Laser therapy as a treatment modality for genitourinary syndrome of menopause: a critical appraisal of evidence.

Interest in laser therapy as a nonhormonal option for the treatment of genitourinary syndrome of menopause (GSM) has increased. We conducted a systematic review of the use of laser therapy for the relief of GSM symptoms. Six electronic databases were searched and conference abstracts were searched manually from the introduction of laser therapy to the present date. The keywords used were: "genitourinary syndrome", "vulvovaginal atrophy", "postmenopausal symptoms", "laser therapy" and "fractional laser treatment". Of the 165 articles identified in the search, none was a randomized controlled trial. As a result, we included three observational studies without a control group and one case-control study that met our inclusion criteria. The total number of women included in the four studies was 220. The collated data suggest that laser therapy may be valuable as a nonhormonal therapeutic modality in the management of GSM. Higher quality of evidence from randomized controlled trials is required to establish the efficacy of laser treatment in the management of GSM.

Paediatric perioperative cardiac arrest and its mortality: database of a 60-month period from a tertiary care paediatric centre.

BACKGROUND AND OBJECTIVE: The analysis of perioperative cardiac arrest and mortality remains a potentially valuable method to improve clinical outcome. This survey evaluated the incidence and causes of perioperative cardiac arrests and mortality in a paediatric surgical population over 5 years. METHODS: All cardiac arrests that occurred between April 2003 and March 2008, during administration of anaesthesia at the paediatric centre of our institute, were recorded from an anaesthesia database and postsurgical ICU census register. All surgery performed under anaesthesia was included whether emergency or elective. All surgical procedures were covered except eye surgery, cardiac surgery and the procedures performed at remote locations. Data collected included patient characteristics, surgical procedures, preoperative physical status and anaesthesia-provider information, immediate cause of cardiac arrest, antecedent events, management and outcome. All cardiac arrests were grouped according to the cause of arrest into one of four groups: totally anaesthesia related, partially anaesthesia related, surgery related or child condition related. RESULTS: There were a total of 27 cardiac arrests out of 12 158 procedures. Major risk factors for cardiac arrests were children under 1 year of age (P < 0.05), ASA physical status (ASA-PS) III or more (P < 0.001) and emergency surgery (P < 0.01). There were nine cardiac arrests attributed to anaesthesia, three totally and six partially related to anaesthesia. The main causes of anaesthesia-related cardiac arrest were respiratory events (56%), followed by cardiac events (33%). Anaesthesia-related mortality was 1.2/10 000 anaesthetics in patients with ASA-PS I-II and 7.7/10 000 anaesthetics in patients with ASA-PS III-V with a survival rate of 56%. CONCLUSION: Major risk factors for cardiac arrests were age under 1 year, poor physical status and emergency surgery. Respiratory and cardiovascular-related events accounted for most of all anaesthesia-related cardiac arrests. High ASA-PS was the leading cause of perioperative mortality.

Urethral pain syndrome and its management.

UNLABELLED: Urethral pain syndrome is occurrence of persistent or recurrent episodic urethral pain usually on voiding with daytime frequency and nocturia, in the absence of proven infection or other obvious pathology. This is a condition of uncertain etiology. The objective of this article is to review etiology, diagnosis, and management of urethral pain syndrome. Since there is paucity of information on randomized trials, search of published literature has been made using keywords such as "urethral pain syndrome", "painful bladder syndrome", "urethral stenosis", and "lower urinary tract symptoms". Urethral pain syndrome is a disease of ambiguous etiology. Diagnosis is mainly based upon symptoms, and investigations are aimed to exclude other conditions affecting lower urinary tract. Various modalities of treatment including antibiotics, alpha-blockers, acupuncture, and laser therapy have been proved successful. Psychological support is very important in this group of women. Management requires multidisciplinary approach, and treatment at its best is by trial and error. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this article, the reader should be able to explain that the urethral pain syndrome (UPS) has specific signs and symptoms without specific responses to a variety of treatment options and recall that treatment may require a multidisciplinary approach and a lot of sensitivity by the physician.
