Tear film and meibomian gland functions in psoriasis

Tear secretion, tear film stability, and meibomian gland function (plugging, volume, and thickness) were assessed in patients with psoriasis vulgaris (n = 70). As compared to that of the healthy controls (n = 125) mean Schirmer I value of psoriatic patients was found to be in normal ranges, whereas tear film break-up time was significantly lowered. When evaluating meibomian gland function, psoriatic patients were found to have higher plugging and thickness indices but a normal volume of meibomian gland secretion. These findings suggested an obstructive type of meibomian gland dysfunction in psoriatic patients which might result from increased turnover of the epithelia lining the meibomian gland duct.

Cisplatin plus oral etoposide (EoP) combination is more effective than paclitaxel in patients with advanced breast cancer pretreated with anthracyclines: a randomised phase III trial of Turkish Oncology Group

Our objective was to determine whether oral etoposide and cisplatin combination (EoP) is superior to paclitaxel in the treatment of advanced breast cancer (ABC) patients pretreated with anthracyclines. From December 1997 to August 2003, 201 patients were randomised, 100 to EoP and 101 to paclitaxel arms. Four patients in each arm were ineligible. The doses of etoposide and cisplatin were 50 mg p.o. twice a day for 7 days and 70 mg m⁻² intravenously (i.v.) on day 1, respectively, and it was 175 mg m⁻² on day 1 for paclitaxel. Both treatments were repeated every 3 weeks. A median of four cycles of study treatment was given in both arms. The response rate obtained in the EoP arm was significantly higher (36.3 vs 22.2%; P=0.038). Median response duration was longer for the EoP arm (7 vs 4 months) (P=0.132). Also, time to progression was significantly in favour of the EoP arm (5.5 vs 3.9 months; P=0.003). Median overall survival was again significantly longer in the EoP arm (14 vs 9.5 months; P=0.039). Toxicity profile of both groups was similar. Two patients in each arm were lost due to febrile neutropenia. The observed activity and acceptable toxicity of EoP endorses the employment of this combination in the treatment of ABC following anthracyclines.

Predictive factors for the outcome of high flow nasal cannula therapy in a pediatric intensive care unit: Is the SpO2/FiO2 ratio useful?

OBJECTIVES

To determine the predictive factors for the outcome of high-flow nasal cannula (HFNC) therapy in a pediatric intensive care unit (PICU).

MATERIALS AND METHODS

We prospectively included all patients with acute respiratory distress/failure aged 1month to 18years who were admitted to the PICU between January 2015 and May 2016 and treated with HFNC as a primary support and for postextubation according to our pre-established protocol. HFNC failure was defined as the need for escalation to non-invasive ventilation (NIV) or invasive mechanical ventilation (MV). HFNC responders and nonresponders were compared based on clinical data obtained just before HFNC and at 30, 60, and 120min, 12, 24, and 48h, and at the end of therapy.

RESULTS

A total of 204 patients (median age: 16.5months) participated in the study. Twenty-six (12.7%) patients required escalation (4 to NIV and 22 to MV). Age >120months, higher PRISM-III and respiratory scores, and a lower SpO₂/FiO₂ (S/F) ratio at admission were predictors of HFNC failure. Achievement of the S/F>200 goal at 60min significantly predicted successful HFNC.

CONCLUSION

Monitoring the S/F ratio might be useful and practical to avoid delaying escalation to another ventilation support. Failure to achieve S/F>200 at 60min should be a warning for the escalation of respiratory support.

Appendicular metastasis from pancreatic adenocarcinoma

We present a 78-yr-old man with appendicular metastases from pancreatic adenocarcinoma. Barium enema X-ray showed incomplete filling of a distended appendix in a patient with abdominal discomfort. Colonoscopic evaluation revealed firm nodules in appendicular orifice. Histopathological examination of the nodule in the appendix revealed a metastatic adenocarcinoma. Abdominal computed tomography showed a low-density mass in the body of the pancreas. Endoscopic ultrasonography disclosed a hypoechoic mass in the body of the pancreas. Appendicular metastasis is extremely rare. To our knowledge, this is the second case of adenocarcinoma of the pancreas metastatic to the appendix in English language literature. A brief review of relevant literature is presented.

Traumatic globe luxation

A case of globe luxation which followed a relatively slight trauma is presented. The luxation was accompanied by laceration of the conjunctiva in this case. After achieving reposition in the emergency room, the patient underwent a surgical exploration of extraocular muscles and conjunctival fornices where many eyelashes were removed. The clinical features and management of globe luxation is discussed, importance of surgical exploration is emphasized.

High-dose ifosfamide by infusion with Mesna in advanced refractory sarcomas

Twenty patients with advanced sarcomas entered a pilot study with ifosfamide (IF) and mercaptoethane sulfonate sodium (Mesna) as a second-line treatment for six planned cycles. All patients had received prior doxorubicin- and cyclophosphamide-based chemotherapies. IF was administered at a dose of 3 g/m2 given as continuous intravenous infusion for 24 hr on day 1-5 with Mesna. In the absence of disease progression, chemotherapy was planned to be repeated every 4 weeks for six consecutive cycles. Following chemotherapy, only 2 patients (11%) achieved partial response with response durations of 6 and 9 months. There was no complete response. When considered for only high-grade tumors, the response rate reached up to 22%. Toxicity was reported for 48 cycles and the dose-limiting toxicities were myelosuppression (22%) and encephalopathy (17%). Chemotherapy protocol was changed after two or three courses in 16 patients with stable or progressive disease. IF/Mesna chemotherapy at this dose and schedule was not found to be very promising in refractory sarcomas as a second-line chemotherapy.

Maintenance therapy with alpha-interferon following first-line VAD in multiple myeloma

The aim of this study was to evaluate the response characteristics of vincristine, adriamycin and dexamethasone (VAD) as a first-line chemotherapy and to determine the efficacy of maintenance alpha-interferon (alpha-IFN) in multiple myeloma (MM). Between January 1985 and December 1994, a prospective trial was performed in stage II and III MM patients. The study population received only VAD with no maintenance therapy before 1990 (n=31), and those recruited after 1990 (n=33) were planned to be maintained with alpha-IFN (5 mU, 3 times per wk) during the plateau to a maximum of 2 yr. Median follow-up duration (44 vs. 39 months), time to response (3.4 vs. 3.5 months) and rate of objective response (61.3%, 19/31 and 63.6%, 21/33) were similar in VAD-only and VAD+IFN groups, respectively. The survival analyses revealed higher median progression-free (39.6 vs. 12 months) and overall survival (65+ vs. 24 months) durations in VAD+IFN group compared to VAD-only group. VAD regimen was well tolerated and IFN-related side effects were reversible. These findings denote that IFN maintenance prolongs the duration of response obtained by VAD.

Evaluation of the renal function using cystatin C level in the patients receiving cisplatin-based chemotherapy

OBJECTIVE

There are some data regarding the role of cystatin C, a cysteine proteinase inhibitor, in determining the glomerular filtration rate (GFR) more accurately. We aimed to evaluate the correlation of serum cystatin C levels with the serum creatinine levels and GFR calculated by Cockcroft-Gault and modification of diet in renal disease (MDRD) formulations in the patients who received cisplatin-based chemotherapy. We also intended to demonstrate its potential use in the early prediction of the renal function changes in these patients.

MATERIALS AND METHODS

In the study, 34 patients receiving cisplatin-based chemotherapy with various malignancies were included. The levels of cisplatin were determined prior to the chemotherapy and at the end of cisplatin infusion during the therapy. GFR was calculated by Cockcroft-Gault and MDRD formulations prior to the therapy and at the end of the third course.

RESULTS

A statistically significant linear correlation was found between the serum levels of cystatin C and creatinine prior to the chemotherapy (r = 0.42, p = 0.013). However, there was no correlation among the level of cystatin C subsequent to the cisplatin infusion and serum creatinine level following the third course and MDRD and creatinine clearance-Cockcroft-Gault formulations.

CONCLUSION

Even though the serum cystatin C levels were correlated with the serum creatinine levels in our study, it was concluded that it was not an appropriate parameter to predict the potential impairments in the renal function during the chemotherapy.

The significance of the bone marrow biopsy pattern in chronic lymphocytic leukemia: a prognostic dilemma

Although bone marrow biopsy pattern (BMBP) has long been suggested to be an independent prognostic factor in chronic lymphocytic leukemia (CLL), conflicting reports continue to appear in the literature. To investigate this issue we retrospectively reviewed 70 CLL patients who had undergone bone marrow biopsy at the time of diagnosis in a multivariate Cox regression analysis together with other prognostic factors. There were 51 (72.8%) males and 19 (27.2%) females with a median age of 60 years (range, 38-77). The median follow-up time was 24 months (range, 1-76), and median survival was 44 months. Thirtyfour patients (48.6%) had diffuse and 36 patients (51.4%) had nondiffuse BMBP (14 nodular, 11 interstitial, and 11 mixed). The median survival for diffuse and nondiffuse BMBP groups were 17 and 53 months, respectively (P= 0.05). Sixteen patients (22. 9%) had stage A, 28 (40.0%) stage B, and 26 (37.1%) stage C disease according to the Binet system, and four patients (5.7%) had low-risk, 39 (55.7%) intermediate-risk, and 27 (38.6%) high-risk disease according to the modified Rai staging system. The difference between the median survivals of patients in different stages was statistically significant (P < 0.0001). The BMBP and staging systems that are thought to be significant predictors of prognosis were used to build a multivariate Cox proportional hazard model. BMBP was not found to add additional information to the prognostic value of the staging systems. Our results underline two points: first, the significance of BMBP must be investigated in multivariate analysis including the stage, and second, BMBP is not a dynamic prognostic parameter, it is an index of tumor burden and does not add any prognostic information beyond that provided by clinical stage.

Ocular and periorbital anthropometric measurements in term Turkish newborns

This study was conducted in an effort to determine the normal landmarks in the eyelids and eyebrows of newborns and the relationships between them. We also correlated all measurements with gender and head circumferences. The anthropometric measurements were performed on 86 normal term newborns (40 males and 46 females) in the first 48 hours after delivery. There was no significant difference between either sex, or between the right and left eyes. In contrast, a statistically significant positive correlation was found between the head circumference and the horizontal fissure length (r = 0.42, p < 0.01). In addition, a significant correlation was found between the upper eyelid crease distance and the horizontal and the vertical fissure lengths (r = 0.27, p < 0.01; r = 0.22, p < 0.05, respectively). The results indicate that the normal eyelid crease location may be used as a landmark for guidance to plan surgical and reconstructive procedures.

Acute lymphoblastic leukaemia presenting with arthritis in an adult patient

The earliest manifestations of leukaemia often include rheumatic signs and symptoms. Arthritis is a well recognised complication of leukaemia in children, but acute and chronic leukaemia may also cause arthritis in adults. Leukaemic arthritis may occur at any time during the course of leukaemia and may be the presenting manifestation. It should therefore be considered in the differential diagnosis of both childhood and adult rheumatic disease. We present an adult patient presenting with arthritis due to acute leukaemia.

Good Tolerance of Weekly Irinotecan in a Patient with Metastatic Colorectal Cancer on Chronic Hemodialysis

Pharmacokinetic properties of many antineoplastic agents or their metabolites change with organ dysfunction. Unfortunately, chemotherapy doses determined in phase I and II studies in patients with normal hepatic and renal reserves are not usually applicable to those with hepatic and/or renal dysfunction. Considering the high incidence of colorectal adenocarcinoma, it is not unusual for a colorectal cancer patient to be on chronic hemodialysis. We report a patient with metastatic colorectal cancer on chronic hemodialysis who tolerated weekly irinotecan at 50 mg/m2 well without significant toxicity. We briefly discuss therapeutic dose modification in such patients.

The outcomes of children with tracheostomy in a tertiary care pediatric intensive care unit in Turkey

AIM

We aimed to describe which clinical characteristics were associated with the outcome of tracheostomy in our tertiary care pediatric intensive care unit.

MATERIAL AND METHODS

This was a retrospective review of medical records of pediatric patients who underwent tracheostomy in our Pediatric Intensive Care unit from 2008 to 2014 in Turkey.

RESULTS

Sixty-three patients were included the study. The median age of patients was 11 (range, 1-195) months. Twenty-five (39.7%) patients were female. The tracheostomy rate was 8.5% over a six-year period. Forty-nine (77.7%) patients were able to be discharged and sent home. The decannulation rate was 12.6% (n=8). The indications for tracheostomy were upper airway obstruction (n=9) and prolonged mechanical ventilation (n=54). The median intubation period before tracheostomy was 32 (range, 1-122) days and the median duration of pediatric intensive care unit stay after tracheostomy was 37 days. A total of 21 (52.5%) patients were weaned off mechanical ventilation. The rate of successful weaning from mechanical ventilation was higher in patients with upper airway obstruction than in those in the prolonged mechanical ventilation group (p=0.021). The complication rate was 25.3% in the pediatric intensive care unit and 11.1% at home.

CONCLUSIONS

Tracheostomy seems safe and improves pediatric patients' outcomes. The most important factor that affects the prognosis of children who underwent tracheostomy is the indication for tracheostomy. The outcomes are always better if the tracheostomy has been performed because of upper airway obstruction. Performing tracheostomy helps weaning from and off ventilator support and finally the discharge of patients with prolonged mechanical ventilation from the pediatric intensive care unit setting.

Early initiated feeding versus early reached target enteral nutrition in critically ill children: An observational study in paediatric intensive care units in Turkey

AIM

Although early enteral nutrition (EN) is strongly associated with lower mortality in critically ill children, there is no consensus on the definition of early EN. The aim of this study was to evaluate our current practice supplying EN and to identify factors that affect both the initiation of feeding within 24 h after paediatric intensive care unit (PICU) admission and the adequate supply of EN in the first 48 h after PICU admission in critically ill children.

METHODS

We conducted a prospective, multicentre, observational study in nine PICUs in Turkey. Any kind of tube feeding commenced within 24 h of PICU admission was considered early initiated feeding (EIF). Patients who received more than 25% of the estimated energy requirement via enteral feeding within 48 h of PICU admission were considered to have early reached target EN (ERTEN).

RESULTS

Feeding was initiated in 47.4% of patients within 24 h after PICU admission. In many patients, initiation of feeding seems to have been delayed without an evidence-based reason. ERTEN was achieved in 43 (45.3%) of 95 patients. Patients with EIF were significantly more likely to reach ERTEN. ERTEN was an independent significant predictor of mortality (P < 0.001), along with reached target enteral caloric intake on day 2 associated with decreased mortality.

CONCLUSIONS

There is a substantial variability among clinicians' perceptions regarding indications for delay to initiate enteral feeding in critically ill children, especially after the first 6 h of PICU admission. ERTEN, but not EIF, is associated with a significantly lower mortality rate in critically ill children.

The effect of dacryocystorhinostomy on tear film flow and stability in patients with chronic dacryocystitis

In 30 patients suffering from chronic dacryocystitis, tear film flow and stability were assessed by means of Schirmer I and break-up time tests before and after dacryocystorhinostomy. When compared with those of healthy individuals, mean values of Schirmer I tests were found to be decreased before dacryocystorhinostomy, but reached normal levels after a successful operation. Break-up time levels were found to be within normal limits before and after surgery and no statistically significant difference was observed between patients and control group. These findings not only confirm the previous findings, that tear secretion in patients with chronic dacryocystitis was reduced and break-up time was not affected, but also indicate that the reduction of tear secretion can be eliminated by a successful dacryocystorhinostomy.

Evaluation of 601 children with multisystem inflammatory syndrome (Turk MISC study)

PURPOSE

Due to its link with the 2019 coronavirus, the multisystem inflammatory syndrome in children (MISC) has garnered considerable international interest. The aim of this study, in which MISC patients were evaluated multicenter, and the data of the third period of the Turk-MISC study group, to compare the clinical and laboratory characteristics and outcomes of MISC patients who did and did not require admission to an intensive care unit (ICU).

METHODS

This retrospective multicenter observational study was carried out between June 11, 2021, and January 01, 2022. The demographics, complaints, laboratory results, system involvements, and outcomes of the patients were documented.

RESULTS

A total of 601 patients were enrolled; 157 patients (26.1%) required hospitalization in the intensive care unit (ICU). Median age was 8 years (interquartile range (IQR) 4.5-11.3 years. The proportion of Kawasaki disease-like features in the ICU group was significantly higher than in the non-ICU group (56.1% vs. 43.2% p = 0.006). The ICU group had considerably lower counts of both lymphocytes and platelets (lymphocyte count 900 vs. 1280 cells × μL, platelet count 153 vs. 212 cells × 103/ μL, all for p< 0.001). C-reactive protein, procalcitonin, and ferritin levels were significantly higher in the ICU group (CRP 164 vs. 129 mg/L, procalcitonin 9.2 vs. 2.2 μg/L, ferritin 644 vs. 334 μg/L, all for p< 0.001). Being between ages 5-12 and older than 12 increased the likelihood of hospitalization in the ICU by four [95% confidence intervals (CI)1.971-8.627] and six times (95% CI 2.575-14.654), respectively, compared to being between the ages 0-5. A one-unit increase in log D-dimer (µg/L) and log troponin (ng/L) was also demonstrated to increase the need for intensive care by 1.8 (95% CI 1.079-3.233) and 1.4 times (95% CI 1.133-1.789), respectively.     Conclusion: By comparing this study to our other studies, we found that the median age of MISC patients has been rising. Patients requiring an ICU stay had considerably higher levels of procalcitonin, CRP, and ferritin but significantly lower levels of lymphocyte and thrombocyte. In particular, high levels of procalcitonin in the serum might serve as a valuable laboratory marker for anticipating the need for intensive care.

WHAT IS KNOWN

• Lymphopenia and thrombocytopenia were an independent predictor factors in patients with MISC who needed to stay in intensive care unit. • The possibility of the need to stay in the intensive care unit in patients with MISC who had Kawasaki disease-like findings was controversial compared with those who did not.

WHAT IS NEW

• A one-unit increase log D dimer and log troponin was demonstrated to require for intensive care unit by 1.8 and 1.4 times, respectively. • Serum procalcitonin levels had the best performance to predict stay in the intensive care unit stay.

Primary neuroendocrine tumor of the breast

Adult neuroendocrine tumors may present with a wide range of clinical symptoms that share specific ultrastructural and biochemical features. A 63-year-old post-menopausal female patient was admitted to the hospital with a mass in her right breast and the diagnosis was primary neuroendocrine tumor of the breast. Although neuroendocrine tumors can originate in various parts of the body and breast carcinoma with neuroendocrine differentiation has been described, primary neuroendocrine tumor of the breast is very unusual. This case is now presented and the current literature is reviewed.

Cavernous hemangioma with cone dysfunction

We report a 13-year-old male who complained of strabismus and low visual acuity in the right eye. Saccular aneurysms filled with dark-colored blood were noted in the upper nasal quadrant of the right fundus. Ishihara color plates and Lanthony's new color test revealed a red-green color defect. Cone response and 30-Hz flicker responses were nearly absent. Cavernous hemangioma of the retina is a rare vascular hamartoma; the associated findings show cone dysfunction concomitant with this peripheral lesion.

The need for mechanical ventilation in a child exposed to a laundry detergent pod

Laundry detergent pods (LDPs) are a new, concentrated form of detergent covered by a membrane of polyvinyl alcohol or other water-soluble material. In contrast to traditional laundry detergents, the spectrum of responses to exposure to LDPs ranges from mild to life-threatening events. This is a case report of a 3-year-old male who ingested part of an LDP, leading to a depressed level of consciousness, upper airway obstruction, and severe respiratory distress. The patient required intubation and mechanical ventilation for 2 days before being discharged. This rare, severe clinical pattern demonstrates the potential toxicity of these laundry detergents. In the literature, few cases that required intubation and ventilation have been reported. To our knowledge, this is also the first case of LDP exposure reported from Turkey.
