[Gallbladder carcinoma and laparoscopic cholecystectomy. An emergent problem].

BACKGROUND: Gallbladder cancer (GC) is reported in 1.5-3% of cholecystectomies. Since the introduction of laparoscopic surgery, cholecystectomies have increased and occult GC may therefore be more frequent. METHODS: Here we conduct a retrospective study on a series of 1200 LC performed between January 1991 and December 1998 at our Institution, to determine whether there was an increase in GC. We also evaluated the risk factors for this outcome and the possibilities of treatment, in case of unsuspected GC discovered after LC at histological examination. Seven cases of GC undiagnosed before surgery (0.6% of the study population) were submitted to LC (against 0.3% GC discovered after open surgery). The clinical course depended on the histopathologic stage of the cancer. RESULTS: After a median follow-up of 18 months (range 12-48), 2 pT1 patients were alive and well, 2 pT2 patients were alive and disease free (in 1 case after a surgical removal of a trocar site metastasis appeared 6 months after LC). The other 3 patients died, 2 (1 pT2 and 1 pT3) after an additional resection of the liver bed with lymph node dissection, due to peritoneal dissemination of the disease. In 2 cases we found a gallbladder polyp pre and intraoperatively, which proved to be a carcinoma. CONCLUSIONS: Undiagnosed GC is on the increase with the introduction of LC. Polypoid lesions of the gallbladder, age > 70 years: a long history of stones and a thickened gallbladder wall all represent significant risk factors. If one or more is present, examination of the gallbladder and a frozen section are recommended.

Clinical manifestations of gallstone disease: evidence from the multicenter Italian study on cholelithiasis (MICOL).

Despite the many efforts to delineate the clinical manifestations of gallbladder disease, the precise symptom complex associated with gallstones is still a matter of debate, and even the existence of gallstone-specific symptoms has been questioned. We carried out a large population-based cross-sectional study (MICOL) to identify symptoms significantly related to gallstones. Fourteen centers throughout Italy enrolled 29,504 subjects aged 30 to 69 years. All subjects were administered an ultrasonographic examination of the upper abdomen and a precoded questionnaire. All subjects were divided into 4 groups: 25,374 (86.0%) gallstone-free subjects (GF), 1,832 (6.2%) patients with gallstones not previously diagnosed (GNPD), 638 (2.2%) patients with gallstones previously diagnosed (GPD), 1,660 (5.6%) patients with a history of cholecystectomy for gallstones (CC). In logistic regression analysis, pain at epigastrium and, even more, pain at right hypocondrium were significantly associated with gallstones. For pain at right hypocondrium, this association progressively increased from GNPD (OR = 1.60, 95% CI = 0.97-2.65) to GPD (OR = 8.77, 95% CI = 5.27-14.61) to CC (OR = 59.40, 95% CI = 43.87-80.42). Absence of heartburn combined with right hypocondrium or epigastrium pain and intolerance to fried or fatty food were also significantly related to gallstones. We also found some pain characteristics significantly associated with gallstones, i.e., pain radiated to the right shoulder, forcing the patient to rest, occurring soon after meals or unrelated to meals, not relieved by bowel movements, and frequently accompanied by gallstone-related morbidities. We developed a probability tree reporting the cumulative probability of having gallstones for each combination of those symptoms and characteristics of pain significantly associated with gallstones. In conclusion, we have identified symptoms and signs significantly associated with gallstones. We have shown that there is an increase in frequency and severity of these symptoms and signs across the different stages of gallstone disease. We have proposed a complex of symptoms and signs significantly associated with gallstones that might help physicians in clinical decision making.

Resectoscopic treatment of uterus didelphys with unilateral imperforate vagina complicated by hematocolpos and hematometra: case report.

OBJECTIVE: To describe a technique for treating hematocolpos and hematometra in patients with uterus didelphys and unilateral imperforate vagina involving the use of resectoscopy under ultrasonographic control. DESIGN: Case report. SETTING: University hospital. PATIENT(S): A 13-year-old girl with uterus didelphys with unilateral hematometra, hematocolpos, and ipsilateral renal agenesis. The girl complained of severe abdominal pain, which appeared with each of her menses. INTERVENTION(S): The intervention was performed by a vaginoscopic approach to preserve the integrity of the hymen. The first incision on the vaginal wall was performed in correspondence with the hematocolpos under continuous ultrasonographic guidance with the use of a straight resectoscopic loop. Resection of the vaginal septum was continued with the use of an angled resectoscopic loop until almost complete excision of the septum was achieved. MAIN OUTCOME MEASURE(S): Clinical, echographic, and vaginoscopic findings before the operation and 2 and 6 months after the operation. RESULT(S): The surgical procedure was easy to perform. Almost complete excision of the septum was achieved with just a few passages of the resectoscope. Complete drainage of both the hematocolpos and the hematometra was confirmed by ultrasonography. The postoperative period was completely uneventful. Clinical and vaginoscopic evaluations 6 months after the operation confirmed the integrity of the hymen, the complete resolution of clinical symptoms, and the persistence of a large communication between the two vaginas. CONCLUSION(S): Resectoscopic excision under ultrasonographic guidance of the vaginal septum in a girl with uterus didelphys with unilateral hematometra and hematocolpos was effective and easy to perform, and it fully respected the integrity of the reproductive system.

Onychomycosis caused by Blastoschizomyces capitatus.

Blastoschizomyces capitatus was cultured from the nail of a healthy patient with onychomycosis. The identity of the isolate was initially established by standard methods and ultrastructural analysis and was verified by molecular probing. Strains ATCC 200929, ATCC 62963, and ATCC 62964 served as reference strains for these analyses. To our knowledge, this is the first case of nail infection secondary to paronychia caused by this organism reported in the English literature.

Increased systemic oxidative stress after elective endarterectomy: relation to vascular healing and remodeling.

It has been reported that systemic and local redox state may have an important role in the functional and organic changes characterizing the process of vascular response to injury. Carotid endarterectomy to remove atherosclerotic plaque is followed by a long lasting healing and remodeling process that can be carefully followed over time with noninvasive ultrasonography. Plasma vitamin C concentration and native LDL (n-LDL) content in lipid peroxides, vitamin E, beta-carotene, and lycopene as well as LDL susceptibility to peroxidation were assessed in 45 patients undergoing elective endarterectomy for internal carotid stenosis, at baseline, 24 hours, 3 and 15 days, and 1 month after surgery. Serial duplex scans were performed in all patients postoperatively and 3, 6, and 12 months. The changes in far wall thickness (FW) and % renarrowing from postoperatively to 12 months were used as remodeling indices. Plasma antioxidant vitamins and lag-phase showed a sharp and significant decrease during the first 24-hours after surgery remaining unchanged until the third day, whereas, an opposite trend was evidenced for n-LDL content in lipid peroxides and serum ceruloplasmin. After the third day all the parameters returned progressively to baseline within one month from endarterectomy. Interestingly, the n-LDL lipid peroxide content, the serum ceruloplasmin and the plasma vitamin C concentration, measured at 24 and 3 days from surgery, were significantly associated to the change in % renarrowing from postoperatively to 12 months. The higher the LDL content in lipid peroxides, the higher the serum level of ceruloplasmin, the lower the plasma content in vitamin C and the higher the % of vessel renarrowing. In conclusion, carotid endarterectomy with atherosclerotic plaque removal is associated with an acute and prolonged increase in systemic oxidative stress that influences vascular healing and late luminal loss.

Combined laparoscopic splenectomy and cholecystectomy for the treatment of hereditary spherocytosis: is it safe and effective?

Hereditary spherocytosis is the most common red blood cell membrane disorder and often is associated with hemolytic crisis and premature cholelithiasis. Splenectomy is the only effective therapy for this disorder and often it is performed in combination with cholecystectomy. Conventional surgery requires a wide upper abdominal incision for correct exposure of the gallbladder and spleen. Laparoscopic cholecystectomy and splenectomy have been performed safely worldwide. We report our experience with seven patients (one male and six female, average age 12 years) who underwent combined laparoscopic splenectomy and cholecystectomy for hereditary spherocytosis. The patient was placed in supine position and the procedure performed with a five-trocar technique. Cholecystectomy was performed first, then splenectomy was achieved and the spleen removed by morcellation into a retrieval bag (five cases) or via a 4- to 5-cm left subcostal incision (two cases). No patient required conversion to open technique or blood transfusion. The mean blood loss was 162 mL, mean operative time 207 minutes, mean spleen size 14.5 cm, and median postoperative hospital stay 4 days. No perioperative mortality or major complications occurred in our series. After a median follow-up of 18 months all patients showed sharp hematologic improvement. Despite the small number of cases, we consider the combined laparoscopic approach safe and effective for the treatment of hereditary spherocytosis.

[Endonasal dacryocystorhinostomy: a personal experience].

Stenosis of the naso-lachrymal duct as a consequence of acute or chronic inflammation, trauma or congenital malformation is a relatively frequent lachrymal duct pathology. The symptoms include epiphora and intermittent tumefaction of the medial ocular canthus, indicative of a deficiency in lachrymal drainage. If such conditions do not respond to medical treatment, lavage and transcanicular probe, surgery proves necessary. Modern techniques for endonasal surgery place the otologist in the forefront in the surgical treatment of this disorder. Endonasal dacryocystorhinostomy (DCR) is indeed a valid alternative to traditional extra-nasal surgery; once exclusively the domain of the ophthalmologist. However, it does require a certain expertise in micro-endoscopic surgery. In most cases sophisticated equipment is not required and the procedure can be performed with just a few instruments: electric knives, scalpel and Citelli forceps. Endonasal DCR makes skin incisions unnecessary and makes it possible to reveal, and possibly, correct, any sequela subsequent to traditional DCR such as ethmoidal rhino-sinusitis or the presence of adhesions. In the present work 67 patients--24 with recurrence after traditional surgery--underwent endonasal DCR within the last 22 months and with an average follow-up of one year. Surgery was successful in 90% of the cases.

Ocular disorders in users of H2 antagonists and of omeprazole.

We have conducted a cohort study of users of omeprazole and H(2) antagonists in Italy to investigate whether the peroral use of these drugs may be associated with an increased incidence of ocular disorders leading to loss of vision. We have used the Sistema Informativo Sanitario Regionale (SISR database) in Friuli-Venezia-Giulia to identify all subjects who received at least one prescription for cimetidine, famotidine, niperotidine, nizatidine, omeprazole, ranitidine or roxatidine between 1 January 1991 and 31 December 1994. We have identified all hospital admissions for serious vascular or inflammatory ocular disorders following any such prescription, reviewed and validated all medical records. There were 71,108 users of any of the study drugs, contributing a total of 101,827 person years of observation. Seven cases of serious eye disorders were identified, giving an annual incidence rate of 7/100,000 persons. By comparison to non-users, the incidence rate ratio for current users of all of the study drugs together was 0, with a 95% confidence interval of 0 to 2.1. By comparison to non-users, the incidence rate ratio for past users was 0.47 (95% CI: 0.06-2.4). Our data are consistent with previous studies and add weight to the general impression of the ocular safety of these drugs.

Plasma concentrations of progesterone are higher in the uterine artery than in the radial artery after vaginal administration of micronized progesterone in an oil-based solution to postmenopausal women.

OBJECTIVE: To verify the occurrence of preferential distribution of vaginally administered progesterone to the uterus compared with extrapelvic regions in vivo and in humans. DESIGN: Prospective clinical study. SETTING: University medical school. PATIENT(S): Twenty postmenopausal women undergoing transabdominal hysterectomy for benign pathologies. INTERVENTION(S): Forty-five minutes before surgery, the women received a single vaginal administration of an oil-based micronized progesterone (100 mg) solution currently available on the market for IM use. During the operation, parallel blood samples were drawn from the uterine and radial arteries. MAIN OUTCOME MEASURE(S): Plasma levels of progesterone were measured by RIA. RESULT(S): Mean (+/- SD) plasma levels of progesterone were significantly higher in the uterine artery than in the radial artery (9.75 +/- 3.21 vs. 5.12 +/- 2.06 ng/mL, respectively). CONCLUSION(S): Vaginal administration allows a preferential distribution of progesterone to the uterus, which confirms the existence of the so-called "first uterine pass effect."

Copper/zinc ratio and systemic oxidant load: effect of aging and aging-related degenerative diseases.

There is evidence that copper and zinc have pro-oxidant and antioxidant properties, respectively, so that their imbalance may be expected to condition oxidative stress status. Oxidative stress is relevant in aging and in age-related degenerative diseases. In this study, blood content of copper, zinc, and ceruloplasmin as well as of lipid peroxides were investigated in 81 healthy and 62 disabled octo-nonagenarians affected by chronic degenerative diseases, and in 81 healthy adults. Serum copper/zinc ratio and ceruloplasmin were significantly higher in the elderly than in the healthy adults. Moreover, all these parameters were significantly higher in the disabled than in the healthy elderly. Notably, the increased copper/zinc ratio found in healthy elderly was due to high copper values, whereas in the disabled, both high copper and low serum zinc concentrations were present. The copper/zinc ratio was significantly and positively related to systemic oxidative stress status in all groups. The higher the serum copper/zinc ratio the higher the lipid peroxides plasma content. We conclude that there is a strict relationship between copper/zinc ratio and systemic oxidant burden. Moreover, advanced age and, particularly, advanced age-related chronic degenerative diseases are associated with a significant increase in the copper/zinc ratio and systemic oxidative stress.

Cisplatin-vindesine-mitomycin (MVP) vs cisplatin-ifosfamide-vinorelbine (PIN) vs carboplatin-vinorelbine (CaN) in patients with advanced non-small-cell lung cancer (NSCLC): a FONICAP randomized phase II study. Italian Lung Cancer Task Force (FONICAP).

In the present multicentre randomized phase II trial, the activity and toxicity of three platinum-based combination regimens for the treatment of advanced non-small-cell lung cancer (NSCLC) were evaluated. The three regimens were: MVP (mitomycin-C 6 mg m(-2) on day 1, vindesine 3 mg m(-2) on days 1 and 15, and cisplatin 80 mg m(-2) on day 1 every 28 days), PIN (cisplatin 80 mg m(-2) day 1, ifosfamide 3 g m(-2) day 1 and vinorelbine 25 mg m(-2) day 1 and 8 every 21 days) and CaN (carboplatin 350 mg m(-2) day 1 and vinorelbine 25 mg m(-2) days 1 and 8 every 28 days). A total of 140 chemotherapy-naive patients entered the study; 49 patients were treated with MVP, 48 with PIN and 43 with CaN. Sixty-seven per cent of the patients had stage IV disease. Response rates, calculated on an 'intention to treat' basis, were as follows: MVP, 14.3% (95% CI 5.94-27.2%); PIN, 16.7% (95% CI 7.4-30.2%); and CaN, 14% (95% CI 5.3-27.9%). The overall median survivals were 256, 269 and 243 days for patients treated with MVP, PIN and CaN respectively. Myelosuppression was the most frequent toxicity: grade 3-4 leucopenia was observed in 14.3%, 25% and 18.6% of patients treated with MVP, PIN and CaN respectively. This multicentre phase II randomized trial shows that MVP, PIN and CaN can be administered on an outpatient basis with acceptable toxicities. Unfortunately, the three regimens showed an activity significantly lower than that reported in previous single-institution phase II trials.

Leucocyte interferon-alpha retreatment for chronic hepatitis C patients previously intolerant to other interferons.

The activity and tolerability of a retreatment cycle with leucocyte interferon-alpha (IFN-alpha) (6 million units (MU) three times weekly for 12 months) was evaluated in a group of 22 hepatitis C patients who had been intolerant to a previous course of lymphoblastoid IFN-alpha. Seven patients (31%) discontinued the new therapy owing to either a lack of response (six patients) or to severe leucopenia (one patient). Fifteen patients (68%) completed the 12-month treatment: all had a biochemical response and 10 (45%) also had disappearance of serum HCV RNA (complete response). Mild adverse reactions (fever, headaches and diarrhoea) were seen in these patients during retreatment. After 12 months of follow-up, 11 patients (50%) still maintained the biochemical response (long-term response); seven of these patients (32%) were also negative for serum HCV RNA. Biochemical and complete responses, at the end of both treatment and follow-up, were similar to those seen with lymphoblastoid IFN-alpha. The full dose of leucocyte IFN-alpha, when used in patients previously intolerant to the same dosage of lymphoblastoid IFN-alpha, was better tolerated: only one of the 15 patients who completed the 12-month treatment had a severe adverse event leading to withdrawal vs 22 of 68 patients treated with lymphoblastoid IFN-alpha. Furthermore, there were no manifestations of serological or clinical autoimmunity caused by leucocyte IFN-alpha, even in patients with autoantibodies associated with previous IFN therapy.

A nosocomial cluster of Candida inconspicua infections in patients with hematological malignancies.

Candida inconspicua was recovered from three patients with hematological malignancies. Two patients had intravenous-catheter-associated fungemia, whereas the third had fungal hepatitis. The three cases of infection occurred over a period of 1 month in patients staying in adjacent single rooms. In vitro susceptibility testing of fungal strains showed all isolates to be resistant to fluconazole, with MICs greater than 32 microg/ml. All of the strains had identical DNA restriction profiles and randomly amplified polymorphic DNA fingerprints. These data suggest a nosocomially acquired infection emanating from a common source within the hospital environment.

Arterial disease in dipper and nondipper hypertensive patients.

Carotid artery and small vessel structural changes were evaluated in 45 dipper and 45 nondipper hypertensive subjects matched for sex, age, body mass index, smoking habit, and serum lipids. Patients underwent carotid ultrasonography to evaluate lumen diameter, intima-media thickness, cross-sectional area, and atherosclerotic plaques, and plethysmographic examination to record minimum forearm vascular resistance. In the whole study population, carotid cross-sectional area and prevalence of atherosclerotic plaques tended to be higher in nondippers than in dippers (19.9 +/- 6.0 v 17.5 +/- 6.1 mm2, P = .07, and 40% v 26%, P = .18), whereas intima-media thickness and minimum forearm vascular resistance were significantly higher in nondippers than in dippers (0.89 +/- 0.12 v 0.8 +/- 0.15 mm, P < .02, and 2.53 +/- 0.3 v 2.34 +/- 0.3 arbitrary resistance units (RU), P < .02). When gender was taken into account, different results were obtained in men and women. In men, vascular characteristics were not significantly different between dippers and nondippers. In women, carotid cross-sectional area and prevalence of atherosclerotic plaques tended to be higher in nondippers than in dippers (18.3 +/- 4.9 v 15.5 +/- 4.5 mm2, P = .06, and 40% v 15%, P = .15), and intima-media thickness and minimum forearm vascular resistance were significantly higher in nondippers than in dippers both before (0.84 +/- 0.1 v 0.73 +/- 0.1 mm, P < .01, and 2.38 +/- 0.3 v 2.16 +/- 0.2 RU, P < .01) and after adjustment for 24-h blood pressure. In conclusion, our data suggest that the progression of vascular disease may be differently affected in the two sexes by a different circadian blood pressure profile.

White-coat resistant hypertension.

The aim of this study was to evaluate whether sustained hypertensives with high clinic blood pressure, despite multiple drug treatment, show a true resistant hypertension or a "white-coat effect," and whether the pretreatment white-coat effect is maintained despite pharmacological therapy. The occurrence of resistant hypertension was determined in 250 consecutive essential hypertensives who had had an ambulatory blood pressure monitoring before treatment assignment. Twenty-seven of 250 hypertensives with persistently high clinic blood pressure despite 3 months of adequate pharmacological therapy underwent further ambulatory blood pressure monitoring. Using our internal standards, seven patients had a true resistant hypertension whereas 20 subjects showed a large white-coat effect (white-coat resistant hypertension), ie, high clinic blood pressure (> 140/90) but "normal" ambulatory daytime (< 139/90 mm Hg) and 24 h (135/85 mm Hg) blood pressure. Using other cutoff points for ambulatory blood pressure, 134/90 and 135/85 mm Hg for daytime blood pressure, 10 and 13 patients, respectively, were reclassified as true resistant hypertensives and 17 and 14, respectively, were white-coat resistant hypertensives. Interestingly, in white-coat resistant hypertensives the large differences between clinic and ambulatory daytime blood pressure (white-coat effect), recorded before treatment assignment, were not affected by drugs and remained constant over time. Left ventricular mass index in white-coat resistant hypertensives was significantly lower than in truly resistant hypertensives, suggesting that prognosis could differ between these groups. In this study, using either our internal standards or some other cutoffs reported in the literature, the white-coat phenomenon was an important cause of resistant hypertension. The use of ambulatory blood pressure monitoring in these patients may avoid misdiagnosis of resistant hypertension, unnecessary overtreatment, and expensive procedures to look for possible secondary hypertension.

Eosinophilic ileocolitis by Enterobius vermicularis: a description of two rare cases.

BACKGROUND: Human enterobiasis is usually mild. Occasionally, however, an "ectopic" disease may occur with a more severe course. Two rare cases of eosinophilic ileocolitis due to Enterobius vermicularis infection are reported here. CASE REPORTS: Case n degree 1 was 46 years old, presenting with fever and bloody diarrhoea. Blood eosinophilia was present. Stool microscopy demonstrated red blood cells and leukocytes. A 2 mm long worm with bilateral cervical wings was found in wet-mount preparations of faecal samples. The Scotch tape test was positive for Enterobius vermicularis eggs. Colon biopsy specimens showed massive eosinophilic infiltration and a typical pinworm section overlying the infiltrated mucosa. Case n degree 2 was a 24-year-old, anti-HIV negative homosexual, presenting with watery diarrhoea. Tests for malabsorption were negative. Three mm long adult male E. vermicularis were found on stool microscopy. Biopsy specimens from the colon showed eosinophilic infiltration. In both cases a 200 mg/day course of oral mebendazole eliminated the symptoms within 3 days. CONCLUSIONS: In these two cases the clinical presentation of enterobiasis was atypical. A common finding was the eosinophilic infiltration of bowel mucosa, although it is still uncertain whether the worm per se may induce mast cell degranulation and eosinophil activation. Nevertheless, the possibility of Enterobius vermicularis infection should be considered in the presence of eosinophilic ileocolitis.
