Lymph Node Ultrasound

Melanoma is an aggressive tumour, resistant to treatment, derived from melanocytes, with an increasing incidence in the last years in the majority of countries. The most important prognostic factor in the initial stages (I/II) is the presence of metastases at the level of lymph nodes. Ultrasound (US) is a non-invasive method, used in the pre- and post-operative node evaluation due to its high availability, the reduced cost and easy reproducibility. TheUSaccuracy is however dependent on operator expertise. The present article proposes a presentation of the US role in the evaluation of lymph nodes in melanoma patients.

The aim of the study was to evaluate the role of virtual bronchoscopy (VB) in traumatic rupture of the main bronchus Material and methods. Тhe data of virtual bronchoscopy of multispiral computed tomography (MSCT) with multiplanar and 3D reconstructions of 10 patients with traumatic separation of the main bronchus were analyzed. MSCT was carried out by the computer tomograph AquilionONE (320-slice) according to the previously described technique. Results of the study. VB MSCT allowed to determine the presence of a complete or partial rupture of the main bronchus, its distance to the bifurcation of the trachea, the state of the collapsed lung, the presence of fluid in the hemithorax, secondary changes in the bone structures of the chest. The World Bank played an important role in monitoring the adequacy of reconstructive measures on the damaged bronchus, excluding the occurrence of postoperative stenosis. The conclusion. Virtual bronchoscopy of multispiral computed tomography with the capabilities of multiplanar and volumetric reconstructions, postprocessing image processing is an optimal non-invasive method for determining the traumatic lesion of the main bronchi and monitoring the success of the reconstructive surgical manual.

Abstract. To investigate the role of gonadotropins in postnatal testicular activation, testosterone responsiveness to human chorionic gonadotropin was studied in 11 male infants (aged 5-180 days). The boys were given a single im injection of 5000 IU/1.7m2 hCG, and serum and salivary testosterone responses were then measured for 7 days. The results were compared with the serum testosterone responses of 8 older prepubertal boys (aged 1.7-10.4 years) studied with the same protocol. The mean (±sem) basal serum testosterone levels were 2.67±1.27 nmol/l in the infants and 0.09±0.02 nmol/l in the prepubertal boys (p<0.05). Both groups gave a significant response to hCG stimulation (p<0.001, ANOVA, one-way). The stimulated concentrations of serum testosterone were higher in the infants than in the prepubertal boys (p<0.001). The mean basal level of salivary testosterone was 30.5 ±7.0 and the mean maximal level was 97± 10.3 pmol/l in the infants (p<0.001). No age-related changes were observed in either basal or hCG-stimulated levels. In infants the mean (±sem) maximal hCG-stimulated increase was 25 ± 10-fold in serum and 8±4-fold in saliva (p=0.13). A clear stimulatory effect of hCG on testicular testosterone production was found, suggesting that the postnatal increase in serum testosterone concentration in male infants is gonadotropin-mediated. Salivary testosterone concentrations can be increased by hCG, indicating that measurements of salivary testosterone may provide an optional, non-invasive method for assessing gonadal function in children.

Bronchiolitis is one of the commonest reasons for paediatric critical care admission in infants. This chapter explores the epidemiology of bronchiolitis, risk factors for severe illness, and various management strategies. In particular, this chapter explores the assessment of a deteriorating child with bronchiolitis and escalation strategies, including high-flow nasal cannula oxygen and non-invasive respiratory support progressing to invasive mechanical ventilation. This chapter includes a review of the literature related to supportive therapies such as nebulized saline, bronchodilators, and saturation targets. Indications for intubation, various intensive care strategies, and their relative effectiveness are also discussed. The role of respiratory extracorporeal membrane oxygenation in bronchiolitis is also explored.

Dermatoscopy is a valuable auxiliary non−invasive method used in the diagnosis of inflammatory, parasitic and viral skin diseases. Treatment of dermatoses is based on the results of analysis of melanin, follicular−horny and vascular components. Diagnosis begins with polarized dermatoscopy and then progresses to non−polarized using immersion fluid. At dermatoscopic inspection of a psoriatic plaque the point vessels evenly distributed along all the surface (a symptom of "scattered red pepper") are noted. Eczema is characterized by focal accumulation of blood vessels in the form of dots, peeling, yellowish crusts. Examination of discoid lupus erythematosus foci often reveals individual linear or branched vessels, their location is random. Red herpes zoster is dermatoscopically characterized by vascular structures in the form of large granular horny plugs of whitish color with a pearly sheen. The most informative is dermatoscopy in the differential diagnosis of erythematous form of rosacea and seborrheic dermatitis. On the erythematous background, dilated vessels around the sebaceous hair follicles, large vascular polygons formed from vessels thicker than in healthy skin and seborrheic dermatitis are found. At inspection of the fresh centers of a sclero−atrophic lichen diffuse unstructured zones of white color with a peripheral erythematous corolla and with numerous light comedic structures on a surface are visualized. At dermatoscopy of the Little − Lassueur syndrome in follicular papules on skin gray, violet points located in the form of a circle are noted. Dermatoscopy is increasingly used in dermatology, especially in the differential diagnosis of dermatoses of inflammatory and parasitic nature.

Abstract Mortality from colorectal cancer is reduced through screening and early detection; moreover, removal of neoplastic lesions can reduce cancer incidence. While understanding of the risk factors, pathogenesis, and precursor lesions of colorectal cancer has advanced, the cause of the recent increase in cancer among young adults is largely unknown. Multiple invasive, semi- and non-invasive screening modalities have emerged over the past decade. The current emphasis on quality of colonoscopy has improved the effectiveness of screening and prevention, and the role of new technologies in detection of neoplasia, such as artificial intelligence, is rapidly emerging. The overall screening rates in the US, however, are suboptimal, and few interventions have been shown to increase screening uptake. This review provides an overview of colorectal cancer, the current status of screening efforts, and the tools available to reduce mortality from colorectal cancer.

Renal Tubular

The kidney function can be assessed by a number of methods. The urinary excretion of enzymes, in particular N-acetyl-β-D-glucosaminidase (NAG), is considered a relatively simple, cheap, fast and non-invasive method in the detection and follow-up of renal tubular function under various conditions. The determination of urinary NAG provides a very sensitive and reliable indicator of renal damage, such as injury or dysfunction due to diabetes mellitus, nephrotic syndrome, inflammation, vesicoureteral reflux, urinary tract infection, hypercalciuria, urolithiasis, nephrocalcinosis, perinatal asphyxia, hypoxia, hypertension, heavy metals poisoning, treatment with aminoglycosides, valproate, or other nephrotoxic drugs. This paper gives an overview of the current use of urinary NAG in the detection of renal injury.
