Single-blind randomized clinical trial, with a follow-up of 24 weeks. To determine the effects of hyperthermia via localized microwave diathermy on pain and disability in comparison to subacromial corticosteroid injections in patients with rotator cuff tendinopathy. Hyperthermia improves symptoms and function in several painful musculoskeletal disorders. However, the effects of microwave diathermy in rotator cuff tendinopathy have not yet been established. Ninety-two patients with rotator cuff tendinopathy and pain lasting for at least 3 months were recruited from the outpatient clinic of the Department of Orthopaedics and Traumatology, University Hospital, Rome, Italy. Participants were randomly allocated to either local microwave diathermy or subacromial corticosteroids. The primary outcome measure was the short form of the Disabilities of the Arm, Shoulder and Hand Questionnaire (QuickDASH). Secondary outcome measures were the Constant-Murley shoulder outcome score and a visual analog scale for pain assessment. At the end of treatment and at follow-up, both treatment groups experienced improvements in all outcome measures relative to baseline values. Changes over time in QuickDASH, Constant-Murley, and visual analog scale scores were not different between treatment arms. In patients with rotator cuff tendinopathy, the effects of localized microwave diathermy on disability, shoulder function, and pain are equivalent to those elicited by subacromial corticosteroid injections.

Hemorrhoidectomy is the most effective long-term treatment for hemorrhoids. Although it is possible to perform hemorrhoidectomy as a day case with a high degree of patient satisfaction, patients take an average of 14 days off work after surgery. Stapled hemorrhoidectomy is believed to be less painful than conventional hemorrhoidectomy and should allow an earlier return to work. The aim of this study was to compare both the immediate and the long-term results of stapled hemorrhoidectomy with diathermy hemorrhoidectomy in patients with prolapsing internal hemorrhoids in an intended day-care setting. Thirty-one patients were randomly assigned to undergo diathermy hemorrhoidectomy (n = 16) or stapled hemorrhoidectomy performed with a purpose-designed endoluminal stapling device, PPH01T (n = 15). All operations were planned as day or short-stay cases. All patients received lactulose, commenced preoperatively, together with postoperative topical glyceryl trinitrate and oral metronidazole. Patients were assessed by structured interview to assess their symptoms before and after surgery, with an intended follow-up of six months. All patients completed a 10-cm visual analog pain scale daily for the first ten days after surgery. The total pain score (sum of all pain scores) was significantly higher in the diathermy group (50 (range, 9.8-79.9) vs. 19.6 (range, 1.3-89.5), P = 0.03). Patients took a median of 14 (range, 3-21) days off work after diathermy hemorrhoidectomy compared with 10 (range, 3-38) days for the patients undergoing stapled hemorrhoidectomy (P = 0.15). At long-term follow-up, three patients (all in the stapled group) developed new symptoms of fecal urgency and anal pain, and three patients required further surgery to remove symptomatic external hemorrhoids after stapled hemorrhoidectomy. Although stapled hemorrhoidectomy is less painful in the short term, this does not lead to a significantly earlier return to work, and some patients develop new symptoms at

Objective Post-tonsillectomy hemorrhage remains an important factor in determining the safety of performing tonsillectomy as a day case procedure. The aim of this study was to determine the safety of day case tonsillectomy by using combination method, cold dissection tonsillectomy and bipolar diathermy hemostasis. Methods A prospective randomized clinical study conducted on the patients who had undergone day case tonsillectomy (DCT). There were two groups (DCT and control group) each group consisting of 150 cases. Tonsillectomy was performed by using combination method; cold dissection and hemostasis was achieved by ligation of vessels with bipolar electerocautery. Findings We found 3 cases of post-tonsillectomy bleeding in DCT group and 4 cases in the control group. There was no statistically significant difference in the rate of post-operative hemorrhage between the two groups. Conclusion The findings suggest the safety of the combination of cold dissection tonsillectomy and bipolar diathermy hemostasis as day case tonsillectomy. PMID:23056702

To report the effects of local microwave diathermy (hyperthermia) at 434 Mhz on calcific tendinopathy of the shoulder in two middle aged patients. Two middle-aged women with calcific tendinopathy of the shoulder were treated with local microwave diathermy (hyperthermia) at 434 Mhz three times a week for four weeks. Plain radiographs and ultrasonography demonstrated calcific deposits in the area of infraspinatus or supraspinatus. Shoulder Pain and Disability Index (SPADI) and passive Range of Motion (ROM) were used to assess the response to treatment. At the end of the treatment period, the improvement as measured by the SPADI score was respectively 30% for the first patient and 40% for the second patient with an improvement of the shoulder passive ROM for both patients. The calcific deposits seen on the initial radiographs and ultrasonography were no longer visible. At 1 year follow-up, both patients continued to be symptom free. Hyperthermia is a safe option in the management of calcific tendinopathy of the shoulder. Prospective randomized controlled studies with long term assessment are needed to further document its therapeutic efficacy.

AIM: To compare hemorrhoidectomy with a bipolar electrothermal device or hemorrhoidectomy using an ultrasonically activated scalpel. METHODS: Sixty patients with grade III or IV hemorrhoids were prospectively randomized to undergo closed hemorrhoidectomy assisted by bipolar diathermy (group 1) or hemorrhoidectomy with the ultrasonic scalpel (group 2). Operative data were recorded, and patients were followed at 1, 3, and 6 wk to evaluate complications. Independent assessors were assigned to obtain postoperative pain scores, oral analgesic requirement and satisfaction scores. RESULTS: Reduced intraoperative blood loss median 0.9 mL (95% CI: 0.8-3.7) vs 4.6 mL (95% CI: 3.8-7.0), P = 0.001 and a short operating time median 16 (95% CI: 14.6-18.2) min vs 31 (95% CI: 28.1-35.3) min, P < 0.0001 was observed in group 1 compared with group 2. There was a trend towards lower postoperative pain scores on day 1 group 1 median 2 (95% CI: 1.8-3.5) vs group 2 median 3 (95% CI: 2.6-4.2), P = 0.135. Reduced oral analgesic requirement during postoperative 24 h after operation median 1 (95% CI: 0.4-0.9) tablet vs 1 (95% CI: 0.9-1.3) tablet, P = 0.006 was observed in group 1 compared with group 2. There was no difference between the two groups in the degree of patient satisfaction or number of postoperative complications. CONCLUSION: Bipolar diathermy hemorrhoidectomy is quick and bloodless and, although as painful as closed hemorrhoidectomy with the ultrasonic scalpel, is associated with a reduced analgesic requirement immediately after operation.

Although shortwave diathermy has been widely used by physiotherapists, there are a few studies assessing the performance of the equipment in use. The aim of the present study was to evaluate the procedures adopted by physiotherapists as users of shortwave diathermy continuous (CSWD), as well as to measure the power output and frequency of CSWD equipment. [Subjects and Methods] Twenty-three physical therapists were interviewed and 23 CSWD equipment were evaluated. Admeasurement was carried out by using a standard phantom to simulate the electrode-skin distance, which ranged from 0.5 to 3.0 cm. Data analysis was performed by using descriptive statistics, ANOVA, and a post-hoc Tukey's test or Pearson's correlation coefficient. [Results] The questionnaires showed that 48% of the interviewees use the correct electrode-skin distance, 70% use a single electrical outlet, and 35% use a grounded electrical outlet, and that 48% of the physiotherapy tables and 61% of the plinths were made of wood. However, only 13% of the interviewees perform yearly preventive maintenance. The highest power (95.56 W) was achieved at electrode-skin distances ranging from 1.0 to 1.5 cm, with distances of 2.5 cm and 3.0 cm being null in four and eight equipment, respectively. There was a negative correlation between power output and electrode-skin distance as well as between power output and purchase date. [Conclusion] The physiotherapists involved in this study had inadequate knowledge about the correct use of CSWD equipment, which may adversely affect its performance and patient safety.

An economic evaluation of laparoscopic ovarian diathermy versus gonadotrophin therapy for women with clomiphene citrate-resistant polycystic ovarian syndrome.

2005-08-01

Women with polycystic ovarian syndrome are typically anovulatory and require ovulation induction. Ovarian wedge resection was the first treatment for anovulation but was eventually abandoned because of the increased risk of postsurgical adhesions and as medical ovulation induction with clomiphene and gonadotrophins was introduced. However, with the advent of laparoscopy, there has been a return to surgical approaches. The potential advantages of laparoscopic surgery include avoidance of hyperstimulation and the lowered costs make ovarian surgery an attractive alternative to gonadotrophins. Clinical trials in New Zealand and the Netherlands have compared costs of laparoscopic ovarian drilling with gonadotrophins. The total cost of treatment in the Netherlands study for the ovarian drilling group was euro 4664 and for the gonadotrophins group was euro 5418. Without the cost of monitoring and the diagnostic laparoscopy then the difference was euro 2110 in favour of ovarian drilling. It was estimated that the cost per term pregnancy would be euro 14,489 for gonadotrophin and euro 11,301 for ovarian drilling (22% lower). The higher rates of multiple pregnancy in the gonadotrophin group were considered to be responsible for the increased costs. In the New Zealand trial the costs of a live birth were one-third lower in the group that underwent laparoscopic ovarian diathermy compared with those women who received gonadotrophins (NZ$19,640 and 29,836, respectively). Treating women with clomiphene-resistant polycystic ovarian syndrome with laparoscopic ovarian diathermy results in reduced direct and indirect costs. The reduction in multiple pregnancies makes the alternative of surgery particularly attractive.

To compare the efficacy of carbon dioxide (CO(2)) laser with cutting diathermy as a cutting device in surgical excision of early carcinoma tongue. Experimental study. Combined Military Hospital (CMH), Rawalpindi and CMH, Lahore, from July 2008 to July 2011. Twenty two biopsy proven cases of T(1) and early T(2) squamous cell carcinoma of tongue were divided in two equal groups of 11 each labeled as A and B. Tumor was excised by CO(2) laser in group A while cutting diathermy was done in group B. For both groups tumor excision time, per-operative blood loss, postoperative oral swelling and pain was recorded. Excision time of tumor was assessed in minutes and amount of blood loss in milliliters till complete hemostasis after removal of primary tumor. Postoperatively patients were assessed on 12 hourly basis for 48 hours for pain. Pain was analyzed on visual analogue score 1 - 10. Oral swelling was assessed once after 24 hours and labeled as mild, moderate and severe. Independent sample t-test was applied for analysis of excision time, postoperative pain and per-operative blood loss for both groups. Postoperative swelling was analyzed using Fisher's exact test. P-value of < 0.05 was considered significant. The mean age at diagnosis in group A was 49.36 ± 5.27 years, while in group B patients had mean age of 50.73 ± 8.13 years. In group A, 4/11 (36.3%) patients were having tumor stage T(1) while 7/11 (63.6%) had T(2) stage tumor. In group B, 5/11 (45.4%) were having T1 and 6/11 (54.5%) were having stage T(2) tumor. Excision time was significantly shorter for group B (p=0.003), but group A had less postoperative pain (p=0.001), less per-operative blood loss (p=0.001) and less postoperative oral swelling (p=0.021). Early carcinoma tongue is better removed by laser than electrocautery in terms of postoperative morbidity, per-operative blood loss, postoperative pain and oral swelling.

Nonpharmacological therapies for tension-type headache (TTH) and cervicogenic cephalalgia are often a treatment choice, despite the weak to moderate evidence. The aim of this study was to compare the effectiveness of an acupuncture/stretching protocol versus acupuncture/stretching plus physiotherapy techniques, in patients with TTH cephalalgia. A single-blind, prospective, multicentre, randomized controlled trial was designed considering the pragmatic situation of administering such protocols and treating the 44 headache patients participating in this study. The patients were randomly assigned in 2 treatment groups (control group, n = 20, acupuncture/stretching; experimental group, n = 24, acupuncture/stretching plus physiotherapy) and completed 10 treatment sessions within 4 weeks with measurements taking place before treatment, after the fifth treatment and after the 10th treatment. The mechanical pressure pain threshold (PPT) was considered as the main outcome measure, using a mechanical algometer to measure 7 bilateral somatic points. Acupuncture in both groups included 17-20 acupuncture points, whereas stretching was initially taught and subsequently self-administered (self-stretches), following a standardized set of movements of the cervical spine. Physiotherapy consisted of microwave diathermy and myofascial release with hands-on techniques. An improvement was noted in both groups/treatments regarding the main outcome measure PPT, all the way from the first to fifth and the 10th treatment, at all measuring sites and at all measurements in both groups (p < .001). When comparing the 2 groups, differences were noted after the 10th treatment (p < .05). In conclusion, patients with TTH headache were benefited from acupuncture and stretching but further PPT improvements were evidenced when physiotherapy hands-on techniques were added. In clinical terms, the combination of physiotherapy in the form of myofascial release and microwave diathermy with

Diathermy is known to produce a mixture of waste products including carbon monoxide. During transcervical hysteroscopic surgery, carbon monoxide might enter the circulation leading to the formation of carboxyhaemoglobin. In 20 patients scheduled for transcervical hysteroscopic resection of myoma or endometrium, carboxyhaemoglobin was measured before and at the end of the surgical procedure, and compared with levels measured in 20 patients during transurethral prostatectomy, and in 20 patients during tonsillectomy. Haemodynamic data, including ST-segment changes, were recorded. Levels of carboxyhaemoglobin increased significantly during hysteroscopic surgery from median (IQR [range]) 1.0% (0.7-1.4 [0.5-4.9])% to 3.5% (2.0-6.1 [1.3-10.3]%, p < 0.001), compared with levels during prostatectomy or tonsillectomy. Significant ST-segment changes were observed in 50% of the patients during hysteroscopic surgery. Significant correlations were observed between the increase in carboxyhaemoglobin and the maximum ST-segment change (ρ = -0.707, p < 0.01), between the increase in carboxyhaemoglobin and intravasation (ρ = 0.625; p < 0.01), and between intravasation and the maximum ST-segment change (ρ = -0.761; p < 0.01). The increased carboxyhaemoglobin levels during hysteroscopic surgery appear to be related to the amount of intravasation and this could potentially be a contributing factor to the observed ST-segment changes. © 2014 The Association of Anaesthetists of Great Britain and Ireland.

Klippel-Feil syndrome (KFS) is associated with numerous craniofacial abnormalities but rarely with skull base tumor formation. We report an unusual and dramatic case of a symptomatic, mature skull base teratoma in an adult patient with KFS, with extension through the basisphenoid to obstruct the nasopharynx. This benign lesion was associated with midline palatal and cerebral defects, most notably pituitary and vertebrobasilar arteriolar duplications. A multidisciplinary workup and a complete endoscopic, transnasal surgical approach between otolaryngology and neurosurgery were undertaken. Out of concern for vascular control of the fibrofatty dense tumor stalk at the skull base and need for complete teratoma resection, we successfully employed a tissue resection tool with combined ultrasonic and bipolar diathermy to the tumor pedicle at the sphenoid/clivus junction. No CSF leak or major hemorrhage was noted using this endonasal approach, and no concerning postoperative sequelae were encountered. The patient continues to do well now 3 years after tumor extirpation, with resolution of all preoperative symptoms and absence of teratoma recurrence. KFS, teratoma biology, endocrine gland duplication, and the complex considerations required for successfully addressing this type of advanced skull base pathology are all reviewed herein.

The aim of this study was to compare laser palatoplasty with uvulectomy with punctate palatal diathermy as treatment modalities for snoring. The study design was a prospective, single-blind, randomized-controlled trial. Eighty-three patients entered the trial. After a mean follow-up period of more than 18 months there was no statistically significant difference between the two groups regarding the patient perception of benefit from surgery or the subjective improvement in snoring. However, there was a statistically significant difference in the degree of pain in the immediate postoperative period (mean difference = 22.14, 95% CI = 7.98-36.31, P = 0.003), with the pain being worse in the laser palatoplasty group. Relative risk of complications for laser palatoplasty was 1.42 (95% CI = 0.93-2.17). The snoring scores and Glasgow Benefit Inventory scores decreased with time in both the groups but there was no statistically significant difference between the two groups.

The purpose of this study was to compare the effectiveness of laparoscopic ovarian diathermy (LOD) vs clomiphene citrate (CC) plus metformin in infertile patients with CC-resistant polycystic ovary syndrome (PCOS). Fifty primary infertile patients with CC-resistant PCOS were assigned randomly to receive LOD followed by a 6-month observation (group A) or 6-cycle course of CC plus metformin (group B). Reproductive and safety outcomes were analyzed. No significant difference between 2 groups in pregnancy (15/92 women [16.3%] vs 14/107 women [13.1%]; P = .521) and live-birth (13/92 women [14.1%] vs 12/107 women [11.2%]; P = .536) rates per cycle was observed. With the use of a Cox regression analysis, patients under medical treatment, compared with patients who received surgical treatment, had a relative risk of pregnancy of 1.2 (95% confidence interval, 0.61-2.44; P = .582) and a relative risk of live-birth of 1.4 (95% confidence interval, 0.63-2.96; P = .425). LOD and CC plus metformin seem to be 2 effective approaches to treat infertility in patients with CC-resistant PCOS. Copyright 2010 Mosby, Inc. All rights reserved.

Pediatric ophthalmologists increasingly recognize that the ideal site for intraocular lens (IOL) implantation is in the bag for aphakic eyes, but it is always very difficult via conventional technique. We conducted a prospective case series study to investigate the success rate and clinical outcomes of capsular bag reestablishment and in-the-bag IOL implantation via secondary capsulorhexis with radiofrequency diathermy (RFD) in pediatric aphakic eyes, in which twenty-two consecutive aphakic pediatric patients (43 aphakic eyes) enrolled in the Childhood Cataract Program of the Chinese Ministry of Health were included. The included children underwent either our novel technique for secondary IOL implantation (with RFD) or the conventional technique (with a bent needle or forceps), depending on the type of preoperative proliferative capsular bag present. In total, secondary capsulorhexis with RFD was successfully applied in 32 eyes (32/43, 74.4%, age 5.6±2.3 years), of which capsular bag reestablishment and in-the-bag IOL implantation were both achieved in 30 eyes (30/43, 70.0%), but in the remaining 2 eyes (2/32, 6.2%) the IOLs were implanted in the sulcus with a capsular bag that was too small. Secondary capsulorhexis with conventional technique was applied in the other 11 eyes (11/43, 25.6%, age 6.9±2.3 years), of which capsular bag reestablishment and in-the-bag IOL implantation were both achieved only in 3 eyes(3/43, 7.0%), and the IOLs were implanted in the sulcus in the remaining 8 eyes. A doughnut-like proliferative capsular bag with an extensive Soemmering ring (32/43, 74.4%) was the main success factor for secondary capsulorhexis with RFD, and a sufficient capsular bag size (33/43, 76.7%) was an additional factor in successful in-the-bag IOL implantation. In conclusion, RFD secondary capsulorhexis technique has 70% success rate in the capsular bag reestablishment and in-the-bag IOL implantation in pediatric aphakic eyes, particularly effective in cases with

To compare the effect of combined metformin and clomiphene citrate (CC) with laparoscopic ovarian diathermy (LOD) meant for ovulation induction in CC-resistant women with polycystic ovary syndrome (PCOS). Two-hundred and eighty-two anovulatory women with CC-resistant PCOS were selected in this randomized controlled trial. Patients (n = 138) received combined metformin-CC for up to six cycles or underwent LOD (n = 144) with six months follow up. The outcome measures were: ovulation rate, midcycle endometrial thickness, pregnancy and miscarriage rates. Ovulation occurred in 386/576 cycles (67%) in the combined metformin-CC group and 381/558 cycles (68.2%) in LOD group without a significant difference between the groups. Resumption of regular menstruation was similar in both groups. A significant increase in midcycle endometrial thickness was observed in the combined metformin-CC group (9.2 ± 1.2 mm vs 7.6 ± 1.1 mm) (P < 0.05). The pregnancy rate was similar in both groups (15.4% vs 17%), and there were no statistically significant differences regarding the miscarriage rate between both groups. Four twin pregnancies occurred in the metformin-CC group. No ovarian hyperstimulation occurred in either group. Combined metformin-CC and LOD are equally effective for inducing ovulation and achieving pregnancy in CC-resistant PCOS patients. © 2010 The Authors.

Electromagnetic fields used in physiotherapeutic treatment affect not only patients, but also physiotherapists, patients not undergoing treatment and electronic medical equipment. The aim of the work was to study the parameters of the electromagnetic fields of physiotherapeutic devices with respect to requirements regarding the protection of electronic devices, including medical implants, against electromagnetic intererence, and the protection of the general public (patients not undergoing treatment and bystanders), as well as medical personnel, against the health hazards caused by electromagnetic exposure. The spatial distribution of electric and magnetic field strength was investigated near 3 capacitive short-wave and 3 long-wave diathermies and 3 ultrasound therapy units, as along with the capacitive electric currents caused by electromagnetic field interaction in the upper limbs of the physiotherapists operating these devices. The physiotherapists' exposure to electromagnetic fields depends on the spatial organisation of the workspace and their location during treatment. Electric fields able to interfere with the function of electronic medical implants and in whic anyone not undergoing treatment should not be present were measured up to 150-200 cm away from active applicators of short-wave diathermy, and up to 40-45 cm away from long-wave diathermy ones. Electric fields in which workers should not be present were measured up to 30-40 cm away from the applicators and cables of active short-wave diathermy devices. A capacitive electric current with a strength exceeding many times the international recommendations regarding workers protection was measured in the wrist while touching applicators and cables of active short-wave diathermy devices. The strongest environmental electromagnetic hazards occur near short-wave diathermy devices, and to a lesser degree near long-wave diathermy devices, but were not found near ultrasound therapy units.

Hemorrhoidectomy is considered the most efficient method to treat hemorrhoids of III and IV grades. The aim of this study was to compare conventional diathermy hemorrhoidectomy and radiofrequency hemorrhoidectomy based on a large series of patients. Between June 2001 and June 2014, 1000 patients have been treated with radiofrequency hemorrhoidectomy (group A) and 500 patients have been treated with diathermy (group B) as a day-case procedure. Operating time, postoperative pain score, hospital stay, early and late postoperative complications, wound healing time and time to return to normal activities were assessed. The mean follow-up was seven years. The mean operating time for radiofrequency hemorrhoidectomy was shorter than diathermy but not significantly. Patients treated with radiofrequency had significantly less postoperative pain (measured on a Visual Analogue Scale; P=0.001), a shorter wound healing time, less time off work and postoperative complications (P=0.001) than patients who had diathermy. Neither wound healing nor mean hospital stay (day-case surgery) was significantly different. Radiofrequency hemorrhoidectomyis a valid alternative to the conventional diathermy technique, due to the reduction of operative time, postoperative pain, early and late complication rate.

Laparoscopic ovarian diathermy (LOD) is currently accepted as a successful second-line treatment for ovulation induction (OI) in clomiphene citrate (CC)-resistant women with polycystic ovary syndrome (PCOS). The aim of this study was to test the hypothesis that LOD may be superior to CC as a first-line treatment. The study included 72 anovulatory women with PCOS who were randomized to LOD (n = 36) or CC (n = 36). Women who remained anovulatory after LOD were offered CC. Similarly, women receiving CC who failed to ovulate or conceive were offered LOD. Pregnancy rates were compared between the two groups using chi(2) and odds ratio with 95% confidence interval (OR, 95% CI). After randomization, six women conceived before starting treatment and another patient postponed treatment. The remaining 65 women received the treatment (33 underwent LOD and 32 received CC). After the primary treatment, more pregnancies (44%) occurred in women receiving CC than in those undergoing LOD (27%), although the difference did not reach statistical significance [P = 0.13, OR 2.1 (0.7 - 5.8)]. After adding the second treatment, the pregnancy rate was still higher, but to a less extent, in the CC group [63% versus 52%, P = 0.2, OR 1.6 (0.6 - 4.2)]. LOD is not superior to CC as a first-line method of OI in women with PCOS. The trial is registered with ClinicalTrials.gov with an identifier number NCT00220545.

We present our experience in managing 3 children with third branchial pouch anomalies and propose a minimally invasive management algorithm avoiding open neck surgery. Retrospective case review of 3 patients including demographics, mode of presentation, investigations, management and complications. Three children, two male and one female of mean age 9.6 years presented with painful left anterior neck swelling. Axial neck imaging showed a superficial abscess with air locules and a sinus tract leading towards the left pharynx. Diagnosis was confirmed by endoscopic examination of the pyriform fossa revealing a sinus opening. Two patients underwent open excision; one combined with diathermy to the sinus opening. The last patient was diagnosed at his initial presentation and managed with endoscopic diathermy of the sinus opening combined with percutaneous needle aspiration of the neck abscess at the same sitting. One patient had two recurrences, the first after initial open surgery and the second after the first cautery. Two patients developed temporary hoarseness after the procedure, which resolved within two weeks. All patients were free from recurrences at follow-up. Introduction of the technique of endoscopic diathermy to the pyriform fossa sinus opening in children with third branchial pouch anomalies has revolutionised their management avoiding open and potentially morbid surgery. Our algorithm takes this further by advocating percutaneous needle aspiration of the infective component and performing diathermy to the sinus opening at the first presentation.

Does unilateral volume-adjusted laparoscopic diathermy increase the chances of ovulation in women with polycystic ovary syndrome (PCOS)? Although unilateral laparoscopic ovarian drilling (ULOD) using adjusted thermal doses was more efficient than bilateral laparoscopic ovarian drilling (BLOD) using fixed doses, the chances of ovulation were improved in patients irrespective of the technique used. The adjustment of the thermal dose to ovarian volume in BLOD increases ovulation and pregnancy rates compared with fixed-dose treatment, but BLOD causes the formation of adhesions, particularly on the left ovary, and increases the risk of damage to ovarian tissue. In contrast, ULOD with a fixed thermal dose minimizes the risk of ovarian tissue damage, and can increase the activity in both right and left ovaries, although this varies in humans and in other species. This prospective, longitudinal, study, between September 2009 and January 2013, included 96 infertile women with PCOS who were unresponsive to clomiphene citrate treatment and had underwent either ULOD or BLOD. After surgery, the groups were followed up for 6 months to assess ovulatory response. Patients were assigned to two groups; one group underwent laparoscopic ovarian drilling of the right ovary alone, while both ovaries were treated in the second group. The ULOD group (n = 49) received thermal doses adjusted to the volume of the right ovary (60 J/cm³). The BLOD group (n = 47) received fixed doses of 600 J per ovary, regardless of its volume. The two treatment groups were matched by the number of participants, age and baseline parameters. The ovulation rate during the first menstrual cycle after LOD was significantly higher in the ULOD group than in the BLOD group [73 versus 49%; absolute risk reduction (ARR), -0.25; 95% confidence interval (CI), -0.44 to -0.03; P = 0.014]. Treatment with ULOD on the right ovary significantly increased the chances of ovulation in patients with a larger right ovary compared

The purpose of this study was to assess the level of skill of laparoscopic surgeons in electrosurgery. Subjects were asked to complete a practical diathermy station and a written test of electrosurgical knowledge. Tests were held in teaching and non-teaching hospitals. Twenty specialists in obstetrics and gynaecology were randomly selected and tested on the Monash University gynaecological laparoscopic pelvi-trainer. Twelve candidates were consultants with 9-28 years of practice in operative laparoscopy, and 8 were registrars with up to six years of practice in operative laparoscopy. Seven consultants and one registrar were from rural Australia, and three consultants were from New Zealand. Candidates were marked with checklist criteria resulting in a pass/fail score, as well as a weighted scoring system. We retested 11 candidates one year later with the same stations. No improvement in electrosurgery skill in one year of obstetric and gynaecological practice. No candidate successfully completed the written electrosurgery station in the initial test. A slight improvement in the pass rate to 18% was observed in the second test. The pass rate of the diathermy station dropped from 50% to 36% in the second test. The study found ignorance of electrosurgery/diathermy among gynaecological surgeons. One year later, skills were no better.

Electrical interference in non-competitive pacemakers

Patients with 41 implanted non-competitive pacemakers were investigated. A variety of domestic electrical equipment, a motor-car, and a physiotherapy diathermy apparatus were each operated in turn at various ranges from the patient. Interference effects on pacemaker function were assessed on the electrocardiograph. Medtronic demand 5841 pacemakers were stopped by diathermy while Cordis Ectocor pacemakers developed a fast discharge rate. Cordis triggered pacemakers (both Atricor and Ectocor) were sensitive to interference from many items of domestic equipment and the motor car. The Elema EM153 ran at an increased rate when an electric razor was running close to the pacemaker. The Devices demand 2980 and the Medtronic demand 5841 were not affected by the domestic equipment tested. The significance of interference effects is discussed in relation to pacemaker design.

Cataract after exposure to non-ionizing radiant energy.

PubMed Central

Zaret, M M; Snyder, W Z; Birenbaum, L

1976-01-01

The case histories of two individuals exposed to thermal radiation emitted from an electric oven and range were presented. In one patient, earlier exposure to medical diathermy appears to have initiated delayed or late-appearing, capsular cataracts. Instead of the anticipated slow progression, the cataractogenesis was accelerated following recent, repeated exposure to the intense, infrared radiation. In the other patient, exposed solely to infrared radiation, a chorioretinal lesion indistinguishable from the type characteristically secondary to repeated, thermal radiation was observed. More recently, the earliest sign of thermal radiation cataractogenesis, capsular opacification, has become evident. The widespread availability of radiant energy sources such as diathermy machines, microwave ovens, and electric ovens and ranges makes it imperative to examine carefully any possible hazards that may result from their use. With this in mind, radiant energy should be considered in the differential diagnosis of cataractogenesis. Images PMID:990233

Does circumpatellar electrocautery improve the outcome after total knee replacement?: a prospective, randomised, blinded controlled trial.

PubMed

The incidence of anterior knee pain following total knee replacement (TKR) is reported to be as high as 49%. The source of the pain is poorly understood but the soft tissues around the patella have been implicated. In theory circumferential electrocautery denervates the patella thereby reducing efferent pain signals. However, there is mixed evidence that this practice translates into improved outcomes. We aimed to investigate the clinical effect of intra-operative circumpatellar electrocautery in patients undergoing TKR using the LCS mobile bearing or Kinemax fixed bearing TKR. A total of 200 patients were randomised to receive either circumpatellar electrocautery (diathermy) or not (control). Patients were assessed by visual analogue scale (VAS) for anterior knee pain and Oxford knee score (OKS) pre-operatively and three months, six months and one year post-operatively. Patients and assessors were blinded. There were 91 patients in the diathermy group and 94 in the control. The mean VAS improvement at one year was 3.9 in both groups (control; -10 to 6, diathermy; -9 to 8, p < 0.001 in both cases, paired, two-tailed t-test). There was no significant difference in VAS between the groups at any other time. The mean OKS improvement was 17.7 points (0 to 34) in the intervention group and 16.6 (0 to 42) points in the control (p = 0.36). There was no significant difference between the two groups in OKS at any other time. We found no relevant effect of patellar electrocautery on either VAS anterior knee pain or OKS for patients undergoing LCS and Kinemax TKR.

2016-01-01

A systematic review on laryngopyoceles across Ovid, PubMed, and Google Scholar database was conducted. A total of 61 papers published between 1952 and 2015 were found. Of these, 23 cases written in English, which described the number of cases, surgical approaches, resort to tracheostomy, complications, and outcomes, were shortlisted. Four cases of laryngopyoceles were managed endoscopically using a cold instrument, microdebrider, or laser. Eighteen cases were operated via an external approach, and 1 case applied both approaches. One of 4 endoscopic and 10 of 18 external approaches involved tracheostomy. The present study aimed to report a case of large mixed laryngopyocele that was successfully drained and marsupialized endoscopically using suction diathermy without requiring tracheostomy. Management using suction diathermy for excision and marsupialization of a laryngopyocele has never been reported and can be recommended as a feasible method due to its widespread availability. In the presence of a large laryngopyocele impeding the airway, tracheostomy may be averted in a controlled setting. None specified.

Treatment of Ureterointestinal Anastomotic Strictures by Diathermal or Cryoplastic Dilatation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Orsi, Franco; Penco, Silvia; Matei, Victor

2007-09-15

Background. Ureterointestinal anastomotic strictures (UAS) complicate 10-15% of surgeries for urinary diversion and are the main cause of deterioration in renal function. Treatments are surgical revision, management with autostatic stent, balloon dilatation, endoscopic incision, and percutaneous transrenal diathermy (Acucise). A new option is cryoplastic dilatation (Polar-Cath). Purpose. To assess the feasibility, complications, and preliminary results of UAS treatment using the Acucise and Polar-Cath systems. Methods. Nineteen UAS, diagnosed by ultrasonography or computed tomography and sequential renal scintigraphy, occurred in 15 cancer patients after radical cystectomy and urinary diversion. Fifteen were managed with balloon diathermy and 4 by balloon cryoplasty inmore » a three-stage procedure-percutaneous nephrostomy, diathermal or cryoplastic dilatation, and transnephrostomic control with nephrostomy removal-each separated by 15 days. All patients gave written informed consent. Results. Dilatations were successful in all cases. The procedure is simple and rapid (about 45 min) under fluoroscopic control and sedation. Procedural complications occurred in 1 (5%) patient with UAS after Wallace II uretero-ileocutaneostomy: a common iliac artery lesion was induced by diathermal dilatation, evident subsequently, and required surgical repair. Patency with balloon diathermy was good, with two restenoses developing over 12 months (range 1-22) of follow-up. With balloon cryoplastic dilatation, one restenosis developed in the short term; follow-up is too brief to assess the long-term efficacy. Conclusion. Our short-term results with diathermal and cryoplastic dilatation to resolve UAS are good. If supported by longer follow-up, the techniques may be considered as first-choice approaches to UAS. Surgery should be reserved for cases in which this minimally invasive technique fails.« less

Enterobius vermicularis infestation of the appendix and management at the time of laparoscopic appendectomy: case series and literature review.

PubMed

Enterobius vermicularis infestation of the vermiform appendix can mimic appendicitis. In these cases, laparoscopic appendicectomy runs a risk of contamination of the peritoneal cavity with worms. We reviewed our practice to suggest changes that will reduce the release of worms and propose methods to use in case contamination occurs. 498 patients underwent appendicectomy over a sixty-three month period. 13 (2.6%) patients had confirmed E. vermicularis on histology of whom 6 (46%) were performed laparoscopically. These patients' case notes were retrospectively reviewed. The worms were noted intra-operatively during the laparoscopic appendectomies. In 2 cases, where peritoneal cavity contamination with worms occurred, they were dealt with careful diathermy or endoscopic suction. In the other cases, contamination was avoided by simple measures including division of the appendix in a staggered manner whilst maintaining traction, removal of worms using endoscopic suction or diathermy and quick transfer to a specimen bag. We highlight that the symptoms of appendicitis can be due to Enterobius vermicularis infestation without any histological evidence of acute inflammation. Surgeons need to be aware of this possibility during laparoscopic appendicectomy and simple techniques can minimise the risk of contamination. It also enables early diagnosis and treatment without awaiting histological findings. Copyright © 2010 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

To evaluate an interlaced triple procedure that involved penetrating keratoplasty (PKP), extracapsular cataract extraction (ECCE) using diathermy capsulotomy, and nonopen-sky intraocular lens (IOL) implantation.This retrospective study involved data from 34 patients who were diagnosed with severe corneal opacities and cataracts. These patients were divided into an interlaced procedure group (21 patients) and a traditional procedure group (13 patients). In the interlaced group, the method of continuous curvilinear capsulorhexis (CCC) was completed via diathermy capsulotomy. The donor corneal button was sutured at 8 positions (at equal intervals) using 10-0 nylon sutures, and the IOL was inserted into the capsular bag using a closed anterior chamber approach at the 10:30 to 12 o'clock positions between the sutures. In the traditional group, CCC was completed using side-port capsular forceps, and the IOL was implanted using an open anterior chamber approach.In the interlaced group, the CCC, open-sky, and total operation times were significantly shorter than in the traditional group (P < .05). Neither the best-corrected visual acuity (BCVA) nor corneal endothelial cell density was significantly different between the groups at 1 and 6 months after the operation.This interlaced triple procedure for the treatment of corneal diseases with cataracts appears to be feasible and practical.

[Occupational exposure of physical therapists to electric and magnetic fields and the efficacy of Faraday cages].

PubMed

2011-10-01

Measure physical therapists' exposure to the electric and magnetic fields produced by 17 shortwave diathermy devices in physical therapy clinics in the city of Presidente Prudente, São Paulo State, Brazil. Compare the observed values with the exposure levels recommended by the International Commission on Non-ionizing Radiation Protection (ICNIRP). Observe the efficacy of Faraday cages as a means of protecting physical therapists from exposure to oscillating electric and magnetic fields. Electric and magnetic field measurements were taken at four points during actual physical therapy sessions: in proximity to the operator's pelvis and head, the devices' electrical cables, and the electrodes. The measuring equipment was a Wandel & Goltermann EMR-200. The values obtained in proximity to the electrodes and cables were 10 to 30 times higher than ICNIRP's recommended occupational reference levels. In the shortwave diathermy treatment rooms with Faraday cages, the fields were even higher than in treatment rooms not so equipped-principally the magnetic field, where the values were more than 100 times higher than the ICNIRP exposure limit. The electric and magnetic field intensities obtained in this study are generally above the exposure levels recommend in ICNIRP standards. It was also observed that the Faraday cage offers physical therapists no protection, and instead, increases their level of exposure.

Robotic treatment of a type 2 calyceal diverticulum in a child: is suture closure and marsupialisation enough for a good outcome?

PubMed

Sripathi, V; Mitra, Aparajita; Padankatti, Rajiv L; Ganesan, T

2017-10-27

Calyceal diverticula in children are rare and 20% eventually become symptomatic. Following the use of laparoscopic or endoscopic treatments, 85% of children report symptomatic relief. However, complete radiological resolution is seen only in three-fourths of the laparoscopic group and a quarter of those treated via endoscopy. Diathermy ablation of the lining and/or prolonged double J stenting has not altered this outcome. The robotic approach is superior to the other two techniques as the leak can be clearly identified and securely suture ligated. We believe that this is the third published report of the successful closure of a calyceal diverticulum in a child using robotic assistance. A ten-year-old boy presented with severe pain in the right flank and a palpable renal swelling. Retrograde injection of contrast outlined a large exophytic calyceal diverticulum (type 2) in the lower pole. Robotic assistance allowed precise suture closure of the neck as well as partial marsupialisation of the diverticulum. The child was discharged within 48 h and remains symptom free 18 months later. Calyceal diverticula are rare but technically challenging entities. We have shown a good outcome with only suture closure of the leak. Diathermy ablation of the lining and prolonged internal stenting were avoided.

Given the dynamic nature of modern surgical education, determining factors that may improve the efficiency of laparoscopic training is warranted. The objective of this study was to analyze whether perceptual, visuo-spatial, or psychomotor aptitude are related to the amount of training required to reach specific performance-based goals on a virtual reality surgical simulator. Sixteen MS4 medical students participated in an elective skills course intended to train laparoscopic skills. All were tested for perceptual, visuo-spatial, and psychomotor aptitude using previously validated psychological tests. Training involved as many instructor-guided 1-hour sessions as needed to reach performance goals on a custom designed MIST-VR manipulation-diathermy task (Mentice AB, Gothenberg, Sweden). Thirteen subjects reached performance goals by the end of the course. Two were excluded from analysis due to previous experience with the MIST-VR (total n = 11). Perceptual ability (r = -0.76, P = 0.007) and psychomotor skills (r = 0.62, P = 0.04) significantly correlated with the number of trials required. Visuo-spatial ability did not significantly correlate with training duration. The number of trials required to train subjects to performance goals on the MIST-VR manipulation diathermy task is significantly related to perceptual and psychomotor aptitude.

Occupational exposure to electromagnetic fields from medical sources

STAM, Rianne; YAMAGUCHI-SEKINO, Sachiko

2017-01-01

High exposures to electromagnetic fields (EMF) can occur near certain medical devices in the hospital environment. A systematic assessment of medical occupational EMF exposure could help to clarify where more attention to occupational safety may be needed. This paper seeks to identify sources of high exposure for hospital workers and compare the published exposure data to occupational limits in the European Union. A systematic search for peer-reviewed publications was conducted via PubMed and Scopus databases. Relevant grey literature was collected via a web search. For each publication, the highest measured magnetic flux density or internal electric field strength per device and main frequency component was extracted. For low frequency fields, high action levels may be exceeded for magnetic stimulation, MRI gradient fields and movement in MRI static fields. For radiofrequency fields, the action levels may be exceeded near devices for diathermy, electrosurgery and hyperthermia and in the radiofrequency field inside MRI scanners. The exposure limit values for internal electric field may be exceeded for MRI and magnetic stimulation. For MRI and magnetic stimulation, practical measures can limit worker exposure. For diathermy, electrosurgery and hyperthermia, additional calculations are necessary to determine if SAR limits may be exceeded in some scenarios. PMID:29109357

The use of electrotherapy has been part of physical therapy treatment for the past few decades. There have been numerous modalities used such as TENS, interferential, diathermy, magnetic therapy, ultrasound, laser and surface electromyography to name a few. There has been an upsurge in the past decade of new and innovative modalities. There needs to be extensive research on each of these electrotherapy devices to determine the proper use of each device.

Surgical smoke - a health hazard in the operating theatre: a study to quantify exposure and a survey of the use of smoke extractor systems in UK plastic surgery units.

PubMed

Hill, D S; O'Neill, J K; Powell, R J; Oliver, D W

2012-07-01

Surgeons and operating theatre personnel are routinely exposed to the surgical smoke plume generated through thermal tissue destruction. This represents a significant chemical and biological hazard and has been shown to be as mutagenic as cigarette smoke. It has previously been reported that ablation of 1 g of tissue produces a smoke plume with an equivalent mutagenicity to six unfiltered cigarettes. We studied six human and 78 porcine tissue samples to find the mass of tissue ablated during 5 min of monopolar diathermy. The total daily duration of diathermy use in a plastic surgery theatre was electronically recorded over a two-month period. On average the smoke produced daily was equivalent to 27-30 cigarettes. Our survey of smoke extractor use in UK plastic surgery units revealed that only 66% of units had these devices available. The Health and Safety Executive recommend specialist smoke extractor use, however they are not universally utilised. Surgical smoke inhalation is an occupational hazard in the operating department. Our study provides data to quantify this exposure. We hope this evidence can be used together with current legislation to make the use of surgical smoke extractors mandatory to protect all personnel in the operating theatre.

To assess face validity, construct validity and the training benefits of a virtual reality TURP simulator. 11 novices (no TURP experience) and 7 experts (>200 TURP's) completed a virtual reality median lobe prostate resection task on the TURPsim™ (Simbionix USA Corp., Cleveland, OH). Performance indicators (percentage of prostate resected (PR), percentage of capsular resection (CR) and time diathermy loop active without tissue contact (TAWC) were recorded via the TURPsim™ and compared between novices and experts to assess construct validity. Verbal comments provided by experts following task completion were used to assess face validity. Repeated attempts of the task by the novices were analysed to assess the training benefits of the TURPsim™. Experts resected a significantly greater percentage of prostate per minute (p < 0.01) and had significantly less active diathermy time without tissue contact (p < 0.01) than novices. After practice, novices were able to perform the simulation more effectively, with significant improvement in all measured parameters. Improvement in performance was noted in novices following repetitive training, as evidenced by improved TAWC scores that were not significantly different from the expert group (p = 0.18). This study has established face and construct validity for the TURPsim™. The potential benefit in using this tool to train novices has also been demonstrated.

Multi-Stream Saline-Jet Dissection Using a Simple Irrigation System Defines Difficult Tissue Planes

PubMed Central

Ng, Philip CH

2010-01-01

Introduction: Single-stream hydro-jet dissection is increasingly used in various laparoscopic procedures, but its use requires special equipment. We describe a simple method for using an irrigation system for saline-jet tissue dissection as a useful adjunct prior to adhesiolysis. Material and Methods: Intraabdominal adhesions prolong laparoscopic procedures, because tissue planes are difficult to identify. We performed multi-jet saline dissection (MSSJ) between 2000 and 2009 in more than 500 patients during laparoscopy involving hernias, gallbladders, appendices, and intestinal obstructions. We use a standard suction irrigation probe, which is attached to a 1-liter saline bag with an inflatable cuff around to create a pressure of 250mm Hg to 300mm Hg. In effect, this is the standard setup generally used for irrigation. After using saline dissection, tissue planes can be better defined and the structures can then be separated. Result and Discussion: Using this method, we have successfully identified tissue planes in spite of dense adhesions, and our conversion rates to open have been reduced dramatically. This method is relatively safer than other modalities of tissue dissection, such as diathermy, ultrasonic, blunt or sharp dissection. The disadvantage is that with tissues saturated with saline it becomes more difficult to use diathermy hemostasis. Care has to be exercised in monitoring the temperature and volume of the fluid used.

Non-ionizing radiation at 2.45 GHz may modify the morphology and expression of genes that codify heat shock proteins (HSP) in the thyroid gland. Diathermy is the therapeutic application of non-ionizing radiation to humans for its beneficial effects in rheumatological and musculo-skeletal pain processes. We used a diathermy model on laboratory rats subjected to maximum exposure in the left front leg, in order to study the effects of radiation on the nearby thyroid tissue. Fifty-six rats were individually exposed once or repeatedly (10 times in two weeks) for 30 min to 2.45 GHz radiation in a commercial chamber at different non-thermal specific absorption rates (SARs), which were calculated using the finite difference time domain technique. We used immunohistochemistry methods to study the expression of HSP-90 and morphological changes in thyroid gland tissues. Ninety minutes after radiation with the highest SAR, the central and peripheral follicles presented increased size and the thickness of the peripheral septa had decreased. Twenty-four hours after radiation, only peripheral follicles radiated at 12 W were found to be smaller. Peripheral follicles increased in size with repeated exposure at 3 W power. Morphological changes in the thyroid tissue may indicate a glandular response to acute or repeated stress from radiation in the hypothalamic–pituitary–thyroid axis. Further research is needed to determine if the effect of this physical agent over time may cause disease in the human thyroid gland. PMID:25649190

A randomised controlled comparison of haemostatic efficacy of mechanical, injection, and thermal methods of haemostasis was undertaken using canine mesenteric vessels to test the hypothesis that mechanical methods of haemostasis are more effective in controlling haemorrhage than injection or thermal methods. The diameter of arteries in human bleeding ulcers measures up to 3.45 mm; mesenteric vessels up to 5 mm were therefore studied. Mesenteric vessels were randomised to treatment with injection sclerotherapy (adrenaline and ethanolamine), bipolar diathermy, or mechanical methods (band, clips, sewing machine, endoloops). The vessels were severed and haemostasis recorded. Injection sclerotherapy and clips failed to stop bleeding from vessels of 1 mm (n = 20) and 2 mm (n = 20). Bipolar diathermy was effective on 8/10 vessels of 2 mm but failed on 3 mm vessels (n = 5). Unstretched elastic bands succeeded on 13/15 vessels of 2 mm but on only 3/10 vessels of 3 mm. The sewing machine achieved haemostasis on 8/10 vessels of 4 mm but failed on 5 mm vessels (n = 5); endoloops were effective on all 5 mm vessels (n = 5). Only mechanical methods were effective on vessels greater than 2 mm in diameter. Some mechanical methods (banding and clips) were less effective than expected and need modification. Thermal and (effective) mechanical methods were significantly (p < 0.01) more effective than injection sclerotherapy. The most effective mechanical methods were significantly more effective (p < 0.01) than thermal or injection on vessels greater than 2 mm.

To analyze the relationship between visuospatial ability and simulated laparoscopy performed by consultants in obstetrics and gynecology (OBGYN). This was a prospective cohort study carried out at two community hospitals in Sweden. Thirteen consultants in obstetrics and gynecology were included. They had previously independently performed 10-100 advanced laparoscopies. Participants were tested for visuospatial ability by the Mental Rotations Test version A (MRT-A). After a familiarization session and standardized instruction, all participants subsequently conducted three consecutive virtual tubal occlusions followed by three virtual salpingectomies. Performance in the simulator was measured by Total Time, Score and Ovarian Diathermy Damage. Linear regression was used to analyze the relationship between visuospatial ability and simulated laparoscopic performance. The learning curves in the simulator were assessed in order to interpret the relationship with the visuospatial ability. Visuospatial ability correlated with Total Time (r=-0.62; p=0.03) and Score (r=0.57; p=0.05) in the medium level of the virtual tubal occlusion. In the technically more advanced virtual salpingectomy the visuospatial ability correlated with Total Time (r=-0.64; p=0.02), Ovarian Diathermy Damage (r=-0.65; p=0.02) and with overall Score (r=0.64; p=0.02). Visuospatial ability appears to be related to the performance of gynecological laparoscopic procedures in a simulator. Testing visuospatial ability might be helpful when designing individual training programs. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Physician perceptions of the value of physical modalities in the treatment of musculoskeletal disease.

Rush, P J; Shore, A

1994-06-01

We randomly surveyed 100 specialists in rehabilitation medicine and 100 rheumatologists concerning their perceptions of the value of 11 different physical modalities--cold, active and passive exercise, interferential current, laser, magnetotherapy, microwave, shortwave diathermy, traction, ultrasound and transcutaneous nerve stimulation in the treatment of seven different musculoskeletal conditions--acute arthritis, joint contracture, neck pain, back pain, tendinitis, reflex sympathetic dystrophy and frozen shoulder. There were significant differences in the perceived benefits of modalities which varied by modality and condition. Overall, rehabilitation medicine specialists regarded modalities to be helpful more often than rheumatologists (P < 0.001).

The Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR) has been well validated as a training device for laparoscopic skills. It has been demonstrated that training to a level of proficiency on the simulator significantly improves operating room performance of laparoscopic cholecystectomy. The purpose of this project was to obtain a national standard of proficiency using the MIST-VR based on the performance of experienced laparoscopic surgeons. Surgeons attending the Society of American Gastrointestinal Endoscopic Surgeons (SAGES) 2004 Annual Scientific Meeting who had performed more than 100 laparoscopic procedures volunteered to participate. All the subjects completed a demographic questionnaire assessing laparoscopic and MIST-VR experience in the learning center of the SAGES 2004 meeting. Each subject performed two consecutive trials of the MIST-VR Core Skills 1 program at the medium setting. Each trial involved six basic tasks of increasing difficulty: acquire place (AP), transfer place (TP), traversal (TV), withdrawal insert (WI), diathermy task (DT), and manipulate diathermy (MD). Trial 1 was considered a "warm-up," and trial 2 functioned as the test trial proper. Subject performance was scored for time, errors, and economy of instrument movement for each task, and a cumulative total score was calculated. Trial 2 data are expressed as mean time in seconds in Table 2. Proficiency levels for laparoscopic skills have now been established on a national scale by experienced laparoscopic surgeons using the MIST-VR simulator. Residency programs, training centers, and practicing surgeons can now use these data as guidelines for performance criterion during MIST-VR skills training.

Ankle joint equinus, or restricted dorsiflexion range of motion (ROM), has been linked to a range of pathologies of relevance to clinical practitioners. This systematic review and meta-analysis investigated the effects of conservative interventions on ankle joint ROM in healthy individuals and athletic populations. Keyword searches of Embase, Medline, Cochrane and CINAHL databases were performed with the final search being run in August 2013. Studies were eligible for inclusion if they assessed the effect of a non-surgical intervention on ankle joint dorsiflexion in healthy populations. Studies were quality rated using a standard quality assessment scale. Standardised mean differences (SMDs) and 95% confidence intervals (CIs) were calculated and results were pooled where study methods were homogenous. Twenty-three studies met eligibility criteria, with a total of 734 study participants. Results suggest that there is some evidence to support the efficacy of static stretching alone (SMDs: range 0.70 to 1.69) and static stretching in combination with ultrasound (SMDs: range 0.91 to 0.95), diathermy (SMD 1.12), diathermy and ice (SMD 1.16), heel raise exercises (SMDs: range 0.70 to 0.77), superficial moist heat (SMDs: range 0.65 to 0.84) and warm up (SMD 0.87) in improving ankle joint dorsiflexion ROM. Some evidence exists to support the efficacy of stretching alone and stretching in combination with other therapies in increasing ankle joint ROM in healthy individuals. There is a paucity of quality evidence to support the efficacy of other non-surgical interventions, thus further research in this area is warranted.

This study investigated the hypothesis that muscle damage would be attenuated in muscles subjected to passive hyperthermia 1 day prior to exercise. Fifteen male students performed 24 maximal eccentric actions of the elbow flexors with one arm; the opposite arm performed the same exercise 2-4 weeks later. The elbow flexors of one arm received a microwave diathermy treatment that increased muscle temperature to over 40 degrees C, 16-20 h prior to the exercise. The contralateral arm acted as an untreated control. Maximal voluntary isometric contraction strength (MVC), range of motion (ROM), upper arm circumference, muscle soreness, plasma creatine kinase activity and myoglobin concentration were measured 1 day prior to exercise, immediately before and after exercise, and daily for 4 days following exercise. Changes in the criterion measures were compared between conditions (treatment vs. control) using a two-way repeated measures ANOVA with a significance level of P < 0.05. All measures changed significantly following exercise, but the treatment arm showed a significantly faster recovery of MVC, a smaller change in ROM, and less muscle soreness compared with the control arm. However, the protective effect conferred by the diathermy treatment was significantly less effective compared with that seen in the second bout performed 4-6 weeks after the initial bout by a subgroup of the subjects (n = 11) using the control arm. These results suggest that passive hyperthermia treatment 1 day prior to eccentric exercise-induced muscle damage has a prophylactic effect, but the effect is not as strong as the repeated bout effect.

To describe a technique of corneal vessel occlusion by using electrolysis-needle cautery. A prospective case series of three patients. Corneal vessels were successfully occluded in all patients. Vessels remained occluded during the first 8 months post-cautery follow up. Two patients needed repeat cautery at 9 and 10 months respectively. Patients found the procedure comfortable. There was no post-operative induced astigmatism. The technique of ENC is simple, effective and controlled. This technique compares favorably and may prove to be more versatile than Fine Needle Diathermy in the occlusion of corneal vessels that lead to lipid keratopathy.

The length of testicular vessels is the main length-limiting factor to bring down the testes in the scrotum. Fowler and Stephen proposed the division of testicular vessels, high and as far from the testes as possible to maintain collateral blood supply, to treat high intra-abdominal testes. Cortesi introduced the diagnostic laparoscopy and Jorden first did the laparoscopic orchiopexy for nonpalpable testes. We had done Fowler-Stephen staged orchiopexy for high intra-abdominal testes, in which both stages were done laparoscopically. In total, 17 testes of 13 patients had undergone laparoscopic staged Fowler-Stephen orchiopexy. The decision to perform a staged Fowler-Stephen orchiopexy was based on the distance of the testis from the deep inguinal ring on laparoscopy. If distance was more than 2.5 cm, then we proceeded to a laparoscopic staged Fowler-Stephen orchiopexy. In the first stage, testicular vessels were cauterized by bipolar diathermy. Laparoscopic second-stage Fowler-Stephen procedure was done 6 months after the first stage. Patients were regularly followed, and the success of the procedure was assessed by the size of the testes and the position in the scrotum. Testicular vascularity was assessed by color Doppler ultrasonography. There was no testicular atrophy on second stage and on follow-up. All testes were in the scrotum with good size on follow-up. There was no complication related to laparoscopy. In cases of high intra-abdominal testes, the staged Fowler-Stephen procedure should be the procedure of choice. This procedure yields a high success rate. Transaction of vessels by bipolar diathermy is a very safe, cost-effective method.

Background and aims—A randomised controlled comparison of haemostatic efficacy of mechanical, injection, and thermal methods of haemostasis was undertaken using canine mesenteric vessels to test the hypothesis that mechanical methods of haemostasis are more effective in controlling haemorrhage than injection or thermal methods. The diameter of arteries in human bleeding ulcers measures up to 3.45 mm; mesenteric vessels up to 5 mm were therefore studied. 
Methods—Mesenteric vessels were randomised to treatment with injection sclerotherapy (adrenaline and ethanolamine), bipolar diathermy, or mechanical methods (band, clips, sewing machine, endoloops). The vessels were severed and haemostasis recorded. 
Results—Injection sclerotherapy and clips failed to stop bleeding from vessels of 1 mm (n=20) and 2 mm (n=20). Bipolar diathermy was effective on 8/10 vessels of 2 mm but failed on 3 mm vessels (n=5). Unstretched elastic bands succeeded on 13/15 vessels of 2 mm but on only 3/10 vessels of 3 mm. The sewing machine achieved haemostasis on 8/10 vessels of 4 mm but failed on 5 mm vessels (n=5); endoloops were effective on all 5 mm vessels (n=5). 
Conclusions—Only mechanical methods were effective on vessels greater than 2 mm in diameter. Some mechanical methods (banding and clips) were less effective than expected and need modification. Thermal and (effective) mechanical methods were significantly (p<0.01) more effective than injection sclerotherapy. The most effective mechanical methods were significantly more effective (p<0.01) than thermal or injection on vessels greater than 2mm.

No single treatment yet exists for pilonidal disease that has a short healing time, good cosmetic results, and a low rate of recurrence. Phenol crystal application and diathermy ablation through an endoscope have been used for the treatment of pilonidal disease, but this cohort is the first one to combine them. The purpose of this study was to examine the safety, effectiveness, and short- and long-term outcomes of crystalized phenol treatment combined with endoscopic pilonidal sinus treatment for pilonidal disease. This was a prospective cohort study. Procedures were performed in 2 hospitals by the same surgeon between February and July 2014. Twenty-three patients underwent surgical treatment for pilonidal disease. Under local anesthesia and sedation, all of the patients underwent a video-assisted diathermy ablation of the sinus cavity and the application of phenol crystals. Adverse events were recorded as a measure of safety and tolerability. Failure to heal and recurrence rate were documented and evaluated. Patients were discharged on the same day as surgery. There was no or minimal postoperative pain (mean visual analog scale score, 1.40 ± 0.95). Mean operation time was 20.43 ± 6.19 minutes, and the median return-to-work duration was 2.00 days (mean, 3.03 ± 2.95 d). Patients were followed-up for 18 to 24 months (mean, 22.00 ± 1.88 mo). No serious complications or rehospitalization were observed. No primary failure to heal or recurrence was observed. This study did not include a control group with which to compare and consisted of a relatively small number of patients. Crystalized phenol treatment combined with endoscopic pilonidal sinus treatment was safe, tolerable, and achieved fast and durable healing with no recurrence over an average of 22 months of follow-up.

OBJECTIVE--To compare the effectiveness of manipulative therapy, physiotherapy, treatment by the general practitioner, and placebo therapy in patients with persistent non-specific back and neck complaints. DESIGN--Randomised clinical trial. SETTING--Primary health care in the Netherlands. PATIENTS--256 patients with non-specific back and neck complaints of at least six weeks' duration who had not received physiotherapy or manipulative therapy in the past two years. INTERVENTIONS--At the discretion of the manipulative therapists, physiotherapists, and general practitioners. Physiotherapy consisted of exercises, massage, and physical therapy (heat, electrotherapy, ultrasound, shortwave diathermy). Manipulative therapy consisted of manipulation and mobilisation of the spine. Treatment by general practitioners consisted of drugs (for example, analgesics), advice about posture, home exercises, and (bed)rest. Placebo treatment consisted of detuned shortwave diathermy (10 minutes) and detuned ultrasound (10 minutes). MAIN OUTCOME MEASURES--Changes in severity of the main complaint and limitation of physical functioning measured on 10 point scales by a blinded research assistant and global perceived effect measured on a 6 point scale by the patients. RESULTS--Many patients in the general practitioner and placebo groups received other treatment during follow up. Improvement in the main complaint was larger with manipulative therapy (4.5) than with physiotherapy (3.8) after 12 months' follow up (difference 0.9; 95% confidence interval 0.1 to 1.7). Manipulative therapy also gave larger improvements in physical functioning (difference 0.6; -0.1 to 1.3). The global perceived effect after six and 12 months' follow up was similar for both treatments. CONCLUSIONS--Manipulative therapy and physiotherapy are better than general practitioner and placebo treatment. Furthermore, manipulative therapy is slightly better than physiotherapy after 12 months. PMID:1532760

To compare a plasma ablation device with a standard ablation device in anterior cruciate ligament (ACL) reconstruction to determine which system is superior in terms of intra-articular heat generation and diathermy efficiency. This was a prospective, randomized controlled trial. The inclusion criteria were adult patients undergoing primary ACL reconstruction. Patients were randomized preoperatively to the standard ablation group or the plasma ablation group. A thermometer was inserted into the inferior suprapatellar pouch, and the temperature, time, and duration of radiofrequency ablation were measured continually. No significant differences were found between the standard ablation system and the plasma ablation system for maximum temperature (29.77°C and 29.34°C, respectively; P = .95), mean temperature (26.16°C and 26.99°C, respectively; P = .44), minimum temperature (22.66°C and 23.94°C, respectively; P = .54), and baseline temperature (26.80°C and 27.93°C, respectively; P = .35). Similarly, no significant differences were found for operative time (82.90 minutes and 80.50 minutes, respectively; P = .72) and mean diathermy activation times (2.6 minutes for both systems; P = .90). The between-system coefficient of variation for the measured parameters ranged from 0.12% to 3.69%. No intra-articular readings above the temperature likely to damage chondrocytes were recorded. The mean irrigation fluid temperature had a significant correlation with the maximum temperature reached during the procedure (Spearman rank correlation, r = 0.87; P < .01). No difference in temperature was observed between the standard ablation and plasma ablation probes during ACL reconstruction. Temperatures did not exceed critical temperatures associated with chondrocyte death. Level I, randomized controlled trial. Copyright © 2016 The Authors. Published by Elsevier Inc.

To assess the changes in hormonal profile (serum FSH, LH, prolactin and total testosterone) following laparoscopic ovarian drilling (LOD) in patients with polycystic ovarian syndrome. Fifty patients with PCOS have been included in this study. Serum prolactin, total testosterone, follicular-stimulating hormone (FSH) and luteinizing hormone (LH) levels have been used as biochemical markers, before and after procedures. Laparoscopic ovarian drilling was successfully employed without any surgical complications and on an average follow-up time of 24 weeks after the procedure. During the follow-up serum values for prolactin, total testosterone and LH have decreased significantly and FSH levels remained unchanged after the procedure. The LOD in patients with PCOS may avoid or reduce the risk of OHSS and the multiple pregnancy rate induced by gonadotropin therapy. The high pregnancy rate and the economic aspect of the procedure offer an attractive management for patients with PCOS. However, LOD can be considered as second-line treatment after clomiphene citrate treatment failure and/or resistance.

Rupture of the medial head of the gastrocnemius muscle occurs when the muscle is overstretched by dorsiflexion of the ankle with the knee in full extension. Muscle ultrasound (US) is a convenient diagnostic imaging technique for visualizing normal and pathological muscle tissue as it is a non-invasive real-time examination. Muscle US can also be used in the follow-up of patients with neuromuscular disorders. The aim of this paper is to describe US monitoring of the rehabilitation process in a dog undergoing diathermy treatment (TECAR) due to rupture of the proximal medial head of the gastrocnemius muscle and to show the changes in US appearance of the muscle before, during and after rehabilitation.

Ultrasonography (US) is a safe and available real-time, high-resolution imaging method, which during the last decades has been increasingly integrated as a clinical tool in gastroenterology. New US applications have emerged with enforced data software and new technical solutions, including strain evaluation, three-dimensional imaging and use of ultrasound contrast agents. Specific gastroenterologic applications have been developed by combining US with other diagnostic or therapeutic methods, such as endoscopy, manometry, puncture needles, diathermy and stents. US provides detailed structural information about visceral organs without hazard to the patients and can play an important clinical role by reducing the need for invasive procedures. This paper presents different aspects of US in gastroenterology, with a special emphasis on the contribution from Nordic scientists in developing clinical applications.

Our objective was to compare the effectiveness of metformin plus clomiphene citrate vs. gonadotrophins, laparoscopic ovarian diathermy, aromatase inhibitors, N-acetyl-cysteine and other insulin sensitizers+clomiphene for improving fertility outcomes in women with clomiphene-resistant polycystic ovary syndrome. PubMed, SCOPUS and CENTRAL databases were searched until April 2014 with the key words: PCOS, polycystic ovary syndrome, metformin, clomiphene citrate, ovulation induction and pregnancy. The search was limited to articles conducted with humans and published in English. The PRISMA statement was followed. Twelve randomized controlled trials (n = 1411 women) were included. Ovulation and clinical pregnancy rates per woman randomized. Compared with gonadotrophins, the metformin+clomiphene combination resulted in significantly fewer ovulations (odds ratio 0.25; 95% confidence interval 0.15-0.41; p < 0.00001, 3 trials, I(2) = 85%, n = 323) and pregnancies (odds ratio 0.45; 95% confidence interval 0.27-0.75; p = 0.002, 3 trials, I(2) = 0%, n = 323). No significant differences were found when metformin+clomiphene was compared with laparoscopic ovarian diathermy (odds ratio 0.88; 95% confidence interval 0.53-1.47; p = 0.62, 1 trial, n = 282; odds ratio 0.96; 95% confidence interval 0.60-1.54; p = 0.88, 2 trials, I(2) = 0%, n = 332, for ovulation and pregnancy rates, respectively). Likewise, no differences were observed in comparison with aromatase inhibitors (odds ratio 0.88; 95% confidence interval 0.58-1.34; p = 0.55, 3 trials, I(2) = 3%, n = 409; odds ratio 0.85; 95% confidence interval 0.53-1.36; p = 0.50, 2 trials, n = 309, for ovulation and pregnancy rates, respectively). There is evidence for the superiority of gonadotrophins, but the metformin+clomiphene combination is mainly relevant for clomiphene-resistant polycystic ovary syndrome patients and, if not effective, a next step could be gonadotrophins. More attempts with metformin+clomiphene are only relevant

GENERAL OBJECTIVE: To assess the practice of blood conservation. To determine the methods of blood conservation in use, to assess the lower limit for hemoglobin for elective procedures, to determine transfusion trigger point in practice, to find out limitations in practice and ways to improve clinical practice. This was conducted in February 2009. Self-administered questionnaires were distributed among the surgeons and anesthetists in practice at the University of Nigeria Teaching Hospital, Enugu State University Teaching Hospital, Ebonyi State University Teaching Hospital and National Orthopaedic Hospital, Enugu. The data gathered was analyzed using the SPSS software. : Of participants who agreed to fill the questionnaires, more than 50% were males. The most prevalent specialty was general surgery (24.2%), followed by orthopedics (22.6%), obstetrics and gynecology (20.7%), and anesthesia (17.7%). The lowest hemoglobin limit before the patient was allowed into the theatre for elective procedures was 10 g/dl while individual transfusion trigger points ranged from hemoglobin of 6 to 10 g/dl. Majority of the doctors would avoid homologous blood transfusion in order to avoid transfusion-related diseases and reaction. Regarding knowledge of blood conservation methods and means of avoiding homologous blood, the use of diathermy was highest (12.33%), followed by preoperative blood donation (11.87%), use of hematinics (10.96%), and tourniquet 10.5%. Also, in practice, diathermy was the most frequently used (18.69%), followed by preoperative blood donation (16.16%), use of tourniquet (15.15%), while the Ovadje cell saver was least with 0.01%. Suggestions from respondents on the ways of limiting transfusion-related problems included optimization of patients (24.5%), improvement of standard of living (17.7%), and personnel training (13.3%). There is an agreement with the global trend geared toward minimizing the use of homologous blood by doctors in these hospitals. However

In a follow-up study, women sterilised by tubal diathermy were compared with a matched group of wives of vasectomised men. Semi-structured interviews were given to a random sample drawn from a representative population. The couples were young with small families and did not have a high proportion of unplanned pregnancies or terminations. They had previously used contraception, mainly the pill or sheath. Most couples were entirely satisfied with the operation. Both groups showed an increase in pre-menstrual symptoms but there was only slight evidence that menstrual loss was affected by female sterilisation. The vasectomy couples had a higher frequency of sexual intercourse, few sexual problems and tended to have more satisfactory marriages. They had had more discussion of their decision to have the operation and the implications of counselling are considered.

Virtual reality laparoscopic simulator for assessment in gynaecology.

2003-02-01

A validated virtual reality laparoscopic simulator minimally invasive surgical trainer (MIST) 2 was used to assess the psychomotor skills of 21 gynaecologists (2 consultants, 8 registrars and 11 senior house officers). Nine gynaecologists failed to complete the VR tasks at the first attempt and were excluded for sequential evaluation. Each of the remaining 12 gynaecologists were tested on MIST 2 on four occasions within four weeks. The MIST 2 simulator provided quantitative data on time to complete tasks, errors, economy of movement and economy of diathermy use--for both right and left hand performance. The results show a significant early learning curve for the majority of tasks which plateaued by the third session. This suggests a high quality surgeon-computer interface. MIST 2 provides objective assessment of laparoscopic skills in gynaecologists.

The technique of laparoscopic cholecystectomy (LC) still has areas of refinements. To decrease the number of ports, a cannula may be replaced by a percutaneous suture suspension of the gallbladder. The risk of tissue injury caused by repeat blind extraction and insertion of various instruments in and out of the abdomen may be decreased by the use of the multipurpose harmonic dissector. One hundred consecutive patients with symptomatic cholelithiasis underwent 3-port LC entirely performed by harmonic dissector without cystic duct and artery clipping. In 8 cases, a fourth trocar was necessary. In 2 cases, the cystic duct was clipped after an unsafe ultrasound sealing. In 1 case, continuous bleeding from the liver required the use of diathermy. No common bile duct injury was registered. The 3-port harmonic LC is a feasible, effective, and safe technique.

The problem of meetings and congresses of otologists and laryngologists from 1876 till 1928 is described widely. The First International Congress of Otorhinolaryngologists was performed in 1928 in Copenhagen. It was a unique meeting with numerous magnificent social entertainments with participation of several hundred physicians. The chief of editorial committee was Karl Schmigielow (1856-). The programmatic subject matters: the problems of otitis media, the problems of aural operations, the problems of postinflammatory complications of ear with intracranial complications, the problems of sinusitis, the septic complications of pharyngeal origin, the use of diathermy in treatment of tumors in E.N.T., the problems of malignant neoplasms of larynx, the problems of scleroma of upper respiratory tract, the problems of brain tumors were discussed with full particular. The labyrinthical report of Bronislaw B. Karbowski was well-disposed accepted.

Oxford Optronix MPM 3S: a clinical assessment of a microvascular perfusion monitor.

PubMed

Dryden, C M; Gray, W M; Asbury, A J

1992-01-01

The Oxford Optronix MPM 3S is a new microvascular perfusion monitor which is promoted as a device for use in the operating theatre. It uses a semiconductor laser diode and applies the Doppler principle to derive a semi-quantitative estimation of microvascular flow. We assessed this instrument with eight healthy volunteers who each performed eight different orthostatic arm manoeuvres while forearm skin blood flow was monitored. The different manoeuvres caused statistically significant changes in the instrument's reading which generally were consistent with expected changes in blood flow. The monitor also was assessed in the theatre environment with four anaesthetized patients. It proved easy to use, and was not subject to electrical interference from other equipment including short-wave diathermy. The major practical limitation of the technique is the semi-quantitative nature of the measurement. The instrument appears to have potential clinical uses in plastic and vascular surgery.

To determine the technical feasibility of a novel approach of in-situ fenestration of aortic stent grafts by using a remotely controlled robotic steerable catheter system in the porcine model. A 65-kg pig underwent robot-assisted bilateral antegrade in-situ renal fenestration of an abdominal aortic stent graft with subsequent successful deployment of a bare metal stent into the right renal artery. A 16-mm iliac extension covered stent served as the porcine aortic endograft. Under fluoroscopic guidance, the graft was punctured with a 20-G customized diathermy needle that was introduced and kept in place by the robotic arm. The needle was exchanged for a 4 x 20 mm cutting balloon before successful deployment of the renal stent. Robot-assisted antegrade in-situ fenestration is technically feasible in a large mammalian model. The robotic system enables precise manipulation, stable positioning, and minimum instrumentation of the aorta and its branches while minimizing radiation exposure.

Virtual reality as a metric for the assessment of laparoscopic psychomotor skills. Learning curves and reliability measures.

PubMed

Gallagher, A G; Satava, R M

2002-12-01

The objective assessment of the psychomotor skills of surgeons is now a priority; however, this is a difficult task because of measurement difficulties associated with the assessment of surgery in vivo. In this study, virtual reality (VR) was used to overcome these problems. Twelve experienced (>50 minimal-access procedures), 12 inexperienced laparoscopic surgeons (<10 minimal-access procedures), and 12 laparoscopic novices participated in the study. Each subject completed 10 trials on the Minimally Invasive Surgical Trainer; Virtual Reality (MIST VR). Experienced laparoscopic surgeons performed the tasks significantly (p < 0.01) faster, with less error, more economy in the movement of instruments and the use of diathermy, and with greater consistency in performance. The standardized coefficient alpha for performance measures ranged from a = 0.89 to 0.98, showing high internal measurement consistency. Test-retest reliability ranged from r = 0.96 to r = 0.5. VR is a useful tool for evaluating the psychomotor skills needed to perform laparoscopic surgery.

Randomized single-blind clinical trial of intradermal methylene blue on pain reduction after open diathermy haemorrhoidectomy.

Open haemorrhoidectomy has been associated with considerable postoperative pain and discomfort. Perianal intradermal injection of methylene blue has been shown to ablate perianal nerve endings and may bring about temporary pain relief after haemorrhoidectomy. We hypothesized that the administration of intradermal methylene blue would reduce postoperative pain during the initial period after surgery. A randomized, prospective, single-blind placebo-controlled trial was conducted. Patients were randomized to intradermal injection at haemorrhoidectomy of either 4 ml 1% methylene blue and 16 ml 0.5% marcaine or of 16 ml 0.5% marcaine and 4 ml saline prior to surgical dissection. Patients were asked to fill in a pain diary with a visual analogue scale. The primary outcome measure was pain score and analgesic use. Secondary outcomes were complications. There were 37 patients in the methylene blue arm and 30 patients in the placebo arm. There were no statistically significant differences in the sex, type of haemorrhoid, number of haemorrhoids excised, duration of surgery or hospital stay. The mean pain scores were significantly lower and the use of paracetamol was also significantly less in the methylene blue group during the first three postoperative days. The risk ratio of acute urinary retention occurring when methylene blue was not used was 2.320 (95% CI 1.754-3.067). Other complication rates were not significantly different. Perianal intradermal injection of methylene blue was useful in reducing the initial postoperative pain of open haemorrhoidectomy.

The present circuit was designed to apply to human tissue impedance tuning and matching device in ultra-short wave treatment equipment. In order to judge if the optimum status of circuit parameter between energy emitter circuit and accepter circuit is in well syntony, we designed a high frequency envelope detect circuit to coordinate with automatic adjust device of accepter circuit, which would achieve the function of human tissue impedance matching and tuning. Using the sampling coil to receive the signal of amplitude-modulated wave, we compared the voltage signal of envelope detect circuit with electric current of energy emitter circuit. The result of experimental study was that the signal, which was transformed by the envelope detect circuit, was stable and could be recognized by low speed Analog to Digital Converter (ADC) and was proportional to the electric current signal of energy emitter circuit. It could be concluded that the voltage, transformed by envelope detect circuit can mirror the real circuit state of syntony and realize the function of human tissue impedance collecting.

1996-01-01

For the development of the therapy using electricity as agent two tracks can be identified. On the one side, the indication for applying this therapy was handled more careful, simultaneously the technical equipment was improved. The Polish noble man Alexander Sapieha (1773-1812), the leading natural scientist of the Granddukedom of Warsaw, cooperated with excellent European scientists in order to improve the galvanic battery technologically. Among these scientists were Alexander Volta (1745-1827), the inventor of the battery, and Johann Bartholomaeus Trommsdorff (1770-1837), who is considered as one of the founders of scientific pharmacy in Europe. A. Sapieha supported the publication of galvanic experiences, e.g. in the case of Alexander of Humboldt (1769-1859) by publishing his paper about electric fishes. Sapiehas connections with the scientific centers in Turin and Bologna, Erfurt, Warszaw and Paris accelerated the exchange of information about galvanism. Later the resulting mini-batteries were employed in diathermie, in defibrillators and pacemakers. Details about these connections are presented in the lecture resp. full paper.

Physiotherapy interventions for patients with chronic pelvic pain: A systematic review of the literature.

To summarize the available scientific evidence on physiotherapy interventions in the management of chronic pelvic pain (CPP). A systematic review of randomized controlled trials was performed. An electronic search of MEDLINE, CINAHL, and Web of Science databases was performed to identify relevant randomized trials from 2010-2016. Manuscripts were included if at least one of the comparison groups received a physiotherapy intervention. Studies were assessed in duplicate for data extraction and risk of bias using the Physiotherapy Evidence Database scale PEDro. Eight of the studies screened met the inclusion criteria. Four manuscripts studied the effects of electrotherapy including intravaginal electrical stimulation, short wave diathermy, respiratory-gated auricular vagal afferent nerve stimulation, percutaneous tibial nerve stimulation, and sono-electro-magnetic therapy with positive results. Three studies focused on manual assessing the efficacy of myofascial versus massage therapy in two of them and ischemic compression for trigger points. Although physiotherapy interventions show some beneficial effects, evidence cannot support the results. Heterogeneity in terms of population phenotype, methodological quality, interpretation of results, and operational definition result in little overall evidence to guide treatment.

Tubeless PNL (percutaneous nephrolithotomy), in a highly selected group of patients, is a modification aimed at reducing the morbidity of PNL. We present a simple technique of achieving tract hemostasis as an adjunct to the safe performance of a tubeless PNL. Charts of 40 consecutive patients who underwent tubeless PNL at our center were reviewed. In the latter 20 consecutive patients, diathermy coagulation of the intrarenal bleeders and tract was done and these patients were compared with the earlier 20 patients in whom fulguration was not done. Drop in hemoglobin, postoperative analgesic requirement, operating time, length of hospitalization and postoperative complications were compared. No statistical difference was found between the operative times and drop in hemoglobin for both the groups. The length of hospitalization and postoperative analgesic requirement were significantly less in the fulguration group. No significant complications were noted in either of the two groups. Fulguration of visible intrarenal and tract bleeders is a simple, safe and effective hemostatic adjunct in patients undergoing tubeless PNL. copyright 2004 S. Karger AG, Basel

Hepatic pseudoaneurysm is rare and potentially fatal. It occurs as a consequence of injury to the vascular wall, erosion diathermy through clips, biliary leakage and secondary infection. The main symptom is intra-abdominal bleeding. To communicate the case of two patients with hepatic pseudoaneurysm. Case 1: We present a 43 year-old male with a history of grade IV liver injury due to blunt abdominal trauma and managed surgically. Case 2: A 67 year-old man with bile duct injury after laparoscopic cholecystectomy. Both patients presented with biliary leakage, abdominal sepsis and late intra-abdominal bleeding. Tomographic studies showed the lesion. Superselective embolization was performed proximal and distal to the lesion with good results. During follow-up, none of them showed signs of recurrent bleeding. Hepatic artery pseudoaneurysm is rare and usually secondary to bile duct injury associated with vascular injury after cholecystectomy or liver trauma. Arteriography with embolization is the best diagnostic and therapeutic procedure. Surgery is indicated for hemodynamically unstable patients, embolization failure or rebleeding. Early diagnosis reduces morbidity and mortality of this complication.

One goal of therapeutic ultrasound is enabling heat generation in tissue. Ultrasound application protocols typically neglect these processes of absorption and backscatter/reflection at the skin/fat, fat/muscle, and muscle/bone interfaces. The aim of this study was to investigate the heating process at interfaces close to the transducer and the bone with the aid of computer simulation and tissue-mimicking materials (phantoms). The experimental setup consists of physiotherapeutic ultrasound equipment for irradiation, two layers of soft tissue-mimicking material, and one with and one without an additional layer of bone-mimicking material. Thermocouple monitoring is used in both cases. A computational model is used with the experimental parameters in a COMSOL® software platform. The experimental results show significant temperature rise (42 °C) at 10 mm depth, regardless of bone layer presence, diverging 3 °C from the simulated values. The probable causes are thermocouple and transducer heating and interface reverberations. There was no statistical difference in the experimental results with and without the cortical bone for the central thermocouple of the first interface [ t (38) = -1.52; 95% CI = -0.85, 0.12; p  = 14]. Temperature rise (>6 °C) close to the bone layer was lower than predicted (>21 °C), possibly because without the bone layer, thermocouples at 30 mm make contact with the water bath and convection intensifies heat loss; this factor was omitted in the simulation model. This work suggests that more attention should be given to soft tissue layer interfaces in ultrasound therapeutic procedures even in the absence of a close bone layer.

This study aims to establish which physicians represent the suitable target group of a virtual training laboratory. Novices (48 physicians with fewer than 10 laparoscopic operations) and intermediate trainees (19 physicians who performed 30-50 laparoscopic operations) participated in this study. Each participant performed the basic module 'clip application' at the beginning and after a 1-hour short training course on the LapSim. The course consisted of the tasks coordination, lift and grasp, clip application, cutting with diathermy and fine dissection at increasing difficulty levels. The time taken to complete the tasks, number of errors, and economy of motion parameters (path length and angular path) were analyzed. Following training with the simulator, novices completed the task significantly faster (p = 0.001), demonstrated a greater economy of motion [path length (p = 0.04) and angular path (p = 0.01)]. In contrast, the intermediate trainees showed a reduction of their errors, but without reaching statistical significance. They showed no improvement in economy of motion and completed the task significantly slower (p = 0.03). Novices, in comparison to intermediate trainees, tend to benefit most during their first exposure to a laparoscopy simulator.

One-step endosonography-guided drainage of a pancreatic pseudocyst: a new technique of stent delivery through the echo endoscope.

We report here the first case of a one-step endosonography(EUS)-guided pseudocyst drainage. A prototype large channel curved array echo endoscope (Pentax FG-38 UX) and a prototype delivery system for placement of an endoprosthesis was used for the procedure. The delivery system (GIP MedicinTechnik GmbH/Medi-Globe Corporation) consists of a handle part with a piston, a metal ring sheath, a plastic catheter with a diathermy needle and a double pigtail endoprosthesis (8.5 Fr). When mounted on the endoscope the endoprosthesis can be advanced out of the distal end of the endoscope. The introduction of the stent as well as the stent release can be monitored entirely by ultrasound. The procedure was tested in a 76-year-old woman with a pseudocyst measuring 60 mm in diameter located in the tail of the pancreas. The procedure was well tolerated by the patient, and there were no procedural complications. The advantage of a large channel echo endoscope and our new prototype delivery system is that the endoprosthesis can be inserted in to a pancreatic cyst guided exclusively by EUS without exchange of endoscopes, catheters or guide wires. Further studies are warranted.

The hazards of electrocautery smoke have been known for decades. However, few clinical studies have been conducted to analyze the responsible variables of the smoke production. This study collected clinical smoke samples and systematically analyzed all possible factors. Thirty diathermy smoke samples were collected during mastectomy and abdominal cavity operations. Samples were analyzed using a gas chromatographer with a flame ionization detector. Data were applied to construct prediction models for chemical production from electrosurgeries to identify all possible factors that impact chemical production during electrosurgery. Toluene was detected in 27 smoke samples (90%) with concentrations of 0.003-0.463 mg/m(3) and production of 176.0-2,780.0 ng. Ethyl benzene and styrene were identified in very few cases. General linear regression analysis demonstrates that surgery type, patient age, electrocautery duration and imparted coagulation energy explained 67.63% of the variation in toluene production. Surgery type and patient age are known prior to surgery. In terms of risk precaution, the operating team should pay close attention to exposure when certain positive factors of increasing the chemical production are known in advance. Copyright © 2011 S.

The aim of this prospective randomized single blind study was to determine the depth of thermal damage to tonsillar tissue due to coblation, and to compare it with thermal damage to tonsillar tissue following conventional tonsillectomy; to correlate the depth of thermal damage to tonsillar tissue with the parameters of postoperative morbidity, to compare intraoperative blood loss, postoperative pain severity, time to resuming normal physical activity, and incidence of postoperative bleeding between two groups of tonsillectomized children aged up to 16 years. 72 children aged 3-16 years scheduled for tonsillectomy randomly assigned into two groups submitted either to conventional tonsillectomy with bipolar diathermy coagulation or to coblation tonsillectomy, with a 14-day follow up. Statistically significant differences were observed in the depth of thermal damage to tonsillar tissue (p < 0.001), intraoperative blood loss (p < 0.004), in postoperative pain severity (p < 0.05) and in time to resuming normal physical activity between the two groups (p < 0.001). There was no case of reactionary or secondary bleeding in either group. In this paper for the first time we have correlated postoperative morbidity and thermal tissue damage: less thermal damage is associated with less postoperative morbidity.

Consensus has not been reached regarding the optimal reduction procedure for inferior turbinate hypertrophy in allergic rhinitis and whether such procedures result in improvement in mucosal architecture. Twenty-nine patients aged 18-45 years (mean 26.8 years), with allergic rhinitis and inferior turbinate hypertrophy not responsive to medical therapy who underwent endoscopic submucosal diathermy (ESMD) (14 patients) or endoscopic submucosal resection (ESMR) (15 patients) with intraoperative and 3-6 months postoperative inferior turbinate biopsies, were included in the study. Epithelial and mucosal architecture was compared between the two groups. Both groups showed a significant decrease in epithelial denudation (p < 0.001), reversal of basement membrane thickening (p < 0.001) and increase in density of cilia (p < 0.001). The degree of improvement in histological characteristics between ESMD and ESMR groups was not significant. Surgical intervention for inferior turbinate hypertrophy by both ESMD and ESMR results in significant restoration of nasal mucosal epithelium in patients with allergic rhinitis as early as 3-month postoperatively. There was, however, no significant difference in the histological changes between those who underwent ESMD and ESMR. CTRI/2015/01/005373.

To compare the effectiveness of Doctor Tecar TherapyTM with that of laser therapy in the management of low back pain (LBP), a total of 60 patients with LBP were enrolled. The participants were randomly divided into two groups: a Tecar group (experimental group, 30 subjects), and a laser group (control group, 30 subjects). All the subjects received 10 sessions of therapy: one each day from Monday to Friday and the same again the following week. All the subjects were evaluated for pain (VAS) and disability (Roland and Morris score and Oswestry score) at baseline (T0), and 2 weeks (T1), 1 month (T2) and 2 months (T3) after the end of treatment. The pain and disability presented a trend to improvement over time in both groups. This improvement was statistically significant at all follow-ups (FUs) in the Tecar group but only at T1 for the Laser group (p less than 0.01). Comparing the two methods, there emerged a significant difference in favour of the Tecar group at T2 and T3 (p less than 0.01). The results show that Tecar therapy determined significant improvement already by the end of the treatment. Moreover, at the first and second month FUs, the Tecar therapy showed statistically better results than laser therapy.

Surgical fires, a clear and present danger.

Yardley, I E; Donaldson, L J

2010-04-01

A surgical fire is potentially devastating for a patient. Fire has been recognised as a potential complication of surgery for many years. Surgical fires continue to happen with alarming frequency. We present a review of the literature and an examination of possible solutions to this problem. The PubMed and Medline databases from 1948 onwards were searched using the subject headings "operating rooms", "fire", "safety" and "safety management". "Surgical fire" was also searched as a keyword. Relevant references from articles were obtained. Fire occurs when the three elements of the fire triad, fuel, oxidiser and ignition coincide. Surgical fires are unusual in the absence of an oxygen-enriched atmosphere. The ignition source is most commonly diathermy but lasers carry a relatively greater risk. The majority of fires occur during head and neck surgery. This is due to the presence of oxygen and the extensive use of lasers. The risk of fire can be reduced with an awareness of the risk and good communication. Surgery will always carry a risk of fire. Reducing this risk requires a concerted effort from all team members.

The da Vinci Xi robot has been introduced as the successor to the Si platform. The promise of the Xi is to open the door to new surgical procedures. For robotic-assisted radical prostatectomy (RARP)/pelvic surgery, the potential is better vision and longer instruments. How has the Xi impacted on operative and pathological parameters as indicators of surgical performance? This is a comparison of an initial series of 42 RARPs with the Xi system in 2015 with a series using the Si system immediately before Xi uptake in the same calendar year, and an Si series by the same surgeon synchronously as the Xi series using operative time, blood loss, and positive margins as surrogates of surgical performance. Subjectively and objectively, there is a learning curve to Xi uptake in longer operative times but no impact on T2 positive margins which are the most reflective single measure of RARP outcomes. Subjectively, the vision of the Xi is inferior to the Si system, and the integrated diathermy system and automated setup are quirky. All require experience to overcome. There is a learning curve to progress from the Si to Xi da Vinci surgical platforms, but this does not negatively impact the outcome.

The latest robotic bipolar vessel sealing tools have been described to be effective allowing to perform procedures with reduced blood loss and shorter operative times. The aim of this study was to assess the efficacy and reliability of these devices applied in different robotic procedures. All robotic operations, between 2014 and 2016, were performed using the EndoWrist One VesselSealer (EWO, Intuitive Surgical, Sunnyvale, CA), a bipolar fully wristed device. Data, including age, gender, body mass index (BMI), were collected. Robot docking time, intraoperative blood loss, robot malfunctioning and overall operative time were analyzed. A meta-analysis of the literature was carried out to point the attention to three different parameters (mean blood loss, operating time and hospital stay) trying to identify how different coagulation devices may affect them. In 73 robotic procedures, the mean operative time was 118.2 minutes (75-125 minutes). Mean hospital stay was four days (2-10 days). There were two post-operative complications (2.74%). The bipolar vessel sealer offers the efficacy of bipolar diathermy and the advantages of a fully wristed instrument. It does not require any change of instruments for coagulation or involvement of the bedside assistant surgeon. These characteristics lead to a reduction in operative time.

The aim of this study was to describe a new stapes prosthesis with memory characteristics for wire crimping (SMart-Piston). This technique was used in 15 patients (mean age 43.4 years; range 28-71) undergoing routine stapes surgery. SMart-Piston prostheses with a shaft diameter of 0.5 mm and length ranging from 4.25-4.5 mm were used. Heat induced wire crimping was performed by CO2 laser in five patients, and by bipolar diathermy forceps in ten patients. In 15 patients, postoperative audiological testing was performed at an average 21.9 days and in another 10 again after 435 days following surgery. The median observed air-bone-gap (ABG) postoperatively was 8.7 dB+/-7.7 dB. A total of 73% of all patients had an ABG of 10 dB or less, and all patients had less than 20 dB. In the ten patients controlled after 435 days, the ABG was 4.4 dB+/-2.4 dB. It was lower than 10 dB in all individuals. A critical point in every stapes surgery, the prosthesis fixation to the incus, is greatly facilitated by this novel technique. Long-term results in a larger group of patients are pending.

The aim of this study was to investigate the therapeutic effect of stretching combined with ultrashort wave on joint contracture and explore its possible mechanism. Thirty-two rabbits underwent unilateral immobilization of a knee joint at full extension to cause joint contracture. At 6 wks after immobilization, the rabbits were randomly divided into the following four groups: natural recovery group, stretching treatment group, ultrashort wave treatment group, and combined treatment group. For comparison, eight control group animals of corresponding age were also examined. The effect of stretching and ultrashort wave treatment on joint contracture was assessed by measuring the joint range of motion, evaluating the collagen deposition of joint capsule and assessing the mRNA and protein levels for transforming growth factor β1 in the joint capsule. The combined treatment group led to the best recovery of joint function. The combined treatment with stretching and ultrashort wave was more effective than stretching or ultrashort wave treatment alone against the synovial thickening of suprapatellar joint capsule, the collagen deposition of anterior joint capsule, and the elevated expression of transforming growth factor β1 in the joint capsule. Stretching combined with ultrashort wave treatment was effective in improving joint range of motion, reducing the biomechanical, histological, and molecular manifestations of joint capsule fibrosis in a rabbit model of extending joint contracture.

Increasing constraints on the time and resources needed to train surgeons have led to a new emphasis on finding innovative ways to teach surgical skills outside the operating room. Virtual reality training has been proposed as a method to both instruct surgical students and evaluate the psychomotor components of minimally invasive surgery ex vivo. The performance of 100 laparoscopic novices was compared to that of 12 experienced (>50 minimally invasive procedures) and 12 inexperienced (<10 minimally invasive procedures) laparoscopic surgeons. The values of the experienced surgeons' performance were used as benchmark comparators (or criterion measures). Each subject completed six tasks on the Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR) three times. The outcome measures were time to complete the task, number of errors, economy of instrument movement, and economy of diathermy. After three trials, the mean performance of the medical students approached that of the experienced surgeons. However, 7-27% of the scores of the students fell more than two SD below the mean scores of the experienced surgeons (the criterion level). The MIST-VR system is capable of evaluating the psychomotor skills necessary in laparoscopic surgery and discriminating between experts and novices. Furthermore, although some novices improved their skills quickly, a subset had difficulty acquiring the psychomotor skills. The MIST-VR may be useful in identifying that subset of novices.

Metallic materials are well known to strongly interact with electromagnetic fields. While biological effects of such field have been extensively studied, only few works dealt with the interactions of electromagnetic waves with passive metallic device implanted in biological system. Hence only several numerical and phantom simulation studies were focusing on this aspect, whereas no in situ anatomic experiment has been previously performed. In this study the effect of electromagnetic waves on eight different orthopaedic medical devices (six plates from 55 to 318mm length, a total knee and a total hip prosthesis) were explored on six human cadavers. To mimic a random environmental exposure resulting from the most common frequencies band used in domestic environment and medical applications (TV and radio broadcasting, cell phone communication, MRI, diathermy treatment), a multifrequency generator emitting in VHF, UHF, GSM and GCS frequency bands was used. The different medical devices were exposed to an electromagnetic field at 50W/m(2) and 100W/m(2). After 6min exposure, the temperature was measured on three points close to each medical device, and the induced currents were estimated. No significant temperature increase (<0.2°C) was finally detected; beside, a slight induced tension (up to 1.1V) was recorded but would appear too low to induce any biological side effect.

A 75-year-old woman suffering from symptomatic cholelithiasis was admitted to our hospital for elective laparoscopic cholecystectomy (LC). Intraoperatively, because of severe inflammation and dense adhesions in the region of the Calot triangle and bleeding arising from the porta hepatis which obscured the operating field, the method was converted to a conventional open approach. Copious hemostasis was achieved using sutures, clips and diathermy, and no bile duct or vascular injuries were recognized intraoperatively. Because of severe right upper quadrant abdominal pain and significant deterioration of the liver function tests (LFTs) on the first postoperative day, the patient underwent a Doppler ultrasound scan which showed absence of blood flow at the level of porta hepatis. Urgent relaparotomy revealed an ischemic liver on the right, a transected common bile duct at the level of its confluence, a divided and ligated right hepatic artery and thrombosed portal vein down to its confluence. Thrombectomy and reconstruction of the portal vein were performed to salvage the left hemiliver, and after restoration of blood flow to the left hemiliver, a right hemihepatectomy and a Roux-en-Y hepaticojejunostomy on the left were performed. Liver resection serves an important role in the case of parenchymal necrosis due to combined biliary, hepatic artery and portal vein injury following laparoscopic cholecystectomy and moreover, the operation can be safely performed in the acute setting.

Imaging of retinal and choroidal vascular tumours

PubMed Central

2013-01-01

The most common intraocular vascular tumours are choroidal haemangiomas, vasoproliferative tumours, and retinal haemangioblastomas. Rarer conditions include cavernous retinal angioma and arteriovenous malformations. Options for ablating the tumour include photodynamic therapy, argon laser photocoagulation, trans-scleral diathermy, cryotherapy, anti-angiogenic agents, plaque radiotherapy, and proton beam radiotherapy. Secondary effects are common and include retinal exudates, macular oedema, epiretinal membranes, retinal fibrosis, as well as serous and tractional retinal detachment, which are treated using standard methods (ie, intravitreal anti-angiogenic agents or steroids as well as vitreoretinal procedures, such as epiretinal membrane peeling and release of retinal traction). The detection, diagnosis, and monitoring of vascular tumours and their complications have improved considerably thanks to advances in imaging. These include spectral domain and enhanced depth imaging optical coherence tomography (SD-OCT and EDI-OCT, respectively), wide-angle photography and angiography as well as wide-angle fundus autofluorescence. Such novel imaging has provided new diagnostic clues and has profoundly influenced therapeutic strategies so that vascular tumours and secondary effects are now treated concurrently instead of sequentially, enhancing any opportunities for conserving vision and the eye. In this review, we describe how SD-OCT, EDI-OCT, autofluorescence, wide-angle photography and wide-angle angiography have facilitated the evaluation of eyes with the more common vascular tumours, that is, choroidal haemangioma, retinal vasoproliferative tumours, and retinal haemangioblastoma.

An iatrogenic caecal perforation is rare, but a serious complication associated with significant morbidity and mortality. We present a 4min and 50s video on a new improvisation undertaken during laparoscopic management of post-polypectomy caecal perforation. Our patient presented with an acute abdomen following endoscopic polypectomy. At surgery, the site of caecal perforation was close to the appendicular base with devitalization tissue, secondary to diathermy usage. The hallmark of safety within this novel technique included fresh healthy tissue margins within the endoloop (detachable snare ligation) and ensuring no ischemic tissue was gathered. Complete freeing of the appendix and meso-appendicular base was required and securing three endoloops proximal to the site of perforation. The post-operative course was uneventful. The World Society of Emergency Surgery (WSES) 2013 guidelines suggested an early laparoscopic approach is a safe and effective treatment for colonoscopy-related colonic perforation. There are no national guidelines and the management is dictated by the clinical condition of the patient, co-morbidity, size and site of perforation as well as the scale of bowel preparation, and surgical experience. The endoloop technique described, undertaken during a laparoscopy is a novel approach. It is a simple and effective method, reminding clinicians to adapt techniques when necessary. Nevertheless, it is only limited to perforations around the appendicular base. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

An Assessment of Hazards Caused by Electromagnetic Interaction on Humans Present near Short-Wave Physiotherapeutic Devices of Various Types Including Hazards for Users of Electronic Active Implantable Medical Devices (AIMD)

Gryz, Krzysztof

2013-01-01

Leakage of electromagnetic fields (EMF) from short-wave radiofrequency physiotherapeutic diathermies (SWDs) may cause health and safety hazards affecting unintentionally exposed workers (W) or general public (GP) members (assisting patient exposed during treatment or presenting there for other reasons). Increasing use of electronic active implantable medical devices (AIMDs), by patients, attendants, and workers, needs attention because dysfunctions of these devices may be caused by electromagnetic interactions. EMF emitted by 12 SWDs (with capacitive or inductive applicators) were assessed following international guidelines on protection against EMF exposure (International Commission on Nonionizing Radiation Protection for GP and W, new European directive 2013/35/EU for W, European Recommendation for GP, and European Standard EN 50527-1 for AIMD users). Direct EMF hazards for humans near inductive applicators were identified at a distance not exceeding 45 cm for W or 62 cm for GP, but for AIMD users up to 90 cm (twice longer than that for W and 50% longer than that for GP because EMF is pulsed modulated). Near capacitive applicators emitting continuous wave, the corresponding distances were: 120 cm for W or 150 cm for both—GP or AIMD users. This assessment does not cover patients who undergo SWD treatment (but it is usually recommended for AIMD users to be careful with EMF treatment). PMID:24089662

A Multicentre Audit of Single-Use Surgical Instruments (SUSI) for Tonsillectomy and Adenoidectomy

2007-01-01

INTRODUCTION Prions are resistant to conventional sterilisation procedures and, therefore, could be transmitted iatrogenically through re-usable adenoid and tonsil surgical instruments. Using disposable instruments would avoid the risk of transmission. We present the results of a complete audit loop using BBraun single-use surgical instruments (SUSI). PATIENTS AND METHODS This was a prospective multicentre audit. Surgeons were asked to fill in a standardised questionnaire recording details including postoperative complications, and evaluation of each piece of equipment compared with their own experience of conventional re-usable instruments. In the first cycle, constructive criticisms of the instruments were noted and the manufacturers modified the instruments accordingly. A second cycle of audit was subsequently undertaken. RESULTS A total of 86 patients were audited in the first cycle and 97 in the second cycle. Postoperative haemorrhage rate for both cycles was well within acceptable range. In the first audit cycle, surgeons generally found the Draffin rods, Boyle-Davis gag and bipolar diathermy forceps of poor quality and difficult to use. These were redesigned and, on repeat evaluation during the second audit cycle, were found to be just as good, if not better, than the re-usable instruments. CONCLUSIONS This study suggests that SUSI may be just as good as re-usable instruments. Furthermore, they may be more cost effective. PMID:18201478

Hemorrhoids and varicose veins: a review of treatment options.

PubMed

MacKay, D

2001-04-01

Hemorrhoids and varicose veins are common conditions seen by general practitioners. Both conditions have several treatment modalities for the physician to choose from. Varicose veins are treated with mechanical compression stockings. There are several over-the-counter topical agents available for hemorrhoids. Conservative therapies for both conditions include diet, lifestyle changes, and hydrotherapy which require a high degree of patient compliance to be effective. When conservative hemorrhoid therapy is ineffective, many physicians may choose other non-surgical modalities: injection sclerotherapy, cryotherapy, manual dilation of the anus, infrared photocoagulation, bipolar diathermy, direct current electrocoagulation, or rubber band ligation. Injection sclerotherapy is the non-surgical treatment for primary varicose veins. Non-surgical modalities require physicians to be specially trained, own specialized equipment, and assume associated risks. If a non-surgical approach fails, the patient is often referred to a surgeon. The costly and uncomfortable nature of treatment options often lead a patient to postpone evaluation until aggressive intervention is necessary. Oral dietary supplementation is an attractive addition to the traditional treatment of hemorrhoids and varicose veins. The loss of vascular integrity is associated with the pathogenesis of both hemorrhoids and varicose veins. Several botanical extracts have been shown to improve microcirculation, capillary flow, and vascular tone, and to strengthen the connective tissue of the perivascular amorphous substrate. Oral supplementation with Aesculus hippocastanum, Ruscus aculeatus, Centella asiatica, Hamamelis virginiana, and bioflavonoids may prevent time-consuming, painful, and expensive complications of varicose veins and hemorrhoids.

Development of Endoscopic Diagnosis and Treatment for Chronic Unilateral Hematuria: 35 Years Experience.

Tanimoto, Ryuta; Kumon, Hiromi; Bagley, Demetrius H

2017-04-01

Chronic unilateral hematuria (CUH) is also called lateralizing essential hematuria, benign essential hematuria, and benign lateralizing hematuria, which was defined as intermittent or continuous gross hematuria that cannot be diagnosed with standard radiology and hematology studies, together with unilateral bloody efflux by cystoscopy. CUH is rare, but sometimes confused with malignancy or life-threatening hemorrhage. Therefore, it can cause considerable anxiety to not only patients but also urologists. For this study, we summarized articles about endoscopic diagnosis and treatment of CUH, and discussed the development of endourology for CUH. We searched articles related to CUH that were indexed in the PubMed database and published in English. Key terms used were "unilateral," "lateralizing," "chronic," "benign," and "idiopathic" hematuria. We found 15 pertinent articles reporting CUH. Endoscopically, CUH can be classified into three categories: discrete lesion, diffuse lesion, or no (unidentified) lesion. Currently, endoscopic techniques for CUH are similar to the techniques for upper tract urothelial carcinoma, using semi-rigid and flexible ureteroscopes with diathermy fulguration or laser ablation for treatment. The overall success rate of endoscopic treatment for CUH, defined as resolution of gross hematuria after treatment, was 93% (190/205). The recurrence rate, defined as recurrent gross hematuria after treatment, was 10% (19/189). Advancements in endoscopic devices and techniques have enabled more accurate and less invasive diagnosis and treatment of CUH. Once CUH is defined, flexible ureteroscopy is the diagnostic and therapeutic technique of choice.

Auditory evoked potentials.

PubMed

De Cosmo, G; Aceto, P; Clemente, A; Congedo, E

2004-05-01

Auditory evoked potentials (AEPs) are an electrical manifestation of the brain response to an auditory stimulus. Mid-latency auditory evoked potentials (MLAEPs) and the coherent frequency of the AEP are the most promising for monitoring depth of anaesthesia. MLAEPs show graded changes with increasing anaesthetic concentration over the clinical concentration range. The latencies of Pa and Nb lengthen and their amplitudes reduce. These changes in features of waveform are similar with both inhaled and intravenous anaesthetics. Changes in latency of Pa and Nb waves are highly correlated to a transition from awake to loss of consciousness. MLAEPs recording may also provide information about cerebral processing of the auditory input, probably because it reflects activity in the temporal lobe/primary cortex, sites involved in sounds elaboration and in a complex mechanism of implicit (non declarative) memory processing. The coherent frequency has found to be disrupted by the anaesthetics as well as to be implicated in attentional mechanism. These results support the concept that the AEPs reflects the balance between the arousal effects of surgical stimulation and the depressant effects of anaesthetics. However, AEPs aren't a perfect measure of anaesthesia depth. They can't predict patients movements during surgery and the signal may be affected by muscle artefacts, diathermy and other electrical operating theatre interferences. In conclusion, once reliability of the AEPs recording became proved and the signal acquisition improved it is likely to became a routine feature of clinical anaesthetic practice.

Novel strategies in the management of polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a common endocrinopathy affecting reproductive-aged women. PCOS has been recognized as a syndrome combining reproductive and metabolic abnormalities with lifelong health implications. Cardiometabolic alterations require regular screening and effective and targeted lifestyle advice to lose weight as well as to prevent weight gain. Pharmacological therapy includes insulin-sensitizer drugs and agents that act directly on metabolic comorbidities, such as statins and antiobesity drugs. Bariatric surgery may be an option for severely obese women with PCOS Regarding reproductive aspects, ovulation induction with antiestrogens such as clomiphene citrate or letrozole is the first-line medical treatment. Exogenous gonadotropins and in vitro fertilization (IVF) are recommended as second-line treatment for anovulatory infertility. Laparoscopic ovarian diathermy may be used in special cases and metformin is no longer recommended for ovulation induction. Combined oral contraceptives (OCs) are the first-line treatment for the management of menstrual irregularities in women not seeking pregnancy, also providing endometrial protection and contraception. Progestin-only pills or cyclical progestins are recommended for those with contraindications to OCs. Metformin is also considered a second-line choice for improving menstrual cycles in women presenting insulin-resistance and dysglicemia. Hirsutism requires cosmetic procedures and medical treatment with OCs. More severe cases may need anti-androgen drugs added to the OCs. In conclusion, strategies regarding the management of reproductive issues in PCOS encompass a tailored approach to individual needs of each patient.

A novel modeling and simulation technique of photo--thermal interactions between lasers and living biological tissues undergoing multiple changes in phase.

PubMed

Dua, Rajan; Chakraborty, Suman

2005-06-01

Knowledge of heat transfer in biological bodies has many therapeutic applications involving either raising or lowering of temperature, and often requires precise monitoring of the spatial distribution of thermal histories that are produced during a treatment protocol. Extremes of temperature into the freezing and burning ranges are useful in surgical procedures for selective killing and/or removal of target tissues. For example, the primary objective of hyperthermia is to raise the temperature of the diseased tissue to a therapeutic value, typically 41- 44 degrees C, and then thermally destroy it. The present paper therefore aims to develop a mathematical model for effective simulation of photo--thermal interactions between laser rays and biological tissues. In particular, damage of biological tissues when subjected to single point laser diathermy is numerically investigated using a unique enthalpy-based approach for modeling multiple phase change, (namely, melting of fat and vaporization of water content of the tissues) and the associated release/absorption of latent heat in conjunction with unsteady state heat conduction mechanisms. The governing equations of bio-heat transfer coupled with initial and boundary conditions are solved using a finite volume approach in conjunction with line by a line tri-diagonal matrix algorithm (TDMA) solver. Temperature responses of tissues subject to laser heating are quantitatively investigated in detail using the present model, and the resultant solutions are expected to be immensely useful in a variety of Bio-thermal practices in medicine and surgery.

The posterior retroperitoneoscopic adrenalec tomy has several advantages compared with the transperitoneal approach such as a shorter and more direct route to the target organ, no breach of the intraperitoneal space, and no required retraction of the adjacent organs. It also is a safe procedure with a short learning curve.1 - 5 This report presents a challenging case of an extra-adrenal paraganglioma located in the aorto-caval space and managed using the retroperitoneal approach. A 39-year-old man was placed in the prone jackknife position, and three incisions were made in the right posterior abdominal wall for placement of the laparoscopic ports. The retroperitoneal space was entered with diathermy and blunt finger dissection, and retropneumoperitoneum was achieved with carbon dioxide insufflation pressure up to 18 mmHg. After identification of the right kidney and vessels, the tumor was meticulously dissected and excised with an energy device. The specimen was removed using a laparoscopic specimen retrieval bag, and the port sites were closed in layers. The operative time was 130 min, and the total blood loss was 30 ml. The tumor was diagnosed as a moderately differentiated extra-adrenal paraganglioma. The Von Hippel-Lindau gene mutation was detected using next-generation sequencing. The posterior retroperitoneoscopic approach is a safe, feasible, and effective method for excising an extra-adrenal paraganglioma even in the aorto-caval space. The authors suggest that this procedure is a useful surgical option for treatment of an aorto-caval paraganglioma for selected patients and by experienced surgeons.

Nikola Tesla (1856- 1943) was a genius inventor and scientist, whose contribution to medicine is remarkable. Part I of this article reviewed special contributions of the world renowned scientist to the establishment of radiology as a new discipline in medicine. This paper deals with the use of Tesla currents in medicine. Tesla Currents in Medicine. Tesla's greatest impact on medicine is his invention of a transformer (Tesla coil) for producing high frequency and high voltage currents (Tesla currents). Tesla currents are used in diathermy, as they, while passing through the body, transform electrical energy into a therapeutic heat. In 1891, Tesla passed currents through his own body and was the first to experience their beneficial effects. He kept correspondence on electrotherapy with J. Dugan and S. H. Monell. In 1896, he used high frequency currents and designed an ozone generator for producing ozone, with powerful antiseptic and antibacterial properties. Tesla is famous for his extensive experiments with mechanical vibrations and resonance, examining their effects on the organ ism and pioneering their use for medical purposes. Tesla also designed an oscillator to relieve fatigue of the leg muscles. It is less known that Tesla's inventions (Tesla coil and wireless remote control) are widely used in modern medical equipment. Apart from this, wireless technology is nowadays widely applied in numerous diagnostic and therapeutic procedures. Nikola Tesla was the last Renais- sance figure of the modern era. Tesla bridged three centuries and two millennia by his inventions, and permanently indebted humankind by his epochal discoveries.

Do soft skills predict surgical performance?: a single-center randomized controlled trial evaluating predictors of skill acquisition in virtual reality laparoscopy.

Virtual reality (VR) training in minimal invasive surgery (MIS) is feasible in surgical residency and beneficial for the performance of MIS by surgical trainees. Research on stress-coping of surgical trainees indicates the additional impact of soft skills on VR performance in the surgical curriculum. The aim of this study was to evaluate the impact of structured VR training and soft skills on VR performance of trainees. The study was designed as a single-center randomized controlled trial. Fifty first-year surgical residents with limited experience in MIS ("camera navigation" in laparoscopic cholecystectomy only) were randomized for either 3 months of VR training or no training. Basic VR performance and defined soft skills (self-efficacy, stress-coping, and motivation) were assessed prior to randomization using basic modules of the VR simulator LapSim(®) and standardized psychological questionnaires. Three months after randomization VR performance was reassessed. Outcome measurement was based on the results derived from the most complex of the basic VR modules ("diathermy cutting") as the primary end point. A correlation analysis of the VR end-point performance and the psychological scores was done in both groups. Structured VR training enhanced VR performance of surgical trainees. An additional correlation to high motivational states (P < 0.05) was found. Low levels of self-efficacy and negative stress-coping were related to poor VR performance in the untrained control group (P < 0.05). This correlation was absent in the trained intervention group (P > 0.05). Low self-efficacy and negative stress-coping strategies seem to predict poor VR performance. However, structured training along with high motivational states is likely to balance out this impairment.

In an interview with Family Planning World, Helen Axby of the Marie Stopes Clinics explains that the organization's growth at a time when the number of abortions in Great Britain has begun to decline is due to successful management and marketing. Although the British government provides from abortion services, the Marie Stopes Clinics performs over 25,000 abortions a year. According to Axby, the main reason for this is that government restrictions have created a cumbersome process where women often wait 3-4 weeks to receive an abortion. At the Stopes clinics, women receive prompt treatment in a comfortable setting. A consultation is scheduled within a day or two following the initial phone call, and the operation is scheduled at the woman's convenience. Axby explains that the organization conducts extensive advertisement in the Yellow Pages, local newspapers, and women's magazines. Though the clinic operates for profit, its services are far less expensive than what it would cost to obtain them at other private offices. In 1990, the organization grossed about 6.2 million pounds (profits were around 1 million pounds). The profits are used to fund overseas projects. Because of the decline in the number of abortions in Britain, Axby expects the organization to earn less this year. However, Marie Stopes clinics plans to fight to increase its market share of family planning services. Its fastest growing service is vasectomy. Relying on the noninvasive bipolar diathermy technique, the Stopes Clinics have made vasectomy a more simple and comfortable experience for men. Other services include employee screening (for pap smears, breast checks, etc.). Finally, Axby says that the organization might also increase its market share by acquiring its competitors.

Do we need to establish guidelines for patients with neuromodulation implantable devices, including spinal cord stimulators undergoing nonspinal surgeries?

PubMed Central

Background: Spinal cord stimulation is currently approved to treat chronic intractable pain of the trunk and limbs. However, such implantable electronic devices are vulnerable to external electrical currents and magnetic fields. Within the hospitals and modern operating rooms (ORs), there is an abundance of electrical devices and other types of equipment that could interfere with such devices. Despite the increasing number of patients with neuromodulation implantable devices, there are no written guidelines available or consensus of cautions for such patients undergoing unrelated surgery. Case Descriptions: A 60-year-old female with a permanent St. Jude's spinal cord stimulator (SCS) presented for open total abdominal hysterectomy. Both the anesthesia and gynecology staffs were aware of the device presence, but were unaware of any precautions regarding intraoperative management. The device was found to be nonmagnetic resonance imaging compatible, and bipolar cautery was used instead of monopolar cautery. A 59-year-old female with a 9-year-old permanent Medtronic SCS, presented for right total hip arthroplasty. The device was switched off prior to entering the OR, bipolar cautery was used, and grounding pads were placed away from her battery site. In each case, the manufacturer's representative was contacted preoperative. Both surgeries proceeded uneventfully. Conclusions: The Food and Drug Administration safety information manual warns about the use of diathermy, concomitant implanted stimulation devices, lithotripsy, external defibrillation, radiation therapy, ultrasonic scanning, and high-output ultrasound, all of which can lead to permanent implant damage if not turned off prior to undertaking procedures. Lack of uniform guidelines makes intraoperative management, as well as remote anesthesia care of patients with previously implanted SCSs unsafe. PMID:26958424

Minimizing blood loss at cesarean-hysterectomy for placenta previa percreta.

PubMed

Belfort, Michael A; Shamshiraz, Alireza A; Fox, Karin

2017-01-01

Preventing blood loss at the time of a cesarean delivery during a scheduled, nonemergent cesarean hysterectomy for placenta percreta may reduce the need for crystalloid and blood product transfusion. Commonly a classical hysterotomy is created and this can result in as much as a 500-800 mL blood loss before the hysterotomy is closed. Our technique involves placement of 4 full-thickness interrupted sutures in a box pattern to create an unperfused area of upper uterine segment. Diathermy is used to open the uterus to the membranes in the center of the "box" without blood loss. A finger is then inserted between the membranes and uterus to create a space into which 1 side of an 80-mm linear cutting stapler is introduced. The other side of the stapler is then attached and clamped closed, and the stapler is activated. Forward motion of the lever lays down 2 rows of staples, and backward movement of the lever divides the uterine muscle between the 2 staple lines. The stapler is removed and reloaded and reintroduced 1 or 2 times as needed to create an avascular hysterotomy large enough to atraumatically deliver the baby. The membranes are then opened and the baby is delivered. Following this the umbilical cord is clamped and cut without any attempt to remove the placenta, replaced in the uterine cavity, and the hysterotomy is closed with a running locked suture that incorporates the membrane edges. The hysterectomy then proceeds. In most cases there is minimal blood loss (usually <20 mL) from the cesarean delivery. Copyright © 2016 Elsevier Inc. All rights reserved.

The use of LigaSure™ vessel sealing system in head and neck surgery was reported to be reliable and safe, providing sufficient hemostasis and reducing operating time. The aim of this study was to evaluate efficacy of this technique in patients undergoing selective neck dissections. This study was carried out as a prospective controlled study at an otolaryngology department of a tertiary medical center between July 2013 and July 2015. Twenty-five patients older than 18 years who underwent unilateral selective neck dissection for head and neck cancer were included in the study. In the control group (group 2, 10 patients) only monopolar and bipolar diathermy was used; in the Ligasure group (group 1, 15 patients) Ligasure was used for hemostasis and dissection in addition to the conventional techniques. Cervical lymphadenectomy time, operation time, preoperative hemoglobin levels, preoperative hematocrit levels, postoperative hemoglobin levels, postoperative hematocrit levels, total neck drainage and drain removal time were analyzed and compared between the groups. Median operation time in group 1 and 2 were 95 min (IQR = 35) and 142.5 min (IQR = 63), respectively. Median cervical lymphadenectomy time in group 1 and 2 were 55 min (IQR = 23) and 102.5 min (IQR = 49), respectively. Median operation time and cervical operation time were significantly lower in group 1 (p < 0.05). In conclusion, LigaSure™ vessel sealing system is a safe, efficacious technique and significantly lowers cervical lymphadenectomy and operation time in selective neck dissections compared to controls. Given the superb hemostatic properties, this technique should be in the surgeon's armamentarium when possible.

Single incision laparoscopic surgery (SILS) represents the latest advancement in minimally invasive surgery, combining the benefits of conventional laparoscopic surgery, such as less pain and faster recovery, with improved cosmesis. Although the successful use of this technique is well reported in general surgery and urology, there is a lack of studies on SILS in gynaecology. To evaluate the feasibility, safety, cosmesis and outcome of SILS in gynaecology. A prospective case series analysis of 105 women scheduled to undergo surgery by SILS from August 2010 to November 2011. Intra-operative data such as operative time, estimated blood loss, complications, additional ports and hospital stay were collected. Post-operative pain and cosmetic outcomes (scar size) were also recorded. Out of 105 women, SILS was performed for 84 (60 excisions of endometriosis, 13 divisions of adhesions, five hysterectomies, two mesh sacrohysteropexies and four ovarian cystectomies). SILS was not undertaken for 21 women because of a number of factors, including the lack of required equipment (eg bariatric scope, SILS port, roticulating instruments and diathermy leads). Four women required insertion of additional ports because of surgical difficulties. One intra-operative (uterine perforation) and seven post-operative complications (six wound infections and one vault haematoma) occurred. Mean operation times were as follows: mesh sacrohysteropexy - 60 min, excision of endometriosis - 55 min, hysterectomy - 150 min, laparoscopic division of adhesions - 62 min and ovarian cystectomy - 40 min. Our experience shows that SILS is a feasible and safe technique for the surgical management of various gynaecological conditions. Satisfaction is high because of improved cosmesis and reduced analgesic requirements post-operatively. © 2012 The Authors ANZJOG © 2012 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

The aim of this retrospective study was to assess our experience of 41 patients with anal fistulae treated with video-assisted anal fistula treatment (VAAFT). Forty-one consecutive patients with cryptoglandular anal fistulae were included. Patients with low intersphincteric anal fistulae or those with gross perineal abscess were excluded. Eleven (27 %) patients had undergone prior fistula surgery with 5 (12 %) having had three or more previous operations. All patients underwent the diagnostic phase as well as diathermy and curettage of the fistula tracts during VAAFT. Primary healing rate was 70.7 % at a median follow-up of 34 months. Twelve patients recurred or did not heal and underwent a repeat VAAFT procedure utilising various methods of dealing with the internal opening. There was a secondary healing rate of 83 % with two recurrences. Overall, stapling of the internal opening had a 22 % recurrence rate, while anorectal advancement flap had a 75 % failure rate. There was no recurrence seen in six cases after using the over-the-scope-clip (OTSC(®)) system to secure the internal opening. VAAFT is useful in the identification of fistula tracts and enables closure of the internal opening. Adequate closure is essential with the method used to close large or fibrotic internal openings being the determining factor for success or failure. The OTSC system delivered the most consistent result without leaving a substantial perianal wound. Ensuring thorough curettage and drainage of the tract during VAAFT is also important to facilitate healing. We believe that this understanding will bring about a decrease in the high recurrence rates currently seen in many series of anal fistulae.

The key bimanual instrument tasks involved in laparoscopic surgery have been abstracted for use in a virtual reality surgical skills evaluator and trainer. The trainer uses two laparoscopic instruments mounted on a frame with position sensors which provide instrument movement data that is translated into interactive real time graphics on a PC (P133, 16 Mb RAM, graphics acceleration card). An accurately scaled operating volume of 10 cm3 is represented by a 3D cube on the computer screen. "Camera" position and size of target objects can be varied for different skill levels. Targets appear randomly within the operating volume according to the skill task and can be grasped and manipulated with the instruments. Accuracy and errors during the tasks and time to completion are logged. Mist VR has tutorial, training, examination, analysis and configuration modes. Six tasks have been selected and include combinations of instrument approach, target acquisition, target manipulation and placement, transfer between instruments, target contact with optional diathermy, and controlled instrument withdrawal/replacement. Tasks can be configured for varying degrees of difficulty and the configurations saved to a library for reuse. Specific task configurations can be assigned to individual students. In the examination mode the supervisor can select the tasks, repetitions and order and save to a specific file for that trainee. Progress can be assessed and there is the option for playback of the training session or examination. Data analyses permit overall, including task, and right or left hand performances to be quantified. Mist VR represents a significant advance over the subjective assessment of training performances with existing "plastic box" basic trainers.

The role of obesity in the development of polycystic ovary syndrome.

Motta, Alicia Beatriz

Polycystic Ovary Syndrome (PCOS) is one of the common endocrine diseases that affects women in their reproductive age. PCOS has diverse clinical implications that include reproductive (infertility, hyperandrogenism, hirsutism), metabolic (insulin resistance, impaired glucose tolerance, type 2 diabetes mellitus, cardiovascular diseases) and psychological features (increased anxiety, depression and worsened quality of life). The exact patho-physiology of PCOS is complex and remains largely unclear. The prevalence of PCOS is estimated at 4-18%, depending on diverse factors discussed ahead. The phenotype varies widely depending on life stage, genotype, ethnicity and environmental factors including lifestyle and body weight. During the last decades, obesity and excess weight are major chronic diseases all around the word. Obesity increases some features of PCOS such as hyperandrogenism, hirsutism, infertility and pregnancy complications. Both obesity and insulin resistance increase diabetes mellitus type 2 and cardiovascular diseases. Moreover, obesity impairs insulin resistance and exacerbates reproductive and metabolic features of PCOS. It is well known that obesity is associated with anovulation, pregnancy loss and late pregnancy complications (pre-eclampsia, gestational diabetes). Obesity in PCOS is also linked to failure or delayed response to the various treatments including clomiphene citrate, gonadotropins and laparoscopic ovarian diathermy. It has been reported that, after losing as little as 5 % of initial body weight obese women with PCOS improved spontaneous ovulation rates and spontaneous pregnancy. Therefore, the weight loss prior to conception improves live birth rate in obese women with or without PCOS. The treatment of obesity may include lifestyle therapy (diet and exercise), pharmacological treatment and bariatric surgery. In summary, weight loss is considered the first-line therapy in obese women with PCOS. In the present review, the consequence and

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.

The aims of this study were to produce a population-based estimate of the prevalence of work-related exposure to polycyclic aromatic hydrocarbons (PAHs), to identify the main circumstances of exposure and to describe the use of workplace control measures designed to decrease those exposures. The analysis used data from the Australian Workplace Exposures Study, a nationwide telephone survey which investigated the current prevalence and exposure circumstances of work-related exposure to 38 known or suspected carcinogens, including PAHs, among Australian workers aged 18-65 years. Using the web-based tool OccIDEAS, semi-quantitative information was collected about exposures in the current job held by the respondent. Questions were addressed primarily at tasks undertaken rather than about self-reported exposures. Of the 4,993 included respondents, 297 (5.9%) were identified as probably being exposed to PAHs in their current job [extrapolated to 6.7% of the Australian working population-677 000 (95% confidence interval 605 000-757 000) workers]. Most (81%) were male; about one-third were farmers and about one-quarter worked in technical and trades occupations. In the agriculture industry about half the workers were probably exposed to PAHs. The main exposure circumstances were exposure to smoke through burning, fighting fires or through maintaining mowers or other equipment; cleaning up ash after a fire; health workers exposed to diathermy smoke; cooking; and welding surfaces with a coating. Where information on control measures was available, their use was inconsistent. Workers are exposed to PAHs in many different occupational circumstances. Information on the exposure circumstances can be used to support decisions on appropriate priorities for intervention and control of occupational exposure to PAHs, and estimates of burden of cancer arising from occupational exposure to PAHs. © The Author 2015.

Kuzma, Scott A; Doberstein, Scott T; Rushlow, David R

To present the unique case of a collegiate wrestler with C7 neurologic symptoms due to T1-T2 disc herniation. A 23-year-old male collegiate wrestler injured his neck in a wrestling tournament match and experienced pain, weakness, and numbness in his left upper extremity. He completed that match and 1 additional match that day with mild symptoms. Evaluation by a certified athletic trainer 6 days postinjury showed radiculopathy in the C7 distribution of his left upper extremity. He was evaluated further by the team physician, a primary care physician, and a neurosurgeon. Cervical spine injury, stinger/burner, peripheral nerve injury, spinal cord injury, thoracic outlet syndrome, brachial plexus radiculopathy. The patient initially underwent nonoperative management with ice, heat, massage, electrical stimulation, shortwave diathermy, and nonsteroidal anti-inflammatory drugs without symptom resolution. Cervical spine radiographs were negative for bony pathologic conditions. Magnetic resonance imaging showed evidence of T1-T2 disc herniation. The patient underwent surgery to resolve the symptoms and enable him to participate for the remainder of the wrestling season. Whereas brachial plexus radiculopathy commonly is seen in collision sports, a postfixed brachial plexus in which the T2 nerve root has substantial contribution to the innervation of the upper extremity is a rare anatomic variation with which many health care providers are unfamiliar. The injury sustained by the wrestler appeared to be C7 radiculopathy due to a brachial plexus traction injury. However, it ultimately was diagnosed as radiculopathy due to a T1-T2 thoracic intervertebral disc herniation causing impingement of a postfixed brachial plexus and required surgical intervention. Athletic trainers and physicians need to be aware of the anatomic variations of the brachial plexus when evaluating and caring for patients with suspected brachial plexus radiculopathies.

Carbon dioxide is the standard insufflation gas for laparoscopy. However, in many areas of the world, bottled carbon dioxide is not available. Laparoscopy offers advantages over open surgery and has been practiced using filtered room air insufflation since 2006 at Bongolo Hospital in Gabon, Africa. Our primary goal was to evaluate the safety of room air insufflation related to intraoperative and postoperative complications. Our secondary aim was to review the types of cases performed laparoscopically at our institution. This retrospective review evaluates laparoscopic cases performed at Bongolo Hospital between January 2006 and December 2013. Demographic and perioperative information for patients undergoing laparoscopic procedures was collected. Insufflation was achieved using a standard, oil-free air compressor using filtered air and a standard insufflation regulator. A total of 368 laparoscopic procedures were identified within the time period. The majority of cases were gynecologic (43%). There was a 2% (8/368) complication rate with one perioperative death. The 2 complications related to insufflation were episodes of hypotension responsive to standard corrective measures. No intracorporeal combustion events were observed in any cases in which the use of diathermy and room air insufflation were combined. The other complications and the death were unrelated to the use of insufflation with air. Insufflation complications with room air occurred in our study. However, the complications related to insufflation with room air in our study were no different than those described in the literature using carbon dioxide. As room air is less costly than carbon dioxide and readily available, confirming the safety of room air insufflation in prospective studies is warranted. Room air appears to be safe for establishing and maintaining pneumoperitoneum, making laparoscopic surgery more accessible to patients in low-resource settings.

Some occupations are more prone to low back pain (LBP) due to their static work postures and work place design. Multidisciplinary pain programs have shown their effectiveness in the management of LBP in general population but which treatment and which segment of the population will be benefited more was not investigated yet. This study determines the effect of two treatment protocols on five occupationally subgrouped male LBP patients. A total of 102 occupational male, 20-40 yrs of age, with sub-acute or chronic nonspecific LBP were randomized and treated either with conventional treatment a combination of two electrotherapy (ultrasound and short wave diathermy) and one exercise therapy (lumbar strengthening exercises) or dynamic muscular stabilization techniques (DMST) an active approach of stabilizing training. At the end of the treatment, subjects of both the groups were further stratified in five subgroups on the basis of their occupation. The pain was the primary outcome measure while physical strength [back pressure changes (BPC) and abdominal pressure changes (APC)] the secondary. The Pain, BPC and APC of all subgroups improved significantly (P < 0.01) in the both treatments but more in DMST. For each variable, improvement in subgroups differed within and between the treatments. Overall improvement in all assessed variables were evident on Desk workers followed by Shop keepers the most while BPC of Movement job, APC of Others and Pain of Sedentary and Shop keepers improved the least. Study concluded that for the management of occupational LBP, DMST is more effective than conventional treatment. The Pain of Sedentary and Shopkeepers and physical strength of Movement job and Others may need more clinical attention. Findings of this study may be helpful in the management of occupational LBP.

Post-esophageal atresia anastomotic strictures and post-corrosive esophagitis are the most frequent types of cicatricial esophageal stricture. Congenital esophageal stenosis has been reported to be a rare but typical disease in children; other pediatric conditions are peptic, eosinophilic esophagitis and dystrophic recessive epidermolysis bullosa strictures. The conservative treatment of esophageal stenosis and strictures (ES) rather than surgery is a well-known strategy for children. Before planning esophageal dilation, the esophageal morphology should be assessed in detail for its length, aspect, number and level, and different conservative strategies should be chosen accordingly. Endoscopic dilators and techniques that involve different adjuvant treatment strategies have been reported and depend on the stricture's etiology, the availability of different tools and the operator's experience and preferences. Balloon and semirigid dilators are the most frequently used tools. No high-quality studies have reported on the differences in the efficacies and rates of complications associated with these two types of dilators. There is no consensus in the literature regarding the frequency of dilations or the diameter that should be achieved. The use of adjuvant treatments has been reported in cases of recalcitrant stenosis or strictures with evidence of dysphagic symptoms. Corticosteroids (either systemically or locally injected), the local application of mitomycin C, diathermy and laser ES sectioning have been reported. Some authors have suggested that stenting can reduce both the number of dilations and the treatment length. In many cases, this strategy is effective when either metallic or plastic stents are utilized. Treatment complications, such esophageal perforations, can be conservatively managed, considering surgery only in cases with severe pleural cavity involvement. In cases of stricture relapse, even if such relapses occur following the execution of well

The purpose of this review was to develop recommendations for the management of spinal disorders in low-income communities, with a focus on non-invasive pharmacological and non-pharmacological therapies for non-specific low back and neck pain. We synthesized two evidence-based clinical practice guidelines for the management of low back and neck pain. Our recommendations considered benefits, harms, quality of evidence, and costs, with attention to feasibility in medically underserved areas and low- and middle-income countries. Clinicians should provide education and reassurance, advise patients to remain active, and provide information about self-care options. For acute low back and neck pain without serious pathology, primary conservative treatment options are exercise, manual therapy, superficial heat, and nonsteroidal anti-inflammatory drugs (NSAIDs). For patients with chronic low back and neck pain without serious pathology, primary treatment options are exercise, yoga, cognitive behavioral therapies, acupuncture, biofeedback, progressive relaxation, massage, manual therapy, interdisciplinary rehabilitation, NSAIDs, acetaminophen, and antidepressants. For patients with spinal pain with radiculopathy, clinicians may consider exercise, spinal manipulation, or NSAIDs; use of other interventions requires extrapolation from evidence regarding effectiveness for non-radicular spinal pain. Clinicians should not offer treatments that are not effective, including benzodiazepines, botulinum toxin injection, systemic corticosteroids, cervical collar, electrical muscle stimulation, short-wave diathermy, transcutaneous electrical nerve stimulation, and traction. Guidelines developed for high-income settings were adapted to inform a care pathway and model of care for medically underserved areas and low- and middle-income countries by considering factors such as costs and feasibility, in addition to benefits, harms, and the quality of underlying evidence.

To review prospectively the intraoperative, short and medium term outcomes of patients treated by rollerball endometrial ablation during the learning curve for this relatively new procedure. Seventy-seven women with menorrhagia (71 with dysfunctional bleeding; six with additional small intramural myomas) underwent hysteroscopic rollerball endometrial ablation by coagulation diathermy during 1.5% glycine irrigation, after a two-month period of hormonal suppression. OPERATIVE AND SHORT-TERM EFFECTS: These were recorded at operation and six-week follow-up. No serious short-term complications were recorded. Objective measurement of intraoperative blood loss was always less than 20 mL. One woman experienced uterine perforation with a narrow cervical dilator which did not interfere with the ablation, and two patients had mild postoperative uterine infections. One patient experienced persistent postoperative pain. MEDIUM-TERM OUTCOME: This was recorded at each visit, or by telephone, and confirmed by questionnaire at one year. Twenty-five per cent achieved complete amenorrhoea, 29% staining only, 30% light periods, 10% "normal" or erratic periods and 6% were unchanged. Five patients underwent a second ablation, and three of these later underwent hysterectomy. Measured menstrual blood loss fell from 104 +/- 19 mL (mean +/- standard error of mean) to 1.7 +/- 1.1 mL at six months in 18 women. Other menstrual symptoms were also often dramatically reduced. Of those women with dysmenorrhoea, 33% were cured and 43% markedly improved; of those with midcycle pain, 28% were cured and 53% markedly improved; of those with significant premenstrual symptoms, 13% were cured, 47% markedly improved, 11% unchanged, and 6% were worse. This new procedure is a safe and effective treatment for menorrhagia caused by dysfunctional uterine bleeding, with impressive ancillary benefits for dysmenorrhoea, midcycle pain and premenstrual tension. It is often called minimally invasive surgery, but it

AIM: To demonstrate the value of Diosmin (flavonidic fraction) in the management of post-haemorhoidectomic symptoms. METHODS: Eighty-six consecutive patients with grades III and IV acute mixed hemorrhoids admitted to the Anorectal Surgical Department of First Affiliated Hospital, Xinjiang Medical University from April 2009 to April 2010, were enrolled in this study. An observer-blinded, randomized trial was conducted to compare post-haemorhoidectomic symptoms with use of Diosmin flavonidic fraction vs placebo. Eighty-six patients were randomly allocated to receive Diosmin flavonidic fraction 500 mg for 1 wk (n = 43) or placebo (n = 43). The Milligan-Morgan open haemorrhoidectomy was performed by a standardized diathermy excision method. Pain, bleeding, heaviness, pruritus, wound edema and mucosal discharge were observed after surgery. The postoperative symptoms and hospitalization time were recorded. RESULTS: The mean age of the Diosmin group and controls was 53.2 and 51.3 years, respectively. In Diosmin group, haemorrhoid piles were of the third degree in 33 patients and the fourth degree in 10; and in the control group, 29 were of the third degree and 14 were of the fourth degree. There was no statistically significance in age, gender distribution, degree and number of excised haemorrhoid piles, and the mean duration of haemorrhoidal disease between the two groups. There was a statistically significant improvement in pain, heaviness, bleeding, pruritus from baseline to the 8th week after operation (P < 0.05). Patients taking Diosmin had a shorter hospitalization stay after surgery (P < 0.05). There was also a significant improvement on the proctoscopic appearance (P < 0.001). However, there was no statistical difference between the two groups in terms of wound mucosal discharge. Two patients experienced minor bleeding at the 8th week in Diosmin group, and underwent surgery. CONCLUSION: Diosmin is effective in alleviating postoperational symptoms of haemorrhoids

ABSTRACT Background: Stapled hemorrhoidopexy is associated with less postoperative pain and faster recovery. However, it may be associated with a greater risk of symptomatic recurrence. We hypothesized that undertaking a limited surgical excision of hemorrhoid disease after stapling may be a valid approach for selected patients. Aim: To compare long-term results after stapled hemorrhoidopexy with and without complementation with closed excisional technique. Method: In a retrospective uni-institutional cohort study, sixty-five (29 men) patients underwent stapled hemorrhoidopexy and 21 (13 men) underwent stapled hemorrhoidopexy with excision. The same surgeons operated on all cases. Patients underwent stapled hemorrhoidectomy associated with excisional surgery if symptoms attributable to external hemorrhoid piles were observed preoperatively, or if residual prolapse or bulky external disease was observed after the firing of the stapler. A closed excisional diathermy hemorrhoidectomy without vascular ligation was utilized in all complemented cases. All clinical variables were obtained from a questionnaire evaluation obtained through e-mail, telephone interview, or office follow-up. Results: The median duration of postoperative follow-up was 48.5 (6-40) months. Patients with grades 3 and 4 hemorrhoid disease were operated on more frequently using stapled hemorrhoidopexy complemented with excisional technique (95.2% vs. 55.4%, p=0.001). Regarding respectively stapled hemorrhoidopexy and stapled hemorrhoidopexy complemented with excision, there was no difference between the techniques in relation to symptom recurrence (43% and 33%, p=0.45) and median interval between surgery and symptom recurrence (30 (8-84) and 38.8 (8-65) months, p=0.80). Eight (12.3%) patients were re-operated after stapled hemorrhoidopexy and 2 (9.6%), after hemorrhoidopexy with excision (p=0.78). Patient distribution in both groups according to the degree of postoperative satisfaction was similar (p

Branchial cleft anomalies are the second most common head and neck congenital lesions seen in children. Amongst the branchial cleft malformations, second cleft lesions account for 95% of the branchial anomalies. This article analyzes all the cases of branchial cleft anomalies operated on at Great Ormond Street Hospital over the past 10 years. All children who underwent surgery for branchial cleft sinus or fistula from January 2000 to December 2010 were included in this study. In this series, we had 80 patients (38 female and 42 male). The age at the time of operation varied from 1 year to 14 years. Amongst this group, 15 patients had first branchial cleft anomaly, 62 had second branchial cleft anomaly and 3 had fourth branchial pouch anomaly. All the first cleft cases were operated on by a superficial parotidectomy approach with facial nerve identification. Complete excision was achieved in all these first cleft cases. In this series of first cleft anomalies, we had one complication (temporary marginal mandibular nerve weakness. In the 62 children with second branchial cleft anomalies, 50 were unilateral and 12 were bilateral. In the vast majority, the tract extended through the carotid bifurcation and extended up to pharyngeal constrictor muscles. Majority of these cases were operated on through an elliptical incision around the external opening. Complete excision was achieved in all second cleft cases except one who required a repeat excision. In this subgroup, we had two complications one patient developed a seroma and one had incomplete excision. The three patients with fourth pouch anomaly were treated with endoscopic assisted monopolar diathermy to the sinus opening with good outcome. Branchial anomalies are relatively common in children. There are three distinct types, first cleft, second cleft and fourth pouch anomaly. Correct diagnosis is essential to avoid inadequate surgery and multiple procedures. The surgical approach needs to be tailored to the type

A review of the literature regarding the potential interactions between physiotherapy modalities and CRDs was performed. Next, a 2 year retrospective analysis of patient encounters at a physiotherapy facility was conducted. In addition, seven international physiotherapy societies and four CRD manufacturers were surveyed with respect to recommendations regarding physiotherapy treatments in device patients. The local physiotherapy facility treated 25 patients with CRD (22 pacemaker and 3 ICD patients) for a total of 230 visits (9.2 visits/patient). Five patients received transcutaneous electrical nerve stimulation (TENS) and all 25 were administered additional treatment in the form of ultrasound (15), acupuncture (19), Laser (7), traction/manual therapy (12), exercise (8), education (18), taping (5), and/or moist heat (5). No complications occurred. Meanwhile, international societies and device manufacturers offered few specific or consistent recommendations. There are no specific international policies regarding the administration of physiotherapy modalities in CRD patients and, thus, there are no specific guidelines to be implemented at the local level. Review of the literature and of recommendations from CRD manufacturers suggests that TENS, Diathermy, and Interferential Electrical Current Therapy

The contamination levels in city air were largely comparable with those seen after ultrasonic scalpel use. Although hydrocarbon concentrations are low, cumulative exposures may increase health risks. Where concerns arise, ultrasonic scalpel dissection may be preferable.

Background and study aims  The evidence for efficacy and safety of cold snare polypectomy is limited. The aim of this study was to assess the completeness of resection and safety of cold snare polypectomy, using either traditional or dedicated cold snares. Patients and methods  This was a prospective, non-randomized study performed at a single tertiary hospital. Adult patients with at least one colorectal polyp (size ≤ 10 mm) removed by cold snare were included. In the first phase, all patients had polyps removed by traditional snare without diathermy. In the second phase, all patients had polyps removed by dedicated cold snare. Complete endoscopic resection was determined from histological examination of quadrantic polypectomy margin biopsies. Immediate or delayed bleeding within 2 weeks was recorded. Results  In total, 181 patients with 299 eligible polyps (n = 93 (173 polyps) traditional snare group, n = 88 (126 polyps) dedicated cold snare group) were included. Patient demographics and procedure indications were similar between groups. Mean polyp size was 6 mm in both groups ( P  = 0.25). Complete polyp resection was 165 /173 (95.4 %; 95 %CI 90.5 – 97.6 %) in the traditional snare group and 124/126 (98.4 %; 95 %CI 93.7 – 99.6 %) in the dedicated cold snare group ( P  = 0.16). Serrated polyps, compared with adenomatous polyps, had a higher rate of incomplete resection (7 % vs. 2 %, P  = 0.03). There was no statistically significant difference in the rate of immediate bleeding (3 % vs. 1 %, P  = 0.41) and there were no delayed hemorrhages or perforations. Conclusions  Cold snare polypectomy is effective and safe for the complete endoscopic resection of small (≤ 10 mm) colorectal polyps with either traditional or dedicated cold snares. PMID:29250580

Observing surgical procedures is a beneficial educational experience for medical students during their surgical placements. Anecdotal evidence suggests that operating theatre related syncope may have detrimental effects on students' views of this. Our study examines the frequency and causes of such syncope, together with effects on career intentions, and practical steps to avoid its occurrence. All penultimate and final year students at a large UK medical school were surveyed using the University IT system supplemented by personal approach. A 20-item anonymous questionnaire was distributed and results were analysed using the Statistical Package for Social Sciences, version 15.0 (Chicago, Illinois, USA). Of the 630 clinical students surveyed, 77 responded with details of at least one near or actual operating theatre syncope (12%). A statistically significant gender difference existed for syncopal/near-syncopal episodes (male 12%; female 88%), p < 0.05. Twenty-two percent of those affected were graduate entry medical course students with the remaining 78% undergraduate. Mean age was 23-years (range 20 - 45). Of the 77 reactors, 44 (57%) reported an intention to pursue a surgical career. Of this group, 7 (9%) reported being discouraged by syncopal episodes in the operating theatre. The most prevalent contributory factors were reported as hot temperature (n = 61, 79%), prolonged standing (n = 56, 73%), wearing a surgical mask (n = 36, 47%) and the smell of diathermy (n = 18, 23%). The most frequently reported measures that students found helpful in reducing the occurrence of syncopal episodes were eating and drinking prior to attending theatre (n = 47, 61%), and moving their legs whilst standing (n = 14, 18%). Our study shows that operating theatre related syncope among medical students is common, and we establish useful risk factors and practical steps that have been used to prevent its occurrence.

To review scientific literature studying the effectiveness of physical therapy and electrophysical modalities for carpal tunnel syndrome (CTS). The Cochrane Library, PubMed, Embase, CINAHL, and Physiotherapy Evidence Database. Two reviewers independently applied the inclusion criteria to select potential eligible studies. Two reviewers independently extracted the data and assessed the methodologic quality using the Cochrane Risk of Bias Tool. A best-evidence synthesis was performed to summarize the results of the included studies (2 reviews and 22 randomized controlled trials [RCTs]). For physical therapy, moderate evidence was found for myofascial massage therapy versus ischemic compression on latent, or active, trigger points or low-level laser therapy in the short term. For several electrophysical modalities, moderate evidence was found in the short term (ultrasound vs placebo, ultrasound as single intervention vs other nonsurgical interventions, ultrasound vs corticosteroid injection plus a neutral wrist splint, local microwave hyperthermia vs placebo, iontophoresis vs phonophoresis, pulsed radiofrequency added to wrist splint, continuous vs pulsed vs placebo shortwave diathermy, and interferential current vs transcutaneous electrical nerve stimulation vs a night-only wrist splint). In the midterm, moderate evidence was found in favor of radial extracorporeal shockwave therapy (ESWT) added to a neutral wrist splint, in favor of ESWT versus ultrasound, or cryo-ultrasound, and in favor of ultrasound versus placebo. For all other interventions studied, only limited, conflicting, or no evidence was found. No RCTs investigating the long-term effects of physical therapy and electrophysical modalities were found. Because of heterogeneity in the treatment parameters used in the included RCTs, optimal treatment parameters could not be identified. Moderate evidence was found for several physical therapy and electrophysical modalities for CTS in the short term and midterm

Squamous-cell Carcinoma of the Anus and Anal Canal: An Analysis of 55 Cases

The analysis is of 55 cases admitted into St. Mark's Hospital from 1922 to 1940. The incidence was 3.35% of all cases of cancer of the rectum, anal canal and anus admitted during this period. Sex distribution—27 males and 28 females. The average age (61.7 years) is higher than that of columnar-cell carcinoma of the rectum (57.4 years). Histology.—The cases have been graded into three grades of malignancy—low grade, medium grade, and high grade. Low grade squamous carcinoma is twice as frequent in men as in women, and generally originates at the anal margin. Medium grade squamous carcinoma is equally distributed between men and women; it may arise at the anus or in the anal canal. High grade squamous carcinoma is much more common in the female sex and is almost entirely limited to the anal canal. Quadrant affected—about one-third of the anal margin growths and one-half of the anal canal growths were situated anteriorly. Differential diagnosis from simple papilloma, simple ulcer, chronic inflammation, tuberculous ulcer, tuberculide, primary chancre, amœbic ulcer, basal-cell carcinoma, columnar-cell carcinoma. Biopsy and grading essential before treatment is decided upon. The results of treatment in the three grades of malignancy are described. The best results were obtained in the early low-grade cases treated by interstitial radium needling. In the medium and high grades only three five-year survivals can be reported and these followed excision of the rectum. The management of the inguinal glands is discussed and the importance of a very close post-operative supervision emphasized. Squamous carcinoma of the anal canal may cause lymphatic metastases in the superior hæmorrhoidal glands; there have been four such cases in this series. Diathermy perineal excision is indicated in these cases. ImagesFig. 1Fig. 2Fig. 3Fig. 5Fig. 6aFig. 6bFig. 7Fig. 1Fig. 2Fig. 3Fig. 4 PMID:19992316

Whiplash-associated disorders (WAD) and neck pain and associated disorders (NAD) are prevalent conditions that impact society and impose a significant economic burden on health-care systems. Health economic evidence on WAD and NAD interventions has been sparse: only three economic evaluations of interventions for NAD were identified by the Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders (NPTF). An updated overview is needed to inform health-care policy and guidelines. This study aimed to determine the cost-effectiveness of interventions for grades I-III WAD and NAD in children and adults. Systematic review of health economic literature, best-evidence synthesis. We systematically searched CINAHL, the Cochrane economic databases (Health Technology Assessment, NHS Economic Evaluation Database), EconLit, EMBASE, MEDLINE, PsycINFO, and Tufts CEA Registry from 2000 to 2015 for economic evaluations of WAD and NAD interventions. We appraised relevant evaluations using the Scottish Intercollegiate Guidelines Network Methodology Criteria for Economic Evaluations. We extracted data, including mean costs (standardized to 2013 Canadian dollars [CAD]) and quality-adjusted life years (QALYs), from studies with adequate methodological quality. We recalculated cost-effectiveness statistics based on the standardized currency using a willingness-to-pay of CAD $50,000 per additional QALY. Funding was provided by the Ministry of Finance. Our search identified 1,616 citations. Six studies fulfilled our selection criteria, including three studies previously reviewed by the NPTF. Structured education appears cost-effective for adults with WAD. For adults with NAD, acupuncture added to routine medical care; manual therapy; multimodal care that includes manual therapy; advice and exercise; and psychological care using cognitive-behavioral therapy appear cost-effective. In contrast, adding manual therapy or diathermy to advice and exercise; multimodal

In Italy the prevalence of genital warts in women (15-64 years) is approximately 0.6% with an incidence of 0.4% per year. Treatments for GW are usually long, with moderate success and high costs. The aim of the study was to evaluate the diagnostic-therapeutic pathway, duration and setting of treatment, costs of episodes of condyloma in a population attending a regional STI clinic in Piedmont. This was a retrospective observational study conducted using medical records of outpatients who first visited the STI Clinic of San Lazzaro Dermatological Hospital in 2008. The patients' medical histories were analysed for episodes that occurred and were cleared in 18 months following the initial visit. Data on screening methods for STIs, type of diagnosis for condyloma, treatment type, treatment setting, and anatomic lesion site were obtained from medical records. The costs were calculated for each episode. A total of 450 episodes were analysed (297 men,153 women). The most frequently affected anatomic site was the genital area (74%) in both genders. With regard to treatment setting, 78.44% of patients received outpatient treatment at the STI clinic, 4% were treated at home, and 0.22% were hospitalised; 11.11% were treated in multiple settings. The mean number of treatments per episode was 2.03; although many patients received only 1 treatment (n = 207, 46%), exspecially cryotherapy or diathermy coagulation (64.73% versus 28.02% of episodes, respectively). The mean episode duration was 80.74 days. The mean cost (in 2011 euros) for an episode was €158.46 ± 257.77; the mean costs were €79.13 ± 57.40 for diagnosis and €79.33 ± 233.60 for treatment. The mean cost for treatment in a STI-Clinic setting was €111.39 ± 76.72, that for home treatment was €160.88 ± 95.69, and that for hospital care was €2825.94. The treatment of and associated costs for genital warts are significant. Several factors affect the cost, and internal STI clinic

Up to one third of the general population suffers from symptoms caused by hemorrhoids. Conservative treatment comes first unless the patient presents with an acute hemorrhoidal prolapse or a thrombosis. A fiber enriched diet is the primary treatment option, recommended in the perioperative period as well as a long-term prophylaxis. A timely limited application of topical ointments or suppositories and/or flavonoids are further treatment options. When symptoms persist interventional procedures for grade I-II hemorrhoids, and surgery for grade III-IV hemorrhoids should be considered. Rubber band ligation is the interventional treatment of choice. A comparable efficacy using sclerosing or infrared therapy has not yet been demonstrated. We therefore do not recommend these treatment options for the cure of hemorrhoids. Self-treatment by anal insertion of bougies is of lowrisk and may be successful, particularly in the setting of an elevated sphincter pressure. Anal dilation, sphincterotomy, cryosurgery, bipolar diathermy, galvanic electrotherapy, and heat therapy should be regarded as obsolete given the poor or missing data reported for these methods. For a long time, the classic excisional hemorrhoidectomy was considered to be the gold standard as far as surgical procedures are concerned. Primary closure (Ferguson) seems to be superior compared to the "open" version (Milligan Morgan) with respect to postoperative pain and wound healing. The more recently proposed stapled hemorrhoidopexy (Longo) is particularly advisable for circular hemorrhoids. Compared to excisional hemorrhoidectomy the Longo-operation is associated with reduced postoperative pain, shorter operation time and hospital stay as well as a faster recovery, with the disadvantage though of a higher recurrence rate. Data from Hemorrhoidal Artery Ligation (HAL)-, if appropriate in combination with a Recto-Anal Repair (HAL/RAR)-, demonstrates a similar trend towards a better tolerance of the procedure at the

Purpose Surgical punctal occlusion is indispensable for the treatment of severe dry eye in cases where punctal-plug insertion is not applicable due to an enlarged or deformed punctum. However, permanent punctal occlusion is difficult in some cases. In our aim to establish a more reliable punctal occlusion, we have devised a new surgical approach for punctal occlusion. Patients and methods This study involved 20 puncta of 12 eyes of 12 patients (1 male and 11 females; mean age: 65.2 years) with severe aqueous-tear-deficient dry eye. A new surgical procedure for punctal occlusion using fibrous tissue from under the lacrimal caruncle into the diathermy-induced deepithelialized canaliculus as supporting tissue for punctal closure was performed. In all patients, the assessment of eye symptoms, as well as the condition of punctal occlusion by slit-lamp biomicroscopy, tear volume (tear-meniscus radius [TMR] measurement by meniscometry), the condition of precorneal tear film (graded by interferometry [IG]), measurement of fluorescein breakup time (FBUT), and scoring of ocular surface staining (fluorescein score of area [FSA] and density [FSD], and lissamine green score [LGS]) were performed, and the preoperative and 6-month-postoperative values were compared. Results In regard to the postoperative improvement of symptoms, 11 patients showed remarkable improvement, 1 patient showed improvement, and no reopening of the closed punctum was found in any patient. Test values were all significantly improved post surgery (all: P<0.05) as compared to those prior to surgery (respective values [mean ± SD], and the pre- and postoperative P-values were: TMR (mm) [0.18±0.08; 0.56±0.28, P=0.002], IG [4.3±0.9; 2.7±0.8, P=0.009], FBUT [0.4±0.6; 4.1±2.9, P=0.004], FSA [1.6±0.7; 0.7±0.9, P=0.03], FSD [2.7±0.7; 0.6±0.7, P=0.003], and LGS [5.1±2.7; 1.1±2.1, P=0.005]).

Patients suffering from osteoarthritis of the knee and patients post total knee arthroplasty often develop refractory, disabling chronic knee pain. Radiofrequency ablation, including conventional, pulsed, and cooled, has recently become more accepted as an interventional technique to manage chronic knee pain in patients who have failed conservative treatment or who are not suitable candidates for surgical treatment. This systematic review aimed to analyze published studies on radiofrequency ablation to provide an overview of the current knowledge regarding variations in procedures, nerve targets, adverse events, and temporal extent of clinical benefit. A systematic review of published studies investigating conventional, pulsed, or cooled radiofrequency ablation in the setting of chronic knee pain. Medline, Google Scholar, and the Cochrane Central Register of Controlled Trials (CENTRAL) databases were reviewed for studies on radiofrequency ablation for patients with chronic knee pain through July 29, 2016. From the studies, the procedural details, outcomes after treatment, follow-up points, and complications were compiled and analyzed in this literature review. Included studies were analyzed for clinical relevance and strength of evidence was graded using either the NHLBI Quality assessment of controlled intervention studies or the NHLBI quality assessment for before-after (pre-post) studies with no control group. Seventeen total publications were identified in the search, including articles investigating conventional, pulsed, or cooled radiofrequency ablation. These studies primarily targeted either the genicular nerves or used an intraarticular approach. Of the studies, 5 were small-sized randomized controlled trials, although one involved diathermy radiofrequency ablation. There were 8 retrospective or prospective case series and 4 case reports. Utilizing the strength of evidence grading, there is a low level of certainty to suggest a superior benefit between

The mean pain score at four weeks was 51 points with placebo plus exercise, while with LLLT plus exercise the mean pain score was 32 points on a 100 point scale (mean difference (MD) 19 points, 95% CI 15 to 23; absolute risk difference 19%, 95% CI 15% to 23%). The mean function impairment score was 48 points with placebo plus exercise, while with LLLT plus exercise the mean function impairment score was 36 points on a 100 point scale (MD 12 points, 95% CI 6 to 18; absolute risk difference 12%, 95% CI 6 to 18). Mean active abduction was 70 degrees with placebo plus exercise, while with LLLT plus exercise mean active abduction was 79 degrees (MD 9 degrees, 95% CI 2 to 16; absolute risk difference 5%, 95% CI 1% to 9%). No participants in either group reported adverse events. LLLT's benefits on function were maintained at four months.Based on very low quality evidence from six trials, we were uncertain whether therapeutic ultrasound, PEMF, continuous short wave diathermy, Iodex phonophoresis, a combination of Iodex iontophoresis with continuous short wave diathermy, or a combination of therapeutic ultrasound with transcutaneous electrical nerve stimulation (TENS) were effective adjuncts to exercise. Based on low or very low quality evidence from 12 trials, we were uncertain whether a diverse range of electrotherapy modalities (delivered alone or in combination with manual therapy, exercise, or other active interventions) were more or less effective than other active interventions (for example glucocorticoid injection). Based upon low quality evidence from one trial, LLLT for six days may be more effective than placebo in terms of global treatment success at six days. Based upon moderate quality evidence from one trial, LLLT plus exercise for eight weeks may be more effective than exercise alone in terms of pain up to four weeks, and function up to four months. It is unclear whether PEMF is more or less effective than placebo, or whether other

% more). Between-group differences were not important at nine months. No participant reported adverse events.Therapeutic ultrasound produced no clinically important additional benefits when combined with other physical therapy interventions (eight clinically heterogeneous trials, low quality evidence). We are uncertain whether there are differences in patient-important outcomes between ultrasound and other active interventions (manual therapy, acupuncture, glucocorticoid injection, glucocorticoid injection plus oral tolmetin sodium, or exercise) because the quality of evidence is very low. Two placebo-controlled trials reported results favouring LLLT up to three weeks (low quality evidence), however combining LLLT with other physical therapy interventions produced few additional benefits (10 clinically heterogeneous trials, low quality evidence). We are uncertain whether transcutaneous electrical nerve stimulation (TENS) is more or less effective than glucocorticoid injection with respect to pain, function, global treatment success and active range of motion because of the very low quality evidence from a single trial. In other single, small trials, no clinically important benefits of pulsed electromagnetic field therapy (PEMF), microcurrent electrical stimulation (MENS), acetic acid iontophoresis and microwave diathermy were observed (low or very low quality evidence).No adverse events of therapeutic ultrasound, LLLT, TENS or microwave diathermy were reported by any participants. Adverse events were not measured in any trials investigating the effects of PEMF, MENS or acetic acid iontophoresis. Based on low quality evidence, therapeutic ultrasound may have short-term benefits over placebo in people with calcific tendinitis, and LLLT may have short-term benefits over placebo in people with rotator cuff disease. Further high quality placebo-controlled trials are needed to confirm these results. In contrast, based on low quality evidence, PEMF may not provide clinically

Our review adds new evidence to the Neck Pain Task Force and suggests that mobilization, manipulation, and clinical massage are effective interventions for the management of neck pain. It also suggests that electroacupuncture, strain-counterstrain, relaxation massage, and some passive physical modalities (heat, cold, diathermy, hydrotherapy, and ultrasound) are not effective and should not be used to manage neck pain.

Resource use was estimated from clinical advisors and combined with quality-adjusted life-years obtained through mapping to present tentative cost-effectiveness results. Thirty-one clinical effectiveness studies and one economic evaluation were included. The clinical effectiveness studies evaluated steroid injection, sodium hyaluronate, supervised neglect, physical therapy (mainly physiotherapy), acupuncture, MUA, distension and capsular release. Many of the studies identified were at high risk of bias. Because of variation in the interventions and comparators few studies could be pooled in a meta-analysis. Based on single RCTs, and for some outcomes only, short-wave diathermy may be more effective than home exercise. High-grade mobilisation may be more effective than low-grade mobilisation in a population in which most patients have already had treatment. Data from two RCTs showed that there may be benefit from adding a single intra-articular steroid injection to home exercise in patients with frozen shoulder of < 6 months' duration. The same two trials showed that there may be benefit from adding physiotherapy (including mobilisation) to a single steroid injection. Based on a network of nine studies the MTC found that steroid combined with physiotherapy was the only treatment showing a statistically and clinically significant beneficial treatment effect compared with placebo for short-term pain (standardised mean difference -1.58, 95% credible interval -2.96 to -0.42). This analysis was based on only a subset of the evidence, which may explain why the findings are only partly supportive of the main analysis. No studies of patients' views about the treatments were identified. Average costs ranged from £36.16 for unguided steroid injections to £2204 for capsular release. The findings of the

immobilisation, but another showed using a backslab improved ankle dorsiflexion range of motion compared with using a bandage.Five studies investigated different rehabilitation interventions following the immobilisation period after either conservative or surgical orthopaedic management. There was no evidence of effect for stretching or manual therapy in addition to exercise, or exercise compared with usual care. One small study (14 participants) at a high risk of bias found reduced ankle swelling after non-thermal compared with thermal pulsed shortwave diathermy. There is limited evidence supporting early commencement of weight-bearing and the use of a removable type of immobilisation to allow exercise during the immobilisation period after surgical fixation. Because of the potential increased risk of adverse events, the patient's ability to comply with the use of a removable type of immobilisation to enable controlled exercise is essential. There is little evidence for rehabilitation interventions during the immobilisation period after conservative orthopaedic management and no evidence for stretching, manual therapy or exercise compared to usual care following the immobilisation period. Small, single studies showed that some electrotherapy modalities may be beneficial. More clinical trials that are well-designed and adequately-powered are required to strengthen current evidence.
