[TSH, FT4 and T3T evaluation in normal and preterm hospitalized newborns].

UNLABELLED: Thyroid hormones are essential for foetus and newborn development. Preterm newborns present low levels for thyroid hormones. These low levels are related with disorder in psychomotor and neurological development. In the literature, several studies concerning newborns treated with thyroid hormone have been realized in different conditions; however, there is no consensus about preterm newborn supplementation benefit. OBJECTIVE: The aim of the study was to defined hormonal values used for normal and preterm newborns. MATERIAL AND METHODS: We reported TSH, T3T and T4L levels for 195 normal or preterm newborns, eutrophic or small for gestational age (SGA). RESULTS: A positive correlation was found between hormonal level and gestational age. This work allowed us to define a threshold for preterm newborn according to their gestational age. CONCLUSION: Owing to lack of consensus, those values are useful for clinical and biological follow-up of thyroid function for newborns at risk (SGA and preterm before 32 weeks) during the first year of life. Finally, it would be interesting to study systematic supplementation of thyroid hormone for those infants in a prospective study.

Attitudes towards menopause in a group of women followed in a public service for menopause counseling.

This preliminary study addressed some specific attitudes towards menopause, and behavioral styles in menopausal women. The study was conducted during the period January-May 1998 at the Menopausal Service of the Magenta Hospital (Milano) in 88 women, representing almost one half of the patients followed during that period; 43 women were treated with HRT. Some traits characterizing women's life during menopause were examined, such as presence of disturbing physical symptoms, changes in interests and discovery of new interests, and feelings of loss and uselessness. We used different psychological tests in order to evaluate anxiety and depression, in particular, the STAI (State-Trait Anxiety Inventory), the SDS (Self-rating Depression Scale), and 16 cartoon-like images representing stereotypes of menopause. The answers of our subjects showed high individual variation, with negative symptoms (e.g., hot flashes, memory loss) frequently associated with positive experiences (e.g., new hobbies, new life-styles). However, even the most frequent negative symptom (memory loss) was reported only by 70%. The experience of a change represented by menopause was described both in terms of objective change (e.g., weight increase, hot flashes, memory loss), and of subjective change (e.g., character, feeling of not being attractive, new life-styles). Treatment with HRT seems to reduce the onset of hot flashes considerably. The occurrence of anxious-depressive states was comparable to that observed in other studies; it was not associated with HRT, but rather to losses (loss of desire, memory loss, insomnia). In conclusion, menopause represents a transitional moment in which physical and psychological changes are generally integrated by the persons experiencing them. In order to preserve a good quality of life in menopause, it seems relevant to check memory loss and stabilize the mood in persons who are most "at risk" of psychological disease.

[Uretero-arterial fistula as a complication of vascular surgery].

Urinary fistulae between ureter and iliac arteries are very uncommon. A case of fistula connecting ureter and bypass between iliac and femoral arteries is reported. This kind of surgical complication, due to arterial lesion during coxo-femoral arthroprosthesis implant has never been reported in the literature.

[TB-test in the diagnosis of "closed" tuberculosis of the urinary tract. Preliminary study].

BACKGROUND: Tuberculosis (TBC) is a disease that is found throughout the world with a particularly high incidence in under developed countries. Genitourinary tuberculosis has been reported in 8-10% of all cases in developed countries and in 20% in Third World countries. This study aimed to describe a method of diagnosis applicable to so-called "closed" forms of tuberculosis affecting the urinary tract, namely those with negative results for KB bacteriological and culture assay, but in which suspected diagnosis based on clinical grounds and diagnostic procedures call for further analysis; these forms account for 10% of the total cases. METHODS: A prospective study was carried out in order to tritade the antigenic fraction A60 of the group of thermostable macromolecular antigens (TMA); the latter belong to the pool of liposoluble antigens forming the cell wall and represent the main component of tuberculin and purified protein derivative (PPD). The identification and assay of antigen A60, which can stimulate both the antibody and cell-mediated response, was performed using the ELISA method in order to identify IgG and IgM specific antibodies (TB-test). Twenty-nine patients were selected (11 males, 18 females) with a clinical history of recurrent symptomatic manifestations of upper and lower urinary tract infections resistant to common antibiotic treatment. Urinary tests showed that 96.5% of patients presented an acid urinary pH associated with pyuria, and the urographic imaging revealed calico/pyelic lesions of the excretory tracts. RESULTS: Seven patients (24%) showed a form of urinary TBC of an areactive type (AA) or with intermediate reactivity (RI.AI); six patients (20.64%) showed reactive TBC or in the process of resolution; fifteen patients (51.6%) were negative to the TB-test, and after one year's follow-up still showed no positivity to assays for Koch's bacillus. CONCLUSIONS: The authors affirm that the TB-test, a rapid and relatively inexpensive diagnostic method, is a valid aid for the diagnosis of "closed" forms of urinary tract TBC.

Ureteral injuries during gynecologic procedures.

The reported incidence of iatrogenic ureteral injuries ranges from 0.05 to 30%. These injuries are particularly secondary to gynecologic surgical procedures. Simple abdominal hysterectomy has proved to be the most common procedure leading to such injures. Because some ureteral injuries may be symptomless, leading to silent kidney loss, the incidence may be too low, and a figure of up to 2.5% after gynecologic operations has been suggested. The incidence continues to be about ten cases during abdominal surgery for one case during vaginal surgery. Different risk factors may influence the ureteral injuries rate. An operation at the pelvic brim, distorted anatomy, removal of the adnexa or of ovarian neoplasm, may facilitate the occurrence of an ureteral trauma. The management of ureteral trauma is positively influenced by an early recognition of the trauma. Conventional technique or ureteroneocystostomy or end to end anastomosis with ureteral stent to treat the injury proved successful. Extensive reconstruction draws upon the entire therapeutic armamentarium of the urologist. Surgical options mainly include creation of bladder tubes and autotransplantation. The most important factor influencing the management of ureteral injury is the presence of associated complications. Blandy et al. sustained to attempt repair of these complicated iatrogenic injuries as soon the diagnosis has been made.

[Association of leiomyosarcoma and bladder papillomatosis].

The authors report one case of leiomyosarcoma associated with the papillomatosis of the bladder. After reviewing the literature, in which the exceptional nature of such tumoral associations is underlined, as are the infrequency and marked malignancy of leiomyosarcomas of the bladder, the authors illustrate the pathological and clinical characteristics of this neoplastic disease and discuss the pathogenic theories concerning this association.

[Malignant non-functioning adrenal cortex carcinoma. Apropos of a case].

A rare case of non-functional carcinoma of adrenal cortex is reported. After a review of the relevant literature, clinical characteristics and diagnostic methods are discussed and surgical treatment and chemotherapy prescribed in this case outlined. Based on personal experience, limitations of diagnostic imaging technics are presented and the importance of conventional radiologic investigations (urography and selective arteriography) re-evaluated, while emphasizing the reciprocal complementarity of all these methods for exploration of retroperitoneal lesions.

[A rare cause of bladder neck obstruction: cervico-trigonal cysts. Report of 2 clinical cases].

Two rare cases of cervico-urethral obstructive lesions are described, illustrating two typical examples of the twofold pathogenic possibilities of the affection. The first patient had a probably congenital cervico-trigonal cyst due to a ureteral bud in the bladder wall. The second case presented different symptoms and signs, and this together with histology findings suggested an acquired nature of the lesion from cystic transformation of an infected glandular structure. The published literature is reviewed and diagnostic difficulties are emphasized, particularly differentiation from a prostate median lobe lesion.

[Pseudomyxoma peritonei associated with mucinous cystadenoma of the appendix].

The authors report a case of a male 86 years old patient with peritoneal pseudomyxoma associated to cystoadenoma of the appendix. Preoperative CT scan showed the presence of a mass in the appendiceal site containing a gelatinous fluid collection and calcifications. Notwithstanding, diagnosis of pseudomyxoma was preoperatively considered less probable due to the rarity of the affection and the advanced age. At laparatomy was revealed the presence of the large mass observed at CT scan, involving the caecum and occupying the retroperitoneal space along the ascending colon. Mucinous ascites was present without invasive mucinous implants in the peritoneum. Operation consisted in a right hemicolectomy with total removal of the retroperitoneal mass and evacuation of the mucinous ascites. Histology confirmed the clinical diagnosis of pseudomyxoma peritonei associated to cystoadenoma of the appendix. The case is of paradigmatic interest as being quite correspondent to the classical Ronnett's definition of pseudomyxoma: a clinicopathological entity characterized by mucinous ascites and non-invasive mucinous implants with a characteristic distribution and containing histologically benign mucinous epithelium derived from an appendiceal mucinous adenoma and having a benign course. According to such definition, the authors stress the importance of an appropriate classification of the observed cases of pseudomyxoma, under whose term is often collected a heterogeneous group of pathological lesions, in order to better evaluate the prognosis and treatment.
