Synthetic cyanoacrylic glue in the prevention of post-operative lymphocele after pelvic lymphadenectomy in patients with uterine malignancies: A prospective, single-blind, preliminary study.

OBJECTIVES: Lymphoceles are among the most common post-operative complications of pelvic lymphadenectomy, with a reported incidence of 1% to 29% in gynecology oncology. Several studies evaluated the effectiveness of biological glues on reducing lymphoceles, but no data on gynecological patients are available. We evaluated the effectiveness of cyanoacrylic glues (n-butyl cyanoacrylate) (Glubran 2 - GEM s.r.l., Italy) in preventing lymphocele on 30 patients who underwent pelvic lymphadenectomy for endometrial or cervical cancer. METHODS: Single-blind prospective randomized study. Patients were divided into 2 groups: pelvic lymphadenectomy plus n-butyl cyanoacrylate (treatment group: 44 patients) and pelvic lymphadenectomy without n-butyl cyanoacrylate (control group: 44 patients). Primary endpoint was incidence of pelvic lymphocele in the two groups 30 days after surgery, and evaluated with pelvic ultrasound and RMI examination. Secondary endpoints evaluated drainage volume of lymphorrhea 36, 48, 72 and 96 h after surgery. RESULTS: 15% in the treatment group and 36.6% in the control group had lymphocele 1month after the procedure (p<0.03; RR 0.4 [95% CI 0.152-0.999]). Concerning the secondary outcome in group A the amount of lymphorrhea presented a constant significant decrease during evaluation; on the contrary, in group B, after an initial decrease at 48 h, the amount of lymphorrhea remained unchanged; at all considered times the amount of lymphorrhea resulted significantly greater in controls. CONCLUSION: Intraoperative application of n-butyl cyanoacrylate seems to reduce lymph production after pelvic lymphadenectomy, providing a useful additional treatment option for reducing drainage volume and preventing lymphocele development after pelvic lymphadenectomy.

A case of extraovarian primary peritoneal carcinoma in an oophorectomized-hysterectomized patient: a diagnostic dilemma.

Extra Ovarian Primary Peritoneal Carcinoma (EOPPC) is a rare type of adenocarcinoma of the pelvic and abdominal peritoneum. The objective examination and the histological aspect of the neoplasia virtually overlaps with that of ovarian carcinoma. The reported case is that of a 72 year-old patient who had undergone a total hysterectomy with bilateral annessiectomy surgery 20 years earlier subsequently to a diagnosis for uterine leiomyomatosis. The patient came to our attention presenting recurring abdominal pain, constipation, weight loss, severe asthenia and fever. Her blood test results showed hypochromic microcytic anemia and a remarkable increase CA125 marker levels. Instrumental diagnostics with Ultrasound (US) and CT scans indicated the presence of a single peritoneal mass (10-12 cm diameter) close to the great epiploon. The patient was operated through a midline abdominal incision and the mass was removed with the great omentum. No primary tumor was found anywhere else in the abdomen and in the pelvis. The operation lasted approximately 50 minutes. The post-operative course was normal and the patient was discharged four days later. The histological exam of the neoplasia, supported by immunohistochemical analysis, showed a significant positivity for CA 125, vimentin and cytocheratin, presence of psammoma bodies, and cytoarchitectural pattern resembling that of a serous ovarian carcinoma even in absence of primitiveness, leading to a final diagnosis of EOPPC. The patient later underwent six cycles of chemotherapy with paclitaxel (135 mg/m²/24 hr) in association with cisplatin (75mg/m²). At the fourth year follow-up no sign of relapse was observed.

Quality of life, lifestyle behavior and employment experience: a comparison between young and midlife survivors of gynecology early stage cancers.

GOALS: To evaluate differences and changes in quality of life (QoL), lifestyle behavior and employment experience of young in comparison to midlife adults in response to early stage gynecologic cancer diagnoses. METHODS: 263 patients, divided into two age groups (Group A: ≤ 45 and Group B: >45 years), were interviewed on their QoL, lifestyle behavior (dietary habits, tobacco and alcohol use, physical activity) and employment experience (employment status and working time) at diagnosis and within 4 years from the treatment. The QoL was evaluated by European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 (QLQ-C30) and its specific modules for each cancer type (in particular endometrium, cervix, ovarian and breast). RESULTS: Global health status was significantly different between the two groups. In the younger age group a more relevant cancer interference on family life and social activities and a greater impact on perception of health status have been observed. Young women were more affected by fatigue, constipation, gastrointestinal symptoms, lymphedema, poor body image and impaired sexuality. Cancer diagnosis had a major negative impact on employment of younger patients. Conversely, younger patients had overall better health behavior. They reported a higher daily intake of fruits and vegetables, along with lower alcohol consumption, furthermore they were a little more physically active than midlife adults. CONCLUSIONS: To enhance quality of life and to promote healthy lifestyle behavior of female cancer patients, particularly in younger age, it is essential to assure multidisciplinary approaches with specific medical intervention and psychosocial supports. Indeed, midlife adults seem to have a more rapid adaptive tendency to return towards levels of well-being, following cancer diagnosis and treatment, than younger patients.

Primary squamous cell carcinoma of the endometrium: a case report.

BACKGROUND: Primary endometrial squamous cell carcinoma (PSECC) is a rare neoplasm. Squamous epithelium derived from endometrioid cancer or from cervical squamous cell carcinoma. The prevalence is about 0.1%. The genesis, histogenesis and biological behavior are unknown. CASE PRESENTATION: A 48-year old woman in postmenopause, referring pelvic pain and vaginal bleeding. Transvaginal ultrasound showed a bulky uterus with the endometrium containing an hyperecogenic area. Endometrial biopsy found an epidermoid carcinoma. MRI showed a 4 x 2 x 1.2 cm mass occupying the uterine cavity. The patient underwent radical treatment. Pathological examination showed features of PSECC. The mutation of p53 tumor suppressor protein was disclosed in 15% of neoplastic cells. PCR revealed the absence of HPV DNA. CONCLUSIONS: The findings of our case move us to underline that the pathogenesis of this tumor is still unclear. Moreover, preoperative diagnosis and staging of PESCC is extremely difficult. Most patients do not show characteristic symptoms and predisposing factors, making it almost impossible to diagnose the precise localization of tumor origin.

Management of Cesarean Scar Pregnancy: A Single-Institution Retrospective Review.

OBJECTIVE: Cesarean scar pregnancy (CSP) is a rare condition that occurs when the pregnancy implants in a cesarean scar. An early diagnosis and a proper management are fundamental to prevent maternal complications. We review and discuss the different treatment employed in our unit to reduce morbidity, preserve fertility, and predict possible complications. METHODS: The reported treatment has been expectant management, operative hysteroscopy approach, and intramuscular injection of 50 mg methotrexate (MTX), followed by cervical dilation and manual vacuum aspiration (D&S) with a Karman cannula under ultrasound guidance, uterine artery embolization (UAE), and manual vacuum aspiration under ultrasound guidance and uterine artery embolization before surgical laparotomic resection. RESULTS: Complications were more frequent in women with a history of three or more cesarean section deliveries and with a myometrial thickness thinner than 2 mm. MTX and D&S treatment appear to be most effective and safe at the early age of pregnancy, while UAE and D&S are related to the highest risk of complication in any age of pregnancy. CONCLUSION: An appropriate preoperative diagnostic evaluation, the identification of cases at higher risk, and those eligible for a conservative treatment are fundamental to reduce complications.

CAR-3, a monoclonal antibody-defined antigen expressed on human carcinomas.

Several monoclonal antibodies were raised against the human epidermoid carcinoma line A 431. The antibody produced by clone AR-3, when tested in enzyme-linked immunosorbent assay, was found to react with the cell line used as immunogen, the human gastric carcinoma line KATO III, the colon carcinoma line HT29, and the ovarian carcinoma line SW626. This monoclonal antibody was found unreactive when tested on human peripheral blood leukocytes or on a number of normal or neoplastic cell lines. The antibody precipitated a high-molecular-weight glycosylated component. When tested on paraffin sections by the avidin:biotin: peroxidase method, the AR-3 antibody stained pancreatic (6:7), gastric (11:14), ovarian (5:6), colon (4:8), endometrial (4:6), and cervical (4:7) carcinomas. A small minority of carcinomas of other organs was also stained. Sarcomas, lymphomas, and other tumors of nonepithelial origin were constantly negative. Staining of some normal epithelial cells was also observed. Among the fetal tissue tested, the antibody reacted with pancreatic ducts and the small intestine. The antibody recognized metastatic carcinoma cells in peritoneal effusions. On the basis of its tissue distribution, the antigenic determinant defined by the AR-3 monoclonal antibody was called CAR-3. The monoclonal AR-3 did not cross-react with partially purified preparations of carcinoembryonic antigen, gastrointestinal carcinoma antigen, or the human milk fat globule antigen. The AR-3 MAb appear, thus, to broaden the number of available reagents for histopathological diagnosis of carcinomas.

Treatment of simple renal cysts by percutaneous drainage with three repeated alcohol injection.

OBJECTIVES: This study sought to show the effectiveness and safety of three repeated alcohol injections for the treatment of simple large renal cysts. METHODS: From September 1991 to December 1997 we treated 72 renal cysts. The cyst was drained with an 8F mono J stent. Ninety-five percent sterile ethanol was injected into the cyst and left in place for 20 minutes. Two repeat alcohol injections were performed every 24 hours. After the third alcohol injection, the catheter was removed. To avoid pain in the last 39 patients, 20 mL of 2% lidocaine hydrochloride was injected into the cyst for 15 minutes before the alcohol injections. RESULTS: The follow-up period ranged from 8 to 83 months (mean 48). One patient underwent surgical intervention because of considerable bleeding in the cystic cavity that occurred after percutaneous drainage. In 1 patient in whom the cystic cavity communicated with the urinary tract, no alcohol injections were performed. After the repeated alcohol injections, the cystic cavity completely disappeared in 68 of the 70 treated cysts at first ultrasound examination. This result, observed at the first ultrasound control observation, remained unchanged during follow-up. CONCLUSIONS: In our experience, percutaneous drainage with three repeated alcohol injections offers a high rate of success without the cost and morbidity associated with other procedures, such as operation or laparoscopy.

Laparoscopic vs open hepatic resection: a comparative study.

BACKGROUND: Although the feasibility of minor laparoscopic liver resections (LLR) has been demonstrated, data comparing the open vs the laparoscopic approach to liver resection are lacking. METHODS: We compared 30 LLR with 30 open liver resections (OLR) in a pair-matched analysis. The indications for resection were malignant disease in 47% of the LLR and 83% of the OLR. The average size of the lesions was 42 mm for LLR and 41 mm for OLR. Five wedge resections, 12 segmentectomies, and 13 bisegmentectomies were performed in each group. RESULTS: The conversion rate for LLR was nil. The mean operative time was 148 min for LLR and 142 min for OLR. Mean blood loss was minimal in the LLR group (320 vs 479 ml; p < 0.05). Postoperative complications occurred in 6.6% of the patients in each group; there were no deaths. The mean postoperative hospital stay was shorter for LLR patients (6.4 vs 8.7 days; p < 0.05). In tumors, the resection margin was <1 cm in 43% of the LLR patients and 40% of the OLR patients ( p = NS). CONCLUSIONS: Minor LLR of the anterior segments has the same rates of mortality and morbidity as OLR. However, the laparoscopic approach reduces blood loss and postoperative hospital stay.

[Treatment of voluminous renal cysts with drainage and repeated percutaneous administration of alcohol. Our experience]. / Trattamento di cisti renali voluminose mediante svuotamento ed alcoolizzazione percutanea ripetuta. Nostra esperienza.

The Authors report their experience on the treatment of simple voluminous renal cysts with an echo-guided puncture followed by a sclerosis, that is repeated thrice, with an endocavitary injection of pure alcohol. Since the fair results (94% of success) that were obtained after a mean follow-up of 16 months, the low invasivity of the method and the benignity of the disease, should propose the method itself as the first approach for the treatment of voluminous but not complicated renal cysts.

[Usefulness of transvaginal echography in the study of organic pathology of the female urethra]. / Utilità dell'ecografia trans-vaginale nello studio della patologia organica dell'uretra femminile.

The Authors describe their experience about the use of vaginal ultrasound in the diagnosis of some organic disease of the female urethra. The ultrasonography was performed with the 5 Mhz endocavitary probe and patients in lithotomy position and filled bladder. With this method has been possible value the urethral and peri-urethral echostructure and urethral calibre during micturition. the Authors visualized 20 urethral diverticula, 6 stenosis, 2 carcinomas and 1 leiomyoma. They show the great reliability of this investigation and argue that it may be present as a first instrumental approach in the clinical suspicion of an organic pathology of the female urethra.

[Treatment of a solitary renal cyst using percutaneous drainage and repeat alcoholization]. / Trattamento delle cisti renali semplici mediante drenaggio percutaneo con alcolizzazione ripetuta.

The Authors report their results on the treatment of simple voluminous renal cyst with percutaneous drainage and three times repeated sclerosis with pure alcohol every 24 hours. After a mean follow-up of 28 months They report a 96% of success with only two recurrences. Since the fair results and low invasiveness of the method, the Authors propose the repeated alcoholization in the treatment of simple voluminous renal cysts.

[Echographic aspects of renal tuberculosis]. / Aspetti ecografici della T.B.C. renale.

In this study the Authors examine the utility of the ultrasonographic investigation in the preoperative evaluation of 22 patients submitted to nephrectomy for tubercular lesions, comparing the informations obtained from this procedure with the histologic report. The renal ultrasonography execute with a Toshiba 3.5 Mhz probe, has been utilized to value morphology, volume, parenchymal echostructure and hydronephrosis. According to the Author's series, the ultrasonography has shown a 100% sensitivity permitting to well value the presence of parenchymal lesions and hydronephrosis. As regards the tubercular renal injuries the ultrasonography is non-specific because it does not allow to have pathognomonic images. The results obtained from the U.S. are overlapping to the Results Related from the literature for abdominal CT. The Authors argue that U.S., rapid and economical investigation is an efficient complement to the urography for an exhaustive preoperative evaluation of patients suffering from renal Tuberculosis.

[Transvaginal echography in the study of urinary stress incontinence]. / L'ecografia trans-vaginale nello studio dell'incontinenza urinaria da sforzo.

Hypermobility of the bladder neck in response to increased intraabdominal pressure is one cause of stress urinary incontinence in women. Vaginal ultrasound (u.s.) is reliable and minimally invasive method for demonstrating bladder neck hypermobility. The Authors studied 50 women with S.U.I. and 40 with no history of S.U.I. measuring the distance from the bladder neck to the midline of the symphysis pubis (P.V.) and the angle between the BP line and the midline of the symphysis pubis (A.I.U.). The continent women were characterized by a median A.I.U. of 70 degrees and mean B.P. of 25.6 mm, at rest, a median A.I.U. of 80 degrees and a mean B.P. of 20 mm. at stress. The incontinent women were characterized by a median A.I.U. of 80 degrees and mean P.V. of 22.5 mm. at rest, and a median A.I.U. of 95 degrees and mean P.V. of 10 mm. at stress. There is a significant difference between the two groups. The Authors recommend the vaginal u.s. as reliable, practical, economical and patient accepted method to study the bladder neck mobility.

Spinal cord gliomas and hydrocephalus: utility of neuroendoscopy.

OBJECTIVE: The aim of this study is to report on the role of neuroendoscopy during the management of hydrocephalus that led to the diagnosis of intracranial tumoral dissemination and the subsequent finding of a spinal cord glioma. METHODS AND RESULTS: We present two children each with an intramedullary astrocytoma that presented initially with hydrocephalus without spinal cord symptoms. In both cases leptomeningeal gliomatous dissemination was asserted during routine endoscopy for the management of hydrocephalus. The diagnosis of a cervical and a lower thoracic intramedullary tumor was made soon after on magnetic resonance imaging. CONCLUSIONS: Spinal cord MRI with contrast should be considered initially in selected cases of hydrocephalus without evident diagnosis. The intraoperative diagnosis of gliomatous dissemination and secondary hydrocephalus due to unrecognized spinal cord gliomas was possible, in our experience, with the routine use of the neuroendoscope.

Campylobacter pylori gastritis: long term results of treatment with amoxycillin.

To evaluate the efficacy of amoxycillin in eradicating Campylobacter pylori, endoscopic biopsy specimens were taken from the antral mucosa of 40 children with gastritis before, immediately after, and (in 30 patients) three months after treatment. Immediately after treatment 34 patients (85%) no longer had the organism in the mucosa, and the gastritis had healed in 23 (58%). Three months later the infection had recurred in 22 of 30 patients (73%), and the gastritis had relapsed in all of them. Significantly more children in whom C pylori recurred had family histories of peptic ulcer disease. The results suggest that amoxycillin alone is ineffective in the long term treatment of C pylori gastritis.

Mucin-secreting cellular ependymoma: a light and electron microscopy study.

Mucin accumulation in ependymomas is thought to be limited to the myxopapillary variant and represents an important diagnostic feature. Similarly, signet-ring cells in ependymomas have been shown by electron microscopy to represent microrosette instead of mucin secretion. This study describes an infratentorial ependymoma largely composed of mucinous areas and signet-ring cells. The ependymal nature of mucin-secreting cells was confirmed by ultrastructural analysis. This case widens the variable spectrum of ependymal morphology. The value of electron microscopy in differentiating central nervous system neoplasms showing mucous secretion is stressed.

Transvaginal ultrasonography in the assessment of organic diseases of female urethra.

The current investigation aimed to check the effectiveness of transvaginal ultrasonography in the diagnosis of organic urethral diseases, comparing its results with those of conventional examinations (physical examination, voiding cystourethrography, pelvic ultrasonography, cystourethroscopy). Transvaginal ultrasonography was performed in 560 female patients with recurrent cystitis, dysuria, or palpable masses and diagnosed the following urethral diseases: 25 diverticula, seven stenoses, three carcinomas, two leiomyomas of periurethral tissue, and one incomplete duplex urethra. In our study transvaginal ultrasonography proved to be the most reliable diagnostic tool among imaging methods used.

The immunohistochemical detection of lymph node metastases from infiltrating lobular carcinoma of the breast.

Immunological markers improve specificity and accuracy of cell detection, therefore it is important to evaluate their usefulness in improving standard histological procedures. This study investigates whether immunocytochemical techniques increase the accuracy of detection, in axillary lymph nodes, of metastatic cells from infiltrating breast lobular carcinoma (ILC). Fifty cases of ILC reported to be node-negative were selected. New serial sections were cut from a total of 767 lymph nodes, stained with H&E and tested in immunoperoxidase (ABC procedure) with a conventional anti-Epithelial Membrane Antigen (EMA) serum, with a monoclonal raised against human milk fat globule membranes (HMFG-2) and with a monoclonal against 54 kd keratin. Metastases were detected immunocytochemically in 12 cases (24%); in five of these cases metastatic cells were also visible in serial H&E sections. Monoclonals offered no evident advantage over anti-EMA conventional antiserum. Immunocytochemical positivity alone is not sufficient evidence for metastatic invasion since macrophages occasionally appear EMA- and HMFG-2-positive (probably because of secondary incorporation of the antigen), and so an improvement in the accuracy of breast cancer metastatic cell detection in axillary lymph nodes requires a combined histo-immunological approach.

Production of monoclonal antibodies for the immunohistochemical detection of gastric carcinomas.

About 700 antibody-secreting hybrids were obtained by fusion of lymphocytes, (harvested from mice hyperimmunized with the human gastric carcinoma line KATO III) and P3-X63-Ag8-653 myeloma cells. Antibody specificity was screened in ELISA performed on glutaraldehyde-fixed cultured cells and on paraffin-embedded tissue sections stained with the method of avidin-biotin-peroxidase. When tested in ELISA, the monoclonal antibody produced by the hybrid clone BD-5 was found to bind only to the cell line used as immunogen, among the many neoplastic or normal human cell lines tested. When assayed on paraffin sections with the avidin-biotin-peroxidase method, the BD-5 monoclonal antibody stained gastric carcinomas, but not the normal mucosa. Pancreatic carcinomas were also stained, while the corresponding normal gland was not. The antibody strongly stained the normal colonic and small intestinal mucosa. Among the other normal or neoplastic tissues tested, a weak reactivity was observed only with some epithelial cells of the salivary glands and with some carcinoma cells of the uterus and of the lung. It is concluded that the BD-5 antibody reacts with an epitope normally present on intestinal mucosa, which, following neoplastic transformation, is ectopically expressed also on gastric and pancreatic carcinomas. This monoclonal could represent a useful reagent for histopathological diagnosis.
