Intracranial hypotension (IH), often resulting from a cerebrospinal fluid (CSF) leak, is a notable cause of secondary headaches. Diagnosing IH through clinical assessment and neuroimaging can be challenging. Orthostatic headache (OH), characterized by neck stiffness, nausea, dizziness, phonophobia, and photophobia, is a key symptom of CSF leakage, which may stem from a variety of causes, including falling, surgery, CSF studies, or arachnoid diverticula. This study presents two OH patients with IH who were incidentally found to have an underlying meningocele.

Organizing hematomas are rare benign tumors and appear as forms of mass which is composed of neovascularization with organizing fibrous tissue in hematoma. There have been sporadic reports of the organizing hematoma not only in soft tissue but also in brain, spinal cord, lung, and maxillary sinus. We report a case of organizing hematoma that was restricted in the nasal cavity without inclusion of the paranasal sinus. This is the first article describing the organizing hematoma of the nasal septum. We present this case with a review of literature.

BACKGROUND: The value of plasma concentration of 8-Methoxypsoralen(8-MOP) in the supervision of photochemotherapy has been recognized. However, plasma levels of 8-MOP were not proportionate to the degree of PUVA induced erythema and couldn't alone predict the degree of PUVA induced erythemal reaction. We made a speculation that the degree of PUVA induced erythema might correlate better with skin tissue levels of 8-MOP than plasma levels. Suction blister fluid(SBF) has been known to represent tissue fluid in the skin. So we per-formed a study of comparison of 8-MOP concentrations in both plasma and SBF. OBJECTIVE: Our purpose was to evaluate the correlation of the concentrations of 8-MOP in plasma and SBF 2 hours after oral administration of 0.6 mg/kg of 8-MOP. METHODS: Twenty six patients, aged between 16 and 50 years, undergoing suction blister surgery for vitiligo treatment, participated in this open study. Single oral doses of 0.6 mg/kg of body weight of 8-MOP were taken. Blood samples(5ml) and SBF(2ml) were collected at 2 hours after the drug administration, and 8-MOP concentration in plasma and SBF were quantitated by reverse phase high-performance liquid chromatography (HPLC). RESULTS: 8-MOP concentrations in plasma and SBF ranged from 18 to 545 ng/ml and 8 to 179 ng/ml, respectively. On the analysis of linear regression, a close-relation could not be observed between two SBF levels; measured and predicted values which were calculated from measured plasma and SBF concentrations (r²=0.583, P < 0.001). CONCLUSION: The correlation of plasma and SBF concentrations of 8-MOP is weak. So, SBF levels of psoralen are recommended for the study of PUVA erythemal reactions.

BACKGROUND: Human papillomavirus (HPV) is a major risk factor for cervical cancer. METHODS: We evaluated the clinical significance of the HPV DNA chip genotyping assay (MyHPV chip, Mygene Co.) compared with the Hybrid Capture 2 (HC2) chemiluminescent nucleic acid hybridization kit (Digene Corp.) in 867 patients. RESULTS: The concordance rate between the MyHPV chip and HC2 was 79.4% (kappa coefficient, κ = 0.55). The sensitivity and specificity of both HPV tests were very similar (approximately 85% and 50%, respectively). The addition of HPV result (either MyHPV chip or HC2) to cytology improved the sensitivity (95%, each) but reduced the specificity (approximately 30%, each) compared with the HPV test or cytology alone. Based on the MyHPV chip results, the odds ratio (OR) for ≥ high-grade squamous intraepithelial lesions (HSILs) was 9.9 in the HPV-16/18 (+) group and 3.7 in the non-16/18 high-risk (HR)-HPV (+) group. Based on the HC2 results, the OR for ≥ HSILs was 5.9 in the HR-HPV (+) group. When considering only patients with cytological diagnoses of “negative for intraepithelial lesion or malignancy” and “atypical squamous cell or atypical glandular cell,” based on the MyHPV chip results, the ORs for ≥ HSILs were 6.8 and 11.7, respectively, in the HPV-16/18 (+) group. CONCLUSIONS: The sensitivity and specificity of the MyHPV chip test are similar to the HC2. Detecting HPV-16/18 with an HPV DNA chip test, which is commonly used in many Asian countries, is useful in assessing the risk of high-grade cervical lesions.

BACKGROUND: Procalcitonin (PCT) is a relatively new marker for bacterial infections, and its diagnostic utility has been variable across the studies. We investigated the diagnostic utility of PCT for the patients with blood culture-positive sepsis, and compared it with that of C-reactive protein (CRP). METHODS: In 1,270 consecutive blood samples, PCT and CRP were simultaneously measured and results were compared according to the five categories of PCT concentrations (<0.05 ng/mL; 0.05-0.49 ng/mL; 0.5-1.99 ng/mL; 2-9.99 ng/mL; > or =10 ng/mL). In 506 samples, they were further analyzed according to the result of blood culture. PCT and CRP were measured using enzyme-linked fluorescent assay (bioMerieux Co., France) and rate nephelometry (Beckman Coulter Co., USA), respectively. Their diagnostic utilities were compared using ROC curves. RESULTS: The mean concentrations of CRP in five categories of PCT were 15.4 mg/L, 42.1 mg/L, 101.2 mg/L, 125.0 mg/L, 167.1 mg/L, respectively (P<0.0001). Both PCT and CRP showed significant differences between the two positive and negative groups of blood culture (PCT, 8.47 vs 2.44 ng/mL, P=0.0133; CRP, 110.48 vs 59.78 mg/L, P<0.0001). The areas under the ROC curves (95% confidence interval) for PCT and CRP were 0.720 (0.644-0.788) and 0.558 (0.478-0.636), respectively, and showed a significant difference (P=0.005). CONCLUSIONS: The diagnostic utility of PCT is superior to that of CRP for the patients with blood culture-positive sepsis. PCT seems to be reliable for sepsis diagnosis, and may provide useful information for the critically ill patients.

Cystic dysplasia of the rete testis (CDT) is a very rare congenital benign testicular tumor that is often associated with ipsilateral genitourinary anomalies. It is usually found in the pediatric population and must be differentially diagnosed from a malignant lesion. Here we report the case of a 63-year-old man with a left inguinal hernia who visited our urologic outpatient clinic. Scrotal ultrasonography showed a left direct inguinal hernia in the inguinal area and a well-circumscribed cystic lesion containing multiple minute cysts with echogenic foci occupying almost one-third of the left testicular parenchyma. Testicular tumor markers were within the normal range and a computed tomography scan of the abdomen showed no genitourinary abnormalities. We presumed that the left testicular lesion was malignant, and the patient underwent radical orchiectomy. However, the pathologic examination revealed a CDT. Here we present this case of a 63-year-old man with an inguinal hernia accompanied by multiple cystic lesions on the left testis.

PURPOSE: The aim of this study was to evaluate the efficacy of periprostatic lidocaine injection according to lidocaine dose during transrectal ultrasound-guided prostate biopsy. MATERIALS AND METHODS: The subjects of this study were 92 patients who had undergone transrectal ultrasound-guided 12-core biopsy of the prostate. The patients were randomly assigned to three groups: group 1 (n=31, no lidocaine injection), group 2 (n=30, periprostatic injection of 10 ml 1% lidocaine), and group 3 (n=31, periprostatic injection of 20 ml 1% lidocaine). The patients were assessed for pain by use of a 10-point visual analogue scale (VAS) and for other complications after the procedure. RESULTS: The mean VAS scores of groups 1 through 3 were 0.93+/-0.89, 1.32+/-1.37, and 1.13+/-1.10, respectively. There were no statistically significant differences between the three groups. However, the mean VAS score of the biopsy pain was 5.0+/-1.48, 3.93+/-1.94, and 3.60+/-2.15, in the same groups, respectively, with statistically significant differences between group 1 and the other groups. Patients in groups 2 and 3 reported significantly less biopsy pain than did group 1 patients (p=0.004, 0.021), with no statistically significant difference in VAS score between groups 2 and 3 (p=0.533). With respect to post-biopsy complications, there were no significant differences in the incidence of hematuria, hematospermia, rectal bleeding, or infection among the three groups. CONCLUSIONS: Periprostatic injection of local anesthesia with lidocaine was associated with significantly less pain than in the absence of anesthesia. Furthermore, a 20-ml dose of lidocaine produced no better pain control than did a 10-ml lidocaine dose for prostate biopsy.
