Particulate matter deposition and its impact on tuberculosis severity: A cross-sectional study in Taipei.

The objective of this study was to examine the association between the lung lobe-deposited dose of inhaled fine particulate matter (PM2.5) and chest X-ray abnormalities in different lung lobes of pulmonary tuberculosis (TB), multidrug-resistant tuberculosis (MDR-TB), and non-tuberculosis mycobacteria infections (NTM). A cross-sectional study was conducted between 2014 and 2022, comprising 1073 patients who were recruited from chest department clinic in a tertial refer hospital in Taipei City, Taiwan. Ambient 1-, 7-, and 30-day PM2.5 exposure and the deposition of PM2.5 in different lung lobes were estimated in each subject. The ß coefficient for PM2.5 and deposited PM2.5 in lungs with the outcome variables (pulmonary TB, MDR-TB, and NTM infection) was derived through regression analysis and adjusted for age, gender, BMI, smoking status, and family income. We observed that a 1 µg/m3 increase in ambient PM2.5 was associated with an increase of MDR-TB infections of 0.004 times (95%CI: 0.001-0.007). A 1 µg/m3 increase in 1-day and 7-day PM2.5 deposition in left upper lobe and left lower lobe was associated with an increase in chest X-ray abnormalities of 9.19 % and 1.18 % (95%CI: 0.87-17.51 and 95%CI: 0.08-2.28), and 4.52 % and 5.20 % (95%CI: 0.66-8.38 and 95%CI: 0.51-9.89) in left lung of TB patients, respectively. A 1 µg/m3 increase in 30-day PM2.5 deposition in alveolar region was associated with an increase in percent abnormality of 2.50 % (95%CI: 0.65-4.35) in left upper lobe and 3.33 % (95%CI: 0.65-6.01) in right middle lobe, while in total lung was 0.63 % (95%CI: 0.01-1.27) in right upper lobe and 0.37 % (95%CI, 0.06-0.81) in right lung of MDR-TB patients. Inhaled PM2.5 deposition in lungs was associated with an exacerbation of the radiographic severity of pulmonary TB, particularly in pulmonary MDR-TB patients in upper and middle lobes. Particulate air pollution may potentially exacerbate the radiographic severity and treatment resistance in individuals with pulmonary TB.

Different Impacts of Traffic-Related Air Pollution on Early-Onset and Late-Onset Asthma.

Background: Early-onset asthma (EOA) and late-onset asthma (LOA) are two distinct phenotypes. Air pollution has been associated with an increase in poorer asthma outcomes. The objective of this study was to examine the effects of traffic-related air pollution (TRAP) on asthma outcomes in EOA and LOA patients. Methods: A cross-sectional study was conducted on 675 asthma patients (LOA: 415) recruited from a major medical center in Taiwan. The land-use regression (LUR) model was used to estimate the level of exposure to PM10, PM2.5, NO2, and O3 on an individual level. We investigated the association between TRAP and asthma outcomes in EOA and LOA patients, stratified by allergic sensitization status, using a regression approach. Results: An increase in PM10 was associated with younger age of onset, increased asthma duration, and decreased lung function in EOA patients (p<0.05). An increase in PM10 was associated with older age of onset, and decreased asthma duration, eosinophil count, and Asthma Control Test (ACT) score in LOA patients. An increase in PM2.5 was associated with younger age of onset, increased asthma duration, decreased eosinophil count, and lung function in EOA patients (p<0.05). An increase in PM2.5 was associated with decreased lung function and ACT score in LOA patients. An increase in NO2 was associated with increased eosinophil count and decreased lung function in EOA patients (p<0.05). An increase in O3 was associated with decreased lung function in LOA patients (p<0.05). In addition, associations of TRAP with age of onset and eosinophil counts were mainly observed in both EOA and LOA patients with allergic sensitization, and an association with ACT was mainly observed in LOA patients without allergic sensitization. Conclusion: The impact of TRAP on age of onset, eosinophil count, and lung function in EOA patients, and ACT in LOA patients, was affected by the status of allergic sensitization.

Extreme temperatures increase the risk of pediatric pneumonia: a systematic review and meta-analysis.

Introduction: The impact of climate change on ambient temperatures threatens to worsen pediatric pneumonia-related outcomes considerably. This study examined the associations of temperature variation and extreme temperature with pediatric pneumonia-related events using a meta-analysis. Methods: We systematically searched PubMed, Medline, Embase, and Web of Science databases for relevant literature, and the quality of evidence was assessed. Fixed and random-effects meta-analyses were performed to calculate the pooled relative risks (RRs) of the associations with pneumonia-related events. Results: We observed that a 1°C temperature variation increased the RR of pneumonia events by 1.06-fold (95% confidence interval (CI): 1.03-1.10). A 1°C temperature variation increased the RR by 1.10-fold of the pediatric pneumonia hospital admissions (95% CI: 1.00-1.21) and 1.06-fold of the pediatric pneumonia emergency department visits (95% CI: 1.01-1.10). Extreme cold increased the RR by 1.25-fold of the pediatric pneumonia events (95% CI: 1.07-1.45). A 1°C temperature variation increased the RR of pneumonia events in children by 1.19-fold (95% CI: 1.08-1.32), girls by 1.03-fold (95% CI: 1.02-1.05), and in temperate climate zones by 1.07-fold (95% CI: 1.03-1.11). Moreover, an increase in extreme cold increased the RR of pneumonia events in children by 2.43-fold (95% CI: 1.72-3.43), girls by 1.96-fold (95% CI: 1.29-2.98) and in temperate climate zones by 2.76-fold (95% CI: 1.71-4.47). Conclusion: Our study demonstrated that pediatric pneumonia events are more prevalent among children, particularly girls, and individuals residing in temperate climate zones. Climate change represents an emergent public health threat, affecting pediatric pneumonia treatment and prevention.. Systematic Review Registration: PROSPERO (CRD42022378610).

Multiple mesenteric lymphadenopathies in pediatric with ulcerative colitis: A case report.

Ulcerative colitis (UC) is one of the 2 major disorders in pediatric inflammatory bowel disease (IBD). Differentiating IBD at an early stage remains difficult, and abdominal imaging and early precise investigations are crucial. A 2-year-old girl was referred to the emergency department after experiencing colicky abdominal pain for 1 month. She had bloody stool 4 days before admission with the frequency of about 1-2 times per day. She also experienced anorexia, nausea, and weight loss. From Abdominal CT-Scan with contrast, multiple mesenteric lymphadenopathies accompanied by liver enlargement and minimal ascites were found. A colonoscopy showed multiple ulcers in the rectum and sigmoid colon. The histology of the gastric and colon showed lymphocyte infiltration in lamina propria. Children with UC usually present with the classic symptoms of weight loss, abdominal pain, and bloody diarrhea. The UC patients could present also with nonclassic symptoms of poor growth, anemia, or extraintestinal manifestations. The presence of inflamed mesenteric lymph nodes in the inflammatory process in UC can be associated with peri-intestinal inflammatory reactions. Mesenteric lymphadenopathies can happen in UC and early investigations using colonoscopy and biopsy are important investigative procedures to evaluate patients with UC.

Extreme weather and asthma: a systematic review and meta-analysis.

BACKGROUND: Climate change's influence on extreme weather events poses a significant threat to the morbidity and mortality of asthma patients. The aim of this study was to examine associations between extreme weather events and asthma-related outcomes. METHODS: A systematic literature search for relevant studies was performed using the PubMed, EMBASE, Web of Science and ProQuest databases. Fixed-effects and random-effects models were applied to estimate the effects of extreme weather events on asthma-related outcomes. RESULTS: We observed that extreme weather events were associated with increasing risks of general asthma outcomes with relative risks of 1.18-fold for asthma events (95% CI 1.13-1.24), 1.10-fold for asthma symptoms (95% CI 1.03-1.18) and 1.09-fold for asthma diagnoses (95% CI 1.00-1.19). Extreme weather events were associated with increased risks of acute asthma exacerbation with risk ratios of asthma emergency department visits of 1.25-fold (95% CI 1.14-1.37), of asthma hospital admissions of 1.10-fold (95% CI 1.04-1.17), of asthma outpatient visits of 1.19-fold (95% CI 1.06-1.34) and of asthma mortality of 2.10-fold (95% CI 1.35-3.27). Additionally, an increase in extreme weather events increased risk ratios of asthma events by 1.19-fold in children and 1.29-fold in females (95% CI 1.08-1.32 and 95% CI 0.98-1.69, respectively). Thunderstorms increased the risk ratio of asthma events by 1.24-fold (95% CI 1.13-1.36). CONCLUSIONS: Our study showed that extreme weather events more prominently increased the risk of asthma morbidity and mortality in children and females. Climate change is a critical concern for asthma control.

Disseminated intravascular coagulation initial score as a predictor of mortality in children with dengue shock syndrome: A retrospective cohort study.

Background: The mortality of dengue shock syndrome (DSS) in children is still high at 12-44%. Assessment of DIC initial score using the International Society on Thrombosis and Haemostasis scoring system can help diagnosing and treating DIC, while also predicting mortality in pediatric patients with DSS. Methods: We retrospectively collected data of children with DSS at Dr. Sardjito Hospital between January 2017 and June 2021 with inclusion criteria such as age 1 month to 18 years and laboratory parameters taken within first 24 h after DSS workup. Results: Results showed a sample population consisting of 20 male subjects (58.8%), 24 aged >5 years (76.0%), 21 with good nutritional status (61.8%), and median length of stay 5 days (3-7), with saturation of 98% (97-99) and median pediatric Glasgow coma scale level of consciousness of 13. The laboratory profile showed median levels of hematocrit at 40.9% (32.9-44.9), thrombocytes at 20,500/L (14,000-32,000), prothrombin time of 17.8 s (14.9-25.3), fibrinogen at 123 mg/dL (106-184) and D-dimer at 832.5 ng/mL (362-1119). A DIC initial score of ≥5 25 (73.5%) resulted with a mortality of 9 children (36.0%) with a 92% survival rate in the first 6 h. The first 6-h survival according to each DIC score parameter showed 93.8%, 100%, 85.7%, and 94.1% of thrombocytes ≤50,000 µ/L, fibrinogen <100 mg/dL, D-dimer >1000 ng/mL, and prothrombin time >6 s, respectively. Conclusion: A DIC initial score ≥5 can be used as a mortality predictor in the first 6 h after DSS diagnosis.

Co-infection of SARS-CoV-2 with other viral respiratory pathogens in Yogyakarta, Indonesia: A cross-sectional study.

Background: Growing evidence shows that viral co-infection is found repeatedly in patients with Coronavirus Disease-2019 (COVID-19). This is the first report of SARS-CoV-2 co-infection with viral respiratory pathogens in Indonesia. Methods: Over a one month period of April to May 2020, SARS-CoV-2 positive nasopharyngeal swabs in our COVID-19 referral laboratory in Yogyakarta, Indonesia, were tested for viral respiratory pathogens by real-time, reverse transcription polymerase chain reaction (RT-PCR). Proportion of co-infection reported in percentage. Results: Fifty-nine samples were positive for other viral respiratory pathogens among a total of 125 samples. Influenza A virus was detected in 32 samples, Influenza B in 16 samples, Human metapneumovirus in 1 sample, and adenovirus in 10 samples. We did not detect any co-infection with respiratory syncytial virus. Nine (7.2%) patients had co-infection with more than two viruses. Conclusion: Viral co-infection with SARS-CoV-2 is common. These results will provide a helpful reference for diagnosis and clinical treatment of patients with COVID-19.

Lag time to diagnosis as a predictor of mortality in children with extraocular retinoblastoma: Experience from a developing country.

AIM: To define the prevalence of mortality and identify factors associated with mortality in pediatric patients with extraocular retinoblastoma attending the tertiary hospital in Indonesia. METHODS: We retrospectively collected medical records from 2013 to 2019 of patients who were diagnosed with extraocular retinoblastoma. Cox proportional hazard regression analysis with 95% confidence interval (CI) was used to evaluate the association of mortality predictors with patient outcomes (Hazard Ratio [HR], 95% CI) with significance set as p < .05. RESULTS: Overall, 60 patients were included in this study for a retrospective chart review, with 55% males and 45% females. The median age at diagnosis was 13 (5-24) months. About 60% of the patients did not survive, while 2-year survival probability was 45%. The overall median survival time was 21.5 (7.25-40.75) months. Predictors of mortality were laterality (unilateral/bilateral): HR 2.15 (95% CI: 1.07-4.28; p = .03), nutritional status: HR 2.65 (95% CI: 1.34-5.25; p = .05), and lag time to diagnosis: HR 3.12 (95% CI: 1.56-6.2; p = .001). CONCLUSION: Laterality, nutritional status and lag time to diagnosis were identified to be mortality predictors in extraocular retinoblastoma. The 2-year survival for children with extraocular retinoblastoma was 45% with 21 months for median survival.

Sepsis and disseminated intravascular coagulation are rare complications of typhoid fever: A case report.

INTRODUCTION: and importance: Typhoid fever is an infection caused by Salmonella typhi. The common complications are intestinal perforation and typhoid encephalopathy. Cases of typhoid fever with sepsis and/or disseminated intravascular coagulation (DIC) are rarely reported, even though typhoid fever is endemic in Indonesia. CASE PRESENTATION: A 4-year-old male referral case from a district hospital was experiencing fever, decrease of consciousness and massive bleeding from his gastrointestinal tract and nose. Investigation revealed results from the IgM typhoid test using Tubex®TF, with the score of +8. PELOD 2 score was 10, and PSOFA was 5. DIC score was 7. Based on these findings, the patient was diagnosed with typhoid fever, with DIC and sepsis being the complication of the typhoid fever. CLINICAL DISCUSSION: DIC is mostly a subclinical event, and severe bleeding complications found in typhoid fever are uncommon, although DIC scores which indicate an imbalance of coagulation and fibrinolysis are markedly elevated in patients with typhoid. DIC can be a part of multi-organ dysfunction due to sepsis syndrome. Acute infection can also result in systemic activation of coagulation. CONCLUSION: Sepsis and DIC are rare complications of typhoid fever. Typhoid fever can be presented with profound bleeding manifestation other than gastrointestinal bleeding, since it is a common symptom of typhoid fever. Further research should be conducted to postulate association between typhoid fever and DIC.

Neutrophil lymphocyte ratio as predictor of mortality in pediatric patients with bacterial meningitis: A retrospective cohort study.

BACKGROUND: Bacterial meningitis causes high mortality rates among children. Even with early diagnosis and prompt treatment, around 15% of patients die especially in the first and second days after diagnosis. The neutrophil lymphocyte ratio has been reported to be a predicting factor of severity and outcome for patients with pneumonia and sepsis. However, only a few studies are available to rate the neutrophil lymphocyte ratio as a predictor of mortality in bacterial meningitis. This study aimed to know the role of the neutrophil lymphocyte ratio as a predictor of mortality in patients with bacterial meningitis. METHODS: This retrospective study was conducted at Dr. Sardjito General Hospital, Yogyakarta, Indonesia between January 2016 to December 2020. Multivariate analysis was used to assess the correlation between predicting factors and outcomes using logistic regression analysis. RESULTS: A total of 94 samples were included and analyzed in this study with bacterial meningitis. Neutrophil lymphocyte ratio >5.225 was a significant predictor of mortality in patients with bacterial meningitis with p = 0.004 and risk ratio 10.78. Other factors that were significant predictors of mortality included the pediatric coma scale ≤8 and positive cerebrospinal fluid culture. CONCLUSION: Neutrophil lymphocyte ratio is a statistically significant predictor of mortality in patients with bacterial meningitis, and can be used as a parameter to predict outcomes in patients with bacterial meningitis.

Acute appendicitis in pediatric patients with Coronavirus Disease 2019 (COVID-19): A case series from a developing country's tertiary hospital.

INTRODUCTION: and importance: A common gastrointestinal presentation of both COVID-19 and multisystem inflammatory syndrome in children (MIS-C) is acute abdominal pain, which sometimes mimics appendicitis. Literature describing children with COVID-19 infection and concurrent acute appendicitis is growing, and understanding these patients' clinical picture is necessary for their proper treatment. CASE PRESENTATION: We present a case series of six healthy children before they developed classic symptoms of appendicitis. At the same time, they were also found to have confirmed COVID-19. All patients had fever and right lower abdominal pain. Four of six children having Alvarado score above seven had surgical treatment, while the others only received systemic antibiotic and antiviral medication. Surgical results of two patients revealed perforated appendicitis. No mortality occurred among them. CLINICAL DISCUSSION: There is increasing recognition of gastrointestinal involvement in patients with COVID-19 and MIS-C. There are several postulates to explain appendicitis in COVID-19. First, inflammatory response is exaggerated in SARS-CoV-2 infected patients. Second, obstruction of the appendiceal lumen is caused by mesenteric adenopathy, which in turn, is caused by COVID-19 infection, not fecalith. Third, hyperinflammatory response in MIS-C triggers inflammation in appendix. CONCLUSION: Clinicians must recognize that abdominal pain with fever could be the presenting symptoms of COVID-19 with MIS-C. MIS-C, which has severe presentations with gastrointestinal manifestations and high mortality rate, should be considered as a differential diagnosis for a patient with appendicitis-like symptoms and a positive SARS-CoV-2 infection.

Comprehensive management of refractory autoimmune hemolytic anemia in pediatric beta-thalassemia major patient: A case report.

INTRODUCTION: and importance: Autoimmune hemolytic anemia (AIHA) is characterized by the production of antibodies against the red blood cells (RBCs) leading to increased hemolysis. Incidence of AIHA in patients with beta-thalassemia major is 5 of 100 thalassemia patients. CASE PRESENTATION: A 15-year-old female patient with refractory AIHA and thalassemia was unresponsive to steroid therapy. In this report, she was treated with cyclosporine and prednisone in addition to leucodepleted packed red cell (PRC). She was successfully got remission during one-year monitoring. CLINICAL DISCUSSION: Cyclosporine is an immunosuppressive agent that interferes with T-cells activation by inhibiting transcription of cytokines, such as interleukin 2 and interferon-É£. Cyclosporine and steroid have synergic effects to prevent antibody production. Nephrotoxicity is one of the most concerning effect in cyclosporine usage, but it rarely develops using doses lower than 5 mg/kgBW/day. In limited resources blood bank with ABO and Rh crossmatch only, leucodepleted PRC transfusion could be an effective way to prevent antibody formation to minor blood group. CONCLUSION: Cyclosporine and steroid could be considered for management in refractory AIHA with thalassemia patients. Non-pharmacological therapy such as leucodepleted PRC transfusion and limited donor transfusion could be considered.

Factors associated with mortality in intracranial infection patients admitted to pediatric intensive care unit: A retrospective cohort study.

BACKGROUND: Intracranial infection is a major cause of emergency and death in children. To assist clinical decision-making in patient management, we conducted a study about factors associated with mortality. This study aimed to evaluate factors associated with mortality in pediatric patients with intracranial infection. METHODS: We performed a cohort retrospective study in our tertiary hospital to evaluate the outcomes of patients admitted to the pediatric intensive care unit (PICU) from 2014 to 2018. The Chi-square test was performed to determine the significance of the predictor, and p < 0.05 was considered to indicate a statistically significant result. We used multivariate logistic regression to determine relative risk (RR) with 95% confidence interval (CI). RESULTS: We recruited 112 patients who were admitted to the PICU of our tertiary hospital. A total of 38.4% were diagnosed with encephalitis, 9.8% meningitis and 51.8% meningoencephalitis. Of the 112 patients who met the inclusion criteria, 28 (25%) patients died in the PICU. The need of mechanical ventilation support variable had a statistically significant association with mortality (RR 22.76; 95% CI: 3.88-51.45). CONCLUSION: Recognition of conditions that exacerbate intracranial infection in children needs to be done as early as possible. Moreover, the need of mechanical ventilation support in the PICU needs more attention.

Factors associated with mortality of pediatric sepsis patients at the pediatric intensive care unit in a low-resource setting.

BACKGROUND: Sepsis is the leading cause of death worldwide in pediatric populations. Studies in low-resource settings showed that the majority of pediatric patients with sepsis still have a high mortality rate. METHODS: We retrospectively collected records from 2014 to 2019 of patients who had been diagnosed with sepsis and admitted to PICU in our tertiary hospital. Cox proportional hazard regression modeling was used to evaluate associations between patient characteristics and mortality. RESULTS: Overall, 665 patients were enrolled in this study, with 364 (54.7%) boys and 301 (46.3%) girls. As many as 385 patients (57.9%) died during the study period. The median age of patients admitted to PICU were 1.8 years old with interquartile range (IQR) ±8.36 years and the median length of stay was 144 h (1-1896 h). More than half 391 patients (58.8%) had a good nutritional status. Higher risk of mortality in PICU was associated fluid overload percentage of > 10% (HR 9.6, 95% CI: 7.4-12.6), the need of mechanical ventilation support (HR 2.7, 95% CI: 1.6-4.6), vasoactive drugs (HR 1.5, 95% CI: 1.2-2.0) and the presence of congenital anomaly (HR 1.4, 95% CI: 1.0-1.9). On the contrary, cerebral palsy (HR 0.3, 95% CI: 0.1-0.5) and post-operative patients (HR 0.4, 95% CI: 0.3-0.6) had lower mortality. CONCLUSION: PICU mortality in pediatric patients with sepsis is associated with fluid overload percentage of > 10%, the need for mechanical ventilation support, the need of vasoactive drugs, and the presence of congenital anomaly. In septic patients in PICU, those with cerebral palsy and admitted for post-operative care had better survival.

Post-herniorrhaphy extubation technique in pediatric patient with congenital diaphragmatic hernia and VACTERL association: A case report.

INTRODUCTION: and importance: Congenital diaphragmatic hernia (CDH) is a condition characterized by a defect in the diaphragm causing protrusion of abdominal organs into the thoracic cavity. Comprehensive management, definitive surgical procedures and postoperative care are able to significantly reduce morbidity and mortality in post-herniorrhaphy patients. Here, we reported a case of post herniorrhaphy pediatric patient with a challenge in extubation. CASE PRESENTATION: A 4-month-old girl with a chief complaint of respiratory distress from was admitted to our Pediatric Intensive Care Unit. The diagnosis of diaphragmatic hernia was confirmed through small bowel follow-through radiological examination. Definitive treatment of laparotomy and herniorrhaphy were then done. The special technique for extubation was applied. Currently, the patient survives without any sequelae awaiting stoma closure. CLINICAL DISCUSSION: Extubation is the removal of an endotracheal tube when it is no longer needed. In mechanically ventilated patients, extubation can be performed in two ways, either using the tracheal suction catheter (TSC) or positive pressure breath (PPB) techniques. Studies show that the PBB extubation technique has better patient outcomes compared to the TSC technique. However, the TSC technique is more commonly done by medical professionals. We used the PPB technique because there were recurrent atelectases in the left lung. CONCLUSION: This case report illustrates extubation technique in a post-herniorrhaphy patient with congenital diaphragmatic hernia and VACTERL association. Moreover, several options of extubation techniques can be used for extubation procedure in pediatric patient with CDH.

Association of soluble ST2 and infarct location within 12-24 h in STEMI: A cross-sectional study.

BACKGROUND: ST-Segment Elevation Myocardial Infarction (STEMI) causes the release of soluble ST2 biomarkers at high level on acute phase. However, sST2 has never been used as adjunct biomarker in ESC/AHA guideline for STEMI. Furthermore, the specific onset that sST2 may have role in acute phase of STEMI related with infarct location has not been established. This study aimed to prove the association between serum ST2 levels and infarct location in STEMI. MATERIAL AND METHODS: This study was cross-sectional. STEMI patients with onset of anginal pain 12-24 h were included in study. The exclusion criterias were patients with AMI aside from STEMI and other potential confounders affecting the sST2 level. Serum sST2 was collected on first medical contact when admitted to emergency unit. The patients were grouped into anterior STEMI and non-anterior STEMI. sST2 levels were compared with demographics data, clinical and laboratory variables using Student's t-test. Correlation of sST2 levels was analyzed using Spearman's correlation coefficient. RESULTS: 19 subjects were included in the anterior STEMI and 20 subjects were included in the non-anterior STEMI. We found no difference in sST2 levels between anterior STEMI and non-anterior STEMI (mean ± SD; 729.97 pg/mL ± 147.78 pg/mL vs 606.87 pg/mL ± 147.78 pg/mL, p = 0.119). Onset was correlated with serum sST2 levels in male subjects (r = -0.459, p = 0.012). We found significant difference of mean sST2 between 2 onset groups divided at median (12-18 h vs 19-24 h, Δ mean = 107.75 pg/mL, p-value = 0.021). CONCLUSION: sST2 was not associated with infarct location within 12-24 h onset of STEMI. This results suggest that infarct location might not responsible for the elevation of serum sST2 levels in acute phase of STEMI.

Obstructive shock in pediatric patient with congenital cystic adenomatoid malformation: A case report.

INTRODUCTION: and importance: Congenital cystic adenomatoid malformation (CCAM) is a rare cystic lesion in the lungs. CCAM might present in the early neonatal period with symptoms of respiratory distress. CASE PRESENTATION: A 2-year-old girl was admitted to our Pediatric Intensive Care Unit with signs of severe respiratory distress. She had been diagnosed with CCAM since she was three months old. She also had undergone several procedures such as thoracotomy and decortication since then, but she still suffered some episodes of pulmonary infection. In this admission, her computerized thoracic tomography revealed a pleuropulmonary blastoma (PPB). CLINICAL DISCUSSION: An obstruction of blood outflow from the left ventricle could happen when an intrathoracic mass exists, leading to a decrease of cardiac output and resulting in an obstructive shock, which could be fatal. One of the malignancy types commonly occurring is pleuropulmonary blastoma (PPB), which has a poor prognosis. Early detection on CCAM can be done by prenatal ultrasound. CONCLUSION: Obstructive shock is one of complication that might occur in pleuropulmonary blastoma.

Diagnostic challenges of hemophagocytic lymphohistiocytosis in child with multiorgan dysfunction in a low-resource setting: A case report.

INTRODUCTION: and importance: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening hyperinflammatory syndrome as a result of dysregulation of the immune system. Physicians in the intensive care unit (ICU), especially pediatricians, need to know how to recognize the diagnostic criteria and spectrum of HLH clinical presentations because early detection and timing of initial therapy affect the survival rate of the patient. CASE PRESENTATION: A 7-year-old female patient was referred to the pediatric ICU (PICU) at our tertiary hospital because of the suspicion of severe sepsis with shock and disseminated intravascular coagulation. On the fifth day of treatment, the patient was intubated and given a mechanical ventilator after experiencing respiratory failure. On the seventh day in the PICU, high fever persisted and the patient developed worsening acute kidney injury with oliguria. When worsening conditions continued, the patient experienced hypotension and cardiac arrest. The patient died on the 8th day of treatment at PICU due to severe shock and multiorgan failure. CLINICAL DISCUSSION: HLH complications can be life-threatening with documented ICU mortality of 35%, even with an appropriate initial therapeutic approach. Patients with HLH can have rapid progression of disease and often require a significant amount of ICU supportive care, including vasopressor support, significant amount of blood products, ventilator support, and renal replacement therapy. CONCLUSION: The diagnosis of HLH should be considered if there are cases with persistent, prolonged fever, organomegaly, cytopenias and evolving Multi Organ Dysfunction Syndrome. It is important for pediatricians to know the diagnostic criteria and possible clinical presentations of HLH.

TGF-ß expression on different suturing technique for abdominal skin wound closure in rats.

BACKGROUND: The method of closing the abdominal wall, as well as, the choice of material for stitching are important aspects of efficient incision closure. Generally, transforming growth factor-beta (TGF-ß) is involved in the wound healing process. Suturing procedures also play a part in the wound dehiscence occurrence. This study aimed to compare TGF-ß expressions in rats after using the large stitch vs. small stitch technique for abdominal skin wound closure. METHODS: A total of twenty Wistar rats (Rattus norvegicus) were used in this experiment. Small tissue bites of 5 mm were obtained by the small stitch group and the large stitch group received large bites of 10 mm. Abdominal skin incisions were closed by running sutures. On days 4 and 7, the animals were euthanized. For TGF-ß expressions, histological parts of the tissue-embedded sutures were analyzed. With significance set at p < 0.05, two-way ANOVA showed that on days 4 and 7, the TGF-ß expressions of the rats in the small stitch group were nearly identical to those in the large stitch groups. RESULTS: After including twenty rats in this study, results showed the TGF-ß expressions on days 4 and 7 in rats in the small stitch group were equivalent to those in the large stitch group. (p = 0.45). CONCLUSIONS: Between the small and the large stitch groups, the TGF-ß expressions are similar, suggesting that the suturing methods do not have any significantly different beneficial impact on the frequency of wound dehiscence.
