RESUMO
PURPOSE: Bell palsy is an idiopathic peripheral facial nerve paralysis of sudden onset. Though the incidence in children is relatively lower than adult population, it is not uncommon. Because of its' relative rarity and good prognosis, there have been few studies about clinical features and courses of Bell palsy in pediatric population. The aim of our study was to report the clinical characteristics and practices of Bell palsy in children and adolescent in a single center. METHODS: We reviewed medical records of 70 patients diagnosed as Bell palsy in Daegu Catholic University Medical Center from September 2006 to June 2017 retrospectively. We included only first episode. RESULTS: Of the 70 patients, 35 was male, 35 was females. Median age was 102 months. There was no seasonal difference. Median duration of palsy was 3 days. The first symptoms were auricular pain (14%), facial palsy (83%), eye pain (1%), and dysguesia (1%). Preceding viral infection was present in 49% of patients. 26% of patients were treated with steroid alone, and 74% of cases were treated with steroid plus acyclovir. Oriental medicine was accompanied in 14% of patients. Among 49 patients who were followed over 4 weeks, 44(90%) had complete recovery. The recovery rates were 68% (4 weeks), 91% (3months), and 100% (10 months). Recurrent rate was 4%. CONCLUSION: The prognosis of Bell palsy in pediatric population was good, and recovery rates were 68% within 4 weeks, and 100% by 10 months after palsy onset.

Guillain-Barré syndrome (GBS) is characterized by ascending symmetric paralysis, paresthesia, and autonomic dysfunction. Autonomic dysfunctions develop in two-thirds of the patients, and urinary retention and paralytic ileus usually develop in severe and advanced cases. There has been no pediatric case with paralytic ileus as a presenting symptom of GBS. Reported herein is a case of GBS presenting vomiting as an initial symptom. A 28-month-old girl was brought to the emergency room due to a 2-day history of vomiting. She vomited multiple times 1 day before the visit, and had only single voiding on admission day. Her abdomen was distended, with decreased bowel sound. Intravenous fluid was given under the diagnosis with acute gastroenteritis with dehydration. The abdominal computed tomography revealed severe paralytic ileus and urinary bladder distention. After having two seizures, she developed respiratory failure necessitating ventilator care. On day 8 after admission, motor weakness with areflexia was noticed. The cerebrospinal fluid analysis showed elevated proteins (80 mg/dL) with no white blood cells (0/mm³). The nerve conduction study showed axonal-type peripheral polyneuropathy. GBS was diagnosed. During the follow-up, the patient was found to have motor weakness in the lower extremities. Paralytic ileus with protracted vomiting can be an initial presentation of GBS in children. Autonomic dysfunction with GBS can be considered in a differential diagnosis in vomiting patients with unclear etiologies.

Pseudoparalysis is defined as immobility of the extremity due to painful limb infection. However, such conditions may be misdiagnosed as nerve palsy when abnormal neurologic findings are present. We report herein a case with femoral osteomyelitis that was misdiagnosed as lumbosacral plexitis. A 7-month-old male infant was brought by his parents to the clinic who noticed that he did not move his left leg since 4 days prior to admission. Four days prior to admission, the parents noticed that he was not moving his left leg. There were no signs of inflammation in the involved limb. The left leg showed a motor weakness with grade 4/5, and it was hypotonic with decreased deep tendon reflexes. No abnormal findings were shown in studies which included lumbar spine magnetic resonance imaging (MRI), abdominal computed tomography (CT), and nerve conduction studies. Lumbosacral plexitis was diagnosed presumptively and intravenous immunoglobulin (IVIG) was given. The patient's symptom did not improve with the IVIG. After the orthopedic consultation, a hip MRI was performed and it showed acute osteomyelitis involving the proximal metaphysis of the left femur. Surgical debridement and intravenous antibiotics were administered. The patient's symptoms improved with treatment and he was fully recovered by the time of discharge. During the 4-year follow-up, the patient is doing well without any complication in the bone growth. During infancy, limb infection may present with nerve palsy that is characterized by hypotonic weakness with hyporeflexia. Pseudoparalysis may be the sole sign of osteomyelitis. In a unilateral limb weakness, musculoskeletal infection should be an initial diagnosis of exclusion with a thorough evaluation.

PURPOSE: Urinary tract infection (UTI) is the most common serious bacterial infection in infants younger than 3 months of age. Lumbar puncture is routinely performed to evaluate febrile young infants for sepsis. However, there is no clear consensus on the use of routine lumbar puncture to diagnose concomitant meningitis in infants with UTI. We evaluated the prevalence of coexisting bacterial meningitis and sterile cerebrospinal fluid (CSF) pleocytosis in young infants with UTI. METHODS: We retrospectively reviewed the medical records of 85 infants with UTI, aged from 29 to 99 days, who were admitted to Daegu Catholic University Medical Center from January 2013 to May 2016. We included 80 patients who had undergone lumbar puncture. Demographic features, clinical features, and laboratory findings were analyzed. Patients were divided into two groups based on the presence of sterile CSF pleocytosis and we compared these groups and assessed the differences between them. RESULTS: Of the 80 UTI patients enrolled, 34 (43%) had sterile CSF pleocytosis. None had bacterial meningitis, and CSF polymerase chain reaction for enterovirus was positive in two patients without CSF pleocytosis. There were no significant differences between the two groups with regards to age, body temperature, peripheral white blood cell count, urinalysis, and duration of hospital stay. CONCLUSIONS: Though sterile CSF pleocytosis is common in young UTI patients, coexisting bacterial or viral meningitis is very rare. Indications for lumbar puncture in these patients depend on clinical condition.

PURPOSE: This study was done to define clinical characteristics of fever without localizing signs (FWLS) in infants younger than 100 days of age with a goal of providing baseline data to establish a new diagnostic paradigm in the future. METHODS: We reviewed medical records of 183 patients who admitted to Daegu Catholic University Medical Center for FWLS younger than 100 days of age from January 2013 to September 2015 retrospectively. Demographic, clinical features and laboratory findings were analyzed. Patients were divided into serious bacterial infection (SBI) and non-SBI groups, and then were compared between two groups to find risk factors for SBI. RESULTS: Among 183 patients, lumbar puncture was performed in 98.9% and CSF pleocytosis was present in 35.9%. Sterile CSF pleocytosis was found in 43% of urinary tract infection (UTI) patients. None had concomitant bacterial meningitis in patients with UTI. As final diagnosis, febrile syndrome without source (25.7%) was most common. Among SBI, UTI was most common (99%). Birth weight, ESR, and CRP were significantly higher in SBI group compared to non-SBI group. Male sex (OR 4.93, 95% CI 1.60-15.24) and pyuria (OR 18.88, 95% CI 6.76-52.76) were identified as risk factors for SBI. Presence of sibling (OR 0.30, 95% CI 0.11-0.83) was significantly lower in SBI group. CONCLUSIONS: Our results showed UTI was the most common SBI in young infants with FWLS. Though aseptic meningitis can be coexisting with UTI, lumbar puncture may not be necessary in all patients having UTI.

PURPOSE: Respiratory syncytial virus (RSV) is known to induce Th2 immune response with increased IgE production. We investigated serum IgE levels in RSV bronchiolitis/pneumonia (RSV-LRI) in relation to disease severity. METHODS: One hundred seven children admitted with RSV-LRI were enrolled. The patients were divided into 2 groups according to serum IgE levels: the high IgE (n=39, more than 2 standard deviations from the mean levels for age-matched controls) and low IgE groups (n=68). We investigated if there were any differences in clinical and laboratory findings, and recurrence of wheezing between the 2 groups. The difference in IgE levels between severe (severity score≥3) and nonsevere groups was also studied. RESULTS: More frequent and prolonged fever was observed in the high IgE group than in the low IgE group (P<0.05). Patients showing severe symptoms or respiratory difficulties were more frequently seen in the high IgE group (P=0.01). There was no difference in parental allergy and atopic sensitization. The nearly same findings were observed in reanalysis of data from patients with the first RSV-LRI, but recurrence of wheezing was significantly higher in the high IgE group than in the low IgE group (P=0.04). Patients with high IgE levels were more frequently seen in severe patients than in nonsevere patients (P=0.01). CONCLUSION: Our study showed that children who presented with high serum IgE levels during RSV infections had more severe symptoms compared to those with low IgE levels. It suggests that measurement of total serum IgE levels might be helpful in evaluating disease severity and recurrent wheezing in children admitted with RSV-LRI.

PURPOSE: Vascular endothelial growth factor (VEGF), transforming growth factor beta1 (TGF-beta1), and platelet derived growth factor (PDGF) are known to be involved in the pathogenesis of inflammation and remodeling in asthmatic airways. YKL-40, a chitinase-like protein, and clusterin have been reported to be biomarkers for severe asthma. We examined the serum levels of growth factors, YKL-40, and clusterin in children with acute asthma or stable asthma, and investigated their correlation with clinical findings and lung function parameters. METHODS: Forty-one children (> or =6 years of age) with asthma were enrolled, and 2 groups were defined: 23 patients admitted with acute asthma (acute asthma group) and 18 patients with stable asthma (stable asthma group). The serum levels of VEGF, TGF-beta1, PDGF-BB, YKL-40, and clusterin were measured using enzyme-linked immunosorbent assay and assessed in relation to clinical manifestations and spirometric parameters. Fifteen age-matched controls were also studied. RESULTS: The serum levels of VEGF, TGF-beta1, and YKL-40 were significantly elevated in children with acute asthma compared to controls. The serum levels of VEGF and YKL-40 were higher in the stable asthma group than in controls. The serum levels of VEGF, TGF-beta1, and YKL-40 were not different between the acute asthma and stable asthma groups. The serum VEGF levels in the acute asthma group correlated significantly with asthma severity. The serum TGF-beta1 levels in stable asthma group showed a significant inverse correlation with (FEV1) forced expiratory volume in one second and FEF(25%-75%) (forced expiratory flow between 25 and 75 percent of expired vital capacity). Serum YKL-40 had no significant relationship with clinical manifestations and spirometric parameters. CONCLUSION: Our study suggests that increased serum levels of VEGF and YKL-40 might affect asthmatic airways not only during acute exacerbation but also in stable state and that serum TGF-beta1 might be a biomarker for airway obstruction in children with asthma.

PURPOSE: Complex febrile seizures are known for a risk factor for developing later epilepsy and also clinical indication for lumbar puncture to exclude central nervous system (CNS) infections. The purpose of this study is to investigate clinical characteristics of first complex febrile seizures and clinical usefulness of lumbar puncture for these patients to diagnose CNS infections. METHODS: A retrospective review was performed for patients aged 3 months to 5 years who evaluated for their first complex febrile seizures between September 2006 and June 2011. RESULTS: 121 patients (22.2%) were complex type among 545 cases with febrile seizures. 43 patients (35.5%) had a previous history of simple febrile seizure, 34 cases (28.1%) had a family history. Multiple seizures were the most common subtypes of complex features (74.4%). Lumbar punctures were performed in 42 patients (34.7%). The patient's median CSF(cerebrospinal fluid) white blood cell count was 2.0+/-2.5/microL (range 0-10), and 5 patients(12.5%) had CSF pleocytosis. The causes of fever were as follows: acute pharyngotonsillitis (55.4%), pneumonia (14.9%), exanthem subitum (13.2%), mycoplasma infection (3.3%), influenza (1.7%), urinary tract infection (0.8%), gastroenteritis (0.8%), and unknown (9.9%). There were 3 patients (2.5%) with final diagnosis as encephalopathy, aseptic encephalitis; all of three cases had persistent decreased mentality. During the follow up duration (mean, 31.4+/-14.3 months), one patient(0.8%) developed epilepsy. CONCLUSION: The presence of abnormal neurologic signs is highly suggestive of underlying CNS pathology in patients with complex febrile seizures, and an important indication for lumbar puncture for these patients.

PURPOSE: Collectin family is an important component of innate immunity, of which surfactant protein (SP)-D and mannose-binding lectin (MBL) are the most characterized. We examined SP-D and MBL in young children with acute respiratory syncytial virus (RSV) bronchiolitis. METHODS: Sixty-three children (7 days of hospital stay. All children were evaluated if they had recurrent wheezing during follow-up. SP-D and MBL were measured using enzyme-linked immunosorbent assay in serum collected on admission and compared with controls. Their levels were evaluated in relation to the symptom severity during admission and recurrence of wheezing after discharge. RESULTS: Serum SP-D increased significantly in the patients (P<0.01), but MBL showed no difference compared to the controls. SP-D levels were significantly higher in severe group compared with nonsevere group (P<0.05). SP-D levels in the patients with recurrent wheezing after discharge were significantly higher than in those without (P<0.05). MBL showed no difference in relation to the symptom severity or recurrence of wheezing. CONCLUSION: Our study showed that serum SP-D was associated with the severity of RSV bronchiolitis and suggests that it might be a biomarker of lung injury and recurrence of wheezing illnesses in the young children admitted with their first RSV bronchiolitis.

PURPOSE: Soluble ST2 (sST2) has been reported to regulate Th2 response. In this study, serum levels of sST2 and other cytokines were measured in recurrent early wheezers and asthmatic children. We aimed to investigate if there are any differences or similarities in Th1 or Th2 response between those two patient groups. METHODS: Fifty-nine patients admitted with exacerbation of wheezing or asthma were enrolled. Two patient groups were defined: children with atopic asthma (> or =6 years, n=21) and recurrent early wheezers (< or =2 years, n=38). Recurrent early wheezers were divided based on their atopic status: 19 were atopic and 19 were nonatopic. sST2, interleukin (IL) 33, IL-5, and interferon (IFN)-gamma were measured in serum samples collected on admission. Cytokine levels in both patient groups were compared with their age-matched controls and evaluated the relationship with blood eosinophils, serum IgE levels, and also with the severity of symptom. RESULTS: sST2 and IL-5 were significantly increased both in asthmatic children (P=0.02, P=0.004) and recurrent early wheezers (P=0.01, P=0.001) compared to their age-matched controls. IL-5 was significantly higher in atopic wheezers compared with non-atopic wheezers (P=0.04). Severity score showed a positive correlation with sST2 and IFN-gamma in asthmatic children, but only with IFN-gamma in early wheezers. There was an inverse correlation between sST2 and blood eosinophil counts both in asthmatic children and atopic recurrent wheezers. CONCLUSION: Our study suggests that sST2 might regulate allergic inflammation by suppressing eosinophilia and play an important role in pathophysiology of acute exacerbation of wheezing or asthma both in asthmatic children and early wheezers.

Acute external ophthalmoplegia, areflexia, and ataxia compose the classic Miller-Fisher syndrome (MFS). Pupillary dysfunction is present in half of patients with MFS. However, isolated internal ophthalmoplegia is rare in children with MFS. We report a case with MFS presenting with isolated internal ophthalmoplegia following an acute Epstein-Barr virus (EBV) infection. An 11-year-old girl with flu-like symptoms was diagnosed with having an acute EBV infection on prior admission. After discharge, she complained of anorexia, poor oral intake and dizziness associated with blurred vision when in the upright position. Physical examination on readmission 10 days later showed anisocoric, mydriatic pupils with an abnormal light reflex. The patient displayed no external ophthalmoplegia, ataxia or areflexia. Cerebrospinal fluid analysis showed elevated protein with no white blood cells. Serum anti-GQ1b antibody was negative. MFS was diagnosed under clinical findings and CSF albuminocytologic dissociation. Isolated internal ophthalmoplegia can be the sole manifestation of MFS. Therefore, MFS must be considered in the differential diagnosis for children presenting with unexplained acute internal ophthalmoplegia.

PURPOSE: Interleukin (IL)-33, a member of the IL-1 cytokine family, is considered to be important for innate-type mucosal immunity of the lung and also has been suggested to induce Th2-type immune responses. We aimed to investigate if IL-33 is involved in airway inflammation due to respiratory syncytial virus (RSV) infection in young children. METHODS: Thirty-eight infants ( or =2 of the following clinical findings: hypoxemia (7 days of hospital stay. The levels of IL-33 and the IL-33 receptor (sST2) were measured using enzyme-linked immunosorbent assay in nasal secretion samples collected from the patients on admission and compared with 20 age-matched controls. We also investigated the levels of IL-33 and sST2 in relation to the atopic status and symptom severity of the patients. RESULTS: Nasal IL-33 levels in the patients with acute RSV bronchiolitis were significantly increased (P<0.05), but sST2 showed no difference compared to the controls. Neither IL-33 nor sST2 showed significant difference in relation to the atopic status or severity of symptoms. CONCLUSION: Our study showed significantly increased IL-33 in the nasal secretions of the young infants admitted with acute RSV bronchiolitis and suggests that IL-33 is involved in the pathogenesis of RSV-induced airway inflammation.

PURPOSE: Bronchial asthma was reported to be an important risk factor of severe respiratory symptoms due to pandemic H1N1 influenza infection. In this study, we investigated if there was any difference in the clinical features of children with H1N1 pneumonia according to their atopic or asthma status. METHODS: Eighty-eight children admitted with pneumonia due to reverse transcriptase-polymerase chain reaction-confirmed H1N1 influenza infection during the period from September 2009 to January 2010 were enrolled. These patients were divided into atopic (n=42) and non-atopic (n=46) groups. The atopic group consisted of 23 asthmatic children and 19 non-asthmatic children with allergic rhinitis or atopic dermatitis. We retrospectively analyzed the medical records of the patients to investigate if there was any difference in the clinical features according to their atopic or asthma status. RESULTS: There was no age difference between atopic and non-atopic patients. Male preponderance was observed only in the atopic group.(P<0.05) The occurrence of wheezing, severity of respiratory symptoms, and number of emergency-room visits were significantly higher in atopic than non-atopic patients.(P<0.05) However, those variables showed no difference between asthmatic and non-asthmatic patients within the atopic group. Twelve patients in the atopic, non-asthmatic group were followed for 1 year after discharge, and 5 patients were diagnosed to have asthma with recurrence of wheezing and/or positive results to methacholine challenge tests. CONCLUSION: Our study shows that H1N1 influenza infection may cause more severe respiratory symptoms in atopic patients than in non-atopic patients, regardless of their asthma status. allergic rhinitis.(R=0.195, P=0.002). About 17% of the parents who care the allergic rhinitis children experienced the work absence due to their child's illness.

PURPOSE: In the present study, we investigated the clinical characteristics of tuberculosis in school-age children and adolescents, which is important as a reservoir for future disease burden. METHODS: Ninety patients, aged from 6 to 18 years, who were diagnosed and treated with tuberculosis during the period from January 2005 to July 2011, were enrolled. We retrospectively analyzed the medical records and investigated clinical characteristics of the patients. RESULTS: Eight patients were 6 to 12 (9%) and 82 were over 13 years of age (91%). There was a significantly higher percentage of males than females in the latter age group (P<0.01). Route of infection was not confirmed in 74 patients, and 16 patients were diagnosed through the school or military medical examinations with no clinical symptoms. Seventy patients (78%) were presented with pulmonary tuberculosis. Chronic persistent coughing was the most common presenting symptom, and both upper lobes were most frequently involved. Nineteen patients over 13 years of age had adult-type cavitary tuberculosis. The positive results for acid-fast smears or cultures were not high, and the rate of positive tuberculin skin test was 88%. The most frequent adverse effects of anti-tuberculosis treatment were hepatotoxicity, hyperuricemia, and gastrointestinal disorders. The duration of the treatment was much prolonged in 8 patients who had drug-resistant tuberculosis. CONCLUSION: Our study showed that pulmonary tuberculosis should be suspected in the adolescents who have prolonged respiratory symptoms. It also indicates that pulmonary tuberculosis in adolescents has similar characteristics to tuberculosis in adults, which suggests the potential important role of adolescent tuberculosis in community disease transmission.

We present the case of a patient with Epstein-Barr virus (EBV) encephalitis who developed abnormal white matter lesions during the chronic phases of the infection. A 2-year-old-boy was admitted for a 2 day history of decreased activity with ataxic gait. The results of the physical examination were unremarkable except for generalized lethargy and enlarged tonsils with exudates. Brain magnetic resonance imaging (MRI) at admission showed multiple high signal intensities in both basal ganglia and thalami. The result of EBV polymerase chain reaction (PCR) of the cerebral spinal fluid was positive, and a serological test showed acute EBV infection. The patient was diagnosed with EBV encephalitis and recovered fully without any residual neurologic complications. Subsequently, follow-up MRI at 5 weeks revealed extensive periventricular white matter lesions. Since the patient remained clinically stable and asymptomatic during the follow-up period, no additional studies were performed and no additional treatments were provided. At the 1-year follow-up, cranial MRI showed complete disappearance of the abnormal high signal intensities previously seen in the white matter. The patient continued to remain healthy with no focal neurologic deficits on examination. This is the first case of asymptomatic self-limited white matter lesions seen in serial MRI studies in a Korean boy with EBV encephalitis.

Non-typhoidal salmonella (NTS) is a common pathogen involved in food poisoning. It has various extraintestinal complications including encephalopathy. However, NTS associated encephalopathy is rarely reported. A previously healthy 14-year-old boy was admitted for altered level of consciousness. He had profuse watery diarrhea with fever on the day of admission. Physical examination was unremarkable except slightly increased bowel sounds and altered mental state. Cerebrospinal fluid analysis revealed mild pleocytosis. Meningoencephalitis was the presumptive diagnosis. His consciousness was recovered over 24 hours, bloody and mucoid diarrhea developed the next day after admission. NTS organism was isolated from his stool. After 1 week, he fully recovered neurologically but a mild watery diarrhea persisted at the time of discharge.

PURPOSE: Bronchiolitis obliterans (BO), an uncommon chronic obstructive lung disease in children, is most often seen following a severe lower respiratory tract infection (LRTI). We investigated the clinical characteristics, etiology, possible risk factors, radiological findings, and response to treatment in children diagnosed with post-infectious BO. METHODS: A retrospective study was performed on 62 patients diagnosed with post-infectious BO based on clinical and high-resolution computed tomography (HRCT) findings from 2005 to 2010. Forty-eight age-matched children who were admitted with the first episode of LRTI and did not subsequently develop BO were also studied as control subjects. RESULTS: Median ages at diagnosis and initial insult were 28 and 17 months, respectively. The median duration from initial LRTI until diagnosis was 5 months. Children who developed BO showed more respiratory compromise during their acute episodes of LRTI than those who did not. Symptom severity score decreased significantly after adequate treatment, which was significantly greater in patients treated with pulse steroid therapy than those treated with other controllers. CONCLUSION: The results suggest that the development of post-infectious BO should be suspected in the children showing persistent respiratory symptoms after severe LRTIs. They also suggest that adequate treatment including pulse steroid therapy may improve clinical status and the prognosis of these patients.

Transient magnetic resonance (MR) signal changes in the splenium of the corpus callosum (SCC) arise from many different conditions, including encephalopathy or encephalitis caused by infection, seizures, metabolic derangements, and asphyxia. Few case reports exist on reversible SCC lesions associated with rotavirus infection. A benign convulsion with mild gastroenteritis (CwG) is frequently associated with rotaviral infections. This entity is characterized by normal laboratory findings, electroencephalogram, neuroimaging, and good prognosis. We report a case of a 2.5-year-old Korean girl with rotavirus-associated CwG demonstrating a reversible SCC lesion on diffusion-weighted MR images. She developed 2 episodes of brief generalized tonic-clonic seizure with mild acute gastroenteritis without any other neurologic abnormality. Stool test for rotavirus antigen was positive. Brain MRI done on the day of admission showed a linear high signal intensity and decreased apparent diffusion coefficient values on the SCC. The lesion completely disappeared on follow-up MRI 6 days later. The patient fully recovered without any sequelae.

PURPOSE: Mycoplasma pneumoniae is a common causative agent of community acquired pneumonia in children and is well known to cause various respiratory and extrapulmonary diseases. We determined whether growth factors, including transforming growth factor (TGF)-beta1 and platelet-derived growth factor (PDGF-BB) that regulate airway fibrosis and remodeling, are increased in young children with M. pneumoniae pneumonia and also investigated if there was any difference in relation to the clinical status of the patients. METHODS: Fifty-two patients (3 to 6 years of age) who were admitted with M. pneumoniae pneumonia were enrolled and divided into 2 groups: the patients with frequent wheezing episodes (group A, n=28) and the patients with no previous history of wheeze (group B, n=24). The former group included the patients who had recurrent wheeze more than 3 times before admission. Fifteen children admitted with minor surgical problems were also studied as controls. TGF-beta1 and PDGF-BB were measured in the plasma samples collected on admission using ELISA in both patient groups and controls. RESULTS: Plasma TGF-beta1 and PDGF-BB levels were increased significantly in the patients with M. pneumoniae pneumonia as compared to the controls (P<0.01, respectively). TGF-beta1 and PDGF-BB were higher in group A than in group B, but the difference was not statistically significant (P=0.08 vs. P=0.05). In group A, TGF-beta1 was significantly higher in atopic patients than in non-atopic patients (P<0.05). CONCLUSION: Our study showed significantly increased TGF-beta1 and PDGF-BB in patients with M. pneumoniae pneumonia. It is suggested that these growth factors may play an important role in the pathogenesis of lower airway infection by M. pneumoniae.
