Establishment of a Registry of Patients With Parathyroid Disease

Primary outcomes

1. Longitudinal Biochemical Monitoring in Patients with Parathyroid Pathology

   Time frame: through study completion, an average of 15 years

   This outcome measure will specifically assess and report biochemical parameters in patients with parathyroid pathology under the care of the O.U. Endocrinology. Key biochemical markers to be measured include:

   Serum calcium levels (mmol/L) Serum phosphorus levels (mmol/L) Parathyroid hormone (PTH) levels (pg/mL) Vitamin D levels (ng/mL) Each parameter will be measured at baseline and at predefined intervals throughout the study. The collected data will be summarized as means ± standard deviations for continuous variables or as proportions for categorical data, where appropriate.

2. Clinical Outcomes in Parathyroid Pathology: Symptom Severity, Biochemical Parameters, and Comorbidities

   Time frame: through study completion, an average of 15 years

   This outcome measure includes the assessment of multiple clinical parameters related to parathyroid pathology. These include:

   Symptom Severity: Assessed using a standardized symptom severity scale, reported as a score.

   Biochemical Parameters: Measurement of serum calcium levels (mg/dL) and parathyroid hormone (PTH) levels (pg/mL), summarized as means ± standard deviation.

   Comorbidities: Documented as binary variables (present/absent) and reported as prevalence percentages.

3. Radiological Assessments in Parathyroid Pathology: Imaging Findings and Anatomical Evaluation

   Time frame: through study completion, an average of 15 years

   This outcome measure involves the collection and evaluation of radiological data to assess the anatomical and functional status of the parathyroid glands and related structures. Specific assessments include:

   Ultrasound Findings: Measurement of gland size (in centimeters) and structural abnormalities.

   CT and MRI Results: Detection of anatomical changes or lesions, reported as present/absent and described qualitatively.

   Bone Scans: Evaluation of bone metabolism abnormalities, summarized as binary outcomes (normal/abnormal).

   Each imaging modality will be analyzed and reported independently, with results summarized based on specific Units of Measure, such as size (cm) or qualitative descriptors.

4. Medico-Nuclear Outcomes: Parathyroid Imaging and Functional Assessment

   Time frame: through study completion, an average of 15 years

   This outcome measure focuses on data obtained from nuclear medicine imaging to evaluate parathyroid gland function. Specific assessments include:

   Sestamibi Scan Results: Reported as qualitative findings (e.g., positive/negative for abnormal uptake) and quantified when applicable (e.g., uptake percentage).

   Additional Imaging Modalities: Data from parathyroid-specific imaging (e.g., PET/CT or ultrasound) will include quantitative parameters such as gland size (cm³) and uptake intensity scores.

   Each imaging modality will be analyzed and reported separately using appropriate Units of Measure. Aggregation methods will be clarified if data from multiple imaging types are combined to inform a single outcome metric.

5. Histopathological Characteristics of Parathyroid Pathology

   Time frame: through study completion, an average of 15 years

   This outcome measure focuses on the collection and analysis of histological data from tissue samples. Specifically:

   Biopsy Results: Histopathological features will be described qualitatively (e.g., presence of adenoma, hyperplasia) and quantitatively (e.g., cell counts, mitotic index per high-power field).

   Post-Surgical Tissue Analysis: Includes structural characteristics such as tissue size (measured in millimeters), cellular composition, and presence of fibrosis or calcifications.

   Each type of histopathological finding will be documented and analyzed independently, with appropriate Units of Measure used for quantitative assessments. Aggregated data will be summarized to provide insights into the cellular and structural characteristics of parathyroid pathology.
