[Neoplasms of the sigmoid incarcerated in inguinal hernia (case report and review of the literature)].

The authors consider the association of colonic neoplasia and hernia of abdominal wall. Such association, although not so frequent, was formerly remarked in literature 23 times; with the personal casuistic contribution of the authors, who recently observed a case thereof in an old patient woman, such remarks amount to 24. The authors describe the case they have the opportunity to observe, and report the experience of the other authors thereabout, through a careful reviewing of the literature starting from 1930 up to our time.

Echotomography in unilateral renal disease.

A review of about 300 patients with unilateral renal disease shows that echography is valuable for a correct diagnosis in numerous cases. The authors emphasize the role of A-B mode ultrasonographic scanning in the exploration of IVP nonvisualized kidneys, renal trauma, and other disorders.

Growth hormone secretion in Prader-Willi syndrome.

Prader-Willi Syndrome (PWS) is a multisystem defect characterized by obesity, hypogenitalism and short stature for genetic background. Low GH serum levels have been found in patients with PWS and were related to a hypothalamic-pituitary dysfunction. We studied spontaneous nocturnal GH secretion and GH-response to provocative tests in five patients affected by PWS. We observed in three of them (Group A) abnormally low GH and IGF-1 serum levels. In the other two patients (Group B) GH secretion and IGF-1 serum levels were normal. In all patients no thyroid dysfunction was observed. These data might suggest the presence of two different subgroups of patients affected by PWS, from an endocrinological point of view. An abnormally low GH secretion would be evident only in a subgroup of patients, which appears to be normal in the remaining patients. This casistic is small in number, but if our data will be confirmed by more extensive studies it may be possible to identify a specific population of PWS patients who could benefit from recombinant GH-therapy.

Urinary tract infection in full-term newborn infants: value of urine culture by bag specimen collection.

OBJECTIVE: To evaluate the efficacy of urine culture by bag specimen for the detection of neonatal urinary tract infection in full-term newborn infants. Retrospective study (1997) including full-term newborn infants having a positive urine culture (> 100,000 CFU/ml) by bag specimen collection. The urinary tract infection diagnosis was confirmed by positive urine culture (suprapubic bladder aspiration method). The select cases were divided into three groups, according to newborn infant age at the bag specimen collection: GI (< 48 h, n = 17), GII (48 h to 7 d, n = 35) and GIII (> 7 d, n = 9). Sixty one full-term newborn infants were studied (5.1% of total infants). The diagnosis was confirmed on 19/61 (31.1%) of full-term infants born alive. Distribution among the groups was: GI = 2/17 (11.8%), GII = 10/35 (28.6%), and GIII = 7/9 (77.7%). The most relevant clinical symptoms were: fever (GI--100%, GII--91.4%) and weight loss (GI--35.3%, GII--45.7%). Urine culture results for specimens collected by suprapubic aspiration were: E. coli GI (100%), GII (40%) and GIII (28.6%), E. faecalis GI (30%), Staphylococcus coagulase-negative GII (20%) and GIII (42.8%), and Staphylococcus aureus GII (10%). Correlation between positive urine culture collection (bag specimen method) and urinary tract infection diagnosis, using relative risk analysis, produced the following results: GI = 0.30 (CI 95% 0.08-1.15), GII = 0.51 (CI 95% 0.25-1.06) and GIII = 3.31 (CI 95% 1.8-6.06). The most frequent urinary tract infection clinical signs in the first week were fever and weight loss, while non-specific symptomatology occurred later. E. coli was most frequent infectious agent, although from the 7th day of life, staphylococcus was noted. The urine culture (bag specimen method) was effective in detecting urinary tract infection only after the 7th day of life.

Urinary tract infection in full-term newborn infants: risk factor analysis.

OBJECTIVE: To analyze the correlation of risk factors to the occurrence of urinary tract infection in full-term newborn infants. PATIENTS AND METHODS: Retrospective study (1997) including full-term infants having a positive urine culture by bag specimen. Urine collection was based on: fever, weight loss > 10% of birth weight, nonspecific symptoms (feeding intolerance, failure to thrive, hypoactivity, debilitate suction, irritability), or renal and urinary tract malformations. In these cases, another urine culture by suprapubic bladder aspiration was collected to confirm the diagnosis. To compare and validate the risk factors in each group, the selected cases were divided into two groups: Group I - positive urine culture by bag specimen collection and negative urine culture by suprapubic aspiration, and Group II - positive urine culture by bag specimen collection and positive urine culture by suprapubic aspiration. RESULTS: Sixty one infants were studied, Group I, n = 42 (68.9%) and Group II, n = 19 (31.1%). The selected risk factors (associated infectious diseases, use of broad-spectrum antibiotics, renal and urinary tract malformations, mechanical ventilation, parenteral nutrition and intravascular catheter) were more frequent in Group II (p<0.05). Through relative risk analysis, risk factors were, in decreasing importance: parenteral nutrition, intravascular catheter, associated infectious diseases, use of broad-spectrum antibiotics, mechanical ventilation, and renal and urinary tract malformations. CONCLUSION: The results showed that parenteral nutrition, intravascular catheter, and associated infectious diseases contributed to increase the frequency of neonatal urinary tract infection, and in the presence of more than one risk factor, the occurrence of urinary tract infection rose up to 11 times.

Advanced non-small cell lung cancer in the elderly: effective and well tolerated weekly gemcitabine and cisplatin regimen. A pilot study.

BACKGROUND: The frequency of advanced non-small cell lung cancer (NSCLC) increases with age and more effective and less toxic chemotherapy schedules are needed in elderly patients. Cisplatin-based regimens are considered the best treatment for advanced NSCLC, although they produce only a modest advantage in overall survival with considerable toxicity. METHODS: In the present study the activity and toxicity of a weekly gemcitabine and cisplatin schedule was evaluated in a small group of advanced NSCLC patients aged 68 years or more. Treatment consisted of gemcitabine 1000 mg/m2 i.v. and cisplatin 35 mg/m2 i.v., both given weekly on days 1, 8, 15 followed by 1 week of rest. RESULTS: Fifteen previously untreated patients entered the study; their median age was 72 years (range 68-76). One hundred and sixteen weekly administrations were delivered. The median dose-intensity was 614.5 mg/m2 per week for gemcitabine (82%) and 21 mg/m2 per week for cisplatin (80%). All the 15 patients were evaluable for response and toxicity. The overall response rate was 40% [95% CI = 16-68%]. The main toxicity was WHO grade III-IV thrombocytopenia that was recorded in 6 patients (40%). Other major toxicities were very low and no treatment-related deaths were reported. CONCLUSIONS: This schedule appears to be active, to have a favourable toxicity profile and can be considered in advanced NSCLC elderly patients. Of interest, the patients enrolled received high dose intensities of both drugs.

[Paraneoplastic syndromes: a review].

Modern oncology often obtains good results against earlier neoplasms, whilst it's still in difficulties against the advanced ones. The knowledge of paraneoplastic syndromes is crucial both to cure patients and to do an earlier diagnosis. When we recognize a paraneoplastic syndrome that comes before the clinic beginning of a neoplasm, perhaps we save a life. This review discusses all the main paraneoplastic syndromes, focusing mainly on their clinical aspect and reminding the most commonly associated cancers.

[Turner's phenotype and diagnosis of Noonan's syndrome].

The Authors describe two cases of Noonan's Syndrome (Turner phenotype and normal Karyotype), underlining the necessity of a differential diagnosis with the "True" Syndrome of Turner, for the presence, in the latter, of a non development of the height, weight and phenotype, which moves away from the standard much. While on the contrary in the Noonan's syndrome both the sexual development and the evolution of the height and weight may be normal and in the latter syndrome, so, the attention of the Doctors has to be turned prevalently to the congenital cardiopathy (almost always stenosis of the pulmonary artery), which can also impair the life of the patient.

[Results of a screening project for congenital hypothyroidism in 4 years of experience].

A screening program for congenital hypothyroidism has been starting in Siena since November, 1977 with the Guthrie's test for PKU. According to the recommendations of the Committee of the European Thyroid Association the program were performed on capillary blood samples collected between the fourth and sixth days after birth on an adsorbent paper. The screening began with the measurement of T4 RIA (up to May, 1980), and T4 and TSH RIA (from may, 1980, to december, 1981). At december, 1981, 23.693 newborns have been screened. The recall rate was 2,5% up to may, 1980, and 0,11% from may, 1980 to december, 1981. Ten newborns with congenital hypothyroidism have been detected; the incidence is one in 2.400 live births. There were no cases of transient hypothyroidism and no cases of TBG deficiency. All patients are treated before the age of one month. The diagnosis is confirmed in seven cases at one year of life after stopterapy for one month. Our program confirm the high incidence of congenital hypothyroidism. Clinical control, based on physical and psychomotor development testing in seven patients treated confirmed that all infants are normal.

[Empty sella syndrome: a cause of GH deficiency?].

A deficiency of growth hormone (GH) was detected in a male child with "empty sella syndrome" (ESS). Association between ESS and defeciences of pituitary hormones has been previously reported in adult subjects. It seems likely that GH deficiency is be related to ESS in the case described in this paper. An appropriate evaluation of the endocrine system seems suitable in this condition, since ESS in childhood is not to be regarded only from neuroradiologic point of view.

[Imaging technics in the indications for laparoscopic cholecystectomy. Echotomography and cholangiography compared].

March 1991 through October 1992, in the Clinica Chirurgica II of the Bologna University, 59 patients were submitted to laparoscopic cholecystectomy; the age range was 25 to 76 years and the mean 50 years. In no patient stones bigger than 35 mm were observed and 31% of the subjects were treated with litholysis before surgery. Fifty-eight patients were affected with single or multiple cholelithiasis, 1 had adenomyomatosis and 4 patients had associated choledocholithiasis treated with preoperative ERCP. Both US and cholangiography were performed to detect absolute contraindications--e.g., acute cholecystitis, cholangitis, peritonitis and cirrhosis--or relative contraindications--e.g., choledocholithiasis, > 5 mm stones and short cystic duct. US proved to be more sensitive than cholangiography to assess the number of stones and gallbladder wall thickness and to diagnose acute cholecystitis or scleroatrophic gallbladder, but it appeared to be less reliable in case of choledocholithiasis, where cholangiography was the technique of choice, and in possible anatomical variations--e.g., short cystic duct--which must be detected before laparoscopic cholecystectomy. Cholangiography appeared to be rather inadequate to study cholelithiasis when associated with functional gallbladder exclusion (as it happened in 17% of our patients). Intraoperative cholangiography was performed on 2 patients only, because their obesity hindered the preoperative study. In conclusion, the need is stressed of combining US and cholangiography for the accurate preoperative evaluation of gallbladder stones patients.
