Background: The gold standard treatment of symptomatic cholelithiasis is videolaparoscopic cholecystectomy (VLC). The aim of this study is to produce a predictive clinical ultrasound (US) score for difficult VLC to reduce the rate of conversion to open cholecystectomy surgery and intra and/or post-operative complications., Methods: In this prospective study carried out in 2017 we enrolled 135 patients (pts) who underwent VLC in our General Surgery Unit. A specific pre-operative abdominal ultrasound scan was performed to assess gallbladder characteristics for each patient. All US and patients' characteristics were recorded in a standard form in order to obtain a preoperative score and were then added to the intra-operative variables., Results: The analysis revealed a statistical significance between post-operative characteristics and parietal thickness, adhesions, stratifications and volume of gallstones. Comparing the degree of difficulty VLC assessed in the pre-operative stage to the intraoperative score, the sensitivity of the preoperative US scan test is 91.8% while the specificity is 76.7%., Conclusions: The variables which proved statistically significant in predicting a difficult cholecystectomy were: age, parietal thickness >3 mm, adhesions, stratifications, gallstones >2 cm and fixed gallstones. We have definitively defined a predictive score for difficult VLC for which a VLC is to be considered potentially difficult whenever it presents a pre-operative score equal or greater than 4 (and a "easy" one with a pre-operative score less than 4). These findings may prove helpful in further reducing the conversion rate and the rate of intra- and/or post-operative complications.

Introduction: The aim of this study is to perform a review of the English-language international literature concerning thyroid surgery performed through the transoral vestibular approach, to evaluate its flessibility and safety in terms of complications., Materials and Method: The review was carried out on 17 studies of 17 different Authors. The following variables were taken into consideration: first Author's name, nationality, year of publication, number of cases, hospital stay, conversion rate, type of surgical approach, total number of total thyroidectomies and loboisthmectomies, operative time range, intraoperative blood loss range, number and percentage of complications., Results: 736 procedures were performed: 289 total thyroidectomies and 447 loboisthmectomies. Surgical approach was trivestibular in 15 cases and combined (oro-vestibular) in 2 cases. The operative time varies from 43 minutes for a loboisthmectomy to 345 for a total thyroidectomy. Intraoperative blood loss ranges from 3 to 300 ml. Ten cases were converted into open surgery. The hospital stay varies from 1 to 10 days. Complications were: transient recurrent laryngeal nerve palsy in 34 cases, permanent in 2 cases; transient hypoparathyroidism in 62 cases. One case of postoperative bleeding, 22 postoperative seroma, 20 cases of mental nerve injury, 8 cases of operative wound infection., Conclusions: Transoral endoscopic thyroidectomy vestibular approach (TOETVA) is a new surgical method, the use of which exclusively meets the aesthetic needs of some patients. Its specific complication is the injury of the mental nerves. Further studies, however, seem to be necessary, on numerically broader cases, to ascertain the real validity of the method.

The dysregulation of PD-1 ligands (PD-L1 and PD-L2) and CTLA-4 ligands (CD80 and CD86) represents a tumor strategy to escape the immune surveillance. Here, the expression of PD-L1 , PD-L2 , CD80 , and CD86 was evaluated at the mRNA level in 94 patients affected by papillary thyroid carcinoma (PTC) and 11 patients affected by anaplastic thyroid carcinoma (ATC). Variations in the mRNAs in PTC patients were then correlated with clinicopathological features. The expression of all genes was deregulated in PTC and ATC tissues compared to normal tissues. In particular, the downregulation of CD80 was observed above all in ATC. In addition, the increased expression of CD80 associated with longer disease-free survival in PTC. Higher expression of PD-L1 associated with the classical histological variant and with the presence of BRAF V600E mutation in PTC. The increased PD-L2 expression correlated with BRAF V600E mutation and lymph node metastasis, while its lower expression correlated with the follicular PTC variant. The latter was also associated with the CD80 downregulation, which was also related to the absence of lymph node metastasis. In conclusion, we documented the overall dysregulation of PD-1 and CTLA-4 ligands in PTC and ATC tissues and a possible prognostic value for CD80 gene expression in PTC.

Objective: The World Health Organization, the United Nations Children's Fund, and the International Council for the Control of Iodine Deficiency Disorders recommend a median urinary iodine concentration (UIC) in pregnant women between 150 µg/L and 249 µg/L. In the present study, we evaluated whether in the urban area of Cassino (central Italy), after a national salt iodination program (30 mg/kg) was introduced in 2005, the increased demand of iodine during pregnancy was satisfied., Methods: Between January 2016 and April 2017, 99 pregnant women were enrolled to evaluate UIC in spot urine samples, serum level of thyrotropin, free thyroxine, antithyroglobulin and antithyroperoxidase autoantibodies, and thyroid volume by ultrasonography. Eighty clinically healthy non-pregnant women were evaluated as controls., Results: The median UIC was of 97.7 µg/L and 110.3 µg/L, respectively, in control and pregnant women. A significant increase (P < 0.001) of median thyroid volume was found in pregnant women, relative to control women, being, respectively, 10.4 mL (range 3.68-19.49 mL) and 7.16 mL (range 2.57-14.00 mL). A positive correlation was found between thyroid volume and anthropometric parameters, and an inverse correlation was identified between free thyroxine serum levels and anthropometric parameters., Conclusions: This observational study found that the majority of pregnant women and their fetuses appear not to be protected from the detrimental consequences of iodine deficiency. Therefore, the identification of new strategies to increase the knowledge and awareness of the general population regarding the beneficial effects of iodine supplementation during pregnancy is highly required., (Copyright © 2017 Elsevier Inc.

Aim: The aim of our study is to compare the pre, intra- and post-operative variables of the two surgical techniques, to demonstrate if laparoscopic appendectomy can be considered safer and associated to better outcome., Material of Study: A retrospective analysis of 175 patients has been carried out. Alvarado score, time of surgery, analgesic therapy and length of hospital stay calculated. Finally, postoperative complications were recorded., Results: From January 2011 - April 2016 175 patients were enrolled: 128pts underwent laparoscopic technique and 47pts open technique. The average value of Alvarado score is lower in LA group than in OA group just as the average time of surgery and the use of post-operative analgesic therapy., Discussion: LA has become the surgical technique mostly performed for the treatment of simple and complicated acute appendicitis. Our study shows that LA pts are younger with a statistically significant difference CONCLUSIONS: Most of the emergency appendectomies were performed via laparoscopic technique, especially in young patients. Laparoscopy is safer and associated to better outcome., Key Words: Alvarado Score, Laparoscopic appendectomy, Open appendectomy.

Aim: The incidence of incidental gallbladder cancer (IGBC) is estimated at 0.3-2.1%. The purpose of our study is to evaluate IGBC incidence in our department and to establish its predictive factors, considering patients' clinical characteristics and pre-operative ultrasound gallbladder features., Material of Study: From January 2012 to December 2015, 434 patients (225 females and 209 males) were enrolled in this retrospective observational study in our General Surgery Department. To analyze potential predictive factors, we divided all the patients into two groups: patients with and without histological diagnosis of IGBC. We focused our attention on the patients' clinical characteristics and preoperative ultrasound gallbladder measurements RESULTS: Seven cases were post-operatively identified as incidental gallbladder cancer (IGBC) and after histological examination an IGBC incidence of 1.6% was encountered., Discussion: Considering the increasing numbers of video laparoscopic cholecystectomies (VLC) performed worldwide, cases of IGBC are appearing more frequently. In most cases of IGBC, a second surgical look will be necessary because of feasibility and safety procedures., Conclusions: There is no possibility to establish which risk factors might be predictive for IGBC because of a discordance in the literature and a statistical analysis with low sample size. An accurate surgical procedure needs to be performed to reduce the spread of neoplastic cells and, as a result, improve long-term outcomes., Key Words: Incidental Gallbladder cancer, Laparoscopy, Ultrasound.

Introduction: Gallstone ileus is an uncommon condition of mechanical bowel obstruction caused by the passage of a gallstone into the bowel. It occurs more frequently in female patients older than 65 years and often for a biliary-enteric fistula. The pathognomonic features of gallstone ileus - the Rigler's triad - are pneumobilia, ectopic gallstone and bowel obstruction. Less commonly, a gallstone may enter the intestinal lumen through the common bile duct, after endoscopic retrograde cholangiopancreatography, and very rarely in colecistectomized patient., Case Report: A 92-year old colecistectomized male patient was admitted to our unit for the clinical suspicion of bowel obstruction. He was also submitted to ERCP seven months before. Physical examination revealed tenderness in the lower abdomen and CT showed intrahepatic and extrahepatic biliary dilatation and small bowel obstruction with a hyperdense formation in right iliac fossa as gallstone ileus. It was performed an emergency laparotomy with enterotomy and a 5x3 cm gallstone removal. There were no post-operative complications and the patient was discharged 8 days after surgery., Discussion: Cholecysto-duodenal fistulas are most frequently described in worldwide-reports. There are only few cases in literature of gallstone which enter the gastrointestinal tract following endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy through papilla of Vater, without a biliary-enteric fistula, causing gallstone ileus. If the patient is cholecistectomized, gallstone removal alone is required., Conclusion: The differential diagnosis in case of small bowel obstruction should always include gallstone ileus, even if the patient previously underwent a cholecystectomy.

Vitiligo represents the most common cause of acquired skin, hair, and oral depigmentation, affecting 0.5-1% of the population worldwide. It is clinically characterized by the appearance of disfiguring circumscribed skin macules following melanocyte destruction by autoreactive cytotoxic T lymphocytes. Patients affected by vitiligo usually show a poorer quality of life and are more likely to suffer from depressive symptoms, particularly evident in dark-skinned individuals. Although vitiligo is a non-fatal disease, exposure of affected skin to UV light increases the chance of skin irritation and predisposes to skin cancer. In addition, vitiligo has been associated with other rare systemic disorders due to the presence of melanocytes in other body districts, such as in eyes, auditory, nervous, and cardiac tissues, where melanocytes are thought to have roles different from that played in the skin. Several pathogenetic models have been proposed to explain vitiligo onset and progression, but clinical and experimental findings point mainly to the autoimmune hypothesis as the most qualified one. In this context, it is of relevance the strong association of vitiligo with other autoimmune diseases, in particular with autoimmune thyroid disorders, such as Hashimoto thyroiditis and Graves' disease. In this review, after a brief overview of vitiligo and its pathogenesis, we will describe the clinical association between vitiligo and autoimmune thyroid disorders and discuss the possible underlying molecular mechanism(s).

The giant condyloma acuminatum or Buschke-Loewenstein tumor is a rare, sexually transmitted disease. It is an epithelial tumor characterized by its high potential of malignancy towards developing into a highly invasive squamous cell carcinoma. The present case concerns a drug addicted 40-year-old man who smuggled drugs using his rectum. He had a partially ulcerated mass in the perianal area of about 20 x 10 cm. He reported a progressive growth of this neoplasm during the last 3 years associated with perianal pain, obstructed defecation, bad sitting posture, no fever and weight loss. Our first approach was a left laparoscopic loop colostomy for a fecal diversion and antalgic purpose, and biopsy of the perineal mass. Then, he underwent a complete excision of the perianal neoplasm. The pathologist's positive diagnosis of a well differentiated squamous cell carcinoma, evidently necessitated the radicalization of the surgical procedure of abdominal perineal resection. In consideration of the surgical wound depth and size, a VAC Therapy with Negative Pressure Wound Therapy was applied. The BLT incidence rate has been steadily increasing over the last decade especially among male patients. An aggressive surgical approach is usually to get the best oncologic outcome but the difficult management of the perianal wound is challenging. In our experience VAC therapy has been shown to be an effective tool in promoting the healing of the perineal wound after abdominoperineal resection.

Aim: The aim of our study is to focus on hTERT (human Telomerase Reverse Transcriptase) expression to identify tumoral tissue after a comparison to TP53 and KRAS. More than 85% of cancer cells contain genetic aberrations and also overexpression of hTERT, and, in fact, the promoter of hTERT characterizes all malignant cells., Patients and Methods: Our sample is composed of 18 patients, including 10 with CRC that underwent surgical procedure and 8 patients without CRC, which represent the control group. The hTERT gene expression, KRAS and p53 were evaluated by methodical Real Time - PCR on RNA extracted from tumor tissues, peritumoral tissue and control cases., Results: Within the CRC group the evaluation of the tumor tissue showed an increase of hTERT expression with a statistical significance (> 0.1) in 5 of these, also associated with substantial increase of KRAS (> 0.2). The peritumoral tissue assessment showed important increase in KRAS in 4 patients (> 0.2), while hTERT is not found to be particularly increased. The value of p53 did not show any particular significance (<0.1)., Discussion: The analysis of our data leads us to consider that the increase of hTERT is evident in patients suffering from CRC and that some of them will become significant in relation to the increase of KRAS and independent of p53. In peritumoral tissues, however, KRAS increases considerably, instead hTERT maintains a low concentration and this is compatible with the cellular evolution of the neoplastic tissue adjacent to the tumor., Conclusions: hTERT could be used for diagnosis and prognosis in the future, to be able to identify the risk of tumor progression and to set up an adequate therapy.

Introduction: Splenic cysts are benign tumors, accidentally detected using US or CT scan. They are classified into true cyst (primary, 25%) and pseudocyst (secondary, 75%). Conventional treatment of splenic cyst, especially giant, symptomatic and complicated has been open or laparoscopic total splenectomy. Recently, partial splenectomy is recommended as well to preserve its hematopoietic function and homeostasis of blood, but it is not considered safe for complications as intra and post operative bleeding., Case Report: A 46 years old man, martial arts practitioner, underwent US abdomen scan because of left upper quadrant pain, with evidence of a splenic mass. He underwent also CT and MRI, which revealed "oval giant splenic mass of 12 cm diameter located in superior splenic pole that can be firstly referred to cyst". Considered patient's frequency to thoraco-abdominal traumas, we decided to perform a total laparoscopic splenectomy. Surgical treatment was performed with a three trocar technique and lasted 150 minutes. Post-operative follow-up was regular and abdominal drain was removed in 4th POD (Post Operative Day). Patient was discharged in 5th POD. Pathological examination revealed epidermoid cyst., Conclusions: Total splenectomy needs to be performed in cases of giant cyst and in our limited experience it is a safe approach.

Background: Obesity is an independent cardiovascular risk factor and a catalyst of other cardiovascular risk factors, such as hypertension, dyslipidemia, type 2 diabetes mellitus (DM2) and metabolic syndrome., Methods: We analyzed cardiovascular risk in obese patients before and after sleeve gastrectomy (SG). To this end, we studied changes in body mass index (BMI), blood chemistry parameters that characterize the risk of atherosclerosis and instrumental parameters (objective markers of this risk), namely intima-media thickness (IMT) and flow-mediated dilation (FMD), the latter reflecting endothelial function. We also considered purely cardiac parameters-mitral annular plane systolic excursion (MAPSE) and tricuspid annular plane systolic excursion (TAPSE)-which describe cardiac risk more specifically than the ejection fraction. Alteration of one or more of these parameters determines an increase in cardiovascular morbidity and mortality., Results: The results showed that weight loss, in patients undergoing SG, is accompanied by a reduced BMI and a marked improvement in blood chemistry, confirming what has already been shown in many other studies, but the most interesting finding was the effect of SG on the instrumental markers of atherosclerosis. In particular, carotid IMT was significantly reduced (p < 0.001) and FMD significantly improved. MAPSE and TAPSE also improved significantly at both follow-up assessments (p < 0.001)., Conclusions: This study suggests that SG should be considered from a broader perspective, i.e. as a weight loss treatment that also improves obesity-related morbidity and mortality, benefitting both the patient and, in an economic sense, the society as a whole.

Introduction: Peptic ulcer perforation (PPU) is a common surgical emergency and the mortality rate ranges 10% to 40%, especially in elderly patients. Laparoscopic repair achieved encouraging results., Materials and Methods: We enrolled patients performing surgical repair for PPU from January 2007 to December 2015 in our surgical unit. The aim of this retrospective observational study was to compare the results of PPU laparoscopic repair with open technique. The following characteristics of patients were evaluated: age, sex and American Society of Anesthesiologists classification. The site and the diameter of perforation were recorded: gastric, pyloric, duodenal, and the location on the anterior or posterior wall., Results: In total, 59 patients (39 males and 20 females) with a mean age of 58.85 years (±SD) were treated surgically. Laparoscopic repair was accomplished in 21 patients. The mean operative time for laparoscopic repair was 72 minutes (±SD), significantly shorter than open repair time (180 min ±SD). The results demonstrated that laparoscopic repair is associated with a shorter operative time, reduced postoperative pain (4.75 vs. 6.42) and analgesic requirements, a shorter hospital stay (7.5 vs. 13.1), and earlier return to normal daily activities., Discussion: Laparoscopic surgery minimizes postoperative wound pain and encourages early mobilization and return to normal daily activities. The benefit of early discharge and return to work may outweigh the consumable cost incurred in the execution of laparoscopic procedures., Conclusions: Complications in both procedures are similar but laparoscopic procedure shows economic advantages for reducing postoperative hospital stay, postoperative pain, and for a good integrity of abdominal wall.

Aim: The aim of the present study is to report our series of incidental thyroid carcinomas in the last 15 years and their follow-up, discussing therapeutics indications and surgical choices., Patients and Methods: We have considered 1793 patients operated on Surgical Sciences Department of "Sapienza" University of Rome from January 1, 2001 to December 31, 2015. The study was conducted on 83 totally thyroidectomized patients with a real incidental thyroid carcinoma, by clinical, laboratory and instrumental controls. Whole-body scan was the most important test in postoperative evaluation., Results: In our series, the incidence of incidental carcinomas was 4.62%. Compared to the total number of cancer patients, the percentage is 21,9%. In 15.66% of cases there was multifocality and in 7.23% also bilaterality. Regarding the histological type, in all cases they were papillary carcinoma. The size of the neoplastic lesions ranged from a minimum of 3 to a maximum of 10 mm. Whole-body scan revealed lymph node metastasis in 57.69% of patients., Discussion: Comparing these data with our previous studies we have seen a significant increase in incidence of incidental thyroid carcinomas over the years. Our therapeutical choice is total thyroidectomy and complection thyroidectomy after lobectomy, because of a relevant percentage of multifocality and/or bilaterality of these tumors. Many Authors on the contrary prefer a more conservative approach invoking the good prognosis of these tumors. The 57.69% of lymph node metastasis at postoperative whole-body scan comfort us in our setting., Conclusion: Incidental thyroid carcinomas are not uncommon. We consider only tumors until 1 cm in diameter. Multifocality and bilaterality are often present such as occult lymph node metastasis. Our therapeutical choice is total thyroidectomy in order to conduct a proper follow-up.

Introduction: We studied 21 episodes of ingestion of foreign bodies (IFO) among 15 prisoners., Patients and Methods: Rectrospective research in pts admitted to emergency from June 2005 to May 2105. Ingestion, management and pts outcome were analyzed. Prisoners with previous esophagogastroduodenal disease were excluded., Results: All pts were males and ingestions were intentional. Esophagogastroduoduenoscopy (EGDS) was performed in 10pts (8 cases with successful removal, 1 case we did not find anything e 1 of unsuccessful EGDS, that required emergency surgey. 9 pts rejected EGDS: in 2 pts were not necessary.Among the 9 pts that rejected EGDS, 5 discharged voluntary. No mortality neither morbidity. Only 1 pt required surgery.The IFO were 34 (23 sharp, 6 flat,5 indefined). We did not observe any food bolus impaction. Multiple ingestion was found in 11 pts. Recurrent episodes were found in 4 pts., Discussion: Almost all episodes can be treated conservatively with observation and endoscopy but the management of this pts has a financial impact on healthcare cost and on security costs. Prevention strategies are important to predict patient group at high risk for recurrent IFO.

Background: Subclinical hypothyroidism (SCH) and chronic autoimmune thyroiditis (CAT) are linked to an increased risk of atherosclerosis and coronary heart disease (CHD). The aim of this study was to look for positive markers of CHD and correlations with thyroid blood tests in patients with SCH or CAT, but no symptoms of CHD, so as to identify CHD risk conditions that otherwise would likely be missed., Methods: We measured a series of thyroid, clinical-metabolic and cardiovascular parameters in 30 consecutive endocrinology patients enrolled in our ambulatory endocrinological referral center of "Sapienza" University of Rome. (19 with CAT, 11 with SCH) from January 2015 to March 2015. 13 asymptomatic subjects were enrolled as controls. In each patient, we measured a series of 34 thyroid, clinical-metabolic and cardiovascular parameters., Results: in the statistical analysis of collected data, the oblique principal components clustering procedure (OPC) revealed the presence of an interesting mixed cluster, composed of a thyroid parameter (TPO-Ab), a metabolic parameter (homocysteine level) and a cardiovascular parameter (MAPSE), in which we assessed the relationships between the single components. Our preliminary results indicate that in both groups of patients elevated TPO-Ab, when accompanied by reduced MAPSE and increased IMT and homocysteine values, may be taken to indicate the presence of clinically unrecognized CHD., Conclusions: Confirmation of these results in larger series of patients could justify hormone therapy for prevention of CHD in these thyroid patients versus placebo treatment., (Copyright © 2016 Elsevier Ireland Ltd.

Aim: The aim of our study is to compare the outcomes of laparoscopic resection (LR) and open resection (OR) for colorectal cancer surgery evaluating lymph node assessment. It may be important to remove and examine an adequate number of lymph nodes because a more extensive nodal resection has been associated to higher survival rate and lower recurrences., Patients and Methods: 150 patients (74 females and 76 males) with colorectal cancer were enrolled and analyzed from January 2006 to March 2010 in our Unit. 100 procedures were performed with traditional laparotomy and 50 procedures laparoscopically. A strict follow-up was scheduled every 1-3-6 months after surgery and, therefore, every year., Results: Laparoscopic techniques require a longer operating time. 2484 total lymph nodes examined with a mean of 16,56 removed per resection in all procedures. 1632 lymph nodes were removed during open procedures and 852 removed during laparoscopy. The scheduled follow-up demonstrated that local recurrence and distant metastasis presented with no significant differences between two groups and overall survival and disease-free survival were assessed over 5 year in 80% of patients., Conclusions: According to our experience, laparoscopic colorectal surgery is safe and feasible, with better short-term outcomes and oncological adequacy comparable to open approach.

The internal carotid artery agenesis is a rare malformation disorder. We report the case of a 12-year-old boy suffering migraine, who had presented an episode featuring amaurosis fugax, spontaneously regressed. CT angiography images show hypoplasia of the left common carotid artery with loss of opacification of the left internal carotid artery consistent to agenesis. Moreover CT scans through the skull base demonstrate absence of left petrous carotid canal and an hypertrophic left middle cerebral artery originating from an aberrant artery arising from the right cavernous carotid. All diagnostic examinations confirmed the presence of the internal carotid artery agenesis, as Lie's type IV. We started an annual follow up that over the next 7 years did not reveal any change in magnetic resonance angiography images.

Introduction: Anisakiasis is a parasitic infection caused by the ingestion of raw fish contaminated by larval nematodes of Anisakis species. Intestinal or extraintestinal manifestations are rated to > 4% and >1% respectively., Presentation of Case: A 61-year old patient was admitted to our General Surgical and Emergency Unit because of sudden abdominal pain, vomit and constipation. He had eaten raw fish 3 days before admission. Laboratory data showed high levels of WBC and PCR. CT scanning showed "dilation of jejunum and ileum loops, thickening of the terminal ileum and cecum and signs of inflammation of the intestinal wall and mesentery". The following emergency surgical procedure was performed: laparotomy with evidence of obstruction of the small bowels, a giant Meckel's diverticulum, resection of terminal ileum and cecum and ileocolonic anastomosis. At the microscopic examination, the intestinal wall appeared occupied by a transmural inflammatory infiltrate, mainly eosinophilic, edema and nematode larvae, referable to Anisakis, surrounded by necrotic-inflammatory material. Moreover, there was evidence of giant a Meckel's diverticulum., Discussion: Normally, enteric anisakiasis exhibits leukocytosis with eosinophilia and high CRP levels. There are cases of successful medical treatment and other cases of endoscopic treatment avoiding surgical procedure. In our case, enteric Anisakias had not been taken into consideration at the moment of the operation and only histopathology could reveal Anisakis larvae inside the intestinal wall., Conclusion: Our surgical approach is considered in literature as the best one for this clinical presentation. Those patients need to be better studied and more attention should be paid to their history.

Aim: The continued hospitalization after total thyroidectomy is often due to the onset of hypocalcemic complications more than 24 hours after surgery. So it would be important to predict which patients will not develop the hypocalcemic complication to discharge them early. This was the aim of our study., Patients and Methods: Our retrospective study was conducted on 327 consecutive thyroidectomized patients, operated on for benign and malignant diseases. We evaluated the values of preoperative serum calcium levels (Cal0) and of the first postoperative day (Cal1) and two new variables were calculated (dCal and dCaln). The same thing was made on a subgroup of 111 patients in whom also parathiroyd hormone (PTH) values were detected. Statistical analysis was performed with the goal of determining if we could establish a safe criterion for discharge at 24 hours after surgery and if there is a correlation between suitability for discharge and diagnosis., Results: As to discharge, the predictive power of the discriminant function applied was significant both on the total of patients and in the subgroup of 111 patients, but it was clinically unacceptable because it would expose us to a 21% to 27% error rate. It is not possible to identify a threshold, below which to consider patients surely dischargeable. The diagnosis does not appear correlated with the suitability for discharge., Conclusion: On the basis of serum calcium and PTH levels in the first postoperative day, it is impossible to predict which patients can be discharged 24 hours after surgery without incurring in hypocalcemic complications.

Aim: Aim is to demonstrate that surgery can be the best way to reduce the risk of malignancy in choledochal cysts (CC) and how hard can be the diagnosis and the treatment during pregnancy., Case Report: We report a case of a pregnant young woman (36 week) with a Todani's score II CC. After caesarean, due to increasing jaundice, she underwent magnetic resonance cholangiopancreatography (MRCP) and Endoscopic retrograde cholangiopancreatography (ERCP) that confirmed the diagnosis. Surgical operation consisted in "cholecystectomy, resection of the choledocal cyst and poli-jejunum anastomosis. drainage of the abscess in the iv hepatic segment"., Discussion: This case report highlights the difficult diagnosis and consequently treatment of a CC, especially during pregnancy. A significant association of biliary duct cyst and hepato-bilio-pancreatic malignancy has been reported with an age-related incidence., Conclusion: Surgery is considered as the best treatment with a close follow-up because of the risk of recurrent cholangitis and malignant degeneration. This case represents also a challenge because of physiological changes in pregnancy and also because of the risk of fetal mortality and maternal morbidity., Key Words: Choledochal cyst, Colangiocarcinoma, Pregnancy, Todani's score.

Background: We set out to study, through ultrasound examinations, the carotid bifurcation in men and women with/without carotid stenosis to look for anatomical and electrophysiologic differences. We evaluated other variables to look for differences that might explain the dissimilar behavior of this disease in the two sexes and the presence and impact of risk factors., Methods: We examined 974 subjects aged 25 to 88 years (478 men and 496 women) in whom we considered heart rate, smoking status, and the presence of hypertension, diabetes, hypercholesterolemia, and hypertriglyceridemia. Ultrasound examination of the neck vessels included measurement of intimal medial thickness (IMT), vessel diameter, and outflow area/inflow area ratio. We established plaque location, echogenicity and echostructure, and the percentage of stenosis owing to plaque and measured systolic velocity, flow direction, and the depth of detection of these parameters. We used the apnea and hyperpnea test to assess cerebrovascular reactivity., Results: Hypertension and hypercholesterolemia were the most frequent risk factors. Women had a higher heart rate, whereas men had significantly greater IMT. The presence of atheromatous plaque was significantly correlated with age in both sexes, with men having a higher prevalence of carotid plaques. The sexes differed significantly with regard to plaque location, echogenicity, echostructure, and intracranial circulation. Women had a slightly higher blood flow velocity in the intracranial arteries. Risk factors affected plaque formation and extent more in men than in women., Conclusions: These findings suggest that carotid stenosis is a gender-related trait.

Aim: This study is aimed to evaluate the incidence of the postoperative deep vein thrombosis (DVT) and the cell damage from compartment iatrogenic syndrome, analyzing two groups of patients operated laparoscopically, one of which assisted with a Sequential Compression Device (SCD)., Material of Study: A patients' series submitted to laparoscopic surgery over a period at least 90 minutes. The venous flow in the lower limbs was detected with the Echo Colour Doppler method, and only one of the two groups was assisted with the SCD., Results: Between November 2006 and October 2007, 35 patients were evaluated, 21 of them wew assisted with SDC and the remaining 14 patients were the control group. All patients had a follow-up was extended for 5 years at the interval of 7 days, 14 days, 30 days, 3 and 5 years., Discussion: The results were confirmed that the application of SCD is able to neutralize the negative effect of the PNP reducing the possible risk of thromboembolic venous stasis and the improvement of lactic acid and of myoglobinemia are attributable to a reduction of preload. With the use of IPC, it decreases venous stasis, improves venous return and cardiac output increases, preventing cell damage by hypoperfusion., Conclusions: The use of a SCD applied to the lower limbs allows an increase in venous return from the lower limbs so reducing the risk of DVT., Key Words: Cellular damage, DVT, Pneumoperitoneum.

Ultrasonography is the main imaging method for the workup of thyroid nodules. However, interobserver agreement reported for echogenicity and echotexture is quite low. The aim of this study was to perform quantitative measurements of the degree of echogenicity and heterogeneity of thyroid nodules, to develop an objective and reproducible method to stratify these features to predict malignancy.A retrospective study of patients undergoing ultrasonography-guided fine-needle aspiration was performed in an University hospital thyroid center. From January 2010 to October 2012, 839 consecutive patients (908 nodules) underwent US-guided fine-needle aspiration. In a single ultrasound image, 3 regions of interest (ROIs) were drawn: the first including the nodule; the second including a portion of the adjacent thyroid parenchyma; the third, the strap muscle. Histogram analysis was performed, expressing the median, mean, and SD of the gray levels of the pixels comprising each region. Echogenicity was expressed as a ratio: the nodule/parenchyma, the nodule/muscle, and parenchyma/muscle median gray ratios were calculated. The heterogeneity index (HI) was calculated as the coefficient of variation of gray histogram for each of the 3 ROIs. Cytology and histology reports were recorded.Nodule/parenchyma median gray ratio was significantly lower (more hypoechoic) in nodules found to be malignant (0.45 vs 0.61; P = 0.002) and can be used as a continuous measure of hypoechogenicity (odds ratio [OR] 0.12; 95% confidence interval [CI] 0.03-0.49). Using a cutoff derived from ROC curve analysis (<0.46), it showed a substantial inter-rater agreement (k = 0.74), sensitivity of 56.7% (95% CI 37.4-74.5%), specificity of 72.0% (67.8-75.9%), positive likelihood ratio (LR) of 2.023 (1.434-2.852), and negative LR of 0.602 (0.398-0.910) in predicting malignancy (diagnostic odds ratio 3.36; 1.59-7.10). Parenchymal HI was associated with anti-thyroperoxidase positivity (OR 19.69; 3.69-105.23). The nodule HI was significantly higher in malignant nodules (0.73 vs 0.63; P = 0.03) and, if above the 0.60 cutoff, showed sensitivity of 76.7% (57.7-90.1%), specificity of 46.8% (42.3-51.4%), positive LR of 1.442 (1.164-1.786), and negative LR of 0.498 (0.259-0.960).Evaluation of nodule echogenicity and echotexture according to a numerical estimate (nodule/parenchyma median gray ratio and nodule HI) allows for an objective stratification of nodule echogenicity and internal structure.

The heterogeneity of diagnostic criteria of Hashimoto's thyroiditis leads to overdiagnosis and prevents strong conclusions from being drawn in clinical studies. The aim of this study is to propose a comprehensive scoring system. A case-control study compared a set of presurgical features of patients with lymphocytic infiltration of the thyroid (Hashimoto's thyroiditis) and controls, in order to design a multi-criteria scoring system. Given a dichotomous outcome (lymphocytic infiltration of the thyroid), a set of covariates was analyzed in 180 patients after total thyroidectomy. A different validation cohort of 1,171 patients was reviewed and classified according to the score. Variables associated with the diagnosis of Hashimoto's thyroiditis were first assessed by univariate analysis. Analysis showed that TPOAb (area under the ROC curve (AUC), 0.67; 95 % CI 0.57-0.77) and TgAb (0.63; 95 % CI 0.54-0.74) were univariate predictors of the diagnosis of HT, which is largely recognized. Combined covariates were then tested using stepwise logistic regression analysis. The final regression model included TPOAb, TgAb, and thyroid vascularity (AUC 0.72; 95 % CI 0.62-0.81). A scoring system was developed, which has a sensitivity of 45.5 % and a specificity of 89.0 %, with a cutoff of 1.7. The likelihood of incident hypothyroidism was higher (OR 2.30; p = 0.004) in the positive (≥1.7) score group. A scoring system has a better performance than any single predictor and is able to identify the subgroup of individuals at higher risk to develop subsequent hypothyroidism.

Liver abscess is a cause of febrile abdominal pain and usually the origin of a liver abscess is ascending cholangitis, hemathological diffusion, via the portal vein or the hepatic artery, or superinfection of necrotic tissue. Solitary pyogenic abscess with no obvious systemic cause may be secondary to a local event such as the migration of an ingested foreign body. We report the case of a solitary liver abscess caused by an ingested foreign body, a fish bone, migrated through the gastric wall into the left lobe.

Background: Whether the risk of cancer is increased in patients with chronic autoimmune thyroiditis is a controversial issue., Methods: Between May 2005 and October 2012, 3777 fine-needle aspiration cytologies (FNACs) were performed on 2562 patients. Serum FT4, thyroid-stimulating hormone (TSH), anti-thyroglobulin antibody (TgAb), and anti-thyroperoxidase antibody (TPOAb) were determined., Results: Patients with suspicious cytology were younger and presented smaller maximum lesion diameter. In patients with TgAb positivity, suspicious cytology was detected more frequently (9.4%) than patients without TgAb (5.7%; p = .04). No significant difference was recorded between benign and suspicious cytology in the positive TPOAb rate. Risk factors for suspicious cytology were younger age (odds ratio [OR], 0.94), smaller maximum diameter (0.95), single lesion (1.85), microcalcifications (3.45), and TgAb (1.74). Mixed solid/fluid content resulted as being a protective factor (0.34). According to multivariate logistic regression analysis, age, mixed content, and microcalcification confirmed significance., Conclusion: Thyroid nodule malignancy in patients with Hashimoto thyroiditis is not more frequent than in patients without thyroiditis., (© 2014 Wiley Periodicals, Inc.)

Thyroid nodules, with their high prevalence in the general population, represent a diagnostic challenge for clinicians. Ultrasound (US), although absolutely reliable in detecting thyroid nodules, is still not accurate enough to differentiate them into benign and malignant. A promising novel modality, US elastography, has been introduced in order to further increase US accuracy. The purpose of this review article is to assess the thyroid application of US strain elastography, also known as real-time elastography or quasistatic elastography. We provide a presentation of the technique, and of up-to-date literature, analyzing the most prominent results reported for thyroid nodules differentiation. The practical advantages and limitations of strain elastography are extensively discussed herein.

Objectives: Graves' disease (GD) is the most common cause of hyperthyroidism, and accounts worldwide for 60-80% of all cases. The diagnosis is based on clinical findings, and is confirmed by the presence of TRAB, suppression of TSH, and elevation of free thyroxin (free T4), and triiodinethyronin (free T3). GD can be treated by antithyroid drugs, radioactive iodine, or surgery. The aim of this study was to review retrospectively the surgical management, in terms of safety and efficacy, in 50 patients operated in the Department of Surgical Sciences since 2005 through 2010 and followed up at the Endocrinology Unit A of the Experimental Medicine Department. We assessed postoperative complications, which included the presence, persistence and development of ophthalmopathy, transient hypocalcemia, permanent hypoparathyroidism and recurrent laryngeal nerve palsy., Materials and Methods: We analyzed data from 50 patients with GD who were eligible and underwent Total Thyroidectomy (TT). Thirty-nine patients underwent TT for recurrent hyperthyroidism after medical therapy and eleven patients for severe ophtalmopathy. The mean follow up was 41 months (range: 10-70)., Results: Eleven patients had ophtalmopathy before surgery. Four patients developed an ophtalmopathy after surgery. Eleven patients presented hypocalcemia, transient in ten patients and permanent in one patient. Five patients developed a transient disphony. Conclusions. Total thyroidectomy is a safe and radical procedure in Graves' disease treatment. Complications of TT are not different than subtotal thyroidectomy if it's performed by expert surgeons.

Cancer of the colon does not always present with the familiar symptoms. Perforation and penetration of adjacent organs, with abscess formation as the initial presentation, is uncommon. Splenic abscess is a rare clinical entity. The four causes of a splenic abscess described are: primary pyogenic infection, splenic trauma, hemoglobinopathies and contiguous disease. In this paper we report a case of splenic abscess from colon cancer in an 50-year-old man who had a left lower chest contusion two-week before and review pertinent literature. Only 11 reported cases of splenic abscess from colorectal cancer were found in Medline.

Background: Measurement of thyroglobulin (Tg) protein in the washout of the needle used for fine needle aspiration biopsy cytology (FNAB-C) has been shown to increase the sensitivity of FNAB-C in identifying cervical lymph node (CLN) metastasis from well-differentiated thyroid cancer (TC). In this study, we evaluated whether routine measurement of Tg protein (FNAB-Tgp), Tg mRNA (FNAB-Tgm) and calcitonin (CT) mRNA (FNAB-CTm) in the FNAB washout of CLN increases the accuracy of FNAB-C in the diagnosis of suspicious metastatic CLN., Methods: In this prospective study 35 CLN from 28 patients were examined. Histology showed metastatic papillary TC (PTC) in 26 CLN, metastatic medullary TC (MTC) in 3 CLN, metastatic anaplastic TC (ATC) in 3 CLN and 3 metastatic CLN from extra-thyroidal cancers., Results: The overall accuracy of FNAB-C was 84.4%, reaching 95.7% when the analysis was restricted to PTC. Both FNAB-Tgp and FNAB-Tgm compared favorably with FNAB-C and shown diagnostic performances not statistically different from that of FNAB-C. However, FNAB-Tgp and FNAB-Tgm/FNAB-CTm were found useful in cases in which cytology results were inadequate or provided diagnosis inconsistent with patient's clinical parameters., Conclusions: We demonstrated that FNAB-C, Tg/CT mRNA and Tg protein determination in the fine-needle washout showed similar accuracy in the diagnosis of metastatic CLN from TC. The results of this study suggest that samples for Tg protein and Tg/CT mRNA measurements from CLN suspicious for metastatic TC should be collected, but their measurements should be restricted to cases in which FNAB-C provides uninformative or inconsistent diagnosis with respect to patient's clinical parameters.

Objective: To evaluate intrinsic nodule features predictive of an inadequate report in fine-needle aspiration cytology (FNAC)., Design: Single-centre cross-sectional study., Methods: Between May 2005 and April 2011, 3279 ultrasonography-assisted FNACs were carried out and features of nodules recorded prospectively. Univariate logistic regression analyses were performed to estimate the association between nondiagnostic cytology and variables such as age, gender, single nodule, maximum nodule diameter and estimated volume., Results: Inadequate or nondiagnostic samples were reported in 1195 FNACs. All diameters were found to be predictors of nondiagnostic cytology; estimated nodule volume, on the other hand, was not. Nodules with a diameter <10 mm were more frequently nondiagnostic (OR 1.65, 95% CI 1.40-1.94, P < 0.001). Neither micro- nor macrocalcification increased the risk of inadequacy. On the contrary, mixed lesions were more frequently diagnostic (OR 0.68, 95% CI 0.85-0.80, P < 0.001). Solid nodule aspiration was performed more easily on isoechogenic nodules (OR 0.64, 95% CI 0.54-0.77, P < 0.001); the same procedure was more cumbersome on hypoechogenic lesions (OR 1.87, 95% CI 1.62-2.16, P < 0.001). Increased vascularization did not cause a significant increase in the nondiagnostic results. Blurred margins increased the inadequacy rate (OR 1.45, 95% CI 1.24-1.69, P < 0.001), while presence of a hypoechogenic halo decreased it (OR 0.67, 95% CI 0.54-0.82, P < 0.001)., Conclusions: Some ultrasonographic features suggestive of malignancy may be predictive of inadequate cytology. Patients must be notified that the FNA report may be nondiagnostic and that this represents a limitation of the technique related to the structure of lesions., (© 2012 Blackwell Publishing Ltd.)

Introduction: Giant anal condyloma also called Buschke-Löwenstein tumor is a rare sexually transmitted disease involving anogenital region with potential malignant degeneration into invasive squamous carcinoma. Complete surgical excision is the treatment of choice and often wide wounds are necessary to reach clear margins and prevent recurrence., Presentation of Case: The authors present two cases treated with an S-plasty rotating and a bilateral house advancement flap respectively with good functional result., Discussion: Giant anal condyloma also called Buschke-Löwenstein tumor is a large exophytic, cauliflower-like mass that is characterized by local aggressive behavior. Immunosuppression favors rapid growth of the condylomas and increases the risk of their malignant transformation. In limited lesions primary excision can be safely performed leaving wounds open to granulate while in more extensive lesions flap or skin graft coverage is preferable to decrease the length of recovery and minimize risk of severe anal stricture. Abdominoperineal resection should be performed for more extensive lesions with deep invasion, malignant transformation or tumor recurrence., Conclusion: Giant anal condyloma also called Buschke-Löwenstein is a rare pathology with mainly sporadic single center experience reported in literature. Surgical complete excision remains the best treatment although elevate should be eventual recurrence. No sufficient data are available to recommend any medical treatment such as interferon, radiotherapy or chemotherapy., (Copyright © 2013 The Authors. Published by Elsevier Ltd..

Calcitonin (CT) is an important clinical marker for the diagnosis and follow-up of medullary thyroid carcinoma, although it is not absolutely specific. Some authors have reported C-cell hyperplasia in a number of thyroid specimens affected by Hashimoto's thyroiditis. The association between thyroiditis and hypercalcitoninemia is still controversial because some authors have reported low CT levels. The aim of this study is to evaluate the basal CT values in patients with and without thyroid autoimmunity. From May 2005 to February 2010, 1073 patients underwent ultrasonography-guided fine-needle aspiration cytology at the Thyroid Center of Sapienza University of Rome, with evaluation of basal serum FT4, FT3, TSH, and antithyroid peroxidase (anti-TPO) antibodies as well as CT levels. Forty-one patients presented a basal CT level above the reference upper limit. The mean serum CT was significantly lower in women than in men (4.28 ± 6.63 vs 7.50 ± 25.50  pg/ml; P<0.01). Basal serum CT was not significantly higher in patients showing anti-TPO Ab positivity (4.71 ± 6.46 vs 4.84 ± 13.11  pg/ml; P>0.05). Importantly, the rate of 'suspicious' CT values (above the 10  pg/ml cutoff) was not significantly different between patients with or without thyroid autoimmunity (3.9 vs 3.0%). Patients with hypercalcitoninemia suffering from chronic autoimmune thyroiditis should undergo the same clinical evaluation procedure as patients do without thyroid autoimmunity.

Unlabelled: Uncontrolled hyperthyroidism in pregnancy is associated with an increased risk of perinatal complications. The state of the art discussed here has been derived through a wide MEDLINE search throughout English-language literature by using a combination of words such as hyperthyroidism, propylthiouracil (PTU), methimazole, rituximab, and pregnancy to identify original related works and review articles. Thioamides are the main first-line therapeutic options, whereas beta-blockers and iodine are second-choice drugs; surgery is resorted to only in exceptional cases. Methimazole and PTU reduce the production of thyroid hormones by selectively inhibiting thyroid peroxidase. PTU was once considered to be the first-choice drug in the treatment of gestational hyperthyroidism; however, the United States Food and Drug Administration now recommends it as a second-line thioamide, which should be used solely by women in their first trimester of pregnancy. Thyroidectomy is to be carried out only in pregnant women affected by life-threatening, uncontrollable hyperthyroidism, or in cases with thioamide intolerance., Target Audience: Obstetricians & Gynecologists, Family Physicians, Learning Objectives: After completion of this article, the physician should be better able to choose appropriate therapies for hyperthyroidism in pregnant women, assess the risk of possible complications due to maternal hyperthyroidism, and evaluate strategies for patient follow-up.

Background: Non-recurrent inferior laryngeal nerve (NRILN) is usually discovered during thyroid surgery. It is often associated with vascular abnormalities that can be detected with magnetic resonance imaging (MRI) or duplex ultrasound scan. The aim of this study was to compare the diagnostic sensitivity of ultrasonography with MRI to identify the vascular abnormalities associated to NRILN., Patients and Methods: We revised 2713 total thyroidectomies to select patients with NRILN. The NRILN was identified in 17 patients (0,6%). A postoperative ultrasonic duplex scanning and a MRI was performed in 15 cases as 2 patients refused to submit to the exams., Results: At MRI an unique origin of common carotid trunk and a concomitant aberrant retroesophageal subclavian right artery was showed in 11 patients. In 2 cases vascular abnormality consisted in separated origin of supra-aortic arteries. At duplex ultrasound scan only in 2 patients was impossible to identify vascular abnormalities detected at MRI. Tthe diagnostic sensitivity of duplex ultrasound was 84,6%., Conclusions: Preoperative duplex ultrasound is a non invasive method with high diagnostic sensitivity that can easily complete the preoperative thyroid ultrasonography.

Objectives: Iodine deficiency is still a notable health-care problem in several regions of Europe and can be responsible for maternal and fetal goiter, miscarriages, stillbirths, reduced fetal growth, congenital hypothyroidisms, damaged reproduction in adult life, and inadequate development and maturation of the fetal brain, which is the major preventable cause of mental defects. The aim of this study was to assess the medical students' knowledge and practices regarding the program of iodized-salt-use and active iodine prophylaxis program launched by the Italian Ministry of Health., Materials and Methods: A self-administered, anonymous, 19 single-item questionnaire was developed. We have collected 294 filled forms: 86 from first-year, 118 from fourth-year and 90 from sixth-year medical students at the First Medical School of 'Sapienza' University of Rome, Italy, in May 2009., Results: Two hundred eighty four students (96.6%) affirm that they know of the existence iodized salt, even though only 199 (67.7%) report personal consumption. This level is quite far from the target (consumption by almost 80% of the general population) suggested by the international literature. No statistically relevant difference was observed between the answers of male and female students., Conclusions: Our study proves that clinical students have a more detailed knowledge on iodized salt if compared with pre-clinical students, but such knowledge remains overall defective and in some cases absolutely incorrect. Additional education is probably needed to prepare physicians to play a critical role in counseling about iodine prophylaxis.

Objective: To evaluate whether pattern III of color Doppler Ultra-sound may identify malignant nodules., Materials and Methods: We have retrospectively analyzed data pertaining to 1090 patients of both genders (230 males, 860 females), with an average age of 53 years (min 17 years, max 81 years), who underwent thyroidectomy in Department of Surgical Sciences of Sapienza University of Rome since January 2003 through June 2009. We correlated color-Doppler characteristics and histological features through statistical analysis so as to verify statistical correlation between them., Results: Our study showed that 164/273 (60.1%) patients with malignant disease were associated with vascularization pattern III. Regarding benign disease, 152/268 (56.7%) patients showed a pattern of vascularization 3 at ultrasonography. The statistical analysis was not able to show any correlation between pattern III and malignancy., Conclusion: Pattern III cannot be used to predict malignancy with confidence, and FNA is still mandatory to rule out the nature of the nodule.

Background: : Basiliximab (B), an anti-CD25 monoclonal antibody, may represent an alternative to steroids (S) in immunosuppression after liver transplantation (LTx). The aim of this prospective randomized clinical trial was to compare B with S in a cyclosporin A (CsA)-based immunosuppression regimen in primary LTx., Methods: : Forty-seven adult recipients of LTx were randomly assigned to receive B or S. CsA was administered at the initial dose of 10 mg/kg/day and adjusted to the target C2 level of 800 to 1000 ng/mL by day 7. Clinically suspected acute cellular rejection (ACR) was histologically confirmed. Endpoints include ACR, survival, and disease-free survival., Results: : In group B (26 patients), there were seven biopsy-confirmed ACR with an ACR rate of 15.4%; in group S (21 patients), 8 ACR with an ACR rate of 28.6% (P=n.s.). Cumulative survival at 36 months after transplantation was 84.3% for group B and 61.0% for group S. In hepatitis C virus patients (n=20: 12 in group B, 8 in group S), the ACR rate was 25% in group B and 50% in group S. The incidence of infection and other adverse events was similar in the two treatment groups., Conclusions: : B may represent a valid alternative to S in the induction of immunosuppression in LTx. Further studies of basiliximab in a large cohort are needed.
