X-ray diagnosis of disturbed bronchial permeability in chronic bronchitis

The authors presented clinical and x-ray findings of combined investigation of 94 patients with chronic bronchitis. X-ray symptoms of disturbed bronchial permeability (DBP) in this pathology were studied. Bronchograms, bronchosonograms performed in different phases of respiration using broncholytic drugs, video tape recording, coherent-optic processing of bronchograms, and a method of digital processing of bronchograms proposed by the authors were employed. The importance of x-ray examination in the diagnosis of DBP was shown. The classification, nature, site and spreading of DBP were described. X-ray findings were compared with clinical and laboratory findings.     

Computed tomography in the comprehensive diagnosis of acute diseases and injuries

The author presents the results of a CT use during combined investigation on 2500 patients and the wounded who were admitted to hospital on emergency as well as patients who developed serious complications during treatment, especially in the postoperative period. CT findings were verified during operation, at autopsy or during a follow-up. They were indicative of a high effectiveness of emergency CT of different organs and systems in the diagnosis of lesions, acute diseases and their complications. The use of CT permitted considerable reduction of a diagnostic (preoperative) period, a decrease in use of routine invasive x-ray and surgical methods, and the improvement of therapeutic results.     

A complex x-ray study of patients with enterocutaneous fistulas

The paper is concerned with analysis of the results of x-ray examination of 78 patients with enterocutaneous fistulas of various etiology and site. The authors have shown the characteristic features of x-ray examination of patients in whom the fistulas were at the acute phase of their development. They have also defined the diagnostic value of the employed methods and their efficacy for the diagnosis not only of fistulas but also of related complications (inflammatory infiltrates and abscesses of the abdominal cavity, fatty phlegmon, purulent "fillings", complicated fistulas, etc.). During combined x-ray investigation accurate diagnosis of fistulas was established in 97.4% of the patients, purulent complications were revealed in 94.6%.     

X-ray diagnosis of a phlegmon of the retroperitoneal space tissue]

The paper is concerned with the results of a combined x-ray study of 36 patients with phlegmon of retroperitoneal fat (RF). The x-ray procedure was described, potentialities and effectiveness of each method (panoramic polypositional investigation of the chest and peritoneal cavity, a contrast study of the G.I. tract) were shown. X-ray semeiotics of phlegmon of RF of different sites, the main differential and diagnostic signs to distinguish between phlegmon and accumulation of gases of other sites and its causes, were described in detail. The accuracy of phlegmon detection with these methods was 97.2%; phlegmon was detected in 35 of 36 patients.

经阴道超声联合血清AFP、PAI-1及MMIF对子宫内膜异位症的诊断价值分析

摘要 目的：探讨经阴道超声联合血清甲胎蛋白（AFP）、纤溶酶原激活物抑制物1（PAI-1）及巨噬细胞移动抑制因子（MMIF）对子宫内膜异位症的诊断价值。方法：选取我院2021年8月到2023年8月收治的150例子宫内膜异位症患者进行回顾性分析,分析其经阴道超声检查图像特征,并以病理诊断作为"金标准",分析阴道超声对宫内膜异位症的阳性检出率。依照子宫内膜异位症分期,将其分为Ⅰ~Ⅱ期组（n=77）,Ⅲ~Ⅳ期组（n=73）,另选取同期来我院体检的150例健康女性作为对照组。分析三组受检者血清AFP、PAI-1及MMIF表达水平,并采用Spearman相关分析法分析AFP、PAI-1及MMIF与子宫内膜异位症的相关性。最后建立受试者特征（ROC）工作曲线分析经阴道超声联合血清AFP、PAI-1及MMIF对子宫内膜异位症的诊断效能。结果：150例子宫内膜异位症患者均经病理诊断确诊,通过经阴道超声检查确诊为子宫内膜异位症的患者128例,85.33%。其中75例患者为卵巢型,超声显示巨大巧克力囊肿,内部可见大量细密点状回声与分隔光带。53例患者为子宫型,超声显示后壁腺肌瘤,内部回声不均匀,可见片状无回声区域;三组受检者血清AFP、PAI-1及MMIF表达水平对比差异显著,Ⅲ~Ⅳ期组明显高于Ⅰ~Ⅱ期组和对照组,差异具有统计学意义（P＜0.05）;Spearman相关分析结果显示：AFP、PAI-1及MMIF与子宫内膜异位症呈正相关（P＜0.05）;诊断灵敏度和特异度从低到高依次为MMIF（52.58%、64.32%）、PAI-1（60.03%、67.53%）、AFP（65.24%、71.27%）、经阴道超声（73.25%、86.36%）、经阴道超声联合血清AFP、PAI-1及MMIF（84.26%、98.63%）。经阴道超声联合血清AFP、PAI-1及MMIF的诊断灵敏度明显高于单一指标诊断（P＜0.05）。结论：经阴道超声联合血清AFP、PAI-1及MMIF对子宫内膜异位症的诊断价值较高,其灵敏度和特异度分别为84.26%、98.63%,通过联合诊断可进一步辅助减少子宫内膜异位症的误诊和漏诊几率,为子宫内膜异位症的诊断与治疗提供重要参考。     

Clinico-roentgenologic diagnosis of disseminated and diffuse lung diseases

The results of clinical and x-ray investigations of 398 patients with disseminated pulmonary lesions were analyzed. Two groups were identified: patients with interstitial type of lesions (101) and patients with focal type of lesions (297). Proceeding from roentgeno-morphological correlations, the authors presented specified roentgeno-semiotics of 10 nosological entities with the syndrome of pulmonary dissemination. The possibilities of optimization of differential diagnosis of disseminated pulmonary lesions were shown basing on combined (clinical, functional and roentgenological) investigation.     

Ultrasonic echography in the diagnosis of urolithiasis]

The paper is concerned with comparison of the results of ultrasound and x-ray investigation in 110 patients with urolithiasis. A possibility was established to diagnose roentgenonegative concrements in the kidneys and pelvicalyceal system with the help of ultrasound echography. The results of x-ray investigation were more reliable for the localization of uretero- and cystoliths. Ultrasound echography in such patients permitted the detection of complications (hydrocalycosis and hydronephrosis) as well as the assessment of the time course of complications in the postoperative period.     

X-ray diagnosis of echinococcosis of the bones

The paper is devoted to the authors' experience in echinococcosis of the bones in 18 patients. The most important method for the recognition of this disease is x-ray investigation.     

X-ray studies in the diagnosis of pyloroduodenal ulcerative stenoses

Combined clinical and x-ray investigation of 100 patients operated on for pyloroduodenal ulcerative stenoses was conducted. Methods of polypositional and polyprojectional x-ray investigation including a double contrast study and a differentiated use of cholinolytic and cholinomimetic drugs were standardized. The x-ray classification of stenosis was improved on the basis of radiological and surgical correlations and quantitative analysis of indices characterizing a degree of stenosis compensation. Criteria for the determination of a degree of stenosis were worked out.     

A Low-Testosterone State Associated with Endometrioma Leads to the Apoptosis of Granulosa Cells

Although endometriosis is suspected to be a cause of premature ovarian insufficiency (POI), the mechanism(s) underlying this process have not been elucidated. Recently, androgens were shown to promote oocyte maturation and to play a role in folliculogenesis. In addition, several reports have documented low testosterone levels in the follicular fluid obtained from endometriosis patients. We therefore examined whether the low levels of serum testosterone are associated with the apoptosis of granulosa cells in follicles obtained from endometriosis patients. Serum samples were collected from 46 patients with endometriosis and from 62 patients without endometriosis who received assisted reproductive therapy. Specimens of the ovaries obtained from 10 patients with endometrioma were collected using laparoscopy. The mean serum testosterone concentration in the patients with endometriosis was significantly lower than that observed in the patients without endometriosis. Furthermore, high expression of a pro-apoptotic Bcl-2 member, BimEL, in the follicles was found to be associated with a low serum testosterone level. We clarified the underlying mechanisms using a basic approach employing human immortalized granulosa cells derived from a primary human granulosa cell tumor, the COV434 cell line. The in vitro examination demonstrated that testosterone inhibited apoptosis induced by sex steroids depletion via the PI3K/Akt-FoxO3a pathway in the COV434 cells. In conclusion, we elucidated the mechanism underlying the anti-apoptotic effects of testosterone on granulosa cells, and found that a low-testosterone status is a potentially important step in the development of premature ovarian insufficiency in patients with endometriosis.     

Computed tomography in the x-ray diagnosis of pneumonia

Experience in the use of CT in combined radiodiagnosis of pneumonia was analysed. It has been concluded that CT objectively reflects morphological inflammatory pulmonary changes and permits their all-round assessment over time. The diagnosis of pneumonia in CT is based on classical x-ray symptoms. As compared to survey radiography CT reveals symptoms of pneumonia to the full at earlier stages. CT is an important additional method of investigation of inflammatory pulmonary diseases, but it should not be used separately without survey radiography. In a majority of cases when CT is performed there is no need in x-ray tomography.     

Potentialities of lymphography using chromethiotrast, a new x-ray contrast medium]

A study was made of the potentialities of lymphography using a new radiopaque medium chromethiotrast (a solution of harmless fat-soluble anthraquinone dyes fixed with ethiotrast). The agent is intended for combined x-ray and visual investigation of the lymphatic system. Lymphograms of 76 patients (with Hodgkin's disease, prostatic cancer, cancer of the female organs, breast, bladder, rectal cancer, and secondary limb lymphedema) were analyzed. Chromethiotrast is easily administered in the lymphatic bed ensuring a good contrast density of the lymphatic vessels permitting the detection of their structure. Chromethiotrast is quickly discharged from the lymphatic system, causing no marked side-effects provided all precautions necessary for the administration of iodobutyric radiopaque media, are taken.     

Hyperprolactinemia and luteal insufficiency in infertile patients with mild and minimal endometriosis.

The objective of the present paper was to assess the presence of hormonal alterations in infertile women with stage I or II endometriosis (Group III, n = 20) compared to fertile women without endometriosis (Group I, n = 14) and to fertile women with endometriosis (Group II, n = 7). Serum levels of FSH, LH, estradiol, TSH, and PRL were measured between days 1 and 5 of the early follicular phase; in the luteal phase, three serum samples were collected for progesterone measurement, and endometrial biopsies were performed. Serum estradiol levels were lower (p = 0.035) in infertile patients with endometriosis than in fertile patients without endometriosis. Six infertile patients with endometriosis presented prolactin levels above 20 ng/ml. This was not observed in the other groups. Luteal insufficiency was more frequent in infertile patients with endometriosis (78.9%) than in fertile patients with (42.9%) or without endometriosis (0%). In a multiple logistic regression analysis, only the presence of endometriosis and infertility was significantly associated with luteal insufficiency. The serum levels of LH, FSH, and TSH were not significantly different among the groups. Luteal insufficiency and altered prolactin secretion were associated with endometriosis, and could be important mechanisms causing infertility in this group of patients.     

X-ray characteristics of acute intestinal obstruction in middle-aged and elderly patients

The authors presented clinical and x-ray findings of 188 patients with mechanical intestinal obstruction (92 of them were middle-aged and advanced in years and 96 were under 60). A combined program of x-ray examination included 3 stages: panoramic polypositional roentgenography of the chest and abdominal cavity, dynamic x-ray control over the state of the abdominal cavity, and contrast study of the G.I. tract. A distinctive feature of the x-ray symptomatology of intestinal obstruction in middle-aged and old patients was the absence of classical x-ray symptoms in some cases during panoramic roentgenography of the abdominal cavity. In patients over 60, x-ray symptomatology was characterized by marked colon distension and intestinal distension of various degree in 77.1%     

Radiodiagnosis of traumatic injuries of the kidneys in children

Altogether 35 children (21 boys and 14 girls) with traumatic renal lesions ages 5 to 14 were examined, of them 23 were subjected to operation 2-13 h after injury, 12 patients received conservative therapy. The patients were divided into 3 groups with relation to a degree of severity of injury: mild (12 patients), moderate (20 patients) and grave (3 patients). All the children were given combined clinical, x-ray and radiological examination. Normally the most informative diagnostic method was excretory urography, particularly its infusion variant. Renography, renoscanning or dynamic renoscintigraphy were employed for observation over time to reduce radiation exposure.     

Low Birth Weight Is Strongly Associated with the Risk of Deep Infiltrating Endometriosis: Results of a 743 Case-Control Study

The influence of intrauterine environment on the risk of endometriosis is still controversial. Whether birth weight modifies the risk of endometriosis in adulthood remains an open question. For this purpose, we designed a case-control study involving 743 women operated on for benign gynecological indications from January 2004 to December 2011. Study group included 368 patients with histologically proven endometriosis: 54 superficial endometriosis (SUP), 79 endometriomas (OMA) and 235 deep infiltrating endometriosis (DIE). Control group included 375 patients without endometriosis as surgically checked. Mean birth weights were compared between patients and controls, according to endometriosis groups and rAFS stages. Mean birth weight was significantly lower for patients with endometriosis as compared to controls (3,119g ± 614 and 3,251g ± 557 respectively; p = 0.002). When compared to controls, patients with DIE had the lowest birth weight with a highly significant difference (3,103g ± 620, p = 0.002). In univariate analysis, patients with low birth weight (LBW), defined as a BW < 2,500g, had a higher risk of endometriosis, especially DIE, as compared to the reference group (OR = 1.5, 95%CI: 1.0-2.3 and OR = 1.7, 95%CI: 1.0-2.7, respectively). Multivariate analysis, adjusted on ethnicity and smoking status, showed the persistence of a significant association between endometriosis and LBW with a slight increase in the magnitude of the association (aOR = 1.7, 95%CI: 1.0-2.6 for endometriosis, aOR = 1.8; 95%CI: 1.1-2.9 for DIE). In conclusion, LBW is independently associated with the risk of endometriosis in our population. Among patients with LBW, the risk is almost two-times higher to develop DIE. This association could reflect common signaling pathways between endometriosis and fetal growth regulation. There is also the possibility of a role played by placental insufficiency on the development of the neonate’s pelvis and the occurrence of neonatal uterine bleeding that could have consequences on the risk of severe endometriosis.
