A complex case of abdominal pain in a patient with pelviureteric junction obstruction
Pelviureteric junction (PUJ) obstruction is a condition frequently encountered in both adult and pediatric patients. Congenital abnormalities and crossing lower-pole renal vessels are the most common underlying pathologies in both men and women. This report presents a case of a young woman who was complaining of intermittent abdominal pain in whom right-sided hydronephrosis was diagnosed. The patient was scheduled for a laparoscopic right-sided Anderson-Hynes pyeloplasty. During the procedure a partly extraperitoneal appendix, with extensive adhesions to the posterior abdominal wall abutting on the ureter just below the obstructed PUJ, was identified. The patient underwent dismembered laparoscopic Anderson-Hynes pyeloplasty with concurrent appendectomy for likely dual pathologies being responsible for her symptoms
Management of blunt injury to the spleen in children
W ostatnich latach zmieniła się strategia postępowania w tępych urazach śledziony zarówno u dzieci, jak
i u dorosłych. Powszechnie wykonywaną w tych przypadkach splenektomię zastąpiło leczenie zachowawcze
polegające na ścisłej obserwacji pacjenta. Leczenie operacyjne zarezerwowano dla przypadków
niestabilnych hemodynamicznie, mimo intensywnej resuscytacji płynowej. W tych przypadkach splenektomię
zastąpiło szycie śledziony i umieszczanie jej w siatce dakronowej. W razie niekontrolowanego
krwotoku z jamy brzusznej, przy braku możliwości zaopatrzenia krwawienia, należy rozpatrzyć packing i wtórną
laparotomię po wyrównaniu zaburzeń hemodynamicznych. Usunięcie śledziony zarezerwowano dla uszkodzenia

Diagnosis and treatment of post-traumatic hypothermia in hospitals : a pilot study
Background: An unintentional drop in core body temperature of trauma victims is associated with increased mortality. Thermoregulation is impaired in these patients, especially when treated with opioids or anesthetics. Careful thermal insulation and active warming are necessary to maintain normothermia. The aim of the study was to assess the equipment and procedures for diagnosing and managing post-traumatic hypothermia in Polish hospitals. Methods: Survey forms regarding equipment and procedures on monitoring of core temperature (Tc) and active warming were distributed to every hospital that admits trauma victims in the Holy Cross Province. Questionnaires were addressed to surgery departments, intensive care units (ICUs), and operating rooms (ORs). Results: 92% of surgery departments did not have equipment to measure core body temperature and 85% did not have equipment to rewarm patients. Every ICU had equipment to measure Tc and 83% had active warming devices. In 50% of ICUs, there were no rewarming protocols based on Tc and the initiation of rewarming was left to the physician’s discretion. In 58% of ORs, Tc was not monitored and in 33% the patients were not actively warmed. Conclusions: The majority of surveyed ICUs and ORs are adequately equipped to identify and treat hypothermia, however the criteria for initiating Tc monitoring and rewarming remain unstandardized. Surgery departments are not prepared to manage post-traumatic hypothermia
Połknięcie ciała obcego przez pacjenta pediatrycznego — analiza przypadków oraz wątki prawne
Foreign body ingestion by paediatric patients is a common problem in medical practice. This article aims to analyse the clinical picture, the aetiology and to comment on the legal liability that the caregiver or the manufacturer may incur in such cases. The presented data come from a 3-year period from a medical centre in Kielce and were analysed retrospectively. The study involved 75 children. Educating caregivers to pay more attention to where they place dangerous objects or to buying toys consisting of small parts may contribute to the reduction of the percentage of patients with the described issues.Połknięcie ciała obcego przez pacjentów pediatrycznych stanowi częsty problem w praktyce medycznej. Celem artykułu jest analiza obrazu klinicznego, etiologii i przedstawienie uwag dotyczących odpowiedzialności prawnej, jaką może ponieść w takim przypadku opiekun lub producent. Prezentowane dane pochodzą z placówki medycznej w Kielcach, zbierane w ciągu trzech lat i zostały przeanalizowane w sposób retrospektywny. W badaniu udział wzięło 75 dzieci. Edukacja opiekunów, by większą uwagę przykładali do miejsc odkładania przedmiotów niebezpiecznych czy kupowania zabawek składających się z drobnych części, może się przyczynić do zmniejszenia odsetka pacjentów z opisanymi przypadłościami
The Development of Cortical Responses to the Integration of Audiovisual Speech in Infancy
In adults, the integration of audiovisual speech elicits specific higher (super-additive) or lower (sub-additive) cortical responses when compared to the responses to unisensory stimuli. Although there is evidence that the fronto-temporal network is active during perception of audiovisual speech in infancy, the development of fronto-temporal responses to audiovisual integration remains unknown. In the current study, 5-month-olds and 10-month-olds watched bimodal (audiovisual) and alternating unimodal (auditory + visual) syllables. In this context we use alternating unimodal to denote alternating auditory and visual syllables that are perceived as separate syllables by adults. Using fNIRS we measured responses over large cortical areas including the inferior frontal and superior temporal regions. We identified channels showing different responses to bimodal than alternating unimodal condition and used multivariate pattern analysis (MVPA) to decode patterns of cortical responses to bimodal (audiovisual) and alternating unimodal (auditory + visual) speech. Results showed that in both age groups integration elicits cortical responses consistent with both super- and sub-additive responses in the fronto-temporal cortex. The univariate analyses revealed that between 5 and 10 months spatial distribution of these responses becomes increasingly focal. MVPA correctly classified responses at 5 months, with key input from channels located in the inferior frontal and superior temporal channels of the right hemisphere. However, MVPA classification was not successful at 10 months, suggesting a potential cortical re-organisation of audiovisual speech perception at this age. These results show the complex and non-gradual development of the cortical responses to integration of congruent audiovisual speech in infancy
Laparoscopy in inguinal hernia and complete androgen insensitivity syndrome in children. Whether and when to remove the gonads because of cancer?
Androgen insensitivity syndrome (CAIS) – also called Morris syndrome, formerly known as testicular feminisation syndrome – is a congenital disorder of sex development caused by various mutations in the gene encoding the androgen receptor. Androgen insensitivity syndrome occurs in a complete form (complete androgen insensitivity syndrome – CAIS) or a partial form (partial androgen insensitivity syndrome – PAIS). In approximately 1% (according to various researchers, 0.8–2.4%) of cases of inguinal hernia in girls during the time before menarche, CAIS is seen. The laparoscopic procedure for inguinal hernia repair allows a visual assessment of the gonads, and possibly the collection of specimens from the gonads. This is much simpler, compared to the conventional procedure

Testicular torsion based on material from the Department of Paediatric Surgery, Urology and Traumatology at Wladyslaw Buszkowski Children’s Hospital in Kielce during 2008–2013
Introduction: Among the causes of acute scrotum syndrome, testicular torsion undoubtedly causes the most serious consequences. The remaining aetiological factors are torsion of the testicular appendages and of the epididymis, epididymo-orchitis, testicular injury, incarcerated inguinal hernia, acute testicular hydrocele and idiopathic scrotal oedema. Torsion of the testis occurs as a result of a twisting of the testis around the vertical axis. This leads to venous occlusion and subsequently to arterial occlusion with ischaemia and necrosis of the gonad.
Aim of the research: Determination of the possibilities of saving the testicle after torsion of the gonad.
Material and methods: S ixty-eight cases of testicular torsion were analysed in boys aged 0–18 years who were treated during the period 2008–2013 in the Department of Paediatric Surgery, Urology and Traumatology in Kielce. The evaluation determined whether or not the gonad could be saved. The degree of macroscopically evident testicular necrosis was determined and the decision made concerning the saving or resecting the gonad. Further development of the saved testicle was monitored ambulatorily.
Results: In 39 patients the testicle was removed due to necrosis, while in the remaining cases the gonad was saved. Torsion of the left testicle was more frequently observed. The symptoms of the torsion were: testicle pain, nausea and vomiting and, more rarely, abdominal pain. The symptoms occurred from 2 h to several days before reporting to hospital. Emergency surgery was performed. After the surgery ultrasonographic control covered the assessment of blood flow, echostructure and dimensions of the saved gonad (due to the possibility of atrophy after torsion).
Conclusions: A patient who reports pain in the scrotal region should be approached as an emergency case, requiring immediate diagnostics and, very often, emergency surgical management. USG examination with the assessment of intratesticular vascular flow is a standard additional examination in the differential diagnostics of acute scrotum syndrome. Evaluation of the testicles is a necessary element of physical examination in all boys with abdominal pain
