Abstract
IntroductionDysphagia is one of the most clinically significant disabilities in patients with multiple system atrophy (MSA), because it can cause aspiration pneumonia, which is potentially fatal. In this study, the Neuromuscular disease Swallowing Status Scale (NdSSS), which was developed to evaluate dysphagia in patients with neuromuscular diseases, was used to evaluate patients with MSA. In addition, correlation between a history of pneumonia and swallowing function was evaluated.MethodsStudy 1: Reliability, concurrent validity, and responsiveness of the NdSSS in patients with MSA. In 81 patients for whom evaluation items could be collected, the NdSSS was tested for its interrater and intrarater reliability using weighted kappa statistics. Concurrent validity was assessed by correlating the NdSSS with existing scales (Functional Oral Intake Scale (FOIS), Functional Intake LEVEL Scale (FILS), and the unified MSA rating scale (UMSARS)) using Spearman's rank correlation coefficients. Sixty-three patients were evaluated by videofluorographic (VF) swallowing examination. To evaluate concurrent validity, Spearman's rank correlation coefficients were calculated between the NdSSS and VF swallowing assessments. Additionally, scale responsiveness was determined using the standardized response mean (SRM) in 23 patients who could be followed up to assess their long-term course. Study 2: Cross-sectional survey of swallowing function and history of pneumonia. Data regarding history of pneumonia, UMSARS, NdSSS, age, sex, MSA subtype, and disease duration were retrospectively obtained from the medical records of 113 patients with MSA. Differences in these parameters and NdSSS stage between those with and without a history of pneumonia were examined using the Mann-Whitney test or chi-squared test. Furthermore, clinical factors related to a history of pneumonia were examined by binomial logistic regression analysis.ResultsThe NdSSS showed satisfactory reliability, concurrent validity, and responsiveness. A history of pneumonia was related to the severity of MSA, age, MSA subtype, and NdSSS stage. Binomial logistic regression analysis showed that NdSSS stage (odds ratio (OR), 0.490; 95% confidence interval (CI), 0.301–0.797, p = 0.001) and MSA subtype (OR, 4.031; 95% CI, 1.225–13.269, p = 0.021) were significantly associated with a history of pneumonia.ConclusionsIn patients with MSA, the NdSSS has sufficient reliability, concurrent validity, and responsiveness for assessing dysphagia. Patients with a history of pneumonia have more severe dysphagia. We found that the pneumonia risk was related to NdSSS stage and MSA-p (predominantly parkinsonism). Meticulous care to prevent aspiration is needed from early stages of the disease.

Abstract
High circulating serum immunoglobulin G4 (IgG4) levels have been proposed as a marker of autoimmune pancreatitis (AIP). The aim of the present study was to review the data existing in the English literature on the usefulness of the IgG4 serum levels in the diagnosis and follow up of patients with AIP. A total of 159 patients with AIP and 1099 controls were described in seven selected papers reporting the usefulness of serum IgG4 in diagnosing AIP. In total, 304 controls had pancreatic cancer, 96 had autoimmune diseases, and the remaining 699 had other conditions. The summary receiver-operating characteristic curve analysis was carried out by means of Meta-DiSc open-access software. Serum IgG4 showed good accuracy in distinguishing between AIP and the overall controls, pancreatic cancer and other autoimmune diseases (area under the curve [+/- SE]: 0.920 +/- 0.073, 0.914 +/- 0.191, and 0.949 +/- 0.024, respectively). The studies analyzed showed significantly heterogeneous specificity values in each of the three analyses performed. The analysis of the four studies comparing AIP and pancreatic cancers also showed significantly heterogeneous values of sensitivities and odds ratios. Regarding the usefulness of IgG4 as a marker of efficacy of steroid treatment, a decrease in the serum concentrations of IgG4 was found in the four available studies. The serum IgG4 subclass is a good marker of AIP, and its determination should be included in the diagnostic workup of this disease. However, the heterogeneity of the studies published until now means that more studies are necessary in order to better evaluate the true accuracy of IgG4 in discriminating AIP versus other autoimmune diseases.

Abstract
OBJECTIVE To describe the presentation and genetic transmission of ciliary dyskinesia syndrome associated with hydrocephalus and mental retardation in 3 generations of a family. PATIENTS AND METHODS A large Jordanian family included 9 individuals in 3 generations with recurrent pulmonary infections; 4 male siblings have been diagnosed as having mental retardation, and a maternal uncle was believed to have been similarly affected. Chromosome analysis of the family showed a normal karyotype. RESULTS Electron microscopy of the nasal cilia from 3 affected siblings showed features of primary ciliary dyskinesia. Computed tomographic scans of the brains of all 4 affected siblings showed hydrocephalus. CONCLUSIONS The recurrent pulmonary infections and hydrocephalus in this large Jordanian family are likely related to ciliary dyskinesia, which appears to follow an autosomal recessive mode of inheritance. The unusual presentation of ciliary dyskinesia, hydrocephalus, and mental retardation may be due to a new genetic mutation.

Abstract
Alterations of neutrophil functions by tobacco products may play a central role in the pathogenesis of periodontal diseases and several smoking-related systemic diseases. In the present study, we examined the in vitro effects of cigarette smoke on neutrophils at times and concentrations that may be encountered during smoke exposure. We measured the level of smoke exposure in the in vitro system by measuring the levels of nicotine and comparing these to levels in the oral cavity in smokers before and after smoking. We examined both the unstimulated and stimulated release of 2 oxidative burst products: superoxide (O-2) and hydrogen peroxide (H2O2). Salivary washings were collected from 7 smokers (> 1 pack/day) before smoking a cigarette. Immediately after they smoked a cigarette, a second set of washings was collected. In vitro exposure to smoke involved incubating aliquots of neutrophils in phosphate-buffered saline for 1 to 5 minutes. Nicotine and cotinine levels were quantitated using gas chromatography, with detection by electron impact mass spectrometry. Peripheral neutrophils were isolated from medically healthy non-smoking volunteers via a double-density gradient technique and incubated in vitro with whole cigarette smoke for 0 to 5 minutes. Phorbol myristate acetate (PMA; 10(-7) M) was used to stimulate half of the cell aliquots. Superoxide generation was assessed through the superoxide dismutase (SOD) inhibitable reduction of ferricytochrome c. H2O2 production was assessed through the H2O2-dependent breakdown of dichlorofluorescin diacetate to its fluorophore and measured by flow cytometry. There was a marked elevation in salivary nicotine concentration from before smoking (mean: 80.8 ng) to after smoking (mean 1,685 ng/mL). In the in vitro smoke box system, there was a time-related elevation in nicotine from 1 to 5 minutes (50-->136 ng/mL). In PMA-stimulated cells exposed to smoke, there was a time-related inhibition of both superoxide and H2O2 production. However, in unstimulated cells exposed to smoke, there was a time-related increase in the release of superoxide and H2O2. A novel finding in unstimulated cells exposed to smoke was that there appeared to be 2 distinct populations of cells--one of "high" H2O2 producers and one of "low" H2O2 producers. The proportion of high H2O2 producers increased relative to smoke exposure. The relative production of H2O2 in the unstimulated high producers was comparable to PMA-stimulated cells at 5 minutes. This release of superoxide and H2O2 in unstimulated cells exposed to smoke may alter the pathogenic processes both in periodontal diseases and other systemic diseases.

Abstract
Well functioning host defenses in the respiratory tract effectively remove microbes and other debris that reach the conducting airways and alveoli, and this usually prevents infections. People with acute and chronic illnesses can experience failure of any number of these defense mechanisms that allow pneumonia (and bacteremia) to occur, often with considerable morbidity and mortality. People with alcohol-related illnesses are a susceptible group for infections, and many strategies are needed to help them such as moderating alcohol abuse and dependence, providing timely immunizations to create antibody against encapsulated bacteria, anticipating microbial colonization of mucosal areas that can promote infection, giving excellent supporting medical care in crisis situations, and prescribing appropriate antibiotics. New approaches to boosting inflammatory reactions to control lung infections better with cytokines and new immunomodulator therapies must be investigated now.

Abstract
BACKGROUND The alveolar macrophage is believed to be important in the defence of the lung and possibly in the pathogenesis of lung disease. Cell counts in bronchoalveolar lavage fluid have suggested that smokers have an increased number of alveolar macrophages but have not enabled the number to be related to a measure of lung structure. METHODS The number of alveolar macrophages was counted in histological sections from lung resection specimens from a group of smokers and non-smokers. The results were related to a measurement of lung structure obtained by means of an automated morphometric technique and expressed in terms of units of lung volume or of lung surface area. RESULTS The smokers had a significantly increased number of alveolar macrophages per unit lung volume and per unit surface area, through the relative increase was less than has appeared from bronchoalveolar lavage studies. When smokers and non-smokers with similar lung structure were compared the smokers had more alveolar macrophages, indicating that smoking and not loss of lung structure is responsible for the increase. CONCLUSIONS Smokers had more alveolar macrophages than non-smokers when the number was expressed quantitatively with respect to the underlying architecture. Changes in cell populations postulated to be important in the pathogenesis of disease within the lung should be related to lung architecture because this may vary considerably between individuals.

Abstract
The minor discomforts of pregnancy present difficulties for the health care provider as well as for the pregnant woman herself. Management of the various symptoms requires astute observations and the ability to individualize therapy. Knowledge of a variety of treatment options, therefore, allows practitioners to collaborate with their patients in selecting the best therapeutic approach for the specific situation. This three‐part series reviews the common discomforts associated with upper respiratory infections, minor pain, and gastrointestinal problems as they are manifested during pregnancy. Both nonpharmaceutical and pharmaceutical therapies are discussed. Frequent references are made to the Food and Drug Administration (FDA) Risk Factors which categorize both over‐the‐counter and prescribed drugs according to their documented safety for ingestion during pregnancy. Part I, “Managing Upper Respiratory Infections in Pregnancy,” appears in this issue (JNM 32:6); Part II, “Managing Minor Pain in Pregnancy,” will appear in JNM 33:1; and Part III, “Managing Gastrointestinal Problems in Pregnancy,” will appear in JNM 33:2.
