Abstract
OBJECTIVE To analyze outcomes of singleton pregnancies with idiopathic polyhydramnios through a systematic review and meta-analysis. METHODS Electronic databases, including MEDLINE, OVID, EBSCO, Cochrane collection and Science Citation Index, were searched from 1946 to 2019. Gray literature and tables of contents of relevant journals were also screened. Prospective and retrospective studies with a control group were included. Two authors independently reviewed the abstracts retrieved from the literature search. Inclusion criteria were: studies documented in English, singleton pregnancy and idiopathic polyhydramnios determined by amniotic fluid volume assessment on ultrasound. Exclusion criteria were: maternal diabetes, fetal structural or chromosomal anomaly, alloimmunization and intrauterine fetal infection. RESULTS Twelve studies met the inclusion criteria, giving a total of 2392 patients with idiopathic polyhydramnios and 160 135 patients with normal amniotic fluid volume. Pregnancies complicated by idiopathic polyhydramnios were at a higher risk of neonatal death (odds ratio (OR), 8.68 (95% CI, 2.91-25.87)), intrauterine fetal demise (OR, 7.64 (95% CI, 2.50-23.38)), neonatal intensive care unit admission (OR, 1.94 (95% CI, 1.45-2.59)), 5-min Apgar score < 7 (OR, 2.21 (95% CI, 1.34-3.62)), macrosomia (OR, 2.93 (95% CI, 2.39-3.59)), malpresentation (OR, 2.73 (95% CI, 2.06-3.61)) and Cesarean delivery (OR, 2.31 (95% CI, 1.79-2.99)). CONCLUSIONS This study suggests that pregnancies complicated by idiopathic polyhydramnios are at increased risk of adverse outcome. Future investigations should aim to determine an amniotic fluid volume threshold above which antenatal fetal surveillance is appropriate in the management of these pregnancies. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Aim The aim of our study was to evaluate the role of scintigraphy in lymphatic mapping and in the identification of the sentinel lymph node (SLN) in patients with head and neck cancer. Methods Between September 1999 and February 2001 we enrolled 22 consecutive patients with cancer in the head and neck region: five squamous cell carcinomas, one Merkel cell tumor of the cheek, and 16 malignant melanomas. Lymphoscintigraphy was performed three hours before surgery after injection of 30-50 MBq of 99mTc-Nanocoll in 0.3 mL; the dose was fractionated by injecting the radiotracer at two points around the lesion. Static acquisition (anterior and/or lateral views, 512 × 512 matrix, 5 mins pre-set time) was started immediately after the injections so as to visualize the pathways of lymphatic drainage. The skin projection of the SLN was marked with ink. Intraoperative SLN detection was performed with perilesional injection of patent blue. Results SLNs were found with lymphoscintigraphy in all patients. Thirty-three SLNs were identified: one occipital node, three nodes at the base of the tongue, 10 superficial lateral nodes (external jugular), five submandibular nodes, five submental nodes, three mastoid nodes and six supraclavicular nodes. Biopsy was performed in 21/22 patients. In 20/22 patients the first lymph nodes were visualized in the proximal cranial regions (retroauricular, jugular and submandibular) at five minutes post injection. The SLN positivity rate was 13.6% (three patients). All patients with tumor-positive SLNs were submitted to radical dissection. Poor concordance in the detection of sentinel nodes was observed with patent blue. Conclusions The flow of nanocolloid in the lymph vessels of the head is rapid. In our experience immediate scintigraphic imaging was essential to visualize the pathways of lymphatic drainage and the first SLN. Radioguided SLN biopsy is therefore recommended within three hours. Injection of patent blue is inadvisable because of the poor concordance with lymphoscintigraphy and the risk of permanent tattooing of the face.

Abstract
Evolutionary adaptations are occasionally convergent solutions to the same problem. A mutation contributing to a heat tolerance adaptation in Senepol cattle, a New World breed of mostly European descent, results in the distinct phenotype known as slick, where an animal has shorter hair and lower follicle density across its coat than wild type animals. The causal variant, located in the 11th exon of prolactin receptor, produces a frameshift that results in a truncated protein. However, this mutation does not explain all cases of slick coats found in criollo breeds. Here, we obtained genome sequences from slick cattle of a geographically distinct criollo breed, namely Limonero, whose ancestors were originally brought to the Americas by the Spanish. These data were used to identify new causal alleles in the 11th exon of the prolactin receptor, two of which also encode shortened proteins that remove a highly conserved tyrosine residue. These new mutations explained almost 90% of investigated cases of animals that had slick coats, but which also did not carry the Senepol slick allele. These results demonstrate convergent evolution at the molecular level in a trait important to the adaptation of an animal to its environment.

Abstract
Postweaning serum insulin-like growth factor-I (IGF-I) concentrations and serum IGF binding proteins (IGFBP) were investigated in 68 (1992 Fall-born) and 84 (1999 Fall-born) Angus cattle selected for either high or low serum IGF-I concentrations since 1989. Relative serum levels of IGFBP were determined by [125I]IGF-I Western ligand blotting. IGFBP species of 38-42, 34, 30, and 24 kDa were identified. The 34 kDa species was identified as IGFBP-2 by immunoblot analysis. No significant line effects were observed for any of the IGFBP. In both 1992 and 1999, heifers had higher IGFBP-2 levels than bulls (P<0.0005). In 1992 calves, relative levels of the 38-42 and 24 kDa species were significantly correlated with serum IGF-I concentration. In 1999 calves, none of the IGFBP were correlated with serum IGF-I, although IGFBP-2 was negatively correlated with several measures of body weight. No significant line effects were observed for growth or serum IGF-I traits in 1992 calves. However, 1999 high line calves had higher serum IGF-I concentrations and body weights than low line calves (P<0.05). In both 1992 and 1999 calves, bulls had higher serum IGF-I concentrations and body weights than heifers (P<0.05). Thus, while selection for high versus low serum IGF-I concentrations has resulted in divergence between the selection lines and also in changes in body weights, it has not resulted in changes in serum IGFBP levels. Furthermore, circulating IGFBP-2 appears to be higher in heifers than in bulls, and also appears to be negatively correlated with body weights.

Abstract
PURPOSE To optimize the lymphoscintigraphic procedure in the staging of malignant cutaneous melanoma. MATERIAL AND METHODS Fifty-five patients (21 men and 34 women) were enrolled. Breslow thickness of the lesions ranged 0.75-1 mm (Clark III-IV) to 1-4 mm. Lymphoscintigraphy was performed with a large-view gamma camera equipped with a low-energy general purpose collimator, two weeks after melanoma excision. A single perilesional dose of 30-50 MBq nanocoll-Tc99m (volume 0.2-0.3 mL) was injected 18 hours before surgery (6 hours in head localizations). After injection a gentle local massage was applied. A planar static scintigraphy (matrix 512 x 512, pre-set time 5 min) in anterior and/or oblique view(s) was obtained 5-10 min after radiotracer injection. The skin projection of the first node was stained with an external radioactive marker. Fifteen minutes before surgery a blue-vital dye was injected around the lesion. A radioguided biopsy of the sentinel node was performed. RESULTS The site of the sentinel node was typical in 80% of patients. Two or three nodes were identified in 20% of patients. An unexpected node site was detected in 9% of patients. The total rate of micrometastasis to the sentinel node was 14.7% but significant differences were observed relative to the melanoma thickness. CONCLUSIONS Preoperative scintigraphy increases the accuracy of sentinel node identification in unusual lymphatic drainage pathways, in unexpected sites and in fast lymphatic drainage. Radioguided biopsy reduces surgical time, requires only local anesthesia and permits shorter hospitalization.
