Hepatic fibrosis is a scarring process associated with an increased and altered deposition of extracellular matrix in the liver. It is caused by a variety of stimuli and if fibrosis continues unopposed, it would progress to cirrhosis which poses a significant health problem worldwide. At the cellular and molecular level, this progressive process is characterized by cellular activation of hepatic stellate cells and aberrant activity of transforming growth factor-beta with its downstream cellular mediators. Liver biopsy has been the reference test for assessment of hepatic fibrosis, but because of its limitations, noninvasive markers of liver fibrosis were developed. Liver fibrosis or cirrhosis was considered irreversible in the past but progress of research on the molecular pathogenesis of liver fibrosis has shown that hepatic cellular recovery is possible. Currently, no acceptable therapeutic strategies exist, other than removal of the fibrogenic stimulus, to treat this potentially devastating disease.

Middle Eastern countries, including Saudi Arabia to some extent, are endemic for chronic hepatitis B (CHB) infection which could be associated with high mortality and comorbidities risk. However, limited data characterizing this CHB population exists. Our aim was to characterize and compare CHB patients in 2015 with those in 2010 and 2012 in Saudi Arabia. We conducted and compared three cross-sectional analyses of adult patients with CHB defined as either positive hepatitis B surface antigen or documented CHB history in 2010, 2012, and 2015. Data were accessed from the multicenter Systematic Observatory Liver Disease Registry (SOLID). A total of 765 CHB patients were identified in 2010 (n = 274), 2012 (n = 256), and 2015 (n = 235). Median age was significantly higher in 2015 (47 years) compared to 2010 and 2012 (42 years;P < 0.05). The proportions of patients with hepatocellular carcinoma (range 1-12%) and cirrhosis (range 5-23%) were significantly higher in 2015 compared to 2010 and 2012 (P < 0.05). Compared to 2010, patients in 2015 had significantly (P < 0.05) higher prevalence of coronary artery disease (10% vs. 4%) and hyperbilirubinemia (18% vs. 9%). Although not significant, there was a numerical increase in 2015 in chronic kidney disease (9% vs. 7% in 2010;P= 0.559) and hepatic steatosis (32% vs. 25% in 2010;P= 0.074). Significantly more patients in 2015 (P < 0.05) were treatment experienced (23% vs. 5% in 2010/2012) and switched treatment (17% vs. 1-2% in 2010/2012). Between 2010 and 2015, the CHB population in Saudi Arabia had significantly aged and was more likely to develop liver disease sequelae and other comorbidities.

Metabolic bone disease is common in patients with inflammatory bowel disease (IBD). Our aim was to determine the frequency of bone loss among Saudi patients with IBD and possible contributing risk factors. We retrospectively reviewed Saudi patients with IBD, between 18 and 70 years of age, who had bone mass density (BMD) determined by dual-energy X-ray absorptiometry scanning at one of three hospitals in the Kingdom of Saudi Arabia from 2001 to 2008. Case notes and BMDs results were carefully reviewed for demographic and clinical data. Low bone mass, osteopenia, and osteoporosis were defined according to the WHO guidelines. Predictive factors for BMD were analyzed using group comparisons and stepwise regression analyses. Ninety-five patients were included; 46% had Crohn's disease (CD) and 54% had ulcerative colitis (UC). The average age was 30.9±11.6 years. Using T-scores, the frequency of osteopenia was 44.2%, and the frequency of osteoporosis was 30.5% at both lumbar spine and proximal femur. Only 25.3% of patients exhibited a BMD within the normal range. Our results revealed a positive correlation between the Z-score in both the lumbar spine and the proximal femur and body mass index (BMI) (P=0.042 and P=0.018, respectively). On regression analysis BMI, age, and calcium supplementation were found to be the most important independent predictors of BMD. Saudi patients with IBD are at an increased risk of low BMD and the frequency of decreased BMD in Saudi patients with CD and UC were similar. BMI and age were the most important independent predictors of low BMD.

Complete rectal prolapse (full-thickness, circumferential intussusception of the entire rectal wall through the anal canal) is not a common condition. Furthermore, anorectal giant condyloma acuminata (ConA), a sexually transmitted disease caused by human papilloma viruses, is rarely reported as a cause of rectal prolapse or as occurring in association with it. We report a patient with extensive anorectal ConA who had recurrent rectal prolapse, which became irreducible and required urgent surgery for reduction and perianal and abdominal rectopexy.

A 51-year-old woman, mother of six children, presented with longstanding history of extensive perineal and vaginal Con A for 15 years, which has been proved by microbiology, immunology, and histological examination to be due to human papilloma virus (HPV) with occasional concomitant candidal infection. Other causes include increased intraabdominal pressure, a deep pouch of Douglas, weakness of the pelvic floor, decreased resting anal sphincter pressure, neurological disorders, and some parasitic infections (amebiasis and schistosomiasis).
