Clinical Utility of Respiratory Scores at Admission for Estimating the Definitive Microbiological Diagnosis in Lower Respiratory Tract Infections in Infants

We aimed at determining the clinical utility of respiratory scores and the durations of wheezing or respiratory distress during hospitalization in infants with lower respiratory tract infections (LRTI) at admission for estimating the definitive microbiological diagnosis. We obtained data from a study population of 201 patients, 79 girls and 122 boys. There was a significant divide in the causative agents of LRTI among patients younger and older than 6 months of age (P = .002), and significantly different respiratory score findings were determined in infants with viral LRTI: a low respiratory score in a younger-than-6 month infant suggests Adenovirus as the causative agent and a high respiratory score suggests Parainfluenza 1 or 2; as for infants of 6 months of age or older, a low respiratory score indicates Influenza A or B or a mixed infection, whereas a high respiratory score is likely an indication of Parainfluenza 3 or RSV.Peer reviewe

Effect of Breastfeeding and Preterm Births on the Severity of Lower Respiratory Tract Infections and Associated Risk of Hospitalization in Infants and Toddlers

We studied the effect of duration of breastfeeding and history of prematurity on the duration of hospitalization in infants with lower respiratory tract infections (LRTI) because these may reflect the severity of illness as well as sizable direct and indirect healthcare costs. One hundred twenty-five patients (49 girls, 76 boys; aged 1-24 months) were hospitalized for LRTI during a period of 102 days and studied prospectively. We found a significant difference (P = .045) between the durations of hospitalization of the 92 patients breastfed for at least six months, compared to the other group of 33 patients who were breastfed for less than six months. The durations of hospitalization among the groups with and without a history of prematurity were not statistically different (P = .78). A history of breastfeeding for more than six months had significant effect on the duration of hospitalization, but this was not true for children with a history of preterm birth.Peer reviewe

Neonatal Hypopituitarism: Approaches to Diagnosis and Treatment

Hypopituitarism is defined as a decreased release of hypophyseal hormones, which may be caused by disease of the pituitary gland disease or hypothalamus. The clinical findings of neonatal hypopituitarism depend on the causes and on presence and extent of hormonal deficiency. Patients may be asymptomatic or may demonstrate non-specific symptoms, but may still be at risk for development of pituitary hormone deficiency over time. Patient history, physical examination, endocrinological, radiological and genetic evaluations are all important for early diagnosis and treatment. The aim of this paper was to present a review of etiological factors, clinical findings, diagnosis and treatment approaches in neonatal hypopituitarism

IMP3 expression in urothelial carcinomas of the urinary bladder

Objective: Superficial tumors including Ta, Tis, and T1 make up 75% of urothelial carcinomas of the bladder. While the behavior of these superficial urothelial cancers is relatively benign, invasive tumors have a significant mortality rate. However, Ta and T1 tumors might display different biological behavior. There is therefore a great need for biomarkers that can accurately distinguish the behavior of urothelial carcinomas in addition to tumor grade and stage. Our aim was to determine the immunohistochemical expression profile of insulin like growth factor II mRNA binding Protein 3 (IMP3) and its correlation with tumor stage and grade in benign urothelium and bladder urothelial carcinomas. Material and Method: The expression of IMP3 in 91 patients with benign urothelium (20 cases), low grade invasive (17 cases) / noninvasive (20 cases) urothelial carcinoma and high grade invasive (20 cases) / non-invasive (14 cases) urothelial carcinoma was evaluated by immunohistochemistry in this study. Results: IMP3 was not expressed in benign urothelium, low-grade non-invasive urothelial carcinoma and high grade non-invasive urothelial carcinoma. Expression of IMP3 was found in 11.76% of low-grade invasive urothelial carcinomas and 55% of high grade invasive urothelial carcinomas. Statistical analysis including χ2 tests showed that IMP3 expression of invasive urothelial carcinomas was statistically significant (p<0.000). Conclusion: The detection of IMP3 only in invasive carcinomas although some of them were low grade showed that the expression of IMP3 may be related to aggressive behavior of urothelial carcinomas

Short-term Postoperative Outcomes of Platelet-rich Plasma after Inferior Turbinate Radiofrequency

Introduction:To evaluate the effect of submucosal platelet-rich plasma (PRP) therapy on intraoperative bleeding and early postoperative pain and crusting in patients undergoing inferior turbinate radiofrequency.Methods:A total of 70 adult patients with isolated inferior turbinate hypertrophy were included in this prospective study and randomized to the PRP or control groups. PRP was prepared for all patients. After applying submucosal radiofrequency to the inferior turbinates under local anesthesia, submucosal PRP was injected into the study group, and submucosal saline was injected into the control group. Patient controls were performed by another specialist. The patients and the specialist who performed the controls were blinded to which group they were in. All patients were evaluated endoscopically 1, 7, and 21 days after the operation.Results:The mean age of the patients was 33.37±11.92 years (range: 18 to 54). The two groups had no significant differences in intraoperative bleeding and mucociliary clearance values (p>0.05). The amount of crusting and the visual analog scale pain values were significantly lower in the submucosal PRP -injected group (p<0.05).Conclusion:Submucosal injection of PRP after radiofrequency of the inferior turbinate reduces nasal obstruction and pain due to crusting. With these features, it can be concluded that this procedure accelerates recovery and increases patient comfort in the early postoperative period

Evaluation of Left Ventricular Function by Conventional Echocardiography and Tissue Doppler Imaging in Patients with Acute and Chronic Mitral Regurgitation

Left ventricular function is affected differently in acute and chronic mitral regurgitation (MR). Twenty-six patients (12 men and 14 women, average age: 55±20 years) with acute severe MR caused by flail leaflet and 30 patients with chronic severe MR of organic origin (14 men and 16 women, average age: 56±14 years) were included in the study. All of the patients were evaluated in detail by conventional echocardiography and tissue Doppler imaging (TDI). Among conventional echocardiographic parameters, left ventricle ejection fraction (%) was found higher in acute MR (71±5/59±12, p=0.001) whereas left ventricle end-systolic volume, left ventricle end-diastolic volume, left ventricle end-systolic diameter, left ventricle end-diastolic diameter, left atrium dimension, and left atrial area were significantly higher in chronic MR. Among TDI parameters, peak systolic wave velocities (11.4±3.6/8.8±2.5cm/s, p=0.018), peak early diastolic velocities (10.8±4.5/9.3±3.8cm, p=0.03), and contraction time (248±56/219±47ms, p=0.04) were found higher in acute MR, whereas precontraction time (119±29/164±48ms, p=0.005) and precontraction time to contraction time ratio (0.52±0.23/0.78±0.28, p=0.008) were significantly higher in chronic MR. As evaluated by conventional echocardiography, the systolic function of chronic MR was also normal, although it was lower than that of acute MR. We also found that left ventricular systolic and diastolic functions by TDI were also relatively preserved in patients with acute MR when compared with those with chronic MR

Blau Syndrome and Early-Onset Sarcoidosis: A Six Case Series and Review of the Literature.

Objectives: This study aims to discuss the clinical, laboratory and genetic findings, and treatment options for six patients who were diagnosed with Blau syndrome (BS)/early-onset sarcoidosis (EOS). Patients and methods: The study included four patients (2 males,2 females; mean age 7 years; range 4 to 10 years) with EOS and two siblings (1 male, 1 female; mean age 10 years; range, 9 to 11 years) with BS. Age, age of initial symptoms, age of diagnosis; articular involvement, presence of uveitis, dermatitis, or fever, other organ involvement, laboratory findings, results of metabolic tests for mucopolysaccharidosis and mucolipidosis, results of genetic, pathologic, and immunologic tests, radiologic findings to evaluate skeletal dysplasia, and treatment options were collected. Results: The median age at diagnosis of all patients was 6 years (range, 1 to 10 years). Five patients had camptodactyly and bilateral boggy synovitis in the wrists and ankles, one had granulomatous inflammatory changes in the liver and kidney biopsy, and one had attacks of fever and granulomatous dermatitis. None had uveitis. The detected mutations in nucleotide-binding oligomerization domain containing 2 (NOD2) were P268S (rs2066842), M513T (rs104895473), R702W (rs2066844), V955I (rs5743291), H343Y (rs199858111), and M491L (16:50745293). The treatments of patients included corticosteroids, non-steroid anti-inflammatory drugs, methotrexate, infliximab, adalimumab, anakinra, and canacinumab. Conclusion: Camptodactyly and boggy synovitis are important signs of BS/EOS. Methotrexate and tumor necrosis factor blockers are more effective in patients with predominantly articular symptoms. In patients 5 and 6 and their mother, we determined a novel M491L mutation in the NOD2 gene. Currently, this work is in progress towards identifying the pathogenesis and treatment options for this disease

Akut pulmoner embolide senkopun klinik, görüntüleme ve hemodinamik korelasyonları ve prognostik etkisi: Tek merkezli bir çalışma

Background: We aimed to determine the clinical, echocardiographic and hemodynamic correlates of syncope as a presenting symptom in pulmonary embolism and its impact on in-hospital and long-term outcomes. Methods: Between July 2012 and October 2019, a total of 641 patients with PE (277 males, 364 females; median age: 65 years; range, 51 to 74 years) in whom the diagnostic work-up and risk-based management were performed according to the current pulmonary embolism guidelines were retrospectively analyzed. Clinical, laboratory and imaging data of the patients were obtained from hospital database system. Results: Syncope was noted in 193 (30.2%) of patients on admission, and was associated with a significantly higher-risk status manifested by elevated troponin and D-dimer levels, a higher Pulmonary Embolism Severity Index scores, deterioration of right-to-left ventricular diameter ratio, right ventricular longitudinal contraction measures, the higher Qanadli score, and higher rates of thrombolytic therapies (p<0.001) and rheolytic– thrombectomy (p=0.037) therapies. In-hospital mortality (p=0.007) and minor bleeding (p<0.001) were significantly higher in syncope subgroup. Multivariate logistic regression analysis showed that higher Pulmonary Embolism Severity Index scores and right-to-left ventricular diameter ratio were independently associated with syncope, while aging and increased heart rate predicted in-hospital mortality. Malignancy and right-to-left ventricular diameter ratio at discharge, but not syncope, were independent predictors of cumulative mortality during follow-up. Conclusion: Syncope as the presenting symptom is associated with a higher risk due to more severe obstructive pressure load and right ventricular dysfunction requiring more proactive strategies in patients with pulmonary embolism. However, with appropriate risk-based therapies, neither in-hospital mortality nor long-term mortality can be predicted by syncope.Amaç: Bu çalışmada pulmoner embolide başvuru anında senkopun klinik, ekokardiyografik ve hemodinamik korelasyonları ve hastane içi ve uzun dönem sonuçlar üzerindeki etkisi incelendi. Ça­lış­ma pla­nı: Temmuz 2012-Ekim 2019 tarihleri arasında tanı testleri ve risk esaslı tedavisi mevcut pulmoner emboli kılavuzlarına göre yapılan toplam 641 pulmoner emboli hastası (277 erkek, 364 kadın; ort. yaş: 65 yıl; dağılım, 51-74 yıl) retrospektif olarak incelendi. Hastaların klinik, laboratuvar ve görüntüleme verileri hastane veri tabanı sisteminden elde edildi. Bulgular: Başvuru anında hastaların 193’ünde (%30.2) senkop belirlendi ve artmış troponin ve D-dimer düzeyleri, yüksek Pulmoner Emboli Şiddet İndeks skorları, sağ-sol ventrikül çapı oranında ve sağ ventrikülün uzunlamasına kontraksiyon ölçümlerinde kötüleşme, yüksek Qanadli skoru ve yüksek trombolitik tedavi (p<0.001) ve reolitik-trombektomi tedavi (p=0.037) oranları ile belirlendiği üzere anlamlı düzeyde daha yüksek risk durumu ile ilişkili bulundu. Hastane içi mortalitesi (p=0.007) ve minör kanama (p<0.001) senkop alt grubunda anlamlı düzeyde daha yüksek idi. Çok değişkenli lojistik regresyon analizinde, yüksek Pulmoner Emboli Şiddet İndeks skorları ve sağ-sol ventrikül çapı oranı senkop ile bağımsız düzeyde ilişkili bulunurken, yaşlanma ve artmış kalp hızı hastane içi mortalitesinin öngördürücüsüydü. Senkop değil fakat malignite ve taburculuk anında sağ-sol ventrikül çapı oranı, takip süresince toplam mortalitenin bağımsız öngördürücüleri idi. So­nuç: Başvuru semptomu olarak senkop, pulmoner embolide daha proaktif stratejiler gerektiren daha şiddetli tıkayıcı basınç yüküne ve sağ ventrikül disfonksiyonuna bağlı daha yüksek risk ile ilişkilidir. Ancak, riske göre uygun tedaviler uygulandığında ne hastane-içi mortalite ne de uzun dönem mortalite senkop tarafından öngörülebilmektedir

Ses kısıklığının ciddi pulmoner hipertansiyonu olan hastalarda pulmoner arter anevrizması ve sol ana koroner artere dıştan basıyı göstermedeki rolü

OBJECTIVE: Pulmonary artery (PA) enlargement is a common finding in patients with severe pulmonary hypertension (PH) and may be associated with extrinsic compression of the left main coronary artery (LMCA-Co) and/or compression of the left recurrent laryngeal nerve resulting in hoarseness named as Ortner syndrome (OS). In this study, we evaluated the diagnostic impact of OS in predicting the PA aneurysm and significant LMCA-Co in patients with PH. METHODS: Our study population comprised retrospectively evaluated 865 with PH confirmed with the right heart catheterization between 2006 and 2022. Patients underwent coronary angiography due to several indications, including the presence of a PA aneurysm on echocardiography, angina symptoms, or the incidental discovery of LMCA-Co on multidetector computed tomography. The LMCA-Co is defined as diameter stenosis ³ 50% in reference distal LMCA segment on two consecutive angiographic planes. RESULTS: The LMCA-Co and hoarseness were documented in 3.8% and 4.3% of patients with PH, respectively. Increasing PA diameter was significantly associated with worse clinical, hemodynamic, laboratory, and echocardiographic parameters. The receiver operating curves revealed that the PA diameter >41 mm was cutoff for hoarseness (AUC: 0.834; sensitivity 69%, specificity 84%, and negative predictive value 98%), and PA diameter >35 mm was cutoff for LMCA-Co >50% (AUC: 0.794; sensitivity 89%, specificity 58 %, and negative predictive value 99%). An odds ratio of hoarseness for LMCA-Co was 83.3 (95% confidence interval; 36.5-190, P < 0.001) with 3.2% sensitivity, 98.7% specificity, and 59% positive and 98% negative predictive values. CONCLUSION: In this study, a close relationship was found between the presence of hoarseness and the probability of extrinsic LMCA-Co by enlarged PA in patients with severe PH. Therefore, the risk of LMCA-Co should be taken into account in patients with PH suffering from hoarseness.Amaç: Pulmoner arter (PA) genişlemesi, şiddetli pulmoner hipertansiyonu (PH) olan hastalarda sık görülen bir bulgu olup Ortner sendromu (OS) adını alarak sol ana koroner arterin (LMCA) dıştan basısı ve/veya sol rekürren laringeal sinirin basısı ile sonuçlanarak ses kısıklığına neden olabilir. Bu çalışmada OS’nin PH hastalarında PA anevrizmasını ve anlamlı LMCA basısını öngördürmede tanısal etkisini değerlendirmeyi amaçladık. Yöntem: Çalışma popülasyonu, 2006 ve 2022 yılları arasında sağ kalp kateterizasyonu ile doğrulanan PH ile retrospektif olarak değerlendirilen 865 hastayı içermektedir. Hastalara, ekokardiyografide PA anevrizmasının varlığı, anjina semptomları veya çok kesitli bilgisayarlı tomografide tesadüfen LMCA basısı saptanması gibi endikasyonlarla invaziv koroner anjiyografi yapılmıştır. LMCA basısı, ardışık iki anjiyografik düzlemde referans distal LMCA segmentinde %50’nin üzerinde çap darlığı olarak tanımlanmıştır. Bulgular: LMCA basısı ve ses kısıklığı PH hastalarının sırasıyla %3.8 ve %4.3’ünde gösterilmiştir. Artan PA çapı daha kötü klinik, hemodinamik, laboratuvar ve ekokardiyografik parametrelerle anlamlı şekilde ilişkili bulundu. ROC eğrileri, 41 mm ve üzerindeki PA çap artışının ses kısıklığı için sınır değer olduğunu ortaya çıkardı (EAA: 0,834; duyarlılık %69, özgüllük %84, negatif öngörü değeri %98) ve PA çapının 35 mm ve üzerinde olması ise LMCA basısı için sınır değer olarak bulundu (EAA: 0,794; duyarlılık %89, özgüllük %58, negatif öngörü değeri %99). LMCA basısı için ses kısıklığının Odds oranı, %53,2 duyarlılık, %98,7 özgüllük, %59 pozitif ve %98 negatif öngörü değerleri ile 83,3 (%95 Güven Aralığı; 36,5 -190, P < 0,001) bulundu. Sonuç: Bu çalışmada şiddetli PH’lı hastalarda ses kısıklığının varlığı ile genişlemiş PA ile dıştan LMCA basısı olasılığı arasında yakın bir ilişki bulundu. Bu nedenle, ses kısıklığı şikayeti olan PH hastalarında LMCA basısı riski dikkate alınmalıdır
