The Role of Helicobacter Pylori Infection in the Development of Gastric Cancer - Review of the Literature.

Helicobacter pylori (H. pylori), classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC), is linked to gastric cancer. The progression from atrophy to metaplasia, dysplasia, and carcinoma constitutes the pathway for intestinal-type gastric carcinoma development. H. pylori infection significantly increases gastric cancer risk, particularly in individuals with atrophic gastritis. Virulence factors like CagA and VacA disrupt host signaling pathways, contributing to chronic inflammation and carcinogenesis. Pro-inflammatory cytokines and dysregulated tumor suppressor genes further fuel this process. Eradicating H. pylori reduces gastric cancer incidence, especially in patients with atrophic gastritis and/or intestinal metaplasia. However, it may not prevent cancer in those with advanced pre-neoplastic lesions. Early detection and management of H. pylori infection are crucial in mitigating gastric cancer risk, offering significant benefits.

The Vascularized Omentum Lymph Node Transfer - A Key Point in the Lymphedema Management.

Background: As an increased number of women beat breast cancer worldwide, the breast cancer related lymphedema has gained more attention recently. The vascularized omentum lymph node transfer has been approached as an useful tool for advanced and recurrent cases. The purpose of the paper is to emphasize the advantages and disadvantages of this method. Materials and Methods: This retrospective study consists of 17 patients known with breast cancer related lymphedema who received vascularized omentum lymph node transfer. Data was recorded between January 2022 and January 2023. Patients diagnosed with secondary lymphedema stage II or III, unresponsive to previous microsurgical lymphovenous bypass were included. Results: The most prevalent affected site was the left upper limb (59%), where edema was mainly identified in the forearm (75%). Nevertheless, more than half of the subjects have previously received lymphaticovenous anastomosis. The correlation between the stage of lymphedema and the postoperative reduction of the volume of the affected limb was -0.26, the slope to reached -0.33, with an intercept value of 2.64. The follow-up period showed reduced upper limb volume and an improved quality of life. Conclusion: Through an experienced hand, this versatile flap brings hope to breast cancer survivors with lymphedema.

Helicobacter pylori Infection at Crossroads between Specialties.

Background: Helicobacter pylori (H. pylori) infection is one of the major current public health problems, its incidence being high worldwide. This condition is associated with other pathologies such as peptic ulcer or gastric cancer, causing a real challenge for specialists in the medical field. Methods:We conducted a retrospective study that includes a cohort of 275 patients who performed EGD and were tested for the presence of H. pylori by the stool antigen test, between July 2022 and December 2023. Results:The cohort had an average age of 62.79 ± 13.8 years old, with a male predominance 156 patients (56.7%) and the most frequent lesion is antral gastritis (149 cases, 54.2%). Gastric ulcer in those with positive tests in H. pylori had a double incidence compared to those in which the infection is not present (19.7% vs. 9.2%, p=0.012). Conclusions:: H. pylori infection still remains a condition that can be complicated by various pathological conditions that can evolve from a slight erosion of the gastric mucosa to digestive neoplasia that require complex multidisciplinary treatments, which is why understanding the mechanisms and applying therapeutic resources as soon as possible is essential.

Extracranial Facial Nerve Schwannoma-Histological Surprise or Therapeutic Planning?

Schwannomas (neurilemomas) are benign, slow-growing, encapsulated, white, yellow, or pink tumors originating in Schwann cells in the sheaths of cranial nerves or myelinated peripheral nerves. Facial nerve schwannomas (FNS) can form anywhere along the course of the nerve, from the pontocerebellar angle to the terminal branches of the facial nerve. In this article, we propose a review of the specialized literature regarding the diagnostic and therapeutic management of schwannomas of the extracranial segment of the facial nerve, also presenting our experience in this type of rare neurogenic tumor. The clinical exam reveals pretragial swelling or retromandibular swelling, the extrinsic compression of the lateral oropharyngeal wall like a parapharyngeal tumor. The function of the facial nerve is generally preserved due to the eccentric growth of the tumor pushing on the nerve fibers, and the incidence of peripheral facial paralysis in FNSs is described in 20-27% of cases. Magnetic Resonance Imaging (MRI) examination is the gold standard and describes a mass with iso signal to muscle on T1 and hyper signal to muscle on T2 and a characteristic "darts sign." The most practical differential diagnoses are pleomorphic adenoma of the parotid gland and glossopharyngeal schwannoma. The surgical approach to FNSs requires an experienced surgeon, and radical ablation by extracapsular dissection with preservation of the facial nerve is the gold standard for the cure. The patient's informed consent is important regarding the diagnosis of schwannoma and the possibility of facial nerve resection with reconstruction. Frozen section intraoperative examination is necessary to rule out malignancy or when sectioning of the facial nerve fibers is necessary. Alternative therapeutic strategies are imaging monitoring or stereotactic radiosurgery. The main factors which are considered during the management are the extension of the tumor, the presence or not of facial palsy, the experience of the surgeon, and the patient's options.

Recent Advances and Adaptive Strategies in Image Guidance for Cervical Cancer Radiotherapy.

The standard of care for locally advanced cervical cancer is external beam radiotherapy (EBRT) with simultaneous chemotherapy followed by an internal radiation boost. New imaging methods such as positron-emission tomography and magnetic resonance imaging have been implemented into daily practice for better tumor delineation in radiotherapy planning. The method of delivering radiation has changed with technical advances in qualitative imaging and treatment delivery. Image-guided radiotherapy (IGRT) plays an important role in minimizing treatment toxicity of pelvic radiation and provides a superior conformality for sparing the organs at risk (OARs) such as bone marrow, bowel, rectum, and bladder. Similarly, three-dimensional image-guided adaptive brachytherapy (3D-IGABT) with computed tomography (CT) or magnetic resonance imaging (MRI) has been reported to improve target coverage and reduce the dose to normal tissues. Brachytherapy is a complementary part of radiotherapy treatment for cervical cancer and, over the past 20 years, 3D-image-based brachytherapy has rapidly evolved and established itself as the gold standard. With new techniques and adaptive treatment in cervical cancer, the concept of personalized medicine is introduced with an enhanced comprehension of the therapeutic index not only in terms of volume (three-dimensional) but during treatment too (four-dimensional). Current data show promising results with integrated IGRT and IGABT in clinical practice and, therefore, better local control and overall survival while reducing treatment-related morbidity. This review gives an overview of the substantial impact that occurred in the progress of image-guided adaptive external beam radiotherapy and brachytherapy.

Identification of Predictive Factors for Pathologic Complete Response in Rectal Cancer Patients Undergoing Neoadjuvant Treatment: A Retrospective Study.

Background: Colorectal cancer is a serious illness, with rectal cancer accounting for thirty percent of all cases. For patients diagnosed with rectal cancer, neoadjuvant downstaging chemoradiotherapy is often necessary due to advanced disease at presentation. However, for certain patients, neoadjuvant chemotherapy can result in a complete response, leading to the possibility of overtreatment during subsequent definitive surgery. Methods: In order to identify predictors for clinical or pathologic complete response, we conducted a retrospective study on 231 patients diagnosed with locally advanced rectal cancer who underwent neoadjuvant treatment. Results: Our results indicate that tumor characteristics remain the primary predictive factors for treatment response in rectal cancer patients. Specifically, we found that a complete pathologic response was more likely in patients with stage I/II disease compared to stage III/IV. However, we did not identify any statistically significant associations between radiotherapy characteristics (such as fractionation, treatment technique or total dose) and complete response rates. Conclusions: In conclusion, our study highlights the importance of tumor stage in predicting pathologic complete response following neoadjuvant chemoradiotherapy for rectal cancer patients. Other clinical and pathologic factors, such as tumor size, may also be important predictors of treatment response and should be explored in future studies.

What Is Different in Acute Hematologic Malignancy-Associated ARDS? An Overview of the Literature.

Background and Objectives: Acute hematologic malignancies are a group of heterogeneous blood diseases with a high mortality rate, mostly due to acute respiratory failure (ARF). Acute respiratory distress syndrome (ARDS) is one form of ARF which represents a challenging clinical condition. The paper aims to review current knowledge regarding the variable pathogenic mechanisms, as well as therapeutic options for ARDS in acute hematologic malignancy patients. Data collection: We provide an overview of ARDS in patients with acute hematologic malignancy, from an etiologic perspective. We searched databases such as PubMed or Google Scholar, including articles published until June 2022, using the following keywords: ARDS in hematologic malignancy, pneumonia in hematologic malignancy, drug-induced ARDS, leukostasis, pulmonary leukemic infiltration, pulmonary lysis syndrome, engraftment syndrome, diffuse alveolar hemorrhage, TRALI in hematologic malignancy, hematopoietic stem cell transplant ARDS, radiation pneumonitis. We included relevant research articles, case reports, and reviews published in the last 18 years. Results: The main causes of ARDS in acute hematologic malignancy are: pneumonia-associated ARDS, leukostasis, leukemic infiltration of the lung, pulmonary lysis syndrome, drug-induced ARDS, radiotherapy-induced ARDS, diffuse alveolar hemorrhage, peri-engraftment respiratory distress syndrome, hematopoietic stem cell transplantation-related ARDS, transfusion-related acute lung injury. Conclusions: The short-term prognosis of ARDS in acute hematologic malignancy relies on prompt diagnosis and treatment. Due to its etiological heterogeneity, precision-based strategies should be used to improve overall survival. Future studies should focus on identifying the relevance of such etiologic-based diagnostic strategies in ARDS secondary to acute hematologic malignancy.

Mesenteric Ischemia in a Patient with Essential Thrombocythemia: Does COVID-19 Play Any Role? A Case Report and Overview of the Literature.

INTRODUCTION: Chronic mesenteric ischemia is a rare entity with non-specific symptomatology; combined with rare etiologies, it could lead to unwarranted surgical indication. CASE REPORT: We report the case of an 85-year-old woman, with a history of hypertension, persistent thrombocytosis, atherosclerosis, and recent minor COVID-19 infection, presenting to the hospital with postprandial abdominal pain and nonspecific clinical examination findings; upon abdominal CT, superior mesenteric artery circumferential thrombosis was revealed. A bone marrow biopsy was performed due to suspected essential thrombocythemia, confirming the diagnosis. An endovascular approach was chosen as therapy option and a stent was placed in the occluded area. Dual antiplatelet and cytoreductive therapies were initiated after the intervention. Clinical course was excellent, with no residual stenosis 1 month after stenting. CONCLUSIONS: The therapeutic strategy in elderly patients with exacerbated chronic mesenteric ischemia requires an interdisciplinary approach in solving both the exacerbation and the underlying conditions in order to prevent further thrombotic events. Although the patient presented a thrombotic state, other specific risk factors such as COVID-19 related-coagulopathy and essential thrombocythemia should be considered.

Transposition Flaps in the Reconstruction of Auricular Defects after MOHS Micrographic Surgery.

Background: Closing of ear defects can be a significant surgical challenge, due to the complex three-dimensional cartilaginous structure of this region. Patients and Results: We present a series of 5 retrospective cases of defects on the ear, left after Mohs micrographic surgery for skin cancer, that were repaired with transposition flaps and their Discussions and Conclusion: There are various surgical procedures described for the reconstruction of an ear defect, including local flaps, skin grafts, and even healing by secondary intention. In our opinion, transposition flaps can be a good option when dealing with defects of the tragus, chonca, triangular fossa, superior part of the helix, or even the medial part of the ear. It allows for reconstruction in a single surgical step with decreased morbidity and favorable cosmetic results.

Achalasia at the Crossroads Between Specialties.

Background: Achalasia is a condition that can be treated either by surgery, such as Heller myotomy associated with an antireflux procedure, or by pneumatic dilation, the choice of type of treatment being a widely debated topic nowadays. Methods: We selected patients with the diagnosis of achalasia, calculating the Eckardt score on admission and they were treated by pneumatic dilation, respectively by myotomy associated with fundoplication. Therapeutic success at the end of treatment was analyzed, as well as that in subsequent follow-ups. At the same time, other important aspects of the study were quality of life and complications. Results: Forty-eight patients were included, 20 in the group of those treated by pneumatic dilation, and 28 treated by surgery. The results of the therapeutic success were to the advantage of the surgery, both after the completion of the treatment, and in the follow-ups from one year to 2 years (96.4% vs 90%, respectively 92.9% vs. 85%). The quality of life was better in patients with pneumatic dilation throughout the period. Conclusions: Surgical treatment of achalasia has a higher success rate than pneumatic dilation, but the latter is associated with a better quality of life.

Inguinal Hernia - Is There Any Room Left for Classical Procedures?

Background: Nowadays, the repair of inguinal hernias is mostly achieved through a minimally invasive approach (TAPP or TEP) which has well-known advantages. However, the Lichtenstein mesh technique still has some particular indications. Methods: We reviewed 256 consecutive patients who underwent a Lichtenstein procedure during 5 years (2015-2019) in the Department of General Surgery of "Dr. I. Cantacuzino" Clinical Hospital. The vast majority of them - 180 (74%) were 60 or older and 105 (41%) were over 70. Severe cardiovascular diseases, diabetes mellitus and other significant co-morbidities were recorded in 128 patients (50%). Results: 240 patients had a favorable evolution, 12 experienced local complications, while in 4 we recorded severe cardiac post-operative events.1 patient died due to a massive myocardial infarction. Conclusions: The surgical treatment of inguinal hernias should be adapted to the age and biological status of the patient; surgical departments must be able to provide both a laparoscopic and an open-surgery approach.

Identifying the Sentinel Lymph Node in Patients with Cutaneous Melanoma - Preliminary Report of a Private Clinic in Bucharest.

Background: The accuracy of the staging, along with the reproductibility of intraoperative lymph car-tography, and lymph node biopsy in patients with malignant melanoma was unanimously validated in the last decade. This technique allows the discovery of lymph node micrometastses with the help of immunohistochemical methods. The goal of the present study is to present the experience of our clinic in identification and biopsy protocol of the lymph node. Methods: A year-long retrospective analysis was running between March 2019 - December 2019 con-cerning 57 patients with cutaneous melanoma on which detection and excisional biopsy of the lymph node was performed. The procedure was performed by the double method using vital dye and a ra-dio-active tracer. Demographic information was filed, as well as data on location of primary tumors, tumor histology, and radioactivity level. Results: The mean Breslow thickness of primary skin melanomas was 2.7 mm. At least one lymph node was identified in 56 of the 57 patients included in the study. Among those, 15 (26%) had at least one metastatic node. The mean number of excised lymph nodes per patient was 1.6. Conclusions: The cartography and biopsy of lymph nodes need the involvement of a complex multi disciplinary team made of nuclear medicine, surgery, and anatomopathology specialists. This way one provides both a correct staging of the patient with melanoma and access to adjuvant innovative therapies, thus considerably improving the prognosis.

Surgical Outcomes of More Than 1300 Cases of Mohs Micrographic Surgeries from a Private Mohs Clinic in Romania.

Background: Basal cell carcinoma (BCC) and Squamous cell carcinoma (SCC) are the most frequent skin cancers with a continuous increasing incidence and a cause of economic impact. Mohs micrographic surgery (MMS) is known as the gold-standard of treatment of non-melanoma skin cancer. Methods: The files of the patients treated with MMS were analysed during a 6 year period (2014-2019) and demographic information was extracted in addition to the information on tumor histology, localization of tumors, number of stages required for a complete removal of the tumors, and the evolution of the patients. We also analysed the information regarding the number and type of reconstructions performed. Results: Over the course of 6 years, 1,356 cutaneous tumors were treated in our clinic by means of MMS. BCC represented 80.5%, SCC 17.6%, and other tumors such as melanoma in situ, DFSP, Extramammary Paget's Disease - being 1.9% of the number of other treated tumors. During the period under review, only 4 cases of post-Mohs Micrographic Surgery recurrence have been recorded, with a cure rate of over 99.7%. Conclusions: Mohs micrographic surgery is an efficient treatment method in removing cutaneous carcinoma as well as tumors with special indications with a low recurrence rate therefore reducing the need of successive surgical interventions.

Skin Grafting in the Treatment of Diabetic Foot Soft Tissue Defects.

Background: According to the World Health Organization, cases of diabetes have risen from 108 million in 1980 to 422 million in 2014, with a more rapid rising in middle- and low-income countries. Diabetes causes yearly approximately 1.6 million deaths, and is a major cause of heart attacks, stroke, kidney failure, blindness and lower limb amputation. This article provides information on the treatment of a frequent complication related to diabetes, namely toe/ partial foot amputation. Broad, deep operative defects of the diabetic foot represent a reconstructive challenge. The aim of the study is to analyse the efficiency of healing methods using splitted skin graft corroborated with negative pressure therapy for wounds resulted after diabetic foot surgery. Second of all, the study intends to highlight the role of a sequence of the multidisciplinary approach, in this case general surgeon-plastic surgeon, in assuring the functionality of the pelvic limb. Methods: 63 diabetic patients were retrospectively analysed, patients that were admitted in Dr.I.Cantacuzino and Bagdasar-Arseni Clinical Hospitals, with different types of wounds resulted after diabetic foot surgery, between January 2016 and December 2017. Results: The reconstructions were successful in 56 patients, and, during the follow-up period, there were no complications. From the 7 patients with complications (skin graft necrosis, skin graft infection), one had an auto avulsion of the skin graft. Conclusion: Direct closure is feasible for small-sized wounds. Skin grafts provide effective coverage for large wounds, although they may often produce concave, caved-in, non-aesthetic closures. NPWT (negative pressure wound therapy) is also a very helpful procedure. Flap reconstruction often provides superior functional and aesthetic appearance. Adjacent tissue transfers may be used to close many wounds, but dermal restraint may hinder motion and lead to closure tension. Alternative solution of repair remains the reconstruction with free flaps, which also poses problems, due to arteriopathy.

Current Surgical Approach in the Pathology of the Arteriopathic Predominant Diabetic Foot.

Introduction: The diabetic foot is a complex pathologic entity characterized by the totality of modifications appearing on the foot during the evolution of the diabetic disease. This survey aims to elaborate an algorithm of treatment for patients with arteriopathic predominant diabetic foot lesions, with the purpose of reducing the number of debilitating interventions and improving the quality of life. Material and Method: There were analysed a number of 188 patients admitted to the Surgery Clinic I of the Dr.I.Cantacuzino Clinical Hospital, in the year 2017, suffering from arteriopathic predominant diabetic foot lesions, based on several inclusion/exclusion criteria. Results: According to the type of foot lesion, most patients had the diagnosis of wet gangrene of the toe/toes (51.06%), followed by ischaemic gangrene of the toe/toes (40.4%); the surgical interventions performed on these types of lesions in 73.9% of the cases consisted of minor amputations (transmetatarsal amputation of the toe/toes/foot). Conclusions: The treatment algorithm developed as a result of this survey represents a feasible treatment solution for the pathology of the arteriopathic predominant diabetic foot and failure to comply with this treatment may lead to treatment errors in a sense in which disproportional surgery can be performed in correlation with an inexact diagnosis.

Surgical Complications of Peritoneal Dialysis.

Peritoneal dialysis (PD) is a method of renal function replacement which has a series of advantages like greater autonomy of the patient with fewer hospital visits and better preservation of residual renal function, but it has also disadvantages. The main disadvantages are a limited life-time due to peritoneal membrane failure and the risk of infections. The main complication of PD remains peritonitis, which is responsible for the most cases of method failure. There are also other complications which incorrect treated may lead to failure of the method: mechanical complications, abdominal wall defects, exit site and tunnel infections. Encapsulating peritoneal sclerosis is a rare entity found in PD patients but with high morbidity and mortality. We have retrospectively analyzed the patients with end stage renal disease under peritoneal dialysis which were admitted to Surgical Clinic "I. Juvara" of the Clinical Hospital "Dr. I. Cantacuzino" between 2007 and 2017 for surgical complications related to PD. The patients were assigned in two groups: with non-infectious and infectious complications. We have found 109 patients which have had 126 surgical interventions related to peritoneal dialysis. Out of these, 30 interventions consisted in catheter removal for loss of ultrafiltration capacity, so these were excluded from analysis. The lot resulted consisted in 80 patients with 91 complications: 42 non-infectious and 49 infectious. Mean age was 60.5 (+-12.3) years. Sex distribution was 2.75/1 male/female. Diabetes mellitus was present at 45 (56,25 %) patients. Comparing the patients with non-infectious with those with infectious complications we found significant association between type of complications and the length of PD in the sense that infectious complications tend to appear later than the non-infectious. Also, the loss of peritoneal dialysis is strongly associated with infectious complications. Looking inside groups we found that abdominal wall defects are associated with the history of previous abdominal surgery (p 0,001). Regarding the morbidity and mortality only infectious complications had associated mortality in our study, there were no significant differences in morbidity rate between groups. Between all these patients we have also identified 16 with encapsultating peritoneal sclerosis. In most cases the diagnosis was established during the intervention for another complication. We have registered a 20% morality rate at these patients. Conclusions: Noninfectious surgical complications are not raising problems for diagnosis or surgical treatment, but an incorrect treatment may lead to failure of the PD. Infectious complications and especially peritonitis remains the main cause of method failure. These are generating the highest rates of morbidity and mortality from peritoneal dialysis complications. Even if the immediate surgical intervention for peritonitis related to peritoneal dialysis is usually unnecessary, surgical observation is absolutely mandatory in every case. The absence of a response to the proper medical treatment is an indication for peritoneal cavity exploration inclusive by laparoscopy/laparotomy. Any delay in diagnosis and definitive treatment can lead to loss of peritoneal membrane function and even death of the patient. Encapsulated peritoneal sclerosis is a rare but serious complication of PD. The risk for developing EPS increases with the duration of PD treatment. No predictive and reliable screening tests especially in the early stages of EPS were found. So, it is important not to underestimate the clinical symptoms, diagnosis being based on a high index of suspicion. The only established basic treatment of EPS is enterolysis of peritoneal adhesions, and time should not be unnecessarily wasted on conservative treatment.

Diabetes Mellitus as a Risk-factor for Colorectal Cancer Literature Review - Current Situation and Future Perspectives.

Colorectal cancer and Diabetes Mellitus represent a major public health issue, first, by the number of new cases which are at an alarming rate. Secondly, by the negative effect over the quality of life, socio-economic status and lifespan, representing high morbidity and mortality causes. Diabetes Mellitus is the disease of the century with a global prevalence (standardised-age) which doubled since 1980, rising from 4,7% to 8,5% in adult population. In 2012, the estimated number of fatalities caused by Diabetes Mellitus and other related complications was at 3,7 million, out of which 43% were patients under the age of 70. Neoplasia represents the second cause of death, after cardiovascular disease. The occurrence of Colorectal cancer (CRCA) is rated for men and women at 3rd and 2nd place. However, the rate of mortality from CRCA is in the 4th place, representing 8,5% out of the total cancer related deaths. 52% of these cases are recorded in underdeveloped countries, considering their level, this reflects a very low survival rate. Moreover, every year, approximately 1.4 million cases are being diagnosed out of which 55% appear in overdeveloped countries. Screening for colorectal cancer refers to the periodical evaluation of the asymptomatic patients who are at a risk of developing this type of neoplasia. The colorectal cancer contains a series of particularities which makes it ideal for screening. Since the end of the 19th century there has been a high suspicion that type II diabetes, through direct etiological mechanisms, may play a part in carcinogenesis (breast, endometrium, colorectal, pancreas, liver, non-Hodgkin's lymphoma). At the moment, the relevant published literature presents type II diabetes as an independent risk factor for colorectal cancer. Although, despite experimental proof, many epidemiological studies, case-controlled studies and meta-analysis, there still is the necessity for prospective studies which can intensify the existing results and can allow the colorectal cancer screening to adapt to these patients.

Surgical Management of Diabetic Neuropathy Foot Complications.

Background: Diabetic foot complications result from the association between peripheral vascular disease, neuropathy and a precarious healing process. Peripheral neuropathy observed in diabetics affects all components of the nervous system, contributing to the occurrence of leg ulcers, musculoskeletal changes, resulting in severe deformities. The clinical manifestation of these complications ranges from simple lesions to complex entities threatening the loss of pelvic limb or even life (1,2). Methods: In our surgery department, a significant number of patients with diabetic foot lesions are hospitalized and treated annually, 40% having clinical manifestations of diabetic neuropathy associated. In 2017, a total of 448 patients were hospitalized for complications of diabetes. We performed a retrospective analysis of 150 consecutive patients who underwent surgery for neuropathic diabetic foot lesions. Results: The analyzed patients had a favorable postoperative progression, benefiting from distal perfusion. Ray resection was the preferred surgical intervention. Major amputation was performed in 10% of cases with extensive gangrene and sepsis, amputation of the calf being preferred in all situations. Conclusions: The management of these patients is delicate, often multidisciplinary approach being necessary. A well-managed therapeutic attitude can make the difference between preserving or losing the pelvic limb.

Soft Tissue Infections in Diabetic Patients.

Background: the patient with diabetes has an increased susceptibility to infections, with negative evolutionary potential leading to increased morbidity and mortality compared to the general population. The cause is the alteration of immune defense mechanisms, the hyperglycemic environment leading to alteration of neutrophil function, suppression of the antioxidant system and humoral activity, systemic micro and macroangiopathy, neuropathy, depression of antibacterial activity of the genitourinary and digestive tract. Infections localized at the soft tissue (skin, fascia and aponeurosis, subcutaneous tissue, muscles) in the diabetic patient require a complex medico-surgical approach in which aggressive surgical treatment should be complemented by metabolic balancing and sustained antibiotic therapy. Materials and methods: these peculiarities will be exposed and analyzed in a retrospective descriptive study performed at the General Surgery Clinic. Juvara of the clinical hospital Dr. I. Cantacuzino, during the period of Jan. 2013- Dec.2017, which followed the type of lesions, their localization, the germs involved, the comorbidities, the biologic parameters, the antibiotic and surgical treatment as well as the postoperative evolution. The study does not include patients with localized infections in the diabetic foot, a particular pathological entity that will be analyzed separately in a separate study. Results: 150 diabetic patients with soft tissue infections localized in the upper limb, calf, thigh, perineum, abdominal and thoracic wall were identified. The most frequent localization was found in the lower limb (54%). The incidence of these infections was higher in males (55%), and the most affected age group was 60-69 years (38%). Most patients had type II diabetes (93%). Among the associated comorbidities, cardiovascular diseases and obesity are the most common, explaining to a large extent the complicated evolution, potentially lethal of this pathology. From the bacteriological perspective, a plurimicrobian flora is identified, staphylococcus aureus being most frequently encountered. The antibiotic treatment was initiated immediately empirically, subsequently according to the antibiogram; the most commonly used antibiotic classes being cephalosporins and carbapenems. Surgical interventions were in their majority of debridement and necrectomy, but in a few cases limb amputation was necessary. In particular, the number of surgical interventions performed in the same patient and in the same hospital stay was between 1 and 7 interventions. Conclusions: Soft tissue infections in the diabetic patient have a heterogeneous aspect with specific particularities requiring careful clinical examination, multidisciplinary treatment including rapid, serial surgical interventions to control the growing aggression of the germs involved. Fast and caseadapted therapeutic decisions, careful observation of the patient's general condition and of the wound several times a day are essential to achieving favorable postoperative outcomes.

Synchronous Locally Advanced Rectal Cancer with Clinical Complete Remission and Important Downstaging after Neoadjuvant Radiochemotherapy - Personalised Therapeutic Approach.

Introduction: The current practice for patients with good response, important downstaging or complete remission after preoperative chemoradiation, is to perform surgery on the basis of initial pretherapeutical staging. In literature, varying approaches, like transanal endoscopic microsurgery and even "wait and see", are described for patients with good response after chemoradiation. However, considering the present level of available evidence, the wide-spread adoption of a "watch and wait" policy in those achieving a complete clinical remission cannot be justified. CASE REPORT: It is presented the case of a 63 years old patient, investigated and diagnosed with synchronous rectal cancer, inferior rectal cancer invading the perianal region and medium rectal cancer, located between 8 and 14 cm from the anal verge, pretheraputically staged cT4N2M0. The oncological board decides neoadjuvant radiochemotherapy. Restaging shows complete remission of inferior rectal tumor and ulcerative infiltrative remnant lesion in the medium rectum. The patient firmly declines colostomy, assuming recurrence risks. A TME low rectal resection with colorectal mechanical anastomosis is performed, postoperative evolution being favorable. Conclusions: Although, the radical surgery to be done would have been an abdomino-perineal resection, the patient's option to decline the colostomy imposed a radical intervention just for the proximal tumor. The inferior rectal tumor, with complete remission after neoadjuvant therapy was submitted to "wait and see" approach.
