Although PCLD in patients with PCLD is characterized by larger and greater number of hepatic cysts, the clinical course is relatively benign compared with ADPKD.
This is the first detailed report on pregnancy and delivery of two babies after maternal treatment of MS with natalizumab. From the small number of cases on the usage of natalizumab during pregnancy in literature, we cannot conclude whether the use of natalizumab is safe, and long-term effects are not known. Further research is needed to establish the exact effects on pregnancy and intrauterine development as well as the long-term effects. Prenatal counseling with thorough explanation of the risks and careful decision making is advisable.
BackgroundGynecomastia is defined as the presence of excessive breast tissue in males, which can appear unilateral or bilateral. Bilateral gynecomastia is frequently found in the neonatal period, early in puberty, and with increasing age. Prepubertal unilateral gynecomastia in the absence of endocrine abnormalities is extremely rare, with only a few cases in literature.MethodsWe report the cases of two otherwise healthy boys of 8 and 11 years old with unilateral breast masses. No abnormalities were found on ultrasonography and all endocrine parameters were within normal limits. Treatment consisted of peripheral liposuction followed by subcutaneous partial resection of the gland, conducted through an infra-areolar incision.ResultsMicroscopy of the subcutaneous mastectomy specimen revealed gynecomastia without signs of malignancy. Postoperative course of both patients was uncomplicated, with no signs of recurrence of breast tissue.ConclusionsAtypical presentations of gynecomastia are often not recognized, with little attention to breast development in prepubertal non-obese children. Since prepubertal gynecomastia could be a sign of possible underlying diseases, a thorough examination and further research is recommended. If there is no causal treatment, surgical resection is the therapy of first choice. Peripheral liposuction and surgical resection of the gland tissue are the mainstay of treatment. In summary, we describe two cases of prepubertal unilateral gynecomastia with a normal endocrine workup. Further research is needed to establish the pathophysiologic mechanisms of prepubertal gynecomastia, since underlying etiology in most cases remains unclear.
BackgroundAcral overgrowth is a highly common clinical sign in patients with active acromegaly. To what extent this overgrowth persists after long-term remission of acromegaly is largely unknown. Using the new imaging technique of three-dimensional (3D) stereophotogrammetry, it is possible to accurately investigate soft tissue changes of the hand. The aim of the recent study was to compare the 3D soft tissue characteristics of the hands of patients in long-term remission of acromegaly to those of a healthy pair matched control group.MethodsA case-control study was performed at a tertiary referral center. Twelve patients in remission of acromegaly (58 % male, mean age 58.3 years, mean BMI 29.6 kg/m2) were compared to twelve age-, gender-, ethnicity-, and BMI-matched control subjects. Of each individual, 3D photographs of both hands were acquired and analyzed using a 3D computer software program.ResultsThe patients in long-term remission of acromegaly have overgrowth of soft tissue of the hand compared to matched control subjects, with a larger length and width of the hand (p = 0.0025, p = 0.0017, respectively). Furthermore, the diameters measured at the proximal interphalangeal (PIP) joints of the individual fingers are larger in the acromegaly patients.ConclusionsSignificant soft tissue overgrowth of the hand persists in former acromegaly patients, even after long-term remission. Analysis of 3D hand photographs is an accurate and easy tool to evaluate the acral soft tissue patterns in acromegaly.Level of Evidence: Level III, diagnostic study.
PurposeUsing three-dimensional (3D) stereophotogrammetry precise images and reconstructions of the human body can be produced. Over the last few years, this technique is mainly being developed in the field of maxillofacial reconstructive surgery, creating fusion images with computed tomography (CT) data for precise planning and prediction of treatment outcome. Though, in hand surgery 3D stereophotogrammetry is not yet being used in clinical settings.MethodsA total of 34 three-dimensional hand photographs were analyzed to investigate the reproducibility. For every individual, 3D photographs were captured at two different time points (baseline T0 and one week later T1). Using two different registration methods, the reproducibility of the methods was analyzed. Furthermore, the differences between 3D photos of men and women were compared in a distance map as a first clinical pilot testing our registration method.ResultsThe absolute mean registration error for the complete hand was 1.46 mm. This reduced to an error of 0.56 mm isolating the region to the palm of the hand. When comparing hands of both sexes, it was seen that the male hand was larger (broader base and longer fingers) than the female hand.ConclusionsThis study shows that 3D stereophotogrammetry can produce reproducible images of the hand without harmful side effects for the patient, so proving to be a reliable method for soft tissue analysis. Its potential use in everyday practice of hand surgery needs to be further explored.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
