RESUMO
This case study presents a rare case of a 29-year-old woman with spontaneous pneumomediastinum who was treated in the emergency department for subjective dyspnea, rhinitis, and a subjectively reported increasing swelling of the throat. The clinical presentation was only characterized by crepitus in the neck and supraclavicular areas. CT scan of the neck and chest revealed massive emphysema of the soft tissues of the neck, chest, the right side of the face, and pneumomediastinum extending to the diaphragm. Based on the clinical presentation and imaging findings, which were consulted with thoracic surgeons, we assessed the condition as benign spontaneous pneumomediastinum. The patient was treated conservatively and discharged from the hospital on the third day of hospitalization with the need of aftercare.

The aims of this study were to determine concentrations of total homocysteine, cysteine, cysteinylglycine and glutathione in spermatozoa, seminal fluid and blood plasma and to analyse their relationships with sperm parameters. For this reason, a new highly effective method of spermatozoa lysis was developed, using methanol, freezing and subsequent thawing in ultrasonic bath. An HPLC-FD assay was conducted on thiols concentrations in lysed spermatozoa, seminal fluid and blood plasma. Concentrations of thiols in spermatozoa were significantly lower in men with normozoospermia than in samples with pathological semen parameters. Statistical analysis found significant correlations between thiol concentrations in spermatozoa and semen parameters, while the same analysis with thiol concentrations in seminal fluid was substantially less powerful. Only cysteinylglycine concentrations in seminal fluid significantly correlated with pathological semen parameters. No significant differences or correlations were found with blood plasma concentrations.
