Impact of oral palonosetron in improving quality of life as compared to other oral 5-HT3 antagonists in delayed chemotherapy induced nausea and vomiting in patients of head and neck cancer

Background: Chemotherapy induced nausea and vomiting (CINV) remains one of the most common and debilitating complications of highly emetogenic chemotherapy (HEC). This study was undertaken to evaluate palanosetron against other 5-HT3 receptor antagonists in preventing delayed CINV with the aim of achieving complete response (CR) and improving quality of life (QoL).Methods: This was a prospective, observational study conducted on 75 histopathologically proven patients of squamous cell carcinoma of Head and Neck (H&N), who came to the Department of Radiation Oncology, Gandhi Medical College and Hamidia Hospital, Bhopal from January to December 2015. Standard protocol based chemotherapy containing highly emetogenic cisplatin based chemotherapy was administered to all the patients. For prevention of delayed chemotherapy induced nausea and vomiting all patients were prescribed oral 5-HT3 antagonists. Oral Ondansetron 4mg TDS was given to cohort 1, oral Granisetron 1 mg BD to cohort2 and oral Palanosetron 0.5mg OD was given to cohort 3. They were graded as complete response when they did not have complains of nausea and vomiting.Results: In Ondansetron, Granisetron and in Palanosetron cohort 29%, 53% and 98% patients had complete response.Conclusions: Palanosetron appears superior. Our study was conducted on handfull of patients and compared palanosetron against only two 5-HT3 receptor antagonists, so a larger study is suggested to establish the efficacy and better response of palanosetron.

Suppurative dacroadenitis causing ocular sicca syndrome in classic Wegener’s granulomatosis.

Wegener’s granulomatosis (WG) is a multisystem vasculitic disorder which can commonly afflict various components of the eye. Here we describe some unusual ocular manifestations of the disease in one patient. A young male with history of upper respiratory tract symptoms including epistaxis, nasal stuffiness and maxillary sinus pain presented with bilateral lacrimal gland abscess and ptosis. Lacrimal gland biopsy revealed granulomatous vasculitis. Lung cavities, positive cytoplasmic-antineutrophil cytoplasmic antibodies and high titers of serine proteinase-3 antibodies confirmed the diagnosis of WG. The patient developed dry eyes after a month of first presentation. There was no dryness of mouth, suggesting the absence of salivary gland involvement, and antinuclear antibodies as well as antibodies against Ro and La antigens classical of primary Sjogren’s syndrome were absent. Granulomatous vasculitis of lacrimal gland leading to abscess formation and dryness of eyes has not been described in WG and reflects the aggressive nature of inflammatory process in this disease.

Childhood polyarteritis nodosa: a clinical diagnosis.

A six-year old boy presented with dry gangrene of toes and fingers with hypertension with no other systemic abnormalities. He had persistently high inflammatory parameters, was diagnosed as childhood classic polyarteritis nodosa and showed improvement with immunosuppressants along with antihypertensives. Toe gangrene required amputation in view of superadded infection.
