Coagulative necrotic pituitary adenoma apoplexy: A retrospective study of 21 cases from a large pituitary center in China.

PURPOSE: Coagulative necrotic pituitary apoplexy (CNPA) is a clinical entity with unique intraoperative and histopathological manifestations. We aimed to improve the knowledge of this rare disease through the largest case series published to date. METHODS: A retrospective review of 21 CNPA patients was performed from among 5095 patients who underwent surgery for pituitary adenomas at a single institution between January 2009 and June 2017. The demographic, clinical, endocrine, neuroimaging, intraoperative, and histopathological findings, management and prognosis were summarized. RESULTS: Headache was the most common symptom that was observed in 21 patients, followed by visual disturbances (17/21, 81.0%), nausea and vomiting (16/21, 76.2%), electrolyte disturbance (13/21, 61.9%), and oculomotor palsies (10/21, 47.6%). Hypopituitarism with at least one anterior pituitary deficiency, especially panhypopituitarism (10/21, 47.6%), was present in 81.0% of patients. Most patients (81.0%) showed typical MRI appearances. All 21 patients underwent transsphenoidal surgery (TSS), and 16 patients had total tumor resection demonstrated by postoperative MRI. Cottage cheese-like necrosis was observed in 16 patients (76.2%) intraoperatively. Histopathology showed large areas of pink, acellular, coagulative necrotic areas in the central zone, and a pseudocapsule in the border zone. After follow-up for 4.3 ± 2.3 years, only 28.6% of patients still suffered from corticotropic deficiency, and 9.5% of patients had gonadotropic deficiency. These patients were administered the appropriate corresponding hormones for life. CONCLUSIONS: CNPA can be correctly diagnosed preoperatively by typical clinical and MRI characteristics. Early surgery combined with hyperbaric oxygen therapy early postoperatively usually yields satisfactory endocrine and neuro-ophthalmic outcomes.

Sunlight exposure: Do health benefits outweigh harm?

Vitamin D is a fat-soluble vitamin whose levels within the body are elevated following sunlight exposure. Numerous studies have shown that sunlight exposure can provide protection to a wide variety of diseases, ranging from different types of tumors to hypertension to type 1 diabetes to multiple sclerosis. Moreover, studies have shown that avoiding sunlight may influence the initiation and progression of some of these diseases. Avoidance of sunlight, coupled with the inclination towards consuming supplements, is becoming the primary choice to obtain vitamin D. The purpose of this article is to present evidences from published literature, to show that the expected benefits of vitamin D supplements are minimized by the potential risk of cardiovascular events and beyond. Since hypovitaminosis D status usually reflects reduced sunlight exposure, the obvious primary replacement should be safe sunlight exposure, and not exogenous supplements.

Impact of osteopathic treatment on pain in adult patients with cystic fibrosis--a pilot randomized controlled study.

BACKGROUND: Pain is a common complication in patients with cystic fibrosis (CF) and is associated with shorter survival. We evaluated the impact of osteopathic manipulative treatment (OMT) on pain in adults with CF. METHODS: A pilot multicenter randomized controlled trial was conducted with three parallel arms: OMT (group A, 16 patients), sham OMT (sham treatment, group B, 8 patients) and no treatment (group C, 8 patients). Medical investigators and patients were double-blind to treatment for groups A and B, who received OMT or sham OMT monthly for 6 months. Pain was rated as a composite of its intensity and duration over the previous month. The evolution of chest/back pain after 6 months was compared between group A and groups B+C combined (control group). The evolution of cervical pain, headache and quality of life (QOL) were similarly evaluated. RESULTS: There was no statistically significant difference between the treatment and control groups in the decrease of chest/back pain (difference = -2.20 IC95% [-4.81; 0.42], p = 0.098); also, group A did not differ from group B. However, chest/back pain decreased more in groups A (p = 0.002) and B (p = 0.006) than in group C. Cervical pain, headache and QOL scores did not differ between the treatment and control groups. CONCLUSION: This pilot study demonstrated the feasibility of evaluating the efficacy of OMT to treat the pain of patients with CF. The lack of difference between the group treated with OMT and the control group may be due to the small number of patients included in this trial, which also precludes any definitive conclusion about the greater decrease of pain in patients receiving OMT or sham OMT than in those with no intervention. TRIAL REGISTRATION: ClinicalTrials.gov NCT01293019.

Use of complementary and alternative medicine by a sample of Turkish primary headache patients.

OBJECTIVE: Complementary and alternative medicine (CAM) is increasingly being used as adjunctive treatment in primary headache syndromes in many countries. In the Turkish population, no epidemiologic data have been reported about awareness and usage of these treatments in patients with headache. METHODS: One hundred and ten primary headache patients attending three headache clinics completed a questionnaire regarding their headaches, the known modalities and the use and effect of CAM procedures for their headaches. RESULTS: The mean age of the patients was 34.7±9.6 years (32.8-36.5). Almost two-thirds of patients had completed high school and university, and one-third of patients were housewives. Migraine without aura (45.5%) was the most frequently diagnosed type of headache followed by migraine with aura (19.1%) and tension-type headache (18.2%). In 43.6% of the patients, headache frequency was 5-10 per month. The most frequently known CAM modalities were massage (74.5%), acupuncture (44.5%), yoga (31.8%), exercise (28.2%), psychotherapy (25.5%), and rosemary (23.6%). The most frequently used CAM treatments were massage (51%) and exercise (11%). Only massage was reported to be beneficial in one-third of the primary headache patients; the other modalities were not. CONCLUSION: Our findings suggest that the subgroup of primary headache patients in Turkey seek and use alternative treatments, frequently in combination with standard treatments. Neurologists should become more knowledgeable regarding CAM therapies; further randomized and controlled clinical researches with large sample sizes are needed.

Neurostimulation for primary headache disorders, part 1: pathophysiology and anatomy, history of neuromodulation in headache treatment, and review of peripheral neuromodulation in primary headaches.

Neurostimulation for primary headaches is being increasingly utilized as a treatment modality. Use of neuromoduation has generated multiple case reports as well as some controlled studies. This article is the first of 2 systematic reviews of available data regarding neurostimulation for primary headache conditions. The pathophysiology, relative anatomy, theoretical mechanisms, and history of neurostimulation for primary headache are covered in this section, Part 1 of 2. The literature regarding peripheral neurostimulatory targets is also reviewed in Part 1. These peripheral targets include: percutaneous nerves, transcranial holocephalic, occipital nerves, auriculotemporal nerves, supraorbital nerves, cervical epidural, and sphenopalatine ganglia. Part 2 will focus on central stimulation, covering vagus nerve, and deep brain stimulation. Part 2 also contains an overall analysis of efficacy, safety, cost, patient selection, and suggestions for further study based on available evidence.

Volume changes of corpus striatum, thalamus, hippocampus and lateral ventricles in posttraumatic stress disorder (PTSD) patients suffering from headaches and without therapy.

BACKGROUND AND AIM: In the present study, we have hypothesized that volume changes of the caudate nucleus, putamen, globus pallidus, hippocampus, thalamus, and lateral ventricle in newly-diagnosed, male PTSD patients without therapy are more pronounced in those with headaches. To confirm or reject our hypothesis, we have undertaken an extensive study of forty-nine PTSD patients. PATIENTS AND METHODS: To confirm or reject our hypothesis, we have undertaken an extensive study of forty-nine PTSD male patients that underwent MRI scanning immediately upon admittance for the treatment. Based on headache frequency, they were classified into three groups: group 1 included patients with headaches at least twice a week; group 2 consisted of patients with headaches less than twice a week; and group 3 consisted of patients without headaches. All MRI scans underwent software-based volume compute and statistical processing. RESULTS: 39 out of 49 patients with PTSD suffered from headaches. Bilaterally, volume decreases were noted in groups 1 and 2 compared to group 3 for the caudate nucleus, putamen, hippocampus and lateral ventricle. Differences in globus pallidus and thalamus among groups appeared to be insignificant. CONCLUSION: The present study revealed a bilateral volume decrease of the caudate nucleus, putamen and hippocampus in PTSD male subjects without therapy. Intensity of volume alterations correlated with Hamilton's depression rating score; regression analysis uncovered correlated changes in the caudate nucleus, putamen and hippocampus, and an inverse correlation with the volume of the lateral ventricle in the PTSD patients.

How healthy are chronically ill patients after eight years of homeopathic treatment?--Results from a long term observational study.

BACKGROUND: Homeopathy is a highly debated but often used medical treatment. With this cohort study we aimed to evaluate health status changes under homeopathic treatment in routine care. Here we extend former results, now presenting data of an 8-year follow-up. METHODS: In a prospective, multicentre cohort study with 103 homeopathic primary care practices in Germany and Switzerland, data from all patients (age >1 year) consulting the physician for the first time were observed. The main outcome measures were: The patients' perceived change in complaint severity (numeric rating scales from 0 = no complaint to 10 = maximal severity) and quality of life as measured by the SF-36 at baseline, and after 2 and 8 years. RESULTS: A total of 3,709 patients were studied, 73% (2,722 adults, 72.8% female, age at baseline 41.0 +/- 12.3; 819 children, 48.4% female, age 6.5 +/- 4.0) contributed data to the 8-year follow-up. The most frequent diagnoses were allergic rhinitis and headache in adults, and atopic dermatitis and multiple recurrent infections in children. Disease severity decreased significantly (p < 0.001) between baseline, 2 and 8 years (adults from 6.2 +/- 1.7 to 2.9 +/- 2.2 and 2.7 +/- 2.1; children from 6.1 +/- 1.8 to 2.1 +/- 2.0 and 1.7 +/- 1.9). Physical and mental quality of life sores also increased considerably. Younger age, female gender and more severe disease at baseline were factors predictive of better therapeutic success. CONCLUSION: Patients who seek homeopathic treatment are likely to improve considerably. These effects persist for as long as 8 years.

Chronic subdural hematoma in capoeira sport.

Chronic subdural hematomas in young people is extremely rare and has some provoking factors such as V-P shunts, arachnoid cyst, anticoagulant drug usage, vigorous sports and coagulopathies. A static or dynamic mechanical load is almost always delivered to skull associated with either mild or severe head trauma. A 25-year old-man who was previously healthy has complained of intermittent headache for six months. He had been interested in capoiera (Brazilian exciting sport) for two years and has had no any evidence of head injury. After admission, he was operated immediately because of chronic subdural hematoma. We report a patient who is the first chronic subdural hematoma in the literature due to playing capoeira.

Reversible cerebral angiopathy: efficacy of nimodipine.

Reversible cerebral angiopathy (RCA) is responsible for disabling headache and potential stroke complications. Most patients respond poorly to analgesics. We describe four patients with typical RCA whose headache rapidly disappeared after IV nimodipine treatment was initiated.

Effect of posterior temporal-parietal hematoma on orbital frontal chemistry in relation to a cognitive and anxiety state: a combined 1H-MRS and neuropsychological study of an unusual case as compared with 16 healthy subjects.

The authors report the unusual case of a 58-year-old woman (MJP) suffering from left temporal throbbing headache, associated with confusion. Magnetic resonance imaging showed a 5 x 3 x 2 cm hematoma at the left posterior temporal--parietal junction (PTPJ). Repeated MRI of MJP's brain performed during a 4-month follow-up period showed decrease in hematoma size (2.3 x 1.5 x 1) with evidence for development of encephalomalacia and resorption of blood products involving the area of hemorrhage. MJP had mild transcortical sensory aphasia characterized by difficulty with reading and processing, with semantic paraphasic errors while speaking and some difficulty with repetition. MJP had remained normotensive and seizure free, on Vasotec therapy and Dilantin prophylaxis. An in vivo proton magnetic resonance spectroscopy (1H-MRS) performed during an 8-month follow-up period showed reduced concentration for N-acetyl aspartate (NAA) by 19.3% (F=4.09, P<0.04), and myo-inositol by 32.0% (F=5.16, P<0.02) in the left orbital frontal cortex (OFC) as compared with 16 healthy subjects (age- and sex-matched). Cognitive tests (the Wechsler abbreviated scale of intelligence (WASI) and the Stroop color--word interference) showed a significant impairment suggesting involvement of higher-order cognitive functioning (memory, learning, and general intelligence) and attentional system. The Spielberger state-trait anxiety inventory (STAI) showed increased anxiety at the moment of the current examination and decreased tendency to be anxious over a long period of time. The Beck Anxiety and Depression Inventory revealed minimal anxiety and mild to moderate levels of depression. It is hypothesized that the PTPJ hematoma triggered long-distance pathways linking PTPJ area and frontal lobe, including OFC, which resulted in abnormal chemical changes in the left OFC and in cognitive tests impairment, and in long-term anxiety state changes.
