Tetanus; a forgotten infection disease: a report of two cases

BACKGROUND

Tetanus is an infectious disease that can be seen in all age groups in underdeveloped and developing countries, where vaccination programs are inadequate. In developed countries, it is reported more frequently in the adult age group, where the protection of vaccination is diminished and the doses are delayed.

CASE

In this report, we present generalized tetanus, which was observed in two male patients aged 12 and 6 years, admitted at different times, together with clinical course and treatment approaches. Both patients belong to different nationalities, who immigrated a couple of months before their application to our hospital. They applied with similar histories and complaints and were not vaccinated during infancy.

CONCLUSION

With the development of vaccination programs, this disease with high morbidity and mortality can be prevented.

Treatment of severe leptospirosis with therapeutic plasma exchange in a pediatric patient

Ekinci F, Yıldızdaş RD, Horoz ÖÖ, Alabaz D, Tolunay İ, Petmezci E. Treatment of severe leptospirosis with therapeutic plasma exchange in a pediatric patient. Turk J Pediatr 2018; 60: 566-570. Leptospirosis is a common zoonotic disease caused by spirochetes of the genus Leptospira. Although it is mostly a tropical disease, some case reports have been published from temperate regions of the world. The disease presents with a wide spectrum; from asymptomatic self limited disease to a fatal illness characterized by multi-organ involvement. An 8-year-old girl presented with a 5-day history of fever, myalgia, fatigue, vomiting and diarrhea. She developed anuria, hypotension and became unconscious one day after admission and was referred to our pediatric intensive care unit for further evaluation and treatment. Initial physical examination revealed fever, jaundice, diffuse petecchiae on whole body, hepatomegaly and severe hypotension. Laboratory investigations showed elevated liver enzymes and bilirubin levels, elevated creatinine and creatine kinase levels and trombocytopenia. The diagnosis of Leptospirosis was detected by rapid IgM test and confirmed by microscopic agglutination test later. She was treated with mechanical ventilation, wide spectrum antibiotics, positive inotropic agents and penicillin G plus two days of continuous renal replacement therapy and five sessions of therapeutic plasma exchange performed daily. She recovered completely and was transferred to the pediatric ward on the 14th day of hospitalization. The exact role of therapeutic plasma exchange has not been well documented yet, it seems to have benefical effects on clinical and laboratory findings and survival as we observed in our patient and learned from experiences in adult patients presented as case reports.

Assessment of the place of tubular reabsorption of phosphorus in the diagnosis of osteopenia of prematurity

AIM

In this study, we aimed to investigate the utility of tubular reabsorption of phosphorus in the diagnosis of osteopenia of prematurity in addition to biochemical markers.

MATERIALS AND METHOD

Premature babies with a gestational age of ≤32 weeks and/or a birth weight of ≤1 500 g who were hospitalized in the neonatal intensive care unit between June 2009 and March 2011 were included in the study. These babies were evaluated at the 40th gestational week and serum calcium, phosphorus, alkaline phosphatase, urea, creatinine, urinary calcium and phosphorus levels were measured and tubular reabsorption of phosphorus was determined. The subjects who had bone graphy findings and/or an alkaline phosphatase level of >400IU/L and a phosphorus value of <3.5 mg/dL were considered osteopenic. The levels of tubular reabsorption of phosphorus of the osteopenic patients were compared with the ones of the non-osteopenic patients. The study was initiated after obtaining ethics committee approval (date: 04.29.2009/213).

RESULTS

During the study period, a total of 698 premature babies were hospitalized in our neonatology unit. A diagnosis of osteopenia of prematurity was made in 24 of 190 subjects who met the study criteria. The level of tubular reabsorption of phosphorus was compared with the serum calcium, phosphorus and alkaline phosphatase levels measured at the 40th gestational week and alkaline phosphatase was found to be significantly increased in the group with a high tubular reabsorption of phosphorus (≥%95). When the subjects with a phosphorus level of <3.5 mg/dL and an alkaline phosphatase level of >499 IU were compared with the newborns who were found to have a tubular reabsorption of phosphorus of ≥%95 for the objective of evaluating the specificity and sensitivity of tubular reabsorption of phosphorus, the sensitivity, specificity, positive predictive value and negative predictive value of tubular reabsorption of phosphorus in the diagnosis of osteopenia were found to be 27%, 82%, 17% and 89%, respectively. When the osteopenic and non-osteopenic patients were compared in terms of the levels of tubular reabsorption of phosphorus, no statistically significant difference was found.

CONCLUSIONS

It was thought that it was not appropriate to use tubular reabsorption of phosphorus alone in the diagnosis of osteopenia of prematurity.
