Altered interleukin-2 production in schizophrenia: association between clinical state and autoantibody production.

Mitogen-stimulated interleukin-2 (IL-2) production was measured in 122 patients who met Research Diagnostic Criteria for schizophrenia and 98 normal control subjects. The presence of autoantibodies against seven common antigens was also determined. There was no relationship between the presence of circulating autoantibodies and IL-2 production in control subjects. In patients, however, autoantibody-positive, acutely ill patients had significantly lower IL-2 production as compared with other patients and control subjects. Never-medicated patients showed the same trends for decreased IL-2 production in association with autoantibodies. These data suggest that decreased IL-2 production is associated with acute illness in schizophrenic patients who produce autoantibodies, a trait known to be associated with increased vulnerability to autoimmune disease.     

Computer-Assisted Detection of Pulmonary Nodules: Preliminary Observations Using a Prototype System with Multidetector-Row CT Data Sets

The continued revolution in multidetector-row CT (MDCT) scanning increases the quality of lung imaging but at the cost of a greater burden of data for review and interpretation. This article discusses our preliminary experience with prototype software for lung nodule detection and characterization using MDCT data sets. We discuss the potential role of computer-assisted detection (CAD) as applied to the automatic detection of lung nodules. We also review the process of CAD, outline its potential results, and explore how it may fit into existing radiology practice. Finally, we discuss MDCT data-acquisition parameters and how they may affect the performance of CAD.     

Clinical outcomes in pediatric tibial lengthening and deformity correction: a comparison of the Taylor Spatial Frame with the Orthex Hexapod System

PurposeComparison of two hexapod frame systems in paediatric tibial deformity correction; the Taylor Spatial Frame (TSF) and Orthex Hexapod System.MethodsPaediatric patients with congenital and acquired tibial deformities treated with either TSF (between 2014 and 2016) or Orthex (between 2017 and 2019) frames were included in a retrospective comparative study. Outcome measures were healing index, pin infection rate, regenerate quality and density, software residual rate, deformity correction accuracy, strut exchanges and quality of life (QoL).ResultsThe TSF group had 17 patients (18 frames) and the Orthex group had 21 patients (25 frames). The most common indications for tibial deformity correction were fibular hemimelia (14) and septic or traumatic growth arrest (8). The median time in frame was 230 days (TSF) versus 203 days (Orthex) (p= 0.06). The mean lengthening achieved was 54 mm (TSF) and 51 mm (Orthex) (p = 0.41). The healing index was 41 days/cm (TSF) versus 43 days/cm (Orthex) (p = 0.70). Pin site infections occurred more in the TSF cohort (40%) than in the Orthex cohort (18%) (p < 0.001). The regenerate in the Orthex group showed higher density at three months (p = 0.029) and was more homogenous (p = 0.023) at six months after frame application. Strut exchanges were less frequent with the Orthex system (p < 0.0001). QoL measures were similar in both cohorts (p = 0.92).ConclusionsThis is the first study to compare two hexapod designs in paediatric orthopaedics. The Orthex system showed superiority in regenerate quality and a significant reduction in pin site infection rates. Both systems delivered predictable and accurate limb deformity correction.Level of evidenceIII     

Ophthalmoplegia in an adult with chronic inflammatory demyelinating polyradiculoneuropathy

The authors present a 75-year-old patient with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and ophthalmoplegia. The patient had recurrent exacerbations and remissions of her polyneuropathy over the course of one year. Antibodies to ganglioside GM-I were not detected. Ophthalmoplegia in CIDP is uncommon, but is reported to occur in 3-8% of patients. Ophthalmologists should be aware of the association of CIDP and ophthalmoplegia.

Relationship of Eating Behaviors with Age,Anthropometric Measurements,and Body Composition Parameters among Professional Indian Women

One hundred volunteer female college teachers were selected from Jalandhar, Punjab, India. General obesity was found in 56.6%, 76.9%, and 76.2%, abdominal obesity in 56.6%, 57.7%, and 81.0%, of 30- to 39-year-old (Group I), 40- to 49-year-old, (Group II) and 50- to 59-year-old (Group III) participants, respectively. A significantly (p ≤ .05) lower mean value of uncontrolled eating domain was observed in the participants belonging to Group I in comparison to Groups II and III. The cognitive restraint was less in Group III (13.71%), followed by Group II (14.04%) and I (13.71%). The mean values of emotional eating domain revealed not much difference in Group I (12.19%), Group II (12.65%), and Group III (12.00%). Adiposity showed a significant (p ≤ .10, .05) relationship with age and eating behaviors. In conclusion, lesser cognitive dietary restraint and emotional eating were the variables associated with adiposity in the participants.     

In utero presentation of aggressive systemic mastocytosis in a neonate

Mastocytosis is a clinically heterogenous disease characterized by mast cell hyperplasia in skin, bone marrow and/or visceral organs. Cutaneous mastocytosis is more frequently observed in children, whereas indolent systemic mastocytosis is more commonly observed in adults. Aggressive systemic presentation, particularly of the neonate, is exceptionally rare. We present a rare case of congenital aggressive systemic mastocytosis. The patient was a 37‐week‐old male, born by caesarean section owing to hepatosplenomegaly and ascites diagnosed in utero, who exhibited extensive cutaneous and systemic manifestations of mastocytosis at birth. Mutation analysis of c‐KIT identified D816V mutation in exon 17. Although initial bilateral bone marrow aspirates demonstrated no mast‐cell infiltrates or haematological neoplasm, subsequent bone‐marrow biopsies postmortem exhibited multifocal mast‐cell aggregates. Clinical course was complicated by bacteraemia and cardiorespiratory failure, leading to death at 10 weeks.
