Background: Allergic rhinitis is a daily problem to which are confronted principally general practitioner, paediatrician, ear, nose and throat specialist and allergologist. also, this subject is still always alive because allergy seems in a constant progression in our society., Aim: To clarify diagnostic and therapeutic criteria of this affection., Methods: we have realized a literature review concerning physiopathology, clinical symptoms, the position of paraclinical investigations and finally therapeutic modality of allergic rhinitis., Results: Appropriated treatment of allergic rhinitis should be général it requires a knowledge and better comprehension of the disease and optimum prevention, if it is possible, of allergic symptoms.

The hydatic cyst is a pathology observed in developing countries. Multiple cerebral localizations with a cardiac origin are exceptional and are sometimes diagnosed only after onset of complications. We present the case of a 22-year-old male student: the diagnosis of multiple cerebral hydatic cysts caused by rupture of a cardiac hydatic cyst was established after an episode of ischemia of the limbs with cerebral hemorrhage induced by heparin. One year later, the clinical situation consisted in intracranial hypertension, hemiplegia and convulsive seizures. We observed no cardiac symptoms. The brain CT showed 9 hydatic cysts and echocardiography showed a myxomatous cystic tumor. Abdominal CT detected renal and splenic hydatic cysts. The patient underwent total ablation of the cerebral and abdominal cysts and made a full recovery. After surgical removal of the cardiac cyst, the patient has been lost to follow-up. Cerebral hydatidosis of cardiac origin is highly exceptional and, due to nonspecific symptomatology, may go undiagnosed. In general, prognosis is good in case of a cerebral localization but the cardiac localization is associated with high mortality.

We report a case of an epidermoid cyst of the occipital skull vault in a 28 year-old woman. The symptomatology was an occipital swelling and pain. The diagnosis was evoked on the skull X-ray and computed tomography scan. Total removal of the tumor provided complete recovery.

This study reports 7 cases of cervical Pott's disease, gathered during 6 years in the department of neuro-surgery of Ibn Rochd U.H.C. 4 females and 3 males, aged between 9 and 52 years were included. All the patients complained of cervicobrachial pain and weakness of the limbs. Clinical features were: deterioration of general status, rachidian syndrome and neurological impairement with motor and sensitive deficit. Radiological analysis found a destructive and extensive lesion, cervical kyphosis from 10 degrees to 60 degrees, retropharyngeal abscess and intraspinal canal extension of infection. Diagnosis was confirmed by histological study in all cases. In addition to antituberculous therapy and preoperative cervical traction in 4 cases, all the patients had spinal fusion using an anterior approach. Post operative immobilization in a cervical collar varied from 9 to 12 months. All 7 patients had full neurological recovery, 6 patients had an excellent bony fusion and cervical kyphosis was corrected. For the remaining patient, the bone graft was mobilized without neurological disorders. This study confirms anterior arthrodesis efficiency. This procedure in conjunction with preoperative traction, allowed stabilization of the spine and healing of vertebral lesions with excellent kyphosis correction.

Three cases of abdominal catheter migration through the anus following ventriculo-peritoneal shunt are described. Two cases involved hydrocephalus secondary to tuberculous meningitis and the third myelomeningocele. Among the reasons for migration, the length of the abdominal catheter, trauma during the operation and infection must be taken into consideration. One patient was suffering from meningitis at the time of admission, while the two others were asymptomatic. Treatment involved removing the peritoneal catheter in 2 cases and the entire shunt system in the patient with meningitis. The shunt was replaced one to two weeks later. The outcome was favourable in all three cases.
