Review
OBJECTIVES
Mirror syndrome (MS) is a condition characterized by the presence of maternal, fetal, and placental edema and is reversible through delivery or pregnancy termination. As fetal hydrops itself may be amenable to treatment, we sought to determine outcomes for MS primarily managed by fetal therapy through a narrative review of the literature and cases managed at our fetal center.
STUDY DESIGN
PubMed, Embase, Web of Science, Scopus, and Google Scholar databases were searched through January 2024 using key words: mirror syndrome, Ballantyne's syndrome, fetal hydrops, maternal hydrops, pseudotoxemia, triple edema, maternal recovery, fetal therapy, and resolution. Manuscripts describing primary management by fetal therapy that included maternal and fetal outcomes were identified. Clinical details of MS patients managed with fetal therapy at our center were also included for descriptive analysis.
RESULTS
16 of 517 manuscripts (3.1%) described fetal therapy as the primary intended treatment in 17 patients. 3 patients managed at our center were included in the analysis. Among 20 patients undergoing primary fetal therapy for management of mirror syndrome, median gestational age of presentation was 24 weeks and 5 days gestation; predominant clinical findings were maternal edema (15/20), proteinuria (10/20), pulmonary edema (8/20), and hypertension (8/20); the primary laboratory abnormalities were anemia (8/20) and elevated creatinine or transaminases (5/20). Condition-specific fetal therapies led to resolution of hydrops in 17 (85%) cases and MS in 19 (95%) cases. The median time to hydrops resolution was 7.5 days and to resolution of mirror syndrome was 10 days. Fetal therapy prolonged pregnancy by a median of 10 weeks with a median gestational age of 35 weeks and 5 days at delivery. All women delivered for indications other than mirror syndrome and 19/20 fetuses survived.
CONCLUSION
In appropriately selected cases, MS often resolves after fetal therapy of hydrops allowing for safe pregnancy prolongation with good maternal and infant outcomes.

is a colonial benthic hydroid from the Class Hydrozoa (Phylum Cnidaria) distributed in the tropical and subtropical marine waters from Atlantic Ocean, Indo-Pacific, and Mozambique. Its colonies somewhat resemble plants, causing confusion in the bathers who accidentally touch the animal. Acute burning/local pain, edema, erythema, and pruritus were symptoms already described, but its venom composition is unknown, as well as the participation of toxins for the symptom's development. Thus, herein, we show the biochemical composition and toxic effects of venom. Colonies were collected and processed for histological analysis; alternatively, they were immersed into methanol containing 0.1% acetic acid for venom attainment, which was analyzed by mass spectrometry and submitted to edema and nociception evaluation in mice, hemolysis and antimicrobial assays . Before the molecule's extraction, it was possible to see the inoculation structures (hydrocladiums and hydrotheca) containing venom, which was released after the immersion of the animal in the solvents. The venom was composed mainly by low molecular mass compounds, able to cause significant reduction of the paw withdrawal latency from the hot plate test, 30 minutes after the injection. Moreover, significant edema was observed 10 and 30 minutes after the injection, indicating the activity of at least two inflammatory mediators. The venom caused no hemolytic activity but reduced the growth of and strains. This study is the first biochemical description of venom, with molecules that cause fast inflammatory and painful effects, characteristic of the envenomation.

Review
There is no formally defined terminology for the related entities transient osteoporosis of the hip (TOH), localized or regional migratory osteoporosis (RMO) and bone marrow edema syndrome (BMES). This study aimed to map the diversity and frequency of diagnostic terms and vocabulary utilized in the literature. A comprehensive search of electronic databases and reference lists was conducted. Publications that reported on patients with TOH, RMO, BMES, or related variants were eligible for inclusion. The terminologies were categorized based on the wording of the titles, abstracts, or texts. We included 561 publications, of which 423 were case reports, involving 2921 patients. Overall, TOH was the most commonly used term, occurring in 257 (45.8%). RMO was used in 34 (6.1%) and BMES in 57 (10.2%). The remaining used various combinations of transient, migratory, and regional in conjunction with either osteoporosis or bone marrow edema. Localized osteoporosis was not used. We identified three different terms related to pregnancy. In 76.3% of the publications, the terminology was related to osteoporosis and in 18.2% to bone marrow edema, although terminology did not correspond to actual findings. Bone marrow edema occurred as often as osteoporosis, and osteoporosis was generally ascertained by visual inspection of radiographs, seldom by bone densitometry. Many publications used osteoporosis-related terms without evidence that osteoporosis had been detected. The terminology of these closely related entities is confusing and unstandardized. The lack of formal definitions impedes accurate diagnosis, research on disease mechanisms, and effective treatment.

The objective of the present study was to enhance the transdermal permeation of cannabinoids: cannabidiol (CBD), cannabigerol (CBG) and tetrahydrocannabivarin (THCV) using chemical permeation enhancer approach and evaluate them for their anti-inflammatory effect in vivo in a paw edema model in rats. Cannabinoids gel formulations were developed using FDA approved inactive ingredients: lactic acid (LA), polyethylene glycol-400 (PEG-400), N-methyl-2 pyrrolidone (NMP), dimethyl sulfoxide (DMSO). In vitro skin permeation testing (IVPT) showed flux of ∼ 13.25 μg/cm/h for CBD, ∼9.38 μg/cm/h for CBG and ∼ 51.74 μg/cm/h for THCV. Additionally, IVPT study showed cumulative drug permeation of 610.96 ± 88.92 μg/cm, 432.09 ± 35.59 μg/cm and 2384.44 ± 42.22 μg/cm from CBD, CBG and THCV gel formulations respectively. Further, effect of excipients on cannabinoid permeation showed that, formulation containing lactic acid, NMP and DMSO showed significantly (p < 0.0001) enhanced flux of cannabinoids as compared to formulation without LA, NMP and DMSO. In vivo studies showed that paw edema was significantly (p < 0.0001) reduced in the groups containing CBD, CBG, THCV as compared to control and placebo formulation. In conclusion, flux of CBD, CBG and THCV was significantly enhanced using chemical permeation enhancers approach which helped in reducing rat paw edema.

Phytochemical analysis and preclinical toxicological, antioxidant, and anti-inflammatory evaluation of hydroethanol extract from the roots of Harpalyce brasiliana Benth (Leguminosae).
ETHNOPHARMACOLOGICAL RELEVANCE
Harpalyce brasiliana Benth (Leguminosae) is a shrub endemic to Brazil, popularly known as "snake's root." This species is used in folk medicine for the treatment of inflammation and snakebites. However, up to now there is no scientific research to justify its popular use. The study aimed to characterize the phytochemical profile of the hydroethanol extract from the roots of H. brasiliana (Hb), to evaluate its antioxidant and anti-inflammatory potential, as well as to investigate its cytotoxicity and acute toxicity.
MATERIALS AND METHODS
The extract was obtained by maceration method using a solution of ethanol:water (70: 30, v/v). The phytochemical profile was obtained by liquid chromatography coupled to mass spectrometry. The cytotoxicity of extract (31-2000 μg/mL) was evaluated in vitro, by the 3-methyl-[4-5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) method using murine macrophage and fibroblast cell lines (RAW 247.6 and 3T3, respectively) and by the hemolytic assay. For the in vivo acute toxicity, the extract (2000 mg/kg) was administered and after 14 days the weight (body and organs) and hematological and biochemical parameters were analyzed. Chemical free radical scavenging effect of the extract (125-2000 μg/mL) was investigated through diphenylpicryl hydrazine reduction, total antioxidant capacity, reducing power, hydroxyl radical scavenging, and iron and copper chelating assays. In vitro anti-inflammatory effect of the extract (125, 500, and 2000 μg/mL) was demonstrated through of nitric oxide (NO) analyzed in lipopolysaccharides stimulated RAW 264.7 cells. In vivo anti-inflammatory activities were evaluated in carrageenan-induced paw edema and zymosan-air-pouch models, with gavage administration (post-treatment) of extract at 100, 200, and 400 mg/kg. For the first animal model, the anti-edematogenic activity and myeloperoxidase (MPO) levels were investigated, while in the zymosan-air-pouch model the leukocyte number, MPO, total protein and pro-inflammatory cytokine (IL-1β, IL-6, and TNF-α) levels were quantified. In addition, the oxidative parameters such as malondialdehyde (MDA) and reduced glutathione (GSH) were determined.
RESULTS
The phytochemical profile revealed the presence of 20 compounds, mainly prenylated and geranylated pterocarpans. The extract demonstrated no cytotoxicity in erythrocytes, macrophages and fibroblasts cells at the tested concentrations, as well as no sign of toxicity and mortality or significant alterations on the hematological and biochemical parameters in the acute toxicity model. The extract was also able to neutralize chemical free radicals, with copper and iron chelating effect. For the NO dosage, the extract evidenced the reduction of expression of NO after the administration of the extract (500 and 2000 μg/mL). The edematogenic model revealed a decrease in paw edema and MPO level, while the zymosan-air-pouch model evidenced a reduction of leukocyte number (especially of polymorphornuclears), MPO production, and total protein and cytokine levels, and demonstrated the antioxidant effect through a decrease in MDA and increase in GSH parameters.
CONCLUSION
This approach demonstrates for the first time that Hb is not cytotoxic, has low acute toxicity, and possesses antioxidant and anti-inflammatory properties in preclinical analyses, corroborating its popular use.

BACKGROUND
Hydrops foetalis is defined as excessive fluid accumulation within the foetal extravascular compartments and body cavities. It has been described in human and veterinary medicine, but despite several descriptive studies its aetiology is still not fully clarified. Pulmonary hypoplasia and anasarca (PHA) syndrome is a rare congenital abnormality in cattle that is characterised by hydrops foetalis including extreme subcutaneous oedema (anasarca) and undeveloped or poorly formed lungs (pulmonary hypoplasia). Until now, sporadic cases of PHA were reported in cattle breeds like Australian Dexter, Belted Galloway, Maine-Anjou, and Shorthorn. This report describes the first known cases of PHA syndrome in Slovenian Cika cattle.
CASE PRESENTATION
A 13-year-old cow aborted a male calf in the seventh month of pregnancy, while a male calf was delivered by caesarean section on the due date from a 14-year-old cow. The pedigree analysis showed that the calves were sired by the same bull, the dams were paternal half-sisters and the second calf was the product of a dam-son mating. Gross lesions were similar in both cases and characterized by severe anasarca, hydrothorax, hydropericardium, ascites, hypoplastic lungs, absence of lymph nodes, and an enlarged heart. The first calf was also athymic. Histopathology of the second affected calf confirmed severe oedema of the subcutis and interstitium of the organs, and pulmonary hypoplasia. The lymph vessels in the subcutis and other organs were severely dilated. Histopathology of the second calf revealed also lack of bronchus associated lymphoid tissue and adrenal gland hypoplasia.
CONCLUSIONS
The findings were consistent with known forms of the bovine PHA syndrome. This is the first report of the PHA syndrome occurring in the local endangered breed of Cika cattle. Observed inbreeding practice supports that this lethal defect most likely follows an autosomal recessive mode of inheritance. In the light of the disease phenotype it is assumed that a mutation causing an impaired development of lymph vessels is responsible for the hydrops foetalis associated malformations in bovine PHA.

Alloferon-1 have been proposed as an effective peptide to enhance antitumoral immunity, antiviral defense and anti-inflammatory activity. This work aimed to assess anti-inflammatory effects of alloferon-1 against acute inflammation and histopathological deformations in λ-carrageenan-induced paw edema in mice. Systemic pretreatment with alloferon-1 (22.0 mg/kg) intraperitoneally injected mice showed a significant reduction in paw thickness and vascular permeability. Alloferon-1 prevented λ-carrageenan-evoked exudation and the neutrophil influx to the mouse pleura and the neutrophil migration into carrageenan-stimulated mouse air pouches based on the histopathological changes in the paw tissues. Administration of alloferon-1 also suppressed the expression of the inflammatory cytokines in the inflamed paw tissues such as tumor necrosis factor-α (TNF-α), monocyte chemoattractant protein 1 (MCP1), interleukin-5 (IL-5), etc. detected by Luminex liquid chip. Collectively, the present study provides evidences for the marked anti-inflammatory effects of alloferon-1 which might represent new therapeutic options for the treatment of acute inflammatory diseases.

Review
Cardiac magnetic resonance (CMR) provides a high signal-to-noise ratio, high spatial and temporal resolutions, as well as a delayed-enhancement sequence and is therefore considered a reference technique in the field of cardiac imaging. However, currently available sequences are not adequate to assess some pathologic conditions, such as myocardial edema. T2 mapping sequences generate parametric images that are based on the transverse relaxation time (T2) for each voxel. In case of edema, the T2 relaxation time is longer. This review summarizes current knowledge on CMR T2 mapping for assessing myocardial edema.
