Minimally invasive vessel-preservation spleen preserving distal pancreatectomy-how I do it, tips and tricks and clinical results.

BACKGROUND: Minimally invasive spleen-preserving distal pancreatectomy (SPDP) has emerged as a parenchyma-preserving approach and has become the standard treatment for pancreatic benign and low-grade malignant lesions. Nevertheless, minimally invasive SPDP is still technically challenging, especially when vessel preservation is intended. This study aims to describe the technique and outcomes of laparoscopic (LSPDP) and robot-assisted spleen-preserving distal pancreatectomy (RSPDP) with intended vessel preservation, highlighting the important tips and tricks to overcome technical obstacles and optimize surgical outcomes. METHODS: A retrospective observational study of consecutive patients undergoing LSPDP and RSPDP with intended vessel preservation by a single surgeon in two different centers. A video demonstrating both surgical techniques is attached. RESULTS: A total of 50 patients who underwent minimally invasive SPDP were included of which 88% underwent LSPDP and 12% RSPDP. Splenic vessels were preserved in 37 patients (74%) while a salvage vessel-resecting technique was performed in 13 patients (26%). The average surgery time was 178 ± 74 min for the vessel-preserving and 188 ± 57 for the vessel-resecting technique (p = 0.706) with an estimated blood loss of 100 mL in both groups (p = 0.663). The overall complication rate was 46% (n = 23) with major complications (Clavien Dindo ≥ III) observed in 14% (n = 7) of the patients. No conversions occurred. The median length of hospital stay was 4 days. CONCLUSION: This study presented the results after minimally invasive SPDP with intended vessel preservation by a highly experienced pancreatic surgeon. It provided tips and tricks to successfully accomplish a minimally invasive SPDP, which can contribute to quick patient rehabilitation and optimal postoperative results.

Oromandibular Limb Hypogenesis Syndrome: Overlap of Moebius and Ankyloglossia Superior With Severe Limb Defects.

The oromandibular limb hypogenesis syndromes (OLHS) represent a group of rare conditions characterized by congenital malformations involving the tongue, mandible, and limbs. In this report, we describe a newborn girl with paralysis of abducens and facial nerves, transverse agenesis of the distal segments of the limbs, micrognathia, cleft lip and palate, and ankyloglossia superior. This observation confirms an overlap between Moebius syndrome and ankyloglossia superior syndrome with severe limb defects. The etiology of the OLHS is not clearly understood. The intriguing link between facial and limb anomalies can result from their simultaneous development from the fourth to eighth week of gestation, making both areas susceptible to the same teratogenic stimuli. There is an overlap between OLHS conditions, supporting a clustering, rather than a divided nosology and requiring an appropriate classification of these conditions. Patients with OLHS can be successfully managed using a multidisciplinary approach.

The Best Protocol to Treat Equine Skin Wounds by Second Intention Healing: A Scoping Review of the Literature.

Equine skin wound treatment continues to be a challenge for veterinarians. Despite being a frequent practice, it remains difficult to choose an evidence-based treatment protocol. This study aimed to comprehensively explore the literature and provide a scoping review of therapeutic strategies for equine skin wounds and identify knowledge gaps and opportunities for future research. This review was conducted using specific criteria to select literature that described methods to manage second intention wound healing. After removing duplicates and screening papers for suitability, 81 manuscripts were included for data extraction. Of these, 59 articles were experimental studies, 10 were case reports, 9 were case series, and 3 were clinical studies. The most frequent wound location was the distal limbs. Macroscopic assessment was the main tool used to evaluate treatment effectiveness. All of the case reports, case series, and clinical studies reported positive outcomes with regard to the treatment used, while only 36% of the experimental studies found significant healing improvement in treated wounds compared to control groups. It was found that there are many treatments that have exhibited controversial results, and there exists a lack of evidence for the adoption of specific treatment protocols.

Adjuvant Botulinum Toxin Type A on the Management of Giant Hiatal Hernia: A Case Report.

The management of giant hiatal hernias (HHs) remains challenging and is associated with a high risk of recurrence. Currently, several strategies are used to reduce recurrence, and a newly proposed trend is the administration of adjuvant botulinum toxin type A (BTX), a procedure already performed in complex ventral hernias. Here, we present a case of a 63-year-old man with a giant paraesophageal HH type IV containing the entire stomach and transverse colon with loss of domain, who underwent adjuvant BTX and subsequently laparoscopic hiatoplasty with a biological mesh with partial fundoplication. At six months' follow-up, the patient reported a significant improvement in the quality of life without dysphagia or gastroesophageal reflux and with a good respiratory function. A control computed tomography was performed, which documented a partial recurrence of HH, completely asymptomatic. This clinical case showed the successful treatment of a giant HH using adjuvant BTX injection to increase abdominal wall compliance as had already been described in the treatment of complex ventral hernia. Thus, the use of BTX is a promising strategy for selected cases of giant HHs mainly if there is a loss of domain; however, more case series and controlled trials are needed to show the reproducibility of the benefit of this strategy.

Thromboembolic Complications After Bariatric Surgery: Is the High Risk Real?

INTRODUCTION: Nowadays, a large number of bariatric surgery (BS) procedures are undertaken worldwide as surgery has become an efficient strategy to treat the obesity epidemic. The risk of venous thromboembolism (VTE) is increased in patients undergoing BS not only due to the intrinsic surgical risk but also because patients with obesity have a 2-3-fold higher risk of VTE. The optimal strategy for VTE prevention in BS setting, including optimal dose and thromboprophylaxis regimen, is still not fully clarified. The aim of this study was to report a bariatric high-volume center experience and to propose a practical thromboprophylaxis protocol for this population. METHODS: A single-center, observational, retrospective, and longitudinal study was conducted from January 2018 to December 2020, a total of 901 patients who underwent primary and revisional bariatric surgery were included. RESULTS: The overall frequency of VTE events was 0.44% (n=4), one patient had pulmonary embolism (PE) during index hospital admission; another patient had simultaneous deep venous thrombosis (DVT) and PE, two months after surgery; and two other patients had DVT, nine and 16 months after surgery. The median time for VTE was four months. The incidence of females was 75% (n=3) and the median age was 57 years. Only one female patient was using oral contraception. None had a previous history of thromboembolic events, chronic venous insufficiency, or other known diseases that could increase the VTE risk. CONCLUSION: Considering the outcomes reported by this experienced center with low rates of thromboembolic events, we suggest a thromboprophylaxis protocol that can be easily applied to the majority of bariatric patients.

Acute Pericarditis Hiding an Esophageal Perforation.

Esophageal perforations due to foreign body ingestion are uncommon; however, they can be associated with extremely high mortality rate. The most dreadful complication of this entity is the infection of adjacent structures, namely, the mediastinum and the pericardium. A prompt diagnosis and a precocious start of treatment are essential to the prognosis. Thus, a high degree of suspicion is required, especially in older patients. Therapeutic options are highly variable, depend on several factors, and should be individualized to every patient and their clinical status. Surgical treatment with esophageal exclusion and diversion, in extreme circumstances, is mandatory to control the infection source site and prevent further contamination. We report a case of esophageal perforation, presenting 48 hours after onset, that led to multifactorial shock (septic and cardiogenic) due to pericarditis with pericardial and pleural effusion.

Laryngeal perforation during Sistrunk procedure.

Thyroglossal duct cyst (TGDC) is the most common congenital neck anomaly in childhood, although it can be diagnosed at any age group. Ultrasound of the thyroid gland and the neck structures is an appropriate tool for diagnosis. The authors aim to report a rare case of a 22-year-old male with a laryngeal perforation during a TGDC excision and raise awareness to this potentially life-threatening complication. The Sistrunk procedure is the surgical treatment of choice with a low morbidity and recurrence rates.

Adenomyomatous Hyperplasia of Ampulla of Vater and a Concomitant Renal Tumor: A Case Report.

Adenomyomatous hyperplasia is an extremely rare lesion encountered in the ampulla of Vater. Less than 50 cases have been described, most of them with clinical consequences of biliary obstruction, misdiagnosing it as a malignancy. The authors present a concomitant case with a renal tumor, its diagnosis, management, and clinical relevance, as well as a brief revision of the literature. Ampullar and renal tumors were found in a 74-year-old female, in the imagiologic study of a low back pain, in the emergency department. Both were considered malign after further study, and pancreatoduodenectomy with partial nephrectomy was proposed. There is no accurate diagnostic tool to differentiate the benign nature of adenomyomatous hyperplasia and extensive operations are often performed. As an incidental finding in the study of another tumor, this case raises the concern about which and how to treat both tumors, taking into account the morbidity of the respective interventions.

Pasteurized milk: efficiency of pasteurization and its microbiological conditions in Brazil.

This study aimed to verify the pasteurization efficiency and the microbiological quality of milk sold in the city of Rio de Janeiro, Brazil. The microbial quality of pasteurized milk samples was assessed by sample testing for the presence of Salmonella spp., coliforms at 35 degrees C, coliforms at 45 degrees C, and mesophilic bacterial counts. In addition, the pasteurization efficiency was verified through tests of neutral phosphatase and peroxidase enzymes. Salmonella spp. were not detected in any (100%) of the analyzed samples. However, 85 (70.8%) and 69 (57.5%) of the samples were noncompliant with current legal standards for coliforms at 35 degrees C and 45 degrees C, respectively. As for the aerobic mesophilic bacteria, 48 (40.0%) of the samples were noncompliant. From the 120 samples of pasteurized milk studied, 100% were negative for neutral phosphatase, whereas 12 (10.0%) were negative for peroxidase. Logistic regression indicated the absence of relationship between present lactoperoxidase and all the microbiological parameters studied, which suggested that the quality of pasteurized milk was associated with factors related to steps before or after heat treatment.

Lung Nodule and Food Bolus Impaction: Can They Be Related?

Achalasia is a rare primary disorder of esophageal motility characterized by insufficient lower esophageal sphincter relaxation and loss of esophageal peristalsis. This results in patient complaints of dysphagia to solids and liquids, regurgitation, chest pain, and weight loss. However, achalasia may also present with respiratory symptoms, such as aspiration pneumonia, due to remarkable regurgitation. In untreated patients and a long period of evolution, respiratory symptoms may even be the initial manifestation of achalasia. An endoscopic finding of retained food and saliva with a puckered gastroesophageal junction or barium swallow showing dilated esophagus with birds beaking in a symptomatic patient should prompt appropriate diagnostic and therapeutic strategies. We describe an atypical presentation of a rare disease in a young man with a history of symptoms caused by the late manifestation of achalasia.

End-of-Life Nursing Knowledge Among Nursing Students.

BACKGROUND: The U.S. health care system is poorly designed to meet the needs of patients at the end of life (EOL) and their families. Nursing students often have reported feeling inadequate to provide EOL care. METHOD: Following an EOL simulation, reflective journals were collected from junior and senior nursing students and analyzed for themes using qualitative content analysis. The condensed meaning units were abstracted into codes based on Carper's fundamental patterns of knowing. RESULTS: Thirty-one junior and senior nursing students (mean age, 21.04 ± 0.52 years, 96.2% female) in a baccalaureate program participated in the study. The broad themes of student reflections included empirics (theoretical or natural historical) aesthetics (transformative nursing action), personal (interpersonal process of nurse-patient interaction), and ethics (emotion influences actions). CONCLUSION: Student perception and participation in all roles contributes to the gestalt of the experience of a highly emotional EOL simulation for both students and faculty.

Large mucinous cystic neoplasm of the pancreas during pregnancy: a case report.

Mucinous cystic neoplasms (MCNs) of the pancreas occurring during pregnancy constitute a rare condition requiring special management due to its large size, malignant potential and the risk of fetal growth restriction. The key points to manage MCNs are to perform a correct diagnosis, accurately evaluate the grade of malignant potential in order to establish the right time for pancreatic surgery and to choose the most appropriate fetal mode of delivery. We describe a case of an incidental abdominal mass detected in a third-trimester pregnant woman. At surgery, a huge pancreatic cystic tumour was found and a distal pancreatectomy with splenic preservation was performed. The histopathological analysis revealed an MCN of the pancreas with low-grade dysplasia. To our knowledge, this is the largest pancreatic MCN detected in a pregnant woman reported in the literature and one of the few successfully resected after vaginal delivery.

Molecular signatures define two main classes of meningiomas.

BACKGROUND: Meningiomas are common brain tumors that are classified into three World Health Organization grades (benign, atypical and malignant) and are molecularly ill-defined tumors. The purpose of this study was identify molecular signatures unique to the different grades of meningiomas and to unravel underlying molecular mechanisms driving meningioma tumorigenesis. RESULTS: We have used a combination of gene expression microarrays and array comparative genomic hybridization (aCGH) to show that meningiomas of all three grades fall into two main molecular groups designated 'low-proliferative' and 'high-proliferative' meningiomas. While all benign meningiomas fall into the low-proliferative group and all malignant meningiomas fall into the high-proliferative group, atypical meningiomas distribute into either one of these groups. High-proliferative atypical meningiomas had an elevated median MIB-1 labeling index and a greater frequency of copy number aberrations (CNAs) compared to low-proliferative atypical meningiomas. Additionally, losses on chromosome 6q, 9p, 13 and 14 were found exclusively in the high-proliferative meningiomas. We have identified genes that distinguish benign low-proliferative meningiomas from malignant high-proliferative meningiomas and have found that gain of cell-proliferation markers and loss of components of the transforming growth factor-beta signaling pathway were the major molecular mechanisms that distinguish these two groups. CONCLUSION: Collectively, our data suggests that atypical meningiomas are not a molecularly distinct group but are similar to either benign or malignant meningiomas. It is anticipated that identified molecular and CNA markers will potentially be more accurate prognostic markers of meningiomas.

Comparative analysis of the prevalence of the glutathione S-transferase (GST) system in malignant and benign thyroid tumor cells.

CONTEXT AND OBJECTIVE: When null, the mu and theta genes of the glutathione S-transferase system (GSTM1 and GSTT1, respectively) are related to malignant tumors affecting the lungs, colon, prostate, bladder and head and neck. In the thyroid, the appearance of cancer has been correlated with deletion of these genes. The aim of this study was to compare the frequencies of these genes in patients with benign and malignant tumors of the thyroid gland. DESIGN AND SETTINGS: This was a cross-sectional clinical trial carried out in the Head and Neck Surgery Division, Faculdade de Medicina da Santa Casa de São Paulo. METHODS: Samples of thyroid tissue were collected from 32 patients and divided into two groups: benign tumor (A) and malignant tumor (B). After DNA extraction, the genes were amplified using PCR. RESULTS: The B group presented four cases of positive genotyping for both genes, seven positive for GSTT1 and negative for GSTM1, two negative for GSTT1 and positive for GSTM1, and only one case of double negative. The A group showed 11 cases with positive genotyping for both genes and none with the double negative genotype. CONCLUSION: In this study, there was no relationship between the presence of the GSTT1 and GSTM1 genes and the benign and malignant thyroid tumors.

Effect of different home-cooking methods on the bioaccessibility of zinc and iron in conventionally bred cowpea (Vigna unguiculata L. Walp) consumed in Brazil.

BACKGROUND: The cowpea (Vigna unguiculata L. Wap.) is an excellent source of iron and zinc. However, iron from plant sources is poorly absorbed compared with iron from animal sources. OBJECTIVES: The objective of this study was to evaluate iron and zinc bioaccessibility in cowpea cultivars after processing. METHODS: Zinc and iron bioaccessibilities in cowpea samples were determined based on an in vitro method involving simulated gastrointestinal digestion with suitable modifications. RESULTS: When water-soaked beans were cooked in a regular pan, the highest percentage of bioaccessible iron obtained was 8.92%, whereas when they were cooked in a pressure cooker without previous soaking, the highest percentage was 44.33%. Also, the percentage of bioaccessible zinc was 52.78% when they were cooked in a regular pan without prior soaking. Higher percentages of bioaccessible iron were found when cooking was done in a pressure cooker compared with regular pan cooking. In all cultivars, cooking of cowpea beans in both pressure cooker and in a regular pan yielded higher percentages of bioaccessible zinc compared with availability of bioaccessible iron. CONCLUSIONS: Iron bioaccessibility values suggest that cooking in a regular pan did not have a good effect on iron availability, since the percentage of bioaccessible iron was lower than that of zinc. The determination of iron and zinc bioaccessibility makes it possible to find out the actual percentage of absorption of such minerals and allows the development of efficient strategies for low-income groups to access foods with high levels of these micronutrients.

Oral health impacts on daily living related to four different treatment protocols for chronic periodontitis.

BACKGROUND: The aims of this study were to evaluate the oral health impacts perceived by patients submitted to different treatments of chronic periodontitis and their association with clinical parameters. METHODS: Sixty patients were assigned to one of the following therapeutic groups: control, treated with full-mouth scaling and root planing (SRP); test 1, treated with SRP and 400 mg systemically administered metronidazole (MET) three times per day for 10 days; test 2, treated with SRP and professional supragingival plaque removal (PP) every week for 3 months; and test 3, treated with SRP and MET plus PP. Clinical periodontal measurements and data regarding patients' oral health impacts (perceived impacts on bleeding gums, gingival recession, sensitivity to cold, packing foods, aesthetics, bad breath, and tooth mobility) were collected at baseline and 3 months after therapy. RESULTS: All groups presented significant improvement in oral health perceived impacts. There was no statistically significant difference in the improvement of oral health impacts among groups subjected to different treatments. The clinical data of percentage of deep probing depth, deep clinical attachment level, and bleeding on probing were found to be correlated significantly with oral health impacts. CONCLUSIONS: Periodontal treatment leads to a significant reduction of self-perceived impacts regardless of the non-surgical treatment protocol employed. Most of the clinical data were associated with oral health impacts.

Proposta de reuso da água utilizada no pré-preparo de hortifrutigranjeiros e na higienização de pratos e talheres em um restaurante universitário no Estado do Rio de Janeiro / Prpoposal for reuse of water for the pre-preparation of fruit and vegetables and the sanitization of dishes and flatware in a university restaurant in the state of Rio de Janeiro

Objetivo: O presente estudo teve como objetivo elaborar uma proposta para o reuso de água em um restaurante universitário no Estado do Rio de Janeiro, além de propor medidas para redução do seu consumo. Metodologia: Foi aplicado um formulário para quantificação do consumo de água nas etapas de pré-preparo de hortifrutigranjeiros e na higienização de pratos e talheres, em um período de 9 e 13 dias, respectivamente. Em seguida, foi estimado o volume, em litros, de água potável utilizado diariamente em cada etapa. Resultados: Na etapa de pré-preparo de hortifrutigranjeiros, calculouse que são utilizados 2.400 litros por dia; e na etapa de higienização de pratos e talheres, estimou-se o uso de 478 litros por dia. Desta forma, pôde-se calcular o volume total de 2.878 litros por dia que ficarão armazenados para o reuso com fins não potáveis, como por exemplo, a higienização do piso dos refeitórios do restaurante, o que representa 31,97% da quantidade necessária para limpeza de todo o restaurante universitário. Além disso, realizou-se a quantificação dos pontos de água para possível instalação de arejadores nas torneiras, no intuito de reduzir o consumo. Em seguida, elaborou-se o projeto do reservatório de água para reuso. Conclusão: Por fim, atestou-se a importância da proposta apresentada, tendo em vista a significativa quantidade de água com possibilidade de reuso que é desperdiçada diariamente, contribuindo-se assim com a preservação ambiental e diminuição dos custos do restaurante universitário. (AU)

Objective: The aim of the present study was to propose the reuse of water in a university restaurant in the state of Rio de Janeiro, as well as measures to reduce consumption. Methods: A form was applied to quantify water consumption during the pre-preparation of fresh produce and the sanitization of dishes and flatware, within a period of 9 and 13 days, respectively. Later, the volume of potable water used daily was estimated in liters. Results: The estimated volume of water used per day was 2.400 liters for pre-preparation of fresh produce and 478 liters of water per day for sanitization of dishes and flatware. Thus, a total volume of 2.878 liters of water per day for non-potable reuse was estimated, such as, for example, for the sanitization of the dining hall floor of the restaurant. In addition, the quantification of water points for possible installation of faucet aerators was made aiming to reduce consumption. Next, a project of the storage container for the reuse of water was developed. Conclusion: It may be concluded that the importance of the proposal is related to the significant quantity of daily wasted water that could be reused and thus, contribute to environmental preservation and decrease the water expenses of the university restaurant.

Consumption of açai (Euterpe oleracea Mart.) functional beverage reduces muscle stress and improves effort tolerance in elite athletes: a randomized controlled intervention study.

The study analyzed the effect of an açai (Euterpe oleracea Mart.) functional beverage (AB) on muscle and oxidative stress markers, cardiorespiratory responses, perceived exertion, and time-to-exhaustion during maximal treadmill running. The beverage was developed as an ergogenic aid for athletes and contained 27.6 mg of anthocyanins per dose. Fourteen athletes performed 3 exercise tests: a ramp-incremental maximal exercise test and 2 maximal exercise bouts performed in 2 conditions (AB and without AB (control)) at 90% maximal oxygen uptake. Blood was collected at baseline and after maximal exercise in both conditions to determine biomarkers. AB increased time to exhaustion during short-term high-intensity exercise (mean difference: 69 s, 95% confidence interval = -296 s to 159 s, t = 2.2, p = 0.045), attenuating the metabolic stress induced by exercise (p < 0.05). AB also reduced perceived exertion and enhanced cardiorespiratory responses (p < 0.05). The AB may be a useful and practical ergogenic aid to enhance performance during high-intensity training.
