[Onco-TESE and testicular cancer]. / Onco-TESE et cancer du testicule.

INTRODUCTION: Fertility preservation is essential before cancer treatment. When ejaculated sperm preservation is not possible, testicular tissue can be surgically collected by Onco-TESE technic (Oncological Testicular Sperm Extraction) to isolate sperm. We report on our experience with Onco-TESE in testicular cancer patients at the Rouen University Hospital. MATERIAL AND METHOD: Retrospective study including all pubescent men, treated for testicular cancer, uni- or bilateral, before any carcinological therapy, who have undergone Onco-TESE at the Rouen University Hospital. Fragment weight, detection of sperm or its precursors were analysed. A histological interpretation of the testicular tumor was carried out. For each positive sample, straws were kept at the French Sperm Bank. RESULTS: Twenty-four patients had an Onco-TESE: 58.34% severe sperm alteration (SSA) and 41.36% sperm collection failure (SCF), between 1996 and 2019. The mean age was 26.6 (±5.29) years. The mean procedure and length of stay were 71minutes (±30.7) and 3.75 days (±2.83), respectively. The rate of positive testicular biopsies (TB) was 58.33% overall and 66,67% in the case of TB on tumour testis. One patient had a Clavian-Dindo III complication. The mean number of straws preserved per patient was 14.28 (±15.34) for 7.14% use. CONCLUSION: Our results seem to confirm that Onco-TESE is an effective solution for preserving fertility in men with testicular cancer in cases of SSA or SCF. LEVEL OF EVIDENCE: III.

[Renal Trauma]. / Traumatismes du rein.

INTRODUCTION: Renal traumas are common, observed in 10% of patients with abdominal trauma. Most renal traumas are blunt, resulting from a direct hit or from an abrupt deceleration. MATERIAL AND METHODS: We realized a synthesis of renal trauma management for nurses. RESULTS: Clinical presentation often encompasses gross hematuria and lumbar pain. The best diagnostic tool is computed tomography (CT) urogram. Based on CT urogram images, renal traumas are classified according to the American Association for the Surgery of Trauma (AAST) classification in five grades of increasing severity. The management is conservative in the vast majority of cases and has been largely simplified over the past few years, being now mostly based on observation. Radiological interventional and endoscopic procedures are used only in very selected cases and surgical exploration has become extremely rare. CONCLUSION: The prognosis has also considerably improved and renal trauma rarely result in death or loss of the kidney nowadays.

[Partial nephrectomy vs. radical nephrectomy for tumor>7cm]. / Résultats de la néphrectomie partielle pour les tumeurs de plus de 7cm : comparaison avec la néphrectomie élargie.

INTRODUCTION: The usefulness of partial nephrectomy (PN) has been demonstrated for the treatment of renal tumor<7cm and it is now the standard treatment for such lesions. However, few studies are available regarding tumors≥T2. The objective of this study was to assess PN results for the treatment of renal tumors>7cm. MATERIALS AND METHODS: A retrospective two-center study was performed, including 170 patients treated. Thirty-two patients underwent PN and 138 radical nephrectomy (RN) for renal cT2 tumors between 2004 and 2014. The biological and clinical characteristics including perioperative morbidity as well as the survival rate were compared between these 2 groups. RESULTS: The median age was 59.5 years and the median follow-up was 47 months. More cT2b tumors were treated through RN (34.1% vs. 12.5%, P=0.01). The postoperative decrease in creatinine clearance was higher for the RN group (-24.3mL/min vs. -16.8; P=0.04). This difference was no longer significant at last follow-up. Perioperative complications were more frequent in the PN group (50.0% vs. 18.1%; P=0.008), and more severe (Clavien≥3 18.7% vs. 5.1%, P=0.01). No difference was found regarding the overall survival. Surgical margins were more frequent in the PN group (9.1% vs. 0.85%; P=0.01). CONCLUSION: Our results suggested the feasibility of PN for renal tumors>7cm, involving however a higher perioperative complication risk. Cautious patient selection appeared to be required for the indication of PN for large tumors. LEVEL OF EVIDENCE: 4.

Epidemiology and prognostic factors of open globe injuries in a Tunisian pediatric population.

INTRODUCTION: Childhood ocular trauma is a preventable cause of visual impairment and blindness worldwide. The purpose of our study was to determine demographic, etiologic, and clinical characteristics, visual outcome, and factors affecting visual prognosis in children with open globe injuries (OGI) and to analyze the predictive value of ocular trauma scoring systems for OGI in children. METHODS: We conducted a retrospective study enrolling 120 pediatric patients hospitalized for OGI from January 2010 to March 2017. Age, gender, date of trauma, time between trauma and presentation, place and circumstances of injury, etiology, visual acuity (VA), wound location and type of injury based on the Birmingham Eye Trauma Terminology, and the clinical signs were recorded. We recorded the number of surgical procedures performed, complications and visual outcomes. RESULTS: The mean age was 7.38 years. In all, 62.5% of the patients were male, and 37.5% were female. The gender ratio was observed to decrease with increasing age. The mean time interval between injury and consultation was 22.80±42.68hours. Injuries usually occurred at home (80%) followed by playgrounds and sports venues (8.3%), the street (6.7%) and school (5%). All of the OGI's were accidental, and the main context was play (70%). The most common traumas were penetrating injury (60.8%) and metal (30%) objects. Penetrating trauma accounted for 68.3% of cases, followed by rupture (27.5%) and intraocular foreign body (IOFB) (7.5%). Initial VA was<1/10 in 59.2% of cases, and the point of entry was the cornea in 65.8% of cases. Final VA was<1/10 in 39.69% of all cases. FVA was significantly correlated with BCVA prior to the surgery, mechanism of the trauma, wound location and size, and other associated lesions. The Ocular Trauma Score (OTS) and the Pediatric Ocular Trauma Score (POTS) were significantly correlated with final VA. CONCLUSION: OGI's in children occurs most frequently in school-age boys. Prognosis is determined by presenting visual acuity, trauma score, and wound severity and location.

[Radiotherapy in the treatment of retinoblastoma: about 40 cases]. / Place de la radiothérapie dans le traitement du rétinoblastome : à propos de 40 cas.

PURPOSE: The aim of this study is to analyze the results and the complications of radiotherapy in the treatment of retinoblastoma. PATIENTS AND METHODS: Between 1994 and 2004, 40 children received radiotherapy for a retinoblastoma in Salah Azaiz Institute. The average age of the patients was 36 months (four to 132 months). There were 16 girls and 24 boys. Sixteen children presented a bilateral disease and 24 children a unilateral disease. Twenty eyes and thirty-six orbital cavities in 40 children with retinoblastoma were treated by radiotherapy. One child with a unilateral anterior retinoblastoma was treated with 106 ruthenium brachytherapy. External radiotherapy has been used to treat the 39 patients. In 20 cases the irradiation was conservative and in 36 cases postoperatively. The latter (n=36) presented at least one risk factor of relapses noted in the histological examination. The average dose was 44 Gy (1.8 to 2 Gy per fraction, five fractions weekly). This radiotherapy was associated with chemotherapy in 24 cases. RESULTS: Thirty-five children were followed with an average follow-up of 53 months (3-108 months). The average delay of relapses was of 10 months (two to 26 months). We found four orbital relapses and seven metastasis in nine children. The conservation of the eye with a useful visual field was noted in 18 cases among the 20 conservative irradiated eyes. The major therapeutic complication was the growth defect of the bones face. A femoral bone sarcoma was noted five years after the end of the irradiation and chemotherapy in one case. CONCLUSION: If the radiotherapy offers the advantage of the functional conservation and the improvement of the local control, its indications are more and more restricted in favor of the other therapeutic methods (chemotherapy, thermochemotherapy) and this considering the iatrogene risk. The development of new techniques of brachytherapy and the progresses of the conformational radiotherapy appear to reduce considerably this risk.

[Radio-histological correlation of microcalcifications of the breast: a Tunisian center experience]. / Corrélation radio-histologique des microcalcifications du sein. Experience d'un centre Tunisien.

PURPOSE: Evaluation of surgical biopsy for mammary microcalcifications, in Tunisian patients according to the American College of Radiology's recommandations (ACR). MATERIAL AND METHODS: [corrected] 100 patients treated in Salah Azaiez Institute from January 2005 to December 2006, who underwent surgical biopsy for breast microcalcifications The diagnosis was based on mammography associated in 60% of the cases, to ultra-sonography. We correlated biopsies results to ACR classification. RESULTS: 123 surgical biopsies are related to ACR 3 lesions in 72 cases (58.5%) ACR 4 in 39 cases (32%) and ACR 5 in 14 case (11.5%). The histological examination showed malignant lesions in 4 cas/72 ACR3 (5.5%), 19/39 ACR4 (48.7%) and 10 among the ACR5 (71.4%). CONCLUSION: Our preliminary study introduces a diagnostic approach of mammary microcalcifications, that are usually infra-clinic lesions, in a general context of breast tumors detected with an average size of more than 3 cm.

Hymenoptera insect stings: Ocular manifestations and management.

PURPOSE: To describe the ocular findings and management of Hymenoptera insect stings. METHODS: We treated and followed 8 patients with ocular Hymenoptera stings. All patients were admitted through emergencies and hospitalized at the Hedi Rays eye institute in Tunis. RESULTS: The site of the sting was the cornea in 5 cases, limbus in one case, conjunctiva in one case and upper lid in the last case. Retained stingers were objectified in 4 cases. Immediate surgical extraction carried out in all cases. We also followed one case of post-sting Adie's syndrome and one case of retrobulbar optic neuritis. The sting was conjunctival in one case and palpebral in the other case. Corticosteroids were ineffective in these two cases. CONCLUSION: Ocular Hymenoptera stings are rare environmental accidents. They may cause various severe ocular complications. Early management, adapted to the clinical manifestations, is the key to a good outcome.

[Diabetic papillopathy after intensification of insulin therapy: A case report]. / Papillopathie diabétique après insulinothérapie intensive : à propos d'un cas.

INTRODUCTION: Diabetic papillopathy is a rare ocular complication of diabetes. Its pathophysiology is not well known. It is a unilateral or bilateral optic disc edema with variable degrees of visual loss. OBSERVATION: A 66-year-old woman, with a twelve years old type 2 diabetes mellitus, suddenly presented a unilateral decreased vision. Her ocular examination was normal eight months earlier. Ocular examination, radiological investigations and laboratory analysis were conclusive of diabetic papillopathy. Medical history revealed a recent rapid improvement of blood glucose control after intensification of insulin therapy. A visual acuity improvement with spontaneous regression of papillary edema was observed. CONCLUSION: There is a risk of diabetic papillopathy associated with the rapid control of blood glucose levels after intensification of insulin therapy, even in diabetic patients without known retinopathy.

Ligneous conjunctivitis due to plasminogen deficit: Diagnostic and therapeutic approach. With literature review.

Ligneous conjunctivitis is a rare and poorly understood pathology. Infections and repeated microtraumas are often involved in acute disease flare-ups. This masquerade may lead to misdiagnosis and delayed treatment. We report two cases of ligneous conjunctivitis, describing various presentations of its natural history and focusing on the treatment of this rare disease.

[Brain radionecrosis in patients irradiated for nasopharyngeal carcinoma: about nine cases]. / Radionécrose cérébrale chez les patients irradiés pour cancer du nasopharynx: à propos de neuf cas.

PURPOSE: To study the clinical, radiological, therapeutic and progressive aspects of brain radionecrosis after treatment for nasopharyngeal carcinoma. PATIENTS AND METHODS: Nine patients (seven men and two women) of mean age 47.7 years old (extremes: 18-57 years old) were treated for UCNT (undifferentiated carcinoma of the nasopharynx) between 1989 and 2003 and developed cerebral radionecrosis. All patients were treated with radical radiotherapy. The mean total dose was 73.5 Gy (70-75 Gy). Dose per fraction was 2 to 2.5 Gy, one fraction daily. One patient received adjuvant brachytherapy to the dose of 8 Gy and four patients also received chemotherapy. RESULTS: Brain radionecrosis was authenticated by brain imaging (CT scan+/-MRI): the imaging was ordered in seven cases to elucidate non-specific neurological signs and two cases were discovered fortuitously. The time to the appearance of neurological signs was 40.3 months (10 to 108 months). The localization was temporal in six cases, parieto-occipital (one case) and bulbomedullar (two cases). After a mean follow-up period of 30.6 months (12-84 months), clinical outcomes were favorable in all cases receiving medical treatment (corticoids), with a stabilization of the radiological lesions in eight cases and complete radiological regression in one patient. CONCLUSION: Brain radionecrosis is a late complication rarely occurring in patients irradiated for UCNT. Imaging techniques (CT scan but more so MRI) play a major role in the diagnosis. Corticotherapy resulted in a durable objective response in all patients and, in most cases, resulted in radiological stabilization.

[Pelvic pseudotumoral actinomycosis with multisegmental lumbosacral root failure. A case report]. / Actinomycose pelvienne pseudotumorale avec atteinte multiradiculaire lombosacrée. A propos d'un cas.

We report a case of pseudotumoral pelvic actinomycosis with lumbosacral spinal involvement in a 21 year-old woman. The radiological work-up showed a pseudotumoral left ovarian lesion extended to sacral spine, which involved the fifth lumbar vertebra. Diagnosis of actinomycosis was established in histopathological examination of the tubo-ovarian mass under laparotomy. After four months of treatment with ofloxacin and rifampicin evolution was marked by improvement of general health and infection, associated to a progressive recovery of motricity of the lower limbs. Early diagnosis of pelvic actinomycosis may prevent the occurrence of rare but severe neurological complications of this disease.

[Mammary tuberculosis: a retrospective study of 65 cases]. / Tuberculose mammaire: étude rétrospective de 65 cas.

OBJECTIVES: Remember the clinical, morphologic and histological particularities of mammary tuberculosis. Discuss clinical and radiological diagnostic problems caused by this localization, as far as breast cancer is concerned. PATIENTS AND METHODS: This is a retrospective study concerning 65 women suffering from mammary tuberculosis, diagnosed at Salah Azaiez Institute between January 1980 and December 2001. RESULTS: In this series, mammary tuberculosis represents 0.2% of the declared tubercular localizations and 0.3% of the mammary pathologies treated at the institute. The mean age of our patients was 36 years (19 to 79). Clinical findings were misleading. In 60% of cases the aspect was of a malignant tumor, in 24.6% of cases of a benign nodule and in 16.4% of cases of an abscess. The mammography concluded to a malignant lesion in 49% of cases. The fine needle aspiration achieved at 8 patients was negative in 6 cases and brought back the caseum in the 2 others. The diagnosis has been made, for all our patients, after histological study when we found typical tuberculosis lesions on pieces of tumorectomy, or biopsy. The diagnosis of tuberculosis was established; all patients had an anti-tuberculosis medical treatment in a department of infectious diseases out of the institute. DISCUSSION AND CONCLUSION: Clinical and radiological features of mammary tuberculosis are very confusing and cause a diagnostic problem with breast cancers. In front of symptoms evoking tuberculosis, biopsies must be done to eliminate an eventual cancer.

[Macula analysis by spectral domain OCT in rhegmatogenous retinal detachment surgery]. / Analyse de la macula par OCT spectral domain dans la chirurgie du décollement de rétine rhegmatogène.

INTRODUCTION: Despite surgical reattachment of retinal layers, postoperative functional outcomes after rhegmatogenous retinal detachment (RRD) may be limited. This can be explained by microstructural changes in the macula inherent to the pathology itself as well as the surgery. PURPOSE: To evaluate the various changes in the macula by OCT pre- and postoperatively, and correlate them with functional and clinical outcomes in patients with RRD. To establish pre- and postoperative prognostic factors. METHODS: This was a prospective study of 50 eyes of 50 patients operated for RDD. Each patient underwent a complete clinical examination and macular OCT using the Heidelberg Spectralis; preoperatively and then successively at 7 days, 1 month, 3 months and 6 months after RRD surgery. RESULTS: Preoperative tomographic results revealed an average height of submacular fluid of 742 ± 345 µm. Ninety-six percent of patients exhibited thickening of photoreceptor outer segments (PROS), 62% an outer layer undulation, 60% cystic cavities in the outer and/or inner nuclear layers (ONL, INL), 36% disruptions of the external limiting membrane (ELM) and 64% disruption of the IS/OS junction. Postoperatively, 24% of patients had persistent submacular fluid. The average thickness of the central fovea, the ONL, the IS/OS junction and the PROS were 172 ± 51.3 µm, 88.4 ± 30.9 µm, 11.36 ± 5.4 µm and 19.54 ± 13.1 µm respectively. Postoperative disruptions of the ELM, the IS/OS junction and Verhoeff's membrane (VM) were present in 24%, 60% and 82% of patients respectively. The preoperative tomographic risk factors for poor visual outcome were: submacular fluid height > 800 µm (P<0.001), disruptions of the MLE and/or IS/OS junction (P<0.001), as well as cystic cavities in the ENL and/or INL (P=0.002). Postoperative risk factors were: thinning of the fovea (≤ 250 µm), central fovea (≤ 160 µm), ONL (≤ 90 µm), IS/OS junction (≤ 10 µm) and PROS (≤ 18 µm) layers (P<0.001), as well as a discontinuous or absent appearance of the ELM (P<0.001), IS/OS junction (P<0.001) and VM (P=0.006). CONCLUSION: Spectral domain OCT allows detection of specific microscopic, quasi-histologic macular changes in rhegmatogenous retinal detachment. These anomalies could be predictive of final postoperative visual outcome.

[Prognosis of primary malignant tumors of the conjunctiva]. / Le pronostic des tumeurs malignes primitives de la conjonctive.

PURPOSE: To discuss possible factors that could influence the prognosis of primary malignant conjunctival tumors. PATIENTS AND METHODS: We retrospectively analyzed medical records of 79 patients followed for primary malignant conjunctival tumors between January 1997 and July 2011. RESULTS: The mean age at the time of diagnosis was 61.1 years; male/female ratio was 2.59. The mean tumor size was 13.9 mm. The histological type was invasive squamous cell carcinoma in 43 cases (54.4%), epithelial dysplasia in 11 cases (13.9%), carcinoma in situ in 7 cases, conjunctival malignant melanoma in 5 cases, conjunctival lymphoma in 4 cases and other rare tumors in 9 cases. We performed an excisional biopsy with a safety margin in 89.8% of cases, associated with cryotherapy in 46.6% of cases. Enucleation was performed in two cases and orbital exenteration in 5 cases. We noted tumor recurrence in 33.3% of patients after an average period of 9.5 months. Radiation therapy was indicated in 44 cases (55.7%). The mean follow-up of our patients was 42 months. Tumor recurrences were statistically associated with a history of xeroderma pigmentosum (P=0.012), a diagnostic delay more than 11 months (P=0.001), caruncular location (P=0.004), tumor size greater than 10mm (P=0.044), scleral extension (P=0.011), initial treatment limited to excisional biopsy (P=0.033) and histopathologic involvement of the margin of the tumor resection (P=0.008). CONCLUSION: A better understanding of the prognostic factors of primary malignant conjunctival tumors is essential for management and may improve the prognosis of these tumors.

[Secondary head and neck osteosarcoma following treatment of undifferentiated nasopharyngeal neoplasms (UCNT)]. / Ostéosarcome secondaire de la tête et du cou après traitement de carcinome indifférencié du nasopharynx (UCNT).

Secondary tumours after radio and/or chemotherapy are mainly of hematopoietic (acute non lymphoblastic leukemia, non-Hodgkin lymphoma) or soft tissue lineage previously described most frequently after breast cancer and Hodgkin disease treatment with radio and/or chemotherapy. We report two cases of classical osteosarcoma's observed 9 and 3 years after treatment for UCNT with combined radiotherapy and alkylant-based adjuvant chemotherapy in one case and exclusive loco-regional irradiation in the second case.
