Leaf Symptoms

Lettuce big-vein disease (LBVD) is a widespread problem in commercial lettuce producing areas. It was first reported in 1934 in California. In the United States in 2009, it was estimated that 100% of all commercial lettuce production was concentrated in California (in early spring) and Arizona (in winter). The disease also occurs worldwide, particularly in regions in Australia, Europe, Brazil, and New Zealand, and at high altitudes in subtropical regions. LBVD often results in decreased yield from infected plants, mainly in winter growing seasons. Symptoms of this disease are the obvious chlorophyll clearing, which causes the big-vein leaf symptoms from which the disease gets its name, along with crinkled leaves and a reduced head size, which is often oblong in shape. LBVD is associated with a complex of two viruses, Lettuce big-vein associated virus (LBVaV) and Mirafiori lettuce big-vein virus (MLBVV). Motile zoospores of Olpidium virulentus vector LBVaV and MLBVV to the roots of healthy plants and, in the absence of susceptible hosts, its resting spores retain the ability to harbor these viruses for decades in infested soil and in dry roots for 39 months. The ability of viruliferous resting spores to persist in production areas for such extended periods of time, and also the motility of viruliferous zoospores, pose significant difficulties for the management and/or control of the disease.

The objective: to evaluate the results of planned open surgical interventions (POSI) in pregnant women with primary symptomatic chronic vein disease (PSCVD). Materials and methods. The study included 457 pregnant women operated on a routine basis with PSCVD. The patients underwent ultrasound duplex angioscanning (USDA) of the veins of the lower extremities, inguinal canals, and iliac veins. The severity of the clinical manifestations of PSCVD was evaluated on a VCSS scale. With the help of the circadian visual-analog scale, the dynamics after the operative pain were studied. The effect of POSI on uterine tone and cardiac function of the fetus was investigated using cardiotocography. When forming the results for POSI, data from USDA, the severity of clinical and cosmetic manifestations of PCVD, the need for active prevention of thrombophlebetic, thromboembolic and hemorrhagic complications, minimization of surgical childbirth were taken into account. The results of treatment were studied in 2 groups of patients. Patients of the first group were treated with conservative therapy, the second group – POSI. Parametric indicators, which were presented as mean and standard error M(SD), were used for statistical data processing of the study, and their reliability was estimated using Student’s t-test. The species was determined to be significant at p<0.05. Results. 495 POSI were performed at 28-38 weeks gestation in an obstetric hospital (perinatal center), by a vascular surgeon from the staff of the center, who was familiarized with the peculiarities of working with this contingent of patients. Surgery was performed under local anesthesia in 346 (75.49%) pregnant women at one extremity, in 111 (24.51%) – at two in one session. According to the results of the study, it was noted that in the first group 33.7% of patients had a positive clinical result due to the reduction of pain syndrome, while 67.5% of patients had an increase and spread of varicose transformation in the area of saphenous and/or non-saphenous veins with spread of pathological venous reflux in the distal direction. 78% of patients had the need to administer prophylactic doses of low molecular weight heparins, both during pregnancy and in postpartum period. Out of 126 pregnant women with pronounced varicose veins of the external genital organs and perineum in 36 (28.6%) deliveries were performed by caesarean section. In 9 (3%) patients there was an acute thrombophlebitis of the subcutaneous veins of the lower extremities, which required 5 pregnant women to undergo urgent surgery when the inflammatory process had spread to the middle and above along the femoral vein of the large subcutaneous vein. Pregnant women of the second group with PSCVD on the basis of obstetric hospital (perinatal center) POSI were performed in the organization, which laid the ideology of the FTS program, strictly individual indications for intervention in the optimal terms of pregnancy, multidisciplinary management of patients, due to this in 93% of operated patients regression of clinical manifestations of the disease was noted, whch contributed to the correct and safe delivery of pregnancy with 100% absence of preterm birth, abnormalities in fetal development, pregnancy course, negative impact on obstetric and somatic condition of the pregnant woman. No hemorrhagic, thrombophlebic, thromboembolic complications were noted. Patients in the postoperative period did not require medical support, as during the period of pregnancy, during delivery and in the postpartum period. There were no indications for surgical delivery. 2.4% of patients experienced complications of post-operative wounds in the form of cheese, which had no effect on pregnancy and was eliminated before delivery. In the postoperative period, if necessary, it was recommended to use elastic compression class garments 1–2. Conclusion. POSI made at PSCVD in optimal terms of pregnancy in a specialized obstetric hospital by a vascular surgeon in strictly individual indications is safe, both for the fetus and the pregnant woman. It is promising to further study the results of POSI in pregnant women with PSCVD to introduce it into the arsenal of treatment of this pathology. Key words: FTS ideology, planned open surgical interventions in pregnant women.
