RESUMEN
“Poland’s syndrome” is a rare congenital disease whereby defects can accompany the chest, nipple, chest wall, and extremities on one side of the body. We diagnosed a 19-year-old male patient who presented to another hospital for a routine physical exam before enlisting in the military and was suspected of having a left brachial plexus injury. His chief complaint was the flatness of the left anterior chest wall without any significant functional inconvenience. Aplasia of the pectoralis minor and costosternal portion of the pectoralis major was observed through physical examination and computed tomography (CT). The patient was diagnosed with left-sided Poland’s syndrome without any limb abnormalities. Poland Syndrome should be highly considered in patients presenting with bilateral chest wall imbalance in the absence of with a recent traumatic history.
RESUMEN
BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) infection is a severe and life-threatening disease in patients with community-onset (CO) pneumonia. However, the current guidelines lack specificity for a screening test for MRSA infection. METHODS: This study was retrospectively conducted in elderly patients aged ≥65 years, who had contracted CO-pneumonia during hospitalization at the Jeju National University Hospital, between January 2012 and December 2014. We analyzed the risk factors of MRSA in these patients and developed a scoring system to predict MRSA infection. RESULTS: A total of 762 patients were enrolled in this study, including 19 (2.4%) with MRSA infection. Healthcare-associated pneumonia (HCAP) showed more frequent MRSA infection compared to community-acquired pneumonia (4.4% vs. 1.5%, respectively; p=0.016). In a multivariate logistic regression analysis, admissions during the influenza season (odds ratio [OR], 2.896; 95% confidence interval [CI], 1.022–8.202; p=0.045), chronic kidney disease (OR, 3.555; 95% CI, 1.157–10.926; p=0.027), and intensive care unit admission (OR, 3.385; 95% CI, 1.035–11.075; p=0.044) were identified as predictive factors for MRSA infection. However, the presence of HCAP was not significantly associated with MRSA infection (OR, 1.991; 95% CI, 0.720–5.505; p=0.185). The scoring system consisted of three variables based on the multivariate analysis, and showed moderately accurate diagnostic prediction (area under curve, 0.790; 95% CI, 0.680–0.899; p<0.001). CONCLUSION: MRSA infection would be considered in elderly CO-pneumonia patients, with three risk factors identified herein. When managing elderly patients with pneumonia, clinicians might keep in mind that these risk factors are associated with MRSA infection, which may help in selecting appropriate antibiotics.

OBJECTIVE: To develop and test the validity and reliability of a new instrument for measuring the thigh-foot angle (TFA) for the patients with in-toeing and out-toeing gait. METHODS: The new instrument (Thigh-Foot Supporter [TFS]) was developed by measuring the TFA during regular examination of the tibial torsional status. The study included 40 children who presented with in-toeing and out-toeing gaits. We took a picture of each case to measure photographic-TFA (P-TFA) in the proper position and to establish a criterion. Study participants were examined by three independent physicians (A, B, and C) who had one, three and ten years of experience in the field, respectively. Each examiner conducted a separate classical physical examination (CPE) of every participant using a gait goniometer followed by a TFA assessment of each pediatric patient with or without the TFS. Thirty minutes later, repeated in the same way was measured. RESULTS: Less experienced examiner A showed significant differences between the TFA values depending on whether TFS used (left p=0.003 and right p=0.008). However, experienced examiners B and C did not show significant differences. Using TFS, less experienced examiner A showed a high validity and all examiner's inter-test and the inter-personal reliabilities increased. CONCLUSION: TFS may increase validity and reliability in measuring tibial torsion in patients who has a rotational problem in lower extremities. It would be more useful in less experienced examiners.

Adding either macrolide or fluoroquinolone (FQ) to β-lactam has been recommended for patients with severe community-acquired pneumonia (CAP). However, due to the limited evidence available, there is a question as to the superiority of the two combination therapies. The MEDLINE, EMBASE, Cochrane Central Register, Scopus, and Web of Science databases were searched for systematic review and meta-analysis. A total of eight trials were analyzed. The total number of patients in the β-lactam plus macrolide (BL-M) and β-lactam plus fluoroquinolone (BL-F) groups was 2,273 and 1,600, respectively. Overall mortality of the BL-M group was lower than that of the BL-F group (19.4% vs. 26.8%), which showed statistical significance (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.49 to 0.94; P = 0.02). Length of hospital stay was reduced in the BL-M group compared to the BL-F group (mean difference, −3.05 days; 95% CI, −6.01 to −0.09; P = 0.04). However, there was no significant difference in length of intensive care unit (ICU) stay between the two groups. Among patients with severe CAP, BL-M therapy may better reduce overall mortality and length of hospital stay than BL-F therapy. However, we could not elicit strong conclusions from the available trials due to high risk of bias and methodological limitations.

Plasmacytomas are extramedullary accumulations of plasma cells originating from soft tissue. Mediastinal plasmacytoma is a rare presentation. A 67-year-old man recovered after antibiotic treatment for community-acquired pneumonia. However, on convalescent chest radiography after 3 months, mass like lesion at the right lower lung field was newly detected. Follow-up chest computed tomography (CT) revealed an increase in the extent of the right posterior mediastinal mass that we had considered to be pneumonic consolidations on previous CT scans. Through percutaneous needle biopsy, we diagnosed IgG kappa type extramedullary plasmacytoma of the posterior mediastinum.

A 37-year-old man with a right transfemoral amputation suffered from severe phantom limb pain (PLP). After targeting the affected supplementary motor complex (SMC) or primary motor cortex (PMC) using a neuro-navigation system with 800 stimuli of 1 Hz repetitive transcranial magnetic stimulation (rTMS) at 85% of resting motor threshold, the 1 Hz rTMS over SMC dramatically reduced his visual analog scale (VAS) of PLP from 7 to 0. However, the 1 Hz rTMS over PMC failed to reduce pain. To our knowledge, this is the first case report of a successfully treated severe PLP with a low frequency rTMS over SMC in affected hemisphere.

Pneumothorax is an extremely rare complication of non-tuberculous mycobacterial infection. A 52-year-old man presenting with difficulty breathing and chest pain was admitted to our hospital. A right-sided pneumothorax was observed on chest radiography and chest computed tomography showed multiple cavitating and non-cavitating nodules with consolidation in the upper to middle lung zones bilaterally. Serial sputum cultures were positive for Mycobacterium kansasii, and he was diagnosed with pulmonary M. kansasii disease complicated by tension pneumothorax. After initiation of treatment including decortications and pleurodesis, the patient made a full recovery. We herein describe this patient's course in detail and review the current relevant literature.

BACKGROUND/AIMS: Nursing home-acquired pneumonia (NHAP) is included under healthcare-associated pneumonia. However, the optimal treatment strategy for NHAP has been controversial in several studies. We evaluated the clinical features of NHAP compared to community-acquired pneumonia (CAP) in elderly patients admitted with pneumonia. METHODS: This was a retrospective study in elderly patients aged > or = 65 years with NHAP or CAP who were hospitalized at Jeju National University Hospital between January 2012 and April 2013. RESULTS: A total of 209 patients were enrolled, and 58 (27.7%) had NHAP. The patients with NHAP were older, had more frequent central nervous system disorders, and showed worse clinical parameters. Potential drug-resistant pathogens were more frequently detected in the NHAP group (22.4% vs. 9.9%, p = 0.018), and the incidences of Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus were 8.6% and 10.3%, respectively. In-hospital mortality occurred in 13 patients (22.4%) with NHAP and 17 patients (11.2%) with CAP (p = 0.039). In multivariate analyses, only higher pneumonia severity index (PSI) score was associated with increased mortality (p < 0.001), and the PSI score was higher in the NHAP group than that in the CAP group. CONCLUSIONS: Elderly patients admitted with NHAP showed more severe pneumonia at onset, higher rates of potentially drug-resistant pathogens, and worse clinical outcomes than those with CAP. However, higher in-hospital mortality in those with NHAP seemed to be related to the PSI score reflecting host factors and severity of pneumonia rather than the type of pneumonia or the presence of drug-resistant pathogens.

BACKGROUND: Mycobacterial identification in active pulmonary tuberculosis (APTB) is confirmative, even though successful rates using self-expectorated sputum are limited. Sputum specimens collected by hypertonic saline nebulization showed higher bacteriologic diagnostic sensitivities over those of self-expectoration, mostly studied in smear-negative or sputum-scarce patients. The efficacy of induced sputum was rarely assessed in real clinical settings. METHODS: A prospective randomized case-control study was performed in one hospital. The subjects highly suspicious of APTB were asked to provide 3 pairs of sputum specimens in 3 consecutive days. The first pairs of the specimens were obtained either by self-expectoration (ES) from the next day of the visit or sputum induction with 7% saline nebulization in clinic (SI), and the other specimens were collected in the same way. The samples were tested in microscopy, culture, and polymerase chain reaction (PCR). The outcomes of the bacteriological diagnosis were compared. RESULTS: Seventy six patients were assigned to either ES (38 subjects, median age of 51, 65.8% male) or SI (38 subjects, median age of 55, 52.6% male). APTB was clinically confirmed in 51 patients (70.8%), 27 in ES and 24 in SI. Among the APTB, more adequate specimens were collected from SI (41/65, 63.1%) than ES (34/80, 42.5%) (p=0.01). Bacteriological confirmation was achieved in 14 (58.3%) patients in SI, and 13 (48.1%) in ES (p=0.46). In the same-day bacteriological diagnosis with microscopy and PCR, there were positive results for 9 patients (37.5%) in SI and 7 patients (25.9%) in ES (p=0.37). CONCLUSION: Sputum induction improves sputum specimen adequacy. It may be useful for the same-day bacteriological diagnosis with microscopic examination and PCR.

Churg-Strauss syndrome (CSS) is a rare systemic necrotizing vasculitis. Cranial nerve involvement is very rare in CSS. A 59-year-old woman had complained of both hearing impairments for eight months and left facial palsy for three months. Left facial and cochlear neuropathies were detected in electrodiagnostic studies. Paranasal sinus computed tomography (CT) showed chronic pansinusitis. Chest CT revealed eosinophilic infiltration in the right upper lobe. Tissue biopsy of the right inferior turbinate displayed necrotizing vasculitis with eosinophilic infiltration. She was diagnosed as CSS, based on the presence of eosinophilia, pulmonary infiltration, paranasal sinusitis, and biopsy containing blood vessels with extravascular eosinophils. She was treated with intravenous and oral steroids and azathioprine, showing relatively good prognosis on facial palsy and hearing impairment. We report a very rare case of CSS presented with hearing impairment and facial palsy.

BACKGROUND: The increasing number of outpatients with multidrug-resistant (MDR) pathogens has led to a new category of pneumonia, termed healthcare-associated pneumonia (HCAP). We determined the differences in etiology and outcomes between patients with HCAP and those with community-acquired pneumonia (CAP) to clarify the risk factors for HCAP mortality. METHODS: A retrospective study comparing patients with HCAP and CAP at Jeju National University Hospital. The primary outcome was 30-day mortality. RESULTS: A total of 483 patients (208 patients HCAP, 275 patients with CAP) were evaluated. Patients with HCAP were older than those with CAP (median, 74 years; interquartile range [IQR], 65-81 vs. median, 69 years; IQR, 52-78; p<0.0001). Streptococcus pneumoniae was the major pathogen in both groups, and MDR pathogens were isolated more frequently from patients with HCAP than with CAP (18.8% vs. 4.9%, p<0.0001). Initial pneumonia severity was greater in patients with HCAP than with CAP. The total 30-day mortality rate was 9.9% and was higher in patients with HCAP based on univariate analysis (16.3% vs. 5.1%; odds ratio (OR), 3.64; 95% confidence interval (CI), 1.90-6.99; p<0.0001). After adjusting for age, sex, comorbidities, and initial severity, the association between HCAP and 30-day mortality became non-significant (OR, 1.98; 95% CI, 0.94-4.18; p=0.167). CONCLUSION: HCAP was a common cause of hospital admissions and was associated with a high mortality rate. This increased mortality was related primarily to age and initial clinical vital signs, rather than combination antibiotic therapy or type of pneumonia.

Despite the advanced technologies of intensive care, massive hemoptysis can still cause death in a small subset of patients. Extracorporeal membrane oxygenation (ECMO) is expected to provide adequate gas exchange, to reduce ventilator-induced lung injuries, and to eventually improve outcomes in these patients. Also, the instability of vital signs due to hemoptysis makes it impossible to perform immediate interventional procedures such as embolization and resectional surgery. In these cases, ECMO may be instituted as a bridge therapy. Herein, we describe the detailed course of our case, with the hopes of helping physicians to decide when to initiate ECMO in patients with massive hemoptysis.

Tuberculosis of the stomach is extremely rare. We report the case of a 38-year-old woman who presented with epigastric discomfort and a palpable mass that persisted for a period of one month. We also report our findings from the abdominal computed tomographic, upper endoscopic and endoscopic ultrasonographic examinations of the patient. Abdominal computed tomography (CT) showed the presence of a large mass with an irregularly contoured low attenuation lesion. Upper endoscopy and endoscopic ultrasonography revealed a protruding ulcerative mass with an ill-defined heteroechoic subepithelial lesion originating from the gastric submucosal layer. This was previously misdiagnosed as a gastrointestinal stromal tumour. Endoscopic biopsy specimen was positive on acid-fast bacillus staining, and polymerase chain reaction for Mycobacterium tuberculosis was also positive. Abdominal CT and endoscopy at the patient's three-month follow-up showed near complete resolution of the lesion.

BACKGROUND/AIMS: Airway hyperresponsiveness (AHR) is one of the typical characteristics of asthma. However, its natural course is unknown. The presence of AHR is often not assessed in asthmatics undergoing medical treatment. We investigated the changes of AHR as compared with clinical parameters in patients with mild asthma. METHODS: We enrolled patients who were diagnosed with asthma, but were asymptomatic for > 3 months while undergoing medical treatment. AHR was measured using a methacholine bronchial provocation test after a 2-week washout period. AHR-negativity was defined as a PC20 > 25 mg/mL. Clinical parameters were retrospectively compared between the AHR-negative and -positive patients. RESULTS: Among 54 patients, 22 (40.7%) were AHR negative. Factors associated with the maintenance of AHR were male sex, presence of dyspnea, and high-dose inhaled corticosteroid plus long-acting beta agonists at initial presentation (respectively, p < 0.05). Age, symptoms other than dyspnea, blood tests, results of spirometry, diagnostic methods at presentation, and time from diagnosis to follow-up testing were not significantly different between AHR-negative and AHR-positive patients. Multivariate analyses failed to show a significant difference between the two groups, except for male sex (p = 0.014). CONCLUSIONS: Approximately 40% of patients with mild asthma show no AHR or clinical remission of the disease. Male sex may be a predictive factor for persistent AHR. However, altered AHR status is not predictable in patients with mild asthma undergoing medical treatment. Therefore, the cessation of regular controller might be advocated, and reassessment of AHR should be mandatory.

Mycobacterium szulgai is a rare nontuberculous mycobacterium found in Korea. It is an opportunistic pathogen and is usually isolated from patients with a history of alcoholism, chronic pulmonary disease, or an immunocompromising condition. We present here a case of M. szulgai isolated from a patient with a history of pulmonary tuberculosis. A 54-year-old man was admitted with dyspnea and febrile sensation. He had a history of pulmonary tuberculosis which occurred 30 years earlier and treatment with anti-tuberculosis medication. His chest computed tomography scan showed cavitary consolidation in both upper lungs. A sputum acid-fast bacilli (AFB) smear was positive and anti-tuberculous medication was started. However, a polymerase chain reaction for mycobacterium tuberculosis was negative and anti-tuberculous medication was stopped. M. szulgai was isolated on 3 separate sputum and bronchial wash fluid AFB cultures. He was treated with clarithromycin, rifampicin, and ethambutol. After 1 month, a sputum AFB smear and culture became negative and no additional M. szulgai were isolated during a 16-month treatment.

BACKGROUND: Pyrazinamide (PZA) is an effective antitubercular drug that becomes toxic to Mycobacterium tuberculosis when converted to pyrazinoic acid by pyrazinamidase (PZase), encoded by mycobacterial pncA. A strong association was noted between the loss of PZase activity and PZA resistance. The causative organisms in extrapulmonary tuberculosis are rarely cultured and isolated. To detect pncA mutations in specimens from extrapulmonary tuberculosis as confirmative diagnosis of mycobacterial infection and alternative susceptibility test to PZA. METHODS: Specimens were collected from clinically proven extrapulmonary tuberculosis. pncA was sequenced and compared with wild-type pncA. RESULTS: pncA from 30 specimens from 23 donors were successfully amplified (56.6% in specimens, 59% in donors). Six mutations in pncA were detected (20.0% in amplified specimens, 26.1% in specimen donors) at nucleotide positions of 169, 248 and 419. The mutation at position 169 results in substitution of aspartic acid for histidine, a possible allelic variation of M. bovis that have intrinsic PZA resistance. The mutation at position 248 changes proline into arginine and that at position 419, arginine into histidine. CONCLUSION: DNA-based diagnosis using pncA may be simultaneously useful for the early diagnosis of mycobacterial infection and the rapid susceptibility to PZA in extrapulmonary tuberculosis. A potential implication of pncA allelic variation at 169 might be suggested as a rapid diagnostic test for M. bovis infection or Bacille Calmette-Guerin (BCG) reactivation.

Ramsay Hunt syndrome associated with the Varicella zoster virus (VZV) infection is characterized by vesicles on the pinna, otalgia, facial nerve palsy and sensorineural hearing loss. Although significant complications from VZV infection are increasing, thrombosis associated with VZV infection is one of the rare complications in adults. The VZV itself could cause endothelial damage in the various organs. Subsequently, the thrombosis might be complicated. A previously healthy 84 year-old female patient was diagnosed with Ramsay Hunt syndrome. On the 7th day of antiviral treatment, she complained of sudden breathlessness. She was hypoxemic with an elevated alveolar-arterial oxygen difference and needed to be supported by mechanical ventilation. Massive pulmonary thrombosis was documented by computerized tomography and she successfully underwent thrombolytic therapy. We report a case of massive pulmonary thromboembolism associated with VZV infection, treated with thrombolytic therapy.

BACKGROUND: To evaluate chest CT findings of pandemic influenza A/H1N1 pneumonia without co-infection. METHODS: Among 56 patients diagnosed with pandemic influenza A/H1N1 pneumonia, chest CT was obtained in 22 between October 2009 and Februrary 2010. Since two patients were co-infected with bacteria, the other twenty were evaluated. Predominant parenchymal patterns were categorized into consolidation, ground glass opacity (GGO), and mixed patterns. Distribution of parenchymal abnormalities was assessed. RESULTS: Median age was 46.5 years. The CURB-65 score, which is the scoring system for severity of community acquired pneumonia, had a median of 1. Median duration of symptoms was 3 days. All had abnormal chest x-ray findings. The median number of days after the hospital visit that Chest CT was performed was 1. The reasons for chest CT performance were radiographic findings unusual for pneumonia (n=13) and unexplained dyspnea (n=7). GGO was the most predominant pattern on CT (n=13, 65.0%). Parenchymal abnormalities were observed in both lungs in 13 cases and were more extensive in the lower lung zone than the upper. Central and peripheral distributions were identified in ten and nine cases, respectively. One showed diffuse distribution. Peribronchial wall thickening was found in 16 cases. Centrilobular branching nodules (n=7), interlobular septal thickening (n=4), atelectasis (n=1), pleural effusion (n=5), enlarged hilar and mediastinal lymph nodes (n=6 and n=7) were also noted. CONCLUSION: Patchy and bilateral GGO along bronchi with predominant involvement of lower lungs are the most common chest CT findings of pandemic influenza A/H1N1 pneumonia.

During the pandemic, few patients have suffered from severe pneumonia leading to acute respiratory distress syndrome (ARDS) and multiple organ dysfunction necessitating prolonged intensive care with higher mortality. Although sepsis and ARDS represent hypercoagulable states, acute pulmonary thromboembolism is rarely encountered in influenza infection. Fifty five year old female patient admitted with pneumonia associated with influenza A infection, progressed into ARDS. Pulmonary thromboembolism was detected by CT scan and treated with anticoagulants. This is the first case report of acute pulmonary thromboembolism in a patient with pandemic influenza (H1N1 2009) in Korea.

In photodynamic therapy, a chemical photosensitizer is activated by light of a specific wavelength., Photodynamic therapy has been combined with bronchoscopy in patients who are ineligible for surgical resection in order to treat patients with early central lung cancer. Here, we describe 3 patients with early central lung cancer who were treated effectively using photodynamic therapy. Our experience shows that this approach is a useful modality in the therapy of these types of tumors.
