Decreasing Function01:27

Decreasing Function

290
A decreasing function describes a relationship where the output consistently declines as the input increases. This means that for any two input values, if one is greater than the other, the corresponding output is smaller. Mathematically, a function f is decreasing on an interval I if for every x1 < x2​ in I, f (x1) > f (x2). This type of behavior is visually identified on a graph that slopes downward from left to right.The nature of a function can be analyzed by calculating...

Decreased Body Temperature01:29

Decreased Body Temperature

1.1K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Decreased pulse rate01:14

Decreased pulse rate

902
Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

Diabetes: Symptoms, Diagnosis, and Complications

2.3K
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...

Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

562
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Gastroesophageal Reflux Disease I: Meaning and Pathophysiology01:29

Gastroesophageal Reflux Disease I: Meaning and Pathophysiology

1.7K
Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...

Summary
This summary is machine-generated.

Voice therapy significantly improved Reflux Symptom Index (RSI) and Voice Handicap Index (VHI-10) scores in patients with muscle tension dysphonia. These findings suggest that voice therapy can effectively treat symptoms often misdiagnosed as laryngopharyngeal reflux disease.

Area of Science:

  • Otolaryngology
  • Speech-Language Pathology

Background:

  • Muscle tension dysphonia (MTD) patients often present with elevated Reflux Symptom Index (RSI) and Voice Handicap Index (VHI-10) scores.
  • These symptoms can lead to misdiagnosis as laryngopharyngeal reflux (LPR) disease, prompting inappropriate treatment with antireflux medications.

Purpose of the Study:

  • To assess the impact of voice therapy on RSI and VHI-10 scores in patients with MTD.
  • To determine if voice therapy can alleviate symptoms commonly attributed to LPR in non-responsive cases.

Main Methods:

  • A retrospective cohort study was conducted involving 18 patients with dysphonia unresponsive to proton pump inhibitors.
  • Patients received at least three voice therapy sessions without concurrent antireflux therapy.
  • Changes in RSI and VHI-10 scores were analyzed from initial to follow-up visits.

Main Results:

  • A significant decrease in median RSI scores (18.5 to 10.5, P=.02) and VHI-10 scores (25.5 to 13.5, P=.03) was observed post-voice therapy.
  • An inverse correlation was found between the frequency of voice therapy sessions per month and the change in RSI scores (r=-0.4, P=.05).

Conclusions:

  • Voice therapy led to significant improvements in self-reported reflux and voice handicap symptoms in patients with MTD.
  • The study suggests that symptoms mimicking LPR may stem from inefficient voice use or anxiety, which are treatable with voice therapy.
