The gas cutting area has several jobs that are risky to the operator, such as activities with squatting, bending positions. This study aims to determine the risk of work in the gas cutting area as a basis for improving work posture. The method used is RULA (Rapid Upper Limb Assessment) is a research method for investigating disorders of the upper limbs. By measuring the group A score and group B score. Based on the results of the RULA value in the process of operating the machine with a sitting position with a score 3. clearing the cutting plate with a bent position with a score of 5, and the highest score 6 in the grinding plate cutting. To reduce pain in the neck, torso, and arms, operators should not do work postures that cause pain in the body for a long time.

Sinus Pressure

To prevent air embolism and minimize neurosurgical venous hemorrhage, the dural sinus pressure (confluens sinuum pressure, CSP) was examined under various conditions in 47 cases, 11 of whom were children. Either the extracranial (group A) or catheter type (group B) pressure transducer was used. The latter gave approximately 30% higher values than the former. In any surgical position, children showed a tendency toward higher pressure than did adults. This was particularly the case in the sitting position; adults showed negative pressure [-8.6 +/- 2.3 (SD) mmHg, group A], whereas all eight children less than 9 yr of age (group A, 5 cases; group B, 3 cases) showed positive pressure. The youngest with negative CSP in a sitting position was a 9-yr-old boy. When the upper half of the body was raised, the CSP decreased linearly and became zero at approximately 25 degrees. In anteflexion of the neck, the CSP decreased significantly, and even with inclination of the upper half of the body of only 15-20 degrees or more upward, negative pressure was observed in adults. In children, right and left rotation of the neck showed remarkable increase of the CSP. In both supine and sitting positions, CSP was elevated sufficiently by bilateral jugular compression to prevent air embolism. Positive-pressure respiration did not raise the CSP, contrary to widely accepted knowledge. This study was originally performed in relation to brain surgery, but the results also seemed to be valuable in physiology.

Background: Although DC Bead has been useful in treatment of multiple and large hepatocellular carcinoma, loading time of doxorubicin into the DC Bead takes a long time of 30-120 minutes. Epirubicin is also used as an antitumor agent together with DC Bead, but its loading efficiency was not sufficiently elucidated. Methods: To shorten loading time of epirubicin into DC Bead (100-300µm, 300-500µm, 500-700µm), we examined the following three methods after mixing the drug: (a) let stand in room temperature, (b) agitated for 30 seconds with Vortex mixer, and (c) sonicated for 30 seconds with ultrasonic cleaner. After loading of epirubicin by each method, supernatant concentration for epirubicin was assayed at 5, 10, 30, 60, and 120 minutes. Results: Epirubicin loading rates for small bead (100-300µm) at 5 minutes were 82.9 % in group a, 93.8% in group b, and 79.9 % in group c. Similarly, medium bead (300-500µm), 40.1% in group a, 65.7% in group b and 45.5% in group c, respectively. In large-sized bead (500-700µm), loaded rates of epirubicin were 38.8% in group a, 59.0% in group b and 48.0% in group c. Agitation of mixture of epirubicin and DC Bead with Vortex mixer significantly shortened the loading time, but sonication did not affect the time required. Microscopic examination did not lead to any morphological change of microspheres in all the methods. Conclusions: Short time of agitation with Vortex mixer reduced the necessary time for loading of epirubicin in every standard of DC Bead.

Abstract In order to quantitatively assess the effect of sample storage conditions on the body burden analysis of organic contaminants, a comparative analysis was carried out on the unionid mussel Elliptic complanata. The mussels were divided into two groups, each with distinct storage conditions, while Group A was kept in the freezer at −20°C, Group B was kept in the refrigerator for five days at 5°C. All the compounds present in the control were also present in Group B samples. Analysis of the organic contaminants in each of these two groups showed that for total PCB concentrations, the two treatments were not significantly different; however when compared individually 6 of the 13 PCB congeners showed significant differences. The observed differences were relatively small for individual PCB congeners (7.1 to 15.3%), higher for chlorobenzenes (10.5 to 36.4%), and yet higher for HCE (44.1%); the difference for HCE, although large is nevertheless not significant, even if only marginally so.

Abstract Background Repair of a perforated tympanic membrane (myringoplasty) can facilitate normal middle ear function, resist infection, and help re-establish normal hearing. Autogenous graft materials are the most popular graft materials used in myringoplasty because of their easy acceptability by the body. This study is conducted to compare between temporalis fascia graft and fascia lata graft in myringoplasty for patients with tubo-tympanic dry perforation. Results A total of 60 patients with persistent dry tympanic membrane perforation were included in our study during the period from January 2018 to May 2020. Patients underwent myringoplasty with temporalis fascia (30 patients as group A) or fascia lata (30 patients as group B). Patients were scheduled for follow-up visits concerning graft status, ear discharge, and audiograms. The mean postoperative air-bone gap in group A was 17.5 ± 4 after 1 month and 8.6 ± 6.9 after 3 months, while in group B, the mean postoperative air-bone gap was 17.6 ± 4.9 after 1 month and 9.4 ± 7.5 after 3 months. There was 90% success in graft uptake in group A, while there was 80% success in group B. Conclusion Using temporalis fascia is still the best and most trustworthy technique of myringoplasty compared to fascia lata graft. However, fascia lata can be a good alternative to temporalis fascia especially in cases of revision myringoplasty, ears having large perforation, or near-total perforation where the chances of residual perforation are high because of the limited margin of remnant tympanic membrane overlapping the graft.

Abstract Background The early transmitral flow velocity (E) divided by the early diastolic velocity of the mitral valve annulus (e') is referred to as the “E/e' ratio,” is useful even for ST elevation acute myocardial infarction (STEMI). However, the role of late diastolic velocity (a') which reveals the atrial function for STEMI is still unclear. Objectives We evaluated the clinical usefulness of tissue Doppler including atrial function for a first-time STEMI by long time follow up. Furthermore, we evaluated the meaning of each parameters by performing immediately after PCI or 2 weeks later. Methods We treated consecutive 571 first-time STEMI patients by immediate PCI within 12 hours after onset, and we examined 270 patients at immediately after PCI (GroupA, 65 years, 250 male) and 301 patients at 2 weeks after onset (GroupB, 64 years, 243 male). We examined trans mitral flow and TDI, then defined E/e' as LV filling pressure and A/a' as left atrial function. We followed them for a long time (>5 years). The primary end point (PE) was cardiac death or re-admission for heart failure (HF). Results We followed the patients in Group A for 10 years, Group B for 5 years. PE occurred in 64 patients in GroupA during 10 years, and 45 patients in GroupB during 5 years. We analyzed the univariate and multivariate Cox hazard analyses and we compared e' and a', E/e' and A/a' (Table). In GroupA, a' and A/a' were the independent predictors, on the other hand neither a' nor A/a' were the predictors in GroupB. E/e' was an independent predictor both in GroupA and B. Conclusion TDI parameters have different meanings by the timing of echocardiography after onset of a first-time STEMI. These results demonstrated that atrial dysfunction immediately after onset of STEMI suggests the poor prognosis after STEMI.

Objective: Robotic surgical systems offer better workplace in order to relieve surgeons from prolonged physical efforts and improve their surgical outcomes. However, robotic surgery could produce musculoskeletal disorders due to the prolonged sitting position of the operator, the fixed position of the console viewer and the movements of the limbs. Until today, no one study has been reported concerning the association between robotics and musculoskeletal pain. The aim of this work was verify the prevalence of musculoskeletal disorders among Italian robotic surgeons. Material and methods: Between July 2011 and April 2012 a modified Standardized Nordic Questionnaire was delivered to thirty-nine Italian robotic centres. Twentytwo surgeons (56%) returned the questionnaires but only seventeen questionnaires (43.5%) were evaluable. Results: Seven surgeons (41.2%) reported musculoskeletal disorders, by since their first use of the robot which significantly persisted during the daily surgical activity (P < 0.001). Regarding the body parts affected, musculoskeletal disorders were mainly reported in the cervical spine (29.4%) and in the upper limbs (23.5%). Six surgeons (35.3%) defined the robotic console as less comfortable or neither comfortable/uncomfortable with a negative influence on their surgical procedures. Conclusions: In spite of some important limitations, our data showed musculoskeletal disorders due to posture discomfort with negative impact on daily surgical activity among robotic surgeons. These aspects could be due to the lack of ergonomic seat and to the fixed position of the console viewer which could have produced an inadequate spinal posture. The evaluation of these postural factors, in particular the development of an integrated and more ergonomic chair, could further improve the comfort feeling of the surgeon at the console and probably his surgical outcomes.

Metabolism is the natural process of the body, which is necessary to maintenance of the homeostasis of an individual person. Everybody constitutions are always in the process of metabolism, which is a combination of Anabolism (Construction) and Catabolism (Deterioration). As Agni is prime factor for all the Chayapachayakriya. Medoroga, is one of the Metabolic disease, in which contributing factors are Agni, Ama along with Kaphapradhana Tridosha, Medodhathu. Due to various types of etiological factors, the Agni in the body gets vitiated and Jatharagnimandya occurs. By this Jatharagnimandya, Dhathuparinama will not occur properly. This will lead to Medoroga and further many other Upadravas. To correct these conditions, Ayurveda has many modes of therapies like Samshodhana, Samshamana. By these we can correct the metabolism from the root cause. Here 40 Subjects diagnosed with Medoroga w.s.r. to Hyperlipidemia fulfilling the Inclusion criteria were selected for study and randomly categorized into two groups as Group A and Group B each consisting of 20 subjects. For both groups Amapachana with Chitrakadi Vati, Sadhyosnehapana with Murchita Sarshapa Taila, Sarvanga Abhyanga with Murchita Tila Taila followed by Swedana. And Virechana was administered with Virechana Gulika. Than each group received two different Shamanoushadhi. So, the objective of the study is to establish the efficacy of Virechana along with Dashanga Guggulu and Virechana along with Shadushana Guggulu in the management of Medoroga.

Agricultural tasks result in significant strain on the arms, thereby necessitating posture support. One such task is measuring the photosynthetic capacity of individual leaves. This task requires the operator to hold a measuring device for long periods, which is physically demanding. This study aims to develop an assist suit to reduce the physical load involved in photosynthesis measurement work. We used work posture evaluation methods to quantify the workload of this task and identified the parts of the body at high-risk of injury. Then, we designed an assist suit based on the required specifications and verified its effectiveness.

BACKGROUND Supraclavicular brachial plexus block is a reliable, regional anaesthetic technique for upper limb surgeries. Also known as “spinal of upper limb”.1 The present study was conducted to assess the analgesic efficacy of dexamethasone as an adjuvant to 0.5 % ropivacaine for ultrasound sonography (USG) guided brachial plexus block. METHODS 50 adult patients of American Society of Anaesthesiologists (ASA) physical status I and II of both genders, aged 18 - 50 years scheduled for elective upper limb surgeries under brachial plexus block via supraclavicular approach were randomised into 2 groups of 25 patients each to receive either 20 ml of 0.5 % ropivacaine with 2 ml of normal saline (group A) or 20 ml of 0.5 % ropivacaine with 2 ml of dexamethasone (8 mg) (group B). RESULTS Use of ultrasound helps in better visualisation of nerves, needle & spread of local anaesthetic at brachial plexus block site. So, less amount of drug volume is required for the block. Time of onset of sensory and motor block was significantly lower in group B compared to group A. Mean duration of motor and sensory block was significantly longer in group B than group A. The duration of postoperative analgesia was 18.79 ± 2.31 hours in group B & 9.06 ± 0.35 hours in group A, with statistically highly significant difference (P < 0.05). There were no perioperative haemodynamic variations between the two groups and no complication of technique or adverse effects due to dexamethasone occurred. CONCLUSIONS Dexamethasone 8 mg has significantly extended duration of analgesia of brachial plexus block with no adverse effects.

Shoulder pain is a common complication of a stroke which can impede participation in rehabilitation and has been associated with poor outcomes. Low Level LASER Therapy (LLLT) is one of the adjunct treatments of choice with exercise therapy for shoulder rehabilitation in Physiotherapy. The objective of this study was to investigate the effect of LLLT on Hemiplegic Shoulder Pain (HSP) in reducing shoulder pain and improving upper limb function in post Stroke subjects. Prospective study design. 68 subjects with mean age of 53 years having a clinical diagnosis of Stroke with HSP were randomly allocated into two groups. In Group-A (n=34) subjects were treated with LLLT and standardized Rehabilitation Programme, where as in Group-B (n=34) subjects were treated with standardized Rehabilitation Programme. Participants were given interventions twice a week for 8 weeks. The outcomes of this intervention were measured by SPADI for pain, disability and FMA-UE for function. Statistical analysis of the data revealed that within group comparison both groups showed signicant improvement in all parameters, where as in between groups comparison Group-A showed better improvement compared to the Group-B. After 8 weeks of interventions both Group-A and Group-B showed signicant improvement in reducing pain and improving upper limb function. However LLLT along with Standardized Rehabilitation Programme showed more improvement when compared to the Standardised Rehabilitation Programme alone. Thus this study concludes that LLLT is a useful adjunct in HSPalong with rehabilitation
