Incidence, Diagnosis and Treatment of Otorhinolaryngologicl, Head and Neck Tuberculosis: A Prospective Clinical Study

Abstract Introduction Tuberculosis is a disease of diversified presentation. It affects almost all organs in the body, and otorhinolaryngological, head and neck involvement is not an exception. Objective To increase awareness about the different clinical presentations of otorhinolaryngological, head and neck tuberculosis, the techniques employed to diagnose it, and to assess the response to the treatment. Methods We conducted a prospective study of 114 patients who presented primarily with otorhinolaryngological, head and neck tuberculosis. Routine blood investigations, chest radiographs, the tuberculin test, and sputum examination for the presence of acid-fast bacilli were performed in all cases. Site-specific investigations were performed in relevant cases only. The patients were treated according to the antitubercular treatment (ATT) regimen recommended by the Indian Ministry of Health and Family Welfare's National Tuberculosis Elimination Program (NTEP), and they were followed up clinically two and six months after starting the ATT. Results Tubercular cervical lymphadenopathy was the most common clinical presentation (85.96%), followed by deep neck abscess (5.27%). Fine-needle aspiration cytology proved to be a reliable tool for the diagnosis of tubercular lymphadenopathy. Improvement at the end of 2 and 6 months of the ATT was observed in 90.35% and 96.50% of the cases respectively. Conclusion The diagnosis of otorhinolaryngological, head and neck tuberculosis requires a high index of clinical suspicion, and the ATT proved to be very effective in reducing the severity of the disease.

A study on presentation and behavior of colo-rectal carcinoma in young Indian patients.

Background: Colorectal cancer is rare in younger age group. Most cases occur in the second decade of life and are clinically aggressive. The prognosis of these patients is generally poor. This is a retrospective study in which data of Indian patients was compared to standard literature. Methods: Data on 32 young patients with colorectal cancer between ages of 10-25 years treated between January 2000 and December 2006 was reviewed. Clinical presentation, natural history and response to therapy were evaluated. Results: Studied cases comprised 9.9% of the total number of colorectal cancer patients. The median age of presentation was 21.5 years. Four-fifths of the cases presented in late stage. Nodal involvement was seen in 38% cases and metastatic disease in 12% cases. The rectum was the most commonly involved site. A majority of the patients presented with pain (81%), altered bowel habits (72%) and bleeding per rectum (78%). Surgery was done in 16 cases; radiotherapy in 16 patients; while chemotherapy was used in 19 cases. Responses at completion of treatment were seen in 28% cases; while 1 year post treatment only 12% cases were alive and only 6% at 2 years. Conclusions: Colorectal cancer in younger age is rare and a high level of suspicion is necessary to diagnose it at an early and curable stage. Rectal bleeding therefore should not be ignored but evaluated further with at least a digital rectal examination and a sigmoidoscopy. Failure to do so results in late presentation with consequent dismal survival rates.

Primitive neuroectodermal tumor of prostate.

Primitive neuroectodermal tumors (PNETs) are malignant proliferations of small, undifferentiated neuroectodermal cells occurring mainly in children and share the same reciprocal translocation between chromosomes 11 and 22 and the same patterns of biochemical and oncogene expression as osseus and extraosseus Ewing's sarcoma. Some PNETs occur in the brain, while others (the peripheral PNETs) occur in sites outside the brain, such as in the extremities, pelvis and the chest wall. They mostly originate in the chest, pelvis and retroperitoneum; in rare cases, occurrence in the head and neck area has also been seen. We present a rare case of primitive neuroectodermal tumor arising in the prostate gland in a 25-year-old male. To the best of our knowledge, this is the first documentation of a primary peripheral primitive neuroectodermal tumor in the prostate gland of any patient from India and rarely reported in English literature.

In vitro evaluation of antibacterial activity of an herbal dentifrice against Streptococcus mutans and Lactobacillus acidophilus.

Antibacterial activity of a herbal dentifrice Arodent against Streptococcus mutans and Lactobacillus acidophilus was evaluated using Colgate as standard. Both bacterial strains were isolated from the oral cavity on selective media and identified by standard methods. The antibacterial activity was assayed by cup-well method. The bacterial lawn of facultative anaerobe S. mutans was established between two layers of agar under microaerophilic conditions. Five and a half millimeters and 10 mm zones of inhibition were produced by Arodent against S. mutans and L. acidophilus , respectively, under microaerophilic conditions. On the other hand, the standard dentifrice Colgate produced 5.83 mm and 10.17 mm zones of inhibition against S. mutans and L. acidophilus , respectively, under microaerophilic condition. The results suggest that Arodent is an effective antibacterial herbal dentifrice.

Fungistatic activity of Semecarpus anacardium Linn. f nut extract.

Alcoholic extract of dry nuts of S. anacardium showed dose dependent antifungal activity in vitro against Aspergillus fumigatus and Candida albicans. At 400 mg/ml concentration, growth of both the fungi was inhibited and considerable reduction in size of cells and hyphae was observed. Sporulation also decreased.
