No increased mortality from donor or recipient hepatitis B- and/or hepatitis C-positive serostatus after related-donor allogeneic hematopoietic cell transplantation.

Limited data exist on allogeneic transplant outcomes in recipients receiving hematopoietic cells from donors with prior or current hepatitis B (HBV) or C virus (HCV) infection (seropositive donors), or for recipients with prior or current HBV or HCV infection (seropositive recipients). Transplant outcomes are reported for 416 recipients from 121 centers, who received a human leukocyte antigen-identical related-donor allogeneic transplant for hematologic malignancies between 1995 and 2003. Of these, 33 seronegative recipients received grafts from seropositive donors and 128 recipients were seropositive. The remaining 256 patients served as controls. With comparable median follow-up (cases, 5.9 years; controls, 6.7 years), the incidence of treatment-related mortality, survival, graft-versus-host disease, and hepatic toxicity, appears similar in all cohorts. The frequencies of hepatic toxicities as well as causes of death between cases and controls were similar. Prior exposure to HBV or HCV in either the donor or the recipient should not be considered an absolute contraindication to transplant.

Diagnostic Accuracy of MRI for Detection of Meningitis in Infants.

PURPOSE: To determine the accuracy of MR imaging for diagnosis of meningitis in infants. MATERIALS AND METHODS: Retrospective review of infants less than 1 year of age who underwent a brain MR imaging for meningitis from 2010-2018. Gold standard for diagnosis of bacterial meningitis was a positive bacterial CSF culture or a positive blood culture with an elevated CSF WBC count, and diagnosis of viral meningitis was a positive CSF PCR result and elevated CSF WBC count. Sensitivity, specificity, PPV, NPV, and accuracy for MR imaging diagnosis of meningitis were calculated. RESULTS: Two hundred nine infants with mean age 80 days (range 0-347 days) were included. There were 178 true positives with the most common pathogens being: Group B Streptococcus (58), E. coli (50), Streptococcus pneumoniae (21), H. influenzae (4); Herpes simplex virus 1 or 2 (18); Enterovirus (4); and other (23). There were 31 true negatives. Range of sensitivity, specificity, PPV, NPV, and accuracy of MR imaging for detection of meningitis was 67.4-83.5%, 92.3-95.7%, 95.0-98.6%, 33.3-76.5%, and 71.3-86.5% respectively. MR imaging sensitivity decreased after 10 days from time of presentation while specificity remained stable. Among individual MR imaging findings, leptomeningeal enhancement was the most sensitive finding, while cerebritis, infarction, ventriculitis, abscess, and intraventricular purulent material were the most specific findings. CONCLUSIONS: MR imaging of the brain demonstrates high specificity and moderate sensitivity for diagnosis among infants presenting with signs and symptoms of meningitis. The results reflect current standard of care for imaging of infants with meningitis however a selection bias for imaging of more severe meningitis may affect these results.

Accuracy of MR Imaging for Detection of Sensorineural Hearing Loss in Infants with Bacterial Meningitis.

BACKGROUND AND PURPOSE: Bacterial meningitis most commonly affects young children and can result in critical adverse outcomes, including sensorineural hearing loss (SNHL). The purpose of this study is to determine the diagnostic accuracy of MR imaging for predicting the development of SNHL among infants with bacterial meningitis. MATERIALS AND METHODS: A retrospective review was performed among infants (age <365 days) with bacterial meningitis (n = 115). Independent and consensus blinded review of brain MRIs (n = 239) performed less than 90 days from presentation were conducted. Abnormal appearance of the inner ear was defined as enhancement on postcontrast T1-weighted (T1-weighted+C) sequence and FLAIR hyperintensity. The consensus MR imaging appearance of the inner ear on FLAIR, T1-weighted+C, and combined evaluation was compared with criterion standard audiometric testing to determine the sensitivity and specificity of MR imaging for detecting SNHL. RESULTS: The mean age at diagnosis of bacterial meningitis was 50.6 days (range, 0-338 days) and 24.3% had SNHL. Sensitivity and specificity was 0.61/0.96, 0.50/0.94, and 0.61/0.94 for T1-weighted+C, FLAIR hyperintensity, and combined evaluation, respectively, for prediction of SNHL. There was excellent interobserver agreement for both the T1-weighted+C and FLAIR sequences and combined evaluation for presence of abnormal enhancement and hyperintense signal, respectively. Factors associated with abnormal MR imaging findings on T1-weighted+C and/or FLAIR in patients with SNHL included low CSF glucose (P = .04, .02) and high CSF protein (P = .04, .03). CONCLUSIONS: Abnormal enhancement and/or FLAIR hyperintensity of the inner ear demonstrate high specificity and average sensitivity for prediction of SNHL among infants with bacterial meningitis.

Comparison of CSF and MRI Findings among Neonates and Infants with E coli or Group B Streptococcal Meningitis.

BACKGROUND AND PURPOSE: Group B Streptococcus and Escherichia coli (E coli) are the 2 most common causes of bacterial meningitis in neonates. The purpose of this study was to determine whether CSF and/or MR imaging findings differ between infants with group B streptococcal or E coli meningitis. MATERIALS AND METHODS: A retrospective review was performed among neonates (younger than 28 days) and infants (younger than 120 days) with proved group B streptococcal (n = 57) or E coli meningitis (n = 50). A CSF or blood culture positive for Streptococcus or E coli and an elevated CSF white blood cell count were used as the criterion standard. Independent, blinded review of brain MRIs obtained within 21 days of presentation were performed by 2 board-certified neuroradiologists. CSF laboratory values and MR imaging findings were compared between the groups. RESULTS: There was no statistically significant difference between the mean age at presentation for patients with group B streptococcal (40 days; range, 2-111 days) versus patients with E coli meningitis (31 days; range, 12-115 days) (P = .18). There was no statistically significant difference in the CSF white blood cell count, glucose, or protein. There was a significant difference between group B streptococcal and E coli meningitis in the frequency of hydrocephalus (0% versus 22%, P = .001) and infarct (40% versus 14%; P = .038), respectively. There was no statistically significant difference in leptomeningeal enhancement, cerebritis, ventriculitis, abscess/granuloma, subdural effusion, extra-axial purulent material, intraventricular purulent material, hemorrhage, and sinus thrombosis. CONCLUSIONS: Although neonates and infants with group B streptococcal or E coli meningitis had similar age and CSF laboratory values, patients with group B streptococcal meningitis more frequently demonstrated infarcts, while those with E coli meningitis more frequently had early onset of hydrocephalus.

Genital tuberculosis in Indian infertility patients.

OBJECTIVES: To analyze the clinical and laparoscopic features of 40 infertile women with genital tuberculosis. MATERIALS AND METHODS: This prospective clinical study was carried out at a tertiary care hospital from October 1, 2004, to August 30, 2006, with 150 infertile women in whom there was clinical suspicion of genital tuberculosis. All underwent diagnostic laparoscopy and biopsy for confirmation and other causes of infertility were excluded. RESULTS: Among the 40 infertile women affected with genital tuberculosis there were cases of primary (n=30) and secondary (n=10) infertility; pelvic pain (n=8); menorrhagia (n=9); oligomenorrhea (n=7); hypomenorrhea (n=8); and primary (n=2) and secondary (n=2) amenorrhea. There were histories of pulmonary (n=9) and abdominal tuberculosis (n=6), ectopic pregnancy (n=4), and antitubercular treatment (n=10) in 10. There were cases of positive Mantoux test results (n=2); endometrial aspiration showing tubercular endometritis (n=10); positive acid-fast bacillus culture results (n=1); and positive polymerase chain reaction results (n=9). Laparoscopic examination revealed abnormally dilated, tortuous, and blocked fallopian tubes (n=13); peritubal and periovarian adhesions (n=18); Fitz Hugh Curtis syndrome (n=15); omental adhesions (n=18); and bowel adhesions (n=15). Hysteroscopy revealed flimsy intrauterine adhesions (n=7). All patients were treated for tuberculosis and 13 were counseled for in-vitro fertilization and embryo transfer or adoption. CONCLUSION: Genital tuberculosis is common in India and a combination of clinical and laparoscopic diagnoses, along with endometrial histopathologic studies, acid-fast bacillus culture, and polymerase chain reaction assays provides the best available method for the diagnosis of genital tuberculosis in infertile women.

Surveillance for West Nile virus cases in Louisiana 2001-2004.

West Nile virus (WNV) was first detected in Louisiana during August of 2001. An outbreak of 204 human cases of neuro-invasive disease (NID) and 25 deaths occurred in 2002. In the 2 years following, lower numbers of human cases were identified (101 NID cases in 2003 and 84 in 2004) but intense localized foci were observed. The incidence of NID has been particularly high in the elderly (65 years and older). The distribution of West Nile cases has consisted of sporadic cases with a few very intense foci. Annually, human cases have occurred from June through December, with a peak number of new cases in August. As compared with other WNV serosurveys conducted in the United States, it appears that the WNV seroprevalence in Louisiana is not elevated.

Prognostic factors for outcomes in allogeneic transplantation for CML in the imatinib era: a CIBMTR analysis.

Allogeneic hematopoietic SCT is an effective treatment in accelerated (AP) or blast phase (BP) CML. Imatinib (IM) has transient but significant activity in advanced phases of CML, which may permit early allografting for responding patients. To identify prognostic factors in allograft recipients previously treated with IM, we analyzed 449 allogeneic hematopoietic SCTs performed from 1999 to 2004 in advanced-phase CML, using the data reported to the Center for International Blood and Marrow Transplant Research. CML patients in second chronic phase (CP2, n=184), AP (n=185) and BP (n=80) received HLA-identical sibling (27%), related (3%), or matched or mismatched unrelated donor (70%), peripheral blood (47%) or BM (53%) hematopoietic SCT after myeloablative (78%) or non-myeloablative (22%) conditioning. In all, 52% in CP2, 49% in AP and 46% in BP received IM before hematopoietic SCT. Disease-free survival was 35-40% for CP2, 26-27% for AP and 8-11% for BP. Cumulative incidence of acute and chronic GVHD and TRM were not affected by the stages of CML or pre-hematopoietic SCT IM exposure. Multivariate analyses showed that conventional prognostic indicators remain the strongest determinants of transplant outcomes. In conclusion, there are no new prognostic indicators of the outcomes of allogeneic hematopoietic SCT for advanced-phase CML in the IM era.

Verruciform xanthoma of the penis in a young male masquerading as squamous cell carcinoma: case report.

Verruciform xanthoma (VX) is a relatively rare benign lesion of unknown etiology with a predilection for oral mucosa. Penis is an uncommon location and to date only 17 cases of VX of penis have been reported. The lesion assumes importance as it can be easily mistaken for verrucous carcinoma or squamous cell carcinoma. We present herein a case of penile VX in a 25-year-old man who was referred to our institute with a histopathologic diagnosis of squamous cell carcinoma reported elsewhere. On microscopy the lesion demonstrated florid verruciform hyperplasia of the epidermis with hyperkeratosis, parakeratosis and acanthosis. There was a dense infiltrate of foam cells in the papillary dermis (a hallmark of VX), which were positive for CD68 and negative for S-100 protein. We present this case to highlight the significance of recognizing VX in extra oral location. An awareness of this entity is crucial to prevent misdiagnosis and halt inappropriate therapeutic intervention.

Anaplastic variant of clear cell sarcoma of the kidney: a rare case report.

Clear cell sarcoma (CCSK) of the kidney is an uncommon but distinctive pediatric renal tumor with a characteristic histological pattern and marked propensity for bone metastasis. The rare anaplastic variant constitutes about 3% of cases of CCSK and carries an unfavorable prognosis, with increased tumor recurrence and resistant to chemotherapy. This variant show high frequency of p53 gene mutation and p53 over expression in comparison to the usual CCSK. We present a case of anaplastic variant of CCSK in an 10-year-old boy with both cytologic and histologic features, highlighting the importance of recognizing this rare entity.

Long-term clinical remission following radiotherapy in tracheal adenocarcinoma: review of the published work.

A 55-year-old man with tracheal adenocarcinoma presented with difficulty in breathing and cough with blood-tinged expectoration. As the patient refused surgery, he was treated with definitive radiotherapy to the neck and superior mediastinum to a total dose of 50 Gy (initially 40 Gy by AP/PA portals followed by 10 Gy with a three-field technique). He showed significant symptomatic relief to radiotherapy and defaulted from further treatment. He remained asymptomatic for 7 years, following which he developed sternal metastases and a local tumour recurrence. This case illustrates that long-term clinical remission can be achieved by radiotherapy alone in this rare histological subtype of tracheal carcinoma.
