Recently Published Article – “Management of an Extensive Vascular Lesion on the Lip by Photocoagulation with High-Intensity Diode Laser”

Journal: The Open Dentistry Journal

Author(s): Luciane H. Azevedo, Dante Migliari




Extensive vascular malformations (VM) pose difficulties for an effective management.


This article describes a very satisfactory result, both functional and aesthetic, following a management by the technique of photocoagulation using diode laser in an extensive VM lesion involving the lower lip and left buccal mucosa in a 25 year old male.

Case report:

The patient reported that the lesion had been present since birth. The whole treatment, carried out under local anesthesia, spread over 6 months since as many as 4 sessions of laser, with a 1.5-month interval in each, were required. The resting period between sessions played an important part in treatment by allowing a time for the recovery of the patient and the shrinking of the lesion.


The patient had no complications during the laser sessions, and his postoperative period was uneventful. No recurrence has been seen after a 2.5-year follow-up.

World Brain Tumor Day 2017!


World Brain Tumor Day is observed annually on 8th of June. Observance of World Brain Tumor Day raises public awareness and educates people about this little-known type of cancer. It also draws public attention to people suffering from brain tumors. Brain tumor is a condition that occurs when the cells in the brain multiply in an abnormal way or a way that cannot be controlled. The tumor can be malignant meaning it is cancerous or it can be non-cancerous (benign).

Bentham Open publishes very important research studies on Brain Tumor in the following journal:

Recently Published Article – “Why Do Healthy Men Experience Morning Erections?”

Journal: The Open Psychology Journal

Author(s): Gahyun Youn



People begin the sleep cycle with a period of non-rapid eye movement (NREM) sleep, followed by a very short period of rapid eye movement (REM) sleep. During a normal night of sleep, humans usually experience about four or five periods of REM sleep. Penile erections have generally been considered to be an epiphenomenon of REM sleep-related physiological changes for healthy males. Thus, men are very likely to awaken in the morning with a REM sleep-related erection, which is also known as nocturnal penile tumescence (NPT). Men who are physically under great strain or serious psychological stress may find it difficult to maintain a psychogenic erection. The best time for them to have sex would be during sleep time, such as when they are experiencing REM sleep-related erections. It is reasonable to assume that the NPT phenomena might have evolved as a tool for having sex, in the context of both procreation and recreation.

Recently Published Article – “Electrocardiographic Changes After Suicidal Digoxin Intoxication in a Healthy Woman”

Journal: The Open Cardiovascular Medicine Journal

Author(s): Natalia Lorenzo Muñoz, Amparo Benedicto Buendía, Fernando Alfonso Manterola




Suicidal digoxin intoxication is a rare clinical entity. Clinical suspicious remains of paramount importance as adequate interpretation of the electrocardiographic changes enable to readily initiate treatment.


We describe a case of suicidal attempt after massive digoxin intake that was satisfactory managed with conservative management strategy that involved a close clinical surveillance of the evolving electrocardiographic changes and digoxin serum levels.

World Environment Day 2017!


World Environment Day is held each year on June 5. This day is observed to stimulate worldwide awareness of the environment.

Bentham Open Publishers is in the forefront in creating awareness about this through the research in the journal:

Recently Published Article – “Seabirds At-Sea Surveys: The Line-Transect Method Outperforms the Point-Transect Alternative”

Journal: The Open Ornithology Journal

Author(s): François Bolduc, David A. Fifield




Knowledge of seasonal distribution and abundance of species is paramount in identifying key areas. Field data collection and analysis must provide best information concerning seabirds at-sea to optimize conservation efforts.


We tested whether modeling of detection probabilities, and density estimates with their coefficients of variation obtained from the point-transect method provided more robust and precise results than the more commonly used line-transect method. We subdivided our data by species groups (alcids, and aerialist species), and into two behavior categories (flying vs. swimming). We also computed density estimates from the strip-transect and point count methods, to relate differences between transect methods to their counterparts that do not consider a decreasing probability of detection with distance from the observer. We used data collected in the Gulf of St. Lawrence between 2009 and 2010 when observers simultaneously conducted line- and point-transect sampling.


Models of detection probability using the line-transect method had a good fit to the observed data, whereas detection probability histograms of point-transect analyses suggested substantial evasive movements within the 0-50 m interval. This resulted in point-transect detection probability models displaying poor goodness of fit. Line transects yielded density estimates 1.2-2.6 times higher than those obtained using the point-transect method. Differences in percent coefficients of variation between line-transect and point-transect density estimates ranged between 0.2 and 5.9.


Using 300 m wide line-transects provided the best results, while other methods could lead to biased conclusions regarding species density in the local landscape and the relative composition of seabird communities among species and behavior groups.
