Outer retinal tubulation and inner retinal pseudocysts in a patient with maternally inherited diabetes and deafness evaluated with optical coherence tomography angiogram

A 47-year-old lady (index case) with diabetes and deafness showed multiple oval circumferential areas of perifoveal atrophy in both eyes. Autofluorescence revealed areas of hypoautofluorescence. Optical coherence tomography (OCT) showed depression of inner retinal surface, inner retinal hyporeflective spaces (pseudocysts), disorganization/thinning of outer retina, outer retinal tubulation, loss of external limiting membrane, ellipsoid and interdigitation zone, and thinning of the retinal pigment epithelium and choriocapillaris. The patient was evaluated using OCT angiogram. Retinal lesions of her mother (68-year-old) were very obvious on autofluorescence imaging. The result of A3243G mutation in MTTL1 gene was positive in the index case confirming the diagnosis of maternally inherited diabetes and deafness (MIDD).

Central retinal arterial occlusion in a patient with pyoderma gangrenosum

A 74-year-old male presented to us with a history of vision loss for 36 hours in the right eye (RE). The RE had a visual acuity of hand movements. The fundus revealed a pale retina, cattle tracking in the retinal vessels, and a cherry-red spot at the macula. The patient was a known case of pyoderma gangrenosum (PG) and had received intravenous methylprednisolone and cyclophosphamide at the onset of visual symptoms. An emergency anterior chamber paracentesis was performed following unsuccessful attempts of ocular massage. The patient improved to 6/9 in the RE 4 months after paracentesis. The patient had an aggressive course of PG, for which he needed a combination of oral steroid, immunomodulator therapy and biologicals. An association between central retinal arterial occlusion and PG has not been reported before, according to the best of authors' knowledge.

Primary tuberculosis of tongue.

Primary tuberculosis of tongue is very rare with unusual presentation creating a diagnostic dilemma. We report a case of primary tuberculosis of tongue in a 49-year-old female patient. Tuberculosis was not suspected clinically and there was no other focus elsewhere in the body. Fine needle aspiration cytology was attempted but was inconclusive. The diagnosis was made after histopathological examination.

Role of garlic (Allium sativum L.) in human and plant diseases.

A resurgence of interest in garlic due to recent revelations of its beneficial effects in the treatment of various human and plant diseases and also due to validation of claims made in traditional systems of medicine has resulted a plethora of publications on different aspects of garlic in recent years. Chemical constituents of garlic and their variations on the methods of isolation have been discussed in the present review. Effect of garlic and its constituents against various human and plant pathogenic and saprophytic microorganisms has also been reviewed.
