Histological and immunohistochemical characterisation of uterine adenocarcinoma in an Asian elephant (Elephas Maximus).

A 56-year-old nulliparous female Asian elephant (Elephas maximus) living at the zoological garden of Naples (Italy), with a clinical history of recurrent colic, was found in agonal state and humane euthanasia was elected. At necropsy the uterine body was moderately increased in size and the lumen was reduced due to a poorly demarcated and infiltrative neoplasm. Furthermore, multiple, whitish, firm nodules were present in both lungs. Histological examination of the uterine mass revealed epithelial cells arranged in tubular or solid pattern infiltrating the endometrium and the muscular layer. Immunohistochemical examination showed immunoreactivity of neoplastic cells to oestrogen receptors antibody. Pulmonary lesions were histologically and immunohistochemically superimposable to the epithelial uterine neoplasm. A definitive diagnosis of uterine adenocarcinoma with pulmonary metastases was made.

Medición de los resultados estéticos y funcionales desde la perspectiva del paciente en rinoplastía: creación del instrumento nose-qol / Development of a new patient-reported outcome measure for rhinoplasty suergery: the Nose-QoL

Background: Instruments that assess the results of plastic surgery from patient's perspective allow a multidimensional evaluation of surgical results. Aim: To develop a new instrument to assess the functional and esthetic results of rhinoplasty from the point of view of the patient. Material and Methods: A conceptual framework about important results for nasal image was developed using information from in depth interviews to patients, focal groups with experts and interviews to esthetic surgeons and patients subjected to rhinoplasty. Results: Four patients and four plastic surgeons were interviewed. The three sub scales identified for the conceptual framework were quality of life, postoperative disability and pain and surgeon's objective evaluation scale. Five domains for quality of life were identified including nose size and form, self-image and esteem, third party perceptions and social relationships, nasal function and segmental nasal analysis. Conclusions: After completion of the psychometric assessment, the Nose-QoL instrument will become a valuable instrument to measure the impact and effectiveness of rhinoplasty from the patient's perspective.

Effects of season and superovulatory treatment on embryo yields in fine-wool Merinos maintained under field conditions.

The aim of the study was to assess the effects of superovulatory treatment (multiple FSH-dose vs single-shot FSH treatment) and seasonality on embryo yields in fine-wool Merino ewes. Treatment based on multiple FSH-dose consisted of 200 mg of FSH (Folltropin(®)) administered in seven decreasing doses. Single-shot treatment consisted of a single dose of 70 mg of FSH + eCG. In ewes treated with multiple FSH doses, number of recovered embryos was higher (6.0 ± 0.5 vs 3.5 ± 1.0), while non-fertilization rate was lower (12.8 ± 3.9 vs 40.3 ± 9.5) during the breeding season when compared to the non-breeding season (p < 0.05); although similar values of recovered Grades 1-2 embryos were observed between seasons. During the breeding season, proportion of responding ewes (98.1 vs 57.1%), ovulation rate (13.9 ± 0.8 vs 3.2 ± 1.2), recovered structures (7.9 ± 0.6 vs 1.7 ± 0.7), total recovered embryos (6.0 ± 0.5 vs 1.2 ± 0.6) and good-quality embryos (5.1 ± 0.5 vs 0.9 ± 0.6) were higher for the multiple FSH-dose treatment than for the single-shot protocol. In a similar way, in the non-breeding season, ovulation rate (11.3 ± 1.8 vs 6.0 ± 1.1) and recovered structures (6.6 ± 1.2 vs 2.7 ± 0.6) were higher for the multiple FSH injections protocol than those for the single-shot treatment, resulting in higher recovered Grades 1-2 embryos (3.2 ± 0.9 vs 1.4 ± 0.5). Current results indicate that seasonal anestrus affected embryo yields when applying multiple FSH-dose superovulatory treatment in Merino ewes, by decreasing the number of recovered embryos although the number of recovered good-quality embryos was not affected. During both seasons, multiple FSH injections produced higher ovarian response and number of viable embryos than the single-shot treatment.

Immunological and allergenic responses induced by latex fractions of Calotropis procera (Ait.) R.Br.

Immunological and allergenic responses against the latex of Calotropis procera were investigated in mice by oral and subcutaneous routes. The latex was fractionated according to water solubility and molecular size of its components. The fractions were named as non-dialyzable latex (NDL) corresponding to the major latex proteins, dialyzable latex (DL) corresponding to low molecular size substances and rubber latex (RL) which was highly insoluble in water. Anti-sera against these fractions were assayed for total IgG and IgA titration by ELISA and IgE and IgG(1) were quantified by passive cutaneous anaphylaxis (PCA) in rats and mice, respectively. None of the fractions induced antibodies level increases when mice received latex fractions by oral route and thus, did not develop allergy. Nonetheless, anti-sera of mice sensitized with NDL and RL by subcutaneous route displayed considerable immunological response while DL did not. IgG level augmented consistently against NDL and RL while IgA response was detected only to NDL. NDL and RL induced very strong PCA reactions suggesting that both fractions would contain latex substances involved in allergy. Furthermore, protein analysis of NDL and RL suggests that RL still retain residual proteins abundantly found in NDL that could explain its similar allergenic effect. No IgG(1) reaction was detected in any of the anti-sera tested. According to the results, the proteins of latex of Calotropis procera can provoke allergy by subcutaneous route. The NDL has previously shown to display anti-inflammatory and analgesic activities by intraperitoneal injection. It should be relevant to determine whether NDL could induce such activities when assayed by oral route since it was ineffective to induce allergy by this way.

AMS three-piece inflatable implants for erectile dysfunction: a long-term multi-institutional study in 200 consecutive patients.

OBJECTIVES: The aim of this study was to assess the longterm mechanical reliability of AMS (American Medical Systems) three-piece inflatable implants and their impact on patient-partner satisfaction in 200 consecutive patients with erectile dysfunction who underwent surgery in five different institutions. METHODS: Patient charts included in the study were collected and extensively assessed to record pre- and intraoperative data and postoperative complications. All patients and 120 partners were then seen often in the office at a mean follow-up of 59 months (range 6-130) and they were extensively questioned about function of the device and its impact on the couple's sexual life. RESULTS: At the long-term follow-up, 185 patients (92.5%) were still engaging in sexual intercourse with a mean frequency of 1.7/week. Patients and partners reported prosthetic erections as excellent, satisfactory or poor in 96 (48%), 100 (50%) and 4 (2%) cases, and in 20 (17%), 80 (66%) and 20 (17%) cases, respectively. Postoperative sexual activity was considered excellent, satisfactory or poor by 140 (70%), 44 (22%) and 16 (8%) patients and by 34 (28%), 81 (68%) and 5 (4%) partners, respectively. Reasons for patients' complaints included postoperative penile shortening in 60 (30%) cases and poor glandular engorgement in 40 (20%) cases. Partners' main complaint was unnaturalness of the prosthetic erection, a factor reported by 30 (25%) subjects. Complications requiring surgical exploration included infection in 12 patients (6%) and mechanical failure in 8 patients (4%). Kaplan-Meier estimates demonstrated significantly decreased mechanical survival for the Ultrex type of cylinders compared to the CX type of cylinders. CONCLUSIONS: AMS three-piece inflatable implants provide an overall patient and partner satisfaction rate of 92 and 96%, respectively. However, postoperative penile shortening and poor glandular engorgement were the causes of some complaints among the patient population as well as the unnaturalness of prosthetic erection among female partners. In the long-term, mechanically speaking, CX cylinders seem to be more reliable than the Ultrex ones.

Laparoscopic unroofing of adrenal cysts.

OBJECTIVES: This study was aimed to demonstrate the feasibility of laparoscopic conservative surgery of the adrenal gland in the treatment of adrenal cysts. METHODS: Two cases of laparoscopic decortication of symptomatic adrenal cysts with preservation of the adrenal parenchyma are presented. RESULTS: Surgery was uneventful in both cases and patients returned to preoperative activity within 10 days from the operation. At the 3-month follow-up, computerized tomography demonstrated the absence of any cystic recurrence and adrenal endocrine function was normal. These findings were confirmed at the 1-year follow-up by ultrasonography. CONCLUSIONS: Symptomatic adrenal cysts can be effectively and safely treated by laparoscopic unroofing, a minimally invasive procedure which leaves the nondiseased adrenal parenchyma intact.

Correction of stress urinary incontinence: laparoscopy combined with vaginal suturing.

The authors review the published techniques of laparoscopic colposuspension combined with vaginal suturing. Particular emphasis is given to their own technique, first published in 1992, and to that of Harewood (1993), which is similar. Both involve a Burch-like colposuspension using a technique similar to that of Gittes and Loughlin. This is possible looking inside the pelvis through a laparoscope and using a handle-needle. Published results are similar (about 70% success rate), but the authors point out that the Breda technique is simpler, cheaper, and less time consuming (only one trocar instead of three) and has had a longer follow-up (up to 3 years instead of 19 months). The authors review many other similar techniques reported between 1993 and 1995 with good results but based on rather limited experience. The conclusion is that the laparoscopic technique with vaginal suturing seems a promising way to approach stress urinary incontinence in the female patient.

[Laparoscopic surgery of stress urinary incontinence in women]. / Chirurgia laparoscopica dell'incontinenza urinaria da stress femminile.

The Authors carried out a literature review on stress urinary incontinence (SUI) treatment using laparoscopy or pelvioscopy. They report their experiences in using a pubo-vaginal percutaneous colposuspension assisted by pelvioscopy. Of 22 treated patients, there was a total correction of the incontinence in 15 patients. (68.12%) with a median follow-up of 18.6 months. They report also their first experience with the Retzius plasty of Manhes by laparoscopy (3/4 patients treated are continent, 1/4 has recurrent SUI during times of stress). They conclude that laparoscopy and pelvioscopy treatment can be valid alternatives to traditional surgery if made on selected patients.

Stage A1 prostate cancer: follow-up with digital rectal exploration, prostate markers, fine-needle aspiration, ultrasonographically guided needle biopsy and biopsies of the residual prostate with resectoscope.

From January 1985 to December 1990, we performed 921 TURP and 23 retropubic adenomectomies. In 70 patients (7.4%) histological examination revealed an incidental carcinoma of the prostate (stage A), 51 of which (72.8%) were A1 and 19 (27.2%) stage A2. In our classification A1 covers cases with < 3 G1 focal lesions [Boxer, 1977]. Thirteen of the A2 cases underwent radical prostatectomy: 1 pT1G1-2, 9 pT2G1-2, 3 pT3G2 (TNM 1978); the remaining 6 were given palliative treatment. The 51 stage A1 patients were recalled for follow-up evaluation, only 20 came for checking. They were reassessed by means of DRE, markers, prostate cytologic aspiration, echo-guided transperineal needle biopsy and resection of the prostatic cavity. Our experience seems to suggest that, if we define A1 as < 3 G1 chips or less, this stage is to be considered an incidental illness that seems not to require further treatment, but only a policy of surveillance with yearly markers, DRE and echo-guided needle biopsy.

Laparoscopic nephrectomy with vaginal delivery of the intact kidney.

The first case of laparoscopic nephrectomy in Italy is described. The patient was a 51-year-old woman with a small, nonfunctional, tuberculous left kidney. The organ, once detached from its lumbar site, was brought in to the pelvic cavity and extracted from the body via a posterior colpotomy. In this way, the integrity of the organ is preserved, hence, this could be the preferable route when dealing with a little kidney tumor in a woman.

Treatment of hydrocele: randomised prospective study of simple aspiration and sclerotherapy with tetracycline.

Following reports in the literature on the efficacy of tetracycline sclerotherapy in the treatment of hydroceles, we carried out a randomised prospective study of 45 patients (50 hydroceles), comparing simple evacuation with tetracycline sclerotherapy. The results revealed no statistically significant difference in the percentage of success between the 2 groups, but complications were more common in the patients treated with tetracycline. The good results reported by other authors in non-randomised studies are, therefore, not confirmed.

Pharmacological approach in the treatment of insulin resistance.

Insulin resistance syndromes are heterogeneous in either severity or mechanism. Many drugs have been shown to counteract various elements of insulin resistance. Some of them, by normalization of metabolic parameters, decrease insulin resistance induced by chronic hyperglycemia in diabetes. Insulin and, to some extent, sulfonylureas are in this group, but these drugs are not stricto sensu medication of insulin resistance. Some drugs sensitize peripheral tissues to the action of insulin. For instance, biguanides and thiazolidine-dione facilitate translocation to the membrane of glucose transporter in presence of insulin. Other compounds as vanadate or IGF-1 mimic some peripheral action of insulin. Finally, blockade of FFA oxidation by specific inhibitors (methylpalmoxyrate) can limit insulin resistance. In 1992, among these compounds, specific of insulin resistance, biguanides are mostly used. However, the efficacy of these drugs is moderate and limited to type 2 diabetes.

Nomogram for penile biothesiometry.

Three hundred and fifty men, aged between 17 and 80 years, with normal sexual anamnesis and without any neurological pathology, underwent finger (index) and penile biothesiometry using a biothesiometer. Tabular and graphical nomograms were obtained according to age and instrumental values. The use of the above-mentioned nomograms is an effective aid in detecting each individual case.

[Cost-benefit relationship between endoscopic resection (TURP) and open surgery (Millen) in prostatic hypertrophy ]. / Rapporto costi-benefici tra resezione endoscopica (TURP) e chirurgia a cielo aperto (Millin) nell'ipertrofia della prostata.

Evaluation of the cost/benefit relationship between TURP (50 cases) and Millin (30 cases). The factors considered are as follows: average post-operative hospitalization, average catheterisation time, average operation time, cost of materials, number of operators employed, number of transfused blood units. The post-operative hospitalization relating to the two kinds of operation varies considerably with a difference of 5.15 days less for the TURP, while the average catheterisation time doesn't seem to be affected. Blood transfusion was necessary in the 43.3% (0.75 unit/patient) of cases for the Millin compared to the 14% (0.26 unit/patient) for the TURP. Evaluation of economical advantages between TURP and Millin shows a relationship of 1:2.3 in favour for of TURP.

[Epididymitis in adults. Retrospective study of 110 cases]. / L'épididymite chez l'adulte. Etude rétrospective sur 110 cas.

A review was conducted of 110 cases of epididymitis, most of these patients (71.9%), especially those under 50 years of age, having negative urine cultures: this appears to confirm the high frequency of Chlamydia T infection in the age group 20 to 50 years when sexual activity is at its maximum. Urinary output was normal in 60 of 79 patients and urography exploration provided normal results in 69 of the 110 patients (63%), particularly in those under 50. It is concluded, therefore, that urography is not necessary in patients under 50 but remains necessary in those in older age groups.
