ABSTRACT
Malignant Pleural Mesothelioma (MPM) is a rare pleural malignancy, with a vague presentation complicated by a decades-long latency period between environmental exposure and clinical manifestations. Spontaneous hydro-pneumothorax is a rare presentation of MPM, most often requiring invasive tissue biopsy to confirm the etiologic diagnosis. We present the case of 79-year-old male smoker with no documented history of asbestos exposure, who was found to have MPM after presenting with dyspnea and subsequently found to have recurrent hydro-pneumothorax. On Literature review of the limited documented cases of MPM with hydro-pneumothorax, we found an exclusively male population with a significant smoking history, a marked right sided pathology predominance, and a generally poor prognosis. While this corresponds with the examined case, and suggests that the presence of hydro-pneumothorax implies a high-grade tumor and significant tissue invasion, and therefore poor prognosis similar to that of stage 4 disease, it differs from more generalized case reviews of MPM, most importantly in their anatomical descriptions, prognostic indicators, and epidemiologic tendencies.
ABSTRACT
OBJECTIVE: To determine the prevalence of antibodies associated with celiac disease and biopsy-proven celiac disease in children with autoimmune thyroid disease. STUDY DESIGN: A total of 302 patients with positive anti-thyroid antibodies were prospectively studied. Total immunoglobulin A (IgA) and tissue transglutaminase-IgA (tTG-IgA) levels were obtained. Those with a positive tTG-IgA titer were offered biopsy for definitive diagnosis of celiac disease. RESULTS: A total of 4.6% of subjects with autoimmune thyroid disease had positive tTG-IgA titers. The prevalence of biopsy-confirmed celiac disease was 2.3%. Our population was enriched with patients with type 1 diabetes mellitus (4.3%) and Down syndrome (3.4%). Excluding individuals with these co-morbidities, the prevalence of celiac disease in autoimmune thyroid disease is 1.3%, similar to that of the general population. The positive predictive value of biopsy-proven celiac disease in patients with autoimmune thyroid disease and positive tTG-IgA titer was 54%. CONCLUSION: The increase in prevalence of celiac disease in autoimmune thyroid disease in our study was largely caused by enrichment with co-morbidities. Without comorbidities or symptoms, screening for celiac disease may not be justified in this population. The specificity of tTG-IgA titer for the diagnosis of celiac disease was decreased in patients with autoimmune thyroid disease compared with the general population.

Unexplained hypoglycemia in a pediatric diabetic patient can perplex even the savviest health care providers and lead to an extensive medical workup. We present here the cases of 2 children with type 1 diabetes mellitus treated with insulin pumps who were hospitalized for episodes of hypoglycemia. Review of their insulin pumps revealed normal basal and bolus insulin delivery. However, subsequent review of the priming history in the pump revealed that both children were receiving additional insulin under the manual-prime function, which is not included in the daily totals and, therefore, was initially unnoticed. Ultimately, both children confessed to surreptitiously using this priming function to self-administer extra insulin. It is important that health care professionals who are caring for diabetic patients be aware of this possibility.
