Ultrasound Assessment

Aim of the Study. The aim of the study was to conduct an ultrasound (US) assessment of changes in fingernails in psoriatic patients with nail involvement. Material. A total of 69 patients with psoriatic changes in nails participated in the study, including 38 patients with psoriasis (Ps) and 31 with psoriatic arthritis (PsA) and 30 people in the control group. A total of 988 nails were examined. Results. The thickness of the nail plate, nail bed, and matrix as shown in an ultrasound examination increased with the mNAPSI index (r=0.328, p=0.021; r=0.219, p=0.036; and r=0.422, p=0.011, respectively). The thickness of nail plate, bed, and matrix in patients with onycholysis and hyperkeratosis-type changes (concomitant or present separately) was significantly greater than when only pitting-type changes occurred (p=0.007, p=0.035, and p=0.023, respectively). An examination of nails with only pitting-type changes showed an increase in the matrix thickness compared to the control group (p=0.018). The focal hyperechoic involvement of the dorsal plate (80%) was the change most often observed in an US examination in Ps patients, whereas loosening of the borders of the ventral plate was most often observed in PsA patients. The thickness of nail bed in PsA patients increased with the duration of arthritis (r=0.399, p=0.022) and was correlated with the number of swollen digits (r=0.278, p=0.041). Conclusions. The findings of this study may indicate an association of an inflammation in the nail bed with PsA development. Apart from a direct assessment of the described morphological changes of nails, a US examination could prove useful in an assessment of intensity of a local inflammation as a prognostic factor for PsA development.

Retinoid Treatment

The study aimed to evaluate the effect of retinoid treatment on the morphological changes in the nail apparatus in patients with nail psoriasis. Material and methods: 41 patients aged 32 to 64 with nail psoriasis, without clinical signs of psoriatic arthritis, started on acitretin 0.6 to 0.8 mg kg b.w./d, for six months and 28 people in the control group were included in the study. Both groups had ultrasound examination of fingernails and digital extensor tendon in the distal interphalangeal joints. In psoriatic patients, US examination was conducted before starting the treatment and after six months. A total of 685 nails were examined. Results: After six months of treatment, there was a reduction in the thickness of the nail bed and nail matrix (p = 0.046 and p = 0.031, respectively). The thickness of the nail plates decreased, although it was statistically insignificant (p = 0.059) and it was higher than in the control group (p = 0.034). The reduced severity of clinical nail changes after six months of retinoid treatment did not correlate with the reduction in extensor tendon thickness in any group of patients. Conclusions: In patients with nail psoriasis, acitretin treatment resulted in a rapid decrease in the thickness of the nail bed and matrix, but it did not affect the thickness of the nail plate after six months. There was no effect of acitretin on the digital extensor tendon thickness or the increased blood supply to the tendon area. The results of the study may indicate the usefulness of ultrasound nail examinations in patients with nail psoriasis not only to assess the advancement of morphological changes and response to treatment, but also to choose the potential treatment.

Objective. To study echographic and hemodynamic features of the nail plate and surrounding tissues in patients with different clinical variants of onychomycosis of the feet using an ultrasonic transducer with a scanning frequency of 15–22 MHz and on this basis to define the most significant ultrasound signs of this pathology. Patients and methods. 52 patients with onychomycosis of the feet (the main group) and 20 volunteers (the control group) without a fungal nail infection were examined. Ultrasonic scanning was performed using a transducer with a frequency of 15–22 MHz. The sonographic structure and sizes of nail components were registered. Features of blood supply were studied in the area of the nail bed and root using duplex scanning. Results. In patients with onychomycosis in the nail plate, the change in lateral dimensions of its layers was revealed. Structural imperfection and uneven increase in the thickness of intermediate layer of the nail plate, misalignment of ventral and dorsal layers were detected. Discontinuity and blurring of the structure of the ventral layer were observed in this context. In patients with subungual onychomycosis, a thickening of the nail bed and change in its acoustic properties were revealed. When the nail root was involved in the pathological process, an increase in echogenicity and blurring of boundaries in the matrix area were recorded. Decreased value of hemodynamic indices and smoothing of the dopplerographic curve, in comparison with the control group, were observed. Conclusion. Detected ultrasound signs broaden the understanding of changes in the nail echostructure and hemodynamics indices under the influence of a fungal infection, and can be useful in comprehensive diagnostics of onychomycosis of the feet. Key words: sonographic and hemodynamic signs of onychomycosis, nail ultrasonography

Abstract Background Nail psoriasis occurs frequently in patients with psoriatic disease, it can lead to functional impairment, pain, discomfort, decreased quality of life and can also be a predictor for the development of arthritis. Early recognition of this condition can provide early and effective treatment and prevent structural impairment. This study aims to identify nail ultrasonographic characteristics in three groups: psoriasis (PsO), psoriatic arthritis (PsA) and controls patients, to determine if the ultrasonography (US) can identify early signs of nail psoriatic impairment or local inflammation. We conducted nail US to determine nail matrix resistance index (NMRI), nail bed resistance index (NBRI), and power Doppler (PD) and grayscale (GS) parameters in these 3 groups. Methods Single-center, cross-sectional study. GS, PD, and spectral doppler images of bilateral 2nd and 3rd fingernails were acquired from 35 PsO, 31 PsA, and 35 controls patients. An US equipment with an 18 MHz linear transducer for GS and 8.0 MHz for PD was used. PD, NMRI, NBRI, nail plate thickness (NPT), nail bed thickness (NBT), nail matrix thickness (NMT), and morphostructural characteristics of the trilaminar structure (TS) were evaluated in saved images, blind. Results Mean NMRI and NBRI did not differ between groups. Linear regression analysis detected no relationships between PsO or PsA and NMRI or NBRI. Nail PD grade did not differ between groups. Type I and IV TS changes were more frequent in PsO; types II and III changes were more frequent in PsA (p < 0.001). NPT was greater in PsA and PsO groups than controls: PsA 0.73 ± 0.14 mm, PsO 0.72 ± 0.15 mm, Controls 0.67 ± 0.10 mm (p = 0.001). Conclusion Echographic TS characteristics of the nail plate and NPT evaluated by GS are useful and can distinguish PsO and PsA nails from controls. NMRI, NBRI, and US nail microcirculation parameters could not distinguish psoriatic nails.

Abstract Background Using remineralizing agents during and after bleaching procedures could maintain enamel surface, decreasing its erosive susceptibility. This study evaluated the efficacy of an in-office and at-home bleaching materials with amorphous calcium phosphate (ACP) on the susceptibility of the enamel to erosion. Forty-five bovine specimens were separated into three groups. Group A: no bleaching (control). Group B: Zoom 2 bleaching followed by ACP application. Group C: Nite White ACP. All specimens in all groups were subjected to an erosive challenge for five days. Using Energy Dispersive X-ray all specimens were subjected to elemental analysis and were examined for morphological changes under Scanning Electron Microscope (SEM). Results Group B showed the highest mean calcium, phosphorus and sodium weight percent (wt%). Both Groups B and C showed statistically significant difference. While, there was no statistically significant difference between both Groups A and B.The sodium mean wt% showed a statistically significant difference in all groups. The magnesium mean wt% showed no statistically significant difference in all groups. SEM photomicrograph revealed hollowing of prism cores with intact prisms peripheries for group A. Group B showed relativity smooth surface with minor pores, while Group C showed an increase in the depth of surface irregularities and depressions. Conclusions Enamel susceptibility to erosion after bleaching procedure was material dependent. Zoom 2 bleaching agent followed by ACP application did not increase the susceptibility of the enamel surface to erosion. Adding ACP to Nite White bleaching agent had no benefit on reducing enamel susceptibility to erosion.

Background: Although there are various surgical methods for subungual glomus tumor treatment, there is no consensus on the optimal surgical approach. Methods: We analyzed the outcomes of 15 patients treated with partial nail plate excision technique. The medial or lateral section of the nail plate was excised longitudinally based on the tumor location. After incision of the nail bed and tumor removal, the matrix was repaired carefully. Results: In this study, 15 people, including 11 men and four women, were studied. The mean onset of symptoms until diagnosis was 88 months. In the postoperative evaluation, the mean follow-up was 20 months. Two patients had recurrent tumors, and one had postoperative nail deformity. Conclusion: Meticulous nail bed repair and complete tumor excision are key treatment points needed to prevent nail deformity and recurrence.

An urgent issue of modern morphology is establishing a number of patterns of morphological changes and reactivity of connective tissue components of lungs in case of experimental sensitization with allergens. The aim is to estimate morphological features of histogenic differon cells in connective tissue of guinea pigs’ lungs after sensitization with ovalbumin. Materials and methods. Using morphometric and histological method, we have estimated the lung connective tissue of 48 male guinea pigs with experimental ovalbumin-induced allergic inflammation, simulated by subcutaneous sensitization and aeroallergization with ovalbumin. The number of fibrocytes, fibroblasts per 5000 μm2 and their ratio – fibroblast/fibrocyte coefficient were determined. Results. We have established the regularity of morphological changes dynamics in the cellular elements of pulmonary connective tissue. Experimental sensitization and inhalated allergization with ovalbumin leads to a statistically significant increase in the average number of fibroblasts and fibrocytes throughout the observation period in all experimental groups. It has been proved that the dynamics of cells has a multidirectional character, demonstrated by indicators of the fibroblast/fibrocyte coefficient, which shows the disproportion in the fibroblast/fibrocyte ratio and proves the tendency to the development of fibrosis in guinea pigs’ pulmonary connective tissue in case of experimental sensitization with ovalbumin. Conclusions. A gradual increase in the number of fibrocytes, against the background of a decrease in the number of fibroblasts is observed from the 23rd day to the completion of experimental sensitization with ovalbumin in the lungs of guinea pigs, compared with control group. A decrease of fibroblast/fibrocyte coefficient from 1.37 ± 0.03 in the early period to 0.82 ± 0.03 in the late period of the allergic inflammation demonstrates multidirectional nature of the dynamics in the number of connective tissue cells and indicates a tendency towards the development of fibrosis in pulmonary connective tissue.

The aim of the study: to study the efficacy and safety of use Mastofemin in the treatment of various forms of mastitis in women of reproductive age. Materials and methods. The study included 62 women of reproductive age (mean age of 33.5±2.3 years) who were screened in the Kiev city center reproductive and perinatal medicine. Women were divided into 2 groups. The first (main) group consisted of 32 patients who received the proposed treatment using herbal remedies Mastofemin 1 capsule 2 times per day for 3 months; 30 patients of the second (control) group were under observation and received no treatment. These groups were representative and homogeneous on age, clinical symptoms and sonographic characteristics. The clinical method included evaluation of complaints of patients, anamnesis, presence of concomitant gynecologic pathology, inspection, palpation of the lymph nodes and the breast and obtaining a discharge from the nipples to conduct cytological examination, which allowed excluding from the study women with suspected malignancy of the process. All the patients were performed ultrasound examination of the breast. The review was supplemented with vaginal gynecological examination and ultrasound examination of small pelvis organs to assess the condition of the uterus and its appendages, the diagnosis of gynecological diseases. Results. Summarizing obtained in this study results one should stress the positive long-term effect of applying Mastofemin for the treatment of proliferative changes of the breast in women of reproductive age. This is manifested by a decrease in the intensity of clinical signs of mastitis, consistent with the results of sonographic control. Established positive dynamics in the treatment of cystic mastitis, dectective and when combined cystic mastopathy with dectective. In the control group of patients for a given observation period (6 months) no significant changes in clinical signs of mastitis and sonographic characteristics. Regression of disease has not occurred in any of the patients, in 2 patients increased sensitivity of the breast after 6 months moved to the soreness. Sonographic characteristics of mastitis during the observation period did not change. Thus, the use of Mastofemin aimed at pathogenetic treatment of mastitis and prevention of breast cancer. Conclusion. Application of Mastofemin during the treatment of mastitis in women of reproductive age significantly improves the clinical condition of patients; reduce the subjective and objective symptoms of the disease. The positive effect of the treatment with Mastofemin proved in the case of the treatment of sonographic following forms of mastitis: cystic mastopathy, cystic mastopathy with dectectasy. Mastofemin may be the drug of choice for complex conservative monotherapy in women of reproductive age with proliferative changes in the breast, and can also be used as part of complex treatment in patients with diffuse changes of the breast when combined with hyperplastic processes of the myometrium and endometrium.

In this work, we studied the pharmacological activity of zinc and magnesium salts of 2-aminoethanesulfonic acid in white non-linear male rats with amyotrophic lateral sclerosis, which was modeled by neurotoxicantsimplication into the pelvic part of spinal cord. After the reproduction of the pathology in animals, the indices of motor activity were recorded in the Rotarod test, and morphological studies of spinal cord sections stained according to Nisl in the Belshovsky modification were carried out. It was shown that the magnesium salt of 2-aminoethanesulfonic acid (compound LHT-317) to a greater extent reduces the development of motor disorders in experimental animals compared with the control group on the 4th day of observation. The course of intravenous administration of the studied compounds of 2-aminoethanesulfonic acid did not inhibit morphological changes in the spinal cord that develop in degenerative-dystrophic pathology of the central nervous system: connections. Moreover, if, against the background of treatment with zinc salt, the total area of motor zones in animals of the experimental group exceeded that of control rats, then the number of motoneurons did not differ from the control.

According to the Tambovagrochemcenter data, zinc deficiency in animal rations exceeds 33%. To de-termine the efficiency of ration additives 3 groups of calves were formed, one of which was control and received regular feed, first test group received additional Zinc Sulphate, and second test group received additional Zinc Bioplex. To assess the results, we take into account the following values: chemical com-position and nutritional values of the feed, body mass value, amount of immunoglobulins in blood, bio-chemical and hematological values of blood, morphological values of fur and skin. Noticeable results were achieved in 4 months, with first and second test groups receiving accordingly 3,15% and 6,13% more body mass increase over the control group. A tendency towards higher albumin concentration in both test groups was noted, and calves of the second test group had higher amounts of hemoglobin and higher concentrations of it per erythrocyte. In samples of epidermis and hairs of the second test group the papillary layer was well developed, with the amount of hair and hair follicles exceeding 7 in the field of view, with the thickness of hairs being at least 70 μm. Inner papilla of hair contained 6 to 8 layers of hair, thickness of awn hairs reaching 80-90 μm, down hairs reaching 40 μm, with the hair cortex making up more than 80% of the hair thickness. Thus, introducing zinc salts and chelated zinc compounds to the milk-fed calves’ ration, has resulted in monetary profit increases over the control group by 255,0 and 612,0 roubles accordingly. By all researched values, the highest results were reached from adding zinc bioplex with approximately 360 mg added per animal for the entire duration of the growth process.
