Managing the injury burden in Nepal.

Nepal loses about 530,000 disability adjusted life years (DALYs) per year to injury, predominantly due to falls. It takes 30,000 Nepali rupees (NR), or approximately US$430 at 70 rupees per $US saved per DALY to achieve primary prevention and 6000 NR per DALY if we invest in hospitals, versus 1000 NR invested in prehospital care, because simpler less expensive actions performed early have a greater impact on outcome than more complex measures later. A system for prehospital services was planned for medical emergencies at a national level meeting at the Medical University of Nepal to promote healthcare to victims in inaccessible regions by empowered or enlightened citizens. Feasible actions for common emergencies were defined and a tutorial required to help the majority of such victims was created and packaged. The knowledge and attitude component of the tutorial will be delivered through a web site to citizens motivated to learn and help with emergencies. The knowledge will be tested through a net-based Multiple Choice Questions (MCQ) test. Practical training in medical triage skills will be provided to those who qualify for the test at the University or its designated affiliates. A mobile phone-based information system will be created and used to make these enlightened citizens available to the victim at the site/time of the emergency.

Epidemiologic characteristics, predisposing factors, and etiologic diagnosis of corneal ulceration in Nepal.

Corneal ulceration is one of the most frequent causes of blindness in developing countries. Between September 1985 and August 1987, 405 patients with corneal ulceration were examined at Tribhuvan University Teaching Hospital in Kathmandu, Nepal. Males and females were equally affected. The most common predisposing cause of ulceration was corneal trauma, usually with organic agricultural materials. Microorganisms were grown from 324 (80%) of the ulcers. Pure bacterial cultures were obtained from 256 (63.2%) of the patients, whereas pure fungal cultures were obtained from 27 (6.7%) of the patients. In 41 patients (10.1%), corneal cultures yielded a mixed growth of bacteria and fungi. Of a total of 398 bacterial isolates, 124 (31.1%) were positive for Streptococcus pneumoniae, the most commonly isolated organism in the series. Other frequently isolated bacteria included Staphylococcus epidermidis, S. aureus, and Pseudomonas species. Of 68 positive fungal isolates obtained, 32 (47.0%) were identified as Aspergillus species. Candida species and Fusarium species were less commonly seen.

The Bhaktapur eye study: ocular trauma and antibiotic prophylaxis for the prevention of corneal ulceration in Nepal.

AIMS: To determine the incidence of ocular trauma and corneal ulceration in the district of Bhaktapur in Kathmandu Valley, and to determine whether or not topical antibiotic prophylaxis can prevent the development of ulceration after corneal abrasion. METHODS: A defined population of 34 902 individuals was closely followed prospectively for 2 years by 81 primary eye care workers who referred all cases of ocular trauma and/or infection to one of the three local secondary eye study centres in Bhaktapur for examination, treatment, and follow up by an ophthalmologist. All cases of ocular trauma were documented and treated at the centres. Individuals with corneal abrasion confirmed by clinical examination who presented within 48 hours of the injury without signs of corneal infection were enrolled in the study and treated with 1% chloramphenicol ophthalmic ointment to the injured eye three times a day for 3 days. RESULTS: Over the 2 year period there were 1248 cases of ocular trauma reported in the population of 34 902 (1788/100 000 annual incidence) and 551 cases of corneal abrasion (789/100 000 annual incidence). The number of clinically documented corneal ulcers was 558 (799/100 000 annual incidence). Of the 442 eligible patients with corneal abrasion enrolled in the prophylaxis study, 424 (96%) healed without infection, and none of the 284 patients who were started on treatment within 18 hours after the injury developed ulcers. Four of the 109 patients (3.7%) who presented 18-24 hours after injury developed infections, and 14 (28.6%) of the 49 patients who presented 24-48 hours subsequently developed corneal ulceration. CONCLUSIONS: Ocular trauma and corneal ulceration are serious public health problems that are occurring in epidemic proportions in Nepal. This study conclusively shows that post-traumatic corneal ulceration can be prevented by topical application of 1% chloramphenicol ophthalmic ointment in a timely fashion to the eyes of individuals who have suffered a corneal abrasion in a rural setting. Maximum benefit is obtained if prophylaxis is started within 18 hours after injury.

Congenital isolated bilateral upper lid coloboma.

A case of congenital isolated coloboma of both the upper lids from just lateral to the lacrimal punctum up to the medial half, with symblepharon in the region of lower eyelid, was studied in a 7-year-old female child. She did not have any other associated anomalies. The birth and family histories were normal. The puncta were normal in position and well apposed to the globe. The closure of the lid coloboma was done by release of symblepharon along with direct closure of the defect, for the right eye first, and one month later, for the left eye.

Spontaneous extrusion of subconjunctival cysticercous cyst: a case report.

Ocular cystericosis is the common occurrence among the people of lower socioeconomic status and poor personal hygiene in developing countries. However, spontaneous extrusion of subconjuctival cysticercous cyst is a rare incidence. The present case report describes a spontaneous extrusion of subconjunctival cyst in a 12 year old boy in our clinical set-up. The histopathological examination revealed subconjunctival cysticercous cyst. The extrusion was associated with improvement in clinical sign and symptoms. Cysticercosis should be considered in any case of inflammatory swelling of subconjunctival space especially in people of lower socioeconomic status and poor personal hygiene.

Etiological pattern of blepharoptosis among patients presenting in teaching hospital.

The purpose of this study was to find out the etiological pattern of blepharoptosis among patients presenting in BPKLCOS, T.U. Teaching Hospital. This was a hospital based descriptive and cross-sectional study conducted from February 2003 to July 2004. A total of 125 patients with ptosis were evaluated. 78 cases (62.4%) were congenital and 47 cases (37.6 %) were acquired. Congenital simple ptosis and congenital complicated ptosis comprised of 58% and 42% respectively. Among the acquired cause, ptosis due to trauma was the commonest 32%, followed by third cranial nerve palsy 25.5%, myasthenia gravis 17%, aponeurotic 10.7%, chronic progressive external ophthalmoplegia 8.5% etc. Aetiology-wise, myogenic ptosis was the commonest (65.6%) which was followed by neurogenic (16.8%), traumatic (12%) and aponeurotic ptosis (5.6%). Congenital ptosis is more common than acquired ptosis. Myogenic ptosis is the most predominant type of ptosis. Among the congenital ptosis, congenital simple ptosis is more common than congenital complicated ptosis. Among the acquired cases trauma, third cranial nerve palsy and myasthenia gravis are the major attendees.

An unusual presentation of giant cell tumour (osteoclastoma).

The number of well-documented true giant cell tumours arising in any of the craniofacial bones is small, but they do exist. A 19 year old female, Ms. KS, presented with complain of progressive enlargement of facial bones especially jaw bones, then orbit symmetrically since the age of 7. There was bilateral gross enlargement of mandible, maxilla, orbital walls, causing displacement of eye medially and upwards. The visual acuity of both eyes were 6/36 and 6/18 with best correction. Extra ocular movements were restricted because of bony growth and conjunctiva over inferior fornix were keratinized due to exposure. Fine needle aspiration (FNAC) from the side of bony growth showed plenty of osteoclasts with multinucleated giant cells. The level of serum alkaline phosphatase were highly increased. She underwent orbitotomy and a part of tissue was sent for biopsy which revealed multiples of mononucleargiant cells and tumour cells.
