Arterial Branch

Calibre-persistent labial artery (CPLA) is a commonly underdiagnosed vascular lesion of the lip. CPLA is an arterial branch that penetrates the submucosal tissue without loss of calibre. Clinical diagnosis is significant as misdiagnosis can lead to profuse haemorrhage following an excisional biopsy or surgical excision. Colour Doppler ultrasonography is a safe and non-invasive diagnostic tool to confirm the diagnosis. Here, we report a case of a 24-year-old man who complained of an asymptomatic pulsating non-progressive nodule on the left side of upper lip initially diagnosed as peripheral angiomatous lesion. Diagnosis was confirmed by high-resolution Colour Doppler Ultrasonography. The purpose of this case report is to highlight the clinical importance and diagnosis of a rarely reported soft tissue swelling of the lip to the attention of clinicians.

Selection Of

Colour-Doppler ultrasonography (CDU) has been applied for a more detailed examination of the ovary and uterus, mainly local blood flow in ovarian follicles and the corpus luteum (CL). The main use of CDU is for the diagnosis of early pregnancy or the selection of recipients for embryo transfer in cattle; however, this tool can also be used to select oocyte donors according to blood flow to the ovary. The concept is that more blood flow in the ovary is conducive to a healthier intraovarian environment (e.g. higher progesterone levels and removal of reactive oxygen species), yielding higher quality oocytes. The objective of this research was to evaluate invitro embryo production (IVP) after selection of oocyte donors, considering ovary irrigation before ovum pickup (OPU). The research was carried out in the reproduction laboratory at the Palominos Ranch (Jalisco, México). The oocyte donors (n=15) were synchronized before each round of OPU using an intravaginal device (1.9g of progesterone) with oestradiol benzoate (2mg) and cloprostenol sodium (500µg) on Day 0, to avoid the presence of a corpus luteum and to synchronize the follicular wave. On Day 6, the intravaginal device was removed and OPU was performed. All Angus breed donors between 3 and 5 years old with a body condition score between 5–6 (scale 1–9, where 1 is extremely thin and 9 is very obese) and were evaluated with transrectal CDU (Sonoscape S2™) with a linear-array probe (7.5MHz) before the first OPU session only. The oocyte donors were classified subjectively into three categories: low blood flow (LBF, ∼30% ovarian area), median blood flow (MBF, ∼50% ovarian area), and high blood flow (HBF, ∼70% ovarian area) and were submitted to 3 cycles of IVP each (45 total cycles). Semen from a proven bull for IVF was used during all IVP cycles. All oocytes collected from each donor were used in IVF with the same semen in all IVP cycles. The total oocytes collected, and percentages of viable oocytes, cleavage, and blastocysts on Day 7 of culture were evaluated. Statistical analysis was carried out using the GLM procedure of SAS software (version 9.3; SAS Institute Inc.) to evaluate the results of LBF, MBF, and HBF (P-value=0.05). Total oocyte recovery was 11.28±1.92, 10.06±1.31, and 15.52±1.05 for HBF, MBF, and LBF, respectively, being significantly higher for LBF (P<0.05). There were no differences in viable oocytes among groups. Cleavage rates were 53.04%±3.43 for HBF, 43.18%±2.34 for MBF, and 43.69%±1.89 for LBF, being significantly higher for HBF (P<0.05). Percentage of blastocysts on Day 7 was 38.16%±3.80 for HBF, 30.11%±2.60 for MBF, and 17.78%±2.10 for LBF. This value tended to be significantly higher for HBF than MBF, and both were significantly superior to LBF (P<0.05). In conclusion, under the conditions of this research, although LBF donors had more total recovered oocytes, blastocyst rates were increased in HBF and MBF donors. Therefore, based on the results of the present study, CDU can be a useful tool for the selection of oocyte donors.

The objective was to determine the incidence of false-positive pregnancy diagnosis following the use of colour Doppler ultrasonography 20 and 22 days after fixed-time AI (FTAI) in Bos indicus heifers submitted to resynchronization 14 days after first FTAI. In the study, 512 Nellore heifers at 24.5±0.8 months of age and body condition score of 3.4±0.1 were used beginning 14 days after FTAI. On Day 14, heifers received 50mg of short-acting progesterone (Afisterone®, CEVA, São Paulo, Brazil) and a progesterone device (Prociclar®, CEVA). Eight days later (Day 22), the progesterone device was removed. A duplex B-mode (grayscale) and pulse-wave colour Doppler ultrasound instrument (M5, Mindray, Shenzhen, China) equipped with a multifrequency linear transducer was used for the examination of luteal blood flow on Days 20 and 22. The percentage of luteal area with colour Doppler signals of blood flow at each examination was determined as previously described (Ginther 2007) and was classified as low [corpus luteum (CL) with less than 25% vascularized area], intermediate (CL with 25-75% vascularized area), or high (CL with more than 75% vascularized area). Heifers with intermediate and high luteal blood flow were diagnosed as pregnant by Doppler ultrasonography, and heifers with low luteal blood flow were diagnosed as nonpregnant. Heifers diagnosed as pregnant by Doppler ultrasonography were examined 30 days after FTAI by B-mode ultrasound examination for pregnancy diagnosis and to determine the number of false positives (heifers pregnant by Doppler ultrasonography and nonpregnant by B-mode ultrasonography). Statistical analysis was performed by the GLIMMIX procedure of SAS (SAS Institute Inc., Cary, NC, USA). Pregnancy rate by Doppler ultrasonography [Day 20=60.5% (310/512), Day 22=55.3% (283/512); P=0.10] and false-positive percentage [Day 20=29.7% (92/310), Day 22=23.0% (65/2830); P=0.06] were similar on pregnancy diagnoses by Doppler ultrasonography performed 20 and 22 days after FTAI. Furthermore, in the period from 20 to 22 days after FTAI, luteolysis was verified in 5.8% (30/512) of heifers. In conclusion, anticipation of pregnancy diagnosis in 2 days by evaluation of luteal blood flow with colour Doppler ultrasonography (20 days after FTAI) does not interfere with pregnancy rate by Doppler ultrasound and percentage of false positives in Bos indicus heifers.
