OBJECTIVES: Pituitary abscess is rare disease and the correct diagnosis is difficult because there are non-specific symptoms and it is often radiologically indistinguishable from other pituitary lesions.

CASE PRESENTATION: We present one case of pituitary abscess that constitute 0.15% of all pituitary adenomas operated in our department in the 20 years. A 49-year-old woman presented with a history of 10 months bifrontal headache. The MRI showed cystic intra and suprasellar mass with ring enhancement after contrast injection. During transsphenoidal surgery, copious yellowish pus was found. Antibiotic therapy was performed. Histological study of the cyst wall confirmed the diagnosis of pituitary abscess.

CONCLUSION: Pituitary abscess should be considered in the differential diagnosis of all other cyst mass in patients with diabetes insipidus....

: Environmental factors can play an important role in the development of autoimmune thyroiditis (AT) and other autoimmune diseases. This article reviews the role of heavy metals and infectious agents in AT. Currently, the genes responsible for a metal-induced pathology are known in experimental animals but similar knowledge is lacking in man. Metals such as nickel or mercury induce delayed type T cell hypersensitivity (allergy) which is relatively common, especially in women. T-cell allergy can be studied with the lymphocyte transformation test, LTT-MELISA. It has been found that patients with AT and other autoimmune diseases, such as multiple sclerosis, psoriasis, systemic lupus erythematosus and atopic eczema, show increased lymphocyte reactivity in vitro to inorganic mercury, nickel and other metals compared to healthy controls. The important source of mercury is dental amalgam. Replacement of amalgam in mercury-allergic subjects resulted in improvement of health in about 70% of patients. Several laboratory parameters such as mercury-specific lymphocyte responses in vitro and anti-thyroid autoantibodies were normalized as well. In contrast, no changes in health and laboratory results were observed in mercury-allergic patients who did not have their amalgams replaced. The same was true for non-allergic patients who underwent amalgam replacement. Infectious agents such as Helicobacter pylori (Hp) may cause chronic inflammation and autoimmune reactivity in susceptible subjects. The results of in vitro experiments performed with lymphocytes from Hp infected patients indicate that Hp can cause immunosuppression which might be eliminated by successful eradication therapy. In conclusion, heavy metals and Hp infection may play an important role in AT. Laboratory tests, such as LTT-MELISA, can help to determine the specific etiological agents causing inflammation in individual patients. The treatment of AT and other autoimmune diseases might be improved if such agents are eliminated and any future exposure restricted....

OBJECTIVES: The present study was aimed at evaluation of the response of Japanese quails to cyanobacterial biomass administered in feed using biochemical profiles and parameters of reproduction.

DESIGN: Effects of cyanobacterial biomass were studied according to the OECD 206 Guideline on Avian Reproduction Toxicity. A total of 16 control and 16 experimental pairs (32 males and 32 females) were analyzed. The chronic exposure of parent birds lasted eight weeks with the daily sum of 61.62 microg MCs including 26.54 microg MC-RR, 7.62 microg MC-YR and 27.39 microg MC-LR.

RESULTS: There was no mortality both in control and cyanobacterial-biomass-exposed adults during the present study. Nor did the birds show any clinical signs of intoxication. Lactate dehydrogenase activity was increased about three-fold in exposed birds. No other biochemical parameters were showing significant differences. A total of 824 and 821 eggs were laid by control and exposed birds, respectively, during the eight-week study period. Eggs laid by cyanobacterial-biomass-exposed hens had lower weight than in controls (11.99+/-1.13g and 12.40+/-1.27g, respectively; p<0.01). Egg viability, hatchability, and the effect of hatching in control and experimental birds were 79.6+/-9.3 and 86.8+/-8.2% (p<0.05), 83.2+/-12.6 and 90.1+/-9.3%, and 65.2+/-17.7 and 77.7+/-15.2% (p<0.05), respectively. There was also a statistically significant difference in the number of 14-day old survivors per hen per day in control and experimental birds (0.38+/-0.02 and 0.43+/-0.01 %, respectively).

CONCLUSION: The lower weight of eggs produced by exposed parental hens was not reflected in their biological quality. On the contrary, reproductive parameters in cyanobacterial-biomass-exposed birds were better than in the control group. It might be hypothesized that compounds of hormonal activity could be present in the complex cyanobacterial biomass. However, further research into this issue is necessary....

OBJECTIVES: The aim of the present study was to evaluate differences between juvenile and adult Japanese quails in responses to the exposure to cyanobacterial biomass in the diet.

DESIGN: The OECD 205 Guideline on Avian Dietary Toxicity Test (1984) was employed in the experiment. A total of 75 freshly hatched chicks and 30 adults were exposed to cyanobacterial biomass for 15 days and blood sampled daily and on days 5, 10 and 15, respectively. Japanese quail chicks and adults received the same daily dose of approximately 224.4 ng microcystins per gram of body weight. Biochemical responses were compared against controls.

RESULTS: No Japanese quail chicks and adults died during the acute 15-day-cyanobacterial-biomass exposure. Biochemical responses to the biomass in diet were first observed from day 5 post exposure to cyanobacterial biomass both in chicks and adults and there were age-related differences in the parameters changed. The responses of adult birds included an increase in lactate dehydrogenase, a drop in glucose and the total antioxidant capacity as well as a 15 to 20 % inhibition of acetylcholinesterase activity. Japanese quail chicks exposed to cyanobacterial biomass for the first 15 days after hatching reacted by having hypoproteinaemia, increased concentrations of triglycerides, uric acid and the total antioxidant capacity and a drop in high-density lipoprotein cholesterol in the blood.

CONCLUSIONS: Chicks were not found to be more susceptible to the effects of biomass exposure. It seems that, due to their physiological preparation for the oxidative stress associated with hatching, Japanese quail chicks were even better able to cope with the cyanobacterial-biomass-induced oxidative stress than adults....

OBJECTIVES: The aim of this study is to assess the toxicity of PAX-18 in different developmental stages of common carp (Cyprinus carpio). The preparation PAX-18, with its active ingredient polyaluminium chloride (9% of Al), is a coagulation agent that is used mainly to precipitate phosphates, to prevent surface water eutrophication and incidences of cyanobacteria. It is applied to the water environment and thus could present a potential risk to fish.

DESIGN: The toxicity tests were performed on common carp according to OECD (203, 210) methodologies. The acute toxic effect was evaluated for juveniles and the early development stage effect was observed in embryo-larval toxicity tests. The results of the toxicity tests (the number of dead individuals at particular test concentrations) were subjected to a probit analysis using an EKO-TOX 5.2 programme to determine the LC50 values of PAX-18.

RESULTS: Acute toxicity value expressed as 96hLC50 was 753.1 +/- 24.3 mg.l-1 (67.8 mg.l-1 Al). Effect on early development stage expressed as the no observed effect concentration was 10 mg.l-1 (0.9 mg.l-1 Al), the lowest observed effect concentration was 50 mg.l-1 (4.5 mg.l-1 Al). No significant effects of the preparation PAX-18 in concentrations of 50 mg.l-1 of PAX-18 and lower were found on hatching, length and weight parameters, morphology and histopathology.

CONCLUSION: The lethal concentration of PAX-18 found in acute toxicity tests on common carp was 7-14 times higher than the concentration which is usually applied to water (5-10 mg.l-1 Al). Moreover, fish in eutrophicated water sources are exposed to PAX-18 concentrations corresponding with the lowest observed effect concentration only for a short time, therefore the effect on them can be considered as minimal....

: Cyanotoxins are the metabolites of cyanobacteria, belonging to different chemical groups and of diverse mechanisms of toxicity. Generally, they are divided into hepatotoxins, neurotoxins and dermatotoxins/irritant toxins. There is a growing evidence, that besides the above mentioned toxicity, exposure to cyanotoxins may also induce other effects, among others the disruption of neuroendocrine and immune systems. The purpose of that paper is to sum up the current information obtained from the literature and from our own studies about the influence of cyanohepatotoxins on neuroendocrine and immune systems of fish. From the presented data it appears, that microcystins, nodularin and cylindrospermopsin, except for their hepatotoxic activity, are potent to exert such effects as HPI axis activation resulting in physiological and behavioural changes, disturbances in thyroid hormones release/metabolism, as well as impairment of immune responses in fish. However the studies in that area are still incomplete and many questions remain to be answered, especially what consequences for fish population health status it brings....

BACKGROUND: There is now evidence that an increased translocation of LPS from gram negative bacteria with subsequent gut-derived inflammation, i.e. induction of systemic inflammation and oxidative & nitrosative stress (IO&NS), is a new pathway in chronic fatigue syndrome (CFS).

METHODS: The present study examines the serum concentrations of IgA and IgM to LPS of gram-negative enterobacteria, i.e. Hafnia Alvei; Pseudomonas Aeruginosa, Morganella Morganii, Pseudomonas Putida, Citrobacter Koseri, and Klebsielle Pneumoniae in CFS patients both before and after intake of natural anti-inflammatory and anti-oxidative substances (NAIOSs), such as glutamine, N-acetyl cysteine and zinc, in conjunction with a leaky gut diet during 10-14 months. We measured the above immune variables as well as the Fibromyalgia and Chronic Fatigue Syndrome Rating Scale in 41 patients with CFS before and 10-14 months after intake of NAIOSs.

RESULTS: Subchronic intake of those NAIOSs significantly attenuates the initially increased IgA and IgM responses to LPS of gram negative bacteria. Up to 24 patients showed a significant clinical improvement or remission 10-14 months after intake of NAIOSs. A good clinical response is significantly predicted by attenuated IgA and IgM responses to LPS, the younger age of the patients, and a shorter duration of illness (< 5 years).

DISCUSSION: The results show that normalization of the IgA and IgM responses to translocated LPS may predict clinical outcome in CFS. The results support the view that a weakened tight junction barrier with subsequent gut-derived inflammation is a novel pathway in CFS and that it is a new target for drug development in CFS. Meanwhile, CFS patients with leaky gut can be treated with specific NAIOSs and a leaky gut diet....
