The role of liquid-based cytology and ancillary techniques in pleural and pericardic effusions: An institutional experience

BACKGROUND: Fine-needle aspiration cytology (FNAC) of serous membrane effusions may fulfil a challenging role in the diagnostic analysis of both primary and metastatic disease. From this perspective, liquid-based cytology (LBC) represents a feasible and reliable method for empowering the performance of ancillary techniques (ie, immunocytochemistry and molecular testing) with high diagnostic accuracy. METHODS: In total, 3171 LBC pleural and pericardic effusions were appraised between January 2000 and December 2013. They were classified as negative for malignancy (NM), suspicious for malignancy (SM), or positive for malignancy (PM). RESULTS: The cytologic diagnoses included 2721 NM effusions (2505 pleural and 216 pericardic), 104 SM effusions (93 pleural and 11 pericardic), and 346 PM effusions (321 pleural and 25 pericardic). The malignant pleural series included 76 unknown malignancies (36 SM and 40 PM effusions), 174 metastatic lesions (85 SM and 89 PM effusions), 14 lymphomas (3 SM and 11 PM effusions), 16 mesotheliomas (5 SM and 11 SM effusions), and 3 myelomas (all SM effusions). The malignant pericardic category included 20 unknown malignancies (5 SM and 15 PM effusions), 15 metastatic lesions (1 SM and 14 PM effusions), and 1 lymphoma (1 PM effusion). There were 411 conclusive immunocytochemical analyses and 47 molecular analyses, and the authors documented 88% sensitivity, 100% specificity, 98% diagnostic accuracy, 98% negative predictive value, and 100% positive predictive value for FNAC. CONCLUSIONS: FNAC represents a primary diagnostic tool for effusions and a reliable approach with which to determine the correct follow-up. Furthermore, LBC is useful for ancillary techniques, such as immunocytochemistry and molecular analysis, with feasible diagnostic and predictive utility.

Retinal Detachment in Preeclampsia

Preeclampsia is an obstetric disease of unknown cause that affects approximately 5% of pregnant women. The visual system may be affected with variable intensity, being the retinal detachment a rare complication. The retinal detachment in preeclampsia is usually bilateral and serous, and its pathogenesis is related to the choroidal ischemia secondary to an intense arteriolar vasospasm. The majority of patients have complete recovery of vision with clinical management, and surgery is unnecessary. This is a case report of a 27 year old patient who developed the severe form of preeclampsia on her first pregnancy. She had progressive blurred vision, until she could see only shadows. Ophthalmic examination diagnosed spread and bilateral retinal detachment. With blood pressure control at postpartum, the patient had her retina reattached, and recovery of vision.

Estudos sobre thrombose cardiaca e endocardite parietal de origem não valvular

1.-Since the parietal endocarditis represents a chapter generally neglected, owing to the relative lack of cases, and somewhat confused because there various terms have been applied to a very same morbid condition, it justifies the work which previously we tried to accomplish, of nosographic classification. Taking into account the functional disturbances and the anatomical changes, all cases of parietal endocarditis referred to in the litterature were distributed by the following groups: A-Group-Valvulo-parietal endocarditis. 1st . type-Valvulo-parietal endocarditis per continuum. 2nd. type-Metastatic valvulo-parietal endocarditis. 3rd. type-Valvulo-parietal endocarditis of the mitral stenosis. B-Group-Genuine parietal endocarditis. a) with primary lesions in the myocardium. b) with primary lesions in the endocardium. 4th type-Fibrous chronic parietal endocarditis (B A Ü M L E R), « endocarditis parietalis simplex». 5th type-Septic acute parietal endocarditis (LESCHKE), «endocarditis parietalis septica». 6th type-Subacute parietal endocarditis (MAGARINOS TORRES), «endocarditis muralis lenta». 2.-Studying a group of 14 cases of fibrous endomyocarditis with formation of thrombi, and carrying together pathological and bacteriological examinations it has been found that some of such cases represent an infectious parietal endocarditis, sometimes post-puerperal, of subacute or slow course, the endocardic vegetations being contamined by pathogenic microörganisms of which the most frequent is the Diplococcus pneumoniae, in most cases of attenuated virulence. Along with the infectious parietal endocarditis, there occur arterial and venous thromboses (abdominal aorta, common illiac and femural arteries and external jugular veins). The case 5,120 is a typical one of this condition which we name subacute parietal endocarditis (endocarditis parietalis s. muralis lenta). 3.-The endocarditis muralis lenta encloses an affection reputed to be of rare occurrence, the «myocardite subaigüe primitive», of which JOSSERAND and GALLAVARDIN published in 1901 the first cases, and ROQUE and LEVY, another, in 1914. The «myocardite subaigüe primitive» was, wrongly, in our opinion, included by WALZER in the syndrome of myocardia of LAUBRY and WALZER, considering that, in the refered cases of JOSSERAND and GALLAVARDIN and in that of ROQUE and LEVY, there are described rather considerable inflammatory changes in the myocardium and endocardium. The designation «myocardia» was however especially created by LAUBRY and WALZER for the cases of heart failure in which the most careful aetiologic inquiries and the most minucious clinical examination were unable to explain, and in which, yet, the post-mortem examination did not reveal any anatomical change at all, it being forcible to admit, then, a primary functional change of the cardiac muscle fibre. This special cardiac condition is thoroughly exemplified in the observation that WALZER reproduces on pages 1 to 7 of his book. 4.-The clinical picture of the subacute parietal endocarditis is that of heart failure with oedemas, effusion in the serous cavities and passive chronic congestion of the lungs, liver, kideys and spleen associated, to that of an infectious disease of subacute course. The fever is rather transient oscillating around 99.5 F., being intersected with apyretic periods of irregular duration; it is not dependent on any evident extracardiac septic infection. In other cases the fever is slight, particularly in the final stage of the disease, when the heart failure is well established. The rule is to observe then, hypothermy. The cardiac-vascular signs consist of enlargement of the cardiac dullness, smoothing of the cardiac sounds, absence of organic murmurs and accentuated and persistent tachycardia up to a certain point independent of fever. The galloprhythm is present, in most cases. The signs of the pulmonary infarct are rather expressed by the aspect of the sputum, which is foamy and blood-streaked than by the classic signs. Cerebral embolism was a terminal accident on various cases. Yet, in some of them, along with the signs of septicemia and of cardiac insufficiency, occurred vascular, arterial (abdominal aorta, common illiac and femurals arteries) and venous (extern jugular veins) thromboses. 5. The autopsy revealed an inflammatory process located on the parietal endocardium, accompanied by abundant formation of ancient and recent thrombi, being the apex of the left ventricle, the junction of the anterior wall of the same ventricle, with the interventricular septum, and the right auricular appendage, the usual seats of the inflammatory changes. The region of the left branch of HIS’ bundle is spared. The other changes found consist of fibrosis of the myocardium (healed infarcts and circumscribed interstitial myocarditis), of recent visceral infarcts chiefly in lungs, spleen and brain, of recent or old infarcts in the kidneys (embolic nephrocirrhosis) and in the spleen, and of vascular thromboses (abdominal aorta, common illiacs and femurals arteries and external jugular veins), aside from hydrothorax, hydroperitoneum, cutaneous oedema, chronic passive congestion of the liver, lungs, spleen and kidneys and slight ictericia. 6. In the subacute parietal endocarditis the primary lesions sometimes locate themselves at the myocardium, depending on the ischemic necrosis associated to the arteriosclerosis of the coronariae arteries, or on an specific myocarditis. Other times, the absence of these conditions is suggestive of a primary attack to the parietal endocardium which is then the primary seat of the lesions. It matters little whatever may be the initial pathogenic mechanism; once injured the parietal endocardium and there being settled the infectious injury, the endocarditis develops with peculiar clinical and anatomical characters of remarkable uniformity, constituting an anatomo-clinical syndrome. 7.-The histologic sections show that recent lesions…

Miocardite na forma aguda da doença de Chagas

The autopsy of a case of CHAGAS'S disease or American tryponosomiasis (a girl, 5 years old), dead in the 22nd day of illness is reported. The anatomic diagnosis was a follows: Acute diffuse chagasic nyocarditis. Chagasic encephalitis. Chagasic lymphadenitis of the right posterior auricular node. Tuberculosis of the bronchial and pulmonary nodes. Chronic passive hyperemia and atelectasia of the lungs. Chronic passive congestion and hemorrhages of the spleen. Serous hepatitis. Parotiditis. Edema of the right eyelids. Bilateral hydrothorax. Hydropericardium. Hydroperitoneum. The morphology of Schizotrypanum cruzi in the myocardium is considered. Besides agglomerates with typical small oval or round intracellular bodies, pre-flagellate and flagellate organisms, others are found in which the great amount of parasites and marked pressure exerted by them against each other render very difficult their identification; sometimes the similitude of such agglamerates to Toxoplasma is striking (Fig. 1 and 1 A). In such a case, the structure of the blepharoplast (Fig. 1 and IA), usually preserved, is profitable and allows the identification of the pre-flagellate and flagellate forms of Schizotrypanum cruzi. Most of the small sensitive nerves in the epicardium shows mononuclear infiltration of the perineurium (perineuritis, Figs. 12-14). Microscopically there is extensive Zenker's degeneration (Figs. 6-8) and parasitism of the heart muscle fibers, marked cellular infiltration of the interstitial connective tissue, which are found in the ordinary musculature of every chamber of the heart (Figs. 10-11) as well as in Tawara's node (Fig. 9), main bundle (Fig. 2) and right (Fig. 4) and left (Fig. 5) septal divisions of the bundle of His, and perineuritis. Those anatomic changes are associated to an abnormal electrocardiogram presenting some similitude to that of an anemic infarct of the anterior wall of the heart and which will be discussed elsewhere (unpublished paper by Dias, Nobrega & Laranja).

Autofluorescence Findings Of A Novel Maculopathy In Patient With Spinocerebellar Ataxia Type 1 And Of A Cone - Rod Type Retinal Dysfunction In Three Generation Family With Spinocerebellar Ataxia Type 7

Purpose: To report a novel maculopathy in a patient with SCA1. To describe autofluorescence findings in family with SCA7 and associated cone-rod retinal dysfunction.Methods: 4 affected patients from two families were assessed to investigate a progressive loss of visual acuity (VA). Examinations included fundus photography, autofluorescence (AF) fundus fluorescein angiogragraphy (FFA) and optical coherence tomography. Electroretinogram (full-field) was performed in 2 affected patients. All patients had color vision testing using Ishihara pseudoisochromatic plates. Molecular analysis was performed in family 2.Results: The patient with known diagnosis of SCA1 had a visual acuity of 20/200 bilaterally and dyschromatopsia. He had saccadic pursuit. Fundus examination showed mild retinal pigment epithelium (RPE) changes at the macula. OCT showed bilateral macular serous detachment, which was not obvious at the FFA and explained his VA. AF imaging showed a central hyperfluorescence. The 45 year old proband from family 2 had a visual acuity of 200/20 and dyschromatopsia. ERG testing showed cone type dysfunction of photoreceptors. Her daughter affected at a younger age had the same ERGs findings. Fundus examination showed mild RPE changes in proband, normal findings in her daughter. AF imaging of both patients showed a ring of high density AF around the fovea. The ring was also obvious on near infrared AF. Later onset of gait imbalance led to the diagnosis of SCA7Conclusions: Within the group of spinocerebellar ataxias, only the type 7 is associated with retinal dysfunction. We present the first report of maculopathy associated with SCA1 causing severe vision loss. The ring of high density AF in SCA7 confirmed an early retinal photoreceptor dysfunction in patient with normal fundus.

Bilateral uveal pigmented alterations with remarkable evolution: long term follow-up in a case of possible bilateral diffuse uveal melanocytic proliferation

Purpose: to describe a case of probable bilateral diffuse uveal melanocytic proliferation (BDUMP) with scleral involvement, free from systemic malignancies and cataract. Methods: fifty months of follow up with recurrent complete ophthalmological examinations, including fundus photography, fluorescein/indocyanine green angiography (FA) and optical coherence tomography (OCT). Investigations also included an electroretinography (ERG) and histological examination of scleral biopsy. Extraocular malignancies were repeatedly searched. Results: the patient was a 61 year-old Italian man with chronic hepatitis type C. At first visit his best corrected visual acuity (BCVA) was 20/32 in OS and 20/25 in OD. Funduscopy showed multiple patch-shaped pigmented alterations involving macular region and mid retinal periphery. FA showed corresponding areas of late-phase hyperfluorescent pinpoints (figure 1a, OS) and intemediate-phase hypocyanescence (figure 1b, OS), with subtle serous neurosensory retinal detachment confirmed by OCT. Photopic and scotopic ERG tested normal. Systemic prednisone was administered for one month without any improvement. After ten months round pigmentary lesions appeared also in superior scleral surface of both eyes. Biopsy allowed to disclose slightly pigmented spindle cells. BCVA worsened for further 10 months, with enlargement of FA alteration areas but lenses still clear. After 30 months spontaneous coalescence and atrophy of retinal lesions started, paralleled by progressive visual recovery. At the end of our follow up BCVA was 20/25 in OU while scleral pigmentary lesions remained unchanged. Conclusions: we report the case of a patient with main features of BDUMP and some unusual findings. Although not all classical diagnostic criteria were fulfilled, the presence of scleral pigmented lesions and spontaneous visual recovery may enlarge clinical spectrum of the disease.

Role of vitreoretinal surgery in maximizing treatment outcome following complications after proton therapy for uveal melanoma.

PURPOSE: To assess the role of vitreoretinal surgery in maximizing treatment outcome following complications after proton therapy for uveal melanoma and to evaluate its safety. METHODS: Retrospective chart study on 21 patients (2% of a total of 1,005 treated by proton therapy between January 2003 and August 2007) who had developed a complication requiring vitreoretinal surgery. Mean/median total follow-up after irradiation was 43/43 months (range, 12-70 months). RESULTS: Indications for surgery included vitreous hemorrhage (n = 13), epimacular membrane (n = 5), rhegmatogenous retinal detachment (n = 1), combined vitreous hemorrhage with total serous retinal detachment (n = 1), and vitritis (n = 1). Mean/median interval for vitreoretinal surgery after irradiation was 21/20 months (range, 4-45 months), and mean/median follow-up after pars plana vitrectomy was 22/23 months (range, 2-56 months). Pars plana vitrectomy was combined with retinal photocoagulation (n = 5), air/gas (n = 5), or silicone oil tamponade (n = 1). Mean Snellen visual acuity was 20/200 (0-20/40) before and 20/100 (0-20/25) after pars plana vitrectomy. A transient postoperative rise in intraocular pressure was measured in seven patients. Four patients developed phthisis bulbi. CONCLUSION: Vitreoretinal surgery was efficient in maximizing treatment outcome after proton therapy, as it allowed a better oncologic follow-up. Pars plana vitrectomy permitted panretinal photocoagulation to avoid neovascular glaucoma or retinal detachment repair. Macular surgery improved visual acuity, especially in anterior melanoma, whereas repeated surgery may increase the risk of enucleation.

Mineralocorticoid receptor is involved in rat and human ocular chorioretinopathy.

Central serous chorioretinopathy (CSCR) is a vision-threatening eye disease with no validated treatment and unknown pathogeny. In CSCR, dilation and leakage of choroid vessels underneath the retina cause subretinal fluid accumulation and retinal detachment. Because glucocorticoids induce and aggravate CSCR and are known to bind to the mineralocorticoid receptor (MR), CSCR may be related to inappropriate MR activation. Our aim was to assess the effect of MR activation on rat choroidal vasculature and translate the results to CSCR patients. Intravitreous injection of the glucocorticoid corticosterone in rat eyes induced choroidal enlargement. Aldosterone, a specific MR activator, elicited the same effect, producing choroid vessel dilation -and leakage. We identified an underlying mechanism of this effect: aldosterone upregulated the endothelial vasodilatory K channel KCa2.3. Its blockade prevented aldosterone-induced thickening. To translate these findings, we treated 2 patients with chronic nonresolved CSCR with oral eplerenone, a specific MR antagonist, for 5 weeks, and observed impressive and rapid resolution of retinal detachment and choroidal vasodilation as well as improved visual acuity. The benefit was maintained 5 months after eplerenone withdrawal. Our results identify MR signaling as a pathway controlling choroidal vascular bed relaxation and provide a pathogenic link with human CSCR, which suggests that blockade of MR could be used therapeutically to reverse choroid vasculopathy.

Resolution of foveal detachment in dome-shaped macula after treatment by spironolactone: report of two cases and mini-review of the literature.

Dome-shaped macula (DSM) was recently described in myopic patients as a convex protrusion of the macula within a posterior pole staphyloma. The pathogenesis of DSM and the development of associated serous foveal detachment (SFD) remain unclear. The obstruction of choroidal outflow and compressive changes of choroidal capillaries have been proposed as causative factors. In this paper, we report two cases of patients with chronic SFD associated with DSM treated with oral spironolactone. After treatment, there was a complete resolution of SFD in both patients. To the best of our knowledge, this is the first report of successful treatment of SFD in DSM by a mineralocorticoid receptor antagonist.

PACHYCHOROID: an inherited condition?

PURPOSE: Thick choroid (pachychoroid) is associated with central serous chorioretinopathy (CSC), but whether pachychoroid is inherited is unknown. METHODS: In a prospective observational study, first- or second-degree relatives (16 individuals) of 5 patients with CSC had refraction and visual acuity measurement, fundus examination, nonmydriatic photography, and autofluorescence photography. Eyes were graded using the following criteria: 0: normal fundus and autofluorescence photography, 1: focal retinal pigment epithelium hyperfluorescence and/or hypofluorescence and/or retinal pigment epithelial detachment, 2: CSC or diffuse retinal epitheliopathy. Choroid thickness was measured by enhanced depth imaging mode on optical coherence tomography. RESULTS: Considering 395 μm as the threshold limit for normal subfoveal choroidal thickness, 50% of the eyes from relatives had a thick choroid. Nine eyes of Grade 0 (28%) with an isolated pachychoroid would thus have been considered normal, if choroidal thickness was not included as a screening sign predisposing for CSC. CONCLUSION: Our observation suggests that pachychoroid could be an inherited condition with potentially a dominant transmission mode. Its inclusion in the phenotype of CSC for genetic studies should be considered.

Bilateral Uveal Pigmented Alterations With Remarkable Evolution: Long Term Follow-Up in a Case of Possible Bilateral Diffuse Uveal Melanocytic Proliferation

Purpose: to describe a case of probable bilateral diffuse uveal melanocytic proliferation (BDUMP) with scleral involvement, free from systemic malignancies and cataract.

Peculiar findings in a case of bilateral uveal pigmented lesions.

PURPOSE: To describe a probable case of bilateral diffuse uveal melanocytic proliferation (BDUMP) with unusual manifestations and prognosis. DESIGN: Case report. METHODS: Clinical follow-up of the patient lasting 50 months with recurrent fundus examination using color photographs, angiography, ultrasound, and optical coherence tomography. Serological and radiological investigations were performed to assess possible extraocular alterations. RESULTS: In both eyes patch-shaped pigmented alterations of the fundus were revealed. Fluorescein and indocyanine angiography evidenced corresponding areas of hyperfluorescent pinpoints and subtle serous detachment of the neurosensory retina, respectively. Ten months after the initial evaluation, flat pigmentary lesions appeared in the superior scleral surface of the right eye and underwent histological examination. After an initial decrease in visual acuity, the patient experienced a spontaneous recovery. He did not develop cataracts or any systemic malignancies. CONCLUSIONS: Although not all the criteria for the diagnosis were fulfilled, clinical findings were compatible with BDUMP. The presence of scleral pigmented lesions and the good visual prognosis may widen the spectrum of this rare disease.

Morgagnian cataract simulating iris neoplasia : case report

Purpose: to describe a case in which the diagnosis of Morganian cataract required clinical and instrumental differentiation from iris pathologies, including iris melanoma. Methods: a 60-years-old Caucasian man referred to our institute for worsening of vision in last few months. Clinical evaluation consisted in complete ophthalmological assessment, ultrasound examination (biomicroscopy and 20MHz), and Magnetic Resonance Imaging (MRI) completed with Susceptibility Weighted Imaging (SWI). Results: traumatic corneal wound of the left eye (LE) had occurred 5 years before, and was treated with medical therapy alone. Best-corrected visual acuity (BCVA) was 3/10 in the right eye (RE) and finger count in the LE, with intraocular pressure at 13 and 20mmHg, respectively. Chronic central serous chorioretinopathy, accounted for the low visual acuity of the RE. Slit-lamp biomicroscopy of the LE was as in Figure 1; LE fundus was not clinically observable. Despite MRI was compatible with an iris solid formation, characterized by contrast enhancement and hyperintense signal in SWI, ultrasound indicated rather a mixed solid and liquid content (moderately echogenic external layer, hyporeflective internal content). Iris root and ciliary body were not significantly altered; the lens showed inhomogeneous content. We considered Morgagnian cataract the most probable diagnosis. Surgery confirmed the presence of a hypermature cataract with prior anterior capsule fissuring; the liquefied cortex infiltrated the iris without anterior chamber seeping. Post-operative BCVA was 3/10 and fundus examination disclosed an advanced macular chronic central serous chorioretinopathy. Conclusions: In the reported case a previous perforating trauma have probably damaged the lens capsule and started cataract progression. Curiously cataract developed percolating into the iris stroma, thus simulating an iris mass. At our knowledge, Morgagnian cataract has never been included in the differential diagnosis of iris mass.

Apport de l'angiographie au vert d'indocyanine (ICG) dans la localisation des néovascularisations chororoidiennes occultes [Value of indocyanine green angiography in localization of occult choroid neovascularization]

PURPOSE: To determine the role of Indocyanin Green (ICG) angiography in localizing occult new vessels associated with age-related macular degeneration (ARMD) and assess the possibilities of ICG guided laser photocoagulations. PATIENTS AND METHODS: Fluorescein and ICG angiographies (IMAGEnet system) of 62 patients with occult new vessels (ONV), serous (SPED) or vascular (VPED) pigment epithelium detachment have been studied. RESULTS: Based on fondoscopic examination and fluorescein angiography, 43 eyes (69%) disclosed ONV, 8 (13%) SPED and 11 (18%) VPED. Choroidal neovascularisation was confirmed by ICG angiography in 37 ONV cases (86%), in 8 (72%) VPED cases, but in no SPED. Conversion of ONV in classical neovascular membranes was possible in 19 ONV cases (44%) and in 6 (54%) VPED cases, making a laser photocoagulation possible in 9 eyes (36%). CONCLUSION: ICG angiography plays an important role in the evaluation, classification and laser treatment of patients with ONV secondary to ARMD.
