Pulsed Shortwave Diathermy and Prolonged Long-Duration Stretching Increase Dorsiflexion Range of Motion More Than Identical Stretching Without Diathermy.

OBJECTIVE: To compare the effects of 3 treatments on ankle dorsiflexion range of motion: prolonged long-duration stretching, pulsed shortwave diathermy followed by stretching, and pulsed shortwave diathermy, stretching, and ice combined. DESIGN AND SETTING: A 2 x 5 x 15 repeated-measures (on 2 factors) design guided this study. Range-of-motion change in triceps surae flexibility was the dependent variable. The 3 independent variables were treatment group, pretest and posttest measurements, and day. Treatment group had 4 levels: control, stretching (10 minutes of stretching via the weight and pulley), diathermy and stretching (20 minutes of diathermy and 10 minutes of stretching), and diathermy, stretching, and ice (20 minutes of diathermy, 10 minutes of stretching applied after 15 minutes of diathermy, and 5 minutes of ice applied during the last 5 minutes of stretching). Each subject received 14 treatments throughout 3 weeks, with a follow-up measurement taken 6 days after the last treatment. SUBJECTS: Forty-four healthy college-student volunteers not involved in any flexibility program. MEASUREMENTS: We measured ankle dorsiflexion using a digital inclinometer before and after treatment. RESULTS: After 14 days of treatment, the range-of-motion increase was greater after heat and stretching than after stretching alone. After 6 additional days of rest, the heat and stretching range-of-motion increase was greater than that for stretching alone. CONCLUSION: Pulsed shortwave diathermy application before prolonged long-duration static stretching was more effective than stretching alone in increasing flexibility throughout 3 weeks. After 14 treatments, prolonged long-duration stretching combined with pulsed shortwave diathermy followed by ice application caused greater immediate and net range-of-motion increases than prolonged long-duration stretching alone.

Laparoscopic "drilling" by diathermy or laser for ovulation induction in anovulatory polycystic ovary syndrome.

BACKGROUND: Problems in inducing ovulation in women with polycystic ovary syndrome (PCOS) and anovulation (failure to ovulate) are well recognised. Surgical ovarian wedge resection was the first established treatment for anovulatory PCOS patients but was largely abandoned of the risk of post-surgical adhesion formation. It was replaced by medical ovulation induction with clomiphene and gonadotrophins. However patients with PCOS treated with gonadotrophins often have a polyfollicular response and are exposed to the risks of ovarian hyperstimulation syndrome (OHSS) and multiple pregnancy. Although effective, it is an expensive, stressful and time consuming form of treatment requiring intensive monitoring. A new surgical therapy, laparoscopic ovarian "drilling", may avoid or reduce the need, or facilitate the use, of gonadotrophins for inducing ovulation. The procedure can be done on an outpatient basis with less trauma and fewer postoperative adhesions. It has been claimed in many uncontrolled observational studies that it is followed, at least temporarily, by a high rate of spontaneous postoperative ovulation and conception, or that subsequent medical ovulation induction becomes easier. OBJECTIVES: To determine the effectiveness of laparoscopic ovarian drilling for ovulation induction in subfertile women with anovulation (failure to ovulate) and polycystic ovarian syndrome (PCOS). SEARCH STRATEGY: The search strategy of the Menstrual Disorders and Subfertility Group was used for the identification of randomised controlled trials (RCTS). A computerised MEDLINE search was used to identify non randomised controlled trials. SELECTION CRITERIA: Trials were eligible for inclusion if treatment consisted of laparoscopic ovarian drilling in order to induce ovulation in subfertile women with PCOS and compared with a concurrent control group. DATA COLLECTION AND ANALYSIS: Fourteen trials were identified; eight were included in the review of which seven were randomised. All trials were assessed for quality criteria. The main studied outcomes were ovulation and pregnancy rates. Miscarriage rate, multiple pregnancy rate, and incidence of overstimulation and ovarian hyperstimulation syndrome rate were secondary outcomes. MAIN RESULTS: With the exception of multiple pregnancy rates no differences were demonstrated for any of the interventions studied but the numbers of patients who have been randomised to controlled studies at this time is insufficient to conclude that laparoscopic ovarian drilling is more effective than gonadotrophin therapy for other outcomes. REVIEWER'S CONCLUSIONS: The value of laparoscopic ovarian drilling as a primary treatment for subfertile patients with anovulation (failure to ovulate) and polycystic ovarian syndrome (PCOS) is undetermined. There is insufficient evidence to determine a difference in ovulation or pregnancy rates when compared to gonadotrophin therapy as a secondary treatment for clomiphene resistant women. Multiple pregnancy rates are reduced in those women who conceive following laparoscopic drilling. None of the studied modalities of drilling technique had any obvious advantages.

The Carry-Over Effects of Diathermy and Stretching in Developing Hamstring Flexibility.

OBJECTIVE: To compare the effects of low-load, short-duration stretching with or without high-intensity, pulsed short-wave diathermy on hamstring flexibility. DESIGN AND SETTING: We used a single-blind, repeated-measures design (pretest and posttest for all treatments) that included a placebo. The 3 independent variables were treatment mode, pretest and posttest measurements, and day. Treatment mode had 3 levels: diathermy and stretching, stretching alone, and control. The dependent variable was range of motion. Subjects were randomly assigned to the diathermy and stretching, stretching-only, or control group. Subjects were treated and tested each day (at approximately the same time) for 5 days, with a follow-up test administered 72 hours later. Hamstring flexibility was tested using a sit-and-reach box before and after each treatment. Diathermy and stretching subjects received a 15-minute diathermy treatment on the right hamstring at a setting of 7000 pulses per second, with an average pulse width of 95 μsec. Stretching-only subjects received a 15-minute sham diathermy treatment. Both diathermy and stretching and stretching-only subjects then performed three 30-second stretches (short duration) before being retested. Control subjects lay prone for 15 minutes before being retested. SUBJECTS: Thirty-seven healthy college students (11 men, 26 women, age = 20.46 +/- 1.74 years) volunteered. MEASUREMENTS: Hamstring flexibility was measured using a sit-and-reach box before and after each treatment. RESULTS: The average increases in hamstring flexibility over the 5 treatment days for the diathermy and stretching, stretching-only, and control groups were 6.06 cm (19.6%), 5.27 cm (19.7%), and 3.38 cm (10.4%), respectively. Three days later (after no treatment), the values for the diathermy and stretching, stretching-only, and control groups were 8.27 cm (26.7%), 6.83 cm (25.3%), and 4.15 cm (14.2%), respectively. No significant differences in hamstring flexibility were noted among the groups. CONCLUSIONS: Diathermy and short-duration stretching were no more effective than short-duration stretching alone at increasing hamstring flexibility. The effects of diathermy with longer stretching times need to be researched.

Day-case stapled (circular) vs. diathermy hemorrhoidectomy: a randomized, controlled trial evaluating surgical and functional outcome.

PURPOSE: Stapled hemorrhoidectomy may be associated with less pain and faster recovery than conventional hemorrhoidectomy for prolapsing hemorrhoids. Therefore, the outcome of stapled hemorrhoidectomy was compared with that of diathermy hemorrhoidectomy in a randomized, controlled trial. METHODS: Sixty patients with third-degree hemorrhoids were randomly assigned to stapled hemorrhoidectomy (n = 30) or to diathermy hemorrhoidectomy in a day-case setting. Visual analog scale was used for postoperative pain scoring. Surgical and functional outcome was assessed at six weeks and one year after surgery. RESULTS: Operation time was a median of 21 (range, 11-59) minutes in the stapled group. 22 (range, 14-40) minutes in the diathermy group. Day-case surgery was successful in 24 patients (80 percent) in the stapled group vs. 29 patients (97 percent) in the diathermy group. Average pain in the stapled group was significantly lower than in the diathermy group (median, 1.8 (0.1-4.8) vs. 4.3 (1.4-6.2), 95 percent confidence interval difference medians, 1.15-3.85, P = 0.0002, Mann-Whitney U test) as was the average pain expected by the patients (median -2.7 (-0.15-0.8) vs. 0.006 (-4.05-0.5) respectively, 95 percent confidence interval difference medians, 0.5-3.55, P = 0.0018, Mann-Whitney U test). Postoperative morbidity and time off work were not significantly different between the diathermy and stapled groups. Seven treatment failures in the stapled group and one in the diathermy group necessitated other treatments at a later date. Patient satisfaction scores in the stapled and diathermy group were similar. Symptoms attributed to difficult rectal evacuation decreased significantly after surgery. CONCLUSIONS: Stapled hemorrhoidectomy is a significantly less painful operation than diathermy hemorrhoidectomy, but does not seem to offer significant advantages in terms of hospital stay or symptom control in the long term. Hemorrhoidectomy may improve symptoms of difficult rectal evacuation.

Post-operative morbidity following paediatric tonsillectomy; a comparison of bipolar diathermy dissection and blunt dissection.

In a prospective study of 76 children aged between 18 months and 13 years, 40 children underwent tonsillectomy using the traditional blunt dissection technique with bipolar diathermy to establish haemostasis while 36 children underwent tonsillectomy where bipolar diathermy alone was used to dissect out the tonsils. Blood loss was significantly reduced in the diathermy dissection group (10.5 ml +/- 2.05, diathermy dissection, 33.56 ml +/- 1.95, blunt dissection, P < 0.05). More analgesia was required in the diathermy dissection group prior to hospital discharge (P = 0.01). The diathermy dissection group took a significantly longer period of time to re-establish a normal diet (7.07 days +/- 0.44, diathermy dissection, 5.15 days +/- 0.36, blunt dissection, P = 0.001). Fifteen percent of children in the blunt dissection group and 31% in the diathermy dissection group were taken to the general practitioner between days 3-10 because of sore throat, poor oral intake or otalgia. Twenty two point four percent of children overall were prescribed antibiotics. This recently described technique of bipolar diathermy dissection could be a useful technique in selected cases such as the very small or those with a bleeding diathesis but is associated with increased postoperative morbidity and requires good postoperative analgesia.

Eliminating diathermy-induced artifacts during intraoperative monitoring of somatosensory-evoked potentials: a hardware solution.

Somatosensory-evoked potentials (SEPs) recorded intraoperatively are often contaminated by artifacts arising from unipolar diathermy. This increases variability in serial SEP recordings and decreases the reliability of SEPs for intraoperative monitoring. Rejection of single sweeps on the basis of a voltage criterion can only partially prevent the inclusion of sweeps containing artifacts. We describe a low-cost hardware system that will halt SEP acquisition automatically before diathermy becomes active. Activation of the diathermy switch will halt SEP acquisition by sending a digital inhibit signal to the evoked potential machine via a fiberoptic cable. A timer delays the activation of the diathermy until the last sweep has been completed. To allow the electroencephalographic amplifiers to recover from any overload condition resulting from the high-voltage/high-frequency input during diathermy, acquisition is resumed only after a user-selectable time interval. The system was evaluated in 50 patients. It effectively interrupted SEP acquisition each time diathermy was used. By eliminating diathermy noise from the averaged waveforms, the system will allow evoked potential monitoring even during periods of intensive use of diathermy.

Endoscopic diathermy in patients with cardiac pacemakers.

BACKGROUND AND STUDY AIMS: Malfunction of cardiac pacemakers related to diathermy in surgical procedures has been reported, but the risks of endoscopic diathermy in pacemaker patients is unknown. The aim of this study was to investigate current practice amongst British gastroenterologists regarding endoscopy in cardiac pacemaker patients. METHODS: An anonymous postal questionnaire survey of 634 members of the Endoscopy section of the British Society of Gastroenterology was conducted. RESULTS: 410/634 (65%) replied. Respondents conducted 59270 endoscopic retrograde cholangiopancreatography procedures (ERCPs) and 88544 colonoscopies per year. 77.3% of respondents were aware of the possibility of adverse interactions between diathermy and pacemakers. 74.2% enquired whether a pacemaker was present prior to endoscopy. In cases where patients were known to have pacemakers fitted, 23.9% recorded an electrocardiogram (ECG) prior to endoscopic diathermy, 36.2% conducted ECG monitoring during the procedure, 35.9% consulted a cardiologist or pacemaker technician and 13.4% carried out specific preventative measures. 4.1% of all respondents were aware of instances of pacemaker malfunction having occurred during endoscopic diathermy. CONCLUSION: Most gastroenterologists surveyed were aware of the possibility of adverse interactions between diathermy and cardiac pacemakers, but few undertook measures to detect or prevent pacemaker malfunction. Endoscopic diathermy in cardiac pacemaker patients, however, appears generally safe, although the endoscopist should be aware of the small chance of an adverse interaction.

The treatment of superficial bladder tumours under local anaesthetic using suction diathermy electrodes.

Daycase cystoscopy under local anaesthetic is commonly used in screening patients with superficial transitional cell carcinoma of the bladder. Treatment of any lesions found, however, often requires a further cystoscopy under general or regional anaesthesia. Recent reports suggest that small lesions can be diathermied without anaesthesia with only mild patient discomfort. Suction diathermy electrodes, introduced for the treatment of small superficial bladder tumours, have significant advantages over conventional methods. Firstly, most of the superficial tumour fronds can be removed painlessly by suction alone. Diathermy, the uncomfortable component of treatment, is sparingly used to treat the tumour base. Larger tumours can therefore be treated by suction diathermy, with less patient discomfort, than by standard cystodiathermy methods. Secondly, by eliminating tumour debris within the bladder during treatment and reducing tissue damage due to diathermy, suction diathermy minimizes the risk of tumour recurrence due to implantation. In this preliminary report the ease and efficacy of using suction diathermy electrodes under local anaesthesia is assessed.

A prospective study comparing unilateral and bilateral laparoscopic ovarian diathermy in women with the polycystic ovary syndrome.

OBJECT: To assess the efficacy of unilateral laparoscopic ovarian diathermy in the induction of ovulation in anti-estrogen-resistant polycystic ovary syndrome (PCOS). DESIGN: A prospective randomized study was performed to compare unilateral with bilateral ovarian diathermy. SETTING: Specialist Reproductive Endocrine Unit. PATIENTS: Ten patients with anti-estrogen-resistant PCOS. INTERVENTIONS: Randomization to unilateral (4 patients) or bilateral laparoscopic ovarian diathermy (6 patients). MAIN OUTCOME MEASURES: Rate and side of ovulation and change in endocrine profiles after ovarian diathermy. RESULTS: Unilateral ovarian diathermy resulted in ovulation from both ovaries. Fifty percent of the patients responded to diathermy and those who responded had a significantly greater fall in serum LH concentrations than those who failed to respond. CONCLUSIONS: The mechanism of action of laparoscopic ovarian diathermy is via a correction of disturbed ovarian-pituitary feedback. Hypersecretion of LH appears to be the most significant endocrine disturbance in these patients.

The effects of different levels of heat production induced by diathermy and eccentric work on thermoregulation during exercise at a given skin temperature.

The thermal responses of two healthy male subjects have been studied at the same mean skin temperature (Tsk) during negative work, positive work and positive work in which additional heating was induced by diathermy. The results showed that for a given metabolic heat production (M) rectal (Tre) and oesophageal (Toes) temperatures were higher in negative work and positive work with diathermy than normal control experiments. In resting experiments with diathermy, Toes rose to the same level as when an equal amount of heat was produced metabolically by exercise. In negative work and positive work with diathermy sweat loss (Msw) was higher for a given M and Tsk than found for normal exercise, but in all three forms of work the relationship of Msw to total heat production (H) was identical. During positive work with and without diathermy the differences in Msw could be accounted for by using a previously developed model of relative sweating rate: %Msw = -constant + alphaTre (or Toes) + betaTsk. In negative work, removal of the difference between predicted and observed %Msw required the inclusion of a further factor into the equation based on muscle temperature. The results suggest that the core temperature in exercise rises to meet the requirements of heat dissipation mainly by stimulating Msw and establishing a heat transfer gradient from core to periphery and is not necessarily or uniquely related to M or to the rate of working. The study underlines the usefulness of negative work and diathermy as physiological tools for the further understanding of thermoregulation during exercise.

Transscleral diathermy: an additional tool in the management of retinal detachment due to posterior breaks in highly myopic eyes.

PURPOSE: To investigate the usefulness of transscleral diathermy for the treatment of retinal detachment due to breaks located at the posterior pole in areas of advanced chorioretinal atrophy or staphyloma in highly myopic eyes. METHODS: We reviewed the charts of seven consecutive patients who were operated on between 1984 and 1994 and for whom transscleral diathermy was used during intraocular retinal reattachment surgery to reduce posterior staphyloma. Mean refraction of the seven eyes was -24 diopters (range -16 to -35 diopters). RESULTS: After surgery, which included diathermy, the retina was reattached in six eyes (86%) that also had undergone vitrectomy and silicone oil tamponade, but remained detached in one eye (14%) that had undergone pneumopexy and diathermy; in this eye, the retina was subsequently reattached after vitrectomy and silicone oil injection. Silicone oil was removed from all seven eyes after a mean duration of 2.5 months. During a mean follow-up of 3 years, a recurrent retinal detachment developed in one eye 8 months after silicone oil removal. This retina was reattached after reinjection of silicone oil. CONCLUSIONS: In the treatment of retinal detachment in highly myopic eyes, closure of posterior holes in areas of advanced chorioretinal atrophy or staphyloma can be achieved by transscleral diathermy in conjunction with vitrectomy and temporary silicone oil tamponade. The main benefit of transscleral diathermy results from its posterior pole scleral buckling effect due to shrinkage of the sclera.

Scleral damage: comparison of standard and modified diathermy electrodes.

Full-thickness scleral diathermy using a standard electrode causes significant scleral damage and necrosis. Use of a modified (Jabbour's) diathermy electrode appears to cause minimal scleral damage. We evaluated the scleral changes following transscleral diathermy application using standard and modified diathermy electrodes to the peripheral retina and ciliary body. Twelve Dutch belted pigment rabbits were used in our experiment. Three eyes each were subjected to transscleral diathermy using standard and modified electrodes to produce chorioretinal scars and cyclodestruction. Eyes were examined with the slit lamp and indirect ophthalmoscope at weekly intervals for 4 weeks. Light and transmission electron microscopy was performed 1 hour after diathermy application in 4 animals and in the remaining 8 animals at 4 weeks. Chorioretinal scarring and ciliary body atrophy were successfully induced with both types of electrodes. However, scleral damage was less severe in eyes treated with the modified electrode as compared with the standard electrode.

Diathermy loop excision in the management of cervical intraepithelial neoplasia: diagnosis and treatment in one procedure.

OBJECTIVE: Diathermy loop excision was performed as a new diagnostic-treatment in patients with cervical cytologic diagnoses consistent with an epithelial abnormality. STUDY DESIGN: A total of 424 patients with cervical cytologic diagnoses consistent with an epithelial abnormality, but macroscopically or colposcopically not consistent with invasive carcinoma, were subjected to diathermy loop excision to diagnose and treat cervical lesions in one procedure. RESULTS: The diagnostic accuracy rate was 99%. In patients with histologically confirmed grade 3 cervical intraepithelial neoplasia, pretreatment cytologic diagnosis and subsequent histopathologic diagnosis corresponded in 73% of cases. In 91% of all patients the diathermy loop excision was sufficient for complete treatment. Cervical morphologic findings after treatment allowed adequate cytologic follow-up. There was no evidence that diathermy loop excision influenced fertility or pregnancy outcome. CONCLUSION: Diathermy loop excision is a reliable, well-tolerated, inexpensive, and efficient technique for the management of cervical intraepithelial neoplasia. This outpatient procedure is especially recommended in younger patients, because diathermy loop excision preserves the function of the cervix.

Computerized bipolar diathermy with scissors and forceps in cutaneous surgery.

BACKGROUND: Bipolar diathermy coagulates tissue as effectively as monopolar with less lateral tissue injury and no risk of interference with cardiac pacemakers or joint prostheses. OBJECTIVE: To test a novel computerized bipolar diathermy machine for combined cutting and coagulation in dermatologic surgery. METHODS: A divided cable was used to deliver current from a computerized bipolar diathermy unit to both scissors and forceps. The bipolar diathermy unit senses tissue contact with the instruments and starts automatically; a built-in microcomputer measures tissue impedance and automatically terminates the current when tissue coagulation is achieved. RESULTS: The equipment has been used successfully in more than 200 patients undergoing dermatologic surgery. The advantages were a reduced operating time and a more secure hemostasis. The microprocessor controlled bipolar diathermy unit minimized any tissue adherence to the instruments during use. CONCLUSION: We recommend the use of insulated scissors and computerized bipolar diathermy for safe and efficacious coagulation and cutting in dermatologic surgery.

Short wave diathermy for small spontaneous pneumothorax.

BACKGROUND: The treatment of small spontaneous pneumothorax can involve observation, tube thoracostomy, and surgery. This study evaluated the use of short wave diathermy as a method of accelerating the resolution of small pneumothoraces. METHODS: Twenty two patients with pneumothoraces of less than 30% by volume were randomly allocated to receive short wave diathermy for 25 minutes each day (n = 11) or observation with bed rest (n = 11). Chest radiographs were taken until the pneumothoraces resolved. RESULTS: There were no significant differences in the clinical characteristics between the two groups of patients. However, the mean (SD) rate of absorption was significantly higher with short wave diathermy than with observation (3.44 (0.94)% versus 1.57 (0.53)%, difference = 1.87, 95% confidence interval (CI) 1.19 to 2.55, p < 0.001). The time to complete reexpansion was shorter with short wave diathermy than with observation (6.86 (3.51) days versus 11.64 (3.61) days, difference = -4.78 days, 95% CI -7.95 to -1.61, p < 0.005). No evidence of damage resulting from short wave diathermy was found. CONCLUSIONS: Although further study is necessary, these results indicate that short wave diathermy may be an alternative treatment for patients with small spontaneous pneumothoraces.
