Severe Pathology

Aeromonas veronii is an emerging pathogen causing severe pathology and mortalities in European seabass aquaculture in the Aegean Sea, Mediterranean. More than 50 strains of the pathogen were characterized biochemically and genetically in order to study the epidemiology of the disease, as well as the phylogeny and virulence of the bacterium. Based on the phenotypic characteristics, the isolates form three groups consisting of: (a) the West Aegean Sea, non-motile, non-pigment-producing strains, (b) the West Aegean Sea, motile, and pigment-producing strains and (c) the East Aegean Sea motile strains that produce minute amounts of pigment. All strains were highly similar at the genomic level; however, the pattern of West/East geographic origin was reflected in biochemical properties, in general genomic level comparison and in the putative virulent factors studied. Type VI secretion system was not detected in the western strains. The outer membrane protein (OMP) profile which contains proteins that are putative antigenic factors, was very similar between strains from the different areas. Although most of the OMPs were detected in all strains with great sequence similarity, diversification according to geographic origin was evident in known antigenic factors such as the maltoporin LamB. A systematic comparative analysis of the strains is presented and discussed in view of the emergence of A. veronii as a significant pathogen for the Mediterranean aquaculture.

Fish Samples

The aim of this study was to analyse the fatty acid composition of European seabass Dicentrarchus labrax (Linnaeus, 1758), farmed in marine cages in the Aegean Sea and in the Black Sea coasts of Turkey. The study was conducted between June 2014 and September 2015 using the same feed in all the cage farms. Fish samples representing the stock were collected at regular intervals and morphometric measurements were taken in the laboratory. Fatty acid analyses were carried out by gas chromatography. Biochemical composition of harvested European seabass indicated high dry matter and crude fat values in the Black Sea region and high crude protein and crude ash values in the Aegean region. Significant regional differences between fatty acid composition (p<0.05) was observed, despite being fed with the same diets.

The Difference

In the present study, monogenean infestations were investigated on the gills of the European seabass Dicentrarchus labrax grown in culture cages located at Yakakent coast of the Black Sea and Milas coast of the Aegean Sea. Parasitological investigations were conducted simultaneously at both localities during September 2014, February and April 2015. While a total of 100 fish specimens were examined from Yakakent samples whose average length was 19.37 cm, a total of 88 fish specimens were examined from Milas samples whose length was 22.67 cm in average. Only one monogenean species Diplectanum aequans was recovered from investigated fish specimens at both sampling localities. Infestation prevalence (%) and mean intensity values of D. aequans were 89.0% and 9.6 ± 0.8 in Yakakent samples while those infestation indices were 90.9% and 13.3 ± 1.2 in Milas samples, respectively. The difference between the infestation prevalence (%) values of D. aequans at both sampling localities was not statistically significant, on the other hand, the difference was statistically significant in the mean intensity values at both locations. Diplectanum aequans showed a homogeneous distribution in all gill arches of fish without any statistically significant difference. This is the first comparative study on the infestation of D. aequans on the gills of European sea bass D. labrax cultured in the Black Sea and the Aegean Sea.

Therapeutic Algorithm

Oesophagectomy is being used in treatment of several oesophageal diseases, most commonly in treatment of oesophageal cancer. It is a major surgical procedure that may result in various complications. One of the most severe complications is anastomotic dehiscence between the gastric conduit and the oesophageal remnant. Anastomotic dehiscence after esophagectomy is directly linked to high morbidity and mortality. We propose a therapeutic algorithm of this complication based on published literature and our experience by retrospective evaluationof 164 patients who underwent oesophagectomy for oesophageal cancer. Anastomotic dehiscence was present in 29 cases.

Objective. Pneumocephalus is a rare complication that often occurs after traumatic skull base injury, leading to morbidity and mortality. Material and Method. We present the case of a 42-year-old healthy man who injured himself when he stuck a metal stick into his left nasal cavity to relieve prolonged nasal obstruction. Immediate cerebrospinal fluid rhinorrhea and subsequent meningitis and pneumocephalus occurred later. He was presented at our hospital with fever and meningeal signs. Result. Computed tomography scans revealed left rhinosinusitis and air collection in the subarachnoid space. The patient received the conservative treatment of bed rest, intravenous hydration, head elevation, and broad-spectrum intravenous antibiotics. Pneumocephalus and meningitis resolved without any surgery, and he experienced no other sequela or complication. Conclusion. Pneumocephalus is a rare incidence and can lead to high morbidity and mortality. Prompt diagnosis and adequate treatment of pneumocephalus and meningitis proved beneficial for our patient who recovered without any complication or surgery.
