Psychiatric polypharmacy refers to the prescription of two or more psychiatric medications concurrently to a patient. It can be categorised as same-class, multi-class, adjunctive, augmentation and total polypharmacy. Despite advances in psychopharmacology and a better understanding of the principles of therapeutics, its practice is increasing rapidly. The prevalence of polypharmacy in psychiatry varies between 13%-90%. There are various clinical and pharmaco-economic factors associated with it. Dealing with polypharmacy requires an understanding of its associated factors. Education, guidelines and algorithms for the appropriate management of various conditions are effective ways to avoid irrational polypharmacy.

Growing skull fracture is a rare complication of skull fracture and remains almost undetected in the first few years of life. Here, we report a series of 11 patients with growing skull fracture treated at our institute over a period of five years and discuss their clinical features, radiological findings, and principles of management. Of the 11 patients, six were females and five males, with the age ranging between 9 months and 12 years (mean, 3 years). Progressive scalp swelling was the most common presenting feature. Other clinical features included generalised tonic clonic seizures, eyelid swelling, and proptosis. Computed tomography scan of the head defined the growing skull fracture in all 11 patients and detected the underlying parenchymal injury. Postoperatively, all patients had a complete resolution of the scalp swelling. Two patients had postoperative seizures and one had cerebrospinal fluid leak. Early recognition and surgical repair is essential to prevent the development of neurological complications and cranial asymmetry.

Dolichoectasia of vertebrobasilar artery is a condition in which the vertebral/basilar artery is elongated, distended and tortuous. It is usually asymptomatic. It may present with compressive or ischemic symptoms. Hydrocephalus as a complication of vertebrobasilar dolichoectasia is rare. We present a case of a 60-year-old male with dolichoectasia of the basilar artery causing compression of the third ventricular outflow and, thus, presenting with noncommunicating hydrocephalus.

Colloid cysts are cystic lesions located at the anterior part of third ventricle, close to foramen of Monro and contain colloid material. Hemorrhage in a colloid cyst is very rare. On literature review, we found only six cases of hemorrgic colloid cyst; among them, four were diagnosed at postmortem examination. We report a rare case of a hemorrhagic colloid cyst in a young lady who presented with sudden onset severe headache and vomiting. Computed tomography (CT) scan showed isodense lesion located at foramen of Monro with hyperdense areas suggestive of hemorrhage with foraminal obstruction. The lesion was not enhancing on contrast. Magnetic resonance imaging (MRI) brain revealed a well-defined cystic mass lesion located at the foramen of Monro which was hyperintense on T1 and hypointense on T2-weighted images. Excision of the colloid cyst was performed which revealed hemorrhagic clot instead of colloid material. Histopathological examination revealed a colloid cyst with hemorrhage. We believe that this is the first such reported case of successful clinical outcome following early diagnosis and excision of a hemorrhagic colloid cyst in an adult.

The Currarino triad, also known as the "Currarino Syndrome", is a rare complex of congenital caudal anomalies including three main features; a sacral bony deformity, anorectal malformations, and a presacral mass. We present an extremely uncommon case of Currarino syndrome in adulthood presenting with repeated episodes of meningitis. Magnetic resonance imaging of spine was suggestive of caudal regression. Cord was low lying, conus ending at L3 level with evidence of tethering at that level. A large cyst was noted in the sacral canal extending forwards in the pelvis through the widened sacral foramina on right side. She was operated through a posterior approach, via sacral laminectomy. Dura was opened in the midline, large silvery white epidermoid tumor was found completely occupying the anterior sacral meningocele. The case and relevant literature is discussed.KeywoRds: Anterior sacral meningocele, Currarino syndrome, Epidermoid cyst, Meningitis ÖZ "Currarino Sendromu" olarak da bilinen Currarino triadı üç ana bulgudan oluşan nadir bir konjenital kaudal anomali kompleksidir: sakral kemik deformitesi, anorektal malformasyonlar ve presakral kitle. Erişkin bir hastada tekrarlanan menenjit episotlarıyla ortaya çıkan çok nadir bir Currarino sendromu vakası sunuyoruz. Omuriliğin manyetik rezonans görüntülemesi kaudal regresyon düşündürdü. Kord düşük seviyedeydi ve konus L3 seviyesinde sonlanıp o seviyede tutunma bulguları gösteriyordu. Sakral kanalda sağ tarafta genişlemiş sakral foramenler içinden pelvise ileri doğru uzanan büyük bir kist görüldü. Hastaya posterior yaklaşımla sakral laminektomi yoluyla ameliyat yapıldı. Dura orta hatta açıldı ve anterior sakral meningoseli tamamen dolduran büyük bir gümüş beyazı epidermoid tümör bulundu. Vaka ve ilgili literatür tartışılmaktadır.ANAHTAR sÖZCÜKLeR: Anterior sakral meningosel, Currarino sendromu, Epidermoid kist, Menenjit
