A simple method of assessment of gestational age in newborn infants.

A simple method of assessment of gestational age based on only four characteristics, namely, the anterior vascular capsule of the lens, plantar creases, breast nodule, and ear firmness, is presented. Critical evaluation by appropriate statistical analyses has shown this to be a useful method of practical value with 95% confidence limits of 11 days. It is applicable to newborn infants, including sick babies, at any time within the first 2 days of life.

A new treatment of pthiriasis palpebrarum.

Treatment of phthiriasis palebrarum so far is unsatisfactory and prolonged. It was an accidental finding that led us to try various strengths of fluorescein on head lice. It was seen from our study that 20% fluorescein resulted in the lice' instantaneous death. This percentage was used in all our subsequent cases of phthiriasis with excellent results. A new method for the treatment of phthiriasis palpebrarum from the eyelash by a single application of 20% fluorescein is described. This method required no sedation or anesthetic and can be carried out as an outpatient department procedure. It is nontoxic and not irritating. There is no risk of the physician being infested, as the lice and nits are killed instantaneously.

Pulmonary tuberculosis in Ahmedabad: epidemiology, diagnosis and short course chemotherapy.

Five hundred children below the age of 12 years suffering from lung tuberculosis viz., primary complex (PC) or progressive primary complex (PPC) were studied. Diagnosis was based on Kenneth Jones criteria; selected cases having score of 5 or more. One hundred and eighty cases of PC were given A-1 (6 RH) regimen, while 312 cases of PPC were given A-2 (2SHRZ/4 RH) or A-3 (2 SRH/4 RH) or A-4 (2 RHE/4 RH) regimen. Follow-up was done for 6 months after completing the treatment to observe the relapse rate. In cases of PC, 6 RH regimen appeared adequate and cheaper with no relapse rate. In cases of PPC with short course chemotherapy, compliance of patients had been very good. Relapse rate was up to 13% which is acceptable. Drug toxicity was very low.

Posterior continuous curvilinear capsulorhexis with and without optic capture of the posterior chamber intraocular lens in the absence of vitrectomy.

PURPOSE: To evaluate the efficacy of posterior continuous curvilinear capsulorhexis (PCCC) with optic capture of the posterior chamber intraocular lens (PC IOL) in the absence of vitrectomy in preventing secondary opacification of the visual axis following pediatric cataract surgery. PATIENTS AND METHODS: Thirty-four eyes of 28 children with congenital or developmental cataract, aged 1.5 to 12 years (mean, 6.39 years), were included in this prospective, randomized study. Anterior continuous curvilinear capsulorhexis (ACCC) with PCCC without optic capture of the PC IOL was performed in group A (18 eyes) and ACCC with PCCC with optic capture of the PC IOL was performed in group B (16 eyes). None of the eyes underwent anterior vitrectomy. Secondary opacification of the visual axis, visual acuity, and possible complications were observed and analyzed. RESULTS: The follow-up period ranged from 8 to 28 months (mean, 17.5 months). All 16 eyes (100%) in group B had a clear visual axis at the end of follow-up. Eight eyes (44.4%) in group A had significant opacification of the visual axis. The difference between the two groups was statistically significant (P = .0011). No eye in group B required secondary intervention, whereas all 8 eyes in group A with significant secondary opacification required secondary intervention. There was no statistically significant difference in other complications such as anterior chamber reaction, fibrin formation, lenticular precipitates, and posterior synechiae. The final best-corrected visual acuity at the end of follow-up was comparable in the two groups (P > .05). CONCLUSION: PCCC with optic capture of the PC IOL prevents secondary opacification of the visual axis even in the absence of vitrectomy.

Polyglactin sutures versus nylon sutures for scleral flap suturing in trabeculectomy.

BACKGROUND AND OBJECTIVES: To note the effect on filtration function of using polyglactin sutures for scleral flap suturing in trabeculectomy. PATIENTS AND METHODS: Polyglactin sutures were compared with nylon sutures to secure the scleral flap of trabeculectomy in 30 consecutive eyes. Parameters studied were intraocular pressure, central anterior chamber depth, and bleb score in this randomized prospective study. RESULTS: Observations regarding intraocular pressure, central anterior chamber depth and bleb score in the early postoperative period were comparable in the 2 groups. The results at 12 months follow-up reveal a lower mean IOP (P < 0.05) and a higher mean bleb score (P < 0.05) in the group with polyglactin sutures. Success rate (defined as IOP < 21 mm Hg) at 12 months was 100% with use of polyglactin sutures compared to 80% with nylon sutures. CONCLUSIONS: Polyglactin sutures can be used as an alternative to nylon sutures for scleral flap suturing in trabeculectomy, with the possible additional benefit of better long-term filtration function.

Modified grey line split with anterior lamellar repositioning for treatment of cicatricial lid entropion.

To determine the success rate of surgery of modified grey line split with anterior lamellar repositioning in patients with cicatricial lid entropion and to determine the risk factors of failure of the procedure, 40 patients (84 lids) with either lid involvement caused by cicatricial lid entropion of different etiologies were enrolled in this study. All the lids were operated on using the technique of modified grey line split and anterior lamellar repositioning. The success of the procedure was assessed by restoration of anatomical and physiological functioning of the lid without any residual symptom to the patient. Patients were examined initially at weekly intervals for 1 month and subsequently followed up at 2, 3, and 12 months following surgery. Among the various causes for cicatricial lid entropion, infectious etiology (72/84 lids) was found to be the most common one. A success rate of modified grey line split with anterior lamellar repositioning was 88.09% (74/84 lids). The underlying etiology of cicatricial lid entropion was the sole predictor of failure of surgery. Those with the etiology of infection had more than 6 times the odds of surgery failure (OR: 6.73; 95% CI: 2.79-16.73) as compared to a patient without infectious etiology. The role of other factors such as the age of the patient, degree of entropion, previous entropion surgery, the lid (upper or lower) involved, irregular lid margin, and defective lid closure were statistically insignificant. The underlying etiology of cicatricial lid entropion is the only risk factor that significantly influences the outcome of surgery with this technique. Otherwise, this procedure gives good results with fewer complications in patients with cicatricial lid entropion.

Bilateral tubercular lid abscess--a case report.

Tuberculosis is a ubiquitous disease and a public health problem of major importance in almost all countries. The disease can involve any part of the body. Eye involvement to tuberculosis is also common. A case of bilateral tubercular lid abscess without any active systemic involvement is being reported because of its rare occurrence.
