Clinical Characteristics and Management of Headache: A Real-Life Prospective, Observational Study From a Tertiary Care Center in Eastern India.

OBJECTIVE: To describe clinical profile and management pattern of headache in patients presenting to a tertiary care center.  Methods: In this observational study, demographics, radiological investigations, triggers, and treatment pattern in patients aged ≥ 14 years presenting with headache were recorded. Disability and severity of headache were assessed with Migraine Disability Assessment (MIDAS) score, Visual Analogue Scale (VAS), and Headache Impact Test (HIT-6) in case of migraineurs and VAS and HIT-6 for all other headache disorders. Patients were evaluated at baseline and after three and six months post-treatment. RESULTS: Out of 400 patients (60.25% females and 39.75% males), 277 (69.25%) had primary headache among whom 119 (42.96%) had migraine without aura. Stress, menstruation, fasting, and inadequate sleep were common triggers for migraine. Nausea, vomiting, photo-phonophobia and neck pain were the most common accompanying symptoms in patients with headache. Out of 106 (38.3%) patients with tension-type headache, 68.9% were episodic. In the migraine subset, 81% presented with moderate to severe disability at baseline, which changed to minimal to mild disability at three and six months post-treatment (p < 0.001). For abortive treatment, 130 (79.7%) patients were prescribed naproxen, domperidone, and sumatriptan. In 69 (42.3%) patients, valproic acid/divalproex was used for prophylaxis. Most common causes of secondary headaches (30.75%) were intracranial bleeds and cerebral venous sinus thrombosis. Most common abnormalities on computerized tomography were intracerebral hemorrhage, subarachnoid hemorrhage, sinusitis, and space-occupying lesions (SOLs). CONCLUSION: In our study, migraine was the most common etiology of headache. Headache was more common in females than males, and primary headache was more common than secondary headache. Sodium valproate was the commonly used prophylaxis in migraine.

Resurgence of Polymyxin B for MDR/XDR Gram-Negative Infections: An Overview of Current Evidence.

Polymyxin B has resurged in recent years as a last resort therapy for Gram-negative multidrug-resistant (MDR) and extremely drug resistant (XDR) infections. Understanding newer evidence on polymyxin B is necessary to guide clinical decision making. Here, we present a literature review of polymyxin B in Gram-negative infections with update on its pharmacology.

Polyuria, acidosis, and coma following massive ibuprofen ingestion.

Ibuprofen was the first over-the-counter nonsteroidal anti-inflammatory drug available in the United States. Despite being a common agent of ingestion, significant toxicity in overdose is rare. We report a case of a massive ibuprofen ingestion who developed polyuria, acidosis, and coma but survived, despite having a serum ibuprofen concentration greater than previous fatal cases. A 19-year-old man ingested 90 g (1,200 mg/kg) ibuprofen. He was initially awake and alert, but his level of consciousness deteriorated over several hours. Seven hours following the ingestion, he was intubated and mechanically ventilated secondary to loss of airway reflexes. He developed a lactic acidosis and polyuria, which lasted for nearly 24 h. His serum creatinine peaked at 1.12 mg/dL. An ibuprofen level drawn 7 h postingestion was 739.2 mg/L (therapeutic 5-49 mg/L). We describe a case of a massive ibuprofen overdose characterized by metabolic acidosis, coma, and a state of high urine output who survived with aggressive supportive care. This case is unique in several ways. First, ibuprofen levels this high have only rarely been described. Second, polyuria is very poorly described following ibuprofen ingestions.

Pauci-immune and immune glomerular lesions in kidney transplants for systemic lupus erythematosus.

BACKGROUND AND OBJECTIVES: Glomerular lesions in allografts in recipients with end-stage nephritis resulting from systemic lupus erythematosus (SLE) were examined to determine the spectrum of glomerular pathology in recurrent glomerulonephritis (GN). DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: A total of 156 biopsy samples, from 49 serial allografts in 43 recipients with end-stage lupus nephritis, were examined by light microscopy, and by immunofluorescence and electron microscopy in selected cases. These were compared with control allografts (n = 35). RESULTS: Glomerular lesions best explained by recurrent lupus nephritis were observed in 19 of 49 allografts (38.8%) in lupus recipients. Three categories of glomerulopathies were identified: 1) immune complex glomerulopathies, including mesangial GN (28%) and membranous GN (4%); 2) atypical glomerulopathies, including acute proliferative GN (32%) and focal segmental glomerulosclerosis (12%), with scant immune deposits in glomerular capillaries, frequent endothelial tubuloreticular inclusions, and thrombotic microangiopathy; and 3) transplant-associated glomerulopathies (24%). CONCLUSIONS: Allografts from recipients with SLE had typical immune complex-mediated GN and atypical pauci-immune, proliferative GN and segmental glomerular sclerosis. Atypical glomerulopathies like these suggest a role for nonimmune complex-mediated glomerular injury in recurrent lupus GN.

Religious beliefs and quality of life in an American inner-city haemodialysis population.

BACKGROUND: The ability to adapt to the long-term aspects of chronic haemodialysis is multifactorial and poorly understood. Given the many comorbidities of a patient on haemodialysis, religious beliefs may be an important factor in the patient's ability to cope. METHODS: End-stage renal disease patients in an inner-city American in-center haemodialysis unit were given two surveys to quantify their quality of life (KDQOL) and beliefs (Royal Free Score). The population studied included 97% African Americans. The demographics were collected and recorded. The relationship between religious/spiritual beliefs, demographic variables, and how quality of life (QOL) is viewed was analysed. RESULTS: The vast majority of patients considered themselves religious, spiritual or both. KDQOL scores did not correlate with belief in a higher power, but the non-religious group demonstrated a significantly lower blood urea nitrogen (BUN) and creatinine as compared with the religious group. There was a negative correlation with age and physical function as reported by KDQOL and physical health composite. CONCLUSION: As physical function declines, religious and spiritual beliefs are stronger in the haemodialysis population studied. Given the overwhelming prevalence of religious and spiritual beliefs in this population, further study is needed as acknowledging and incorporating these beliefs into patient treatment plans may be warranted.
