Objective: To detect the presence of lymphatic vessels in the cornea through histopathological examination, trying to identify findings that are most commonly found with the presence of these vessels in this tissue. Methods: Retrospective descriptive study of human corneal buttons with lymphangiogenesis. Tissues were obtained from penetrating keratoplasty in the period between the years 2006 and 2013. A medical record review was conducted looking for information about sex, age and graft etiology. Results: 89 corneal buttons were included, out of which 37 were from female patients and 52 were from male patients. The average age was 47.70 ± 23.95 years (mean ± SD). Lymphangiogenesis was found mainly associated with hemangiogenesis. However, isolated lymphangiogenesis was observed in 28 (31.46%) patients. In 18 (20.22%) cases were found an amount of lymphatic vessels approximately four times higher than that found in most part of the sample. A lot of cases were found in inflammatory conditions such as infection and perforation. Near the lymphangiogenesis, we found many cases of anterior synechia and myofibroblasts. In 17 (16.35%) cases, no change was observed in the vicinity of corneal lymphatic vessels. Conclusion: We demonstrated through a histopathological examination, that findings admittedly associated with lymphangiogenesis like inflamamatory processes, are also frequently found in cases of human corneas that have lymphatic vessels. However, other findings such as lymphangiogenesis without the presence of angiogenesis, the presence of a greater amount of vessels in some cases and lymphangiogenesis without changes in its proximity remain in need of a better understanding.

Object. Acromegaly is a chronic disease related to the excess of growth hormone (GH) and insulin-like growth factor-I secretion, usually by pituitary adenomas. Traditional treatment of acromegaly consists of surgery, drug therapy, and eventually radiotherapy. The introduction of endoscopy as an additional tool for surgical treatment of pituitary adenomas and, therefore, acromegaly represents an important advance of pituitary surgery in the recent years. The aim of this retrospective study is to evaluate the results of pure transsphenoidal endoscopic surgery in a series of patients with acromegaly who were operated on by a pituitary specialist surgeon. The authors discuss the advantages, outcome, complications, and factors related to the success of the endoscopic approach in cases of GH-secreting adenomas. Methods. The authors retrospectively analyzed data from cases involving patients with GH-secreting adenomas who underwent pure transsphenoidal endoscopic surgery at the Department of Neurosurgery of the General Hospital in Fortaleza, Brazil, between 2000 and 2009. Tumors were classified according to size as micro- or macroadenomas, and tumor extension was analyzed based on suprasellar/parasellar extension and sella floor destruction. All patients were followed up for at least 1 year. The criteria of disease control were GH levels < 1 ng/L after oral glucose tolerance test and normal insulin-like growth factor-I levels for age and sex. Results. During the study period, 67 patients underwent pure endoscopic transsphenoidal surgery for treatment of acromegaly. Disease control was obtained in 50 cases (74.6%). The rate of treatment success was higher in patients with microadenomas (disease control achieved in 12 [85.7%] of 14 cases) than in those with larger lesions. Suprasellar/parasellar extension and high levels of sella floor erosion were associated with lower rates of disease control (p = 0.01 and p = 0.02, respectively). Complications related to the endoscopic surgery included epistaxis (6.0%), transitory diabetes insipidus (4.5%), and 1 case of seizure (1.5%).Conclusions. Endoscopic transsphenoidal surgery represents an effective option for treatment of patients with acromegaly. High disease control rates and a small number of complications are some of the most important points related to the technique. Factors related to the success of the endoscopic surgery are lesion size, suprasellar/parasellar extension, and the degree of sella floor erosion. Although presenting important advantages, there is no conclusive evidence that endoscopy is superior to microsurgery in treatment of GH-secreting adenomas.

Influenza A infection has been described as a major viral cause of infection-induced rhabdomyolysis, but to date, only one reported case was described as having been induced by influenza vaccine. We describe a case of a man who had been using statins and developed rhabdomyolysis the day after influenza A H1N1 vaccination. A 58-year-old man was admitted at the emergency room complaining of impaired gait. The patient reported receiving influenza A H1N1 vaccine 5 days prior to the admission, with symptoms beginning the day after the inoculation. He reported ascending weakness, intense myalgia in the lower back, upper and lower limbs. The admission laboratory tests showed serum creatine phosphokinase: 7600 IU/L, creatinine: 3.0 mg/dL, urea: 185 mg/dL, aspartate aminotransferase: 592 IU/L, alanine aminotransferase: 630 IU/L, potassium: 5.4 mEq/L, lactate dehydrogenase: 2828 IU/L. Despite intravenous fluid therapy, the patient still persisted with oliguria and urinary output of 0.17 ml/kg/h. Hemodialysis was initiated and renal function recovery was observed after two weeks. The patient was hemodynamically stable and asymptomatic at hospital discharge. This is a rare side effect of influenza A H1N1 vaccine. Physicians should advise patients to seek medical care when muscle symptoms are present and consider the possibility of rhabdomyolysis due to vaccination. Trials are required to better define the incidence of this important side effect. © 2013 Elsevier Ltd. All rights reserved.

Trichosporon spp. are yeasts capable of causing invasive disease, which mainly affect immunocompromised patients. A clinical strain of T. asahii was isolated from the blood cultures of patients admitted to the General Hospital of Fortaleza. Susceptibility tests were conducted by disk diffusion and broth microdilution. The isolated strain of T. asahii was resistant to fluconazole. The patient used amphotericin B and caspofungin in order to facilitate the microbiological cure. It was the first isolation and identification of T. asahii in blood culture in Ceará, Brazil.

OBJECTIVE:: To evaluate the influence of myofascial pain on the Pressure Pain Threshold (PPT) of masticatory muscles in women with migraine. METHODS:: The sample comprised 101 women, ages ranging from 18 to 60 years, with an episodic migraine diagnosis previously confirmed by a neurologist. All patients were evaluated using Research Diagnostic Criteria for Temporomandibular Disorders to determine the presence of myofascial pain and were divided into 2 groups: group I (n=56), comprising women with a migraine, and group II (n=45), comprising women with a migraine and myofascial pain. Two more groups (49 asymptomatic women and 50 women with myofascial pain), matched for sex and race, obtained from a previous study, were added to this study. The PPT values of masseter and temporalis (anterior, middle, and posterior regions) muscles were recorded bilaterally using a pressure algometer. One-way analysis of variance and the Tukey test for pairwise comparisons were used in statistical analysis with a 5% significance level. RESULTS:: We found that all groups had significantly lower PPT values compared with asymptomatic women, with lower values seen in group II (women with migraine and myofascial pain). Women with a migraine and myofascial pain showed significantly lower PPT values compared with women with a migraine only, and also when compared with women with myofascial pain only. DISCUSSION:: Migraine, especially when accompanied by myofascial pain, reduces the PPT of masticatory muscles, suggesting the importance of masticatory muscle palpation during examination of patients with migraine.
