Comparison of silver sulfadiazine 1%, mupirocin 2%, and fusidic acid 2% for topical antibacterial effect in methicillin-resistant staphylococci-infected,full-skin thickness rat burn wounds

Silver sulfadiazine 1%, mupirocin 2%, and fusidic acid 2% were compared to assess the antibacterial effect of a once-daily application on experimental rat 15% full-skin thickness burn wounds seeded 24 hours earlier with a 10 standard strain of methicillin-resistant staphylococci. The quantitative counts of seeded organism in burn eschar and subjacent muscle were determined at postburn day 7, beside the cultures of blood and lung biopsies. All tested topical agents were equally effective against methicillin-resistant in reducing local burn wound bacterial count and preventing systemic infection.     

Efficacy of isokinetic exercise on joint position sense and muscle strength in patellofemoral pain syndrome

OBJECTIVE: The objective of this study was to demonstrate the impairment of knee joint position sense in individuals with patellofemoral pain syndrome and investigate the effects of isokinetic exercise on knee joint position sense and muscle strength. DESIGN: A total of 24 male patients complaining of anterior knee pain caused by overexertion and 24 male healthy individuals without symptoms were included for this investigation. Isokinetic exercise protocol was carried out at angular velocities of 60 degrees/sec and 180 degrees/sec. These sessions were repeated three times per week and lasted for 6 wks. At the beginning and after 6 wks of knee passive joint position sense, quadriceps and hamstring muscle strength and pain assessments were performed. RESULTS: After the isokinetic exercise, flexion peak torque (P < 0.05), extension peak torque (P < 0.01), flexion total work (P < 0.001), extension total work (P < 0.001), passive reproduction of knee joint position sense for 40 degrees of flexion (P < 0.05) and 50 degrees of extension (P < 0.01), and pain score (P < 0.001) improved significantly in the patellofemoral pain syndrome group. CONCLUSION: Isokinetic exercises have positive effects on passive position sense of knee joints, increasing the muscular strength and work capacity. These findings show that using the present isokinetic exercise in rehabilitation protocols of patients with patellofemoral pain syndrome not only improves the knee joint stabilization but also the proprioceptive acuity.     

Ectopic opening of the common bile duct and duodenal stenosis: an overlooked association

Background  

Ectopic opening of the common bile duct into the duodenal bulb (EO-CBD-DB) is a rare disease that may be complicated by duodenal ulcer, deformity, stenosis and biliary stones. The aim of this study is to report clinical presentations, endoscopic diagnosis and treatment of this entity as well as to investigate its association with duodenal stenosis.     

Effect of prenatal exposure to an anti-inflammatory drug on neuron number in cornu ammonis and dentate gyrus of the rat hippocampus: a stereological study

Prenatal exposed to an anti-inflammatory drug is a major problem for the developing central nervous system. It is not well known the effect of prenatal exposed to a non-steroidal anti-inflammatory drug on the hippocampus. Total neuron number in one side of the cornu ammonis (CA) and gyrus dentatus (GD) of the hippocampal formation in control and drug-treated (diclofenac sodium, DS) groups of male rats was estimated using the optical fractionator technique. Each main group has also two subgroups that are 4 weeks old (4W-old) and 20 weeks old (20W-old). In CA, no significant difference between 4W-old DS-treated and their control was found, but a significant difference was observed between 20W-old DS-treated and their controls. A decreasing of neuron number was 12% for 20W-old DS-treated group. In GD, a decreasing of the granule cell number in 4W-old of DS-treated group was seen but an increasing of granule cell number was found in the 20W-old drug-treated rats in comparison to its control group, 7% and 9%, respectively. Although an increasing of neuron number in CA at the control group was seen with age, from 4th week to 20th week (10%), age-dependent substantial granule cell decline (17%) was observed in GD. No age effect on the total cell numbers of CA and GD of the drug-treated groups was seen in comparison to 4W-old week and 20W-old. A pronounced neuron loss observed in the drug-treated group may be attributed to the neurotoxicity of diclofenac sodium (DS) on the developing hippocampal formation. Age-dependent neuron increase in the CA of 20W-old and neuron decline in GD of 20W-old control groups may be a result of a dual effect of saline injection during the fetal life, since these animals were exposed to a stress of 15-day-period of saline injection, prenatal stress. The reason of no age effect on CA and GD cell number in the drug-treated groups may be attributed to the depletion of the progenitor cells due to neurotoxicity of DS in the fetal life of these animals.     

An unusual case of osteoid osteoma clinically mimicking sacroiliitis

Osteoid osteoma is one of the unusual causes of musculosceletal pain. A case of a 21-year-old man who had low back and hip pain radiating to the posterior thigh for 3 years is presented. Pain was worse at night but reduced with the use of nonsteroidal anti-inflammatory drugs. Straight leg raising test was negative. Patrick–Fabere and sacroiliac compression tests were positive on the right. Neurological examination was normal. Lumbar spinal and pelvic radiographs were normal except for sclerosis at the inferior half of the iliac bone adjacent to the right sacroiliac joint. Sedimentation rate, C-reactive protein, and whole blood counts were normal. Bone scan showed nonspecific increased uptake. Computed tomography revealed the presence of diffuse sclerosis at inferior half of the right iliac bone extending to medial border of sacroiliac joint with subcortical osteolytic region and centrally hyperdense sclerotic nidus inside.     

Simple provocative maneuvers in renal transplant scintigraphy for detecting urine leak

Urine leak in the early postoperative period following renal transplantation is a serious complication requiring early identification and aggressive intervention, which significantly reduces the morbidity and mortality. Renal transplant scintigraphy is a noninvasive method to evaluate the perfusion and function of a transplanted kidney and urinary drainage including urine leak. Here, we reported two cases in which the standard transplant renogram failed to demonstrate urine leak. The cases were referred for a diethylenetriaminepentaacetic acid renogram following the transplantation to evaluate the cause of symptoms or elevated serum creatinine level. In both the cases, urine leak was successfully detected following simple maneuvers such as diuretic administration or Foley catheter irrigation. Renal transplant scintigraphy is an effective and safe technique and the use of these simple maneuvers can enhance the diagnostic sensitivity of the transplant renogram in the detection of urine leak.     

Female urinary incontinence and the construction of nineteenth-century stigmatized womanhood

Before the 20th century, female urinary incontinence was a problematic disease because it presented a medical challenge (it was difficult to treat before the advent of surgical techniques) and prevented women from fulfilling their roles as spouses and caretakers. The latter was particularly troublesome during the 19th century when Western women (ie, white, middle/upper class, Protestant women) were expected to follow rigid, socially constructed gender roles, especially within the private microcosm of the family unit. Incontinent women of childbearing age had no place in the hierarchy of Euro-American society and were thus constructed as impure, polluted, and sexually undesirable. This stigmatization of the incontinent body not only marginalized the medical needs of the suffering woman but also characterized her as an unfeminine, contaminated, and repulsive object to be ostracized and excluded from the social rituals that defined selfhood.     

Soft tissue necrosis following using calcium phosphate cement in calcaneal bone cyst: case report

Calcium phosphate cements have received widespread attention for their possible role as bone-grafting material and bone fillers in skeletal defects. They were evaluated as a biomaterial in many aspects. No serious harmful effects such as foreign body reaction and tissue necrosis against to calcium phosphate cements have been reported yet. They were accepted as highly biocompatible materials. In this paper, we represent a patient who had soft tissue necrosis around lateral malleolar region, following using percutaneous calcium phosphate cement as a filler bone substitute in calcenous bone cyst. The possible mechanisms were discussed.
