Papillary carcinoma arising in struma ovarii versus ovarian metastasis from primary thyroid carcinoma: a case report and review of the literature
We present a case of a postmenopausal woman diagnosed with an ovarian mass containing thyroid follicles and foci of papillary thyroid carcinoma during pathological examination. This patient referred having had a metachronous thyroid malignancy 10 years before. The differential diagnosis between a thyroid malignancy arising from a struma ovarii and a metastatic ovarian tumor originating from thyroid-cancer is challenging. Struma ovarii should be considered when thyroid components are the predominant element or when thyroid malignant tissue is identified within an ovarian lesion. Thyroid carcinoma arising from a struma ovarii is reported to occur in a minority of cases. Of these, papillary carcinoma is the most frequent subtype encountered. Regarding primary thyroid carcinomas, papillary carcinomas have a lower metastatic potential when compared to follicular carcinomas, and most of the metastases occur in the cervical lymph nodes. Ovarian metastases are exceedingly rare and generally associated with widespread disease. However, they must be considered in the presence of previous history of malignant thyroid carcinoma. The authors review the main clinical, imaging and therapeutic aspects of both these entities and present the most likely diagnosis
Consecutive bilateral decompression retinopathy after mitomycin C trabeculectomy: a case report
BACKGROUND:
After a successful trabeculectomy, a sudden intraocular pressure decrease may alter the intracranial to intraocular pressure ratio and cause decompression retinopathy. Frequent Valsalva maneuvers may also play a role in its pathogenesis. This condition may manifest as multiple retinal hemorrhages, edema of the optic disc, macular edema, or a sudden decrease in visual acuity postoperatively. Outcomes for patients are usually good, with spontaneous resolution occurring within a matter of weeks. It has been rarely reported in the literature as a bilateral condition.
CASE PRESENTATION:
We present a case of consecutive bilateral decompression retinopathy in a 54-year-old severely obese Caucasian woman (body mass index 37 kg/m(2)) with open angle glaucoma and a poor history of medical therapeutic compliance, who chose surgical treatment based on her inability to consistently use ocular drops. Our patient underwent a trabeculectomy with mitomycin C in both eyes, with surgeries taking place 3 months apart. After the first surgery, 2 weeks postoperatively, she complained of decreased visual acuity. Examination of her right eye fundus revealed multiple retinal hemorrhages and disc edema. There was a similar pattern in her left eye, this time including maculopathy. Her visual acuity and fundoscopic changes resolved spontaneously over a period of a month in both cases. Currently, our patient has well-controlled bilateral intraocular pressure, ranging between 14 and 16 mmHg, without hypotensive medication.
CONCLUSIONS:
Decompression retinopathy is a potential complication after glaucoma surgery, but has rarely been described as a bilateral consecutive condition. A comprehensive approach could help to anticipate its occurrence and manage it.info:eu-repo/semantics/publishedVersio

[Fetal growth and activity at 20 to 24 weeks of gestation (preliminary study)].
BACKGROUND: Recent researches show that psychological development begins much before birth and prenatal influences can explain a significant part of the future variability in infants' behaviour and development.
AIMS: The aim of this study was to characterize the fetal development between 20 and 24 weeks of gestation, related to the measures of fetal growth-- iparietal diameter, abdominal circumference, head circumference, femur length and fetal weight-- and fetal activity--fetal heart rate and fetal movements. We also tried to establish if there are any differences in these measures related to the mothers' and fetus' sociodemographic features, obstetrical conditions and exposure to drugs.
METHOD: The sample of this study involved 48 fetus (52.1% female and 47.9% male) with an estimated gestational age (GA) between 20-24 weeks (Mean = 21 weeks and 1 day), whose mothers had appointments at the Obstetric and Gynaecological medical consultation of Júlio Dinis Maternity Hospital (MJD, Oporto). A video tape of the fetal behaviour was made and ultrasound biometry measurements were collected from the morphological ultrasound report.
RESULTS: A statistical analysis of fetal data, after gestational age control, showed differences in fetal growth measures related to mothers' occupational status [F(1,41) = 7.28; p = .000], marital status [F(1,41) = 2.61; p = .04], household arrangements [F(1,41) = 2.91; p = .03] and coffee consumption [F(1,40) = 2.55; p = .05]. Differences in fetal activity measures (fetal heart rate) associated to fetus gender [F(1,16) = 5.84; p = .009] were also found.
CONCLUSIONS: We can conclude about the sensibility of fetal development to prenatal factors related to the mothers' and fetus' sociodemographic features and exposure to drugs.Esta investigação foi financiada pela Fundação para a Ciência e a Tecnologia, no âmbito do projecto FCT POCTI/SAUESP,
