lways necessary to identify the other associated anomalies in addition to the primary diagnosis since these features may direct to a syndromic diagnosis.

Acquired hypothyroidism is a relatively common endocrine disorder among children and early recognition is important to prevent serious complications like Van Wyk-Grumbach syndrome. Sexual precocity with delayed bone age and stunting should direct our minds toward this unique diagnosis. It is always necessary to identify the other associated anomalies in addition to the primary diagnosis since these features may direct to a syndromic diagnosis.To avoid possible confusions to the readers, we provide further explanations for the eq.

The current therapeutic strategies in asthmatic patients are based on controlling the activity of type 2 T helper lymphocytes in the pulmonary tissue. However, most of the available therapies are symptomatic and expensive and with diverse side outcomes in which the interruption of these modalities contributes to the relapse of asthmatic symptoms. Up to date, different reports highlighted the advantages and beneficial outcomes regarding the transplantation of different stem cell sources, and relevant products from for the diseases' alleviation and restoration of injured sites. However, efforts to better understand by which these cells elicit therapeutic effects are already underway. The precise understanding of these mechanisms will help us to translate stem cells into the clinical setting. In this review article, we described current knowledge and future perspectives related to the therapeutic application of stem cell-based therapy in animal models of asthma, with emphasis on the underlying therapeutic mechanisms.

A combination of intestinal malrotation and distal cholangiocarcinoma is considered a rare condition and poses some difficulties in surgical management. We present a case of a patient with asymptomatic nonrotation of the midgut with a concomitant distal cholangiocarcinoma who underwent successful pancreaticoduodenectomy.

A 52-year-old Sudanese man presented to our hospital with progressive painless jaundice associated with dark urine, pale stool, and itching for the last 2 months. He had no other complaint or significant previous medical history apart from being an ex-smoker. His clinical examination revealed a palpable gallbladder and scratch mark. His other systems were unremarkable. His blood test results showed a normal complete blood count, elevated total bilirubin (mainly direct bilirubin), elevated alkaline phosphatase, and normal cancer antigen 19-9 and carcinoembryonic antigen. Ultrasound, computed tomography of the abdomen, and magnetic resonance cholangiopancreatography showed a dilated intrahejunum 10 cm below the uncinate process of pancreas, and modified pancreaticoduodenectomy were performed, and anastomoses were performed in the standard fashion. The patient had an uneventful postoperative course, started oral feeding after 5 days, and discharged to home on day 10 for regular follow-up. Histopathology confirmed distal cholangiocarcinoma, and the patient was referred for further oncological management.

Pancreaticoduodenectomy can be safely performed in patients with intestinal malrotation with some modifications of the standard approach. Meticulous dissection after preoperative identification of vascular anomaly and a lateral approach are of great help to reduce morbidity.

To establish pharmacokinetic parameters and a radiomics model based on dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) for predicting sentinel lymph node (SLN) metastasis in patients with breast cancer.

A total of 164 breast cancer patients confirmed by pathology were prospectively enrolled from December 2017 to May 2018, and underwent DCE-MRI before surgery. Pharmacokinetic parameters and radiomics features were derived from DCE-MRI data. Least absolute shrinkage and selection operator (LASSO) regression method was used to select features, which were then utilized to construct three classification models, namely, the pharmacokinetic parameters model, the radiomics model, and the combined model. These models were built through the logistic regression method by using 10-fold cross validation strategy and were evaluated on the basis of the receiver operating characteristics (ROC) curve. An independent validation dataset was used to confirm the discriminatory power of the models.

Seven radiomics features were selected by LASSO logistic regression. The radiomics model, the pharmacokinetic parameters model, and the combined model yielded area under the curve (AUC) values of 0.81 (95% confidence interval [CI] 0.72 to 0.89), 0.77 (95% CI 0.68 to 0.86), and 0.80 (95% CI 0.72 to 0.89), respectively, for the training cohort and 0.74 (95% CI 0.59 to 0.89), 0.74 (95% CI 0.59 to 0.90), and 0.76 (95% CI 0.61 to 0.91), respectively, for the validation cohort. The combined model showed the best performance for the preoperative evaluation of SLN metastasis in breast cancer.

The model incorporating radiomics features and pharmacokinetic parameters can be conveniently used for the individualized preoperative prediction of SLN metastasis in patients with breast cancer.

Lung disease is a leading cause of morbidity and mortality. A breach in the lung alveolar-epithelial barrier and impairment in lung function are hallmarks of acute and chronic pulmonary illness. Tunicamycin inhibitor This review is part two of our previous work. In part 1, we demonstrated that CdM is as effective as MSCs in modulating inflammation. Herein, we investigated the effects of mesenchymal stromal cell (MSC)-conditioned media (CdM) on (i) lung architecture/function in animal models mimicking human lung disease, and (ii) performed a head-to-head comparison of CdM to MSCs.

Adhering to the animal Systematic Review Centre for Laboratory animal Experimentation protocol, we conducted a search of English articles in five medical databases. Two independent investigators collected information regarding lung alveolarization, vasculogenesis, permeability, histologic injury, compliance, and measures of right ventricular hypertrophy and right pulmonary pressure. Meta-analysis was performed to generate random effect size using standardized mean difference with 95% confidence interval.
