Safety and efficacy of early amino acids in preterm <28 weeks gestation: prospective observational comparison.

OBJECTIVE: To assess the safety and efficacy of early amino acid (AA) administration in preterm neonates <28 weeks gestational age. STUDY DESIGN: Prospective data collection for 1 year for the late AA group (AA started at 12-30 h) and for another year with practice change to early AA administration (immediately after stabilization). RESULTS: Time of initiation of AA differed (early group 4+/-3 h vs late group 20+/-6 h; P<0.001). There were no statistically significant differences in the incidence of clinically significant metabolic acidosis. Blood urea at 24 h was higher in the early AA group. No significant differences in growth rate or neonatal outcomes were identified. Days to regain birth weight and sepsis were lower in the early AA group. CONCLUSIONS: Early AA administration was not associated with any clinically significant adverse effects; it was associated with reduction in the incidence of sepsis and marginally effective in reducing time to regain birth weight.     

Experience with the International League Against Epilepsy Classifications of Epileptic Seizures (1981) and Epilepsies and Epileptic Syndrome (1989) in Epileptic Children in a Developing Country

Four hundred eighty-three epileptic children attending the Pediatric Epilepsy Clinic at Bai Jerbai Wadia Hospital for Children, Bombay, India were classified according to the International League Against Epilepsy (ILAE) classification of epileptic seizures (1981) and epilepsies and epileptic syndromes (1989). The predominant seizures were partial (53.6), generalized (40.3%), and unclassifiable (6%). In epilepsies and epileptic syndromes, 55.3% were partial, 27% were generalized, 13.5% were undetermined, and 4.1% were special syndromes. Although our results were similar in many respects to those of other reported series, some differences were observed in the incidence of partial and generalized seizures, and partial and generalized epileptic syndromes and their subgroups, such as idiopathic, symptomatic, and cryptogenic partial syndromes, idiopathic generalized syndromes, and symptomatic specific syndromes. These differences are probably due to different age limits, methods of case ascertainment and inclusion criteria, different genetic and environmental factors, variable interpretation of clinical and EEG features, and lack of facilities for investigation in developing countries. Despite various limitations, we were able to classify most cases; the ILAE classification can be used in developing countries so that comparison can be made with other studies.     

Endoscopic pituitary surgery - a. beginner’s guide

Endonasal endoscopic surgery is now the preferred technique to tackle pituitary tumours. Our paper describes the stepwise endoscopic approach for surgeons embarking on pituitary surgery. It also highlights the common pitfalls encountered during surgery and the ways to avoid them. One must proceed in a gradual step- wise manner starting from simple exposure of the sphenoid sinus to complete endoscopic tumour removal so us to gain the neurosurgeon’s confidence as well as develop our own skills, confidence and ability to tackle complications. We use the endonasal paraseptal trans- sphenoidal approach. Surgery begins with gentle packing between the middle turbinate and septum to expose the anterior sphenoid wall and expose the sphenoid astium. The ostitum is then widened inferiorly and onto the opposite side to expose both sphenoid sinuses. The inter- sphenoid sinus and necessary mucosa is removed to expose the sella. We then use a bone flap technique or punches to open the sella. After incising the dura, tumour is removed with a suction curette. An endoscope holder facilitates the operation. The bone flap is replaced at the end of surgery to reconstruct the sella. This is especially important if a CSF leak is present. Nasal packing is usually not required.     

Implications of sub-specialisation on the waiting times of general surgical clinics.

INTRODUCTION: Controversy around sub-specialisation in a district general hospital (DGH) has been ongoing for years. AIM: To study the effect of colorectal sub-specialisation on general surgical cases. METHODS: A retrospective audit between October 2002 and September 2003, including all referrals to the outpatient clinics of a single consultant surgeon in a DGH. RESULTS: 1,055 patients were seen in outpatient clinics, of which 53% (563) were seen in rapid access colorectal clinics. Overall, 87% (914) of patients were diagnosed to have colorectal pathology. The majority of the colorectal cases were referred using the designated referral forms. There were 427 urgent, 162 soon and 325 routine referrals with colorectal pathology, and 35 urgent, 22 soon and 84 routine referrals with non-colorectal pathology. Median waiting times for urgent, soon and routine referrals were 12, 61 and 91 days, respectively, for patients with colorectal pathology, in comparison with 44, 75 and 397 days for non-colorectal pathology. CONCLUSION: This audit confirms that colorectal sub-specialisation has resulted in a significant delay in the management of patients with non-colorectal diseases. This has major implications within a DGH setting.     

Multiple intramedullary lipomas with conal intramedullary dermoid: magnetic resonance appearances.

BACKGROUND CONTEXT: Intramedullary fat-containing benign childhood tumors of the cord include lipomas, dermoid cysts, and teratomas. These are embryonal tumors. Most intramedullary fat-containing tumors are solitary. Multiple intramedullary lipomas are rare and may represent a spinal lipomatous malformation. The presence of another intramedullary dermoid tumor in the same case is rare. PURPOSE: The intent of this case report is to look at magnetic resonance features and possible mechanisms of association of these fat-containing intramedullary tumors. STUDY DESIGN/SETTING: A 3-year-old male child presented with spastic quadriplegia. METHODS: Magnetic resonance imaging (MRI) of spine was done on a 1.5-T scanner in different planes. RESULTS: MRI showed multiple intramedullary spinal lipomas with an intramedullary dermoid involving the conus, cord atrophy, and subarachnoid fat droplets. CONCLUSION: Multiple intramedullary lipomas with an intramedullary dermoid represent a form of spinal lipomatous malformation. Both may represent embryogenic mesenchymal inclusions and hamartomatous growth, which can be accurately diagnosed with MRI.
