Clinical course of severe colitis: a comparison between Crohn’s Disease and ulcerative colitis.

Few data are available about the clinical course of severe colonic Crohn’s disease (CD). The aim of this study is to describe the clinical course of severe Crohn’s colitis in a patient cohort with isolated colonic or ileocolonic CD, and to compare it with the clinical course of patients with severe ulcerative colitis (UC). Thirty-four patients with severe Crohn’s colitis were prospectively identified in our cohort of 593 consecutive hospitalized patients through evaluation of the Crohn’s Disease Activity Index score and the Harvey-Bradshaw Index. One hundred sixty-nine patients with severe ulcerative colitis were prospectively identified in our cohort of 449 consecutive hospitalized patients through evaluation of the Lichtiger score and the Truelove-Witts score. We evaluated the following data/aspects: response to steroids, response to biologics, colectomy rate in acute, colectomy rate during follow-up, megacolon and cytomegalovirus infection rate. We did not find significant differences in the response to steroids and to biologics, in the percentage of cytomegalovirus infection and of megacolon, while the rate of colectomy in acute turned out to be greater in patients with severe Crohn’s colitis compared to patients with severe UC, and this difference appeared to be the limit of statistical significance (Chi-squared 3.31, p = 0.069, OR 0.39); the difference between the colectomy rates at the end of the follow-up was also not significant. In the whole population, by univariate analysis, according to the linear regression model, a young age at diagnosis is associated with a higher overall colectomy rate (p = 0.024) and a higher elective colectomy rate (p = 0.022), but not with a higher acute colectomy rate, and an elevated ESR is correlated with a higher overall colectomy rate (p = 0.014) and a higher acute colectomy rate (p = 0.032), but not with a higher elective colectomy rate. This correlation was significant on multivariate analysis. The overall rate of colectomy in the cohort of patients with severe Crohn’s colitis was greater than that of the cohort of patients with severe UC, but this figure is not supported by a different clinical response to steroid therapy or rescue therapy with biologics. The clinical course of severe Crohn’s colitis requires to be clarified by prospective studies that include a larger number of patients in this subgroup of disease.

Focal active colitis as a predictor of inflammatory bowel disease: results from a single-center experience.

The term focal active colitis (FAC) is conventionally used to describe the presence of isolated cryptitis, characterized by an inflammatory infiltrate consisting of intraepithelial neutrophils and/or neutrophils invading the lumen of the criptae, with no other microscopic alteration of the colonic mucosa and, in particular, without the presence of signs of chronic inflammation. To date, only four studies, including one conducted in a pediatric population, have been performed to evaluate the clinical significance of this disease. The aim of this retrospective study on prospectively-collected data is to evaluate the clinical implications of the focal active colitis, since there still remains a marked uncertainty regarding this topic and about how often such a diagnosis will presage a diagnosis of inflammatory bowel disease (IBD). Clinical, endoscopic, and pathological data were retrospectively reviewed from 30 patients with focal active colitis, who had no other diagnostic findings on colorectal biopsy and no history of chronic inflammatory bowel disease. The histological findings were correlated with clinical diagnoses. Thirty patients (11 males, 19 females; age 24-80 years, median 56 years) (0.5%) out of 5,600 undergoing colonoscopy between January 2012 and December 2016 presented a definitive diagnosis of FAC. Follow-up ranged from 6 to 60 months (median 24 months). At endoscopy, 19 patients (63%) had mild and non-specific changes, such as mild mucosal erythema, while 11 (37%) had normal findings. Eight patients were documented as having irritable bowel syndrome, while nine cases could be attributed to the effects of drugs, five presented FAC as incidental finding, one a diagnosis of infectious colitis, and seven a diagnosis of IBD (4 with Crohn’s disease). FAC was confirmed to be a more significant predictor of IBD than the previous literature would indicate, even if larger prospective studies, targeted to study this relationship, are needed to understand more clearly its clinical significance.

Liver trauma--operative management.

Civilian liver trauma is generally sustained by blunt injury, with management strategies increasingly focusing on selective non-operative strategies and endovascular intervention. Military liver trauma is more often ballistic in nature and almost always requiring operative intervention. This article reviews established and evolving surgical techniques in the operative management of liver trauma.

[Our experience in inguinal hernia recurrences treatment]. / Il trattamento delle ernie inguinali recidive: nostra esperienza.

Reporting their personal experience, the authors focus on characteristics and causes of recurrence, either after traditional surgery or with tension-free technique. They describe difficulties and advantages in open interventions and laparoscopic ones. Facing a relapse it's convenient to assume an "eclectic" behaviour, thinking both of general and specific single patient anatomo-pathologic features.

[Acute neoplastic colic obstructions: therapy and postoperative complications. Our experience]. / Le occlusioni acute neoplastiche del colon: terapia e risoluzione di complicanze postoperatorie. Nostra esperienza.

Authors report their experience about neoplastic large bowel obstructions and present two cases of anastomotic leakage resolution by means of transtomy wash-out. They observe that the most important problem in this surgery is anastomotic leakage which, if small, can be solved in a non operative way. According with literature, they also point out anastomotic leakage is commonly due to the impossibility of a correct preparation of colon to operation in emergency. They conclude it is possible, in case of little leakages, to perform trans-stomy wash out which permits a good toilette and sterilization of the colon.

[Etiopathogenic hypothesis on carcinoma of the gallbladder: our study]. / Un'ipotesi eziopatogenetica in tema di carcinoma della colecisti: il nostro studio.

The authors are interested in determining causes of gallbladder cancer (GBC). By this intention, they theorize a correlation between genetic modifications (which are responsible of malignant transformation of biliary epithelium) and some intestinal infections. From 1999 to 2004 they observed 15 GBC and all 15 gallbladder have been analyzed histologically and from microbiological aspect; by these means from 1999 till 2004 they have studied also 30 persons with colelithiasis. The authors noticed that bile of both groups contained, in three cases in the first and in 8 cases in the second, a germ named Escherichia Coli which normally lives in intestine, while in 10 operated gallbladders of the first group and 12 of the second there was a positive for k-ras. They are studying to confirm their theories.

[Treatment of skin neoplasms with polidocanol infiltrations. Our experience]. / Trattamento delle neoplasie cutanee con infiltrazioni di polidocanolo. Nostra esperienza.

The authors try to explain the importance of day surgery today. They report their 5 years experience in treatment of face and neck skin neoplasms by injections of a sclerosant product as hydropolyethoxydodecan, in case of a difficult good esthetic result with surgery or other therapies because of patients general conditions, such as diabetic ones, or because of their viral nature. Then they affirm to have treated 350 benign and malign tumors with this method. All subjects presented a complete resolution of disease in few weeks and none between them controlled has actually complications or recruitment of neoplasm. They conclude by saying that this result is probably due to local ischemic reaction caused by the substance used.

[Ileum-colon junction benign obstructions]. / Le occlusioni benigne della giunzione ileo-colica.

The Authors discuss on anatomical and functional characteristics of ileum-colon junction, physiological narrowing in alimentary tract and often involved in benign obstruction. They report their series and analyze all inflammatory or not inflammatory diseases potentially involved, by describing them shortly and giving some information about their clinical features and imaging. The treatment of this obstruction will be done as soon as possible, before wall lesions force to make a larger resection.

[Acute pancreatitis: our experience in the light of natural history]. / Pancreatite acuta: nostra esperienza alla luce della sua storia naturale.

The Authors enumerate main steps of acute pancreatitis natural history. Then they discuss their last five years case-report. After having stated that clinical presentation depends on anatomo-pathological conditions, they consider aetiological causes and morphopathogenetic moments involved in the onset and development of this disease. They conclude stating how only proper diagnosis and treatment can prevent its potential evolution in multiorgan failure.

The 2003 Carl A Moyer Award: real-time metabolic monitors, ischemia-reperfusion, titration endpoints, and ultraprecise burn resuscitation.

Real-time metabolic monitoring of varied vascular beds provides the raw data necessary to conduct ultraprecise burn shock resuscitation based on second-by-second assessment of regional tissue perfusion. It also illustrates shortcomings of current clinical practices. Arterial base deficit was continuously monitored during 11 clinical resuscitations of patients suffering burn shock using a Paratrend monitor. Separately, in a 30% TBSA rat burn model (N = 70), three Paratrend monitors simultaneously recorded arterial blood gas and tissue pCO2 of the burn wound and colonic mucosa during resuscitation at 0, 2, 4, 6, and 8 ml/kg/%TBSA. Paratrend data were analyzed in conjunction with previously reported laser Doppler images of actual burn wound capillary perfusion. With current clinical therapy, continuous monitoring of arterial base deficit revealed repetitive cycles of resolution/worsening/resolution during burn shock resuscitation. In the rat model, tissue pCO2 in both burn wounds and splanchnic circulation differed depending on the rate of fluid resuscitation (P <.01 between sham and 0 ml/kg/%TBSA and between 2 ml/kg/%TBSA and 4 ml/kg/%TBSA). Burn wound pCO2 values correlated well with laser Doppler determination of actual capillary perfusion (rho = -.48, P <.01). The following conclusions were reached: 1). Gratuitous and repetitive ischemia-reperfusion-ischemia cycles plague current clinical therapy as demonstrated by numerous "false starts" in the resolution of arterial base deficit; 2). in a rat model, real-time monitoring of burn wound and splanchnic pCO2 demonstrate a dose-response relationship with rate of fluid administration; and 3). burn wound and splanchnic pCO2 are highly correlated with direct measurement of burn wound capillary perfusion by laser Doppler imager. Either technique can serve as a resuscitation endpoint for real-time feedback-controlled ultraprecise resuscitation.

[Mechanical intestinal occlusion due to phytobezoars]. / L'occlusione meccanica intestinale da fitobezoario.

The Authors reporting two cases with ileus by phytobezoar in distal jejunum and ileum, respectively, and discuss the pathophysiologic mechanism responsible for the formation of bezoars. They expose the etiological and clinical factors of this uncommon cause of small bowel obstruction and also discuss the surgical technique that consists in the removal of the phytobezoar through enterotomy.

[A rare salivary gland neoplasm: cystadenolymphoma]. / Una rara neoformazione delle ghiandole salivari: il cistoadenolinfoma.

The authors, after having examined three recent cases, explain some basic concepts about diagnostics and therapy in cystadenolymphoma of salivary glands. As a matter of fact this neoplasia, in spite of its low frequency, is very important because of its still controversial etiopathology and recent tendency in increasing its incidence in females. Today the diagnostic protocol, undertaken after clinical examination, which is necessary, consists of ultrasonography or computerized tomography. But only postoperative histological examination gives a sure diagnosis and can point out main histomorphological characteristics of tumour. Therapeutic approach can be limited to conservative treatment, which is able to respect the parotid gland, its vascularization and innervation.

[GIST of the jejuno-ileal tract]. / I GIST del tratto digiuno-ileale.

Jejunum-ileum stromal tumors give diagnostic and therapeutical problems, especially with regard to histopathological identification and biological behavior. These tumors are very rare in all case report. After gastric stromal tumors these ones are the most frequent of all alimentary tract. They are often incidentally found; because of their potential transformation, they have to be treated by respecting oncologic eradication standards and observing prognostic criteria based on a correct histopathological evaluation (neoplasm localization and dimension, its structure, presence of cytological atypisms, mitotic index, ploidia, surgical resection). Then there has to be a good follow-up program.

[Treatment of substernal goiter. Our experience]. / Il trattamento del gozzo immerso. La nostra esperienza.

The Authors, after having reviewed substernal goitre natural history, report their five-year experience with this disease, underlining clinical features, therapeutic management, positive results. They examine the several proposed classifications and stress haemodynamic and respiratory complications. At last they shortly discuss about diagnostics and, mainly, about correct therapeutic approach which has two aims to resolve the symptomatology and to prevent relapses.

[Idiopathic gynecomastia: our experience]. / La ginecomastia idiopatica: nostra esperienza.

The Authors reporting their experience, discuss some concepts about physiologic evolution of male and female breast. They distinguish between real and false gynaecomastia; stressing the causes of abnormal development of male breast and morphopathological characteristics of gynaecomastia. Careful diagnostic protocol is necessary for a therapeutic approach based on traditional surgery or liposuction: it depends on prevalence of glandular or adipose breast's tissue.

[Diagnosis and treatment of Crohn's disease]. / Morbo di Crohn: diagnosi e trattamento.

The Authors state their ideas and report their experience about diagnosis and treatment of Crohn's disease. After having treated risk and etiological factors, they discuss typical anatomo-pathological lesions. Then they explain clinical diagnostic and surgical choices extensively: they prefer laparotomic approach. The Author's conclude that timely diagnosis spare heavy complications.

[Intrahepatic biliary lithiasis: experience in 20 years]. / La litiasi biliare intraepatica: esperienza di 20 anni.

In confirming that intrahepatic gallstones don't represent a frequent disease in western countries, Authors specify how this incidence is going to grow up slowly, but in a progressive way. In reporting their experience since 1980 to nowadays they point out how different diagnostic procedures and therapy way of acting were in the first and in the second deca. After having explained actual therapeutic direction that is described in literature, they finish by stating how this is often conditioned by complex anatomicopathological picture and by seriousness of hepatic damage that often comes with intrahepatic lithiasis.

[Color-Doppler sonographic mapping for the choice of treatment in variceal disease]. / Il mappaggio eco-color-Doppler nella scelta del trattamento della malattia varicosa.

The Authors, after having reported Huch's classification concerning both large and small saphenas varixes, make a short historical excursus about the most significant operative methods. Then they start explaining how a correct therapeutic approach can't be done without a careful hemodynamic study. After having given data about their case-report, they conclude affirming how today the duplex-scanner permits to obtain an excellent radicality also with not very invasive techniques.

[Anastomotic dehiscence in colorectal surgery]. / La deiscenza delle anastomosi in chirurgia colo-rettale.

Anastomotic leakage represents the most dangerous complication in digestive surgery and, particularly, in colorectal one. Indeed a careful evaluation and modification of all possible risk factors and a correct procedure aren't often enough to overcome a potential postoperative leakage or at least material filtration. The Authors review their series to analyse the role of all possible general and local risk factors and to verify what conditions can suggest an two or three stages operation.

[Antibiotic and immunostimulating prophylaxis in colorectal surgery]. / Profilassi antibiotica e immunostimolante in chirurgia colo-rettale.

The Authors, after considering post-operatory sepsis as cause of failures and as an important economic damage, make among them a distinction according to the arising area and to the seriousness of their manifestations. They, later, describe corrective and prophylactic measures which in colo-rectal surgery ase campulsory assumptions for sepsis prevention. After relating their experience, Authors reaffirm short-term protocol validity and point out validity of alternation of large spectrum molecules in order to avoid possible arising of bacterial resistances.
