[Early vs delayed cholecystectomy for acute cholecystitis].

The timing of cholecystectomy in acute cholecystitis is still controversial. A marked change toward early surgery has been noted in the past decade. In a retrospective study of 197 patients we evaluated the results of cholecystectomy in 117 who underwent elective cholecystectomy, and in 80 operated on during the acute phase of cholecystitis. The diagnosis of acute cholecystitis was by isotope scan (HIDA) or ultrasound. There was no case of misdiagnosis. 3 patients died postoperatively: 2 in the early operation group (1 had emergency cholecystectomy) and 1 in the elective group. Postoperative complications were more frequent in the early surgery group (p = 0.06). The highest morbidity was in early cholecystectomy in those older than 60 years who had cardiovascular disease (p less than 0.0002). Hernia in the scar was a unique complication of the early operation. According to most studies reviewed, early operation eliminates the need for emergency operation when conservative treatment fails, without increasing morbidity or mortality. Therefore, early operation during the acute phase of cholecystectomy is advised. For patients older than 60 years who have cardiovascular disease, we recommend delaying surgery until the acute inflammation subsides. The waiting period before surgery should be as short as possible in order to reduce the risk of recurrent cholecystitis and its complications.

[Immediate breast reconstruction with tissue expander].

The technique of immediate breast reconstruction, using the tissue expander and replacing it with a permanent silicone prosthesis, has been applied with increasing frequency during the past several years. We chose this technique for immediate breast reconstruction because of its simplicity, rapidity when combined with mastectomy, and good esthetic results. We have performed 29 immediate breast reconstructions in the past 1.5 years in patients ranging from 22 to 72 years (mean 47). The insertion of the tissue expander added only 20-30 minutes of operating time for the mastectomy, and did not prolong hospitalization. Before we began to replace the expander with a permanent silicone prosthesis there were complications in 4 patients (14%). These included development of a seroma in 3, 1 of which became infected 40 days after insertion of the tissue expander, and capsular contraction in a patient who had previously had radiotherapy to her breast. The case with the infection was the only failure and the expander had to be removed. Immediate reconstruction of the breast is easily performed and can be of tremendous psychological benefit to mastectomy patients. Chemotherapy or radiotherapy are not contraindications to this type of reconstruction.

Non-linear intestinal absorption kinetics of cefadroxil in the rat.

Absorption of cefadroxil in a selective intestinal absorption area (the proximal third of the small intestine) of the anaesthetized rat, at seven initial perfusion concentrations, ranging from 0.01 to 10.0 mg mL-1, is shown to be a non-linear transport mechanism. With the aid of computer-fitting procedures based on differential and integrated forms of Michaelis-Menten equation, Vm and Km values of 36.7-37.3 mg h-1 and 12.0-13.0 mg, respectively, were found. The statistical parameters were better than those obtained both for first-order and for combined Michaelis-Menten and first-order kinetics. There is no evidence for substantial passive diffusion processes. The results reported here, together with allometric considerations and literature data analysis, may help to explain some particular non-linear features of plasma level curves associated with the administration of fairly high oral doses of cefadroxil to humans.

Necrotizing fasciitis: early awareness and principles of treatment.

Necrotizing fasciitis is a serious life-threatening disease. A series of 11 patients with this disease is described, with emphasis on clinical diagnosis, initiating factors, associated diseases, etiologic pathogens and treatment. The following conclusions can be drawn from this report: Escherichia coli was the most prominent single pathogen, hyperbaric oxygen did not show any added beneficial effect, and diabetes mellitus did not affect morbidity and mortality. There is no doubt that aggressive and radical surgical excision and repeated debridement, combined with i.v. antibiotics and hyperalimentation, are essential to achieve a favorable outcome in this fulminant disease.

[Lymphedema of the limb: predictors of efficacy of combined physical therapy].

BACKGROUND: Limb lymphedema results from incompetence of the lymphatic system, and treatment of both primary and secondary forms involves manual lymphatic drainage and support. The effectiveness of treatment varies from patient to patient and can be unpredictable. OBJECTIVE: To investigate clinical and paraclinical criteria able to predict responses to combined physical treatment (lymphatic drainage and multilayered support) during hospitalization. PATIENTS AND METHODS: A retrospective study was performed in 45 patients admitted for one week's intensive treatment of limb lymphedema in the Lymphology Unit of the Department of Dermatology of the University Hospital of Tours. Lymphoscintigraphy was performed for all patients on admission. Loss of volume in affected limbs was studied to evaluate the effectiveness of treatment. RESULTS: Two criteria were predictive of resistance to combined treatment, i.e. venous insufficiency and continuing lymph node evidence of scintigraphic activity four hours after lymphoscintigraphy. The two factors were significantly related. CONCLUSION: Failure of combined physical treatment for lymphedema appears to be related to venous insufficiency. It is therefore essential to investigate and treat venous insufficiency, particularly in patients with continuing evidence of scintigraphic activity in lymph nodes.

The decisive role of fine needle aspiration cytology in the preoperative work-up of breast cancer.

During an 18-mo period, 760 palpable mammary lesions were examined and aspirated. When indicated, mammography was performed in addition. Three separate aspirations were performed in each lesion utilizing 23 gauge (0.6 mm) needles. Biopsies were performed following aspiration in 206 lesions; and 470 of the cases in whom biopsies were not performed were followed up clinically for periods of 10 to 26 mo (mean period 15 mo). Accuracy and sensitivity of the cytological examination were found to be far higher than that of clinical evaluation or mammography. Aspiration cytology resulted in only 1.5% false negative, no false positive, and only 1.65% inconclusive reports. On the other hand, clinical evaluation and mammography yielded 35 and 29% false negative, 0.3 and 0.8% false positive, and 6.75 and 8.8% inconclusive findings, respectively. Eleven malignant cases that were considered to be benign both clinically and mammographically, were correctly diagnosed cytologically. Aspiration cytology was found to be the most accurate of the preoperative diagnostic methods.
