Immediate outcome of twin–twin transfusion syndrome following selective laser photocoagulation of communicating vessels at the NSW Fetal Therapy Centre

The Australian and New Zealand Journal of Obstetrics and Gynaecology — Wed, 17 Mar 2010 00:00:00 +0100

Conclusions: Selective laser photocoagulation of communicating vessels remains the treatment of choice for TTTS. Referrals to the NSW FTC have increased from five cases in the last half of 2003, to 18 cases in the first half of 2008. Local outcome figures at least equal any in the published international literature and support a continued policy of centralised care in Australia. A two-year follow-up study on neonatal outcome for survivors is underway. (Source: The Australian and New Zealand Journal of Obstetrics and Gynaecology)

The 3S technique: Another minimally invasive technique in the treatment of saphenous varicose veins

Journal of the American Academy of Dermatology — Tue, 16 Mar 2010 14:28:13 +0100

To the Editor: I read with interest the article by Nijsten et al in the January 2009 issue of the Journal that describes three minimally invasive techniques in the treatment of saphenous varicose veins: foam sclerotherapy, endovenous laser therapy, and radiofrequency ablation. Another procedure—the 3S saphenectomy (the 3S technique)—should be added to theses techniques. The 3S technique associates the surgical sectioning and sclerotherapy of saphenous veins under local anesthesia. It has been developed in France mainly by Vin et al. Many angiophlebologists learned this technique during the educational program of the European School of Phlebology in Paris. It is useful in the following instances: (1) when surgery is not recommended because of an advanced age and/or in case of a leg ul...

Lymphatic malformations: A proposed management algorithm

International Journal of Pediatric Otorhinolaryngology — Tue, 09 Mar 2010 14:30:50 +0100

Conclusion: Historically surgical excision has been the management option of choice for lymphatic malformations. However due to the morbidity and high complication rate associated this is increasingly being questioned. Recent advances in sclerotherapy e.g. OK-432 injection have also shown significant promise. Based on experience in managing these lesions as well as current literature the authors of this paper have developed an algorithm for the management of cervicofacial lymphatic malformations.

Low-Level Laser Treatment

The Journal of Hand Surgery — Mon, 01 Mar 2010 00:00:00 +0100

A 55-year-old, right-handed man presents with numbness and pain in his right thumb, index, and long fingers that wakes him from sleep. Electrodiagnostic studies are consistent with carpal tunnel syndrome (CTS) with a motor latency greater than 7 ms. He received transient relief from a steroid injection. The wrist brace that prevented night symptoms for years is no longer helpful. The patient prefers to avoid surgery and requests low-level laser therapy (LLLT), which he read about on the Internet.

LANCET — Fri, 26 Feb 2010 00:00:00 +0100

We thank Arianne Verhagen and Jasper Schellingerhout for their comments and for bringing a typographical error in figure 4 to our attention. A correction of the data for the laser group in Chow et al (2004) from 27 to 21 mm reduces the combined mean difference by 0·45 mm. However, Verhagen and Schellingerhout's claim that pain improvement in this trial was not significant is inconsistent with the published trial report which stated that p=0·039. Moreover, data on significance in single trials are never used in meta-analytical calculations. (Source: LANCET)

Ho:YAG-laser: treatment of vesicourethral strictures after radical prostatectomy

World Journal of Urology — Thu, 25 Feb 2010 06:50:57 +0100

Conclusion Ho:YAG laser endourethrotomy tends to be a safe and at least minimally invasive therapeutic modality for the treatment of bladder neck contractures after radical prostatectomy. No cohort study that evaluates the use of laser for this modality is available in literature. Due to the lack of comparable randomized multicentre trials, the indications for a laser-related endoscopic treatment option has to be defined based on the operators expertise and the patient’s individual situation.

In vitro analysis of human tooth pulp chamber temperature after low-intensity laser therapy at different power outputs

Lasers in Medical Science — Thu, 11 Feb 2010 11:48:56 +0100

Abstract In vitro studies have provided conflicting evidence of temperature changes in the tooth pulp chamber after low-level laser irradiation of the tooth surface. The present study was an in vitro evaluation of temperature increases in the human tooth pulp chamber after diode laser irradiation (GaAlAs, λ = 808 nm) using different power densities. Twelve human teeth (three incisors, three canines, three premolars and three molars) were sectioned in the cervical third of the root and enlarged for the introduction of a thermocouple into the pulp chamber. The teeth were irradiated with 417 mW, 207 mW and 78 mW power outputs for 30 s on the vestibular surface approximately 2 mm from the cervical line of the crown. The highest average increas...

Endovenous laser therapy - application studies and latest investigations

Journal of Biophotonics — Thu, 11 Feb 2010 00:00:00 +0100

Endovenous laser therapy (ELT) was introduced in clinical practice as a therapy for incompetent veins about ten years ago. One characteristic of ELT is the broad spectrum of different treatment protocols by means of a variety of laser systems as well as manifold application forms and dosimetry concepts are under investigations. Clinical results with effective, relatively pain-free occlusion of incompetent varicosis veins have been observed, as well as undesired side effects such as ecchymosis, phlebitis and recanalization. In recent years systematic experimental investigations and the analysis of clinical results have increased the understanding of the interrelation between the clinical and physical aspects, followed to a continuous optimization of ELT. The use of IR wavelengths and radial...

Comparative effects of wavelengths of low-power laser in regeneration of sciatic nerve in rats following crushing lesion

Lasers in Medical Science — Fri, 05 Feb 2010 07:02:02 +0100

Abstract Peripheral nerves are structures that, when damaged, can result in significant motor and sensory disabilities. Several studies have used therapeutic resources with the aim of promoting early nerve regeneration, such as the use of low-power laser. However, this laser therapy does not represent a consensus regarding the methodology, thus yielding controversial conclusions. The objective of our study was to investigate, by functional evaluation, the comparative effects of low-power laser (660 nm and 830 nm) on sciatic nerve regeneration following crushing injuries. Twenty-seven Wistar rats subjected to sciatic nerve injury were divided into three groups: group sham, consisting of rats undergoing simulated irradiation; a group consisting of rats subjected to...

Laser Treatment for Ethnic Skin

Facial Plastic Surgery Clinics of North America — Mon, 01 Feb 2010 00:00:00 +0100

With the growth of new technology and products over the last 10 years, there has been an increased ability to improve a patient's appearance with procedures that can be performed in an office setting, including laser procedures. Demand for these procedures has grown among all ethnic groups. Patients with ethnic skin can have varying response to lasers. This factor should be considered when planning their treatment. After laser treatment, Patients with ethnic skin are at greater risk for laser energy absorption by melanin, postinflammatory hyperpigmentation, and loss of pigment due to laser effects on melanin production leading to hypopigmentation. Therefore, any laser therapy should be planned carefully, especially in the treatment of patients with darker skin types. (Source: Facial Plasti...

Paradoxical Hypertrichosis After Laser Therapy: A Review

Dermatologic Surgery — Tue, 19 Jan 2010 00:00:00 +0100

Laser hair removal is a safe and effective procedure for the treatment of unwanted body hair but is not exempt from side effects. A rare but significant adverse effect with this treatment modality is paradoxical hypertrichosis. To evaluate the potential etiologies, risk factors, related laser types, and treatment options for the development of excess hair after laser therapy. An analysis of previously published case studies and review articles along with our own experience was used to gather information regarding this phenomenon. Paradoxical hypertrichosis has a low incidence, ranging from 0.6% to 10%, and most commonly occurs on the face and neck. All laser and light sources have the potential to cause hair induction, especially in individuals with darker skin types (III[ndash]VI); with d...

The Evolution of Transcranial Laser Therapy for Acute Ischemic Stroke, Including a Pooled Analysis of NEST-1 and NEST-2

Current Cardiology Reports — Mon, 18 Jan 2010 18:25:12 +0100

Abstract Intravenous tissue plasminogen activator is the only proven therapy for acute ischemic stroke. Not enough patients are eligible for treatment and additional new therapies are needed. Recently, laser technology has been applied to acute ischemic stroke. This noninvasive technique uses near-infrared wavelengths applied to the scalp within 24 h of symptom onset. The mechanism is incompletely understood but may involve increased mitochondrial adenosine triphosphate production. Animal models demonstrated safety and efficacy warranting randomized controlled trials in humans. NEST-1 (phase 2) and NEST-2 (phase 3) confirmed the safety of transcranial laser therapy, although efficacy was not found in NEST-2. Pooled analysis of NEST-1 and NEST-2 revealed a significantl...

Review paper Foam sclerotherapy, radiofrequency ablation, endovenous laser treatment and ambulatory phlebectomy – advances in the treatment of varicose veins

Articles of Advances in Dermatology and Allergology - TERMEDIA publishing house — Mon, 04 Jan 2010 11:40:58 +0100

Approximately 20% of the general population suffers from symptomatic varicose veins. Many of the risk factors, for example standing or sitting work, habitual constipation or widely used oral contraception, are associated with the lifestyle of developed countries. This qualifies varicosity as a social disease. In this article, aetiology, pathomechanism and standardized international classification are presented. Modern management of varicose veins, such as foam sclerotherapy that has developed from liquid sclerotherapy, intravenous laser therapy, radiofrequency ablation and ambulatory phlebectomy, are also discussed. These procedures, as well as their advantages and disadvantages, are described. The new varicose vein treatment methods are considered to be safe and effective when properly ch...

What's the best treatment for pyogenic granuloma?

The Journal of Family Practice — Fri, 01 Jan 2010 00:00:00 +0100

Authors: Gilmore A, Kelsberg G, Safranek S It's difficult to say which treatment for pyogenic granuloma is best, since most studies don't compare treatments directly. Pros and cons vary. Simple surgical excision is associated with a low risk of recurrence, but often leaves a visible scar. Curettage or shave excision, with cautery, is more likely to succeed in 1 session than cryotherapy; both may leave a smaller scar than surgery. Laser therapy, which may require multiple sessions, and sclerotherapy may be least likely to cause visible scarring. Untreated pyogenic granulomas regress spontaneously within 6 to 18 months with some risk of scarring. PMID: 20074501 [PubMed - in process] (Source: The Journal of Family Practice)

Effect of low-level laser therapy (GaAs 904 nm) in skeletal muscle fatigue and biochemical markers of muscle damage in rats

European Journal of Applied Physiology — Fri, 18 Dec 2009 16:38:25 +0100

Abstract We wanted to test if pre-exercise muscle irradiation with 904 nm laser affects the development of fatigue, blood lactate levels and creatine kinase (CK) activity in a rat model with tetanic contractions. Thirty male Wistar rats were divided into five groups receiving either one of four different laser doses (0.1, 0.3, 1.0 and 3.0 J) or a no-treatment control group. Laser irradiation was performed immediately before the first contraction for treated groups. Electrical stimulation was used to induce six tetanic tibial anterior muscle contractions with 10 min intervals between them. Contractions were stopped when the muscle force fell to 50% of the peak value for each contraction; blood samples were taken before the first and immediately after the sixt...

[Articles] Efficacy of low-level laser therapy in the management of neck pain: a systematic review and meta-analysis of randomised placebo or active-treatment controlled trials

LANCET — Fri, 04 Dec 2009 00:00:00 +0100

Neck pain is a common and costly condition for which pharmacological management has limited evidence of efficacy and side-effects. Low-level laser therapy (LLLT) is a relatively uncommon, non-invasive treatment for neck pain, in which non-thermal laser irradiation is applied to sites of pain. We did a systematic review and meta-analysis of randomised controlled trials to assess the efficacy of LLLT in neck pain. (Source: LANCET)

Lack of awareness amongst community patients with diabetes and diabetic retinopathy: the Singapore Malay eye study.

Annals of the Academy of Medicine, Singapore — Tue, 01 Dec 2009 00:00:00 +0100

CONCLUSION: In a sample of Malays with diabetes, high proportions were unaware of their disease. Unawareness was associated with poorer control of diabetic retinopathy risk factors. Only half of persons who were unaware that they had vision-threatening diabetic retinopathy had received laser treatment. These data highlight room for improvement in diabetic retinopathy prevention through better patient education and screening.

Monochorionic Twin Pregnancy and the Following Problems.

Zeitschrift fur Geburtshilfe und Neonatologie — Tue, 01 Dec 2009 00:00:00 +0100

Authors: Bahlmann F Monochorionic twin pregnancies have an increased risk of intrauterine and postnatal complications because of the present placental vascular anastomoses. The main problems are the development of twin-to-twin transfusion syndrome, selective intrauterine growth restriction, monoamniotic twins and single intrauterine death on the one hand and congenital abnormalities like twin reversed-arterial perfusion and conjoined twins on the other hand. Fetoscopic laser therapy with selective coagulation of placental intertwin anastomoses is the best option in the treatment of twin-to-twin transfusion syndrome. The risk of preterm delivery, cerebral injury and abnormalities of long-term neurodevelopmental outcome are increased. Perinatal management of monochorionic twin pregnancie...

Sporotrichosis and Dematiaceous Fungal Skin Infections.

Nippon Ishinkin Gakk... — Mon, 30 Nov 2009 04:02:03 +0100

Authors: Kusuhara M Sporotrichosis is a chronic infectious granuloma of skin. The detection of fungal elements in pathological examination and the isolation of Sporothrix schenckii from the lesion are requisite for diagnosis. The sporotrichin test is useful as an auxiliary examination, but a false-negative reaction might occur in some cases. Oral potassium iodide is first choice of treatment, because of its modest cost and usefulness, although gastrointestinal disorder is a frequent side effect. Itraconazole should be the second selection, and then terbinafine. Local thermotherapy is also effective as an additional therapy. Dematiaceous fungal skin infections are divided into two groups by their parasitic form, chromoblastomycosis and phaeohyphomycosis. Chromoblastomycosis is also call...

Intermediate-differentiated invasive (pT1 G2) penile cancer-oncological outcome and follow-up.

Urologic Oncology — Thu, 26 Nov 2009 00:00:00 +0100

CONCLUSIONS: For patients with T1 G2 penile cancer, organ preserving therapy appears to be a suitable treatment option. In our series, nearly one third of patients developed inguinal lymph node metastases, which highlights the potential benefit of surgical staging. Larger prospective multicenter studies are needed to define the best treatment strategy for intermediate-differentiated invasive penile cancer.

Fluorescence-guided laser therapy for penile carcinoma and precancerous lesions: Long-term follow-up.

Urologic Oncology — Thu, 26 Nov 2009 00:00:00 +0100

CONCLUSIONS: Local recurrence rate of laser therapy can be reduced by fluorescence guidance without impairing cosmetic or functional results. The necessary equipment is available in many centers that perform PDD for urothelial bladder cancer. PDD, therefore, can be considered to be cost-effective and easy to perform. Prospective multi-center studies to directly compare recurrence rates between white light and fluorescence-guided laser therapy for penile carcinoma are required.

Radiotherapy or CO2 laser surgery as treatment of T1a glottic carcinoma?

European Archives of Oto-Rhino-Laryngology — Sat, 07 Nov 2009 19:18:03 +0100

In conclusion, the relative risk for a laryngectomy when a tumour recurs is 12.7 times higher in patients primarily treated with irradiation for T1a laryngeal carcinoma, compared with patients treated with laser surgery. Regarding the treatment costs, treatment impact on patients and organ preservation, we consider laser therapy to be the better treatment option for patients with T1a glottic cancer as no difference in survival could be observed.

Low-level laser therapy with pulsed infrared laser accelerates third-degree burn healing process in rats.

J Rehabil Res Dev — Wed, 04 Nov 2009 19:34:03 +0100

This study investigated the influence of pulsed low-level laser therapy (LLLT) on the healing of a third-degree burn in a rat model. Two third-degree burns (distal and proximal) were made in the skin of 74 rats. Rats were divided into four groups. In group 1, the distal burn received LLLT with laser switched off; in groups 2 and 3, distal burns were treated with a 3,000 Hz-pulsed infrared diode laser with 2.3 and 11.7 J/cm(2) energy densities, respectively. In group 4, the distal burns were treated topically with 0.2% nitrofurazone. The proximal burn of all groups was considered a control burn. We assessed the response to treatment both microbiologically and macroscopically. The chi-square test showed that the incidence of Staphylococcus epidermidis, Lactobacillus, and diphtheria decreased...

Sexually transmitted papillomavirus infections: epidemiology pathogenesis, clinic, morphology, important differential diagnostic aspects, current diagnostic and treatment options

Anais Brasileiros de Dermatologia — Fri, 23 Oct 2009 12:59:34 +0100

The family of human papilloma viruses (HPV) comprises more than 100 genotypes. Approximately 30 of the genotypes are responsible for infections in the human anogenital area. A precisely defined algorithm with the goal of diagnosing and removing HPV for a prolonged or indefinite length of time, as well as to protect the patient from any malignant ransformation, does not currently exist. The identification of HPV strains by PCR or DNA hybridization in lesional tissue provides higher security for the patients. In high-risk patients additional colposcopy, rectoscopy, and rethroscopy/cystoscopy increase the probability of proper diagnosis and the application of a reliable therapeutic strategy. Removal of lesions by means of invasive methods, such as electrodessication, cryosurgery, and/or laser...

Management of acne vulgaris: an evidence-based update

Clinical And Experimental Dermatology — Thu, 22 Oct 2009 23:00:00 +0100

This review summarizes clinically important findings from 3 systematic reviews, 1 updated guideline and a selection from the 62 randomized controlled trials (RCTs) published between February 2007 and January 2009 on the topic of acne vulgaris. Low glycaemic-load diets might reduce acne severity but this remains unproven. Written patient information leaflets have not been surpassed by other communication methods. New combination topical treatments have not shown convincing advantages over current combination products such as clindamycin/benzoyl peroxide.

Conclusions The initial stage seems to predict outcome. Carbon dioxide laser therapy provides good results primarily in stages I and IIA lymphatic malformations. In advanced lymphatic malformations (stages IIB, III, and IV), an interdisciplinary approach is necessary, because complete surgical excision is often impossible owing to the diffuse growth behavior, and therefore recurrence and persistence are common.

Transcranial Near Infrared Laser Treatment (NILT) Increases Cortical Adenosine-5'-triphosphate (ATP) Content Following Embolic Strokes in Rabbits.

Brain Research — Wed, 14 Oct 2009 23:00:00 +0100

Authors: Lapchak PA, De Taboada L Transcranial near infrared laser therapy (NILT) improves behavioral outcome following embolic strokes in embolized rabbits and clinical rating scores in acute ischemic stroke(AIS) patients; however, the cellular mechanism(s) involved in NILT neuroprotection have not been elucidated. It has been proposed that mitochondrial energy production may underlie a response to NILT, but this has not been demonstrated using an in vivo embolic stroke model. Thus, we evaluated the effect of NILT on cortical ATP content using the rabbit small clot embolic stroke model (RSCEM), the model originally used to demonstrate NILT efficacy and initiate the NEST-1 clinical trial. Five minutes following embolization, rabbits were exposed to 2 minutes of NILT using an 808 nm las...

Interstitial Laser Therapy of Breast Fibroadenomas With 6 and 8 Year Follow-Up

The Breast Journal — Sun, 11 Oct 2009 23:00:00 +0100

Abstract: Fibroadenomas are non-cancerous breast tumors commonly seen in teenagers but also found in women at the time of first mammogram. They have distinct physical findings and imaging features but the definitive diagnosis is made by ultrasound or stereotactic guided needle biopsy. Treatment options are observation or surgical removal. Recently, removal by ultrasound-guided technique has been reported. Alternatively, the tumor may be ablated within the breast by cold (cryotherapy) or by heat (laser, radiofrequency, focused ultrasound and microwave). In this paper the laser treatment in two patients, one with bilateral fibroadenomas, with 6 and 8 year follow-up is presented. (Source: The Breast Journal)

Issues Involving the Management of the Visually Impaired Patient.

American Family Physician — Wed, 30 Sep 2009 23:00:00 +0100

Authors: Pandit RL, Pandit JC Blindness or low vision affects more than 3 million Americans 40 years and older, and this number is projected to reach 5.5 million by 2020. In addition to treating a patient's vision loss and comorbid medical issues, physicians must be aware of the physical limitations and social issues associated with vision loss to optimize health and independent living for the visually impaired patient. In the United States, the four most prevalent etiologies of vision loss in persons 40 years and older are age-related macular degeneration, cataracts, glaucoma, and diabetic retinopathy. Exudative macular degeneration is treated with laser therapy, and progression of nonexudative macular degeneration in its advanced stages may be slowed with high-dose antioxidant and zi...

Current studies on myofascial pain syndrome

Current Pain and Headache Reports — Fri, 18 Sep 2009 06:23:48 +0100

Abstract Recent studies have clarified the nature of myofascial trigger points (MTrPs). In an MTrP region, multiple hyperirritable loci can be found. The sensory components of the MTrP locus are sensitized nociceptors that are responsible for pain, referred pain, and local twitch responses. The motor components are dysfunctional endplates that are responsible for taut band formation as a result of excessive acetylcholine (ACh) leakage. The concentrations of pain- and inflammation-related substances are increased in the MTrP region. It has been hypothesized that excessive ACh release, sarcomere shortening, and release of sensitizing substances are three essential features that relate to one another in a positive feedback cycle. This MTrP circuit is the connection among spin...

Excimer Laser Assisted Angioplasty in Hemodialysis Access Intervention

Seminars In Dialysis — Tue, 08 Sep 2009 23:00:00 +0100

A case is described in which an excimer laser is used to assist angioplasty of a severe central venous lesion that is refractory to conventional techniques. Modern laser technology uses the ultraviolet (UV) spectral region to generate nanosecond pulses of energy. This results in photoablation, which is the process by which energy photons cause molecular bond disruption, while minimizing thermal damage to the surrounding vascular tissues. Further investigation of excimer laser assisted angioplasty in the setting of hemodialysis access intervention is needed to rigorously define its potential role. In occlusive disease where no conventional alternative is available, however, laser therapy is a viable option. (Source: Seminars In Dialysis)

In vivo study of age-related changes in the optical properties of the skin

Lasers in Medical Science — Thu, 03 Sep 2009 06:32:25 +0100

Abstract The optical properties of the skin (absorption coefficient, scattering coefficient, refractive index) may serve to characterize the skin and are important for correct light dosimetry in many optical diagnostic procedures and laser treatments especially photodynamic therapy and laser therapy. We determined in vivo the optical properties of tissues near the wrist, elbow and knee in subjects of different ages using diffuse reflectance spectroscopy, having in view the establishment of laser system types for the laser treatment of posttraumatic lesions in subjects of different ages. Diffuse reflection of light from biological tissue is due to the variation in refractive index of tissular and cellular components and the surrounding medium and depends on the wavelength o...

Conclusions: The method of photodynamic diagnostics does not replace the necessity of performing histopathological examinations, which still are of basic importance, but the places of affected skin specimen sampling may be determined by a non-invasive method. Moreover, the method of so-called “optic biopsy”, supplementing diagnostic investigations by determining the precise boundary line of the change, enables first of all total tumour excision, obtaining simultaneously an optimal cosmetic effect, particularly in the case of superficial changes.
