Hemorrhoids is one of the most common proctological diseases of the anal canal. In the guidelines presented in 2018 in „Diseases of the Colon & Rectum”, the American Society of Colon and Rectal Surgeons (ASCRS) hasn’t specified laser techniques as a method of treatment. The first attempts of laser trail in hemorrhoidal treatment were made at the end of the 70s by using laser CO2 instead of scalpel. Nowadays one of the newest devices is Leonardo laser which emits fan-shaped movement of 1470 nm length. It enabled the development of laser hemorrhoidoplasty technique (LHP). The advantage of this procedure is decrease of hemorrhoidal plexus by obliteration of hemorrhoidal vessels leading to their fibrosis. It reclaims almost anatomical architecture of anal canal without a necessity to excise the extended hemorrhoids. Development of the connective tissue fibers guarantees adequate adhesion of mucosa to the underlying tissue which prevents the recurrence of the disease, especially the ones connected with prolapsing of hemorrhoids. The article contains a description of the method recommended by the manufacturer of Leonardo laser with the autors’ modifications developed on the basis of their own experience.

This is a study of 61 cases of turbinoplasty done in 3 hospitals of Bangladesh from August2007 to July 2009 (2 years). This study compares turbinoplasty by laser with that of non-lasertechniques. 60.65% of patients were operated by laser and 39.34% of patients were operatedby non-laser techniques. Majority of the patients were from 21- 40 years of age, (62.16% inlaser group and 54.16% in non-laser group). Male & Female patients ratio was 3:1 in bothgroups. 100% of the patients were presented with nasal obstruction. 98.36% with nasaldischarge, 95.08% with headache and 75.40% with frequent sneezing (p<0.01). Most patientswere operated under local anesthesia in both groups (78.38% and 58.33% respectably).Follow up was satisfactory up to 3 months (Laser group 81.08 % and non-laser group 70.83%). Most of the patient were all symptoms free (86.48 % in laser group and 79.16 % in nonlasergroup). Only 8 patients (21.62%) present with crusting in laser group in respect to 22patients (91.66%) in non-laser group with no incidence of severe post–operative nasal bleedingin laser group. 34 patients (91.89%) of Laser group and 13 patients (35.13%) of non-lasergroup were treated as day care surgery.Most of the cases (70.27%) were operated by diode laser. Recurrences of symptoms werenegligible in laser group (2.70%).Key Words: Laser; Turbinoplasty.DOI: 10.3329/bjo.v16i1.5775Bangladesh J Otorhinolaryngol 2010; 16(1): 9-14

Soft Tissue Surgery

Referral to an oral surgeon for soft-tissue surgery before, during or after orthodontic treatment is not uncommon. This process may delay treatment and could potentially increase the risk of complications. In addition, seeing multiple specialties in different environments may demotivate paediatric or anxious patients from pursuing orthodontic treatment and could also adversely affect patient compliance and satisfaction. The development of laser technology provides a safe and effective alternative, allowing the orthodontic clinician to perform soft-tissue surgery. To date, there are no laser exposure protocols or UK guidelines regarding the use of laser surgery in orthodontics. This case series reports four clinical cases that demonstrate potential advantages of using a diode laser for the management of soft tissue in the field of orthodontics.

Fish Monitoring

Stereovision and laser techniques allow for getting knowledge about fish, mostly when they are combined with computer vision. This kind of techniques avoid to use traditional procedures such as direct observation, which are impractical or can affect the fish behavior, in task such as aquarium and fish farm management or fishway, like vertical slot fishway, evaluation. This chapter describes in a first stage, the use stereovision join with computer vision to fish monitoring and measure size of fishes. In the second part, using laser technology and computer vision to fish detection, especially in slot fishways. Vertical slot fishways are structures that are placed in rivers to allow fish to avoid obstacles such as dams, hydroelectric plants. Then, it shows a results section and finally authors' conclusions.

III-V semiconductor diode lasers can be used to make accurate measurements of the concentrations of gases. In this paper the field of trace gas detection using III-V semiconductor diode lasers will be reviewed with an emphasis on suitable applications of this technology in pipeline monitoring. III-V semiconductor diode lasers emit light in the near infrared (NIR) with wavelengths ranging from 1 to 2 μm. Many molecules have absorption lines in this spectral range which makes them contenders for detection with diode laser technology. Molecules relevant to the pipeline industry that can be detected using diode laser systems include H2S, C2H4, C2H2, HF, CO2, CO, O2, NH3, HC1, NO, NO2, HCN, H2O and CH4. Diode laser detection systems may be well suited for many pipeline related applications. Portable field-screening detection systems may be possible, such as hand-held systems which can be used to pinpoint leaks for compressor station inspection. Airborne (∼200 km/h) and mobile (∼40 km/h) systems which can be used for pipeline and urban area inspection may also be feasible. Stationary systems can be integrated into pipeline systems to provide real-time remote gas monitoring for Supervisory Control and Data Acquisition (SCADA) systems. Detection sensitivities of parts per million (ppm) or better are achievable for many gases. A single diode laser detector can be designed to detect more than one gas leading to versatile multipurpose systems. As III-V diode laser based gas detection systems exploit the same technologies as the highly successful telecommunications industry they have the potential to be low in cost, reliable, and easy to operate and maintain. We will present an overview of state-of-the-art III-V diode laser detection systems. System performance will be evaluated and the usefulness of these types of detection systems will be demonstrated.
