A pattern of antibiotic drug resistance of Salmonella Typhi and Salmonella Paratyphi among children with enteric fever in a tertiary care hospital in Lahore, Pakistan.

AIM: To establish the pattern of antibiotic resistance and assess the frequency of multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains of Salmonella Typhi and Salmonella Paratyphi among children with enteric fever. METHODS: This cross-sectional study was carried out in the Department of Pediatrics, Sharif Medical City Hospital, Lahore, from July 2020 to January 2021. The study involved patients aged between 0 to 15 years who attended our outpatient department or were admitted to the ward with the suspicion of typhoid fever. A convenience sample of patients with blood cultures positive for S. Typhi and S. Paratyphi was enrolled. RESULTS: Of the 105 participants, 70 (66.7%) were male. The mean age was 8.48±4.18 years, and the most affected age group was 6-10 years (n=46, 43.8%). Among the cultured organisms, 95 (90.5%) isolates were S. Typhi and 10 (9.5%) were S. Paratyphi A. Antibiotic resistance was highest against ampicillin (n=91, 86.7%), and all of the isolates were sensitive to imipenem and meropenem. Twenty-three (21.9%) cultured organisms were MDR and 54 (56.8%) were XDR. CONCLUSION: An alarming antibiotic drug resistance pattern was observed among children with enteric fever in Lahore. The lowest resistance was noted for azithromycin, meropenem, and imipenem. Our findings warrant the immediate implementation of tailored antibiotic stewardship and infection control strategies.

Assessment of upper to lower body segment ratio and arm span to height difference in school children of Lahore.

Objective: To assess upper-to-lower body segment ratio and arm span to height difference in children. METHODS: The descriptive, cross-sectional study was conducted in schools of the Raiwind area near Lahore, Pakistan, from November 2021 to May 2022, after approval from the ethics review committee of the Sharif Medical and Dental College, Lahore. The sample comprised children aged 3-14 years whose height fell between the 3rd and 97th centiles on the Centers for Disease Control and Prevention height-for-age chart. Data was analysed using SPSS 23. RESULTS: Of the 1,836 children, 906(49.3%) were boys with mean age 8.45±3.02 years, mean height 132.54±17.78cm and mean weight 32.0±13.72kg. Besides, there were 930(50.7%) girls with mean age 8.26±3.21 years, mean height 130.41±18.03cm and mean weight 31.09±13.88kg. The mean upper-to-lower body segment ratio in boys was 1.06±0.15 at age 3 years, 0.96±0.08 at age 7 and 0.94±0.08 at age 10. The mean upper-to-lower body segment ratio in girls was 1.08±0.08 at age 3 years, 0.98±0.07 at age 7, and 0.92±0.10 at age 10. The mean arm span to height difference in boys was -1.81±5.83 and in girls -4.09±5.77. Conclusion: Upper-to-lower body segment ratio and arm span to height difference may help paediatricians in the evaluation of disproportionate short stature.

Caudal Regression Syndrome - a rare congenital disorder: A case report.

Caudal regression syndrome is a rare anomaly that is characterised by impaired development of the lower half of the body. This includes absent or abnormal development of lumbar and sacrococcygeal segments. Other associations of this disease include abnormalities of genitourinary tract, gastrointestinal tract, and cardiopulmonary system. The exact aetiology is unknown and is believed to be multifactorial but maternal diabetes is significantly linked to this rare disorder. We report the case of a new-born baby boy with caudal regression syndrome, hyperbilirubinaemia and patent ductus arteriosus.
