Impression procedures and construction of a sectional denture for a patient with microstomia: a clinical report

This article describes a modified impression procedure and a method of fabricating a 2-piece collapsible denture for a patient with limited oral opening as a result of the resection of a precancerous lesion on the maxillary lip. Fabricating the denture in 2 pieces (a smaller anterior piece and a larger, hinged, collapsible posterior piece) enabled the patient to place and remove the denture

A mandibular fourth molar located in coronoid process

The occurrence of fourth molars in mandible is very rare. A 32 year-old male patient applied to our clinic to seek treatment for a pericoronory abscess distal to the left lower third molar. Radiographic examination revealed an impacted fourth molar located in the coronoid process and a well-defined radiolucency extended downward and forward to retromolar region. Under general anesthesia both third and fourth molars, and the radiolucent cystic lesion between them were surgically removed.The occurrence of fourth molars in mandible is very rare.

Late onset Bartter syndrome: Bartter syndrome type 2 presenting with isolated nephrocalcinosis and high parathyroid hormone levels mimicking primary hyperparathyroidism

Objectives Nephrocalcinosis is associated with conditions that cause hypercalcemia and the increased urinary excretion of calcium, phosphate, and/or oxalate. A monogenic etiology is found in almost 30% of childhood-onset nephrocalcinosis which is also a common manifestation of primary hyperparathyroidism. We discuss a child with nephrocalcinosis and features mimicking primary hyperparathyroidism. Case Presentation A 7-year-old girl presented with nephrocalcinosis. Hypercalciuria, hyperphosphaturia, mild hypercalcemia, hypophosphatemia and elevated parathyroid hormone levels along with normal serum creatinine and absence of hypokalemic alkalosis suggested primary hyperparathyroidism. However, she was ultimately diagnosed with Bartter syndrome type 2 based on the presence of homozygous pathogenic variation in KCNJ1gene. Conclusions This is the second reported case of late-onset Bartter syndrome type 2 without hypokalemic alkalosis. Patients with Bartter syndrome may present with high parathyroid hormone levels and hypercalcemia in addition to hypercalciuria. Thus, the present case suggests that the KCNJ1 gene should be included in genetic analysis even in older children with isolated nephrocalcinosis
