A Prospective Study on Mycology of Eye Infection in a Tertiary Care Teaching Hospital

Background: Objectives: Fungi are commonly found in the environment and most of them are either commensals or nonpathogenic. Eye infections are caused by bacteria, viruses and less commonly by fungi, therefore not given much attention by the practitioners and also by ophthalmolog ists. In the last one - decade incidence of fungal eye infections has increased due to increase in the number of patients with poor immunity. Common conditions which impair the immunity are prolonged use of steroids and antibacterial broad - spectrum antibioti cs, use of immunosuppressive drugs in cancer patients, in patients with organ transplant and some infections like AIDS. Candida, Fusarium and Aspergillus are the fungi frequently found to be associated with fungal eye infections. Trauma is the most signifi cant predisposing factor particularly when accompanied by contamination with vegetable matter. Methods: Samples such as corneal scrapings, Conjunctival swab, Vitreous & Aqueous aspirates were collected aseptically and sent to microbiology laboratory for KO H wet mount examination and fungal culture. KOH preparation was examined directly under microscope and culture were done on SDA, incubated at 25° c for three weeks. Results: Males were more commonly infected (66.5%) as compared to females (33.5%) The overall positivity in direct microscopy ( KOH preparation) was 32% while positivity in culture was 51%.The most frequently isolated fungus was Fusarium (16) followed by A. flavus ( 07), A. fumigatus (06), Candida sp.(06) and Curvalaria (03) Conclusion: If medical therapy fails to control the infection, surgery should be considered to save the eye visual function before the progression of disease.

Study Of Clinical Outcomes In Patients With Severe Hepatic Injury: Experience At A Tertiary Care Centre.

Background: Management of liver trauma earlier used to be primarily surgical. With advancement in diagnostic modalities it has gradually shifted to non operative management. Methods: The present study was conducted on 40 patients with severe hepatic injuries (grade 3 onwards). All the patients were compared in terms of various methods adopted for their management and their clinical outcomes Results: Out of a total of 40 patients, maximum numbers of patients were in age group 18-24 years. 82.50 % patients had grade IV and rest had Grade V. 12 patients presented with shock on admission. Failure of NOM (non operative management) was seen in 25% of cases . The average requirement of blood transfusion in our study was 2.157 1.74 units. Average hospital stay in successful NOM cases was lower than in failed NOM. A total of 6 patients had to be operated upon in our study. Active bleed was seen on laparotomy in four patients with no evidence of any injury causing peritonitis. Conclusion: The success rates of non-operative management were significantly higher than the failures rates of non-operative management, without any significant incidence of complications and delayed laparotomies. Grade of liver injury or the amount of hemoperitoneum as detected on CT scan did not influence the outcome of non-operative management. Non-operative management is thus the gold standard in hemo-dynamically stable patients.

Pulmonary Manifestations in HIV Seropositive Patients and Their Correlation with CD4 Counts in a Tertiary Care Centre of North India.

The prolonged course of human immunodeficiency virus (HIV) infection is marked by a decrease in the number of circulating CD4+ T helper cells and persistent viral replication, resulting in immunologic decline and death from opportunistic infections. The study was conducted in HIV Seropositive Patients admitted in our hospital. Demographic profile of the patient was recorded along with history, examination, investigations and evaluated for pulmonary manifestations and correlated with the CD4 counts. Age of HIV positive cases ranged from 21 to 74 years, male: female ratio was 3:1. Commonest mode of transmission was heterosexual sex (77%) followed by IV drug abusers (13.3%). Commonest X- ray finding was Infiltrates (33.3%) followed by pleural effusion (8%) and miliary mottling (5.3%). Commonest pulmonary diagnosis was pulmonary tuberculosis in 22.6% cases, followed by pyogenic pneumonia in 14.67% and pneumocystis carinii pneumonia (PCP) in 5.3% cases. Extrapulmonary tuberculosis was present in 16% of the cases. Pulmonary tuberculosis and pyogenic pneumonia was present in over wide range of CD4 count but their incidence has increased as the CD4 count declined. The knowledge of the CD4 count level in HIV patients is extremely useful in making differential diagnosis and suggesting a diagnostic and therapeutic plan.

Gastric zygomycosis--an unusual cause of massive upper gastrointestinal bleed.

We report a 62-year-old man with cardiac failure and acute renal failure, who had massive hematemesis. Upper GI endoscopy showed a large gastric lesser curvature ulcer. Billroth II gastrectomy specimen showed fungal invasion. He received amphotericin B postoperatively, and recovered uneventfully.

Lactose maldigestion in different age groups of north Indians.

Lactase activity with age has been reported in a wide variety of population globally. However, most of these studies in human have ignored to assess age stratified lactose maldigestion. Therefore, the present study was planned to determine lactose maldigestion in different age groups of north Indians adults. Two hundred apparently healthy north Indians (age rage 10-80 years) were subjected to a 50g lactose hydrogen breath test by standard method using a Model 12 Microlyzer from Quintron, USA. The percentage of lactose maldigestion was calculated for different age groups with an interval of 10 years. The results of this study revealed that the frequency of lactose maldigestion did not differ significantly among the age groups. Thus, this study suggests that lactose maldigestion is not associated with age stratification among north Indians.

Plasmodium vivax malaria presenting with severe thrombocytopenia

Plasmodium falciparum and Plasmodium vivax malaria are endemic infections in India and are commonly associated with mild hematological abnormalities. Severe thrombocytopenia is common in isolated falciparum and mixed falciparum/vivax malaria, but is very rare in isolated P.vivax infection. We hereby report a case of severe thrombocytopenia (platelet count of 8x10(9)/L) in a case of vivax malaria. This is only the second case ever reported in the literature of such profound thrombocytopenia in a case of isolated P.vivax malaria
