Office Hysteroscopy After Ultrasonographic Diagnosis of Thickened Endometrium in Postmenopausal Patients

The aim of our study was to access office hysteroscopy results in postmenopausal patients with thickened endometrium. A retrospective descriptive study was carried out on 245 postmenopausal patients submitted to office hysteroscopy after sonographic diagnosis of thickened endometriumin 20 consecutive months.Women were evaluated for age, hormonal therapy, hysteroscopic findings, procedure duration, complications and associated pain, and histological diagnosis. Patients with and without uterine bleeding were considered separately. Symptomatic patients were older and had longer procedure duration. The most frequent hysteroscopic finding was endometrial polyp in both groups. Pain was subjectively assessed in a numeric scale from 0 to 10 and median value was 4. There were no complications reported. Global neoplasia rate was 2.9% for asymptomatic patients and 16.4% for symptomatic ones (p<0.05). Thickened endometrium with postmenopausal metrorrhagia gave patients a significantly higher risk for neoplasia and hyperplasia.

Anti-Phospholipase A2 Receptor Antibodies in the Diagnosis of Idiopathic Membranous Nephropathy

Circulating anti-phospholipase A2 receptor antibodies (anti-PLA2R) have been described in 70% to 80% of the patients with idiopathic membranous nephropathy (iMN), but not in patients with secondary membranous nephropathy or other glomerular diseases. The goal of this study was to evaluate the sensitivity and specificity of the assay for anti-PLA2R in the diagnosis of iMN. Anti-PLA2R IgG, Elisa and immunofluorescence tests were used to detect circulating anti-PLA2R. These tests were applied in 53 patients who had a kidney biopsy. Of these, 38 had histological diagnosis of membranous nephropathy (MN) and the remaining had other glomerular diseases. The MN was classified as idiopathic in 33 patients after clinical exclusion of secondary causes. Anti-PLA2R were positive in 57.6% of the patients with iMN. All patients with secondary membranous nephropathy or other glomerular diseases did not show circulating anti-PLA2R. The sensitivity was 57.6% (CI 39.2-74.5) and specificity 100% (CI 47.8-100), AUC 0.788; p < 0.0001 for the detection of iMN. 71.4% of the iMN patients that tested negative for anti-PLA2R were in partial or complete remission. The detection of anti-PLA2R in the studied population had a specificity of 100% for the iMN diagnosis. Prior treatments seem to make the test negative and contribute to a lower sensitivity.

Skin Prick Tests and Allergy Diagnosis

Skin testing remains an essential diagnostic tool in modern allergy practice. A signifi cant variability has been reported regarding technical procedures, interpretation of results and documentation. This review has the aim of consolidating methodological recommendations through a critical analysis on past and recent data. This will allow a better understanding on skin prick test (SPT) history; technique; (contra-) indications; interpretation of results; diagnostic pitfalls; adverse reactions; and variability factors.

Púrpura. Manifestação de Amiloidose Sistémica Primária

Primary Systemic Amyloidosis (AL) is the most frequent form of systemic amyloidosis and its morbilility is associated with immunoglobulin light chains deposition in vital organs. The mucocutaneous manifestations occur in about 30-40% of the cases and are important in diagnostic suspicion, once they appear in early stages of disease. We report a 71-years-old female patient, with disseminated purpura and cutaneous fragility with 6 months of evolution, accompanied by recent complaints of dysphagy. The first laboratory evaluation didn't show any alterations. The histological and immunohistochemical study of subcutaneous abdominal fat and skin biopsy showed lambda type amyloid protein. In the systemic work-up, we highlight a proteinúria > 1g/24h with Bence Jones proteins and the presence of monoclonal immunoglobulin light chain (lambda type) in serum immunoelectrophoresis. With the diagnosis of primary systemic amyloidosis, treatment with prednisolone and melphalan was started.

Derrame Pericárdico Recidivante. Um Caso de Angiosarcoma Cardíaco

A case of angiosarcoma of the right atrium in a 59-year-old woman is reported, presenting as a recurrent hematic pericardial effusion. The usefulness of echocardiography in making the diagnosis is emphasized. The tumor was already disseminated at the time of the diagnosis. The patient was on palliative therapy, dying a few months later. The histological examination was done at autopsy. This case highlights the difficulty in diagnosis and the various modalities available for an accurate diagnosis of a rare clinical entity. It has a rapid and aggressive course with a very poor prognosis.

Diabetic Foot Infections: Current Diagnosis and Treatment

Diabetes mellitus (DM) is a global epidemic, and diabetic foot ulcer (DFU) is one of its most serious and costly complications. DFUs result from a complex interaction of a number of risk factors. Once the protective layer of skin is broken, deep tissues are exposed to bacterial infection that progresses rapidly. Patients with DFUs frequently require amputations of the lower limbs and, in more than half the cases, infection is the preponderant factor. Given the challenges of treating these complex infections, this paper aims to provide a hospital-based framework for the diagnosis and treatment of diabetic foot infections (DFIs). We propose a treatment-oriented assessment of DFIs based on a cross-examination of the medical, foot, and wound history; a systemized and detailed physical examination; and the results of complementary diagnostic procedures. We stress the need for a clinical diagnosis of DFIs and the importance of microbiological evaluation for antibiotic therapy guidance. Regarding treatment, we propose a multidisciplinary approach prioritizing invasive infection drainage, necrosis debridement, and the prompt start of empirical antibiotic therapy, followed by complete and appropriate vascular reconstruction. For severe DFIs, we suggest that negative pressure wound therapy (NPWT) be included in the treatment pathway. We also provide rules for managing particular situations, such as osteomyelitis. It is our hope that this protocol will improve the hospital management of DFIs and, ultimately, the prognosis of DFI patients.

Minimal Criteria for the Diagnosis of Avulsion of the Puborectalis Muscle by Tomographic Ultrasound

Introduction and hypothesis Puborectalis avulsion is a likely etiological factor for female pelvic organ prolapse(FPOP). We performed a study to establish minimal sonographic criteria for the diagnosis of avulsion. Methods We analysed datasets of 764 women seen at a urogynecological service. Offline analysis of ultrasound datasets was performed blinded to patient data. Tomographic ultrasound imaging (TUI) was used to diagnose avulsion of the puborectalis muscle. Results Logistic regression modelling of TUI data showed that complete avulsion is best diagnosed by requiring the three central tomographic slices to be abnormal. This finding was obtained in 30% of patients and was associated with symptoms and signs of FPOP (P<0.001). Lesser degrees of trauma (‘partial avulsion’) were not associated with symptoms or signs of pelvic floor dysfunction. Conclusions Complete avulsion of the puborectalis muscle is best diagnosed on TUI by requiring all three central slices to be abnormal. Partial trauma seems of limited clinical relevance.

Appendiceal Mucocele – Unexpected Diagnosis in a Gynecology Department

Appendiceal mucocele is a rare entity, occuring in < 1% among appendicectomies, with a female predominance 4/1 (F/M) and a mean age of more than 50 years. The preoperative diagnosis is difficult; in most cases, it´s an intraoperative finding. In such work, we describe the two clinical cases occurring in last 10 years in our Department. Case 1 - 56 years old, posmenopausal, referred to our Department (02/2004) because an asymptomatic right adnexal septated cystic image, 53x48mm, with hipovascularized septa and a vascularised capsule with low flow resistance (IR 0,57). CA 125 elevated (71,3 U/mL).Exploratory laparotomy: an ovary increased, with a gelatanious consistency and an appendicular enlargement. Extemporaneous examination: a pseudomixoma peritonei, associated with a mucinous appendicular and an ovary tumor. It was performed a radical surgery. The histo-pathological analysis showed a mucinous cystadenoma of the appendix with peritoneal mucinous dissemination involving the ovary. Expectant attitude since the surgery, without clinical and imaging signs of recurrence. Case 2- 62 years old posmenopausal and asymptomatic woman, with a large adnexal mass detected on routine pelvic ultrasound: heterogeneous, 94x84mm without vascularisation signs in its interior. CEA was elevated (41,47U/ml). Exploratory laparotomy (02/2010): enlarged appendix and macroscopically normal pelvic organs. An appendicectomy was performed. The histo-pathological analysis showed a 10cm mucinous cystadenoma of the appendix and signs of localized (visceral peritoneal surface) pseudomyxoma peritonei. Currently she’s clinically well, in an expectant attitude. Despite mucoceles of the appendix are rare, they should be considered in women presenting with abnormal quadrant masses.

McCune Albright Syndrome: A Diagnosis to be Kept in Mind

Precocious puberty, defined as the development of secondary sexual characteristics before the age of 8, often leads to anxiety in patients and their families but also in clinicians searching for the final diagnosis. After adequate investigation, the majority of the cases in girls turn out to be idiopathic. The authors present a case of McCune Albright syndrome in order to call attention to a rare cause of sexual precocity and the value of ultrasound in the evaluation of these situations. 10 years old infant girl admitted in our department due to irregular menstrual bleeding. She experienced a vaginal bleeding by the age of 3 which led to the diagnosis of McCune Albright Syndrome after a complete evaluation. Pubertal assessment revealed a reversed sequence in the remaining events with adrenarche at 5 and thelarche at 8. Hormonal evaluation demonstrated low FSH and LH levels (11,2 and 6,72 respectively) with high estrogen (204). Pelvic ultrasound showed a normal sized uterus (73x 29x32 mm), endometrial thickness of 5 mm and ovaries with several microfollicles and a copus luteum measuring 23 mm in the right ovary. McCune Albright syndrome is a very uncommon cause of sexual precocity that should, however, be suspected in all infant girls who present with vaginal bleeding. It is characterized by a triad: polyostotic fibrous dysplasia, gonadotropin-independent precocious puberty and café-au-lait skin spots. Due to autonomous production of estrogen by the ovaries, ultrasound image of the female reproductive tract is inconsistent with chronologic age. Pelvic ultrasound demonstrates a normal sized uterus with a well defined cervix and clearly identified ovaries with several follicles, similar to adult women of reproductive age. Ultrasonography of the pelvis has also an important role excluding other causes of GnRH-independent precocious puberty conditions like ovarian cysts or tumors.

Case for Diagnosis

Blastic plasmacytoid dendritic cell tumor is a rare, highly aggressive systemic neoplasm for which effective therapies have not yet been established. We describe a 73-year-old man with multiple nodules and patches emerging on the trunk and limbs. Lesional skin biopsy revealed a plasmacytoid dendritic cell tumor with dense dermal infiltrate of tumor cells with blastoid features. No apparent systemic involvement was identified in the initial stage. The patient was treated with prednisone daily, with notorious improvement of the skin lesions, although no complete remission was obtained. During the six-month follow-up period, no disease progression was documented, but fatal systemic progression occurred after that period of time.

Focal Malignant Liver Lesions: Diagnosis by Dynamic Incremental CT, Early Phase

The purpose of our study was to evaluate the accuracy of dynamic incremental bolus-enhanced conventional CT (DICT) with intravenous contrast administration, early phase, in the diagnosis of malignancy of focal liver lesions. A total of 122 lesions were selected in 74 patients considering the following criteria: lesion diameter 10 mm or more, number of lesions less than six per study, except in multiple angiomatosis and the existence of a valid criteria of definitive diagnosis. Lesions were categorized into seven levels of diagnostic confidence of malignancy compared with the definitive diagnosis for acquisition of a receiver-operator-characteristic (ROC) curve analysis and to determine the sensitivity and specificity of the technique. Forty-six and 70 lesions were correctly diagnosed as malignant and benign, respectively; there were 2 false-positive and 4 false-negative diagnoses of malignancy and the sensitivity and specificity obtained were 92 and 97%. The DICT early phase was confirmed as a highly accurate method in the characterization and diagnosis of malignancy of focal liver lesions, requiring an optimal technical performance and judicious analysis of existing semiological data.

Diabetic Mastopathy: a Case Report

Diabetic mastopathy (DMP) is an uncommon collection of clinical, radiological, and histological features, classically described in premenopausal women with long-term insulin-dependent diabetes mellitus. This entity can mimic breast carcinoma, but, in the appropriate clinical and imaging setting, the diagnosis can be made by core biopsy, avoiding unnecessary surgeries. We report the case of a 34-year-old female, with a 12-year history of type 1 diabetes, who presented with bilateral breast lumps. Mammography, ultrasonography, and magnetic resonance imaging could not exclude the suspicion of malignancy, and a core biopsy was performed showing the typical histologic features of DMP. The literature is briefly reviewed.

Case for Diagnosis

A 27 year-old-man, with no known personal or familial history of disease, mentioned a 10-year history of asymptomatic groups of telangiectasias, with a Blaschko lines distribution on the right lateral aspect of the neck and asymptomatic. He denied any episodes of disease or drug intake that could be associated with the disease. Blood work had no changes, namely of liver enzymes or infectious serologies. The clinical diagnosis of Idiopathic Acquired Unilateral Nevoid Telangiectasia was made, an uncommon, benign vascular malformation. The patient declined doing a cutaneous biopsy or treatment with a cosmetic intent.

Transplant Glomerulopathy: Clinico-Pathologic Features

Transplant glomerulopathy is a sign of chronic kidney allograft damage. It has a distinct morphology and is associated with poor allograft survival. We aimed to assess the prevalence and clinic-pathologic features of transplant glomerulopathy, as well as determine the functional and histological implications of its severity. We performed a single-centre retrospective observational study during an eight-year period. Kidney allograft biopsies were diagnosed and scored according to the Banff classification, coupled with immunofluorescence studies. The epidemiology, clinical presentation, outcomes (patient and graft survival) and anti-HLA alloantibodies were evaluated. Transplant glomerulopathy was diagnosed in 60 kidney transplant biopsies performed for clinical reasons in 49 patients with ABO compatible renal transplant and a negative T-cell complement dependent cytotoxicity crossmatch at transplantation. The estimated prevalence of transplant glomerulopathy was 7.4% and its cumulative prevalence increased over time. C4d staining in peritubular capillaries (27.6%) was lower than the frequency of anti-HLA antibodies (72.5%), the majority against both classes I and II. Transplant glomerulopathy was associated with both acute (mainly glomerulitis and peritubular capillaritis) and chronic histologic abnormalities. At diagnosis, 30% had mild, 23.3% moderate and 46.7% severe transplant glomerulopathy. The severity of transplant glomerulopathy was associated with the severity of interstitial fibrosis. Other histological features, as well as clinical manifestations and graft survival, were unrelated to transplant glomerulopathy severity.
