Fracture of isolated spinous processes at multiple levels is a rare injury. Herein, we present a 45-year-old male with cervical pain and swelling following a road traffic accident. Computerized tomography and magnetic resonance imaging revealed fractures of spinous process from C7 to D6 vertebra. The patient was managed with rest, analgesics and immobilization. At the 1-year follow-up, the patient is doing well without any neurological problem. 相似文献

The recurrence of pressure ulcers (PrUs) and dehiscence of reconstructive flap have always been a problem. The present study aimed to evaluate the results of reconstructive flap surgeries in patients with spinal cord injury (SCI) having PrUs, using classic and modified flaps with improvisations to decrease wound dehiscence, flap necrosis and tension in flap. This is a prospective clinical study. The setting was a tertiary care centre in northern India. Thirty‐five patients with SCI having 37 stage III and IV PrUs. PrUs were treated using classic and modified flaps with improvisations. The outcome was evaluated using criteria of wound dehiscence, flap necrosis and recurrence. The results of flap surgery were excellent in 32 (86·48%) patients, good in 4 (10·81%) patients and poor in 1 (2·7%) patient. Partial flap necrosis (2·7%), low incidence of PrU recurrence rate at flap site (5·4%) and overall PrU recurrence (11·4%) were the complications observed. Improvisation of classic and modified techniques of flap surgeries along with reinforcement of general care principles of paraplegia can be effective in minimising complications often associated with PrU reconstructive surgery thus improving the ultimate outcome. 相似文献

In recent past, direct-acting anti-viral drugs (DAAs) have become the standard of care for the treatment of hepatitis C virus (HCV) infection. However, the experience with the use of these drugs in Indian renal transplant recipients is limited. We retrospectively reviewed our experience with DAA-based treatment for HCV infection in such patients. Between April 2015 and December 2016, six adults (median age 41 [range 34–52] years, male 5; GT1 2, GT3 3, and GT4 1; including three with prior failed interferon-based treatment) had received genotype-guided, DAA-based anti-HCV treatment 1 to 158 (median 15) months after renal transplantation. Of them, four completed the planned 24-week treatment without any significant adverse event. One of them had increase in serum creatinine after 16 weeks of treatment with sofosbuvir and daclatasvir, with acute interstitial nephritis on kidney biopsy; his renal function improved on stopping the drugs. The other patient had preexisting mild renal dysfunction, which worsened after 8 weeks of sofosbuvir-ledipasvir treatment; this did not reverse on stopping treatment. All the six patients achieved undetectable HCV RNA after 4 weeks of treatment and also achieved sustained virologic response, i.e. lack of detectable HCV RNA in serum 12 weeks after stopping treatment. Overall, DAA-based treatment was effective in treating HCV infection in our renal transplant recipients; however, caution and monitoring of renal function during such treatment is advisable in patients who have additional factors that predispose to renal injury. 相似文献

Chronically bedridden patients are predisposed to various urological complications such as urinary infections, incomplete urinary bladder emptying after voiding and stone formation in the urinary tract, more so in the absence of good nursing care. Multiple giant bladder stones giving rise to ‘cannon ball’ appearance have rarely been reported. We present the case of an 85‐year‐old frail gentleman who was bedridden for the last 25 years and presented with haematuria. On evaluation he was found to have multiple large bladder stones and bladder diverticuli with enlarged prostate gland. This case highlights a relatively rare urological complication of prolonged recumbency, and emphasizes the importance of proper nursing care, early detection, management and prevention of such complications. 相似文献

We describe a rare case of pulmonary valve endocarditis associated with a double‐chambered right ventricle in an adolescent male highlighting the two‐dimensional and three‐dimensional transthoracic echocardiographic findings. He was managed with aggressive antibiotic therapy followed by surgery. The echocardiographic findings were confirmed during surgery. 相似文献
