We report a case of CMV (cytomegalovirus) infection in a Crohn's disease patient, resulting in severe hemophagocytic syndrome and death. A 63-year-old man with a 10-year history of ileal and colonic Crohn's disease presented with general malaise, loss of appetite and weight loss over the last month. He was in clinical remission for two years, with maintenance therapy 5-Aminosalicylic acid (5-ASA)-derived Mesalamine. The patient had no prior immunomodulators or suppressive treatment. A colonoscopy was performed and we found appearance suggestive of active Crohn's disease, confirmed by histopathological examination. A diagnosis of an exacerbation of Crohn's disease was established. Although the specific treatment was initiated, patient's general condition degraded progressively and diarrheal stools appeared, followed by an episode of massive gastrointestinal bleeding - hematochezia. We performed a new colonoscopy and the pathological examination revealed Crohn's ileocolitis with superimposed CMV infection. Despite the initiation of Ganciclovir alongside with other intensive care measures, he increasingly deteriorated and chest X-ray confirmed multilobar pneumonia. The occurrence of rapidly progressing pancytopenia and evidence for disseminated intravascular coagulopathy as well as hyperferritinemia, raised the suspicion of hemophagocytic syndrome confirmed by bone marrow aspiration. Hence, CMV-associated hemophagocytic syndrome in the context of recent corticotherapy for Crohn's disease was established. There is enough evidence that supports the gravity of the CMV infection in the case of inflammatory bowel disease (IBD) patients, especially the ones on immunomodulator treatment. The hemophagocytic syndrome reactively occurs in patients with infections in cases of immunodeficiency, displaying a hematological aspect of multiple organ dysfunction syndrome.

Tuberculosis (TB) of the tongue is not a common finding diagnosis, even if consider endemic areas. Tuberculosis of the tongue sometimes can mimic lingual neoplasm. Oral tuberculosis is rarely primary as mechanism, and frequently secondary to pulmonary tuberculosis. There are many suspect lesions that can be classified as tuberculosis, such as tumor mass, ulcerative lesion or fissure. It is very important for diagnosis to perform histopathological examination of the biopsy. We present here the case of a 74-year-old man who developed lingual tuberculosis with a tumor aspect concomitant with pulmonary tuberculosis. Histopathological and immunohistochemical examinations established the diagnosis of lingual tuberculosis.

Here we report a newly synthesized vectorizing nanosystem, based on hydrodispersible magnetite nanoparticles (HMNPs) with an average size less than 10 nm, obtained by precipitation of Fe(II) and Fe(III) in basic solution of p-aminobenzoic acid (PABA), characterized by high-resolution transmission electron microscopy (HR-TEM), dynamic light scattering (DLS), X-ray diffraction (XRD), differential thermal analysis coupled with thermogravimetric analysis (DTA-TGA) and bioevaluated for cytotoxicity and antibiotic delivery in active forms. The obtained data demonstrate that HMNPs can be used as an efficient drug delivery system, for clinically relevant antimicrobial drugs. HMNPs antimicrobial activity depended on the loaded drug structure and the tested microbial strain, being more efficient against Pseudomonas aeruginosa, comparing with the Escherichia coli strain. The novel HMNPs demonstrated an acceptable biocompatibility level, being thus a very good candidate for biomedical applications, such as drug delivery or targeting.

This paper describes a case of thoracic endometriosis in 36-year-old woman with a long delay in diagnosis. At the admission in the hospital, the patient had a medical history of persistent dysmenorrhea since the age of 13, infertility and an episode of total right pneumothorax two months ago successfully resolved by minimum pleurotomy of the right hemitorax. She came with moderate pain on right hemithorax and dyspnea, which occurred on the first day of menstruation but she did not have any other respiratory symptoms such as hemoptysis, cough. Radiological imaging (chest radiography and computer tomography) at the time of admission confirmed recurrence of the right pneumothorax. She underwent surgical treatment of the right pneumothorax using a single-port video-assisted approach. Intraoperative macroscopic lesions were found catamenial pneumothorax characteristic diagnosis and biopsy material taken (parietal pleura) for histopathology. Immuno-histochemical tests confirmed the diagnosis of thoracic endometriosis. The gonadotropin-releasing hormone analogue was received by the patient early after surgery and there was no clinical or radiological recurrence at a four months follow-up.
