Peritonitis caused by a giant trichobezoar ventriculi--a case report

Bezoars are the most common foreign bodies of gastrointestinal tract. They contain swallowed hair, different fibres, seeds, nut shells, sweets or drugs. Clinical manifestations vary, depending on the location and size of bezoar, from "no symptoms" to "acute abdomen" syndrome. In this case report, the authors describe a giant trichobezoar from the stomach of an 18-year-old girl, who had been admitted to the gynecological department with syndromes suggesting an ovarian cyst torsion. The preoperative diagnosis was not confirmed and a giant trichobezoar was found and removed during the surgery.     

Differential flow cytometric detection of intracellular cytokines in peripheral and peritoneal mononuclear cells of women with endometriosis

OBJECTIVE: The pathogenesis of endometriosis is related to functional changes in CD3+ and CD14+ cells observed both at the local and systemic level. Here we investigated whether, and if so, how the body compartment influences cytokine expression in stimulated peritoneal and peripheral CD3+ and CD14+ cells of women with endometriosis. STUDY DESIGN: Isolated peripheral blood (PB) and peritoneal fluid (PF) mononuclear cells from women with endometriosis were cultured under non-adherent conditions and stimulated with PMA and ionomycin for 6h to induce intracellular cytokine synthesis of TNF-alpha, IFN-gamma, and IL-8 by CD3+ cells or with LPS for 9h to produce TNF-alpha, IL-6, IL-10, MCP-1, and IL-8 by CD14+ cells. RESULTS: The percentages of positive CD3+ cells stained for TNF-alpha and IFN-gamma were significantly higher and those stained for IL-8 were significantly lower in PF compared with PB, this being independent of the stage of endometriosis. In contrast, the percentages of CD14+ cells producing TNF-alpha, IL-6, IL-10, MCP-1, and IL-8 were significantly higher in PB than PF of women with endometriosis. CONCLUSIONS: Monocytes/macrophages and lymphocytes derived from the peripheral and peritoneal compartments of women with endometriosis differentially respond to stimulated cytokine synthesis induction. However, it is difficult to state whether the observed phenomenon is more related to body compartment influence per se or to the presence of endometriosis.     

The importance of chlamydial infections in obstetrics and gynaecology: an update

Chlamydia is now the most common notifiable infectious disease in many countries, a fact that has serious ramifications for the reproductive health of women. This review highlights the epidemiology, pathophysiology, clinical features and reproductive sequelae of the infection. Current screening and management methods are outlined. Obstetricians and gynaecologists are ideally placed to play a major role in the primary prevention of this significant sexually transmitted infection.     

The role and place of the assisted reproductive technology (ART) in treatment of infertility

The assisted reproductive technics (ART) compose the very valuable tool in the infertility treatment additionally to pharmacological and surgical methods. ART comparises the classical in vitro fertilization and embryotransfer (IVF/ET) intracytoplasmic sperm injection (ICSI) intrauterine insemination (IUI), microepididymal sperm spiration (MESA), and testicular sperm aspiration (TESA). Male infertility, tubal factor, ovarian factor, endometriosis or an unexplained infertility constitute pathologies where ART can be applied as the methods of choice or as the methods of the last chance. The efficacy of ART is closely related to the age of the female partner. Hence, taking a decision of the inappropriate treatment of the infertility and prolongation of such treatment for years is the "Theft" of the reproductive time of women and a diminution or even deprivation of the chance for pregnancy. The role and the appropriate time of the ART application in different infertility causes are described.     

FURTHER STUDIES ON THE ETIOLOGICAL R?LE OF VIBRIO FETUS

The data bearing on these three cases are quite sufficient to rule out Bacillus abortus as the agent. Not only the cultures and guinea pig tests of fetal tissues and contents of the digestive tract, but also the agglutination and guinea pig tests of the milk, were negative. The same is true of the agglutination tests of the blood serum. Only in one case was the placenta obtained in part. The stained films and the sections from various regions showed no abortion bacilli. Guinea pig tests of placental tissue were negative for Bacillus abortus. On the other hand) minute organisms resembling vibrios were detected in the cytoplasm of endothelial cells within capillaries in the edematous subchorionic tissue. Subsequently the agglutination titer of the blood serum of one of these cases rose to a level indicating infection with Bacillus abortus during the second pregnancy. The peculiar distribution of abortions due to Vibrio fetus among older cows and heifers in this herd, resulting at first in cases among older cows and latterly passing to young stock, may be explained by certain occurrences in the herd itself. It may be assumed that the infection was originally brought in by purchased cows. The young stock is kept segregated from these in a special barn, and when 6 months old it is pastured on outlying farms until returned in an advanced stage of pregnancy. The heifers during the first pregnancy were thus kept away from vibrio carriers until after the first calf was born. In June and July, 1919, 55 older cows, purchased and native, were placed on the young stock pasture. The three cases of abortion in heifers due to Vibrio fetus occurred October 24, November 9, and December 2, 1919. The age and condition of the fetuses accord very well with the assumption that Vibrio fetus was introduced among the young stock in June or July of the same year. The information gathered thus far concerning vibrionic abortion in this herd enables us to formulate a tentative hypothesis subject to modification with increasing knowledge of this type of infectious abortion. The infectious agent was probably introduced by purchased cows in 1917 or earlier. It gained a certain headway up to 1919, then the number of cases declined so that between May, 1919, and May, 1920, only the above three cases in heifers, and one case of mixed infection with Bacillus abortus in an older cow, were detected. During the same period cases due to Bacillus abortus continued undiminished. The greater resistance of Bacillus abortus manifested in cultures as compared with Vibrio fetus is thus reflected in its behavior in nature. The temporary dying out of the infection indicates that natural immunization of a herd to Vibrio fetus proceeds quite rapidly. Another outbreak may be expected when the immunity of the herd has declined in the absence of the infecting agent and the latter is reintroduced from without, or it may reappear at any time when a vibrio of higher virulence is brought in.     

High Prevalence of Physical Frailty Among Community-Dwelling Malnourished Older Adults–A Systematic Review and Meta-Analysis

Background

Malnutrition and frailty are two geriatric syndromes that significantly affect independent living and health in community-dwelling older adults. Although the pathophysiology of malnutrition and physical frailty share common pathways, it is unknown to what extent these syndromes overlap and how they relate to each other.

Evaluation of the genotoxic potential of dimethyl sulfoxide (DMSO) in meristematic cells of the root of Vicia faba

Dimethyl sulfoxide (DMSO) is an organic solvent with several biological applications. It is extensively used to dissolve compounds that hardly dissolve in water to detect their genotoxic activity in vitro. In this study DMSO will be tested to determine its genotoxic potential. The effect of DMSO on the frequency of chromosomal aberrations in anaphase as well as DNA fragmentation through the comet assay has been evaluated in the meristematic cells of the root tips of Vicia faba. It has been observed that the frequency of chromosomal aberrations increases when the concentration of DMSO increases, reaching its maximum value with 20% of DMSO and decreasing at 30 and 40% of DMSO, in comparison to this maximum value, but significantly higher than the values observed in the control. Similarly, the percentage of fragmentation and damage index evaluated through the comet assay showed the same behavior; some of the possible mechanisms of action are discussed.
