ABSTRACT

AIM: Elimination of the offending food is imperative in the management of children with cow-milk allergy/intolerance (CMA/CMI). Herein we report the result of randomized clinical trial carried out to test the efficacy and safety of a new almond-based food (hereinafter named almond milk) in a group of infant with CMI/CMA. METHODS: A group of 52 infants aged 5 to 9 months and with documented CMI/CMA was enrolled and randomized to: almond milk (Group A, n=26); soy-based formula (Group B, n=13); protein hydrolysate-based formula (n=13). The main efficacy outcomes were the improvement in clinical symptoms and the decrease in serum levels of soluble CD30 (a potential marker for atopic disorders; sCD30). RESULTS: Elimination of the offending food and supplementation with a milk protein-free formula produced a considerable improvement of clinical manifestations within 5-12 days in all cases examined (at the onset of the study: 26.4+/-5.4 U/mL and 7.9+/-5.2 U/mL in IgE+ and IgE- infants respectively, after 6 months of supplementation: 16.6+/-4.8 U/mL and 7.1+/-4.5 U/mL in IgE+ and IgE- infants respectively). No difference in growth rate (increment of weight, length and head circumference) was found, during the entire study, between infants given the almond milk and babies given the soy-based formula or the protein hydrolysate-based formula. Supplementation with the soy-based and protein hydrolysate-based formulas caused the development, in some subjects, of a secondary sensitization (23% to soy-based and 15% protein hydrolysate-based formula), whereas supplementation with the almond milk did not. CONCLUSIONS: Though preliminary, the present findings seem to demonstrate that the almond milk may an efficacious substitute of cow milk in infants with CMA/CMI. One could speculate that some active principles contained in the almond milk could contribute to its beneficial effect observed in CMI/CMA-affected infants.

ABSTRACT

BACKGROUND: The standard procedure for diaphragm reconstruction after extrapleural pneumonectomy for a malignancy consists of the use of prosthetic patches. Our original technique utilizing the reverse flap of the latissimus dorsi is evaluated. METHODS: Once the extrapleural pneumonectomy is performed, the distal portion of the latissimus dorsi, which has been divided with a standard posterolateral thoracotomy at the level of the fifth to sixth rib, is elevated into the chest through the passage obtained by resection of the tenth rib and sutured to the lower pericardium and to the chest wall. Nine patients were evaluated. RESULTS: No operative death occurred. No flap-related complication nor infection was postoperatively assessed. Six patients received adjuvant radiotherapy. No late complication was observed. CONCLUSIONS: The distal latissimus dorsi can be used for total reconstruction of one hemidiaphragm, ensuring a watertight separation between the pleural and peritoneal cavities and avoiding paradoxical respiratory motion. In our opinion, the technique was easier, faster, and more reliable than the standard procedure employing prosthetic materials. We recommend that the procedure be integrated with the standard technique of extrapleural pneumonectomy.

ABSTRACT

The etiology of the Carney's triad (gastrointestinal stromal tumors, pulmonary chondromas, and paragangliomas) is unknown, and only 57 cases have been reported since its identification in 1977. We report the clinical course of a female with the complete triad and some additional tumors. Bilateral vagal paragangliomas were treated surgically and with radiotherapy between the ages of 24 and 26 years. Subsequently she underwent surgery for a gastric leiomyosarcoma (27 years), a pleomorphic adenoma of the parotid gland (49 years) and a multifocal breast cancer with axillary spread (50 years). A calcified lesion was also noticed in the left lung, the radiologic diagnosis of which was consistent with chondroma. A mediastinal paraganglioma, detected at 56 years on a control X-ray of the chest, was partially excised at 63 years. At the last control, performed at 66 years, the patient was alive with residual cervical and mediastinal paraganglioma. Her younger brother was affected by Hirschsprung's disease and died at 54 years of rectal cancer. Her daughter is 33 and has been suffering since birth with severe constipation. In conclusion, this is one of the longest followed-up patients with Carney's triad. Her case illustrates the need for early recognition of the setting in order to detect the component tumors at a stage when surgery may be curative, and careful and life-long follow-up, both because the multicentricity of the classic components tends to manifest metachronously and because of the tendency to develop other tumors, some of which may be malignant. Furthermore, the presence of Hirschsprung's disease in the patient's family, coupled with the alleged common origin of two component lesions from derivatives of the neural crest, open new avenues for the understanding of this disorder.

ABSTRACT

BACKGROUND: Many oncologists have now accepted a combined radiosurgical approach as the treatment of choice in patients with Pancoast tumour but most reports show an incorrect assessment of the disease. METHODS: Stage III lung cancer was classified as Pancoast tumour if the pulmonary extent was limited to the upper apical segment and if at least one of the features of Pancoast syndrome, indicating tumour spread to the para-apical structures, was present. Between 1984 and 1988 15 consecutive patients were treated with primary radiotherapy followed by surgery or with primary excision and subsequent radiotherapy in the absence of an initial histological diagnosis. RESULTS: The mortality of patients given the combined treatment was 6.6% (one death due to pulmonary embolism), and the five year survival rate was 26.6% for all patients and 57% for those who underwent complete resection without N2 disease. Long-term survival was 0% for those cases with incomplete resection, N2 disease, or malignant invasion of the first rib. CONCLUSIONS: Stage III lung cancer, classified as Pancoast tumour according to strict, consistent criteria, is best treated by primary radiotherapy; combined treatment should be used only for patients with potentially resectable cancer without N2 disease and/or malignant invasion of the first rib.

ABSTRACT

OBJECTIVE: Progesterone-induced uterine protein-1, a product of secretory endometrial stromal cells (relative molecular mass 70,000, isoelectric point 5.7), was immunolocalized in endometrium and placenta. STUDY DESIGN: Biopsies were performed to obtain human endometrium and placenta throughout the menstrual cycle and gestation. Formalin-fixed, paraffin-embedded tissues (n = 74) were sectioned and immunohistochemically stained for progesterone-induced uterine protein-1 by the avidin-biotin peroxidase procedure. Isolated endometrial cells were also stained for progesterone-induced uterine protein-1. RESULTS: Progesterone-induced uterine protein-1 localized in proliferative endometrial stroma and in early to midsecretory stroma and ciliated epithelia and vanished from nonpregnant, late-secretory endometrium yet localized in the decidua, syncytiotrophoblast, and intermediate cytotrophoblast during pregnancy. Isolated, cultured endometrial stromal but not epithelial cells displayed progesterone-induced uterine protein-1 staining. CONCLUSION: Endometrial progesterone-induced uterine protein-1 localization shifts from stromal to epithelial, coinciding with the time of ovulation, fertilization, and implantation. This observation, combined with the disappearance of progesterone-induced uterine protein-1 in late-secretory, nonpregnant endometrium and its presence in decidua and trophoblast, suggests that progesterone-induced uterine protein-1 may play a role in decidualization, endometrial or embryo cross-talk, or placental physiologic features.

ABSTRACT

The reliability of polyglyconate monofilament (Maxon) suture for sternal closure was tested on 216 consecutive sternotomies, performed on 208 patients in our department from January 1986 to December 1990. The reason of sternotomy was primary lung cancer in 34 cases (16%), lung metastases in 127 (59%), and disorders of the thymus in 55 (25%). Mean age was 38 years (range 3 to 78 years); multiple lung resections were performed in 102 patients (average 7 lesions, range 2 to 30); maximum extent of the operation was pneumonectomy in 2 cases, lobectomy in 53, segmentectomy in 27, and wedge resection in 74. Prior chemotherapy had been administered in 75 cases (35%). A second sternotomy was performed in 8 cases. No cases of sternal dehiscence, sternal infection, or empyema were observed, after a median follow-up of 27 months. Overall perioperative mortality was 0.9% (2/216). Our series demonstrates the safety of polyglyconate monofilament (Maxon) suture for sternal closure. Absorbable sutures appear to be a safe alternative to steel wire closure in patients undergoing extended pulmonary or mediastinal resection.

ABSTRACT

We have evaluated, in two groups of 50 patients each submitted to axillary dissection for breast cancer (10 mastectomies and 90 conservative procedures), the advantage of the preservation of the minor pectoralis muscle. This muscle was preserved in one group and removed in the other. Whereas in the immediate postoperative period complications (shoulder pain, functional impairment, quantity or duration of serum drainage from the axilla) were the same in the two groups, at longer follow-up (more than 6 months after surgery) the patients whose pectoralis minor muscle was preserved showed a reduction in the incidence of partial atrophy and fibrosis of the pectoralis major muscle. Patients treated with conservation of the pectoralis minor muscle showed this atrophy in 6% of cases vs 54% observed in the other patients. This fact may be related to disruption of the pectoral nerves, which are in close contact with the pectoralis minor during their course from the brachial plexus to the pectoralis major muscle.

ABSTRACT

Between 24 November 1977 and 16 September 1988, 18 consecutive chest wall resections for recurrent breast cancer after failure of radiotherapy, were evaluated as of 1 January 1990. Chest wall involvement was the only site of recurrence in 14 patients (Group I), and the most painful of the multiple recurrences in the remaining four (Group II). Of Group I, chest wall recurrence was local in eight patients (four with necrosis after radiotherapy), regional in four, and distant in two. Chest wall reconstruction was effected by contralateral breast flap in six, by random cutaneous flap in seven and by myocutaneous flap in the remaining five. Cosmetic results were better if both marlex mesh and myocutaneous flap were used. Of Group I, at surgical/pathological staging, one recurrence with sarcomatous findings, two multiple recurrences and residual cancer in all necrosed local recurrences were found: in three of these cases radionecrosis was prominent. Mortality was 0% and surgical morbidity 5%. For Group I, median disease-free interval from mastectomy was extended from 1611 days to 3220 by recurrence resection, and disease-free interval from chest wall resection was 28% cancer-free at 1657 days, without any difference between the local vs regional-distant recurrence. Correlation factor between first and second disease interval was 0.99 and R2 was 0.98. For Group II, survival was 0% at 635 days. Chest wall resection must be considered as an important part of palliative treatment in breast cancer, but the results reflects the biology of the disease more than the chest wall surgery.

ABSTRACT

Between September 1984 and December 1990, seven patients underwent right pneumonectomy and carinal reconstruction. All patients but one had squamous-cell lung cancer. Anterior thoracotomy through the 4th space was the surgical access in all cases. The mean time needed to perform the operation was 190 min and the mean blood infusion 340 ml. There were no intraoperative deaths. Of three deaths, only one was attributable to cancer, while two occurred after 84 and 94 days, respectively, as a result of cardiorespiratory failure. The median disease-free interval was 12 months, but the median survival had not been reached (51%) after a median follow-up of 47 months. Calculation of predicted and observed FEV1 showed that a mean decrease of 286 ml (range 145-439) occurred in the observed FEV1. More attention to pulmonary function is therefore required, and anterior thoracotomy is recommended as the surgical approach.

ABSTRACT

Thrombin promotes the formation of arterial thrombi by converting fibrinogen to fibrin and by causing platelets to aggregate. We have examined the combined effects of plasminogen activators and inhibitors of platelet aggregation on the lysis of platelet-rich fibrin clots formed by alpha-thrombin in citrated platelet-rich plasma. The extent of platelet aggregation and clot formation were measured by recording light transmission in an aggregometer. Immediately after the formation of platelet-rich fibrin clots, addition of 2,000 U/ml streptokinase or 50 micrograms/ml recombinant tissue-type plasminogen activator alone resulted in the degradation of polymerized fibrin and the release of trapped platelet aggregates without causing significant platelet deaggregation. Preincubation of the platelet-rich plasma with 20 microM indomethacin for 1 min before thrombin stimulation or simultaneous addition of prostaglandin E1 (10 microM) with the plasminogen activators after thrombin stimulation resulted in spontaneous platelet deaggregation. Because platelet aggregation is, in part, mediated by the binding of Arg-Gly-Asp-containing adhesive proteins to activated platelets, the effect of Arg-Gly-Asp peptides on platelet deaggregation was examined. By itself, Gly-Arg-Gly-Asp-Ser-Pro specifically caused dose- and time-dependent deaggregation of platelet aggregates formed by ADP or by thrombin in the presence of 1 mM Gly-Pro-Arg-Pro, but had no effect on the dissociation of thrombin-induced platelet-rich fibrin clots. In combination with streptokinase or recombinant tissue-type plasminogen activator, Gly-Arg-Gly-Asp-Ser-Pro enhanced the rate of lysis of platelet-rich fibrin clots. The control Gly-Arg-Gly-Glu-Ser-Pro peptide was completely ineffective.(ABSTRACT TRUNCATED AT 250 WORDS)

ABSTRACT

Among lung tumors, well-differentiated neuroendocrine carcinomas are often misdiagnosed or may go unrecognized. Nineteen cases of well-differentiated neuroendocrine carcinoma (WDNC) were assessed at the National Cancer Institute of Milan over a ten-year period. There was only one woman and the age range was 50 to 77 years. Most of the patients were smokers (83 percent). All tumors were radically resected. There were 12 lobectomies, two sleeve-lobectomies, three bilobectomies, one pneumonectomy, and two segmentectomies (one patient had two synchronous WDNCs). There was neither operative mortality nor major complications. Sixteen tumors were stage 1, three were stage II, and one was stage IIIa. Five patients had adjuvant chemotherapy (cyclophosphamide, doxorubicin, and vincristine [CAV] regimen). One patient was given local or regional radiotherapy. In ten patients the tumors recurred, even though four had had adjuvant treatment. The brain was the first site of metastasis in seven cases. The pathologic stage seemed not to be closely related to the appearance of metastases (six patients with stage I disease had recurrences). Only two patients with recurrence were still alive 12 and 103 months after the procedure. The percentage of survival for patients with stage I disease after more than 100 months was 68 percent. WDNC is similar to small-cell lung carcinoma (SCLC) with regard to the neurotropism of metastases. Surgery is curative for more than one half of the patients with localized disease. Therefore, multimodal therapy, probably based on tumor behavior and investigations of tumor markers, is advisable.

ABSTRACT

In esophageal resections, esophagogastric anastomosis can be performed either at cervical or intrathoracic level. A recent paper showed a greater incidence of postoperative leakages in cervical vs. intrathoracic anastomosis (26% vs. 4%). In the present paper we describe 55 cases of esophagectomy with a modified technique of cervical stapled anastomosis, where the incidence of fistula was 5%.

ABSTRACT

From 1981 to 1986, 17 patients with resected small cell lung carcinoma (SCLC) staged as I or II according to the new TNM classification were recruited for a prospective study to evaluate the effectiveness of surgery and postoperative chemotherapy (plus locoregional radiotherapy only when a nonradical resection was accomplished) in the treatment of early stages of the disease. Six patients received full protocol chemotherapy (6 courses) and 8 a mean of 79.1% of the planned courses. Three patients received non adjuvant treatment. Locoregional radiotherapy for residual disease was administered in 2 cases. One patient died for myelosuppression due to chemotherapy and 10 for recurrences of cancer, all within the 20th postoperative month. Metastases accounted 80% of overall recurrences. Six patients were alive and tumor-free at 18, 22, 39, 44, 47 and 51 months from resection. Actuarial observed 3-year survival was 32%.

ABSTRACT

Out of 52 consecutive patients resected for small cell lung carcinoma (SCLC) from 1976 to 1986, 19 were selected because they underwent nonradical surgery, 10 of them for locoregional spread and 9 for distant metastases. Of the former subset all received postoperative radiotherapy and 8 chemotherapy also. Three patients are alive and disease-free 37, 56 and 91 months after resection. Four patients had a distant recurrence, and 3 a locoregional failure. Patients of the latter subgroup received chemotherapy in 7 instances. None survived more than 16 months, distant metastases being the cause of death. In these patients N0 status was associated with 13.3 months of mean survival, N1 with 8.5 months, and N2 with 6.7 months. Surgery and adjuvant treatments seem effective in achieving local control of SCLC despite nonradical resections. Tumor burden at locoregional sites does not preclude the possibility of long term survival.

ABSTRACT

In breast cancer surgery, axillary dissection is currently considered an essential step. Nevertheless, procedures commonly used include the resection of the pectoralis minor muscle and/or pectoralis nerves. Since 1984 we have performed axillary dissection by sparing both the pectoralis muscles and their nerves. In this paper we present the surgical technique. The comparison of the two groups with clinical N0 N1a assessment, the former of 103 patients submitted to this kind of surgical procedure, the latter (108 women) treated by resection of the pectoralis minor muscle, showed that the mean number of dissected lymph nodes in both procedures was superimposable.
