Walker Malformation

Introduction: Dandy-Walker Malformation is an inborn condition that includesthe triumvirate of cystic enlargement of the fourth ventricle, posterior fossa distension with riseof the tentorium and agenesis of cerebellar vermis. The purpose of this study is to determinethe Clinical presentation and associated complications, mortality and morbidity of patientundergoing placement of shunt with Y- connector in Dandy Walker Malformation. StudyDesign: Case Series comprised of 85 cases. Setting: Neurosurgery Ward of Tertiary CareHospital in Karachi. Period: February 2011 to December 2015. Methodology: All patients whowere presented in OPD with complaints reminiscent of DWM with accompanied Hydrocephalusand then underwent CT scan Brain without contrast to confirm the diagnosis were admitted.The patients who have previous history of operation and other co-morbid anomalies wereomitted. These patients undergo drainage of Ventricular system and Posterior Fossa cyst wasdone mutually via Dual Shunt including Ventricular-peritoneal and Cysto-peritoneal shunt withY connector. There were few complications and mortality after this surgical intervention whichwas noted for a month. All records were recorded and evaluated by SPSS v.20. Result: Avast majority of patients included were Female. The average age of patients was 2.5 years+/- 1 Standard Deviation. The chief complaint was Hydrocephalus, existing in all patients,after that cerebellar signs in 55 (64.7%) and other signs in 10 (11.8%) patients. Others signsincludes; milestones were delayed, atypical gait and few patients were suffered from psychiatricproblems. Complications which were observed were shunt; Fracture/Dislocation in 10 (11.8%),shunt blockage in 8 (9.4%), malpositioning is also 8 (9.4%), Intracranial Hemorrhage in 7(8.24%) patients and Infection in 10 (11.8%). These complications were observed within amonth of surgery. Unfortunately, two (2.35%) patient were also expired after surgical approach.Conclusion: It is concluded that Dandy Walker Malformation is categorized by a triumvirate.Hydrocephalus is a most common symptom and principal cause of referral to hospitals. Thecommonest difficulty acknowledged after shunting is Malfunction and shunt infections. Thelowest mortality is related to Dual Shunt with Y connector when compared to other approachesfor management of shunt with Y-connector. Thus, it is found to be a worthy decision in givenDWM patients.

A Dandy-Walker malformation is an anatomical triad characterized by a large posterior fossa, agenesis of the cerebellar vermis, and dilation of the 4th ventricle. Up to 90% of patients will have hydrocephalus secondary to obstruction of fourth ventricular outflow through the foramen of Luschka and Magendie. The differential diagnosis of Dandy-Walker malformation includes Blake’s pouch cyst, a cystic structure originating within the roof of the 4th ventricle that herniates into the cisterna magna, and posterior fossa arachnoid cysts, which typically displace both the cerebellum and 4th ventricle anteriorly and demonstrate a propensity to enlarge. Brain MRI is the best diagnostic imaging modality to evaluate posterior fossa anatomy and cystic structures. Not all posterior fossa cysts require treatment. Indications for surgical intervention include enlargement, symptomatic mass effect and/or hydrocephalus.

Walker Malformation

Abstract OBJECTIVE AND IMPORTANCE Dandy-Walker malformation has conventionally been managed with placement of cystoperitoneal or ventriculoperitoneal shunts. However, associated aqueductal obstruction requires simultaneous drainage of both the supratentorial and infratentorial compartments. CLINICAL PRESENTATION Three children with Dandy-Walker malformation and aqueductal obstruction were managed with endoscopic third ventriculostomy and placement of a stent from the third ventricle to the posterior fossa cyst. INTERVENTION After an endoscopic third ventriculostomy was performed, the stent was placed from the third ventricle to the posterior fossa cyst through the thinnest part of the posteroinferior wall of the aqueduct. There was no operative morbidity. In one patient, the stent was malpositioned, requiring a repositioning. The endoscopic third ventriculostomy was successful in two patients, whereas it failed in one, requiring a ventriculoperitoneal shunt placement. CONCLUSION Cystoventricular stent placement with endoscopic third ventriculostomy is a promising alternative in patients with Dandy-Walker malformation with aqueductal obstruction.

Imported malaria has increased in Colombia since 2015 and has been attributed to migrants coming from Venezuela. We present a series of malaria cases, nested in a retrospective cross-sectional study between 2017 and 2018, aimed at calculating the prevalence of medical diseases among immigrants in a University Hospital in Colombia. Among 154 immigrants admitted for medical causes between 2017 and 2018, 8 were diagnosed with malaria, all due to Plasmodium vivax. Of these, seven had uncomplicated malaria, five had a previous history of malaria, one was critically ill, but none died. We highlight that, similar to other case series of imported malaria, Latin American migrants were young, with similar clinical profiles, having a low proportion of severe cases, and P. vivax was the most frequent cause.

Introduction: Dandy Walker malformation (DWM) is characterized by agenesis or hypoplasia of the cerebellar vermis, cystic dilatation of the fourth ventricle leading to an increase of the posterior fossa and superior dislocation of the lateral sinus, tentorium and torcula. Although it is the commonest posterior fossa malformation, its pathogenesis is still not fully understood, making the differential diagnosis with other posterior fossa malformations difficult and as a result the choice of therapeutic strategy. Material and methods: An extensive review of the literature relating to Dandy Walker malformation was performed. Historical, genetic, embryologic, epidemiologic, clinical and radiological presentation, treatment and prognosis were revised. Conclusion: The correct diagnosis of Dandy Walker malformation can be made through careful interpretation of magnetic resonance imaging (MRI) and cerebrospinal fluid (CSF) flow studies.  The choice of hydrocephalus treatment depends on whether there is aqueduct stenosis.  And, although ventriculoperitoneal (VP) shunts have been the treatment of choice for many years, neuroendoscopic techniques such as endoscopic thirdventriculostomy and stent placement are being frequently performed lately.

Purpose. Xeroderma pigmentosum (XP) is a rare autosomal recessive genetic disorder characterized by increased susceptibility to UV radiation- (UVR-) induced skin pigmentation, skin cancers, ocular surface disease, and, in some patients, sunburn and neurological degeneration. Eight different genes are affected, and the prevalence of the disease differs across the world. The present study describes the main ophthalmologic features and symptoms in patients with XP in this case series. Methods. Patients were examined consecutively at the University Hospital of the Federal University of Goias between January 2016 and June 2018. All patients underwent ophthalmologic examination and were asked about their ophthalmological history and the presence of ocular symptoms. Results. Twenty-one patients with genetic confirmation were evaluated. The genetic variants XPV and XPC were detected in the patients. The most prevalent findings include eyelid changes, observed in 80.9% of the patients, and ocular surface changes as punctate keratopathy, occurring in 16 patients (76.2%), corneal neovascularization, and corneal opacities. Six patients (28.5%) presented corneoconjunctival tumor. More than half of patients had previous history of treatment of ocular neoplasia. Ocular burning was the most reported symptom. Conclusions. The ocular characteristics identified in this study corroborate the existing literature, mainly related to the surface. Concerning the XP variant and the gravity of ocular signs, XPC has earlier and more severe symptoms than XPV. Due to their relative rarity, publications of XP cases are important to understand the possible damages caused by the disease in the eyes and surrounding area.

Successful Prevention

In recent years an increase in premature births (PB) rate has been noticed, as this pregnancy complication that still remain an important cause of perinatal morbidity and mortality, is multifactorial and prediction is not easy in many cases. There are many bibliographic data supporting the view that PB have also genetic predisposition. The trend of “recurrence” of PB in women as well as its increased frequency in ethnic groups suggests its association with genetic factors, either as such or as an interaction of genes and environment. Immunomodulatory molecules and receptors as well as polymorphisms of various genes and/or single nucleotides (single nucleotide polymorphisms, SNPs) now allow with advanced methods of Molecular Biology the identification of genes and proteins involved in the pathophysiology of PB. From the history of a pregnant woman, the main prognostic factor is a previous history of prematurity, while an ultrasound assessment of the cervix between 18 and 24 weeks is suggested, both in the developed and the developing world. According to the latest data, an effective method of successful prevention of premature birth has not been found. The main interventions suggested for the prevention of premature birth are the cervical cerclage, the use of cervical pessary, the use of progesterone orally, subcutaneously or transvaginally, and for treatment administration of tocolytic medication as an attempt to inhibit childbirth for at least 48 hours to make corticosteroids more effective. Despite the positive results in reducing mortality and morbidity of premature infants, the need for more research in the field of prevention, investigation of the genital code and the mechanism of initiation of preterm birth is important.

Incisional hernia is the second most common type of hernia. Incisional hernia occurs in 10-20% of patients who were subjected to abdominal surgery in India. Here we are presenting a case series of 20 patients with incisional hernia and obesity. Body mass index (BMI) ranges from 28 to 35 in all cases. Females outnumbered the male in the ratio of 4:1 and 40% of cases had a previous history of caesarean section. All cases were operated by combining open polypropylene meshplasty and abdominoplasty techniques and follow up consultations were done for 1 year. 10% of cases had post-op wound infections, who were known to be diabetic. They were managed with appropriate antibiotics and maintained strict glycemic control. 90% of patients were satisfied from the procedure performed which improved their quality of life, significant cosmetic outcome and no recurrence. 10% of cases had recurrence after heavy weight lifting following surgery (BMI was 36). By incorporating the above mentioned techniques in hernia repair, recurrence rate and complications were reduced, quality of life and aesthetic outcome are enhanced.
