Use of morcellation in laparoscopic myomectomy. Medical malpractice and medicolegal considerations.

Background: In recent years, due to the increase in medical mal-practice complaints, the Sicilian Regional Health System has adopted procedures for the direct management of claims by each health facility with the aim of reducing the costs of insurance premiums and related taxes. Mandatory sentinel event monitoring is a crucial part of this strategy to improve patient safety and quality of care. The reported case relates to a laparoscopic myomectomy surgery performed by means of morcellation, a controversial technique. After the FDA's intervention in 2014, it is believed that morcellation may worsen the staging of the disease by spreading malignancies such as leiomyosarcoma into the abdomen. Case report: A 28-year-old woman, underwent laparoscopic surgery for uterine fibroids and an ovarian cyst removal in August 2018. Post-surgery, she was diagnosed with Leiomyoma. She returned to the hospital due to metrorrhagia and was discharged after a week. Persistent symptoms led to her readmission and subsequent exploratory laparoscopic surgery at another hospital. This resulted in a total hysterectomy and the discovery of uterine leiomyosarcoma, with FIGO STAGE IIIB staging. Despite chemotherapy, she passed away six months later. Discussion and Conclusions: This case highlights medical-legal issues. Informed consent for morcellation and its risks was not obtained. The morcellation technique was used, increasing cancer spread risk. The histopathological process was inadequate, with three biopsies leading to misdiagnosis. This could be medical malpractice, making providers legally responsible for the patient's deteriorating condition and the anticipation of possible death.

Entrapment and rupture of the guide wire during PTCA: case report and medico-legal considerations.

Background: In recent years, due to the increase of complaints for medical malpractice, the Sicilian Regional Health System has adopted proceedings for the direct management of claims by each healthcare facility with the aim of reducing costs of insurance premiums and their relative taxes. Thus this management has led to increased awareness and management of clinical risk through the introduction of mandatory sentinel event monitoring. Case report: A 55-year-old man with acute ischemic heart disease, due to three-vasal coronary diasease, underwent angioplasty perfomed on the second diagonal branch of the anterior descending artery. Simultaneously following the discovery of a major middle tract stenosis, he underwent further angioplasty surgery during which guidewire entrapment occurred, precisely in the proximal section of the vessel, resulting in the rupture and persistence of some fragments despite attempts to extract them. Subsequent antiplatelet therapy was prescribed and no further procedures were indicated for the removal of the guide wire, meanwhile a persistent reactive anxious-depressive state was established. Conclusion: The medico-legal analysis of the case excluded liabilty since it was a fortuitous, unpredictable and inevitable event. However, the patient had not been adequately informed about the possibility of the complication presented, which resulted in prolonged hospitalization and compensation for the psychological disorder suffered as a result of the adverse event. The attempted economic agreement was unsuccessful. A civil lawsuit was subsequently filed by the patient and the Judge's report confirmed the corporate CMC assessment and ruled out that the side effects related to the guideline fragment.

MicroRNAs expression in pituitary tumors: differences related to functional status, pathological features, and clinical behavior.

BACKGROUND: MicroRNAs (miRNAs) are small non-coding RNA molecules that regulate gene expression at post-transcriptional level, having a role in many biological processes, such as control of cell proliferation, cell cycle, and cell death. Altered miRNA expression has been reported in many neoplasms, including pituitary adenomas (PAs). PURPOSE: In this study, we aimed to evaluate the expression of 20 miRNAs involved in pathways relevant to pituitary pathophysiology, in PAs and normal pituitary tissue and to correlate their expression profile with clinical and pathological features. METHODS: Pituitary tumor samples were obtained during transphenoidal surgery from patients with non-functioning (NFPA, n = 12) and functioning (n = 11, 5 GH-, 3 ACTH-, 3 PRL-omas) PAs. The expression of selected miRNAs in PAs and in normal pituitary was analyzed by RT-qPCR. miRNAs expression was correlated with demographic, clinical, and neuroradiological data and with histopathological features including pituitary hormones immunostaining, Ki-67 proliferation index, and p53 immunohistochemistry evaluation. RESULTS: All evaluated miRNAs except miR-711 were expressed in both normal and tumor pituitary tissue. Seventeen miRNAs were significantly down-regulated in pituitary tumors compared to normal pituitary. miRNAs were differentially expressed in functioning PAs or in NFPAs, as in the latter group miR-149-3p (p = 0.036), miR-130a-3p (p = 0.014), and miR-370-3p (p = 0.026) were significantly under expressed as compared to functioning tumors. Point-biserial correlation analysis demonstrated a negative correlation between miR-26b-5p and Ki-67 (p = 0.031) and between miR-30a-5p and 'atypical' morphological features (p = 0.038) or cavernous sinus invasion (p = 0.049), while 508-5p was inversely correlated with clinical aggressiveness (p = 0.043). CONCLUSIONS: In this study, we found a significant down-regulation of 17 miRNAs in PAs vs normal pituitary, with differential expression profile related to functional status and tumor aggressiveness.

Polymorphism of glutathione S-transferases M1 and T1: susceptibility to solar keratoses in an Italian population.

BACKGROUND: Polymorphisms of glutathione S-transferases (GSTs) are linked to skin cancer, but data on their association with solar keratosis (SK) are few and conflicting. AIM: To verify the possible association between the development of SK and the 'null' GSTM1 and/or T1 genotype. METHODS: Analysis of the GSTM1 and T1 genotype of 33 subjects with ≥3 solar keratoses and of 150 controls, before and after stratification based on smoking habits, sun exposure and immunosuppression. RESULTS: The GST T1 null allele is significantly (P < 0.03) associated with increased prevalence of SK in our population. CONCLUSIONS: Our study, the first on a Mediterranean population, shows the existence of a correlation between SK and the GST T1 null genotype. This result points out significant differences between subjects of different ethnic and geographical origin and warrants further investigation on a larger population, and ethnically different populations.

[2 fatal cases of acute myeloid leukemia (M3, M4) during pregnancy]. / Su due casi mortali di leucemia mieloide acuta in gravidanza (M3, M4).

Two cases of unexpected post-partum death of women with acute leukemia are described. In the first case (1st pregnancy) the diagnosis (acute promyelocytic leukemia: M3) was performed one week before delivery and death occurred 3 days later, because of hemorrhagic and renal DIC complication. Since one month before hospitalization, laboratory exams indicated a serious hematological pathology and no further exams were carried out by the physicians, elements of professional fault were recognized in them, considering that because of the diagnostic omission it was impossible to make an early diagnosis and thus perform to specific therapy, adopted only in the terminal phase. This specific therapy is able to determine remission from most cases of acute promyelocytic leukemia. In the second case (2nd pregnancy) the diagnosis (acute myelomonocytic leukemia: M4) was performed only postmortem because, during the whole pregnancy, no signs of disease were evident. After a few hours from the spontaneous delivery, death occurred as a result of an intractable + hemorrhagic syndrome caused by primary hyperfibrinolysis and repeated episodes of cardiac arrest, without possibility of recognizing it. The medical procedures for this case, both throughout pregnancy and terminal phases, appeared free of censure.
