Elevated maternal serum-free β-human chorionic gonadotropin (β-hCG) and reduced risk of spontaneous preterm delivery*

Objective: To evaluate the relationship between first and second trimester maternal serum-free β-hCG and the risk of spontaneous preterm delivery (PTD).

Study design: This was a case-control study of women evaluated and delivered at our institution from 2011 to 2015. Spontaneous PTD was defined as delivery before 37 weeks due to spontaneous preterm labor or premature rupture of membranes. Patient with multifetal gestation and those with medically indicated term or PTD were excluded.

Results: Of 877 women meeting the inclusion criteria, 173 delivered preterm and 704 delivered at term, and 8.1% had high free β-hCG in one or both trimesters. High maternal first and/or second trimester free β-hCG (≥95th percentile) was associated with lower rates of PTD. Thirty-two women with high free β-hCG in both first and second trimesters delivered at term. Gestational age at delivery and birth weights were lower in women who did not have high free β-hCG in any trimester. Low free β-hCG (≤5th percentile) in either trimester was not associated with an increased or decreased likelihood of PTD. Logistic regression demonstrated an independent association of high free β-hCG (≥95th percentile) with a reduced likelihood of PTD. Stratified analysis revealed a stronger impact of this association in women with no prior history of PTD.

Conclusions: High free β-hCG, in the absence of risk factors for medically indicated PTD, is associated with a reduced likelihood of spontaneous PTD and may represent a marker indicating lower risk.     

First report of Mortierella wolfii causing fungal keratitis from a tertiary eye hospital in India

A young 33 year old male presented with non-resolving corneal infiltrate for 2 month duration in the right eye. KOH/ Calcoflour wet mount revealed sparsely septate fungal hyphae. Post therapeutic penetrating keratoplasty 3 doses of intracameral voriconazole(100μg/0.1ml) was administered suspecting recurrence. Fungal culture revealed non sporulating mould on SDA. PCR based DNA sequencing targeting the ITS region identified the fungal isolate as Mortierella wolfii (M. wolfii) belonging to zygomycetes. To the best of our knowledge, this is the first report of human fungal keratitis caused by M. wolfii.     

The Global Educational Toxicology Uniting Project (GETUP): an Analysis of the First Year of a Novel Toxicology Education Project

The international boundaries to medical education are becoming less marked as new technologies such as multiuser videoconferencing are developed and become more accessible to help bridge the communication gaps. The Global Educational Toxicology Uniting Project (GETUP) is aimed at connecting clinicians in countries with established clinical toxicology services to clinicians in countries without clinical toxicologists around the globe. Centers that manage or consult on toxicology cases were registered through the American College of Medical Toxicology website via Survey Monkey®. Data was analyzed retrospectively from February 2014 to January 2015. Google hangouts® was used as the main conferencing software, but some sites preferred the use of Skype®. Registration data included contact details and toxicology background and qualifications. Thirty sites in 19 different countries in Australasia, Europe, Africa, and America were registered. Twenty-eight (93 %) sites were located in a major urban center, one (3.5 %) site in a major rural center and one (3.5 %) a private practice. Expectations of GETUP included sharing toxicology cases and education (30, 100 % of sites), assistance with toxicology management guidelines (2, 7 %), assistance with providing a toxicology teaching curriculum in languages other than English (2, 7 %), and managing toxicology presentations in resource-poor settings, international collaboration, and toxicovigilance (2 sites, 7 %). Twenty-two conferences were performed during the first 12 months with a mean of 3 cases per conference. GETUP has connected countries and clinical units with and without toxicology services and will provide a platform to improve international collaboration in clinical toxicology.     

Pigment dispersion syndrome diagnosed after photorefractive keratectomy—A case report

Pigment dispersion syndrome predominantly affects young myopes. It is not uncommon for such patients to seek refractive surgery. It may also be encountered after an uneventful refractive surgery. We report a case of a young myopic male who presented with bilateral pigment dispersion syndrome 9 months after an uneventful photorefractive keratectomy. A meticulous ocular examination is the cornerstone of a successful refractive surgery. Through this report, we highlight the need for gonioscopy to be included as a routine examination in screening for refractive surgery.     

Miniarthrotomy assisted percutaneous screw fixation for displaced medial malleolus fractures – A novel technique

Aim

To describe here a technique of miniarthrotomy assisted percutaneous screw insertion for displaced Herscovici type B and C medial malleolar fractures.

Method

Incision was made centred over the superomedial angle of the ankle mortise, about half a cm medial to tibialis anterior. Arthrotomy was done and reduction obtained. Percuntaneously, two 4 mm cancellous cannulated screws were inserted through medial malleolus.

Results and conclusion

This approach allows direct visualization of reduction, removal of entrapped soft tissue and preservation of saphenous vein and nerve.
