  • This study is aimed at investigated and compared the differences in the affect of hospital specialization according to hospital size using claims data of the Health Insurance and Review Assessment National Inpatient Sample in 2018 for diseases of the musculoskeletal system and connective tissue. To this end, we used multivariate hierarchical linear models(a.k.a., multi-level models) using two-tier data from 106,599 patients discharged after diseases of the musculoskeletal system and connective tissue from 734 hospitals. Multivariate results indicate that patients who were discharged with diseases of the musculoskeletal system and connective tissue from specialized hospitals with 200 beds or less stayed shorter and paid less inpatient charge than those who were discharged from less specialized hospitals. But for hospitals with 201-300 beds, no positive impact relationship was found between hospital specialization and operational performance. This finding may be limited evidence that the affect of a hospital's specialization strategy may vary depending on the size of the hospital. We discussed several managerial and health policy implications below.

  • Connective tissue diseases (CTDs) can affect all compartments of the lungs, including airways, alveoli, interstitium, vessels, and pleura. CTD-associated lung diseases (CTD-LDs) may present as diffuse lung disease or as focal lesions, and there is significant heterogeneity between the individual CTDs in their clinical and pathological manifestations. CTD-LDs may presage the clinical diagnosis a primary CTD, or it may develop in the context of an established CTD diagnosis. CTD-LDs reveal acute, chronic or mixed pattern of lung and pleural manifestations. Histopathological findings of diverse morphological changes can be present in CTD-LDs airway lesions (chronic bronchitis/bronchiolitis, follicular bronchiolitis, etc.), interstitial lung diseases (nonspecific interstitial pneumonia/fibrosis, usual interstitial pneumonia, lymphocytic interstitial pneumonia, diffuse alveolar damage, and organizing pneumonia), pleural changes (acute fibrinous or chronic fibrous pleuritis), and vascular changes (vasculitis, capillaritis, pulmonary hemorrhage, etc.). CTD patients can be exposed to various infectious diseases when taking immunosuppressive drugs. Histopathological patterns of CTD-LDs are generally nonspecific, and other diseases that can cause similar lesions in the lungs must be considered before the diagnosis of CTD-LDs. A multidisciplinary team involving pathologists, clinicians, and radiologists can adequately make a proper diagnosis of CTD-LDs.

  • Anterior abdominal scintigraphy after intravenous injection of $^{99m}Tc$-human serum albumin ($^{99m}Tc$-HSA 20 mCi) was done in 16 patients with connective tissue diseases and 15 healthy control patients. Patients with proteinuria or hepatopathy were excluded. 1) 7 (44%) patients among 16 connective tissue disease patients without the apparent evidence of external protein loss showed abnormal intestinal accumulation of albumin. 6 patients with positive albumin scintigraphy showed bypoalbuminemia. 2) There was no false positive scintigraphic finding in control group. 3) The serum albumin level in connective tissue disease patients ($3.1{\pm}0.6 g/dl$, n=16) was lower than control patients ($3.9{\pm}0.3 g/dl$, n=15) (p<0.0001). 4) The serum albumin level was lower in connective tissue disease patients with positive $^{99m}Tc$-HSA scan ($2.8{\pm}0.6 g/dl$, n=7) than the connective tissue disease patients with negative scan ($3.3{\pm}0.3 g/dl$, n=9) (p<0.05). 5) The hemoglobin level in connective tissue disease patients with positive nan ($10.6{\pm}2.91 g/dl$) was lower than that of the control group ($13.6{\pm}1.5 g/dl$) (p<0.05). Mypoalbuminemia is frequently involved in chronic connective tissue diseases. Protein losing enteropathy (PLE) is also responsible for the majority of the bypoalbuminemia in these patients. But it has been ignored because the conventional method for the diagnosis of PLE was difficult to perform. $^{99m}Tc$-HSA scan also must be validated by more extended study and comparison with the quantitative study such as stool ${\alpha}-1$ antitrypsin measurement. There must be a reevaluation of PLE in various diseases especially in connective tissue diseases with easy, fast, economical, and non-invasive method.

  • Interstitial lung diseases are heterogeneous entities with diverse clinical presentations. Among them, idiopathic pulmonary fibrosis and connective tissue disease-associated interstitial lung disease are specific categories that pulmonologists are most likely to encounter in the clinical field. Despite the accumulated data from extensive clinical trial and observations, we continue to have many issues which need to be resolved in this field. In this update, we present the review of several articles regarding the clinical presentation, prognosis and treatment of patients with idiopathic pulmonary fibrosis or connective tissue disease-associated interstitial lung disease.

  • Eosinophilic pleural effusion (EPE) is defined as a pleural effusion that contains at least 10% eosinophils. EPE occurs due to a variety of causes such as blood or air in the pleural space, infection, malignancy, or an autoimmune disease. Undifferentiated connective tissue disease (UCTD) associated with eosinophilic pleural effusion is a rare condition generally characterized by the presence of the signs and symptoms but not fulfilling the existing classification criteria. We report a case involving a 67-year-old man with UCTD and EPE, who has been successfully treated with a single intrapleural corticosteroid injection.

  • Connective tissue disease (CTD) is a collection of disorders characterized by various signs and symptoms such as circulation of autoantibodies in the entire system causing damage to internal organs. Interstitial lung disease (ILD) which is associated with CTD is referred to as CTD-ILD. Patients diagnosed with ILD should be thoroughly examined for the cooccurrence of CTD, since the treatment procedures and prognosis of CTD-ILD are vary from those of idiopathic interstitial pneumonia. The representative types of CTD which may accompany ILD include rheumatoid arthritis, systemic sclerosis (SSc), Sjogren's syndrome, mixed CTD, idiopathic inflammatory myopathies, and systemic lupus erythematous. Of these, ILD most frequently co-exists with SSc. If an ILD is observed in the chest, high resolution computed tomography and specific diagnostic criteria for any type of CTD are met, then a diagnosis of CTD-ILD is made. It is challenging to conduct a properly designed randomized study on CTD-ILD, due to low incidence. Therefore, CTD-ILD treatment approach is yet to been established in absence of randomized controlled clinical trials, with the exception of SSc-ILD. When a patient is presented with acute CTD-ILD or if symptoms occur due to progression of the disease, steroid and immunosuppressive therapy are generally considered.

  • Purpose: Fever is one of the most common symptoms in children. In previous studies, infectious disease was the most common cause of pediatric fever of unknown origin (FUO). The aim of this study is to investigate the etiology, clinical characteristics and prognosis of pediatric FUO in 21 century with more diagnostics available and to analyze the factors for certain disease categories. Methods: Among the children under 18 years old who were hospitalized at Samsung Medical Center from January 2000 to December 2014, the patients who met the criteria including fever of ${\geq}38.0^{\circ}C$ for longer than ${\geq}14days$ and failure to reach a diagnosis after one week of investigations were included. Results: Total 100 patients were identified. Confirmed diagnosis was achieved in 57 patients (57%). Among them, infectious diseases (n=19, 19%) were most common, followed by connective tissue diseases (n=15, 15%), necrotizing lymphadenitis (n=8, 8%), and malignancies (n=7, 7%). Children with fever duration over 28 days had a trend for higher frequency of connective tissue diseases (28.3%) except undiagnosed etiology. The symptoms such as arthritis, lymph node enlargement and only fever without other symptoms were significantly related with connective tissue diseases, necrotizing lymphadenitis and undiagnosed respectively (P<0.001). Ninety-two patients have become afebrile at discharge and 1 patient died (1%). Conclusion: Almost half of our patients were left without diagnosis. Although it has been known that infectious disease was most common cause of pediatric FUO in the past, undiagnosed portion of FUO have now increased due to development of diagnostic techniques for infectious diseases.

  • Background: In this study, influence caused by expression plasmids of connective tissue growth factor (CTGF) and tissue inhibitor of metalloproteinase-1 (TIMP-1) short hairpin RNA (shRNA) on mRNA expression of CTGF,TIMP-1,procol-${\alpha}1$ and PCIII in hepatic tissue with hepatic fibrosis, a precancerous condition, in rats is analyzed. Materials and Methods: To screen and construct shRNA expression plasimid which effectively interferes RNA targets of CTGF and TIMP-1 in rats. 50 cleaning Wistar male rats are allocated randomly at 5 different groups after precancerous fibrosis models and then injection of shRNA expression plasimids. Plasmid psiRNA-GFP-Com (CTGF and TIMP-1 included), psiRNA-GFP-CTGF, psiRNA-GFP-TIMP-1 and psiRNA-DUO-GFPzeo of blank plasmid are injected at group A, B, C and D, respectively, and as model control group that none plasimid is injected at group E. In 2 weeks after last injection, to hepatic tissue at different groups, protein expression of CTGF, TIMP-1, procol-${\alpha}1$ and PC III is tested by immunohistochemical method and,mRNA expression of CTGF,TIMP-1,procol-${\alpha}1$ and PCIII is measured by real-time PCR. One-way ANOVA is used to comparison between-groups. Results: Compared with model group, there is no obvious difference of mRNA expression among CTGF,TIMP-1,procol-${\alpha}1$, PC III and of protein expression among CTGF, TIMP-1, procol-${\alpha}1$, PC III in hepatic tissue at group injected with blank plasmid. Expression quantity of mRNA of CTGF, TIMP-1, procol-${\alpha}1$ and PCIII at group A, B and C decreases, protein expression of CTGF, TIMP-1, procol-${\alpha}1$, PC III in hepatic tissue is lower, where the inhibition of combination RNA interference group (group A) on procol-${\alpha}1$ mRNA transcription and procol-${\alpha}1$ protein expression is superior to that of single interference group (group B and C) (P<0.01 or P<0.05). Conclusions: RNA interference on CTGF and/or TIMP-1 is obviously a inhibiting factor for mRNA and protein expression of CTGF, TIMP-1, procol-${\alpha}1$ and PCIII. Combination RNA interference on genes of CTGF and TIMP-1 is superior to that of single RNA interference, and this could be a contribution for prevention of precancerous condition.

  • A study of pulmonary diseases in the slaughtered cattle (n = 125) of Mymensingh town was conducted to study pathological findings using the standard methods from September 2001 through April 2002. The pulmonary lesions observed in this study included congestion, emphysema, anthracosis, pleuritis abscess and hemorrhage. The histopathological findings of congestion were characterized by hemorrhage, a large number of leukocytes infiltration in the lumen of the alveoli, bronchitis, bronchiolitis, proliferation of fibrous connective tissue and hyperplasia of bronchiolar epithelia. Histopathologically, emphysema was identified by the distended alveoli with thin and atrophied alveolar walls. In anthracosis, carbon particles were found in stroma and alveolar lumen. In pleuritic lesions, there was a proliferation of fibrous connective tissue along with the infiltration of mononuclear reactive cells. Abscesses were characteristic of the accumulation of neutrophils surrounded by immature fibroblasts forming a capsule like structure.
