RESUMO

Phoneutrism (bites by wandering spiders of the genus Phoneutria) frequently results in local pain. We describe a retrospective cohort study of a case series of phoneutrism admitted to our Emergency Department (ED), in which we used the Numeric Pain Rating Scale (NPRS 0-10) to assess the intensity of local pain upon admission, and recorded the analgesic measures used to control this pain. Other criteria for inclusion were: (1) An age ≥8 years, (2) Treatment exclusively at our ED, and (3) Visualization or photographing the spider at the time of the bite and/or bringing the spider for identification. The patients were classified into three groups based on the intensity of pain at admission: group 1 - mild or no pain (NPRS: 0-3), group 2 - moderate pain (NPRS: 4-6), and group 3 - intense or severe pain (NPRS: 7-10). Fifty-two patients fulfilled the inclusion criteria (n = 11, 14 and 27 in groups 1, 2, and 3, respectively), with a median age of 37 years. The median NPRS upon admission was 7 (interquartile range: 5-8). In patients with an NPRS <7 (groups 1 and 2), only dipyrone was used to alleviate the pain, with six cases in group 1 requiring no analgesia. Most of the cases in group 3 (19/27) were treated with a local anesthetic infiltration (2% lidocaine), in association with analgesics given i.v. in 16 cases (dipyrone, 14; tramadol, 2); additional analgesic treatment was required in seven cases, six of which were treated with tramadol i.v. The median time spent in the ED was 18, 58 and 120 min for groups 1, 2 and 3, respectively. These findings show that most cases of envenoming by Phoneturia spp. involved intense local pain (NPRS ≥7), with local anesthetics being used only in these cases, often in association with dipyrone i.v.

RESUMO

BACKGROUND: Although loxoscelism (bites by brown spiders of the genus Loxosceles) frequently results in dermonecrosis, no previous clinical reports have provided detailed temporal photodocumentation of the evolution of dermonecrotic lesions in a case series. METHODS: This was a retrospective cohort study involving a case series of loxoscelism. Only cases of dermonecrosis with photodocumentation of lesion evolution (from admission until complete or almost complete healing) were included. RESULTS: Eight patients (six men, two women; median age, 38 years) fulfilled the inclusion criteria. The bite sites included the thigh (n = 4), forearm (n = 2), abdomen (n = 1), and trunk (n = 1). Time interval between the bite and first contact with our service ranged from 15 to 216 h (median = 29 h). The main clinical manifestations included local erythematous and ischemic violaceous lesions overlying a base of indurated edema (livedoid plaque, 8), local pain (8), exanthema (6), serohemorrhagic vesicles/blisters (5), fever (5), and jaundice (1). Based on a previously established classification, the cases were classified as probable cutaneous-necrotic loxoscelism (CNL, n = 4), presumptive CNL (n = 3), and presumptive cutaneous-hemolytic loxoscelism (n = 1). Seven patients were treated with anti-arachnidic antivenom (AV; median time post-bite = 46 h). Complete lesion healing ranged from 34 to 98 days post-bite (median, 68 days; six patients). None of the patients required reconstructive plastic surgery. CONCLUSIONS: The sequential photographic documentation showed considerable variation in the process of wound healing, with complete epithelialization requiring up to 3 months after the bite.

RESUMO

OBJECTIVE: To describe a case series of severe acute toxic exposures (SATE) in individuals <20 years old followed-up by a regional Poison Control Center (PCC). METHODS: Descriptive cross-sectional study. All patients who were <20yo and classified as score 3 (severe) and 4 (fatal) following Poisoning Severity Score were included for analysis. According to the outcome, patients were classified as PSS 3 when they developed intense clinical manifestations with risk of death or important sequelae; and as PSS 4 when death had resulted from direct cause or complication of the initial exposure. The data of patients were obtained from the Brazilian electronic database system (DATATOX). RESULTS: During the biennium 2014-2015, Campinas PCC followed up 5,095 patients <20yo, with 30 being classified as SATE (PSS=3, n=24; PSS=4, n=6). The exposures circumstances were unintentional (15); intentional (14; suicide attempt = 11; street drugs consumption = 3); and not explained (1). The exposures were significantly more frequent in adolescents >14yo (n=17; p<0.01). The involved agents were venomous animals (8; scorpions=5); medicines (8; miscellaneous=6); chemicals (6); illegal rodenticides containing acetylcholinesterase inhibitors (chumbinho, 4); drugs of abuse (3); button battery (1). Three patients evolved with sequels (esophageal stricture post-corrosive ingestion). The median length of hospital stay was 6 days (IQR: 5-12 days); 26 patients were treated in intensive care units, and 22 of them needed mechanical ventilation; 12, inotropic/vasopressors; and 3, renal replacement therapy. CONCLUSIONS: Scorpion stings and poisonings caused by medicines and chemicals were the main causes of SATE. The SATE were significantly more frequent in adolescents, due to deliberate self-poisoning.

RESUMO Objetivo: Descrever uma série de casos de exposições tóxicas agudas graves (ETAG) em pacientes <20 anos seguidos por um Centro de Informação e Assistência Toxicológica (CIATox) regional. Métodos: Estudo descritivo de corte transversal. Incluídos no estudo todos os casos classificados como escore 3 (graves) e 4 (fatais) de acordo com o escore de gravidade de intoxicações (poisoning severity score - PSS). Segundo o PSS, os casos são classificados em relação ao desfecho como escore 3 quando os pacientes desenvolveram manifestações clínicas intensas, com risco de morte ou que resultaram em sequelas importantes; e escore 4 quando a morte foi resultado de causa direta ou por complicação da exposição. Os dados analisados foram obtidos da base eletrônica brasileira do Sistema Nacional de Informações Tóxico-Farmacológicas DATATOX. Resultados: No biênio 2014-2015 o CIATox de Campinas atendeu 5.095 casos de pacientes <20 anos, dos quais 30 foram classificados como ETAG (PSS=3, n=24; PSS=4, n=6). Quanto à circunstância, 15 foram acidentais, 14 intencionais (11 por tentativas de suicídio e três por abuso de drogas) e um de causa não esclarecida, sendo significativamente mais frequentes nos adolescentes >14 anos (n=17; p<0,01). Os grupos de agentes envolvidos foram: animais peçonhentos (8; escorpiões=5); medicamentos (8; associações=6); produtos químicos de uso domiciliar/industrial (6); rodenticidas inibidores da colinesterase de uso ilegal (chumbinho=4); drogas de abuso (3); e bateria no formato de disco (1). Três pacientes evoluíram com sequelas (estenose esofágica pós-ingestão de corrosivos). O tempo mediano de internação foi de seis dias (mediana, quartis e intervalo interquartil=5-12 dias), sendo 26 pacientes admitidos em unidades de cuidados intensivos, dos quais 22 necessitaram de ventilação mecânica, 12 de inotrópicos/vasopressores e três de terapia de substituição renal. Conclusões: Escorpionismo e intoxicações por medicamentos e por produtos químicos de uso domiciliar/industrial foram as principais causas de ETAG, sendo elas significativamente mais frequentes em adolescentes, principalmente por tentativas de suicídio.

RESUMO

Abstract Objectives: Human immunodeficiency virus infection can result in the early impairment of anthropometric indicators in children and adolescents. However, combined antiretroviral therapy has improved, in addition to the immune response and viral infection, the weight and height development in infected individuals. Therefore, the objective was to evaluate the effect of combined antiretroviral on the growth development of human immunodeficiency virus infected children and adolescents. Source of data: A systematic review was performed. In the study, the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) strategy was used as the eligibility criterion. The MEDLINE-PubMed and LILACS databases were searched using these descriptors: HIV, children, growth, antiretroviral therapy. The objective was defined by the population, intervention, comparison/control, and outcome (PICO) technique. Inclusion and exclusion criteria were applied for study selection. Synthesis of data: Of the 549 studies indexed in MEDLINE-PubMed and LILACS, 73 were read in full, and 44 were included in the review (33 showed a positive impact of combined antiretroviral therapy on weight/height development, ten on weight gain, and one on height gain in children and adolescents infected with human immunodeficiency virus). However, the increase in growth was not enough to normalize the height of infected children when compared to children of the same age and gender without human immunodeficiency virus infection. Conclusions: Combined antiretroviral therapy, which is known to play a role in the improvement of viral and immunological markers, may influence in the weight and height development in children infected with human immunodeficiency virus. The earlier the infection diagnosis and, concomitantly, of malnutrition and the start of combined antiretroviral therapy, the lower the growth impairment when compared to healthy children.


Resumo Objetivos: A infecção pelo vírus da imunodeficiência humana pode comprometer, precocemente, os indicadores antropométricos de crianças e adolescentes. No entanto, a terapia antirretroviral combinada tem melhorado, além da resposta imunológica e da infecção viral, o ganho pôndero-estatural dos infectados. Dessa forma, nosso objetivo foi avaliar o efeito da terapia antirretroviral combinada no crescimento, de crianças e adolescentes, infectadas pelo vírus da imunodeficiência humana. Fonte dos dados: Foi realizada uma revisão sistemática. No estudo, adotou-se como critério de elegibilidade dos artigos, a estratégia PRISMA (preferred reporting items for systematic reviews and meta-analyses). Foram consultadas as bases de dados MEDLINE-PubMed e LILACS pelos descritores: HIV (vírus da imunodeficiência humana), children, growth, antiretroviral therapy. O objetivo foi definido pela estratégia PICO (population, intervention, comparison/control, outcome). Critérios de inclusão e exclusão foram aplicados na seleção dos estudos. Síntese dos dados: Dos 549 estudos indexados no MEDLINE-PubMed e LILACS, 73 foram lidos na íntegra - 44 incluídos na revisão (33 demonstraram impacto positivo da terapia antirretroviral combinada no ganho pôndero-estatural, dez no ganho de peso e um no de estatura, em crianças e adolescentes, infectados com vírus da imunodeficiência humana). No entanto, o incremento no crescimento não foi o suficiente para normalizar a estatura de crianças infectadas, quando comparado com crianças da mesma idade e sexo, sem infecção pelo vírus da imunodeficiência humana. Conclusões: A terapia antirretroviral combinada que, conhecidamente, atua na melhora de marcadores virais e imunológicos, pode influenciar no ganho pôndero-estatural de crianças infectadas com vírus da imunodeficiência humana. Quanto mais precoce o diagnóstico da infecção e, concomitante, desnutrição e início da terapia antirretroviral combinada, menores serão os prejuízos no crescimento, quando comparado às crianças saudáveis.

RESUMO

CONTEXT: Thrombotic microangiopathy (TMA) is an uncommon and severe complication of snakebites, and is similar, in general, to hemolytic-uremic syndrome (HUS). We describe a case of TMA following envenomation by Bothrops jararaca. CASE DETAILS: A 56-y-old-woman with controlled hypertension was transferred from a primary hospital to our ER ∼7 h after being bitten by B. jararaca in the distal left leg. She developed edema extending from the bite site to the proximal thigh, associated with intense radiating local pain, local paresthesia and ecchymosis at the bite site. Laboratory features upon admission revealed coagulopathy (20 min whole blood clotting time - WBCT20 > 20 min), thrombocytopenia (76,000 platelets/mm3) and slight increase in serum creatinine (1.58 mg/dL; RV < 1.2 mg/dL). Upon admission, the patient was treated with bothropic antivenom and fluids replacement. During evolution, her thrombocytopenia and anemia worsened, with blood films showing fragmented red cells, haptoglobin consumption, increase in serum lactate dehydrogenase, and progressive increase of serum creatinine (KDIGO stage = 3). No RBC transfusion, renal replacement therapy or plasmapheresis was done. The patient showed progressive improvement from day nine (D9) onwards and was discharged on D20; there was complete recovery of hemoglobin levels at follow-up (D50). ADAMTS-13 activity, assayed 10 months post-bite, was within reference values. DISCUSSION: TMA following snakebite has been reported mainly in India, Sri Lanka and Australia, with several patients needing renal replacement therapy. Although controversial, plasmapheresis has also been used in some cases. Our patient developed microangiopathic hemolytic anemia, thrombocytopenia and acute kidney injury, a triad of features compatible with TMA similar to HUS. Despite the severity, the outcome following conservative treatment was good, with complete recovery.

RESUMO

CONTEXT: Erucism, envenomation caused by dermal contact with larval forms of moths, may result in intense local pain, mainly after contact with puss caterpillars (family Megalopygidae). OBJECTIVE: To evaluate the response to different treatments for controlling severe pain in a case series of erucism in Campinas, southeastern Brazil. PATIENTS AND METHODS: Prospective cohort study. A Numeric Pain Rating Scale (NPRS 0-10) was used to assess pain intensity in the Emergency Department (ED). Pain was considered as severe upon ED admission (T0) when the NPRS was ≥8. INCLUSION CRITERIA: age ≥8 years old, severe pain at T0, with continuous assessment of pain intensity in all patients using the NPRS during the ED stay (T5, T15, T30, T60 min and at discharge). RESULTS: Fifty-five patients fulfilled the inclusion criteria and were divided into three groups according to the initial treatment at T0: local anesthesia alone with 2% lidocaine (group 1, n = 15), local anesthesia and analgesics (group 2, n = 26) and analgesics without local anesthesia (group 3, n = 14). Most patients were admitted within 2 h after dermal contact with the stinging bristles of caterpillars (median =90 min, IQR: 40-125 min). In 22 cases (40%), the caterpillar was brought for identification (Podalia spp., n = 18; Megalopyge spp., n = 4). There was a significant decrease in pain from T5 onwards with all of the treatments. When the short-term response (T5 and T15) was considered, analgesia was more effective in groups 1 and 2 compared to group 3 (p < .01). Additional analgesia (from T5 until discharge) was frequently required (n = 25/55), mainly in group 1 (n = 11/15). The median length of stay in the ED was 120 min (IQR: 80-173 min). CONCLUSIONS: The association of local anesthesia with analgesics was apparently a good combination for the rapid management of severe pain in the ED.

RESUMO

CONTEXT: Acetonitrile (ACN) is a solvent rapidly absorbed through lungs and intestinal tract, and is slowly metabolized to cyanide (CN) by enzymatic processes mediated by CYP2E1. OBJECTIVE: To describe the clinical and laboratory evolution, ACN elimination half-life, and its presence in breast milk in a nursing mother who attempted suicide. CASE DETAILS: A 25-year-old 2-month nursing mother ingested an estimated dose of 2.1 g/kg of ACN. Blood and urine samples were collected 24 h later for ACN, CN and thiocyanate analysis, and 12.5 g sodium thiosulfate i.v. in 1-h infusion was started and repeated every 24 h for 4 days. ACN results showed 200 mg/L in blood and 235 mg/L in urine. ACN analysis in the breast milk at Day 6 showed level of 21 mg/L compared to 27 mg/L in blood collected at the same time, suggesting a possible relationship of 1.3:1.0 ratio. An elimination half-life of 40.4 h was calculated, compared to 32 and 36 h showed in other studies. DISCUSSION: The clinical management must involve the use of CN antidotes for more than 24 h depending on the symptoms and blood levels of ACN. Furthermore, our data showed the possible existence of a close relationship between plasma and breast milk levels.

RESUMO

JUSTIFICATIVA E OBJETIVOS: Relatar um caso clínico de erro de administração de solução de clister glicerinado por via venosa. RELATO DO CASO: Paciente do sexo masculino, 56 anos, procurou hospital por queixa de dor abdominal e constipação há 5 dias. Possuía antecedente de hipertensão mal controlada sem outras alterações de exame físico. Foi prescrito clister glicerinado (500 mL a 12%) que, erroneamente, foi administrado por via venosa (T0). O erro quando detectado, foi comunicado ao Centro de Controle de Intoxicações de Campinas, que orientou iniciari nvestigação laboratorial, revelando inicialmente hematúria microscópica discreta, elevação de CK (401 U/L; VR= 26-189),e níveis aumentados de ureia (66 mg/dL; VR = 15-40) e creatinina (2,4 mg/dL; VR = 0,7-1,4). A dosagem de bilirrubina total encontrava-se elevada (1,8 mg/dL; VR até 1,2) às custas de BI =1,7 mg/dL (VR = 0,1-0,8). Durante a evolução, o eritrograma mostrou discreta redução dos níveis de hemoglobina (Hb) (14,6 g/dL [T2] e 13,8 g/dL [T5:30]) e paciente apresentou leucocitose (18.200) sem desvio. Transferido ao hospital de referênciano T15:30, onde os exames laboratoriais demonstravam dosagem sérica de bilirrubina total dentro do VR (0,75 mg/dL), Hb = 14 g/dL e CK mantinham-se elevadas (625 U/L). Durante toda a internação o paciente permaneceu assintomático. CONCLUSÃO: Apesar da escassez de informações sobre o glicerol administrado por via venosa ter suscitado preocupação com relação a possíveis efeitos tóxicos, o desfecho favorável deste caso, em concordância com a literatura, sugeriu que a infusão de solução de clister glicerinado disponível comercialmente (12%), até a dose de 0,65 g/kg, não parece implicar em riscos elevados de efeitos adversos.


BACKGROUND AND OBJECTIVES: To report a clinical case of iatrogenic administration of glycerol rectal preparation intravenously (IV). CASE REPORT : Male patient, 56 years, searched for hospital complaining of abdominal pain and constipation for 5 days. Hehad a history of arterial hypertension poorly controlled. For the constipation, glycerin (500 mL to 12%) was prescribed, which mistakenly was given IV (T0). The error was reported to the Campinas Poison Control Center, which advised to monitor electrolyte and metabolic changes. Patient presented mild microscopic hematuria, elevated CK (401 U/L; RV = 26-189), and increased levels of urea (66 mg/dL; VR = 15-40) and creatinine (2.4 mg /dL, RV = 0.7-1.4). The level of total bilirubin was elevated (1.8mg / dL, RV = up to 1.2) due to unconjugated =1.7 mg/dL (RV = 0.1-0.8). During evolution, showed the erythrocyte slight reductionof Hb levels (14.6 g/dL [T2] and 13.8 g/dL [T5: 30]) and patient showed leukocytosis (18,200) (T5:30). Transferred to reference hospital at T15: 30, where tests showed serum total bilirubin within the VR (0.75 mg/dL), Hb = 14 g/dL and CK remained high (625 U/L). During hospitalization the patient remained asymptomatic. CONCLUSION : Despite the paucity of information about effects of glycerol IV, this case has raised concern about possible toxic effects, due to volume and concentration of glycerol administered.The favorable outcome, rather in agreement with thel iterature, has suggested that the IV infusion of commercially available glycerin enema solution (12%) does not seem to beof significant risk to the patient.

RESUMO

BACKGROUD: Chronic liver diseases in childhood often cause undernutrition and growth failure. To our knowledge, growth parameters in infants with neonatal cholestasis are not available AIM: To evaluate the nutritional status and growth pattern in infants with intrahepatic cholestasis and extrahepatic cholestasis. PATIENTS AND METHODS: One hundred forty-four patients with neonatal cholestasis were followed up at the Pediatric Gastroenterology Service of the Teaching Hospital, State University of Campinas, Campinas, SP, Brazil, in a 23-year period, from 1980 to 2003. The records of these patients were reviewed and patients were classified into two groups, according to their anatomical diagnosis: patients with intrahepatic cholestasis - group 1, and patients with extrahepatic cholestasis - group 2. Records of weight and height measurements were collected at 4 age stages of growth, in the first year of life: 1) from the time of the first medical visit to the age of 4 months (T1); 2) from the 5th to the 7th month (T2); 3) from the 8th to the 10th month (T3); and 4) from the 11th to the 13th month (T4). The weight-by-age and height-by-age Z-scores were calculated for each patient at each stage. In order for the patient to be included in the study it was necessary to have the weight and/or height measurements at the 4 stages. Analyses of variance and Tukey's tests were used for statistical analysis. Repeated measurement analyses of variance of the weight-by-age Z-score were performed in a 60-patient sample, including 29 patients from group 1 and 31 patients from group 2. The height-by-age data of 33 patients were recorded, 15 from group 1 and 18 from group 2 RESULTS: The mean weight-by-age Z-scores of group 1 patients at the 4 age stages were: T1=-1.54; T2=-1.40; T3=-0.94; T4=-0.78. There was a significant difference between T2 X T3 and T1 X T4. The weight-by-age Z-scores for group 2 patients were :T1=-1.04; T2=-1.67; T3=-1.93 and T4=-1.77, with a...


RACIONAL: As doenças hepáticas crônicas na infância freqüentemente levam à desnutrição e ao déficit de crescimento, sem haver referência de um padrão definido para colestase neonatal OBJETIVO: Avaliar o estado nutricional e o padrão de crescimento em crianças com colestase intra-hepática e colestase extra-hepática MATERIAL E MÉTODOS: Foram revistos os prontuários de 144 pacientes com colestase neonatal atendidos no Serviço de Gastroenterologia Pediátrica do Hospital de Clínicas da UNICAMP, Campinas, SP, durante o período de 1980 a 2003 e de acordo com o diagnóstico anatômico, classificados em dois grupos: grupo 1, pacientes com colestase intra-hepática e grupo 2, com colestase extra-hepática. Os valores de peso e estatura foram obtidos em quatro momentos: 1°) Na primeira consulta realizada até o 4° mês de vida, 2°) entre o 5° e o 7° mês, 3°) entre o 8° e o 10° mês e 4°) entre o 11° e 13° mês. Para cada paciente foi realizado o cálculo do Z-escore em relação ao peso para a idade e estatura para a idade nos momentos 1 a 4. Para o paciente ser incluído no estudo, era necessário ter as medidas de peso e/ou estatura nos quatro estágios. A estatística empregada foi a análise de variância e o teste de Tukey. Para análise de variância com medidas repetidas quanto ao escore-Z de peso para a idade, a amostra utilizada foi de 60 pacientes, sendo 29 do grupo 1 e 31 do grupo 2. Para estatura, a amostra utilizada foi de 33 pacientes, sendo 15 do grupo 1 e 18 do grupo 2. RESULTADOS: As médias dos escores-Z de peso para a idade nos quatro momentos da avaliação para os pacientes do grupo 1 foram: T1 =-1.54; T2 = -1.40; T3 = -0,94; T4 = -0.78, havendo diferença significante entre T2×T3 e entre T1×T4. Para os pacientes do grupo 2 foram: T1 = -1.04; T2 = -1.67; T3 =-1.93 e T4 = -1.77, havendo diferença significante entre T1×T2 e T1×T4. Houve também diferença significante entre as médias dos escores-Z de peso para a idade entre o grupo...

RESUMO

BACKGROUND: [corrected] Chronic liver diseases in childhood often cause undernutrition and growth failure. To our knowledge, growth parameters in infants with neonatal cholestasis are not available AIM: To evaluate the nutritional status and growth pattern in infants with intrahepatic cholestasis and extrahepatic cholestasis. PATIENTS AND METHODS: One hundred forty-four patients with neonatal cholestasis were followed up at the Pediatric Gastroenterology Service of the Teaching Hospital, State University of Campinas, Campinas, SP, Brazil, in a 23-year period, from 1980 to 2003. The records of these patients were reviewed and patients were classified into two groups, according to their anatomical diagnosis: patients with intrahepatic cholestasis - group 1, and patients with extrahepatic cholestasis - group 2. Records of weight and height measurements were collected at 4 age stages of growth, in the first year of life: 1) from the time of the first medical visit to the age of 4 months (T1); 2) from the 5th to the 7th month (T2); 3) from the 8th to the 10th month (T3); and 4) from the 11th to the 13th month (T4). The weight-by-age and height-by-age Z-scores were calculated for each patient at each stage. In order for the patient to be included in the study it was necessary to have the weight and/or height measurements at the 4 stages. Analyses of variance and Tukey's tests were used for statistical analysis. Repeated measurement analyses of variance of the weight-by-age Z-score were performed in a 60-patient sample, including 29 patients from group 1 and 31 patients from group 2. The height-by-age data of 33 patients were recorded, 15 from group 1 and 18 from group 2 RESULTS: The mean weight-by-age Z-scores of group 1 patients at the 4 age stages were: T1=-1.54; T2=-1.40; T3=-0.94; T4=-0.78. There was a significant difference between T2 X T3 and T1 X T4. The weight-by-age Z-scores for group 2 patients were :T1=-1.04; T2=-1.67; T3=-1.93 and T4=-1.77, with a significant difference between T1 X T2 and T1 X T4. The mean weight-by-age Z-scores also showed a significant difference between group 1 and group 2 at stages T3 and T4. The mean height-by-age Z-scores at the four stages in group 1 were: T1=-1.27; T2=-1.16; T3=-0.92 and T4=-0.22, with a significant difference between T3XT4 and T1XT4. The scores for group 2 patients were: T1=-0.93; T2=-1.89; T3=-2.26 and T4=-2.03, with a significant difference between T1XT2 and T1XT4. The mean height-by-age Z-scores also showed a significant difference between group 1 and group 2 at T3 and T4 CONCLUSION: The weight and height differences between the groups became significant from the 3rd measurement onward, with the most substantial deficit found in the extrahepatic group. In this group, there is evidence that the onset of weight and height deficit occurs between the first and second evaluation stages.
