Solitary fibrous tumour of the liver with IGF-II-related hypoglycaemia. A case report.

IntroductionWe report a rare case of solitary fibrous tumour (SFT) of the liver associated with non-islet cell tumour hypoglycaemia (NICTH), which caused a hypoglycaemic coma due to over-production of big-insulin-like growth factor-II.DiscussionAlthough generally benign, SFTs are better characterised, lately due to Western blot, but less than 40 cases have been reported where the liver is the target organ. In only two benign cases has hypoglycaemia been a feature.ConclusionWe report for the first time a demonstrable relationship between benign liver SFT and NICTH.

Cancer Cachexia Syndrome: Pathogenesis, Diagnosis, and New Therapeutic Options

Cancer anorexia-cachexia syndrome (CACS) is the most frequent paraneoplastic syndrome occurring in half of all oncologic patients and is considered as a poor prognosticator. Patients usually present with weight loss, lipolysis, muscle wasting, anorexia, chronic nausea, inflammation, and asthenia. The etiopathogenesis of CACS is still poorly understood, although several factors and biological pathways are known to be involved. Because of the complexity of this multifactorial condition, a single agent therapy may not be sufficient. Indeed, there is a tendency toward an integrated multiple approach including nonpharmacological and pharmacological treatments. However, despite encouraging preliminary results, currently there is not enough evidence to support a change in clinical practice. This review provides a brief and practical summary of the diagnosis, pathogenesis, and treatment of CACS. Future perspectives will also be discussed.

Lack of the Nlrp3 Inflammasome Improves Mice Recovery Following Traumatic Brain Injury

Treatment for traumatic brain injury (TBI) remains elusive despite compelling evidence from animal models for a variety of therapeutic targets. The activation of the NLRP3 (Nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3) inflammasome has been proposed as key point in the brain damage associated with TBI. NLRP3 was tested as potential target for reducing neuronal loss and promoting functional recovery in a mouse model of TBI. Male NLRP3-/- (n = 20) and wild type (n = 27) mice were used. A closed TBI model was performed and inflammatory and apoptotic markers were evaluated. A group of WT mice also received BAY 11-7082, a NLRP3 inhibitor, to further evaluate the role of this pathway. At 24 h following TBI NLRP3-/- animals demonstrated a preserved cognitive function as compared to WT mice, additionally brain damage was less severe and the inflammatory mediators were reduced in brain lysates. The administration of BAY 11-7082 in WT animals subjected to TBI produced overlapping results. At day 7 histology revealed a more conserved brain structure with reduced damage in TBI NLRP3-/- animals compared to WT. Our data indicate that the NLRP3 pathway might be exploited as molecular target for the short-term sequelae of TBI.

Early experience with laparoscopic major liver resections: a case-comparison study.

Laparoscopic major liver resections are regarded as demanding operations whose convenience is still under evaluation. The aim of the present study was to report our early experience and to describe surgical technique of laparoscopic major liver resections. Study group consisted of 6 female patients with benign disease and a mean age of 40.5 years, who underwent right hepatectomy in 4 cases and left hepatectomy in 2 cases. No mortality was observed. Morbidity consists in 1 biliary fistula that requires rehospitalization and a new laparoscopic operation. The mean operative time was of 201.7 minutes, with a mean hospital stay of 5.5 days. The authors conclude that laparoscopic major liver resections could be performed, at least for benign disease and by surgeons experienced in laparoscopy, with good results. Nevertheless, further studies are required before to draw definitive conclusions, especially for neoplastic patients who represent the most relevant group.

An update on anesthetics and impact on the brain

ABSTRACT Introduction: While anesthetics are indispensable clinical tools and generally considered safe and effective, a growing concern over the potential neurotoxicity of anesthesia or specific anesthetic agents has called into question the safety of general anesthetics, especially when administered at extremes of age. Areas covered: This article reviews and updates research findings on the safety of anesthesia and anesthetics in terms of long-term neurotoxicity, with particular focus on postoperative cognitive dysfunctions, Alzheimer’s disease and dementias, developing brain, post-operative depression and autism spectrum disorder. Expert opinion: Exposure to general anesthetics is potentially harmful to the human brain, and the consequent long-term cognitive deficits should be classified as an iatrogenic pathology, and considered a public health problem. The fact that in laboratory and clinical research only certain anesthetic agents and techniques, but not others, appear to be involved, raises the problem on what is the safest and the least safe anesthetic to maximize anesthesia efficiency, avoid occurrence of adverse events, and ensure patient safety. New trends in research are moving toward the theory that neuroinflammation could be the hallmark of, or could have a pivotal role in, several neurological disorders.

Lymph Node Metastasis From Gastric Carcinoid Tumors Occurring Concomitantly With Gastric Adenocarcinomas and Atrophic Gastritis

Abstractdescribe a case of gastric carcinoids concomitant with gastric adenocarcinoma in a 50-year-old woman affected by atrophic gastritis. Number and size of the lesions, pathological examinations, and un-derlying gastric disease all indicated low-risk carcinoids. Nevertheless, when R1 gastrectomy was carried out, an unsuspected lymph node metastasis from carcinoid was found along the lesser curvature. The same occurrence is reported in several cases of the literature, which suggests that the association of gas-tric carcinoid to adenocarcinoma could point to the malignant nature of carcinoid, apart from underlying gastric disease and tumor characteristics.

Facial Bone Reconstruction Using both Marine or Non-Marine Bone Substitutes: Evaluation of Current Outcomes in a Systematic Literature Review

The aim of the present investigation was to systematically analyse the literature on the facial bone reconstruction defect using marine collagen or not and to evaluate a predictable treatment for their clinical management. The revision has been performed by searched MEDLINE and EMBASE databases from 2007 to 2017. Clinical trials and animal in vitro studies that had reported the application of bone substitutes or not for bone reconstruction defect and using marine collagen or other bone substitute material were recorded following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The first selection involved 1201 citations. After screening and evaluation of suitability, 39 articles were added at the revision process. Numerous discrepancies among the papers about bone defects morphology, surgical protocols, and selection of biomaterials were found. All selected manuscripts considered the final clinical success after the facial bone reconstruction applying bone substitutes. However, the scientific evidence regarding the vantage of the appliance of a biomaterial versus autologous bone still remains debated. Marine collagen seems to favor the dimensional stability of the graft and it could be an excellent carrier for growth factors.

An unusual presentation of secondary involvement of B-cell chronic lymphocytic leukemia. A case report.

Extramammary tumors rarely metastasize to the breast. The commonest tumors to metastasize in breast tissue are lymphoproliferative diseases, melanoma, lung cancer and gynecological malignancies. Primary breast lymphoma has been reported in the literature with a maximum percentage of about 0.5% of all breast malignancies, while secondary localizations of lymphomas in the breast are less well studied in the literature than primary ones. The authors report a rare case of a secondary localization of B-cell chronic lymphocytic leukemia to the breast in which the diagnosis was obtained by histopathology and immunohistochemistry and further confirmed by molecular data. This occurrence must be considered in the differential diagnosis of a breast lump so that the primary hematological disease can be adequately treated and the correct type of breast surgery performed.

Nonfatal Cervical-Neck Lesion With a Wooden Foreign Body: Diagnosis and Management.

Penetrating cervical lesions caused by a foreign body are rare events. The neck is a complex and delicate body region, given the important vascular structures it holds. The most frequent fatal complications often involve vascular injuries, and as a consequence, the mortality rate increases by approximately 50%. Civilian patients are mainly victims of violence or motor vehicle accidents and rural accidents involving neck are not very common. When a cervical lesion is because of a wooden foreign body, infectious risk increases for its organic peculiarity. The authors report a rural nonfatal cervical lesion in a civilian, and its management.
