RESUMO
RATIONALE: Antibacterials are largely prescribed to the intensive care unit (ICU) patients due to high prevalence of infections. However, appropriate use of antibacterials is imperative; since the misuse of antibacterials increases antibacterial resistance and ultimately, it has negative impact on health care and economic system. Hence, continuous antibacterials prescription assessments are very important to judge and improve prescription patterns. The present work was carried out at public and private hospitals to assess the differences in antibacterial prescribing pattern. METHODS: The present study was conducted at three public and two private hospitals over the period of 14 months. Demographic and drug use details were captured daily from patients admitted to medical ICUs to assess the World Health Organization indicators. RESULTS: A total of 700 patients were enrolled across the five centers (140 per center), among them 424 were male and 276 were female. Average number of drugs and antibacterials prescribed at public hospitals are significantly higher than the private hospital. However, percentage of antibacterial agents prescribed at public hospitals was significantly lower than the private hospitals (P = 0.0381). Private hospitals had significantly lower percentage of antibacterial agents prescribed by generic name (P < 0.0001). Differences in change of antibacterial agents required were not statistically significantly different (P = 0.1888); however, significant difference was observed in percentage of patients who received antibacterial treatment as per sensitivity pattern (P = 0.0385) between public and private hospitals. Significantly higher mortality was observed in public hospitals compared to private hospitals (<0.0001). CONCLUSIONS: More generic prescriptions and more number of prescriptions as per the sensitivity pattern are required at each public and private hospital.
RESUMO
The aim of this study is to describe the clinical presentation of central skull base osteomyelitis and to discuss the classical imaging findings and various diagnostic and therapeutic challenges faced in the management of this condition. This is a retrospective analysis of inpatient case records, carried out in a multidisciplinary tertiary care hospital. The study subjects included five elderly diabetic patients presenting to the ENT surgeon or neurologist with headache followed by multiple cranial nerve paralysis with no temporal bone involvement in four patients and a past history of otitis externa in one patient. These patients were diagnosed to have an infective pathology of the central skull base detected by imaging and confirmed by biopsy in three. All were treated successfully with antibiotics administered for an average period of 6 weeks. Three patients followed up over 4 years and showed no relapses. One succumbed to other medical co morbidities after 8 months and one diagnosed a month prior is still under follow up. A symptom complex of headache and cranial neuropathies usually raises the suspicion of malignancy. Central skull base osteomyelitis, a relatively uncommon pathology, must also be considered as a possible differential diagnosis despite absence of a definite septic focus. Imaging studies showing bony destruction and adjacent soft tissue involvement should raise the suspicion of this clinical entity. Malignancy needs to be ruled out by biopsy. Early diagnosis and prompt initiation of antibiotics administered for an adequate duration is of paramount importance in successfully treating these patients. A multidisciplinary approach is needed for a successful outcome.
