[Influence of diet on lipoprotein profile in familial combined hyperlipidemia affected children].

BACKGROUND: Familial Combined Hyperlipidemia is an inherited disorder affecting cholesterol and triglycerides metabolism, well known myocardial infarction risk factors. The FCHL clinical presentation is usually silent until the third decade although children can be affected, and the more recent opinion is that precocious diagnosis is mandatory in preventing complications. Aim of this study is to examine the effectiveness of the diet therapy (Step-One-Diet) in a group of 13 children affected by Familial Combined Hyperlipidemia. METHODS: The patients have been submitted to a normocaloric diet, 30% fat of the total caloric daily intake according with the Dietary Intervention Study in Children (Step-One-Diet). The patients then have been submitted to a two year-follow-up and lipoprotein levels (total cholesterol, LDL-cholesterol, triglycerides and apolipoprotein B), nutritional status (macro- and micro-nutrients) as well as anthropometric data (height, weight, BMI) have been monitored. RESULTS: Results showed a 10% total cholesterol and 30% triglycerides decrease, Iron and Calcium intake show increased levels approaching to the normal ones after controlled diet, while cholesterol intake was correct on both regimen. The growth parameters show a decrease in weight only in two obese and two overweight patients. CONCLUSIONS: The present study confirmed the effectiveness and safety of the Step-One-Diet in children patients, allowing triglycerides normalization in 60% of the patients, and a 10% cholesterol decrease, in agreement with the complex genetic inheritance of the disease.

Effect of enzyme inducing anticonvulsants on ethosuximide pharmacokinetics in epileptic patients.

1. To assess the effect of enzyme inducing anticonvulsants on ethosuximide pharmacokinetics, plasma ethosuximide concentrations after a single oral dose (500 mg) of the drug were compared in 12 healthy control subjects and 10 epileptic patients receiving chronic therapy with phenobarbitone, phenytoin and/or carbamazepine. 2. Compared with controls, epileptic patients showed markedly shorter ethosuximide half-lives (29.0 +/- 7.8 vs 53.7 +/- 14.3 h, means +/- s.d., P < 0.001) and higher apparent oral clearance (CL/F) values (15.3 +/- 3.8 vs 9.2 +/- 1.9 ml kg-1 h-1, P < 0.001). The apparent volume of distribution (V/F) of ethosuximide was slightly lower in the patients than in controls (0.6 +/- 0.1 vs 0.7 +/- 0.1 l kg-1, P < 0.05). 3. These findings provide evidence that ethosuximide elimination is increased by enzyme inducing anticonvulsants, the effect probably being mediated by stimulation of cytochrome CYP3A activity. 4. The enhancement of ethosuximide clearance in patients comedicated with enzyme inducing anticonvulsants is likely to be clinically relevant. Higher ethosuximide dosages will be required to achieve therapeutic drug concentrations in these patients.

[Modified Gilbert's technique in the treatment of persistent inguino-scrotal hernias in aged patients].

In elderly males, and in particular in very old men, the anatomical changes produced by senility encourage the formation of large inguino-scrotal hernias. Their repair may be achieved using Gilbert's technique to which the authors have proposed a number of variants. The good results show that the "tension-free" technique may be correctly applied in elderly patients with inguino-scrotal hernias, thus allowing a straightforward postoperative recovery with no complications.

[A case of ureteral stenosis and ureterorectal fistula secondary to sigmoid diverticulitis].

The paper reports a case of ureteral [correction of urethral] stenosis with ureterorectal [correction of urethro-rectal] fistula due to diverticulitis of the sigmoid [correction of sigma] which resolved following reconstruction of the urinary tract by ureterocystostomy [correction of urethrocystotomy] using a modified version of Boari's technique, with satisfactory renal functional recovery. On the basis of an analysis of the literature, the authors comment on ureteral [correction of urethral] stenosis and its etiological diagnosis.

[A case report of Castleman's disease in a patient with endometrioid adenocarcinoma of the ovary].

The Authors report a case of Castleman's disease in a 45-year-old woman. She was admitted to hospital because of a thrombophlebitis of the left lower limb. An abdominal echotomography showed evidence of a mass with a diameter of about 6 cm at the pancreatic isthmus, and a cyst (diameter 25 mm) in the right ovary. An explorative laparotomy was performed and the masses were removed. Histological examination identified them respectively as a Castleman's disease of hyaline-vascular type and an endometrioid carcinoma of the ovary.

[Immunological variations after thymic stimulation with special reference to IL2-RS in patients operated for neoplasms].

The paper reports a study which was carried out to assess immunological function by assaying IL2 in cancer-operated patients treated with thymostimulin. The results of the study show that, used in normally fed, immunodepressed patients, this immunomodulator is able to normalise levels of lymphocyte subpopulations and to bring serum concentrations of IL2-RS to the levels of normoergic patients.

[Constipation: drug or surgical treatment?].

Constipation is a very frequent symptom. It affects 7-10% of people. Otherwise a severe constipation exists which is rare, but extremely serious with evacuations every 15 days to 2 months. We expose the classification of constipation in its types: colonic, rectal and anal. We analyse the diagnostic trial which has to be started with a careful anamnesis and well directed physical examination. Laboratory tests and instrumental investigations will be essential means to define exactly the type of constipation and its pathogenetic mechanism. We go deep into physical involvement of constipation and into the problem of constipation in the elderly: except for particular groups (women suffering from colonic hypokinetic constipation) the age of patient is usually old. Medical treatment is described especially regarding the type of constipation. At last we review the surgical techniques proposed for every form of constipation, with exposure and interpretation of their results.

[Economic amputations of the lower limbs due to ischemia. I].

The problem relating to leg amputation following ischemia are analysed in the first part of this study, bearing in mind that amputation must be as conservative as possible in order to ensure the best quality of life. Following a short review of the topic and the introduction of recent trends, the case for amputation, which must be early in order to be conservative, is studied. The first part of this article concludes with a discussion of Doppler and clinical evaluations as techniques used to determine the level of amputation.

[Economic amputations of the lower limbs due to ischemia. II].

In this second note, some technical details used during amputation are described, leaving out the systematic description of interventions. The analysis of the postoperative period shows that the more distal the amputation, the higher the incidence of local complication, while about postoperative mortality our data show an opposite trend. The Authors conclude by pointing out that an early indication and an accurate evaluation often allow a more distal amputation, that must be as conservative as possible anyway.

Biliary reflux after cholecystectomy: a prospective study.

The authors carried out a prospective study to ascertain whether cholecystectomy itself might be the cause of duodenogastric reflux. Patients with cholelithiasis were examined and underwent the following tests: hemanalysis, gastroscopy with biopsy, 24 hour pH-metry and acetaminophen test. Twelve patients were selected. Six months after the operation the tests were repeated. All patients were asymptomatic. Hemanalysis was normal in all 12 patients and no difference was seen in the tests of 5 of the patients; however in the other 7 differences were observed in all the tests. The authors conclude that cholecystectomy helps to provoke duodenogastric reflux in predisposed patients, and that this reflux may be asymptomatic.

[Relations between markers and immunological status in surgical patients. Tumor markers and immunity in surgery].

The correlation between the immunological status of surgical patients and cancer is examined. 52 patients with gastric and colonic cancer were studied. On the basis of the immunological results of skin tests these were subdivided into non-reactive and reactive. The two groups were statistically compared in relation to cancer stage and blood concentrations of 4 markers: CEA, Ca 19-9, Ca-50, T.A.T.I. The first data show that anergic patients are older to a statistically significant degree; the second that there are no significant differences between the two groups as regards cancer stage. The third data show a difference between the two groups in relation to two of the four markers; anergic patients have a statistically significant higher blood concentration of CEA and T.A.T.I. This is rather interesting, since the literature offers no specific studies on the correlation between the patient's immunological status and tumour marker concentration. Therefore, in clinical practice, the high concentrations of these markers, could reveal, as well as the presence of cancer an endangered immunologic status.

[External saphenous vein excision with mini-phlebectomy].

The surgical treatment of the varicosities of the short saphenous vein is one of most controversial matter of modern phlebology. The anatomy of this vessel, that is deep, and is accompanied by the sapheno external nerve, can be very varied species for that which concerns the sapheno popliteal joint. The traditional surgery as the sclerotherapy exposes the patient to risks and failures. For such reasons the authors believe that the modern technique of stab evulsion phlebectomy could be formatted like the treatment of choice of the venous pathology of the short saphenous vein. Synthesizing, the stab evulsion phlebectomy consists of the removal of the varicosities of the lower limbs through incisions of the skin of 1-3 mm using special surgical instruments with hook (Chrochets). The technique doesn't foresee neither stitching neither vascular binding, and could be performed on local anesthesia and in ambulatory regimen. The results of the technique and the absence of complications suggests its adoption of principle in the treatment of the incompetence of the short saphenous vein.

[Cholecystectomy by minilaparotomy].

The authors relate their experience of 62 cases of minicholecystectomy. This procedure is compared to "open" conventional and laparoscopic cholecystectomy. Report results and the analysis of the literature shows that the technique of cholecystectomy by minilaparotomy is a valid option to laparoscopic cholecystectomy and represents a clear improvement compared to conventional cholecystectomy.

[Fistulae in diverticular disease of the colon].

Fistulas in colon diverticular disease are a not uncommon complication, that arise spontaneously in the evolution of a diverticulitis, and also as a complicated dehiscence of surgical anastomosis. The intermediate step of a fistula is a deep abscess that finds through the parietal layers of abdomen or towards other adjacent organs. So the surgeon can be confronted with external and internal and complex fistulas. As for diagnostic manoeuvres, the surgical choices are outside a rigid schedule, and is on the personal sensibility of the surgeon.
