Trigeminal neuralgia. Surgical treatment by microvascular decompression of the trigeminal nerve root.

The surgical management of trigeminal neuralgia has always been less than ideal. Evidence accumulated over the last 10 years suggests that the condition is caused by vascular compression of the trigeminal nerve root at the brain stem. Removal of this compression by means of micro-neurosurgical techniques has so far been very effective in relieving the pain of trigeminal neuralgia while maintaining normal facial sensation. A series of 10 patients who underwent this procedure is presented. All patients lost their pain, and during the follow-up period of six to 18 months, there have been no recurrences. This experience further demonstrates that the microvascular decompression is a very useful procedure in selected patients.

[Treatment of essential facial neuralgia by selective thermocoagulation of Gasser's ganglion].

The authors report their experience in the treatment of essential facial neuralgia by differential thermocoagulation of the gasserian ganglion. This method is based upon the fact that small pain fibres (A delta and C) are more sensitive to warmth than large touch fibres. Thus progressive and controlled thermocoagulation of the trigeminal ganglion makes it possible to obtain selective destruction of the small fibres (analgesia without anaesthesia). 76 patients were treated using the method, and in 75 cases the symptoms of neuralgia disappeared immediately. Mortality is nil and morbidity insignificant other than the effects on the trigeminal nerve. The most serious complication (Approximately 10% of cases) was that of marked hypoaesthesia, rather than pure analgesia, in the coagulated area.

[Arthrodesis of the cervical vertebrae by the anterior approach for the treatment of cervicobrachial neuralgias of discal origin (author's transl)].

Cervicobrachial neuralgia of discal origin can be improved by a simple operation: excision of the pathological disc followed by an intercorporeal arthrodesis by the anterior approach, using an implanted graft without the use of any osteosynthetic material. The authors performed 20 such operations, using this method as described by Cloward, with very encouraging results. The selection of patients suitable for surgery, however, depends on strict criteria: isolated definite discal pathology, usually post-traumatic, suspected clinically and confirmed by a standard radiograph and gas myelography; finally, conclusive proof of immobilisation. The simple nature of the operation, the rapidity with which it can be performed, the short period of hospitalization and professional care required, and the absence of sequelae, are several factors which suggest that this surgical procedure should become the standard therapy for cervicobrachial neuralgias, as it is for the surgical cure of lumbar disc hernias. The introduction of more precise and comfortable radiographic methods, such as the scanner and metrizamide myelography, will ensure that this functional type of surgery becomes more economical and responds to the individual needs of the patients.

Glossopharyngeal neuralgia, asystole, and seizures.

Glossopharyngeal neuralgia, asystole, and seizures occurred in a patient with an internal carotid occlusion and external carotid stenosis. Swallowing was the triggering mechanism for these events. Mechanical stimulation of the pharynx failed to reproduce the symptoms. An ischemic injury to the glossopharyngeal nerve in the region of the jugular foramen that resulted in an artificial synapse is the proposed etiology.

Periodic migrainous neuralgia: a cause of dental pain.

The clinical findings in thirty-five cases of periodic migrainous neuralgia (PMN) are given. Typical case histories are used to illustrate the fact that the condition may mimic dental pain. The nomenclature and association of the condition with migraine are briefly discussed, and a plea is made that the condition always be considered in cases of facial pain, when other clinical features of the disease are present, in order to save needless loss of teeth and delay in treatment.

Modern trends in surgical treatment of trigeminal neuralgia.

From 1955 to July 1978, 560 patients suffering from trigeminal neuralgia, who had not responded to medical treatment underwent various alternative procedures. Considering some of these to be out of date, some as showing too high a number of relapses and some as having potentially unjustified risks in an affection in itself not fatal, the authors report only the results observed in a series of 175 patients operated on by retrogasserian rhizotomy according to Frazier (1931), and the results of a series of 184 patients treated by controlled thermocoagulation according to Sweet and Wepsic (1974).

Glossopharyngeal neuralgia with syncope.

Thirty-two cases of glossopharyngeal neuralgia complicated by syncope, cardiac arrhythmias or convulsions, singly or together, have been reported in the world literature. A further case is described and the clinical features of these thirty-three are reviewed. It is recommended that treatment should be undertaken as a matter of urgency. In the first place, Carbamezapine, with often the addition of Atropine, may prove effective. However, surgical intervention appears to give a better chance of permanent relief. Four alternative methods of surgery are discussed and the cervical or the intracranial approach recommended. Surgery should not be delayed in patients who fail to respond to medical treatment or in whom recurrence of symptoms occurs.

Saphenous neuralgia: a complication of vascular reconstructions below the inguinal ligament.

Although relatively frequent in our experience saphenous neuralgia (SN) is not usually reported as a complication of vascular operations below the inguinal ligament. In 55 patients undergoing extended deep femoral angioplasty (EDFA, n = 28) and femoropopliteal bypass graft (FPBG, n = 27) special attention was paid to incidence and severity of postoperative SN. Severe early postoperative SN was seen in 8/28 patients with EDFA and in 6/27 with FPBG. Milder SN was seen in 10 more patients with EDFA, and 3 other developed SN many months after surgery. The milder forms of SN and late SN were not encountered after FPBG. SN usually improved with the passage of time, and at last follow-up averaging 18 months for EDFA and 33 months for FPBG there remained only 23 patients with mild SN (15 after EDFA and 8 after FPBG). The etiology of SN appears to be trauma to the nerve sustained during operation. Age, sex, diabetes, or the addition of lumbar sympathectomy to the vascular operation did not affect the risk of sustaining early postoperative SN. Increased awareness of this complication may help to understand its pathophysiology better, and possibly to decrease its incidence.

Antibodies against herpes simplex virus type 1 subunit antigens in patients with trigeminal neuralgia and controls.

Serum IgG antibody levels against herpes simplex virus (HSV) type 1 subunit (capsid, envelope, and excreted) antigens detected with radioimmunoassay were compared in 25 patients with trigeminal neuralgia and their age- and sex-matched controls. No significant differences were found between the patients and controls, either in the distribution of the antibody titers or in the mean titers against any of the subunit antigens tested. In 6 patients HSV antibody titers were tested before and after trigeminal root section; no significant changes were observed.

Sensory functions in chronic neuralgia.

Eleven patients with sustained neuralgia, in most cases after traumatic nerve lesion, were subjected to quantitative sensory testing with thermal and non-noxious mechanical stimuli. Measurements were made in the pain area and at a homologous site on the contralateral normal side. All patients were hypoaesthetic with raised thresholds for warm and cold or touch, or both. Thermal pain thresholds were also raised in some patients but lowered in others indicating hypersensitivity of the nociceptor system or dysaesthesia for thermal input. In six patients single mechanical stimuli produced a painful response above the touch detection threshold. Reaction time measurements indicated that this painful response to suprathreshold mechanical pulses was measured by magnitude estimation as a function of stimulus amplitude. The results were fitted by power functions, as in normal skin, but with steeper slopes on the abnormal side. Suprathreshold hyperaesthesia (recruitment) may exist in the presence of normal threshold functioning.

Application of stereotactic principles to the treatment of trigeminal neuralgia.

The application of neuroanatomical and neurophysiological principles to the functional surgery of the trigeminal nerve is discussed. Particular attention has been directed toward correlating the three-dimensional anatomical features of the trigeminal nerve and the surrounding structures to the two-dimensional radiograph of this same region. In this regard, 20 trigeminal nerves, including the surrounding neurovascular structures from 10 cadaver sphenoid blocks, were examined. Measurements of the third, fourth and sixth cranial nerves in relation to the profile of the clivus were made from lateral radiographs of the sphenoid blocks. The position of the internal carotid artery in relation to these structures was also noted. These neurovascular relationships are of clinical importance when using the percutaneous thermocoagulation technique for the treatment of trigeminal neuralgia.

Exploring the causal relationship between plasma proteins and postherpetic neuralgia: a Mendelian randomization study.

BACKGROUND: The proteome represents a valuable resource for identifying therapeutic targets and clarifying disease mechanisms in neurological disorders. This study investigated potential causal relationships between plasma proteins and postherpetic neuralgia (PHN). METHODS: We conducted a two-sample Mendelian randomization (MR) analysis using genome-wide association study (GWAS) summary statistics from the Decode Genetics dataset (4,907 plasma proteins) and the FinnGen database (490 PHN cases and 435,371 controls). Instrumental variables (IVs) were selected based on relevance, independence, and exclusivity. Causal associations were assessed using inverse-variance weighted (IVW), MR-Egger regression, simple mode, weighted mode, and weighted median methods. Sensitivity analyses, including leave-one-out tests, evaluated result robustness, while colocalization analysis examined shared causal variants between traits. RESULTS: Eight plasma proteins showed significant associations with PHN (PFDR < 0.05). Higher levels of ATRN, PIANP, and CD48 correlated with increased PHN risk, whereas elevated KIR2DL5A, GPI, SEMG2, EIF4B, and HFE2 levels were associated with reduced risk. Sensitivity analyses supported these findings and excluded genetic pleiotropy as a major confounding factor. Colocalization analysis did not detect shared causal variants (PPH4 < 0.8). CONCLUSION: These results suggest a potential causal role for eight plasma proteins in PHN pathogenesis. While these proteins may serve as biomarkers or therapeutic candidates, further validation is required. This study advances understanding of PHN pathophysiology and supports future investigations into diagnostic and therapeutic strategies.

A Standardized Nursing-Led Protocol Integrated Pain, Sleep, Medication Adherence, and Symptom Management in Postherpetic Neuralgia.

Postherpetic neuralgia (PHN) is a persistent neuropathic pain condition after herpes zoster that frequently coexists with sleep disturbance, medication-related problems, and fluctuating symptoms. This study evaluated whether a standardized nursing-led protocol could improve multidimensional short-term outcomes beyond usual care. In this prospective, parallel-group randomized controlled trial, 128 adults with PHN were allocated 1:1 to usual care or usual care plus an eight-week protocol integrating structured pain assessment, sleep monitoring, medication-adherence support, and rule-based digital symptom monitoring. The primary outcome was the between-group difference in change in Numeric Rating Scale (NRS) pain score from baseline to Week 8. Secondary outcomes included Pittsburgh Sleep Quality Index (PSQI), MMAS-8 medication adherence, symptom burden, pain-related nocturnal awakenings, breakthrough pain, rescue analgesic use, adverse events, rule-based alerts, and nursing satisfaction. Week-8 data were available for 116 participants (57 usual care; 59 protocol). Mean NRS scores decreased from 7.19 &#xb1; 1.08 to 4.82 &#xb1; 1.53 in the usual-care group and from 7.28 &#xb1; 1.05 to 3.24 &#xb1; 1.28 in the protocol group. An NRS reduction of at least 2 points occurred in 49.1% and 76.3% of participants, respectively. The protocol group also showed larger improvements in PSQI, MMAS-8, symptom burden, and nocturnal awakenings, with fewer breakthrough-pain episodes and less rescue-analgesic use. These findings support further evaluation of the standardized nursing-led protocol in preregistered multicenter trials with intention-to-treat analyses and longer follow-up.

[Dental aspects of atypical neuralgia in the maxillofacial region (author's transl)].

The complicated anatomy of the masticatory system with its coordinated functional elements offers a multitude of noxae for atypical neuralgias. More specifically, affections of the pulp, apical periodontopathies with cyst formation, impacted teeth, aggressive osteopathies and malignant growth come into consideration. In addition, dysfunctional unions must be borne in mind. The styloid syndrome also deserves attention. Because of this causal complex the discovery of other puzzling painful conditions needs dental investigation.
