Research progress on occupational hazards in lithium battery industry and their health risks / 环境与职业医学

Lithium batteries are widely used in energy storage, power, and other fields due to their advantages such as high performance and low cost. With the rapid development of the lithium battery industry, its production is constantly growing. However, the identification of occupational hazards and assessment of their health risks in lithium battery industry has rarely been reported. The composition of lithium batteries is complex and involves large numbers of compounds. Besides the traditional occupational hazards, workers may be exposed to many emerging chemicals throughout the production of raw materials, assembly and disassembly of lithium batteries. Therefore, this paper introduced the process chain of lithium battery production, analyzed the underlying occupational hazards in the industry, reviewed the health impacts of typical occupational hazards, and proposed the future research needs according to the current status of research on occupational exposure and health hazards in the lithium battery industry.

Comparative Analysis of Antimicrobial Efficacy of Electrolyzed Water with Sodium Hypochlorite Solution against Root Canal Pathogen: A Scoping Review

@#Electrolyzed water (EW) has been introduced as a surface disinfectant due to its antimicrobial properties without cytotoxic effects to oral tissues contrary to sodium hypochlorite (NaOCl), which is cytotoxic and can be detrimental if extruded beyond the root canal. This scoping review aimed to compare antimicrobial efficacy of EW with NaOCl on root canal pathogens and to assess effect of concentration and exposure time on antimicrobial efficacy. The review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews protocol guidelines. Electronic databases were searched for eligible articles published between 2011-2021 in PubMed, PLOS, Science Direct, and Google Scholar. Joanna Briggs Institute Critical Appraisal Tool was used for quality assessment. Of the 784 articles recovered, only 8 were eligible based on inclusion criteria. The included studies assessed several types of EW, which showed antimicrobial potential against E. faecalis in vitro in suspension and biofilm forms. EW demonstrated antimicrobial efficacy comparable with NaOCl in 5 of 8 studies. Only one study found that higher concentration and exposure time increased antimicrobial efficacy of EW; other studies showed otherwise. It can be concluded that EW can be a potential alternative solution for NaOCl as an endodontic irrigant.

Uso de ibuprofeno en el tratamiento de pacientes pediátricos con poliuria y disnatremia. Reporte de una serie de casos / Ibuprofen use for the treatment of pediatric patients with polyuria and dysnatremia. A case series report

Los niños con lesiones selares y/o supraselares pueden presentar diabetes insípida central con posterior secreción inadecuada de hormona antidiurética. Nosotros observamos, en algunos casos, aumento de la incidencia de poliuria, natriuresis e hiponatremia, tríada diagnóstica del síndrome cerebral perdedor de sal. Aquí comunicamos la evolución de 7 pacientes con antecedentes de daño agudo del sistema nervioso central y diabetes insípida central seguida por síndrome cerebral perdedor de sal. Como tratamiento aportamos secuencialmente fluidos salinos parenterales, cloruro de sodio oral, desmopresina, mineralocorticoides e incluso tiazidas. Ante la persistencia de poliuria con hiponatremia, agregamos ibuprofeno. Como resultado de este esquema terapéutico secuencial, este grupo redujo significativamente los valores de diuresis diaria de 10 ml/kg/h a 2 ml/kg/h en un tiempo promedio de 5 días, normalizando también las natremias (de 161 mEq/L a 143 mEq/L) en un tiempo promedio de 9 días. En ningún caso observamos efectos adversos asociados al tratamiento.

Children with sellar and/or suprasellar lesions may develop central diabetes insipidus with subsequent inappropriate antidiuretic hormone secretion. An increased incidence of polyuria, natriuresis, and hyponatremia has been reported in some cases, which make up the diagnostic triad of cerebral salt wasting syndrome. Here we report the clinical course of 7 patients with a history of acute central nervous system injury and central diabetes insipidus followed by cerebral salt wasting syndrome. Treatment included the sequential use of parenteral saline solution, oral sodium chloride, desmopressin, mineralocorticoids, and even thiazides. Due to persistent polyuria and hyponatremia, ibuprofen was added. As a result of this sequential therapeutic regimen, daily urine output reduced significantly from 10 mL/ kg/h to 2 mL/kg/h over an average period of 5 days, together with a normalization of natremia (from 161 mEq/L to 143 mEq/L) over an average period of 9 days. No treatment-related adverse effects were observed in any case.

Poliuria post-obstructiva. Análisis fisiopatológico de un caso / Post-obstructive polyuria. Pathophysiological analysis of a case

The relief of the impediment to urinary flow is the treatment of acute kidney failure due to urinary tract obstruction. However, there is a risk of inducing massive polyuria, which can be self-limited or produce severe contraction of the intravascular volume with pre-renal acute kidney failure and alterations in the internal environment. Polyuria, urine output > 3 L/d or > 200 mL/min for more than 2 hours, can have multiple causes, and can be classified as osmotic, aqueous or mixed. Post-obstructive polyuria obeys different pathogenic mechanisms, which overlap and vary during a patient's evolution. Initially, there is a decrease in vasoconstrictor factors and an increase in renal blood flow, which, added to the excess of urea accumulated, will cause intense osmotic diuresis (osmotic polyuria due to urea). Added to these factors are the positive sodium and water balance during acute renal failure, plus the contributions of crystalloid solutions to replace diuresis (ionic osmotic polyuria). Finally, there may be tubular dysfunction and decreased solutes in the renal medullary interstitium, adding resistance to the action of vasopressin. The latter causes a loss of free water (mixed polyuria). We present the case of a patient with post-obstructive polyuria where, by analyzing the clinical symptoms and laboratory alterations, it was possible to interpret the mechanisms of polyuria and administer appropriate treatment for the pathogenic mechanism.

Children with malignancies and septic shock - an attempt to understand the risk factors

Abstract Objectives: To explain the high mortality of septic shock in children with cancer. Methods: A retrospective cohort from 2016 to 2020, of children aged 0 to 18 years, and septic shock. Results: The authors included 139 patients. Acute lymphocytic leukemia was the most frequent diagnosis (16.5%), and Gram-negative bacteria were the most frequent blood culture isolates (22.3%). There were 57 deaths in ICU (41%), 10 in the first 24 hours of shock (early death). A LASSO model with variables: neutropenia (coefficient 0.215), respiratory (0.81), hematological (1.41), and neurological (0.72) dysfunctions, age (-0.002) and solid tumor recurrence (0.34) generated AUC = 0.79 for the early death outcome. Survivors had significant differences in the PRISM-IV score (mean ± SD 10.9 ± 6.2 in the survivors, 14.1 ± 6.5 in the deceased, p = 0.004), and in the mean number of organ dysfunctions (3.2 ± 1.1 in the survivors, 3.8 ± 6.5 in the deceased, p < 0.001). A positive fluid balance in the first 24 hours of sepsis between 2% and 6% of body weight showed a reduction effect on the probability of death in ICU (hazard ratio 0.47, 95% CI 0.24-0.92, p = 0.027). The recurrence of any cancer was a predictor of in-hospital death, regardless of severity. Conclusions: Recurrence of any cancer is an important risk of sepsis-related death. A positive fluid balance between 20 and 60 mL/kg or 2% and 6% of body weight in the first 24 hours after the onset of sepsis is related to lower mortality.

Analysis of clinical characteristics of 294 acute poisoning patients with gastric lavage / 中华急诊医学杂志

Objective:To describe the current situation of gastric lavage operation and put forward measures for improvement by analyzing the clinical characteristics of 294 patients with gastric lavage in Poisoning Treatment Center of The First Affiliated Hospital of Nanjing Medical University.Methods:The clinical data of 294 patients with acute poisoning and gastric lavage from 2019 to 2021 were collected and analyzed retrospectively, and the related parameters (poison type, gastric lavage volume, poisoning to gastric lavage time, etc.) of each year were compared.Results:A total of 653 poisoning patients underwent gastric lavage from 2019 to 2021, with an average age of (44.2 ±20.1) years, and 134 (45.6%) were male. The main causes of gastric lavage were pesticide poisoning (52.72%) and drug poisoning (42.86%). The volume of gastric lavage was less than 10 L for 43.8% of patients and 10-20 L for 32.7% of patients. Patients with gastric lavage within 60 min after ingestion of poison accounted for 45.3%, followed by 25.8% within 61-120 min. The in-hospital mortality rate was 17.7%. The common complications of gastric lavage were: the incidence of gastrointestinal bleeding (55/121, 45.5%), the incidence of aspiration pneumonia (54/140, 38.6%), and the incidences of electrolyte disorder (21% of low potassium, 29% low calcium, and 10.0% low sodium). Compared with the groups in different years, the proportion of gastric lavage in poisoning was 58.85% vs. 46.60% vs. 32.41%, which decreased year by year, with statistical difference ( P <0.05). And there was no difference in the period from ingestion to gastric lavage and gastric lavage fluid volume. There was an increasing trend in poison types between diquat and other insecticides, but there was no statistical difference. Conclusions:From 2019 to 2021, the most common causes of acute gastric lavage were pesticide poisoning and drug poisoning, and the proportion of diquat and other pesticides showed an overall upward trend. A majority of the patients (71.1%) had gastric lavage within 2 h, and 76.5% of the patients had less than 20 L gastric lavage fluid. In the future, we will further control the amount of gastric lavage fluid and pay attention to the gastric lavage operation of new insecticide poisoning.

Clinical observation of subretinal injection of compound electrolyte intraocular irrigation solution in the treatment of diabetic macular edema with hard exudate / 中华眼底病杂志

Objective:To observe the clinical effect of vitrectomy, inner limiting membrane (ILM) peeling, subretinal injection of compound electrolyte intraocular irrigation solution (CEIIS) and conbercept in the treatment of diabetic macular edema (DME) with hard exudate (HE) (DME-HE).Methods:A prospective clinical study. Thirty-three patients with DME-HE diagnosed by examination in Weifang Eye Hospital from June 2020 to February 2022 were included in the study. Among them, there were 15 males (16 eyes) and 18 females(20 eyes), with the mean age of (62.00±6.54) years. All patients underwent the examinations of best corrected visual acuity (BCVA), scanning laser ophthalmoscope, optical coherence tomography (OCT), and multifocal electroretinography (mf-ERG). Snellen visual acuity chart was used for BCVA examination, which was converted into logarithm of the minimum angle of resolution (logMAR) BCVA for statistic analysis. Macular foveal retinal thickness (CMT) and macular volume (MV) were measured by OCT. The 1 ring P1 wave amplitude density was measured by mf-ERG. The patients were randomly divided into group A and group B, with 17 patients (18 eyes) and 16 patients (18 eyes), respectively. There were no significant differences in age, logMAR BCVA, HE area, CMT, MV, and 1 ring P1 wave amplitude density between the two groups ( t=0.403, 0.972, 0.291, 0.023, -0.268, -0.206; P>0.05). Group A was treated with vitrectomy, ILM peeling, and subretinal injection of CEIIS and conbercept (combined therapy). Group B was treated with intravitreal injection of conbercept (IVC). Follow-up was 12 months after treatment. The changes of BCVA, HE area, CMT, MV, 1 ring P1 wave amplitude density were compared between groups and groups after treatment. The times of injection and complications after treatment were observed. Independent sample t test was used for comparison between the two groups. Results:At 12 months after treatment, compared to before treatment, there were significant differences in logMAR BCVA ( F=14.837), HE area ( χ2=94.522), CMT ( χ2=199.212), MV ( χ2=81.914) and 1 ring P1 wave amplitude density ( F=8.933) in group A ( P<0.05); there were significant differences in CMT ( F=5.540) and MV ( F=7.836) in group B ( P<0.05). Compared between the two groups, logMAR BCVA: 1 week and 6 and 12 months after treatment, the difference was statistically significant ( t=2.231, -2.122, -3.196; P<0.05); HE area: except 1 week after treatment, there were statistically significant differences at other times after treatment ( t=-2.422, -3.107, -3.540, -4.119; P<0.05). CMT, MV, 1 ring P1 wave amplitude density: 12 months after treatment, the differences were statistically significant ( t=-2.653,-2.455, 2.204; P<0.05). During the follow-up period, the injection times of group A and group B were (3.06±1.89) and (5.56±2.04), respectively, and the difference was statistically significant ( t=-3.815, P<0.05). Macular hole and vitreous hematoma were found in 1 eye in group A and 1 eye in group B. Conclusion:Vitrectomy, ILM peeling, subretinal injection of CEIIS and conbercept to treat DME-HE can effectively remove HE, alleviate macular edema, improve BCVA, and reduce CMT and MV. Combination therapy can reduce the number of IVC re-treatments.

【Objective】 To explore the effect of intraoperative cell salvage on allogeneic blood transfusion requirements, coagulation function and electrolytes in postpartum hemorrhage patients. 【Methods】 A study on postpartum hemorrhage patients undergoing cesarean section in the Third Affiliated Hospital of Guangxi Medical University form September 2016 to May 2022 was conducted retrospectively. A total of 137 patients were enrolled and divided into experimental group (n=70) and control group (n=67) according to whether intraoperative cell salvage was used during operation. The blood loss, proportion and volume of allogeneic red blood cells (RBCs) and coagulation component transfusion, hemoglobin (Hb) level, coagulation function, electrolyte, the incidence of complications, proportion of ICU admission, ICU stay and in-hospital stay were compared between the two groups. 【Results】 The proportion of patients receiving allogeneic RBCs in the experimental group and in the control group was 31.4% vs 100.0% (P0.05). 【Conclusion】 This study demonstrated that intraoperative cell salvage could reduce the requirement for allogeneic RBCs without compromising coagulation function in postpartum hemorrhage patients undergoing cesarean section, but the changes of calcium need to be concerned after transfusion.

Application status and views of common bowel cleansing regimens in China / 西安交通大学学报(医学版)

The quality of colonoscopy diagnosis and treatment is closely related to bowel cleansing. At present, polyethylene glycol electrolyte powder is the most widely used bowel cleaning regimen at home and abroad, but its intake is large, which reduces the compliance of patients. In recent years, many reports on the application of new bowel cleansing have emerged abroad. In contrast, the application of bowel cleanser in China is still relatively single, which has large room for improvement. At present, we need to solve the problem of developing a new bowel cleanser suitable for Chinese people to improve patient tolerance and bowel cleaning effect.

Efficacy of Compound Polyethylene Glycol Electrolyte Powder Combined With Linaclotide in Bowel Preparation: A Clinical Randomized Controlled Study / 胃肠病学

Background: The traditional bowel preparation compound polyethylene glycol electrolyte powder (PEG) has poor tolerance in some patients due to the need for a large amount of water, which has a limited cleaning effect and affects the visual field of observation. Therefore, it is of clinical significance to find a bowel cleaning method with strong cleaning power, high safety and is acceptable to most of the patients. Aims: To explore the efficacy and safety of PEG combined with linaclotide in bowel preparation. Methods: A total of 414 patients were randomly divided into 3 groups: control group (3 L PEG group), observation group A (3 L PEG+290 μg linaclotide), observation group B (2 L PEG+290 μg linaclotide). The primary outcome was the efficacy of bowel preparation based on the Boston bowel preparation scale (BBPS), the secondary outcomes were withdrawal time, time interval from preparation to colonoscopy, incidence of complications, cecal insertion rate, detection rates of polyps, adenoma, hemorrhoid and other diseases. BBPS score in constipation subgroup was analyzed. Results: The appropriate bowel preparation rate, BBPS score, and detection rates of polyps and hemorrhoid in observation group A were significantly higher than those in control group and observation group B (P0.05). There were no significant differences in cecal insertion rate, incomplete colonoscopy rate, detection rates of adenoma and other diseases, withdrawal time, time interval from preparation to colonoscopy, and incidence of adverse reactions among the three groups (P>0.05). BBPS score in constipation patients in observation group A was significantly higher than that in observation group B and control group (P<0.05). Conclusions: Linaclotide is safe and effective as an adjuvant for bowel preparation. 3 L PEG combined with linaclotide can improve the quality of bowel cleaning.

The effects of high concentration electrolyte on fat emulsion stability in multi-chambered bag parenteral nutrition / 中华临床营养杂志

Objective:To investigate the effect of high concentration electrolyte on fat emulsion stability in multi-chambered bag parenteral nutrition, and to protect clinical drug safety.Methods:Multi-chambered bag parenteral nutrition with the same composition containing high concentration electrolyte were used, except for that water-soluble vitamins, fat-soluble vitamins, sodium glycerophosphate and trace elements were supplemented in the experimental group only. The appearance, pH, osmolality and average particle size were examined at 0, 12, 24, 36, 48, 60, 72, and 168 hours after preparation under room temperature.Results:There was no flocculation or oil-water separation in both groups. The pH value was 5.73 to 5.83 for the experimental group, while that was 5.52 to 5.57 for the control group ( P<0.001). For both groups, the comparison between 0 and 168 hours showed significant differences ( P<0.001). The osmolality was significantly different between the experimental group (1 076-1 117 mOsmol/kg) and the control group (1 072-1 104 mOsmol/kg, P=0.012), but showed no statistical significant difference across examined time points within each group ( P>0.05). The average particle size was 296.1 to 310.9 nm for the experimental group, and 296.6 to 334.9 nm for the control group, showing no statistical significant difference ( P=0.096). The particle size showed no profound changes over time in both groups ( P>0.05). Conclusions:The average particle size of fat emulsion in multi-chambered bag parenteral nutrition were basically stable over 168 hours after preparation under room temperature. The addition of water-soluble vitamins, fat-soluble vitamins, sodium glycerophosphate and trace elements had no significant impact on the stability of fat emulsion.

Rabdomiólisis asociada con hipocalemia en el embarazo y aspectos perinatales. Reporte de un caso clínico / Rhabdomyolysis associated with hypokalemia in pregnancy and perinatal aspects. A case report

Resumen ANTECEDENTES: La rabdomiólisis es un síndrome causado por una lesión en las fibras musculares que produce la liberación de componentes intracelulares (mioglobina, creatinfosfocinasa, aldolasa y lactato deshidrogenasa; electrolitos) hacia el espacio extracelular y la circulación sanguínea, lo que resulta en complicaciones graves (alteraciones cardiovasculares, edema cerebral y muerte). Existen pocos casos reportados de rabdomiólisis durante el embarazo, los informes descritos en la bibliografía se enfocan en infecciones y alteraciones hidroelectrolíticas. CASO CLÍNICO: Paciente de 28 años, primigesta, que inició con alteraciones musculares luego de un cuadro infeccioso, en la semana 18 del embarazo, por lo que se le practicaron estudios para encontrar la causa del desequilibrio hidroelectrolítico (determinación de hipocalemia), con elevación súbita de creatinfosfocinasa. El urocultivo resultó positivo a Escherichia coli. El tratamiento consistió en reposición hidroelectrolítica, con administración de potasio ajustado a los requerimientos de la paciente, antibiótico y aporte nutricional, con alta hospitalaria a los dos días. Continuó en control prenatal y en la semana 32.2 tuvo preeclampsia, por lo que se decidió efectuar cesárea, de la que se obtuvo un recién nacido masculino, de 2395 g, Apgar 9/9, con evolución satisfactoria de la madre y su hijo. CONCLUSIONES: El embarazo es un estado fisiológico que implica mayor susceptibilidad de infecciones o complicaciones asociadas con desequilibrio hidroelectrolítico. Es importante considerar la rabdomiólisis durante el embarazo; el diagnóstico se establece mediante examen clínico y estudios de laboratorio.

Abstract BACKGROUND: Rhabdomyolysis is a syndrome, caused by injury to the muscle fiber, which produces the release of intracellular components such as myoglobin, creatine kinase, aldolase and lactate dehydrogenase, electrolytes, into the extracellular space and blood circulation, which can cause serious complications. such as cardiovascular disorders, cerebral edema and death. There are few reported cases of rhabdomyolysis in pregnancy, the reports described in the literature have been associated with infections and hydroelectrolytic changes. The clinical case is presented due to the importance of the repercussion to the maternal-fetal binomial, since it can result in a serious outcome. CLINICAL CASE: The case of a primiparous pregnant patient is presented, who debuted with clinical symptoms accompanied by muscular alterations after an infection, in week 18 of gestation, for which a study protocol was requested with the finding of hydroelectrolyte imbalance, of the hypokalemia type, with sudden elevation of creatine phosphokinase. A positive urine culture for Escherichia coli was found. Management with hydroelectrolyte replacement was indicated, with potassium replacement adjusted to requirements, antibiotic, and nutritional contribution, with hospital discharge after 2 days. Prenatal control was continued and at week 32.2 she presented preeclampsia, which is why a cesarean section was decided, a male weighing 2395 g, Apgar 9/9, with satisfactory evolution of the binomial was obtained. CONCLUSIONS: Pregnancy is more susceptible to infections or complications associated with hydroelectrolyte imbalances, rhabdomyolysis can occur in pregnancy, and it is important not to rule it out, its diagnosis can be made clinically and through laboratory tests.

Refractory hypokalemia: a case report

Hypokalemia is a common electrolyte disturbance in hospitalized patients, which prompts appropriate identification of hypokalemia symptoms and signs. As many as 20% of hospitalized patients are found to have hypokalemia. Many hypokalemia patients could also have systemic disease.A 55-year-old woman was presented with weakness, nausea, and vomiting for 2 days before admission. Vomit consisted of water; there was no bloodin the vomit. Defecation was normal; consistency and odor of feces were normal. Patient had diabetes and was already on insulin regiment. Insulin was discontinued during hospitalization since blood sugar was close to lower limit. Electrocardiography (ECG)was within normal limit.Symptoms and signs of hypokalemia may not be readily apparent, as seen in this case. Treatment of hypokalemia should intend not to only replenish potassium, but also to identify underlying cause. Causes include gastrointestinal losses, intracellular shift, renal potassium losses, and inadequate intake.

Administración de fluidos a pacientes graves y su relación con la mortalidad / Fluids administration to seriously ill patients and its relationship with mortality

Introducción: La administración de fluidos constituye uno de los pilares de tratamiento en pacientes que ingresan en Unidades de Cuidados Intensivos, en quienes la reanimación inadecuada y la sobrecarga de volumen empeoran el pronóstico. Objetivo: Caracterizar el estado de la administración de fluidos a pacientes ingresados en la Unidad de Cuidados Intensivos del Hospital General Docente Dr. Antonio Luaces Iraola de Ciego de Ávila y su relación con la mortalidad. Métodos: Se realizó un estudio descriptivo analítico y prospectivo de 147 pacientes ingresados en la Unidad de Cuidados Intensivos del Hospital General Docente Dr. Antonio Luaces Iraola de Ciego de Ávila durante el primer semestre de 2020, para lo cual se evaluaron 598 pruebas de fluidos, algunas variables hemodinámicas y el balance de líquidos en las primeras 72 horas del ingreso. Resultados: El promedio de edad fue de 48,3 años, predominaron las mujeres (55,8 %), la puntuación de APACHE II al ingreso resultó ser de 14,2 puntos y fallecieron 22,4 % de los afectados. Para administrar fluidos prevaleció el criterio clínico (57,2%); mientras que la presión venosa central, la frecuencia cardíaca, la presión arterial media y la diuresis fueron similares en vivos y fallecidos. El balance acumulado de fluidos fue significativamente superior en el grupo de pacientes fallecidos (1984,70 mL vs 260mL). Conclusiones: Los cambios en los parámetros vitales después de administrar fluidos no fueron útiles para evaluar la respuesta al volumen. El balance acumulado de fluidos se relacionó de forma significativa con la mortalidad.

Introduction: Fluids administration constitutes one of the treatment pillars in patients admitted to Intensive Care Unit in which the inadequate reanimation and overload of volume worsen the prognosis. Objective: To characterize the state of fluid administration to patients admitted to the Intensive Cares Units of Dr. Antonio Luaces Iraola Teaching General Hospital in Ciego de Ávila and its relationship with mortality. Methods: An analytic and prospective descriptive study of 147 patients admitted to the Intensive Cares Units of Dr. Antonio Luaces Iraola Teaching General Hospital was carried out in Ciego de Ávila during the first semester of 2020, for which 598 tests of fluids, some hemodynamic variables and the balance of liquids were evaluated in the first 72 hours of admission. Results: The average age was 48.3 years, there was a prevalence of women (55.8 %), the punctuation of APACHE II at admission was 14.2 points and 22.4 % of those affected died. To administer fluids the clinical approach prevailed (57.2 %); while the central venous pressure, heart frequency, the mean arterial pressure and diuresis were similar in alive and dead patients. The accumulated balance of fluids was significantly higher in the group of dead patients (1984.70 mL vs 260 mL). Conclusions: The changes in the vital parameters after administering fluids were not useful to evaluate the response to the volume. The accumulated balance of fluids was related to mortality in a significant way.

McKittrick-Wheelock syndrome secondary to rectal adenocarcinoma

Introduction: McKittrick-Wheelock syndrome is a rare condition that arises from a hypersecretory state secondary to large colorectal tumors, mainly villous adenomas, leading to an electrolytic disorder associated with chronic diarrhea that usually persists for years. It is a relatively unknown disease that can lead to severe complications such as acute kidney injury, severe hyponatremia, and hypokalemia. In fact, it causes death in most untreated cases. Surgical removal of the tumor is the most successful treatment, and symptoms tend to disappear after proper management. Case Report: A 62-year-old man with a 2-year history of mucoid diarrhea preceded by abdominal pain presented with acute kidney injury, hyponatremia, and hypokalemia. A digital rectal examination and sigmoidoscopy were performed, and revealed a large laterally-spreading tumor in the rectum. Further investigation showed a rectal tubulovillous adenoma with secondary McKittrick-Wheelock syndrome. An anterior resection of the rectum with a colonic J-pouch and a diverting ileostomy were performed, and the patient improved with the resolution of the renal failure and electrolyte disturbances. The histopathological analysis revealed an invasive rectal adenocarcinoma. Discussion: McKittrick-Wheelock syndrome is a condition with a low incidence that needs early intervention and proper diagnosis. It is of extreme importance that this disease is included in the differential diagnoses for chronic diarrhea associated with an electrolytic disorder. (AU)

Descongestión durante la Insuficiencia Cardíaca Aguda: importancia y monitorización / Monitoring decongestion in acute heart failure

Persistent congestion following an episode of acute heart failure is associated with higher morbidity and mortality. Monitoring diuretic therapy is essential to guide effective decongestion before patient discharge. Unfortunately, there are no markers which can predict on their own, the exact point in which euvolemia is achieved. Cardiothoracic and extra thoracic ultrasound are other tools to consider when evaluating hemodynamic and interstitial components of congestion. However, the question of which and how many parameters must be used for this purpose, is still unanswered.

Clinical efficacy of adaptive biofeedback training combined with oral administration of compound polyethylene glycol 4000-electrolyte powder in the treatment of children with outlet obstruction constipation: a prospective randomized controlled trial / 中国当代儿科杂志

OBJECTIVES@#To study the clinical efficacy, advantages, and disadvantages of adaptive biofeedback training combined with oral administration of compound polyethylene glycol 4000-electrolyte powder in the treatment of children with outlet obstruction constipation (OOC).@*METHODS@#A total of 168 children with OOC were enrolled in this prospective study. All the subjects were randomly divided into a test group and a control group based on the order of visiting time, 84 in each group. The test group was treated with adaptive biofeedback training combined with oral administration of compound polyethylene glycol 4000-electrolyte powder, and the control group was treated with oral administration of compound polyethylene glycol 4000-electrolyte powder alone. Eleven children in the test group and two children in the control group withdrew from the study since they could not finish the whole treatment course. Finally, 73 children in the test group and 82 children in the control group were included in this analysis. As clinical outcomes, the total score of clinical symptoms and overall response rate were compared between the two groups at weeks 4 and 8 of treatment.@*RESULTS@#There was no significant difference in the total score of clinical symptoms between the two groups at beginning of treatment and at week 4 (P>0.05), while the test group had a significantly lower total score of clinical symptoms than the control group at week 8 (P<0.05). At week 4, there was no significant difference in overall response rate between the two groups (P>0.05), while the test group had a significantly higher overall response rate than the control group at week 8 (P<0.05).@*CONCLUSIONS@#Adaptive biofeedback training combined with oral administration of compound polyethylene glycol 4000-electrolyte powder is significantly associated with improvement of clinical outcomes in the treatment of children with OOC.
