RESUMO
As the Middle East respiratory syndrome coronavirus (MERS-CoV) continues to occur in small outbreaks in Saudi Arabia, we aimed to assess the knowledge, attitudes and intended practices of healthcare workers (HCWs) during the early stage of the COVID-19 pandemic and compare worry levels with previous findings during the MERS-CoV outbreak in 2015. We sent an adapted version of our previously published MERS-CoV questionnaire to the same cohort of HCWs at a tertiary hospital in Saudi Arabia. About 40% of our sample had previous experience with confirmed or suspected MERS-CoV patients, and those had a significantly higher knowledge score (13.16 ± 2.02 vs. 12.58 ± 2.27, P = 0.002) and higher adherence to protective hygienic practices (2.95 ± 0.80 vs. 2.74 ± 0.92, P = 0.003). The knowledge scores on COVID-19 were higher in the current cohort than the previous MERS-CoV outbreak cohort (68% vs. 79.7%, P < 0.001). HCWs from the current cohort who felt greater anxiety from COVID-19 compared to MERS-CoV were less likely to have been exposed to MERS-CoV infected/suspected cases (odds ratio (OR) = 0.646, P = 0.042) and were less likely to have attended the hospital awareness campaign on COVID-19 (OR = 0.654, P = 0.035). We concluded that previous experience with MERS-CoV was associated with increased knowledge and adherence to protective hygienic practices, and reduction of anxiety towards COVID-19.

To study the varying presentations, risk factors, and treatment outcomes among patients with physician-diagnosed brucellosis. This retrospective analysis evaluated all cases of brucellosis reported at King Khalid University Hospital during 2003-2013. Data were retrieved from patient records and a laboratory information system. Descriptive statistics were generated to summarize the study variables. Fisher's exact test or Pearson's chi-square test was used to compare categorical variables. Out of 163 patients identified with brucellosis, 76.7% of patients were culture positive. Fever was the most frequent symptom (85.9%), followed by arthralgia (46.6%). The most common clinical signs was splenomegaly (12.9%), followed by hepatomegaly (11.0%). Laboratory investigations revealed lymphocytosis and anemia in 66.3% and 55.2% of the patients, respectively. Approximately half of the patients (47.8%) had high erythrocyte sedimentation rates, and 56.4% had neutrophilia. Raw milk consumption and direct contact with animals were reported by 45.4% and 16.0% of patients, respectively. Treatment failure and relapse were observed in 8 (5.7%) cases. All treatment failures and relapses occurred among children <= 10 years of age or adults > 45 years old (11.0% vs. 0%; p = 0.006). Our findings demonstrate that raw milk consumption can be a substantial factor in brucellosis prevention in Saudi Arabia. Laboratory findings, along with the observed pattern in clinical signs and symptoms, can potentially mean underdiagnosis of mild cases. Age was the only factor associated with unfavorable treatment outcomes.
RESUMO
OBJECTIVE: The bacille Calmette Guérin (BCG) vaccine is administered worldwide to prevent tuberculosis. Although, Post BCG vaccination complications like disseminated BCG infections are rare and immunocompromised children are at high risk of developing BCG-related complications including BCG-lymphadenitis and other disseminated diseases. PATIENTS AND METHODS: This was a prospective study of children who developed disseminated BCG after vaccination who were admitted in three tertiary care hospital in Riyadh, Saudi Arabia, in the year 2015. The clinical presentation, microbiological/immunological evaluation and outcome will be discussed. RESULTS: 12 cases (7 males and 5 females) of disseminated BCG infections after vaccination were documented with age ranges 3 and 32 months. Eight (66%) patients had interleukin IL-12 deficiency and 3 (25%) had severe combined immune deficiency (SCID) and 1 (8%) had Interferon gamma receptor II deficiency. 9 (75%) patients presented with generalized lymphadenopathy. Hepatosplenomegaly was present in 6 (50%) patients. 2 (16%) patients presented with a recurrent skin infection and persistent oral candidiasis in one patient and pneumonia in the other. Five (41%) families were from 1st degree consanguineous marriage. Tuberculosis (TB) culture and sensitivity were positive for Mycobacterium bovis from gastric aspirate (GA) in 4 patients and the lymph node in 9 patients and 1 patient had culture positive from both skin lesion and lymph nodes. Mycobacterium bovis PCR was positive in 4 patients. All patients received anti-tuberculosis therapy; all patients survived except one who died due to multi-organ failure. CONCLUSIONS: These results indicate that the prevalence of disseminated BCG vaccine in immunocompromised Saudi children is significantly high. Since in our region we have a high consanguinity rate and a high number of primary immune deficiency disorder (PID), we believe that BCG vaccination should be postponed till a child reaches one-year-old and appropriate tests exclude the diagnosis of primary immunodeficiency diseases.

BACKGROUND: The World Health Organization (WHO) has recommended Bacillus Calmette-Guerin (BCG) vaccination as a part of the global expanded program for immunization. Although the BCG vaccine is usually a safe vaccine, a number of complications with lymphadenitis being the most common complication, can occur. AIM: We evaluated the frequency, the clinical presentation and treatment modalities of lymphadenitis after BCG vaccine in Saudi children. RESULTS: A total of 145 patients with BCG lymphadenitis presented between January 2005 and December 2010. In the majority (103) of the cases, the lymphadenitis involved ipsilateral left axillary nodes. Other sites of involvement included the left supraclavicular lymph nodes in 26 (18%) patients, and both the left axillary and supraclavicular lymph nodes were involved in 7 cases (4.8%). A total of 75 patients (65%) were given antituberculous medication. Eight (27%) patients had positive acid-fast bacilli and positive cultures for Mycobacterium bovis. CONCLUSION: In light of the findings of this study, it would be advisable to administer the BCG vaccine in Saudi Arabia at a time later than at birth, as the younger children are commonly affected.
