Since its introduction in 1960, the combined oral contraceptive pill has become the dominant reversible contraceptive technology for controlling female fertility in spite of early and ongoing ethical, critical medical, and societal disapproval. Over the last decade, prescription rates among young women in Western Europe have declined alongside the rise of social media use. This article investigates the mechanisms underlying this change in contraceptive choices and the role played by social media in this trend.

Pseudomembranous conjunctivitis, caused by inflammation of the conjunctiva, is characterized by conjunctival injection, mucopurulent discharge, and formation of a thin membrane overlying the conjunctiva. This is often caused by a viral or bacterial infection. This case report discusses pseudomembranous conjunctivitis from in a newborn infant which, to our knowledge, has not been reported in relevant literature.

Article Synopsis
  • This study assessed the implementation of MendelScan, a tool designed to find rare diseases in a UK primary care setting, addressing challenges like complexity and low physician awareness in diagnosing these conditions.
  • The process involved analyzing data from 68,705 patients, using algorithms to flag potential cases based on medical records, leading to a clinical review of flagged patients to identify those needing further investigation.
  • Out of the flagged cases, 75 records passed the review, resulting in 36 reports sent to GPs, with some categorized as possible diagnoses and others excluded due to existing clear diagnoses.

Article Synopsis
  • Bone grafting from the calcaneus (heel bone) is effective in foot and ankle surgery due to its easy access and good blood supply.
  • This study used fresh-frozen cadaver limbs to analyze the volume of cancellous bone that can be harvested while identifying safe anatomical zones and risks to nearby nerves and blood vessels.
  • Findings showed that an average of 0.85 cc of bone could be obtained with a small incision, and no damage to nerves was detected, suggesting this method could enhance surgical outcomes.

Introduction: Cytomegalovirus (CMV) anterior uveitis is a recognised cause of anterior uveitis in immunocompetent patients and is preventable cause of vision loss. Ocular sequelae include corneal endothelial damage which can cause corneal oedema and failure, as well as glaucoma. Recurrences of inflammation are common and therefore patients are often exposed to long-term therapy.

Purpose Of Review: Vitreoretinal lymphoma (VRL) is well known as a masquerade syndrome. However, delays in diagnosis are common particularly because of the small volume of tissue that is used for investigative studies. We outline the current diagnostic tests available to clinicians and provide a glimpse of possible future novel diagnostics.

Introduction: There has been a surge of interest in the area of bias in industry-supported continuing medical education/continuing professional development (CME/CPD) activities. In 2007, we published our first study on measuring bias in CME, demonstrating that our assessment tool was valid and reliable. In light of the increasing interest in this area, and building on our experience, we wanted to further understand the application of this tool in different environments.

Introduction: The pharmaceutical industry, by funding over 60% of programs in the United States and Canada, plays a major role in continuing medical education (CME), but there are concerns about bias in such CME programs. Bias is difficult to define, and currently no tool is available to measure it.

Methods: Representatives from industry and academia collaborated to develop a tool to illuminate and measure bias in CME.

Objective: The use of interactive videoconferencing to provide psychiatric services to geographically remote regions, often referred to as telepsychiatry, has gained wide acceptance. However, it is not known whether clinical outcomes of telepsychiatry are as good as those achieved through face-to-face contact. This study compared a variety of clinical outcomes after psychiatric consultation and, where needed, brief follow-up for outpatients referred to a psychiatric clinic in Canada who were randomly assigned to be examined face to face or by telepsychiatry.

Although duration of untreated psychosis (DUP) predicts treatment outcome as assessed by symptoms in first-episode psychosis, there is much less evidence concerning its relation to social functioning. We present the results of a prospective study of 163 first-episode psychosis patients examining occupational activity at three years, after initiation of treatment. Both shorter DUP and higher social support were significantly associated with more full time occupational activity at follow-up.

Background: The evidence regarding the independent influence of duration of untreated psychosis (DUP) on rate and time to remission is far from unequivocal. The goal of the current study was to examine the role of predictors for rate and time to remission in first-episode psychosis (FEP).

Method: The differential effect of age, gender, age of onset, duration of untreated psychosis (DUP), duration of untreated illness (DUI), pre-morbid adjustment, co-morbid diagnosis of substance abuse and adherence to medication on the rate of and time to remission were estimated using a logistic and Poisson regression, and survival analysis respectively, in FEP patients.

This paper presents the first published findings examining the relationship of social support to three-year symptom outcome and hospitalizations for a group of first episode patients with psychotic disorders. Social support was measured using items from the provider version of the Wisconsin Quality of Life Scale as assessed at the time of initiation of treatment for 113 patients. Outcome was assessed by level of positive and negative symptoms at three-year follow-up and number of psychiatric admissions during those three years.

Objective: To use functional magnetic resonance imaging (fMRI) to investigate functional connectivity, and hence, underlying neural networks, in never-treated, first-episode patients with schizophrenia using a word fluency paradigm known to activate prefrontal, anterior cingulate, and thalamic regions. Abnormal connectivity between the prefrontal cortex (PFC) and other brain regions has been demonstrated in chronic, medicated patients in previous positron emission tomography (PET) studies, but has not to our knowledge, previously been demonstrated using both first-episode, drug-naïve patients and fMRI technology.

Methods: A 4.
