SaliVISION: a rapid saliva-based COVID-19 screening and diagnostic test with high sensitivity and specificity.

The Coronavirus disease 2019 (COVID-19) pandemic-caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)- has posed a global threat and presented with it a multitude of economic and public-health challenges. Establishing a reliable means of readily available, rapid diagnostic testing is of paramount importance in halting the spread of COVID-19, as governments continue to ease lockdown restrictions. The current standard for laboratory testing utilizes reverse transcription quantitative polymerase chain reaction (RT-qPCR); however, this method presents clear limitations in requiring a longer run-time as well as reduced on-site testing capability.

OEDIPUS REX: WHERE ARE WE GOING, ESPECIALLY WITH FEMALES?

The Oedipus myth usefully informs triangulated object relations, though males, females, and "humankind" can become overly interchangeable. Freud's intentions to enlighten sexed gender are nowadays obscured. In 1931, he rejected Oedipus for females.

The sense of self in anorexia-nervosa patients: a psychoanalytically informed method for studying self-representation.

This paper has two purposes: to study a central psychological feature of anorexia nervosa, the disturbed sense of self, and to demonstrate the utility of an empirical research method to explore a psychoanalytic concept such as self-representation. The aim of the study was to distinguish the sense of self of anorexia-nervosa patients from that of other psychiatric patients, as well as from non-patients. We obtained open-ended self-descriptions, which provide access to self-representations, from 77 young women between the ages of 14 and 24 who made up three groups-anorexia-nervosa patients (n = 15), control psychiatric patients (n = 15), and control non-patients (n = 48).

Thoughts on hate and aggression.

The phenomenon of hate is explored from two perspectives: in terms of intensive bodily arousal and mobilization, and as a form of active but paralyzed aggression. Aggression, in this context, is viewed not in terms of discharges of drive energies but rather as reinforced effort aimed at the removal or destruction of barriers that impede the organism's movement, in real or symbolic space. Winnicott (1950) already had emphasized how the basic fact of the child's motility, its activity, lies at the source of what becomes aggression.

Cobalamin-responsive disorders in the ambulatory care setting: unreliability of cobalamin, methylmalonic acid, and homocysteine testing.

Early recognition of cobalamin (Cbl)-responsive disorders in the ambulatory care setting is essential to prevent irreversible neurologic deficits. However, diagnostic algorithms using Cbl, methylmalonic acid (MMA), and homocysteine (HCys) measurements reflect studies in academic centers, and their negative predictive values have not been established. Thus, records of 456 ambulatory patients evaluated for Cbl deficiency at a staff model HMO were reviewed.

Viral hepatitis: primary care diagnosis and management.

Many patients in primary care settings have hepatitis. This article discusses signs and symptoms of acute hepatitis and outlines differential diagnoses. The characteristics and methods of transmission of individual hepatotropic viruses, including hepatitis A, B, C, D, E, and G/GB-C are reviewed.

Patellofemoral malalignment.

Anterior knee pain represents one of the most common musculoskeletal complaints of adolescents. It is a disorder in which there is broad clinical experience and yet it represents a difficult and frustrating entity for the athlete to endure and for the physician to treat. An appropriate clinical examination and selected diagnostic studies can define the diagnosis and the introduction of conservative therapy usually will correct the problem.

Perceived-competence deficit in anorexia nervosa.

Anorexia nervosa patients are portrayed as competent and accomplished and yet they feel ineffective and diffident. The assessment of this aspect of their self-esteem presents methodological problems. The Interests and Abilities Questionnaire was designed to measure interests and perceived abilities in typical adolescent activities.

Transverse tibial stress fractures. A special problem.

Five transverse tibial stress fractures have been reviewed. Two of three cases in the anterior midtibia and one in the proximal posteromedial tibia had radionuclide scans. These cases demonstrated minimal scan activity at the stress fracture site.
