输卵管梗阻性不孕症的常用治疗方法及研究进展

不孕症是妇科常见疾病,其发病率呈逐年上升的趋势,在我国其发病率约为7％～10％。在女性不孕症中,输卵管梗阻是最常见的原因之一,其中又以近端阻塞多见。目前,宫腹腔镜诊断输卵管通畅度已经成为诊断输卵管梗阻胜不孕症的金标准。但是,目前治疗输卵管梗阻性不孕症的方法及效果尚未统一,常用的治疗方法不能够对患者做出全面客观的评估及准确的治疗。宫腹腔镜手术联合导丝治疗输卵管梗阻性不孕症的方法是将内镜和介入技术联合使用,较好地解决了各种治疗方法的不足,该方法凭借其可视、微创、并发症少、输卵管再通率高等优点应用于,临床。本文将对女性输卵管梗阻性不孕症的常用治疗方法及研究进展做一综述。     

Transvaginal hydrolaparoscopy for diagnosis of tubal infertility

OBJECTIVE: Infertility problem affects more than 70 million couples worldwide, 5-15% of which are couples in their reproductive age. Less and less invasive endoscopic methods like transvaginal hydrolaparoscopy have been developed by technological progress. This method enables not only precise identification, but is now increasingly used for treatment of tubal and peritoneal factor pathology, which cause approximately 35 per cent of female infertility. AIM: Evaluation of transvaginal hydrolaparoscopy (HLTV) usefulness for diagnosis of tubal infertility comparing to standard laparoscopy and hysterosalpingography (HSG). Results: In evaluation of patent fallopian tubes results of HLTV and HSG examinations are coincide in 87%, while obstruction diagnosed in HSG is confirmed only in 37% during HLTV examination. Transvaginal hydrolaparoscopy and HSG have similar sensitivity and specificity in diagnosis of hydrosalpinx, which is up to 100% . In comparison with HLTV histerosalpingography is less effective in evaluation of peritubal dilatations and adhesions. Both laparoscopic surgery and transvaginal laparoscopy have the same high sensitivity in diagnostics of the fallopian tubes patency and hydrosalpinx, which is up to 100%. In evaluation of peritubal adhesions and dilatations the results are very similar. Conclusions: 1. HLTV is a highly useful method in evaluation of the fallopian tubes pathologies which is significantly more sensitive than HSG in evaluation of such lesions as peritubal adhesions and obstructed fallopian tubes. 2. HLTV is as effective as laparoscopy in evaluation of patency and lesions of the fallopian tubes. 3. HLTV is a less invasive method, much better tolerated than laparoscopy and more suitable for the group of overweight patients. 4. Final assessment of HTLV technique will be possible following performance of a greater number of studies, where the foregoing conclusions present only initial observations.     

Pancreatic endocrine tumors - management guidelines (recommended by the Polish Network of Neuroendocrine Tumors)

Pancreatic endocrine tumors (PETs) are rare neoplasms of this organ. The majority of PETs are tumors without hormonal activity. In this publication, we present the diagnostic and therapeutic guidelines for the management of these tumors proposed by the Polish Network of Neuroendocrine Tumors. These guidelines refer to biochemical and location diagnostics, including scintygraphy of somatostatin receptors, endoscopic ultrasonography and other anatomical and functional imaging methods. High importance is attached to correct histopathological diagnosis which determines further management of patients with PETs. Antitumor therapy requires multidirectional procedure, and therefore the rules of surgical treatment, biotherapy, chemotherapy and peptide receptor radionuclide therapy are discussed.     

Gastric bronchogenic cyst presenting as a submucosal mass: a case report

ABSTRACT: INTRODUCTION: Bronchogenic cysts are developmental anomalies of the primitive foregut which mostly occur in the lung. Gastric bronchogenic cysts are extremely rare; few cases have been reported in the literature and the diagnosis was often made following surgical resection. CASE PRESENTATION: A 40-year-old North African man was admitted to our hospital with a gastric submucosal mass. An endoscopic ultrasound revealed a unilocular cystic mass located in the muscular layer. Its content was echogenic suggestive of mucus. Magnetic resonance imaging confirmed the liquid nature of the cyst and showed a high ratio of proteins. Based on these observations, the diagnosis of bronchogenic cyst was confirmed. An endoscopic monitoring was decided rather than surgery because of the small size of the cyst and the absence of symptoms. CONCLUSION: Although gastric bronchogenic cysts are rare, they should be well known and considered in all differential diagnoses of gastric tumors. We report a new case of gastric bronchogenic cyst and highlight the contribution of morphological tests that currently allow a non-invasive diagnosis.

Neuroendocrine tumors of the small intestine and the appendix - management guidelines (recommended by The Polish Network of Neuroendocrine Tumors)

Polish recommendations regarding management of patients suffering from neuroendocrine tumors of small intestine and appendix are presented. Small intestine, especially ileum represent most common origin of these tumors. Majority of them are well differentiated and grow slowly. Rarely, they are less differentiated with fast growth and poor prognosis. Symptoms are atypical, diagnosis could be often accidental. In 4-10% of patients typical symptoms of carcinoid syndrome are present. Chromogranin A is useful in the laboratory diagnostics, and urinary excretion of 5-hydroxyindoloacetic acid is helpful for the diagnostics and monitoring of the disease. Histopathological diagnostics was extensively described. Ultrasound, colonoscopy, capsule endoscopy, baloon enteroscopy, computed tomography, magnetic resonance and somatostatin analogs scintigraphy could be used for the visualization. The treatment of choice in the neuroendocrine tumors of small intestine and appendix is radical or palliative surgery, if possible using endoscopy. Pharmacotherapy consists of biotherapy and chemotherapy. The crucial in biotherapy is somatostatin analogs application, possible in symptomatic treatment of hormonally functioning tumors. This is treatment of choice in carcinoid crisis. Interferon alfa could be applied because of the same indications as somatostatin analogs, except for carcinoid crisis. Chemotherapy is less successful in disseminated or locally advanced intestinal neuroendocrine tumors, so radioisotope therapy should be considered in each case of unresectable tumor.

Developmental engineering the kidney: Leveraging principles of morphogenesis for renal regeneration

Multiple methodological approaches are currently under active development for application in tissue engineering and regenerative medicine of tubular and solid organs. Most recently, developmental engineering (TE/RM), or the leveraging of embryonic and morphological paradigms to recapitulate aspects of organ development, has been proposed as a strategy for the sequential, iterative de novo assembly of tissues and organs as discrete developmental modules ex vivo, prior to implantation in vivo. In this article, we focus on the kidney to highlight in detail how principles of developmental biology are impacting approaches to TE of this complex solid organ. Ultimately, such methodologies may facilitate the establishment of clinically relevant therapeutic strategies for regeneration of renal structure and function, greatly impacting treatment regimens for chronic kidney disease.

Tumores hipofisarios no funcionantes: actualización 2012

Non-functioning pituitary adenomas are the most common pituitary macroadenomas in adults, accounting for approximately 14%-28% of all clinically relevant pituitary tumors. They are a heterogeneous group of tumors that cause symptoms by compression and/or hormone deficiencies. The possibility of tumor growth is increased in macroadenomas and solid tumors as compared to microadenomas and cystic tumors. Diagnosis is based on imaging procedures (magnetic resonance imaging), but there are studies reporting promising potential biomarkers. Transsphenoidal surgery remains the first therapeutic option for large tumors with compressive symptoms. There is no evidence that endoscopic procedures improve outcomes, but they decrease morbidity. There is no unanimity in finding prognostic predictors of recurrence. Radiosurgery achieves tumor control and, sometimes, adenoma size reduction. Its adverse effects increase with higher doses and tumor sizes > 4 cm³. Drug treatment is of little value. In aggressive non-functioning tumors, temozolomide (TMZ) may be used with caution because no controlled studies are available. TMZ achieves tumor control in 38%-40% of aggressive non-functioning tumors. The optimal treatment regimen and duration have not been defined yet. Lack of response to TMZ after 3 cycles predicts for treatment resistance, but initial response does not ensure optimal mid or long–term results. O6-methylguanine-DNA methyltransferase expression has a limited predictive value of response to treatment with TMZ in aggressive non-functioning tumors. It should therefore not be a determinant factor in selection of patients to be treated with TMZ.     

Interpretation of array comparative genome hybridization data: a major challenge

The advent and application of high-resolution array-based comparative genome hybridization (array CGH) has led to the detection of large numbers of copy number variants (CNVs) in patients with developmental delay and/or multiple congenital anomalies as well as in healthy individuals. The notion that CNVs are also abundantly present in the normal population challenges the interpretation of the clinical significance of detected CNVs in patients. In this review we will illustrate a general clinical workflow based on our own experience that can be used in routine diagnostics for the interpretation of CNVs.     

Aspiration cytology of ovarian neoplasms. A review

Unlike other gynecologic tumors, which are accessible to inspection and biopsy, ovarian neoplasms are located within the pelvis or abdomen and are reachable only by laparoscopy or exploratory laparotomy. Because of its simplicity, fine needle aspiration cytology may be used as an alternative to surgical procedures. However, because of the great variety of tumor types in the ovary, cytologic interpretation of aspirates from that organ represents one of the most challenging fields in diagnostic cytology. Nevertheless, as clinicians become more experienced in using this technique and pathologists gain confidence in their ability to evaluate samples correctly, aspiration cytology may prove to be one of the most valuable and acceptable tools in the diagnosis of tumors of the female pelvis.

Dental and minor physical anomalies in children with developmental disorders--a discriminant analysis

A discriminant analysis was performed in a sample of 303 children with developmental disorders (DD) and 303 healthy controls (C) in order to test whether some oro-dental and physical minor anomalies could discriminate these groups of children. DD sample comprised 176 mentally retarded (MR) children. 70 children with impaired hearing (IH) and 57 children with impaired vision (IV). The control group included 303 healthy subjects, matched for sex and age. The analysis comprised seven common oral and dental anomalies: median diastema, hypodontia, impacted teeth, microdontia, dens invaginatus, upper lip frenulum and frenulum of the tongue. Minor physical anomalies were assessed by the method proposed by Waldrop et al., as the average number of minor anomalies per individual (W1) and as the weighted score of minor anomalies (W2). Three discriminant functions were obtained by analysis of nine initial variables. Distinct discrimination and considerable distances were found between the centroids of the controls and all groups of DD children. The first two discriminant functions were significant for discrimination between the groups and they explained 98.6% of the total variance. The first function contained 90.2% of information and was defined by the number and weighted scores of minor anomalies. The second variable explained 8.4% of the total variability and was defined by three dental anomalies. The results obtained by the discriminant analysis show that application of dental and minor physical anomalies enables discrimination between the group of healthy children and the groups of children with different developmental disorders.     

腹腔镜胃癌根治术的研究进展

胃癌是全球发病率较高的恶性肿瘤之一,且发病率呈逐年上升的趋势。传统的治疗方法是开腹胃癌根治术,但该方法对患者机体造成的创伤较大,不利于患者术后恢复,在一定程度上影响了手术治疗的效果。随着医学技术的发展及"微创外科"理念的不断深入,腹腔镜手术以其创伤小、术中出血量少以及术后恢复快等特点被广泛应用于外科手术治疗中。近年来,3D腹腔镜技术的出现使手术视野更加清晰,术中操作更加简便,在一定程度上提高了手术的安全性,但临床对于进展期胃癌根治术的远期疗效一直存在争议。因此,本文对腹腔镜在胃癌根治术中的作用及意义作以综述,为胃癌的微创治疗提供理论参考。     

Increasing age influences uterine integrity, but not ovarian function or oocyte quality, in the cheetah (Acinonyx jubatus)

Although the cheetah (Acinonyx jubatus) routinely lives for more than 12 yr in ex situ collections, females older than 8 yr reproduce infrequently. We tested the hypothesis that reproduction is compromised in older female cheetahs due to a combination of disrupted gonadal, oocyte, and uterine function/integrity. Specifically, we assessed 1) ovarian response to gonadotropins; 2) oocyte meiotic, fertilization, and developmental competence; and 3) uterine morphology in three age classes of cheetahs (young, 2-5 yr, n = 17; prime, 6-8 yr, n = 8; older, 9-15 yr, n = 9). Ovarian activity was stimulated with a combination of equine chorionic gonadotropin and human chorionic gonadotropin (hCG), and fecal samples were collected for 45 days before gonadotropin treatment and for 30 days after oocyte recovery by laparoscopy. Twenty-six to thirty hours post-hCG, uterine morphology was examined by ultrasound, ovarian follicular size determined by laparoscopy, and aspirated oocytes assessed for nuclear status or inseminated in vitro. Although no influence of age on fecal hormone concentrations or gross uterine morphology was found (P > 0.05), older females produced fewer (P < 0.05) total antral follicles and oocytes compared to younger counterparts. Regardless of donor age, oocytes had equivalent (P > 0.05) nuclear status and ability to reach metaphase II and fertilize in vitro. A histological assessment of voucher specimens revealed an age-related influence on uterine tissue integrity, with more than 87% and more than 56% of older females experiencing endometrial hyperplasia and severe pathologies, respectively. Our collective findings reveal that lower reproductive success in older cheetahs appears to be minimally influenced by ovarian and gamete aging and subsequent dysfunction. Rather, ovaries from older females are responsive to gonadotropins, produce normative estradiol/progestogen concentrations, and develop follicles containing oocytes with the capacity to mature and be fertilized. A more likely cause of reduced fertility may be the high prevalence of uterine endometrial hyperplasia and related pathologies. The discovery that a significant proportion of oocytes from older females have developmental capacity in vitro suggests that in vitro fertilization and embryo transfer may be useful for "rescuing" the genome of older, nonreproductive cheetahs.
