AbstractObjective:(1) To investigate the incidence of laryngeal involvement in a large series of patients with pemphigus vulgaris, using endoscopic examination, (2) to describe the lesions, and (3) to establish a classification of laryngeal involvement in pemphigus vulgaris based on the location of the lesions.Study design:Prospective study.Methods:A total of 40 sequentially treated pemphigus vulgaris patients, diagnosed using clinical, histological and immunofluorescence criteria, were evaluated for laryngeal manifestations using endoscopic examination. The results were used to establish a graded classification of laryngeal involvement according to the location of the lesions.Results:Active laryngeal lesions (ulcers or blisters) were found in 16 patients (40 per cent). Of these, 37.5 per cent were classified as grade I, 20 per cent as grade II, 20 per cent as grade III and 17.5 per cent as grade IV.Conclusion:Laryngeal involvement is common in pemphigus vulgaris and must be considered at the point of diagnosis. Grade I lesions are the most frequent.

Abstract BACKGROUND There is lack of information on the role of excitatory and inhibitory neurotransmitters in the development of seizures in patients with lower grade gliomas. Increase of glutamate and downregulation of GABA have been suggested in preclinical models and human surgical samples to be associated with brain tumor-related epilepsy. MATERIAL AND METHODS We prospectively investigated with the use of magnetic resonance spectroscopy (MRS) the differences in the ratio of metabolites (glutamate/GABA, glutamate/creatine and GABA/creatine) in the peritumoral areas between patients with or without seizures in a series of lower grade gliomas. Tumors were classified according to WHO Classification of 2016 as follows:11 grade II IDH mutated and 1p/19q codeleted; 3 grade III IDH mutated and 1p/19q codeleted; 6 grade II IDH mutated and 1p/19q intact; 1 grade III IDH mutated and 1p/19q intact; 1 grade II IDH wild-type. Patients received surgery alone or followed by temozolomide chemotherapy according to the presence of risk factors. RESULTS At baseline evaluation, maximum glutamate/GABA values were significantly higher (p=0.023) in the peritumoral area of patients with seizures (1.008 ± 0.368) with respect to those without seizures (0.691 ± 0.170). No other metabolites ratio showed significant differences between the two groups. Similar results were obtained when analyzing the metabolites ratio in the examinations during the follow-up. In the cohort of patients with seizures (n.14) variations of metabolite ratios were not associated with tumor location, 1p/19q codeletion, use of AEDs, concomitant chemotherapy or seizure characteristics (type, duration, frequency). CONCLUSIONS The study is ongoing with the aim of analyzing further the correlations between ratio of metabolites and status of the tumor (stable vs progressive).

<p>The lesions of pemphigus in the larynx have been reported as case reports. However, the frequency with which it occurs is not known. The purpose of this study was to investigate the incidence of laryngeal involvement in pemphigus vulgaris and to examine the laryngeal lesions and the treatment in detail. The databases searched were PubMed, EMBASE, Cochrane Library and Google scholar. The involvement of larynx in patients with pemphigus vulgaris is common. The most common parts involved are epiglottis and arytenoids. This study indicates that laryngeal symptoms are common in pemphigus vulgaris. Laryngeal findings must be considered at the beginning of diagnosis for the better management and to prevent life threatening complications.</p>

Abstract Purpose: Conventional MRI based on contrast enhancement and T2/FLAIR is often not sufficient in differentiating grade II from grade III and grade III from grade IV diffuse gliomas. Here we assessed advanced metabolic imaging using two well characterized PET tracers, namely 18F-FDG and 11C-Methionine.Methods: In this prospective study, 39 patients were enrolled with diffuse gliomas of grades II, III or IV underwent dynamic [18F]-FDF-PET and [11C]-Methionine. The first minutes were taken into accountResults: The use of 11C- Methionine provided significant differences between the different histologic subgroups with a higher number of parameters than did the use of 18 F-FDG. The most informative parameter is T/Np (T/N at the peak of the first maximum) with 11C- Methionine.Conclusion: The study of the first minute passage of 18F-FDG and/or 11C- Methionine through the tumor and healthy tissues in brain gliomas could not only allow improving the identification of the different glioma grades, but also to shorten the time spent by the patients under the camera. In case of using one tracer, methionine still would be the best choice. Otherwise, the use of 18F-FDG and SUVр (SUV at the peak of the first maximum) would provide results likely comparable to methionine T/N index.

1051 Background: We evaluated the combination of a standard chemotherapy with panitumumab as neoadjuvant therapy of operable TNBC. Complete pathologic response (pCR) was the primary endpoint, with toxicity and biologic ancillary studies as secondary endpoints. Methods: Sixty patients with stage II-IIIA disease were prospectively included in this multicentre pilot study. Systemic therapy (ST) consisted of 4 cycles of FEC 100 (500/100/500 mg/m2) q.3 weeks followed by 4 cycles of T (100 mg/m2) q.3 weeks, in combination with panitumumab (9 mg/kg) for 8 cycles q.3 weeks. All patients underwent surgery at completion of ST. Paraffin-embedded samples and frozen samples have been systematically realised before and after neaodjuvant treatment in order to evalutate the biological profile of the tumor. Patients characteristics are : median age 50 ; median tumor size : 40 mm ; invasive ductal carcinoma : 96% ; Scarff-Bloom-Richardson Grade III : 70%, grade II : 30%, ki-67-positive : 100%, EGFR-positive : 78%, cytokeratine5-6-positive : 48% and p53-positive : 59%. Pathological response showed a pCR according to Sataloff’s classification of 52.38% and according to Chevallier’s classification of 46.52%. Skin toxicity was the main side-effect : Cutaneous toxicity grade IV : 5%, grade III : 30%, grade II : 20%. Neutropenia grade IV : 27% ; febrile neutropenia : 5%. Infection : 0%. Hand-foot syndrome grade III : 3.3%. Ungueal toxicity grade III : 1.6%, grade II : 20%. Results: We have tested the predictive value of ki-67, EGFR, cytokeratine 5-6 and p53. Only ki-67 is predictive of a pCR according to Chevallier’s classification (p=0.026), with a cut-off of 40% of positive cells (ROC curve): 62% of pCR if ki-67> 40% versus 23% if not (relative risk : 2.7). Low EGFR, high p53, and high cytokeratine 5-6 tended to be associated with poor reponse. No correlations were found between cutaneous toxicities and these biomarkers. The cutaneous toxicities were not predictive. Conclusions: HighKi-67 is predictive of more pCR. High EGFR, low p53 and low cytokeratine 5-6 tended to be associated with better response, but the data are not significant.

Histologic grade is an important determinant in clinical outcome of human osteosarcoma (OS). In this study, the histologic characteristics of primary and metastatic canine OS were evaluated using a new classification system. Histologic characteristics were classified in 166 primary and 34 metastatic canine OS. Prognostic variables for clinical outcome were determined using multivariate analysis. Most OS were histologically characterized by severe to extreme cellular pleomorphism, a variable number of mitoses, small to moderate amounts of matrix, a high percentage of tumor cells, and minimal to moderate amounts of necrosis. Tumor invasion into vessels was present in 117/152 (71%) tumors, and 12/50 (24%) of the regional lymph nodes had evidence of metastasis. Classification of the 166 tumors resulted in seven (4%) grade I, 34 (21%) grade II, and 125 (75%) grade III OS. In the multivariate analysis, histologic grade III OS and elevated pretreatment plasma alkaline phosphatase (AP) levels were independent predictors of clinical outcome. Dogs with high-grade tumors and elevated AP should be carefully evaluated for the presence of metastatic disease before starting adjunctive therapy protocols.

Background: Steroid injection is a proven treatment for trigger digits. The time taken for resolution of triggering following an injection is a question often asked by patients and one that has not been adequately addressed in existing literature. The aim of this study was to determine the time taken for triggering to resolve after a single steroid injection in patients presenting for the first time with a trigger digit. Methods: A prospective study was conducted in patients with first presentation of a grade II or grade III trigger digit(s) that received a steroid injection. Data with regards to age, gender, digit(s) involved, duration of symptoms, trigger grade, and presence of diabetes were collected. They were given a stamped addressed postcard with instructions to fill in the date that the triggering resolved and mail the postcard back to us. If the postcard was not received at three weeks, we contacted the patient by telephone to ask for the date of resolution of trigger. Results: 56 patients with 66 trigger digits were included in the study. 52 out of 66 digits (79%) had resolution of the trigger at one month. The mean duration for resolution of trigger was 8.8 days (range 1–30 days). Conclusions: Patients can be counselled that a steroid injection is effective in resolving the trigger in 79% of trigger digits presenting for the first time and that the mean time taken for resolution of triggering is 8.8 days. It is recommended to wait for at least one month before considering another injection or alternative treatments.

Glioma is one of the most common brain tumours among the diagnoses of existing brain tumours. Glioma grades are important factors that should be known in the treatment of brain tumours. In this study, the radiomic features of gliomas were analysed and glioma grades were classified by Gaussian Naive Bayes algorithm. Glioma tumours of 121 patients of Grade II and Grade III were examined. The glioma tumours were segmented with the Grow Cut Algorithm and the 3D feature of tumour magnetic resonance imaging images were obtained with the 3D Slicer programme. The obtained quantitative values were statistically analysed with Spearman and Mann–Whitney U tests and 21 features with statistically significant properties were selected from 107 features. The results showed that the best performing among the algorithms was Gaussian Naive Bayes algorithm with 80% accuracy. Machine learning and feature selection techniques can be used in the analysis of gliomas as well as pathological evaluations in glioma grading processes.   Keywords: Radiomics, glioma, naive bayes.

SummaryIn a prospective study, the outcome of surgical correction of medial patellar luxation of 70 stifle joints in 55 Pomeranian dogs was evaluated. Trochlear block recession alone was performed in 46 stifle joints, or in combination with tibial tuberosity transposition in 24 stifle joints in cases with grade II, III or IV medial patellar luxation. Additional procedures were performed to restore lateral and medial retinacular function. The recurrence of patellar luxation and the degree of lameness were evaluated up to at least 16 weeks after surgery. The overall recurrence rate was 10%. The outcome of surgery was considered good for grade II luxation with a 100% success rate. Recurrent medial patellar luxation was diagnosed in approximately 11% of dogs with grade III and in 36% of dogs with grade IV luxation. The postoperative lameness score decreased significantly in comparison with the preoperative score at four weeks and thereafter until the end of the study.

Analysis of 108 cases of Neonatal Tetanus by using a scoring system (Tjandra et al., 1974) revealed that 18 patients belonged to Grade I with a mortality rate of 5.6%; 43 belonged to Grade II with a mortality nate of 58.1%; and 47 belonged to Grade III with 91.5% mortality. The differences of mortality between the 3 groups are statistically significant. Mortality rate of 1973 was the lowest (50%) compared to that of 1972 (75%); 1974 (72.2%) and 1975 (61.4%). However, the number of patients belonging to Grade I in 1973 was the highest, 36.4%; whereas that of 1972 was 16.7%; 1974 was 11.1% and 1975 was 9.1 %. Classification of severity in Neonatal Tetanus is therefore, not only important for selecting a "treatment of choice" by comparing mortality rates of those having the same grade of severity, but may be also very useful in determining the method of treatment for different levels of severity.

Цель исследования. Разработка методов сопроводительной терапии для защиты нормальных органов и тканей, входящих в зону облучения. Методы. В исследование включено 112 больных раком шейки и тела матки после комбинированного или самостоятельного лучевого лечения с 2012 по 2016 гг. У 71 пациентки основной группы в качестве терапии сопровождения применяли гидрогель с деринатом и у 41 больной группы контроля - традиционные методы профилактики (масло оливковое, подсолнечное, метилурациловая мазь). Для профилактики эпителиита слизистой влагалища и шейки матки в основной группе использовали гидрогель в виде аппликаций с первого дня облучения. Для профилактики лучевого ректита гидрогель вводили в прямую кишку 1 раз в день с первого дня облучения. Инстилляции гидрогеля в мочевой пузырь начинали только при развитии первых признаков клинической картины цистита. Пациенткам контрольной группы для профилактики лучевых реакций проводились масляные, мазевые аппликации во влагалище, масляные микроклизмы в прямую кишку с первого дня облучения. Лечение лучевого цистита проводили с помощью растительных диуретиков, уросептиков. Результаты. Применение гидрогеля с деринатом позволило провести курс лучевой терапии без перерыва у 84,5% (60/71) больных, в контрольной группе - лишь у 48,8% (20/41). Лучевые циститы возникали в 2,5 раза реже (25,3% ± 3,3 против 63,4% ± 2,7, р<0,01). Анализ степени выраженности лучевого цистита по RTOG в двух группах показал, что у 75% больных основной группы наблюдалась I степень, у 25% - II степень, III и IV степени не отмечено, тогда как в контрольной группе лучевой цистит I степени развился у 44% пациенток, II - 40% и III - 16% больных. Применение гидрогеля снизило частоту лучевых ректитов в 2 раза (26,7% ± 3,3 против 53,7% ± 3,2 р<0,1).При использовании ежедневных аппликаций гидрогеля с деринатом со стороны слизистой оболочки влагалища и шейки матки преобладали эпителииты I степени (53,5%), II степень наблюдалась у 29,5% и III степень лучевой реакции - лишь в 16,9% случаев, IV степень реакции не отмечена. В контрольной группе эти показатели составили 26,8%, 24,3%, 31,7% и 17,2% соответственно. Разработаны цитологические критерии оценки течения лучевых реакций слизистой влагалища. Выделены три степени изменения цитограммы, которые коррелировали с клинической картиной. В основной группе лучевые изменения I степени зафиксированы в 4,5 раза чаще (52 ± 9,9% против 11,5 ± 6,3%, р<0,002), а III степень представлена в 3,8 раза реже, чем в контрольной группе (12 ± 6,5% против 46,1 ± 9,8%, р<0,003). Заключение. Применение гидрогелевого материала с деринатом в качестве препарата сопроводительной терапии во время курса облучения позволяет уменьшить частоту и степень выраженности лучевых повреждений со стороны слизистой влагалища, мочевого пузыря и прямой кишки, провести курс лучевой терапии без перерыва и улучшить качество жизни пациенток. Objective. Development of methods for accompanying therapy to protect normal organs and tissues in the irradiation zone. Method. The study included 112 patients with cervical and endometrial cancer after combined or independent radiotherapy from 2012 to 2016. In 71 female patients of the main group, Derinat with hydrogel was applied as a supportive therapy and in 41 patients of the control group, conventional prevention methods (olive oil, sunflower oil, methyluracyl ointment) were applied. For prevention of vaginal mucosal and cervical epitheliitis in the main group, hydrogel was used as applications from the first radiation day. For prevention of radiation proctitis, hydrogel was injected into the rectum once daily from the first radiation day. Hydrogel instillations into the bladder were started only with the first clinical signs of cystitis. For prevention of radiation reactions, vaginal oil and ointment and rectal oil micro-enema were administered to patients of the control group from the first day of irradiation. Radiation cystitis was treated with vegetable diuretics and uroseptic drugs. Results. Using the hydrogel with Derinat allowed to administer a course of radiotherapy without interruption in 84.5% (60/71) of patients and only in 48.8% (20/41) in the control group. Radiation cystitis occurred 60% less frequently (25.3% ± 3.3 versus 63.4% ± 2.7, p <0.01). Analysis of radiation cystitis severity in two groups (according to RTOG) showed that 75% of patients in the main group had grade I and 25% had grade II. Grade III and grade IV did not occur. At the same time, in the control group, grade I radiation cystitis developed in 44% of patients, grade II - in 40%, and grade III - in 16% of patients. The hydrogel treatment halved the frequency of radiation proctitis (26.7% ± 3.3 vs. 53.7% ± 3.2 p <0.1). With daily application of the hydrogel with Derinat, grade I epitheliitis (53.5%) predominated in vaginal and cervical mucosa, grade II was observed in 29.5%, and grade III radiation reaction - only in 16.9% of cases; grade IV reaction was not observed. In the control group, these proportions were 26.8%, 24.3%, 31.7%, and 17.2%, respectively. Cytological criteria were developed to evaluate the course of radiation reactions in the vaginal mucosa. Three degrees of change in the cytogram were identified, which correlated with clinical picture. In the main group, incidence of grade I radiation-induced changes was increased by more than 350% (52 ± 9.9% vs. 11.5 ± 6.3%, p <0.002), and incidence of grade III was decreased by more than 70% compared to the control group (12 ± 6.5% vs. 46.1 ± 9.8%, p <0.003). Conclusion. Using the hydrogel material with Derinat as an accompanying therapy during the course of irradiation allows to reduce frequency and severity of radiation injuries of the vaginal mucosa, bladder, and rectum, administer an uninterrupted course of radiotherapy, and improve the quality of life of patients.
