Large non-functioning substernal parathyroid cyst: A case report and review of the literature

Objectives

Presentation of case

Conclusions

•

Parathyroid cysts are rare benign lesions of the head and neck

•

A 65 year-old female with a 6cm cystic neck mass extending to the aortic arch.

•

A mediastinal mass resection showed pathology consistent with a parathyroid cyst.

•

Parathyroid cysts are not often considered on the differential of mediastinal cystic lesions.

Parathyroid cyst: A rare entity

Parathyroid cysts are an uncommon entity. They are classified as functioning and nonfunctioning cysts. Cyst aspiration with detection of parathyroid hormone is a useful tool to confirm the diagnosis. Here, we report four cases of parathyroid cysts. One patient had a functioning cyst. Ultrasonography of the neck revealed a cystic lesion behind the left lobe of the thyroid gland in two cases and a right cystic thyroid nodule in two cases. The cysts exerted a mass effect on the adjacent structures in two cases without clinical compressive symptoms. Fine-needle aspiration with detection of parathyroid hormone in the cyst fluid was performed in one case (nonfunctioning cyst): intracystic parathyroid hormone level was high. Recurrence was noted 1 month after the cyst aspiration. All patients underwent surgical treatment. Our series is characterized by two cases of nonfunctioning intrathyroidal parathyroid cysts which are very uncommon. They are mistaken for thyroid cysts. After surgery, no recurrence was noted. We aim to describe the epidemiological, clinical, and paraclinical features of this condition as well as its therapeutic modalities.

Reduced antibiotic use after initial treatment of acute respiratory infections with phytopharmaceuticals- a retrospective cohort study

OBJECTIVES

We examined the relationship between the initial treatment of acute lower and upper tract respiratory infections with phytopharmaceuticals and the duration of the disease as well as between the initial treatment and the use of antibiotics in the further course of the disease.

METHOD

Outpatients from the IMS® Disease Analyzer database with diagnoses of acute respiratory infections between January 2015 and March 2019 were observed for 30 days. Patients who had been prescribed phytopharmaceuticals on the day of their diagnosis were matched with controls who had not received such prescriptions by treating practice, diagnosis, age, sex, insurance status, index year, and Charlson comorbidity score. Patients antibiotic precriptions on the day of diagnosis were excluded. Logistic regression was used to investigate the relationship between phytopharmaceutical prescription, antibiotic prescription in the further course of the disease, and duration of sick leave.

RESULTS

A total of 117,182 patients who had been prescribed phytopharmaceuticals and an equal number of controls were available for analysis. Phytotherapeutics were associated with fewer antibiotic prescriptions. Extract of Pelargonium sidoides root (odds ratio (OR) 0.49 [0.43-0.57]) and thyme extract (OR 0.62 [0.49-0.76]) exhibited the strongest effect among patients treated by general practitioners, while Pelargonium sidoides root extract (OR 0.57 [0.38-0.84]), thyme and ivy extract (OR 0.66 [0.60-0.73]), and thyme and primrose root extract (OR 0.67 [0.47-0.96]) proved most effective in pediatric patients. Patients receiving phytopharmaceuticals had a significantly lower risk of prolonged periods of sick leave. The risk of sick leave durations of >7 days was most markedly reduced in patients taking cineole (OR 0.74 [0.63-0.86]) and Pelargonium root extract (OR 0.79 [0.54-0.96]).

CONCLUSION

The use of selected phytopharmaceuticals for acute respiratory infections is associated with a significantly reduced need for antibiotic prescriptions in the further course of the disease, as well as significantly shorter sick leaves.
