RESUMO

ABSTRACT: Endometriosis is a benign condition of the female genital system, characterized by endometrial tissue external to the uterine cavity. Of all cases with endometriosis, the incidence of umbilical endometriosis is only 0.29%. Umbilical endometriosis typical presents with symptoms including cyclical pain, bleeding, and swelling of the nodule. Morphological changes in the epidermis, as in this case, simulating a seborrheic keratosis both clinically and microscopically, can initially mask the underlying endometriosis and prolong the course of treatment. A thorough anamnesis and examination revealing the characteristic symptoms and findings coupled with a representative biopsy is essential to correctly diagnose umbilical endometriosis.

RESUMO

Intramuscular injections of paraffin oil can cause foreign body granuloma formation and hypercalcemia. Macrophages with the ability to produce high levels of 1,25(OH)2 D3 may induce the mineral disturbance, but no major series of patients have been published to date. Here, medical history, physical evaluation, biochemical, and urinary analysis for calcium homeostasis were obtained from 88 males, who 6 years previously had injected paraffin or synthol oil into skeletal muscle. Moreover, granuloma tissue from three men was cultured for 48 hours ex vivo to determine 1,25(OH)2 D3 production supported by qPCR and immunohistochemistry of vitamin D metabolism and immune cell populations after treatment with 14 different drugs. The 88 men were stratified into men with hypercalcemia (34%), whereas normocalcemic men were separated into men with either normal (42%) or suppressed parathyroid hormone (PTH) (24%). All men had high calcium excretion, and nephrolithiasis was found in 48% of hypercalcemic men, 22% of normocalcemic men with normal PTH, and 47% of normocalcemic men with suppressed PTH. Risk factors for developing hypercalcemia were oil volume injected, injection of heated oil, high serum interleukin-2 receptor levels, and high urine calcium. High 1,25(OH)2 D3 /25OHD ratio, calcium excretion, and low PTH was associated with nephrolithiasis. The vitamin D activating enzyme CYP27B1 was markedly expressed in granuloma tissue, and 1,25(OH)2 D3 was released in concentrations corresponding to 40% to 50% of the production by human kidney specimens. Dexamethasone, ketoconazole, and ciclosporin significantly suppressed granulomatous production of 1,25(OH)2 D3 . In conclusion, this study shows that injection of large oil volumes alters calcium homeostasis and increases the risk of nephrolithiasis. Hypercalciuria is an early sign of disease, and high granulomatous 1,25(OH)2 D3 production is part of the cause. Prospective clinical trials are needed to determine if ciclosporin, ketoconazole, or other drugs can be used as prednisolone-sparing treatment. © 2020 American Society for Bone and Mineral Research (ASBMR).

RESUMO

We have described subcutaneous encapsulated fat necrosis, which is benign, usually asymptomatic and underreported. Images have only been published on two earlier occasions, in which the necrotic nodules appear "pearly" than the cloudy yellow surface in present case. The presented image may help future surgeons to establish the diagnosis peroperatively.

RESUMO

Obesity is a strong risk factor for hypertension, but the mechanism linking obesity to hypertension is not fully elucidated. In obesity, circulating concentrations of adiponectin are decreased and hypoadiponectinaemia has in some but not all studies been associated with increased risk of hypertension. Due to this inconsistency, we decided to study adiponectin from two aspects in a cross-sectional in vivo study and in an experimental in vitro study. In the cross-sectional study, 103 men with body mass index (BMI) ≥ 30.0 kg/m(2) were studied; 63 had 24-hr ambulatory blood pressure (ABP) ≥ 130/80 mmHg (ObeseHT) and 40 had 24-hr ABP < 130/80 mmHg (ObeseNT). As controls, we studied 27 men with BMI between 20.0 and 24.9 kg/m(2) and 24-hr ABP < 130/80 mmHg (LeanNT). Serum concentrations of adiponectin and body composition using dual-energy X-ray absorptiometry scanning were determined. In vitro, the direct vasomotor response of adiponectin was tested on subcutaneous resistance arteries from human abdominal adipose tissue. The two obese groups had lower adiponectin concentrations compared with LeanNT (p < 0.01) [median (interquartile range)]: ObeseHT 6.5 (5.1-8.3) mg/L; ObeseNT 6.6 (5.2-7.8) mg/L; and LeanNT 9.4 (6.7-12.4) mg/L, with no significant difference in adiponectin concentrations (or body composition) between ObeseHT and ObeseNT (p = 0.67). In vitro, adiponectin did not have any direct vasodilatory effect and adiponectin did not affect angiotensin II-stimulated vasoconstriction. In conclusion, obese hypertensive men have similar serum concentrations of adiponectin as obese normotensive men. In combination with the in vitro data, these findings question a pathogenic role of adiponectin in human hypertension.

RESUMO

A large aterior chest wall defect following tumor resection was reconstructed with a Gore-Tex® membrane and a combined musculocutaneous rectus femoris and tensor fasciae latae free flap. Subsequent paradoxical respiration impeded weaning from the ventilator. Appliance of Vacuum Assisted Closure® (VAC®) resulted in immediate chest wall stability and a decrease in the patient's need for respiratory support. Shortly thereafter, the VAC® was discontinued and the patient was discharged from the intensive care unit (ICU). This case report is the first to describe the successful use of VAC® as an adjuvant to a one-stage procedure for large thoracic wall reconstruction, allowing sufficient temporary external fixation to eliminate paradoxical respiration and plausibly shorten the stay in the ICU. No adverse effects on flap healing or haemodynamics were recorded. It is likely that external VAC® can improve thoracic stability and pulmonary function in a patient with flail chest and decrease the need for mechanical ventilation.

RESUMO

If a tissue biopsy from a chronic wound is sampled for culture, the antibacterial properties of local anesthetics may pose a problem in producing false-negative results. The purpose of this study was to investigate the effects of EMLA (AstraZeneca) and lidocaine on common wound pathogenic bacteria. An in vitro study of a total of 25 clinical isolates and ATCC reference strains of Staphylococcus aureus (including methicillin-resistant S. aureus), Escherichia coli, Pseudomonas aeruginosa, and Streptococcus pyogenes was conducted. The isolates were exposed to the local anesthetic drugs (and some of their contents separately) at 35 degrees C over a 24-hour period and time-kill curves were recorded. No culture media were used and saline was used for controls. EMLA was found to have a rapid acting and powerful antibacterial effect and should not be used before culturing tissue samples. Lidocaine 1% was found not to inhibit the bacterial strains when exposure time was held below 2 hours. We conclude that culturing tissue from a wound biopsy is safe within 2 hours when a pure, preservative-free lidocaine 1% solution is used.
