Introduction. Diabetes mellitus (DM) is a highly prevalent disease worldwide. It has been associated with an important morbimortality due to its complications and sometimes as a result of adverse events related to treatment. Insulin pump therapy (IPT) is one of the options used to control this disease and reduces one of the most frequent complication associated with treatment: hypoglycemia, which has also a great impact on life quality and clinical status of patients. Materials and Methods. A descriptive and retrospective study was performed including patients treated and followed by the department of endocrinology from a high-complexity university hospital in Cali, Colombia, between 2012 and 2017. Patients were on IPT and continuous glucose monitoring (CGM): MiniMed Paradigm® Veo™ Insulin Pump (Medtronic®) and MiniMed 640G Insulin Pump-Enlite™ Sensor (Medtronic®). Presentation of hypoglycemia and variables associated with its development were evaluated. Results. 51 patients were included. The main indication for IPT initiation was the report of hypoglycemic episodes and inappropriate metabolic control. Initiation of IPT was related with a decrease in glycosylated hemoglobin (HbA1c) and also a decrease in severe hypoglycemic events and hospitalization due to hypoglycemia. The risk factors linked with clinically significant hypoglycemia were male gender, and standard deviation of glucose measures calculated by CGM. A diminished glomerular filtration rate (GFR) (<60 mL/min/1.73 m2) was correlated with higher risk of severe hypoglycemia. Conclusion. IPT with CGM is a useful strategy in the management of patients with DM; it is associated with a reduction of adverse hypoglycemic events and hospitalizations due to hypoglycemia.
Riedel’s thyroiditis is a rare entity consisting of a fibrotic process of the thyroid which can generate gland destruction, infiltration of cervical structures and even airway obstruction. It has been associated with systemic fibrotic disorders, autoimmune diseases, and more recently with spectrum of diseases related to excess of Immunoglobulin G type 4 (IgG4). Two cases of Riedel’s thyroiditis by IgG4, confirmed by immunohistochemistry and was managed surgically with favorable results during the follow-up time, are presented. These case descriptions highlight the diagnostic challenge of this disease, describe the response with surgical management, and make a brief update on the subject.
Introduction. New-onset diabetes after transplantation (NODAT) is associated with immunosuppression. Its complications can negatively influence patients’ quality of life, which is why it is important to study the associated risk factors and expand the possible therapies in this particular group of patients. Materials and methods. Case-control study nested in a retrospective cohort. It included patients who received kidney transplantation at the high complexity University Hospital Fundación Valle del Lili in Cali, Colombia, between 1995 and 2014. Two controls were assigned for each case, depending on the type of donor and the date of the surgery. Information was collected from clinical records and the institutional TRENAL registry. We carried out a descriptive analysis of the selected variables and identified the risk factors with conditional logistic regression. Results. 122 cases were identified to which 224 controls were assigned. The median age was 44 years (IQR: 34–55), and 54% were men. Having >50 years of age at the time of transplantation (OR: 3.18, 95% CI: 1.6−6.3, p = 0.001), body mass index >30 kg/m2 (OR: 3.6, 95% CI: 1.3−9.7, p = 0.010) and being afro-descendant (OR: 2.74, 95% CI: 1.1−6.5, p = 0.023) were identified as risk factors for the development of NODAT. Pretransplant fasting plasma glucose >100 mg/dl (OR: 2.9, 95% CI: 1.4−6.4, p = 0.005) and serum triglycerides >200 mg/dl (OR: 2.5, 95% CI: 1.4−4.4, p = 0.002) were also reported as independent risk factors. Conclusion. We ratify some risk factors for the development of this important disease, which include certain modifiable characteristics. Interventions aimed at changes in lifestyle could be established in a timely manner before transplant surgery.
Tuberculosis (TB) contact investigation facilitates earlier TB diagnosis and initiation of preventive therapy, but little data exist about the quality of its implementation. We conducted a retrospective cohort study to evaluate processes of TB contact investigation for index TB patients diagnosed in Cali, Colombia, in 2017, including dropout at each stage and overall yield. We constructed multivariable models to identify predictors of completing 1) the baseline household visit and 2) a follow-up clinic visit for TB evaluation among referred contacts. Sixty-eight percent (759/1,120) of registered TB patients were eligible for contact investigation; 77% (582/759) received a household visit. Odds of completing a household visit were significantly lower among men (adjusted odds ratio [aOR]: 0.6; 95% CI: 0.4–0.9; P = 0.009) and patients living in Cali’s western zone (aOR: 0.5; 95% CI: 0.3–0.8; P = 0.008). Among 1880 screened contacts, 31% (n = 582) met the criteria for clinic referral, 47% (n = 271) completed a clinic visit, and 85% (231/271) completed testing. After adjusting for clustering by index patient, odds of completing referral were higher among contacts with cough (aOR: 22; 95% CI: 7.1–66; P < 0.001) and contacts living in the western zone (aOR: 4.1; 95% CI: 1.2–15; P = 0.03). The cumulative probability of a symptomatic contact from an eligible household completing TB evaluation was only 28%. The yield of active TB patients among contacts was only 0.3% (5/1880). Only 16% (17/103) of children aged < 5 years were included, and none of the eight persons were living with HIV-initiated preventive therapy. Routine monitoring of process indicators may facilitate quality improvement to close gaps in contact tracing and increase yield.
Introduction: Insulinomas are rare pancreatic neuroendocrine tumors derived from beta cells responsible for insulin secretion. These tumors are typically manifested by hypoglycemia signs and symptoms, which might be non-specific leading to a delay in the diagnosis. The present study describes the experience in the approach of patients with insulinoma at Fundación Valle del Lili, Cali, Colombia.Case Presentation: A retrospective search of patients with the diagnosis of insulinoma within the database of the pathology service was performed between March 2002 and February 2017. Parameters such as the lesion size and localization, the immunohistochemistry findings, the serum levels of glucose, the insulin and C-peptide levels, the presence of metastasis, and the development of diabetes after surgery were evaluated. A total of nine patients with a diagnosis of insulinoma were enrolled in the study. The cohort comprised of seven men and two women, aged 30–50 years. Whipple triad was present in seven patients. The most common symptom was hypoglycemia-related syncope. All patients underwent surgical resection of the tumor with subsequent resolution of the symptoms. Only one patient was diagnosed with diabetes in the postoperative period.Conclusion: In the last 15 years, only nine cases of insulinoma were detected at the Fundación Valle del Lili, which is consistent with the low incidence of the disease. A higher frequency of the disease is noted in men, unlike that in the literature. However, other clinical and pathological features from large studies are in agreement with the current data. Nevertheless, continual experience in the management and identification of these cases is essential as common clinical manifestations may not be observed.
