Learning Invariance From Generated Variance for Unsupervised Person Re-Identification.

This work focuses on unsupervised representation learning in person re-identification (ReID). Recent self-supervised contrastive learning methods learn invariance by maximizing the representation similarity between two augmented views of a same image. However, traditional data augmentation may bring to the fore undesirable distortions on identity features, which is not always favorable in id-sensitive ReID tasks.

[Early debulking surgery after chemotherapy in advanced cancer of the ovary].

The main prognostic factor in advanced ovarian cancer is the volume of residual disease after the initial laparotomy. Early debulking surgery after several cycles of chemotherapy, before the emergence of resistant cell lines, could improve the prognosis of patients with bulky residual disease. This study concerns patients with advanced ovarian cancer entered into three prospective trials including IV cisplatin and anthracycline-based chemotherapy, early debulking surgery after three cycles of chemotherapy in case of initial residual disease superior 2 cm and intraperitoneal consolidation chemotherapy.

Survival with intraperitoneal cisplatin in advanced ovarian cancer after second-look laparotomy.

We studied survival in 36 patients with Stage III/IV ovarian cancer who received intraperitoneal high-dose cisplatin (200 mg/m2) alone or in combination with cytarabine (2 g), after intravenous (i.v.) cisplatin-based chemotherapy followed by second-look laparotomy.

Sequential cisplatin-doxorubicin, early debulking surgery and intraperitoneal chemotherapy in advanced ovarian cancer. Groupe d'Etude et de Recherche sur les Cancers de l'Ovaire et Digestifs (GERCOD).

40 patients with advanced ovarian cancer were treated with immediate debulking followed by sequential cisplatin and doxorubicin every 4 weeks, followed by second-look laparotomy (SLL). Six courses were given when residual disease (RD) was under 2 cm. When RD was over 2 cm, three courses were followed by early debulking and six more courses before SLL.

High-dose folinic acid, 5-fluorouracil bolus and continuous infusion in poor-prognosis patients with advanced measurable gastric cancer.

Twenty-five patients with advanced measurable gastric cancer were treated with high-dose folinic acid (200 mg/m2), 5-fluorouracil bolus (400 mg/m2) and continuous infusion (600 mg/m2) for two consecutive days every two weeks. Fourteen patients over 65 yr old and/or with a poor general status received first-line treatment, and eleven younger patients second-line. The response rate was 43.

[Results of intraperitoneal chemotherapy of ovarian cancer].

We studied a series of 42 patients with advanced ovarian cancer who received intraperitoneal chemotherapy post second-look laparotomy. High-dose cisplatin (200 mg/m2) alone or in combination with cytarabine (2 g) achieved 47% response rate. Median overall survival from second-look laparotomy was 44 months with cisplatin (36 cases), 15 months with carboplatin (600 mg/m2, 5 cases) and not reached at 3 yrs with mitoxantrone (25 mg/m2, 8 cases).

[Functioning of implantable catheters of intraperitoneal chemotherapy].

Intraperitoneal chemotherapy with a totally implantable catheter was performed in 42 patients with advanced ovarian cancer who received 178 courses of chemotherapy administered in 2 l of solution. Major complication was inflow obstruction due to fibrosis around the catheter observed in 10 patients, 23.8% of the cases.

[Cisplatin, adriamycin and mitomycin-C in advanced stomach cancer].

Eighteen patients with advanced gastric cancer were treated with cisplatin 80 mg/m2 d 1, doxorubicin 30 mg/m2 d 3 and mitomycin-C 12 mg/m2 d 3. One complete and 6 partial responses were observed in 17 evaluable patients (41%, confidence interval 17-65%). Median duration of response was 7 months; median survival was 8 months.

High-dose folinic acid and 5-fluorouracil bolus and continuous infusion in advanced colorectal cancer.

An enhanced antineoplastic effect of 5-fluorouracil in patients with advanced colorectal cancer has been produced either by combination with folinic acid or administration by continuous infusion. Thirty-seven patients with advanced measurable colorectal cancer received high-dose folinic acid (LV 200 mg/m2) followed by 5-fluorouracil i.v.

[Peroperative opacification of the terminal portion of the external saphenous vein].

As much as the surgery of the distal end of the internal saphenous vein is simple and followed with good results, the surgery of the distal end of the external saphenous vein remains questionable and followed with varicose veins recurrences. This is the result of numerous anatomical variations of the external saphenous vein as it reaches the deep venous system. In order to ease the dissection of the distal portion of the external saphenous vein, it is important to specify its anatomy.

[Do indications still exist for intra-arterial infiltrations in vascular pathology?].

Intra-arterial infiltrations are a useful therapeutic measure in various vascular diseases where it is important to obtain a lasting and rapid peripheral vasodilatation. In arteritis of the lower limbs, it is paradoxical to match infiltration against surgery. None of these two therapeutic measures can cure completely.

[Fibrocystic deterioration of the popliteal artery. Apropos of 1 case].

Set off by a sports movement, a subacute ischemia of the lower limb allowed the delayed discovery of a segmental stenosis of the popliteal artery in a young man. It involved a compression by fibro-cystic deterioration of the wall of the artery. Separation of the cyst from the diseased arterial wall was followed by the restoration of circulation by means of an internal saphenous vein graft.

[Surgical approach to a leg ulcer in areas of subcutaneous calcinosis].

The medical treatment of ulceration of the legs in areas with a subcutaneous plaque of calcinosis is often unsuccessful. The phlebologists then refer the patient to a surgeon. A patient aged 58 years, with a previous history of phlebitis, presented on two successive occasions with ulceration in the area of a large calcification in the lower third of the left leg.

[General surgeon's approach to deep phlebitis of the leg].

The therapeutic problems of the general surgeon, faced with a case of deep phlebitis of the lower limbs, differ according to whether it is diagnosed before or after surgery. If possible, pre-surgical phlebitis should be treated before the operation. Heparinotherapy remains the basic treatment.
