Abstract

High-resolution ultrasound has been used as an important tool in the diagnosis, management and monitoring of both acute and chronic peripheral nerve injuries. According to literature, it demonstrated high sensitivity and specificity for the detection of specific pathologies and its ability to differentiate between them. Literature has been reviewed, summarizing the specific finding of such modality in various peripheral neuropathies and with a specific focus over its role in evaluation and management of traumatic peripheral neuropathies.

Abstract

Objective: This study aimed to evaluate the mortality pattern in children seen at Federal Medical Centre Umuahia (FMCU) Abia state, South Eastern Nigeria.

Methods: A retrospective cross sectional descriptive study over a 5-year period from January 1, 2004 to December 31, 2008 using data retrieved from the hospital’s medical records department.

Results: A total of 3,814 children were admitted in the hospital and 434 of them died giving a mortality rate of 11%. The mean age was 1.7 (Std D of 3.19). Two hundred and thirty eight of them were males while 196 of them were females giving a sex ratio of 1.2:1. Majority of the mortality (49%) occurred within 24 hours of admission. The major causes of death during neonatal period were birth asphyxia (34%), prematurity (24%) and neonatal sepsis (24%). Malaria was the leading cause of death beyond the neonatal period accounting for 42% of cases. Other common mortality causes were pneumonia, septicaemia, diarrhea, HIV AIDS and meningitis each accounting for 10%, 10%, 7%, 7% and 5% respectively. The months of July, May and March accounted for most deaths (12%, 12% and 11% respectively).

Conclusion: Birth asphyxia and malaria associated deaths were responsible for most deaths during neonatal and beyond neonatal periods respectively. Presence of trained personal at all deliveries will help to reduce neonatal asphyxia. Efforts should be made to reinforce the existing effective malaria control tools.

Abstract

Objective: This study aimed to assess the risk factor profile of shoulder dystocia and associated neonatal complications in Oman, a developing Arab country.

Methods: A retrospective case-control study was conducted among 111 cases with dystocia and 111 controls, identified during 1994-2006 period in a tertiary care hospital in Oman. Controls were randomly selected among women who did not have dystocia, and were matched to cases on the day of delivery. Data related to potential risk factors, delivery, and obstetric complications were collected.

Results: Dystocia was significantly associated with older maternal age, higher parity, larger BMI, diabetes, and previous record of dystocia. In addition, dystocia was associated more with vacuum and forceps deliveries. Routine traction (51%) was the most usedmanoeuvre. Among dystocia cases, 13% were associated with fetal complications of which Erb’s Palsy was the most prevalent (79%).

Conclusion: Our finding of significant associations with risk factors lays out the ground to develop a predictability index for shoulder dystocia, which would help in making it preventable. Further prospective studies are required to confirm the obtained results.

Abstract

Objective: To determine the efficacy of topical curcumin in reducing breast inflammation in women suffering from lactational mastitis.

Methods: A randomized double-blind, placebo-controlled study including 63 breastfeeding women with lactational mastitis were randomly assigned to receive curcumin topical cream, one pump every 8 hours for 3 days (n=32) or topical moisturizer as placebo (n=31). Using an index for severity of breast inflammation, all of the patients had moderate breast inflammation before entering the study. The outcome of treatment was evaluated using the same index at 24, 48 and 72 hours of starting the treatment.

Results: There was no significant difference between two study groups regarding the baseline characteristics such as age (p=0.361) and duration of lactation (p=0.551). After 72-hour of therapy, patients in curcumin groups had significantly lower rate of moderate (p=0.019) and mild (p=0.002) mastitis. Patients in curcumin group had significantly lower scores for tension (p<0.001), erythema (p<0.001) and pain (p<0.001), after 72-hour of treatment.

Conclusion: The results of the current study indicate that topical preparation of curcumin successfully decrease the markers of lactational mastitis such as pain, breast tension and erythema within 72 hours of administration without side effects. Thus, topical preparation of curcumin could be safely administered for those suffering from lactational mastitis after excluding infectious etiologies.

Abstract

Objective: The purpose of this study was to determine the prevalence of vancomycin-resistant Staphylococcus aureus isolated from clinical samples in Shiraz hospitals.

Methods: From March to December 2012, 100 S. aureus isolates (mainly from wound and blood) were collected from three hospitals in Shiraz, south of Iran. After identification of Staphylococcus aureus by biochemical, microbiological and molecular methods, antibiotic susceptibility testing was performed by Kirby-Bauer disc diffusion test for 13 different antibiotics. Vancomycin-resistant Staphylococcus aureus isolates were determined by vancomycin agar screening test and PCR for vancomycin resistant genes (vanA and vanB).

Results: The lowest and highest resistance was seen for quinupristin-dalfopristin (n=1) and ampicillin (n=95), respectively. Vancomycin agar screening test showed that 37 isolates can grow on these media. Further study by PCR also detected vanA and/or vanB genes in all of these strains. Also, 19 isolates showed either vanA or vanB but were susceptible according to vancomycin agar screening test. In total,vanA and vanB resistant genes were detected in 34% and 37% of clinical isolates, respectively.

Conclusion: The results showed that the frequency of vancomycin resistance genes (vanA, vanB) is very high in Staphylococcus aureusstrains isolated from patients in south of Iran. Thus, urgent interventions are needed to keep the emergence and transmission of these isolates to a minimum.

Abstract

Objective: The objective of the present study is to determine the incidence of delirium and the associated factors in patients undergoing open heart surgery.

Methods: This is an Analytic-descriptive study conducted on 404 patients undergoing elective open heart surgery in Fatemeh Zahra Heart Center, Sari, over the period of 6 months from July to December 2011. Sampling was achieved in a nonrandomized targeted manner and delirium was assessed using NeeCham questionnaire. A trained nurse evaluated the patients for delirium and completed the risk factor checklist on days 1 to 5 after surgery. Data analyses were accomplished using survival analysis (Kaplan-Meier and Cox regression) on SPSS software version 15.

Results: We found that variables, including ventilation time, increased drainage during the first 24 hours, the need for re-operation in the first 24 hours, dysrhythmias, use of inotropic agents, increased use of analgesics, increased arterial carbon dioxide, lack of visitors, and use of physical restrainers were associated with the development of delirium. In addition, we found a delirium incidence of 29%.

Conclusion: Diagnosis of cognitive disorders is of utmost value; therefore, further studies are required to clarify the risk factors because controlling them will help prevent delirium.

Abstract

Objective: To assess the relationship of bacterial and fungal contamination on used surgical masks worn by the hospital personnel and microbial air quality in their working wards.

Methods: This is a cross-sectional study of 230 used surgical masks collected from 214 hospital personnel, and 215 indoor air samples collected from their working wards to culture for bacterial and fungal counts. This study was carried out at the hospital in Bangkok. Group or genus of isolated bacteria and fungi were preliminarily identified by Gram’s stain and lacto-phenol cotton blue. Data were analyzed using paired t-test and Pearson’s correlation coefficient at the significant level of p<0.050.

Results: Means and standard deviation of bacterial and fungal contamination on inside area of the used masks were 47 ± 56 and 15 ± 9 cfu/ml/piece, and on outside area were 166 ± 199 and 34 ± 18 cfu/ml/piece, respectively, p<0.001. The bacterial and fungal contamination on used masks from hospital personnel working in the male and female medical wards and out-patient department, as well as the bacterial and fungal counts of the indoor air sample collected from the same area were relatively higher than the other wards. The predominant isolated bacteria and fungi contaminated on inside and outside areas of the used masks and air samples were similar (Staphylococcus spp. and Aspergillus spp.; respectively). For its relationship, results found that bacterial and fungal counts in air samples showed significantly positive correlation with the bacterial contamination load on outside area of the used masks, r=0.16, p=0.018 and r=0.21, p=0.003, respectively.

Conclusion: High bacterial contamination on outside area of the used masks was demonstrated, and it showed a significant correlation with microbial air quality of working wards.

Abstract

Objective: This study aimed at evaluating the prevalence, pattern and predisposing factors for hepatic adverse effects with statins in a regional hospital in Sultanate of Oman.

Methods: A retrospective review of the patient files in Department of Medicine during the year 2011 was done to evaluate any hepatic dysfunction possibly related to statins among the patients. For each case of suspected statin induced hepatic effect, additional details on temporal relationship, pattern of presentation, management, final outcome and any contributing factors were obtained. Difference in the occurrence of hepatic effects based on the patient demographics and drug characteristics was additionally evaluated.

Results: A total of 927 patients meeting the inclusion criteria were included for the study. Mean age of the evaluated patients was 63.1 ± 11.37 and median duration of use of statin in months was 22 (IQR, 43.25). In 40 (4%) of the 927 patients, there was presence of a hepatic effect considered to be statin related and only in 12 (1%) patients a significant transaminase rise (>3 times) was observed. Median duration of use of statin among those patients who developed suspected statin induced hepatic effects and those who did not was 45 (IQR,52) and 21 (IQR, 43) months, respectively and the difference observed was statistically significant. A significant difference in the prevalence of hepatic effects was observed only based on the duration of statin use.

Conclusion: There was an infrequent occurrence of significant hepatic effects associated with statins in the study population. Our results support the latest recommendations including from United States Federal Drug Administration (US FDA) that statins appear to be associated with a very low risk of serious liver injury and that routine periodic monitoring of transaminases does not appear to detect or prevent serious liver injury in association with statins.

Abstract

Objective: To describe the epidemiology of acute pancreatitis in a tertiary care center in Oman.

Methods: A retrospective study evaluated all adults (>18 yrs) who presented with first attack of acute pancreatitis to SQUH from 1^st of January 2006 to 31^st of December 2012.

Results: One hundred seventy-four patients were found. The mean age of the cohort was 44 ± 11 years. 54% (n=95) were male and 45% (n=79) were female. Majority of the cases were mild (n=131) compared to moderate (n=29) and severe (n=14). Sixty six percent (n=116) of the cases were secondary to alcohol and biliary tract diseases. Alcoholic pancreatitis occurred in 53% of the males whereas biliary pancreatitis occurred in 51% of the females. Pancreatitis recurred in 40% (n=71) of the cases, especially in alcoholic pancreatitis. 56 patients (32%) had complications, especially in the severe cases.

Conclusion: The data about acute pancreatitis in Oman was similar to the Western countries. Pancreatitis occurred in males more than females. Alcoholic pancreatitis was more common in males, whereas biliary pancreatitis was more common in females. Alcoholic pancreatitis re-occurred in nearly half of the cases. Severe cases were associated with more complications and recurrence.

Abstract

Carcinoid tumors are relatively rare and can occur in the thorax, abdomen, or pelvis. Functional imaging in the form of Indium-111 pentetreotide scanning is widely used for identification of these tumors and it exploits the fact that the vast majority of these tumors express somatostatin receptors on their cell membrane. In this report, we present a case of a 76-year-old man who was diagnosed with peritoneal carcinomatosis. The findings of the initial imaging made by planar and single photon emission computed tomography were misleading and the actual diagnosis was only made by single photon emission computed tomography/computed tomography.

Abstract

Traumatic rupture of the thoracic aorta is a leading cause of death, following major blunt trauma, and endovascular repair has evolved as a viable alternative to open repair. This report highlights the role of transesophageal echocardiography as a valuable imaging tool for locating the exact position of the lesion, guiding placement of the endograft, detecting leaks around it and supplementing information derived from angiography during endograft deployment.

Abstract

Fibrodysplasia ossificans progressiva formerly known as Myositis ossificans progressiva is a rare hereditary mesodermal disorder. It is characterized by congenital skeletal anomalies and progressive ectopic bone formation in connective tissue, resulting in mature ossification within soft tissues and bridging between osseous structures. It is extremely rare and has an incidence of one in two million people. Usually, it has typical clinical and radiographic features. Here, we present a case of a young patient diagnosed to have an advanced fibrodysplasia ossificans progressiva. Plain radiographs provide characteristic findings, and radiologists may play a major role in diagnosing and preventing invasive procedures or further traumatic insults to the affected patient. Though rare, diagnosis of fibrodysplasia ossificans progressiva should be considered whenever characteristic radiographic features of multifocal heterotopic bone formation is seen along with the valgus deformities of the big toes. Being a rare condition, treatment guidelines are not clear and this condition needs further research.

Abstract

Pregnancy luteoma is a non-neoplastic lesion of the ovary occurring during pregnancy and is usually discovered incidentally at the time of a cesarean section or during postpartum tubal ligation. An accurate diagnosis is important for the mother and the fetus as it can be confused with ovarian malignancy leading to unnecessary surgery. We report a case of a pregnant female who was discovered to have bilateral enlarged ovaries at the time of emergency cesarean section.

Keywords: Pregnancy; Luteoma.

Abstract

Diaphragmatic injury following blunt thoracoabdominal trauma is rare and usually associated with key radiological features like dependent viscera sign, collar sign, diaphragmatic thickening and defects. It may also be associated with secondary signs like intrathoracic herniation of abdominal viscera. Diaphragmatic crura, which are attached to the upper lumbar vertebra represent prominently thickened folds along the posterior diaphragm, are usually inconspicuous on routine CT scans. We present a case of a young patient who sustained a motor vehicle accident and developed difficulty in breathing. CT scan of the patient revealed bilateral crural hematomas, with splenic and renal lacerations and no other sign of diaphragmatic injury. The patient was operated and blunt diaphragmatic rupture was confirmed at surgery.

Abstract

Müllerian agenesis (Mayer-Rokitansky-Küster-Hauser syndrome) is typically described as missing uterus and fallopian tubes with malformation of the upper vagina. Isolated uterine anomaly is a rare variant of the syndrome. A 16-year-old female with primary amenorrhea and rudimentary uterus on the magnetic resonance imaging (MRI) was reported. The ovaries, vaginal canal and other abdominal and pelvic organs were normal. The patient’s sexual, physical and developmental characteristics were normal. The serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, prolactin, testosterone and thyroid-stimulating hormone (TSH) were also normal. Thus, this patient represents an important variant of the Müllerian agenesis syndrome. 

Abstract

Renal graft thrombosis is a serious and devastating complication of renal transplant that ultimately results in graft loss. It is associated with acute and hyper-acute rejections; however, the underlying cause in large proportion of patients remains unknown. We report a case of a young male who underwent live related kidney transplant but lost the graft on the operating table due to renal vein thrombosis (RVT).

Abstract

Pfeiffer syndrome is a rare genetic disorder with combination of bicoronal craniosynostosis, broad thumbs, broad great toes, ankylosis of elbow and partial variable syndactyly of the hands and feet. Since the disorder was reported by Pfeiffer in 1964, new associations have been added on. Authors report a newborn with features of Pfeiffer syndrome type 3 with hypothyroidism, tail like appendage and extremely anteriorly placed anus as new associations.

Abstract

Objective: Neonates usually acquire Group B streptococcal infection vertically from the maternal birth canal during delivery. In January 2010, a Group B streptococcal outbreak investigation was conducted in response to an increased number of clinical specimens from our neonatal intensive care unit.

Methods: Microbiology laboratory records were reviewed to identify Group B streptococcal from specimens originating from the neonatal intensive care unit during December 2009 and January 2010. Patients from whom these specimens were collected were identified and their charts reviewed. Environmental samples to screen for Group B streptococcal were collected from the unit, clinical and environmental isolates were compared by pulsed field gel electrophoresis. Point prevalence screening was conducted twice before declaring the outbreak over.

Results: Pulsed field gel electrophoresis patterns of three clinical strains from six patients were indistinguishable. One environmental strain was isolated from one of the patients monitor, and had identical pulsed field gel electrophoresis pattern to that of the three clinical strains. Infection control measures were implemented in the neonatal intensive care unit and follow-up point prevalence screening identified no new cases.

Conclusions: Although poor infection control practice has been implicated in previous reports of nosocomial outbreaks of Group B streptococcal infection in neonatal intensive care units, our finding provides unique evidence that the environment can act as a reservoir of Group B streptococcal and play a key role in nosocomial transmission.
