OBJECTIVEThe treatment of subtrochanteric fractures is challenging and treatment modalities and implants are constantly evolving. This study attempts to revisit and compare extramedullary vs. intramedullary devices in relatively young population.
METHODSThirty patients with subtrochanteric fractures were enrolled and treated with extramedullary or intramedullary devices and follow-up continued one year for clinico-radiological assessment.
RESULTSThe mean age of patients was 37.53 years. Most were males between 21-40 years. The dominant mode of injury was traffic accidents (66%). Fractures were classified according to Russell-Taylor classification. Forty percent were Russell-Taylor type IA, 37% type IB and 23% type IIA. Average time to surgery was 3.6 days from the time of admission to hospital. Mean duration of surgery was 45 minutes for intramedullary device (group A) and 105 minutes for extramedullary device (group B). Average blood loss was 100 ml in group A and 200 ml in group B. Mean duration of radiation exposure was 130 seconds and 140 seconds for groups A and B, while average duration of hospital stay was 12 days and 16 days respectively. Excellent results were seen in 47% of cases in group A and 33% of cases in group B.
CONCLUSIONIntramedullary device is a reliable implant for subtrochanteric fractures. It has high rates of union with minimal soft-tissue damage. Intramedullary fixation has biological and biomechanical advantages, but surgery is technically demanding. Gradual learning and patience is needed to make this method truly rewarding.

With rapid advancement in surgical techniques and improvement in implant materials, rate of internal fixation for pubic symphyseal disruption in rotationally and vertically unstable pelvic ring injuries has increased. Among various modes of implant failure, screw/plate breakage and loosening are common complications following unstable fixation. Migration of loose screws into the urinary bladder has been reported as an extremely uncommon complication of pubic symphyseal plating. Here we present a case report of a 52-year-old female who presented with asymptomatic passage of screws in her urine following migration into the bladder, 2 years after symphyseal plating for pubic diastasis in an anteroposterior compression pelvic ring injury.

Recent studies have identified sprue-like illness associated with the use of the antihypertensive agent olmesartan medoxomil. However, whether this condition is specific to the use of olmesartan or is associated with the use of drugs belonging to the class of “sartans” remains to be clarified. A 45-year-old woman with chronic kidney disease along with hypothyroidism and hypertension presented with chronic diarrhea and significant weight loss. Endoscopy of the upper gastrointestinal tract showed scalloping and grooving of the duodenum, and histopathological examination showed subtotal villous atrophy. She was on telmisartan for hypertension, which was discontinued. Subsequently, diarrhea ameliorated dramatically, and she regained weight. To our knowledge, this is the first study to report telmisartan-associated sprue-like enteropathy. Further, we have reviewed the cases of patients with sprue-like enteropathy caused by valsartan, irbesartan, and eprosartan.

Intranasal drug administration is receiving increased attention as a delivery method for bypassing the blood-brain barrier and rapidly targeting therapeutics to the CNS. However, rapid mucociliary clearance in the nasal cavity is a major hurdle. The purpose of this study was to evaluate the effect of mucoadhesive polymers in enhancing the delivery of nimodipine microemulsion to the brain via the intranasal route. The optimized mucoadhesive microemulsion was characterized, and the in vitro drug release and in vivo nasal absorption of drug from the new formulation were evaluated in rats. The optimized formulation consisted of Capmul MCM as oil, Labrasol as surfactant, and Transcutol P as co-surfactant, with a particle size of 250 nm and zeta potential value of -15 mV. In vitro and ex vivo permeation studies showed an initial burst of drug release at 30 min and sustained release up to 6 h, attributable to the presence of free drug entrapped in the mucoadhesive layer. In vivo pharmacokinetic studies in rats showed that the use of the mucoadhesive microemulsion enhanced brain and plasma concentrations of nimodipine. These results suggest that incorporation of a mucoadhesive agent in a microemulsion intranasal delivery system can increase the retention time of the formulation and enhance brain delivery of drugs.
