Experimental proof pertaining to neonicotinoid driven decline in water rising bugs.
The aim of this work was characterization of airborne particulates in the port city of Rijeka in order to evaluate impact of ship emissions on air quality. Samples of airborne particulates were collected with a ten stages cascade impactor during two campaigns autumn and spring. A total of 16 weekly samples were analyzed on mass concentration, ions, metals and carbonaceous species (EC, OC, WSOC). Distribution of airborne fractions showed a bimodal distribution, with two maxima one in coarse, and other in fine fraction. Source apportionment using PMF receptor model identified six sources of airborne particulates in Rijeka crustal, biomass burning, sea salt, traffic/metal industry, combustion/SIA and HFO burning, i.e., ship emission (contribution 3%). The contribution of ship traffic to primary emission of particulate matter, using vanadium as tracer, indicated a twofold increase for PM10 and PM2.5 relative to 2012-14. An unusual desert dust event was registered in autumn campaign.In intertidal areas, oyster farming creates a crosshatching pattern between oyster tables and aisles. Tables provide a refuge from the current and solar irradiance and the oysters facilitate the accumulation of OM, thereby structuring the spatial organization of the associated macrozoobenthic community at mesoscale. The aim of this study was to describe the quality of the oyster table environment at small scale and the response of the macrozoobenthic community to OsHV-1 μvar oyster mortality. The species assemblage was dominated by Golfingia vulgaris, Tubificoides benedii, Capitella capitata and Scoloplos armiger. The table habitat appeared to be in a bad ecological state throughout the 2-month survey (May and June 2017), whereas in the aisle, eutrophication occurred lately and was clearly related to be due to the massive stranding of dead seaweed at the end of the survey (in early July). So, this disturbance of the species assemblage seemed to occur in two phases 1) after oyster spat mortality and 2) after seaweed stranding resulted in a bad ecological status, as revealed by macrofaunal indicators. Large quantities of OsHV-1 DNA were also found in some species, including small crabs and amphipods, one week after the mortality crisis, but there is no apparent virus reservoir found in the benthic species.The sink-source controversy for global polycyclic aromatic hydrocarbons (PAHs) in high-latitude seas is extremely concerning. A level III fugacity model was developed for the southern Chukchi Sea to estimate the fate of 16 priority PAHs. The model results indicate large losses were due to seawater advection outflow, followed by degradation in seawater. The Chukchi Sea serves as a source of 4 PAHs (i.e., Nap, Ace, Acp and Fl) in the atmosphere and sediment but acts as a final sink for the other 12 PAHs. The water-air diffusion flux and wet deposition flux play dominant roles in the total transfer flux of the 4 PAHs and the other 12 PAHs, respectively. The source/sink role that high-latitude seas play in PAH distribution has changed under the influence of global climate change. The model proposed in this study provides an approach to support further study of the fate of PAHs in high-latitude seas.
SARS CoV19 infection can predispose to many autoimmune and neurological conditions, thymomatous myasthenia gravis being one of them. The rarity of these case poses therapeutic dilemmas about their further management.

A 61 year old gentleman who had covid19 infection 2 months back, presented with new onset myasthenia gravis and an anterior mediastinal mass. He was diagnosed as a case of anti acetyl choline receptor antibody positive thymomatous myasthenia gravis. The patient was posted for video assisted thoracoscopic excision of thymoma. The procedure was uneventful and patient was discharged with improvement in myasthenic symptoms. Histopathological examination confirmed the diagnosis of WHO Type A Spindle cell thymoma.

SARS CoV19 infection is associated with an array of autoimmune disorders due to various proposed phenomenon including molecular mimicry and loss of immune tolerance. Post infectious thymomatous myasthenia gravis is extremely uncommon, and can be managed with open, minimally invasive or robotic approach.

This is the first documented case of post covid19 infection thymomatous myasthenia gravis to the best of our knowledge, managed with minimally invasive thoracoscopic surgery. Further research is required for documentation of the natural history of the disease and therapeutic outcomes.

Spontaneous urinary bladder rupture is a rare complication of urosepsis. Its co-occurrence with pneumoperitoneum is even more unusual.

A 73-year-old patient presented with acute retention with mild lower abdominal pain and difficulty with urinary voiding and cystitis. He was treated with bladder catheter and antibiotics. After one month, he suddenly developed peritonitis and shock. Pneumoperitoneum was observed on a chest x-ray. An emergent laparotomy was performed and a perforation of the bladder secondary to necrosis of part of the wall was found and resected. The patient recovered satisfactorily after the surgical intervention.

Spontaneous bladder rupture is a life-threatening condition that could be missed. IAP antagonist Surgical intervention is mandatory to rule out other more probable causes of peritonitis and to manage the bladder perforation itself.

Pneumoperitoneum is rarely secondary to a bladder perforation. Immediate surgical intervention is required in order to avoid delays in treating any intra-abdominal condition including a bladder wall perforation.

Schwannomas are benign tumors of the nerve sheath, they do not typically present on the abdominal wall and cause symptoms. To the best of our knowledge, this is the second symptomatic case of schwannoma in upper abdominal wall reported according to the reviewed English medical literature.

A 25-year-old man post renal transplant two year ago. He presented with left hypochondrial painfull swelling, and redness. On examination, local examination revealed a lesion located in the anterior abdominal wall swelling, 3 × 3 cm, tender with minimal erythema and hotness but no discharge. An ultrasound showed superficial oval shaped with thick wall and mildly increased peripheral vascularity without internal vascularity. He underwent surgical excision and the histopathology result was schwannoma.

Usually, a patient presents asymptomatic with a slow growing mass. However, the symptoms can vary and depending on the location. Furthermore, a growing lump can start putting pressure on the nerves around the area, and patients can show symptoms accordingly.
