Abstract
The prevalence of primary hyperparathyroidism (PHPT) is increasing as routine laboratory testing for calcium and parathyroid hormone becomes more prevalent due to heightened awareness of the disease. PHPT affects multiple organ systems including the cardiovascular system. This case report highlights a patient with first degree atrio-ventricular block pre-operatively that resolved after resection of her parathyroid adenoma. This case emphasizes the importance of treating asymptomatic hyperparathyroidism to optimize cardiac function.

Abstract
OBJECTIVES Pure erythroid leukemia (PEL) is exceptionally rare in the pediatric setting. Four pediatric PEL cases with t(1;16)(p31;q24) NFIA-CBFA2T3 were reported previously. We present a case of an infant with PEL presenting with erythroblastic sarcoma and harboring a novel t(1;8)(p31.3;q21.3) NFIA-RUNX1T1 fusion detected by RNA sequencing and conventional karyotype. METHODS Bone marrow (BM) and abdominal mass biopsies from the patient were evaluated with extensive immunohistochemical, flow cytometric, cytogenetic, and molecular studies. RESULTS The patient was a female infant who presented between 2 and 5 months of age with cytopenias and an enlarging abdominal mass. Blasts in the BM and abdominal mass expressed CD71 and CD117 with focal expression of CD43, E-cadherin, epithelial membrane antigen, and hemoglobin A. They were negative for additional myeloid, lymphoid, and nonhematolymphoid markers. These findings were most consistent with PEL and erythroblastic sarcoma. RNA sequencing revealed the novel NFIA-RUNX1T1 fusion. CONCLUSIONS Along with the previously reported PELs with NFIA-CBFA2T3 fusions, we describe a subset of PELs that occur in children, that frequently display extramedullary disease, and that harbor rearrangements of NFIA with core binding factor genes. We hypothesize that, together, these cases represent a rare but distinct clinicopathologic group of pediatric PELs with recurrent genetic abnormality.

Abstract
Background Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids is a clinically and radiographically distinct inflammatory syndrome affecting multiple structures of the brain, including the cerebellum, brainstem, and spinal cord. The clinical presentation can be variable, including ataxia, nystagmus, dysarthria, dysphagia, and other subacute brainstem, cranial nerve, or cerebellar symptoms. These symptoms can be subacute to chronic, episodic, and progressive, making the diagnosis challenging. The hallmark radiographic magnetic resonance imaging findings are gadolinium-enhancing punctate lesions predominantly “peppering” the pons in a perivascular pattern. Case presentation Here, we describe a case and literature review of a 74-year-old Caucasian male who presented with subacute symptoms of ataxia, diplopia, and generalized fatigue. Physical examination was notable for horizontal nystagmus and wide-based gait. Magnetic resonance imaging revealed angiocentric enhancement predominantly in the brainstem and cerebellum, with involvement of the basal ganglia, thalami, and supratentorial white matter. Meanwhile, a screening computed tomography scan demonstrated a right upper lobe mass with biopsy proving primary lung cancer. Biopsy of one of the brain lesions showed perivascular infiltrate primarily composed of CD3+ T cells, scattered CD20+ B cells, and no signs of malignancy. The patient was started on high-dose glucocorticoids followed by a maintenance regimen with rapid improvement clinically and radiographically. Given extensive work-up was negative, these clinical and radiographic findings were consistent with chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids. Conclusions This case illustrates the difficulty of diagnosing chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids, given its variable presentation, lack of specific laboratory findings, and poorly understood pathogenesis. We demonstrate a case that responded well to oral corticosteroid burst followed by a taper to the lowest corticosteroid dose clinically possible. Failure to recognize this syndrome could result in permanent central nervous system morbidity. Therefore, earlier recognition is crucial for this treatable condition.

Abstract
Neonatal intestinal masses with spindle cell morphology have broad differential diagnoses and require a multidisciplinary approach to make the final diagnosis. Spindle cell masses with heterotopic cartilage in the gastrointestinal tract are very rare, and, to our knowledge, have not previously been reported in the neonate. Here we present a case of intestinal primitive spindle cell neoplasm with extensive heterotopic cartilage that manifested initially as acute abdomen in a 6-day-old term infant. Plain radiography demonstrated pneumoperitoneum, prompting diagnostic laparotomy that identified a perforated mass involving the midileum. Histologic and immunohistochemical examination demonstrated an infiltrative spindle cell tumor most compatible with infantile fibrosarcoma (IFS) by a process of exclusion, with nodules of mature heterotopic cartilage. Additional staging studies did not reveal any evidence of residual or metastatic disease. Recognition of this rare variant of IFS will aid in differentiation from other neonatal intestinal mesenchymal tumors.

Abstract
Infantile hemangiomas are the most common benign neoplasm of infancy, with most occurring in the head and neck region. Predisposing factors include prematurity, low birth weight, multiple gestations, advanced maternal age, and chorionic villous sampling. In addition, white women, particularly those with a family history, are also at a higher risk. However, pulmonary infantile hemangiomas are exceedingly rare, with only a few case reports in the literature. Infantile hemangiomas should be considered in the differential diagnosis of a pulmonary mass in the early pediatric population. We present a case of pulmonary infantile hemangioma in a premature male infant successfully managed by surgical excision, with an emphasis on the pathogenesis and histologic features.

Abstract
Thyroid-like follicular carcinoma of the kidney (TLFCK) is a rare histological variant of renal cell carcinoma not currently included in the World Health Organization classification of renal tumors. Only 24 previous cases of TLFCK have been reported to date. We report a case of TLFCK in a 19-year-old woman with history of pediatric acute lymphoblastic leukemia. This patient is the youngest with TLFCK to be reported to date and the first with history of lymphoblastic leukemia. The development of TLFCK in a young patient with history of lymphoblastic leukemia is interesting and suggests that genes involved in leukemogenesis may also be important for TLFCK pathogenesis. Recognition of TLFCK is important to distinguish it from other conditions that show thyroid-like features, as a misdiagnosis can result in adverse patient care.

Abstract
Solitary fibrous tumors (SFTs) are unusual spindle cell neoplasms initially described in the pleura but have since been discovered in many extrapleural locations. SFT of the kidney is extremely rare, the majority occurring in middle-aged adults. To date, only two pediatric cases of renal SFT have been reported. We report a case of large SFT in the kidney of a 3-year-old boy that was clinically and radiologically thought to be a nephroblastoma. This case is the first pediatric renal SFT to be reported with detailed histopathologic and cytogenetic analyses. SFT should be included in the differential diagnosis of pediatric renal tumors.

Abstract
BACKGROUND Choroid plexus tumors (CPT) are rare, and predominate in early childhood. An association with the Li-Fraumeni syndrome (LFS) has been reported, but the biological and clinical implications of this association remain poorly defined. We have investigated the clinical features and overall survival of all CPT patients treated at Children's Hospital Los Angeles (CHLA) over a 20-year period, with particular attention to the association of CPT with LFS. METHODS A retrospective evaluation of the course of therapy and clinical outcome was undertaken on the 42 patients diagnosed with and treated for CPT at CHLA from January 1991 to December 2010. Any association with multiple primary tumors and family histories consistent with LFS was investigated in all patients. RESULTS Six of the 42 patients (16.7%), demonstrated either phenotypic and/or genotypic characteristics consistent with LFS, with either a distinct family history of cancer, a synchronous diagnosis of a different type of cancer, or the subsequent development of metachronous cancers. Of 11 patients with choroid plexus carcinoma tested for TP53 germline mutations, four (36.4%) were positive. A single patient with a choroid plexus papilloma had phenotypic characteristics of LFS but tested negative for TP53. CONCLUSIONS Children with CPC appear to have a high frequency of TP53 germline mutations in association with LFS. This raises the question whether all children with CPC should be tested for TP53 germline mutations in order to institute screening to enhance early detection and treatment of subsequent cancers.

Abstract
PURPOSE Choroid plexus carcinomas are pediatric tumors with poor survival rates and a strong, but poorly understood, association with Li-Fraumeni syndrome (LFS). Currently, with lack of biologic predictors, most children are treated with aggressive chemoradiation protocols. PATIENTS AND METHODS We established a multi-institutional tissue and clinical database, which enabled the analysis of specific alterations of the TP53 tumor suppressor and its modifiers in choroid plexus tumors (CPTs). We conducted high-resolution copy-number analysis to correlate these genetic parameters with family history and outcome. Results We studied 64 patients with CPTs. All individuals with germline TP53 mutations fulfilled LFS criteria, whereas all patients not meeting these criteria harbored wild-type TP53 (P < .001). TP53 mutations were found in 50% of choroid plexus carcinomas (CPCs). Additionally, two sequence variants known to confer TP53 dysfunction, TP53 codon72 and MDM2 SNP309, coexisted in the majority of TP53 wild-type CPCs (92%) and not in TP53 mutated CPC (P = .04), which suggests a complementary mechanism of TP53 dysfunction in the absence of a TP53 mutation. High-resolution single nucleotide polymorphism (SNP) array analysis revealed extremely high total structural variation (TSV) in TP53-mutated CPC tumor genomes compared with TP53 wild-type tumors and choroid plexus papillomas (CPPs; P = .006 and .004, respectively). Moreover, high TSV was associated with significant risk of progression (P < .001). Five-year survival rates for patients with TP53-immunopositive and -immunonegative CPCs were 0% and 82 (+/- 9%), respectively (P < .001). Furthermore, 14 of 16 patients with TP53 wild-type CPCs are alive without having received radiation therapy. CONCLUSION Patients with CPC who have low tumor TSV and absence of TP53 dysfunction have a favorable prognosis and can be successfully treated without radiation therapy.

Abstract
The steady-state effect of 2,5,2′,5′-tetrachlorobiphenyl (TCBP) on the green alga

in the control). Photosynthetic efficiency, or the slope of the photosynthesis-irradiance curve, was also significantly higher. There was little difference in the cell chlorophyll

content, and therefore the difference in these photosynthetic characteristics was the same even when they were expressed on a per-chlorophyll
a
basis. Cell C content was higher in TCBP-containing cells than in TCBP-free cells, but approximately 36% of the C fixed by cells with TCBP was not incorporated as cell C. The maximum P uptake rate was also enhanced by TCBP, but the half-saturation concentration appeared to be unaffected.

Abstract
Although not uncommon after penetrating vascular trauma, arterial pseudoaneurysms rarely develop following blunt trauma. A patient is described in whom indirect trauma led to pseudoaneurysm of the profunda femoris artery, and persistent bleeding required surgical intervention. In this case, the coexistence of significant aortic valvular regurgitation suggests that wide pulse pressure may predispose to this arterial complication.

Abstract
Forty-six episodes of bacteremia were observed during a three-year period at a small, non-urban community hospital. The incidence of bacteremia was 4.3 episodes per 1,000 admissions; this rate is similar to the incidence of bacteremia in large, urban community hospitals but lower than the incidence of bacteremia in municipal or academic hospitals. Eleven percent of bacteremias were hospital acquired, an incidence of 0.5 hospital acquired bacteremias per 1,000 admissions. The low incidence of hospital acquired bacteremia was a reflection of the low incidence of nosocomial, aerobic, gram-negative bacteremia (0.1 per 1,000 admissions). Thirteen percent of bacteremic patients died. The mortality in patients with community acquired bacteremia (10%) was lower than that reported from larger, urban hospitals; the mortality in patients with hospital acquired bacteremia (40%) was similar to that reported from larger, urban hospitals. The lower rates of bacteremia and associated mortality that were observed appear to be due to the lesser severity of underlying diseases in these patients.
