Regarding poor detection of bronchial asthma (BA) in outpatient facilities diagnostic values of main clinical and phenotypical BA signs were investigated to improve early diagnosis of the disease. To verify the diagnosis we elaborated a clinic variant of BA, assessed medical documents and questioned 96 patients. The correct diagnosis was found to be reached usually in some years after the appearance of the first BA symptoms (in average 12.49 ± 7.32 yrs) in spite of typical onset of the disease in all the cases: dry cough attacks in 82.2 %, asthma attacks in 6.3 %, dyspnoea in 46.9 %, and chest tightness while contacting with an allergen or an unspecific irritant (dynamic physical exercise, stress, cold air) in 7.3 % of the patients. Detailing of symptoms was performed and diagnostic value of every sign was determined. Discriminative coefficients were calculated for reliably high influencing signs; their informative values and probability of BA detection were defined. Subjective and objective causes of late BA diagnosis were retrospectively analyzed based on medical documentation and questioning 92 doctors of outpatient facilities.

Asthma In Children

Respiratory allergies are one of the most common and severe allergic pathologies in children. Our observations showed that bronchial asthma is formed in more than 80% of children through the stage of pre-asthma. However, its early diagnosis and adequate treatment in 90% of cases can prevent the transition to bronchial asthma. In this regard, the problem of studying the methods of early diagnosis of pre-asthma and ways to prevent its transformation into bronchial asthma is urgent and practically significant. Since the formation of pre-asthma and bronchial asthma is based on a violation of the function of external respiration, the purpose of our work was, firstly, to study the function of external respiration in case of pre-asthma, and secondly, to determine the diagnostic value of various methods for studying FVD in this pathology in children.

Abstract Background MicroRNA-155 (miR-155) may function as a diagnostic biomarker of breast cancer (BC). Nevertheless, the available evidence is controversial. Therefore, we performed this study to summarize the global predicting role of miR-155 for early detection of BC and preliminarily explore the functional roles of miR-155 in BC. Methods We first collected published studies and applied the bivariate meta-analysis model to generate the pooled diagnostic parameters of miR-155 in diagnosing BC such as sensitivity, specificity and area under curve (AUC). Then, we applied function enrichment and protein–protein interactions (PPI) analyses to explore the potential mechanisms of miR-155. Results A total of 21 studies were finally included. The results indicated that miR-155 allowed for the discrimination between BC patients and healthy controls with a sensitivity of 0.87 (95% CI 0.78–0.93), specificity of 0.82 (0.72–0.89), and AUC of 0.91 (0.88–0.93). In addition, the overall sensitivity, specificity and AUC for circulating miR-155 were 0.88 (0.76–0.95), 0.83 (0.72–0.90), and 0.92 (0.89–0.94), respectively. Function enrichment analysis revealed several vital ontologies terms and pathways associated with BC occurrence and development. Furthermore, in the PPI network, ten hub genes and two significant modules were identified to be involved in some important pathways associated with the pathogenesis of BC. Conclusions We demonstrated that miR-155 has great potential to facilitate accurate BC detection and may serve as a promising diagnostic biomarker for BC. However, well-designed cohort studies and biological experiments should be implemented to confirm the diagnostic value of miR-155 before it can be applied to routine clinical procedures.

Underlying Causes

Children with recurrent or persistent pneumonia often have underlying chronic cardiopulmonary disease, but few reports on this subject have been published. Children with isolated common cardiac diseases, uncomplicated bronchial asthma or with incomplete records were excluded. Of 4361 children followed during a five-year period, 107 were included in our study. Underlying causes were identified in 99.0%: immunodeficiency disorders (20.2%), cardiothoracic malformations (18.3%), syndromic conditions (14.4%), infections (10.6%) bronchiectasis (10.6%), gastro-oesophageal reflux disease (6.6%), interstitial lung disease (3.8%) and other miscellaneous conditions (15.4%). Thus, children with recurrent or persistent pneumonia should be carefully evaluated for an underlying aetiology, as early diagnosis and appropriate management will decrease morbidity and mortality in most of these children.

This study aimed to investigate whether the incorporation of contrast-enhanced harmonic endoscopic ultrasound (CH-EUS) into the international consensus guidelines (ICG) for the management of intraductal papillary mucinous neoplasm (IPMN) could improve its malignancy diagnostic value. In this single-center retrospective study, 109 patients diagnosed with IPMN who underwent preoperative CH-EUS between March 2010 and December 2018 were enrolled. We analyzed each malignancy diagnostic value (sensitivity (Se), specificity (Sp), positive predictive value (PPV), and negative predictive value (NPV)) by replacing fundamental B-mode EUS with CH-EUS as the recommended test for patients with worrisome features (WF) (the CH-EUS incorporation ICG) and comparing the results to those obtained using the 2017 ICG. The malignancy diagnostic values as per the 2017 ICG were 78.9%, 42.3%, 60.0%, and 64.7% for Se, Sp, PPV, and NPV, respectively. The CH-EUS incorporation ICG plan improved the malignancy diagnostic values (Se 78.9%/Sp, 53.8%/PPV, 65.2%/NPV 70.0%). CH-EUS may be useful in determining the appropriate treatment strategies for IPMN.

Multi-parameter magnetic resonance imaging has been widely used in the diagnosis and evaluation of prostate cancer, and has important guiding significance for clinical diagnosis of prostate cancer and their treatment. This article studies the value of transrectal multiparametric ultrasound (mpUSS) in the diagnosis of clinically meaningful prostate cancer. 102 patients with high risk factors for prostate cancer were examined by mpUSS and mpMRI. The transrectal biopsy (SB) results of the prostate system were regarded as the excellent standard, and the diagnostic value of mpUSS, mpMRl and mpUSS combined with mpMRl examination for clinically meaningful prostate cancer was analyzed. The results showed that 58 of the 102 patients with SB were diagnosed with prostate cancer. Among them, 43 cases were detected by mpUSS, 50 cases were detected by mpMRl, 42 cases were detected by mpUSS combined with mpMRI (series), and 56 cases were detected by mpUSS combined with mpMRl (parallel). Grouped by Gleason score, the detection rate of mpUSS for clinically significant prostate cancer was 83.74%, and the detection rate of mpMRl was 93.5%. The comparison between the two was not statistically significant (P > 0.05), but when the two inspection methods were combined. The detection rate was 97.8%, which was significantly higher than the two inspection methods alone. Therefore, we conclude that mpUSS can be used as an imaging test for the diagnosis of prostate cancer. In addition, mpUSS has a high application value in the diagnosis of prostate cancer. The detection rate of mpUSS combined with mpMRl examination for clinically meaningful prostate cancer is significantly higher than that of mpMRl examination alone, which can be used as a diagnostic technique for early diagnosis of meaningful prostate cancer and can be used as a guide clinicians’ early diagnosis and treatment of meaningful prostate cancer.

Canine Ehrlichiosis

Early diagnosis of canine ehrlichiosis favors prompt institution of treatment and improves the prognosis for the animal, since this disease causes mortality among dogs. Studies have shown that determining the concentration of acute-phase proteins (APPs) may contribute towards early detection of disease and aid in predicting the prognosis. This study aimed to evaluate the APP profile in dogs experimentally infected with Ehrlichia canis, at the start of the infection and after treatment. It also investigated whether any correlation between APP levels and the clinical and laboratory alterations over the course of the disease would be possible. The results obtained showed abnormal levels of all the APPs on the third day after infection (D3), with the highest levels being reached on D18, with the exception of ceruloplasmin and acid glycoprotein, which presented their peaks on D6 and D12 respectively. We concluded that assessment of APP levels could contribute towards establishing an early diagnosis of canine ehrlichiosis, particularly regarding acid glycoprotein and ceruloplasmin, since these proteins were detected at increased levels even before the onset of clinical and laboratory findings of the disease.

Background: Neonatal Gastric Perforation (NGP) is a serious and life-threatening emergency and challenging in terms of diagnosis and management.  The precise aetiology remains obscure in most cases. Published literatures provide theories of gastric ischemia, aerophagia & trauma with or without definite inciting pathology.  Owing to its high mortality rate, it requires early detection & urgent intervention to bring out the newborn from this catastrophe.Methods: We report five cases of neonatal gastric perforation over period of 2013-2019 admitted to a tertiary paediatric surgical care hospital managed by early detection, prompt resuscitation along with exploration and primary repair of the defect in gastric wall.Results: The common feature in these five cases were preterm age, low birth weight, hypoxic event   and   marked abdominal distension causing respiratory distress.  Features of imminent or complete septic shock were present in all cases. Perforation was found on anterior wall along greater curvature of stomach in all babies. Four babies out of five survived except in one case of jejunoileal Artesia that developed gastric perforation in post operative period.Conclusions: Neonatal gastric perforation should be suspected in cases of rapidly deteriorating premature newborn with gross abdominal distension and pneumoperitoneum. In our opinion, etiology of NGP is multifactorial. Prematurity, low APGAR score with vigorous resuscitation could be a clue for early diagnosis. Good outcome in our series was due to early diagnosis and prompt pre and postoperative measures. Additionally, sterile gastric content in peritoneum  might lead to survival from this catastrophic event.

Background: Cirrhosis is a common disease that destroys liver cells, and it has various etiologies. The early diagnosis of cirrhosis can be effective in improving prognosis.Considering the availability and affordability of ultrasound devices throughout the world, in this study we evaluated the diagnostic value of hepatic vein ultrasound examination in the early detection of liver cirrhosis.Materials and Methods: In this study, 45 patients referred to the radiology department of Ghaem Hospital for liver biopsy were evaluated for changes in the hepatic veins under ultrasound with a transducer of 5-7MHz. One piece of the hepatic vein was selected for ultrasound, and the wall of hepatic veins was examined for straightness and uniformity of echogenicity. Subsequently, patients underwent biopsy by ultrasound guide.  Of all the study subjects, eight patients presented mild chronic hepatitis without fibrosis, four patients were diagnosed with fatty liver, and 33 patients had severe cirrhosis or chronic hepatitis with fibrosis.Results: Our results showed that hepatitis patients with or without fibrosis had irregular and wavy hepatic vein wall (impairment in straightness) with non-uniform echo (impairment in uniformity of echogenicity). While patients without hepatitis and cirrhosis, but diagnosed with fatty liver, had a smooth and regular hepatic vein wall with a uniform echo.Conclusion: The present study showed that hepatic vein examination in terms of echogenicity and straightness could be used to diagnose hepatitis, its severity as well as its course towards fibrosis and cirrhosis. [GMJ.2018;7:e1140]
