Multitask Interactive Attention Learning Model Based on Hand Images for Assisting Chinese Medicine in Predicting Myocardial Infarction.

Acute myocardial infarction (AMI) is one of the most serious and dangerous cardiovascular diseases. In recent years, the number of patients around the world has been increasing significantly, among which people under the age of 45 have become the high-risk group for sudden death of AMI. AMI occurs quickly and does not show obvious symptoms before onset. In addition, postonset clinical testing is also a complex and invasive test, which may cause some postoperative complications. Therefore, it is necessary to propose a noninvasive and convenient auxiliary diagnostic method. In traditional Chinese medicine (TCM), it is an effective auxiliary diagnostic strategy to complete the disease diagnosis through some body surface features. It is helpful to observe whether the palmar thenar undergoes hypertrophy and whether the metacarpophalangeal joint is swelling in detecting acute myocardial infarction. Combined with deep learning, we propose a depth model based on traditional palm image (MTIALM), which can help doctors of traditional Chinese medicine to predict myocardial infarction. By building the shared network, the model learns information that covers all the tasks. In addition, task-specific attention branch networks are built to simultaneously detect the symptoms of different parts of the palm. The information interaction module (IIM) is proposed to further integrate the information between task branches to ensure that the model learns as many features as possible. Experimental results show that the accuracy of our model in the detection of metacarpophalangeal joints and palmar thenar is 83.16% and 84.15%, respectively, which are significantly improved compared with the traditional classification methods.

Case Report: Treatment of a Severe Puff Adder Snakebite Without Antivenom Administration.

Antivenoms are the treatment of choice for managing lethal snakebites. However, antivenoms may not be available in instances where non-native vipers are kept in captivity. We report a case of a puff adder (Bitis arietans) bite treated without antivenom. A 23-year-old man was bitten on his left hand by a puff adder that he illegally kept in his house. The swelling spread rapidly to the upper arm and there was a risk of bleeding, suggesting the need for antivenom administration, but this could not be acquired because of lack of stock. We initiated fluid resuscitation and administered recombinant thrombomodulin (rTM) to prevent venom-induced consumption coagulopathy. In addition, hyperbaric oxygen (HBO) treatment was also performed to reduce local swelling. The patient recovered without complications after the multidisciplinary treatment. Further studies are needed to prove the safety and efficacy of rTM administration and HBO therapy as an adjunct or alternative therapy with antiserum for fatal snakebite.

No efficacy of biofield therapy in the treatment of warts of the hands and feet in adults: a randomized controlled trial.

Although biofield therapy is unexplained by scientific evidence, it has been practised for many years in numerous cultures for a variety of medical conditions. This study aimed to determine whether one session of biofield therapy with an experienced practitioner could treat warts on the hands and feet in adults. A single-blind, assessor-blind, placebo-controlled, randomized trial was performed between April 2016 and November 2018. The enrolled participants had at least one wart on the hand or foot that had been present for at least 90 days and they were not using any other therapy for the wart. The primary outcome of this trial was the disappearance of the original wart 3 weeks after session of proximal nontouch biofield therapy vs. a sham session. No original wart had disappeared 3 weeks after intervention (0/64), which made the study impossible to conclude on the primary objective. There were no significant differences between the two groups concerning wart disappearance 3 weeks (P = 0.49) or 6 weeks (P = 0.40) after the intervention. Reduction in wart size at Week 3 tended towards a better result for biofield therapy but this was not significant (P = 0.27). No related adverse effects were observed. The major limitation of this trial was the short follow-up time for measurement of clinical outcome, which did not allow verification of the hypothesis. However, this study shows that 3 weeks after a session of proximal nontouch biofield therapy is an insufficient length of time to assess biofield therapy in comparison with a sham session. Based on this study, biofield therapy cannot be recommended to treat warts within 3 weeks.

A Review of the Phenotype of Synpolydactyly Type 1 in Homozygous Patients: Defining the Relatively Long and Medially Deviated Big Toe with/without Cupping of the Forefoot as a Pathognomonic Feature in the Phenotype.

Synpolydactyly type 1 (SPD1, OMIM 186000) is inherited as autosomal dominant and is caused by HOXD13 mutations. The condition is rare and is known for its phenotypic heterogeneity. In the homozygous state, the phenotype is generally more severe and is characterized by three main features: a more severe degree of syndactyly, a more severe degree of brachydactyly, and the frequent loss of the normal tubular shape of the metacarpals/metatarsals. Due to the phenotypic heterogeneity and the phenotypic overlap with other types of syndactyly, no pathognomonic feature has been described for the homozygous phenotype of SPD1. In the current communication, the author reviews the literature on the phenotypes of SPD1 in homozygous patients. The review documents that not all homozygous patients show a severe hand phenotype. The review also defines the "relatively long and medially deviated big toe with/without cupping of the forefoot" as a pathognomonic feature in the phenotype. Illustration of this feature is done through a demonstrative clinical report in a multigeneration family with SPD1 and HOXD13 polyalanine repeat expansion. Finally, the pathogenesis of the clinical features is reviewed.

Effect of flaxseed poultice compress application on pain and hand functions of patients with hand osteoarthritis.

INTRODUCTION/OBJECTIVES: This randomized controlled intervention study investigated the effect of flaxseed poultice compress application on pain and hand functions in patients with primary interphalangeal hand osteoarthritis (OA). METHOD: The study sample consisted of 82 patients who met the inclusion criteria in the Rheumatology Outpatient Clinic at a University Hospital between January 15, 2017, and May 15, 2018. Patients included in the sample groups were selected randomly. Three sample groups were formed: intervention group I (flaxseed poultice compress) (n = 33), intervention group II (hot compress) (n = 29), and control group (n = 20). The interventions were applied once a day for 7 days in a row. These patients also continued their routine pharmacological treatment. descriptive characteristics identification form, visual analog scale (VAS), Australian-Canadian (AUSCAN) Osteoarthritis (OA) Hand Index, and side effect evaluation form were used as data collection tools. RESULTS: The means of VAS scores of patients in the intervention group I were 6.03 ± 0.25 on day 0, 2.2 ± 0.30 on day 8, and 3.39 ± 0.32 on day 15. The means of AUSCAN total scores of patients in the intervention group I were 40.84 ± 1.76 on day 0, 14.03 ± 1.66 on day 8, and 15.78 ± 1.66 on day 15. The present study showed that pain significantly decreased and the hand function efficiency increased in patients treated with flaxseed poultice compress compared with the hot compress and control groups. CONCLUSIONS: In addition to pharmacological treatment, flaxseed poultice compress intervention is recommended to be used as a nursing intervention for reducing pain and increasing hand functions for patients with hand OA in cooperation with the physicians and other health professionals.

Talk to the Hand: U.S. Army Biophysical Testing.

BACKGROUND: Many people are unaware of the science underlying the biophysical properties of Soldier clothing and personal protective equipment, yet there is a well-refined biomedical methodology initiated by Army physiologists in World War II. This involves a methodical progression of systematic material testing technologies, computer modeling, and human testing that enables more efficient development and rapid evaluation of new concepts for Soldier health and performance. Sophisticated manikins that sweat and move are a central part of this testing continuum. This report briefly summarizes the evolution and use of one specialized form of the manikin technologies, the thermal hand model, and its use in research on Soldier hand-wear items that sustain dexterity and protect the hand in extreme environments. METHODS: Thermal manikin testing methodologies were developed to provide an efficient and consistent analytical tool for the rapid evaluation of new clothing concepts. These methods have been upgraded since the original World War II and Korean War eras to include articulation and sweating capabilities, as characterized and illustrated in this article. The earlier "retired" versions of thermal hand models have now been transferred to the National Museum of Health and Science. FINDINGS: The biophysical values from manikin testing are critical inputs to the U.S. Army Research Institute of Environmental Medicine mathematical models that provide predictions of soldier comfort, duration of exposure before loss of manual dexterity, and time to significant risk of freezing (skin temperature <-1°C) and nonfreezing cold injuries (skin temperature <5°C). The greater thickness of better insulated handwear reduces dexterity and also increases surface area which makes added insulation increasingly less effective in retaining heat. Measurements of both thermal resistance (insulation) and evaporative resistance (permeability) collectively characterize the biophysical properties and enable mathematical modeling of the human thermophysiological responses. This information can help guide the hand-wear development and selection process which often requires trade-offs between factors such as material, cost, and sizing. IMPACT: Soldier hands provide fine motor dexterity in tactical functions, ranging from pulling a trigger to pulling a parachute ripcord; thus, protecting hand function is critical to soldier readiness. Also, the importance of protection against nonbattle cold injuries was highlighted during World War II in northern Europe, in the Aleutian Islands, and later in Korea. The U.S. Army has been on the forefront of the biophysical analysis of clothing including gloves since environmental research was established at the Armored Medical Research Laboratory and Climatic Research Laboratory during World War II. U.S. Army Research Institute of Environmental Medicine does not make the equipment but works with their Natick Soldier Research, Development, and Engineering Center partners to make the equipment better.

The Effect of Therapeutic Whirlpool and Hot Packs on Hand Volume During Rehabilitation After Distal Radius Fracture: A Blinded Randomized Controlled Trial.

BACKGROUND: Edema is a possibility with all heating modalities due to the increase in local blood flow caused by vasodilation. Despite the frequent application of superficial heat modalities, their relative effect on hand volume has not been determined for the upper extremity. The objective of this study was to compare the immediate effects of hot packs and whirlpool on hand volume for patients with distal radius fracture (DRF) and to determine whether any changes in volume between these modalities were still present 30 minutes after heat application. Finally, to determine whether there were any differences in volume change between groups after 3 repeated therapy visits. METHODS: Sixty patients with clinically healed DRFs were divided into 2 groups. Half received therapeutic whirlpool at each therapy visit, and the other half received a moist hot pack treatment for 3 consecutive visits. Hand volume was measured before heat, after heat, and at the end of each 30-minute therapy session. RESULTS: There was a significant difference between groups immediately after heat application, as patients in the whirlpool group experienced an initial volume increase greater than those who received a hot pack. When remeasured after a hand therapy session approximately 30 minutes later, this group difference in volume change was no longer significant. The overall change in volume from enrollment in the study to completion of the study 3 weeks later was not statistically different between groups. CONCLUSION: Whirlpool is a potential consideration when selecting a heat modality for patients with DRF.

Rewiring the primary somatosensory cortex in carpal tunnel syndrome with acupuncture.

Carpal tunnel syndrome is the most common entrapment neuropathy, affecting the median nerve at the wrist. Acupuncture is a minimally-invasive and conservative therapeutic option, and while rooted in a complex practice ritual, acupuncture overlaps significantly with many conventional peripherally-focused neuromodulatory therapies. However, the neurophysiological mechanisms by which acupuncture impacts accepted subjective/psychological and objective/physiological outcomes are not well understood. Eligible patients (n = 80, 65 female, age: 49.3 ± 8.6 years) were enrolled and randomized into three intervention arms: (i) verum electro-acupuncture 'local' to the more affected hand; (ii) verum electro-acupuncture at 'distal' body sites, near the ankle contralesional to the more affected hand; and (iii) local sham electro-acupuncture using non-penetrating placebo needles. Acupuncture therapy was provided for 16 sessions over 8 weeks. Boston Carpal Tunnel Syndrome Questionnaire assessed pain and paraesthesia symptoms at baseline, following therapy and at 3-month follow-up. Nerve conduction studies assessing median nerve sensory latency and brain imaging data were acquired at baseline and following therapy. Functional magnetic resonance imaging assessed somatotopy in the primary somatosensory cortex using vibrotactile stimulation over three digits (2, 3 and 5). While all three acupuncture interventions reduced symptom severity, verum (local and distal) acupuncture was superior to sham in producing improvements in neurophysiological outcomes, both local to the wrist (i.e. median sensory nerve conduction latency) and in the brain (i.e. digit 2/3 cortical separation distance). Moreover, greater improvement in second/third interdigit cortical separation distance following verum acupuncture predicted sustained improvements in symptom severity at 3-month follow-up. We further explored potential differential mechanisms of local versus distal acupuncture using diffusion tensor imaging of white matter microstructure adjacent to the primary somatosensory cortex. Compared to healthy adults (n = 34, 28 female, 49.7 ± 9.9 years old), patients with carpal tunnel syndrome demonstrated increased fractional anisotropy in several regions and, for these regions we found that improvement in median nerve latency was associated with reduction of fractional anisotropy near (i) contralesional hand area following verum, but not sham, acupuncture; (ii) ipsilesional hand area following local, but not distal or sham, acupuncture; and (iii) ipsilesional leg area following distal, but not local or sham, acupuncture. As these primary somatosensory cortex subregions are distinctly targeted by local versus distal acupuncture electrostimulation, acupuncture at local versus distal sites may improve median nerve function at the wrist by somatotopically distinct neuroplasticity in the primary somatosensory cortex following therapy. Our study further suggests that improvements in primary somatosensory cortex somatotopy can predict long-term clinical outcomes for carpal tunnel syndrome.

Assessment of a Novel Anti-Aging Hand Cream.

There are few creams that have been developed for the purpose of treating the aging hand, yet UV damage and secondary signs of aging on the hands make them one of the most obvious indicators of age outside the face. This study documents results of a 120 day trial using a novel cream preparation containing ingredients including Retinol, Alpha-Arbutin, Kojic Dipalmitate, Azaeleic Acid, Hexylresorcinol, Licorice Root, and other ingredients. Results were tabulated comparing physician and patient assessment scores using a comprehensive scoring assay, which showed significant improvements across eight parameters tested. This was statistically significant for physician ratings of texture, wrinkles and pigment at 120 days versus baseline (P < 0.001). Further research is needed, but the results appear to indicate the benefits of a targeted hand cream in improving the appearance of the aging hand.

Evaluation of the Safety and Efficacy of a Low Fluence, Picopulsed, Alexandrite Laser in a Pico-Toning Technique With a Diffractive Lens Optic for the Treatment of Photodamage and Textural Improvement in "Off the Face" Applications.

BACKGROUND: The diffractive optic coupled with a picosecond pulsed alexandrite laser has been shown to effectively minimize pigmen- tation while improving the appearance of textural irregularities and rhytides. We evaluated the safety and ef cacy of the diffractive optic laser treatment for off of the face applications including the hands and décolletage in a pico-toning technique. STUDY: 20 healthy female patients (40-70 years of age) were treated with a picosecond pulsed alexandrite laser with a diffractive lens. 10 of the patients were enrolled in a prospective hand assessment study (20 hands) while the remaining 10 subjects were enrolled in an IRB approved study treating photodamage of the décolletage. Protocol for both groups included 4 treatments to the designated area with a picopulsed alexandrite laser with a diffractive lens on a 6mm handpiece delivering 0.71 j/cm2 with 10 hz repetition at 3 week intervals (+- 7 days) with follow up at 1 month and 3 months post fourth treatment using standardized digital photography. RESULTS: Statistically signi cant improvement in the overall appearance of pigmentation, texture and rhytides were recorded at each sub- sequent visit and at 1 and 3 months post the nal laser treatment. Clinical photographs were evaluated from baseline to the final photo at 3 months post last laser treatment by the treating physician, patient, and an independent evaluator. All hand subjects and chest subjects showed improvement in all 3 areas which were found to be statistically signi cant. No adverse events occurred in either study group. CONCLUSION: These study results show signi cant improvement in not only pigmentation, but in texture and rhytides in all subjects receiving pico-toning laser treatments to off of the face areas. The laser was well tolerated by all patients with no adverse effects. The use of a diffractive lens optic on a 6 mm xed spot size handpiece with a picopulsed alexandrite laser, in a pico-toning technique, provides a safe, low uence, yet effective treatment for not only pigment dyschromia but also textural irregularities and rhytides when treating the hands and décolletage.

[Sarcoma of the hand and wrist]. / Sarkome an Hand und Handgelenk.

Sarcomas of the hand and wrist are rare malignancies, which should be referred to high-volume comprehensive cancer centres providing multidisciplinary treatment options. The tumour board should propose patient-oriented oncological pathways as well as sophisticated hand and plastic reconstructive procedures. In Addition, isolated limb perfusion with TNF-alpha and melphalan is likely to lead to preoperative tumour shrinkage allowing for R0 resection in sano. Our clinical results in long-term survivors demonstrate reduced amputation rates and salvage of basic hand function when a risk-adapted treatment rationale is applied.

Mycosis fungoides palmaris et plantaris successfully treated with radiotherapy: case report and mini-review of the published work.

Mycosis fungoides palmaris et plantaris (MFPP) is a rare variant of cutaneous T-cell lymphoma limited to the palms and soles that is not widely recognized because of its uncommon occurrence. We report a 73-year-old Japanese man who presented with an erosion on the left dorsal hand, a reddish tumor on the right palm, and hyperkeratotic erythematous plaques on the right sole. Skin biopsy showed histological features of mycosis fungoides (MF) with invasion into the deeper layers of skin. There was no visceral or lymph node invasion. We diagnosed this case as MFPP. External beam radiotherapy (EBRT) was performed to treat the hand lesions. Combination treatment with topical steroids and topical psoralen plus ultraviolet light therapy was performed to treat the right sole lesion, but was ineffective. Therefore, sequential EBRT was performed. Complete remission of all lesions was obtained. This is the first report of MFPP with a locally advanced tumor for which the efficacy of radiotherapy is described in detail. MFPP lesions occur on the dorsal aspect of hand or foot, and here we propose a classification of MFPP as hand and foot MF. The pathogenesis of MFPP is still unclear and further accumulation of data is required.

Estudio observacional sobre las técnicas de punción del bloqueo axilar para cirugía de mano en pacientes ambulantes en un hospital universitario: Aportes a la ecografía / No disponible

Objetivos: Valorar el aporte de la ecografía para la realización de bloqueos axilares en cirugía mayor ambulatoria con tres tipos de técnicas. Material y métodos: Estudio observacional, prospectivo en pacientes programados para cirugía de manos. Se construyó una base con datos demográficos, el tipo y eficacia de la técnica en cuanto al bloqueo motor y sensitivo, dolor posoperatorio, el grado de satisfacción y complicaciones asociadas. Las tres técnicas estudiadas fueron el uso de neuroestimulador, el uso de la ecografía y la combinación de ambas. Resultados: Se recogieron 151 casos. 77(51 %) se realizaron con NS solo, 36 (24 %) combinando la técnica de NS con Eco, y 38 (25 %) con Eco solo. 15 (20 %) pacientes puncionados con NS requerían un refuerzo de anestesia local versus 14 (38,9 %) en el grupo NS + Eco y 1 (2,6 %) en el grupo Eco solo (p < 0,001). La técnica combinada NS + Eco ha permitido bajar más el volumen de anestésico local comparado con la técnica Eco sola (NS + Eco: 26,2 ± 7,3; Eco solo: 31,4 ± 5,6; p = 0,001). En las 24 primeras horas posoperatorias, no hubo diferencias significativas en el consumo de analgésicos (p = 0,59). El índice de satisfacción era alto y comparable entre los tres grupos (NS: 8,4 ± 1,7/10; NS + Eco: 8,5 ± 1,9/10; Eco: 9,0 ± 1/10; p = 0,17). No hubo complicaciones ni reingresos a las 24 horas de la realización del bloqueo. Conclusión: La técnica ecográfica es segura y permite aumentar la seguridad del bloqueo con una eficacia equivalente o mejor a la técnica neuroestimulada. En cambio, la combinación de las 2 técnicas, da peores resultados, por lo que no recomendamos su uso (AU)

Objective: Asses the role of ultrasound guided axillary block in hand day case surgery with three different techniques. Materials and methods: we design a prospective, observational study in patients scheduled for day case hand surgery. Demographics data, type and efficiency of technique regarding sensitive and motor block, postoperative pain, satisfaction survey and complications were recorded. Block using neurostimulator (NS), ultrasound guide (US) and the combination of both was evaluated (NS+US). Results: 151 patients were included. 77 (51 %) were performed only by NS, 36 (24 %) using both techniques and 38 (25 %) with US solely. 15 (20 %) patients blocks by NS required an extra dose of local anesthetic in relation to 14 (38.9 %) in NS + US group and only 1 patient (2.6 %) block using US (p < 0.001). The combination technique allow to reduce total volume of local anesthetic used respect US guide block (NS + US: 26.2 ± 7.3; US: 31.4 ± 5.6; p = 0.001). In the first postoperative day, no different in analgesic consumption between three groups was found (p = 0.59).The satisfaction was high and comparable in all patients regardless of the technique used (NS: 8.4 ± 1.7/10; NS + US: 8.5 ± 1.9/10; US: 9.0 ± 1/10; p = 0.17). No complications and readmission was reported. Conclusion: US guided are a safe technique and make possible to increase block safety and efficiency. Nevertheless, the combination technique gives worse results and we should avoid their use (AU)

The tropical diabetic hand syndrome: a surgical perspective.

Tropical diabetic hand syndrome (TDHS) is an aggressive type of hand sepsis that results in significant morbidity and mortality among patients with diabetes in the tropics. This study set out to establish a protocol for the holistic management of TDHS to improve digit/hand salvage and function at AIC Kijabe Hospital. This prospective study examined the following demographics of patients presenting to the authors institution between October 2009 and September 2010 with TDHS: their sex, age, comorbidities, length of in-hospital stay, surgical and medical treatment, total cost of treatment, and immediate postdischarge outcomes. A total of 10 patients (3 men and 7 women) were presented with TDHS during the study period. Surgical procedures included a thorough debridement of the hand at initial presentation, followed by procedures aimed at preserving length and hand function, with digit or hand amputation when there was no possibility of salvage. Three hands were salvaged, without the need for an amputation; 2 of these, however, developed severe stiffness with resultant poor function. Fifty percent of the patients developed considerable disability; 3 of these patients had disabilities of the arm, shoulder, and hand, (DASH) scores of >90 at 6 months after treatment. TDHS appears to be more aggressive in some patients than in others; a multidisciplinary approach, with early involvement of the surgical team, and a radical surgical debridement are essential to improved outcomes. Although the goal of medical treatment (ie, glycemic control) is simple and easily achieved, surgical goals (salvage of limb or life, preservation of hand function) are more complex, costly, and difficult to achieve. Educating health care workers, diabetic patients, and their relatives on hand care is an important preventive measure. Diligence in taking antidiabetic medicine, early presentation, and appropriate care of TDHS are required for meaningful improvement in outcomes of patients with diabetes who develop hand sepsis in the tropics.

A prospective, noninterventional study of the treatment of the aging hand with Juvéderm Ultra® 3 and Juvéderm ® Hydrate.

BACKGROUND: Hand rejuvenation aims to restore volume and produce smooth, elastic skin. A combined treatment has been proposed: Juvéderm Ultra® 3 for filling and smoothing the skin and Juvéderm® Hydrate to rehydrate and restore skin quality. METHODS: Twenty physicians enrolled 99 subjects (i.e., 198 hands). At the first visit, hands were injected with Juvéderm Ultra® 3. At the second visit (day 15) hands were treated with Juvéderm® Hydrate. A final assessment was made at day 30. RESULTS: Ninety-eight percent of subjects were female (mean age=60.3 years). Mean volumes injected were 1.02 ml Juvéderm Ultra® 3 per hand at day 0 and 0.91 ml Juvéderm® Hydrate per hand at day 15. Mean grading on the Hand Aging Scale was 3.18 preinjection, which decreased to 1.73 on study completion (p<0.0001). Injections were rated as "very easy/easy" in 99.4 and 98.9% of cases for Juvéderm Ultra® 3 and Juvéderm® Hydrate, respectively. Most physicians found both products "very easy/easy" to massage. Physician evaluation based on the Global Aesthetic Improvement Scale (GAIS) showed that the proportion of "very much/much improved" was significantly higher at days 15 and 30 compared to baseline (63.7 and 70.3 vs. 41.8%). Patient GAIS scores showed that the proportion of "much improved" was significantly higher at day 30 than at day 15 (53.1 vs. 43.9%). Over 94% of physicians and approximately 90% of subjects would recommend treatment. The adverse event rate was 8.2 %, including edema, hematoma, redness, and pain. CONCLUSION: Combined Juvéderm Ultra® 3 and Juvéderm® Hydrate treatment is effective and safe for rejuvenating the aging hand.
