This is a report of 7 cases of mucormycosis infections in patients who had undergone transplantation and been admitted in the kidney transplant centre of Baqiyatallah Hospital in Tehran, Iran, from 2002 to 2005. We retrospectively reviewed the hospital records for demographic data, symptoms, diagnostic techniques and outcomes. Five patients were male and 2 female. The mean age of patients was 49.5 y. The time interval between transplantation and disease onset varied greatly (range: 1 month to 4 y). Patients' symptoms were fever (7 cases), respiratory distress (4 cases) and severe headache (3 cases). Suspected patients were evaluated by CT scan, BAL and biopsy and diagnosis confirmed by culture. The final diagnosis was pulmonary mucormycosis in 4 cases, rhino-cerebral mucormycosis in 2 cases and disseminated mucormycosis in 1 case. Despite early and intensive treatment with amphotericin B in all patients and extensive debridement in 3 cases, only 2 patients survived the disease. Mucormycosis is a potentially lethal complication after kidney transplantation. It could occur very early on or very late into the post-transplant period. Despite the results of other studies, the most frequent site of infection in our patients was the lungs.
Background: Despite the popularity of kidney transplantation in the current era, second and third kidney transplantation are not yet widely accepted and practiced. Each center has its own regulations and experiences and there is no accepted protocol for third kidney transplantation. We report here our 15 years of experience with third kidney transplantation. Methods: This is a report of all the third kidney transplantations performed in Baqiyatallah Hospital, Tehran, Iran, between 1991 and 2006. Demographic data, surgical techniques, complications and outcomes are reported. Results: Of the nine third kidney transplant patients, six were male. The median age was 43 years (32-52). All of the patients received kidney from living donors. All operations were performed by a midline incision and the grafts were placed at the midline, in the intraperitoneal space. For arterial anastomosis, we used internal iliac, right common iliac and both the right external iliac and inferior mesenteric artery in 4, 4 and 1 case(s), respectively. For venous anastomosis, we used vena cava, common iliac and external iliac veins in 3, 5 and 1 case(s), respectively. During the follow up period (38 months), 6 grafts (66.6%) were functioning. None of the graft rejections were due to surgical complications. Wound dehiscence occurred in two patients. No other surgical complications including infection, lymphocele or hemorrhage were observed. Conclusion: Third kidney transplantation is a field that has not been fully explored. The rate of complications seems to be not much higher than the first transplantation. Defining a standard protocol seems necessary.
OBJECTIVE The purpose of this prospective study was to evaluate the dysfunction of the nervus intermedius (NI) after vestibular schwannoma (VS) surgery. The authors present a clinically feasible method for this purpose. METHODS In this prospective study, the authors included 30 patients who underwent surgery at the International Neuroscience Institute between May 2014 and February 2017 for resection of VS. The patients' taste sensation was examined using taste strips. Lacrimation was tested using the Schirmer I test. The clinical evaluation was performed before surgery and repeated at 2 weeks and at 6 months after surgery as well as during the follow-up, which extended up to 2 years. The authors tested the correlation between the NI dysfunctions and the House-Brackmann grade of facial nerve palsy. RESULTS The taste sensation was lost on the side of surgery in 2 patients (6.6%) and decreased in 4 patients (13.3%). The disturbance of taste sensation was not statistically correlated with dysfunctions of the motor portion of the facial nerve. The taste impairment resolved in 4 patients within 6 months, but 2 patients suffered from persistent loss of the taste sensation on the side of surgery during the follow-up. In 23 patients (76.6%), the baseline lacrimation was lower on the side of surgery, and it was significantly correlated with outcome for dysfunctions of the motor portion of the facial nerve. During the follow-up, baseline lacrimation improved in correlation with the improvement in the dysfunctions of the motor portion of the facial nerve. None of the patients reported change in salivation or nasal secretion. CONCLUSIONS The NI can be affected after VS surgery. The disturbance of baseline lacrimal secretion was correlated with dysfunctions of the motor portion of the facial nerve. However, the disturbance of the taste sensation was not correlated with the grade of facial nerve palsy. Dysfunctions of the NI should be evaluated and separately reported while analyzing facial nerve outcome after VS surgery.
