An unusual manifestation of severe edema in nephrotic syndrome

Keypoints What is known – Ascites is a common finding in nephrotic syndrome. – Adherence to treatment is important to prevent nephrotic syndrome complications. What is added – Transudation of ascitic fluid through the abdominal wall is a rare complication of nephrotic syndrome. – The treatment of transudation of ascitic fluid and skin lesions is challenging and improvement may take several weeks.info:eu-repo/semantics/publishedVersio

A importância de doses maiores de naloxona no tratamento da intoxicação por metadona

As intoxicações com opiáceos em crianças são raras, mas podem ser fatais. Apresentam-se dois casos de intoxicação por metadona, com desfechos diferentes. A primeira criança, de 33 meses de idade, necessitou de ventilação mecânica e naloxona em perfusão contínua, tendo recuperado sem sequelas. No segundo caso, uma criança de três anos, foram usados suportes ventilatório e inotrópico e foi administrada naloxona, mas ocorreu o falecimento algumas horas após o internamento. Nas duas situações um primeiro bólus de naloxona de oito microgramas por kg de peso não reverteu a intoxicação levando a atrasos diagnóstico e terapêutico. Numa criança em coma com miose e depressão respiratória, após medidas de reanimação e estabilização iniciais, deve ser considerada a hipótese de intoxicação com metadona e administrada naloxona (10 mcg/Kg). Na ausência de resposta deve repetir-se naloxona na dose de 400-800 mcg (uma a duas ampolas)

Induced autolysis of engineered yeast residue as a means to simplify downstream processing for valorization: a case study

The objective of this work was to study the efficiency of different autolysis processes, combining different temperatures and pH conditions, when applied to a genetically engineered yeast residue. The determination of the supernatants’ dry weight showed that the autolysis time could be reduced to half, from 4 to 2 h, if the residue pH was increased from 5 to 8 at 50 °C (18.20% for 4 h and 18.70% for 2 h with a higher pH). This result allowed us to select a short autolysis time to proceed with the second part of the experiments. The application of this faster induced autolysis process enabled us to obtain supernatants with higher concentrations of relevant compounds, such as some amino acids and minerals. An increase in leucine (of around 7%), aspartic acid, valine, phenylalanine, isoleucine and serine (approximately 2%) was observed in the autolyzed samples, when compared to the untreated ones. Also, regarding minerals, the autolysis process allowed us to obtain significantly higher amounts of potassium in the treated samples’ supernatants. This work allowed the selection of a fast and low-cost induced autolysis process for synthetic biotechnology-derived spent yeast residue to attain a product rich in high-value compounds, which can be used in commercial applications, for example, as an animal feed additive.info:eu-repo/semantics/publishedVersio

Acute acalculous cholecystitis in children

RESUMO Introdução: A colecistite aguda alitiásica é uma doença rara em Pediatria. Surge geralmente associada a patologias graves, sendo rara na criança saudável. Caso clínico: Os autores apresentam dois casos de colecistite aguda alitiásica, com etiologias distintas, diagnosticados em duas crianças saudáveis. Discussão: Discute-se a fisiopatologia, apresentação clínica e tratamento desta entidade, salientando-se o papel da ecografia como o exame de eleição no seu diagnóstico.ABSTRACT Introduction: Acute acalculous cholecystitis is rare in pediatric age. It usually is associated with severe pathology, and is rare in healthy children. Case report: We describe two cases of acute acalculous cholecystitis, with distinct etiologies, diagnosed in two healthy children. Discussion: We also discuss the pathophysiology, clinical features and management of acute acalculous cholecystitis, enhancing the ultrasound contribution to its diagnosis

Biochemical Basis of CO2-Related Internal Browning Disorders in Pears (Pyrus communis L. cv. Rocha) during Long-Term Storage

This study aimed at understanding the biochemical basis of internal browning disorders (IBDs) in ‘Rocha’ pear. For this purpose, the effects of storage under normal controlled atmosphere (CA) (3 kPa of O2 + 0.5 kPa of CO2) and IBD-inducing CA (1 kPa of O2 + 10 kPa of CO2) on the antioxidant and fermentative metabolisms and polyphenol oxidase (PPO) activity and phenolics concentration were studied. The higher IBD incidence in high CO2-stored fruits was positively correlated with fermentative metabolites and negatively with ascorbate and H2O2 concentrations, and it was linked to PPO activation. These results indicate that both the antioxidant and fermentative metabolisms are involved in the occurrence of IBD in ‘Rocha’ pear. From the integration of the biochemical and enzymatic data, a schematic model illustrating the effects of high CO2 and low O2 in ‘Rocha’ pears during long-term storage was constructed
