RESUMO
Background@#Emergent diagnosis and treatment are important for the survival of patients with necrotizing soft-tissue infections (NSTIs). Death is the most catastrophic outcome, but limb loss is also one of the most important complications that can have a significant impact on the rest of the patient’s life. The purpose of this study was to identify predictive factors for limb loss caused by NSTIs. @*Methods@#The data of patients at our center who were diagnosed with NSTIs from May 2003 to January 2019 were analyzed retrospectively. The inclusion criteria were patients with a definite diagnosis of NSTI involving the upper or lower limb. A total of 49 patient records were analyzed in terms of demography, laboratory data, microbiological causes, treatment, and final outcome. Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) scores at initial admission were also collected as laboratory data. Final outcomes were classified into survival with limb salvage and survival with limb loss. @*Results@#The limb loss rate was 20.4% (10/49) in our study. On comparison between the limb salvage group and the limb loss group, independent risk factors of limb loss were as follows: presence of hypotension at admission (odds ratio [OR], 8.2; 95% confidence interval [CI], 1.7–38.3; p = 0.008); LRINEC score ≥ 9 (OR, 5.8; 95% CI, 1.3–25.6; p = 0.012), and glucose level > 300 mg/dL (OR, 4.5; 95% CI, 0.9–21.9; p = 0.041). Various microbiological organisms were isolated; the most prevalent specimen was streptococci (32.6%), followed by staphylococci (26.5%). Poor outcomes including limb loss and mortality had no correlation with microbiological organisms. @*Conclusions@#For patients with NSTIs, the presence of hypotension at admission, a high glucose level (> 300 mg/dL), and a high LRINEC score (> 9) were independent risk factors for limb loss.
RESUMO
PURPOSE: Acute kidney injury (AKI) is common in critically ill patients. Serum cystatin C has emerged as a reliable marker of AKI. We sought to assess the value of serum cystatin C for early detection and prediction of renal function recovery in patients with sepsis. MATERIALS AND METHODS: Sepsis patients (113 AKI patients and 49 non-AKI patients) admitted to the intensive care unit (ICU) were included. Serum creatinine and cystatin C levels and glomerular filtration rate were measured on days 0, 1, 3, and 7. RESULTS: Serum cystatin C levels were significantly higher in AKI patients than in non-AKI patients at all time points. Multivariate analysis showed that only serum cystatin C levels on day 0 were associated with AKI development [odds ratio (OR)=19.30; 95% confidence interval (CI)= 2.58–144.50, p<0.001]. Linear mixed model analysis showed significant variation in cystatin C levels between the recovery and non-recovery groups over time (p=0.001). High levels of serum cystatin C at day 0 (OR=1.64; 95% CI=1.00–2.68, p=0.048) were associated with recovery of AKI. CONCLUSION: Serum cystatin C level was found to be associated with the development and worsening of AKI in ICU patients with sepsis.

BACKGROUND: Despite many ongoing, prospective studies on the topic, sepsis still remains one of the main causes of death in hospital. The hormone insulin-like growth factor 1 (IGF-1) has a similar molecular structure to that of insulin. IGF-1 exerts anabolic effects and plays important roles in both normal physiology and pathologic processes. Previous studies have observed low serum IGF-1 level in patients with critical illnesses. Here, we evaluated changes in IGF-1 level based on survival of septic patients. METHODS: We evaluated 140 patients with sepsis and septic shock (21 with sepsis and 119 with septic shock) admitted to the intensive care unit of a university-affiliated hospital in Korea. Serum IGF-1 level was measured on days 0, 1, 3, and 7. Patients with liver disease were excluded from this study. All data were analyzed using SPSS version 20 (SPSS Inc., Chicago, IL, USA). RESULTS: Patients with septic shock had significantly lower serum IGF-1 level on days 1 and 3 than patients without septic shock (p = 0.002 and p = 0.007, respectively). Generally, there was a negative relationship between IGF-1 and serum cortisol levels; however, this relationship was only significant on day 3 (p = 0.029). Furthermore, renin showed significantly negative correlation with IGF-1 on day 3 (p = 0.038). IGF-1 level did not show significant difference between survivors and non-survivors. CONCLUSIONS: Our results showed that IGF-1 was associated with septic shock, and that the IGF-1 axis is severely disrupted in septic patients. Additionally, serum cortisol and renin levels were associated with IGF-1 level.

To assess the risk factors for carbapenem-resistant Acinetobacter baumannii (CRAB) bacteremia and for 30-day mortality in patients with CRAB bacteremia in the intensive care unit (ICU), we conducted a retrospective study in the ICU at Severance Hospital in Korea from January 2008 to December 2009. Patients who acquired CRAB bacteremia in the ICU were enrolled as the case group and patients whose specimens of blood culture, sputum/endotracheal aspirate and urine revealed no AB were enrolled as controls. The case group comprised 106 patients and 205 patients were included as controls. Risk factors independently associated with CRAB bacteremia included prior chemotherapy or radiotherapy treatment (Odds ratio [OR], 3.6; P = 0.003), recent central venous catheter insertion (OR, 5.7; P < 0.001) or abdominal drainage insertion (OR, 21.9; P = 0.004), the number of antibiotics treated with (OR, 1.3; P = 0.016), and respiratory failure in the ICU (OR, 2.5; P = 0.035). The 30-day mortality was 79.8%. Renal failure during ICU stay was independently associated with 30-day mortality (OR, 3.7; P = 0.047). It is important to minimize invasive procedures, and to restrict excessive use of antibiotics, especially in immunocompromised patients, in order to prevent the development of CRAB bacteremia. Greater concern for CRAB bacteremia patients is needed when renal failure develops during ICU stay.

We report a case of Caplan's Syndrome, which presented as multiple pulmonary nodules. A 58-year-old male was admitted to hospital due to multiple pulmonary nodules. In addition, the patient presented with multiple arthritis, and dyspnea on exertion. Rheumatoid arthritis had been diagnosed 35 years ago. The patient had worked as a stonemason for 20 years. Computed Tomography (CT) revealed numerous well-defined tiny nodules scattered in both lungs, which was suspicious of miliary tuberculosis or malignancy. The patient was started on antituberculous medications and referred to our hospital. First, a transbronchial lung biopsy was performed, which showed no evidence of granuloma. It was our opinion that the biopsy was insufficient, and a follow-up video-associated thoracoscopy was performed. The pathological report determined necrotizing granulomatous inflammation and silicosis on background. According to imaging studies, pathologic reports, and clinical symptoms, we concluded that the patient had Caplan's syndrome. We controlled his rheumatic medications, and instructed him to avoid exposure to hazardous dust.

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a technique developed to allow mediastinal staging of lung cancer and also to evaluate intrathoracic lymphadenopathy. In a tuberculosis-endemic area, tuberculosis should be considered as an etiology of mediastinal lymphadenopathy. The aim of this study was to investigate the utility of the routine culture for tuberculosis from specimens of EBUS-TBNA. METHODS: We prospectively performed routine culture for tuberculosis from aspiration or core biopsy specimens got from 86 patients who had undergone EBUS-TBNA due to mediastinal lymphadenopathy between March 2010 and March 2011. RESULTS: A total of 135 lymph node aspiration and 118 core biopsy specimens were included in this analysis. We confirmed the malignancy in 62 (72.9%), tuberculosis in 7 (8.1%), sarcoidosis in 7 (8.1%), asperogillosis in 2 (2.3%) and pneumoconiosis in 2 (2.3%) patients. One lung cancer patient had pulmonary tuberculosis coincidentally and 5 patients had unknown lymphadenopathy. The number of positive culture for Mycobacterium tuberculsosis by EBUS-TBNA is 2 (1.5%) from 135 lymph node aspiration specimens and 2 (1.7%) from 118 core biopsy specimens. Out of eight patients confirmed with tuberculosis, only one patient had positive mycobacterial culture of aspiration specimen from EBUS-TBNA without histopathologic diagnosis. CONCLUSION: These results propose that routine culture for tuberculosis from EBUS-TBNA may not provide additional information for the diagnosis of coincident tuberculous lymphadenitis. However, if there is any possibility of tuberculous lymphadenopathy or pulmonary tuberculosis, it should be considered to perform EBUS-TBNA in patients who have negative sputum AFB smears or no sputum production.

The prevalence of multi-drug resistant tuberculosis (MDR-TB), which is resistant to isoniazid and rifampin, has been increasing in Korea. And the side effects of 2nd line anti-tuberculosis medications, including drug-induced hepatitis, are well known. Although prothionamide (PTH) is one of the most useful anti-TB medications and although TB medication-induced acute hepatitis is a severe complication, there are only a few published case reports about prothionamide induced hepatitis. In this case report, a 22 year old male was diagnosed with pulmonary MDR-TB and was administered 2nd line anti-TB mediations, including PTH. Afterwards, he had a spiking fever and his liver enzymes were more than 5 times greater than the upper limit of the normal range. He was then diagnosed with drug-induced hepatitis by liver biopsy. His symptoms and liver enzyme elevation were improved after stopping PTH. Accordingly, we report this case of an association between PTH and acute hepatitis.

When all the conventional treatments have failed for patients with acute respiratory distress syndrome (ARDS), extracorporeal membrane oxygenation (ECMO) can offer these patients a chance to survive. We report here on a case of successful treatment with prolonged ECMO support for a patient with severe ARDS. A 41-year-old female patient with acute A-viral hepatitis developed pneumonia and progressive ARDS. After tracheostomy, her clinical condition deteriorated despite proper antibiotic administration and other conventional treatments, including the recruitment maneuver and steroid use. Venoarterial ECMO was given for the management of refractory hypoxemia that developed 14 days after the initiation of mechanical ventilation. The duration of ECMO support was 4 weeks, and she was successfully weaned off ECMO and mechanical ventilation.

Bronchobiliary fistula is a rare disorder consisting of an abnormal communication between the bronchial tree and the biliary duct. In Western countries, trauma, postoperative biliary stenosis, and biliary lithiasis are the predominant causative factors of bronchobiliary fistula. Bilioptysis (bile stained sputum) is a pathognomic finding for bronchobiliary fistula. To date, there are just a few reported cases of bronchobiliary fistula after sclerosis of a liver cyst. We describe the case of a 74-year-old woman who developed bronchobiliary fistula after sclerosing therapy of a liver cyst. The diagnosis was confirmed by the presence of bilioptysis and the chest and dynamic liver CT findings. The patient was successfully treated with antibiotics and percutaneous transhepatic catheter drainage.

The ulcerative colitis is a chronic inflammatory bowel disease with an unknown etiology. The major symptoms of ulcerative colitis are diarrhea, abdominal pain and hematochezia. However, arthritis, skin disorders, hepatobiliary inflammation and uveitis are occasionally recognized as systemic complications. Although there are few reports of coexistent pulmonary and inflammatory bowel disease, the lung is not generally considered to be a target organ in ulcerative colitis. We report a patient with ulcerative colitis-related bronchilolitis obliterans organizing pneumonia confirmed by video-assisted thoracoscopic surgery, who responded to corticosteroid therapy.

Nocardia farcinia, an aerobic, gram-positive bacilli actinomycetes of the genus Nocardia, is an uncommon pathogen found in humans. The most common Nocardia infection sites are the lung, central nervous system, and skin. Even though hematogenous dissemination can occur, isolation of the organism from blood cultures is very rare. We report a case of Nocardia infection that was isolated on blood cultures. A 59-year-old male with a medical history that includes a liver transplantation 6-years prior due to hepatocellular carcinoma secondary to chronic hepatitis B, developed pneumonia and was transferred to Severance Hospital. At the time of admission, the patient's initial exam showed hypothermia, tachypnea, and hypotension. His chest radiograph showed severe pneumonia and a large abscess on left upper lobe. Under the presumptive diagnosis of bacterial pneumonia or other opportunistic infection, we started broad spectrum antibiotics. However, he developed Nocardia sepsis, rapidly deteriorated, and subsequently died.

We report a case of Mycobacterium intracellulare pulmonary infection presenting as a solitary pulmonary nodule (SPN). A 35-year-old male was admitted due to a SPN in the right upper lobe which was detected on the chest radiography being examed due to recurrent cough for 1 year. The computed tomography (CT) revealed a spiculated nodule containing air-bronchogram, which was suspicious of malignancy. We performed transbronchial biopsy and the pathology showed granulomatous inflammation with caseous necrosis. Under the presumptive diagnosis of pulmonary tuberculosis, we started anti-tuberculous medication including isoniazid, rifampin, ethambutol, and pyrazinamide. In one month, however, the sputum culture was positive for Mycobacterium intracellulare. The follow-up chest CT showed slight aggravation of the previous lesions. Under the final diagnosis of Mycobacterium intracellulare pulmonary infection presenting as a solitary pulmonary nodule, we changed the regimen to rifampin, ethambutol, and clarithromycin. The follow-up chest CT after the completion of treatment, revealed resolution of the previous lesions.

Among the bronchogenic carcinomas, especially squamous cell carcinoma and large cell carcinoma frequently present with cavitation, which may result from tumor necrosis. Cavitary lesions of the tumor are occasionally associated with infection and misdiagnosed as benign lung abscess owing to the partial responsiveness to antibiotics. It is very difficult to distinguish the carcinomatous abscess from the benign lung abscess, because of their similar clinical and radiologic features. Delay in diagnosis of underlying lung cancer may result in poor outcome. Therefore, clinicians should remember that the patients with highly suspicious carcinoma of the lung should undergo further precise examinations to find out malignant cells.

The middle mediastinum contains several important organs and pluripotent cells. It is difficult to make a definitive diagnosis in patients with middle mediastinal tumors due to a wide range of diseases. The likelihood of malignancy is influenced primarily by the following factors: patient age, size, tumor location, and the presence or absence of symptoms. We describe a case of a middle mediastinal tumor, which was suspected on chest x-ray; chest computed tomography revealed the eccentric mass of distal esophagus. This case emphasizes the diagnostic importance of the chest x-ray to the physicians. The possible differential diagnoses are reviewed.

BACKGROUND: Pulmonary Langerhans cell histiocytosis (PLCH) is characterized by a proliferation of Langerhans cells and this results in granulomas that involve multiple organs of the body. Because the incidence of PLCH is very low in Korea and worldwide, collecting the clinical data of patients with PLCH nationwide is needed to determine the clinical features of Korean patients with PLCH. METHODS: The patients with PLCH confirmed by biopsy at any body site were included and the patients should have lung lesions present. A questionnaire that had items on the symptoms, lung function tests, the roentgenographic findings and the treatment was collected retrospectively at a Korean ILD Research Meeting. RESULTS: A total of 56 cases were collected. The number of males and females was 48 and 8, respectively, and their median age was 43 years (range: 18~67 years). The patients were current or ex-smokers in 79% of the cases. The most frequent symptom was coughing (39%), followed in decreasing order by dyspnea (38%), sputum (20%) and chest pain (20%). Pneumothorax was observed in 16 (29%) patients. Lung function tests showed a normal, restrictive, mixed or obstructive pattern in 26 (61%), 7 (16%), 7 (16%) and 3 patients (7%), respectively. Nodular-cystic lesion was most frequently observed in 59% of the patients on HRCT. The lung lesions were located in the middle and upper lobes in almost the cases. The median follow-up period was 90 months (range: 1~180 months) and only two patients died during this period. CONCLUSION: This study provides a national survey of the patients with PLCH during a long follow-up period.

Rifampin is one of the first line drugs for treating tuberculosis, but it might be associated with serious adverse effects, including renal failure. We report here on a case of a 57-year-old patient who developed Henoch-Shonlein purpura during antituberculosis therapy that included rifampin. The patient converted to negative on the AFB smear for tuberculosis two weeks after the initial administration of antituberculosis medication. After treatment for 60 days, this patient was diagnosed with Henoch-Shonlein purpura by the purpura lesion on the lower legs, the leukocytoclastic vasculitis, the renal impairment and the pathological examination. After stopping rifampin, the skin lesions disappeared in about 10 days and his renal function gradually improved. This case study showed that Henoch-Schonlein purpura can be caused by rifampin during antituberculosis therapy and we recommend that the use of rifampin should be restrained when clinical symptoms of Henoch-Shonlein purpura are observed.

Angiosarcoma is a rare but highly malignant tumorthat usually arises in the scalp or face of elderly males. Distant metastases favor the lung, liver, lymph nodes and skin. Metastatic pulmonary angiosarcoma commonly takes the form of a nodule but can sometimes appear as a thin-walled cyst. We report a case of 65 years-old male with a spontaneous pneumothorax, who underwent excision and radiotherapy for an angiosarcoma of the scalp 2 years ago. A chest CT scan revealed multiple cysts in the lung. The video-assisted thoracoscopic lung biopsy demonstrated subpleural cysts without tumor cells. A skin biopsy of the scalp showed an angiosarcoma. This case was diagnosed as a recurrence of an angiosarcoma with a supposed lung metastasis. This case suggests that a spontaneous pneumothorax in elderly people may be secondary to a pulmonary metastasis from an angiosarcoma of the scalp.

Lipoma is a common neoplasm in soft tissues. However, an intrapulmonary lipoma is a rare benign tumor. Patients with a bronchial lipoma might have a malignant potential related to their smoking history due to the case reports of lung cancer accompanied with lipoma. Endobronchial lipoma can cause irreversible parenchymal lung damage if not diagnosed and treated early. Therefore, it should initially be treated by fiberoptic bronchoscopy or surgery depending on the status of distal parenchymal lung damage. Bronchiolitis obliterans with organizing pneumonia (BOOP) is a pathological syndrome that is defined by the presence of buds of granulation tissue consisting of fibroblasts and collagen within the lumen of the distal air spaces. BOOP is caused by drug intoxication, connective tissue disease, infection, obstructive pneumonia, tumors, or an unknown etiology. We encountered a 58 year-old male patient with endobronchial lipoma, causing the collapse of the right middle and lower lobes, and BOOP due to obstructive pneumonia.
