Does surgical timing affect the rapidity of recovery in deep pain-entire non-ambulatory dogs with thoracolumbar intervertebral disk extrusion?

OBJECTIVE

To investigate whether the delay between onset of neurological signs and spinal cord decompression affects the time to recovery in non-ambulatory paraparetic/paraplegic dogs with deep pain perception affected by thoracolumbar intervertebral disc extrusion.

MATERIALS AND METHODS

Data on non-ambulatory dogs with preserved deep pain perception in both hindlimbs and surgically treated for thoracolumbar intervertebral disc extrusion were prospectively collected from three referral hospitals. Cox proportional hazards regression was used to explore the relationship of time until restoration of independent ambulation with age, weight, preoperative use of anti-inflammatory drugs, delay between onset of inability to walk and arrival at the clinic, time between presentation and spinal surgery and surgery time.

RESULTS

One hundred and fifty-one dogs were included. Median time from admission to surgery, including imaging, was 180 (interquartile range, 65.4 to 240) minutes. All dogs were operated within 72 hours. Follow-up was available for all 151 dogs and ranged from 1 to 21 months. All but three dogs, which were all grade IV at presentation, recovered the ability to ambulate. In both univariable and multivariable models, only duration of surgery and neurological (Frankel) grade at presentation were significantly associated with the rapidity of recovery of ambulation.

CLINICAL SIGNIFICANCE

Delay between onset of clinical signs and presentation and time between presentation and spinal surgery was not associated with the rapidity of recovery of ambulation in dogs surgically treated for thoracolumbar intervertebral disc extrusion. These results should be evaluated in the context of a limited range of delay since only 14.5% dogs had a delay ≥6.5 hours. Duration of surgery and neurological grade at presentation were significantly associated with rapidity of recovery of ambulation.

Acroangiodermatitis mimicking Kaposi's sarcoma in an HIV-positive man

Kaposi's sarcoma (KS) is the commonest human immunodeficiency virus (HIV)-related malignancy with its characteristic cutaneous morphological appearance and histopathological features. However, it can be simulated by other co-morbid opportunistic infections and unrelated dermatological conditions. We describe such a case of acroangiodermatitis in an HIV co-infected man, based on exclusion of KS histologically and the absence of human herpesvirus 8, the causative agent of KS.

Early- and late-onset psoriasis: a cross-sectional clinical and immunocytochemical investigation

BACKGROUND

There is accumulating evidence that early-onset psoriasis (EOP; presenting at or before 40 years of age) and late-onset psoriasis (LOP; presenting after 40 years of age) are different diseases.

OBJECTIVES

We aimed to identify potential clinical and immunocytochemical differences between EOP and LOP.

METHODS

We assessed immunocytochemistry in involved (PP) skin and uninvolved skin (n = 31) and demographics, psoriasis phenotype and psychological parameters (n = 340) in a cross-sectional study.

RESULTS

Immunocytochemistry revealed (17 EOP, 14 LOP) a greater lymphocytic infiltrate in PP skin of EOP compared with LOP (P = 0·03), with a higher epidermal CD4⁺ : CD8⁺ ratio in LOP (1·3) compared with EOP (0·5) (P = 0·002). In 340 patients with psoriasis (278 EOP, 62 LOP), we found an association with a positive first or second degree family history of psoriasis [62·0% vs. 35·6%, adjusted odds ratio (OR) 8·32, 95% confidence interval (CI) 1·90-36·52] and a higher likelihood of having parents with EOP (adjusted OR 10·34, 95% CI 1·32-81·83) in the EOP group. Patients with EOP were more likely to have received biological therapy (13·3% EOP vs. 3·5% LOP, P = 0·042), while patients with LOP had a higher likelihood of having type 2 diabetes (adjusted OR 3·43, 95% CI 1·004-11·691) and autoimmune thyroiditis (adjusted OR 5·05, 95% CI 1·62-15·7). Patients with LOP also had greater anxiety than patients with EOP (mean Hospital Anxiety and Depression Scale-A score LOP 8 ± 5, EOP 5 ± 5; P = 0·006).

CONCLUSIONS

Our findings provide further evidence for the difference between EOP and LOP.

Suspected exercise-induced seizures in a young dog

A 12-month-old female neutered crossbreed was referred for investigation of seizure-like episodes occurring only at intense exercise. Thorough medical, neurological and cardiac investigations were performed and excluded the most commonly known causes of seizure-like activity. The dog was fitted with an ambulatory electrocardiography device and underwent another exercise-induced seizure. The electrocardiogram during the episode revealed a sinus tachycardia at approximately 300 beats/minute. A video recording of the episode revealed generalised tonic clonic limb activity with jaw chomping and frothing at the mouth typical of seizure activity. Antiepileptic medications were not prescribed and the owner was advised not to exercise the dog intensely. The dog responded well and did not seizure after 12 months of mild-moderate off-lead exercise. As all the seizures in this case were triggered by intense physical activity, it is suggested that this may be a new form of reflex seizure activity.

Digital acrometastases as first sign of hepatocellular carcinoma

Digital acrometastases as a primary presentation of hepatocellular carcinoma (HCC) is rare. A 66-year-old man with no history of malignancy presented to the plastic surgery department with two skin lesions, one on the bridge of his nose and one on distal phalanx of left little finger. A working diagnosis of cutaneous metastases was made. Immediately prior to admission for excision of these lesions he was admitted with right upper quadrant pain and a jaundiced discolouration of the skin. The lesions were excised as planned and histopathological examination revealed metastatic HCC. A subsequent magnetic resonance imaging showed a lobulated mass consistent with primary HCC.

Syringosubarachnoid shunt as a management for syringohydromyelia in dogs

OBJECTIVE

To evaluate retrospectively the efficacy of syringosubarachnoid shunt for the management of syringohydromyelia/syringomyelia.

METHODS

Eleven dogs diagnosed with syringohydromyelia/syringomyelia by magnetic resonance imaging associated with Chiari-like malformation underwent placement of a syringosubarachnoid shunt at the cervical (nine dogs) or lumbar (two dogs) spinal cord. In one dog, a suboccipital decompression (foramen magnum decompression) was performed 4 months before inserting a syringosubarachnoid shunt. All dogs were evaluated neurologically a few hours after surgery, 2 weeks and 6 months postoperatively. Retrospectively, cases were assigned a preoperative and postoperative pain score.

RESULTS

There were no intra- or peri-operative complications. One dog (9%) was euthanased 5 weeks after surgery. Progressive neurological improvement was observed in nine dogs (81·8%) 2 weeks and 6 months postoperatively. No clinical improvement was seen in another dog (9%). One dog (9%) had replacement of the syringosubarachnoid shunt. Seven dogs (63·6%) were still alive 1 to 4 years (mean, 2·6 years) after surgery.

CLINICAL SIGNIFICANCE

Placement of a syringosubarachnoid shunt in the presence of a sufficiently large syrinx appears to be beneficial in dogs with Chiari-like malformation and associated syringohydromyelia/syringomyelia.

Is phlebography crucial in Tauber varicocele sclerotherapy?

Objectives.

Our aim was to discover whether it is possible to eliminate retrograde phlebography in the treatment of varicocele by using Tauber procedure.

Methods.

We treated 102 consecutive left varicocele patients between November 2003 and May 2007. In 72 patients (Group A) we used the Tauber procedure, without performing preliminary retrograde phlebography, and injecting saline solution instead of contrast medium; in 30 patients (Group B) we performed the standard Tauber procedure. We followed up with scrotal color Doppler Ultrasonography and spermograms at 6 months.

Results.

The patients who underwent the Tauber procedure without phlebography (Group A) obtained results similar to those treated with phlebography (Group B). With our technique, surgical time and costs are reduced and, most importantly, exposure to radiation is avoided.

Conclusions.

We believe that Tauber procedure for the treatment of varicocele can be performed without retrograde phlebography.

Spontaneous Rupture of the Kidney

The rupture of the kidney with the formation of an extracapsular hematoma in the renal cavity but no evidence of external trauma or other obvious renal cause, is an uncommon finding, most often requiring urgent surgery.

An underlying renal pathology, often a renal tumor, should always be suspected.

This article describes the case of a 57-year-old male patient who was admitted for severe left flank pain and presented with signs of peritonism, microscopic hematuria and low hemoglobin levels; an emergency left subcostal laparotomy was performed, with removal of the hematoma and enucleation of a partially open mid-renal mass; the kidney was spared.

Histology showed a WHO type I, Fuhrman grade 2, papillary renal cell carcinoma.

The article deals further with frequency, presentation, type and treatment of the pathology underlying the spontaneous rupture of the kidney, particularly with regard to renal carcinoma.

Successful aging in centenarians: myths and reality

The term "successful aging" appeared in the first issue of "The Gerontologist" in 1961. During the successive years, this expression has changed its meaning. Nowadays, successful aging means "absence of diseases and disabilities, maintenance of high levels of physical and cognitive abilities, preservation of the social and productive activities". It has become a common opinion that the centenarians may represent the prototypes of the successful aging. This motivated our work to study the clinical, psychical, and functional aspects in a centenarian group, verifying the real autonomy, instrumental capacities, and working abilities. Our study pool consisted of 602 centenarians, who were also subjects of then epidemiological studies of the Italian Multicenter Studies on Centenarians (IMUSCE). All subjects underwent a clinical-anamnestic evaluation, cognitive-functional tests by means of the mini mental state examination (MMSE), the independence index in activities of daily living (ADL), the instrumental activities of daily living (IADL) scale. The centenarians were classified in three groups, according to the criteria elaborated previously by us, based on their psychophysical status and autonomy, as follows. Group A: centenarians in good health status; Group B: centenarians in an intermediate health status. Group C: centenarians in bad health status. Group A represented 20.0% of the total pool, Group B amounted to 33.4%, and the Group C was 46.6%. The centenarians of Group A presented normal ADL values, and 47.9% of them were autosufficient in all functions; 5.7% of them were independent in all IADL items. These data confirm that the centenarians of Group A are free of invalidating chronic diseases, are autonomous, maintain good physical and cognitive capacities, however, have not maintained any social or productive activities. Therefore, they cannot be considered as prototypes of successful aging.

Percutaneous Sclerotherapy of Giant Benign Renal Cyst

We report a case of giant benign renal cyst that was treated with percutaneous aspiration and sclerotherapy using 95% alcohol. A 8F catheter was inserted into the cyst under ultrasonographic (US) guidance, and was then left in place to drain the cyst contents (approximately 4 L). A gravity sinogram showed no connections between the cyst and the collecting system. The alcohol treatment involved repeated injections of decreasing amounts of alcohol according with US measurement of cystic volume. The patient's symptoms resolved and cyst drainage stopped after 3 successive days of therapy. Follow-up ultrasound studies showed a 3.5 cm residual cystic wall only.

Preoperative Prediction of Pathological Stage by Quantitative Histology in 102 Patients with Prostate Cancer (PCa) and Serum PSA ≤10 ng/mL

Purpose. To find a predictor of extraprostatic extension in clinically localized prostate cancer (PCa), preoperative ultrasound-guided prostate needle biopsies and clinicopathological data were reviewed.

Materials and Methods

102 consecutive patients (median age 63 years) with serum PSA ≤10 ng/mL who underwent radical retropubic prostatectomy were included. Preoperative prostate biopsies according to an extended protocol were performed and whole-mount prostatectomy specimens were processed. One or more of the following biopsy variables were considered predictive of locally andvanced PCa: more than 2/12 cancer-positive cores, total percentage of cancer (TPC) >20%, greatest percentage of cancer (GPC) >50%, bilateral PCa, presence of cancer in both lateral portions, Gleason score >6.

Results

Only 32/102 (31.4%) specimens showed an organ-confined PCa; the remaining were pT3a in 30 (29.4%) cases, pT3b in 6 (5.9%) and pT2–T3 with positive surgical margins in 34 (33.3%). Quantitative histology predicted an organ-confined PCa in 41.2% of patients. In all 102 patients and in 56 with T1c clinical stage, the positive predictive value (PPV) and negative predictive value (NPV) of biopsy findings, to predict an organ confined PCa, was 81.2 vs 92% and 91.6 vs 93.4%, respectively. The PPV and NPV to predict a locally advanced PCa was 92.8 and 86.5%, respectively.

Conclusions

Quantitative histology seems to be helpful for locally staging of PCa in patients with T1c clinical stage and PSA ≤10 ng/mL.

Leiomyosarcoma of the bladder fourteen years after cyclophosphamide therapy for retinoblastoma

We report a case of bladder leiomyosarcoma which occurred in a 22-year-old female who had been treated with cyclophosphamide for a period of 68 months for retinoblastoma diagnosed at 18 months postpartum. Partial cystectomy was performed. Forty-two months after the operation she is tumor-free.

High plasma insulin and lipids profile in older individuals: the Italian longitudinal study on aging

BACKGROUND

The inverse relationship of insulin level to high-density lipoprotein (HDL)-cholesterol and its positive association with hypertriglyceridemia has been demonstrated in several studies; however, the relationship of insulin to low-density lipoprotein (LDL)-cholesterol in elderly persons is not clear. This study investigates the relationships of fasting plasma insulin and selected metabolic and biological risk factors in an aged population.

METHODS

The present study is based on a cross-sectional analysis of the data collected at baseline of the Italian Longitudinal Study on Aging in 1992 on a random sample of 5632 Italians aged 65-84 years. Analyses were performed to compare the distribution of risk factors, such as blood level of lipids, creatinine, albumin, fibrinogen, apolipoprotein A-1 and B, blood pressure, and body mass index (BMI), by quartiles of insulin, in both diabetic and nondiabetic participants.

RESULTS

Significantly higher levels of triglycerides and BMI and lower levels of HDL-cholesterol were found in the upper quartile of insulin among nondiabetic individuals. In men, we also found significantly higher levels of systolic and diastolic blood pressure. The same trend for these variables, although not significant for HDL-cholesterol and blood pressure, was seen in diabetic men. In diabetic women, total and LDL-cholesterol were significantly lower in the highest insulin quartile (p <.001), while no significant differences were seen in nondiabetic women or in men. We also found higher levels of white blood cells in the highest insulin quartile of diabetic women.

CONCLUSIONS

These results, apparently in disagreement with earlier reports on the clustering of cardiovascular disease risk factors in hyperinsulinemic individuals, could be due to the high frequency of chronic inflammation and the high prevalence of urinary infections in older diabetic women.

Atherosclerosis and pancreatic damage

The appearance of diabetes in advanced age may be considered as a part of the involutive processes of aging, and as such, it might have a pathogenesis completely different from that of type 2 diabetes of medium age. As a matter of fact, it has been observed that the pancreas undergoes numerous structural and functional alterations with advancing age, both in exocrine and endocrine parts. The present studies have been performed to reveal the quantity and quality of the pancreatic lesions, which may be attributed to atherosclerosis. We have already studied elderly subjects, therefore, we were now looking for further supports in a population of middle age people, died in complications of malignant hypertension. We investigated the pancreas, kidney and heart of 36 subjects (20 males and 16 females) with mean age of 48.6+/-8.9 years. Of this group, eight subjects (22.2%) became diabetic after the appearance of malignant hypertension. Arteriolar atherosclerosis damage (hyalinosis, thickening and stenosis) of the pancreatic arterioles were found in 92.8% of the non-diabetic, and in 87.5% of the diabetic subjects. Lesions of the pancreatic islets were observed in 32% of the non-diabetics, and in 50% of the diabetic subjects. The pancreas is an organ, which tends particularly to develop atherosclerotic damage. The vascular lesion of atherosclerotic origin, independently from the mechanism of its appearance, causes first only a decrease of the blood flux and hypoxia in the pancreatic islets with a consecutive functional decline of the beta-cells. This is then followed by structural modifications of the islets accompanied by the appearance of hyalinosis, loss of beta-cells, and a further decrease of insulin production.

Do men and women follow different trajectories to reach extreme longevity? Italian Multicenter Study on Centenarians (IMUSCE)

Gender accounts for important differences in the incidence and prevalence of a variety of age-related diseases. Considering people of far advanced age, demographic data document a clear-cut prevalence of females compared to males, suggesting that sex-specific mortality rates follow different trajectories during aging. In the present investigation, we report data from a nationwide study on Italian centenarians (a total of 1162 subjects), and from two studies on centenarians living in two distinct zones of Italy, i.e., the island of Sardinia (a total of 222 subjects) and the Mantova province (Northern Italy) (a total of 43 subjects). The female/male ratio was about 2:1 in Sardinia, 4:1 in the whole of Italy, and about 7:1 in the Mantova province. Thus, a complex interaction of environmental, historical and genetic factors, differently characterizing the various parts of Italy, likely plays an important role in determining the gender-specific probability of achieving longevity. Gender differences in the health status of centenarians are also reported, and an innovative score method to classify long-lived people in different health categories, according to clinical and functional parameters, is proposed. Our data indicate that not only is this selected group of people, as a whole, highly heterogeneous, but also that a marked gender difference exists, since male centenarians are less heterogeneous and more healthy than female centenarians. Immunological factors regarding the age-related increase in pro-inflammatory status, and the frequency of HLA ancestral haplotypes also show gender differences that likely contribute to the different strategies that men and women seem to follow to achieve longevity. Concerning the different impact of genetic factors on the probability of reaching the extreme limits of the human life-span, emerging evidence (regarding mtDNA haplogroups, Thyrosine Hydroxilase, and IL-6 genes) suggests that female longevity is less dependent on genetics than male longevity, and that female centenarians likely exploited a healthier life-style and more favorable environmental conditions, owing to gender-specific cultural and anthropological characteristics of the Italian society in the last 100 years.

Increased sleeping time after pentobarbital anesthesia in rats treated with intravenous injection of BCG

Intravenous injection of BCG in rats induces protection against liver cell necrosis produced by CCl4. Impairment of hepatic mixed function oxidases by cytokines produced by activated Kupffer cells is the mechanism proposed to explain that protection. To verify the function of hepatic mixed function oxidases after Kupffer activation, the sleeping time after sodium pentobarbital anesthesia was evaluated in rats after intravenous injection of BCG. Male adult albino rats received BCG (50 micrograms, intravenous) and 48 h or 6 days after were anestethized with sodium pentobarbital (33 or 66 mg/g i.p.). The sleeping time was measured from the beginning of sleep until the animal started having spontaneous movement and stand up on the forepaws. The results showed that the animals treated with BCG presented a significative increase in the sleeping time, indicating reduced inactivation of the pentobarbital, an indirect evidence of inhibition of mixed function oxidase system. BCG treated rats showed hepatic and splenomegaly, both 48 and 6 days after treatment. Histology showed an increase in number of mononuclear cells in the sinusoids in the liver and in the red pulp of the spleen 48 h after injection. Small epitheliod granulomas scattered in the hepatic lobules and in the red pulp were observed in rats killed six days after the BCG injection. Hepatocyte injury, induced by activated macrophages, would be not responsible for the reduced pentobarbital inactivation, because at six days there were several granulomas scattered in lobules, but the increase of sleep time in this group was similar to that observed in rats 48 h after injection of BCG. These results demonstrate that activation of Kupffer cells with BCG induces impairment of mixed function oxidase system soon as 48 h after injection of activator, probably due to production of IL-1, IL-6 and TNF alpha by activated Kupffer cells and other mononuclear cells migrated to the liver.

La terapia chirurgica tradizionale della fibrosi retroperitoneale idiopatica: Traditional surgical treatment of idiopathic retroperitoneal fibrosis

Surgical treatment of idiopathic retroperitoneal fibrosis is indicated in the most advanced stages of the disease and aims at resolving the urinary obstruction by freeing the ureters of the compressing and enveloping fibrous plaque. The purpose of this study was to briefly review the traditional surgical techniques, while assessing the results of the main reports in literature.

Kupffer cell activation with BCG. Corynebacterium parvum or zymosan protects against acute liver injury induced by carbon tetrachloride in rats

Kupffer cells have been implicated in the pathogenesis of liver injury, but there is controversy about the effects of activation of these cells on the hepatotoxicity of chemicals and endotoxin. It has been shown that injection of Corynebacterium parvum in rats induces macrophage activation that protects against toxic effects of carbon tetrachloride and acetaminophen, five days after injection, and this protection is due to inhibition of microsomal oxidizing enzymes and increased production of glutathion. To verify if the protective effect occurs soon after Kupffer cell activation, with different activators, male albino rats were treated with intravenous injection of BCG (0.5 ml with 7.5.10(8) bacilli), Corynebacterium parvum (30 mg/kg) or zymosan (7.5.10(6) yeast cells). Fourty-eight hours after the injection of one of the macrophage activators, the animals and rats treated with intravenous injection of saline (controls) received carbon tetrachloride by subcutaneous route (1 ml/kg of CCl4, 3:1 in soybean oil). Fourty-eight hours after the animals were killed after ether anesthesia and fragments of the liver were fixed, paraffin embedded and the sections stained with hematoxylin and eosin. A Weibel grid with 168 points was used to estimate the percent volume of necrosis and severe hydropic degeneration. The results showed that the volume density of necrosis and severe hydropic degeneration were significatively lesser in rats treated with the three Kupffer cells activators. The protection was greater with BCG and Corynebacterium parvum than with zymosan. These results confirm that activation of Kupffer cell with three different activators can induce protection against liver cell injury produced by carbon tetrachloride in rats soon as 48 h after injection of activators.

[Leydig cell tumor of the testis]

It represents a rare and mostly unilateral pathology with benign istological patterns. However, since the biological behaviour of the tumor is not foreseable from the istological characteristics, the follow-up must be prolonged. The treatment of this cancer is orchidofuniculectomy, sometimes associated, in selected cases, with retroperitoneal lymphadenectomy. In presence of tumor of small dimensions, above all if bilateral ones, it may be indicated a conservative treatment. Authors report six cases of Leydig cell tumors of the testis observed in sixteen years. All patients had orchidofuniculectomy by inguinal approach. In only one case has been associated retroperitoneal lymphadenectomy for the suspect of lymphatic metastasis. Follow-up of 3 months to 15 years is available for all patients: no one has died for the tumor and all are without signs of disease.

Analysis of cell growth with biparametrical flow cytometry in bladder cancer as prognostic evaluation

The aim of this work is to compare a biparametrical analysis of DNA using flow cytometry with the monoparametric approach. We analysed 71 samples coming from neoplastic tissue and from non-neoplastic tissue. We compared the average uptake of BrdU (22.37%) with the traditional prognostic parameters. Even if in some cases we found a certain correlation between the traditional prognostic parameters and the average uptake of BrdU, the results are still not encouraging. A final answer can only be supplied after analysing a greater number of cases and after a suitable follow-up period.

Mini-invasive surgery of renal cysts: Economic evaluation

The aim of this work is to compare the cost and the financing connected with percutaneous alcoholisation and aspiration, percutaneous resection and laparoscopic treatment of renal cysts. All the techniques in question present an advantageous cost-financing ratio and are typical procedures which can be employed in “one-day surgery”.

Acute scrotum: Analysis on 333 cases

Treatment of acute scrotum is becoming increasingly more common in urological surgery. The aim of this work was to analyse all the cases of acute scrotum subjected to surgical exploration in the last 20 years. Funicular torsion was found in 51% of patients, appendicular testis torsion in 26%, alterations compatible with previous funicular torsion in 15%, while findings were negative in 7%. Surgery to relieve funicular torsion and eversion of the vaginal was performed in 82% of cases, while the testis was fixed in 12% and in 11 cases orchiectomy was necessary. The contralateral testis was never fixed. No recurrence of funicular torsion has been found during follow-up, but in 9% of patients contralateral funicular torsion occurred at a later date.

[Centenarians: health status and life conditions]

The progressive lengthening of the average life span and the expanding elderly population high-light the phenomenon of "centenarianism" or extreme longevity in Italy. A large number of Italian Geriatric and Gerontology Centers throughout Italy have joined in the Italian Multicenter Study on Centenarians which evaluates the clinical and biological conditions of centenarians. A census of centenarians in Italy as of December 31, 1993 is presently in course. Preliminary data indicate that about 6000 subjects were alive on that day. Interesting epidemiological and biological information is also being processed. Scores based on the mini mental state, the index of independence in activities of daily living, the instrumental activities of daily living, and the geriatric depression scale, as well as laboratory tests, and case histories have evidenced a number of particular characteristics of centenarians: their longevity is familiar; centenarians live in a familiar and comfortable environment; they have been hard workers, and they have a good degree of mental self-sufficiency; they have never presented the classic risk factors, have always followed a balanced diet based on natural foods; they maintain a well-conserved immune system and especially natural killer activity; they have a normal lipidic balance and no symptomatic hyperglycemia. Mobility and morbidity rates are high. Further studies and interdisciplinary research should enable us to gain better understanding of the aging process and of life "over 100".

Vesicovaginal fistulas: our experience and review of literature

Vesicovaginal fistulas (VVF) still represent a sad complication of surgery of the female genital system. In this article an extensive review of the literature was conducted, analyzing the etiological, pathological and clinical aspects, as well as the therapeutical problems. For this purpose, we have compared the many surgical techniques proposed for treatment of VVF and have also evaluated their results. Furthermore, we report on our series of 35 patients who had undergone treatment for VVF.

Ipriflavone-treatment of senile osteoporosis: results of a multicenter, double-blind clinical trial of 2 years

Eighty-four out of 100 enrolled female patients affected by osteoporosis completed a double-blind, randomized trial, using ipriflavone (IP) in a dose of 3 x 200 mg/day (41 patients) or placebo (P)(43 patients). All patients received 1 g/day oral calcium supplementation. Inclusion criteria were: age over 65 years; at least one vertebral fracture in the past; bone mineral density measured at the distal tenth of the radius lower than the normal average -2 x S.D. The trial period was between June 1990 and November 1993. Patients of the IP group showed a significant increase in bone mineral density (P < 0.05) compared with the starting values during the whole study period. Pain decreased rapidly, intake of analgesics dropped, and often significant decreases in calciuria, hydroxyprolinuria, alkaline phospatase, osteocalcin and parathormone values were observed. Only two new fractures occurred during the trial in the IP group. Patients of the P group at the end of the study displayed decreased bone mineral densities (P < 0.05), increased pain, greater consumption of analgesics, and often significant increases in the bone metabolism parameters listed for the IP group. In the

Expression of ornithine decarboxylase gene in elderly human monocytes

The proliferative capacity of the immune system is impaired in elderly subjects and the expression of various genes involved in cell cycle progression is reduced in PHA stimulated lymphocytes during the aging process. Macrophages play a fundamental role in the immune system response. It has recently been demonstrated that the process of macrophage activation is accompanied by a rapid, transient rise of ornithine decarboxylase (ODC) mRNA levels. In fact, the ODC gene seems to be involved in macrophage activation and differentiation. The authors demonstrated that the steady-state levels of ODC mRNA and the correlated superoxide anion production are lower in the monocytes of elderly subjects with respect to those in young subjects used as control. These results confirmed the impaired immune function of the elderly.

Management of the urological Day Hospital

Day Hospital treatment offers the patient a wide range of services. The number of patients who take advantage of this structure is growing every day and this fact creates some problems in the management of such a service. For this reason we have created a computerised programme which has made the management of the Day Hospital service easier and allows us to carry out research and analyses on the activities done.

[The complications of lumbotomies]

After having described the surgical anatomy of the lumbar region, with particular regard to the relationships with pleura and peritoneum, as well as to the course of the nervous structures of the region (12th intercostal, ileohypogastric and ileoinguinal), the authors describe the possible complications related with the surgical approaches to the lumbar region. Pathogenesis of post-operatory pains and parietal hypotonies is especially evaluated; these complications may be caused by section, ligature or compression of one or more nervous trunks. The authors conclude that the respect of the anatomic structures located in the lumbar region represents the best way in order to prevent most complications related to lumbotomies.
