The gut microbiome as possible mediator of the beneficial effects of very low calorie ketogenic diet on type 2 diabetes and obesity: a narrative review.

Several studies have shown a strong correlation between the different types of diets and gut microbiota composition on glycemia and weight loss. In this direction, low-carbohydrate and ketogenic diets have gained popularity, despite studies published so far leading to controversial results on subjects with diabetes. In this narrative review, firstly, we aimed to analyze the role of very-low-calorie ketogenic diets (VLCKDs) in type 2 diabetes (T2DM) and obesity management. Secondly, in this context, we focused attention on gut microbiota as a function of VLCKD, particularly in T2DM and obesity treatment. Finally, we reported all this evidence to underline the importance of gut microbiota to exalt new nutritional strategies for "tailor-made" management, treatment, and rehabilitation in subjects with T2DM and obesity, even with diabetic complications. In conclusion, this narrative review outlined the beneficial impact of VLCKD on gut microbiota even in subjects with T2DM and obesity, and, despite inner VLCKD short-duration feature allowing no sound-enough provisions for long-term outcomes, witnessed in favor of the short-term safety of VLCKD in those patients.Level of evidence Level V: Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Third-trimester ultrasound for antenatal diagnosis of placenta accreta spectrum in women with placenta previa: results from the ADoPAD study.

OBJECTIVE: To evaluate the performance of third-trimester ultrasound for the diagnosis of clinically significant placenta accreta spectrum disorder (PAS) in women with low-lying placenta or placenta previa. METHODS: This was a prospective multicenter study of pregnant women aged ≥ 18 years who were diagnosed with low-lying placenta (< 20 mm from the internal cervical os) or placenta previa (covering the internal cervical os) on ultrasound at ≥ 26 + 0 weeks' gestation, between October 2014 and January 2019. Ultrasound suspicion of PAS was raised in the presence of at least one of these signs on grayscale ultrasound: (1) obliteration of the hypoechogenic space between the uterus and the placenta; (2) interruption of the hyperechogenic interface between the uterine serosa and the bladder wall; (3) abnormal placental lacunae. Histopathological examinations were performed according to a predefined protocol, with pathologists blinded to the ultrasound findings. To assess the ability of ultrasound to detect clinically significant PAS, a composite outcome comprising the need for active management at delivery and histopathological confirmation of PAS was considered the reference standard. PAS was considered to be clinically significant if, in addition to histological confirmation, at least one of these procedures was carried out after delivery: use of hemostatic intrauterine balloon, compressive uterine suture, peripartum hysterectomy, uterine/hypogastric artery ligation or uterine artery embolization. The diagnostic performance of each ultrasound sign for clinically significant PAS was evaluated in all women and in the subgroup who had at least one previous Cesarean section and anterior placenta. Post-test probability was assessed using Fagan nomograms. RESULTS: A total of 568 women underwent transabdominal and transvaginal ultrasound examinations during the study period. Of these, 95 delivered in local hospitals, and placental pathology according to the study protocol was therefore not available. Among the 473 women for whom placental pathology was available, clinically significant PAS was diagnosed in 99 (21%), comprising 36 cases of placenta accreta, 19 of placenta increta and 44 of placenta percreta. The median gestational age at the time of ultrasound assessment was 31.4 (interquartile range, 28.6-34.4) weeks. A normal hypoechogenic space between the uterus and the placenta reduced the post-test probability of clinically significant PAS from 21% to 5% in women with low-lying placenta or placenta previa in the third trimester of pregnancy and from 62% to 9% in the subgroup with previous Cesarean section and anterior placenta. The absence of placental lacunae reduced the post-test probability of clinically significant PAS from 21% to 9% in women with low-lying placenta or placenta previa in the third trimester of pregnancy and from 62% to 36% in the subgroup with previous Cesarean section and anterior placenta. When abnormal placental lacunae were seen on ultrasound, the post-test probability of clinically significant PAS increased from 21% to 59% in the whole cohort and from 62% to 78% in the subgroup with previous Cesarean section and anterior placenta. An interrupted hyperechogenic interface between the uterine serosa and bladder wall increased the post-test probability for clinically significant PAS from 21% to 85% in women with low-lying placenta or placenta previa and from 62% to 88% in the subgroup with previous Cesarean section and anterior placenta. When all three sonographic markers were present, the post-test probability for clinically significant PAS increased from 21% to 89% in the whole cohort and from 62% to 92% in the subgroup with previous Cesarean section and anterior placenta. CONCLUSIONS: Grayscale ultrasound has good diagnostic performance to identify pregnancies at low risk of PAS in a high-risk population of women with low-lying placenta or placenta previa. Ultrasound may be safely used to guide management decisions and concentrate resources on patients with higher risk of clinically significant PAS. © 2022 The Authors.

The evaluation of skin lesions, according to the Toven Method - an interprofessional communication tool.

BACKGROUND: In the wound care field, effective communication within the interdisciplinary staff is essential and the use of tools that foster it is important. The use of a common language among professionals in the assessment and monitoring process, along with documentation of the outcome, avoids the useless repetition of performances by professionals, with a considerable save of time. OBJECTIVE: One year after its publication, we wanted to evaluate the effectiveness of the Toven Evaluation Form as an interdisciplinary communication tool, for the assessment of cutaneous lesions, according to the Toven Method. MATERIAL: The instrument got under observation also allows the graphic recording of the characteristics of the skin lesions (size, wound conditions, undermining and perilesional skin) according to specific pre-established rules, in an easy and intuitive way for the evaluator and the rest of the multidisciplinary team. It is an integral part of the Toven File. An anonymous, specially created questionnaire containing 20 questions was used for its evaluation. METHODS: A fact-finding inquiry was initiated by recruiting a multidisciplinary sample of 101 professionals who managed skin lesions in their activity. Before completing the form, all the participants attended a two-hour training course, which took place through a lecture and a practical session. RESULTS: Sample composition: 76.2% females, 23.8% males; 63.4% nurses, 10.9% Wound Care Specialist nurses; 16,8% doctors; 8.9% physiotherapists. Of these, 69.3% had work experience >5 years. The technical quality of the instrument was considered excellent by 83.2% of professionals and good by 16.8% of them. The data recorded with the aid of the instrument were considered complete by 100% of the sample. Furthermore, 99% of the sample interviewed declared that the tool is easy to use and would be interested in including it in daily practice; 100% declares that the use of the form can facilitate its work, which can be easily understood and used by the entire multidisciplinary team and which can be an effective tool for the improvement of interdisciplinary communication.

Errors in Medicine: perception of healthcare professionals in the Lazio Region.

INTRODUCTION: The error in medicine is always the subject of debate in the scientific debates. The purpose of this study is to evaluate the degree knowledge, attitudes and behaviors of health workers towards the error in the health sector. METHODS: A survey was carried out involving 435 health profes- sionals working in health facilities of the Lazio region, of which 312 females (71%) and 123 males (28%) with an age between 21 and 68 years. A structured questionnaire was administered for investigating the experiences and opinions about the errors found in medical prac- tice, the causes underlying them and the mistakes that should never be committed. Data were collected, stratified by sex, age, marital status, year of graduation, years of service and the workplace (medical or surgical). The statistical significance was set at p≤0.05. RESULTS: The 5 errors found more frequently in the clinical prac- tice by health professionals were as follows: errors related to the request for examination (60.9%); errors in the collection of samples (37.5%); errors relating to the delivery of the reports (35.2%); errors due to reporting of examinations (31.7%); errors of history (29.2%). The five cases considered to be the most frequently responsible for such errors were: disorganization (52%); fast (46.4%); tiredness due to excessive workloads, stress (44.6%); negligence and carelessness (41.6%); inattention (41.1). With regard to the errors that you should never commit they were more frequently: exchange of patient or misidentification of the patient (49.2%); administration errors of therapies or medications (47.6%); errors related to surgery (41.6%); errors of prescription therapies or medications (39.3); errors in the reporting of exams (33.6%). CONCLUSIONS: The results of this study shows the importance of a culture of error in medicine among healthcare professionals, those who have already gained practical experience in health care and therefore better able to perform a critical analysis and evaluation of the errors that occur every day. The continuous training of health professionals is fundamental for promoting patient safety and quality in the healthcare sector.

Ulcers caused by bullous morphea: successful therapy with N-acetylcysteine and topical wound care.

Bullous morphea is an uncommon form of localized scleroderma. The pathogenesis is unknown and treatment of coexistent ulcers is difficult. The pathogenesis of bullae formation in morphea is multifactorial, but reactive oxygen species production appears to play a key role. We report a patient with bullous morphea with long-standing ulcers whom we successfully treated with N-acetylcysteine and topical wound care. N-acetylcysteine, an antioxidant sulfhydryl substance, promotes the healing of ulcers in patients with bullous morphea.

Economic impact of childhood obesity on health systems: a systematic review.

The primary purpose of this study is to analyse the costs related to childhood obesity (CO) with reference to different models of healthcare systems. A systematic review of the economic impact of CO on healthcare systems was conducted by searching the main electronic scientific databases. Cost-of-illness (COI) analyses of children aged under 18 years who had been diagnosed as overweight or obese published up to July 2010 were considered. Short- and long-term consequences of CO were taken into account. In order to appraise the quality of the included studies, the British Medical Journal referees' checklist was used. About 3,844 COI analyses were initially found and 10 were finally considered in the current review: two studies referred to Beveridge and eight referred to Voluntary health insurance models. No studies have been conducted within a Bismarck model. Six studies considered in-patient costs, four studies estimated outpatient and primary care costs and seven studies considered pharmaceutical costs. The average quality of the included analyses was medium. The analysis confirmed the significance of CO related costs and the heterogeneity among available studies, which made it impossible to compare the different healthcare models.

[Radical trachelectomy with lymphadenectomy]. / La trachelectomia radicale con linfoadenectomia.

Radical trachelectomy was described for the first time by Dargent in 1987 as an alternative to the traditional radical hysterectomy; it led to a changed procedure in therapy for early cervical cancer in young women who want to preserve their fertility. With this technique it is possible to remove the uterine cervix and parametrius and at the same time preserve the upper part of the cervical canal and uterus. Only a low-risk subset of young patients with early cancer of the cervix are considered eligible for this treatment; to select them histological and clinical staging of the lesion are the most important criteria. We describe the cases of three patients treated with radical trachelectomy between June 1997 and March 1998 in our Institute, reporting in detail the surgical procedure and the results.

[A case of intestinal occlusion caused by endometriosis of the cecum]. / Un caso di occlusione intestinale da endometriosi del cieco.

The purpose of this study is to heighten awareness of intestinal endometriosis, a disease that may mimic other abdominal pathologies (bowel carcinoma, intestinal inflammatory disease, diverticulitis), sometimes found in the emergency setting. The Authors report a case of acute bowel obstruction due to coecal endometriosis with appendix mucocele, peritoneal pseudomyxoma and ovarian endometrioma. The patient was operated on in the emergency setting, a right colectomy was performed and she then received pharmacological suppressive treatment with Gn-RH analogues and danatrol. We remark that preoperative diagnosis is very difficult in those cases that do not have a past history of pelvic endometriosis. An accurate anamnesis regarding the chronology of pain onset (typically only during the menstruation at first), but especially intraoperative histopathologic examination are useful for diagnosis. An increased awareness of intestinal endometriosis in reproductive age women with acute bowel obstruction, associated with an accurate anamnesis of menstrual history may allow pre- or intraoperative diagnosis, which is the clue to a less aggressive operation. Postoperative follow up and hormonal therapy are mandatory.

[The creation of a neovagina with laparoscopic technique]. / Creazione di una neovagina con tecnica laparoscopica.

Vaginal agenesis is sometimes found isolated but more frequently as a part of a malformative syndrome, such as the Rokitansky-Küster-Hauser or the Morris syndrome. In our department the technique of choice for surgical creation of a neovagina is that described by Vecchietti. A pelviscopic approach for this technique has recently been described. Two cases of vaginal atresia are described; one with Rokitansky-Küster-Hauser and the other with Morris syndrome, in which the laparoscopic technique was attempted. Due to the aetiopathogenetic and anatomical differences of the two syndromes, the laparoscopic technique resulted easy in the first case but very difficult in the Morris syndrome case, needing laparotomic conversion. We therefore believe that in choosing the surgical approach, a decisive issue is the type of malformation. Indeed in the Morris syndrome, the contiguity between rectum and bladder makes the laparoscopic technique more difficult.

Biologic prognostic factors in ovarian cancer: a review.

The need of foreseeing the prognosis of ovarian cancer beyond the limits of classical methods based on clinical and histopathological staging has recently caused great interest in a large number of biologic prognostic markers. Studies concern proliferation associated proteins, suppressor genes, abnormal expressions of growth factors, cytokins, and many more. Here some of the most recent and promising factors being studied are described together with their significance for future clinical application.

[Neoadjuvant chemotherapy in the treatment of breast cancer. Results and prospectives]. / La chemioterapia neoadiuvante nel trattamento del carcinoma della mammella. Risultati e prospettive.

Preoperative chemotherapy for breast cancer has been originally proposed in the treatment of locally advanced tumors (T3b-T4) in order to allow radiotherapy or radical mastectomy. Later, it has been employed also for less advanced stages of the disease (T2-T3), to allow conservative surgery. Personal series of 45 patients that underwent preoperative chemotherapy (FAC) for breast cancer stages T2-T3 is reported. A partial response in terms of reduction of tumor volume was obtained in 80% of these patients, a complete response in 6.6% of the cases. In 48.8% a quadrantectomy has been performed, as the lesion diameter was < 2.5 cm after chemotherapy. The survival rate was 70% at 10 years, and 80% for initially T2 tumors, compared with 50% 10 year survival rate in a group of patients with T2 tumors treated before the introduction of neoadjuvant chemotherapy at our Department. Neoadjuvant chemotherapy allows reduction of the initial volume of breast cancer and performance of conservative instead or radical surgery, with better cosmetic results. Moreover these data suggest that they may improve the plateau of the survival curve of patients with locally advanced breast cancer.

[Deep venous thrombosis in pregnancy: diagnostic difficulties and therapeutic indications. Discussion of a clinical case]. / La trombosi venosa profonda in gravidanza: difficoltà diagnostiche e indirizzi terapeutici. Discussione di un caso clinico.

Pregnancy is a risk factor for deep and superficial venous thrombosis because of hemodynamic changes and modifications of the coagulation and fibrinolitic systems. In case of a patient suffering from a congenital or acquired thrombophilia, risk of severe and recurrent thrombosis becomes much higher, with the possibility of a life threatening complication as pulmonary embolism. Recently a number of congenital thombophilic syndromes have been described, in particular congenital hereditary deficit of coagulation inhibitors. Among the acquired pathologies, the antiphospholipid syndrome has been recently object of studies. Diagnostic and therapeutic options are still controversial. The authors present a case of recurrent deep vein thrombosis in pregnancy treated with positioning of a caval filter for the prophylaxis of pulmonary embolism. Diagnostic difficulties are discussed, as the patient presented with low levels of the coagulation inhibitor protein S, and also circulating antibodies anticardiolipin.

[Gn-RH analogs in the treatment of benign gynecologic diseases: current trends]. / Gli analoghi del Gn-RH nel trattamento della patologia ginecologica benigna: orientamenti attuali.

Gn-RH analogues have been recently employed for the treatment of oestrogen-dependent benign gynaecological disorders, such as uterine myomata, endometriosis or metrorrhagia. They induce a "pharmacological castration", inducing a marked reduction of serum oestrogen levels. They proved more effective than other drugs used up to now in the medical treatment of these benign gynaecological diseases. Thus they were initially employed in every case. Later it became clear that Gn-RH analogues need a selective indication. The authors herein report their series of 70 patients with benign gynaecological disorders (45 uterine fibroids, 10 endometriosis, 15 metrorrhagia), treated with a Gn-RH analogue depot for 2-3 months preoperatively. They evaluated the efficacy of the treatment in the group with uterine fibroids in terms of disappearance of metrorrhagia, better haemoglobin level in anaemic patients, reduction of fibroids size allowing for a simpler and less extensive surgery (vaginal surgery, myomectomy, hysteroscopic resection). The authors discuss those cases when preoperative treatment with Gn-RH analogues is not indicated, or should be employed only under careful surveillance (in the preparation of multiple myomectomies, big submucosal myomas). In the group of 10 patients with endometriosis we observed the disappearance of pelvic pain and dyspareunia, whereas the size of endometriomas was only minimally reduced. The authors discuss the usefulness of this treatment in case of patients with endometriosis grade I or II (minimal or mild), with desire of children. In the group of 15 perimenopausal patients with metrorrhagia, 10 became amenorrhoic after termination of treatment, thus avoiding surgery. The major benefit for the other 5 patients was a better haemoglobin level at the time of surgery.

Ondansetron-induced headache. Our experience in gynecological cancer.

Chemotherapy-induced emesis is one of the major problems in the treatment of oncologic patients. Recently, a novel class of compounds, the selective 5HT3 receptor antagonists, has been introduced, achieving a dramatic improvement in the control of emesis. The absence of extrapyramidal side effects adds to their safety and good tolerability. The Authors herein analyse their experience on 269 cycles of chemotherapy in 47 patients treated for gynaecological and breast malignancies, with particular regard to adverse events such as headache. Their most frequent side-effects are headache and constipation, that are usually mild and self-limiting. Nevertheless, in some cases, severe, rebel headache has been reported, leading in our experience in 6.4% of cases to discontinuation of the antiemetic regimen. A previous history of recurrent or severe headache or migraine is not correlated with the occurrence of ondansetron-induced headache, as severe headache occurred after ondansetron only in 28.4% of the patients with positive anamnesis, and 70% of the patients that experienced had never suffered from severe headache before. In those patients complaining of severe headache, the Authors suggest an antiemetic association, with a loading dose of ondansetron i.v., followed by metoclopramide i.m. orally for the following days.

Ondansetron in chemotherapy-induced emesis. Our experience.

UNLABELLED: Chemotherapy-induced nausea and vomiting is one of the major side effects of antiblastic treatment in cancer patients, seriously affecting both the compliance of the patient to therapy and his or her quality of life. OBJECTIVE: The Authors present their experience in the use of ondansetron in 47 patients receiving 186 cycles of chemotherapy for breast or genital neoplasms. RESULTS: Successful control of vomiting was achieved in the first 24 hours, in 74% of the cycles containing cisplatin and 82% of the cycles without cisplatin, if ondansetron was used. On delayed vomiting the difference in results was not as striking as on acute emesis. CONCLUSIONS: The major side effects with ondansetron were headaches (42.4%) and constipation (48.9%). As expected, no extra-pyramidal symptoms were observed in this group, versus 13.3% of the patients treated with metoclopramide.

Infiltrating lobular carcinoma of the breast (ILC). Diagnostic and therapeutic aspects.

Invasive lobular carcinoma of the breast (ILC) is the second most common form of mammary neoplasm after ductal carcinoma. Due to its histological features, characterised by a diffuse infiltration of the tissue by malignant cells with scarce fibrotic reaction, lobular carcinoma often presents clinical and instrumental diagnostic difficulties. The Authors present a retrospective series of 28 patients with lobular carcinoma, with special regard to the diagnostic work-up. Clinical examination misdiagnosed 10 cases, in which only a mild thickening of the breast parenchyma was present. Mammographic false negatives were 21.4% (6 cases). Ultrasonography allowed correct diagnosis in 5 out of these 6 cases. Fine needle aspiration (FNA) had low sensitivity (33% false negatives). ILC constitutes a diagnostic challenge, often requiring the combination of multiple diagnostic tools.

Considerations on the prognostic significance of bone marrow micrometastases in breast cancer.

Research of bone marrow micrometastases in patients with breast cancer was proposed as a prognostic factor in order to detect those patients at high risk for early recurrence. The Authors present a review of current literature and describe the different methods used, with particular regard to monoclonal antibodies. The biological significance and prognostic value of the presence of bone marrow micrometastases in clinically Mo patients with breast cancer are discussed.

Ovarian cysts in the postmenopause: is a conservative treatment feasible?

The incidence of epithelial ovarian cancer reaches a peak between the ages of 50 and 59 years. Therefore any ovarian enlargement in the postmenopause has been treated up to now with prompt surgical exploration. Recently the reliability of ultrasound has allowed a conservative management of small unilocular ovarian cysts even in the postmenopause. The Authors report here their experience on benign masses in postmenopausal women, and discuss the feasibility of ultrasound-guided aspiration of small, anechoic adnexal cysts.
