Abstract Introduction Glycemic control is important to avoid diabetes complications in individuals with cancer. There is no evidence for HbA1c and fructosamine as reliable biomarkers in these conditions. There are particularities in caring for patients with diabetes and cancer that can alter these biomarkers. Objective The aim of this study was to evaluate HbA1c and fructosamine as glycemic biomarkers in people with type 2 diabetes and cancer, undergoing clinical or surgical oncological treatment. Methods The authors conducted a single-center, retrospective analysis with people who have cancer and diabetes. Comparison of glycemic biomarkers (HbA1c, fructosamine, and Self-Monitoring of Blood Glucose [SMBG]) was performed including evaluation in individuals undergoing chemotherapy, using glucocorticoids, with anemia, hypoproteinemia or with reduced estimated Glomerular Filtration Rate (eGFR). Results There was a strong positive correlation between fructosamine and HbA1c (n = 318, r= 0.66, p < 0.001) in people with diabetes and cancer even in those under chemotherapy (n = 101, r= 0.61, p < 0.001) or using glucocorticoids (n = 96, r= 0.67, p<0.001). There was a strong correlation between HbA1c and fructosamine in subjects with anemia (n = 111, r= 0.66, p < 0.001), hypoproteinemia (n = 54, r= 0.67, p < 0.001), or with eGFR ≥ 60 mL/min/1.73 m2 (n = 189, r= 0.70, p < 0.001), and moderate correlation with hypoalbuminemia (n = 21, r= 0.54, p = 0.001) and with reduced eGFR (n = 67, r= 0.57, p < 0.001). The correlations between fructosamine and HbA1c with SMBG were moderate (n = 164, r= 0.49, p < 0.001; n = 111, r= 0.55, p < 0.001, respectively), strong in subjects undergoing chemotherapy, with hypoalbuminemia or hypoproteinemia, and at least moderate, if eGFR < 60 mL/min/1.73 m2 or with anemia. Conclusions Fructosamine and HbA1c can be used as glycemic biomarkers in people with diabetes and cancer, even in those with anemia, hypoproteinemia, or undergoing chemotherapy.

ABSTRACT Objective: We assessed metrics related to inpatient glycemic control using InsulinAPP, an application available for free in Brazil, on the hospitalist-managed ward of our hospital. Subjects and methods: We performed a retrospective study of patients with type 2 diabetes (T2D) admitted from November 2018 to October 2019. InsulinAPP recommends NPH and regular insulins three times a day, in bolus-correction or basal-bolus schemes. Parameters that included BG within range of 70-180 mg/dL, insulin treatment regimen and frequency of hypoglycemia were evaluated. Results: A total of 147 T2D individuals (23% medicine and 77% surgery) were included (mean age 62.3 ± 12.7 years, HbA1c: 8.3 ± 3.0%). The initial insulin regimen was 50% bolus-correction, 47% basal-bolus and 3% with sliding scale insulin. During hospitalization, 71% patients required a bolus-basal regimen. In the first 10 days of the protocol, 71% BG measurements were between 70-180 mg/dL and 26% patients experienced one or more episodes of hypoglycemia < 70 mg/dL, and 5% with BG < 54 mg/dL. Conclusion: The results of this retrospective study indicate the InsulinAPP application using human insulin formulations was effective and safe for the management of hyperglycemia on a hospitalist-managed ward, with more than 70% BG measurements within the therapeutic range and a low rate of hypoglycemia.

ABSTRACT Objective To analyze interstitial glucose behavior during glucocorticoid use in non-diabetic patients receiving chemotherapy for hematologic malignancies. Methods Prospective pilot study carried out to assess interstitial glucose levels in 15 non-diabetic individuals with hematologic malignancies who received glucocorticoids in combination with chemotherapy. The FreeStyle Libre flash monitoring system (Abbott Diabetes Care) was used for up to 14 days to measure interstitial glucose. Results Median age and body mass index were 53 (42-61) years and 25 (23-28) kg/m2 respectively. Interstitial glucose levels >180mg/dL lasting at least one hour were detected in 60% of participants. Interstitial glucose profile parameters (median and peak interstitial glucose levels and percentage of time during which interstitial glucose levels were >180mg/dL) were significantly (p<0.01) higher during glucocorticoid use (115mg/dL, 218mg/dL and 10% respectively) than after glucocorticoid discontinuation (97mg/dL, 137mg/dL and 0% respectively). Mean interstitial glucose levels increased in the afternoon and at night during glucocorticoid use. Conclusion This pilot study was the first to evaluate interstitial glucose levels in non-diabetic individuals using glucocorticoids in treatment of hematologic cancer. Glucocorticoid use during chemotherapy significantly increases interstitial glucose levels in these patients.

SUMMARY Collision tumors are rare and may comprise components with different behavior, treatments, and prognosis. We report an unprecedented case of aggressive thyroid collision tumor containing widely invasive oncocytic carcinoma (OC), classical and hobnail (HPTC) variants of papillary carcinoma, and poorly differentiated carcinoma (PDTC). The patient underwent total thyroidectomy, radioactive iodine therapy, and within months progressed with local recurrence, and pulmonary metastases requiring neck dissection, external radiotherapy and systemic treatment with sorafenib. The rapid progression, dedifferentiated metastatic lesions, and failure to treatments resulted in the patient´s death. The great variety of histological types and the evolution of this case were a challenge for the management of metastatic disease. Widely invasive OC, HPTC and PDTC are considered to have a worse prognosis. HPTC has never been reported as a component of a collision tumor. HPTC and PDTC should call attention to a possible higher-grade transformation.

A crise celíaca é uma manifestação rara e grave da doença celíaca. Relatamos um caso de uma paciente de 30 anos de idade, com antecedente de diabetes melito tipo 1 e história de um mês de diarreia aquosa aguda, associada a náuseas, vômitos, dor abdominal e perda de peso de 9 kg. A hipótese diagnóstica de crise celíaca foi realizada, baseada no quadro de diarreia profusa, desidratação e distúrbios hidroeletrolíticos e ácido-básicos que melhorou após a introdução de dieta enteral sem glúten

Celiac crisis, an acute severe onset of celiac disease, is a rare and life-threatening manifestation. We report a 30-year-old woman with type 1 diabetes mellitus who arrived at our service with one-month history of severe acute watery diarrhea associated with nausea, vomiting, abdominal pain, and weight loss of 9 kg. The diagnostic hypothesis of celiac crisis was reached based on profuse diarrhea leading to dehydration, severe metabolic and electrolyte abnormalities, and subsequent improvement after introduction of a gluten-free diet.

Foram relatados dois casos de peritonite bacteriana espontânea (PBE) por Listeria monocytogenes em pacientes com cirrose. Em um dos casos isolamos também o agente no líquido pleural. A PBE é uma complicação comum e grave de pacientes com ascite por cirrose e a cultura do líquido ascítico é de grande importância para o diagnóstico e para o tratamento mais adequado. Embora uma cefalosporina de terceira geração seja geralmente utilizada para o tratamento empírico da PBE, ela não oferece cobertura adequada contra a Listeria spp. Nesses casos, recomenda-se o uso de ampicilina (com ou sem sulbactam) ou sulfametoxazol-trimetoprim. Para a profilaxia secundária indica-se o uso deste último, ao invés da norfloxacina. Em resumo, a infecção por Listeria monocytogenes é uma causa rara de PBE e o tratamento específico deve ser administrado.

Two cases of spontaneous bacterial peritonitis (SBP) caused by Listeria monocytogenes in cirrhotic patients are reported. In one of the cases, the microorganism was isolated from pleural effusion and ascites. SBP is a serious and common complication of patients with ascites caused by hepatic cirrhosis and the culture of the ascitic fluid is an important tool for the diagnosis and for the more appropriate treatment. Although a third generation cephalosporin has usually been employed for empiric treatment of SBP, it does not provide adequate coverage against Listeria spp. In such cases the use of ampicillin (with or without sulbactam) or sulfamethoxazole-trimethoprim is recommended. The last one is used for secondary prophylaxis, instead of norfloxacin. To summarize, Listeria monocytogenes infection is a rare cause of SBP, whose treatment should be specific for the bacteria.

Papular-purpuric "gloves and socks" syndrome (PPGSS) is a novel, rare, self-limiting dermatosis caused by human parvovirus B19. It consists of pruritic edema and erythema of the hands and feet in a gloves-and-socks distribution, and it is associated with oral lesions and fever. We present a case of PPGSS in a 22-year-old Brazilian woman. Clinical and laboratory evaluation, including serological tests, PCR and gene sequencing, confirmed the presence of human parvovirus B19.

OBJETIVOS: Analisar a morbidade por doenças respiratórias, medida pelas internações hospitalares, no município de São Paulo de 1995 a 2000, descrevendo o comportamento das internações por doenças respiratórias totais, pneumonias, asma e doença pulmonar obstrutiva crônica (DPOC), conforme sexo e idade, e identificar suas tendências. MÉTODOS: As informações referentes às internações hospitalares, para todas as idades e causas, foram obtidas através das Autorizações de Internações Hospitalares do SUS - Ministério da Saúde (DATASUS). Foi realizada análise descritiva com gráficos e tabelas. RESULTADOS: Houve decréscimo no número absoluto e na taxa de internações por doenças respiratórias totais em todas as idades, mas de maneira não uniforme em todo o período. Para DPOC, observou-se tendência de aumento importante, principalmente entre os idosos. A população masculina foi mais afetada do que a feminina em todos os anos, por quaisquer causas estudadas, com exceção da asma. As pneumonias representaram a causa mais importante de hospitalizações, com 47% das internações. As internações, principalmente das pneumonias, apresentaram padrão sazonal marcante. CONCLUSÃO: Neste período de seis anos, nossas análises revelaram a participação importante das pneumonias como causa de internação. Porém, estas doenças vêm apresentando uma tendência decrescente, ao contrário de doenças crônicas como a DPOC e a asma. Estes resultados indicam uma ligeira mudança no perfil destas doenças no nosso meio, o que traz conseqüências imediatas para o planejamento de serviços e para a formulação de políticas de saúde.

OBJECTIVES: To analyze trends in morbidity due to respiratory diseases, using hospital admissions in the city of São Paulo from 1995 to 2000. To describe the evolution of the morbidity for respiratory diseases in general and for pneumonias, for asthma and for chronic obstructive pulmonary disease (COPD), by sex and age. METHODS: The information on hospital admissions for all ages and causes were obtained from the Hospitalizations Information System of the Brazilian Ministry of Health (DATASUS). Descriptive analysis of patterns and trends were performed. RESULTS: There was a decreasing trend in the absolute number and the rate of hospitalization for respiratory illnesses for all ages but not uniformly during the period. For COPD, an increasing trend was observed, especially for the elderly. The male population was more affected than the female in all years, for any studied causes with the exception of asthma. The pneumonias represented the most important cause of hospitalizations, with 47% of all respiratory admissions. Important seasonal pattern was observed for pneumonia admissions. CONCLUSION: In this period of 6 years, our analyses had disclosed an important participation of pneumonias as a cause for respiratory admissions. However, these diseases presented a decreasing trend, in contrast to chronic illnesses such as COPD and asthma. These results point out to a changing pattern in the respiratory morbidity with direct consequences for public health policy making.
