Longus Colli Tendinitis: The Lost Twin of Retropharyngeal Abscess.

Longus colli calcific tendinitis is a rare condition which mimics the alarming condition, retropharyngeal abscess. Clinically, the patient presents which acute cervical pain, dysphagia and fever. Since this condition is little known to otorhinolaryngologists, it is usually misdiagnosed as a retropharyngeal abscess which is more common. This is a case report of a 52 year old female who presented with complaints of neck pain and difficulty in swallowing along with fever which were acute in onset. Clinically, the symptoms overlapped with those of a retropharyngeal abscess. The diagnosis was confirmed as longus colli calcific tendinitis. Longus colli calcific tendinitis is a rare entity which can be diagnosed solely based on radiological investigation. The knowledge of this disease is crucial to otorhinolaryngolists as it avoids over treatment, unwarranted chance surgical exposure.

A Rare Malignant Transformation of an Ovarian Cystic Teratoma: A Case Report.

Mature cystic teratoma (MCT) is the commonest germ cell neoplasm of the ovary but malignant transformation is a rare occurrence (1-2%). Of these malignancies documented in literature the commonest are squamous cell carcinoma and adenocarcinoma. Urothelial carcinomas arising in an MCT are a rare occurrence and only 7 cases have been reported in literature. We report a case of an MCT which was complicated by the presence of urothelial carcinoma confirmed on histopathological examination.

Quantitative expression analysis of drought responsive genes in clones of Hevea with varying levels of drought tolerance.

In order to meet the ever rising global demand for natural rubber, cultivation of Hevea is being extended to non-traditional regions of India where extreme climatic conditions like drought and low temperature negatively influence the crop performance. In order to ensure maximum productivity, identification of drought tolerant clones of Hevea which can cope up with stress and give better crop yield is essential. Several attempts have been made previously to identify genes that are associated with drought tolerance in Hevea. In the present study, quantitative expression analysis was made using quantitative PCR for seven drought associated transcripts in four clones of Hevea with varying levels of drought tolerance. Among the seven genes studied, Mitogen Activated Protein (MAP) kinase, Myeloblastosis (Myb) transcription factor, C-repeat responsive element/Dehydration Responsive Element (CRT/DRE) binding factor and Nuclear Factor Y subunit A (NFYA) showed a positive association with drought tolerance. Transcripts of ascorbate peroxidase and heat shock protein 70 (HSP 70) did not show any correlation with drought tolerance. Interestingly, catalase gene was found down regulated in all the clones under drought condition. The possible role of these genes based on their level of gene expression in four different clones of Hevea with varying levels of drought tolerance is discussed.

Benign enlargement of sub-arachnoid spaces in infancy.

Benign enlargement of sub-arachnoid spaces (BESS) is one of the causes of macrocephaly in infants. It is a self-limiting condition and does not require any active medical or surgical treatment. We report a case of an infant aged 4 months who was referred for magnetic resonance imaging (MRI) of the brain as the head circumference of the infant had increased rapidly from the 50(th) percentile in the 3(rd) month to more than the 95(th) percentile in the 4(th) month of age. MRI revealed enlarged anterior sub-arachnoid spaces and mild prominence of all the ventricles. A possibility of BESS was suspected since the child was neurodevelopmentally normal. A follow-up MRI done at the age of 18 months showed a reduction in the size of the sub-arachnoid spaces with normal sized ventricles.
