Article Abstract
Objective: To evaluate the feasibility and clinical outcomes of computer-guided injection of sodium hyaluronate visco-supplementation and arthrocentesis in the treatment of temporomandibular joint disorder compared with conventional injection.
Study Design: Twenty patients with Wilkes stage I & II internal derangement were selected and randomly allocated into the intervention group, managed with computer-guided intra-articular visco-supplementation, and the control group, managed with conventional technique. The efficacy of the computer-guided procedure was appraised by the assessment of the need for needle relocation and the duration of the procedure in both groups. Clinical evaluation was performed for the assessment of pain intensity, maximum unassisted vertical mouth opening, and maximum lateral mandibular deviation during opening in both groups.
Results: Computer-guided group demonstrated a statistically significant difference from the free-hand group regarding the total procedural time and number of needle relocations. The guided group didn't require any needle relocation with a mean procedural time of 8.35 ± 0.47 minutes. All patients in both groups reported immense improvement in all clinical parameters, with no statistically significant difference between the two groups.
Conclusions: The use of computer-guided visco-supplementation for the treatment of internal derangement is a promising practice with improvement in the procedural accuracy and effectiveness of the injectable material. Additionally, it makes the procedure more reproducible and simpler for both clinicians and patients.

Morning Larks and Night Owls: Considering Chronotype in Evaluation of Patients with Pulmonary Hypertension.
Ann Am Thorac Soc

University of Florida, Department of Medicine, Gainesville, Florida, United States;
Background: Pulmonary hypertension (PH) is a systemic illness with increasingly subtle disease manifestations including sleep disruption. Patients with PH are at increased risk for disturbances in circadian biology, although to date there is no data on "morningness" or "eveningness" in pulmonary vascular disease.
Research Questions: Our group studied circadian rhythms in PH patients based upon chronotype analysis, to explore whether there is a link between circadian parameters and physiologic risk-stratifying factors to inform novel treatment strategies in patients with PH?
Study Design And Methods: We serially recruited participants from July 2022 to March 2024, administering in clinic the Munich Chronotype Questionnaire (MCTQ).
Effects of therapeutic exercise in patients with internal derangement of the temporomandibular joint: A prospective study.

This study examines the symptomatic and clinical features and variations in characteristics, such as angle and length of the condylar path in the sagittal plane during protrusion movement, in internal derangement patients treated with exercise therapy. Patients were selected and classified using the diagnostic criteria for temporomandibular disorders (DC/TMD) axis I. The therapeutic exercise program consisted of lateral jaw movements performed daily, with gradual progression to a target of 50 repetitions per day.

Metformin, a first-line agent in the treatment of type 2 diabetes mellitus, is widely favored for its efficacy and safety profile; however, under conditions of impaired renal function, it can lead to metformin-associated lactic acidosis (MALA), a rare but life-threatening complication. The diagnosis requires careful exclusion of other causes of lactic acidosis, such as sepsis or hypoperfusion, which can mimic MALA. We present a case of an 88-year-old female with type 2 diabetes and chronic kidney disease (CKD) stage III who developed severe lactic acidosis and encephalopathy in the setting of acute kidney injury and recent infection.

Acutely decompensated heart failure (AHF) is a severe, multifactorial syndrome with acute symptom worsening, which poses a great challenge for healthcare professionals worldwide. AHF admissions are responsible for a high percentage of morbidity, mortality, and healthcare utilization, particularly in elderly comorbid patients. The pathophysiology, clinical presentation, and treatment of AHF are presented in this review, emphasizing neurohormonal activation, hemodynamic derangements, and comorbidities such as chronic kidney disease, chronic obstructive pulmonary disease, and atrial fibrillation.

Despite its clinical significance, the prevalence and spectrum of thyroid dysfunction among South Asian patients with T2DM remain incompletely characterized. This study aimed to determine the frequency and types of thyroid dysfunction in patients with T2DM and to examine its associations with demographic characteristics, glycemic control, metabolic parameters, and microvascular complications.
