One-step transepithelial photorefractive keratectomy with mitomycin C as an early treatment for LASIK flap buttonhole formation.

PURPOSE: To assess the efficacy and safety of early one-step transepithelial photorefractive keratectomy (PRK) with mitomycin C as treatment for buttonhole formation during LASIK. METHODS: Eight patients who developed a buttonhole during LASIK with mechanical or femtosecond flap creation underwent one-step transepithelial PRK a few days after the formation of the buttonhole. The re-treatment procedure was performed after complete epithelial healing and smooth epithelial fluorescein profile were ensured. Postoperative manifest refraction, uncorrected and corrected distance visual acuity, and haze formation were assessed during 6 months of follow-up. RESULTS: Mean duration of the re-treatment procedure after buttonhole formation was 5 days (range: 4 to 7 days). Mean manifest refractive spherical equivalent and cylinder refraction were -0.05 ± 0.18 and -0.18 ± 0.22 diopters, respectively, at 6 months postoperatively. Uncorrected distance visual acuity was 20/20 in all patients after 3 months of follow-up. No haze formation was detected. CONCLUSIONS: Early one-step transepithelial PRK with mitomycin C seems to be a safe and effective treatment for LASIK buttonhole complication.

A case report of Sandhoff disease.

Sandhoff disease is a rare and severe lysosomal storage disorder representing 7% of GM2 gangliosidoses. Bilateral thalamic involvement has been suggested as a diagnostic marker of Sandhoff disease. A case of an 18-month-old infant admitted for psychomotor regression and drug resistant myoclonic epilepsy is presented. Cerebral CT scan showed bilateral and symmetrical thalamic hyperdensity. MRI revealed that the thalamus was hyperintense on T(1)-weighted images and hypointense on T2-weighted images with a hypersignal T2 of the white matter. Enzymatic assays objectified a deficiency of both hexosaminidases A and B confirming the diagnosis of Sandhoff disease.

[Tumoral calcinosis: a case report]. / La calcinose tumorale: à propos d'un cas.

Tumoral calcinosis is a rare benign disease, defined by the presence of calcified deposits in periarticular tissues. The pathogenesis is unclear. We report a new case of tumoral calcinosis in a young girl, involving the left hip and both elbows. The clinical exam found a voluminous mass of soft tissues and the radiological exam showed the presence of voluminous periarticular calcifications with no bone involvement. The diagnosis was confirmed by the anatomopathological exam. The treatment remains essentially surgical and the prognosis is very good.

[Cochleovestibular dysplasia: a case report]. / Dysplasie cochléovestibulaire. A propos d'un cas.

Cochleovestibular dysplasia or Mondini malformation is exceptional. Cochlear dysplasia is due to early cessation of the development of the inner ear during embryonic life. We report on the case of an infant who presented with perception deafness and repeated meningitis. CT allowed the diagnosis of Mondini malformation. We underline the importance of high-resolution CT in the diagnosis of Mondini malformation.

[Thumb acrometastasis revealing lung adenocarcinoma: a case report with review of literature]. / Acrométastase du pouce révélant un adénocarcinome pulmonaire: a propos d'un cas avec revue de la littérature.

Bone metastases in the hand and foot bone (acrometastases) are rarely observed. The authors report a case of a 57-years-old man diagnosed as hand tumour, revealing a bronchic adenocarcinoma. Radiography showed destruction of the phalanx, and histology study confirmed a metastasis of the lung cancer.

[Intramedullary rupture of a dermoid cyst of the conus: a case report]. / Rupture intra-médullaire d'un kyste dermoïde du cône. A propos d'un cas.

The authors report the case of a 40 year old patient with history of cauda equina syndrome and pyramidal signs due to intramedullary rupture of a congenital dermoid cyst of the conus without associated spinal dysraphism. Diagnosis was suggested at magnetic resonance imaging (MRI) and confirmed by histological examination and percutaneous aspiration of the intramedullary cavity.

[Paratesticular rhabdomyosarcoma. A case report]. / Rhabdomyosarcome paratesticulaire. A propos d'un cas.

The rhabdomyosarcomas are rare tumors of mesenchymal tIssue. Whose most frequent localisations are génito-urinary, and occur in the child and young adult. It's an intrascrotal tumour, localised in the tunica vaginalis, epididymis or spermatic cord. The Authors report a case of paratesticular rhabdomyosarcoma in a 15 Year old child, who presented a right painless scrotal mass since two Months. The research of the tumoral markers is negative. Scrotal ultrasound shows a tissular mass in spermatic cord. Abdominal ultrasound and CT show retroperitoneal lymph node mass. Chest X-ray is normal. The intervention consists of a right castration. The histological examination of the spiceman confirms the diagnosis of the paratesticular rhabdomyosarcoma of the spermatic cord. The patient is treated by chemotherapy without improvement. Through this observation, the Authors underline the interest of the imagery and the aspects of the paratesticular tumours in ultrasound and CT.

[A new case of abdominal pregnancy]. / Un nouveau cas de grossesse abdominale.

The authors report a case of abdominal pregnancy that reached term. This type of pregnancy is now rare except in developing countries due to lack of early diagnosis. Ultrasonography is useful to confirm a clinically suspected diagnosis. MRI is helpful to further characterize the relation between placental tissue and intra-abdominal organs. Prognosis for the fetus is usually poor, and risks to the mother are non-negligible. Management is typically surgical and placental resection is the main concern. In this case, surgical delivery of an otherwise normal appearing infant was performed.

[Isolated tuberculosis of the spleen. Report of a case]. / Un cas de tuberculose splénique isolée.

Isolated tuberculosis of the spleen is rare and difficult to diagnose. The features and management of this disease are discussed based on one case. A 52-year-old woman, presented with fever of unknown origin and splenomegaly. Ultrasonography and computed tomography demonstrated heterogeneous areas within the spleen. The diagnosis was made by a pathologic study of a splenic fragment obtained during laparotomy. When the spleen is the only organ involved by tuberculosis, the diagnosis is usually made by a pathologic study of splenic tissue obtained during laparotomy or percutaneous needle biopsy.

[Rhino-orbito-cerebral mucormycosis]. / La mucormycose rhino-orbito-cérébrale.

Rhino-orbito-cerebral mucormycosis is a rare fungal infection, invading rapidly the nasal cavity, paranasal sinuses, orbits and intracranial structures. It most often occurs in predisposing conditions (diabetics, immunosuppressed patients). The authors report the case of a diabetic patient who presented with extensive necrotic lesions of the face in spite of appropriate antistaphylococcic therapy. Diagnosis was confirmed by histologic and mycologic tests. The outcome was favorable after Amphotericin B therapy, daily debridement, and optimal control of the diabetes.

[Bilateral and spontaneous hemorrhage of the renal sinus. Report of a case]. / Hémorragie bilatérale et spontanée du sinus rénal. A propos d'une observation.

Renal sinus hematoma is a rare complication of anticoagulant therapy. Prognosis is usually excellent with spontaneous regression. The authors report a case of spontaneous bilateral renal sinus hematoma in a 59-year-old woman, treated by anticoagulants for a cardiac disease. Diagnosis and follow-up are made using computed tomography.

[Imaging of a historical case of vertebral hydatidosis]. / Imagerie d'un cas historique d'hydatidose vertébrale.

Radiological, computed tomography and magnetic resonance imaging findings in a case of spinal hydatidosis are reported.

[Effort phlebitis of the upper limb. Presentation of 2 cases and review of the literature]. / Phlébite d'effort du membre supérieur. Présentation de deux cas et revue de la littérature.

Effort phlebitis, which represented the principal aetiological form of deep vein thromboses of the upper limb, has become rare, while secondary forms, especially iatrogenic, are more frequent. The authors report two documented cases of effort phlebitis of the upper limb in two manual labourers aged 38 and 40 years. The aetiopathogenic and clinical features and clinical course of this disease are analysed.
