Relationship Formation

46.2K
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Social Relationships and Well-Being

The significance of social relationships in psychological well-being is a well-established area of inquiry within social psychology. Research consistently demonstrates that the presence of meaningful, supportive relationships enhances emotional health, while the absence or deterioration of such connections can contribute to psychological distress. Relationships serve as a foundation for emotional support, identity, and social belonging, all of which are critical to an individual’s overall...

Area of Science:

  • Otolaryngology
  • Dentistry
  • Neurology

Background:

  • Temporomandibular disorder (TMD) patients often experience symptoms affecting the jaw, muscles, and ears.
  • Anatomical proximity between the temporomandibular joint, trigeminal nerve, and ear structures may explain these otological symptoms.
  • Common otological symptoms include tinnitus, ear fullness, pain, hearing loss, hyperacusis, and vertigo.

Purpose of the Study:

  • To determine the prevalence of otological symptoms in patients diagnosed with TMD.
  • To analyze the association between TMD and various ear-related complaints.
  • To evaluate the frequency of specific otological symptoms within a TMD patient cohort.

Main Methods:

  • Retrospective analysis of 485 patient medical records from the CDATM/UTP.
  • Data collected included patient demographics (gender, age) and reported otological symptoms.
  • Statistical analysis was performed using SPSS (IBM Statistic 20.0) after ethics committee approval.

Main Results:

  • The study identified a higher prevalence of TMD in female patients aged 41-50.
  • A significant 87% of TMD cases reported otological symptoms, irrespective of sex or age.
  • Tinnitus was the most prevalent symptom (42%), followed by ear fullness (39%).

Conclusions:

  • The findings strongly support a correlation between temporomandibular disorders and otological symptoms.
  • Otological symptoms in TMD patients may occur even if not directly caused by an ear pathology.
  • This highlights the importance of considering TMD in the differential diagnosis of ear complaints.
