Survey of Sexual Function and Pornography.

INTRODUCTION: We aimed to explore and describe the pornography habits of young men and women. Given recent upward trends in pornography use and erectile dysfunction, along with a plausible pathophysiology, we hypothesized that pornography use would correlate with sexual dysfunction. MATERIALS AND METHODS: Institutional Review Board approval was obtained. Surveys were distributed to 20-40 year old men and women presenting to a urology clinic. Information was collected on demographics and medical history. Sexual function was evaluated with the International Index of Erectile Function (IIEF) in men and the Female Sexual Function Index in women. Extent of potential addiction to pornography was measured with the pornography craving questionnaire and the obsessive passion scale. Pornography use was measured based on both frequency and duration, and analyzed relative to sexual dysfunction. RESULTS: Men used pornography significantly more frequently than women (81.1% vs. 39%). Computer and cellular phone image viewing were the most popular modalities in both sexes. There was no association between IIEF and craving for, or obsessive passion for, pornography. Preference for pornography with masturbation was found to be significantly associated with erectile dysfunction (p = 0.001). Rates of erectile dysfunction were lowest in those preferring partnered sex without pornography (22.3%) and increased significantly when pornography was preferred over partnered sex (78%). No correlation was found between any variables and female sexual dysfunction. CONCLUSIONS: Pornography and sexual dysfunction are common among young people. No clear relationship exists between extent of addiction to pornography and sexual dysfunction in either gender. However, men who prefer masturbation with pornography to partnered sex have a significantly increased risk of sexual dysfunction. Given sexual dysfunction may be associated with mental health concerns, further evaluation of its causes and impact on military operational readiness are warranted.

Behaviors Associated with Internet Use in Military Medical Students and Residents.

INTRODUCTION: Problematic use of video games, social media, and Internet-related activities may be associated with sleep deprivation and poor work performance. The Internet Addiction Test was given to military medical and nursing students and housestaff to assess problematic Internet use. METHODS: Medical and nursing students at the Uniformed Services University of the Health Sciences and residents from Naval Medical Center San Diego were contacted via email (n = 1,000) and given a survey that included the Internet Addiction Test (IAT) and questions asking about other specific lifestyle variables. Individuals who received an Internet Addiction Score (IAS) ≥50 were identified as likely experiencing harmful effects of Internet addiction (IA). RESULTS: Of 399 surveys submitted, 68 were omitted due to gross incompletion or failing to finish the entirety of the IAT. Of the participants included, 205 (61.1%) were male and 125 (37.9%) were female. The mean age was 28.6 years old (S.D. = 5.1 years). In regards to training status, completed surveys were assessed for 94 medical residents, 221 School of Medicine students, and 16 Graduate School of Nursing students. Our survey showed 5.5% of the participants (n = 18) indicated problems with Internet use that are concerning for IA. CONCLUSIONS: The study results indicated that our population showed problematic Internet use in the lower range of global estimates of IA. Rates of IA further decreased between medical students and residents. Multiple lifestyle variables were significantly associated with IA score and may serve as indicators of a higher score. Interestingly, the use of social media during sleeping hours was most significantly associated with increased IAS. This paper discusses IA among military medical and nursing trainees and how problematic Internet use may affect work performance and force readiness.

A Randomized, Head-to-Head Study of Virtual Reality Exposure Therapy for Posttraumatic Stress Disorder.

Virtual reality exposure therapy (VRET) is one of the few interventions supported by randomized controlled trials for the treatment of combat-related posttraumatic stress disorder (PTSD) in active duty service members. A comparative effectiveness study was conducted to determine if virtual reality technology itself improved outcomes, or if similar results could be achieved with a control exposure therapy (CET) condition. Service members with combat-related PTSD were randomly selected to receive nine weeks of VRET or CET. Assessors, but not therapists, were blinded. PTSD symptom improvement was assessed one week and 3 months after the conclusion of treatment using the clinician-administered PTSD scale (CAPS). A small crossover component was included. Results demonstrated that PTSD symptoms improved with both treatments, but there were no statistically significant differences between groups. Dropout rates were higher in VRET. Of those who received VRET, 13/42 (31%) showed >30% improvement on the CAPS, versus 16/43 (37%) who received CET. Three months after treatment, >30% improvement was seen in 10/33 (30%) of VRET participants and 12/33 (36%) in CET. Participants who crossed over (n = 11) showed no statistically significant improvements in a second round of treatment, regardless of condition. This study supported the utility of exposure therapy for PTSD, but did not support additional benefit by the inclusion of virtual reality.

Responding to Trauma at Sea: A Case Study in Psychological First Aid, Unique Occupational Stressors, and Resiliency Self-Care.

The U.S. Navy deploys Special Psychiatric Rapid Intervention Teams (SPRINT) to sites of military disasters to assist survivors and the command. SPRINT functions primarily as a consultant to help commands effectively respond to the mental health needs of their service members following a traumatic event. Utilizing the principles of psychological first aid, the overall goal of SPRINT is to mitigate long-term mental health dysfunction and facilitate recovery at both the individual and unit level. We present a case study of a SPRINT mission to a deployed U.S. Navy ship in response to a cluster of suicides and subsequent concerns about the well-being of the remaining crew. Throughout this mission, important themes emerged, such as the impact of accumulated operational stressors and the subsequent development of mental health stigma. Also, this case study demonstrates the potential effectiveness of introducing resiliency self-care meditation training to remote environments that lack ready access to mental health resources. From here, SPRINT can provide a model for immediate disaster mental health response that has potential relevancy beyond the military.

Is Internet Pornography Causing Sexual Dysfunctions? A Review with Clinical Reports.

Traditional factors that once explained men's sexual difficulties appear insufficient to account for the sharp rise in erectile dysfunction, delayed ejaculation, decreased sexual satisfaction, and diminished libido during partnered sex in men under 40. This review (1) considers data from multiple domains, e.g., clinical, biological (addiction/urology), psychological (sexual conditioning), sociological; and (2) presents a series of clinical reports, all with the aim of proposing a possible direction for future research of this phenomenon. Alterations to the brain's motivational system are explored as a possible etiology underlying pornography-related sexual dysfunctions. This review also considers evidence that Internet pornography's unique properties (limitless novelty, potential for easy escalation to more extreme material, video format, etc.) may be potent enough to condition sexual arousal to aspects of Internet pornography use that do not readily transition to real-life partners, such that sex with desired partners may not register as meeting expectations and arousal declines. Clinical reports suggest that terminating Internet pornography use is sometimes sufficient to reverse negative effects, underscoring the need for extensive investigation using methodologies that have subjects remove the variable of Internet pornography use. In the interim, a simple diagnostic protocol for assessing patients with porn-induced sexual dysfunction is put forth.

Case Report: Internet Gaming Disorder Associated With Pornography Use.

Internet gaming disorder (IGD) is not currently a recognized diagnosis in the Diagnostic and Statistical Manual for Mental Disorders-5 (DSM-5). However, IGD has been noted to warrant further research for possible future inclusion in the DSM. In many ways, IGD strongly resembles substance and gambling addictions. Such characteristics include tolerance, withdrawal, and social and occupational neglect resulting from increased time invested in video game use and acquisition. The use of similar or closely related media is also seen, which mirrors the natural course of substance and gambling addictions. We present a case of a 22-year-old man who exhibited IGD and problems associated with pornography use. This case report exemplifies the sequelae of IGD. Our paper also reviews the possible mechanisms of behavioral addiction, as well as the status of IGD as a potential subcategory of behavioral addiction. Additional research is needed to determine if IGD co-occurs with problematic use of pornography.

Excessive Video Game Use, Sleep Deprivation, and Poor Work Performance Among U.S. Marines Treated in a Military Mental Health Clinic: A Case Series.

Excessive use of video games may be associated with sleep deprivation, resulting in poor job performance and atypical mood disorders. Three active duty service members in the U.S. Marine Corps were offered mental health evaluation for sleep disturbance and symptoms of blunted affect, low mood, poor concentration, inability to focus, irritability, and drowsiness. All three patients reported insomnia as their primary complaint. When asked about online video games and sleep hygiene practices, all three patients reported playing video games from 30 hours to more than 60 hours per week in addition to maintaining a 40-hour or more workweek. Our patients endorsed sacrificing sleep to maintain their video gaming schedules without insight into the subsequent sleep deprivation. During the initial interviews, they exhibited blunted affects and depressed moods, but appeared to be activated with enthusiasm and joy when discussing their video gaming with the clinical provider. Our article illustrates the importance of asking about online video gaming in patients presenting with sleep disturbances, poor work performance, and depressive symptoms. Because excessive video gaming is becoming more prevalent worldwide, military mental health providers should ask about video gaming when patients report problems with sleep.

Tendon rupture associated with excessive smartphone gaming.

IMPORTANCE: Excessive use of smartphones has been associated with injuries. OBSERVATIONS: A 29-year-old, right hand-dominant man presented with chronic left thumb pain and loss of active motion from playing a Match-3 puzzle video game on his smartphone all day for 6 to 8 weeks. On physical examination, the left extensor pollicis longus tendon was not palpable, and no tendon motion was noted with wrist tenodesis. The thumb metacarpophalangeal range of motion was 10° to 80°, and thumb interphalangeal range of motion was 30° to 70°. The clinical diagnosis was rupture of the left extensor pollicis longus tendon. The patient subsequently underwent an extensor indicis proprius (1 of 2 tendons that extend the index finger) to extensor pollicis longus tendon transfer. During surgery, rupture of the extensor pollicis longus tendon was seen between the metacarpophalangeal and wrist joints. CONCLUSIONS AND RELEVANCE: The potential for video games to reduce pain perception raises clinical and social considerations about excessive use, abuse, and addiction. Future research should consider whether pain reduction is a reason some individuals play video games excessively, manifest addiction, or sustain injuries associated with video gaming.

Internet addiction disorder and problematic use of Google Glass™ in patient treated at a residential substance abuse treatment program.

INTRODUCTION: Internet addiction disorder (IAD) is characterized by the problematic use of online video games, computer use, and mobile handheld devices. While not officially a clinical diagnosis according to the most recent version of the Diagnostic and Statistical Manual of Mental Disorders (DSM), individuals with IAD manifest severe emotional, social, and mental dysfunction in multiple areas of daily activities due to their problematic use of technology and the internet. METHOD: We report a 31year-old man who exhibited problematic use of Google Glass™. The patient has a history of a mood disorder most consistent with a substance induced hypomania overlaying a depressive disorder, anxiety disorder with characteristics of social phobia and obsessive compulsive disorder, and severe alcohol and tobacco use disorders. RESULTS: During his residential treatment program at the Navy's Substance Abuse and Recovery Program (SARP) for alcohol use disorder, it was noted that the patient exhibited significant frustration and irritability related to not being able to use his Google Glass™. The patient exhibited a notable, nearly involuntary movement of the right hand up to his temple area and tapping it with his forefinger. He reported that if he had been prevented from wearing the device while at work, he would become extremely irritable and argumentative. CONCLUSIONS: Over the course of his 35-day residential treatment, the patient noted a reduction in irritability, reduction in motor movements to his temple to turn on the device, and improvements in his short-term memory and clarity of thought processes. He continued to intermittently experience dreams as if looking through the device. To our knowledge, this is the first reported case of IAD involving problematic use of Google Glass™.

Importance of Virtual Reality to Virtual Reality Exposure Therapy, Study Design of a Randomized Trial.

Post Traumatic Stress Disorder (PTSD) can be a debilitating problem in service members who have served in Iraq or Afghanistan. Virtual Reality Exposure Therapy (VRET) is one of the few interventions demonstrated in randomized controlled trials to be effective for PTSD in this population. There are theoretical reasons to expect that Virtual Reality (VR) adds to the effectiveness of exposure therapy, but there is also added expense and difficulty in using VR. Described is a trial comparing outcomes from VRET and a control exposure therapy (CET) protocol in service members with PTSD.

Risk of PTSD in service members who were fired upon by the enemy is higher in those who also returned fire.

An unusual characteristic of the recent wars in Iraq and Afghanistan is that, because of attacks by snipers and improvised explosive devices (IED), many U.S. service members may come under attack without having exchanged fire. It was hypothesized that this would be associated with greater severity of post-traumatic stress disorder (PTSD) symptoms. The severity of self-reported symptoms of PTSD and depression were examined among service members who reported being shot at or attacked by an IED, those who had these experiences but who also shot at the enemy, and those who reported neither experience. Results showed that those with neither exposure reported the lowest symptom severity, but, contrary to expectations, service members who had been attacked but not shot at the enemy had less severe symptoms than those who had exchanged fire. This may support findings from earlier generations of veterans that shooting at or killing the enemy may be a particularly traumatic experience.

Post-traumatic stress disorder symptom severity in service members returning from Iraq and Afghanistan with different types of injuries.

INTRODUCTION: Risk for post-traumatic stress disorder (PTSD) varies in part due to the nature of the traumatic event involved. Both injury and return from combat pose high risk of PTSD symptoms. How different injuries may predispose towards PTSD is less well understood. METHODS: A retrospective record review was conducted from 1402 service members who had returned to Naval Medical Center San Diego from Iraq or Afghanistan and who had completed the PTSD Checklist as part of their post-deployment screening. Rates of PTSD were examined in relation to mechanism of injury. RESULTS: Of those without injury, 8% met Diagnostic and Statistical Manual criteria for PTSD. Thirteen percent of those with a penetrating injury, 29% with blunt trauma, and 33% with combination injuries met criteria for PTSD. PTSD severity scores varied significantly according to type of injury. DISCUSSION: The World War I concept of "shell shock" implied that blast-related injuries were more likely to result in psychological symptoms than were other injuries. These data may support that idea. Circumstance of injury, population differences, and reporting bias could also have influenced the results. CONCLUSION: These results suggest that service members with blunt or combination injuries merit particular attention when screening for PTSD.

Insomnia is the most commonly reported symptom and predicts other symptoms of post-traumatic stress disorder in U.S. service members returning from military deployments.

This study retrospectively reviewed records from current members of the U.S. military who had completed the PTSD Checklist (PCL) at 0 and 3-months after returning from deployments. Insomnia was the most commonly reported symptom of PTSD on the PCL and had the highest average severity scores. At initial screen, 41% of those who had been to Iraq or Afghanistan reported sleep problems. Those who had initially reported any insomnia had significantly higher overall scores for PTSD severity at follow-up than did service members without such a complaint. These results show that insomnia is a particularly frequent, severe, and persistent complaint in service members returning from deployment. Such complaints merit particular attention in relation to the possibility of PTSD.

ADHD, medication and the military service: a pediatrician's dilemma.

CASE: 19-year old male was admitted to a trauma service after falling from a height of 20 feet while rope climbing during military basic training activity. He climbed to the top of the rope but was unable to navigate a series of other activities at the top, became distracted, and fell. He sustained superficial injuries but was admitted to the hospital for observation. An Adolescent Medicine consult was obtained consistent with the trauma service protocol. During that consultation, a comprehensive past medical history was initially negative. On further inquiry however, when asked "Are you supposed to take any medications?" the patient revealed that several years earlier he was diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD). Medication at that time was associated with improvement in school performance. He progressed from being a poor student to successfully completing freshman year at college prior to enlistment. He knew medication for ADHD would prevent enlistment, so he did not reveal the disorder or medication to his recruiter. While obtaining this history the patient was talkative, easily distracted and admitted that his concentration and ability to follow instructions was significantly enhanced on medication. For a consultant, the dilemma became how to handle this potentially important piece of history. Inability to follow instructions may have contributed to this hospitalization and had the potential to put him and his colleagues in greater future jeopardy. Revealing this history might also cause discharge from the military.
