RESUMO

BACKGROUND: Despite total thyroidectomy (TT) is the most practiced procedure for a preoperatively diagnosed neoplastic lesion, according to the ATA guidelines, many surgeons perform completion thyroidectomy (CT) after hemithyroidectomy for patients with preoperative follicular proliferation/indeterminate cytology who are diagnosed with malignancy. CT has a higher complication rate than the primary procedure. The primary endpoint of our study is to compare the morbidity rate after CT with that after primary TT in patients with follicular proliferation/indeterminate cytology. METHODS: We retrospectively reviewed 237 patients who underwent thyroid surgery from 2009 to 2018 at our institution. We recruited only patients with follicular proliferation/indeterminate cytology and excluded those undergoing lymphadenectomies and thyroidectomies for benign pathology and staged thyroidectomies after intraoperative documentation of a RLN lesion. One hundred eighty-six of these patients underwent TT, and fifty-one underwent CT for the detection of differentiated thyroid cancer at the histological exam. RESULTS: No differences were found in the total complication rates between the two groups (OR 0,76, 95% CI 0.35-1.65, P = 0.49). We did not find any significant differences in the subgroup analysis. In particular, no significant differences were identified for transient hypocalcaemia (OR 1.17, 95% CI 0.44-3.11; P = 0,74), permanent hypocalcaemia (OR 1.04, 95% CI 0.21-5.18; P = 0,95), transient unilateral recurrent laryngeal nerve palsy (OR 0.78, 95% CI 0.21-2.81; P = 0,16), permanent unilateral recurrent laryngeal nerve palsy (OR 1.48, 95% CI 0.28-7.85; P = 0,61), and haematoma (OR 1,84, 95% CI 0,16-20,71; P = 0,61). CONCLUSIONS: CT following hemithyroidectomy can be performed with acceptable morbidity in patients with thyroid nodules with preoperative indeterminate cytology/follicular proliferation.

RESUMO

Mast cells and macrophages can play a role in tumor angiogenesis by stimulating microvascular density (MVD). The density of mast cells positive to tryptase (MCDPT), tumor-associated macrophages (TAMs), and MVD were evaluated in a series of 86 gastric cancer (GC) tissue samples from patients who had undergone potential curative surgery. MCDPT, TAMs, and MVD were assessed in tumor tissue (TT) and in adjacent normal tissue (ANT) by immunohistochemistry and image analysis. Each of the above parameters was correlated with the others and, in particular for TT, with important clinico-pathological features. In TT, a significant correlation between MCDPT, TAMs, and MVD was found by Pearson t-test analysis (p ranged from 0.01 to 0.02). No correlation to the clinico-pathological features was found. A significant difference in terms of mean MCDPT, TAMs, and MVD between TT and ANT was found (p ranged from 0.001 to 0.002). Obtained data suggest MCDPT, TAMs, and MVD increased from ANT to TT. Interestingly, MCDPT and TAMs are linked in the tumor microenvironment and they play a role in GC angiogenesis in a synergistic manner. The assessment of the combination of MCDPT and TAMs could represent a surrogate marker of angiogenesis and could be evaluated as a target of novel anti-angiogenic therapies in GC patients.

RESUMO

Diabetic foot ulcerations may determine minor or major amputation, with a high impact on patients' life expectation and quality of life and on economic burden. Among minor amputations, transmetatarsal amputation (TMA) appears to be the most effective in terms of limb salvage rates and in maintaining foot and ankle biomechanics. In spite of this, TMA needs particular pre- and postoperative management in order to avoid the frequent failure rates. A systematic review was undertaken of studies concerning TMA and its care in diabetic foot gangrene. Studies were identified by searching the MEDLINE, Scopus and Science Direct databases until 13 January 2016. All studies were assessed using the Downs and Black quality checklist. Of the 348 records found, 86 matched our inclusion criteria. After reading the full-text articles, we decided to exclude 35 manuscripts because of the following reasons: (1) no innovative or important content, (2) no multivariable analysis, (3) insufficient data, (4) no clear potential biases or strategies to solve them, (5) no clear endpoints and (6) inconsistent or arbitrary conclusions. The final set included 51 articles. In the current literature, there are less data about TMA, indication for the selection of patients, outcomes and complications. Generally, the judgment of an experienced physician is one of the best indicators of subsequent healing. Ankle brachial indices, toe pressures, laser Doppler skin perfusion pressures, angiography and Doppler assessment of foot vasculature may help physicians in this decision. In any case, despite the presumed lower healing rate, it is reasonable to pursue a TMA in a patient with a higher likelihood of continued ambulation. Furthermore, tailored wound closure, adjuvant local treatments and the choice of the most appropriate antibiotic therapy, when infection occurs, are pivotal elements for the success of TMA procedures. TMA is a valuable option for diabetic foot gangrene that can prevent major limb loss and minimise loss of function, thus improving the quality of life for diabetic patients.

RESUMO

Tumour-associated macrophages (TAMs) represent pivotal components of tumour microenvironment promoting angiogenesis, tumour progression and invasion. In colorectal cancer (CRC), there are no conclusive data about the role of TAMs in angiogenesis-mediated tumour progression. In this study, we aimed to evaluate a correlation between TAMs, TAM immunostained area (TAMIA) microvascular density (MVD), endothelial area (EA) and cancer cells positive to VEGF-A (CCP-VEGF-A) in primary tumour tissue of locally advanced CRC patients undergone to radical surgery. A series of 76 patients with CRC were selected and evaluated by immunohistochemistry and image analysis. An anti-CD68 antibody was employed to assess TAMs and TAMIA expression, an anti-CD34 antibody was utilized to detect MVD and EA expression, whereas an anti-VEGF-A antibody was used to detect CCP-VEGF-A; then, tumour sections were evaluated by image analysis methods. The mean ± S.D. of TAMs, MVD and CCP-VEGF-A was 65.58 ± 21.14, 28.53 ± 7.75 and 63% ± 37%, respectively; the mean ± S.D. of TAMIA and EA was 438.37 ± 124.14µ(2) and 186.73 ± 67.22µ(2) , respectively. A significant correlation was found between TAMs, TAMIA, MVD and EA each other (r ranging from 0.69 to 0.84; P ranging from 0.000 to 0.004). The high level of expression of TAMs and TAMIA in tumour tissue and the significant correlation with both MVD and EA illustrate that TAMs could represent a marker that plays an important role in promoting angiogenesis-mediated CRC. In this context, novel agents killing TAMs might be evaluated in clinical trials as a new anti-angiogenic approach.

RESUMO

INTRODUCTION: Smartphones changed the method by which doctors communicate with each other, offer modern functionalities sensitive to the context of use, and can represent a valuable ally in the healthcare system. Studies have shown that WhatsApp™ application can facilitate communication within the healthcare team and provide the attending physician a constant oversight of activities performed by junior team members. The aim of the study was to use WhatsApp between two distant surgical teams involved in a program of elective surgery to verify if it facilitates communication, enhances learning, and improves patient care preserving their privacy. METHODS: We conducted a focused group of surgeons over a 28-month period (from March 2013 to July 2015), and from September 2014 to July 2015, a group of selected specialists communicated healthcare matters through the newly founded "WhatsApp Surgery Group." Each patient enrolled in the study signed a consent form to let the team communicate his/her clinical data using WhatsApp. Communication between team members, response times, and types of messages were evaluated. RESULTS: Forty six (n = 46) patients were enrolled in the study. A total of 1,053 images were used with an average of 78 images for each patient (range 41-143). 125 h of communication were recorded, generating 354 communication events. The expert surgeon had received the highest number of questions (P, 0.001), while the residents asked clinical questions (P, 0.001) and were the fastest responders to communications (P, 0.001). CONCLUSION: Our study investigated how two distant clinical teams may exploit such a communication system and quantifies both the direction and type of communication between surgeons. WhatsApp is a low cost, secure, and fast technology and it offers the opportunity to facilitate clinical and nonclinical communications, enhance learning, and improve patient care preserving their privacy.

RESUMO

Mast cells (MCs) are cells that originate in the bone marrow from pluripotent CD34+ hematopoietic stem cells. Precursors of MCs migrate through the circulation to their target tissues, completing their maturation process into granulated cells under the influence of several microenvironment growth factors. The most important of these factors is the ligand for the c-Kit receptor (c-Kit-R) namely stem cell factor (SCF), secreted mainly by fibroblasts and endothelial cells (ECs). SCF also regulates development, survival and de novo proliferation of MCs. It has already been demonstrated that gain-of-function mutations of gene c-Kit encoding c-Kit-R result in the development of some tumors. Furthermore, MCs are able also to modulate both innate and adaptive immune response and to express the high-affinity IgE receptor following IgE activation. Among the other IgE-independent MC activation mechanisms, a wide variety of other surface receptors for cytokines, chemokines, immunoglobulins, and complement are also described. Interestingly, MCs can stimulate angiogenesis by releasing of several pro-angiogenic cytokines stored in their cytoplasm. Studies published in the last year suggest that angiogenesis stimulated by MCs may play an important role in tumor growth and progression. Here, we aim to focus several biological features of MCs and to summarize new anti-cancer MC-targeted strategies with potential translation in human clinical trials.

RESUMO

Mast Cells (MCs) play a role in immune responses and more recently MCs have been involved in tumoral angiogenesis. In particular MCs can release tryptase, a potent in vivo and in vitro pro-angiogenic factor via proteinase-activated receptor-2 (PAR-2) activation and mitogen-activated protein kinase (MAPK) phosphorylation. MCs can release tryptase following c-Kit receptor activation. Nevertheless, no data are available concerning the relationship among MCs Density Positive to Tryptase (MCDPT) and Microvascular Density (MVD) in both primary gastric cancer tissue and loco-regional lymph node metastases. A series of 75 GC patients with stage T2-3N2-3M0 (by AJCC for Gastric Cancer Seventh Edition) undergone to radical surgery were selected for the study. MCDPT and MVD were evaluated by immunohistochemistry and by image analysis system and results were correlated each to other in primary tumor tissue and in metastatic lymph nodes harvested. Furthermore, tissue parameters were correlated with important clinico-pathological features. A significant correlation between MCDPT and MVD was found in primary gastric cancer tissue and lymph node metastases. Pearson t-test analysis (r ranged from 0.74 to 0.79; p-value ranged from 0.001 to 0.003). These preliminary data suggest that MCDPT play a role in angiogenesis in both primary tumor and in lymph node metastases from GC. We suggest that MCs and tryptase could be further evaluated as novel targets for anti-angiogenic therapies.

RESUMO

While gastric cancer is a well established angiogenesis driven tumor, no data has been published regarding angiogenesis stimulated by mast cells (MCs) positive for tryptase in bone metastases from gastric cancer patients (BMGCP). It is well established that MCs play a role in immune responses and more recently it was demonstrated that MCs have been involved in tumor angiogenesis. We analyzed infiltrating MCs and neovascularization in BMGCP diagnosed by histology. A series of 15 stage T3-4N2-3M1 (by AJCC for Gastric Cancer Staging 7th Edition) BMGCP from bone biopsies were selected. Tumour tissue samples were evaluated by mean of immunohistochemistry and image analysis methods in terms of MCs density positive to tryptase (MCDPT), MCs area positive to tryptase (MCAPT), microvascular density (MVD) and endothelial area (EA). A significant correlation between MCDPT, MCAPT, MVD and EA groups to each other was found by Pearson and t-test analysis (r ranged from 0.68 to 0.82; p-value ranged from 0.00 to 0.02). Our very preliminary data suggest that infiltrating MCs positive for tryptase may play a role in BMGCP angiogenesis, and could be further evaluated as a novel target of anti-angiogenic therapy.

RESUMO

Colorectal cancer is one of the leading causes of death due to cancer worldwide. Therefore, the identification of high-specificity and -sensitivity biomarkers for the early detection of colorectal cancer is urgently needed. Post-translational modifications, such as glycosylation, are known to play an important role in cancer progression. In the present work, we used a quantitative proteomic technique based on (18)O stable isotope labeling to identify differentially expressed N-linked glycoproteins in colorectal cancer tissue samples compared with healthy colorectal tissue from 19 patients undergoing colorectal cancer surgery. We identified 54 up-regulated glycoproteins in colorectal cancer samples, therefore potentially involved in the biological processes of tumorigenesis. In particular, nine of these (PLOD2, DPEP1, SE1L1, CD82, PAR1, PLOD3, S12A2, LAMP3, OLFM4) were found to be up-regulated in the great majority of the cohort, and, interestingly, the association with colorectal cancer of four (PLOD2, S12A2, PLOD3, CD82) has not been hitherto described.

RESUMO

BACKGROUND: Tryptase is a serine protease released from mast cells that plays a role in tumor angiogenesis. In this study we aimed to evaluate serum tryptase levels in 105 female early breast cancer patients before (STLBS) and after (STLAS) radical surgical resection, mast cell density positive to tryptase (MCDPT) and microvascular density (MVD). METHODS: STLBS and STLAS were assessed using the UniCAP Tryptase Fluoroenzyme immunoassay. Tumor sections were immunostained with a primary anti-tryptase antibody and an anti-CD-34 antibody by means of immunohistochemistry. RESULTS: The mean ± 1 standard deviation STLBS and STLAS was 7.18 ± 2.63 µg/L, and 5.13 ± 2.21 respectively and a significant difference between mean levels was found (p = 0.0001) by student t-test. A strong correlation between STLBS and MVD (r = 0.81, p = 0.0001); STLBS and MCDPT (r = 0.69, p = 0.003); and MCDPT and MVD (r = 0.77; p = 0.0001) was found. CONCLUSIONS: Results demonstrated higher STLBS in breast cancer patients, indicating an involvement of MC tryptase in breast cancer angiogenesis. Therefore, serum tryptase levels may play a role as a novel surrogate angiogenic marker predictive of response to radical surgery in breast cancer patients. In this patients setting, it's intriguing to hypothesize that tryptase inhibitors might be evaluated in clinical trials.

RESUMO

Between the Ninth International Gastric Cancer Congress (IGCC) in South-Korea (Seoul, 2011) and the Tenth IGCC in Italy (Verona, 2013), the Insubria University organized the First International Course on Upper Gastrointestinal Surgery (Varese, December 2, 2011), with the patronage of Italian Research Group for Gastric Cancer (IRGGC) and the International Gastric Cancer Association (IGCA). The Course was intended to be a comprehensive update and review on advanced gastric cancer (GC) staging and treatment from well-known international experts. Clinical, research, and educational aspects of the surgeon's role in the era of stage-adapted therapy were discussed. As highlighted in the meeting, in this final document we summarize and thoroughly analyze (with references only for well-acquired randomized control trials) the new and old open problems in surgical management of advanced GC. Between the Ninth (Seoul, 2011) and the Tenth (Verona,2013) International Gastric Cancer Congress, the First International Course on Upper Gastrointestinal Surgery (Varese, December 2, 2011) was organized by the University of Insubria. This congress received the patronage of the International Gastric Cancer Association and the Italian Research Group for Gastric Cancer. The aim was to discuss open issues in surgical management of advanced gastric malignancies. We considered the opinions of several recognized experts in the field from both the Eastern and Western world, focused on definition problems and oncological and technical issues to define the current principles of advanced gastric cancer (GC) surgery.

RESUMO

BACKGROUND: Angiogenesis has been found to be a reliable prognostic indicator for several types of malignancies. Tryptase is a serine protease stored in mast cell (MC) granules, which plays a role in tumor angiogenesis. MCs can release tryptase following c-Kit receptor activation. METHOD: In this study, immunohistochemistry, image analysis methods and clinical aspects were employed in a series of 41 gastrointestinal cancer patients with stage T3-4N2a-bM0 (by the American Joint Committee on Cancer, AJCC, for colorectal cancer, 7th edition) and T3N2-3M0 (by AJCC for gastric cancer, 7th edition) to evaluate the possible correlation between MCs positive to tryptase (MCPT) in tumor tissue and the number of metastatic lymph nodes harvested. RESULTS: Data demonstrated a positive correlation between MCPT in tumor tissue and the number of metastatic lymph nodes; the validity of these data needs confirmation in larger patient cohorts. CONCLUSION: This is the first report considering MCPT in tumor tissue as a potential tool for a valid indication of the type of surgical treatment and its radicality, and it might be considered for the prognosis of patients before radical surgical treatment. Our pilot data need confirmation in a larger patient cohort.

RESUMO

In recent years, laparoendoscopic single-site surgery (LESS) has gained greater interest and diffusion for the treatment of gallstones. This critical review aims to evaluate the feasibility and safety of LESS cholecystectomy versus the 3-port technique (TPT) through a comparative analysis of 5 parameters: mean operative time, intraoperative and postoperative complications, conversion to open, conversion to the 4-trocar technique and postoperative hospital stay. The authors performed a systematic search of the medical literature through a search of PubMed and Ovid EMBASE. Inclusion criteria were as follows: publication date between January 1, 2005, and December 31, 2010; English or Italian language; human participants and series of 20 operations or more. There were 5 manuscripts meeting the inclusion criteria for TPT and 23 for LESS. Only one prospective randomized controlled trial comparing TPT and LESS was identified. Operative time is significantly longer in the single-incision group. Complications and conversion rates to the 4-port technique are higher in LESS. Postoperative hospital stay is similar in the 2 groups. Rate of conversion to open is higher in TPT. Despite the number of publications on LESS cholecystectomy, the vast majority of data available in the literature are from small case series without any comparative data. Although LESS cholecystectomy is a fashionable technique there are few data available for an evidence-based determination as to the real benefits of this technique. Well-designed comparative studies are suggested to validate the clinical benefits and ensure that there are no new complications or added costs associated with the new technique.

RESUMO

AIM: Reporting our experience with NIM-response 2.0 and 3.0 system in a series of 127 thyroidectomies. MATERIALS OF STUDY: 127 patients were operated at the "Magna Graecia" University (Catanzaro) from 2009 September to 2010 December, using the technique of IntraOperative NeuroMonitoring (IONM). For each patient the surgeon charge filled in a "questionnaire" assessing his/her compliance with the apparatus. RESULTS: We report 0.8% permanent and 0.4% transient recurrent laryngeal nerve paralysis. All surgeons have been fully satisfied from IONM technique. DISCUSSION: A recurrent laryngeal nerve lesion may occur in patients operated on total thyroidectomy between 5-8% for transient palsies and 1-3% for the permanent ones. The use of IONM seems to contribute to a reduction of transient paralysis, even if this method is still not widely accepted Nevertheless the compliance of the surgeons with IONM seems to develop very highly. CONCLUSIONS: NIM-response is helpful in protecting recurrent laryngeal nerve function. Advantages were observed in reduction of postoperative dysphonia and in improving the surgeon's confidence in performing a total thyroidectomy.

RESUMO

A rare case of Solitary fibrous tumor (SFT) of the pelvis is reported. A 76-years-old man presented with a low abdominal pain, acute urine retention and constipation. Imaging studies (US, CT MR) showed an 17 x 10 x 9 ovoid mass in the pelvis, dislocating bladder and rectum. Finally, trans-rectal needle biopsy suggested the diagnosis of SFT. En bloc excision of tumor and rectum (because of strong adhesions) was performed. Histological examination showed spindle and fibroblastic-like cells dispersed in collagenous areas with positive stains for CD34, bcl-2, CD99 and it confirmed diagnosis of SFT. No postoperative complications occurred, only vesico-sphincter dyssynergia was found by urodynamics. After 5 years, patient is disease-free. SFT is, usually, benign tumor with slow growth and excellent prognosis. Complete surgical resection is the only curative treatment. However, 10-15% of SFT are malignant and histological findings cannot always predict clinical behaviour. For this reason, careful and long term follow-up is necessary after surgery.

RESUMO

BACKGROUND: Colorectal cancer (CRC) is one of the leading cause of cancer deaths worldwide. The aetiology of CRC is complex and involves interaction on environmental and genetic factors. The two most important pathways are the EGFR (Epidermal Grow Factor Receptor) signaling pathway, with the involvement of KRAS and BRAF, and the DNA mismatch repair (MMR). Generally, KRAS and BRAF mutations are mutually exclusive. They are both able to cause RAS/RAF/MAPK signaling pathway upregulation and are necessary for CRC development. BRAF mutations confers a poor prognosis in Western CRC patients, particularly in metastatic CRC (mCRC) and its mutations occur in approximately 4-20% CRC, with the vast majority being the V600E hotspot mutation. KRAS mutations are observed in 30- 40% CRC patients and act as predictive markers of resistance to epidermal growth factor receptor (EGFR)-targeted antibodies in metastatic CRC. Initial patient management is defined by TNM stage at diagnosis but in patient with stage II and III CRC, TNM staging alone does not predict outcome in CRC patients who may be eligible for adjuvant chemotherapy. Furthermore, for stage II and III, non-metastatic CRC patients, the prognostic role of BRAF and KRAS mutations is still controversial, particularly comparing microsatellite-unstable (MSI) and - stable tumors (MSS). The aim of this study was to clarify the impact of KRAS/BRAF mutations on prognosis in patients with stage I-III CRC. MATERIALS AND METHODS: A systematic review of literature was undertaken to evaluate the prognostic value of KRAS and BRAF mutations in stage I-III colorectal cancer. Four major databases (PUBMED, EMBASE, WEB OF SCIENCE and COCHRANE LIBRARY) were searched. RESULTS: Ninety-two studies were identified. After screening of titles, abstract and inclusion criteria sixteen articles were included. Of the selected articles, five were prospective, ten were retrospectives studies, and one was a combined retrospective/ prospective study. CONCLUSION: In our opinion, a combination of molecular markers, tumor location with the other clinical-pathological variables and microsatellite status is essential to have a correct prognosis. Nevertheless, this combination could be useful as a predictive factor in stage I-III CRC. KEY WORDS: BRAF, Colorectal Cancer, KRAS, Stage I-III CRC, Translational research.

RESUMO

BACKGROUND: Colorectal cancer is one of the most common invasive cancers, and it is responsible for considerable physical and psychosocial morbidity specially in older patients. However, only few reports focused on quality of life, cost-effectiveness and clinical outcomes of rectal cancer patients undergone to surgery. This retrospective study compares short-term and long-term outcomes in rectal cancer patients with more and less than 75 years of age. METHODS: Four hundred consecutive patients underwent radical surgery for rectal adenocarcinoma and they were collected in a prospective institutional database and divided into two groups: group 1 (≥75 years, N.=98); group 2 (<75 years, N.=302). Rectal anterior resection (RAR) with sphincter-saving restorative proctectomy and with application of silicone transanal tube NO COIL® 60-80 mm long, was the only procedure considered. Main clinical and pathological data were assessed and compared. RESULTS: Statistically significant differences between the two groups were detected regard to comorbidities and the emergency presentation. Overall survival is lower in patients over 75 age, but cancer-related survival is not different between the two groups. CONCLUSIONS: Although advanced age is associated with higher morbidity and mortality, in our experience, itself is not a contraindication for surgical sphincter-saving proctetomy in rectal cancer patients. The absence of a stoma also improved the cost effectiveness and patients' quality of life in both groups: psychological morbidity, sexuality, levels of anxiety and depression, body image.

RESUMO

Colorectal cancer is locally advanced in 10-20% of cases. In these cases the surgical procedure of multivisceral resection is used in an attempt to obtain a curative result. The aim of the present study was to assess survival and biological humoral and clinical factors in patients subjected to multivisceral resection in our surgical unit. Fifteen patients affected by advanced colorectal cancer (T4) subjected to multivisceral resection are compared with a population of 19 patients subjected to standard resection for Dukes B and C colorectal cancer. We analysed three-year survival and the associated clinical, humoral and biological factors. Survival analysis was done using Kaplan-Meyer curves. The three-year survival rate was 33% in patients subjected to multivisceral resection. Post-surgical mortality (< 30 days) was 6.6%. Longer surgical times, a greater number of transfusions and high values of CEA, CA 19.9, and total bilirubin are statistically associated with the group of patients subjected to multivisceral resection. In advanced colorectal cancer multivisceral resection appears to be a legitimate procedure in order to obtain presumed oncological radicality. The identification of predictive factors can select patients most likely to benefit from multivisceral resection.

RESUMO

Bochdalek diaphragmatic hernia usually begins during childhood, but may be an occasional finding even in adults. The treatment of choice is surgical repair to avoid herniated bowel complications. The operation often requires a combined approach consisting in thoracotomy and laparotomy. This is a convenient solution to eliminate the vascular risks (if there are additional concomitant embryonic defects, such as intestinal malrotation). We report a case of a female, aged 45 years, with epigastric cramp-like pain for 4 days and tenderness in the right abdominal quadrants during physical examination; the standard laboratory data showed decreased blood levels of calcium and potassium. Chest and abdominal X-rays revealed significant, widespread colic distension and the presence of a colic loop in the chest. We confirmed these results by CT and barium enema and proceeded with urgent surgery consisting in a right hemicolectomy (extended as far as the left part of the tranverse colon) for volvulus and with stitching of the diaphragmatic gap. We also discovered incomplete intestinal malrotation. After surgery, complete remission of the clinical symptoms was achieved. This case report demonstrates that, despite the apparent clinical silence, congenital diaphragmatic hernia in an adult may often manifest itself with particular gravity calling for urgent surgery.

RESUMO

BACKGROUND: Obesity is a debilitating growing condition and represents a challenge for every surgeon. It is associated with the activation of the inflammatory pathway and this may have a negative impact on the natural history of some rheumatic diseases. Bariatric surgery, reducing obesity, could bring to a minor activation of the well-known inflammatory pathway with improvement of these diseases. The aim of this review is to investigate the role of weight loss, achieved through bariatric surgery, in rheumatic diseases. MATERIALS AND METHODS: A systematic review of literature was undertaken to evaluate weight loss subsequent to bariatric surgery in obese patients suffering from some rheumatic diseases (Rheumatoid Arthritis, Psoriasis, Psoriatic Arthritis, Fibromyalgia, Osteoarthritis, Systemic Lupus Erythematous). Three major databases (PUBMED, EMBASE and WEB OF SCIENCE) were searched. RESULTS: Three-hundred studies were identified. After screening of titles, abstracts and inclusion criteria sixteen articles were included. Of the selected articles, seven were reviews, five were case reports, one was a clinical report, one was a retrospective study, one was a cohort study and one was an author manuscript. CONCLUSION: Weight loss, obtained through bariatric surgery, seems to reduce serum inflammatory markers as a consequence of the inflammatory pathway reduction and this is connected with both the improvement of some rheumatic diseases as well as with the reduction in the use of medicaments (steroids and immunosuppressors).
