Amaç: Bu çalışmanın amacı, hipotonik bebeklerin tanı profilini belirlemek ve tanı sürecinde bir algoritmanın gerekliliğini analiz etmektir. Gereç ve Yöntemler: Çalışmaya hipotoni şikayetiyle kabul edilen 53 hasta dahil edildi. Hipotonik bebekler klinik bulgularına göre iki gruba ayrıldı: Santral ve periferik. Klinik verilerin analizi ve araştırmaların sonuçlarıyla altı basamaklı bir algoritma oluşturuldu. Bulgular: Otuz sekiz hastada santral hipotoni ve 15 hastada periferik hipotoni mevcuttu. Santral hipotonili hastalara dikkatli bir anamnez ve fizik muayeneden sonra basit karyotip analizi ve kranial görüntüleme ile %57.8 oranında tanı konulabildi. Nörometabolik hastalıklara daha ileri tetkiklerle tanı konuldu. Birinci basamak (klinik veriler ve fizik muayene) ve 2. basamak (kranial BT, MRI) 21 hastanın tanısını çözdü. Üçüncü basamakta (dismorfik bulgularla literatür taraması) ve dördüncü basamak (karyotip analizi) sonunda 6 hastanın tanı alması sağlandı. Beşinci basamakta biyokimyasal testlerle hastaların % 15’ine tanı konuldu. Altıncı basamaktaki testler (CK, EMG, SMA ve KMD için DNA analizi, kas biopsisi) 7 hasta için tanı koydurucuydu. Kalan dokuz hastaya tanı konulamadı. Sonuç: Hipotonik infantların sistemik değerlendirilmesinde gereksiz tanı koydurucu işlemlerin yapılmasını önlemek amacıyla bir algoritmanın kullanılması yararlı olacaktır.
Objective: The aim of this study was to determine the diagnostic profile of infants with hypotonia and to analyze the necessity of an algorithm in the diagnostic process.Material and Methods: Fifty-three patients admitted with the complaint of hypotonia were included in the study. The hypotonic infants were divided into two groups: central and peripheral hypotonia. An algorithm containing six steps was constructed with the analysis of clinical data and results of investigations. Results: Thirty-eight infants had central hypotonia and 15 had peripheral hypotonia. Through a careful medical history and physical examination, a diagnosis was made in 57.8% of the patients with hypotonia by a simple karyotype analysis and cranial MRI. The neurometabolic diseases were diagnosed with further investigations. Step 1 (clinical data and physical examination) and Step 2 (cranial CT, MRI) provided the diagnosis of 21 patients. Step 3 (literature search with dysmorphic findings) and Step 4 (karyotype analysis) contributed to the diagnosis of 6 patients. The diagnosis required biochemical tests in Step 5 in 15 percent of the patients. The Step 6 tests (CK, EMG, DNA analysis for SMA and CMD, muscle biopsy) were diagnostic for 7 patients. The remaining nine patients could not be diagnosed. Conclusion: An algorithm would be useful for the systematic evaluation of hypotonic infants to prevent unnecessary diagnostic procedures

The publication language of Turkish Journal of Pediatric Disease is English.
Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 10 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.
The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
