Correlation Between Serum Tumor Marker Levels and Connective Tissue Disease-Related Interstitial Lung Disease.

OBJECTIVE: The main aims of this study were to explore the relationships between serum tumor markers and connective tissue disease-related interstitial lung disease (CTD-ILD) and to evaluate the clinical value of tumor markers for investigating interstitial lung disease (ILD) in patients with connective tissue disease (CTD). METHODS: The study included 235 patients with CTD (90 CTD without ILDs, 145 CTD-ILD). Clinical information and the levels of inflammatory and tumor markers, including carbohydrate antigen (CA) 19-9, CA125, carcinoembryonic antigen (CEA), CA153, and cytokeratin 19 fragments (CYFRA21-1), were obtained in all the patients. RESULTS: A significant difference between CTD with or without ILD and higher levels of tumor markers was observed in the CTD-ILD group, including CA19-9 (p<0.001), CEA (p<0.001), CA153 (p<0.001), and CYFRA21-1 (p<0.001). There was no significant difference in serum tumor marker levels in the various types of CTD (rheumatoid arthritis, systemic lupus erythematosus, Sjogren's syndrome, inflammatory myositis, systemic sclerosis, and mixed connective tissue disease). The levels of CA153 [odds ratio (OR)=1.159] and CYFRA21-1 (OR=2.269) were clearly related to the risk of CTD-ILD. The diagnostic value of CA153 [area under receiver operating characteristic curve (AUC)=0.736] and CYFRA21-1 (AUC=0.718) was confirmed for ILDs in CTD patients, at cut-off values of 9.45 U/mL and 2.13 ng/mL, respectively. CONCLUSION: There is a positive correlation between serum tumor marker levels and CTD-ILD. Higher levels of CA153 and CYFRA21-1 suggest an increased risk of developing ILD and may therefore be useful as biomarkers for detecting CTD-ILD in the clinical setting.

Study on Hair Distribution in Healthy Males for Hair Restoration Design.

BACKGROUND: The incidence of hair loss among Chinese male has increased to 21.3 per hundred. Hair restoration has been an effective technique. Detailed hair distribution has a tremendous impact on the surgery design. OBJECTIVE: To investigate the pattern of hair distribution in Chinese young adult males. METHODS: A total of 1000 males without hair disease were enrolled. We evaluated the locations of the main anatomical marks at different sites on the scalp and analyzed the hair density and follicular unit structure using the standard photographs and trichoscope. RESULTS: The hairline shapes were classified as: linear (48.7%), linear with central protrusion (27.9%), round (9.8%), round with central protrusion (13.7%). The average height of the median line was 6.78 ±â€Š0.75 cm, the ratio of the median line and the forehead height was 0.333. The average distance from the parietal whorl to the vertical bimeatal line was 7.05 ±â€Š3.32 cm, and most of the PWs were on the right (51.4%) and had a clockwise pattern (73.3%). The hair density was 171.12 ±â€Š18.32 hairs/cm in the vertex. 1-hair follicular units were (75.90% and 56.39%) in anterior hairline and temporal area. CONCLUSION: Our study clearly assisted understanding of scalp anatomy and hair distribution in Chinese young adult males.

Cutaneous mucormycosis caused by Rhizopus microsporus in an immunocompetent patient: A case report and review of literature.

RATIONALE: Cutaneous mucormycosis is an uncommon disease and occurs rarely in immunocompetent patients. PATIENT CONCERNS: We reported the case of a 37-year-old man presenting with a skin lesion on the left side of the chest wall with no history of trauma or primary diseases. He was firstly misdiagnosed as tuberculosis and the proper treatment was thus delayed. DIAGNOSES: Histopathological examination and fungal culture of the lesion confirmed cutaneous mucormycosis. The isolate was identified as Rhizopus microspores by ITS sequencing. INTERVENTIONS: The patient was treated with oral posaconazole 400 mg bid for 150 days. OUTCOMES: The patient recovered satisfactorily. No recurrence was found during the follow-up and no side effect of liver function was found. LESSONS: This case helps doctors to consider the possibility of serious fungal infection in immunocompetent patients. It also suggested that posaconazole could be an alternative choice for the treatment of mucormycosis considering the severe side effect of Amphotericin B.
