FORMS OF OCULAR LARVAL TOXOCARIASIS IN CHILDHOOD. A REVIEW.

The aim of this paper is to present an outline of forms of ocular manifestations of visceral larva migrans in children, as illustrated by the extensive photographic documentation. Ocular larval toxocariasis (OLT) has various clinical manifestations even in childhood age, in which age representation has an influence. The most common is presence of peripheral granuloma of the eye, frequently with a tractional vitreal streak leading from the retinal periphery to the optic nerve papilla. This is followed by granuloma of the posterior pole of the eye, usually reaching from the macular landscape to the central retinal periphery, always with vitritis. In children OLT may be manifested also in affliction of the optic nerve (cystic granuloma of the head of the optic nerve or neuropathy with vitreal reaction), fulminant endophthalmitis and in rare cases also diffuse chorioretinitis. The diagnosis rests upon a clinical ophthalmological finding, as well as laboratory examination of the levels of antibodies with potential eosinophilia. Histological examination may demonstrate spherical polypoid ossification in the choroid at the posterior pole of the eye as a consequence of fibrotisation and calcification, proceeding from the surrounding area of the absorbed larva. General combined treatment with antihelminthics and corticosteroids is arduous and does not always produce the desired effect in the sense of a satisfactory improvement of visual acuity. In differential diagnostics, manifestations of OLT in small children are still associated with retinoblastoma and a clinical picture of other intraocular diseases.

ATYPICAL FORMS OF EYE TOXOPLASMOSIS IN CHILDHOOD. CASE REPORTS.

AIM: To present an outline of acquired atypical forms of ocular toxoplasmosis (OT) in childhood, with reference to the 100th anniversary of the discovery of this etiology by Professor Janků from Czechoslovakia, who was first to describe the clinical congenital picture of OT characterised by macular scar. MATERIAL AND METHODS: Symptoms of intraocular bilateral neuritis appeared in a 6-year-old girl, with visual acuity (VA) bilaterally 0.1. Toxoplasmic etiology was demonstrated in laboratory tests, and the patient was immunocompetent. Following treatment with macrolide antibiotic and parabulbar application of corticosteroid, the condition was normalised stably at VA 1.0 in both eyes. Bilateral retinal vasculitis was determined in an 8-year-old boy, with VA of 0.25 in the right eye and 0.25 in the left, with a medical history of strabismus detected after suffering from varicella. The examination for toxoplasmosis was negative, but pronounced general hypogammaglobulinaemia classes IgG, IgM and IgA was detected. Immunosuppressive and immunomodulatory therapy did not produce the desired effect, and the condition progressed to retinochoroiditis. Due to blindness and dolorous glaucoma, enucleation of the right eye was performed at the age of 15 years. Histologically toxoplasmic cysts with bradyzoites were detected, a subsequent laboratory test demonstrated toxoplasmic etiology upon a background of persistent regressing hypogammaglobulinaemia. General anti-toxoplasma and subsequent immunosuppressive treatment did not produce the desired effect, and at the age of 22 years the patient lost his sight also in the left eye. CONCLUSION: Atypical form of OT intraocular neuritis in an immunocompetent patient had a favourable course, whereas retinal vasculitis with retinochoroiditis in a temporarily immunocompromised patient ended in bilateral blindness.

BILATERAL AMYLOIDOSIS OF THREE EYELIDS. A CASE REPORT.

AIM: To present rare form of lids amyloidosis, in the context with literature and remind a Czech professor Vrabec, F., MD, an important pan-European ocular histologist. CASE REPORT: 37 years aged man was examined for eyelids mass on the department of ophthalmology of the Teaching Hospital Kralovske Vinohrady, Prague, Czech Republic in June 2018. The finding looked like chronic chalazion on the right side and chronic hordeolum on the left side. No acute phase was noted within last several months by the patient. Yellowish to lightly brown friable, partially transparent mass was obtained by excision. Amyloidosis of the AL type was revealed histologically, and diagnosis was followed by extended excision and plastic surgical reconstruction of the lower eyelids on both sides. No systemic disease underlying the amyloidosis was disclosed by following through diagnostic work-up of the patient. RESULTS: Amyloidosis was illustrated initially by Congo red staining with characteristic dichroism in the polarized light, then it was analysed immunohistochemically, with positivity for kappa light chains. Systemic amyloidosis was excluded, as well as monoclonal gamapathy. Only slightly increased number of plasmacytes (up to 10 %) was revealed in the bone marrow biopsy. The surgical solution was optimal for the patient, and he was without any recurrence and problems of lower eyelids three years. CONCLUSION: Described case of bilateral eyelids amyloidosis without underlying systemic disease belongs to rare cases and also illustrates necessity of complex interdisciplinary cooperation in the diagnostic process.

Folate hydrolase-1 (FOLH1) is a novel target for antibody-based brachytherapy in Merkel cell carcinoma.

BACKGROUNDS: Folate Hydrolase-1 (FOLH1; PSMA) is a type II transmembrane protein, luminally expressed by solid tumour neo-vasculature. Monoclonal antibody (mAb), J591, is a vehicle for mAb-based brachytherapy in FOLH1+ cancers. Brachytherapy is a form of radiotherapy that involves placing a radioactive material a short distance from the target tissue (e.g., on the skin or internally); brachytherapy is commonly accomplished with the use of catheters, needles, metal seeds and antibody or small peptide conjugates. Herein, FOLH1 expression in primary (p) and metastatic (m) Merkel cell carcinoma (MCC) is characterized to determine its targeting potential for J591-brachytherapy. MATERIALS & METHODS: Paraffin sections from pMCC and mMCC were evaluated by immunohistochemistry for FOLH1. Monte Carlo simulation was performed using the physical properties of conjugated radioisotope lutetium-177. Kaplan-Meier survival curves were calculated based on patient outcome data and FOLH1 expression. RESULTS: Eighty-one MCC tumours were evaluated. 67% (54/81) of all cases, 77% (24/31) pMCC and 60% (30/50) mMCC tumours were FOLH1+. Monte Carlo simulation showed highly localized ionizing tracks of electrons emitted from the targeted neo-vessel. 42% (34/81) of patients with FOLH1+/- MCC had available survival data f or analysis. No significant differences in our limited data set were detected based on FOLH1 status (p = 0.4718; p = 0.6470), staining intensity score (p = 0.6966; p = 0.9841) or by grouping staining intensity scores (- and + vs. ++, +++, +++) (p = 0.8022; p = 0.8496) for MCC-specific survival or recurrence free survival, respectively. CONCLUSIONS: We report the first evidence of prevalent FOLH1 expression within MCC-associated neo-vessels, in 60-77% of patients in a large MCC cohort. Given this data, and the need for alternatives to immune therapies it is appropriate to explore the safety and efficacy o f FOLH1-targeted brachytherapy for MCC.

UVEAL MELANOMA IN A 15-YEAR-OLD GIRL. CASE REPORT.

Uveal melanoma is the most common intraocular tumour in adults, it is a form of cancer that affects mostly older adults, as the average age at detection of this tumour is 60 years, but it can occur in any age group with no significant gender difference. However, uveal melanoma is very rare in children compared to the adult population, accounting for 1 % of all cases. In pediatric patients, malignant uveal melanoma is more frequently manifested during puberty, leading to speculation of an association between uveal melanoma and growth hormone levels. Prognostic factors for uveal melanoma include tumour histology, chromosomal abnormalities, tumour size, extrascleral spread and tumour location. Risk factors for uveal melanoma include melanocytosis, neurofibromatosis type 1 and dysplastic naevus syndrome. Some studies point to a significantly lower risk of developing metastases in younger patients, but the prognosis of uveal melanoma in children is not yet fully known. Clinical signs and treatment options for malignant uveal melanoma in children are still under discussion. Differential diagnosis of uveal lesions in children can sometimes be very difficult, as evidenced by following case report in which authors describe a case of choroidal melanoma in a 15-year-old girl.

Merkel Cell Carcinoma of the Eyelids (Clinical-Histological Study).

AIM: To get acquainted with the issues of Merkel cell carcinoma (MCC) when the eyelid is affected and with its surgical solution. MATERIALS: MCC of the right upper eyelid was at the Department of Ophthalmology in the Faculty Hospital Královské Vinohrady in Prague (Czech Republic, EU) in 1998 woman 78 year. Another cases of the MCC on the left upper eyelid were observed in two women aged 48 and 67 years and they were pick up in a retrospective study covered 1033 operated tumors eyelids years 2007 - 2015. 47,5% of operated tumors were benign and 52,5% malignant. Most common malignant processes were basal cell carcinoma in 77,3% and squamous cell carcinoma at 15,7%. RESULTS: The oldest patient died after three years of cardiopulmonary failure. 48 year old patient (age of diagnosis MCC) has been monitoring for five years without proven recurrence or metastasis dissemination. Oncological initial staging was negative regarding. An ultrasound examination of the lymphatic system of the neck was followed every six months. Another 67 year old patient (age of diagnosis MCC) was followed for 2,5 years. There was a suspicion of a metastatic process in the same side salivary gland and lungs, therefore chemotherapy was performed. Definitely, this process has not been proven. Now there is continuing follow up without sings of local recurrence or metastatic dissemination. CONCLUSION: The authors confirmed a rare occurrence of MCC, and only 0,37% among malignant eyelids tumors. Essential importance for successful treatment is a sufficiently radical excision supported by histological verification and a subsequent plastic surgery of the eyelid is also necessary. Key words: Merkel cell carcinoma, tumor of eyelid, ultrasound examination of nodes.

The long-term monitoring of sympathetic ophthalmia in the diagnostic and terapeutic view. Review Department of Ophthalmology.

AIM: To evaluate options of diagnostic and therapeutic procedures of sympathetic ophthalmia (SO) compared with literature data. Backgroud: SO is an ocular autoimmune disease. It is characterized by disbalance in the imunoregulatory T-subsets within cell mediated immune response. METHODS: File examination of SO by evaluation humoral and cellular immunity was ranked nukleolar test (NT). It evaulates the current status of lymphocyte activation based on the nucleolar morphology and RNA transcription aktivity. The classical histological examination was supported by immunohistochemical analysis of lymphocytic subpopulations in the eyeball enucleated for. SO in one case. MATERIAL: Five boys and men overall were monitored and treated in two studies from 1979 to 1994 and from 1999 to 2017 with SO In four cases it was subsequent after penetrating injuries and once after lensectomy with vitrectomy. The age of patients in the time of onset of SO was between 4 and 24 years (average 12 years). The time interval between insult and onset of SO varied between 10 days and 3 months (average 1.7 months). The relaps of disease appeared in the all cases in the time interval from 3 months to 38 years (average 15 years). Another two patients with SO were examined only in consultation: 16 years old boy with relaps of SO after cataract extraction and 71 years old women with SO subsequent after lensectomy and vitrectomy. There was examined and compared group of 19 patients with other types of uveitis in the same time. The lens-associated uveitis were caused after ocular contusion and penetrating eye injury in 16 patients (13 male patients). In another three cases (young women) with uveitid underlined by II. or III. type of hypersenzitivity the enucleation of dolorous eyeball calmed down the secondary uveitis on their second eye without any change of immunosupressive treatment and without change in NT. RESULTS: There were changes in the complex immunological laboratory tests results in the SO cases in the counts of activated lymphocytes in the peripheral blood. The count of activated lymphocytes was increased in SO cases unlike in lens-associated uveitis. There was detected in NT statistically significant difference (p = 0,0134) between the two groups of uveitis. The histological examination (5 eyes with SO and 7 eyes without sympathetic uveitis) confirmed the diagnoses, supporting basically the clinical diagnosis. The immunohistochemical examination corfirmed the presence of populations of T-lymphocytes, macrophages and also B-lymphocytes. A basis of immunosuppressive therapy was the combination of prednisone and azathioprin at the first time. Effective therapy featured cyklosporine later. CONCLUSION: The nucleolar test of lymphocytes draws attention of their up-to-day increased activity without the diferentiation of subpopulations and their absolute number increase related to the current activation of type IV. hypersensitivity (cell-mediated) in uveitis mechanism. The immunosupressive therapy calmes down this activation predominantly in SO, but also in other case sof uveitis with different types of hypersensivity. The immunohistochemical examination illustrates different presence of lymphocytic types according to the stage of SO.

Sarkoidosis and its Eye Ocular Manifestation (an Analysis of Six Case Report).

AIM: To introduce the range of eye changes in sarcoidosis in the individual casuistics. MATERIALS: At the Ophthalmic Clinic of Teaching Hospital Královské Vinohrady in Prague were examined and treated six patients with ocular forms of sarcoidosis in the years from 1998 to 2015. Three patients were unilateral lesions of the lacrimal gland without systemic symptoms. One patient experienced orbital inflammatory syndrome that accompanied the hilar form of pulmonar sarcoidosis. Two other patients underwent intraocular inflammation, panuveitis / iridocyclitis and bilateral intermedial uveitis. Both of these patients also had systemic affections of mediastinal lymph nodes and lung, in the first of these, signs of neurosarcoidosis first appeared. RESULTS: In the treatment of lacrimal glands, the diagnosis was determined by histological examination of the removed lacrimal gland in external orbitotomies, also, the orbital process has been verified by biopsy and the subsequent comprehensive examination revealed the systemic process. Definitive diagnosis of sarcoidosis was established bioptically in both uveitides and has also been demonstrated in imaging methodologies including galli scintigraphy. All patients were successfully treated with corticosteroid therapy. CONCLUSION: Biopsy results have always been a surprise in orbital processes. Both cases of uveitis were associated with systemic involvement and initiated comprehensive investigation which showed the need for interdisciplinary collaboration in the diagnosis and treatment of sarcoidosis. Key words: sarkoidosis, biopsy, corticosteroids, gallii scintigraphy, MRI, uveitis.

[Two synchronous malignancies in a single nephrectomy specimen]. / Zwei synchrone Malignome in einem Nephrektomiepräparat.

We report a case of a 65-year-old man examined for hematuria and neurologic symptoms. Radiologically a tumour of the kidney was suspected, with metastatic involvement of the brain and both lungs. The urologists then performed a cytoreductive nephrectomy.In histopathological examination of the nephrectomy specimen a clear cell renal cell carcinoma (clear cell RCC) was found. However, an additional focus of a high-grade adenocarcinoma was discovered that turned out to be a metastasis of a poor differentiated lung adenocarcinoma. This diagnosis was supported by positive TTF1 and napsin-A as well as good clinical correlations.The article summarizes the differential diagnostic considerations of poor differentiated adenocarcinoma of the kidney, aimed at gross and microscopic morphology, immunohistochemistry and clinical-pathological correlation. A review of literature about a tumour-in-tumour metastasis is included.

[About Cryptophthalmos (2nd Czech Study)]. / O KRYPTOFTALMU (2. ceská studie).

AIM: To get acquainted with the 2nd Czech study about cryptophthamos and with self-surgical methods. MATERIAL: The boy with unilateral complete cryptophthalmos of left eye was treated from 2 to 20 years. The girls was treated from 4 month to 5 year yet for right abortive cryptophthalmos with microblepharon and left complete type still waiting for solutions.Surgical methods and results: Authors present a surgical procedures for correction of the upper and lower eyelids and ocular anomalies both patients studied. Successful reconstruction of palpebral fissure took place in several stages at the boy. The surgical procedure gradually contained: the insertion of gradually increased convex concave circular-shaped implant (silicone ruber) due a modeling of palpebral fissure, an enucleation of rudimentary eye, a reconstruction of bottom palpebral fissure by retro-auricular skin graf and a releasing of the lower transitory fold by the cul-de-sac method. An adequate depth of palpebral fissure to allow perfect position of an aesthetic protesis. Enucleated eye was atypically shaped, remiding partly sand-glass clock. The cornea was replaced by thick fibrous membrane, the iris and the lens were not revealed. Gliomatic retina was detached nearly totaly and the optic nerv was rudimental. The repairing the upper lid coloboma of girl by a lid rotation flap reconstruction using the inferior eyelid was performed at the age 17 month. Corneal dermoid simultaneously removed (histologically verified). Upper conjunctival fornix was formed using the spherical covering foil (silicone rubber) before and after the reconstruction of the lid. CONCLUSIONS: Plastic reconstructions required the need for patient access without trying immediate effect. An important role played silicone rubber implants (elastomer medical grade) which used temporarily. KEY WORDS: cryptophthalmos, microblepharon, relief surgery, silicon ruber implants.

[Lymphangioma of the orbitopalpebral area]. / Lymfangiom orbitopalpebrální oblasti.

AIM: The authors refer about five patients with different types of lymphangioma, who were followed-up at the Department of Ophthalmology, Faculty Hospital Královské Vinohrady (Kings Vinegards), Charles University, Prague, Czech Republic, E.U., during the period 1995 - 2013; the follow-up period lasted from 5 to 17 years. The lymphangioma of the orbitopalpebral area is discussed according to the evaluation of the tumor development, histological verification, treatment, and its results. METHODS: In four boys, the first signs of tumor were eyeball protrusion (exophthalmos) and bleeding into the conjunctiva or palpebral skin before the age of 5 years. In all four patients, the histological confirmation of the orbital lymphangioma was performed in the beginning of the disease. In three cases, it was the orbital type, and the fourth one was frontal type with bilateral orbital lymphangiomatosis. In one girl, there were present conjunctival changes only, appearing as one-sided hyperplastic changes. For these changes, she was followed-up since her 13 years of age under the false diagnosis of chronic conjunctivitis. The definite histological confirmation of only conjunctival lymphangioma was done from the diagnostic probatory biopsy not until ten years of symptoms and unsatisfactory treatment. RESULTS: In the girl with superficial conjunctival lymphangioma and in the patient with lymphangiomatosis, the follow-up was recommended only. In two patients with extraconal type of orbital tumor, the total or sub-total resection was performed. In the years of the follow-up, the remission of the disease was observed. In the patient with mostly intraconal type of the tumor, causing decrease of the visual acuity according to the optic nerve neuropathy and macular cystoid edema, the focused actinotherapy by means of linear accelerator treatment with the dose of 30 Gy after previous evacuation of chocolate cysts under ultrasound control. The regression of the tumor and normalized visual functions lasted for 17 years. CONCLUSION: As method of treatment of extraconal lymphangiomas, it seems, it is its resection, and in the intraconal localization of the tumor it is the focused actinotherapy by means of linear accelerator.Key words: orbital lymphangioma, conjunctival lymphangioma, lymphangiomatosis, tumor resection, linear accelerator actinotherapy.

[Sarcomatoid (metaplastic) spindle cell carcinoma arising in a phylloid tumor with massive squamous metaplasia - a case report and review of the literature]. / Sarkomatoidní (metaplastický) vretenobunecný karcinom prsu vznikající ve fyloidním tumoru s rozsáhlou skvamózní metaplázií - kazuistika a prehled literatury.

UNLABELLED: A 76-years-old woman underwent a partial mastectomy and a low-grade malignant homologous phyllodes tumor measuring 45 mm in maximum diameter was diagnosed. Beyond its typical dual composition the tumor displayed extensive intraductal squamous metaplasia. Approximately in one third of the lesion the original mesenchymal component cytologically and structurally changed which ultimately led to seeming stromal overgrowth. The loose storiform background contained isolated larger atypical elements with ample eosinophilic cytoplasm and obvious mitotic activity. This final fibromatosis-like arrangement was completed either by multiple dispersed abrupt squamous morules or just by pearl-like abortive form of squamous differentiation. Conventional in situ or invasive ductal carcinoma was not present. A combined expression of both low and high molecular weight cytoketatins, S100 protein, p63, CD10 and GFAP confirmed the incomplete basal/myoepithelial phenotype and ultimately led to the diagnosis of a spindle cell metaplastic carcinoma arising in a phyllodes tumor - a neoplasm unpublished so far. A review of the literature concerning epithelial malignancies originating from a milieu of phyllodes tumor guides discussion/speculation over the possible histopathogenesis of this vanishingly rare lesion. KEYWORDS: breast - phylloid tumor - phyllodes tumor - spindle cell sarcomatoid/metaplastic carcinoma - squamous metaplasia.

[The application of Dysport® - the possibilities of the side effect on the eyelids position (a clinical - histological study)]. / Aplikace Dysportu® - moznost doprovodného vedlejsího efektu na postavení vícek (klinicko-histologická studie).

AIM: To inform about the possibility of negative influence of repeated application of the botulotoxine A derivate on the eye lid position with the changes of their tissue structure. At the same moment, the authors report on literature analysis of positive and negative influence of this neuro toxine from the medical point of view. MATERIALS AND METHODS: At the Department of Ophthalmology in the Faculty Hospital Královské Vinohrady, Prague, Czech Republic, E.U., there were surgically treated three patients after repeated applications of botulotoxine A derivates. The first case was bilateral ptosis of upper eyelids; the other two were indicated because of entropium with trichiasis of lower eyelids. In the medical history, there was recorded ten years lasting above-mentioned drug treatment for blepharospasm diagnosis in a 65 years old man introducing bilateral symmetrical ptosis. Because of the following frontal muscle involvement, and partial decreasing levator palpebrae muscles function, the positioning of the upper eyelids was treated by the aponeurosis plasty with good functional result. In two female patients, aged 72 and 90 years, the indication for successful surgical treatment was chronic entropium of lower eyelids; initially ineffectively treated by means of repeated intradermal injections of botulotoxin A derivates. RESULTS: Histological examinations of the excided skin and subcutis samples taken during ectropium plasties showed unfavorable and irreversible changes including especially scarring of the eyelid and atrophy of the striated muscles. CONCLUSION: The indication of botulotoxine A derivates application should be carefully weighted and the proper indication should be chosen. From the ophthalmologic point of view, blefarospasmus only is the appropriate diagnosis, and the relative indication is the temporary induced ptosis of the upper eyelid closing the interpalpebral fissure to prevent corneal changes in lagophthalmos of various etiologies as an alternative to the tarsoraphy. Always we have to consider the frequency of applications, because repeatedly used derivate of this neurotoxine causes irreversible changes in cutaneous and subcutaneous tissue.

Evaluation of the usability of a brief computerized cognitive screening test in older people for epidemiological studies.

BACKGROUND: Computerized cognitive testing has the potential to be an effective way to assess and monitor cognition in large neuroepidemiological studies. CogState is a game-like computerized test with demonstrated validity and reliability that has shown sensitivity to decline in older individuals over time. This study aimed to evaluate the serial usability of the test specifically within an older community cohort. METHODS: The test battery was administered to healthy volunteers aged 50 years and above at 3-month intervals over 12 months in a community setting. Test usability was examined in terms of acceptability, efficiency and stability. RESULTS: Of 301 subjects (age: 61.9 +/- 7.2 years), 87% completed the study. In addition, 85% completed the first test within the allowed time and passed integrity criteria with their performance improving and stabilizing at subsequent visits. The computerized battery required 15 min for administration on average, allowing 263 patients to be assessed on 5 occasions by 2 assessors. All tasks showed stability and a high test-retest reliability with serial administration. CONCLUSIONS: This computerized test was shown to have good acceptability, efficiency and stability for the repeated assessment of cognitive function in older people. Together with its demonstrated sensitivity to cognitive impairment and cognitive change, these data suggest that it would be a useful tool for application in neuroepidemiological studies.

[Malignant masquerade syndromes]. / Maligní maskující syndromy.

PURPOSE: To evaluate our experience with the diagnosis and treatment of malignant masquerade syndromes. METHODS: A retrospective study of 46 patients treated for malignant masquerade syndromes at our Department for Diagnosis and Treatment of Uveitis, 1st Faculty of Medicine in Prague, between 1995 and 2008, was performed. RESULTS: Eighty-nine patients with masquerade syndromes (7.2%) from all 1233 patients with uveitis were included. Malignant masquerade syndromes were recognized in 46 patients (22 females and 24 males, mean age 55 years). The most frequent cause of malignant masquerade syndromes was intraocular non-Hodgkin lymphoma (26 patients). The primary diagnosis was idiopathic uveitis in many cases. The most valuable diagnostic procedure was analysis of intraocular fluids. CONCLUSION: Diagnosis of masquerade syndromes should be considered in all patients with idiopathic corticosteroid-resistant chronic uveitis. Timely diagnosis and treatment may in case of malignant masquerade syndromes improve prognosis and sometimes gain control over this potentially lethal disease.

[The follow up of prognostic important factors and analysis of five years survival rate in patients with uveal melanoma at the Department of Ophthalmology, 3rd Medical Faculty Charles University in Prague and the Faculty Hospital Královské Vinohrady in Prague]. / Sledování prognosticky významných faktoru a analýza petiletého prezití pacientu s uveálním melanomem na Ocní klinice 3. LF UK a FNKV.

The analysis of survival and the influence of the followed up prognostic important factors to the duration of survival in 51 patients with uveal melanoma, treated by enucleation of the eyeball was evaluated by means of Kaplan-Meier analysis and Cox regression model. The study was performed at the Department of Ophthalmology of the 3rd Medical Faculty, Charles University in Prague and the Faculty Hospital Královské Vinohrady in Prague, Czech Republic, E.U., during the period 1999 to 2007. The mortality rate with the association to the general diagnosis was 35.5%. By means of the statistical analysis of survival, (Kaplan-Meier analysis) we established that these followed up prognostic factors are important for the duration of the survival period: pTNM (pathologic tumor-node-metastasis) (p = 0.00032), the size of the tumor (p = 0.01603), mitotic activity (p = 0.028889), and the rupture of the Bruch's membrane (p = 0.1446). The Cox regression model specifying which of the independent entry values correlates mostly with the period of survival, or the date of death respectively, showed that the strongest correlations with the period of survival duration had in our group the pTNM classification.

[Orbital tumors in adults--a 10-year study]. / Orbitální tumory u dospelých--desetiletá studie.

UNLABELLED: The authors refer about diagnostic procedures, treatment and follow-up of 87 adult patients with orbital tumors during the period 1998 - 2007 in the Department of Ophthalmology, Faculty Hospital Královské Vinohrady, Charles University, Prague, Czech Republic, E.U. The group consists of 42 men and 45 women, age range 18-89 years. In 49 patients, the tumors were of benign origin (age 18-80 years, median, 48 years), and 38 patients suffered from malign tumors (age 38-89 years, median, 61 years). Among basic examinations methods ranked the magnetic resonance imaging and the histological verification of the tumor. Sixty-four tumors were treated by means of 70 surgical procedures. The anterior diagnostic or therapeutic orbitotomy was used in 72.5% of the cases, lateral osteoplastic orbitotomy (Kronlein) in 14.5%, and exenteration of the orbit in 13% of the cases. Altogether 23 patients were treated without surgery by means of corticosteroids, or are followed-up due to a benign tumor only. As the most common, the inflammatory pseudotumors of the orbit were diagnosed in 40%. Clinically they were of the anterior nodular, or posterior diffuse form, dacryoadenitis or orbital myositis. All patients were treated by means of prednisolon for at least three months; due to the relapse of the immunopathologic process, in 16 % of the cases the therapy was supplemented with azathioprime. The surgical procedure was the choice of treatment in 66% of inflammatory processes in the lacrimal gland region. In four cases the sarcoidosis was established.The second tumor in the final ranking was lymphoma in 19.5%; the MALT-lymphoma was diagnosed in 59% of these cases. The chemotherapy was chosen for the treatment in 2/3 of the cases, and in all cases the remission was reached.The actinotherapy was chosen especially in other types of lymphoma; the follicular form and "molding" lymphoma were the causes of the death in two patients. Among malignant tumors, the most serious clinical courses were histological different primary carcinomas of the orbitopalpebral region in 14% of the cases, and secondary melanoma spreading from the conjunctiva in 5.5%. Both these tumors, counting the same number as lymphomas, were the only indications to the exenteration of the orbit, and causes of the death in four patients. CONCLUSION: Among orbital tumors in adults, the most common were inflammatory pseudotumor and lymphoma. The decisive procedure was always the histological verification, which directed the following therapy.

[Benign masquerade syndromes in differential diagnosis of uveitis]. / Benigní maskující syndromy v diferenciální diagnostice uveitid.

PURPOSE: To present our experience with the diagnosis of benign masquerade syndromes, to evaluate the prevalence, clinical features and diagnostic tests. METHODS: A retrospective study of 42 patients treated for benign uveitis masquerade syndromes at our Department for DIAGNOSIS AND TREATMENT OF UVEITIS: 1st Faculty of Medicine in Prague, between 1996 and 2006, was performed. RESULTS: Seventy-nine patients with masquerade syndromes (7.1%) from all 1112 patients with uveitis were included. Malign masquerade syndromes were recognized in 37 patients (19 females and 18 males, mean age 55 years) and benign masquerade syndromes in 42 patients (23 females and 19 males, mean age 33.7 years). The most frequent cause of benign masquerade syndromes was a group of vascular anomalies (22 patients). The primary diagnosis was infectious or idiopathic uveitis in many cases.The most valuable diagnostic procedures were fluorescein angiography and analysis of intraocular fluids. CONCLUSION: Diagnosis of masquerade syndromes should be considered in all patients with idiopathic corticosteroid-resistant chronic uveitis. Timely diagnosis and treatment may improve the prognosis of masquerade syndromes.

[Leiomyoma of the abdomen wall. Case report]. / Leiomyom piední steny birisní.

Authors present the case report of the patient indicated to plastic of abdomen wall for large hernia. Per operation, tumor was found without communication with abdomen cavity and organs. Histopathologically, leiomyoma of the abdomen wall was identified.

[Optical coherence tomography in pars plana vitrectomy for idiopathic macular hole]. / Optická koherentní tomografie u pars plana vitrektomie pro idiopatickou makulární díru.

26 eyes of 25 patients after macular hole surgery were followed-up for 6 months in average (range of 2-25 months). The overall anatomic success rate was 77 %. The internal limiting membrane was peeled after its staining with trypan blue in all closed macular holes. The macular hole surgery resulted in anatomic success of stage Ib or II in 11 (100 %) eyes, of stage III in 7 (64 %) eyes and in stage IV in 2 (50 %) eyes. There was an improvement or a stabilisation of the best corrected visual acuity (BCVA) in 85 %. BCVA improved from 4/20 to 4/12 in average. 45 % of patients with closed macular hole attained BCVA 4/10 or better, 5 (25 %) of them with the best visual acuity at presentation improved to 4/8 in average. In 23 % cases of clinically normal fellow eyes, optical coherence tomography (OCT) detected an abnormality of the vitreoretinal surface. OCT is essential for evaluation of anatomical success after macular hole surgery. It is necessary to perform it also in a fellow eye to exclude clinically silent abnormality of the vitreoretinal surface.
