Discontinuity of marginal artery at splenic flexure and rectosigmoid junction: A systematic review and meta-analysis. Colorectal Dis 2023. [PMID: 37317032 DOI: 10.1111/codi.16624] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Revised: 02/08/2023] [Accepted: 04/02/2023] [Indexed: 06/16/2023]
Abstract
AIM The aim of this study was to provide comprehensive evidence-based assessment of the discontinuity of the marginal artery at the splenic flexure (SF) and the rectosigmoid junction (RSJ). METHOD A systematic review was conducted of literature published to 26 December 2022 in the electronic databases PubMed, SCOPUS and Web of Science to identify studies eligible for inclusion. Data were extracted and pooled into a meta-analysis using the Metafor package in R. The primary outcomes were the pooled PPEs of the marginal artery at the SF and the RSJ. The secondary outcome was the size of vascular anastomoses. RESULTS A total of 21 studies (n = 2,864 patients) were included. The marginal artery was present at the splenic flexure in 82% (95% CI: 62-95) of patients. Approximately 81% (95% CI: 63-94%) of patients had a large macroscopic anastomosis, while the remainder (19%) had small bridging ramifications forming the vessel. The marginal artery was present at the RSJ in 82% (95% CI: 70-91%) of patients. CONCLUSION The marginal artery may be absent at the SF and the RSJ in up to 18% of individuals, which may confer a higher risk of ischaemic colitis. As a result of high interstudy heterogeneity noted in our analysis, further well-powered studies to clarify the prevalence of the marginal artery at the SF and the RSJ, as well as its relationship with other complementary colonic collaterals (intermediate and central mesenteric), are warranted.

Analysis of the Different Lymphatic Drainage Patterns during Sentinel Lymph Node Biopsy for Skin Melanoma. J Clin Med 2021; 10:jcm10235544. [PMID: 34884243 PMCID: PMC8658642 DOI: 10.3390/jcm10235544] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 11/19/2021] [Accepted: 11/23/2021] [Indexed: 12/03/2022] Open
Abstract
In the last two decades, studies of lymphoscintigraphy imaging in lymphatic mapping reported an extreme heterogeneity of skin lymphatic drainage of some skin area, in contrast with the previous scientific literature. The aim of this study was to investigate the presence of any correlations between the topographical location of cutaneous melanoma and the topographical location of sentinel lymph nodes. Data from 165 patients undergoing sentinel lymph node biopsy between January 2013 and May 2021 were analyzed, demonstrating that melanomas in the Lumbar region presented a significant more heterogeneous drainage by site than those in the Scapular region (p < 0.01) and that melanomas in the Subscapular region were significantly more heterogeneous by laterality (unilateral vs. bilateral) than those in the Scapular region (p < 0.05). Results of this study supported the evidence of multiple lymphatic drainage as regards the sentinel node biopsy performed in skin melanoma located on the dorsal subscapular region and lumbar region. For this reason, the association of preoperative lymphoscintigraphy with another imaging evaluation is needed in these critical cutaneous areas. Recent technical developments enabling fluorescence lymphography together with indocyanine green have significantly improved the visualization of lymphatic drainage patterns at a microscopic level. In the preoperative phase, any doubt can be resolved by associating the SPET-CT scan to lymphoscintigraphy, while during the intraoperative phase, an additional evaluation with indocyanine green can be performed in doubtful cases. The aim of the duplex lymphatic mapping (pre and/or intraoperative) is an accurate search of sentinel nodes, in order to reduce the rate of false negatives.

A systematic review and meta-analysis of variants of the branches of the superior mesenteric artery: the Achilles heel of right hemicolectomy with complete mesocolic excision? Colorectal Dis 2021; 23:2834-2845. [PMID: 34358401 DOI: 10.1111/codi.15861] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Revised: 06/29/2021] [Accepted: 07/27/2021] [Indexed: 12/18/2022]
Abstract
AIM Dissection with subsequent ligation and resection of arteries at their origin (central vascular ligation) is essential for adequate oncological resection during right hemicolectomy with complete mesocolic excision. This technique is technically demanding due to the highly variable arterial pattern of the right colon. Therefore, this study aims to provide a comprehensive evidence-based assessment of the arterial vascular anatomy of the right colon. METHODS A thorough systematic literature search through September 2020 was conducted on the electronic databases PubMed, Scopus and Web of Science to identify studies eligible for inclusion. Data were extracted and pooled into a meta-analysis using MetaXl software. RESULTS A total of 41 studies (n = 4691 patients) were included. The ileocolic artery (ICA), right colic artery (RCA) and middle colic artery (MCA) were present in 99.7% (95% CI 99.4%-99.8%), 72.6% (95% CI 61.3%-82.5%) and 96.9% (95% CI 94.2%-98.8%) respectively of patients. Supernumerary RCA and MCA were observed in 3.2% and 11.4% respectively of all cases. The RCA shared a common trunk with the ICA and MCA in 13.2% and 17.7% respectively of patients. A retro-superior mesenteric vein course of the ICA and RCA was observed in 55.1% and 11.4% respectively of all cases. CONCLUSION The vascular anatomy of the right colon displays several notable variations, namely the absence of some branches (RCA absent in 27.4% of cases), supernumerary branches, common trunks, and retro-superior mesenteric vein courses. These variations should be taken into consideration during right hemicolectomy with complete mesocolic excision to ensure adequate oncological resection while minimizing intra-operative complications.

Abstract
The Emergency Medical Service team are often the first to arrive in situations that later turned out to be crime scenes. Therefore, multiple responsibilities derive from their actions, as there is the burden of assisting the parties involved by maintaining the integrity of forensic evidence while, at the same time, mitigating further harm or risks. The aforementioned, however, often lack any forensic training with the consequent risk of alteration of the area and loss of fundamental information for the purpose of further investigation. The purpose of this study, born from the interdisciplinary collaboration between nursing and forensic sciences, is aimed to guarantee the correct approach by emergency professionals at the Crime Scene; in the light of the data currently available regarding intervention strategies, a Data Collection Sheet was drawn up, whose non-immediate compilation would inevitably lead to the loss of important informations. This is a tool not intended for medical examiners, already trained in this field and equipped with elaborate survey cards, but rather an easy-to-use tool that is the prerogative of "laymen" that can prevent emergency healthcare professionals from losing crucial elements that will then be provided to the investigative bodies and consequently to the consultants or experts. The working method involved the research in Literature of already existing operational tools and a bibliographic review of texts, articles and protocols relating to the topic, as well as surveys carried out at national level via email with EMS Operations Centres about the use of a Crime Scene Report Card.

Abstract
BACKGROUND The purpose of this systematic review and meta-analysis was to determine the prevalence of the number of sigmoid arteries (SA) and variations in their origins. METHODS A thorough systematic search of literature through February 2020 was conducted on major electronic databases to identify eligible studies. Data were extracted and pooled into a meta-analysis using Metafor package in R. The primary outcome was the variations in the SA origin (according to modified Zebrowski classification), and the secondary outcome was the prevalence of the number of SA. RESULTS A total of 22 studies (n = 2653 patients) were included. Type 1 modified Zebrowski (separated origins or common trunk of the SA originating from descending recto-sigmoid trunk (DRST)) was the most common origin type of the SA (pooled prevalence estimate (PPE) = 49.67% (95% CI 32. 67- 66.71)), while type 3 (separated origins or common trunk of 1 or 2 SA originating from DRST or superior rectal artery (SRA) and 1 or 2 SA originating from DRST or SRA) was the least common (PPE = 0.18%; 95% CI 0.00-2.82)). Of the Type 1 variants, the not specified (N.S) variant was by far the most prevalent. The number of SA ranged from one to five, with three being the mode (PPE = 42.3%). CONCLUSION This is the most comprehensive analysis of arterial vascular anatomy of the sigmoid colon. In light of the highly variable anatomical pattern displayed by the SA, thorough pre-operative knowledge of their anatomy can be crucial in minimizing incidences of iatrogenic injury.

Abstract
AbstractEndocarditis due to Proteus mirabilis is very uncommon and the optimal surgical and/or antibiotic treatment is not well defined. Guidelines from the AHA and ESC recommend prolonged courses of combined antibiotic therapy but information regarding the clinical presentation, the choice of treatment, the surgical management, and the duration of therapy can only be taken from clinical cases reported in literature. We describe a case of native valve endocarditis due to Proteus mirabilis, successfully treated with antibiotic therapy alone with a review of the relevant literature on this topic.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) is considered to be the gold standard in the early management of acute cholecystitis however, recommendations for routine drain insertion in the acute setting are unavailable. STUDY DESIGN A systematic review of literature review and metanalysis was conducted. All studies comparing drain versus no drain after LC for acute cholecystitis were included. RESULTS Seven studies, with 1274 patients, were included. Postoperative wound infection rates (relative risk (RR) 0.30, 95% confidence interval (CI) 0.10 to 0.88; I2 = 0%) and postoperative abdominal collection requiring drainage (RR 1.20, 95% CI 0.35 to 4.12; I 2 = 0%) were lower in the no-drain group, but this was only significant for wounded infections on subgroup analysis of RCTs. Length of stay hospital (mean difference (MD) -0.49, 95% CI -0.89 to -0.09; I 2 = 69%) and operative time (MD -8.13, 95% CI -13.87 to -2.38; I 2 = 92%) were significantly shorter in the no drain group however this was in the context of significant heterogeneity. CONCLUSION The available data suggests that acute cholecystitis is not an indication for routine drain placement after LC. However, these results must be interpreted with caution due to the limitations of the included studies. In effect, the main issue of this meta-analysis lies on the limitations of the included studies themselves, because of a considerable heterogeneity among the included works, particularly for the inclusion criteria of patients and reported severity of acute cholecystitis. Further work is required to produce evidence which will definitively alter clinical practice. LEVEL OF EVIDENCE Level 2a (systematic review of cohort studies). Oxford CEBM levels of evidence.

Abstract
AIM To provide a comprehensive evidence-based assessment of the anatomical variations of the left colic artery (LCA). METHOD A thorough systematic search of the literature up until 1 April 2019 was conducted on the electronic databases PubMed, SCOPUS and Web of Science (WOS) to identify studies eligible for inclusion. Data were extracted and pooled into a meta-analysis using the Metafor package in R. The primary outcomes of interest were the absence of the LCA and the anatomical variants of its origin. The secondary outcomes were the distance (mean ± SD) between the origin of the inferior mesenteric artery (OIMA) and the origin of the left colic artery (OLCA). RESULTS A total of 19 studies (n = 2040 patients) were included. The pooled prevalence estimate (PPE) of LCA absence was 1.2% (95% CI 0.0-3.6%). Across participants with either a Type I or Type II LCA, the PPE of a Type I LCA was 49.0% (95% CI 40.2-57.8%). The PPE of a Type II LCA was therefore 51.0%. The pooled mean distance from the OIMA to the OLCA was 40.41 mm (95 CI% 38.69-42.12 mm). The pooled mean length of a Type I LCA was 39.12 mm (95% CI 36.70-41.53 mm) while the pooled mean length of a Type IIa and Type IIb LCA was 41.43 mm (95% CI 36.90-43.27 mm) and 39.64 mm (95% CI 37.68-41.59 mm), respectively. CONCLUSION Although the absence of the LCA is a rare occurrence (PPE 1.2%), it may be associated with an important risk of anastomotic leakage as a result of insufficient vascularization of the proximal colonic conduit. It is also necessary to distinguish variants I and II of Latarjet, the frequency of which is identical, with division of the LCA being technically more straightforward in variant I of Latarjet. Surgeons should be aware that technical difficulties are likely to be more common with variant II of Latarjet, as LCA ligation may be more difficult due to its close proximity to the inferior mesenteric vein (IMV).

Abstract
Abstract
OBJECTIVES: The main objective of this Patient Navigation Program in Rio de Janeiro (PNP Rio), Brazil, is to promote adherence to the "60 Day Law", which states that all patients with cancer within the public system should start treatment within 60 days after diagnosis of cancer. Thus, the objectives are: 1.) to establish feasibility of PNP in this setting; 2.) to identify barriers to compliance the Law of 60 days and 3.) to ensure that at least 70% of recruited breast cancer patients begin treatment within the mandated 60-day period. One report by FEMAMA states that only 30% of breast cancer patients in Rio de Janeiro to initiate treatment within the 60-day mandate.
METHODS: From August 2017 to May 2018, one hundred patients aged 33-81 years (mean age 59 years) were recruited for navigation at Rio Image - an advanced breast cancer diagnosis center administered by the state health secretary and located in the capital city of Rio de Janeiro, attending patients from the public system from all 92 municipalities in the state. Patient Navigator (PN), a trained social worker, starts navigation from diagnosis, administering questionnaires to collect: patient population data, dates and information of historical milestones, and patient satisfaction. Patients were followed up by phone, e-mail or text message to identify barriers to initiation of treatment.
RESULTS: Patients presented staging 0-I (17%), II-III (78%) and IV (5%). There were two deaths related to breast cancer in this group. All patients reported at least one barrier, ranging from 2 to 12 barriers (M=5). The barriers to compliance with the "Law of 60 days" were: Fear and fatalistic thoughts (99%), Financial problems (79%), Uncoordinated health care (76%), Health professionals ignore the Law of the 60 days (75%), Need to do staging exams again (52%), Concern about communicating with medical staff (52%), Transport (42%), Difficult in obtain surgical risk consultation (12%), Line of surgeries in hospitals (12%), Difficult of insertion in the regulation system in Primary Care(11%), Patient cannot express herself (5%), Social support(4%), Absent of the immunohistochemistry panel (4%), Cognitive problems (3%), Comorbidities (2%). The PNP had 100% patient satisfaction and in 60% of the cases it helped the patients to start treatment within the period established by law.
CONCLUSIONS: In summary, PNP Rio generated a positive experience for patients in the public health system because it is an intentional and proactive process of assisting the individual through the cancer system, accessing services and actively overcoming barriers to quality care. The PNP Rio did not achieve the success rate of 70% of compliance with the Law as intended (achieved 60%). However, the barriers that the PN can not overcome such as lack of human resources and medical supplies, were informed to health authorities and hospital administrators. This is an opportunity for discussion of reallocation of funds, focusing on the use of scarce resources in prevention and early treatment rather than late-stage disease. In the Brazilian context, PNP may represent an opportunity to implement existing legislation adequately, and as such, would have great potential for integration at the federal, state, and local health systems.

Is the outpatient management of acute diverticulitis safe and effective? A systematic review and meta-analysis. Tech Coloproctol 2019; 23:87-100.

Abstract
BACKGROUND In Western countries, the incidence of acute diverticulitis (AD) is increasing. Patients with uncomplicated diverticulitis can undergo a standard antibiotic treatment in an outpatient setting. The aim of this systematic review was to assess the safety and efficacy of the management of acute diverticulitis in an outpatient setting. METHODS A literature search was performed on PubMed, Scopus, Embase, Central and Web of Science up to September 2018. Studies including patients who had outpatient management of uncomplicated acute diverticulitis were considered. We manually checked the reference lists of all included studies to identify any additional studies. Primary outcome was the overall failure rates in the outpatient setting. The failure of outpatient setting was defined as any emergency hospital admission in patients who had outpatient treatment for AD in the previous 60 days. A subgroup analysis of failure was performed in patients with AD of the left colon, with or without comorbidities, with previous episodes of AD, in patients with diabetes, with different severity of AD (pericolic air and abdominal abscess), with or without antibiotic treatment, with ambulatory versus home care unit follow-up, with or without protocol and where outpatient management is a common practice. The secondary outcome was the rate of emergency surgical treatment or percutaneous drainage in patients who failed outpatient treatment. RESULTS This systematic review included 21 studies including 1781 patients who had outpatient management of AD including 11 prospective, 9 retrospective and only 1 randomized trial. The meta-analysis showed that outpatient management is safe, and the overall failure rate in an outpatient setting was 4.3% (95% CI 2.6%-6.3%). Localization of diverticulitis is not a selection criterion for an outpatient strategy (p 0.512). The other subgroup analyses did not report any factors that influence the rate of failure: previous episodes of acute diverticulitis (p = 0.163), comorbidities (p = 0.187), pericolic air (p = 0.653), intra-abdominal abscess (p = 0.326), treatment according to a registered protocol (p = 0.078), type of follow-up (p = 0.700), type of antibiotic treatment (p = 0.647) or diabetes (p = 0.610). In patients who failed outpatient treatment, the majority had prolonged antibiotic therapy and only few had percutaneous drainage for an abscess (0.13%) or surgical intervention for perforation (0.06%). These results should be interpreted with some caution because of the low quality of available data. CONCLUSIONS The outpatient management of AD can reduce the rate of emergency hospitalizations. This setting is already part of the common clinical practice of many emergency departments, in which a standardized protocol is followed. The data reported suggest that this management is safe if associated with an accurate selection of patients (40%); but no subgroup analysis demonstrated significant differences between groups (such as comorbidities, previous episode, diabetes). The main limitations of the findings of the present review concern their applicability in common clinical practice as it was impossible to identify strict criteria of failure.

Abstract
RATIONALE Retroperitoneal colonic perforation is a rare cause of retroperitoneal abscess. It presents, more frequently in frail elderly patients, with heterogeneous signs and symptoms which hamper the clinical diagnosis. Subcutaneous emphysema with pneumomediastinum and iliopsoas muscle abscess are unusual signs. Colonic retroperitoneal perforation may be consequent to diverticulitis or locally advanced colon cancer. Due to the anatomy of the retroperitoneal space and different physiopathology, diverticular perforation may present with air and pus collection; on the other hand perforated colon cancer may cause groin mass and psoas abscess. We reported 2 cases of colonic retroperitoneal perforation from diverticulitis and locally advanced colon cancer, respectively. Aim of this report is to improve differential diagnosis based on clinical signs. PATIENTS' CONCERNS A 71-year-old man presented with pain in his left side, fatigue, fever, nausea, massive subcutaneous emphysema of the neck, and Blumberg sign in the left iliac fossa. A 67-year-old man presented with abdominal pain, sub-occlusion, left groin mass, left groin, and lower limb pain during walking, negative Blumberg sign. DIAGNOSIS In the first patient the computerized tomography revealed pneumoperitoneum, gas in the mesosigma, pneumomediastinum, wall thickening of the descending colon, and retroperitoneal collection from diverticular perforation. In the second patient abdominal CT scan found thickening of the sigmoid colon adherent to the iliopsoas and fluid collection. INTERVENTIONS In the first patient, a left hemicolectomy extending to the transverse colon, followed by a toilette and debridement of the retroperitoneum were performed. In the second patient, tumor of descending colon perforated in the retroperitoneum with iliopsoas abscess was treated with left hemicolectomy and a drainage of the abscess. OUTCOMES The first patient underwent right colectomy with ileostomy in the 7 postoperative day for large bowel necrosis. He died of sepsis 2 days after. The second patient had regular postoperative and he is still alive. LESSONS The spread of retroperitoneal abscess in complicated colonic diverticulitis is different from that in advanced colonic cancer. The former can present with a subcutaneous emphysema, the latter with a groin mass. Hence a thorough clinical examination and radiological studies are needed to diagnose these conditions.

Abstract
Background: In Rio de Janeiro there is only the opportunistic screening program for women with breast cancer who arrive at health facilities and with a 14% rate of mammography coverage. In countries that have implemented effective screening programs, with coverage of the target population, quality of screening, and adequate treatment, breast cancer mortality has declined. Evidence of the impact of screening on mortality by this neoplasm justifies its adoption as a public health policy, as recommended by WHO. 80% of the population use the public health system (Sistema Unico de Saude - SUS), provided by the government. This system mainly provides conventional mammography. The private insurance system covers the remaining 20%, who have access to modern technologies such as digital mammography or MRI. Aim: The breast cancer organized screening program in the community of the Andaraí, RJ is committed in assisting women asymptomatic 50-69 years from SUS. Methods: The program foresees the participation of these women for an indefinite period, free of charge, and the accomplishment of biennial digital mammography, going through the stages of early detection and diagnosis. In case of positivity for malignant disease, it will be treated properly. Results: Since April 2014 have been 350 women with an average age of 54 years. 100% of them were asymptomatic and 49% had never done before mammography. Only 1 woman presented clinical suspect aged 44 years. The screening program organized by breast cancer in the community of Andaraí, RJ presented a mammographic coverage rate of 70%. The program is contemplated in the healthcare plan of the SUS. Conclusion: Preliminary results of the study suggest that population based organized screening are feasible and age of onset mammography screening should be 50 years in Rio de Janeiro.

Fatal Clostridium perfringens Septicemia After Colonoscopic Polypectomy, Without Bowel Perforation. J Forensic Sci 2016; 61:1689-1692. [PMID: 27654636 DOI: 10.1111/1556-4029.13197] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2015] [Revised: 11/20/2015] [Accepted: 02/13/2016] [Indexed: 11/29/2022]
Abstract
Since its introduction, colonoscopy has played an important role as a diagnostic, therapeutic, and screening tool. In general, colonoscopy is regarded as a safe procedure, but complications may occur. The most dreaded of these complications is colonic perforation. Bacteremia postprocedure may occur, and although it is not uncommon, it rarely results in clinically significant complications. Patients with IBD (inflammatory bowel disease) are a high-risk population for bacteremia, which may leads to bowel wall overstepping by the bacteria. With regard to that, we report a fatal case of gas gangrene complicating colonoscopy polypectomy without bowel perforation in a healthy adult. To the best of our knowledge, only two other cases of retroperitoneal gas gangrene associated with colonoscopy polypectomy without bowel perforation have been described in international literature, but none of which was completed by a molecular biology analysis.

Abstract
Depressed levels of atheroprotective large HDL particles are common in obesity and cardiovascular disease (CVD). Increases in large HDL particles are favourably associated with reduced CVD event risk and coronary plaque burden. The objective of the study is to compare the effectiveness of low-carbohydrate diets and weight loss for increasing blood levels of large HDL particles at 1 year. This study was performed by screening for body mass index (BMI) and metabolic syndrome in 160 consecutive subjects referred to our out-patient Metabolic Unit in South Italy. We administered dietary advice to four small groups rather than individually. A single team comprised of a dietitian and physician administered diet-specific advice to each group. Large HDL particles at baseline and 1 year were measured using two-dimensional gel electrophoresis. Dietary intake was assessed via 3-day diet records. Although 1-year weight loss did not differ between diet groups (mean 4.4 %), increases in large HDL particles paralleled the degree of carbohydrate restriction across the four diets (p<0.001 for trend). Regression analysis indicated that magnitude of carbohydrate restriction (percentage of calories as carbohydrate at 1 year) and weight loss were each independent predictors of 1-year increases in large HDL concentration. Changes in HDL cholesterol concentration were modestly correlated with changes in large HDL particle concentration (r=0.47, p=.001). In conclusion, reduction of excess dietary carbohydrate and body weight improved large HDL levels. Comparison trials with cardiovascular outcomes are needed to more fully evaluate these findings.

Abstract
The aim of the study was to investigate on a possible association between maternal mean platelet volume (MPV) and oxygen-metabolic changes in pregnancies affected by altered maternal-fetal Doppler velocimetry. We considered the altered maternal-fetal Doppler velocimetry group (n = 57) pregnant women admitted to our Institution for a pregnancy complication associated to the event Pre-eclampsia (PE) and intrauterine growth retardation (IUGR), with altered Doppler velocimetry in the umbilical artery ( UA) (high pulsatility index, absence or reverse end diastolic flow (ARED), blood flow cephalisation) and/or bilateral increased resistance in uterine arteries. Out of these cases, 25 pregnancies were complicated by PE and 32 pregnancies were complicated by IUGR. We included 145 normotensive third trimester pregnant women as a normal maternal-fetal Doppler velocimetry control group. From all women, 20 ml of whole venous blood was obtained from the antecubital vein soon after Doppler velocimetry evaluation. MPV was significantly higher in women with abnormal Doppler velocimetry compared to those with normal Doppler velocimetry (8.0 fl [7.0-8.7] vs. 9.1 fl [8.0-10.6], <0.001. Values are median [interquartiles]). We performed a ROC curve in order to find an MPV cut-off able to predict an uneventful event in Doppler velocimetry compromised fetuses (neonatal O(2) support > 48 hrs or intubation and/or pH < 7.2 at umbilical blood gas analysis (UBGA)). An MPV > or = 10 fl was significantly related to the former diagnostic endpoints compared to that of non-compromised fetuses (sensitivity: 45%, specificity: 89.7%, 95 CI: 18.8-66, p < 0.01). Our study suggests that pregnancies affected by Doppler velocimetry alterations, an MPV value > or = 10 fl may be associated with severe oxygen support and/or low UA ph at birth.

Abstract
The aim of this study was to evaluate the correlations between the haematological parameter mean platelet volume and Doppler velocimetry parameters in order to improve clinical management in third trimester complicated pregnancies (pre-eclampsia, PE, and IUGR) affected by altered uterine resistances. Fifty-one patients were included in the abnormal uterine arteries Doppler velocimetry group (25 pregnancies were complicated by PE, 26 pregnancies were complicated by IUGR). Ninety-nine normotensive pregnant women taking no drugs for at least 2 weeks prior to testing and with no difference in gestational age at evaluation, with normal Doppler velocimetry profiles at routine screen, were used as controls. From all pregnant women, 20 mL of whole blood were obtained into citrate tubes after Doppler velocimetry evaluation and analysed for red blood cell counts (RBC), mean corpuscular volume (MCV), haemoglobin (HGB), haematocrit level (HCT), white blood cells count (WBC), platelet counts (PLT), mean platelets volume (MPV) and other biochemical parameters. From all blood parameters studied, MPV was significantly higher in women with altered uterine artery Doppler velocimetry compared with those with normal Doppler profiles (9.4 +/- 1.0 vs. 8.05 +/- 1.2 fL, P<0.001). In the group with altered uterine artery Doppler velocimetry, pregnancies complicated by PE showed a MPV value higher than pregnancies affected by IUGR (9.5 +/- 1.6 vs. 8.9 +/- 1.1, P<0.001). Finally, mean uterine arteries RI values were significantly related to MPV (fL) in both PE and IUGR groups (P<0.01, r=0.37 and P<0.01, r=0.38, respectively). Our study shows that a periodical monitoring of haematological parameters such as MPV can be associated to Doppler velocimetry in order to improve the management of pregnancies with uterine arteries Doppler velocimetry alterations.

Abstract
The authors have examinated 35 patients 4 - 5 years after a previous episode of acute oedematous biliary pancreatitis. 20 patients had been cholecystectomized while 15 had not been operated. The patients of the first group didn't show any impairment of the endocrine or exocrine pancreatic function while the patients who were not cholecystectomized in 4 cases on 15 showed an impairment of the exocrine pancreatic function valued with the elastase-1 test in the stools. In 2 patients there was also a slight impairment of the glucose metabolism. The authors suppose that the persistance of a biliary disease can affect the pancreatic function.

Abstract
OBJECTIVES Show the chronic inflammatory demyelinating polyneuropathy (CIDP) is not only clinically heterogeneous but extremely variable in severity. METHODS Three patients were referred for mild distal paresthesiae lasting more than 6 months and one for inguinal and thigh pain later ascribed to coxarthrosis. Strength was normal in all patients and tactile sensation reduced distally only in one. Tendon jerks were absent, except the knee jerks in one patient, reduced in lower limbs in two and normal in one. RESULTS Electrophysiology showed a demyelinating neuropathy without motor conduction block. CSF protein content was increased in all patients. Nerve biopsies showed de-remyelination with varying degrees of axonal loss. Genetic studies excluded a demyelinating neuropathy associated with duplication or deletion of the 17p.11.2 segment. CONCLUSIONS CIDP patients with pure sensory clinical presentation have been described but are generally more severely impaired. However, because of the mildness of symptoms and the unequivocal electrophysiological involvement of motor fibers, we think that in these cases the term minimal CIDP is more appropriate than sensory CIDP. These cases represent the most benign end of the CIDP spectrum. In our series minimal or even asymptomatic CIDP encompasses 8% of cases.
