Sialolithiasis of the Submandibular Gland

Sialolithiasis of the salivary gland is a benign pathology that occurs most frequently in the submandibular gland because of its anatomic features. Depending on the sialolith size and calcification degree, it can be visible in radiographic examinations. Commonly, patients may experience pain and/or edema, when the ducts are obstructed. The authors report the case of sialolithiasis of the submandibular gland in a 42-year-old, female, white-skinned patient, noticed during routine dental examination. Following diagnosis confirmed by clinical and radiographic examinations, the treatment plan consisted of surgery for removal of the calcified mass. The prognosis is often good, and generally there is no recurrence.

Acute postsurgical suppurative parotitis: current prevalence at Hospital das Clínicas, São Paulo University Medical School

Postsurgical acute suppurative parotitis is a bacterial gland infection that occurs from a few days up to some weeks after abdominal surgical procedures. In this study, the authors analyze the prevalence of this complication in Hospital das Clínicas/São Paulo University Medical School by prospectively reviewing the charts of patients who underwent surgeries performed by the gastroenterological and general surgery staff from 1980 to 2005. Diagnosis of parotitis or sialoadenitis was analyzed. Sialolithiasis and chronic parotitis previous to hospitalization were exclusion criteria. In a total of 100,679 surgeries, 256 patients were diagnosed with parotitis or sialoadenitis. Nevertheless, only three cases of acute postsurgical suppurative parotitis associated with the surgery were identified giving an incidence of 0.0028%. All patients presented with risk factors such as malnutrition, immunosuppression, prolonged immobilization and dehydration. In the past, acute postsurgical suppurative parotitis was a relatively common complication after major abdominal surgeries. Its incidence decreased as a consequence of the improvement of perioperative antibiotic therapy and postoperative support. In spite of the current low incidence, we believe it is important to identify risks and diagnose as quick as possible, in order to introduce prompt and appropriate therapeutic measures and avoid potentially fatal complications with the evolution of the disease.

Considerações atuais da sialolitíase de ducto de glândula submandibular

The sialolithiasis is characterized by the formation of calcified structure called sialolith within the salivary ductal system. Although its etiology is unknown, it is believed that is from the deposition of calcium salts around an accumulation of organic leftovers in the lumen of the duct or be resulted by chronic sialadenitis and partial obstruction. In this study, the authors describe a case of a male patient, 46 years old, brown, who presented the complaint “pain under the tongue.” The presence of a hardened nodule located in the left sublingual fold was observed through intra-oral exam. Current considerations about treatment, clinical and radiographic characteristics were addressed in this work.
