Conversion of Fischer-Tropsch wax into high quality synthetic crude or finished transportation fuels such as premium diesel has been studied over the past 15 years within BP. Catalyst screening and selection was carried out in dedicated micro-reactors and pilot plants, whose designs are critical to the performance selection. Variation in catalyst composition and defining the gas to oil feed ratios with the operating temperature are a few of the parameters studied. Product selection and maximizing diesel yield combined with stability （catalyst life） were the ultimate drivers. The selected catalyst was then tested under commercial conditions in a dedicated 300 barrel per day demonstration plant. The products were also tested in engines to assess their combustion characteristics.

BACKGROUND： Ectopic pancreatic tissue is relatively uncommon, and is characterized as pancreatic tissue with no contact with the normal pancreas, and with its own ductal system and blood supply. It is usually asymptomatic, and can be incidentally diagnosed by conventional imaging studies. METHOD： A 69-year-old woman with a prior history of bilateral breast carcinoma presented with ectopic pancreatic intraepithelial neoplasia （PanIN） that was identified incidentally in the small bowel during an oncological resection of a synchronous primary pancreatic adenocarcinoma, and renal cell carcinoma. RESULTS： The patient underwent subtotal pancreatectomy with splenectomy, regional lymphadenectomy, radical left nephrectomy, and small bowel resection with primary anastomosis of ectopic PanlN-2. She had an uneventful hospitalization and was discharged home on postoperative day 7. CONCLUSIONS： The occurrence of ectopic PanIN is extremely unusual with only few cases previously reported in the literature. The need for negative margins after surgical resection of ectopic PanIN lesions remains controversial.

The aim is to highlight the epidemiological, clinical and therapeutic aspects of iatrogenic urethral strictures. Methodology: This was a retrospective study, descriptive type, 6 years from January 1st 2012, to December 31st 2017 carried out in the Urology-Andrology department of the National Hospital Ignace Deen of Conakry. All records of patients carrying the Diagnosis of iatrogenic urethral stricture were included in this study. Results: We collected 30 cases of iatrogenic urethral stricture, with a frequency of 2.5%. The average age of the patients was 62.33 years. The most affected age group is from 71 to 80 years (33.33%). Dysuria was the main reason for consultation. Retrograde urethrocystography plus voiding cystourethrography (RUC-VCU) allowed us to make the diagnosis. The treatment was essentially surgical and several techniques were used. Endoscopic internal urethrotomy alone was the most performed surgical technique, followed by segmental uretrectomy associated with end-to-end urethrography. Conclusion: Iatrogenic urethral stricture is easy to diagnose but difficult to manage due to the frequency of recurrences. Improving the quality of care, in particular urethral catheterizations and transurethral endoscopic maneuvers, makes it possible to prevent it.

Background and Aim: Ecthyma gangrenosum (EG) is a rare necrotic skin infection caused by Pseudomonas aeruginosa occurring on healthy skin mainly, but not exclusively, in immunocompromised patients. We report the case of EG of unusual presentation in a 12-month-old infant. Case Presentation: This was a 12-month-old male infant who was referred from a peripheral structure for the treatment of facial swelling associated with fever. In his antenatal and intra nasal history, there was a notion of hospitalization for 15 days for early neonatal infection and a delay in psychomotor development. The admission examination showed the fair general condition, hyperthermia at 39°C, tachycardia at 136 beats/minute, and polypnea at 48 cycles/minute. The weight-for-height index with a z-score of 3DS was also found. The dermatological examination at the entrance found an extensive brownish inflammatory tense infiltrated plaque taking the mandibular, submental, retro-auricular occipital regions rapidly evolving towards necrosis, a significant swelling predominant on the upper right eyelid preventing the opening of the associated eyes to mouth ulceration. Biological abnormalities were predominantly neutrophilic leukocytosis, elevated CRP, and elevated muscle enzymes. Microbiological examination of skin samples had isolated Pseudomonas aeruginosa. He had received antibiotic therapy, and a necrosectomy under general anesthesia. The evolution was favorable and he was discharged from the hospital on D26 of hospitalization. Conclusion: This observation is rare due to its location, its early onset, and non-neutropenic background.
