensitivity inflammatory reaction somewhere in the body is attended with an aggravation of palmar plantar pustulosis.

Primary hyperhidrosis is an under-recognized condition in children and adolescents. Iontophoresis is the second line of treatment for palmoplantar hyperhidrosis following topical treatment. The studies evaluating the efficacy of iontophoresis in children are limited. We aimed to investigate the efficacy and reliability of tap water iontophoresis in children with primary hyperhidrosis. Twenty-one patients aged under 18 years, who received iontophoresis for primary palmoplantar hyperhidrosis, were included in the study. In our clinic, tap water iontophoresis was administered at regular intervals, starting with five times per week and decreased to once a week on fifth week. Then maintenance sessions once a week for 6 weeks are recommended. The presence of excessive sweating was scored by visual analogue scale (VAS): "0" as continuation of excessive sweating and "10" as the absence of excessive sweating. The demographic and clinical data were collected from files. Also, patients fulfilled a questionnaire for efficacy on follow-up visit. Nineteen patients completed the whole 21 sessions. The mean VAS score was 5.89 ± 1.49 at the end of the 15th session and 6.36 ± 2.06 at the end of the treatment. Side effects were well tolerated. Only seven patients were still free of excessive sweating on third months after treatment. The mean satisfaction score was 4.95 ± 2.38, as measured by VAS where 0 indicated dissatisfaction and 10 indicated high satisfaction. Tap water iontophoresis is an effective method of treatment for primary palmoplantar and axillary hyperhidrosis in paediatric patients. But there are still unanswered questions about the mechanism of action, ideal session intervals and protocols for maximum efficacy.

Botulinum toxin type A (BTX-A) injections are an effective treatment for controlling hyperhidrosis at sites of amputation. Hyperesthesia associated with amputated limbs is a major barrier to performing this procedure under local anesthesia. To present a novel method for improving local anesthesia with BTX-A injections. Methods & A 29-year-old military veteran with a below-the-knee amputation of his right leg was suffering from amputation site hyperhidrosis, which was impeding his ability to comfortably wear a prosthesis. Prior to presenting to our clinic, the patient received one treatment of BTX-A injections to his amputation stump while under general anesthesia for surgical repair of trauma-related injuries. In our dermatology clinic, we repeated the procedure using topical lidocaine-prilocaine (30 gm total) for local anesthesia. This provided effective relief of hyperhidrosis for 6 months, but the procedure was very painful (9/10 intensity). We repeated the same procedure 6 months later, using ice in addition to topical lidocaine-prilocaine (30 gm) for local anesthesia; this resulted in reduced pain (3/10 intensity) for the patient. We suggest using ice in combination with a topical anesthetic as an effective method for pain control that avoids general anesthesia in treating amputation-associated hyperhidrosis.

Postural orthostatic tachycardia syndrome is characterized by orthostatic intolerance. Orthostasis (or other mild physical stress) triggers a cascade of inappropriate tachycardia, lightheadedness, palpitations, and often fainting. The underlying defect is sympathetic dysregulation of the heart, which receives its sympathetic tone from the cervical and upper thoracic sympathetic ganglia. Primary hyperhidrosis is also thought to be the result of sympathetic dysregulation. We present the case of a patient treated with CT-guided, percutaneous T2 EtOH sympatholysis for craniofacial hyperhidrosis. The patient also suffered from postural orthostatic tachycardia syndrome for many years and was unresponsive to treatment. Immediately after sympatholysis, the patient experienced resolution of both craniofacial hyperhidrosis and postural orthostatic tachycardia syndrome.

OBJECTIVES: Primary hyperhidrosis usually affects the hands, armpits, feet and cranio-facial region. Sweating in other areas is common in secondary hyperhidrosis (after surgery or in specific clinical conditions). Oxybutynin has provided good results and is an alternative for treating hyperhidrosis at common sites. Our aim was to evaluate the efficacy of oxybutynin as a treatment for primary sweating at uncommon sites (e.g., the back and groin). METHODS: This retrospective study analyzed 20 patients (10 females) who received oxybutynin for primary focal hyperhidrosis at uncommon sites. The subjects were evaluated to determine quality of life before beginning oxybutynin and six weeks afterward and they were assigned grades (on a scale from 0 to 10) to measure their improvement at each site of excessive sweating after six weeks and at the last consult. RESULTS: The median follow-up time with oxybutynin was 385 days (133-1526 days). The most common sites were the back (n = 7) and groin (n = 5). After six weeks, the quality of life improved in 85% of the subjects. Dry mouth was very common and was reported by 16 patients, 12 of whom reported moderate/severe dry mouth. Five patients stopped treatment (two: unbearable dry mouth, two: excessive somnolence and one: palpitations). At the last visit, 80% of patients presented with moderate/great improvement at the main sites of sweating. CONCLUSION: After six weeks, more than 80% of the patients presented with improvements in their overall quality of life and at the most important site of sweating. Side effects were common (80% reported at least one side effect) and caused 25% of the patients to discontinue treatment. Oxybutynin is effective for treating bothersome hyperhidrosis, even at atypical locations and most patients cope well with the side effects. PMID:25318092

Temperament and character properties of primary focal hyperhidrosis patients

PubMed Central

2013-01-01

Background Primary focal hyperhidrosis is a health problem, which has negative effects on the patient's quality of life and significantly affects the patients’ daily activities, social and business life. The aim of this study is to evaluate temperament and character properties of patients diagnosed with primary focal hyperhidrosis. Methods Fifty-six primary focal hyperhidrosis (22.42 ± 7.80) and 49 control subjects (24.48 ± 5.17) participated in the study. Patients who met the diagnostic criteria for PFH were referred to psychiatry clinic where the subjects were evaluated through Structured Clinical Interview for DSM Disorders-I and Temperament and Character Inventory. Results In order to examine the difference between the PFH and control group in terms of temperament and character properties, one-way Multivariate Analysis of Variance (MANOVA) was conducted. In terms of temperament properties, PFH group took significantly higher scores than control group in Fatigability and asthenia dimension. In terms of character properties, PFH group scored significantly lower than control group in Purposefulness , Resourcefulness , Self-Directedness and scored significantly higher than control group in Self-forgetfulness and Self-Transcendence. Conclusion Temperament and character features of PFH patients were different from healthy group and it was considered that these features were affected by many factors including genetic, biological, environmental, socio-cultural elements. During the follow-up of PFH cases, psychiatric evaluation is important and interventions, especially psychotherapeutic interventions can increase the chances of success of the dermatological treatments and can have a positive impact on the quality of life and social cohesion of chronic cases.

To assess the incidence and severity of self-reported hyperhidrosis in patients with amputation and understand its effects on prosthetic fit or function, a cross-sectional survey of patients at two amputee clinics was performed. Responses from 121 subjects with lower-limb amputation were analyzed. Of these subjects, 66% reported sweating to a degree that it interfered with daily activities, as measured by the Hyperhidrosis Disease Severity Scale. There was a significant association between sweating and interference with prosthetic fit and function. Sweating was more severe in cases of transtibial amputations, patients under the age of 60, warm weather, and vigorous activity. There was no relationship between severity of sweating and time since amputation, etiology of amputation, duration of daily prosthetic use, or reported ability to perform functional tasks. Subjects reported trying multiple interventions, but the self-reported effectiveness of these treatments was low. Hyperhidrosis, a common problem associated with prosthetic usage, varies in severity and often interferes with daily activities. Sweating severity is associated with poor prosthetic fit and function. Risk factors include younger age and transtibial amputation status. Treatment strategies generally lack efficacy. The results of this study may provide guidance for future interventions and treatment options.

Oral anticholinergic drugs, such as oxybutynin, are often used in the treatment of hyperhidrosis, but few studies have focused on dosing strategies for children. The objective was to assess the effectiveness and safety of individualized dosing regimens of oral oxybutynin for treating primary focal hyperhidrosis (PFH) in children and teenagers. A prospective study was performed including patients who initiated treatment for hyperhidrosis between November 2011 and November 2014. Response to treatment and adverse effects were evaluated using the Hyperhidrosis Disease Severity Scale at baseline and at 3 and 12 months. Of 16 patients included in the study, 15 (93.8%) had responded to treatment at the 3-month follow-up (62.5% with excellent response). At the 12-month follow-up, the 11 patients who continued the treatment were still responding (63.6% with excellent response). Adverse effects were reported for 68.8% of the patients at 3 months and 54.5% at 12 months, with a predominance of oropharyngeal xerosis. No serious adverse effects were observed. Dose individualization of oral oxybutynin according to clinical response and tolerance observed in each patient is a useful management strategy in children and teenagers. © 2016 Wiley Periodicals, Inc.

Primary focal hyperhidrosis plantaris can cause impairment in social, physical, leisure and occupational activities. Topical treatment with aluminium chloride is the first-line treatment. The aim of this trial was to evaluate efficacy and safety of two different concentrations of aluminium chloride hexa-hydrate (12.5%, 30%) for 6 weeks. 20 volunteers with hyperhidrosis plantaris were included. Efficacy was evaluated using a clinical rating scale of the hyperhidrosis level and qualitative assessments including Minor's (iodine-starch) test and a standardized sniff test. Furthermore a patient questionnaire and measurements of skin surface pH were done to evaluate the subjective assessments and side effects. The hyperhidrosis level significantly decreased in both concentrations. There were no differences in tolerability regarding the skin surface pH and the patient questionnaires. In addition the hidrotic areas decreased after application of both products and the sniff test improved. Topical application of an antiperspirant containing aluminium chloride reduced sweat production in plantar hyperhidrosis significantly. As both 12.5% and 30% were efficacious and safe, we would recommend 12.5% for outpatient treatment. © The Author • Journal compilation © Blackwell Verlag GmbH, Berlin.

A Rare Finding of the Superficial Palmar Arch-Developmental and Clinical Significance

PubMed Central

The ulnar artery provides a major blood supply to the hand in the form of the superficial palmar arch, with the assistance of the radial artery. A rare pattern of the superficial palmar arch was observed in a formalin fixed, male cadaveric left hand. The ulnar artery was only involved in the formation of this arch, which provided three common palmar digital arteries which ran into the second, third and the fourth spaces between the corresponding digits and one proper palmar digital artery which ran along the ulnar side of the little finger. The main trunk of the ulnar artery bifurcated to supply the thumb and the index finger. The superficial branch of the radial artery did not participate in the arch formation. The arch was completed by the radial artery proper on the dorsolateral surface of the hand, after joining the point of bifuracation of the ulnar artery. PMID:23730652

Studies on children with hyperhidrosis are sparse. This retrospective study presents clinical data and quality of life, along with treatment effect and safety of botulinum toxin (BTX). Case reports from 366 children were included to capture the medical history of hyperhidrosis. The total median score of the Dermatology Life Quality Index before treatment was 11 for children aged 16-17 years and 12 for children younger than 16 years. The children described physical, psychosocial and consequence-related symptoms. More than 70% had multifocal hyperhidrosis. BTX-A and/or BTX-B were given to 323 children, 193 of whom received repeated treatments. The highest score in a 5-grade scale concerning treatment effect was reported by 176/193 children, i.e. their "sweating disappeared completely". No severe adverse events occurred. Focal and multifocal hyperhidrosis in children reduces quality of life considerably. Treatment with BTX-A and/or BTX-B has been performed with success.

Lumbar chemical sympathectomy has been performed using fluoroscopic guidance for needle positioning. An 84 year old woman with atherosclerosis obliterans was referred to the pain clinic for intractable cold allodynia of her right foot. A thermogram showed decreased temperature of both feet compared with temperatures above both ankles. The patient agreed to undergo lumbar chemical sympathectomy using fluoroscopy after being informed of the associated risks of nerve injury, hemorrhage, infection, transient back pain, and transient hypotension. During the procedure and three hours afterward, no abnormal signs or symptoms were found except an increase in right leg temperature. The patient was ambulatory after the procedure. However, one day after undergoing lumbar chemical sympathectomy, she visited our emergency department for abdominal discomfort and postural dizziness. Her blood pressure was 80/50 mmHg, and flank tenderness was noted. Retroperitoneal hemorrhage from the second right lumbar segmental artery was shown on computed tomography and angiography. Vital signs were stabilized immediately after embolization into the right lumbar segmental artery. Copyright © 2014 Elsevier Inc. All rights reserved.

We report an acute myelitis in a 53-year-old woman that occurred in 7 days after the diagnosis of Th5-6 herpes zoster. Clinical examination revealed hyperhidrosis of left side of her face, neck, arm and upper chest. She also had muscle weakness of her left leg and sensory impairment for light touch and temperature in her chest and legs. Spinal cord MRI demonstrated a longitudinal T 2 -hyperintense lesion extending from Th1 to 7. In the axial imaging, the lesion dominantly located in the left side gray matter. Hyperhidrosis, weakness and sensory impairment were improved after intravenous therapy with acyclovir and methylprednisolone. VZV (varicella zoster virus) IgG index of the cerebrospinal fluid was high and serological anti aquaporin-4 antibodies were positive at the time of the admission. This case had both characteristics of VZV myelitis and neuromyelitis optica spectrum disorder. Myelitis relapsed 19 months after the first attack. We believe that sympathetic hyper reactivity due to thoracic spinal cord lesion was responsible for the hyperhidrosis in our patient.

Erosion of the palmar (flexor) aspect of the navicular bone is difficult to diagnose with conventional imaging techniques. To review the clinical, magnetic resonance (MR) and pathological features of deep erosions of the palmar aspect of the navicular bone. Cases of deep erosions of the palmar aspect of the navicular bone, diagnosed by standing low field MR imaging, were selected. Clinical details, results of diagnostic procedures, MR features and pathological findings were reviewed. Deep erosions of the palmar aspect of the navicular bone were diagnosed in 16 mature horses, 6 of which were bilaterally lame. Sudden onset of lameness was recorded in 63%. Radiography prior to MR imaging showed equivocal changes in 7 horses. The MR features consisted of focal areas of intermediate or high signal intensity on T1-, T2*- and T2-weighted images and STIR images affecting the dorsal aspect of the deep digital flexor tendon, the fibrocartilage of the palmar aspect, subchondral compact bone and medulla of the navicular bone. On follow-up, 7/16 horses (44%) had been subjected to euthanasia and only one was being worked at its previous level. Erosions of the palmar aspect of the navicular bone were confirmed post mortem in 2 horses. Histologically, the lesions were characterised by localised degeneration of fibrocartilage with underlying focal osteonecrosis and fibroplasia. The adjacent deep digital flexor tendon showed fibril formation and fibrocartilaginous metaplasia. Deep erosions of the palmar aspect of the navicular bone are more easily diagnosed by standing low field MR imaging than by conventional radiography. The lesions involve degeneration of the palmar fibrocartilage with underlying osteonecrosis and fibroplasia affecting the subchondral compact bone and medulla, and carry a poor prognosis for return to performance. Diagnosis of shallow erosive lesions of the palmar fibrocartilage may allow therapeutic intervention earlier in the disease process, thereby preventing

2017-10-02

Limited efficacy, costs, side-effects and complications are issues of concern for most current therapeutic modalities for focal hyperhidrosis. This study evaluated the efficacy of topical oxybutynin 10% gel in treating 61 patients with primary focal hyperhidrosis. The gel was applied to the right or left axilla, palms or soles vs. a placebo compound to the contralateral side for 30 days. A blinded visual grading of the change in starch-iodine tests was performed by 2 non-involved physicians. The Hyperhidrosis Disease Severity Scale (HDSS) and Dermatology Life Quality Index (DLQI) questionnaires were administered before and after treatment. The patients rated their satisfaction with treatment. Fifty-three patients completed the 4-week treatment. Sweat reduction in the drug-treated sweating areas was higher than in the control-treated areas. There was a significant mean improvement in pre- and post-treatment HDSS and DQLI (p = 0.001 for both). Thirty-nine subjects (74%) reported moderate-to-high satisfaction. Twice-daily topical application of oxybutynin 10% gel appears to be an effective, safe and well-tolerated treatment for focal primary hyperhidrosis.

Clonidine is effective for the treatment of primary idiopathic hyperhidrosis and hot flushes: a case report.

PubMed

Albadrani, Ahmed

2017-01-17

While primary hyperhidrosis can be seen in men, accompanying hot flushes is rarely seen in men. Primary hyperhidrosis is thought to be related to overactivity of the sympathetic nervous system while hot flushes are believed to be related to altered peripheral vascular reactivity and a narrowed thermoregulatory zone. I report the case of a 29-year-old man of Arab origin who presented to a dermatology clinic with a complaint of generalized sweating, with heavier involvement of his inguinal region, axilla, and lower back. His complaint was associated with a transient hot sensation and erythema over the affected areas. He did not respond to topical antiperspirants containing aluminum chloride, topical aluminum chloride, or to botulinum toxin A injected in both inguinal areas. He was then referred to an endocrinology clinic to rule out secondary causes of hyperhidrosis and hot flushes; a primary diagnosis was confirmed. He did not respond to oral glycopyrrolate and additionally was complaining of its anticholinergic side effects. The glycopyrrolate was then replaced with oral clonidine 0.15 mg twice a day. Clonidine was well tolerated without remarkable side effects and he quickly started to feel marked improvement which was maintained for 2 years. I report an atypical presentation of primary hyperhidrosis and hot flushes that was effectively controlled by clonidine without remarkable side effects. Further research on a large number of patients may be required before recommending clonidine in similar conditions.

Forty-two patients with axillary hyperhidrosis on the waiting list for surgery were treated with topical saturated solution of aluminium chloride hexahydrate in absolute alcohol. There have been 7 failures. Three patients were unable to cope with the treatment and 4 more experienced severe local irritation or soreness; these 4 were submitted to local surgery. This is a simple and effective treatment for the majority of cases of severe axillary sweating. PMID:548949

LUMBAR SYMPATHECTOMY BY ELECTROCOAGULATION—Its Use in the Management of Certain Vascular and Visceral Disorders

1954-01-01

Although normally the sympathetic nerves aid vascular dilatation during effort, in certain diseases of the vascular system they have a reverse effect. Abolition of sympathetic vasoconstrictive impulses by sympathectomy is the most effective treatment in some chronic peripheral vascular conditions. The authors have used electrocoagulation for a number of years and found it quick, effective and more likely to prevent regeneration of the affected nerves. Improvement was obtained by sympathectomy in arteriosclerotic vascular insufficiency, thromboangiitis obliterans, Raynaud's disease, reflex sympathetic dystrophy following thrombophlebitis or trauma, scleroderma, spinal sympathetic dystrophy and acquired megacolon. A case of causalgia was aggravated by the operation. Abstention from the use of tobacco appears to be sufficient for control of symptoms in many cases. Since vasospasm is manifested in many conditions long before a thrombotic catastrophe occurs, not only relief of symptoms but prevention of irreversible changes may be achieved by early operation.

This case study details the unusual clinical findings in a unique paw-pad disorder that recently emerged among 2 male and 1 female naïve purpose-bred beagle dogs (Canis familiaris) newly received into our facility. During acclimation period physical examinations, the affected dogs demonstrated constantly moist, soft paw pads on all 4 feet. No information was available regarding the epidemiology and pathogenesis of this pad condition in beagle dogs. Here, we report the results of physical examination, clinical chemistry analysis, hematology, histopathology, detailed observations, and novel testing techniques performed during the acclimation period. Histopathology of several sections of affected footpads was compared with that of an age-matched dog with clinically normal paw pads. We describe the morphologic features of a distinctive cutaneous canine footpad condition and discuss the possible differential diagnoses. The histologic and clinical features were most consistent with those of hyperhidrosis; to our knowledge, this report is the first description of hyperhidrosis as a distinct condition in purpose-bred beagle dogs.

Palmprints are identified using matching of minutia points, which can be time consuming for fingerprint experts and in database searches. This article analyzes the operational characteristics of a palmar flexion crease (PFC) identification software tool, using a dataset of 10 replicates of 100 palms, where the user can label and match palmar line features. Results show that 100 palmprint images modified 10 times each using rotation, translation, and additive noise, mimicking some of the characteristics found in crime scene palmar marks, can be identified with a 99.2% genuine acceptance rate and 0% false acceptance rate when labeled within 3.5 mm of the PFC. Partial palmprint images can also be identified using the same method to filter the dataset prior to traditional matching, while maintaining an effective genuine acceptance rate. The work shows that identification using PFCs can improve palmprint identification through integration with existing systems, and through dedicated palmprint identification applications. © 2013 American Academy of Forensic Sciences.

Quantitative palmar dermatoglyphics and the assessment of population affinities: data from marine fishermen of Puri, India.

1988-09-01

Variation in quantitative dermatoglyphics among three endogamous groups of marine fishermen of Puri Coast, India, is greater for the palmar variables than for the fingers. This is the case in both the sexes. The pattern of population affinities, however, differs for the males and females. In order to evaluate the importance of palmar variables in population studies, the results in males are compared with those of finger variables and anthropometrics. There is no significant heterogeneity between the groups for finger variables. Although significant intergroup variability is observed in the palmar and anthropometric traits, the two sets of results are not in the same direction. Palmar dermatoglyphic relationships reflect the caste affiliations, while the anthropometric are in line with geographic proximity.

There is limited evidence regarding the precise location and connections of thermoregulatory centers in humans. We present two patients managed with subthalamic nucleus (STN) Deep Brain Stimulation (DBS) for motor fluctuations in PD that developed reproducible hyperhidrosis with high frequency DBS. To describe the clinical features and analyze the location of the electrodes leading to autonomic activation in both patients. We retrospectively assessed the anatomical localization, electrode programming settings and effects of unilateral STN DBS leading to hyperhidrosis. Unilateral stimulation of anterior and medially located contacts within the STN and zona incerta (Zi) caused bilateral, consistent, reproducible, and reversible sweating in our patients. Adequate control of motor symptoms without autonomic side effects was accomplished with alternative programming settings. Stimulation of the medial Zi and medial and anterior STN causes hyperhidrosis in a pattern similar to that described in primates and rats. We speculate that central autonomic fibers originating in the lateral hypothalamic area project laterally to the ventral/medial Zi and then to brainstem nuclei following an medial and posterior trajectory in relationship to STN.

To evaluate the efficacy and safety of onabotulinumtoxinA in adolescents with primary axillary hyperhidrosis. This 52-week, multicenter, nonrandomized, open-label study was conducted in 141 adolescents ages 12 to 17 years with severe primary axillary hyperhidrosis. Patients could receive up to six treatments with onabotulinumtoxinA (50 U per axilla), with re-treatment occurring no sooner than 8 weeks after the prior treatment cycle and no later than 44 weeks after the initial treatment cycle. The primary efficacy measure was treatment response, based on self-assessed hyperhidrosis severity following the first two treatments using the 4-point Hyperhidrosis Disease Severity Scale (HDSS). Other efficacy measures included spontaneous resting sweat production and health outcomes. Fifty-six (38.9%) participants underwent one treatment, 59 (41.0%) underwent two, 20 (13.9%) underwent three, 6 (4.2%) underwent four, and 3 (2.1%) underwent five. OnabotulinumtoxinA significantly improved HDSS scores and decreased sweat production compared with treatment cycle baselines. Seventy-nine patients (54.9%) responded to treatment based on HDSS criteria. From 56.6% to 72.3% of patients experienced a two-grade or more improvement at 4 and 8 weeks after each of the first two treatments. The majority (79.4%-93.2%) had a 75% or greater reduction in sweat production at week 4 (treatments 1-3). The median duration of effect for responders ranged from 134 to 152 days. Using quality of life measures, health outcomes improved markedly. Eight patients (5.6%) had mild or moderate treatment-related adverse events. No unexpected safety signals were observed in this study. Neutralizing antibodies to onabotulinumtoxinA did not develop. OnabotulinumtoxinA injections provided beneficial effects in adolescents with primary axillary hyperhidrosis. © 2015 The Authors. Pediatric Dermatology Published by Wiley Periodicals, Inc.

Primary focal axillary hyperhidrosis is a disorder of excessive sweating that can strongly impact quality of life. The objective if this study was to compare microwave ablation (MA), botulinum toxin (BT) injection, and liposuction-curettage (LC) in the treatment of primary axillary hyperhidrosis based on subjective and objective criteria. A systematic review of the literature published in French or English between 1 January 1991 and 1 February 2015 was completed using PubMed and Embase databases. 16 of 775 articles were selected based on relevance and criteria of inclusion and exclusion. The three methods proved to be efficient and safe; however, MA and BT had better results when compared to LC in the short term. Both MA and LC showed longer lasting results when compared to BT. However, in the long term, MA was superior to LC. MA, LC, and BT injections are safe and efficient minimally invasive alternatives for the treatment of axillary hyperhidrosis. Well-designed randomized controlled trials are needed to further compare the efficacy of these techniques.

Palmar dermatoglyphic patterns in twins.

Jacques, S M; Salzano, F M; Penña, H F

1977-01-01

The role of genetic factors in the determination of palmar dermatoglyphic patterns was investigated in a series of 49 MZ and 51 DZ twins, using Spearman's rank correlation and analysis of variance. Both methods indicated that the genetic effect in the distribution of patterns is highest in the interdigital III and lowest in the interdigital IV regions, the hypothenar and thenar showing intermediate values. As for interdigital II, no evaluation of genetic effects was possible using the nonparametric test, but the estimates of genetic variance indicate that inherited factors may play a relatively minor role in the pattern distribution of this area.

Analysis of the quantitative dermatoglyphics of the digito-palmar complex in patients with multiple sclerosis.

Supe, S; Milicić, J; Pavićević, R

1997-06-01

Recent studies on the etiopathogenesis of multiple sclerosis (MS) all point out that there is a polygenetical predisposition for this illness. The so called "MS Trait" determines the reactivity of the immunological system upon ecological factors. The development of the glyphological science and the study of the characteristics of the digito-palmar dermatoglyphic complex (for which it was established that they are polygenetically determined characteristics) all enable a better insight into the genetic development during early embriogenesis. The aim of this study was to estimate certain differences in the dermatoglyphics of digito-palmar complexes between the group with multiple sclerosis and the comparable, phenotypically healthy groups of both sexes. This study is based on the analysis of 18 quantitative characteristics of the digito-palmar complex in 125 patients with multiple sclerosis (41 males and 84 females) in comparison to a group of 400 phenotypically healthy patients (200 males and 200 females). The conducted analysis pointed towards a statistically significant decrease of the number of digital and palmar ridges, as well as with lower values of atd angles in a group of MS patients of both sexes. The main discriminators were the characteristic palmar dermatoglyphics with the possibility that the discriminate analysis classifies over 80% of the examinees which exceeds the statistical significance. The results of this study suggest a possible discrimination of patients with MS and the phenotypically health population through the analysis of the dermatoglyphic status, and therefore the possibility that multiple sclerosis is genetically predisposed disease.

Mattison, Siobhán M; Brunson, Emily K; Holman, Darryl J

2015-09-01

A normal human palm contains 3 major creases: the distal transverse crease; the proximal transverse crease; and the thenar crease. Because permanent crease patterns are thought to be laid down during the first trimester, researchers have speculated that deviations in crease patterns could be indicative of insults during fetal development. The purpose of this study was twofold: (1) to compare the efficacy and reliability of two coding methods, the first (M1) classifying both "simiana" and Sydney line variants and the second (M2) counting the total number of crease points of origin on the radial border of the hand; and (2) to ascertain the relationship between palmar crease patterns and fetal alcohol spectrum disorders (FASD). Bilateral palm prints were taken using the carbon paper and tape method from 237 individuals diagnosed with FASD and 190 unexposed controls. All prints were coded for crease variants under M1 and M2. Additionally, a random sample of 98 matched (right and left) prints was selected from the controls to determine the reliabilities of M1 and M2. For this analysis, each palm was read twice, at different times, by two readers. Intra-observer Kappa coefficients were similar under both methods, ranging from 0.804-0.910. Inter-observer Kappa coefficients ranged from 0.582-0.623 under M1 and from 0.647-0.757 under M2. Using data from the entire sample of 427 prints and controlling for sex and ethnicity (white v. non-white), no relationship was found between palmar crease variants and FASD. Our results suggest that palmar creases can be classified reliably, but palmar crease patterns may not be affected by fetal alcohol exposure.

To determine functional and morphologic changes in palmar digital nerves after nonfocused extracorporeal shock wave (ESW) treatment in horses. 6 horses. The medial and lateral palmar digital nerves of the left forelimb were treated with nonfocused ESWs. The medial palmar digital nerve of the right forelimb served as a nontreated control nerve. At 3, 7, and 35 days after treatment, respectively, 2 horses each were anesthetized and nerves were surgically exposed. Sensory nerve conduction velocities (SNCVs) of treated and control nerves were recorded, after which palmar digital neurectomies were performed. Morphologic changes in nerves were assessed via transmission electron microscopy. Significantly lower SNCV in treated medial and lateral nerves, compared with control nerves, was found 3 and 7 days after treatment. A significantly lower SNCV was detected in treated medial but not lateral nerves 35 days after treatment. Transmission electron microscopy of treated nerves revealed disruption of the myelin sheath with no evidence of damage to Schwann cell bodies or axons, 3, 7, and 35 days after treatment. Nonfocused ESW treatment of the metacarpophalangeal area resulted in lower SNCV in palmar digital nerves. This effect likely contributes to the post-treatment analgesia observed in horses and may result in altered peripheral pain perception. Horses with preexisting lesions may be at greater risk of sustaining catastrophic injuries when exercised after treatment.

Dependence of palmar sweating response and central nervous system activity on the frequency of whole-body vibration.

PubMed

Ando, Hideo; Noguchi, Ryo

2003-06-01

This study was carried out to determine the effects of the frequency of whole-body vibration on palmar sweating response and the activity of the central sympathetic nervous system. Palmar sweating volume was measured on the right palm of six healthy men before and during 3 minutes of exposure to sinusoidal whole-body vibration at three different frequencies (16, 31.5, and 63 Hz). The whole-body vibration had a frequency-weighted, root mean square (rms) acceleration magnitude of 2.0 m/s2. As the index of the activated central sympathetic nervous system, saliva level of 3-methoxy-4-hydroxyphenylglycol (MHPG) was analyzed before and immediately after each vibration exposure. Each vibration frequency induced a palmar sweating response, that of 31.5 Hz being the largest. However, no significant difference was found between the three vibration conditions. Saliva MHPG increased in all the vibration exposures, and the largest change was observed at 31.5 Hz, the difference being significant. Acute exposure to whole-body vibration induced a palmar sweating response and activated the central sympathetic nervous system. The effects on the central nervous system were found to be dependent on the frequency of the vibration.

Influences of chemical sympathectomy and simulated weightlessness on male and female rats

Consideration is given to a study aimed at determining whether the sympathetic nervous system is associated with the changes in maximum oxygen consumption (VO2max), run time, and mechanical efficiency observed during simulated weightlessness in male and female rats. Female and male rats were compared for food consumption, body mass, and body composition in conditions of simulated weightlessness to provide an insight into how these parameters may influence aerobic capacity and exercise performance. It is concluded that chemical sympathectomy and/or a weight-bearing stimulus will attenuate the loss in VO2max associated with simulated weightlessness in rats despite similar changes in body mass and composition. It is noted that the mechanisms remain unclear at this time.

Periostin differentially induces proliferation, contraction and apoptosis of primary Dupuytren's disease and adjacent palmar fascia cells

Dupuytren's disease, (DD), is a fibroproliferative condition of the palmar fascia in the hand, typically resulting in permanent contracture of one or more fingers. This fibromatosis is similar to scarring and other fibroses in displaying excess collagen secretion and contractile myofibroblast differentiation. In this report we expand on previous data demonstrating that POSTN mRNA, which encodes the extra-cellular matrix protein periostin, is up-regulated in Dupuytren's disease cord tissue relative to phenotypically normal palmar fascia. We demonstrate that the protein product of POSTN, periostin, is abundant in Dupuytren's disease cord tissue while little or no periostin immunoreactivity is evident in patient-matchedmore » control tissues. The relevance of periostin up-regulation in DD was assessed in primary cultures of cells derived from diseased and phenotypically unaffected palmar fascia from the same patients. These cells were grown in type-1 collagen-enriched culture conditions with or without periostin addition to more closely replicate the in vivo environment. Periostin was found to differentially regulate the apoptosis, proliferation, {alpha} smooth muscle actin expression and stressed Fibroblast Populated Collagen Lattice contraction of these cell types. We hypothesize that periostin, secreted by disease cord myofibroblasts into the extra-cellular matrix, promotes the transition of resident fibroblasts in the palmar fascia toward a myofibroblast phenotype, thereby promoting disease progression.« less

A new percutaneous approach to sympathectomy using radiofrequency denervation has seemed to offer longer duration and less incidence of postsympathetic neuralgia as compared to phenol sympathetic blocks. To compare these techniques, 17 patients underwent either phenol lumbar sympathetic blocks (n = 9) or radiofrequency denervation (n = 8). Duration of sympathetic block was followed by a sweat test and temperature measurements. Results indicate that 89% of patients in the phenol group showed signs of sympathetic blockade after 8 weeks, as compared to 12% in the radiofrequency group (P less than 0.05). Although the incidence of post sympathetic neuralgia appears tomore » be less with radiofrequency denervation, further refinement of needle placement to ensure complete lesioning of the sympathetic chain will be required before the technique can offer advantages over current phenol techniques.« less

Elevated concentrations of doxorubicin are found in eccrine sweat glands of the palms and soles. We therefore evaluated an antiperspirant as preventive treatment for palmar-plantar erythrodysesthesia (hand-foot syndrome) in patients with metastatic breast cancer treated with pegylated liposomal doxorubicin. An antiperspirant containing aluminum chlorohydrate or placebo cream was applied to the left or right hand and foot in a double-blinded manner (intra-patient randomization). The primary endpoint was the rate of grade 2 or 3 palmar-plantar erythrodysesthesia. A secondary endpoint was the patient-reported symptom burden (tingling, numbness, pain, or skin problems). Using McNemar's matched pairs design, 53 patients were needed to detect a 20% difference between the treatment and placebo sides with a significance level of 5% and power of 90%. Grade 2 or 3 PPE occurred in 30 (58%) of 52 evaluable patients; in six patients adverse effects occurred on the placebo side but not on the treatment side, whereas one patient developed palmar-plantar erythrodysesthesia on the treatment side only (P = 0.07). Four patients developed grade 2 or 3 palmar-plantar erythrodysesthesia on their foot on the placebo side but not on the treatment side (P = 0.05). In the cohort with grade 2 or 3 palmar-plantar erythrodysesthesia there was a trend towards fewer dermatologic symptomatologies with the active treatment (P = 0.05), and no difference for other adverse events. Using topical aluminum chlorohydrate as an antiperspirant appears to reduce the incidence of grade 2 or 3 palmar-plantar erythrodysesthesia following pegylated liposomal doxorubicin chemotherapy for metastatic breast cancer.

Objectives To evaluate the safety and efficacy of botulinum toxin type A in the treatment of bilateral primary axillary hyperhidrosis. Design Multicentre, randomised, parallel group, placebo controlled trial. Setting 17 dermatology and neurology clinics in Belgium, Germany, Switzerland, and the United Kingdom. Participants Patients aged 18-75 years with bilateral primary axillary hyperhidrosis sufficient to interfere with daily living. 465 were screened, 320 randomised, and 307 completed the study. Interventions Patients received either botulinum toxin type A (Botox) 50 U per axilla or placebo by 10-15 intradermal injections evenly distributed within the hyperhidrotic area of each axilla, defined by Minor's iodine starch test. Main outcome measures Percentage of responders (patients with ⩾50% reduction from baseline of spontaneous axillary sweat production) at four weeks, patients' global assessment of treatment satisfaction score, and adverse events. Results At four weeks, 94% (227) of the botulinum toxin type A group had responded compared with 36% (28) of the placebo group. By week 16, response rates were 82% (198) and 21% (16), respectively. The results for all other measures of efficacy were significantly better in the botulinum toxin group than the placebo group. Significantly higher patient satisfaction was reported in the botulinum toxin type A group than the placebo group (3.3 v 0.8, P<0.001 at 4 weeks). Adverse events were reported by only 27 patients (11%) in the botulinum toxin group and four (5%) in the placebo group (P>0.05). Conclusion Botulinum toxin type A is a safe and effective treatment for primary axillary hyperhidrosis and produces high levels of patient satisfaction. What is already known on this topicPrimary hyperhidrosis is a chronic disorder that can affect any part of the body, especially the axillas, palms, feet, and faceCurrent treatments are often ineffective, short acting, or poorly toleratedWhat this study addsBotulinum toxin type

Palm prints formed once does not change throughout life and is not influenced by environment. Palmar Dermatoglyphics can indicate the development of potentially malignant and malignant lesions and help in identifying persons at high risk of developing Oral submucous fibrosis (OSMF) and Oral squamous cell carcinoma (OSSC). To analyze the qualitative [finger ridge pattern and presence or absence of hypothenar pattern] and quantitative [mean ATD angle and total AB ridge count] variations in Palmar Dermatoglyphics in patients suffering from OSMF and OSCC. A prospective comparative study among 40 patients (Group I--10 samples of smokeless tobacco users with OSMF, Group II--10 samples of smokeless tobacco users with OSCC, Group III--10 samples of smokeless tobacco users without OSMF or OSCC and Group IV--10 samples without smokeless tobacco habit without OSMF and OSCC as controls) were selected. The palm prints were recorded using an HP inkjet scanner. The patients were asked to place the palm gently on the scanner with the fingers wide apart from each other. The images of the palm prints were edited and qualitative and quantitative analysis were done. Statistical analysis such as Kruskal Wallis, Post Hoc and Analysis of Varience were done. A highly significant difference among the finger ridge, hypothenar pattern and mean ATD angle (P<0.001) and total AB ridge count (P=0.005) in OSMF and OSCC patients were obtained. There is predominance of arches and loops, presence of hypothenar pattern, decrease in mean ATD angle and total AB ridge count in OSMF and Oral Cancer patients. Palmar Dermatoglyphics can predict the probable occurrence of OSMF and OSCC in smokelees tobacco users.

We developed a new triangular fibrocartilage complex reconstruction technique for distal radioulnar joint instability in which the palmar portion of the triangular fibrocartilage complex was predominantly reconstructed, and evaluated whether such reconstruction can restore stability of the distal radioulnar joint in seven fresh cadaver upper extremities. Distal radioulnar joint instability was induced by cutting all soft-tissue stabilizers around the distal ulna. Using a palmar approach, a palmaris longus tendon graft was sutured to the remnant of the palmar radioulnar and ulnocarpal ligaments. The graft was then passed through a bone tunnel created at the fovea and was sutured. Loads were applied to the radius, and dorsopalmar displacements of the radius relative to the ulna were measured using an electromagnetic tracking device in neutral rotation, 60° supination and 60° pronation. We compared the dorsopalmar displacements before sectioning, before reconstruction and after reconstruction. Dorsopalmar instability produced by sectioning significantly improved in all forearm positions after reconstruction.

Spontaneous periodic episodes of hypothermia still defy medical knowledge. In 1969, Shapiro et al. described the first two cases of spontaneous periodic hypothermia associated with agenesis of the corpus callosum. Recently, Dundar et al. reported a case of spontaneous periodic hypothermia and hyperhidrosis without corpus callosum agenesis, suggesting that the periodic episodes of hypothermia might be of epileptiform origin. Here we describe two paediatric patients with spontaneous periodic hypothermia without corpus callosum agenesis and demonstrate, to our knowledge for the first time, altered levels of neurotransmitter metabolites within the cerebrospinal fluid. © The Authors.

Simultaneous Median and Ulnar Compression Neuropathy Secondary to a Giant Palmar Lipoma: A Case Report and Review of the Literature

PubMed Central

Unal, Melih; Demirayak, Engin; Acar, Baver

2018-01-01

Lipomas are benign tumors that rarely settle in the hand. They usually present with mass, pain, and nerve compression symptoms. Although isolated median or ulnar nerve compression neuropathy secondary to a lipoma of the hand has been widely reported, simultaneous median and ulnar nerve compression neuropathy are exceedingly rare and there are only three reported cases in the current literature to date. Herein, a case of a 50-year-old woman with a giant palmar lipoma that caused median and ulnar compression neuropathy is presented. The removal of the tumor resulted in the complete recovery of the patient’s symptoms. A deep-seated palmar lipoma should be kept in mind in patients with unilateral compression neuropathy symptoms with a palmar mass. PMID:29666776

Comminuted Distal Radial Fracture with Large Rotated Palmar Medial Osteochondral Fragment in the Joint.

2018-01-01

Intra-articular distal radius fractures have long been massively discussed in the literature, but regarding to fractures that possess rotated volar medial fragment in the joint a few amount papers has been written. In this article, we would like to emphasize the significance of the rotated palmar medial (lunate facet) fragment. A 39-year-old man fell from a height of about 3 m and landed on his right outstretched hand; within 40 min, he arrived at our clinic presenting with a severe pain and swelling in his right wrist. Initial X-rays of the wrist revealed dorsal subluxation of the radiocarpal joint with dorsal comminution of the radial articular surface and fracture of the radial styloid process, with (nearly inverted) ~ 140-150° rotation of the palmar medial fragment. With an additional volar approach, the fragment reduced and stabilized with two K-wires and wrist immobilized in external fixator. The patient returned to daily activities without any discomfort and pain after the 1 year from the surgery. Overlooking of palmar rotated osteochondral fragment will cause deficiency to build proper pre-operative strategy to approach the reduction of the fragment. The incompetence of reduction will deteriorate the articular surface and lead to early osteoarthritis of the wrist. The surgeon should detect this fragment and should be familiar with volar approaches of the wrist. Above average surgical experience would be needed for successful reduction.

Cooling modifies mixed median and ulnar palmar studies in carpal tunnel syndrome.

Araújo, Rogério Gayer Machado de; Kouyoumdjian, João Aris

2007-09-01

Temperature is an important and common variable that modifies nerve conduction study parameters in practice. Here we compare the effect of cooling on the mixed palmar median to ulnar negative peak-latency difference (PMU) in electrodiagnosis of carpal tunnel syndrome (CTS). Controls were 22 subjects (19 women, mean age 42.1 years, 44 hands). Patients were diagnosed with mild symptomatic CTS (25 women, mean age 46.6 years, 34 hands). PMU was obtained at the usual temperature, >32 degrees C, and after wrist/hand cooling to <27 degrees C in ice water. After cooling, there was a significantly greater increase in PMU and mixed ulnar palmar latency in patients versus controls. We concluded that cooling significantly modifies the PMU. We propose that the latencies of compressed nerve overreact to cooling and that this response could be a useful tool for incipient CTS electrodiagnosis. There was a significant latency overreaction of the ulnar nerve to cooling in CTS patients. We hypothesize that subclinical ulnar nerve compression is associated with CTS.

1989-01-01

The effects of simulated weightlessness (hind-limb suspension) and chemical sympathectomy (by repeated injections with guanethidine sulfate) on the maximum oxygen consumption (VO2 max) of female rats were investigated in rats assigned for 14 days to one of three groups: a head-down hind-limb suspension, a horizontal suspension with hind limbs weight bearing, or the caged control. The VO2 max values were assessed by having rats run on a treadmill enclosed in an airtight chamber. The hind-limb-suspended sympathectomized rats were found to exhibit shorter run times and lower mechanical efficiencies, compared to their presuspension values or the values from saline-injected suspended controls. On the other hand, the suspended sympathectomized rats did not demonstrate a decrease in the VO2 max values that was observed in saline-injected controls.

Circumscribed palmar hypokeratosis (CPH) is a rare skin disease, first described in 2002, associated with sudden localized reduction of the corneal layer. In most cases, it presents as an isolated rounded erythematous palmar lesion on the thenar eminence. We describe the dermoscopic semiology of CPH in 3 cases. Three patients between the ages of 59 and 72 presented very limited erythematous lesions suggestive of CPH. Dermoscopic examination of these lesions provided similar findings. Biopsy, which was performed in one patient, confirmed the diagnosis of CPH. Two dermoscopic elements of CPH are characteristic: (1) the sides of the lesion have a "stair step" or "geological strata" type of configuration, and the thickness of the different strata varies; (2) the centre of the lesion showed a homogeneous erythematous area with a vascular pattern composed of dotted vessels of the superficial dermis and sometime vascular loops. These dermoscopic aspects are characteristic and enable CPH to be differentiated from Bowen's disease or porokeratosis of Mibelli. In Bowen's disease, there is no stair step like aspect to the sides of lesions; further, the centre of the lesion shows glomerular vessels (coiled vessels) and/or globular vessels (small red clods). In porokeratosis, peripheral keratotic "white track" structures comprise a single pigmented channel or a double white line. There is no "stair step" or central vascular pattern. The dermoscopic semiology of CPH is highly characteristic and enables differentiation from Bowen's disease and porokeratosis. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

To investigate the use of rimabotulinumtoxinB (BoNT/B [Myobloc]) compared with placebo in treating hyperhidrosis in the residual limbs of individuals with amputation. Randomized, double-blind, placebo-controlled pilot study. Military medical center. Male participants (N=9) with 11 major amputations of the lower limbs and who complained of excessive sweating in their residual limbs were enrolled in the study between September 24, 2008 to October 28, 2011. Participants' lower limbs were randomly assigned to receive injections of either BoNT/B (n=7) or placebo (n=4). BoNT/B. The primary efficacy variable was a minimum of 50% reduction in sweat production 4 weeks after the injection as measured via gravimetric sweat analysis after 10 minutes of physical exertion. Secondary analyses were performed on prosthetic function and pain. All volunteers (100%; 7) in the BoNT/B group achieved a minimum of 50% reduction in sweat production as compared with only 50% (2) in the placebo group. The percent reduction was significantly greater for the BoNT/B group than for the placebo group (-72.7%±15.7% vs -32.7%±39.2%; P<.05). Although both groups subjectively self-reported significant sweat reduction and improved prosthetic function (P<.05 for both), objective gravimetric sweat analyses significantly decreased only for the BoNT/B group (2.3±2.3g vs 0.7±1.1g; P<.05). Neither group reported a change in phantom limb pain or residual limb pain (P>.05 for both). BoNT/B successfully reduces sweat production in individuals with residual limb hyperhidrosis, but does not affect pain. No differences were found in perceived effect on prosthetic use between BoNT/B and placebo groups. Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

There is no consensus regarding etiology or best surgical technique for severe Raynaud syndrome in patients with connective tissue disease. Observations after 30 years' experience in more than 100 cases led to the conclusion that an extended periarterial sympathectomy (with or without vein-graft reconstruction) and adjunctive use of Botox topically will offer benefits that exceed palliation and reduce recurrent ulcerations. In this article the rationale for this approach is reviewed, techniques and results are outlined, and a hypothesis for the mechanism of Raynaud attacks is offered. Copyright © 2015 Elsevier Inc.

Primary axillary hyperhidrosis (PAH) creates social stress in patients. Although there are several options for treating PAH, only surgical modalities have conferred a permanent solution. This study evaluated the clinical effectiveness of fractionated microneedle radiofrequency (FMR) treatment for PAH. This study is based on a single-blind, sham control comparative design. In all, 25 patients with severe PAH underwent three sessions of FMR at 3-week intervals. One side was treated with FMR while the other was sham controlled. Efficacy was evaluated using the hyperhidrosis disease severity scale (HDSS), sweating intensity visual analogue scale (VAS) and patient satisfaction at baseline, 3 weeks after each session and at 3 months after the last. Skin biopsies were obtained from two enrolled patients. The HDSS and VAS demonstrated significant improvement after treatment on the treated side in comparison with the control side. The mean ± SD of the HDSS after 21 weeks were 1.87 ± 0.61 and 3.38 ± 0.49 (P < 0.001) for the treated and the controlled side, respectively. The follow-up evaluation revealed that 79% of the patients showed a 1 or 2-score decrease in HDSS. In total, 80% of patients reported more than 50% satisfaction at the end of the study. Histopathological findings showed a decrease of the number of the sweat glands in the treated side, confirming the above findings. Treatment of PAH with FMR as a non-invasive modality can be a safe option with positive therapeutic effects on HDSS without any long-lasting side effects. © 2014 The Australasian College of Dermatologists.

2008-01-01

The cornea is one of the most highly innervated tissues in the mammalian host. We hypothesized changes to cornea innervation through chemical sympathectomy would significantly alter the host response to the neurotropic viral pathogen, herpes simplex virus type 1 (HSV-1) following ocular infection. Mice treated with 6-hydroxydopamine hydrobromide displayed reduced tyrosine hydroxylase-positive fibers residing in the cornea. Sympathectomized mice were also found to show a transient rise in virus recovered in infected tissues and succumbed to infection in greater numbers. Whereas there were no differences in infiltrating leukocyte populations including HSV-1-specific cytotoxic T lymphocytes in the infected tissue, an increase in substance P and a decrease in IFN-γ levels in the trigeminal ganglion but not brain stem of sympathectomized mice were noted. Sympathectomized mice treated with the neurokinin-1 receptor antagonist L703,606 had delayed mortality implicating the involvement of substance P in HSV-1-mediated death. PMID:18495255

Fingertip reconstruction with a palmar advancement flap and free dermal graft: a report of six cases.

PubMed

Arons, M S

1985-03-01

The palmar thumb advancement flap was first described by Moberg in 1964. It was further utilized for the thumb and defined by Posner and Smith in 1971. In 1980, Macht and Watson favorably reported their technique of palmar advancement that was applicable not only for the thumb, but also for all five digits with soft tissue tip losses. A further refinement of their technique is to augment the digital tip with an autogenous dermal graft. This dermal "padding" is placed directly over the bony tuft to act as a "shock absorber," add bulk and contour to the distal tip of the finger, increase soft tissue stability, eliminate direct percussive tenderness of the bone, and decrease disability for specific occupations such as those requiring typewriting. Six cases are reported.

To examine the potential for treatment of palmar adhesions associated with Dupuytren's contracture using instrument-assisted cross-frictional massage (CFM) and stretching. This was a prospective case study. The primary intervention consisted of a 2-min multi-planar CFM over the affected area of the palm, followed by a 2-min maximal finger-extension stretch. Following eight weeks of treatment there were increases in both passive and active extension range of motion of the digits, reduction in the visibility of palmar adhesions, and subjective improvements in hand function. This treatment protocol may offer a substitute for the current invasive surgical and injection procedures that are available. Copyright © 2011 Elsevier Ltd. All rights reserved.

Background: Primary focal axillary hyperhidrosis is a chronic distressing disorder affecting both the sexes. When the condition is refractory to conservative management, we should go for more promising therapies like intradermal botulinum toxin A (BtxA) injections in the axilla, and surgical therapies like subcutaneous curettage of sweat glands. Aims and Objectives: The aim of this study is to compare the efficacy, safety and duration of action of intradermal BtxA injections in one axilla and subcutaneous curettage of sweat glands in the other axilla of the same patient with axillary hyperhidrosis. Materials and Methods: Twenty patients (40 axillae) received intradermal BtxA injections on the right side (20 axillae) and underwent tumescent subcutaneous curettage of sweat glands on the left side (20 axillae). Sweat production rate was measured using gravimetry analyses at baseline and at 3 months after the procedure. Subjective analyses were done using hyperhidrosis disease severity scale (HDSS) score at baseline, at 3rd and 6th month after the procedure. Results: At 3 months post-treatment, the resting sweat rate in the toxin group improved by 80.32% versus 79.79% in the subcutaneous curettage method (P = 0.21). Exercise-induced sweat rate in the toxin group improved by 88.76% versus 88.8% in the subcutaneous curettage group (P = 0.9). There was a significant difference in the HDSS score after treatment with both the modalities. There were no adverse events with BtxA treatment compared to very minor adverse events with the surgical method. Conclusion: Both intradermal BtxA injections and tumescent subcutaneous curettage of sweat glands had a significant decrease in the sweat rates with no significant difference between the two modalities. Hence, in resource poor settings where affordability of BtxA injection is a constraint, subcutaneous curettage of sweat glands can be preferred which has been found equally effective with no or minimal adverse events.

1983-01-01

Delivery of ketoconazole to human stratum corneum was studied. Thirteen healthy volunteers, three patients with chronic fungal disease and one patient with palmar-plantar hyperhidrosis were given 400 mg of ketoconazole daily for various lengths of time. The ketoconazole content of palmar stratum corneum, eccrine sweat, sebum, and serum was measured by high-pressure liquid chromatography (sensitivity, 0.005 to 0.010 microgram/ml). Palmar stratum corneum obtained after 7 and 14 days of daily administration contained up to 14 micrograms of ketoconazole per g. Ketoconazole was not found in sebum after 7 or 14 days of daily ingestion of the antimycotic agent. Sebum from three patients with chronic fungal infection treated for greater than 9 months contained ketoconazole (means, 4.7 micrograms/g). Thermogenic whole body eccrine sweat contained a mean of 0.059 microgram/ml on day 7 and 0.084 microgram/ml on day 14 of daily administration. Ketoconazole appeared in thermogenic whole body eccrine sweat and palmar hyperhidrotic sweat within 1 h after a single oral dose. Partition studies of ketoconazole containing eccrine sweat demonstrated a 10-fold greater concentration in the sediment phase (desquamated keratinocytes) compared with the clear supernatant phase. In vitro studies with [3H]ketoconazole-supplemented supernatant sweat revealed preferential binding to stratum corneum, hair, and nails and its partitioning to lipid-rich sebum. We conclude that eccrine sweat rapidly transports ketoconazole across the blood-skin barrier, where it may bind or partition to keratinocytes and surface lipids. PMID:6318663

Despite its effectiveness in treating primary axillary hyperhidrosis (PAH), topical botulinum toxin type A (BTX-A) is highly resistant to transdermal absorption. Topical BTX-A liposomal cream is recommended as a novel, noninvasive modality to enhance skin penetration. To evaluate the efficacy and safety of topical BTX-A liposomal cream in comparison with liposomal vehicle cream alone in the treatment of PAH. A prospective, randomized, double-blinded, split-site study was conducted in 20 subjects, aged 18 to 50 years, all of whom had symmetrical axillary sweating with Hyperhidrosis Disease Severity Scale scores between 2 to 4. All subjects were double-blinded to treatment regimens and randomly given 2 bottles, one containing topical BTX-A liposomal cream and one containing the vehicle cream without BTX-A, to be applied consistently to the same axilla nightly for 7 consecutive days. Clinical improvement and adverse reactions were evaluated at every follow-up visit. Axillary skin treated with topical BTX-A demonstrated superior sweat reduction and patient satisfaction to vehicle cream-treated axillary skin, with clinical and statistical significance, at baseline, weeks 2, 4, 6, and 8 of follow-up, without adverse effects. Topical BTX-A liposomal cream pharmaceutically enhances drug delivery, is painless, cost-effective, and overall an innovative treatment of PAH.

Pacing-induced palmar sweating evaluated by unique hygrometer: possible implications of sympathetic activation during tachycardia.

PubMed

Maruyama, T; Yanaga, T; Makino, N

2000-03-01

Although reflex sympathetic activation is a major determinant of the haemodynamic tolerability of ventricular tachycardia (VT), the methods for evaluating this aspect during on-going VT remain invasive and complicated. Palmar sweating as an indirect but non-invasive measure of sympathetic activity was estimated by means of a unique hygrometer under right ventricular (RV) rapid pacing (up to 150 beats min-1) replicating VT, and concurrent monitoring of aortic blood pressure in five patients with various kinds of cardiac arrhythmias in our electrophysiological laboratory. The peak palmar sweating rate in arbitrary units was augmented as the RV pacing rate increased and was proportional to the pacing-induced fall in systolic blood pressure (SBP), with a correlation coefficient of more than 0.903 (P<0.006). The slope of linearity between the sweating rate and the fall in SBP varied among individual patients, with greater sweating amplitude in the younger patients even with the same extent of fall in SBP. This preliminary study suggests sympathetic acceleration caused by haemodynamic deterioration under simulated VT, and therefore this protocol may be able to predict the haemodynamic tolerability of sustained monomorphic VT.

Acropustulosis, or chronic palmar plantar pustulosis (PPP), is a phenomenon of recurrent sterile pustules, erythema, and scaling affecting the palms and soles. Its pathogenesis is unclear, and it is difficult to treat. The purpose of this study was to elucidate further the factors involved in causing PPP, thereby enhancing the ability to manage this disease. All cases of PPP seen at Mayo Clinic Scottsdale from 1987 to 1993 were reviewed. 21 patients with PPP were identified, 15 of whom had been patch tested. 9 of the 15 patients (60%) showed positive patch test results. Fragrance was the most common sensitivity, but nickel, formaldehyde, para-phenylenediamine, thiuram, neomycin, mercury, balsam of Peru, and cinnamic aldehyde sensitivities were demonstrated. Less important factors included atopy, fungal and bacterial infections, and irritation. Although the mechanism of this sterile pustulosis response does not depend solely on delayed hypersensitivity mechanisms, we believe that we have demonstrated such a large number of positive patch tests in this chronic pustular dermatosis that patch testing should be considered in the routine work-up of these patients.

Due to advances in the development of the unidirectional locking plates there is now an increased use of multidirectional palmar locking plates in the treatment of distal radius factures. The purpose of this study was to evaluate a possible improvement of the treatment and results. This prospective cohort study investigated 40 patients with C1 and C2 Colles' fractures who had been treated with unidirectional and multidirectional locking plates. The average time for the follow-up examinations was 12.3 months (range 12-15 months) after surgery. The intra-operative functional (neutral-zero method), radiological and subjective (DASH score, VAS) results were evaluated. The intra-operative fluoroscopy time of the unidirectional group was 58 s shorter compared to the multidirectional group. All fractures healed without any complication. The radiological, subjective (DASH score) and objective results for both groups were good and showed no differences. Unidirectional palmar locking plates are equally suited for the therapy of C1 and C2 fractures as multidirectional palmar locking plates but multidirectional plates require a longer fluoroscopy time.

Some forms of chronic pain are maintained or enhanced by activity in the sympathetic nervous system (SNS), but attempts to model this have yielded conflicting findings. The SNS has both pro- and anti-inflammatory effects on immunity, confounding the interpretation of experiments using global sympathectomy methods. We performed a “microsympathectomy” by cutting the ipsilateral gray rami where they entered the spinal nerves near the L4 and L5 DRG. This led to profound sustained reductions in pain behaviors induced by local DRG inflammation (a rat model of low back pain) and by a peripheral paw inflammation model. Effects of microsympathectomy were evident within one day, making it unlikely that blocking sympathetic sprouting in the local DRGs or hindpaw was the sole mechanism. Prior microsympathectomy greatly reduced hyperexcitability of sensory neurons induced by local DRG inflammation observed 4 d later. Microsympathectomy reduced local inflammation and macrophage density in the affected tissues (as indicated by paw swelling and histochemical staining). Cytokine profiling in locally inflamed DRG showed increases in pro-inflammatory Type 1 cytokines and decreases in the Type 2 cytokines present at baseline, changes that were mitigated by microsympathectomy. Microsympathectomy was also effective in reducing established pain behaviors in the local DRG inflammation model. We conclude that the effect of sympathetic fibers in the L4/L5 gray rami in these models is pro-inflammatory. This raises the possibility that therapeutic interventions targeting gray rami might be useful in some chronic inflammatory pain conditions. SIGNIFICANCE STATEMENT Sympathetic blockade is used for many pain conditions, but preclinical studies show both pro- and anti-nociceptive effects. The sympathetic nervous system also has both pro- and anti-inflammatory effects on immune tissues and cells. We examined effects of a very localized sympathectomy.

There is limited knowledge of the foot lesions that influence the outcome of palmar/plantar digital neurectomy (PDN). 1) To report the short- and long-term outcomes of horses that underwent PDN to alleviate chronic foot pain due to lesions diagnosed by magnetic resonance imaging (MRI) and 2) factors that may influence the outcome of PDN. Multicentre retrospective study. Medical records of 50 horses subjected to PDN due to chronic foot pain were reviewed. Age, breed, sex, athletic activity, duration of lameness, affected limb(s), response to anaesthesia of the palmar/plantar digital nerves, MRI findings and surgical technique were analysed together with follow-up data to identify factors that influenced the long-term outcomes. Forty-six of 50 horses (92%) responded positively to surgery; 40 (80%) were able to return to their previous athletic use for a median time of 20 months (range: 12-72 months). Eighteen (36%) horses developed post operative complications including residual lameness, painful neuromas, or early recurrence of lameness. Horses with pre-existing core or linear lesions of the deep digital flexor tendon (DDFT) had significantly shorter periods of lameness resolution after surgery than horses with dorsal border lesions of the DDFT or other foot lesions. Palmar/plantar digital neurectomy can improve or resolve lameness in horses with foot pain unresponsive to medical therapy without serious post operative complications. However, horses with core or linear lesions of the DDFT should not be subjected to PDN as these horses experience residual lameness or early recurrent lameness after surgery. Magnetic resonance imaging can be used to identify these horses. © 2014 EVJ Ltd.

Emergency management of traumatic collateral palmar digital nerve defect inferior to 30 mm by venous grafting. Report of 12 clinical cases.

When traumatic collateral palmar digital nerve defect occurs, emergency venous grafting is an alternative to the two-step nervous grafting procedure. During the course of a monocentric retrospective study, 12 cases of emergency venous grafting were reviewed by a single independent examiner 11 months, at least, post-intervention. Clinical and functional evaluation was carried out, together with a self-assessment of the results by the patient. Data were compacted using a filtering method and the final result was considered in terms of "good" or "bad". Good result was observed in ten cases out of 12. Bad results were associated with poor sensory recovery in the two other cases. In one of these, the bad result was also related to severe symptoms in cold conditions and a troublesome hyperesthesia. Through a review of the literature, we justify the emergency treatment of nerve defects of the collateral palmar digital nerves with venous grafting. Copyright © 2010 Elsevier Masson SAS.

To report the results of a technique of soft tissue stabilization for palmar midcarpal instability using a palmaris longus graft. In patients' symptomatic wrists with palmar midcarpal instability that had failed conservative management, we used a dorsal approach and stabilized the hamate and triquetrum by reconstructing the dorsal triquetrohamate ligament. The palmaris longus tendon graft was fixed with bone anchors. Seven wrists in 6 patients were available for follow-up at a mean of 28 months (range, 17-37 mo). There was an overall meaningful improvement in function (mean preoperative Disabilities of the Arm, Shoulder, and Hand score, 49 preoperatively, 28 postoperatively). There was a significant increase in grip strength from 15 to 21 kg. At final follow-up, 2 patients had moderate pain. The others had mild or no pain. Four patients returned to their previous occupation or activity. Patients retained full pronation and supination. When compared with the normal side, flexion was reduced to 71%, extension to 81%, radial deviation to 90%, and ulnar deviation to 65% of the opposite side. Although the mean results show an improvement, one patient had a poor result with deterioration in Disabilities of the Arm, Shoulder, and Hand score in spite of a clinically stable wrist, and another had clinical evidence of recurrent instability during pregnancy. One patient had residual symptoms from a prominent bone anchor. Overall, this technique showed good medium-term results in most of our patients. It retained some midcarpal mobility, eliminated clunking in most patients, and provided a noteworthy improvement in grip strength and function. We continue to use this technique for patients with symptomatic midcarpal instability, but it requires further evaluation with larger patient numbers and a longer follow-up to assess its overall value.

Evidence-based information is limited on distribution of local anaesthetic solution following perineural analgesia of the palmar (Pa) and palmar metacarpal (PaM) nerves in the distal aspect of the metacarpal (Mc) region ('low 4-point nerve block'). To demonstrate the potential distribution of local anaesthetic solution after a low 4-point nerve block using a radiographic contrast model. A radiodense contrast medium was injected subcutaneously over the medial or the lateral Pa nerve at the junction of the proximal three-quarters and distal quarter of the Mc region (Pa injection) and over the ipsilateral PaM nerve immediately distal to the distal aspect of the second or fourth Mc bones (PaM injection) in both forelimbs of 10 mature horses free from lameness. Radiographs were obtained 0, 10 and 20 min after injection and analysed subjectively and objectively. Methylene blue and a radiodense contrast medium were injected in 20 cadaver limbs using the same techniques. Radiographs were obtained and the limbs dissected. After 31/40 (77.5%) Pa injections, the pattern of the contrast medium suggested distribution in the neurovascular bundle. There was significant proximal diffusion with time, but the main contrast medium patch never progressed proximal to the mid-Mc region. The radiological appearance of 2 limbs suggested that contrast medium was present in the digital flexor tendon sheath (DFTS). After PaM injections, the contrast medium was distributed diffusely around the injection site in the majority of the limbs. In cadaver limbs, after Pa injections, the contrast medium and the dye were distributed in the neurovascular bundle in 8/20 (40%) limbs and in the DFTS in 6/20 (30%) of limbs. After PaM injections, the contrast and dye were distributed diffusely around the injection site in 9/20 (45%) limbs and showed diffuse and tubular distribution in 11/20 (55%) limbs. Proximal diffusion of local anaesthetic solution after a low 4-point nerve block is unlikely to be

Chronic arsenical intoxication can still be found in environmental and industrial settings. Symptoms of chronic arsenic intoxication include general pigmentation or focal "raindrop" pigmentation of the skin and the appearance of hyperkeratosis of the palms of the hands and soles of the feet. In addition to arsenic-related skin diseases including keratosis, Bowen's disease, basal-cell-carcinoma, and squamous-cell carcinoma, there is also an increased risk of some internal malignancies. Arsenic-related diseases are common in areas of the world where the drinking water has a high arsenic content. In this paper, we describe a 35-year-old male patient who had arsenic-related keratosis, squamous-cell carcinoma in the palmar area of his left hand, and Bowen's disease on his left thigh. The patient worked in a borax mine for 15 years, so he was exposed to arsenic in drinking water, airborne arsenic in his workplace, and had direct contact. The patient was treated for 11 months for arsenic-related keratosis until an axillary lymph node metastasis occurred; the lesion was excised and diagnosed to be malignant. Bowen's disease was detected when the patient was being treated for cancer. No other malignancy was found. The patient is still receiving regular follow-up care.

This research was made in order to find out if there is an inherited component which determines the features of dermatoglyphics by transmitting inherited information from parents to children. The article shows the results of a research into 22 quantitative features of the digito-palmar complex, and 2 features of the plantar area in 400 persons. No significant differences were found in the parameters of the observed variables between fathers and sons, nor mothers and daughters. The differences were found, however, between fathers and daughters, and mothers and sons. The analysis of the correlation coefficients within the families showed that only the variables TRC and TPRC have polygenic hereditary model. The correlative analyses have shown close links between parents and children, the link between parents and sons being stronger than the link between parents and daughters. The research has not confirmed the thesis about greater overlap between mother and children, than between father and children, set forth by Knussmann in 1973.

High-dose cytarabine is recommended for re-induction chemotherapy in patients less than 60 years of age with acute myelogenous leukemia. This case describes a patient receiving high-dose cytarabine for re-induction and subsequently developed tingling and numbness in her hands and feet followed by severe pain, swelling, and erythema consistent with a diagnosis of palmar-plantar erythrodysesthesia. Furthermore, the patient's hemoglobin, platelets, and neutrophils did not recover after over 30 days post high-dose cytarabine. The patient was concurrently receiving posaconazole for fungal prophylaxis which was initiated after the induction therapy. We speculate that posaconazole may inhibit the cytarabine efflux through P-glycoprotein inhibition leading to the patient's palmar-plantar erythrodysesthesia and subsequent aplasia. Future pharmacokinetic studies need to be conducted to ascertain if posaconazole does influence the pharmacokinetics of cytarabine.

There are conflicting data about the correlation between hyperhidrosis (HH) and anxiety and depression. We sought to determine the prevalence of anxiety and depression in patients with or without HH. We examined 2017 consecutive dermatology outpatients from Vancouver, British Columbia, Canada, and Shanghai, China, using Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 scales for anxiety and depression assessments. Multivariable logistic regression analysis was performed to evaluate if the impact of HH on anxiety and depression is dependent on demographic factors and diagnoses of the patients' presenting skin conditions. The prevalence of anxiety and depression was 21.3% and 27.2% in patients with HH, respectively, and 7.5% and 9.7% in patients without HH, respectively (P value <.001 for both). There were positive correlations between HH severity and the prevalence of anxiety and depression. Multivariable analysis showed that HH-associated increase in anxiety and depression prevalence is independent of demographic factors and presenting skin conditions. The data from the questionnaires relied on the accuracy of patients' self-reports. Both single variant and multivariable analyses showed a significant association between HH and the prevalence of anxiety and depression in a HH severity-dependent manner.

The aim of this study was to determine whether horses with a proximal palmar/plantar first phalangeal osteochondral fragment (POF) had comparable racing careers (prior to and following surgery) to horses without this fracture. A retrospective cohort study included 174 Swedish Standardbred trotters with osteochondral fragmentation in the palmar/plantar fetlock joint and 613 radiographically negative control horses presented for prepurchase examinations. Medical records and radiographs were examined for each horse. Racing data were retrieved from online Swedish Standardbred harness racing records. The effect of having a POF on race speed compared to radiographically negative control horses was examined using generalised estimating equations. Multivariable regression was used to examine differences in money earned and career longevity. The horses raced a total of 16,448 races. Horses gained speed as a function of race number. There was no difference in racing speed between horses with POF fractures that raced before surgery and control horses. Horses did not slow before, nor speed up after, surgery. There was no difference in the number of days between the last race prior to, or the first race after, the hospital visit between POF and control horses. Career earnings and lifetime starts were not significantly different between groups. The results of this study suggest the need to reevaluate the previously reported benefits of surgical intervention for POF. Copyright © 2014 Elsevier Ltd. All rights reserved.

Over the past 10 years primary, secondary and tertiary prevention of occupational skin disorders has been shown to be successful, documented with appropriate statistical methods. Interventional strategies are the main features of secondary and tertiary prevention, now well-established in occupational dermatology. Primary prevention is best accomplished by health education measures, both in the form on individual counseling and seminars. This overview reviews the scientific background of hand eczema with respect to barrier damage and repair and then considers the options for individualized and focused prevention. Special anatomical features of the interdigital space and palms, as well as functional disorders, such as palmar hyperhidrosis, are discussed. The importance of barrier regeneration is considered in light of the role of an acid pH, the epidermal calcium gradient and aspects of percutaneous absorption. The effects of anti-oxidants are considered, and new bioengineering methods which rely on physiologic measuring techniques are reviewed.

To demonstrate feasibility of vessel wall imaging of the superficial palmar arch using high frequency micro-ultrasound, 7T and 3T magnetic resonance imaging (MRI). Four subjects (ages 22-50 years) were scanned on a micro-ultrasound system with a 45-MHz transducer (Vevo 2100, VisualSonics). Subjects' hands were then imaged on a 3T clinical MR scanner (Siemens Biograph MMR) using an 8-channel special purpose phased array carotid coil. Lastly, subjects' hands were imaged on a 7T clinical MR scanner (Siemens Magnetom 7T Whole Body Scanner) using a custom built 8-channel transmit receive carotid coil. All three imaging modalities were subjectively analyzed for image quality and visualization of the vessel wall. Results of this very preliminary study indicated that vessel wall imaging of the superficial palmar arch was feasible with a whole body 7T and 3T MRI in comparison with micro-ultrasound. Subjective analysis of image quality (1-5 scale, 1: poorest, 5: best) from B mode, ultrasound, 3T SPACE MRI and 7T SPACE MRI indicated that the image quality obtained at 7T was superior to both 3T MRI and micro-ultrasound. The 3D SPACE sequence at both 7T and 3T MRI with isotropic voxels allowed for multi-planar reformatting of images and allowed for less operator dependent results as compared to high frequency micro-ultrasound imaging. Although quantitative analysis revealed that there was no significant difference between the three methods, the 7T Tesla trended to have better visibility of the vessel and its wall. Imaging of smaller arteries at the 7T is feasible for evaluating atherosclerosis burden and may be of clinical relevance in multiple diseases.

Power-assistive finger exoskeleton with a palmar opening at the fingerpad.

PubMed

Heo, Pilwon; Kim, Jung

2014-11-01

This paper presents a powered finger exoskeleton with an open fingerpad, named the Open Fingerpad eXoskeleton (OFX). The palmar opening at the fingerpad allows for direct contact between the user's fingerpad and objects in order to make use of the wearer's own tactile sensation for dexterous manipulation. Lateral side walls at the end of the OFX's index finger module are equipped with custom load cells for estimating the wearer's pinch grip force. A pneumatic cylinder generates assistance force, which is determined according to the estimated pinch grip force. The OFX transmits the assistance force directly to the objects without exerting pressure on the wearer's finger. The advantage of the OFX over an exoskeleton with a closed fingerpad was validated experimentally. During static and dynamic manipulation of a test object, the OFX exhibited a lower safety margin than the closed exoskeleton, indicating a higher ability to adjust the grip force within an appropriate range. Furthermore, the benefit of force assistance in reducing the muscular burden was observed in terms of muscle fatigue during a static pinch grip. The median frequency (MDF) of the surface electromyography (sEMG) signal from the first dorsal interosseous (FDI) muscle displayed a lower reduction rate for the assisted condition, indicating a lower accumulation rate of muscle fatigue.

Role of linoleic acid in arsenical palmar keratosis.

2016-03-01

Chronic arsenic exposure can lead to palmoplantar keratosis. In the stratum corneum of skin, linoleic acid is of the utmost importance to the inflammation, keratinization, and regeneration processes. The aims of this study were: (i) to present quantitative information on the linoleic acid fraction of intercorneocyte lipids, and (ii) to elucidate the role of linoleic acid in the pathophysiology of arsenical keratosis. Lipid extracts were collected from keratotic lesions in seven patients, seven arsenic-exposed subjects, and seven non-exposed control subjects. Linoleic acid levels of the specimens were estimated by reverse-phase high-performance liquid chromatography (RP-HPLC). There was a significant (P < 0.001) increase in mean ± standard error (SE) linoleic acid levels in arsenical keratosis patients (palm: 25.66 ± 4.95 μg/cm(2); dorsum: 28.25 ± 6.20 μg/cm(2)) compared with arsenic-exposed (palm: 2.75 ± 0.85 μg/cm(2); dorsum: 1.96 ± 0.64 μg/cm(2)) and non-exposed (palm: 1.52 ± 0.61 μg/cm(2); dorsum: 1.28 ± 0.39 μg/cm(2)) control subjects. There was no significant difference (P = 0.556) in linoleic acid concentration in the non-affected skin of the dorsum of the hand (28.25 ± 6.20 μg/cm(2)) compared with that in the palmar sites (25.66 ± 4.95 μg/cm(2)) in the patient group. The change in linoleic acid levels in the arsenic-exposed control group did not differ from that in non-exposed controls (P = 1.000). Linoleic acid concentration is elevated in arsenical keratosis; this finding warrants further investigation to ascertain whether linoleic acid plays a direct role in the pathophysiology of arsenical keratosis. © 2015 The International Society of Dermatology.

Composition and structure of arbuscular-mycorrhizal communities in El Palmar National Park, Argentina.

Velázquez, María S; Cabello, Marta N; Barrera, Marcelo

2013-01-01

The arbuscular-mycorrhizal-fungal (AMF) communities from the El Palmar National Park of Entre Ríos Province, Argentina, were investigated and characterized. The species of AMF present in five distinct vegetation types-gallery forest, grassland, marsh, palm forest, and scrubland-were isolated, identified and quantified over 2 y. Forty-six AMF morphotaxa were found. The composition of the AMF communities differed between the seasons, soil and vegetation types. Seasonal variations were observed in members of the Acaulosporaceae, Archaeosporaceae, Claroideoglomeraceae, Gigasporaceae and Pacisporaceae. Depending on soil type, the AMF-spore communities were dominated by members of one of the two main orders of the Glomeromycota. AMF communities from grassland and palm forest, which occur on sandy soils, comprised primarily members of the Diversisporales, with a high percentage of species of Acaulospora and of Gigasporaceae. Communities from the gallery forest, marsh and scrubland, which occur on loam-clay soils, were composed of members of the Glomerales, with a high percentage of spores from species of Glomus. Thus, both AMF and plant communities would appear to be strongly and similarly influenced by edaphic conditions.

Alefacept is safe and efficacious in the treatment of palmar plantar pustulosis.

PubMed

Guenther, Lyn C

2007-01-01

Alefacept blocks T-cell activation and induces apoptosis of memory T cells. It improves psoriasis vulgaris and may induce prolonged remissions. Experience with alefacept in palmar plantar pustulosis (PPP) is limited. The objective of the study was to observe the effectiveness and safety of alefacept in the treatment of PPP. Alefacept was administered weekly for 16 weeks by intramuscular (IM) injection of 15 mg to 15 patients with moderate to very severe PPP. Patients were followed for an additional 12 weeks. Four weeks after 16 weeks of treatment, there was a 49.6% reduction in the Palmoplantar Pustulosis Psoriasis Area and Severity Index (PPPASI) and a 38.6% and a 64.5% reduction in total and fresh pustules, respectively. Eight weeks after dosing, 53.3% achieved PPPASI 50, 26.7% achieved PPPASI 75, and one patient was clear. The mean percent reduction in total pustules and fresh pustules was 46.1% and 61.2%, respectively; 73% had no pain, 53% had no itching, and 80% had no functional impairment. The palms responded better than the soles. This pilot showed that 16 weeks of once-weekly alefacept 15 mg IM was safe, led to improvement in PPP in all 15 treated patients, and induced a remission in one patient. Larger double-blind studies are warranted.

To determine the prevalence of fingerprint verification failure and to define and quantify the fingerprint changes associated with fingerprint verification failure. Case-control study. Referral public dermatology center. The study included 100 consecutive patients with clinical hand dermatitis involving the palmar distal phalanx of either thumb and 100 age-, sex-, and ethnicity-matched controls. Patients with an altered thumb print due to other causes and palmar hyperhidrosis were excluded. Fingerprint verification(pass/fail) and hand eczema severity index score. Twenty-seven percent of patients failed fingerprint verification compared with 2% of controls. Fingerprint verification failure was associated with a higher hand eczema severity index score (P.001). The main fingerprint abnormalities were fingerprint dystrophy (42.0%) and abnormal white lines (79.5%). The number of abnormal white lines was significantly higher among the patients with hand dermatitis compared with controls(P=.001). Among the patients with hand dermatitis, theodds of failing fingerprint verification with fingerprint dystrophy was 4.01. The presence of broad lines and long lines was associated with a greater odds of fingerprint verification failure (odds ratio [OR], 8.04; 95% CI, 3.56-18.17 and OR, 2.37; 95% CI, 1.31-4.27, respectively),while the presence of thin lines was protective of verification failure (OR, 0.45; 95% CI, 0.23-0.89). Fingerprint verification failure is a significant problem among patients with more severe hand dermatitis. It is mainly due to fingerprint dystrophy and abnormal white lines.

Several lines of evidence indicate that the sympathetic nervous system (SNS) might be involved in the pathogenesis and progression of retroviral infections. However, experimental data are scarce and findings inconsistent. Here, we investigated the role of the SNS during acute infection with Friend virus (FV), a pathogenic murine retrovirus that causes polyclonal proliferation of erythroid precursor cells and splenomegaly in adult mice. Experimental animals were infected with FV complex, and viral load, spleen weight, and splenic noradrenaline (NA) concentration was analyzed until 25 days post infection. Results show that FV infection caused a massive but transient depletion in splenic NA during the acute phase of the disease. At the peak of the virus-induced splenomegaly, splenic NA concentration was reduced by about 90% compared to naïve uninfected mice. Concurrently, expression of the catecholamine degrading enzymes monoamine oxidase A (MAO-A) and catechol-O-methyltransferase (COMT) was significantly upregulated in immune cells of the spleen. Pharmacological inhibition of MAO-A and COMT by the selective inhibitors clorgyline and 3,5-dinitrocatechol, respectively, efficiently blocked NA degradation and significantly reduced viral load and virus-induced splenomegaly. In contrast, chemical sympathectomy prior to FV inoculation aggravated the acute infection and extended the duration of the disease. Together these findings demonstrate that catecholamine availability at the site of viral replication is an important factor affecting the course of retroviral infections.

The main aim of the present paper is to describe the first Detarioideae fossil woods from El Palmar Formation (Late Pleistocene) in the Uruguay River Basin (Entre Ríos, Argentina). This study is based on five silicified wood specimens preserved in fluvial deposits, which were transported from their growth site. Two new genera and species are described: Paraoxystigma concordiensis gen. nov and sp. nov. has medium-sized vessels, paratracheal axial parenchyma, heterocellular and multiseriate rays, and diffuse axial canals similar in size and shape to vessels, and Gossweilerodendroxylon palmariensis gen. nov and sp. nov. has medium-sized vessels, alternate intervessel pits, paratracheal and apotracheal axial parenchyma, homocellular and uni to-multiseriate rays, and small diffuse axial canals. These Detarioideae fossil records in south-eastern South America support the existence of a very old relationship with the extant West African forests. Eco-anatomical features observed in these fossil woods, along with the climatic information available from the Nearest Living Relatives (NLRs) comparison, suggest warm and humid climatic conditions for the upper-middle basin of the Uruguay River during some periods of the Late Pleistocene.

To investigate the effectiveness of the island flaps based on the superficial palmar branch of the radial artery (SPBRA) to repair the thumb wound. Between February 2012 and November 2013, 8 cases of thumb defects and bilateral artery defect were treated. There were 5 males and 3 females with an average age of 30.5 years (range, 19-51 years). The injury was caused by crush (4 cases), avulsion (3 cases), and twist (1 case). The injury located at the metacarpophalangeal joints in 3 cases, at the proximal palmar side in 2 cases, and at the interphalangeal joints in 3 cases. The defect size ranged from 3.5 cm x 1.5 cm to 6.5 cm x 2.0 cm. The digital artery defect was 2.5-8.5 cm (mean, 5.3 cm). The disease duration was 2.0-4.5 hours (mean, 3.2 hours). The reversed island flaps based on the SPBRA were designed, which size was 4.0 cm x 2.0 cm to 7.5 cm x 3.0 cm. The donor sites were closed directly. The operation was successfully completed in 7 patients except 1 patient having vascular variation. All flaps survived completely. Wound and incision at the donor site healed by first intention. All patients were followed up 6-18 months (mean, 13 months). The flaps had similar color and texture to adjacent skin. Linear scar was seen at the donor site in 1 patient, with no functional limitation. According to the functional assessment criteria of upper limb by the Hand Surgery Branch of Chinese Medical Association, the results were excellent in 6 cases, good in 1 case, and fair in 1 case, with an excellent and good rate of 87.5%. The reversed island flap based on the SPBRA is an ideal flap for the thumb reconstruction because the advantages of reliable blood supply, easy dissection, less injury at donor site, and good repair results.

Previous studies have established the role of quantitative measurements of palmar abduction strength of the thumb (PAST). This study compares the reliability of the 'make' versus the 'break' test in measuring PAST in healthy volunteers. In a 'make' test, the body part being tested is positioned at the start of its range of motion and the participant is asked to exert his/her maximal force. In a 'break' test, increasing force is applied to a body part after it has completed its range of motion, until the joint being tested gives way. PAST was measured in both hands in 100 healthy volunteers using a handheld device. Two examiners measured PAST using both the 'make' and 'break' test to determine inter-rater reliability. The tests were repeated in 30 volunteers 6 weeks after the initial testing to determine intra-rater reliability. Our results showed that the 'make' test has better inter and intra-rater reliability.

Purpose Palmar-plantar erythrodysethesia (PPE) is a common chemotherapy and anti-VEGF multi-kinase inhibitor class-related toxicity that often results in debilitating skin changes and often limits the use of active anti-cancer regimens. Mechanistic and anecdotal clinical evidence suggested that topical application of sildenafil cream may help reduce the severity of PPE. Therefore, we conducted a randomized, double-blind, placebo-controlled pilot study to evaluate the feasibility, safety and efficacy of topical sildenafil cream for the treatment of PPE. Methods Eligible subjects were required to have grade 1–3 PPE associated with either capecitabine or sunitinib. Subjects were randomized to receive 1% topical sildenafil cream to the left extremities or right extremities and placebo cream on the opposite extremity. 0.5 mL of cream was applied to each affected hand/foot two times per day. The primary endpoint was improvement in PPE grading at any point on study. Clinical assessments were evaluated by NCI-CTC 4.0 grading and patient self-reported pain. Results Ten subjects were enrolled; 9 were evaluable for safety and efficacy. Five of nine subjects reported some improvement in foot pain and 3 of 8 subjects for hand pain improvement. One of these subjects noted specific improvement in tactile function. No treatment-related toxicities were observed. Conclusions In this limited, single center study, topical cream containing 1% sildenafil is feasible to administer, is well-tolerated, and may mitigate PPE-related symptoms due to anti-cancer therapeutic agents. Further validation is necessary. PMID:25341548

Nowadays insight into human-machine interaction is a critical topic with the large-scale development of intelligent vehicles. Biosignal analysis can provide a deeper understanding of driver behaviors that may indicate rationally practical use of the automatic technology. Therefore, this study concentrates on biosignal analysis to quantitatively evaluate mental stress of drivers during automatic driving of trucks, with vehicles set at a closed gap distance apart to reduce air resistance to save energy consumption. By application of two wearable sensor systems, a continuous measurement was realized for palmar perspiration and masseter electromyography, and a biosignal processing method was proposed to assess mental stress levels. In a driving simulator experiment, ten participants completed automatic driving with 4, 8, and 12 m gap distances from the preceding vehicle, and manual driving with about 25 m gap distance as a reference. It was found that mental stress significantly increased when the gap distances decreased, and an abrupt increase in mental stress of drivers was also observed accompanying a sudden change of the gap distance during automatic driving, which corresponded to significantly higher ride discomfort according to subjective reports.

Hyperhidrosis can be subdivided into generalized hyperhidrosis, with increased sweating over the entire body, and focal hyperhidrosis, in which the excessive sweating is restricted to specific parts of the body. Generalized hyperhidrosis may be either primary (idiopathic) or secondary. Secondary generalized hyperhidrosis may be caused by infections such as tuberculosis, hyperthyroidism, endocrine and metabolic disturbances such as pheochromocytoma, neurological disorders, or drugs. Focal hyperhidrosis may also be primary (idiopathic) or secondary. Frey's syndrome is one form of secondary focal hyperhidrosis that occurs during eating together with reddening of the area in front of the ear following parotid gland surgery or injury. Primary focal hyperhidrosis is particularly common on the palms and soles of the feet, in the axilla, and on the head. Anhidrosis may be either congenital/genetic or acquired. Some of the most typical forms of congenital/genetic anhidrosis include hypohidrotic ectodermal dysplasia, congenital insensitivity to pain and anhidrosis, and Fabry disease. Acquired anhidrosis is classified as secondary anhidrosis, which may be due to an underlying disorder such as a neurological disorder, an endocrine or metabolic disturbance, or the effect of drugs, or idiopathic anhidrosis for which the pathology, cause, and mechanism are unknown. Idiopathic anhidrosis is classified into acquired idiopathic generalized anhidrosis (AIGA), idiopathic segmental anhidrosis, and Ross syndrome. AIGA is divided into three categories according to differences in the site of disturbance: (1) sudomotor neuropathy, (2) idiopathic pure sudomotor failure, and (3) sweat gland failure. © 2016 S.

This report presents a case of post-burn palmar contracture with flexion contracture of thumb of 20-year duration. The contracture was released and the raw area was covered with split thickness skin graft. Only one 'K' wire in soft tissue was needed to keep all the fingers straight and immobilized, suggestive of intermetacarpal ligamentous contracture. A static night splint was given to maintain the correction. Complete range of movement was achieved in a month with the combination of dynamic splinting and physiotherapy. It was interesting to note that even 20 years of contracted position did not render the metacarpophalangeal joints completely stiff and useless. Probable reasons are discussed.

Child palm burns arise by contact and are often deep. The singular difficulty of such a disease comes from the necessity of the child growth and from the potential occurrence of constricted scars. In order to avoid sequelae, the actual gold standard is to practice an early excision of the burn, followed by a skin graft. The aim of this study is to evaluate the results of spontaneous healing combined with rehabilitation versus early skin grafting and rehabilitation concerning the apparition of sequelae. We performed a retrospective study in two burn centers and one rehabilitation hospital between 1995 and 2010. Eighty-seven hands have been included in two groups: one group for spontaneous healing and the other group for excision and skin grafting. Every child benefited from a specific rehabilitation protocol. The two main evaluation criteria were the duration of permanent splint wearing and the number of reconstructive surgery for each child. The median follow-up duration is about four years. The two groups were comparable. For the early skin grafting group, the splint wearing duration was 1/3 longer than for the spontaneous healing group. Concerning the reconstructive surgery, half of the grafted hands needed at least one procedure versus 1/5 of spontaneous healing hands. Our results show the interest of spontaneous healing in palmar burn in child, this observation requires a specific and intense rehabilitation protocol. Copyright © 2016 Elsevier Masson SAS.

Palmar-plantar erythrodysesthesia (PPE) or hand-foot syndrome (HFS) is a relatively common side effect of cytotoxic chemotherapy. Many cytotoxic drugs have been reported to cause the condition but it is more frequently associated with 5 fluorouracil (5FU), liposomal doxorubicin and cytarabine. The oral 5FU precursor, capecitabine is frequently associated with PPE and with the recent extension of its use to adjuvant treatment, the incidence of PPE is likely to increase. The initial symptoms are dysesthesia and tingling in the palms, fingers and soles of feet and erythema, which may progress to burning pain with dryness, cracking, desquamation, ulceration and oedema. Palms of the hands are more frequently affected than soles of the feet. This condition is painful and distressing to patients and in some incidences it results in patients not being able to work or perform normal daily activities. It can also result in treatment interruptions which impact on the efficacy of the treatment regimen. Effective and appropriate patient education from a specialist nurse prior to treatment is an essential part of patient management which will facilitate early identification of the symptoms and therefore prevent treatment delays and PPE progression. This article reviews current knowledge of the condition, including classification, and discussion of the findings of a clinical audit in a cancer centre. It includes the incidence, grading, management and impact of PPE on normal daily activities.

Following reports of linkage close to the keratin gene cluster in families with tylosis and the detection of mutations in the keratin 9 gene cosegregating in families with epidermolytic palmar plantar keratoderma (EPPK, and EPPK associated with breast and ovarian cancer), we have identified families with three phenotypically distinct forms of non-epidermolytic keratosis with either punctate, diffuse or focal keratoderma, one with diffuse lesions and one with punctate and malignancies. Initially we typed these families with 17q markers close to the keratin gene cluster; this included a dinucleotide repeat marker within the keratin 9 gene. Two point linkage analysis ofmore » the focal keratoderma family showed a positive lod score of 3.2 at a theta of 0 from the marker D17S855. The lod score for the diffuse family was -6.0 at a theta of 0.05 from the marker D17S776. The second focal keratoderma family showed a haplotype consistent with linkage to 17q close to the keratin gene cluster. A second keratin gene cluster has been mapped in humans on 12q, and we decided to test the unlinked diffuse and punctate keratoderma families with markers in that region. We used the markers: D12S87-D12S85-D12S368-D12S96-D12S90. Linkage analysis of the diffuse family gave a lod score of 3.1 at a theta of 0 from the marker D12S368. Currently studies are underway to look for mutations in specific keratin genes in the clusters on 17q and 12q that segregate with the observed phenotypes. The punctate keratoderma family gave lod scores of -3.9 at a theta of 0.55 with D17S855 and -6.0 at a theta of 0.05 with D12S90/D12S83. This would lead us to the conclusion that a separate susceptibility locus must exist for the punctate family associated with malignancy. Investigations of candidate regions are in progress.« less

Nearly 3% of the population has hyperhidrosis. Quality of life is affected, impacting on social relationships and professional activity, and social anxiety disorder can sometime develop. We review the definition and causes of hyperhidrosis and the clinical evaluation of patients. After describing the different clinical aspects of the condition, we discuss the medical and surgical treatments. Of such treatments currently available, particular mention is made of the use of botulinum toxin in some forms of hyperhidrosis as an intermediate option between the traditional treatments and surgery. We also draw attention to the use of minimal access surgical techniques (videothoracoscopy), which, over the past decade, have become established as an effective, safe, and permanent approach for the treatment of hyperhidrosis when indicated.

Fibrocartilage degeneration is the earliest pathologic finding in navicular disease but remains difficult to detect, even with magnetic resonance (MR) imaging. We hypothesized that injection of the navicular bursa with saline would improve accuracy of MR imaging evaluation of palmar fibrocartilage. Thoracic limbs were collected from 11 horses within 6 h of death. Imaging was performed with a 1.5 T magnet using sagittal 2D proton density and transverse 3D FLASH sequences with fat saturation. For the purpose of determining sensitivity and specificity of the MR images, fibrocartilage was classified as normal or abnormal, based on combination of the findings of gross and microscopic pathology. Thickness of fibrocartilage was measured on histologic sections and corresponding transverse FLASH MR images before and after injection of saline. A paired Student's t-test was used for comparison of measurements. Partial thickness fibrocartilage loss was present in 6 of 22 limbs. Sensitivity of precontrast MR images for detection of lesions was 100% while specificity was 6%. Saline MR arthrography resulted in both sensitivity and specificity of 100% based on consensus review. Mean histologic fibrocartilage thickness was 0.75 +/- 0.12 mm. Mean fibrocartilage thickness on precontrast transverse FLASH images was 0.93 +/- 0.065 and 0.73 +/- 0.09 mm on postsaline images. The histologic cartilage thickness was signficantly different from that in precontrast images (P<0.001) but not in images acquired after saline injection (P = 0.716). Based on our results, and using pulse sequences as described herein, navicular fibrocartilage can only be evaluated reliably for the presence of partial thickness lesions after intrabursal injection of saline.

Accessory triradii and the atd angle were examined via complex segregation analysis in order to evaluate possible genetic effects on these dermatoglyphic traits, measured in an endogamous Brahmin caste of peninsular India. The phenotypes considered included: presence of accessory palmar triradii a' and d', associated with the interdigital areas II and IV, respectively; presence of an accessory axial triradius tt' associated with the proximal margin of the palm; and an arctanh-transformation of the atd angle measurement. For all accessory triradii considered in the present investigation familial resemblance was evident. The most parsimonious model which could account for the observed resemblance was a multifactorial model that includes polygenic effects as well as transmissible environmental effects that are inherited in the same pattern as polygenes. Evidence of familial resemblance was also found for the arctanh-transformed atd angle, which could be attributed, initially, to both a major effect and a multifactorial component. Tests of transmission of a putative major gene were performed which yielded results consistent with Mendelian transmission, although an alternative test of no transmission of the major effect also fit the data. In light of these contrasting results we are precluded from accepting with confidence the notion of a major gene influence on the atd angle. We have concluded that the accessory triradii a', d', and tt', and the atd angle are influenced by multifactorial effects, including additive polygenes and possible environmental factors, such as intrauterine effects.

Palmar-plantar erythrodysesthesia syndrome (PPES) is an uncommon side effect of high-dose cytarabine or methotrexate. Prior case reports of PPES have been limited, and the predisposing factors for the development of PPES remain unknown. A review of databases identified 22 patients (1.3%) who developed 39 episodes of PPES among 1720 patients after treatment with high-dose cytarabine or methotrexate. Symptoms lasted a mean of 6.4 days. Hands and feet were both involved in 68% of the initial episodes. Parenteral opioids were required for pain control by 27% of the patients. In comparison with the 1698 children treated with similar therapy, the children who developed PPES were older (mean age at diagnosis, 14.3 vs 7.7 years; P = 7.5 × 10 -7 ). The frequency of PPES was less common in patients receiving methotrexate alone (7 of 946 or 0.7%) versus cytarabine (7 of 205 or 3.4%; P = .005) but was not different for those receiving both high-dose methotrexate and cytarabine (8 of 569 or 1.4%; P = .32). Prolonged infusions of methotrexate were associated with less frequent PPES in comparison with rapid infusions (P = 1.5 × 10 -5 ), as was the co-administration of dexamethasone with cytarabine (P = 2.5 × 10 -6 ). Self-described race and sex were not associated with PPES. In a multivariate analysis, older age and high-dose cytarabine administration without dexamethasone remained associated with PPES (P = 1.1 × 10 -4 and P = .038, respectively). A genome-wide association study did not identify any associations with PPES meeting the genome-wide significance threshold, but top variants were enriched for skin expression quantitative trait loci, including rs11764092 in AUTS2 (P = 6.45 × 10 -5 ). These data provide new insight into the incidence of PPES as well as its risk factors. Cancer 2017;123:3602-8. © 2017 American Cancer Society. © 2017 American Cancer Society.

To investigate the results of resurfacing completely degloved digits using bilobed innervated radial artery superficial palmar branch (RASPB) perforator flap in a spiral fashion. A detailed anatomic study on 30 adult fresh frozen cadavers preinjected with silicone rubber compound to demarcate arterial anatomy documented locations, numbers, and diameters of arteries and skin perforators with surrounding nerves. The flap-raising procedure was performed using four fresh cadaver specimen. We reviewed the reconstruction of 12 digits by using a bilobed spiraled innervated RASPB free perforator flap after non-replantable degloving injury. Two skin paddles were marked out using standard points of reference. At least two separate cutaneous perforator vessels were identified using a hand-held Doppler and were dissected back to the RASPB in retrograde fashion. The skin paddles were then divided between the two cutaneous perforators to provide two separate paddles with a common vascular supply. The skin paddles were stacked in a spiral fashion on the flap inset, effectively increasing the width of the flap to cover the totally degloved finger while still allowing closure of the primary donor-site. The RASPB was present within the flap in all cadavers. The direct perforator and the musculocutaneous perforator were available in 93.33 and 76.67 %, respectively, with neither of them in 6.67 % of the cases. The constantly present two perforators allowed the design of a new bilobed spiraled innervated radial artery superficial palmar branch perforator flap. We used the proposed flap to reconstruct completely degloved digits in 12 patients (mean age 28.6 years; range 17-35 years). With our proposed flap, no flap failure or re-exploration occurred and the donor site was closed primarily in all cases. All the flaps survived uneventfully. Total active motion ranged from 92° to 140° and 111° to 155° in the cases with and without metacarpophalangeal joint involvement, respectively

Many intensive care unit (ICU) patients describe pain and other adverse feelings that may impact long-term psychological morbidity. Sympathetically mediated palmar skin conductance variability is related to emotionally induced perspiration and correlates with pain levels in the perioperative setting but has not been studied in ICU patients. Twenty non-intubated and 20 intubated general ICU patients were included in this observational study. Patients were monitored with the MED-STORM Pain Monitoring System®. The number of skin conductance fluctuations per second (NSCF) was measured in parallel with bedside observation during one hour of intensive care, including rest, procedures and patient-staff interactions. Arousal-agitation level was monitored with the motor activity assessment scale (MAAS). Pain was monitored with the numeric rating scale (0 to 10) in patients able to communicate or by observation in patients unable to communicate. In non-intubated patients, NSCF increased with increasing stimulation/pain but also with higher MAAS (P=0.002). An interaction effect was found, with increased NSCF response to stimulation/pain with increasing MAAS (P<0.001). In critically ill patients, NSCF may be more useful evaluating emotional distress rather than pain alone. It needs to be assessed whether NSCF monitoring is clinically useful and whether controlling emotional distress with the aid of such monitoring may impact on patient care and outcomes.

To determine if pain of the dorsal margin of the sole in horses can be attenuated by anesthesia of either the distal interphalangeal (DIP) joint or the palmar digital (PD) nerves. A unilateral forelimb lameness was induced by creating solar pain. Response to administration of local anesthetic or saline solution into the DIP joint and to administration of local anesthetic around the PD nerves was evaluated. Six horses. Lameness was induced by creating pressure on the dorsal margin of the sole by screwing set-screws into a nut welded to the inside of each branch of a shoe. Gaits were evaluated before and after application of set-screws and after a local anesthetic or saline solution was administered into the DIP joint and, in a second trial, after a local anesthetic was injected around the PD nerves. Gaits recorded on videotape were evaluated, and lameness scores were assigned to each gait. Lameness scores were high after application of set-screws and remained high after saline solution was administered into the DIP joint. Scores decreased significantly (P < or = .05) after a local anesthetic was administered into the DIP joint or around the PD nerves. Analgesia of the DIP joint or the PD nerves desensitizes at least a portion of the sole. Pain arising from the sole should not be excluded as a cause of lameness when lameness is attenuated by analgesia of the DIP joint or PD nerves.

In order to undertake a fresh and detailed study of this muscle and to thus better understand human comparative anatomy and evolution, we: 1) analyze the frequency of the PPI in a large sample of human hands; 2) describe the attachments, innervation and varieties of the PPI in these hands; 3) compare the data obtained with the information available in the literature; and 4) discuss the phylogenetic origin of the PPI and the implications of our observations and comparisons for medicine and for the understanding of human evolutionary history. Within the 72 hands dissected by us, the PPI is present in 67 hands (93%), commonly having a single muscular branch, originating from the medial side of the base of metacarpal I only, inserting onto the medial side of the base of the pollical proximal phalanx and/or surrounding structures (e.g., ulnar sesamoid bone, wing tendon of extensor apparatus), and passing at least partially, and usually mainly, medial to the princeps pollicis artery. A careful study of the human PPI, as well as a detailed comparison with other mammals, strongly suggest that the muscle is evolutionarily derived from the adductor pollicis, and namely from its oblique head. Therefore, we propose that PPI should be designated by the name musculus adductor pollicis accessorius, which indicates that the muscle is most likely a de novo structure derived from the adductor pollicis.

Traditional endoscopic thoracic sympathicotomy is usually performed through an axillary incision with 5-mm thoracoscope under general anesthesia with endotrachea intubation. Nonintubated transareolar single-port thoracic sympathicotomy with a needle scope has rarely been attempted. The objective of this study is to evaluate the feasibility and safety of this minimally invasive technique in managing primary palmar hyperhidrosis (PPH). From May 2012 to May 2014, a total of 85 male patients with severe PPH underwent transareolar single-port thoracic sympathicotomy by use of a 2-mm needle scope under total intravenous anesthesia without endotrachea intubation. All procedures were successfully performed with a mean operating time of 13.5 min. The palms of all patients became dry and warm as soon as the sympathetic chain was cut off. There were no sore throat, and all the patients regained consciousness rapidly after surgery. Eighty-two patients (96.5 %) were discharged from the hospital on the first postoperative day. The postoperative complications were minor, and no patients developed Horner's syndrome. At 6 months postoperatively, there is no obvious surgical scar on the chest wall, and none of the patients complained about postoperative pain. Compensatory sweating appeared in 31 patients. No recurrent symptoms were observed in our study. One-year follow-up revealed an excellent cosmetic result and degree of satisfaction. Nonintubated transareolar single-port needlescopic thoracic sympathicotomy is a safe, effective and minimally invasive therapeutic procedure, which can be performed in routine clinical practice for male PPH patients.

A personal overview of causalgia and other reflex dystrophies.

This is a personal assessment of true major causalgia and the other reflex dystrophies, related but distinctly separate entities. The clinical picture of causalgia differs only in minor respects from that described by Mitchell over 120 years ago. Its management has, however, been clarified, largely through the extensive experiences of World War II. It is readily recognized and can be treated effectively by sympathetic blocks or sympathectomy together with active exercise. The other reflex dystrophies are far less understood. They appear to have a similar pattern in their early phase and to respond well to a program of exercise and control of edema--a regimen which, because of pain and paresis, cannot be carried out without sympathetic blocks or occasionally sympathectomy. When not recognized early and treated properly, the sympatomatology usually changes dramatically and treatment differs. Often control of edema and active use of the affected part are all that is necessary. Sometimes, in addition to these measures, sympathetic blocks or sympathectomy is required. Guidelines found useful in management are outlined. Puzzling features are discussed. PMID:3977427

Palmar skin conductance variability and the relation to stimulation, pain and the motor activity assessment scale in intensive care unit patients

PubMed Central

2013-01-01

Introduction Many intensive care unit (ICU) patients describe pain and other adverse feelings that may impact long-term psychological morbidity. Sympathetically mediated palmar skin conductance variability is related to emotionally induced perspiration and correlates with pain levels in the perioperative setting but has not been studied in ICU patients. Methods Twenty non-intubated and 20 intubated general ICU patients were included in this observational study. Patients were monitored with the MED-STORM Pain Monitoring System®. The number of skin conductance fluctuations per second (NSCF) was measured in parallel with bedside observation during one hour of intensive care, including rest, procedures and patient-staff interactions. Arousal-agitation level was monitored with the motor activity assessment scale (MAAS). Pain was monitored with the numeric rating scale (0 to 10) in patients able to communicate or by observation in patients unable to communicate. Results In non-intubated patients, NSCF increased with increasing stimulation/pain but also with higher MAAS (P = 0.002). An interaction effect was found, with increased NSCF response to stimulation/pain with increasing MAAS (P < 0.001). In intubated patients, NSCF increased significantly with increasing stimulation/pain (P < 0.001). In contrast to non-intubated patients, no difference in NSCF between MAAS levels was found for any given degree of stimulation in intubated patients. Conclusions In critically ill patients, NSCF may be more useful evaluating emotional distress rather than pain alone. It needs to be assessed whether NSCF monitoring is clinically useful and whether controlling emotional distress with the aid of such monitoring may impact on patient care and outcomes. PMID:23510014

Biofeedback, cognitive-behavioral methods, and hypnosis in dermatology: is it all in your mind?

Biofeedback can improve cutaneous problems that have an autonomic nervous system component. Examples include biofeedback of galvanic skin resistance (GSR) for hyperhidrosis and biofeedback of skin temperature for Raynaud's disease. Hypnosis may enhance the effects obtained by biofeedback. Cognitive-behavioral methods may resolve dysfunctional thought patterns (cognitive) or actions (behavioral) that damage the skin or interfere with dermatologic therapy. Responsive diseases include acne excoriée, atopic dermatitis, factitious cheilitis, hyperhidrosis, lichen simplex chronicus, needle phobia, neurodermatitis, onychotillomania, prurigo nodularis, trichotillomania, and urticaria. Hypnosis can facilitate aversive therapy and enhance desensitization and other cognitive-behavioral methods. Hypnosis may improve or resolve numerous dermatoses. Examples include acne excoriée, alopecia areata, atopic dermatitis, congenital ichthyosiform erythroderma, dyshidrotic dermatitis, erythromelalgia, furuncles, glossodynia, herpes simplex, hyperhidrosis, ichthyosis vulgaris, lichen planus, neurodermatitis, nummular dermatitis, postherpetic neuralgia, pruritus, psoriasis, rosacea, trichotillomania, urticaria, verruca vulgaris, and vitiligo. Hypnosis can also reduce the anxiety and pain associated with dermatologic procedures.

We retrospectively evaluated the safety and efficacy of computed tomography-guided placement of percutaneous catheters in close proximity to the thoracic sympathetic chain by rating pain intensity and systematically reviewing charts and computed tomography scans. Interventions were performed 322 times in 293 patients of mean (SD) age 59.4 (17.0) years, and male to female ratio 105:188, with postherpetic neuralgia (n = 103, 35.1%), various neuralgias (n = 88, 30.0%), complex regional pain syndrome (n = 69, 23.6%), facial pain (n = 17, 5.8%), ischaemic limb pain (n = 7, 2.4%), phantom limb pain (n = 4, 1.4%), pain following cerebrovascular accident (n = 2, 0.7%), syringomyelia (n = 2, 0.7%) and palmar hyperhidrosis (n = 1, 0.3%). The interventions were associated with a total of 23 adverse events (7.1% of all procedures): catheter dislocation (n = 9, 2.8%); increase in pain intensity (n = 8, 2.5%); pneumothorax (n = 3, 0.9%); local infection (n = 2, 0.6%); and puncture of the spinal cord (n = 1, 0.3%). Continuous infusion of 10 ml.h(-1) ropivacaine 0.2% through the catheters decreased median (IQR [range]) pain scores from 8 (6-9 [2-10]) to 2 (1-3 [0-10]) (p < 0.0001). Chemical neuroablation was necessary in 137 patients (46.8%). We conclude that this procedure leads to a significant reduction of pain intensity in otherwise obstinate burning or stabbing pain and is associated with few hazards. © 2011 The Authors.

Adrenergic factors involved in the control of crypt cell proliferation in jejunum and descending colon of mouse.

PubMed

Kennedy, M F; Tutton, P J; Barkla, D H

1983-01-01

The mitotic rates in the crypts of Lieberkühn of the proximal jejunum and descending colon of mouse, following different treatments, were measured using a stathmokinetic technique. Regression coefficients, representing mitotic rates, were then calculated by the method of least squares. Treatment with adrenaline, isoprenaline, phenylephrine, phentolamine, and yohimbine all resulted in decreased mitotic rate of jejunal and colonic crypt cells. Chemical sympathectomy and cryosympathectomy had a similar effect, and chemical sympathectomy was followed by a supersensitivity to clonidine. Intraperitoneal injection of metaraminol, clonidine, propranolol, prazosin, labetolol and simultaneous injection of propranolol and adrenaline all resulted in an increased rate of crypt cell proliferation in both jejunum and colon. A significant increase in mitotic rate was observed in both tissues at night. The amplitude of this diurnal variation was decreased in both jejunum and colon following chemical sympathectomy. In addition, the amplitude of this variation in jejunum was decreased after treatment with yohimbine or phentolamine. The results of the study suggest that the sympathetic nervous system stimulates epithelial cell proliferation in both the small and large intestine and that this effect is mediated by an alpha 2-adrenoceptor. By contrast, stimulation of alpha 1- and beta-adrenoceptors is inhibitory to cell proliferation in these tissues.

Direct and indirect effects of ephedrine on heart rate and blood pressure in vehicle-treated and sympathectomised male rats.

Alsufyani, Hadeel A; Docherty, James R

We have investigated the cardiac and pressor responses to (±)-ephedrine and (-)-ephedrine in pentobarbitone anaesthetized male wistar rats. The tachycardiac responses to (±)- and (-)-ephedrine were similar, but pressor responses to (-)-ephedrine (10 mg/kg) were significantly greater than those to (±)-ephedrine, and for both, the pressor response was followed by a small depressor response. Sympathectomy did not affect pressor responses, but significantly increased the later depressor response to both compounds. Sympathectomy did not affect tachycardiac or depressor responses to the β-adrenoceptor agonist isoprenaline, but significantly reduced the tachycardia to (±)-ephedrine. (±)-Ephedrine contracted vas deferens from vehicle treatment animals, but in vas deferens from sympathectomised rats, (±)-ephedrine produced almost no tonic contraction (α 1A -adrenoceptor mediated), but the phasic contraction was unaffected (α 1D -adrenoceptor mediated). It is concluded, firstly, that (-)-ephedrine is more potent than the racemate mixture at producing pressor responses. Secondly, since the depressor response to isoprenaline was unaffected, sympathectomy presumably reduced a pressor component to the response to (±)- and (-)-ephedrine. Hence, a component of the pressor response to both (±)- and (-)-ephedrine is indirect and may involve actions at α 1A -adrenoceptors, at which ephedrine does not have marked direct actions.

Effects of chemical sympathectomy on the increases in plasma catecholamines and dopamine-beta-hydroxylase induced by forced immobilization and insulin-induced hypoglycemia: origin and fate of plasma dopamine-beta-hydroxylase.

Israel, A S; Barbella, Y R; Cubeddu, L X

1982-06-01

The effect of acute stresses on plasma norepinephrine, epinephrine and dopamine-beta-hydroxylase (DBH) were evaluated in control and 6-hydroxydopamine-treated, awake cannulated guinea pigs. Forced immobolization for 1 hr caused a 3- and 5-fold increase in plasma DBH and norepinephrine, respectively. Pretreatment with 6-hydroxydopamine (23 mg/kg b.wt.i.a., 72 and 48 hr before stress) reduced by 70% the increase in plasma DBH and totally prevented the rise in plasma catecholamines evoked by the restraining stress. Injection of insulin (5 U/kg b.wt.i.a.) induced a 60% decrease in blood glucose, a 1-fold increase in plasma DBH and a selective 4-fold increase in plasma epinephrine; these effects were not modified by chemical sympathectomy. Our results indicate that forced immobilization and hypoglycemia produce a preferential activation of the sympathetic postganglionic nerves and of the adrenal medulla, respectively, and that in guinea pigs both stresses increase plasma DBH. The kinetics of disappearance of plasma DBH were studied after subjecting the guinea pigs for 1 hr to forced immobilization. Although 7 of 12 animals showed a biphasic rate of fall of plasma DBH, in each case there was a rapid initial fall possibly due to the "distribution" of the enzyme with a T1/2 of 1.65 hr. Similar findings were observed in 6-hydroxydopamine-treated guinea pigs. These results suggest that the distribution of DBH is the most important process in reducing the augmented plasma DBH levels elicited by a short-term stress and that this process is not dependent on the integrity of the sympathetic nerves nor on the adrenal or sympathetic origin of the enzyme. This study supports the view that the ratio, content of releasable DBH present in sympathetic nerves and adrenal glands/total circulating pool of DBH, is the factor that determines whether an increase in plasma DBH would occur in animals exposed to an acute stress.

Fracture heuristics: surgical decision for approaches to distal radius fractures. A surgeon's perspective.

PubMed

Wichlas, Florian; Tsitsilonis, Serafim; Kopf, Sebastian; Krapohl, Björn Dirk; Manegold, Sebastian

2017-01-01

Introduction: The aim of the present study is to develop a heuristic that could replace the surgeon's analysis for the decision on the operative approach of distal radius fractures based on simple fracture characteristics. Patients and methods: Five hundred distal radius fractures operated between 2011 and 2014 were analyzed for the surgeon's decision on the approach used. The 500 distal radius fractures were treated with open reduction and internal fixation through palmar, dorsal, and dorsopalmar approaches with 2.4 mm locking plates or underwent percutaneous fixation. The parameters that should replace the surgeon's analysis were the fractured palmar cortex, and the frontal and the sagittal split of the articular surface of the distal radius. Results: The palmar approach was used for 422 (84.4%) fractures, the dorsal approach for 39 (7.8%), and the combined dorsopalmar approach for 30 (6.0%). Nine (1.8%) fractures were treated percutaneously. The correlation between the fractured palmar cortex and the used palmar approach was moderate (r=0.464; p<0.0001). The correlation between the frontal split and the dorsal approach, including the dorsopalmar approach, was strong (r=0.715; p<0.0001). The sagittal split had only a weak correlation for the dorsal and dorsopalmar approach (r=0.300; p<0.0001). Discussion: The study shows that the surgical decision on the preferred approach is dictated through two simple factors, even in the case of complex fractures. Conclusion: When the palmar cortex is displaced in distal radius fractures, a palmar approach should be used. When there is a displaced frontal split of the articular surface, a dorsal approach should be used. When both are present, a dorsopalmar approach should be used. These two simple parameters could replace the surgeon's analysis for the surgical approach.

Thoracoscopic sympathectomy is now used routinely to treat patients with disabling primary hyperhidrosis or facial blushing. Published results are excellent, but side effects, such as compensatory sweating, are also very frequent. The surgical techniques used and the levels of targeting the sympathetic chain vary tremendously. Most surgeons transect or resect the sympathetic chain, but application of a metal clip that blocks transmission of nerve impulses in the sympathetic chain is used increasingly worldwide. This approach offers potential reversibility if patients regret surgery, but the question of reversibility remains controversial. Two recent experimental studies found severe histological signs of nerve damage 4-6 weeks after clip removal, but they only used conventional histopathological staining methods. Thoracoscopic clipping of the sympathetic trunk was performed in adult sheep, and the clip was removed thoracoscopically after 7 days. Following another 4 weeks (n = 6) or 12 weeks (n = 3), the sympathetic trunks were harvested and analysed by conventional and specific nerve tissue immunohistochemical stains (S100, neurofilament protein and synaptophysin). The contralateral sympathetic chains were used as controls. Conventional and immunohistochemical stains demonstrated severe signs of neural damage on the operated side 4 weeks after clip removal. After 12 weeks, these changes had decreased markedly and conventional histology had almost normalized. Conventional and immunohistochemical stains confirmed that application of metal clips to the sympathetic chain caused severe histological damage in the sympathetic trunk that remained visible 4 weeks after clip removal. However, after 12 weeks, these signs of damage had clearly decreased, which suggests in theory that application of metal clips to the sympathetic chain is a reversible procedure if only the observation period is prolonged. Further studies with longer periods between application and removal as

Dorsal dimelia in patau syndrome: a case report.

We present a case of a child with Patau syndrome that exhibits features consistent with congenital palmar nail syndrome. The literature is reviewed and evidence presented to demonstrate that this is a defect in the dorso-ventral patterning of the limb and thus a form of dorsal dimelia. In order to differentiate this from other instances of ectopic nail tissue we suggest congenital palmar nail syndrome should be more specifically defined as duplicated nails, absent flexion creases, non-glabrous skin on the palmar surface, reduced movement at the interphalangeal joints and hypoplastic terminal phalanges.

Mini open carpal tunnel release using Knifelight: evaluation of the safety and effectiveness of using a single wrist incision (cadaveric study).

This cadaveric study evaluates the margin of safety and technical efficacy of mini open carpal tunnel release performed using Knifelight (Stryker Instruments) through a transverse 1 cm wrist incision. A single investigator released 32 wrists in 17 cadavers. The wrists were then explored to assess the completeness of release and damage to vital structures including the superficial palmar arch, palmar cutaneous branch and recurrent branch of the median nerve. All the releases were complete and no injury to the median nerve and other structures were observed. The mean distance of the recurrent motor branch to the ligamentous divisions was 5.7 +/- 2.4 mm, superficial palmar arch was 8.7 +/- 3.1 mm and palmar cutaneous branch to the ligamentous division was 7.2 +/- 2.4 mm. The mean length of the transverse carpal ligament was 29.3 +/- 3.7 mm. Guyon's canal was preserved in all cases.

Differential control of collagen synthesis by the sympathetic and renin-angiotensin systems in the rat left ventricle.

In the present study, we tested the hypothesis of the indirect (via the sympathetic nervous system (SNS)) and direct (via AT1 receptors) contributions of Angiotensin II (Ang II) on the synthesis of collagen types I and III in the left ventricle (LV) in vivo. Sympathectomy and blockade of the Ang II receptor AT1 were performed alone or in combination in normotensive rats. The mRNA and protein synthesis of collagen types I and III were examined by Q-RT-PCR and immunoblotting in the LV. Collagen types I and III mRNA were decreased respectively by 53% and 22% after sympathectomy and only collagen type I mRNA was increased by 52% after AT1 receptor blockade. mRNA was not changed for collagen type I but was decreased by 25% for collagen type III after double treatment. Only collagen protein type III was decreased after sympathectomy by 12%, but collagen proteins were increased respectively for types I and III by 145% and 52% after AT1 receptor blockade and by 45% and 60% after double treatment. Deducted interpretations from our experimental approach suggest that Ang II stimulates indirectly (via SNS) and inhibits directly (via AT1 receptors) the collagen type I at transcriptional and protein levels. For collagen type III, it stimulates indirectly the transcription and inhibited directly the protein level. Therefore, the Ang II regulates collagen synthesis differently through indirect and direct pathways.

Variations in the nerves of the thumb and index finger.

Wallace, W A; Coupland, R E

1975-11-01

The digital nerves to the thumb and index finger have been studied by dissecting twenty-five embalmed upper limbs. The palmar digital nerves to the thumb were constant in position and course, with a short lateral cutaneous branch from the radial palmar digital nerve in 30 per cent of cases. The palmar digital nerves to the index finger had a variable pattern, the commonest arrangement, well described in Gray's Anatomy, occurring in 74 per cent of cases. The variations and their frequency are described. By examining histological cross-sections of the index finger it was found that of about 5,000 endoneurial tubes entering the finger, 60 per cent passed beyond the distal digital crease to supply the pulp and nail bed. The depth of the palmar digital nerves was about 3 millimetres, but less at the digital creases, and their diameter lay between 1 and 1.5 millimetres as far as the distal digital crease. Clinical applications of the findings are discussed.

Forty patients suffering from pustulosis palmoplantaris were treated with PUVA therapy. Thirty-six patients had palmar lesions which cleared in 31 cases; in 18 cases after an initial course of 3 sessions of treatment per week during an average period of 10 weeks, and in another 13 only after additional, less frequent continuation of the PUVA therapy. The average total UVA dose at clearing of the palmar lesions was 191 and the final UVA dose 7.3 J/cm2. After 2 years, 9 out of the 31 cases of palmar lesions were still completely healed, and the average duration of remission was greater than or equal to 15 months. For plantar lesions the results of PUVA therapy, using essentially the same procedure, were less satisfactory: healing being obtained in only 5 out of 34 cases. However, for palmar and plantar lesions alike, most patients have reported long-standing improvement from PUVA therapy. A surprisingly high frequency of nausea was noted as a side-effect.

Hand eczema is a common inflammatory dermatosis that causes significant patient morbidity. Previous studies comparing psoralen-ultraviolet A (PUVA) with narrowband ultraviolet B (NB-UVB) have been small, nonrandomized and retrospective. To conduct an observer-blinded randomized controlled pilot study using validated scoring criteria to compare immersion PUVA with NB-UVB for the treatment of chronic hand eczema unresponsive to topical steroids. Sixty patients with hand eczema unresponsive to clobetasol propionate 0·05% were randomized to receive either immersion PUVA or NB-UVB twice weekly for 12 weeks with assessments at intervals of 4 weeks. The primary outcome measure was the proportion of patients achieving 'clear' or 'almost clear' Physician's Global Assessment (PGA) response at 12 weeks. Secondary outcome measures included assessment of the modified Total Lesion and Symptom Score (mTLSS) and the Dermatology Life Quality index (DLQI). In both treatment arms, 23 patients completed the 12-week assessment for the primary outcome measure. In the PUVA group, five patients achieved 'clear' and eight 'almost clear' [intention-to-treat (ITT) response rate 43%]. In the NB-UVB group, two achieved 'clear' and five 'almost clear' (ITT response rate 23%). For the secondary outcomes, median mTLSS scores were similar between groups at baseline (PUVA 9·5, NB-UVB 9) and at 12 weeks (PUVA 3, NB-UVB 4). Changes in DLQI were similar, with improvements in both groups. In this randomized pilot trial recruitment was challenging. After randomization, there were acceptable levels of compliance and safety in each treatment schedule, but lower levels of retention. Using validated scoring systems - PGA, mTLSS and DLQI - as measures of treatment response, the trial demonstrated that both PUVA and NB-UVB reduced the severity of chronic palmar hand eczema. © 2017 British Association of Dermatologists.

Arterial supply of the thumb: Systemic review.

Miletin, J; Sukop, A; Baca, V; Kachlik, D

2017-10-01

We offer a complete systemic review of the anatomy of arteries of the thumb, including their sources in the first web space. Eleven studies were selected from the PubMed, Medline, Embase, Scopus and Ovid databases. Data about each artery of the thumb were obtained; in particular, the incidence and dominance of each of these arteries were calculated. The ulnopalmar digital artery of the thumb (UPDAT) was found in 99.63%, the radiopalmar digital artery of the thumb (RPDAT) in 99.26%, the ulnodorsal digital artery of the thumb (UDDAT) in 83.39%, and the radiodorsal digital artery of the thumb (RDDAT) in 70.38%. The sources for the thumb arteries are the first palmar metacarpal artery (for UPDAT in 63.15%, for RPDAT in 78.88%, for UDDAT in 56.95% and for RDDAT in 41.48%), the first dorsal metacarpal artery (for UPDAT in 20.54%, for RPDAT 2.53%, for UDDAT in 20.62%, and for RDDAT in 4.81%) and the superficial palmar arch, either complete or incomplete (for UPDAT in 25.57%, for RPDAT in 23.04%, for UDDAT in 0%, and for RDDAT in 5.19%). The dominant source could be identified in 88.2% of cases: the first palmar metacarpal artery (66.2%), the first dorsal metacarpal artery (15.5%) and the superficial palmar arch, complete or incomplete (8.2%). Four arteries usually supply the thumb. Any artery in the first web space can be a source for the thumb arteries. We propose a new classification of the arteries of the hand, dividing them into three systems (superficial palmar, deep palmar and dorsal system), and suggest that the term "princeps pollicis artery" be reconsidered and systemic anatomical terms of the thumb arteries preferred.

2015-01-01

Laser treatment is a widespread method for hair removal. Despite its very common use, side effects remain relatively rare and transient. Axillary hyperhidrosis and bromhidrosis have already been reported in the literature after depilatory lasers. We report here a novel side effect of total body bromhidrosis following hair removal laser. A 27-year-old man, phototype 3 underwent four sessions of total body depilatory laser, combining pulsed alexandrite and pulsed diode lasers. A few days afterwards, a generalized foul odor was noted and was resistant to regular deodorants and Aluminum chloride based antiperspirants. Possible mechanisms include the activation of dormant bacteria in the skin flora, sweat gland dysfunction, altered skin flora, sweat gland hormone receptor disturbances, and genetic factors. Total body bromhidrosis and hyperhidrosis are potential complications of total body laser hair removal.

2009-10-05

In the present study, we tested the hypothesis that angiotensin II (Ang II) has both direct (via AT1 receptors) and indirect (via sympathostimulator pathway) actions on the synthesis and activity of the enzymes involved in the extracellular matrix degradation in vivo. For this purpose, sympathectomy and blockade of the Ang II receptor AT1 were performed alone or in combination in normotensive rats. The mRNA of the plasminogen activator (t-PA) and its inhibitor (PAI-1), the mRNA, protein and activity of the matrix metalloproteinases MMP-2 and MMP-9 were examined by Q-RT-PCR, immunoblotting and zymographic methods in the left ventricle. t-PA and PAI-1 mRNA were decreased after sympathectomy and remained unchanged after AT1 receptors blockade. mRNA was increased for t-PA and decreased by similar degree for PAI-1 after double treatment. MMPs mRNA and protein levels were decreased either after sympathectomy or AT1 receptors blockade and an additive effect was acquired after double treatment. MMPs activity was decreased by similar degree in the three treated groups. Deducted interpretations from our experimental approach suggest that Ang II inhibits directly (via AT1 receptors) and indirectly (via sympathostimulator pathway) t-PA mRNA synthesis. It seems unable to influence directly PAI-1 mRNA, but stimulates indirectly PAI-1 mRNA synthesis. Ang II stimulates directly (via AT1 receptors) and indirectly (via sympathostimulator pathway) MMPs synthesis at both transcriptional and protein levels. The enzymatic activity of MMPs does not seem to be influenced directly by Ang II but it could be stimulated indirectly (via sympathostimulator pathway).

Currently available polyaxial locking plates represent the consequent enhancement of fixed-angle, first-generation locking plates. In contrast to fixed-angle locking plates which are sufficiently investigated, the strength of the new polyaxial locking options has not yet been evaluated biomechanically. This study investigates the mechanical strength of single polyaxial interfaces of different volar radius plates. Single screw-plate interfaces of the implants Palmar 2.7 (Königsee Implantate und Instrumente zur Osteosynthese GmbH, Allendorf, Germany), VariAx (Stryker Leibinger GmbH & Co. KG, Freiburg, Germany) und Viper (Integra LifeSciences Corporation, Plainsboro, NJ, USA) were tested by cantilever bending. The strength of 0 degrees, 10 degrees and 20 degrees screw locking angle was obtained during static and dynamic loading. The Palmar 2.7 interfaces showed greater ultimate strength and fatigue strength than the interfaces of the other implants. The strength of the VariAx interfaces was about 60% of Palmar 2.7 in both, static and dynamic loading. No dynamic testing was applied to the Viper plate because of its low ultimate strength. By static loading, an increase in screw locking angle caused a reduction of strength for the Palmar 2.7 and Viper locking interfaces. No influence was observed for the VariAx locking interfaces. During dynamic loading; angulation had no influence on the locking strength of Palmar 2.7. However, reduction of locking strength with increasing screw angulation was observed for VariAx. The strength of the polyaxial locking interfaces differs remarkably between the examined implants. Depending on the implant an increase of the screw locking angle causes a reduction of ultimate or fatigue strength, but not in all cases a significant impact was observed.

This study explored the immediate effects of Tai Chi (TC) training on attention and meditation, perceived stress level, heart rate, oxygen saturation level in blood, and palmar skin temperature in late middle-aged adults. Twenty TC practitioners and 20 nonpractitioners volunteered to join the study. After baseline measurements were taken, the TC group performed TC for 10 minutes while their cognitive states and cardiovascular responses were concurrently monitored. The control group rested for the same duration in a standing position. Both groups were then reassessed. The participants' attention and meditation levels were measured using electroencephalography; stress levels were measured using Perceived Stress Scale; heart rate and blood oxygenation were measured using an oximeter; and palmar skin temperature was measured using an infrared thermometer. Attention level tended to increase during TC and dropped immediately thereafter ( p < 0.001). Perceived stress level decreased from baseline to posttest in exclusively the TC group ( p = 0.005). Heart rate increased during TC ( p < 0.001) and decreased thereafter ( p = 0.001). No significant group, time, or group-by-time interaction effects were found in the meditation level, palmar skin temperature, and blood oxygenation outcomes. While a 10-minute TC training could temporarily improve attention and decrease perceived stress levels, it could not improve meditation, palmar skin temperature, or blood oxygenation among late middle-aged adults.

To investigate three-dimensional kinematics of the superficial and deep portion of triangular fibrocartilage complex (TFCC) in different parts of the forearm rotation. Six wrists of 6 volunteers were used to obtain CT scans at different positions of the wrist. The wrists were scanned from 90 degrees of pronation to 90 degrees of supination at an interval of 30 degrees. The 3-dimensional radius and ulna were reconstructed with customized software and changes in length of the superficial and deep portion of TFCC during forearm rotation. In forearm pronation, the superficial dorsal portion and the deep palmar portion of the TFCC were tight. While the superficial palmar portion and the deep dorsal potion of the TFCC were lax. In supination, the changes in length of all these fibers were reverse. In forearm rotation one portion fibers of dorsal TFCC and one portion fibers of palmar TFCC are tight, and this mechanism controls stability during DRUJ rotation.

The perceived distance between touches on the limbs is generally bigger for distances oriented across the width of the limb than for distances oriented along the length of the limb. The present study aimed to investigate the coherence of such distortions of tactile size perception across different skin surfaces. We investigated distortions of tactile size perception on the dorsal and palmar surfaces of both the left and right hands as well as the forehead. Participants judged which of two tactile distances felt larger. One distance was aligned with the proximodistal axis (along the body), the other with the mediolateral axis (across the body). Clear distortions were found on all five skin surfaces, with stimuli oriented across the width of the body being perceived as farther apart than those oriented along the length of the body. Consistent with previous results, distortions were smaller on the palmar than on the dorsal hand surface. Distortion on the forehead was intermediate between the dorsal and palmar surfaces. There were clear correlations between distortion on the left and right hands, for both the dorsal and palmar skin surfaces. In contrast, within each hand, there was no significant correlation between the two skin surfaces. Distortion on the forehead was not significantly correlated with that on any of the other skin surfaces. These results provide evidence for bilaterally symmetric representations underlying tactile size perception. © The Author(s) 2015.

The aim of our present study is to investigate the interaction between angiotensin II (ANG II) and sympathetic nervous system (SNS) on matrix metalloproteinase MMP-2 and MMP-9 expression and activity in juvenile rat aorta under normal conditions. Sympathectomy with guanethidine and blockade of the ANG II receptors (AT1R) by losartan were performed alone or in combination on new-born rats. mRNA, protein expression and activity of MMP-2 and MMP-9 were examined by Q-RT-PCR, immunoblotting and zymography, respectively. MMP-2 mRNA and protein amount were decreased after sympathectomy or AT1R blockade and an additive effect was observed after combined treatment. However, MMP-9 expression was reduced to the same level in the three treated groups. There were some detectable gelatinolytic activity of the MMPs in both control and treated rats. We concluded that ANG II stimulates directly and indirectly (via sympathostimulator pathway) the MMP-2 expression but seems unable to affect MMP-9 expression through direct pathway. Combined inhibition of SNS and ANG II were more efficient than a single inhibition in reducing MMP amounts in rat vessels.

Polyaxial angle-stable plating is thought to be particularly beneficial in the management of complex intra-articular fractures of the distal radius. The present study was performed to investigate the strength of polyaxial locking interfaces of distal radius plates. We tested the polyaxial interfaces of 3 different distal radius plates (2.4 mm Variable Angle LCP Two-Column Volar Distal Radius Plate, Synthes, Palmar Classic, Königsee Implantate and VariAx Plate Stryker). The strength of 0° and 10° screw locking angle was obtained during static loading. The strength of Palmar Classic with a 0° locking angle is significantly the best of all tested systems. With a 10° locking angle there is no significant difference between Palmar Classic, Two column Plate and VariAx Plate. The strength of polyaxial interfaces differs between the tested systems. A reduction of ultimate strength is due to increases of screw locking angle. The design of polyaxial locking interfaces should be investigated in human bone models. © Georg Thieme Verlag KG Stuttgart · New York.

To identify demographic, injury-related, or psychologic factors associated with finger stiffness at suture removal and 6 weeks after distal radius fracture surgery. We hypothesize that there are no factors associated with distance to palmar crease at suture removal. Prospective cohort study. Level I Academic Urban Trauma Center. One hundred sixteen adult patients underwent open reduction and internal fixation of their distal radius fractures; 96 of whom were also available 6 weeks after surgery. None. At suture removal, we recorded patients' demographics, AO fracture type, carpal tunnel release at the time of surgery, pain catastrophizing scale, Whiteley Index, Patient Health Questionnaire-9, and disabilities of the arm, shoulder, and hand questionnaire, 11-point ordinal measure of pain intensity, distance to palmar crease, and active flexion of the thumb through the small finger. At 6 weeks after surgery, we measured motion, disabilities of the arm, shoulder, and hand, and pain intensity. Prereduction and postsurgery radiographic fracture characteristics were assessed. Female sex, being married, specific surgeons, carpal tunnel release, AO type C fractures, and greater catastrophic thinking were associated with increased distance to palmar crease at suture removal. At 6 weeks, greater catastrophic thinking was the only factor associated with increased distance to palmar crease. Catastrophic thinking was a consistent and major determinant of finger stiffness at suture removal and 6 weeks after injury. Future research should assess if treatments that ameliorate catastrophic thinking can facilitate recovery of finger motion after operative treatment of a distal radius fracture. Prognostic Level I.

2011-05-01

Eccrine angiomatous hamartoma is a rare, benign tumor characterized by a proliferation of eccrine and vascular structures. We present 2 cases and review the characteristics of this disorder. The first patient was a 33-year-old woman who consulted for a brownish lesion on her back associated with local hyperhidrosis. The second patient was a 25-year-old man with an asymptomatic erythematous lesion on his left palm. In both patients a diagnosis of eccrine angiomatous hamartoma was made based on the histological findings. Eccrine angiomatous hamartoma is usually present at birth or develops during childhood. It is typically a solitary lesion and signs and symptoms can vary; diagnosis is therefore based on histological study. The most common site is on the distal parts of limbs. The lesions tend to be asymptomatic, but there may be associated pain and hyperhidrosis. Treatment is not usually necessary except in cases with persistent symptoms, excessive sweating, or cosmetic concerns. Copyright © 2010 Elsevier España, S.L. y AEDV. All rights reserved.

A 54-year-old woman presented with a large mass on her right hand that was progressively enlarging over a period of a few years. She had cosmetic concerns about the enlarging mass and experienced interference with routine activity. Physical examination revealed a soft, mobile, non-tender, lobulated mass with well-defined margins. Magnetic resonance imaging showed the soft lump to be a lipomatous mass in the deep palmar space of the hand, which was subsequently surgically resected. The imaging features of deep palmar lipomas of the hand and other common benign lesions at this location are discussed. Copyright: © Singapore Medical Association.

Alteration of corneal epithelial ion transport by sympathectomy.

Klyce, S D; Beuerman, R W; Crosson, C E

1985-04-01

The cornea is dually innervated, receiving afferent nerves from the trigeminal ganglion and efferent nerves from the superior cervical ganglion. This study examines the specific effects of superior cervical ganglionectomy (SCGX) on the in vitro ion transport characteristics of the rabbit corneal epithelium. Two weeks after SCGX, epithelial Cl--dependent transport and total ionic conductance were increased in comparison to values obtained in paired control eyes. This increased transport level appeared to be independent of membrane receptor activity as demonstrated by lack of responsiveness to alpha-adrenergic, beta-adrenergic, serotonergic, dopaminergic, nicotinic cholinergic, or muscarinic cholinergic blockade. Nevertheless, SCGX produced a supersensitivity to epinephrine-stimulated transport as measured by the responsiveness of the ion transport current. Furthermore, SCGX abolished the responsiveness of the epithelium to serotonin. On the basis of these and earlier findings, the authors conclude that corneal sympathetic innervation influences membrane and receptor properties. Autonomic neurotrophic effects in the corneal epithelium include suppression of apical membrane Cl- permeability and of beta-adrenoreceptor sensitivity to biogenic amines. It is proposed that the corneal serotonergic receptors that activate Cl- transport lie on the sympathetic nerve terminals and stimulate this transport process by causing the neural release of a catecholamine.

Severe ischemic pain is difficult to treat with a single therapy. Although modern angiogenic therapies have been used in patients with peripheral arterial occlusive diseases, a regimen combining novel angiogenic therapy and classic nerve blocks, including sympathectomy, has not been discussed to date. In this case report, we present two patients with peripheral arterial occlusive disease who were first treated with medication and lumbar sympathectomy, and then with a novel gelatin hydrogel drug-delivery system loaded with basic fibroblast growth factor. The gelatin hydrogel combined with recombinant basic fibroblast growth factor was injected intramuscularly into the ischemic limbs. In the first patient, with arteriosclerosis obliterans, a foot ulcer was healed, and the original score for resting pain (visual analogue scale, 5/10) was decreased to 0/10. In the second patient, with Buerger's disease, a large toe ulcer was healed, and his resting pain (visual analogue scale, 8/10) was decreased to 1/10. Some other parameters, such as skin surface temperature, transcutaneous oxygen partial pressure, and pain-free walking distance, were also improved in both patients after the combined therapy. A multimodal approach is necessary to treat severe ischemic pain. Novel angiogenic therapy combined with nerve blocks seems to be a promising option in patients with severe pain.

The deep lymphatic anatomy of the hand still remains the least described in medical literature. Eight hands were harvested from four nonembalmed human cadavers amputated above the wrist. A small amount of 6% hydrogen peroxide was employed to detect the lymphatic vessels around the superficial and deep palmar vascular arches, in webs from the index to little fingers, the thenar and hypothenar areas. A 30-gauge needle was inserted into the vessels and injected with a barium sulphate compound. Each specimen was dissected, photographed and radiographed to demonstrate deep lymphatic distribution of the hand. Five groups of deep collecting lymph vessels were found in the hand: superficial palmar arch lymph vessel (SPALV); deep palmar arch lymph vessel (DPALV); thenar lymph vessel (TLV); hypothenar lymph vessel (HTLV); deep finger web lymph vessel (DFWLV). Each group of vessels drained in different directions first, then all turned and ran towards the wrist in different layers. The deep lymphatic drainage of the hand has been presented. The results will provide an anatomical basis for clinical management, educational reference and scientific research. Copyright © 2018 Elsevier GmbH. All rights reserved.

Development of emotional sweating in the newborn infant.

Sweating from the palm and sole occurs independently of ambient temperature but is influenced by emotional factors. It thus provides a useful objective measure of emotional state. The development of this emotional sweating in the newborn was investigated by measuring palmar water loss and relating it to the infant's state of arousal. Although 433 individual measurements were made on 124 babies of gestational age 25 to 41 weeks and postnatal age 15 hours to 9 weeks. Palmar water loss was also recorded continuously in 22 infants undergoing heel prick for routine blood sampling. In babies of 37 weeks' gestation or more, there was a clear relationship between palmar water loss and arousal from the day of birth, and by the third week levels on vigorous crying were comparable with those of an anxious adult. Less mature babies did not show emotional sweating at birth; it was first seen at the equivalent of 36 to 37 weeks' gestation regardless of maturity. Continuous recordings confirmed the cross-sectional data and illustrated the abrupt nature of the response. Emotional sweating could be a useful tool for the assessment of emotional state of the newborn.

One of the most common psychiatric diagnoses among adolescents is anxiety disorder. Many of the anxiety symptoms are expressed physiologically, and therefore can mimic other medical conditions. The aim of this study was to examine the association between anxiety disorders and other medical conditions sharing common symptoms with anxiety (MDSCSA: Irritable Bowel Syndrome, asthma, migraine and hyperhidrosis). The study was based on the national database of the candidates for military service in Israel. Data for the years 1998-2013 was retrieved to create the study dataset. The final cohort population was comprised of 1,229,461 military service candidates. Anxiety prevalence and its association with other medical conditions sharing the same symptoms was examined in the cohort. The results showed significant statistical association between anxiety and IBS, asthma, migraine and hyperhidrosis. These findings support the fact that there is a clear association between anxiety disorder and the examined medical conditions. Moreover, in the military setting, the primary care physician has an important role in giving a correct diagnosis for soldiers presenting with symptoms that can be regarded both to anxiety and to other physical illnesses.

Quantitative Fluctuating (FA) and Directional asymmetry (DA) of dermatoglyphics on digito-palmar complex were analyzed in a group of 111 patients (males: 61, females: 50) with schizophrenia (SZ), and compared to an ethnically matched phenotypically healthy control (males: 60, females: 60) through MANOVA, ANOVA and canonical Discriminant analyses. With few exceptions, asymmetries are higher among patients, and this is more prominent in FA than DA. Statistically significant differences were observed between patient and control groups, especially in males. In both sexes, FA of combined dermatoglyphic traits (e.g. total finger ridge count, total palmar pattern ridge count) are found to be a strong discriminator between the two groups with a correct classification of over 83% probability.

2016-01-01

Background: The management of contractures and soft tissue defects in the proximal interphalangeal (PIP) finger joint remains a challenge. We report a transposition flap from the lateral skin of the proximal phalanx that is based on perforating branches of the digital arteries and can be used safely for both palmar and dorsal cover defects. Methods: We first completed an anatomic study, dissecting 20 fingers in fresh cadavers with arterial injections and made the new flap in patients with dorsal or palmar defects in PIP joints. Results: In cadavers, we can reveal 4 constant branches from each digital artery in the proximal phalanx, with the more distal just in the PIP joint constituting the flap pedicle. Between February 2010 and February 2015, we designed 33 flaps in 29 patients, 7 for dorsal and 26 for palmar defects, with no instances of flap necrosis and 4 distal epidermolysis. The patients were between 4 and 69 years with no major complications, and all of the skin defects in the PIP joint were resolved satisfactorily without any relevant sequelae at the donor site. Conclusions: This flap procedure is an easy, reliable, versatile, and safe technique, and could be an important tool for the management of difficult skin defects and contractures at the PIP joint level.

In the rehabilitation field, the use of additive manufacturing techniques to realize customized orthoses is increasingly widespread. Obtaining a 3D model for the 3D printing phase can be done following different methodologies. We consider the creation of personalized upper limb orthoses, also including fingers, starting from the acquisition of the hand geometry through accurate 3D scanning. However, hand scanning procedure presents differences between healthy subjects and patients affected by pathologies that compromise upper limb functionality. In this work, we present the concept and design of a 3D printed support to assist hand scanning of such patients. The device, realized with FDM additive manufacturing techniques in ABS material, allows palmar acquisitions, and its design and test are motivated by the following needs: (1) immobilizing the hand of patients during the palmar scanning to reduce involuntary movements affecting the scanning quality and (2) keeping hands open and in a correct position, especially to contrast the high degree of hypertonicity of spastic subjects. The resulting device can be used indifferently for the right and the left hand; it is provided in four-dimensional sizes and may be also suitable as a palmar support for the acquisition of the dorsal side of the hand.

Dupuytren’s disease (palmar fibromatosis) involves nodules in fascia of the hand that leads to flexion contractures. Ledderhose disease (plantar fibromatosis) is similar with nodules of the foot. While clinical aspects are well-described, genetic mechanisms are unknown. We report a family with cardiac disease due to a heterozygous LMNA mutation (c.736C>T, p.Gln246Stop) with palmar/plantar fibromatosis and investigate the hypothesis that a second rare DNA variant increases the risk for fibrotic disease in LMNA mutation carriers. The proband and six family members were evaluated for the cardiac and hand/feet phenotypes and tested for the LMNA mutation. Fibroblast RNA studies revealed monoallelic expression of the normal LMNA allele and reduced lamin A/C mRNAs consistent with LMNA haploinsufficiency. A novel, heterozygous missense variant (c.230T>C, p.Val77Ala) in the Asteroid Homolog 1 (ASTE1) gene was identified as a potential risk factor in fibrotic disease using exome sequencing and family studies of five family members: four LMNA mutation carriers with fibromatosis and one individual without the LMNA mutation and no fibromatosis. With a possible role in epidermal growth factor receptor signaling, ASTE1 may contribute to the increased risk for palmar/plantar fibromatosis in patients with Lamin A/C haploinsufficiency.

Prof. Dr. René Leriche was a famous French surgeon who lived between 1879 and 1955. After working as a vascular surgeon in Lyon, he was appointed professor at the University of Strasbourg in 1924 and later the Paris Collége de France in 1937. Leriche had proposed vascular patches as the ideal treatment for obliterated vascular segments and advocated the necessity of sympathectomy in arterial diseases in the 1920s. He defined “Leriche Syndrome” in 1923 which is known by his name and which develops as a result of incomplete obstruction of the aortic bifurcation. René Leriche wrote a monograph entitled “La Chirurgie de la Douleur-Pain Surgery” in 1940 and he also became a pioneer in the sympathectomy procedure for pain treatment. René Leriche focused on topics that must be remembered again today, including surgery advanced into science, the physiological basis of surgery, research methods, as well as issues such as business technology, humanity in surgery, surgical essence and surgeon’s qualifications in the book entitled “La Philosophie de la Chirurgie-Philosophy of Surgery” that he wrote in 1951. In this review, the issues that Prof. Dr. René Leriche addressed in middle of the 20th century were revised in the light of contemporary medical ethics. PMID:25931863

The long-term results of a technique for correction of syndactyly are reported. The technique consists of a dorsal omega flap and a palmar anchor forming two palmar and lateral flaps. A long-term review was made of 50 patients with a minimum of 8 years follow-up operated over a period of 10 years. A total of 122 web spaces in simple, complex and syndromic syndactyly were operated on. Most patients achieved satisfactory reconstruction of the web spaces, resulting in a web of good shape. At long-term review, web creep was recorded in eight webs, and skin contractures in three fingers. This study shows the technique to be effective in reconstructing web spaces and in minimizing the prevalence of complications.

Odonto-onycho-dermal dysplasia (OODD) is a rare form of ectodermal dysplasia characterized by severe oligodontia, onychodysplasia, palmoplantar hyperkeratosis, dry skin, hypotrichosis, and hyperhidrosis of the palms and soles. The ectodermal dysplasias resulting from biallelic mutations in the WNT10A gene result in highly variable phenotypes, ranging from isolated tooth agenesis to OODD and Schöpf-Schulz-Passarge syndrome (SSPS). We identified a female patient, with consanguineous parents, who was clinically diagnosed with OODD. Genetic testing showed that she was homozygous for a previously reported pathogenic mutation in the WNT10A gene, c.321C > A, p.Cys107*. The skin and nail abnormalities were for many years interpreted as psoriasis and treated accordingly. A thorough clinical examination revealed hypotrichosis and hyperhidrosis of the soles and dental examination revealed agenesis of permanent teeth except the two maxillary central incisors. Skin biopsies from the hyperkeratotic palms and soles showed the characteristic changes of eccrine syringofibroadenomatosis, which has been described in patients with ectodermal dysplasias. Together with a family history of tooth anomalies, this lead to the clinical suspicion of a hereditary ectodermal dysplasia. This case illustrates the challenges of diagnosing ectodermal dysplasia like OODD and highlights the relevance of interdisciplinary cooperation in the diagnosis of rare conditions.

The aim was to compare digital and palmar dermatoglyphics in subjects with dementia of Alzheimer type and in mentally healthy elderly controls. This design was a case-control study. The study was carried out in geriatric units and retirement communities in the Paris area. Cases were women with clinically diagnosed Alzheimer type dementia according to DSM III-R criteria (n = 82), mainly with late onset of the disease. Controls were women aged 85 years or older without cognitive deterioration (n = 76). Finger and palm prints obtained from both hands by the classical ink method were examined. Fingerprints were classified into four types of figures. On palms, palmar flexion creases, palmar axial triradii, true patterns of the hypothenar area, and main line terminations were described. Examinations were performed by two examiners blind to the subjects's diagnostic category. For the different patterns studied, no major differences between dementia patients and elderly controls were found. Nor was there evidence of high frequencies of features commonly observed in Down's syndrome (trisomy 21), which have previously, though sporadically, been reported. On one of the largest samples of Alzheimer dementia patients studied, and with evaluation blind to diagnosis, no evidence has been found that particular dermatoglyphic patterns occur like those observed in Down's syndrome, a disease which is related to dementia of the Alzheimer type.

Granulosis Rubra Nasi (GRN) is a rare disorder of the eccrine glands. It is clinically characterized by hyperhidrosis of the central part of the face, most commonly on the tip of the nose, followed by appearance of diffuse erythema over the nose, cheeks, chin, and upper lip. It is commonly seen in childhood but it can present in adults. Here we report a case of GRN in an adult patient with very unusual histopathological presentation.

Dupuytren's contracture (DC) is a fibroproliferative disorder of unknown etiology characterized by a scar-like contracture that develops in the palm and/or digits. We have previously reported that the eta subunit of the chaperonin containing T-complex polypeptide (CCT-eta) is increased in fibrotic wound healing, and is essential for the accumulation of α-smooth muscle actin (α-SMA) in fibroblasts. The purpose of this study was to determine if CCT-eta is similarly implicated in the aberrant fibrosis seen in DC and to investigate the role of CCT-eta in the behavior of myo/fibroblasts in DC. Fibroblasts were obtained from DC-affected palmar fascia, from adjacent phenotypically normal palmar fascia in the same DC patients (PF), and from non-DC palmar fascial tissues in patients undergoing carpal tunnel (CT) release. Inherent contractility in these three populations was examined using fibroblast-populated collagen lattices (FPCLs) and by cell traction force microscopy. Expression of CCT-eta and α-SMA protein was determined by Western blot. The effect of CCT-eta inhibition on the contractility of DC cells was determined by deploying an siRNA versus CCT-eta. DC cells were significantly more contractile than both matching palmar fascial (PF) cells and CT cells in both assays, with PF cells demonstrating an intermediate contractility in the FPCL assay. Whereas α-SMA protein was significantly increased only in DC cells compared to PF and CT cells, CCT-eta protein was significantly increased in both PF and DC cells compared to CT cells. siRNA-mediated depletion of CCT-eta inhibited the accumulation of both CCT-eta and α-SMA protein in DC cells, and also significantly decreased the contractility of treated DC cells. These observations suggest that increased expression of CCT-eta appears to be a marker for latent and active disease in these patients and to be essential for the increased contractility exhibited by these fibroblasts.

Independent development of the Reach and the Grasp in spontaneous self-touching by human infants in the first 6 months.

The Dual Visuomotor Channel Theory proposes that visually guided reaching is a composite of two movements, a Reach that advances the hand to contact the target and a Grasp that shapes the digits for target purchase. The theory is supported by biometric analyses of adult reaching, evolutionary contrasts, and differential developmental patterns for the Reach and the Grasp in visually guided reaching in human infants. The present ethological study asked whether there is evidence for a dissociated development for the Reach and the Grasp in nonvisual hand use in very early infancy. The study documents a rich array of spontaneous self-touching behavior in infants during the first 6 months of life and subjected the Reach movements to an analysis in relation to body target, contact type, and Grasp. Video recordings were made of resting alert infants biweekly from birth to 6 months. In younger infants, self-touching targets included the head and trunk. As infants aged, targets became more caudal and included the hips, then legs, and eventually the feet. In younger infants hand contact was mainly made with the dorsum of the hand, but as infants aged, contacts included palmar contacts and eventually grasp and manipulation contacts with the body and clothes. The relative incidence of caudal contacts and palmar contacts increased concurrently and were significantly correlated throughout the period of study. Developmental increases in self-grasping contacts occurred a few weeks after the increase in caudal and palmar contacts. The behavioral and temporal pattern of these spontaneous self-touching movements suggest that the Reach, in which the hand extends to make a palmar self-contact, and the Grasp, in which the digits close and make manipulatory movements, have partially independent developmental profiles. The results additionally suggest that self-touching behavior is an important developmental phase that allows the coordination of the Reach and the Grasp prior to and

To evaluate clinical aspects, results and the economic impact of the outpatient thoracic surgery programme (OTSP) developed in our Department. Prospective study of 300 patients who entered in the OTSP from April 2001 to March 2005. The procedures performed were video-mediastinoscopy (MC), video-thoracoscopic lung biopsy (LB) and video-thoracoscopic bilateral thoracic sympathectomy (TS). All procedures were performed under general anaesthesia and patients were discharged in 4-6h. We analyse demographic data, the substitution index (SI), the admission rate (AR) and readmission rate (RR) after the procedure. We calculate the economic impact of stay expenses on our hospital and on other Spanish hospitals. The female/male ratio of the 300 patients was 83/217, with a mean age of 58.1 years (range: 15-85 years). There were no deaths. Mediastinoscopy was performed as outpatient procedure in 210 patients (mean age: 65.6 years) out of 244 total MC (SI=86.1%). Two patients were admitted (AR=0.95%) to observe a minimal pneumothorax and because of late night end. There were no readmissions after MC (RR=0%). We included 32 ambulatory patients for lung biopsy (mean age: 61.5 years) out of 64 total LB (SI=50.0%). One patient was admitted because of air leak (AR=3.1%) and there were no readmissions after LB (RR=0%). Fifty-eight patients were included in the OTSP for bilateral sympathectomy (mean age: 27.1 years) out of 83 total TS (SI=69.9%); there were no admissions (AR=0%) and one patient was readmitted after 9 days because of a hemothorax (RR=1.7%). Sixty-four patients out of the 91 not included in the OTSP were included in an 'afternoon surgical programme' and dismissed the morning after surgery, without contraindication for their inclusion in the OTSP. The hospital's total stay saving was 12,668 euros (88,226 euros if performed elsewhere), 42 euros per patient (294 euros per patient if performed elsewhere).

A 43-year-old woman with a 3-year history of headache, fever, and swelling of the forehead, presented to our hospital. A general examination revealed palmar and plantar pustules. Blood analyses showed an elevated white blood cell count, C-reactive protein level, and erythrocyte sedimentation rate. Brain MRI revealed a partially thickened cranial bone with gadolinium enhancement, and also abnormally enhanced dura mater. Bone scintigraphy showed involvement of the cranial bone and bilateral sternoclavicular joints. Palmar skin biopsy indicated palmoplantar pustulosis. From these results, SAPHO (synovitis, acne, pustulosis, hyperostosis and osteitis) syndrome with associated hypertrophic pachymeningitis was diagnosed. After corticosteroid therapy and tonsillectomy, the clinical symptoms and radiological abnormalities were improved. Clinicians should be aware of SAPHO as a potential unusual cause of hypertrophic pachymeningitis. Copyright © 2014 Elsevier B.V. All rights reserved.

Direct and indirect cardiovascular actions of cathinone and MDMA in the anaesthetized rat.

PubMed

Alsufyani, Hadeel A; Docherty, James R

2015-07-05

The stimulants cathinone (from Khat leaves) and methylenedioxymeth-amphetamine (MDMA) produce adrenoceptor mediated tachycardia and vasopressor actions that may be the result of direct receptor stimulation, actions on the noradrenaline transporter, and/or displacement of noradrenaline from nerve terminals. Effects of cathinone or MDMA were compared with those of the indirect sympathomimetic tyramine. Male Wistar rats were anaesthetized with pentobarbitone for blood pressure and heart rate recording. Some rats were sympathectomised by treatment with 6-hydroxydopamine. In the anaesthetised rat, cathinone, MDMA and tyramine (all 0.001-1 mg/kg) produced marked tachycardia, tyramine produced marked pressor responses and MDMA produced small pressor responses. The tachycardia to cathinone and MDMA was almost abolished by propranolol (1mg/kg). Pretreatment with cocaine (1mg/kg) did not significantly affect the tachycardia to cathinone or MDMA, but reduced the response to tyramine. However, in sympathectomised rats, the tachycardia to cathinone or MDMA was markedly attenuated, but the tachycardia to tyramine was only partially reduced. Blood pressure effects of tyramine and MDMA were also markedly attenuated by sympathectomy. The results demonstrate firstly that cocaine may not be the most suitable agent for assessing direct versus indirect agonism in cardiovascular studies. Secondly, the use of chemical sympathectomy achieved the desired goal of demonstrating that cardiac β-adrenoceptor mediated actions of cathinone and MDMA are probably largely indirect.

Extracellular matrix (ECM) synthesis regulation by sympathetic nervous system (SNS) or angiotensin II (ANG II) was widely reported, but interaction between the two systems on ECM synthesis needs further investigation. We tested implication of SNS and ANG II on ECM synthesis in juvenile rat aorta. Sympathectomy with guanethidine (50 mg/kg, subcutaneous) and blockade of the ANG II AT1 receptors (AT1R) blocker with losartan (20 mg/kg/day in drinking water) were performed alone or in combination in rats. mRNA and protein synthesis of collagen and elastin were examined by Q-RT-PCR and immunoblotting. Collagen type I and III mRNA were increased respectively by 62 and 43% after sympathectomy and decreased respectively by 31 and 60% after AT1R blockade. Combined treatment increased collagen type III by 36% but not collagen type I. The same tendency of collagen expression was observed at mRNA and protein levels after the three treatments. mRNA and protein level of elastin was decreased respectively by 63 and 39% and increased by 158 and 15% after losartan treatment. Combined treatment abrogates changes induced by single treatments. The two systems act as antagonists on ECM expression in the aorta and combined inhibition of the two systems prevents imbalance of mRNA and protein level of collagen I and elastin induced by single treatment. Combined inhibition of the two systems prevents deposit or excessive reduction of ECM and can more prevent cardiovascular disorders.

Barreto Junior, Elton Pereira de Sá; Nascimento, Jedson Dos Santos; de Castro, Anita Perpetua Carvalho Rocha

Sympathectomy is one of the therapies used in the treatment of chronic obstructive arterial disease (COAD). Although not considered as first-line strategy, it should be considered in the management of pain difficult to control. This clinical case describes the evolution of a patient with inoperable COAD who responded properly to the lumbar sympathetic block. A female patient, afro-descendant, 69 years old, ASA II, admitted to the algology service due to refractory ischemic pain in the lower limbs. The patient had undergone several surgical procedures and conservative treatments without success. Vascular surgery considered the case as out of therapeutic possibility, unless limb amputation. At that time, sympathectomy was indicated. After admission to the operating room, the patient was monitored, positioned and sedated. The blockade was performed with the aid of radioscopy, bilaterally, at L2-L3-L4 right and L3 left levels. On the right side, at each level cited, 3mL of absolute alcohol with 0.25% bupivacaine were injected without vasoconstrictor, and on the left side only local anesthetic. The procedure was performed uneventfully. The patient was discharged with complete remission of the pain. Neurolitic block of the lumbar sympathetic chain is an effective and safe treatment option for pain control in patients with critical limb ischemia patients in whom the only possible intervention would be limb amputation.

Circadian variations in cell proliferation in normal tissues have been recognised for many years but comparable phenomena in neoplastic tissues appear not to have been reported. Adenomas and carcinomas were induced in mouse colon by injection of dimethylhydrazine (DMH) and cell proliferation in these tumors was measured stathmokinetically. In normal intestine cell proliferation is fastest at night whereas in both adenomas and carcinomas it was found to be slower at night than in the middle of the day. Chemical sympathectomy was found to abolish the circadian variation in tumor cell proliferation.

This study compared the efficacy between external fixator combined with palmar T-plate internal fixation and simple plate internal fixation for the treatment of comminuted distal radius fractures. A total of 61 patients classified as type C according to the AO/ASIF classification underwent surgery for comminuted distal radius fractures. There were 54 and 7 cases of closed and open fractures, respectively. Moreover, 19 patients received an external fixator combined with T-plate internal fixation, and 42 received simple plate internal fixation. All patients were treated successfully during 12-month postoperative follow-up. The follow-up results show that the palmar flexion and dorsiflexion of the wrist, radial height, and palmar angle were significantly better in those treated with the external fixator combined with T-plate compared to those treated with the simple plate only (P < 0.05); however, there were no significant differences in radial-ulnar deviation, wrist range of motion, or wrist function score between groups (P > 0.05). Hence, the effectiveness of external fixator combined with T-plate internal fixation for the treatment of comminuted distal radius fractures was satisfactory. Patients sufficiently recovered wrist, forearm, and hand function. In conclusion, compared to the simple T-plate, the external fixator combined with T-plate internal fixation can reduce the possibility of the postoperative re-shifting of broken bones and keep the distraction of fractures to maintain radial height and prevent radial shortening.

Geometric symmetry of the solar surface of hooves of thoroughbred racehorses.

To define a 3-dimensional (3-D) coordinate system with clear definitions of origins and axes relative to hoof anatomic features and determine whether solar surfaces of Thoroughbred racehorse hooves have geometric asymmetry in the mediolateral and dorsopalmar directions. Left forelimb hooves from 20 Thoroughbred racehorse cadavers. A right-handed 3-D coordinate axes system centered on the collateral sulci was defined for the left front hoof. Orthogonal distances of anatomic features from the dorsopalmar axis and the plane coincident with the ground were measured and compared between medial and lateral sides and between dorsal and palmar regions of the hoof. The hoof was wider and had a greater radius laterally than medially. The most distal part of the lateral bar of the frog was further from the dorsopalmar axis than that of the medial bar. Overall, mediolateral asymmetries in depth were not observed. The sole at the perimeter was deeper medially in the dorsal part of the hoof and laterally in the palmar part, with depth overall being greater palmarly than dorsally. Most features had dorsopalmar asymmetry. When the angle bisected by the collateral sulci is used to determine the dorsopalmar axis of the hoof, most central structures (bars and collateral sulci) have mediolateral symmetry. However, the hoof wall and sole have some mediolateral asymmetries and most structures have dorsopalmar asymmetry. These findings may assist the development of devices for attachment to hooves and studies of the interaction of hooves with bearing surfaces.

Osteitis--an under-recognised association with seronegative spondyloarthropathy?

PubMed

Stebbings, S; Highton, J; Doyle, T C; Jeffery, A K

1997-12-12

To emphasise osteitis as a feature of the spondyloarthritides. We describe four cases spanning a spectrum of the spondyloarthritides in which osteitis was a feature. One patient had psoriatic arthritis with palmar-plantar pustular psoriasis and extensive osteitis involving the tibia and fibula. This case provides a link with two cases with SAPHO syndrome (synovitis, acne, pustulosis hyperostosis, osteitis) who had palmar-plantar pustulosis and osteitis. Many now argue that this syndrome is a form of spondyloarthritis. The fourth case, which was of particular interest to us, had enteric reactive arthritis and scintigraphic changes strongly suggesting the presence of osteitis of individual bones in the wrist. We propose that these four cases demonstrate that osteitis may be another feature common to the spondyloarthritides and SAPHO. Awareness of this may facilitate better documentation of this feature of the disease.

Studies on topical antiperspirant control of axillary hyperhidrosis.

PubMed

Shelley, W B; Hurley, H J

1975-01-01

Axillary hyperhidrotics is reviewed from the standpoint of anatomical factors, physiological mechanisms and the history of methods of control. Anhydrous aluminum chloride and anhydrous zirconium tetrachloride are shown to be superior topical agents for partial control of axillary sweating when applied as a powder or in anhydrous nonreactive vehicles. Complete anhidrosis as demonstrated by sustained garment armpit dryness could be achieved in hyperhidrotics within 48 hours by the following trinary antiperspirant system: (1) a saturated solution of aluminum chloride hexahydrate or zirconyl chloride in absolute ethanol or isopropyl alcohol, (2) application to the dry axilla at times of sleep or other prolonged non-sweating period, (3) water vapor occlusion of area for 6 to 8 hours by means of Saran wrap. The hypothesis is presented that metallic antiperspirants act by reflux entrance into the terminal intraepidermal eccrine duct, slowly combining with the intraductal keratin, to produce a fibrillar contraction (super contraction) of keratin and hence functional closure, not histologically evident. This altered keratin is shed weeks later, with the consequent return of ductal patency and sweating.

Circadian rhythms of gastrointestinal function are regulated by both central and peripheral oscillators

Malloy, Jaclyn N.; Paulose, Jiffin K.; Li, Ye

2012-01-01

Circadian clocks are responsible for daily rhythms in a wide array of processes, including gastrointestinal (GI) function. These are vital for normal digestive rhythms and overall health. Previous studies demonstrated circadian clocks within the cells of GI tissue. The present study examines the roles played by the suprachiasmatic nuclei (SCN), master circadian pacemaker for overt circadian rhythms, and the sympathetic nervous system in regulation of circadian GI rhythms in the mouse Mus musculus. Surgical ablation of the SCN abolishes circadian locomotor, feeding, and stool output rhythms when animals are presented with food ad libitum, while restricted feeding reestablishes these rhythms temporarily. In intact mice, chemical sympathectomy with 6-hydroxydopamine has no effect on feeding and locomotor rhythmicity in light-dark cycles or constant darkness but attenuates stool weight and stool number rhythms. Again, however, restricted feeding reestablishes rhythms in locomotor activity, feeding, and stool output rhythms. Ex vivo, intestinal tissue from PER2::LUC transgenic mice expresses circadian rhythms of luciferase bioluminescence. Chemical sympathectomy has little effect on these rhythms, but timed administration of the β-adrenergic agonist isoproterenol causes a phase-dependent shift in PERIOD2 expression rhythms. Collectively, the data suggest that the SCN are required to maintain feeding, locomotor, and stool output rhythms during ad libitum conditions, acting at least in part through daily activation of sympathetic activity. Even so, this input is not necessary for entrainment to timed feeding, which may be the province of oscillators within the intestines themselves or other components of the GI system. PMID:22723262

This article was designed to consider the congenital age-specific features of palm dermatoglyphics in the adults subjects (including the type of the papillary patterns, axial tri-radii, the termini of palmar main lines, the rudiments of palmar lines, the dermatoglyphic ridge count between the stable anatomical structures). The objective of the study was to look for the new diagnostic markers of the biological age. It included the identification of the palm prints obtained from 180 Caucasoid men and 120 women at the age varying from 16 to 80 years. The results of the mathematical and statistical analysis provided the basis for drawing up the list of 18 attributes of palm dermatoglyphics significantly (p<0.05) differing in the frequency of occurrence between the representatives of individual age groups. The methods are proposed allowing to use these findings for the expert evaluation of the age of unknown subjects.

Infrared thermography based on artificial intelligence as a screening method for carpal tunnel syndrome diagnosis.

2009-01-01

This study further evaluated a computer-based infrared thermography (IRT) system, which employs artificial neural networks for the diagnosis of carpal tunnel syndrome (CTS) using a large database of 502 thermal images of the dorsal and palmar side of 132 healthy and 119 pathological hands. It confirmed the hypothesis that the dorsal side of the hand is of greater importance than the palmar side when diagnosing CTS thermographically. Using this method it was possible correctly to classify 72.2% of all hands (healthy and pathological) based on dorsal images and > 80% of hands when only severely affected and healthy hands were considered. Compared with the gold standard electromyographic diagnosis of CTS, IRT cannot be recommended as an adequate diagnostic tool when exact severity level diagnosis is required, however we conclude that IRT could be used as a screening tool for severe cases in populations with high ergonomic risk factors of CTS.

Functional classification of grasp strategies used by hemiplegic patients

Roby-Brami, Agnès; Robertson, Johanna; Roche, Nicolas

2017-01-01

This study aimed to identify and qualify grasp-types used by patients with stroke and determine the clinical parameters that could explain the use of each grasp. Thirty-eight patients with chronic stroke-related hemiparesis and a range of motor and functional capacities (17 females and 21 males, aged 25–78), and 10 healthy subjects were included. Four objects were used (tissue packet, teaspoon, bottle and tennis ball). Participants were instructed to “grasp the object as if you are going to use it”. Three trials were video-recorded for each object. A total of 456 grasps were analysed and rated using a custom-designed Functional Grasp Scale. Eight grasp-types were identified from the analysis: healthy subjects used Multi-pulpar, Pluri-digital, Lateral-pinch and Palmar grasps (Standard Grasps). Patients used the same grasps with in addition Digito-palmar, Raking, Ulnar and Interdigital grasps (Alternative Grasps). Only patients with a moderate or relatively good functional ability used Standard grasps. The correlation and regression analyses showed this was conditioned by sufficient finger and elbow extensor strength (Pluri-digital grasp); thumb extensor and wrist flexor strength (Lateral pinch) or in forearm supinator strength (Palmar grasp). By contrast, the patients who had severe impairment used Alternative grasps that did not involve the thumb. These strategies likely compensate specific impairments. Regression and correlation analyses suggested that weakness had a greater influence over grasp strategy than spasticity. This would imply that treatment should focus on improving hand strength and control although reducing spasticity may be useful in some cases. PMID:29125855

Although the role of the skin in the development and propagation of Dupuytren disease remains unclear, dermofasciectomy and full-thickness skin grafting (FTSG) appears to delay recurrence. In 2011, a 71-year-old, left-handed man presented with recurrent Dupuytren disease in the dominant hand. In 1991, he originally underwent a primary dermofasciectomy and FTSG for Dupuytren disease involving the palmar skin. Twenty years later, the left middle finger was drawn into flexion by a recurrent cord, and the old graft and adjacent palmar skin were clinically involved by fibromatosis. We performed a revision dermofasciectomy and FTSG. Microscopic analysis of the excised graft demonstrated dense infiltration of the entire skin graft by Dupuytren disease, with areas of active and burnt-out fibromatosis distinct from hypertrophic scarring. This report of Dupuytren fibromatosis infiltrating a skin graft raises questions about the pathophysiology of Dupuytren disease. Copyright © 2016 American Society for Surgery of the Hand.

[The artery of the thumb metacarpophalangeal joint].

PubMed

Schmidt, V H; Fischer, G

1994-07-01

As a rule, a small artery passing through the palmar plate runs into the thumb metacarpophalangeal joint. Frequently, the joint vessel arises from the arteria princeps pollicis, and rarely from the arteria metacarpalis dorsalis I or from muscle branches of the arteria princeps pollicis. In 30% of our specimens we could find a third larger palmar thumb artery. To our knowledge, this vessel was not described up to now precisely. Frequently arising from the arteria princeps pollicis, it passes the whole region of the metacarpophalangeal joint of the thumb. Distally, the artery runs within the floor of the flexor pollicis longus tendon sheath. After a mean distance of 19.7 mm, the vessel passes through the wall of the tendon sheath between the A 1-pulley and the oblique pulley. This vessel anastomoses with the arteria radiopalmaris pollicis proximal to the junction of the digitopalmar arch. According to the nomenclature of anatomic variations in the forearm, we suggest to name the additional thumb vessel "Arteria mediana pollicis".

Innervated boomerang flap for finger pulp reconstruction.

The boomerang flap originates from the dorsolateral aspect of the proximal phalanx of an adjacent digit and is supplied by the retrograde blood flow through the vascular arcades between the dorsal and palmar digital arteries. To provide sensation of the boomerang flap for finger pulp reconstruction, the dorsal sensory branch of the proper digital nerve and the superficial sensory branch of the corresponding radial or ulnar nerve are included within the skin flap. After transfer of the flap to the injured site, epineural neurorrhaphies are done between the digital nerves of the pulp and the sensory branches of the flap. We used this sensory flap in five patients, with more than 1 year follow-up, and all patients achieved measurable two-points discrimination. The boomerang flap not only preserves the proper palmar digital artery but also provides an extended and innervated skin paddle. It seems to be an alternative choice for one-stage reconstruction of major pulp defect.

This study describes a strong aponeurosis on the caudal surface of the antebrachium, between the Mm. Flexoris and the M. pronator quadratus. This aponeurosis has not been experimentally validated. By dissection and macroscopic examination of formaldehyde-prepared material, and experimental surgical transection of the structure in F. catus, the aponeurosis is described and its functional capacity is determined. The origin of the aponeurosis is the Facies caudalis, Margo medialis of the Radius and distal Ulna and inserts on the Crista transversa of the Radius and the Ligg. radiocarpeum palmare and ulno-carpeum palmare, and a strong Pars radialis. Its disposition is similar to that of the supernumerary M. anterior radialis brevis in humans. Surgical transection of the aponeurosis in F. catus resulted in hyperextension of the Manus and a decrease in the Carpus in its weight-bearing ability. These findings indicate the anatomico-functional importance of the aponeurosis in providing support to the claws.

Self-measurement of blood pressure (BP) might offer some advantages in diagnosis and therapeutic evaluation and in patient management of hypertension. Recently, wrist-cuff devices for self-measurement of BP have gained more than one-third of the world market share. In the present study, we validated wrist-cuff devices and compared the results between wrist- and arm-cuff devices. The factors affecting the accuracy of wrist-cuff devices were also studied. The research group to assess the validity of automated blood pressure measuring device consisted of 13 institutes in Japan, which validated two wrist-cuff devices (WC-1 and WC-2) and two arm-cuff devices (AC-1 and AC-2). They used a crossover method, where the comparison was done between auscultation, by two observers by means of a double stethoscope on one arm and the device on the opposite arm or wrist. There was good inter-observer agreement for the auscultation method in each institute (systolic blood pressure (SBP), -0.1 +/- 2.8 mmHg; diastolic blood pressure (DBP), -0.1 +/- 2.6 mmHg, n = 498). The mean difference between auscultation and the device was minimal both in arm-cuff devices (mean difference for AC-1, 2.2/1.9 mmHg, n = 97 and for AC-2, 5.1/2.9 mmHg, n = 136, SBP/DBP) and wrist-cuff devices (mean difference for WC-1, -2.1/1.2 mmHg, n = 173 mmHg and for WC-2, -2.3/-5.6 mmHg, n = 92). The standard deviation of the difference (SDD) in wrist-cuff devices, however (SDD for WC-1, 9.7/7.3 mmHg and for WC-2, 10.2/8.6 mmHg), was larger than that of the arm-cuff devices (SDD for AC-1, 5.6/6.6 mmHg and for AC-2, 6.3/5.1 mmHg). Grading of AC-1 and AC-2 based on criteria of British Hypertension Society was A/A and B/A, respectively, while that of WC-1 and WC-2 was C/B and D/B, respectively. Using the same validation protocol, the results of validation for one device were divergent in each institute. In wrist-cuff devices, the BP value obtained in palmar flexion was significantly higher and that obtained in palmar

Tinea cruris is an intensely pruritic fungal infection of the groin and adjacent skin. Also known as crotch rot and jock itch, it can be a troubling important entity that at times is a clinical, diagnostic, and therapeutic challenge. Predisposing factors include heat, humidity, and hyperhidrosis, common accompaniments of high school-aged athletes. Furthermore, obesity and diabetes mellitus, additional risk factors for tinea cruris, are reaching unprecedented levels in adolescents. Treatment options range from improving hygiene to topical antifungal agents and systemic antifungal agents, the latter with potentially dangerous side effects.

Changes in fetal heart rate variability (FHRV) and ST segment elevation (measured as the T/QRS ratio) are used to evaluate fetal adaptation to labour. The sympathetic nervous system (SNS) is an important contributor to FHRV under healthy normoxic conditions, and is critical for rapid support of blood pressure during brief labour-like asphyxia. However, although it has been assumed that SNS activity contributes to FHRV during labour; this has never been tested, and it is unclear whether the SNS contributes to the rapid increase in T/QRS ratio during brief asphyxia. Thirteen chronically instrumented fetal sheep at 0.85 of gestation received either chemical sympathectomy with 6-hydroxydopamine (6-OHDA; n = 6) or sham treatment (control; n = 7), followed 4-5 days later by 2 min episodes of complete umbilical cord occlusion repeated every 5 min for up to 4 h, or until mean arterial blood pressure fell to <20 mmHg for two successive occlusions. FHRV was decreased before occlusions in the 6-OHDA group (P < 0.05) and 2-4.5 h during recovery after occlusions (P < 0.05) compared to the control group. During each occlusion there was a rapid increase in T/QRS ratio. Between successive occlusions the T/QRS ratio rapidly returned to baseline, and FHRV increased above baseline in both groups (P < 0.05), with no significant effect of sympathectomy on FHRV or T/QRS ratio. In conclusion, these data show that SNS activity does not mediate the increase in FHRV between repeated episodes of brief umbilical cord occlusion or the transient increase in T/QRS ratio during occlusions. © 2015 The Authors.

Only a limited proportion of patients needing pharmacological control of portal hypertension are hemodynamic responders to propranolol. Here we analyzed the effects of zolmitriptan on portal pressure and its potential interaction with propranolol. ZOLMITRIPTAN, PROPRANOLOL OR BOTH WERE TESTED IN TWO RAT MODELS OF PORTAL HYPERTENSION: common bile duct ligation (CBDL) and CCl4-induced cirrhosis. In these animals we measured different hemodynamic parameters including portal venous pressure, arterial renal flow, portal blood flow and cardiac output. We also studied the changes in superior mesenteric artery perfusion pressure and in arterial wall cAMP levels induced by zolmitriptan, propranolol or both. Moreover, we determined the effect of splanchnic sympathectomy on the response of PVP to zolmitriptan. In both models of portal hypertension zolmitriptan induced a dose-dependent transient descent of portal pressure accompanied by reduction of portal flow with only slight decrease in renal flow. In cirrhotic rats, splanchnic sympathectomy intensified and prolonged zolmitriptan-induced portal pressure descent. Also, propranolol caused more intense and durable portal pressure fall when combined with zolmitriptan. Mesenteric artery perfusion pressure peaked for about 1 min upon zolmitriptan administration but showed no change with propranolol. However propranolol enhanced and prolonged the elevation in mesenteric artery perfusion pressure induced by zolmitriptan. In vitro studies showed that propranolol prevented the inhibitory effects of β2-agonists on zolmitriptan-induced vasoconstriction and the combination of propranolol and zolmitriptan significantly reduced the elevation of cAMP caused by β2-agonists. Zolmitriptan reduces portal hypertension and non-selective beta-blockers can improve this effect. Combination therapy deserves consideration for patients with portal hypertension failing to respond to non-selective beta-blockers.

Objective To compare the effect of two different hand exercises on hand strength and vascular maturation in patients who underwent arteriovenous fistula surgery. Methods We recruited 18 patients who had chronic kidney disease and had undergone arteriovenous fistula surgery for hemodialysis. After the surgery, 10 subjects performed hand-squeezing exercise with GD Grip, and other 8 subjects used Soft Ball. The subjects continued the exercises for 4 weeks. The hand grip strength, pinch strength (tip, palmar and lateral pinch), and forearm circumference of the subjects were assessed before and after the hand-squeezing exercise. The cephalic vein size, blood flow velocity and volume were also measured by ultrasonography in the operated limb. Results All of the 3 types of pinch strengths, grip strength, and forearm circumference were significantly increased in the group using GD Grip. Cephalic vein size and blood flow volume were also significantly increased. However, blood flow velocity showed no difference after the exercise. The group using Soft Ball showed a significant increase in the tip and lateral pinch strength and forearm circumference. The cephalic vein size and blood flow volume were also significantly increased. On comparing the effect of the two different hand exercises, hand-squeezing exercise with GD Grip had a significantly better effect on the tip and palmar pinch strength than hand-squeezing exercise with Soft Ball. The effect on cephalic vein size was not significantly different between the two groups. Conclusion The results showed that hand squeezing exercise with GD Grip was more effective in increasing the tip and palmar pinch strength compared to hand squeezing exercise with soft ball.

Background: Oral squamous cell carcinoma (SCC) is one name that causes panic and holds an undeserved high ranking as a killer. Another important condition which has become a major public health issue in South East Asia is oral submucous fibrosis (OSF). Not all the people using tobacco suffer from these diseases. Genetic predisposition might explain such an individual variability that can be predicted by using various cytogenetic markers. However, these studies are far more costly and complicated. So, dermatoglyphics may be of immense clinical significance to segregate those individuals who are at an increased risk for developing these diseases. Aim: The present study was conducted to analyze the palmar dermatoglyphics in SCC and OSF and find a dermatoglyphic marker, if any. Study Design: Cross sectional study. Materials and Methods: 120 individuals were divided into four groups based upon their habits of tobacco/areca nut usage and presence of OSF/SCC. Dermatoglyphic patterns were recorded using standard ink method. Various patterns were analysed statistically in the four groups. Results and Conclusion: In SCC, there was an increase in frequency of arch and ulnar loop patterns on fingertips, decrease in frequency of simple whorl patterns on fingertips, decrease in frequency of palmar accessory triradii on right and left hands. Significant findings in OSF included an increase in frequency of arch and ulnar loop pattern, decrease in frequency of simple whorl patterns on fingertips, decrease in atd angle on right hand, decrease in frequency of palmar accessory triradii on right hand. The results revealed that the field of dermatoglyphics holds promising results for determining the genetic susceptibility of individuals to develop SCC and OSF. PMID:24403787

Raynaud phenomenon may be a primary disorder or associated with a variety of other autoimmune processes. Raynaud phenomenon produces digital vasospasm, which can lead to ischemia and ulceration. The treatment of Raynaud phenomenon has been difficult because multiple medical treatments have not provided uniform resolution of symptoms. Many patients have turned to surgery and sympathectomies for the treatment of unrelenting vasospasm. Botulinum toxin has been shown to be an effective alternative to surgery, with a single treatment being capable of resolving pain and healing ulcer.

The present study evaluates the use of a laser guidance system for CT-guided intervention. 94 cases of diagnostic biopsies and lumbar sympathectomies (54 cases with laser guidance system and 40 without) were compared. Using the laser guidance system, the number of control scans decreased by 30 to 50%, and necessary corrections of needle location were reduced by a maximum of 30%. The average target deviation of the needle decreased to less than 5 mm in 50% of cases. The laser guidance system is strongly recommended in CT-guided interventions for quality assurance and higher efficiency. The advantage is especially marked if the target area is small.

To study the operative procedure and the effectiveness of arthroscopic therapy for ankle joint impingement syndrome after operation of ankle joint fracture dislocation. Between March 2008 and April 2010, 38 patients with ankle joint impingement syndrome after operation of ankle joint fracture dislocation were treated. Among them, there were 28 males and 10 females with an average age of 28 years (range, 18 to 42 years). The time from internal fixation to admission was 12-16 months (mean, 13.8 months). There were pressing pain in anterolateral and anterior ankle. The dorsal extension ranged from -20 to -5 degrees (mean, -10.6 degrees), and the palmar flexion was 30-40 degrees (mean, 35.5 degrees). The total score was 48.32 +/- 9.24 and the pain score was 7.26 +/- 1.22 before operation according to American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score system. The X-ray films showed osteophyte formation in anterior tibia and talus; MRI showed cartilage injury in 22 cases. Arthroscopic intervention included removing osteophytes, debriding fabric scars and synovial membrane tissues, and removing osteochondral fragments. Arthroscopic microfracture technique was used in 22 patients with cartilage injury. All incisions healed primarily. Thirty-eight cases were followed up 10-26 months (mean, 16 months). At last follow-up, 26 patients had normal range of motion (ROM); the dorsal extension was 15-25 degrees (mean, 19.6 degrees) and the palmar flexion was 35-45 degrees (mean, 40.7 degrees). Eight patients had mild limited ROM; the dorsal extension was 5-15 degrees (mean, 7.2 degrees) and the palmar flexion was 35-45 degrees (mean, 39.5 degrees). Four patients had mild limited ROM and pain in posterior portion of the ankle after a long walking (3-4 hours); the dorsal extension was 0-5 degrees (mean, 2.6 degrees) and the palmar flexion was 35-40 degrees (mean, 37.5 degrees).

Dupuytren's disease is a fibro-proliferative disorder affecting ~3-5% of the UK population. Current surgical treatments for Dupuytren's contracture (DC) include fasciectomy and fasciotomy. We assessed the clinical management of DC in England over a 5-year period; associated NHS costs were assessed for a 1-year period. Hospital Episode Statistics were extracted from April 2003 to March 2008 for patients with Palmar Fascial Fibromatosis (ICD10=M720) and DC-related procedures. Variables included demographics, OPCS, patient status and physician specialty. To estimate 2010-2011 costs, HRG4 codes and the National Schedule of Tariff 2010-11-NHS Trusts were applied to the 2007-2008 period. Over 5 years, 75,157 DC admissions were recorded; 64,506 were analyzed. Mean admissions per year were 12,901 and stable. Day cases increased from 42% (2003-2004) to 62% (2007-2008). The percent of patients having two or more admissions per year increased from 5.5% in 2003-2004 to 26.1% in 2007-2008. Between 2003 and 2007, 91% of procedures were Fasciectomy. Revision of Fasciectomy and Fasciotomy each accounted for ~4%; Amputation for 1%. In 2007, classification was extended to identify Digital Fasciectomy, its Revision and Dermofasciectomy. In 2007-2008, admissions were: 70% Palmar Fasciectomy, 16% Digital Fasciectomy, 1.3% Other Fasciectomy, 4.4% Revision of Palmar Fasciectomy, 1.3% Revision of Digital Fasciectomy, 3.8% Division of Palmar Fascia, 2.6% Dermofasciectomy and 1.1% Amputation. 79% of cases were overseen by trauma and orthopaedic surgeons, 19% by plastic surgeons. Mean (±SD) inpatient hospital length of stay was 1.5 (±1.4) days in 2003-2004 and 1.0 (±1.3) days in 2007-2008. Total estimated costs for 1 year (2010-2011) were £41,576,141. Per-patient costs were £2,885 (day case) and £3,534 (inpatient). Costs ranged from £2,736 (day-case Fasciectomy) to £9,210 (day-case Revision Digital). Between 2003 and 2008, fasciectomy was the most common surgical procedure for DC in

The length of hospital stay is an important factor of cost and psychological discomfort in the treatment of hyperhidrosis by endoscopic thoracic sympathicotomy (ETS). Our experience enrolls 1587 patients operated on an outpatient basis in the last 10 years and seven months. This study aimed to confirm that ETS can be performed on an outpatient basis. Fifty-two consecutive patients (30 males and 22 females) were submitted to ETS under general anesthesia using a single lumen endotracheal tube, with lung collapse by intrapleural injection of CO(2). The sympathetic chain and the communicating rami were severed at different levels according to hyperhidrosis location. Patients were physical state American Society of Anesthesiologists 1 and 2. Age varied between 13 and 55 years (27.3 +/- 10.2 years). They were monitored with ECG, SPO2, NIBP, expired CO(2), sevoflurane analyzer, and airway pressure. Normal saline (40.0 +/- 2.7 ml/kg) was infused intravenously. The drugs used were propofol, alfentanil, rocuronium, ondansetron, dexamethasone, dipyrone, cetoprofene and sevoflurane. Anesthesia and post-operative data were analyzed. Post-operative thoracic X-rays were taken in 20 patients before discharge. Anesthesia lasted 67.2 +/- 20.8 minutes, and the surgical procedure took 46.3 +/- 20.9 minutes. The patients stayed 18.0 +/- 11.0 minutes in the post-anaesthetic care unit and were discharged from hospital after 150.3 +/- 43.1 minutes. The only abnormal post-operative event observed was insignificant residual carbothorax, found in 2 (10%) of the thoracic X-rays taken. In conclusion, this study confirmed that ETS can be performed safely on an outpatient basis.

Neurofibromatosis type 1 (NF1) is frequently associated with neurological disorders unrelated to neurofibromas, including sleep disorders. This article reviews the prevalence of sleep disorders in patients with NF1, compares rates to data reported in the literature, and analyses the relationship between cognitive disorder and attention deficit hyperactivity disorder (ADHD) in these patients. Comparative retrospective study reviewing data collected between January 2010 and January 2012 from patients diagnosed with NF1 in a tertiary hospital. We included 95 paediatric patients with NF1 who completed the Bruni Sleep Disturbance Scale in Children. The overall prevalence of sleep disorders was 6.3%, which was lower than in the general paediatric population. Patients with NF1 and ADHD had a higher prevalence of sleep onset and maintenance disorders (18% vs 6.3%), sleep-wake transition disorders (12.5% vs 6.3%), and daytime sleepiness (12.5% vs 7.9%); differences were not statistically significant. A statistically significant difference was found in the subdomain of nocturnal hyperhidrosis (21.9% vs 6.3%, P < 0.05). Patients with NF1 and IQ<85 showed higher prevalence rates of daytime sleepiness (20% vs 6.7%) and of sleep hyperhidrosis (11% vs 0%). The prevalence of sleep disorders in our cohort of patients with NF1 was no higher than in the general paediatric population, although some of these disorders are more common in cases with cognitive disorders or ADHD.

The kinematic analysis of human grasping is challenging because of the high number of degrees of freedom involved. The use of principal component and factorial analyses is proposed in the present study to reduce the hand kinematics dimensionality in the analysis of posture for ergonomic purposes, allowing for a comprehensive study without losing accuracy while also enabling velocity and acceleration analyses to be performed. A laboratory study was designed to analyse the effect of weight and diameter in the grasping posture for cylinders. This study measured the hand posture from six subjects when transporting cylinders of different weights and diameters with precision and power grasps. The hand posture was measured using a Vicon(®) motion-tracking system, and the principal component analysis was applied to reduce the kinematics dimensionality. Different ANOVAs were performed on the reduced kinematic variables to check the effect of weight and diameter of the cylinders, as well as that of the subject. The results show that the original twenty-three degrees of freedom of the hand were reduced to five, which were identified as digit arching, closeness, palmar arching, finger adduction and thumb opposition. Both cylinder diameter and weight significantly affected the precision grasping posture: diameter affects closeness, palmar arching and opposition, while weight affects digit arching, palmar arching and closeness. The power-grasping posture was mainly affected by the cylinder diameter, through digit arching, closeness and opposition. The grasping posture was largely affected by the subject factor and this effect couldn't be attributed only to hand size. In conclusion, this kinematic reduction allowed identifying the effect of the diameter and weight of the cylinders in a comprehensive way, being diameter more important than weight.

Jesensek Papez, B; Palfy, M; Turk, Z

2008-01-01

Thermography for the measurement of surface temperatures is well known in industry, although is not established in medicine despite its safety, lack of pain and invasiveness, easy reproducibility, and low running costs. Promising results have been achieved in nerve entrapment syndromes, although thermography has never represented a real alternative to electromyography. Here an attempt is described to improve the diagnosis of carpal tunnel syndrome with thermography using a computer-based system employing artificial neural networks to analyse the images. Method reliability was tested on 112 images (depicting the dorsal and palmar sides of 26 healthy and 30 pathological hands), with the hand divided into 12 segments and compared relative to a reference. Palmar segments appeared to have no beneficial influence on classification outcome, whereas dorsal segments gave improved outcome with classification success rates near to or over 80%, and finger segments influenced by the median nerve appeared to be of greatest importance. These are preliminary results from a limited number of images and further research will be undertaken as our image database grows.

Effects of hypercapnia and hypoxia on nasal vasculature and airflow resistance in the anaesthetized dog.

PubMed Central

Lung, M A; Wang, J C

1986-01-01

The experiments were performed on anaesthetized dogs which breathed spontaneously or were artificially ventilated and paralysed. The spontaneous nasal arterial blood flow was measured on one side of the nose while nasal vascular resistance was determined on the other side simultaneously. Nasal arterial blood flow was measured by means of an electromagnetic flow sensor placed around the terminal branch of the internal maxillary artery, the main arterial supply to the nasal mucosa. Nasal vascular resistance was measured by constant-flow perfusion of the terminal branch of the internal maxillary artery. Nasal airway resistance was assessed by monitoring the transnasal pressure at constant airflow through each side of the nose simultaneously. Hypercapnic gas challenge (8% CO2, 30% O2 in N2) to the lungs increased nasal vascular resistance and decreased nasal airway resistance. Similar gas challenge to the nose did not affect nasal vascular resistance but decreased nasal airway resistance. Hypoxic gas challenge (6% O2 in N2) to the lungs did not affect the nasal vascular resistance but decreased nasal airway resistance only when the nasal vascular bed was under controlled perfusion. Similar gas challenge to the nose did not affect either nasal vascular or airway resistance. Arterial chemoreceptor stimulation by intracarotid injection of sodium cyanide increased nasal vascular resistance and decreased nasal airway resistance. The nasal vascular response to hypercapnia and arterial chemoreceptor stimulation was reflex in nature, being abolished by nasal sympathectomy. The nasal airway response to hypercapnia, hypoxia and arterial chemoreceptor stimulation was reflex in nature, being partially or completely abolished by nasal sympathectomy. Hypercapnia probably induced a local vasodilatatory effect on the capacitance vessels whereas hypoxia had no direct action on the vasculature. PMID:3091811

In vivo sweat film layer thickness measured with Fourier-domain optical coherence tomography (FD-OCT)

NASA Astrophysics Data System (ADS)

Jonathan, Enock

2008-06-01

While human sweat secretion is accepted as a mechanism by which the body cools off, excessive sweating (hyperhidrosis) is now appreciated as a medical condition and the primary site for diagnosis is the palm of the hand. We propose sweat film layer thickness as a potential clinical diagnostic parameter when screening for excessive sweating. In this preliminary study we demonstrate the usefulness of Fourier-domain optical coherence tomography (FD-OCT) for measurement of sweat film thickness in vivo with micron-scale resolution on the hand of a human volunteer. FD-OCT has a superior image acquisition time and identification of active sweat glands, ducts and pores is also possible.

Morvan chorea is an antibody-mediated limbic encephalopathy characterized by severe insomnia, mental confusion, hallucinations, enacted dreams, hyperhidrosis, and neuromyotonia. In a 78 years old man presenting with progressive insomnia apathy and depression, a video-polysomnogram documented enacted dreams mimicking daily life activity (oneiric stupor). This finding led us to perform a search for serum antibodies to voltage-gated K+ channels, which was positive. A diagnosis of Morvan chorea was done. The patient underwent plasma exchange with complete resolution of the clinical picture. Oneiric stupor may represent a useful precocious diagnostic marker in Morvan chorea.

González-Piana, Mauricio; Fabián, Daniel; Piccardo, Andrea; Chalar, Guillermo

2017-10-01

This study analyzed the temporal dynamics of total microcystin LR concentrations between the years of 2012 and 2015 in the Bonete, Baygorria and Palmar hydroelectric generation reservoirs in the central region of the Negro River, Uruguay. The three reservoirs showed differents total microcystin LR concentration, with no significant differences among them. Over 20 sampling dates, the three reservoirs exhibited total microcystin LR concentrations on eight occasions that corresponded to a slight to moderate human health risk according to WHO guideline values for recreational waters. By determining the concentration of microcystin LR in cyanobacterial biomass, we identified cyanobacterial populations that occurred over time with varying degrees of toxin production (maximal 85.4 µg/mm 3 ). The microcystin LR concentration in Bonete was positively correlated with temperature (r = 0.587) and cyanobacterial biomass (r = 0.736), in Baygorria with cyanobacterial biomass (r = 0.521), and in Palmar with temperature (r = 0.500) and negatively correlated with ammonia (r = -0.492). Action is needed to reduce the presence of toxic cyanobacteria in these systems. A decrease in the use of agrochemicals and management changes in the reservoir basins could be successful long-term measures.

Severe allergic contact dermatitis resulting from occupational exposure to tincture of benzoin aerosol spray in an anesthesiologist.

Klein, Thomas G; Woehlck, Harvey J; Pagel, Paul S

2009-01-01

We describe the clinical presentation and management of an anesthesiologist who developed a severe allergic contact dermatitis resulting from occupational exposure to tincture of benzoin aerosol spray. A previously healthy male anesthesiologist with a small laceration between his right thumb and forefinger used a tincture of benzoin aerosol spray to improve adhesion of a small bandage immediately before performing a spinal anesthetic. He had previously used benzoin for skin reinforcement on several occasions during weight-lifting. The anesthesiologist experienced severe pruritus in the affected hand 48 h after benzoin exposure. A well-demarcated, bright red erythematous confluent vesicular dermatitis with and without painful hemorrhagic bullae erupted on the palmar and dorsal surfaces, respectively, of his hand, accompanied by pronounced edema. The palmar bullae were drained with several small incisions and the anesthesiologist was treated with intravenous methylprednisolone. He was unable to work for 10 days while the dermatitis gradually resolved. The case emphasizes that occupational exposure to benzoin represents a potential risk for operating room personnel who may be susceptible to cutaneous delayed hypersensitivity-mediated allergic reactions as a result of previous exposure to benzoin or chemically related cross-reacting substances.

2015-02-01

To compare stability and range of motion after hemi-hamate reconstruction versus volar plate arthroplasty in a biomechanical proximal interphalangeal (PIP) joint fracture-dislocation model. Eighteen digits from 6 cadaver hands were tested. We created defects of 40%, 60%, and 80% in the palmar base of each digit's middle phalanx, simulating an acute PIP joint fracture-dislocation. Each defect scenario was reconstructed with a hemi-hamate arthroplasty followed by a volar plate arthroplasty. A computer-controlled mechanism was used to bring each digit's PIP joint from full extension to full flexion via the digital tendons in each testing state, and in the intact state. During each testing scenario we collected PIP joint cinedata in a true lateral projection using mini-fluoroscopy. A digital radiography program was used to measure the amount of middle phalanx dorsal translation (subluxation) in full PIP joint extension. We recorded the angle at which subluxation, if present, occurred during each testing scenario. Average dorsal displacement of the middle phalanx in relation to the proximal phalanx was 0.01 mm for the hemi-hamate reconstructed joints and -0.03 mm for the volar plate arthroplasty, compared with the intact state. Flexion contractures were noted in each of the specimens reconstructed with volar plate arthroplasty. Degree of contracture was directly correlated with defect size, averaging 20° for 40% defects, 35° for 60% defects, and 60° for 80% defects. We observed no flexion contractures in the hemi-hamate reconstructions. Surgeons can use both hemi-hamate and volar plate arthroplasty to restore PIP joint stability following a fracture dislocation with a large middle phalanx palmar base defect. Use of volar plate arthroplasty led to an increasing flexion contracture as the middle phalanx palmar base defect increased. Clinicians can use the information from this study to help with surgical decision-making and patient education. Copyright © 2015

Duloxetine, Pregabalin, and Duloxetine Plus Gabapentin for Diabetic Peripheral Neuropathic Pain Management in Patients With Inadequate Pain Response to Gabapentin: An Open-Label, Randomized, Noninferiority Comparison

OBJECTIVE: To determine whether duloxetine is noninferior to (as good as) pregabalin in the treatment of pain associated with diabetic peripheral neuropathy. PATIENTS AND METHODS: We performed a 12-week, open-label study of patients with diabetic peripheral neuropathic pain who had been treated with gabapentin (≥900 mg/d) and had an inadequate response (defined as a daily pain score of ≥4 on a numerical rating scale [0-10 points]). The first patient was enrolled on September 28, 2006, and the last patient visit occurred on August 26, 2009. Patients were randomized to duloxetine monotherapy (n=138), pregabalin monotherapy (n=134), or a combination of duloxetine and gabapentin (n=135). The primary objective was a noninferiority comparison between duloxetine and pregabalin on improvement in the weekly mean of the diary-based daily pain score (0- to 10-point scale) at end point. Noninferiority would be declared if the mean improvement for duloxetine was no worse than the mean improvement for pregabalin, within statistical variability, by a margin of –0.8 unit. RESULTS: The mean change in the pain rating at end point was –2.6 for duloxetine and –2.1 for pregabalin. The 97.5% lower confidence limit was a –0.05 difference in means, establishing noninferiority. As to adverse effects, nausea, insomnia, hyperhidrosis, and decreased appetite were more frequent with duloxetine than pregabalin; insomnia, more frequent with duloxetine than duloxetine plus gabapentin; peripheral edema, more frequent with pregabalin than with duloxetine; and nausea, hyperhidrosis, decreased appetite, and vomiting, more frequent with duloxetine plus gabapentin than with pregabalin. CONCLUSION: Duloxetine was noninferior to pregabalin for the treatment of pain in patients with diabetic peripheral neuropathy who had an inadequate pain response to gabapentin.

Recently, superior cervical ganglionectomy has been performed to investigate a variety of scientific topics from regulation of intraocular pressure to suppression of lingual tumour growth. Despite these recent advances in our understanding of the functional mechanisms underlying superior cervical ganglion (SCG) growth and development after surgical ablation, there still exists a need for information concerning the quantitative nature of the relationships between the removed SCG and its remaining contralateral ganglion and between the remaining SCG and its modified innervation territory. To this end, using design-based stereological methods, we have investigated the structural changes induced by unilateral ganglionectomy in sheep at three distinct timepoints (2, 7 and 12 weeks) after surgery. The effects of time, and lateral (left-right) differences, were examined by two-way analyses of variance and paired t-tests. Following removal of the left SCG, the main findings were: (i) the remaining right SCG was bigger at shorter survival times, i.e. 74% at 2 weeks, 55% at 7 weeks and no increase by 12 weeks, (ii) by 7 weeks after surgery, the right SCG contained fewer neurons (no decrease at 2 weeks, 6% fewer by 7 weeks and 17% fewer by 12 weeks) and (iii) by 7 weeks, right SCG neurons were also larger and the magnitude of this increase grew substantially with time (no rise at 2 weeks, 77% by 7 weeks and 215% by 12 weeks). Interaction effects between time and ganglionectomy-induced changes were significant for SCG volume and mean perikaryal volume. These findings show that unilateral superior cervical ganglionectomy has profound effects on the contralateral ganglion. For future investigations, it would be interesting to examine the interaction between SCGs and their innervation targets after ganglionectomy. Is the ganglionectomy-induced imbalance between the sizes of innervation territories the milieu in which morphoquantitative changes, particularly changes in perikaryal volume and neuron number, occur? Mechanistically, how would those changes arise? Are there any grounds for believing in a ganglionectomy-triggered SCG cross-innervation and neuroplasticity? Copyright © 2011 ISDN.

Endoscopic thoracic sympathectomy has been used successfully in the treatment of blushing, excessive sweating, and social phobia. However, the adverse effects of endoscopic thoracic sympathectomy are more severe and frequent than the adverse effects of endoscopic sympathetic block (ESB). The use of different blocking levels for different indications in ESB according to the Lin-Telaranta classification further decreases the postoperative adverse effects. However, there are few data on the long-term results of ESB performed using the Lin-Telaranta classification. Ninety-five patients (55 men, 40 women) were interviewed by before the surgery using our routine questionnaire, and the same questionnaire was answered postoperatively by the patients. In addition, a long-term follow-up questionnaire was sent to all patients whose address was known. Forty-seven patients (24 men, 23 women) answered to this questionnaire. The Davidson brief social phobia scale and the Liebowitz quality of life scale were used. Patients were divided to 3 categories: category 1, patients with sweating problems; category 2, patients with blushing; and category 3, and patients with symptoms other than sweating or blushing. Among patients in category 1, social phobia decreased from 12.43 to 6.71 (p = 0.004), in category 2 from 13.97 to 7.69 (p < 0.001), and in category 3 from 13.18 to 9.64 (p = 0.007) during long-term follow-up. Among patients with severe sweating problems preoperatively, sweating decreased from 2.50 to 1.29 (p = 0.003) among patients in category 1 and from 1.86 to 1.16 (p < 0.001) among patients in category 2. Among patients with unbearable blushing, blushing decreased from 4 to 1.80 (p < 0.001). Patients got a clear help from ESB performed using the Lin-Telaranta classification to treat blushing, excessive sweating, and social phobia with and without physical symptoms. In addition, compensatory sweating increased only slightly.

A 20 years-old girl presented with multiple asymptomatic reddish vesicles on face for four years. It used to get worse in summer and was associated with localized hyperhidrosis. The lesions were notable for disappearance on diascopy. Histopathology from the vesicle showed mononuclear cell infiltration in the upper dermis, especially around eccrine sweat apparatus, along with dilatation of superficial capillaries and lymphatics. Based on clinical presentation and histopathology, diagnosis of Granulosis rubra nasi (GRN) was made. GRN usually resolves at puberty; however, rarely it may persist in adulthood. We here report a case of GRN having lesions persisting in adulthood. Moreover, she showed excellent response to topical tacrolimus, a finding not observed in literature.

Myokymia is one of the involuntary movements, which is characterized by undulatory muscle spasm, similar to the worm's crawl. Sometimes muscle pain, itchy sensation, dysautonomia and other symptoms are associated with it. Cases showing normal neurological findings are rare. Myokymia is caused by various diseases, such as, multiple sclerosis, hypothyroidism, Guillan-Barre syndrome and so on. Generally myokymia is classified into two types, i.e. limb myokymia and facial myokymia according to the site. On the other hand, myokymia with hyperhidrosis is known as Issacs syndrome. There are many opinions about the pathogenesis and mechanism in the myoneural junction, peripheral nerve or spinal cord, however these are not established. Further investigation of myokymia is expected.

1. Cell proliferation in the jejunal crypts, the colonic crypts and in dimethylhydrazine (DMH)-induced adenocarcinomata of rat colon was measured using a stathmokinetic technique. 2. Dibutryl cyclic adneosine monophosphate (dibutyryl cAMP) was found to inhibit cell proliferation in colonic crypts and in colonic adenocarcinomata. 3. Dibutryl cAMP at very high doses was found to inhibit jejunal crypt cell proliferation but at lower doses was found to accelerate jejunal crypt cell proliferation. 4. Neither bilateral adrenalectomy nor chemical sympathectomy was found to abolish the ability of dibutryl cAMP to stimulate jejunal crypt cell proliferation. 5. The present results are difficult to interpret in terms of known hormonal influences on cell proliferation in the tissues examined and of established actions, of these hormones on cyclic nucleotide metabolism in other tissues.

A wearable sensor for unobtrusive, long-term assessment of electrodermal activity.

Poh, Ming-Zher; Swenson, Nicholas C; Picard, Rosalind W

2010-05-01

Electrodermal activity (EDA) is a sensitive index of sympathetic nervous system activity. Due to the lack of sensors that can be worn comfortably during normal daily activity and over extensive periods of time, research in this area is limited to laboratory settings or artificial clinical environments. We developed a novel, unobtrusive, nonstigmatizing, wrist-worn integrated sensor, and present, for the very first time, a demonstration of long-term, continuous assessment of EDA outside of a laboratory setting. We evaluated the performance of our device against a Food and Drug Administration (FDA) approved system for the measurement of EDA during physical, cognitive, as well as emotional stressors at both palmar and distal forearm sites, and found high correlations across all the tests. We also evaluated the choice of electrode material by comparing conductive fabric with Ag/AgCl electrodes and discuss the limitations found. An important result presented in this paper is evidence that the distal forearm is a viable alternative to the traditional palmar sites for EDA measurements. Our device offers the unprecedented ability to perform comfortable, long-term, and in situ assessment of EDA. This paper opens up opportunities for future investigations that were previously not feasible, and could have far-reaching implications for diagnosis and understanding of psychological or neurological conditions.

Trabecular architecture of the manual elements reflects locomotor patterns in primates.

PubMed

Matarazzo, Stacey A

2015-01-01

The morphology of trabecular bone has proven sensitive to loading patterns in the long bones and metacarpal heads of primates. It is expected that we should also see differences in the manual digits of primates that practice different methods of locomotion. Primate proximal and middle phalanges are load-bearing elements that are held in different postures and experience different mechanical strains during suspension, quadrupedalism, and knuckle walking. Micro CT scans of the middle phalanx, proximal phalanx and the metacarpal head of the third ray were used to examine the pattern of trabecular orientation in Pan, Gorilla, Pongo, Hylobates and Macaca. Several zones, i.e., the proximal ends of both phalanges and the metacarpal heads, were capable of distinguishing between knuckle-walking, quadrupedal, and suspensory primates. Orientation and shape seem to be the primary distinguishing factors but differences in bone volume, isotropy index, and degree of anisotropy were seen across included taxa. Suspensory primates show primarily proximodistal alignment in all zones, and quadrupeds more palmar-dorsal orientation in several zones. Knuckle walkers are characterized by having proximodistal alignment in the proximal ends of the phalanges and a palmar-dorsal alignment in the distal ends and metacarpal heads. These structural differences may be used to infer locmotor propensities of extinct primate taxa.

2007-11-01

Hypothenar hammer syndrome (HHS) is an uncommon form of secondary Raynaud phenomenon, occurring mainly in subjects who use the hypothenar part of the hand as a hammer; the hook of the hamate strikes the superficial palmar branch of the ulnar artery in the Guyon space, leading to occlusion and/or aneurysm of the ulnar artery. In patients with HHS, such injuries of the palmar ulnar artery may lead to severe vascular insufficiency in the hand with occlusion of digital artery. To date, only a few series have analyzed the long-term outcome of patients with HHS. This prompted us to conduct the current retrospective study to 1) evaluate the prevalence of HHS in patients with Raynaud phenomenon and 2) assess the short-term and long-term outcome in patients with HHS. From 1990 to 2006, 4148 consecutive patients were referred to the Department of Internal Medicine at the University of Rouen medical center for evaluation of Raynaud phenomenon using nailfold capillaroscopy. HHS was diagnosed in 47 of these 4148 patients (1.13% of cases).Forty-three patients (91.5%) had occupational exposure to repetitive palmar trauma. The more common occupations were factory worker (21.3%), mason (12.8%), carpenter (10.6%), and metal worker (10.6%); the mean duration of occupational exposure to repetitive palmar trauma at HHS diagnosis was 21 years. One patient (2.1%) had recreational exposure (aikido training) to repetitive trauma of the palmar ulnar artery, and 3 other patients (6.4%) developed HHS related to a single direct injury to the hypothenar area. Clinical manifestations were more often unilateral (87.2%) involving the dominant hand (93%). HHS complications included digital ischemic symptoms (ischemia: n = 21, necrosis: n = 20) and irritation of the sensory branch of the ulnar nerve (n = 11). In HHS patients, angiography demonstrated occlusion of the ulnar artery in the area of the Guyon space (59.6%), aneurysm of the ulnar artery in the area of the Guyon space (40.4%), and embolic

To determine the safety and efficacy of collagenase clostridium histolyticum (CCH) injection for the treatment of palmar Dupuytren disease nodules. In this 8-week, double-blind trial, palpable palmar nodules on one hand of adults with Dupuytren disease were selected for treatment. Patients were randomly assigned using an interactive web response system to receive a dose of 0.25 mg, 0.40 mg, or 0.60 mg (1:1:1 ratio) and then allocated to active treatment (CCH) or placebo (4:1 ratio). All patients and investigators were blinded to treatment. One injection was made in the selected nodule on Day 1. Caliper measurements of nodule length and width were performed at screening and at Weeks 4 and 8. Investigator-reported nodular consistency and hardness were evaluated at baseline and Weeks 1, 4, and 8. Investigator-rated patient improvement (1 [very much improved] to 7 [very much worse]) and patient satisfaction were assessed at study end. In the efficacy population (n = 74), percentage changes in area were significantly greater with CCH 0.40 mg (-80.1%, P = 0.0002) and CCH 0.60 mg (-78.2%, P = 0.0003), but not CCH 0.25 mg (-58.3%, P = 0.079), versus placebo (-42.2%) at post-treatment Week 8. Mean change in nodular consistency and hardness were significantly improved with CCH versus placebo at Weeks 4 and 8 (P ≤ 0.0139 for all). At Week 8, investigator global assessment of improvement was significantly greater with CCH 0.40 mg and 0.60 mg (P ≤ 0.0014) but not statistically significant with CCH 0.25 mg versus placebo (P = 0.13). Most patients were "very satisfied" or "quite satisfied" with CCH 0.40 mg and 0.60 mg. Contusion/bruising (50.0% to 59.1%) was the most common adverse event with CCH treatment. In patients with Dupuytren disease, a single CCH injection significantly improved palmar nodule size and hardness. The safety of CCH was similar to that observed previously in patients with Dupuytren contracture. ClinicalTrials.gov identifier: NCT

Permeation of fingerprints through laboratory gloves.

Repeated controlled tests have shown that impressions from laboratory gloves will print onto optical components in 20 to 40 min and, in some cases, sooner. Careful testing demonstrated that palmar sweat passed through the glove material; the problem was not that gloves conform to the friction ridges of the fingers and then transfer some contaminant. The problem can be alleviated to a great extent by wearing thin cotton gloves like those commonly used in the film industry.

Neuromuscular electrical stimulation has been used in upper limb rehabilitation towards restoring motor hand function. In this work, an 8 channel microcomputer controlled stimulator with monophasic square voltage output was used. Muscle activation sequences were defined to perform palmar and lateral prehension and power grip (index finger extension type). The sequences used allowed subjects to demonstrate their ability to hold and release objects that are encountered in daily living, permitting activities such as drinking, eating, writing, and typing.

A method to locate the radial digital nerve of the index finger.

The radial digital nerve of the index finger is susceptible to injury during penetrating trauma or elective release of the A1 pulley. The intersection of a line drawn down the midline of the index finger and the proximal palmar crease identifies the location of the radial digital nerve. This method of identifying the topography of the nerve should assist the surgeon in determining the likelihood of injury after penetrating trauma, and preventing injury during elective procedures.

We report the case of a 50-year-old female who suffered from severe palmar and plantar pustulosis. During treatment with acitretin, a novel oral retinoid, which is the main derivative of etretinate, the patient developed a severe hepatotoxic reaction. Subsequent histological studies strongly suggested the development of liver cirrhosis. Reversible elevation of serum aminotransferase values during treatment with acitretin has been reported. However, the present observation indicates that severe hepatotoxic injury may also follow treatment with this agent.

Gorlin-Goltz syndrome or nevoid basal cell carcinoma syndrome is a rare hereditary autosomal-dominant disorder characterized by multiple basal cell carcinomas in young patients, odontogenic keratocysts, palmar or plantar pits, calcification of the falx cerebri and skeletal malformations. This syndrome is due to mutations in PTCH1 (patched homolog 1 da Drosophila), a tumor suppressor gene. Diagnostic criteria were defined by Evans, revised by Kimonis and include major and minor criteria. The authors review in particular the neuroradiological and maxillofacial characteristics of the syndrome. The authors describe the clinical presentation of two children with Gorlin-Goltz syndrome without affected first degree relatives. In both the clinical suspicion of the syndrome is raised by the presence of multiple odontogenic cysts surgically removed. Histopathological exam revealed keratocysts. None of the patients has basal cell carcinomas but both present with skeletal anomalies, namely marked pectus deformity. The absence of major diagnostic criteria like basal cell carcinomas or palmar or plantar pits in young patients delay the early diagnosis and the correct screening for medulloblastoma, basal cell carcinomas and cardiac fibromas. Odontogenic keratocysts are the most consistent clinical finding in Gorlin-Goltz syndrome in the first one or two decades of life. These patients are very sensitive to ionizing radiation, being able to develop basal cell carcinomas and meningiomas. Treatment should accomplish the complete resection of the tumors.

To report the MR imaging findings of painful injured metacarpophalangeal (MCP) joints of the fingers. MR imaging of 39 injured MCP joints in 38 patients was performed after a mean delay of 8.8 months. The MR images were obtained with the fingers in extended and flexed positions using T2-weighted and T1-weighted sequences before and after intravenous injection of a gadolinium compound. Ten patients were treated surgically. Mean clinical follow-up was 1.8 years. Tears of the collateral ligaments were the most common lesion (30/39), most being radial in location. Contrast-enhanced axial T1-weighted images with the MCP joint in a flexed position showed these lesions optimally. Ten tears were partial and 20 were complete. In 13 patients, MR images showed 17 associated lesions including injuries of the extensor hood (10/17), interosseous tendon (3/17), palmar plate (3/17), and an osteochondral lesion (1/17). Sagittal MR images were essential to highlight palmar plate tears. Partial or complete tears of the collateral ligaments are prevalent MR imaging findings in patients with chronic disability resulting from injuries to the MCP joints. Although conservative treatment generally is sufficient for isolated injuries of the collateral ligaments, surgical repair is often required in cases of more extensive injuries. MR imaging may clearly delineate associated lesions of and about the MCP joints.

An elastic mechanical counter pressure (MCP) glove for spacesuits is under development. In this study we compared handgrip and pinch grip strength levels for the MCP glove and the current extravehicular mobility unit (EMU) gas-pressurized glove. We employed handgrip and pinch grip dynamometers to assess strength levels and von Frey monofilaments to evaluate hand sensitivity. Tests were conducted with the gloved hand inserted in an evacuation chamber at 200 mmHg below atmospheric pressure to simulate conditions in space. Average bare hand strength was 463 N and decreased to 240 N for EMU and 250 N for MCP. Pinch grip and key grip testing showed no difference among conditions. However, there was a significant decrease in palmar grip strength from 111 N barehanded to 67 N in both gloves. Barehanded endurance time was 160 s and dropped to 63 and 69 s for EMU and MCP, respectively. Sensitivity was significantly better for MCP compared with the EMU. The MCP glove improved hand sensitivity when compared with the EMU glove and performed as well as the EMU glove in terms of overall handgrip strength, endurance at 25% of maximum handgrip strength, pinch grip, palmar grip, and key grip tests. Improvements in fabric composition and glove design may further improve ergonomic and other functional parameters of the MCP glove.

Dupuytren's disease susceptibility gene, EPDR1, is involved in myofibroblast contractility.

Dupuytren's Disease is a common disorder of the connective tissue characterized by progressive and irreversible fibroblastic proliferation affecting the palmar fascia. Progressive flexion deformity appears over several months or years and although usually painless, it can result in a serious handicap causing loss of manual dexterity. There is no cure for the disease and the etiology is largely unknown. A genome-wide association study of Dupuytren's Disease identified nine susceptibility loci with the strongest genetic signal located in an intron of EPDR1, the gene encoding the Ependymin Related 1 protein. Here, we investigate the role of EPDR1 in Dupuytren's Disease. We research the role of EPDR1 by assessing gene expression in patient tissue and by gene silencing in fibroblast-populated collagen lattice (FPCL) assay, which is used as an in vitro model of Dupuytren's contractures. The three alternative transcripts produced by the EPDR1 gene are all detected in affected Dupuytren's tissue and control unaffected palmar fascia tissue. Dupuytren's tissue also contracts more in the FPCL paradigm. Dicer-substrate RNA-mediated knockdown of EPDR1 results in moderate late stage attenuation of contraction rate in FPCL, implying a role in matrix contraction. Our results suggest functional involvement of EPDR1 in the etiology of Dupuytren's Disease. Copyright © 2016. Published by Elsevier Ireland Ltd.

Mindfulness-based cognitive hypnotherapy integrates mindfulness, cognitive-behavioral therapy, and hypnotherapy to improve physical, emotional, mental, and/or spiritual aspects of skin disorders. Meditation, including mindfulness meditation, and hypnosis both utilize trance phenomena to help produce focalization and specific improvements in skin disorders through psycho-neuro-endocrine-immunologic mechanisms. Hypnosis, cognitive hypnotherapy, focused meditation, and mindfulness meditation are discussed with respect to improving various skin disorders including acne, acne excoriée, alopecia areata, atopic dermatitis, congenital ichthyosiform erythroderma, dyshidrotic dermatitis, erythema nodosum, erythromelalgia, furuncles, glossodynia, herpes simplex, hyperhidrosis, ichthyosis vulgaris, lichen planus, neurodermatitis, nummular dermatitis, postherpetic neuralgia, prurigo nodularis, pruritus, psoriasis, rosacea, trichotillomania, urticaria, verruca vulgaris, and vitiligo. Their integration into mindfulness-based cognitive hypnotherapy is then discussed and illustrated with improvement in a patient with systemic lupus erythematosus.

Granulosis rubra nasi is a rare disorder of the eccrine glands, inherited as an autosomal dominant trait. It is clinically characterized by hyperhidrosis of the central part of the face, most conspicuous on the tip of the nose, followed by appearance of diffuse erythema over the nose, cheeks, chin, and upper lip. It is commonly seen in childhood, but can also occur in adults. This is a case report of a 27-year-old male patient who presented with excessive sweating over the nose. Physical examination of the nose revealed erythema and multiple telangiectatic vesicles. Biopsy findings supported the diagnosis of granulosis rubra nasi. This case is being reported for its rarity since to the best of our knowledge, it has not been reported in Indian subjects so far.

Sympathectomy has been achieved by a variety of methods but each has its limitations. These include lack of tissue specificity, incomplete lesioning, and the age range of susceptibility to the lesioning. To circumvent these drawbacks, an immunotoxin was constructed using a monoclonal antibody against the noradrenergic specific enzyme dopamine beta-hydroxylase (D beta H) coupled via a disulfide bond to saporin, a ribosomal inactivating protein. Three days after intravenous injection of the anti-D beta H immunotoxin (50 micrograms) into adult Sprague-Dawley rats, 66% of neurons in the superior cervical ganglia were chromatolytic. Superior cervical ganglia neurons were poisoned in 1 day old and 1 week old (86% of neurons) neonatal rats following subcutaneous injection of 3.75 and 15 micrograms, respectively. The anti-D beta H immunotoxin will be a useful tool in the study of the peripheral noradrenergic system in adult and neonatal animals.

Nerves are a common feature of the microenvironment, but their role in tumor growth and progression remains unclear. We found that the formation of autonomic nerve fibers in the prostate gland regulates prostate cancer development and dissemination in mouse models. The early phases of tumor development were prevented by chemical or surgical sympathectomy and by genetic deletion of stromal β2- and β3-adrenergic receptors. Tumors were also infiltrated by parasympathetic cholinergic fibers that promoted cancer dissemination. Cholinergic-induced tumor invasion and metastasis were inhibited by pharmacological blockade or genetic disruption of the stromal type 1 muscarinic receptor, leading to improved survival of the mice. A retrospective blinded analysis of prostate adenocarcinoma specimens from 43 patients revealed that the densities of sympathetic and parasympathetic nerve fibers in tumor and surrounding normal tissue, respectively, were associated with poor clinical outcomes. These findings may lead to novel therapeutic approaches for prostate cancer.

Gorlin-Goltz syndrome is a rare autosomal-dominant syndrome related to mutation in "Patched" tumour suppressor gene on chromosome 9. Basocellular carcinomas, odontogenic keratocysts, palmar and/or plantar pits and ectopic calcifications of the falx cerebri are its major features, along with more than 100 minor features. Odontogenic cysts, notorious for recurrence, can make endotracheal intubation difficult, requiring modification of the standard intubation technique. We report such a case managed successfully by awake fibreoptic intubation. Direct laryngoscopy under anaesthesia later confirmed that it was a good decision.

Nevoid basal cell carcinoma syndrome (NBCCS) is rare in black persons. We describe an 11-year-old black boy with NBCCS who presented with exotropia and a painful, expanding, cystic mass in the left posterior alveolar ridge. Further examination revealed odontogenic keratocysts with palmar and plantar pitting. Less than 5% of reported patients with NBCCS are black. To our knowledge, this is the first report of a black patient with NBCCS presenting with exotropia and an impacted molar displaced into the orbit by an odontogenic keratocyst.

Skin and soft-tissue architecture of the palm are unique. Coverage of extensive soft-tissue defects restoring the functional capacity of the palm remains a challenging task. Anatomic restoration with skin from another area is hardly possible. In manual labourers, reconstruction of mechanical soft-tissue stability is required in addition to sensation, range of motion and grip strength. Sensate fasciocutaneous flaps bear disadvantages of tissue mobility, shifting and bulkiness. Published criteria for defect-related flap selection are sparse. Defect analysis (anatomy, units of tactile gnosis, individual parameters) provides information to weigh needs for sensation or tissue stability, influencing selection of most appropriate procedures. We distinguished 4 units: hypothenar (H), thenar (T) and central palm (Z). (Z) consists of a central palmar unit (c') and the distal palm (d'). Individual parameters (age, profession, dominant hand, psychosocial aspects) were also considered. Units (T) and (H), regions of secondary touch, demand protective sensation by applying sensate fasciocutaneous flaps. In labourers tactile gnosis in (Z) is of less, tissue stability of greater value. An extensive palmar defect (9×13 cm, affecting unit (Z), partially affecting units (T) and (H), of the dominant hand) with combined vessel, nerve, tendon injuries (male labourer, 21 years) was covered after defect analysis with a free gracilis muscle flap and a glabrous intermediate (0.5 mm) thickness skin graft from the instep region. 29 months postoperatively anatomic conditions of palmar soft tissue (Vancouver scar scale: 1), high mechanical soft-tissue stability including normal hand function were evident. Semmes Weinstein testing showed positive pressure sensation. Professional reintegration after 5 months was possible. Defect coverage of the palm must not consist of merely providing sensate vascularised tissue. The most appropriate procedure can be derived from careful defect analysis

This study involves the evaluation of pre-purchase radiographic studies of South African Thoroughbred yearlings. Radiographic changes were recorded and compared with similar international studies. The study differs from other studies in that a lower prevalence of pedal osteitis (1.26%), dorsal osteochondral fragmentation of the metatarsophalangeal joint (1.60%), distal metacarpal sagittal ridge changes (15.7%), ulnar carpal bone lucencies (8.33%), carpal osteophytes (1.19%), distal intertarsal and tarsometatarsal joint radiographic changes (9.92%), tarsal osteochondrosis lesions (4.40%) and stifle osteochondrosis lesions (0.4%) was found. The prevalence of dorsal osteochondral fragments in the metacarpophalangeal joint was similar to other studies (1.60%). A higher prevalence of vascular channels as well as irregular borders and lucencies was evident in the proximal sesamoid bones. There was a higher prevalence of palmar metacarpophalangeal and plantar metatarsophalangeal osteochondral fragments (2% and 7.10% respectively). Palmar metacarpal disease, metacarpal supracondylar lysis, proximal sesamoid bone fractures and carpal osteochondral fragmentation were absent in the current study. Additional findings recorded in the current study were proximal interphalangeal joint hyperextension (left front 15.13%, right front 18.91%), the solar angle (right front 2.38 degrees, left front 2.79 degrees), the prevalence of carpal bone 1 (30.95%) and carpal bone 5 (1.59%). Management, nutrition and genetics in the various groups of Thoroughbred yearlings should be further investigated in order to explain the reasons for the differences recorded in the current study.

Fibromatosis represents a wide group of benign, locally proliferative disorders of fibroblasts. Dupuytren's disease is a benign proliferative disease of palmar aponeurosis which usually affects adults between 40 and 60 years of age. Ledderhose's disease or plantar fibromatosis is plantar equivalent of Dupuyten's disease most often affecting middle-aged and older men, usually bilateral, represented with painless nodule in the medial division of plantar fascia. We presented a 19-year old adolescent that turned to a plastic surgeon complaining to his small finger contracture. He noticed palmar thickening with nodule over the metacarpophalangeal joint of small finger of his right hand when he was 16 years old. A year later a finger started to band. During physical checkup we noticed plantar nodule that also had his father and grandmother. Magnetic resonance and tumor biopsy confirmed a suspicion on plantar fibromatosis - Ledderhose's disease. Clinical exam of the hand clearly led to a conclusion that the patient had Dupuytren's contracture with pretendinous cord over the small finger flexor tendons and lack of extension of proximal interphalangeal (PIP) joint. On the extensor side of the PIP joints there were Garrod's nodes. The patient refused surgical treatment of plantar tumor, but agreed to surgical correction of finger contracture. Despite the fact that Dupuytren's disease and plantar fibromatosis are diseases of adults, the possibility of conjoint appearance of these forms of fibromatosis in adolescent period of life should be kept in mind especially in patients with strong genetic predisposition.

An analysis of the input-output properties of neuroprosthetic hand grasps.

We measured the input-output properties of the hand grasps of 14 individuals with tetraplegia at the C5/C6 level who had received an implanted upper limb neuroprosthesis. The data provide a quantitative description of grasp-opening and grasp-force control with neuroprosthetic hand grasp systems. Static properties were estimated by slowly ramping the command (input) from 0 to 100%. A hand-held sensor monitored the outputs: grasp force and grasp opening. Trials were performed at different wrist positions, with two different-sized objects being held, and with both grasp modes (lateral and palmar grasps). Larger forces were produced when grasping larger objects, and greater opening was achieved with the wrist in flexion. Although active grasp force increased with wrist extension, it was not significant statistically. Lateral grasp produced larger forces than the palmar grasp. The command range can be divided into a portion that controls grasp opening and a portion that controls grasp force. The portion controlling force increased with spacer size, but did not depend significantly on grasp mode or wrist position. The force-command relationships were more linear than the position-command relationships. Grasp opening decreased significantly over a one-year period, while no significant change in grasp force was observed. These quantitative descriptions of neuroprosthetic hand grasps under varying conditions provide useful information about output capabilities that can be used to gauge the effectiveness of different control schemes and to design future control systems.

2015-03-01

To determine whether directly measured arterial blood pressure differs among anatomic locations and whether arterial blood pressure is influenced by body position. 33 client-owned dogs undergoing anesthesia. Dogs undergoing anesthetic procedures had 20-gauge catheters placed in both the superficial palmar arch and the contralateral dorsal pedal artery (group 1 [n = 20]) or the superficial palmar arch and median sacral artery (group 2 [13]). Dogs were positioned in dorsal recumbency, and mean arterial blood pressure (MAP), systolic arterial blood pressure (SAP), and diastolic arterial blood pressure (DAP) were recorded for both arteries 4 times (2-minute interval between successive measurements). Dogs were positioned in right lateral recumbency, and blood pressure measurements were repeated. Differences were detected between pressures measured at the 2 arterial sites in both groups. This was especially true for SAP measurements in group 1, in which hind limb measurements were a mean of 16.12 mm Hg higher than carpus measurements when dogs were in dorsal recumbency and 14.70 mm Hg higher than carpus measurements when dogs were in lateral recumbency. Also, there was significant dispersion about the mean for all SAP, DAP, and MAP measurements. Results suggested that arterial blood pressures may be dependent on anatomic location and body position. Because this may affect outcomes of studies conducted to validate indirect blood pressure measurement systems, care must be used when developing future studies or interpreting previous results.

Chronic ischemia of the hand in the setting of atherosclerotic disease is a challenging problem that leads to serial amputations and significant morbidity. Salvage using an in situ venous bypass has been described. In selected cases, leaving the vein in situ for bypass allows a good size match for anastomosis at the wrist or palmar arch. Due to the rarity of the condition, there is a paucity of data regarding the efficacy of this technique. Outcomes in 23 consecutive patients that underwent a total of 25 in situ vein grafts over a 16-year period were retrospectively reviewed. Eighteen were men and 5 were women with a mean age of 61 years. Target vessels at the wrist or palmar arch were identified on preoperative vascular imaging. The cephalic vein (n = 19, 76%) was most commonly used followed by the basilic vein (n = 6, 24%). Overall patency rate at a mean follow-up period of 12.1 months was 92%. Success as determined by both symptomatic improvement and resolution of the ischemic changes or toleration of revision amputation was achieved in 16 (64%) cases. Postoperative complications occurred in ten cases (40 %). Progression of ischemia occurred in 7 cases (28 %) and 3 (12 %) of these cases required a hand amputation. In situ vein grafts in the upper extremity offer good short-term patency rates and can be used for salvage of chronic hand ischemia.

Study of two patients with craniosynostosis and deletions of 11q: One with features of Saethre-Chotzen syndrome and the other with concomitant partial trisomy 4q

Partial monosomy 11q is associated with metopic craniosynostosis and trigonocephaly. Prominant features in the over 30 reported cases include downslanting palpebral fissures, epicanthal folds, hypertelorism, ptosis, wide/depressed nasal bridge, low set malformed ears, downturned mouth, micro/retrognathia, digital and cardiac anomalies and psychomotor retardation. We evaluated two patients referred for abnormal head shape. The first carried a diagnosis of Saethre-Chotzen syndrome due to brachycephaly, facial asymmetry, ptosis, cupped ears, sundactyly of 2nd and 3rd digits, developmental delay, and VSD. Karyotype revealed 46,XY,del(11)(q24.1{yields}qter). No abnormality was noted of chromosome 7p, where the Saethre-Chotzen syndrome locus has been mapped. This suggests genetic heterogeneitymore » for this condition. The second patient had no prior diagnosis. He had trigonocephaly, bilateral cryptorchidism and inguinal hernias. He also had hypotelorism, epicanthal folds, synophrys, posteriorly rotated ears, horizontal crease below his lower lip, unilateral single palmar crease, mild soft tissue syndactyly and a shawl scrotum. His karyotype of 46,XY,-11,+der(11)t(4;11)(q31.3;q25) revealed both partial 11q monosomy and partial 4q trisomy (the latter associated with cryptorchidism, horizontal chin crease and single palmar crease). Deletions of 11q appear to produce a wide spectrum of defects, which may even mimic other known craniosynostotic conditions. Study of these patients may lead to the identification of new genes involved in craniofacial morphogenesis.« less

The response of horses, with solar pain in the dorsal or palmar aspect of the foot, to 6 or 10 ml local analgesic solution administered into the distal interphalangeal (DIP) joint was examined. Lameness was induced in 7 horses by creating solar pain in the dorsal aspect of one forefoot and, at another time, the palmar aspect of the other forefoot with set-screws inserted into a custom-made shoe. Horses were videotaped trotting before and after application of set-screws and, in separate trials, after 6 or 10 ml local analgesic solution was administered into the DIP joint. Lameness scores were assigned by examining videotaped gaits. Scores were significantly lower (P < 0.05) for horses with set-screws applied to the angles of the sole and receiving 10 ml, but not 6 ml, local analgesic solution into the DIP joint. Scores were significantly lower (P < 0.05) for all horses with set-screws in the dorsal margin of the sole receiving either volume of local analgesic solution. Analgesia of the DIP joint was less effective in desensitising the angles of the sole than in desensitising the dorsal margin of the sole, and 10 ml local analgesic solution was more effective than 6 ml in desensitising these regions. The response of horses with solar pain to local analgesic solution in the DIP joint was influenced by the volume administered and the region of sole affected.

Anaesthetic management in Gorlin-Goltz syndrome

PubMed Central

Gosavi, Kundan S; Mundada, Surbhi D

2012-01-01

Gorlin-Goltz syndrome is a rare autosomal-dominant syndrome related to mutation in “Patched” tumour suppressor gene on chromosome 9. Basocellular carcinomas, odontogenic keratocysts, palmar and/or plantar pits and ectopic calcifications of the falx cerebri are its major features, along with more than 100 minor features. Odontogenic cysts, notorious for recurrence, can make endotracheal intubation difficult, requiring modification of the standard intubation technique. We report such a case managed successfully by awake fibreoptic intubation. Direct laryngoscopy under anaesthesia later confirmed that it was a good decision. PMID:23087465

Modified McCash Technique for Management of Dupuytren Contracture.

Lesiak, Alex C; Jarrett, Nicole J; Imbriglia, Joseph E

2017-05-01

Despite recent advancements in the nonsurgical treatment for Dupuytren contracture, a number of patients remain poor nonsurgical candidates or elect for surgical management. The traditional McCash technique releases contractures while leaving open palmar wounds. Although successful in alleviating contractures, these wounds are traditionally large, transverse incisions across the palm. A modification of this technique has been performed that permits the surgeon to utilize smaller wounds while eliminating debilitating contractures.

Simões, Maria Inês; Marcão, Isabel; Toscano, Mário; Borges, Luís

2018-03-29

Hidradenocarcinoma is a rare neoplasm of the eccrine cells of the sweat glands, usually asymptomatic with slow growing and higher incidence between 50 and 80 years, occurring in both sexes and preferentially located in the palmar, plantar, frontal, axillary and nuchal regions. It has an aggressive behavior, with high rate of local recurrence and distance metastasis, associated with a poor prognosis. We present a case of hidradenocarcinoma of the scrotum manifested by lymph node metastasis through an exercise of clinical and histological differential diagnosis of an inguinal adenopathy in a young adult.

A new treatment for parrot beak deformity of the toe.

PubMed

Kurokawa, M; Isshiki, N; Inoue, K

1994-03-01

Two cases of congenital parrot beak deformity of the toe were treated by pushing back the nail plate, nailbed, matrix, and proximal skin fold in one piece as a flap. The proximal skin portion of this flap was deepithelialized to facilitate this shift, and thus no dog-ear deformity was produced. The distal skin defect of the pulp was covered by a palmar advancement flap. This method does not require augmentation of the fingertip or toetip and is very useful for correcting parrot beak deformities of the toes.

Dermatoglyphics: A Diagnostic Aid?

PubMed Central

Fuller, I. C.

1973-01-01

Dermatoglyphics of patients suffering from diabetes, schizophrenia, duodenal ulcer, asthma, and various cancers have been contrasted and significant differences in the digital ridge counts, maximum atd angles, and distal palmar loop ridge counts have been found. A discriminant analysis of the digital ridge counts was performed and the function was used to attempt differential diagnosis between these conditions on dermatoglyphic evidence alone. This diagnostic trial failed, and possible reasons for its failure are discussed. Attention is drawn to the possibility that prognostic implications of dermatoglyphics might be relevant to screening techniques. PMID:4714584

Molecular biology of botulinum neurotoxin serotype A: a cosmetic perspective.

PubMed

Eapen, Bell Raj

2008-09-01

Cosmetic use of botulinum neurotoxin serotype A (BoNT/A) involves low doses of toxin administered for facial wrinkles and hyperhidrosis. The structural and functional properties of BoNT/A can affect the degree and duration of effect. Actively using the injected muscle is favorable as it exposes more receptors to BoNT/A. Divided doses of BoNT/A at an interval of more than 3 days may be longer lasting than single dose by blocking nascent neuronal sprouts. Antibodies are unlikely to be effective in BoNT/A neutralization because of the large area of receptor interaction. Several commonly used drugs including zinc and chloroquine can interact with BoNT/A, necessitating dosage adjustment for optimum effect. Serotype E (BoNT/E) can emerge as an antidote for BoNT/A for cosmetic use.

Botulinum Toxin Use in Pediatric Plastic Surgery.

Fu, Katherine J; Teichgraeber, John F; Greives, Matthew R

2016-11-01

Botulinum toxin has increasingly become a prevalent treatment option for a wide range of conditions, many of which have their roots in plastic surgery and have been well studied. In adults, chronic headache, hyperhidrosis, and facial muscular hypertrophy have been effectively treated with botulinum toxin, and emerging studies have begun looking at its efficacy in children, as well. Successful treatment of spasticity and muscular contraction has allowed for the creation of safety profiles and dosage guidelines for botulinum toxin usage in children. The expanded indications for its use have since flourished in all arenas of pediatric care, including plastic surgery. Recent studies have described the use of botulinum toxin as an adjunct to the treatment of congenital torticollis and cleft lip. This review discusses the various applications of botulinum toxin for pediatric patients in the field of plastic surgery.

Le syndrome du QT long congénital est une maladie rythmique liée à une mutation génétique et caractérisée par un espace QT allongé sur l’électrocardiogramme, des arythmies malignes type torsade de pointe et fibrillation ventriculaire entraînant une mort subite. Les gènes impliqués dans ces mutations codent pour des sous unités des canaux ioniques responsables de l'activité électrique cardiaque. Le diagnostic est basé sur l’électrocardiogramme, une enquête familiale et l’étude génétique. Le traitement repose sur les bêtabloquants, la sympathectomie et le stimulateur cardiaque. Nous rapportons le cas d'un nourrisson de 2 ans retrouvé en état de mort apparente. Nous discutons de sa prise en charge initiale, de l'enquête familiale et de son suivi ultérieur. PMID:25667708

Adrenergic nerve fibres and mast cells: correlation in rat thymus.

PubMed

Artico, Marco; Cavallotti, Carlo; Cavallotti, Daniela

2002-10-21

The interactions between adrenergic nerve fibres and mast cells (MCs) were studied in the thymus of adult and old rats by morphological methods and by quantitative analysis of images (QAIs). The whole thymus was drawn in adult (12 months old) rats: normal, sympathectomized or electrostimulated. Thymuses from the above-mentioned animals were weighed, measured and dissected. Thymic slices were stained with eosin orange for detection of microanatomical details and with Bodian's method for identification of the whole nerve fibres. Thymic MCs were stained with Astrablau. Histofluorescence microscopy was used for staining of adrenergic nerve fibres. Finally, all morphological results were submitted to the QAIs and statistical analysis of data. Our results suggest that after surgical sympathectomy, the greater part of adrenergic nerve fibres disappear while related MCs appear to show less evident fluorescence and few granules. On the contrary, electrostimulation of the cervical superior ganglion induced an increase in the fluorescence of adrenergic nerve fibres and of related MCs.

Nonpharmacological treatments for anxiety disorders

2002-01-01

An evidence-based review of nonpharmacological treatments for anxiety disorders is presented. The vast majority of the controlled research is devoted to cognitive behavior therapy (CBT) and shows its efficiency and effectiveness in all the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) anxiety disorders in meta-analyses. Relaxation, psychoanalytic therapies, Rogerian nondirective therapy, hypnotherapy and supportive therapy were examined in a few controlled studies, which preclude any definite conclusion about their effectiveness in specific phobias, agoraphobia, panic disorder, obsessive-compulsive disorder (OCD), and posttraumatic stress disorder (PTSD), CBT was clearly better than psychoanalytic therapy in generalized anxiety disorder (GAD) and performance anxiety Psychological debriefing for PTSD appeared detrimental to the patients in one high-quality meta-analysis. Uncontrolled studies of psychosurgery techniques for intractable OCD demonstrated a limited success and detrimental side effects. The same was true for sympathectomy in ereutophobia. Transcranial neurostimulation for OCD is under preliminary study. The theoretical and practical problems of CBT dissemination are discussed. PMID:22034140

Sympathetic neural control of indoleamine metabolism in the rat pineal gland

Lynch, H. J.; Hsuan, M.; Wurtman, R. J.

1975-01-01

The mechanisms responsible for the acceleration in rat pineal biosynthetic activity in response to prolonged exposure to darkness or to immobilization were investigated in animals whose pineals were surgically denervated. Some animals were adrenalectomized to remove one potential source of circulating catecholamines, and some were subjected to a partial chemical sympathectomy accomplished by a series of intravenous injections of 6-hydroxydopamine. Results suggest that N-acetyltransferase (NAT) activity can be enhanced either by release of norepinephrine from sympathetic terminals within the pineal or from sympathetic nerve terminals elsewhere. The stress of immobilization stimulates the pineal by increasing circulating catecholamines. Photic control of pineal function requires intact pineal sympathetic innervation, since the onset of darkness apparently does not cause a sufficient rise in circulating catecholamines to stimulate the pineal. The present studies suggest that nonspecific stress triggers increased biosynthesis and secretion of melatonin; it is possible that this hormone may participate in mechanisms of adaptation.

Computed tomographic anatomy of the equine foot.

Claerhoudt, S; Bergman, E H J; Saunders, J H

2014-10-01

This study describes a detailed computed tomographic reference of the normal equine foot. Ten forefeet of five adult cadavers, without evidence of orthopaedic disease, were used. Computed tomography (CT) was performed on all feet. Two-millimetre thick transverse slices were obtained, and sagittal and dorsal planes were reformatted. The CT images were matched with the corresponding anatomic slices. The phalanges and the distal sesamoid bone showed excellent detail. The extensor and flexor tendons (including their attachments) could be clearly evaluated. The collateral (sesamoidean) ligaments could be readily located, but were difficult to delineate at their proximal attachment. The distal digital annular ligament could only be distinguished from the deep digital flexor tendon proximal to the distal sesamoid bone, and its proximal attachment could be identified, but not its distal insertion. Small ligaments (impar ligament, chondrosesamoidean, chondrocoronal and chondrocompedal ligaments, axial and abaxial palmar ligaments of the proximal inter-phalangeal joint) were seen with difficulty and not at all slices. The joint capsules could not be delineated from the surrounding soft tissue structures. The lateral and medial proprius palmar digital artery and vein could be visualized occasionally on some slices. The ungular cartilages, corium and hoof wall layering were seen. The nerves, the articular and fibrocartilage of the distal sesamoid bone and the chondroungular ligament could not be assessed. Computed tomography of the equine foot can be of great value when results of radiography and ultrasonography are inconclusive. Images obtained in this study may serve as reference for CT of the equine foot. © 2013 Blackwell Verlag GmbH.

Innervation of the wrist joint and surgical perspectives of denervation.

Van de Pol, Gerrit J; Koudstaal, Maarten J; Schuurman, Arnold H; Bleys, Ronald L A W

2006-01-01

Because our experience with the techniques used in denervation surgery of the wrist joint often has proven insufficient in treating chronic pain we conducted an anatomic study to clarify the exact contributions of the nerves supplying the wrist joint. Our goal was to reveal all periosteal and capsular nerve connections and if necessary adjust our technique used in denervation surgery. Innervation of the wrist joint was investigated by microdissection and histologic examination of 18 human wrists. An acetylcholinesterase method was used to identify the nerves, both in whole-mount preparations and in sections. We found that the main innervation to the wrist capsule and periosteal nerve network came from the anterior interosseous nerve, lateral antebrachial cutaneous nerve, and posterior interosseous nerve. The palmar cutaneous branch of the median nerve, the deep branch of the ulnar nerve, the superficial branch of the radial nerve, and the dorsal branch of the ulnar nerve also were found to have connections with the capsule. The periosteal nerve branches did not appear to play a major role in the innervation of the capsule and ligaments; here the specific articular nerve branches proved more important. The posterior and medial antebrachial cutaneous nerves did not connect to the wrist capsule or periosteum but rather terminated in the extensor and flexor retinaculum. Based on our findings we propose to denervate the wrist by making 2 incisions. With one palmar and one dorsal incision it should be possible to disconnect the periosteum from the capsule and interrupt the majority of the capsular nerve branches.

Site-specific adaptive remodeling of Greyhound metacarpal cortical bone subjected to asymmetrical cyclic loading.

2001-05-01

To quantify geometric, inertial, and histomorphometric properties at the mid-diaphyseal level of left and right metacarpal bones (MCB) of racing Greyhounds. MCB from 7 racing Greyhounds euthanatized for reasons unrelated to MCB abnormalities. Mid-diaphyseal transverse sections of left and right MCB were stained with H&E or microradiographed. Images of stained sections were digitized, and cross-sectional area, cortical area, and maximum and minimum area moments of inertia of each bone were determined. Histomorphometric data (osteonal density, osteonal birefringence, and endosteal new lamellar bone thickness) were collected in 4 quadrants (dorsal, palmar, lateral, medial). Values were compared between limbs and among bones and quadrants. Cross-sectional area, cortical area, and maximum and minimum moments of inertia of left MCB-IV and -V were significantly greater, compared with contralateral bones. Overall osteonal densities in the dorsal quadrants of left MCB were greater, compared with lateral and medial quadrants. Also, percentage of birefringent osteons was significantly greater in the dorsal quadrant of left MCB-III, -IV, and -V, compared with the palmar quadrant. Thickness of new endosteal lamellar bone was not significantly influenced by limb, bone, or quadrant. Increased cortical thickness and geometric properties of left MCB-IV and -V of Greyhounds, together with altered turnover and orientation of osteons in the dorsal quadrants of left MCB, are site-specific adaptive responses associated with asymmetric cyclic loading as a result of racing on circular tracks. Site-specific adaptive remodeling may be important in the etiopathogenesis of fatigue fractures in racing Greyhounds.

Biomechanics of phalangeal curvature.

PubMed

Richmond, Brian G

2007-12-01

Phalangeal curvature has been widely cited in primate functional morphology and is one of the key traits in the ongoing debate about whether the locomotion of early hominins included a significant degree of arboreality. This study examines the biomechanics of phalangeal curvature using data on hand posture, muscle recruitment, and anatomical moment arms to develop a finite element (FE) model of a siamang manual proximal phalanx during suspensory grasping. Strain patterns from experiments on intact cadaver forelimbs validated the model. The strain distribution in the curved siamang phalanx FE model was compared to that in a mathematically straight rendition in order to test the hypotheses that curvature: 1) reduces strain and 2) results in lower bending strains but relatively higher compression. In the suspensory posture, joint reaction forces load the articular ends of the phalanx in compression and dorsally, while muscle forces acting through the flexor sheath pull the mid-shaft palmarly. These forces compress the phalanx dorsally and tense it palmarly, effectively bending it 'open.' Strains in the curved model were roughly half that of the straight model despite equivalent lengths, areas, mechanical properties, and loading conditions in the two models. The curved model also experienced a higher ratio of compressive to tensile strains. Curvature reduces strains during grasping hand postures because the curved bone is more closely aligned with the joint reaction forces. Therefore, phalangeal curvature reduces the strains associated with arboreal, and especially suspensory, activity involving flexed digits. These results offer a biomechanical explanation for the observed association between phalangeal curvature and arboreality.

Dermatoglyphics in relation to brain volumes in twins concordant and discordant for bipolar disorder.

2014-12-01

Palmar and finger dermatoglyphics are formed between the 10th and the 17th weeks of gestation and their morphology can be influenced by genetic or environmental factors, interfering with normal intrauterine development. As both the skin and the brain develop from the same embryonal ectoderm, dermatoglyphic alterations may be informative for early abnormal neurodevelopmental processes in the brain. We investigated whether dermatoglyphic alterations are related to structural brain abnormalities in bipolar disorder and to what extent they are of a genetic and of an environmental origin. Dermatoglyphics and volumetric data from structural MRI were obtained in 53 twin pairs concordant or discordant for bipolar disorder and 51 healthy matched control twin pairs. Structural equation modeling was used. Bipolar disorder was significantly positively associated with palmar a-b ridge count (ABRC), indicating higher ABRC in bipolar patients (rph=.17 (CI .04-.30)). Common genes appear to be involved because the genetic correlation with ABRC was significant (rph-A=.21 (CI .05-.36). Irrespective of disease, ABRC showed a genetically mediated association with brain volume, indicated by a significant genetic correlation rph-A of respectively -.36 (CI -.52 to -.22) for total brain, -.34 (CI -.51 to -.16) total cortical volume, -.27 (CI -.43 to -.08) cortical gray matter and -.23 (CI -.41 to -.04) cortical white matter. In conclusion, a genetically determined abnormal development of the foetal ectoderm between the 10th and 15th week of gestation appears related to smaller brain volumes in (subjects at risk for) bipolar disorder.

Hunter, Barbara G; Semevolos, Stacy A

2013-07-01

A 2-year-old male Suri alpaca was referred for evaluation of severe right forelimb lameness of 2 weeks' duration following a traumatic episode. Examination of the distal aspect of the metacarpus revealed 4 wounds exuding purulent material. On weight bearing, the metacarpophalangeal joint was severely hyperextended with the palmar surface touching the ground. Ultrasonography of the palmar surface of the metacarpus revealed desmitis of the proximal suspensory ligament, a large core lesion of the deep digital flexor tendon at mid-metacarpus, and complete loss of fiber pattern within the deep digital flexor tendon and lateral aspect of the superficial digital flexor tendon distally. The alpaca was treated systemically with antimicrobials and anti-inflammatory drugs and underwent repeated antimicrobial intraosseous regional limb perfusion. A bandage and splint were applied to stabilize the affected forelimb in an anatomically correct position, and the alpaca underwent prolonged stall confinement. At the time of hospital discharge 5 days after initial evaluation, clinical evidence of infection at the wound sites was absent. Three months following treatment, the alpaca was moving freely in a small paddock and had moderate hyperextension of the metacarpophalangeal joint. Treatment of septic flexor tendonitis and suspensory desmitis with antimicrobial intraosseous regional limb perfusion in combination with systemic treatment with antimicrobials and orthopedic support resulted in an excellent outcome in this alpaca. Antimicrobial intraosseous regional limb perfusion is simple to perform and has the potential to be beneficial in the treatment of infections in the distal portion of a limb in camelids.

When interventions to the hand are aimed at improving function of specific fingers or the thumb, the RIHM (Rotterdam Intrinsic Hand Myometer) is a validated tool and offers more detailed information to assess strength of the involved joints besides grip and pinch measurements. In this study, strength was measured in 65 thumbs in 40 patients diagnosed with thumb hypoplasia. These 65 thumbs were classified according to Blauth. Longitudinal radial deficiencies were also classified. The strength measurements comprised of grip, tip, tripod and key pinch. Furthermore palmar abduction and opposition of the thumb as well as abduction of the index and little finger were measured with the RIHM. For all longitudinal radial deficiency patients, grip and pinch strength as well as palmar abduction and thumb opposition were significantly lower than reference values (P<0.001). However, strength in the index finger abduction and the little finger abduction was maintained or decreased to a lesser extent according to the degree of longitudinal radial deficiency. All strength values decreased with increasing Blauth-type. Blauth-type II hands (n=15) with flexor digitorum superficialis 4 opposition transfer including stabilization of the metacarpophalangeal joint showed a trend toward a higher opposition strength without reaching statistical significance (P=0.094),however compared to non-operated Blauth-type II hands (n=6) they showed a lower grip strength (P=0.019). The RIHM is comparable in accuracy to other strength dynamometers. Using the RIHM, we were able to illustrate strength patterns on finger-specific level, showing added value when evaluating outcome in patients with hand related problems. © 2013.

We aimed to compare two digital nerve block techniques in patients due to traumatic digital lacerations. This was a randomized-controlled study designed prospectively in the emergency department of a university-based training and research hospital. Randomization was achieved by sealed envelopes. Half of the patients were randomised to traditional (two-injection) digital nerve block technique while single-injection digital nerve block technique was applied to the other half. Score of pain due to anesthetic infiltration and suturing, onset time of total anesthesia, need for an additional rescue injection were the parameters evaluated with both groups. Epinephrin added lidocaine hydrochloride preparation was used for the anesthetic application. Visual analog scale was used for the evaluation of pain scores. Outcomes were compared by using Mann-Whitney U test and Student t-test. Fifty emergency department patients ≥18 years requiring digital nerve block were enrolled in the study. Mean age of the patients was 33 (min-max: 19-86) and 39 (78 %) were male. No statistically significant difference was found between the two groups in terms of our main parameters; anesthesia pain score, suturing pain score, onset time of total anesthesia and rescue injection need. Single injection volar digital nerve block technique is a suitable alternative for digital anesthesias in emergency departments.

An increased frequency of thyroid autoantibodies has been reported in patients with palmar and plantar pustulosis (PPP). This study was undertaken to determine the frequency and type of thyroid disease in 32 patients with this disease compared with a control group. Thyroid disease was demonstrated in 53% of the patients with PPP as compared to 16% in the matched control group. Fourteen patients with PPP had an enlarged thyroid and in six there were thyroid autoantibodies. There appears to be an increased incidence of goitre and thyroid autoantibodies in PPP with a decrease in the level of the thyroid hormones.

Congenital symmetrical weakness of the upper limbs resembling brachial plexus palsy: a possible sequel of drug toxicity in first trimester of pregnancy?

We report a 14-month-old girl with a symmetrical paralysis from birth, limited to the upper limbs and resembling a severe, complete bilateral brachial plexus palsy. The presence of dimples over the wrists, shoulders and scapulae and abnormal palmar dermatoglyphics suggested an early prenatal onset. Previous reports and the course of the disease in our case suggest this sporadic condition is not progressive. Although no definitive causative factor has been identified in previously reported cases, the affection in our case is possibly related to Debendox (Bendectin) and nitrofurantoin taken in early pregnancy for nausea and renal tract infection, respectively.

1999-10-01

We report two cases of high-pressure injection injuries to the fingertip in which free toe pulp flaps were used to resurface the palmar surface of the finger following extensive wound debridement. There was good return of sensibility and, because of the high durability of the donor skin, both patients regained good functional use of the injured digits and returned to heavy manual work. There was minimal associated morbidity of the donor sites. The free toe pulp flap represents an excellent alternative for resurfacing the digit with a large residual skin defect after high-pressure injection injury.

Microneedling: Advances and widening horizons

2016-01-01

Microneedling is a very simple, safe, effective, and minimally invasive therapeutic technique. It was initially introduced for skin rejuvenation, however, now it is being used for a very wide range of indications including acne scar, acne, post-traumatic/burn scar, alopecia, skin rejuvenation, drug delivery, hyperhidrosis, stretch marks, and many more. Moreover, during the last 10 years, many new innovations have been made to the initial instrument, which was used for microneedling. This technique can be combined with other surgical techniques to provide better results. In particular, it is a very safe technique for dark skin types, where risk of postinflammatory pigmentation is very high with other techniques that damage the epidermis. In this review article, we are updating on the different instruments now available for this procedure, and its efficacy when performed alone or in combination with other techniques for various indications.

Brin, Mitchell F

2009-10-01

Since the late 1970s, local injections of BoNT have provided clinical benefit for patients with inappropriately contracting muscles with or without pain or sensory disturbance. Marketing authorization for some BoNTs, depending on country, include core indications of dystonia (blepharospasm and cervical dystonia), large muscle spastic disorders (not yet approved in the United States, e.g., adult post-stroke spasticity and equinus foot deformity), hyperhidrosis and aesthetic. Subsequent development has extended to selected conditions characterized by recurrent or chronic pain (migraine headache), and urologic indications (neurogenic/idiopathic overactive bladder; prostate hyperplasia), with multiple additional opportunities available. Portfolio management requires a careful individual opportunity assessment of scientific and technical aspects (basic science foundation, potential to treat unmet medical need, product-specific risk in specific populations, therapeutic margin/safety profile, and probability of successful registration pathway). This article describes ongoing development targets for BOTOX.

Comparative study of 2 commissural dorsal flap techniques for the treatment of congenital syndactyly.

Many commissural reconstruction techniques have been described for the treatment of syndactyly. This study is the first to compare long-term results of 2 commissural dorsal flap procedures (T-flap and omega-flap). Fifty-nine web-spaces in 39 patients, operated on between 1991 and 2008, were retrospectively analyzed. Thirty-six T-flap and 23 omega-flap procedures were performed using full-thickness skin graft in every case for digital resurfacing. Factors that could affect the long-term outcome were collected, including development of web-creep, clinodactyly, and flexion contracture. Patients were reviewed with a mean follow-up of 5 years and 8 months. Preoperative complexity of syndactyly influenced the development of clinodactyly and flexion contracture. Among the patients who developed clinodactyly, 96% had surgery for complex syndactyly. No difference was found between the 2 flap methods concerning digital deformation and mobility. However, web-creep occurred more frequently after T-flap than after omega-flap procedures (17% vs. 5%). The combination of either dorsal commissural T-flaps or omega-flaps with full-thickness graft to resurface digits is a reliable technique for the treatment of syndactyly with satisfactory functional and cosmetic results. Long-term results are not influenced by the type of flap. Nevertheless, the omega-flap technique, using 2 triangular lateral-palmar flaps, avoids use of skin graft to cover lateral-palmar aspects of the new commissure, consequently reducing the incidence of web-creep. In cases of syndactyly, the primary prognostic factor is whether the patient has simple or complex syndactyly. In complex syndactyly, the risk of long-term unfavorable results is higher. When complex complicated syndactyly is involved, postoperative complication rates increase. Level III.

Efficacy of ketamine hydrochloride administered as a basilar sesamoid nerve block in alleviating foot pain in horses caused by natural disease.

A local anaesthetic agent capable of temporarily resolving lameness after being administered perineurally would be helpful because rapid return of lameness would allow for other analgesic techniques to be performed within a short period of time. To determine if a 3% solution of ketamine hydrochloride (HCl), administered around the palmar nerves at the level of the base of the proximal sesamoid bones, can improve naturally occurring lameness that can be improved or abolished with a basilar sesamoid nerve block performed using lidocaine HCl and to compare the change in gait produced using lidocaine to the change in gait produced using ketamine by using objective lameness assessment. Experimental trial using research horses with naturally occurring lameness. Seven horses, chronically lame on a thoracic limb, were chosen for the study. A wireless, inertial, sensor-based, motion analysis system was used to evaluate lameness before and after administration of 2% lidocaine and later, before and after administration of 3% ketamine over the palmar digital nerves at the base of the proximal sesamoid bones (a basilar sesamoid nerve block) at 5 min intervals for 30 min. Lameness scores obtained before and after administration of lidocaine and ketamine HCl were compared using repeated measures analysis. Gait significantly improved after basilar sesamoid nerve blocks using 2% lidocaine, but gait did not significantly improve after performing the same nerve block using 3% ketamine HCl. Ketamine (3%) administered perineurally for regional anaesthesia of the digit does not desensitise the digit to the same extent as does lidocaine and thus 3% ketamine appears to have no value as a local anaesthetic agent for diagnostic regional anaesthesia. © 2013 EVJ Ltd.

To compare skin-surface cooling caused by the application of an ice bag (15min) and the projection of carbon dioxide microcristals (2min) under high pressure (75 bar) and low temperature (-78 degrees C), a modality called hyperbaric gaseous cryotherapy. Randomized controlled trial with repeated measure. Laboratory experiment. Twelve healthy male subjects (mean +/- standard deviation, 22.9+/-1.8y). Ice bag and hyperbaric gaseous cryotherapy were randomly applied on the skin of the nondominant hand. Skin temperature of the cooled (dorsal and palmar sides) and contralateral (dorsal side) hands were continuously measured with thermistor surface-contact probes before, during, and after (30min) cooling. Hyperbaric gaseous cryotherapy projection induced a large decrease (P<.05) of the dorsal skin temperature of the cooled hand (from 32.5 degrees +/-0.5 degrees C to 7.3 degrees +/-0.8 degrees C) and a significant decrease of the skin temperature of the palmar side and of the contralateral hand. The skin temperature of the dorsal side of the cooled hand was decreased with an ice bag (from 32.5 degrees +/-0.6 degrees C to 13.9 degrees +/-0.7 degrees C, P<.05). However, the lowest temperature was significantly higher than during hyperbaric gaseous cryotherapy, and no significant changes in the other skin temperatures were observed. Rewarming was equal after the 2 modalities, highlighting a more rapid increase of the skin temperature after hyperbaric gaseous cryotherapy. Hyperbaric gaseous cryotherapy projection decreased the skin temperature of the cooled and contralateral hand, suggesting a systemic skin vasoconstriction response. On the other hand, the vascular responses triggered by ice pack cooling appeared limited and localized to the cooled area.

Background The scaphoid is critical for maintaining the stability and movement of the wrist joints. This study aimed to develop a new internal fixator absorbable scaphoid screw (ASS) for fixation of the scaphoid waist after fracture and to test the biomechanical characteristics of ASS. Materials and methods An ASS was prepared using polylactic acids and designed based on scaphoid measurements and anatomic features. Twenty fractured scaphoid waist specimens were randomly divided into experimental and control groups (n=10/group). Reduction and internal fixation of the scaphoid were achieved with either Kirschner wires (K-wires) or ASS. A moving target simulator was used to test palmar flexion and dorsal extension, with the range of testing (waist movement) set from 5° of palmar flexion to 25° of dorsal extension. Flexion and extension were repeated 2,000 times for each specimen. Fracture gap displacements were measured with a computerized tomography scanning. Scaphoid tensile and bending strengths were measured by using a hydraulic pressure biomechanical system. Results Prior to biomechanical fatigue testing, fracture gap displacements were 0.16±0.02 mm and 0.22±0.02 mm in the ASS and K-wire groups, respectively. After fatigue testing, fracture gap displacements in the ASS and the K-wire groups were 0.21±0.03 mm and 1.52±0.07 mm, respectively. The tensile strengths for the ASS and K-wire groups were 0.95±0.02 MPa and 0.63±0.02 MPa, respectively. Conclusion Fixation using an ASS provided sufficient mechanical support for the scaphoid after fracture. PMID:27217756

Upper extremity musculoskeletal disorders represent an important health issue across all industry sectors; as such, the need exists to develop models of the hand that provide comprehensive biomechanics during occupational tasks. Previous optical motion capture studies used a single marker on the dorsal aspect of finger joints, allowing calculation of one and two degree-of-freedom (DOF) joint angles; additional algorithms were needed to define joint centers and the palmar surface of fingers. We developed a 6DOF model (6DHand) to obtain unconstrained kinematics of finger segments, modeled as frusta of right circular cones that approximate the palmar surface. To evaluate kinematic performance, twenty subjects gripped a cylindrical handle as a surrogate for a powered hand tool. We hypothesized that accessory motions (metacarpophalangeal pronation/supination; proximal and distal interphalangeal radial/ulnar deviation and pronation/supination; all joint translations) would be small (less than 5° rotations, less than 2mm translations) if segment anatomical reference frames were aligned correctly, and skin movement artifacts were negligible. For the gripping task, 93 of 112 accessory motions were small by our definition, suggesting this 6DOF approach appropriately models joints of the fingers. Metacarpophalangeal supination was larger than expected (approximately 10°), and may be adjusted through local reference frame optimization procedures previously developed for knee kinematics in gait analysis. Proximal translations at the metacarpophalangeal joints (approximately 10mm) were explained by skin movement across the metacarpals, but would not corrupt inverse dynamics calculated for the phalanges. We assessed performance in this study; a more rigorous validation would likely require medical imaging. Published by Elsevier Ltd.

Hypothenar hammer syndrome from ice hockey stick-handling.

Zayed, Mohamed A; McDonald, Joey; Tittley, Jacques G

2013-11-01

Ulnar artery thrombosis and hypothenar hammer syndrome are rare vascular complications that could potentially occur with repeated blows or trauma to the hand. Although initially reported as an occupational hazard among laborers and craftsmen, it has been observed more recently among recreationalists and athletes. Until now, it has never been reported as a complication in ice hockey players. In this case report, a 26-year-old Canadian professional ice hockey player presented with acute dominant right hand paleness, coolness, and pain with hand use. The patient used a wooden hockey stick with a large knob of tape at the end of the handle, which he regularly gripped in the palm of his right hand to help with face-offs and general stick-handling. Sonographic evaluation demonstrated no arterial flow in the distal right ulnar artery distribution, and ulnar artery occlusion with no aneurysmal degeneration was confirmed by magnetic resonance angiogram. Intraarterial thrombolytic therapy was initiated, and subsequent serial angiograms demonstrated significant improvement in distal ulnar artery flow as well as recanalization of right hand deep palmar arch and digital arteries. The patient's symptoms resolved, and he was maintained on therapeutic anticoagulation for 3 months prior to returning to playing ice hockey professionally, but with a padded glove and no tape knob at the handle tip. This case highlights a unique presentation of hockey stick-handling causing ulnar artery thrombosis that was likely from repeated palmar hypothenar trauma. Appropriate diagnostic imaging, early intraarterial thrombolysis, and postoperative surveillance and follow-up were crucial for the successful outcome in this patient. Copyright © 2013 Elsevier Inc.

BACKGROUND Catheter-based renal sympathetic denervation has been reported to be effective for treatment resistance hypertension in Australia and Europe. However, in the blinded SYMPLICITY HTN-3 trial, renal denervation did not achieve a significant decrease in blood pressure (BP) in comparison to sham controls. There have been various discussions on the factors that influenced this result. CASE REPORT Two men on antihypertensive therapy underwent unilateral radical nephroureterectomy for cancer of the renal pelvis. When the renal artery adventitia was stripped and cauterized just before renal artery ligation, the measured BP of the 2 men increased after stripping adventitia and decreased gradually after cauterization of the renal artery. This was presumably due to removal of renal artery sympathetic nerves, similar to the mechanism of catheter-based renal sympathetic denervation, although anesthesia, fluid infusion, and/or mesenteric traction may have had an influence. CONCLUSIONS A similar strategy involving thoracolumbar sympathectomy was reported about 50 years ago. The clinically significant blood pressure reduction in these patients suggests renal denervation is effective.

The Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an uncommon disorder caused by a mutation in Patched, tumor suppressor gene. It is mainly characterized by numerous early onset basal cell carcinomas, odontogenic cysts of jaw and skeletal abnormalities. Due to the wide clinical spectrum, treatment and management of its modalities are not standardized and should be individualized and monitored by a multidisciplinary team. We report a typical case in a 30-year-old man with multiple basal cell carcinomas, keratotic pits of palmar creases and bifid ribs, with a history of several corrective surgeries for keratocystic odontogenic tumors, among other lesions characteristic of the syndrome.

2008-01-01

Non-malignant fibrosing tumors in the pediatric hand or juvenile fibromatoses are clinically challenging because of their relatively infrequent occurrence and because of the variety of names associated with these diseases. We conducted a review of a personal case series of pediatric patients with these tumors and discuss here the more common histologic types and clinical characteristics of the disease spectrum in the context of the available published literature. All histologic samples were reviewed by a single pathologist. Infantile myofibromatosis, fibrous hamartoma of infancy, juvenile aponeurotic fibromatosis, palmar fibromatosis (Dupuytren’s type), infantile digital fibromatosis (Reye’s tumor), fibroma of the tendon sheath, and melorheostosis represent the encountered lesions.

The treatment of progressive Dupuytren contractures has historically been and continues to be largely surgical. Although a number of surgical interventions do exist, limited palmar fasciectomy continues to be the most common and widely accepted treatment option. Until recently, nonsurgical options were limited and clinically ineffective. However, the commercial availability and recent approval of collagenase clostridium histolyticum now provides practitioners with a nonsurgical approach to this disease. This article presents a comprehensive review of the surgical and nonsurgical treatments of Dupuytren disease, with a focus on collagenase. Copyright © 2011 American Society for Surgery of the Hand.

Peterson, Steven L; Gordon, Michael J

2004-09-01

We report a patient with previous wrist trauma and development of a symptomatic neuroma of the palmar cutaneous branch of the median nerve. The patient had previously been successfully treated with lateral arm free flap coverage with neurorrhaphy to a segment of the posteroantebrachial cutaneous nerve carried with the flap. Two years following this procedure the patient experienced re-onset of symptoms prompting surgical exploration of the area. At the time of operation a recurrent neuroma was found at the free distal terminus of the transferred posteroantebrachial cutaneous nerve. The neuroma was repositioned into the distal radius via a burr hole with relief of symptoms.

Dermatoglyphics in dermatitis herpetiformis.

Roberts, D F; Abdullah, N; Marks, J; Shuster, S

1978-12-01

In a dermatoglyphic study of 101 patients with dermatitis herpetiformis, comparison was made with their normal relatives and several random normal series. The results of the several comparisons are quite consistent, considering the nature of the data, for the all point to an attenuation of qualitative and quantitative digital and palmar traits in the patients. It is argued that these differences are associated with the disease itself, and that some of the female relatives have an inherited tendency to the disorder, but do not express it. The findings suggest the involvement of genetic factors in the aetiology, and possibly intrauterine environmental influences as well.

The dermatoglyphics of 54 leukemic children do not differ significantly from those of 25 mothers and 592 unrelated controls with respect to frequency of digital pattern types, position of axial triradius, or type of palmar flexion creases. These findings do not support the hypothesis that children with leukemia have an increased frequency of unusual dermal patterns, but suggest that the dermatoglyphics of leukemic children are not distinctive and therefore have no practical value in the diagnosis of childhood leukemia. Whatever factors are responsible for the development of leukemia in children, these factors do not appear regularly to affect the differentiation of the dermal ridges. PMID:5112119

The authors reviewed the outpatient charts diagnosed as hyperthyroidism at Srinagarind Hospital from June 1998-June 2004. The objective was to compare the clinical features of hyperthyroidism in patients older and younger than 60 years old. There were 922 cases enrolled, 84 cases (9.11%) were 60 years old and above. The female: male ratio was 3.4:1 and 4:1 and the mean ages were 64.2 +/- 3.7 and 37.4 +/- 11.2 years old in the elder and younger group, respectively. The common presentations were dyspnea (94.1, 96.5%), weight loss (93.8, 87.9%) and palpitation (83.3, 93.1%) in the elder and younger, respectively. The more significant clinical presentations in the elder group were atrial fibrillation, weakness and anorexia whereas exophthalmos, goiter, heat intolerance and hyperhidrosis were not as frequent. Thus, the classic presentations often lacked in the elder group. Therefore, unexplained AF, weakness and anorexia should not exclude hyperthyroidism even with paucity of typical clinical features.

The excess salt appetite of humans is not due to sodium loss in adulthood.

PubMed

Leshem, Micah

2009-09-07

In seeking the determinants of high salt intake, studies in rat have shown that sodium depletion in utero, neonatally, or in maturity, permanently enhances salt appetite. In humans too, salt appetite is permanently enhanced after perinatal sodium loss, but it is not known if sodium loss in adults also enhances salt intake. If it does, it might contribute to high sodium intake and its associated pathologies. Therefore, using methods that revealed the perinatal determinants of sodium appetite, here we evaluated whether salt appetite is enhanced in adults with a varied history of sodium loss. We find that putative sodium loss due to hyperhidrosis, hemorrhage, dehydration, or breastfeeding, does not increase salt appetite significantly. The findings contrast with the many studies showing enduring enhancement of salt appetite by perinatal sodium loss in humans, and suggest that lifelong salt appetite is established very early in development. In turn this counsels very early intervention to prevent lifelong excess sodium intake.

Sweating is variably altered by physical exercise, diabetic neuropathy and antiperspirants. Skin temperature, skin surface water loss (SSWL), the Corneometer(®) average capacitance (CMAC) and skin capacitance mapping (SCM) were measured before and after moderate physical exercise in 20 healthy subjects. The effect of 5% aluminium chloride hexahydrate (ACH) in a water solution was similarly tested. The same assessments were performed in 20 diabetic patients at rest. Diabetic neuropathy appeared at rest as an increased (compensatory) SCM on the forearms without obvious modification on the hypohidrotic legs. On ACH sites after exercise, SCM revealed both a lowered number of active sweat glands and a lighter stratum corneum (SC) (dryness). In addition, CMAC and SSWL were decreased on ACH sites at rest and at completion of exercise. In diabetic neuropathy, the compensatory hyperhidrosis is more easily disclosed than the hypohidrosis. ACH affects both sweat excretion and the SC hydration. © 2011 John Wiley & Sons A/S.

Introduction: Dermatoglyphics is a collective term for all the integumentary features (skin patterning of the fingers, toes, palms and soles) and it applies to the division of the anatomy which embraces their study. Aims and Objectives: The purpose of this study was to examine the predominant finger tip patterns in the patients of carcinoma breast. An attempt is also being made to devise a score to assess the risk variables. Materials and Methods: The fingerprints of 100 carcinoma breast patients were obtained and they were compared with those of 100 females who were not suffering from any malignancy till date. The different quantitative parameters of each hand of both the cancer patients and the controls were studied. The parameters which were included were the fingertip ridge pattern, the ridge count in the individual fingers, the Total Finger Ridge Count (TFRC) and the Absolute Finger Ridge Count (AFRC). Results: There was a significant increase in the arch pattern and a decrease in the radial loops in the right thumb (p<0.001), the left thumb (p<0.001), the left index finger (p<0.001) and the left middle finger (p<0.001). A comparison of all the five fingers of both the left and right hands of the cancer patients with the controls showed an arch pattern (p<0.001) with the highest frequency. The lower values of the TFRC (below 50) were associated with carcinoma breast .The lower values of the AFRC (below 100) were associated with the cancer patients. Conclusion: This study was able to establish a specific finger tip predominance in the Carcinoma breast patients. PMID:23730629

Genome-Wide Analysis Using Exon Arrays Demonstrates an Important Role for Expression of Extra-Cellular Matrix, Fibrotic Control and Tissue Remodelling Genes in Dupuytren's Disease

Dupuytren's disease (DD) is a classic example of pathological fibrosis which results in a debilitating disorder affecting a large sector of the human population. It is characterized by excessive local proliferation of fibroblasts and over-production of collagen and other components of extracellular matrix (ECM) in the palmar fascia. The fibrosis progressively results in contracture of elements between the palmar fascia and skin causing flexion deformity or clawing of the fingers and a severe reduction in hand function. While much is known about the pathogenesis and surgical treatment of DD, little is known about the factors that cause its onset and progression, despite many years of research. Gene expression patterns in DD patients now offers the potential to identify genes that direct the pathogenesis of DD. In this study we used primary cultures of fibroblasts derived from excisional biopsies of fibrotic tissue from DD patients to compare the gene expression profiles on a genome-wide basis with normal control fibroblasts. Our investigations have identified genes that may be involved with DD pathogenesis including some which are directly relevant to fibrosis. In particular, these include significantly reduced expression levels of three matrix metallopeptidases (MMP1, MMP3, MMP16), follistatin, and STAT1, and significantly increased expression levels of fibroblast growth factors (FGF9, FGF11), a number of collagen genes and other ECM genes in DD patient samples. Many of these gene products are known to be involved in fibrosis, tumour formation and in the normal processes of tissue remodelling. In addition, alternative splicing was identified in some DD associated genes. These highly sensitive genomic investigations provide new insight into the molecular mechanisms that may underpin the development and progression of DD. PMID:23554969

The ability of short-duration high-intensity exercise to stimulate bone formation in confinement was investigated using immature Holstein bull calves as a model. Eighteen bull calves, 8 wk of age, were assigned to one of three treatment groups: 1) group-housed (GR, which served as a control), 2) confined with no exercise (CF), or 3) confined with exercise (EX). The exercise protocol consisted of running 50 m on a concrete surface once daily, 5 d/wk. Confined calves remained stalled for the 42-d duration of the trial. Blood samples were taken to analyze concentrations of osteocalcin and deoxypyridinoline, markers of bone formation and resorption. At the completion of the trial, calves were humanely killed, and both forelegs were collected. The fused third and fourth metacarpal bone was scanned using computed tomography for determination of cross-sectional geometry and bone mineral density. Three-point bending tests to failure were performed on metacarpal bones. The exercise protocol resulted in the formation of a rounder bone in EX as well as in increased dorsal cortex thickness compared with those in the GR and CF. The exercised calves had a significantly smaller medullary cavity than CF and GR (P < 0.01) and a larger percentage of cortical bone area than CF (P < 0.01). Dorsal, palmar, and total bone mineral density was greater in EX than in CF (P < 0.05), and palmar and total bone mineral densities were greater (P < 0.05) in EX than in GR. There was a trend for the bones of EX to have a higher fracture force than CF (P < 0.10). Osteocalcin concentrations normalized from d 0 were higher in EX than CF (P < 0.05). Therefore, the exercise protocol altered bone shape and seemed to increase bone formation comparison with the stalled and group-housed calves.

Anaemia is highly prevalent in children of developing countries. It is associated with impaired physical growth and mental development. Palmar pallor is recommended at primary level for diagnosing it, on the basis of few studies. The objective of the study was to systematically assess the accuracy of clinical signs in the diagnosis of anaemia in children. A systematic review on the accuracy of clinical signs of anaemia in children. We performed an Internet search in various databases and an additional reference tracking. Studies had to be on performance of clinical signs in the diagnosis of anaemia, using haemoglobin as the gold standard. We calculated pooled diagnostic likelihood ratios (LR's) and odds ratios (DOR's) for each clinical sign at different haemoglobin thresholds. Eleven articles met the inclusion criteria. Most studies were performed in Africa, in children underfive. Chi-square test for proportions and Cochran Q for DOR's and for LR's showed heterogeneity. Type of observer and haemoglobin technique influenced the results. Pooling was done using the random effects model. Pooled DOR at haemoglobin <11 g/dL was 4.3 (95% CI 2.6-7.2) for palmar pallor, 3.7 (2.3-5.9) for conjunctival pallor, and 3.4 (1.8-6.3) for nailbed pallor. DOR's and LR's were slightly better for nailbed pallor at all other haemoglobin thresholds. The accuracy did not vary substantially after excluding outliers. This meta-analysis did not document a highly accurate clinical sign of anaemia. In view of poor performance of clinical signs, universal iron supplementation may be an adequate control strategy in high prevalence areas. Further well-designed studies are needed in settings other than Africa. They should assess inter-observer variation, performance of combined clinical signs, phenotypic differences, and different degrees of anaemia.

It is thought that local ischemia and oxygen radicals are responsible for fibroblast-to-myofibroblast cell transformation and proliferation. We hypothesized that hypoxia could differentially activate the contractility of fibroblasts from normal human palmar fascia and from fibroblasts-myofibroblasts of Dupuytren cords. Normal palmar fascia from 5 patients with carpal tunnel syndrome and Dupuytren cords from 5 patients were harvested. Cells were cultured from all tissue samples, and collagen lattices were prepared containing these cells. Oxygen treatment subgroups were created and incubated under hypoxic (1% O(2), 5% CO(2), and 94% N(2)), normoxic (21% O(2), 5% CO(2), and 74% N(2)), and hyperoxic (100% oxygen using 2.4 atm pressure twice a day for 7 d) conditions. After 7 days, each subgroup was photographed, and lattices were released from dishes. Postrelease photographs were taken immediately, 5 minutes after release, and after 1 hour. Areas of the lattices at each time point were calculated using MetaMorph software. Actin staining and live/dead cell analysis was performed. Linear repeated measures analysis of variance was used for data analysis given that contraction levels were measured over 3 distinct time points. We found a statistically significant difference between normal samples and Dupuytren samples in mean contraction levels over time. There was no statistically significant difference between tissue groups over the 3 time periods based on the oxygen treatment received. Our results showed a greater degree of contractility in Dupuytren disease cells than normal fibroblasts. However, the contraction in either group was not affected by oxygen level. Future in vivo research is needed to better understand the nature of pathophysiology of Dupuytren disease. Copyright © 2013 American Society for Surgery of the Hand. Published by Elsevier Inc.

[The reconstruction of the human body length from the wrist size].

2015-01-01

The objective of the present study was to develop the regression models for the reconstruction of the human body length from the wrist size taking into consideration the availability of the results of the measurements of the palm fragments or the wrist undergoing muscular contracture. The study included 106 Caucasoid subjects (41 men and 65 women) at the age varying from 18 to 76 years. The following parameters were measured: body length, wrist length, the length of the fingers and phalanges on the back of the hand, palmar length and width, ulnar edge size of the palm. It was shown that the selected longitudinal dimensions of the palm and fingers can be used to estimate the body length as accurately as from the wrist length. The high prognostic value of ulnar edge size of the palm was documented which allows this characteristic to be used in the cases of partial palm destruction or in the wrist with pronounced flexion contracture of the fingers. The most exact equations are those derived from the combination of the results of the measurement of the fingers and the ulnar edge size of the palm. Less accurate equations are based on the palmar dimensions alone and on the total wrist size with the exception of the equation for the wrist length with regard to the subject's sex. The gender information needs to be taken into account if the wrist is preserved to the extent that only the length of the palm and of the IV and V fingers can be measured or if the wrist is sufficiently long and wide (short and wide) and the gender is supposed to be masculine. In contrast, this information should be disregarded if the wrist is long and narrow (short and narrow) and the gender is supposedly feminine.

IGF-II and IGFBP-6 regulate cellular contractility and proliferation in Dupuytren's disease.

Dupuytren's disease (DD) is a common and heritable fibrosis of the palmar fascia that typically manifests as permanent finger contractures. The molecular interactions that induce the development of hyper-contractile fibroblasts, or myofibroblasts, in DD are poorly understood. We have identified IGF2 and IGFBP6, encoding insulin-like growth factor (IGF)-II and IGF binding protein (IGFBP)-6 respectively, as reciprocally dysregulated genes and proteins in primary cells derived from contracture tissues (DD cells). Recombinant IGFBP-6 inhibited the proliferation of DD cells, patient-matched control (PF) cells and normal palmar fascia (CT) cells. Co-treatments with IGF-II, a high affinity IGFBP-6 ligand, were unable to rescue these effects. A non-IGF-II binding analog of IGFBP-6 also inhibited cellular proliferation, implicating IGF-II-independent roles for IGFBP-6 in this process. IGF-II enhanced the proliferation of CT cells, but not DD or PF cells, and significantly enhanced DD and PF cell contractility in stressed collagen lattices. While IGFBP-6 treatment did not affect cellular contractility, it abrogated the IGF-II-induced contractility of DD and PF cells in stressed collagen lattices. IGF-II also significantly increased the contraction of DD cells in relaxed lattices, however this effect was not evident in relaxed collagen lattices containing PF cells. The disparate effects of IGF-II on DD and PF cells in relaxed and stressed contraction models suggest that IGF-II can enhance lattice contractility through more than one mechanism. This is the first report to implicate IGFBP-6 as a suppressor of cellular proliferation and IGF-II as an inducer of cellular contractility in this connective tissue disease.

Nevoid basal cell carcinoma syndrome (NBCC; Gorlin syndrome), an autosomal dominant disorder linked to 9q22.3-q31, and caused by mutations in PTC, the human homologue of the Drosophila patched gene, comprises multiple basal cell carcinomas, keratocysts of the jaw, palmar/plantar pits, spine and rib anomalies and calcification of the falx cerebri. We reviewed the findings on 105 affected individuals examined at the NIH since 1985. The data included 48 males and 57 females ranging in age from 4 months to 87 years. Eighty percent of whites (71/90) and 38% (5/13) of African-Americans had at least one basal cell carcinoma (BCC), withmore » the first tumor occurring at a mean age of 23 (median 20) years and 21 (median 20) years, respectively. Excluding individuals exposed to radiation therapy, the number of BCCs ranged from 1 to >1,000 (median 8) and 1 to 3 (median 2), respectively, in the 2 groups. Jaw cysts occurred in 78/105 (74%) with the first tumor occurring in 80% by the age of 20 years. The number of total jaw cysts ranged from 1 to 28 (median 3). Palmar pits and plantar pits were seen in 87%. Ovarian fibromas were diagnosed by ultrasound in 9/52 (17%) at a mean age of 30 years. Medulloblastoma occurred in 4 patients at a mean age of 2.3 years. Three patients had cleft lip or palate. Physical findings include {open_quotes}coarse face{close_quotes} in 54%, relative macrocephaly in 50%, hypertelorism in 42%, frontal bossing in 27%, pectus deformity in 13%, and Sprengel deformity in 11%.

Vascular hand-arm vibration syndrome--magnetic resonance angiography.

PubMed

Poole, C J M; Cleveland, T J

2016-01-01

The diagnosis of vascular hand-arm vibration syndrome (HAVS) requires consistent symptoms, photographic evidence of digital blanching and sufficient exposure to hand-transmitted vibration (HTV; A(8) > 2.5 m/s2). There is no reliable quantitative investigation for distinguishing HAVS from other causes of Raynaud's phenomenon and from normal individuals. Hypothenar and thenar hammer syndromes produce similar symptoms to HAVS but are difficult to diagnose clinically and may be confused with HAVS. Magnetic resonance angiography (MRA) is a safe and minimally invasive method of visualizing blood vessels. Three cases of vascular HAVS are described in which MRA revealed occlusions of the ulnar, radial and superficial palmar arteries. It is proposed that HTV was the cause of these occlusions, rather than blows to the hand unrelated to vibration, the assumed mechanism for the hammer syndromes. All three cases were advised not to expose their hands to HTV despite one of them being at Stockholm vascular stage 2 (early). MRA should be the investigation of choice for stage 2 vascular HAVS or vascular HAVS with unusual features or for a suspected hammer syndrome. The technique is however technically challenging and best done in specialist centres in collaboration with an occupational physician familiar with the examination of HAVS cases. Staging for HAVS should be developed to include anatomical arterial abnormalities as well as symptoms and signs of blanching. Workers with only one artery supplying a hand, or with only one palmar arch, may be at increased risk of progression and therefore should not be exposed to HTV irrespective of their Stockholm stage. © The Author 2015.

The status of dermatoglyphics as a biomarker of Tel Hashomer camptodactyly syndrome: a review of the literature.

PubMed

Wijerathne, Buddhika T B; Meier, Robert J; Agampodi, Suneth B

2016-09-20

Tel Hashomer camptodactyly syndrome is a rare disease and only a few cases have been reported. Dermatoglyphics potentially provide relevant phenotypic biomarkers that were initially noted as a vital clinical feature of this disease. Dermatoglyphics possibly can indicate growth disturbances that took place during early fetal development at the time when epidermal ridges were being formed into discernable patterns. Consequently, these intrauterine effects might well have occurred in association with the expression of the Tel Hashomer camptodactyly syndrome. Therefore, this review was undertaken to provide, as far as we know, the first attempt to broadly assess dermatoglyphic features that are connected with the Tel Hashomer camptodactyly syndrome. If a developmental association between dermatoglyphics and Tel Hashomer camptodactyly can be firmly established, this would probably document that Tel Hashomer camptodactyly disease has its origins during the early fetal period. A systematic literature search was conducted using articles from PubMed (Medline), POPLINE, Trip Database, Cochrane Library, and gray literature up to 31 March 2015. The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Fourteen relevant publications were included in the review. There were 23 cases of patients with Tel Hashomer camptodactyly syndrome that were described in these published articles. We reviewed the dermatoglyphics of 21 available cases out of all of the published and electronically available cases of Tel Hashomer camptodactyly. Eight cases reported whorls to be the most common digital pattern with an expected rise of ridge count. Two cases show significantly high frequencies of arch patterns. Further, there were increased numbers of palmar creases, along with abnormal flexion creases or other palmar dermatoglyphic abnormalities reported in all cases. This review highlighted the desirability of thoroughly observing and

Gorlin syndrome is a rare autosomal dominant disorder exhibiting high penetrance and variable expressivity. It is characterized by facial dysmorphism, skeletal anomalies, multiple basal cell carcinomas, odontogenic keratocysts (OKC), palmar and plantar pits, bifid ribs, vertebral anomalies and a variety of other malformations. Various neoplasms, such as medulloblastomas, meningiomas, ovarian and cardiac fibromas are also found in this syndrome. To describe a twelve-year-old patient with Gorlin-Goltz syndrome, with basal cell carcinomas and promyelocytic leukemia developed after receiving craniospinal radiation for a medulloblastoma. Bifid ribs as well as mandibular and maxillar OKC were also diagnosed Conclusion: The patient with Gorlin-Goltz syndrome should receive close follow-up for early detection of malformations nd malignant neoplasias.

Basal cell carcinoma (BCC), the most prevalent form of cancer worldwide, is a malignant skin neoplasm. It is locally invasive, with an exceptional incidence of reported metastasis. It can also be part of the Gorlin-Goltz syndrome, an autosomal dominant genetic disorder with high penetrance and variable expressivity, which is principally characterized by cutaneous BCC, odontogenic keratocysts, palmar and/or plantar pits, and falx cerebri calcification. We report the exceptional clinical observation of a 54-year-old man presenting bone metastasis from BCC in Gorlin-Goltz syndrome. Less than 300 cases of metastatic BCC have been reported in the literature. The present case is the second associated with Gorlin-Goltz syndrome. Copyright 2009 S. Karger AG, Basel.

Brazilian spotted fever is an acute febrile infectious disease caused by Rickettsia rickettsii, transmitted by tick bite. As this disease is rare and has high mortality rates in Brazil, the clinical aspects and epidemiological data may help the diagnosis. We report a case of Brazilian spotted fever in a 19-year-old patient who presented maculopapular exanthema in the palmar region and upper limbs, lymphadenopathy, fever, chills, headache, conjunctival hyperemia, nausea, vomiting, dyspnea, myalgia, developing neurological signs and abdominal pain. He was treated with doxycycline with clinical improvement. We emphasize the importance of the recognition of this disease by dermatologists as cutaneous manifestations are the key findings to establish early diagnosis and prevent complications.

The Bonete, Baygorria and Palmar dams of the Rio Negro successively submerged complex floodplain forests. The forest area submerged was greater than 280 km{sup 2} and resulted in large inputs of carbon, nitrogen and phosphorus to the reservoirs. After 46 years wood released 40, 34 and 71% of their original contents of carbon, nitrogen and phosphorus, respectively. During the same period the total amount of nutrients released by wood in comparison to leaves and litter is slightly less for nitrogen, almost double for phosphorus and more than three times for carbon. These results suggest that wood decomposition in water maymore » have a role in the trophic state of reservoirs.« less

1995-07-01

We compared the phenotypes, karyotypes, and molecular data for six cases of partial monosomy 21. Regions of chromosome 21, the deletion of which corresponds to particular features of monosomy 21, were thereby defined. Five such regions were identified for 21 features. Ten of the features could be assigned to the region flanked by genes APP and SOD1: six facial features, transverse palmar crease, arthrogryposis-like symptoms, hypertonia, and contribution to mental retardation. This region, covering the interface of bands 21q21-21q22.1, is 4.7-6.4 Mb long and contains the gene encoding the glutamate receptor subunit GluR5 (GRIK1). 82 refs., 5 figs., 1 tab.

Unusual pattern of the first dorsal metacarpal artery.

PubMed

Bianchi, Homero; Saravia, Diego; Ottone, Nicolas Ernesto

2017-07-01

This report describes an unusual pattern of the first dorsal metacarpal artery (FDMA) regarding its course and termination. This FDMA had an abnormal course, passing deep to various anatomical elements related to the index finger, with unusual termination in the radial and ulnar proper palmar digital arteries feeding the second and third fingers, respectively. There is no mention of this anatomical variation in the literature. We report the possible embryological origin of this case and other variations related to the FDMA. This unusual pattern represents a new reason to consider anatomical knowledge important for surgeons whose procedures are in this area and to ensure an accurate diagnosis and safe treatment of pathologies that might engage this anatomical variation.

Inherited congenital bilateral atresia of the external auditory canal, congenital bilateral vertical talus and increased interocular distance.

Six out of twenty descendants of a reportedly affected grandfather have congenital bilateral symmetrical and isolated subtotal atresia of the external auditory canal. Four of the six affected descendants have bilateral foot anomalies--two affected cousins having congenital vertical talus. All of the three affected boys in the third generation have increased interocular distance. Short fifth fingers, bilateral single transverse palmar creases, pyloric stenosis and congenital exotropia were found infrequently and are considered coincidental features. Apart from the atresia, oto-rhinolaryngologic examination, mental function, dermatoglyphics, IgA, kidney function and heart function of the affected descendants were all normal. The karyotype of four affected descendants examined was normal. An autosomal dominant inheritance with variable expressivity is suggested.

A 13-15/21 translocation chromosome in carrier father and mongol son.

PubMed

SERGOVICH, F R; SOLTAN, H C; CARR, D H

1962-10-20

Cytogenetic and dermatoglyphic features were studied in a family in which the mongoloid propositus inherited a 13-15/21 translocation chromosome from his father. Seven other healthy male carriers scattered throughout the pedigree produced nine chromosomally normal children and five carrier children in addition to the mongoloid propositus. These results show that carrier males do not necessarily produce an unusually large proportion of carrier children as previous reports would indicate. Dermatoglyphic studies showed that translocation carriers in this family have neither significantly more centralized nor less centralized palmar axial triradii than non-carrier relatives. No direct evidence was therefore found for the hypothesis that an allele is present on chromosome 21 which influences the height of the triradius.

Vagal modulation of high mobility group box-1 protein mediates electroacupuncture-induced cardioprotection in ischemia-reperfusion injury.

Excessive release of high mobility group box-1 (HMGB1) protein from ischemic cardiomyocytes activates inflammatory cascades and enhances myocardial injury after reperfusion. Here we report evidence that electroacupuncture of mice at Neiguan acupoints can inhibit the up-regulation of cardiac HMGB1 following myocardial ischemia and attenuate the associated inflammatory responses and myocardial injury during reperfusion. These benefits of electroacupuncture were partially reversed by administering recombinant HMGB1 to the mice, and further potentiated by administering anti-HMGB1 antibody. Electroacupuncture-induced inhibition of HMGB1 release was markedly reduced by unilateral vagotomy or administration of nicotinic receptor antagonist, but not by chemical sympathectomy. The cholinesterase inhibitor neostigmine mimicked the effects of electroacupuncture on HMGB1 release and myocardial ischemia reperfusion injury. Culture experiments with isolated neonatal cardiomyocytes showed that acetylcholine, but not noradrenaline, inhibited hypoxia-induced release of HMGB1 via a α7nAchR-dependent pathway. These results suggest that electroacupuncture acts via the vagal nerve and its nicotinic receptor-mediated signaling to inhibit HMGB1 release from ischemic cardiomyocytes. This helps attenuate pro-inflammatory responses and myocardial injury during reperfusion.

The influence of autonomic interventions on the sleep-wake-related changes in gastric myoelectrical activity in rats.

Significant changes in autonomic activity occur at sleep-wake transitions and constitute an ideal setting for investigating the modulatory role of the autonomic nervous system on gastric myoelectrical activity (GMA). Using continuous power spectral analysis of electroencephalogram, electromyogram, and electrogastromyogram (EGMG) data from freely moving rats that had undergone chemical sympathetomy and/or truncal vagotomy, sleep-wake-related fluctuations in GMA were compared among the intervention groups. The pattern and extent of fluctuations in EGMG power across the sleep-wake states was blunted most significantly in rats undergoing both chemical sympathectomy and truncal vagotomy. The effect of these interventions also varied with respect to the transition between different sleep-wake states. The most prominent influences were observed between active waking and quiet sleep and between paradoxical sleep and quiet sleep. The sleep-wake-related fluctuations in EGMG power are a result of joint contributions from both sympathetic and vagal innervation. Vagotomy mainly resulted in a reduction in EGMG power, while the role of sympathetic innervation was unveiled by vagotomy and this was reflected most obviously in the extent of the fluctuations in EGMG power. © 2011 Blackwell Publishing Ltd.

Renal Sympathetic Denervation: Hibernation or Resurrection?

PubMed

Papademetriou, Vasilios; Doumas, Michael; Tsioufis, Costas

The most current versions of renal sympathetic denervation have been invented as minimally invasive approaches for the management of drug-resistant hypertension. The anatomy, physiology and pathophysiology of renal sympathetic innervation provide a strong background supporting an important role of the renal nerves in the regulation of blood pressure (BP) and volume. In addition, historical data with surgical sympathectomy and experimental data with surgical renal denervation indicate a beneficial effect on BP levels. Early clinical studies with transcatheter radiofrequency ablation demonstrated impressive BP reduction, accompanied by beneficial effects in target organ damage and other disease conditions characterized by sympathetic overactivity. However, the failure of the SYMPLICITY 3 trial to meet its primary efficacy end point raised a lot of concerns and put the field of renal denervation into hibernation. This review aims to translate basic research into clinical practice by presenting the anatomical and physiological basis for renal sympathetic denervation, critically discussing the past and present knowledge in this field, where we stand now, and also speculating about the future of the intervention and potential directions for research. © 2016 S.

Studies on the trigeminal antidromic vasodilatation and plasma extravasation in the rat.

PubMed Central

Couture, R; Cuello, A C

1984-01-01

Antidromic stimulation of sensory peripheral branches of the trigeminal system (mental nerve) led to cutaneous vasodilatation and increased vascular permeability in rats anaesthetized with urethane. The antidromic vasodilatation observed in intact animals was not altered by decentralization or sympathectomy. Both antidromic vasodilatation and neurogenic plasma extravasation remained unaffected by pre-treatment with cimetidine, indomethacin, baclofen, guanethidine plus phentolamine and propranolol, but were significantly reduced by cimetidine plus mepyramine and atropine, suggesting that cholinergic and histaminergic components might be involved in the sensory neurogenic responses. Methysergide reduced only the extravasation, suggesting that probably serotonin liberated by mast cells upon sensory stimulation can contribute to the neurogenic responses. In tests using substance P (SP) antagonists (D-pro4, D- trp 7, 9, 10)-SP (4-11) and (D-pro2, D-trp 7, 9)-SP it was found that they are more active in reducing the neurogenic extravasation than the vasodilatation. In addition it was observed that (D-pro 4, D-trp 7, 9, 10)-SP (4-11) was the most potent substance P antagonist in reducing the plasma extravasation and antidromic vasodilatation resulting from sensory stimulation.

Background: Trichomycosis is asymptomatic bacterial infection of the axillary hairs caused by Corynebacterium sp. Objective: to bring a series of cases of trichomycosis, its clinical and microbiological experience. Materials and Methods: This report consists in a linear and observational retrospective study of 15 years of cases of trichomycosis confirmed clinically and microbiologically. Results: Fifty six confirmed cases of trichomycosis were included in this report. The majority were men 53/56 (94.6%), mean age was 32.5 years. The most commonly affected area was the axilla (92%), trichomycosis flava was the principal variant 55/56 (98.2%) and signs and symptoms associated were hyperhidrosis (87.5%), hairs’ texture change (57.1%) and odor (35.7%). Bacterial concretions were observed in all cases, and the predominant causative agent in 89.3% of all cases was Corynebacterium sp. Thirty patients were included in therapeutic portion of the study, and 28 (93.3%) of them experienced a clinical and microbiological cure. Conclusion: Trichomycosis is asymptomatic, superficial infection, which primarily affects axillary hairs. PMID:23960390

Umeclidinium (UMEC), a long‐acting muscarinic antagonist approved for chronic obstructive pulmonary disease (COPD), was investigated for primary hyperhidrosis as topical therapy. This study evaluated the pharmacokinetics, safety, and tolerability of a single dose of [14C]UMEC applied to either unoccluded axilla (UA), occluded axilla (OA), or occluded palm (OP) of healthy males. After 8 h the formulation was removed. [14C]UMEC plasma concentrations (Cp) were quantified by accelerator mass spectrometry. Occlusion increased systemic exposure by 3.8‐fold. Due to UMEC absorption‐limited pharmacokinetics, Cp data from the OA were combined with intravenous data from a phase I study. The data were described by a two‐compartment population model with sequential zero and first‐order absorption and linear elimination. Simulated systemic exposure following q.d. doses to axilla was similar to the exposure from the inhaled therapy, suggesting that systemic safety following dermal administration can be bridged to the inhaled program, and offering the potential for a reduced number of studies and/or subjects.

Clinical Uses of Botulinum Neurotoxins: Current Indications, Limitations and Future Developments

PubMed Central

Chen, Sheng

2012-01-01

Botulinum neurotoxins (BoNTs) cause flaccid paralysis by interfering with vesicle fusion and neurotransmitter release in the neuronal cells. BoNTs are the most widely used therapeutic proteins. BoNT/A was approved by the U.S. FDA to treat strabismus, blepharospam, and hemificial spasm as early as 1989 and then for treatment of cervical dystonia, glabellar facial lines, axillary hyperhidrosis, chronic migraine and for cosmetic use. Due to its high efficacy, longevity of action and satisfactory safety profile, it has been used empirically in a variety of ophthalmological, gastrointestinal, urological, orthopedic, dermatological, secretory, and painful disorders. Currently available BoNT therapies are limited to neuronal indications with the requirement of periodic injections resulting in immune-resistance for some indications. Recent understanding of the structure-function relationship of BoNTs prompted the engineering of novel BoNTs to extend therapeutic interventions in non-neuronal systems and to overcome the immune-resistance issue. Much research still needs to be done to improve and extend the medical uses of BoNTs. PMID:23162705
