OBJECTIVE: To discuss a case of pituitary abscess presenting with amenorrhea and diabetes insipidus, and to enumerate the differential diagnosis for this condition
SIGNIFICANCE: By presenting this case, the author aims to increase awareness regarding the possibility of infectious causes of pituitary masses, thereby prompting early recognition and treatment of similar cases
CASE REPORT: This is the case of a 42-year old woman admitted due to severe generalized headache, amenorrhea and polyuria of three months duration, preceded by a one-month history of remittent fever. Physical examination was normal except for bitemporal hemianopsia
LABORATORY TEST RESULTS: On admission, she had mild anemia, hypernatremia with elevated serum osmolality, and failure to concentrate urine. Hormonal examinations showed normal thyroxine and growth hormone levels, low basal serum cortisol, and elevated prolactin levels. Cranial CT scan showed widening of the sella turcica with a homogenous, isodense, slightly enhancing focus in the sellar and suprasellar area.
COURSE: Initial considerations were chiasmatic glioma versus a pituitary adenoma. Transphenoidal surgery was done and intraoperatively, purulent fluid was noted. Aspirate gram stain showed 1-2 white blood cells per high power field but with no growth on culture. Subsequently, vision was fully restored but prolactin levels continued to be slightly elevated. Basal cortisol and urine specific gravity were persistently low. Repeat CT scan showed disappearance of the pituitary mass. Six months after the operation, the patient was able to go back to work but continues to take steroids and carbamazepine for the diabetes insipidus.
REVIEW OF LITERATURE: There are about 100 cases of pituitary abscess in literature mimicking pituitary adenoma and presenting with headaches, amenorrhea, visual field cuts, hypopituitarism, fever and meningitis. As in this case, the abscess is frequently sterile. Pituitary abscess should be considered in patients with a primary diagnosis of pituitary adenoma with accompanying signs and symptoms suggestive of an infection. (Author)

BACKGROUND: Glutathione due to its favorable side effect of skin whitening has been used by cosmetic centers and by individuals buying it as an over the counter supplementation. Because of this, this compound is prone to misuse. To date, there are limited studies on the adverse effects of exogenous supplementation of glutathione.
OBJECTIVE: To determine the prevalence of thyroid dysfunction among individuals taking oral and intravenous glutathione
DESIGN: Cross-sectional study
METHODS:Healthy Filipino subjects, 21 to 50 years of age, currently taking oral or intravenous glutathione, with no preexisting/ known thyroid disease and history of radiation exposure, and not taking medications with known effect on thyroid function were included in the study. Blood extraction for thyroid function test and thyroid ultrasound were conducted.
RESULTS: A total of 36 subjects were analyzed with a mean age of 36.3±8 years, 86 percent were female. High dose glutathione (1000mg or more per day) was taken in by nine subjects (25%) while 27 subjects (75%) took doses below the recommended range (less than 1000ng per day). The prevalence of abnormal thyroid function was 5.56 percent (n=2). Both cases were taking low dose glutathione supplementation. No abnormal thyroid function was seen with higher doses of glutathione. No significant relationship was found between the duration of glutathione supplementation with thyroid function status. Thyroid stimulating hormone (TSH) levels were slightly higher among those taking high dose glutathione (mean=1.08 versus 1.04, p=.81). There was no significant differences in the duration and dose of supplementation with the size of the gland.
RECOMMENDATION:The direct effect of L-glutathione supplements on thyroid function must be established using a longitudinal prospective study design. We also propose a group to serve as a negative control during the comparisons.

Introduction: Type 2 diabetes mellitus (DM) is one of the leading non-communicable causes of death in the Philippines with a prevalence of 5.4% and its pathogenesis includes insulin resistance correlated with excess weight and BMI. Asian-based studies have shown that serum C-peptide is strongly associated with newly diagnosed diabetes and has a linear increasing trend with BMI, hence, this study aimed to determine the correlation of body mass index (BMI) with fasting C-peptide levels in Filipino patients with newly diagnosed type 2 DM. Also, to determine the correlation of fasting C-peptide, markers of insulin secretion and sensitivity (Homeostasis Model Assessment of beta cell function and insulin resistance: HOMA-IR, HOMA-B) with other metabolic parameters in newly diagnosed diabetics: waist circumference, HbA1C, fasting blood sugar (FBS), lipid profile. Methods: This cross-sectional study included 35 treatment naïve, newly diagnosed type 2 DM Filipino patients evaluated with anthropometric measurements, fasting C-peptide, and other metabolic parameters. The correlations among fasting C-peptide, BMI, waist circumference, FBS, HbA1c, lipid profile, HOMA-IR, and HOMA-B were determined using Pearson correlation. Results: A significant positive relationship were observed between BMI and HOMA-IR(r=0.335); C-peptide and waist circumference (r=0.363); C-peptide and HOMA-B(r=0.357); HOMA-IR and C-peptide (r=0.892); HOMA-IR and waist circumference (r=0.438); HOMA-IR and triglycerides (r=0.543). HOMA-B was negatively correlated with FBS and HbA1C (r=- 0.771, and r=-0.641, respectively). No correlation was seen between BMI and C-peptide (p=0.61). Conclusion Body mass index (BMI) is not correlated with fasting C-peptide levels in newly diagnosed type 2 DM Filipino patients. The positive relationship between C-peptide, waist circumference, and HOMA-IR merits further evaluation with larger studies.

Introduction: Given the increasing burden of diabetes worldwide as well as in the Philippines, understanding factors affecting diabetes management is crucial. We investigated the factors leading to poor adherence to titration of longacting, once a day, basal insulin among patients with type 2 diabetes mellitus (DM) seen at the outpatient department (OPD) clinics of St. Luke’s Medical Center, Quezon City. Methods: This qualitative study included semi-structured individual interviews and focus group discussions (FGD). A total of 43 type 2 DM patients using once a day, basal insulin participated. 22 patients had one-on-one interviews while 21 patients were divided into three separate FGDs. Data were analyzed using thematic analysis. Results: More than half (53.5%) of the type 2 DM patients included in this study did not have any method of titration of their once-daily basal insulin despite being taught by their attending physicians. The categorized themes identified were the following: patient-centered, treatment-related, healthcare system-related, and psychological/social factors. Conclusion Lack of income or financial support, fear of insulin injection and its side effects, high cost of insulin, inaccessibility of medical assistance from healthcare facilities, negative attitude/fear of titration, and difficulty complying to lifestyle changes were some of the identified factors leading to poor adherence to the titration of once-daily basal insulin in this study. Good, constant communication between the patient and the doctor appears to improve adherence to insulin dose titration. Future studies may adapt the themes and concepts identified to improve adherence to titration of once-daily basal insulin among patients with type 2 DM.
