[Inguinal hernia surgery. Review of a caseload and description of a technique variation].

BACKGROUND: To evaluate the efficacy of the tension free surgical technique for the treatment inguinal hernia. METHODS: The authors propose personal experience of 172 patients, treated for inguinal hernia in the period from 1986 to 1993, selecting two patients groups. In the first group the patients (80 cases) were treated with traditional hernioplasty, in the second group (92 cases) hernioplasty tension-free was performed. RESULTS: In the first group 6 cases of recurrence (6.7%), have been observed and in the second group only one case. CONCLUSIONS: The results obtained, and literature survey show the advantages of hernioplasty tension-free.

Diagnosis controversies for adrenal ganglioneuroma.

The authors report a case of adrenal ganglioneuroma which was incidentally diagnosed performing preoperative examination for a sigmoid carcinoma. The authors took this finding as a starting point to underline the rarity of this condition and its chance discovery, this being due to the rare presence of signs and symptoms and its frequent association with other synchronous neoplasms; all this makes differential diagnosis rather difficult.

[The usefulness and limits of echo-endoscopy in the clinical staging of esophageal cancer].

Endoscopic ultrasonography (EUS) is a diagnostic method of considerable value for the local staging of esophageal cancer, in particular for T and N evaluation. After an extensive review of the literature, the authors underline the possibility of using EUS to improve the treatment and prognosis of esophageal neoplasms based on the use of various stage-dependent therapeutic strategies. EUS is regarded as a gold-standard technique for esophageal cancer staging in order to select appropriate treatment options, but is currently hampered by the intrinsic difficulty and subjectivity of interpreting ultrasonographic images. In order to ensure safe and reliable data, EUS must be carried out by operators who have undergone suitable training at a specialised centre.

Neuroendocrine tumors of the gastroenteric canal. Anatomopathological and diagnostic-therapeutic definition. Description of a case with a rare cecal localisation.

The authors take the case of a neuroendocrine tumour of the cecum as the starting point for an analysis of the anatomopathological and diagnostic-therapeutic aspects of these neoplasms. Furthermore, the authors underline that neuroendocrine tumours (NET) of the colon represent an extremely rare nosological entity and that they are heterogeneous from a clinical and biochemical point of view, thus making a reliable preoperative diagnosis a problem that is still difficult to resolve today.

Primary non-Hodgkin lymphoma of the parotid gland.

The rarity of primary non-Hodgkin lymphomas of the parotid gland triggers this report on a case treated and now in the fourth year of follow-up, which offers the opportunity for a review of the literature on the subject. The paper also describes the criteria for accurate classification, the diagnostic tools available and the problems of differential diagnosis. Treatment protocols and survival are also considered.

Pattern of cytokines and pharmacomodulation in sepsis induced by cecal ligation and puncture compared with that induced by endotoxin.

The production of tumor necrosis factor alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), and IL-6 and their pharmacomodulation were evaluated in a model of polymicrobial sepsis induced in mice by cecal ligation and puncture (CLP) and were compared with the effects of endotoxin (lipopolysaccharide [LPS]) treatment. LPS levels rose as early as 1 h after CLP and increased further after 2 and 21 h. TNF-alpha was detectable in serum, spleen, liver, and lungs during the first 4 h, with a peak 2 h after CLP. IL-1 beta was measurable in serum after 24 h, and levels increased significantly in spleen and liver 4 and 8 h after CLP. IL-6 levels increased significantly in serum throughout the first 16 h after CLP. These cytokines were detectable after LPS injection, with kinetics similar to those after CLP but at a significantly higher level. To cast more light on the differences between these two animal models of septic shock, we studied the effects of different reference drugs. Pretreatment with dexamethasone (DEX); ibuprofen (IBU), an inhibitor of cyclooxygenase; and NG-nitro-L-arginine, an inhibitor of nitric oxide synthase, significantly reduced survival, while chlorpromazine (CPZ) and TNF did not affect it. Only the antibiotics and pentoxifylline significantly increased survival in mice with CLP. However, CPZ and DEX protected the mice from LPS mortality. On inhibiting TNF-alpha with DEX, CPZ, or pentoxifylline, survival was reduced, unchanged, and increased, respectively, and on increasing TNF-alpha with IBU and TNF, survival was decreased or unchanged, respectively, suggesting that the modulation of this cytokine does not play a significant role in sepsis induced by CLP, unlike treatment with LPS. The negative effects of IBU and N(G)-nitro-L-arginine suggest a protective role by prostaglandins and nitric oxide in sepsis induced by CLP.

A comparison of the local tolerability, safety and efficacy of meloxicam and piroxicam suppositories in patients with osteoarthritis: a single-blind, randomized, multicentre study.

The local tolerability, safety and efficacy of meloxicam 15 mg suppositories were compared with piroxicam 20 mg suppositories over a 3-week period in a single-blind, randomized study in patients with osteoarthritis. Patients were randomized 2:1 to receive meloxicam (n = 216) or piroxicam (n = 109). More than 90% of patients and investigators assessed local tolerability of both treatments as good or very good (primary endpoint). There was no significant difference between the groups. Global efficacy was reported by approximately 80% of patients in both groups to be good or very good. Pain on movement and at rest and joint mobility showed statistically significant improvements compared with baseline with both meloxicam and piroxicam; there were no statistically significant differences between treatment groups. Piroxicam and meloxicam suppositories were equally well tolerated, with no serious adverse events recorded in either treatment group. Local adverse events occurred in 11.9% of patients receiving piroxicam and 6.9% of those receiving meloxicam. Overall, gastrointestinal adverse events were the most frequent of all 11.9% of piroxicam-treated patients). In both groups, about 90% of global tolerability assessments were classified, by the investigator and the patient, as either very good or good. In conclusion, meloxicam 15 mg suppositories showed excellent local tolerability accompanied by good safety and efficacy in osteoarthritis, which was comparable to that of an established non-steroidal anti-inflammatory drug (NSAID) administered by the rectal route, and to that previously observed with oral formulations of meloxicam 15 mg.

Long-term antimicrobial prophylaxis in lung cancer surgery: correlation between microbiological findings and empyema development.

This study was planned in order to determine the value of antimicrobial prophylaxis in preventing post-operative empyema in patients undergoing lung cancer surgery. Two-hundred consecutive subjects operated upon for lung cancer received teicoplanin and aztreonam, starting at the induction of anesthesia and lasting until removal of the pleural drains. Cultures for aerobic and anaerobic bacteria were taken from: (1) the bronchus at the time of surgical division; (2) the pleural space before closure of the chest; (3) the pleural fluid during the post-operative period; and (4) the tips of chest drains at the time of their removal. In the 200 patients receiving antibiotic prophylaxis, the number of post-operative empyemas (1%) was lower than that (7.5%) found in 53 comparable patients who were previously treated with placebo. In the 'placebo group', empyema was due to gram-positive bacteria, while in the 'prophylaxis group', it was caused by Gram-negative bacteria (Pseudomonas aeruginosa). A significant (P < 0.05) correlation between infected bronchial secretions, pleural space contamination at surgery, contamination of chest fluid and drains during the post-operative period, and empyema development was demonstrated. In conclusion, antibiotic prophylaxis, while being effective in preventing post-operative empyema, may induce the colonization of the respiratory tract with highly resistant gram-negative bacteria.

[Not Available].

Lots of theories about generation up to the XXVII century base themselves on the marvelous power of parents' imagination - the mother's above all - of conveying resemblance to the foetus or conditioning its shape till to the extreme monstruosity. For a long time mother's fancies explain the appearance of naevus, cravings, skin spots, hair colour, congenital deformities and so on. We can recognize one of the grounds of that idea, perhaps the most authoritative, in a biblical passage having Jacob the Patriarch as protagonist. This essay deals with history of the imaginationist theory from Jacob's episode and its following interpretation, with a particular attention for its influence on eugenic doctrines in fashion during the centuries XVI and XVII.

[Surgical treatment of non-toxic multinodular goitre. Retrospective evaluation of a personal case series].

The authors base their study on a retrospective evaluation of a personal series of patients and on a review of the literature on this topic. They focus their attention on surgical problems relating to the type of treatment of non-toxic multinodular goitre. On the basis of the data obtained, they underline that in this pathology total thyroidectomy is the most appropriate form of surgery and does not entail a higher morbidity in relation to more conservative resection.

Pharmacokinetic studies of diosmin and diosmetin in perfused rat liver.

1. The kinetics and metabolism of diosmin and diosmetin were investigated in the isolated perfused rat liver in order to assess the role of the liver. 2. Diosmetin and especially diosmin disappeared quickly from the perfusion medium. 3. Both flavonoids were rapidly metabolized and diosmetin was partly excreted in bile as the glucuronide and sulphate and diosmin was partly excreted in bile as such and as the glucuronide conjugate. 4. Diosmin and diosmetin did not appear to affect various parameters of liver function.

[Diacereine: an original approach in the treatment of degenerative and/or extra-articular rheumatism].

71 patients with variously located osteoarthrosis or primary fibromyalgic syndrome were treated with oral diacereine (DAR). The case series was accumulated in successive periods and may be divided into three groups. An "open" test on DAR (100 mg/die for 4 weeks) was conducted on the first group of 31 arthrosis patients. On the second group of 20 other arthrosis patients a "double-blind, cross-over" test was carried out using DAR (100 mg/die) and naproxene (500 mg/die) both for 2 weeks. The third group of 20 patients with fibromyalgia was treated with DAR alone: 100 mg/die 5 days a week for 12 weeks. The efficacy of the treatment was judged on the basis of the following parameters: rest pain, pressure pain, pain on active and passive movement, and functional limitation. In the first group a positive therapeutic effect was noted in 20 cases (68.9%). There were side effects (moderate diarrhea) in 3 patients 2 of whom suspended treatment. In the second group, DAR and naproxene had an almost identical effect. However 7 patients (36.8%) expressed a preference for DAR, 9 (47.4%) expressed no preference and only 3 (15.8%) preferred naproxene. Side effects were encountered in 3 patients treated with naproxene (2 cases of epigastralgia and pyrosis and 1 case of dyspnea so marked as to require suspension of treatment) and in 3 treated with DAR (modest diarrhea). In the third group, a positive therapeutic effect was noted in 68.4% of the patients with fibromyalgia with a 15% incidence of side effects consisting of slight abdominal pain (diarrhea caused suspension of treatment in 1 case only). Blood chemical parameters were studied in all three groups and no alterations attributable to the treatment were found. The obtained result suggests that the new drug is effective and well tolerated in the envisaged indications.

Effects of suprofen on renal function in patients with rheumatoid arthritis.

Suprofen is a new potent analgesic with antiinflammatory properties that appears to inhibit prostaglandin synthetase in a tissue-selective manner, having relatively little effect on the kidneys of experimental animals. The effects were studied of one week of treatment of rheumatoid arthritis patients with suprofen or ibuprofen on Na+ and K+ excretion, creatinine clearance, urinary enzymes that are markers for tubular damage, and urinary prostaglandins such as PGE2 and 6-keto PGF1 alpha (a stable metabolite of prostacyclin). Neither compound caused changes in renal function related to the week of treatment, but significant decreases in prostaglandins were observed: this change was fully reversible after discontinuation of the drug.
