RESUMO

Corynebacterium spp. are Gram-positive bacteria, and recent studies have proposed a potential link between granulomatous mastitis and Corynebacterium kroppenstedtii infections, posing a challenge in selecting appropriate antibiotics, particularly in pregnant women. A young pregnant woman presented with a palpable lump in her left breast. Subsequent assessment revealed the presence of necrotising granulomatous mastitis attributed to C. kroppenstedtii. Initially treated with amoxicillin/clavulanate, the patient showed no improvement. Consequently, clindamycin was administered based on culture and sensitivity results, which resulted in a favourable response with no recurrence of symptoms. This report aims to emphasise the efficacy of clindamycin as a treatment option for granulomatous mastitis caused by C. kroppenstedtii. LEARNING POINTS: Alternative antibiotics for treatment of granulomatous mastitis can be effective.The safety and efficacy of antibiotics in pregnancy is important.

RESUMO

Background The daily morning round is a routine activity performed by medical teams. During the morning round, updates on the patient's clinical condition, new laboratory results, and other test results are reviewed and discussed between team members, the patient, and at times the family. Completing these tasks takes time. The design of the patient location differs between hospitals, and significant distance between patients can considerably affect round times. This study assesses physicians' time spent on clinical activities, the distance traveled, and the time they spend walking between patients during daily morning rounds to identify better reorganization methods to reduce wasted time. Methodology The survey was self-administered and had no intervention needing ethical approval. The research team's leader engaged two observers (a general practitioner from another department and a general internal medicine department case manager) to collect the data. The general practitioner was a medical graduate doctor, while the bed manager was not a medical college graduate. They observed 10 rounds over 10 non-consecutive days from July 1 to July 30, 2022. They recorded daily activities during the daily morning round, including time spent with patients, family conversations, bedside education, medication, social issues, and the time and distance required to move from patient to patient and from one location to location. The informal conversations about age, work history, and other small talk were recorded and converted into quantitative data. In each round, records were given to a statistician for rechecking. Subsequently, the records were imported into a Microsoft Excel spreadsheet for further statistical analysis. For continuous variables, the data were summarized as mean, median, and standard deviation. For categorical variables, the data were summarized as counts or proportions. Results On average, the duration of the daily morning round was 161.7 ± 17.3 minutes. The average number of patients seen by the general internal medicine round team was 14. The median patient encounter time per patient was 14 minutes (11-19 minutes), with an average of 12 minutes. An average of 8.6 employees participated in the 10-day rounds. The physician spent 41.2% of the time in direct contact with the patient during the morning round, 11.4% in maintaining electronic medical records, and 18.20% in bedside teaching. Additionally, 7.1% of the round time was spent because of interruptions by clinical and non-clinical staff other than team members or family members who were not in the room. Furthermore, a team member walked an average of 763 ± 54.5 m (667-872 m) per round, costing 35.7 minutes (22.1%) of the total round time. Conclusions The daily morning round time was significantly longer compared with the reported round times. Relocating patient beds to a common location reduced the rounding time by 22.30%. Disruption, teaching, and medical instruction must also be considered and shortened to reduce the morning round time.

RESUMO

We report a case of rhabdomyolysis associated with Mycoplasma pneumoniae pneumonia in a 37-year-old Sri Lankan man who presented to the emergency department with complaints of feverishness, shortness of breath, cough, and generalised muscle pain. He had a serum creatinine kinase of 14 220 U/L, serum myoglobin of 1822 ng/mL, and serum creatinine of 195 µmol/L. His chest X-ray revealed bibasilar interstitial infiltrates. The antimycoplasma antibody titre was high. The patient was successfully treated with aggressive intravenous fluid replacement and azithromycin. The outcome was rapidly favourable, allowing us to discharge the patient 12 days after admission. On discharge, the serum creatinine kinase was 924 U/L and the creatinine was 126 µmol/L; the chest examination was unremarkable.

RESUMO

Hypertension (HTN) is common in chronic kidney disease (CKD), and it may aggravate CKD progression. The optimal blood pressure (BP) value in CKD patients is not established yet, although systolic BP ≤130 mmHg is acceptable as a target. Continuous BP monitoring is essential to detect the different variants of high BP and monitor the treatment response. Various methods of BP measurement in the clinic office and at home are currently used. One of these methods is ambulatory BP monitoring (ABPM), by which BP can be closely assessed for even diurnal changes. We conducted a non-systematic literature review to explore and update the association between high BP and the course of CKD and to review various BP monitoring methods to determine the optimal method for BP recording in CKD patients. PubMed, EMBASE, Google, Google Scholar, and Web Science were searched for published reviews and original articles on BP and CKD by using various phrases and keywords such as "hypertension and CKD", "CKD progression and hypertension", "CKD stage and hypertension", "BP control in CKD", "BP measurement methods", "diurnal BP variation effect on CKD progression", and "types of hypertension." We evaluated and discussed published articles relevant to the review objective. Before preparing the final draft of this article, each author was assigned a section of the topic to read, research deeply, and write a summary about the assigned section. Then a summary of each author's contribution was collected and discussed in several group sessions. Early detection of high BP is essential to prevent CKD development and progression. Although the latest Kidney Disease Improving Global Outcomes (KDIGO) guidelines suggest that a systolic BP ≤120 mmHg is the target toprevent CKD progression, systolic BP ≤130 mmHg is universally recommended.ABPM is a promising method to diagnose and follow up on BP control; however, the high cost of the new devices and patient unfamiliarity with them have proven to be major disadvantages with regard to this method.

RESUMO

(1) Background: Qatar does not have any indigenous cases of dengue; however, the influx of immigrants from dengue endemic countries, the environment, and climate suitability for Aedes vector mosquitoes suggest a potential risk for local transmission. In this study, we investigated various demographic factors to determine the epidemiological features of dengue in Qatar. (2) Methods: In the present retrospective study, we reviewed dengue notification data received at the national surveillance system, Ministry of Public Health, Qatar, between January 2013, and December 2021, and we analyzed the incidence of the dengue disease burden to identify factors that could contribute to the dissemination of the disease in Qatar. (3) Results: A total of 166 dengue fever seropositive cases were recorded during the study period in Qatar. The mean incidence was estimated to be 0.7/100,000 population, which increased from 0.7/100,000 in 2013 to 1.5/100,000 in 2019. The majority of the cases were male, between 20-50 years of age and notified during the hot months (June-September). Most of the patients had fever without hemorrhagic manifestations. There were no dengue related deaths during 2013-2021. (4) Conclusion: Dengue fever occurred more frequently among men than women, and its incidence is low among Qatari nationals. The presence of the most efficient vector, Aedes aegypti, in Qatar, if confirmed, poses a risk of local outbreaks. Therefore, regular vector surveillance is needed to assess the distribution, biting habits and abundance of vector mosquito species and the risk for mosquito-borne diseases.

RESUMO

Disseminated tuberculosis (TB) is a life-threatening disease resulting from the hematogenous spread of Mycobacterium tuberculosis. The diagnosis is challenging owing to its subtle nonspecific clinical presentation, which usually reflects the underlying organ involved. Besides, tools for confirmatory laboratory diagnosis are limited. Therefore, a high index of suspicion is required for early diagnosis. Miliary pattern on chest radiography is a common finding that has an important role in the early detection of the disease. Nevertheless, approximately 10%-15% of patients have normal chest radiography. Although abnormalities are present, basic hematologic and biochemical tests as well as tuberculin skin test are nonspecific for the diagnosis. Imaging studies are helpful adjunct tools for disseminated TB as they can help determine the involved sites and guide technicians to obtain appropriate specimens for diagnosis. Clinical confirmation of the diagnosis of disseminated TB is usually based on bacteriological or histological evidence. Response to first-line anti-TB drugs is good as evidenced by many reports. This review aims to present a current update on disseminated TB with emphasis on the diagnostic workup of this devastating condition.

RESUMO

Myocarditis as a result of malaria infection is uncommon. However, we report a case of a Pakistani emigrant who presented with respiratory distress, fever, chills, and nausea at the emergency room. The patient had traveled to visit his relatives in Pakistan without receiving antimalarial chemoprophylaxis. (Travel clinic advises travelers to Pakistan to take antimalarial drugs as prophylaxis.) Cardiorespiratory examination revealed bilateral crepitation in all lung fields, as well as triple heart sounds. Examination of blood smear showed trophozoites and schizonts of Plasmodium vivax with low parasite density. Echocardiography showed diffuse hypokinesia with an ejection fraction of 22% consistent with acute myocarditis. The patient was given chloroquine phosphate, digoxin, perindopril arginine, furosemide, and spironolactone and gradually improved.

RESUMO

BACKGROUND: Qatar is located on the north-eastern coast of the Arabian Peninsula. Qatari natives account for less than 15% of the population while the largest migrant group comprising 60% derives from South Asia. Despite projections that stroke burden in Qatar will increase with population ageing, epidemiological studies focusing on stroke in Qatar are relatively scarce. METHOD: We reviewed the available epidemiological publications relating to Qatar. In addition, we have added to this knowledge by incorporating Qatari data from the on-going Bio-Repository of DNA in Stroke, an independent multinational database of stroke patients. RESULTS: Qatar has low reported incidence and mortality rates of 58 and 9.17 per 100,000 per year, respectively, which may be explained by its middle-aged migrant worker majority population. Correspondingly, South Asian migrants in Qatar suffered younger strokes than Qatari natives (48.7 vs 63.4 years, P < 0.001). Among the most common risk factors identified in stroke patients were hypertension (77.9%), diabetes (43.8%) and hypercholesterolemia (28.5%). Ischaemic stroke was the most frequent subtype amongst migrant South Asians (71.1%). The majority of stroke cases had computed tomography and/or magnetic resonance imaging scans, but only 11.1% of ischaemic strokes were thrombolysed. Qataris on one-year follow up were more often found to have died (6.5% vs 0.3%) and had further stroke/transient ischaemic attack events (17.4% vs 6.4%, P = 0.009) compared to South Asians. CONCLUSION: The burden of stroke is increasing in Qatar, and considerable disparities are observed between the native and migrant populations which likely will require different approaches to management by its healthcare system.

RESUMO

Malaria remains a significant public health challenge and is of global importance. Imported malaria is a growing problem in non-endemic areas throughout the world and also in Qatar due to a massive influx of migrants from endemic countries. Antimalarial drug resistance is an important deterrent in our fight against malaria today. Molecular markers mirror intrinsic antimalarial drug resistance and their changes precede clinical resistance. Thus, in the present study, molecular markers of sulphadoxine-pyrimethamine (Pfdhfr and Pfdhps) and artemisinin (PfATPase6 and Pfk13) were sequenced to determine the drug resistance genotypes among 118 imported P. falciparum isolates in Qatar, between 2013 and 2016. All the isolates had mutant Pfdhfr alleles, with either double mutant (51I/108N) (59.3%) or triple mutant (51I, 59R and 108N) (30.6%) genotypes. I164L substitution was not found in this study. In case of Pfdhps, majority of the samples were carriers of either single (S436A/ A437G/ K540E) mutant (47.2%) or double (S436A/K540E, A437G/K540E, K540E/A581G) mutant (39.8%). A single novel point mutation (431V) was observed in the samples originated from Nigeria and Ghana. Polymorphisms in PfATPase6 were absent and only one non-synonymous mutation in Pfk13 was found at codon G453A from a sample of Kenyan origin. High levels of sulphadoxine-pyrimethamine resistance in the present study provide potential information about the spread of antimalarial drug resistance and will be beneficial for the treatment of imported malaria cases in Qatar.

RESUMO

Imported malaria has been a great challenge for public health in Qatar due to influx of large number of migrant workers. Antimalarial drug resistance has emerged as one of the greatest challenges facing malaria control today. Monitoring parasite haplotypes that predict susceptibility to major antimalarial can guide treatment policies. This study aimed to determine molecular drug resistance pattern in imported malaria cases in Qatar. Blood samples from the uncomplicated P. falciparum malaria patients were collected at Hamad General Hospital, HMC, Doha, Qatar. The samples were further confirmed by nested-polymerase chain reaction (PCR) for P. falciparum. Molecular markers of chloroquine (Pfcrt and Pfmdr1) were analyzed by using nested PCR- RFLP method to determine the key point mutations associated with chloroquine (CQ) drug resistance. A total 118 blood samples were positive for P. falciparum. Overall, by RFLP, 72% harboured wild type allele (N86) of Pfmdr1 gene. The prevalence of Pfcrt mutant (T76), WT (K76) and mixed alleles (K76T) was 63.6% (n = 75), 22.9% (n = 27) and 13.5% (n = 16), respectively. Mean parasitaemia level was higher among the wild type alleles of Pfcrt gene as compared to the mixed/mutant alleles whereas mixed alleles of Pfmdr1 gene having high parasitaemia. Molecular surveillance strategy based on imported malaria cases can be used to detect and track CQ drug-resistant malaria. The data presented here might be helpful for enrichment of molecular surveillance of antimalarial resistance and will be useful for developing and updating antimalarial guidance for non-immune imported cases in Qatar.

RESUMO

Plasmodium vivax is the most prevalent parasite worldwide, escalating by spread of drug resistance. Currently, in Qatar, chloroquine (CQ) plus primaquine are recommended for the treatment of P. vivax malaria. The present study examined the prevalence of mutations in dihydrofolate reductase (dhfr), dihydropteroate synthase (dhps) genes and CQ resistance transporter (crt-o) genes, associated with sulphadoxine-pyrimethamine (SP) and chloroquine resistance, among imported P. vivax cases in Qatar. Blood samples were collected from patients positive for P. vivax and seeking medical treatment at Hamad General Hospital, Doha, during 2013-2016. The Sanger sequencing method was performed to examine the single nucleotide polymorphisms in Pvdhfr, Pvdhps, and Pvcrt-o genes. Of 314 examined P. vivax isolates, 247 (78.7%), 294 (93.6%) and 261 (83.1%) were successfully amplified and sequenced for Pvdhfr, Pvdhps, and Pvcrt-o, respectively. Overall, 53.8% (N = 133) carried mutant alleles (58R/117N) in Pvdhfr, whereas 77.2% (N = 227) and 90% (N = 235) isolates possessed wild type allele in Pvdhps and Pvcrt-o genes, respectively. In addition, a total of eleven distinct haplotypes were detected in Pvdhfr/Pvdhps genes. Interestingly, K10 insertion in the Pvcrt-o gene was observed only in patients originating from the Indian subcontinent. The results suggested that CQ remains an acceptable treatment regimen but further clinical data are required to assess the effectiveness of CQ and SP in Qatar to support the current national treatment guidelines. In addition, limited distribution of genetic polymorphisms associated with CQ and SP resistance observed in imported P. vivax infections, necessitates regular monitoring of drug resistant P. vivax malaria in Qatar.

RESUMO

We report 37-year-old man admitted to the psychiatric ward with acute depression. Antidepressive medications were initiated including: promethazine hydrochloride, hydroxyzine hydrochloride, lorazepam and haloperidol. In an attempt to control his depression, doctors increased the dose of haloperidol. Five days later he developed fever, cough, confusion and he was unable to eat. Accordingly, he was transferred to the medical ward for further assessment. On examination he was febrile, confused, there was neck stiffness and generalized rigidity with flexor planters. Both serum myoglobin and creatine kinase level were elevated. The urine myoglobin test result was positive. He was diagnosed with neuroleptic malignant syndrome. Dantrolene was started for 3 days, followed by bromocriptine. The clinical syndrome resolved over the next couple of days.
