Perceived self-image in adolescent idiopathic scoliosis: an integrative review of the literature

Objective: To learn about the experiences of adolescents diagnosed with idiopathic scoliosis. Method: Integrative review of the literature published within a specified time frame. Results: For both sexes, the predominant clinical symptom of this condition appears to be the negative effect that the deformity exerts on perceived self-image. Quantitative studies used numerical scores to assess perceptions of body image but did not analyse emotional aspects. Patients treated surgically were found to have a better self-image than patients treated with a brace. Quality of life was improved by a reduction in the magnitude of the curve. Conclusion: Spinal deformity exerts a psychological effect on adolescent girls.


Implementation of a perioperative management protocol for patients undergoing orthopedic surgery

OBJECTIVE: To evaluate the initial results after the implementation of perioperative protocol in patients over 60 years of age undergoing surgical treatment for femur fractures.METHODS: We conducted a prospective study of patients older than 60 years who were hospitalized with femur fracture. They were operated under spinal anesthesia and analgesia by lumbar plexus blockade. Data evaluation was performed before arrival in the operating room during surgery, in the post-anesthesia recovery room and in the ward the next morning of the operation.RESULTS: 105 patients underwent various types of surgical corrections of the femur. The hospital stay ranged from three to 86 days. Fasting ranged from 9h15min to 19h30mn. Hypotension occurred in 5.7%. The duration of motor blockade ranged from 1h45min to 5h30imn. Maltodextrin feeding ranged from 50min to 3h45min and the time spent in the post-anesthetic care unit ranged from 50 minutes to 4 hours. Onset of oral intake in the ward ranged from 4hto 8h15min. The duration of anesthesia ranged from 14 to 33 hours. No patient required a urinary catheter, nor was transferred to the ICU. All patients were able to be discharged on the first postoperative day.CONCLUSION: The use of a protocol to accelerate the postoperative period may reduce the fasting time, length of hospital stay and provide faster i discharge n elderly patients with femur fractures.

Transplantation of mononuclear cells from human umbilical cord blood promotes functional recovery after traumatic spinal cord injury in Wistar rats

Cell transplantation is a promising experimental treatment for spinal cord injury. The aim of the present study was to evaluate the efficacy of mononuclear cells from human umbilical cord blood in promoting functional recovery when transplanted after a contusion spinal cord injury. Female Wistar rats (12 weeks old) were submitted to spinal injury with a MASCIS impactor and divided into 4 groups: control, surgical control, spinal cord injury, and one cell-treated lesion group. Mononuclear cells from umbilical cord blood of human male neonates were transplanted in two experiments: a) 1 h after surgery, into the injury site at a concentration of 5 x 10(6) cells diluted in 10 µL 0.9% NaCl (N = 8-10 per group); b) into the cisterna magna, 9 days after lesion at a concentration of 5 x 10(6) cells diluted in 150 µL 0.9% NaCl (N = 12-14 per group). The transplanted animals were immunosuppressed with cyclosporin-A (10 mg/kg per day). The BBB scale was used to evaluate motor behavior and the injury site was analyzed with immunofluorescent markers to label human transplanted cells, oligodendrocytes, neurons, and astrocytes. Spinal cord injury rats had 25% loss of cord tissue and cell treatment did not affect lesion extension. Transplanted cells survived in the injured area for 6 weeks after the procedure and both transplanted groups showed better motor recovery than the untreated ones (P < 0.05). The transplantation of mononuclear cells from human umbilical cord blood promoted functional recovery with no evidence of cell differentiation.

Preliminar characterization of a new virus isolated from the spinal fluid of patients with meningitis in São Paulo, Brazil

A total of 138 patients with the age of 4 months to 57 years were attended in different hospitals of São Paulo State with aseptic meningitis. A probable new agent was isolated from the cerebrospinal fluid of 35 of 53 specimens examined. Replication of the agent with similar characteristics was detected by CPE produced in the MDCK cell line. Virus-like particles measuring about 40 nm in diameter were observed by negative staining electron microscopy. No hemaglutinating activity was detected at pH 7.2 by using either human, guinea pig, chicken and at pH ranged 6.0 - 7.2 with goose red blood cells. The agent was not pathogenic to newborn or adult mice. Virus infectivity as measured by CPE was sensitive to chloroform and not inhibited by BuDR, suggesting that agent is an enveloped virus with RNA genome.

A CASE REPORT OF INTRASPINAL PARACOCCIDIOIDOMYCOSIS

The authors report a case of paraplegia caused by a lumbar intraspinal paracoccidioidomycosis (PCM) granuloma. Clinical neurological diagnosis of a compressive spinal cord lesion was confirmed by spinal magnetic resonance imaging (MRI). Patient was submitted to surgery with total excision of the lesion. Histopathological analysis confirmed the diagnosis of PCM. Patient is on sulfamethoxazole/trimethoprim combined with fluconazole and is experiencing positive neurological recovery.

Actinomycosis affecting the spinal cord: a case report

Actinomycosis is a rare, chronic, suppurative, granulomatous infection caused by a group of gram-positive anaerobic bacteria belonging to the natural flora of the oral cavity and gastrointestinal and urogenital tracts. It may involve several organs. This case study refers to pulmonary actinomycosis with chest wall involvement and cord compression in a 29-year-old male who presented with fever, cough, hemoptysis, neck pain, and paresis and plegia of the lower limbs of 5-month duration.

Pheochromocytoma treated by laparoscopic surgery

OBJECTIVE: To evaluate the results of the laparoscopic technique in the treatment of adrenal pheochromocytoma. METHOD: Ten patients, 7 men and 3 women, between 10 and 67 years of age (mean 48) with pheochromocytoma underwent transperitoneal laparoscopic adrenalectomy and were evaluated retrospectively, based on clinical, laboratory, and pathological diagnosis. In all cases there was a solid unilateral adrenal tumor, 5 on the left side and 5 on the right side, whose greater diameter varied from 7 to 80 mm (mean 32). Nine of the 10 patients were chronically hypertensive or had already had hypertensive crises. One patient was normotensive, but presented metabolic alterations suggestive of adrenergic hyperfunction. RESULTS: No deaths occurred in this series. There were two (20%) conversions to open surgery, one due to venous bleeding and one due to the difficulty of dissection behind the vena cava in a patient presenting a partially retro-caval tumor. Surgical time in the 8 non-converted cases ranged from 70 to 215 minutes (mean 136). One patient (10%) received blood transfusion, and another (10%) presented two complications - acute renal failure and a subcutaneous infection. Both had been converted to open surgery. None of the non-converted cases was transfused or presented complications. Hospital discharge occurred between the 2nd and 11th post-operative day (mean 3). The pathological exam of the surgical specimens confirmed the diagnoses of pheochromocytoma in all 10 cases, one of them associated with an aldosterone-producing cortical tumor. CONCLUSIONS: Laparoscopic adrenalectomy for selected patients presenting pheochromocytoma is feasible and provides good results.

Cataract surgery: expectations of patients assisted during a community project in São Paulo, state of São Paulo, Brazil

OBJECTIVE: To identify social characteristics and expectations of individuals seen during a community project for the treatment of senile cataracts. Expected results from their eye surgery and its consequences to their quality of life were studied as well. METHODOLOGY: Cataract patients (visual acuity equal to or lower than 0.2 in the more superior eye) aged 50 years or over, were surveyed by means of interviews held during their visit at the Cataract Project in São Paulo city, State of São Paulo, Brazil, in 1999. RESULTS: The sample was composed of 331 subjects of low socioeconomic level ranging in age from 50 to 97 years (average = 71.8 years). Expectation of total recovery from the cataract condition by means of surgery was declared by 80.0% of the respondents, with no significant differences between male and female subjects (P < 0.1723). Hope to resume manual activities was expressed by 59.8%. CONCLUSION: A predominance of expectations of resuming normal activity and achieving a better quality of life after cataract surgery were identified.

Tissue expander complications in plastic surgery: a 10-year experience

INTRODUCTION: Tissue expanders have been of great value in plastic surgery. Tissue expansion was developed for a specific indication; however, within a very short time, the concept of tissue expansion found wide applicability. From 1990 to 1999, 315 expanders in 164 patients were utilized. A retrospective analysis of complications and prognostic factors for complications were done. METHODS: The indications for tissue expansion were burns (50%), trauma (32%), and sequelae of previous surgery (8.8%). The expanders were inserted most frequently in the scalp, trunk and neck. RESULTS: There were 22.2% of complications and the most common were expander exposure (50%), infection (24%) and bad function of the expander (12.8%). The present study revealed an increased rate of minor complications in the group of 0 to 10 years of age and an increased rate of major complications for face and neck expansions compared to trunk expansion. There were no increased complication rates for the other age and anatomic site groups, previous expansion, concomitant expansion and type of expander used. CONCLUSIONS: The outcomes from tissue expansion procedures done in our hospital are similar to those reported in the literature. Tissue expansion is a good and safe technique.

An experimental model for the transplantation of fetal central nervous system cells to the injured spinal cord in rats

INTRODUCTION: Traumatic spinal cord injury is one of the most disabling conditions occurring in man and thus stimulates a strong interest in its histopathological, biochemical, and functional changes, primarily as we search for preventive and therapeutic methods. PURPOSE: To develop an experimental model for transplantation of cells from the fetal rat central nervous system to the site of an injured spinal cord of an adult rat in which the transplanted cells survive and become integrated. This experimental model will facilitate investigations of factors that promote regeneration and functional recovery after spinal cord trauma. MATERIAL AND METHODS: Fifteen adult Wistar rats underwent laminectomy, and an spinal cord lesion was made with microdissection. Fetal spinal cord tissue was then transplanted to the site of the injury. The rats were monitored over a 48-hour period, and then their vertebral column was completely removed for histological analysis. RESULTS: In 60% of transplanted rats, the fetal tissue at the injured site remained viable in the site of the lesion.

Prostate innervation and local anesthesia in prostate procedures

The nerve supply of the human prostate is very abundant, and knowledge of the anatomy contributes to successful administration of local anesthesia. However, the exact anatomy of extrinsic neuronal cell bodies of the autonomic and sensory innervation of the prostate is not clear, except in other animals. Branches of pelvic ganglia composed of pelvic (parasympathetic) and hypogastric (sympathetic) nerves innervate the prostate. The autonomic nervous system plays an important role in the growth, maturation, and secretory function of this gland. Prostate procedures under local anesthesia, such as transurethral prostatic resections or transrectal ultrasound-guided prostatic biopsy, are safe, simple, and effective. Local anesthesia can be feasible for many special conditions including uncomplicated prostate surgery and may be particularly useful for the high-risk group of patients for whom inhalation or spinal anesthesia is inadvisable.

Surgery information reduces anxiety in the pre-operative period

PURPOSE: Patients preparing to undergo surgery should not suffer needless anxiety. This study aimed to evaluate anxiety levels on the day before surgery as related to the information known by the patient regarding the diagnosis, surgical procedure, or anesthesia. METHOD: Patients reported their knowledge of diagnosis, surgery, and anesthesia. The Spielberger State-Trait Anxiety Inventory (STAI) was used to measure patient anxiety levels. RESULTS: One hundred and forty-nine patients were selected, and 82 females and 38 males were interviewed. Twenty-nine patients were excluded due to illiteracy. The state-anxiety levels were alike for males and females (36.10 ± 11.94 vs. 37.61 ± 8.76) (mean ± SD). Trait-anxiety levels were higher for women (42.55 ± 10.39 vs. 38.08 ± 12.25, P = 0.041). Patient education level did not influence the state-anxiety level but was inversely related to the trait-anxiety level. Knowledge of the diagnosis was clear for 91.7% of patients, of the surgery for 75.0%, and of anesthesia for 37.5%. Unfamiliarity with the surgical procedure raised state-anxiety levels (P = 0.021). A lower state-anxiety level was found among patients who did not know the diagnosis but knew about the surgery (P = 0.038). CONCLUSIONS: Increased knowledge of patients regarding the surgery they are about to undergo may reduce their state-anxiety levels.
