ABSTRACT
Background: Atrial fibrillation (AF) is the most common arrhythmia requiring treatment. High-dose oral anti-arrhythmics (mainly class 1C or quinidine) are used as “pill in the pocket” approach to convert recent onset AF. However pro-arrhythmic risk has limited the application of this approach in many patients. Ranolazine, an antianginal agent, which inhibits abnormal late Na+ channel currents, decreases sodium-calcium overload, potentially inhibits after-depolarisations which have been implicated in the initiation and propagation of AF. Methods: Two gramme ranolazine was given orally to 40 patients with new (first detected episode of AF, 16 patients) or paroxysmal (3 hours to 72 hours duration, 24 patients) AF. Twenty-four patients were in hospital, 6 in office, and 10 at home at the time of ranolazine administration. Age, sex, associated health condition, structural heart disease (SHD) and echocardiographic criteria were recorded. Treatment for other related conditions was also given. Successful conversion was defined as restoration of sinus rhythm within 6 hours of ranolazine administration. Results: Twenty-six of 40 patients (65%) converted to sinus rhythm. No pro-arrhythmic effects, haemodynamic instability, adverse effects, or perceived intolerance were noted. Conclusion: High-dose oral ranolazine shows utility as a possible safe agent to convert new or paroxysmal AF.

Sixty consecutive patients having multibacillary leprosy were examined for symptoms of nasal involvement and sinusitis. A complete ENT examination was carried out of all these patients and they were subjected to radiological examination of paranasal sinuses. Radiological abnormalities of maxillary antrum were found in 15 of 20 cases of lepromatous leprosy, 6 of 26 cases of borderline lepromatous and in 14 cases of mid-borderline leprosy. Localized or generalized mucosal thickening was the most common finding, followed by opacity of maxillary antrum. Radiological abnormalities were confirmed by antroscopy, which is the most appropriate technique for making an accurate diagnosis of maxillary antral diseases. Initially, antral involvement may begin with a localized area of mucol erythema, progressing to a typical granuloma formation and ulceration. The antero-inferior part of the antrum was found to be the most commonly affected region.

Two antral biopsies each from 104 patients of leprosy and 100 controls were studied to find out the prevalence of H. pylori and associated histopathological changes. Sections were stained with hematoxylene and eosin, AB/PAS (Ph 2.5) and Loeffler's methylene blue stains. Infection by H. pylori, inflammation and atrophy were found to be significantly more in leprosy patients as compared to controls (p < 0.01, < 0.005 and < 0.02 respectively). On comparing the histopathological changes in various subgroups of leprosy, H. pylori, inflammation and activity showed a statistically decreasing trend from tuberculoid to lepromatous subgroups (p < 0.05, < 0.001, < 0.01 respectively). Atrophy showed a significant increasing trend from tuberculoid to lepromatous group (< 0.001), it is concluded that despite a low prevalence of H. pylori and associated gastritis in patients with lepromatous leprosy, gastric epithelial damage is more marked due to altered immune response.

Dermatitis artefacta is an uncommonly encountered condition. This paper presents a case report of two such rare patients. The symptomatology and history of fourteen and sixteen year old males with dermatitis artefacta are described. Possible psychophysiological aetiology of the cases is discussed.

The study included 53 patients of untreated leprosy attending University Hospital, Banaras Hindu University during study period of 1 1/2 years. The various types of leprosy included 9,14,16 and 14 cases of tuberculoid, borderline, lepromatous and leprosy with type II reaction respectively. Majority of the patients were below the age of 49 years with male preponderance. 66.04% of patients came from the rural area. Painful micturation (dysuria) (13.20%) was the commonest urinary complaint recorded on enquiry. Specific gravity of urine did not show any change. Abnormal proteinuria was noted in 16.98%, 11.32%, 7.54% and 3.77% of patients of leprosy with reaction, lepromatous, borderline and tuberculoid group respectively. Significant haematuria, pyuria and epithelial cells were noted in all the groups. Haematuria was recorded in focal segmental Glomerulonephritis (GN), mesangioproliferative and diffuse endocapillary Glomerulonephritis (GN) incidence of which was 7.89%, 7.89% and 5.26% respectively in the biopsy tissue. Significant pyuria was noticed in all the groups except minimal change GN.
