OBJECTIVEHypoglycemia is associated with increased mortality in hospitalized patients. We investigated the relationship between spontaneous hypoglycemia versus insulin-associated hypoglycemia and mortality in hospitalized patients.RESEARCH DESIGN AND METHODSData for this retrospective cohort study were obtained from electronic databases of patients admitted between 1 April 2008 and 30 November 2010. Patients with one or more blood glucose values ≤50 mg/dL on point-of-care glucose testing were considered hypoglycemic. Patients treated with insulin were assumed to have insulin-associated hypoglycemia. Age-, sex-, and race-matched patients with all blood glucose values >70 mg/dL were selected as controls. The Charlson comorbidity index (CCI) was used to control for severity of illness.RESULTSThere were four groups: 1) noninsulin-treated hypoglycemia (NTH) (n = 135), 2) insulin-treated hypoglycemia (ITH) (n = 961), 3) noninsulin-treated control (NTC) (n = 1,058), and 4) insulin-treated control (ITC) (n = 736). Mortality was higher in the ITH group compared with the ITC group (20.3 vs. 4.5%, P < 0.0001), with a relatively higher CCI (1.8 vs. 1.5%, P < 0.0001), but much higher in the NTH group compared with the NTC group (34.5 vs. 1.1%, P < 0.0001), with much higher CCI (2.4 vs. 1.1%, P < 0.0001). Mortality was higher in the NTH group compared with the ITH group (P < 0.0001) but lower in the NTC group compared with the ITC group (P < 0.0001). After controlling for age, sex, CCI, and admission to the intensive care unit, insulin treatment was associated with a lower mortality among the hypoglycemic patients; hazard ratio of death in the ITH group relative to the NTH group was 0.34 (95% CI 0.25–0.47, P < 0.0001).CONCLUSIONSInsulin-associated and spontaneous hypoglycemia are associated with increased mortality among hospitalized patients.
IntroductionAdrenal incidentalomas are defined as masses picked up on imaging studies that were done for apparently different reasons. With frequent use of imaging modalities, incidental adrenal masses are commonly encountered in clinical practice. Guidelines are currently available for the diagnosis and management of adrenal incidentalomas, but the appropriateness of initial work-up and subsequent follow-up of incidental adrenal masses in the community hospital setting is unknown.ObjectiveWe studied the appropriateness of initial work-up and follow-up of incidental adrenal masses discovered on abdominal computerized tomography (CT).MethodsIn our retrospective study, we reviewed sequential CT scans of the abdomen performed in the month of January 2010 at a community hospital. Once patients with one or more adrenal masses were identified, outpatient charts for initial biochemical testing and follow-up imaging were obtained either through directly accessing the electronic medical records or through contacting primary care physician's offices. Patient charts were reviewed to assess the data for the next 2 years following the discovery of an adrenal abnormality.ResultsTwenty adrenal masses were incidentally discovered on 723 abdominal CTs performed within the month of January 2010 resulting in an overall incidence of 2.76%. Of the patients with incidentally discovered adrenal masses, appropriate biochemical and follow-up imaging were only performed in patients referred to an endocrinologist (2 of 20 patients). Thirty percent of patients with incidental masses received a repeat CT scan for non-adrenal reasons, and no change in the mass size was noted.ConclusionDespite published guidelines, the initial work-up and follow-up of patients with an incidentally discovered adrenal mass is unsatisfactory. There is a desperate need for education of providers regarding appropriate work-up of incidental adrenal masses.
Proliferating pilomatricoma is a rare, benign tumor of hair matrix origin that rarely occurs in children. We report the case of a 9-year-old girl with a rapidly growing, proliferating pilomatricoma located on the glabella. The lesion was embolized and surgically excised, with histopathological examination of the tissue confirming the diagnosis of proliferating pilomatricoma.
Background
Sjogren's syndrome (SjS) is an autoimmune disease characterized clinically by dry eyes and dry mouth, and histopathologically by lymphocytic infiltrates in the salivary glands. Labial minor salivary gland biopsy (MSGB) is a major diagnostic test for SjS, deemed positive by a focus score of ≥1, meaning that ≥50 lymphocytes were found in 4 mm2 tissue on hematoxylin and eosin (H&E)‐stained slides. The diagnosis can be challenging, and the above diagnostic criteria has low and variable sensitivity.
Methods
We performed a retrospective study on MSGBs done for possible SjS. We compared the percent of MSGBs which met the histologic criteria by H&E stain alone and that with the addition of CD45, CD3, and CD20 immunohistochemical (IHC) staining for these patients. A total of 45 cases with complete data were analyzed.
Results
Thirty‐five of the 45 patients had the diagnosis of Sjogren's syndrome (SjS+) based on ACR criteria. However, based on H&E staining alone, only 22/35 cases (63%) met the histologic criteria. After adding IHC staining with CD45, CD3, and CD20 to MSGBs of SjS + patients, 29/35 (83%) cases met the histological criteria for SjS. All MSGBs from patients without SjS had no significant lymphocyte infiltrate on either H&E or IHC stains.
Conclusions
Immunohistochemical better identifies lymphocytic infiltrates in MSGB and increases diagnostic certainty. Due to high cost, their use should be restricted to cases where there is high clinical suspicion of SjS and negative H&E evaluation alone, or if the diagnosis is uncertain.

Radiation-induced morphea (RIM) is a rare and underrecognized complication of radiation therapy that most commonly occurs in women after treatment for breast cancer. Although not fully understood, RIM is hypothesized to arise from an increase in cytokines that stimulate collagen production and extracellular matrix formation. Most documented cases of RIM occur 1 year after radiation therapy and are localized to areas that were treated for breast cancer. We report on a case of a female patient with stage IB endometrial adenocarcinoma who was treated with 24 Gray of adjuvant brachytherapy. The patient developed a diffuse morpheaform, pruritic eruption only at distant sites from the brachytherapy treatment field. Although treatment for RIM is generally unsatisfactory, our patient experienced improvement in the pruritus and a regression of the lesions while applying topical 0.1% tacrolimus ointment and 0.1% triamcinolone creme. An early diagnosis of RIM can prevent extensive workup, guide treatment, and improve quality of life for patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
