Epiploic Appendagitis Clinically Masquerading as an Acute Diverticulitis.

Acute diverticulitis is a prevalent surgical condition that typically presents with lower abdominal pain and tenderness. However, the clinical and laboratory findings of diverticulitis are non-specific and other conditions may give similar manifestations. We present the case of a middle-aged woman with a left lower quadrant abdominal pain and fever of three days duration. On examination, she had tachycardia and localized tenderness in the left iliac fossa with rebound tenderness. There were no signs of peritonitis, including the rigid abdomen and decreased bowel sounds. The laboratory findings were suggestive of an inflammatory or infectious process. A computed tomography scan of the abdomen demonstrated a fat-density lesion anterior to the descending colon representing epiploic appendagitis. The patient was managed conservatively with non-steroidal anti-inflammatory drugs (lornoxicam 8 mg). The patient experienced gradual improvement and was discharged after four days of hospitalization. No surgical intervention was needed. The case highlighted the importance of considering epiploic appendagitis in the differential diagnosis of acute diverticulitis. An accurate diagnosis will prevent the patient from having unnecessary surgeries as conservative management is often sufficient in patients with epiploic appendagitis.

Food Insecurity and Health-Related Quality of Life: A Cross-Sectional Analysis of Older Adults in Florida, U.S.

Individuals 65 years or older will comprise an estimated 20.0% of the U.S. population by 2030. This study investigated the association between food insecurity and health-related quality of life (HRQoL) among an older adult population (n = 234). HRQoL was measured using Healthy Days, a validated survey tool developed by the Centers of Disease Control and Prevention. Food-insecure individuals were more likely to report ≥14 physically unhealthy days (OR = 1.49, 95% CI 0.47-4.78) and ≥14 days with activity limitations (OR = 4.07, 95% CI 0.68-24.1). Although nonsignificant, the findings highlight food insecurity as a potentially important social determinant of health throughout the life course, including at an older age.

Prevention of fluid effusion in kidney transplantation with the use of hemostatic biomaterials.

BACKGROUND: Fluid effusion (blood, lymph, or urine) in kidney transplantation may give rise to several complications, directly, such as hematoma, seroma, lymphocele, and/or urinoma, or consequently, such as increased infection risk, longer hospital stay, graft compression--with or without functional impairment--and necessity of further hospitalizations. The aim of this study was to evaluate effectiveness of hemostatic biomaterials in prevention of fluid effusions, especially lymphocele in kidney transplant patients. METHODS: We selected 40 patients who underwent kidney transplantation from 2009 to 2012 in which we used hemostatic biomaterials, and compared their results with those of other transplant patients from our center in which we did not used these biomaterials. Evaluated parameters were: fluid effusion, graft function, quality and quantity of drainage, blood count, and operative time. RESULTS: There was no difference in operative time. The incidence of complications on which biomaterials can have a role decreased; particularly, we observed a reduction from 24.21% to 7.5% of fluid effusions (lymphocele). There was no evidence of complications due to biomaterials. CONCLUSIONS: Hemostasis is important in surgery, and in kidney transplantations lymphostasis also has a significant role. In addition to the traditional hemostatic methods, recently some biomaterials, with the purpose of providing atraumatic hemostasis, were added. In our experience they are easy to use, and their use has proved to be effective for both hemostasis and lymphostasis with consequent reduction of fluid effusions.

Complicated diverticulitis in kidney transplanted patients: analysis of 717 cases.

INTRODUCTION: This study aims to investigate possible risk factors for diverticulitis in kidney transplant recipients affected by colonic diverticulosis. METHODS AND RESULTS: We investigated 717 patients transplanted between 2000 and 2010. Diverticular disease was endoscopically diagnosed in 17 of 717 examined patients. Eight patients were diagnosed with autosomal dominant polycystic kidney disease (ADPKD); 9 of 17 patients underwent emergency surgery. We performed Hartmann's procedure on all patients, with a second stage performed at least 6 months later. DISCUSSION: Although the incidence of colonic diverticular perforation in kidney transplanted patients is similar to that observed in the general population, perforation in immunosuppressed patients is associated with a higher morbidity/mortality rate. In our study, the incidence of perforation is 1.25% (9 of 717), with almost half of the cases observed in patients with ADPKD (4 of 9). Such an observation is consistent with published data, in which patients with ADPKD are reported to more frequently develop colonic diverticulosis and its complications. One possible explanation might be related to a belated diagnosis of diverticulitis, which could initially simulate an inflammatory disease as a consequence of renal cysts. Also, steroids seem to be a predisposing factor for colonic perforation in these patients. CONCLUSIONS: A timely surgery can significantly reduce mortality. In cases of elective surgery, mortality and morbidity are similar to those of immunocompetent patients; accordingly, this is the goal to be pursued. Early signs and symptoms are often masked by immunosuppressive therapy. In these patients, surgeons should always perform (1) abdominal computed tomography scanning and, in the presence of diverticulitis, reduce or withdraw immunosuppressive therapy; and (2) early surgery, with Hartmann's procedure being, in our opinion, the best choice. Before transplantation, elective surgery for colonic resection should be considered in patients with ADPKD or with a history of 1 or more episodes of acute diverticulitis who then regressed with medical therapy.

Complete response to preoperative chemoradiation and survival in esophageal cancer: a pooled analysis of three single-institution phase II trials.

This pooled analysis was performed using individual patient data from three phase II trials that included on the whole 113 esophageal cancer treated preoperatively with chemoradiotherapy (CRT), in order to analyze the efficacy and survival outcomes according to the achievement of the pathologic complete response (pCR). Thirty-nine patients were treated with 5-fluorouracil/cisplatin and RT (40 Gy), 33 patients received paclitaxel/cisplatin weekly during weeks 1-6 with and RT (46 Gy), 41 patients were treated with induction bio-chemotherapy with cetuximab and FOLFOX-4 followed by concomitant cetuximab and RT of 50.4 Gy. One hundred and two out of 113 resected patients were included in the survival analysis. The median overall survival (OS) time for the whole population was 21.5 months. The 12, 24, and 36 months OS rates were 85.4, 45.2, and 33%, respectively. The difference in survival probability between patients with pCR and patients with partial response or stable disease after treatment was significant (P= 0.0002, hazard ratios = 0.21, 95% CI 0.18-0.60). On multivariate analysis, the pathologic response and histology were the only covariates independently associated with OS (P= 0.0157 and P= 0.0212, respectively). In our series, complete responder patients had a significant longer survival probability after treatment when compared to patients with partial response or stable disease.

Intravascular lipoma from iliofemoral tract.

Lipoma is a benign tumour composed of well-differentiated adipocytes and is the most common soft tissue mass. We present a case of an intraluminal lipoma of the iliofemoral axis presenting as lower limb venous obstruction. In our case, definite diagnosis is impossible as there is aspecific symptomatology and radiologic imaging methods are not able to provide diriment data, considering rarity of the disease. Therefore, we could make correct diagnosis only intraoperatively. We preferred a direct reconstruction of the wall of vein. At 12-month follow-up, we have had complete disappearance of symptoms and functional diseases.

Effects of voriconazole on tacrolimus metabolism in a kidney transplant recipient.

Infection occurs frequently in the organ transplant recipients during the post-transplant period because of immunosuppression. Therefore, prophylactic antimicrobial agents are often used. The azole antifungals, widely prescribed prophylactically, are known to have many drug-drug interactions. This report presents a case of drug-drug interaction between voriconazole and tacrolimus in a kidney transplant recipient. Voriconazole treatment led to a dramatic increase in tacrolimus concentration that required its discontinuation in spite of the manufacturer's guidelines that recommend a reduction of tacrolimus dosage by one-third. The present drug-drug interaction can be attributed to a strong inhibitory effect on cytochrome P450-3A4 activity by voriconazole. When voriconazole and tacrolimus are coadministered, close monitoring of tacrolimus blood levels is recommended as the rule-of-thumb reduction of tacrolimus dose by one-third may not be satisfactory.

In situ elongation patch in right kidney transplantation.

BACKGROUND: A short right renal vein complicates transplantation causing traction and difficulties during anastomosis. When we perform a kidney transplantation from a cadaveric donor, this problem may be resolved by using the vena cava to create a venous duct. This elongation technique is proposed to be performed during bench surgery. We propose a small change in the technique: execution of an "elongation patch" during harvesting and under cold perfusion. MATERIALS AND METHODS: From January 2004 to June 2006, we performed 12 in situ (during the harvesting procedure) vena cava elongation patches. In these cases, the right renal vein was too short. The elongation patch was used in only 8 transplantations. In the other 4 cases we sacrificed the patch to perform a direct venous anastomosis due to favorable recipient anatomical characteristics. RESULTS: The 8 transplantations performed with the elongation patch did not show vascular complications and the venous anastomosis was easy to perform. CONCLUSIONS: The "extension patch" was not associated with a greater incidence of vascular complications. Using the elongation patch during the harvest showed some advantages: performed during cold perfusion with a reduction in bench ischemia; the anatomical relationships are preserved so we can perform a calibrated suture; the perfusion of the organ allows us to observe the integrity of the anastomosis. This technique did not significantly increase the harvesting time.

The finding of vascular and urinary anomalies in the harvested kidney for transplantation.

INTRODUCTION: In kidney transplantation, anatomical vascular and excretory anomalies may represent causes of failure. Today's surgical techniques have made the most of the organs with anatomic anomalies and iatrogenic injury successfully used for transplantation. MATERIALS AND METHODS: From January 2000 to June 2006, we harvested 230 kidneys, of including 88 kidneys (20%) with vascular, urinary, or vascular-urinary anomalies; 64 kidneys were implanted and 15 were sent to other transplantation centers. Only 9 kidneys were not appropriate for transplantation. RESULTS: All patients who received kidneys with the above-mentioned anomalies were carefully examined after the transplantation and short-term and long-term complications were evaluated with respect to controls without anomalies. DISCUSSION: Renal anatomic anomalies are frequently observed during kidney transplantation and may produce postsurgical complications. However, the presence of these anomalies does not necessarily imply the impossibility of using the kidney for a transplant, especially because of improved surgical techniques. Our experience in transplantation procedures showed that even if kidneys present the above-mentioned anomalies they can still be considered appropriate for transplantation when we perform a correct harvesting/back-table transplant surgery. So vascular and urinary anomalies have to be considered always an incentive to research new surgical solutions and to perform a careful surgical technique.

Older kidneys donor transplantation: five years' experience without biopsy and using clinical laboratory and macroscopic anatomy evaluation.

INTRODUCTION: The exponential increase in organ demand is not associated with a similar increase of available kidneys. This emergency led to expanded criteria to consider a kidney transplantable. The aim of this retrospective study was to explain our use of older donor kidneys without biopsy. MATERIALS AND METHODS: Between 2000 and 2005, 58 older kidneys were harvested: 27 were transplanted in our center; 13 were discarded; and 18 were transplanted in other centers. We considered 3 factors to define kidney quality: macroscopic anatomy, multiple factors linked to the donor, and clinical-laboratory data. After transplantation, we observed the patients for at least 1 year and up to 6 years. DISCUSSION: At 1 year, 24/27 (89%) patients had a functional kidney, 2 patients showed an initial renal failure and 1 patient lost the kidney. At maximum follow-up, 19 patients (70%) had functional kidneys, 4 with initial renal failure. These results compared with the kidneys harvested using Standard Donor Kidney Criteria are acceptable. Obviously we need long-term follow-up to increase, the amount of data and obtain a definitive outcome. CONCLUSION: Biopsy is the gold standard for the definition of an older kidney's quality. When a biopsy is not feasible, the study of the macroscopic anatomy the kidney's donor and of some donor's parameters represent an acceptable biopsy alternative, being able to rescue some organs that would be otherwise lost.

Healing of surgical incision in kidney transplantation: a single transplant center's experience.

INTRODUCTION: Impaired healing of the surgical incision represents a common complication after kidney transplantation. We led a retrospective study seeking to understand the factors linked to these complications and reasons for their reduction during the last year. PATIENTS AND METHODS: From January 2000 to April 2004, 170 consecutive kidney transplantations were performed in a homogenous patient population. We evaluated the influence of following factors to determine impaired healing of the incision: antirejection drugs, overweight/obesity, age, delayed graft function (DGF), diabetes, and abdominal wall reconstruction technique. RESULTS: Among 165 patients we observed 26 (15.76%) cases of impaired healing of the surgical incision: 17 (65,38%) with first-level and nine with second-level wound complications. CONCLUSIONS: Impaired healing of the surgical incision influences the outcome of kidney transplant patients. In our study we observed that cyclosporine and tacrolimus similary affected the incision's healing. It was not possible to evaluate the role of basiliximab. A univariate analysis of the factors related to complications revealed overweight and DGF. However, all patients developing second-level complications showed more risk factors. Patients who had not had reconstruction of the muscle layers showed a greater incidence of surgical complications, whereas patients who had skin sutured with an intradermic technique did not show an increased risk.

Transplantation and young surgeons in Italy.

The relation between young surgeons and transplantation has always been a "love and hate" one. Until a few years ago this branch of surgery was seen as pioneering, with extreme and and extensive training, and was reserved to few elected members. Nowadays things are different. In this article we try to understand the true reasons that young Italian surgeons avoid transplantation surgery.

Anorectal atresia treated with non-continent pull through and artificial bowel sphincter: a case report.

Anorectal atresia, which is classified as a low anorectal malformation, is characterised by the absence of the anal verge and by variable rectal atresia. In some cases, which have been classified as rectal agenesis, the atresia is associated with the absence of the internal sphincter. The therapeutic options are definitely surgical, aiming to relieve the bowel occlusion and to restore faecal continence by lowering the cul-de-sac to the perineum. We present the case of an adult patient with congenital rectal agenesis, double fistula (cul-de-sac-urethra and cul-de-sac-perineum) and caecostomy since birth. The patient was treated with a resection of sigmoid-rectum for the presence of a 20-cm faecaloma in the cul-de-sac, with a non-continent pull-through, and with implantation of an artificial bowel sphincter. Despite some difficulties in managing the device and a slight symptomatic mucosal prolapse, the results after 30 months have so far satisfied both the patient and the medical staff, especially in consideration of the limited number of alternative therapies.

Cigarette smoking and appendectomy are risk factors for extraintestinal manifestations in ulcerative colitis.

OBJECTIVE: Two common factors, cigarette smoking and appendectomy, have been found to play a role in ulcerative colitis (UC). Data on their role in the development of extraintestinal manifestations (EIM) are scarce. METHODS: The relationship between cigarette smoking, appendectomy, and EIM was examined in a prospective study involving 535 (M/F = 319/216) consecutive UC patients followed up for 18 yr. We considered the major EIM: seronegative spondyloarthropathy, pyoderma gangrenosum/erythema nodosum, acute anterior uveitis, and primary sclerosing cholangitis. We excluded patients with a history of EIM or those colectomized before study entry, ex-smokers, and those who started to smoke during the course of UC. RESULTS: In UC patients, seronegative spondyloarthropathy and dermatologic complications were found increased in smokers (p < 0.0001; p = 0.001) or in subjects with appendectomy (p = 0.0003; p = 0.02), while acute anterior uveitis and primary sclerosing cholangitis did not differ. The Kaplan-Meier analysis showed 18-yr rates for EIM of 71% in smokers and 45% in nonsmokers (log-rank test, p = 0.0001), and of 85% in patients with appendectomy and 48% in those without (p = 0.0001). Cox proportional-hazard model showed that cigarette smoking and appendectomy are independent factors promoting EIM. In smokers with appendectomy the adjusted hazard ratio (3.197, 95% CI 1.529-6.684) was higher than in patients with appendectomy alone (2.617, 95% CI 1.542-4.442) or smoking alone (1.947, 95% CI 1.317-2.879). CONCLUSIONS: In UC patients, appendectomy and cigarette smoking are prognostic factors for the development of EIM. The unfavorable effect of cigarette smoking on EIM is additive to that of appendectomy.

Intraoperative radiochromoguided mapping of sentinel lymph node in colon cancer.

AIMS AND BACKGROUND: The aim of our study was to assess the feasibility of sentinel lymph node (SLN) detection in colon cancer using a radiochromoguided technique. The regional lymph node status is crucial for colorectal cancer staging and the stage of disease at the time of diagnosis is the main factor influencing therapeutic decision-making and patient survival. METHODS AND STUDY DESIGN: Between April and June 2001 eight patients with colon cancer were studied by radiochromoguided sentinel lymph node mapping. At the time of surgery 2 ml of patent blue dye was injected around the tumor, followed after 10 minutes by 2 ml of 99mTc-labeled albumin. After 30 minutes the SLN was identified by a gamma probe. Surgery was completed by standard resection. The SLN was processed for permanent hematoxylin and eosin staining and for immunohistochemical examination with anti-CEA and anti-cytokeratin antibodies. RESULTS: SLNs were identified in six patients; two were negative for metastasis by hematoxylin-eosin and immunohistochemical examination, two were positive for metastasis by both methods, and two were negative for metastasis by hematoxylin-eosin but positive by immunohistochemical examination. There were no false negative SLNs and no complications occurred. CONCLUSION: The actual utility of SLN detection for prognostic purposes is still unknown, but intraoperative radiochromoguided SLN mapping is technically feasible in colon cancer, although it is associated with more technical difficulties than in breast cancer and malignant melanoma.

[Polyembrioma of the testis: case report following chemotherapy for non-Hodgkin's lymphoma]. / Il poliembrioma del testicolo. Descrizione di un caso insorto dopo trattamento chemioterapico per linfoma non Hodgkin.

Testicular tumours represent 2% of all male malignancies, mostly concerning young men (20-40 years old). The polyembryoma is one of the uncommonest lesions and just recently it has been identified as autonomous nosographic entity. The reported case is peculiar because the patient was older than the most ones described in the literature and the tumour arose after polychemotherapy for non Hodgkins' disease. The Authors analyse some aspects concerning etiology, pathology and clinical approach to such rare neoplasm.

[Familial colonic polyposis: effect of molecular analysis on the diagnostic-therapeutic approach]. / Poliposi familiare del colon: influenza dell'analisi molecolare sull'approccio diagnostico-terapeutico.

Germline mutations of the Adenomatous polyposis gene (APC) are responsible for Familial Adenomatous Polyposis (FAP), an inherited condition that predisposes to the development of hundreds to thousands benign adenomas in the colo-rectum. If not surgically removed, they inevitably progress into malignant adenocarcinoma. To date more than 450 germline mutations have been described allowing the establishment of genotype/phenotype correlation between the site and type of molecular defects and their morbid consequences. Authors reviewed their experience concerning 22 FAP affected patients and their 26 first degree relatives, in whom the mutational analysis of the APC gene had been carried out. Site and type of mutations were associated with clinical parameters (age of onset, rectal involvement, extracolonic manifestations, presence of colorectal cancer) and treatments. The impact of mutational analyses on the clinical approach could be very interesting in the future, modifying both surveillance programs and therapeutical choices.
