Influences of salinity on the physiology and distribution of the Arctic coralline algae, Lithothamnion glaciale (Corallinales, Rhodophyta)

In Greenland, free-living red coralline algae contribute to and dominate marine habitats along the coastline. Lithothamnion glaciale dominates coralline algae beds in many regions of the Arctic, but never in Godthåbsfjord, Greenland, where Clathromorphum sp. is dominant. To investigate environmental impacts on coralline algae distribution, calcification and primary productivity were measured in situ during summers of 2015 and 2016, and annual patterns of productivity in L. glaciale were monitored in laboratory-based mesocosm experiments where temperature and salinity were manipulated to mimic high glacial melt. The results of field and cold-room measurements indicate that both L. glaciale and Clathromorphum sp. had low calcification and photosynthetic rates during the Greenland summer (2015 and 2016), with maximum of 1.225 ± 0.17 or 0.002 ± 0.023 μmol CaCO3 · g-1 · h-1 and -0.007 ±0.003 or -0.004 ± 0.001 mg O2 · L-1 · h-1 in each species respectively. Mesocosm experiments indicate L. glaciale is a seasonal responder; photosynthetic and calcification rates increase with annual light cycles. Furthermore, metabolic processes in L. glaciale were negatively influenced by low salinity; positive growth rates only occurred in marine treatments where individuals accumulated an average of 1.85 ± 1.73 mg · d-1 of biomass through summer. These results indicate high freshwater input to the Godthåbsfjord region may drive the low abundance of L. glaciale, and could decrease species distribution as climate change increases freshwater input to the Arctic marine system via enhanced ice sheet runoff and glacier calving.Peer reviewedFinal Accepted Versio

Bladder colloid carcinoma: A case report

Non-urothelial bladder cancers are rare. We report the case of a 72-year-old who consulted for terminal hematuria evolving for three months. Computed Tomography scan showed a tumor of the anterior wall of the bladder. The patient underwent a transurethral resection of the bladder tumor. The histological examination of the tumor showed a bladder colloid carcinoma. The extension evaluation showed pulmonary and bone metastases. The patient received chemotherapy

Pancreatic pseudocyst mimicking a left kidney abscess: a case report

Abstract Background Pancreatic pseudocyst are fluid filled sacs that develop as a result of dissection of pancreatic enzyme tissue. While most commonly found near the pancreas, they can also rarely occur in other areas such as the perirenal region. Case presentation This study reports a new case of an infected perirenal pancreatic pseudocyst mimicking a left kidney abscess in a 46-year-old North African patient with history of recurrent acute pancreatitis, who presented with left lumbar region pain and fever. Computed tomography revealed a left perirenal collection that turned out to be an infected pancreatic pseudocyst, The diagnostic was first suspected based on the medical history of the patient and confirmed by biochemical examination detecting a high level of pancreatic enzymes in the computed tomography-guided percutaneous drainage fluid. The patient evolved well after early resuscitation, rapid and effective antibiotic therapy, and computed tomography-guided percutaneous drainage of renal collection. Conclusion Pancreatic pseudocyst is an uncommon disorder, which may present at a complicated stage and that must be considered in patients with a history of pancreatitis

Intrascrotal self insertion of foreign body: Form of entry to schizophrenia

A 23-year-old boy was referred to Urology because of a nail self insertion on the scrotum. Examination revealed a visible big nail within the scrotum, lateralized to the right at 1 cm from the median raphe. Scrotal exploration and debridement of non-viable tissue was performed, and no testicular or surrounding structure injury was found. Referred to a psychiatrist the diagnosis of schizophrenia was retained in our patient in front of several arguments including the self-mutilation and his psychiatrist concluded that this was secondary to delusions

Massive hydronephrosis due to obstruction by upper urinary tract urothelial carcinoma with compression of the inferior vena cava

A 78-year-old woman presented with tachypnea, abdominal distension, bilateral lower limb edema, and hematuria. A contrast-enhanced CT scan of the abdomen and pelvis was performed, which revealed a significant left-sided hydronephrosis upstream of an upper urinary tract urothelial carcinoma (UUT-UC). The patient underwent a left open nephroureterectomy, and approximately 10 L of fluid were evacuated. Follow-up examinations did not show any recurrence of abdominal swelling

Ocular abscess: An extremely rare complication of transurethral resection of the prostate

Ocular abscess following transurethral resection of the prostate is an rare complication. We report the case of a male who developed an ocular abscess with purulent melting of the eye after undergoing TURP for benign prostatic hyperplasia. The patient successfully underwent the TURP procedure. However, he developed a right epididymitis and subsequently an ocular abscess on the same side. Treatment involved dual antibiotic therapy for the epididymitis, followed by incision of the ocular abscess and intravenous antibiotics. Multidrug-resistant Escherichia coli was identified in both ocular and postoperative urine cultures. This case highlights the rarity and potential serious complications following TURP
