Experimental Sampling

Individuals of the tilapia species Oreochromis niloticus niloticus(Linnaeus, 1758) were caught in Lesina Lagoon during experimental sampling for the shrimp Penaeus kerathurus using fyke net traps from December 1999 to September 2000. The species O. niloticusis not native in Italian coastal waters, although attempts of tilapia culture in land-based aquaculture farms were occasionally carried out in the past. The number of individuals captured in the samples suggests a colonization of the area of Lesina lagoon. The highest catches were observed during July. In July, the individuals caught represented the 22.3±4.1 % of the total catch weight. Such colonization of a marine environment byO. niloticusniloticus is the first case reported for Italy. The occurrence of the species in Lesina lagoon is attributed to fish which escaped from fish farms in the area and entered the lagoon through the numerous streams and irrigation-drainage channels that outflow along the south coastline.

Objective: To study the incidence and seasonal dynamics of different fungi affected freshwater fishes in Lake Manzala with molecular identification of the isolated fungi. Animals: 300 Nile tilapia (Oreochromis niloticus) and 300 catfish (Clarias gariepinus). Design: Descriptive study. Procedures: Random samples of Oreochromis niloticus (O. niloticus) and Clarias gariepinus (C. gariepinus) were collected from Manzala fish farms. Clinical and postmortem examination of fish was applied. Isolation and identification of different fungi were performed by conventional methods. Furthermore, the molecular characterization of isolated fungi was carried out. Results: C. gariepinus had a higher rate of infection with different fungal species than O. niloticus. Aspergillus spp. (Aspergillus niger and Aspergillus flavus) were the most fungal isolated from the examined fishes, followed by Penicillium spp. and Candida albicans. Aspergillus spp were detected in all seasons with a higher rate in summer and spring. A. flavus, A. niger, Penicillium spp. and C.albicans isolates were amplified from both C. gariepinus and O. niloticus at the specified molecular weight using PCR. Conclusion and clinical relevance: Fungal infection affected the fish showing different external and internal lesions, all species of Aspergillus were found in all seasons with a high rate in, hot seasons, summer and spring. The Prevalence of Penicillium and C. albicans were also reported. All fungal isolates were identified on the phenotypic and molecular bases.

Lymphoplasmacytic Infiltrate

Most malignant tumors of the penis are squamous cell carcinomas (SCC), being divided in 2 groups, one human papillomavirus (HPV)-related and another non-HPV-related, with lymphoepithelioma-like carcinoma (LELC) being one of the rarest HPV-related SCC. In this article, we report a case of a 50-year-old man who presented testicular swelling and pain for the past 3 months. A penile mass was identified, and the patient was submitted to a total penectomy. The penectomy specimen showed an ulcerated lesion at the glans reaching the cavernous bodies. Microscopic examination showed undifferentiated epithelial cells with syncytial growth pattern mix with a dense lymphoplasmacytic infiltrate, consistent with LELC. The tumor cells expressed p16 and all 3 different clones of PDL1 (22C3, SP263, and SP142). The patient is alive and well with a follow-up of 3 months. To our knowledge, this is the third LELC of the penis reported in literature and the first case reported with PDL1 expression.

ST-elevation myocardial infarction (STEMI) is a rare and potentially fatal complication of infective endocarditis. We report the ninth case of embolic native aortic valve infective endocarditis causing STEMI and the first case to describe consecutive embolisms leading to infarctions of separate coronary territories. Through examination of this case in the context of the previous eight similar documented cases in the past, we find that infective endocarditis of the aortic valve can and frequently affect more than a single myocardial territory and can occur consecutively. Further, current treatment modalities for embolic infective endocarditis causing acute myocardial infarction are limited and unproven. This index case illustrates the potential severity of complications and the challenges in developing standardized management for such patients.

Background: We published the world’s first case of hemi-laryngpharyngeal spasm (HELPS) syndrome cured by microvascular decompression (MVD) of the Xth cranial nerve in 2016. We now present a small cohort of patients (n=3) successfully treated with surgery in order to better delineate the common characteristics of this syndrome, diagnostic tests of choice, nuances of their surgical care and outcomes of their treatment. Methods: The history and physical examination of three patients with HELPS syndrome are presented. Pre-operative laryngoscopy, neuroimaging, response to botox and intra-operative videos are detailed. Post-operative outcome and complications are presented. Results: Each patient reported similar motor (choking) and sensory (coughing) features in their history. Episodic choking relentlessly progressed over the years until it occurred while sleeping and with frightening severity prompting tracheostomy in one patient and intubation in another. A “tickling” sensation deep in the throat triggered episodic coughing that worsened over the years until it occurred while sleeping and with frightening severity (syncope and incontinence). Conclusions: A review of the literature suggests that patients with similar symptoms, often called episodic laryngospasm in the past, have been treated with psychotherapy or antacids. With the recognition that a clearly defined subset of these patients have HELPS syndrome, we can offer them the potential of a neurosurgical cure.

Introduction Chronic granulomatous disease (CGD) is a rare pathology that increases patients’ susceptibility to infections, given the inability to generate oxygen radicals to fight microorganisms. In the context of CGD, primary prostatic involvement has been described only once in the past, in a pediatric patient. Case Report We report the case of a 35-year old patient with CGD presenting with persistent fever. After hospital admission, blood and urine were sent for culture and antibiotic therapy was initiated. Patient's conditions continued to deteriorate and an aggressive antibiotic therapy was administered to treat the septic scenario. Urine culture grew a multidrug-resistant Escherichia Coli. After patient's condition improved, a CT scan was performed. The depiction showed multiple abscesses within the prostate. A rectal approach was excluded given patient's underlying disease. A TURP was performed and prostatic pathology resolved. Patient was discharged on postoperative day 14. At 6-month follow-up he hasn't experienced major infections. To the best of our knowledge, this is the first case of septic shock originating from a prostatic abscess in an adult patient with CGD. Conclusions Aggressive medical therapy along with TURP resulted curative in our case. A multi-disciplinary approach was mandatory.

Entertainment Theory

This chapter aims to differentiate between two kinds of media use experiences that in the past twenty some years have uniformly been labeled entertainment experiences. In the background of four identified fundamental assumptions in entertainment theory (entertainment as reception phenomenon, disparity between what media users want and what they should want, entertainment between approaching and avoiding affective states, entertainment as self-transcendence) media experiences are dichotomized between those that serve users’ hedonic motivations, needs, and interests and others, more fundamental experiences of resonance (which in the recent past have often been labeled eudaimonic) that connect users to the content of a media narrative and ultimately changes them. The argument is made here for communication scholars and media psychologists to refer to entertainment experiences only in the first case in order to be less vague and ambiguous in explicating entertainment theory.

A description of biotechnical methods of harvesting pike perch in natural reservoirs, methods of catching pike perch spawners, keeping in adaptation cages and transporting pike perch from fishing sites to the farm is given. Pike perch breeders were caught from the reservoirs with fixed and floating nets during the period: in the Kapshagai reservoir from 10 to 20 April; in the Syrdarya river — from April 20 to May 5. The adaptation was carried out in cages located in the coastal zone. Transportation to the fish farm was carried out in live fish tanks with a volume of 1 and 3 m³ with water aeration. The reproduction of pike perch was carried out in two fish farms of the Republic of Kazakhstan. The data on spawning of pike perch in two ways are given: in cages on nests; as well as the receipt of reproduction products by the factory method from “flowing” producers. In the first case, females and males were placed in cages in a ratio of 1:1 and 1:2; a spawning nest was installed in each cage and spawning was monitored. In the second case, from the “flowing” pike perch breeders ready for spawning, reproductive products (eggs and sperm) were obtained, fertilization and degluing were carried out with a suspension of white clay. The monitoring of hydrochemical indicators was constantly carried out, the dates of the beginning and end of spawning of pike perch were determined. The article presents the fish-breeding and biological characteristics of pike perch producers participating in spawning. The mass of spawned pike perch females in LLP “Halyk Balyk” ranged from 2 kg to 2.5 kg, males — 1.5–2.5 kg; females weighing 2.1–2.6 kg were used in the Republican State Enterprise “Kamyshly-Bashsky Fish Hatchery”; males — from 1.2 kg to 2.4 kg. Based on the results of the research, biotechnical standards were developed for the preparation of pike perch producers in water bodies, for transportation to fish farms, standards for spawning of pike perch in various ways.

The authors report two cases of Bipolar Affective Disorder which were responsive to Lithium therapy in the past, but could no longer be treated with Lithium due to hyperparathyroidism in the first case and noncompliance in the second. In both cases, successful control of hypomania was achieved with Verapamil, but treatment of depression required the addition of Trazodone. The rationale for employing a calcium channel blocking agent, such as Verapamil, in bipolar illness is reviewed.

O objetivo deste estudo foi analisar a variação da estrutura diamétrica de uma comunidade arbórea em floresta densa de terra firme e dos principais grupos de espécies de estágios iniciais e tardios de sucessão, bem como caracterizar a estrutura vertical da floresta. Em 2016, foram inventariadas todas as árvores com DAP ≥ 10 cm e mensuradas suas alturas. Em 2017, as árvores foram reamostradas. A estrutura diamétrica foi analisada por meio do quociente “q” De Liocourt para: a comunidade, principais espécies de maior VI e os grupos ecológicos (GE). A análise da estrutura vertical da vegetação foi feita pela distribuição do número de árvores nos estratos, utilizando-se três métodos: (I) – Sanquetta (1995), (II) - Souza (1990), e (III) – Souza et al. (2003). A estrutura diamétrica da comunidade e dos GE no período avaliado foi caracterizada por árvores de pequeno porte nas menores classes de diâmetro. O Método II não trouxe bons resultados sobre o comportamento das espécies no estrato médio por apresentar fortes tendências em concentrar um maior número de indivíduos nesse estrato. Os resultados da estrutura altimétrica e diamétrica demonstraram indicativos que a exploração antrópica no passado alterou a estrutura da floresta.Palavras-chave: espécies amazônicas, “q” De Licocourt, estratificação, incremento. STRUCTURE AND DYNAMICS IN A DENSE OF TERRA FIRME FOREST, SOUTHEAST OF AMAPÁ, BRAZIL ABSTRACT:The study aimed to analyze the variation of the diameter structure of a arboreal community in a dense terra firme forest and the main groups of species of early and late stages of succession, as well as characterize the vertical structure of the forest. In 2016, all trees with DBH ≥ 10 cm were inventoried and their heights measured indirectly. In 2017, the trees were re-measured. The diametric structure was analyzed using the "q" De Liocourt quotient for: the community, major species of higher (VI) and ecological groups (EG). The analysis of the vertical structure of the vegetation was made by the distribution of the number of trees in the strata, using three methods: (I) – Sanquetta (1995), (II) - Souza (1990), and (III) – Souza et al. (2003). The diametric structure of the community and the EG during the period evaluated was characterized by small trees in the smallest diameter classes. Method II did not bring good results on the behavior of the species in the middle stratum because it presents strong tendencies to concentrate a greater number of individuals in this stratum. The results of the altimetric and diametric structure have demonstrated that antropic exploration in the past has altered the structure of the forest.Keywords: amazonian species, “q” De Licocourt, stratification, increment.
