Unilateral acute cataract after facial aesthetic procedure: a case report

ABSTRACT Aging and face sagging have many causes, and various techniques are used for treatment, including noninvasive procedures, such as focused ultrasound, which uses the principle of collagen regeneration by coagulative necrosis of the dermis layers using radiofrequency, but this procedure has complications. We reported a case of a 54-year-old female patient who complained of poor visual acuity in her right eye three days after a focused ultrasound facial aesthetic procedure, with the best visual acuity of 20/60. Biomicroscopy of the right eye revealed an acute cataract with three points of fibrosis extending from the posterior to the anterior capsule. The patient underwent phacoemulsification surgery with visual rehabilitation and improved vision of 20/20. We hypothesized that the occurrence of acute cataract was related to the inappropriate use of focused ultrasound.

Acute kidney injury: the experience of a tertiary center of Pediatric Nephrology / Insuficiência renal aguda: experiência de um centro terciário de Nefrologia Pediátrica

ABSTRACT Introduction: Acute kidney injury (AKI) is an abrupt deterioration of kidney function. The incidence of pediatric AKI is increasing worldwide, both in critically and non-critically ill settings. We aimed to characterize the presentation, etiology, evolution, and outcome of AKI in pediatric patients admitted to a tertiary care center. Methods: We performed a retrospective observational single-center study of patients aged 29 days to 17 years and 365 days admitted to our Pediatric Nephrology Unit from January 2012 to December 2021, with the diagnosis of AKI. AKI severity was categorized according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. The outcomes considered were death or sequelae (proteinuria, hypertension, or changes in renal function at 3 to 6 months follow-up assessments). Results: Forty-six patients with a median age of 13.0 (3.5-15.5) years were included. About half of the patients (n = 24, 52.2%) had an identifiable risk factor for the development of AKI. Thirteen patients (28.3%) were anuric, and all of those were categorized as AKI KDIGO stage 3 (p < 0.001). Almost one quarter (n = 10, 21.7%) of patients required renal replacement therapy. Approximately 60% of patients (n = 26) had at least one sequelae, with proteinuria being the most common (n = 15, 38.5%; median (P25-75) urinary protein-to-creatinine ratio 0.30 (0.27-0.44) mg/mg), followed by reduced glomerular filtration rate (GFR) (n = 11, 27.5%; median (P25-75) GFR 75 (62-83) mL/min/1.73 m2). Conclusions: Pediatric AKI is associated with substantial morbidity, with potential for proteinuria development and renal function impairment and a relevant impact on long-term prognosis.

RESUMO Introdução: Insuficiência renal aguda (IRA) é uma deterioração abrupta da função renal. A incidência de IRA pediátrica está aumentando em todo o mundo, em ambientes críticos e não críticos. Nosso objetivo foi caracterizar apresentação, etiologia, evolução e desfechos da IRA em pacientes pediátricos internados em um centro de atendimento terciário. Métodos: Realizamos estudo retrospectivo observacional de centro único de pacientes com idade entre 29 dias a 17 anos e 365 dias internados em nossa Unidade de Nefrologia Pediátrica, de janeiro de 2012 a dezembro de 2021, com diagnóstico de IRA. A gravidade da IRA foi categorizada de acordo com os critérios do Kidney Disease Improving Global Outcomes (KDIGO). Os desfechos considerados foram óbito ou sequelas (proteinúria, hipertensão ou alterações na função renal em avaliações de acompanhamento de 3 a 6 meses). Resultados: Incluímos 46 pacientes com idade mediana de 13,0 (3,5-15,5) anos. Cerca de metade (n = 24; 52,2%) apresentou um fator de risco identificável para o desenvolvimento de IRA. Treze pacientes (28,3%) eram anúricos; todos foram classificados como IRA KDIGO 3 (p < 0,001). Quase um quarto (n = 10; 21,7%) dos pacientes necessitaram de terapia renal substitutiva. Aproximadamente 60% (n = 26) apresentou pelo menos uma sequela, sendo proteinúria a mais comum (n = 15; 38,5%; mediana (P25-75) da relação proteína/creatinina urinária 0,30 (0,27-0,44) mg/mg), seguida de taxa de filtração glomerular (TFG) reduzida (n = 11; 27,5%; mediana (P25-75) da TFG 75 (62-83) mL/min/1,73 m2). Conclusões: A IRA pediátrica está associada à morbidade substancial, com potencial para desenvolvimento de proteinúria e comprometimento da função renal e impacto relevante no prognóstico de longo prazo.

Occupational risks associated with chronic kidney disease of non-traditional origin (CKDnt) in Brazil: it is time to dig deeper into a neglected problem / Riscos ocupacionais associados à doença renal crônica de origem não tradicional (DRCnt) no Brasil: é hora de nos aprofundarmos em um problema negligenciado

Abstract In the past decades, an epidemic of chronic kidney disease (CKD) has been associated with environmental and occupational factors (heat stress from high workloads in hot temperatures and exposure to chemicals, such as pesticides and metals), which has been termed CKD of non-traditional origin (CKDnt). This descriptive review aims to present recent evidence about heat stress, pesticides, and metals as possible causes of CKDnt and provide an overview of the related Brazilian regulation, enforcement, and health surveillance strategies. Brazilian workers are commonly exposed to extreme heat conditions and other CKDnt risk factors, including increasing exposure to pesticides and metals. Furthermore, there is a lack of adequate regulation (and enforcement), public policies, and strategies to protect the kidney health of workers, considering the main risk factors. CKDnt is likely to be a significant cause of CKD in Brazil, since CKD's etiology is unknown in many patients and several conditions for its development are present in the country. Further epidemiological studies may be conducted to explore causal associations and estimate the impact of heat, pesticides, and metals on CKDnt in Brazil. Moreover, public policies should prioritize reducing workers´ exposure and promoting their health and safety.

Resumo Nas últimas décadas, uma epidemia de doença renal crônica (DRC) tem sido associada a fatores ambientais e ocupacionais (estresse térmico decorrente de cargas de trabalho elevadas em altas temperaturas e exposição a produtos químicos, como agrotóxicos e metais), denominada DRC de origem não tradicional (DRCnt). Esta revisão descritiva tem como objetivo apresentar evidências recentes sobre estresse térmico, agrotóxicos e metais como possíveis causas de DRCnt e fornecer uma visão geral das estratégias brasileiras de regulamentação, fiscalização e vigilância sanitária relacionadas. Os trabalhadores brasileiros são comumente expostos a condições extremas de calor e outros fatores de risco de DRCnt, incluindo o aumento da exposição a agrotóxicos e metais. Além disso, há uma falta de regulamentação e fiscalização, políticas públicas e estratégias adequadas para proteger a saúde renal dos trabalhadores em relação aos principais fatores de risco. É provável que a DRCnt seja uma causa significativa de DRC no Brasil, uma vez que a etiologia da doença é desconhecida em muitos pacientes e diversas condições para seu desenvolvimento estão presentes no país. Estudos epidemiológicos devem ser realizados para explorar associações causais e estimar o impacto do calor, dos agrotóxicos e dos metais na DRCnt no Brasil. Além disso, as políticas públicas devem priorizar a redução da exposição dos trabalhadores e a promoção de sua saúde e segurança.

Analysis of the diagnosis and treatment experience and etiological characteristics of 119 cases of primary canaliculitis / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the clinical features, diagnosis and treatment experience and the distribution characteristics of pathogenic microorganisms of primary canaliculitis, and provide reference for its diagnosis and treatment. METHODS: Retrospective clinical study. A total of 119 cases(120 eyes)diagnosed as primary canaliculitis in the department of ophthalmology of Wuxi No.2 People's Hospital from June 2019 to February 2023 were included. The treatment methods were mainly divided into conservative treatment(removing canaliculus stones through lacrimal punctum combined with injecting antibiotic eye ointment into the tube)and surgical treatment. The inspection methods of pathogenic microorganisms included secretion smear microscopy and microbial culture.RESULTS: Primary canaliculitis was more common in middle-aged and older female, mainly manifested by long-term red eye and increased secretion; however, the majority was not accompanied by tearing. Totally, 118 cases(99.2%)had monocular disease, while 63 cases(63 eyes; 52.5%)had inferior lacrimal canaliculus disease. Laboratory examination: Among 119 cases(120 eyes), 4 cases(4 eyes)did not undergo laboratory examination, and the other 115 cases(116 eyes)were as follows: Gram staining microscopy of secretion smear showed that Actinomyces were detected in 102 cases(103 eyes; 88.8%), while no fungus was detected; Microbial culture: 85 cases(86 eyes; 74.1%)were positive for bacterial culture. A total of 111 bacterial strains were cultured, which contained 26 types of bacteria. Among them, 32 strains were aerobic(28.8%); 26 strains were anaerobic(23.4%); and 53 strains were facultative anaerobic(47.7%). The most common bacteria were streptococcus(20 strains), staphylococcus(13 strains), Propionibacterium(10 strains), and capnocytophaga(10 strains). Only 4 cases(4 eyes; 3.4%)of microbial cultures were positive for Actinomyces. Fungus was negative in all microbial cultures. Treatment: Of the 119 cases(120 eyes), 114 cases(115 eyes; 95.8%)were cured by conservative treatment of removing lacrimal canaliculus stones through lacrimal punctum and intracanalicular ointment infiltration(IOI), while 5 cases(5 eyes)were not effective in conservative treatment; however, all of them were cured after surgical treatment, and the cure rate for primary canaliculitis was 100.0%.CONCLUSION: The incidence of primary canaliculitis is low, and it is prevalent in middle-aged and older female. Single lacrimal canaliculus is more common, which could be missed and misdiagnosed in clinic. Actinomyces is the major pathogen observed mostly in mixed infections, with heterogeneous strains, mainly anaerobic or facultative anaerobic bacteria. Streptococcus and Staphylococcus are the most common whereas fungal canaliculitis is rare. The cure rate of primary canaliculitis is high after diagnosis, and IOI method is recommended as the initial treatment of canaliculitis.

Differential diagnosis of adult-onset Still's disease with other fever of unknown origin causes / 解放军医学杂志

Objective To explore the differential diagnostic indicators of adult-onset Still's disease(AOSD)from other fever of unknown origin(FUO).Methods The clinical data and laboratory indicators of 177 AOSD patients and 163 FUO patients who were hospitalized in the First Affiliated Hospital of Army Medical University from January 2010 to May 2021 were collected,and the patients were randomly divided into training group and verification group.Statistically significant variables were extracted from univariate analysis for receiver operating characteristic(ROC)curve analysis and the best cut-off value of the variables was obtained.The differential diagnostic indicators were extracted by multivariate logistic regression analysis and nomogram model was constructed.ROC curve,calibration curve,and decision curve analysis were used to evaluate the accuracy and stability of nomogram.Results Univariate analysis revealed that there were significant differences in 4 clinical features(arthralgia,rash,pharyngeal pain,myalgia)and 14 laboratory parameters[white blood cell count(WBC),monocyte percentage,neutrophil percentage,lymphocyte percentage,platelet count,C-reactive protein,interleukin-6(IL-6),ferritin,globulin,immunoglobulin A,and immunoglobulin G(IgG),creatine kinase,creatinine and complement C3].Multivariate analysis suggested that arthralgia,WBC≥9.995×109/L,IL-6≥98.13 ng/L,ferritin≥507.37 ng/ml,globulin≤36.58g/L,IgG≤13.59g/L,complement C3≥1.27 g/L were related with AOSD.The area under curve(AUC)values of training group and verification group were 0.917(95%CI 0.883-0.951)and 0.869(95%CI 0.802-0.936),respectively.The calibration curves showed good consistency.The decision curve analysis showed that training group and verification group had a large positive rate of return in the wide risk range of 5%-85%and 10%-85%,respectively.Conclusions This study has established a relatively accurate AOSD differential diagnosis model.The combination of arthralgia,WBC,IL-6,ferritin,globulin,IgG and complement C3 may help to distinguish AOSD from other causes of FUO.

Comparative study on clinical characteristics of cardiogenic and non-cardiogenic cardiac arrest patients out-of-hospital based on Utstein style / 中华急诊医学杂志

Objective:To analyze the causes of out-of-hospital cardiac arrest (OHCA) and the differences in outcomes of pre-hospital first-aid measures and cardiopulmonary resuscitation for different etiologies, improved the success rate of rescue.Methods:A retrospective study was conducted on OHCA patients admitted to Beijing Emergency Medical Centre from January to December 2021. The pre-hospital emergency medical records and rescue results within medical institutions were collected. Compared the basic situation between patients with cardiogenic and non-cardiogenic cardiac arrest, the differences of rescue measures and CPR outcomes between the groups were compared by non-parametric test and χ 2 test. Results:A total of 7 517 patients were included in this study. Cardiogenic arrest patients were older, more underlying diseases (84.2%), and cardiac arrest mainly occurred at home. The cause of non-cardiogenic arrest included disease (85.1%), trauma (2.9%), suicide (5.0%), traffic accidents (1.7%), poisoning (1.1%), and so on. In terms of first-aid measures, after the emergency doctor arrived at the scene, the proportion of first-aid measures used for cardiogenic patients was high (22.3%), and the first aid measures include cardiopulmonary resuscitation, tracheal intubation, defibrillation, oxygen inhalation, injection of adrenaline and use of other drugs. All the proportions of first-aid measures for cardiogenic patients were significantly higher than non-cardiogenic patients (all P<0.001). In terms of clinical outcomes, there were no statistical differences in return of spontaneous circulation ( P=0.072) and 24-hour survival ( P=0.093) between cardiogenic and non-cardiogenic patients. Conclusions:Cardiogenic cardiac arrest was the main cause of OHCA. Cardiogenic arrest patients were more underlying diseases, and older in age, the main clinical feature was onset at home. The comprehensive treatment measures for pre-hospital first-aid cardiac arrest should continue to be strengthened to improve the success rate of rescue for OHCA.

Etiology and outcome of new-onset status epilepticus in older patients / 临床神经病学杂志

Objective To investigate the etiology and outcome of elderly patients with new-onset status epilepticus(NOSE).Methods According to the electronic medical record,the keywords"Epilepsy"and"Status epilepticus"were searched for elderly patients with status epilepticus admitted to Sichuan Provincial People's Hospital between January 2018 and June 2023.Elderly patients with NOSE were strictly screened according to inclusion and exclusion criteria,and etiology were analyzed according to medical history and ancillary examinations,and factors related to prognosis of epilepsy were analyzed by Logistic regression.Results There were 63 elderly NOSE patients,including 38 males and 25 females,with an average age of(72.71±7.45)years old.Cerebrovascular disease(21%)was determined as the major cause of NOSE in elderly patients,followed by central nervous system infection(17%).Logistic regression analysis of prognostic factors showed that co-infection(OR = 11.67,95%CI:1.391-97.850,P =0.024)and renal insufficiency(OR =18.90,95%CI:3.522-101.43,P = 0.001)were associated with poor patient prognosis.Conclusions Cerebrovascular disease is the main known cause of NOSE in elderly patients.Prevention of infection and improvement of renal function may improve prognosis.

Bone metabolism in patients with osteonecrosis of the femoral head based on etiology and Association Research Circulation Osseous staging / 中国组织工程研究

BACKGROUND:Currently,there is a lack of large sample studies to analyze the bone metabolism level of patients with femoral head necrosis of different etiologies and stages,which is not conducive to the development of better necrosis-promoting repair strategies. OBJECTIVE:To study the bone metabolism of patients with osteonecrosis of the femoral head with different etiologies and Association Research Circulation Osseous(ARCO)stages. METHODS:A retrospective study was performed on 401 patients diagnosed with osteonecrosis of the femoral head as the trial group,and 81 healthy subjects as the control group.The trial group could be divided into three groups according to different etiologies:steroid-induced osteonecrosis of the femoral head,alcoholic osteonecrosis of the femoral head and traumatic osteonecrosis of the femoral head,and were divided into stages Ⅱ/Ⅲ/Ⅳ according to different ARCO stages.Seven bone metabolism-related indicators of all subjects were collected,including bone metabolism-regulating hormone 25-hydroxyvitamin D and bone conversion markers:N-terminal propeptide of type Ⅰ procollagen,degradation product of type Ⅰ collagen,n-terminal middle molecular fragment of osteocalcin,general biochemical markers of bone metabolism:serum calcium,serum phosphorus,serum alkaline phosphatase.The bone metabolism levels of each group were compared and the independent factors associated with osteonecrosis of the femoral head were determined by binary Logistic regression analysis. RESULTS AND CONCLUSION:Compared with the control group,levels of degradation product of type Ⅰ collagen,N-terminal propeptide of type Ⅰ procollagen,n-terminal middle molecular fragment of osteocalcin,serum phosphorus and alkaline phosphatase in the trial group were significantly increased(all P＜0.05).Based on the presence or absence of the disease,according to binary Logistic regression analysis,degradation product of type Ⅰ collagen,N-terminal propeptide of type Ⅰ procollagen,and n-terminal middle molecular fragment of osteocalcin were independent factors associated with osteonecrosis of the femoral head.The levels of degradation product of type Ⅰ collagen and N-terminal propeptide of type Ⅰ procollagen in three groups of patients with different etiologies were higher than normal reference values.The bone metabolism-regulating hormone 25-hydroxyvitamin D and serum calcium in the alcoholic osteonecrosis of the femoral head group were higher than those in the other two groups(P＜0.05).The level of bone metabolism-regulating hormone 25-hydroxyvitamin D in steroid-induced and traumatic osteonecrosis of the femoral head groups was lower than the normal value.There were no significant differences in seven bone metabolism-related indicators in patients with ARCO stages Ⅱ,Ⅲ and Ⅳ osteonecrosis of the femoral head(all P＞0.05),but degradation product of type Ⅰ collagen and N-terminal propeptide of type Ⅰ procollagen in these three groups were higher than normal reference values.Bone metabolism-regulating hormone 25-hydroxyvitamin D in patients with ARCO stage Ⅱ and ARCO stage Ⅳ was lower than the normal reference value.It is concluded that the bone metabolism level of osteonecrosis of the femoral head patients was abnormal.The degradation product of type Ⅰ collagen and N-terminal propeptide of type Ⅰ procollagen of osteonecrosis of the femoral head patients with different etiologies and ARCO stages were all higher than the normal reference value,and they were in a state of high bone turnover.Degradation product of type Ⅰ collagen,N-terminal propeptide of type Ⅰ procollagen and n-terminal middle molecular fragment of osteocalcin may be risk factors for the pathogenesis of osteonecrosis of the femoral head.

Free vascularized fibular grafting in treatment of femoral head osteonecrosis / 中国组织工程研究

BACKGROUND:Free vascularized fibular grafting is an effective hip preservation treatment for femoral head osteonecrosis,but its influencing factors are still controversial. OBJECTIVE:To explore the clinical efficacy of free vascularized fibular grafting for femoral head osteonecrosis,and the influence of the etiology and severity of femoral head osteonecrosis on its efficacy. METHODS:Clinical data and clinical efficacy scores of preoperative and postoperative hip joints in 63 patients with femoral head osteonecrosis(73 cases of hip)were enrolled.The subjects were divided into three groups by the etiological classification criteria of femoral head osteonecrosis,including glucocorticoid-associated,alcohol-associated,and idiopathic groups,and also were divided into three groups by the Ficat classification system,including Ficat Ⅱ,Ficat Ⅲ and Ficat Ⅳ groups.The effects of etiological classification and lesion degree on the clinical efficacy of free vascularized fibular grafting for femoral head osteonecrosis were analyzed. RESULTS AND CONCLUSION:(1)The visual analog scale scores in all periods after free vascularized fibular grafting for femoral head osteonecrosis were significantly decreased compared with preoperative data(P<0.001),and Harris scores were significantly increased compared with preoperative data(P<0.001).(2)In the glucocorticoid-associated,alcohol-associated,and idiopathic groups,except the glucocorticoid-associated group,postoperative Harris scores were significantly increased 2 and 3 years after surgery in other groups compared with preoperative data(P<0.05).(3)In the three groups of Ficat Ⅱ,Ficat Ⅲ,and Ficat Ⅳ,the postoperative Harris scores of Ficat Ⅱ and Ficat Ⅲ groups were significantly increased compared with preoperative data(P<0.05),while the difference was not significant in the Ficat Ⅳ group between the preoperative and postoperative data(P>0.05).(4)These results indicate that the clinical effect of free vascularized fibular grafting for the femoral head osteonecrosis is significant,which can reduce hip pain and improve hip joint function.It may not be affected by the etiology,but by the severity of the femoral head osteonecrosis.

Objective To analyze the epidemiological characteristics of hand-foot-mouth disease(HFMD)in Gan-zhou.Methods The epidemiological data of HFMD reported by the Infectious Disease Surveillance System,a sub-system of China Disease Prevention and Control Information System,from 2017 to 2020 were analyzed by descriptive methods.Enterovirus(EV)nucleic acid and typing detections via throat swabs,anal swabs or herpes fluid of patients was detected by real-time fluo-rescent polymerase chain reaction.The change in HFMD epidemic characteristics was compared between 2020 and 2017-2019.Results The incidence of HFMD in Ganzhou in 2020 was significantly lower than that from 2017 to 2019(x2=50.587,P＜0.05).In 2020,the incidence of HFMD in counties and districts of Ganzhou(except Huichang County)signifi-cantly decreased compared with that in 2017-2019(P＜0.05).From 2017 to 2019,the incidence of HFMD was obviously seasonal,with a high incidence in summer and autumn,and two significant incidence peaks were formed in June and September in 2017 and 2018,respectively.In 2019,there was a summer peak in June.The epidemic trend in 2020 was different,with a very low epidemic trend in summer and autumn,and a peak in winter.The incidence of HFMD in men,women and all ages in 2020 significantly decreased compared with that in 2017-2019(P＜0.05),and the age of onset was mainly distributed in 1-5 years,especially in children aged 1 to 3 years.There was a significant difference in the incidence of HFMD among different ages(P＜0.05).The positive rate of EV in Ganzhou in 2020 was lower than that from 2017 to 2019(x2=47.273,P＜0.05).The positive rate of EV in January,March to September in 2020 was significantly lower,and the positive rate of EV in November,December 2020 was significantly higher than that in the same period in 2017 to 2019(P＜0.05).Strain CA16 showed an increasing trend year by year from 2017 to 2019,and became the dominant strain in 2019.The proportion of patients infected with CA6 strain was on the fise from 2018 to 2020,and CA6 became the dominant strain in 2020.Conclusion The HFMD in Ganzhou has obvious population characteristics and seasonality,and the pathogen spectrum is constantly changing.

Discussion on Etiology and Pathogenesis of Recurrent Spontaneous Abortion Caused by Immune Factors Based on"Latent Toxic Hiding in Membrane" / 中国中医药信息杂志

Immune factors play an important role in recurrent spontaneous abortion(RSA),and immune imbalance affects embryo implantation,growth,and development.There is currently no consensus on the etiology and pathogenesis of RSA caused by immune factors.Based on the theory of latent toxic in TCM and combined with the pathological mechanism of the dynamic changes of immune abnormal substances in the body,this article proposed that latent toxic is the key cause of RSA caused by immune factors.Furthermore,it expounded the pathogenic characteristics of latent toxic:combination of heat and blood stasis hidden in the womb,and latent toxic plays a role in embryo formation under qi deficiency conditions.It is established that latent toxin stagnation in the membrane is the pathogenic mechanism.Moreover,this article revealed the variable pathological changes such as the blockage of the inner membrane system and the outer membrane system.Treatment should be based on the basic methods of tonifying qi and nourishing blood,tonifying kidney to secure the Thoroughfare Vessel,clearing heat and cooling blood,promoting blood circulation and removing blood stasis.This article could provide a theoretical basis for TCM syndrome differentiation and treatment of RSA caused by immune factors.

Discussion on the Treatment of Bronchiectasis Based on the Theory of Incubative Pathogenic Factors / 中国中医药信息杂志

Bronchiectasis has the characteristics of long course,gradual aggravation,easy recurrence and difficult to treat.The characteristics are similar to those arouse by incubative pathogenic factors.Based on the theory of incubative pathogenic factors,this disease is often related to the incubative pathogenic factors in the body's areas with deficient healthy qi,which occur at regular times.The etiology can be external,congenital,or internal.Treatment should focus on different characteristics of incubative pathogenic factors.Attention should be paid to clearing and dispersing in external pathogenic factors,while attention should be paid to supporting and promoting healthy qi in congenital pathogenic factors,and do not forget to remove internal pathogenic factors.

Research progress in etiology of acute gallstone pancreatitis / 中华肝胆外科杂志

Acute gallstone pancreatitis (AGP) is a kind of acute pancreatitis caused by gallstones. The etiology of AGP is complex, and the anatomic basis and initiating factors have a synergistic effect on its pathogenesis, which needs to be studied jointly. The way of the confluence of pancreaticobiliary ducts, dilated main pancreatic duct, the relatively narrow opening of duodenal papilla and small stones or microlithiasis may be involved in the pathogenesis of AGP, in which small stones are the most important. Etiological diagnosis and clinical treatment of AGP should be carried out simultaneously. The timely selection of treatment methods for different causes can alleviate the patient's condition to the greatest extent and reduce the cost of treatment. At present, it is difficult to unify the prediction indexes of AGP. Meanwhile, the pathogenesis and related prophylaxis and treatment also need to be studied. In this paper, the anatomic basis, initiation factors, pathogenesis and self-defense of AGP were analyzed to provide a new perspective for its treatment.
