Verrucous carcinoma of larynx

A 55 years male presented with hoarsness of voice (4 months), cough (1 month), difficulty in breathing (15 days). Patient underwent an emergency tracneostomy and further workup proved it to be a case of verrucous carcinoma of larynx. Patient was treated surgically with satisfactory result.     

Efficacy of lycopene in the management of oral submucous fibrosis.

OBJECTIVES: To evaluate the efficacy of oral lycopene therapy in patients with oral submucous fibrosis and to compare these effects with a placebo. STUDY DESIGN: Fifty-eight patients with oral submucous fibrosis formed the population for the study and were randomly divided into 3 groups, evaluated weekly over a 2-month period. Patients of group A (n = 21) received 16 mg of lycopene, those of group B (n = 19) received 16 mg of lycopene along with biweekly intralesional steroid injections, and those of group C (n = 18) were given a placebo. Paired and unpaired t tests were used for statistical evaluation. RESULTS: Mouth-opening values for the patients showed an average increase of 3.4 mm, 4.6 mm, and 0.0 mm for patients in groups A, B, and C, respectively. These values were statistically found to be highly significant. CONCLUSIONS: The observed effects suggest that lycopene can and should be used as a first line of therapy in the initial management of oral submucous fibrosis.     

Adult Wilms' tumor: report of a case and review of the literature

A 48 year old male presented with a one and a half year history of a progressively increasing, asymptomatic lump in the left hypochondrium and no history of hematuria. His general physical examination was unremarkable, and an abdominal examination revealed a large, firm, irregular and tender mass in the left hypochondrium extending into the lumbar region. Chest X-ray was normal. An intravenous urogram revealed a normally functioning right kidney with non-visualization of the left kidney. CT-scan of the abdomen revealed a large, mixed attenuating mass replacing the left kidney. At laparotomy, a large, fleshy, well-encapsulated tumor was found in the left kidney with no surrounding infiltration and a left radical nephrectomy was performed. Microscopic examination revealed a poorly differentiated tumor comprised of small round cells with focal areas of abortive embryonal tubular and glomerular differentiation suggestive of Wilms' tumor. The patient was advised chemotherapy and radiotherapy but he absconded and was lost to follow-up.     

"Occult" Boerhaave's syndrome

Spontaneous rupture of the esophagus (Boerhaave's syndrome) usually presents in a dramatic fashion. Classically, following repeated episodes of vomiting, patients present with chest pain, dyspnea, cyanosis, shock, and cardiovascular collapse. We present a case of occult Boerhaave's syndrome diagnosed by an upper gastrointestinal series in a 33-year-old man who arrived at the emergency department with a chief complaint of hematemesis. This case report reviews the usual presenting signs and symptoms of Boerhaave's syndrome and concludes with a caution to physicians not to ignore the possibility of this disease entity in relatively stable patients.     

Preserved vision in a case of morning glory syndrome: some pertinent questions

Morning glory syndrome, an unusual developmental anomaly of the optic nerve head, presenting with funnelled enlargement of the disc with a white dot in the centre and a peripheral vascular pattern along the disc margin, with features of typical entry and exit of retinal vessels on the optic nerve head and exceptionally good vision in the involved eye with old traumatic retinal detachment in the other, in a young Indian girl is described here for its rarity and indifferent clinical presentation. Various factors in its pathogenesis are postulated.     

Aminophylline targeting to lung: optimization of the size and drug loading of albumin microspheres.

Aminophylline, a bronchodilator, was considered a suitable drug for targeting to the lung to treat emphysema. Factorial concept was utilized to optimize the size and drug loading of microspheres suitable for targeting. Aminophylline-loaded albumin microspheres were prepared by heat denaturation adjusting the manufacturing variables, namely albumin concentration, drug concentration, water-oil phase ratio and stirring rate at low and high levels. For two levels of the four variables the experimentation was performed in 16 batches. A good yield of well-defined microspheres of the size range, 2-30 microns, were obtained from all the batches. The drug loading was found maximum (36.33 per cent) in batch XV of microspheres prepared with low albumin concentration, high drug concentration, low water-oil phase ratio and low stirring rate. The least number (13 per cent) of microspheres of batch XV were below 7 microns and the remaining 87 per cent were above this size. Considering the payload and size, microspheres of batch XV were found suitable for targeting to the lung.     

Papillary adenoma of type 2 pneumocytes

A case of papillary adenoma of type 2 pneumocytes is reported. A 57-year-old man had an unusual coin lesion in the periphery of the right lung without any symptoms. When detected in a mass survey examination, it was approximately 1.5 cm in diameter, well circumscribed, and located in S4, involving the sixth-order bronchus of B4. Light-microscopic examination revealed cuboidal tumor cells arranged in a papillary pattern. Ultrastructurally, the cells had characteristic osmiophilic lamellar bodies. By immunoperoxidase staining, the tumor cells were shown to have intracytoplasmic surfactant apoproteins. The postoperative course was uneventful, and there is no evidence of disease 8 years later.
