Manejo da dor inguinal crônica pós-hernioplastia (inguinodinia)

A dor inguinal crônica pós-herniorrafia é uma situação preocupante, pois aproximadamente 10% dos pacientes submetidos à hernioplastia inguinal apresenta os sintomas, que com frequência limita a capacidade física. A etiopatogênese está relacionada a uma periostite do púbis (dor somática) e mais frequentemente à lesão nervosa (dor neuropática). É importante distinguir clinicamente entre os dois tipos de dor, pois o tratamento pode ser diferente. O médico deve estabelecer uma rotina diagnóstica e de tratamento, sendo que a maior parte dos pacientes necessitarão de terapêutica cirúrgica. A prevenção desta condição é de grande importância e pode levar a uma menor incidência da síndrome. Algumas medidas são fundamentais, como evitar pontos ou clipes no periósteo do púbis, usar criteriosamente as próteses e identificar os nervos da região inguinal. Esta última medida é certamente a mais importante na prevenção da dor crônica e implica em conhecimento profundo da anatomia e o uso de uma técnica aprimorada.

O uso da prótese na correção das hérnias da parede abdominal é um avanço, mas o seu uso indiscriminado, um abuso

The objective is to alert the surgeon about the indiscriminate use of synthetic prosthesis in the correction of inguinal and incisional hernias. The authors provide a brief history of surgery on hernias and a review of the literature, showing the importance of classifying inguinal hernias to fit the type of surgical correction with the defect found, abstaining from treating all hernias, with the same type of surgical procedure. In our opinion, small indirect inguinal hernias (type 1 and 2 of Gilbert) and hernias in women must not, in general, be treated with prostheses. The synthetic material should be reserved for direct and large indirect hernias. Even so, this attitude, besides determining a higher cost for the procedure, can lead to important complications such as infection, rejection, fistula formation, chronic pain, alterations in spermatogenesis and the possibility of carcinogenesis, according to more recent reports. The physiology and anatomy of the abdominal wall should be considered when dealing with incisional hernia corrections, where the surgeon can choose among many techniques to correct those defects, and in selected cases, utilize synthetic material. We conclude that although the use of biomaterials has constituted a great advance in surgery for abdominal wall hernia corrections because they decrease recurrences, and permit treatment of large abdominal hernias, the indiscriminate prosthesis usage is an abuse, and it can determine many serious complications, certainly avoidable with a well indicated non mesh technique .

Antinociceptive profile of (-)-spectaline: A piperidine alkaloid from Cassia leptophylla

The antinociceptive activity of (-)-spectaline (1), a piperidine alkaloid isolated from Cassia leptophylla Vog. (Leguminosae), was investigated. We have also studied the acute oral toxicity of 1 in mice and it did not show any signals of toxicity in doses lower than 400 mumol/kg. The antinociceptive effect of 1 was evaluated on chemical (acetic acid, formalin and capsaicin) and thermal (hot plate and tail flick) pain models in mice, using classical standard drugs. Dipyrone ID50 = 14.68 mumol/kg (4.8 mg/kg), in-domethacin ID50 = 0.78 mumol/kg (0.28 mg/kg) and (-)-spectaline ID50 = 48.49 mumol/kg (15.75 mg/kg), all produced a significant inhibition of acetic acid-induced abdominal writhing in mice. (-)-Spectaline was inactive in the hyperalgesic model of formalin and did not show any central analgesic activity (hot plate and tail flick models). In the capsaicin-induced neurogenic pain model, (-)-spectaline presented an important inhibitory effect with an ID50 = 20.81 mug/paw and dipyrone ID50 = 19.89 mug/ paw. The ensemble of results permitted us to identify 1 as an antinociceptive compound. The mechanism underlying this antinociceptive effect of 1 remains unknown, but the results suggest that such an effect could be related to pathways associated to vanilloid receptor systems.

Background: Canine hip dysplasia (HD) is characterized by hip joint laxity and subluxation. It is the most common cause of osteoarthritis in dogs, especially in larger breeds. Its management includes nutritional supplements, nonsteroidal anti-inflammatory drugs, physical therapy, acupuncture or surgical procedures. Implantation of gold beads in acupuncture points and trigger points around a joint has been used in the treatment of osteoarthritis in dogs for at least 30 years. Gold bead implants(GBI) acts as continuous acupuncture stimulation and trigger point treatment in canine HD with long lasting results. Electrophysiological investigations of trigger points reveal dysfunctional muscle spindles which indicate that the electrical activity of active loci arises from extrafusal motor endplates.Case: This is a report on the use of acupuncture and GBI for bilateral HD in a nine year old female German Shepherd. The patient has a HD non-responsive to anti-inflammatory drugs and was unable to stand up or walk by its own. Radiographs showed marked dysplasia, significant subluxation with the femoral head partly out of a shallow acetabulum and massive secondary arthritic bone changes, mainly on the right side. The animal was submitted to eight acupuncture sessions with seven days interval. After the first acupuncture session the use of NSAID was interrupted. After eight weeks the dog was considered rehabilitated and underwent GBI in acupoints and trigger points as maintenance treatment. During the one-year follow-up period the improvement remained unchanged with no need of analgesics.Discussion: It has been suggested that acupuncture or GBI can treat the chronic pain resulting from osteoarthritis induced by HD. According to AP theory, GBI is permanent and long-lasting acupoint stimulation. Moreover, the method is inexpensive, quick and easy to perform, with no postoperative pain or need of exercise restriction. Although gold is extremely corrosion-resistant, the surface of the gold implants stimulates a reaction from the immune system causing an oxidative liberation of gold ions with anti-inflammatory actions. It is well known that gold ions are effective inhibitors of the respiratory burst of neutrophils and monocytes and the proliferation of lymphocytes. These findings suggest that gold implantation, on a local scale, mimics the anti-inflammatory and pain-relieving effect of drugs with chemically bound gold ions. The relatively slow speed of the process results in a limited liberation of gold ions securing that they are taken up almost exclusively by cells close to the implant. The nine year old female German shepherd had a positive response to acupuncture with pain relieve and locomotor rehabilitation. For the nine year old female German shepherd previous acupuncture sessions to GBI resulted in no post-implant worsening period. Indeed, the association acupuncture/GBI does not have the anti-inflammatory drugs undesirable effects and brings long lasting results. In conclusion, GBI therefore should be considered for canine HD when conservative or medical treatments fail to give the desired effect.

ALGIAS CRANIOFACIAIS - UM ROTEIRO PARA O EXAME FISICO DIRIGIDO

Craniofacial pain is a frequent challenge for the physician anamnesis with the goal to obtain specific and useful information about symptoms in craniofacial pain. It can be improved by identifying aching points. In the article, the authors present a practical and specific schedule for physical examination to be applied in patients with chronic pain. This specific schedule, which has proved useful in detecting the exact anatomic sites of pain, has a sequence ordered which includes palpation and inspection of muscles, nerves and arteries.

Abuso sexual, transtornos mentais e doencas fisicas

Objective: to review and describe the different organic and psychic consequences of sexual abuse. Methodology: 71 papers were sorted in a ten-year literature search (1987-1997) in MedLine and Lilacs (South American Literature Index), besides 14 books in the subject. Results: sexual abuse is much less frequent (or less reported) in Brazil: 7% of the population, while in the USA the prevalence is 12.9% to 28% of women and 2% to 9% of men. Results showed women being more frequently sexually abused but less differences in physical abuse were found between genders. There was a significant association between sexual abuse and the following: eating disorders, depression, irritable bowel, chronic pain (mainly pelvic), neurological, rheumatic and venereal disorders. This association was not observed in chronic constipation, Chron disease and dissociative disorders. Conclusions: although it is important to think of sexual/physical abuse as a predisposing factor to several illnesses, caution is necessary specially in cultures with different moral and ethical values. Research in this subject in Brazil should be conducted with patients in treatment, using control groups, in order to take advantage of the existing rapport. It would be also quite important to separate acute and chronic abuse effects, as well as getting to know the meaning of the experienced abuse to each person.

Injeção subaracnóidea inadvertida de corticoíde em tratamento de dor crônica da coluna lombar. Relato de caso

BACKGROUND AND OBJECTIVES: Before epídural steroids were used in chronic lumbar pain, subarachnoid injection of these agents was the treatment of choice. Although still preconized by some authors, this technique may lead to severe complications with neurological sequelae. This report aimed at describing a case of accidental subarachnoid injection of steroid associated to local anesthetics during epidural puncture to treat lumbar pain. CASE REPORT: Male patient, 46 years old, followed byneuro-surgery for presenting right sciatic pain for 9 month, refractory to clinical treatment due to L 4-L 5 disk protrusion confirmed by CT scan, without neurological deficit. Epidural puncture for pain treatment was performed in L 4-L 5 with 17G needle and 10 mL solution were injected containing 4 mL of 0.25% bupivacaine, 80 mg methylprednisolone and 4 mL of 0.9% saline. Although there has not been CSF reflux, 5 minutes after injection there were sensory block in T 4 and motor block in T 6, associated to blood pressure and heart rate decrease. CONCLUSIONS: Accidental subarachnoid injections with the association of steroids for pain relief may cause adverse effects. There are several risks, varying from mild transient symptoms to nervous injuries, including spinal cord injuries. Our patient had no sequelae from the accidental subarachnoid injection, probably because it has been a single injection.

Evaluation of adverse effects of long-term oral administration of carprofen, etodolac, flunixin meglumine, ketoprofen, and meloxicam in dogs

Objective - To evaluate adverse effects of long-term oral administration of carprofen, etodolac, flunixin meglumine, ketoprofen, and meloxicam in dogs. Animals - 36 adult dogs. Procedures - Values for CBC, urinalysis, serum biochemical urinalyses, and occult blood in feces were investigated before and 7, 30, 60, and 90 days after daily oral administration (n = 6 dogs/group) of lactose (1 mg/kg, control treatment), etodolac (15 mg/kg), meloxicam (0.1 mg/kg), carprofen (4 mg/kg), and ketoprofen (2 mg/kg for 4 days, followed by 1 mg/kg daily thereafter) or flunixin (1 mg/kg for 3 days, with 4-day intervals). Gastroscopy was performed before and after the end of treatment. Results - For serum γ-glutamyltransferase activity, values were significantly increased at day 30 in dogs treated with lactose, etodolac, and meloxicam within groups. Bleeding time was significantly increased in dogs treated with carprofen at 30 and 90 days, compared with baseline. At 7 days, bleeding time was significantly longer in dogs treated with meloxicam, ketoprofen, and flunixin, compared with control dogs. Clotting time increased significantly in all groups except those treated with etodolac. At day 90, clotting time was significantly shorter in flunixin-treated dogs, compared with lactose-treated dogs. Gastric lesions were detected in all dogs treated with etodolac, ketoprofen, and flunixin, and 1 of 6 treated with carprofen. Conclusions and Clinical Relevance - Carprofen induced the lowest frequency of gastrointestinal adverse effects, followed by meloxicam. Monitoring for adverse effects should be considered when nonsteroidal anti-inflammatory drugs are used to treat dogs with chronic pain.
