Multi-institutional analysis of cervical esophageal carcinoma patients treated with definitive chemoradiotherapy: TROD 01-005 study

The aim of this study was to examine the prognostic factors and treatment outcomes of cervical esophageal carcinoma (CEC) patients who underwent definitive chemoradiotherapy (CRT). The clinical data of 175 biopsy-confirmed CEC patients treated with definitive CRT between April 2005 and September 2021 were retrospectively analyzed. The prognostic factors predicting overall survival (OS), progression-free survival (PFS), and local recurrence-free survival (LRFS) were assessed in uni- and multivariable analyses. The median age of the entire cohort was 56 years (range: 26–87 years). All patients received definitive radiotherapy with a median total dose of 60 Gy, and 52% of the patients received cisplatin-based concurrent chemotherapy. The 2-year OS, PFS, and LRFS rates were 58.8%, 46.9%, and 52.4%, respectively, with a median follow-up duration of 41.6 months. Patients’ performance status, clinical nodal stage, tumor size, and treatment response were significant prognostic factors for OS, PFS, and LRFS in univariate analysis. Non-complete treatment response was an independent predictor for poor OS (HR = 4.41, 95% CI, 2.78–7.00, p < 0.001) and PFS (HR = 4.28, 95% CI, 2.79–6.58, p < 0.001), whereas poor performance score was a predictor for worse LRFS (HR = 1.83, 95% CI, 1.12–2.98, p = 0.02) in multivariable analysis. Fifty-two patients (29.7%) experienced grade II or higher toxicity. In this multicenter study, we demonstrated that definitive CRT is a safe and effective treatment for patients with CEC. Higher radiation doses were found to have no effect on treatment outcomes, but a better response to treatment and a better patient performance status did.     

Proliferative activity, angiogenesis and nuclear morphometry in renal cell carcinoma

BACKGROUND: Prognostic parameters other than tumor stage and grade are essential for renal cell carcinoma (RCC) patients. This study was undertaken to determine the usefulness of cellular proliferation, angiogenesis and nuclear morphometry in predicting the biological aggressiveness of RCC. METHODS: Surgical specimens of 70 patients with RCC were investigated by conventional histology, Ki-67 immunostaining and stereological assessment of angiogenesis and mean nuclear volume. RESULTS: There was no difference in disease-specific survival with respect to sex, age and histopathological type (except sarcomatoid and other types). The survival was significantly lower and the chance of metastases was higher in the group with higher proliferative activity (P=0.007). There was no relation between angiogenesis, mean nuclear volume, stage and survival. There was a significant relation between both Fuhrman and WHO grades, tumor stage and survival. Histopathological type, grade, angiogenesis and mean nuclear volume failed to predict recurrences and/or metastases. In multivariate analysis, only TNM stage and proliferative activity were found to be independent prognostic factors. CONCLUSIONS: In addition to tumor grade and stage, proliferative activity of a given RCC may have the potential to identify patients with an impaired prognosis.     

Medico-legal child deaths in Istanbul: data from the Morgue Department

BACKGROUND: Before determining health policies, finding solutions to problems and taking precautions, one should define the problems and their regional and national dimensions. Data about causes of death vary from country to country and, therefore, it is clear that precautions should be based on regional data and needs, which will be more effective. METHOD: The authors reviewed deaths among children aged 1 month to 18 years, whose autopsies were performed in the Morgue Department, State Institute of Forensic Medicine, Istanbul, Turkey, between 2000 and 2002. RESULTS: The authors evaluated autopsy reports about 736 child deaths. The mean age of the children was 8.77 +/- 6.25 years and 62.8% of the children were male. As to causes of death, the most frequent was asphyxia. Almost half of them were caused by mechanical asphyxia due to drowning. A total of 48.5% of the deaths were accidental. There was a significant difference in causes of death between children aged 11 years or younger and those aged over 11 years. Death due to nontraumatic conditions and poisoning was predominant among children aged 11 years and younger, while death due to gunshot wounds and stab wounds was predominant among children aged more than 11 years. There was a significant difference in causes of death between females and males. CONCLUSION: Asphyxia, poisoning and blunt traumatic injuries were found to be the leading causes of death, which can be prevented or decreased by certain precautions. As a result, new regulations should be enacted to protect children against accidents, injuries and hazards and a child protection program is needed in Turkey.     

Focal cerebral vasculitis and stroke after chickenpox

Cerebral infarcts are rather rare in children and can be caused by a number of diverse conditions. We report a case of cerebral infarct associated with a recent varicella infection. A 5-year old girl presented with an acute central facial palsy 1 month after a chickenpox infection. The infarction was revealed by magnetic resonance imaging and laboratory studies ruled out all known causes of stroke. Cerebral angiogram demonstrated segmental narrowing and irregularity of the wall of the right internal carotid artery, compatible with focal vasculitis. With the presumed diagnosis of varicella-associated focal angiitis, the patient was treated with high-dose methylprednisolone, acyclovir and aspirin. Magnetic resonance angiogram performed 6 weeks after the stroke demonstrated the resolution of the vasculitis. Varicella infection should be considered one of the possible causes of acute ischaemic strokes in children.     

Long‐term prognosis of nonalcoholic fatty liver disease: Is pharmacological therapy actually necessary?

Background and Aim: Nonalcoholic fatty liver disease (NAFLD) comprises a wide spectrum of liver injury, ranging from steatosis and steatohepatitis to cirrhosis. Reasons for the different natural course in individuals with NAFLD are still unclear. The aim of this study was to describe the natural course of disease in individuals with NAFLD who did not receive pharmacological therapy. Methods: A total of 27 individuals with NAFLD (male/female ratio: 10/17, mean age 49.7 years) were prospectively enrolled. Management after diagnosis consisted of establishment of an appropriate diet and exercise (walking and jogging) program, treatment of associated metabolic conditions such as diabetes and dyslipidemia, and discontinuation of potentially hepatotoxic drugs if the patient was taking these. Liver tests were performed at diagnosis and at 3‐month intervals during the follow‐up period. Mean follow‐up period was 43.3 months (range 36–49 months). Results: From baseline to the end of the follow‐up period, although there was no significant difference observed in terms of the mean body mass index, serum aminotransferase levels significantly improved (48.8 ± 29.9 U/L to 31.6 ± 16.0 U/L for aspartate aminotransferase [AST] and 66.3 ± 38.3 U/L to 39.6 ± 22.9 U/L for alanine aminotransferase [ALT]; P < 0.05). No significant differences in platelet counts, serum albumin level or prothrombin time were observed (P > 0.05). No patient developed signs of advanced liver disease during the follow‐up period. Conclusion: A treatment strategy comprising diet, exercise and management of associated metabolic conditions is associated with improvement in aminotransferases among patients with NAFLD. Further investigation is needed to examine the long‐term efficacy of this approach on liver histology and clinical outcomes.     

Hidradenitis Suppurativa: Importance of Early Treatment; Efficient Treatment with Electrosurgery

BACKGROUND Hidradenitis suppurativa is a challenging condition, both for the physicians and for the patients. Many surgical and medical approaches with different success rates have been undertaken. Early and appropriate intervention is a factor that significantly increases the success rate of the treatment of the disease.
OBJECTIVE This study was conducted to evaluate the efficiency of electrosurgery treatment in early hidradenitis suppurativa.
MATERIALS AND METHODS This study comprised 12 patients aged between 29 and 38 years (mean, 34 years) with a diagnosis of hidradenitis suppurativa Grade I ( n =9) or Grade II ( n =3). A surgical method consisted of excision of the areas with nodules and sinuses, up to the level of subcutaneous fat tissue, and leaving the surgical defect for secondary healing.
RESULTS All patients completed the study. In 10 of 12 (83%) patients, 26 of 30 (86%) lesions, cure was observed in a mean of 16 days (range 15 to 21 days). Four lesions in 2 patients with Grade II became infected and required a short course of antibiotic therapy.
CONCLUSION Electrosurgery will decrease the need for other systemic treatments, owing to its high cure rates. Our results showed that electrosurgery should be considered a top alternative in the treatment algorithm of hidradenitis suppurativa.     

Hypernatremic dehydration in the newborn period and long-term follow up

BACKGROUND: Hypernatremic dehydration due to inadequate fluid intake can be a significant problem during the neonatal period and thereafter. The objective of the present study was to evaluate the term newborn infants admitted to Gazi University Hospital neonatal intensive care unit (NICU) for hypernatremic dehydration between June 2001 and June 2003 and compare the results with those of the literature search performed via MEDLINE for infants with the same diagnosis. METHODS: Infants with weight loss > or =10% were evaluated for hypernatremia and the ones with serum Na level > or =150 mEq/L were admitted to NICU. Long-term follow-up evaluations were performed using Bayley Scales of Infant Development I (BSID I) and Bayley Infant Neurodevelopmental Screener (BINS) tests. RESULTS: Between June 2001 and June 2003, 28 newborns were admitted to NICU with hypernatremic dehydration. Literature review found 178 newborns with the same diagnosis since 1979 and detailed information was available for 150 patients. In the study and MEDLINE groups, respectively mean days of admission were 3.39 and 11.7; mean serum sodium, 156.5 and 178.6 mEq/L; and mean % weight loss, 11.5 and 25.7. Long-term follow up was performed in 15 patients from the study group, and two patients were found to be severely neurologically delayed. Five patients were found to have moderate risk scores by BINS tests. CONCLUSIONS: Early follow-up visits of newborns soon after discharge are important to determine risk for hypernatremic dehydration. Long-term follow up of this group of babies is also required to gather knowledge about the repercussions of early hypernatremic dehydration later in life.
