Predictors of glycemic control after decline of insulin therapy by patients with type 2 diabetes.

Aim: Decline of insulin therapy by patients is common but poorly investigated. We conducted this study to determine patient and treatment characteristics predictive of glycemic control after declining clinician recommendation to initiate insulin therapy.

Methods: We retrospectively studied adults with type 2 diabetes mellitus treated at two academic medical centers between 1993 and 2014 who declined their healthcare provider recommendation to initiate insulin.

Primary breast lymphoma with sudden death.

Primary breast lymphoma is a rare form of extranodal lymphoma. B cells constitute the most common type involving the breast. T cells represents only 3%.

Postmortem findings in eight cases of influenza A/H1N1.

In March and early April 2009, cases of a new swine-origin influenza A (H1N1) virus were diagnosed in Mexico and the United States. Influenza virus presents as a respiratory infection with high morbidity and mortality. We describe the postmortem findings of eight confirmed cases of influenza A/H1N1 in a medical examiner setting.

Cytologic features of subependymal giant cell astrocytom: a review of 7 cases.

Objective: To describe the cytologic features of subependymal giant cell astrocytoma (SEGA) on smears and analyze cytomorphologic parameters that may help in reaching the diagnosis of SEGA.

Study Design: Cytologic smears of 7 cases of SEGA were reviewed and graded semi-quantitatively for 11 cytologic features: clustering, cytoplasmic fibrillary processes (fibrillarity), cellularity, small prominent nudcleoli, binucleation or multinucleation, "strap cells", spindle-shaped cells, mitoses, intranuclear inclusions, nuclear atypia and perivascular palisading/pseudorosettes. Corresponding histologic sections were also reviewed.

Ovarian cancers overexpress the antimicrobial protein hCAP-18 and its derivative LL-37 increases ovarian cancer cell proliferation and invasion.

The role of the pro-inflammatory peptide, LL-37, and its pro-form, human cationic antimicrobial protein 18 (hCAP-18), in cancer development and progression is poorly understood. In damaged and inflamed tissue, LL-37 functions as a chemoattractant, mitogen and pro-angiogenic factor suggesting that the peptide may potentiate tumor progression. The aim of this study was to characterize the distribution of hCAP-18/LL-37 in normal and cancerous ovarian tissue and to examine the effects of LL-37 on ovarian cancer cells.

Postoperative cranial fasciitis. Report of two cases and review of the literature.

The authors report two cases of cranial fasciitis occurring at prior craniotomy sites. They review the presentation and pathological features associated with cranial fasciitis and describe two unusual cases and their treatment. The first case is that of a 16-year-old girl who underwent suboccipital craniectomy for resection of medulloblastoma and 14 months later was found to have a 4-cm nontender mass at the incision site, with evidence of skull erosion on neuroimaging.

Erythropoietin, a hypoxia-regulated factor, elicits a pro-angiogenic program in human mesenchymal stem cells.

Objective: The ability of erythropoietin (EPO) to elicit a pro-angiogenic effect on human mesenchymal stem cells (hMSC) was tested. hMSC are currently under study as therapeutic delivery agents that target tumor vessels. Hypoxia favors the differentiation of hMSC towards a pro-angiogenic program.

Medulloepithelioma: Two unusual locations.

Reported herein are two cases of medulloepithelioma (ME) occurring in very unusual locations. Case 1 involved a 44-year-old man who presented with leg pain and urinary incontinence. Spine magnetic resonance imaging (MRI) showed an enhancing epidural and intradural lumbosacral mass.

De novo paracentric inversion (X)(q26q28) with features mimicking Prader-Willi syndrome.

Different genetic and non-genetic disorders, including several chromosomal abnormalities, may mimic Prader-Willi syndrome (PWS). We report on an 11-year-old girl with features reminiscent of PWS due to an unreported de novo paracentric inversion Xq26q28. Microdeletion 15q11-q13 and maternal uniparental disomy 15 were ruled out.

Epstein-Barr virus-associated gastric carcinoma in Cali, Colombia.

To estimate the incidence of Epstein-Barr virus-associated gastric carcinoma (EBV-GC) in Colombia and to clarify its clinicopathological features, we examined 178 consecutive gastric carcinoma cases, diagnosed during the period from 1996 to 1998, at Hospital Universitario del Valle in Cali, Colombia. The mean age of the cases was 60 years in males and 58 years in females. Using in situ hybridization assay of EBV-encoded small RNA-1 in paraffin-embedded tissue samples, we identified 23 cases of EBV-GC (13%).

EXIT procedure: a case report.

The EXIT (Ex-Utero Intrapartum Treatment) procedure is an extremely valuable tool in providing time to secure the airway in infants with large fetal neck masses and abnormalities of the upper airway which impede resuscitation. The fetus is partially delivered while maintaining utero-placental-fetal circulation. We report the use of this technique in a case of huge cystic hygromas of the neck and chest due to a nuchal bleb-lethal dysplasia.
