Introduction: A multitude of mechanisms have been implicated in the pathophysiology of epilepsy. Objective: To assess mean daily plasma concentrations of ACTH, Cortisol, DHEAS, leu-enkephalin, and beta-endorphin in epileptic patients with complex partial seizures evolving to tonic-clonic in relation to frequency of seizure occurrence (groups with seizure occurrences - several per week and several per year) and duration of the disease (groups less than and more than 10 years). We decided to analyse mean daily values of beta-endorphin and leu-enkephalin because of significant differences in concentrations of these substances in blood during the day. Material and methods: The study was performed on 17 patients (14 males + 3 females; mean age 31.8 yrs) treated with carbamazepine (300-1800 mg/day). The control group consisted of six age-matched healthy volunteers. Blood was collected at 8 a.m., 2 p.m., 8 p.m., and 2 a.m. Intergroup analysis was performed with the use of ANOVA Kruskal-Wallis test. Results: Mean daily concentrations of ACTH and Cortisol in the blood of the patients with epilepsy were higher in comparison with those of the healthy volunteers, independently of the frequency of seizures and duration of the disease. Mean daily concentrations of beta-endorphin in the blood of the patients with epilepsy were higher in the groups of patients with more severe clinical course of disease (with more frequently occurring epilepsy seizures and longer duration of the disease) in comparison with healthy subjects. Mean daily concentrations of leu-enkephalin in the blood of the patients with epilepsy were higher in the group of patients with short duration of the disease in comparison with the group with long duration of the disease. Conclusions: 1. Pituitary-adrenal axis hyperactivity is observed in patients with clinically active epilepsy, independently of the frequency of seizures and duration of the disease. 2. Changes in endogenous opioid system activity are related to the clinical activity of epilepsy - beta-endorphin concentrations are connected with frequency of seizures and duration of the disease and leu-enkephalin concentrations with duration of the disease. 3. Endogenous opioid peptides might take part in the neurochemical mechanism of human epilepsy. Source

Germ cells tumours most frequently occur in the gonads. Extragonadal localisation is rare and concerns mainly the mediastinum, retroperitoneum and pineal. We present the first description of a patient with a mixed germ cells tumour located primarily in the thyroid. A 35-year-old man in a good clinical condition was admitted to diagnose metastasis revealed in an X-ray of his lungs. Abnormal laboratory tests showed high concentrations of beta-HCG and LDH. Ultrasound examination revealed: hypoechogenic area 8 x 4 x 5 mm in the left testicle, and enlarged left thyroid lobe with echogenically heterogenous mass. In cytological examination of the thyroid, carcinomatous cells were found, which suggested metastasis. A diagnosis of cancerous spread of testicular cancer to the lungs and thyroid was made. The left testicle, with spermatic cord, was removed, yet in the histopathological examination no carcinomatous cells were found. Rescue chemotherapy, according to the BEP scheme (bleomycin, etoposide, cisplatin) was started, but during its course the patient died. Histopathology disclosed primary mixed germ cells tumour in the thyroid, predominantly with carcinoma embryonale and focuses of choriocarcinoma. Extragonadal germ cells tumours rarely occur in the thyroid. In medical literature, some cases of teratomas and a single case of yolk sac tumour in the thyroid have been described. The presence of choriocarcinoma was responsible for the high serum concentration of beta-HCG. Surgery of germ cells tumours proves insufficient. The conventional chemotherapy is based on cisplatin. In conclusion, extragonadal germ cells tumours are rare, but should be considered while co-existing with elevated markers such as: AFP, beta-HCG and lack of abnormalities in the gonads. Source

Background: Several studies have assessed natriuretic peptides in patients with thyroid disorders, and these studies have provided contrasting results. This difference may be partially explained by the presence of concomitant disorders of the cardiovascular system in participants. Material and methods: The study included 101 patients free of any cardiovascular disorder, who, on the basis of plasma levels of TSH and thyroid hormones, were divided into patients with overt hyperthyroidism, patients with subclinical hyperthyroidism, patients with overt hypothyroidism, patients with subclinical hypothyroidism, and control subjects with normal thyroid profile. Hyperthyroidism was induced either by nodular thyroid disease or by Graves' disease, while hypothyroidism was secondary to autoimmune thyroiditis or surgery. Results: Compared to control subjects, hyperthyroid patients were characterised by higher plasma levels of NT-pro-BNP. This increase was particularly pronounced in cases of overt disease. On the other hand, neither clinical nor subclinical hypothyroidism was associated with any significant changes in this peptide. Plasma levels of NT-pro-BNP did not differ between patients with Graves' disease and toxic nodular goitre nor between patients with autoimmune hypothyroidism and hypothyroidism secondary to thyroidectomy. Only L-thyroxine substitutions, but not hyperthyroidism treatment, caused changes in plasma concentration of NT-pro-BNP. Conclusions: Hyperthyroidism and hypothyroidism induce changes of the plasma concentration of NT-pro-BNP. Although both exogenous L-thyroxine and antithyroid drugs restored thyroid function, only the former drug changed plasma NT-pro-BNP content. The thyrometabolic state of a patient should always be taken into consideration when NT-pro-BNP is assessed as a marker of cardiac dysfunction. Source
