Maxillofacial Fractures in Pondicherry, India: An Eight?Year Single Centre Retrospective Study

Background: The purpose of the present study was to analyze the etiology, incidence, pattern, and treatment modalities of patients with maxillofacial fractures treated at the Department of Dentistry of a medical college in Pondicherry during the period between June 2011 and June 2019. Materials and Methods: A retrospective epidemiological study of 277 patients treated for maxillofacial fractures between June 2011 and June 2019 was performed. Data regarding age, gender, etiology, site of the fracture, time of injury, presence of associated injuries, treatment modalities, and complications were recorded. Results: A total of 491 maxillofacial fractures were seen in 277 patients. These were 261 males (94.2%) and 16 females (5.8%) with a male to female ratio of 16.3:1. Most of the patients 79.8% were in the age group of 11 to 40 years. Most common cause of injury was Road Traffic Collisions (RTCs; 62.1%), followed by fall (20.2%), assault (14.4%) and others (3.3%). Fractures of the mandible (52.3%) and zygomatic complex (18.9%) were the most common maxillofacial fractures reported in our study. 196 patients sustained associated injuries with a prevalence of soft tissue injury (61.2%). Majority of fractures were treated with open reduction and internal fixation (ORIF; 71.9%) of patients followed by closed reduction (17.7%) and observation only (10.4%). Postoperative complications were presented in 16.8% of the patients in the study. Conclusion: RTC is the commonest cause of maxillofacial injury with a male predominance in our study. Mandibular and zygomatic complex fractures were the most common. ORIF remains the preferred method of treatment.

HISTOPATHOLOGY OF GALLBLADDER SPECIMENS AFTER CHOLECYSTECTOMY: A RETROSPECTIVE STUDY

Background Current approach to detect the presence of gallbladder carcinoma involves a routine histopathological examination of all gallbladder specimens, regardless of the clinical characteristics of the patient or macroscopic aspect of the gallbladder. Available pathological reports were interpreted for the following parameters: age, gender, and pathological diagnosis. In addition, the demographic information and clinicopathologic characteristics of the patients with histopathologic findings were assessed in detail, and re-examination of the available specimens was done. Inpatient records of the Methods patients who had been operated for elective and emergency cholecystectomies in the hospital associated with Khaja Bandanawaz University – Faculty of medical Sciences; from January 2018 to November 2022, were retrospectively evaluated. Results A total of 661 gallbladder specimens submitted for histopathological examination during the study period were included in the study. The results of histopathological examination of these gallbladder specimens showed that chronic cholecystitis was found in 535 (81%), acute cholecystitis in 46 (6.99%), cholesterolosis in 44 (6.5%) patients, Dysplasia was found in 34 (5.14%) patients, and gallbladder carcinoma was detected in 2 (0.30%) patients. Conclusion A strategy of selective approach for histopathological examination of gallbladder specimens may be safe in areas with very low incidence of gallbladder carcinoma. Such selective strategy is more cost-effective, reduces the workload of pathologists, and does not appear to compromise patient outcome.

Retrospective study on the types and characteristics of shock in polytrauma patients at different stages after trauma / 中华急诊医学杂志

Objective:To investigate the types, incidences, and clinical characteristics of shock in polytrauma patients at different stages after polytrauma.Methods:A retrospective study was conducted on polytrauma patients admitted to multiple trauma centers from June 2020 to December 2021. The inclusion criteria were patients >18 years old and treated due to polytrauma. Exclusion criteria included an admission time of more than 48 h after trauma, a history of malignancy, or metabolic, consumptive, and immunological diseases. The early stage was defined as the period of ≤48 h after polytrauma, and the middle stage was defined as the period between 48 h and 14 days. The patient’s medical history, clinical manifestations, laboratory tests, imaging examination, injury severity score (ISS), and Glasgow coma scale (GCS) were collected. The types, incidences, and clinical characteristics of shock in different stages after polytrauma were analyzed, according to the diagnostic criteria of each type of shock. The differences between the groups were compared by Student’s t test, χ2 test or Mann-Whitney U test. Results:The incidence of the early and middle stage shock after polytrauma were 73.1% and 36.4%, respectively, with statistically significant difference between stages ( P<0.01). There were significant differences in the incidence of hypovolemic shock (83.6% vs. 28.4%), distributed shock (13.7% vs. 80.9%) and cardiogenic shock (3.5% vs. 6.6%) between stages (all P<0.05). The incidence of obstructive shock (8.4% vs. 9.7%, P>0.05) was similar between stages. The incidence of undifferentiated shock was 1.6% and 1.2%, respectively. There were 9.5% patients with multifactorial shock in the early stage and 14.4% in the middle stage. Totally 7 combinations of multifactorial shock were found in different stages after polytrauma. In the early stage, the combination of HS and DS accounted the highest ratio (42.3%) and followed by HS and OS for 28.8%. In the middle stage, the combination of HS and DS was the most common (48.6%) and followed by DS and OS (24.3%). Conclusions:The incidence of shock in polytrauma patients is high. Different types of shock can occur simultaneously or sequentially. Therefore a comprehensive resuscitation strategy is significant to improve the success rate of treatment.

Analysis of risk factors for delirium in critically ill patients in a psychiatric hospital： a retrospective study / 四川精神卫生

BackgroundThe incidence of delirium in critically ill psychiatric patients is high， and there are many factors affecting delirium occurrence. At present， epidemiological studies on delirium among critically ill patients in psychiatric hospitals are limited. ObjectiveTo explore the risk factors for delirium in critically ill patients in a psychiatric hospital， so as to guide the clinical management of delirium in psychiatric hospitals. MethodsThis retrospective study included 427 critically ill patients who were admitted to Shenzhen Kangning Hospital from January 1， 2019 to May 31， 2021. The delirium situation， gender， age， pre-admission course of illness （duration from the onset of acute mental state changes to in-patient registration at a psychiatric hospital）， history of mental illness， history of cognitive dysfunction， history of using psychoactive substances， history of using sedative and hypnotic drugs， number of combined chronic diseases， number of combined drugs and type of disease were examined as potential risk factors for delirium. Single Logistic regression was used to analyze the potential risk factors for delirium， and the potential risk factors were incorporated into the multi-factor Logistic regression analysis model so as to gradually screen out the risk factors for delirium in critically ill psychiatric patients. ResultsDelirium was present in 33.49% （143/427） of critically ill patients. Multi-factor Logistic regression analysis demonstrated that the presence of delirium was associated with mental and behavioral disorders caused by psychoactive substances （OR=8.949， P<0.01）， absent history of mental illness （OR=4.202， P<0.01）， number of combined chronic diseases （OR=1.249， P<0.01）， age （OR=1.031， P<0.01） and pre-admission course of illness （OR=0.942， P<0.01） . ConclusionDelirium was present in nearly 1/3 critically ill patients in the psychiatric hospital. The risk factors for delirium included short course of illness before admission， age， more combined chronic diseases， absent history of mental illness， mental and behavioral disorders caused by psychoactive substances. ［Funded by Shenzhen Fund for Guangdong Provincial High-level Clinical Key Specialties （number， SZGSP013）］

Adolescent Female Victims of Sexual Violence: Analysis of Loss of Follow-up after Emergency Care and Outpatient Follow-up / Meninas adolescentes vítimas de violência sexual: Análise da falta de atendimento de emergência e seguimento ambulatorial

Abstract Objective To assess the loss to follow-up after emergency care and during 6-months of outpatient follow-up, and the associated variables, among adolescent sexual violence survivors. Methods This is a retrospective study with review of the medical records of 521 females, aged 10 to 18 years, who received emergency care in a referral service in São Paulo, Brazil. The variables were sociodemographic; personal history; characteristics of abuse, disclosure, and reactions triggered after abuse (physical and mental disorders as well as social changes), psychotropic prescription needs, and moment of abandonment: after emergency care and before completing 6 months of outpatient follow-up. To compare groups of patients lost to follow-up at each time point, we used the Chi-square and Fisher exact tests followed by multiple logistic regression with stepwise criterion for selection of associated variables. We calculated the odds ratio with confidence interval (OR, CI 95%). The level of significance adopted was 5%. Results A total of 249/521 (47.7%) adolescents discontinued follow-up, 184 (35.3%) after emergency care and 65 (12.4%) before completing outpatient follow-up. The variables of living with a partner (OR = 5.94 [CI 95%; 2.49-14.20]); not having a religion (OR = 2.38 [CI 95%;1.29-4.38)]), having a Catholic religion [OR = 2.11 (CI 95%; 1.17-3.78)]; and not disclosing the abuse [OR = 2.07 (CI 95%; 1.25-3.44)] were associated with loss to follow-up after emergency care. Not needing mental disorder care (OR = 2.72 [CI 95%; 1.36-5.46]) or social support (OR = 2.33 [CI 95%; 1.09-4.99]) were directly associated with loss to outpatient follow-up. Conclusion Measures to improve adherence to follow-up should be aimed at adolescents who live with a partner and those who do not tell anyone about the violence.

Resumo Objetivos Avaliar a perda de seguimento de adolescentes vítimas de violência sexual após o atendimento de emergência, durante o seguimento ambulatorial e as variáveis associadas. Métodos Estudo retrospectivo com a revisão de prontuários de 521 mulheres de 10 a 18 anos, que buscaram atendimento de emergência em um serviço de referência em São Paulo, Brasil. As variáveis foram sociodemográficas; antecedentes pessoais; características do abuso, atitude de revelação e reações desencadeadas após o abuso (distúrbios físicos, mentais e mudanças sociais), necessidades de prescrição de psicotrópicos e momento do abandono: após atendimento de emergência e antes de completar 6 meses de seguimento ambulatorial. Para comparar os grupos de perda de seguimento em cada momento, foram utilizados os testes do qui-quadrado e exato de Fisher, seguidos de regressão logística múltipla com critério stepwise para seleção das variáveis associadas. Calculamos a razão de probabilidade com intervalo de confiança (RP, IC 95%). O nível de significância adotado foi de 5%. Resultados Um total de 249 (47,7%) das adolescentes descontinuaram o acompanhamento, 184 (35.3%) após o atendimento de emergência e 65 (12.4%) antes de completar o seguimento ambulatorial. As variáveis de viver com companheiro [RP = 5,94 (IC 95%; 2,49-14,20]; não ter religião [RP = 2,38 (IC 95%;1,29-4,38)], ter religião católica [RP = 2,11 (IC 95%; 1,17-3,78)] e não revelar o abuso [RP = 2,07 (IC 95%; 1,25-3,44)] foram associadas à perda de seguimento após o atendimento de emergência. Não necessitar de cuidados de saúde mental (RP = 2,72 [IC 95%; 1,36-5,46]) ou apoio social (RP = 2,33 [IC 95%; 1,09-4,99]) foram as variáveis associadas à perda do seguimento ambulatorial. Conclusão Medidas para melhorar a adesão ao seguimento devem ser direcionadas às adolescentes que vivem com parceiro e às que não revelam a violência sofrida.

Asociación entre tiroiditis linfocítica crónica y carcinoma papilar de tiroides: Revisión sistemática y metaanálisis de estudios en especímenes quirúrgicos / Association between chronic lymphocityc thyroiditis and papillary thyroid carcinoma: Systematic review and meta-analysis of studieson surgical specimens

Introducción. Existen resultados inconsistentes con relación al planteamiento de la hipótesis que sugiere una mayor probabilidad de documentar un carcinoma papilar de tiroides en especímenes quirúrgicos con cambios compatibles con tiroiditis linfocítica crónica. En los metaanálisis existentes se han incluido estudios no comparables metodológicamente y no se proponen claras fuentes de sesgo, justificación para la realización del presente metaanálisis. Métodos. Se realizó una búsqueda bibliográfica en Pubmed y Embase. Fueron obtenidos estudios retrospectivos donde se comparaba la prevalencia de carcinoma papilar de tiroides en especímenes con y sin cambios por tiroiditis linfocítica crónica. La evidencia recolectada fue sintetizada estadísticamente. Resultados. Un total de 22 artículos fueron incluidos. La población estuvo conformada por 63.548 especímenes. El OR combinado fue 1,81 (IC95%: 1,51-2,21). Hubo heterogeneidad entre la distribución de las razones de oportunidad entre los estudios (I2= 91 %; p>0,00001). La forma del gráfico en embudo de los estudios incluidos en el análisis parece estar simétrica, lo que indica la ausencia del sesgo atribuible a los estudios pequeños. Conclusiones. La literatura actual sugiere que existe un mayor riesgo de documentar un carcinoma papilar de tiroides en especímenes quirúrgicos en los que se observan cambios compatibles con tiroiditis linfocítica crónica; sin embargo, existen fuentes de sesgo que no será posible controlar en estudios retrospectivos, por lo que recomendamos estudiar la hipótesis que sugiere una mayor probabilidad de diagnosticar un carcinoma papilar de tiroides en especímenes con cambios compatibles con tiroiditis linfocítica crónica mediante metodologías prospectivas

Introduction. Inconsistent results exist in the literature regarding the hypothesis statement suggesting an increased likelihood of documenting papillary thyroid carcinoma (PTC) in surgical specimens with changes compatible with chronic lymphocytic thyroiditis. Existing meta-analyses have included studies that are not methodologically comparable and do not propose clear sources of bias, thus, this is justification for the present meta-analysis. Methods. A literature search in Pubmed and Embase was performed from January 1, 1950 to December 31, 2020. Retrospective studies comparing the prevalence of papillary thyroid carcinoma in specimens with and without chronic lymphocytic thyroiditis changes were obtained. The collected evidence was statistically analyzed. Results. A total of 22 articles were included. The study population consisted of 63,548 surgical specimens. The pooled OR, based on the studies, was 1.81 (95% CI: 1.51-2.21). There was heterogeneity between the distribution of prevalence ratios and opportunity ratios across studies (I²= 91%; p>0.00001). The funnel plot shape of the studies included in the analysis appears to be symmetrical, indicating the absence of bias attributable to small studies. Conclusions. The current literature suggests that there is an increased risk of documenting papillary thyroid carcinoma in surgical specimens in which chronic lymphocytic thyroiditis-compatible changes are observed; however, there are sources of bias that will not be possible to control for in retrospective studies, so we recommend studying the hypothesis suggesting an increased likelihood of diagnosing PTC in specimens with chronic lymphocytic thyroiditis-compatible changes using prospective methodologies

A retrospective study of risk factors of Mucormycosis in COVID-19 patients at a dedicated COVID hospital

Background: In the present scenario treating Mucormycosis is proving more challenging than COVID-19. Aim and Objectives: To describe the demographic profile, clinical presentations, and risk factors of COVID-19 associated Mucormycosis. Materials and Methods: A retrospective cross-sectional study was conducted in 30 patients. Diagnosed cases of Mucormycosis with a history of RTPCR or Rapid antigen positive for COVID infection were included in the study. Patients with a past history of Mucormycosis infection or patients not admitted in the hospital were excluded. The study began after obtaining the Institutional Ethical Committee Approval. The statistical analysis was done to study the Percentage distribution of the risk factors. Results: About 66.66% patients were male and 33.33% were females. The age of the patients was 52.8 � 10.3 years. About 76.66% patients were farmers/farm workers. 90% of cases had Maxillary, 25 % Ethmoid and 5% had Sphenoid sinus involved. 23.33% were known diabetic. About 63.33% were having uncontrolled blood glucose level. About 23.33% were known hypertensive. About 66.66% had received steroids, 56.66% required oxygen therapy. 36.66% required Intensive care unit (ICU) and 6.66% required ventilator support during their management of acute COVID infection. None were fully vaccinated for COVID-19. Conclusion: The males are more susceptible to post-COVID 19 Mucormycosis infection as compared to females. Farmers/farm workers are at an increased risk too. Over use of steroids, uncontrolled blood sugar levels, oxygen therapy, long hospital stay, and ICU procedures and ventilators also contribute to the increased occurrence of post-COVID Mucormycosis. Most important factor that was observed was all the patients suffering from post-COVID Mucormycosis were not vaccinated.

Clinical diagnosis and treatment of primary thyroid tuberculosis: a retrospective study

ABSTRACT BACKGROUND: Primary thyroid tuberculosis (PTT) is an uncommon type of extrapulmonary tuberculosis, which is caused by Mycobacterium tuberculosis. It does not have specific clinical manifestations, and most cases are diagnosed through postoperative histopathological examination. OBJECTIVE: To evaluate the diagnostic pattern and management strategy among patients with primary thyroid tuberculosis. DESIGN AND SETTING: Retrospective study on patients with primary thyroid tuberculosis in the First Hospital of Jilin University (Changchun, China). METHODS: Between March 2015 and June 2020, nine cases of PTT were diagnosed and treated in the Department of Thyroid Surgery of the First Hospital of Jilin University. Age at diagnosis, primary symptoms, preoperative biopsy, operation method, pathological classification, acid-fast staining test, anti-TB therapy and prognosis were registered in order to explore the appropriate protocol for diagnosis and treatment of this disease. RESULTS: None of the patients was diagnosed with thyroid tuberculosis before surgery. All the patients underwent surgery. Granulomatous changes or caseous necrosis in thyroid tissue were found through postoperative histopathological evaluation. Polymerase chain reaction (PCR) results for Mycobacterium tuberculosis were positive in all patients. Most patients had a good prognosis after surgery and anti-tuberculosis drug therapy. CONCLUSION: PTT is a rare disease. It is important to improve the preoperative diagnosis. Preoperative diagnostic accuracy relies on increased awareness of the disease and appropriate use of preoperative diagnostic methods, such as PCR detection, fine-needle aspiration cytology, acid-fast bacillus culture, ultrasound and blood sedimentation. PCR detection of M. tuberculosis is recommended as the gold standard for diagnosis.

Sexual Violence Suffered by Women in Early and Late Adolescence: Care Provided and Follow-Up / Violência sexual sofrida por mulheres na adolescência precoce e tardia: Cuidado dispensado e seguimento

Abstract Objective To compare the sexual violence suffered by women in early and late adolescence, the reactions triggered after the aggression, and the care provided. Methods A retrospective study in which we reviewed the medical records of 521 female adolescents treated by a multidisciplinary team at a reference hospital in the city of Campinas, state of São Paulo, Brazil. We analyzed sociodemographic variables, and those pertainin to the characteristics of the episodes of violence, the emergency care, and the physical and psychological reactions observed during the follow-up. For the analysis, the sample was divided into groups of early (10 to 14 years) and late (15 to 18 years) adolescence. We used the Chi-squared/Fisher Exact, Mann-Whitney, and Kruskal-Wallis tests to compare the groups; the level of significance adopted was 5%. Results The early group (n= 242) contained more adolescents who were enrolled in school (p< 0.001), suffered more daytime aggressions (p= 0.031), in their residences (p< 0.001), by an aggressor with whom they were acquainted (p< 0.001), had greater need of legal protection (p= 0.001), and took longer to seek care (p= 0.048). Feelings of guilt, shame, and the perception of violence were similar between the groups. In the late group (n= 279), there was greater consumption of alcohol during the aggression (p= 0,005); they received significantly more prophylaxis treatments; reported more physical symptoms (p= 0.033), sleep disorders (p= 0.003), symptoms of anxiety (p= 0.045), and feelings of anguish (p= 0.011); and had more prescriptions of psychotropics (p= 0.005). Only 52% completed the 6-month follow-up, with no differences between the groups. Conclusion The age groups showed differences in the characteristics of the episodes of violence; early adolescents took longer to seek help, and the late group presented more intense symptoms and psychological worsening during the follow-up. Measures of prevention and specific care aimed at this population are needed.

Apenas 52% completaram o seguimento de 6 meses, sem diferenças entre os grupos. Conclusão Os grupos apresentaram diferenças nas características da violência; as adolescentes precoces chegaram mais tardiamente ao serviço, e o grupo tardio apresentou maior sintomatologia e piora psicológica no seguimento. São necessárias medidas de prevenção e cuidados específicos voltados a essa população.

A Contemporary Role of Beta Blockers in Myocardial Infarction

Myocardial infarction (MI) is characterized by plaque formation in the inner layer of arteries which occurs due to insufficient or complete cessation of oxygen supply in the myocardium. The common symptoms of MI are crushing or squeezing chest pain which radiates to the arms, shoulders, neck, or jaw, nausea, anxiety, restlessness, fear, heartburn, shortness of breath, cold sweat, fatigue, and dizziness. The treatment of this medical condition includes antiplatelet and thrombolytic therapy, painkillers (morphine or meperidine), diuretics and digitalis glycosides drugs. Moreover, nitroglycerin and antihypertensive drugs such as Beta-blockers, ACE inhibitors, or Calcium channel blockers may also be administered to reduce the blood pressure and improve the oxygen supply in the heart. Among them, beta blocker therapy has several beneficial properties such as it reduces myocardial oxygen demand, preventing arrhythmias, and improves ventricular remodeling, etc. However, there is no study on the role of only beta blocker therapy in the survival of MI patent is found to date. Thus, the present study focused on the evidence-based validation of Beta blocker therapy in the treatment and survival of MI patients. The retrospective study was conducted on 51 MI patients under the observation of medical practitioners. 100% of patients with MI showed a good recovery as well as survival percentage with Beta blocker therapy. This study finally concluded that beta blocker therapy is a safe and effective treatment for MI patients with negligible life-threatening medical conditions. Furthermore, a large group study is suggested with a number of health-related parameters for a better understanding of beta blocker as a first line of treatment for MI patients.

Clinical features and risk factor analysis of severe trauma patients with acute kidney injury / 中华急诊医学杂志

Objective:To investigate the clinical characteristics of the severe trauma patients with Acute kidney injury (AKI) ,and analyze the risk factors and clinical prognosis.Methods:Clinical data of severe trauma patients admitted to ICU of Xiaolan Hospital of Southern Medical University, from July 2018 to December 2020 were retrospectively analyzed. Demographic data, basic diseases, critical disease score, serum creatinine, hemoglobin, treatment options, blood transfusion volume, and clinical outcomes were collected to establish a clinical database. AKI was diagnosed and graded according to the Kidney Disease Improving Global Outcomes (KDIGO) criterion, and trauma type was classified according to the main injury part. The clinical data and laboratory examination of different groups were compared to analyze the clinical characteristics and prognosis in severe trauma patients. The risk factors of AKI in severe trauma patients were analyzed by Logistic regression.Results:(1) A total of 175 patients with severe trauma were eligible for inclusion, and the incidence of AKI was 30.9%(54/175), including 29 patients with AKI stage 1(16.6%), 15 patients with AKI stage 2 (8.6%), and 10 patients with AKI stage 3 (5.7%). In the cohort, the rate of in-hospital renal replacement therapy was 4%, in-hospital mortality was 5.7%, and 28-day mortality was 16.6%. (2) The age, shock patients, ICU admission serum creatinine, APACHEⅡscore and ISS score of AKI group were significantly higher than those of non-AKI group ( P<0.05). There were no significant differences between the two groups in gender, underlying diseases (hypertension and diabetes), ICU admission hemoglobin level and contrast agent utilization rate( P>0.05). Compared with the non-AKI group, AKI group had higher rates of surgical treatment (63% vs. 44.6%), more blood transfusion [875(720,1110)mL & 670(610,750)mL], longer ICU stay [6(4,11)d & 4(2.5,7.5)d], and higher rates of mechanical ventilation (96.3% vs. 81%), renal replacement therapy rate (13% vs. 0), in-hospital mortality (13% vs. 2.5%) and 28-day mortality (25.9% vs. 12.4%), the differences were statistically significant ( P<0.05). (3) The incidence of AKI was different in patients with different types of severe trauma, and the abdominal trauma group with a highest rate (50%). The serum creatinine at ICU admission and the peak value during hospitalization in abdominal trauma group were significantly higher than those in other injury types ( P<0.05). (4) Logistic regression analysis showed Age [ OR=1.020, 95% CI(1.003,1.038), P=0.024], APACHEⅡscore [ OR=1.137, 95% CI(1.053,1.228), P=0.001], shock [ OR=1.102, 95% CI(0.906,1.208), P=0.034], ICU admission serum creatinine [ OR=1.068, 95% CI(1.036,1.102), P=0.000], surgical treatment [ OR=4.205, 95% CI(1.446,12.233), P=0.008], blood transfusion volume [ OR=1.006, 95% CI(1.002,1.009), P=0.001] were independent risk factors for AKI in severe trauma patients. Conclusions:Severe trauma patients yield a high incidence of AKI influencing clinical prognosis. The incidence of AKI varies with different types of severe trauma. Age, APACHEⅡscore, shock, ICU admission serum creatinine, surgical treatment, and blood transfusion volume are independent risk factors for AKI in severe trauma patients.

Association between serum albumin level and prognosis in patients with scleroderma-associated interstitial lung disease / 中华全科医师杂志

Objective:To examine the association between baseline serum albumin level and short-term, long-term outcomes in patients with systemic sclerosis associated interstitial lung disease (SSc-ILD).Methods:A total of 259 patients with SSc-ILD who were hospitalized in West China Hospital of Sichuan University from January 2008 to December 2018 were enrolled. The data of serum albumin, demographic characteristics, peripheral blood hemoglobin at admission, and treatment plan were obtained from the hospital information management system, and the survival of the patients were followed up to June 1, 2019. The mean baseline serum albumin of 259 patients was 37.67 g/L, there were 118 patients with serum albumin ≤37.67 g/L (low protein group) and 141 patients with serum albumin>37.67 g/L (high protein group).Results:There were 64 males and 195 females with a mean age of 50.0(41.0, 61.0) years. The follow-up time was 627(61, 1 426) days. Compared to high protein group, the low protein group had higher proportion of male patients [30.5%(36/118) and 19.9%(28/141),χ 2=3.92, P=0.048], and higher levels of the erythrocyte sedimentation rate [45.0(27.0,69.0) vs. 29.0 (19.0,46.0)mm/1 h,χ 2=4.07, P<0.001], neutrophil percentage [71.50(63.35,77.13) vs. 65.60(59.50,72.50)%,χ 2=3.65, P<0.001], platelet [196(140,273) vs. 172(126,240)×10 9/L,χ 2=1.99, P=0.046], nutrophil/lymphocyte ratio [33.85(2.53,5.28) vs. 2.61(1.97,3.83),χ 2=4.57, P<0.001], platelet/lymphocyte ratio [149.0(112.0,216.8) vs. 113.5(72.76,158.8),χ 2=4.98, P<0.001], aspartate aminotransferase [27.0(21.0,39.0) vs. 23.0 (19.5,30.0) IU/L,χ 2=2.93, P=0.003], globulin [31.20(26.90,36.83) vs. 29.50(25.65,32.80) g/L,χ 2=2.28, P=0.023], serum cystatin C[1.14(0.98,1.33) vs. 1.02(0.88,1.16) mg/L,χ 2=3.80, P<0.001], IgA[2 710 (1 965,3 505) vs. 2 460 (1 862,3 105) mg/L,χ 2=2.13, P=0.033], IgG[15.05(12.83,21.08) vs. 13.60(11.53,17.23)g/L,χ 2=3.24, P=0.001], IgE[60.44(24.92,197.99) vs. 34.82(14.72,85.04) kIU/L,χ 2=3.33, P=0.001] and circulating immune complex [0.13(0.08,0.19) vs. 0.10(0.08,0.13)O.D,χ 2=2.60, P=0.009]; and lower levels of hemoglobin [121.5(101.8,132.0) vs. 129.0(119.0,142.0) g/L,χ 2=5.05, P<0.001], albumin [(33.28±3.49) vs.(41.34±2.95) g/L,χ 2=20.17, P<0.001] and IgM[1 320 (932,1 745) vs.1 560(1 170,2 030) mg/L, χ 2=2.63, P=0.009]. The utilization rate of antibiotics was higher in the low protein group (60 vs. 43 cases, χ 2=11.10, P=0.001). The number of patients followed up to 1, 5, and 10 years were 248, 245, and 244, respectively. The 1-year, 5-year, and 10-year cumulative survival rates of patients in low protein group and high protein group were(91.0% vs. 98.4%, χ 2=6.23, P=0.013;87.0% vs. 97.1%, χ 2=6.15, P=0.013; 81.6% vs. 97.1%, χ 2=7.00, P=0.008) respectively. Conclusions:Patients with scleroderma-associated interstitial lung disease have an increased risk of poorer prognosis when serum albumin ≤37.67 g/L.

A Retrospective Study on the Low Dose Lamotrigine of Skin Disorders / 医薬品情報学

Objective: In this study, we investigated the occurrence of skin damage following the initiation of low-dose lamotrigine.Methods: We retrospectively analyzed the incidence of skin disorders within 8 weeks of the start of lamotrigine administration, prescribing for 3 years from July 2014 to June 2016.In addition, we also confirmed the onset time of skin disorders in the low- and normal-dose groups.Results: The incidence of skin damage was 7.7 and 24.6 % in the low- and normal-dose lamotrigine start groups, respectively. The onset of skin disorders was relatively early in the normal-dose lamotrigine start group.On the other hand, no tendency was found in the low-dose lamotrigine start group because the number of cases was small.Conclusion: The initiation of low-dose lamotrigine and extension of introduction period might reduce the onset of early skin damage.

Risk factors of postoperative surgical site infection in colon cancer based on a single center database / 中华胃肠外科杂志

Objective: To explore the incidence and risk factors of postoperative surgical site infection (SSI) after colon cancer surgery. Methods: A retrospective case-control study was performed. Patients diagnosed with colon cancer who underwent radical surgery between January 2016 and May 2021 were included, and demographic characteristics, comorbidities, laboratory tests, surgical data and postoperative complications were extracted from the specialized prospective database at Department of General Surgery, Peking Union Medical College Hospital. Case exclusion criteria: (1) simultaneously multiple primary colon cancer; (2) segmental resection, subtotal colectomy, or total colectomy; (3) patients undergoing colostomy/ileostomy during the operation or in the state of colostomy/ileostomy before the operation; (4) patients receiving natural orifice specimen extraction surgery or transvaginal colon surgery; (5) patients with the history of colectomy; (6) emergency operation due to intestinal obstruction, perforation and acute bleeding; (7) intestinal diversion operation; (8) benign lesions confirmed by postoperative pathology; (9) patients not following the colorectal clinical pathway of our department for intestinal preparation and antibiotic application. Univariate analysis and multivariate analysis were used to determine the risk factors of SSI after colon cancer surgery. Results: A total of 1291 patients were enrolled in the study. 94.3% (1217/1291) of cases received laparoscopic surgery. The incidence of overall SSI was 5.3% (69/1291). According to tumor location, the incidence of SSI in the right colon, transverse colon, left colon and sigmoid colon was 8.6% (40/465), 5.2% (11/213), 7.1% (7/98) and 2.1% (11/515) respectively. According to resection range, the incidence of SSI after right hemicolectomy, transverse colectomy, left hemicolectomy and sigmoid colectomy was 8.2% (48/588), 4.5% (2/44), 4.8% (8 /167) and 2.2% (11/492) respectively. Univariate analysis showed that preoperative BUN≥7.14 mmol/L, tumor site, resection range, intestinal anastomotic approach, postoperative diarrhea, anastomotic leakage, postoperative pneumonia, and anastomotic technique were related to SSI (all P<0.05). Multivariate analysis revealed that anastomotic leakage (OR=22.074, 95%CI: 6.172-78.953, P<0.001), pneumonia (OR=4.100, 95%CI: 1.546-10.869, P=0.005), intracorporeal anastomosis (OR=5.288, 95%CI: 2.919-9.577,P<0.001) were independent risk factors of SSI. Subgroup analysis showed that in right hemicolectomy, the incidence of SSI in intracorporeal anastomosis was 19.8% (32/162), which was significantly higher than that in extracorporeal anastomosis (3.8%, 16/426, χ(2)=40.064, P<0.001). In transverse colectomy [5.0% (2/40) vs. 0, χ(2)=0.210, P=1.000], left hemicolectomy [5.4% (8/148) vs. 0, χ(2)=1.079, P=0.599] and sigmoid colectomy [2.1% (10/482) vs. 10.0% (1/10), χ(2)=2.815, P=0.204], no significant differences of SSI incidence were found between intracorporeal anastomosis and extracorporeal anastomosis (all P>0.05). Conclusions: The incidence of SSI increases with the resection range from sigmoid colectomy to right hemicolectomy. Intracorporeal anastomosis and postoperative anastomotic leakage are independent risk factors of SSI. Attentions should be paid to the possibility of postoperative pneumonia and actively effective treatment measures should be carried out.

Problems exposed in retrospective study of postoperative complications of rectal cancer and causal analysis / 中华胃肠外科杂志

Rectal cancer is a great threat to the health of the Chinese people. With the continuous improvement of surgical treatment level, complication as an important indicator to measure the safety of surgery has received increasing attention from clinicians both at home and abroad. Although there are many studies on postoperative complications of rectal cancer, the morbidity of complication reported by related studies varies greatly. An important reason occurs in the limitations of retrospective research, such as incomplete medical records, unclear diagnostic criteria for some complications, incomplete follow-up records after discharge, and poor communication mechanisms among MDT members. Starting from a retrospective study on postoperative complications of rectal cancer and finding out the defects and problems in the registration of complications in each center, then clarifying the definition of various postoperative complications, so as to establish a sound and standardized registration system, and carry out prospective research, this path could be a reliable method to obtain relatively accurate postoperative complications of rectal cancer.

Studies on Haemto-biochemical and Physiological Parameters in Canine Pyometra

Canine pyometra is an acute or chronic polysystemic diestrual disorder mainly of mature nulliparous bitches. In this retrospective study, an attempt was made to analyse the physiological and haemato-biochemical parameters of a total of 22 affected bitches attended at Sneh Vet lab and Clinic Bhadra, Bhiwani, (Haryana). The findings revealed pyrexia and tachycardia with normal respiration rate in most of the pyometra affected bitches. Amongst the haemato-biochemical parameters, there were reduced levels of haemoglobin, packed cell volume and total erythrocyte count, along with severe leucocytosis, neutrophilia with shift to left, lymphopenia, eosinophilia and elevated BUN and serum creatinine in the bitches affected with pyometra suggesting bone marrow and renal damage. However, the mean values of mean corpuscular volume, mean corpuscular haemoglobin as well as serum ALT and AST were within the normal range, confirming normocytic normochromic anaemia without liver dysfunction.

Male breast cancer: The Philippine General Hospital experience

RATIONALE/OBJECTIVE@#Breast cancer among males is often diagnosed at a later age and at an advanced stage. The study aimed to present the epidemiology, associated risk factors, clinical and pathological characteristics, treatment patterns and outcomes of male breast cancer patients treated at the Philippine General Hospital from January 2008- December 2017. Information from this study can provide for better understanding of the disease and basis for creating guidelines toward better outcomes. @*METHODS@#Retrospective study of medical records involving male breast cancer patients who underwent surgery and treatment at the Philippine General Hospital from January 2008- December 2017.@*RESULTS@#Male breast cancer accounted for 15 (0.26%) of 5,777 resected breast specimens for breast cancer patients with a 1:384 male to female ratio. The mean age of presentation was 60 years. The most common presentation was a retro-areolar mass, with 33% of patients presenting post-excision. Sixty-seven percent were at Stage II and 20% at Stage III. About 94% of patients have invasive ductal carcinoma, while the only other histology is papillary carcinoma at 13%. Majority of those tested were both estrogen receptor and progesterone receptor (ER/PR) positive (33% versus 1 %), and Her2neu negative. All patients underwent modified radical mastectomy. Only two patients were documented to have received adjuvant chemotherapy while one patient received neoadjuvant chemotherapy.@*CONCLUSION@#Breast cancer remains to be a rare disease among males, is often diagnosed at a later age and at an advanced stage. Because of its rarity, awareness is necessary not only in the community but also among healthcare providers to identify and treat the problem earlier. Further investigation and prospective studies are recommended.

Forensic Analysis of Sudden Death Associated with Sexual Activity / 法医学杂志

OBJECTIVES@#To analyze the characteristics of sudden death associated with sexual activity to provide recommendations for forensic identification.@*METHODS@#A retrospective analysis was conducted on autopsy cases accepted by Forensic Identification Center of Huazhong University of Science and Technology from 1998 to 2018, and a total of 15 cases of sudden death associated with sexual activity were screened out. The general information, case data and pathological changes of 15 cases were collected to find the relationship between sexual activity and sudden death.@*RESULTS@#The ratio of male to female was 1.5∶1. The average age of males was 50.1 years and that of females was 35.0 years. Coronary artery diseases and brain diseases accounted for most of the cases (12/15). Sexual partners were associated with locations of deaths and body dumping behaviors.@*CONCLUSIONS@#Sudden death associated with sexual activity, although rare, may occur in people over 30 years old with pre-existing heart or brain diseases, which should be paid attention to in forensic practice.
