Acute Q Fever Presenting with Multi-Organ Failure: Re-Evaluation of the Initial Diagnosis

We present the case of a 48-year-old man admitted to the critical care unit with atrial fibrillation, and acute heart and kidney failure accompanied by coagulopathy and an abnormal liver test. Initially diagnosed as a non-ST elevation myocardial infarction, re-evaluation of the case led to the consideration of severe sepsis. Q fever and leptospirosis were the most probable causes and empiric treatment was initiated. A complete recovery was achieved following treatment.

Technique and outcomes about a new laparoscopic procedure: the Pelvic Organ Prolapse Suspension (POPS)

Pelvic organ prolapse suspension (POPS) is a recent surgical procedure for one-stage treatment of multiorgan female pelvic prolapse. This study evaluates the preliminary results of laparoscopic POPS in 54 women with a mean age of 55.2 and a BMI of 28.3. Patients underwent at the same time stapled transanal rectal resection (STARR) to correct the residual rectal prolapse. We had no relapses and the preliminary results were excellent. We evaluated the patients after 1 year follow-up and we confirmed the validity of our treatment. The technique is simplier than traditional treatments with an important reduction or completely disappearance of the pre-operative symptomatology.

Biomimetic Scaffold with Aligned Microporosity Designed for Dentin Regeneration

Tooth loss is a common result of a variety of oral diseases due to physiological causes, trauma, genetic disorders, and aging and can lead to physical and mental suffering that markedly lowers the individual’s quality of life. Tooth is a complex organ that is composed of mineralized tissues and soft connective tissues. Dentin is the most voluminous tissue of the tooth and its formation (dentinogenesis) is a highly regulated process displaying several similarities with osteogenesis. In this study, gelatin, thermally denatured collagen, was used as a promising low-cost material to develop scaffolds for hard tissue engineering. We synthetized dentin-like scaffolds using gelatin biomineralized with magnesium-doped hydroxyapatite and blended it with alginate. With a controlled freeze-drying process and alginate cross-linking, it is possible to obtain scaffolds with microscopic aligned channels suitable for tissue engineering. 3D cell culture with mesenchymal stem cells showed the promising properties of the new scaffolds for tooth regeneration. In detail, the chemical–physical features of the scaffolds, mimicking those of natural tissue, facilitate the cell adhesion, and the porosity is suitable for long-term cell colonization and fine cell–material interactions.

Severe Case of Thrombotic Microangiopathy with a Delayed Diagnosis of Atypical Haemolytic Uraemic Syndrome Successfully Managed with Eculizumab

Objectives: To describe the diagnosis and treatment of a severely ill patient presenting with thrombotic microangiopathy (TMA) of unknown cause. Case presentation: An adult female presented to intensive care with abdominal pain and haemorrhagic shock, requiring reanimation. Results: Features of TMA were present, but initial plasma exchange was ineffective. Treatment with the anti-C5 antibody, eculizumab, improved laboratory parameters and organ function, albeit slowly. Eculizumab remains effective and well tolerated after 30 months of treatment. Conclusion: This case demonstrates the complexities and importance of early identification of atypical haemolytic uraemic syndrome in patients presenting with TMA.

Brucella Non-Neutrocytic Bacterascites in a Patient with Chronic Liver Disease

Objectives: To report a case of Brucella peritonitis. Patient and methods: We describe the case of a patient and present a brief review of the few published reports. Results: The patient had alcoholic cirrhosis of the liver and was diagnosed with Brucella non-neutrocytic bacterascites. Conclusion: Brucellosis is a common zoonosis with worldwide distribution. It is a systemic disease with the potential to predominantly affect one organ or a specific system (focal brucellosis). However, peritoneal focalization of this disease is a very rare presentation.
