Purpose:
To compare the 18F-NaF PET/CT studies (18F-NaF) with other imaging methods in the detection of skeletal metastases (SM) in patients with medullary thyroid cancer (MTC).
Methods:
We retrospectively analyzed 31 patients with MTC who performed 18F-NaF to assess SM. The results of the 18F-NaF were compared with other imaging methods performed for metastasis detection: 99Tc-MDP bone scan (BS), magnetic resonance imaging (MRI), contrast-enhanced CT (CT), and 68Ga-Dotatate and 18F-FDG PET/CT studies. A qualitative analysis comparing the 18F-NaF findings with the ones of the other methods was performed, and the results were classified as superior (>), equal (=), and inferior (<).
Results:
Eleven patients had no bone metastases detected on any of the imaging methods used. Twenty patients presented SM depicted on 18F-NaF. Of these 20 patients, 12 performed bone scan (in 9 18F-NaF > BS and in 3 188F-NaF = BS), 1 performed 18F-FDG (18F-NaF >18F-FDG), 4 performed 18Ga-Dotatate (in 2 18F-NaF >18Ga-Dotatate and in 2 18F-NaF = 18Ga-Dotatate), 20 performed CT of at least one body segment (in 15 18F-NaF = CT and in 5 18F-NaF > CT), and 16 performed MRI of at least one body segment, and in all of them, the 18F-NaF was equal to the MRI. Beside this, the 18F-NaF detected SM in body segments not routinely scanned in MRI and CT.
Conclusion
In patients with MTC, the 18F-NaF seems to be equal or superior to other imaging modalities in the detection of SM and allows the analysis of the whole skeletal in a single study.

Introduction:
There has been an increasing awareness of the effects of combining bromocriptine-QR with other medications for diabetes mellitus type 2. This study aimed to assess the efficacy and safety of bromocriptine-QR as an adjunctive therapy for patients with uncontrolled type 2 diabetes mellitus.
Methodology:
This systematic review is registered at the International Prospective Register of Systematic Reviews (CRD42022360326). Literature search was done via MEDLINE, NCBI, Google Scholar, Science Direct, Europe PMC and Cochrane Library databases. We included randomized controlled trials with participants 18 years old and above with uncontrolled type 2 diabetes mellitus. The primary outcome of interest is the efficacy and safety of bromocriptine-QR as an adjunctive therapy for glycemic control. Case reports, case series, reviews and animal studies were excluded. The risk of bias was reviewed using the Cochrane Risk of Bias tool. Meta-analysis was performed using Review Manager 5.4 and presented as a weighted mean difference and 95% confidence interval for changes from the baseline level.
Results:
Nine studies were included in the systematic review with a total of 2709 participants. The baseline HbA1c in the bromocriptine-QR group was 7.42% and 7.51% in the control group. The bromocriptine-QR group was favoured, outperforming the control group in terms of reducing hemoglobin A1c(HbA1c), with a statistically significant difference (weighted mean difference -0.6%; 95% CI [-0.83,-0.36]; p<0.00001). The most common side effects were nausea (33.75% vs 6.92%), fatigue (13.11% vs 5.94%), and headache (11.17% vs 6.87%).
Conclusion
Administration of bromocriptine-QR at a dose range of 1.6 to 4.8 mg/day as an adjunctive therapy reduced HbA1c and FBG in patients with uncontrolled type 2 diabetes mellitus (T2DM). However, there were also statistically greater odds of the occurrence of adverse events such as nausea, vomiting, and headache compared to controls.

Herein, we report a case of a 19-year-old man with multiple endocrine neoplasia type 2B (MEN2B) and medullary thyroid carcinoma (MTC) diagnosed when he was 12 years of age. The patient had previously undergone total thyroidectomy, cervical radiotherapy, and chemotherapy. He progressed with known bone, pulmonary, and lymph node metastases and was scanned with ¹⁸F-fluoride (¹⁸F-NaF) and ⁶⁸Ga-dotatate whole-body positron emission tomography/computed tomography (PET/CT) for metastatic disease monitoring.We found that the MTC bone metastases and soft tissue calcified metastases were better characterized on ¹⁸F-NaF PET/CT than on ⁶⁸Ga-dotatate PET/CT. This case illustrates that the ¹⁸F-NaF PET/CT could be helpful not only to the detection of bone metastases but also to the detection of calcified soft tissue metastases in patients with MTC.

Journal of the Philippine Dermatological Society 2018;27(2):86-90
Introduction:
Cutaneous leishmaniasis is non-endemic in the Philippines. Antiparasitic pentavalent antimonials are
acknowledged as first-line therapy for all forms of the disease. Amphotericin B is the second drug of choice but its use is
limited due to side effects.
Case Summary:
We present a case of a 32- year-old male overseas Filipino worker who presented with “volcaniform
plaques” (nodules and plaques with central crater) and surrounding satellite erythematous papules on the trunk, and
extremities after returning from Iraq. A diagnosis of cutaneous leishmaniasis was confirmed by the histopathologic
findings of a granulomatous inflammatory infiltrate with round to oval basophilic structures in the cytoplasm of
macrophages (Leishman bodies) in the dermis, which were highlighted prominently by Giemsa stain. The patient showed
poor response to treatment with 4 weeks of oral Rifampicin 1200 mg daily divided into 2 doses. He was shifted to oral
Itraconazole 400 mg daily divided into 2 doses for 6 weeks with dramatic improvement.
Conclusion
This case report highlights the favorable therapeutic response of cutaneous leishmaniasis to oral itraconazole
and hence, may be recommended as first-line medication to treat infected overseas workers from endemic areas who
seek treatment in the Philippines.

Introduction:
Cryptococcosis is an opportunistic fungal infection caused by Cryptococcus neoformans. This systemic
fungal infection affects 6 to 13% of patients with acquired immunodeficiency syndrome (AIDS). Only 10% of patients
with this condition develop cutaneous manifestations.
Case Summary:
A 20-year-old male, newly diagnosed case of HIV (Human Immunodeficiency Virus), presented with
multiple skin-colored molluscum contagiosum-like umbilicated papules on the face, neck and both arms. Lesions
increased in number rapidly and were associated with respiratory distress. Histopathologic examination revealed
findings of opportunistic fungal infection suggestive of cryptococcosis. Serum Cryptococcal Antigen Latex
Agglutination System (CALAS) test was also positive. Patient was then diagnosed as a case of cryptococcosis and was
a candidate for intravenous amphotericin B. However, before the planned medication was given, the patient
experienced severe respiratory distress and expired several hours later.
Conclusion
Molluscum-like skin lesions may be a telltale sign of a disseminated opportunistic fungal infection,
including Cryptococcosis. Early diagnosis followed by prompt and aggresive treatment would improve outcome and
survival of the patient.
