Retroperitoneal fibrosis: evolving concepts

Retroperitoneal fibrosis (RPF) is a rare fibro-inflammatory condition that is idiopathic in most cases, but may be secondary to various causes. Although the cause and pathogenesis of the idiopathic form are unknown, immunogenetic factors and immunopathologic/autoimmune mechanisms are probably involved. Idiopathic RPF usually develops around the abdominal aorta and iliac arteries but in some cases may also involve the thoracic aorta and the origin of its major branches, with a pattern similar to that of other forms of large-vessel vasculitis. In addition, the disease is frequently associated with autoimmune conditions affecting other organs. Glucocorticoids alone or in combination with immunosuppressive agents are usually effective treatment options, but the disease frequently has a chronic relapsing course.     

Predictors of successful rehabilitation in geriatric patients: subgroup analysis of patients with cognitive impairment

BACKGROUND AND AIMS: Understanding which patients benefit from rehabilitation programs may be useful in balancing resources and needs. The aim of this study was to evaluate whether cognitive and nutritional status are associated with functional improvement after rehabilitation in old persons. METHODS: 2650 patients (aged > or =60 years) consecutively admitted to a geriatric rehabilitation unit in Italy between August 2001 and December 2005, were included. Functional status was evaluated with the Tinetti scale, cognitive status with the Mini-Mental State Examination (MMSE), and nutritional status with the Mini-Nutritional Assessment Short Form (MNA-SF). To identify predictors of functional recovery, multiple logistic regression models were run, with improvement on the Tinetti scale score as dependent variable. RESULTS: Eighty per cent of old persons functionally improved after rehabilitation, ranges being 84% of those with MMSE> or =24 to 58% of those with MMSE<10. Persons with both good cognition and good nutritional status were most likely to improve [odds ratio (OR)=2.5; 95% confidence interval (95% CI)=1.9-3.2]. Stratifying the sample according to cognitive status, we found that in patients with MMSE> or =18 better nutritional status emerged as a factor associated with functional improvement, whereas in patients with severe cognitive impairment (MMSE<18), the only associated factor was a higher MMSE score. CONCLUSIONS: The results of the present study suggest that both good cognition and good nutritional status are associated with functional improvement in older persons. However, patients with poor cognition can also improve, depending on their degree of cognitive impairment, and they should not be routinely excluded from rehabilitation.     

Severe systemic adverse reaction to proton pump inhibitors in an infant

Episodes of respiratory distress with chest retraction and wheezing, sometimes associated with facial edema, were noted after administering the proton pump inhibitors omeprazole and esomeprazole in an infant with gastroesophageal reflux. The disturbances relieved dramatically after withdrawing the proton pump inhibitor.     

Degenerative disease of the spine

Degenerative disease of the spine is a definition that includes a wide spectrum of degenerative abnormalities. Degeneration involves bony structures and the intervertebral disk, although many aspects of spine degeneration are strictly linked because the main common pathogenic factor is identified in chronic overload. During life the spine undergoes continuous changes as a response to physiologic axial load. These age-related changes are similar to pathologic degenerative changes and are a common asymptomatic finding in adults and elderly persons. A mild degree of degenerative changes is paraphysiologic and should be considered pathologic only if abnormalities determine symptoms. Imaging allows complete evaluation of static and dynamic factors related to degenerative disease of the spine and is useful in diagnosing the different aspects of spine degeneration.     

Rapid maxillary expansion in children with obstructive sleep apnea syndrome: 12-month follow-up

OBJECTIVES: To assess the outcome of rapid maxillary expansion in the treatment of obstructive sleep apnea syndrome (OSAS) in children, we studied 16 patients (mean age 6.6+/-2.0; 9 males) with dental malocclusion, a body mass index < or =85 percentile, and OSAS confirmed by polysomnography. METHODS: At baseline and after the trial, all patients underwent physical examination, standard polysomnography and orthodontic assessment. The Brouillette questionnaire investigating symptoms of OSA was administered to parents before and during the trial to assess the clinical severity of their sleep-disordered breathing. Two treated patients were lost to follow-up and excluded from the final study. RESULTS: In the 14 treated subjects who completed the study and follow-up, polysomnography showed a significant decrease in the apnea-hypopnea index (p=0.005), hypopnea obstructive index (p=0.002) and arousal index (p=0.001). Questionnaire responses before and after treatment showed a significant decrease in the severity of symptoms. CONCLUSION: A rapid maxillary expander is an effective appliance for treating children with OSAS.     

Translation, validation and cultural aspects of postpartum depression screening scale in Brazilian Portuguese

The aim of this study was to determine the validity and reliability of a Portuguese version of the Postpartum Depression Screening Scale (PDSS). A total of 120 new mothers completed the translated version of PDSS and later were interviewed using the Structured Clinical Interview for DSM-IV Axis I Disorders, our gold standard for clinical status. The best cut-off score for the Portuguese version was 102, with a sensibility of 94%, a specificity of 95%, a positive predictive value of 75% and a negative predictive value of 99%. Reliability, measured by the alpha coefficient of internal consistency, was .95. The PDSS is considered ready for use in the screening of Brazilian new mothers for postpartum depression.
