Prevention and management of pancreatic fistula after pancreatoduodenectomy with precise and comprehensive opinion / 中华消化外科杂志

Pancreaticoduodenectomy (PD) is a major operation of abdominal surgery, with high risk, complex operation, more complications and high mortality. Pancreatic fistula is the main cause of death after PD. Due to its complexity and obstinacy, pancreatic fistula has become the top challenge of pancreatic surgery. The authors review the relevant literature and summarize the prevention and management of pancreatic fistula after PD, such as the optimization strategies for pancreatic anastomosis, the use of external stents, prophylactic drains in surgical field, the applica-tion of somatostatin and its analogues, and whole-course nutrition management, based on the precise and comprehensive opinion, in order to provide reference for improving the prevention and treatment of pancreatic fistula after PD.

An overview of COVID-19 / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Pneumonia caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection emerged in Wuhan City, Hubei Province, China in December 2019. By Feb. 11, 2020, the World Health Organization (WHO) officially named the disease resulting from infection with SARS-CoV-2 as coronavirus disease 2019 (COVID-19). COVID-19 represents a spectrum of clinical manifestations that typically include fever, dry cough, and fatigue, often with pulmonary involvement. SARS-CoV-2 is highly contagious and most individuals within the population at large are susceptible to infection. Wild animal hosts and infected patients are currently the main sources of disease which is transmitted via respiratory droplets and direct contact. Since the outbreak, the Chinese government and scientific community have acted rapidly to identify the causative agent and promptly shared the viral gene sequence, and have carried out measures to contain the epidemic. Meanwhile, recent research has revealed critical aspects of SARS-CoV-2 biology and disease pathogenesis; other studies have focused on epidemiology, clinical features, diagnosis, management, as well as drug and vaccine development. This review aims to summarize the latest research findings and to provide expert consensus. We will also share ongoing efforts and experience in China, which may provide insight on how to contain the epidemic and improve our understanding of this emerging infectious disease, together with updated guidance for prevention, control, and critical management of this pandemic.

Research advances in the prevention and treatment of radiation-induced dermatitis / 中华放射肿瘤学杂志

Radiation-induced dermatitis (RD) is one of the most common complications induced by radiotherapy in cancer patients.The incidence and severity of RD are largely associated with the risk factors of patients.RD can severely affect the quality of life,even discontinue the treatment and reduce the tumor control rate in severe patients.Currently,randomized control trials evaluating the preventive measures for acute RD have been rarely conducted.The clinical interventions for acute RD significantly vary.In this article,the pathogenesis,risk factors,clinical manifestations,evaluation,prevention and treatment of RD were investigated.

Diagnosis and management of urinary tract stone in family practice

Background@#Urinary tract stones or calculi are low-density crystals in any part of the urinary tract that result from either excessive excretion or precipitation of salts in the urine or lack of substances to inhibit its formation. Prevention and management of urinary tract stones is also now medically feasible and recommended.@*Objectives@#This clinical pathway was developed to guide family and community physicians on the diagnosis and initial management of urinary tract stone in terms of: 1) clinical history and physical examination; 2) laboratory and ancillary procedures to be requested; 3) pharmacologic interventions; 4) non-pharmacologic interventions; and 5) patient outcomes to expect.@*Methods@#The PAFP Clinical Pathways Group reviewed the previous guidelines for the treatment of urinary tract stones, published medical literature (PubMed and HERDIN) to identify, summarize, and operationalize the clinical content of diagnostics, interventions and clinical indicators or outcomes to develop an evidence-based clinical pathway in family medicine practice.@*Recommendations@#Family physicians should elicit patient history of flank pain, tenderness, dysuria and hematuria. They must be described in detail in terms of, characteristics, date of onset and severity. Other patient history to elicit should include stone passage, recurrent UTI, dietary history, fluid intake, recurrent UTI, medications and family history of being a stone former or some metabolic disorder. The laboratory should include ultrasound of kidney, ureter and bladder (plain CT is second line imaging study), urinalysis and blood chemistry (BUN, creatinine, calcium and uric acid). Symptomatic treatment with non-steroidal anti-inflammatory drugs or opioid analgesic in severe pain should be started even before the definitive diagnosis. Anti-spasmodic therapy may also be given. If stone is present, medical dissolution therapy for all stone sizes (alone or as complementary to medical expulsion, lithotripsy or surgery), medical expulsion therapy for stone size 5-10 mm and lithotripsy or surgery if greater than 10 mm. Non-pharmacologic treatment includes patient education, increased fluid intake to achieve at least 2-2.5 liters of urine per day and limit sodium intake (no evidence to limit calcium or protein intake). Family intervention to adjust family diet preference to low sodium is also recommended. @*Implementation@#To promote rational management of urinary tract stone in family practice, outreach visits to individual family physician’s clinic have been identified as an intervention that may improve the practice of health care professionals. This type of ‘face to face’ visit has been referred to educational detailing or academic detailing. Organizational activities such as quality improvement activities will also be encouraged.

Patient safety management in the medication use process: prevention and management of medication error

Medication errors, resulting in risks to patient safety, occur throughout the entire medication use process, and include prescribing errors, dispensing errors, administering errors, and patient compliance errors. The results of many reports and studies on medication errors in several countries including the United States show that medication errors occur commonly, are costly and are often preventable. Medication errors involve a breakdown in more than one aspect of the medication use system such as lack of knowledge, standard performance and mental lapses, and defects or failure in the organizational system. Such medication errors compromise patient confidence in the healthcare system and increase healthcare costs. Hospitals must take a medication error prevention approach and also prepare various methods of managing medication errors once they have occurred. The necessity of a medication error reporting system should be emphasized. In Korea, with regard to medication errors, we have a long way to go. We have no documented data available on error rates, no published studies, and no error reporting system. In conclusion, medication errors are no longer a guarded, guilty-ridden professional secret in Korea. They should be considered problems in public healthcare policy. Therefore, we need to establish a medication error prevention and management system at the national level including a national error reporting system in the near future.

Prevention and management of chylous fistula after neck dissection / 肿瘤研究与临床

Objective To explore the occurrence and prevention and the principle of management of chylous fistula after neck dissection. Methods Retrospective research on 1750 cases of neck dissection in Henan Tumor Hospital from January 1983 to January 2005. There were 48 cases chylous fistula and 1 case chylothorax. The incidence was 2.8 %. 5 cases on the right, 44 cases on the left. 18 cases had completed radiotherapy or chemotherapy before operation. Conservative methods and surgical methods were used in the treatment. Low fat food was supplied to the patients with chylous fistula. The conservative methods was local pressure, the surgical methods was applied while maximal production of chylous exceeding 500 ml a day. Results All the patients were cured finally. The conservative method was 12.6(5~34) days, the surgical method 7.5(3~10)day. Conclusion The key to prevent chylous fistula was to band the rupture of thoracis or lymphatic duct during operation. The conservative methods could be used in patients with slight and middle chylous, when the chylous exceed 500 ml a day or the conservative methods was unavailable, the surgical methods was appropriate, it could shorten the time of tube draw.
