Angioleiomyoma of the nasal cavity.

Angioleiomyoma is a rare benign tumor in the nasal cavity. There are very few reports in literature. A 34 year old male presented with left sided nasal obstruction and epistaxis. Clinical evaluation revealed a lesion replacing the anterior two-third of the Left inferior turbinate. An endoscopic excision under hypotensive anesthesia was performed. Histopathology confirmed a diagnosis of Angioleiomyoma. The cause and site of origin of angioleiomyomas when they arise from the inferior turbinate remains unclear. We review the literature available on nasal angioleiomyoma. When limited to the nasal cavity endoscopic excision is the treatment of choice.

Mycological profile of fungal sinusitis: An audit of specimens over a 7-year period in a tertiary care hospital in Tamil Nadu.

BACKGROUND: Fungi are being increasingly implicated in the etiopathology of rhinosinusitis. Fungal sinusitis is frequently seen in diabetic or immunocompromised patients, although it has also been reported in immunocompetent individuals. Invasive fungal sinusitis, unless diagnosed early and treated aggressively, has a high mortality rate. AIM: Our aim was to look at the mycological and clinical aspects of fungal sinusitis in a tertiary referral center in Tamil Nadu. DESIGN: This is a retrospective audit conducted on fungal culture positive sinus samples submitted to the Microbiology department from January 2000 to August 2007. Relevant clinical and histopathological details were analysed. RESULTS: A total of 211 culture-positive fungal sinusitis samples were analysed. Of these, 63% had allergic fungal sinusitis and 34% had invasive fungal sinusitis. Aspergillus flavus was the most common causative agent of allergic fungal sinusitis and Rhizopus arrhizus was the most common causative agent of acute invasive sinusitis. A significant proportion of these patients did not have any known predisposing factors. CONCLUSION: In our study, the etiology of fungal sinusitis was different than that of western countries. Allergic fungal sinusitis was the most common type of fungal sinusitis in our community. Aspergillus sp was the most common causative agent in both allergic and chronic invasive forms of the disease.

Radiofrequency ablation of liver tumors: experience with open and percutaneous approach.

BACKGROUND: Radiofrequency ablation (RFA), a thermal coagulation technique, has been used for ablation of primary and secondary liver tumors. METHODS: Over a 24-month period, 41 patients, including 20 with hepatocellular cancer (HCC), 14 with liver metastases from colorectal tumors and 7 with metastases from other tumors, underwent RFA in our institution. Ablation was done using intra-operative (n=27) or percutaneous ultrasonographic (n=14) guidance. A zone of ablation larger than the size of the lesion on CT scan indicated successful RFA. RESULTS: The mean size of lesions was 4.9 cm for HCC and 3.1 cm for metastases. Among 20 patients with HCC, 16 had complete tumor ablation and one had failure of localization. All patients with liver metastases had successful tumor ablation. There was no procedure-related death. Two patients had hemoperitoneum and one experienced skin burn. During a median follow up of 16 months, five patients with HCC and two with colorectal metastases died. One patient had tumor recurrence at the ablation site and two developed fresh solitary metastatic lesions; all three are disease-free after repeat ablation treatment. CONCLUSIONS: RFA is a safe and promising technique for the treatment of non-resectable HCC and liver metastases, in the short term.

Multilocular peritoneal inclusion cyst--a case report.

Multilocular Peritoneal Inclusion Cyst (MPIC) is a rare mesothelial lesion. It is most commonly found in women of reproductive age group involving the abdominal and pelvic peritoneum. Previously, this lesion was often confused with cystic lymphangioma, but now its mesothelial origin has been confirmed. We report a case of a 26-year old female who underwent Caesarean section during which cysts which were multiloculated, thin-walled and filled with serous fluid, were incidentally discovered. Its histopathologic examination established the diagnosis

Cardiovascular involvement in leptospirosis.

Cardiovascular involvement was studied in 50 patients with serologically proved leptospirosis. Twelve (24%) patients had dyspnoea and 18 (36%) had transient hypotension during the illness. None of them had cardiac enlargement, development of new murmur or pericardial rub. Various electrocardiographic abnormalities occurred in 70 percent of patients. Atrial fibrillation was the most common major arrhythmia (14%). Conduction system abnormalities were seen in 36 percent of patients. T-wave changes were observed in 30 percent of patients. Left ventricular function as assessed by echocardiography and Doppler examination was normal. Three (6%) patients died due to renal failure. In conclusion, even though ECG abnormalities were frequently seen in leptospirosis, there was no data to support associated left ventricular dysfunction. Dyspnoea and hypotension occurring in patients of leptospirosis must be due to a noncardiac mechanism.
