Abstract
OBJECTIVE This study aimed to determine the effects of a neuropsychosocial teleassistance group-based intervention on improving social cognitive functioning and health-related quality of life (HRQoL) in pediatric neuromuscular diseases (NMD). METHODS Thirty-five pediatric patients with NMD were assigned to the neuropsychosocial intervention program (n = 20) or waiting list control condition (n = 15). The intervention group received an integrative approach that combines training in social cognition with cognitive behavioral therapy. All participants completed a neuropsychological and clinical assessment at baseline and follow-up, which included tests of social cognition, both for emotion recognition and theory of mind, and HRQoL. Repeated-measures multivariate analysis of covariance was used to determine the effects of the teleassistance program. RESULTS Group × Time interactions revealed significant improvements in the intervention group as compared with the control group for different social cognition's indicators (AR NEPSY-II: p = .003, η2p = .24; TM NEPSY: p < .001, η2p = .35; Verbal task: p < .001, η2p = .35; Happé's Strange Stories: p = .049, η2p = .11) and HRQoL (Psychosocial health: p = .012, η2p = .18; Emotional functioning: p = .037, η2p = 0.13; Social functioning: p = .006, η2p = .21; Total: p = .013, η2p = .17), showing medium to large effects. CONCLUSIONS Patients receiving the neuropsychosocial intervention showed improvements in their social cognition performance and psychosocial HRQoL, providing evidence about the positive effects of the program in pediatric patients with NMD. This should be considered in further research and interventions in this field.

Abstract
Chiari malformation has been classified as a group of posterior cranial fossa disorders characterized by hindbrain herniation. Chiari malformation type I (CM-I) is the most common subtype, ranging from asymptomatic patients to those with severe disorders. Research about clinical manifestations or medical treatments is still growing, but cognitive functioning has been less explored. The aim of this systematic review is to update the literature search about cognitive deficits in CM-I patients. A literature search was performed through the following electronic databases: MEDLINE, PsychINFO, Pubmed, Cochrane Library, Scopus, and Web of Science. The date last searched was February 1, 2023. The inclusion criteria were as follows: (a) include pediatric or adult participants with a CM-I diagnosis, (b) include cognitive or neuropsychological assessment with standardized tests, (c) be published in English or Spanish, and (d) be empirical studies. Articles that did not report empirical data, textbooks and conference abstracts were excluded. After the screening, twenty-eight articles were included in this systematic review. From those, twenty-one articles were focused on adult samples and seven included pediatric patients. There is a great heterogeneity in the recruited samples, followed methodology and administered neurocognitive protocols. Cognitive functioning appears to be affected in CM-I patients, at least some aspects of attention, executive functions, visuospatial abilities, episodic memory, or processing speed. However, these results require careful interpretation due to the methodological limitations of the studies. Although it is difficult to draw a clear profile of cognitive deficits related to CM-I, the literature suggests that cognitive dysfunction may be a symptom of CM-I. This suggest that clinicians should include cognitive assessment in their diagnostic procedures used for CM-I. In summary, further research is needed to determine a well-defined cognitive profile related to CM-I, favoring a multidisciplinary approach of this disorder.

Abstract
The aim of this study was to compare the effects of the pandemic on health-related quality of life (HRQoL), anxious-depressive symptoms, feelings of loneliness, and fear of COVID-19 between people with myasthenia gravis (MG) and healthy controls. We also wanted to know in which group the variable fear of COVID-19 interfered the most with the results. This cross-sectional study involved 60 people with MG and 60 healthy controls. Participants using an online platform completed a sociodemographic questionnaire, the Short Form-36 Health Survey (SF-36), the Hospital Anxiety and Depression Scale (HADS), the revised UCLA Loneliness Scale and the Fear of COVID19 Scale (FCV- 19S). The MG group reported worse levels in HRQoL indicators (p = 0.043- <.001), more severe anxiety-depressive symptoms (p = 0.002), and greater fear of COVID-19 (p < 0.001), but there were no differences in feelings of loneliness (p = 0.002). Furthermore, after controlling for the effect of the fear of COVID-19 variable, the differences remained for physical health indicators, but not for the most of psychosocial indicators (Social Functioning p = 0.102, η2p = 0.023; Role Emotional p = 0.250, η2p = 0.011; and HADS Total p = 0.161, η2p = 0.017). The harmful effect of the COVID-19 pandemic was greater in the MG group, and the perceived fear of COVID-19 had also a greater impact among this group, which has increased its negative effect on their psychosocial health.

Abstract
Virus from the Mononegavirales order share common features ranging from virion structure arrangement to mechanisms of replication and transcription. One of them is the way the nucleoprotein (N) wraps and protects the RNA genome from degradation by forming a highly ordered helical nucleocapsid. However, crystal structures from numerous Mononegavirales reveal that binding to the nucleoprotein results in occluded nucleotides that hinder base pairing necessary for transcription and replication. This hints at the existence of alternative conformations of the N protein that would impact on the protein-RNA interface, allowing for transient exposure of the nucleotides without complete RNA release. Moreover, the regulation between the alternative conformations should be finely tuned. Recombinant expression of N from the respiratory syncytial virus form regular N/RNA common among all Mononegavirales, and these constitute an ideal minimal unit for investigating the mechanisms through which these structures protect RNA so efficiently while allowing for partial accessibility during transcription and replication. Neither pH nor high ionic strength could dissociate the RNA but led to irreversible aggregation of the nucleoprotein. Low concentrations of guanidine chloride dissociated the RNA moiety but leading to irreversible aggregation of the protein moiety. On the other hand, high concentrations of urea and long incubation periods were required to remove bound RNA. Both denaturants eventually led to unfolding but converged in the formation of an RNA-free β-enriched intermediate species that remained decameric even at high denaturant concentrations. Although the N-RNA rings interact with the phosphoprotein P, the scaffold of the RNA polymerase complex, this interaction did not lead to RNA dissociation from the rings in vitro. Thus, we have uncovered complex equilibria involving changes in secondary structure of N and RNA loosening, processes that must take place in the context of RNA transcription and replication, whose detailed mechanisms and cellular and viral participants need to be established.

Abstract
UNLABELLED Sleep disturbance has been described in cystic fibrosis (CF) patients as relevant to clinical and lung function predictive factors helping to improve the diagnosis and early intervention. Related paediatric studies are scarce. OBJECTIVE To describe respiratory sleep disturbance (RSD) and its association with spirometric indices in a population of CF children. A second aim was to determine if spirometric indices and wake-time SpO2 are predictors of sleep disturbance. METHODS A cross-sectional study involving 33CF paediatric patients. All participants underwent in-lab polysomnography (PSG), pulse oximetry and spirometry. A standardized sleep questionnaire was completed for each patient. Two subgroups were considered: I - Normal (FEV1>-1.64 z-score); II - Obstructed (FEV1≤-1.64 z-score). RESULTS Participant's median age was 12 (6-18) years, 16 (48.5%) were male. Twenty-nine patients (87.9%) presented sleep complaints. Sleep efficiency was reduced; sleep latency and waking after sleep onset (WASO) increased. N1 increased, N2, N3, REM and awakenings were normal. The apnoea-hypopnoea index was 0.6/h (sd 0.9); respiratory disturbance index (RDI) was 6.6/h (sd 5.2). Mean awaking (97% (sd 1.1)) and sleep SpO2 (95% (sd 2.7)) were normal; mean nocturnal oximetry desaturation index was 2.36/h; minimal nocturnal SpO2 was 89% (sd 4.1). We found associations between mean nocturnal SPO2 and mean values of FEV1 (r=0.528; p=0.002) and FEF25-75 (r=0.426; p=0.013). There were significant differences in nocturnal SpO2 between normal and obstructed patients (p<0.000). PSG data correlated with the questionnaire answers for night awakenings and WASO (p=0.985) and difficult breathing during sleep and RDI (p=0.722). This study points to most CF children having sleep complaints, and highlights the correlation between subjective assessment of sleep and PSG and spirometric results. Awake-time SpO2 and spirometric values are possible risk predictors for nocturnal desaturation.

Abstract
Background In contrast with the recommendations of clinical practice guidelines, the most common treatment for anxiety and depressive disorders in primary care is pharmacological. The aim of this study is to assess the efficacy of a cognitive-behavioural psychological intervention, delivered by primary care psychologists in patients with mixed anxiety-depressive disorder compared to usual care. Methods/Design This is an open-label, multicentre, randomized, and controlled study with two parallel groups. A random sample of 246 patients will be recruited with mild-to-moderate mixed anxiety-depressive disorder, from the target population on the lists of 41 primary care doctors. Patients will be randomly assigned to the intervention group, who will receive standardised cognitive-behavioural therapy delivered by psychologists together with usual care, or to a control group, who will receive usual care alone. The cognitive-behavioural therapy intervention is composed of eight individual 60-minute face-to face sessions conducted in eight consecutive weeks. A follow-up session will be conducted over the telephone, for reinforcement or referral as appropriate, 6 months after the intervention, as required. The primary outcome variable will be the change in scores on the Short Form-36 General Health Survey. We will also measure the change in the frequency and intensity of anxiety symptoms (State-Trait Anxiety Inventory) and depression (Beck Depression Inventory) at baseline, and 3, 6 and 12 months later. Additionally, we will collect information on the use of drugs and health care services. Discussion The aim of this study is to assess the efficacy of a primary care-based cognitive-behavioural psychological intervention in patients with mixed anxiety-depressive disorder. The international scientific evidence has demonstrated the need for psychologists in primary care. However, given the differences between health policies and health services, it is important to test the effect of these psychological interventions in our geographical setting. Trial registration NCT01907035 (July 22, 2013).

Abstract
BACKGROUND The Revised version of the Fibromyalgia Impact Questionnaire (FIQR) was published in 2009. The aim of this study was to prepare a Spanish version, and to assess its psychometric properties in a sample of patients with fibromyalgia. METHODS The FIQR was translated into Spanish and administered, along with the FIQ, the Hospital Anxiety Depression Scale (HADS), the 36-Item Short-Form Health Survey (SF-36), and the Brief Pain Inventory (BPI), to 113 Spanish fibromyalgia patients. The administration of the Spanish FIQR was repeated a week later. RESULTS The Spanish FIQR had high internal consistency (Cronbach’s α was 0.91 and 0.95 at visits 1 and 2 respectively). The test-retest reliability was good for the FIQR total score and its function and symptoms domains (intraclass correlation coefficient (ICC > 0.70), but modest for the overall impact domain (ICC = 0.51). Statistically significant correlations (p < 0.05) were also found between the FIQR and the FIQ scores, as well as between the FIQR scores and the remaining scales’ scores. CONCLUSIONS The Spanish version of the FIQR has a good internal consistency and our findings support its validity for assessing fibromyalgia patients. It might be a valid instrument to apply in clinical and investigational grounds.

Abstract
Opioid analgesia is compromised by intracellular mediators such as protein kinase C (PKC). The phosphatidylinositol hydrolysis-coupled serotonin receptor 5-HT2 is ideally suited to promote PKC activation. We test the hypothesis that 5-HT2A and 5-HT2B receptors, which have been previously shown to become pro-excitatory after spinal nerve ligation (SNL), can negatively influence the ability of opioids to depress spinal excitation evoked by noxious input. Spinal superfusion with (100 nM) mu-opioid receptor (MOR)-agonist DAMGO significantly depressed C fiber-evoked spinal field potentials. Simultaneous administration of subclinical 5-HT2AR antagonist 4F 4PP (100 nM) or 5-HT2BR antagonist SB 204741 (100 nM) significantly reduced the IC50 value for DAMGO in nerve-ligated rats (97.56 nM ± 1.51 and 1.20 nM ± 1.28 respectively, relative to 104 nM ± 1.08 at the baseline condition), but not in sham-operated rats. Both antagonists failed to alter depression induced by delta-opioid receptor (DOR)-agonist D-ala2-deltorphin II after SNL as well as in the sham condition. Western blot analysis of dorsal horn homogenates revealed bilateral upregulation of 5-HT2AR and 5-HT2BR protein band densities after SNL. As assessed from double immunofluorescence labeling for confocal laser scanning microscopy, scarce dorsal horn cell processes showed co-localization color overlay for 5-HT2AR/MOR, 5-HT2BR/MOR, 5-HT2AR/DOR, or 5-HT2BR/DOR in sham-operated rats. Intensity correlation-based analyses showed significant increases in 5-HT2AR/MOR and 5-HT2BR/MOR co-localizations after SNL. These results indicate that plasticity of spinal serotonergic neurotransmission can selectively reduce spinal MOR mechanisms via 5-HT2A and 5-HT2B receptors, including upregulation of the latter and increased expression in dorsal horn neurons containing MOR.

Abstract
Clinical presentation of fibromyalgia syndrome (FMS) is heterogeneous and often involves psychological comorbidities. Clinical subgrouping of FMS patients has been proposed as a strategy to improve patients' long-term outcomes by helping identify specific treatment needs. Using the 90 Symptom Checklist Revised (SCL-90-R), we have assessed emotional distress in two FMS patient subpopulations discriminated on the basis of their differences in scores on specific items of the Fibromyalgia Impact Questionnaire (FIQ). Subjects classed as type II exhibited high emotional distress on all ten dimensions studied, which included somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, psychoticism, and additional items subscales, as well as on the global severity index (GSI), positive symptom total (PST), and positive symptom distress index (PDSI). T-scores in these patients were above diagnostic cutoff level of 60 on somatization, obsessive-compulsive, and depression subscales. In contrast, the profile exhibited by type I subjects fell entirely within normal values for nonpsychiatric population. Emotional status was significantly inversely correlated with present clinical pain in type I-, but not in type II-fibromyalgia patients. Regression analysis revealed a model based on phobic anxiety, paranoid ideation, and depression subscales as best contributing to classification. The present data suggest that associated psychological distress and maladaptive emotional responses that are commonly attributed to the general FMS population may be largely a distinguishing feature of one subset of patients.

Abstract
INTRODUCTION Tobacco smoke is a risk factor for Chronic Obstructive Pulmonary Disease and a major public health problem. Prenatal maternal smoking and post-natal environmental tobacco smoke (ETS) lead to dose-dependent decrease in lung function and respiratory morbidity. Influence of different socioeconomic indicators and ETS in the home has also been suggested. METHODS Data on 313 children (52 % male) from 4 public schools in Lisbon was analyzed [1st (46 %) and 4th graders]. ETS assessment and respiratory symptoms were based on a self-answered questionnaire. All children performed standard spirometry in the school setting and 54 % were acceptable according to ATS/ERS criteria. Descriptive and bivariate analysis of the most relevant variables was done, followed by multiple logistic regression analysis adjusted to the variables with clinical/statistical relevance. RESULTS ETS in the home was found in 41 % (maternal smoking during pregnancy 18 %, smoking mother 32 %, smoking father 38 %). Smoking fathers had lower education and less qualified occupation. Cough was more frequent in children with a smoking mother (adjusted OR = 2.1 95CI 1.1-4.0) and wheezing in children with maternal smoking during pregnancy and smoking parents. All differences were significant (p < 0.05). No association was found between parental education and cough/wheeze or ETS and respiratory infections/asthma/decreased spirometric values. CONCLUSIONS Children in Lisbon are frequently exposed to ETS which results in significant respiratory morbidity. Targeted interventions must have social conditions in consideration. In this study, field spirometry was not helpful in early detection of lung function disability in children associated with ETS.

Abstract
Skin inflammation plays an important role during the healing of American tegumentary leishmaniasis (ATL), the distribution of cells in active lesions may vary according to disease outcome and parasite antigens in ATL scars have already been shown. We evaluated by immunohistochemistry, 18 patients with 1- or 3-year-old scars and the corresponding active lesions and compared them with healthy skin. Small cell clusters in scars organized as in the active lesions spreaded over the fibrotic tissue were detected, as well as close to vessels and cutaneous glands, despite a reduction in the inflammatory process. Analysis of 1-year-old scar tissue showed reduction of NOS2, E-selectin, Ki67, Bcl-2 and Fas expression. However, similar percentages of lymphocytes and macrophages were detected when compared to active lesions. Only 3-year-old scars showed reduction of CD3(+), CD4(+) and CD8(+)T cells, in addition to reduced expression of NOS2, E-selectin, Ki67 and BCl-2. These results suggest that the pattern of cellularity of the inflammatory reaction observed in active lesions changes slowly even after clinical healing. Analysis of 3-year-old scars showed reduction of the inflammatory reaction as demonstrated by decrease in inflammatory cells and in the expression of cell-activity markers, suggesting that the host-parasite balance was only established after that period.

Abstract
Neurotransmitter serotonin (5-HT) released from descending pain modulation pathways to the dorsal horn is crucial to spinal nociception processing. This study sought to gain insight into the modulatory roles of specific serotonin receptor subtypes in experimentally induced neuropathic pain. In rats subjected to spinal nerve ligation (SNL) surgery, we recorded field potentials evoked in the spinal dorsal horn by C fibre-input, during spinal superfusion with subtype-selective drugs. In neuropathic rats, subtype 5-HT1A agonist 8-OH-DPAT (100 nM) was found to potently depress evoked field potentials, as opposed to 5-HT2A or 5-HT2B subtype agonists TCB-2 (100 nM) or BW 723C86 (1 microM), respectively, which consistently enhanced evoked potentials. All three failed to alter spinal field potentials in sham operated rats. CP 94253 (1 microM), WAY 161503 (1 mM) or SR 57227 (at 1 microM in SNL rats, and 100 microM in sham rats), selective agonists for 5-HT1B, 5-HT2C and 5-HT3 receptors, respectively, significantly depressed evoked field potentials in both animal groups. The 5-HT4 agonist RS 67333 (1 microM) was depressant only in sham operated animals. Only after SNL, spinal superfusion with 5-HT1A- or 5-HT1B receptor-antagonists (S)-WAY 100135 (100 microM) or SB 224289 (100 microM), respectively, disinhibited C fibre-evoked potentials, whereas 5-HT2A or 5-HT2B receptor-antagonists 4F 4PP (100 microM) or SB 204741 (100 microM) depressed evoked potentials, suggesting tonic activity of all four subtypes as a consequence of experimental nerve injury. The present findings reveal profound subtype-specific changes in the functional modulatory activities of spinal serotonin receptors following peripheral nerve injury. In particular, spinal hyperexcitation promoted by receptors 5-HT2A and 5-HT2B is suggested as a novel pathogenic pathway contributing to neuropathic pain.

Abstract
BACKGROUND The study of American tegumentary leishmaniasis (ATL) lesions might contribute to the understanding of the dynamics of the infection. OBJECTIVES To examine the cellular infiltrate of cutaneous ATL lesions and to compare these results with the detection of the parasites and clinical data. METHODS Lesions of 19 patients with ATL were evaluated through immunohistochemical analysis. RESULTS The lesions presented an inflammatory reaction mainly consisting of T cells and macrophages. Analysis of the expression of nitric oxide synthase type 2 (NOS2) showed that its intensity was directly correlated with the number of CD3+ T cells. We also observed an association between high NOS2 expression and low quantity of parasites, highlighting the importance of NOS2 in the elimination of parasites. CONCLUSIONS The present results suggest that (i) the inflammatory process is intense in cutaneous ATL lesions and maintains a similar activity for several months; (ii) the dynamics of cell infiltration change during this period, with a gradual decrease in CD8+ T cells, probably correlated with a reduction in the parasite number; (iii) neutrophils may participate in the inflammatory process even during later stages of infection; (iv) the relative increase in the number of CD4+ T cells associated with the onset of fibrosis may suggest a participation of these cells in the control of the inflammatory process; and (v) late lesions with tendency for healing usually show focal inflammation. The study of healing lesions might contribute to the understanding of the late steps of the control of the inflammatory process in ATL lesions.

Abstract
Pulmonary surfactant is a lipoproteic mixture synthesized and secreted by alveolar type II cells. Its principal property is to reduce the surface tension by lining on the alveolar surface. Surfactant deficiency is the major factor responsible for the respiratory distress syndrome of the newborn (RDS) and the adult respiratory distress syndrome (ARDS). Since 1980, the exogenous administration of surfactant for the treatment of these syndromes is being studied. In this work the exogenous surfactant preparations, the delivery techniques and the dosing schedule is discussed. The utilization of the exogenous natural surfactant (ENS) as precursor of a radiopharmaceutical labeled with 99mTc (99mTc-ENS) for aerial lung scintigraphy is also discussed.

Abstract
Pulmonary tuberculosis remains as a significant clinical problem in the elderly. To describe age-related differences in disease manifestations, a comparison was made taking in consideration predisposing factors, clinical features, radiographic findings and diagnostic approaches in cases of pulmonary tuberculosis between two groups: equal o higher of 60 years and lower of 60 years. Elderly patients had a higher number of antecedents of previous tuberculosis and underlying diseases than younger patients. At admission, symptoms like fever and hemoptysis were more frequent in the younger group. Radiographic findings revealed that upper lung infiltrates were still common in both groups, and that elderly patients presented less pleural effusions and cavitary lesions than younger patients. Since there were differences in the clinical presentations of pulmonary tuberculosis in the elderly group, a high index of suspicion for the disease should be maintained.

Abstract
An exhaustive search for the clinical records of patients diagnosed with tuberculous disease was done in the hospitals of the area under study, which involves 392,000 population. During the years 1992, 1993 and 1994. There were included: 1) patients who had positive bacilloscopy and/or positive Lowenstein's culture in any specimen: 2) patients younger than 35-years-old who had pleural effusion, significant Mantoux and adenosine deaminase (ADA) over 47 U/I in the pleural effusion. In total 814 patients remained in the study with an average age of 38.39(19.39 DE) in 1992, 39.02 (20.04 DE) in 1993, and 34.1 years-old (19.2 DE) in 1994, with extreme ages of 2 months and 87 years-old. The incidence/100,000 H was: in 1992: 67.86, in 1993: 66.58 and in 1994: 73.2. The contagious forms incidence/100,000 H was: 1.5 in 1992 and 1993; and 1.79 in 1994. The hospital mortality incidence/100,000 H was 2.04 in 1992, 2.30 in 1993 and 2.6 in 1994. We conclude that tuberculosis is endemic in our area with moderately high and stationary incidence.

Abstract
BACKGROUND Pleural biopsy is usually considered important for the diagnosis of pleural effusions, especially for distinguishing between tuberculosis and neoplasia, even though tuberculous pleural fluid contains sensitive biochemical markers. In regions with a high prevalence of tuberculosis, and in patient groups with a low risk of other causes of pleurisy, the positive predictive value of these markers is increased. The criteria for performing a pleural biopsy under these circumstances have been investigated, using adenosine deaminase (ADA) as a pleural fluid marker for tuberculosis. METHODS One hundred and twenty nine patients with a pleural effusion aged < or = 35 years (mean (SD) 25.2 (4.9) years) were studied. Seventy three were men. Eighty one effusions (62.8%) were tuberculous, 12 (9.3%) parapneumonic, and 10 (7.7%) neoplastic, five were caused by pulmonary thromboembolism, four by systemic lupus erythematosus, seven by empyema, three following surgery, one was the result of asbestosis, and one of nephrotic syndrome. In five cases no definitive diagnosis was reached. ADA levels were determined by the method of Galanti and Giusti. RESULTS The diagnostic yield of procedures not involving biopsy was 94.5% (122/129). Pleural biopsy provided a diagnosis in a further two cases, but not in the remaining five. All tuberculous cases had pleural fluid levels of ADA of > 47 U/l (mean (SD) 111.1 (36.6) U/l). The only other cases in which ADA exceeded this level were six of the seven patients with empyema. Cytological examination of the pleural fluid diagnosed eight of the 10 neoplastic cases, compared with six diagnosed by pleural biopsy. CONCLUSIONS In a region with a high prevalence of tuberculosis procedures not involving pleural biopsy have a very high diagnostic yield in patients with a pleural effusion aged < or = 35 years, making biopsy necessary only in cases in which pleural levels of ADA are below 47 U/l, pleural fluid cytology is negative and, in the absence of a positive basis for some other diagnosis, neoplasia is suspected.

Abstract
We compared the parameters pleural adenosine deaminase (PADA, determined in 405 patients), the PADA/serum ADA ratio (P/SADA; 276 cases), pleural lysozyme (PLYS, 276 cases), the PLYS/serum LYS ratio (P/SLYS; 276 cases), and pleural interferon gamma (IFN, 145 cases) regarding their ability to differentiate tuberculous pleural effusions from others. The 405 pleural effusions were classified by previously established criteria as tuberculous (91), neoplastic (110), parapneumonic (58), empyemas (10), transudates (88), or miscellaneous (48). The intermean differences between the tuberculous group and each of the others were statistically significant for all five parameters (p < 0.01 for PLYS and P/SLYS with respect to the empyema group; p < 0.001 otherwise), except for PADA and P/SADA with respect to the empyema group. All the tuberculous pleurisy cases had PADA values of 47 U/L or more, as compared to only 5 percent of the other cases (sensitivity, 100 percent; specificity, 95 percent). P/SADA was above 1.5 in 85.7 percent of tuberculous effusions and 11 percent of the others (sensitivity, 85.7 percent; specificity, 89 percent). PLYS, with a diagnostic threshold of 15 g/ml, had a sensitivity of 85.7 percent and a specificity of 61.6 percent; P/SLYS, with a threshold of 1.1, had a sensitivity of 67.3 percent and a specificity of 90.3 percent; and IFN, with a threshold of 140 pg/ml, had a sensitivity of 94.2 percent and a specificity of 91.8 percent. The lowest misclassification rate was achieved by PADA, with statistically significant differences (p < 0.001) with respect to P/SADA, PLYS, and P/SLYS, but not with respect to IFN. The only significant pairwise correlations among these parameters were between P/SLYS and PADA and between P/SLYS and P/SADA. We conclude that PADA and IFN are useful parameters for early diagnosis of tuberculous pleurisy, and that the other parameters considered have no advantages over PADA and IFN for this purpose (though the high specificity of P/SLYS may be noted).

Abstract
Previously established criteria were used to classify 253 pleural effusions as transudates (65 cases), neoplastic exudates (67 cases), tuberculous exudates (65 cases), or miscellaneous exudate (56 cases). The parameters pleural LDH (PLDH), pleural LDH/serum LDH ratio (P/SLDH), and pleural protein/serum protein ratio (P/SPROT) were compared with pleural cholesterol (PCHOL) and the pleural cholesterol/serum cholesterol ratio (P/SCHOL) with regard to their usefulness for distinguishing between pleural exudates and transudates. The PCHOL values determined were 28.5 +/- 12.8 mg/dl for transudates, 88.1 +/- 30 mg/dl for neoplastic exudates, 96.5 +/- 28 mg/dl for tuberculous exudates, and 88 +/- 35.9 mg/dl for the miscellaneous group; the differences between the transudate group and the others are statistically significant (p less than 0.001). The sensitivity and specificity of P/SPROT for diagnosis of exudates were both 89 percent; the sensitivity of PLDH was 67 percent and its specificity was 95 percent; the sensitivity and specificity of P/SLDH were both 84.6 percent. Using Light's three criteria as a battery, the sensitivity was 94.6 percent and its specificity was 78.4 percent. All the transudates and 17 (9 percent) of the 188 exudates had PCHOL values below 55 mg/dl, so that with this threshold, PCHOL had a sensitivity of 91 percent and a specificity of 100 percent for diagnosis of exudates. With a threshold of 0.3, P/SCHOL had a sensitivity of 92.5 percent and a specificity of 87.6 percent. The number of misclassifications by PCHOL was less than with any other of the parameters, with statistically significant differences with respect to PLDH (p less than 0.001) and P/SLDH (p less than 0.01). We conclude that determination of PCHOL and P/SCHOL is of great value for distinguishing between pleural exudates and transudates, and should be included in routine laboratory analysis of pleural effusions.
