Dynamics of cell population structure in liver biopsy of the patients with chronic hepatitis viral infection

The cell population analysis of liver biopsies from the patients with both chronic hepatitis, chronic viral hepatitis C (HCV) and chronic viral hepatitis B (HBV) included the comparative evaluation of the specific part of non-parenchymal elements, analysis of the liver plates and sinusoids areas, the cell population of liver plates and sinusoids, the caryometric description of different types of cells. The essential difference of similar quantitative indexes in the biopsy specimens of patients with HCV and НВV was revealed and discussed. In total, the quantitative analysis of cell population structure in liver biopsies during the course of chronic hepatitis, especially in the case of defective biopsies, could be used for diagnostics and prognoses by expert evaluation

Comparison of Post-injection Site Pain Between Technetium Sulfur Colloid and Technetium Tilmanocept in Breast Cancer Patients Undergoing Sentinel Lymph Node Biopsy

BACKGROUND: No prior studies have examined injection pain associated with Technetium-99m Tilmanocept (TcTM). METHODS: This was a randomized, double-blinded study comparing postinjection site pain between filtered Technetium Sulfur Colloid (fTcSC) and TcTM in breast cancer lymphoscintigraphy. Pain was evaluated with a visual analogue scale (VAS) (0–100 mm) and the short-form McGill Pain Questionnaire (SF-MPQ). The primary endpoint was mean difference in VAS scores at 1-min postinjection between fTcSC and TcTM. Secondary endpoints included a comparison of SF-MPQ scores between the groups at 5 min postinjection and construction of a linear mixed effects model to evaluate the changes in pain during the 5-min postinjection period. RESULTS: Fifty-two patients underwent injection (27-fTcSC, 25-TcTM). At 1-min postinjection, patients who received fTcSC experienced a mean change in pain of 16.8 mm (standard deviation (SD) 19.5) compared with 0.2 mm (SD 7.3) in TcTM (p = 0.0002). At 5 min postinjection, the mean total score on the SF-MPQ was 2.8 (SD 3.0) for fTcSC versus 2.1 (SD 2.5) for TcTM (p = 0.36). In the mixed effects model, injection agent (p < 0.001), time (p < 0.001) and their interaction (p < 0.001) were associated with change in pain during the 5-min postinjection period. The model found fTcSC resulted in significantly more pain of 15.2 mm (p < 0.001), 11.3 mm (p = 0.001), and 7.5 mm (p = 0.013) at 1, 2, and 3 min postinjection, respectively. CONCLUSIONS: Injection with fTcSC causes significantly more pain during the first 3 min postinjection compared with TcTM in women undergoing lymphoscintigraphy for breast cancer

Диагностические и прогностические лабораторные критерии развития сепсиса при гнойно-воспалительных заболеваниях мягких тканей

Objective. Identification of laboratory parameters that are used in routine practice and can serve as diagnostic and prognostic criteria for the development of sepsis and its outcomes in patients with purulent-inflammatory diseases of soft tissues.Materials and methods. The study included 48 patients with purulent-inflammatory diseases of soft tissues. Recorded the occurrence of such clinical events as the development of sepsis or septic shock, intensive therapy, death or recovery and discharge from the hospital. For the diagnosis of sepsis, a SOFA (Sepsis-related organ failure assessment score) ³ 2 points was used. Patients were divided into subgroups according to the number of points according to the SOFA scale, intensive care and depending on the outcome of the disease: Subgroup 1 – 26 patients with sepsis (SOFA ³ 2 points) and 22 patients with systemic inflammatory response syndrome (SIRS) and SOFA &lt;2 points; 2nd subgroup – 12 people who underwent intensive therapy and 36 people without it; 3rd subgroup – 7 patients with a fatal outcome and 41 patients with a favorable outcome.Results. In patients with sepsis, albumin concentration was 24,07 g / l in median versus 34,65 g / l in the control group of patients with SOFA &lt;2 points (p &lt;0,01); glucose -7,82 mmol / l and 5,15 mmol / l (p &lt;0,01); sodium concentration of 133 mmol / li 139 mmol / l (p &lt;0,01). The values of the international normalized ratio (INR) amounted to a median of 1,29 and 1,04 (p &lt;0,01); activated partial thromboplastin time -36,20 seconds and 31,50 seconds (p &lt;0,01). In the subgroup of patients for whom intensive therapy was required, the concentration of albumin was 22,34 g / l by median versus 30,10 g / l (p &lt;0,01); urea – 15,50 mmol / l versus 6,00 mmol / l (p &lt;0,05), glucose – 9,61 mmol / l against 5,80 mmol / l (p &lt;0,05), lactate dehydrogenase-644,00 U / l and 426,00 U / l (p &lt;0,05); INR – 1,35 against 1,05 (p &lt;0,05). The aver-age total protein concentration is 47,80 g / l versus 57,90 g / l (p &lt;0,01). The average albumin is 22,34 g / l versus 28,50 g / l (p &lt;0,05). The glucose concentration among patients with a fatal outcome was 12,00 mmol / l in median versus 5,95 mmol / l (p &lt;0,01); urea – 23,22 mmol / l versus 6,00 mmol / l (p &lt;0,01). The incidence of lethal disease was statistically significantly higher in patients with a total protein level of less than 52 g / l 5,96 times (RR = 5,96, 95% CI 1,32 – 26,89), glucose more than 11 mmol / l – 7,00 times (OR = 7,00, 95% CI 1,25 – 39,15), urea more than 20 mmol / l – 7,05 times (RR = 7,05, 95% CI 2,00 – 24,85).Conclusion. Routine laboratory indicators as the level of total protein, albumin, glucose, sodium and urea, as well as indicators of the blood coagulation system (INR and APTT), can serve as diagnostic and prognostic criteria for the development of sepsis and its outcomes in patients with purulentinflammatory diseases. soft tissue.Цель: выявление лабораторных показателей, которые используются в рутинной практике и могут служить диагностическими и прогностическими критериями развития сепсиса и его исходов у пациентов с гнойно-воспалительными заболеваниями мягких тканей.Материалы и методы. В исследование включено 48 пациентов с гнойно-воспалительными заболеваниями мягких тканей. Проводили учет наступления таких клинических событий, как развитие сепсиса или септического шока, проведение интенсивной терапии, летальный исход или выздоровление и выписка из стационара. Для постановки диагноза «сепсис» применяли шкалу SOFA (Sepsis-related organ failure assessment score) ³ 2 баллов.

В подгруппе пациентов, которым потребовалось проведение интенсивной терапии, концентрации альбумина составили по медиане 22,34 г/л против 30,10 г/л (p&lt; 0,01); мочевины – 15,50 ммоль/л против 6,00 ммоль/л (p&lt; 0,05), глюкозы– 9,61 ммоль/лпротив 5,80 ммоль/л(p&lt; 0,05), лактатдегидрогеназы – 644,00 Ед/л и 426,00 Ед/л (p&lt; 0,05); МНО – 1,35 против 1,05 (p&lt; 0,05). Средняя концентрация общего белка – 47,80 г/л против 57,90 г/л (p &lt; 0,01). Средние показатели альбумина – 22,34 г/л против 28,50 г/л (p &lt; 0,05). Концентрация глюкозы среди пациентов с летальным исходом составила по медиане 12,00 ммоль/л против 5,95 ммоль/л (p&lt; 0,01); мочевины – 23,22 ммоль/л против 6,00 ммоль/л (p &lt; 0,01). Частота наступления летального исхода болезни была статистически значимо выше у пациентов с уровнем общего белка менее 52 г/л в 5,96 раз (ОР = 5,96, 95 % ДИ 1,32 – 26,89), глюкозы более 11 ммоль/л – в 7,00 раз (ОР = 7,00, 95 % ДИ 1,25 – 39,15), мочевины более 20 ммоль/л – в 7,05 раз (ОР = 7,05, 95 % ДИ 2,00 – 24,85).Заключение. Такие рутинные лабораторные показатели, как уровень общего белка, альбумина, глюкозы, натрия и мочевины, а также показатели свертывающей системы крови (МНО и АЧТВ) могут служить диагностическими и прогностическими критериями развития сепсиса и его исходов у пациентов с гнойно-воспалительными заболеваниями мягких тканей

IMMUNOHISTOCHEMICAL ANALYSIS OF CASPASE-3 ACTIVITY IN LIVER BIOPSIES OF PATIENTS WITH MONO AND MIXED INFECTIONS

Objective: to study the activity of proapoptotic signal protein caspase-3 for determination of peculiarities of apoptosis regulation under liver chronic diseases.Subjects and methods. The immunohistochemical analysis of caspase-3 activity in 5 liver biopsies of the patients with mono infection of chronic hepatitis B and 5 liver biopsies of the patients with mixed infection of tuberculosis, chronic hepatitis C and human immunodeficiency virus was fulfilled. Morphological and morphometric analysis of serial microphotographs was performed using an image analysis system (microscope Leica DM 2500, digital camera Leica DFC320 R2 and a computer).Results. The activity of caspase-3 as dark brown granularity was revealed in all tis-sue components of liver (hepatocytes, epithelium of bile ducts, endotheliocytes, Kupffer cells of sinusoids, in compositions of lymphohistiocyte infiltrations). The maximal activity was discovered in hepatocytes nuclei. The expression of caspase-3 was significantly higher in liver biopsies of the patients with mixed infection. It is typical that the immunoreactive hepatocytes had not any morphological marks of apoptosis.Conclusion. The caspase-3 expression of proapoptotic signal protein caspase-3 may serve as an early marker of liver damage including the possibilities of apoptosis development.</p
