Effect of photobiomodulation therapy on headache, and fatigue in patients with chronic rhinosinusitis: a randomized controlled study.

Chronic rhinosinusitis (CRS) is a debilitating disease that resists medical treatment. Photobiomodulation therapy is one of the promising treatment modalities for CRS. The purpose is to investigate the effect of photobiomodulation therapy on headache, fatigue, sinus opacification, and ostiomeatal complex obstruction in patients with CRS. Thirty-one patients with CRS were randomly divided into photobiomodulation therapy and control groups. The photobiomodulation therapy group received photobiomodulation therapy (2.5 J, frequency 9.12 Hz, and 904 nm for 10 min for 12 sessions) on eight rhinosinusitis sites, and the control group received a sham laser. Headache, fatigue, and sinus opacification outcomes were measured before and after treatment. There was a significant improvement in headache, fatigue, and sinus opacification in the photobiomodulation therapy group in comparison with the control group (p < 0.05). Photobiomodulation therapy is an effective physical therapy treatment modality for the management of CRS.Clinical trial registry: NCT05861817.

Utility of whole brain radiation therapy for leptomeningeal carcinomatosis.

BACKGROUND: Although whole brain radiation therapy (WBRT) is commonly used as first-line treatment for leptomeningeal carcinomatosis, the prognosis is uncertain despite treatment. Moreover, the benefit of WBRT for leptomeningeal carcinomatosis has not been adequately evaluated. Therefore, this study aimed to clarify the utility of WBRT for leptomeningeal carcinomatosis. METHODS: Consecutive patients who received WBRT for leptomeningeal carcinomatosis or brain metastasis from solid tumors between January 2008 and July 2017 were retrospectively evaluated. The overall survival, symptom relief, and adverse events were compared between patients with leptomeningeal carcinomatosis and those with brain metastasis after WBRT. RESULTS: Of the 277 treated patients, 204 patients (22 with leptomeningeal carcinomatosis and 182 with brain metastasis) were included in the study. The median overall survival was 440 days (95% confidence interval [CI] 0-931 days) for patients with leptomeningeal carcinomatosis and 322 days (95% CI 196-448 days) for those with brain metastasis (p = 0.972 on the log-rank test). On evaluating the overall survival of patients with leptomeningeal carcinomatosis, the prognostic factors of performance status 0-1, no extracranial metastasis, and no symptoms at the time of WBRT showed a significant survival advantage on univariate analysis. Among patients with leptomeningeal carcinomatosis, those with headache and nausea often showed improvement while those with depressed levels of consciousness and seizures did not. On comparing all-grade adverse events, vomiting and seizures were more frequent in patients with leptomeningeal carcinomatosis than in those with brain metastasis. CONCLUSIONS: WBRT was generally well tolerated and effective for treating patients with leptomeningeal carcinomatosis.

Gamma Knife Radiosurgery for Short Unilateral Neuralgiform Headache Attacks with Conjunctival Injection and Tearing (SUNCT) Syndrome: Targeting the Trigeminal Nerve and the Sphenopalatine Ganglion. Case Report and Literature Review.

BACKGROUND: Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a primary headache syndrome with an unclear pathogenesis, and only in very few cases, SUNCT is secondary to known lesions (secondary SUNCT). Several pharmacological as well as interventional and invasive treatments have been used to treat SUNT cases, with no definitive results. We describe a patient with idiopathic SUNCT syndrome, successfully treated with gamma knife radiosurgery and we report a review of the cases of the literature treated with radiosurgery. CASE REPORT: A 63-year-old woman complained of episodes of intense and regular paroxysmal facial pain in the territory of the maxillary branch of the trigeminal nerve accompanied by inflammation of conjunctiva and involuntary lacrimation from 2006. During the following years, she received several treatments: combination of drugs, acupuncture, and endonasal infiltration of the sphenopalatine ganglion. The frequency of the painful attacks increased progressively and it was impossible for her to have a normal active life. Combined gamma knife radiosurgery treatment, targeting the trigeminal nerve (80 Gy maximum dose) and the sphenopalatine ganglion (80 Gy maximum dose) was performed in April 2016 (visual analog score before treatment = 6). Pain gradually reduced in the following months, as well as frequency and severity of the attacks. No sensory deficit developed. The follow-up length of our patient is 37 months: she is nearly pain free (visual analog score = 2) and has resumed a normal life. CONCLUSIONS: Patients with idiopathic SUNCT have few therapeutic options. Our case demonstrates that gamma knife radiosurgery is a feasible and effective noninvasive option to treat patients with medically refractory idiopathic SUNCT.

Significant Hemorrhage Rate Reduction after Gamma Knife Radiosurgery in Symptomatic Cavernous Malformations: Long-Term Outcome in 95 Case Series and Literature Review.

BACKGROUND: The natural history of cavernous malformations (CMs) has remained unclear. This lack of knowledge has made treatment decisions difficult. Indeed, the use of stereotactic radiosurgery is nowadays controversial. The purpose of this paper is to throw light on the effectiveness of Gamma Knife radiosurgery (GKRS) therapy. METHODS: The authors reviewed data collected from a prospectively maintained database. A total of 95 patients (57 female and 38 male) underwent GKRS for high-surgical-risk CMs. A total of 76 cavernomas were deeply located (64 lesions in the brainstem and 12 lesions in the thalamus). All of them were located in eloquent regions. The median malformation volume was 1,570 mm3. The median tumor margin dose was 11.87 Gy, and the mean tumor maximum dose was 19.56 Gy. RESULTS: Ninety-five cavernous CMs were managed from 1994 to 2014. All patients had experienced at least 1 symptomatic bleeding incident before treatment (only 1 hemorrhage event in 81%). The median length of follow-up review was 78 months. The pretreatment annual hemorrhage rate was 3.06% compared with 1.4% during the first 3-year latency interval, and 0.16% thereafter (p = 0.004). Four patients developed new location-dependent neurological deficits, and 3 patients had edema-related headache after radiosurgery. All of them presented full recovery. CONCLUSIONS: The best dosage range for preventing bleeding was identified as between 11 and 12 Gy in our series. Although the efficacy of radiosurgery in CMs remains impossible to quantify, a very significant reduction in the bleeding rate occurs after a 3-year latency interval. No permanent neurological morbidity is reported in our series. These results defend the safety of GKRS in surgical high-risk CM from the first bleeding event.

Radiosurgery with a Rotating Gamma System: A Very Effective Treatment for Symptomatic Cerebral Cavernomas.

AIM: To evaluate the value of radiosurgery with a rotating gamma-system (RGS) for cerebral cavernomas. PATIENTS AND METHODS: Seventy-nine patients with symptomatic cerebral cavernomas underwent RGS radiosurgery at the Bach Mai Hospital, Hanoi, Vietnam. Median dose (single fraction) was 20 Gy (range=14-26 Gy). Endpoints included effect on headache, seizures and tumor size. RESULTS: Of 60 patients with headache, 17% had complete response, 82% partial response and 2% stable disease (best response). Of 39 patients with seizures, 31% had complete response, 64% partial response and 5% stable disease. Four patients developed recurrent seizures after 1 year. Regarding the size of cavernoma at 15 months, complete response was observed in 6%, partial response in 75%, stable disease in 15%, progression in 1% and pseudo-progression in 3% of patients. Bleeding within 2 years after RGS radiosurgery occurred in only five patients (6%). RGS dose had no significant impact on outcomes. CONCLUSION: RGS radiosurgery provided very high rates of symptom relief in patients with cerebral cavernomas.

Management of myofascial pain: low-level laser therapy versus occlusal splints.

The present study was designed to compare the effects of low-level laser with occlusal splints in patients with signs and symptoms of myofascial pain (MP) dysfunction syndrome. A total of 40 (34 women and 6 men, with a mean age of 32.84 [SD, 10.70] years) were selected after the diagnosis of MP according to the Research Diagnostic Criteria for Temporomandibular Disorder. The patients were randomly divided into 2 groups: study group (n = 20) and control group (n = 20). Low-level laser was applied to patients in the study group 2 times per week, for a total of 10 sessions. Patients in the control group were instructed to wear occlusal splints 24 h/d for 3 months. The functional examination was based on Research Diagnostic Criteria for Temporomandibular Disorder and pressure pain threshold values were obtained with the aid of an algometer in both groups. Patients' self-report of pain was evaluated with visual analog scale. Comparisons were made within and between the groups before and after treatment. Vertical movements showed statistically significant improvements after the treatments in both groups (P < 0.01), but when the groups were compared with each other, there were no significant difference between the groups. In both groups, tenderness to palpation of the muscles decreased significantly. Pressure pain threshold evaluations and visual analog scale scores revealed similar results, too. This particular type of low-level laser therapy (820 nm, 3 J/cm2, 300-mW output power) is as effective as occlusal splint in pain release and mandibular movement improvement in MP.

Estimulación eléctrica invasiva de C2-C3 en el tratamiento del dolor cefálico y facial: Neuralgia occipital. Migraña transformada. Cefalea en racimos. Algias faciales / C2-C3 Invasive electrical stimulation for the treatment of cephalic and facial pain: occipital neuralgia. Transformed migraine. Cluster headache. Facial algias

Introducción: La estimulación eléctrica extraespinal periférica cervico-occipital, llevada a cabo con un sistema implantado, es una técnica quirúrgica poco cruenta que puede proporcionar buenos resultados en pacientes con dolor neuropático refractario localizado en región cefálica y facial. Presentamos treinta y cuatro pacientes con dolor cervico-facial de larga evolución, persitente, severo, no controlado, de diferentes etiologías, en los que se habían agotado otras posibilidades terapéuticas, tratados en la Unidad del Dolor del Hospital Clínico, con estimulación eléctrica y electrodo cervico-occipital uni o bilateral. Material y método: Se trata de 34 pacientes tratados en el período de Junio 2002 a Febrero de 2008. Catorce de estos pacientes cumplían criterios diagnósticos de Migraña Transformada; otros dos casos se trataba de cefalea en racimos y en 18 corresponden a Neuralgia occipital y/o del trigémino. Antes del implante del sistema de estimulación se realizó bloqueo nervioso occipital con anestésico local con el fín dedeterminar el componente cervicogénico del cuadro álgico. El procedimiento quirúrgico se ha realizado en dos tiempos. La valoración de la eficacia está basada en la variación, antes y después del implante del sistema, de los siguientes parámetros: dolor continuo, dolor en las crisis y número de crisis, descanso nocturno, funcionalidad, actividad social y laboral, satisfacción del paciente, reducción del tratamiento farmacológico y estado emocional. Resultados: Los pacientes corresponden a 25 mujeres y 9 hombres, de 51,2 años de edad media (R. 29-80). Presentaban dolor continuo y en 27, además, se manifestaban crisis con agudización sintomática de gran severidad. Todos los pacientes necesitaban tratamiento farmacológico analgésico (media de 4,4fármacos por paciente). En todos los pacientes habían fracasado otras alternativas terapéuticas. El tiempo medio de evolución del dolor era de 98,9 meses (R. 5-360) (...)(AU)

Introduction: The peripheral cervical-occipital extraspinal electrical stimulation with an implanted system, is a little aggressive technique that can achieve good results in patients with refractory neurophatic pain localized in the cephalic and facial region. Thirty four patients with long-evolving, persistent, severe, uncontrolled pain of different ethiologies, localized in the cervical facial region, for whom other therapy options were exhausted, were treated with unilateral or bilateral cervical occipital electrical stimulation in the pain unit of the Zaragoza Clinic Hospital. Material and Method: Thirty four patients were treated from June 2002 to February 2008, fourteen of which were diagnosed with transformed migraine; two suffered from cluster headache and eighteen had occipital and/or trigeminal neuralgia. Before the neurostimulation system was implanted, an occipital nerve block was performed with local anesthetic to establish the cervicogenic component in the pain. The surgical procedure was performed in two stages. The treatment effectiveness assessment was made on the basis of the variation of the following parameters before and after the implant: ongoing pain, pain during the crisis, number of crisis events, overnight rest, functioning, social and laboral activity, patient satisfaction, drug therapy reduction and emotional status. Results: The participants were 25 female patients and 9 male patients with an average age of 51,2 (R. 29-80). They suffered from ongoing pain, and 27 of them also experienced crisis events with a very severe agudization of symptoms. All the patients needed pharmacological treatment with analgesics (average of 4,4 drugs per patient). Other treatment options had failed in all these patients. The mean time of pain evolution was 98,9 months (R. 5-360)...(AU)
