Allergic contact dermatitis to fragrances: part 2.

Allergic contact dermatitis due to fragrances usually manifests as subacute or chronic dermatitis because fragrances are found in a wide range of products to which patients are repeatedly exposed. The typical patient is a middle-aged woman with dermatitis on her hands and face, although other sites may be affected depending on the allergen and the product in which it is found. The standard patch test series of the Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC) contains 4 fragrance markers: balsam of Peru, fragrance mix i, fragrance mix ii, and lyral. Testing with a specific fragrance series is recommended in patients with a positive result to any of these 4 markers. The use of a specific fragrance series and new legislation obliging manufacturers to specify the fragrances used in their products, will help to improve the management of allergic contact dermatitis due to fragrances.

Allergic contact dermatitis to fragrances. Part 1.

Fragrances are a large group of substances and the second most common cause of allergic contact dermatitis in Spain. These potential allergens are extremely common and the general population is subject to continuous exposure on a daily basis. While the fragrance markers included in the current Spanish standard patch test series are good, there is room for improvement. New markers that have emerged in recent years have proven to be of value in standard series used in other countries. Diagnosing fragrance allergy has taken on even greater importance since the European Union added 26 fragrances to its list of mandatory ingredients to be specified on product labels. The aim of this review is to provide an update on allergic contact dermatitis to fragrances. We examine the main sources of exposure and clinical manifestations of this condition and propose a diagnostic and treatment protocol.

Motor responses of the esophagus and lower esophageal sphincter (LES) to vestibular stimulation in man.

Pressure recordings in the esophageal body, LES and stomach were performed in 10 healthy subjects before and after caloric stimulation of the labyrinth. While esophageal and stomach responses varied or were absent, all subjects showed variations at the LES level. Duration of LES relaxation was increased and both time and amplitude of LES augmentation were significantly reduced. The physiological mechanism of labyrinthine-digestive connections and the possibility of clinical applications are discussed.

[Thyroid metastasis of carcinoma of the breast. Considerations on 2 cases]. / Metastasi tiroidee da carcinoma della mammella. Considerazioni su due casi.

Two cases of thyroid metastasis from breast cancer are reported, both occurring in patients previously given radical mastectomies. It is emphasised that postoperative follow-up should also monitor rarely affected sites of metastasis from breast cancer.

[Indications, techniques, complications and results of sleeve lobectomy]. / Indicazioni, tecniche, complicanze e risultati della sleeve lobectomy.

AIM: The authors analyse their personal series and compare it with reported data in order to assess the functional results sleeve lobectomy offers with respect to traditional techniques. METHODS: Sixty-six sleeve lobectomies were carried out from 1986 to 2000. In 49 cases the operation was carried out on the basis of criteria of choice and in 17 of functional necessity. Three vascular sleeves and 5 tangential vascular plastic operations were associated. The disparity of lumen was corrected with oblique sections on the intermediate bronchus according to Merendino. In the case of reimplantation of the intermediate on the left main bronchus high frequency jet ventilation was necessary. The anatomoses were covered with broad pedunculated pleural strips. In 3 cases extramucosal myectomy of the medio-thoracic esophagus was carried out associated in 1 case with mucous resection and subsequent direct suture. RESULTS: Morbility was 34.5% (21% atrial fibrillation, 7.5% parenchymal complications, 4.5% anastomotic complications and 1.5% mediastinitis). Mortality at 30 days was 6% (massive hemoptysis in 3 cases and respiratory failure in 1 case). The pTNM of the 57 survivors was IB in 35 cases, IIB in 6 and IIIA in 16. Follow-up showed 5-year survival of 62% for stage IB and 24% for stage IIIA. CONCLUSIONS: On the basis of their experience, with a postoperative mortality and a rate of complications comparable to literature data, the authors consider that sleeve lobectomy, although it presents postoperative problems requiring more prolonged clinical control, is preferable to traditional operations because of the functional advantages it offers patients with lung cancer.

[Crossectomy combined with sclerosis in the ambulatory treatment of varicose veins]. / Crossectomia associata a sclerosi nel trattamento ambulatoriale delle varici.

This paper focuses on the advantages of an outpatient technique in the treatment of the 1st various syndrome based on crossectomy and complementary sclerotherapy to eliminate the proximal reflux. In addition to the speed, low costs and total absence of discomfort for the patient, this method results in a low percentage of easily correctable failures provided the patients to be treated are carefully chosen. Selection involves a preoperative screening phase based on anamnesis, semeiological tests, Doppler and evaluation of tibial venous pressure, as well as careful topographical mapping of proximal refluxes which allow a correct postoperative follow-up in the event of possible recidivation (14.3% based on the authors' experience). The surgical technique used entails an accurate crossectomy with full exposure of the SF crosse (??) and its affluent branches, and subsequent sclerotherapy with atoxysclerol in a variable quantity and % as required. Of a total of 91 cases treated with a 3-year follow-up, 5 cases of recidivation were observed during the first year and 8 during the third. In both cases postoperative pressure values in the tibial veins were considerably higher than in other patients and recidivation occurred through perforating sclerosed recanalised vessels.

[Vascularization of the gastric stump tubule in esophagogastroplasty (EGP)]. / La vascolarizzazione del tubulo gastrico nell'esofagogastroplastica (EGP).

The authors present the results of the vascular supply of tubulized gastric stump in patients who had sub-total oesophagectomy and cervical oesophago-gastroplasty (OGP) for oesophageal carcinoma, evaluating the importance of altered tubulized gastric stump's vascular supply on oesophago-gastric anastomosis efficiency. From April 1989 up today 51 patients who had OGP entered this study. Among these 2 had intestinal reconstruction by whole stomach and 49 by tubulized gastric stump. These 49 patients had celiac and upper mesenteric arterial angiography 30 days after surgery. As regards vascular patency angiography allowed us to divide the tubulized gastric stump into three parts; giving useful information above all on the distal part of the stump, considered "at risk" as concerning vascular supply. The authors thus demonstrate that the anastomosis high rate dehiscence is preferably due to the oesophageal stump vascular supply (strongly affected by cervical dissection) rather than to the poor vascular supply of the distal third of the transposed tubulized gastric stump.

[Arterio-portal fistula. Report of a case and review of the literature]. / Fistole artero-portali. Segnalazione di un caso e revisione della letteratura.

Mesenteric arteriovenous fistulas or arterioportal fistulas (APF) are rare and mostly secondary to penetrating abdominal wounds. A rare case of APF presenting 2 years later a blunt abdominal trauma has been reported. On the basis of a review of the literature (65 cases) the etiology, clinical findings, diagnostical aspects and the results of conservative and surgical treatment have been analyzed.

[Medullary carcinoma of the breast. A review of the literature and a report of the authors' own cases]. / Carcinoma midollare della mammella. Revisione della letteratura e presentazione della casistica personale.

Experience with 5 cases of medullary carcinoma of the breast is reported. Reviewing the literature, medullary carcinoma appears to have a better prognosis than infiltrating ductal carcinoma so the proper surgical approach is represented by conservative procedures for lesions < 3 cm with no more than 3 nodes involved. Chemotherapy and radiotherapy don't seem to improve the survival rate.

[Laparoscopic versus laparotomic adrenalectomy: preliminary experiences]. / Surrenectomia laparoscopica versus laparotomica. Esperienze preliminari.

The authors report their experience about laparoscopic surgery in the treatment of adrenal tumours. Three laparoscopic right adrenalectomies were performed. From a comparison with five open adrenalectomies, microinvasive surgery is more advantageous than traditional management: recovery is earlier, incisions are smaller, post-operative discomfort is less, physiologic functions recover in a short time, return to full professional activity in one week.

[Surgical treatment of liver metastases of breast carcinoma. Our experience]. / Trattamento chirurgico delle metastasi epatiche da carcinoma mammario. Nostra esperienza.

The authors report their experience in the surgical treatment of breast cancer liver metastases. Although with a restricted number of cases (4 patients), the short-term results are satisfactory; this is in agreement with the literature. The survival of those patients treated with a loco-regional approach to metastases (chemotherapy and surgery), is longer than one obtained using systemic chemotherapy. This is still an open question requiring further experience.

[Hemoperitoneum caused by lesions to the appendix epiploica. An unusual complication of colonoscopy]. / Emoperitoneo da lacerazione di appendice epiploica. Una rara complicanza della colonscopia.

A rare case of hemoperitoneum in a young man who performed a diagnostic colonoscopy is reported. The rupture of an epiploic appendix among rectum and colon sigma caused massive bleeding into the peritoneum cavity followed by haemorrhagic shock. Diagnostic and therapeutic colonoscopy has a low rate of morbility; perforation and bleeding are the most common events; hemoperitoneum following colonscopy is usually due to spleen rupture. Among other complications, ileal and cecal volvolus, incarceration of hernias and subcutaneous emphysema are reported.

[Proximal selective vagotomy in treatment of duodenal ulcer (author's transl)]. / La vagotomia selettiva prossimale nel trattamento dell'ulcera duodenale.

Thirty duodenal ulcer patients were subjected to proximal selective vagotomy (p.s.v.) and modified Dor antireflux plastic surgery. Accurate clinical, radiological, endoscopic, gastrosecretory, radioimmunological and PH-manometric tests were made before and 7 and 30 days after surgery. The results confirm the effectiveness of p.s.v. in treatment of ulcerous disease, and the usefulness of combining modified Dor plastic surgery in order to prevent postoperative feedback.

[Intraoperative evaluation of the high pressure zone in anti-reflux plastic operations]. / Valutazione intraoperatoria della H.P.Z. nelle plastiche antireflusso.

It has been done a manometric intraoperating study on 18 patients (7 acalasical megaoesophagi, 6 herniae of hiatus, 5 duodenal ulcers) who had undergone an operation of modified Dor's anti-reflux plastics. After Haller H.P.Z. pressure has gone down of 13 mmHg, and has gone up again of 5,5 mmHg after modified Dor; after plastics H.P.Z. average intraoperating pressure has been of 18 mmHg. The posterior plastics of hiatus and the reconstruction of His' angle for hernia of hiatus modify scarcely H.P.Z. pressure. During a superselective vagotomy we have recorded a modest reduction of H.P.Z. pressure, of which average intraoperating values after vagotomy and anti-reflux plastics have been of 16,5 mmHg. At a distance of 30 months from the operation it has been done a follow up on 70% of patients that had undergone an operation of anti-reflux plastics and also 18 patients that had had en intraoperating inspection. However it has been, a degradation of manometric values, the results have been satisfactory over 90% of cases. The authors insist on the utility of intraoperating manometry for a valuation of the completenes and the efficacy of the operation.

[The role of the Billroth I operation peptic ulcer surgery]. / Il ruolo della Billroth-I nella chirurgia dell'ulcera peptica.

The conviction is expressed that none of the operations today available for treatment of peptic ulcer is always effective for all types of patient; the surgeon must in fact be able to select and perform the operation most suitable for each case. In this connection the advantages and disadvantages of gastric resection according to Billroth's first method are considered. The fundamental stages of this operation are described in detail, with a critical analysis of the various pathological conditions in which its performance is indicated or, on the contrary, there is a precise contraindication. On the basis of the main parameters of judgment (follow-up, operating mortality, relapse rate, dumping syndromes and Visick's scale) obtained from personal experience and wide research on literature, a comparative evaluation is then made between Billroth I and other operations commonly used in treatment of gastroduodenal ulcer. In conclusion it is asserted that Billroth I is a technically good, physiological operation capable of ensuring immediate and long-term results not inferior to those of Billroth II and other operations; it therefore deserves to be considered among the methods of choice and more widely used.

[The interposed jejunal loop after resection for gastric ulcer (endoscopic study)]. / L'ansa digiunale interposta dopo resezione per ulcera gastrica (studio endoscopico).

Authors refer about an endoscopic study concerning twenty patients who have been previously operated for gastric ulcer. In these patients it was performed a reconstruction of the alimentary canal by means of a gastro-duodenal interposition of an isoperistaltic jejunal loop. Authors show that this method has been proved valid to prevent duodeno pancreatic reflux in the residual gastric sac.

[Raynaud's phenomenon: diagnostic and therapeutic aspects]. / Il fenomeno di Raynaud: aspetti diagnostico-terapeutici.

The Authors report their experience concerning 120 patients with Raynaud's Disease (50 pats.) or Syndrome (70 pats.). All patients were studied before and after treatment, by clinical, thermometric, oscillographic and photoplethysmographic observation and by the Doppler examination, in order to evaluate the functional and organic component of the disease. Surgical treatment was reserved to 45 patients with secondary or primitive Raynaud's phenomenon refractory to medical therapy. The treatment of choice was thoracic sympathectomy. The result was excellent in 64% of cases, fair in 26%, and nil in 8%. 75 patients were treated with various drugs for a period of 6 months or 1 year. In 54% of cases the result was excellent, fair in 29%, and nil in 16%. The Authors conclude that diagnosis of Raynaud's Syndrome is above all clinical, that a leading part is played by photoplethysmography and the Doppler examination, and that medical therapy is indicated in the first instance, since it is capable of preventing the rise of those distal trophic disorders that constitute one of the main indications of surgical treatment.

[Ultrasonography-guided percutaneous needle biopsy with large needle versus surgical biopsy in the diagnosis of breast lesions]. / Agobiopsia percutanea ecoguidata con ago grosso vs biopsia chirurgica nella diagnosi delle lesioni mammarie.

The authors report their experience on percutaneous large core biopsy with standard needle in the diagnosis of breast lesions. This method, that has the same advantages of open biopsy, allows a better cytological examination, prevent sequelae of surgery and lower costs.
