A 69-year-old woman with a 30-year history of rheumatoid arthritis (RA) on leflunomide presented with dizziness and weakness. Vital signs, cardiopulmonary auscultation, and laboratory studies were normal. The serological status of her RA was unknown. She exhibited ulnar deviation and swan-necking of the hands but no nodular skin lesions. She was an active smoker. Chest radiography revealed an opacity in the right lung. Computed tomography (CT) showed multiple pulmonary nodules and a dominant thick-walled cavitary mass in the periphery of the right lower lobe [Figure 1A]. Due to concern for a malignancy or infection, she underwent a bronchoscopy with a biopsy of the mass, which was non-diagnostic. A subsequent transthoracic needle biopsy demonstrated a central zone of necrosis surrounded by a cuff of palisading epithelioid histiocytes with the presence of occasional giant cells [Figure 1B]. There was no malignancy, and stains for micro-organisms were negative. In this clinical context, biopsy results were consistent with a pulmonary rheumatoid nodule (PRN).

Gastric perforation secondary to foreign body ingestion is rare. While obvious signs of acute abdomen usually lead to a prompt diagnosis by emergency department (ED) staff, this can be delayed in non-responsive or mentally disabled patients. An altered pain perception has been described in schizophrenia, as part of a complex phenomenon, which is thought to be unrelated to changes in nociceptive pathways. Cognitive impairment and negative symptoms may strongly influence the patient’s expression of pain [1].

Recent studies using propensity score matching have clearly indicated that contrast nephropathy following computed tomography occurs in hospitalized patients with advanced chronic kidney disease (eGFR < 30 ml/min/1.73 m2) and that this iatrogenic complication is likely underestimated because of concomitant renal functional recovery, unrelated to the imaging procedure. These findings should be considered regarding contrast-enhanced studies in such patients.

Background: Depression has been shown to be associated with cervical tumors (CTs), an association mostly demonstrated in studies in which temporality could not have been ascertained.

Objectives: To study the association between depression and CTs and the influence of co-morbidities of this association in a large cohort study.

Methods: A retrospective computer-based cohort study was conducted. The cohort included 357,450 female members of Maccabi Healthcare Services. The cohort was classified as depressed or non-depressed using the International Classification of Diseases 9/10 codes. For each subgroup, demographic characteristics, behavioral characteristics, co-morbidities, and CTs diagnosis were obtained. The burden of co-morbidities was defined as the sum of major co-morbidities. We used zero-inflated negative binomial regression analysis due to over-dispersion to estimate the relative risk (RR) for CTs with 95% confidence interval (95%CI).

Results: Depression was diagnosed in 15,789 women. Among this group, CTs were diagnosed in 1585 (10.0%). Among the 341,661 non-depressed, CTs were diagnosed in 4185 (1.2%). After adjustment to age and socioeconomic status, the association between depression and CTs was RR=9.2 (95%CI 8.7–9.9, P-value < 0.0001). The association between depression and CTs increased as the burden of clinical conditions increased (P-value < 0.0001).

Conclusions: Women with depression are at a higher risk for CTs, especially among those who have several co-morbidities. Tighter gynecology surveillance is crucial among these women.

Global developmental delay (GDD), defined as a significant delay in two or more developmental domains (e.g., gross/fine motor, cognitive, speech/language, personal/social, activities of daily living), affects 1–3% of children. According to the Israeli Ministry of Health, thyroid function studies are not indicated in children with GDD unless there are systemic features suggestive of thyroid dysfunction (https://www.health.gov.il/hozer/mr36_2012.pdf). This approach also exists in other countries with newborn screening programs for congenital hypothyroidism.

We present the case of an infant with GDD, who despite normal newborn screening tests, underwent a repeated extended thyroid function analysis (including T3 levels) leading to a diagnosis of Allan-Herndon-Dudley syndrome, a rare genetic neurodevelopmental syndrome.

Background: Salmonella, Shigella, and Campylobacter are highly prevalent among children. Reports on risk factors of patients infected with all three pathogens, not simultaneously, are scarce.

Objectives: To identify risk factors for multiple infection with Salmonella, Shigella, and Campylobacter in the same child.

Methods: Using the Israel Sentinel Laboratory-Based Surveillance Network, we conducted a retrospective observational case-case–control study among children aged 0–9 years. A case was defined as a child infected with Salmonella, Shigella, and Campylobacter at different occasions between January 1999 and December 2020. A control was defined as a child infected with a single pathogen once, during the same period. Logistic regression models were applied to determine the association between multiple infections and demographic characteristics.

Results: We identified 109 cases (0.1%) infected with Salmonella, Shigella, and Campylobacter, and 86,511 controls (99.9%) infected with only one bacteria type. In a multivariable analysis, we showed that being Jewish (odds ratio [OR] 2.4, 95% confidence interval [95%CI] 1.3–4.4), having residency in Jerusalem (OR 3.2, 95%CI 1.3–7.7), or in the southern district (OR 3.7, 95%CI 1.5–8.8) were independent risk factors for multiple infection.

Conclusions: Although very rare, non-simultaneous infection with multiple bacteria does occur in Israel. National and local authorities should promote programs to encourage proper hygiene practices, which are culture-adjusted.

Background: Cystic periventricular leukomalacia (cPVL) is a strong indicator of subsequent motor and developmental impairments in premature infants. There is a paucity of publications on biomarkers of cPVL.

Objectives: To determine C-reactive protein (CRP) levels during the first week of life of preterm infants who later developed cPVL and to identify the association between CRP levels with perinatal factors.

Methods: We retrospectively included infants ≤ 32 weeks gestation and/or birth weights ≤ 1500 grams; 17 with a cranial ultrasound diagnosis of cPVL and 54 with normal ultrasounds. Serum CRP levels were measured during days 1-7 (CRP1–7d) of life and subdivided into two timing groups: days 1–3 (CRP1–3d) and days 4-7 (CRP4–7d).

Results: The cPVL group had significantly higher mean CRP4–7d levels compared to controls (12.75 ± 21.2 vs. 2.23 ± 3.1, respectively, P = 0.03), while CRP1–3d levels were similar. CRP1–7d levels were significantly correlated with maximal fraction of inspired oxygen during the first 12 hours of life (FiO2-12h, r = 0.51, P < 0.001]. Additional risk factors were not associated with CRP levels.

Conclusions: Our finding of elevated CRP4-7d levels and later development of cPVL supports earlier studies on the involvement of inflammation in the pathogenesis of cPVL. Whether CRP could serve as a biomarker of cPVL and its correlation with outcomes, awaits further trials. Furthermore, the correlation between FiO2-12h and CRP1–7d levels suggest that hypoxia and/or hyperoxia may serve as a trigger in the activation of inflammation during the first days of life of preterm infants

Background: Management of acquired laryngotracheal stenosis (LTS) is challenging and often requires recurrent procedures.

Objectives: To compare the efficacy and safety of balloon dilatation (BD) versus rigid dilatation (RD) in the treatment of LTS.

Methods: A retrospective study of patients undergoing endoscopic intervention for LTS was performed.

Results: The study included 69 balloon (BD) and 48 rigid dilations (RD). Most cases were grade 3 Cotton-Meyer stenosis. Mean time interval to recurrence after BD and RD were 27.9 and 19.6 weeks, respectively. Remission of over 8 weeks was achieved in 71% of BD compared to 31.2% of RD (P < 0.05). In the BD group, dilatation of subglottic stenosis showed higher rates of remission of over 8 weeks compared to upper and mid-tracheal stenosis (92% vs. 62% and 20%, respectively, P < 0.05). Complications were encountered in 4.2% of RD and 2.9% of BD.

Conclusions: BD and RD are effective and safe procedures. Overall, BD achieved slightly better long-term results compared to RD

Background: Dialysate purity contributes to the inflammatory response that afflicts hemodialysis patients.

Objectives: To compare the clinical and laboratory effects of using ultrapure water produced by a water treatment system including two reverse osmosis (RO) units in series, with a system that also includes an ultrapure filter (UPF).

Methods: We performed a retrospective study in 193 hemodialysis patients during two periods: period A (no UPF, 6 months) and period B (same patients, with addition of UPF, 18 months), and a historical cohort of patients treated in the same dialysis unit 2 years earlier, which served as a control group.

Results: Mean C-reactive protein, serum albumin and systolic blood pressure worsened in period B compared to period A and in the controls.

Conclusions: A double RO system to produce ultrapure water is not inferior to the use of ultrapure filters.

Background: Previous surveys demonstrated variations in the clinical practices relating to the treatment and screening of maternal thyroid dysfunction.

Objectives: To study the current practices in the management of subclinical hypothyroidism (SCH) and thyroid nodules during pregnancy of obstetricians/gynecologists (OB/GYNs) and endocrinologists in Israel.

Methods: An electronic questionnaire was sent by email to all members of the Israeli Endocrine Society and the Israel Society of Obstetrics and Gynecology. Questionnaires included demographic data and clinical scenarios with questions regarding the screening and management of pregnant women with SCH, hypothyroxinemia, and a palpable thyroid nodule. The questionnaire for OB/GYNs was slightly modified.

Results: We received 90 responses from endocrinologists and 42 responses from OB/GYNs. Among endocrinologists, 39% would repeat a thyroid-stimulating hormone (TSH) test of 2.9 mU/L with normal free thyroxine and treat with thyroxine if the second result was above 2.5 mU/L. Among OB/GYNs, 73% would manage a woman with SCH at the beginning of her pregnancy by themselves and only 22% would start thyroxine after a first TSH result above 2.5 mU/L. Concerning screening, 57% endocrinologists and 71% OB/GYNs recommended screening for thyroid dysfunction in every woman at the beginning of her pregnancy. Among endocrinologists, 54% would order an ultrasound for a palpable thyroid nodule and perform a fine needle aspiration only for suspicious lesions.

Conclusions: The medical approach to thyroid disease in pregnant women remains a matter of controversy. Our results support the need for larger and prospective clinical studies.

Background: The human papillomavirus (HPV) test has proven to be efficient in triaging women with abnormal Pap findings in women with low cytological atypia, but there is no data about the accuracy for large loop excision of transformation zone in cases of recurrent atypia.

Objectives: To assess the clinical correlation between results of HPV typing and conization histology in women who had recurrent abnormal Pap test results with no colposcopy findings.

Methods: Our retrospective cohort study included 138 women enrolled in the Maccabi Healthcare Services who had consecutive atypical Pap test results for 2 years in which no abnormal colposcopic findings were detected. These women had an HPV typing and then conization.

Results: Among the total study population (n=138), 71.7% had negative histology, 19.6% had ≤ cervical intraepithelial neoplasia grade 1 (≤ CIN1), and 8.7% had CIN2+. With regard to HPV typing, 34.8% were negative and 65.2% were positive. Of those testing positive, 34.4% were positive for HPV 16 or 18. Sensitivity, specificity, positive predictive value, and negative predictive values of HPV typing for women were 89.7%, 44.4%, 38.9%, and 91.7%, respectively, and for HPV 16 or 18: 71.4%, 67.7%, 32.3%, and 100.0%, respectively. After stratification by cytological grades, for women with high-grade cervical cytology, the sensitivity and negative predictive values of the HPV typing were higher than among low-grade cervical cytology, while specificity and positive predictive values were lower.

Conclusions: HPV typing is a useful tool for the management of patients with persistently abnormal Pap test results.

Background: Radiation exposure is a well-known risk factor for well-differentiated thyroid cancer (WDTC). However, disease characteristics, optimal treatment, time from exposure to disease appearance, and the effect on outcome of age at initial exposure have yet to be determined. 

Objectives: To identify the characteristics of radiation-induced thyroid carcinoma.

Methods: We retrieved the charts of all patients previously exposed to radiation who were diagnosed with WDTC between the years 1985 and 2013 in a tertiary referral center. 

Results: Forty-four patients were reviewed. Median time from radiation exposure to diagnosis was 23 years. These patients had higher rates of aerodigestive symptoms and distant metastases on presentation than seen in non-radiated patients. Patients who were exposed to radiation before age 15 years tended to develop the disease at a younger age but had a longer latency period (34.7 ± 15.3 vs. 16.3 ± 10 years, P < 0.001) and none had significantly higher rates of vocal cord palsy, hoarseness on presentation, or aggressive variants on histology compared to patients exposed to radiation at an older age. Disease-specific survival (DSS) was the same for both groups and were similar to that seen in the general population (95% 20 year DSS).

Conclusions: Radiation-induced thyroid cancer has a more aggressive presentation and the age at exposure affects the presentation of disease. Nonetheless, appropriate treatment leads to a favorable prognosis.

Background: It has been suggested that sleep disordered breathing (SDB) during pregnancy may adversely influence maternal as well as fetal well being.

Objectives: To examine the effect of maternal SDB on neonatal neurological examination and perinatal complications.

Methods: Pregnant women of singleton uncomplicated pregnancies were prospectively recruited from a community and hospital low risk obstetric surveillance. All participants completed a sleep questionnaire in the second trimester and underwent ambulatory sleep evaluation (WatchPAT, Itamar Medical, Caesarea, Israel). They were categorized as SDB (apnea hypopnea index > 5) and non-SDB. Maternal and newborn records were reviewed and a neonatal neurologic examination was conducted during the first 48 hours. 

Results: The study group included 44 women and full-term infants; 11 of the women (25%) had SDB. Mean maternal age of the SDB and non-SDB groups was 32.3 ± 2.8 and 32.5 ± 4.7 years, respectively (P = 0.86). Mean body mass index before the pregnancy in the SDB and non-SDB groups was 25.8 ± 4.7 and 22.0 ± 2.5 kg/m2, respectively (P = 0.028). No differences were found between infants born to mothers with SDB and non-SDB in birth weight (3353.8 ± 284.8 vs. 3379.1 ± 492.4 g), gestational age (39.5 ± 0.9 vs. 39.2 ± 1.5 weeks), 5 minute Apgar scores (9.8 ± 0.6 vs. 9.9 ± 0.3), and neurologic examination scores (95.2 ± 3.9 vs. 94.6 ± 4.1). P value for all was not significant. 

Conclusions: Our preliminary results suggest that maternal mild SDB during pregnancy has no adverse effect on neonatal neurologic examination or on perinatal complications.
