Pneumocephalus is defined as air in the cranial cavity. Pneumocephalus can result from inadvertent dural puncture during lumbar epidural anesthesia or epidural steroid injection. Presently described is case of 41-year-old woman who had undergone lumbar disc hernia operation but due to ongoing complaints, was diagnosed as having failed back surgery syndrome. Percutaneous epidural neuroplasty was performed. In the operating room, under sterile conditions and under sedoanalgesia, Racz catheter was inserted in caudal area and guided to epidural area with scope. In accordance with Madrid Declaration, 20 ug/mL concentration and 5 mL volume oxygen-ozone mixture was injected. After waiting 5 minutes, 0.25% bupivacaine + 80 mg triamcinolone + 1500 units hyaluronidase was administered through the catheter. After epidural neuroplasty procedure, when patient was taken to gurney, she complained of severe headache and nausea. Computed tomography scans of head were done immediately, and consistent with pneumocephalus, air was observed in right lateral ventricle frontal horn, interhemispheric fissure, and superior cerebellar cistern. Patient was placed in Trendelenburg position and intravenous fluid was replaced. Analgesics and bed rest were recommended as treatment. Patient was discharged from hospital on the second day. Within a week, headache pain and other complaints had resolved. In this article, the case of a failed back surgery patient who was postoperatively treated with medical ozone and experienced complication of pneumocephalus is discussed in context of literature data.

OBJECTIVE:

To compare the effects of bio-oxidative ozone application with occlusal splints in temporomandibular disorder (TMD) patients with pain.

 

METHODS:

Forty participants were selected after the diagnosis of TMD and randomly divided into two groups: ozone group (OG, n = 20) and occlusal splint group (OCSG, n = 20). Ozone was applied to patients three times per week, for a total of six sessions. Patients in the OCSG were instructed to use occlusal splints every night over a period of four weeks.

 

RESULTS:

Mandibular movements showed significant differences for the time factor in OG and OCSG. Pressure pain thresholds of the temporal and masseter muscles at follow-up were significantly higher in the OCSG group. Both treatments statistically decreased the visual analog scale (VAS) scores. However, no statistically significant difference was observed between groups after the application of treatments.

 

DISCUSSION:

Occlusal splint treatment is still the gold treatment modality for objective pain relief in patients with TMD pain.

 

KEYWORDS:

Ozone; occlusal splints; orofacial pain; temporomandibular joint disorders

Dry eye, an age-related condition, is a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance and tear film instability. Environmental factors are also often implicated in dry eye including exposure to pollutants, ultraviolet (UV) radiation and ozone as well as the chronic use of preserved eyedrops such as in the treatment of glaucoma. These factors increase oxidative stress and ocular surface inflammation. Here, we reviewed the cellular, animal and clinical studies that point to the role of oxidative stress in dry eye disease. The biomarkers used to indicate oxidative damage in ocular surface tissues include 8-hydroxy-2 deoxyguanosine (8-OHdG), 4-hydroxynonenal (HNE) and malondialdehyde (MDD). Antioxidative defences in the ocular surface occur in the form of tear proteins such as lactoferrin and S100A proteins, and enzymes such as superoxide dismutase (SOD), peroxidase, catalase and mitochondrial oxidative enzymes. An imbalance between the level of reactive oxygen species (ROS) and the action of protective enzymes will lead to oxidative damage, and possibly inflammation. A small number of interventional studies suggest that oxidative stress may be directly targeted in topical therapy of dry eye treatment. For example, in vitro studies suggest that L-carnitine and pterostilbene, a blueberry component may reduce oxidative stress, and in animal studies, alpha-lipoic acid (ALP) and selenoprotein P may be helpful. Examples of treatments used in clinical trials include vitamin B12 eyedrops and iodide iontophoresis. With recent emphasis on ageing medicine and preventive holistic health, as well as the role of environmental science, research on oxidative stress in the ocular surface is likely to have increasing impact in the coming years.
