BACKGROUND: Histoplasmosis (HP) is diagnosed by visualizing intracellular microorganisms in biopsy and/or culture. Periodic-acid Schiff (PAS) and Gomori methenamine silver (GMS) staining methods are routinely used for identification. The acid-fast property of Histoplasma was identified decades ago, but acid-fast staining has not been practiced in current surgical pathology. Awareness of the acid-fast property of Histoplasma, which is due to mycolic acid in the cell wall, is important in distinguishing Histoplasma from other infective microorganisms. Here, we examined acid-fastness in previously diagnosed cases of Histoplasma using the Ziehl-Neelsen (ZN) stain and correlated those findings with other known fungal stains. METHODS: All cases diagnosed as HP were retrieved and reviewed along with ZN staining and other fungal stains. We also stained cases diagnosed with Cryptococcus and Leishmania as controls for comparison. RESULTS: A total of 54 patients ranging in age from 11 to 69 years were examined. The most common sites of infection were the skin, adrenal tissue, and respiratory tract. Of the total 43 tissue samples, 20 (46.5%) stained positive with the ZN stain. In viable cases, a significant proportion of microorganisms were positive while necrotic cases showed only rare ZN-positive yeasts. In comparison to PAS and GMS stains, there was a low burden of ZN-positive yeasts. Cryptococcus showed characteristic ZN staining and all cases of Leishmania were negative. CONCLUSIONS: Although the morphology of fungal organisms is the foundation of identification, surgical pathologists should be aware of the acid-fast property of fungi, particularly when there is the potential for confusion with other infective organisms.

PURPOSE: Urodynamic studies are commonly performed as part of the preoperative work-up of patients undergoing surgery for stress urinary incontinence (SUI). We aimed to assess the extent to which these urodynamic parameters influence patient selection and postoperative outcomes. MATERIALS AND METHODS: Patients presenting with SUI were randomly assigned to two groups: one undergoing office evaluation only and the other with a preoperative urodynamic work-up. Patients with unfavorable urodynamic parameters (detrusor overactivity [DO] and/or Valsalva leak point pressure [VLPP]<60 cm H2O and/or maximum urethral closure pressure [MUCP]<20 cm H2O) were excluded from the urodynamic testing group. All patients in both groups underwent the transobturator midurethral sling procedure. Evaluation for treatment success (reductions in urogenital distress inventory and incontinence impact questionnaire scoring along with absent positive stress test) was done at 6 months and 1 year postoperatively. RESULTS: A total of 72 patients were evaluated. After 12 patients with any one or more of the abnormal urodynamic parameters were excluded, 30 patients were finally recruited in each of the "urodynamic testing" and "office evaluation only" groups. At both the 6- and the 12-month follow-ups, treatment outcomes (reduction in scores and positive provocative stress test) were significantly better in the urodynamic testing group than in the office evaluation only group (p-values significant for all outcomes). CONCLUSIONS: Our findings showed statistically significantly better treatment outcomes in the urodynamic group (after excluding those with poor prognostic indicators such as DO, low VLPP, and MUCP) than in the office evaluation only group. We recommend exploiting the prognostic value of these urodynamic parameters for patient counseling and treatment decisions.

An 18-year-old Indian boy presented with increasing weight, generalised weakness, proximal myopathy and some rashes over his abdomen for the last 6 months. On examination, he was found to have broad purple striae on his abdomen, hypertension and proximal myopathy. He gave history of exogenous oral steroid use for his bronchial asthma which had been more frequent for the last year.

A 16-year-old Indian girl presented with increased facial hair growth, weight gain, amenorrhea and generalized weakness for the last 3 months. On examination she was found to have severe hirsutism, her modified Ferriman-Gallwey score was 24/36, she had broad purple striae on abdomen, hypertension and proximal myopathy. On investigations, the patient was found to have ACTH dependent Cushing's syndrome
